  The following information is a summary of the more detailed information and
financial statements appearing elsewhere or incorporated by reference in this
Prospectus and is qualified in its entirety by reference thereto. Unless
otherwise indicated, all information contained in this Prospectus assumes that
the Underwriters' over-allotment options will not be exercised.
 
  See "Glossary" for definitions of certain other terms used in this
Prospectus.
 
                                  THE COMPANY
 
  MFS is an integrated communications provider ("ICP") of local and long
distance telecommunications services and certain Internet-related services to
business and government end users. The Company provides services by utilizing a
combination of its own facilities and network capacity leased from others
(taken together, the "International Network Platform") in the United States,
Western Europe and Asia. As the first ICP to focus on business and government
customers, the Company believes it is uniquely positioned to take advantage of
technical, regulatory and market changes which promote demand for an integrated
set of communications services.
 
  The Company's strategy is to become the premier provider of communications
services to business and government end users. The Company believes business
and government end users have distinct communications service requirements,
including maximum reliability, consistent high quality, responsive customer
service and continuous attention to service enhancement and new service
development. The Company believes it has multiple advantages over its
competitors as a result of the Company's: (i) focus on business and government
end users; (ii) expertise in developing and operating highly reliable, advanced
digital fiber optic networks which offer substantial transmission capacity;
(iii) emphasis on providing comprehensive and responsive customer service; (iv)
International Network Platform that serves customers with multiple offices in
key international business centers; (v) network development plan which helps
assure an efficient evolution from a voice-oriented, circuit switched network
to a packet switched network supporting Internet and other protocols (an "IP
Packet") switched network; (vi) plan to develop new services, including voice
service to be provided over an IP Packet switched network; and (vii) ability to
bundle local, long distance telecommunications services and Internet-related
services provided over an end-to-end network controlled by the Company.
 
  As part of the implementation of its IP Packet switched network and Internet-
based service offering plans, the Company entered into an Agreement and Plan of
Merger (the "Merger Agreement") with UUNET on April 29, 1996 pursuant to which
UUNET will become a wholly owned subsidiary of MFS (the "Merger"). There can be
no assurance that the Merger will be consummated. See "Risk Factors--Risk That
Merger May Not Be Consummated" and "Description of the Merger."
 
  The Company is organized as a holding company and operates through its
subsidiaries in two business segments: telecommunications services and network
systems integration.
 
 Telecommunications Services
 
  . The MFS Telecom Companies serve the needs of large businesses and
    government customers by providing dedicated circuits, local switched
    services and high speed data communications for large corporations.
 
  . The MFS Intelenet Companies serve the needs of medium and small
    businesses by providing integrated local and long distance switched
    telecommunications and telecommunication management services and a
    variety of value-added services including voice mail, calling card and
    specialized call accounting.
 
                                       4
<PAGE>
 
  . MFS International serves the needs of communications intensive national
    and multinational corporations in global financial centers, primarily in
    Western Europe, by providing a full range of local, long distance,
    international and data communications services as permitted by regulation
    in the relevant jurisdiction.
 
  . MFS Global Network Services expands and manages the Company's
    International Network Platform which consists of the Company's own
    facilities and switching platform as well as capacity leased from other
    service providers.
 
  . After the Merger, through UUNET the Company will provide a wide range of
    Internet-related services tailored to the needs of business and
    government users, including a comprehensive range of dial-up and
    dedicated Internet access options, consulting services and Web server
    hosting and integration services.
 
 Network Systems Integration
 
  MFS Network Technologies provides network systems integration for MFS and
third parties which desire to deploy sophisticated networks, including
intelligent transportation systems, voice and data networks, interactive
distance learning networks, security systems and combined cable television-
telephone networks.
 
RECENT DEVELOPMENTS
 
  The pace of regulatory and technical change in the telecommunications
industry has continued to accelerate. The Telecommunications Act of 1996 (the
"Telecom Act") was signed into law on February 8, 1996, effectively creating,
among other things, a national template under which the Company's services may
be provided on a more equal basis with incumbent local telephone companies once
the Telecom Act is implemented. Technical change has also been dramatic,
particularly with respect to Internet-related products and services, as a
rapidly growing amount of information available on both the Internet and on
privately managed "intranets" is made increasingly accessible with advanced
software and hardware. MFS has responded to these developments with several new
initiatives.
 
 The Telecommunications Act of 1996
 
  The Telecom Act has a number of provisions that affect the Company's
operations in ways that are difficult to predict with precision. The Company
believes that the Telecom Act is generally pro-competitive and will, on
balance, benefit the Company by, among other things, opening local exchange
markets to competition, preempting anti-competitive state laws and granting the
Company regulatory status more equal with that of the incumbent local telephone
companies. The Company believes the following attributes of the Telecom Act
will have certain positive effects on the Company's operations.
 
  . Market access. Opening all U.S. markets to local competition.
 
  . Network interconnections. Enabling the Company to more fully interconnect
    its networks with incumbent local telephone companies and other carriers
    to allow the Company to reach customers not physically connected to its
    own networks in a more cost effective manner.
 
  . Number portability. Enabling business customers to retain their existing
    phone numbers in the event they choose to switch local service providers.
    The Company considers number portability to be a significant factor which
    can positively influence a customer's decision to purchase service from
    MFS.
 
  . Reciprocal compensation. Ensuring that other carriers, both local and
    long distance, compensate the Company for calls made to its customers or,
    in the alternative, not charge the Company for calls made by its
    customers to the customers of other carriers. The Company expects such
    reciprocal compensation arrangements to improve its operating margins
    over time.
 
                                       5
<PAGE>
 
   
  The Company has moved quickly to capitalize on the anticipated benefits of
the Telecom Act. MFS has contacted 21 LECs to initiate the process of
implementing the "co-carrier" provisions of the Telecom Act as quickly as
possible and has established a co-carrier task force consisting of
approximately 100 personnel dedicated to facilitate the negotiation and
implementation of co-carrier arrangements with the LECs. On May 22, 1996, MFS
announced that it and Ameritech Corp. ("Ameritech") had entered into a
comprehensive co-carrier agreement which involves the networks of the
respective companies in the entire Ameritech marketing region, including
Illinois, Indiana, Michigan, Ohio and Wisconsin. Included in the agreement with
Ameritech are provisions relating to: interconnection at any technically
feasible point within Ameritech's network; interim number portability; access
to poles, ducts, conduits and rights-of-way controlled by Ameritech; exchange
of all local traffic at a fully reciprocal per minute rate; receipt by MFS of
terminating access charges for long distance calls made to its customers; and
nondiscriminatory access to 911 and emergency 911 services, directory
assistance services, operator call completion services and white pages
directory listings for MFS' customers.     
 
 New Infrastructure Initiatives
 
  In response to the regulatory developments embodied in the Telecom Act and
the Company's success in its previous business development initiatives, MFS
announced on May 7, 1996 a series of initiatives which, when implemented, will
expand the Company's geographic presence and service offerings in a large
number of United States metropolitan areas and certain international financial
centers. The Company anticipates that implementation of these initiatives,
including certain of the Internet-related initiatives discussed below, will,
together with currently anticipated expenditures, result in total average
annual capital expenditures of approximately $1.0 billion to $1.3 billion over
the period of implementation, which the Company expects to be up to four years.
Since a significant portion of the Company's capital expenditures are success-
based (that is, related directly to revenue growth), actual capital
expenditures may vary significantly from the above range depending on the level
of incremental sales. This range is also subject to the Company's review of a
number of factors including regulatory developments, technological developments
and market conditions. In addition, each initiative may be implemented in whole
or in part and independently of any other initiative, ensuring that the Company
retains maximum financial and operating flexibility.
 
  Construction and Expansion of Networks. The Company plans to expand the
number of U.S. metropolitan areas served to approximately 85 over the next four
years, an increase from the previously planned target of approximately 65
metropolitan areas, 45 of which are currently in operation or under active
development. In addition, the Company plans to construct approximately 35 major
expansions of existing networks. The actual number of new metropolitan areas
and network expansions constructed may vary materially from these targets.
Taken together with the aforementioned regulatory developments, MFS believes
that, upon completion, these initiatives will enable the Company to sell its
services in metropolitan areas currently containing approximately 70% of the
non-farm business employment in the United States.
 
  The Company also intends to increase the number of international financial
centers served to 45, an increase from its previously planned target of 25,
seven of which are currently operational or under active development. A number
of the financial centers are expected to be developed in Asian countries where
regulatory reform has recently created opportunities to serve the needs of
communications intensive business customers. The pace of international
development is dependent on a number of factors, many of which are beyond the
Company's control, including the speed of regulatory reform.
 
  Intercity High Capacity Network. The Company intends to build or acquire a
significant portion of its U.S. and international high speed intercity and
transoceanic fiber optic network requirements, to be
 
                                       6
<PAGE>
 
deployed over a two to four year period. In accordance with this strategy, MFS
has begun construction of intercity connections along the Eastern seaboard with
the intent of linking the Company's metropolitan networks from Washington, D.C.
to Boston. Deployment of intercity networks with high speed SONET (or
internationally, the equivalent SDH standard) equipment is expected to lower
the cost of long distance connections and, in combination with MFS' high
capacity local networks, enable the Company to provide a range of new Internet-
related services, including, over time, high quality voice and video
communications service. The pace of construction and number of connections
actually built will depend on a number of factors, including availability of
rights-of-way, market conditions, and the availability of certain high speed
SONET services from other carriers, which could serve as an alternative to the
construction of such connections. The Company currently leases certain medium
bandwidth long distance connections from other providers, the cost of which
represents a significant portion of the Company's network expense.
 
  Central Office Interconnection and Switch Deployment.  The Company plans to
interconnect at LEC central offices in all its metropolitan area networks and
plans to deploy approximately 25 additional switches over the 25 previously
planned. The Telecom Act mandates that incumbent LECs throughout the U.S. enter
into arrangements with competitors such as MFS for central office collocation
and unbundling of local services. The Company believes that implementing these
pro-competitive policies creates a unique opportunity to expand the Company's
offering of combined local and long distance services through interconnection
with local exchange carriers.
 
 Internet-Related Initiatives
 
  The Company believes the Internet is one of the most important developments
in the communications industry in decades. The recent rapid development of the
Internet, along with Internet-related technologies, products and services
(especially intranet applications), is expected to continue to stimulate
accelerated growth in demand for communications bandwidth. MFS believes IP
Packet switching will, over time, replace large portions of the circuit
switched voice network as the primary vehicle for business communications due
to the efficient use of bandwidth and the significantly lower transmission
costs associated with IP Packet switching. The amount of data transmitted over
the Internet backbone has grown very rapidly as a result of expanded Internet
use and the increasing complexity of information delivered via the Internet.
Currently, "Web pages" available on the Internet frequently include graphics
and, in some cases, sound and video, which require the transfer of more data to
the user's computer than do comparable text-only pages. See "Business--
Communications Industry Overview--Internet."
 
  MFS believes that availability of local loop bandwidth is the greatest
barrier to Internet development. The Company believes that its ability to
provide end-to-end high capacity bandwidth, unimpeded by a bottleneck at any
point along the path, uniquely positions it to provide superior business-
oriented Internet-related services.
 
  Given the Internet's rapid pace of growth, MFS believes that speed to market
will also be a major competitive advantage. On May 7, 1996, the Company
announced that it has undertaken several initiatives designed to augment its
Internet-related service offerings, including increasing and accelerating
network development and expansions, procurement of high-speed local loop
circuits, control of intercity high capacity fiber optic links discussed above
and, as announced on April 30, 1996, the Company's planned merger with UUNET.
 
  In the United States, the acceleration of central office interconnection
arrangements and the availability of unbundled local loops is expected to
enable the Company to offer a variety of higher
 
                                       7
<PAGE>
 
speed local Internet access services based on ISDN (Integrated Service Digital
Network) technology and, in the future, on such technologies as ADSL
(Asymmetric Digital Subscriber Loop) and HDSL (High Speed Digital Subscriber
Loop). In addition, the Company plans to significantly expand its existing
"Internet Hotel" space (that is, facilities space specifically created to allow
Internet service providers, Web page hosting service providers and others to
collocate with and utilize the network services of the Company).
Internationally, the Company intends to pursue a range of new Internet
initiatives similar to those planned for the United States as regulatory reform
and other factors allow, and to expand its "Internet Hotel" space and
international transport service in both Europe and Asia.
 
THE PROPOSED MERGER
 
  On April 29, 1996, the Company entered into the Merger Agreement with UUNET,
pursuant to which UUNET will become a wholly owned subsidiary of MFS (the
"Merger"). Pursuant to the Merger, each outstanding share of UUNET common stock
will be converted into and represent the right to receive 1.777776 shares (the
"Exchange Ratio") of the common stock, par value $.01 per share of MFS (the
"MFS Common Stock"). Consummation of the Merger is subject to various
conditions, including the approval of a majority of the outstanding shares of
the common stock, par value $.001 per share (the "UUNET Common Stock"), at a
special meeting of the stockholders of UUNET (the "UUNET Special Meeting") and
the approval by the affirmative vote of a majority of votes cast by the holders
of the outstanding shares of the capital stock of MFS at a meeting at which a
quorum is present. See "Description of the Merger."
 
  UUNET is a leading worldwide provider of a comprehensive range of Internet
access options, applications and consulting services to businesses,
professionals and on-line service providers. MFS believes that the Merger will
(i) allow the Company to expand its communications service offerings to include
UUNET's existing array of Internet-related services oriented toward the needs
of business and government customers, (ii) provide the Company with additional
technical expertise in configuring and managing complex, IP Packet switched
networks and (iii) over time, allow the Company to offer new services
(including voice and video communications services) utilizing UUNET's Internet
technology expertise and MFS' broadband, end-to-end networks. In addition, MFS
believes that the combined entity can, over time, improve profitability as a
result of (a) reduction in UUNET's "local loop" network costs (which UUNET
estimates to be approximately 40% of its "cost of revenues" in North America
for 1996) by utilizing available capacity on MFS' local networks, (b) receipt
of terminating access payments, or a reduction in cost of providing dial-up
Internet access, as mandated by the Telecom Act, (c) reduced cost of intercity
transport capacity purchased or leased from others as a result of increased
volume and migration of UUNET traffic to Company-owned facilities and (d)
incremental sales from offering UUNET services combined with MFS services to
the customers of UUNET. See "Risk Factors--Risk That Merger May Not Be
Consummated."
 
  Based on the number of shares of UUNET Common Stock outstanding at April 26,
1996, the Company expects to issue an aggregate of approximately 57.3 million
shares of MFS Common Stock in the Merger. Based on the closing price of the MFS
Common Stock on the day preceding the announcement of the Merger, the
stockholders of UUNET will receive shares of MFS Common Stock in the Merger
valued at approximately $2 billion.
   
  As a condition to entering into the Merger Agreement, MFS required certain
UUNET stockholders to enter into an agreement (as amended, the "Stock Option
Agreement") pursuant to which such stockholders agreed to vote their shares of
UUNET Common Stock in favor of the approval of the Merger Agreement and granted
irrevocable proxies in favor of MFS to vote all of such stockholders' shares of
UUNET Common Stock (equal to approximately 60% of the shares of UUNET Common
    
                                       8
<PAGE>
 
Stock). Accordingly, the proposal to adopt the Merger Agreement will be adopted
without the need of the vote of any other stockholders. As a condition to
entering into the Merger Agreement, UUNET required certain MFS directors owning
approximately 12% of the shares of MFS Common Stock prior to the Offerings, to
enter into an agreement (the "MFS Voting Agreement") pursuant to which such MFS
stockholders granted irrevocable proxies to vote all of such stockholders'
shares of MFS Common Stock in favor of the issuance (the "MFS Share Proposal")
of MFS Common Stock in connection with the Merger. See "Description of the
Merger."
 
  MFS and UUNET expect to consummate the Merger after the Offerings have been
completed as soon as the conditions to consummation of the Merger set forth in
the Merger Agreement have been satisfied. There can be no assurance that the
conditions to the consummation of the Merger will be satisfied and,
accordingly, that the Merger ultimately will be consummated. See "Risk
Factors--Risk That Merger May Not Be Consummated."

           CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS
 
  Certain statements contained in "Risk Factors," "Management's Discussion and
Analysis of Financial Condition and Results of Operations" and "Business,"
including statements regarding the development of the Company's businesses,
the markets for the Company's services and products, anticipated capital
expenditures, regulatory reform and the effects of the Merger, and other
statements contained herein regarding matters that are not historical facts,
are forward-looking statements (as such term is defined in the Private
Securities Litigation Reform Act of 1995). Because such statements include
risks and uncertainties, actual results may differ materially from those
expressed or implied by such forward-looking statements. Factors that could
cause actual results to differ materially include, but are not limited to,
those discussed under "Risk Factors."
 
                                 RISK FACTORS
 
  Prospective investors should consider carefully, together with the other
information contained in, or incorporated by reference into, this Prospectus,
the following factors:
 
OPERATING LOSSES
   
  A substantial portion of the expenditures relating to the development of the
Company's businesses, the installation and expansion of its domestic and
international networks and the recently proposed linking of these networks
through the acquisition or construction of facilities will be incurred before
the realization of revenues. These expenditures, together with the associated
up front operating expenses, result in negative cash flow until an adequate
customer base is established. MFS reported losses from operations of
approximately $31.5 million, $136.1 million and $239.3 million for the three
years ended December 31, 1993, 1994 and 1995, respectively, and $67.4 million
for the three months ended March 31, 1996. In addition, at March 31, 1996, the
Company had an accumulated deficit of approximately $727.3 million. Although
its revenues have increased substantially in each of the last three years and
for the three months ended March 31, 1996, MFS has incurred significant
increases in expenses associated with the development and expansion of its
fiber optic networks, services and customer base, which expenses are expected
to continue to grow for the foreseeable future. There can be no assurance that
MFS will achieve or sustain profitability.     
 
  The Merger will be treated as a purchase for accounting purposes and the
excess of the purchase price over the net book value of the net tangible
assets acquired will be recorded as goodwill and amortized over five years. As
a result, upon consummation of the Merger, there will be a substantial
increase in the amount of goodwill on the balance sheet of MFS, which will
result in substantially increased amortization charges. On a pro forma basis
for the Merger, MFS would have had an additional charge of approximately
$423.6 million relating to amortization for the year ended December 31, 1995.
As a result of these additional charges and operating losses currently being
generated by UUNET, if the Merger is consummated, MFS expects to continue to
report net losses for the foreseeable future.
 
SIGNIFICANT CAPITAL REQUIREMENTS
   
  The development of the Company's businesses, the installation and expansion
of its domestic and international networks and the recently proposed linking
of these networks through the acquisition or construction of facilities
require significant capital expenditures. During the first quarter of 1996,
MFS' capital expenditures, which are primarily for the construction of
networks and the purchase of related equipment, were approximately $153
million, including acquisitions and deferred costs. On May 7, 1996, MFS
announced that it intends to undertake certain initiatives designed to take
advantage of opportunities created by changes in telecommunications laws and
the rapid development of Internet technology-based communications networks.
These initiatives involve increasing the number of metropolitan areas served,
expanding its networks in existing metropolitan areas, constructing or
acquiring its own intercity high capacity network, accelerating central office
interconnection, deploying     
 
                                      13
<PAGE>
 
additional switches, providing high-speed local Internet access and, if the
Merger is consummated, implementing UUNET's plan to expand its international
presence and acquiring complementary businesses, technologies or products.
Expenditures for the initiatives are subject to MFS' review of a number of
factors including cost of any additional capital required, technological
developments and market conditions. In addition, each initiative may be
implemented in whole or in part, and independently of any other initiative,
ensuring that MFS retains maximum financial and operating flexibility.
 
  The Company anticipates that implementation of these initiatives, including
certain of the Internet-related initiatives, will, together with currently
anticipated expenditures, result in total average annual capital expenditures
of approximately $1.0 billion to $1.3 billion over the period of
implementation, which the Company expects to be up to four years. Since a
significant portion of the Company's capital expenditures are success-based
(that is, related directly to revenue growth), actual capital expenditures may
vary significantly from the above range depending on the level of incremental
sales. This range is also subject to a number of factors, including pace and
extent of network development, levels of incremental sales, as well as
regulatory actions by state, federal and international authorities, which,
individually or in the aggregate, could cause material changes in capital
expenditure requirements.
 
  The Company expects to fund its capital requirements through additional debt
or equity financing, existing resources and internally generated funds as
appropriate. There can be no assurance, however, that MFS will be successful
in producing sufficient cash flow or raising sufficient debt or equity capital
on terms that it will consider acceptable. Failure to generate or raise
sufficient funds may require the Company to delay or abandon some of its
future expansion or expenditures, which could have a material adverse effect
on the growth of the Company.
 
COMPETITION
 
 Traditional Telecommunications Services
 
  Virtually all markets for telecommunications services are extremely
competitive, and MFS expects that competition will intensify in the future. In
each of the markets in which it offers telecommunications services, MFS faces
significant competition from larger, better financed incumbent carriers. MFS
competes, both domestically and internationally, with incumbent providers,
which have historically dominated their local telecommunications markets, and
long distance carriers, for the provision of long distance services. In
certain markets, especially international markets, the incumbent provider
offers both local and long distance services. The incumbent LECs presently
have numerous advantages as a result of their historic monopoly control of the
local exchange market. A continuing trend toward business combinations and
alliances in the telecommunications industry may create significant new
competitors to MFS. Many of MFS' existing and potential competitors have
financial, personnel and other resources significantly greater than those of
MFS. MFS also faces competition in most markets in which it operates from one
or more competitors, including competitive access providers ("CAPs") operating
fiber optic networks, in some cases in conjunction with the local cable
television operator. Each of AT&T Corp. ("AT&T"), MCI Communications
Corporation ("MCI") and Sprint Corporation ("Sprint") has indicated its
intention to offer local telecommunications services in major U.S. markets
using its own facilities or by resale of the LECs' or other providers'
services. Other potential competitors include cable television companies,
wireless telephone companies, electric utilities, microwave carriers and
private networks of large end users. In addition, MFS competes with equipment
vendors and installers and telecommunications management companies with
respect to certain portions of its business.
 
  Under the Telecom Act and ensuing federal and state regulatory initiatives,
barriers to local exchange competition are being removed. The introduction of
such competition, however, also establishes the predicate for the Bell
Operating Companies (the "BOCs") to provide in-region interexchange long
distance services. The BOCs are currently allowed to offer certain
"incidental" long distance service in-region and to offer out-of-region long
distance services. Once the BOCs are allowed to offer in-region long distance
services, both they and the three largest long distance carriers (AT&T, MCI
and Sprint) will be in a position to offer single source local and long
distance service
 
                                      14
<PAGE>
 
similar to that being offered by MFS. The Company expects that the increased
competition made possible by regulatory reform will result in certain pricing
and margin pressures in the domestic telecommunications services business.
 
  MFS competes in three international markets: international services from the
United States; international services from certain countries in continental
Europe and Hong Kong; and domestic services within, and international services
from, the United Kingdom and Sweden. MFS offers private line, high-speed LAN
interconnect data and voice services in each of these markets, subject to
varying governmental authorizations. MFS faces competition in international
service originating in the United States from, among others, AT&T, MCI, Sprint
and WorldCom, Inc., which conducts business under the name "LDDS WorldCom"
("WorldCom"). These companies own significant international transmission
capacity and have established operating agreements with governmental and
private telecommunications providers in Europe, Asia and elsewhere, which
greatly reduce their cost of providing service. In international markets, MFS
competes with the incumbent telecommunications carrier, which generally offers
both local and long distance services and benefits from its status as an
incumbent provider.
 
 Internet-Related Services
 
  The market for data communications services, including Internet access and
on-line services, is extremely competitive. There are no substantial barriers
to entry, and the Company expects that competition will intensify in the
future. The Company believes that its ability to compete successfully depends
on a number of factors, including: market presence; the ability to execute a
rapid expansion strategy; the capacity, reliability and security of its
network infrastructure; ease of access to and navigation of the Internet; the
pricing policies of its competitors and suppliers; the timing of the
introduction of new products and services by the Company and its competitors;
the Company's ability to support industry standards; and industry and general
economic trends. The Company's success in this market will depend heavily upon
its ability to provide high quality Internet connectivity and value-added
Internet services at competitive prices. See "Business--Competition."
 
 Network Systems Integration Services
 
  MFS Network Technologies' primary network systems integration competitors
are the BOCs, long distance carriers, equipment manufacturers and major
independent telephone companies. In certain circumstances, MFS Network
Technologies may also compete with regional and local systems integration and
construction firms for integration and installation projects. In the automatic
vehicle identification market, MFS Network Technologies competes with specific
manufacturers and several of the aerospace defense contractors that have
indicated an intention to shift to commercial markets.
 
REGULATION
 
  MFS is subject to varying degrees of federal, state, local and international
regulation. In the United States, MFS is most heavily regulated by the states,
especially for the provision of local exchange services. MFS must be
separately certified in each state to offer local exchange and intrastate long
distance services. No state, however, subjects MFS to price cap or rate of
return regulation, nor is MFS currently required to obtain FCC authorization
for installation or operation of its network facilities used for domestic
services. FCC approval is required, however, for the installation and
operation of its international facilities and services. Both the states and
the FCC have determined that non-dominant carriers, such as MFS, are required
to file interstate tariffs on an ongoing basis, setting forth the carrier's
rates and operating procedures. Challenges to these tariffs by third parties
may cause MFS to incur substantial legal and administrative expenses. The FCC
has initiated a rulemaking to eliminate this requirement for all nondominant
carriers such as the Company. In addition, MFS is subject to varying degrees
of regulation in the foreign jurisdictions in which it conducts operations
including authorization for the installation and operation of its network
facilities. Although the trend in federal, state and international regulation
appears to favor increased competition, no assurance can be given that changes
in current or future regulations adopted by the FCC, state or foreign
regulators or
 
                                      15
<PAGE>
 
legislative initiatives in the United States and abroad would not have a
material adverse effect on MFS. See "Business--Government Regulation."
 
  Internet-related services are not currently subject to direct regulation by
the FCC or any other U.S. agency, other than regulation applicable to
businesses generally. The FCC recently requested comments on a petition filed
by the America's Carriers Telecommunication Association which requests that
the FCC regulate certain voice transmissions over the Internet as
telecommunications services. Changes in the regulatory environment relating to
the telecommunications or Internet-related services industry could have an
adverse effect on the Company's Internet-related services business. The
Telecom Act may permit telecommunications companies, BOCs or others to
increase the scope or reduce the cost of their Internet access services. The
Company cannot predict the effect that the Telecom Act or any future
legislation, regulation or regulatory changes may have on its business.
 
RISKS OF EXPANSION AND IMPLEMENTATION
 
  MFS is engaged in the expansion and development of its networks and
services. The expansion and development of its networks will depend on, among
other things, its ability to assess markets, design fiber optic network
backbone routes, install facilities and obtain rights-of-way, building access
and any required government authorizations and/or permits, all in a timely
manner, at reasonable costs and on satisfactory terms and conditions, as well
as its ability to expand, train and manage its growing employee base. Such
expansion has placed, and is expected to continue to place, significant
demands on MFS' management and operational and financial resources. As a
result, there can be no assurance that MFS will be able to expand its existing
networks or install new networks. If MFS is not able to expand its networks or
install or acquire new networks, there will be a material adverse effect on
its growth.
 
  Foreign operations or investment may be adversely affected by local
political and economic developments, exchange controls, currency fluctuations,
royalty and tax increases, retroactive tax claims, expropriation, import and
export regulations and other foreign laws or policies as well as by laws and
policies of the United States affecting foreign trade, taxation and
investment. In addition, in the event of a dispute arising from foreign
operations, MFS may be subject to the exclusive jurisdiction of foreign courts
or may not be successful in subjecting foreign persons to the jurisdiction of
courts in the United States. MFS may also be hindered or prevented from
enforcing its rights with respect to a governmental instrumentality because of
the doctrine of sovereign immunity.
 
  There can be no assurance that laws or administrative practice relating to
taxation, foreign exchange or other matters of countries within which the
Company operates or will operate will not change. Any such change could have a
material adverse effect on the Company's business, financial condition and
results of operations.
 
RAPID TECHNOLOGICAL CHANGES; DEPENDENCE UPON PRODUCT DEVELOPMENT
 
  The telecommunications industry is subject to rapid and significant changes
in technology. While MFS believes that, for the foreseeable future, these
changes will neither materially and adversely affect the continued use of
fiber optic cable nor materially hinder its ability to acquire necessary
technologies, the effect of technological changes, including changes relating
to emerging wireline and wireless transmission and switching technologies, on
the businesses of MFS cannot be predicted.
 
  The market for the Company's Internet-related products and services is
characterized by rapidly changing technology, evolving industry standards,
emerging competition and frequent new product and service introductions. There
can be no assurance that the Company will successfully identify new product
and service opportunities and develop and bring new products and services to
market in a timely manner. The Company is also at risk from fundamental
changes in the way Internet access services are marketed and delivered. The
Company's Internet service strategy assumes that the TCP/IP protocol,
utilizing fiber optic or copper-based telecommunications infrastructures, will
continue
 
                                      16
<PAGE>
 
to be the primary protocol and transport infrastructure for Internet-related
services. Emerging transport alternatives include cable modems and satellite
delivery of Internet information; alternative open protocol and proprietary
protocol standards have been or are being developed. The Company's pursuit of
necessary technological advances may require substantial time and expense, and
there can be no assurance that the Company will succeed in adapting its
Internet services business to alternate access devices, conduits and
protocols.
 
DEPENDENCE ON KEY PERSONNEL
 
  MFS' business is managed by a number of key executive officers, the loss of
certain of whom, particularly James Q. Crowe, the Company's Chairman of the
Board and Chief Executive Officer, could have a material adverse effect on the
Company. MFS believes that its future success will depend in large part on its
continued ability to attract and retain highly skilled and qualified
personnel. MFS does not have employment agreements with any of its key
executive officers.
 
RISK THAT MERGER MAY NOT BE CONSUMMATED
 
  The consummation of the Merger is subject to a number of conditions,
including but not limited to (i) the approval by the UUNET stockholders of the
Merger, (ii) the approval by the MFS stockholders of the MFS Share Proposal,
(iii) the absence of any preliminary or permanent injunction or other order by
any federal or state court in the United States which prevents the
consummation of the Merger, (iv) the performance by each party to the Merger
Agreement in all material respects of all of its obligations in the Merger
Agreement, (v) the representations and warranties of each party in the Merger
Agreement being true and correct in all material respects, and (vi) the
receipt of certain specified third party consents. In the event one or more of
the conditions is not satisfied, the Merger may be delayed or the Merger
Agreement may be terminated. In addition, under certain other circumstances,
the Merger Agreement may be terminated by either MFS or UUNET, and may be
terminated at any time by mutual consent of the Boards of Directors of MFS and
UUNET. There can be no assurance that the conditions to consummation of the
Merger will be satisfied, that the Merger will not be delayed or that the
Merger Agreement will not be terminated in accordance with its terms. See
"Description of the Merger."
 
INTEGRATION OF MFS AND UUNET
 
  MFS believes that the Merger will result in certain benefits. Achieving
these benefits will depend in part upon the integration of the businesses of
UUNET and MFS in an efficient manner, and there can be no assurance that this
will occur. The transition to a combined company will require substantial
attention from management. Neither company's management has experience in
integrating operations on the scale represented by the Merger. The diversion
of management attention and any difficulties encountered in the transition
process could have an adverse effect on the revenues and operating results of
the Company. In addition, there can be no assurance that management of the two
companies will be compatible and the process of combining the two
organizations could cause the interruption of, or a disruption in, the
activities of either or both of the companies' businesses, which could have an
adverse effect on their combined operations. There can be no assurance that
the Company will realize any of the anticipated benefits of the Merger.
 
ACQUISITION STRATEGY
   
  Both MFS and UUNET have acquired complementary businesses as part of their
business strategies. UUNET is in the process of integrating certain of the
operations, research and development, sales and marketing, finance and
administrative functions of Unipalm Group plc (doing business under the name
"UUNET PIPEX") ("UUNET PIPEX") and UUNET Canada, Inc. ("UUNET Canada"). In
addition, UUNET has recently acquired 40% of the equity ownership of EUnet
Deutschland GmbH ("EUnet Germany").     
 
                                      17
<PAGE>
 
  After the Merger, it is likely that MFS will continue to acquire
complementary businesses, and any future acquisitions will be accompanied by
the risks commonly associated with acquisitions. These risks include potential
exposure to unknown liabilities of acquired companies or to acquisition costs
and expenses, the difficulty and expense of integrating the operations and
personnel of the companies, the potential disruption to the business of the
Company and potential diversion of management time and attention, the
impairment of relationships with and the possible loss of key employees and
customers as a result of changes in management, incurring amortization
expenses if an acquisition is accounted for as a purchase and dilution to the
stockholders of the Company if the acquisition is made for stock of the
Company. There can be no assurance that products, technologies or businesses
of acquired companies will be effectively assimilated into the business or
product offerings of the Company. In addition, the Company may incur
significant expense to complete acquisitions and to support the acquired
products and businesses. There can be no assurance that any acquired products,
technologies or businesses will contribute to the Company's revenues or
earnings to any material extent. Further, the challenge of managing the
integration of future acquisitions may distract management and may interfere
with the successful integration of MFS and UUNET.
 
POTENTIAL LIABILITY OF ON-LINE SERVICE PROVIDERS
   
  The law in the United States relating to the liability of on-line services
providers and Internet access providers for information carried on,
disseminated through or hosted on their systems is currently unsettled.
Several private lawsuits seeking to impose such liability are currently
pending. In one case brought against an Internet access provider, Religious
Technology Center v. Netcom On-Line Communication Services, Inc., the United
States District Court for the Northern District of California ruled in a
preliminary phase that under certain circumstances Internet access providers
could be held liable for copyright infringement. The case has not reached
final judgment. The Telecom Act prohibits and imposes criminal penalties and
civil liability for using an interactive computer service for transmitting
certain types of information and content, such as indecent or obscene
communications. On June 12, 1996, however, a panel of three federal judges
granted a preliminary injunction barring enforcement of this portion of the
Telecom Act to the extent that enforcement is based upon allegations other
than obscenity or child pornography as an impermissible restriction on the
First Amendment's right of free speech. In addition, numerous states have
adopted or are currently considering similar types of legislation. The
imposition upon Internet access providers or Web hosting sites of potential
liability for materials carried on or disseminated through their systems could
require the Company to implement measures to reduce its exposure to such
liability, which may require the expenditure of substantial resources or the
discontinuation of certain product or service offerings. The Company believes
that it is currently unsettled whether the Telecom Act prohibits and imposes
liability for any services provided by the Company should the content or
information transmitted be subject to the statute.     
 
  The law relating to the liability of on-line service providers and Internet
access providers in relation to information carried, disseminated or hosted
also is being developed in the United Kingdom and other jurisdictions. The
scope of authority of various regulatory bodies in relation to on-line
services is at present uncertain. The Office of Telecommunications in the
United Kingdom has recently published a consultative document setting out a
number of issues for discussion, including the roles of traditional
telecommunications and broadcasting regulators with respect to on-line
services. The Securities Investment Board is investigating the status of on-
line services and the transmission of investment information over networks
controlled by access providers. Such transmissions may make an access provider
liable for any violation of securities and other financial services
legislation and regulations. Decisions regarding regulation, enforcement,
content liability and the availability of Internet access in other countries
may significantly affect the ability to offer certain services worldwide and
the development and profitability of companies offering Internet and on-line
services in the future. For example, CompuServe Corporation recently removed
certain content from its services worldwide in
 
                                      18
<PAGE>
 
reaction to law enforcement activities in Germany, and it has been reported
that an Internet access provider in Germany has been advised by prosecutors
that it may have liability for disseminating neo-Nazi writings by providing
access to the Internet where these materials are available.
 
  The increased attention focused upon liability issues as a result of these
lawsuits, legislation and legislative proposals could affect the growth of
Internet use. While UUNET has insurance and MFS intends to continue such
insurance coverage if the Merger is consummated, it may not be adequate to
compensate the Company in the event UUNET becomes liable for information
carried on or disseminated through its systems. Any costs not covered by
insurance incurred as a result of such liability or asserted liability could
have a material adverse effect on the Company's business, financial condition
and results of operations.
 
DEPENDENCE UPON NETWORK INFRASTRUCTURE; RISK OF SYSTEM FAILURE; SECURITY RISKS
 
  MFS' success in marketing its services to business and government users
requires that the Company provide superior reliability, capacity and security
via its network infrastructure. The Company's networks are subject to physical
damage, power loss, capacity limitations, software defects, breaches of
security (by computer virus, break-ins or otherwise) and other factors,
certain of which have caused, and will continue to cause, interruptions in
service or reduced capacity for MFS customers. Similarly, UUNET's business
relies on the availability of its network infrastructure for the provision of
Internet access services. Interruptions in service, capacity limitations or
security breaches could have a material adverse effect on the Company's
business, financial condition and results of operations.
 
