THE COMPANY

GENERAL

The Company is a facilities-based provider of technologically advanced,
high-bandwidth, fiber optic communications infrastructure to carrier and
corporate/government customers. The Company is expanding its existing network to
encompass approximately 229,000 fiber miles or 643 route miles, concentrated in
the northeastern United States, a market which the Company believes is
characterized by significant demand for and limited supply of fiber optic
capacity. The fiber infrastructure leased by MFN to its customers provides
high-bandwidth capacity for customers that seek to establish secure
communications networks for the transmission of large amounts of voice, data and
video. For example, a pair of MFN fiber optic strands can transmit up to 8.6
gigabits of data per second or the equivalent of approximately 129,000
simultaneous voice conversations.

The Company tailors the amount of fiber capacity leased to the needs of its
customers. Certain customers that lease fiber optic capacity from the Company
connect their own transmission equipment to the leased fiber, thereby obtaining
a fixed-cost, secure communications alternative to the metered communications
services offered by traditional providers. Other customers that require lesser
amounts of transmission capacity will have the option to lease such broadband
capacity on the Company's network, whereby the Company effectively divides a
single strand of fiber into multiple smaller communications channels. The
Company believes that it will have installation, operating and maintenance cost
advantages per fiber mile relative to its competitors because MFN installs as
many as 432 fibers per route mile as compared to a generally lower number of
fibers in existing competitive networks.

3
<PAGE>
See "Business -- Build-out of Networks," and "Risk Factors -- Risks Associated
with Growth Strategy." The Company's NY Network supports a self-healing SONET
architecture that minimizes the risk of downtime in the event of a fiber cut and
provides MFN's customers with high security and reliability. It is expected that
the Company's other Intra-City Networks will also support a self-healing SONET
architecture. Most of the Company's fiber is installed inside high density
polyethylene conduit to protect the cable and, where practicable, MFN installs
additional unused conduits to accommodate future network expansion.

MFN is focused on providing its broadband communications infrastructure to
two main customer groups: communications carriers and corporate/government
customers located in selected Tier I markets. Carrier customers targeted by the
Company include a broad range of communications companies such as incumbent
local exchange carriers ("ILECs"), competitive local exchange carriers
("CLECs"), long distance companies/interexchange carriers ("IXCs"), paging,
cellular and PCS companies, cable companies, and Internet service providers
("ISPs"). These carrier customers typically would lease fiber optic capacity
with which they would develop their own communications networks as a low-cost
alternative to building their own infrastructure or purchasing metered services
from ILECs or CLECs. The Company's corporate and government customers would
typically lease fiber optic infrastructure and other broadband services on a
point-to-point basis for high-bandwidth, secure voice and data networks. The
Company believes that it will be well-positioned to penetrate the corporate and
government markets since it plans to continue to install most of its fiber in
Tier I markets. See "Business -- Customers."

MFN intends to capitalize on the increasing demand for high-bandwidth
communications services and the limited supply of transmission capacity. The
Company believes that demand for the broadband communications infrastructure
afforded by its network will continue to increase as a result of the following
factors: (i) the rapid growth of communications traffic, such as data traffic
which industry research indicates is growing by 35% annually; (ii) the large
number of new carriers which will require significant transmission capabilities
in all sectors of the communications industry, due in large part to industry
deregulation facilitated by the Telecommunications Act of 1996 (the "1996 Act"),
(iii) the fact that the RBOCs will likely need to upgrade to fiber optic
networks with infrastructure similar to the Company's; and (iv) the advent of
new communications services requiring large amounts of transmission capacity,
such as intranet and video services. According to an industry report, the total
1995 market for communications services in the United States was approximately
$282 billion and is expected to grow to approximately $457 billion by the year
2000. In addition, the Company believes there will be increased demand for its
infrastructure due to its ability to offer fixed-cost pricing which is generally
more economical for high volume users than traditional usage-based pricing.

On April 30, 1997, Metromedia Company, a partnership owned and controlled by
John W. Kluge and Stuart Subotnick ("Metromedia"), and certain of its affiliates
made a substantial equity investment in the Company (the "Metromedia
Investment"). Metromedia and its partners own all of the outstanding shares of
Class B Common Stock which is entitled to 10 votes per share and to vote
separately to elect at least 75% of the members of the Board of Directors ("the
Board"). As a result, Metromedia and its partners own and control approximately
25% of the common equity of the Company (on a fully diluted basis) and
approximately 76.4% of the outstanding voting power (on a fully diluted basis).
Metromedia and its predecessor have successfully invested in and operated
numerous businesses in the communications industry, including cellular, paging,
long distance and media companies. In connection with the Metromedia Investment,
John W. Kluge and Stuart Subotnick, who bring considerable management and
corporate governance experience to the Company, joined MFN's Board of Directors.
See "Certain Relationships and Related Transactions."

BUSINESS STRATEGY

The Company's objective is to become the preferred facilities-based provider
of broadband communications infrastructure to communications carriers,
corporations and government agencies, primarily in the northeastern United
States. The following are the key elements of MFN's strategy to achieve this
objective:

ESTABLISH THE COMPANY AS THE PREFERRED CARRIERS' CARRIER OF BROADBAND
COMMUNICATIONS INFRASTRUCTURE.

MFN leases broadband communications infrastructure on a fixed-cost basis to
various communications carriers, thus enabling them to compete in markets which
were previously difficult to penetrate due to limited and/or costly access to
high-bandwidth communications infrastructure. Specifically, the Company plans to
lease local transmission capacity within its target Tier I markets thereby
enabling its carrier customers to bypass the ILECs and CLECs. The Company
believes that it is currently the only provider of local transmission
infrastructure on a fixed-cost basis. Additionally, the Company plans to lease
capacity on its high-bandwidth, long-haul Inter-City Network (as defined herein)
to provide seamless connectivity between its various Intra-City Networks (as
defined herein). The Company's fixed-cost, long-term contracts allow its carrier
customers to access certain Tier I markets without incurring the high capital
expenditures and long lead times usually associated with building their own
networks. Carriers may be more likely to lease capacity from MFN rather than
from a competitor since MFN currently has no plans to offer communications
infrastructure services on a metered basis, choosing instead to position itself
as a non-competing provider of infrastructure alternatives for IXCs, ILECs,
CLECs, etc. See "Business -- Customers."

POSITION THE COMPANY AS THE PREFERRED PROVIDER OF BROADBAND COMMUNICATIONS
INFRASTRUCTURE TO CORPORATE AND GOVERNMENT CUSTOMERS.

The Company's fiber optic network is expected to serve Tier I markets in
which there are a large number of corporations and government agencies that the
Company believes have significant demand for communications capacity which has
not been satisfied. These customers typically lease broadband communications
infrastructure from the Company on a point-to-point basis, creating secure
networks for voice, video or data communications. Customers with significant
transmission needs or who require a high degree of security are potential
candidates for leasing MFN's fiber. Customers seeking lesser amounts of
broadband transmission capacity will have the option of leasing smaller amounts
of capacity from the Company. By providing leased capacity on a fixed-cost
rather than a metered basis, MFN's network, as currently planned, will be more
economical for MFN's corporate and government customers, while also providing
enhanced reliability and security. See "Business --Customers."

STRENGTHEN MFN'S COMPETITIVE POSITION BY EXPANDING THE MFN NETWORK.

The Company seeks to enhance its attractiveness as a communications provider
by enlarging its network according to a three-part plan: (i) expanding the NY
Network to increase coverage of the New York/New Jersey metropolitan area to
approximately 61,000 fiber miles covering 179 route miles, (ii) constructing
fiber optic intra-city telecommunications networks in Washington, D.C., Chicago
and Philadelphia (the "Intra-City Networks") and (iii) constructing a fiber
optic backbone between New York City and Washington, D.C. (the "Inter-City
Network") to link certain of its Intra-City Networks. Once completed, MFN's
domestic fiber optic network infrastructure, as currently planned, will consist
of approximately 229,000 fiber miles covering 643 route miles (the "MFN
Network").

UTILIZE STRATEGIC RELATIONSHIPS TO EXPAND THE REACH OF THE MFN NETWORK.

Another part of MFN's strategy is to enter into agreements with other
communications companies to expand the reach of the MFN Network. MFN has signed
a letter of cooperation with a leading global

5
<PAGE>
voice and data communications provider in the United Kingdom. A definitive
agreement, if entered into, would expand the reach of MFN's network to the
United Kingdom and provide seamless connectivity between two leading financial
centers, New York City and London. The Company believes that its presence in
Tier I markets will continue to provide similar partnering opportunities. The
Company will continue to evaluate opportunities, including potential fiber
swaps, along specific additional routes in order to speed the build-out of the
MFN Network and reduce costs.

CREATE A LOW COST POSITION.

The Company believes it will be able to establish a low cost position
relative to its competitors primarily for the following reasons: (i) the Company
currently installs trunks of up to 432 fibers per route mile, which the Company
believes is substantially more fiber than many of its competitors install,
thereby reducing the per fiber mile cost to construct and operate the MFN
Network, (ii) the Company owns a newly-constructed network with advanced fiber
optic technology which offers operating and maintenance cost advantages, (iii)
the Company believes that certain of its rights-of-way and franchises are
valuable assets that will be costly and difficult for others to procure in the
future and (iv) MFN, where practicable, installs spare conduit which will allow
for expanded fiber optic capacity at a cost significantly below the cost of new
construction. The Company's low cost position will allow it to remain price
competitive with other providers of fiber optic infrastructure and to lease its
fiber infrastructure at a price which customers will find more attractive than
the cost of constructing their own networks.

INSTALL A TECHNOLOGICALLY ADVANCED NETWORK.

The Company believes that the advanced technical characteristics of its
network will allow it to provide high levels of reliability, security and
capacity that its target customers typically demand. The NY Network is, and
future extensions of the Intra-City Networks will be, capable of supporting a
SONET ring architecture, which prevents interruption in service to its clients
by instantaneously rerouting traffic in the event of a fiber cut. The Company
will also continuously monitor and maintain high quality control of its network
on a 24-hour basis through its network operations center. The Company's network
is capable of using the highest commercially available capacity transmission
(OC-192) and thereby can support advanced, capacity-intensive data applications
such as Frame Relay, ATM, multimedia and Internet-related applications.

BUILD ON MANAGEMENT EXPERIENCE.

The Company's management team and Board of Directors include individuals
with communications industry expertise and extensive experience in network
design, construction, operations and sales. MFN's Chief Executive Officer and
founder, Stephen A. Garofalo, has approximately 25 years of experience in the
cable installation business, having managed the installation of over one half
billion dollars in electrical and communications cable in New York City. In
April 1997, the Company hired Howard Finkelstein as President and Chief
Operating Officer. From 1984 to 1993, Mr. Finkelstein served as President of
Metromedia Communications Corporation, Metromedia's long distance telephone
enterprise, until its merger with WorldCom, Inc. in 1993. In his most recent
position, Mr. Finkelstein was the Chief Operating Officer and an Executive Vice
President of Metromedia International Telecommunications, Inc., an international
telecommunications and media company. He has also served in various capacities
at Metromedia and its affiliated companies over a period of 16 years. The
Company also expects to benefit from the communications industry expertise and
corporate governance experience of John W. Kluge and Stuart Subotnick, members
of its Board of Directors. See "Certain Relationships and Related Transactions."

MFN is a Delaware corporation and the principal executive offices of the
Company are located at 110 East 42nd Street, Suite 1502, New York, New York
10017. The Company's telephone number at such address is (212) 687-9177.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

This Prospectus includes "forward-looking" statements (as such term is
defined in the Private Securities Litigation Reform Act of 1995), including
statements regarding, among other items, (i) the Company's growth strategy, (ii)
the Company's intention to expand its fiber optic network to other markets and
(iii) the Company's intention to market its network to new customers. These
forward-looking statements are based largely on the Company's expectations and
are subject to a number of risks and uncertainties, certain of which are beyond
the Company's control. Actual results could differ materially from these
forward-looking statements as a result of the facts described in "Prospectus
Summary," "Risk Factors" and "Business" including, among others, (i) changes in
the competitive marketplace, including the introduction of new technologies or
strategic and/or pricing changes by the Company's competitors and (ii) changes
in the economy. Other factors which may materially affect actual results
include, among others, the following: general economic and business conditions;
industry capacity; uncertainty regarding and changes in customer preferences;
demographic changes; competition; changes in methods of marketing and
technology; changes in political, social and economic conditions; and regulatory
factors and various other factors beyond the Company's control. The Company
undertakes no obligation to publicly update or revise any forward-looking
statements, whether as a result of new information, future events or otherwise.
In light of these risks and uncertainties, there can be no assurance that the
forward-looking information contained in this Prospectus will in fact transpire.

RISK FACTORS

IN ADDITION TO THE OTHER INFORMATION AND FINANCIAL DATA SET FORTH ELSEWHERE
IN THIS PROSPECTUS, THE FOLLOWING RISK FACTORS SHOULD BE CONSIDERED CAREFULLY IN
EVALUATING THE COMPANY AND ITS BUSINESS BEFORE PURCHASING THE SHARES OF CLASS A
COMMON STOCK OFFERED HEREBY.

LIMITED HISTORY OF OPERATIONS; NET LOSSES AND NEGATIVE CASH FLOW FROM
OPERATIONS; EXPECTED FUTURE NET LOSSES AND NEGATIVE CASH FLOW FROM OPERATIONS

The Company was formed in April 1993 and has a limited operating history,
with a limited number of customers as of June 30, 1997. Accordingly, prospective
investors have limited historical financial information upon which to base an
evaluation of the Company's performance and an investment in shares of Class A
Common Stock. The Company's prospects must be considered in light of the risks,
expenses and difficulties frequently encountered by companies in their early
stage of development.

Since inception, the Company has not generated significant revenue, has
incurred substantial net losses and has never generated positive cash flow from
operations. The Company had net losses of $10.4 million, $4.3 million, $0.9
million, and $0.2 million for the periods ended December 31, 1996, 1995, 1994,
and 1993 and a net loss of $20.0 million for the six months ended June 30, 1997.
There can be no assurance that the Company will be able to achieve or sustain
profitability or positive cash flow in the future.

The Company believes that losses will continue while the Company
concentrates on the development and construction of additional fiber optic
networks and until its networks have established a sufficient revenue-generating
customer base. The Company will also incur losses during the initial start-up
phases of the services that it may provide. There can be no assurance that an
adequate revenue base will be established or that these services will generate
profitability or positive cash flow. Continued losses and negative cash flow may
prevent the Company from pursuing its strategies for growth.

RISKS ASSOCIATED WITH GROWTH STRATEGY; MANAGEMENT OF EXPANSION

The future of the Company depends, to a large extent, on its ability to
implement its business strategy and proposed expansion, without which the
Company would be unable to create the new business and revenue opportunities
described in this Prospectus. The proposed expansion (including

9
<PAGE>
the development of the Intra-City Networks, the Inter-City Network and the
proposed expansion to additional areas including the United Kingdom) requires
that the Company obtain access to markets, design fiber network backbone routes,
install facilities, acquire rights-of-way and building access, obtain required
governmental authorizations and permits and continue to implement and improve
its operational, financial and accounting systems, all in a timely manner at
reasonable costs and on conditions acceptable to the Company. Successful
implementation will depend on numerous factors beyond the Company's control,
including economic, competitive and other conditions and uncertainties, the
ability to obtain licenses, franchises and rights-of-way on reasonable terms and
conditions and hire and retain qualified management personnel. In addition,
construction of future networks entails significant risks, including
management's ability to effectively control and manage such projects, shortages
of materials or skilled labor, unforeseen engineering, environmental or
geological problems, work stoppages, weather interference, floods and
unanticipated cost increases. No assurance can be given that the budgeted costs
of the Company's current and future projects will not be exceeded or that any
such projects will commence operations within the contemplated schedules, if at
all. The failure to obtain necessary licenses, permits and authorizations could
prevent or delay the completion of construction of all or part of such networks
or increase completion costs. Moreover, no assurance can be given that the
Company will be successful in implementing its business strategy and in managing
expansion effectively, on time or at all.

The Company will need to expand its marketing efforts and staff to handle
future marketing and sales requirements. Failure to obtain significant,
widespread commercial and public acceptance of its networks and access to
sufficient buildings in a market could jeopardize the Company's viability in
that market. There can be no assurance that the Company will be able to secure
customers for the commercial use of its proposed networks or access to such
buildings in each market.

The Company's ability to implement its business plan is, to a significant
degree, dependent upon the Company's ability to secure a market for its leased
fiber capacity and obtain and maintain contractual and other relationships with
communications carriers and corporate and government customers. The practice of
leasing dark fiber is not widespread and there can be no assurance that such a
market will develop or that the Company will be able to enter into contracts,
comply with the terms of such contracts or maintain relationships with
communications carriers and corporate and government customers, that any such
contracts or relationships will be on economically favorable terms or that such
communications carriers and corporate and government customers will not choose
to compete against, rather than cooperate with, the Company. The Company's
inability to enter into contracts, comply with the terms of such contracts or
maintain relationships with these constituencies would materially and adversely
affect the Company's business, financial condition and results of operations.

The Company cannot predict whether providing services to governments will
evolve into a significant market. Existing rights-of-way are typically
controlled by governments and are often used to create leverage in "shared
resources projects" whereby the government obtains communications capacity in
exchange for providing a private communications carrier access to government
controlled rights-of-way for fiber installation. In addition, governments often
build their own communications infrastructure because they already control the
necessary rights-of-way. Accordingly, there can be no assurance that the market
for government customers will develop to any significant extent.

A number of the Company's current contracts to supply leased fiber capacity
permit the lessee to terminate such contracts and/or provide for liquidated
damages if the Company does not supply such fiber capacity by a specified time.
Certain of these contracts are currently terminable on this basis. The
termination of any such contracts could adversely affect the Company's business,
financial condition and results of operations.

10
<PAGE>
The Company may expand the range of services that it offers. Such plans may
include assisting customers with the integration of their leased dark fiber with
appropriate electronic and optronic equipment by facilitating the involvement of
third party suppliers, vendors and contractors. There can be no assurance that a
market will develop for new services offered by the Company, that the Company's
implementation of the services will be technically or economically feasible,
that the Company will be able to successfully develop or market them or that the
Company will be able to operate and maintain its new services profitably.

NEED FOR ADDITIONAL FINANCING

The net proceeds from the Offerings will not be sufficient to enable the
Company to complete the build-out of its planned fiber optic network and meet
its long-term business strategies. The completion of the Company's planned fiber
optic communications networks will require substantial capital investment. The
Company's ability to arrange financing and the cost of such financing are
dependent upon numerous factors, including general economic and capital market
conditions, conditions in the communications market, regulatory developments,
credit availability from banks or other lenders, investor confidence in the
industry and the Company, the success of the Company's fiber optic
communications networks, and provisions of tax and securities laws that are
conducive to raising capital. There can be no assurance that financing for the
expansion of the Company's fiber optic communications networks will be available
to the Company on acceptable terms in the future or that, if the form of any
such future financing is through the issuance and sale of equity securities,
investors in the Offerings will not be diluted.

COMPETITIVE INDUSTRY

The Company faces substantial competition from ILECs, which currently
dominate their local telecommunications markets, and CLECs, most of which have
greater financial, research and development and other resources than the
Company. In addition to ILECs and CLECs, potential competitors capable of
offering services similar to those offered by the Company include IXCs, other
facilities-based communications service providers, cable television companies,
electric utilities, microwave carriers, satellite carriers, wireless telephone
system operators and large end-users with private networks. There can be no
assurance that such entities will not compete with the Company. See "Business--
Competition."

Various communications carriers already own fiber optic cables as part of
their telecommunications networks. Accordingly, any of these carriers, some of
which already have franchise agreements with the City of New York and
substantially greater resources and more experience than the Company, could
compete directly with the Company in the market for leasing fiber capacity,
provided that these competitors are willing to offer this capacity to all their
customers. In addition, the Company's franchise agreement with the City of New
York is not exclusive. Potential competitors with greater resources and more
experience than the Company could enter into franchise agreements with the City
of New York and compete directly with the Company.

In addition, some communications carriers and local cable companies have
extensive networks in place that could be upgraded to fiber optic cable, as well
as numerous personnel and substantial resources to undertake the requisite
construction to so equip their networks. To the extent that communications
carriers and local cable companies decide to equip their networks with fiber
optic cable, they are potential significant competitors of the Company.

There is no reason to believe that other companies will not choose to
compete with the Company in any market, inside or outside of New York City, by
leasing fiber capacity (including dark fiber) to the Company's targeted
customers. Any such additional competition could materially adversely affect the
Company's business, financial condition and results of operations.

11
<PAGE>
EXTENSIVE REGULATION

Existing and future governmental regulations will greatly influence the
viability of the Company. However, the Company cannot predict the future
regulatory status of its business.

FEDERAL

Federal telecommunications law directly shapes the market in which the
Company competes. Consequently, undesirable regulatory changes could adversely
affect the Company's business, financial conditions and results of operations.

Federal telecommunications law imposes special legal requirements on "common
carriers." The Company believes that it does not provide any services on a
common carrier basis and therefore is not subject to the common carrier
regulations of the Federal Communications Commission ("FCC") or to the common
carrier provisions of the Communications Act of 1934 ("Communications Act"), as
amended. Federal telecommunications law also imposes special legal requirements
on "telecommunications carriers." Presently, the law is unclear as to whether a
provider of fiber capacity or dark fiber like the Company is a
"telecommunications carrier". The FCC has been asked to clarify the status of
dark fiber providers, and if the agency decides that such companies are
telecommunications carriers, then the Company would be subject to certain
additional regulatory requirements. The extent to and manner in which the
Company provides telecommunications services will influence whether it is
subject to FCC regulation as a common carrier and/or a telecommunications
carrier, like the ILECs and the CLECs. In such a case, and particularly if the
Company's fiber capacity leasing business also becomes subject to regulation,
the Company may lose the competitive advantages associated with being a
relatively unregulated entity and this could have an adverse effect on its
results of operations. Presently, however, the Company is relatively
unencumbered by federal telecommunications laws. This competitive advantage may
be eroded at any time if the Company were to begin offering telecommunications
services on a common carrier basis or if any of the regulatory rules or policies
applicable to the Company were to change.

ILECs, CLECs and IXCs are subject to various federal telecommunications
laws. Accordingly, federal telecommunications law may affect the Company's
business by virtue of the inter-relationships that exist among the Company and
many of these regulated telecommunications entities. For example, the FCC
recently issued an order requiring, among other things, that access fees charged
to IXCs, which previously amounted to more than just the recovery of the RBOCs'
investment in fixed assets, shift from being usage driven to a fixed flat cost
structure. While it is not possible to predict the precise effect this change
will have on the Company's business or financial condition, the reforms will
reduce access charges paid by IXCs, likely eliminating one of the principal
disincentives for use of ILEC and CLEC facilities by IXCs, which could have a
material adverse effect on the use of the Company's fiber optic
telecommunications networks by IXCs.

STATE

In arbitrating interconnection agreements under the 1996 Act between ILECs
and their potential competitors, some state commissions have considered whether
dark fiber should be considered an unbundled network element. For example, the
New York Public Service Commission determined that it would not require NYNEX
Corporation ("NYNEX") to provide dark fiber as an unbundled network element.
State commissions, including those in Florida, Maryland, North Carolina, and
Virginia, also have either refused to require the ILECs to offer dark fiber to
competitors, or have stated that the issue would be addressed at a later time.
On the other hand, state commissions in Illinois, Massachusetts, Arizona,
Georgia, Minnesota, Ohio, Oregon and Tennessee have found dark fiber to be a
network element and required the ILECs to offer it on an unbundled basis to
CLECs. There can be no assurance

12
<PAGE>
that these requirements, and the associated pricing methodologies, where
applicable, will not reduce the demand for dark fiber provided by the Company.

The Company believes that it is not subject to regulation as a
telecommunications carrier by state commissions in Illinois, New York,
Pennsylvania, or the District of Columbia. However, whether a provider of fiber
capacity is subject to the jurisdiction of regulatory commissions in these
states is uncertain. In addition, the extent to and manner in which the Company
provides communications services will influence whether it is subject to the
same state regulations that are imposed on ILECs and CLECs. If the Company does
become subject to state regulation it could lose the competitive advantages
associated with being a relatively unregulated entity. There can be no assurance
that a state commission will not exercise jurisdiction over the Company's
business. State regulation affects market conditions for the services of the
Company and its customers, and thus affects the Company's business.

LOCAL

In addition to federal and state laws, local governments exercise legal
authority that may impact the Company's business. For example, local
governments, such as the City of New York, typically retain the ability to
license public rights-of-way, subject to the limitation that local governments
may not prohibit persons from providing telecommunications services. Local
authorities affect the timing and costs associated with the Company's use of
public rights-of-way. These regulations may have an adverse effect on the
Company's business.

INTERNATIONAL

Various regulatory requirements and limitations also will influence the
Company's business as it attempts to enter international markets.

Domestically, the FCC imposes various regulations on international
telecommunications service providers. For example, international common carriers
are required to obtain authorization under Section 214 of the Communications Act
prior to initiating international telecommunications services. Furthermore, many
international telecommunications services are subject to FCC restrictions such
as on the resale of telecommunications capacity. The exact nature of the
applicable restrictions is uncertain because many of the restrictions are being
revised by the FCC and because the Company has not fully determined its
international business strategy.

The Company is currently negotiating an agreement with a foreign firm that
contemplates jointly acquiring and selling international, facilities-based
telecommunications capacity between the U.S. and the United Kingdom.
International telecommunications services are subject to separate regulations in
the United Kingdom. Failure to obtain an appropriate domestic or foreign license
for international service, or the revocation of a license, could have a material
adverse effect on the future operations of the Company.

