                                 satisfy our registration obligations under the

                                 completed, holders of Old Notes that were not
                                 prohibited from participating in the Exchange
                                 Offers and did not tender their Old Notes will
                                 not have any registration rights under the
                                 registration rights agreements with respect to
                                 the non-tendered Old Notes and, therefore, the
                                 Old Notes will continue to be subject to
                                 certain transfer restrictions.
 
Tenders, Expiration Date;
Withdrawal....................   Unless extended, the Exchange Offers will
                                 expire at 5:00 p.m., New York City time, on May
                                 27, 1999. Tenders of Old Notes pursuant to the
                                 Exchange Offers may be withdrawn and retendered
                                 at any time prior to the expiration of the
                                 Exchange Offers. Any Old Notes not accepted for
                                 exchange for any reason will be returned
                                 without expense to the tendering holder after
                                 the expiration or termination of the Exchange
                                 Offers.
 
Federal Income Tax
Considerations................   The Exchange Offers will not result in any
                                 income, gain or loss to the holders or to us
                                 for federal income tax purposes. See "Certain
                                 Federal Income Tax Considerations."
 
Use of Proceeds...............   We will receive no proceeds from the exchange
                                 of the Old Notes for the New Notes pursuant to
                                 the Exchange Offers.
 
Exchange Agent................   SunTrust Bank, Central Florida, National
                                 Association, the trustee under the indentures
                                 governing the Notes, is serving as Exchange
                                 Agent in connection with the Exchange Offers.
 
      CONSEQUENCES OF EXCHANGING OLD NOTES PURSUANT TO THE EXCHANGE OFFER
 
     Generally, holders of Old Notes, other than any holder who is our
"affiliate" within the meaning of Rule 405 under the Securities Act, who
exchange their Old Notes for New Notes pursuant to the Exchange Offers may offer
their New Notes for resale, resell their New Notes, and otherwise transfer their
New Notes without compliance with the registration and prospectus delivery
provisions of the Securities Act, provided:
 
     - the New Notes are acquired in the ordinary course of the holders'
       business,
 
     - the holders have no arrangement with any person to participate in a
       distribution of the New Notes, and
 
     - neither the holder nor any other person is engaging in or intends to
       engage in a distribution of the New Notes.

<PAGE>   5
 
     Each broker-dealer that receives New Notes for its own account in exchange
for Old Notes must acknowledge that it will deliver a prospectus in connection
with any resale of its New Notes. Broker-dealers may not exchange Old Notes
which are part of an unsold original allotment in the Exchange Offers. See "Plan
of Distribution." To comply with the securities laws of certain jurisdictions,
it may be necessary to qualify for sale or register the New Notes prior to
offering or selling such New Notes. We are required, under the registration
rights agreements, to register the New Notes in any jurisdiction reasonably
requested by the holders, subject to certain limitations. When the Exchange
Offers are completed, holders that were not prohibited from participating in the
Exchange Offers and did not tender their Old Notes will not have any
registration rights under the registration rights agreements with respect to
non-tendered Old Notes and, therefore, the Old Notes will continue to be subject
to certain transfer restrictions. In general, the Old Notes may not be offered
or sold, except in private transactions, unless registered under the Securities
Act and applicable state securities laws. See "The Exchange
Offers -- Consequences of Failure to Exchange."

 (1) Represents a one time charge to earnings as a result of the write-off of
     in-process research and development in connection with the acquisitions of
     DIGEX, Incorporated in 1997 and Shared Technologies Fairchild, Inc. in the
     first half of 1998.

 (2) EBITDA before certain charges consists of earnings (loss) before interest
     expense, interest and other income, income tax (provision) benefit,
     depreciation, amortization and charges for in-process research and
     development and business restructuring, integration and other charges
     associated with our restructuring program. EBITDA before certain charges
     does not represent funds available for management's discretionary use and
     is not intended to represent cash flow from operations. EBITDA before
     certain charges should not be considered as an alternative to net loss as
     an indicator of the Company's operating performance or to cash flows as a
     measure of liquidity. In addition, EBITDA before certain charges is not a
     term defined by generally acceptable accounting principles and as a result
     the measure of EBITDA before certain charges presented herein may not be
     comparable to similarly titled measures used by other companies. The
     Company believes that EBITDA before certain charges is often reported and
     widely used by analysts, investors and other interested parties in the
     telecommunications industry. Accordingly, this information has been
     disclosed herein to permit a more complete comparative analysis of the
     Company's operating performance relative to other companies in the
     industry.
 (3) For purposes of calculating the insufficiency of earnings to cover combined
     fixed charges: (i) earnings consist of loss before income taxes plus fixed
     charges excluding capitalized interest and preferred stock dividends and
     (ii) fixed charges consist of interest expensed and capitalized, plus
     amortization of deferred financing costs, preferred stock dividends and a
     portion of rent expense under operating leases deemed by the Company to
     represent an interest factor.
 (4) Represents long distance billable minutes for most recent fiscal quarter in
     period indicated (in millions).
 (5) Each node represents an individual point of origination and termination of
     data served by the Company's enhanced data network. In the opinion of
     management of the Company, the number of nodes reported is an accurate
     representation of the quantity of enhanced data network services provided.
 (6) Beginning in January 1997, the Company changed its definition of "Buildings
     connected" to include buildings connected to the Company's network via
     facilities leased by the Company in addition to those connected to the
     Company's network via facilities constructed by the Company. The Company
     believes the new definition is consistent with industry practice.
 (7) Cash and cash equivalents excludes investments of $7.9 million at December
     31, 1998, restricted under the terms of various notes and other agreements.
 (8) Working capital includes the restricted investments referred to in Note 7
     above whose restrictions either lapse within one year or will be used to
     pay current liabilities.
 (9) As adjusted gives effect to the issuance of the 9 1/2% Senior Notes and the
     12 1/4% Senior Subordinated Notes on February 24, 1999, as if it occurred
     on December 31, 1998.

                                  RISK FACTORS
 
     In addition to other information set forth elsewhere in this Prospectus,
before tendering your Old Notes for New Notes, you should consider carefully the
following factors which, other than "Consequences of Failure to Exchange" and
"Resale of Notes", are generally applicable to the Old Notes as well as to the
New Notes.
 
CONSEQUENCES OF FAILURE TO EXCHANGE
 
     If you do not exchange your Old Notes for New Notes pursuant to the
Exchange Offers, you will not be able to resell, offer to resell or otherwise
transfer the Old Notes unless they are registered under the Securities Act or
unless you resell them, offer to resell or otherwise transfer them under an
exemption from the registration requirements of, or in a transaction not subject
to, the Securities Act. In addition, you will no longer be able to obligate us
to register the Old Notes under the Securities Act except in the limited
circumstances provided under the registration rights agreements. In addition, if
you want to exchange your Old Notes in the Exchange Offers for the purpose of
participating in a distribution of the New Notes, you may be deemed to have
received restricted securities, and, if so, will be required to comply with the
registration and prospectus delivery requirements of the Securities Act in
connection with any resale transaction.
 
RESALE OF NOTES
 
     Based on certain no-action letters issued by the staff of the SEC, we
believe that the New Notes may be offered for resale, resold or otherwise
transferred by you without compliance with the registration and prospectus
delivery requirements of the Securities Act provided that:
 
        - you are acquiring the New Notes in the ordinary course of your
          business,
 
        - you are not participating, do not intend to participate, and have no
          arrangement or understanding with any person to participate, in the
          distribution of the New Notes within the meaning of the Securities
          Act, and
 
        - you are not an affiliate of the Company within the meaning of Rule 405
          of the Securities Act.
 
     If any of the foregoing are not true and you transfer any New Note without
delivering a prospectus meeting the requirements of the Securities Act or
without an exemption from registration of your New Notes under the Securities
Act, you may incur liability under the Securities Act. We do not and will not
assume or indemnify you against such liability.
 
     Each broker-dealer that receives New Notes for its own account in exchange
for Old Notes which were acquired by such broker-dealer as a result of market
making or other trading activities may be deemed to be an "underwriter" within
the meaning of the Securities Act and must acknowledge that it will deliver a
prospectus meeting the requirements of the Securities Act in connection with any
resale of such New Notes. The Letter of Transmittal states that by so
acknowledging and by delivering a prospectus, a broker-dealer will not be deemed
to admit that it is an "underwriter" within the meaning of the Securities Act.
This Prospectus, as it may be amended or supplemented from time to time, may be
used by a broker-dealer in connection with resales of New Notes received in
exchange for the Old Notes acquired by the broker-dealer as a result of
market-making activities or other trading activities. Broker-Dealers may not
exchange Old Notes which are part of an unsold original allotment in the
Exchange Offers. We have agreed that, for a period of 365 days after the
completion of the Exchange Offers, we will make this Prospectus available to any
broker-dealer for use in connection with any such resale of the New Notes. See
"Plan of Distribution." The New Notes may not be offered or sold unless they
have been registered or qualified for sale under applicable state securities
laws or an exemption from registration or qualification is available and is
complied with. The registration rights agreements require us to register or
qualify the New Notes for resale in any state reasonably requested by a holder,
subject to certain limitations.
 
                                        8
<PAGE>   11
 
SUBSTANTIAL DEBT
 
     Substantial Debt.  We have a significant amount of debt. Assuming we had
issued the Old Notes on December 31, 1998, we would have had outstanding
approximately $3.1 billion of debt and other liabilities, including trade
payables, and approximately $862.3 million of obligations with respect to four
outstanding series of preferred stock. As a result, we are required to pay cash
interest of approximately $128.6 million in 1999 on our outstanding notes. This
amount will increase in 2001, 2002 and 2004 when certain of our outstanding debt
which does not currently pay cash interest begins to pay cash interest.
 
     Insufficient Cash Flow.  We do not generate enough cash flow to cover our
operating and investing expenses. Our historical earnings have been insufficient
to cover combined fixed charges and dividends on preferred stock by $584.8
million for the year ended December 31, 1998. Combined fixed charges and
dividends include interest and dividends, whether paid or accrued. Assuming we
had acquired Shared Technologies Fairchild, Inc. ("Shared"), the affiliated
entities known as Long Distance Savers (collectively, "LDS") and the affiliated
entities known as National Tel (collectively, "National") and completed each of
our 1998 debt and equity offerings on January 1, 1998, our earnings would be
insufficient to cover combined fixed charges and dividends on preferred stock by
$602.3 million for the year ended December 31, 1998. Assuming we had issued the
Old Notes and completed the transactions referred to in the preceding sentence
on January 1, 1998, our earnings would have been insufficient to cover combined
fixed charges and dividends on preferred stock by $655.2 million for the year
ended December 31, 1998. We expect this situation will continue for the next
several years. Therefore, unless we develop additional sources of cash flow, we
may not be able to pay interest on our debt and dividends on our preferred stock
or repay our obligations at maturity. As an alternative, we may refinance all or
a portion of our outstanding debt. We cannot assure you that we will be able to
refinance our debt or develop additional sources of cash flow.
 
     Additional Debt.  While the terms of our outstanding debt, limit the
additional debt we may incur, they do not prohibit us from incurring more debt.
We may incur substantial additional debt during the next few years to finance
the construction of networks and purchase of network electronics, including
local/long distance voice and data switches, or for general corporate purposes,
including to fund working capital and operating losses. Any additional debt may
rank equal to the Senior Notes and senior to the Senior Subordinated Notes or
equal to the Senior Subordinated Notes. See "Description of the Senior Notes"
and "Description of the Senior Subordinated Notes."
 
     Effective Subordination of the Notes.  The Notes are not secured. Holders
of secured debt will have claims that are prior to your claims as a holder of
Notes to the extent of the assets securing such other debt. Under the terms of
the Notes, as well as the terms of our outstanding debt, we are permitted to
incur certain secured debt. We may in the future incur secured bank debt.
 
     Our subsidiaries have not guaranteed the Notes. Therefore, our subsidiaries
are not directly obligated under the Notes. At December 31, 1998, our
subsidiaries had outstanding approximately $88.1 million of debt and other
liabilities and commitments, including trade payables. Earnings generated by any
of our subsidiaries, as well as the existing assets of such subsidiaries, must
be used by such subsidiaries to fulfill their debt service requirements before
we can use them to repay our outstanding debt. In the event of a bankruptcy,
liquidation or reorganization of any of our subsidiaries, holders of their debt
and their trade creditors will generally be entitled to payment of their claims
from the assets of those subsidiaries before any assets are made available for
distribution to us. Therefore, your claims as a holder of the Notes will be
effectively subordinated to the obligations of our subsidiaries.
 
     Consequences of Debt.  Our level of debt could have important consequences
to you as a holder of the Notes. For example, it could:
 
          - make it more difficult for us to satisfy our obligations under the
     Notes;
 
          - require us to dedicate a substantial portion of our future cash flow
     from operations to the payment of the principal and interest on our debt,
     and dividends on and the redemption of our preferred stock, thereby
     reducing the funds available for other business purposes;
 
          - make us more vulnerable if there is a downturn in our business;
 
                                        9
<PAGE>   12
 
          - limit our ability to obtain additional financing for working
     capital, capital expenditures, acquisitions or other purposes; and
 
          - place us at a competitive disadvantage compared to competitors who
     have less debt than we do.
 
SUBORDINATION OF THE SENIOR SUBORDINATED NOTES
 
     The Senior Subordinated Notes rank behind all of our other existing debt,
other than trade payables, and all of our future borrowings, other than trade
payables, except any future debt that expressly provides that it ranks equal
with, or is subordinated in right of payment to, the Senior Subordinated Notes.
As a result, upon any distribution to our creditors in a bankruptcy, liquidation
or reorganization or similar proceeding relating to us or our property, the
holders of our senior debt will be entitled to be paid in full in cash before
any payment may be made with respect to the Senior Subordinated Notes.
 
     In the event of a bankruptcy, liquidation or reorganization or similar
proceeding relating to us, holders of the Senior Subordinated Notes will
participate with trade creditors and all other holders of our subordinated debt
in the assets remaining after we have paid all of the senior debt. However,
because the Senior Subordinated Note Indenture requires that amounts otherwise
payable to holders of the Senior Subordinated Notes in a bankruptcy or similar
proceeding be paid to holders of senior debt instead, holders of the Senior
Subordinated Notes may receive less, ratably, than holders of trade payables in
any such proceeding. In any of these cases, we may not have sufficient funds to
pay all of our creditors and holders of Senior Subordinated Notes may receive
less, ratably, than the holders of senior debt.
 
     Assuming we had completed the issuance of the Old Notes on December 31,
1998, the Senior Subordinated Notes would have been subordinated to $2.1 billion
of senior debt, excluding capital lease obligations. In addition, we will be
permitted to incur substantial additional debt, including senior debt, in the
future under the terms of the Senior Subordinated Note Indenture. See
"-- Substantial Debt" and "Description of the Senior Subordinated
Notes -- Subordination."
 
HISTORY OF NET LOSSES; LIMITED OPERATIONS OF CERTAIN SERVICES; NEED FOR
ADDITIONAL CAPITAL
 
     History of Net Losses.  We have incurred significant operating losses
during the past several years while we have developed our business and expanded
our networks. Although our revenues have increased in each of the last three
years, we have incurred net losses attributable to common stockholders of
approximately $57.2 million for the year ended December 31, 1996, $284.9 million
for the year ended December 31, 1997, and $577.6 million for the year ended
December 31, and 1998. We expect net losses to continue for the next several
years.
 
     Limited Operations of Certain Services.  We began operations in 1986.
Substantially all of our revenues are derived from local, long distance,
enhanced data and integration services. We have recently initiated many of these
services or expanded their availability in new market areas. We also expect to
substantially increase the size of our operations in the near future. Therefore,
you have limited historical financial information upon which to base your
evaluation of our performance and our ability to compete successfully in the
telecommunications business.
 