VARIABILITY OF QUARTERLY OPERATING RESULTS
 
  As a result of the significant expenses associated with the expansion and
development of its networks and services, MFS anticipates that its operating
results could vary significantly from period to period and such variability
could adversely affect MFS' results of operations. Additional factors
contributing to variability of operating results include the pricing and mix
of services and products sold by the Company, customer terminations of
service, the timing of the expansion of the Company's network infrastructure
domestically and internationally, the timing and costs of marketing and
advertising efforts, and the timing and costs of any acquisitions of
businesses, products or technologies. In addition, MFS' network systems
integration revenues are, and generally will continue to be, dependent upon a
small number of large projects. Accordingly, these revenues are likely to vary
significantly from period to period, and such variability could adversely
affect MFS' results of operations.
 
STRATEGIC RELATIONSHIP BETWEEN UUNET AND MICROSOFT
 
  In December 1994, UUNET and Microsoft Corporation ("Microsoft") entered into
a strategic relationship for the development, operation and maintenance of a
large-scale high speed dial-up and ISDN TCP/IP access network which is the
primary Internet dial-up network and infrastructure for Microsoft, including
The Microsoft Network. The parties entered into a TCP/IP Local Access Network
Agreement (the "Microsoft Agreement") and a loan agreement under which
Microsoft agreed to lend UUNET up to $26.0 million to cover the anticipated
capital cost of the network equipment. Revenues from Microsoft totaled
approximately 20% and 37% of UUNET's consolidated revenues during the year
ended December 31, 1995 and the quarter ended March 31, 1996, respectively.
The Company expects that UUNET will continue to derive a significant portion
of its revenues from Microsoft for at least the next several years, and the
Microsoft Agreement limits UUNET's ability to enter into similar agreements
for the development of other large-scale dial-up networks prior to March 1997.
Although UUNET has met Microsoft's needs through March 31, 1996, there can be
no assurance that the
 
                                      19
<PAGE>
 
Company will be able to meet all future deployment commitments to Microsoft
after the Merger. After September 1996, Microsoft may terminate the Microsoft
Agreement if UUNET breaches certain material terms of the Microsoft Agreement
and is unable to cure, thereby causing a sustained operational failure of the
dial-up network. Termination of the Microsoft Agreement by Microsoft for any
reason could result in the loss of all future revenues from Microsoft and the
acceleration of UUNET's obligation to pay to Microsoft amounts due under the
loan agreement. Any such termination, loss or acceleration or imposition of
penalties would have a materially adverse effect on UUNET's business. In
addition, any regulatory or private party legal challenges to The Microsoft
Network, including those in the United States and Europe which have been
threatened to date, could result in termination or restructuring of the
strategic relationship with Microsoft, which would have a material adverse
effect on the Company. The terms of construction, maintenance and operation
(including the allocation of costs and payment of fees) of international
gateway hubs beyond the initial 14 such hubs are subject to future agreement
between Microsoft and UUNET. UUNET expects that the terms of any funding or
revenues from Microsoft relating to additional international hubs, if any,
will be different from those of the Microsoft Agreement. In addition, UUNET
and Microsoft have an understanding that providers of Internet access services
(such as Post, Telephone and Telegraph Administrations ("PTTs")) will begin to
bear certain of the costs of the 14 international gateway hubs. As this
begins, Microsoft's share of such costs will decrease, and UUNET will become
more dependent upon such providers and their customers for revenues to support
such costs. Microsoft continues to evolve its international strategy for The
Microsoft Network, and its final strategy may differ materially from that
originally anticipated. Although UUNET is Microsoft's primary Internet access
provider, there can be no assurance that Microsoft will obtain additional
Internet network infrastructure or capacity it may require from UUNET, other
than that specified in the Microsoft Agreement. Microsoft has announced a
relationship with MCI under which MCI will resell The Microsoft Network,
Microsoft's Internet Explorer Web browser software and other Microsoft
Internet-related software. Although the terms of the relationship have not
been fully disclosed, this relationship with MCI may allow access to The
Microsoft Network through MCI's dial-up network. Further, Microsoft is
developing relationships with other Internet service providers to resell The
Microsoft Network and the Internet Explorer. As originally planned, Microsoft
is developing relationships with foreign and domestic telecommunications
companies and Internet access providers to resell access to The Microsoft
Network. If Microsoft fully develops these resale relationships, the Company's
revenues may not receive revenues from Microsoft beyond Microsoft's guaranteed
minimum payments. Any failure of such revenues to increase could have a
material adverse effect on UUNET's business, financial condition or results of
operations. See "Business--Internet-Related Services--Microsoft Relationship."
 
UUNET'S DEPENDENCE UPON SUPPLIERS; SOLE AND LIMITED SOURCES OF SUPPLY
 
  UUNET relies on other companies to supply certain key components of its
network infrastructure, including telecommunications services and networking
equipment, which, in the quantities and quality demanded by UUNET, are
available only from sole or limited sources. UUNET is also dependent upon LECs
to provide telecommunications services to UUNET and its customers. UUNET has
from time to time experienced delays in receiving telecommunications services,
and there can be no assurance that UUNET will be able to obtain such services
on the scale and within the time frames required by UUNET at an affordable
cost, or at all. Any failure to obtain such services or additional capacity on
a timely basis at an affordable cost, or at all, would have a material adverse
effect on UUNET's business, financial condition and results of operations.
UUNET also is dependent on its suppliers' ability to provide necessary
products and components that comply with various Internet and
telecommunications standards, interoperate with products and components from
other vendors and function as intended when installed as part of the network
infrastructure. Any failure of UUNET's sole or limited source suppliers to
provide products or components that comply with Internet standards,
interoperate with other products or components used by UUNET in its network
infrastructure or by its customers or fulfill their intended function as a
part of the network infrastructure could have a material adverse effect on
 
                                      20

UUNET's business, financial condition and results of operations. See
"Business--Internet-Related Services."
 
TAX NET OPERATING LOSS CARRYFORWARDS
 
  As of December 31, 1995, MFS and UUNET had federal income tax net operating
loss carryforwards ("NOLs") of approximately $420 million and $12 million,
respectively, which expire primarily in years beginning in 2008.
   
  MFS believes that the Merger will cause an "ownership change" within the
meaning of Section 382 of the Internal Revenue Code of 1986, as amended (the
"Code") with respect to both MFS and UUNET. Consequently, MFS' and UUNET's NOL
and credit carryovers from periods prior to the Merger will be subject to
annual limitations. Under Section 382, a corporation is only allowed to use a
portion of its NOL and credit carryovers from periods prior to an ownership
change to offset its income in periods subsequent to the ownership change.
This yearly limitation (the "Section 382 limitation") is generally equal to
the value of all of the outstanding stock of the corporation immediately prior
to the ownership change multiplied by the "applicable long-term tax-exempt
rate," which is the highest of the adjusted federal long-term rates in effect
for any month in the three calendar month period ending with the calendar
month in which the ownership change date occurs.     
   
  In general, MFS will be required to pay federal income tax in any year in
which its taxable income exceeds the amount of each of the Section 382
limitation plus any NOL and credit carryovers from years subsequent to the
ownership change. To the extent the Company does not use the full amount of
its Section 382 limitation in any year, such unused portion can be used to
increase the Section 382 limitation for subsequent years. Based on the value
of MFS and UUNET prior to the Merger, the amount of the NOLs of each company
prior to the Merger and the fact that MFS expects to have significant NOLs in
1996 and 1997, MFS believes that the Section 382 limitations will not have a
material effect on the amount of its federal income tax liability in future
years.     
 
ANTI-TAKEOVER PROVISIONS IN MFS' CHARTER AND BY-LAWS
   
  MFS' Restated Certificate of Incorporation and By-laws contain provisions
that could delay, defer or prevent a change in control without the approval of
its incumbent Board of Directors. These provisions, among other things, (i)
divide the MFS Board of Directors into three classes, with members of each
class to be elected in staggered three-year terms, (ii) prohibit stockholder
action by written consent in lieu of a meeting, (iii) limit the right to call
special meetings of stockholders and (iv) authorize the MFS Board of Directors
to issue preferred stock in one or more classes or series without any action
on the part of stockholders. Such provisions could limit the price that
investors might be willing to pay in the future for shares of MFS Common Stock
and significantly impede the ability of the holders of MFS Common Stock to
replace management. In addition, MFS has adopted a Rights Agreement, dated as
of September 30, 1995, between MFS and Continental Stock Transfer & Trust
Company (the "MFS Rights Plan"), which has certain anti-takeover effects. The
MFS Rights Plan will cause substantial dilution to a person or group that
attempts to acquire MFS on terms not approved by MFS' Board of Directors.
Provisions and agreements that inhibit or discourage takeover attempts could
reduce the market value of the MFS Common Stock. See "Description of MFS
Capital Stock."     
   
  MFS has outstanding 15,000,000 shares of Series B Convertible Preferred
Stock (the "Series B Preferred Stock"). Each share of Series B Preferred Stock
is entitled to 10 votes with respect to any and all matters presented to the
MFS stockholders for their action and consideration. The Series B Preferred
Stock is presently convertible into approximately 695,652 shares of MFS Common
Stock. As a result of the special voting rights associated with the Series B
Preferred Stock, the holders of such shares (which would represent
approximately 0.5% of the shares of MFS Common Stock assuming     
 
                                      21
<PAGE>
 
conversion of such shares) will have the right to exercise approximately 47%
of the voting power of the Company immediately after the Offerings (and
approximately 40% of the voting power of the Company immediately after the
consummation of the Offerings and the Merger). The shares of Series B
Preferred Stock, however, are held subject to an irrevocable proxy that has
been granted to the Secretary and Assistant Secretary of MFS to vote all
shares of Series B Preferred Stock on all matters, other than the election of
directors and matters as to which the holders of Series B Preferred Stock vote
as a separate class, in proportion to the vote of holders of MFS Common Stock.
The non-transferability of the shares of Series B Preferred Stock, as well as
the special voting rights of such shares, may deter or discourage takeover
attempts. See "Description of MFS Capital Stock."
 
SHARES ELIGIBLE FOR FUTURE SALE
 
  Sales of substantial numbers of shares of MFS Common Stock in the public
market following the Offerings could adversely affect the market price of the
Shares. In connection with the Merger, the Company has filed a registration
statement on Form S-4 with the Commission relating to up to approximately 57.3
million shares of Common Stock to be issued to stockholders of UUNET (the
"Merger Shares"), which shares will represent approximately 27% of the issued
and outstanding shares of MFS Common Stock after giving effect to the
Offerings. In connection with the Merger, following consummation of the
Merger, the Company will file with the Commission a registration statement on
Form S-8 covering approximately 5.7 million shares of MFS Common Stock which
will be issuable to holders of options to acquire UUNET Common Stock upon the
exercise of such options. Except for the Merger Shares acquired by affiliates
of UUNET, all of the Merger Shares will be freely tradable following
consummation of the Merger. Shares held by affiliates of UUNET will be
eligible for resale in accordance with the provisions of Rule 145 under the
Securities Act. Sales by affiliates under Rule 145 are subject to the volume
limitations under Rule 144 as well as certain other limitations under the
Securities Act (which generally limit sales by the affiliate during any 90-day
period to the greater of 1% of the outstanding shares or the average weekly
trading volume during the four calendar weeks preceding the sale). In the
event UUNET stockholders elect to sell a substantial number of the Merger
Shares following consummation of the Offerings, the market price of the Shares
could be adversely affected.
 
SUBSTANTIAL DILUTION
 
  As a result of the Offerings, persons purchasing Shares in the Offerings
will experience an immediate dilution in net tangible book value per share of
MFS Common Stock. See "Dilution." In addition, the Merger will cause a
reduction in the net tangible book value of the shares of MFS Common Stock
purchased in the Offerings.
 
                                      22
<PAGE>
 
                                USE OF PROCEEDS
   
  The net proceeds from the Offerings are estimated to be $975.8 million
($1,122.4 million if the Underwriters' over-allotment options are exercised in
full) at an assumed Price to Public of $36.00. The Company intends to use
substantially all of the net proceeds from the Offerings to fund the initial
capital expenditures related to the initiatives announced by the Company on
May 7, 1996, including the expansion of the Company's International Network
Platform and its Internet-related businesses. The Company does not expect that
its capital requirements will change materially if the Merger is not
consummated.     
   
  The initiatives announced by the Company on May 7, 1996 consist of (i)
accelerating interconnection of MFS' networks at all LEC Central Offices in
MFS' metropolitan network locations, (ii) deploying 50, up from 25, local
switches, (iii) increasing the number of U.S. metropolitan areas served from
65 to 85, (iv) increasing the number of international financial centers served
from 25 to 45, (v) expanding 35 of the Company's existing metropolitan
networks, (vi) constructing or acquiring high capacity intercity optical fiber
links, both domestically and internationally and submarine optical fiber
links, (vii) offering Internet protocol dedicated trunk circuits to private
Intranet networks and (viii) providing local Internet access.     
   
  The Company currently estimates that initial capital expenditures, in the
aggregate, for all of the Company's May 7th initiatives will approximate $1.3
billion. Of that amount, approximately 15% to 20% will be used to construct or
acquire domestic intercity optical fiber links and approximately 30% will be
used to construct or acquire international intercity and submarine optical
fiber links. The remaining seven initiatives enumerated above would each
require between $50 million to $150 million in initial capital expenditures.
Each of these initiatives may be implemented in whole or in part, and
independently of any other initiative, thereby ensuring that the Company
retains maximum financial and operating flexibility.     
   
  The Company anticipates that implementation of its May 7th initiatives
including certain of the Internet-related initiatives will, together with
currently anticipated expenditures, result in total average annual capital
expenditures of approximately $1.0 billion to $1.3 billion over the period of
implementation, which the Company expects to be up to four years. Since a
significant portion of the Company's capital expenditures are success-based
(that is, related directly to revenue growth), actual capital expenditures,
including the allocation of the net proceeds from the Offerings related to the
May 7th initiatives, may vary significantly from the above range depending on
the level of incremental sales. This range of the level of capital
expenditures, and the allocation of the net proceeds from the Offerings are
also subject to a number of factors, including technological developments,
levels of incremental sales and the pace of implementation, as well as
regulatory actions by state, federal and international authorities, which
individually or in the aggregate, could cause material changes in capital
expenditure requirements. To the extent that the Company does not use the net
proceeds from the Offerings to fund the initial capital expenditures related
to the May 7th initiatives, the Company will use the net proceeds for general
corporate purposes, consistent with its general corporate strategy and its May
7th initiatives.     
          
  The Company estimates that the sources for the remaining capital required to
implement the May 7th initiatives include existing resources, internally
generated funds and additional debt or equity financing as appropriate. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Liquidity and Capital Resources."     
 
  If the Merger is terminated by UUNET because of the failure of MFS to meet
certain closing conditions, or if the MFS stockholders do not approve the MFS
Share Proposal, MFS will use a portion of the proceeds to pay UUNET a penalty
of $60.0 million and, at UUNET's option, to purchase 1,551,724 shares of UUNET
Common Stock at an aggregate cost of $90.0 million. See "Description of the
Merger--Termination; Fees and Expenses."
 
                                      23
<PAGE>
 
  The Company intends to continue to pursue its expansion plans aggressively.
Consistent with its past experience, the Company expects that a significant
portion of its expansion may occur through acquisitions. The consideration for
any acquisition could consist of securities (including shares of MFS Common
Stock), cash or any combination thereof. The Company may acquire public or
private companies and, under appropriate circumstances, may consider the
acquisition of public companies on an unsolicited basis. Except for the
Merger, the Company has no agreement, agreement in principle, understanding or
arrangement with any person to acquire or effect any material acquisition.
 
  Pending application as described above, the net proceeds to the Company will
be invested in short-term, investment grade securities.

                                   DILUTION
 
  At March 31, 1996, the historical net tangible book value of the Company was
$350 million or $2.79 per share of Common Stock. "Historical net tangible book
value per share" represents the Company's net worth less intangible assets of
$405 million divided by 125.6 million shares of MFS Common Stock outstanding
on March 31, 1996. After giving effect to the sale by the Company of 28
million Shares pursuant to the Offerings at an assumed Price to Public of
$36.00 per share and after deducting the underwriting discount and expenses of
the Offerings, the pro forma net tangible book value of the Company at March
31, 1996, would have been $1,326 million, or $8.63 per share of MFS Common
Stock. Such amount represents an immediate increase in pro forma net tangible
book value of $5.84 per share of MFS Common Stock to the existing stockholders
and an immediate dilution to new investors of $27.37 per share of MFS Common
Stock. Purchasers of MFS Common Stock in the Offerings will experience
additional dilution in net tangible book value per share as a result of the
Merger. On a pro forma basis for the Offerings and the Merger at March 31,
1996, and assuming the issuance of approximately 57.3 million shares of MFS
Common Stock in the Merger, the pro forma net tangible book value of MFS
Common Stock after the Offerings and the Merger would have been $6.61 per
share. The following table illustrates the dilution in pro forma net tangible
book value per share to new investors:

  The foregoing table assumes no exercise of the Underwriters' over-allotment
options to purchase an additional 4,200,000 shares at the Price to Public less
the underwriting discount, and further assumes no exercise of outstanding
options and warrants to acquire additional shares of MFS Common Stock or
conversion of convertible securities. To the extent such options and warrants
are exercised or convertible securities are converted, purchasers of MFS
Common Stock in the Offerings may experience additional dilution in net
tangible book value per share.

                                DIVIDEND POLICY
 
  The Company has not paid any cash dividends on its capital stock. The
Company intends to retain future earnings, if any, to finance the development
and expansion of its businesses and, therefore, does not anticipate paying any
cash dividends in the foreseeable future on its capital stock. The decision
whether to pay cash dividends will be made by the Board of Directors in light
of conditions then existing, including the Company's results of operations,
financial condition and requirements, business conditions and other factors.
Because the Company's principal assets are its investments in the equity
securities of its subsidiaries, its cash flow and consequent ability to pay
cash dividends will be dependent on the earnings of its subsidiaries, the
distribution of those earnings to the Company and other business
considerations of the subsidiaries. In addition, certain agreements to which
the Company is a party limit the payment of dividends or other distributions
on any capital stock of the Company.
 
  During 1995, the Company issued depositary shares, each representing a one
one-hundredth interest in a share of Series A 8% Cumulative Convertible
Preferred Stock, par value $.01 per share (the "Series A Preferred Stock").
Holders of shares of Series A Preferred Stock are entitled to receive
dividends, when, as and if they are declared by the Board of Directors,
accruing at the rate of $2.68 per share per annum, payable quarterly in
arrears on each February 28, May 31, August 31 and November 30. Dividends are
payable in cash or in shares of MFS Common Stock, at the election of the
Company. Certain of the Company's debt agreements restrict the Company's
ability to pay cash dividends, and as a result, the Company does not
anticipate that it will pay cash dividends on the Series A Preferred Stock for
the foreseeable future. The Company paid the dividend on August 31 and
November 30, 1995 and February 28, 1996 in shares of MFS Common Stock and has
announced that it will pay the May 31, 1996 dividend in shares of MFS Common
Stock.
 
  Also during 1995, the Company issued the Series B Preferred Stock. Dividends
on the Series B Preferred Stock accrue at the rate of 7 3/4% per annum and are
payable in cash. Dividends will be paid only when, as and if declared by the
Board of Directors of the Company. Certain of the Company's debt agreements
restrict the Company's ability to pay cash dividends, and as a result, the
Company anticipates that dividends on the Series B Preferred Stock will not be
declared but will continue to accrue. Upon conversion, accrued but unpaid
dividends are payable in cash or shares of MFS Common Stock at the Company's
election.

                     SELECTED CONSOLIDATED FINANCIAL DATA
 
  The selected consolidated financial data for each of the years in the period
1991 to 1995 have been derived from audited historical consolidated financial
statements. The selected consolidated financial data as of and for the three
months ended March 31, 1996 and 1995, have been derived from unaudited
consolidated financial statements of the Company. In the opinion of
management, the unaudited financial statements have been prepared on the same
basis as the MFS Consolidated Financial Statements and include all
adjustments, which consist only of normal recurring adjustments, necessary for
a fair presentation of the financial position and the results of operations
for these periods. Operating results for the three months ended March 31, 1996
are not necessarily indicative of the results that may be expected for the
full year. The development and acquisition by the Company of its networks and
services during the periods reflected materially affect the comparability of
that data from one period to another. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations." The following
selected consolidated data should be read in conjunction with the MFS
Consolidated Financial Statements and the notes thereto incorporated by
reference and included herein.

               MFS COMMUNICATIONS COMPANY, INC. AND SUBSIDIARIES
 
        NOTES TO PRO FORMA CONSOLIDATED CONDENSED FINANCIAL STATEMENTS
            (DOLLARS IN THOUSANDS EXCEPT PER SHARE DATA-UNAUDITED)
 
NOTE 1: PRO FORMA STATEMENTS
 
  The pro forma information as of, and for the three months ended March 31,
1996 is based on unaudited financial statements of MFS and UUNET after giving
effect to the preliminary allocation of the purchase price and the adjustments
described in Note 2.
 
  The pro forma information for the year ended December 31, 1995 is based on
historical financial statements of MFS and UUNET after giving effect to the
adjustments described in Note 2.
 
  The unaudited pro forma consolidated condensed financial statements may not
be indicative of the results that actually would have been achieved if the
acquisition had occurred on the dates assumed and do not project MFS'
financial position or results of operations at any future date or period then
ended.
 
NOTE 2: PRO FORMA ADJUSTMENTS
 
(1)  Reflects the excess of the purchase price over the net book value (which
     approximates fair value) of the net tangible assets acquired which was
     recorded as goodwill, a customer contract and customer list. The pro
     forma adjustment to depreciation and amortization represents the
     amortization of the goodwill and other intangibles and was calculated
     using the straight-line method over a five year life for goodwill and
     three to four year lives for the other intangibles.
(2) Reflects liabilities incurred, such as compensation costs and legal,
    accounting and consulting fees related to the Merger.
(3)Reflects the elimination of the equity accounts of UUNET.
(4)Reflects the elimination of intercompany revenues and expenses.
(5)Reflects adjustment of federal income tax expense for the effects of the
Merger.
(6) Reflects the effect of the issuance of MFS Common Stock and options to
    purchase MFS Common Stock in connection with the Merger. The MFS Common
    Stock was valued at $34.69 per share for purposes of calculating the
    Merger consideration.
 
NOTE 3: OTHER MATTERS
   
  If the Merger Agreement is not approved, the Company may exercise the option
to purchase shares of UUNET Common Stock representing approximately 60% of the
UUNET Common Stock from certain holders of UUNET Common Stock. Should the
Company exercise the Option, the pro forma consolidated condensed statement of
operations for the year ended December 31, 1995 would include depreciation and
amortization of $400,211 (rather than $574,446), loss from operations of
$(509,241) (rather than $(683,476)), other income of $4,236 (rather than other
expense of $(2,702)), loss before income taxes of $(528,484) (rather than
$(709,657)), net loss of $(529,084) (rather than $(710,257)), loss applicable
to common stockholders of $(544,148) (rather than $(725,321)), weighted
average number of shares outstanding of 163,280,000 (rather than 185,034,000)
and pro forma net loss per share applicable to common stockholders of $(3.33)
(rather than $(3.92)). In addition, the pro forma consolidated condensed
statement of operations for the three months ended March 31, 1996 would
include depreciation and amortization of $110,905 (rather than $154,464), loss
from operations of $(129,335) (rather than $(172,894)), other expense of
$(1,259) (rather than $(1,170)), loss before income taxes of $(148,328)
(rather than $(191,798)), net loss of $(148,428) (rather than $(191,898)),
loss applicable to common stockholders of $(155,500) (rather than $(198,970)),
weighted average     
 
                                      34

number of shares outstanding of 160,511,000 (rather than 182,265,000) and pro
forma net loss per share applicable to common stockholders of $(0.97) (rather
than $(1.09)). The pro forma consolidated condensed balance sheet at March 31,
1996, would include goodwill of $1,390,805 (rather than $2,178,445), other
assets of $214,901 (rather than $266,391), MFS Common Stock of $1,610 (rather
than $1,828) and additional paid-in capital of $2,713,258 (rather than
$3,583,362).     
 
  Under certain conditions, which include the failure of MFS Stockholders to
approve the Merger, the Company may be required to pay a penalty of $60,000
and at UUNET's option, be required to purchase 1,551,724 shares of newly
issued UUNET Common Stock for $90,000, and, at UUNET's option, to provide a
maximum of $100,000 of certain data communications services to UUNET at MFS'
cost for five years. Should the Company be required to pay the penalty and
purchase the shares of newly issued UUNET Common Stock, the pro forma
consolidated condensed balance sheet at March 31, 1996, would include an
investment of $90,000 (subject to valuation at fair value), MFS Common Stock
of $1,255 (rather than $1,828), additional paid-in capital of $1,482,442
(rather than $3,583,362) and an increase in accumulated deficit of $60,000.

  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
                                  OPERATIONS
 
OVERVIEW
 
  The Company was founded in 1987 and commenced operations in 1988. The
Company operates through its subsidiaries in two business segments,
telecommunications services and network systems integration. The
telecommunications segment is comprised of the MFS Telecom Companies, which
provide services to large customers through MFS Telecom and MFS Datanet, the
MFS Intelenet Companies, which provide services to small and medium sized
customers through MFS Intelenet, MFS International, which provides services to
customers internationally and Global Network Services, which manages the
Company's network platform. The network systems integration segment provides
services primarily through MFS Network Technologies. Through December 31,
1995, the Company's growth, including its capital expenditure requirements,
acquisition financing and working capital, has been funded by two common stock
offerings in 1993, the offering of 9 3/8% Senior Discount Notes (the "1994
Senior Discount Notes") in 1994, a preferred stock offering in 1995 and, prior
to 1993, by capital contributions by Kiewit Diversified Group Inc., the
Company's former majority stockholder ("KDG"). In January 1996, the Company
issued 8 7/8% Senior Discount Notes (the "1996 Senior Discount Notes").
 
  Telecommunications Services
 
  The Company's telecommunications services predominately result in monthly
recurring revenues. The Company provides these services in an expanding number
of major metropolitan areas. As of February 1996, the Company provides
services on its networks, or through the resale of services, or has network
operations under development in 52 major metropolitan areas in the United
States, Europe and Asia.
 
  The development of the Company's businesses and the installation and
expansion of its networks require significant expenditures, a substantial
portion of which is incurred before the realization of revenues. These
expenditures, together with the associated early operating expenses, result in
negative cash flow until an adequate customer base is established. As this
customer base grows, incremental revenues are added with minimal additional
expense, providing significant contributions to cash flow. The Company also
incurs ongoing capital expenditures with respect to both existing and new
networks which are directly related to the installation of new revenue
producing circuits. These costs vary based on the specific type of circuit
installed and the location of the customer.
 
  The MFS Telecom Companies. Through MFS Telecom, the Company provides
dedicated special access and private line service to business and government
end users. These services are provided primarily over digital fiber optic
telecommunications networks that the Company has either installed or acquired
and subsequently expanded. The networks also establish a platform that can be
used to provide additional enhanced voice, data and video services to its
customers. MFS Telecom also offers local switched services to its customers in
New York utilizing the Company's integrated switching platform.
 
  Through MFS Datanet, the Company provides high-speed data communications
services to business and government users over an international ATM network
which the Company believes to be the most advanced in the world. MFS Datanet
uses the Company's networks for customers located in buildings where the
Company already provides special access, private line or switched services,
requiring significantly less capital expenditures because data communications
customers can, to a certain extent, utilize existing fiber optic networks,
electronics and building equipment rooms. The Company will incur additional
capital costs for the installation of new revenue producing circuits. The
level of costs may vary based upon the type of circuit installed and the
location of the customer.

  The MFS Intelenet Companies. Through MFS Intelenet, the Company provides a
single source for integrated local and long distance telecommunications
services and facilities management to small and medium sized businesses. By
utilizing its existing networks and facilities, the Company minimizes capital
expenditures for transmission facilities. However, significant capital costs
have been and will be incurred for switching equipment, equipment maintained
at customer locations and additional building wiring costs.
 
  MFS International. Through MFS International, the Company provides
telecommunication services to business and government users in several major
European metropolitan areas as well as outbound international service from the
United States and Europe. The Company is offering services over its networks,
or through resale of international telecommunications services in London,
England, Frankfurt, Germany, Paris, France, Stockholm, Sweden and Zurich,
Switzerland and Hong Kong.
 
  Global Network Services. Through Global Network Services, the Company
manages the operation of its network and future network development in order
to offer the services described above in a cost effective manner.
 
  The incurrence of significant initial development and roll out expenses in
advance of anticipated future revenues will continue to affect the operating
results of the Telecommunications Services segment. Anticipated sales growth
in the telecommunication services segment will also continue to drive
increasing deployment of electronic equipment required to initiate customer
service.
 
  Network Systems Integration Services
 
  The Company, primarily through MFS Network Technologies, designs, engineers,
develops and manages the installation of the Company's new fiber optic
networks and network expansions. In 1991, the Company began to offer network
systems integration services to third parties. These services have been
characterized by significant revenues concentrated in a relatively small
number of large projects for third parties. In 1993, the Company also began to
offer services related to Intelligent Transportation Systems ("ITS"). The
Company recognizes revenue based upon the amount of network systems
integration services performed. The amount of the Company's network systems
integration services performed can vary on a quarterly basis depending upon
individual customer contract requirements.

 Telecommunications Services
 
  Telecommunications services revenue increased to $165.6 million in the three
months ended March 31, 1996 from $103.8 in the three months ended March 31,
1995, an increase of $61.8 million, or 60%. Revenues in the three months ended
March 31, 1996 and March 31, 1995 for each of the key elements of the
telecommunications segment were as follows:

  The increases resulted from increased market penetration of all
telecommunications services of the Company. The especially large increase in
revenues, measured on a percentage basis, from MFS International reflects
strong sales in the United Kingdom and a growing revenue base in continental
Europe.
 
  Since the end of 1993, the Company has separately tracked the MFS Telecom
results of operations for the 14 network cities and expansions that were
materially complete at year end 1993 (the "Base Cities Competitive Access
Operations"). These Base Cities Competitive Access Operations produced revenue
of $39.6 million in the three months ended March 31, 1996 and $28.8 million in
the three months ended March 31, 1995, an increase of $10.8 million, or 38%.
The increase in revenue from these operations resulted primarily from
increased market penetration in these cities. Due to a
 
                                      38
<PAGE>
 
modification of the Company's internal organization within the
telecommunications services segment it will become increasingly less
meaningful to separate the Base Cities Competitive Access Operations from
other operations because of the increasing commonality of revenues and costs
within Base Cities Competitive Access Operations, expansions and types of
services. For this reason, the Company may discontinue separate disclosure for
these Base Cities Competitive Access Operations in the future. The Company
continues to review other modifications to its financial disclosures which the
Company believes will provide more meaningful information about its
activities.
 
  Annualized monthly recurring revenue increased to approximately $700 million
at March 31, 1996 from approximately $430 million at March 31, 1995, an
increase of 63%. The increase reflects primarily the sales of additional
services to current and new customers in existing and new markets. Monthly
recurring revenue represents monthly service charges billable to
telecommunications services customers as of the last day of the period
indicated, but excludes non-recurring revenues for certain one-time services,
such as installation fees or equipment charges.
 
  Telecommunications services operating expenses increased to $156.4 million
or 94% of segment revenue in the three months ended March 31, 1996 from $107.5
million or 104% of segment revenue in the three months ended March 31, 1995,
an increase of $48.9 million. The change includes an increase of $41.5 million
in circuit charges, including local and long distance service costs, and
personnel costs necessary to support the Company's growth. The remaining
increase of $7.4 million relates to increased rent, utilities, and other costs
incurred to support the increased revenue base. Telecommunications services
operating expenses consist of costs associated directly with network
operations, including salaries, sales commissions and related employee
benefits, rent expense, right-of-way fees, other network costs and local and
long distance service costs.
 
  Telecommunications services depreciation and amortization expense increased
to $44.0 million in the three months ended March 31, 1996 from $28.5 million
in the three months ended March 31, 1995, an increase of $15.5 million or 54%.
The increase is primarily related to the expanded fixed asset base of the
Company's networks, which includes increasing amounts of electronic equipment
with depreciable lives that are shorter than the Company's other major fixed
asset categories.
 
  Telecommunications services general and administrative expenses increased to
$31.2 million in the three months ended March 31, 1996 from $23.2 million in
the three months ended March 31, 1995, an increase of $8.0 million or 34%. The
change is primarily due to an increase of $7.2 million in personnel costs.
Management of the Company expects general and administrative services to
continue to increase during 1996 as the Company expands its services.
 
  Telecommunications EBITDA loss decreased to $(18.8) million in the three
months ended March 31, 1996 from $(26.9) million in the three months ended
March 31, 1995. EBITDA in 1996 and 1995 for each of the key elements of the
telecommunications segment were as follows:

</TABLE>
 
The increase at the MFS Telecom Companies reflects the high incremental
margins inherent in the dedicated special access and private line services
primarily provided over the Company's own facilities. The small decrease in
EBITDA loss at MFS Intelenet reflects the additional EBITDA margins provided
by increased revenues resulting from a sales strategy that emphasized the
provision of local switch services in advance of the implementation of the
Telecommunications Act of 1996 offset by the additional costs incurred to
expand the integrated local and long distance telecommunications service

markets including normal increases in operating expenses. The small increase
in EBITDA loss at MFS International reflects the additional EBITDA margins
provided by increased revenues offset by the additional costs incurred to
expand the Company's international service, particularly in new markets.
 
  The Base Competitive Access Operations produced EBITDA of $20.5 million
before parent company allocations in the three months ended March 31, 1996 and
$12.8 million in the three months ended March 31, 1995, an increase of $7.7
million, or 60%. For reasons noted earlier, the Company may discontinue
separate disclosure for these Base Cities Competitive Access Operations in the
future. The Company continues to review other modifications to its financial
disclosures which the Company believes will provide more meaningful
information about its activities.
 
 Network Systems Integration Services
 
  Third party revenue from services offered by the Company's network systems
integration services segment increased to $20.7 million in the three months
ended March 31, 1996 from $14.6 million in the three months ended March 31,
1995, an increase of $6.1 million or 42%. The increase is primarily due to an
increase in the amount of revenue recognized from projects involving ITS
services and to a lesser extent other network systems integration projects.
 
  Network systems integration services operating expenses increased to $17.8
million in the three months ended March 31, 1996 from $12.4 million in the
three months ended March 31, 1995, an increase of $5.4 million or 44%. The
increase is primarily due to the increased level of operating expenses related
to the projects noted above, including the continuing development and
investments in ITS service projects. Network systems integration operating
expenses consist of direct costs associated with the network systems
integration projects.
 
  Network systems integration services general and administrative expenses
increased to $3.7 million in the three months ended March 31, 1996 from $2.8
million in the three months ended March 31, 1995, an increase of $.9 million
or 32%. The increase reflects the increased third party work noted above.
 
  Network systems integration services EBITDA loss was $(.6) million in the
three months ended March 31, 1996 which matches the EBITDA loss for the three
months ended March 31, 1995. This resulted from the increased operating and
general administrative expenses offsetting increased revenues.
 
 Other Income (Expense)
   
  Other income (expense) increased to $18.8 million of other expense in the
three months ended March 31, 1996 from $7.3 million of other expense in the
three months ended March 31, 1995. The increase in other expense resulted
primarily from additions to interest expense incurred in connection with the
issuance of the 1996 Senior Discount Notes. This increase was partially offset
by increased interest income from the investment of the proceeds of the 1996
Senior Discount Notes.     
 
 Income Taxes
 
  The income tax expense of $.1 million in the three months ended March 31,
1996 and 1995, resulted from estimated state and foreign tax liabilities.
 
 Net Loss
 
  Net loss increased to $86.2 million in the three months ended March 31, 1996
from $64.0 million in the three months ended March 31, 1995, an increase of
$22.2 million. The increase resulted primarily from increased depreciation,
amortization and interest expense.

The increases resulted from increased market penetration of all
telecommunications services of the Company. The increase at MFS Intelenet
Companies is also related to the acquisitions of Centex Telemanagement, Inc.,
("Centex"), which was acquired in May 1994, and RealCom Office Communications,
Inc., ("RealCom"), which was acquired in November 1994. The increase at MFS
Telecom Companies is also related to the acquisition of Cylix Communications
Corporation ("Cylix"), which was acquired in November 1994.
 
  During 1994 and 1995 the Company separately tracked the MFS Telecom results
of the Base Cities Competitive Access Operations. These Base Cities
Competitive Access Operations produced revenue of $129.7 million in 1995 and
$93.9 million in 1994, an increase of $35.8 million, or 38%. The increase in
revenue from these operations resulted primarily from increased market
penetration in these cities.
 