RISK OF CANCELLATION OR NON-RENEWAL OF FRANCHISES, LICENSES OR PERMITS

The Company operates its NY Network based on a franchise agreement entered
into between the Company and the City of New York on December 20, 1993 (the "NYC
Franchise Agreement"). Both the City of New York and the Company have the right,
at any time after December 2000, upon six months' notice, to renegotiate certain
terms of the NYC Franchise Agreement, including the annual franchise fee payable
by the Company, based on changes in technological, regulatory or market
conditions which may occur after the effective date of the NYC Franchise
Agreement. In the event either party calls for renegotiation, both the City of
New York and the Company are required to negotiate any such changes in good
faith. In the event an agreement cannot be reached upon any such renegotiation,
the NYC Franchise Agreement will be subject to early termination on a date which
would be one half of the number of days between the date of the notice to
renegotiate and January 1, 2009. Termination of the

13
<PAGE>
NYC Franchise Agreement would have a material adverse effect on the Company's
business, results of operations and financial condition. See
"Business--Franchise, License and Related Agreements--New York City Franchise
Agreement."

The Company's NY Network relies upon, and its planned expansions into Long
Island and Westchester County will rely upon, right-of-way agreements between
the Company and NYNEX and its subsidiary, Empire City Subway Company (Ltd.)
("ECS"). The current agreements are subject to termination at any time without
cause upon three months' notice. In case of termination, the Company may be
required to remove its fiber optic cable from the conduits or poles of NYNEX.
Such termination would have a material adverse effect on the Company's business,
financial condition and results of operations. In addition, the Company will
require additional licenses, right-of-way agreements and permits in order to
expand its NY Network and build new networks. There can be no assurance that the
Company will be successful in obtaining acceptable right-of-way agreements. Some
of these agreements may be short-term or revocable at will, and there can be no
assurance that the Company will have continued access to existing rights-of-way
and franchises after their expiration or termination. If any of these agreements
were terminated or could not be renewed and the Company was forced to remove its
fiber optic cable from under the streets or abandon its NY Network, such
termination would have a material adverse effect on the Company's business,
results of operations and financial condition. 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 strategy on acceptable terms.

RAPID TECHNOLOGICAL CHANGE

The communications industry is subject to rapid and significant changes in
technology that could materially affect the continued use of fiber optic cable.
The effect of technological changes on the business of the Company cannot be
predicted, and there can be no assurance that technological changes in the
communications industry will not have a material adverse effect on the Company's
business, results of operations and financial condition.

RISKS ASSOCIATED WITH INTERNATIONAL OPERATIONS

There are certain risks inherent in doing business on an international
level, including regulatory limitations restricting or prohibiting the provision
of the Company's services, unexpected changes in regulatory requirements,
tariffs, customs, duties and other trade barriers, difficulties in staffing and
managing foreign operations, longer payment cycles, problems in collecting
accounts receivable, political risks, fluctuations in currency exchange rates,
technology export and import restrictions or prohibitions, delays from customs
brokers or government agencies, and potentially adverse tax consequences
resulting from operating in multiple jurisdictions with different tax laws.
Furthermore, international rates charged to customers are likely to decrease in
the future for a variety of reasons, including increased competition between
existing carriers, new entrants into geographic markets in which the Company
operates or intends to operate and additional strategic alliances or joint
ventures among large international carriers that facilitate targeted pricing and
cost reductions. See "--Extensive Regulation-- International" and
"Business--Regulation."

RISKS ASSOCIATED WITH ACQUISITIONS, INVESTMENTS AND STRATEGIC ALLIANCES

The Company may, in the future, acquire or engage in efforts to acquire
customer bases and businesses from, make investments in, or enter into strategic
alliances with, companies which have customer bases, switching capabilities or
existing networks in the Company's current markets or in areas into which the
Company intends to expand the MFN Network. Although the Company is currently
evaluating several potential strategic opportunities, it does not have any
present definitive commitment or agreement with respect to any acquisition,
investment, strategic alliance or related effort. Any future

14
<PAGE>
acquisitions, investments, strategic alliances or related efforts will be
accompanied by the risks such as the difficulty of identifying appropriate
acquisition candidates, the difficulty of assimilating the operations of the
respective entities, the potential disruption of the Company's ongoing business,
the inability of management to capitalize on the opportunities presented by
acquisitions, investments, strategic alliances or related efforts, the failure
to successfully incorporate licensed or acquired technology and rights into the
Company's services, the inability to maintain uniform standards, controls,
procedures and policies and the impairment of relationships with employees and
customers as a result of changes in management. There can be no assurance that
the Company would be successful in overcoming these risks or any other problems
encountered with such acquisitions, investments, strategic alliances or related
efforts. See "--Risks Associated with Growth Strategy; Management of Expansion"
and "Business--Business Strategy--Utilize Strategic Relationships to Expand the
Reach of the MFN Network."

RELIANCE ON KEY PERSONNEL; CONCENTRATION OF VOTING POWER BY PRINCIPAL
STOCKHOLDERS; ANTI-TAKEOVER EFFECTS OF TWO CLASSES OF STOCK

The Company's business is managed by a small number of key management and
operating personnel, the loss of certain of whom could have a material adverse
effect on the Company's business, results of operations and financial condition.
The Company believes that its future success will depend in large part on its
ability to attract and retain highly skilled and qualified personnel and to
expand, train and manage its employee base. None of the Company's key
executives, other than Stephen A. Garofalo, Chief Executive Officer, Secretary
and Chairman of the Board, and Howard Finkelstein, President and Chief Operating
Officer, is presently a party to an employment or non-competition agreement with
the Company. See "Management--Employment Agreements."

The holders of Class A Common Stock are entitled to one vote per share.
Holders of Class B Common Stock are entitled to ten votes per share and vote as
a separate class to elect at least 75% of the members of the Board of Directors.
Each share of Class B Common Stock is convertible at any time into one share of
Class A Common Stock, and with limited exceptions converts automatically upon
any transfer thereof. Stephen A. Garofalo currently controls approximately 55.3%
of the outstanding shares of Class A Common Stock. Metromedia and certain of its
affiliates currently own 100% of the Class B Common Stock, and represent
approximately 76.4% of the Company's total voting power (on a fully diluted
basis, without giving effect to the Offerings). Accordingly, Metromedia will be
able to control the Board of Directors and all shareholders decisions and, in
general, to determine (without the consent of the Company's other stockholders)
the outcome of any corporate transaction or other matter submitted to the
stockholders for approval, including mergers, consolidations and the sale of all
or substantially all of the Company's assets. In addition, Metromedia has the
power to prevent or cause a change in control of the Company. See "Description
of Capital Stock," "Principal Shareholders" and "Certain Relationships and
Related Transactions."

ABSENCE OF PRIOR PUBLIC MARKET FOR COMMON STOCK; POSSIBLE VOLATILITY OF STOCK
PRICE

Prior to the Offerings, there has been no public market for the Class A
Common Stock. The initial public offering price of the Class A Common Stock will
be determined by negotiations among the Company and the Representatives of the
Underwriters (each as defined herein), and may bear no relationship to the price
at which the Class A Common Stock will trade after completion of the Offerings.
The Class A Common Stock has been approved for listing, subject to notice of
issuance, on the Nasdaq National Market; however, there can be no assurance that
an active trading market will develop or be maintained for the Class A Common
Stock following the Offerings or that the Class A Common Stock will trade in the
public market at or above the initial public offering price. For factors
considered in determining the initial public offering price, see "Underwriting."
After completion of the Offerings, the market price of the Class A Common Stock
will be subject to fluctuations in response to various factors and events,
including the liquidity of the market for the Class A Common Stock, variations
in the Company's

15
<PAGE>
quarterly operating results, regulatory or other changes, both domestic and
international, affecting the communications industry generally or the Company
specifically, announcements of business developments by the Company or its
competitors, changes in operating results and changes in general market
conditions. See "--Limited History of Operations; Negative Losses and Negative
Cash Flow from Operations; Expected Future Net Losses and Negative Cash Flow
from Operations", "--Extensive Regulation", "--Risk of Cancellation or
Non-Renewal of Franchises, Licenses or Permits" and "-- Competitive Industry."

SHARES ELIGIBLE FOR FUTURE SALE; POTENTIAL ADVERSE EFFECT ON STOCK PRICE;
REGISTRATION RIGHTS

Sales of a substantial number of shares of Class A Common Stock in the
public market, or the perception that such sales may occur could adversely
effect prevailing market prices for the Class A Common Stock and the ability of
the Company to raise capital in the future. Upon completion of the Offerings,
the Company will have outstanding shares of Class A Common Stock. Of such
shares, the shares of Class A Common Stock being sold in the Offerings
(together with any shares sold upon exercise of the Underwriters' over-allotment
option) will be immediately eligible for sale in the public market without
restriction, except for shares purchased by or issued to any affiliate (an
"Affiliate") of the Company (within the meaning of the Securities Act of 1933,
as amended (the "Securities Act")). For so long as any stockholder remains an
Affiliate of the Company, any shares of Class A Common Stock held by such person
will only be available for public sale if such shares are registered under the
Securities Act or sold in accordance with an applicable exemption from
registration, such as Rule 144 ("Rule 144") of the Securities Act, and any sales
by an Affiliate under Rule 144 would be subject to the volume and other
limitations under such rule. shares of Class A Common Stock (including
shares of Class B Common Stock which are convertible into Shares of Class A
Common Stock) which are "restricted securities", as that term is defined in Rule
144, owned by persons who are neither Affiliates of the Company nor subject to
lock-up agreements with the Underwriters are currently eligible for sale under
Rule 144. Upon the expiration or waiver of certain lock-up agreements with the
Underwriters, approximately additional shares of Class A Common Stock will
be eligible for sale in the public market pursuant to Rule 144. Pursuant to
lock-up agreements with the Underwriters, the Company and executive officers and
directors of the Company have agreed not to offer, sell, contract to sell or
otherwise dispose of, directly or indirectly, any shares of Class A Common Stock
or any securities of the Company that are substantially similar to the Class A
Common Stock, including but not limited to any securities that are convertible
into or exchangeable for, or that represent the right to receive, Class A Common
Stock or any such substantially similar securities (other than pursuant to
employee or director stock or stock option plans existing on the date of this
Prospectus) for a period of 180 days after the date of this Prospectus without
the prior written consent of Salomon Brothers Inc, except for the shares of
Class A Common Stock offered in connection with the Offerings. See "Certain
Relationships and Related Transactions," "Description of Capital Stock" and
"Shares Eligible for Future Sale."

ABSENCE OF DIVIDENDS

The Company anticipates that all of its earnings in the foreseeable future
will be retained to finance the continued growth and expansion of its business
and has no current intention to pay cash dividends on its Class A Common Stock.
See "Dividend Policy."

IMMEDIATE AND SUBSTANTIAL DILUTION

Purchasers of Class A Common Stock in the Offerings will experience
immediate and substantial dilution of $ per share in the net tangible book
value per share of outstanding Class A Common Stock. See "Dilution."

16
<PAGE>
USE OF PROCEEDS

The net proceeds from the Offerings are estimated to be approximately
$ million (approximately $ million if the Underwriters'
over-allotment option is exercised in full) after deducting estimated expenses
of the Offerings payable by the Company. Such net proceeds will be used
primarily for capital expenditures associated with the build-out of the MFN
Network, the development and introduction of new services and for general
corporate and working capital purposes. See "Business."

There can be no assurance that the Company's actual application of the
proceeds will not vary substantially from the Company's current plans. Moreover,
the Company will need additional capital to (i) finance the completion of its
planned network, (ii) fund working capital needs and future debt service
obligations, (iii) take advantage of unanticipated opportunities, including more
rapid international expansion, acquisitions of businesses, investments in, or
strategic alliances with, companies that are complementary to the Company's
current operations, (iv) develop or expand into new services or (v) otherwise
respond to unanticipated competitive pressures. See "Risk Factors--Competitive
Industry," "--Risks Associated with Acquisitions, Investments and Strategic
Alliances" and "Business--Business Strategy."

Pending application of the net proceeds of the Offerings, the Company
expects that it will place such net proceeds in interest-bearing bank accounts
or invest such proceeds in United States government securities or other
short-term, interest bearing, investment grade securities. The Company is not
currently, and does not expect as a result of the Offerings to become, subject
to the registration requirements of the Investment Company Act of 1940.

DIVIDEND POLICY

The Company has never declared or paid any cash dividends on its Class A
Common Stock and does not expect to do so in the foreseeable future. The Company
anticipates that all future earnings, if any, generated from operations will be
retained to finance the expansion and continued development of its business. Any
future determination with respect to the payment of dividends will be within the
sole discretion of the Company's Board and will depend upon, among other things,
the Company's earnings, capital requirements, the terms of then existing
indebtedness, applicable requirements of the Delaware General Corporation Law
(the "DGCL"), general economic conditions and such other factors considered
relevant by the Company's Board. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations."

<PAGE>
DILUTION

As of June 30, 1997, the net tangible book value of the Company was
approximately $ , or $ per share of outstanding Common Stock (taking
into account the Reverse Stock Split and the Reclassifications). Net tangible
book value per share of Common Stock represents the total amount of tangible
assets of the Company, less the total amount of liabilities of the Company,
divided by the number of shares of Common Stock outstanding. After giving effect
to Reverse Stock Split, Reclassifications and the sale by the Company of the
shares of Class A Common Stock offered hereby at an assumed initial
offering price of $ per share (the midpoint of the range of prices set
forth on the cover page of this Prospectus) and assuming no exercise of the
Underwriters' over-allotment option and the application of the net proceeds
therefrom (after deducting estimated offering expenses payable by the Company

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS

THE FOLLOWING DISCUSSION SHOULD BE READ IN CONJUNCTION WITH "SELECTED
CONSOLIDATED FINANCIAL AND OTHER DATA" AND THE CONSOLIDATED FINANCIAL STATEMENTS
OF THE COMPANY, INCLUDING THE NOTES RELATED THERETO, AND THE OTHER FINANCIAL
DATA APPEARING ELSEWHERE IN THIS PROSPECTUS.

STATEMENT ON FORWARD-LOOKING INFORMATION

CERTAIN INFORMATION INCLUDED HEREIN CONTAINS STATEMENTS THAT CONSTITUTE
"FORWARD-LOOKING STATEMENTS" WITHIN THE MEANING OF THE PRIVATE SECURITIES
LITIGATION REFORM ACT OF 1995. SUCH FORWARD LOOKING STATEMENTS INVOLVE KNOWN AND
UNKNOWN RISKS, UNCERTAINTIES AND OTHER FACTORS THAT MAY CAUSE THE ACTUAL
RESULTS, PERFORMANCE OR ACHIEVEMENTS OF THE COMPANY TO BE MATERIALLY DIFFERENT
FROM ANY FUTURE RESULTS, PERFORMANCE OR ACHIEVEMENTS EXPRESSED OR IMPLIED BY
SUCH FORWARD-LOOKING STATEMENTS. SUCH FACTORS INCLUDE, AMONG OTHERS, THE
FOLLOWING: GENERAL ECONOMIC AND BUSINESS CONDITIONS; INDUSTRY CAPACITY;
UNCERTAINTY REGARDING AND CHANGES IN CUSTOMER PREFERENCES; DEMOGRAPHIC CHANGES;
COMPETITION; CHANGES IN METHODS OF MARKETING AND TECHNOLOGY; CHANGES IN
POLITICAL, SOCIAL AND ECONOMIC CONDITIONS AND REGULATORY FACTORS AND VARIOUS
OTHER FACTORS BEYOND THE COMPANY'S CONTROL.

GENERAL

The Company is a facilities-based provider of technologically advanced,
high-bandwidth fiber optic communications infrastructure to carrier and
corporate/government customers, primarily in the form of leased fiber optic
cables and circuits. The Company currently derives all of its revenues in
connection with leasing dark fiber on the NY Network. Fees paid to the Company
by communications carriers and corporate and government customers are on an
unmetered basis. The costs associated with the initial development and
construction of the NY Network include engineering, installation, conduit, fiber
cable and easement costs. A substantial portion of these costs are incurred
before the realization of revenues and result in negative cash flow. The
Company's other operating expenses consist of selling, general and
administrative expenses ("SG&A"), as well as depreciation and amortization. The
franchise fees were included in Cost of Sales for the year ended December 31,
1996, while for the years ended December 31, 1994 and 1995 such fees were
classified as SG&A. The franchise fee payable to the City of New York is
currently 6% of Gross Revenues, and for 1998 and thereafter for the remainder of
the term of the franchise, the fee will be 5% of Gross Revenues. See
"Business--Franchise, License and Related Agreements--New York City Franchise
Agreement". "Gross Revenues" is defined in the NYC Franchise Agreement as all
revenues received directly or indirectly by the Company or any affiliate of the
Company from or in connection with telecommunications services which originate
in, terminate in, or transit New York City. Revenues that are generated from
transmissions which transit New York City, but also include transmission through
other areas, are to be pro-rated. The minimum franchise fee payable to the City
of New York is $200,000 per annum.

The Company's proposed business strategy includes the expansion of the NY
Network, construction of intra-city networks in Washington, D.C., Chicago and
Philadelphia and construction of an inter-city network between New York City and
Washington, D.C. Revenues will continue to be derived from fixed unmetered
charges for the provision of fiber optic capacity. If the Company does not
complete certain construction by a specified time, some of these contracts may
be terminated. There can be no assurance that the Company will complete the
expansion of the NY Network in a timely manner or that certain contracts will
not be terminated. The Company anticipates that as its expansion progresses
revenues derived from carrier customers as opposed to corporate and government
customers will constitute an increasing percentage of the Company's revenue base
due to the larger volume of capacity typically required by carriers. The
expansion of the NY Network and the construction of additional networks will
require additional expenditures. Expenses for the planned expansion consist of
engineering, installation, conduit, fiber cable and easement costs. These
expenses will result in negative

22
<PAGE>
cash flow until an adequate customer base is established. Once its networks are
completed and such a customer base is established, the Company expects that
incremental revenues can be added with relatively low additional expense, due to
the predominantly fixed nature of the Company's costs.

To date, the Company has signed certain of its customers to long term leases
which require an upfront payment rather than recurring monthly payments over the
term of a lease. The Company intends to continue this practice in the future to
the extent that it is economically practical. If the Company continues to sign
up new leases on these terms, the incoming cash flows from such upfront payments
in the early years, when the use of capital is greatest, may be greater than the
revenue recognized on an accrual basis. The Company also intends to attempt to
have customers fund a portion of the Company's construction expenses. To the
extent this occurs in future leases, incoming cash flows in the early years may
be greater than the revenue recognized on an accrual basis and the opposite will
be true in the later years of such leases.

RESULTS OF OPERATIONS

SIX MONTHS ENDED JUNE 30, 1997 COMPARED TO SIX MONTHS ENDED JUNE 30, 1996

REVENUES. Total revenues increased to $541,886 for the six months ended
June 30, 1997 from $82,035 for the six months ended June 30, 1996, representing
an increase of $459,851. Approximately one half of this increase was derived
from lease revenue recognition with the remainder resulting from one-time
non-lease revenues. The increase in lease revenues resulted from an increase in
the customer base.

COST OF SALES. Cost of sales increased to $1,081,677 for the six months
ended June 30, 1997 from $265,029 for the six months ended June 30, 1996,
representing an increase of $816,648. The increase was primarily due to costs
associated with one time non-lease revenue recognition during the period.

SELLING, GENERAL AND ADMINISTRATIVE. SG&A increased to $2,186,291 for the
six months ended June 30, 1997 from $1,276,853 for the six months ended June 30,
1996, an increase of $909,438. This increase is primarily a result of increased
headcount due to the staffing of the organization to accomodate the anticipated
growth of the Company. Legal expenses also increased as a result of the
increased business activity within the organization.

NON-RECURRING CONSULTING AND EMPLOYMENT INCENTIVES. Non-recurring
consulting and employment incentives increased to $16,419,900 for the six months
ended June 30, 1997 from $3,651,442 for the six months ended June 30, 1996,
reflecting an increase of $12,768,458. This increase is due to the increase in
issuance of equity instruments to key employees of the Company during the
period.

DEPRECIATION AND AMORTIZATION. Depreciation and amortization increased to
$372,935 for the six months ended June 30, 1997 from $292,319 for the six months
ended June 30, 1996, representing an increase of $80,616. The increase in
depreciation and amortization relates to the increased size of the Company's
fiber optic network versus the prior year.

INTEREST INCOME. Interest income of $204,175 was recorded for the six
months ended June 30, 1997. Interest income in 1997 was derived from the
short-term investment of the Company's excess cash. In 1996, there was no excess
cash available for investing and no interest income.

INTEREST EXPENSE (INCLUDING FINANCING COSTS). Interest expense (including
financing costs) decreased to $679,427 for the six months ended June 30, 1997
from $1,807,956 for the six months ended June 30, 1996, representing a decrease
of $1,128,529. The decrease was primarily due to the repayment of debt from the
proceeds of the Metromedia Investment in April 1997. The Company

23
<PAGE>
incurred higher financing costs for the six months ended June 30, 1996 due to
efforts to fund the expanded operations of the Company.

NET LOSS. Net loss increased to $19,994,169 for the six months ended June
30, 1997 from $7,211,564 for the six months ended June 30, 1996, representing an
increase of $12,782,605. The increase in the loss is the result of the factors
discussed above, primarily the increase in non-recurring consulting and
employment incentives.

YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995

The Company was in its early development stage and did not generate its
first revenues until the last three months of 1995 when customers began using
the Company's facilities.

REVENUES. Total revenues increased to $236,082 for the year ended December
31, 1996 from $56,149 for the year ended December 31, 1995, representing an
increase of $179,933. The increase in revenue is due primarily to an increase in
the number of customers.

COST OF SALES. Cost of sales was $698,793 for the year ended December 31,
1996. There were no cost of sales recorded for the year ended December 31, 1995.
The increase was primarily attributable to the inclusion of franchise and
easement fees in cost of sales.

SELLING, GENERAL AND ADMINISTRATIVE. SG&A decreased to $2,070,345 for the
year ended December 31, 1996 from $3,886,568 for the year ended December 31,
1995, representing a decrease of $1,816,223.

NON-RECURRING CONSULTING AND EMPLOYMENT INCENTIVES. Non-recurring
consulting and employment incentives were $3,652,101 for the year ended December
31, 1996 versus none in 1995, reflecting the Company's issuance of equity
instruments for consulting services.

DEPRECIATION AND AMORTIZATION. Depreciation and amortization increased to
$612,530 for the year ended December 31, 1996 from $161,576 for the year ended
December 31, 1995, representing an increase of $450,954. Certain components of
depreciation and amortization are recognized by the Company upon commencement of
service to customers, which did not occur until late 1995. As a result,
depreciation and amortization in 1996 was larger than it was in 1995 due to the
inclusion of a full year of depreciation and amortization.

INTEREST EXPENSE (INCLUDING FINANCING COSTS). Interest Expense (including
financing costs) increased to $3,561,010 for the year ended December 31, 1996
from $327,106 for the year ended December 31, 1995, representing an increase of
$3,233,904. This increase was a result of additional debt incurred in 1996 to
finance construction of the NY Network and to fund the operations of the
Company.

NET LOSS. Net Loss increased to $10,358,697 for the year ended December 31,
1996 from $4,319,101 for the year ended December 31, 1995, representing an
increase of $6,039,596. The increase in net loss is attributable to the factors
discussed above.

YEAR ENDED DECEMBER 31, 1995 COMPARED TO YEAR ENDED DECEMBER 31, 1994

REVENUES. Total revenues were $56,149 for the year ended December 31, 1995.
The Company did not recognize any revenues for the year ended December 31, 1994.

COST OF SALES. There were no costs of sales incurred for the years ended
December 31, 1995 and December 31, 1994. Any franchise fees and easement costs
were recognized in SG&A during these periods.

24
<PAGE>
SELLING, GENERAL AND ADMINISTRATIVE. SG&A increased to $3,886,568 for the
year ended December 31, 1995 from $874,000 for the year ended December 31, 1994,
representing an increase of $3,012,568. This increase is primarily the result of
increased sales, marketing and administrative expenses associated with the
Company's start up phase.

DEPRECIATION AND AMORTIZATION. Depreciation and amortization was $161,576
for the year ended December 31, 1995 and began to be recognized upon
commencement of service to customers in late 1995.

INTEREST EXPENSE. Interest Expense was $327,106 for the year ended December
31, 1995 primarily due to debt incurred to finance the construction of the NY
Network.

NET LOSS. Net Loss increased to $4,319,101 for the year ended December 31,
1995 from $874,000 for the year ended December 31, 1994, representing an
increase of $3,445,101. The increase in net loss is attributable to the factors
discussed above.

LIQUIDITY AND CAPITAL RESOURCES

Since its organization in 1993, the Company has funded capital expenditures,
debt service and cash used in operations through a combination of private
placements of debt and equity securities and stockholder advances. The Company's
operations generated insufficient cash flows in 1993 through 1996 to enable it
to meet its capital expenditures, debt service and other cash needs. At December
31, 1996 and 1995, the Company had working capital deficits of approximately
$12.9 million and $11.5 million respectively.

On April 30, 1997, the Company issued and sold to Metromedia and certain of
its affiliates equity interests, substantially all of which will be reclassified
as Class B Common Stock, for a gross sale price of $32.5 million, the proceeds
of which were used to repay indebtedness and repurchase certain equity
securities. See "Capitalization" and "Certain Relationships and Related
Transactions--Recent Transactions."

The Company anticipates that it will continue to incur net operating losses
as it expands the NY Network, constructs additional networks and markets its
services to an expanding customer base. Cash provided by operations will not be
sufficient to fund the expansion and development of networks as currently
planned and as a result the Company intends to use cash on hand and the net
proceeds of the Offerings to fund this expansion and development.

The build-out of the NY Network, the construction of additional networks and
the marketing of the Company's services will require substantial capital. Such
capital expenditures for years ended, 1994, 1995 and 1996 were $548,000,
$3,709,928 and $974,107 respectively. The Company currently estimates that, in
building out the MFN Network, its capital expenditure requirements for the
period from June 30, 1997 through the end of 1998 are expected to be
approximately $140.0 million.