     Need for Additional Capital.  We require significant amounts of capital to
expand our existing networks and services and to develop new networks and
services. In addition, we may need additional capital in order to repay our
outstanding debts when they become due. See "-- Substantial Debt." We expect to
fund our capital needs by using available cash, joint ventures, debt or equity
financing, credit availability and internally generated funds. We expect that
during the second half of 2000 we will need to raise additional capital to
continue expanding our business. However, our future capital needs depend upon a
number of factors, certain of which we can control, such as marketing expenses,
staffing levels and customer growth, and others which we cannot control, such as
competitive conditions, government regulation and capital costs. Moreover, our
outstanding debt and preferred stock restrict our ability to incur additional
debt or issue additional preferred stock. Depending on market conditions, we may
decide to raise additional capital earlier. However, we cannot assure you that
we will be successful in raising sufficient debt or equity on terms that we will
consider
 
                                       10
<PAGE>   13
 
acceptable. If we cannot generate sufficient funds we may be required to delay
or abandon some of our planned expansion or expenditures. This likely would
affect our growth and our ability to repay our outstanding debt as well as the
Notes at maturity.
 
RISKS ASSOCIATED WITH ACQUISITIONS AND EXPANSION
 
     Recent Acquisitions.  In 1998, we acquired Shared, LDS and National. These
acquisitions diverted our resources and management time and require further
integration with our existing networks and services. We recorded a restructuring
charge during the second quarter of 1998 of approximately $32.3 million, which
was reduced in the third and fourth quarters by $13.5 million, upon
renegotiation of a contract and other changes in estimates. We also expensed
$34.7 million of other business restructuring, integration and other charges
during 1998. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations" in our most recent Annual Report on Form 10-K. We
cannot assure you we will successfully integrate the operations of these
acquired entities into our operations; all of the anticipated benefits from the
restructuring program will be realized; or the restructuring program will not be
more expensive or take longer than anticipated. If we cannot successfully
integrate the acquisitions and realize the benefits of the restructuring
program, we may have difficulty generating sufficient funds to repay the Notes.
 
     Possible Future Acquisitions or Dispositions.  Consistent with our
strategy, we are currently evaluating and often engage in discussions regarding
various acquisition or disposition opportunities. However, we have not reached
any agreement or agreement in principle to effect any material acquisition or
disposition. We cannot assure you that we will be able to identify suitable
acquisition opportunities or finance and complete any such acquisitions on
acceptable terms. Any future acquisitions could be funded with cash on hand
and/or by issuing additional securities. It is possible that one or more of such
possible future acquisitions or dispositions, if completed, could adversely
affect our funds from operations or cash available for distribution, in the
short term, in the long term or both, or increase our debt, or could be followed
by a decline in the market value of our outstanding securities, including the
Notes.
 
     Failure to Obtain Third Party Consents in Connection with an Acquisition or
Merger.  We consummated a number of acquisitions over the past two years,
including the acquisitions of Shared, LDS and National. We may not have obtained
or, as in the case of the acquisition of Shared, may have elected not to seek,
and in connection with future acquisitions may elect not to seek, all required
consents from third parties with respect to acquired contracts. While the
failure to obtain required third party consents does not give rise to an action
to rescind the acquisition or merger, the third party could assert a breach of
the acquired contract. We believe the failure to obtain any such third party
consents should not result in any material adverse consequences. However, we
cannot assure you that no material adverse consequences will result from any
such breach of contract claims.
 
     Expansion Risk.  We have expanded rapidly and expect this rapid expansion
to continue in the near future. This growth has increased our operating
complexity, as well as the level of responsibility for both existing and new
management personnel. In order to manage our expansion effectively, we must
continue to implement and improve our operational and financial systems and
expand, train and manage our employee base.
 
     Need to Obtain Permits and Rights-of-Way to Implement Network
Expansion.  We are continuing to expand our existing networks to pursue market
opportunities. To expand our networks requires us, among other things, to
acquire rights-of-way, pole attachment agreements and any required permits and
to finance such expansion. We cannot assure you we will be able to obtain the
necessary permits, agreements or financing to expand our existing networks on a
timely basis. If we cannot expand our existing networks in accordance with our
plans, the growth of our business could be materially adversely affected.
 
     Risk of New Service Acceptance by Customers.  We have recently introduced
and will continue to introduce new services, primarily local exchange services,
which we believe are important to our long-term growth. The success of these
services will be dependent upon, among other things, the willingness of
customers to accept us as the provider of such services. The lack of such
acceptance could have a material adverse effect on the growth of our business.
 
                                       11
<PAGE>   14
 
     Potential Diminishing Rate of Growth.  During the period from 1994 through
1998, our revenues grew at a compound annual growth rate of approximately 166%
(including the effect of acquisitions). While we expect to continue to grow, as
our size increases, it is likely our rate of growth will decrease.
 
RISKS RELATED TO INTERNET SERVICES
 
     Maintenance of Peering Relationships.  The Internet is comprised of many
Internet service providers who operate their own networks and interconnect with
other Internet service providers at various peering points. Our peering
relationships with other Internet service providers permit us to exchange
traffic with other Internet service providers without having to pay settlement
charges. Although we meet the industry's current standards for peering, we
cannot guarantee that other national Internet service providers will maintain
peering relationships with us. In addition, the requirements associated with
maintaining peering relationships with the major national Internet service
providers may change. We cannot assure you that we will be able to expand or
adapt our network infrastructure to meet any new requirements on a timely basis,
at a commercially reasonable cost, or at all.
 
     Potential Liability of On-Line Service Providers.  The law in the United
States relating to the liability of on-line service providers and Internet
service providers for information carried on, disseminated through, or hosted on
their systems is currently unsettled. If liability for materials carried on or
disseminated through their systems is imposed on Internet service providers, we
would likely implement measures to reduce our exposure to such liability. Such
measures could require us to expend substantial resources or discontinue certain
product or service offerings. In addition, increased attention on liability
issues, as a result of lawsuits, legislation and legislative proposals, could
adversely affect the growth of Internet use.
 
DEPENDENCE UPON NETWORK INFRASTRUCTURE
 
     To successfully market our services to business and government users, our
network infrastructure must provide superior reliability, capacity and security.
Our networks are subject to physical damage, power loss, capacity limitations,
software defects, breaches of security (by computer virus, break-ins or
otherwise) and other factors, certain of which have caused, and will continue to
cause, interruptions in service or reduced capacity for our customers.
Interruptions in service, capacity limitations or security breaches could have a
material adverse effect on our business, financial condition, results of
operations and prospects.
 
RAPID TECHNOLOGICAL CHANGES
 
     Communications technology is changing rapidly. While we believe, for the
foreseeable future, these changes will not materially affect the continued use
of our fiber optic networks or materially hinder our ability to acquire
necessary technologies, the effect of technological changes, such as changes
relating to emerging wire-line and wireless transmission technologies, including
software protocols, on our business cannot be predicted.
 
COMPETITION
 
     In each of our markets, when selling local services, we compete with
incumbent local exchange carriers ("ILECs"), which currently dominate their
local telecommunications markets. ILECs have longstanding relationships with
their customers which may create competitive barriers. ILECs also may have the
potential to subsidize their competitive services from revenues they earn from
their monopoly services. We also face competition in most markets in which we
operate from one or more integrated communications providers or competitive
local exchange carriers ("CLECs"). Through acquisitions, AT&T and MCI WorldCom
have entered the local services market, and other long distance carriers have
announced their intent to enter the local services market. A continuing trend
toward business combinations and alliances in the telecommunications industry
may create significant new or larger competitors. The recent mergers of MCI and
WorldCom and of AT&T with Teleport Communications Group, Inc. and
Tele-Communications, Inc. as well as the proposed mergers of Bell Atlantic and
GTE, and Ameritech and SBC Communications, Inc. are examples of this trend.

     Recent legislative initiatives, including the Telecommunications Act of
1996 (the "Telecommunications Act"), have removed many of the remaining
legislative barriers to local competition. Rules adopted to carry out the
provisions of the Telecommunications Act, however, remain subject to pending
administrative and judicial proceedings. We cannot predict the impact future
regulatory developments may have on our ability to compete. However, if ILECs
are permitted to substantially lower their rates or offer significant volume or
term discount pricing, our net income and/or cash flow could be materially
adversely affected.
 
     Our enhanced data services (including Internet) compete with services
offered by ILECs, long distance carriers, very small aperture terminal
(satellite dish) providers, Internet service providers and others. In
particular, the market for Internet services is extremely competitive, and there
are limited barriers to entry. When offering long distance services, we compete
with AT&T, MCI WorldCom, Sprint and others. The Telecommunications Act permits
the regional Bell operating companies ("RBOCs") to provide long distance
services in the same areas where they now provide local service once certain
criteria are met. Once the RBOCs begin to provide such services, they will be in
a position to offer single source local and long distance service similar to
that being offered by us. Our integration services compete with those offered by
equipment manufacturers, RBOCs and other ILECs, long distance carriers and
systems integrators.
 
     We cannot predict the number of competitors that will emerge as a result of
existing or new federal and state regulatory or legislative actions, but
increased competition from existing and new entities could have a material
adverse effect on our business. Many of our existing and potential competitors
have financial, personnel and other resources significantly greater than ours
which could effect our ability to compete.
 
REGULATION
 
     We are subject to federal, state and local regulation of our
telecommunications business as more fully described below. See
"Business -- Government Regulation" in our most recent Annual Report on Form
10-K. In general, regulation of the telecommunications industry is in a state of
flux. With the passage of the Telecommunications Act, Congress sought to foster
competition in the telecommunications industry. The Telecommunications Act
attempted to create a framework for companies, such as ours, to offer local
exchange service for business and residential customers in competition with
existing local telephone companies. The Telecommunications Act also sought to
open up the long distance market to additional competition by permitting RBOCs
to engage in the long distance business, under certain conditions, in the same
regions where they now offer local service. These and many other regulations are
the subject of ongoing administrative proceedings at the state and federal
levels, litigation in federal and state courts, and legislation in Congress and
state legislatures. The outcome of the various proceedings, litigation and
legislation cannot be predicted and might adversely affect our business and
operations.
 
     The Telecommunications Act and the issuance by the Federal Communication
Commission ("FCC") of rules governing local competition, particularly those
requiring the interconnection of all networks and the exchange of traffic among
the ILECs and CLECs, as well as pro-competitive policies already developed by
state regulatory commissions, have caused fundamental changes in the structure
of the markets for local exchange services. On January 25, 1999, the Supreme
Court largely reversed earlier decisions of the Eighth Circuit Court of Appeals
and held that the FCC has general jurisdiction to implement the local
competition provisions of the Telecommunications Act. The Supreme Court stated
that the FCC has authority to set pricing guidelines for CLECs to use various
portions of the ILEC's network necessary for the CLECs to provide service. These
portions of the ILEC's network are called "Unbundled Network Elements" or
"UNEs." The Supreme Court also affirmed the FCC's authority to prevent ILECs
from refusing to sell to CLECs the ILECs existing combinations of network
elements. The Supreme Court approved the FCC's establishment of "pick and
choose" rules regarding interconnection agreements between ILECs and CLECs
(which would permit a CLEC to "pick and choose" among various terms of service
in different interconnection agreements between the ILEC and other CLECs). The
Supreme Court's decision reestablishes the validity of many of the FCC rules
vacated by the Eighth Circuit. Although the Supreme Court affirmed the FCC's
authority to develop pricing guidelines, the Court did not evaluate the specific
pricing methodology adopted by the FCC and has remanded the case to the Eighth
Circuit for further consideration. In its decision, the Supreme Court also
vacated the FCC's rule that identifies the unbundled network elements that ILECs
                                       13
<PAGE>   16
 
must provide to CLECs. The Supreme Court found that the FCC had not adequately
considered certain statutory criteria for requiring ILECs to make those network
elements available to CLECs. Thus, while the Supreme Court resolved many issues,
including the FCC's jurisdictional authority, other issues remain subject to
further consideration by the courts and the FCC, and we cannot predict the
ultimate disposition of these matters. The possible impact of this decision,
including the portion dealing with unbundled network elements, on existing
interconnection agreements between ILECs and CLECs or on agreements that may be
negotiated in the future also can not be determined at this time.
 
     Although the passage of the Telecommunications Act should result in
increased opportunities for companies that are competing with the ILECs, no
assurance can be given that changes in current or future regulations adopted by
the FCC or state regulators or other legislative or judicial initiatives
relating to the telecommunications industry would not have a material adverse
effect on us.
 
     We believe we are entitled to receive reciprocal compensation from ILECs
for the transport and termination of Internet traffic pursuant to various
interconnection agreements. Some ILECs have not paid and/or have disputed these
charges, arguing the Internet service provider traffic is not local traffic as
defined by the various agreements. Both state and federal regulators currently
are considering the proper treatment of calls placed to an Internet service
provider, and whether Internet service provider calling triggers an obligation
to pay reciprocal compensation. All of the 31 states addressing the question to
date have ruled that Internet traffic is subject to reciprocal compensation
under the interconnection agreements then before them. On February 25, 1999, the
FCC ruled that Internet traffic is primarily interstate, rather than local, for
jurisdictional purposes and that Section 25(b)(5) of the Telecommunications Act,
requiring reciprocal compensation for local traffic, would not apply. But the
FCC specifically disavowed any intent to overturn prior state interpretations of
interconnection agreements as requiring reciprocal compensation for Internet
traffic or to prevent states from requiring reciprocal compensation for such
traffic in the future. Indeed, in a rulemaking initiated at the time of its
decision, the FCC has tentatively concluded that inter-carrier compensation for
Internet traffic should be governed in the future by interconnection agreements
negotiated and arbitrated as provided in the Telecommunications Act. Various
parties have challenged the FCC ruling and some of the ILECs have requested
state authorities to reconsider their prior rulings requiring reciprocal
compensation for Internet traffic in light of the FCC's determination that such
traffic is jurisdictionally interstate. All three of the states addressing
compensation for Internet traffic subsequent to the FCC's February 25 ruling,
Alabama, Nevada and Florida, have required ILECs to pay reciprocal compensation
for Internet traffic. There can be no assurance, however, that these issues will
be resolved by the FCC or all of the states or that any such resolution will be
favorable to us. We account for reciprocal compensation with the ILECs,
including activity associated with Internet traffic, as local traffic pursuant
to the terms of our interconnection agreements. Accordingly, revenue is
recognized in the period that the traffic is terminated. The circumstances
surrounding the disputes, including the status of cases that have arisen by
reason of similar disputes, is considered by management periodically in
determining whether reserves against unpaid balances are warranted. As of
December 31, 1998, provisions for reserves have not been considered necessary by
management. However, we cannot assure you that management will not determine
that a reserve is necessary at some point in the future or that ultimately these
receivables will be collected. Approximately $46.0 million of our receivables,
as of December 31, 1998, are related to such reciprocal compensation. As our
Internet service provider traffic grows, these amounts are expected to increase
and will be accounted for in the manner described above, subject to any changes
in our interconnection agreements.
 
     The regulatory status of telephone service over the Internet is presently
uncertain. We are unable to predict what regulations may be adopted in the
future or to what extent existing laws and regulations may be found by state and
federal authorities to be applicable to such services or the impact such new or
existing laws and regulations may have on our business. Specific statutes and
regulations addressing this service have not been adopted at this time and the
extent to which current laws and regulations at the state and federal levels
will be interpreted to include such Internet telephone services has not been
determined. The FCC has indicated, for example, that voice telecommunications
carried over the Internet between two telephone sets using the public switched
network may be subject to payment of access charges and Universal Service
funding obligations, while voice telecommunications using computers rather than
telephone sets may not be subject to
 
                                       14
<PAGE>   17
 
such obligations. There can be no assurance that new laws or regulations
relating to these services or a determination that existing laws are applicable
to them will not have a material adverse effect on our business.
 
REGULATORY APPROVAL OF THE OFFERING
 
     Certain of the states where we are authorized to provide local services
require us to obtain approval prior to issuing securities. Because of time
constraints, we may not have obtained all these approvals prior to consummating
the Exchange Offers. These requirements may have been pre-empted by the National
Securities Market Improvement Act of 1996, although there is no case law on this
point. We will seek the necessary approvals prior to or promptly following the
closing of the Exchange Offers. After consulting with counsel, we believe the
approvals will be granted and that seeking such approvals after the closing of
the Exchange Offers should not result in any material adverse consequences.
However, we cannot assure you that no adverse consequences will result.
 
