                                    Level 3
 
   We engage in the information services, communications and coal mining
businesses through ownership of operating subsidiaries and substantial equity
positions in public companies. In late 1997, we announced a business plan to
increase substantially our information services business and to expand the
range of services we offer. This plan is referred to in this prospectus
supplement as the "Business Plan." We are implementing the Business Plan by
building an international, facilities-based communications network based on
Internet Protocol, or IP, technology.
 
   When complete, our network will combine both local and long distance
networks and connect customers end-to-end across the U.S. and in Europe and the
Pacific Rim. Over the next three to five years, our network is expected to
encompass:
 
  . an intercity network covering nearly 16,000 miles in North America;
 
  . backbone facilities in 40 North American markets;
 
  . leased backbone facilities in 10 additional North American markets;
 
  . an intercity network covering approximately 3,500 miles across Europe;
 
  . leased or owned backbone facilities in 13 European and 8 Pacific Rim
    markets; and
 
  . transoceanic capacity.
 
   We expect to complete the U.S. intercity portion of the network during the
first quarter of 2001. In the interim, we have leased a national network over
which we began to offer services in the third quarter of 1998.
 
   We have rights-of-way along approximately 14,400 miles of our planned U.S.
network route, have completed construction of 410 route miles of our intercity
network and have an additional 850 route miles under construction. We have
entered into transoceanic capacity agreements for three systems. We have local
network development underway in 25 U.S. cities with fiber loops operational in
three cities. We have secured approximately 1.25 million square feet of space
for our gateway facilities which vary in size and the nature of services
currently offered. Our gateway facilities are operational in 17 U.S. cities and
in London and Frankfurt.
 
   We believe that, as technology advances, a comprehensive range of both
consumer and business communications services will be provided over networks,
such as ours, utilizing IP technology. These services
 
                                      S-4
<PAGE>
 
will include traditional voice services and fax transmission, as well as other
data services such as Internet access. We believe this shift has begun, and
over time should accelerate, since IP networks offer:
 
  .  more efficient use of network capacity than the traditional public
     switched telephone networks;
 
  .  an open protocol which allows for market driven development of new uses
     and applications;
 
  .  the prospect of technological advances that will address problems
     currently associated with IP-based applications; and
 
  .  a standardized web browser interface for data and applications that
     makes it easier for end users to access and use these resources.
 
Level 3's Strategy
 
   Key elements of our strategy include:
 
  .  Become the Low Cost Provider of Communications Services. We are
     designing our network to provide high quality communications services at
     a lower cost and to incorporate more readily future technological
     improvements relative to older, less adaptable networks.
 
  .  Offer a Comprehensive Range of Communications Services. As the Business
     Plan is implemented, we intend to provide a comprehensive range of
     communications services over our network, including private line,
     colocation, Internet access, managed modem and voice and fax
     transmission services.
 
  .  Provide Seamless Interconnection to the Public Switched Telephone
     Network. We and other technology providers are developing technology to
     allow seamless interconnection of IP networks with the public switched
     telephone network. A seamless interconnection will allow customers to
     use our IP-based services, including voice and fax, without modifying
     existing telephone and fax equipment or existing dialing procedures
     (that is, without the need to dial access codes or follow other similar
     special procedures).
 
  .  Accelerate Market Roll-out. To support the launch of our services and
     develop a customer base in advance of completing our network build, we
     have begun offering services in 17 U.S. cities and in London and
     Frankfurt over leased local and intercity facilities. Over time, these
     leased networks will be displaced by networks that we are constructing.
 
  .  Expand Target Market Opportunities. To increase revenue-producing
     traffic on our network more rapidly, we are using both a direct sales
     force and alternative distribution channels. These channels allow us to
     gain access to a substantially larger base of potential customers than
     we could otherwise initially address solely through a direct sales
     force.
 
  .  Develop Advanced Business Support Systems. We are developing a
     substantial, scalable and web-enabled business support system
     infrastructure specifically designed to enable us to offer services
     efficiently to targeted customers. We believe that this system will
     reduce our operating costs, give our customers direct control over some
     of the services they buy from us and allow us to grow rapidly without
     redesigning the architecture of the business support system.
 
  .  Leverage Existing Information Services Capabilities. We are expanding
     our existing capabilities in computer network systems integration,
     consulting, outsourcing and software reengineering, with particular
     emphasis on the conversion of legacy software systems to systems that
     are compatible with IP networks and web browser access.
 
  .  Attract and Motivate High Quality Employees. We have developed programs
     designed to attract and retain employees with the technical skills
     necessary to implement the Business Plan. The programs include our
     Shareworks stock purchase plan and our Outperform Stock Option program.

Competitive Advantages
 
   We believe that we have the following competitive advantages that, together
with our strategy, will assist us in implementing the Business Plan:
 
  .  Experienced Management Team. We have assembled a management team that we
     believe is well suited to implement the Business Plan. Most of our
     senior management has been involved in leading the development and
     marketing of telecommunications products and in designing, constructing
     and managing intercity, metropolitan and international networks.
 
  .  Opportunity to Create a More Readily Upgradable Network
     Infrastructure. Our network design strategy seeks to take advantage of
     recent innovations, incorporating many features that are not present in
     older communications networks and provide us flexibility to take
     advantage of future developments and innovations.
 
  .  Integrated End-to-End Network Platform. We believe that the integration
     of our local and intercity networks will expand the scope and reach of
     our on-net customer coverage and facilitate the uniform deployment of
     technological innovations as we manage our future upgrade paths.
 
  .  Systems Integration Capabilities. We believe that our ability to offer
     computer outsourcing and systems integration services, particularly
     services relating to allowing a customer's legacy systems to be accessed
     with web browsers, will provide additional opportunities for selling our
     products and services.
 
   Our principal executive offices are located at 3555 Farnam Street, Omaha,
Nebraska 68131 and our telephone number is (402) 536-3677. We are constructing
a new headquarters outside of Denver, Colorado, which we expect to begin
occupying during the summer of 1999.

                       Summary Financial Data of Level 3
 
   The summary financial data presented below as of and for the fiscal years
ended the last Saturday in December of 1994, 1995, 1996 and 1997 have been
derived from Level 3's audited consolidated financial statements and the notes
related to those financial statements. The selected financial data presented
below as of and for the fiscal year ended December 31, 1998 have been derived
from Level 3's unaudited financial statements. In the opinion of management,
the unaudited financial statements have been prepared on the same basis as the
audited financial statements and include all adjustments, consisting of normal
recurring adjustments, necessary for a fair presentation of the financial
position and results of operations as of such dates and for such periods. The
following information should be read in conjunction with Level 3's audited
consolidated financial statements and the notes related to those financial
statements, which are included in this prospectus supplement. Since the
Business Plan represents a significant expansion of Level 3's communications
and information services business, Level 3 does not believe that the following
information serves as a meaningful indicator of Level 3's future financial
condition or results of operations. Level 3 expects to incur substantial net
operating losses for the foreseeable future, and there can be no assurance that
Level 3 will be able to achieve or sustain operating profitability in the
future.

(1)  In October 1993, Level 3 acquired 35% of the outstanding shares of C-TEC
     Corporation, which shares entitled Level 3 to 57% of the available voting
     rights of C-TEC Corporation. At December 28, 1996, Level 3 owned 48% of
     the outstanding shares and 62% of the voting rights of C-TEC Corporation.
 
     As a result of the restructuring of C-TEC Corporation in 1997, Level 3 owns
     less than 50% of the outstanding shares and voting rights of each of the
     three entities into which C-TEC Corporation was divided, and therefore
     accounted for each entity using the equity method in 1997 and 1998. Level 3
     consolidated C-TEC Corporation in its financial statements from 1994 to
     1996.
 
     The financial position and results of operations of the construction and
     mining management businesses of Level 3 have been classified as
     discontinued operations due to the March 31, 1998 split-off of Level 3's
     construction and mining management businesses from its other businesses.
     Level 3's construction and mining management businesses are referred to in
     this prospectus supplement as the "Construction Group."
 
     In 1995, Level 3 dividended its investment in its former subsidiary, MFS
     Communications Company, Inc. to the holders of the Class D Stock. MFS
     Communications Company, Inc. is sometimes referred to in this prospectus
     supplement as "MFS." MFS' results of operations have been classified as a
     single line item on the statements of earnings for 1994 and 1995. MFS was
     consolidated in the 1994 balance sheet of Level 3. In 1994, MFS received
     net proceeds of approximately $500 million from the sale of 9.375% Senior
     Discount Notes.

     Level 3 sold its energy segment to CalEnergy Company, Inc. in 1998 and
     classified it as discontinued operations within the financial statements.
 
(2)  Level 3 incurred significant expenses in conjunction with the expansion of
     its communications and information services businesses in 1998.
 
     In 1998, Level 3 acquired XCOM Technologies, Inc. and its developing
     telephone-to-IP network bridge technology. Level 3 recorded a $115 million
     nondeductible charge against earnings for the write-off of in-process
     research and development acquired in the transaction.
 
(3)  In 1998, Level 3 recognized a gain of $608 million equal to the difference
     between the carrying value of the Construction Group and its fair value.
     No taxes were provided on this gain due to the tax-free nature of the
     split-off.
 
     In 1998, Cable Michigan, Inc. was acquired by Avalon Cable of Michigan,
     Inc. Level 3 received approximately $129 million for its shares of Cable
     Michigan, Inc. in the acquisition and recognized a pre-tax gain of
     approximately $90 million in the fourth quarter of 1998.
 
     Level 3 also recognized in 1998 an after-tax gain of $324 million on the
     sale of its energy segment to CalEnergy Company, Inc.
 
(4)  In 1998, Level 3 issued $2 billion of 9.125% Senior Notes due 2008 and
     $833 million principal amount at maturity of 10.5% Senior Discount Notes
     due 2008.

                                  RISK FACTORS
 
   Before you invest in shares of our common stock, you should carefully
consider the following risks.
 
We are dependent on our new Business Plan that relies on Internet Protocol
technology
 
   The current status of our Business Plan makes evaluation of its risks and
rewards extremely difficult and speculative. The Business Plan depends upon a
shift in providing communications services over Internet Protocol-based
networks instead of the traditional public-switched networks. Our strategy
assumes that we and others will develop technology that solves the problems
currently associated with Internet Protocol-based applications, and that others
will continue to develop new uses and applications for Internet Protocol-based
networks. The success of our Business Plan depends on other assumptions as
well, such as our ability to use open, non-proprietary interfaces in our
network software and hardware that allow us to buy equipment in the future from
multiple vendors. Finally, we must generate substantial traffic volume at
acceptable prices on our network in order to realize the anticipated operating
efficiencies and cost benefits of the network.
 
Substantial operating losses are expected for the foreseeable future
 
   The development of our Business Plan requires significant capital
expenditures. We expect to incur a large portion of these capital expenditures
before we receive any significant related revenues from our Business Plan.
Because of these capital expenditures and the related early operating expenses,
we expect substantial negative operating cash flow and net losses for the
foreseeable future. For 1998, we incurred a loss from continuing operations of
$202 million. We expect our operating losses for the foreseeable future to be
substantially higher. We may never establish a significant customer base for
our communications and information services business, and even if we do, we may
continue to sustain substantial negative operating cash flow and net losses as
a result of low prices or higher costs.
 
   Since our new Business Plan is a significant expansion of our communications
and information services business, we believe that our historical financial
results for periods ending prior to January 1, 1998 will not provide investors
with a meaningful indicator of our future financial condition or results of
operations.
 
A failure to finance our substantial capital requirements could adversely
affect our Business Plan
 
   The implementation of our Business Plan and our ability to meet our
projected growth depends on our ability to secure substantial additional
financing. We estimate that the implementation of our Business Plan, as
currently contemplated, requires between $8 and $10 billion over the 10-year
period of the plan. However, the amount of additional financing we need could
be higher than we currently estimate. The implementation of our Business Plan
and our future financial results could be adversely affected if we are
unsuccessful in obtaining required financing through:
 
  .  raising debt or equity capital at the times we need on terms that we
     consider acceptable;
 
  .  generating cash flow from our operations; and
 
  .  offering others fiber optic capacity on our network or access to our
     conduits.
 
   If we fail to obtain the required financing, we may be required to delay or
abandon some of our future expansion or spending plans. Our existing level of
debt and its terms may limit our ability to raise additional capital and
otherwise restrict our activities. In addition, if our operations do not
produce positive cash flow in sufficient amounts to pay our financing
obligations, our future financial results and our ability to implement our
Business Plan will be materially and adversely affected.
 
 
                                      S-9
<PAGE>
 
Difficulties in constructing our network could increase its estimated costs and
delay its scheduled completion
 
   The construction, operation and any upgrading of our network is a
significant undertaking. Administrative, technical, operational and other
problems that could arise may be more difficult to address and solve due to the
significant size and complexity of the planned network. We are also dependent
on timely performance by third-party suppliers and contractors. In addition,
important aspects of our network, such as voice and fax capability, will rely
on technology that is in the development stage or that is largely commercially
unproven. This new technology also may not be compatible with existing
technology. Many of these factors and problems are beyond our control. As a
result, the entire network may not be completed as planned for the costs and in
the time frame that we currently estimate. We may be materially adversely
affected as a result of any significant increase in the estimated cost of the
network or any significant delay in its anticipated completion.
 
   After its initial completion, future expansions and adaptations of our
network's electronic and software components may be necessary in order to
respond to:
 
  .  a growing number of customers;
 
  .  increased demands by our customers to transmit larger amounts of data;
 
  .  changes in our customers' service requirements; and
 
  .  technological advances by our competitors.
 
   Any expansion or adaptation of our network will require substantial
additional financial, operational and managerial resources. If we are unable to
expand or adapt our network to respond to these developments on a timely basis
and at a commercially reasonable cost, then our business will be materially
adversely affected.
 
A failure to develop or acquire satisfactory voice or fax technology for
Internet Protocol networks could adversely affect our business
 
   We are in the process of developing technology that we believe will avoid
the need for customers on an Internet Protocol-based network to dial access
codes or follow other special procedures to initiate a voice or fax call. We do
not believe that this technology is currently commercially available. Our
efforts to develop or acquire this technology in a timely manner and at an
acceptable cost may not be successful. Our failure to develop or acquire this
technology in a timely and cost efficient manner could have a material adverse
effect on us. To date, Internet Protocol voice telephony has also had
significant problems with quality, latency, reliability and security. Until we
begin commercially deploying our voice or fax telephony services, we cannot
predict whether our plans for solving these problems will work.
 
Our Business Plan requires the development of effective business support
systems to implement customer orders and to provide and bill for services
 
   Our Business Plan depends on our ability to develop sophisticated business
support systems. This is a complicated undertaking requiring significant
resources and expertise and support from third-party vendors. Business support
systems are needed for:
 
  .  implementing customer orders for services;
 
  .  provisioning, installing and delivering these services; and
 
  .  monthly billing for these services.
 
   Since our Business Plan provides for rapid growth in the number and volume
of products and services we offer, we need to develop these business support
systems on a schedule sufficient to meet our proposed service rollout dates. In
addition, we will require these business support systems to expand and adapt
with our rapid growth. The failure to develop effective business support
systems could have a material adverse effect on our ability to implement our
Business Plan.
 
                                      S-10
<PAGE>
 
We may be unable to hire and retain sufficient qualified personnel; the loss of
any of our key executive officers could adversely affect us
 
   We believe that our future success will depend in large part on our ability
to attract and retain highly skilled, knowledgeable, sophisticated and
qualified managerial, professional and technical personnel. To
implement our Business Plan, we need to have a substantial number of additional
employees. We have experienced significant competition in attracting and
retaining personnel who possess the skills that we are seeking. As a result of
this significant competition, we may experience a shortage of qualified
personnel. Our businesses are managed by a small number of key executive
officers, particularly James Q. Crowe, Chief Executive Officer, R. Douglas
Bradbury, Chief Financial Officer, and Kevin J. O'Hara, Chief Operating
Officer. The loss of any of these key executive officers could have a material
adverse effect on us.
 
Inability to manage effectively our planned rapid expansion could adversely
affect our operations
 
   Our Business Plan contemplates rapid expansion of our business for the
foreseeable future. This growth will increase our operating complexity and
require that we, among other things, rapidly:
 
  .  expand our employee base with highly skilled personnel;
 
  .  develop, introduce and market new products and services;
 
  .  integrate any acquired operations and joint ventures;
 
  .  develop financial and management controls and systems; and
 
  .  control expenses related to our Business Plan.
 
   The significant size and complexity of our planned network and planned rate
of expansion will make it more difficult to satisfy these requirements. Our
failure to satisfy any of these requirements, or otherwise manage our growth
effectively, could have a material adverse effect on us.
 
   If we were to make strategic investments, acquisitions or joint ventures,
our resources and management time could be diverted and we may be unable to
integrate them successfully with our existing network and services.
 
Burdensome peering and transit arrangements result in higher costs
 
   Currently, due to the absence of peering agreements with two of the largest
Internet access providers, Level 3 is required to make transit payments with
respect to most of its Internet traffic. Peering agreements with Internet
service providers allow us to access the Internet and exchange transit for free
with these providers. Recently, many Internet service providers that previously
offered peering have reduced or eliminated peering relationships or are
establishing new, more restrictive criteria for peering. If we cannot enter
into peering agreements on satisfactory terms and therefore must continue to
make transit payments, the costs could have a material adverse effect on our
margins for our products that require Internet access.
 
We must obtain and maintain permits and rights-of-way to develop our network
 
   To acquire and develop our network, we must obtain many local franchises and
other permits. We also must obtain rights to use underground conduit and aerial
pole space and other rights-of-way and fiber capacity. The process of obtaining
these franchises, permits and rights is time consuming and burdensome. If we
are unable, on acceptable terms and on a timely basis, to obtain and maintain
the franchises, permits and rights needed to implement our Business Plan, the
buildout of our network could be materially adversely affected. In addition,
the cancellation or non-renewal of the franchises, permits or rights we do
obtain could materially adversely affect us.
 
 
                                      S-11
<PAGE>
 
Termination of relationships with key suppliers could cause delay and costs
 
   Until we complete the company-owned portion of our network, we will lease
substantially all of our intercity communications capacity in North America,
Europe and possibly elsewhere. As a result, we will be dependent on the
providers of this capacity. In addition, we intend to lease a significant
amount of capacity from local exchange carriers to connect our customers to our
gateway sites. We are also dependent on third-party suppliers for substantial
amounts of fiber, conduit, computers, software, switches/routers and related
components that we will assemble and integrate into our network. If any of
these relationships is terminated or a supplier fails to provide reliable
services or equipment and we are unable to reach suitable alternative
arrangements quickly, we may experience significant delays and additional
costs. If that happens, we could be materially adversely affected.
 
Our industry is highly competitive with participants that have greater
resources and existing customers
 
   Our industry, the communications and information services industry, is
highly competitive. Many of our existing and potential competitors have
financial, personnel, marketing and other resources significantly greater than
ours. Many of these competitors have the added competitive advantage of an
existing customer base. Significant new competitors could arise as a result of:
 
  .  increased consolidation and strategic alliances in the industry
     resulting from recent Congressional and FCC actions;
 
   .  allowing foreign carriers to compete in the U.S. market;
 
   .  further technological advances; and
 
   .  further deregulation and other regulatory initiatives.
 
   If we are unable to compete successfully, our business could be materially
adversely affected.
 
Rapid technological changes can lead to further competition
 
   The communications and information services industry is subject to rapid and
significant changes in technology. In addition, the introduction of new
products or technologies may reduce the cost or increase the supply of certain
services similar to those that we plan to provide. As a result, our most
significant competitors in the future may be new entrants to the communications
and information services industry. These new entrants may not be burdened by an
installed base of outdated equipment. Technological changes and the resulting
competition on our operations could have a material adverse effect on us.
 
Increased industry capacity and other factors could lead to lower prices for
our products and services
 
   There are currently three U.S. long distance fiber optic networks that are
owned by each of AT&T, MCI WorldCom and Sprint, as well as numerous local
networks. Others, including Qwest Communications International Inc., IXC
Communications, Inc. and The Williams Companies, Inc., are deploying additional
networks that use advanced technology similar to that of our network. These
networks offer significantly more capacity than is currently available in the
marketplace. This additional capacity may cause significant decreases in the
prices for services. Prices may also decline due to capacity increases
resulting from technological advances and strategic alliances, such as long
distance capacity purchasing alliances among regional Bell operating companies.
These price declines may be particularly severe if recent trends causing
increased demand for capacity, such as Internet usage, change. Rapid growth in
the use of the Internet is a recent phenomenon, and may not continue at the
same rate.
 
We are subject to significant regulation that could change in an adverse manner
 
   Communications services are subject to significant regulation at the
federal, state, local and international levels. These regulations affect us and
our existing and potential competitors. Delays in receiving required
 
                                      S-12
<PAGE>
 
regulatory approvals, completing interconnection agreements with incumbent
local exchange carriers or the enactment of new and adverse regulations or
regulatory requirements may have a material adverse effect on us. In addition,
future legislative, judicial, and regulatory agency actions could have a
material adverse effect on us.
 
   Recent federal legislation provides for a significant deregulation of the
U.S. telecommunications industry, including the local exchange, long distance
and cable television industries. This legislation remains subject to
judicial review and additional FCC rulemaking. As a result, we can not predict
the legislation's effect on our future operations. Many regulatory actions are
under way or are being contemplated by federal and state authorities regarding
important items. These actions could have a material adverse effect on us.
 
Canadian law currently does not permit us to offer services in Canada
 
   Ownership of facilities that originate or terminate traffic in Canada is
currently limited to Canadian carriers. This restriction will block our entry
into the Canadian market unless appropriate arrangements can be made to address
it.
 
Potential regulation of internet service providers could adversely affect our
operations
 
   The FCC has to date treated Internet service providers as enhanced service
providers. Enhanced service providers are currently exempt from federal and
state regulations governing common carriers, including the obligation to pay
access charges and contribute to the universal service fund. The FCC is
currently examining the status of Internet service providers and the services
they provide. If the FCC were to determine that Internet service providers, or
the services they provide, are subject to FCC regulation, including the payment
of access charges and contribution to the universal service funds, it could
have a material adverse effect on us.
 
   The FCC has also been considering whether local carriers are obligated to
pay compensation to each other for the transport and termination of calls to
Internet service providers when a local call is placed from an end user of one
carrier to an Internet service provider served by the competing local exchange
carrier. If the FCC were to determine that reciprocal compensation does not
apply and carriers may be unable to recover their costs or will be compensated
at a significantly lower rate, it could have a material adverse effect on us.
 
Network failure or delays and errors in transmissions expose us to potential
liability
 
   Our network will use a collection of communications equipment, software,
operating protocols and proprietary applications for the high speed
transportation of large quantities of data among multiple locations. Given the
complexity of our proposed network, it may be possible that data will be lost
or distorted. Delays in data delivery may cause significant losses to a
customer using our network. Our network may also contain undetected design
faults and software bugs that, despite our testing, may be discovered only
after the network has been installed and is in use. The failure of any
equipment or facility on the network could result in the interruption of
customer service until we effect necessary repairs or install replacement
equipment. Network failures, delays and errors could also result from natural
disasters, power losses, security breaches and computer viruses. These
failures, faults or errors could cause delays, service interruptions, expose us
to customer liability or require expensive modifications that could have a
material adverse effect on our business.
 
Intellectual property and proprietary rights of others could prevent us from
using necessary technology to provide Internet Protocol voice services
 
   While we do not know of any technologies that are patented by others that we
believe are necessary for us to provide Internet Protocol voice services, this
necessary technology may in fact be patented by other parties either now or in
the future. If this technology were held under patent by another person, we
would have to negotiate a license for the use of that technology. We may not be
able to negotiate such a license at a price that
 
                                      S-13
<PAGE>
 
is acceptable to us. The existence of such a patent, or our inability to
negotiate a license for any such technology on acceptable terms, could force us
to cease using the technology and offering products and services incorporating
the technology.
 
Our Year 2000 compliance efforts may not succeed, and PKS Systems may have
liability from its Year 2000 customer projects
 
   We are conducting a review of our computer systems, including the computer
systems used in our computer outsourcing business, to identify systems that
could be affected by the Year 2000 computer issue. We are also developing and
implementing a plan to resolve the issue. If any required plan to resolve the
Year 2000 problem is unsuccessful, however, that result could have a material
adverse effect on us. Until our review is completed and our plans are developed
and completed, we cannot predict with certainty whether the cost of resolving
the Year 2000 issue will be material.
 
   Our significant suppliers and customers, including those of our computer
outsourcing business, may not be Year 2000 compliant in a timely manner and any
noncompliance of these systems could have a material adverse effect on us.
 
   PKS Information Services, Inc., derives a substantial portion of its revenue
from projects that its subsidiary, PKS Systems Integration LLC, conducts
involving Year 2000 assessment and renovation services. These activities of PKS
Systems expose us to potential risks that may include problems with services
provided by PKS Systems to its customers and the potential for claims arising
under PKS Systems' customer contracts. PKS Systems' attempts to contractually
limit its exposure to liability for Year 2000 compliance issues may not be
effective.
 
Foreign currency exchange rate fluctuations or repatriation could result in
losses
 
   Our international expansion will cause our results of operations and the
value of our assets to be affected by the exchange rates between the U.S.
dollar and the currencies of the additional countries in which we have
operations and assets. In some of these countries, prices of our products and
services will be denominated in a currency other than the U.S. dollar. As a
result, we may experience economic losses solely as a result of foreign
currency exchange rate fluctuations, including a foreign currency's devaluation
against the dollar. We may also in the future acquire interests in companies
that operate in countries where the removal or conversion of currency is
restricted. In addition, these restrictions could be imposed in countries where
we conduct business after we begin our operations.
 
Environmental liabilities from our historical operations could be material
 
   Our operations and properties are subject to a wide variety of laws and
regulations relating to environmental protection, human health and safety.
These laws and regulations include those concerning the use and management of
hazardous and non-hazardous substances and wastes. We have made and will
continue to have to make significant expenditures relating to our environmental
compliance obligations. There may be times when we are not in compliance with
all these requirements.
 
   In connection with certain historical operations, we are a party to, or
otherwise involved in, legal proceedings under state and federal law involving
investigation and remediation activities at approximately 110 contaminated
properties. We could be held liable, jointly and severally, and without regard
to our own fault, for such investigation and remediation. The discovery of
additional environmental liabilities related to our historical operations or
changes in existing environmental requirements could have a material adverse
effect on us.

Significant future declines in cash flow from coal operations
 
   More than half of our net revenues for 1998 were attributable to our coal
mining operations. The level of cash flows generated in recent periods by our
coal operations will not continue after the year 2000. These cash flow levels
will decrease because the delivery requirements under our current long-term
contracts decline significantly after that date. Moreover, without those
contracts, our coal mining operations would not be able to operate profitably
by selling their production on the spot markets. A substantial majority of our
coal mining revenues are provided by three customer contracts.
 
Potential liabilities and claims arising from our coal operations could be
significant
 
   Our coal operations are subject to extensive laws and regulations that
impose stringent operational, maintenance, financial assurance, environmental
compliance, reclamation, restoration and closure requirements. These
requirements include those governing air and water emissions, waste disposal,
worker health and safety, benefits for current and retired coal miners, and
other general permitting and licensing requirements. We may not at all times be
in compliance with all of these requirements. Liabilities or claims associated
with this non-compliance could require us to incur material costs or suspend
production. Mine reclamation costs that exceed our reserves for these matters
also could require us to incur material costs.
 
Anti-takeover provisions in Level 3's charter and by-laws could limit our share
price and delay a change of management
 
   Our certificate of incorporation and by-laws contain provisions that could
make it more difficult or even prevent a third party from acquiring the company
without the approval of our incumbent board of directors. These provisions,
among other things:
 
  .  divide our board of directors into three classes, with members of each
     class to be elected in staggered three-year terms;
 
  .  prohibit stockholder action by written consent in place of a meeting;
 
  .  limit the right of stockholders to call special meetings of
     stockholders;
 
  .  limit the right of stockholders to present proposals or nominate
     directors for election at annual meetings of stockholders; and
 
  .  authorize our board of directors to issue preferred stock in one or more
     series without any action on the part of stockholders.
 
   These provisions could limit the price that investors might be willing to
pay in the future for shares of our common stock and significantly impede the
ability of the holders of our common stock to change management. In addition,
we have adopted a poison pill rights plan, which has anti-takeover effects. Our
rights plan, if triggered, will cause substantial dilution to a person or group
that attempts to acquire our company on terms not approved by our board of
directors. Provisions and agreements that inhibit or discourage takeover
attempts could reduce the market value of our common stock.
 
The terms of our debt agreements restrict us from making payments with respect
to our common stock
 
   Our ability to pay cash dividends on, or repurchase shares of, our common
stock is limited under the terms of our existing debt agreements. We do not
currently intend to pay any cash dividends for the foreseeable future.
 
Sales of shares by certain stockholders could depress our stock price
 
   We have registered approximately 4.68 million shares of common stock held by
former securityholders of XCOM Technologies, Inc. and GeoNet Communications,
Inc. These shares are not included in this offering. If
 
                                      S-15
<PAGE>
 
all or a substantial portion of these shares are sold in the public market,
our stock price may be adversely affected.
 
   The market price of our common stock could drop as a result of sales of a
large number of our shares in the public market after the offering. The
perception that sales may occur could have the same results. We will be
subject to a 90 day black-out following the date of this prospectus
supplement. During this black-out, we are not allowed to issue additional
common stock except in limited circumstances or unless Salomon Smith Barney
Inc. consents. One exception allows us to issue additional stock in connection
with acquisitions. A second exception applies if we are included in a major
market index.
 
   Our officers and directors will not be subject to any lock-up provision.
Additional shares are issuable under our benefit programs depending on the
extent to which our stock outperforms the S&P 500 by either rising at a higher
rate or falling at a lower rate. The number of such shares that would be
issued is based on a multiplier related to how much our stock outperforms the
S&P 500.
 
                                USE OF PROCEEDS
 
   Our net proceeds from this offering are estimated to be $     , or $
if the underwriters' over-allotment option is exercised in full, after
deducting estimated underwriting discounts and expenses. The net proceeds will
be used for the implementation of the Business Plan. A portion of the net
proceeds may also be used for working capital, general corporate purposes and
acquisitions. Although we evaluate potential acquisitions from time to time,
we have no agreement or understanding with any person to effect any material
acquisition.
 
   Pending such utilization, we intend to invest the net proceeds of this
offering in short-term investments.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
   This document contains forward looking statements and information that are
based on the beliefs of management as well as assumptions made by and
information currently available to the Company. When used in this document, the
words "anticipate," "believe," "estimate" and "expect" and similar expressions,
as they relate to the Company or its management, are intended to identify
forward-looking statements. Such statements reflect the current views of the
Company with respect to future events and are subject to certain risks,
uncertainties and assumptions. Should one or more of these risks or
uncertainties materialize, or should underlying assumptions prove incorrect,
actual results may vary materially from those described in this document. For a
more detailed description of these risks, please see "Risk Factors."
 
Results of Operations
 
   In late 1997, the Company announced a plan to increase substantially its
information services business and to expand the range of services it offers by
building an advanced, international, facilities-based communications network
based on IP technology. Since the Business Plan represents a significant
expansion of the Company's communications and information services business,
the Company does not believe that the Company's financial condition and results
of operations for prior periods will serve as a meaningful indication of the
Company's future financial condition or results of operations. The Company
expects to incur substantial net operating losses for the foreseeable future,
and there can be no assurance that the Company will be able to achieve or
sustain operating profitability in the future.
 
 Fourth Quarter 1998
 
   Since the Company's current Business Plan represents a significant expansion
of its communications and information services business and a change from its
previous business direction, year-over-year comparisons to previous quarters
may not serve as a meaningful indicator of the Company's future financial
condition or results of operations.
 
   For the fourth quarter of 1998, Level 3 reported consolidated revenues of
$96 million. Revenue for the full year 1998 totaled $392 million. The net loss
for the quarter was $35 million, or $0.11 a share. This includes a net pre-tax
gain of $116 million related to certain Company investments, which principally
represents a pre-tax gain of $90 million from the sale of the Company's
interests in Cable Michigan, Inc., gains recognized in connection with
issuances of stock by RCN Corporation and other asset dispositions. The net
loss also includes a $21 million charge for third party software and associated
development costs. Full year 1998 earnings of $730 million, or $2.42 a share,
include a $608 million gain attributable to the discontinued construction
operations. This gain was distributed to the former Class C shareholders at the
March 31, 1998 separation of Level 3 from the Construction Group. The 1998 net
loss from continuing operations was $202 million, or $0.67 per share.
 
   Revenue. Communications and information services revenue was $42 million, a
50% increase over fourth quarter 1997 revenue of $28 million. The year over
year increase was primarily a result of the inclusion of revenue from the
acquisitions completed during 1998--XCOM Technologies, Inc., GeoNet
Communications, Inc., and miknet Internet Based Services GmbH. The fourth
quarter also included revenue from new communication services that were
launched in 10 U.S. cities at the end of the third quarter of 1998.
 
   Other revenue of $54 million includes $50 million from coal mining, a 14%
decrease over fourth quarter 1997 coal revenue of $58 million. The decrease was
due to an acceleration of customer shipments in earlier quarters of 1998. Full
year 1998 coal revenue of $228 million was slightly ahead of full year 1997
revenue of $222 million.

   General and Administrative Expenses. Total general and administrative (G&A)
expenses for the quarter were $117 million, an increase of 388% over the fourth
quarter 1997 G&A expenses of $24 million. Fourth quarter 1998 results include
approximately $84 million in G&A expenses associated with the expansion of the
communications business, including expected additions in personnel. The Company
added 300 employees to the communications business during the fourth quarter of
1998, bringing the total number of employees for Level 3 Communications, Inc.
to approximately 2,200.
 