Management believes that the remaining net proceeds from the Metromedia
Investment together with the net proceeds from the Offerings contemplated hereby
will be sufficient to fund the Company's capital requirements over the next 15
months. In addition, in order to fund its capital requirements, the Company may
consider from time-to-time the private or public sale of additional equity or
debt securities of the Company depending upon market conditions. There can be no
assurance that the Company will be able to successfully consummate any such
financing on acceptable terms.

BUSINESS

THE COMPANY

GENERAL

The Company is a facilities-based provider of technologically advanced,
high-bandwidth, fiber optic communications infrastructure to carrier and
corporate/government customers. The Company is expanding its existing network to
encompass approximately 229,000 fiber miles, or 643 route miles, concentrated in
the northeastern United States, a market which the Company believes is
characterized by significant demand for and limited supply of fiber optic
capacity. The fiber infrastructure leased by MFN to its customers provides
high-bandwidth capacity for customers that seek to establish secure
communications networks for the transmission of large amounts of voice, data and
video. For example, a pair of MFN fiber optic strands can transmit up to 8.6
gigabits of data per second or the equivalent of approximately 129,000
simultaneous voice conversations.

The Company tailors the amounts of capacity leased to the needs of its
customers. Certain customers that lease fiber optic capacity from the Company
connect their own transmission equipment to the leased fiber, thereby obtaining
a fixed-cost, secure telecommunications alternative to the metered
communications services offered by traditional providers. Other customers that
require lesser amounts of transmission capacity will have the option to lease
such broadband capacity on the Company's network, whereby the Company
effectively divides a single strand of fiber into multiple smaller
communications channels. The Company believes that it will have installation,
operating, and maintenance cost advantages per fiber mile relative to its
competitors because MFN installs its network with as many as 432 fibers per
route mile as compared to a generally lower number of fibers in existing
competitive networks.

The Company was formed in 1993 and currently operates a 54 route mile fiber
optic communications network in the New York/New Jersey metropolitan area (the
"NY Network"), consisting of 7,188 fiber miles, approximately two-thirds of
which are currently available for lease. Within the next two years the Company
plans to complete an expansion of the NY Network to increase its coverage within
the New York/New Jersey metropolitan area. In addition, the Company intends to
construct intra-city fiber optic networks in Washington, D.C., Chicago and
Philadelphia and an inter-city fiber optic route between New York City and
Washington, D.C. The Company currently intends to expand its network in order to
connect the NY Network with other major domestic metropolitan areas, in part
through the exchange of fiber capacity with other carriers, and to extend its
network to link the NY Network to London, England, thereby providing a valuable
connection between two of the world's most important financial centers. See
"Build-out of Networks," and "Risk Factors -- Risks Associated with Growth
Strategy." The Company's NY Network supports a self-healing SONET architecture
that minimizes the risk of downtime in the event of a fiber cut and provides
MFN's customers with high security and reliability. It is expected that the
Company's other Intra-City Networks will also support a self-healing SONET
architecture. Most of the Company's fiber is installed inside high density
polyethylene conduit to protect the cable and, where practicable, MFN installs
additional unused conduits to accommodate future network expansion.

26
<PAGE>
The Company believes that it will be well-positioned to penetrate the corporate
and government markets since it plans to continue to install most of its fiber
in Tier I markets. See "Business -- Customers."

On April 30, 1997, Metromedia and certain of its affiliates made a
substantial equity investment in the Company. Metromedia and its partners own
all of the outstanding shares of Class B Common Stock which is entitled to 10
votes per share and to vote separately to elect at least 75% of the members of
the Board. As a result, Metromedia and its partners own and control
approximately 25% of the common equity of the Company (on a fully diluted basis)
and approximately 76.4% of the outstanding voting power (on a fully diluted
basis). Metromedia and its predecessor have successfully invested in and
operated numerous businesses in the communications industry, including cellular,
paging, long distance and media companies. In connection with the Metromedia
Investment, John W. Kluge and Stuart Subotnick who bring considerable management
and corporate governance experience to the Company, joined MFN's Board. See
"Certain Relationships and Related Transactions."

INCREASING DEMAND FOR HIGH-BANDWIDTH CAPACITY

- RAPID GROWTH OF COMMUNICATIONS TRAFFIC. Industry research indicates that
data traffic is growing by 35% annually with demand for data services
outpacing that for voice by 20 times. The Internet, for example, has been
growing at a compound annual rate of more than 100% per year for the past
decade and it is anticipated to reach 20 million host computers connected
to the Internet by the end of 1997. Business connectivity, in particular,
is expected to grow at a rate of 65% annually to reach almost $6.4 billion
by the end of 2000. With an advanced fiber optic network, the Company
believes that it is well-positioned to take advantage of this rapid
growth.

- CAPACITY REQUIRED BY NEW ENTRANTS. Competition and deregulation are
bringing new entrants into the telecommunications market. The 1996 Act
allows the RBOCs to enter the long distance business and enables other
entities, including entities affiliated with power utilities and ventures
between ILECs and cable television companies, to provide an expanded range
of telecommunications services. The Company believes that the opening of
various telecommunications markets will lead to an increase in demand for
fiber optic cable and circuits as more communications carriers elect to
compete. As a carriers' carrier, MFN believes that carrier customers
typically would lease fiber optic capacity with which they would develop
their own communications networks as a low-cost alternative to building
their own infrastructure or purchasing metered services from ILECs or
CLECs. The Company believes that its fiber optic communications network
will provide a cost effective alternative for market entrants in a number
of communications industry segments, including ILECs, CLECs, IXCs,
wireless companies and ISPs.

- EXPECTED UPGRADES TO OLDER COMMUNICATIONS NETWORKS. Approximately 92% of
the RBOCs' networks currently are comprised of copper cable. The RBOCs
will likely need to replace or upgrade their networks to remain
competitive and satisfy their customers' increasing demand for
high-bandwidth capacity in the coming years. The Company believes that the
RBOCs will seek cost-effective and expedient solutions when faced with the
decision to buy or build fiber optic capacity which could result in
increased demand for the Company's infrastructure.

- ACCOMMODATION OF OTHER NEW APPLICATIONS. The Company believes that
additional network transmission capacity and faster response times will be
required to accommodate the needs of multimedia (voice, data and video)
and other potential high-bandwidth applications, including the deployment
of corporate intranets and the use of telecommunications infrastructure
for providing cable television and other entertainment services. Because
applications such as intranet and

27
<PAGE>
Frame Relay can use as much as OC-48 to OC-192 each, the Company believes
that there will be significant demand for its high-bandwidth
communications infrastructure.

According to an industry report, the total 1995 market for communications
services in the United States was approximately $282 billion and is expected to
grow to approximately $457 billion by the year 2000. In addition, the Company
believes there will be increased demand for its infrastructure due to its
ability to offer fixed-cost pricing which is generally more economical for high
volume users than traditional usage-based pricing.

BUSINESS STRATEGY

ESTABLISH THE COMPANY AS THE PREFERRED CARRIERS' CARRIER OF BROADBAND
COMMUNICATIONS INFRASTRUCTURE.

MFN leases broadband communications infrastructure on a fixed-cost basis to
various communications carriers, thus enabling them to compete in markets which
were previously difficult to penetrate due to limited and/or costly access to
high-bandwidth communications infrastructure. Specifically, the Company plans to
lease local transmission capacity within its target Tier I markets thereby
enabling its carrier customers to bypass the ILECs and CLECs. The Company
believes that it is currently the only provider providing local transmission
infrastructure on a fixed-cost basis. Additionally, the Company plans to lease
capacity on its high-bandwidth, long-haul Inter-City Network to provide seamless
connectivity between its various Intra-City Networks. The Company's fixed-cost,
long-term contracts allow its carrier customers to access certain Tier I markets
without incurring the high capital expenditures and long lead times usually
associated with building their own networks. Carriers may be more likely to
lease capacity from MFN rather than from a competitor since MFN currently has no
plans to offer communications infrastructure services on a metered basis,
choosing instead to position itself as a non-competing provider of
infrastructure alternatives for IXCs, ILECs, CLECs, etc. See "Customers."

POSITION THE COMPANY AS THE PREFERRED PROVIDER OF BROADBAND COMMUNICATIONS
INFRASTRUCTURE TO CORPORATE AND GOVERNMENT CUSTOMERS.

STRENGTHEN MFN'S COMPETITIVE POSITION BY EXPANDING THE MFN NETWORK.

28
<PAGE>
Philadelphia and (iii) constructing a fiber optic backbone between New York City
and Washington, D.C. to link certain of its Intra-city Networks. Once completed,
MFN's domestic fiber optic network infrastructure, as currently planned, will
consist of approximately 229,000 fiber miles covering 643 route miles.

UTILIZE STRATEGIC RELATIONSHIPS TO EXPAND THE REACH OF THE MFN NETWORK.

Another part of MFN's strategy is to enter into agreements with other
communications companies to expand the reach of the MFN Network. MFN has signed
a letter of cooperation with a leading global voice and data communications
provider in the United Kingdom. A definitive agreement, if entered into, would
expand the reach of MFN's network to the United Kingdom and provide seamless
connectivity between two leading financial centers, New York City and London.
The Company believes that its presence in Tier I markets will continue to
provide similar partnering opportunities. The Company will continue to evaluate
opportunities, including potential fiber swaps, along specific additional routes
in order to speed the build-out of the MFN Network and reduce costs.

CREATE A LOW COST POSITION.

The Company believes it will be able to establish a low cost position
relative to its competitors primarily for the following reasons: (i) the Company
currently installs trunks of up to 432 fibers per route mile, which the Company
believes is significantly more fiber than many of its competitors install,
thereby reducing the per fiber mile cost to construct and operate the MFN
Network, (ii) the Company owns a newly-constructed network with advanced fiber
optic technology which offers operating and maintenance cost advantages, (iii)
the Company believes that certain of its rights-of-way and franchises are
valuable assets that will be costly and difficult for others to procure in the
future and (iv) MFN, where practicable, installs spare conduit which will allow
for expanded fiber optic capacity at a cost significantly below the cost of new
construction. The Company's low cost position will allow it to remain price
competitive with other providers of fiber optic infrastructure and to lease its
fiber infrastructure at a price which customers will find more attractive than
the cost of constructing their own networks.

INSTALL A TECHNOLOGICALLY ADVANCED NETWORK.

The Company believes that the advanced technical characteristics of its
network will allow it to provide high levels of reliability, security and
capacity that its target customers typically demand. The NY Network is, and
future extensions of the Intra-City Networks will be, capable of supporting a
SONET ring architecture, which prevents interruption in service to its clients
by instantaneously rerouting traffic in the event of a fiber cut. The Company
will also continuously monitor and maintain high quality control of its network
on a 24-hour basis through its network operations center. The Company's network
is capable of using the highest commercially available capacity transmission
(OC-192) and thereby can handle advanced, capacity-intensive data applications
such as Frame Relay, ATM, multimedia and Internet-related applications.

BUILD ON MANAGEMENT EXPERIENCE.

The Company's management team and Board include individuals with
communications industry expertise and extensive experience in network design,
construction, operations and sales. MFN's Chief Executive Officer, Stephen A.
Garofalo, has approximately 25 years of experience in the cable installation
business, having managed the installation of over one half billion dollars in
electrical and communications cable in New York City. In April 1997, the Company
hired Howard Finkelstein as President and Chief Operating Officer. From 1984 to
1993, Mr. Finkelstein served as President of Metromedia Communications
Corporation, Metromedia's long distance telephone enterprise, until its merger
with WorldCom, Inc. in 1993. In his most recent position, Mr. Finkelstein was
the Chief Operating Officer and an Executive Vice President of Metromedia
International Telecommunications, Inc. He has also served in various capacities
at Metromedia and its affiliated companies over a period of 16 years. The
Company also

29
<PAGE>
expects to benefit from the communications industry expertise and corporate
governance experience of John W. Kluge and Stuart Subotnick, members of its
Board. See "Certain Relationships and Related Transactions."

BUILD-OUT OF NETWORKS

Since its founding in 1993 the Company has concentrated solely on developing
and constructing its NY Network. The Company has developed a plan for the
expansion of the NY Network and the construction of new fiber optic Intra-City
Networks and an Inter-City Network and is pursuing the acquisition of necessary
licenses, franchises and rights-of-way. See "Risk Factors--Risks Associated with
Growth Strategy; Management of Expansion." In constructing its fiber optic
networks, the Company seeks to create strategic alliances with the engineering
and construction management firms that have been engaged to develop routes,
easements and manage deployment plans. All firms with whom the Company is allied
in this regard have deployed local loop network infrastructure for RBOCs as well
as for CLECs. Though much of the actual construction will be outsourced to
various construction firms, the Company maintains strict oversight of the design
and implementation of its fiber optic communications networks.

NY NETWORK. The NY Network currently consists of a 54 route mile fiber
optic communications network in the New York/New Jersey metropolitan area
consisting of 7,188 fiber miles, approximately two-thirds of which are currently
available for lease. As currently planned, the expansion of the NY Network will
add 125 route miles with each additional route-mile consisting of up to 432
fibers. Upon its completion, the entire NY Network will utilize a SONET capable
fiber ring focused in Manhattan and extending east to Brookhaven, Long Island,
north to White Plains, Westchester County, west to Jersey City, New Jersey, and
south to Brooklyn, New York. The expanded NY Network is expected to pass more
than 800 buildings in New York City and to pass through 31 RBOC central offices,
which are believed to connect to over 15 million people and over 400,000
businesses.

INTRA-CITY NETWORKS. Subject to the receipt of the necessary franchises,
licenses and rights-of-way, the Company plans to construct additional fiber
optic communications networks in Washington, D.C., Chicago, and Philadelphia. No
assurance can be given that the necessary franchises, licenses and rights-of-way
will be obtained or consummated or will provide all of the rights needed to
implement the Company's strategy on acceptable terms. The following table sets
forth the Company's estimates of route miles and fiber miles for each of the
proposed Intra-City Networks. The Company anticipates it will use existing cash
balances and the proceeds from the Offerings, amounts received from long-term
lease arrangements from customers and additional debt or equity financings to
finance the construction of these proposed networks.

INTER-CITY NETWORK. Subject to the receipt of the necessary franchises,
licenses and rights-of-way, the Company plans to construct and operate its
Inter-City Network between New York City and Washington, D.C., covering
approximately 114,000 fiber miles (or 264 route miles). The Company has
completed or is in the process of negotiating for the acquisition of
rights-of-way with respect to existing conduit alternatives, as well as
construction easements with major rail and civil authorities along the route. No
assurance can be given that the necessary franchises, licenses and rights-of-way
needed to implement the Company's strategy on acceptable terms will be obtained.

30
<PAGE>
RIGHTS-OF-WAY. When the Company decides to build a fiber optic
communications network, its corporate development staff seeks to obtain the
necessary city authorizations. In some cities, a construction permit is all that
is required. In other cities, a license agreement or franchise is also required.
Such licenses and franchises are generally for a term of limited duration. Where
possible, rights-of-way are leased under multi-year agreements with renewal
options and are generally non-exclusive. The Company strives to obtain
rights-of-way that afford it the opportunity to expand its communications
networks as business develops.

The Company plans to lease underground conduit and pole space and other
rights-of-way from entities such as ILECs, utilities, railroads, IXCs, state
highway authorities, local governments and transit authorities.

The following is a summary of the status of MFN's efforts to secure
rights-of-way:

- NEW YORK CITY: The NYC Franchise Agreement grants MFN the right, until
December 2008, to install, operate, repair, maintain, remove and replace
cable, wire, fiber or other transmission media that may be used in lieu of
cable, wire or fiber on, over and under the inalienable property of New
York City in order to provide telecommunications services which originate
and/or terminate in or transit New York City. The Conduit Occupancy
Agreement (as defined herein) between the Company and NYNEX, together with
easements granted to the Company by ECS, authorize the installation of the
Company's fiber optic communications network in NYNEX's conduit system and
the conduit system associated with the ECS, respectively. See "Franchise,
License and Related Agreements--New York City Franchise Agreement,"
"--Conduit Occupancy Agreement" and "Risk Factors--Risk of Cancellation or
Non-Renewal of Franchises, Licenses or Permits."

- CHICAGO: MFN is negotiating easements and rights-of-way for Chicago with
two entities. MFN is also investigating procuring the required franchises,
licenses, permits and other agreements needed to complete its Chicago
network. No assurance can be given that these agreements will be
consummated or will provide all of the rights-of-way needed by MFN in
Chicago.

- WASHINGTON, D.C.: The Company has obtained rights-of-way for a portion of
the Washington, D.C. Intra-City Network and is investigating obtaining the
necessary licenses and permits for this network.

- PHILADELPHIA: MFN has negotiated with the City of Philadelphia for
permission, subject to certain conditions, to construct, maintain and
operate, replace and remove a telecommunications system in, under and
across the public rights-of-way and city streets and/or to place such
telecommunications system within the existing facilities owned by Bell
Atlantic Corporation, PECO Energy Company, Southeastern Pennsylvania
Transportation Authority, Consolidated Rail Corporation or any other
entity holding a grant pursuant to City ordinances. An appropriate
ordinance was passed by the Philadelphia city council in June 1997 and the
Company expects to enter into formal licenses and other agreements
shortly.

In developing the Inter-City Network, MFN is negotiating with certain rail
transportation providers, public utilities, RBOCs and others to accomplish the
Company's goal of providing its customers with a flexible network architecture.
No assurance can be given that these agreements will be consummated or that the
rights-of-way needed by MFN will be obtained throughout the intended route of
the Inter-City Network.

ADVANCED TECHNOLOGY.

The MFN Network consists of fiber optic communication paths which allow for
high speed, high quality transmission of voice, data and video communications.
Fiber optic systems use laser-generated light to transmit voice, data and video
in digital formats through ultra-thin strands of glass. Fiber optic

31
<PAGE>
systems are generally characterized by large circuit capacity, good sound
quality, resistance to external signal interference and direct interface to
digital switching equipment or digital microwave systems. The Company plans to
install backbone fiber optic cables containing up to 432 fiber optic strands,
which have significantly greater bandwidth than traditional analog copper
cables. Using current electronic transmitting devices, a single pair of glass
fibers used by the Company's network can transmit up to 8.6 gigabits of data per
second or the equivalent of approximately 129,000 simultaneous voice
conversations, which is substantially more than traditional analog copper cable
installed in many current communications networks. The Company believes that
continuing developments in compression technology and multiplexing equipment
will increase the capacity of each fiber optic strand, thereby providing more
bandwidth carrying capacity at relatively low incremental costs. See "Risk
Factors--Rapid Technological Change."

The Company offers end-to-end fiber optic capacity utilizing SONET capable
ring architecture, which has the ability to route customer traffic in either
direction around its ring design thereby assuring that fiber cuts do not
interrupt service to customers on the NY Network and its planned Intra-City
Networks. Currently, a state-of-the-art network operating system continuously
monitors and maintains quality control of the NY Network on a 24-hour basis and
alerts the Company of any degradation or loss of fiber capacity, pinpoints the
location of such degradation and enables the Company to repair or replace
impaired fiber without any loss of service. In addition, the monitoring system
automatically reroutes traffic in the event of a catastrophic break in the
system, enabling the Company to ensure that its customers obtain continuous
service.

FRANCHISE, LICENSE AND RELATED AGREEMENTS

NEW YORK CITY FRANCHISE AGREEMENT. The Company has entered into a 15 year
non-exclusive franchise agreement with New York City, which expires in December
2008, to install, operate, repair, maintain, remove and replace cable, wire,
fiber or other transmission medium that may be used in lieu of cable, wire or
fiber on, over and under the inalienable property of New York City in order to
provide telecommunications services which originate and/or terminate in or
transit New York City. The NYC Franchise Agreement provides that the Company may
submit a written petition to New York City to renew the term of the franchise at
least 12 months (but not more than 18 months) before the expiration of the 15
year term. However, New York City has no obligation to renew the NYC Franchise
Agreement. The City of New York has granted only seven franchises to date.
However, the Company is not aware of any limit on the number of franchises that
the City of New York may grant and believes that the City of New York may be in
the process of granting at least three additional licenses. See "Risk Factors --
Risk of Cancellation or Non-Renewal of Franchises, Licenses or Permits."

The NYC Franchise Agreement requires the Company to provide New York City
with certain telecommunications infrastructure and to complete construction of
its initial network as described in the NYC Franchise Agreement by November
1997. The Company believes it is on schedule to complete such construction.

Both New York City and the Company have the right, at any time after
December 20, 2000, upon six months notice, to renegotiate certain terms of the
NYC Franchise Agreement, including the annual compensation payable by the
Company to New York City, based on changes in technological, regulatory or
market conditions which may occur after the effective date of the NYC Franchise
Agreement. In the event either party calls for renegotiation, both New York City
and the Company are required to negotiate any such changes in good faith. In the
event an agreement cannot be reached upon any such renegotiation, the NYC
Franchise Agreement will be subject to early termination on a date which would
be one half of the number of days between the date of the notice to renegotiate
and January 1, 2009.

The Company was required to pay the City of New York an annual franchise fee
at a rate of 10% of Gross Revenues per year for 1995 and 1996, currently pays 6%
of Gross Revenues in 1997 and will pay

32
<PAGE>
5% of Gross Revenues for each remaining year of the franchise. "Gross Revenues"
is defined in the NYC Franchise Agreement as all revenues received directly or
indirectly by the Company or any affiliate of the Company from or in connection
with telecommunications services which originate in, terminate in, or transit
New York City. Revenues that are generated from transmissions which transit New
York City, but also include transmission through other areas, are to be
pro-rated. The minimum franchise fee payable to City of New York is $200,000 per
annum.

CONDUIT OCCUPANCY AGREEMENT. The Company entered into a non-exclusive
conduit occupancy agreement (the "Conduit Occupancy Agreement") with NYNEX in
May 1993, authorizing the Company to install its cable facilities in NYNEX's
conduit system in New York. The Company is required to pay NYNEX certain rates
and charges pursuant to the terms of the agreement.

The Conduit Occupancy Agreement, which had an initial term of 12 months but
was to continue indefinitely if not affirmatively terminated by either party, is
terminable without cause by either party upon three months' written notice.
Under certain circumstances, a petition may be brought to the Public Services
Commission requesting that it decide a dispute arising over termination prior to
the termination of the Conduit Occupancy Agreement.

SERVICES

Market research estimates today's worldwide internetworking market at
approximately $27 billion. Recognizing the significant growth in this area as a
result of the ongoing expansion of corporate enterprise networks and the
proliferation of the Internet, MFN plans to use its fiber optic infrastructure
as a platform to expand into the business of providing SONET- based and
ATM-based broadband communications services aimed at the carrier market and high
end corporate/government users.

MFN has reserved sufficient dark fiber capacity to provide the
infrastructure which will allow the Company to offer the following services at
competitive rates:

- OC-3 through OC-192 resilient SONET networks

- High capacity ATM-based intranet services

- ATM-based Frame Relay transmission capacities

SALES AND MARKETING

The Company's sales and marketing strategy includes (i) positioning itself
as the communications carriers' carrier of choice, (ii) focusing on high dollar
volume corporate and government customers and (iii) emphasizing the cost
advantages which will allow the Company to lease its fiber optic infrastructure
at fixed prices which represent potentially significant savings for its large
volume carrier and corporate customers relative to their present build or buy
alternatives. The Company also believes that communications carriers and
corporate and government customers will be attracted to the Company's dark fiber
product and its unmetered pricing structure. The Company intends to focus its
sales and marketing efforts on carrier customers. However, the Company is
currently in the process of hiring additional sales professionals to focus on
both customer groups. As MFN constructs fiber optic networks in new cities,
local sales professionals are expected to be hired to target regional corporate
and government customers, while New York City based sales professionals will
seek out the Company's carrier customers.

CUSTOMERS

The Company currently has contracts with approximately 14 customers.

CARRIERS. The Company expects that communications carriers will account for
a majority of its business. The Company currently targets the major carriers,
such as resellers, data services, RBOCs, IXCs, CLECs, ISPs, wireless providers,
and major information service providers. The Company believes

33
<PAGE>
it can compete effectively with other providers due to its rapid deployment,
pricing, reliability, customer service and capacity of the MFN Network. The
Company traditionally leases dark fiber to communications carriers, providing
them with point-to-point and IXC POP-to-end user non-switched access which
connects their customers to the Company's network, enabling IXCs to eliminate or
reduce costly access charges.

The Company has entered into contracts with several communications carriers,
including providers of wireless and cellular services and a CLEC, as described
below. In addition, the Company is currently in the process of negotiating
agreements with certain other major communications carriers and will continue to
target such carriers in the future. However, there can be no assurance that such
agreements will be consummated or will be on terms as favorable to the Company
as are the existing agreements.

On June 3, 1997, the Company entered into an agreement with a CLEC that
provides certain exclusive long-term rights to the NY Network. The agreement
calls for MFN to provide the customer with capacity over a significant portion
of MFN's network at specified locations for twenty years (the "Term"), with an
additional ten year option exercisable by the customer. In addition, the
agreement permits the carrier to use additional fiber miles for additional
charges and requires, under certain circumstances, the Company to construct and
maintain extensions of up to two miles from the then-existing network. As
compensation through the Term, the Company is to receive $11.0 million ($5.0
million of which has been received by the Company) in scheduled upfront
payments, a monthly recurring charge per terminated fiber strand terminating at
certain additional locations, and an additional fiber charge per mile of
additional fiber made available for the customer. Charges for the term of the
option period are to be determined at market rates.

CORPORATE/GOVERNMENT CUSTOMERS. The Company expects that its corporate and
government customers, including members of the international financial and
commercial community, will primarily be entities with multiple locations and
high volume communications requirements. The Company expects to provide these
customers with dedicated point-to-point communications that have the capacity to
carry a wide range of communications services (E.G., high speed intranet
access). The Company offers its high-bandwidth services to such customers at
prices that are lower than those currently offered by regulated CLECs and ILECs.
However, the Company's customers currently provide their own transmission or
switching equipment.