RISK OF TERMINATION, CANCELLATION OR NON-RENEWAL OF INTEREXCHANGE AGREEMENTS,
NETWORK AGREEMENTS, LICENSES AND PERMITS
 
     We lease and/or purchase agreements for rights-of-way, utility pole
attachments, conduits and dark fiber for our fiber optic networks. Although we
do not believe any of these agreements will be canceled in the near future,
cancellation or non-renewal of certain of such agreements could materially
adversely affect our business in the affected metropolitan area. In addition, we
have certain licenses and permits from local government authorities. The
Telecommunications Act requires local government authorities to treat
telecommunications carriers and most utilities, including most ILECs and
electric companies, in a competitively neutral, non-discriminatory manner to
afford alternative carriers access to their poles, conduits and rights-of-way at
reasonable rates on non-discriminatory terms and conditions. We cannot assure
you we will be able to maintain our existing franchises, permits and rights or
to obtain and maintain the other franchises, permits and rights needed to
implement our strategy on acceptable terms. In March 1998, we acquired a 20 year
indefeasible right of use from Williams Telecommunications Group ("Williams")
that provides us with high capacity transport for our integrated voice and data
services, connecting major markets throughout the continental United States. The
indefeasible right of use may be terminated by Williams if we fail to make the
required payments and, in the event of a bankruptcy of Williams, the
indefeasible right of use may be rejected by Williams in a bankruptcy
proceeding.
 
DEPENDENCE ON KEY PERSONNEL
 
     Our continued success depends on the continued employment of certain
members of our senior management team and on our continued ability to attract
and retain highly skilled and qualified personnel. We do not have long-term
employment agreements with any of our key employees. The loss of the services of
key personnel or the inability to attract additional qualified personnel could
have a material adverse impact on our business, financial condition, results of
operations and prospects.
 
BUSINESS COMBINATIONS
 
     We have from time to time held, and continue to hold, preliminary
discussions with (i) potential strategic investors who have expressed an
interest in making an investment in or acquiring us and (ii) potential joint
venture partners looking toward the formation of strategic alliances that would
expand the reach of our networks or services without necessarily requiring an
additional investment in us. In addition to providing additional growth capital,
we believe that an alliance with an appropriate strategic investor would provide
operating synergy to, and enhance the competitive positions of, both Intermedia
and the investor within the rapidly consolidating telecommunications industry.
We cannot assure you that agreements for any of the foregoing will be reached.
 
                                       15
<PAGE>   18
 
FINANCING CHANGE OF CONTROL OFFER
 
     Upon the occurrence of certain specific kinds of change of control events,
we will be required to offer to repurchase all of our outstanding debt,
including the Notes. However, it is possible that we will not have sufficient
funds at the time of the change of control to make the required repurchase. In
addition, certain important corporate events, such as leveraged
recapitalizations that would increase the level of our indebtedness, would not
constitute a change of control. See "-- Subordination of the Senior Subordinated
Notes," "Description of the Senior Notes -- Offer to Purchase Upon Change of
Control" and "Description of the Senior Subordinated Notes -- Offer to Purchase
Upon Change of Control."
 
NO PRIOR MARKET FOR THE NOTES
 
     The New Notes are new issues of securities. We do not intend to apply for
listing of the New Notes on any securities exchange or on Nasdaq. We have been
informed by Bear, Stearns & Co. Inc., Merrill Lynch & Co., Salomon Smith Barney
Inc., NationsBanc-Montgomery Securities LLC and Warburg Dillon Read LLC, the
initial purchasers of the Old Notes, that they intend to make a market in the
New Notes after the Exchange Offers are completed. However, the initial
purchasers may cease their market-making at any time. In addition, the liquidity
of the trading market in the New Notes, and the market price quoted for the New
Notes, may be adversely affected by changes in the overall market for high yield
securities and by changes in our financial performance or prospects or in the
prospects for companies in our industry generally. As a result, we cannot assure
you that an active trading market will develop for the New Notes.
 
ORIGINAL ISSUE DISCOUNT
 
     The 12 1/4% Senior Subordinated Notes were issued at a substantial discount
from their principal amount. Consequently, after completion of the Exchange
Offers, the 12 1/4% Series B Senior Subordinated Notes will have "original issue
discount" for United States federal income tax purposes, and holders of the
Senior Subordinated Notes will be required to include amounts in gross income in
advance of receipt of any cash payment on the Senior Subordinated Notes to which
the income is attributable.
 
     Under the Senior Subordinated Note Indenture, in the event of an
acceleration of the maturity of the Senior Subordinated Notes upon the
occurrence of an Event of Default, the holders of Senior Subordinated Notes may
be entitled to recover only the amount that may be declared due and payable
pursuant to the Senior Subordinated Note Indenture, which may be less than the
principal amount at maturity of such Senior Subordinated Notes. See "Description
of the Senior Subordinated Notes -- Events of Default."
 
     If a bankruptcy case is commenced by or against us under the United States
Bankruptcy Code after the issuance of the Senior Subordinated Notes, the claim
of a holder of Senior Subordinated Notes with respect to the principal amount of
such Senior Subordinated Notes will likely be limited to an amount equal to the
sum of (1) the issue price of the Senior Subordinated Notes as of the date of
issuance of the Senior Subordinated Notes and (2) that portion of the original
issue discount that is not deemed to constitute "unmatured interest" for
purposes of the Bankruptcy Code. Accordingly, holders of the Senior Subordinated
Notes under such circumstances may, even if sufficient funds are available,
receive a lesser amount than they would be entitled to under the express terms
of the Senior Subordinated Note Indenture. In addition, there can be no
assurance that a bankruptcy court would compute the accrual of interest under
the same rules as those used for the calculation of original issue discount
under United States federal income tax law and, accordingly, a holder might be
required to recognize gain or loss in the event of a distribution related to
such bankruptcy case.
 
YEAR 2000 DATE CONVERSION
 
     To ensure that our computer systems and applications will function properly
beyond 1999, we have implemented a Year 2000 program. However, there can be no
assurance that the Year 2000 program will be successfully completed.
 
     If we cannot operate effectively after December 31, 1999, we could, among
other things, face substantial claims by our customers or loss of revenue due to
service interruptions, the inability to fulfill contractual
 
                                       16
<PAGE>   19
 
obligations or to bill customers accurately and on a timely basis, increased
expenses associated with litigation, stabilization of operations following
critical system failures and the execution of contingency plans and the
inability by customers and others to pay, on a timely basis or at all,
obligations owed to us. Under these circumstances, the adverse effects, although
not quantifiable at this time, would be material to our business, results of
operations, financial condition and prospects. For a more complete discussion of
Intermedia's Year 2000 program and the associated risks, see "Management's
Discussion and Analysis of Financial Condition and Results of
Operations -- Impact of Year 2000" in Intermedia's most recent periodic report.
 
FORWARD-LOOKING STATEMENTS
 
     Some of the statements in this Prospectus that are not historical facts are
"forward-looking statements" (as such term is defined in the Private Securities
Litigation Reform Act of 1995). Forward-looking statements can be identified by
the use of words such as "estimates," "projects," "anticipates," "expects,"
"intends," "believes" or the negative thereof or other variations thereon or by
discussions of strategy that involve risks and uncertainties. Examples of
forward-looking statements include discussions of our plans to expand our
existing networks, introduce new products, build and acquire networks in new
areas, install switches or provide local services, the estimate of market sizes
and addressable markets for our services and products, the market opportunity
presented by larger metropolitan areas, anticipated revenues from designated
markets during 1999 and statements regarding the development of our businesses,
anticipated capital expenditures and regulatory reform.
 
     Management wishes to caution you that all forward-looking statements
contained in this Prospectus are only estimates and predictions. Actual results
could differ materially from those anticipated in this Prospectus as a result of
risks facing us or actual events differing from the assumptions underlying such
statements. Such risks and assumptions include, but are not limited to, those
discussed above.

                               THE EXCHANGE OFFER
 
PURPOSE OF THE EXCHANGE OFFER
 
     We originally issued and sold the Old Notes on February 24, 1999 in
reliance upon the exemptions from registration under Rule 144A and Section 4(2)
of the Securities Act. In connection with the sale of the Old Notes, we entered
into registration rights agreements. Pursuant to the registration rights
agreements, we agreed to register with the SEC a series of notes with
substantially identical terms as 9 1/2% Senior Notes to be offered in exchange
for the 9 1/2% Senior Notes and a series of notes with substantially identical
terms as the 12 1/4% Senior Subordinated Notes to be offered in exchange for the
12 1/4% Senior Subordinated Notes. The purpose of the Exchange Offers is to
satisfy our obligations under the registration rights agreements. Holders that
are not prohibited from participating in the Exchange Offers and do not tender
all of their Old Notes will no longer have any registration rights under the
registration rights agreements.
 
TERMS OF THE EXCHANGE
 
     We are offering to exchange, subject to the conditions set forth in this
Prospectus and in the Letter of Transmittal accompanying this Prospectus, the
same principal amount of New Notes for the Old Notes tendered for exchange. The
terms of the New Notes are substantially identical to the Old Notes in all
material respects, including interest rate and maturity, except that:
 
        - the New Notes will not be subject to the restrictions on transfer,
          other than with respect to holders who are affiliates and as otherwise
          described below, and
 
        - holders of New Notes will not be entitled to certain rights of holders
          of Old Notes under the registration rights agreements.
 
     The New Notes will evidence the same debt as the Old Notes and will be
entitled to the benefits of the respective indentures. See "Description of the
Senior Notes and "Description of the Senior Subordinated Notes." The Exchange
Offers are not conditioned upon any minimum aggregate principal amount of Old
Notes being tendered for exchange.
 
     We believe that New Notes received in exchange for Old Notes may be offered
for sale, sold and otherwise transferred by any holder, other than any holder
which is our "affiliate" within the meaning of Rule 405 under the Securities
Act, without compliance with the registration and prospectus delivery
requirements of the Securities Act, provided that:
 
        - the New Notes are acquired in the ordinary course of the holder's
          business,
 
        - the holder has no arrangement or understanding with any person to
          participate in the distribution of the New Notes, and
 
        - neither the holder nor any other person is engaging in or intends to
          engage in a distribution of the New Notes.
 
     Any holder who tenders in the Exchange Offers for the purpose of
participating in a public distribution of the New Notes must comply with the
registration and prospectus delivery requirements of the Securities Act in
connection with the distribution. Broker-dealers may not exchange Old Notes
which are part of an unsold original allotment in the Exchange Offers.
 
     Tendering holders of the Old Notes will not be required to pay brokerage
commissions or fees or, subject to the instructions in the Letter of
Transmittal, transfer taxes with respect to the Exchange Offers.
 
EXPIRATION DATE; EXTENSIONS; TERMINATION; AMENDMENT
 
     The Exchange Offers will expire at 5:00 p.m., New York City time, on May
27, 1999 unless extended by us, in our sole discretion. We may extend the
expiration time and date, or otherwise amend the terms of the Exchange Offers,
at any time and from time to time by giving oral or written notice to holders of
the Old Notes and, unless otherwise required by applicable law or regulation, by
making a release to the Dow
                                       18
<PAGE>   21
 
Jones News Service on or before 9:00 a.m. of the next business day following the
expiration date. We may terminate the Exchange Offers at any time prior to 5:00
p.m., New York City time on the date the Exchange Offers expire, by giving
notice as described in the preceding sentence. During any extensions of the
Exchange Offers, all Old Notes tendered for exchange will remain subject to the
Exchange Offers. In connection with the Exchange Offers, we will comply with all
applicable requirements of the federal securities laws, including, but not
limited to, Rule 14e-1 under the Exchange Act.
 
     We expressly reserve the right to:
 
        - terminate the Exchange Offers and not accept for exchange any Old
          Notes if any event described under "Conditions to the Exchange Offers"
          has occurred and not been waived by us and
 
        - amend the terms of the Exchange Offers in any manner which, in our
          good faith judgment, is advantageous to the holders of the Old Notes,
          whether before or after any tender of the Old Notes.
 
     Unless we terminate the Exchange Offers prior to 5:00 p.m., New York City
time, on the expiration date, we will exchange the New Notes for the Old Notes
on the first business day following the expiration date.
 
PROCEDURES FOR TENDERING OLD NOTES
 
     The Exchange Offers are subject to the terms and conditions set forth in
this Prospectus and the Letter of Transmittal.
 
     Old Notes may be tendered by properly completing and signing the Letter of
Transmittal and delivering the Letter of Transmittal to the Exchange Agent at
its address set forth in this Prospectus on or prior to the expiration date,
together with:
 
        - the certificate or certificates representing the Old Notes being
          tendered and any required signature guarantees,
 
        - a timely confirmation of a book-entry transfer (a "Book-Entry
          Confirmation") of the Old Notes, if such procedure is available, into
          the Exchange Agent's account at The Depository Trust Company (the
          "Depository") pursuant to the procedure for book-entry transfer
          described below, or
 
        - the completion of the procedures for guaranteed delivery set forth
          below. See "Guaranteed Delivery Procedures."
 
     If the New Notes are to be issued in the name of the registered holder and
the registered holder has signed the Letter of Transmittal the holder's
signature need not be guaranteed. In any other case, the tendered Old Notes must
be endorsed or accompanied by written instruments of transfer in form
satisfactory to the Exchange Agent and duly executed by the registered holder
and the signature on the endorsement or instrument of transfer must be
guaranteed by a commercial bank or trust company located or having an office or
correspondent in the United States, or by a member firm of a national securities
exchange or of the National Association of Securities Dealers, Inc. (an
"Eligible Institution"). If the New Notes and/or Old Notes not exchanged are to
be delivered to an address other than that of the registered holder appearing on
the register for the Old Notes, the signature on the Letter of Transmittal must
be guaranteed by an Eligible Institution.
 
     THE METHOD OF DELIVERY OF OLD NOTES, LETTERS OF TRANSMITTAL AND ALL OTHER
DOCUMENTS IS AT THE ELECTION AND RISK OF THE HOLDER. IF SENT BY MAIL, IT IS
RECOMMENDED THAT REGISTERED MAIL, RETURN RECEIPT REQUESTED, BE USED, PROPER
INSURANCE OBTAINED, AND THE MAILING BE MADE SUFFICIENTLY IN ADVANCE OF THE
EXPIRATION DATE TO PERMIT DELIVERY TO THE EXCHANGE AGENT ON OR BEFORE THE
EXPIRATION DATE. NO LETTERS OF TRANSMITTAL OR OLD NOTES SHOULD BE SENT TO US.
 
     A tender will be deemed to have been received as of the date when the
tendering holder's properly completed and duly signed Letter of Transmittal, the
Old Notes or a Book-Entry Confirmation and all other required documents are
received by the Exchange Agent.
 
                                       19
<PAGE>   22
 
     We will determine in our sole discretion all questions as to the validity,
form, eligibility, including time of receipt, and acceptance for exchange of any
tender of Old Notes, which determination will be final and binding. We reserve
the right to reject any or all tenders not in proper form or the acceptance for
exchange of which may, in the opinion of our counsel, be unlawful. We also
reserve the right to waive any of the conditions of the Exchange Offer or any
defect, withdrawal, rejection of tender or irregularity in the tender of any Old
Notes. Neither we, the Exchange Agent nor any other person will be under any
duty to give notification of any defects, withdrawals, rejections or
irregularities or incur any liability for failure to give any such notification.
 
TERMS AND CONDITIONS OF THE LETTER OF TRANSMITTAL
 
     The Letter of Transmittal contains, among other things, the following terms
and conditions, which are part of the Exchange Offers.
 
     The holder tendering Old Notes exchanges, assigns and transfers the Old
Notes to us and irrevocably constitutes and appoints the Exchange Agent as the
holder's agent and attorney-in-fact to cause the Old Notes to be assigned,
transferred and exchanged. All authority conferred by the holder will survive
the death or incapacity of the holder and every obligation of the holder will be
binding upon the heirs, legal representatives, successors assigns, executors and
administrators of the holder.
 