   Additional employee related expenses in the fourth quarter include $16
million of stock based compensation expense. During the second quarter of 1998,
Level 3 introduced its Outperform Stock Option program, which requires the
Company's stock to outperform the S&P 500 before the options have any value to
an employee. These expenses are accounted for in accordance with SFAS No. 123,
"Accounting For Stock-Based Compensation."
 
   Software Development. Approximately $20 million was charged against fourth
quarter earnings for third party software and associated development costs. The
charge was in accordance with new accounting rules (Statement of Position 98-
1), which changed the allocation allowances of items that can be expensed or
capitalized for internally developed software.
 
   Write-off of In-Process Research and Development. On April 23, 1998, the
Company completed the acquisition of XCOM Technologies, a privately held
company that developed certain components necessary for the Company to develop
an interface between its Internet Protocol-based network and the PSTN.
 
   The Company accounted for this transaction, valued at $154 million, as a
purchase. Of the total purchase price, $115 million was attributed to acquired
in-process research and development, and was taken as a non-deductible charge
to earnings in the second quarter of 1998.
 
   In October 1998, the SEC issued new guidelines, which are applied
retroactively, for valuing acquired research and development which are applied
retroactively. The Company believes its accounting for the acquisition was made
in accordance with generally accepted accounting principles and established
appraisal practices at the time of the acquisition. However, due to the
significance of the charge relative to the total value of the acquisition,
Level 3 plans to meet with the SEC to review the facts and assumptions. It is
possible that the SEC will require the Company to restate its results. A
reduction of any portion of this write-off would result in increased earnings
per share for Level 3 for 1998 and increase the goodwill associated with the
XCOM transaction, which is amortized over five years.
 
   Sale of Cable Michigan Interests. On November 10, 1998, the Company
announced the completion of the sale of Cable Michigan to Avalon Cable of
Michigan, Inc. Level 3 received approximately $129 million in cash, resulting
in a gain of approximately $90 million.
 
   Capital Expenditures. Capital expenditures for the quarter were $501
million, up from $265 million in the third quarter of 1998. The significant
increase was due to the acceleration of construction for both the inter-city
and certain local networks in the U.S. and Europe. Full year capital
expenditures totaled $910 million for 1998.
 
   Debt Offering. On December 2, 1998, Level 3 completed the sale of $833
million principal amount at maturity of 10.5% senior discount notes in a
transaction that was exempt from registration under the Securities Act of 1933.
The company intends to use the net proceeds of the offering, which were
approximately $486 million, to accelerate the implementation of the Business
Plan.

   Subsequent Events. In January 1999, Level 3 acquired BusinessNet Limited, a
leading London-based Internet service provider. This acquisition accelerated
Level 3's entry into the UK market as BusinessNet had an established market
focus on the financial and professional services community, specifically
through its IntraCity(TM) network, offering access to financial and other
Internet Protocol oriented services.

   Communications and Information Services revenue consists of computer
outsourcing revenue of $15 million, systems integration revenue of $14 million
and $8 million of communications revenue from XCOM, subsequent to its
acquisition in April 1998. XCOM's revenue is derived primarily from reciprocal
compensation fees paid by a regional telephone company. The comparable amounts
in 1997 for computer outsourcing and systems integration were $13 million and
$14 million, respectively. Computer outsourcing revenues increased due to the
addition of several new customers in late 1997 and early 1998. The acquisitions
of two small firms, for a total of $15 million in the second quarter of 1998,
resulted in $3 million of additional systems integration revenue. This increase
was offset by the loss of a major contract in early 1998 and a decline in
systems reengineering revenue. Revenue from communications services is expected
to increase in the fourth quarter as the Company recognizes additional revenue
from its IP related services.
 
   Coal mining revenue increased $14 million in the third quarter of 1998
compared to the same period in 1997. Additional alternate source coal sales to
Commonwealth Edison was partially offset by the expiration of other long term
contracts at the end of 1997 and lower priced contracts with new customers in
1998.
 
   Operating Expenses. Operating expenses increased 27% in 1998 to $47 million.
Margin, as a percentage of revenue, declined from 40% in 1997 to 32% in 1998
for information services businesses. The early termination of a large contract
in March of this year for the systems integration business resulted in lower
staff utilization and a decrease in margins. Margins for the computer
outsourcing business declined slightly in 1998. The start-up costs incurred to
establish a second data center in Phoenix were partially offset by a decline in
migration costs for new customers. Margins on coal sales increased 6% in the
third quarter of 1998. An increase in sales of higher margin alternate source
coal was partially offset by lower margins on coal sold from the Company's
mines. If current market conditions continue, the Company will experience a
significant decline in coal revenue and earnings over the next several years as
delivery requirements under long-term contracts decline as these long-term
contracts begin to expire.
 
   Depreciation and Amortization Expense. Depreciation and amortization expense
increased to $11 million in 1998 from $5 million in 1997. Depreciation on
equipment for computer outsourcing contracts and depreciation and amortization
of assets acquired in the XCOM acquisition are primarily responsible for the
increase. Additional depreciation is expected in the fourth quarter of 1998 as
the Company commences operations on additional portions of its IP network.
 
   General and Administrative Expenses. General and administrative expenses
increased significantly in 1998 to $96 million from $26 million in 1997
primarily due to the cost of activities associated with preparing for the
expected launch of the IP related services. The Company incurred incremental
compensation and travel costs for the substantial number of new employees that
have been hired to begin implementation of the Business Plan, legal costs
associated with obtaining licenses, agreements and technical facilities and
other
 
                                      S-20
<PAGE>
 
development costs associated with the Company's plans to begin offering
services in 15 U.S. cities by the end of 1998. In addition to the costs to
expand the communications and information services businesses, the Company
recorded $12 million of non-cash compensation and professional service expenses
in the third quarter of 1998 for expenses recognized under SFAS No. 123.
General and administrative costs are expected to increase significantly in
future periods as the Company implements the Business Plan.
 
   EBITDA. EBITDA which consists of earnings (losses) before interest, income
taxes, depreciation, amortization, non-cash stock-based compensation and other
non-operating income or expenses was $(25) million in 1998 and $18 million in
1997. The primary reason for the decrease between periods is the significant
increase in general and administrative expenses, described above, incurred in
connection with the implementation of the Company's Business Plan. EBITDA is
commonly used in the communications industry to analyze companies on the basis
of operating performance. EBITDA, however, should not be considered an
alternative to operating or net income as an indicator of the performance of
the Company's businesses, or as an alternative to cash flows from operating
activities as a measure of liquidity, in each case determined in accordance
with generally accepted accounting principles. See "Consolidated Condensed
Statements of Cash Flows."
 
   Interest Income. Interest income increased significantly in 1998 to $53
million from $8 million in 1997 as the Company's average cash, cash equivalents
and marketable securities balance approximated $3.7 billion in the third
quarter of 1998. The Company's average cash, cash equivalents and marketable
securities balance approximated $573 million in the comparable 1997 period.
Pending utilization of the cash equivalents and marketable securities in
implementing the Business Plan, the Company intends to invest the funds
primarily in government and governmental agency securities. This investment
strategy will provide for less yield on the funds, but is expected to reduce
the risk to principal prior to using the funds in implementing the Business
Plan.
 
   Interest Expense. Interest expense, net increased significantly in 1998 to
$46 million from $3 million in 1997. Interest expense increased substantially
due to the completion of the offering of $2 billion aggregate principal amount
of 9.125% Senior Notes due 2008 issued on April 23, 1998. The amortization of
debt issuance costs associated with the Senior Notes also increased interest
expense in the third quarter. The Company capitalized $5 million of interest
expense on network construction and systems development projects in the third
quarter of 1998.
 
   Other Expense. Other expense, net increased in 1998 to $27 million. The
increase in other expense is due to the losses incurred by the Company's equity
method investees, primarily RCN Corporation, Inc. ("RCN"). RCN is a full
service provider of local, long distance Internet and cable television services
to primarily residential users in the densely populated areas of the Northeast
United States. RCN is incurring significant costs in developing its business
plan including the acquisitions of several Internet service providers. The
Company recorded $22 million of equity losses attributable to RCN in the third
quarter of 1998. Partially offsetting these losses was the gain on RCN's stock
activity. In 1998, RCN issued stock through a public offering and for certain
acquisitions. These issuances resulted in a decrease in the Company's ownership
percentage but an increase in the Company's proportionate share of RCN's
equity. In accordance with its accounting policy, the Company recognized pre-
tax gains of $21 million and $4 million in the second and third quarters of
1998, respectively. Also included in other expense are equity earnings in
Commonwealth Telephone Enterprises, Inc., a Pennsylvania public utility
providing telephone service, equity in losses of Cable Michigan, Inc., a cable
television operator in the State of Michigan, and realized gains and losses on
the sale of marketable securities, investments and other assets each not
individually significant to the Company's results of operations.
 
   Income Tax Benefit. Income tax benefit differs from the statutory rate in
1998 primarily due to the $115 million nondeductible write-off of the in-
process research and development costs related to the XCOM acquisition. The
income tax provision in 1997 is slightly below the statutory rate due primarily
to depletion

allowances, tax exempt interest income and other individually insignificant
deductions for tax purposes in excess of those recognized for financial
reporting purposes.
 
   Discontinued Operations. In 1997, the United Kingdom implemented a "Windfall
Tax" against privatized British utilities. The one-time tax was 23% of the
difference between the value at the time of privatization and the utility's
current value. The total impact of the tax to Level 3, directly through its
investment in CE Electric UK, plc. and indirectly through its 30% ownership in
CalEnergy, was $63 million in the third quarter of 1997.

</TABLE>
 
   Revenue increased 22% to $296 million in 1998 for the nine months ended
September 30, 1998 compared to the same period in 1997. Systems integration
revenue, which consists mostly of Year 2000 projects, increased 41% to $42
million in 1998. The Company's systems integration business was still in its
early states of development in 1997 and the increase in revenue reflects the
strong demand for system integration services. Also contributing to the growth
of systems integration revenue was the acquisition of two small firms in the
second quarter of 1998 which contributed $3 million of revenue. Revenue for the
computer outsourcing business increased 24% to $46 million in 1998. The
increase is attributable to the addition of several new customers in 1997 and
early 1998. The remaining $14 million of communications revenue is primarily
attributable to XCOM which was acquired in April 1998.
 
   Mining revenue increased 8% in 1998 to $178 million. Increases in alternate
source coal sales were partially offset by a decrease in coal sold from the
Company's mines. Coal sold from the Company's mines declined due to the
expiration of a long-term contract in 1997.
 
   Operating Expenses. Operating expenses increased 18% to $138 million in
1998. Margin, as a percent of revenue, decreased 18% for the systems
integration business as the early termination of a large contract resulted in a
lower utilization of operating personnel. Gross margins for the computer
outsourcing business increased 9% during the first nine months of 1998. A
decrease in migration costs incurred in 1997 to implement new outsourcing
contracts was partially offset by start up costs incurred for the second data
center in Phoenix. Margins for the mining business increased by 3% in 1998. In
1998 an increase in higher margin alternate source coal sales were partially
offset by the reduced margins on coal sold from the Company's mines. In 1997,
margins were positively effected by the buyout of a spot coal contract. Under
the buyout, the customer was able to cancel its contract commitments by making
a payment equal to 60% of the price of the coal. These proceeds, with no
corresponding costs, resulted in the higher margin for the period.
 
   Depreciation and Amortization Expense. Depreciation and amortization expense
increased $9 million during the first nine months of 1998. Depreciation on the
computer equipment purchased for general and administrative personnel, computer
outsourcing businesses and the depreciation and amortization of equipment and
goodwill acquired in the XCOM acquisition, were primarily responsible for the
increase in depreciation expense.
 
   General and Administrative Expenses. General and administrative expenses
increased significantly in 1998 due to the expansion of the communications and
information services businesses. The hiring of
 
                                      S-22
<PAGE>
 
approximately 800 employees to implement the IP business led to increases in
compensation, relocation, travel and facilities expenses. In addition to
regular compensation, the Company recognized $23 million of non-cash expense
for stock options and warrants granted in the first nine months of 1998. The
Company also incurred significant professional service fees associated with the
initial development of a substantial, scalable business support infrastructure,
specifically designed to enable the Company to offer services efficiently to
its targeted customers. In addition, the Company also incurred legal costs
associated with obtaining licenses, agreements and technical facilities and
other development costs associated with the Business Plan.
 
   Write-off of In-Process Research and Development. Write-off of in-process
research and development was $115 million in 1998. The in-process research and
development costs were the portion of the purchase price allocated to the
telephone network-to-IP network bridge technology acquired by the Company in
the XCOM transaction and were estimated, through formal valuation, at $115
million. In accordance with generally accepted accounting principles, the $115
million was taken as a nondeductible charge against earnings in the second
quarter of 1998.
 
   EBITDA. EBITDA declined to $(18) million in 1998 from $64 million in 1997.
The increase in operating costs and general and administrative expenses
associated with the expanding communications and information services
businesses was primarily responsible for the decline.
 
   Interest Income. Interest income increased to $124 million in 1998 from $23
million in 1997. The $1.16 billion proceeds from the sale of the energy assets
on January 2, and the $1.94 billion proceeds from the debt offering on April
28, were primarily responsible for the average cash, cash equivalents and
marketable securities balance increasing from $514 million to $2.9 billion for
the nine months ending September 30, 1997 and 1998, respectively. The increase
in the average balance was directly responsible for the increase in interest
income.
 
   Interest Expense. Interest expense, net increased to $86 million in 1998.
The increase in interest expense is directly attributable to the interest on
the Senior Notes and the amortization of the deferred debt issuance costs. The
interest expense for 1997 is primarily attributable to the debt on the
California toll road which is nonrecourse to the Company. The Company
capitalized $6 million of interest expense on network construction and systems
development projects in 1998.
 
   Other Expense. Other expense, net increased substantially in 1998 to $53
million from $11 million in 1997 due primarily to increased losses recognized
by the Company's equity method investee, RCN. The Company's share of these
losses approximated $75 million in 1998. RCN recognized a charge to earnings of
approximately $52 million (of which the Company's share was $24 million) with
respect to certain costs of the acquisitions associated with in process
research and development activities. Partially offsetting these losses was the
gain on RCN's stock activity of $25 million. In 1998, RCN issued stock through
a public offering and for certain acquisitions. These issuances resulted in a
decrease in the Company's ownership percentage but an increase in the Company's
proportionate share of RCN's equity. It is the Company's policy to recognize a
gain for the increase in the Company's proportionate share of RCN's equity.
Also included in other expense are equity earnings in Commonwealth Telephone
Enterprises, Inc. ("Commonwealth Telephone"), equity in losses of Cable
Michigan, Inc., and realized gains and losses on the sale of marketable
securities, investments and other assets each not individually significant to
the Company's results of operations.
 
   Income Tax (Provision) Benefit. Income tax benefit differs from the expected
statutory rate primarily due to the nondeductible write-off of the in-process
research and development costs allocated in the XCOM transaction. The effective
rate in 1997 is lower than the expected rate due to depletion allowances and
tax exempt interest income.
 
   Discontinued Operations. Discontinued operations includes the one-time gain
of $608 million recognized upon the distribution of the Construction Group to
stockholders on March 31, 1998. Also included in discontinued operations is the
gain, net of tax, of $324 million from the Company's sale of its energy assets
to
 
                                      S-23
<PAGE>
 
CalEnergy on January 2, 1998. In 1997, the United Kingdom implemented a
"Windfall Tax" against privatized British utilities. The total impact of the
tax to Level 3, directly through its investment in CE Electric UK, plc. and
indirectly through its 30% ownership in CalEnergy, was $63 million in 1997.
 
Financial Condition--September 30, 1998
 
   The Company's working capital increased substantially during 1998 due
primarily to the sale of the Company's energy assets to CalEnergy for $1.16
billion on January 2, 1998, and the $1.94 billion of proceeds from the issuance
of Senior Notes on April 28, 1998. The Company's working capital increased $2.1
billion to $3.5 billion on September 30, 1998. The Company's operations used
$16 million of cash during the first nine months of 1998, primarily for the
payment of 1998 estimated income taxes and the costs in implementing the
Business Plan. These items were partially offset by funds provided by coal
mining operations, the receipt of a $45 million federal tax refund, a $26
million payment from INTERNEXT, LLC, the acquirer of the right to use 24 fibers
and associated facilities along the Company's entire U.S. intercity network,
and interest income. The initial interest payment on the Company's 9.125%
Senior Notes Due 2008, $92 million, was made on November 2, 1998.
 
   Investing activities include the purchase of $5,132 million of marketable
securities, the sales and maturities of marketable securities of $2,882
million, $409 million of capital expenditures, primarily for the expanding IP
and information services business and $24 million of investments, principally
$15 million for information services businesses. The Company also realized $26
million of proceeds from the sale of property, plant and equipment and other
assets.
 
   Financing sources in 1998 consisted primarily of the net proceeds of $1.94
billion from the sale of Senior Notes in April, the conversion of 2.3 million
shares of Class C Stock, with a redemption value of $122 million, into 21
million shares of Level 3 common stock (formerly Class D Stock) in January,
proceeds from the sale of Level 3 common stock of $21 million and the exercise
of stock options for $7 million. In 1998, Level 3 issued $183 million of stock
for the acquisition of several IP businesses and reflected in the equity
accounts the $164 million fair value of the issuance and forced conversion of
the Class R Stock during the first nine months of 1998.
 
Liquidity and Capital Resources
 
   Since late 1997, the Company has substantially increased the emphasis it
places on and the resources devoted to its communications and information
services business. The Company has commenced the implementation of a plan to
become a facilities-based provider (that is, a provider that owns or leases a
substantial portion of the plant, property and equipment necessary to provide
its services) of a broad range of integrated communications services. To reach
this goal, the Company plans to expand substantially the business of its
subsidiary, PKS Information Services, Inc., ("PKSIS") and to create, through a
combination of construction, purchase and leasing of facilities and other
assets, an international, end-to-end, facilities-based communications network.
The Company is designing its network based on IP technology in order to
leverage the efficiencies of this technology to provide lower cost
communications services.
 
   The implementation of the Business Plan requires significant capital
expenditures, a substantial portion of which will be incurred before any
significant related revenues from the Business Plan are expected to be
realized. These expenditures, together with the associated early operating
expenses, will result in substantial negative operating cash flow and
substantial net operating losses for the Company for the foreseeable future.
Although the Company believes that its cost estimates and build-out schedule
are reasonable, there can be no assurance that the actual construction costs or
the timing of the expenditures will not deviate from current estimates. The
Company's capital expenditures in connection with the Business Plan were
approximately $910 million in 1998. The Company estimates that its capital
expenditures in connection with the Business Plan will range from $2 billion to
$3 billion in 1999. The Company's current liquidity in addition to the net
proceeds
 
                                      S-24
<PAGE>
 
from the Senior Notes, the cost sharing agreement with INTERNEXT and the
realization of value of certain non-core assets, should be sufficient to fund
the currently committed portions of the Business Plan.
 
   The Company estimates that the implementation of the Business Plan, as
currently contemplated, requires between $8 and $10 billion over the 10-year
period of the plan. The Company's ability to implement the Business Plan and
meet its projected growth is dependent upon its ability to secure substantial
additional financing in the future. The Company expects to meet its additional
capital needs with the proceeds from sales or issuance of equity securities,
credit facilities and other borrowings, or additional debt securities. The
Senior Notes were issued under an indenture which permits the Company and its
subsidiaries to incur substantial amounts of debt. In addition, the Company may
sell or dispose of existing businesses or investments to fund portions of the
Business Plan. The Company may sell or lease capacity, its conduits or access
to its conduits. There can be no assurance that the Company will be successful
in producing sufficient cash flow, raising sufficient debt or equity capital on
terms that it will consider acceptable, or selling or leasing fiber optic
capacity or access to its conduits, or that proceeds of dispositions of the
Company's assets will reflect the assets' intrinsic value. Further, there can
be no assurance that expenses will not exceed the Company's estimates or that
the financing needed will not likewise be higher than estimated. Failure to
generate 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 implementation of the Business Plan.
 
   There can be no assurance that the Company will be able to obtain such
financing if and when it is needed or that, if available, such financing will
be on terms acceptable to the Company. If the Company is unable to obtain
additional financing when needed, it may be required to scale back
significantly its Business Plan and, depending upon cash flow from its existing
businesses, reduce the scope of its plans and operations.
 
   In connection with implementing the Business Plan, management will continue
reviewing the existing businesses of the Company to determine how those
businesses will complement the Company's focus on communications and
information services. If it is decided that an existing business is not
compatible with the communications and information services business, the
Company may dispose of that business.
 
   On June 4, 1998, Cable Michigan announced that its board of directors had
reached a definitive agreement to sell the company to Avalon Cable for $40.50
per share in a cash-for-stock transaction. Level 3 received approximately $129
million when the transaction closed on November 6, 1998 and recognized pre-tax
gain of approximately $90 million in the fourth quarter.
 
   New Accounting Pronouncements. In 1997, the Financial Accounting Standards
Board issued SFAS No. 131, "Disclosures about Segments of an Enterprise and
Related Information" ("SFAS No. 131"), which changes the way public companies
report information about segments. SFAS No.131, which is based on the
management approach to segment reporting includes requirements to report
selected segment information quarterly, and entity-wide disclosures about
products and services, major customers, and geographic data. This statement is
effective for financial statements for periods beginning after December 15,
1997. The Company will reflect the adoption of SFAS No. 131 in its December 31,
1998 financial statements.
 
   On March 4, 1998, the Accounting Standards Executive Committee ("AcSEC")
issued Statement of Position 98-1, "Accounting for the Costs of Computer
Software Developed or Obtained for Internal Use" ("SOP 98-1"). The effective
date of this pronouncement is for fiscal years beginning after December 15,
1998, however, earlier application is encouraged and the Company is accounting
for these costs in accordance with SOP 98-1 in 1998.
 
   On April 3, 1998, the AcSEC issued Statement of Position 98-5, "Reporting on
the Costs of Start-Up Activities" ("SOP 98-5"), which provides guidance on the
financial reporting of start-up and organization costs. It requires costs of
start-up activities and organization costs to be expensed as incurred. SOP 98-5
is effective for financial statements for fiscal years beginning after December
15, 1998. The Company expects that
 
                                      S-25
<PAGE>
 
the charge to earnings resulting from the adoption of SOP 98-5 will not be
significant relative to the Company's financial position or results of
operations.
 
   On June 15, 1998, the FASB issued Statement of Financial Accounting
Standards No. 133, "Accounting for Derivative Instruments and Hedging
Activities" ("SFAS No. 133"). SFAS No. 133 is effective for fiscal years
beginning after June 15, 1999 (January 1, 2000 for the Company). SFAS No. 133
requires that all derivative instruments be recorded on the balance sheet at
the fair value. Changes in the fair value of derivatives are recorded each
period in current earnings or other comprehensive income, depending on whether
a derivative is designated as part of a hedge transaction and, if it is, the
type of hedge transaction. The Company does not currently utilize derivative
instruments, therefore the adoption of SFAS No. 133 is not expected to have a
significant effect on the Company's results of operations or its financial
position.
 
   Year 2000. The Company is in the process of conducting a review of its
computer systems, including the computer systems used in the Company's computer
outsourcing business, to identify systems that could be affected by the "Year
2000" computer issue. Based upon this review, the Company will develop and
implement a plan to resolve any related issues. The Year 2000 issue results
from computer programs written with date fields of two digits, rather than four
digits, thus resulting in the inability of computer programs to distinguish
between the year 1900 and 2000. The Company expects that its Year 2000
compliance project will be completed before the Year 2000 date change. During
the execution of this project, the Company has and will continue to incur
internal staff costs as well as consulting and other expenses. These costs will
be expensed, as incurred, in compliance with generally accepted accounting
principles. The expenses associated with this project, as well as the related
potential effect on the Company's earnings, are not expected to have a material
effect on its future operating results or financial condition. The source of
funds for Year 2000 compliance costs will be cash on hand, and are expected to
represent an immaterial amount of the Company's overall information systems
budget. There can be no assurance, however, that the Year 2000 problem will not
have a material adverse effect on the Company's business, financial condition,
competitive position and results of operations.
 
   The Company anticipates that its plan to resolve related Year 2000 issues
will be a multiphase plan that would include (1) assessment of the potential
Year 2000 issues, (2) a detailed action plan based upon the results of its
assessment of the potential issues, (3) remediation of systems and products
that are identified in the assessment and the detailed plan as requiring
correction or elimination, (4) testing of the results of the remediation
efforts to assess Year 2000 readiness and (5) the implementation of the
remediated systems and products. Additional details of the Company's plan will
be outlined as they are finalized.
 
   The Company's wholly owned subsidiary, Level 3 Communications, LLC is a new
company that is implementing new technologies to provide IP technology-based
communications services to its customers. This company has adopted a strategy
to select technology vendors and suppliers that provide products that are
represented by such vendors and suppliers to be Year 2000 compliant. In
negotiating its vendor and supplier contracts, the company secures Year 2000
warranties that address the Year 2000 compliance of the applicable product(s).
As part of the Company's Year 2000 compliance program, plans will be put into
place to test these products to confirm they are Year 2000 compliant.
 
   The Company has initiated communications with its significant suppliers and
customers, including those that will provide leased communications capacity to
the Company as well as those of PKSIS's computer outsourcing business and, in
particular, vendors of that business's computer outsourcing operating
environments, to determine the extent to which the Company is vulnerable to the
failure by such parties to remediate Year 2000 compliance issues. No assurance
can be given, however, that the systems will be made Year 2000 compliant in a
timely manner or that the noncompliance of the systems of any of these parties
would not have a material adverse effect on the Company's business, financial
condition, competitive position and results of operations.

   PKS Systems Integration LLC ("PKS Systems"), a subsidiary of PKSIS, provides
a wide variety of information technology services to its customers. In fiscal
year 1997, approximately 80% of the revenue generated by PKS Systems related to
projects involving Year 2000 assessment and renovation services performed by
PKS Systems for its customers. These contracts generally require PKS Systems to
identify date-affected fields in certain application software of its customers
and, in many cases, PKS Systems undertakes efforts to remediate those date-
affected fields so that Year 2000 data may be processed. Thus, Year 2000 issues
affect many of the services PKS Systems provides to its customers. This exposes
PKS Systems to potential risks that may include problems with services provided
by PKS Systems to its customers and the potential for claims arising under PKS
Systems' customer contracts. PKS Systems attempts to contractually limit its
exposure to liability for Year 2000 compliance issues. However, there can be no
assurance as to the effectiveness of these contractual limitations.
 
   The expenses associated with this project by PKSIS, as well as the related
potential effect on the Company's earnings, are not expected to have a material
effect on its future operating results or financial condition. There can be no
assurance, however, that the Year 2000 problem, and any loss incurred by any
customers of PKSIS as a result of the Year 2000 problem, will not have a
material adverse effect on the Company's financial condition and results of
operations.

                               INDUSTRY OVERVIEW
 
History and Industry Development
 
   Telecommunications Industry. Prior to its court-ordered breakup in 1984 (the
"Divestiture"), AT&T largely monopolized the telecommunications services in the
United States even though technological developments had begun to make it
economically possible for companies (primarily entrepreneurial enterprises) to
compete for segments of the communications business.
 
   The present structure of the U.S. telecommunications market is largely the
result of the Divestiture. As part of the Divestiture, seven local exchange
holding companies were created to offer services in geographically defined
areas called LATAs. The RBOCs were separated from the long distance provider,
AT&T, resulting in the creation of two distinct market segments: local exchange
and long distance. The Divestiture provided for direct, open competition in the
long distance segment.
 
   The Divestiture did not provide for competition in the local exchange
market. However, several factors served to promote competition in the local
exchange market, including: (i) customer desire for an alternative to the
RBOCs, also referred to as the ILECs; (ii) technological advances in the
transmission of data and video requiring greater capacity and reliability than
ILEC networks were able to accommodate; (iii) a monopoly position and rate of
return-based pricing structure which provided little incentive for the ILECs to
upgrade their networks; and (iv) the significant fees, called "access charges,"
that long distance carriers were required to pay to the ILECs to access the
ILECs' networks.
 
   The first competitors in the local exchange market, designated as CAPs by
the FCC, were established in the mid-1980s. Most of the early CAPs were
entrepreneurial enterprises that operated limited networks in the central
business districts of major cities in the United States where the highest
concentration of voice and data traffic is found. Since most states prohibited
competition for local switched services, early CAP services primarily consisted
of providing dedicated, unswitched connections to long distance carriers and
large businesses. These connections allowed high-volume users to avoid the
relatively high prices charged by ILECs for dedicated, unswitched connections.
 
   As CAPs proliferated during the latter part of the 1980s, certain federal
and state regulators issued rulings which favored competition and promised to
open local markets to new entrants. These rulings allowed CAPs to offer a
number of new services, including, in certain states, a broad range of local
exchange services, including local switched services. Companies providing a
combination of CAP and switched local services are sometimes referred to as
CLECs. This pro-competitive trend continued with the passage of the
Telecommunications Act of 1996 (the "Telecom Act"), which provided a legal
framework for introducing competition to local telecommunications services
throughout the United States.
 
   Over the last three years, several significant transactions have been
announced representing consolidation of the U.S. telecom industry. Among the
ILECs, Bell Atlantic Corporation and NYNEX Corporation merged in August 1997,
Pacific Telesis Group and SBC Communications Inc. merged in April 1997, SBC
Communications Inc. and Ameritech Corporation have proposed a merger and GTE
Corporation and Bell Atlantic Corporation have proposed a merger. Major long
distance providers have sought to enhance their positions in local markets,
through transactions such as AT&T's acquisition of Teleport Communications
Group and proposed acquisition of Tele-Communications, Inc. and WorldCom's
mergers with MFS and Brooks Fiber Properties. They have also sought to
otherwise improve their competitive positions, through transactions such as
WorldCom's merger with MCI.
 
   Many international markets resemble that of the United States prior to the
Divestiture. In many countries, traditional telecommunications services have
been provided through a monopoly provider, frequently controlled by the
national government, such as a Post, Telegraph and Telephone Company. In recent
years, there has been a trend toward liberalization of many of these markets,
particularly in Europe. Led by the introduction of
 
                                      S-28
<PAGE>
 
competition in the United Kingdom, the European Union mandated open competition
as of January 1998. Similar trends are emerging, albeit more slowly, in Asia.
 
   Internet Industry. The Internet is a global collection of interconnected
computer networks that allows 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 that was created 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 academic
organizations. 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
IP, an inter-networking standard that enables communication across the Internet
regardless of the hardware and software used.
 
   Over time, as businesses have begun to utilize e-mail, file transfer and,
more recently, intranet and extranet services, commercial usage has become a
major component of Internet traffic. In 1989, the U.S. government effectively
ceased directly funding any part of the Internet backbone. In the mid-1990s,
contemporaneous with the increase in commercial usage of the Internet, a new
type of provider called an ISP became more prevalent. ISPs offer access, e-
mail, customized content and other specialized services and products aimed at
allowing both commercial and residential customers to obtain information from,
transmit information to, and utilize resources available on the Internet.
 
   ISPs generally operate networks composed of dedicated lines leased from
ILECs, CLECs and ISPs using IP-based switching and routing equipment and
server-based applications and databases. Customers are connected to the ISP's
POP by facilities obtained by the customer or the ISP from either ILECs or
CLECs through a dedicated access line or the placement of a circuit-switched
local telephone call to the ISP.
 
   IP Communications Technology. There are two widely used switching
technologies in currently deployed communications networks: circuit-switching
systems and packet-switching systems. Circuit-switch based communications
systems establish a dedicated channel for each communication (such as a
telephone call for voice or fax), maintain the channel for the duration of the
call, and disconnect the channel at the conclusion of the call. Packet-switch
based communications systems format the information to be transmitted, such as
e-mail, voice, fax and data into a series of shorter digital messages called
"packets." Each packet consists of a portion of the complete message plus the
addressing information to identify the destination and return address.
 
   Packet-switch based systems offer several advantages over circuit-switch
based systems, particularly the ability to commingle packets from several
communications sources together simultaneously onto a single channel. For most
communications, particularly those with bursts of information followed by
periods of "silence," the ability to commingle packets provides for superior
network utilization and efficiency, resulting in more information being
transmitted through a given communication channel. There are, however, certain
disadvantages to packet-switch based systems as currently implemented. Rapidly
increasing demands for data, in part driven by the Internet traffic volumes,
are straining capacity and contributing to latency (delays) and interruptions
in communications transmissions. In addition, there are concerns about the
adequacy of the security and reliability of packet-switch based systems as
currently implemented.
 
   Initiatives are under way to develop technology to address these
disadvantages of packet-switch based systems. The Company believes that the
evolving IP standard, which is a market based standard broadly adopted in the
Internet and elsewhere, will remain a primary focus of these development
efforts. The Company expects the benefits of these efforts to be improved
communications throughout, reduced latency and declining networking hardware
costs.

Telecommunications Services Market
 
   Overview of U.S. Market. The traditional U.S. market for telecommunications
services can be divided into three basic sectors: long distance services, local
exchange services and Internet access services. In 1997, it is estimated that
local exchange services accounted for revenues of $92.4 billion, long distance
services generated revenues of $104.6 billion and Internet services revenues
totaled $6.3 billion. Revenues for both local exchange and long distance
services include amounts charged by long distance carriers and subsequently
paid to ILECs (or, where applicable, CLECs) for long distance access.
 
   Long Distance Services. A long distance telephone call can be envisioned as
consisting of three segments. Starting with the originating customer, the call
travels along an ILEC or CLEC 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 long distance carrier's network near where the call
will terminate. The call is then sent from this POP along an ILEC or CLEC
network to the terminating customer. Long distance carriers provide only the
connection between the two local networks, and pay access charges to LECs for
originating and terminating calls.
 