The Company believes it can effectively compete for corporate and government
customers based upon price, non-metered usage, reliability and solutions
tailored to the customers' needs. In addition, the Company's NY Network
utilizes, and the Intra-City Networks will utilize, SONET technology and offer
reliability which the Company believes is generally superior to that provided by
the ILECs.

The Company currently has dark fiber infrastructure leasing arrangements
with a variety of financial services firms, including investment and commercial
banks, securities and accounting firms and a financial exchange, although
installation of the dark fiber to be leased pursuant to certain of the contracts
has not yet been completed by the Company. Accordingly, some of such contracts
are currently terminable and the terms of certain contracts will not commence
until the relevant dark fiber has been installed by the Company and accepted by
the relevant customers. There can be no assurance that the Company will complete
the installation in a timely manner. See "Risk Factors--Risks Associated with
Growth Strategy; Management of Expansion."

COMPETITION

Fiber optic systems are currently under construction both locally and
nationally. In New York City, for example, seven franchisees have been granted
the right to install and operate a telecommunications network within the city.
Development of fiber optic networks is also continuing on a national scale; for
example, one provider of fiber is currently in the midst of constructing a
cross-continental long distance

34
<PAGE>
fiber optic network from Los Angeles to New York and another is constructing a
fiber-based national backbone network which will connect 92 metropolitan areas
and span approximately 13,000 miles.

The construction of these networks enables their owners to either lease
access to their networks to other communications carriers or large corporate or
government customers seeking high bandwidth capacity, without these customers
having to incur costly expenditures associated with building networks of their
own. Alternatively, some network owners may choose to use their infrastructure
to provide switched voice and data services, competing directly with ILECs and
IXCs. Currently, MFN does not provide such services or plan to provide such
services.

In New York City and the cities where MFN plans to deploy fiber optic
communications networks, the Company faces significant competition from the
ILECs, which currently dominate their local communications markets. The Company
also faces competition from CLECs and other potential competitors in New York
City and will face competition in the cities in which the Company plans to build
its networks. Many of the Company's competitors have financial, management and
other resources substantially greater than those of the Company, as well as
other competitive advantages over the Company, including established reputations
in the communications market.

Various communications carriers already own fiber optic cables as part of
their communications networks. Accordingly, each of these carriers could, and
some do, compete directly with the Company in the market for leasing fiber
capacity. In addition, although CLECs generally provide a wider array of
services to their customers than the Company presently provides to its
customers, CLECs nevertheless represent an alternative means by which a
potential customer of the Company could obtain direct access to an IXC POP or
other site of the customer's choosing. Thus, CLECs could compete with the
Company.

Some communications carriers and local cable companies have extensive
networks in place that could be upgraded to fiber optic cable, as well as
numerous personnel and substantial resources to undertake the requisite
construction to so equip their networks. To the extent that communications
carriers and local cable companies decide to equip their networks with fiber
optic cable, they are potential direct competitors of the Company provided that
these competitors are willing to offer this capacity to all of their customers.
See "Risk Factors--Competitive Industry."

The Company believes that as competition in the local exchange market
develops, a fundamental division between the needs of corporate, governmental
and institutional end users and residential end users will drive the creation of
differentiated communications services and service providers. The Company
believes that the IXCs, ISPs, wireless carriers and corporate and government
customers on which it focuses will have distinct requirements, including maximum
reliability, consistent high quality transmissions, capacity for high-speed data
transmissions, diverse routing and responsive customer service. The Company
believes that it will be able to satisfy the needs of such customers.

PROPERTIES

The NY Network and its component assets are the principal properties
currently owned by the Company. The Company owns substantially all of the
communications equipment required for its business. The Company's installed
fiber optic cable is laid under the various rights-of-way held by the Company.
See "--Build-out of Networks--Rights-of-Way". Other fixed assets are located at
various leased locations in geographic areas served by the Company.

The Company's executive, administrative and sales offices are located at its
principal office in New York, New York. MFN leases this space from 110 East 42nd
Street Associates, a limited partnership, an affiliate of Metromedia, at market
rates under two agreements that expire in April and June 1998, respectively. The
Company leases additional space at 60 Hudson Street, New York, New York from
Hudson Telegraph Associates. See "Certain Relationships and Related
Relationships."

35
<PAGE>
REGULATION

On February 8, 1996, the 1996 Act, the most comprehensive reform of the
nation's telecommunications laws since the Communications Act, was enacted. The
1996 Act has resulted in substantial changes in the marketplace for
communications services that should be largely favorable to the Company.

FEDERAL

The 1996 Act imposes a number of access and interconnection requirements on
all local exchange providers, including CLECs, with additional requirements
imposed on ILECs. The 1996 Act provides a detailed list of items which are
subject to these interconnection requirements, as well as a detailed set of
duties for all affected carriers. All LECs, including CLECs, have a duty to (i)
not unreasonably limit the resale of their services, (ii) provide number
portability if technically feasible, (iii) provide dialing parity to competing
providers, (iv) provide access to poles, ducts and conduits and (v) establish
reciprocal compensation arrangements for the transport and termination of
tele-communications. In addition to those general duties of all LECs, ILECs have
additional duties to (i) interconnect at any technically feasible point and
provide service equal in quality to that provided to their customers or the ILEC
itself, (ii) provide unbundled access to network elements at any technically
feasible point, (iii) offer retail services at wholesale prices for the use of
competitors, (iv) provide reasonable public notice of changes in the network or
the information necessary to use the network and (v) provide for physical
collocation. "Physical collocation" is an offering by an ILEC that enables
another telecommunications carrier to enter the ILEC's premises to install,
maintain and repair its own equipment that is necessary for interconnection or
access to the ILEC's network elements. An ILEC must allocate reasonable amounts
of space to carriers on a first-come first-served basis. If space limitations or
practical or technical reasons prohibit physical collocation, an ILEC must offer
"virtual collocation," by which the other carrier may specify ILEC equipment to
be dedicated to its use and electronically monitor and control communications
terminating in such equipment.

The FCC adopted pricing and other guidelines to implement the
interconnection provisions of the 1996 Act, but the 8th Circuit Court of Appeals
recently vacated most of the FCC's guidelines. The responsibility for setting
pricing and other guidelines with respect to interconnection has thus been left
up to the individual state public service commissions. It is expected that
varying pricing and guidelines will emerge from state to state, and some of
these guidelines may eventually have an indirect adverse effect on the Company's
business.

Federal telecommunications law imposes special legal requirements on "common
carriers." The Company believes that it does not provide any services on a
common carrier basis and therefore is not subject to the common carrier
regulations of the FCC or to the common carrier provisions of the Communications
Act. Federal telecommunications law also imposes special legal requirements on
"communications carriers." Presently, the law is unclear as to whether a
provider of dark fiber such as the Company is a "telecommunications carrier".
The FCC has been asked to clarify the status of dark fiber providers, and if the
agency decides that such companies are communications carriers, then the Company
would be subject to certain additional regulatory requirements. The extent to
and manner in which the Company provides telecommunications services will
influence whether it is subject to FCC regulation as a common carrier and/or a
telecommunications carrier, like the ILECs and the CLECs. In such a case, and
particularly if the Company's dark fiber leasing business also becomes subject
to regulation, the Company will almost certainly lose the competitive advantages
associated with being a relatively unregulated entity. Presently, however, the
Company is relatively unencumbered by federal

36
<PAGE>
telecommunications laws. This competitive advantage may be eroded at any time if
the Company were to begin offering telecommunications services on a common
carrier basis or if any of the regulatory rules or policies applicable to the
Company were to change.

STATE

The 1996 Act prohibits state and local governments from enforcing any law,
rule or legal requirement that prohibits or has the effect of prohibiting any
person from providing any interstate or intrastate telecommunications service.
Notwithstanding the prohibition contained in the 1996 Act, states regulate
telecommunications services, including through certification of providers of
intrastate services, regulation of intrastate rates and service offerings, and
other regulations. Nonetheless, this provision of the 1996 Act should enable the
Company and customers of the Company to provide telecommunications services in
states that previously prohibited competitive entry.

States retain jurisdiction under the 1996 Act to adopt regulations necessary
to preserve universal service, protect public safety and welfare, ensure the
continued quality of communications services and safeguard the rights of
consumers. States are also responsible for mediating and arbitrating CLEC-ILEC
interconnection arrangements if voluntary agreements are not reached.
Accordingly, the degree of state involvement in local telecommunications
services may be substantial.

In arbitrating interconnection agreements under the 1996 Act between ILECs
and their potential competitors, some state commissions have considered whether
dark fiber should be considered an unbundled network element. For example, the
New York Public Service Commission determined that it would not require NYNEX to
provide dark fiber as an unbundled network element. State commissions, including
those in Florida, Maryland, North Carolina, and Virginia, also have either
refused to require the ILECs to offer dark fiber to competitors, or have stated
that the issue would be addressed at a later time. On the other hand, state
commissions in Illinois, Massachusetts, Arizona, Georgia, Minnesota, Ohio,
Oregon and Tennessee have found dark fiber to be a network element and required
the ILECs to offer it on an unbundled basis to CLECs. There can be no assurance
that these requirements, and the associated pricing methodologies, where
applicable, will not reduce the demand for dark fiber provided by the Company.

The Company believes that it is not subject to regulation as a
telecommunications carrier by state commissions in Illinois, New York,
Pennsylvania, or the District of Columbia. However, whether a provider of dark
fiber is subject to the jurisdiction of regulatory commissions in these states
is uncertain. In addition, the extent to and manner in which the Company
provides telecommunications services will influence whether it is subject to the
same state regulations that are imposed on ILECS and CLECs. If the Company does
become subject to state regulation it could lose the competitive advantages
associated with being a relatively unregulated entity. There can be no assurance
that a state commission will not exercise jurisdiction over the Company's
business. State regulation affects market conditions for the services of the
Company and its customers, and thus affects the Company's business.

In response to the 1996 Act, NYNEX "unbundled" its local loop in October
1996. As a result, carriers such as the Company will be permitted to access
NYNEX's existing wiring infrastructure in buildings on an economical basis,
which the Company believes enhances the strategic value of the NY Network to
potential customers. By virtue of the unbundling, NYNEX must make a significant
portion of its in-house apartment wiring available for $2 per month per
apartment. The availability of an unbundled local loop will enable new carriers
to enter the residential voice market on a competitive basis with NYNEX.

LOCAL

INTERNATIONAL

Various regulatory requirements and limitations also will influence the
Company's business as it attempts to enter international markets.

EMPLOYEES

As of June 30, 1997, the Company employed 26 people. The Company's employees
are not represented by any labor union. The Company considers its relationship
with employees to be good.

LEGAL PROCEEDINGS

On or about April 18, 1997, Howard Katz, Realprop Capital Corp. and Evelyn
Katz commenced an action against, among others, the Company and Stephen A.
Garofalo in the United States District Court for the Southern District Court of
New York captioned KATZ, ET AL. v. NATIONAL FIBER NETWORK, INC., ET AL., No. 97
Civ. 2764 (JGK) (the "Katz Litigation"). (National Fiber Network, Inc. is the
former name of the Company). On May 28, 1997, the plaintiffs filed an amended
complaint. The amended complaint alleges causes of action for, among other
things, common law fraud, violations of Section 10(b) of the Securities Exchange
Act of 1934 and Rule 10b-5 promulgated thereunder, breach of fiduciary duty and
negligent misrepresentation for alleged misrepresentations and omissions made in
connection with the repurchase of the Katz Securities (as defined below under
"Certain Relationships and Related Transactions"). The amended complaint also
contains allegations of corporate waste against the Company and Mr. Garofalo.
Plaintiffs seek, among other things, compensatory damages of not less than $4.5
million,

38
<PAGE>
unspecified punitive damages and, in the alternative, rescission. On June 11,
1997, various defendants, including the Company and Stephen A. Garofalo moved to
dismiss the amended complaint. The Company intends to vigorously defend itself
against these allegations based on its belief that MFN acted appropriately in
connection with the matters at issue in this litigation. No assurance can be
made, though, that the Company will not determine that the advantages of
entering into a settlement outweigh the risks and expense of protracted
litigation or that ultimately the Company will be successful in its defense of
the allegations.

In addition, the Company is subject to various claims and proceedings in the
ordinary course of business. Based on information currently available, the
Company believes that none of such current claims, or proceedings, individually
or in the aggregate, including the Katz Litigation, will have a material adverse
effect on the Company's financial condition or results of operations, although
there can be no assurances in this regard.

1997 STOCK INCENTIVE PLAN

In connection with the consummation of the Offerings the Company intends to
adopt the Metromedia Fiber Network, Inc. 1997 Incentive Stock Plan (the "1997
Incentive Stock Plan"). The following is a summary of the material features of
the 1997 Incentive Stock Plan.

The purpose of the 1997 Incentive Stock Plan is to give MFN a significant
advantage in retaining key employees, officers and directors, and to provide an
incentive to selected key employees, officers and directors of MFN who have
substantial responsibility in the direction of MFN, and others whom the
Committee (as defined below) determines provide substantial and important
services to MFN, to acquire a proprietary interest in MFN, to continue as
employees, officers and directors or in their other capacities, and to increase
their efforts on behalf of MFN.

TYPES OF AWARDS

The types of awards that may be granted pursuant to the 1997 Incentive Stock
Plan include (i) incentive stock options ("ISOs") and (ii) non-qualified stock
options ("NQSOs" and together with ISOs, "Stock Options" and "Awards"). ISOs are
intended to be treated as incentive stock options within the meaning of Section
422 of the Code. NQSOs are, in general, options which do not have the special
income tax advantages associated with ISOs. Stock Option grants will consist of
the maximum number of ISOs that may be granted to a particular grantee under
applicable law with the balance of the Stock Options being NQSOs.

ADMINISTRATION OF THE PLAN

The 1997 Incentive Stock Plan will be administered by the Compensation
Committee of the Board (the "Committee"). The Committee will consist of two or
more members of the Board each of whom shall be an "outside director" as defined
under Section 162(m) of the Code, and the regulations and interpretations
thereunder. Members of the Committee will be eligible to receive certain Awards
(other than ISOs) under the 1997 Incentive Stock Plan.

Subject to the terms and conditions of the 1997 Incentive Stock Plan and the
formula awards for Independent Directors (as defined below), the Committee is
authorized to grant Awards, to determine which employees, officers, directors or
other individuals may be granted Awards, to determine the type

45
<PAGE>
and number of Awards to be granted, to determine the term of such Awards, to
determine the exercise price of any Award, to determine the terms of any
agreement pursuant to which Awards are granted, to interpret and construe the
1997 Incentive Stock Plan, and to determine any other matters delegated to it
under the 1997 Incentive Stock Plan or necessary for the proper administration
of the 1997 Incentive Stock Plan.

SHARES OF CLASS A COMMON STOCK SUBJECT TO THE 1997 INCENTIVE STOCK PLAN

Subject to certain exceptions set forth in the 1997 Incentive Stock Plan,
the aggregate number of shares of the Class A Common Stock that may be the
subject of Awards under the 1997 Incentive Stock Plan is . The maximum
number of shares of Class A Common Stock available with respect to Awards
granted to any one grantee shall not exceed, in the aggregate, . Shares of
Class A Common Stock granted under the 1997 Incentive Stock Plan may either be
authorized but unissued shares of Class A Common Stock not reserved for any
other purpose or shares of Class A Common Stock held in or acquired for the
treasury of MFN.

Shares of Class A Common Stock subject to an Award which terminates
unexercised may again be the subject to an Award under the 1997 Incentive Stock
Plan. In addition, shares of Class A Common Stock surrendered to MFN in payment
of the exercise price or applicable taxes upon exercise or settlement of an
Award may also be used thereafter for additional Awards.

ELIGIBILITY

Any key employee, officer and director, including a director who is not an
employee and a director who serves on the Committee, of MFN and its subsidiaries
who has substantial responsibility in the direction of MFN and its subsidiaries
and anyone else whom the Committee determines provides substantial and important
services to MFN is eligible to receive Awards.

Any Independent Director who first serves on the Board subsequent to the
date the 1997 Incentive Stock Plan was adopted shall be entitled to receive
Awards under the 1997 Incentive Stock Plan with respect to shares of
Common Stock, each having an exercise price equal to the fair market value of a
share of Class A Common Stock on the date of grant. For purposes hereof,
"Independent Directors" shall mean any member of the Board who during his entire
term as a director was not employed by MFN and its subsidiaries, within the
meaning of Section 424(f) of the Internal Revenue Code of 1986, as amended (the
"Code"), and who also satisfies the criteria for "outside director" under
Section 162(m) of the Code.

TERMS AND CONDITIONS OF STOCK OPTIONS

The exercise price of all ISOs granted under the 1997 Incentive Stock Plan
is the fair market value of the Class A Common Stock on the date of grant. The
exercise price of all NQSOs granted under the 1997 Incentive Stock Option Plan
will be determined by the Committee, although the initial awards will be made at
fair market value of the Class A Common Stock on the date of grant. The term of
each Stock Option granted under the 1997 Incentive Stock Plan will be determined
by the Committee but will in no event be greater than ten years from the date of
grant.

With respect to ISOs granted to a grantee who owns stock possessing more
than 10% of the voting rights of MFN's outstanding capital stock on the date of
grant, the exercise price of the ISO shall be equal to 110% of the fair market
value of the Class A Common Stock subject to the ISO on the date of grant and
the ISO may not be exercisable more than five years after the date of grant.

Stock Options shall vest and become exercisable over a period of years as
determined by the Committee.

46
<PAGE>
Subject to the following sentence, upon the exercise of a Stock Option, the
grantee must pay the exercise price in cash. At the discretion of the Committee,
the exercise price may be paid with shares of Class A Common Stock already owned
by, and in possession of, the grantee or in a combination of cash or shares of
Class A Common Stock.

The aggregate fair market value of the Class A Common Stock (determined on
the date of grant) for which ISOs granted under the 1997 Incentive Stock Plan
and any other plan of MFN or a subsidiary may be exercisable for the first time
by any grantee during any calendar year cannot exceed $100,000 or such other
amount as may be prescribed under the Code or applicable regulations and rulings
from time to time.

ACCELERATION OF VESTING AND EXERCISABILITY

If a grantee's employment with MFN is terminated because of the grantee's
death, the grantee's retirement on or after attaining age sixty-five or a Change
in Control prior to the date of the Stock Option is by its terms exercisable,
the Stock Option shall be immediately exercisable (and the restrictions thereof,
if any, shall lapse) as of the date of the termination of the grantee's
employment, subject to the other terms of the 1997 Incentive Stock Plan.

Upon a Change in Control of MFN, (i) each holder of a Stock Option shall
have the right to exercise the Stock Option in full without regard to any
waiting period, installment period or other limitation or restriction thereon
and (ii) each holder of a Stock Option shall have the right, exercisable by
written notice to MFN within sixty days after the Change in Control, to receive,
in exchange for the surrender of the Stock Option or any portion thereof to the
extent the Stock Option is then exercisable in accordance with clause (i), an
amount of cash equal to the difference between the fair market value of the
Class A Common Stock on the date of exercise and the exercise price of the Stock
Option.

In general, under the 1997 Incentive Stock Plan, a "Change in Control" of
MFN shall be deemed to have occurred as of the first day any one or more of the
following four conditions have been satisfied: (i) any event whereby a Person
(other than (a) MFN or an affiliate, as defined in the Exchange Act or (b) any
employee benefit plan or trust sponsored or maintained by MFN or an affiliate,
as defined in the Exchange Act) (x) acquires 35% or more of MFN's outstanding
voting securities, (y) acquires securities of MFN bearing a majority of voting
power with respect to election of directors of MFN or (z) acquires all or
substantially all of MFN's assets, whether by sale, lease, exchange or other
transfer (in one transaction or in a series of related transactions); (ii) a
change in the composition of the Board such that at any time a majority of the
Board shall not have been members of the Board for twenty-four months; provided,
however, that directors who were appointed or nominated for election by at least
two-thirds of the directors who were directors at the beginning of such
twenty-four month period (or deemed to be such directors under this clause (ii))
shall be deemed to be directors at the beginning of such twenty-four month
period for the purposes of this clause (ii); (iii) the stockholders of MFN
approve any plan or proposal for the liquidation or dissolution of MFN; or (iv)
any consolidation or merger of MFN, other than a merger or consolidation of MFN
in which the voting securities of MFN outstanding immediately prior thereto
continue to represent (either by remaining outstanding or by being converted
into voting securities of the surviving entity) at least 50% of the combined
voting power of the voting securities of MFN or such surviving entity
outstanding immediately after such merger or consolidation. "Person" shall have
the same meaning as ascribed to such term in Section 3(a)(9) of the Exchange Act
and used in Section 13(d) thereof.

ADJUSTMENT PROVISIONS

The total number and character of shares of Class A Common Stock subject to
Awards and the number and character of shares of Class A Common Stock subject to
outstanding Awards and/or the exercise price of such shares will be
appropriately adjusted by the Committee if the shares of Class A

47
<PAGE>
Common Stock are changed into or exchanged for a different number or kind of
shares of stock or other securities of MFN or of another corporation (whether by
reason of merger, consolidation, recapitalization, reclassification, split,
reverse split, combination of shares, or otherwise). The Committee may also make
appropriate adjustments in the event of a merger, consolidation or other
transaction or event having a similar event.

AMENDMENT AND TERMINATION OF THE 1997 INCENTIVE STOCK PLAN

Unless terminated earlier by action of the Board of MFN, the 1997 Incentive
Stock Plan will terminate on the tenth anniversary of its adoption, and no
additional grants under the 1997 Incentive Stock Plan will be made after that
date.

The Board may amend or terminate the 1997 Incentive Stock Plan at any time,
but may not, without the written consent of the grantee, make any such
alteration which would impair the rights of a holder of an outstanding Award.
Furthermore, the 1997 Incentive Stock Plan may not be amended without the
approval of the holders of a majority of the outstanding stock of MFN (i) to
decrease the minimum exercise price for ISOs; (ii) to extend the term of the
1997 Incentive Stock Plan beyond ten years, (iii) to extend the maximum terms of
the Awards granted beyond ten years, (iv) to withdraw the administration of the
1997 Incentive Stock Plan from the Committee, (v) to change the class of
eligible employees, officers, directors and other grantees, (vi) to increase the
aggregate number of shares of Class A Common Stock authorized to be issued, and
(vii) to otherwise require stockholder approval to comply with Rule 16b-3 or any
other applicable law, regulation, or listing requirement or to qualify for an
exemption or characterization that is deemed desirable by the Board. No
amendment or terminations of the 1997 Incentive Stock Plan shall, without
written consent of the grantee, alter the terms of Awards already granted and
such Stock Options shall remain in full force and effect as if the 1997
Incentive Stock Plan had not been terminated.

MODIFICATION, EXTENSION AND RENEWAL OF OPTIONS

The Committee may, within the limitations of the Incentive Stock Plan,
modify, extend or renew outstanding Awards granted under the 1997 Incentive
Stock Plan, or accept the surrender of outstanding Awards and authorize the
granting of new Awards in substitution therefor. No modification may, without
the consent of the grantee, alter or impair any rights or obligations under any
Award theretofore granted to the grantee nor shall any modification adversely
affect the status of an ISO under Section 422 of the Code.

TRANSFERABILITY OF AWARDS AND OTHER PROVISIONS

The rights of a grantee with respect to the Awards granted pursuant to the
1997 Incentive Stock Plan are not transferable other than by will or the laws of
descent and distribution and are exercisable, during the lifetime of the
grantee, only by the grantee or by the guardian or legal representative of the
grantee acting in a fiduciary capacity on behalf of the grantee under state law
or court supervision. An Award is not subject, in whole or in part, to
attachment, execution or levy of any kind.

RIGHTS UPON TERMINATION OF EMPLOYMENT

If the grantee dies while an employee or when no longer an employee but
while he or she still has the right to exercise an Award, the grantee's estate
shall have the right for a period of one year following the date of death to
exercise the Award to the extent such Award is exercisable and to the extend
such Award has not yet expired.

Upon a grantee's retirement from MFN or a subsidiary on or after attaining
age sixty-five the grantee shall have the right for a period of three months
following the date of retirement to exercise an Award to the extent such Award
is exercisable and to the extent such Award has not yet expired.

48
<PAGE>
Upon a grantee's termination of employment from MFN on account of
disability, the grantee or the legal representative of the grantee, shall have
the right for a period of one year following the date of such termination to
exercise an Award to the extent such award is exercisable and to the extent such
Award has not yet expired.

In the event the grantee's employment with MFN or a subsidiary is terminated
for any reason other than disability, death or retirement on or after attaining
age sixty-five, the grantee may exercise an Award within three months after his
or her termination of employment.

RIGHTS AS STOCKHOLDER

No grantee of any Stock Option has any rights as a stockholder with respect
to any shares of Common Stock subject to his or her Stock Option prior to the
date on which he or she is recorded as the holder of such shares of Class A
Common Stock on the records of MFN.

RIGHT TO CONTINUED EMPLOYMENT

The 1997 Incentive Stock Plan is not a contract of employment, and the terms
of employment of any grantee shall not be affected in any way by the 1997
Incentive Stock Plan or related instruments except as specifically provided
therein. The establishment of the 1997 Incentive Stock Plan shall not be
construed as conferring any legal rights upon any grantee for a continuation of
employment, nor shall it interfere with the right of MFN or any subsidiary to
discharge any grantee and to treat him or her without regard to the effect which
such treatment might have upon him or her as a grantee.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

HISTORICAL TRANSACTIONS

Stephen A. Garofalo, the Company's Chairman of the Board, Chief Executive
Officer and a principal stockholder, served as chief executive officer and
principal stockholder of F. Garofalo Electric Co., Inc. ("Garofalo Electric").
Garofalo Electric provided the Company with electrical contracting services in
connection with the installation of the Company's fiber optic network. As of
December 31, 1995, the Company owed Garofalo Electric $692,887 for such
services. The Company believes that the terms pursuant to which such services
were rendered to the Company by Garofalo Electric were fair to the Company and
comparable to those which could have been obtained in arm's-length negotiations
with unaffiliated parties. On July 24, 1995, Garofalo Electric assigned to the
Company its interest in an agreement between Garofalo Electric and Oppenheimer
Capital for the provision of dark fiber. In May 1996, the Company, Garofalo
Electric and Frank Garofalo, the assignee of Garofalo Electric's receivable from
the Company and the father of Stephen A. Garofalo, entered into an agreement
whereby the full amount was satisfied by the issuance of 900,000 shares of Class
A Common Stock to Frank Garofalo. Garofalo Electric is currently in the process
of winding up its business and affairs.