     By participating in the Exchange Offers, the holder represents and warrants
that:
 
        - it has full power and authority to tender, exchange, assign and
          transfer the Old Notes and to acquire New Notes in exchange for the
          Old Notes,
 
        - is not an "affiliate" within the meaning of Rule 405 under the
          Securities Act or that, if it is our "affiliate," it will comply with
          the registration and prospectus delivery requirements of the
          Securities Act to the extent applicable,
 
        - when the Old Notes are accepted for exchange, we will acquire good and
          unencumbered title to the Old Notes, free and clear of all liens,
          restrictions, charges and encumbrances and not subject to any adverse
          claim
 
        - it will, upon request, execute and deliver any additional documents
          deemed by us to be necessary or desirable to complete the exchange,
          assignment and transfer of tendered Old Notes,
 
        - it is acquiring the New Notes offered in the ordinary course of its
          business, and
 
        - it has no arrangement with any person to participate in the
          distribution of the New Notes.
 
WITHDRAWAL RIGHTS
 
     Old Notes tendered pursuant to the Exchange Offers may be withdrawn at any
time prior to the expiration date of the Exchange Offers.
 
     To be effective, the Exchange Agent must receive at its address set forth
in this Prospectus by mail, courier, telegraphic, telex or facsimile
transmission a written notice of withdrawal. Any notice of withdrawal must
specify the person named in the Letter of Transmittal as having tendered Old
Notes to be withdrawn, the certificate numbers of Old Notes to be withdrawn, the
principal amount of Old Notes to be withdrawn, a statement that the holder is
withdrawing its election to tender the Old Notes for exchange, and the name of
the registered holder of the Old Notes, and must be signed by the holder in the
same manner as the original signature on the Letter of Transmittal, including
any required signature guarantees, or be accompanied by evidence satisfactory to
the Exchange Agent that the person withdrawing the tender has succeeded to the
beneficial ownership of the Old Notes being withdrawn. The Exchange Agent will
return the properly withdrawn Old Notes promptly following receipt of notice of
withdrawal. If Old Notes have been tendered pursuant to a book-entry transfer,
any notice of withdrawal must specify the name and number of the account at the
Depository to be credited with the withdrawn Old Notes and otherwise comply with
the procedures of the Depository. We will determine all questions as to the
validity of notices of withdrawals, including time of
 
                                       20

receipt, and such determination will be final and binding on all parties. Any
Old Notes which have been tendered for exchange but which are not exchanged will
be returned to the holder without cost as soon as practicable after withdrawal,
rejection of tender or termination of the Exchange Offers. Properly withdrawn
Old Notes may be re-tendered at any time on or prior to the expiration of the
Exchange Offer. Any Old Notes withdrawn and not re-tendered will not be
exchanged for New Notes under the Exchange Offers.
 
ACCEPTANCE OF OLD NOTES FOR EXCHANGE; DELIVERY OF SENIOR NOTES
 
     Old Notes validly tendered and not withdrawn will be accepted for exchange,
subject to the conditions of the Exchange Offers, and issuance of the New Notes
will be issued on the first business day following the expiration of the
Exchange Offers. We will be deemed to have accepted for exchange validly
tendered Old Notes when we give oral or written notice to the Exchange Agent of
our acceptance of the Old Notes for exchange.
 
     The Exchange Agent will act as agent for the tendering holders of Old Notes
for the purpose of causing the Old Notes to be assigned, transferred and
exchanged for New Notes. Upon the terms and subject to the conditions of the
Exchange Offers, the Exchange Agent will deliver New Notes in exchange for Old
Notes promptly after our acceptance of the tendered Old Notes. Tendered Old
Notes which we do not accept for exchange will be returned without expense to
the tendering holders promptly following the expiration of the Exchange Offers
or, if we terminate the Exchange Offers prior to the expiration date, promptly
after the Exchange Offers are terminated.
 
BOOK-ENTRY TRANSFER
 
     The Exchange Agent will establish an account at the Depository for purposes
of the Exchange Offers within two business days after the date of this
Prospectus. Any financial institution that is a participant in the Depository's
systems may make book-entry delivery of Old Notes by causing the Depository to
transfer the Old Notes into the Exchange Agent's account at the Depository in
accordance with the Depository's procedure for transfer.
 
     EVEN THOUGH THE OLD NOTES ARE BEING DELIVERED BY A BOOK ENTRY TRANSFER THE
LETTER OF TRANSMITTAL WITH ANY REQUIRED SIGNATURE GUARANTEES AND ANY OTHER
REQUIRED DOCUMENTS MUST BE PHYSICALLY RECEIVED BY THE EXCHANGE AGENT ON OR PRIOR
TO THE TIME THE EXCHANGE OFFERS EXPIRE.
 
CONDITIONS TO THE EXCHANGE OFFERS
 
     Notwithstanding any other provision of the Exchange Offers, we will not be
required to issue New Notes in exchange for properly tendered Old Notes and may
terminate the Exchange Offers or, at our option, modify or otherwise amend the
Exchange Offers, if any event has occurred which, in our sole judgment and
regardless of the circumstances giving rise to any such event, including any
action by us, makes it unlawful or inadvisable to proceed with the Exchange
Offers and/or with the acceptance of Old Notes for exchange or with the
exchange.
 
     We expressly reserve the right to:
 
        - terminate the Exchange Offers and not accept for exchange any Old
          Notes upon the occurrence of any of the foregoing conditions (which
          represent all of the material conditions to the acceptance by us of
          properly tendered Old Notes),
 
        - amend the Exchange Offers at any time prior to their expiration if any
          of the conditions set forth above occur, and
 
        - regardless of whether any of such conditions has occurred, amend the
          Exchange Offers in any manner which, in our good faith judgment, is
          advantageous to holders of the Old Notes.
 
     These conditions are for our sole benefit and may be waived by us, in whole
or in part, in our sole discretion. Any determination made by us that any of
these conditions has occurred will be final and binding on all holders, absent
manifest error.
                                       21
<PAGE>   24
 
     In addition, we will not accept for exchange any Old Notes tendered, and no
New Notes will be issued in exchange for Old Notes, if any stop order has been
threatened or is in effect with respect to the Registration Statement of which
this Prospectus constitutes a part or the qualification of the Indenture under
the Trust Indenture Act of 1939.
 
EXCHANGE AGENT
 
     SunTrust Bank, Central Florida, National Association, the Trustee under the
indentures governing the Senior Note and the Senior Subordinated Notes, has been
appointed as the Exchange Agent for the Exchange Offers. All executed Letters of
Transmittal, questions and requests for assistance and requests for additional
copies of this Prospectus or of the Letter of Transmittal should be directed to
the Exchange Agent, addressed as follows:
 
              SunTrust Bank, Central Florida, National Association
                             225 East Robinson St.

                      Confirm by telephone: (407) 237-5179
 
     DELIVERY TO AN ADDRESS OTHER THAN AS SET FORTH ABOVE OR TRANSMISSION OF
INSTRUCTIONS VIA FACSIMILE OTHER THAN AS SET FORTH ABOVE DOES NOT CONSTITUTE A
VALID DELIVERY.
 
SOLICITATION OF TENDERS; EXPENSES
 
     We have not retained any dealer-manager or similar agent in connection with
the Exchange Offers and will not make any payments to brokers, dealers or others
for soliciting acceptances of the Exchange Offers.
 
     We have not authorized any dealer, salesperson or other person to give any
information or represent anything not contained in this Prospectus and the
Letter of Transmittal. You must not rely on any unauthorized information. The
information in this Prospectus is current as of the date set forth on the front
cover. The Exchange Offers are not being made, nor will tenders be accepted from
or on behalf of, holders of Old Notes in any jurisdiction where the making of
the Exchange Offers or the acceptance of tender would not be in compliance with
the laws of the jurisdiction. We may, however, at the reasonable request of any
holder, take the actions we deem necessary to make the Exchange Offers in any
jurisdiction and extend the Exchange Offers to holders of Old Notes in that
jurisdiction.
 
TRANSFER TAXES
 
     Holders who tender their Old Notes in exchange for New Notes will not be
obligated to pay any transfer taxes except that holders who instruct us to
register New Notes in the name of, or request that Old Notes not tendered or not
accepted in the Exchange Offers be returned to, a person other than the
registered tendering holder will be responsible for the payment of any
applicable transfer tax.
 
CONSEQUENCES OF FAILURE TO EXCHANGE
 
     The Old Notes were not registered under the Securities Act or under the
Securities laws of any state and may not be resold, offered for resale or
otherwise transferred unless they are subsequently registered or resold pursuant
to exemption from the registration requirements of the Securities Act and
applicable state securities laws. If you do not exchange your Old Notes for New
Notes pursuant to the Exchange Offers, you will not be able to resell, offer to
resell or otherwise transfer the Old Notes unless they are registered under the
Securities Act or unless you resell them, offer to resell or otherwise transfer
them under an exemption from the registration requirements of, or in a
transaction not subject to, the Securities Act. In addition, you will no longer
be able to obligate us to register the Old Notes under the Securities Act except
in the limited circumstances provided under the registration rights agreements.
In addition, if you want to exchange your Old Notes in the Exchange Offers for
the purpose of participating in a distribution of the New Notes, you may
 
                                       22
<PAGE>   25
 
be deemed to have received restricted securities, and, if so, will be required
to comply with the registration and prospectus delivery requirements of the
Securities Act in connection with any resale transaction. We do not intend to
register the Old Notes under the Securities Act.
 
     Based on certain no-action letters issued by the staff of the SEC, we
believe that the New Notes may be offered for resale, resold or otherwise
transferred by you without compliance with the registration and prospectus
delivery requirements of the Securities Act provided that:
 
        - you are acquiring the New Notes in the ordinary course of your
          business,
 
        - you are not participating, do not intend to participate, and have no
          arrangement or understanding with any person to participate, in the
          distribution of the New Notes within the meaning of the Securities
          Act, and
 
        - you are not an affiliate of the Company within the meaning of Rule 405
          of the Securities Act.
 
     If any of the foregoing are not true and you transfer any New Note without
delivering a prospectus meeting the requirements of the Securities Act or
without an exemption from registration of your New Notes under the Securities
Act, you may incur liability under the Securities Act. We do not and will not
assume or indemnify you against such liability.
 
     Each broker-dealer that receives New Notes for its own account in exchange
for Old Notes which were acquired by such broker-dealer as a result of market
making or other trading activities may be deemed to be an "Underwriter" within
the meaning of the Securities Act and must acknowledge that it will deliver a
prospectus meeting the requirements of the Securities Act in connection with any
resale of such New Notes. The Letter of Transmittal states that by so
acknowledging and by delivering a prospectus, a broker-dealer will not be deemed
to admit that it is an "underwriter" within the meaning of the Securities Act.
See "Plan of Distribution." In addition, to comply with the securities laws of
certain jurisdictions, if applicable, the New Notes may not be offered or sold
unless they have been registered or qualified for sale in such jurisdiction or
an exemption from registration or qualification is available and is complied
with. We have agreed to register or qualify the New Notes for resale in any
jurisdictions reasonably requested by any holder, subject to certain
limitations.
 
OTHER
 
     Participation in the Exchange Offers is voluntary and holders should
carefully consider whether to accept. Holders of the Old Notes are urged to
consult their financial and tax advisors in making their own decisions on what
action to take.
 
     When the Exchange Offers are completed, holders of Old Notes that were not
prohibited from participating in the Exchange Offers and did not tender their
Old Notes will not have any registration rights under the registration rights
agreements with respect to non-tendered Old Notes and, therefore, such Old Notes
will continue to be subject to certain transfer restrictions.
 
     We have not entered into any arrangement or understanding with any person
to distribute the New Notes to be received in the Exchange Offers and to the
best of our information and belief, each person participating in the Exchange
Offers is acquiring the New Notes in its ordinary course of business and has no
arrangement or understanding with any person to participate in the distribution
of the New Notes to be received in the Exchange Offers. In this regard, we will
make each person participating in the Exchange Offers aware, through this
Prospectus or otherwise, that if the Exchange Offers are being accepted for the
purpose of secondary resale, any holder using the Exchange Offers to participate
in a distribution of New Notes to be acquired in the registered Exchange Offers
(1) may not rely on the staff position enunciated in Morgan Stanley and Co. Inc.
(avail. June 5, 1991) and Exxon Capital Holding Corp. (avail. May 13, 1988) or
similar letters and (2) must comply with registration and prospectus delivery
requirements of the Securities Act in connection with a secondary resale
transaction.

ACCOUNTING TREATMENT
 
     The New Notes will be recorded at the same carrying value as the Old Notes,
as reflected in our accounting records on the date the Exchange Offers are
consummated. Accordingly, we will recognize no gain or loss for accounting
purposes. The expenses of the Exchange Offers will be amortized over the term of
the New Notes.

     We will receive no proceeds from the Exchange Offers.

                        DESCRIPTION OF THE SENIOR NOTES
 
     You can find the definitions of certain terms used in this description
under the subheading "Certain Definitions." In this description, the word
"Company" refers only to Intermedia Communications Inc. and not to any of its
subsidiaries and the term Senior Notes refers to the 9 1/2% Senior Notes and the
9 1/2% Series B Senior Notes and not the Senior Subordinated notes.
 
     The Company will issue the 9 1/2% Series B Senior Notes under an indenture
(the "Senior Note Indenture") between itself and SunTrust Bank, Central Florida,
National Association, as trustee (the "Trustee"). The terms of the Senior Notes
include those stated in the Senior Note Indenture and those made part of the
Senior Note Indenture by reference to the Trust Indenture Act of 1939, as
amended (the "Trust Indenture Act"). Certain rights of the holders of the Senior
Notes are also set forth in registration rights agreement between Intermedia and
the initial purchasers of the Senior Notes (the "Senior Notes Registration
Rights Agreement").
 
     The following description is a summary of the material provisions of the
Senior Note Indenture and the Senior Note Registration Rights Agreement. It does
not restate those agreements in their entirety. We urge you to read the Senior
Note Indenture and the Senior Note Registration Rights Agreement because they,
and not this description, define your rights as holders of the Senior Notes.
Copies of the Senior Note Indenture and the Senior Note Registration Rights
Agreement are available as set forth below under the subheading "Additional
Information." Certain defined terms used in this description but not defined
below under the subheading "Certain Definitions" have the meanings assigned to
them in the Senior Note Indenture.
 
BRIEF DESCRIPTION OF THE SENIOR NOTES
 
     The Senior Notes:
 
           - are general unsecured obligations of the Company;
 
           - are pari passu in right of payment with all existing and future
             senior borrowings, including the Existing Senior Notes and
             borrowings under a credit facility which may be established by the
             Company. Holders of secured Indebtedness of the Company will,
             however, have claims that are prior to the claims of the Holders of
             the Senior Notes with respect to the assets securing such other
             Indebtedness.
 
     Certain of the Company's operations are conducted through its Subsidiaries
and, therefore, the Company is dependent upon the cash flow of its Subsidiaries
to meet its obligations, including its obligations under the Senior Notes. The
9 1/2% Senior Notes are, and the 9 1/2% Series B Senior Notes will be,
effectively subordinated to all indebtedness and other liabilities and
commitments (including trade payables and lease obligations) of the Company's
Subsidiaries. Any right of the Company to receive assets of any of its
Subsidiaries upon the latter's liquidation or reorganization (and the consequent
right of the Holders of the Senior Notes to participate in those assets) will be
effectively subordinated to the claims of that Subsidiary's creditors, except to
the extent that the Company is itself recognized as a creditor of such
Subsidiary, in which case the claims of the Company would still be subordinate
to any security in the assets of such Subsidiary and any indebtedness of such
Subsidiary senior to that held by the Company. As of December 31, 1998, on a pro
forma basis after giving effect to the offering of the Senior Notes and the
Senior Subordinated Notes, the Company would have had approximately $3.1 billion
of total indebtedness outstanding, including trade payables and approximately
$88.1 million of indebtedness and other liabilities of the Company's
Subsidiaries. Senior indebtedness would have accounted for approximately $2.1
billion of such total indebtedness.
 