   The following diagram is a simplified illustration of a typical long
distance call:
 
                              [CHART APPEARS HERE]
 
   Local Exchange Services. A local call is one that does not require the
services of a long distance carrier. In general, the local exchange carrier
connects end user customers within a LATA and also provides the local portion
of most long distance calls.

   The following diagram is a simplified illustration of a typical local call:
 
                              [CHART APPEARS HERE]
 
   Internet Service. Internet services are generally provided in at least two
distinct segments. A local network connection is required from the ISP customer
to the ISP's local facilities. For large, communication-intensive users and for
content providers, these connections are typically unswitched, dedicated
connections provided by ILECs or CLECs, either as independent service providers
or, in some cases, by a company which is both a CLEC and an ISP. For
residential and small/medium business users, these connections are generally
PSTN connections obtained on a dial-up access basis as a local exchange
telephone call. Once a local connection is made to the ISP's local facilities,
information can be transmitted and obtained over a packet-switched IP data
network, which may consist of segments provided by many interconnected networks
operated by a number of ISPs. This collection of interconnected networks makes
up the Internet. A key feature of Internet architecture and packet-switching is
that a single dedicated channel between communication points is never
established, which distinguishes Internet-based services from the PSTN.
 
   The following diagram is a simplified illustration of a typical Internet
access service:
 
                              [CHART APPEARS HERE]
 
   Overview of International Market. The traditional market for
telecommunications services outside of the United States can also be divided
into three basic sectors: long distance services, local exchange services and
Internet access services. In 1997, it is estimated that local exchange services
accounted for revenues of $116.6 billion, long distance services generated
revenues of $193.7 billion and Internet services revenues totaled $4.8 billion.

   IP Network and Interconnection. The Company is designing the Level 3 network
to be optimized for IP-based communications, rather than circuit-switch based
communications such as that utilized by the PSTN. The network is being designed
with the goal of providing the Company with the ability to adapt its
facilities, hardware and software to future technology developments in packet-
switch based communications systems.
 
   There are many IP networks currently in operation. While generally adequate
for data transmission needs, these networks usually are not configured to
provide the voice quality, real-time communications requirements of a
traditional telephone call. With current technology, this quality can only be
achieved by providing a substantial cushion of communications capacity. In
addition, existing voice-over IP services generally require either customized
end-user equipment or the dialing of "access codes" or the following of other
special procedures to initiate a call. There are also concerns about the
reliability and security of existing IP-voice networks.
 
   The Company is developing its IP-voice services so that customers will not
be required to dial access codes or follow other special procedures to initiate
a call. The Company and other technology providers are developing soft-switch
technology to enable the transmission of traffic seamlessly between a router-
based IP network and the circuit-based PSTN. This technology is expected to
provide the Level 3 network with the same ubiquity of the PSTN. Specifically,
the Company's technology is expected to provide Level 3 with (1) the ability to
originate PSTN telephone traffic from an ILEC's switch (when the origination
point is not on the Level 3 network), (2) route the traffic over the Level 3
network and (3) deliver the traffic either (a) directly to its destination (if
the destination is on the Level 3 network) or (b) to an interconnection point
where the traffic is transferred back to the PSTN (the routing of traffic to
this interconnection point will be determined based on a least-cost routing
criteria). When this capability is fully developed, Level 3 expects to be able
to obtain the benefits of packet-switch based communications protocols on its
network, while allowing its customers to use their existing equipment,
telephone numbers and dialing procedures, without additional access codes, for
routing the call to the Level 3 network. Level 3 believes that by building its
own network with significant excess capacity, expandability and the latest
technological advances in network design and equipment and having the ability
to route calls over the PSTN in the event of service disruptions, the other
significant issues associated with IP-voice transmission (quality, latency,
reliability and security) should be satisfactorily addressed. The Company plans
to begin commercially testing its IP-voice transmission services in selected
markets in the second quarter of 1999. See "Risk Factors--A failure to develop
or acquire satisfactory voice or fax technology for Internet Protocol networks
could adversely affect our business."
 
   On November 16, 1998, Level 3 and Bell Communications Research Inc.
announced the merger of their respective specifications for a new protocol
designed to bridge between the current circuit-based PSTN and emerging IP
technology based networks.
 
   The merged specification, called the Media Gateway Control Protocol, or
MGCP, represents a combination of the Internet Protocol Device Control, or IPDC
specification developed by a consortium formed by Level 3 and made up of
leading communications hardware and software companies, and the Simple Gateway
Control protocol, developed by Bell Communications Research Inc. and Cisco
Systems, Inc. The MGCP specification is available without a fee to service
providers and hardware and software vendors interested in implementing it in
their networks and equipment.
 
   The significance of MGCP is that when implemented it will provide customers
with a seamless interconnection between traditional PSTN and the newer IP
technology networks. Level 3 believes that this integration will enable
customers to benefit from the lower cost of IP network services, including
voice and fax, without modifying existing telephone and fax equipment or
dialing access codes. Level 3 plans to use MGCP in the development of its own
network.

                                    BUSINESS
 
   Level 3 engages in the information services, communications and coal mining
businesses through ownership of operating subsidiaries and substantial equity
positions in public companies. In late 1997, the Company announced the Business
Plan to increase substantially its information services business and to expand
the range of services it offers by building an advanced, international
facilities-based communications network based on IP technology.
 
History
 
   The Company was incorporated as Peter Kiewit Sons', Inc. in Delaware in 1941
to continue a construction business founded in Omaha, Nebraska in 1884. In
subsequent years, the Company invested a portion of the cash flow generated by
its construction activities in a variety of other businesses. The Company
entered the coal mining business in 1943, the telecommunications business
(consisting of MFS and, more recently, an investment in C-TEC and its
successors RCN, Commonwealth Telephone and Cable Michigan, Inc. ("Cable
Michigan")) in 1988, the information services business in 1990 and the
alternative energy business, through CalEnergy, in 1991. Level 3 also has made
investments in several development-stage ventures.
 
   In the last three years, the Company has distributed to its stockholders a
portion of its telecommunications business, split off its construction business
and sold its investments in the alternative energy sector. In 1995, the Company
distributed to the holders of Class D Stock all of its shares of MFS. In the
seven years from 1988 to 1995, the Company invested approximately $500 million
in MFS; at the time of the distribution to stockholders in 1995, the Company's
holdings in MFS had a market value of approximately $1.75 billion. In December
1996, MFS was purchased by MCI WorldCom in a transaction valued at $14.3
billion.
 
   In December 1997, the Company's stockholders ratified the decision of the
Board to effect the split-off separating the Construction Group. As a result of
the split-off, which was completed on March 31, 1998, the Company no longer
owns any interest in the Construction Group. In conjunction with the split-off,
the Company changed its name to "Level 3 Communications, Inc.," and the
Construction Group changed its name to "Peter Kiewit Sons', Inc."
 
   In January 1998, the Company completed the sale to CalEnergy of its energy
investments, consisting primarily of a 24% equity interest in CalEnergy. The
Company received proceeds of approximately $1.16 billion from this sale, and as
a result recognized an after-tax gain of approximately $324 million in 1998.
 
   On November 6, 1998, Avalon Cable of Michigan, Inc. acquired all the
outstanding stock of Cable Michigan. Level 3 received approximately $129
million in cash for its interest in Cable Michigan and recognized a pre-tax
gain of approximately $90 million.
 
Business Plan
 
   Since late 1997, the Company has substantially increased the emphasis it
places on and the resources devoted to its communications and information
services business. Since that time, the Company has become a facilities-based
provider (that is, a provider that owns or leases a substantial portion of the
plant, property and equipment necessary to provide its services) of a broad
range of integrated communications services. The Company has expanded
substantially the business of its subsidiary PKSIS and is creating, through a
combination of construction, purchase and leasing of facilities and other
assets, an international, end-to-end, facilities-based communications network.
The Company is designing the Level 3 network based on IP technology in order to
leverage the efficiencies of this technology to provide lower cost
communications services.
 
   Market and Technology Opportunity. The Company believes that, as technology
advances, a comprehensive range of both consumer and business communications
and information services will be provided over networks utilizing IP
technology. These services will include traditional voice services and fax
 
                                      S-33
<PAGE>
 
transmission, as well as other data services such as Internet access and
virtual private networks. The Company believes this shift has begun, and over
time should accelerate, for the following reasons:
 
  .  Efficiency.  As a packet-switched technology, IP technology generally
     uses network capacity more efficiently than the traditional circuit-
     switched PSTN. Therefore, certain services can be provided for lower
     cost over a network using IP technology, particularly those services
     which are not timing sensitive, such as e-mail and file transfer.
 
  .  Flexibility. IP technology is an open protocol (a non-proprietary,
     published standard) which allows for market driven development of new
     uses and applications for IP networks. In contrast, the PSTN is based on
     proprietary protocols, which are governed and maintained by
     international standards bodies that are generally controlled by
     government-affiliated entities and slow to accept change.
 
  .  Improving Technologies. The Company believes that IP's market based
     protocol will likely lead to technological advances that will address
     the problems currently associated with IP-based applications, including
     the difficulty achieving seamless interconnection with the PSTN, latency
     (delay through the network which can negatively affect timing sensitive
     communications such as voice and fax) and concerns about adequate
     security and reliability.
 
  .  Standardized Interface. Web browsers were developed for the public
     Internet and are usable with many IP networks. Web browsers can provide
     a standardized interface to data and applications on an IP network.
     Standardized interfaces make it easier for end users to access and use
     these resources.
 
   Level 3's Strategy. The Company is seeking to capitalize on the benefits of
IP technology by pursuing the Business Plan. Key elements of the Company's
strategy include:
 
  .  Become the Low Cost Provider of Communications Services. Level 3 is
     designing its network to provide high quality communications services at
     a lower cost and to incorporate more readily future technological
     improvements relative to older, less adaptable networks. For example,
     the Level 3 network is being constructed using multiple conduits to
     allow the Company to cost-effectively deploy future generations of
     optical networking components and thereby expand capacity and reduce
     unit costs. In addition, the Company's strategy is to maximize the use
     of open, non-proprietary interfaces in the design of its network
     software and hardware. This approach is intended to provide Level 3 with
     the ability to purchase the most cost-effective network equipment from
     multiple vendors.
 
  .  Offer a Comprehensive Range of Communications Services. As the Business
     Plan is implemented, the Company intends to provide a comprehensive
     range of communications services over the Level 3 network, including
     private line, colocation, Internet access, managed modem and voice and
     fax transmission service. The Company is currently offering all of these
     services other than voice and fax transmission services.
 
  .  Provide Seamless Interconnection to the PSTN. The Company and other
     technology providers are developing technology to allow seamless
     interconnection of the Level 3 network with the PSTN. A seamless
     interconnection will allow customers to use the Level 3 network,
     including voice and fax, without modifying existing telephone and fax
     equipment or existing dialing procedures (that is, without the need to
     dial access codes or follow other similar special procedures).
 
  .  Accelerate Market Roll-out. To support the launch of its services and
     develop a customer base in advance of completing the construction of its
     network, Level 3 has begun offering services in 17 U.S. cities and in
     London and Frankfurt over leased local and intercity facilities. Over
     time, these leased networks will be displaced by networks that the
     Company is constructing.
 
  .  Expand Target Market Opportunities. The Company has a direct sales force
     that targets large businesses. In addition, the Company has developed
     alternative distribution channels to gain access to a substantially
     larger base of potential customers than the Company could otherwise
     initially address through its direct sales force. Through the
     combination of a direct sales force and alternative distribution
     channels, the Company believes that it will be able to rapidly increase
     revenue-producing traffic on its network.
 
 
                                      S-34
<PAGE>
 
  .  Develop Advanced Business Support Systems. The Company is developing a
     substantial, scalable and web-enabled business support system
     infrastructure specifically designed to enable the Company to offer
     services efficiently to its targeted customers. The Company believes
     that this system will reduce our operating costs, give our customers
     direct control over some of the services they buy from us and allow us
     to grow rapidly without redesigning the architecture of its business
     support system.
 
  .  Leverage Existing Information Services Capabilities. The Company is
     expanding its existing capabilities in computer network systems
     integration, consulting, outsourcing and software reengineering, with
     particular emphasis on the conversion of legacy software systems to
     systems that are compatible with IP networks and web browser access.
 
  .  Attract and Motivate High Quality Employees. The Company has developed
     programs designed to attract and retain employees with the technical
     skills necessary to implement the Business Plan. The programs include
     the Company's Shareworks stock purchase plan and its Outperform Stock
     Option program.
 
  Competitive Advantages. The Company believes that it has the following
competitive advantages that, together with its strategy, will assist it in
implementing the Business Plan:
 
  .  Experienced Management Team. Level 3 has assembled a management team
     that it believes is well suited to implement the Business Plan. Most of
     Level 3's senior management was involved in leading the development and
     marketing of telecommunication products and in designing, constructing
     and managing intercity, metropolitan and international networks.
 
  .  Opportunity to Create a More Readily Upgradable Network
     Infrastructure. Level 3's network design strategy seeks to take
     advantage of recent innovations, incorporating many of the features that
     are not present in older communication networks and provides Level 3
     flexibility to take advantage of future development and innovation.
 
  .  Integrated End-to-End Network Platform. Level 3's strategy is to deploy
     network infrastructure in major metropolitan areas and to link these
     networks with significant intercity networks in North America and
     Europe. The Company believes that the integration of its local and
     intercity networks will expand the scope and reach of its on-net
     customer coverage, and facilitate the uniform deployment of
     technological innovations as the Company manages its future upgrade
     paths.
 
  .  Systems Integration Capabilities. The Company believes that its ability
     to offer computer outsourcing and systems integration services,
     particularly services relating to allowing a customer's legacy systems
     to be accessed with web browsers, will provide additional opportunities
     for selling the Company's products and services.
 
The Level 3 Network
 
   An important element of the Business Plan is the development of the Level 3
network, an international, end-to-end network optimized for IP technology.
Today, the Company is primarily offering its communications services using
local and intercity facilities that are leased from third parties. This enables
the Company to offer services during the construction of its own facilities.
Over time, the portion of the Company's network that is owned by the Company
will increase and the portion of the facilities leased will decrease. Over the
next three to five years, the Company's network is expected to encompass:
 
   .  an intercity network covering nearly 16,000 miles in North America;
 
   .  backbone facilities in 40 North American markets;
 
   .  leased backbone facilities in 10 additional North American markets;
 
   .  an intercity network covering approximately 3,500 miles across Europe;
 
                                      S-35
<PAGE>
 
   .  leased or owned backbone facilities in 13 European and 8 Pacific Rim
      markets; and
 
   .  transoceanic capacity.
 
See "Risk Factors--Difficulties in constructing our network could increase its
estimated costs and delay its scheduled completion."
 
   Intercity Networks. The Company's nearly 16,000 mile fiber optic intercity
network in North America will consist of the following:
 
  .  Rights-of-way ("ROW") from a number of third parties including
     railroads, highway commissions and utilities. The Company is procuring
     these rights from sources which maximize the security and quality of the
     Company's installed network. As of February 2, 1999, the Company had use
     of approximately 14,400 miles of ROW which will satisfy approximately
     93% of the ROW requirements for the North American intercity network. It
     has obtained these rights pursuant to agreements with Union Pacific
     Railroad Company, Burlington Northern & Santa Fe Railroad Company,
     Canadian Pacific Railway Co., Norfolk Southern Corporation and others.
 
  .  Multiple conduits connecting local city networks in approximately 200
     North American cities, in 50 of which the Company expects to have city
     networks. In general, Level 3 will install groups of 10 conduits in its
     intercity network, but will install groups of up to 12 conduits in areas
     where it expects network demand to be stronger. The Company believes
     that the availability of spare conduit will allow it to deploy future
     technological innovations in optical networking components as well as
     providing Level 3 with the flexibility to offer conduit to other
     entities.
 
  .  Initial installation of optical fiber strands designed to accommodate
     dense wave division multiplexing transmission technology. This fiber
     allows deployment of equipment which transmits signals on 32 or more
     individual wavelengths of light per strand, thereby significantly
     increasing the capacity of the Company's network relative to older
     networks which generally use optical fiber strands that transmit fewer
     wavelengths of light per strand. In addition, the Company believes that
     the installation of newer optical fibers will allow a combination of
     greater wavelengths of light per strand, higher digital transmission
     speeds and greater spacing of network electronics. The Company also
     believes that each new generation of optical fiber will allow increases
     in the performance of these aspects of the fiber and will result in
     lower unit costs.
 
  .  High speed SONET transmission equipment employing self-healing
     protection switching and designed for high quality and reliable
     transmission.
 
  .  A design that maximizes the use of open, non-proprietary hardware and
     software interfaces to allow less costly upgrades as hardware and
     software technology improves.
 
   To support the launch of its services in the third quarter of 1998, the
Company has leased intercity capacity from two providers, connecting the first
15 Level 3 North American markets. This leased capacity will be displaced over
time by Level 3's North American intercity network.
 
   On July 20, 1998, Level 3 entered into a network construction cost-sharing
agreement with INTERNEXT, LLC, a subsidiary of NEXTLINK Communications, Inc.
The agreement, which is valued at $700 million, calls for INTERNEXT to acquire
the right to use 24 fibers and certain associated facilities installed along
the entire route of Level 3's North American intercity network in the United
States. INTERNEXT will pay Level 3 as segments of the intercity network are
completed which will reduce the overall cost of the network to the Company. The
network as provided to INTERNEXT will not include the necessary electronics
that allow the fiber to carry communications transmissions. Also, under the
terms of the agreement, INTERNEXT has the right to an additional conduit for
its exclusive use and to share costs and capacity in certain future fiber cable
installations in Level 3 conduits.

   The following diagram depicts the currently planned North American intercity
network when fully constructed:
 
                                     [MAP]

   The North American intercity network is expected to be completed during the
first quarter of 2001. Deployment of the North American intercity network will
be accomplished through simultaneous construction efforts in multiple
locations, with different portions being completed at different times. As of
December 31, 1998, the Company has completed 410 route miles of the intercity
network and has an additional 850 route miles under construction.
 
   In Europe, the Company is deploying an approximately 3,500 mile fiber optic
intercity network with characteristics similar to those of the North American
intercity network. As in North America, the Company will provide initial
service in Europe over a leased line and dark fiber network that will be
displaced over time by the intercity network owned by the Company. The Company
has recently begun development of the first approximately 1,750 mile portion of
the European intercity network, with completion expected by the end of the
third quarter of 2000. In the Pacific Rim, the Company currently intends to
provide service over a leased line intercity network and long term leases of
submarine cable capacity.
 
   In 1998, the Company entered into transoceanic capacity agreements for three
systems which will link Level 3's North American, European and Pacific Rim
intercity networks. One agreement provides for Level 3's participation in the
construction of an undersea cable system that will connect Japan and the United
States by mid-year 2000. The remaining two agreements were entered into by the
Company for trans-Atlantic capacity.
 
   Local Market Infrastructure. The Company's local facilities include fiber
optic networks, in a SONET ring configuration, connecting Level 3's intercity
network gateway sites to ILEC and CLEC central offices, long distance carrier
POPs, buildings housing communication-intensive end users and Internet peering
and transit facilities.
 
   The Company has secured approximately 1.25 million square feet of space for
its gateway facilities as of January 1999 and has completed the buildout of
approximately 825,000 square feet of this space. The Company's gateway
facilities are being designed to house local sales staff, operational staff,
the Company's transmission and IP routing/switching facilities and technical
space to accommodate colocation of equipment by high-volume Level 3 customers,
such as ISPs, in an environmentally controlled, secure site with direct access
to the Level 3 network through dual, fault tolerant connections. The Company
has gateway facilities, which vary in size, in New York City, Washington, D.C.,
Philadelphia, Atlanta, Boston, Dallas, Houston, Chicago, Detroit, Denver,
Seattle, San Francisco, San Jose, Los Angeles, San Diego, Manchester, New
Hampshire and Providence, Rhode Island. The Company is offering a limited set
of services (including
 
                                      S-37
<PAGE>
 
private line, colocation services, Internet access and managed modem) at its
gateway sites in these cities. The availability of these services varies by
location.
 
   As of December 31, 1998, local network development was underway in 25 U.S.
cities. In January 1999, the Company's initial local fiber loops became
operational in three cities--Dallas, Denver and Seattle--with construction of
loops in five additional cities expected to be completed in the second quarter
of 1999.
 
   As of February 1, 1999, the Company had 107 approved ILEC colocation
applications in 27 cities and completed construction in 38 of these central
offices. As of February 1, 1999, the Company had entered into interconnection
agreements with RBOCs covering 22 cities.
 
   The Company has negotiated master leases with several CLECs and ILECs to
obtain leased capacity from those providers so that the Company can provide its
clients with local transmission capabilities before its own local networks are
complete and in locations not directly accessed by the Company's owned
facilities.
 
   The launches of services in London and Frankfurt followed the Company's
acquisitions of BusinessNet Limited, a leading UK ISP, in January 1999 and
miknet Internet Based Services GmbH, a leading German ISP, in September 1998.
The Company launched its international gateway in London in January 1999. The
75,000 square foot office and operations facility will be the hub of European
operations and will house the operational center and network equipment, along
with additional space for expansion and colocation services. The Company plans
to offer services in and between Paris, Amsterdam and Frankfurt in 1999 and one
additional European city, also in 1999.
 
Communication and Information Services
 
   In connection with the Business Plan, the Company is substantially
increasing the emphasis it places on and the resources devoted to its
communications and information services business. The Company intends to build
on the strengths of its information services business and the benefits of the
Level 3 network to offer a broad range of other services to business and other
end users.
 
   Level 3 currently offers, through its subsidiary PKSIS, computer operations
outsourcing and systems integration services to customers located throughout
the United States as well as abroad. The Company's systems integration services
help customers define, develop and implement cost-effective information
services. The computer outsourcing services offered by the Company include
networking and computing services necessary for older mainframe-based systems
and newer client/server-based systems. The Company provides its outsourcing
services to clients that want to focus their resources on core businesses,
rather than expend capital and incur overhead costs to operate their own
computing environments. Level 3 believes that it is able to utilize its
expertise and experience, as well as operating efficiencies, to provide its
outsourcing customers with levels of service equal to or better than those
achievable by the customers themselves, while at the same time reducing the
customers' cost for such services. This service is particularly useful for
those customers moving from older computing platforms to more modern
client/server networks.
 
   The Company offers reengineering services that allow companies to convert
older legacy software systems to modern networked computing systems, with a
focus on reengineering software to enable older software application and data
repositories to be accessed by web browsers over the Internet or over private
or limited access IP networks. Through its Suite 2000SM line of services, the
Company provides customers with a multi-phased service for converting programs
and applications so that date-related information is accurately processed and
stored before and after the year 2000. The Company also provides customers with
a combination of workbench tools and methodologies that provide a complete
strategy for converting mainframe-based application systems to client/server
architecture, while at the same time ensuring Year 2000 compliance. See "Risk
Factors--Our Year 2000 compliance efforts may not succeed, and PKS Systems may
have liability from its Year 2000 customer projects."

<PAGE>
 
   As the Business Plan is being implemented, the Company is beginning to offer
a comprehensive range of communications services, including the following:
 
  .  Private Line and Special Access. Private line and special access
     services are established as a permanent physical connection between
     locations for the exclusive use of the customer. The Company is offering
     the following types of special access and private line services:
 
    .  Private Line. This type of link is a dedicated line connecting two
       end-user locations for voice and data applications, including ISPs.
 
    .  Carrier-to-Carrier Special Access. This type of link connects
       carriers (long distance providers, wireless providers, ILECs and
       CLECs) to other carriers.
 
    .  End-user to Long Distance Provider Special Access. This type of link
       connects an end-user, such as a large business, with the local POP
       of its chosen long distance provider.
 
     The Company is currently offering its local special access and private
     line services with available transmission speeds from T1 to OC3 and OC48
     and its long distance services will be offered at speeds from T1 to OC3
     and OC48. The Company is initially marketing its special access and
     private line services to ISPs, resellers and medium to large corporate
     customers.
 
  .  Colocation. The Company is offering its customers and other service
     providers the ability to locate their communications and networking
     equipment at Level 3's gateway sites in a safe and secure technical
     operating environment. The demand for these colocation services has
     increased as companies expand into geographic areas in which they do not
     have appropriate space or technical personnel to support their equipment
     and operations. At its operational colocation sites, the Company is
     offering customers AC/DC power, optional UPS power, emergency back-up
     generator power, HVAC, fire protection and security. Level 3 is also
     offering high-speed, reliable connectivity to the Level 3 leased network
     and other networks, including both local and wide area networks, the
     PSTN and Internet. These sites are being monitored and maintained 24
     hours a day, seven days a week.
 
     Level 3 is offering customers, including ISPs, the opportunity to
     colocate their web-server computers at the Company's larger gateway
     sites, enabling them to take advantage of the marketing, customer
     service, internal company information ("intranets") and other benefits
     offered by such web presence. By colocating its web-server in a Level 3
     facility, a customer has the ability to deploy a high-quality, high-
     reliability Internet presence without investing capital in data center
     space, multiple high-speed connections or other capital intensive
     infrastructure. Although the customer is responsible for maintaining the
     content and performance of its server, the Company's technicians will be
     available to monitor basic server operation. The Company will also offer
     redundant infrastructure consisting of multiple routers and connections
     to Internet backbones and is also offering IP services such as e-mail,
     news feeds and Domain Name Services.
 
  .  Internet Access. The Company is beginning to offer Internet access to
     business customers, other carriers and ISPs. These services include
     high-capacity Internet connections ranging from T1 to OC3 transmission
     speeds. The Company has peering arrangements with approximately 60 ISPs
     and is currently purchasing transit from two major ISPs.
 
  .  Managed Modem. The Company is offering to its customers an outsourced,
     turn-key infrastructure solution for the management of dial up access to
     either the public Internet or a corporate data network that may include
     access to the public Internet ("Managed Modem"). While ISPs are provided
     a fully managed dial-up network infrastructure for access to the public
     Internet, corporate customers that purchase Managed Modem services
     receive connectivity for remote users to support data applications such
     as telecommuting, e-mail retrieval, and client/server applications. For
     Managed Modem customers, Level 3 arranges for the provision of local
     network coverage, dedicated local telephone numbers (which the Managed
     Modem customer distributes to its customers in the case of an ISP or to
     its employees in the case of a corporate customer), racks and modems as
     well as dedicated connectivity from the customers location to the Level
     3 gateway facility. Level 3 also provides monitoring of this
     infrastructure 24 hours a day, seven days a week. By providing a turn-
     key
 
                                      S-39
<PAGE>
 
     infrastructure modem solution, Level 3 believes that this product allows
     its customers to save both capital and operating costs.
 
  .  Voice and Fax. The Company seeks to offer voice and fax services,
     including both real-time voice and fax transmission services, which are
     accessed using existing telephone and fax equipment and existing dialing
     procedures. The Company expects that these services will be offered at a
     quality level equal to that of the PSTN.
 
  .  Special Services. The Company is offering dark fiber and conduit along
     its local and intercity networks on a long term lease basis. Dark fiber
     is the term that is used to describe fiber optic strands that are not
     connected to transmission equipment. A customer can obtain dark fiber
     and/or conduit in any combination of three ways: (1) segment by segment,
     (2) full ring or (3) the entire Level 3 network. Level 3 offers
     colocation space in its gateway and intercity retransmission facilities
     to these customers for the placement of their transmission electronics.
     Although Level 3 will not be responsible for the management of the
     customer's transmission electronics, Level 3 is contemplating providing
     installation and maintenance services for this equipment on a fee for
     service basis.
 
Distribution Strategy
 
   The Company's distribution strategy is to utilize a direct sales force as
well as alternative distribution channels. Through the combination of a direct
sales force and alternative distribution channels, the Company believes that
it will be able to more rapidly access markets and increase revenue-producing
traffic on its network. To implement its distribution strategy, the Company is
developing an in-house direct sales force and has identified a variety of
possible alternative distribution channels.
 
   The Company uses its direct sales force to market its available products
and services directly to large communications-intensive businesses. In
addition, the direct sales force targets national and international accounts.
These communications-intensive customers would typically be connected directly
to the Level 3 leased network using unswitched, dedicated facilities.
 
   As part of its distribution strategy, the Company has identified several
potential alternative distribution channels. These include agents, resellers
and wholesalers.
 
  .  Agents are independent organizations that sell Level 3's products and
     services under the Level 3 brand name to end-users in exchange for
     revenue based commissions. The Company intends to identify agents that
     generally would be focused on specific market segments (such as small
     and medium sized businesses) and have existing customer bases. Sales
     through this alternative distribution channel require Level 3 to provide
     the same type of services that would be provided in the case of sales
     through its own direct sales force such as order fulfillment, billing
     and collections, customer care and direct sales management.
 
  .  Resellers are independent companies that purchase Level 3's products and
     services and then "repackage" these services for sale to their customers
     under their own brand name. Resellers generally require access to
     certain of the Company's business operating systems in connection with
     the sale of the Company's services to the resellers' customers. Sales
     through this distribution channel generally do not require Level 3 to
     provide order fulfillment, billing and collection and customer care.
 
  .  Wholesalers are independent companies that purchase from the Company
     unbundled network and service capabilities in large quantities in order
     to market their own products and services under a brand name other than
     Level 3. Wholesalers have minimal dependence on the Company's business
     support systems in connection with the sale of services to their
     customers.
 
   The Company anticipates that participants in its alternative distribution
channels will sell services directly to medium and small businesses and
consumers. The Company expects these medium and small businesses and consumers
to access the Level 3 network by using local switched services that are
provided by CLECs or
 
                                     S-40
<PAGE>
 
ILECs or by utilizing newly emerging alternatives including various DSL modem
technologies, cable modems and wireless access technologies.
 
Business Support System
 
   In order to pursue its direct sales and alternative distribution strategies,
the Company is developing a set of integrated software applications designed to
automate the Company's operational processes. Through the development of a
robust, scalable business support system, the Company believes that it has the
opportunity to develop a competitive advantage relative to traditional
telecommunications companies. Whereas traditional telecommunications companies
operate extensive legacy business support systems with compartmentalized
architectures that limit their ability to scale rapidly and introduce enhanced
services and features, the Company has developed a business support system
architecture intended to maximize both reliability and scalability. See "Risk
Factors--Our Business Plan requires the development of effective business
support systems to implement customer orders and to provide and bill for
services."
 
   Key design aspects of the business support system development program are:
 
  .  integrated modular applications to allow the Company to upgrade specific
     applications as new products are available;
 
  .  a scalable architecture that allows certain functions that would
     otherwise have to be performed by Level 3 employees to be performed by
     the Company's alternative distribution channel participants;
 
  .  phased completion of software releases designed to allow the Company to
     test functionality on an incremental basis;
 
  .  ""web-enabled" applications so that on-line access to all order entry,
     network operations, billing, and customer care functions is available to
     all authorized users, including Level 3's customers and resellers;
 
  .  use of a three-tiered, client/server architecture that is designed to
     separate data and applications, and is expected to enable continued
     improvement of software functionality at minimum cost; and
 
  .  maximum use of pre-developed or "shrink wrapped" applications, which
     will interface to Level 3's enterprise resource planning suites.
 
   The first three releases of the business support system have been delivered
and contain functionality necessary to support the set of services presently
offered. See "--Communication and Information Services."
 
Interconnection and Peering
 
   As a result of the Telecom Act, properly certificated companies may, as a
matter of law, interconnect with ILECs on terms designed to help ensure
economic, technical and administrative equality between the interconnected
parties. The Telecom Act provides, among other things, that ILECs must offer
competitors the services and facilities necessary to offer local switched
services. See "--Regulation."
 
   As of February 1, 1999, the Company had entered into interconnection
agreements covering 22 cities. The Company may be required to negotiate new or
renegotiate existing interconnection agreements as Level 3 expands its
operations in current and additional markets in the future.
 
   Peering agreements between the Company and ISPs are necessary in order for
the Company to exchange traffic with those ISPs without having to pay transit
costs. The Company has peering arrangements with approximately 60 ISPs and is
currently purchasing transit from two major ISPs. The basis on which the large
national ISPs make peering available or impose settlement charges is evolving
as the provision of Internet access and related services has expanded.
Recently, companies that have previously offered peering have cut back or
eliminated peering relationships and are establishing new, more restrictive
criteria for peering. In order to maintain certain of its peering
relationships, Level 3 will have to meet these more restrictive criteria. See
"Risk Factors--Burdensome peering and transit arrangements result in higher
costs."
 
                                      S-41
<PAGE>
 
Employee Recruiting and Retention
 
   As of December 31, 1998, Level 3 had 1,225 employees in the communications
portion of its business and PKSIS had approximately 959 employees, for a total
of 2,184 employees. The Company believes that its ability to implement the
Business Plan will depend in large part on its ability to attract and retain
substantial numbers of additional qualified employees. In order to attract and
retain highly qualified employees, the Company believes that it is important to
provide (i) a work environment that encourages each individual to perform to
his or her potential, (ii) a work environment that facilitates cooperation
towards shared goals and (iii) a compensation program designed to attract the
kinds of individuals the Company seeks and to align employees' interests with
the Company's. The Company believes the Business Plan and its announced
relocation to new facilities, currently being constructed in the Denver
metropolitan area, help provide such a work environment. With respect to
compensation programs, while the Company believes financial rewards alone are
not sufficient to attract and retain qualified employees, the Company believes
a properly designed compensation program is a necessary component of employee
recruitment and retention. In this regard the Company's philosophy is to pay
annual cash compensation which, if the Company's annual goals are met, is
moderately greater than the cash compensation paid by competitors. The
Company's non-cash benefit programs (including medical and health insurance,
life insurance, disability insurance, etc.) are designed to be comparable to
those offered by its competitors. See "Risk Factors--We may be unable to hire
and retain sufficient qualified personnel; the loss of any of our key executive
officers could adversely affect us."
 
