     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. Unless
otherwise indicated, the information in this Prospectus assumes no exercise of
the over-allotment options granted to the Underwriters.
 
                                  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 (the "Concurrent Offering" 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 25 of its 30 networks. The Company is also certified
as a CLEC in 24 of its 30 networks. At September 30, 1996, the Company had a
total of 17 digital telephone switches installed in its networks. The Company
expects that, by the end of 1996,
 
                                        3
<PAGE>   6
 
switches will have been deployed to serve substantially all of the Company's
networks. The Company has increased the number of networks in operation or under
construction from 11 at December 31, 1994 to 30 at present. At September 30,
1996, the Company had a total of 787 route miles of optical fiber cable
installed, 358,640 voice grade equivalent (VGE) circuits in service, 13,107 CLEC
lines installed and 734 on-net and 913 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 11 7/8% Senior Discount Note Offering, (ii) the proposed sale
of $       Depositary Shares (see "Financing Plan" below), (iii) 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 (iv) the receipt of $7.6
million upon exercises of warrants and options to purchase an aggregate of
1,408,753 shares of Common Stock since September 30, 1996, the Company had cash,
cash equivalents and marketable securities of $      million, total assets of
$      million, long-term debt of $539.5 million and paid-in capital of $
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 17 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 expects to offer such services and products in substantially all of
     its operating networks by the end of 1996 and 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
     13,107 at September 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. Through the Company's prior investment
and a recent commitment, the Company has committed 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 Company and MaineCom intend to
contribute approximately $5.2 million and $3.5 million, respectively, to the
joint venture company. 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
11 7/8% Senior Discount Notes due November 1, 2006 (the "11 7/8% Senior Discount
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 1,551,083 shares upon exercise of warrants and options. On November   ,
     1996, the Company filed a Registration Statement on Form S-1 to register up
     to        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 "Concurrent
     Offering" below, "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 11 7/8% Senior Discount Notes, for which the
     Company received proceeds net of underwriting discounts of approximately
     $217.2 million (the "11 7/8% Senior Discount Note Offering"). 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 11 7/8%
     Senior Discount 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
 
                                        8
<PAGE>   11
 
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 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 "Concurrent Offering" 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.
 
     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."

      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

- ---------------
 (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, and as adjusted to reflect, (i) the
     sale of the 11 7/8% Senior Discount Notes on November 7, 1996, (ii) the
     exchange of minority interests for shares of Common Stock and the exercise
     of warrants and options since September 30, 1996 and (iii) the proposed
     sale of the Depositary Shares. 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 purchasing the shares of Common Stock offered hereby.
 
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 expects that,
by the end of 1996, it will have 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
 
                                       13
<PAGE>   16
 
and the deployment of switches in all of 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.
 
     At September 30, 1996, on a pro forma basis giving effect to the 11 7/8%
Senior Discount Note Offering and the conversion of the AT&T Credit Facility to
a parent company facility, the Company's total consolidated debt (including
current liabilities) was $560.9 million, of which $12.3 million were outstanding
liabilities of the Company's subsidiaries. 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
 
     The Company is a holding company which derives substantially all of its
revenues from its subsidiaries. As such, the Company is dependent to some extent
upon dividends and other payments from its subsidiaries to generate the funds
necessary to meet its cash obligations. 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 debt
agreements that may restrict the ability of certain 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" and "Management's Discussion and
Analysis of Financial Condition and Results of Operations -- Liquidity and
Capital Resources."
 
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
 
                                       14
<PAGE>   17
 
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 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
 
                                       15
<PAGE>   18
 
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 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 late 1996 or 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.
 
                                       16
<PAGE>   19
 
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.
 
SHARES OF COMMON STOCK ELIGIBLE FOR FUTURE SALE; POSSIBLE ADVERSE EFFECT ON
FUTURE MARKET PRICES
 
     Sales of substantial numbers of shares of Common Stock in the public market
could adversely affect the market price of the Common Stock and make it more
difficult for the Company to raise funds through future equity offerings. At the
request of the representatives of the Underwriters, all shares of Common Stock
(including shares issuable upon exercise of outstanding options and warrants to
purchase shares of Common Stock) held by the Selling Stockholders, except with
respect to shares offered hereby, are subject to contractual agreements pursuant
to which such shares cannot be sold, offered for sale or otherwise disposed of
for a period of 180 days after the date of this Prospectus without the prior
written consent of the designated representative of the Underwriters, except in
certain non-public transactions in which the acquiror or acquirors agree(s) to
such restrictions. Such stockholders will hold an aggregate of approximately
     % of the outstanding Common Stock upon completion of the Offering (see
"Principal and Selling Stockholders"). As a result, notwithstanding possible
earlier eligibility for sale under the provisions of Rules 144 and 701 under the
Securities Act, shares subject to such restrictions will not be saleable until
 
                                       17
<PAGE>   20
 
such restrictions expire or their terms are waived by the designated
representative of the Underwriters. Assuming the designated representative of
the Underwriters does not earlier release such stockholders from such
restrictions, at the end of such 180-day period, approximately      shares held
by such stockholders will be eligible for sale pursuant to Rules 144 and 701,
subject to the volume limitations thereof. There are options to purchase
3,002,022 shares of Common Stock outstanding as of November 15, 1996, of which
1,304,404 are exercisable within 60 days of November 15, 1996, and exercisable
warrants to purchase 409,860 shares of Common Stock outstanding as of November
15, 1996. See "Principal and Selling Stockholders," "Shares Eligible for Future
Sale" and "Description of Capital Stock -- Authorized Stock."
 
NO DIVIDENDS
 
     The Company does not anticipate paying dividends on the Common Stock for
the foreseeable future, and the ability of the Company to pay dividends on the
Common Stock is restricted by certain covenants in the Senior Discount Notes.
Further, the Depositary Shares being offered concurrently herewith will accrue
cumulative dividends at a rate of $     per annum and, so long as any Series D
Preferred Stock will be outstanding, the Company may not declare or pay any cash
dividends on the Common Stock unless all accrued and unpaid dividends on shares
of such preferred stock shall have been paid or declared and funds sufficient
for payment thereof set apart. The Company anticipates that it will reinvest its
earnings, if any, in the Company's businesses. See "Dividend Policy."
 
AUTHORIZED BUT UNISSUED STOCK; ANTI-TAKEOVER PROVISIONS
 
     The Company's Board of Directors has the authority to issue up to
           additional shares of Common Stock which have not been reserved for
outstanding warrants and employee stock plans or for issuance upon conversion of
the Depositary Shares and        shares of undesignated preferred stock and to
determine the price, rights, preferences and privileges of those preferred
shares without any further vote or action by the stockholders. The issuance of
such shares, while potentially providing desirable flexibility in connection
with possible future acquisitions, equity financings and other corporate
purposes, might have a dilutive effect on earnings per share and on the equity
ownership of holders of the Company's Common Stock and could have the effect of
making it more difficult for a third party to acquire a majority of the
outstanding voting stock of the Company. At present, there are no pending
proposals for the issuance of any of such additional authorized shares. In
addition, the Company has adopted a Stockholders Protection Rights Plan, and is
subject to the anti-takeover provisions of Section 203 of the General
Corporation Law of the State of Delaware which prohibits the Company from
engaging in a "business combination" with an "interested stockholder" for a
period of three years after the date of the transaction in which the person
became an interested stockholder, unless the business combination is approved in
a prescribed manner. Furthermore, the Company's Restated Certificate of
Incorporation provides that the Board of Directors is divided into three classes
with the directors serving staggered three-year terms. In addition, most of the
Company's existing indebtedness and employee stock plans are subject to
acceleration in the event of a change-in-control of the Company. Such agreements
and provisions could have the effect of delaying, deferring or preventing a
change-in-control of the Company by increasing the aggregate cost to potential
investors of an acquisition of the Company. See "Description of Capital Stock --
Authorized Stock," "-- Delaware Law and Certain Charter Provisions," "--
Preferred Stock Purchase Rights" and "-- Proposed Offering of Depositary
Shares."

                                DIVIDEND POLICY
 
     The Company has never declared or paid cash dividends on its capital stock.
Except with respect to cash dividends on the Depositary Shares, when, as and if
declared by the Board of Directors out of funds legally available therefor, the
Company currently intends to retain earnings, if any, to support its growth
strategy and does not anticipate paying cash dividends in the foreseeable
future. The ability of the Company to pay dividends is restricted by covenants
contained in the Senior Discount Notes.
 
     The Company is a holding company whose principal assets are the stock of
its operating subsidiaries. The principal internal sources of funds for the
Company are distributions from its subsidiaries. The ability of the Company's
subsidiaries to make such payments will be subject to, among other things, the
availability of sufficient funds and restrictive covenants in debt agreements
applicable to certain of such subsidiaries. However, the Company does not
believe that any such restrictions have had or will have any material impact on
the Company's ability to meet its cash obligations. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations -- Liquidity and
Capital Resources."

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.

 (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.
 (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

     of warrants and options since September 30, 1996 and (iii) the proposed
     sale of the Depositary Shares. See "Capitalization."

               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 17 digital telephone switches installed in its networks. The Company
expects to have switches deployed to offer local dial tone, switched access
termination and origination services, centrex, and desktop products in
substantially all of its operating networks by the end of 1996, and 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

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
 
                                       24
<PAGE>   27
 
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.
 
                                       25
<PAGE>   28
 
     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
 
                                       26
<PAGE>   29
 
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
measure commonly used in the telecommunications industry and is presented
 
                                       27

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.
 
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
committed 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.
 
                                       28
<PAGE>   31
 
     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 Company and MaineCom intend to contribute approximately $5.2 million and
$3.5 million, respectively, to the joint venture company. 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 11 7/8% Senior Discount Notes due November
1, 2006, for which the Company received proceeds net of underwriting discounts
of approximately $217.2 million. The 11 7/8% Senior Discount Notes will not
accrue cash interest until November 1, 2001, and thereafter cash interest will
accrue until maturity on the 11 7/8% Senior Discount Notes at a rate of 11 7/8%
per annum. The 11 7/8% Senior Discount Notes are redeemable at the option of the
Company, in whole or in part, at any time on or after November 1, 2001 at
certain redemption prices plus accrued and unpaid interest, if any, to the date
of redemption. In the event of a Strategic Equity Investment (as defined in the
Indenture governing the 11 7/8% Senior Discount Notes) on or before November 1,
1999, up to a maximum of 33 1/3% of the aggregate principal amount of the
11 7/8% Senior Discount 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 (as
defined in the Indenture) thereof. In the event of a Change of Control (as
defined in the Indenture), holders of the 11 7/8% Senior Discount Notes will
have the right to require the Company to purchase their 11 7/8% Senior Discount
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. The 11 7/8% Senior Discount 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
11 7/8% Senior Discount Note Offering and the conversion of the AT&T Credit
Facility to a parent company facility, the Company's total consolidated debt
(including current liabilities) was $560.9 million, of which $12.3 million were
outstanding liabilities of the Company's subsidiaries.
 
     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
 
                                       29
<PAGE>   32
 
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 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
 
                                       30
<PAGE>   33
 
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
 
                                       32
<PAGE>   35
 
     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 17 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 expects to offer such services and products in substantially all of
     its operating networks by the end of 1996 and 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
 
                                       33
<PAGE>   36
 
     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.
 
                                       34
<PAGE>   37
 
     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 13,107 at September 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 "The Competitive Local Telecommunications Industry," "Competition" and
"Regulatory Overview" below.
 
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
 
                                       35
<PAGE>   38
 
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 17 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 25 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
 
                                       36
<PAGE>   39
 
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
     consulting professionals combine extensive experience in telecommunications

          TELEDATA. Provides engineering and CAD services for the conversion of
     telecommunications systems, maps and drawings for use with applications on
     clients' automated mapping/ facilities management/geographical information
     systems (AM/FM/GIS).
 
          TELEMAP. Designs AM/FM/GIS software products for clients engaged in
     designing telecommunications networks.
 
          TELESYSTEMS. Designs and installs financial and management software
     products for telecommunications companies. Products include software for
     billing systems, toll rating, plant records and financial applications.
 
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
 
                                       37
<PAGE>   40
 
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."

     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. Through the Company's prior investment and a
recent commitment, the Company has committed 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 Company and MaineCom intend
to contribute approximately $5.2 million and $3.5 million, respectively, to the
joint venture company. 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.
 
                                       40
<PAGE>   43
 
     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
 
                                       41
<PAGE>   44
 
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,
 
                                       42
<PAGE>   45
 
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
 
                                       43
<PAGE>   46
 
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
 
                                       44
<PAGE>   47
 
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. 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 September 30, 1996, the Company had approximately 711 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
 
                                       47
<PAGE>   50
 
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 a total of 27 of its operating networks by the end of 1996 and all of
its operating networks by the end 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
 
                                       50
<PAGE>   53
 
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
 
                                       51
<PAGE>   54
 
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.

     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.

     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
 
                                       55
<PAGE>   58
 
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 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.
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.
 
                                       56
<PAGE>   59
 
     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 24 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.
 
     The Company has established interconnection agreements with ILECs for 25 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 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 Arizona and New Mexico which is scheduled to be completed by
late 1996 or 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.
 
                                       57

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.
 
     If any of the Company's existing franchise or license agreements were
terminated prior to its expiration date and the Company were forced to remove
its fiber from the streets or abandon its network in place, such termination
would have a material adverse effect on the Company's subsidiary in that
metropolitan area and could have a material adverse effect on the Company.

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
 
                                       70
<PAGE>   73
 
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 CAPITAL STOCK
 
     The Company is incorporated under the laws of the State of Delaware.
Accordingly, the rights of holders of the Company's Common Stock, Preferred
Stock, warrants and options are governed by the General Corporation Law of the
State of Delaware (the "DGCL") and by the Company's Restated Certificate of
Incorporation and By-laws. The following summary of such rights is qualified in
its entirety by reference to the DGCL and the Restated Certificate of
Incorporation and By-laws of the Company. Copies of such documents will be
provided to any stockholder upon request.
 
AUTHORIZED STOCK
 
     The Company is authorized to issue 50,000,000 shares of Common Stock, par
value $0.01 per share ("Common Stock"), and 1,040,012 shares of Preferred Stock,
par value $0.01 per share ("Preferred Stock"). Of the Common Stock, 49,669,100
shares are designated Voting Common Stock and 330,900 Shares are designated
Non-Voting Common Stock. Of the Preferred Stock, 50,000 shares are designated
Series C Junior Participating Preferred Stock,           are designated Series D
Conversion Preferred Stock and the remainder of the Preferred Stock has the
status of authorized and unissued shares of Preferred Stock subject to issuance
from time to time as new series of Preferred Stock created by resolution of the
Board of Directors. The shares of Series C Junior Participating Preferred Stock
are issuable upon exercise of the Preferred Stock Purchase Rights issued under
the Company's Shareholder Protection Rights Plan (see "--Preferred Stock
Purchase Rights" below).
 
     At November 15, 1996, the 31,063,623 outstanding shares of the Company's

60 days.
 
     The warrants and options are subject to adjustment from time to time in
order to prevent dilution of the exercise rights granted thereunder resulting
from (i) any subdivision or combination of the stock subject thereto, (ii) any
reorganization, reclassification, consolidation or merger of the Company or any
sale of the Company's assets, (iii) certain other dilutive events determined by
the Board of Directors of the Company to be dilutive in nature and of the type
for which adjustment should be made and (iv) in the case of the warrants, the

below the exercise prices thereof.
 
REDEMPTION
 
     There are no redemption or sinking fund provisions applicable to the Common
Stock.
 
LIQUIDATION
 
     Upon liquidation, dissolution or winding up of the Company, the holders of
Common Stock are entitled to receive pro rata the assets of the Company which
are legally available for distribution, after payment of all debts and other
liabilities and subject to the prior rights of holders of any Preferred Stock
then outstanding.
 
NO CUMULATIVE VOTING
 
     There is no cumulative voting. Therefore, the holders of a majority of the
shares of Common Stock voted in an election of directors will be able to elect
all of the directors then standing for election, subject to any rights of the
holders of any outstanding Preferred Stock.

DIVIDEND POLICY
 
     The Company has never declared or paid cash dividends on its capital stock.
Except with respect to cash dividends on the Depositary Shares, when, as and if
declared by the Board of Directors out of funds legally available therefor, the
Company currently intends to retain all future earnings, if any, to support its
growth strategy and does not anticipate paying cash dividends in the foreseeable
future. See "Dividend Policy."
 
STOCKHOLDER ACTION WITHOUT A MEETING AND POWER TO CALL SPECIAL MEETINGS
 
     Under the DGCL, any corporate action which may be taken at any annual or
special meeting of stockholders may be taken without a meeting by the written
consent of not less than the minimum number of votes that would be necessary to
authorize or take such action at a meeting if a meeting were held to approve
such action. The DGCL further provides that prompt notice of any action taken
without a meeting must be given to all stockholders who have not consented. The
Company's By-laws provide that special meetings of the Company's stockholders
may be called by any two members of the Board of Directors or by the Chairman of
the Board.
 
BOARD OF DIRECTORS
 
     The number of directors which constitutes the entire Board of Directors of
the Company is ten (10). The Company's Restated Certificate of Incorporation
provides for three classes of directors having staggered terms of office with
each director elected to serve a three year term. See "Management."
 
LIMITATION ON PERSONAL LIABILITY OF DIRECTORS
 
     Delaware law authorizes a Delaware corporation to eliminate or limit the
personal liability of a director to a corporation and its stockholders for
monetary damages for breach of certain fiduciary duties as a director. The
Company believes that such a provision is beneficial in attracting and retaining
qualified directors, and, accordingly, the Company's Restated Certificate of
Incorporation includes a provision eliminating liability for monetary damages
for any breach of fiduciary duty as a director, except: (1) for any breach of
the duty of loyalty to the Company or its stockholders; (2) for acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of law; (3) for any transaction from which the director derives an
improper personal benefit; and (4) for unlawful payments of dividends or
unlawful stock repurchases or redemptions as provided in Section 174 of the
DGCL. Thus, pursuant to Delaware law, directors of the Company are not insulated
from liability for breach of their duty of loyalty (requiring that, in making a
business decision, directors act in good faith and in the honest belief that the
action is taken in the best interests of the Company) or for claims arising
under the federal securities laws. The foregoing provisions of the Company's
Restated Certificate of Incorporation may reduce the likelihood of derivative
litigation against directors and may discourage or deter stockholders or
management from bringing a lawsuit against directors for breaches of their
fiduciary duties, even though such an action, if successful, might otherwise
have benefitted the Company and its stockholders. Further, the Company's
Restated Certificate of Incorporation contains provisions for the
indemnification of and advancing of expenses to directors and officers to the
full extent permitted by law. The Company has insurance with a policy limit of
$10 million for the benefit of its officers and directors insuring such persons
against certain liabilities, including certain liabilities under the securities
laws.
 
VOTE REQUIRED FOR AMENDMENTS
 
     The Company's Restated Certificate of Incorporation requires the
affirmative vote of the holders of record of outstanding shares representing at
least 66 2/3% of all the outstanding capital stock of the Company entitled to
vote generally in the election of directors to amend, alter, change or repeal,
or
 
                                       73
<PAGE>   76
 
adopt any provision or provisions inconsistent with, Article Fourth of the
Restated Certificate of Incorporation, which sets forth the authorized capital
stock of the Company and the terms thereof.
 
     The Restated Certificate of Incorporation of the Company allows the Board
of Directors to adopt, amend, or repeal the By-laws, subject to the right of the
Company's stockholders entitled to vote with respect thereto to adopt, amend or
repeal the By-laws. The By-laws provide that they may be altered, amended or
repealed by (i) the affirmative vote of at least 66 2/3% of the members of the
Board of Directors present at a meeting at which a quorum is present or (ii) the
holders of 66 2/3% of the issued and outstanding shares of stock entitled to
vote generally at a meeting of stockholders, voting as a single class. This
provision would enable holders of more than 33 1/3% of the voting power to
prevent an amendment to the By-laws by the stockholders even if it were favored
by the holders of a majority of the voting stock.
 
DELAWARE LAW AND CERTAIN CHARTER PROVISIONS
 
     Section 203 of the DGCL requires that certain types of business
combinations (including mergers, combinations, and sales or other dispositions
of significant assets of a corporation) may not be accomplished with an
interested stockholder (generally, any person holding 15% or more, directly or
indirectly through affiliates or associates, of the issued and outstanding
shares of voting stock of a corporation) within three years of the date the
person became an interested stockholder unless: (i) prior to such date the Board
of Directors of the corporation approved of the business combination or
transaction which resulted in the stockholder becoming an interested
stockholder; or (ii) upon consummation of the transaction which resulted in the
stockholder becoming an interested stockholder, the interested stockholder owned
at least 85% of the voting stock (excluding shares of stock owned by persons who
are both directors and officers, and by certain employee stock plans); or (iii)
on or subsequent to such date, the business combination is approved by the Board
of Directors and by the affirmative vote of stockholders holding at least
66 2/3% of the issued and outstanding voting stock of the corporation. Section
203 is applicable to the Company.
 
CERTAIN EFFECTS OF AUTHORIZED BUT UNISSUED STOCK
 
     Following completion of the Depositary Shares Offering, there will be
       additional authorized shares of Common Stock which have not been reserved
for issuance upon conversion of the Depositary Shares, upon exercise of
outstanding warrants and options and under employee stock plans and
authorized shares of Preferred Stock available for issuance by the Company at
such times and under such circumstances as may be determined by the Board of
Directors, and, in the case of the Preferred Stock, with such designations,
rights and preferences as may be determined by the Board of Directors. Such
shares will be available for possible future acquisitions, equity financings and
other corporate purposes, and might be issued at such times and under such
circumstances as to have a dilutive effect on earnings per share and on the
equity ownership of holders of the Company's Common Stock. The ability of the
Company's Board of Directors to issue additional shares of stock could enhance
the Board's ability to negotiate on behalf of stockholders in a takeover
situation but could also be used by the Board to make a change in control more
difficult and could increase the ability of the Board to continue current
management. At present, there are no pending proposals for the issuance of any
such additional authorized shares.
 
PREFERRED STOCK PURCHASE RIGHTS
 
     Under the Company's Stockholders Protection Rights Plan (the "Rights
Plan"), the Board of Directors has declared and paid a dividend of one Preferred
Stock Purchase Right (a "Right") for each outstanding share of Common Stock.
Except as set forth below, each Right, when exercisable, entitles the registered
holder to purchase from the Company one one-thousandth of a share of Series C
Junior Participating Preferred Stock, $.01 par value (the "Series C Preferred
Stock"), at a price of $100.00 per one one-thousandth of a share (the "Purchase
Price"), subject to adjustment. The terms of the Rights are set forth in the
Rights Agreement between the Company and Boatmen's
 
                                       74
<PAGE>   77
 
Trust Company, as Rights Agent (the "Rights Agreement"), and the summary of the
terms of the Rights set forth herein is qualified in its entirety by reference
to the Rights Agreement.
 
     Currently, no separate Rights certificates represent the Rights. Until the
earlier of (i) 10 business days following the first to occur of (a) a public
announcement by the Company or an Acquiring Person (defined below) that, without
the prior written consent of the Company, a person or group of affiliated or
associated persons, other than the Company or subsidiaries or employee benefit
or compensation plans of the Company (an "Acquiring Person"), has acquired, or
obtained the right to acquire, 20% or more of the voting power of all securities
of the Company then outstanding and generally entitled to vote for the election
of directors of the Company ("Voting Power"), or (b) the date on which the
Company first has notice or otherwise determines that a person has become an
Acquiring Person (the "Stock Acquisition Date"), or (ii) 10 business days (or
such later date as may be determined by the Board of Directors prior to the time
that any person becomes an Acquiring Person) after the date that a tender offer
or exchange offer is first published or sent, without the prior written consent
of a majority of the Board of Directors, that will result in any person owning
20% or more of the Voting Power (the earlier of the dates in clause (i) or (ii)
above being called the "Distribution Date"), the Rights will be evidenced by the
Company's outstanding Common Stock certificates. Notwithstanding the foregoing,
an Acquiring Person shall not include any person or group who inadvertently
becomes the beneficial owner of 20% or more of the Voting Power, as long as such
person or group promptly enters into an irrevocable commitment to, and promptly
does, divest enough shares to get below the 20% threshold.
 