PRINCIPAL, MATURITY AND INTEREST
 
     The Senior Note Indenture provides for the issuance by the Company of
Senior Notes with a maximum aggregate principal amount of $300.0 million. The
Company will issue 9 1/2% Series B Senior Notes in denominations of $1,000 and
integral multiples of $1,000. The 9 1/2% Series B Senior Notes will mature on
March 1, 2009.
 
                                       26
<PAGE>   29
 
     Interest on the Senior Notes will accrue at the rate of 9 1/2% per annum
and will be payable semi-annually in cash in arrears on March 1 and September 1,
commencing on September 1, 1999. The Company will make each interest payment to
the Holders of record on the immediately preceding February 15 and August 15.
 
     Interest on the Senior Notes will accrue from February 24, 1999 or, if
interest has already been paid, from the date it was most recently paid.
Interest will be computed on the basis of a 360-day year comprised of twelve
30-day months.
 
PAYING AGENT AND REGISTRAR FOR THE SENIOR NOTES
 
     The Trustee will initially act as Paying Agent and Registrar. The Company
may change the Paying Agent or Registrar without prior notice to the Holders,
and the Company or any of its Subsidiaries may act as Paying Agent or Registrar.
 
TRANSFER AND EXCHANGE
 
     A Holder may transfer or exchange Senior Notes in accordance with the
Senior Note Indenture. The Registrar and the Trustee may require a Holder, among
other things, to furnish appropriate endorsements and transfer documents and the
Company may require a Holder to pay any taxes and fees required by law or
permitted by the Senior Note Indenture. The Company is not required to transfer
or exchange any Senior Note selected for redemption. Also, the Company is not
required to transfer or exchange any Senior Note for a period of 15 days before
a selection of Senior Notes to be redeemed.
 
     The registered Holder of a Senior Note will be treated as the owner of it
for all purposes.
 
OPTIONAL REDEMPTION
 
     Prior to March 1, 2004, the 9 1/2% Series B Senior Notes will be subject to
redemption at any time at the option of the Company, in whole or in part, upon
not less than 30 nor more than 60 days' notice, at the Make-Whole Price, plus
accrued and unpaid interest and Liquidated Damages, if any, thereon to the
applicable redemption date.
 
     On or after March 1, 2004, the 9 1/2% Series B Senior Notes will be subject
to redemption at the option of the Company, in whole or in part, upon not less
than 30 nor more than 60 days' notice, at the redemption prices (expressed as
percentages of principal amount) set forth below plus accrued and unpaid
interest and Liquidated Damages, if any, thereon to the applicable redemption
date, if redeemed during the twelve-month period beginning on March 1 of the
years indicated below:

     In the event of the sale by the Company prior to March 1, 2002 of its
Capital Stock (other than Disqualified Stock) (i) to a Strategic Investor in a
single transaction or series of related transactions for an aggregate purchase
price equal to or exceeding $50.0 million or (ii) in one or more Public
Offerings (each of clauses (i) and (ii), a "Qualified Equity Offering"), up to a
maximum of 25% of the aggregate principal amount of the Senior Notes originally
issued will, at the option of the Company, be redeemable from the net cash
proceeds of such sale or sales (but only to the extent such proceeds consist of
cash or readily marketable cash equivalents received in respect of the Capital
Stock, other than Disqualified Stock, so sold) at a redemption price equal to
109.50% of the principal amount thereof plus accrued and unpaid interest and
Liquidated Damages, if any, thereon to the redemption date, provided that:
 
          (1) at least 75% of the aggregate principal amount of the Senior Notes
     originally issued remains outstanding immediately after the occurrence of
     such redemption; and

          (2) such redemption occurs within 90 days of the date of the closing
     of each such sale.
 
MANDATORY REDEMPTION
 
     Except as set forth below under the captions "Offer to Purchase Upon Change
of Control" and "Offer to Purchase with Excess Asset Sale Proceeds," the Company
will not be required to make mandatory redemption or sinking fund payments with
respect to the Senior Notes.
 
OFFER TO PURCHASE UPON CHANGE OF CONTROL
 
     Upon the occurrence of a Change of Control, the Company will be required to
make an offer (the "Change of Control Offer") to each holder of Senior Notes to
repurchase all or any part (equal to $1,000 or an integral multiple thereof) of
such holder's Senior Notes at a purchase price equal to 101% of the aggregate
principal amount thereof plus accrued and unpaid interest and Liquidated
Damages, if any, thereon to the date of purchase (the "Change of Control
Payment"). The Change of Control Offer must be commenced within 30 days
following a Change of Control, must remain open for at least 30 and not more
than 40 days (unless required by applicable law) and must comply with the
requirements of Rule 14e-1 under the Exchange Act and any other applicable
securities laws and regulations.
 
     Except as described above with respect to a Change of Control, the Senior
Note Indenture will not contain provisions that permit the holders of the Senior
Notes to require that the Company repurchase or redeem the Senior Notes in the
event of a takeover, recapitalization or similar transaction.
 
     Due to the leveraged structure of the Company and the effective
subordination of the Senior Notes to secured Indebtedness of the Company and
Indebtedness of the Company's Subsidiaries, the Company may not have sufficient
funds available to purchase the Senior Notes tendered in response to a Change of
Control Offer. In addition, the Existing Senior Notes or other agreements
relating to Indebtedness of the Company's Subsidiaries may contain prohibitions
or restrictions on the Company's ability to effect a Change of Control Payment.
 
     The definition of Change of Control includes a phrase relating to the sale,
lease, transfer, conveyance or other disposition of "all or substantially all"
of the Company's assets. Although there is a developing body of case law
interpreting the phrase "substantially all," there is no precise established
definition of the phrase under applicable law. Accordingly, the ability of a
holder of Senior Notes to require the Company to repurchase such Senior Notes as
a result of a sale, lease, transfer, conveyance or other disposition of less
than all of the assets of the Company to another Person may be uncertain.
 
OFFER TO PURCHASE WITH EXCESS ASSET SALE PROCEEDS
 
     When the cumulative amount of Excess Proceeds (as defined below under the
subheading "Certain Covenants -- Asset Sales") exceeds $10.0 million, the
Company will make an offer to all holders of Senior Notes and Pari Passu Notes
(an "Excess Proceeds Offer"), to purchase the maximum principal amount and/or
accreted value as applicable of Senior Notes and Pari Passu Notes that may be
purchased out of such Excess Proceeds, at an offer price in cash in an amount
equal to 100% of the outstanding principal amount of the Senior Notes and 100%
of the accreted value or 100% of the outstanding principal amount, as
applicable, of the Pari Passu Notes, plus accrued and unpaid interest and
Liquidated Damages thereon, if any, to the date fixed for the closing of such
offer, in accordance with the procedures specified in the Senior Note Indenture.
 
     If the aggregate principal amount and/or accreted value, as the case may
be, of Senior Notes and Pari Passu Notes surrendered by holders thereof exceeds
the amount of Excess Proceeds, the Trustee will select the Senior Notes and Pari
Passu Notes to be purchased on a pro rata basis. To the extent that the
aggregate amount of Senior Notes and Pari Passu Notes tendered pursuant to an
Excess Proceeds Offer is less than the amount of Excess Proceeds, the Company
may use such deficiency for general purposes. Upon completion of an Excess
Proceeds Offer, the amount of Excess Proceeds will be reset at zero.

SELECTION OF SENIOR NOTES FOR REDEMPTION OR OFFERS TO PURCHASE
 
     If less than all of the Senior Notes are to be redeemed at any time, the
Trustee will select Senior Notes for redemption as follows:
 
          (1) if the Senior Notes are listed, in compliance with the
     requirements of the principal national securities exchange on which the
     Senior Notes are listed; or
 
          (2) if the Senior Notes are not so listed, on a pro rata basis, by lot
     or by such method as the Trustee shall deem fair and appropriate.
 
     No Senior Notes of $1,000 or less shall be redeemed in part. Notices of
redemption shall be mailed by first class mail at least 30 but not more than 60
days before the redemption date to each holder of Senior Notes to be redeemed at
its registered address. Notices of redemption may not be conditional.
 
     If any Senior Note is to be redeemed in part only, the notice of redemption
that relates to that Senior Note shall state the portion of the principal amount
thereof to be redeemed. A new Senior Note in principal amount equal to the
unredeemed portion of the original Senior Note will be issued in the name of the
Holder thereof upon cancellation of the original Senior Note. Senior Notes
called for redemption become due on the date fixed for redemption. On and after
the redemption date, interest ceases to accrue on the Senior Notes or portions
of them called for redemption.
 
CERTAIN COVENANTS
 
     Restricted Payments
 
     The Company and its Subsidiaries may not, directly or indirectly:
 
          (i) declare or pay any dividend or make any distribution on account of

     dividends or distributions payable (A) in Equity Interests of the Company
     that are not Disqualified Stock or (B) to the Company or any Subsidiary;
 
          (ii) purchase, redeem, defease, retire or otherwise acquire for value

          (iii) Retire for value any Indebtedness of (A) the Company that is

     accordance with the mandatory redemption or repayment provisions set forth
     in the original documentation governing such Indebtedness; or
 
          (iv) make any Restricted Investment (all such payments and other
     actions set forth in clauses (i) through (iv) above being collectively
     referred to as "Restricted Payments"), unless, at the time of such
     Restricted Payment:
 
             (a) no Default or Event of Default has occurred and is continuing
        or would occur as a consequence thereof;
 
             (b) after giving effect to such Restricted Payment on a pro forma
        basis as if such Restricted Payment had been made at the beginning of
        the applicable four-quarter period, the Company could incur at least
        $1.00 of additional Indebtedness pursuant to the Consolidated Cash Flow
        Leverage Ratio test described under the subheading "Incurrence of
        Indebtedness and Issuance of Disqualified Stock;" and
 
             (c) such Restricted Payment, together with the aggregate of all
        other Restricted Payments made by the Company and its Subsidiaries after
        the Issue Date (including any Restricted Payments made pursuant to
        clauses (i), (v) and (vi) of the next paragraph), is less than the sum
        of
 
                (w) 50% of the Consolidated Net Income of the Company for the

           of the Company's most recently ended fiscal

           quarter for which internal financial statements are available at the
           time of such Restricted Payment (or, if such Consolidated Net Income
           for such period is a deficit, less 100% of such deficit), plus
 
                (x) 100% of the aggregate net cash proceeds received by the
           Company from the issue or sale of Equity Interests of the Company or
           of debt securities or Disqualified Stock of the Company that have
           been converted into such Equity Interests (other than Equity
           Interests (or convertible debt securities) sold to a Subsidiary of
           the Company and other than Disqualified Stock or debt securities that
           have been converted into Disqualified Stock) after June 30, 1996
           (other than any such Equity Interests, the proceeds of which were
           used as set forth in clauses (ii) and (viii) below) plus
 
                (y) 100% of the sum of, without duplication, (1) aggregate
           dividends or distributions received by the Company or any Subsidiary
           from any Joint Venture (other than dividends or distributions to pay
           any obligations of such Joint Venture to Persons other than the
           Company or any Subsidiary, such as income taxes), with non-cash
           distributions to be valued at the lower of book value or fair market
           value as determined by the Board of Directors, (2) the amount of the
           principal and interest payments received since the Issue Date by the
           Company or any Subsidiary from any Joint Venture and (3) the net
           proceeds from the sale of an Investment in a Joint Venture received
           by the Company or any Subsidiary; provided that there is no
           obligation to return any such amounts to the Joint Venture, and
           excluding any such dividend, distribution, interest payment or net
           proceeds that constitutes a return of capital invested pursuant to
           clause (vi) of the next succeeding paragraph, plus
 
                (z) $10.0 million.
 
     The foregoing provisions will not prohibit:
 
          (i) the payment of any dividend within 60 days after the date of
     declaration thereof, if at such date of declaration such payment would have
     complied with the provisions of the Senior Note Indenture;
 
          (ii) the Retirement of (A) any Equity Interests of the Company or any
     Subsidiary of the Company, (B) Indebtedness of the Company that is
     subordinate to the Senior Notes or (C) Indebtedness of a Subsidiary of the
     Company, in exchange for, or out of the proceeds of the substantially
     concurrent sale (other than to a Subsidiary of the Company) of, Equity
     Interests of the Company (other than Disqualified Stock);
 
          (iii) the Retirement of any Indebtedness of the Company subordinated
     in right of payment to the Senior Notes in exchange for, or out of the
     proceeds of the substantially concurrent Incurrence of Indebtedness of the
     Company (other than Indebtedness to a Subsidiary of the Company), but only
     to the extent that such new Indebtedness is permitted under the covenant
     described below under the subheading "Incurrence of Indebtedness and
     Issuance of Disqualified Stock" and (A) is subordinated in right of payment
     to the Senior Notes at least to the same extent as, (B) has a Weighted
     Average Life to Maturity at least as long as, and (C) has no scheduled
     principal payments due in any amount earlier than, any equivalent amount of
     principal under the Indebtedness so Retired;
 
          (iv) the Retirement of any Indebtedness of a Subsidiary of the Company
     in exchange for, or out of the proceeds of the substantially concurrent
     incurrence of Indebtedness of the Company or any Subsidiary but only to the
     extent that such incurrence is permitted under the covenant described below
     under the subheading "Incurrence of Indebtedness and Issuance of
     Disqualified Stock" and only to the extent that such Indebtedness (A) is
     not secured by any assets of the Company or any Subsidiary to a greater
     extent than the Retired Indebtedness was so secured, (B) has a Weighted
     Average Life to Maturity at least as long as the Retired Indebtedness and
     (C) if such Retired Indebtedness was an obligation of the Company, is pari
     passu or subordinated in right of payment to the Senior Notes at least to
     the same extent as the Retired Indebtedness;

<PAGE>   33
 
          (v) the Retirement of any Equity Interests of the Company or any
     Subsidiary of the Company held by any member of the Company's (or any of
     its Subsidiaries') management pursuant to any management equity
     subscription agreement or stock option agreement; provided that the
     aggregate price paid for all such repurchased, redeemed, acquired or
     retired Equity Interests shall not exceed $5.0 million in any twelve-month
     period plus the aggregate cash proceeds received by the Company during such
     twelve-month period from any reissuance of Equity Interests by the Company
     to members of management of the Company and its Subsidiaries;
 
          (vi) Investments in any Joint Venture; provided that at the time any
     such Investment is made, such Investment will not cause the aggregate
     amount of Investments at any one time outstanding under this clause (vi) to
     exceed the greater of (A) $25.0 million and (B) 5% of the Total Common
     Equity of the Company;
 
          (vii) the payment of cash in lieu of fractional shares (A) payable as
     dividends on Equity Interests of the Company or (B) issuable upon
     conversion of or in exchange for securities convertible into or
     exchangeable for Equity Interests of the Company or (C) issuable as a
     result of a corporate reorganization, provided that, in the case of (A) and
     (B), the issuance of such Equity Interests or securities and, in the case
     of (C), such corporate reorganization, is permitted under the terms of the
     Senior Note Indenture; and
 
          (viii) Investments with the net cash proceeds received by the Company
     from the issue or sale of Equity Interests of the Company (other than
     Disqualified Stock) after December 31, 1997;
 
          provided, however, that at the time of, and after giving effect to,
     any Restricted Payment permitted under clauses (i), (ii), (iii), (iv), (v),
     (vi) and (viii) no Default or Event of Default shall have occurred and be
     continuing.
 
     A Permitted Investment that ceases to be a Permitted Investment pursuant to
the definition of that term, shall become a Restricted Investment, deemed to
have been made on the date that it ceases to be a Permitted Investment.
 