  Annualized monthly recurring revenue increased to approximately $625 million
at December 31, 1995 from approximately $380 million at December 31, 1994, an
increase of 64%. The increase reflects primarily the sales of additional
services to current and new customers in existing and new markets and
additional market penetration resulting in new customers. Monthly recurring
revenue represents monthly service charges billable to telecommunications
services customers as of the last day of the period indicated, but excludes
non-recurring revenues for certain one-time services, such as installation
fees or equipment charges.
 
  Telecommunications services operating expenses increased to $488.7 million
or 98% of segment revenue in 1995 from $225.5 million or 99% of segment
revenue in 1994, an increase of $263.2 million or 117%. The increase is
primarily due to an increase of $137.8 million in network operating expense
directly related to the increase in telecommunications service levels for
existing and new customers. Network operating expenses primarily represents
the portion of total operating expenses that are paid to third parties for
local and long distance service costs, including right-of-way fees. The
increase in total telecommunications services operating expenses also includes
an increase of $66.4 million in personnel costs necessary to support the
Company's revenue growth and expanded operations. The remaining increase of
$59.0 million in total telecommunications services operating expense relates
to increased rent, utilities and other costs incurred to support the Company's
growth. Telecommunications services operating expenses consist of local and
long distance service costs and costs associated directly with network
operations, including salaries, sales commissions and related employee
benefits, rent expense, right-of-way fees and other network costs.

  Telecommunications services depreciation and amortization expense increased
to $139.9 million in 1995 from $72.2 million in 1994, an increase of $67.7
million, or 94%. The increase is primarily related to the expanded fixed asset
base of the Company's networks, which includes increasing amounts of
electronic equipment with depreciable lives that are shorter than the
Company's other major fixed asset categories, and an increase of $13.4 million
in amortization of intangible assets resulting from the acquisitions of
Centex, RealCom and Cylix.
 
  Telecommunications services general and administrative expenses increased to
$103.6 million in 1995 from $62.2 million in 1994, an increase of $41.4
million, or 67%. The increase is primarily due to increases of $14.3 million
in personnel costs and $8.9 million in legal and other professional services
costs necessary to support the Company's growth. The remaining increase of
$18.2 million related primarily to rents and other costs necessary to support
the expanding services of the Company.
 
  Telecommunications services EBITDA decreased to $(94.1) million in 1995 from
$(59.0) million in 1994, a decrease of $35.1 million. EBITDA in 1995 and 1994

The decrease reflects the increasing operating and general and administrative
costs noted earlier primarily caused by the Company's growth, including the
expansion of MFS Intelenet, MFS Datanet and MFS International. The Base
Competitive Access Operations produced EBITDA of $61.8 million before parent
company allocations in 1995 and $35.8 million in 1994, an increase of $26.0
million, or 73%.
 
 Network Systems Integration Services
 
  Third party revenue from services offered by the Company's network systems
integration services segment increased to $85.0 million in 1995 from $58.0
million in 1994, an increase of $27.0 million, or 47%. The increase is
primarily due to an increase in the amount of revenue recognized from the
network systems integration projects for Bay Area Rapid Transit and other
projects involving network systems integration and ITS services, which were
partially offset by decreases in revenue recognized from other network systems
integration projects. Services that the network systems integration segment
provided to MFS Telecom, which are eliminated from revenue and cost in the
Consolidated Financial Statements, amounted to $137.0 million in 1995 as
compared to $97.8 million in 1994.
 
  Network systems integration services operating expenses increased to $73.6
million in 1995 from $48.0 million in 1994, an increase of $25.6 million, or
53%. The increase is primarily due to the increased level of operating
expenses for the network systems integration projects and to several projects
involving ITS services noted earlier. Network systems integration services
operating expenses consist of direct costs associated with the third party
network systems integration projects.
 
  Network systems integration services general and administrative expenses
increased to $14.0 million in 1995 from $13.3 million in 1994, an increase of
$.7 million, or 5%. The increase reflects primarily an increase in costs
related to the increased third party work noted above.
 
  Network systems integration services EBITDA increased to $(2.7) million in
1995 from $(3.3) million in 1994, an increase of $.6 million. The increase is
primarily due to the increased third party work noted above.

 Other Income (Expense)
 
  Other income (expense) increased to $(28.0) million in 1995 from $(17.2)
million in 1994. The increase resulted primarily from decreased interest
income from investments, due primarily to lower investment balances during
1995.
 
 Income Taxes
 
  The income tax expense of $.6 million for 1995 resulted from state and
foreign tax liabilities. The income tax benefit of $2.1 million for 1994
resulted from the utilization of tax benefits recognized for losses incurred
during 1994 that reduced the net deferred tax liability.
 
 Net Loss
 
  Net loss increased to $267.9 million in 1995 from $151.2 million in 1994, an
increase of $116.7 million. The increase resulted primarily from increased
depreciation and amortization, the increased operating losses incurred in
expanding MFS Intelenet, MFS Datanet and MFS International and decreased
interest income.
 
 Backlog
 
  The network systems integration segment had backlog of approximately $163
million at December 31, 1995. Backlog consists of firm contracts less revenue
recognized to date by the Company.
 
  YEAR ENDED 1994 VS. YEAR ENDED 1993
 
 Telecommunications Services
 
  Telecommunications services revenue increased to $228.7 million in 1994 from
$70.0 million in 1993, an increase of $158.7 million, or 227%. Over 70% of the
increase relates to the acquisitions of Centex, RealCom and Cylix during 1994.
The remaining increase resulted primarily from increased market penetration of
all other telecommunications services of the Company. The Base Competitive
Access Operations produced revenue of $18.7 million in the fourth quarter of
1993, $19.8 million in the first quarter of 1994, $22.3 million in the second
quarter, $25.0 million in the third quarter and $26.8 million in the fourth
quarter.
 
  Annualized monthly recurring revenue increased to approximately $380 million
at December 31, 1994 from approximately $81 million at December 31, 1993, an
increase of 369%. The increase reflects primarily the operations of Centex,
RealCom and Cylix and the sales of additional services to current and new
customers in existing and new markets, and to a lesser extent, additional
market penetration resulting in new customers. Excluding acquisitions,
annualized monthly recurring revenue would have been approximately $150
million at December 31, 1994, an increase of 84% over the year end 1993
amount.
 
  Telecommunications services operating expenses increased to $225.5 million
or 99% of segment revenue in 1994 from $47.7 million or 68% of segment revenue
in 1993, an increase of $177.8 million, or 373%. The increase is primarily due
to the operating expenses of the Centex, RealCom and Cylix operations which
were acquired in 1994. The remaining increase includes higher costs associated
with expansion activities of MFS Intelenet, MFS Datanet and MFS International
and higher costs associated with new and expanded networks.
 
  Telecommunications services depreciation and amortization expense increased
to $72.2 million in 1994 from $33.8 million in 1993, an increase of $38.4
million, or 114%. The increase is primarily
 
                                      43
<PAGE>
 
related to the expanded fixed asset base of the Company's networks and an
increase of $13.5 million in amortization of intangible assets resulting from
the acquisitions of Centex and RealCom in 1994. Depreciation and amortization
relating to MFS Datanet and MFS Intelenet also increased $6.0 million,
excluding acquisitions.
 
  Telecommunications services general and administrative expenses increased to
$62.2 million in 1994 from $23.0 million in 1993, an increase of $39.2
million, or 170%. The increase is primarily due to the acquisitions of the
Centex, RealCom and Cylix operations which were acquired in 1994. The
remaining increase is related to higher costs associated with expanding MFS
Intelenet, MFS Datanet and MFS International.
 
  Telecommunications services EBITDA decreased to ($59.0) million in 1994 from
($1.2) million in 1993. The decrease reflects the additional costs incurred
developing the services of MFS Datanet, MFS Intelenet and MFS International
offset by improving EBITDA generated by the MFS Telecom metropolitan area
networks. EBITDA for the Base Competitive Access Operations was $35.8 million
in 1994 before parent-company allocations. The Base Competitive Access
Operations produced EBITDA of $5.9 million before parent-company allocations
in the fourth quarter of 1993, $6.3 million in the first quarter of 1994, $8.0
million in the second quarter, $10.1 million in the third quarter and $11.4
million in the fourth quarter. EBITDA margin for these operations improved
from 31.7% for the last quarter of 1993 to 42.6% for the last quarter of 1994.
MFS Intelenet, MFS Datanet and MFS International generated EBITDA of ($87.2)
million in 1994 and ($22.4) million in 1993, a decrease of $64.8 million.
 
 Network Systems Integration
 
  Third party revenue from services offered by the Company's network system
integration segment decreased to $58.0 million in 1994 from $71.1 million in
1993, a decrease of $13.1 million, or 18%. The decrease is primarily due to a
decrease in the amount of revenue recognized from the network systems
integration project for the State of Iowa and to an increased focus on the
design and construction of the Company's own networks. Services that the
network systems integration segment provided to MFS Telecom, which are
eliminated from revenue and cost in the Consolidated Financial Statements,
amounted to $97.8 million in 1994 as compared to $44.9 million in 1993.
 
  Network systems integration services operating expenses decreased to $48.0
million in 1994 from $55.2 million in 1993, a decrease of $7.2 million, or
13%. The decrease is primarily due to the decreased level of operating
expenses for the network systems integration project for the State of Iowa,
which was partially offset by increases in expenses recognized from other
network systems projects.
 
  Network systems integration services general and administrative expenses
increased to $13.3 million in 1994 from $12.0 million in 1993, an increase of
$1.3 million, or 11%. The increase reflects primarily the costs of additional
employees, travel and consultants associated with the segment's increased
marketing and proposal activity, including activity related to ITS services.
 
  Network systems integration services EBITDA decreased to ($3.3) million in
1994 from $4.4 million in 1993. The decrease is primarily due to decreased
operating margins from network system integration projects and to the
increased marketing and proposal activity related to ITS services.
 
 Other Income (Expense)
 
  Other income (expense) decreased to $17.2 million of other expense in 1994
from $8.5 million of other income in 1993. The decrease resulted primarily
from increased interest expense associated with the issuance of Senior
Discount Notes in January 1994, offset by increased interest income from the
investment of the proceeds of the debt issue.
 
 
                                      44
<PAGE>
 
 Income Taxes
 
  The income tax benefit of $2.1 million in 1994 resulted from the utilization
of tax benefits recognized for losses incurred during 1994 that reduced the
net deferred tax liability.
 
 Net Loss
 
  Net loss increased to $151.2 million in 1994 from $15.8 million in 1993, an
increase of $135.4 million. The increase resulted primarily from the increased
operating losses incurred in developing single-source telecommunications
services and high-speed date communications, increased interest expense and
increased depreciation and amortization.
 
 Backlog
 
  The network systems integration segment had backlog of approximately $127
million at December 31, 1994.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  The Company's total assets have increased from $5.0 million at December 1988
to $2.3 billion at March 31, 1996. The Company's growth was funded by capital
contributions from its former majority stockholder, KDG, until an initial
public offering in 1993. Since that public offering, the Company has funded
its growth through a combination of debt and equity financing including, most
recently, a debt offering in January 1996 of the 1996 Senior Discount Notes.
As of March 31, 1996, the Company's current assets of $721.7 million,
including cash and marketable securities aggregating $460.9 million, exceeded
current liabilities of $267.7 million, providing working capital of $454.0
million. Network and equipment, net of depreciation, comprise $1.2 billion of
total assets.
   
  The Company's operating activities used net cash of $52.4 million in the
three months ended March 31, 1996 and $21.3 million in the three months ended
March 31, 1995. The increase in cash used by operating activities was
primarily due to the increased loss from operations incurred expanding the
Company's services and an increase in cash used supporting increased levels of
accounts receivable and other assets which is partially offset by increased
depreciation, amortization and non-cash interest expense. The Company's
operating activities provided (used) net cash of $(120.7) million, $(10.4)
million and $32.9 million in the years ended December 31, 1995, 1994 and 1993,
respectively. The increases in cash used by operating activities in 1995 and
1994 were primarily due to the increased loss from operations incurred in
expanding the operations of MFS Intelenet, MFS Datanet and MFS International,
which were partially offset by increased depreciation and amortization, as
well as an increase in cash used supporting increased levels of accounts
receivable and other assets.     
   
  In order to finance the Company's operations and network development, the
Company has utilized a variety of financing vehicles including the sale of
common and preferred stock, the issuance of Senior Discount Notes and
arranging various other credit facilities. These transactions have resulted in
net cash provided by financing activities of $527.7 million in the three
months ended March 31, 1996, and $386.0 million, $488.5 million and $532.7
million for the years ended December 31, 1995, 1994 and 1993, respectively.
The Company's capital expenditures, including the acquisitions of businesses,
aggregated $148.4 million in the three months ended March 31, 1996, and $523.7
million, $576.7 million and $128.7 million in the years ended December 31,
1995, 1994 and 1993, respectively.     
 
  At March 31, 1996, the Company had approximately $840 million of available
liquidity, including cash, marketable securities and unused lines of credit.
       
                                      45
<PAGE>
 
   
  On May 7, 1996, the Company announced that it intends to undertake certain
initiatives designed to take advantage of opportunities created by changes in
telecommunications laws and the rapid development of Internet-based
communications networks. These initiatives involve increasing the number of
cities served, expanding its networks in existing cities, constructing and
acquiring its own intercity and submarine high capacity network, accelerating
central office interconnection, deployment of additional switches, and
providing high-speed local Internet access.     
   
  Expenditures for the initiatives are subject to the Company's review of a
number of factors including cost of any additional capital required,
technological developments and market conditions. In addition, each initiative
may be implemented in whole or in part, and independently of any other
initiative, ensuring that the Company retains maximum financial and operating
flexibility. The Company anticipates that implementation of these initiatives
including certain of the Internet-related initiatives, will, together with
currently anticipated expenditures, result in total average annual capital
expenditures of approximately $1.0 billion to $1.3 billion over the period of
implementation, which the Company expects to be up to four years. Since a
significant portion of the Company's capital expenditures are success-based
(that is, related directly to revenue growth), actual capital expenditures may
vary significantly from the above range depending on the level of incremental
sales. This range is also subject to a number of factors, including the pace
and extent of network development, levels of incremental sales, as well as
regulatory actions by state, federal and international authorities, which,
individually or in the aggregate, could cause material changes in capital
expenditure requirements. The proceeds of the Offerings will be used to fund a
portion of these expenditures. See "Use of Proceeds." The Company expects to
fund the balance of its capital requirements through the net proceeds from the
Offerings to the extent that they are not used to fund the initial capital
expenditures related to the May 7th initiatives, existing resources,
internally generated funds and additional debt or equity financing as
appropriate.     
 
MERGER WITH UUNET
 
  The Company announced that it has executed the Merger Agreement with UUNET.
Under the terms of the Merger Agreement, which includes a fixed conversion
ratio, each share of UUNET Common Stock will be converted into 1.777776 shares
of MFS Common Stock. The transaction value is approximately $2 billion based
on the Company's stock price at the date of the announcement. The Company
intends to utilize purchase accounting to record the transaction and, as a
result, will incur substantial amortization charges for the next five years.
The Merger Agreement was unanimously approved by the members of the Board of
Directors of each company present. In addition, stockholders of UUNET owning
approximately 60% of the outstanding shares of UUNET Common Stock and
stockholders of MFS owning approximately 12% of the outstanding shares of MFS
Common Stock prior to the Offerings have committed to vote in favor of the
Merger.
 
OTHER MATTERS
 
  As evidenced by the Merger Agreement, the Company from time to time
evaluates acquisitions in pursuit of its business strategy, either as an
alternative to constructing networks, adding customers, or to the introduction
of services that complement existing and/or planned services. Such
acquisitions may be significant in size and could use a substantial portion of
the Company's available cash.
 
  From time to time, the Company has had discussions with other communications
entities concerning the establishment of possible strategic relationships,
including transactions involving substantial acquisitions, combinations and
equity investments in the Company or one of its subsidiaries. In addition,
certain acquisitions may provide the Company with the opportunity to acquire
an established customer base. The Company intends to consider appropriate
opportunities to establish strategic relationships.

ACCOUNTING FOR STOCK-BASED COMPENSATION
 
  In October 1995, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards No. 123 ("SFAS 123"), Accounting
for Stock-Based Compensation. SFAS 123 encourages entities to adopt a fair
value based method of accounting for employee stock compensation plans,
however it also allows an entity to continue to measure compensation cost for
those plans using the intrinsic value based method of accounting. Under the
intrinsic value based method, many companies, including MFS, have not
recognized compensation cost for many of their stock compensation plans.
 
  The Company believes that the fair value method of accounting more
appropriately reflects the substance of the transaction between an entity that
issues stock options, or other stock-based instruments, and its employees;
that is, an entity has granted something of value to an employee (the stock
option or other instrument) generally in return for their continued employment
and services. The Company believes that the value of the instrument granted to
employees should be recognized in financial statements because nonrecognition
implies that either the instruments have no value or that they are free to
employees, neither of which is an accurate reflection of the substance of the
transaction. Although the recognition of the value of the instruments results
in compensation expense in an entity's financial statements, the expense
differs from other common compensation expenses in that these charges will not
be settled in cash, but rather through issuance of common stock.
 
  The Company has introduced certain changes to its stock-based compensation
plans, including a new option plan for key executive employees which
ultimately have value to the employee only if the Company's stock price
outperforms the S&P 500. The Company granted approximately 450,000 options
under the new option plan on January 1, 1996, and anticipates that additional
grants will be made on a quarterly basis. The Company believes that the
adoption of the standard will result in material non-cash charges to
operations in 1996 and thereafter. The amount of the non-cash charge will be
dependent upon a number of factors, including the number of options granted
and the fair value estimated at the time of grant.
 
EFFECTS OF INFLATION
 
  Inflation has not had a significant effect on Company operations. However,
there can be no assurance that inflation will not have a material effect on
the Company's operations in the future.

                                   BUSINESS
 
INTRODUCTION
 
  MFS is an integrated communications provider ("ICP") of local and long
distance telecommunications services and certain Internet-related services to
business and government end users. The Company provides services by utilizing
its International Network Platform in the United States, Western Europe and
Asia. As the first ICP to focus on business and government customers, the
Company believes it is uniquely positioned to take advantage of technical
regulatory and market changes which promote demand for an integrated set of
communications services.
 
  The Company's strategy is to become the premier provider of communications
services to business and government end users. The Company believes business
and government end users have distinct communications service requirements,
including maximum reliability, consistent high quality, responsive customer
service and continuous attention to service enhancement and new service
development. The Company believes it has multiple advantages over its
competitors as a result of the Company's: (i) focus on business and government
end users; (ii) expertise in developing and operating highly reliable,
advanced digital fiber optic networks which offer substantial transmission
capacity; (iii) emphasis on providing comprehensive and responsive customer
service; (iv) International Network Platform that serves customers with
multiple offices in key international business centers; (v) network
development plan which helps assure an efficient evolution from a voice-
oriented, circuit switched network to an IP Packet switched network; (vi) plan
to develop new services, including voice service to be provided over an IP
Packet switched network; and (vii) ability to bundle local, long distance
telecommunications services and Internet-related services provided over an
end-to-end network controlled by the Company.
 
  As part of the implementation of its IP Packet switched network and
Internet-based service offering plans, the Company entered into the Merger
Agreement with UUNET pursuant to which UUNET will become a wholly owned
subsidiary of MFS. See "Description of the Merger."
 
  The Company is organized as a holding company and operates through its
subsidiaries in two business segments: telecommunications services and network
systems integration.
 
 Telecommunications Services
 
  . The MFS Telecom Companies serve the needs of large businesses and
    government customers by providing dedicated circuits, local switched
    services and high speed data communications for large corporations.
 
  . The MFS Intelenet Companies serve the needs of medium and small
    businesses by providing integrated local and long distance switched
    telecommunications and telecommunication management services and a variety
    of value-added services including voice mail, calling card and specialized
    call accounting.
 
  . MFS International serves the needs of communications intensive national
    and multinational corporations in global financial centers, primarily in
    Western Europe, by providing a full range of local, long distance,
    international and data communications services as permitted by regulation
    in the relevant jurisdiction.
 
  . MFS Global Network Services expands and manages the Company's
    International Network Platform which consists of the Company's own
    facilities and switching platform as well as capacity leased from other
    service providers.
 
  . After the Merger, through UUNET the Company will provide a wide range of
    Internet-related services tailored to the needs of business and government
    users, including a comprehensive range of dial-up and dedicated Internet
    access options, consulting services and Web server hosting and integration
    services.
 
                                      48

 Network Systems Integration
 
  MFS Network Technologies provides network systems integration for MFS and
third parties, which desire to deploy sophisticated networks, including
intelligent transportation systems, voice and data networks, interactive
distance learning networks, security systems and combined cable television-
telephone networks.
 
RECENT DEVELOPMENTS
 
  The pace of regulatory and technical change in the telecommunications
industry has continued to accelerate. The Telecom Act was signed into law on
February 8, 1996, effectively creating, among other things, a national
template under which the Company's services may be provided on a more equal
basis with incumbent local telephone companies once the Telecom Act is
implemented. Technical change has also been dramatic, particularly with
respect to Internet-related products and services, as a rapidly growing amount
of information available on both the Internet and on privately managed
"intranets" is made increasingly accessible with advanced software and
hardware. MFS has responded to these developments with several new
initiatives.
 
 The Telecommunications Act of 1996
 
  The Telecom Act has a number of provisions that affect the Company's
operations in ways that are difficult to predict with precision. The Company
believes that the Telecom Act is generally pro-competitive and will, on
balance, benefit the Company by, among other things, opening local exchange
markets to competition, preempting anti-competitive state laws and granting
the Company regulatory status more equal with that of the incumbent local
telephone companies. The Company believes the following attributes of the
Telecom Act will have certain positive effects on the Company's operations.
 
  . Market access. Opening all U.S. markets to local competition.
 
  . Network interconnections. Enabling the Company to more fully interconnect
   its networks with incumbent local telephone companies and other carriers
   to allow the Company to reach customers not physically connected to its
   own networks in a more cost effective manner.
 
  . Number portability. Enabling business customers to retain their existing
   phone numbers in the event they choose to switch local service providers.
   The Company considers number portability to be a significant factor which
   can positively influence a customer's decision to purchase service from
   MFS.
 
  . Reciprocal compensation. Ensuring that other carriers, both local and
   long distance, compensate the Company for calls made to its customers or,
   in the alternative, not charge the Company for calls made by its customers
   to the customers of other carriers. The Company believes that such
   reciprocal compensation arrangements will improve its operating margins
   over time.
 
  The Company has moved quickly to capitalize on the anticipated benefits of
the Telecom Act. MFS has contacted 21 LECs to initiate the process of
implementing the "co-carrier" provisions of the Telecom Act as quickly as
possible and has established a co-carrier task force consisting of
approximately 100 personnel dedicated to facilitate the negotiation and
implementation of co-carrier arrangements with the LECs. On May 22, 1996, MFS
announced that it and Ameritech had entered into a comprehensive co-carrier
agreement which involves the networks of the respective companies in the
entire Ameritech marketing region, including Illinois, Indiana, Michigan, Ohio
and Wisconsin.
   
  Included in the agreement with Ameritech are provisions relating to:
interconnection at any technically feasible point within Ameritech's network;
interim number portability; access to poles, ducts, conduits and rights-of-way
controlled by Ameritech; exchange of all local traffic at a fully reciprocal
per minute rate; receipt by MFS of terminating access charges for long
distance calls made to its     
 
                                      49
<PAGE>
 
   
customers; and nondiscriminatory access to 911 and emergency 911 services,
directory assistance services, operator call completion services and white
pages directory listings for MFS' customers.     
 
 New Infrastructure Initiatives
 
  In response to the regulatory developments embodied in the Telecom Act,
increased demand for high bandwidth communications capacity, and the Company's
success in its previous business development initiatives, MFS announced on May
7, 1996 a series of initiatives which, when implemented, will expand the
Company's geographic presence and service offerings in a large number of U.S.
metropolitan areas and certain international financial centers. The Company
anticipates that implementation of these initiatives including certain of the
Internet-related initiatives discussed below, will, together with currently
anticipated expenditures, result in total average annual capital expenditures
of approximately $1.0 billion to $1.3 billion over the period of
implementation, which the Company expects to be up to four years. Since a
significant portion of the Company's capital expenditures are success-based
(that is, related directly to revenue growth), actual capital expenditures may
vary significantly from the above range depending on the level of incremental
sales. This range is also subject to a number of factors, including regulatory
developments, technological developments and market conditions. In addition,
each initiative may be implemented in whole or in part and independently of
any other initiative, ensuring that the Company retains maximum financial and
operating flexibility.
 
  Construction and Expansion of Networks. The Company plans to expand the
number of U.S. metropolitan areas served to approximately 85 over the next
four years, an increase from the previously planned target of approximately 65
metropolitan areas, 45 of which are currently in operation or under active
development. In addition, the Company plans to construct approximately 35
major expansions of existing networks. The actual number of new metropolitan
areas and network expansions constructed may vary materially from these
targets. Taken together with the aforementioned regulatory developments, MFS
believes that, upon completion, these initiatives will enable the Company to
sell its services in metropolitan areas currently containing approximately 70%
of the non-farm business employment in the United States.
 
  The Company also intends to increase the number of international financial
centers served to 45, an increase from its previously planned target of 25,
seven of which are currently operational or under active development. A number
of the financial centers are expected to be developed in Asian countries where
regulatory reform has recently created opportunities to serve the needs of
communications intensive business customers. The pace of international
development is dependent on a number of factors, many of which are beyond the
Company's control, including the speed of regulatory reform.
 
  Intercity High Capacity Network. The Company intends to build or acquire a
significant portion of its U.S. and international high speed intercity and
transoceanic fiber optic networks, to be deployed over a two to four year
period. In accordance with this strategy, MFS has begun construction of
intercity connections along the Eastern seaboard with the intent of linking
the Company's metropolitan networks from Washington, D.C. to Boston.
Deployment of intercity networks with high speed SONET (or internationally,
the equivalent SDH standard) equipment is expected to lower the cost of long
distance connections and, in combination with MFS' high capacity local
networks, enable the Company to provide a range of new Internet-related
services including, over time, high quality voice and video communications
service. The pace of construction and number of connections actually built
will depend on a number of factors, including availability of rights-of-way,
market conditions, and the availability of certain high speed SONET services
from other carriers, which could serve as an alternative to the construction
of such connections. The Company currently leases certain medium bandwidth
(DS-3 or equivalent) international long distance connections from other
providers, the cost of which represents a significant portion of the Company's
network expense.
 
 
                                      50
<PAGE>
 
  Central Office Interconnection and Switch Deployment. The Company plans to
interconnect at LEC central offices in all its network metropolitan areas and
plans to deploy approximately 25 additional switches over the 25 previously
planned. The Telecom Act mandates that incumbent LECs throughout the U.S.
enter into arrangements with competitors such as MFS for central office
collocation and unbundling of local services. The Company believes that
implementing these pro-competitive policies creates a unique opportunity to
expand the Company's offering of combined local and long distance services
through interconnection with local exchange carriers.
 
 Internet-Related Initiatives
 
  The Company believes the Internet is one of the most important developments
in the communications industry in decades. The recent rapid development of the
Internet, along with Internet-related technologies, products and services
(especially intranet applications), will continue to stimulate accelerated
growth in demand for communications bandwidth. MFS believes IP Packet
switching will, over time, replace large portions of the circuit switched
voice network as the primary vehicle for business communications due to the
efficient use of bandwidth and the significantly lower transmission costs
associated with IP Packet switching. The amount of data transmitted over the
Internet backbone has grown very rapidly as a result of expanded Internet use
and the increasing complexity of information delivered via the Internet.
Currently, Web pages available on the Internet frequently include graphics
and, in some cases, sound and video, which require the transfer of more data
to the user's computer than do comparable text-only pages. See "Business--
Communications Industry Overview--Internet."
 
  MFS believes that availability of local loop bandwidth is the greatest
barrier to Internet development. The Company believes that its ability to
provide end-to-end high capacity bandwidth, unimpeded by a bottleneck at any
point along the path, uniquely positions it to provide superior business-
oriented Internet-related services.
 
  Given the Internet's rapid pace of growth, MFS believes that speed to market
also will be a major competitive advantage. On May 7, 1996, the Company
announced that it has undertaken several initiatives designed to augment its
Internet-related service offerings, including increasing and accelerating
network development and expansions, procurement of high-speed local loop
circuits, control of intercity high capacity fiber optic links discussed above
and, as announced on April 30, 1996, the Company's planned merger with UUNET.
 
  In the United States, the acceleration of central office interconnection
arrangements and the availability of unbundled local loops is expected to
enable the Company to offer a variety of higher speed local Internet access
services based on ISDN (Integrated Service Digital Network) technology and, in
the future, on such technologies as ADSL (Asymmetric Digital Subscriber Loop)
and HDSL (High Speed Digital Subscriber Loop). In addition, the Company plans
to significantly expand its existing "Internet Hotel" space (that is,
facilities space specifically created to allow Internet service providers, Web
page hosting service providers and others to collocate with and utilize the
network services of the Company). Internationally, the Company intends to
pursue a range of new Internet initiatives similar to those planned for the
United States as regulatory reform and other factors allow, and to expand its
"Internet Hotel" space and international transport service in both Europe and
Asia.
 
  The Proposed Merger. On April 29, 1996, MFS and UUNET entered into the
Merger Agreement. If the Merger is consummated, UUNET will become a wholly
owned subsidiary of MFS. See "Risk Factors--Risk that Merger May Not Be
Consummated" and "Description of the Merger Agreement."
 
  UUNET is a leading worldwide provider of a comprehensive range of Internet
access options, applications and consulting services to businesses,
professionals and on-line service providers. MFS believes that the Merger will
(i) allow the Company to expand its communications service offerings to
 
                                      51

<PAGE>
 
include UUNET's existing array of Internet-related services oriented toward
the needs of business and government customers, (ii) provide the Company with
additional technical expertise in configuring and managing complex IP Packet
switched networks and (iii) over time, allow the Company to offer new services
(including voice and video communications services) utilizing UUNET's Internet
technology expertise and MFS' broadband, end-to-end networks. In addition, MFS
believes that the combined entity can, over time, improve profitability as a
result of (a) reduction in UUNET's "local loop" network costs (which UUNET
estimates to be approximately 40% of its "cost of revenues" in North America
for 1996) by utilizing available capacity on MFS' local networks, (b) receipt
of terminating access payments, or a reduction in cost of providing dial-up
Internet access, as mandated by the Telecom Act, (c) reduced cost of intercity
transport capacity purchased or leased from others as a result of increased
volume and migration of UUNET traffic to Company-owned facilities, and (d)
incremental sales from offering UUNET services combined with MFS services to
the customers of UUNET and the Company.
 
  Based on the number of shares of UUNET Common Stock outstanding at April 26,
1996, the Company expects to issue an aggregate of approximately 57.3 million
shares of MFS Common Stock in the Merger. Based on the closing price of the
MFS Common Stock on the day preceding the announcement of the Merger, the
stockholders of UUNET will receive shares of MFS Common Stock in the Merger
valued at approximately $2 billion.
 
  As a condition to entering into the Merger Agreement, MFS required certain
UUNET stockholders to enter into the Stock Option Agreement pursuant to which
such stockholders agreed to vote their shares of UUNET Common Stock in favor
of the approval of the Merger Agreement and granted irrevocable proxies in
favor of MFS to vote all of such stockholders' shares of UUNET Common Stock
(equal to approximately 60% of the issued and outstanding shares of UUNET
Common Stock). These stockholders also granted MFS an option (the "Option") to
purchase, under certain circumstances, all of such stockholders' shares of
UUNET Common Stock for the Exchange Ratio. Such stockholders have sole voting
and investment power with respect to all the UUNET Common Stock held of record
by them and therefore have sufficient voting power, without the vote of any
other holder of UUNET Common Stock, to determine the outcome of the vote on
the proposal to approve the Merger Agreement and any related transactions that
may come before the UUNET Special Meeting. Accordingly, by virtue of such
stockholders' ownership of approximately 60% of the outstanding UUNET Common
Stock, the proposal to adopt the Merger Agreement will be adopted without the
need of the vote of any other stockholders. See "Description of the Merger."
 
  As a condition to entering into the Merger Agreement, UUNET required certain
MFS stockholders, all of whom are directors of MFS, to enter into the MFS
Voting Agreement pursuant to which such MFS stockholders granted irrevocable
proxies in favor of UUNET to vote all of such stockholders' shares of MFS
Common Stock in favor of the MFS Share Proposal of MFS Common Stock in
connection with either the Merger or the Option. As of April 29, 1996, the
number of shares of MFS Common Stock subject to the irrevocable proxies equals
approximately 12% of the issued and outstanding shares of MFS Common Stock
prior to the Offerings. See "Description of the Merger."
 
COMMUNICATIONS INDUSTRY OVERVIEW
 
  The communications industry can be divided into two categories: the
telecommunications industry and the Internet.
 
 Telecommunications Industry
 
  Prior to the settlement in 1982 of antitrust litigation which resulted in
the break-up of AT&T in 1984 (the "Divestiture"), AT&T, sometimes referred to
as the Bell System, largely monopolized telephone service in the United
States. After the Divestiture regulatory changes and technological
developments
 
                                      52
<PAGE>
 
began to make it economically possible for companies (primarily
entrepreneurial enterprises) to compete for segments of the telephone
business.
 
  As part of the Divestiture, seven local exchange holding companies were
created to offer services in geographically defined areas called local access
and transport areas ("LATAs"). These Regional Bell Operating Companies
("RBOCs") were separated from the long distance provider, AT&T, resulting in
the creation of two distinct market segments: local exchange and interexchange
long distance. The Divestiture provided for direct, open competition in the
interexchange long distance segment.
 
  The terms of the Divestiture did not expressly address competition in the
local exchange market. Nonetheless, several factors served to promote the
emergence of competition in the local exchange market, including: (i) customer
desire for an alternative to the LEC monopoly, which desire grew rapidly and
was spurred in part by the development of competitive activities in the long
distance market; (ii) technological advances in the transmission of data and
video requiring greater capacity and reliability levels than copper-based LEC
networks were able to accommodate; (iii) a monopoly position and rate or
pricing structure which provided little incentive for the LECs to upgrade
their networks; and (iv) the development of fiber optics and digital
electronic technology, (such as synchronous optical network ("SONET")), which
combined the ability to transmit data and video at high speeds and greatly
increased capacity.
 
  The first competitors in the local exchange market, designated as
"competitive access providers" or "CAPs" by the FCC, were established in the
mid-1980s. In New York City, Chicago and Washington, D.C., newly formed
companies, provided non-switched services, known as special access and private
line, by installing fiber optic facilities connecting long distance carriers'
POPs within a metropolitan area and connecting end users (primarily large
businesses and government agencies) with long distance carriers. CAPs used the
substantial capacity and economies of scale inherent in fiber optic cable to
offer customer service that was generally less expensive and of higher quality
than could be obtained from the LECs due in part to the LECs' more antiquated
copper-based facilities. In addition, CAPs offered shorter installation and
repair intervals and improved reliability in comparison to the LECs.
 
  Most of the early CAPs were entrepreneurial companies operating limited
networks in the central business districts of major cities in the United
States where the highest concentration of voice and data traffic, including
long distance carrier traffic, were found. Initially, CAPs offered three
varieties of special access and private line services:
 
  . Long distance carrier to long distance carrier connections (special
    access), which use high capacity lines to transmit traffic between
    facilities of a long distance carrier or to transmit traffic from one long
    distance carrier to another long distance carrier;
 
  . End user to long distance carrier connections (special access), which
    generally use medium to high capacity lines to connect businesses to long
    distance carriers; and
 
  . End user to end user connections (private line), which generally use low
    to medium capacity lines to connect an end user's local offices.
 
  As CAPs proliferated during the latter part of the 1980s, regulators in some
states and at the federal level issued rulings which favored increased
competition and sought to open markets to new entrants. These rulings allowed
CAPs to offer a number of new services, including, in certain states in the
early and mid-1990s, a broad range of local exchange services.
 
  As certain companies deployed local circuit switches and began to offer a
limited set of local switched services, a new term, Competitive Local Exchange
Carriers ("CLEC") was created to distinguish these companies from CAPs, which
generally do not offer switched services. In order to
 
                                      53
<PAGE>
 
offer reasonably ubiquitous local switched services in a particular area,
CLECs (and the Company) must negotiate complex interconnection agreements with
the incumbent LEC, dealing with such issues as network interconnection,
billing, directory listing, number portability, provisioning, network
signaling and many other issues. Prior to the passage of the Telecom Act, MFS
had reached such agreements with several large telecommunications companies.
The Telecom Act mandates that more comprehensive and, from MFS' perspective,
generally more favorable, interconnection agreements be negotiated between
competitors and incumbent local phone companies. The Telecom Act further
conditions Bell Operating Company entry into long distance service within
their existing service territory on, among other things, successful completion
of such negotiations or failing successful negotiations, an arbitrated
arrangement mandated by state regulators.
 