     The Rights Agreement provides that, until the Distribution Date, the Rights
will be transferable only in connection with the transfer of the Company's
Common Stock. Until the Distribution Date (or earlier redemption, termination or
expiration of the Rights), newly issued Common Stock certificates will contain a
notation incorporating the Rights Agreement by reference. Until the Distribution
Date (or earlier redemption, termination or expiration of the Rights), the
surrender for transfer of any of the Company's outstanding Common Stock
certificates will also constitute the transfer of the Rights associated with the
Common Stock represented by such certificate. As soon as practicable following
the Distribution Date, separate certificates evidencing the Rights ("Right
Certificates") will be mailed to holders of record of the Company's Common Stock
as of the close of business on the Distribution Date and such separate
certificates alone will then evidence the Rights.
 
     The Rights are not exercisable until the Distribution Date. The Rights will
expire on February 28, 2006, unless such date is extended or unless earlier
redeemed or exchanged by the Company, as described below.
 
     The Purchase Price payable, the number and identity of shares of Series C
Preferred Stock or other securities or property issuable upon exercise of the
Rights and the number of Rights outstanding are subject to adjustment from time
to time to prevent dilution (i) in the event of a stock dividend on, or a
subdivision, combination or reclassification of, the Series C Preferred Stock,
(ii) upon the issuance to holders of Series C Preferred Stock of rights or
warrants to subscribe for shares of Series C Preferred Stock or securities
convertible into Series C Preferred Stock at less than the then current market
price of the Series C Preferred Stock, or (iii) upon the distribution to holders
of Series C Preferred Stock of evidences of indebtedness or cash (excluding
regular periodic cash dividends out of earnings or retained earnings of the
Company), assets (other than a dividend payable in Series C Preferred Stock) or
convertible securities, subscription rights or warrants (other than those
referred to above).
 
     The number of outstanding Rights and the number of one one-thousandths of a
share of Series C Preferred Stock issuable upon exercise of each Right are also
subject to adjustment in the event of a subdivision, combination or
consolidation of the Common Stock or a stock dividend on the Common Stock
payable in Common Stock occurring, in any such case, prior to the Distribution
Date.
 
                                       75
<PAGE>   78
 
     With certain exceptions, no adjustments in the Purchase Price will be
required until cumulative adjustments require an adjustment of at least 1% in
such Purchase Price. No fractional shares will be issued (other than fractions
which are integral multiples of one one-thousandth of a share of Series C
Preferred Stock). In lieu of fractional shares, an adjustment in cash will be
made based on the market price of the stock on the last trading date prior to
the date of exercise.
 
     In the event that, following the Distribution Date, (i) the Company
consolidates with or merges with or into any person, (ii) any person
consolidates with or merges with or into the Company, and the Company continues
or survives such merger and, in connection with such merger, all or part of the
Common Stock is changed into or exchanged for stock or securities of another
person or cash or any other property or (iii) the Company (or one or more of its
subsidiaries) sells or transfers 50% or more of the Company's assets or earning
power (in one transaction or a series of transactions), proper provision shall
be made so that each holder of a Right shall thereafter have the right to
receive, upon the exercise of such Right and payment of the Purchase Price, that
number of shares of common stock of the surviving or purchasing company (or, in
certain cases, one of its affiliates) which at the time of such transaction
would have a market value of two times the Purchase Price (such right being
called the "Merger Right").
 
     In the event that any person shall become an Acquiring Person ("Flip-in
Event"), proper provision shall be made so that each holder of a Right will
thereafter have the right to receive upon exercise that number of shares (or
fractional shares) of Common Stock (or, in certain cases, equivalent securities)
having a market value of two times the Purchase Price (such right being called
the "Subscription Right"). However, the Rights will not become exercisable
following a Flip-in Event as described above until such time as the Rights are
no longer redeemable by the Company as described below.
 
     Any Rights that are beneficially owned by an Acquiring Person or an
affiliate or an associate of an Acquiring Person will become null and void upon
the occurrence of any of the events giving rise to the exercisability or the
Subscription Right or the Merger Right, and any holder of such Rights will have
no right to exercise such Rights from and after the occurrence of such an event
insofar as they relate to the Subscription Right or the Merger Right.
 
     At any time after the acquisition by a person or group of affiliated or
associated persons of beneficial ownership of 20% or more of the Voting Power
and prior to the acquisition by such person or group of 50% or more of the
Voting Power, the Board of Directors of the Company may exchange the Rights
(other than Rights owned by such person or group which have become void), in
whole or in part, at an exchange ratio of one share of Common Stock, or one
one-thousandth of a share of Series C Preferred Stock (or of a share of the
Company's Preferred Stock having equivalent rights, preferences and privileges),
per Right (subject to adjustment).
 
     At any time prior to the Distribution Date, the Company may elect to redeem
the Rights in whole, but not in part, at a price of $0.001 per Right as adjusted
to reflect any stock split, stock dividend or similar transaction. Upon the
effective date of the redemption, the right to exercise the Rights will
terminate and the only right thereafter of the holders of Rights will be the
right to receive the redemption price. The Company shall promptly and publicly
disclose any such redemption and provide notice of such redemption to Rights
holders within 10 days after the Board action. However, any failure to give, or
defect in, such disclosure will not affect the validity of such redemption.
 
     The Series C Preferred Stock purchasable upon exercise of the Rights will
not be redeemable and will be junior to any other series of Preferred Stock the
Company may issue (unless otherwise provided in the terms of such stock). Each
share of Series C Preferred Stock will have a preferential dividend in an amount
equal to the greater of $10.00 per share or 1,000 times any dividend declared on
each share of Common Stock. In the event of liquidation, the holders of Series C
Preferred Stock will be entitled to a minimum preferential liquidation payment
of $1,000 per share (plus any accrued but unpaid dividends) and, after payment
of an equivalent amount to holders of the Common Stock, to share ratably and
proportionately with the Common Stock in the distribution of any remaining
 
                                       76
<PAGE>   79
 
assets. Each share of Series C Preferred Stock will have 1,000 votes, voting
together with the shares of Common Stock. In the event of any merger,
consolidation or other transaction in which shares of Common Stock are
exchanged, each share of Series C Preferred Stock will be entitled to receive
1,000 times the amount and type of consideration received per share of Common
Stock. The rights of the Series C Preferred Stock as to dividends, liquidation
and voting, and in the event of mergers and consolidations, are protected by
customary anti-dilution provisions. Fractional shares of Series C Preferred
Stock in integral multiples of one one-thousandth of a share of Series C
Preferred Stock will be issuable; however, the Company may elect to distribute
depositary receipts in lieu of such fractional shares. In lieu of fractional
shares other than fractions that are multiples of one one-thousandth of a share,
an adjustment in cash will be made based on the market price of the Series C
Preferred Stock on the last trading date prior to the date of exercise.
 
     Because of the nature of the Series C Preferred Stock's voting, dividend
and liquidation features, the value of the one one-thousandth of a share of
Series C Preferred Stock purchasable upon exercise of each Right should
approximate the value of one share of Common Stock.
 
     The Board of Directors of the Company retains a broad ability to amend or
supplement the Rights Agreement without the consent of the holders of the
Rights, including amendments to extend the expiration date of the rights and
lower the threshold for exercisability of the Rights from 20% to not less than
the greater of (i) any percentage greater than the largest percentage of the
Voting Power then known to the Company to be beneficially owned by any person or
group of affiliated or associated persons (other than subsidiaries or employee
benefit or compensation plans of the Company), and (ii) 10%, except that from
and after such time as any person becomes an Acquiring Person no such amendment
may adversely affect the interests of the holders of the Rights.
 
     Until a Right is exercised, the holder thereof, as such, will have no
rights as a shareholder of the Company, including, without limitation, the right
to vote or to receive dividends.
 
     Shareholders may, depending upon the circumstances, recognize taxable
income in the event that the Rights become exercisable for Series C Preferred
Stock or other consideration as set forth above.
 
     The Rights have certain anti-takeover effects. The Rights may cause
substantial dilution to a person or group that attempts to acquire the Company
without a condition to such an offer that a substantial number of the Rights be
acquired or the Rights be redeemed or otherwise not apply. The Company's ability
to amend the Rights Agreement may, depending upon the circumstances, increase or
decrease the anti-takeover effects of the Rights. The Rights do not prevent the
Board of Directors of the Company from approving in advance any merger or other
business combination since the Rights may be redeemed by the Board of Directors
as described above.
 
PROPOSED OFFERING OF DEPOSITARY SHARES
 
     The Company has filed a Registration Statement on Form S-1 to register up
to        Depositary Shares,        shares of Series D Preferred Stock
represented by such Depositary Shares and        shares of Common Stock issuable
upon conversion of the Depositary Shares. Each of the Depositary Shares will
represent ownership of 1/100 of a share of Series D Preferred Stock, which will
be deposited with a depositary, and will entitle the holder to such proportion
of all of the rights and preferences of the Series D Preferred Stock represented
thereby.
 
     The annual dividend rate payable with respect to each Depositary Share will
be $       (based on the annual dividend rate for each share of Series D
Preferred Stock of $   .00), will be cumulative from the date of issuance and
will be payable quarterly in arrears, commencing on           , 1997. The
liquidation preference applicable to each Depositary Share (based on the
liquidation preference of each share of Series D Preferred Stock) will be equal
to the sum of (i) the per share initial public offering price of the Depositary
Shares and (ii) 1/100 of the amount of the accrued and unpaid dividends on each
share of Series D Preferred Stock.
 
                                       77
<PAGE>   80
 
     On           , 1999 (the "Mandatory Conversion Date"), unless previously
converted at the option of the holder, each of the outstanding Depositary Shares
will automatically convert into a number of shares of Common Stock of the
Company equal to the Exchange Rate. The Exchange Rate will in no event exceed
one share of Common Stock for each Depositary Share, will be less than one share
of Common Stock where the Current Market Price exceeds the Initial Price and
will vary depending upon whether the Current Market Price exceeds or is lower
than a predetermined "Threshold Price." The "Initial Price" is the public
offering price per share of the Depositary Shares in the Depositary Shares
Offering. The "Current Market Price" means the average closing sale price per
share of Common Stock on the 20 trading days immediately prior to, but not
including, the Mandatory Conversion Date.
 
     At any time after             , 1997 and prior to the Mandatory Conversion
Date, each of the Depositary Shares will be convertible at the option of the
holder thereof into a fraction of a share of Common Stock equivalent to a
conversion price per share equal to the Threshold Price, subject to adjustment
in certain events.
 
TRANSFER AGENT AND REGISTRAR
 
     The Company's Transfer Agent and Registrar is The Boatmen's Trust Company
("Boatmen's Trust"), St. Louis, Missouri.
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
     Upon completion of this Offering and assuming (i) the Underwriters'
over-allotment options are exercised in full and (ii) no exercise of outstanding
warrants and options, the Company will have outstanding           shares of
Common Stock. Of these shares, the           shares sold in this Offering
(          shares if the Underwriters' over-allotment options are exercised in
full) and the 8,704,202 shares sold in the IPO will be freely tradeable without
restriction or further registration under the Securities Act, except for any
shares purchased by "affiliates" of the Company as the term is defined in Rule
144 under the Securities Act ("Affiliates"), which shares will be subject to the
resale limitations of Rule 144. The remaining           shares of Common Stock
("Restricted Shares") held by existing stockholders were issued and sold by the
Company in reliance on exemptions from the registration requirements of the
Securities Act. These shares may be sold in the public market only if registered
or pursuant to an exemption from registration such as those afforded by Rules
144, 144A, 701 and Regulation S under the Securities Act, which are summarized
below.
 
     Upon completion of this Offering, approximately           shares held by
existing stockholders will be eligible for sale pursuant to Rules 144 and 701,
subject to the volume limitations thereof.
 
     Beginning 180 days after the date of this Prospectus, upon the expiration
of public sale restrictions described below (see "Underwriting"), or earlier in
the discretion of the Underwriters, the following approximate additional amounts
of Restricted Shares will become eligible for sale in the public market subject
to the volume limitations under Rule 144 discussed below:           shares
immediately; and           shares from           1997 through           1998.
 
     Options and warrants to purchase 1,304,404 and 409,860 shares of Common
Stock, respectively, were outstanding as of November 15, 1996 and exercisable
within 60 days.
 
     In general, under Rule 144 as currently in effect, an Affiliate of the
Company or other person (or persons whose shares are aggregated) who has
beneficially owned Restricted Shares for at least two years will be entitled to
sell in any three-month period a number of shares that does not exceed the
greater of (i) 1% of the then outstanding shares of the Company's Common Stock
(approximately           shares immediately after the Offering, if the
Underwriters' over-allotment options are exercised in full) or (ii) the average
weekly trading volume of the Company's Common Stock on the Nasdaq National
Market during the four calendar weeks immediately preceding the date on
 
                                       78

which notice of the sale is filed with the Securities and Exchange Commission.
Sales pursuant to Rule 144 are subject to certain requirements relating to
manner of sale, notice and availability of current public information about the
Company. A person (or persons whose shares are aggregated) who is not deemed to
have been an Affiliate of the Company at any time during the 90 days immediately
preceding the sale and who has beneficially owned Restricted Shares for at least
three years is entitled to sell such shares pursuant to Rule 144(k) without
regard to the limitations described above.
 
     Restricted Shares may also be resold (1) 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 and (2) in an off-shore transaction complying with
Rules 903 and 904 of Regulation S under the Securities Act.
 
     An employee of the Company who purchased shares or was awarded options to
purchase shares pursuant to a written compensatory plan or contract meeting the
requirements of Rule 701 under the Securities Act is entitled to rely on the
resale provisions of Rule 701 under the Securities Act, which permits Affiliates
and non-Affiliates to sell their Rule 701 shares without having to comply with
the holding period restrictions of Rule 144, in each case commencing 90 days
after the date of this Prospectus. In addition, non-Affiliates may sell Rule 701
shares without complying with the public information, volume and notice
provisions of Rule 144.
 
     Shares acquired pursuant to the 1993 Stock Option Plan and the 1996
Employee Stock Purchase Plan will be available for sale in the open market upon
the expiration of the public sale restrictions described below (see
"Underwriting"), subject to Rule 144 volume limitations applicable to
Affiliates, except to the extent such shares are subject to vesting restrictions
with the Company.
 
     Upon completion of the Depositary Shares Offering, up to        shares of
Common Stock will be issuable upon conversion of the Depositary Shares. All of
such shares will be issued no later than             , 1999, and shares received
upon conversion will be available for sale in the open market, subject to Rule
144 volume limitations applicable to Affiliates. See "Description of Capital
Stock -- Proposed Offering of Depositary Shares."
 
     Future sales of substantial amounts of Common Stock in the public market
could adversely affect market prices prevailing from time to time. As described
herein, only a limited number of Restricted Shares will be available for sale
shortly after the Offerings because of certain contractual and legal
restrictions on resale. Sales of substantial amounts of Common Stock of the
Company in the public market after the restrictions lapse could adversely affect
the prevailing market price and the ability of the Company to raise equity
capital in the future.

     Under the terms and conditions of the Underwriting Agreement, the U.S.
Underwriters are committed to take and pay for all of the shares offered hereby,
if any are taken.
 
     The U.S. Underwriters propose to offer the shares of Common Stock in part
directly to the public at the public offering price set forth on the cover page
of this Prospectus, and in part to certain securities dealers at such price less
a concession of $     per share (the "U.S. Offering"). The U.S. Underwriters may
allow, and such dealers may reallow, a concession not in excess of $   per share
to certain brokers and dealers. After the shares of Common Stock are released
for sale to the public, the offering price and other selling terms may from time
to time be varied by the representatives.
 
     The Company and the Selling Stockholders have entered into an underwriting
agreement (the "International Underwriting Agreement") with the underwriters of
the International Offering (the "International Underwriters") providing for the
concurrent offer and sale of         shares of Common Stock in an international
offering outside the United States (the "International Offering" and, together
with the U.S. Offering, the "Offerings"). The offering price and aggregate
underwriting discounts and commissions per share for the two Offerings are
identical. The closing of the U.S. Offering is conditioned upon the closing of
the International Offering, and vice versa. The representatives of the
International Underwriters are Goldman Sachs International and Salomon Brothers
International Limited.
 
     Pursuant to an Agreement between the U.S. and International Underwriting
Syndicates (the "Agreement Between") relating to the two Offerings, each of the
U.S. Underwriters named herein has agreed that, as a part of the distribution of
the shares in the U.S. Offering and subject to certain exceptions, it will
offer, sell or deliver the shares of Common Stock, directly or indirectly, only
in the United States of America (including the States thereof and the District
of Columbia), its territories, its possessions and other areas subject to its
jurisdiction (the "United States") and to U.S. persons, which term shall mean,
for purposes of this paragraph: (a) any individual who is a resident of the
United States or (b) any corporation, partnership or other entity organized in
or under the laws of the United States or any political subdivision thereof and
whose office most directly involved with the purchase is located in the United
States. Each of the International Underwriters has agreed pursuant to the
Agreement Between that, as a part of the distribution of the shares offered as a
part
 
                                       80
<PAGE>   83
 
of the International Offering, and subject to certain exceptions, it will (i)
not, directly or indirectly, offer, sell or deliver shares of Common Stock (a)
in the United States or to any U.S. persons or (b) to any person who it believes
intends to reoffer, resell or deliver the shares in the United States or to any
U.S. persons and (ii) cause any dealer to whom it may sell such shares at any
concession to agree to observe a similar restriction.
 
     Pursuant to the Agreement Between, sales may be made between the U.S.
Underwriters and the International Underwriters of such number of shares of
Common Stock as may be mutually agreed. The price of any shares so sold shall be
the public offering price, less an amount not greater than the selling
concession.
 
     The Company has granted the Underwriters an option exercisable for 30
calendar days after the date of this Prospectus to purchase up to an aggregate
of an additional           shares of Common Stock to cover over-allotments, if
any. If the Underwriters exercise their over-allotment option, the Underwriters
have severally agreed, subject to certain conditions, to purchase approximately
the same percentage thereof that the number of the shares to be purchased by
each of them, as shown in the foregoing table, bears to the           shares of
Common Stock offered hereby. The Company has also granted the International
Underwriters a similar option to purchase up to an aggregate of an additional
       shares of Common Stock. The Underwriters may exercise such option only to
cover over-allotments in connection with the sale of the shares offered hereby.
 
     The Company and the Selling Stockholders have agreed not to offer, sell,
contract to sell or otherwise dispose of any shares of Common Stock or any
rights to purchase or other securities convertible into or any securities of the
Company substantially similar to any such shares for a period of 180 days after
the date of this Prospectus without the prior written consent of the
Underwriters, except for (i) the Series D Preferred Stock, Depositary Shares and
shares of Common Stock and the related rights issuable upon conversion of the
Series D Preferred Stock offered in connection with the Depositary Shares
Offering, (ii) shares of Common Stock issued pursuant to existing employee
benefit plans, (iii) shares of Common Stock issued in acquisition transactions,
(iv) upon the conversion or exchange of convertible or exchangeable securities,
or the exercise of any warrants or other rights, outstanding as of the date of
the Underwriting Agreement and (v) in the case of the Selling Stockholders, in
certain non-public transactions in which the acquiror or acquirors of such
shares agree(s) to such restrictions.
 
     This Prospectus may be used by underwriters and dealers in connection with
offers and sales of Common Stock to persons located in the United States.
 
     The Underwriting Agreement provides that the Company and the Selling
Stockholders will indemnify the several Underwriters against certain
liabilities, including certain liabilities under the Securities Act of 1933, or
contribute to payments the Underwriters may be required to make in respect
thereof.
 
     An affiliate of Goldman, Sachs & Co. owns approximately    % of the capital
stock of the Company, on a fully diluted basis as of November 15, 1996. Each of
the representatives may serve as a financial advisor to the Company from time to
time in the future.
 
                     CERTAIN UNITED STATES TAX CONSEQUENCES
                      TO NON-U.S. HOLDERS OF COMMON STOCK
 
     The following is a general discussion of certain U.S. federal income and
estate tax consequences of the ownership and disposition of Common Stock by a
person that, for U.S. federal income tax purposes, is a non-resident alien
individual, a foreign corporation, a foreign partnership or a foreign estate or
trust (a "non-U.S. holder"). This discussion does not consider specific facts
and circumstances that may be relevant to a particular holder's tax position
(including the tax position of certain U.S. expatriates) and does not deal with
U.S. state and local or non-U.S. tax consequences. Furthermore, the following
discussion is based on provisions of the U.S. Internal
 
                                       81
<PAGE>   84
 
Revenue Code of 1986, as amended (the "Code"), and administrative and judicial
interpretations as of the date hereof, all of which are subject to change. Each
prospective holder is urged to consult a tax advisor with respect to the U.S.
federal tax consequences of acquiring, holding and disposing of Common Stock as
well as any tax consequences that may arise under the laws of any U.S. state,
municipality or other tax jurisdiction.
 
DIVIDENDS
 
     Dividends paid to a non-U.S. holder of Common Stock will be subject to
withholding of U.S. federal income tax at a 30% rate or such lower rate as may
be specified by an applicable income tax treaty, unless the dividends are
effectively connected with the conduct of a trade or business within the United
States. Dividends that are effectively connected with such holder's conduct of a
trade or business within the United States and, if an income tax treaty applies,
are attributable to a U.S. permanent establishment of such holder, are subject
to tax at rates applicable to U.S. citizens, resident aliens and domestic U.S.
corporations, and are generally not subject to withholding. Any such effectively
connected dividends received by a foreign corporation may be subject to an
additional "branch profits tax" at a rate of 30% (or such lower rate as may be
specified by an applicable treaty) of its effectively connected earnings and
profits subject to certain adjustments.
 
     Under current United States Treasury regulations, dividends paid to an
address in a foreign country are presumed to be paid to a resident of that
country (unless the payor has knowledge to the contrary) for purposes of the
withholding discussed above and, under the current interpretation of the United
States Treasury regulations, for purposes of determining the applicability of a
tax treaty rate. Under United States Treasury regulations that are proposed to
be effective for distributions after 1997 (the "Proposed Regulations"), however,
a non-U.S. holder of Common Stock who wishes to claim the benefit of an
applicable treaty rate would be required to satisfy applicable certification
requirements. In addition, under the Proposed Regulations, in the case of Common
Stock held by a foreign partnership, (i) the certification requirement would
generally be applied to the partners of the partnership and (ii) the partnership
would be required to provide certain information, including a United States
taxpayer identification number. The Proposed Regulations also provide
look-through rules for tiered partnerships. It is not certain whether, or in
what form, the Proposed Regulations will be adopted as final regulations.
 
     A non-U.S. holder of Common Stock that is eligible for a reduced rate of
U.S. withholding tax pursuant to a tax treaty may obtain a refund of any excess
amounts currently withheld by filing an appropriate claim for refund with the
U.S. Internal Revenue Service.
 
GAIN ON DISPOSITION OF COMMON STOCK
 
     A non-U.S. holder generally will not be subject to U.S. federal income tax
in respect of gain recognized on a disposition of Common Stock unless (i) the
gain is effectively connected with a trade or business of the non-U.S. holder in
the United States, (ii) in the case of a non-U.S. holder who is an individual
and holds the Common Stock as a capital asset, such holder is present in the
United States for 183 or more days in the taxable year of the sale and either
(a) such individual's "tax home" for U.S. federal income tax purposes is in the
United States, or (b) the gain is attributable to an office or other fixed place
of business maintained in the United States by such individual, or (iii) the
Company is or has been a "U.S. real property holding corporation" for federal
income tax purposes and the non-U.S. holder held, directly or indirectly at any
time during the five-year period ending on the date of disposition, more than 5%
of the Common Stock. The Company has not been, is not, and does not anticipate
becoming a "U.S. real property holding corporation" for federal income tax
purposes.

   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.

the responsibility of the Company's management. Our responsibility is to express
an opinion on these consolidated financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing

assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Brooks Fiber

                   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:

        <S>                                                                     <C>

</TABLE>
 
  (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.

     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.

additional funds of $619,000 were received for the issuance of preferred shares.
During 1995 and 1994, the remaining funds under the subscriptions receivable

     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.

these consolidated financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the consolidated financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the consolidated financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
consolidated financial statement presentation. We believe that our audits
provide a reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of City Signal,
Inc. as of December 31, 1995 and 1994, and the results of its operations and its
cash flows for the years then ended in conformity with generally accepted
accounting principles.