     The Board of Directors may designate any Subsidiary to be an Unrestricted
Subsidiary if such designation would not cause a Default or an Event of Default.
For purposes of making such determination, all outstanding Investments by the
Company and its Subsidiaries (except to the extent repaid in cash) in such
Subsidiary so designated will be deemed to be Restricted Payments at the time of
such designation and will reduce the amount available for Restricted Payments
under the first paragraph of this covenant. All such outstanding Investments
will be deemed to constitute Investments in an amount equal to the greatest of
(x) the net book value of such Investments at the time of such designation, (y)
the fair market value of such Investments at the time of such designation and
(z) the original fair market value of such Investments at the time they were
made. Such designation will only be permitted if such Restricted Payment would
be permitted at such time.
 
     The Board of Directors of the Company may at any time designate any
Unrestricted Subsidiary to be a Subsidiary; provided that such designation shall
be deemed to be an incurrence of Indebtedness by a Subsidiary of the Company of
any outstanding Indebtedness of such Unrestricted Subsidiary and such
designation shall only be permitted if (i) such Indebtedness is permitted under
the covenant described under the subheading "Incurrence of Indebtedness and
Issuance of Disqualified Stock," and (ii) no Default or Event of Default would
be in existence following such designation.
 
     Not later than the date of making any Restricted Payment, the Company shall
deliver to the Trustee an Officers' Certificate stating that such Restricted
Payment is permitted and setting forth the basis upon which the calculations
required by the covenant described under the subheading "Restricted Payments"
were computed, which calculations may be based upon the Company's latest
available financial statements.

     Incurrence of Indebtedness and Issuance of Disqualified Stock
 
     The Company and its Subsidiaries may not, directly or indirectly, create,
incur, issue, assume, guarantee or otherwise become directly or indirectly
liable for the payment of (collectively, "incur" and, correlatively, "incurred"
and "incurrence") any Indebtedness (including, without limitation, Acquired
Debt) and may not issue any Disqualified Stock, provided, however, that the
Company and/or any of its Subsidiaries may incur Indebtedness (including,
without limitation, Acquired Debt) or issue shares of Disqualified Stock if,
after giving effect to the incurrence of such Indebtedness or the issuance of
such Disqualified Stock, the Consolidated Cash Flow Leverage Ratio for the
Company's most recently ended four full fiscal quarters for which internal
financial statements are available immediately preceding the date of such
incurrence or issuance:
 
          (A) does not exceed 5.5 to 1 if such incurrence or issuance occurs on
     or prior to June 1, 1999; and
 
          (B) does not exceed 5.0 to 1 if such incurrence or issuance occurs
     after June 1, 1999, in each case, determined on a pro forma basis
     (including a pro forma application of the net proceeds therefrom), as if
     the additional Indebtedness had been incurred, or the Disqualified Stock
     had been issued, as the case may be, at the beginning of such four-quarter
     period.
 
     If the Company incurs any Indebtedness or issues or redeems any Preferred
Stock subsequent to the commencement of the period for which such ratio is being
calculated but prior to the event for which the calculation of the ratio is
made, then the ratio will be calculated giving pro forma effect to any such
incurrence of Indebtedness, or such issuance or redemption of Preferred Stock,
as if the same had occurred at the beginning of the applicable period. In making
such calculation on a pro forma basis, interest attributable to Indebtedness
bearing a floating interest rate shall be computed as if the rate in effect on
the date of computation had been the applicable rate for the entire period.
 
     The foregoing limitation will not apply to (with each exception to be given
independent effect):
 
          (a) the incurrence by the Company and/or any of its Subsidiaries of
     Indebtedness under a Credit Facility in an aggregate principal amount at
     any one time outstanding (with letters of credit being deemed to have a
     principal amount equal to the maximum potential liability of the Company
     and/or any of its Subsidiaries thereunder) not to exceed $150.0 million in
     the aggregate at any one time outstanding, less the aggregate amount of all
     Net Proceeds of Asset Sales applied to permanently reduce the commitments
     with respect to such Indebtedness pursuant to the covenant described above
     under the subheading "Asset Sales;"
 
          (b) the incurrence by the Company and/or any of its Subsidiaries of
     Vendor Indebtedness, provided that the aggregate amount of such Vendor
     Indebtedness incurred does not exceed 80% of the total cost of the
     Telecommunications Related Assets financed therewith (or 100% of the total
     cost of the Telecommunications Related Assets financed therewith if such
     Vendor Indebtedness was extended for the purchase of tangible physical
     assets and was so financed by the vendor thereof or an affiliate of such
     vendor);
 
          (c) the incurrence by the Company and/or any of its Subsidiaries of
     the Existing Indebtedness, including the Existing Senior Notes;
 
          (d) the incurrence by the Company and/or any of its Subsidiaries of
     Indebtedness in an aggregate amount not to exceed $50.0 million at any one
     time outstanding;
 
          (e) the incurrence by the Company of Indebtedness, but only to the
     extent that such Indebtedness has a final maturity no earlier than, and a
     Weighted Average Life to Maturity equal to or greater than, the final
     maturity and Weighted Average Life to Maturity, respectively, of the Senior
     Notes, in an aggregate principal amount not to exceed 2.0 times the net
     cash proceeds received by the Company after June 30, 1996 from the issuance
     and sale of Equity Interests of the Company (that are not Disqualified
     Stock) plus the fair market value of Equity Interests (other than
     Disqualified Stock) issued after June 30, 1996 in connection with any
     acquisition of any Telecommunications Business;
 
                                       32
<PAGE>   35
 
          (f) the incurrence (a "Permitted Refinancing") by the Company and/or
     any of its Subsidiaries of Indebtedness issued in exchange for, or the
     proceeds of which are used to refinance, replace, refund or defease
     ("Refinance" and correlatively, "Refinanced" and "Refinancing")
     Indebtedness, other than Indebtedness incurred pursuant to clause (a)
     above, but only to the extent that:
 
             (1) the net proceeds of such Refinancing Indebtedness do not exceed
        the principal amount of and premium, if any, and accrued interest on the
        Indebtedness so Refinanced (or if such Indebtedness was issued at an
        original issue discount, the original issue price plus amortization of
        the original issue discount at the time of the repayment of such
        Indebtedness) plus the fees, expenses and costs of such Refinancing and
        reasonable prepayment premiums, if any, in connection therewith;
 
             (2) the Refinancing Indebtedness shall have a final maturity no
        earlier than, and a Weighted Average Life to Maturity equal to or
        greater than, the final maturity and Weighted Average Life to Maturity
        of the Indebtedness being Refinanced; and
 
             (3) if the Indebtedness being Refinanced is subordinated in right
        of payment to the Senior Notes, the Refinancing Indebtedness shall be
        subordinated in right of payment to the Senior Notes on terms at least
        as favorable to the holders of Senior Notes as those contained in the
        documentation governing the Indebtedness being so Refinanced;
 
          (g) the incurrence by the Company or any of its Subsidiaries of
     intercompany Indebtedness between or among the Company and any of its
     Subsidiaries;
 
          (h) the incurrence by the Company or any of its Subsidiaries of
     Hedging Obligations that are incurred for the purpose of fixing or hedging
     interest rate or foreign currency risk with respect to any floating rate
     Indebtedness that is permitted by the terms of the Senior Note Indenture to
     be outstanding; and
 
          (i) the incurrence by the Company of Indebtedness represented by the
     Senior Notes and the Senior Subordinated Notes, in each case, issued on the
     Issue Date.
 
     For purposes of determining compliance with this covenant, in the event
that an item of Indebtedness or Disqualified Stock meets the criteria of more
than one of the categories described in clauses (a) through (i) above or is
entitled to be incurred pursuant to the first paragraph of this covenant, the
Company shall, in its sole discretion, classify such item in any manner that
complies with this covenant and such item will be treated as having been
incurred pursuant to only one of such clauses or pursuant to the first paragraph
herein. Accrual of interest or dividends, the accretion of accreted value or
liquidation preference and the payment of interest or dividends in the form of
additional Indebtedness, Common Stock or Preferred Stock will not be deemed to
be an incurrence of Indebtedness for purposes of this covenant.
 
     Asset Sales
 
     The Company and its Subsidiaries may not, whether in a single transaction
or a series of related transactions occurring within any twelve-month period:
 
          (i) sell, lease, convey, dispose or otherwise transfer any assets
     (including by way of a Sale and Leaseback Transaction) other than sales,
     leases, conveyances, dispositions or other transfers:
 
             (A) in the ordinary course of business;
 
             (B) to the Company by any Subsidiary of the Company or from the
        Company to any Subsidiary of the Company;
 
             (C) that constitute a Restricted Payment, Investment or dividend or
        distribution permitted under the covenant described above under the
        subheading "Restricted Payments;" or
 
             (D) that constitute the disposition of all or substantially all of
        the assets of the Company pursuant to the covenant described below under
        the subheading "Merger, Consolidation or Sale of Assets;" or
 
                                       33
<PAGE>   36
 
          (ii) issue or sell Equity Interests in any of its Subsidiaries other
     than an issuance or sale of Equity Interests of any such Subsidiary to the
     Company or a Subsidiary of the Company;
 
     if, in the case of either (i) or (ii) above, in a single transaction or a
series of related transactions occurring within any twelve-month period, such
assets or securities:
 
          (x) have a Fair Market Value in excess of $2.0 million; or
 
          (y) are sold or otherwise disposed of for net proceeds in excess of
     $2.0 million (each of the foregoing, an "Asset Sale"), unless:
 
             (a) no Default or Event of Default exists or would occur as a
        result thereof;
 
             (b) the Company, or such Subsidiary, as the case may be, receives
        consideration at the time of such Asset Sale at least equal to the Fair
        Market Value (evidenced by a resolution of the Board of Directors of the
        Company set forth in an Officers' Certificate delivered to the Trustee),
        of the assets or securities issued or sold or otherwise disposed of; and
 
             (c) except with respect to an Asset Sale constituting the issuance
        or sale of Equity Interests in the Web Hosting Subsidiary, at least 75%
        of the consideration therefor received by the Company or such Subsidiary
        is in the form of cash, provided, however, that:
 
                (A) the amount of:
 
                    (x) any liabilities (as shown on the Company's or such
               Subsidiary's most recent balance sheet or in the notes thereto),
               of the Company or any Subsidiary of the Company (other than
               liabilities that are by their terms subordinated to the Senior
               Notes) that are assumed by the transferee of any such assets; and
 
                    (y) any notes, obligations or other securities received by
               the Company or any such Subsidiary from such transferee that are
               immediately converted by the Company or such Subsidiary into
               cash,
 
               shall be deemed to be cash (to the extent of the cash received in
               the case of subclause (y)) for purposes of this clause (c); and
 
                (B) an amount equal to the Fair Market Value (determined as set
           forth in clause (b) above) of (1) Telecommunications Related Assets
           received by the Company or any such Subsidiary from the transferee
           that will be used by the Company or any such Subsidiary in the
           operation of a Telecommunications Business in the United States and
           (2) the Voting Stock of any Person engaged in the Telecommunications
           Business in the United States received by the Company or any such
           Subsidiary (provided that such Voting Stock is converted to cash
           within 270 days or such Person concurrently becomes or is a
           Subsidiary of the Company) will be deemed to be cash for purposes of
           this clause (c).
 
     The foregoing provisions will not apply to a sale, lease, conveyance or
other disposition of all or substantially all of the assets of the Company,
which will be governed by the provisions of the Senior Note Indenture described
below under the subheading "Merger, Consolidation or Sale of Assets."
 
     Within 360 days after the receipt of net proceeds of any Asset Sale, the
Company (or such Subsidiary, as the case may be) may apply the Net Proceeds from
such Asset Sale, at its option, to:
 
          (i) permanently reduce the amounts permitted to be borrowed by the
     Company under the terms of any of its Senior Indebtedness; or
 
          (ii) the purchase of Telecommunications Related Assets or Voting Stock
     of any Person engaged in the Telecommunications Business in the United
     States (provided that such Person concurrently becomes a Subsidiary of the
     Company); or
 
          (iii) in the case of net cash proceeds realized upon the issuance or
     sale of Equity Interests in the Web Hosting Subsidiary, fund cash operating
     losses, provide working capital and for general corporate purposes.
 
                                       34
<PAGE>   37
 
     Any Net Proceeds from any Asset Sales that are not so applied or invested
will constitute "Excess Proceeds." When the aggregate amount of Excess Proceeds
exceeds $10.0 million, the Company will be required to make an Excess Proceeds
Offer in accordance with the terms set forth under the subheading "Offer to
Purchase with Excess Asset Sale Proceeds."
 
     Liens
 
     The Company and its Subsidiaries may not, directly or indirectly, create,
incur, assume or suffer to exist any Lien on any asset now owned or hereafter
acquired, or any income or profits therefrom or assign or convey any right to
receive income therefrom, except for Permitted Liens.
 
     Dividend and Other Payment Restrictions Affecting Subsidiaries
 
     The Company and its Subsidiaries may not, directly or indirectly, create or
otherwise cause to become effective any consensual encumbrance or restriction on
the ability of any Subsidiary to:
 
          (i) pay dividends or make any other distributions to the Company or
     any of its Subsidiaries on its Capital Stock or with respect to any other
     interest or participation in, or measured by, its profits, or pay any
     Indebtedness owed to the Company or any of its Subsidiaries;
 
          (ii) make loans or advances to the Company or any of its Subsidiaries;
     or
 
          (iii) transfer any of its properties or assets to the Company or any
     of its Subsidiaries; except for such encumbrances or restrictions existing
     as of the Issue Date or under or by reason of:
 
             (a) Existing Indebtedness;
 
             (b) applicable law;
 
             (c) any instrument governing Acquired Debt as in effect at the time
        of acquisition (except to the extent such Indebtedness was incurred in
        connection with, or in contemplation of, such acquisition), which
        encumbrance or restriction is not applicable to any Person, or the
        properties or assets of any Person, other than the Person, or the
        property or assets of the Person, so acquired;
 
             (d) by reason of customary non-assignment provisions in leases
        entered into in the ordinary course of business and consistent with past
        practices;
 
             (e) Indebtedness in respect of a Permitted Refinancing, provided
        that the restrictions contained in the agreements governing such
        Refinancing Indebtedness are not materially more restrictive than those
        contained in the agreements governing the Indebtedness being refinanced;
 
             (f) with respect to clause (iii) above, purchase money obligations
        for property acquired in the ordinary course of business, Vendor
        Indebtedness incurred in connection with the purchase or lease of
        Telecommunications Related Assets or performance bonds or similar
        security for performance which liens securing such obligations do not
        cover any asset other than the asset acquired or, in the case of
        performance bonds or similar security for performance, the assets
        associated with the Company's performance;
 
             (g) Indebtedness incurred under clause (a) of the covenant
        described under the subheading "Incurrence of Indebtedness and Issuance
        of Disqualified Stock;"
 
             (h) the Senior Note Indenture and the Senior Notes or future
        Indebtedness with substantially similar restrictions, if any, to the
        Senior Notes;
 
             (i) the Senior Subordinated Note Indenture and the Senior
        Subordinated Notes or future Indebtedness with substantially similar
        restrictions, if any, to the Senior Subordinated Notes; or
 
             (j) in the case of clauses (a), (c), (e), (g), (h) and (i) above,
        any amendments, modifications, restatements, renewals, increases,
        supplements, refundings, replacements or refinancings thereof, provided
        that such amendments, modifications, restatements, renewals, increases,
        supple-
 
                                       35
<PAGE>   38
 
        ments, refundings, replacements or refinancings are not materially more
        restrictive with respect to such dividend and other payment restrictions
        than those contained in such instruments as in effect on the date of
        their incurrence or, if later, the Issue Date.
 