  The Company currently offers CLEC services in 14 metropolitan areas in seven
states. In addition, the Company has, for some time, combined long distance
service with its local offerings and intends to continue to offer a
comprehensive set of local and long distance services in additional
geographical markets as it is able to negotiate agreements successfully with
incumbent local phone companies.
 
  The Company refers to itself as an ICP to distinguish itself from CLECs that
do not offer long distance service.
 
 Internet
 
  The Internet is a global collection of computer networks cooperating to
enable commercial organizations, educational institutions, government agencies
and individuals to communicate electronically, access and share information
and conduct business. The Internet originated with the ARPAnet, a restricted
network started in 1969 by the United States Department of Defense Advanced
Research Projects Agency to provide efficient and reliable long-distance data
communications among the disparate computer systems used by government funded
researchers and organizations. Unlike the public and private
telecommunications networks that are managed by businesses, government
agencies and other entities, the Internet is a cooperative interconnection of
many such public and private networks. The networks that comprise the Internet
are connected in a variety of ways, including by the public switched telephone
network and by high speed, dedicated leased lines. Communications on the
Internet are enabled by TCP/IP, an inter-networking standard that enables
communication across the Internet regardless of the hardware and software
used.
 
  Recent technological advances, including increases in microprocessor speed
and the development of easy-to-use graphical user interfaces, combined with
cultural and business changes, have led to the Internet being integrated into
the daily activities of individuals and the operations and strategies of
commercial organizations. For example, a growing number of employees within
organizations have access to corporate networks, thereby increasing the amount
of electronic communication both within and between organizations. In
addition, the rapid growth of the installed base of home PCs equipped with
communication devices such as modems has created the ability to communicate
electronically from home. These technological, cultural and business trends
have led to an increase in the number of on-line services and Internet access
providers. More recently, the development of World Wide Web technology and
associated easy-to-use software has made the Internet easier to navigate and
more accessible to a larger number of users and for a broader range of
applications.
 
  While there has been significant media interest in use of the Internet by
consumers, the Company believes business and professional organizations
currently represent a more significant percentage of Internet use. These
organizations increasingly are recognizing that the Internet can enhance
communications, both among their geographically distributed locations and
employees, and with their business partners and customers. In addition,
businesses are realizing that the Internet can enable many applications which
were previously unavailable or cost-prohibited. For example, small and
 
                                      54
<PAGE>
 
medium-sized businesses can establish and maintain a global presence, and
market and distribute their products and services electronically.
 
  Despite growing interest in the many commercial uses of the Internet, many
businesses have been deterred from purchasing Internet access services for a
number of reasons, including inconsistent quality of service, a lack of wide
availability of cost-effective high speed options, a limited number of local
access points for corporate users, inability to integrate business
applications on the Internet, the need to deal with multiple and frequently
incompatible vendors, inadequate protection of the confidentiality of stored
data and other information moving across the Internet and a lack of tools to
simplify Internet access and use.
 
COMMUNICATIONS SERVICES MARKET
 
  The communications services market can be divided into two basic categories:
traditional, circuit switched and dedicated voice oriented services; and
packet switched services compatible with Internet standards. Traditional,
circuit switched and dedicated voice oriented services in the United States
can be further divided into long distance services and local exchange
services.
 
 Traditional Telecommunications Service Market
 
  Long Distance Services. A long distance telephone call can be envisioned as
consisting of three segments. Starting with the originating customer, the call
generally travels along a local exchange network to a long distance carrier's
POP. At the POP, the call is combined with other calls and sent along a long
distance network to a POP on the terminating customer's local network. The
call is then sent from this POP along a local exchange network to the
terminating customer. Long distance carriers generally provide only the
connection between the two local exchange networks and pay access charges to
LECs for originating and terminating calls.
 
  The following diagram illustrates the typical long distance call.
 
                               [INSERT DIAGRAM]
 
  The long distance service market has experienced increased competition since
the late 1970s, and new entrants have obtained a combined market share of
approximately 40 percent. Certain services provided by the Company through MFS
Intelenet and MFS Datanet entail the resale of long distance switched and
private line service.
 
  Local Exchange Services. A local call is one that by definition does not
require the services of a long distance carrier and does not cross exchange
boundaries. In general, the LECs connect end user customers within an exchange
and also provide the local portion of most long distance calls, and LECs
generate revenue from end user customers and from long distance carriers,
which must pay access charges for the use of local exchange networks. Before
the entrance of CAPs, the local exchange markets operated with virtually no
competition.
 
 
                                      55
<PAGE>
 
  The market for local exchange services consists of a number of distinct
service components. These service components are defined by specific
regulatory tariff classifications including: (i) local network services, which
generally include basic dial tone charges and private line services; (ii)
network access services, which consist of access charges received by LECs from
long distance carriers for the local portion of long distance telephone calls;
(iii) long distance network services, which include the variable portion of
charges received by LECs for intraLATA long distance calls; and (iv)
additional value added services such as caller identification, voice mail and
call waiting.
 
  Prior to the passage of the Telecom Act, the Company could compete
effectively for only certain of the service components listed in the preceding
paragraph and in only a limited number of states. However, the Company
currently believes that, over time, it will be able to offer a comprehensive
range of local and long distance services in any area it chooses to serve.
 
  The following diagram illustrates an ICP local and long distance network:
 
 
                               [INSERT DIAGRAM]
 
 
  International. Historically, the European telecommunications environment was
a closed market consisting almost exclusively of government owned and operated
PTTs. Recently, however, the regulatory framework in Europe has begun to
change and European countries have begun to privatize their telecommunication
carriers. The European Union in 1990 issued a directive to its member states
to liberalize telecommunication services other than switched voice services by
opening their monopoly markets. The European Union further proposed that by
July 1996 most member states allow facilities based competition for
liberalized services.
 
  Internet Services. The Company believes that the Internet services market is
growing very rapidly. However, the Company is unaware of any definitive
estimate of market size and is unable to make an estimate.
 
                                      56

<PAGE>
 
  Network Systems Integration. The network systems integration market consists
of the design, engineering, development and installation of communications
networks and systems for a wide variety of end users, including
telecommunications companies and other business and government users. The
network systems integration market is an early stage, rapidly growing market
due to technological developments, primarily in fiber optic and electronics,
which allow for more efficient transmission of data, voice and video traffic.
While the Company believes that network systems integration provides
significant opportunities, the Company is unable to estimate with any degree
of certainty the size of the potential market.
 
INTERNATIONAL NETWORK PLATFORM
 
  Communications networks can be divided into discrete categories by function,
with relatively well defined interfaces between each function. The
transmission function consists of physical media such as fiber optic cable
coupled with transmission equipment to convert voice, data or video traffic to
an appropriate signal (e.g. optical signals in the case of fiber optics) for
transmission along the physical media. At the terminus of the transmission
path, the transmission equipment converts the signal back to its original
form. The transmission function (also sometimes referred to as the
transmission network) can be used to connect users in a point-to-point
dedicated fashion (called a dedicated circuit or private line) or to connect
switches.
 
  Generically, the switching function is used to avoid the cost of connecting
every communication user to every other user with dedicated circuits. By
connecting each user to a device which, on demand, ensures that information is
switched or routed to the intended recipient, each user need only be served by
a single transmission path connected to the switching device.
 
  In the U.S. and globally, communications users are connected by a relatively
uniform and standard transmission platform consisting of interconnected
transmission networks owned by a variety of entities, including MFS. However,
two different types of switching infrastructures have been relatively widely
deployed, the traditional voice oriented circuit switched network and newer
packet switched networks such as the Internet.
 
  Transmission Network. The Company provides communications services by
utilizing a transmission network which consists of Company-owned facilities
and capacity leased from other carriers both in the United States and
internationally. The Company-owned portion of the transmission network
consists of metropolitan area networks of fiber optic cables, transmission
equipment and associated wiring and equipment. The Company's backbone
transmission equipment is generally based on a standard called SONET in the
United States or a comparable standard called Synchronous Digital Hierarchy
(SDH) in networks deployed internationally.
 
  The fiber optic cable utilized in the Company's networks typically contains
from 12 to 144 optical fiber strands, each of which is capable of providing
multiple telecommunications channels or "circuits". Depending on transmission
electronics, a single pair of glass fibers on the Company's network currently
can transmit, utilizing available SONET and SDH transmission equipment, up to
129,024 simultaneous two way voice conversations. These transmission protocols
can also be used to carry data and video signals.
 
  A pair of copper wires generally can carry a maximum of 24 simultaneous
voice conversations. Although the LECs and foreign telecommunications carriers
have traditionally used copper wire in their networks, they currently are
deploying fiber optic cable to supplement or upgrade portions of their copper-
based networks, particularly in areas served by the Company. The Company
expects that continuing developments in telecommunications equipment will
increase the capacity of each optical fiber, thereby providing even greater
capacity at relatively low incremental cost.
 
 
                                      57

<PAGE>
 
  Customer building locations are connected to the Company's transmission
networks by extensions to one of a number of physical rings of fiber optic
cable, which originate and terminate at the Company's central nodes. Signals
are generally sent through the network simultaneously on both primary and
alternate protection paths. Most buildings served have a discrete Company
presence (referred to as a "remote hub") located in the building. Within each
building, Company-owned internal wiring generally connects the remote hub to
the customer premises. Customer equipment is connected to Company-provided
electronic equipment generally located in the remote hub where customer
transmissions are digitized, combined and converted to an optical signal. The
traffic is then transmitted through the network to the Company's central node
where originating traffic can be reconfigured for routing to its ultimate
destination.
 
  The following table illustrates the growth of the Company's transmission
network.

  Circuit Switching Platform. Circuit switching is a relatively mature
technology which was originally developed to displace human operators who
manually connected users engaging in voice conversations. The connections are
made for the duration of the call and dedicate a fixed amount of capacity,
whether that capacity is utilized or not.
 
  The amount of capacity dedicated is 4000 hertz or, if digitally encoded,
64,000 kbps. In recent times, circuit switched connections have been utilized
for a wide variety of applications beyond voice calling, including fax, data
transmission and Internet access. The vast majority of telecommunications
services revenues is derived from circuit switched traffic.
 
  The Company has currently deployed 18 circuit switches, 16 of which are
combined local and long distance switches and two of which are international
gateway switches which enable voice grade connections between users in
countries utilizing different technical standards.
 
  The Company intends to deploy a total of approximately 50 combined local and
long distance switches in the United States. Deployment of circuit switches in
other countries depends on regulatory developments which the Company is unable
to predict with any precision at this time.
 
  Packet Switching Platform. Packet switching is, relative to circuit
switching, a fairly new technology. The most widely implemented version of
packet switching, which employs a standard called Transmission Control
Protocol/Internet Protocol (TCP/IP), is found in the Internet. Under this
standard, voice, data, or video information is divided into pieces and
additional information, including the network address of the recipient, is
attached. These strings of information are called "packets" and are of
variable length depending on the type of information transmitted. Packets are
sent from originator to recipient over the same kind of transmission network
used by circuit switching. However,
 
                                      58
<PAGE>
 
unlike this older standard, packet switching does not dedicate capacity to
each connection between end users. Instead, packet switching shares available
transmission capacity among multiple end users and end user packets are
intermixed within that capacity. Originating transmission paths are connected
to devices called routers which read the address attached to each packet.
Packets are then sent along on an available, uncongested transmission path in
the general direction of the recipient, in accordance with "rules" programmed
into routers. Thus, individual packets, even though part of the same
communications to the same user, may take different paths through the
transmission network.
 
  The Company believes that packet switching has certain advantages over
circuit switching including: the ability to mix voice, data and video; the
ability to transmit information which requires higher capacity connections
than available through the traditional circuit switched network; and the
potential to transmit information at lower costs.
 
  The following table illustrates the relative cost advantage of the IP Packet
switched Internet over other alternatives for certain business data
transmissions.

  While the costs presented above are shown with specificity, there are a
large number of factors which influence actual transmission costs. Among the
factors which could influence one or more of the above costs are the form of
the transmitted data, the amount of time required to transmit the data, the
type and cost of hardware utilized, software costs, local access charges, one-
time setup charges, monthly service charges, corporate discounts and other
related charges or discounts in effect at any given time. In addition, there
are other inherent differences among the alternatives, such as the form of the
information transmitted, reliability of transmission, and security. These
factors reduce the comparability of the alternatives and may result in
transmission costs which vary significantly from those noted above.     
 
  While the Company believes TCP/IP packet switching has certain advantages
over circuit switching, TCP/IP based networks currently have a number of
relative disadvantages including lack of quality of service guarantees,
potential security issues and difficulty in transmitting information such as
voice or video which must arrive at the recipient with little delay through
the network and with individual packets in order.

 UUNET's Network Infrastructure
 
  UUNET's network infrastructure is based on its own 45 Mbps, DS-3 leased
line, Frame Relay-based network of Cascade Communications Corporation
("Cascade") switches supporting Cisco Systems, Inc. ("Cisco") 7000 routers.
This network infrastructure enables customers to access the Internet through
dedicated lines or by placing a local telephone call (dial-up) through a modem
to the nearest UUNET POP. Once connected, the customer's traffic is routed
through UUNET's network infrastructure to the desired Internet location,
whether on UUNET's network or elsewhere on the Internet.
 
  UUNET continues to upgrade its infrastructure in response to the increases
in the number of customers purchasing UUNET's Internet access services,
particularly UUNET's high-speed T-1 and T-3 access options. The Company
believes that this network infrastructure provides the higher bandwidth,
increased throughput and the reliability, capacity and the geographic coverage
that the Company believes is required by businesses and professionals at a
lower per unit cost than its previous infrastructure.

network infrastructure, following the acquisition of UUNET PIPEX, a 40 percent
interest in EUnet Germany, and a 51 percent interest in UUNET Canada, allowed
local access to users at 543 POPs, including 288 outside of the United States.

TELECOMMUNICATIONS SERVICES
 
  Unlike the BOCs and other large LECs which were organized geographically in
response to the regulatory environment that existed before the Divestiture,
the Company is organized to take advantage of ongoing technological,
competitive and regulatory changes. As a part of the Company's strategy to be
the primary provider of telecommunications services to business and government
customers, MFS has developed a corporate structure which is organized around
specific market segments.

 The MFS Telecom Companies
 
  Large users of telecommunications services typically have experienced staff
to help meet their growing need for data and video transmission in addition to
their traditional need for local and long distance voice service. Through MFS
Telecom, the Company provides dedicated special access and local private line
services to large users over fiber optic networks. MFS Telecom offers local
switched services to certain of its customers.
 
  The Company organized MFS Datanet to provide services to data intensive
users that the Company believed were inadequately served by traditional
telecommunications networks. The Company provides various data transmission
services at a variety of LAN speeds and protocols, including high speed LAN
interconnect services such as Frame Relay, Ethernet, Token Ring and FDDI
utilizing the Company's ATM network. The Company also provides a variety of
lower speed data services.
 
 The MFS Intelenet Companies
 
  Small and medium sized businesses generally do not employ in-house
telecommunications specialists to manage their facilities and negotiate local
and long distance services with a number of different vendors. Through the MFS
Intelenet Companies, the Company provides a single source for integrated local
and long distance telecommunications services. Its customers enjoy a level of
convenience which has been largely unavailable to them since the Divestiture,
with a single point of contact, a single bill and rates which are frequently
at a discount from the combined rates charged by the BOCs and the long
distance carriers. In addition, the Company provides a wide range of value-
added services, including calling card, 800 number, voice mail, customized
billing and management reporting.
 
 MFS International
 
  MFS International provides international communications services designed to
better serve MFS' existing customer base of multinational companies and to
appeal to other business and government users abroad.
 
  In London and Stockholm, MFS International provides a full range of voice,
data and video communications to businesses in greater London and Stockholm
either over its own networks or by reselling services of incumbent carriers.
MFS International also provides a growing range of communications services in
certain other key European business centers and anticipates that it will
continue to develop new markets throughout Europe as anticipated regulatory
liberalization proceeds.
 
  MFS International provides international private line and enhanced services
to end users and is authorized by the FCC to provide the full range of
switched and private line voice and data services originating and terminating
in the United States.
 
  In 1995, MFS International: (i) obtained government authorizations to
construct and operate the first alternative metropolitan area fiber network in
Frankfurt; (ii) was granted a full national and international operating
license in Sweden; (iii) entered into an agreement with Telecom Finland to
interconnect the two companies' data networks; (iv) received a license to
construct and operate the first alternative metropolitan area fiber optic
network in Paris; and (v) commenced offering non-facilities based services in
Zurich. The construction of the Frankfurt network has been completed, and
data, private line voice and closed user group switched voice service is now
being offered to business customers in that city. The Company has been
offering non-facilities based services in Paris since 1995. The installation
of a network in Paris commenced in the first quarter of 1996 and service
commenced in May 1996. In 1996, MFS began offering liberalized international
resale services in Hong Kong.

 Global Network Services
 
  MFS Global Network Services manages the development and operations of MFS'
networks. MFS Global Network Services contracts with MFS Network Technologies,
which engineers and manages the construction of the fiber optic networks. As
each portion of a network is completed, MFS Global Network Services manages
the operation of the network.
 
INTERNET-RELATED SERVICES
 
  The Company plays a major role in making the Internet available to users
through sales of dedicated circuits for local access and ATM-based backbone
service to Internet service providers. MFS Datanet is also one of several
companies that manage the operation of Network Access Points ("NAPs"), through
which significant amounts of traffic on the Internet pass. MFS developed and
manages NAPs that are known as MAE East in Washington, D.C., MAE West in San
Jose, California and MAE Chicago in Chicago, Illinois. Additional NAPs are
under development.
 
  UUNET provides a comprehensive range of Internet access options,
applications and consulting services tailored to meet the needs of businesses
and professionals. UUNET's solution has been designed to address many of the
issues that have discouraged businesses and professionals from using the
Internet in the past. The UUNET solution is based upon UUNET's high
performance domestic and international network infrastructure designed
specifically to provide reliable Internet connectivity to businesses with
demanding throughput requirements.
 
  As of March 31, 1996, UUNET's primary Internet access options included (i)
dedicated Internet access, with service ranging from high speed services (T-1
and above) for very large businesses with demanding throughput requirements to
medium speed service via dedicated lines or frame-relay for small to mid-size
businesses, and (ii) dial-up Internet access. These Internet access options
are sold in the United States and in many foreign countries, and are also
offered under varying names and different prices in the United Kingdom and
Germany.
 
  UUNET also makes available to customers a variety of products and services,
including Web server hosting and content development services, client software
and security products and training, all of which can be integrated by UUNET
through its network integration and consulting services. UUNET enables
Internet users to purchase access, applications and services, including
integration services, through a single source. UUNET's products and services
are supported by a technical staff that is highly experienced in Internet
operations and services. UUNET's network operations center monitors traffic
across UUNET's network 24 hours per day, seven days per week.
 
  UUNET provides additional related products and services that are often
required by UUNET's business customers, including: hardware, such as network
equipment from Cisco and Ascend and Instant Internet from Performance
Technology; digital modems and cabling; software, such as Chameleon from
NetManage, Internet in a Box from Spry (a division of CompuServe); tutorials,
such as seminars to educate current and potential customers about Internet
access options and applications available from UUNET; and various consulting
services, such as integrating various Internet access services and
applications.
 
  The Company's objective is to be the leading supplier worldwide to
businesses and professionals of complete communications solutions using
Internet-related technologies. The acquisition of UUNET is a significant step
toward the achievement of this objective. Following consummation of the
Merger, the Company intends to focus on five key elements: (i) expanding
operations worldwide; (ii) expanding high performance infrastructure; (iii)
increasing focused marketing efforts; (iv) expanding and integrating product
and service offerings; and (v) building and leveraging relationships with
strategic partners.

 International Expansion Plan
 
  UUNET initiated a major international expansion in 1995. UUNET has
established international gateway hubs in 14 countries (Australia, Belgium,
Canada, France, Germany, Hong Kong, Italy, Japan, The Netherlands, Singapore,
Spain, Sweden, Switzerland, the United Kingdom), which provide service in
seven cities in Canada (Calgary, Edmonton, Montreal, Ottawa, Toronto,
Vancouver, Winnipeg); nine cities in Europe (Amsterdam, Brussels, Cologne,
London, Madrid, Milan, Paris, Stockholm, Zurich); three cities in Asia (Hong
Kong, Singapore, Tokyo); and in Sydney, Australia. These hubs concentrate and
route data traffic from UUNET's dedicated and dial-up customers as well as
from the dial-up customers of The Microsoft Network. Microsoft has agreed to
pay an operating fee and a management fee in connection with these hubs. See
"--Microsoft Relationship."
   
  The rate of growth of Internet use worldwide has accelerated in the past
year. In order to take advantage of worldwide growth of Internet use and
accelerate UUNET's international expansion, UUNET significantly expanded its
operations outside the United States during 1995. In November 1995, UUNET
acquired UUNET PIPEX, the largest Internet access provider in the United
Kingdom. In February 1996, UUNET completed the acquisition of 40 percent of
the shares of EUnet Germany and, in April 1996, UUNET acquired an additional
ownership interest in UUNET Canada, bringing its ownership to 51%. UUNET
intends to accelerate its geographic expansion and expects to pursue various
partnering arrangements to facilitate this expansion, including joint
ventures, acquisitions and commercial arrangements.     
 
  The Company intends to accelerate UUNET's international expansion begun in
1995 by pursuing several avenues, including acquiring other Internet service
providers and complementary businesses and technologies in various target
countries.
 
 Microsoft Relationship
 
  In December 1994, UUNET and Microsoft entered into a strategic relationship
for the development, operation and maintenance of a large-scale high speed
dial-up and ISDN TCP/IP access network which is the primary Internet dial-up
network and infrastructure for Microsoft, including The Microsoft Network.
This relationship provides UUNET with the opportunity to accelerate the
expansion of the geographic coverage and capacity of its network
infrastructure domestically and internationally. The access network is an
integral part of the dial-up and ISDN component of UUNET's upgraded network
infrastructure. As a result, the geographic coverage of the access network is
the same as that of UUNET's overall network infrastructure.
 
  Microsoft and UUNET have agreed upon the schedule for deployment of the
network, and Microsoft is obligated to pay an operating fee equal to the cost
of constructing, maintaining and operating the U.S. and Canadian dial-up
network and the first 14 international gateway hubs and to pay a management
fee regardless of any delay by Microsoft in its use of the network. The terms
of construction, maintenance and operation (including the allocation of costs
and the payment of fees) of international gateway hubs beyond the initial 14
such hubs are subject to future agreement between Microsoft and UUNET. UUNET
expects that the terms of any funding or revenues from Microsoft relating to
additional international hubs, if any, will be different from those of the
Microsoft Agreement. In addition, UUNET and Microsoft have an understanding
that providers of Internet access services (such as the PTTs) will begin to
bear certain of the costs of the 14 international gateway hubs. As this
begins, Microsoft's share of such costs will decrease, and UUNET will become
more dependent upon such providers and other customers for revenues to support
such costs. Microsoft continues to evolve its international strategy for The
Microsoft Network, and its final strategy may differ materially from that
originally anticipated. Although UUNET is Microsoft's primary Internet access
provider, there can be no assurance that Microsoft will obtain additional
Internet network infrastructure or capacity it may require from UUNET, other
than that specified in the Microsoft Agreement. Microsoft has announced a
 
                                      64
<PAGE>
 
relationship with MCI under which MCI will resell The Microsoft Network,
Microsoft's Internet Explorer Web browser software and other Microsoft
Internet-related software. Although the terms of the relationship have not
been fully disclosed, this relationship with MCI may allow access to The
Microsoft Network through MCI's dial-up network. Further, Microsoft is
developing relationships with other Internet service providers to resell The
Microsoft Network and the Internet Explorer. As originally planned, Microsoft
is developing relationships with foreign and domestic telecommunications
companies and Internet access providers to resell access to The Microsoft
Network. If Microsoft fully develops these resale relationships, UUNET may not
receive revenues from Microsoft beyond Microsoft's guaranteed minimum
payments. Any failure of such revenues to increase could have a material
adverse effect on UUNET's business, financial condition or results of
operations.
 
  As part of its relationship with UUNET, Microsoft made an equity investment
in UUNET, which currently represents approximately 13 percent of the
outstanding UUNET Common Stock. Microsoft also agreed to lend UUNET up to
$26.0 million to finance the purchase of equipment used in construction of the
network; $3.2 million of this amount remained available for borrowing as of
March 31, 1996. UUNET owns the equipment and Microsoft retains a security
interest in the network equipment and in UUNET's revenues from the network.
Depending upon UUNET's success in meeting certain operational criteria agreed
upon between UUNET and Microsoft, the management fee payable by Microsoft to
UUNET varies between six percent and ten percent of the operating costs to be
funded by Microsoft (exclusive of interest on the loan) and may be temporarily
suspended in the event of a sustained operational failure of the network.
Revenues from Microsoft accounted for approximately 20%, 34% and 37% of
UUNET's consolidated revenues for the year ended December 31, 1995 and the
quarters ended December 31, 1995 and March 31, 1996, respectively.
 
  The network-related agreement with Microsoft has an initial term ending in
March 2000, renewable by Microsoft for an additional five years. After
September 1996, Microsoft may terminate the agreement if UUNET breaches
certain material terms of the agreement and is unable to cure, thereby causing
a sustained operational failure of the dial-up access network and under
certain other circumstances. The terms of the agreement with Microsoft
restrict UUNET's ability, prior to March 1997, to enter into similar
agreements for the deployment of other large-scale dial-up networks with,
among others, on-line service providers intending to deploy a domestic or
international on-line service. The Company does not believe that the effect
those restrictions will have a material adverse effect on UUNET's business as
UUNET plans to focus on the domestic and international deployment, operation
and expansion of the Microsoft dial-up access network and UUNET's core
business (the provision of Internet access options, applications and
consulting services).
 
CUSTOMERS AND MARKETING
 
 Telecommunications Services
 
  The Company's marketing activities are directed toward business and
government customers. Sales and marketing activities are conducted by direct
sales and marketing forces in each business market and by national account
managers. In addition, the Company markets its services through
advertisements, trade journals, media relations, direct mail and participation
in trade conferences. The Company's customers include large corporations,
financial services companies, governmental departments and agencies, and
academic, scientific and other major institutions, as well as medium and small
businesses and long distance carriers.
 
  The Company's customers typically enter into service agreements of at least
twelve months which usually convert into month-to-month agreements at the end
of the term. Certain customers have entered into longer term agreements.
Customer billings are divided into recurring and non-recurring charges
(including one-time installation charges).
 
 
                                      65
<PAGE>
 
 Internet-Related Services
 
  UUNET's customers are businesses and professionals in many lines of
business. UUNET estimates that its customer base included over 22,000 business
and professional accounts as of March 31, 1996. In 1995, no customer other
than Microsoft accounted for more than one percent of UUNET's total revenues.
See " -- Microsoft Relationship."
 
  Historically, UUNET has sold its Internet access and applications products
and services primarily through its direct telephone sales force. Call activity
is generated in response to a variety of promotional programs, including
advertising in general business and specialty periodicals, participation in
industry shows and public relations. The sales organization also includes the
installation group which is responsible for support for the first 30 days
after installation. In addition, UUNET engages in local promotional programs
to support newly opened service locations.
 
  After the Merger, the Company intends to utilize its direct sales force to
expand the marketing of UUNET's Internet services and associated products.
 
 Network Systems Integration Services
 
  MFS Network Technologies' third party customers include major local and long
distance telecommunications carriers, public utilities, cable television
operators, agencies of federal, state and local government and large
corporations. The Company's network systems integration segment revenues are
and may continue to be dependent upon a small number of large projects.
Accordingly, these revenues are likely to vary significantly from period to
period.
 
COMPETITION
 
 Telecommunications Services
 
  Virtually all markets for telecommunications services are extremely
competitive. MFS expects that competition will intensify in the future. In
each of its markets, MFS faces significant competition from larger, better
financed incumbent providers. MFS competes domestically and internationally
with incumbent carriers, which have historically dominated their local
telecommunications markets. The incumbent LECs have established relationships
with their customers and provide those customers with various transmission and
switching services that the Company, in many cases, is not currently allowed
by regulators to offer or only recently began to offer such services. The
Company has sought and will continue to seek to achieve regulatory parity with
the LECs in order to provide local telecommunications services, including
reasonable and nondiscriminatory access to equipment rooms, rights-of-way and
comparable treatment with respect to the imposition of franchise fees. See "--
Government Regulation." Incumbent LECs, however, presently have numerous
advantages as a result of their historical monopoly of the local exchange
market. The Company continues to challenge, before federal and state
regulators, many inequities which exist because of the LECs' historical
status. The Company believes the Telecom Act may enhance its ability to
achieve parity with the LECs over time. However, the Telecom Act may also
increase the degree of competition the Company experiences.
 
  A continuing trend toward business combinations and alliances in the
telecommunications industry may create significant new competitors to the
Company. Many of the Company's existing and potential competitors have
financial, personnel and other resources significantly greater than those of
the Company.
 
  The Company also faces competition in most markets in which it operates from
one or more CAPs operating fiber optic networks, in many cases in conjunction
with the local cable television operator. AT&T, MCI and Sprint have each
indicated its intention to offer local telecommunication services in major
U.S. markets using their own facilities or by resale of the LECs, or other
providers' services. In
 
                                      66
<PAGE>
 
addition to the LECs, CAPs and CLECs, competitors potentially capable of
offering private line, special access and switched services include cable
television companies, electric utilities, long distance carriers, microwave
carriers, wireless telephone system operators and private networks built by
large end users.
 
  Under the Telecom Act and ensuing federal and state regulatory initiatives,
barriers to local exchange competition are being removed. Adoption of the co-
carrier checklist and introduction of facilities-based local competition,
however, is required before the BOCs may provide in-region interexchange long
distance services. The BOCs are currently allowed to offer certain
"incidental" long distance services in-region and to offer out-of-region long
distance services. Once the BOCs are allowed to offer widespread in-region
long distance services, both they and AT&T, MCI and Sprint will be in a
position to offer single source local and long distance services similar to
that being offered by MFS. The Company expects that the increased competition
made possible by regulatory reform will result in certain pricing and margin
pressures in the domestic telecommunications services business.
 
  Because it believes it currently has certain advantages relating to quality
control, network maintenance and cost savings resulting from its use of the
Company's existing fiber optic network, MFS believes that it may enjoy certain
advantages with respect to certain of its competitors. There is no guarantee
that MFS will be able to maintain these advantages.
 
  MFS Intelenet competes with the LECs, certain CAPs and CLECs, equipment
vendors and installers, long distance providers and telecommunications
management companies. Although MFS believes that no single competitor offers
integrated telecommunications services nationwide over its own local
facilities exclusively for business customers, each of these types of
competitors currently provides some or all of the services MFS Intelenet
offers or plans to offer. Because it believes it has certain advantages
relative to quality control, network maintenance and cost savings resulting
from its use of the Company's existing fiber optic networks, MFS believes that
MFS may enjoy certain advantages with respect to certain of its competitors.
 
  The Company believes that the Telecom Act, as well as a recent series of
transactions and proposed transactions between telephone companies and cable
companies, increases the likelihood that barriers to local exchange
competition will be removed. The introduction of such competition, however,
also increases the possibility that BOCs will be authorized to provide
interexchange services. If BOCs are permitted to provide such services, they
will be in a position to offer single source service similar to that being
offered by MFS Intelenet.
 
  Although the Company believes that no single competitor currently offers
high-speed end-to-end interstate LAN interconnection services over its own
local facilities, potential competitors for these services include stand-alone
data transmission entities, as well as LECs, other CAPs and cable television
companies.
 
 Internet Related Services
 
  The market for data communications services, including Internet access and
on-line services, is extremely competitive. In the case of non-facilities
based providers, there are no substantial barriers to entry, and the Company
expects that competition will intensify in the future. The Company believes
that its ability to compete successfully depends on a number of factors,
including market presence; the ability to execute a strategy of rapid
expansion; the capacity, reliability and security of its network
infrastructures; ease of access to and navigation of the Internet; the pricing
policies of its competitors and suppliers; the timing of the introduction of
new products and services by the Company and its competitors; the Company's
ability to support industry standards; and industry and general economic
trends. The Company's success in this market will depend heavily upon its
ability to provide high quality Internet connectivity and value added Internet
services at competitive prices.
 
                                      67
<PAGE>
 
  The Company's current and potential U.S.-based competitors generally may be
divided into the following three groups: (1) telecommunications companies,
such as AT&T, MCI, Sprint, WorldCom, BOCs and @Home; (2) other Internet access
providers, such as BBN Corporation ("BBN"), NETCOM On-Line Communication
Services, Inc., PSINet Inc. ("PSI"), and other national and regional
providers; and (3) on-line services providers, such as America Online Inc.
("America Online"), CompuServe Corporation ("CompuServe"), Intuit Inc.,
Microsoft, and Prodigy. Certain of these competitors have greater market
presence, engineering and marketing capabilities, and financial, technological
and personnel resources than those available to the Company. As a result, they
may be able to develop and expand their communications and network
infrastructures more quickly, adapt more swiftly to new or emerging
technologies and changes in customer requirements, take advantage of
acquisition and other opportunities more readily, and devote greater resources
to the marketing and sale of their services than can the Company.
 
  The Company expects that all of the major on-line services providers will
expand their current services to compete fully in the Internet connectivity
market. In addition, the Company believes that new competitors, including
large computer hardware, software, media and other technology and
telecommunications companies, will enter the Internet connectivity market,
resulting in even greater competition for the Company. Certain companies,
including America Online, AT&T, BBN and PSI, have obtained or expanded their
Internet access products and services as a result of acquisitions and
strategic investments. Such acquisitions may permit the Company's competitors
to devote greater resources to the development and marketing of existing
competitive products and services. The Company expects these acquisitions and
strategic investments to increase, thus creating new competitors to MFS and
UUNET. In addition, the ability of some of the Company's competitors to bundle
other services and products with Internet connectivity services, such as the
Internet service offerings recently announced by AT&T and MCI, could place the
Company at a competitive disadvantage.
 
  As a result of increased competition in the industry, the Company expects to
continue to encounter significant pricing pressure, which in turn could result
in significant reductions in the average selling price of the Company's
Internet-based services. For example, certain of the Company's competitors,
including AT&T and MCI, provide customers with low priced or free Internet
access services in connection with the purchase of telephone or other
communications services, significantly increasing price pressures on the
Company. UUNET has in the past reduced prices on certain of its Internet
access options and the Company may do so in the future. There can be no
assurance that the Company will be able to offset the effects of any such
price reductions through an increase in the number of its customers, higher
revenue from enhanced services, cost reductions or otherwise. In addition, the
Company believes that the data communications business, and in particular
Internet access and on-line services businesses, are likely to encounter
consolidation in the near future, which could result in increased price and
other competition in the industry. Increased price or other competition could
result in erosion of the Company's market share and could have a material
adverse effect on the Company's business, financial condition and results of
operations. There can be no assurance that the Company will have the financial
resources, technical expertise, marketing and support capabilities or
expansion and acquisition possibilities to continue to compete successfully.
 
 Network Systems Integration
 
  MFS Network Technologies' primary network systems integration competitors
are the BOCs, long distance carriers, equipment manufacturers and major
independent telephone companies. In certain circumstances, MFS Network
Technologies may also compete with regional and local systems integration and
construction firms for integration and installation projects. In the automatic
vehicle identification market, MFS Network Technologies competes with specific
manufacturers and several of the aerospace defense contractors that have
indicated an intention to shift to commercial markets.
 
 
                                      68
<PAGE>
 
 International Competition
 
  The three international markets in which the Company competes are
international services from the United States, international services from
certain countries in continental Europe and Hong Kong and certain domestic
services within the United Kingdom, France, Germany and Sweden. The Company
offers private line, high-speed LAN interconnect data, and voice services in
each of these markets, subject to varying governmental authorizations.
 
  The Company faces competition in international service originating in the
United States from, among others, AT&T, MCI, Sprint and WorldCom. These
companies own significant international cable capacity and have established
operating agreements with governmental and private telecommunications
providers in Europe, Asia and elsewhere which reduces their cost to provide
service. Each of these companies is larger and better financed than the
Company. In international markets, MFS competes with the incumbent
telecommunications carrier, which generally offers both local and long
distance service and benefits from its history as an incumbent provider.
 