   The Company believes that the qualified candidates it seeks place particular
emphasis on equity-based long term incentive ("LTI") programs. The Company
currently has two complementary programs: (i) the equity-based "Shareworks"
program, which helps ensure that all employees have an ownership interest in
the Company and are encouraged to invest risk capital in the Company's stock;
and (ii) an innovative Outperform Stock Option ("OSO") program applicable to
the Company's middle and senior management. The Shareworks program currently
enables employees to contribute up to 7% of their compensation toward the
purchase of restricted common stock. If an employee remains employed by the
Company for three years from the date of purchase, the shares will vest and be
matched by the Company with a grant of an equal number of shares of its common
stock. The Shareworks program also provides that, subject to satisfactory
Company performance, the Company's employees will be eligible annually for
grants by the Company of its restricted common stock of up to 3% of the
employees' compensation, which shares will vest three years from the grant
date.
 
   With respect to middle and senior management, the Company has adopted the
OSO program, which differs from LTI programs generally adopted by the Company's
competitors that make employees eligible for conventional non-qualified stock
options ("NQSOs"). While widely adopted, the Company believes such NQSO
programs reward eligible employees when company stock price performance is
inferior to investments of similar risks, dilute public stockholders in a
manner not directly proportional to performance and fail to provide a preferred
return on stockholders' invested capital over the return to option holders. The
Company believes that the OSO program is superior to an NQSO-based program with
respect to these issues while, at the same time, providing eligible employees a
success-based reward balancing the associated risk.
 
   The OSO program was designed by the Company so that its stockholders receive
a market related return on their investment before OSO holders receive any
return on their options. The Company believes that the OSO program aligns
directly management's and stockholders' interests by basing stock option value
on the Company's ability to outperform the market in general, as measured by
the S&P 500 Index. The value received for options under the OSO plan is based
on a formula involving a multiplier related to how much our common stock
outperforms the S&P 500 Index. Participants in the OSO program do not realize
any value from options unless our common stock price outperforms the S&P 500
Index. To the extent that our common stock outperforms the S&P 500, the value
of OSOs to an option holder may exceed the value of NQSOs.
 
   Subsequent to the split-off, the Company adopted the recognition provisions
of SFAS No. 123. Under SFAS No. 123, the fair value of an OSO (as computed in
accordance with accepted option valuation models) on the date of grant is
amortized over the vesting period of the OSO. The recognition provisions of
SFAS No.
 
                                      S-42
<PAGE>
 
123 are applied prospectively upon adoption. As a result, they are applied to
all stock awards granted in the year of adoption and are not applied to awards
granted in previous years unless those awards are modified or settled in cash
after adoption of the recognition provisions. While the Company has not yet
determined the total effect of adopting the recognition provisions of SFAS No.
123, the adoption resulted in non-cash charges to operations in 1998 of
approximately $39 million and will result in OSO program non-cash charges to
operations for future periods that the Company believes will also be material.
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.
 
Competition
 
   The communications and information services industry is highly competitive.
Many of the Company's existing and potential competitors in the communications
and information services industry have financial, personnel, marketing and
other resources significantly greater than those of the Company, as well as
other competitive advantages including existing customer bases. Increased
consolidation and strategic alliances in the industry resulting from the
Telecom Act, the opening of the U.S. market to foreign carriers, technological
advances and further deregulation could give rise to significant new
competitors to the Company.
 
   In the special access and private line services market, the Company's
primary competitors will be IXCs, ILECs and CLECs. In the market for the
colocation of CLECs, the Company will compete with ILECs and CLECs. Most of
these competitors have a significant base of customers for whom they are
currently providing colocation services. Due to the high costs to CLECs of
switching colocation sites, the Company may have a competitive disadvantage
relative to these competitors. The market for the colocation of web-servers is
extremely competitive. In this market, the Company competes with ISPs and many
others, including IXCs, companies that provide only web hosting/IP colocation
services and a number of companies in the computer industry.
 
   For voice and fax services, the Company will compete primarily with national
and regional network providers. There are currently three principal facilities-
based long distance fiber optic networks (AT&T, Sprint and MCI WorldCom), as
well as numerous ILEC and CLEC networks. Others, including Qwest, IXC and
Williams, are building additional networks that employ advanced technology
similar to that of the Level 3 Network and offer significantly more capacity to
the marketplace. The additional capacity that is expected to become available
in the next several years may cause significant decreases in the prices for
services. The ability of the Company to compete effectively in this market will
depend upon its ability to maintain high quality services at prices equal to or
below those charged by its competitors. In the long distance market, the
Company's primary competitors will include AT&T, MCI WorldCom and Sprint, all
of whom have extensive experience in the long distance market. In addition, the
Telecom Act will allow the RBOCs and others to enter the long distance market.
In local markets the Company will compete with ILECs and CLECs, many of whom
have extensive experience in the local market. While the Company believes that
IP technology will prove to be a viable technology for the transmission of
voice and fax services, technology is not yet in place that will enable the
Company to provide voice and fax services at an acceptable level of quality.
There can be no assurance that the Company can develop or acquire such
technology. See "Risk Factors--A failure to develop or acquire satisfactory
voice or fax technology for Internet Protocol networks could adversely affect
our business."
 
   The communications and information services industry is subject to rapid and
significant changes in technology. For instance, recent technological advances
permit substantial increases in transmission capacity of both new and existing
fiber, and the introduction of new products or emergence of new technologies
may reduce the cost or increase the supply of certain services similar to those
which the Company plans on providing. Accordingly, in the future the Company's
most significant competitors may be new entrants to the communications and
information services industry, which are not burdened by an installed base of
outmoded equipment.

Regulation
 
   The Company's communications services business will be subject to varying
degrees of federal, state, local and international regulation.
 
 Federal Regulation
 
   The FCC regulates interstate and international telecommunications services.
The FCC imposes extensive regulations on common carriers such as ILECs that
have some degree of market power. The FCC imposes less regulation on common
carriers without market power, such as the Company. The FCC permits these
nondominant carriers to provide domestic interstate services (including long
distance and access services) without prior authorization; but it requires
carriers to receive an authorization to construct and operate
telecommunications facilities, and to provide or resell telecommunications
services, between the United States and international points. The Company has
obtained FCC authorization to provide international services on a facilities
and resale basis. The Company will be required to file tariffs for its
interstate and international long distance services with the FCC before
commencing operations.
 
   Under the Telecom Act, any entity, including cable television companies, and
electric and gas utilities, may enter any telecommunications market, subject to
reasonable state regulation of safety, quality and consumer protection. Because
implementation of the Telecom Act is subject to numerous federal and state
policy rulemaking proceedings and judicial review, there is still uncertainty
as to what impact it will have on the Company. The Telecom Act is intended to
increase competition. The Telecom Act opens the local services market by
requiring ILECs to permit interconnection to their networks and establishing
ILEC obligations with respect to:
 
  .  Reciprocal Compensation. Requires all ILECs and CLECs to complete calls
     originated by competing carriers under reciprocal arrangements at prices
     based on a reasonable approximation of incremental cost or through
     mutual exchange of traffic without explicit payment.
 
  .  Resale. Requires all ILECs and CLECs to permit resale of their
     telecommunications services without unreasonable restrictions or
     conditions. In addition, ILECs are required to offer wholesale versions
     of all retail services to other telecommunications carriers for resale
     at discounted rates, based on the costs avoided by the ILEC in the
     wholesale offering.
 
  .  Interconnection. Requires all ILECs and CLECs to permit their
     competitors to interconnect with their facilities. Requires all ILECs to
     permit interconnection at any technically feasible point within their
     networks, on nondiscriminatory terms, at prices based on cost (which may
     include a reasonable profit). At the option of the carrier seeking
     interconnection, colocation of the requesting carrier's equipment in an
     ILEC's premises must be offered, except where the ILEC can demonstrate
     space limitations or other technical impediments to colocation.
 
  .  Unbundled Access. Requires all ILECs to provide nondiscriminatory access
     to unbundled network elements (including network facilities, equipment,
     features, functions, and capabilities) at any technically feasible point
     within their networks, on nondiscriminatory terms, at prices based on
     cost (which may include a reasonable profit).
 
  .  Number Portability. Requires all ILECs and CLECs to permit users of
     telecommunications services to retain existing telephone numbers without
     impairment of quality, reliability or convenience when switching from
     one telecommunications carrier to another.
 
  .  Dialing Parity. Requires all ILECs and CLECs to provide "1+" equal
     access to competing providers of telephone exchange service and toll
     service, and to provide nondiscriminatory access to telephone numbers,
     operator services, directory assistance, and directory listing, with no
     unreasonable dialing delays.
 
  .  Access to Rights-of-Way. Requires all ILECs and CLECs to permit
     competing carriers access to poles, ducts, conduits and rights-of-way at
     regulated prices.
 
 
                                      S-44

   ILECs are required to negotiate in good faith with carriers requesting any
or all of the above arrangements. If the negotiating carriers cannot reach
agreement within a prescribed time, either carrier may request binding
arbitration of the disputed issues by the state regulatory commission. Where an
agreement has not been reached, ILECs remain subject to interconnection
obligations established by the FCC and state telecommunication regulatory
commissions.
 
   In August 1996, the FCC released a decision (the "Interconnection Decision")
establishing rules implementing the above-listed requirements and providing
guidelines for review of interconnection agreements by state public utility
commissions. The United States Court of Appeals for the Eighth Circuit (the
"Eighth Circuit") vacated certain portions of the Interconnection Decision. On
January 25, 1999, the Supreme Court reversed the Eighth Circuit with respect to
the FCC's jurisdiction to issue regulations governing local interconnection
pricing (including regulations governing reciprocal compensation). The Supreme
Court also found that the FCC had authority to promulgate a "pick and choose"
rule and upheld most of the FCC's rules governing access to unbundled network
elements. The Supreme Court, however, remanded to the FCC the standard by which
the FCC identified the network elements that must be made available on an
unbundled basis.
 
   The Eighth Circuit decisions and their recent reversal by the Supreme Court
continue to cause uncertainty about the rules governing the pricing, terms and
conditions of interconnection agreements. The Supreme Court's action in
particular may require or trigger the renegotiation of existing agreements.
Although state public utilities commissions have continued to conduct
arbitrations, and to implement and enforce interconnection agreements during
the pendency of the Eighth Circuit proceedings, the Supreme Court's recent
ruling and further proceedings on remand (either at the Eighth Circuit or the
FCC) may affect the scope of state commissions' authority to conduct such
proceedings or to implement or enforce interconnection agreements. They could
also result in new or additional rules being promulgated by the FCC. Given the
general uncertainty surrounding the effect of the Eighth Circuit decisions and
the recent decision of the Supreme Court reversing them, there can be no
assurance that the Company will be able to continue to obtain or enforce
interconnection terms that are acceptable to it or that are consistent with its
business plans.
 
   The Telecom Act also codifies the ILECs' equal access and nondiscrimination
obligations and preempts inconsistent state regulation. The Telecom Act
contains special provisions that modify previous court decrees that prevented
RBOCs from providing long distance services and engaging in telecommunications
equipment manufacturing. These provisions permit a RBOC to enter the long
distance market in its traditional service area if it satisfies several
procedural and substantive requirements, including obtaining FCC approval upon
a showing that the RBOC has entered into interconnection agreements (or, under
some circumstances, has offered to enter into such agreements) in those states
in which it seeks long distance relief, the interconnection agreements satisfy
a 14-point "checklist" of competitive requirements, and the FCC is satisfied
that the RBOC's entry into long distance markets is in the public interest. To
date, several petitions by RBOCs for such entry have been denied by the FCC,
and none have been granted. The Telecom Act permitted the RBOCs to enter the
out-of-region long distance market immediately upon its enactment.
 
   In October 1996, the FCC adopted an order in which it eliminated the
requirement that non-dominant carriers such as the Company maintain tariffs on
file with the FCC for domestic interstate services. This order applies to all
non-dominant interstate carriers, including AT&T. The order does not apply to
the RBOCs or other local exchange providers. The FCC order was issued pursuant
to authority granted to the FCC in the Telecom Act to "forbear" from regulating
any telecommunications services provider if the FCC determines that the public
interest will be served. On February 13, 1997, the United States Court of
Appeals for the District of Columbia Circuit stayed the implementation of the
FCC order pending its review of the order on the merits. Currently, that
temporary stay remains in effect.
 
   If the stay is lifted and the FCC order becomes effective,
telecommunications carriers such as the Company will no longer be able to rely
on the filing of tariffs with the FCC as a means of providing notice to
customers of prices, terms and conditions on which they offer their interstate
services. The obligation to
 
                                      S-45
<PAGE>
 
provide non-discriminatory, just and reasonable prices remains unchanged under
the Communications Act of 1934. While tariffs provided a means of providing
notice of prices, terms and conditions, the Company intends to rely primarily
on its sales force and direct marketing to provide such information to its
customers.
 
   The Company's costs of providing long distance services, as well as its
revenues from providing local services, will both be affected by changes in the
"access charge" rates imposed by ILECs on long distance carriers for
origination and termination of calls over local facilities. In two orders
released on December 24, 1996, and May 16, 1997, the FCC made major changes in
the interstate access charge structure. In the December 24th order, the FCC
removed restrictions on ILECs' ability to lower access prices and relaxed the
regulation of new switched access services in those markets where there are
other providers of access services. If this increased pricing flexibility is
not effectively monitored by federal regulators, it could have a material
adverse effect on the Company's ability to price its interstate access services
competitively. The May 16th order substantially increased the amounts that
ILECs subject to the FCC's price cap rules ("price cap LECs") recover through
monthly flat-rate charges and substantially decreased the amounts that these
LECs recover through traffic sensitive (per-minute) access charges. In the May
16th order, the FCC also announced its plan to bring interstate access rate
levels more in line with cost. The plan will include rules that are expected to
be established sometime in 1999 that may grant price cap LECs increased pricing
flexibility upon demonstrations of increased competition (or potential
competition) in relevant markets. The manner in which the FCC implements this
approach to lowering access charge levels could have a material effect on the
Company's revenues and costs. Several parties have appealed the May 16th order.
Those appeals were consolidated and transferred to the Eighth Circuit. On
August 19, 1998, the Eighth Circuit upheld the FCC's access charge reform
rules.
 
   Beginning in June 1997, every RBOC advised CLECs that they did not consider
calls in the same local calling area from their customers to CLEC customers,
who are ISPs, to be local calls under the interconnection agreements between
the RBOCs and the CLECs. The RBOCs claim that these calls are exchange access
calls for which exchange access charges would be owed. The RBOCs claimed,
however, that the FCC exempted these calls from access charges so that no
compensation is owed to the CLECs for transporting and terminating such calls.
As a result, the RBOCs threatened to withhold, and in many cases did withhold,
reciprocal compensation for the transport and termination of such calls. To
date, twenty-nine state commissions have ruled on this issue in the context of
state commission arbitration proceedings or enforcement proceedings. In every
state, to date, the state commission has determined that reciprocal
compensation is owed for such calls. Several of these cases are presently on
appeal. Reviewing courts have upheld the state commissions in the four
decisions rendered to date on appeal. Appeals from these decisions are pending
in the Fifth, Seventh and Ninth U.S. Circuit Courts of Appeal. The issue is
also pending review before the FCC, which in a related case determined direct
links to ISPs involved interstate and not local traffic. If the FCC determines
that dial-up calls to ISPs are interstate, ILECs will seek to overturn the
state commission decisions. The Company cannot predict the outcome of these
appeals, or of additional pending cases. If these calls were to be determined
not to be local calls and not subject to access charges, it could have an
adverse effect on the Company.
 
   The FCC has to date treated ISPs as "enhanced service providers," exempt
from federal and state regulations governing common carriers, including the
obligation to pay access charges and contribute to the universal service fund.
Nevertheless, regulations governing disclosure of confidential communications,
copyright, excise tax, and other requirements may apply to the Company's
provision of Internet access services. The Company cannot predict the
likelihood that state, federal or foreign governments will impose additional
regulation on the Company's Internet business, nor can it predict the impact
that future regulation will have on the Company's operations.
 
   In December 1996, the FCC initiated a Notice of Inquiry regarding whether to
impose regulations or surcharges upon providers of Internet access and
information services (the "Internet NOI"). The Internet NOI sought public
comment upon whether to impose or continue to forebear from regulation of
Internet and other packet-switched network service providers. The Internet NOI
specifically identifies Internet telephony as a subject for FCC consideration.
On April 10, 1998, the FCC issued a Report to Congress on its implementation
 
                                      S-46
<PAGE>
 
of the universal service provisions of the Telecom Act. In that Report, the FCC
stated, among other things, that the provision of transmission capacity to ISPs
constitutes the provision of telecommunications and is, therefore, subject to
common carrier regulations. The FCC indicated that it would reexamine its
policy of not requiring an ISP to contribute to the universal service
mechanisms when the ISP provides its own transmission facilities and engages in
data transport over those facilities in order to provide an information
service. Any such contribution by a facilities-based ISP would be related to
the ISP's provision of the underlying telecommunications services. In the
Report, the FCC also indicated that it would examine the question of whether
certain forms of "phone-to-phone IP telephony" are information services or
telecommunications services. It noted that the FCC did not have an adequate
record on which to make any definitive pronouncements on that issue at this
time, but that the record the FCC had reviewed suggests that certain forms of
phone-to-phone IP telephony appear to have similar functionality to non-IP
telecommunications services and lack the characteristics that would render them
information services. If the FCC were to determine that certain IP telephony
services are subject to FCC regulations as telecommunications services, the FCC
noted it may find it reasonable that the ISPs pay access charges and make
universal service contributions similar to non-IP-based telecommunications
service providers. The FCC also noted that other forms of IP telephony appear
to be information services. The Company cannot predict the outcome of these
proceedings or other FCC proceedings that may effect the Company's operations
or impose additional requirements, or regulations or charges upon the Company's
provision of Internet access services.
 
   On May 8, 1997, the FCC issued an order establishing a significantly
expanded federal universal service subsidy regime. For example, the FCC
established new universal service funds to support telecommunications and
information services provided to qualifying schools and libraries (with an
annual cap of $2.25 billion) and to rural health care providers (with an annual
cap of $400 million). The FCC also expanded the federal subsidies for local
exchange telephone services provided to low-income consumers. Providers of
interstate telecommunications service, such as the Company, as well as certain
other entities, must pay for these programs. The Company's contribution to
these universal service funds will be based on its telecommunications service
end-user revenues. The extent to which the Company's services are viewed as
telecommunications services or as information services will impact the amount
of the Company's contributions, if any. As indicated in the preceding
paragraph, that issue has not been resolved. Currently, the FCC assesses such
payments on the basis of a provider's revenue for the previous year. Since the
Company had no significant telecommunications service revenues in 1997, it was
not liable for subsidy payments in any material amount during 1998. With
respect to subsequent years, however, the Company is currently unable to
quantify the amount of subsidy payments that it will be required to make and
the effect that these required payments will have on its financial condition
because of uncertainties concerning the size of the universal fund and
uncertainties concerning the classification of its services. In the May 8th
order, the FCC also announced that it will soon revise its rules for
subsidizing service provided to consumers in high cost areas, which may result
in further substantial increases in the overall cost of the subsidy program.
Several parties have appealed the May 8th order. Such appeals have been
consolidated and transferred to the Fifth Circuit Court of Appeals where they
are currently pending. The FCC's universal service program may also be altered
as a result of the agency's reconsideration of its policies, or by future
Congressional action.
 
 State Regulation
 
   The Telecom Act is intended to increase competition in the
telecommunications industry, especially in the local exchange market. With
respect to local services, ILECs are required to allow interconnection to their
networks and to provide unbundled access to network facilities, as well as a
number of other procompetitive measures. Because the implementation of the
Telecom Act is subject to numerous state rulemaking proceedings on these
issues, it is currently difficult to predict how quickly full competition for
local services, including local dial tone, will be introduced.
 
   State regulatory agencies have jurisdiction when Company facilities and
services are used to provide intrastate services. A portion of the Company's
traffic may be classified as intrastate and therefore subject to state
regulation. The Company expects that it will offer more intrastate services
(including intrastate switched
 
                                      S-47
<PAGE>
 
services) as its business and product lines expand and state regulations are
modified to allow increased local services competition. To provide intrastate
services, the Company generally must obtain a certificate of public convenience
and necessity from the state regulatory agency and comply with state
requirements for telecommunications utilities, including state tariffing
requirements. The Company currently is authorized to provide telecommunications
services in Arkansas (facilities-based IXC), California, Colorado, Connecticut,
Delaware, the District of Columbia, Florida, Georgia, Idaho, Illinois, Indiana,
Kentucky, Maryland, Massachusetts, Michigan, Missouri, Montana, Nebraska,
Nevada, New Hampshire, New Jersey, New York, Ohio, Oregon, Pennsylvania, Rhode
Island, South Carolina, Tennessee, Texas, Virginia, Washington, and Wyoming.
 
   The Company has pending applications for authority to provide
telecommunications service in Alabama, Arizona, Iowa, Kansas, Louisiana, Maine,
Minnesota, Mississippi, New Mexico, North Carolina, North Dakota, Oklahoma,
South Dakota, Vermont, West Virginia, Wisconsin, and Utah.
 
 Local Regulation
 
   The Company's networks will be subject to numerous local regulations such as
building codes and licensing. Such regulations vary on a city-by-city, county-
by-county and state-by-state basis. To install its own fiber optic transmission
facilities, the Company will need to obtain rights-of-way over private and
publicly owned land. There can be no assurance that rights-of-way that are not
already secured will be available to the Company on economically reasonable or
advantageous terms.
 
 Canadian Regulation
 
   The Canadian Radio-Television and Telecommunications Commission (the "CRTC")
generally regulates long distance telecommunications services in Canada.
Regulatory developments over the past several years have terminated the
historic monopolies of the regional telephone companies, bringing significant
competition to this industry for both domestic and international long distance
services, but also lessening regulation of domestic long distance companies.
Resellers, which, as well as facilities-based carriers, now have
interconnection rights, but which are not obligated to file tariffs, may not
only provide transborder services to the U.S. by reselling the services
provided by the regional companies and other entities but also may resell the
services of the monopoly international carrier, Teleglobe Canada ("Teleglobe"),
including offering international switched services provisioned over leased
lines. Although the CRTC formerly restricted the practice of "switched hubbing"
over leased lines through intermediate countries to a third country, the CRTC
recently lifted this restriction. The Teleglobe monopoly on international
services and submarine cable landing rights terminated as of October 1, 1998,
although the provision of Canadian international facilities-based services
remains restricted to "Canadian carriers" with majority ownership by Canadians.
Ownership of non-international facilities are limited to Canadian carriers but
the Company can own international submarine cables landing in Canada. The
Company cannot, under current or foreseen law, enter the Canadian market as a
provider of facilities-based domestic services. Pending proceedings address
issues such as the scope of contribution charges payable to the telephone
companies to offset some of the capital and operating costs of interconnection
as well as deregulation of the long distance services of the incumbent regional
telephone companies.
 
   While competition is now emerging in other Canadian telecommunications
market segments, the Company believes that the regional companies continue to
retain a substantial majority of the local and calling card markets. Beginning
in May 1997, the CRTC released a number of decisions opening to competition the
Canadian local telecommunications services market, which decisions were made
applicable in the territories of all Stentor member companies except SaskTel
(although Saskatchewan has subsequently allowed local service competition in
that province). As a result, networks operated by CLECs may now be
interconnected with the networks of the ILECs. Facilities-based ILECs are
subject to the same majority Canadian ownership "Canadian carrier" requirements
as facilities-based long distance carriers. CLECs have the same status as
ILECs, but they do not have universal service or customer tariff-filing
obligations. CLECs are subject to certain consumer
 
                                      S-48
<PAGE>
 
protection safeguards and other CRTC regulatory oversight requirements. CLECs
must file interconnection tariffs for services to interexchange service
providers and wireless service providers. Certain ILEC services must be
provided to CLECs on an unbundled basis and subject to mandatory pricing,
including central office codes, subscriber listings, and local loops in small
urban and rural areas. For a five-year period, certain other important CLEC
services must be provided on an unbundled basis at mandated prices. ILECs,
which, unlike CLECs, remained fully regulated, will not be subject to rate of
return regulation for an initial four-year period beginning May 1, 1997, but
their services must not be priced below cost. Interexchange contribution
payments are now pooled and distributed among ILECs and CLECs according to a
formula based on their respective proportions of residential lines, with no
explicit contribution payable from local business exchange or directory
revenues. CLECs must pay an annual telecommunications fee based on their
proportion of total CLEC operating revenues. All bundled and unbundled local
services (including residential lines and other bulk services) may now be
resold, but ILECs need not provide these services to resellers at wholesale
prices. Transmission facilities-based local and long distance carriers (but not
resellers) are entitled to colocate equipment in ILEC central offices pursuant
to terms and conditions of tariffs and intercarrier agreements. Certain local
competition issues are still to be resolved. The CRTC has ruled that resellers
cannot be classified as CLECs, and thus are not entitled to CLEC
interconnection terms and conditions.
 
The Company's Other Businesses
 
   The Company's other businesses include its investment in the C-TEC Companies
(as defined), coal mining, the SR91 Tollroad (as defined) and certain other
assets. The Company recently completed the sale of its interests in United
Infrastructure Company, CalEnergy and Kiewit Investment Management Corp.
 
 C-TEC Companies
 
   On September 30, 1997, C-TEC completed a tax-free restructuring, which
divided C-TEC into three public companies (the "C-TEC Companies"): C-TEC, which
changed its name to Commonwealth Telephone, RCN and Cable Michigan. The
Company's interests in the C-TEC Companies are held through a holding company
(the "C-TEC Holding Company"). The Company owns 90% of the common stock of the
C-TEC Holding Company, and preferred stock of the C-TEC Holding Company with a
liquidation value of approximately $467 million as of December 31, 1998. The
remaining 10% of the common stock of the C-TEC Holding Company is held by David
C. McCourt, a director of the Company who was formerly the Chairman of C-TEC.
In the event of a liquidation of the C-TEC Holding Company, the Company would
first receive the liquidation value of the preferred stock. Any excess of the
value of the C-TEC Holding Company above the liquidation value of the preferred
stock would be split according to the ownership of the common stock.
 
   Commonwealth Telephone. Commonwealth Telephone is a Pennsylvania public
utility providing local telephone service to a 19-county, 5,191 square mile
service territory in Pennsylvania. Commonwealth Telephone services
approximately 259,000 main access lines. Commonwealth Telephone also provides
network access and long distance services to IXCs. Commonwealth Telephone's
business customer base is diverse in size as well as industry, with very little
concentration. A subsidiary, Commonwealth Communications Inc. provides
telecommunications engineering and technical services to large corporate
clients, hospitals and universities in the northeastern United States. Another
subsidiary, Commonwealth Long Distance operates principally in Pennsylvania,
providing switched services and resale of several types of services, using the
networks of several long distance providers on a wholesale basis. As of
December 31, 1998, the C-TEC Holding Company owned approximately 48.3% of the
outstanding common stock of Commonwealth Telephone.
 
   On October 23, 1998, Commonwealth Telephone completed a rights offering of
3.7 million shares of its common stock. In the offering, Level 3 exercised all
rights it received and purchased approximately 1.8 million additional shares of
Commonwealth Telephone common stock for an aggregate subscription price of
$37.7 million.
 
 
                                      S-49
<PAGE>
 
   RCN. RCN is a full service provider of local, long distance, Internet and
cable television services primarily to residential users in densely populated
areas in the Northeast. RCN operates as a competitive telecommunications
service provider in New York City and Boston. RCN also owns cable television
operations in New York, New Jersey and Pennsylvania; a 40% interest in
Megacable, S.A. de C.V., Mexico's second largest cable television operator; and
has long distance operations (other than the operations in certain areas of
Pennsylvania). RCN is developing advanced fiber optic networks to provide a
wide range of telecommunications services, including local and long distance
telephone, video programming and data services (including high speed Internet
access), primarily to residential customers in selected markets in the Boston
to Washington, D.C. corridor. During the first quarter of 1998, RCN acquired
Ultranet Communications, Inc. and Erols Internet, Inc., two ISPs with
operations in the Boston to Washington, D.C. corridor. As of December 31, 1998,
the C-TEC Holding Company owned approximately 41.0% of the outstanding common
stock of RCN.
 
   Cable Michigan. Cable Michigan is a cable television operator in the State
of Michigan which, as of December 31, 1997, served approximately 204,000
subscribers including approximately 39,400 subscribers served by Mercom.
Clustered primarily around the Michigan communities of Grand Rapids, Traverse
City, Lapeer and Monroe (Mercom), Cable Michigan's systems serve a total of
approximately 400 municipalities in suburban markets and small towns. On June
4, 1998, Cable Michigan announced that it had agreed to be acquired by Avalon
Cable. Level 3 received approximately $129 million in cash when the transaction
closed on November 6, 1998.
 
 Coal Mining
 
   The Company is engaged in coal mining through its subsidiary, KCP Inc.
("KCP"). KCP has a 50% interest in three mines, which are operated by a
subsidiary of New PKS. Decker Coal Company ("Decker") is a joint venture with
Western Minerals, Inc., a subsidiary of The RTZ Corporation PLC. Black Butte
Coal Company ("Black Butte") is a joint venture with Bitter Creek Coal Company,
a subsidiary of Union Pacific Resources Group Inc. Walnut Creek Mining Company
("Walnut Creek") is a general partnership with Phillips Coal Company, a
subsidiary of Phillips Petroleum Company. The Decker mine is located in
southeastern Montana, the Black Butte mine is in southwestern Wyoming, and the
Walnut Creek mine is in east-central Texas. The coal mines use the surface
mining method. For a discussion of certain risks associated with the coal
mining business, see "Risk Factors--Environmental liabilities from our
historical operations could be material," "--Significant future declines in
cash flow from coal operations" and "--Potential liabilities and claims arising
from our coal operations could be significant."
 
   The coal produced from the KCP mines is sold primarily to electric
utilities, which burn coal in order to produce steam to generate electricity.
Approximately 89% of sales are made under long-term contracts, and the
remainder are made on the spot market. Approximately 79%, 80% and 80% of KCP's
revenues in 1997, 1996 and 1995, respectively, were derived from long-term
contracts with Commonwealth Edison (with Decker and Black Butte) and The
Detroit Edison Company (with Decker). The primary customer of Walnut Creek is
the Texas-New Mexico Power Company ("TNP"). KCP also has other sales
commitments, including those with Sierra Pacific, Idaho Power, Solvay Minerals,
Pacific Power & Light, Minnesota Power, and Mississippi Power, that provide for
the delivery of approximately 13 million tons through 2005. The level of cash
flows generated in recent periods by the Company's coal operations will not
continue after the year 2000 because the delivery requirements under the
Company's current long-term contracts decline significantly.
 
   Under a mine management agreement, KCP pays a subsidiary of New PKS an
annual fee equal to 30% of KCP's adjusted operating income. The fee in 1998 was
$34 million.
 
   The coal industry is highly competitive. KCP competes not only with other
domestic and foreign coal suppliers, some of whom are larger and have greater
capital resources than KCP, but also with alternative methods of generating
electricity and alternative energy sources. In 1996, KCP's production
represented 1.5% of total U.S. coal production. Demand for KCP's coal is
affected by economic, political and regulatory factors. For example, recent
"clean air" laws may stimulate demand for low sulfur coal. KCP's western coal
reserves
 
                                      S-50
<PAGE>
 
generally have a low sulfur content (less than one percent) and are currently
useful principally as fuel for coal-fired, steam-electric generating units.
 
   KCP's sales of its western coal, like sales by other western coal producers,
typically provide for delivery to customers at the mine. A significant portion
of the customer's delivered cost of coal is attributable to transportation
costs. Most of the coal sold from KCP's western mines is currently shipped by
rail to utilities outside Montana and Wyoming. The Decker and Black Butte mines
are each served by a single railroad. Many of their western coal competitors
are served by two railroads and such competitors' customers often benefit from
lower transportation costs because of competition between railroads for coal
hauling business. Other western coal producers, particularly those in the
Powder River Basin of Wyoming, have lower stripping ratios (that is, the amount
of overburden that must be removed in proportion to the amount of minable coal)
than the Black Butte and Decker mines, often resulting in lower comparative
costs of production. As a result, KCP's production costs per ton of coal at the
Black Butte and Decker mines can be as much as four and five times greater than
production costs of certain competitors. KCP's production cost disadvantage has
contributed to its agreement to amend its long-term contract with Commonwealth
Edison to provide for delivery of coal from alternate source mines rather than
from Black Butte. Because of these cost disadvantages, KCP does not expect that
it will be able to enter into long-term coal purchase contracts for Black Butte
and Decker production as the current long-term contracts expire. In addition,
these cost disadvantages may adversely affect KCP's ability to compete for spot
sales in the future.
 
   The Company is required to comply with various federal, state and local laws
and regulations concerning protection of the environment. KCP's share of land
reclamation expenses in 1998 was approximately $4 million. KCP's share of
accrued estimated reclamation costs was $96 million at the end of 1998. The
Company did not make significant capital expenditures for environmental
compliance with respect to the coal business in 1998. The Company believes its
compliance with environmental protection and land restoration laws will not
affect its competitive position since its competitors in the mining industry
are similarly affected by such laws. However, failure to comply with
environmental protection and land restoration laws, or actual reclamation costs
in excess of the Company's accruals, could have an adverse effect on the
Company's business, results of operations, or financial condition.
 