                   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>

        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:

3. NOTE PAYABLE AND TRANSACTIONS WITH AFFILIATED COMPANIES
 
     - 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

       outstanding balance was $5,299,364 at December 31, 1994. Interest was
       paid equal to that incurred on the assigned debt instruments. During
       1995, the remaining obligations on those same debt instruments were
       reassigned to the Company and are reported as capital lease obligations
       (see Note 2) and long-term debt (see Note 4).
 
       The related party has not demanded repayment and the outstanding
       indebtedness will be contributed to capital in connection with the sale
       of the Company described in Note 9.
 
     - The Company sold $1,299,353 and $1,425,648 of telecommunication services
       to the affiliated company during the years ended December 31, 1995 and

       $141,000 of management fees to the same affiliated company in each of the
       years ended December 31, 1995 and 1994.
 
     - The Company was billed $312,760 during 1995 for fiber installation
       services to a company owned by one of its officers. The Company also
       subleases warehouse space to the same affiliated company and recognized

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

                          INDEPENDENT AUDITORS' REPORT
 
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.

                   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>   130
 
             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.

     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:

                                    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>   138
 
     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>   139
 
     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>   140
 
     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>   141
 
     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>   142
 
     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.

ITEM 14.  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 made or 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 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 the board of directors by a
majority vote of a quorum consisting of directors who were not parties to such
action, suit or proceeding, by special independent counsel 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 be 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 a person. Insurance
may be purchased on behalf of any person entitled to indemnification by the
corporation against any liability 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 or surviving 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.
 
                                      II-1
<PAGE>   145
 
     The Amended and 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.

     f)  On various dates from November 1, 1996 through November 6, 1996,
warrants to purchase an aggregate of 37,940 shares of the Company's Common Stock
at $22.17 per share were exercised by six investment funds. An aggregate of
12,320 shares was acquired for an aggregate of $273,134 in cash, and an
aggregate of 5,249 shares was acquired in net cashless exercises. The issuance
and sale of the foregoing securities was not registered under the Securities Act
in reliance on the exemption for nonpublic offerings provided by Section 4(2) of
the Securities Act. Each of the holders of such securities are accredited
investors and acquired such shares for investment and subject to restrictions on
transfer which were described in appropriate legends on the certificates
representing such shares of Common Stock.
 
     g)  On various dates from October 8, 1996 through November 8, 1996,
warrants to purchase an aggregate of 1,493,840 shares of the Company's Common
Stock at $11.00 per share and 120 shares at $22.17 per share were exercised by
64 holders thereof. An aggregate of 520,809 shares was acquired for an aggregate
of $5,728,899 in cash, and an aggregate of 593,152 shares was acquired in net
cashless exercises. The issuance and sale of the foregoing securities was not
registered under the Securities Act in reliance on the exemption for nonpublic
offerings provided by Section 4(2) of the Securities Act and Rule 506 of
Regulation D promulgated thereunder. The Company believes that no more than 35
of the holders of such warrants were non-accredited investors and that each
person who was not an accredited investor had such knowledge in financial and
business matters to be capable of evaluating the merits and risks of an
investment in the Company's Common Stock. Each of the holders of such warrants
was furnished the information required by paragraphs (b)(2)(ii)(A) and (C) of
Rule 502 of Regulation D. Each of such holders acquired such securities for
investment and subject to restrictions on transfer which were described in
appropriate legends on the certificates representing such shares of Common
Stock.
 
     h)  On November 15, 1996, Alex. Brown & Sons Incorporated exercised a
warrant to purchase 192,340 shares of the Company's Common Stock at $8.25 per
share, or an aggregate of $1,586,805. The issuance and sale of the foregoing
securities was not registered under the Securities Act in reliance on the
exemption for nonpublic offerings provided by Section 4(2) of the Securities
Act. The holder of such securities is an accredited investor and acquired such
shares for investment and subject to restrictions on transfer which were
described in appropriate legends on the certificate representing such shares of
Common Stock.
 
  2.  SALES OF DEBT SECURITIES
 
     (a)  Pursuant to a Purchase Agreement dated February 16, 1996 with Goldman,
Sachs & Co., Bear, Stearns & Co., Inc. and Salomon Brothers Inc as Purchasers,
the Company has issued and sold to said Purchasers $425,000,000 aggregate
principal amount of 10 7/8% Senior Discount Notes due March 1, 2006 (the
"Private Notes") for aggregate gross cash proceeds to the Company of
approximately $250 million. The issuance of such Notes was not registered under
the Securities Act in reliance on the exemption for nonpublic offerings provided
by Section 4(2) of the Securities Act and Rule 506 of Regulation D promulgated
thereunder. Each of said Purchasers agreed that it would only offer or sell the
Notes in the United States to qualified institutional buyers in reliance on Rule
144A promulgated under the Securities Act and to a limited number of
institutional accredited investors in a manner exempt from the registration
requirements of the Securities Act. On August 15, 1996, the Company completed
the exchange of $425,000,000 aggregate principal amount of its 10 7/8% Senior
Discount Notes (the "Exchange Notes") for all outstanding Private Notes. The
Exchange Notes were registered under the Securities Act pursuant to the
Company's Registration Statement on Form S-4 (File No. 333-06791).
 
     (b)  Pursuant to a Purchase Agreement dated November 1, 1996 with Goldman,
Sachs & Co. and Salomon Brothers Inc as Purchasers, the Company has issued and
sold to said Purchasers $400,000,000 aggregate principal amount of 11 7/8%
Senior Discount Notes due November 1, 2006 for aggregate gross cash proceeds to

registered under the Securities Act in reliance on the exemption for nonpublic
 
                                      II-3

offerings provided by Section 4(2) of the Securities Act and Rule 506 of
Regulation D promulgated thereunder. Each of said Purchasers has agreed that it
will only offer or sell such Notes in the United States to qualified
institutional buyers in reliance on Rule 144A under the Securities Act and to a
limited number of institutional accredited investors in a manner exempt from the
registration requirements of the Securities Act, and outside the United States
to non-U.S. persons in offshore transactions in reliance on Regulation S under
the Securities Act. The subsequent resale of such Notes is also restricted. Such
restrictions on transfer were described in appropriate legends on each of such
Notes which have been issued in fully registered form.

ITEM 17.  UNDERTAKINGS
 
     Insofar as indemnification for liabilities under the Securities Act of 1933
may be permitted to directors, officers and controlling persons of the
registrant pursuant to the provisions described in Item 14, 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
Securities Act of 1933 and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the registrant of expenses incurred or paid by a director, officer or
controlling person of the registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit 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.
 
     The undersigned registrant hereby undertakes that:
 
     (1)  For purposes of determining any liability under the Securities Act of
1933, the information omitted from the form of prospectus filed as part of this
registration statement in reliance upon Rule 430A and contained in the form of
prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h)
under the Securities Act shall be deemed to be part of this registration
statement as of the time it was declared effective.
 
     (2)  For the purpose of determining any liability under the Securities Act
of 1933, each post-effective amendment that contains a form of prospectus shall
be deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.
 
     (3)  To provide to the Underwriters at the closing specified in the
Underwriting Agreement, certificates in such denominations and registered in
such names as required by the Underwriters to permit prompt delivery to each
purchaser.

be embodied in and evidenced by one or more instruments of substantially
similar tenor signed by such Holders in person or by agent duly appointed in
writing; and, except as herein otherwise expressly provided, such action shall
become effective when such instrument or instruments are delivered to the
Trustee and, where it is hereby expressly required, to the Company.  Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments.  Proof of execution of any such instrument or
of a writing appointing any such agent shall be sufficient for any purpose of
this Indenture and (subject to Section 601) conclusive in favor of the Trustee
and the Company, if made in the manner provided in this Section.

         The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof.  Where
such execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his authority.  The fact and date of the execution of any such instrument or
writing, or the authority of the Person executing the same, may also be proved
in any other manner which the Trustee deems sufficient.

         The ownership of Securities shall be proved by the Security Register.

         Any request, demand, authorization, direction, notice, consent, waiver
or other Act of the Holder of any Security shall bind every future Holder of

<PAGE>   43

Holder of every Security issued upon the registration of transfer thereof or in
exchange therefor or in lieu thereof in respect of anything done, omitted or
suffered to be done by the Trustee or the Company in reliance thereon, whether
or not notation of such action is made upon such Security.

         The Company may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities entitled to give, make or
take any request, demand, authorization, direction, notice, consent, waiver or
other action provided or permitted by this Indenture to be given, made or taken
by Holders of Securities, provided that the Company may not set a record date
for, and the provisions of this paragraph shall not apply with respect to, the
giving or making of any notice, declaration, request or direction referred to
in the next paragraph.  If not set by the Company prior to the first
solicitation of a Holder made by any Person in respect of any such matter
referred to in the foregoing sentence, the record date for any such matter
shall be the 30th day (or, if later, the date of the most recent list of
Holders required to be provided pursuant to Section 701) prior to such first
solicitation.  If any record date is set pursuant to this paragraph, the
Holders of Outstanding Securities on such record date, and no other Holders,
shall be entitled to take the relevant action, whether or not such Holders
remain Holders after such record date; provided that no such action shall be
effective hereunder unless taken on or prior to the applicable Expiration Date
by Holders of the requisite principal amount of Outstanding Securities on such
record date.  Nothing in this paragraph shall be construed to prevent the
Company from setting a new record date for any action for which a record date
has previously been set pursuant to this paragraph (whereupon the record date
previously set shall automatically and with no action by any Person be
cancelled and of no effect), and nothing in this paragraph shall be construed
to render ineffective any action taken by Holders of the requisite principal
amount of Outstanding Securities on the date such action is taken. Promptly
after any record date is set pursuant to this paragraph, the Company, at its
own expense, shall cause notice of such record date, the proposed action by
Holders and the applicable Expiration Date to be given to the Trustee in
writing and to each Holder of Securities in the manner set forth in Section
106.

         The Trustee may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities entitled to join in the
giving or making of (i) any Notice of Default, (ii) any declaration of
acceleration referred to in Section 502, (iii) any request to institute
proceedings referred to in Section 507(2) or (iv) any direction referred





                                      -29-
<PAGE>   44

to in Section 512.  If any record date is set pursuant to this paragraph, the
Holders of Outstanding Securities on such record date, and no other Holders,
shall be entitled to join in such notice, declaration, request or direction,
whether or not such Holders remain Holders after such record date; provided
that no such action shall be effective hereunder unless taken on or prior to
the applicable Expiration Date by Holders of the requisite principal amount of
Outstanding Securities on such record date. Nothing in this paragraph shall be
construed to prevent the Trustee from setting a new record date for any action
for which a record date has previously been set pursuant to this paragraph
(whereupon the record date previously set shall automatically and with no
action by any Person be cancelled and of no effect), and nothing in this
paragraph shall be construed to render ineffective any action taken by Holders
of the requisite principal amount of Outstanding Securities on the date such
action is taken. Promptly after any record date is set pursuant to this
paragraph, the Trustee, at the Company's expense, shall cause notice of such
record date, the proposed action by Holders and the applicable Expiration Date
to be given to the Company in writing and to each Holder of Securities in the
manner set forth in Section 106.

         With respect to any record date set pursuant to this Section, the
party hereto which sets such record dates may designate any day as the
"Expiration Date" and from time to time may change the Expiration Date to any
earlier or later day; provided that no such change shall be effective unless
notice of the proposed new Expiration Date is given to the other party hereto
in writing, and to each Holder of Securities in the manner set forth in Section
106, on or prior to the existing Expiration Date. If an Expiration Date is not
designated with respect to any record date set pursuant to this Section, the
party hereto which set such record date shall be deemed to have initially
designated the 180th day after such record date as the Expiration Date with
respect thereto, subject to its right to change the Expiration Date as provided
in this paragraph.  Notwithstanding the foregoing, no Expiration Date shall be
later than the 180th day after the applicable record date.

         Without limiting the foregoing, a Holder entitled hereunder to take
any action hereunder with regard to any particular Security may do so with
regard to all or any part of the principal amount of such Security or by one or
more duly appointed agents each of which may do so pursuant to such appointment
with regard to all or any part of such principal amount.

SECTION 105.  Notices, Etc., to Trustee and Company.

         Any request, demand, authorization, direction, notice, consent, waiver
or Act of Holders or other document provided or permitted by this Indenture to
be made upon, given or furnished to, or filed with,

         (1)  the Trustee by any Holder or by the Company shall be sufficient
    for every purpose hereunder if delivered in writing to the Trustee at its
    Corporate Trust Office, Attention: Corporate Trust Administration, or

         (2)  the Company by the Trustee or by any Holder shall be sufficient
    for every purpose hereunder (unless otherwise herein expressly provided) if
    in writing and mailed, first-class postage prepaid, to the Company
    addressed to it at the address of its principal office specified in the
    first paragraph of this instrument or at any other address previously
    furnished in writing to the Trustee by the Company.


SECTION 106.  Notice to Holders; Waiver.

         Where this Indenture provides for notice to Holders of any event, such
notice shall be sufficiently  given (unless otherwise herein expressly
provided) if in writing and mailed, first-class postage prepaid, to each Holder
affected by such event, at his address as it appears in the Security Register,
not later than the latest date (if any), and not earlier than the earliest date
(if any), prescribed for the giving of such notice.  In any case where notice
to Holders is given by mail, neither the failure to mail such notice, nor any
defect in any notice so mailed, to any particular Holder shall affect the
sufficiency of such notice with respect to other Holders.  Where this Indenture
provides for notice in any manner, such notice may be waived in writing by the
Person entitled to receive such notice, either before or after the event, and
such waiver shall be the equivalent of such notice.  Waivers of notice by
Holders shall be filed with the Trustee, but such filing shall not be a
condition precedent to the validity of any action taken in reliance upon such
waiver.

         In case by reason of the suspension of regular mail service or by
reason of any other cause it shall be impracticable to give such notice by
mail, then such notification as shall be made with the approval of the Trustee
shall constitute a sufficient notification for every purpose hereunder.

         Brooks Fiber Properties, Inc., a corporation duly organized and
existing under the laws of Delaware (herein called the "Company", which term
includes any successor Person under the Indenture hereinafter referred to), for
value received, hereby promises to pay to __________, or registered assigns,
the principal sum of __________ Dollars [if this Security is a Global Security,
then insert:  (which principal amount may from time to time be increased or
decreased to such other principal amounts (which, taken together with the
principal amounts of all other Outstanding Securities, shall not exceed
$400,000,000 in the aggregate at any time) by adjustments made on the records
of the Trustee hereinafter referred to in accordance with the Indenture)]  on
November 1, 2006, and to pay interest thereon from November 1, 2001 or from the
most recent Interest Payment Date to which interest has been paid or duly
provided for, semi-annually on May 1 and November 1 in each year, commencing
May 1, 2002 at the rate of 11 7/8% per annum, until the principal hereof is
paid or made available for payment [If Original Securities, then insert:
provided, however, that if (i) the Company has not filed a registration
statement (the "Exchange Registration Statement") under the Securities Act of
1933, as amended (the "Securities Act"), registering a security substantially
identical to this Security (except that such Security will not contain terms
with respect to the Special Interest payments described below or transfer
restrictions) pursuant to an exchange offer (the "Exchange Offer") (or, in lieu
thereof, a registration statement registering this Security for resale (a
"Resale Registration Statement")) by January 6, 1997, or (ii) the Exchange
Registration Statement relating to the Exchange Offer or, if applicable, the
Resale Registration Statement has not become or been declared effective by
February 5, 1997, or (iii) the Exchange Offer has not been completed within 45
days after the date on which the Exchange Registration Statement has become or
been declared effective initially (if the Exchange Offer is then required to be
made pursuant to the Exchange and Registration Rights Agreement (the "Exchange
and Registration Rights Agreement"), dated as of            , 1996, by and
between the Company, the Purchasers (as defined therein) and the Holders from
time to time of the Securities) or (iv) either the Exchange Registration
Statement or, if applicable, the Resale Registration Statement is filed and
declared effective (except as specifically permitted therein) but shall
thereafter cease to be effective without being succeeded promptly by an
additional registration statement filed and declared effective, in each case

conditions set forth in the Exchange and Registration Rights Agreement (each
such event referred to in clauses (i) through (iv), a "Registration Default"),
then interest will accrue (in addition to the original issue discount and any
stated interest on the Securities) (the "Step-Up") at a rate of 0.5% per annum,
determined daily, on the Accreted Value of the Securities (or, after November
1, 2001 on the principal amount of the Securities), from the period from the
occurrence of the Registration Default until such time (the "Step-Down Date")
as no Registration Default is in effect and, provided, further, that if either
the Exchange Offer has not been consummated or, if applicable, the Resale
Registration Statement has not become or been declared effective, in each case
by March 22, 1997, then the per annum rate of such Special Interest shall
increase (the "Second Step-Up") by an additional 0.5% per annum until such time
(the "Second Step Down Date") as the Company consummates the Exchange Offer or,
if applicable, the Resale Registration Statement becomes or has been declared
effective (after which such interest rate will be restored to its initial
rate).  Interest accruing as a result of the Step-Up or the Second Step-Up is
referred to herein as "Special Interest."  Accrued Special Interest, if any,
shall be paid semi-annually on May 1 and November 1 in each year; and the
amount of accrued Special Interest shall be determined on the basis of the
number of days actually elapsed.  Any accrued and unpaid interest (including
Special Interest) on this Security upon the issuance of an Exchange Security
(as defined in the Indenture) in exchange for this Security shall cease to be
payable to the Holder hereof but such accrued and unpaid interest (including
Special Interest) shall be payable on the next Interest Payment Date for such
Exchange Security to the Holder thereof on the related Regular Record Date.]
The interest so payable, and punctually paid or duly provided for, on any
Interest Payment Date will, as provided in such Indenture, be paid to the
Person in whose name this Security (or one or more Predecessor Securities) is
registered at the close of business on the Regular Record Date for such
interest, which shall be April 15 or October 15 (whether or not a Business
Day), as the case may be, next preceding such Interest Payment Date.  Any such
interest not so punctually paid or duly provided for will forthwith cease to be
payable to the Holder on such Regular Record Date and may either be paid to the
Person in whose name this Security (or one or more Predecessor Securities) is
registered at the close of business on a Special Record Date for the payment of
such Defaulted Interest to be fixed by the Trustee, notice whereof shall be
given to Holders of Securities not less than 10 days prior to such Special
Record Date, or be paid at any time in any other lawful manner not inconsistent
with





                                      -37-

the requirements of any securities exchange on which the Securities may be
listed, and upon such notice as may be required by such exchange, all as more
fully provided in said Indenture.

         The principal of this Security shall not accrue interest (other than
Special Interest, if any) until November 1, 2001, except in the case of a
default in payment of principal and premium, if any, upon acceleration or
redemption, in which case interest shall be payable pursuant to the preceding
paragraph on such overdue principal (and premium, if any), such interest shall
be payable on demand and, if not so paid on demand, such interest shall itself
bear interest at the rate of 11 7/8% per annum (to the extent that the payment
of such interest shall be legally enforceable), and shall accrue from the date
of such demand for payment to the date payment of such interest has been made
or duly provided for, and such interest on unpaid interest shall also be
payable on demand.

         Payment of the principal of (and premium, if any) and interest on this
Security will be made at the corporate trust office of the Trustee and at the
office or agency of the Company maintained for that purpose in the Borough of
Manhattan, The City of New York, New York, and at any other office or agency
maintained by the Company for such purpose, in such coin or currency of the
United States of America as at the time of payment is legal tender for payment
of public and private debts; provided, however, that at the option of the
Company payment of interest may be made by check mailed to the address of the
Person entitled thereto as such address shall appear in the Security Register.

         Reference is hereby made to the further provisions of this Security
set forth on the reverse hereof, which further provisions shall for all
purposes have the same effect as if set forth at this place.

         Unless the certificate of authentication hereon has been executed by
the Trustee referred to on the reverse hereof by manual signature, this
Security shall not be entitled to any benefit under the Indenture or be valid
or obligatory for any purpose.

SECTION 203.  Form of Reverse of Security.

         This Security is one of a duly authorized issue of Securities of the
Company designated as its 11 7/8% Senior Discount Notes due November 1, 2006
(the "Securities") issued under an Indenture, dated as of November 7, 1996
(herein called the "Indenture"), between the Company and The Bank of New York,
as trustee (herein called the "Trustee", which term includes any successor
trustee under the Indenture).  The Securities are limited in aggregate
principal amount to $400,000,000.  Reference is hereby made to the Indenture
and all indentures supplemental thereto for a statement of the respective
rights, limitations of rights, duties and immunities thereunder of the Company,

Securities are, and are to be, authenticated and delivered.

         The Securities are subject to redemption upon not less than 30 nor
more than 60 days' notice by mail to each Holder of Securities to be redeemed
at such Holder's address appearing in the Security Register, in amounts of
$1,000 or an integral multiple of $1,000, at any time on or after
November 1, 2001 and prior to maturity, as a whole or in part, at the election
of the Company, at the following Redemption Prices (expressed as percentages of

of each of the years indicated below:

</TABLE>         

and thereafter at a Redemption Price equal to 100% of the principal amount,
together in the case of any such redemption with accrued interest to the
Redemption Date, but interest installments whose Stated Maturity is on or prior
to such Redemption Date will be payable to the Holders of such Securities, or
one or more Predecessor Securities, of record at the close of business on the
relevant Record Dates referred to on the face hereof, all as provided in the
Indenture.

         The Securities are further subject to redemption prior to November 1,
2001 only in the event that the Company receives net proceeds from any sale of
its Common Stock (other than Disqualified 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 Securities in a
principal amount of up to an aggregate amount equal to 33 1/3% of the original
principal amount of the Securities, provided, however, that Securities in an
amount equal to at least 66 2/3% of the original principal amount of the
Securities remain outstanding after such redemption.  Such redemption must
occur on a Redemption Date within 75 days of any such sale and upon not less
than 30 nor more than 60 days' notice by mail to each Holder of Securities to
be redeemed at such Holder's address appearing in the Security Register, in
amounts of $1,000 or an integral multiple of $1,000 at a Redemption Price of
110% of the Accreted Value of the Securities to but excluding the Redemption
Date.

         The Securities do not have the benefit of any sinking fund
obligations.

         The Indenture provides that, subject to certain conditions, if (i) a
Change of Control (as defined in the Indenture) occurs or (ii) certain Net
Available Proceeds are available to the Company as a result of any Asset
Disposition, the Company shall be required to make an Offer to Purchase for all
or a specified portion of the Securities.

         [If not a Global Security -- In the event of redemption or purchase
pursuant to an Offer to Purchase of this





                                      -40-
<PAGE>   55

Security in part only, a new Security or Securities of like tenor for the
unredeemed or unpurchased portion hereof will be issued in the name of the
Holder hereof upon the cancellation hereof.]

         [If a Global Security insert -- In the event of a deposit or
withdrawal of an interest in this Security (including upon an exchange,
transfer, redemption or repurchase of this Security in part only) effected in
accordance with the Applicable Procedures, the Security Registrar, upon receipt
of notice of such event from the Depositary's custodian for this Security,
shall make an adjustment on its records to reflect an increase or decrease of
the Outstanding principal amount of this Security resulting from such deposit
or withdrawal, as the case may be.]

         If an Event of Default shall occur and be continuing, the principal of
all the Securities may be declared due and payable in the manner and with the
effect provided in the Indenture.

         The Indenture contains provisions for defeasance at any time of (i)
the entire indebtedness of this Security, or (ii) certain restrictive covenants
and Events of Default with respect to this Security, in each case upon
compliance with certain conditions set forth therein.

         Unless the context otherwise requires, the Original Securities (as
defined in the Indenture) and the Exchange Securities (as defined in the
Indenture) shall constitute one series for all purposes under the Indenture,
including without limitation, amendments, waivers, redemptions and Offers to
Purchase.

         The Indenture permits, with certain exceptions as therein provided,
the amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities under the Indenture at
any time by the Company and the Trustee with the consent of the Holders of a
majority in aggregate principal amount of the Securities at the time
Outstanding.  The Indenture also contains provisions permitting the Holders of
specified percentages in aggregate principal amount of the Securities at the
time Outstanding, on behalf of the Holders of all the Securities, to waive
compliance by the Company with certain provisions of the Indenture and certain
past defaults under the Indenture and their consequences.  Any such consent or
waiver by the Holder of this Security shall be conclusive and binding upon such
Holder and upon all future Holders of this Security and of any Security issued
upon the registra-





                                      -41-
<PAGE>   56

tion of transfer hereof or in exchange herefor or in lieu hereof, whether or
not notation of such consent or waiver is made upon this Security.