  The United Kingdom allows for direct facilities-based competition for
domestic services. The Company competes in the United Kingdom with British
Telecom ("BT") and other facilities-based licensed carriers. Currently, there
are fifteen direct competitors and forty-five licensed applicants in the
United Kingdom. These numbers may expand if the United Kingdom allows carriers
in addition to BT and Mercury Communications Limited ("Mercury") to provide
facilities based international services, which it may do in July 1996. Many
European countries are expected to allow facilities based competition for
liberalized services later this year. At this time it is unclear under what
terms and conditions these services will be allowed, if at all.
 
  In continental Europe the PTTs, and other incumbent telecommunications
providers, generally retain their monopoly on public services. While the
Company operates on a limited basis as a facilities-based carrier in
Frankfurt, Germany and Paris, France and received a facilities based operating
license to service Stockholm, Sweden. With these limited exceptions, MFS must
compete with the monopoly PTTs based on resale of their private line and voice
services. Other companies which offer service on this resale basis include
AT&T, MCI, BT and Sprint.
 
  As the Company expands its Internet-related services internationally, the
Company will be forced to compete with and buy services from government owned
or subsidized telecommunications providers, some of which may enjoy an
absolute monopoly on telecommunications service essential to the Company's
business. There can be no assurance that the Company will be able to purchase
such services at a reasonable price or at all. For example, in the United
Kingdom, the Company competes directly with: (1) telecommunications companies,
such as BT, Mercury and others; (2) other Internet access providers, such as
Demon Internet Limited ("Demon") and EUnet; and (3) on-line services
providers, such as CompuServe, America Online/Bertelsmann, Microsoft and AT&T.
 
  In addition to the risks associated with the Company's previously described
competitors, these foreign competitors may possess a better understanding of
their local markets and may have better working relationships with local
telecommunications companies. There can be no assurance that the Company can
obtain similar levels of local knowledge and failure to obtain that knowledge
could place the Company at a serious competitive disadvantage.
 
GOVERNMENT REGULATION
 
  MFS is subject to varying degrees of federal, state, local and international
regulation. In the United States, MFS is most heavily regulated by the states,
especially for the provision of local exchange services. MFS must be
separately certified in each state to offer local exchange services. No state,
however, subjects MFS to price cap or rate of return regulation, nor is MFS
currently required to obtain
 
                                      69
<PAGE>
 
FCC authorization for installation or operation of its network facilities used
for domestic sources. FCC approval is required, however, for the installation
and operation of its international facilities and services. Both the states
and the FCC have determined that non-dominant carriers, such as MFS, are
required to file interstate tariffs on an ongoing basis, setting forth MFS'
rates and operating procedures. Challenges to these tariffs by third parties
may cause MFS to incur substantial legal and administrative expenses. The FCC
has initiated a rulemaking to eliminate this requirement for all nondominant
carriers, such as the Company. In addition, MFS is subject to varying degrees
of regulation in the foreign jurisdictions in which it conducts operations
including authorization for the installation and operation of its network
facilities. Although the trend in federal, state and international regulation
appears to favor increased competition and reduced regulation, no assurance
can be given that changes in current or future regulations adopted by the FCC,
state or foreign regulations or legislative initiatives in the United States
and abroad would not have a material adverse effect on MFS.
 
  Legislation. On February 8, 1996, President Clinton signed into law the
Telecom Act, comprehensive federal telecommunications legislation affecting
all aspects of the telecommunications industry. The Telecom Act establishes a
national policy that promotes local exchange competition. At the heart of the
Telecom Act is the requirement that local and state barriers to entry into the
local exchange market be removed. The Telecom Act establishes uniform
standards under which the FCC and the state commissions are to implement local
competition and co-carrier arrangements in the local exchange market. The
Telecom Act also imposes significant obligations on the BOCs and other
incumbent local exchange carriers, including the obligation to interconnect
their networks with the networks of competitors. Each incumbent LEC would be
required not only to open its network but also to unbundle the network so
competitors may purchase only those portions of the network that they require.
The pricing of these unbundled network elements and services will determine
whether it is economically attractive to use these elements. Incumbent LECs
will be required to make available for resale to new entrants all services
they offer end user customers on a retail basis to non-telecommunications
carriers. The Telecom Act also imposes requirements on LECs, such as the
Company, to provide interconnections, reciprocal call termination, telephone
number portability and resale of its telecommunications services.
 
  The Telecom Act provides, among other things, that the BOCs and other
incumbent LECs satisfy a competitive checklist, providing MFS and other
competitors the services and facilities necessary to offer local switched
services. Under the Telecom Act, the FCC is directed to interpret and clarify
these terms. The FCC is currently engaged in rulemaking proceedings to
establish these arrangements, which will ultimately be implemented by the
state telecommunications or regulatory commissions. The FCC is scheduled to
adopt these rules later this year. The following table summarizes the key
factors of the legislatively mandated competitive checklist, often referred to
as "co-carrier status," being pursued by the Company with the FCC and with
state regulators and the anticipated effect of these factors on the Company's
ability to provide fully competitive services on an economically efficient and
technically feasible basis.

  The BOCs' incentive to comply with the Telecom Act's opening of the local
exchange market to competition derives from the Telecom Act's provisions
allowing the removal of the current ban on BOC provision of interLATA (local
access transport areas) toll service and equipment manufacturing. This ban
will only be removed after the BOC demonstrates to the FCC, in consultation
with the Department of Justice and the relevant state commissions, that the
BOC has met the requirements of the competitive checklist which details the
basic co-carrier requirements and the FCC concludes that BOC entry into long
distance is in the public interest. The BOC must also generally show that it
has entered into an approved interconnection agreement with at least one
unaffiliated, facilities-based competitor in some portion of a state before
offering long distance service in that jurisdiction.
 
  While state-by-state regulatory activity has to date brought co-carrier
arrangements or initiatives to various degrees of completion in approximately
25 states, the Telecom Act is intended to accelerate the process and create a
competitive environment in all markets, eliminating state and local statutory
and regulatory barriers to entry. This preemption of state laws barring local
competition and the relaxation of regulatory restraints should enhance the
Company's ability to expand its service offerings nationwide.
 
  The Company, as a facilities-based, multi-market competitive provider
already active in emerging co-carrier environments, is now given legislative
support to complement its co-carrier services in markets across the country.
In addition to providing the Company with a national framework to achieve co-
carrier status in local exchange markets, the Telecom Act permits MFS, as a
telecommunications carrier with less than 5% of nationwide prescribed access
lines, to continue to offer single source combined packages of local and long
distance services. AT&T, MCI and Sprint may not bundle in a BOC's territory
their local services resold from a BOC and long distance service until the BOC
is authorized to enter the interLATA long distance market or for three years,
whichever event occurs earlier.

  The Telecom Act, by removing barriers to entry into the local exchange
market and at the same time enabling multiple carriers to compete with the
Company in the provision of local and long distance services, ultimately
allowing the BOCs and large interexchange carriers to offer their own packages
of single source local/long distance services, substantially increases the
competition the Company will face.
 
  The Telecom Act also creates a new Federal-State Joint Board for the purpose
of making recommendations to the FCC regarding the implementation of a largely
revised universal service program. All telecommunications carriers, including
the Company, that provide interexchange services are required to contribute,
on an equitable and nondiscriminatory basis, to the preservation and
advancement of universal service pursuant to a specific and predictable
universal service mechanism to be established by the FCC. The Company is
unable to predict the final formula for universal service contribution and its
own level of contribution.
 
  The Telecom Act in some sections is self-executing, but in most cases the
FCC must issue regulations that identify specific requirements before the
Company and its competitors can proceed to implement the changes the Telecom
Act prescribes. The FCC already has commenced several of these rulemaking
proceedings. In addition, the Telecom Act retains the authority of individual
state utility commissions to impose their own regulation of local exchange
services so long as such regulation is not inconsistent with the requirements
of the Telecom Act. The Company is unable to predict the final form of such
regulation and its potential impact on the market.
 
  Federal Regulation. The Company maintains an active profile before federal
regulators and has initiated and participated in many significant proceedings
before the FCC, influencing the development of interstate telecommunications.
As a result of rulings announced in September 1992 and August 1993 (the
"Interconnection Decisions") by the FCC, the Company is able to offer
interstate special access and switched access transport services to virtually
every business and government end user in the metropolitan areas which the
Company elects without being directly connected to such customers. The
Interconnection Decisions enabled CAPs to compete for transport of switched
long distance calls between LEC central offices and long distance carrier
POPs. At the same time the LECs were granted greater pricing flexibility for
those services. Portions of the Interconnection Decisions are currently
subject to further review at the FCC. These issues are also likely to further
be interpreted by the FCC as it construes the federal legislation.
 
  In March 1995, MFS introduced an initiative before the FCC calling for the
nationwide unbundling of the "local loops" controlled by the LECs in order to
make those facilities available on a cost-based basis to all eligible local
service providers, including MFS, following initiation of local competition.
The local loop is the part of the LEC networks that physically connects the
customer's premises to the central office and is used to receive and originate
local and long distance calls. The Company is simultaneously pursuing similar
initiates before individual state regulatory commissions and has obtained
orders or entered into agreements with incumbent LECs to obtain unbundled
loops in a number of states. The FCC will address local loop unbundling and
related unbundling issues in connection with its interpretation of the Telecom
Act.
 
  In July 1995, the FCC took two actions related to the assignment of
telephone numbers, first mandating that over the course of the next year
responsibility for administering and assigning local telephone numbers be
transferred from the BOCs and a few other LECs to a neutral entity, and
second, proposing a regulatory structure under which a wide range of number
portability issues would be resolved. The FCC is expected to address these and
other number portability issues in connection with its ongoing interpretation
of the Telecom Act. The Company envisions that the FCC will initiate many
additional proceedings, as a result of the enactment of federal legislation,
defining and construing the terms, conditions and prices of the various
components necessary for local competition.

  State Regulation. Historically, certain of the Company's private line and
special access circuits were classified as intrastate and therefore subjected
to state regulation. As its local service business and product lines expand,
the Company will be offering more intrastate service and will increasingly be
subject to state regulation. In all states where certification is required,
except the District of Columbia, the Company's operating subsidiaries are
certificated as common carriers. In May 1996, the Company asked the FCC to
preempt the District of Columbia PSC in a manner which would authorize the
Company to provide local service in the District, irrespective of any action
or lack of action by the District of Columbia PSC regarding the Company's
pending application to offer local service. In all states, the Company
believes that it operates with the appropriate state regulatory authorization.
The Company currently is authorized to provide intrastate toll or a
combination of local and intrastate toll service in 48 states. These
authorizations vary in the scope of the intrastate services permitted. In most
of the jurisdictions where the Company has network facilities, it is
authorized to provide competitive local exchange services. Following passage
of the Telecom Act, the Company is in the process of seeking to expand and
improve upon the scope of its intrastate certifications to offer competitive
local switched services in all markets where it has network facilities.
Further, the Company is initiating or furthering local interconnection
discussions with LECs in all such markets.
 
  In connection with passage of the Telecom Act, which provides the states
various opportunities to implement the Telecom Act, the Company continues to
support efforts at the state level to establish specific procedures
introducing competition in local markets and to permit MFS to operate on the
same basis and with the same rights as the incumbent LECs. Currently, a number
of state public utility commissions have both allowed local competition and
endowed MFS and other non-dominant carriers with varying degrees of co-carrier
status. These include a number of key states including California,
Connecticut, Florida, Illinois, Maryland, Massachusetts, Michigan, New York,
Ohio, Oregon, Pennsylvania, Texas and Washington. These states, in
combination, represent a significant percentage of MFS' domestic customer
base. MFS is in the process of obtaining or improving upon co-carrier
arrangements in all jurisdictions where it has network facilities. As a result
of co-carrier status, MFS expects to realize lower costs for providing
switched local services, which is jurisdictionally intrastate and currently
subject to state regulation.
 
  Under the Telecom Act, MFS has entered into interconnection discussions with
all LECs in areas where MFS conducts business. In January 1995, MFS entered
into an interim agreement with New York Telephone Company which addressed,
among other things, reciprocal compensation and number portability in the New
York market. The Company believes that the New York agreement was the first of
its kind, and combined with a previous agreement on interconnection, direct
assignment of numbers and local loop unbundling, served as a model for co-
carrier agreements with other LECs. A similar agreement was concluded with New
England Telephone and Telegraph Company. On November 20, 1995, the Company
announced that it entered into a comprehensive agreement with Pacific Bell.
The MFS-Pacific Bell agreement addresses number portability, reciprocal
compensation, unbundled local loops and other significant financial and
technical arrangements of co-carrier status with respect to Pacific Bell's
operating territory in California, the Company's largest state market. This
agreement, with modest modifications, has been approved by the PUC. The
Company believes that this agreement could provide a model for future co-
carrier arrangements with other LECs. On February 19, 1996, the Company
entered into a partial co-carrier agreement with GTE-Florida which is largely
modeled on the MFS-Pacific Bell agreement. On April 9, 1996, the Company
entered into a partial co-carrier agreement with GTE-California. The Company
also has interconnection agreements with other LECs. Under the Telecom Act,
the Company is seeking to expand the scope and improve the terms of its
various interconnection agreements.
 
  Local Government Authorizations. The Company is required to obtain street
opening and construction permits to install and expand its fiber optic
networks. In some of the metropolitan areas where the Company provides network
services, the MFS Telecom Companies pay license or franchise
 
                                      73

fees based on a percent of gross revenues or other formulas. These fees are
often higher than those paid by incumbent LECs. Under the Telecom Act, the
Company may determine to challenge or re-negotiate certain of these
agreements.
 
  International. Historically, the European telecommunications environments
was a closed market consisting almost exclusively of PTTs or other incumbent
monopoly operators. Recently, however, the regulatory framework in Europe has
begun to change. European countries are beginning to privatize their
telecommunications carriers. Other foreign markets are also experiencing
increased competition. The European Union in 1990 issued a directive to its
member states to liberalize telecommunications services other than switched
voice services by opening their monopoly markets. The European Council of
Ministers has established a January 1, 1998 deadline on liberalizing switched
voice services in most European countries. The European Union further proposed
that by July 1996, most member states allow facilities based competition for
liberalized services. Individual countries, like the United Kingdom and
Sweden, have determined to allow local competition and competitive
infrastructure prior to that prescribed deadline. Most countries have
announced their intent to meet the European Union's competitive goal no later
than January 1, 1998. The Company is seeking on a country-by-country basis to
accelerate those dates. There is no assurance that the Company will be
successful in these activities, and if it is, the specific terms and
conditions under which such services will be allowed.
 
  Internet-related services are not currently subject to direct regulation by
the FCC or any other U.S. agency, other than regulation applicable to
businesses generally. The FCC recently requested comments on a petition filed
by the America's Carriers Telecommunication Association which requests that
the FCC regulate certain voice transmissions over the Internet as
telecommunications services. Changes in the regulatory environment relating to
the telecommunications or Internet-related services industry, could have an
adverse effect on the Company's Internet-related services business. The
Telecom Act may permit telecommunications companies, BOCs or others to
increase the scope or reduce the cost of their Internet access services. The
Company cannot predict the effect that the Telecom Act or any future
legislation, regulation or regulatory changes may have on its business.

                           DESCRIPTION OF THE MERGER
 
  The following description of the Merger is necessarily a summary thereof and
is therefore qualified in its entirety by reference to the Merger Agreement,
the Stock Option Agreement and the MFS Voting Agreement.
 
                             THE MERGER AGREEMENT
 
  The Merger Agreement provides that, subject to the approval by the
stockholders of each of UUNET and MFS and the satisfaction or waiver of the
other conditions to the Merger, a wholly owned subsidiary of MFS ("Sub") will
be merged with and into UUNET in accordance with Delaware law, with UUNET as
the surviving corporation of the Merger (the "Surviving Corporation"). On the
Effective Date (as defined in the Merger Agreement), the conversion of UUNET
Common Stock into MFS Common Stock will be effected as described below and
UUNET will become a wholly owned subsidiary of MFS. The directors of Sub
immediately prior to the Effective Date as well as John W. Sidgmore and
Richard L. Adams, Jr. will become the directors of the Surviving Corporation,
and the officers of UUNET immediately prior to the Effective Date will be the
officers of the Surviving Corporation, in each case until their respective
successors are duly elected and qualified.
 
EFFECTIVE DATE
 
  Following the adoption of the Merger Agreement and the transactions
contemplated thereby by the stockholders of each of UUNET and the approval of
the MFS Share Proposal by the Stockholders of MFS and subject to satisfaction
or waiver of certain terms and conditions, including conditions to closing,
contained in the Merger Agreement, the Merger will become effective on such
date as the Certificate of Merger is duly filed with the Secretary of State of
Delaware or at such time thereafter as is provided in such Certificate. The
filing of the Certificate of Merger will be made as soon as practicable after
all conditions contemplated by the Merger Agreement have been satisfied or
waived.
 
TERMS OF THE MERGER
 
  At the Effective Date each outstanding share of UUNET Common Stock (other
than shares of UUNET Common Stock held by UUNET or any subsidiary of UUNET or
held by MFS or any subsidiary of MFS on the Effective Date, which will be
cancelled without payment) will be converted into and represent the right to
receive 1.777776 shares of MFS Common Stock, with cash in lieu of fractional
shares. Each share of MFS Common Stock issued in connection with the Merger
will be accompanied by the right to purchase one one-thousandth of a share of
Series C Junior Participating Preferred Stock, par value $0.01 per share ("MFS
Rights").
 
  As of the Effective Date, present holders of UUNET Common Stock will cease
to have any rights as holders of such shares, but will have the rights of
holders of MFS Common Stock. After the Effective Date, the stock transfer
books of UUNET will be closed and there will be no further transfers of UUNET
Common Stock.
 
STOCK OPTIONS AND STOCK PURCHASE PLAN
 
  At or prior to the Effective Date, UUNET and MFS will take all action
necessary to cause the assumption by MFS as of the Effective Date of the
options to purchase UUNET Common Stock, whether vested or unvested, issued
under UUNET's 1995 Performance Option Plan, Incentive Stock Option Plan,
Equity Incentive Plan and Nonemployee Directors Stock Option Plan (the "Stock
Option Plans") or pursuant to separate option agreements outstanding as of the
Effective Date (collectively, the "Outstanding Options"). Each of the
Outstanding Options will be converted without any action on the part of the
holder thereof into an option to purchase shares of MFS Common Stock as of the
 
                                      80
<PAGE>
 
Effective Date. The number of shares of MFS Common Stock that the holder of an
assumed Outstanding Option will be entitled to receive upon the exercise of
such option will be a number of whole shares determined by multiplying the
number of shares of UUNET Common Stock subject to such option, determined
immediately before the Effective Date, by the Exchange Ratio. The option price
of each share of MFS Common Stock subject to an Outstanding Option will be the
amount (rounded up to the nearest whole cent) obtained by dividing the
exercise price per share of UUNET Common Stock at which such option is
exercisable immediately before the Effective Date by the Exchange Ratio. The
assumption and substitution of options as provided in the Merger Agreement
will not give the holders of such options additional benefits or additional
vesting rights (other than rights to the acceleration of vesting or the lapse
of the right of repurchase caused by the Merger under existing contractual
arrangements) which they did not have immediately prior to the Effective Date
or relieve the holders of any obligations or restrictions applicable to their
options or the shares obtainable upon exercise of the options. After the
Effective Date, the Stock Option Plans will be continued in effect by MFS
subject to amendment, modification, suspension, abandonment or termination as
provided therein, and the Stock Option Plans as so continued will relate only
to the issuance of MFS Common Stock as provided in the Merger Agreement. No
later than one day after the Effective Date of the Merger, MFS shall file a
Registration Statement on Form S-8 relating to the assumed Outstanding
Options.
 
  Upon the earlier to occur of July 31, 1996 or the trading day immediately
preceding the Effective Date, all then outstanding rights to acquire shares of
UUNET Common Stock under UUNET's Employee Stock Purchase Plan (the "Stock
Purchase Plan") will be exercised for the purchase of shares of UUNET Common
Stock. No later than the close of the second trading day immediately preceding
the Effective Date (but not prior to the exercise mentioned in the preceding
sentence), the Board of Directors of UUNET will terminate the Stock Purchase
Plan and all outstanding options to purchase UUNET Common Stock under such
plan. All funds contributed to such Stock Purchase Plan that were not used to
purchase shares of UUNET Common Stock will be returned, in cash, to
participants of the Stock Purchase Plan as soon as administratively feasible
after such termination date, in accordance with the terms of the Stock
Purchase Plan.

COVENANTS
 
  Each of UUNET and MFS and their respective subsidiaries will give the other
access throughout the period prior to the Effective Date to its properties,
books, contracts, commitments, records and personnel. UUNET and MFS have
further agreed to prepare and file with the Commission a registration
statement consisting of a joint proxy statement and a prospectus with respect
to the MFS Common Stock to be issued in connection with the Merger and MFS has
agreed to make all necessary filings with respect to the transactions
contemplated by the Merger under applicable state securities laws.
 
  Prior to the Effective Date, UUNET has agreed to deliver to MFS a list
identifying all persons who were, in UUNET's reasonable judgment, "affiliates"
of UUNET as that term is used in Rule 145 under the Securities Act (the
"Affiliates"). UUNET agreed to use all reasonable efforts to obtain, and
deliver to MFS, agreements from all Affiliates that they will not sell MFS
Common Stock unless such sale has been registered under the Exchange Act, such
sale is effected in compliance with Rule 145, or in the opinion of counsel, or
pursuant to a "no action" letter obtained from the staff of the Commission,
such sale is exempt from registration under the Securities Act.
 
  MFS has agreed to use its best efforts to list the MFS Common Stock issued
pursuant to the Merger on the Nasdaq National Market.
 
  UUNET and MFS have filed notifications under the HSR Act in connection with
the Merger and the transactions contemplated thereby, and have agreed to
respond as promptly as practicable to any inquiries received from the Federal
Trade Commission (the "FTC") and the Antitrust Division of the Department of
Justice (the "Antitrust Division") for additional information and
documentation and to respond as promptly as possible to all inquiries and
requests from any State Attorney General or other governmental authority in
connection with antitrust matters.
 
                                      84
<PAGE>
 
  UUNET and MFS have agreed to use all reasonable efforts to take, or cause to
be taken, all actions and to do, or cause to be done, all things necessary,
proper or advisable under applicable laws and regulations to consummate and
make effective the transactions contemplated by the Merger Agreement,
including using all reasonable efforts to obtain all necessary waivers,
consents and approvals, to effect all necessary registrations and filings
(including, but not limited to, filings under the HSR Act and with all
applicable governmental entities) and to lift any injunction or other legal
bar to the Merger (and, in such case, to proceed with the Merger as
expeditiously as possible), subject, however, in the case of the Merger
Agreement and the MFS Share Proposal, to the appropriate vote of the
stockholders of UUNET and MFS. Notwithstanding the foregoing, there will be no
action required to be taken and no action will be taken in order to consummate
and make effective the transactions contemplated by the Merger Agreement if
such action, either alone or together with another action, would have a
material adverse effect on either UUNET or MFS.
 
  Following the Effective Date, MFS will use its best efforts to conduct its
business, and will cause the Surviving Corporation to use its best efforts to
conduct its business, except as otherwise contemplated by the Merger
Agreement, in a manner which would not jeopardize the characterization of the
Merger as a reorganization within the meaning of Section 368(a) of the Code.
 
  MFS agreed that from the date of the Merger Agreement until the Effective
Date, it would not participate in discussion or negotiations with, or enter
into any agreement pursuant to which MFS would acquire or agree to acquire by
merging or consolidating with, or by purchasing a substantial equity interest
in, or by any other manner, any business or any part thereof where either (i)
the acquired business is in the business of providing Internet access, (ii)
the acquisition would involve aggregate consideration in excess of
$500,000,000, or (iii) the acquisition could reasonably be expected to delay
the satisfaction of the conditions set forth in the Merger Agreement.
 
EFFECT ON EMPLOYEE BENEFIT PLANS
 
  MFS agreed to honor in accordance with their terms, all employment,
severance and similar agreements to which UUNET or any subsidiary is a party
and all accrued benefits that are vested as of the Effective Date under any
UUNET benefit plan or Stock Option Plan, except as provided by the terms of
such agreement. MFS agreed to provide employees of UUNET and its subsidiaries
with credit for all service with UUNET or its affiliates for purposes of
vesting and eligibility under any employee benefit plan, program or
arrangement of MFS or its affiliates, including all employee equity incentive
programs of MFS. MFS agreed that employees of UUNET and its subsidiaries who
continue to be employed by MFS or its subsidiaries after the Effective Date
may continue to participate in their current UUNET sponsored employee benefit
programs for twelve months following the Effective Date. After the Effective
Date, employees of UUNET and its subsidiaries will be eligible to participate
in the appropriate employee equity incentive programs of MFS, as determined by
MFS in its sole discretion.
 
NO SOLICITATION
 
  Neither UUNET nor any of its subsidiaries will, directly or indirectly, take
(nor will UUNET authorize or permit its subsidiaries, officers, directors,
employees, representatives, investment bankers, attorneys, accountants or
other agents or affiliates, to take) any action to (i) encourage, solicit or
initiate the submission of any Acquisition Proposal (as defined below), (ii)
enter into any agreement with respect to any Acquisition Proposal or (iii)
participate in any way in discussions or negotiations with, or furnish any
information to, any person in connection with, or take any other action to
facilitate any inquiries or the making of any proposal that constitutes, or
may reasonably be expected to lead to, any Acquisition Proposal; provided,
however that UUNET or its Board of Directors may (a) furnish non-public
information to, or enter into discussions with any person or entity in
connection with an unsolicited bona fide written Acquisition Proposal by such
person or entity, if prior to furnishing such non-public information to, or
entering into discussions or negotiations with such person or entity, an
executed confidentiality agreement is received from such person or entity, (b)
withdraw UUNET's
 
                                      85
<PAGE>
 
Board of Directors' recommendation of the Merger, if and only to the extent
that UUNET's Board of Directors believes in good faith (after consultation
with and based upon the advice of its financial advisor) that such Acquisition
Proposal would, if consummated, result in a transaction more favorable to
UUNET's stockholders than the Merger and the UUNET Board of Directors
determines in good faith after consultation with and based upon a written
opinion of its outside legal counsel that such withdrawal is necessary for the
directors to comply with their fiduciary duties to the stockholders under
applicable Delaware law and that such withdrawal will not affect the validity
of the submission of the Merger Agreement to the stockholders of UUNET
pursuant to Delaware law or the enforceability of the Stock Option Agreement
or (c) comply with Rule 14e-2(a)(2) or (3) promulgated under the Exchange Act
with regard to an Acquisition Proposal. UUNET will promptly communicate to MFS
any solicitation by UUNET and the terms of any proposal or inquiry, including
the identity of the person and its affiliates making the same, that it may
receive in respect of any such transaction, or of any such information
requested from it or of any such negotiations or discussions being sought to
be initiated with it. "Acquisition Proposal" means any proposed (a) merger,
consolidation or similar transaction involving UUNET, (b) sale, lease or other
disposition directly or indirectly by merger, consolidation, share exchange or
otherwise of assets of UUNET or its subsidiaries representing 10% or more of
the consolidated assets of UUNET and its subsidiaries, (c) issue, sale, or
other disposition of (including by way of merger, consolidation, share
exchange or any similar transaction) securities (or options, rights or
warrants to purchase, or securities convertible into, such securities)
representing 10% or more of the voting power of UUNET or (d) transaction in
which any person will acquire beneficial ownership (as such term is defined in
Rule 13d-3 under the Exchange Act), or the right to acquire beneficial
ownership or any "group" (as such term is defined under the Exchange Act) will
have been formed which beneficially owns or has the right to acquire
beneficial ownership of 25% or more of the outstanding UUNET Common Stock.
 
INDEMNIFICATION
 
  MFS and UUNET, as the Surviving Corporation, will jointly and severally
indemnify and hold harmless directors, officers, and agents of UUNET as
provided in UUNET's Certificate of Incorporation, By-laws or indemnification
agreements, in effect on the date of the Merger Agreement with respect to
matters occurring through the Effective Date. The Merger Agreement provides
that the By-laws and the Certificate of Incorporation of Sub will be amended
prior to the Effective Date to contain indemnification provisions identical to
those set forth in the By-laws and Certificate of Incorporation of UUNET as of
April 29, 1996, which provisions will continue in full force and effect for a
period of not less than six years from the Effective Date. The Merger
Agreement provides that, with respect to matters occurring prior to the
Effective Date, MFS will cause UUNET, as the Surviving Corporation, to
maintain directors' and officers' liability insurance policies as currently
maintained by UUNET for three years after the Effective Date to the extent
that such policies are obtainable at an annual cost of not greater than three
times UUNET's last annual premium prior to April 29, 1996; provided that if
such coverage is not available for such amount, UUNET, as the Surviving
Corporation will purchase as much coverage as possible for such amount.
 
  The Merger Agreement provides that under certain circumstances, MFS will
indemnify and hold harmless each member of UUNET's Board of Directors that has
executed, or whose affiliate or employer executed, a Stock Option Agreement
insofar as any loss, claim, damage, liability or expense arises solely out of,
or is based solely upon, a claim that such Director's fiduciary duty as a
member of UUNET's Board of Directors under Delaware law was breached by the
execution by him or his affiliate or employer, in his or its capacity as a
UUNET stockholder, of the Stock Option Agreement.
 
TERMINATION; FEES AND EXPENSES
 
  The obligations of UUNET and MFS to consummate the Merger are subject to
various conditions as described above under "--Conditions to Consummation of
the Merger."
 
                                      86
<PAGE>
 
  The Merger Agreement may be terminated at any time prior to the Effective
Date, whether before or after approval of the matters presented in connection
with the Merger by the stockholders of UUNET as follows: (i) by mutual consent
of the Boards of Directors of UUNET and MFS; (ii) by either MFS or UUNET if
the Merger has not been consummated on or before November 30, 1996; (iii) by
UUNET if any of the conditions to its obligations to consummate the Merger
have not been met or waived by UUNET at such time as such condition is no
longer capable of satisfaction; (iv) by MFS if any of the conditions to its
obligations to consummate the Merger have not been met or waived by MFS at
such time as such condition is no longer capable of satisfaction; (v) in the
event of a Purchase Event (as defined below) or (vi) by either MFS or UUNET,
if the approval of UUNET's stockholders to the Merger is not obtained at the
UUNET Special Meeting; or (vii) by either MFS or UUNET if the approval of MFS'
stockholders to the MFS Share Proposal is not obtained at the Annual Meeting
of stockholders of MFS and at any and all adjournments or postponements
thereof (the "MFS Annual Meeting").
 
  If the Merger Agreement is terminated by MFS because of a failure by the
UUNET stockholders to approve the Merger, the failure of UUNET to perform in
all material respects its agreements contained in the Merger Agreement on or
prior to the Effective Date or the failure of the representations and
warranties of UUNET contained in the Merger Agreement to be true in all
material respects when made and on and as of the Effective Date as if made on
and as of such date, except to the extent they relate to a particular date,
and within 18 months after the date of such termination, UUNET accepts or
recommends to its stockholders for approval an Acquisition Proposal that MFS
believes would result in a transaction more favorable to UUNET's stockholders
than the Merger and such Acquisition Proposal is consummated, UUNET is
obligated to pay MFS a fee of $60 million. If the Merger Agreement is
terminated by UUNET because of a failure by the MFS stockholders to approve
the MFS Share Proposal, the failure of MFS or Sub to perform in all material
respects their agreements contained in the Merger Agreement on or prior to the
Effective Date or the failure of the representations and warranties of MFS or
Sub contained in the Merger Agreement to be true in all material respects when
made on and as of the Effective Date as if made on and as of such date, except
to the extent they relate to a particular date, MFS is obligated to pay UUNET
a fee of $60 million and, at UUNET's option, purchase 1,551,724 shares of
UUNET Common Stock for $90 million and, at UUNET's option, provide up to $100
million of certain data communications services to UUNET at MFS' cost over
five years, with no more than $25 million in any one year.
 
  Generally, all costs and expenses incurred in connection with the Merger
will be paid by the party incurring such expense.
 
AMENDMENT; WAIVER
 
  The Merger Agreement provides that it may be amended by the parties thereto,
by or pursuant to action taken by the respective Boards of Directors, at any
time before or after approval thereof by the stockholders of UUNET and MFS,
but, after such approval, no amendment may be made which changes the Exchange
Ratio or which in any way materially adversely affects the rights of such
stockholders, without such further approval of such stockholders. The Merger
Agreement may not be amended except by an instrument in writing signed on
behalf of each of MFS, Sub and UUNET.
 
  At any time prior to the Effective Date, the parties to the Merger
Agreement, by or pursuant to action taken by their respective Boards of
Directors, may: (i) extend the time for the performance of any of the
obligations or other acts of the other parties thereto; (ii) waive any
inaccuracies in the representations and warranties contained therein or in any
documents delivered pursuant thereto; and (iii) waive any compliance with any
of the agreements or conditions contained therein. Any agreement on the part
of a party to the Merger Agreement to any such extension or waiver will be
valid if set forth in an instrument in writing signed on behalf of such party.

                          THE STOCK OPTION AGREEMENT
 
NUMBER OF SHARES; EXERCISE PRICE
 
  Pursuant to the terms of the Stock Option Agreement, certain stockholders of
UUNET have granted to MFS an irrevocable option (the "Option") to acquire all
of such stockholders' shares of UUNET Common Stock (the "Option Shares")
representing approximately 60% of the issued and outstanding shares of the
UUNET Common Stock for the Exchange Ratio and cash in lieu of fractional
shares. Each share of new MFS Common Stock issued in connection with the
Option exercise will be accompanied by one MFS Right. The Option may only be
exercised following the occurrence of a Purchase Event (as defined below), and
may be exercised only once. The shares of UUNET Common Stock subject to the
Stock Option Agreement are held by the following stockholders (each a "UUNET
Stockholder and collectively the "UUNET Stockholders"): Richard L. Adams, Jr.;
John W. Sidgmore; Les B. Strauss; Daniel C. Lynch; Microsoft; Menlo Ventures
IV, L.P.; Menlo Evergreen V, L.P.; New Enterprise Associates V, Limited
Partnership, Accel IV L.P. and Accel Investors '93 L.P.
 
EXERCISE OF THE OPTION
 
  The Option is exercisable, in whole but not in part, only upon the
occurrence of one of the following events (each a "Purchase Event"):
 
    (i) any person (other than MFS or any subsidiary of MFS, having commenced
  (as such term is defined in Rule 14d-2 under the Exchange Act), a tender
  offer or exchange offer to purchase any shares of UUNET Common Stock such
  that, upon consummation of such offer, such person would own or control 50%
  or more of the then outstanding UUNET Common Stock, and the Board of
  Directors of UUNET, within ten business days after such tender or exchange
  offer shall have been so commenced, fails to recommend against acceptance
  of such tender or exchange offer by its stockholders, and MFS delivers a
  written notice of termination to UUNET within (20) business days after the
  expiration of such 10 day period;
 
    (ii) UUNET or any subsidiary of UUNET having authorized, recommended,
  proposed or publicly announced an intention to authorize, recommend or
  propose, or entered into, an agreement with any person (other than MFS or
  any subsidiary of MFS) to (i) effect a merger, consolidation or similar
  transaction involving UUNET or any of its material subsidiaries, (ii) sell,
  lease or otherwise dispose of assets of UUNET or its subsidiaries
  representing 10% or more of the consolidated assets of UUNET and its
  subsidiaries (other than in the ordinary course of business) or (iii)
  issue, sell or otherwise dispose of (including by way of merger,
  consolidation, share exchange or any similar consolidation, share exchange
  or any similar transaction) securities (or options, rights or warrants to
  purchase, or securities convertible into, such securities) representing 10%
  or more of the voting power of UUNET or any of its subsidiaries; or
 
    (iii) any person (other than MFS, any subsidiary of MFS, UUNET or any of
  its subsidiaries in a fiduciary capacity) has acquired beneficial ownership
  (as such term is defined in Rule 13d-3 under the Exchange Act) or the right
  to acquire beneficial ownership of, or any "group" (as such term is defined
  under the Exchange Act) shall have been formed which beneficially owns or
  has the right to acquire beneficial ownership of, 25% or more of the then
  outstanding UUNET Common Stock.
 