 SR91 Tollroad
 
   The Company has invested $12 million for a 65% equity interest and lent $5.1
million to California Private Transportation Company L.P. ("CPTC"), which
developed, financed, and currently operates the 91 Express Lanes, a ten mile,
four-lane tollroad in Orange County, California (the "SR91 Tollroad"). The
fully automated highway uses an electronic toll collection system and variable
pricing to adjust tolls to demand. Capital costs at completion were $130
million, $110 million of which was funded with debt that was not guaranteed by
Level 3. However, certain defaults by Level 3 on its outstanding debt and
certain judgments against Level 3 can result in default under this debt of
CPTC. Revenue collected over the 35-year franchise period is used for operating
expenses, debt repayment, and profit distributions. The SR91 Tollroad opened in
December 1995 and achieved operating break-even in 1996. Approximately 91,500
customers have registered to use the tollroad as of December 1998, and weekday
volumes typically exceed 27,000 vehicles per day during December 1998.
 
Employees
 
   As of December 31, 1998, Level 3 had 1,225 employees in the communications
portion of its business and PKSIS had approximately 959 employees, for a total
of 2,184 employees.
 
Properties
 
   The Company has announced that it has acquired 46 acres in the Northwest
corner of the Interlocken office park within the City of Broomfield, Colorado,
and within Boulder County, Colorado limits and will build
 
                                      S-51
<PAGE>
 
a campus facility that is expected to encompass eventually over 500,000 square
feet of office space. Construction has begun on this facility, and it is
anticipated that the first phase of this facility will be completed by the
summer of 1999. In addition, the Company has leased approximately 250,000
square feet of temporary office space in Louisville, Colorado to allow for the
relocation of the majority of its employees (other than those of PKSIS) while
its permanent facilities are under construction. Properties relating to the
Company's coal mining segment are described under "--The Company's Other
Businesses" above. In connection with certain existing and historical
operations, the Company is subject to environmental risks. See "Risk Factors--
Environmental liabilities from our historical operations could be material."
 
   The Company has approximately 1.25 million square feet of space for its
gateway facilities. The Company's gateway facilities are being designed to
house local sales staff, operational staff, the Company's transmission and IP
routing/switching facilities and technical space to accommodate colocation of
equipment by high-volume Level 3 customers.
 
   PKSIS maintains its corporate headquarters in Omaha, Nebraska and leases
approximately 35,000 square feet of office space in Omaha. The computer
outsourcing business of PKSIS is located at an 89,000 square foot office space
in Omaha and at a 60,000 square foot computer center in Tempe, Arizona. PKSIS
maintains additional office space in Phoenix, Atlanta, Omaha and Parsippany for
its systems integration business.
 
Legal Proceedings
 
   The Company and its subsidiaries are parties to many pending legal
proceedings. Management believes that any resulting liabilities for legal
proceedings, beyond amounts reserved, will not materially affect the Company's
financial condition, future results of operations, or future cash flows.

                     CERTAIN TRANSACTIONS AND RELATIONSHIPS
 
   All share information has been adjusted to reflect the Company's 2-for-1
stock split, effected as a stock dividend in August 1998.
 
   In connection with his retention as Chief Executive Officer of the Company,
Mr. Crowe entered into an engagement agreement (the "Engagement Agreement")
with the Company. Under the Engagement Agreement, the Company acquired from Mr.
Crowe, Mr. Bradbury and an additional individual, Broadband Capital Group,
L.L.C., a company formed to develop investment opportunities, for a purchase
price of $68,523, the owners' cash investment in that company. Pursuant to the
Engagement Agreement, the Company sold 10,000,000 shares of Class D Stock to
Mr. Crowe and 2,500,000 shares of Class D Stock to Mr. Bradbury, in each case
at $5.425 per share. The Engagement Agreement also provided that the Company
would make available for sale, from time to time prior to the consummation of
the split-off, to certain employees of the Company designated by Mr. Crowe in
connection with the implementation of the Business Plan ("Business Plan
Employees"), up to an aggregate of 10,500,000 shares of Class D Stock.
 
   On August 5, 1997, the Company purchased a jet aircraft from a company
controlled by Mr. Crowe for $5.7 million, the price paid by the company for the
aircraft in June 1997. The Company and Mr. Crowe have entered into an aircraft
operating lease, under which Mr. Crowe may lease the aircraft for personal use
at rates specified by certain Federal Aviation Administration regulations. The
Company anticipates that Mr. Crowe will lease approximately 15% of the
aircraft's annual flight time, and will pay the Company approximately $70,000
per year at the current lease rate.
 
   The Company entered into a separation agreement with Mr. Jaros, a director
of the Company, in connection with the resignation of Mr. Jaros as President of
the Diversified Group effective July 31, 1997. Under the separation agreement,
the Company paid Mr. Jaros $1.8 million on July 31, 1997 and agreed to pay Mr.
Jaros the balance of his 1997 salary ($187,500) between August 1 and December
31, 1997 and a bonus payment of $262,350 when the Company made its customary
executive bonus payments in 1998. The Company also agreed to amend the option
agreements with Mr. Jaros with respect to the options to purchase 1,500,000
shares of Class D Stock at $4.04 per share granted to Mr. Jaros in 1995, and
the options to purchase 500,000 shares of Class D Stock at $4.95 per share
granted to Mr. Jaros in 1996, to provide that those options would be fully
vested on July 31, 1997, and would be exercisable at any time during the ten-
year term of the original option agreements.
 
   On July 1, 1998, the Company issued 187,706 shares of its common stock to
Mr. Williams, an Executive Vice President of the Company, in connection with
the Company's acquisition of UltraLine (Bermuda) Limited, a company owned by
Mr. Williams. The value of the transaction, based upon the trading price of its
common stock on that date, was approximately $5 million.
 
   In connection with the split-off, Level 3 and Peter Kiewit Sons', Inc., or
New PKS, entered into various agreements intended to implement the split-off,
including a Separation Agreement and a Tax-Sharing Agreement.
 
   Separation Agreement. Level 3 and New PKS entered into a separation
agreement (the "Separation Agreement") relating to the allocation of certain
risks and responsibilities between New PKS and Level 3 after the split-off and
certain other matters. The Separation Agreement provides that each of New PKS
and Level 3 will indemnify the other with respect to the activities of its
subsidiary business groups, except as specifically provided under other
agreements between the companies. The cross-indemnities are intended to
allocate financial responsibility to New PKS for liabilities arising out of the
construction businesses formerly conducted by Level 3, and to allocate to Level
3 financial responsibility for liabilities arising out of the non-construction
businesses conducted by Level 3. The Separation Agreement also allocates
between New PKS and Level 3 certain corporate-level risk exposures not readily
allocable to either the construction businesses or the non-construction
businesses.
 
                                      S-57
<PAGE>
 
   The Separation Agreement provides that each of Level 3 and New PKS will be
granted access to certain records and information in the possession of the
other company, and requires that each of Level 3 and New PKS retain all such
information in its possession for a period of ten years following the split-
off. Under the Separation Agreement, each company is required to give the other
company prior notice of any intention to dispose of any such information.
 
   The Separation Agreement provides that, except as otherwise set forth
therein or in any related agreement, costs and expenses in connection with the
split-off will be paid 82.5% by Level 3 and 17.5% by New PKS. On March 18,
1998, Level 3 and New PKS entered into an amendment to the Separation Agreement
that provides that New PKS will bear substantially all of those expenses if the
Level 3 Board determines to force conversion of all outstanding Class R Stock
of Level 3 on or before July 15, 1998 (a "Forced Conversion Determination").
The Level 3 Board made such a determination and, accordingly, substantially all
of those expenses will be borne by New PKS.
 
   Tax Sharing Agreement. Level 3 and New PKS have entered into a tax sharing
agreement (the "Tax Sharing Agreement") that defines each company's rights and
obligations with respect to deficiencies and refunds of federal, state and
other taxes relating to operations for tax years (or portions thereof) ending
prior to the split-off and with respect to certain tax attributes of Level 3
and New PKS after the split-off. Under the Tax Sharing Agreement, with respect
to periods (or portions thereof) ending on or before the split-off, Level 3 and
New PKS generally will be responsible for paying the taxes relating to such
returns (including any subsequent adjustments resulting from the
redetermination of such tax liabilities by the applicable taxing authorities)
that are allocable to the non-construction business and the construction
business, respectively.
 
   The Tax Sharing Agreement also provides that Level 3 and New PKS will
indemnify the other from certain taxes and expenses that would be assessed on
New PKS and Level 3, respectively, if the split-off were determined to be
taxable, but solely to the extent that such determination arose out of the
breach by Level 3 or New PKS, respectively, of certain representations made to
the Internal Revenue Service in connection with the private letter ruling
issued with respect to the split-off. Under the Tax Sharing Agreement, if the
split-off were determined to be taxable for any other reason, those taxes and
certain other taxes associated with the split-off (together, "Split-Off Taxes")
would be allocated 82.5% to Level 3 and 17.5% to New PKS. The Tax Sharing
Agreement, however, provides that Split-Off Taxes will be allocated one-half to
each of Level 3 and New PKS if a Forced Conversion Determination is made. As a
result of the Forced Conversion Determination, the Split-Off Taxes will be so
allocated. Finally, the Tax Sharing Agreement provides, under certain
circumstances, for certain liquidated damage payments from Level 3 to New PKS
if the split-off were determined to be taxable, which are intended to
compensate stockholders of New PKS indirectly for taxes assessed upon them in
that event. Those liquidated damage payments, however, are reduced because of
the Forced Conversion Determination.
 
   Mine Management Agreement. In 1992, New PKS and Level 3 entered into a mine
management agreement (the "Mine Management Agreement") pursuant to which a
subsidiary of New PKS, Kiewit Mining Group Inc. ("KMG"), provides mine
management and related services for Level 3's coal mining properties. In
consideration of the provision of such services, KMG receives a fee equal to
thirty percent of the adjusted operating income of the coal mining properties.
The term of the Mine Management Agreement expires on January 1, 2016.
 
   In connection with the split-off, the Mine Management Agreement was amended
to provide KMG with a right of offer in the event that Level 3 were to
determine to sell any or all of its coal mining properties. Under the right of
offer, Level 3 would be required to offer to sell those properties to KMG at
the price that Level 3 would seek to sell the properties to a third party. If
KMG were to decline to purchase the properties at that price, Level 3 would be
free to sell them to a third party for an amount greater than or equal to that
price. If Level 3 were to sell the properties to a third party, thus
terminating the Mine Management Agreement, it would be required to pay KMG an
amount equal to the discounted present value to KMG of the Mine Management
Agreement, determined, if necessary, by an appraisal process.

                     CERTAIN UNITED STATES TAX CONSEQUENCES
                          TO NON-UNITED STATES HOLDERS
 
   A general discussion of certain United States federal income and estate tax
consequences of the acquisition, ownership and disposition of common stock
applicable to Non-U.S. Holders (as defined) of common stock is set forth below.
In general, a "Non-U.S. Holder" is a person other than: (i) a citizen or
resident (as defined for United States federal income or estate tax purposes,
as the case may be) of the United States; (ii) a corporation or other entity
taxable as a corporation organized in or under the laws of the United States or
a political subdivision thereof; (iii) an estate the income of which is subject
to United States federal income taxation regardless of its source, or (iv) a
trust if and only if (A) a court within the United States is able to exercise
primary supervision over the administration of the trust and (B) one or more
United States trustees have the authority to control all substantial decisions
of the trust. The discussion is based on current law and is provided for
general information only. The discussion does not address aspects of United
States federal taxation other than 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 and does not address all aspects of United States federal
income and estate tax laws that may be relevant to Non-U.S. Holders that may be
subject to a special treatment under such laws (for example, insurance
companies, tax-exempt organizations, financial institutions or broker-dealers).
This discussion is based on the Internal Revenue Code of 1986, as amended,
Treasury Regulations promulgated thereunder and administrative and judicial
interpretations thereof, all of which are subject to change, possibly with
retroactive effect. ACCORDINGLY, PROSPECTIVE INVESTORS ARE URGED TO CONSULT
THEIR TAX ADVISORS REGARDING THE UNITED STATES FEDERAL, STATE, LOCAL AND
FOREIGN INCOME AND OTHER TAX CONSEQUENCES OF ACQUIRING, HOLDING AND DISPOSING
OF COMMON STOCK.
 
Dividends
 
   In general, the gross amount of dividends paid to a Non-U.S. Holder will be
subject to United States withholding tax at a 30% rate (or any lower rate
prescribed by an applicable tax treaty) unless the dividends are (i)
effectively connected with a trade or business carried on by the Non-U.S.
Holder within the United States and a Form 4224 is filed with the withholding
agent or (ii) if a tax treaty applies, are attributable to a United States
permanent establishment of the Non-U.S. Holder. If either exception applies,
the dividend will be taxed at ordinary U.S. federal income tax rates. A Non-
U.S. Holder may be required to satisfy certain certification requirements in
order to claim the benefit of an applicable treaty rate or otherwise claim a
reduction of, or exemption from, the withholding obligation pursuant to the
above described rules. In the case of a Non-U.S. Holder that is a corporation,
effectively connected income may also be subject to the branch profits tax,
except to the extent that an applicable tax treaty provides otherwise.
 
Sale of 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 common stock
unless: (i) the Company has been, is, or becomes a "U.S. real property holding
corporation" for federal income tax purposes, such Non-U.S. Holder owned more
than 5% of the common stock sold during a specified period, and certain other
requirements are met; (ii) the gain is effectively connected with a trade or
business carried on by the Non-U.S. Holder within the United States; (iii) the
common stock is disposed of by an individual Non-U.S. Holder who holds the
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 or (iv) the Non-U.S. Holder
is an individual who lost his U.S. citizenship within the last 10 years and
such loss had, as one of its principal purposes, the avoidance of taxes, and
the gains are considered derived from sources within the United States. The
Company believes that it has not been, is not currently and, based upon its
current business plans, is not likely to become a U.S. real property holding
corporation. Non-U.S. Holders should consult applicable treaties, which may
exempt from United States taxation gains realized upon the disposition of
common stock in certain cases.

Estate Tax
 
   Common stock owned or treated as owned by an individual Non-U.S. Holder at
the time of his death will be includible in the individual's gross estate for
United States federal estate tax purposes, unless an applicable treaty provides
otherwise, and may be subject to United States federal estate tax.
 
Backup Withholding and Information Reporting Requirements
 
   On October 14, 1997, the IRS issued final regulations relating to
withholding, information reporting and backup withholding that unify current
certification procedures and forms and clarify reliance standards (the "Final
Regulations"). The Final Regulations were intended to be effective with respect
to payments made after December 31, 1998. The IRS has, however, recently issued
a notice stating that such Final Regulations will not be effective until
January 1, 2000.
 
   Except as provided below, this section describes rules applicable to
payments made on or before the Final Regulations take effect. Backup
withholding (which generally is a withholding tax imposed at the rate of 31% on
certain payments to persons that fail to furnish the information required under
the United States information reporting and backup withholding rules) generally
will not apply to (i) dividends paid to Non-U.S. Holders that are subject to
the 30% withholding discussed above (or that are not so subject because a tax
treaty applies that reduces or eliminates such 30% withholding) or (ii)
dividends paid on the common stock to a Non-U.S. Holder at an address outside
the United States. The Company will be required to report annually to the IRS
and to each Non-U.S. Holder the amount of dividends paid to, and the tax
withheld with respect to, such holder, regardless of whether any tax was
actually withheld. This information may also be made available to the tax
authorities in the Non-U.S. Holder's country of residence.
 
   In the case of a Non-U.S. Holder that sells common stock to or through a
United States office of a broker, the broker must backup withhold at a rate of
31% and report the sale to the IRS, unless the holder certifies its Non-U.S.
status under penalties of perjury or otherwise establishes an exemption. In the
case of a Non-U.S. Holder that sells common stock to or through the foreign
office of a United States broker, or a foreign broker with certain types of
relationships to the United States, the broker must report the sale to the IRS
(but not backup withhold) unless the broker has documentary evidence in its
files that the seller is a Non-U.S. Holder or certain other conditions are met,
or the holder otherwise establishes an exemption. A Non-U.S. Holder will
generally not be subject to information reporting or backup withholding if such
Non-U.S. Holder sells the common stock to or through a foreign office of a non-
United States broker.
 
   Any amount withheld under the backup withholding rules from a payment to a
Non-U.S. Holder is allowable as a credit against the holder's U.S. federal
income tax, which may entitle the Non-U.S. Holder to a refund, provided that
the holder furnishes the required information to the IRS. In addition, certain
penalties may be imposed by the IRS on a Non-U.S. Holder who is required to
supply information but does not do so in the proper manner.
 
   The Final Regulations eliminate the general current law presumption that
dividends paid to an address in a foreign country are paid to a resident of
that country. In addition, the Final Regulations impose certain certification
and documentation requirements on Non-U.S. Holders claiming the benefit of a
reduced withholding rate with respect to dividends under a tax treaty.
 
   Prospective purchasers of common stock are urged to consult their tax
advisors as to the application of the current rules regarding backup
withholding and information reporting and as to the effect, if any, of the
Final Regulations on their acquisition, ownership and disposition of the common
stock.

   The underwriting agreement provides that the obligations of the several
underwriters to purchase the shares included in this offering are subject to
approval of certain legal matters by counsel and to certain other conditions.
The underwriters are obligated to purchase all the shares (other than those
covered by the over-allotment option described below) if they purchase any of
the shares.
 
   The underwriters, for whom Salomon Smith Barney Inc., Goldman, Sachs & Co.,
Credit Suisse First Boston Corporation, Merrill Lynch, Pierce, Fenner & Smith
Incorporated, J.P. Morgan Securities Inc. and Morgan Stanley & Co. Incorporated
are acting as representatives, propose to offer some of the shares directly to
the public at the public offering price set forth on the cover page of this
prospectus supplement and some of the shares to certain dealers at the public
offering price less a concession not in excess of $    per share. The
underwriters may allow, and such dealers may reallow, a concession not in
excess of $    per share on sales to certain other dealers. After the initial
offering of the shares to the public, the public offering price and such
concessions may be changed by the representatives.
 
   Level 3 has granted to the underwriters an option, exercisable for 30 days
from the date of this prospectus supplement, to purchase up to 3,000,000
additional shares of its common stock at the public offering price less the
underwriting discount. The underwriters may exercise such option solely for the
purpose of covering over-allotments, if any, in connection with this offering.
To the extent such option is exercised, each underwriter will be obligated,
subject to certain conditions, to purchase a number of additional shares
approximately proportionate to such underwriter's initial purchase commitment.
 
   Level 3 has agreed that, for a period of 90 days from the date of this
prospectus supplement, it will not, without the prior written consent of
Salomon Smith Barney Inc., offer, sell, contract to sell, issue, announce the
offering or issuance of, register, cause to be registered or announce the
registration or intended registration of, in any case for its own account, any
shares of common stock of Level 3, including any such shares beneficially or
indirectly owned or controlled by Level 3, or any securities convertible into
or exchangeable for common stock, except for: (1) up to 2,000,000 shares of
common stock issued in connection with acquisitions, provided that this limit
may be exceeded if the purchaser of such shares agrees to be bound for any
remaining portion of the 90-day "black-out"period, (2) common stock issued in
connection with the acquisition of BusinessNet
Limited, (3) common stock issued pursuant to any employee benefit plan, stock
ownership or stock option plan or dividend reinvestment plan in effect on the
date hereof or options granted pursuant to any such plan in effect on the date
hereof, provided that such options cannot be exercised for any remaining
portion of the 90-day "black-out" period, (4) common stock issued in connection
with the inclusion of Level 3's common stock in

date hereof or otherwise permitted to be filed under this paragraph, (6) common
stock issued in connection with the exercise of any warrants outstanding on the
date hereof, (7) common stock issued to prospective employees in connection
with such employees being hired by Level 3 and (8) common stock issued in this
offering. Salomon Smith Barney Inc. in its sole discretion may release any of
the securities subject to these "black-out" agreements at any time without
notice.

   In connection with the offering, Salomon Smith Barney Inc., on behalf of the
underwriters, may over-allot, or engage in syndicate covering transactions,
stabilizing transactions and penalty bids. Over-allotment involves syndicate
sales of common stock in excess of the number of shares to be purchased by the
underwriters in the offering, which creates a syndicate short position.
Syndicate covering transactions involve purchases of the common stock in the
open market after the distribution has been completed in order to cover
syndicate short positions. Stabilizing transactions consist of certain bids or
purchases of common stock made for the purpose of preventing or retarding a
decline in the market price of the common stock while the offering is in
progress. Penalty bids permit the underwriters to reclaim a selling concession
from a syndicate member when Salomon Smith Barney Inc., in covering syndicate
short positions or making stabilizing purchases, repurchases shares originally
sold by that syndicate member. These activities may cause the price of the
common stock to be higher than the price that otherwise would exist in the open
market in the absence of such transactions. These transactions may be effected
on the Nasdaq National Market or in the over-the-counter market, or otherwise
and, if commenced, may be discontinued at any time.
 
   In addition, in connection with this offering, certain of the underwriters
(and selling group members) may engage in passive market making transactions in
Level 3's common stock on the Nasdaq National Market, prior to the pricing and
completion of the offering. Passive market making consists of displaying bids
on the Nasdaq National Market no higher than the bid prices of independent
market makers and making purchases at prices no higher than those independent
bids and effective in response to order flow. Net purchases by a passive market
maker on each day are limited to a specified percentage of the passive market
maker's average daily trading volume in the common stock during a specified
period and must be discontinued when such limit is reached. Passive market
making may cause the price of Level 3's common stock to be higher than the
price that otherwise would exist in the open market in the absence of such
transactions. If passive market making is commenced, it may be discontinued at
any time.
 
   Level 3 estimates that its total expenses of this offering will be $2
million.
 
   The representatives have performed certain investment banking and advisory
services for Level 3 from time to time for which they have received customary
fees and expenses. The representatives may, from time to time, engage in
transactions with and perform services for Level 3 in the ordinary course of
their business.
 
   Level 3 has agreed to indemnify the underwriters against certain
liabilities, including liabilities under the Securities Act of 1933, or to
contribute to payments the underwriters may be required to make in respect of
any of those liabilities.

                 LEVEL 3 COMMUNICATIONS, INC. AND SUBSIDIARIES
 
              NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS
 
1. Basis of Presentation
 
   The financial statements of Level 3 Communications, Inc. and subsidiaries
("Level 3" or the "Company") contained herein are unaudited and, in the opinion
of management, contain all adjustments (consisting only of normal recurring
accruals) necessary for a fair presentation of financial position, results of
operations and cash flows for the periods presented. The Company's accounting
policies and certain other disclosures are set forth in the notes to the
consolidated financial statements contained elsewhere herein, for the year
ended December 27, 1997. These financial statements should be read in
conjunction with the Company's audited consolidated financial statements and
notes thereto. The preparation of the consolidated condensed financial
statements in conformity with generally accepted accounting principles requires
management to make estimates and assumptions that affect the reported amount of
assets and liabilities, disclosure of contingent assets and liabilities and the
reported amount of revenue and expenses during the reported period. Actual
results could differ from these estimates.
 
   In 1997, the Company agreed to sell its energy assets to CalEnergy Company,
Inc. ("CalEnergy") and to separate the construction operations ("Construction &
Mining Group") from the Company. On January 2, 1998, the Company completed the
sale of its energy assets to CalEnergy. On March 31, 1998, the Company
completed the split-off of the Construction & Mining Group to stockholders that
held Class C Stock. Therefore, the results of operations of both businesses
have been classified as discontinued operations on the statements of operations
for all periods presented. Only the results of operations of the energy
business have been reflected as discontinued on the statement of cash flows.
 
   The Company is currently constructing its communications network. Costs
associated directly with the uncompleted network and interest expense incurred
during construction are capitalized. As segments of the network become
operational, the assets will be depreciated over their useful lives.
 
   The Company is currently developing business support systems. The external
direct costs of software, materials and services, payroll and payroll related
expenses for employees directly associated with the project, and interest costs
incurred when developing the business support systems are capitalized. Upon
completion of the project, the total cost of the business support systems will
be amortized over its useful life.
 
   The capitalized business support systems and network construction costs
incurred to date of $364 million, have been classified as assets under
construction within Property, Plant & Equipment in the accompanying
consolidated condensed balance sheet.
 
   The results of operations for the three and nine months ended September 30,
1998, are not necessarily indicative of the results to be expected for the full
year.
 
   On May 1, 1998, the Company's Board of Directors changed Level 3's fiscal
year end from the last Saturday in December to a calendar year end. The
additional five days in the 1998 fiscal year will be reflected in the Company's
Form 10-K for the period ended December 31, 1998.
 
   Where appropriate, items within the consolidated condensed financial
statements have been reclassified from the previous periods to conform to
current period presentation.
 
2. Reorganization--Discontinued Construction Operations
 
   On March 31, 1998, a separation of the Company's Construction & Mining Group
and Diversified Group was completed through the split-off of the Construction
and Mining Group (the "Split-off").

                 LEVEL 3 COMMUNICATIONS, INC. AND SUBSIDIARIES
 
       NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS--(Continued)
 
 
   The Company recognized a gain of $608 million equal to the difference
between the carrying value of the Construction & Mining Group and its fair
value in accordance with the Financial Accounting Standards Board Emerging
Issues Tax Force Issue 96-4. No taxes were provided on this gain due to the
tax-free nature of the Split-off. The Company then reflected the fair value of
the Construction & Mining Group as a distribution to the Class C stockholders.
 
   In connection with the Split-off, Level 3 and the Construction & Mining
Group entered into various agreements including a Separation Agreement, a Tax
Sharing Agreement and an amended Mine Management Agreement.
 
   The Separation Agreement, as amended, provides for the allocation of certain
risks and responsibilities between Level 3 and the Construction & Mining Group
and for cross-indemnifications that are intended to allocate financial
responsibility to the Construction & Mining Group for liabilities arising out
of the construction business and to allocate to Level 3 financial
responsibility for liabilities arising out of the non-construction businesses.
The Separation Agreement also allocates certain corporate-level risk exposures
not readily allocable to either the construction businesses or the non-
construction businesses.
 
   Under the Tax Sharing Agreement, with respect to periods, or portions
thereof, ending on or before the Split-off, Level 3 and the Construction &
Mining Group generally will be responsible for paying the taxes relating to
such returns, including any subsequent adjustments resulting from the
redetermination of such tax liabilities by the applicable taxing authorities,
that are allocable to the non-construction businesses and construction
businesses, respectively. The Tax Sharing Agreement also provides that Level 3
and the Construction & Mining Group will indemnify the other from certain taxes
and expenses that would be assessed if the Split-off were determined to be
taxable, but solely to the extent that such determination arose out of the
breach by Level 3 or the Construction & Mining Group, respectively, of certain
representations made to the Internal Revenue Service in connection with the
private letter ruling issued with respect to the Split-off. If the Split-off
were determined to be taxable for any other reason, those taxes would be
allocated equally to Level 3 and the Construction & Mining Group. Finally,
under certain circumstances, Level 3 would make certain liquidated damage
payments to the Construction & Mining Group if the Split-off was determined to
be taxable, in order to indirectly compensate Class C stockholders for taxes
assessed upon them in that event.
 
   In connection with the Split-off, the Mine Management Agreement, pursuant to
which the Construction & Mining Group provides mine management and related
services to Level 3's coal mining operations, was amended to provide the
Construction & Mining Group with a right of offer in the event that Level 3
were to determine to sell any or all of its coal mining properties. Under the
right of offer, Level 3 would be required to offer to sell those properties to
the Construction & Mining Group. If the Construction & Mining Group were to
decline to purchase the properties at that price, Level 3 would be free to sell
them to a third party for an amount greater than or equal to that price. If
Level 3 were to sell the properties to a third party, thus terminating the Mine
Management Agreement, it would be required to pay the Construction & Mining
Group an amount equal to the discounted present value of the Mine Management
Agreement, determined, if necessary, by an appraisal process.
 
   Following the Split-off, the Company's common stock began trading on The
Nasdaq National Market on April 1, 1998, under the symbol "LVLT". In connection
with the Split-off, the construction business was renamed "Peter Kiewit Sons',
Inc." and the Class D Stock became the common stock of Level 3 Communications,
Inc. ("Common Stock"). Accordingly, the separate financial statements of Peter
Kiewit Sons', Inc. should be obtained to review the results of operations of
the Construction & Mining Group for the three and nine months ended September
30, 1997.
 
   The Company's certificate of incorporation gave stockholders the right to
exchange their Class C Stock for Class D Stock under a set conversion formula.
That right was eliminated as a result of the Split-off. To replace

       NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS--(Continued)
 
that conversion right, Class C stockholders received 6.5 million shares of a
new Class R Convertible Stock ("Class R Stock") in January 1998, which was
convertible into Level 3 Common Stock in accordance with terms ratified by
stockholders in December 1997. The Company reflected in the equity accounts the
exchange of the conversion right and issuance of the Class R Stock at its fair
value of $92 million at the date of the Split-off.
 
   On May 1, 1998, the Board of Directors of Level 3 Communications, Inc.
determined to force conversion of all shares of the Company's Class R Stock
into common stock of the Company, effective May 15, 1998. The Class R Stock was
converted into Level 3 Common Stock in accordance with the formula set forth in
the Certificate of Incorporation of the Company. The formula provided for a
conversion ratio equal to $25, divided by the average of the midpoints between
the high and low sales prices for Level 3 Common Stock on each of the fifteen
trading days during the period beginning April 9 and ending April 30. The
average for that period was $32.14, adjusted for the stock dividend issued
August 10, 1998. Accordingly, each holder of Class R Stock received .7778 of a
share of Level 3 Common Stock for each share of Class R Stock held. In total
6.5 million shares of Class R Stock were converted into 5.1 million shares of
Common Stock. The value of the Class R Stock at the time of the forced
conversion was $25 times the 6.5 million shares outstanding, or $164 million.
The Company recognized the additional $72 million of value upon conversion of
the Class R Stock to Common Stock. As a result of the forced conversion,
certain adjustments were made to the cost sharing and risk allocation
provisions of the Separation Agreement and Tax Sharing Agreement between the
Company and Peter Kiewit Sons', Inc. which reduced the costs and risks
allocated to the Company.
 
   The Company has embarked on a plan to become a facilities-based provider
(that is, a provider that owns or leases a substantial portion of the plant,
property and equipment necessary to provide its services) of a broad range of
integrated communications services. To reach this goal, the Company plans to
expand substantially the business of its PKS Information Services, Inc.
subsidiary and to create, through a combination of construction, purchase and
leasing of facilities and other assets, an international, end-to-end,
facilities-based communications network (the "Business Plan"). The Company is
designing the network based on Internet Protocol ("IP") technology in order to
leverage the efficiencies of this technology to provide lower cost
communications services.
 
3. Discontinued Energy Operations
 
   On January 2, 1998, the Company completed the sale of its energy assets to
CalEnergy. Level 3 recognized an after-tax gain on the disposition of $324
million and the after-tax proceeds of approximately $967 million from the
transaction are being used to fund in part the Business Plan. Results of
operations for the period through January 2, 1998, were not considered
significant and the gain on disposition was calculated using the carrying
amount of the energy assets as of December 27, 1997.
 
 
4. Earnings Per Share
 
   Basic earnings per share have been computed using the weighted average
number of shares during each period. Diluted earnings per share have been
computed by including stock options considered to be potentially dilutive
common shares.
 
   The Company had a loss from continuing operations for the three and nine
month periods ended September 30, 1998, therefore, no potential common shares
related to Company stock options have been included in the computation of the
diluted earnings per share because the resulting computation would be anti-
dilutive. For the periods ending September 30, 1997, potentially dilutive stock
options are calculated in accordance with the treasury stock method which
assumes that proceeds from exercise of all options are used to repurchase
common stock at the average market value. The number of shares remaining after
the proceeds are exhausted represent the potentially dilutive effect of the
options.

   The Company had 19,690,144 options outstanding that were not included in the
computation of diluted earnings per share because to do so would have been
anti-dilutive for the three and nine month periods ended September 30, 1998.
 
   Effective August 10, 1998, and December 26, 1997, the Company issued
dividends of one share and four shares of Level 3 Common Stock (previously
Class D Stock) for each share of Level 3 Common Stock outstanding. All share
information and per share data have been restated to reflect these stock
dividends.
 
5. Acquisitions
 
   On April 23, 1998, the Company acquired XCOM Technologies, Inc. ("XCOM"), a
privately held company that has developed technology which the Company believes
will provide certain key components necessary for the Company to develop an
interface between its IP-based network and the public switched telephone
network. The Company issued approximately 5.3 million restricted shares of
Level 3 Common Stock and 0.8 million options and warrants to purchase Level 3
Common Stock in exchange for all the stock, options and warrants of XCOM.
 
   The Company accounted for this transaction, valued at $154 million, as a
purchase. Of the total purchase price, $115 million was attributable to in-
process research and development, and was taken as a nondeductible
 
                                      F-10

       NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS--(Continued)
 
charge to earnings in the second quarter of 1998. The purchase price exceeded
the fair value of the net assets acquired by $30 million which was recognized
as goodwill and is being amortized over five years.
 
   On September 30, 1998, Level 3 acquired GeoNet Communications, Inc.
("GeoNet"), a regional Internet service provider located in Northern
California. The Company issued approximately 0.6 million shares and options in
exchange for GeoNet's capital stock, which based on Level 3's closing price on
September 30, valued the transaction at approximately $19 million. Goodwill of
$20 million was recognized from this transaction and will be amortized over
five years.
 
   XCOM's and GeoNet's 1997 and 1998 operating results prior to the
acquisitions were not significant relative to the Company's results.
 
   For the Company's acquisitions, the excess purchase price over the fair
market value of the underlying assets was allocated to goodwill, other
intangible assets and property based upon preliminary estimates of fair value.
The Company does not believe that the final purchase price allocation will vary
significantly from the preliminary purchase price allocation.
 