     Merger, Consolidation or Sale of Assets
 
     The Company may not consolidate or merge with or into (whether or not the
Company is the surviving entity), or sell, assign, transfer, lease, convey or
otherwise dispose of all or substantially all of its properties or assets in one
or more related transactions to, another corporation, Person or entity unless:
 
          (i) the Company is the surviving entity or the entity or Person formed
     by or surviving any such consolidation or merger (if other than the
     Company) or to which such sale, assignment, transfer, lease, conveyance or
     other disposition has been made is a corporation organized or existing
     under the laws of the United States, any state thereof or the District of
     Columbia;
 
          (ii) the entity or Person formed by or surviving any such
     consolidation or merger (if other than the Company) or the entity or Person
     to which such sale, assignment, transfer, lease, conveyance or other
     disposition has been made assumes all the obligations of the Company under
     the Senior Notes and the Senior Note Indenture pursuant to a supplemental
     indenture in form reasonably satisfactory to the Trustee;
 
          (iii) immediately after such transaction no Default or Event of
     Default exists;
 
          (iv) except in connection with a Merger with or into a wholly owned
     Subsidiary of the Company, the Company, or any entity or Person formed by
     or surviving any such consolidation or merger, or to which such sale,
     assignment, transfer, lease, conveyance or other disposition has been made,
     at the time of such transaction after giving pro forma effect thereto as if
     such transaction had occurred at the beginning of the applicable fiscal
     quarter (including any Indebtedness incurred or anticipated to be incurred
     in connection with or in respect of such transaction or series of
     transactions), either (A) could incur at least $1.00 of additional
     Indebtedness pursuant to the Consolidated Cash Flow Leverage Ratio test
     described under the subheading "Incurrence of Indebtedness and Issuance of
     Disqualified Stock" or (B) would have (x) Total Market Capitalization of at
     least $1.0 billion and (y) total Indebtedness (net of cash and cash
     equivalents that are not restricted cash or restricted cash equivalents as
     reflected on the Company's consolidated balance sheet as of the time of
     such event) in an amount no greater than 40% of its Total Market
     Capitalization; and
 
          (v) such transaction would not result in the loss, material impairment
     or adverse modification or amendment of any authorization or license of the
     Company or its Subsidiaries that would have a material adverse effect on
     the business or operations of the Company and its Subsidiaries taken as a
     whole.
 
     Transactions with Affiliates
 
     The Company and its Subsidiaries may not sell, lease, transfer or otherwise
dispose of any of their respective properties or assets to, or purchase any
property or assets from, or enter into any contract, agreement, understanding,
loan, advance or guarantee with, or for the benefit of, any Affiliate (each of
the foregoing, an "Affiliate Transaction"), unless:
 
          (i) such Affiliate Transaction is on terms that are no less favorable
     to the Company or the relevant Subsidiary than those that would have been
     obtained in a comparable transaction by the Company or such Subsidiary with
     an unrelated Person;
 
          (ii) such Affiliate Transaction is approved by a majority of the
     disinterested directors on the Board of Directors of the Company; and
 
          (iii) the Company delivers to the Trustee, with respect to any
     Affiliate Transaction involving aggregate payments in excess of $1.0
     million, a resolution of a committee of independent directors of the
     Company set forth in an Officers' Certificate certifying that such
     Affiliate Transaction complies with clauses (i) and (ii) above;
                                       36
<PAGE>   39
 
          provided that:
 
             (a) transactions pursuant to any employment, stock option or stock
        purchase agreement entered into by the Company or any of its
        Subsidiaries, or any grant of stock, in the ordinary course of business
        that are approved by the Board of Directors of the Company;
 
             (b) transactions between or among the Company and its Subsidiaries;
 
             (c) transactions permitted by the provisions of the Senior Note
        Indenture described above under the subheading "Restricted Payments;"
        and
 
             (d) loans and advances to employees and officers of the Company or
        any of its Subsidiaries in the ordinary course of business in an
        aggregate principal amount not to exceed $1.0 million at any one time
        outstanding, shall not be deemed Affiliate Transactions.
 
     Use of Proceeds
 
     The Company may use the gross proceeds from the sale of the Senior Notes
only for the following purposes:
 
          (i) to pay the fees and expenses of the issuance of the Senior Notes
     including any discount or commission to the initial purchasers of the
     Senior Notes; and
 
          (ii) with respect to any funds remaining after application under
     clause (i) above, to fund up to 80% of the cost of the acquisition or
     construction of Telecommunications Related Assets, or to the repayment of
     the Existing Senior Notes or to pay regularly scheduled interest on the
     Senior Notes pursuant to their terms.
 
     Pending application of the proceeds in accordance with clause (ii) above,
the Company will deposit such proceeds into a segregated account in the
Company's name. The Company will deliver to the Trustee an Officer's Certificate
with each annual compliance certificate certifying that the amounts in such
account were applied in accordance with this covenant.
 
     Business Activities
 
     The Company and its Subsidiaries may not, directly or indirectly, engage in
any business other than the Telecommunications Business.
 
     Limitations on Sale and Leaseback Transactions
 
     The Company and its Subsidiaries may not, directly or indirectly, enter
into, assume, Guarantee or otherwise become liable with respect to any Sale and
Leaseback Transaction, provided that the Company or any Subsidiary of the
Company may enter into any such transaction if:
 
          (i) the Company or such Subsidiary would be permitted under the
     covenants described above under the subheadings "Incurrence of Indebtedness
     and Issuance of Disqualified Stock" and "Liens" to incur secured
     Indebtedness in an amount equal to the Attributable Debt with respect to
     such transaction;
 
          (ii) the consideration received by the Company or such Subsidiary from
     such transaction is at least equal to the Fair Market Value of the property
     being transferred; and
 
          (iii) the Net Proceeds received by the Company or such Subsidiary from
     such transaction are applied in accordance with the covenant described
     above under the subheading "Asset Sales."
 
     Reports
 
     The Company will file with the Trustee within 15 days after it files them
with the SEC copies of the annual and quarterly reports and the information,
documents, and other reports that the Company is required to file with the SEC
pursuant to Section 13(a) or 15(d) of the Exchange Act ("SEC Reports"). In the
event the Company is not required or shall cease to be required to file SEC
Reports, pursuant to the Exchange Act,
                                       37
<PAGE>   40
 
the Company will nevertheless continue to file such reports with the SEC (unless
the SEC will not accept such a filing) and the Trustee. Whether or not required
by the Exchange Act to file SEC Reports with the SEC, so long as any Senior
Notes are outstanding, the Company will furnish copies of the SEC Reports to the
holders of Senior Notes at the time the Company is required to file the same
with the Trustee and make such information available to investors who request it
in writing. In addition, the Company has agreed that, for so long as any Senior
Notes remain outstanding, it will furnish to the holders and to securities
analysts and prospective investors, upon their request, the information required
to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.
 
     Payments for Consents
 
     Neither the Company nor any of its Affiliates shall, directly or
indirectly, pay or cause to be paid any consideration, whether by way of
interest, fee or otherwise, to any holder of any Senior Notes for or as an
inducement to any consent, waiver or amendment of any of the terms or provisions
of the Senior Note Indenture or the Senior Notes unless such consideration is
offered to be paid or agreed to be paid to all holders of the Senior Notes that
consent, waive or agree to amend in the time frame set forth in the solicitation
documents relating to such consent, waiver or agreement.
 
EVENTS OF DEFAULT AND REMEDIES
 
     Each of the following constitutes an Event of Default:
 
          (i) default for 30 days in the payment when due of interest or
     Liquidated Damages, if any, on the Senior Notes;
 
          (ii) default in payment when due of principal or premium, if any, on
     the Senior Notes at maturity, upon redemption or otherwise;
 
          (iii) failure by the Company to perform or comply with the provisions
     of the covenants described above under the subheadings "Offer to Purchase
     Upon Change of Control," "Asset Sales," "Restricted Payments," "Incurrence
     of Indebtedness and Issuance of Disqualified Stock" or "Merger,
     Consolidation or Sale of Assets;"
 
          (iv) failure by the Company for 30 days after notice from the Trustee
     or the holders of at least 25% in principal amount of the Senior Notes then
     outstanding to comply with its other agreements in the Senior Note
     Indenture or the Senior Notes;
 
          (v) default under any mortgage, indenture or instrument under which
     there may be issued or by which there may be secured or evidenced any
     Indebtedness for money borrowed by the Company or any of its Subsidiaries
     (or the payment of which is guaranteed by the Company or any of its
     Subsidiaries), whether such Indebtedness or Guarantee now exists, or is
     created after the Issue Date, which default (x) is caused by a failure to
     pay when due principal, premium, if any, or interest on such Indebtedness
     within the grace period provided in such Indebtedness (a "Payment
     Default"), and the principal amount of any such Indebtedness, together with
     the principal amount of any other such Indebtedness of the Company or any
     Significant Subsidiary under which there has been a Payment Default or the
     maturity of which has been accelerated as provided in clause (y),
     aggregates $5.0 million or more or (y) results in the acceleration (which
     acceleration has not been rescinded) of such Indebtedness prior to its
     express maturity and the principal amount of any such Indebtedness,
     together with the principal amount of any other such Indebtedness under
     which there has been a Payment Default or the maturity of which has been so
     accelerated, aggregates $5.0 million or more;
 
          (vi) failure by the Company or any of its Significant Subsidiaries to
     pay final judgments (other than any judgment as to which a reputable
     insurance company has accepted full liability in writing) aggregating in
     excess of $5.0 million which judgments are not paid, discharged or stayed
     within 45 days after their entry; and
 
                                       38
<PAGE>   41
 
          (vii) certain events of bankruptcy or insolvency with respect to the
     Company or any of its Significant Subsidiaries.
 
     If any Event of Default occurs and is continuing under the Senior Note
Indenture, the Trustee or the holders of at least 25% in principal amount of the
then outstanding Senior Notes may declare all the Senior Notes to be due and
payable immediately. Upon such declaration, the principal of, premium, if any,
and accrued and unpaid interest and Liquidated Damages, if any, on the Senior
Notes shall be due and payable immediately. Notwithstanding the foregoing, in
the case of an Event of Default arising from certain events of bankruptcy or
insolvency with respect to the Company or any of its Significant Subsidiaries,
the foregoing amount shall ipso facto become due and payable without further
action or notice. No premium is payable upon acceleration of the Senior Notes
except that in the case of an Event of Default that is the result of an action
or inaction by the Company or any of its Subsidiaries intended to avoid
restrictions on or premiums related to redemptions of the Senior Notes contained
in the Senior Note Indenture or the Senior Notes. The amount declared due and
payable will include the premium that would have been applicable on a voluntary
prepayment of the Senior Notes. Holders of the Senior Notes may not enforce the
Senior Note Indenture or the Senior Notes except as provided in the Senior Note
Indenture. Subject to certain limitations, holders of a majority in principal
amount of the then outstanding Senior Notes may direct the Trustee in its
exercise of any trust or power. The Trustee may withhold from holders of the
Senior Notes notice of any continuing Default or Event of Default (except a
Default or Event of Default relating to the payments of principal or interest)
if it determines that withholding notice is in such holders' interest.
 
     The holders of a majority in aggregate principal amount of the Senior Notes
then outstanding, by notice to the Trustee, may on behalf of the holders of all
of the Senior Notes, waive any existing Default or Event of Default and its
consequences under the Senior Note Indenture, except a continuing Default or
Event of Default in the payment of interest or Liquidated Damages or premium on,
or the principal of, the Senior Notes.
 
     The Company is required to deliver to the Trustee annually a statement
regarding compliance with the Senior Note Indenture, and the Company is required
upon becoming aware of any Default or Event of Default to deliver to the Trustee
a statement specifying such Default or Event of Default.
 
NO PERSONAL LIABILITY OF DIRECTORS, OFFICERS, EMPLOYEES AND STOCKHOLDERS
 
     No director, officer, employee, incorporator or stockholder of the Company,
as such, shall have any liability for any obligations of the Company under the
Senior Notes or the Senior Note Indenture or for any claim based on, in respect
of, or by reason of such obligations or their creation. Each holder of Senior
Notes by accepting a Senior Note waives and releases all such liability. The
waiver and release are part of the consideration for issuance of the Senior
Notes. Such waiver may not be effective to waive liabilities under the federal
securities laws and it is the view of the Commission that such a waiver is
against public policy.
 
LEGAL DEFEASANCE AND COVENANT DEFEASANCE
 
     The Company may, at its option and at any time, elect to have its
obligations discharged with respect to the outstanding Senior Notes ("Legal
Defeasance"). Such Legal Defeasance means that the Company shall be deemed to
have paid and discharged the entire indebtedness represented by the outstanding
Senior Notes, except for:
 
          (a) the rights of holders of outstanding Senior Notes to receive from
     the trust described below payments in respect of the principal of, premium,
     if any, and interest on and Liquidated Damages with respect to such Senior
     Notes when such payments are due, or on the redemption date, as the case
     may be;
 
          (b) the Company's obligations with respect to the Senior Notes
     concerning issuing temporary Senior Notes, registration of Senior Notes,
     mutilated, destroyed, lost or stolen Senior Notes and the maintenance of an
     office or agency for payment and money for security payments held in trust;
 
          (c) the rights, powers, trust, duties and immunities of the Trustee,
     and the Company's obligations in connection therewith; and
                                       39
<PAGE>   42
 
          (d) the Legal Defeasance provisions of the Senior Note Indenture.
 
          In addition, the Company may, at its option and at any time, elect to
     have the obligations of the Company released with respect to certain
     covenants that are described in the Senior Note Indenture ("Covenant
     Defeasance") and thereafter any omission to comply with such obligations
     shall not constitute a Default or Event of Default with respect to the
     Senior Notes. In the event Covenant Defeasance occurs, certain events (not
     including non payment, bankruptcy, receivership, rehabilitation and
     insolvency events) described under the subheading "Events of Default" will
     no longer constitute an Event of Default with respect to the Senior Notes.
 
     In order to exercise either Legal Defeasance or Covenant Defeasance:
 
          (i) the Company must irrevocably deposit with the Trustee, in trust,
     for the benefit of the holders of the Senior Notes, cash in U.S. dollars,
     non-callable U.S. government obligations, or a combination thereof, in such
     amounts as will be sufficient, in the opinion of a nationally recognized
     firm of independent public accountants selected by the Company, to pay the
     principal of, premium and Liquidated Damages, if any, and interest on the
     outstanding Senior Notes, on the stated maturity or on the applicable
     optional redemption date, as the case may be, of such principal or
     installment of principal of, premium, if any, or interest on or Liquidated
     Damages with respect to the outstanding Senior Notes;
 
          (ii) in the case of Legal Defeasance, the Company must deliver to the
     Trustee an opinion of counsel in the United States reasonably acceptable to
     the Trustee confirming that (A) the Company has received from, or there has
     been published by, the Internal Revenue Service a ruling or (B) since the
     Issue Date, there has been a change in the applicable federal income tax
     law, in either case to the effect that, and based thereon such opinion of
     counsel shall confirm that, the holders of the outstanding Senior Notes
     will not recognize income, gain or loss for federal income tax purposes as
     a result of such Legal Defeasance and will be subject to federal income tax
     on the same amounts, in the same manner and at the same times as would have
     been the case if such Legal Defeasance had not occurred;
 
          (iii) in the case of Covenant Defeasance, the Company must deliver to
     the Trustee an opinion of counsel in the United States reasonably
     acceptable to the Trustee confirming that the holders of the outstanding
     Senior Notes will not recognize income, gain or loss for federal income tax
     purposes as a result of such Covenant Defeasance and will be subject to
     federal income tax on the same amounts, in the same manner and at the same
     times as would have been the case if such Covenant Defeasance had not
     occurred;
 
          (iv) no Default or Event of Default shall have occurred and be
     continuing on the date of such deposit (other than a Default or Event of
     Default resulting from the borrowing of funds to be applied to such
     deposit) or insofar as Events of Default from bankruptcy or insolvency
     events are concerned, at any time in the period ending on the 91st day
     after the date of deposit;
 
          (v) such Legal Defeasance or Covenant Defeasance will not result in a
     breach or violation of, or constitute a default under any material
     agreement or instrument (other than the Senior Note Indenture) to which the
     Company or any of its Subsidiaries is a party or by which the Company or
     any of its Subsidiaries is bound;
 
          (vi) the Company must have delivered to the Trustee an opinion of
     counsel to the effect that after the 91st day (or such other applicable
     date) following the deposit, the trust funds will not be subject to the
     effect of any applicable bankruptcy, insolvency, reorganization or similar
     laws affecting creditors' rights generally;
 
          (vii) the Company must deliver to the Trustee an Officers' Certificate
     stating that the deposit was not made by the Company with the intent of
     preferring the holders of Senior Notes over the other creditors of the
     Company with the intent of defeating, hindering, delaying or defrauding
     creditors of the Company or others; and
 
                                       40
<PAGE>   43
 
          (viii) the Company must deliver to the Trustee an Officers'
     Certificate and an opinion of counsel, each stating that all conditions
     precedent provided for relating to the Legal Defeasance or the Covenant
     Defeasance have been complied with.
 