  The Option shall terminate and be of no further force and effect upon the
earliest to occur of (i) the Effective Date, (ii) 20 business days after the
termination of the Merger Agreement other than by reason of an event described
in clause (iii) or (iv) below, (iii) exercise of UUNET's right to terminate
the Merger Agreement because of a breach by MFS or Sub of any covenant or
agreement set forth in the Merger Agreement or the failure of any
representation or warranty of MFS or Sub under the Merger
 
                                      88
<PAGE>
 
Agreement or of MFS under the Stock Option Agreement to have been true in all
material respects when made or the failure of the stockholders of MFS to
approve the Merger at the MFS Annual Meeting, (iv) termination of the Merger
Agreement pursuant to mutual consent of MFS and UUNET or the failure to
consummate the Merger by November 30, 1996, or (v) the failure of the closing
of the purchase and sale pursuant to the Option to occur within 30 business
days of the date each stockholder is sent written notice of the exercise of
the Option unless (A) the reason for such failure relates to the inability to
satisfy the conditions to register the shares of MFS Common Stock pursuant to
the Securities Act or for the notification period under the HSR Act to have
expired, in either case, for reasons outside the control of MFS, and (B) MFS
is diligently pursuing the registration of such shares with the Commission or
promptly providing all necessary information to the FTC and the Antitrust
Division as the case may be. Notwithstanding the termination of the Option,
MFS will be entitled to purchase the Option Shares in accordance with the
terms hereof if it has exercised the Option prior to the termination date,
unless clause (iii) or (v) above has been triggered in which case the rights
to exercise this Option will immediately cease.
 
  The consummation of a purchase or a repurchase pursuant to the Stock Option
Agreement is subject to, among other things, the registration of the Option
Shares of MFS Common Stock to be issued upon Option exercise and obtaining any
required regulatory approvals. In the event that prior notification to or
approval of any regulatory authority is required in connection with such
purchase, MFS and, if applicable, a UUNET stockholder will promptly file the
required notice or application for approval and will expeditiously process the
same (and such stockholder will cooperate with MFS in the filing of any such
notice or application and the obtaining of any such approval), and the period
of time that otherwise would run shall run instead from the date on which, as
the case may be, (i) any required notification period has expired or been
terminated or (ii) such approval has been obtained, and in either event, any
requisite waiting period has passed. MFS included the issuance of shares of
MFS Common Stock under the Stock Option Agreement in the notifications under
the HSR Act filed with respect to the Merger.
 
 ADJUSTMENT OF NUMBER OF SHARES SUBJECT TO OPTION
 
  If on or after the date of the Stock Option Agreement there occurs any stock
dividend, stock split, recapitalization, combination or exchange of shares,
merger, consolidation, reorganization or other change or transaction of or by
UUNET, as a result of which shares of any class of stock, other securities,
cash or other property will be issued in respect of any Option Shares or if
any Option Shares shall be changed in the same or another class of stock or
other securities, then, upon exercise of the Option, MFS will receive for the
aggregate price payable upon exercise of the Option, all such shares of stock,
other securities, cash or other property issued, delivered or received with
respect to such Option Shares.
 
 AGREEMENT TO VOTE
 
  Each UUNET Stockholder agreed that from April 29, 1996, to the earlier to
occur of the termination of the Merger Agreement or the Effective Date, at any
meeting of the stockholders of UUNET, however called, and in any action by
consent of the stockholders of UUNET, such UUNET Stockholders will vote the
Option Shares, representing approximately 60% of the outstanding UUNET Common
Stock (a) in favor of the Merger, the Merger Agreement (as amended from time
to time) and the transactions contemplated by the Merger Agreement and (b)
against any proposal for any recapitalization, merger (other than the Merger),
sale of assets or other business combination between UUNET and any person or
entity (other than MFS or Sub) or any other action or agreement that would
result in a breach of any covenant, representation or warranty or any other
obligation or agreement of UUNET under the Merger Agreement or which would
result in any of the conditions to the Merger Agreement not being fulfilled.
 
                                      89
<PAGE>
 
GRANT OF PROXY
 
  Each UUNET Stockholder granted an irrevocable proxy in favor of MFS and Sub
to vote all of such UUNET stockholder's Option Shares: (i) in favor of the
Merger, the Merger Agreement (as amended from time to time) and the
transactions contemplated by the Merger Agreement; and (ii) against any
proposal for any recapitalization, merger (other than the Merger), sale of
assets or other business combination between UUNET and any person or entity
(other than MFS or Sub) or any other action or agreement that would result in
a breach of any covenant, representation or warranty or any other obligation
or agreement of UUNET under the Merger Agreement or which would result in any
of the conditions to the Merger Agreement not being fulfilled. The irrevocable
proxy granted by each UUNET Stockholder terminates upon the earlier to occur
of the Effective Date or the termination of the Merger Agreement.
 
 RESTRICTIONS ON TRANSFER
 
  Each UUNET Stockholder agreed that, from April 29, 1996 to the termination
of the rights of MFS under the Stock Option Agreement, it will not offer or
agree to sell, transfer, tender, assign, hypothecate or otherwise dispose of,
or create or permit to exist any encumbrance on the shares owned by such UUNET
Stockholder at any time prior to the Effective Date; provided that Mr. Adams
may sell, gift or otherwise transfer 325,000 shares of UUNET Common Stock.
 
                             MFS VOTING AGREEMENT
 
 VOTING AGREEMENT
 
  Pursuant to the Parent Voting and Proxy Agreement, dated as of April 29,
1996 (the "MFS Voting Agreement"), certain stockholders of MFS have agreed
that during the time the MFS Voting Agreement is in effect, at any meeting of
the MFS stockholders, however called, and in any action by written consent of
the MFS stockholders, such stockholders will vote in favor of the MFS Share
Proposal and have granted irrevocable proxies in favor of UUNET to vote all of
such stockholders' shares of MFS Common Stock held in favor of the MFS Share
Proposal.
 
  The shares of MFS Common Stock subject to the terms the MFS Voting Agreement
and the irrevocable proxies, representing approximately 12% of the outstanding
shares of MFS Common Stock prior to the Offerings, are held by the following
MFS stockholders: James Q. Crowe, Howard Gimbel, William L. Grewcock, Royce J.
Holland, Richard R. Jaros, Robert E. Julian, Ronald W. Roskens, Walter Scott,
Jr., Kenneth E. Stinson and Michael B. Yanney.
 
 NO DISPOSITION OR ENCUMBRANCE OF SHARES AND OPTIONS
 
  Each stockholder agreed that, from April 29, 1996 until the termination of
the MFS Voting Agreement, he will not, and will not offer or agree to, sell,
transfer, tender, assign, hypothecate or otherwise dispose of, or create or
permit to exist any encumbrance on the shares of MFS Common Stock subject to
the terms of the MFS Voting Agreement at any time prior to the Effective Date.
 
 TERMINATION
 
  The MFS Voting Agreement terminates upon the earlier of the Effective Date
or November 30, 1996.

                        DESCRIPTION OF MFS CAPITAL STOCK
 
  The summary of the terms of the stock of MFS set forth below does not purport
to be complete and is subject to and qualified in its entirety by reference to
the Amended and Restated Certificate of Incorporation and By-laws of MFS.
 
GENERAL
 
  The aggregate number of shares of capital stock of all classes which MFS has
authority to issue is 425,000,000, of which 400,000,000 shares are MFS Common
Stock, $.01 par value, and 25,000,000 shares are preferred stock, $.01 par
value (the "MFS Preferred Stock"). The issued and outstanding shares of MFS
Common Stock and MFS Preferred Stock, are duly authorized, validly issued,
fully paid and nonassessable.
 
  The additional shares of authorized stock available for issuance by MFS might
be issued at such times and under such circumstances as to have a dilutive
effect on earnings per share and on the equity ownership of the holders of MFS
Common Stock. The ability of the MFS Board of Directors to issue additional
shares of stock could enhance the MFS Board of Directors' ability to negotiate
on behalf of the stockholders in a takeover situation and also could be used by
the MFS Board of Directors to make a change in control more difficult, thereby
denying stockholders the potential to sell their shares at a premium and
entrenching current management.
 
COMMON STOCK
 
  Subject to the senior rights of Preferred Stock which may from time to time
be outstanding, holders of MFS Common Stock are entitled to receive such
dividends as may be declared by the Board of Directors out of funds legally
available therefor. Upon dissolution and liquidation, holders of MFS Common
Stock are entitled to a ratable share of the net assets of MFS remaining after
payment to the holders of the MFS Preferred Stock of the full preferential
amounts to which they are entitled. All outstanding shares of MFS Common Stock
are fully paid and nonassessable.
 
  The holders of MFS Common Stock are entitled to one vote per share for the
election of Directors and on all other matters submitted to a vote of
stockholders. Holders of Common Stock are not entitled to cumulative voting for
the election of Directors. They are not entitled to preemptive rights.
 
  The transfer agent and registrar for the MFS Common Stock is Continental
Stock Transfer & Trust Company.
 
  As of the date of this Prospectus, there are 125,804,234 shares of MFS Common
Stock outstanding after giving effect to a 2-for-1 stock split effected in the
form of a stock dividend which was payable on April 26, 1996. The MFS Common
Stock is traded on the Nasdaq National Market under the symbol "MFST."
 
PREFERRED STOCK
 
  The MFS Preferred Stock has priority over the MFS Common Stock with respect
to dividends and to other distributions, including the distribution of assets
upon liquidation. The MFS Board of Directors is authorized to fix and determine
the terms, limitations and relative rights and preferences of the MFS Preferred
Stock, to establish series of MFS Preferred Stock and to fix and determine the
variations as among series. The MFS Board of Directors without stockholder
approval could issue MFS Preferred Stock with voting and conversion rights
which could adversely affect the voting power of the holders of MFS Common
Stock.
 
  MFS currently has outstanding a series of MFS Preferred Stock consisting of
95,000 shares of Series A Preferred Stock, and a second series consisting of
15,000,000 shares of Series B Preferred Stock.
 
                                       91
<PAGE>
 
   
  The Series A Preferred Stock was issued on May 23, 1995 in connection with
the sale of 9,500,000 Depositary Shares, each representing a one one-hundredth
interest in a share of Series A Preferred Stock. The liquidation preference of
each share of Series A Preferred Stock is an amount equal to the greater of
(i) the sum of (a) $3,350 and (b) all accrued and unpaid dividends thereon to
the date of liquidation, dissolution or winding up and (ii) the value of the
fraction of a share of MFS Common Stock into which the Series A Preferred
Stock is convertible on the date of such liquidation, dissolution or winding
up. Dividends on the Series A Preferred Stock and the Depositary Shares
representing such Series A Preferred Stock are cumulative from the date of
original issue and are payable quarterly in arrears at the rate of $268.00 per
annum per share of Series A Preferred Stock (equivalent to $2.68 per annum per
Depositary Share). Such dividends are payable in cash or in shares of MFS
Common Stock, at the election of the Company. The Company has paid such
dividends in shares of MFS Common Stock since the issuance of the Series A
Preferred Stock. The Depositary Shares representing such Series A Preferred
Stock may be redeemed for cash at the option of MFS, in whole or in part, at a
call price of the sum of (i) $34.170 on and after the Initial Redemption Date
through August 30, 1998, $34.003 on and after August 31, 1998 through November
29, 1998, $33.835 on and after November 30, 1998 through February 27, 1999,
$33.668 on and after February 28, 1999 through April 29, 1999, and $33.50 on
and after April 30, 1999, until May 31, 1999, plus (ii) all accrued and unpaid
dividends thereon to the date fixed for redemption. On May 31, 1999 (the
"Mandatory Conversion Date"), the Series A Preferred Stock and the Depositary
Shares representing such Series A Preferred Stock are mandatorily convertible
into an aggregate of 19,000,000 shares of MFS Common Stock. The shares of
Series A Preferred Stock are convertible, in whole or in part, at the option
of the holder thereof, at any time prior to the Mandatory Conversion Date,
unless previously redeemed, into shares of MFS Common Stock at a rate of
163.94 shares of Common Stock for each share of Series A Preferred Stock
(equivalent to a conversion price of $20.43 per share of Common Stock), in
either case subject to certain adjustments. The right to convert shares of
Series A Preferred Stock called for redemption will terminate at the close of
business on the redemption date.     
 
  Each share of Series A Preferred Stock is entitled to 10 votes per share
with respect to the election of directors of MFS and each other matter coming
before any meeting of MFS stockholders. The holders of the Series A Preferred
Stock and the holders of MFS Common Stock will vote together as a single
class, unless otherwise provided by law or the Restated Certificate of MFS.
The approval of more than two-thirds of the votes entitled to be cast by the
holders of issued and outstanding shares of Series A Preferred Stock is
required to amend the Amended and Restated Certificate of MFS or to
materially, adversely changes the rights, preferences or privileges of the
Series A Preferred Stock. The holders of the outstanding shares of Series A
Preferred Stock shall also have the right, voting together with the holders of
any other outstanding shares of Voting Preferred Stock (as hereinafter
defined) as a separate voting group, to elect two members of the Board of
Directors of MFS at any time six or more quarterly dividends on any shares of
Voting Preferred Stock shall be in arrears and unpaid, in whole or in part,
whether or not declared and whether or not any funds shall be or have been
legally available for payment thereof. For this purpose, "Voting Preferred
Stock" shall mean the shares of Series A Preferred Stock and each other series
of Preferred Stock which shall have substantially similar voting rights
(including voting as one voting group with other shares of Voting Preferred
Stock) with respect to the election of directors upon substantially similar
arrearages of dividends. In such event, the number of Directors of MFS shall
be increased by two, and, unless a regular meeting of the stockholders of MFS
is to be held within 60 days thereof for the purpose of electing Directors,
within 30 days thereafter, MFS shall call a special meeting of the holders of
the outstanding shares of Voting Preferred Stock for the purpose of electing
such Directors. If such special meeting shall not have been so called by MFS,
or such regular meeting shall not be so held, a special meeting may be called
for such purpose at the expense of MFS by the holders of not less than 10% of
the outstanding shares of any series of Voting Preferred Stock; and notice of
any such special meeting shall be given by the person or persons calling the
same to the holders of the outstanding shares of the Voting Preferred Stock.
At any such special meeting the holders of the outstanding shares of Voting
Preferred Stock
 
                                      92
<PAGE>
 
(voting separately as a class with each share having one vote) shall elect two
members of the Board of Directors of MFS. If a regular meeting of the
stockholders of MFS for the purpose of electing Directors is to be held within
60 days after the time the holders of the outstanding shares of Voting
Preferred Stock become so entitled to elect two Directors, then at such
regular meeting, the holders of the outstanding shares of Voting Preferred
Stock (voting separately as a class with each share having one vote) shall
elect two members of the Board of Directors. The right of the holders of the
Voting Preferred stock (voting separately as a class) to elect two members of
the Board of Directors of MFS shall continue until such time as no dividends
on any outstanding shares of Voting Preferred Stock are in arrears and unpaid,
in whole or in part, at which time (i) the voting power of the holders of the
outstanding shares of Voting Preferred Stock so to elect two Directors shall
cease, but always subject to the vesting of such voting power upon the
occurrence of each and every like arrearage of dividends, and (ii) the term of
office of each member of the Board of Directors who was elected pursuant to
this provision shall automatically expire.
 
  The Series B Preferred Stock is convertible into shares of MFS Common Stock
at any time after the first anniversary of the date of issuance (September 30,
1996) at a conversion price of $21.563. Each share of Series B Preferred Stock
is convertible into .0463768 shares of MFS Common Stock, or an aggregate of
695,652 shares of MFS Common Stock. Dividends on the Series B Preferred Stock
accrue at the rate of 7% per annum and are payable in cash. Dividends will be
paid only when, as and if declared by the Board. The liquidation preference on
each share of Series B Preferred Stock is $1.00, plus all accrued and unpaid
dividends thereon to the date of liquidation, dissolution or winding up. The
Series B Preferred Stock cannot be redeemed by MFS prior to September 30,
2001. Each share of Series B Preferred Stock is entitled to 10 votes per share
with respect to any and all matters presented to the MFS stockholders for
their action and consideration. Holders of Series B Preferred Stock vote
together with the holders of MFS Common Stock as a single class unless
otherwise required by law or the proposed action amends, alters or repeals the
preferences, special rights or other powers of the Series B Preferred Stock.
The shares of Series B Preferred Stock, however, are held subject to an
irrevocable proxy that has been granted to the Secretary and Assistant
Secretary of MFS to vote all shares of Series B Preferred Stock on all
matters, other than the election of directors and matters as to which the
holders of Series B Preferred Stock vote as a separate class, in proportion to
the holders of MFS Common Stock.
 
  The Series B Preferred Stock is non-transferable for a period of six years
from its issuance date, with limited exceptions, and is redeemable at the
option of MFS at the end of such six-year period. Accordingly, the Series B
Preferred Stock has no realizable resale value until the earlier of its
conversion into MFS Common Stock at the option of the holder or the expiration
of the six-year transfer restriction.
 
  MFS has also authorized 75,000 shares to be issued as Series C Preferred
Stock. A description of the terms of the Series C Preferred Stock is set forth
below under "--Preferred Stock Purchase Rights."
 
PREFERRED STOCK PURCHASE RIGHTS
 
  In September 1995, MFS adopted the MFS Rights Plan and in connection
therewith entered into the MFS Rights Agreement. To implement the MFS Rights
Plan, the MFS Board of Directors authorized the issuance of one MFS Right for
each share of MFS Common Stock outstanding as of October 2, 1995 and issued
thereafter until the Distribution Date (as defined in the MFS Rights
Agreement). Each MFS Right entitles the holder to purchase from MFS one one-
thousandth of a share of Series C Preferred Stock at an initial purchase price
of $300, subject to adjustment. The MFS Rights expire on September 30, 2005,
unless extended or earlier redeemed by MFS.
 
                                      93
<PAGE>
 
  The MFS Rights separate from the MFS Common Stock and a Distribution Date
occurs upon the earlier of 10 days following public disclosure that certain
persons or groups of persons have become a beneficial owner of 15% or more of
the outstanding MFS Common Stock (an "Acquiring Person") or 10 business days
following the commencement of a tender offer or exchange offer that would
result in certain persons or groups becoming an Acquiring Person. Upon the
occurrence of a Distribution Date, each holder of a MFS Right has the right to
receive, upon exercise of the right, MFS Common Stock having a value equal to
two times the exercise price of the MFS Right, except that all MFS Rights held
by an Acquiring Person become null and void.
 
  In the event that a person becomes an Acquiring Person and MFS is acquired
in a merger or other business combination in which MFS is not the surviving
corporation or more than 50% of the assets or earning power of MFS' assets are
sold or transferred, each holder, except for Acquiring Persons, of a MFS Right
has the right to receive, upon exercise, common stock of the acquiring company
which has a value equal to two times the exercise price of the MFS Right.
 
  The Series C Preferred Stock will be nonredeemable, and subordinate to all
other series of MFS Preferred. The liquidation preference of each share of
Series C Preferred Stock is an amount equal to (a) 1,000 times the aggregate
amount to be distributed per share to holders of MFS Common Stock and (b)
after the payments set forth in (a), a ratable and proportionate share with
the holders of MFS Common Stock of the remaining assets to be distributed.
Each share of Series C Preferred Stock will be entitled to receive, when, as
and if declared, a quarterly dividend at the rate equal to 1,000 times the
aggregate per share amount of all cash dividends and 1,000 the aggregate per
share amount of all non-cash dividends or other distributions (payable in
kind) (other than a dividends payable in of MFS equity securities). Each share
of Series C Preferred Stock will have 1,000 votes, subject to adjustment,
voting together with the MFS Common Stock and not as a separate class. If MFS
enters into any consolidation, merger, combination or other transaction in
which the shares of MFS Common Stock are exchanged, each share of Series C
Preferred Stock will be entitled to receive 1,000 times the amount received
per share of MFS Common Stock. The rights of the Series C Preferred Stock as
to dividends, voting rights and liquidation are protected by antidilution
provisions.
 
  MFS may redeem the MFS rights in whole, but not in part, at any time until
ten days following the date on which there has been public disclosure that, or
facts indicating that, a person has become an Acquiring Person at a price (the
"Redemption Right") of $.01 per MFS Right (or such other consideration deemed
appropriate by the MFS Board of Directors) by resolution of the MFS Board of
Directors, subject to certain exceptions. The redemption of the MFS Rights may
be made effective at such time on such basis with such conditions as the MFS
Board of Directors in its sole discretion may establish. The MFS Rights
terminate immediately upon the action of the MFS Board of Directors ordering
redemption of the MFS Rights and thereafter the holders of MFS Rights will
only be able to receive the Redemption Price.
 
  Other than provisions relating to the principal economic terms of the MFS
Rights, the MFS Rights Agreement may be amended by resolution of MFS' Board of
Directors, subject to certain exceptions, prior to the Distribution Date.
After the Distribution Date, the MFS Rights Agreement may be amended by
resolution of the MFS' Board of Directors, subject to certain exceptions, in
order to cure any ambiguity, to make changes which do not adversely affect the
interests of holders of MFS Rights (excluding the interests of any Acquiring
Person or its affiliates or associates), or to shorten or lengthen any time
period under the MFS Rights Agreement; provided, however, that no amendment to
adjust the time period governing redemption may be made at such time as the
MFS Rights are no redeemable.
 
  The MFS Rights have certain anti-takeover effects. The MFS Rights will cause
substantial dilution to a person or group that attempts to acquire, or merge
with, MFS without conditioning the offer on the MFS Rights being rendered
inapplicable.

U.S. Underwriters initially propose to offer such Shares 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. The U.S. Underwriters may allow, and such dealers may re-allow, a

additional shares of 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
options, 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, Goldman Sachs International, Bear, Stearns
International Limited, Smith Barney Inc. and UBS Limited are acting as the
representatives (the "International Representatives"), providing for the
concurrent offer and sale of 5,600,000 Shares (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 are

pursuant to their respective agreements must be so purchased. The price to
public and underwriting discount per share 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.

  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 LANs, to deliver traffic at varying rates, permitting a mix
of data, voice and video.
 
  Backbone--A centralized high-speed network that interconnects smaller,
independent networks.
 
  Bandwidth--The number of bits of information which can move through a
communications medium in a given amount of time.
 
  CAP (competitive access provider)--A company that provides its customers
with an alternative to the LEC for local transport of private line and special
access telecommunications services.
 
  Central offices--The switching centers or central switching facilities of
the LECs.
 
  Co-carrier status--A regulatory scheme under which the incumbent LEC is
required to integrate new, competing providers of local exchange service, such
as the Company, into the systems of traffic exchange, inter-carrier
compensation, and other inter-carrier relationships that already exist among
LECs in most jurisdictions.
 
  Collocation--The ability of a CAP such as the Company to connect its network
to the LECs central offices. Physical collocation occurs when a CAP places its
network connection equipment inside the LEC's central offices. Virtual
collocation is an alternative to physical collocation pursuant to which the
LEC permits a CAP to connect its network to the LEC's central offices on
comparable terms, even though the CAP's network connection equipment is not
physically located inside the central offices.
 
  DS-1--A data communications circuit capable of transmitting data at 1.5 Mbps
(sometimes called T-1).
 
  DS-3--A data communications circuit capable of transmitting data at 45 Mbps
(sometimes called T-3).
 
  Dedicated--Telecommunications lines dedicated or reserved for use by
particular customers.
 
  Digital--A method of storing, processing and transmitting information
through the use of distinct electronic or optical pulses that represent the
binary digits 0 and 1. Digital transmission and switching technologies employ
a sequence of these pulses to represent information as opposed to the
continuously variable analog signal. The precise digital numbers minimize
distortion (such as graininess or snow in the case of video transmission, or
static or other background distortion in the case of audio transmission).
 
  E-3--A data communications circuit capable of transmitting data at 34 Mbps
(typically used outside North America).
 
  Ethernet--A local area network technology used for connecting computers,
printers, workstations, terminals, etc., within the same building. Ethernet
operates over twisted wire or coaxial cable at speeds up to 10 megabits per
second. Ethernet is the most popular LAN technology.
 
  FCC--Federal Communications Commission.
 
  FDDI (Fiber Distributed Data Interface)--Based on fiber optics, FDDI is a
100 megabit per second local area network technology used to connect
computers, printers, and workstations at very high speeds. FDDI is also used
as backbone technology to interconnect other LANs.

To the Stockholders and Board of Directors
MFS Communications Company, Inc.
 
  We have audited the accompanying consolidated balance sheets of MFS
Communications Company, Inc. and Subsidiaries as of December 31, 1995 and
1994, and the related consolidated statements of operations, changes in
stockholders' equity, and cash flows for each of the three years in the period
ended December 31, 1995. 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 audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the 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
includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.
 
  In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of MFS
Communications Company, Inc. and Subsidiaries as of December 31, 1995 and
1994, and the consolidated results of their operations and their cash flows
for each of the three years in the period ended December 31, 1995 in
conformity with generally accepted accounting principles.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                 (DOLLARS IN THOUSANDS, EXCEPT PER SHARE DATA)
 
1. ORGANIZATION:
 
  The consolidated financial statements include the accounts of MFS
Communications Company, Inc. ("MFS"), and its majority owned subsidiaries (the
"Company"). MFS was incorporated on July 17, 1987 in Delaware and, prior to
its initial public offering in May 1993, was a wholly owned subsidiary of
Kiewit Diversified Group Inc. ("KDG"), which is a wholly owned subsidiary of
Peter Kiewit Sons', Inc. ("PKS"). In 1995, pursuant to a planned
restructuring, all of PKS' remaining interest in the Company's capital stock
was distributed to certain PKS stockholders.
 
  The Company operates through its subsidiaries in two business segments,
telecommunications services and network systems integration. The
telecommunications segment is comprised of the MFS Telecom Companies, which
provides services to large business and government customers through MFS
Telecom and MFS Datanet, the MFS Intelenet Companies, which provides services
to small and medium sized business customers through MFS Intelenet, MFS
International, which provides services to business and government customers
internationally and Global Network Services, which manages the Company's
international network platform. The network systems integration segment
provides services primarily through MFS Network Technologies.
 
  Where appropriate, items within the consolidated financial statements and
notes thereto have been reclassified from previous years to conform to current
year presentation.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
 (a) Principles of Consolidation:
 
  The consolidated financial statements of the Company include the accounts of
all of its majority owned subsidiaries. All significant intercompany accounts
and transactions have been eliminated.
 
 (b) Recognition of Revenue:
 
  The Company recognizes revenue on telecommunications services in the month
the related service is provided. Network systems integration revenue is
recognized on the percentage-of-completion method of accounting. Under the
percentage-of-completion method, an estimated percentage for each contract, as
determined by the Company's engineering estimate based on the amount of work
performed, is applied to total estimated profit. Provisions for losses are
recognized on uncompleted contracts when they become known. Claims for
additional revenue are recognized in the period when settled. Revisions in
cost and profit estimates, which are always reasonably possible to occur in
the near term under the percentage-of-completion method, are reflected in the
accounting period in which the facts which require the revision become known.
 
 (c) Classification of Current Assets and Liabilities:
 
  In accordance with industry practice, amounts realizable and payable under
network systems integration contracts which may extend beyond one year are
includable in current assets and liabilities. A one-year time period is used
as the basis for classification of all other current assets and liabilities.
 
 (d) Networks and Equipment
 
  The networks and equipment are stated at cost. Various costs are capitalized
during the installation and expansion of the networks. Provisions for
depreciation are computed using straight-line methods over estimated useful
lives beginning in the year an asset is put into service.
 
  Electronic and related equipment, leasehold improvements, furniture and
office equipment and land and buildings are stated at cost. Leasehold
improvements primarily consist of extensions off the network to customer
locations. Depreciation is computed using primarily straight-line methods over
the estimated useful lives of the assets or, for capital leases, the term of
the related leases.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
                 (DOLLARS IN THOUSANDS, EXCEPT PER SHARE DATA)
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED):
 
  Costs of purchased software and certain costs to modify and improve certain
of the Company's computer software are recorded at cost and are being
amortized using the straight-line method over their estimated useful lives.
 
 (e) Intangible Assets:
 
  Costs incurred in developing new networks or expanding existing networks,
including network design, negotiation of rights-of-way and obtaining
legal/regulatory authorizations are deferred and amortized over five years.
 
  Costs incurred to obtain access to buildings are deferred by the Company and
amortized over 15 years. Costs incurred to obtain city franchises are deferred
by the Company and amortized over the initial term of the franchise.
 
  Pre-operating costs represent substantially all nondevelopment costs
incurred during the pre-operating phase of a newly-constructed network and are
amortized over five-year periods commencing with the start of operations.
 
  Goodwill is being amortized primarily over periods of 40 years from the
dates of acquisition. The Company reviews the carrying amount of goodwill for
impairment whenever events or changes in circumstances indicate that the
carrying amount may not be recoverable. Measurement of any impairment would
include a comparison of estimated future operating cash flows anticipated to
be generated during the remaining life of the goodwill to the net carrying
value of the goodwill.
 
  The costs of rights-of-way and customer lists obtained in business
acquisitions are being amortized over estimated useful lives of 20 to 25 years
and three years, respectively.
 
 (f) Income Taxes:
 
  Prior to the Company's initial public offering in May 1993, the Company was
included in the consolidated income tax returns of PKS. Income taxes were
recognized as if the Company filed its own income tax returns on a separate
return basis.
 
  The Company recognizes deferred tax liabilities and assets 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.
 
 (g) Minority Interest:
 
  The Company has recorded the entire loss of other than wholly owned
subsidiaries where the loss applicable to the minority interest exceeds the
minority interest in such subsidiaries' equity.
 
 (h) Translation of Foreign Financial Statements:
 
  Assets and liabilities are translated into U.S. dollars at year-end exchange
rates. Revenues and expenses are translated using the average rates of
exchange for the period. Gains or losses resulting from foreign currency
translation are recorded as adjustments to stockholders' equity.

                 (DOLLARS IN THOUSANDS, EXCEPT PER SHARE DATA)
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED):
 
  Cash equivalents generally consist of highly liquid debt instruments
purchased with a maturity of three months or less.
 
 (j) Marketable Securities:
 
  Marketable securities are being carried at fair value.
 
 (k) Financial Instruments:
 
  Financial instruments which potentially subject the Company to concentration
of credit risk consist principally of marketable securities and accounts
receivable. Concentrations of credit risk of marketable securities is limited
due to investments in short-term, investment grade securities. Concentrations
of credit risk with respect to accounts receivable are limited due to the
dispersion of the Company's customer base among different industries and
geographic areas and remedies provided by terms of contracts and statutes.
 
 (l) Loss Per Share:
 
  Pursuant to Securities and Exchange Commission Staff Accounting Bulletin No.
83, stock options granted with exercise prices below the assumed initial
public offering price of $10.00 per share during the twelve-month period
preceding the date of the initial filing of the Registration Statement have
been included in the calculation of common stock equivalent shares, using the
treasury stock method, as if they were outstanding for the first quarter ended
March 31, 1993. The number of shares used in computing loss per share was as
follows:

</TABLE>
 
 (m) Estimates in Financial Statements:
 
  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.
 
3. FINANCIAL INSTRUMENTS:
 
  The following methods and assumptions were used to determine the
classification and fair value of each class of financial instruments for which
it is practicable to estimate that value:
 
 (a) Cash and cash equivalents:
 
  Cash equivalents generally consist of highly liquid debt instruments
purchased with a maturity of three months or less and are carried at fair
value which approximates cost due to the short maturities.

6. NOTES PAYABLE AND LONG-TERM DEBT (CONTINUED):
 
  In addition, under certain conditions related to a change in control of the
Company, the Company may be required to repurchase all or any part of the 1994
Senior Discount Notes as stipulated in the note agreement. The 1994 Senior
Discount Notes are senior unsecured obligations of the Company and are
subordinated to all current and future indebtedness of the Company's
subsidiaries, including trade accounts payable. The 1994 Senior Discount Notes
contain certain covenants which, among other things, restrict the Company's
ability to incur additional debt, create liens, enter into sale and leaseback
transactions, pay dividends, make certain restricted payments, enter into
transactions with affiliates, and sell assets or merge with another company.
 
 (b) The Credit Facilities:
 
  In April 1995, the Company reached agreement with a syndicate of commercial
banks for an aggregate of $250,000 of revolving credit facilities (the "Credit
Facilities" or the "MFS Credit Facility" and the "MFS Telecom Credit
Facility"). The Credit Facilities provide for borrowings of $150,000 by MFS
Communications Company, Inc. and $100,000 by MFS Telecom. The commitments of
the banks under the Credit Facilities shall be reduced quarterly starting July
31, 1998 through April 30, 2000. The obligations of the Company under the MFS
Credit Facility have been guaranteed by substantially all of the Company's
subsidiaries and collateralized by a security interest in the capital stock of
substantially all of the Company's U.S. subsidiaries and a security interest
in several franchise agreements held by certain of the Company's subsidiaries.
The obligations of MFS Telecom under the Telecom Credit Facility have been
guaranteed by the Company and certain of the Company's subsidiaries and
collateralized by a security interest in the capital stock of substantially
all of MFS Telecom's U.S. operating subsidiaries. The Company may repay any
amounts borrowed under the Credit Facilities without premium or penalty at any
time.
 
  The Credit Facilities provide for interest at a variable rate and a variable
commitment fee on any unused balances. The Credit Facilities contain certain
financial covenants and certain restrictions on the Company's ability to incur
debt, sell assets, pay cash dividends and enter into transactions with
affiliates, among other things. Borrowings under the MFS Telecom Credit
Facility are to be used only for the construction and acquisition of
telecommunications assets, as defined in the agreement.
 
 (c) The Vendor Credit Facilities:
 
  In July 1995, the Company established two credit facilities to borrow up to
an aggregate of $120 million for purchases of switching equipment through mid-
1997 (the "Vendor Credit Facilities"). The facilities are collateralized by
the purchased equipment and partially guaranteed by the Swedish Export Credits
Guarantee Board and the equipment manufacturer. Borrowings under the Vendor
Credit Facilities will be repaid under various schedules, through 2002. The
Company may repay any amounts borrowed under the facilities without premium or
penalty at any time.
 
  The Vendor Credit Facilities provide for interest at a variable rate and a
commitment fee on any unused balances. The Vendor Credit Facilities contain
certain financial covenants and other restrictions similar to the Credit
Facilities.
 
 (d) The Notes Payable:
 
  In April 1995, the Company extended the maturity dates on the Notes Payable
to bank from 1995 to 1999. In addition, in connection with an acquisition in
1995, the Company assumed the Note Payable to credit corporation.

6. NOTES PAYABLE AND LONG-TERM DEBT (CONTINUED):
 
 (e) Other Debt:
 
  Subsequent to year end, the Company entered into a $20,000 loan agreement
with an equipment manufacturer and a bank. The loan, which includes interest
at a variable rate, must be used to purchase equipment supplied by the
manufacturer. The loan must be repaid in semi-annual installments of $2,000
starting June 20, 1996, and is collateralized by the equipment purchased. The
agreement contains certain financial covenants and restrictions similar to the
Credit Facilities.
 
  Subsequent to year end the Company issued Senior Discount Notes (the "1996
Senior Discount Notes") and recorded the net proceeds, exclusive of
transaction costs, of approximately $600 million as long-term debt. The
Company will accrue to the principal amount of the 1996 Senior Discount Notes
of $924,000 through January 2006. Cash interest will not accrue on the 1996
Senior Discount Notes prior to January 15, 2001 however, the Company may elect
to commence the accrual of cash interest at any time prior to that date.
Commencing July 15, 2001, cash interest will be payable semi-annually. The
Company utilized a portion of the proceeds from the 1996 Senior Discount Notes
to repay the outstanding balances under the Credit Facilities and a portion of
the Notes Payable to bank. In connection with the issuance of the 1996 Senior
Discount Notes, certain amendments to the financial covenants of the Credit
Facilities and the Vendor Credit Facilities were made which, among other
things, allowed the Company to issue the 1996 Senior Discount Notes.
 
7. LEASES:
 
  Capitalized leases consist of leases of electronic telecommunications
equipment. The Company is also leasing premises under various operating leases
which, in addition to rental payments, require payments for insurance,
maintenance, property taxes and other executory costs related to the leases.
Certain leases provide for adjustments in lease cost based upon adjustments in
the consumer price index and increases in the landlord's management costs. The
lease agreements have various expiration dates and renewal options through
2009.
 
  Future minimum payments by year and in the aggregate, under the capital
leases and non cancelable operating leases with initial or remaining terms of
one year or more consist of the following at December 31, 1995:

8. COMMITMENTS AND CONTINGENCIES:
 
  Under the terms of stockholder agreements, from time to time, minority
stockholders in certain subsidiaries have the option to put shares to the
Company at a purchase price equal to an appraised value of such shares.
 
  The Company has issued standby letters of credit to various city
governmental agencies and building lessors, amounting to approximately $10,341
at December 31, 1995. It is management's belief that the underlying
obligations will be met in the normal course of business without material
adverse effect on the Company's financial position.
 
  The Company is also obligated under rights-of-way and franchise agreements
with various entities for the use of their rights-of-way for the installation
of its telecommunications systems.
 
  In 1994, several former stockholders of MFS Telecom, a subsidiary of the
Company, filed a lawsuit against the Company, KDG, and the Company's chief
executive officer regarding the sale of their shares of MFS Telecom to the
Company in September 1992. The plaintiffs allege that certain information was
concealed from them, which caused them to sell their shares at an inadequate
price. KDG has agreed to indemnify the Company against any claims asserted by
the former stockholders.
 