6. Investments
 
   In September 1997, C-TEC Corporation ("C-TEC") announced that its Board of
Directors had approved the planned restructuring of C-TEC into three publicly
traded companies effective September 30, 1997. Under the terms of the
restructuring C-TEC stockholders received stock in the following companies:
 
     Commonwealth Telephone Enterprises, Inc., containing the local telephone
  group and related engineering business;
 
     Cable Michigan, Inc. containing the cable television operation; and
 
     RCN Corporation, Inc. which consists of RCN Telecom Services; C-TEC,
  existing cable systems in the Boston-Washington D.C. corridor; and the
  investment in Megacable S.A. de C.V., a cable operator in Mexico. RCN
  Telecom Services is a provider of packaged local and long distance
  telephone, video and internet access services provided over fiber optic
  networks to residential customers.
 
 
   As a result of the restructuring, Level 3 owns less than 50% of each of the
outstanding shares and voting rights of each entity, and therefore accounts for
each entity using the equity method.
 
   On June 4, 1998, Cable Michigan announced that its Board of Directors had
reached a definitive agreement to sell the company to Avalon Cable for $40.50
per share in a cash-for-stock transaction. Level 3 received approximately $129
million when the transaction closed on November 6, 1998 and expects to
recognize a pre-tax gain of approximately $90 million in the fourth quarter.
 
   On September 25, 1998, Commonwealth Telephone Enterprises, Inc. ("CTCO")
announced that it was commencing a rights offering of 3.7 million shares of its
common stock. Under the terms of the offering, each stockholder received one
right for every five shares of CTCO Common Stock or CTCO Class B Common Stock
held. The rights enabled the holder to purchase CTCO Common Stock at a
subscription price of $21.25 per share. Each right also carried the right to
oversubscribe at the subscription price for the offered shares not purchased
pursuant to the initial exercise of rights.
 
   Level 3, which owned approximately 48% of CTCO prior to the rights offering,
exercised its 1.8 million rights it received with respect to the shares it
held. Messrs. Walter Scott, Jr., James Q. Crowe and David C. McCourt, members
of the Board of Directors of both Level 3 and CTCO, agreed to oversubscribe for
all the other shares offered for sale in the rights offering. The commitments
of Messrs. Scott, Crowe, McCourt and other stockholders, resulted in Level 3
maintaining its 48% ownership interest in CTCO after the rights offering.

   The Company recognizes gains from the sale, issuance and repurchase of stock
by its subsidiaries and equity method investees. During 1998, RCN issued stock
in a public offering and for certain acquisitions. The increase in the
Company's proportionate share of RCN's net assets as a result of these
transactions resulted in pre-tax gains of $4 million and $25 million to the
Company for the three months and nine months ended September 30, 1998,
respectively.
 
   On September 30, 1998, Level 3 owned approximately 48%, 48% and 41% of the
outstanding shares of Commonwealth Telephone, Cable Michigan and RCN,
respectively. The market value of the Company's investment in the three
entities on September 30, 1998, was $216 million, $116 million and $346
million, respectively.
 
7. Long Term Debt
 
   On April 28, 1998, the Company received $1.94 billion of proceeds from an
offering of $2 billion aggregate principal amount 9.125% Senior Notes Due 2008
(the "Senior Notes"). The Senior Notes are senior, unsecured obligations of the
Company, ranking pari passu with all existing and future senior unsecured
indebtedness of the Company. The Senior Notes contain certain covenants, which
among others, limit consolidated debt, dividend payments, and transactions with
affiliates. The Company is using the net proceeds of the Senior Notes in
connection with the implementation of its Business Plan to increase
substantially its information services business and to expand the range of
services it offers by building an advanced international, facilities-based
communications network based on IP technology. Debt issuance costs of $65
million have been capitalized and will be amortized over the term of the notes.
The Company capitalized $5 million of interest expense and amortized debt
issuance costs related to network construction and systems development projects
in the third quarter of 1998 and $6 million for the nine months ended September
30, 1998.
 
8. Level 3 Stock Plan
 
   Subsequent to the Split-off, the Company adopted the recognition provisions
of Statement of Financial Accounting Standards ("SFAS") No. 123, "Accounting
for Stock Based Compensation" ("SFAS No. 123")
 
                                      F-13

       NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS--(Continued)
 
when it adopted an outperform stock option program ("OSO"). Under SFAS No. 123,
the fair value of an option (as computed in accordance with accepted option
valuation models) on the date of grant is amortized over the vesting period of
the option. The recognition provisions of SFAS No. 123 are applied
prospectively upon adoption. As a result, the recognition provisions are
applied to all stock awards granted in the year of adoption and are not applied
to awards granted in previous years unless those awards are modified or settled
in cash after adoption of the recognition provisions.
 
   The OSO program was designed by the Company so that its stockholders receive
a market return on their investment before OSO holders receive any return on
their options. The Company believes that the OSO program aligns directly
management's and stockholders' interests by basing stock option value on the
Company's ability to outperform the market in general, as measured by the
Standard & Poor's ("S&P") 500 Index. Participants in the OSO program do not
realize any value from options unless the Level 3 Common Stock price
outperforms the S&P 500 Index. When the stock price gain is greater than the
corresponding gain on the S&P 500 Index, the value received for options under
the OSO plan is based on a formula involving a multiplier related to the level
by which the Level 3 Common Stock outperforms the S&P 500 Index. To the extent
that the Level 3 Common Stock outperforms the S&P 500, the value of OSOs to an
option holder may exceed the value of non-qualified stock options.
 
   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 and
consultants; that is, an entity has granted something of value to an employee
and consultants (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 and consultants should be recognized in
financial statements because nonrecognition implies that either the instruments
have no value or that they are free to employees and consultants, 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 or
professional expenses in an entity's financial statements, the expense differs
from other compensation and professional expenses in that these charges will
not be settled in cash, but rather, generally, through issuance of common
stock.
 
   The Company believes that the adoption of SFAS No. 123 will result in
material non-cash charges to operations in 1998 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 of each option estimated at the
time of its grant. The expense recognized for options granted to employees and
consultants for services performed for the three and nine months ended
September 30, 1998, was $12 million and $23 million, respectively. In addition
to the expense recognized, the Company capitalized $2 million of non-cash
compensation for employees directly involved in the construction of the IP
network and the development of the business support systems. On a pro forma
basis, adopting SFAS No. 123 would not have had a material effect on the
results of operations for the three and nine month periods in 1997.
 
 
9. Comprehensive Income
 
   In the first quarter of 1998, the Company adopted SFAS No. 130, "Reporting
Comprehensive Income". The standard requires the display and reporting of
comprehensive income which includes all changes in stockholders' equity with
the exception of additional investments by stockholders or distributions to
stockholders. Comprehensive income for the Company includes net earnings
(loss), unrealized gains (losses) on securities and foreign currency
translation adjustments, which are charged or credited to the cumulative
translation account within stockholders' equity.

10. New Accounting Pronouncements
 
   In 1997, the Financial Accounting Standards Board issued SFAS No. 131,
"Disclosures about Segments of an Enterprise and Related Information", ("SFAS
No. 131"), which changes the way public companies report information about
segments. SFAS No.131, which is based on the management approach to segment
reporting includes requirements to report selected segment information
quarterly, and entity wide disclosures about products and services, major
customers, and geographic data. This statement is effective for financial
statements for periods beginning after December 15, 1997. The Company will
reflect the adoption of SFAS No. 131 in its December 31, 1998 financial
statements.
 
   On March 4, 1998, the Accounting Standards Executive Committee ("AcSEC")
issued Statement of Position 98-1, "Accounting for the Costs of Computer
Software Developed or Obtained for Internal Use" ("SOP 98-1"). The effective
date of this pronouncement is for fiscal years beginning after December 15,
1998, however, earlier application is encouraged and the Company is accounting
for these costs in accordance with SOP 98-1 in 1998.
 
 
   On April 3, 1998, the AcSEC issued Statement of Position 98-5, "Reporting on
the Costs of Start-Up Activities", ("SOP 98-5"), which provides guidance on the
financial reporting of start-up and organization costs. It requires costs of
start-up activities and organization costs to be expensed as incurred. SOP 98-5
is effective for financial statements for fiscal years beginning after December
15, 1998. The Company expects that the charge to earnings resulting from the
adoption of SOP98-5 will not be significant relative to the Company's financial
position or results of operations.
 
   On June 15, 1998, the FASB issued Statement of Financial Accounting
Standards No. 133, "Accounting for Derivative Instruments and Hedging
Activities" ("SFAS No. 133"). SFAS No. 133 is effective for fiscal years
beginning after June 15, 1999 (January 1, 2000 for the Company). SFAS No. 133
requires that all derivative instruments be recorded on the balance sheet at
the fair value. Changes in the fair value of derivatives are recorded each
period in current earnings or other comprehensive income, depending on whether

a derivative is designated as part of a hedge transaction and, if it is, the
type of hedge transaction. The Company does not currently utilize derivative
instruments, therefore the adoption of SFAS No. 133 is not expected to have a
significant effect on the Company's results of operations or its financial
position.
 
11. Business Developments
 
   On March 23, 1998, the Company and Frontier Communications International,
Inc. ("Frontier") entered into an agreement ("Frontier Agreement") enabling the
Company to lease approximately 8,300 miles of OC-12 network capacity on
Frontier's new 13,000 mile SONET fiber optic, IP-capable network, currently
under construction for a period of up to five years. The leased network will
initially connect 15 of the larger cities across the United States. While
requiring an aggregate minimum payment of $165 million over its five-year term,
the Frontier Agreement does not impose monthly minimum consumption requirements
on the Company, allowing the Company to order, alter or terminate circuits as
it deems appropriate. The Company recognized costs in the third quarter of 1998
as portions of the network became operational.
 
   On April 2, 1998, the Company announced it had reached a definitive
agreement with Union Pacific Railroad Company ("Union Pacific") granting the
Company rights-of-way along Union Pacific's rail routes for construction of the
Company's North American intercity network. The Company expects that the Union
Pacific agreement will satisfy substantially all of its anticipated right-of-
way requirements west of the Mississippi River and approximately 50% of the
right-of-way requirements for its North American intercity network. The
agreement provides for initial fixed payments of up to $8 million to Union
Pacific upon execution of the agreement and throughout the construction period,
recurring payments in the form of cash, communications capacity, and other
communications services based on the number of conduits that are operational
and certain construction obligations of the Company to provide fiber or conduit
connections for Union Pacific at the Company's incremental cost of
construction.
 
   On June 23, 1998, the Company signed a master easement agreement with
Burlington Northern and Sante Fe Railway Company ("BNSF"). The agreement grants
Level 3 right-of-way access to BNSF rail routes in as many as 28 states, over
which to build its network. Under the easement agreement, Level 3 will make
annual payments to BNSF and provide communications capacity to BNSF for its
internal requirements. The amount of the annual payments is dependent upon the
number of conduits installed, the number of conduits with fiber, and the number
of miles of conduit installed along BNSF's route.
 
   On June 18, 1998, Level 3 selected Peter Kiewit Sons', Inc. ("Kiewit") to
build its 15,000 mile intercity communications network. The overall cost of the
project is estimated at $2 billion. Construction of the network began in the
third quarter of 1998 and is expected to be completed during the first quarter
of 2001. The contract provides that Kiewit be reimbursed for its costs relating
to all direct and indirect project level costs. In addition, Kiewit will have
the opportunity to earn an award fee that will be based on cost and speed of
construction, quality, safety and program management. The award fee will be
determined by Level 3's assessment of Kiewit's performance in each of these
areas.
 
   On July 20, 1998, Level 3 entered into a network construction cost-sharing
agreement with INTERNEXT, LLC, a subsidiary of NEXTLINK Communications, Inc.
valued at $700 million. The agreement calls for INTERNEXT to acquire the right
to use 24 fibers and certain associated facilities installed along the entire
route of Level 3's 15,000 mile intercity fiber optic network in the United
States. INTERNEXT will pay Level 3 as segments of the intercity network are
completed which will reduce the overall cost of the network to the Company.
 
   The network as provided to INTERNEXT will not include the necessary
electronics that allow the fiber to carry communications transmissions.
INTERNEXT will be restricted from selling or leasing fiber to unaffiliated

companies for the next four years. Also, under the terms of the agreement,
INTERNEXT has the right to an additional conduit for its exclusive use and to
share costs and capacity in certain future fiber cable installations in Level 3
conduits.
 
   On August 3, 1998, Level 3 and a group of 32 other global telecommunications
companies entered into an agreement to construct an undersea cable system
connecting Japan and the United States by mid-year 2000. The parties to this
agreement are investing in excess of $1 billion to build the network, of which
Level 3 is expected to contribute approximately $130 million. In addition, each
party will have joint responsibility for network oversight, maintenance and
administration.
 
   On October 14, Level 3 announced that it had signed an agreement with Global
Crossing Ltd. for trans-oceanic capacity on Global Crossing's fiber optic cable
network. The agreement, covering 25 years and valued at approximately $100
million, will provide Level 3 with as-needed dedicated capacity across the
Atlantic Ocean. Level 3 will have the option of utilizing capacity on other
segments of Global Crossing's worldwide network.
 
12. Other Matters
 
   Prior to the Split-off, as of January 1 of each year, holders of Class C
Stock had the right to convert Class C Stock into Class D Stock, subject to
certain conditions. In January 1998, holders of Class C Stock converted 2.3
million shares, with a redemption value of $122 million, into 21 million shares
of Level 3 Common Stock (formerly Class D Stock).
 
   The Company is involved in various lawsuits, claims and regulatory
proceedings incidental to its business. Management believes that any resulting
liability for legal proceedings beyond that provided should not materially
affect the Company's financial position, future results of operations or future
cash flows.

Level 3 Communications, Inc. and Subsidiaries
(formerly, Peter Kiewit Sons', Inc.)
 
We have audited the consolidated financial statements of Level 3
Communications, Inc. and Subsidiaries (formerly, Peter Kiewit Sons', Inc.) on
pages F-19 through F-54. 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
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 consolidated financial position of Level 3
Communications, Inc. and Subsidiaries as of December 27, 1997 and December 28,
1996, and the consolidated results of their operations and their cash flows for
each of the three years in the period ended December 27, 1997 in conformity
with generally accepted accounting principles.

                   Notes to Consolidated Financial Statements
 
(1) Summary of Significant Accounting Policies
 
Principles of Consolidation
 
   The consolidated financial statements include the accounts of Level 3
Communications, Inc. and subsidiaries (formerly Peter Kiewit Sons', Inc.)
("Level 3" or "the Company"), which are engaged in enterprises primarily
related to construction, coal mining, energy generation, information services,
and telecommunications. Fifty-percent-owned mining joint ventures are
consolidated on a pro rata basis. Investments in other companies in which the
Company exercises significant influence over operating and financial policies,
including construction joint ventures and energy projects, are accounted for by
the equity method. The Company accounts for its share of the operations of the
construction joint ventures on a pro rata basis in the consolidated statements
of earnings. All significant intercompany accounts and transactions have been
eliminated.
 
   In 1997, the Company agreed to sell its energy assets to CalEnergy Company,
Inc. ("CalEnergy") and to spin-off the construction business. Therefore, the
assets and liabilities and results of operations of both businesses have been
classified as discontinued operations on the consolidated balance sheet,
statements of earnings and cash flows. (See notes 2 and 3)
 
   On September 5, 1997, C-TEC Corporation ("C-TEC") announced that its board
of directors had approved the planned restructuring of C-TEC into three
publicly traded companies. The transaction was effective September 30, 1997. As
a result of the restructuring plan, the Company owns less than 50% of the
outstanding shares and voting rights of each entity, and therefore has
accounted for each entity using the equity method as of the beginning of 1997.
In accordance with Generally Accepted Accounting Principles, C-TEC's financial
position, results of operations and cash flows are consolidated in the 1996 and
1995 financial statements.
 
   The results of operations of MFS Communications Company, Inc. ("MFS"),
(which later merged into WorldCom Inc.) prior to its spin-off on September 30,
1995, have been classified as a single line item on the statements of earnings
 
   The Company invests in the portfolios of the Kiewit Mutual Fund, ("KMF"), a
registered investment company. KMF is not consolidated in the Company's
financial statements.
 
Description of Business Groups
 
   Holders of Class C Stock ("Construction & Mining Group") and Class D Stock
("Diversified Group") are stockholders of the Company. The Construction &
Mining Group ("KCG") contains the Company's traditional construction and
materials operations performed by Kiewit Construction Group Inc. The
Diversified Group through Kiewit Diversified Group, Inc. contains coal mining
properties owned by Kiewit Coal Properties Inc., energy investments, including
a 24% interest in CalEnergy and a 30% interest in CE Electric UK plc ("CE
Electric"), investments in international energy projects, information services
businesses, telecommunications companies owned by C-TEC, as well as other
assets. Corporate assets and liabilities which are not separately identified
with the ongoing operations of the Construction & Mining Group or the
Diversified Group are allocated equally between the groups.
 
Construction Contracts
 
   KCG operates generally within the United States and Canada as a general
contractor and engages in various types of construction projects for both
public and private owners. Credit risk is minimal with public (government)
owners since KCG ascertains that funds have been appropriated by the
governmental project owner prior to commencing work on public projects. Most
public contracts are subject to termination at the
 
                                      F-26

            Notes to Consolidated Financial Statements--(Continued)
 
 
(1) Summary of Significant Accounting Policies (Continued)
 
election of the government. In the event of termination, KCG is entitled to
receive the contract price on completed work and reimbursement of termination
related costs. Credit risk with private owners is minimized because of
statutory mechanics liens, which give KCG high priority in the event of lien
foreclosures following financial difficulties of private owners.
 
   The construction industry is highly competitive and lacks firms with
dominant market power. A substantial portion of KCG's business involves
construction contracts obtained through competitive bidding. The volume and
profitability of KCG's construction work depends to a significant extent upon
the general state of the economies in which it operates and the volume of work
available to contractors. KCG's construction operations could be adversely
affected by labor stoppages or shortages, adverse weather conditions, shortages
of supplies, or other governmental action.
 
   KCG recognizes revenue on long-term construction contracts and joint
ventures on the percentage-of-completion method based upon engineering
estimates of the work performed on individual contracts. Provisions for losses
are recognized on uncompleted contracts when they become known. Claims for
additional revenue are recognized in the period when allowed. It is at least
reasonably possible that engineering estimates of the work performed on
individual contracts will be revised in the near term.
 
Coal Sales Contracts
 
   Level 3's coal is sold primarily under long-term contracts with electric
utilities, which burn coal in order to generate steam to produce electricity. A
substantial portion of Level 3's coal sales were made under long-term contracts
during 1997, 1996 and 1995. The remainder of Level 3's sales are made on the
spot market where prices are substantially lower than those in the long-term
contracts. As the long-term contracts expire, a higher proportion of Level 3's
sales will occur on the spot market.
 
   The coal industry is highly competitive. Level 3 competes not only with
other domestic and foreign coal suppliers, some of whom are larger and have
greater capital resources than Level 3, but also with alternative methods of
generating electricity and alternative energy sources. Many of Level 3's
competitors are served by two railroads and, due to the competition, often
benefit from lower transportation costs than Level 3 which is served by a
single railroad. Additionally, many competitors have lower stripping ratios
than Level 3, often resulting in lower comparative costs of production.
 
   Level 3 is also required to comply with various federal, state and local
laws concerning protection of the environment. Level 3 believes its compliance
with environmental protection and land restoration laws will not affect its
competitive position since its competitors are similarly affected by such laws.
 
   Level 3 and its mining ventures have entered into various agreements with
its customers which stipulate delivery and payment terms for the sale of coal.
Prior to 1993, one of the primary customers deferred receipt of certain
commitments by purchasing undivided fractional interests in coal reserves of
Level 3 and the mining ventures. Under the agreements, revenue was recognized
when cash was received. The agreements with this customer were renegotiated in
1992. In accordance with the renegotiated agreements, there were no sales of
interests in coal reserves subsequent to January 1, 1993. Level 3 has the
obligation to deliver the coal reserves to the customer in the future if the
customer exercises its option. If the option is exercised, Level 3 presently
intends to deliver coal from unaffiliated mines. In the opinion of the
management, Level 3 has sufficient coal reserves to cover the above sales
commitments.

            Notes to Consolidated Financial Statements--(Continued)
 
(1) Summary of Significant Accounting Policies (Continued)
 
   Level 3's coal sales contracts are with several electric utility and
industrial companies. In the event that these customers do not fulfill
contractual responsibilities, Level 3 would pursue the available legal
remedies.
 
Information Services Revenue
 
   Information services revenue is primarily derived from the computer
outsourcing business and the systems integration business. Level 3 provides
outsourcing service, typically through contracts ranging from 3-5 years, to
firms that desire to focus their resources on their core businesses. Under
these contracts, Level 3 recognizes revenue in the month the service is
provided. The systems integration business helps customers define, develop and
implement cost-effective information systems. Revenue from these services is
billed on a time and materials basis or percentage of completion basis
depending on the extent of the services provided.
 
Telecommunications Revenue
 
   In 1996 and 1995 C-TEC's most significant operating groups were its local
telephone service and cable system operations. C-TEC's telephone network
access revenues are derived from net access charges, toll rates and settlement
arrangements for traffic that originates or terminates within C-TEC's local
telephone company. Revenues from telephone services and basic and premium
cable programming services are recorded in the month the service is provided.
 
   The telecommunications industry is subject to local, state and federal
regulation. Consequently, the ability of the telephone and cable groups to
generate increased volume and profits is largely dependent upon regulatory
approval to expand customer bases and increase prices.
 
   Competition for the cable group's services traditionally has come from
broadcast television, video rentals and direct broadcast satellite received on
home dishes. Future competition is expected from telephone companies.
 
   Concentration of credit risk with respect to accounts receivable are
limited due to the dispersion of customer base among geographic areas and
remedies provided by terms of contracts and statutes.
 
   As noted previously, the investment in C-TEC has been accounted for using
the equity method in 1997.
 
Depreciation and Amortization
 
   Property, plant and equipment are recorded at cost. Depreciation and
amortization for the majority of the Company's property, plant and equipment
are computed on accelerated and straight-line methods. Depletion of mineral
properties is provided primarily on an units-of-extraction basis determined in
relation to estimated reserves.
 
Intangible Assets
 
   Intangible assets primarily include amounts allocated upon purchase of
existing operations, franchises and subscriber lists. These assets are
amortized on a straight-line basis over the expected period of benefit, which
does not exceed 40 years.
 
Long Lived Assets
 
   The Company reviews the carrying amount of long lived assets 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 asset to the net carrying value of
the asset.

Reserves for Reclamation
 
   Level 3 follows the policy of providing an accrual for reclamation of mined
properties, based on the estimated cost of restoration of such properties, in
compliance with laws governing strip mining. It is at least reasonably possible
that the estimated cost of restoration will be revised in the near-term.
 
Foreign Currencies
 
   Generally, local currencies of foreign subsidiaries are the functional
currencies for financial reporting purposes. Assets and liabilities are
translated into U.S. dollars at year-end exchange rates. Revenue and expenses
are translated using average exchange rates prevailing during the year. Gains
or losses resulting from currency translation are recorded as adjustments to
stockholders' equity.
 
Subsidiary and Investee Stock Activity
 
   The Company recognizes gains and losses from the sale, issuance and
repurchase of stock by its subsidiaries.
 
Earnings Per Share
 
   In 1997, the Company adopted Statement of Financial Accounting Standards
("SFAS") No. 128, "Earnings Per Share". The Statement establishes standards for
computing and presenting earnings per share and requires the restatement of
prior per share data presented. Basic earnings per share have been computed
using the weighted average number of shares during each period. Diluted
earnings per share is computed by including stock options and convertible
debentures considered to be dilutive common stock equivalents.
 
   Potentially dilutive stock options are calculated in accordance with the
treasury stock method which assumes that proceeds from the exercise of all
options are used to repurchase common stock at the average market value. The
number of shares remaining after the proceeds are exhausted represent the
potentially dilutive effect of the options. The potentially dilutive
convertible debentures are calculated in accordance with the "if converted"
method. This method assumes that the after-tax interest expense associated with
the debentures is an addition to income and the debentures are converted into
equity with the resulting common shares being aggregated with the weighted
average shares outstanding.
 
   The following details the earnings per share calculations for Class C Stock
and Class D Stock:

 Stock Dividend
 
   Effective December 26, 1997, the Company's Board of Directors approved a
dividend of four shares of Class D Stock for every one share of Class D Stock
held. All share information and per share data have been restated to reflect
this dividend.
 
 Income Taxes
 
   Deferred income taxes are provided for the temporary differences between the
financial reporting basis and tax basis of the Company's assets and liabilities
using enacted tax rates in effect for the year in which the differences are
expected to reverse.
 
 Use of Estimates
 
   The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

 Recently Issued Accounting Pronouncements
 
   In June 1997, the Financial Accounting Standards Board ("FASB") issued SFAS
No. 130, "Reporting Comprehensive Income", which requires that changes in
comprehensive income be shown in a financial statement that is displayed with
the same prominence as other financial statements.
 
   Also in 1997, the FASB issued SFAS No. 131, "Disclosures about Segments of
an Enterprise and Related Information", which changes the way public companies
report information about segments. SFAS No. 131, which is based on the
management approach to segment reporting includes requirements to report
selected segment information quarterly, and entity wide disclosures about
products and services, major customers, and geographic data.
 
   These statements are effective for financial statements for periods
beginning after December 15, 1997. Management does not expect adoption of these
statements to materially affect the Company's financial statements.
 
 Reclassifications
 
   Where appropriate, items within the consolidated financial statements and
notes thereto have been reclassified from previous years to conform to current
year presentation.
 
 Fiscal Year
 
   The Company's fiscal year ends on the last Saturday in December. There were
52 weeks in fiscal years 1997, 1996 and 1995.
 
(2) Reorganization
 
   In October 1996, the Company's Board of Directors directed the Company's
management to pursue a listing of Class D Stock as a way to address certain
issues created by the Company's two-class capital stock structure and the need
to attract and retain the best management for the Company's businesses. During
the course of its examination of the consequences of a listing of Class D
Stock, management concluded that a listing of Class D Stock would not
adequately address these issues, and instead began to study a separation of the
Construction & Mining Group and the Diversified Group. At the regular meeting
of the Board on July 23, 1997, management submitted to the Board for
consideration a proposal for separation of the Construction & Mining Group and
Diversified Group through a spin-off of the Construction & Mining Group ("the
Transaction"). At a special meeting on August 14, 1997, the Board approved the
Transaction.
 
   The separation of the Construction & Mining Group and the Diversified Group
was contingent upon a number of conditions, including the favorable
ratification by a majority of both Class C and Class D shareholders and the
receipt by the Company of an Internal Revenue Service ruling or other assurance
acceptable to the Board that the separation would be tax-free to U.S.
shareholders. On December 8, 1997, the Company's Class C and Class D
shareholders approved the transaction and on March 5, 1998 the Company received
a favorable ruling from the Internal Revenue Service. The Transaction is
anticipated to be effective on March 31, 1998. As a result of these events the
Company has reflected the financial position and results of operations of the
Construction & Mining Group as discontinued operations on the consolidated
balance sheets and consolidated statements of earnings for all periods
presented. The activities of the Construction & Mining Group have been removed
from the statements of cash flows.

   Immediately prior to the spin-off of the Construction & Mining Group, the
Company will recognize a gain equal to the difference between the carrying
value of the Construction & Mining Group and its fair value. The Company will
then reflect the fair value of Construction & Mining Group as a dividend to
shareholders. See Note 17. See also "Certain Transactions and Relationships"
for a discussion of the Separation Agreement, Tax Sharing Agreement and Mine
Management Agreement entered into by Level 3 and the Construction & Mining
Group in order to implement the spin-off.
 
   Level 3 has recently decided to substantially increase its emphasis on and
resources to its information services business. Pursuant to the plan, Level 3
intends to expand substantially its current information services business,
through the expansion of its existing business and the creation, through a
combination of construction, leasing and purchase of facilities and other
assets, of a substantial facilities-based internet communications network (the
"Expansion Plan").
 
   Using the network, Level 3 intends to provide (a) a range of internet access
services at varying capacity levels and, as technology development allows, at
specified levels of quality of service and security and (b) a number of
business oriented communications services which may include fax service, which
are transmitted in part over private or limited access Transmission Control
Protocol/Internet Protocol ("TCP/IP") networks and are offered at lower prices
than public telephone network-based fax service, and voice message storing and
forwarding over the same TCP/IP-based networks.
 
(3) Discontinued Energy Operations
 
   In connection with the Expansion Plan, Level 3 expects to devote
substantially more management time and capital resources to its information
services business with a view to making the information services business, over
time, the principal business of Level 3. In that respect, the management is
conducting a comprehensive review of the existing Level 3 businesses to
determine how those businesses will complement Level 3's focus on information
services. If it is decided that an existing business is not compatible with the
information services business and if a suitable buyer can be found, Level 3 may
dispose of that business.

(3) Discontinued Energy Operations (Continued)
 
   On September 10, 1997, Level 3 and CalEnergy entered into an agreement
whereby CalEnergy contracted to purchase Level 3's energy investments for
$1,155 million, subject to adjustments. These energy investments include
approximately 20.2 million shares of CalEnergy common stock (assuming the
exercise of 1 million options held by Level 3), Level 3's 30% ownership
interest in CE Electric and Level 3's investments, made jointly with CalEnergy,
in international power projects in Indonesia and the Philippines. The
transaction was subject to the satisfactory completion of certain provisions of
the agreement and closed on January 2, 1998. These assets comprised the energy
segment of Level 3. Therefore, the Company has reflected these assets, the
earnings and losses attributable to these assets, and the related cash flow
items as discontinued operations on the balance sheets, statements of earnings
and cash flows for all periods presented.
 
   In order to fund the purchase of these assets, CalEnergy sold, in October
1997, approximately 19.1 million shares of its common stock at a price of
$37.875 per share. This sale reduced Level 3's ownership in CalEnergy to
approximately 24% but increased its proportionate share of CalEnergy's equity.
It is the Company's policy to recognize gains or losses on the sale of stock by
its investees. Level 3 recognized an after-tax gain of approximately $44
million from transactions in CalEnergy stock in the fourth quarter of 1997.
 
   The Agreement with CalEnergy included a provision whereby CalEnergy and
Level 3 shared equally any proceeds from the offering above or below a
specified amount. The offering was conducted at a price above that provided in
the agreement and therefore, Level 3 received additional proceeds of $16
million at the time of closing.
 
   Level 3 expects to recognize an after-tax gain on the disposition of its
energy assets in 1998 of approximately $324 million. The after-tax proceeds
from the transaction of approximately $967 million will be used to fund in part
the Expansion Plan.

   In December 1996, CE Electric, which is 70% owned by CalEnergy and 30% owned
by Level 3, acquired majority ownership of the outstanding ordinary share
capital of Northern Electric, plc. pursuant to a tender offer (the "Tender
Offer") commenced in the United Kingdom by CE Electric in November 1996. As of
March 1997, CE Electric effectively owned 100% of Northern's ordinary shares.
 
   As of December 27, 1997, CalEnergy and Level 3 had contributed to CE
Electric approximately $410 million and $176 million, respectively, of the
approximately $1.3 billion required to acquire all of Northern's ordinary and
preference shares in connection with the Tender Offer. The remaining funds
necessary to consummate the Tender Offer were provided by a term loan and a
revolving facility agreement obtained by CE Electric. Level 3 has not
guaranteed, and is not otherwise subject to recourse for, amounts borrowed
under these facilities.
 
   On July 2, 1997, the Labour Party in the United Kingdom announced the
details of its proposed "Windfall Tax" to be levied against privatized British
utilities. This one-time tax is 23% of the difference between the

value of Northern Electric, plc. at the time of privatization and the utility's
current value based on profits over a period of up to four years. CE Electric
recorded an extraordinary charge of approximately $194 million when the tax was
enacted in July 1997. The total after-tax impact to Level 3 directly through
its investment in CE Electric and indirectly through its interest in CalEnergy,
was $63 million.

   CE Electric's 1995 and 1996 operating results prior to the acquisition were
not significant relative to Level 3's results after giving effect to certain
pro forma adjustments related to the acquisitions, primarily increased
amortization and interest expense.
 
   In 1993, Level 3 and CalEnergy formed a venture to develop power projects
outside of the United States. Since 1993, construction has begun on the
Mahanagdong, Casecnan and Dieng power projects. The Mahanagdong project is a

Casecnan project is a combined irrigation and 150 MW hydroelectric power
generation facility located on the island of Luzon in the Philippines. Dieng
Unit I is a 55 MW geothermal facility on the Indonesian island of Java. An
additional five units are expected to be constructed on a modular basis at the
Dieng site, as geothermal resources are developed. In June 1997, Level 3 and
CalEnergy closed a $400 million revolving credit facility to finance the
development and construction of the remaining Indonesian projects. The credit
facility is collateralized by the Indonesian assets and is nonrecourse to Level
3.
 
   Generally, costs associated with the development, financing and construction
of the international energy projects have been capitalized by each of the
projects and will be amortized over the life of each project.
 
   The following is summarized financial information for the international
energy projects:

on the unused funds prior to payment of construction costs resulted in a loss
to the venture of $12 million in 1997 and 1996. Level 3's share of these losses
were $6 million in each year. The Mahanagdong facility commenced operation in
July, 1997. Level 3's proportionate share of the earnings attributable to
Mahanagdong was $7 million 1997. No income or losses were incurred by the
international projects in 1995. In addition to the equity earnings and losses,
Level 3 has project development and insurance expenses, and received management
fee income related to the international projects in all years.
 
   In late 1995, a Level 3 and CalEnergy venture, CE Casecnan Water and Energy
Company, Inc. ("CE Casecnan") closed financing and commenced construction of a
$495 million irrigation and hydroelectric power project located on the
Philippine island of Luzon. Level 3 and CalEnergy each made $62 million of
equity contributions to the project.
 