         No reference herein to the Indenture and no provision of this Security
or of the Indenture shall alter or impair the obligation of the Company, which
is absolute and unconditional, to pay the principal of (and premium, if any)
and interest on this Security at the times, place and rate, and in the coin or
currency, herein prescribed.

         As provided in the Indenture and subject to certain limitations
therein set forth, the transfer of this Security is registrable in the Security
Register, upon surrender of this Security for registration of transfer at the
office or agency of the Company in the Borough of Manhattan, The City of New
York, New York, duly endorsed by, or accompanied by a written instrument of
transfer in form satisfactory to the Company and the Security Registrar duly
executed by, the Holder hereof or his attorney duly authorized in writing, and
thereupon one or more new Securities, of authorized denominations and like
tenor and for the same aggregate principal amount, will be issued to the
designated transferee or transferees.

         The Exchange Securities are issuable only in registered form without
coupons in denominations of $1,000 and any integral multiple thereof, and the
Original Securities are issuable only in registered form without coupons in
denominations of $100,000 principal amount and any integral multiple of $1,000
in excess thereof.  As provided in the Indenture and subject to certain
limitations therein set forth, Securities are exchangeable for a like tenor and
aggregate principal amount of Securities of a different authorized
denomination, as requested by the Holder surrendering the same.

         No service charge shall be made for any such registration of transfer
or exchange, but the Company may require payment of a sum sufficient to cover
any tax or other governmental charge payable in connection therewith.

         Prior to due presentment of this Security for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name this Security is registered as the owner
hereof for all purposes, whether or not this Security be overdue, and neither
the Company, the Trustee nor any such agent shall be affected by notice to the
contrary.

                                               as Trustee


                                By ____________________
                                   Authorized Signatory



                                 ARTICLE THREE

                                 The Securities

SECTION 301.  Title and Terms.

         The aggregate principal amount of Securities which may be
authenticated and delivered under this Indenture is limited to $400,000,000,
except for Securities authenticated and delivered upon registration of transfer
of, or in exchange for, or in lieu of, other Securities pursuant to Section
304, 305, 306, 906 or 1108 or in connection with an Offer to Purchase pursuant
to Section 1013 or 1017.  The Company may issue Exchange Securities from time
to time pursuant to an Exchange Offer or otherwise, in each case pursuant to a
Board Resolution, subject to Section 303, included in an Officers' Certificate
delivered to the Trustee, in authorized denominations in exchange for a like
principal amount of Original Securities.  Upon any such exchange the Original
Securities shall be cancelled in accordance with Section 309 and shall no
longer be deemed Outstanding for any purpose.  In no event shall the aggregate
principal amount of Original Securities and Exchange Securities Outstanding
exceed $400,000,000.

         The Securities shall be known and designated as the "11 7/8% Senior
Discount Notes due November 1,  2006" of the Company.  The Stated Maturity of
the Securities shall be      November 1, 2006.  The Securities shall bear
interest at the rate of 11 7/8 % per annum, from November 1, 2001 or from the
most recent Interest Payment Date thereafter to which interest has been paid or
duly provided for, as the case may be, payable semi-annually on May 1 and
November 1, commencing May 1, 2002, until the principal thereof is paid or made
available for payment; provided, however, with respect to Original Securities,
if there has been a Registration Default, a Step-Up will occur and the Original





                                      -44-
<PAGE>   59

Securities will from then bear Special Interest until the Step-Down Date and,
if either the Exchange Offer has not been consummated or, if applicable, the
Resale Registration Statement has not become or been declared effective, in
each case, by May 21, 1997, a Second Step-Up will occur and the Original
Securities will from then bear Special Interest until the Second Step-Down
Date.  Accrued Special Interest, if any, shall be paid in cash in arrears
semi-annually on     May 1 and November 1 in each year, and the amount of
accrued Special Interest shall be determined on the basis of the number of days
actually elapsed.

         The principal of and premium, if any, and interest on the Securities
shall be payable at the corporate trust office of the Trustee in the Borough of
Manhattan, The City of New York, New York, maintained for such purpose and at
any other office or agency maintained by the Company for such purpose;
provided, however, that at the option of the Company payment of interest may be
made by check mailed to the address of the Person entitled thereto as such
address shall appear in the Security Register.

         The Securities shall be subject to repurchase by the Company pursuant
to an Offer to Purchase as provided in Sections 1013 and 1017 of the Indenture.

         The Securities shall be redeemable as provided in Article Eleven.

         The Securities shall not have the benefit of any sinking fund
obligations.

         The Securities shall be subject to defeasance at the option of the
Company as provided in Article Twelve.

         Unless the context otherwise requires, the Original Securities and the
Exchange Securities shall constitute one series for all purposes under the
Indenture, including without limitation, amendments, waivers, redemptions and
Offers to Purchase.


SECTION 302.  Denominations.

         The Original Securities shall be issuable only in registered form
without coupons and only in denominations of $100,000 and any integral multiple
of $1,000 in excess thereof, and the Exchange Securities shall be issuable only
in registered form without coupons and only in denominations of $1,000 and any
integral multiple thereof.

SECTION 303.  Execution, Authentication, Delivery
               and Dating.

         The Securities shall be executed on behalf of the Company by its
Chairman of the Board, its Vice Chairman of the Board, its President or one of
its Vice Presidents, under its corporate seal reproduced thereon attested by
its Secretary or one of its Assistant Secretaries.  The signature of any of
these officers on the Securities may be manual or facsimile.

         Securities bearing the manual or facsimile signatures of individuals
who were at any time the proper officers of the Company shall bind the Company,
notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Securities or did not
hold such offices at the date of such Securities.

         At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities executed by the Company to
the Trustee for authentication, together with a Company Order for the
authentication and delivery of such Securities; and the Trustee in accordance
with such Company Order shall authenticate and deliver such Securities as in
this Indenture provided and not otherwise.

         At any time and from time to time after the execution and delivery of
this Indenture and after the effectiveness of a Registration Statement under
the Securities Act with respect thereto, the Company may deliver Exchange
Securities executed by the Company to the Trustee for authentication, together
with a Company Order for the authentication and delivery of such Exchange
Securities and a like principal amount of Original Securities for cancellation
in accordance with Section 309 of this Indenture, and the Trustee in accordance
with the Company Order shall authenticate and deliver such Securities.  In
authenticating such Exchange Securities, and accepting the additional
responsibilities under this Indenture in relation to such Securities, the
Trustee shall be entitled to receive, and (subject to Section 601) shall be
fully protected in relying upon, an Opinion of Counsel stating,

         (a)  that such Exchange Securities have been duly and validly issued
    in accordance with the terms of the Indenture, and are entitled to all the
    rights and benefits set forth herein; and





                                      -46-
<PAGE>   61

         (b)  that the issuance of the Exchange Securities in exchange for the
    Original Securities has been effected in compliance with the Securities Act
    of 1933, as amended.

         Each Security shall be dated the date of its authentication.

         No Security shall be entitled to any benefit under this Indenture or
be valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature, and such certificate upon any
Security shall be conclusive evidence, and the only evidence, that such
Security has been duly authenticated and delivered hereunder.


SECTION 304.  Temporary Securities.

         Pending the preparation of definitive Securities, the Company may
execute, and upon Company Order the Trustee shall authenticate and deliver,
temporary Securities which are printed, lithographed, typewritten, mimeographed
or otherwise produced, in any authorized denomination, substantially of the
tenor of the definitive Securities in lieu of which they are issued and with
such appropriate insertions, omissions, substitutions and other variations as
the officers executing such Securities may determine, as evidenced by their
execution of such Securities.

         If temporary Securities are issued, the Company will cause definitive
Securities to be prepared without unreasonable delay.  After the preparation of
definitive Securities, the temporary Securities shall be exchangeable for
definitive Securities upon surrender of the temporary Securities at any office
or agency of the Company designated pursuant to Section 1002, without charge to
the Holder.  Upon surrender for cancellation of any one or more temporary
Securities, the Company shall execute and the Trustee shall authenticate and
deliver in exchange therefor a like tenor and principal amount of definitive
Securities of authorized denominations.  Until so exchanged, the temporary
Securities shall in all respects be entitled to the same benefits under this
Indenture as definitive Securities.


SECTION 305.  Registration, Registration of Transfer and
               Exchange.

         (a)  The Company shall cause to be kept at the Corporate Trust Office
of the Trustee a register (the register





                                      -47-
<PAGE>   62

maintained in such office and in any other office or agency designated pursuant
to Section 1002 being herein sometimes collectively referred to as the
"Security Register") in which, subject to such reasonable regulations as it may
prescribe, the Company shall provide for the registration of Securities and of
transfers of Securities. The Trustee is hereby appointed "Security Registrar"
for the purpose of registering Securities and transfers of Securities as herein
provided.  Such Security Register shall distinguish between Original Securities
and Exchange Securities.

         Subject to the other provisions of this Indenture regarding
restrictions on transfer, upon surrender for registration of transfer of any
Security at an office or agency of the Company designated pursuant to Section
1002 for such purpose in accordance with the terms hereof, the Company shall
execute, and the Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Securities of any
authorized denominations and of a like tenor and aggregate principal amount and
bearing such restrictive legends as may be required by this Indenture.

         At the option of the Holder, and subject to the other provisions of
this Section 305, Securities may be exchanged for other Securities of any
authorized denominations and of a like tenor and aggregate principal amount,
upon surrender of the Securities to be exchanged at such office or agency.
Whenever any Securities are so surrendered for exchange, the Company shall
execute, and the Trustee shall authenticate and deliver, the Securities which
the Holder making the exchange is entitled to receive.

         All Securities issued upon any registration of transfer or exchange of
Securities shall be the valid obligations of the Company, evidencing the same
debt, and (subject to the provisions in the Original Securities regarding the
payment of Special Interest) entitled to the same benefits under this
Indenture, as the Securities surrendered upon such registration of transfer or
exchange.

         Every Security presented or surrendered for registration of transfer
or for exchange shall (if so required by the Company or the Trustee) be duly
endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Company and the Security Registrar duly executed, by the
Holder thereof or his attorney duly authorized in writing.

         No service charge shall be made to the Holder for any registration of
transfer or exchange of Securities, but the





                                      -48-
<PAGE>   63

Company may require payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in connection with any registration of
transfer or exchange of Securities, other than exchanges pursuant to Section
304, 305(d), 906 or 1108 or in accordance with any Offer to Purchase pursuant
to Section 1013 or 1017 not involving any transfer.

         The Company shall not be required (i) to issue, register the transfer
of or exchange any Security during a period beginning at the opening of
business 15 days before the day of the mailing of a notice of redemption of
Securities selected for redemption under Section 1104 and ending at the close
of business on the day of such mailing, or (ii) to register the transfer of or
exchange any Security so selected for redemption in whole or in part, except
the unredeemed portion of any Security being redeemed in part.

         (b)  Certain Transfers and Exchanges.  Notwithstanding any other
provision of this Indenture or the Securities, transfers and exchanges of
Securities and beneficial interests in a Global Security of the kinds specified
in this Section 305(b) shall be made only in accordance with this Section
305(b).

            (i)  Restricted Global Security to Regulation S Global Security.
    If the owner of a beneficial interest in the Restricted Global Security
    wishes at any time to transfer such interest to a Person who wishes to
    acquire the same in the form of a beneficial interest in the Regulation S
    Global Security, such transfer may be effected only in accordance with the
    provisions of this Clause (b)(i) and Clause (b)(vii) below and subject to
    the Applicable Procedures.  Upon receipt by the Trustee, as Security
    Registrar, of (A) an order given by the Depositary or its authorized
    representative directing that a beneficial interest in the Regulation S
    Global Security in a specified principal amount be credited to a specified
    Agent Member's account and that a beneficial interest in the Restricted
    Global Security in an equal principal amount be debited from another
    specified Agent Member's account and (B) a Regulation S Certificate,
    satisfactory to the Trustee and duly executed by the owner of such
    beneficial interest in the Restricted Global Security or his attorney duly
    authorized in writing, then the Trustee, as Security Registrar but subject
    to Clause (b)(vii) below, shall reduce the principal amount of the
    Restricted Global Security and increase the principal amount of the
    Regulation S Global Security by such specified principal amount as provided
    in Section 305(d)(3).





                                      -49-
<PAGE>   64


           (ii)  Regulation S Global Security to Restricted Global Security.
    If the owner of a beneficial interest in the Regulation S Global Security
    wishes at any time to transfer such interest to a Person who wishes to
    acquire the same in the form of a beneficial interest in the Restricted
    Global Security, such transfer may be effected only in accordance with this
    Clause (b)(ii) and subject to the Applicable Procedures.  Upon receipt by
    the Trustee, as Security Registrar, of (A) an order given by the Depositary
    or its authorized representative directing that a beneficial interest in
    the Restricted Global Security in a specified principal amount be credited
    to a specified Agent Member's account and that a beneficial interest in the
    Regulation S Global Security in an equal principal amount be debited from
    another specified Agent Member's account and (B) if such transfer is to
    occur during the Restricted Period, a Restricted Securities Certificate,
    satisfactory to the Trustee and duly executed by the owner of such
    beneficial interest in the Regulation S Global Security or his attorney
    duly authorized in writing, then the Trustee, as Security Registrar, shall
    reduce the principal amount of the Regulation S Global Security and
    increase the principal amount of the Restricted Global Security by such
    specified principal amount as provided in Section 305(d)(3).

              (iii)  Restricted Non-Global Security to Restricted Global
    Security or Regulation S Global Security.  If the Holder of a Restricted
    Security (other than a Global Security) wishes at any time to transfer all
    or any portion of such Restricted Security to a Person who wishes to take
    delivery thereof in the form of a beneficial interest in the Restricted
    Global Security or the Regulation S Global Security, such transfer may be
    effected only in accordance with the provisions of this Clause (b)(iii) and
    Clause (b)(vii) below and subject to the Applicable Procedures.  Upon
    receipt by the Trustee, as Security Registrar, of (A) such Restricted
    Security as provided in Section 305(a) and instructions satisfactory to the
    Trustee directing that a beneficial interest in the Restricted Global
    Security or Regulation S Global Security in a specified principal amount
    not greater than the principal amount of such Security be credited to a
    specified Agent Member's account and (B) a Restricted Securities
    Certificate, if the specified account is to be credited with a beneficial
    interest in the Restricted Global Security, or a Regulation S Certificate,
    if the specified account is to be credited with a beneficial interest in
    the Regulation S Global Security, in either case satisfactory to the
    Trustee and duly executed by





                                      -50-
<PAGE>   65

    such Holder or his attorney duly authorized in writing, then the Trustee,
    as Security Registrar but subject to Clause (b)(vii) below, shall cancel
    such Restricted Security (and issue a new Restricted Security in respect of
    any untransferred portion thereof) as provided in Section 305(a) and
    increase the principal amount of the Restricted Global Security or the
    Regulation S Global Security, as the case may be, by the specified
    principal amount as provided in Section 305(d)(3).

           (iv)  Regulation S Non-Global Security to Restricted Global Security
    or Regulation S Global Security.  If the Holder of a Regulation S Security
    (other than a Global Security) wishes at any time to transfer all or any
    portion of such Regulation S Security to a Person who wishes to acquire the
    same in the form of a beneficial interest in the Restricted Global Security
    or the Regulation S Global Security, such transfer may be effected only in
    accordance with this Clause (b)(iv) and Clause (b)(vii) below and subject
    to the Applicable Procedures.  Upon receipt by the Trustee, as Security
    Registrar, of (A) such Regulation S Security as provided in Section 305(a)
    and instructions satisfactory to the Trustee directing that a beneficial
    interest in the Restricted Global Security or Regulation S Global Security
    in a specified principal amount not greater than the principal amount of
    such Security be credited to a specified Agent Member's account and (B) if
    the transfer is to occur during the Restricted Period and the specified
    account is to be credited with a beneficial interest in the Restricted
    Global Security, a Restricted Securities Certificate satisfactory to the
    Trustee and duly executed by such Holder or his attorney duly authorized in
    writing, then the Trustee, as Security Registrar but subject to Clause
    (b)(vii) below, shall cancel such Regulation S Security (and issue a new
    Regulation S Security in respect of any untransferred portion thereof) as
    provided in Section 305(a) and increase the principal amount of the
    Restricted Global Security or the Regulation S Global Security, as the case
    may be, by the specified principal amount as provided in Section 305(d)(3).

            (v)  Non-Global Security to Non-Global Security.  A Security that
    is not a Global Security may be transferred, in whole or in part, to a
    Person who takes delivery in the form of another Security that is not a
    Global Security as provided in Section 305(a), provided that, if the
    Security to be transferred in whole or in part is a Restricted Security, or
    is a Regulation S Security and the transfer is to occur during the





                                      -51-
<PAGE>   66

    Restricted Period, then the Trustee shall have received (A) a Restricted
    Securities Certificate, satisfactory to the Trustee and duly executed by
    the transferor Holder or his attorney duly authorized in writing, in which
    case the transferee Holder shall take delivery in the form of a Restricted
    Security, or (B) a Regulation S Certificate, satisfactory to the Trustee
    and duly executed by the transferor Holder or his attorney duly authorized
    in writing, in which case the transferee Holder shall take delivery in the
    form of a Regulation S Security (subject in every case to Section 305(c)).

           (vi)  Exchanges between Global Security and Non-Global Security.  A
    beneficial interest in a Global Security may be exchanged for a Security
    that is not a Global Security as provided in Section 305(d), provided that,
    if such interest is a beneficial interest in the Restricted Global
    Security, or if such interest is a beneficial interest in the Regulation S
    Global Security and such exchange is to occur during the Restricted Period,
    then such interest shall be exchanged for a Restricted Security (subject in
    each case to Section 305(c)).  A Security that is not a Global Security may
    be exchanged for a beneficial interest in a Global Security only if (A)
    such exchange occurs in connection with a transfer effected in accordance
    with Clause (b)(iii) or (iv) above or (B) such Security is a Regulation S
    Security and such exchange occurs after the Restricted Period.

          (vii)  Regulation S Global Security to be Held Through Euroclear or
    Cedel during Restricted Period.  The Company shall use its best efforts to
    cause the Depositary to ensure that, until the expiration of the Restricted
    Period, beneficial interests in the Regulation S Global Security may be
    held only in or through accounts maintained at the Depositary by Euroclear
    or Cedel (or by Agent Members acting for the account thereof), and no
    person shall be entitled to effect any transfer or exchange that would
    result in any such interest being held otherwise than in or through such an
    account; provided that this Clause (b)(vii) shall not prohibit any transfer
    or exchange of such an interest in accordance with Clause (b)(ii) or (vi)
    above.

         (c)  Securities Act Legends.  Rule 144A Securities, Other Securities
and their respective Successor Securities shall bear a Restricted Securities
Legend, and the Regulation S Securities and their Successor Securities shall
bear a Regulation S Legend, subject to the following:





                                      -52-
<PAGE>   67

            (i)  subject to the following Clauses of this Section 305(c), a
    Security or any portion thereof which is exchanged, upon transfer or
    otherwise, for a Global Security or any portion thereof shall bear the
    Securities Act Legend borne by such Global Security while represented
    thereby;

           (ii)  subject to the following Clauses of this Section 305(c), a new
    Security which is not a Global Security and is issued in exchange for
    another Security (including a Global Security) or any portion thereof, upon
    transfer or otherwise, shall bear the Securities Act Legend borne by such
    other Security, provided that, if such new Security is required pursuant to
    Section 305(b)(v) or (vi) to be issued in the form of a Restricted
    Security, it shall bear a Restricted Securities Legend and, if such new
    Security is so required to be issued in the form of a Regulation S
    Security, it shall bear a Regulation S Legend;

          (iii)  Registered Securities shall not bear a Securities Act Legend;

           (iv)  at any time after the Securities may be freely transferred
    without registration under the Securities Act or without being subject to
    transfer restrictions pursuant to the Securities Act, a new Security which
    does not bear a Securities Act Legend may be issued in exchange for or in
    lieu of a Security (other than a Global Security) or any portion thereof
    which bears such a legend if the Trustee has received an Unrestricted
    Securities Certificate, satisfactory to the Trustee and duly executed by
    the Holder of such legended Security or his attorney duly authorized in
    writing, and after such date and receipt of such certificate, the Trustee
    shall authenticate and deliver such a new Security in exchange for or in
    lieu of such other Security as provided in this Article Three;

            (v)  a new Security which does not bear a Securities Act Legend may
    be issued in exchange for or in lieu of a Security (other than a Global
    Security) or any portion thereof which bears such a legend if, in the
    Company's judgment, placing such a legend upon such new Security is not
    necessary to ensure compliance with the registration requirements of the
    Securities Act, and the Trustee, at the direction of the Company, shall
    authenticate and deliver such a new Security as provided in this Article
    Three; and





                                      -53-
<PAGE>   68

           (vi)  notwithstanding the foregoing provisions of this Section
    305(c), a Successor Security of a Security that does not bear a particular
    form of Securities Act Legend shall not bear such form of legend unless the
    Company has reasonable cause to believe that such Successor Security is a
    "restricted security" within the meaning of Rule 144, in which case the
    Trustee, at the direction of the Company, shall authenticate and deliver a
    new Security bearing a Restricted Securities Legend in exchange for such
    Successor Security as provided in this Article Three.

         (d)  The provisions of Clauses (1), (2), (3), (4) and (5) below shall
apply only to Global Securities:

            (1)  Each Global Security authenticated under this Indenture shall
    be registered in the name of the Depositary or a nominee thereof and
    delivered to the Depositary or a nominee thereof or custodian therefor, and
    each such Global Security shall constitute a single Security for all
    purposes of this Indenture.

            (2)  Notwithstanding any other provision in this Indenture, no
    Global Security may be exchanged in whole or in part for Securities
    registered, and no transfer of a Global Security in whole or in part may be
    registered, in the name of any Person other than the Depositary or a
    nominee thereof unless (A) the Depositary (i) has notified the Company that
    it is unwilling or unable to continue as Depositary for such Global
    Security and the Company thereupon fails to appoint a successor Depository
    or (ii) has ceased to be a clearing agency registered under the Exchange
    Act, (B) the Company, at its option, notifies the Trustee in writing that
    it elects to cause the issuance of the Securities in definitive registered
    certificated form or (C) 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 Securities evidenced by
    such Global Security.

            (3)  If any Global Security is to be exchanged for other Securities
    or cancelled in whole, it shall be surrendered by or on behalf of the
    Depositary or its nominee to the Trustee, as Security Registrar, for
    exchange or cancellation as provided in this Article Three.  If any Global
    Security is to be exchanged for other Securities or cancelled in part, or
    if another Security is to be exchanged in whole or in part for a beneficial
    interest in any Global Security, then either (i) such Global Security shall
    be so surrendered for





                                      -54-
<PAGE>   69

    exchange or cancellation as provided in this Article Three or (ii) the
    principal amount thereof shall be reduced or increased by an amount equal
    to the portion thereof to be so exchanged or cancelled, or equal to the
    principal amount of such other Security to be so exchanged for a beneficial
    interest therein, as the case may be, by means of an appropriate adjustment
    made on the records of the Trustee, as Security Registrar, whereupon the
    Trustee, in accordance with the Applicable Procedures, shall instruct the
    Depositary or its authorized representative to make a corresponding
    adjustment to its records.  Upon any such surrender or adjustment of a
    Global Security, the Trustee shall, subject to Section 305(d)(2) and as
    otherwise provided in this Article Three, authenticate and deliver any
    Securities issuable in exchange for such Global Security (or any portion
    thereof) to or upon the order of, and registered in such names as may be
    directed by, the Depositary or its authorized representative.  Upon the
    request of the Trustee in connection with the occurrence of any of the
    events specified in the preceding paragraph, the Company shall promptly
    make available to the Trustee a reasonable supply of Securities that are
    not in the form of Global Securities.  The Trustee shall be entitled to
    rely upon any order, direction or request of the Depositary or its
    authorized representative which is given or made pursuant to this Article
    Three if such order, direction or request is given or made in accordance
    with the Applicable Procedures.

            (4)  Every Security authenticated and delivered upon registration
    of transfer of, or in exchange for or in lieu of, a Global Security or any
    portion thereof, whether pursuant to this Section, Section 304, 306, 906,
    1013, 1017 or 1108 or otherwise, shall be authenticated and delivered in
    the form of, and shall be, a Global Security, unless such Security is
    registered in the name of a Person other than the Depositary or a nominee
    thereof.