  The Company is also involved in various other claims and regulatory
proceedings incidental to its business. Management believes that any resulting
liability beyond that provided should not materially affect the Company's
financial position, results of operations or cash flows.
 
9. INCOME TAXES:
 
  Prior to the Company's initial public offering in May 1993 the Company was
included in the consolidated income tax returns of PKS. Income taxes were
recognized on a separate return basis as if the Company filed its own income
tax returns.
 
  The Company and its parent entered into the Tax Sharing Agreement pursuant
to which the parent has agreed to indemnify the Company against federal, state
or local income tax liabilities of the consolidated or combined group of which
the parent is the common parent for taxable periods beginning on or after
January 1, 1993 during which the Company was a member of such group. In
addition, pursuant to the Tax Sharing Agreement, for all taxable periods
beginning on or after January 1, 1993, the Company would pay to the parent
amounts equal to the taxes that the Company would otherwise have to pay if it
were to file separate federal, state or local income tax returns, except that
the Company will not be entitled to carry forward certain net operating losses
generated prior to January 1, 1993. As a result of the Company's initial
public offering in 1993, the Tax Sharing Agreement applies only to the
January-May 1993 period for federal income tax purposes. The Company will
recognize tax benefits on losses incurred subsequent to January 1, 1993 only
to the extent the Company can utilize those benefits.
 
  Loss before income taxes is comprised of a loss of approximately $251,000
and $139,000 from domestic operations and approximately $16,000 and $14,000
from foreign operations in 1995 and 1994, respectively. Substantially all of
the Company's loss before income taxes prior to 1994 was derived from domestic
operations.

  At December 31, 1995, the Company had net operating loss carryforwards for
income tax purposes of approximately $444,000 which expire in years 1997

deferred tax assets due to the uncertainty of realizing the benefit of the
loss carryforwards.

10. SERIES A PREFERRED STOCK:
 
  In May 1995, the Company issued 9,500,000 Depositary Shares (the "Depositary
Shares"), each representing a one one-hundredth interest in a share of Series
A 8% cumulative convertible preferred stock (the "Series A Preferred Stock"),
in a public offering. The proceeds of the offering, net of expenses, was
$306,455. The Depositary Shares are mandatorily convertible into an aggregate
of 19,000,000 shares of common stock. The Depositary Shares are also
redeemable at the option of the Company into shares of common stock on or
after May 31, 1998 at a ratio that will vary depending upon certain factors,
including the market price of the common stock at the time of redemption and
the status of dividend payments. The Depositary Shares are also convertible at
the option of the holder at any time at a rate of 163.94 shares of common
stock for each share of Series A Preferred Stock (equivalent to a conversion
price of $20.43 per share of common stock), subject to certain adjustments.
 
  The Depositary Shares are entitled to receive dividends, when, as, and if
they are declared by the Board of Directors, accruing at the rate of $2.68 per
share per annum, payable quarterly in arrears on each February 28, March 31,
August 31 and November 30. Dividends are payable in cash or in shares of
common stock, at the election of the Company. Certain of the Company's debt
agreements restrict the Company's ability to pay cash dividends, and as a
result, the Company does not anticipate that it will pay cash dividends on the
Series A Preferred Stock for the foreseeable future. The Company paid the
dividends on August 31 and November 30, 1995 in common stock valued at
$14,773.
 
  The Depositary Shares are entitled to vote on the basis of .1000 of a vote
for each Depositary Share held (equivalent to 10 votes for each share of
Series A Preferred Stock). The Series A Preferred Stock has a liquidation
preference equal to the greater of (i) the sum of (a) $3,350 per share and (b)
all accrued and unpaid dividends thereon to the date of liquidation and (ii)
the value of the shares of the Company's common stock into which such Series A
Preferred Stock are convertible on the date of liquidation.
 
11. SPIN-OFF:
 
  Pursuant to a planned restructuring of PKS' ownership in the Company's
capital stock, on September 30, 1995, the Company issued 15,000,000 shares of
Series B, 7 3/4% cumulative convertible preferred stock (the "Series B
Preferred Stock") to a wholly owned subsidiary of PKS in exchange for
5,800,000 shares of the Company's common stock, which are being held in
treasury. Also pursuant to that restructuring, PKS purchased $1,000 of the
Company's common stock and then distributed all of its shares of the Company's
common stock and the shares of Series B Preferred Stock to certain of its
stockholders. The Series B Preferred Stock received by PKS' stockholders are
subject to certain restrictions regarding sale or transfer through September
30, 2001. The common stock received and the Series B Preferred Stock issued in
the exchange have been accounted for based upon the market value of the common
stock on September 30, 1995.
 
  The Series B Preferred Stock is convertible into shares of common stock at
any time after the first anniversary of the date of issuance at a conversion
price of $21.563 (an effective conversion rate of 0.0463768 shares of common
stock for each share of Series B Preferred Stock). Dividends on the Series B
Preferred Stock accrue at the rate of 7 3/4% per annum and are payable in
cash. Dividends will be paid only when, as and if declared by the Board of
Directors of the Company. Certain of the Company's debt agreements restrict
the Company's ability to pay cash dividends, and as a result the Company
anticipates that, in the near future, dividends on the Series B Preferred
Stock will not be declared but will continue to accrue. Upon conversion,
accrued but unpaid dividends are payable in cash or shares of common stock at
the Company's election. At December 31, 1995, the Company has recognized
undeclared dividends of $291, or $.02 per Series B preferred share.
 
  Shares of Series B Preferred Stock are also redeemable at the option of the
Company at any time after September 30, 2001 at a redemption price of $1.00
per share, plus accrued and unpaid dividends. The redemption price will be
payable in cash or shares of the Company's common stock at the Company's
election.

11. SPIN-OFF (CONTINUED):
 
  Each share of Series B Preferred Stock has the right to ten votes on all
matters presented to the Company's stockholders, however the shares are
subject to an irrevocable proxy that has been granted to the Secretary and
Assistant Secretary of the Company on all matters other than the election of
directors and matters as to which holders of the Series B Preferred Stock vote
as a separate class. That proxy requires the Secretary and Assistant Secretary
of the Company to vote all of the shares of Series B Preferred Stock in
proportion to the vote of the holders of the Company's common stock. The
Series B Preferred Stock has a liquidation preference over Junior Stock, as
defined, of $1.00 per share, plus an amount equal to unpaid dividends thereon,
including accrued dividends, whether or not declared.
 
12. COMMON STOCK WARRANTS:
 
  The Company entered into an agreement on June 8, 1993 to issue 1,500,000
common stock warrants to an investment bank in consideration for the provision
of financial advisory services to the Company over a three-year period. The
warrants vest quarterly through June 7, 1996, and are exercisable at $13.125
per share during the five-year period following the date each portion vests
and becomes exercisable. The fair value of the warrants as of June 8, 1993 has
been accounted for within stockholders' equity as additional paid-in capital,
with an offsetting deferred charge to equity and will be amortized over the
three-year vesting period. In the event of a change in control as defined in
the agreement, the warrants immediately vest and become exercisable.
 
13. STOCKHOLDER RIGHTS PLAN:
 
  In September 1995, the Company executed a Rights Agreement that provides for
the issuance of preferred stock purchase rights which expire in October 2005.
The rights generally will be exercisable and transferable apart from the
common stock only after the tenth day following public disclosure that a
person or group has acquired beneficial ownership of 15% or more of the common
stock or, the tenth business day after the date on which a person commences a
tender or exchange offer upon consummation of which such person or group would
beneficially own 15% or more of the common stock of the Company.
 
  If any person becomes the beneficial owner of 15% or more of the Company's
common stock other than pursuant to an offer for all shares which is fair to
and otherwise in the best interests of the Company and its subsidiaries, then
each right not owned by a 15% or more stockholder or certain related parties
will entitle the holder to purchase shares of common stock of the Company (or,
in certain circumstances as determined by the Board of Directors of the
Company, cash, other property, or other securities) having a value equal to
twice the right's exercise price. The rights may not be exercised while they
are redeemable . The Company is generally entitled to redeem the rights at
$.01 per right at any time until the tenth day following public disclosure
that a person or group has become the beneficial owner of 15% or more of the
Company's common stock.
 
  In addition, if, after any person has become a 15%-or-more stockholder, the
Company is involved in a merger or other business combination transaction with
another person in which its common stock is changed or converted, or sells 50%
or more of its assets or earning power to another person, each right will
entitle its holder to purchase, at the right's then-current exercise price,
shares of common stock of such other person having a value of twice the
right's exercise price.
 
14. SHELF REGISTRATION:
  The Company has filed a shelf Registration Statement on Form S-3 with the
Securities and Exchange Commission for the sale, from time to time, of one or
more series of unsecured debt or equity securities having an aggregate value
of $1.0 billion. In January 1996, the Company issued the 1996 Senior Discount
Notes which represented a partial drawdown of approximately $600 million on
the shelf registration.

15. EMPLOYEE BENEFIT PLANS:
 
 (a) 401(k) Plan:
 
  The Company administers a 401(k) Plan whereby eligible employees may
voluntarily contribute a percentage of compensation. The Company has not
contributed to the plan. Full-time employees who have attained 21 years of age
are eligible to participate.
 
 (b) Stock Option Plans:
 
  On November 23, 1992, the Board of Directors adopted the 1992 Stock Plan,
which authorizes, among other things, the grant of options at not less than
100% of the fair market value at the date of the option grant. On that date an
aggregate of 12,000,000 shares of common stock were reserved for the exercise
of nonqualified stock options. Effective August 31, 1993, the Board of
Directors adopted the 1993 Stock Plan, which authorizes the grant of options
at not less than 100% of the fair market value at the date of the option
grant. The Company has registered 20,000,000 shares of common stock for the
grant of options under the 1993 plan. The Compensation Committee of the Board
of Directors administers the stock plans. Options vest over a five-year
period. Certain non-executive employees have received credit for years of past
service under the 1992 stock plan.
 
  Information regarding the Company's stock option plans is summarized below:

 (c) Shareworks:
 
  Effective October 1995, the Company implemented a new employee benefit plan
which is comprised of a grant plan and a match plan jointly known as
Shareworks. The plan was offered to each domestic employee hired after
September 1, 1995, and also made available to all current employees that
choose to be ineligible for future grants under the Company's Stock Option
Plans. The grant plan enables the Company to grant shares of the Company's
common stock to eligible employees based upon a percentage of the employee's
eligible pay, up to 5%. The original grant will vest after three years with
any additional grants vesting immediately once the initial three year period
has been met.
 
  The match plan allows eligible employees to defer between 1% and 10% of
eligible pay to purchase common stock of the Company at the stock price on
each pay period date. The Company will match the shares purchased by the
employee on a one-for-one basis. The stock which is credited to each
employee's account to match the employee's purchase during any calendar
quarter, vests three years after the end of that quarter. The amount deferred
by employees for purchases of stock through December 31, 1995 was $1,352.
 
 (d) Shareworks Plus:
 
  Subsequent to year end the Company implemented a new employee stock
compensation plan which grants stock options to certain key executive
employees under a plan known as Shareworks Plus. Under this plan, the value
received by the employee upon exercise is determined by the rate of increase
in the Company's stock compared to the rate of increase in the S&P 500, a
common composite measurement of the stock price of a group of companies. If
the stock price of the Company's common stock does not increase faster than
the S&P, or if the Company's stock price decreases, the value to be received
by the employee upon exercise is $0. If the stock price of the Company's
common stock increases at a rate faster than the S&P 500 the value received by
the employee upon exercise, which will normally be paid in common stock of the
Company, increases. The first grant of approximately 450,000 options under
Shareworks Plus, which are immediately vested, was made on January 1, 1996.
Subject to the approval of the Company's Compensation Committee of the Board
of Directors, additional grants will be made quarterly.
 
 (e) Accounting for Stock-Based Compensation:
 
  In October 1995, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 123 ("SFAS 123"), Accounting for Stock-
Based Compensation. SFAS 123 encourages entities to adopt a fair value based
method of accounting for employee stock compensation plans, however it also
allows an entity to continue to measure compensation cost for those plans
using the intrinsic value based method of accounting. Under the intrinsic
value based method, many companies, including MFS, have not recognized
compensation cost for many of their stock compensation plans. Under the fair
value based method, many companies would recognize compensation costs for
those same plans.
 
  The Company plans to adopt SFAS 123 in the first quarter of 1996. While the
Company has not yet determined the total effect of adopting SFAS 123, it
believes that the adoption of the standard will result in material non-cash
charges to operations in 1996 and thereafter. The amount of the non-cash
charge will be dependent upon a number of factors, including the number of
options granted and the fair value estimated at the time of grant.

16.  ACQUISITIONS:
 
  In 1995, the Company acquired all of the issued and outstanding shares of
capital stock of companies that provide telecommunications services in
Richmond, Virginia, Denver, Colorado and White Plains, New York. The total
cost of the acquisitions was approximately $18,567, excluding transaction
costs and liabilities assumed. The cost of one of these acquisitions included
the issuance of 342,720 shares of the Company's common stock valued at $5,912.
These operations have been integrated into MFS Telecom. The effect on the
Company's operations as a result of these acquisitions was not significant.
 
  Effective November 14, 1994, the Company purchased all the outstanding stock
of RealCom Office Communications, Inc. ("RealCom"). RealCom was a Shared
Tenant Services company that provides telecommunications services, including
long distance, equipment and outsourcing. The total cost of the acquisition
was approximately $60,302, excluding transaction costs and liabilities
assumed. Included in the cost of the acquisition were 2,720,606 shares of the
Company's common stock valued at $53,052. RealCom operations have been
integrated into MFS Intelenet.
 
  Effective November 1, 1994, the Company purchased all the outstanding stock
of Cylix Communications Corporation ("Cylix"). Cylix provides data
communications services by providing connectivity for IBM compatible hosts to
remote sites. The total cost of the acquisition was approximately $8,240,
excluding transaction costs and liabilities assumed. Included in the cost of
the acquisition were 355,490 shares of the Company's common stock valued at
$5,990. Cylix operations have been integrated into MFS Datanet.
 
  Effective May 18, 1994, the Company purchased the common stock and all stock
options of Centex Telemanagement, Inc. ("Centex"). Centex provides
telecommunications management services for small and medium-sized businesses.
The total cost of the acquisition was approximately $202,083, excluding
transaction costs and liabilities assumed. Centex operations have been
integrated into MFS Intelenet.
 
  In the first quarter of 1994, the Company acquired all of the issued and
outstanding shares of a company that provided telecommunications services in
Rochester, Albany and Buffalo, New York and acquired cable and various rights-
of-way agreements from a company which provided the base for the Company's
network in St. Louis, Missouri. These operations have been integrated into MFS
Telecom.
 
  These acquisitions have been accounted for as purchases and accordingly, the
acquired assets and liabilities were recorded at their estimated fair values
at the date of the acquisition, and the results of operations have been
included in the accompanying financial statements since the dates of
acquisition. The total purchase price in excess of the fair market value of
the net assets acquired was recorded as goodwill. The goodwill is being
amortized on a straight-line basis over a 40-year life.

16. ACQUISITIONS (CONTINUED):
 
  The following unaudited pro forma information shows the results of the
Company as though the acquisitions in 1994 occurred as of the beginning of
each period indicated. These results include certain adjustments consistent
with the Company's accounting policies related to revenue recognition and
amortization of intangible assets. These results are not necessarily
indicative of the results that actually would have been attained if the
acquisitions had been in effect at the beginning of each period or which may
be attained in the future.

  In 1994, the Company recorded $24,514 of additional goodwill relating to the
settlement of a deferred purchase price adjustment that arose prior to 1994.
In April 1990, the Company acquired 80% of the voting stock of Chicago Fiber
Optic Corporation, now doing business as Metropolitan Fiber Systems of
Chicago, Inc. ("MFS Chicago"). The acquisition was accounted for as a
purchase. A portion of the purchase price of the stock acquired was to be
based upon the fair market value of MFS Chicago in April 1993. During 1991,
the Company acquired an additional 10% of the voting stock of MFS Chicago for
a deferred purchase price based upon the MFS Chicago fair market value as of
April 1993. The deferred purchase price associated with these purchases of MFS
Chicago stock was assumed by KDG, the Company's majority stockholder, without
recourse to the Company in 1993 and was settled in the first quarter of 1994.
The Company recorded the settlement as goodwill and a capital contribution by
KDG.
 
  The Company also acquired the interest of certain minority shareholders of
its subsidiaries during 1995 and 1994.

20. STOCK SPLIT:
 
  On April 1, 1996 the Board of Directors declared a two-for-one common stock
split. The stock split was effected in the form of a stock dividend that was
payable to stockholders of record on April 16, 1996. The conversion features
of the Company's Series A and Series B Preferred stock were adjusted pursuant
to their terms to maintain the proportionate rights of those preferred stocks.
In this report, all per share amounts and numbers of shares have been restated
to reflect the stock split.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                 (DOLLARS IN THOUSANDS, EXCEPT PER SHARE DATA)
                                  (UNAUDITED)
 
1. BASIS OF PRESENTATION:
 
  All financial statements contained herein are unaudited and, in the opinion
of management, contain all adjustments necessary for a fair presentation of
financial position and results of operations and cash flows for the periods
presented. Such adjustments consist only of normal recurring items. The
Company's accounting policies and certain other disclosures are set forth in
the notes to the annual consolidated financial statements.
 
  Where appropriate, items within the consolidated financial statements have
been reclassified from the previous year to conform to current year
presentation.
 
2. INCOME TAXES:
 
  The income tax expense of $100 for the three months ended March 31, 1996 and
1995 resulted from estimated state and foreign tax liabilities.
 
3. CAPITAL STOCK:
 
  In the first quarter of 1996, the Company retired the shares of common stock
that were held in treasury. The value of the treasury shares reduced common
stock, paid in capital and increased the accumulated deficit upon retirement.
In addition, the Company's stockholders approved an amendment to the Company's
restated certificate of incorporation to increase the number of authorized
shares of common stock to 400,000,000.
 
  On April 1, 1996 the Board of Directors declared a two-for-one common stock
split. The stock split was effected in the form of a stock dividend that was
payable to stockholders of record on April 16, 1996. The conversion features
of the Company's Series A and Series B preferred stock were adjusted pursuant
to their terms to maintain the proportionate rights of those preferred stocks.
In this report, all per share amounts and numbers of shares have been restated
to reflect the stock split. In addition, an amount equal to the $.01 par value
of the shares outstanding at March 31, 1996 has been transferred from
additional paid in capital to common stock.
 
4. LOSS PER SHARE:
 
  Loss per common share has been computed using the weighted average number of
shares outstanding for each period. The number of shares used in computing
loss per share, which have been adjusted due to the two-for-one stock split,
was 125,017,000 for the three months ended March 31, 1996 and 128,729,000 for
the three months ended March 31, 1995.
 
5. LONG TERM DEBT:
 
 (a) Loan Agreement:
 
  On January 2, 1996, the Company entered into a $20,000 loan agreement with
an equipment manufacturer and a bank. The loans under the agreement, which
include interest at a variable rate, will be used to purchase equipment
supplied by the manufacturer. The loans must be repaid in semi-annual
principal installments of $2,000 starting June 20, 1996, subject to certain
adjustments, and are collateralized by the equipment purchased. The agreement
contains certain covenants and restrictions similar to the Company's Credit
Facilities. The Company may prepay any amounts under the agreement without
premium or penalty at any time.

5. LONG TERM DEBT (CONTINUED):
 
 (b) The 1996 Senior Discount Notes:
 
  The Company issued 8 7/8% Senior Discount Notes on January 18, 1996 (the
"1996 Senior Discount Notes") and recorded the net proceeds, exclusive of
transaction costs, of approximately $600,000 as long-term debt. The Company is
accruing to the principal amount of the 1996 Senior Discount Notes of $924,000
through January 15, 2001. Cash interest will not accrue on the 1996 Senior
Discount Notes prior to January 15, 2001, however, the Company may elect to
commence the accrual of cash interest at any time prior to that date.
Commencing July 15, 2001, cash interest will be payable semi-annually.
 
  The 1996 Senior Discount Notes mature on January 15, 2006. On or after
January 15, 2001, the 1996 Senior Discount Notes will be redeemable at the
option of the Company, in whole at any time or in part from time to time, at
the following prices (expressed in percentages of the principal amount thereof
at stated maturity) if redeemed during the twelve months beginning January 15
of the years indicated below, in each case together with interest accrued to
the redemption date:
 
<TABLE>

            YEAR                               PERCENTAGE

            2003..............................  101.11%
            2004 and thereafter...............  100.00%
</TABLE>
 
  In addition, under certain conditions related to a change in control of the
Company, the Company may be required to repurchase all or any part of the 1996
Senior Discount Notes as stipulated in the note agreement. The 1996 Senior
Discount Notes are senior unsecured obligations of the Company, with a ranking
equal to the 1994 Senior Discount Notes, and are subordinated to all current
and future indebtedness of the Company's subsidiaries, including trade
payables. The 1996 Senior Discount Notes contain certain covenants which,
among other things, restrict the ability of the Company to incur debt, create
liens, enter into sale and leaseback transactions, pay dividends, make certain
restricted payments, enter into transactions with affiliates, and sell assets
or merge with or into another company.
 
6. STOCK COMPENSATION PROGRAMS:
 
  The Company has three stock based compensation programs at March 31, 1996.
The programs are described as follows:
 
 (a) Stock Option Plans:
 
  The 1992 and 1993 Stock Plans authorize, among other things, the grant of
options at not less than 100% of the fair market value at the date of the
option grant. The Compensation Committee of the Board of Directors administers
the stock plans. Options vest over a five-year period and are generally
exercisable up to five years after the grant is completely vested. No options
were granted under the 1992 and 1993 plans during the first quarter of 1996.
 
 (b) Shareworks:
 
  In 1995 the Company implemented an employee benefit plan which is comprised
of a grant plan and a match plan jointly known as Shareworks. The grant plan
enables the Company to grant shares of the Company's common stock to eligible
employees based upon a percentage of the employee's eligible pay, up to 5%.
The original grant vests after three years with any additional grants vesting

                                  (UNAUDITED)
6. STOCK COMPENSATION PROGRAMS (CONTINUED):
 
immediately once the initial three year period has been met. On December 29,
1995, the Company granted approximately 64,000 shares of stock under this part
of the plan.
 
  The match plan allows eligible employees to defer between 1% and 10% of
eligible pay to purchase common stock of the Company at the stock price on
each pay period date. The Company matches the shares purchased by the employee
on a one-for-one basis. The stock which is credited to each employee's account
to match the employee's purchase during any calendar quarter, vests three
years after the end of that quarter. The amount deferred by employees for
purchases of stock from January 1, 1996 through March 31, 1996 was $1,179.
 
(c) Shareworks Plus:
 
  In 1996 the Company implemented a new employee stock compensation program
which grants stock options with a four-year life and immediate vesting to
certain key executive employees under a program known as Shareworks Plus.
Under this program, the value received by the employee upon exercise is
determined by the rate of increase in the Company's stock price compared to
the rate of increase in the S&P 500 index, measured from the grant date. If
the Company's common stock price performance is at or below the price
performance of the S&P 500 index, or under certain other circumstances defined
in the program, the value to be received by the employee upon exercise is $0.
If the Company's common stock price performance is above the price performance
of the S&P 500 index the value received by the employee upon exercise, which
will normally be paid in common stock of the Company, increases. In the first
quarter, the first grant of options under Shareworks Plus was made. Subject to
the approval of the Company's Compensation Committee of the Board of
Directors, additional grants will be made quarterly. Terms of the Shareworks
Plus program may be modified from time to time by the Compensation Committee
of the Board of Directors.
 
  In the first quarter of 1996, the Company adopted the accounting provisions
of Statement of Financial Accounting Standards No. 123, Accounting for Stock-
Based Compensation (SFAS 123). SFAS 123 encourages entities to adopt the fair
value method of accounting for their stock-based compensation plans. Under the
fair value based method, compensation cost for stock based compensation plans
is measured at the grant date based on the fair value of the award and is
recognized over the service period, which for the Company is the vesting
period. For the Company's Shareworks Plus program, the fair value was
determined using option-pricing models that take into account the stock price
at the grant date, the exercise price, a two year expected life for the
option, an estimated volatility of 30% for the Company's stock price, no
expected dividends, and a risk-free interest rate of 5.27% over the expected
life of the options. For the Company's other stock compensation plan,
Shareworks, the fair value of the match shares was determined by reference to
the market value of the stock that was purchased by the employee and the fair
value of the grant shares was determined by the market value of the stock at
the grant date.
 
  The Company recognized compensation expense of $396 related to the
Shareworks plan and $2,945 related to the Shareworks Plus program in the first
quarter of 1996. The pro forma impact of adopting the fair value method of
accounting in the first quarter of 1995 was immaterial primarily because the
number of options granted in the first quarter of 1995 under the 1992 and 1993
Stock Option Plans were not material and the fact that the Shareworks and
Shareworks Plus programs were not yet implemented. During the initial phase-in
period, the effects of applying SFAS 123 for recognizing compensation cost may
not be representative of the effects on reported net loss or income

                                  (UNAUDITED)
6. STOCK COMPENSATION PROGRAMS (CONTINUED):
 
for future quarters or years because the options in the Stock Option Plans and
the match and grant shares made under the Shareworks program vest over several
years and additional awards will be made in the future.
 
  Under the Company's Shareworks Plus program, the Company granted 453,004
options during the first quarter of 1996, at an initial exercise price of
$26.62. A total of 55,930 options were exercised during the quarter. The fair
value of the options granted was estimated to be $6.50 per share.
 
7. COMMITMENTS AND CONTINGENCIES:
 
  In 1994, several former stockholders of MFS Telecom, a subsidiary of the
Company, filed a lawsuit against the Company, the Company's former majority
stockholder, Kiewit Diversified Group Inc. ("KDG"), and the Company's chief
executive officer regarding the sale of their shares of MFS Telecom to the
Company in September 1992. The plaintiffs allege that certain information was
concealed from them, which caused them to sell their shares at an inadequate
price. KDG has agreed to indemnify the Company against any claims asserted by
the former stockholders.
 
  The Company is also involved in various other claims and regulatory
proceedings incidental to its business. Management believes that any resulting
liability beyond that provided should not materially affect the Company's
financial position, results of operations or cash flows.
 
8. SUBSEQUENT EVENT--MERGER AGREEMENT:
 
  On April 30, 1996, the Company announced that it had executed a merger
agreement with UUNET Technologies, Inc. ("UUNET"). Under the terms of the
agreement, which includes a fixed conversion ratio, each share of UUNET stock
will be converted into 1.777776 shares of the Company's common stock on a
post-split basis. The transaction value is approximately $2 billion based on
the Company's stock price at the date of the announcement. The merger
agreement was unanimously approved by the Board of Directors of each company
and the transaction will be recommended by each board to its shareholders. In
addition, shareholders of UUNET owning approximately 62 percent of the
outstanding shares and shareholders of the Company owning approximately 12
percent of the outstanding shares have committed to vote in favor of the
transaction.
 
  The Company anticipates that a substantial portion of the purchase price
will be allocated to intangible assets including goodwill and expects to
amortize those intangible assets over a period of up to five years. The actual
allocation of the purchase price and determination of useful lives will be
made after further evaluation.

31, 1994 and 1995, and the related consolidated statements of operations,
stockholders' equity and cash flows for each of the three years in the period

the Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform an audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of UUNET Technologies, Inc.,
and Subsidiaries, as of December 31, 1994 and 1995, and the results of their
operations and their cash flows for each of the three years in the period

1. THE COMPANY AND SIGNIFICANT ACCOUNTING POLICIES:
 
 Organization and Operations
 
  UUNET Technologies, Inc. ("UUNET") was incorporated in the state of Delaware
in 1990. UUNET and its wholly-owned subsidiaries are collectively referred to
herein as the "Company." The Company is a leading worldwide provider of a
comprehensive range of Internet access options, applications, and consulting
services to businesses, professionals and on-line services providers. The
Company's Internet access options provide dedicated and dial-up Internet
access. Other applications and services include Web server hosting and
integration services, client software and security products, training, and
network integration and consulting services. In addition, the Company
developed, operates and maintains the high speed dial-up network for Microsoft
Corporation ("Microsoft").
 
  The Company has incurred cumulative losses of approximately $28.3 million
during the three-year period ended December 31, 1995. The Company's operations
are subject to certain risks and uncertainties including, among others, actual
and potential competition by entities with greater financial resources,
experience and market presence than the Company, risks associated with
consolidation in the industry, risks associated with acquisitions and
international expansion, the need to manage growth and expansion, certain
technology and regulatory risks, and dependence upon sole and limited source
suppliers. See "Risk Factors" elsewhere in this Prospectus.
 
 Acquisition of Unipalm
 
  On November 15, 1995, UUNET acquired Unipalm Group plc ("Unipalm"), a
provider of Internet access options, networking software, training and
consulting services in the United Kingdom and Europe. Under the terms of the
tender offer made by UUNET, Unipalm shareholders received 0.1543 of a share of
UUNET Common Stock for each Unipalm share. Each holder of a Unipalm option
received 0.1543 of a share of UUNET Common Stock for each option, after taking
into account the fair market value of such options. Accordingly, UUNET issued
3,338,009 shares of its Common Stock for all of the outstanding shares of
Unipalm stock and options to acquire shares of Unipalm stock, and paid cash
for fractional shares. The acquisition was accounted for as a pooling of
interests and, as such, UUNET's financial statements have been restated to
include the results of Unipalm for all periods presented.
 
  Combined and separate results of UUNET and Unipalm during the periods
preceding the acquisition are as follows (in thousands):

1. THE COMPANY AND SIGNIFICANT ACCOUNTING POLICIES--(CONTINUED):
 
  Unipalm previously had an April 30 fiscal year-end. In order to conform
Unipalm's fiscal year-end to UUNET's calendar year-end, the statement of
operations for Unipalm for its fiscal year ended April 30, 1994 has been
combined with UUNET's statement of operations for its year ended December 31,
1993. The consolidated statement of operations for the year ended December 31,
1993 includes four months (January 1, 1994 through April 30, 1994) which are
also included in the consolidated statement of operations for the year ended
December 31, 1994. Accordingly, an adjustment has been made in the year ended
December 31, 1993 to retained earnings for the duplication of net income of
$127,000 for such four month period. Revenues of Unipalm for that four-month
period were approximately $6.1 million.
 
  In connection with the acquisition, the Company recorded one-time charges in
the fourth quarter of 1995 for acquisition-related costs of $11.1 million.
These costs consisted primarily of investment banking and professional fees,
and direct costs necessary to complete the transaction, including taxes and
printing and mailing costs.

  Subsequent to year end, UUNET acquired a 40% interest in the outstanding
capital of EUnet Deutschland GmbH ("EUnet Germany"), a provider of Internet
access options, applications and consulting services in Germany, for $1.6
million.
 
  In January 1996, UUNET and UUNET Canada, Inc. ("UUNET Canada") entered into
a letter of intent providing for an increase in UUNET's equity ownership of
UUNET Canada from 20% to 51%. On April 1, 1996, UUNET paid $3,585,329 in cash
and issued 27,079 shares of Common Stock for the additional 31 percent
interest in UUNET Canada.
 
 Initial Public Offerings
 
  In May 1995, UUNET completed an initial public offering of 5,433,750 shares
of Common Stock at a price per share of $14.00, of which 5,308,750 shares were
sold by UUNET and 125,000 shares were sold by a selling stockholder. After the
underwriting discounts, commissions and other expenses, net proceeds to UUNET
from the initial public offering were approximately $67.7 million. Upon the
closing of the initial public offering, all outstanding shares of Redeemable
Convertible Preferred Stock, including those shares issued in connection with
warrants for the purchase of 2,500,000 shares of Series E Preferred Stock
exercised immediately prior to the closing of the initial public offering,
automatically converted into Common Stock.
 
  In March 1994, Unipalm completed an initial public offering, with net
proceeds of approximately $8.0 million.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
1. THE COMPANY AND SIGNIFICANT ACCOUNTING POLICIES--(CONTINUED):
 
 Summary of Significant Accounting Policies
 
  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 revenues and expenses during
the reporting periods and reported amounts of assets and liabilities at the
date of the financial statements.
 
 Principles of Consolidation
 
  The consolidated financial statements include the accounts of UUNET and all
majority-owned subsidiaries. All material intercompany balances and
transactions have been eliminated. Investments in affiliated companies owned
20% or more are accounted for using the equity method, while investments in
companies owned less than 20% are accounted for using the cost method.
 
 Pro Forma Net Loss Per Common and Equivalent Share
 
  Pro forma net loss per common and equivalent share is based on the weighted
average number of shares outstanding during the periods presented. Pursuant to
the Securities and Exchange Commission Staff Accounting Bulletin No. 83, all
shares, options and warrants issued during the twelve months immediately
preceding the initial public offering were treated as if they had been
outstanding through March 31, 1995, using the treasury stock method and at a
per share price of $14.00, the initial public offering price. Subsequent to
March 31, 1995, the effects of warrants and options have not been considered
because the effect would be antidilutive.
 
  Earnings per share data prior to 1994 has been omitted because the automatic
conversion of the Redeemable Preferred Stock into Common Stock materially
changed UUNET's capitalization. Fully-diluted loss per share is not presented
as it would not materially differ from primary loss per share.
 
 Cash and Cash Equivalents
 
  The Company considers all highly liquid investments with an original
maturity of three months or less to be cash equivalents. Cash equivalents as
of December 31, 1994 consisted of U.S. Treasury Bills totaling approximately
$3.0 million. Cash equivalents as of December 31, 1995 consisted of short-term
commercial paper totaling approximately $8.7 million. As of December 31, 1994
and 1995, the fair value of these securities approximated cost.
 
 Concentrations of Cash and Accounts Receivable
 
  Financial instruments that potentially subject the Company to concentrations
of credit risk consist primarily of cash, cash equivalents and accounts
receivable. As of December 31, 1994, the Company had concentrations of cash in
two banks in the form of demand deposits and money market accounts, totaling
approximately $1.2 million at one bank and $5.8 million at the other bank. As
of December 31, 1995, the Company had concentrations of cash in a financial
institution money market fund of approximately $47.8 million and short-term
commercial paper of approximately $8.7 million. Also as of December 31, 1995,
UUNET had approximately $6.4 million in accounts receivable from Microsoft
(see Note 2). The Company believes that concentrations of credit risk with
respect to the remaining balance in accounts receivable are limited due to the
large number of entities comprising the Company's customer base. The Company
maintains an allowance for doubtful accounts for accounts receivable based
upon factors surrounding the credit risk of specific customers, historical
trends and other information.
 
 Inventories
 
  Inventories are stated at the lower of cost (first-in, first-out) or market,
and consist primarily of third party packaged software for resale.

software. The Company recognizes revenue on software product sales at the time
of delivery of the software, provided no significant future vendor obligations
exist. Customer support fees are deferred and recognized ratably over the
period of the service obligation.
 
 Cost of Revenues
 
  Internet services cost of revenues consists primarily of network
telecommunication costs, depreciation of network equipment, and the cost of
equipment and other products sold to customers. Software cost of revenues
consists primarily of packaged third party software costs.
 
 Network Operations and Support

 Recent Pronouncement
 
  In October 1995, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards ("SFAS") No. 123, "Accounting for Stock-
Based Compensation," which is effective for the Company's December 31, 1996
financial statements. SFAS No. 123 allows companies to either account for
stock-based compensation under the new provisions of SFAS No. 123 or under the
provisions of APB 25, but requires pro forma disclosure in the footnotes to
the financial statements as if the measurement provisions of SFAS 123 had been
adopted. The Company intends to continue accounting for its stock-based
compensation in accordance with the provisions of APB 25. As such, the
adoption of SFAS No. 123 will not impact the financial position or the results
of operations of the Company.
 
2. NETWORK AGREEMENTS:
 
  In December 1994, UUNET and Microsoft entered into a binding Memorandum of
Understanding, which was formalized into a definitive agreement (the
"Microsoft Agreement") in March 1995, for the development, operation and
maintenance of a high speed dial-up and ISDN TCP/IP access network (the "Dial-
Up Network"). Microsoft is obligated to reimburse UUNET for the cost of
constructing, maintaining and operating the Dial-Up Network, as well as pay a
management fee. The initial term of the Microsoft Agreement expires in March
2000, and it may be extended by Microsoft for an additional five-year term. In
March 1995 and as part of this strategic relationship, Microsoft purchased
1,664,000 shares of Series D Preferred Stock at $2.34 per share and in May
1995 exercised warrants to purchase 2.5 million shares of Series E Preferred
Stock at $5.00 per share (Notes 4 and 5). Upon closing of the initial public
offering, Microsoft's Preferred Stock was converted into 4,164,000 shares of
Common Stock. UUNET also entered into a $26.0 million loan agreement (Note 3)
with Microsoft, which allows UUNET to borrow funds to finance the purchase of
equipment for the construction of the Dial-Up Network. UUNET owns the network
equipment, subject to Microsoft's security interest. UUNET controls and
operates the Dial-Up Network and is able to sell a portion of the Dial-Up
Network capacity to other customers. Revenues from network services relating
to the Dial-Up Network represented 20.4% of total revenues for the year ended
December 31, 1995.