   The CE Casecnan project was being constructed on a joint and several basis
by Hanbo Corporation and Hanbo Engineering & Construction Co. Ltd. On May 7,
1997, CE Casecnan announced that it had terminated the Hanbo Contract. In
connection with the contract termination, CE Casecnan made a $79 million draw
request under the letter of credit issued by Korea First Bank ("KFB") to pay
for certain transition costs and other damages under the Hanbo Contract. KFB
failed to honor the draw request; the matter is being litigated. If KFB would
not be required to honor its obligations under the letter of credit, such
action may have a material adverse effect on the CE Casecnan project. Level 3
does not expect the outcome of the litigation to affect its financial position
due to the transaction with CalEnergy.
 
(4) MFS Spin-off
 
   In September 1995, the Company's Board of Directors approved a plan to make
a tax-free distribution of its entire ownership interest in MFS to the Class D
stockholders (the "Spin-off") effective on September 30, 1995. Shares were
distributed on the basis of approximately .348 shares of MFS Common Stock and
approximately .130 shares of MFS Preferred Stock for each share of outstanding
Class D Stock.
 
   The net investment in MFS distributed on September 30, 1995 was
approximately $399 million.
 
   Operating results of MFS through September 30, 1995 are summarized as
follows:

   Included in the income tax benefit on the statement of earnings for the year
ended December 30, 1995, is $93 million of tax benefits from the reversal of
certain deferred tax liabilities recognized on gains from previous MFS stock
transactions that were not taxed due to the Spin-off.
 
(5) Gain on Subsidiary's Stock Transactions, net
 
   Stock issuances by MFS for acquisitions and employee stock options, reduced
Level 3's ownership in MFS prior to the Spin-off in 1995 to 66% from 67% in
1994. As a result, Level 3 recognized a gain of $3 million in 1995 representing
the increase in Level 3's proportionate share of MFS' equity. Deferred income
taxes had been established on this gain prior to the Spin-off.

(6) Disclosures about Fair Value of Financial Instruments
 
   The following methods and assumptions were used to determine classification
and fair values of financial instruments:
 
 Cash and Cash Equivalents
 
   Cash equivalents generally consist of funds invested in the Kiewit Mutual
Fund-Money Market Portfolio and highly liquid instruments purchased with an
original maturity of three months or less. The securities are stated at cost,
which approximates fair value.
 
 Marketable Securities, Restricted Securities and Non-current Investments
 
   Level 3 has classified all marketable securities, restricted securities and
marketable non-current investments not accounted for under the equity method as
available-for-sale. Restricted securities primarily include investments in
various portfolios of the Kiewit Mutual Fund that are restricted to fund
certain reclamation liabilities of its coal mining ventures. Due to the
anticipated increase in capital expenditures, Level 3 has reclassified its
investments in marketable equity securities from non-current to current in
1997. The amortized cost of the securities used in computing unrealized and
realized gains and losses is determined by specific identification. Fair values
are estimated based on quoted market prices for the securities on hand or for
similar investments. Net unrealized holding gains and losses are reported as a
separate component of stockholders' equity, net of tax.

   On September 5, 1997, C-TEC announced that its board of directors had
approved the planned restructuring of C-TEC into three publicly traded
companies effective September 30, 1997. Under the terms of the restructuring C-
TEC shareholders received stock in the following companies:
 
  . Commonwealth Telephone Enterprises, Inc., containing the local telephone
    group and related engineering business;
 
  . Cable Michigan, Inc., containing the cable television operations in
    Michigan; and
 
  . RCN Corporation, Inc., which consists of RCN Telecom Services; C-TEC's
    existing cable systems in the Boston-Washington, D.C. corridor; and the
    investment in Megacable S.A. de C.V., a cable operator in Mexico. RCN
    Telecom Services is a provider of packaged local and long distance
    telephone, video, and internet access services provided over fiber optic
    networks to residential customers in Boston, New York City and

   As a result of the restructuring, Level 3 owns less than 50% of the
outstanding shares and voting rights of each entity, and therefore accounts for
each entity using the equity method as of the beginning of 1997. C-TEC's
financial position, results of operations and cash flows are consolidated in
the 1996 and 1995 consolidated financial statements.
 
   The following is summarized financial information of the three entities
created as a result of the C-TEC restructuring:

 CPTC:
 
   In August 1996, CPTC converted its construction financing note into a term
note with a consortium of banks ("Bank Debt"). The interest rate on the Bank
Debt is based on LIBOR plus a varying rate with interest payable quarterly.
Upon completion of the SR91 toll road, CPTC entered into an interest rate swap
arrangement with the same parties. The swap expires in January 2004 and fixes
the interest rate on the Bank Debt from 9.21% to 9.71% during the term of the
swap agreement.
 
   The institutional note is with Connecticut General Life Insurance Company, a
subsidiary of CIGNA Corporation. The note converted into a term loan upon
completion of the SR91 toll road.
 
   Substantially all the assets of CPTC and the partners' equity interest in

(9) Long-Term Debt (Continued)
 
   In July 1996, CPTC borrowed from the partners $2 million to facilitate the
completion of the project. In 1997, CPTC borrowed an additional $4 million from
the partners in order to comply with equity maintenance provisions of the
contracts with the State of California and its lenders. The debt is generally
subordinated to all other debt of CPTC. Interest on the subordinated debt
compounds annually at 9.5% and is payable only as CPTC generates excess cash
flows.
 
   CPTC capitalized interest of $-- million, $5 million and $7 million in 1997,
1996 and 1995.
 
 Other:
 
   In June 1997, a mortgage with Metropolitan Life was established. The
Pavilion Towers building in Aurora, Colorado collateralizes this debt.
 
   Scheduled maturities of long-term debt through 2002 are as follows (in
millions): 1998--$3; 1999--$6; 2000--$5; 2001--$6 and $8 in 2002.

(12) Class D Stock Plan
 
   In December 1997, stockholders approved amendments to the 1995 Class D Stock
Plan (the "Plan"). The amended plan, among other things, increases the number
of shares reserved for issuance upon the exercise of stock based awards to
35,000,000, increases the maximum number of options granted to any one
participant to 5,000,000, provides for the acceleration of vesting in the event
of a change in control, allows for the grant of stock based awards to directors
of Level 3 and other persons providing services to Level 3, and allows for the
grant of nonqualified stock options with an exercise price less than the fair
market value of Class D Stock.
 
   In December 1997, Level 3 converted both option and stock appreciation
rights plans of a subsidiary, to the Class D Stock plan. This conversion
resulted in the issuance of 3.7 million options to purchase Class D Stock at $9
per share. Level 3 recognized an expense, and a corresponding increase in
equity, as a result of the transaction. This increase in equity and the
conversion of the stock appreciation rights liability to equity are reflected
as option activity in the Statement of Changes in Stockholders' Equity. The
options vest over three years and expire in December 2002.
 
   Through 1997, Level 3 elected to adopt only the required disclosure
provisions and not the optional expense recognition provisions under SFAS No.
123 "Accounting for Stock Based Compensation", which established a fair value
based method of accounting for stock options and other equity instruments. The
fair value of the options outstanding was calculated using the Black-Scholes
method using risk-free interest rates ranging from 5.5% to 6.77% and expected
lives of 75% of the total life of the option. Level 3 used an expected
volatility rate of 0%, which is allowed for private entities under SFAS No.
123. Once Level 3's stock is listed, volatility factors will be incorporated in
determining fair value. Level 3's net income and earnings per share for 1997
and 1996 would have been reduced to the pro forma amounts shown below had SFAS
No. 123 been applied.

(c)Reflect fair value gain on the distribution of the Construction & Mining

(d)Reflect spin-off of the Construction & Mining Group.
 
(18) Other Matters
 
   In connection with the sale of approximately 10 million Class D shares to
employees in 1997, the Company has retained the right to purchase the relevant
Class D shares at the then current Class D Stock price if the Transaction is
definitively abandoned by formal action of the Company's Board or the employees
voluntarily terminate their employment on various dates prior to January 1,
1999.
 
   In May 1995, the lawsuit titled Whitney Benefits, Inc. and Peter Kiewit
Sons' Co. v. The United States was settled. In 1983, plaintiffs alleged that
the enactment of the Surface Mining Control and Reclamation Act of 1977 had
prevented the mining of their Wyoming coal deposit and constituted a government
taking without just compensation. In settlement of all claims, plaintiffs
agreed to deed the coal deposits to the government and the government agreed to
pay plaintiffs $200 million, of which Peter Kiewit Sons' Co., a Level 3
subsidiary, received approximately $135 million in June 1995 and recorded it in
other income on the statements of earnings.

            Notes to Consolidated Financial Statements--(Continued)
 
 
(18) Other Matters (Continued)
 
   The Company is involved in various other lawsuits, 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, future results of operations or future cash flows.
 
   Level 3 leases various buildings and equipment under both operating and
capital leases. Minimum rental payments on buildings and equipment subject to
noncancelable operating leases during the next 7 years aggregate $29 million.
 
   It is customary in Level 3's industries to use various financial instruments
in the normal course of business. These instruments include items such as
letters of credit. Letters of credit are conditional commitments issued on
behalf of Level 3 in accordance with specified terms and conditions. As of
December 27, 1997, Level 3 had outstanding letters of credit of approximately
$22 million.
 
(19) Subsequent Events
 
   In January 1998, approximately 2.3 million shares of Class C Stock, with a
redemption value of $122 million, were converted into 10.5 million shares of
Class D Stock.
 
   In March 1998, the Company announced that its Class D Stock will begin
trading on April 1 on the Nasdaq National Market under the symbol "LVLT". The
Nasdaq listing will follow the separation of the Diversified Group and the
Construction Group, which is expected to be completed on March 31, 1998. In
connection with the separation, the Company's construction subsidiary will be
renamed "Peter Kiewit Sons', Inc." and Class D stock will become the common
stock of Level 3 Communications, Inc.
 
   The Company's certificate of incorporation gives stockholders the right to
exchange their Class C Stock for Class D Stock under a set conversion formula.
That right will be eliminated as a result of the separation of the Diversified
Group and the Construction Group. To replace that conversion right, Class C
stockholders received 6.5 million shares of a new Class R stock in January,
1998, which is convertible into Class D Stock in accordance with terms ratified
by stockholders in December 1997.
 
   The Company's Board of Directors has approved in principle a plan to force
conversion of all shares of Class R stock outstanding. Due to certain
provisions of the Class R stock, conversion will not be forced prior to May
1998, and the final decision to force conversion would be made by Level 3's
Board of Directors at that time. Level 3's Board may choose not to force
conversion if it were to decide that conversion is not in the best interests of
Level 3 stockholders. If, as currently anticipated, Level 3's Board determines
to force conversion of the Class R stock on or before June 30, 1998, certain
adjustments will be made to the cost sharing and risk allocation provisions of
the separation agreement between Level 3 and the Construction business.
 
   If Level 3's Board of Directors determines to force conversion of the Class
R stock, each share of Class R stock will be convertible into $25 worth of
Level 3 (Class D) common stock, based upon the average trading price of the
Level 3 common stock on the Nasdaq National Market for the last fifteen trading
days of the month prior to the determination by the Board of Directors to force
conversion. When the spin-off occurs, Level 3 will increase paid in capital and
reduce retained earnings by the fair value of the Class R shares.

                                  The Company
 
   We engage in the information services, communications and coal mining
businesses through ownership of operating subsidiaries and substantial equity
positions in public companies. In late 1997, we announced a business plan to
increase substantially our information services business and to expand the
range of services we offer. We are implementing our business plan by building
an advanced communications network based on internet protocol technology.
 
   Since late 1997, we have substantially increased the emphasis we place on
and the resources devoted to our communications and information services
business. We intend to become a facilities-based provider of a broad range of
integrated communications services. A facilities-based provider is one that
owns or leases a substantial portion of the plant, property and equipment
necessary to provide its services. To reach this goal, we plan to expand
substantially the business of our subsidiary PKS Information Services, Inc. and
to create our communications network. We will create this network through a
combination of construction, purchase and leasing of facilities and other
assets. We are designing our network based on internet protocol technology in
order to leverage the efficiencies of this technology to provide lower cost
communications services.
 
   Our network will combine both local and long distance networks and will
connect customers end-to-end across the U.S. and in Europe and Asia. We expect
to complete the U.S. intercity portion of the network during the first quarter
of 2001. In the meantime, we have leased a national network over which we began
to offer services in the third quarter of 1998. We intend to provide a full
range of communications services--including local, long distance, international
and internet services.
 
   Our principal executive offices are located at 3555 Farnam Street, Omaha,
Nebraska 68131 and our telephone number is (402) 536-3677. We are constructing
a new headquarters outside of Denver, Colorado, which we expect to begin
occupying during the summer of 1999.
 
        Ratio of Earnings to Fixed Charges and Preferred Stock Dividends
 
   The ratio of earnings to fixed charges for each of the periods indicated is
as follows:
 
<TABLE>
<CAPTION>
     Nine Months Ended
       September 30,        Fiscal Year Ended
     --------------------------------------------
       1998      1997      1997      1996      1995      1994      1993
     --------  --------  --------  --------  --------  --------  --------
     <S>       <C>       <C>       <C>       <C>       <C>       <C>
         --      7.29      5.73      3.87        --        --      20.94
</TABLE>
 
   For this ratio, earnings consist of earnings (loss) before income taxes,
minority interest and discontinued operations plus fixed charges excluding
capitalized interest. Fixed charges consist of interest expensed and
capitalized, plus the portion of rent expense under operating leases deemed by
us to be representative of the interest factor, plus, prior to September 30,
1995, preferred stock dividends on preferred stock of its former subsidiary,
MFS Communications Company, Inc. We had deficiencies of earnings to fixed
charges of $106 million for the nine months ended September 30, 1998, $32
million for 1995 and $42 million for 1994.
 
                            Application of Proceeds
 
   Unless the applicable prospectus supplement states otherwise, the net
proceeds from the sale of the offered securities will be used for working
capital, capital expenditures, acquisitions and other general corporate
purposes. Until we use the net proceeds in this manner, we may temporarily use
them to make short-term investments or reduce short-term borrowings.

                         Description of Debt Securities
 
   This section describes the general terms and provisions of the debt
securities. The applicable prospectus supplement will describe the specific
terms of the debt securities offered through that prospectus supplement as well
as any general terms described in this section that will not apply to those
debt securities.
 
   The debt securities will be our direct unsecured general obligations and may
include debentures, notes, bonds and/or other evidences of indebtedness. The
debt securities will be either senior debt securities or subordinated debt
securities. The debt securities will be issued under one or more separate
indentures between us and IBJ Whitehall Bank & Trust Company, as trustee.
Senior debt securities will be issued under a senior indenture, and
subordinated debt securities will be issued under a subordinated indenture.
Together, the senior indentures and the subordinated indentures are called
indentures.
 
   We have summarized selected provisions of the indentures below. The summary
is not complete. We have also filed the forms of the indentures as exhibits to
the registration statement. You should read the indentures for provisions that
may be important to you before you buy any debt securities.
 
General terms of debt securities
 
   The debt securities issued under each indenture may be issued without limit
as to aggregate principal amount, in one or more series. Each indenture
provides that there may be more than one trustee under the indenture, each with
respect to one or more series of debt securities. Any trustee under either
indenture may resign or be removed with respect to one or more series of debt
securities issued under that indenture, and a successor trustee may be
appointed to act with respect to that series.
 
   If two or more persons are acting as trustee with respect to different
series of debt securities issued under the same indenture, each of those
trustees will be a trustee of a trust under that indenture separate and apart
from the trust administered by any other trustee. In that case, except as
otherwise indicated in this prospectus, any action described in this prospectus
to be taken by the trustee may be taken by each of those trustees only with
respect to the one or more series of debt securities for which it is trustee.
 
   A prospectus supplement relating to a series of debt securities being
offered will include specific terms relating to the offering and that series.
These terms will contain some or all of the following:
 
  .  the title of the debt securities;
 
  .  any limit on the aggregate principal amount of the debt securities;
 
  .  the purchase price of the debt securities, expressed as a percentage of
     the principal amount;
 
  .  the date or dates on which the principal of and any premium on the debt
     securities will be payable or the method for determining the date or
     dates;
 
  .  if the debt securities will bear interest, the interest rate or rates or
     the method by which the rate or rates will be determined;
 
  .  if the debt securities will bear interest, the date or dates from which
     any interest will accrue, the interest payment dates on which any
     interest will be payable, the record dates for those interest payment
     dates and the basis upon which interest shall be calculated if other
     than that of a 360 day year of twelve 30-day months;
 
  .  the place or places where payments on the debt securities will be made
     and the debt securities may be surrendered for registration of transfer
     or exchange;
 
                                       3
<PAGE>
 
  .  if we will have the option to redeem all or any portion of the debt
     securities, the terms and conditions upon which the debt securities may
     be redeemed;
 
  .  the terms and conditions of any sinking fund or other similar provisions
     obligating us or permitting a holder to require us to redeem or purchase
     all or any portion of the debt securities prior to final maturity;
 
  .  the currency or currencies in which the debt securities are denominated
     and payable if other than U.S. dollars;
 
  .  whether the amount of any payments on the debt securities may be
     determined with reference to an index, formula or other method and the
     manner in which such amounts are to be determined;
 
  .  any additions or changes to the events of default in the respective
     indentures;
 
  .  any additions or changes with respect to the other covenants in the
     respective indentures;
 
  .  the terms and conditions, if any, upon which the debt securities may be
     convertible into common stock or preferred stock;
 
  .  whether the debt securities will be issued in certificated or book-entry
     form;
 
  .  whether the debt securities will be in registered or bearer form and, if
     in registered form, the denominations of the debt securities if other
     than $1,000 and multiples of $1,000;
 
  .  the applicability of the defeasance and covenant defeasance provisions
     of the applicable indenture; and
 
  .  any other terms of the debt securities consistent with the provisions of
     the applicable indenture.
 
   Debt securities may be issued under the indentures as original issue
discount securities to be offered and sold at a substantial discount from their
stated principal amount. Special U.S. federal income tax, accounting and other
considerations applicable to original issue discount securities will be
described in the applicable prospectus supplement.
 
   Unless otherwise provided with respect to a series of debt securities, the
debt securities will be issued only in registered form, without coupons, in
denominations of $1,000 and multiples of $1,000.
 
Certificated securities
 
   Except as otherwise stated in the applicable prospectus supplement, debt
securities will not be issued in certificated form. If, however, debt
securities are to be issued in certificated form, no service charge will be
made for any transfer or exchange of any of those debt securities. We may
require payment of a sum sufficient to cover any tax or other governmental
charge payable in connection with the transfer or exchange of those debt
securities.
 
Book-entry debt securities
 
   The debt securities of a series may be issued in whole or in part in the
form of one or more global securities that will be deposited with the
depositary identified in the applicable prospectus supplement. Unless it is
exchanged in whole or in part for debt securities in definitive form, a global
security may not be transferred. However, transfers of the whole security
between the depositary for that global security and its nominee or their
respective successors are permitted.
 
                                       4
<PAGE>
 
   Unless otherwise stated, The Depository Trust Company, New York, New York
will act as depositary for each series of global securities. Beneficial
interests in global securities will be shown on, and transfers of global
securities will be effected only through, records maintained by DTC and its
participants.
 
   DTC has provided the following information to us. DTC is a:
 
  .  limited-purpose trust company organized under the New York Banking Law;
 
  .  a banking organization within the meaning of the New York Banking Law;
 
  .  a member of the U.S. Federal Reserve System;
 
  .  a clearing corporation within the meaning of the New York Uniform
     Commercial Code; and
 
  .  a clearing agency registered under the provisions of Section 17A of the
     Securities Exchange Act.
 
DTC holds securities that its direct participants deposit with DTC. DTC also
facilitates the settlement among direct participants of securities
transactions, in deposited securities through electronic computerized book-
entry changes in the direct participant's accounts. This eliminates the need
for physical movement of securities certificates. Direct participants include
securities brokers and dealers, banks, trust companies, clearing corporations
and certain other organizations. DTC is owned by a number of its direct
participants and by the New York Stock Exchange, Inc., the American Stock
Exchange, Inc. and the National Association of Securities Dealers, Inc. Access
to DTC's book-entry system is also available to indirect participants such as
securities brokers and dealers, banks and trust companies that clear through or
maintain a custodial relationship with a direct participant. The rules
applicable to DTC and its direct and indirect participants are on file with the
SEC.
 
   Principal and interest payments on global securities registered in the name
of DTC's nominee will be made in immediately available funds to DTC's nominee
as the registered owner of the global securities. We and the trustee will treat
DTC's nominee as the owner of the global securities for all other purposes as
well. Accordingly, we, the trustee and any paying agent will have no direct
responsibility or liability to pay amounts due on the global securities to
owners of beneficial interests in the global securities. It is DTC's current
practice, upon receipt of any payment of principal or interest, to credit
direct participants' accounts on the payment date according to their respective
holdings of beneficial interests in the global securities. These payments will
be the responsibility of the direct and indirect participants and not of DTC,
the trustee or us.
 
   Debt securities represented by a global security will be exchangeable for
debt securities in definitive form of like amount and terms in authorized
denominations only if:
 
  .  DTC notifies us that it is unwilling or unable to continue as
     depositary;
 
  .  DTC ceases to be a registered clearing agency and a successor depositary
     is not appointed by us within 90 days; or
 
  .  we determine not to require all of the debt securities of a series to be
     represented by a global security and notify the trustee of our decision.
 
Merger
 
   We generally may consolidate with, or sell, lease or convey all or
substantially all of our assets to, or merge with or into, any other
corporation if:
 
  .  we are the continuing corporation; or
 
  .  we are not the continuing corporation, the successor corporation,
     expressly assumes all payments on all the debt securities and the
     performance and observance of all the covenants and conditions of the
     applicable indenture; and
 
                                       5
<PAGE>
 
  .  neither we nor the successor corporation is in default immediately after
     the transaction under the applicable indenture.
 
Events of default, notice and waiver
 
   Senior indenture. The senior indenture provides that the following are
events of default with respect to any series of senior debt securities:
 
  .  default for 30 days in the payment of any interest on any debt security
     of that series;
 
  .  default in the payment of the principal of or premium, if any, on any
     debt security of that series at its maturity;
 
  .  default in making a sinking fund payment required for any debt security
     of that series;
 
  .  default in the performance of any of our other covenants in the senior
     indenture that continues for 60 days after written notice, other than
     default in a covenant included in the senior indenture solely for the
     benefit of another series of senior debt securities;
 
  .  the acceleration of the maturity of more than $25,000,000 in the
     aggregate of any of our other indebtedness, where that indebtedness is
     not discharged or that acceleration is not rescinded or annulled;
 
  .  certain events of bankruptcy, insolvency or reorganization of us or our
     property; and
 
  .  any other event of default provided with respect to a particular series
     of debt securities.
 
   The senior trustee generally may withhold notice to the holders of any
series of debt securities of any default with respect to that series if it
considers the withholding to be in the interest of those holders. However, the
senior trustee may not withhold notice of any default in the payment of the
principal of, or premium, if any, or interest on any debt security of that
series or in the payment of any sinking fund installment in respect of any debt
security of that series.
 
   If an event of default with respect to any series of senior debt securities
occurs and is continuing, the senior trustee or the holders of not less than
25% in principal amount of the outstanding debt securities of that series may
declare the principal amount of all of the debt securities of that series
immediately due and payable. Subject to certain conditions, the holders of a
majority in principal amount of outstanding debt securities of that series may
rescind and annul that acceleration. However, they may only do so if all events
of default, other than the non-payment of accelerated principal or specified
portion of accelerated principal, with respect to debt securities of that
series have been cured or waived.
 
   Holders of a majority in principal amount of any series of outstanding
senior debt securities may, subject to some limitations, waive any past default
with respect to that series and the consequences of the default. The prospectus
supplement relating to any series of senior debt securities which are original
issue discount securities will describe the particular provisions relating to
acceleration of a portion of the principal amount of those original issue
discount securities upon the occurrence and continuation of an event of
default. Within 120 days after the close of each fiscal year, we must file with
the senior trustee a statement, signed by specified of our officers, stating
whether those officers have knowledge of any default under the senior
indenture.
 
   Except with respect to its duties in case of default, the senior trustee is
not obligated to exercise any of its rights or powers at the request or
direction of any holders of any series of outstanding senior debt securities,
unless those holders have offered the senior trustee reasonable security or
indemnity. Subject to those indemnification provisions and limitations
contained in the senior indenture, the holders of a majority in principal
amount of any series of the outstanding debt securities issued thereunder may
direct any proceeding for any remedy available to the senior trustee, or the
exercising of any of the senior trustee's trusts or powers.
 
                                       6

   Subordinated indenture. The subordinated indenture provides that the
following are events of default with respect to any series of subordinated debt
securities:
 
  .  default for 30 days in the payment of any interest on any debt security
     of that series;
 
  .  default in the payment of the principal of or premium, if any, on any
     debt security of that series at its maturity;
 
  .  default in making a sinking fund payment required for any debt security
     of that series;
 
  .  any default in the performance of any of our other covenants in the
     subordinated indenture that continues for 60 days after written notice,
     other than default in a covenant included in the subordinated indenture
     solely for the benefit of another series of subordinated debt
     securities;
 
 
  .  the acceleration of more than $25,000,000, where that indebtedness is
     not discharged or that acceleration is not rescinded or annulled;
 
  .  certain events relating to the bankruptcy, insolvency or reorganization
     of us or our property; and
 
  .  any other event of default provided with respect to a particular series
     of debt securities.
 
   The subordinated trustee generally may withhold notice to the holders of any
series of subordinated debt securities of any default with respect to that
series if it considers the withholding to be in the interest of the holders.
However, the subordinated trustee may not withhold notice of any default in the
payment of the principal of or premium, if any or interest on any debt security
of that series or in the payment of any sinking fund installment in respect of
any debt security of that series.
 
   If an event of default with respect to any series of subordinated debt
securities occurs and is continuing, the subordinated trustee or the holders of
not less than 25% in principal amount of the outstanding debt securities of
that series may declare the principal amount of all of the debt securities of
that series immediately due and payable. Subject to certain conditions, the
holders of a majority in principal amount of outstanding debt securities of
that series may rescind and annul that acceleration. However, they may only do
so if all events of default with respect to debt securities of that series have
been cured or waived. Holders of a majority in principal amount of any series
of the outstanding subordinated debt securities may, subject to some
limitations, waive any past default with respect to that series and the
consequences of the default. The prospectus supplement relating to any series
of subordinated debt securities which are original issue discount securities
will describe the particular provisions relating to acceleration of a portion
of the principal amount of those original issue discount securities upon the
occurrence and continuation of an event of default. Within 120 days after the
close of each fiscal year, we must file with the subordinated trustee a
statement, signed by specified officers of us, stating whether such officers
have knowledge of any default under the subordinated indenture.
 
   Except with respect to its duties in case of default, the subordinated
trustee is not obligated to exercise any of its rights or powers at the request
or direction of any holders of any series of outstanding subordinated debt
securities, unless those holders have offered the subordinated trustee
reasonable security or indemnity. Subject to those indemnification provisions
and limitations contained in the subordinated indenture, the holders of a
majority in principal amount of any series of the outstanding subordinated debt
securities may direct any proceeding for any remedy available to the
subordinated trustee, or the exercising of any of the subordinated trustee's
trusts or powers.
 
Modification of the indentures
 
   Senior indenture. Modifications and amendments of the senior indenture may
be made only, subject to some exceptions, with the consent of the holders of a
majority in aggregate principal amount of all outstanding debt securities under
the senior indenture which are affected by the modification or amendment.
 
                                       7
<PAGE>
 
However, the holder of each affected senior debt security must consent to any
modification or amendment of the senior indenture that:
 
  .  changes the stated maturity of the principal of, or the premium, if any,
     or any installment of interest on, that debt security;
 
  .  reduces the principal amount of, or the rate or amount of interest on,
     or any premium payable on redemption of, that debt security;
 
  .  reduces the amount of principal of an original issue discount security
     that would be due and payable upon declaration of acceleration of its
     maturity or would be provable in bankruptcy;
 
  .  adversely affects any right of repayment of the holder of that debt
     security;
 
  .  changes the place of payment where, or the currency in which, any
     payment on that debt security is payable;
 
  .  impairs the right to institute suit to enforce any payment on or with
     respect to that debt security; or
 
  .  reduces the percentage of outstanding debt securities of any series
     necessary to modify or amend the senior indenture or to waive compliance
     with some of its provisions or defaults and their consequences.
 
   We and the senior trustee may amend the senior indenture without the consent
of the holders of any senior debt securities in certain limited circumstances,
such as:
 
  .  to evidence the succession of another entity to us and the assumption by
     the successor of our covenants contained in the senior indenture;
 
  .  to secure the securities; and
 
  .  to cure any ambiguity, to correct or supplement any provision in the
     senior indenture which may be inconsistent with any other provision of
     the senior indenture.
 
   Subordinated indenture. Modifications and amendments to the subordinated
indenture may be made only, subject to some exceptions, with the consent of the
holders of a majority in aggregate principal amount of all outstanding debt
securities under the subordinated indenture which are affected by the
modification or amendment. However, the holder of each affected subordinated
debt security must consent to any modification or amendment of the subordinated
indenture that:
 
  .  changes the stated maturity of the principal of, or the premium, if any,
     or any installment of interest on, that debt security;
 
  .  reduces the principal amount of, or the rate or amount of interest on,
     or any premium payable on redemption of, that debt security;
 
  .  reduces the amount of principal of an original issue discount security
     that would be due and payable upon declaration of acceleration of its
     maturity or would be provable in bankruptcy;
 
  .  adversely affects any right of the repayment of the holder of that debt
     security;
 
  .  changes the place of payment where, or the currency in which, any
     payment on that debt security is payable;
 
  .  impairs the right to institute suit to enforce any payment on or with
     respect to that debt security;
 
  .  reduces the percentage of outstanding debt securities of any series
     necessary to modify or amend the subordinated indenture or to waive
     compliance with some of its provisions or defaults and their
     consequences; or
 
  .  subordinates the indebtedness evidenced by that debt security to any of
     our indebtedness other than senior indebtedness.
 
 
                                       8
<PAGE>
 
   We and the subordinated trustee also may amend the subordinated indenture
without the consent of the holders of any subordinated securities in certain
limited circumstances, such as:
 
  .  to evidence the succession of another entity to us and the assumption by
     the successor of our covenants contained in the subordinated indenture;
 
  .  to secure the securities; and
 
  .  to cure any ambiguity, to correct or supplement any provision in the
     subordinated indenture which may be inconsistent with any other
     provision of the subordinated indenture.
 
Defeasance and covenant defeasance
 
   When we establish a series of debt securities, we may provide that that
series is subject to the defeasance and discharge provisions of the applicable
indenture. If those provisions are made applicable, we may elect either:
 
  .  to defease and be discharged from, subject to some limitations, all of
     our obligations with respect to those debt securities; or
 
  .  to be released from our obligations to comply with specified covenants
     relating to those debt securities as described in the applicable
     prospectus supplement.
 
   To effect that defeasance or covenant defeasance, we must irrevocably
deposit in trust with the relevant trustee an amount in any combination of
funds or government obligations, which, through the payment of principal and
interest in accordance with their terms, will provide money sufficient to make
payments on those debt securities and any mandatory sinking fund or analogous
payments on those debt securities.
 
   On such a defeasance, we will not be released from obligations:
 
  .  to pay additional amounts, if any, upon the occurrence of some events;
 
  .  to register the transfer or exchange of those debt securities;
 
  .  to replace some of those debt securities;
 
  .  to maintain an office relating to those debt securities;
 
  .  to hold moneys for payment in trust will not be discharged.
 
   To establish such a trust we must, among other things, deliver to the
relevant trustee an opinion of counsel to the effect that the holders of those
debt securities:
 
  .  will not recognize income, gain or loss for U.S. federal income tax
     purposes as a result of the defeasance or covenant defeasance; and
 
  .  will be subject to U.S. federal income tax on the same amounts, in the
     same manner and at the same times as would have been the case if the
     defeasance or covenant defeasance had not occurred. In the case of
     defeasance, the opinion of counsel must be based upon a ruling of the
     IRS or a change in applicable U.S. federal income tax law occurring
     after the date of the applicable indenture.
 
   Government obligations mean generally securities which are:
 
  .  direct obligations of the U.S. or of the government which issued the
     foreign currency in which the debt securities of a particular series are
     payable, in each case, where the issuer has pledged its full faith and
     credit to pay the obligations; or
 
  .  obligations of an agency or instrumentality of the U.S. or of the
     government which issued the foreign currency in which the debt
     securities of that series are payable, the payment of which is
     unconditionally guaranteed as a full faith and credit obligation by the
     U.S. or that other government.
 
 
                                       9
<PAGE>
 
     In any case, the issuer of government obligations cannot have the option
     to call or redeem the obligations. In addition, government obligations
     include, subject to certain qualifications, a depository receipt issued
     by a bank or trust company as custodian with respect to any government
     obligation or a specific payment of interest on or principal of any such
     government obligation held by the custodian for the account of a
     depository receipt holder.
 
   If we effect covenant defeasance with respect to any debt securities, the
amount on deposit with the relevant trustee will be sufficient to pay amounts
due on the debt securities at the time of their stated maturity. However,
those debt securities may become due and payable prior to their stated
maturity if there is an event of default with respect to a covenant from which
we have not been released. In that event, the amount on deposit may not be
sufficient to pay all amounts due on the debt securities at the time of the
acceleration.
 
   The applicable prospectus supplement may further describe the provisions,
if any, permitting defeasance or covenant defeasance, including any
modifications to the provisions described above.
 