Stephen A. Garofalo has made various loans to the Company. During 1994, such
loans totaled $1,967,109. In April 1995 Mr Garofalo agreed to contribute to the
Company's capital $1.7 million of amounts due him. By agreement between the
Company and Mr. Garofalo in May 1996 the transaction was rescinded. During 1995,
the Company made repayments (net of additional advances) of $1,070,130. The
loans from Mr. Garofalo totaled approximately $896,979 at December 31, 1995. On
May 21, 1996, the Company issued to Mr. Garofalo 300,000 shares of Class A
Common Stock in satisfaction of $600,000 of the outstanding balance. All
outstanding amounts have been repaid to Mr. Garofalo.

As of December 31, 1996, the Company had outstanding approximately $4.9
million of indebtedness due to US ONE Communications of New York, Inc. ("US
ONE"), a lessee of the Company's dark fiber, which was personally guaranteed by
Stephen A. Garofalo. On April 30, 1997, upon consummation of the Metromedia
Investment, a portion of the indebtedness was converted into a prepaid lease
payment to the Company with the remainder paid in cash from proceeds of the
Metromedia Investment.

On March 16, 1995, the Company entered into a loan agreement (the "Rubin
Loan Agreement") with Robert Rubin, at the time a Director of the Company,
pursuant to which the Company borrowed $500,000 at an interest rate of 10% per
annum and issued to Mr. Rubin 307,680 shares of Class A Common Stock as an
inducement for entering into the agreement. The Rubin Loan Agreement had a term
of one year and the obligations of the Company were (i) guaranteed by Stephen A.
Garofalo and (ii) collateralized by shares of Common Stock owned by Mr.
Garofalo. The Rubin Loan Agreement, including all accrued interest, was fully
repaid in March 1996.

On January 12, 1996, the Company entered into an agreement with its then
legal counsel, Silverman, Collura, Chernis & Balzano, P.C. ("SCCB"), pursuant to
which the Company agreed to issue shares of Class A Common Stock as additional
consideration for legal services provided to the Company. Pursuant to this
agreement, and a subsequent amendment dated April 16, 1996, the Company issued
to SCCB 968,649 shares of Class A Common Stock during March and April of 1996.
At the time of the April 16 amendment, Peter Silverman, a partner of SCCB, was a
Director of the Company. On June 15, 1996, the Company granted SCCB a warrant to
purchase an aggregate of 300,000 shares of Class A Common Stock at an exercise
price of $.033 per share as additional consideration for legal services provided
to the Company. In January 1997, SCCB exercised this warrant and purchased
300,000 shares of Class A Common Stock.

In February, 1996, the Company entered into a settlement agreement (the
"Katz Settlement Agreement") with Howard Katz, the Company's former Chief
Financial Officer, and Realprop Capital Corp.

51
<PAGE>
("Realprop"), an affiliate of Mr. Katz, in connection with the termination of
Mr. Katz's employment with the Company. Pursuant to the Katz Settlement
Agreement, the Company agreed to pay Mr. Katz approximately $940,000 over a
period of five years. On November 14, 1996, Howard Katz, Lauren Katz, Stephen
Katz and Realprop (collectively, the "Katz Group") entered into an agreement
(the "Katz Purchase Agreement") with Peter Sahagen, at the time acting Vice
Chairman of Finance of the Company, pursuant to which Mr. Sahagen was granted
the right to purchase an aggregate of 521,955 shares of Class A Common Stock and
an option to purchase warrants for the purchase of 410,025 shares of Class A
Common Stock (collectively, the "Katz Securities") for an aggregate purchase
price of $640,000. In conjunction with the Katz Purchase Agreement, Howard Katz
and Realprop Capital Corp. agreed to release the Company from all liabilities
and obligations arising out of the Katz Settlement Agreement, and to reduce the
term of a $90,000 per year consulting agreement (the "Consulting Agreement")
from five years to three years. On February 11, 1997, Mr. Sahagen entered into a
letter agreement with the Company acknowledging that he was acting as nominee
for the Company with respect to the Katz Purchase Agreement and assigned to the
Company all of his rights, title and interest in and to the Katz Purchase
Agreement. The Company agreed to reimburse Mr. Sahagen for $25,000 in payments
made to Mr. Katz for extending Mr. Sahagen's right to purchase the Katz
Securities. On February 11, 1997, the Company entered into an agreement with the
Katz Group, pursuant to which the Company purchased the Katz Securities for
$640,000 and confirmed that the Consulting Agreement may be terminated by the
Company after three years of its term had concluded. The purchase price was
funded with a portion of the proceeds of the Metromedia Loan (as described
below). The foregoing transaction is the subject of a pending lawsuit. See
"Business--Legal Proceedings."

On April 15, 1996, the Company entered into an employment agreement with
Gerald Vento pursuant to which Mr. Vento would serve as Chief Executive Officer
of the Company. On the same day, the Company entered into a stock purchase
agreement and a consulting agreement with Vento & Company of New York, LLC
("VCNY"). Pursuant to the stock purchase agreement, the Company issued 3,000,000
shares of Class A Common Stock to VCNY as consideration for prior services
provided by VCNY. On October 9, 1996, the Company entered into a settlement
agreement with Mr. Vento and VCNY. Pursuant to such settlement agreement, (i)
the Company and Mr. Vento agreed to terminate Mr. Vento's employment agreement,
(ii) VCNY agreed to sell to Stephen A. Garofalo 2,700,000 shares of Class A
Common Stock (the "Vento Shares") and (iii) the Company agreed to pay $112,500
to VCNY on behalf of Mr. Vento. On January 3, 1997, Mr. Garofalo assigned his
right to purchase the Vento Shares to Mr. Sahagen, who together with other
parties purchased the Vento Shares for $425,000.

On October 28, 1996, the Knobel 1995 Childrens' Investment Trust (the
"Knobel Trust") granted to Stephen A. Garofalo an option to purchase 788,736
shares of Class A Common Stock of the Company for an aggregate purchase price of
$500,000. By letter dated December 3, 1996, the option was amended to reduce the
number of option shares to 638,736. The option was thereafter assigned by Mr.
Garofalo to the Company. On February 11, 1997, the Company exercised the option
by payment of the sum of $500,000 to the Knobel Trust. Payment of such amount
was funded with a portion of the proceeds of the Metromedia Loan.

On February 11, 1997, the Company entered into an agreement (the "Sahagen
Agreement") with Mr. Sahagen. Pursuant to the Sahagen Agreement, (i) the Company
agreed to pay Mr. Sahagen a fee of $250,000 upon an equity investment in the
Company of at least $10 million, in full and complete payment for all services
provided to the Company by Mr. Sahagen and for any fees or compensation due to
Mr. Sahagen pursuant to any prior agreements with the Company, (ii) Mr. Sahagen
agreed to release the Company from any claims against the Company, subject to
payments required by the Sahagen Agreement, (iii) the Company agreed to
designate Mr. Sahagen or a suitable designee selected by Mr. Sahagen as a
Director of the Company for a term of six months and (iv) the Company granted
Mr. Sahagen certain "piggyback" registration rights. In connection with the
Metromedia Investment, the Company paid the $250,000 fee to Mr. Sahagen.

52
<PAGE>
On December 13, 1996, the Company issued and sold to Penny Lane Partners,
L.P. ("Penny Lane"), for aggregate cash consideration of $2,025,000, (i) 150,000
shares of 10% cumulative convertible preferred stock (the "Series A Preferred
Stock") bearing dividends at a rate of $1.35 per share per annum, (ii) warrants
to purchase 225,000 shares of Class A Common Stock at an exercise price of $2.50
per share (the "Penny Lane Warrants") and (iii) a contingent stock subscription
warrant to purchase a number of shares of Class A Common Stock (such number to
be determined based on certain future events) at an exercise price of $0.01 per
share (the "Contingent Warrants"). In connection with the Metromedia Investment,
Penny Lane agreed to permit the Series A Preferred Stock and the Contingent
Warrants to be redeemed at an aggregate redemption price of $2,115,000 (which
includes accrued but unpaid dividends on the Series A Preferred Stock) and in
connection therewith the number of shares underlying the Penny Lane Warrants was
increased from 225,000 to 450,000.

In 1994 the Company engaged Richard A. Eisner & Company, LLP ("Eisner") to
serve as its independent auditors. During 1995, Gerald Vento began his
affiliation with the Company and requested that the Company engage M.R. Weiser &
Co. LLP, Certified Public Accountants ("Weiser"), to serve as the Company's
independent auditors. Stephen A. Garofalo, majority stockholder and Chairman of
the Board, approved the dismissal of Eisner and the engagement of Weiser. In
September 1996, the Company decided to engage a "big six" accounting firm and
engaged Ernst & Young LLP ("Ernst & Young") to serve as its independent
auditors. Stephen A. Garofalo, majority stockholder, approved the dismissal of
Weiser and the engagement of Ernst & Young. At no time during the periods in
which Eisner and Weiser served as the Company's independent auditors were there
any disagreements between the Company and Eisner or Weiser regarding any matter
of accounting principles or practices, financial statement disclosure or
auditing scope or procedures. Both Eisner and Weiser included in their opinions
on the Company's financial statements a separate paragraph stating that there
was substantial doubt about the Company's ability to continue as a going
concern. Ernst & Young's report on the Company's consolidated financial
statements for the year ended December 31, 1996 does not contain a similar
statement.

RECENT TRANSACTIONS

METROMEDIA INVESTMENT. On February 10, 1997, Metromedia agreed to loan
$2,000,000 to the Company. See "Principal Stockholders." Pursuant to an
agreement dated March 6, 1997, Metromedia agreed to loan to the Company up to an
additional $6,000,000, subject to certain conditions (together with the loan on
February 10, the "Metromedia Loan"). On April 30, 1997, the Metromedia Loan was
repaid with a portion of the proceeds from the Metromedia Investment. The
Metromedia Loan was funded in two installments: (i) $1,140,000 on February 10,
1997 and (ii) $860,000 on February 14, 1997, and provided for a revolving loan
of up to an additional $6,000,000. The Metromedia Loan was scheduled to mature
on August 31, 1997 and bore interest at the prime rate announced by The Chase
Manhattan Bank. The proceeds from the first installment of the Metromedia Loan
were used to fund an escrow account which repurchased on behalf of the Company
386,897 shares of Class A Common Stock and warrants to purchase 136,675 shares
of Class A Common Stock (the "Repurchased Securities"). Pursuant to an escrow
arrangement, the Repurchased Securities were pledged to Metromedia as security
for the Metromedia Loan. The proceeds from the other installments of the
Metromedia Loan were used for working capital. On April 30, 1997, the Company
entered into the Metromedia Agreement, pursuant to which the Company sold to
Metromedia, Mr. Subotnick, Mr. Wadler and Ms. Kessel shares of the Series B
Preferred Stock (which constituted 100% of such series) for $32,500,000. The
shares of the Series B Preferred Stock were exchanged for 8,325,756 shares of
Class B Common Stock pursuant to the Series B Reclassification. The proceeds
from this transaction were used to redeem the Series A Preferred Stock and
Contingent Warrants ($2,115,000), to repay the Metromedia Loan and accrued
interest thereon ($4,058,126), to repay indebtedness to US ONE ($1,370,000), to
repay indebtedness to Sterling Capital LLC ("Sterling") ($555,000), and the
balance for working capital. Upon repayment of the Metromedia Loan, the
Repurchased Shares were released from escrow and delivered to the Company.

<PAGE>
METROMEDIA LEASE. In March 1997, the Company entered into an agreement to
lease approximately 5,300 square feet of office space in Manhattan from an
affiliate of Metromedia. The lease commenced on April 1, 1997. Aggregate monthly
rent payments are approximately $127,800 for the one year term of the lease. In
June 1997, the Company entered into another agreement with the same affiliate of
Metromedia to lease approximately 1,146 additional square feet of office space
in the same building. The lease commences on June 20, 1997. Aggregate monthly
rent payments are approximately $27,504 for the one year term of the lease. The
Company believes that the terms of the leases are fair to the Company and
comparable to those which have been obtained in arm's-length negotiations with
unaffiliated third parties.

TRADEMARK LICENSE AGREEMENT. MFN is a party to a license agreement with
Metromedia (the "Metromedia License Agreement"), pursuant to which Metromedia
has granted a non-exclusive, non-transferable, non-assignable right and license,
without the right to grant sublicenses, to use the trade name, trademark and
corporate name "Metromedia" in the United States and worldwide, royalty-free for
a term of 10 years. The Metromedia License Agreement can be terminated by
Metromedia upon one month's prior written notice in the event that (i)
Metromedia or its affiliates own less than 20% of the Common Stock; (ii) a
Change in Control of MFN (as defined below) occurs; or (iii) any of the stock or
all or substantially all of the assets of any of the subsidiaries of MFN are
sold or transferred, in which case, the Metromedia License Agreement shall
terminate with respect to such subsidiary. A Change in Control of MFN is defined
as (a) a transaction in which a person or "group" (within the meaning of Section
13(d)(3) of the Exchange Act) not in existence at the time of the execution of
the Metromedia License Agreement becomes the beneficial owner of stock entitling
such person or group to exercise 50% or more of the combined voting power of all
classes of stock of MFN; (b) a change in the composition of MFN's Board of
Directors whereby a majority of the members thereof are not directors serving on
the Board at the time of the Metromedia License Agreement or any person
succeeding such director who was recommended or elected by such directors; (c) a
reorganization, merger or consolidation where following consummation thereof,
Metromedia would hold less than 20% of the combined voting power of all classes
of MFN stock; (d) a sale or other disposition of all or substantially all of the
assets of MFN; or (e) any transaction the result of which would be that the
Common Stock would not be required to be registered under the Exchange Act and
the holders of Common Stock would not receive common stock of the survivor to
the transaction which is required to be registered under the Exchange Act.

In addition, Metromedia has reserved the right to terminate the Metromedia
License Agreement in its entirety immediately upon written notice to MFN if, in
Metromedia's sole judgment, MFN's continued use of "Metromedia" as a trade name
would jeopardize or be detrimental to the good will and reputation of
Metromedia.

Pursuant to the Metromedia License Agreement, MFN has agreed to indemnify
and hold harmless Metromedia against any and all losses, claims, suits, actions,
proceedings, investigations, judgments, deficiencies, damages, settlements,
liabilities and reasonable legal expenses (and other expenses related thereto)
arising in connection with the Metromedia License Agreement.

TRANSACTIONS ENTERED INTO IN CONNECTION WITH THE OFFERINGS

RECLASSIFICATIONS. In connection with the Offerings, the Company intends to
effect the Reclassifications. Pursuant to the Series B Reclassification, each
share of Series B Preferred Stock will be converted into and exchanged for 1,000
shares of Class B Common Stock. In connection with this transaction, the holders
of the Series B Preferred Stock have entered into an Exchange Agreement with the
Company which sets forth the mechanics of the exchange and certain of the rights
such holders will have going forward. Pursuant to the Common Stock
Reclassification, the Old Common Stock will be reclassified as Class A Common
Stock, with all of the rights and preferences currently found in the Common
Stock. See "Description of Capital Stock--Common Stock" for a description of the
relative rights of holders of Class A Common Stock and Class B Common Stock.

The following summary of certain provisions of the Common Stock and
Preferred Stock, outstanding warrants and related registration rights does not
purport to be complete and is subject to, and qualified in its entirety by, the
provisions of the Company's Amended and Restated Certificate of Incorporation
and Bylaws, copies of which have been filed as exhibits to the Registration
Statement of which this Prospectus is a part.

COMMON STOCK

The shares of Class A Common Stock and Class B Common Stock are identical in
all respects, except for voting rights and certain conversion rights and
transfer restrictions in respect of the shares of the Class B Common Stock. The
number of authorized shares of any class or classes of capital stock of the
Company may be increased or decreased (but not below the number of shares
thereof then outstanding) by the affirmative vote of the holders of a majority
of the voting power of the Common Stock of the Company entitled to vote
generally in the election of directors irrespective of the provisions of Section
242(b)(2) of the General Corporation Law of the State of Delaware (the "Delaware
Law") or any corresponding provisions hereinafter enacted.

VOTING RIGHTS. The holders of Class A Common Stock are entitled to one vote
per share. Holders of Class B Common Stock are entitled to ten votes per share.
Holders of all classes of Common Stock entitled to vote will vote together as a
single class on all matters presented to the stockholders for their vote or
approval except for the election and the removal of directors as described below
and as otherwise required by applicable law. In addition, with respect to the
election of directors, the Company's Amended and Restated Certificate of
Incorporation provides that holders of Class B Common Stock will vote as a
separate class to elect 75% of the members of the Company's Board.

Directors may be removed, with or without cause, only by the holders of the
class of Common Stock or series of Preferred Stock that, as of the date such
removal is effected, would be entitled to elect such director at the next annual
meeting of stockholders. Vacancies in a directorship may be filled only by (a)
the remaining directors elected by holders of each class of Common Stock or
series of Preferred Stock that (x) elected such director and (y) as of the date
such vacancy is filled, would be entitled to elect such director at the next
annual meeting of the stockholders or (b) if there are no such remaining
directors, then by the vote of the holders of the class or classes of Common
Stock or series of Preferred Stock, that, as of the date such vacancy is filled,
would be entitled to elect such director at the next annual meeting of
stockholders, voting as a separate class at a meeting, special or otherwise, of
the holders of Common Stock of such class or series of Preferred Stock.

DIVIDENDS. Holders of Class A Common Stock and the Class B Common Stock are
entitled to receive dividends at the same rate if, as and when such dividends
are declared by the Board out of assets legally available therefor after payment
of dividends required to be paid on shares of Preferred Stock, if any. The
Company may not make any dividend or distribution to any holder of any class of

55
<PAGE>
Common Stock unless simultaneously with such dividend or distribution the Common
Stock regardless of class, in the case of a dividend or other distribution
payable in shares of a class of Common Stock, including distributions pursuant
to Stock splits or divisions of Common Stock, only shares of Class A Common
Stock may be distributed with respect to Class A Common Stock and only shares of
Class B Common Stock may be distributed with respect to Class B Common Stock.
Whenever a dividend or distribution, including distributions pursuant to stock
splits or divisions of the Common Stock, is payable in shares of a class of
Common Stock, the number of shares of each class of Common Stock payable per
share of such class of Common Stock shall be equal in number. In the case of
dividends or other distributions consisting of other voting securities of the
Company or of voting securities of any corporation which is a wholly-owned
subsidiary of the Company, the Company shall declare and pay such dividends in
two separate classes of such voting securities, identical in all respects except
that (i) the voting rights of each such security issued to the holders of Class
A Common Stock shall be one-tenth of the voting rights of each such security
issued to holders of Class B Common Stock, (ii) such security issued to holders
of Class B Common Stock shall convert into the security issued to the holders of
Class A Common Stock upon the same terms and conditions applicable to the
conversion of Class B Common Stock into Class A Common Stock and shall have the
same restrictions on transfer and ownership applicable to the transfer and
ownership of the Class B Common Stock, and (iii) with respect only to dividends
or other distributions of voting securities of any corporation which is a wholly
owned subsidiary of the Company, the respective voting rights of each such
security issued to holders of the Class A Common Stock and Class B Common Stock
with respect to election of directors shall otherwise be as comparable as is
practicable to those of the Class A Common Stock and Class B Common Stock. In
the case of dividends or other distributions consisting of securities
convertible into, or exchangeable for, voting securities of the Company or of
voting securities of any corporation which is a wholly owned subsidiary of the
Company, the Company shall provide that such convertible or exchangeable
securities and the underlying securities be identical in all respects
(including, without limitation, the conversion or exchange rate) except that the
underlying securities may have the same differences as they would have if the
Company issued voting securities of the Company or of a wholly owned subsidiary
rather than issuing securities convertible into, or exchangeable for, such
securities. The Company does not anticipate paying cash dividends in the
foreseeable future. See "Dividend Policy."

RESTRICTIONS ON ADDITIONAL ISSUANCES AND TRANSFER. The Company may not
issue or sell any shares of Class B Common Stock or any securities (including,
without limitation, any rights, options, warrants or other securities)
convertible into, or exchangeable or exercisable for, shares of Class B Common
Stock to any person or entity other than to Metromedia, Messrs. Kluge and
Subotnick, their affiliates, relatives and certain other entities (the
"Permitted Holders"). Additionally, shares of Class B Common Stock may not be
transferred, whether by sale, assignment, gift, bequest, appointment or
otherwise, to a person other than to a Permitted Holder. Notwithstanding the
foregoing (i) any Permitted Holder may pledge his, her or its shares of Class B
Common Stock to a financial institution pursuant to a bona fide pledge of such
shares as collateral security for indebtedness due to the pledgee provided that
such shares remain subject to the transfer restrictions and that, in the event
of foreclosure or other similar action by the pledgee, such pledged shares of
Class B Common Stock may only be transferred to a Permitted Holder or converted
into shares of Class A Common Stock, as the pledgee may elect and (ii) the
foregoing transfer restrictions shall not apply in the case of a merger,
consolidation or business combination of the Company with or into another
corporation in which all of the outstanding shares of Common Stock and Preferred
Stock of the Company regardless of class are purchased by the acquiror.

CONVERSION. Class A Common Stock has no conversion rights. Shares of Class
B Common Stock are convertible into Class A Common Stock, in whole or in part,
at any time and from time to time at the option of the holder, on the basis of
one share of Class A Common Stock for each share of Class B Common Stock
converted. Additionally, at such time as a person ceases to be a (i) Permitted
Holder, any share of Class B Common Stock held by such person at such time shall
convert into a share of Class A Common Stock. The Company covenants that (i) it
will at all times reserve and keep available out of its

56
<PAGE>
authorized but unissued shares of Class A Common Stock, such number of shares of
Class A Common Stock issuable upon the conversion of all outstanding shares of
Class B Common Stock, (ii) it will cause any shares of Class A Common Stock
issuable upon conversion of a share of Class B Common Stock that require
registration with or approval of any governmental authority under federal or
state law before such shares may be issued upon conversion to be so registered
or approved and (iii) it will use its best efforts to list the shares of Class A
Common Stock required to be delivered upon conversion prior to such delivery
upon such national securities exchange upon which the outstanding Class A Common
Stock is listed at the time of such delivery.

RECLASSIFICATION AND MERGER. In the event of a reclassification or other
similar transaction as a result of which the shares of Class A Common Stock are
converted into another security, then a holder of Class B Common Stock will be
entitled to receive upon conversion the amount of such other security that the
holder would have received if the conversion occurred immediately prior to the
record date of such reclassification or other similar transaction. No
adjustments in respect of dividends will be made upon the conversion of any
share of Class B Common Stock; except if a share is converted subsequent to the
record date for the payment of a dividend or other distribution on shares of
Class B Common Stock but prior to such payment, then the registered holder of
such share at the close of business on such record date will be entitled to
receive the dividend or other distribution payable on such date regardless of
the conversion thereof or the Company's default in payment of the dividend due
on such date.

In the event the Company enters into any consolidation, merger, combination
or other transaction in which shares of Common Stock are exchanged for or
changed into other stock or securities, cash and/ or any other property, then,
and in such event, the shares of each class of Common Stock will be exchanged
for or changed into either (1) the same amount of stock, securities, cash and/or
any other property, as the case may be, into which or for which each share of
any other class of Common Stock is exchanged for or changed into shares of
capital stock, such shares so exchanged for or changed into may differ to the
extent and only to the extent that the Class A Common Stock and the Class B
Common Stock differ as provided in the Company's Amended and Restated
Certificate of Incorporation or (2) if holders of each class of Common Stock are
to receive different distributions of stock, securities, cash and/or any other
property, an amount of Stock, securities, cash and/or property per share having
a value, as determined by an independent investment banking firm of national
reputation selected by the Board of Directors, equal to the value per share into
which or for which each share of any other class of Common Stock is exchanged or
changed.

LIQUIDATION. In the event of a liquidation of the Company, after payment of
the debts and other liabilities of the Company and after making provision for
the holders of Preferred Stock, if any, the remaining assets of the Company will
be distributable ratably among the holders of the Class A Common Stock and Class
B Common Stock treated as a single class.

OTHER PROVISIONS. Except as described below, the holders of the Class A
Common Stock and Class B Common Stock are not entitled to preemptive rights.
None of the Class A Common Stock or Class B Common Stock may be subdivided or
combined in any manner unless the other classes are subdivided or combined in
the same proportion. The Company may not make any offering of options, rights or
warrants to subscribe for shares of Class B Common Stock. If the Company makes
an offering of options, rights or warrants to subscribe for shares of any other
class or classes of capital stock (other than Class B Common Stock) to all
holders of a class of Common Stock, then the Company is required to
simultaneously make an identical offering to all holders of the other classes of
Common Stock other than to any class the holders of which, voting as a separate
class, agrees that such offering need not be made to such class. All such
options, rights or warrants offerings shall offer the respective holders of
Class A Common Stock and Class B Common Stock the right to subscribe at the same
rate per share. All outstanding shares of Common Stock are, and all shares of
Common Stock offered hereby when issued will be, upon payment therefor, validly
issued, fully paid and nonassessable.