            (5)  None of the Company, the Trustee, any agent of the Trustee,
    any Paying Agent or the Security Registrar will have any responsibility or
    liability for any aspect of the Depository's records (or the records of the
    participant of such Depository) relating to or payments made on account of
    beneficial ownership interests of a Global Security or for maintaining,
    supervising or reviewing any records of the Depository relating to such
    beneficial ownership interests.

SECTION 306.  Mutilated, Destroyed, Lost and
                       Stolen Securities.

         If any mutilated Security is surrendered to the Trustee, the Company
shall execute and the Trustee shall authenticate and deliver in exchange
therefor a new Security of like tenor and principal amount and bearing a number
not contemporaneously outstanding.

         If there shall be delivered to the Company and the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any
Security and (ii) such security or indemnity as may be required by them to save
each of them and any agent of either of them harmless, then, in the absence of
notice to the Company or the Trustee that such Security has been acquired by a
bona fide purchaser, the Company shall execute and the Trustee shall
authenticate and deliver, in lieu of any such destroyed, lost or stolen
Security, a new Security of like tenor and principal amount and bearing a
number not contemporaneously outstanding.

         In case any such mutilated, destroyed, lost or stolen Security has
become or is about to become due and payable, the Company in its discretion
may, instead of issuing a new Security, pay such Security.

         Upon the issuance of any new Security under this Section, the Company
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

         Every new Security issued pursuant to this Section in lieu of any
destroyed, lost or stolen Security shall constitute an original additional
contractual obligation of the Company, whether or not the destroyed, lost or
stolen Security shall be at any time enforceable by anyone, and shall be
entitled to all the benefits of this Indenture equally and proportionately with
any and all other Securities duly issued hereunder.

         The provisions of this Section are exclusive and shall preclude (to
the extent lawful) all other rights and remedies with respect to the
replacement or payment of mutilated, destroyed, lost or stolen Securities.

SECTION 307.  Payment of Interest; Interest
               Rights Preserved.

         Interest on any Security which is payable, and is punctually paid or
duly provided for, on any Interest Payment Date shall be paid to the Person in
whose name that Security (or one or more Predecessor Securities) is registered
at the close of business on the Regular Record Date for such interest.

         Any interest (including Special Interest) on any Security which is
payable, but is not punctually paid or duly provided for, on any Interest
Payment Date (herein called "Defaulted Interest") shall (a) bear interest at
the rate per annum stated in the form of Security included herein (to the
extent that the payment of such interest shall be legally enforceable), and (b)
forthwith cease to be payable to the Holder on the relevant Regular Record Date
by virtue of having been such Holder, and such Defaulted Interest may be paid
by the Company, at its election in each case, as provided in Clause (1) or (2)
below:

    (1)  The Company may elect to make payment of any Defaulted Interest to the
Persons in whose names the Securities (or their respective Predecessor
Securities) are registered at the close of business on a Special Record Date
for the payment of such Defaulted Interest, which shall be fixed in the
following manner.  The Company shall notify the Trustee in writing of the
amount of Defaulted Interest proposed to be paid on each Security and the date
of the proposed payment, and at the same time the Company shall deposit with
the Trustee an amount of money equal to the aggregate amount proposed to be
paid in respect of such Defaulted Interest or shall make arrangements
satisfactory to the Trustee for such deposit prior to the date of the proposed
payment, such money when deposited to be held in trust for the benefit of the
Persons entitled to such Defaulted Interest as in this Clause provided.
Thereupon the Trustee shall fix a Special Record Date for the payment of such
Defaulted Interest which shall be not more than 15 days and not less than 10
days prior to the date of the proposed payment and not less than 10 days after
the receipt by the Trustee of the notice of the proposed payment.  The Trustee
shall promptly notify the Company of such Special





                                      -57-
<PAGE>   72

Record Date and, in the name and at the expense of the Company, shall cause
notice of the proposed payment of such Defaulted Interest and the Special
Record Date therefor to be mailed, first-class postage prepaid, to each Holder
at his address as it appears in the Security Register, not less than 10 days
prior to such Special Record Date.  Notice of the proposed payment of such
Defaulted Interest and the Special Record Date therefor having been so mailed,
such Defaulted Interest shall be paid to the Persons in whose names the
Securities (or their respective Predecessor Securities) are registered at the
close of business on such Special Record Date and shall no longer be payable
pursuant to the following Clause (2).

    (2)  The Company may make payment of any Defaulted Interest in any other
lawful manner not inconsistent with the requirements of any securities exchange
on which the Securities may be listed, and upon such notice as may be required
by such exchange, if, after notice given by the Company to the Trustee of the
proposed payment pursuant to this Clause, such manner of payment shall be
deemed practicable by the Trustee.

         Subject to the foregoing provisions of this Section, each Security
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any other Security shall carry the rights to interest accrued
and unpaid, and to accrue, which were carried by such other Security.


SECTION 308.  Persons Deemed Owners.

         Prior to due presentment of a Security for registration of transfer,
the Company, the Trustee and any agent of the Company or the Trustee may treat
the Person in whose name such Security is registered as the owner of such
Security for the purpose of receiving payment of principal of and premium, if
any, and (subject to Section 307) interest on such Security and for all other
purposes whatsoever, whether or not such Security be overdue, and neither the
Company, the Trustee nor any agent of the Company or the Trustee shall be
affected by notice to the contrary.

SECTION 309.  Cancellation.

         All Securities surrendered for payment, redemption, registration of
transfer, exchange or pursuant to any Offer to Purchase pursuant to Section
1013 or 1017 shall, if surrendered to any Person other than the Trustee, be
delivered to the Trustee and shall be promptly cancelled by it.  The Company
may at any time deliver to the Trustee for cancellation any Securities
previously authenticated and delivered hereunder which the Company may have
acquired in any manner whatsoever, and all Securities so delivered shall be
promptly cancelled by the Trustee.  No Securities shall be authenticated in
lieu of or in exchange for any Securities cancelled as provided in this
Section, except as expressly permitted by this Indenture.  All cancelled
Securities held by the Trustee shall be disposed of in accordance with its
standard procedures or as directed by a Company Order; provided, however, that
the Trustee shall not be required to destroy such Securities.


SECTION 310.  Computation of Interest.

         Interest on the Securities shall be computed on the basis of a 360-day
year of twelve 30-day months, provided, however, that Special Interest on
Original Securities shall be computed on the basis of a 365- or 366-day year,
as the case may be, and the number of days actually elapsed.


SECTION 311.  CUSIP and ISIN Numbers.

         The Company in issuing Securities may use "CUSIP" and "ISIN" numbers
(if then generally in use) in addition to serial numbers; if so, the Trustee
shall use such "CUSIP" and "ISIN" numbers in addition to serial numbers in
notices of redemption and repurchase as a convenience to Holders; provided that
any such notice may state that no representation is made as to the correctness
of such CUSIP and ISIN numbers either as printed on the Securities or as
contained in any notice of a redemption or repurchase and that reliance may be
placed only on the serial or other identification numbers printed on the
Securities, and any such redemption or repurchase shall not be affected by any
defect in or omission of such CUSIP and ISIN numbers.

         Trustee for cancellation;

         and the Company, in the case of (A) above, has deposited or caused to
         be deposited with the Trustee as trust funds in trust for the purpose
         an amount sufficient to pay and discharge the entire indebtedness on
         such Securities not theretofore delivered to the Trustee for
         cancellation, for principal of and premium, if any, and interest to

determine, to the Persons entitled thereto, of the principal (and premium, if
any) and interest for whose payment such money has been deposited with the

SECTION 502.  Acceleration of Maturity; Rescission
               and Annulment.

         If an Event of Default (other than an Event of Default specified in
Section 501(8) or (9)) occurs and is





                                      -63-
<PAGE>   78

continuing, then and in every such case the Trustee or the Holders of not less
than 25% in principal amount of the Outstanding Securities may declare the
Default Amount of all the Securities to be due and payable immediately, by a
notice in writing to the Company (and to the Trustee if given by Holders), and
upon any such declaration such Default Amount and any accrued interest shall
become immediately due and payable.  If an Event of Default specified in
Section 501(8) or (9) occurs, the Default Amount of and any accrued interest on
the Securities then Outstanding shall ipso facto become immediately due and
payable without any declaration or other Act on the part of the Trustee or any
Holder.

         The "Default Amount" in respect of any particular Security as of any
particular date of acceleration shall equal the Accreted Value of the Security
on such date.

         At any time after such a declaration of acceleration has been made and
before a judgment or decree for payment of the money due based on acceleration
has been obtained by the Trustee as hereinafter in this Article provided, the
Holders of a majority in principal amount of the Outstanding Securities, by
written notice to the Company and the Trustee, may rescind and annul such
declaration and its consequences if:

         (1)  the Company has paid or deposited with the Trustee a sum
    sufficient to pay

              (A)  all overdue interest on all Securities,

              (B)  the principal of (and premium, if any, on) any Securities
         which have become due otherwise than by such declaration of
         acceleration (including any Securities required to have been purchased
         on the Purchase Date pursuant to an Offer to Purchase made by the
         Company) and interest thereon at the rate borne by the Securities,

              (C)  to the extent that payment of such interest is lawful,
         interest upon overdue interest at the rate borne by the Securities,
         and

              (D)  all sums paid or advanced by the Trustee hereunder and the
         reasonable compensation, expenses, disbursements and advances of the
         Trustee, its agents and counsel;

    and





                                      -64-
<PAGE>   79

         (2)  all Events of Default, other than the non-payment of the
    principal of Securities which have become due solely by such declaration of
    acceleration, have been cured or waived as provided in Section 513.

No such rescission shall affect any subsequent default or impair any right
consequent thereon.


SECTION 503.  Collection of Indebtedness and Suits
               for Enforcement by Trustee.

         The Company covenants that if

         (1)  default is made in the payment of any interest on any Security
    when such interest becomes due and payable and such default continues for a
    period of 30 days, or

         (2)  default is made in the payment of the principal of (or premium,
    if any, on) any Security at the Maturity thereof or, with respect to any
    Security required to have been purchased pursuant to an Offer to Purchase
    made by the Company, at the Purchase Date thereof,

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Securities, the whole amount then due and payable on such
Securities for principal (and premium, if any) and interest, and, to the extent
that payment of such interest shall be legally enforceable, interest on any
overdue principal (and premium, if any) and on any overdue interest, at the
rate provided by the Securities, and, in addition thereto, such further amount
as shall be sufficient to cover the costs and expenses of collection, including
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel.

         If the Company fails to pay such amounts forthwith upon such demand,
the Trustee, in its own name and as trustee of an express trust, may institute
a judicial proceeding for the collection of the sums so due and unpaid, may
prosecute such proceeding to judgment or final decree, and may enforce the same
against the Company or any other obligor upon the Securities and collect the
moneys adjudged or decreed to be payable in the manner provided by law out of
the property of the Company or any other obligor upon the Securities, wherever
situated.

         If an Event of Default occurs and is continuing, the Trustee may in
its discretion proceed to protect and enforce its rights and the rights of the
Holders by such appropriate judicial proceedings as the Trustee shall deem most





                                      -65-
<PAGE>   80

effective to protect and enforce any such rights, whether for the specific
enforcement of any covenant or agreement in this Indenture or in aid of the
exercise of any power granted herein, or to enforce any other proper remedy.


SECTION 504.  Trustee May File Proofs of Claim.

         In case of any judicial proceeding relative to the Company (or any
other obligor upon the Securities), its property or its creditors, the Trustee
shall be entitled and empowered, by intervention in such proceeding or
otherwise, to take any and all actions authorized under the Trust Indenture Act
in order to have claims of the Holders and the Trustee allowed in any such
proceeding.  In particular, the Trustee shall be authorized to collect and
receive any moneys, securities or other property payable or deliverable upon
the exchange of the Securities or upon any such claims and to distribute the
same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator
or other similar official in any such judicial proceeding is hereby authorized
by each Holder to make such payments to the Trustee and, in the event that the
Trustee shall consent to the making of such payments directly to the Holders,
to pay to the Trustee any amount due it for the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel,
and any other amounts due the Trustee under Section 607.

         No provision of this Indenture shall be deemed to authorize the
Trustee to authorize or consent to or accept or adopt on behalf of any Holder
any plan of reorganization, arrangement, adjustment or composition affecting
the Securities or the rights of any Holder thereof or to authorize the Trustee
to vote in respect of the claim of any Holder in any such proceeding; provided,
however, that the Trustee may, on behalf of the Holders, vote for the election
of a trustee in bankruptcy or similar official and be a member of a creditors
or other similar committee.


SECTION 505.  Trustee May Enforce Claims Without
            Possession of Securities.

         All rights of action and claims under this Indenture or the Securities
may be prosecuted and enforced by the Trustee without the possession of any of
the Securities or the production thereof in any proceeding relating thereto,
and any such proceeding instituted by the Trustee shall be brought in its own
name as trustee of an express trust, and any recovery of judgment shall, after
provision for the





                                      -66-
<PAGE>   81

payment of the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel, be for the ratable benefit of the Holders
of the Securities in respect of which such judgment has been recovered.


SECTION 506.  Application of Money Collected.

         Any money collected by the Trustee pursuant to this Article shall be
applied in the following order, at the date or dates fixed by the Trustee and,
in case of the distribution of such money on account of principal (or premium,
if any) or interest, upon presentation of the Securities and the notation
thereon of the payment if only partially paid and upon surrender thereof if
fully paid:

         FIRST:  To the payment of all amounts due the Trustee under 
    Section 607; and

         SECOND:  To the payment of the amounts then due and unpaid for
    principal of (and premium, if any) and interest on the Securities in
    respect of which or for the benefit of which such money has been collected,
    ratably, without preference or priority of any kind, according to the
    amounts due and payable on such Securities for principal (and premium, if
    any) and interest, respectively.


SECTION 507.  Limitation on Suits.

         No Holder of any Security shall have any right to institute any
proceeding, judicial or otherwise, with respect to this Indenture, or for the
appointment of a receiver or trustee, or for any other remedy hereunder, unless

         (1)  such Holder has previously given written notice to the Trustee of
    a continuing Event of Default;

         (2)  the Holders of not less than 25% in aggregate principal amount of
    the Outstanding Securities shall have made written request to the Trustee
    to institute proceedings in respect of such Event of Default in its own
    name as Trustee hereunder;

         (3)  such Holder or Holders have offered and, if requested, provided
    to the Trustee reasonable indemnity against the costs, expenses and
    liabilities to be incurred in compliance with such request;





                                      -67-
<PAGE>   82

         (4)  the Trustee for 60 days after its receipt of such notice, request
    and offer and, if requested, provision of indemnity has failed to institute
    any such proceeding; and

         (5)  no direction inconsistent with such written request has been
    given to the Trustee during such 60-day period by the Holders of a majority
    in principal amount of the Outstanding Securities;

it being understood and intended that no one or more Holders shall have any
right in any manner whatever by virtue of, or by availing of, any provision of
this Indenture to affect, disturb or prejudice the rights of any other Holders,
or to obtain or to seek to obtain priority or preference over any other Holders
or to enforce any right under this Indenture, except in the manner herein
provided and for the equal and ratable benefit of all the Holders.


SECTION 508.  Unconditional Right of Holders
               to Receive Principal, Premium and Interest.

         Notwithstanding any other provision in this Indenture, the Holder of
any Security shall have the right, which is absolute and unconditional, to
receive payment of the principal of (and premium, if any) and (subject to
Section 307) interest on such Security on the respective Stated Maturities
expressed in such Security (or, in the case of redemption, on the Redemption
Date or, in the case of an Offer to Purchase made by the Company and required
to be accepted as to such Security, on the Purchase Date) and to institute suit
for the enforcement of any such payment, and such rights shall not be impaired
without the consent of such Holder.


SECTION 509.  Restoration of Rights and Remedies.

         If the Trustee or any Holder has instituted any proceeding to enforce
any right or remedy under this Indenture and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to
the Trustee or to such Holder, then and in every such case, subject to any
determination in such proceeding, the Company, the Trustee and the Holders
shall be restored severally and respectively to their former positions
hereunder and thereafter all rights and remedies of the Trustee and the Holders
shall continue as though no such proceeding had been instituted.

SECTION 510.  Rights and Remedies Cumulative.

         Except as otherwise provided with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities in the last
paragraph of Section 306, no right or remedy herein conferred upon or reserved
to the Trustee or to the Holders is intended to be exclusive of any other right
or remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise.  The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent
the concurrent assertion or employment of any other appropriate right or
remedy.


SECTION 511.  Delay or Omission Not Waiver.

         No delay or omission of the Trustee or of any Holder of any Security
to exercise any right or remedy accruing upon any Event of Default shall impair
any such right or remedy or constitute a waiver of any such Event of Default or
an acquiescence therein.  Every right and remedy given by this Article or by
law to the Trustee or to the Holders may be exercised from time to time, and as
often as may be deemed expedient, by the Trustee or by the Holders, as the case
may be.


SECTION 512.  Control by Holders.

         The Holders of a majority in principal amount of the Outstanding
Securities shall 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, provided that

         (1)  such direction shall not be in conflict with any rule of law or
    with this Indenture or expose the Trustee to personal liability (as
    determined in the sole discretion of the Trustee), and

         (2)  the Trustee may take any other action deemed proper by the
    Trustee which is not inconsistent with such direction.

SECTION 513.  Waiver of Past Defaults.

         The Holders of not less than a majority in aggregate principal amount
of the Outstanding Securities may on behalf of the Holders of all the
Securities by written notice to the Trustee waive any past default hereunder
and its consequences, except a default

         (1)  in the payment of the principal of (or premium, if any) or
    interest on any Security (including any Security which is required to have
    been purchased pursuant to an Offer to Purchase which has been made by the
    Company), or

         (2)  in respect of a covenant or provision hereof which under Article
    Nine cannot be modified or amended without the consent of the Holder of
    each Outstanding Security affected or

         (3)  arising from failure to purchase any Security tendered pursuant
    to Sections 1013 and 1017 of this Indenture.

         Upon any such waiver, such default shall cease to exist, and any Event
of Default arising therefrom shall be deemed to have been cured, for every
purpose of this Indenture; but no such waiver shall extend to any subsequent or
other default or impair any right consequent thereon.


SECTION 514.  Undertaking for Costs.

         In any suit for the enforcement of any right or remedy under this
Indenture, or in any suit against the Trustee for any action taken or omitted
by it as Trustee, a court may require any party litigant in such suit to file
an undertaking to pay the costs of such suit, and may assess costs against any
such party litigant, in the manner and to the extent provided in the Trust
Indenture Act; provided, that neither this Section nor the Trust Indenture Act
shall be deemed to authorize any court to require such an undertaking or to
make such an assessment in any suit instituted by the Company; further
provided, that the provisions of this Section 514 shall not apply to any suit
instituted by the Trustee, to any suit instituted by any Holder or group of
Holders holding more than 10% in aggregate principal amount of the Outstanding
Securities, or to any suit instituted by any Holder for the enforcement of the
payment of the principal of, or premium, if any, or interest on any Security on
or after the respective due dates expressed in such Security.

SECTION 515.  Waiver of Stay or Extension Laws.

         The Company covenants (to the extent that it may lawfully do so) that
it will not at any time insist upon, or plead, or in any manner whatsoever
claim or take the benefit or advantage of, any stay or extension law wherever
enacted, now or at any time hereafter in force, which may affect the covenants
or the performance of this Indenture; and the Company (to the extent that it
may lawfully do so) hereby expressly waives all benefit or advantage of any
such law and covenants that it will not hinder, delay or impede the execution
of any power herein granted to the Trustee, but will suffer and permit the
execution of every such power as though no such law had been enacted.



                                  ARTICLE SIX

                                  The Trustee

SECTION 601.  Certain Duties and Responsibilities.

         (a)  Except during the continuance of an Event of Default,

         (1)  the Trustee undertakes to perform such duties and only such
    duties as are specifically set forth in this Indenture, and no implied
    covenants or obligations shall be read into this Indenture against the
    Trustee; and

         (2)  in the absence of bad faith on its part, the Trustee may
    conclusively rely, as to the truth of the statements and the correctness of
    the opinions expressed therein, upon certificates or opinions furnished to
    the Trustee and conforming to the requirements of this Indenture; but in
    the case of any such certificates or opinions which by any provision hereof
    are specifically required to be furnished to the Trustee, the Trustee shall
    be under a duty to examine the same to determine whether or not they
    conform to the requirements of this Indenture.

         (b)  In case an Event of Default has occurred and is continuing, the
Trustee shall exercise such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in their exercise, as a
prudent man would exercise or use under the circumstances in the conduct of his
own affairs.





                                      -71-
<PAGE>   86

         (c)  No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act, or its own willful misconduct, except that

         (1)  this Subsection shall not be construed to limit the effect of
    Subsection (a) of this Section;

         (2)  the Trustee shall not be liable for any error of judgment made in
    good faith by a Responsible Officer, unless it shall be proved that the
    Trustee was negligent in ascertaining the pertinent facts;

         (3)  the Trustee shall not be liable with respect to any action taken
    or omitted to be taken by it in good faith in accordance with the direction
    of the Holders of a majority in principal amount of the Outstanding
    Securities relating to the time, method and place of conducting any
    proceeding for any remedy available to the Trustee, or exercising any trust
    or power conferred upon the Trustee, under this Indenture; and

         (4)  no provision of this Indenture shall require the Trustee to
    expend or risk its own funds or otherwise incur any financial liability in
    the performance of any of its duties hereunder, or in the exercise of any
    of its rights or powers, if it shall have reasonable grounds for believing
    that repayment of such funds or adequate indemnity against such risk or
    liability is not reasonably assured to it.

         (d)  Whether or not therein expressly so provided, every provision of
this Indenture relating to the conduct or affecting the liability of or
affording protection to the Trustee shall be subject to the provisions of this
Section.


SECTION 602.  Notice of Defaults.

         The Trustee shall give the Holders notice of any default hereunder
known to the Trustee as and to the extent provided by the Trust Indenture Act;
provided, however, that in the case of any default of the character specified
in Section 501(5), no such notice to Holders shall be given until at least 30
days after the occurrence thereof.  For the purpose of this Section, the term
"default" means any event which is, or after notice or lapse of time or both
would become, an Event of Default.

SECTION 603.  Certain Rights of Trustee.

         Subject to the provisions of Section 601:

         (a)  the Trustee may rely and shall be protected in acting or
    refraining from acting upon any resolution, certificate, statement,
    instrument, opinion, report, notice, request, direction, consent, order,
    bond, debenture, note, other evidence of indebtedness or other paper or

    bad faith on its part, rely upon an Officers' Certificate;

         (d)  the Trustee may consult with counsel of its selection and the

         (e)  the Trustee shall be under no obligation to exercise any of the
    rights or powers vested in it by this Indenture at the request or direction
    of any of the Holders pursuant to this Indenture, unless such Holders shall
    have offered to the Trustee reasonable security or indemnity against the
    costs, expenses and liabilities which might be incurred by it in compliance
    with such request or direction reasonably satisfactory to the Trustee;

         (f)  the Trustee shall not be bound to make any investigation into the
    facts or matters stated in any resolution, certificate, statement,
    instrument, opinion, report, notice, request, direction, consent, order,
    bond, debenture, note, other evidence of indebtedness or other paper or
    document, but the Trustee, in its discretion, may make such further inquiry
    or investigation into such





                                      -73-
<PAGE>   88

    facts or matters as it may see fit, and, if the Trustee shall determine to
    make such further inquiry or investigation, it shall be entitled to examine
    the books, records and premises of the Company, personally or by agent or
    attorney;

         (g)  the Trustee may execute any of the trusts or powers hereunder or
    perform any duties hereunder either directly or by or through agents or
    attorneys and the Trustee shall not be responsible for any misconduct or
    negligence on the part of any agent or attorney appointed with due care by
    it hereunder;

         (h)  the Trustee shall not be liable with respect to any action taken,
    suffered or omitted to be taken by it in accordance with the direction of
    Holders of Outstanding Securities as provided in Sections 502, 512 and 513
    hereof; and

         (i)  for all purposes under this Indenture, the Trustee shall not be
    deemed to have notice of any Event of Default unless a Responsible Officer
    of the Trustee has actual knowledge thereof or unless written notice of any
    event which is in fact such a default is received by the Trustee at the
    Corporate Trust Office of the Trustee, and such notice references the
    Securities and this Indenture.