Senior debt securities
 
   Senior debt securities are to be issued under the senior indenture. Each
series of senior debt securities will constitute senior indebtedness and will
rank equally with each other series of senior debt securities and other senior
indebtedness. All subordinated debt, including, but not limited to, all
subordinated securities, will be subordinated to the senior debt securities
and other senior indebtedness.
 
Subordination of subordinated securities
 
   Subordinated indenture. Payments on the subordinated securities will be
subordinated to our senior indebtedness, whether outstanding on the date of
the subordinated indenture or incurred after that date. At September 30, 1998,
after giving pro forma effect to our issuance on December 2, 1998 of 10 1/2%
senior discount notes due 2008, our aggregate senior indebtedness was
approximately $2,646,000,000. The applicable prospectus supplement for each
issuance of subordinated securities will specify the aggregate amount of our
outstanding indebtedness as of the most recent practicable date that would
rank senior to and equally with the offered subordinated securities.
 
   Ranking. No class of subordinated securities is subordinated to any other
class of subordinated debt securities. See "Subordination provisions" below.
 
   Subordination provisions. If any of certain specified events occur, the
holders of senior indebtedness must receive payment of the full amount due on
the senior indebtedness, or that payment must be duly provided for, before we
may make payments on the subordinated securities. These events are:
 
  .  any distribution of our assets upon our liquidation, reorganization or
     other similar transaction except for a distribution in connection with a
     merger or other transaction complying with the covenant described above
     under "Merger";
 
  .  the occurrence and continuation of a payment default on any senior
     indebtedness; or
 
  .  a declaration of the principal of any series of the subordinated
     securities, or, in the case of original issue discount securities, the
     portion of the principal amount specified under their terms, as due and
     payable, that has not been rescinded and annulled.
 
   However, if the event is the acceleration of any series of subordinated
securities, only the holders of senior indebtedness outstanding at the time of
the acceleration of those subordinated securities, or, in the case of
 
                                      10
<PAGE>
 
original issue discount securities, that portion of the principal amount
specified under their terms, must receive payment of the full amount due on
that senior indebtedness, or such payment must be duly provided for, before we
make payments on the subordinated securities.
 
   As a result of the subordination provisions, some of our general creditors,
including holders of senior indebtedness, may recover more, ratably, than the
holders of the subordinated securities in the event of insolvency.
 
Definition of senior indebtedness
 
   Senior indebtedness means the following indebtedness or obligations:
 
  .  the principal of and premium, if any, and unpaid interest on
     indebtedness for money borrowed;
 
  .  purchase money and similar obligations;
 
  .  obligations under capital leases;
 
  .  guarantees, assumptions or purchase commitments relating to, or other
     transactions as a result of which we are responsible for the payment of,
     the indebtedness of others;
 
  .  renewals, extensions and refunding of that indebtedness;
 
  .  interest or obligations in respect of the indebtedness accruing after
     the commencement of any insolvency or bankruptcy proceedings; and
 
  .  obligations associated with derivative products.
 
   However, indebtedness or obligations are not senior indebtedness if the
instrument by which we become obligated for that indebtedness or those
obligations expressly provides that that indebtedness or those obligations are
junior in right of payment to any other of our indebtedness or obligations.
 
Convertible debt securities
 
   Unless otherwise provided in the applicable prospectus supplement, the
following provisions will apply to debt securities that will be convertible
into common stock or preferred stock.
 
   Conversion. The holder of unredeemed convertible debt securities may, at any
time during the period specified in the applicable prospectus supplement,
convert those convertible debt securities into shares of common stock or
preferred stock. The conversion price or rate for each $1,000 principal amount
of convertible debt securities will be specified in the applicable prospectus
supplement. The holder of a convertible debt security may convert a portion of
the convertible debt security which is $1,000 principal amount or any multiple
of $1,000. In the case of convertible debt securities called for redemption,
conversion rights will expire at the close of business on the date fixed for
the redemption. However, in the case of repayment at the option of the
applicable holder, conversion rights will terminate upon receipt of written
notice of the holder's exercise of that option.
 
   In certain events, the conversion price or rate will be subject to
adjustment as specified in the applicable indenture. For debt securities
convertible into common stock, those events include:
 
  .  the issuance of shares of common stock as a dividend;
 
  .  subdivisions and combinations of common stock;
 
  .  the issuance to all holders of common stock of rights or warrants
     entitling such holders for a period not exceeding 45 days to subscribe
     for or purchase shares of common stock at a price per share less than
     its current per share market price; and
 
                                       11
<PAGE>
 
  .  the distribution to all holders of common stock of:
 
    (1) shares of our capital stock, other than common stock;
 
    (2) evidences of our indebtedness or assets excluding cash dividends or
        distributions paid from our retained earnings; or
 
    (3) subscription rights or warrants other than those referred to above.
 
   No adjustment of the conversion price or rate will be required in any of
these cases unless an adjustment would require a cumulative increase or
decrease of at least 1% in that price or rate. Fractional shares of common
stock will not be issued upon conversion. In place of fractional shares, we
will pay a cash adjustment. Unless otherwise specified in the applicable
prospectus supplement, convertible debt securities convertible into common
stock surrendered for conversion between any record date for an interest
payment and the related interest payment date must be accompanied by payment of
an amount equal to the interest payment on the surrendered convertible debt
security. However, that payment does not have to accompany convertible debt
securities surrendered for conversion if those convertible debt securities have
been called for redemption during that period.
 
   The adjustment provisions for debt securities convertible into shares of
preferred stock will be determined at the time of an issuance of debt
securities and will be described in the applicable prospectus supplement.
 
                         Description of Preferred Stock
 
   This section describes the general terms and provisions of our preferred
stock. The applicable prospectus supplement will describe the specific terms of
the preferred stock offered through that prospectus supplement as well as any
general terms described in this section that will not apply to those shares of
preferred stock.
 
   We have summarized certain selected terms of the preferred stock in this
section. The summary is not complete. You should read our restated certificate
of incorporation that is an exhibit to our annual report on Form 10-K and the
certificate of designation relating to the applicable series of the preferred
stock that we will file with the SEC for additional information before you buy
any preferred stock.
 
General
 
   Our restated certificate of incorporation and Delaware General Corporation
Law give our board of directors the authority, without further stockholder
action, to issue a maximum of 10,000,000 shares of preferred stock. The board
of directors has the authority to fix the following terms with respect to
shares of any series of preferred stock:
 
  .  the designation of the series;
 
  .  the number of shares to comprise the series;
 
  .  the dividend rate or rates payable with respect to the shares of the
     series;
 
  .  the redemption price or prices, if any, and the terms and conditions of
     any redemption;
 
  .  the voting rights;
 
  .  any sinking fund provisions for the redemption or purchase of the shares
     of the series;
 
  .  the terms and conditions upon which the shares are convertible or
     exchangeable, if they are convertible or exchangeable; and
 
  .  any other relative rights, preferences and limitations pertaining to the
     series.
 
                                       12
<PAGE>
 
   The preferred stock will have the rights described in this section unless
the applicable prospectus supplement provides otherwise. You should read the
prospectus supplement relating to the particular series of the preferred stock
it offers for specific terms, including:
 
  .  the designation, stated value and liquidation preference of that series
     of the preferred stock and the number of shares offered;
 
  .  the initial public offering price at which the shares will be issued;
 
  .  the dividend rate or rates or method of calculation of dividends, the
     dividend periods, the date or dates on which dividends will be payable
     and whether such dividends will be cumulative or noncumulative and, if
     cumulative, the dates from which dividends shall commence to cumulate;
 
  .  any redemption or sinking fund provisions;
 
  .  any conversion or exchange provisions;
 
  .  the procedures for any auction and remarketing, if any, of that series
     of preferred stock;
 
  .  whether interests in that series of preferred stock will be represented
     by our depositary shares; and
 
  .  any additional dividend, liquidation, redemption, sinking fund and other
     rights, preferences, privileges, limitations and restrictions of that
     series of preferred stock.
 
   When we issue shares of preferred stock against payment for the shares, they
will be fully paid and nonassessable. This means that the full purchase price
for those shares will have been paid and the holders of those shares will not
be assessed any additional monies for those shares. Holders of preferred stock
will have no preemptive rights to subscribe for any additional securities that
we may issue.
 
   Because we are a holding company, our rights and the rights of holders of
our securities, including the holders of preferred stock, to participate in the
distribution of assets of any subsidiary of ours upon its liquidation or
recapitalization will be subject to the prior claims of its creditors and
preferred stockholders. We will not be structurally subordinated to the extent
we are a creditor with recognized claims against the subsidiary or are a holder
of preferred stock of the subsidiary.
 
Dividends
 
   The holders of the preferred stock will be entitled to receive dividends, if
declared by our board of directors out of our assets that we can legally use to
pay dividends. The prospectus supplement relating to a particular series of
preferred stock will describe the dividend rates and dates on which dividends
will be payable. The rates may be fixed or variable or both. If the dividend
rate is variable, the applicable prospectus supplement will describe the
formula used for determining the dividend rate for each dividend period. We
will pay dividends to the holders of record as they appear on our stock books
on the record dates fixed by our board of directors. The applicable prospectus
supplement will specify whether dividends will be paid in the form of cash,
preferred stock or common stock.
 
   The applicable prospectus supplement will also state whether dividends on
any series of preferred stock are cumulative or noncumulative. If our board of
directors does not declare a dividend payable on a dividend payment date on any
noncumulative series of preferred stock, then the holders of that series will
not be entitled to receive a dividend for that dividend period. In those
circumstances, we will not be obligated to pay the dividend accrued for that
period, whether or not dividends on such preferred stock are declared or paid
on any future dividend payment dates.
 
   Our board of directors may not declare and pay a dividend on any of our
stock ranking, as to dividends, equal with or junior to any series of preferred
stock unless full dividends on that series have been declared and
 
                                       13
<PAGE>
 
paid, or declared and sufficient money is set aside for payment. Until either
full dividends are paid, or are declared and payment is set aside, on preferred
stock ranking equal as to dividends, then:
 
  .  we will declare any dividends pro rata among the preferred stock of each
     series and any preferred stock ranking equal to the preferred stock as
     to dividends; in other words, the dividends we declare per share on each
     series of such preferred stock will bear the same relationship to each
     other that the full accrued dividends per share on each such series of
     the preferred stock bear to each other;
 
  .  other than such pro rata dividends, we will not declare or pay any
     dividends or declare or make any distributions upon any security ranking
     junior to or equal with the preferred stock as to dividends or upon
     liquidation, except dividends or distributions paid for with securities
     ranking junior to the preferred stock as to dividends and upon
     liquidation; and
 
  .  we will not redeem, purchase or otherwise acquire or set aside money for
     a sinking fund for any securities ranking junior to or equal with the
     preferred stock as to dividends or upon liquidation except by conversion
     into or exchange for stock junior to the preferred stock as to dividends
     and upon liquidation.
 
   We will not owe any interest, or any money in lieu of interest, on any
dividend payment(s) on any series of the preferred stock which may be past due.
 
Redemption
 
   Preferred stock may be redeemable, in whole or in part, at our option, and
may be subject to mandatory redemption through a sinking fund or otherwise, as
described in the applicable prospectus supplement. Redeemed preferred stock
will become authorized but unissued shares of preferred stock that we may issue
in the future.
 
   If a series of preferred stock is subject to mandatory redemption, the
applicable prospectus supplement will specify the number of shares that we will
redeem each year and the redemption price. If preferred stock is redeemed, we
will pay all accrued and unpaid dividends on those shares to, but excluding,
the redemption date. In the case of any noncumulative series of preferred
stock, accrued and unpaid dividends will not include any accumulation of
dividends for prior dividend periods. The applicable prospectus supplement will
also specify whether we will pay the redemption price in cash or other
property. If the redemption price for preferred stock of any series is payable
only from the net proceeds of the issuance of our capital stock, the terms of
that preferred stock may provide for its automatic conversion upon the
occurrence of certain events. These events include if no capital stock has been
issued or if the net proceeds from any issuance are insufficient to pay in full
the aggregate redemption price then due.
 
   If fewer than all of the outstanding shares of any series of the preferred
stock are to be redeemed, our board of directors will determine the number of
shares to be redeemed. We may redeem the shares pro rata from the holders of
record in proportion to the number of shares held by them, with adjustments to
avoid redemption of fractional shares, or by lot in a manner determined by our
board of directors.
 
   Even though the terms of a series of preferred stock may permit redemption
of shares of preferred stock in whole or in part, if any dividends, including
accumulated dividends, on that series are past due:
 
  .  we will not redeem any preferred stock of that series unless we
     simultaneously redeem all outstanding shares of preferred stock of that
     series; and
 
  .  we will not purchase or otherwise acquire any preferred stock of that
     series.
 
   The prohibition discussed in the prior sentence will not prohibit us from
purchasing or acquiring preferred stock of that series through a purchase or
exchange offer if we make the offer on the same terms to all holders of that
series.
 
                                       14
<PAGE>
 
   Unless the applicable prospectus supplement specifies otherwise, we will
give notice of a redemption by mailing a notice to each record holder of the
shares to be redeemed, between 30 to 60 days prior to the date fixed for
redemption. We will mail the notices to the holders' addresses as they appear
on our stock records. Each notice will state:
 
  .  the redemption date;
 
  .  the number of shares and the series of the preferred stock to be
     redeemed;
 
  .  the redemption price;
 
  .  the place or places where holders can surrender the certificates for the
     preferred stock for payment of the redemption price;
 
  .  that dividends on the shares to be redeemed will cease to accrue on the
     redemption date; and
 
  .  the date when the holders' conversion rights, if any, will terminate.
 
   If we redeem fewer than all shares of any series of the preferred stock held
by any holder, we will also specify the number of shares to be redeemed from
the holder in the notice.
 
   If we have given notice of the redemption and have provided the funds for
the payment of the redemption price, then beginning on the redemption date:
 
  .  the dividends on the preferred stock called for redemption will no
     longer accrue;
 
  .  such shares will no longer be considered outstanding; and
 
  .  the holders will no longer have any rights as stockholders except to
     receive the redemption price.
 
   When the holders of these shares surrender the certificates representing
these shares, in accordance with the notice, the redemption price described
above will be paid out of the funds we provide. If fewer than all the shares
represented by any certificate are redeemed, a new certificate will be issued
representing the unredeemed shares without cost to the holder of those shares.
 
Conversion or exchange rights
 
   The prospectus supplement relating to a series of preferred stock that is
convertible or exchangeable will state the terms on which shares of that series
are convertible or exchangeable into common stock, another series of preferred
stock or debt securities.
 
Rights upon liquidation
 
   Unless the applicable prospectus supplement states otherwise, if we
liquidate, dissolve or wind up our business, the holders of shares of each
series of the preferred stock will be entitled to receive:
 
  .  liquidation distributions in the amount stated in the applicable
     prospectus supplement; and
 
  .  all accrued and unpaid dividends whether or not earned or declared.
 
   We will pay these amounts to the holders of shares of each series of the
preferred stock, and all amounts owing on any preferred stock ranking equally
with that series of preferred stock as to liquidating distributions, out of our
assets available for distribution to stockholders. These payments will be made
before any distribution is made to holders of any securities ranking junior to
the series of preferred stock upon liquidation.
 
   If we liquidate, dissolve or wind up our business and the assets available
for distribution to the holders of the preferred stock of any series and any
other shares of our stock ranking equal with that series as to liquidating
distributions are insufficient to pay all amounts to which the holders are
entitled, then we will only
 
                                       15
<PAGE>
 
make pro rata distributions to the holders of all shares ranking equal as to
liquidating distributions. This means that the distributions we pay to these
holders will bear the same relationship to each other that the full
distributable amounts for which these holders are respectively entitled upon
liquidation of our business bear to each other.
 
   After we pay the full amount of the liquidation distribution to which the
holders of a series of the preferred stock are entitled, those holders will
have no right or claim to any of our remaining assets.
 
Voting rights
 
   Except as indicated below or in the applicable prospectus supplement, or
except as expressly required by applicable law, the holders of preferred stock
will not be entitled to vote.
 
   If we fail to pay dividends on any shares of preferred stock for six
consecutive quarterly periods, the holders of those shares of preferred stock,
voting separately as a class with all other series of preferred stock upon
which the same voting rights have been conferred and are exercisable, will be
entitled to vote for the election of two additional directors to the board of
directors. This may be done at a special meeting called by the holders of
record of at least 10% of those shares of preferred stock or the next annual
meeting of stockholders and at each subsequent meeting until:
 
  .  in the case of a series of preferred stock with cumulative dividends,
     all dividends accumulated on that series of preferred stock for the past
     dividend periods and the then current dividend period have been fully
     paid or declared and a sum sufficient for the payment of these dividends
     has been set aside for payment; or
 
  .  in the case of a series of noncumulative preferred stock, four
     consecutive quarterly dividends on that series of noncumulative
     preferred stock have been fully paid or declared and a sum sufficient
     for the payment of these dividends has been set aside for payment.
 
   In this case, the entire board of directors will be increased by two
directors.
 
   So long as any shares of preferred stock remain outstanding, unless we
receive the consent of the holders of any outstanding series of preferred stock
as specified below, we will not:
 
  .  authorize, issue or increase the authorized amount of, any capital stock
     ranking prior to the outstanding series of preferred stock as to
     dividends or liquidating distributions;
 
  .  reclassify any capital stock into any shares with this kind of prior
     ranking;
 
  .  authorize or issue any obligation or security that represents the right
     to purchase any capital stock with this kind of prior ranking; or
 
  .  amend or alter the provisions of our restated certificate of
     incorporation, so as to materially and adversely affect any right,
     preference, privilege or voting power of that series of preferred stock
     or the holders of that series of preferred stock.
 
   This consent must be given by the holders of at least two-thirds of each
series of all outstanding preferred stock described in the preceding sentence,
voting separately as a class. We will not be required to obtain this consent
with respect to the actions relating to changes to our restated certificate of
incorporation, however, if we only:
 
  .  increase the amount of the authorized preferred stock or any outstanding
     series of preferred stock or any of our other capital stock; or
 
  .  create and issue another series of preferred stock or any other capital
     stock; and
 
  .  in either case, this preferred stock ranks equal with or junior to the
     outstanding preferred stock as to dividends and liquidating
     distributions.

                        Description of Depositary Shares
 
   This section describes the general terms and provisions of shares of
preferred stock represented by depositary shares. The applicable prospectus
supplement will describe the specific terms of the depositary shares offered
through that prospectus supplement and any general terms outlined in this
section that will not apply to those depositary shares.
 
   We have summarized in this section certain terms and provisions of the
deposit agreement, the depositary shares and the receipts representing
depositary shares. The summary is not complete. You should read the forms of
deposit agreement and depositary receipt that we have filed with the SEC for
additional information before you buy any depositary shares that represent
preferred stock of that series.
 
General
 
   We may issue depositary receipts evidencing the depositary shares. Each
depositary share will represent a fraction of a share of preferred stock.
Shares of preferred stock of each class or series represented by depositary
shares will be deposited under a separate deposit agreement among us, the
preferred stock depositary and the holders of the depositary receipts. Subject
to the terms of the deposit agreement, each owner of a depositary receipt will
be entitled, in proportion to the fraction of a share of preferred stock
represented by the depositary shares evidenced by that depositary receipt, to
all the rights and preferences of the preferred stock represented by those
depositary shares. Those rights include any dividend, voting, conversion,
redemption and liquidation rights. Immediately following our issuance and
delivery of the preferred stock to the preferred stock depositary, we will
cause the preferred stock depositary to issue the depositary receipts on our
behalf.
 
Dividends and other distributions
 
   The preferred stock depositary will distribute all dividends or other cash
distributions received in respect of the preferred stock to the record holders
of depositary receipts in proportion to the number of depositary receipts owned
by those holders.
 
   If there is a distribution other than in cash, the preferred stock
depositary will distribute property it receives to the entitled record holders
of depositary receipts. However, if the preferred stock depositary determines
that it is not feasible to make that distribution, the preferred stock
depositary may, with our approval, sell the property and distribute the net
proceeds from this sale to the holders of depositary shares.
 
Withdrawal of stock
 
   If a holder of depositary receipts surrenders the depositary receipts at the
corporate trust office of the preferred stock depositary, the holder will be
entitled to receive the number of shares of the preferred stock and any money
or other property represented by those depositary shares. However, the holder
will not be entitled to receive these shares and related assets if the related
depositary shares have previously been called for redemption or converted or
exchanged into other securities of our company. Holders of depositary receipts
will be entitled to receive whole or fractional shares of the preferred stock
on the basis of the proportion of preferred stock represented by each
depositary share specified in the applicable prospectus supplement. Holders of
shares of preferred stock received in exchange for depositary shares will no
longer be entitled to receive depositary shares in exchange for shares of
preferred stock. If the holder delivers depositary receipts evidencing a number
of depositary shares that is more than the number of depositary shares
representing the number of shares of preferred stock to be withdrawn, the
preferred stock depositary will issue the holder a new depositary receipt
evidencing this excess number of depositary shares at the same time.
 
Redemption of depositary shares
 
   Whenever we redeem shares of preferred stock held by the preferred stock
depositary, the preferred stock depositary will redeem as of that redemption
date the number of depositary shares representing shares of the
 
                                       17
<PAGE>
 
preferred stock so redeemed. However, we must have paid in full the redemption
price of the preferred stock to be redeemed plus any accrued and unpaid
dividends on the preferred stock to the preferred stock depositary.
 
   The redemption price per depositary share will be equal to the redemption
price and any other amounts per share payable with respect to the preferred
stock. If fewer than all the depositary shares are to be redeemed, the
depositary shares to be redeemed will be selected by the preferred stock
depositary pro rata or by lot or another equitable method. In each case, we
will determine the method for selecting the depositary shares.
 
   After the date fixed for redemption, the depositary shares called for
redemption will no longer be outstanding. When the depositary shares are no
longer outstanding, all rights of the holders of the related depositary
receipts will cease, except the right to receive money or other property that
the holders of the depositary receipts were entitled to receive upon such
redemption. These payments will be made when the holders surrender their
depositary receipts to the preferred stock depositary.
 
Voting the preferred stock
 
   Upon receipt of notice of any meeting at which the holders of the preferred
stock are entitled to vote, the preferred stock depositary will mail
information about the meeting contained in the notice to the record holders of
the depositary shares representing such preferred stock. Each record holder of
depositary shares on the record date will be entitled to instruct the preferred
stock depositary as to how the preferred stock underlying the holder's
depositary shares will be voted. The record date for the depositary shares will
be the same as the record date for the preferred stock.
 
   The preferred stock depositary will vote the amount of preferred stock
represented by the depositary shares according to these instructions. We will
agree to take all reasonable action deemed necessary by the preferred stock
depositary in order to enable the preferred stock depositary to vote the
preferred stock in that manner. The preferred stock depositary will not vote
shares of preferred stock for which it does not receive specific instructions
from the holders of depositary shares representing that preferred stock. The
preferred stock depositary will not be responsible for any failure to carry out
any voting instruction, or for the manner or effect of any vote, as long as its
action or inaction is in good faith and does not result from its negligence or
willful misconduct.
 
Exchange of preferred stock
 
   Whenever we exchange all of the shares of preferred stock held by the
preferred stock depositary for debt securities or common stock, the preferred
stock depositary will exchange as of that exchange date all depositary shares
representing all of the shares of the preferred stock exchanged for debt
securities or common stock. However, we must have issued and deposited with the
preferred stock depositary debt securities or common stock for all of the
shares of the preferred stock to be exchanged.
 
   The exchange rate per depositary share will be equal to the exchange rate
per share of preferred stock, multiplied by the fraction of a share of
preferred stock represented by one depositary share, plus all money and other
property, if any, represented by such depositary shares, including all accrued
and unpaid dividends on the shares of preferred stock.
 
Conversion of preferred stock
 
   The depositary shares, as such, are not convertible or exchangeable into
common stock or any of our other securities or property. Nevertheless, the
prospectus supplement relating to an offering of depositary shares may provide
that the holders of depositary receipts may surrender their depositary receipts
to the preferred stock depositary with written instructions to the preferred
stock depositary to instruct us to cause the conversion or exchange of the
preferred stock represented by these depositary shares. We have agreed that
upon receipt of
 
                                       18
<PAGE>
 
these instructions and any related amounts payable we will cause the requested
conversion or exchange. If the depositary shares are to be converted or
exchanged in part only, a new depositary receipt or receipts will be issued for
any depositary shares not to be converted or exchanged.
 
Amendment and termination of the deposit agreement
 
   The form of depositary receipt evidencing the depositary shares and any
provision of the deposit agreement may be amended by agreement between us and
the preferred stock depositary. However, any amendment that materially and
adversely alters the rights of the holders of depositary shares or that would
be materially and adversely inconsistent with the rights granted to the holders
of the related preferred stock requires the approval of the holders of at least
two thirds of the depositary shares then outstanding.
 
   We may terminate the deposit agreement upon not less than 60 days' notice if
holders of a majority of the depository shares then outstanding consent. If we
terminate the deposit agreement, the preferred stock depositary will deliver or
make available to each holder of depositary receipts that surrenders the
depositary receipts it holds, the number of whole or fractional shares of
preferred stock represented by the depositary shares evidenced by these
depositary receipts.
 
   In addition, the deposit agreement will automatically terminate if:
 
  .  all outstanding depositary shares are redeemed, converted or exchanged;
     or
 
  .  there is a final distribution in respect of the related preferred stock
     in connection with any liquidation of our business and the distribution
     has been distributed to the holders of the related depositary receipts.
 
Charges of preferred stock depositary
 
   We will pay all transfer and other taxes and governmental charges arising
solely from the existence of the deposit agreement. In addition, we will pay
the fees and expenses of the preferred stock depositary in connection with the
performance of its duties under the deposit agreement. Holders of depositary
receipts will pay transfer and other taxes and governmental charges and any
other charges that are stated to be their responsibility in the deposit
agreement.
 
Resignation and removal of depositary
 
   The preferred stock depositary may resign at any time by delivering notice
to us. We also may remove the preferred stock depositary at any time.
Resignations or removals will take effect upon the appointment of a successor
preferred stock depositary. This successor must be appointed within 60 days
after delivery of the notice of resignation or removal and must be a bank or
trust company having its principal office in the United States and having a
combined capital and surplus of at least $50,000,000.
 
Miscellaneous
 
   The preferred stock depositary will forward to holders of depositary
receipts any reports and communications that we send to the preferred stock
depositary with respect to the related preferred stock.
 
   Neither we nor the preferred stock depositary will be liable if it is
prevented or delayed, by law or any circumstances beyond its control in
performing its obligations under the deposit agreement. Our obligations and the
preferred stock depositary's obligations under the deposit agreement will be
limited to performance in good faith and without negligence or willful
misconduct of the duties described in the deposit agreement. Neither we nor the
preferred stock depositary will be obligated to prosecute or defend any legal
proceeding relating to any depositary receipts, depositary shares or shares of
preferred stock unless satisfactory indemnity is furnished. We and the

                          Description of Common Stock
 
   We may issue, either separately or together with other securities, shares
of our common stock. Under our restated certificate of incorporation, we are
authorized to issue up to 500,000,000 shares of our common stock. A prospectus
supplement relating to an offering of common stock, or other securities
convertible or exchangeable for, or exercisable into, common stock, will
describe the relevant terms, including the number of shares offered, any
initial offering price, and market price and dividend information, as well as,
if applicable, information on other related securities. See "Description of
Outstanding Capital Stock" below.
 
                   Description of Outstanding Capital Stock
 
   We have summarized some of the terms and provisions of our outstanding
capital stock in this section. The summary is not complete. We have also filed
our restated certificate of incorporation, our by-laws and the certificate of
designation relating to the Series A preferred stock as exhibits to our annual
report on Form 10-K. You should read our restated certificate of incorporation
and our by-laws and the certificate of designation relating to the Series A
preferred stock for additional information before you purchase any of our
capital stock.
 
 
   As of January 1, 1999, our authorized capital stock was 518,500,000 shares.
Those shares consisted of:
 
  .  500,000,000 shares of common stock, par value $.01 per share;
 
  .  10,000,000 shares of preferred stock, par value $.01 per share; and
 
  .  8,500,000 shares of Class R convertible common stock, par value
     $.01 per share.
 
As of January 1, 1999 there were 307,868,632 shares of common stock, no shares
of preferred stock and no shares of Class R convertible common stock
outstanding.
 
Common stock
 
   Subject to the senior rights of preferred stock which may from time to time
be outstanding, holders of common stock are entitled to receive dividends
declared by the board of directors out of funds legally available for their
payment. Upon dissolution and liquidation of our business, holders of common
stock are entitled to a ratable share of our net assets remaining after
payment to the holders of the preferred stock of the full preferential amounts
they are entitled to. All outstanding shares of common stock are fully paid
and nonassessable.
 
   The holders of 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 common stock is Norwest Bank
Minnesota, N.A.

Preferred stock
 
   The preferred stock has priority over the common stock with respect to
dividends and to other distributions, including the distribution of assets upon
liquidation. The board of directors is authorized to fix and determine the
terms, limitations and relative rights and preferences of the preferred stock,
to establish series of preferred stock and to fix and determine the variations
as among series. The board of directors without stockholder approval could
issue preferred stock with voting and conversion rights which could adversely
affect the voting power of the holders of common stock. The board of directors
has designated 500,000 shares of Series A junior participating preferred stock.
Series A junior participating preferred stock will be issued in units
consisting of one one-thousandth of a share of Series A junior participating
preferred stock. Series A junior participating preferred stock is on a parity
with the common stock with respect to dividends and to other distributions,
including the distribution of assets on liquidation. Quarterly dividends per
unit equal the amount of the quarterly dividend paid per share of common stock,
when, as and if declared by the board of directors. The holders of units are
entitled to one vote per unit, voting together with the common stock on all
matters submitted to the stockholders. As of the date of this prospectus, there
are no outstanding shares of preferred stock.
 
Anti-takeover provisions
 
   We currently have provisions in our restated certificate of incorporation
and by-laws that could have an anti-takeover effect. The provisions in the
restated certificate of incorporation include:
 
  .  a classified board of directors;
 
  .  a prohibition on our stockholders taking action by written consent;
 
  .  the requirement that special meetings of stockholders be called only by
     the board of directors or the chairman of the board; and
 
  .  the requirement of the affirmative vote of at least 66-2/3% of our
     outstanding shares of stock entitled to vote thereon to adopt, repeal,
     alter, amend or rescind our by-laws.
 
   The by-laws contain specific procedural requirements for the nomination of
directors and the introduction of business by a stockholder of record at an
annual meeting of stockholders where such business is not specified in the
notice of meeting or brought by or at the discretion of the board of directors.
In addition to these provisions, the board of directors has adopted a
stockholder's rights plan, under which rights were distributed in a dividend.
These rights entitle the holder to acquire units of Series A junior
participating preferred stock, which is exercisable upon the occurrence of
certain events, including the acquisition by a person or group of a specified
percentage of the common stock.
 
                              Plan of Distribution
 
   We may sell the offered securities as follows:
 
   .  through agents;
 
   .  through underwriters;
 
   .  to dealers; or
 
   .  directly to one or more purchasers.
 
By agents
 
   Offered securities may be sold through agents designated by us. Unless
otherwise indicated in a prospectus supplement, the agents will use their best
efforts to solicit purchases for the period of their appointment.
 
                                       21
<PAGE>
 
By underwriters
 
   If underwriters are used in the sale, the offered securities will be
acquired by the underwriters for their own account. The underwriters may
resell the securities in one or more transactions, including negotiated
transactions, at a fixed public offering price or at varying prices determined
at the time of sale. The obligations of the underwriters to purchase the
securities will be subject to certain conditions. The underwriters will be
obligated to purchase all the securities of the series offered if any of the
securities are purchased. Any initial public offering price and any discounts
or concessions allowed or re-allowed or paid to dealers may be changed from
time to time.
 
To dealers
 
   If a dealer is used in the sale, we will sell the offered securities to the
dealer, as principal. The dealer may then resell those securities to the
public at varying prices to be determined by the dealer at the time of resale.
 
Direct sales
 
   We may also sell offered securities directly to institutional investors or
others. In this case, no underwriters or agents would be involved.
 
Delayed delivery contracts
 
   We may authorize underwriters, dealers and agents to solicit offers by
certain institutional investors to purchase offered securities under contracts
providing for payment and delivery on a future date specified in the
prospectus supplement. The prospectus supplement will also describe the public
offering price for the securities and the commission payable for solicitation
of these delayed delivery contracts. Delayed delivery contracts will contain
definite fixed price and quantity terms. The obligations of a purchaser under
these delayed delivery contracts will be subject to only two conditions:
 
  .  that the institution's purchase of the securities at the time of
     delivery of the securities is not prohibited under the law of any
     jurisdiction to which the institution is subject; and
 
  .  that we shall have sold to the underwriters the total principal amount
     of the offered securities, less the principal amount covered by the
     delayed delivery contracts.
 
General information
 
   Underwriters, dealers, agents and direct purchasers that participate in the
distribution of the offered securities may be underwriters as defined in the
Securities Act and any discounts or commissions they receive from us and any
profit on the resale of the offered securities by them may be treated as
underwriting discounts and commissions under the Securities Act. Any
underwriters, dealers or agents will be identified and their compensation
described in a prospectus supplement.
 
   We may have agreements with the underwriters, dealers and agents to
indemnify them against certain civil liabilities, including liabilities under
the Securities Act, or to contribute with respect to payments which the
underwriters, dealers or agents may be required to make.
 
   Underwriters, dealers and agents may engage in transactions with, or
perform services for, us or our subsidiaries in the ordinary course of their
businesses.
 
   The place and time of delivery of the offered securities will be described
in the prospectus supplement.

the offered securities. Any underwriters will be advised about other issues
relating to any offering by their own legal counsel.