57
<PAGE>
Delaware law does not require stockholder approval for any issuance of
authorized shares of Common Stock. Such authorized and unissued shares may be
used for a variety of corporate purposes, including future public offerings to
raise additional capital or to facilitate corporate acquisitions. One of the
effects of the existence of unissued and unreserved Common Stock may be to
enable the Board to issue shares to persons friendly to current management,
which issuance could render more difficult or discourage an attempt to obtain
control of the Company by means of a merger, tender offer, proxy consent or
otherwise, and thereby protect the continuity of the Company's current
management and possibly deprive the stockholders of opportunities to sell their
shares of Common Stock at prices higher than prevailing market prices.

At present there is no established trading market for the Class A Common
Stock.

Application to list the shares of the Class A Common Stock has been made to
the Nasdaq National Market under the proposed symbol "MFBR".

PREFERRED STOCK

The Board has the authority, without any further action by the stockholders
of the Company, to issue from time to time shares of Preferred Stock in one or
more series and to fix the designations, preferences, rights, qualifications,
limitations and restrictions thereof, including voting rights, dividend rights,
dividend rates, conversion rights, terms of redemption, redemption prices,
liquidation preferences and the number of shares constituting any series. The
issuance of Preferred Stock with voting rights could have an adverse effect on
the voting power of holders of Common Stock by increasing the number of
outstanding shares having voting rights. In addition, if the Board authorizes
Preferred Stock with conversion rights, the number of shares of Common Stock
outstanding could potentially be increased up to the authorized amount. The
issuance of Preferred Stock could decrease the amount of earnings and assets
available for distribution to holders of Common Stock. Any such issuance could
also have the effect of delaying, deterring or preventing a change in control of
the Company and may adversely affect the rights of holders of Common Stock. The
Board does not presently intend to issue any additional shares of Preferred
Stock.

DELAWARE LAW AND CERTAIN CHARTER AND BY-LAW PROVISIONS

As a Delaware corporation, the Company is subject to the DGCL, including
Section 203. Section 203 of the DGCL prohibits certain transactions between a
Delaware corporation and an "interested stockholder," which is defined as a
person who, together with any affiliates or associates of such person,
beneficially owns, directly or indirectly, 15% or more of the outstanding voting
shares of a Delaware corporation. This provision prohibits certain business
combinations (defined broadly to include mergers, consolidations, sales or other
dispositions of assets having an aggregate value in excess of 10% of the
consolidated assets of the corporation, and certain transactions that would
increase the interested stockholder's proportionate share ownership in the
corporation) between an interested stockholder and a corporation for a period of
three years after the date the interested stockholder becomes an interested
stockholder, unless (i) prior to the date the interested stockholder becomes an
interested stockholder, the business combination or the transaction by which the
stockholder becomes an interested stockholder is approved by the corporation's
board of directors, (ii) upon consummation of the transaction which resulted in
the stockholder becoming an interested stockholder, such stockholder held at
least 85% of the voting stock of the corporation outstanding at the time the
transaction commenced (other than stock held by directors who are also officers
or by certain employee stock plans) or (iii) the business combination is
approved by a majority of the board of directors, and at an annual or special
meeting of stockholders, and not by written consent, by the affirmative vote of
66 2/3% of the outstanding voting stock that is not owned by the interested
stockholder. Mr. Garofalo and Metromedia are interested stockholders under the
DGCL. However since their acquisition of the Company's securities was approved
in

58
<PAGE>
advance by the Company's Board of Directors, they would not be prohibited from
engaging in a business combination with the Company.

ADVANCE NOTICE REQUIREMENTS FOR STOCKHOLDER PROPOSALS AND DIRECTOR
NOMINATIONS. The By-laws provide that stockholders seeking to bring business
before an annual meeting of stockholders, or to nominate candidates for election
as directors at an annual or special meeting of stockholders, must provide
timely notice thereof in writing. To be timely, a stockholder's notice must be
delivered to or mailed and received at the principal executive offices of the
Company not less than 70 days nor more than 90 days prior to the meeting;
provided, however, that in the event that the date of the annual meeting is
advanced by more than 20 days or delayed by more than 70 days from such
anniversary date, notice by the stockholder to be timely must be received no
earlier than the close of business on the ninetieth day prior to such annual
meeting and not later than the close of business on the later of the seventieth
day prior to such annual meeting or the tenth day following the day on which
public announcement of the date of such meeting is first made. The By-laws also
specify certain requirements for a stockholder's notice to be in proper written
form. These provisions may preclude some stockholders from bringing matters
before the stockholders at an annual or special meeting or from making
nominations for directors at an annual or special meeting.

The Company's Amended and Restated Certificate of Incorporation provides
that to the fullest extent permitted by the DGCL, no director of the Company
shall be liable to the Company or its stockholders for monetary damages for
breach of fiduciary duty as a director. Under current Delaware law, liability of
a director may not be limited (i) for any breach of the director's duty of
loyalty to the Company or its stockholders, (ii) for acts or omissions not in
good faith or that involve intentional misconduct or a knowing violation of law,
(iii) in respect of certain unlawful dividend payments or stock redemptions or
repurchases and (iv) for any transaction from which the director derives an
improper personal benefit. The effect of the provision of the Charter is to
eliminate the rights of the Company and its stockholders (through stockholders'
derivative suits on behalf of the Company) to recover monetary damages against a
director for breach of the fiduciary duty of care as a director (including
breaches resulting from negligent or grossly negligent behavior) except in the
situations described in clauses (i) through (iv) above. This provision does not
limit or eliminate the rights of the Company or any stockholder to seek
nonmonetary relief such as an injunction or rescission in the event of a breach
of a director's duty of care. In addition, the Charter provides that the Company
shall indemnify its directors, officers, employees and agents to the extent not
prohibited by Delaware law.

In addition, prior to the completion of the Offerings, the Company intends
to enter into agreements (the "Indemnification Agreements") with each of the
directors of the Company pursuant to which the Company will agree to indemnify
each such director against claims, liabilities, damages, expenses, losses,
costs, penalties or amounts paid in settlement (collectively, "Losses") incurred
by such director and arising out of his capacity as a director, executive
officer, employee and/or agent of the Company to the maximum extent permitted by
applicable law. In addition, such director or officer shall be entitled to an
advance of expenses to the maximum extent authorized or permitted by law to meet
the obligations indemnified against. The Indemnification Agreements will also
obligate the Company to purchase and maintain insurance for the benefit and on
behalf of its directors insuring against all liabilities that may be incurred by
such director in or arising out of his capacity as a director, officer, employee
and/or agent of the Company.

To the extent that the Board or the stockholders of the Company may in the
future wish to limit or repeal the ability of the Company to indemnify
directors, such repeal or limitation may not be effective as to directors who
are currently parties to the Indemnification Agreements, because their rights to
full protection will be contractually assured by the Indemnification Agreements.
It is anticipated that similar contracts may be entered into, from time to time,
with future directors and with executive officers of the Company.

WARRANTS

In February, 1997, the Company issued to a customer (in replacement for an
existing warrant) a warrant to purchase 900,000 shares of Class A Common Stock
at an exercise price of $2.46 per share. The new warrant expires on February 13,
2000.

On June 14, 1996, the Company issued 75,000 Class A Common Stock purchase
warrants to two investors. The warrants are exercisable at $1.333 per share for
a period of 3 years (the "Exercise Period"), provided that in the event of an
initial public offering of the Company's Common Stock during the Exercise
Period, the exercise price will be reduced to the lesser of $1.333 or one half
of the initial public offering price per share.

On September 24, 1996, the Company issued an aggregate of 186,000 Common
Stock purchase warrants to various bridge lenders (the "Bridge Warrants"). The
exercise price of the warrants is the lesser of (i) $3.00 per share; (ii) the
price at which the Company issues its securities in the future if less than
$3.00; or (iii) one half of the price at which the Class A Common Stock of the
Company is offered in an initial public offering. The exercise price is subject
to further reduction to a price such that the difference between the exercise
price and the market price of a share would yield an aggregate gross profit upon
exercise of all of the warrants equal to at least $550,000. The warrants are
exercisable on the later of September 24, 1999 or twelve months after the
Company has completed an initial public offering and the shares issuable
pursuant to the exercise of the warrants have been covered by an effective
registration statement which has remained in effect for 90 days. The warrants
are subject to provisions for the adjustment of the exercise price and the
aggregate number of shares issuable upon exercise of the warrants under certain
circumstances, including stock dividends, stock splits and reclassifications.

In October 1995, concurrent with the issuance of notes in a private
offering, warrants were issued by the Company to certain noteholders which are
exercisable at a rate of 30,000 shares of common stock per $100,000 of note
principal. Such warrants, entitling the holders to purchase an aggregate of
257,400 shares, are exercisable at a price equal to 50% of the per share price
of an initial public offering of common stock over a three-year period beginning
on the effective date of such initial public offering. The warrants are subject
to provisions for the adjustment of the exercise price and the aggregate number
of shares issuable upon exercise of the warrants under certain circumstances,
including stock dividends, stock splits and reclassifications.

In December 1996, the Company offered certain private placement noteholders
warrants to purchase 211,200 shares of its Class A Common Stock exercisable at
one half of the price for which shares are sold in an initial public offering
for a period of three years following such offering in exchange for the
extension of the due dates of the notes. All of the noteholders accepted this
offer. The warrants are subject to provisions for the adjustment of the exercise
price and the aggregate number of shares issuable upon exercise of the warrants
under certain circumstances, including stock dividends, stock splits and
reclassifications.

In March 1997 the Company issued warrants to private placement noteholders
to purchase 113,772 shares of Class A Common Stock exercisable at one half of
the price for which shares are sold in an initial public offering for a period
of three years following such offering in exchange for the extension of the due
dates of the notes. The warrants are subject to provisions for the adjustment of
the exercise price and the aggregate number of shares issuable upon exercise of
the warrants under certain circumstances, including stock dividends, stock
splits and reclassifications.

On December 13, 1996, the Company issued and sold to an investor warrants to
purchase 225,000 shares of Class A Common Stock at an exercise price of $2.50
per share (the "Investor Warrants") and a contingent stock subscription warrant
to purchase a number of shares of Class A Common Stock (such number to be
determined based upon certain future events) at an exercise price of $0.01 per
share (the "Contingent Warrants"). On April 30, 1997, the Contingent Warrants,
along with a series of preferred

60
<PAGE>
stock the investor had acquired, were redeemed at an aggregate redemption price
of $2,115,000. In connection therewith, the number of Investor Warrants was
increased from 225,000 to 450,000. The Investor Warrants are exercisable on or
prior to December 31, 2001. The Investor Warrants contain provisions for the
adjustment of the exercise price and the aggregate number of shares issuable
upon the exercise of a warrant under certain circumstances including the
issuance of Class A Common Stock, options to purchase Class A Common Stock or
securities convertible into Class A Common Stock at a price less than the
exercise price, stock dividends, stock splits, combinations, capital
reorganizations and reclassifications. In addition, at any time within one year
of a change of control in the Company or after the second anniversary of the
grant of the Investor Warrants, the holders of Investor Warrants have the right
to require the Company to repurchase all of the shares issued pursuant to the
warrants or represented by the warrants.

Another of the Company's customers, subject to the satisfaction of certain
conditions set forth in an agreement with the Company, may acquire warrants to
purchase a minimum of 150,000 and, subject to the approval of the Company, a
maximum of 900,000 Class A Common Stock purchase warrants exercisable at $0.01
per share (the "Customer Warrants"). The purchase price for the warrants shall
be either (i) $.7456 per warrant, or (ii) in the event that the Company sells
Class A Common Stock in a private placement for an aggregate purchase price of
$7,500,000 or more, the sales price per warrant shall be the same as the price
per share of Class A Common Stock in such placement less $0.01; PROVIDED THAT,
in no event shall the aggregate purchase price exceed $1.25 million. The
warrants are exercisable on or prior to March 20, 2009. The warrants have
provisions for adjustment of the number of shares issuable upon exercise of the
warrants under certain circumstances including stock dividends, stock splits,
combinations, issuances of additional shares of Class A Common Stock at a price
less than the current market value of the Class A Common Stock, and issuances of
warrants, options, convertible securities or indebtedness or other rights,
exercisable for or convertible into Class A Common Stock at an exercise price
less than the current market value of the Class A Common Stock. In addition, at
any time on or after December 21, 2001 but prior to the earlier of March 20,
2009 or the consummation of public offering meeting certain criteria, the
warrant holder has the right to require the Company to purchase all of the
shares issued pursuant to the exercise of the warrants owned by such holder at a
price per share equal to the current market value per share of Class A Common
Stock and all of the warrants at a price equal to the current market value per
share of Class A Common Stock multiplied by the number of shares for which such
warrant is exercisable less the aggregate exercise price of such shares.

REGISTRATION RIGHTS

After the Company's initial public offering, each time that the Company
proposes to register any of its securities (other than on a registration
statement on Form S-8 or Form S-4) under the Securities Act, holders of the
Customer Warrants have the right to have their shares of Class A Common Stock of
the Company, whether owned as of the date of the grant of the warrant or issued
pursuant to the exercise of the warrant (the "Registrable Shares"), included in
such registration. If the managing underwriter advises the Company in writing
that the number of shares requested to be included in such registration exceeds
the number of shares which can be sold in such offering, the Company will be
obligated to include in such registration only (i) first, any and all shares of
Class A Common Stock for sale by the Company, and (ii) second, pro rata among
the Registrable Shares and any other shares of Class A Common Stock requested to
be included in the registration pursuant to any other registration rights. The
Company is required to use all reasonable efforts to effect the registration and
the sale of the Registrable Shares.

Pursuant to a letter agreement dated February 11, 1996 between Mr. Sahagen
and the Company, Mr. Sahagen was granted the same "piggyback" registration
rights as those granted to the holders of the Customer Warrants with respect to
shares of Class A Common Stock owned by him.

61
<PAGE>
For five years after the issuance of the Bridge Warrants, at any time the
Company proposes to file a registration statement for the public sale of
securities (other than in connection with a merger or pursuant to Form S-4, Form
S-8 or a comparable registration statement), holders of these warrants have the
right to include the shares underlying the warrants registered under such
registration statement. If the managing underwriter advises the Company in
writing that the number of shares requested to be included in such registration
exceeds the number of shares which can be sold in such offering, the Company
will be obligated to include in such registration only (i) first, any and all
shares of Class A Common Stock for sale by the Company, and (ii) second, pro
rata among the shares underlying the warrants and any other shares of Class A
Common Stock requested to be included in the registration pursuant to any other
registration rights.

On March 20, 1996, an individual entered into a consulting and stock sale
agreement with the Company under which such individual received 360,000 shares
of Class A Common Stock and certain registration rights. After the Company's
initial public offering, at any time the Company proposes to register its
securities (other than pursuant to a Form S-4 or Form S-8 or in connection with
a merger), such individual has the right to include his shares in such
registration. If the managing underwriter in such offering advises the Company
that it declines to include a portion or all of the shares requested by such
individual to be included in the registration statement, then such portion or
all of such shares shall be excluded from the registration statement, with a
portion of the excluded shares allocated to such individual in proportion to the
respective numbers of shares requested to be registered by such individual.

On April 15, 1996, VCNY entered into a stock purchase agreement with the
Company for the purchase of 3,000,000 shares of Class A Common Stock. Under that
agreement, certain piggyback rights were granted to VCNY. In the event the
Company proposes to register any of its securities (other than in connection
with an initial public offering, a merger or pursuant to Form S-4 or Form S-8),
the Company is required, at VCNY's request, to include the shares sold to VCNY
in such registration. If the managing underwriter in such offering advises the
Company that it declines to include a portion or all of the shares requested by
VCNY to be included in the registration statement, then such portion or all of
such shares shall be excluded from the registration statement, with the excluded
shares being allocated among all shareholders requesting registration in
proportion to the respective numbers of shares requested to be registered by
each such shareholder. On October 9, 1996, VCNY and MFN entered into a
settlement agreement which provided for the termination of Mr. Vento's
employment with the Company. The agreement also provided for a general release
of all claims that VCNY or Mr. Vento had against the Company. However, whether
the VCNY's registration rights under the stock purchase agreement survive the
settlement agreement is unclear.

Pursuant to employment agreements and stock option agreements with the
Company, certain officers of the Company have rights with respect to the
registration of the shares underlying their stock options. Stephen A. Garofalo
was granted options to purchase 750,000 shares of Class A Common Stock, and
Howard Finkelstein was granted 3,000,000 shares of Class A Common Stock. John
Mahon and Jim Urbelis were both granted options to purchase 270,000 shares of
Class A Common Stock, and Vincent Galluccio has been granted options to purchase
390,000 shares of Class A Common Stock. Upon the consummation of an initial
public offering, the Company is required to register the shares underlying the
stock options of Mr. Garofalo on Form S-8 and Mr. Finkelstein's shares. At any
time the Company proposes to file a registration statement on Form S-8, and if
permissible under such form, the Company is required to include on such
statement the shares underlying the stock options of Messrs. Mahon, Urbelis and
Galluccio.

Under the Metromedia Agreement, as amended, Metromedia, Stuart Subotnick,
Arnold Wadler and Silvia Kessel (the "Buyers") and Stephen A. Garofalo, were
granted certain demand and piggyback registration rights. At any time, Mr.
Garofalo or the holders of a majority of the Class B Common Stock owned by the
Buyers or issuable upon conversion of the Class B Common Stock ("Majority
Holders")

62
<PAGE>
may demand that the Company register their shares of Class A Common Stock
(assuming holders of Class B Common Stock have converted their shares of Class B
Common Stock into shares of Class A Common Stock), and upon such demand, the
Company is required to use its best efforts to effect such registration. With
certain exceptions, unless Garofalo or the Majority Holders consent to such
inclusion, no such registration may include any other securities. For each of
Garofalo, and the Majority Holders, the Company is not required to effect (i)
more than three such registrations in the aggregate; (ii) more than two such
registrations within any six month period; (iii) any such registration within
six months after the effectiveness of a registration by the Company offering its
Class A Common Stock (other than a registration on Form S-8 with respect to an
employee benefit plan), unless the Company has completed the sale of at least
80% of the offering pursuant to such registration; or (iv) any such registration
valued at less than $5,000,000 based upon the then current market price or fair
market value as estimated by the Company's underwriters.

Each time the Company proposes to file a registration statement to register
its securities (except for registration on Form S-4 or Form S-8), the Company
will use its best efforts to effect the registration of shares requested to be
registered by Mr. Garofalo or the Buyers. In the case of any such piggyback
registration in connection with a demand registration initiated by Metromedia,
Mr. Subotnick, Ms. Kessel, or Mr. Wadler, the amount of shares to be included in
such piggyback registration may not, without the prior written consent of the
person initiating the demand registration, exceed 10% of Mr. Garofalo's total
equity interest in the Company. In the case of a piggyback registration in
connection with a demand registration initiated by Mr. Garofalo or Mr.
Finkelstein, the amount of shares to be included in such piggyback registration
may not, without the prior written consent of the person initiating the demand
registration, exceed 10% of the Buyers' total equity interest in the Company. In
the case of any such piggyback registration in connection with an underwritten
primary registration on behalf of the Company, if the Company's underwriters
advise the Company in writing that the number of shares to be included in such
registration exceeds the number of shares which, in the estimation of such
underwriters, can be reasonably expected to be sold in such offering, then the
Company shall include in such registration (i) first, the Class A Common Stock
for sale by the Company and (ii) second, if additional shares of Class A Common
Stock can be included in such registration in the estimation of the Company's
underwriters, the shares requested by Mr. Garofalo or the Buyers, on a pro rata
basis with each other eligible person.

SHARES ELIGIBLE FOR FUTURE SALE

Prior to the Offerings, there has been no market for the shares of the Class
A Common Stock. Sales of a substantial amount of Class A Common Stock in the
public market, or the perception that such sales may occur, could adversely
affect the market price of the Class A Common Stock prevailing from time to time
in the public market and could impair the Company's ability to raise additional
capital through the sale of its equity securities in the future.

In general, under Rule 144 as currently in effect, if one year has elapsed
since the later of the date of acquisition of restricted securities from the
Company or any "affiliate" of the Company, as that term is defined under the
Securities Act, the holder is entitled to sell within any three-month period a
number of shares of Class A Common Stock that does not exceed the greater of 1%
of the then-outstanding shares of the Class A Common Stock or the average weekly
trading volume of shares of Class A Common Stock on all exchanges and reported
through the automated quotation system of a registered security association
during the four calendar weeks preceding the date on which notice of the sale is
filed with the Commission. Sales under Rule 144 are also subject to certain
restrictions on the manner of sales, notices, requirements and the availability
of current public information about the Company. If two years

63
<PAGE>
have elapsed since the date of acquisition of restricted shares from the Company
or from any "affiliate" of the Company, and the holder thereof is deemed not to
have been an affiliate of the Company at any time during the 90 days preceding a
sale, such person would be entitled to sell such Class A Common Stock in the
public market under Rule 144(k) without regard to the volume limitations, manner
of sale provisions, public information requirements or notice requirements.

Upon completion of the Offerings, the Company will have approximately
shares of Class A Common Stock outstanding ( if the Underwriters'
overallotment option is exercised in full), including shares of Class A
Common Stock sold in the Offerings ( if the Underwriters' overallotment
option is exercised in full) and "restricted" shares of Common Stock. Of
the restricted shares held by persons other than "affiliates" of the Company
within the meaning of Rule 144, shares of Class A Common Stock are
currently eligible for sale under Rule 144, as currently in effect, and an
additional shares of Class A Common Stock will be eligible for sale under
rule 144, as currently in effect, beginning in , 1998.

The shares of Class A Common Stock offered in the Offerings will be freely
tradeable without restriction or further registration under the Securities Act
by persons other than "affiliates" of the Company within the meaning of Rule
144. The holders of restricted shares generally will be entitled to sell these
shares in the public securities market without registration under the Securities
Act to the extent permitted by Rule 144 or any exemption under the Securities
Act.

The Company and each of its executive officers and directors and certain
other stockholders have entered into lock-up agreements with the Underwriters,
providing that, subject to certain exceptions, they will not, for a period of
180 days from the date of this Prospectus, offer, sell or contract to sell or
otherwise dispose, directly or indirectly, or announce an offering of, any
shares of Class A Common Stock or any securities convertible into, or
exchangeable for, shares of Class A Common Stock without prior written consent
of Salomon Brothers Inc, subject to certain exceptions. See "Underwriting."

Promptly after completion of the Offerings, the Company intends to file with
the Commission a Registration Statement on Form S-8, covering the shares of
Common Stock issuable upon exercise of certain officer's options and the shares
of Class A Common Stock underlying options granted under the 1997 Incentive
Stock Plan and the Plan. This registration statement will become effective
immediately upon filing with the Commission. As a result, the shares of Class A
Common Stock so registered and acquired pursuant to the 1997 Incentive Stock
Plan and the Plan will be available for sale by non-affiliates in the
public securities market without limitation and by affiliates, subject to the
volume limitations of Rule 144.

UNDERWRITING

Subject to the terms and conditions set forth in an underwriting agreement
among the Company and the U.S. Underwriters (the "U.S. Underwriting Agreement"),
the Company has agreed to sell to each of the U.S. Underwriters named below (the
"U.S. Underwriters"), and each of the U.S. Underwriters, for whom Salomon
Brothers Inc, Donaldson, Lufkin & Jenrette Securities Corporation and
are acting as the U.S. representatives (the "U.S. Representatives"),
has severally agreed to purchase from the Company the number of shares of Class
A Common Stock set forth opposite its name below.

</TABLE>

The Company has been advised by the U.S. Representatives that the several
U.S. Underwriters initially propose to offer such shares of Class A Common Stock
to the public at the public offering price set forth on the cover page of this
Prospectus and to certain dealers at such price less a concession not in excess
of $ per share of Class A Common Stock. The U.S. Underwriters may allow, and
such dealers may re-allow, a concession not in excess of $ per share of Class
A Common Stock to other dealers. After the Offerings, the public offering price
and such concessions may be changed.

The Company has granted to the U.S. Underwriters and the international
underwriters (the "International Underwriters" and, collectively with the U.S.
Underwriters, the "Underwriters") an option, exercisable during the 30-day
period after the date of this Prospectus, to purchase up to additional shares
of Class A Common Stock from the Company at the price to public less the
underwriting discount, solely to cover over-allotments. To the extent that the
U.S. Underwriters and the International Underwriters exercise such option, each
of the U.S. Underwriters and the International Underwriters, as the case may be,
will be committed, subject to certain conditions, to purchase a number of option
shares proportionate to such U.S. Underwriter's or International Underwriter's
initial commitment.

The Company has entered into an International Underwriting Agreement with
the International Underwriters named therein, for whom Salomon Brothers
International Limited, Donaldson, Lufkin & Jenrette Securities Corporation and
are acting as the representatives (the "International Representatives"
and, together with the U.S. Representatives, the "Representatives"), providing
for the concurrent offer and sale of shares of Class A Common Stock (in
addition to the shares covered by the over-allotment options described above)
outside the United States and Canada. Both the U.S. Underwriting Agreement and
the International Underwriting Agreement provide that the obligations of the
U.S. Underwriters and the International Underwriters are such that if any of the
shares of Class A Common Stock are purchased by the U.S. Underwriters pursuant
to the U.S. Underwriting Agreement, or by the International Underwriters
pursuant to the International Underwriting Agreement, all the shares of Class A
Common Stock agreed to be purchased by either the U.S. Underwriters or the
International

65
<PAGE>
Underwriters, as the case may be, pursuant to their respective agreements must
be so purchased. The price to public and underwriting discount per share of
Class A Common Stock for the U.S. Offering and the International Offering will
be identical. The closing of the International Offering is a condition to the
closing of the U.S. Offering and the closing of the U.S. Offering is a condition
to the closing of the International Offering.