SECTION 604.  Not Responsible for Recitals
               or Issuance of Securities.

         The recitals contained herein and in the Securities, except the
Trustee's certificates of authentication, shall be taken as the statements of
the Company, and the Trustee assumes no responsibility for their correctness.
The Trustee makes no representations as to the validity or sufficiency of this
Indenture or of the Securities.  The Trustee shall not be accountable for the
use or application by the Company of Securities or the proceeds thereof.


SECTION 605.  May Hold Securities.

         The Trustee, any Paying Agent, any Security Registrar or any other
agent of the Company, in its individual or any other capacity, may become the
owner or pledgee of Securities and, subject to Sections 608 and 613, may
otherwise deal with the Company with the same rights it would have if it were
not Trustee, Paying Agent, Security Registrar or such other agent.





                                      -74-
<PAGE>   89


SECTION 606.  Money Held in Trust.

         Money held by the Trustee in trust hereunder need not be segregated
from other funds except to the extent required by law.  The Trustee shall be
under no liability for interest on any money received by it hereunder except as
otherwise agreed with the Company.


SECTION 607.  Compensation and Reimbursement.

         The Company agrees

         (1)  to pay to the Trustee from time to time reasonable compensation
    for all services rendered by it hereunder (which compensation shall not be
    limited by any provision of law in regard to the compensation of a trustee
    of an express trust);

         (2)  except as otherwise expressly provided herein, to reimburse the
    Trustee upon its request for all reasonable expenses, disbursements and
    advances incurred or made by the Trustee in accordance with any provision
    of this Indenture (including the reasonable compensation and the expenses
    and disbursements of its agents and counsel), except any such expense,
    disbursement or advance as may be attributable to its negligence or bad
    faith; and

         (3)  to indemnify the Trustee for, and to hold it harmless against,
    any loss, liability or expense incurred without negligence or bad faith on
    its part, arising out of or in connection with the acceptance or
    administration of this trust, including the costs and expenses of enforcing
    this Indenture against the Company (including, without limitation, this
    Section 607) and of defending itself against any claim (whether asserted by
    any Holder or the Company) or liability in connection with the exercise or
    performance of any of its powers or duties hereunder.  The provisions of
    this Section 607 shall survive any termination of this Indenture and the
    resignation or removal of the Trustee.

         As security for the performance of the obligations of the Company
under this Section 607, the Trustee shall have a lien prior to the Securities
upon all property and funds held or collected by the Trustee, except funds held
in trust for the payment of principal of (and premium, if any) or interest on
particular Securities.  The Trustee's right to receive payment of any amounts
due under this Section 607 shall not be subordinate to any other liability or





                                      -75-
<PAGE>   90

indebtedness of the Company (even though the Securities may be so
subordinated).

         When the Trustee incurs expenses or renders services in connection
with an Event of Default specified in Section 501(8) or Section 501(9), the
expenses (including the reasonable charges and expenses of its counsel) and the
compensation for the services are intended to constitute expenses of
administration under any applicable Federal or state bankruptcy, insolvency or
other similar law.

         The provisions of this Section shall survive the termination of this
Indenture.

SECTION 608.  Disqualification; Conflicting Interests.

         If the Trustee has or shall acquire a conflicting interest within the
meaning of the Trust Indenture Act, the Trustee shall either eliminate such
interest or resign, to the extent and in the manner provided by, and subject to
the provisions of, the Trust Indenture Act and this Indenture.


SECTION 609.  Corporate Trustee Required; Eligibility.

         There shall at all times be a Trustee hereunder which shall be a
Person that is eligible pursuant to the Trust Indenture Act to act as such and
has a combined capital and surplus of at least $50,000,000 and its Corporate
Trust Office in the Borough of Manhattan, The City of New York, New York.  If
such Person publishes reports of condition at least annually, pursuant to law
or to the requirements of a Federal, State, Territorial or District of Columbia
supervising or examining authority, then for the purposes of this Section, the
combined capital and surplus of such Person shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so
published.  If at any time the Trustee shall cease to be eligible in accordance
with the provisions of this Section, it shall resign immediately in the manner
and with the effect hereinafter specified in this Article.


SECTION 610.  Resignation and Removal; Appointment
               of Successor.

         (a)  No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee under Section 611, at which
time





                                      -76-
<PAGE>   91

the retiring Trustee shall be fully discharged from its obligations hereunder.

         (b)  The Trustee may resign at any time by giving written notice
thereof to the Company.  If an instrument of acceptance by a successor Trustee
shall not have been delivered to the Trustee within 30 days after the giving of
such notice of resignation, the resigning Trustee may petition any court of
competent jurisdiction for the appointment of a successor Trustee.

         (c)  The Trustee may be removed at any time by Act of the Holders of a
majority in principal amount of the Outstanding Securities, delivered to the
Trustee and to the Company.

         (d)  If at any time:

         (1)  the Trustee shall fail to comply with Section 608 after written
    request therefor by the Company or by any Holder who has been a bona fide
    Holder of a Security for at least six months, or

         (2)  the Trustee shall cease to be eligible under Section 609 and
    shall fail to resign after written request therefor by the Company or by
    any such Holder, or

         (3)  the Trustee shall become incapable of acting or shall be adjudged
    a bankrupt or insolvent or a receiver of the Trustee or of its property
    shall be appointed or any public officer shall take charge or control of
    the Trustee or of its property or affairs for the purpose of
    rehabilitation, conservation or liquidation,

then, in any such case, (i) the Company by a Board Resolution may remove the
Trustee, or (ii) subject to Section 514, any Holder who has been a bona fide
Holder of a Security for at least six months may, on behalf of himself and all
others similarly situated, petition any court of competent jurisdiction for the
removal of the Trustee and the appointment of a successor Trustee.

         (e)  If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause, the
Company, by a Board Resolution, shall promptly appoint a successor Trustee.
If, within one year after such resignation, removal or incapability, or the
occurrence of such vacancy, a successor Trustee shall be appointed by Act of
the Holders of a majority in principal amount of the Outstanding Securities
delivered to the Company and the retiring Trustee, the successor Trustee





                                      -77-
<PAGE>   92

so appointed shall, forthwith upon its acceptance of such appointment, become
the successor Trustee and supersede the successor Trustee appointed by the
Company.  If no successor Trustee shall have been so appointed by the Company
or the Holders and accepted appointment in the manner hereinafter provided, any
Holder who has been a bona fide Holder of a Security for at least six months
may, on behalf of himself and all others similarly situated, petition any court
of competent jurisdiction for the appointment of a successor Trustee.

         (f)  The Company shall give notice of each resignation and each
removal of the Trustee and each appointment of a successor Trustee to all
Holders in the manner provided in Section 106.  Each notice shall include the
name of the successor Trustee and the address of its Corporate Trust Office.


SECTION 611.  Acceptance of Appointment by Successor.

         Every successor Trustee appointed hereunder shall execute, acknowledge
and deliver to the Company and to the retiring Trustee an instrument accepting
such appointment, and thereupon the resignation or removal of the retiring
Trustee shall become effective and such successor Trustee, without any further
act, deed or conveyance, shall become vested with all the rights, powers,
trusts and duties of the retiring Trustee; but, on request of the Company or
the successor Trustee, such retiring Trustee shall, upon payment of all sums
owing to the Trustee under Section 607, execute and deliver an instrument
transferring to such successor Trustee all the rights, powers and trusts of the
retiring Trustee and shall duly assign, transfer and deliver to such successor
Trustee all property and money held by such retiring Trustee hereunder.  Upon
request of any such successor Trustee, the Company shall execute any and all
instruments for more fully and certainly vesting in and confirming to such
successor Trustee all such rights, powers and trusts.

         No successor Trustee shall accept its appointment unless at the time
of such acceptance such successor Trustee shall be qualified and eligible under
this Article.


SECTION 612.  Merger, Conversion, Consolidation
               or Succession to Business.

         Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any





                                      -78-
<PAGE>   93

corporation resulting from any merger, conversion or consolidation to which the
Trustee shall be a party, or any corporation succeeding to all or substantially
all the corporate trust business of the Trustee, shall be the successor of the
Trustee hereunder, provided that such corporation shall be otherwise qualified
and eligible under this Article, without the execution or filing of any paper
or any further act on the part of any of the parties hereto.  In case any
Securities shall have been authenticated, but not delivered, by the Trustee
then in office, any successor by merger, conversion or consolidation to such
authenticating Trustee may adopt such authentication and deliver the Securities
so authenticated with the same effect as if such successor Trustee had itself
authenticated such Securities.


SECTION 613.  Preferential Collection
               of Claims Against Company.

         If and when the Trustee shall be or become a creditor of the Company
(or any other obligor upon the Securities), the Trustee shall be subject to the
provisions of the Trust Indenture Act regarding the collection of claims
against the Company (or any such other obligor).



SECTION 614.  Appointment of Authenticating Agent.

         The Trustee may appoint an Authenticating Agent or Agents with respect
to the Securities which shall be authorized to act on behalf of the Trustee to
authenticate Securities issued upon original issue and upon exchange,
registration of transfer or partial redemption thereof or pursuant to Section
306, and Securities so authenticated shall be entitled to the benefits of this
Indenture and shall be valid and obligatory for all purposes as if
authenticated by the Trustee hereunder. Wherever reference is made in this
Indenture to the authentication and delivery of Securities by the Trustee or
the Trustee's certificate of authentication, such reference shall be deemed to
include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent. Each Authenticating Agent shall be
acceptable to the Company and shall at all times be a corporation organized and
doing business under the laws of the United States of America, any State
thereof or the District of Columbia, authorized under such laws to act as
Authenticating Agent, having a combined capital and surplus of not less than
$50,000,000 and subject to supervision or examination by





                                      -79-
<PAGE>   94

Federal or State authority. If such Authenticating Agent publishes reports of
condition at least annually, pursuant to law or to the requirements of said
supervising or examining authority, then for the purposes of this Section, the
combined capital and surplus of such Authenticating Agent shall be deemed to be
its combined capital and surplus as set forth in its most recent report of
condition so published.  If at any time an Authenticating Agent shall cease to
be eligible in accordance with the provisions of this Section, such
Authenticating Agent shall resign immediately in the manner and with the effect
specified in this Section.

         Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency or
corporate trust business of an Authenticating Agent, shall continue to be an
Authenticating Agent, provided such corporation shall be otherwise eligible
under this Section, without the execution or filing of any paper or any further
act on the part of the Trustee or the Authenticating Agent.

         An Authenticating Agent may resign at any time by giving written
notice thereof to the Trustee and to the Company. The Trustee may at any time
terminate the agency of an Authenticating Agent by giving written notice
thereof to such Authenticating Agent and to the Company. Upon receiving such a
notice of resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall give notice of such
appointment in the manner provided in Section 106 to all Holders of Securities.
Any successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all the rights, powers and duties of its predecessor
hereunder, with like effect as if originally named as an Authenticating Agent.
No successor Authenticating Agent shall be appointed unless eligible under the
provisions of this Section.

         The Trustee agrees to pay to each Authenticating Agent from time to
time reasonable compensation for its services under this Section, and the
Trustee shall be entitled to be reimbursed for such payments, subject to the
provisions of Section 607.

         If an appointment is made pursuant to this Section, the Securities may
have endorsed thereon, in lieu of the





                                      -80-
<PAGE>   95

    such Holder.

         It shall not be necessary for any Act of Holders under this Section to
approve the particular form of any proposed supplemental indenture, but it
shall be sufficient if such Act shall approve the substance thereof.


SECTION 903.  Execution of Supplemental Indentures.

         In executing, or accepting the additional trusts created by, any

                                  ARTICLE TEN

                                   Covenants

SECTION 1001. Payment of Principal, Premium and 
              Interest.

         The Company will duly and punctually pay the principal of and premium,
if any, and interest on the Securities in accordance with the terms of the
Securities and this Indenture.


SECTION 1002. Maintenance of Office or Agency.

         The Company will maintain in the Borough of Manhattan, The City of New
York, New York, an office or agency where Securities may be presented or
surrendered for payment, where Securities may be surrendered for registration
of transfer or exchange and where notices and demands to or upon the Company in
respect of the Securities and this Indenture may be served.  The Company will
give prompt written notice to the Trustee of the location, and any change in
the location, of such office or agency.  If at any time the Company shall fail
to maintain any such required office or agency or shall fail to furnish the
Trustee with the address thereof, such presentations, surrenders, notices and
demands may be made or served at the Corporate Trust Office of the Trustee, and
the Company hereby appoints the Trustee as its agent to receive all such
presentations, surrenders, notices and demands.

         The Company may also from time to time designate one or more other
offices or agencies (in or outside the Borough of Manhattan, The City of New
York, New York) where the Securities may be presented or surrendered for any or
all such purposes and may from time to time rescind such designations;
provided, however, that no such designation or rescission shall in any manner
relieve the Company of its obligation to maintain an office or agency in the
Borough of Manhattan, The City of New York, New York for such purposes.  The
Company will give prompt written notice to the Trustee





                                      -89-
<PAGE>   104

of any such designation or rescission and of any change in the location of any
such other office or agency.


SECTION 1003. Money for Security
              Payments to be Held in Trust.

         If the Company shall at any time act as its own Paying Agent, it will,
on or before each due date of the principal of (and premium, if any) or
interest on any of the Securities, segregate and hold in trust for the benefit
of the Persons entitled thereto a sum sufficient to pay the principal (and
premium, if any) or interest so becoming due until such sums shall be paid to
such Persons or otherwise disposed of as herein provided and will promptly
notify the Trustee in writing of its action or failure so to act.  As provided
in Section 504, upon any bankruptcy or reorganization proceeding relative to
the Company, the Trustee shall serve as the Paying Agent for the Securities.

         Whenever the Company shall have one or more Paying Agents, it will,
prior to each due date of the principal of (and premium, if any) or interest on
any Securities, deposit with a Paying Agent a sum sufficient to pay the
principal (and premium, if any) or interest so becoming due, such sum to be
held in trust for the benefit of the Persons entitled to such principal,
premium or interest, and (unless such Paying Agent is the Trustee) the Company
will promptly notify the Trustee in writing of its action or failure so to act.
As provided in Section 504, upon any bankruptcy or reorganization proceeding
relative to the Company, the Trustee shall serve as the Paying Agent for the
Securities.

         The Company will cause each Paying Agent other than the Trustee to
execute and deliver to the Trustee an instrument in which such Paying Agent
shall agree with the Trustee, subject to the provisions of this Section, that
such Paying Agent will:

         (1)  hold all sums held by it for the payment of the principal of (and
    premium, if any) or interest on Securities in trust for the benefit of the
    Persons entitled thereto until such sums shall be paid to such Persons or
    otherwise disposed of as herein provided;

         (2)  give the Trustee notice of any default by the Company (or any
    other obligor upon the Securities) in the making of any payment of
    principal (and premium, if any) or interest;





                                      -90-
<PAGE>   105

         (3)  at any time during the continuance of any such default, upon the
    written request of the Trustee, forthwith pay to the Trustee all sums so
    held in trust by such Paying Agent; and

         (4)  acknowledge, accept and agree to comply in all respects with the
    provisions of this Indenture relating to the duties, rights and obligations
    of such Paying Agent.

         The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held
in trust by the Company or such Paying Agent, such sums to be held by the
Trustee upon the same trusts as those upon which such sums were held by the
Company or such Paying Agent; and, upon such payment by any Paying Agent to the
Trustee, such Paying Agent shall be released from all further liability with
respect to such money.

         Any money deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of the principal of (and premium, if
any) or interest on any Security and remaining unclaimed for two years after
such principal (and premium, if any) or interest has become due and payable
shall be paid to the Company on Company Request, or (if then held by the
Company) shall be discharged from such trust; and the Holder of such Security
shall thereafter, as an unsecured general creditor, look only to the Company
for payment thereof, and all liability of the Trustee or such Paying Agent with
respect to such trust money, and all liability of the Company as trustee
thereof, shall thereupon cease; provided, however, that the Trustee or such
Paying Agent, before being required to make any such repayment, may at the
expense of the Company cause to be published once, in a newspaper published in
the English language, customarily published on each Business Day and of general
circulation in the Borough of Manhattan, The City of New York, New York, notice
that such money remains unclaimed and that, after a date specified therein,
which shall not be less than 30 days from the date of such publication, any
unclaimed balance of such money then remaining will be repaid to the Company.


SECTION 1004. Existence.

         Subject to Article Eight, the Company will do or cause to be done all
things necessary to preserve and keep in full force and effect its existence,
rights (charter and





                                      -91-
<PAGE>   106

statutory) and franchises; provided, however, that the Company shall not be
required to preserve any such right or franchise if the Board of Directors
shall determine that the preservation thereof is no longer desirable in the
conduct of the business of the Company and that the loss thereof is not
disadvantageous in any material respect to the Holders.


SECTION 1005. Maintenance of Properties.

         The Company will cause all properties used or useful in the conduct of
its business or the business of any Subsidiary to be maintained and kept in
good condition, repair and working order and supplied with all necessary
equipment and will cause to be made all necessary repairs, renewals,
replacements, betterments and improvements thereof, all as in the judgment of
the Company may be necessary so that the business carried on in connection
therewith may be properly and advantageously conducted at all times; provided,
however, that nothing in this Section shall prevent the Company from
discontinuing the operation or maintenance of any of such properties if such
discontinuance is, as determined in the good faith judgment of the Board of
Directors evidenced by a Board Resolution, desirable in the conduct of its
business or the business of any Subsidiary and not disadvantageous in any
material respect to the Holders.


SECTION 1006. Payment of Taxes and Other Claims.

such Subsidiary.  For any transaction that involves in excess of $1.0 million
but less than or equal to $5.0 million, the Chief Executive Officer of the

Company to, enter into any Sale and Leaseback Transaction unless (i) the
Company or such Subsidiary would be entitled to Incur a Lien to secure Debt by
reason of the provisions of Section 1015 of this Indenture, equal in amount to
the Attributable Value of the Sale and Leaseback Transaction without equally
and ratably securing the Securities or (ii) the Sale and Leaseback Transaction
is treated as an Asset Disposition and all of the conditions of Section 1013 of
this Indenture (including the provisions concerning the application of Net
Available Proceeds) are satisfied with respect to such Sale and Leaseback
Transaction, treating all of the consideration received in such Sale and
Leaseback Transaction as Net Available Proceeds for purposes of such covenant.


SECTION 1017. Change of Control.

         (a)  Upon the occurrence of a Change of Control (as defined below),
each Holder of a Security shall have the right to have such Security
repurchased by the Company on the terms and conditions precedent set forth in
this Section 1017 and this Indenture.  The Company shall, within 30 days
following the date of the consummation of a transaction resulting in a Change
of Control, mail an Offer with respect to an Offer to Purchase all Outstanding
Securities at a





                                     -104-
<PAGE>   119

purchase price equal to 101% of their Accreted Value (if such Offer to Purchase
is made on or prior to November 1, 2001) or 101% of their principal amount plus
accrued interest to the date of purchase (if such Offer to Purchase is
consummated thereafter).  Installments of interest (including Special Interest)
whose Stated Maturity is on or prior to the Purchase Date shall be payable to
the Holders of such Securities, or one or more Predecessor Securities,
registered as such at the close of business on the relevant Record Dates
according to their terms and the provisions of Section 307.  Each Holder shall
be entitled to tender all or any portion of the Securities owned by such Holder
pursuant to the Offer to Purchase, subject to the requirement that any portion
of a Security tendered must be tendered in an integral multiple of $1,000
principal amount.

         (b)  The Company and Trustee shall perform their respective
obligations specified in the Offer for the Offer to Purchase.  Prior to the
Purchase Date, the Company shall (i) accept for payment Securities or portions
thereof tendered pursuant to the Offer, (ii) deposit with the Paying Agent (or,
if the Company is acting as its own Paying Agent, segregate and hold in trust
as provided in Section 1003) money sufficient to pay the purchase price of all
Securities or portions thereof so accepted and (iii) deliver or cause to be
delivered to the Trustee all Securities so accepted together with an Officers'
Certificate stating the Securities or portions thereof accepted for payment by
the Company.  The Paying Agent shall promptly mail or deliver to Holders of
Securities so accepted payment in an amount equal to the purchase price, and
the Trustee shall promptly authenticate and mail or deliver to such Holders a
new Security or Securities equal in principal amount to any unpurchased portion
of the Security surrendered as requested by the Holder.  Any Security not
accepted for payment shall be promptly mailed or delivered by the Company to
the Holder thereof.

         (c)  A "Change of Control" shall be deemed to have occurred in the
event that, after the date of this Indenture, either (A) any Person or any
Persons acting together that would constitute a "group" (a "Group") for
purposes of Section 13(d) of the Exchange Act, or any successor provision
thereto, together with any Affiliates or Related Persons thereof, shall
beneficially own (as defined in Rule 13d-3 of the Exchange Act or any successor
provision thereto) at least 50% of the aggregate voting power of all classes of
Voting Stock of the Company; or (B) any Person or Group, together with any
Affiliates or Related Persons thereof, shall succeed in having a sufficient
number of its or their nominees elected to the Board of Directors of the





                                     -105-
<PAGE>   120

Company such that such nominees, when added to any existing director or
directors remaining on the Board of Directors of the Company after such
election who was a nominee of or is an Affiliate or Related Person of such
Person or Group (excluding in each case any nominee that is a Continuing
Director), shall constitute a majority of the Board of Directors of the
Company.

         (d)  In the event that the Company makes an Offer to Purchase the
Securities, the Company shall comply with any applicable securities laws and
regulations, including any applicable requirements of Section 14(e) of, and
Rule 14e-1 under, the Securities Exchange Act of 1934.


SECTION 1018.  Provision of Financial Information.

         The Company shall file with the Trustee within 15 days after it files
them with the Commission copies of the annual and quarterly reports and the
information, documents, and other reports that the Company is required to file
with the Commission pursuant to Section 13(a) or 15(d) of the Exchange Act
("SEC Reports").  In the event the Company shall cease to be required to file
SEC Reports pursuant to the Exchange Act, the Company shall nevertheless
continue to file such reports with the Commission (unless the Commission will
not accept such a filing) and the Trustee.  The Company shall furnish copies of
the SEC Reports to the holders of Securities at the time the Company is
required to file the same with the Trustee and will make such information
available to investors who request it in writing.


SECTION 1019.  Statement by Officers as to Default.

         (a)  The Company will deliver to the Trustee, within 120 days after
the end of each fiscal year of the Company ending after the date hereof, an
Officers' Certificate, stating whether or not to the best knowledge of the
signers thereof the Company is in default in the performance and observance of
any of the terms, provisions and conditions of Sections 1004 to 1018,
inclusive, and if the Company shall be in default, specifying all such defaults
and the nature and status thereof of which they may have knowledge.

         (b)  The Company shall deliver to the Trustee, as soon as possible and
in any event within 10 days after the Company becomes aware of the occurrence
of an Event of Default or an event which, with notice or the lapse of time or
both, would constitute an Event of Default, an Officers' Certificate setting
forth the details of such Event of





                                     -106-
<PAGE>   121

Default or default and the action which the Company proposes to take with
respect thereto.


SECTION 1020.  Waiver of Certain Covenants.

         The Company may omit in any particular instance to comply with any
covenant or condition set forth in Sections 1004 to 1017, inclusive, if before
or after the time for such compliance the Holders of at least a majority in
aggregate principal amount of the Outstanding Securities shall, by Act of such
Holders, either waive such compliance in such instance or generally waive
compliance with such covenant or condition, but no such waiver shall extend to
or affect such covenant or condition except to the extent so expressly waived,
and, until such waiver shall become effective, the obligations of the Company
and the duties of the Trustee in respect of any such covenant or condition
shall remain in full force and effect.



                                 ARTICLE ELEVEN

                            Redemption of Securities

SECTION 1101.  Right of Redemption.

         (a)  The Securities may be redeemed prior to November 1, 2001 only in
the event that the Company receives net proceeds from any sale of its Common
Stock (other than Disqualified 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 Securities in a principal
amount of up to an aggregate amount equal to 33 1/3% of the original principal
amount of the Securities provided, however, that Securities in an amount equal
to at least 66 2/3% of the original principal amount of the Securities remain
outstanding after such redemption.  Such redemption must occur on a Redemption
Date within 75 days of any such sale and upon not less than 30 nor more than 60
days' notice by mail to each Holder of Securities to be redeemed at such
Holder's address appearing in the Security 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 Securities to but excluding the Redemption Date (subject to the
right of Holders of record on the relevant Regular Record Date to receive
Special Interest due on an Interest Payment Date that is on or prior to the
Redemption Date).