3. BORROWING ARRANGEMENTS:
 
  In December 1994, UUNET entered into a Credit Agreement with a bank to
provide for a $500,000 working capital line of credit ("Working Capital
Facility"), a $1,000,000 term facility ("Term Facility") and a $3,500,000
equipment facility ("Equipment Facility"). No amounts had been borrowed under
the Working Capital Facility, which expired in August 1995. The Term Facility
and Equipment Facility accrued interest at the bank's prime rate plus 1.75%
(10.5% at December 31, 1994). As of December 31, 1994, UUNET had borrowed the
$1,000,000 available under the Term Facility, which was repaid in June 1995.
During 1995, UUNET borrowed approximately $2,500,000 under the Equipment
Facility, all of which was repaid in June 1995. The Term Facility and
Equipment Facility expired in 1995.
 
  UUNET had notes payable to a related party (Note 7) that were due in monthly
installments through December 1995. Interest was fixed at rates of 8% or 10%,
and the notes were secured by specified network computer equipment of UUNET.
The notes were repaid in full in April 1995. Interest expense on these notes
was approximately $58,000, $33,000 and $4,000 in 1993, 1994 and 1995,
respectively. UUNET also had a note payable to a stockholder ($59,000 at
December 31, 1993) that was due and repaid in full in September 1994. Interest
accrued at 8% annually.
 
  In connection with the Microsoft Agreement, UUNET obtained a $26.0 million
equipment loan facility from Microsoft to finance equipment purchases in
conjunction with the construction of the Dial-Up Network. Principal and
interest, at the higher of the Applicable Federal Rate ("AFR") in effect on
the date of the Microsoft Agreement (7.74%) or the AFR in effect at the time
of the advance (5.79% as of December 31, 1995), are payable on each advance
quarterly over five years. Borrowings under the agreement are collateralized
by the equipment purchased. The carrying amount of the equipment loan facility
as of December 31, 1995 approximated fair market value. As of December 31,
1995, $10,501,000 was available for future advances under this facility.
 
  Notes payable outstanding consisted of the following (in thousands):

  In connection with the sale of Series A Preferred Stock in 1993, UUNET
issued warrants for the purchase of 3,300,000 shares of Series B Preferred
Stock at an exercise price of $1.00 per share. These warrants were exercised
during 1994, which resulted in gross proceeds of $3,300,000 to UUNET.
 
  As part of its strategic relationship with Microsoft, UUNET issued warrants
to Microsoft for the purchase of 2,500,000 shares of Series E Preferred Stock
in March 1995, at an exercise price of $5.00 per share. These warrants were
exercised in May 1995, which resulted in gross proceeds of $12.5 million to
UUNET.
 
5. STOCKHOLDERS' EQUITY:
 
  Microsoft has agreed that it will not directly or indirectly, except in
connection with any exercise of its right of first refusal, acquire shares of
Common Stock which when combined with its holdings, would result in Microsoft
owning greater than 18.11% of the then outstanding shares of Common Stock.
Microsoft also has agreed that it will not (i) enter into any voting agreement
or voting trust in connection with UUNET securities, (ii) form, or participate
in the formation of, any legal entity for the purpose of acquiring, voting or
disposing of UUNET securities, or (iii) act in concert with any person or
entity for the purpose of acquiring, holding, voting or disposing of UUNET
securities if by so acting Microsoft or such other person would be required to
file a Schedule 13D or 13G with the Securities and Exchange Commission or to
amend a previously filed Schedule 13D or 13G. UUNET has granted Microsoft a
right of first refusal and a right of first offer with respect to certain
acquisitions of more than 50 percent of the stock or assets of UUNET that may
be proposed in the future.

 Increase in Authorized Shares
 
  On January 31, 1996, the stockholders of UUNET at a Special Meeting of
Stockholders approved the increase in the authorized shares of Common Stock to
175,000,000, and UUNET filed a Certificate of Amendment to Restated
Certificate of Incorporation effecting such increase.
 
 Notes Receivable from Employees for Stock Purchases
 
  During 1994, certain employees of UUNET signed promissory notes in favor of
UUNET in conjunction with the purchase of stock under the terms and conditions
of UUNET's Incentive Stock Plan. The loans accrued interest at 8% annually and
were repaid during 1995.
 
 Incentive Stock and Equity Incentive Plans
 
  UUNET's Incentive Stock Plan (the "Option Plan") was adopted in 1990 and was
terminated on May 25, 1995. Under the Option Plan, the Board of Directors of
UUNET had the authority to grant incentive stock options, nonqualified stock
options and stock purchase rights at their discretion. Options granted under
the Option Plan are exercisable for periods up to ten years from the date of
grant. All options outstanding on the date of the Option Plan termination
remained exercisable in accordance with their terms.
 
  In 1995, UUNET adopted an Equity Incentive Plan (the "Incentive Plan"),
which provides for the grant of options, restricted stock, stock purchase
rights and performance shares to employees of the Company. Incentive stock
options and nonqualified stock options may be granted under the Incentive Plan
at exercise prices of 100% and at least 85%, respectively, of the fair market
value of Common Stock at the date of grant. Restricted stock awards consist of
shares of Common Stock with transfer restrictions that lapse over a period not
to exceed ten years. Stock purchase rights provide for the purchase of shares
of Common Stock at a price of at least 85% of the Common Stock's fair market
value. These stock purchase rights are generally exercisable for a period of
30 days after the date of grant. Performance awards of shares of Common Stock
may be granted for attainment of performance criteria determined by the Board
of Directors of UUNET. A total of 2,669,514 shares of Common Stock were
reserved for issuance under the Incentive Plan and the Option Plan. Any shares
not issued or reserved under the Option Plan become available for issuance
under the Incentive Plan. On January 31, 1996, the stockholders of UUNET at a
Special Meeting of Stockholders approved an increase in the number of shares
reserved for issuance under the Incentive Plan to 6,669,514.
 
  The following table summarizes all option and purchase right activity under
the Option Plan and the Incentive Plan for the three years ended December 31,

5. STOCKHOLDERS' EQUITY--(CONTINUED):
 
  As of December 31, 1994 and 1995, options to purchase 771,049 and 383,751
shares, respectively, were exercisable.
 
  Compensation equal to the difference between the assumed fair value of
Common Stock at the grant date and the exercise price of the options, if any,
is recognized ratably over the vesting period. Compensation expense related to
options granted in 1994 is approximately $207,000 and will be recognized over
the vesting period, which is generally five years. Compensation expense
relating to stock options was $1,000 in 1994 and $42,000 in 1995.
 
  Prior to the acquisition, Unipalm maintained its own stock option plan.
Stock options granted under the Unipalm plan were 194,078 and 39,347 in 1994
and 1995, respectively. The statement of stockholders' equity reflects the
exercise of vested options of 36,862 and 26,089 in 1994 and 1995,
respectively. All remaining Unipalm options outstanding at the time of the
acquisition were exchanged for UUNET Common Stock.
 
 1995 Performance Option Plan
 
  In 1995, UUNET adopted the 1995 Performance Option Plan (the "Performance
Plan") that provides for grants of nonqualified stock options to purchase
shares of Common Stock to employees of UUNET. Options to purchase 161,180
shares of Common Stock at an exercise price of $6.00 per share were granted in
February 1995, of which options to purchase 17,600 shares were canceled as of
December 31, 1995. Options granted under the Performance Plan were exercisable
on December 31, 2004, subject to acceleration provisions if the Company met
performance goals specified in the Performance Plan. Such performance goals
were achieved in 1995, resulting in the acceleration of vesting of the options
outstanding under the Performance Plan to March 31, 1996.
 
 Employee Stock Purchase Plan
 
  In 1995, UUNET adopted the Employee Stock Purchase Plan (the "Purchase
Plan") to permit employees of UUNET to purchase Common Stock at a price equal
to 85% of the lesser of the fair market value at the beginning or end of the
enrollment period as defined by the Purchase Plan. The first enrollment period
begins in February 1996.
 
 Nonemployee Directors Stock Option Plan
 
  In 1995, UUNET adopted the Nonemployee Directors Stock Option Plan (the
"Directors Plan") to grant nonqualified stock options to directors of UUNET
who are not employees. Eligible nonemployee directors will be granted an
option to purchase 7,500 shares of Common Stock on the day of their election,
re-election or appointment. The exercise price of all options will be equal to
the fair market value of Common Stock on the grant date. The options will vest
ratably over a three-year period. As of December 31, 1995, no options had been
granted under the Directors Plan.
 
 Reserved Shares
 
  The Company has reserved 6,843,565 shares of Common Stock for issuance
pursuant to stock plans as of January 31, 1996.

 Facilities Leases
 
  The Company leases and subleases office space at various locations with
expiration dates through April 2001. In 1994, UUNET terminated its then
existing office lease in conjunction with the signing of a sublease agreement
and recorded approximately $330,000 for costs associated with lease
termination and idle equipment during the lease termination period. During
1995, the Company recorded lease termination and idle equipment costs of
approximately $1.8 million classified as general and administrative expense in
the accompanying statements of operations as a result of consolidating
substantially all of Unipalm's operations into a new facility. Rent expense
for the years ended December 31, 1993, 1994 and 1995, including lease
termination and idle equipment costs, was approximately $828,000, $1,323,000

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
9. EMPLOYEE RETIREMENT PLAN:
 
  Effective January 1, 1995, UUNET adopted a 401(k) salary deferral plan (the
"401(k) Plan"). Employees of UUNET are eligible to participate in the 401(k)
Plan when they reach age 21 and have completed half of a year of service with
UUNET. The 401(k) Plan replaced a Simplified Employee Pension ("SEP") Plan,
which allowed UUNET to make discretionary contributions. Total expense related
to the SEP Plan was approximately $165,000 and $451,000 for the years ended
December 31, 1993 and 1994, respectively; no contribution was made during
1995. UUNET matched 1% of contributions made by eligible employees in 1995
under the 401(k) Plan, which expense totaled $71,000 for the year ended
December 31, 1995.
 
10. INCOME TAXES:
 
  The Company records income taxes in accordance with SFAS 109, "Accounting
for Income Taxes." The adoption of SFAS 109 by UUNET on January 1, 1993, had
no effect on the consolidated financial position or results of operations for
the year ended December 31, 1993.
 
  The components of the benefit (provision) for income taxes are as follows

  As of December 31, 1995, the Company had U.S. federal and foreign net
operating loss ("NOLs") of approximately $12,177,000 and $2,455,000,
respectively. The federal NOLs expire in years 2008 through 2010; foreign NOLs
may be utilized in future years to the extent of foreign income. The amount of
federal NOLs available to be used in any given year may be limited in the
event of significant changes in the ownership of UUNET. Management believes
that the prior ownership changes will not significantly limit the Company's
ability to use its NOLs. The Company has fully reserved its deferred tax
assets as of December 31, 1995.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  (UNAUDITED)
 
1. THE COMPANY AND SIGNIFICANT ACCOUNTING POLICIES:
 
  UUNET Technologies, Inc., together with its wholly-owned subsidiaries
("UUNET" or the "Company"), is a leading provider of a comprehensive range of
Internet access options, applications and consulting services to businesses,
professionals and on-line services providers.
 
  The condensed interim consolidated financial statements included herein have
been prepared by the Company, without audit, pursuant to the rules and
regulations of the Securities and Exchange Commission. Certain information and
footnote disclosures normally included in financial statements prepared in
accordance with generally accepted accounting principles have been condensed
or omitted pursuant to such rules and regulations, although the Company
believes that the disclosures made are adequate to make the information
presented not misleading. The condensed interim consolidated financial
statements should be read in conjunction with the financial statements and the
notes thereto, included in this Prospectus and the Company's Annual Report on
Form 10-K/A as filed with the Securities and Exchange Commission on April 1,
1996, for the year ended December 31, 1995.
 
  The accompanying condensed interim consolidated financial statements have
been prepared, in all material respects, in conformity with the standards of
accounting measurements set forth in Accounting Principles Board Opinion No.
28 and reflect, in the opinion of management, all adjustments, which are of a
normal recurring nature, necessary to summarize fairly the financial position
and results of operations for such periods. The results of operations for such
interim periods are not necessarily indicative of the results to be expected
for the full year.
 
  The Company considers all highly liquid investments with an original
maturity of three months or less to be cash and cash equivalents. As of March
31, 1996, the Company's cash and cash equivalents consisted of demand deposits
and money market accounts in banks and other financial institutions totaling
approximately $43.0 million and available-for-sale securities consisting of
commercial paper totaling approximately $2.4 million, which approximated
market value.
 
2. NET INCOME (LOSS) PER COMMON AND EQUIVALENT SHARE:
 
  Net income (loss) per common and equivalent share is based on the weighted
average number of shares outstanding during the periods presented. Pursuant to
the Securities and Exchange Commission Staff Accounting Bulletin No. 83, all
shares, options and warrants issued during the twelve months immediately
preceding the initial public offering were treated as if they had been
outstanding through March 31, 1995, using the treasury stock method and at a
per share price of $14.00, the initial public offering price.
 
  Fully-diluted net income (loss) per share is not presented as it would not
materially differ from primary net income (loss) per share.

4. MFS AND UUNET MERGER AGREEMENT:
 
  On April 30, 1996, UUNET and MFS Communications Company, Inc. ("MFS")
announced that the two companies had entered into an Agreement and Plan of
Merger (the "Merger Agreement"). Under the terms of the Merger Agreement, each
share of UUNET common stock would be converted into 1.777776 shares of MFS
common stock. Consummation of the merger is subject to, among other things,
approval by the stockholders of each company and clearance under the Hart-
Scott-Rodino Antitrust Improvements Act of 1976, as amended. Stockholders of
UUNET owning approximately 62 percent of the outstanding shares and
stockholders of MFS owning approximately 12 percent of the outstanding shares
have committed to vote in favor of the merger. The merger will be accounted
for by MFS as a purchase. See "Description of the Merger."
 
  MFS is a leading provider of telecommunications services to business and
government end users. The combined company would provide a single source for a
full range of Internet, voice, data and video services through an
international network platform.
 
5. ACQUISITION OF UNIPALM:
 
  On November 15, 1995, UUNET acquired Unipalm Group plc ("Unipalm"), a
provider of Internet access options, networking software, training and
consulting services in the United Kingdom and Europe. The acquisition was
accounted for as a pooling of interests and, as such, UUNET's financial
statements for the three months ended March 31, 1995 have been restated to
include the results of Unipalm. For the three month period ended March 31,
1995, UUNET had previously reported revenues of $6,482,000 as compared to
combined revenues of $15,020,000 and a net loss of $792,000 as compared to a
combined net loss of $263,000.
 
6. INVESTMENTS IN AFFILIATES:
 
  During the quarter ended March 31, 1996, UUNET acquired a 40% interest in
the outstanding capital stock of EUnet Deutschland GmbH ("EUnet Germany"), a
provider of Internet access options, applications and consulting services in
Germany, for $1.6 million. The investment in EUnet Germany is accounted for
under the equity method.
 
  On April 1, 1996, UUNET paid approximately $3.6 million in cash and issued
27,079 shares of its Common Stock with a then fair market value of
approximately $0.7 million to increase UUNET's equity ownership of UUNET
Canada, Inc. ("UUNET Canada"), from 20% to 51%. The financial statements of
UUNET Canada will be consolidated with UUNET's financial statements beginning
with the second quarter of 1996.

  The Company has been advised by the International Representatives that the
several International Underwriters initially propose to offer such Shares 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. The International Underwriters may allow, and such
dealers may re-allow, a concession not in excess of $     per Share to other
dealers. After the Offerings, the price to public and such concessions may be
changed.
 
  The Company has granted to the International Underwriters and the U.S.
Underwriters (the "U.S. Underwriters" and, collectively with the International
Underwriters, the "Underwriters") options, exercisable during the 30-day
period after the date of this Prospectus, to purchase up to 4,200,000
additional shares of MFS Common Stock from the Company at the price to public
less the underwriting discount, solely to cover over-allotments. To the extent
that the International Underwriters and the U.S. Underwriters exercise such
options, 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, Goldman, Sachs &
Co., Bear, Stearns & Co. Inc., Smith Barney Inc. and UBS Securities LLC are
acting as the representatives (the "U.S. Representatives"), providing for the
concurrent offer and sale of 22,400,000 Shares (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 are
purchased by the International Underwriters pursuant to the International
Underwriting Agreement, or by the U.S. Underwriters pursuant to the U.S.
Underwriting Agreement, all the Shares 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 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 5,600,000 Shares offered by the International Underwriters,
(i) it is not purchasing any shares of MFS 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 MFS Common Stock or
distribute this Prospectus to any person within 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 by the U.S.
Underwriters, (i) it is not purchasing any shares of MFS 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 MFS Common Stock or distribute any Prospectus relating to the
U.S. Offering to any person outside the United States or Canada or to anyone
other than a 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 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 International Underwriters and the
U.S. Underwriters of such number of shares of MFS Common Stock as may be
mutually agreed. The price of any shares of MFS 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 MFS 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.
 
  Each International Underwriter has severally represented and agreed that: (i)
it has not offered or sold and, prior to the date six months after the closing
date of the offering, will not offer to sell any shares of MFS Common Stock to
persons in the United Kingdom except to persons whose ordinary activities
involve them in acquiring, holding, managing or disposing of investments (as
principal or agent) for the purposes of their businesses or otherwise in
circumstances which have not resulted and will not result in an offer to the
public in the United Kingdom within the meaning of the Public Offers of
Securities Regulations 1995 (the "Regulations"); (ii) it has complied and will
comply with all applicable provisions of the Financial Services Act 1986 and
the Regulations with respect to anything done by it in relation to the MFS
Common Stock in, from or otherwise involving the United Kingdom; and (iii) it
has only issued or passed on or will only issue or pass on in the United
Kingdom any document received by it in connection with the issue of the MFS
Common Stock, to a person who is of a kind described in Article 11 (3) of the
Financial Services Act 1986 (Investment Advertisements) (Exemptions) Order
1995, or is a person to whom the document may otherwise lawfully be issued or
passed on.
 
  Purchasers of the shares of MFS Common Stock offered hereby may be required
to pay stamp taxes and other charges in accordance with the laws and practices
of the country of purchase in addition to the offering price set forth on the
cover page thereof.

indemnify the International Underwriters against certain liabilities and
expenses, including liabilities under the Securities Act, or contribute to
payments the International Underwriters may be required to make in respect
thereof.

  The Company has agreed not to offer, sell, contract to sell or otherwise
dispose of, directly or indirectly, or announce the offering of any shares of
MFS 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 MFS Common Stock, for 90 days from
the date of this Prospectus, without the prior written consent of the
International Representatives, except for (i) shares issued and sold in
connection with acquisitions by the Company, including the Merger, subject to
certain limitations, (ii) shares issued in connection with any employee
benefit or incentive plans of the Company, (iii) shares issued in respect of
obligations existing before the date of this Prospectus, (iv) shares issued in
connection with the Offerings made hereby and (v) a maximum of 1.5 million
options or 1.5 million outperformance options, with a three year vesting
schedule and a market exercise price to a financial advisor for financial
advisory services to be provided to the Company over the next three years.
    
  In connection with the Offerings, certain Underwriters and selling group
members who are qualifying registered market makers on the Nasdaq National
Market may engage in passive market making transactions in the MFS Common
Stock on the Nasdaq National Market in accordance with Rule 10b-6A under the
Exchange Act, during the two business day period before commencement of offers
or sales of the Shares offered hereby. Passive market making transactions must
comply with certain volume and price limitations and be identified as such. In
general, a passive market maker may display its bid at a price not in excess
of the highest independent bid for the security, and if all independent bids
are lowered below the passive market maker's bid, then such bid must be
lowered when certain purchase limits are exceeded.
 
  Goldman, Sachs & Co. ("Goldman Sachs") acted as financial advisor to UUNET
in connection with the Merger and rendered its opinion to the UUNET Board of
Directors regarding the fairness of the Merger consideration. UUNET agreed to
pay Goldman Sachs a success-based fee and to reimburse Goldman Sachs for its
out-of-pocket expenses in connection therewith, as well as agreeing to
indemnify Goldman Sachs against certain liabilities, including liabilities
under federal securities laws.
 
    CERTAIN UNITED STATES TAX CONSIDERATIONS FOR NON-UNITED STATES HOLDERS
 
  The following is a discussion of certain United States federal income and
estate tax consequences of the acquisition, ownership and disposition of
Shares applicable to Non-United States Holders of MFS Common Stock. In
general, a "Non-U.S. Holder" is any person other than (i) a citizen or
resident of the United States, (ii) a corporation or partnership created or
organized in the United States or under the laws of the United States or of
any State of (iii) an estate or trust whose income is includable in gross
income for United States federal income tax purposes regardless of its source.
The discussion is based on current law and is for general information only.
The discussion assumes that the MFS Common Stock will continue to be included
in the Nasdaq National Market. The discussion does not address aspects of
taxation other than federal income and estate taxation and does not address
all aspects of federal income and estate taxation. The discussion does not
consider any specific facts or circumstances that may apply to a particular
Non-U.S. Holder. Moreover, the discussion does not address legislation which
is currently being considered by Congress or has been proposed by the Treasury
Department that could adversely effect a Non-U.S. Holder. Accordingly,
prospective investors are urged to consult their tax advisors regarding the
United States federal, state, local, non-United States income and other tax
consequences of acquiring, holding and disposing of shares, and whether such a
prospective investor would be treated as a resident of the United States for
federal income tax purposes.
 
  Dividends. In general, dividends paid to a Non-U.S. Holder that are not
effectively connected with a trade or business carried on by the Non-U.S.
Holder within the United States will be subject to United States withholding
tax at a rate of 30% of the gross amount thereof. Dividends effectively
connected with a United States trade or business of a Non-U.S. Holder
generally will not be subject to
 
                                      97
<PAGE>
 
withholding (if the Non-U.S. Holder files certain forms with the payor of the
dividend) and generally will be subject to United States federal income tax at
the same rates and in the same manner as if the income had been received by a
domestic taxpayer. In the case of Non-U.S. Holder corporations, such
effectively connected income also may be subject to the branch profits tax
(which generally is imposed on a foreign corporation upon the repatriation from
the United States of effectively connected earnings and profits). Non-U.S.
Holders should consult any applicable income tax treaties, which may provide
for reduced withholding or other rules different from those described above. A
Non-U.S. Holder may be required to satisfy certain certification requirements
in order to claim treaty benefits or to otherwise claim a reduction of or
exemption from withholding under the foregoing rules.
 
  Sale of MFS Common Stock. Generally, a Non-U.S. Holder will not be subject to
United States federal income tax on any gain realized upon the disposition of
his MFS Common Stock unless (i) the Company is or has been during the five-year
period ending on the date of disposition, a "United States real property
holding corporation" for federal income tax purposes (which the Company has not
been, is not and is not likely to become) and the Non-U.S. Holder held,
directly or indirectly at anytime during the five-year period ending on the
date of disposition, more than 5% of the MFS Common Stock, (ii) the gain is
effectively connected with a trade or business carried on by the Non-U.S.
Holder within the United States or, if a tax treaty applies, is attributable to
a permanent establishment (generally an office or other fixed place of business
maintained by the Non-U.S. Holder in the United States), or (iii) the Non-U.S.
Holder is an individual who holds the MFS Common Stock as a capital asset and
is present in the United States for 183 days or more in the taxable year of the
disposition and either (a) such Non-U.S. Holder individual has a tax home as
specially defined for United States federal income tax purposes) in the United
States and either the gain from the disposition is not attributable to an
office or other fixed place of business maintained by the Non-U.S. Holder
individual in a foreign country or an income tax equal to 10% of the gain is
not actually paid to a foreign country or (b) the gain from the disposition is
attributable to an office or other fixed place of business maintained in the
United States by such Non-U.S. Holder individual. Gain that is effectively
connected with the conduct of a trade or business within the United States by a
Non-U.S. Holder will be subject to United States federal income tax on net
income that applies to United States persons (and, with respect to corporate
holders under certain circumstances, the branch profits tax) but will not be
subject to withholding. An individual described in (iii) above generally will
be subject to tax at a 30% rate on any gain recognized on such disposition.
Individual Non-U.S. Holders also may be subject to tax pursuant to provisions
of United States federal income tax law applicable to expatriates. Non-U.S.
Holders should consult applicable treaties, which may provide for different
rules.
 
  Estate Tax. MFS Common Stock, owned or treated as owned by an individual who
is not a citizen or resident (as specially defined for United States federal
estate tax purposes) of the United States at the time of death will be
includable in the individual's gross estate for United States federal estate
tax purposes, unless an applicable tax treaty provides otherwise. Such
individual's estate may be subject to United States federal estate tax on the
property includable in the estate for United States federal estate tax
purposes. Estates of nonresident aliens are generally allowed a credit that is
equivalent to an exclusion of $60,000 of assets from the estate for United
States federal estate tax purposes; however, applicable tax treaties may
provide for an increased estate tax credit.
 
  Backup Withholding and Information Reporting. The Company must report
annually to the Internal Revenue Service (the "IRS") and to each Non-U.S.
Holder the amount of dividends paid to, and the tax withheld with respect to,
each Non-U.S. Holder. These information reporting requirements apply regardless
of whether withholding was reduced or eliminated by an applicable tax treaty.
Copies of these information returns also may be made available under the
provisions of a specific treaty or agreement to the tax authorities in the
country in which the Non-U.S. Holder resides. United States information
reporting and backup withholding tax (which generally is a withholding tax
imposed at the rate of 31% on certain payments to United States persons that
fail to furnish the information required
 
                                       98
<PAGE>
 
under the United States information reporting requirements) generally will not
apply to dividends paid on MFS Common Stock to a Non-U.S. Holder either at an
address outside the United States (provided that the payor does not have
definite knowledge that the payee is a United States person) or if the
dividends are subject to withholding at the 30% rate (or lower treaty rate).
 
  The payment of the proceeds from the disposition of MFS Common Stock to or
through the United States office of a broker will be subject to information
reporting and backup withholding unless the owner, under penalties of perjury,
certifies, among other things, as to its status as a Non-U.S. Holder or
otherwise establishes an exemption (and the broker has no actual knowledge to
the contrary). The payment of the proceeds from the disposition of MFS Common
Stock to or through a non-United States office of a broker generally will not
be subject to information reporting or backup withholding. However, information
reporting (but not backup withholding) will apply to a payment of the proceeds
from a sale of MFS Common Stock if the payment is made through a non-United
States office of a United States broker or through a non-United States office
of a non-United States broker that is (i) a controlled foreign corporation as
to the United States or (ii) a person 50% or more of whose gross income for a
certain three-year period is effectively connected with a United States trade
or business, unless the broker has documentary evidence in its records that the
holder is a Non-U.S. Holder and certain conditions are met, or the holder
otherwise establishes an exemption.
 
  Backup withholding tax is not an additional tax and may be credited against a
holder's United States federal income tax liability, provided that required
information is furnished to the IRS. Non-U.S. Holders generally may obtain a
refund of any excess amount withheld under the backup withholding rules by
filing the appropriate refund claim with the IRS.
 
  The Treasury Department has issued proposed regulations that would modify the
information and backup withholding rules as they apply to Non-U.S. Holders. The
proposed regulations would unify the current certification procedures and forms
and would, in certain circumstances, require additional information from Non-
U.S. Holders claiming treaty benefits. The proposed regulations are scheduled
to take effect January 1, 1997, and are subject to further changes.

                                    GLOSSARY
 
  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 LANs, to deliver traffic at varying rates, permitting a mix
of data, voice and video.
 
  Backbone--A centralized high-speed network that interconnects smaller,
independent networks.
 
  Bandwidth--The number of bits of information which can move through a
communications medium in a given amount of time.
 
  CAP (competitive access provider)--A company that provides its customers with
an alternative to the LEC for local transport of private line and special
access telecommunications services.
 
  Central offices--The switching centers or central switching facilities of the
LECs.
 
  Co-carrier status--A regulatory scheme under which the incumbent LEC is
required to integrate new, competing providers of local exchange service, such
as the Company, into the systems of traffic exchange, inter-carrier
compensation, and other inter-carrier relationships that already exist among
LECs in most jurisdictions.
 
  Collocation--The ability of a CAP such as the Company to connect its network
to the LECs central offices. Physical collocation occurs when a CAP places its
network connection equipment inside the LEC's central offices. Virtual
collocation is an alternative to physical collocation pursuant to which the LEC
permits a CAP to connect its network to the LEC's central offices on comparable
terms, even though the CAP's network connection equipment is not physically
located inside the central offices.
 
  DS-1--A data communications circuit capable of transmitting data at 1.5 Mbps
(sometimes called T-1).
 
  DS-3--A data communications circuit capable of transmitting data at 45 Mbps
(sometimes called T-3).
 
  Dedicated--Telecommunications lines dedicated or reserved for use by
particular customers.
 
  Digital--A method of storing, processing and transmitting information through
the use of distinct electronic or optical pulses that represent the binary
digits 0 and 1. Digital transmission and switching technologies employ a
sequence of these pulses to represent information as opposed to the
continuously variable analog signal. The precise digital numbers minimize
distortion (such as graininess or snow in the case of video transmission, or
static or other background distortion in the case of audio transmission).
 
  E-3--A data communications circuit capable of transmitting data at 34 Mbps
(typically used outside North America).
 
  Ethernet--A local area network technology used for connecting computers,
printers, workstations, terminals, etc., within the same building. Ethernet
operates over twisted wire or coaxial cable at speeds up to 10 megabits per
second. Ethernet is the most popular LAN technology.
 
  FCC--Federal Communications Commission.
 
  FDDI (Fiber Distributed Data Interface)--Based on fiber optics, FDDI is a 100
megabit per second local area network technology used to connect computers,
printers, and workstations at very high speeds. FDDI is also used as backbone
technology to interconnect other LANs.
 
 
                                      101
<PAGE>
 
  Fiber mile--The number of route miles installed (excluding pending
installations) along a telecommunications path multiplied by the number of
fibers along that path. See the definition of "route mile" below.
 
  Firewall--A system placed between networks that filters data passing through
it and removes unauthorized traffic, thereby enhancing the security of the
network.
 
  Frame relay--An information transfer standard for relaying traffic based on
an address contained in the six byte header of a variable length packet that is
up to 2,106 bytes long. Frame relay has less overhead than ATM but may be
difficult to implement at speeds greater than 45 Mps.
 
  Graphical user interface--A means of communicating with a computer by
manipulating icons, menus and windows rather than using text commands.
 
  Home page--An entry point for a collection of information presented through
the World Wide Web.
 
  Interconnection Decisions--Rulings by the FCC announced in September 1992 and
August 1993, which require the BOCs and most other large LECs to provide
interconnection in LEC central offices to any CAP, long distance carrier or end
user seeking such interconnection for the provision of interstate special
access and switched access transport services.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  Section 145 of the Delaware General Corporation Law (the "DGCL") empowers a
Delaware corporation to 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 such corporation) by reason of the
fact that such person is or was a director, officer, employee or agent of such
corporation, or is or was serving at the request of such corporation as a
director, officer, employee or agent of another corporation or enterprise. A
corporation may, in advance of the final disposition of any civil, criminal,
administrative or investigative action, suit or proceeding, pay the expenses
(including attorneys' fees) incurred by any officer, director, employee or
agent in defending such action, provided that the director or officer
undertake to repay such amount if it shall ultimately be determined that he or
she is not entitled to be indemnified by the corporation. A corporation may
indemnify such person against expenses (including attorneys' fees), judgments,
fines and amounts paid in settlement actually and reasonably incurred by such
person in connection with such action, suit or proceeding if he or she 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 reasonable cause to believe his or her conduct
was unlawful.
 
  A Delaware corporation may indemnify officers and directors in an action by
or in the right of the corporation to procure a judgment in its favor under
the same conditions, except that no indemnification is permitted without
judicial approval if the officer or director is adjudged to be liable to the
corporation. Where an officer or director is successful on the merits or
otherwise in the defense of any action referred to above, the corporation must
indemnify him or her against the expenses (including attorneys' fees) which he
or she actually and reasonably incurred in connection therewith. The
indemnification provided is not deemed to be exclusive of any other rights to
which an officer or director may be entitled under any corporation's by-law,
agreement, vote or otherwise.
 
                                     II-1

  In accordance with Section 145 of the DGCL, Article 7 of MFS' Restated
Certificate of Incorporation (the "Restated Certificate") and MFS' By-Laws
(the "By-Laws") provide that MFS shall indemnify each person who is or was a
director, officer or employee of MFS (including the heirs, executors,
administrators or estate of such person) or is or was serving at the request
of MFS as director, officer or employee of another corporation, partnership,
joint venture, trust or other enterprise, to the fullest extent permitted
under subsections 145(a), (b), and (c) of the DGCL or any successor statute.
The indemnification provided by the Restated Certificate and the By-Laws shall
not be deemed exclusive of any other rights to which any of those seeking
indemnification or advancement of expenses may be entitled under any by-law,
agreement, vote of stockholders or disinterested directors or otherwise, both
as to action in his or her official capacity and as to action in another
capacity while holding such office, and shall continue as to a person who has
ceased to be a director, officer, employee or agent and shall inure to the
benefit of the heirs, executors and administrators of such a person. Expenses
(including attorneys' fees) incurred in defending a civil, criminal,
administrative or investigative action, suit or proceeding upon receipt of an
undertaking by or on behalf of the indemnified person to repay such amount if
it shall ultimately be determined that he is not entitled to be indemnified by
MFS. Article 8 of the Restated Certificate provides that a director of MFS
shall not be personally liable to MFS or its stockholders for monetary damages
for breach of fiduciary duty as a director, except for liability (i) for any
breach of the director's duty of loyalty to MFS or its stockholders, (ii) for
acts or omissions not in good faith or which involve intentional misconduct or
a knowing violation of law, (iii) under Section 174 of the DGCL, or (iv) for
any transaction from which the director derived an improper personal benefit.
If the DGCL is amended to authorize corporate action further eliminating or
limiting the personal liability of directors, then the liability of a director
of MFS shall be eliminated or limited to the fullest extent permitted by the
DGCL as so amended.
 
  Section 8.7 of the By-Laws provides that MFS may purchase and maintain
insurance on behalf of its directors, officers, employees and agents against
any liabilities asserted against such persons arising out of such capacities.

ITEM 17. UNDERTAKINGS.
 
  The undersigned Registrant hereby undertakes that, for the purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934 that is incorporated by reference in this
registration statement shall be deemed to be a new registration statement
relating to the Securities offered herein, and the offering of such Securities
at that time shall be deemed to be the initial bona fide offering thereof.
 
  Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the provisions described under Item 15 of this
registration statement, or otherwise (other than insurance), the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in such Act and is,
therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the
Registrant in the successful defense of any action, suit or proceeding) is
asserted by such director, officer or controlling person, in connection with
the Securities being registered, the Registrant will, unless in the opinion of
its counsel the matter has been settled by controlling precedent, submit to a
court of appropriate jurisdiction the question whether such indemnification by
it is against public policy as expressed in such Act and will be governed by
the final adjudication of such issue.
 
  The undersigned registrant herby undertakes that:
 
    (1) For purposes of determining any liability under the Securities Act of
  1933, the information omitted from the form of prospectus filed as part of
  this registration statement in reliance upon Rule 430A and contained in 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.

Ladies and Gentlemen:

We have acted as counsel to MFS Communications Company, Inc. (the "Company"), a
corporation organized under the laws of the State of Delaware, in connection
with the preparation of a registration statement on Form S-3 (as amended, the
"Registration Statement") relating to an offering by the Company of up to
32,200,000 shares of common stock, par value $.01 per share, of the Company (the
"Common Stock").

We have examined copies of the certificate of incorporation and by-laws of the
Company, and the amendments thereto, the Registration Statement, certain
resolutions adopted by the Company's Board of Directors and other records and
documents that we have deemed necessary for the purpose of this opinion.  We
have also examined such other documents, papers, statutes and authorities as we
have deemed necessary to form a basis for the opinion hereinafter expressed.  In
our examination, we have assumed the genuineness of all signatures and the
conformity to original documents of all copies submitted to us.  As to various
questions of fact material to our opinion, we have relied on statements and
certificates of officers and representatives of the Company and public
officials.

Based on the foregoing, we are of the opinion that the Common Stock, when duly
sold, issued and paid for in accordance with the terms described in the
Registration Statement, will be duly authorized and validly issued, and that
such Common Stock will be fully paid and nonassessable.

We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to us in the Prospectus included as
part of the Registration Statement.

Very truly yours,

/s/ Willkie Farr & Gallagher