Each U.S. Underwriter has severally agreed that, as part of the distribution
of the shares of Class A Common Stock offered by the U.S. Underwriters, (i)
it is not purchasing any shares of Class A Common Stock for the account of
anyone other than a United States or Canadian Person and (ii) it has not offered
or sold, and will not offer or sell, directly or indirectly, any shares of Class
A Common Stock or distribute this Prospectus to any person outside of the United
States or Canada or to anyone other than a United States or Canadian Person.
Each International Underwriter has severally agreed that, as part of the
distribution of the shares of Class A Common Stock offered by the
International Underwriters, (i) it is not purchasing any shares of Class A
Common Stock for the account of any United States or Canadian Person and (ii) it
has not offered or sold, and will not offer or sell, directly or indirectly, any
shares of Class A Common Stock or distribute any Prospectus relating to the
International Offering to any person in the United States or Canada or to any
United States or Canadian Person.

The foregoing limitations do not apply to stabilization transactions or to
certain other transactions specified in the Agreement Between U.S. Underwriters
and International Underwriters. "United States or Canadian Person" means any
person who is a national or resident of the United States or Canada, any
corporation, partnership or other entity created or organized in or under the
laws of the United States or Canada or of any political subdivision thereof, and
any estate or trust the income of which is subject to United States or Canadian
federal income taxation, regardless of the source of its income (other than the
foreign branch of any United States or Canadian Person), and includes any United
States or Canadian branch of a person other than a United States or Canadian
Person.

Pursuant to the Agreement Between U.S. Underwriters and International
Underwriters, sales may be made between the U.S. Underwriters and the
International Underwriters of such number of shares of Class A Common Stock as
may be mutually agreed. The price of any shares of Class A Common Stock so sold
shall be the public offering price, less an amount not greater than the
concession to securities dealers. To the extent that there are sales between the
U.S. Underwriters and the International Underwriters pursuant to the Agreement
Between U.S. Underwriters and International Underwriters, the number of shares
of Class A Common Stock initially available for sale by the U.S. Underwriters or
by the International Underwriters may be more or less than the amount specified
on the cover page of this Prospectus.

Any offer of the shares of Class A Common Stock in Canada will be made only
pursuant to an exemption from the registration and qualification requirements in
any jurisdiction in Canada in which such offer is made.

The U.S. Underwriting Agreement and the International Underwriting Agreement
provide that the Company will indemnify the U.S. Underwriters and the
International Underwriters against certain liabilities and expenses, including
liabilities under the Securities Act, or contribute to payments the U.S.
Underwriters and the International Underwriters may be required to make in
respect thereof.

The Company, and each of its directors and officers and certain other
stockholders have agreed not to offer, sell, contract to sell or otherwise
dispose of, directly or indirectly, or announce the offering of any shares of
Class A Common Stock, including any such shares beneficially or indirectly owned
or controlled by the Company, or any securities convertible into, or
exchangeable or exercisable for, shares of Class A Common Stock, for 180 days
from the date of this Prospectus, without the prior written consent of Salomon
Brothers Inc, except for (i) shares issued in connection with any employee
benefit or incentive plans of the Company existing on the date of this
Prospectus, (ii) shares issued in respect of obligations existing before the
date of this Prospectus and (iii) shares in connection with the Offerings.

66
<PAGE>
At the Company's request, the U.S. Underwriters have reserved up to
shares of Class A Common Stock (the "Directed Shares") for sale at the public
offering price to persons who are directors, officers or employees of, or
otherwise associated with, the Company and its affiliates and who have advised
the Company of their desire to purchase such shares of Class A Common Stock. The
number of shares of Class A Common Stock available for sale to the general
public will be reduced to the extent of sales of Directed Shares to any of the
persons for whom they have been reserved. Any shares of Class A Common Stock not
so purchased will be offered by the U.S. Underwriters on the same basis as all
other shares of Class A Common Stock offered hereby.

Certain persons engaged in the distribution of the shares of Class A Common
Stock may engage in stabilizing transactions, syndicate covering transactions
and penalty bids in accordance with Rule 104 under the Exchange Act. Stabilizing
transactions permit bids to purchase the underlying security so long as the
stabilizing bids do not exceed a specified maximum. Syndicate covering
transactions involve purchases of shares of Class A Common Stock in the open
market after the distributions has been completed in order to cover syndicate
short positions. Penalty bids permit an underwriter to reclaim a selling
concession from a syndicate member when the shares of Class A Common Stock
originally sold by such syndicate member are purchased in a syndicate covering
transaction to cover syndicate short positions. Underwriters and prospective
underwriters intend to engage in passive market making in accordance with Rule
103 under the Exchange Act, which, in general, permits entities which are Nasdaq
market makers to continue to maintain bids for the shares of Class A Common
Stock so long as certain price and daily quantity limits are observed. Such
stabilizing transactions, syndicate covering transactions, penalty bids and
passive market making may cause the price of the Class A Common Stock to be
higher than it would otherwise be in the absence of such transactions.

Prior to the Offerings, there has been no public market for the Class A
Common Stock. The initial public offering price was determined by negotiations
between the Company and the Representatives. Among the factors considered in
determining the initial public offering price were the information set forth in
this Prospectus and otherwise available to the Representatives, the history of
and future prospects for the industry in which the Company competes, the ability
of the Company's management, the general conditions of the securities market at
the time of the Offerings and the market prices of securities and certain
financial and operating information of companies engaged in activities similar
to those of the Company. There can be no assurance that the price at which the
shares of Class A Common Stock will sell in the public market after the
Offerings will not be lower than the price at which they are sold in the
Offerings by the Underwriters.

The U.S. Underwriters and the International Underwriters do not intend to
confirm sales to any accounts over which they exercise discretionary authority.

This Company has applied to have the Class A Common Stock quoted in the
Nasdaq National Market under the proposed symbol MFBR.

CERTAIN FEDERAL TAX CONSEQUENCES

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
"Non-United States Holder" and of the issuance of the Class A Common Stock by
the Company. A "Non-United States Holder" is a person or entity that, for U.S.
Federal income tax purposes, is (i) a non-resident alien individual, (ii) a
foreign corporation or partnership, (iii) an estate, other than an estate the
income of which is includible in gross income for United States Federal income
tax purposes regardless of its source, or (iv) a trust that is not subject
either to the primary supervision of a court within the United States or the
control of a United States fiduciary.

This discussion is based on the Code and administrative interpretations as
of the date hereof, all of which may be changed either retroactively or
prospectively. This discussion does not address all aspects of U.S. Federal
income and estate taxation that may be relevant to Non-United States Holders in
light of their particular circumstances and does not address any tax
consequences arising under the laws of any state, local or foreign taxing
jurisdiction.

Prospective holders should consult their tax advisors with respect to the
United States Federal, state, local and non-United States income and other tax
consequences to them of holding and disposing of Class A Common Stock.

CONSEQUENCES TO NON-UNITED STATES HOLDERS OF COMMON STOCK

DIVIDENDS

Subject to the discussion below, dividends paid to a Non-United States
Holder of Class A Common Stock generally will be subject to withholding tax at a
30% rate or such lower rate as may be specified by an applicable income tax
treaty unless the dividend is effectively connected with the conduct of a trade
or business within the United States, or, if an income tax treaty applies, is
attributable to a United States permanent establishment of the Non-United States
Holder and, in either case, the Non-United States Holder provides the payor with
proper documentation (Form 4224), in which event the dividend will be taxable
under the rules discussed below. In order to claim the benefit of an applicable
tax treaty rate, a Non-United States Holder may have to file with the Company or
its dividend paying agent an exemption or reduced treaty rate certificate or
letter in accordance with the terms of such treaty.

Under current United States Treasury regulations, for purposes of
determining whether tax is to be withheld at a 30% rate or at a reduced rate as
specified by an income tax treaty, the Company ordinarily will presume that
dividends paid to a stockholder at an address in a foreign country are paid to a
resident of such country absent knowledge that such presumption is not
warranted. However, under proposed United States Treasury regulations which have
not yet been put into effect, additional certification requirements would apply
after December 1, 1997. See "--Information Reporting Requirements and Backup
Withholding Tax."

In the case of dividends that are effectively connected with the Non-United
States Holder's conduct of a trade or business within the United States or, if
an income tax treaty applies, are attributable to a United States permanent
establishment of the Non-United States Holder, the Non-United States Holder will
generally be subject to regular U.S. income tax in the same manner as if the
Non-United States Holder were a United States resident. A Non-United States
corporation receiving effectively connected dividends also may be subject to an
additional "branch profits tax" which is imposed, under certain circumstances,
at a rate of 30% (or such lower rate as may be specified by an applicable
treaty) of the Non-United States corporation's "effectively connected earnings
and profits," subject to certain adjustments.

68
<PAGE>
GAIN ON DISPOSITION OF CLASS A COMMON STOCK

A Non-United States Holder generally will not be subject to U.S. Federal
income tax with respect to gain realized on a sale or other disposition of Class
A Common Stock unless (i) the gain is effectively connected with a trade or
business of such Non-United States Holder in the U.S., (ii) in the case of
certain Non-United States Holders who are non-resident alien individuals and
hold the Common Stock as a capital asset, such individuals are present in the
U.S. for 183 or more days in the taxable year of the disposition and either (a)
such individuals have a "tax home" (as defined for United States Federal income
tax purposes) in the U.S., or (b) the gain is attributable to an office or other
fixed place of business maintained by such individuals in the U.S., (iii) the
Non-United States Holder is subject to tax, pursuant to the provisions of U.S.
tax law applicable to certain U.S. expatriates, or (iv) the Company is or has
been a "United States real property holding corporation" within the meaning of
Section 897(c)(2) of the Code at any time within the shorter of the five-year
period preceding such disposition or such Non-United States holding period.

The Company believes that it is not currently, but may become, a United
States real property holding corporation. If the Company were to become a United
States real property holding corporation, any gain recognized by a Non-United
States Holder would be subject to United States Federal income tax if the Common
Stock were regularly traded on an established securities market for tax purposes
and the Non-United States Holder held, directly or indirectly, at any time
within the five-year period preceding such disposition more than 5% of the
outstanding Class A Common Stock.

INFORMATION REPORTING REQUIREMENTS AND BACKUP WITHHOLDING TAX

Under United States Treasury regulations, the Company must report annually
to the Internal Revenue Service and to each Non-United States Holder the amount
of dividends paid to such holder and any tax withheld with respect to such
dividends. These information reporting requirements apply regardless of whether
withholding is required. Copies of the information returns reporting such
dividends and withholding may also be made available to the tax authorities in
the country in which the Non-United States Holder is a resident under the
provisions of an applicable income tax treaty or agreement.

United States backup withholding (which generally is withholding tax imposed
at the rate of 31% on certain payments to persons that fail to furnish certain
information under the United States information reporting requirements)
generally will not apply to (i) dividends paid to Non-United States Holders that
are subject to the 30% withholding discussed above (or that are not so subject
because a tax treaty applies that reduces or eliminates such 30% withholding) or
(ii) under current law, dividends paid to a Non-United States Holder at an
address outside of the United States. However, under proposed United States
Treasury regulations, in the case of dividends paid after December 31, 1997
(December 31, 1999 in the case of dividends paid to accounts in existence on or
before the date that is 60 days after the proposed United States Treasury
regulations are published as final regulations), a Non-United States Holder
generally would be subject to backup withholding at a rate of 31% unless certain
procedures or documentary evidence procedures, as applicable, are complied with,
directly or through an intermediary.

Backup withholding and information reporting generally will apply to
dividends paid to addresses inside the United States on shares of Common Stock
to beneficial owners that are not "exempt recipients" and that fail to provide
in the manner required certain identifying information.

The payment of the proceeds of the disposition of Class A Common Stock to or
through the U.S. office of a broker is subject to information reporting unless
the disposing holder, under penalty of perjury, certifies its Non-United States
status or otherwise establishes an exemption. Generally, U.S. information
reporting and backup withholding will not apply to a payment of disposition
proceeds if the payment is made outside the U.S. through a Non-United States
office of a Non-United States broker. However, information reporting
requirements (but not backup withholding) will apply to a payment of disposition

69
<PAGE>
proceeds outside the U.S. if (a) the payment is made through an office outside
the U.S. of a broker that is either (i) a U.S. person, (ii) a foreign person
which derives 50% or more of its gross income for certain periods from the
conduct of a trade or business in the U.S., or (iii) a "controlled foreign
corporation" for U.S. Federal Income tax purposes and (b) the broker fails to
maintain documentary evidence that the holder is a Non-United States Holder and
that certain conditions are met, or that the holder otherwise is entitled to an
exemption.

Backup withholding is not an additional tax. Rather, the tax liability of
persons subject to backup withholding will be reduced by the amount of tax
withheld. If withholding results in an overpayment of taxes, a refund may be
obtained, provided that the required information is furnished to the Internal
Revenue Service.

FEDERAL ESTATE TAXES

An individual Non-United States Holder who is treated as the owner of or has
made certain lifetime transfers of an interest in the Class A Common Stock will
be required to include the value thereof in his gross estate for U.S. Federal
estate tax purposes, and may be subject to U.S. Federal estate tax unless an
applicable estate tax treaty provides otherwise.

CONSEQUENCES TO THE COMPANY

LIMITATION ON USE OF NET OPERATING LOSSES

Under Section 382 of the Code, if the percentage of stock (by value) of a
corporation (the "Loss Corporation") that is owned by one or more "five-percent
shareholders" has increased by more than 50 percentage points over the lowest
percentage of stock owned by the same shareholders during a three year testing
period (an "ownership change"), the use of pre-ownership change net operating
losses of the Loss Corporation following such Ownership Change will be limited
based on the value of the Loss Corporation on the date the Ownership Change
occurs (a "Section 382 Limitation"). As of the end of its most recent taxable
year, the Company had net operating losses that are currently subject to Section
382 Limitations. Although the Company believes that the issuance of the Common
Stock should not result in an Ownership Change, future equity issuances or
transactions among shareholders may trigger an Ownership Change. If such an
Ownership Change occurs, the Company's use of its net operating losses will be
subject to a Section 382 Limitation based on the value of the Company on the
date of such an Ownership Change.

The financial statements of the Company do not reflect a provision for
Federal income taxes for the year ended December 31, 1996. A full valuation
allowance has been recorded in the financial statements against the net deferred
tax asset as its realization is uncertain.

THE FOREGOING DISCUSSION IS INCLUDED FOR GENERAL INFORMATION ONLY.
ACCORDINGLY, EACH PROSPECTIVE PURCHASER IS URGED TO CONSULT HIS TAX ADVISOR WITH
RESPECT TO THE UNITED STATES FEDERAL INCOME TAX AND FEDERAL ESTATE TAX
CONSEQUENCES OF THE OWNERSHIP AND DISPOSITION OF CLASS A COMMON STOCK, INCLUDING
THE APPLICATION AND EFFECT OF THE LAWS OF ANY STATE, LOCAL, FOREIGN, OR OTHER
TAXING JURISDICTION.

REPORT OF INDEPENDENT AUDITORS

To the Board of Directors and Shareholders of
Metromedia Fiber Network, Inc.

We have audited the accompanying consolidated balance sheet of Metromedia
Fiber Network, Inc. (formerly National Fiber Network, Inc.) and Subsidiary (the
"Company") as of December 31, 1996, and the related consolidated statements of
operations, stockholders' deficiency 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 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 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 consolidated financial position of
Metromedia Fiber Network, Inc. (formerly National Fiber Network, Inc.) and
Subsidiary as of December 31, 1996, and the consolidated results of their
operations and their cash flows for the year then ended in conformity with
generally accepted accounting principles.

REPORT OF INDEPENDENT AUDITORS

To the Board of Directors and Shareholders of
Metromedia Fiber Network, Inc.

We have audited the accompanying consolidated balance sheet of Metromedia
Fiber Network, Inc. (formerly National Fiber Network, Inc.) (a Delaware
corporation) and Subsidiary (the "Company") as of December 31, 1995, and the
related consolidated statements of operations, stockholders' deficiency 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.

In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
Metromedia Fiber Network, Inc. (formerly National Fiber Network, Inc.) and
Subsidiary as of December 31, 1995, and the consolidated results of their
operations and their cash flows for the year then ended in conformity with
generally accepted accounting principles.

The accompanying consolidated financial statements have been prepared
assuming that the Company will continue as a going concern. As discussed in Note
1 to the consolidated financial statements, the Company's significant recurring
losses, operating history and significant working capital deficiency, including
significant amounts of past due payables, raise substantial doubt about the
Company's ability to continue as a going concern. Management's plans in regard
to these matters are also discussed in Note 1. The consolidated financial
statements do not include any adjustments relating to the recoverability and
classification of recorded asset amounts or the amounts and classification of
liabilities that might result from the outcome of this uncertainty.

REPORT OF INDEPENDENT AUDITORS

To the Board of Directors and Shareholders of
Metromedia Fiber Network, Inc. (formerly National Fiber Network, Inc.)

We have audited the accompanying statements of operations, changes in
stockholders' (deficiency) equity and cash flows of Metromedia Fiber Network,
Inc. (formerly National Fiber Network, Inc.) for the year ended December 31,
1994. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audit.

We conducted our audit in accordance with 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 financial statements enumerated above present fairly, in
all material respects, the results of operations of Metromedia Fiber Network,
Inc. (formerly National Fiber Network, Inc.) and its cash flows for the year
ended December 31, 1994 in conformity with generally accepted accounting
principles.

The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern. As discussed in Note 1 to the
financial statements, the Company has incurred net losses and significant
construction costs and will require additional financing. These issues raise
substantial doubt about its ability to continue as a going concern. Management's
plans in regard to these matters are also discussed in Note 1. The financial
statements do not include any adjustments that might result from the outcome of
this uncertainty.

BUSINESS OPERATIONS AND LINE OF BUSINESS

Metromedia Fiber Network, Inc. (formerly National Fiber Network, Inc.) and
its subsidiary, National Fiber Network of New Jersey, Inc. (the "Company"), was
a development stage company for the period from inception (April 8, 1993)
through October 1995. Effective December 20, 1993, the Company was granted a
nonexclusive right from the City of New York to provide telecommunication
services and construct a fiber optic network for the purpose of providing these
services. In October 1995, the basic backbone of the Fiber Optic Cable Network
was completed and the Company began servicing its customers.

The Company incurred significant costs in connection with the construction
of the initial backbone of the fiber optic network and expects to continue to
incur more costs when the Company extends its network construction.

BASIS OF CONSOLIDATION

The consolidated financial statements include the accounts of the Company.
All material intercompany balances and transactions have been eliminated in
consolidation.

BASIS OF PRESENTATION

The accompanying consolidated financial statements have been prepared on a
going concern basis which contemplates the realization of assets and the
satisfaction of liabilities in the normal course of business. Since inception,
the Company has suffered significant recurring losses and, as of December 31,
1996, the Company had a working capital deficiency of approximately $12,887,000
and a stockholders' deficiency of approximately $6,858,000. Further, at December
31, 1996, substantially all of its trade payables and certain current
liabilities were past due. In addition, the Company was not in compliance with
certain debt and settlement agreements. These factors, raised substantial doubt
about the Company's ability to continue as a going concern. On April 30, 1997
the Company sold 8,403.325 shares of Series B preferred shares in exchange for
$32,500,000 in cash. A portion of the cash was used to satisfy the
aforementioned obligations. Management believes that these funds are sufficient
to meet the Company's obligations for at least the next year.

ESTIMATES

The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

RECOGNITION OF REVENUE

The Company recognizes revenue on telecommunications services ratably over
the term of the applicable agreements with customers.

DEFERRED REVENUE

Deferred revenue represents prepayments received from customers for future
use of the Company's fiber optic network.

ORGANIZATION COSTS

Costs incurred in connection with the organization of the Company were
capitalized and are being amortized over five years on a straight-line basis.

NON RECURRING CONSULTING AND EMPLOYMENT INCENTIVES

The amounts represent the value of common stock, warrants and options issued
to consultants and officers of the Company as incentive for the consultants and
officers to provide services to the Company.

The 1997 amounts represent the value of 3,000,000 shares and options to
purchase 1,680,000 shares of the Company's common stock issued in 1997 to
executive officers of the Company in connection with each entering into
employment agreements. The options have been valued in accordance with APB
Opinion No. 25, "Accounting for Stock Issued to Employees" at the difference
between the exercise price of the options and the fair market value of the
Company's common stock.

STOCK-BASED COMPENSATION

The Company has adopted the disclosure-only provisions of SFAS No. 123,
"Accounting for Stock-Based Compensation". The Company applies APB Opinion No.
25, "Accounting for Stock Issued to Employees", and related interpretations in
accounting for its stock options.

FIBER OPTIC TRANSMISSION NETWORK AND RELATED EQUIPMENT

The fiber optic transmission network and related equipment are stated at
cost. Various costs are capitalized during the installation and expansion of the
network. Depreciation is computed using the straight-line method through the
expiration date of the franchise agreement, December 20, 2008.

LONG LIVED ASSETS

In fiscal 1996, the Company adopted SFAS No.121, "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed of".
The Company reviews for the impairment of long-lived assets and certain
identifiable intangibles whenever events or changes in circumstances indicate
that the carrying amount of an asset may not be recoverable. No such impairment
indicators have been identified by the Company.

PROPERTY AND EQUIPMENT

Property and equipment are stated at cost. Depreciation is computed using
the straight-line and accelerated cost recovery methods over the shorter of the
estimated useful lives of the assets or the term of the lease.

FRANCHISE COSTS

Amortization of franchise costs began upon commencement of service to
customers and is computed on the straight-line method through December 20, 2008
(159 months), the expiration date of the franchise agreement.

INCOME TAXES

The Company recognizes deferred tax liabilities and assets, if any, for the
expected future tax consequences of events that have been included in the
financial statements or tax returns. Under this method, deferred tax liabilities
and assets are determined based on the difference between the financial
statement and tax bases of assets and liabilities using enacted tax rates in
effect for the year in which the differences are expected to reverse. Valuation
allowances are provided when the expected realization of tax assets does not
meet a more likely than not criterion.

CASH AND CASH EQUIVALENTS

For purposes of the consolidated statement of cash flows, the Company
considers all highly liquid investments with an original maturity of three
months or less when purchased to be cash equivalents.

RECAPITALIZATION

In April 1997, the Company increased its authorized common stock of $.01 par
value to 60,000,000 shares; in addition, authorized preferred stock with a par
value of $.01 was increased to 2,000,000 shares.

On February 17, 1995, the Company effected a 4,000 for one stock split of
its outstanding shares of common stock. The financial statements give
retroactive effect to this stock split.

On April 29, 1997, the Company effected a 3 for one stock split of its
outstanding shares of common stock. The financial statements give retroactive
effect to this stock split.

EARNINGS PER SHARE

Net loss per share computations are based upon net loss divided by the
weighted average number of shares of common stock outstanding during the
respective periods. The weighted average number of common shares outstanding
have been calculated in accordance with Staff Accounting Bulletin 83 ("SAB 83")
of the Securities and Exchange Commission. SAB 83 requires that shares of common
stock and options issued one-year prior to the initial filing of a registration
statement relating to an initial public offering at amounts below the public
offering price be considered outstanding for all periods presented in the
Company's registration statement. In computing the effect of stock options,
using the treasury stock method, the Company assumed that the market value of
the stock was $3.87 per share.

UNAUDITED INFORMATION

The unaudited financial statements at June 30, 1997 and for the six months
ended June 30, 1996 and 1997 reflect adjustments, all of which are of a normal
recurring nature, which are, in the opinion of management, necessary to a fair
presentation. The results for the interim periods presented are not necessarily
indicative of full year results.

aggregate borrowings of $2,500,000 consisting of the following: (i) working
capital advances of $1,500,000, and (ii) equipment and materials procurement
of $1,000,000. A supplemental agreement executed on July 11, 1995 increased

line of credit of $2,850,000. As of December 31, 1995, the Company had
outstanding borrowings aggregating $2,850,036.

All amounts advanced under this agreement were scheduled to mature on April

1.75%. The outstanding balance was collateralized as follows: (i) a security
interest in the assets of the Company, (ii) a pledge of shares of common
stock of the Company personally owned by the Company's president, and (iii)
the personal guaranty of the Company's president.

The agreement also provided for the Company to reimburse Tomen for certain
transaction expenses. As of December 31, 1995, a total of $152,604 of such
costs was included in accrued expenses.

On April 16, 1996, the Company repaid the entire principal balance, all
accrued and unpaid interest, and all expenses concurrent with the execution
of the refinancing agreement with U.S. One Communications.

b) On March 16, 1995, the Company entered into a loan agreement with one of the
Company's directors for $500,000 bearing interest at 10% per annum, due on
March 16, 1996. As an inducement for entering into this loan agreement, the
Company issued 307,680 shares of common stock. This share issuance was
recorded at an amount equal to the value of the discounted interest rate
that the note bears over the term of the loan, or $5,000. This loan was

On February 16, 1995, the Company issued to this party a warrant entitling
the holder to purchase a total of 1,319,856 shares of the Company's common
stock. This warrant, was canceled and replaced by a new warrant issued on

purchase price of $2.46 per share. The new warrant expires on February 13,
2000.

d) On April 16, 1996, the Company entered into an agreement with U.S. One
Communications ("U.S. One") for the exclusive usage rights for 8 to 12
fibers on the Company's fiber optic transmission network. The initial term
of the agreement was for a period beginning April 1996 and expiring December
2008. The agreement was renewable, at the option of U.S. One, for an
extended term of 13 years expiring December 2021. Concurrent with the
execution of the original agreement, the Company and U.S. One entered into a
bridge financing agreement. This was done for the purpose of refinancing the
Company's existing indebtedness to Tomen America and to obtain additional
funding until the construction borrowing arrangement was secured. In
connection with this agreement, the Company borrowed $4,900,000 from U.S.
One, of which $3,227,867 was immediately used to repay all amounts owed to
Tomen America as of April 16, 1996.