                                     -107-
<PAGE>   122

         (b)  The Securities further may be redeemed, as a whole or in part, at
the election of the Company, at any time on or after November 1, 2001 and prior
to maturity, upon not less than 30 nor more than 60 days' notice by mail to
each Holder of Securities to be redeemed at such Holder's address appearing in
the Security Register, in amounts of $1,000 or an integral multiple of $1,000,
at the Redemption Prices specified in the form of Security hereinbefore set
forth, together with accrued interest to, but excluding, the Redemption Date.


SECTION 1102.  Applicability of Article.

         Redemption of Securities at the election of the Company, as permitted
or required by any provision of this Indenture, shall be made in accordance
with such provision and this Article.


SECTION 1103.  Election to Redeem; Notice to Trustee.

         The election of the Company to redeem any Securities pursuant to
Section 1101 shall be evidenced by a Board Resolution.  In case of any
redemption at the election of the Company of less than all the Securities, the
Company shall, at least 60 days prior to the Redemption Date fixed by the
Company (unless a shorter notice shall be satisfactory to the Trustee), notify
the Trustee in writing of such Redemption Date and of the principal amount of
Securities to be redeemed. In the case of any redemption of Securities prior to
the expiration of any restriction on such redemption provided in the terms of
such Securities or elsewhere in this Indenture, the Company shall furnish the
Trustee with an Officers' Certificate evidencing compliance with such
restriction.


SECTION 1104.  Securities to Be Redeemed Pro Rata.

         If less than all the Securities are to be redeemed in any redemption,
the Securities to be redeemed shall be selected by the Trustee by prorating, as
nearly as may be practicable, the principal amount of Securities to be
redeemed.  In any proration pursuant to this Section, the Trustee shall make
such adjustments, reallocations and eliminations as it shall deem proper to the
end that the principal amount of Securities so prorated shall be $1,000 or a
multiple thereof, by increasing or decreasing or eliminating the amount which
would be allocable to any Holder on the basis of exact proportion by an amount
not





                                     -108-
<PAGE>   123

exceeding $1,000.  The Trustee in its discretion may determine the particular
Securities (if there are more than one) registered in the name of any Holder
which are to be redeemed, in whole or in part.

         The Trustee shall promptly notify the Company and each Security
Registrar in writing of the Securities selected for redemption and, in the case
of any Securities selected for partial redemption, the principal amount thereof
to be redeemed.

         For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Securities shall relate,
in the case of any Securities redeemed or to be redeemed only in part, to the
portion of the principal amount of such Securities which has been or is to be
redeemed.


SECTION 1105.  Notice of Redemption.

         Notice of redemption shall be given by first-class mail, postage
prepaid, mailed not less than 30 nor more than 60 days prior to the Redemption
Date, to each Holder of Securities to be redeemed, at such Holder's address
appearing in the Security Register.

         All notices of redemption shall state:

         (1)  the Redemption Date,

         (2)  the Redemption Price,

         (3)  whether the redemption is being made pursuant to Section 1101(a)
    or (b) and, if being made pursuant to Section 1101(a), a brief statement
    setting forth the Company's right to effect such redemption and the
    Company's basis therefor,

         (4)  if less than all the Outstanding Securities are to be redeemed,
    the identification (and, in the case of partial redemption of any
    Securities, the principal amounts) of the particular Securities to be
    redeemed,

         (5)  that on the Redemption Date the Redemption Price will become due
    and payable upon each such Security to be redeemed and that interest
    thereon will cease to accrue on and after said date,

         (6)  the place or places where such Securities are to be surrendered
    for payment of the Redemption Price, and





                                     -109-
<PAGE>   124


         (7)  that in the case that a Security is only redeemed in part, the
    Company shall execute and the Trustee shall authenticate and deliver to the
    Holder of such Security without service charge, a new Security or
    Securities in an aggregate amount equal to the unredeemed portion of the
    Security.

         Notice of redemption of Securities to be redeemed at the election of
the Company shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company.


SECTION 1106.  Deposit of Redemption Price.

         Prior to any Redemption Date, the Company shall deposit with the
Trustee or with a Paying Agent (or, if the Company is acting as its own Paying
Agent, segregate and hold in trust as provided in Section 1003) an amount of
money sufficient to pay the Redemption Price of, and (except if the Redemption
Date shall be an Interest Payment Date) accrued interest on, all the Securities
which are to be redeemed on that date.


SECTION 1107.  Securities Payable on Redemption Date.

         Notice of redemption having been given as aforesaid, the Securities so
to be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to bear interest.  Upon surrender of any
such Security for redemption in accordance with said notice, such Security
shall be paid by the Company at the Redemption Price, together with accrued
interest to the Redemption Date; provided, however, that installments of
interest whose Stated Maturity is on or prior to the Redemption Date shall be
payable to the Holders of such Securities, or one or more Predecessor
Securities, registered as such at the close of business on the relevant Record
Dates according to their terms and the provisions of Section 307.

         If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal (and premium, if any) shall,
until paid, bear interest from the Redemption Date at the rate provided by the
Security.





                                     -110-
<PAGE>   125

SECTION 1108.  Securities Redeemed in Part.

         Any Security which is to be redeemed only in part shall be surrendered
at an office or agency of the Company designated for that purpose pursuant to
Section 1002 (with, if the Company or the Trustee so requires, due endorsement
by, or a written instrument of transfer in form satisfactory to the Company and
the Trustee duly executed by, the Holder thereof or his attorney duly
authorized in writing), and the Company shall execute, and the Trustee shall
authenticate and deliver to the Holder of such Security without service charge,
a new Security or Securities of like tenor, of any authorized denomination as
requested by such Holder, in aggregate principal amount equal to and in
exchange for the unredeemed portion of the principal of the Security so
surrendered.



                                 ARTICLE TWELVE

                       Defeasance and Covenant Defeasance

SECTION 1201.  Company's Option to Effect Defeasance or
               Covenant Defeasance.

         The Company may at its option by Board Resolution, at any time
(subject to 10-day prior written notification to the Trustee), elect to have
either Section 1202 or Section 1203 applied to the Outstanding Securities upon
compliance with the conditions set forth below in this Article Twelve.


SECTION 1202.  Defeasance and Discharge.

         Upon the Company's exercise of the option provided in Section 1201
applicable to this Section, the Company  shall be deemed to have been
discharged from its obligations with respect to the Outstanding Securities on
the date the conditions set forth below are satisfied (hereinafter,
"defeasance").  For this purpose, such defeasance means that the Company shall
be deemed to have paid and discharged the entire indebtedness represented by
the Outstanding Securities and to have satisfied all its other obligations
under such Securities and this Indenture insofar as such Securities are
concerned (and the Trustee, at the expense of the Company, shall execute proper
instruments acknowledging the same), except for the following which shall
survive until otherwise terminated or discharged hereunder:  (A) the rights of
Holders of Outstanding Securities to receive,





                                     -111-
<PAGE>   126

solely from the trust fund described in Section 1204 and as more fully set
forth in such Section, payments in respect of the principal of (and premium, if
any) and interest on such Securities when such payments are due, (B) the
Company's obligations with respect to such Securities under Sections 304, 305,
306, 1002 and 1003, (C) the rights, powers, trusts, duties and immunities of
the Trustee hereunder and (D) this Article Twelve.  Subject to compliance with
this Article Twelve, the Company may exercise its option under this Section
1202 notwithstanding the prior exercise of its option under Section 1203.


SECTION 1203.  Covenant Defeasance.

         Upon the Company's exercise of the option provided in Section 1201
applicable to this Section (i) the Company shall be released from its
obligations under Sections 1005 through 1018, inclusive, and Clauses (3) and
(4) of Section 801, (ii) the occurrence of an event specified in Sections
501(3), 501(4) (with respect to Clauses (3) and (4)  of Section 801), and 501
(5) (with respect to Sections 1005 through 1018, inclusive) shall not be deemed
to be an Event of Default, on and after the date the conditions set forth below
are satisfied (hereinafter, "covenant defeasance").  For this purpose, such
covenant defeasance means that the Company may omit to comply with and shall
have no liability in respect of any term, condition or limitation set forth in
any such Section or Article, whether directly or indirectly by reason of any
reference elsewhere herein to any such Section or Article or by reason of any
reference in any such Section or Article to any other provision herein or in
any other document, but the remainder of this Indenture and such Securities
shall be unaffected thereby.


SECTION 1204.  Conditions to Defeasance or
               Covenant Defeasance.

         The following shall be the conditions to application of either Section
1202 or Section 1203 to the Outstanding Securities:

         (1)  The Company shall irrevocably have deposited or caused to be
    deposited with the Trustee (or another trustee satisfying the requirements
    of Section 609 who shall agree to comply with the provisions of this
    Article Twelve applicable to it) as trust funds in trust for the purpose of
    making the following payments, specifically pledged as security for, and
    dedicated solely to, the benefit of the Holders of such Securities, (A)
    money in





                                     -112-
<PAGE>   127

    an amount, or (B) U.S. Government Obligations which through the scheduled
    payment of principal and interest in respect thereof in accordance with
    their terms will provide, not later than one day before the due date of any
    payment, money in an amount, or (C) a combination thereof, sufficient, in
    the opinion of a nationally recognized accounting firm expressed in a
    written certification thereof delivered  to the Trustee, to pay and
    discharge, and which shall be applied by the Trustee (or other qualifying
    trustee) to pay and discharge, the principal of, premium, if any, and each
    installment of interest on the Securities on the Stated Maturity of such
    principal or installment of interest on the day on which such payments are
    due and payable in accordance with the terms of this Indenture and of such
    Securities.  For this purpose, "U.S. Government Obligations" means
    securities that are (x) direct obligations of the United States of America
    for the payment of which its full faith and credit is pledged or (y)
    obligations of a Person controlled or supervised by and acting as an agency
    or instrumentality of the United States of America the payment of which is
    unconditionally guaranteed as a full faith and credit obligation by the
    United States of America, which, in either case, are not callable or
    redeemable at the option of the issuer thereof, and shall also include a
    depository receipt issued by a bank (as defined in Section 3(a)(2) of the
    Securities Act) as custodian with respect to any such U.S.  Government
    Obligation or a specific payment of principal of or interest on any such
    U.S. Government Obligation held by such custodian for the account of the
    holder of such depository receipt, provided that (except as required by
    law) such custodian is not authorized to make any deduction from the amount
    payable to the holder of such depository receipt from any amount received
    by the custodian in respect of the U.S. Government Obligation or the
    specific payment of principal of or interest on the U.S. Government
    Obligation evidenced by such depository receipt.

         (2)  No Event of Default or event which with notice or lapse of time
    or both would become an Event of Default shall have occurred and be
    continuing on the date of such deposit or, insofar as subsections 501(8)
    and (9) are concerned, at any time during the period ending on the 91st day
    after the date of such deposit (it being understood that this condition
    shall not be deemed satisfied until the expiration of such period).

         (3)  Such defeasance or covenant defeasance shall not cause the
    Trustee to have a conflicting interest as





                                     -113-
<PAGE>   128

    defined in Section 608 and for purposes of the Trust Indenture Act with
    respect to any securities of the Company.

         (4)  Such defeasance or covenant defeasance shall not result in a
    breach or violation of, or constitute a default under, this Indenture or
    any other agreement or instrument to which the Company is a party or by
    which it is bound.

         (5)  The Company shall have delivered to the Trustee an Officers'
    Certificate and an Opinion of Counsel, each stating that all conditions
    precedent provided for relating to either the defeasance under Section 1202
    or the covenant defeasance under Section 1203 (as the case may be) have
    been complied with.

         (6)  In the case of an election under Section 1202, the Company shall
    have delivered to the Trustee an Opinion of Counsel stating that (x) the
    Company has received from, or there has been published by, the Internal
    Revenue Service a ruling, or (y) since the date of this Indenture there has
    been a change in the applicable Federal income tax law, in either case to
    the effect that, and based thereon such opinion shall confirm that, the
    Holders of the Outstanding Securities will not recognize income, 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.

         (7)  In the case of an election under Section 1203, the Company shall
    have delivered to the Trustee an Opinion of Counsel to the effect that the
    Holders of the Outstanding Securities will not recognize income, gain or
    loss for Federal income tax purposes as a result of such deposit and
    covenant 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 covenant defeasance had not occurred.

         (8)  The Company shall have delivered to the Trustee an Opinion of
    Counsel to the effect that such deposit and defeasance or covenant
    defeasance shall not result in the trust arising from such deposit
    constituting an investment company as defined in the Investment Company Act
    of 1940, as amended, or such trust shall be qualified under such act or
    exempt from regulation thereunder.

SECTION 1205.  Deposited Money and U.S. Government Obligations to Be 
               Held in Trust; Other Miscellaneous Provisions.

         Subject to the provisions of the last paragraph of Section 1003, all
money and U.S. Government Obligations  (including the proceeds thereof)
deposited with the Trustee (or other qualifying trustee--collectively, for
purposes of this Section 1205, the "Trustee") pursuant to Section 1204 in
respect of the Securities shall be held in trust and applied by the Trustee, in
accordance with the provisions of such Securities and this Indenture, to the
payment, either directly or through any Paying Agent (including the Company
acting as its own Paying Agent) as the Trustee may determine, to the Holders of
such Securities, of all sums due and to become due thereon in respect of
principal (and premium, if any) and interest, but such money need not be
segregated from other funds except to the extent required by law.

         The Company shall pay and indemnify the Trustee against any tax, fee
or other charge imposed on or assessed against the U.S. Government Obligations
deposited pursuant to Section 1204 or the principal and interest received in
respect thereof other than any such tax, fee or other charge which by law is
for the account of the Holders of the Outstanding Securities.

         Anything in this Article Twelve to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon Company
Request any money or U.S. Government Obligations held by it as provided in
Section 1204 which, in the opinion of a nationally recognized accounting firm
expressed in a written certification thereof delivered to the Trustee, are in
excess of the amount thereof which would then be required to be deposited to
effect an equivalent defeasance or covenant defeasance.

                         ____________________________
         This instrument may be executed in any number of counterparts, each of
which so executed shall be deemed to be an original, but all such counterparts
shall together constitute but one and the same instrument.

         2. Registration Under the Securities Act.

         (a)  Except as set forth in Section 2(b) below, the Company agrees to
use its best efforts to file under the Securities Act no later than 60 days
after the Closing Date, a registration statement relating to an offer to
exchange (the "Exchange Offer") for a like aggregate principal amount of debt
securities of the Company which are substantially identical to the Securities
(and which are entitled to the benefits of a trust indenture which is
substantially identical to the Indenture or is the Indenture and which has been
qualified under the Trust Indenture Act) except that they have been registered
pursuant to an effective registration statement under the Securities Act (such
new debt securities hereinafter called "Exchange Securities") for any or all of
the Registrable Securities. The Company agrees to use its reasonable best
efforts to cause such registration statement to become effective under the
Securities Act no later than 90 days after the Closing Date.  The Exchange
Offer will be registered under the Act on the appropriate form and will comply
with all applicable tender offer rules and regulations under the Exchange Act.
The Company further agrees to commence and complete the Exchange Offer promptly
after such registration statement has become effective, hold the Exchange Offer
open for at least 30 days and exchange Exchange Securities for all Registrable
Securities that have been tendered and not withdrawn on or prior to the
expiration of the Exchange Offer. The Exchange Offer will be deemed to have
been completed only if the Exchange Securities received by holders other than
Restricted Holders in the Exchange Offer for Registrable Securities are, upon
receipt, transferable by each such holder without restriction under the
Securities Act and the Exchange Act and without material restrictions under the
blue sky or securities laws of a substantial majority of the States of the
United States of America. The Exchange Offer shall be deemed to have been
completed upon the earlier to occur of (i) the Company having exchanged the
Exchange Securities for all outstanding Registrable Securities pursuant to the
Exchange Offer and (ii) the Company having exchanged, pursuant to the Exchange
Offer, Exchange Securities for all Registrable Securities that have been
tendered and not withdrawn before the expiration of the Exchange Offer, which
shall be on a date that is at least 30 days following the commencement of the
Exchange Offer. The Company agrees (i) to include in the registration statement
a prospectus for use in connection with any resales by any holder of Exchange
Securities that is a broker-dealer and (ii) to keep such registration statement
effective for a period ending on the earlier of the 90th day after the Exchange
Offer has been completed or such time as such broker-dealers no longer own any
Registrable Securities. With respect to such registration statement the Company
and any such holder shall have the benefit of, and shall each provide to the
other, the rights of indemnification and contribution set forth in Section 6
hereof.

         (b)  If prior to the consummation of the Exchange Offer existing
Commission interpretations are changed such that the Exchange Securities
received by holders other than Restricted Holders in the Exchange Offer for
Registrable Securities are not or would not be, upon receipt, transferable by
each such holder without restriction under the Securities Act, in lieu of
conducting the Exchange Offer contemplated by Section 2(a) the Company shall
file under the Securities Act a "shelf" registration statement providing for
the registration of, and the sale on a continuous or delayed basis by the
holders of, all of the Registrable Securities, pursuant to Rule 415 under the
Securities Act and/or any similar rule that may be adopted by the Commission
(the "Shelf Registration"). The Company agrees to use its reasonable best
efforts to cause the Shelf Registration to become or be declared effective no
later than 90 days after the Closing Date and to keep such Shelf Registration
continuously effective for a period ending on the earlier of the





                                      -3-
<PAGE>   4

third anniversary of the Closing Date or such time as there are no longer any
Registrable Securities outstanding.  The Company further agrees to supplement
or make amendments to the Shelf Registration, as and when required by the
rules, regulations or instructions applicable to the registration form used by
the Company for such Shelf Registration or by the Securities Act or rules and
regulations thereunder for shelf registration, and the Company agrees to
furnish to the holders of the Registrable Securities copies of any such
supplement or amendment prior to its being used and/or filed with the
Commission.

         (c)  In the event that (i) the Company has not filed the registration
statement relating to the Exchange Offer (or, if applicable, the Shelf
Registration) on or before the 60th day after the Closing Date, or (ii) such
registration statement or, in lieu thereof, the Shelf Registration, has not
become effective or been declared effective by the Commission on or before the
90th day after the Closing Date, or (iii) the Exchange Offer has not been
completed within 45 days after the initial effective date of the registration
statement (if the Exchange Offer is then required to be made) or (iv) any
registration statement required by Section 2(a) or 2(b) is filed and declared
effective but shall thereafter cease to be effective (except as specifically
permitted herein) without being succeeded promptly by an additional
registration statement filed and declared effective (each such event referred
to in clauses (i) through (iv), a "Registration Default"), then interest will
accrue (in addition to the original issue discount and any stated interest on
the Securities) at the rate of 0.5% per annum on the Accreted Value (as defined
in the Indenture) of the Securities (or after November 1, 2001, on the
principal amount of the Securities), determined daily (calculated on the same
basis as Accreted Value of or interest on the Securities, as the case may be,
shall be calculated) for the period from the occurrence of the Registration
Default until such time as no Registration Default is in effect (after which
time no such special interest will accrue). Such special interest (the "Special
Interest") will be payable in cash semi-annually in arrears on each May 1 and
November 1 in accordance with the Indenture. In addition, in the event that the
Exchange Offer has not been completed or, if applicable, the Shelf Registration
has not become effective or been declared effective by the Commission on or
before the 135th day after the Closing Date, then the per annum rate of Special
Interest shall increase by an additional 0.5%, and Special Interest will be
paid at such increased rate until such time as the Company completes the
Exchange Offer or, if applicable, the Shelf Registration has become or been
declared effective.

         (d)  In the event that either of the Purchasers shall not have sold
all of the Securities initially purchased by it pursuant to the Purchase
Agreement within 60 days after the Closing Date and such Purchaser requests on
the business day following the expiration of such 60- day period that the
Company register a resale of such unsold Securities, the Company shall file
under the Securities Act as soon as practicable after receipt of such request a
registration statement on the appropriate form covering a resale of such unsold
Securities (the "Resale Registration") and will use its reasonable best efforts
to cause such registration statement to become effective under the Securities
Act as promptly as practicable and to keep such registration statement
continuously effective pursuant to Rule 415 under the Securities Act and/or any
similar rule that may be adopted by the Commission for a period of up to 30
days.

Shelf Registration or any Resale Registration, if applicable, the Company shall

         Act), if any, thereof, (C) the sales or placement agent, if any,
         therefor, and (D) one counsel for such underwriters or agents, if any,

         registration statement, and throughout the period specified in Section
         2(b) or Section 2(d), as applicable, make available at reasonable
         times at the Company's principal place of business or such other

         3(c)(iv) who shall certify to the Company that they have a current
         intention to sell the Registrable Securities pursuant to the Shelf
         Registration or Resale Registration such financial and other
         information and books and records of the Company, and cause the

         of this Agreement), or (B) such person shall be required so to
         disclose such information pursuant to the subpoena or order of any
         court or other governmental agency or body having jurisdiction over

         (C) such information is required to be set forth in such registration
         statement or the prospectus included therein or in an amendment to
         such registration statement or an amendment or supplement to such
         prospectus in order that such registration statement, prospectus,
         amendment or supplement, as the case may be, does not contain an
         untrue statement of a material fact or omit to state therein a

         at any time when a prospectus is required to be delivered under the
         Securities Act, that such registration statement, prospectus,

         document incorporated by reference in any of the foregoing, contains
         an untrue statement of a material fact or omits to state any material
         fact required to be stated therein or necessary to make the statements

                  (vii) use its reasonable best efforts to obtain the

         Section 2(d) above, as applicable, and for so long as may be necessary
         to enable any such

         Securities; provided, however, that the Company shall not be required
         for any such purpose to (1) qualify as a foreign corporation in any

         the disposition of, their Registrable Securities;

                 (xii) cooperate with the holders of the Registrable Securities
         and the managing underwriters, if any, to facilitate the timely
         preparation and delivery of certificates representing Registrable
         Securities to be sold, which certificates shall be printed,
         lithographed or engraved, or produced by any combination of such

         least 25% in aggregate principal amount of the Registrable Securities
         included in such Shelf Registration or Resale Registration shall
         request in order to expedite or facilitate the disposition of such
         Registrable Securities; provided, that the Company shall not be
         required to enter into any such agreement more than once with respect
         to all of the Registrable Securities and may delay entering into such
         agreement until the consummation of any underwritten public offering
         which the Company shall have then undertaken;

                  (xv) whether or not an agreement of the type referred to in
         Section (3)(c)(xiv) hereof is entered into and whether or not any
         portion of the offering contemplated by such registration statement is
         an underwritten offering or is made through a placement or sales agent
         or any other entity, (A) make such representations and warranties to
         the holders of such Registrable Securities and the placement or sales
         agent, if any, therefor and the underwriters, if any, thereof
         substantially the same as those set forth in Section 1 of the Purchase
         Agreement and such other representations and warranties as are
         customarily made with respect to the offering

         of debt securities pursuant to a shelf registration statement on the
         applicable form under the Act; (B) obtain an opinion or opinions of
         counsel to the Company substantially the same as the opinions provided

         underwriters, if any, thereof and dated the effective date of such
         registration statement (and if such registration statement
         contemplates an underwritten offering of a part or all of the
         Registrable Securities, dated the date of the closing under the
         underwriting agreement relating thereto) (it being agreed that the
         matters to be covered by such opinion shall also include, without
         limitation, the absence of governmental approvals required to be
         obtained in connection with the Shelf Registration or Resale
         Registration, the offering and sale of the Registrable Securities,
         this Exchange and Registration Rights Agreement or any agreement of
         the type referred to in Section (3)(c)(xiv) hereof, except such
         approvals as may be required under state securities or blue sky laws;
         and the compliance as to form of such registration statement and any
         documents incorporated by reference therein and of the Indenture with
         the requirements of the Securities Act and the Trust Indenture Act,
         respectively; and, such opinion shall also state that such counsel has
         no reason to believe that, as of the date of the opinion and of the
         registration statement or most recent post-effective amendment
         thereto, as the case may be, such registration statement and the
         prospectus included therein, as then amended or supplemented, and the
         documents incorporated by reference therein (in each case other than
         the financial statements and other financial information contained
         therein) contains or contained an untrue statement of a material fact
         or omits or omitted to state therein a material fact necessary to make

         in the light of the circumstances existing at the time that such
         documents were filed with the Commission under the Exchange Act)); (C)
         obtain a "cold comfort" letter or letters from the independent
         certified public accountants of the Company addressed to the selling

         any, therefor and the underwriters, if any, thereof, dated (i) the
         effective date of such registration statement and (ii) the effective
         date of any prospectus supplement to the prospectus included in such
         registration statement or post-effective amendment to such
         registration statement which includes unaudited or audited financial
         statements as of a date or for a period subsequent to that of the
         latest such statements included in such prospectus (and, if such
         registration statement contemplates an underwritten offering pursuant
         to any prospectus supplement to the prospectus included in such
         registration statement or post-effective amendment to such
         registration statement which includes unaudited or audited financial
         statements as of a date or for a period subsequent to that of the
         latest such statements included in such prospectus, dated the date of
         the closing under the underwriting agreement relating thereto), such
         letter or letters to be in customary form and covering such matters of
         the type customarily covered by letters of such type; (D) deliver such
         other documents and certificates, including officers' certificates, as
         may be reasonably requested by any holders of at least 25% in
         aggregate principal amount of the Registrable Securities included in
         such Shelf Registration or Resale Registration or the placement or
         sales agent, if any, therefor and the managing underwriters, if any,

         made pursuant to clause (A) above or those contained in Section 5(a)
         hereof and the compliance with or satisfaction of any agreements or
         conditions contained in the underwriting agreement or other agreement
         entered into by the Company; and (E) undertake such obligations
         relating to expense reimbursement, indemnification and contribution as
         are provided in Section 6 hereof;

<PAGE>   10

                 (xvi) notify in writing each holder of Registrable Securities
         of any proposal by the Company to amend or waive any provision of this
         Exchange and Registration Rights Agreement pursuant to Section 9(h)
         hereof and of any amendment or waiver effected pursuant thereto, each
         of which notices shall contain the text of the amendment or waiver
         proposed or effected, as the case may be; and

                 (xvii) in the event that any broker-dealer registered under
         the Exchange Act shall underwrite any Registrable Securities or
         participate as a member of an underwriting syndicate or selling group
         or "participate in the distribution" (within the meaning of the
         Conduct Rules and the By-Laws of the National Association of
         Securities Dealers, Inc. ("NASD") or any successor thereto, as amended
         from time to time) thereof, whether as a holder of such Registrable
         Securities or as an underwriter, a placement or sales agent or a
         broker or dealer in respect thereof, or otherwise, assist such
         broker-dealer in complying with the requirements of such Rules and
         By-Laws, including, without limitation, by (A) if such Rules or
         By-Laws, including Rule 2720 (or any successor thereto), shall so
         require, engaging a "qualified independent underwriter" (as defined in
         Rule 2720 (or any successor thereto)) to participate in the
         preparation of the registration statement relating to such Registrable
         Securities, to exercise usual standards of due diligence in respect
         thereto and, if any portion of the offering contemplated by such
         registration statement is an underwritten offering or is made through
         a placement or sales agent, to recommend the yield of such Registrable
         Securities, (B) indemnifying any such qualified independent
         underwriter to the extent of the indemnification of underwriters
         provided in Section 6 hereof, and (C) providing such information to
         such broker-dealer as may be required in order for such broker-dealer
         to comply with the requirements of the Conduct Rules of the NASD.

         (d) In the event that the Company would be required, pursuant to
Section 3(c)(vi)(F) above, to notify the selling holders of Registrable
Securities, the placement or sales agent, if any, therefor and the managing
underwriters, if any, thereof, the Company shall without delay prepare and
furnish to each such holder, to each placement or sales agent, if any, and to
each underwriter, if any, a reasonable number of copies of a prospectus
supplemented or amended so that, as thereafter delivered to purchasers of
Registrable Securities, such prospectus shall not contain an untrue statement
of a material fact or omit to state a material fact required to be stated
therein or necessary to make the statements therein not misleading in light of
the circumstances then existing. Each holder of Registrable Securities agrees
that upon receipt of any notice from the Company pursuant to Section
3(c)(vi)(F) hereof, such holder shall forthwith discontinue the disposition of
Registrable Securities, pursuant to the registration statement applicable to
such Registrable Securities until such holder shall have received copies of
such amended or supplemented prospectus, and if so directed by the Company,
such holder shall deliver to the Company (at the Company's expense) all copies,
other than permanent file copies, then in such holder's possession of the
prospectus covering such Registrable Securities at the time of receipt of such
notice.

         (e) The Company may require each holder of Registrable Securities as
to which any registration is being effected to furnish in writing to the
Company such information regarding such holder and such holder's intended
method of distribution of such Registrable Securities as the Company may from
time to time reasonably request in writing, but only to the extent that such
information is required in order to comply with the Securities Act, and may
exclude from





                                      -10-
<PAGE>   11

any such registration the Registrable Securities of any such holder who fails
to furnish such reasonably requested information within 30 days after such
request. Each such holder agrees to notify the Company as promptly as
practicable of any inaccuracy or change in information previously furnished by
such holder to the Company or of the occurrence of any event in either case as
a result of which any prospectus relating to such registration contains or
would contain an untrue statement of a material fact regarding such holder or
such holder's intended method of distribution of such Registrable Securities or
omits to state any material fact regarding such holder or such holder's
intended method of distribution of such Registrable Securities required to be
stated therein or necessary to make the statements therein not misleading in
light of the circumstances then existing, and promptly to furnish to the
Company any additional information required to correct and update any
previously furnished information or required so that such prospectus shall not
contain, with respect to such holder or the distribution of such Registrable
Securities, an untrue statement of a material fact or omit to state a material
fact required to be stated therein or necessary to make the statements therein
not misleading in light of the circumstances then existing. Each such holder
shall comply with the provisions of the Securities Act applicable to such
holder with respect to the disposition by such holder of Registrable Securities
covered by such registration statement in accordance with the intended methods
of disposition by such holder set forth in such registration statement.

         (f)  Until three years after the Closing Date, the Company will not,
and will not permit any of its "affiliates" (as defined in Rule 144 under the
Act) to, resell any of the Securities which constitute "restricted securities"
under Rule 144 that have been reacquired by any of them except pursuant to an
effective registration statement under the Act or any exemption therefrom.

         4. Registration Expenses.

         If the Company files a registration statement pursuant to Section 2(a)
or Section 2(b), the following provisions shall apply:

         The Company agrees to bear and to pay or cause to be paid all expenses
incident to the Company's performance of or compliance with this Exchange and
Registration Rights Agreement, including, without limitation, (a) all
Commission and any NASD registration and filing fees and expenses, (b) any fees
and expenses in connection with the qualification of Registrable Securities for
offering and sale under the State securities and blue sky laws referred to in
Section 3(c)(x) hereof, including reasonable fees and disbursements of counsel
for the placement or sales agent, if any, or underwriters, if any, in
connection with such qualifications, (c) all expenses relating to the
preparation, printing, distribution and reproduction of each registration
statement required to be filed hereunder, each prospectus included therein or
prepared for distribution pursuant hereto, each amendment or supplement to the
foregoing, and the certificates representing the Securities, (d) messenger and
delivery expenses, (e) fees and expenses of the Trustee under the Indenture and
of any escrow agent or custodian, (f) internal expenses (including, without
limitation, all salaries and expenses of the Company's officers and employees
performing legal or accounting duties), (g) fees, disbursements and expenses of
counsel and independent certified public accountants of the Company (including
the expenses of any opinions or "cold comfort" letters required by or incident
to such performance and compliance), (h) fees, disbursements and expenses of
any "qualified independent underwriter" engaged pursuant to Section 3(c)(xvii)
hereof, (i) fees, disbursements and expenses of one counsel for the holders of
Registrable





                                      -11-
<PAGE>   12

Securities retained in connection with a Shelf Registration, as selected by the
holders of at least a majority in aggregate principal amount of the Registrable
Securities being registered, and fees, expenses and disbursements of any other
persons, including special experts, retained by the Company in connection with
such registration (collectively, the "Registration Expenses"). To the extent
that any Registration Expenses are incurred, assumed or paid by any holder of
Registrable Securities or any placement or sales agent therefor or underwriter
thereof, the Company shall reimburse such person for the full amount of the
Registration Expenses so incurred, assumed or paid promptly after receipt of a
written request therefor. Notwithstanding the foregoing, the holders of the
Registrable Securities being registered shall pay all agency or brokerage fees
and commissions and underwriting discounts and commissions attributable to the
sale of such Registered Securities and the fees and disbursements of any
counsel or other advisors or experts retained by such holders (severally or
jointly), other than the counsel and experts specifically referred to above,
transfer taxes on resale of any of the Securities by such holders and any
advertising expenses incurred by or on behalf of such holders in connection
with any offers they may make.

5. Representations and Warranties.

         The Company represents and warrants to, and agrees with, each
Purchaser and each of the holders from time to time of Registrable Securities
that:

                 (a) Each registration statement covering Registrable
         Securities and each prospectus (including any preliminary or summary
         prospectus) contained therein or furnished pursuant to Section
         3(c)(ix) hereof and any further amendments or supplements to any such
         registration statement or prospectus, when it becomes effective or is
         filed with the Commission, as the case may be, and, in the case of an
         underwritten offering of Registrable Securities, at the time of the
         closing under the underwriting agreement relating thereto, will
         conform in all material respects to the requirements of the Securities
         Act and the Trust Indenture Act and any such registration statement
         and any amendment thereto will not contain an untrue statement of a
         material fact or omit to state a material fact required to be stated
         therein or necessary to make the statements therein not misleading and
         any such prospectus or any amendment or supplement thereto will not
         contain an untrue statement of a material fact or omit to state a
         material fact required to be stated therein or necessary to make the
         statements therein not misleading in light of the circumstances then
         existing; and at all times subsequent to the Effective Time of any
         such registration statement when a prospectus would be required to be
         delivered under the Securities Act, other than from (i) such time as a
         notice has been given to holders of Registrable Securities pursuant to
         Section 3(c)(vi)(F) hereof until (ii) such time as the Company
         furnishes an amended or supplemented prospectus pursuant to Section
         3(d) hereof, each such registration statement, and each prospectus
         (including any summary prospectus) contained therein or furnished
         pursuant to Section 3(c)(ix) hereof, as then amended or supplemented,
         will conform in all material respects to the requirements of the
         Securities Act and the Trust Indenture Act and will not contain an
         untrue statement of a material fact or omit to state a material fact
         required to be stated therein or necessary to make the statements
         therein not misleading in the light of the circumstances then
         existing; provided, however, that this representation and warranty
         shall not apply to any statements or omissions made in reliance upon
         and in conformity with information furnished in writing to the





                                      -12-
<PAGE>   13

         Company by a holder of Registrable Securities or any placement or
         sales agent therefor or underwriter thereof expressly for use therein.

                 (b) Any documents incorporated by reference in any prospectus
         referred to in Section 5(a) hereof, when they become or became
         effective or are or were filed with the Commission, as the case may
         be, will conform or conformed in all material respects to the
         requirements of the Securities Act or the Exchange Act, as applicable,
         and none of such documents will contain or contained an untrue
         statement of a material fact or will omit or omitted to state a
         material fact required to be stated therein or necessary to make the
         statements therein not misleading; provided, however, that this
         representation and warranty shall not apply to any statements or
         omissions made in reliance upon and in conformity with information
         furnished in writing to the Company by a holder of Registrable
         Securities expressly for use therein.

                 (c) The compliance by the Company with all of the provisions
         of this Exchange and Registration Rights Agreement and the
         consummation of the transactions herein contemplated will not conflict
         with or result in a breach of any of the terms or provisions of, or
         constitute a default under, any indenture, mortgage, deed of trust,
         loan agreement or other agreement or instrument to which the Company
         or any subsidiary of the Company is a party or by which the Company or
         any subsidiary of the Company is bound or to which any of the property
         or assets of the Company or any subsidiary of the Company is subject,
         nor will such action result in any violation of the provisions of the
         certificate of incorporation, as amended, or the by-laws of the
         Company or any statute or any order, rule or regulation of any court
         or governmental agency or body having jurisdiction over the Company or
         any subsidiary of the Company or any of their properties; and no
         consent, approval, authorization, order, registration or qualification
         of or with any such court or governmental agency or body is required
         for the consummation by the Company of the transactions contemplated
         by this Exchange and Registration Rights Agreement, except the
         registration under the Securities Act of the Registrable Securities,
         qualification of the Indenture under the Trust Indenture Act and such
         consents, approvals, authorizations, registrations or qualifications
         as may be required under State securities or blue sky laws in
         connection with the offering and distribution of the Registrable
         Securities.

                 (d) This Exchange and Registration Rights Agreement has been
         duly authorized, executed and delivered by the Company.

         6. Indemnification.

         (a) Indemnification by the Company. Upon the registration of the
Registrable Securities pursuant to Section 2 hereof, and in consideration of
the agreements of the Purchasers contained herein, and as an inducement to the
Purchasers to purchase the Securities, the Company shall, and it hereby agrees
to, (i) indemnify and hold harmless each of the holders of Registrable
Securities to be included in such registration, and each person who
participates as a placement or sales agent or as an underwriter in any offering
or sale of such Registrable Securities against any losses, claims, damages or
liabilities, joint or several, to which such holder, agent or underwriter may
become subject under the Securities Act or otherwise, insofar as such losses,
claims, damages or liabilities (or actions in respect thereof) arise out of or
are based upon an untrue statement or alleged untrue statement of a material
fact contained in any registration





                                      -13-
<PAGE>   14

statement under which such Registrable Securities were registered under the
Securities Act, or any preliminary, final or summary prospectus contained
therein or furnished by the Company to any such holder, agent or underwriter,
or any amendment or supplement thereto, or arise out of or are based upon the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading, and
(ii) reimburse such holder, such agent and such underwriter for any legal or
other expenses reasonably incurred by them in connection with investigating or
defending any such action or claim as such expenses are incurred; provided,
however, that the Company shall not be liable to any such person in any such
case to the extent that any such loss, claim, damage or liability arises out of
or is based upon an untrue statement or alleged untrue statement or omission or
alleged omission made in any such registration statement, or preliminary, final
or summary prospectus, or amendment or supplement thereto, in reliance upon and
in conformity with written information furnished to the Company by any holders
of Registrable Securities or any placement or sales agent thereof or
underwriter thereof expressly for use therein;

         (b) Indemnification by the Holders and any Agents and Underwriters.
The Company may require, as a condition to including any Registrable Securities
in any registration statement filed pursuant to Section 2 hereof and to
entering into any placement or underwriting agreement with respect thereto,
that the Company shall have received an undertaking reasonably satisfactory to
it from the holder of such Registrable Securities and from each placement agent
or underwriter named in any such placement agreement or underwriting agreement,
severally and not jointly, to (i) indemnify and hold harmless the Company, and
all other holders of Registrable Securities, against any losses, claims,
damages or liabilities to which the Company or such other holders of
Registrable Securities may become subject, under the Securities Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions
in respect thereof) arise out of or are based upon an untrue statement or
alleged untrue statement of a material fact contained in such registration
statement, or any preliminary, final or summary prospectus contained therein or
furnished by the Company to any such holder, agent or underwriter, or any
amendment or supplement thereto, or arise out of or are based upon the omission
or alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading, in each
case to the extent, but only to the extent, that such untrue statement or
alleged untrue statement or omission or alleged omission was made in reliance
upon and in conformity with written information furnished to the Company by
such holder, agent or underwriter expressly for use therein, and (ii) reimburse
the Company for any legal or other expenses reasonably incurred by the Company
in connection with investigating or defending any such action or claim as such
expenses are incurred; provided, however, that no such holder shall be required
to undertake liability to any person under this Section 6(b) for any amounts in
excess of the dollar amount of the proceeds to be received by such holder from
the sale of such holder's Registrable Securities pursuant to such registration.

         (c) Notices of Claims, Etc. Promptly after receipt by an indemnified
party under subsection (a) or (b) above of written notice of the commencement
of any action, such indemnified party shall, if a claim in respect thereof is
to be made against an indemnifying party pursuant to the indemnification
provisions of or contemplated by this Section 6, notify such indemnifying party
in writing of the commencement of such action; but the omission so to notify
the indemnifying party shall not relieve it from any liability which it may
have to any indemnified party other than under the indemnification provisions
of or contemplated by Section 6(a) or 6(b) hereof. In case





                                      -14-
<PAGE>   15

any such action shall be brought against any indemnified party and it shall
notify an indemnifying party of the commencement thereof, such indemnifying
party shall be entitled to participate therein and, to the extent that it shall
wish, jointly with any other indemnifying party similarly notified, to assume
the defense thereof, with counsel satisfactory to such indemnified party (who
shall not, except with the consent of the indemnified party, be counsel to the
indemnifying party), and, after notice from the indemnifying party to such
indemnified party of its election so to assume the defense thereof, such
indemnifying party shall not be liable to such indemnified party for any legal
expenses of other counsel or any other expenses, in each case subsequently
incurred by such indemnified party, in connection with the defense thereof
other than reasonable costs of investigation. No indemnifying party shall,
without the written consent of the indemnified party, effect the settlement or
compromise of, or consent to the entry of any judgment with respect to, any
pending or threatened action or claim in respect of which indemnification or
contribution may be sought hereunder (whether or not the indemnified party is
an actual or potential party to such action or claim) unless such settlement,
compromise or judgment (i) includes an unconditional release of the indemnified
party from all liability arising out of such action or claim and (ii) does not
include a statement as to or an admission of fault, culpability or a failure to
act by or on behalf of any indemnified party. No indemnifying party shall be
liable for the cost of any settlement effected by an indemnified party without
the written consent of such indemnifying party, which consent shall not be
unreasonably withheld. In no event shall any indemnifying party be liable for
the fees and expenses of more than one firm or counsel (except to the extent
that local counsel, in addition to such firm or counsel, is required for
effective representation) to represent all indemnified parties with respect to
a single action or separate but substantially similar actions in the same
jurisdiction arising out of the same general allegations.

         (d) Contribution. If for any reason the indemnification provisions
contemplated by Section 6(a) or Section 6(b) are unavailable to or insufficient
to hold harmless an indemnified party in respect of any losses, claims, damages
or liabilities (or actions in respect thereof) referred to therein, then each
indemnifying party shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages or liabilities
(or actions in respect thereof) in such proportion as is appropriate to reflect
not only (i) the relative benefits received by the holders of the Registrable
Securities, on the one hand, and any agents or underwriters, on the other, from
any offering or sale of the Registrable Securities, but also (ii) the relative
fault of the indemnifying party and the indemnified party in connection with
the statements or omissions which resulted in such losses, claims, damages or
liabilities (or actions in respect thereof), as well as any other relevant
equitable considerations. The relative benefits received by the holders of the
Registrable Securities on the one hand and any agents or underwriters on the
other shall be deemed to be in the same proportion as the total net proceeds
from any offering or sale thereof (before deducting expenses) received by such
holders bear to the total discounts and commissions received by any such agents
or underwriters with respect to such offer or sale. The relative fault of such
indemnifying party and indemnified party shall be determined by reference to,
among other things, whether the untrue or alleged untrue statement of a
material fact or omission or alleged omission to state a material fact relates
to information supplied by such indemnifying party or by such indemnified
party, and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission. The parties
hereto agree that it would not be just and equitable if contributions pursuant
to this Section 6(d) were determined by pro rata allocation (even if the
holders or any agents or underwriters or all of them were treated as one entity
for such purpose) or by any other method of allocation





                                      -15-

which does not take account of the equitable considerations referred to in this
Section 6(d). The amount paid or payable by an indemnified party as a result of
the losses, claims, damages, or liabilities (or actions in respect thereof)
referred to above shall be deemed to include any legal or other fees or
expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim. Notwithstanding the
provisions of this Section 6(d), no holder shall be required to contribute any
amount in excess of the amount by which the dollar amount of the proceeds
received by such holder from the sale of any Registrable Securities (after
deducting any fees, discounts and commissions applicable thereto) exceeds the
amount of any damages which such holder has otherwise been required to pay by
reason of such untrue or alleged untrue statement or omission or alleged
omission, and no underwriter or agent shall be required to contribute any
amount in excess of the amount by which the total price at which the
Registrable Securities placed or underwritten by it and distributed to the
public were offered to the public exceeds the amount of any damages which such
underwriter or agent has otherwise been required to pay by reason of such
untrue or alleged untrue statement or omission or alleged omission. No person
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Securities Act) shall be entitled to contribution from any person who was
not guilty of such fraudulent misrepresentation. The holders' and any
underwriters' or agent's obligations in this Section 6(d) to contribute shall
be several in proportion to the principal amount of Registrable Securities
registered, underwritten or placed, as the case may be, by them and not joint.

         (e) The obligations of the Company under this Section 6 shall be in
addition to any liability which the Company may otherwise have and shall
extend, upon the same terms and conditions, to each officer, director and
partner of each holder, agent and underwriter and each person, if any, who
controls any holder, agent or underwriter within the meaning of the Securities
Act; and the obligations of the holders and any agents or underwriters
contemplated by this Section 6 shall be in addition to any liability which the
respective holder, agent or underwriter may otherwise have and shall extend,
upon the same terms and conditions, to each officer and director of the Company
(including any person who, with his consent, is named in any registration
statement as about to become a director of the Company) and to each person, if
any, who controls the Company within the meaning of the Securities Act.

         7. Underwritten Offerings.

         (a) Selection of Underwriters. If any of the Registrable Securities
covered by the Shelf Registration are to be sold pursuant to an underwritten
offering, the managing underwriter or underwriters thereof shall be designated
by the holders of at least a majority in aggregate principal amount of the
Registrable Securities to be included in such offering, provided that such
designated managing underwriter or underwriters is or are reasonably acceptable
to the Company.

         (b) Participation by Holders. Each holder of Registrable Securities
hereby agrees with each other such holder that no such holder may participate
in any underwritten offering hereunder unless such holder (i) agrees to sell
such holder's Registrable Securities on the basis provided in any underwriting
arrangements approved by the persons entitled hereunder to approve such
arrangements and (ii) completes and executes all questionnaires, powers of
attorney, indemnities, underwriting agreements and other documents reasonably
required under the terms of such underwriting arrangements.

         (c) Consolidated Earnings Statements. In the event of an underwritten
offering, the Company agrees to make generally available to its securityholders
as soon as practicable, but in any event not later than eighteen months after
the effective date of the applicable registration statement (as defined in Rule
158(c) under the Act), a consolidated earnings statement of the Company
complying with Section 11(a) of the Act and the rules and regulations of the
Commission thereunder (including, at the option of the Company, Rule 158 under
the Act).

         8. Rule 144.

         The Company covenants to the holders of Registrable Securities that to
the extent it shall be required to do so under the Exchange Act, the Company
shall timely file the reports required to be filed by it under the Exchange Act
or the Securities Act (including, but not limited to, the reports under Section
13 and 15(d) of the Exchange Act referred to in subparagraph (c)(1) of Rule 144
adopted by the Commission under the Securities Act) and the rules and
regulations adopted by the Commission thereunder, and shall take such further
action as any holder of Registrable Securities may reasonably request, all to
the extent required from time to time to make Rule 144 available to such holder
for the sale of Registrable Securities without registration under the
Securities Act within the limitations of the exemption provided by Rule 144
under the Securities Act, as such Rule may be amended from time to time, or any
similar or successor rule or regulation hereafter adopted by the Commission.
Upon the request of any holder of Registrable Securities in connection with
that holder's sale pursuant to Rule 144, the Company shall deliver to such
holder a written statement as to whether it has complied with such
requirements.

         9. Miscellaneous.

would be no adequate remedy at law if any party fails to perform any of its
obligations hereunder and that each party may be irreparably harmed by any such
failure, and accordingly agree that each party, in addition to any other remedy
to which it may be entitled at law or in equity, shall be entitled to compel
specific performance of the obligations of any other party under this Exchange
and Registration Rights Agreement in accordance with the terms and conditions
of this Exchange and Registration Rights Agreement, in any court of the United
States or any State thereof having jurisdiction.

         (c) Notices. All notices, requests, claims, demands, waivers and other
communications hereunder shall be in writing and shall be deemed to have been
duly given when delivered by hand, if delivered personally or by courier, or

postage prepaid, return receipt requested) as follows: If to the Company, to it
at 425 Woods Mill South, Town & Country, Missouri 63017, Attention: David L.
Solomon and if to a holder, to the address of such holder set forth in the