On April 30, 1997 the Company amended this agreement which allows U.S. One
to have the exclusive right to use 888 fiber miles of the network.
Additionally, pursuant to the amended agreement, U. S. One received an
option to acquire from the Company up to 1,620 additional fiber miles upon
payment of a predetermined amount. In accordance with the amended agreement
the following occurred: (i) all interest accrued from the inception of the
bridge loan to the closing date of the agreement was waived by U.S. One, and
(ii) the $4,900,000 principal balance of the loan was offset against the
$3,530,000 scheduled payment due from U.S. One to the Company under the
amended lease agreement. (iii) the Company paid to U.S. One the difference
of $1,370,000 on April 30, 1997 with proceeds from the Metromedia

event shall the aggregate purchase price exceed $1,250,000.

e) On September 24, 1996, the Company entered into a loan agreement with
Sterling Capital ("Sterling") for $550,000. The loan bears interest at 10%
per annum and matures on March 1, 1997. The loan was secured by all of NFN's
assets and was subordinated to the aforementioned U.S. One loan. As an
incentive for the loan, NFN issued to Sterling warrants to purchase 186,000
shares of common stock at an exercise price of $3.00. The warrants can be
exercised on the later of (i) the third anniversary or (ii) twelve months
after the Company has completed a public offering. On May 1, 1997 the
Company repaid the loan in full and all accrued interest with proceeds from
the sale of convertible preferred stock to Metromedia.

6. SENIOR SUBORDINATED NOTES

On March 19, 1996, a supplemental investment agreement was executed with the
same investor providing for an additional advance of $500,000 with the same

Concurrent with the issuance of these notes, warrants were issued by the
Company to the noteholders which were exercisable for common shares of the
Company in an amount equal to 0.7% of the outstanding shares of common stock

common stock equal to 0.7% of the common stock then issued and outstanding,
in exchange for the surrender and cancellation of the outstanding warrants,
and in consideration for the extension of the maturity date of the notes

services effectively terminated prior to December 31, 1995. Accordingly, as of
December 31, 1995, the Company recorded $876,146 as a liability in accordance
with the terms of the settlement agreement.

The settlement agreement also reaffirmed the option previously issued to
this former officer on May 1, 1995, which entitles the holder to purchase
410,025 shares of the Company's common stock at $.003 per share through February
1, 1999. In 1997 the Company repurchased and retired the warrant.

On November 14, 1996, the Company amended the above referenced settlement
agreement with the former officer, whereby a consultant to the Company agreed to
purchase common stock of the Company from the former officer and certain of his
affiliates in exchange for $640,000 and the complete satisfaction of the
aforementioned liability.

On February 11, 1997, the Company entered into an agreement (the

prior agreements with the Company, and the consultant/director agreed to release
the Company from any claims against the Company.

9. STOCK ISSUED TO LEGAL COUNSEL

On January 12, 1996, the Company entered into an agreement with its legal
counsel which calls for the issuance by the Company of common stock as
additional consideration for legal services provided. Pursuant to this
agreement, and the subsequent amendment dated April 16, 1996, the Company issued
a total of 968,649 shares during March and April of 1996. Management has
estimated that the value of the 968,649 shares issued is equal to $907,301 and
has recorded a noncash charge in connection with such issuance.

10. STOCK TRANSACTIONS

COMMON STOCK

In June 1996, the Company sold a total of 75,000 shares of common stock to

these shares, warrants were issued by the Company to these shareholders
entitling the holders to purchase a total of 75,000 shares at $1.33 per share
for a three year period. In the event of an initial public offering of the
Company's common stock during the exercise period, the exercise price will be
reduced to the lesser of $1.33 or 50% of the per share price of the initial
public offering.

h. A former investment advisor to the Company has made a claim in the amount of
$305,731 pursuant to an agreement made on June 27, 1995, for the payment of
certain fees and expenses. The Company has rejected the claim based on the
failure of the investment advisor to properly perform its services and
fiduciary duties. Accordingly, the Company has not made provision in the
consolidated financial statements for this claim.

i. On or about April 18, 1997, Howard Katz, Realprop Capital Corp. and Evelyn
Katz commenced an action against, among others, the Company and Stephen A.
Garofalo in the United States District Court for the Southern District Court
of New York captioned KATZ, ET AL. v. NATIONAL FIBER NETWORK, INC., ET AL.,
No. 97 Civ. 2764 (JGK) (the "Katz Litigation"). (National Fiber Network,
Inc. is the former name of the Company). On May 28, 1997, the plaintiffs
filed an amended complaint. The amended complaint alleges causes of action
for, among other things, common law fraud, violations of Section 10(b) of
the Securities Exchange Act of 1934 and Rule 10b-5 promulgated thereunder,
breach of fiduciary duty and negligent misrepresentation for alleged
misrepresentations and omissions made in connection with the repurchase of
the Katz Securities (as defined below under "Certain Relationships and
Related Transactions"). The amended complaint also contains allegations of
corporate waste against the Company and Mr. Garofalo. Plaintiffs seek, among
other things, compensatory damages of not less than $4.5 million,
unspecified punitive damages and, in the alternative, rescission. On June
11, 1997, various defendants, including the Company and Stephen A. Garofalo
moved to dismiss the amended complaint. The Company intends to vigorously
defend itself against these allegations based on its belief that MFN acted
appropriately in connection with the matters at issue in this litigation. No
assurance can be made, though, that the Company will not determine that the
advantages of entering into a settlement outweigh the risks and expense of
protracted litigation or that ultimately the Company will be successful in
its defense of the allegations.

13. METROMEDIA TRANSACTIONS

Through April 30, 1997, Metromedia loaned the Company an aggregate of
$4,000,000. On April 30, 1997, the Metromedia Loan was repaid with a portion of
the proceeds from the Metromedia Investment. The Metromedia Loan bore interest
at the prime rate announced by The Chase Manhattan Bank and was convertible into
Common Stock based on a formula if the principle and interest was not repaid in
full by August 31, 1997.

A portion of the proceeds from the Metromedia Loan were used to fund an
escrow account which repurchased on behalf of the Company, 1,160,691 shares of
Common Stock and warrants to purchase 410,025 shares of Common Stock. Pursuant
to an escrow arrangement, such securities were pledged to Metromedia as security
for the Loan.

On April 30, 1997, the Company sold an aggregate of 8,403.325 shares of
series B convertible preferred stock to Metromedia and affiliates, for an
aggregate purchase price of $32.5 million, (the "Metromedia Investment").

Preferred Stock and Contingent Warrants ($2,115,000), repay the Metromedia Loan
and accrued interest thereon ($4,058,127), and repay other short-term
indebtedness ($3,485,000). Upon repayment of the Metromedia Loan, the
repurchased shares were released from escrow and delivered to the Company.

Access Charge:............................... The fees paid by long distance carriers to
LECs for originating and terminating long
distance calls on the LECs' local networks.

Analog Transmission:......................... A way of sending voice, video and data
signals electronically in which the
transmitted signal is analogous to the
original signal.

ATM (Asynchronous Transfer Mode):............ An information transfer standard that is one
of a general class of packet technologies
that relay traffic by way of an address
contained within the first five bytes of a
standard fifty-three-byte-long packet or
cell. The ATM format can be used by many
different information systems, including
local area networks to deliver traffic at
varying rates, permitting a mix of voice,
data and video (multimedia).

Backbone:.................................... The backbone is the part of the
telecommunications network which carries the
most traffic. It is the through-portion of a
transmission network, as opposed to spurs
which branch off the though-potions.

Bandwidth:................................... The range of analog frequencies or digital
signals that can be passed through a
transmission medium, such as fiber optic
cable. The greater the bandwidth, the greater
the information carrying capacity. Bandwidth
is measured in Hertz (analog) or Bits Per
Second (digital).

Bit:......................................... A contraction of the term Binary Digit, it is
the basic unit in data communications. Bits
are typically represented by ones or zeros.

Capacity:.................................... The information carrying ability of a
telecommunications facility.

Central Office:.............................. Telephone company facility where subscribers'
lines are joined to switching equipment for
connecting other subscribers to each other,
locally and long distance.

Channel:..................................... A path of communication either electrical or
electromagnetic, between two or more points.
Also called a circuit, facility, line, link,
or path.

transmitting information through the use of
distinct electronic or optical pulses that
represent the binary digits 0 and 1. Digital
transmission/switching technologies employ a
sequence of discrete, distinct pulses to
represent information, as opposed to the
continuously variable analog signal.

DS-3:........................................ DS is the standard telecommunications
industry designation of a hierarchy of
digital signal speeds used to classify

Underwriters exercise such option, each of the International Underwriters and
the U.S. Underwriters, as the case may be, will be committed, subject to certain
conditions, to purchase a number of option shares proportionate to such
International Underwriter's or U.S. Underwriter's initial commitment.

The Company has entered into a U.S. Underwriting Agreement with the U.S.
Underwriters named therein, for whom Salomon Brothers Inc, Donaldson, Lufkin &
Jenrette Securities Corporation and are acting as the representatives (the
"U.S. Representatives" and, together with the International Representatives, the
"Representatives"), providing for the concurrent offer and sale of shares of
Class A Common Stock (in addition to the shares covered by the over-allotment
options described above) in the United States and Canada. Both the International
Underwriting Agreement and the U.S. Underwriting Agreement provide that the
obligations of the International Underwriters and the U.S. Underwriters are such
that if any of the shares of Class A Common Stock are purchased by the

65
<PAGE>
International Underwriters pursuant to the International Underwriting Agreement,
or by the U.S. Underwriters pursuant to the U.S. Underwriting Agreement, all the
shares of Class A Common Stock agreed to be purchased by either the
International Underwriters or the U.S. Underwriters, as the case may be,
pursuant to their respective agreements must be so purchased. The price to
public and underwriting discount per share of Class A Common Stock for the
International Offering and the U.S. Offering will be identical. The closing of
the U.S. Offering is a condition to the closing of the International Offering
and the closing of the International Offering is a condition to the closing of
the U.S. Offering.

Each International Underwriter has severally agreed that, as part of the
distribution of the shares of Class A Common Stock offered by the
International Underwriters, (i) it is not purchasing any shares of Class A
Common Stock for the account of any United States or Canadian Person and (ii) it
has not offered or sold, and will not offer or sell, directly or indirectly, any
shares of Class A Common Stock or distribute any Prospectus relating to the
International Offering to any person in the United States or Canada or to any
United States or Canadian Person. Each U.S. Underwriter has severally agreed
that, as part of the distribution of the shares of Class A Common Stock
offered by the U.S. Underwriters, (i) it is not purchasing any shares of Class A
Common Stock for the account of anyone other than a United States or Canadian
Person and (ii) it has not offered or sold, and will not offer or sell, directly
or indirectly, any shares of Class A Common Stock or distribute this Prospectus
to any person outside of the United States or Canada or to anyone other than a
United States or Canadian Person.

Pursuant to the Agreement Between U.S. Underwriters and International
Underwriters, sales may be made between the International Underwriters and the
U.S. Underwriters of such number of shares of Class A Common Stock as may be
mutually agreed. The price of any shares of Class A Common Stock so sold shall
be the public offering price, less an amount not greater than the concession to
securities dealers. To the extent that there are sales between the International
Underwriters and the U.S. Underwriters pursuant to the Agreement Between U.S.
Underwriters and International Underwriters, the number of shares of Class A
Common Stock initially available for sale by the International Underwriters or
by the U.S. Underwriters may be more or less than the amount specified on the
cover page of this Prospectus.

The International Underwriting Agreement and the U.S. Underwriting Agreement
provide that the Company will indemnify the International Underwriters and the
U.S. Underwriters against certain liabilities and expenses, including
liabilities under the Securities Act, or contribute to payments the
International Underwriters and the U.S. Underwriters may be required to make in
respect thereof.

66
<PAGE>
incentive plans of the Company existing on the date of this Prospectus, (ii)
shares issued in respect of obligations existing before the date of this
Prospectus and (iii) shares in connection with the Offerings.

At the Company's request, the International Underwriters have reserved up to
shares of Class A Common Stock (the "Directed Shares") for sale at the public
offering price to persons who are directors, officers or employees of, or
otherwise associated with, the Company and its affiliates and who have advised
the Company of their desire to purchase such shares of Class A Common Stock. The
number of shares of Class A Common Stock available for sale to the general
public will be reduced to the extent of sales of Directed Shares to any of the
persons for whom they have been reserved. Any shares of Class A Common Stock not
so purchased will be offered by the International Underwriters on the same basis
as all other shares of Class A Common Stock offered hereby.

The International Underwriters and the U.S. Underwriters do not intend to
confirm sales to any accounts over which they exercise discretionary authority.

This Company has applied to have the Class A Common Stock quoted in the
Nasdaq National Market under the proposed symbol MFBR.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS

Section 145(a) of the General Corporation Law of the State of Delaware
provides that a Delaware corporation may indemnify any person who was or is a
party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the corporation) 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 or enterprise,
against expenses, judgments, fines and amounts paid in settlement actually and
reasonably incurred by him in connection with such action, suit or proceeding if
he acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best interests of the corporation, and, with respect to any
criminal action or proceeding, had no cause to believe his conduct was unlawful.

Section 145(b) provides that a Delaware corporation may indemnify any person
who was or is a party or is threatened to be made a party to any threatened,
pending or completed action or suit by or in the right of the corporation to
procure a judgment in its favor by reason of the fact that such person acted in
any of the capacities set forth above, against expenses actually and reasonably
incurred by him in connection with the defense or settlement of such action or
suit if he acted under similar standards, except that no indemnification may be
made in respect of any claim, issue or matter as to which such person shall have
been adjudged to be liable to the corporation unless and only to the extent that
the court in which such action or suit was brought shall determine that despite
the adjudication of liability, such person is fairly and reasonably entitled to
be indemnified for such expenses which the court shall deem proper.

Section 145 further provides that to the extent a director or officer of a
corporation has been successful in the defense of any action, suit or proceeding
referred to in subsections (a) and (b) or in the defense of any claim, issue, or
matter therein, he shall be indemnified against expenses actually and

II-1
<PAGE>
reasonably incurred by him in connection therewith; that indemnification
provided for by Section 145 shall not be deemed exclusive of any other rights to
which the indemnified party may be entitled; and that the corporation may
purchase and maintain insurance on behalf of a director or officer of the
corporation against any liability asserted against him or incurred by him in any
such capacity or arising out of his status as such whether or not the
corporation would have the power to indemnify him against such liabilities under
such Section 145.

Section 102(b)(7) of the General Corporation Law provides that a corporation
in its original certificate of incorporation or an amendment thereto validly
approved by stockholders may eliminate or limit personal liability of members of
its board of directors or governing body for breach of a director's fiduciary
duty. However, no such provision may eliminate or limit the liability of a
director for breaching his duty of loyalty, failing to act in good faith,
engaging in intentional misconduct or knowingly violating a law, paying a
dividend or approving a Stock repurchase which was illegal, or obtaining an
improper personal benefit. A provision of this type has no effect on the
availability of equitable remedies, such as injunction or rescission, for breach
of fiduciary duty. The Company's Charter contains such a provision.

The Company's Charter further provides that the Company shall indemnify its
officers and directors and, to the extent authorized by the Board, employees and
agents of the Company, to the fullest extent permitted by and in the manner
permissible under the laws of the State of Delaware.

ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES

During the past three years, the Company has issued the following
securities, none of which have been registered under the Securities Act.

As of December 31, 1995, the Company owed its majority shareholder $896,979.
Pursuant to an agreement dated May 21, 1996, the Company issued 300,000 shares
of its Class A Common Stock to the majority shareholder in consideration for the
cancellation of a portion of the outstanding balance.

The Company engaged the services of an electrical contractor controlled by
the Company's majority shareholder in connection with the construction of the
fiber optic network. As of December 31, 1995, the entire $692,887 was owed to
this related company. In May 1996, the Company and the assignee of this related
party entered into an agreement whereby the full amount of this indebtedness was
satisfied by the issuance of 900,000 shares of the Company's Class A Common
Stock.

On May 1, 1995, the Company issued Option Warrants to Realprop for 410,025
shares of Class A Common Stock at $.01 per share, exercisable prior to February
1, 1999. The warrants were redeemed by the Company as part of the Katz
Securities.

On March 16, 1995, the Company entered into the Rubin Loan Agreement with
one of the Company's directors for $500,000 bearing interest at 10% per annum
due on March 16, 1996. As an inducement for entering into this loan agreement,
the Company issued to the director 307,680 shares of Class A Common Stock.

On April 18, 1995, the Company entered into a loan agreement with a customer
for $500,000 bearing interest at 11% per annum, originally due 120 days from the
date of this loan. Pursuant to a supplemental agreement dated January 12, 1996,
the parties agreed to extend the maturity date of this loan to November 18,
1996. Pursuant to a second supplemental agreement dated March 1997, the parties
agreed to extend the maturity date to June 30, 1997. On February 16, 1995, the
Company issued to this party a warrant entitling the holder to purchase a total

cancelled and replaced by a new warrant issued on February 13, 1997 for 900,000
nonassessable shares of Class A Common Stock at a purchase price of $2.46 per
share. The new warrant expires on February 13, 2000.

II-2
<PAGE>
On April 16, 1996, the Company entered into an agreement with US ONE for the
lease of exclusive usage rights for 8 to 12 fibers on the Company's fiber optic
transmission network. On April 30, 1997, the Company amended this agreement.
Concurrent with the execution of the original lease agreement, the Company and
US ONE entered into a bridge financing agreement. Concurrent with the execution
of the aforementioned lease and bridge financing agreements, the Company entered
into a letter agreement with US ONE providing for the sale of a warrant to
purchase Class A Common Stock of the Company. Under this agreement, the warrant
is exercisable for a number of shares to be determined at the Company's
discretion subject to a minimum number of 150,000 shares and a maximum number of
900,000 shares. The per share exercise price is to be determined pursuant to a
formula, but in no event shall the aggregate purchase price exceed $1,250,000.

On September 24, 1996, the Company entered into a loan agreement with
Sterling for $550,000. As an incentive for the loan, MFN issued to Sterling
warrants to purchase 186,000 shares of Class A Common Stock at an exercise price
of the lesser of $3.00 per share, the price at which the Company shall issue its
securities in the future less $3.00, or one half the price at which the Class A
Common Stock of the Company is offered in an initial public offering. The
warrants can be exercised at the later of (i) the third anniversary or (ii)
twelve months and 90 days after the Company has completed a public offering.

On February 13, 1996, the Company entered into an investment agreement with
an individual (the "Investor") pursuant to which the Company borrowed $1,000,000
in consideration for the issuance of 12% senior subordinated promissory notes
maturing on November 1, 1996. The notes were convertible at a price of $1.33 per
unit for each $1,000 of principal outstanding. Each unit consists of the
following: (i) one share of Class A Common Stock, and (ii) one warrant to
purchase one share of Class A Common Stock at $2.67 per share. As an inducement
for entering into the investment agreement, the Company issued to the investor
the following: (i) 751,650 fully paid shares of Class A Common Stock, and (ii) a
warrant to purchase 751,650 shares of Class A Common Stock at $2.67 per share,
exercisable for a five year period beginning August 15, 1997 and ending August
15, 2002. On March 19, 1996, a supplemental investment agreement was executed
with the same investor providing for an additional advance of $500,00 with the
same maturity date, interest rate, conversion rights, and guaranty features as
the initial $1,000,000 investment. This advance was subsequently repaid, along
with interest on April 16, 1996. In connection with this supplemental agreement,
the Company issued a warrant to purchase 375,825 shares of Class A Common Stock
at $2.67 per share, exercisable for a five year period beginning on August 15,
1997 and expiring August 15, 2002. The Company also issued a warrant to purchase
an additional 375,825 shares at $0.003 per share (the "Penny Warrants"),
exercisable for a period beginning August 15, 1997 and expiring August 15, 2002.
On April 11, 1996, a memorandum of understanding was entered into between the
parties pursuant to which the warrants issued on February 13, 1996 to purchase
751,650 shares at $2.67 per share and the warrants issued on March 19, 1996 to
purchase 375,825 shares at $2.67 per share were surrendered by the investor to
the Company in consideration for the issuance of 450,000 shares of the Company's
Class A Common Stock. In April and July 1996, the investor purchased 300,000 and
75,825 shares of Class A Common Stock, respectively, at $.003 per share in
connection with an exercise of the Penny Warrants. The Company granted the
investor the right to exercise prior to the stated exercise period. Further, in
accordance with the investment agreement an additional 75,000 shares of Class A
Common Stock was issued to the investor in compliance with the anti-dilutive
requirements in the agreement.

In August 1995, the Company initiated a $600,000 private offering of
subordinated notes. Those notes were scheduled to mature in March 1996 and bear
interest at an annual rate of 15%, payable quarterly in arrears. Concurrent with
the issuance of these notes, warrants were issued by the Company to the
noteholders which were exercisable for common shares of the Company in an amount
equal to 0.7% of the outstanding shares of Class A Common Stock immediately
following an initial public offering of the Company's Class A Common Stock, at
an exercise price equal to 60% of the initial public offering price. These
warrants are exercisable over a three-year period beginning on the effective
date of such

II-3
<PAGE>
initial public offering. In April 1996, the Company offered the warrant holders
fully paid shares of Class A Common Stock equal to 0.7% of the Class A Common
Stock then issued and outstanding, in exchange for the surrender and
cancellation of the outstanding warrants, and in consideration for the extension
of the maturity date of the notes through June 30, 1996. All of the warrant
holders accepted this offer and accordingly, the Company issued a total of
117,078 shares of the Company's Class A Common Stock.

In October 1995, the Company initiated a private offering of $858,000 of
convertible subordinated notes. Through December, 1995, $783,000 of convertible
notes were sold pursuant to this offering, and an additional $75,000 of notes
were sold during January and February of 1996. These notes were scheduled to
mature during the period October 1996 through February 1997 and bear interest at
an annual rate of 15%, payable at maturity. The notes are convertible, at the
Company's option, at any time into shares of Class A Common Stock at a rate of
three shares of Class A Common Stock per $1,000 of note principal, at a
conversion price equal to 60% of the per share price of an initial public
offering of the Company's Class A Common Stock. Concurrently with the issuance
of these notes, warrants were issued by the Company to the noteholders which are
exercisable at a rate of 30,000 shares of Class A Common Stock per $100,000 of
note principal. Such warrants, entitling the holders to purchase an aggregate of
257,400 shares, are exercisable at a price equal to 50% of the per share price
of an initial pubic offering of Class A Common Stock over a three-year period
beginning on the effective date of such public offering.

In December 1996, the Company offered the private placement noteholders
Common Stock purchase warrants to purchase 211,200 shares of its Class A Common
Stock exercisable at one half of the price for which shares are sold in an
initial public offering for a period of three years following such offering in
exchange for the extension of the due dates of the notes. All of the noteholders
accepted this offer.

On January 12, 1996, the Company entered into an agreement with its then
legal counsel which called for the issuance by the Company of Class A Common
Stock as additional consideration for legal services provided. Pursuant to this
agreement, and a subsequent amendment dated April 16, 1996, the Company issued a
total of 968,649 shares during April and March of 1996.

In June 1996, the Company sold a total of 75,000 shares of Class A Common
Stock to two individuals for total proceeds of $100,000. Concurrent with the
issuance of these shares, warrants were issued by the Company to these
shareholders entitling the holders to purchase a total of 75,000 shares at $1.33
per share for a three year period. In the event of an initial public offering of
the Company's Class A Common Stock during the exercise period, the exercise
price will be reduced to the lesser of $1.33 or 50% of the per share price of
the initial public offering.

In July 1996, the Company issued 24,000 shares of Class A Common Stock as
consideration for consulting services. In addition, the Company issued 297,000
shares to three employees for services rendered. The transaction was later
rescinded and the shares were returned to the Company.

In August 1996, the Company issued 360,000 shares of Class A Common Stock
for consulting services to an individual.

In September 1996, the Company sold 21,567 shares of Class A Common Stock to
three individuals for total proceeds of $23,500.

On April 15, 1996, the Company entered into a stock purchase agreement with
VCNY. Pursuant to this agreement, the Company issued 3,000,000 shares of Class A
Common Stock to VCNY as consideration for services provided by VCNY.

In June 1996, the Company granted 300,000 Class A Common Stock purchase
warrants to the Company's legal counsel exercisable at $.03 per share for a
period of four years as additional consideration for legal services provided.
This warrant was exercised in January 1997.

On December 13, 1996, the Company issued and sold to Penny Lane Partners,
L.P. ("Penny Lane"), for aggregate cash consideration of $2,025,000, (i) 150,000
shares of 10% cumulative convertible preferred Stock (the "Series A Preferred

to purchase 225,000 shares of Class A Common stock at an exercise price of $2.50
per share (the "Penny Lane Warrants") and (iii) a contingent Stock subscription
warrant to purchase a number of shares of Class A Common Stock (such number to
be determined based on certain future events) at an exercise price of $0.01 per
share (the "Contingent Warrants"), In March 1997, Penny Lane agreed to permit
the Series A Preferred Stock and the Contingent Warrants to be redeemed at an
aggregate redemption price of $2,115,000 (which includes accrued but unpaid
dividends on the Series A Preferred Stock) and in connection therewith the
number of Penny Lane Warrants was increased from 225,000 to 450,000.

In April 1997, the Company granted to an officer 3,000,000 shares of Class A
Common Stock.

Through April 30, 1997, Metromedia loaned the Company an aggregate of
$4,000,000. The Metromedia Loan bore interest at the prime rate announced by The
Chase Manhattan Bank and was convertible into Class A Common Stock based on a
formula if the principal and interest was not repaid in full by August 31, 1997.
On April 30, 1997, the Metromedia Loan was repaid with a portion of the proceeds
from the Metromedia Investment.

On April 30, 1997, the Company sold an aggregate of 8,403.325 shares of

the Securities Act in reliance on the exemption from registration provided
pursuant to Section 4(2) and Regulation D promulgated thereunder.

ITEM 17. UNDERTAKINGS

Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
registrant pursuant to the provisions described under Item 15 above, 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 and is, therefore, unenforceable. In the event
that a claim for indemnification for 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

II-6
<PAGE>
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 Securities
Act and will be governed by the final adjudication of such issue.

The undersigned registrant hereby undertakes:

(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 a
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 agreements certificates in such denominations and registered in
such names as required by the Underwriters to permit prompt delivery to each
purchaser.