AMENDMENT, SUPPLEMENT AND WAIVER
 
     Except as provided in the next succeeding paragraph, the Senior Note
Indenture or the Senior Notes may be amended or supplemented with the consent of
the holders of at least a majority in principal amount of the Senior Notes then
outstanding (including consents obtained in connection with a tender offer or
exchange offer for Senior Notes), and any existing default or compliance with
any provision of the Senior Note Indenture or the Senior Notes may be waived
with the consent of the holders of a majority in principal amount of the then
outstanding Senior Notes (including consents obtained in connection with a
tender offer or exchange offer for Senior Notes).
 
     Without the consent of each holder affected, however, an amendment or
waiver may not (with respect to any Senior Note held by a non-consenting
holder):
 
          (i) reduce the principal amount of Senior Notes whose holders must
     consent to an amendment, supplement or waiver;
 
          (ii) reduce the principal or change the fixed maturity of any Senior
     Note or alter the provisions with respect to the redemption of the Senior
     Notes (other than provisions relating to the covenants described under the
     subheadings "Offer to Purchase upon Change of Control" and "Offer to
     Purchase with Excess Asset Sale Proceeds");
 
          (iii) reduce the rate of or change the time for payment of interest on
     any Senior Notes;
 
          (iv) waive a Default or Event of Default in the payment of principal
     of or premium, if any, or interest on the Senior Notes (except a rescission
     of acceleration of the Senior Notes by the holders of at least a majority
     in aggregate principal amount of the Senior Notes and a waiver of the
     payment default that resulted from such acceleration);
 
          (v) make any Senior Note payable in money other than that stated in
     the Senior Notes;
 
          (vi) make any change in the provisions of the Senior Note Indenture
     relating to waivers of past Defaults or the rights of holders of Senior
     Notes to receive payments of principal of, premium, if any, or interest on
     the Senior Notes;
 
          (vii) waive a redemption payment with respect to any Senior Note
     (other than a payment required by one of the covenants described above
     under the subheadings "Offer to Purchase upon Change of Control" and "Offer
     to Purchase with Excess Asset Sale Proceeds"); or
 
          (viii) make any change in the foregoing amendment and waiver
     provisions.
 
     Notwithstanding the foregoing, without the consent of any holder of Senior
Notes, the Company and the Trustee may amend or supplement the Senior Note
Indenture or the Senior Notes:
 
             (a) to cure any ambiguity, defect or inconsistency;
 
             (b) to provide for uncertificated Senior Notes in addition to or in
        place of certificated Senior Notes;
 
             (c) to provide for the assumption of the Company's obligations to
        holders of the Senior Notes in the case of a merger or consolidation;
 
             (d) to make any change that would provide any additional rights or
        benefits to the holders of the Senior Notes or that does not adversely
        affect the legal rights under the Senior Note Indenture of any such
        holder; or
 
             (e) to comply with requirements of the Commission in order to
        effect or maintain the qualification of the Senior Note Indenture under
        the Trust Indenture Act.

CONCERNING THE TRUSTEE
 
     If the Trustee becomes a creditor of the Company, the Senior Note Indenture
limits its rights to obtain payment of claims in certain cases, or to realize on
certain property received in respect of any such claim as security or otherwise.
The Trustee will be permitted to engage in other transactions with the Company;
however, if the Trustee acquires any conflicting interest, it must eliminate
such conflict within 90 days, apply to the Commission for permission to continue
as Trustee or resign.
 
     The holders of a majority in principal amount of the then outstanding
Senior Notes will have the right to direct the time, method and place of
conducting any proceeding for exercising any remedy available to the Trustee,
subject to certain exceptions. The Senior Note Indenture provides that in case
an Event of Default shall occur and be continuing, the Trustee will be required,
in the exercise of its powers, to use the degree of care of a prudent man in the
conduct of his own affairs. Subject to such provisions, the Trustee will be
under no obligation to exercise any of its rights or powers under the Senior
Note Indenture at the request of any holder of Senior Notes, unless such holder
shall have offered to the Trustee security and indemnity satisfactory to it
against any loss, liability or expense.
 
     No holder of any Senior Note will have any right to institute any
proceeding with respect to the Senior Note Indenture or for any remedy
thereunder, unless:
 
          (i) such holder gives to the Trustee written notice of a continuing
     Event of Default;
 
          (ii) holders of at least 25% in principal amount of the then
     outstanding Senior Notes make a written request to pursue the remedy;
 
          (iii) such holders of the Senior Notes provide to the Trustee
     satisfactory indemnity; and
 
          (iv) the Trustee does not comply within 60 days. Otherwise, no holder
     of any Senior Note will have any right to institute any proceeding with
     respect to the Senior Note Indenture or for any remedy thereunder,
 
     except:
 
          (i) a holder of a Senior Note may institute suit for enforcement of
     payment of the principal of and premium, if any, or interest on such Senior
     Note on or after the respective due dates expressed in such Senior Note
     (including upon acceleration thereof); or
 
          (ii) the institution of any proceeding with respect to the Senior Note
     Indenture or any remedy thereunder, including without limitation
     acceleration, by the Holders of a majority in principal amount of the
     outstanding Senior Notes, provided that, upon institution of any proceeding
     or exercise of any remedy such Holders provide the Trustee with prompt
     notice thereof.

REGISTRATION RIGHTS; LIQUIDATED DAMAGES
 
     The following description is a summary of the material provisions of the
Senior Note Registration Rights Agreement. It does not restate that agreement in
its entirety. We urge you to read the Senior Note Registration Rights Agreement
in its entirety because it, and not this description, defines your registration
rights as Holders of these Senior Notes. See "Additional Information."
 
     Pursuant to the Senior Note Registration Rights Agreement, the Company
agreed to file with the SEC a registration statement (the "Senior Exchange Offer
Registration Statement") on the appropriate form under the Securities Act with
respect to an offer to exchange (the "Senior Exchange Offer") the 9 1/2% Senior
Notes for 9 1/2% Series B Senior Notes. Upon the effectiveness of the Senior
Exchange Offer
 
                                       42
<PAGE>   45
 
Registration Statement, the Company will offer to the holders of Transfer
Restricted Securities pursuant to the Senior Exchange Offer who are able to make
certain representations the opportunity to exchange their Transfer Restricted
Securities for a new issue of senior notes of the Company (the "9 1/2% Series B
Senior Notes") registered under the Securities Act, with terms substantially
identical to those of the 9 1/2% Senior Notes.
 
     If:
 
          (i) the Company is not:
 
             (a) required to file the Senior Exchange Offer Registration
        Statement; or
 
             (b) permitted to consummate the Senior Exchange Offer because the
        Senior Exchange Offer is not permitted by applicable law or Commission
        policy; or
 
          (ii) any holder of Transfer Restricted Securities notifies the Company
     within the specified time period that:
 
             (a) it is prohibited by law or Commission policy from participating
        in the Senior Exchange Offer,
 
             (b) it may not resell the 9 1/2% Series B Senior Notes acquired by
        it in the Senior Exchange Offer to the public without delivering a
        prospectus and the prospectus contained in the Senior Exchange Offer
        Registration Statement is not appropriate or available for such resales;
        or
 
             (c) it is a broker-dealer and owns 9 1/2% Senior Notes acquired
        directly from the Company or an affiliate of the Company,
 
          the Company will file with the Commission a shelf registration
     statement (the "Senior Notes Shelf Registration Statement") to cover
     resales of the Senior Notes by the Holders thereof who satisfy certain
     conditions relating to the provision of information in connection with the
     Senior Notes Shelf Registration Statement.
 
     The Company will use its best efforts to cause the applicable registration
statement to be declared effective as promptly as possible by the Commission.
 
     For purposes of the foregoing, "Transfer Restricted Securities" means each
9 1/2% Senior Note until:
 
          (i) the date on which such 9 1/2% Senior Note has been exchanged by a
     Person other than a broker-dealer for a 9 1/2% Series B Senior Note in the
     Senior Exchange Offer;
 
          (ii) following the exchange by a broker-dealer in the Senior Exchange
     Offer of a 9 1/2% Senior Note for a 9 1/2% Series B Senior Note, the date
     on which such 9 1/2% Series B Senior Note is sold to a purchaser who
     receives from such broker-dealer on or prior to the date of such sale a
     copy of the prospectus contained in the Senior Exchange Offer Registration
     Statement;
 
          (iii) the date on which such 9 1/2% Senior Note has been effectively
     registered under the Securities Act and disposed of in accordance with the
     Senior Notes Shelf Registration Statement; or
 
          (iv) the date on which such 9 1/2% Senior Note may be distributed to
     the public pursuant to Rule 144 under the Securities Act.
 
          The Senior Note Registration Rights Agreement provides that:
 
          (i) unless the Senior Exchange Offer would not be permitted by
     applicable law or Commission policy, the Company will file a Senior
     Exchange Offer Registration Statement with the Commission on or prior to 60
     days after the Issue Date;
 
          (ii) unless the Senior Exchange Offer would not be permitted by
     applicable law or Commission policy, the Company will use its best efforts
     to have the Senior Exchange Offer Registration Statement declared effective
     by the Commission on or prior to 180 days after the Issue Date;
 
                                       43
<PAGE>   46
 
          (iii) unless the Senior Exchange Offer would not be permitted by
     applicable law or Commission policy, the Company will
 
             (a) upon the effectiveness of the Senior Exchange Offer
        Registration Statement, commence the Senior Exchange Offer and
 
             (b) use its best efforts to issue on or prior to 30 business days
        after the date on which the Senior Exchange Offer Registration Statement
        was declared effective by the Commission, 9 1/2% Series B Senior Notes
        in exchange for all 9 1/2% Senior Notes tendered prior thereto in the
        Senior Exchange Offer; and
 
          (iv) if obligated to file the Senior Notes Shelf Registration
     Statement, the Company will use its best efforts to file the Senior Notes
     Shelf Registration Statement with the Commission on or prior to 60 days
     after such filing obligation arises (and, if the Senior Exchange Offer is
     not permitted by applicable law or Commission policy, in any event within
     150 days after the Issue Date) and to cause the Senior Notes Shelf
     Registration Statement to be declared effective by the Commission on or
     prior to 180 days after such obligation arises (and, if the Senior Exchange
     Offer is not be permitted by applicable law or Commission policy, in any
     event within 270 days after the Issue Date).
 
          If:
 
             (a) the Company fails to file any of the registration statements
        required by the Senior Note Registration Rights Agreement on or before
        the date specified for such filing;
 
             (b) any of such registration statements is not declared effective
        by the Commission on or prior to the date specified for such
        effectiveness (the "Senior Note Effectiveness Target Date");
 
             (c) the Company fails to consummate the Senior Exchange Offer
        within 30 business days of the Senior Note Effectiveness Target Date
        with respect to the Senior Exchange Offer Registration Statement; or
 
             (d) the Senior Notes Shelf Registration Statement or the Senior
        Exchange Offer Registration Statement is declared effective but
        thereafter ceases to be effective or usable in connection with resales
        of Transfer Restricted Securities during the periods specified in the
        Senior Note Registration Rights Agreement, provided, that the Company
        will have the option of suspending the effectiveness of the Senior Notes
        Shelf Registration Statement or the Senior Exchange Offer Registration
        Statement, without becoming obligated to pay Liquidated Damages for
        periods of up to a total of 60 days in any calendar year if the Board of
        Directors of the Company determines that compliance with the disclosure
        obligations necessary to maintain the effectiveness of the Senior Notes
        Shelf Registration Statement at such time could reasonably be expected
        to have an adverse effect on the Company or a pending corporate
        transaction (each such event referred to in clauses (a) through (d)
        above a "Senior Note Registration Default"),
 
          then the Company will pay liquidated damages ("Liquidated Damages") to
     each Holder of Transfer Restricted Securities, with respect to the first
     90-day period immediately following the occurrence of such Senior Note
     Registration Default, in an amount equal to $.05 per week per $1,000
     principal amount of Senior Notes constituting Transfer Restricted
     Securities held by such Holder.
 
     The amount of the Liquidated Damages will increase by an additional $.05
per week per $1,000 principal amount of Senior Notes constituting Transfer
Restricted Securities with respect to each subsequent 90-day period until all
Senior Note Registration Defaults have been cured, up to a maximum amount of
Liquidated Damages of $.50 per week per $1,000 principal amount of Senior Notes
constituting Transfer Restricted Securities.
 
     All accrued Liquidated Damages will be paid by the Company on each Interest
Payment Date to the Global Senior Note Holder by wire transfer of immediately
available funds or by federal funds check and to Holders of Certificated
Securities by mailing checks to their registered addresses.
 
                                       44
<PAGE>   47
 
     Following the cure of all Senior Note Registration Defaults, the accrual of
Liquidated Damages will cease.
 
     Holders of Senior Notes will be required to make certain representations to
the Company (as described in the Senior Note Registration Rights Agreement) in
order to participate in the Senior Exchange Offer and will be required to
deliver information to be used in connection with the Senior Notes Shelf
Registration Statement and to provide comments on the Senior Notes Shelf
Registration Statement within the time periods set forth in the Senior Note
Registration Rights Agreement in order to have their Senior Notes included in
the Senior Notes Shelf Registration Statement and benefit from the provisions
regarding Liquidated Damages set forth above.
 
BOOK-ENTRY, DELIVERY AND FORM
 
     Except as set forth in the next paragraph, the 9 1/2% Series B Senior Notes
may be issued in the form of one or more global certificates (the "Global Senior
Notes"). The Global Senior Notes will be deposited with, or on behalf of, The
Depository Trust Company (the "Depositary") and registered in the name of Cede &
Co., as nominee of the Depositary (such nominee being referred to herein as the
"Global Senior Note Holder").
 
     Senior Notes that are issued as described below under the subheading
"Certificated Securities" will be issued in the form of registered definitive
certificates (the "Certificated Securities"). Upon the transfer of Certificated
Securities, such Certificated Securities may, unless all Global Senior Notes
have previously been exchanged for Certificated Securities, be exchanged for an
interest in the Global Senior Note representing the principal amount of Senior
Notes being transferred, subject to the transfer restrictions set forth in the
Senior Note Indenture.
 
     The Depositary is a limited-purpose trust company that was created to hold
securities for its participating organizations (collectively, the "Participants"
or the "Depositary's Participants") and to facilitate the clearance and
settlement of transactions in such securities between Participants through
electronic book-entry changes in accounts of its Participants. The Depositary's
Participants include securities brokers and dealers (including the initial
purchasers), banks and trust companies, clearing corporations and certain other
organizations. Access to the Depositary's system is also available to other
entities such as banks, brokers, dealers and trust companies (collectively, the
"Indirect Participants" or the "Depositary's Indirect Participants") that clear
through or maintain a custodial relationship with a Participant, either directly
or indirectly. Persons who are not Participants may beneficially own securities
held by or on behalf of the Depositary only through the Depositary's
Participants or the Depositary's Indirect Participants.
 
     The Company expects that pursuant to procedures established by the
Depositary:
 
          (i) upon deposit of the Global Senior Notes, the Depositary will
     credit the accounts of Participants designated by the initial purchasers
     with portions of the principal amount of the Global Senior Notes; and
 
          (ii) ownership of the Senior Notes evidenced by the Global Senior
     Notes will be shown on, and the transfer of ownership thereof will be
     effected only through, records maintained by the Depositary (with respect
     to the interests of the Depositary's Participants), the Depositary's
     Participants and the Depositary's Indirect Participants.
 
     Prospective purchasers are advised that the laws of some states require
that certain persons take physical delivery in definitive form of securities
that they own. Consequently, the ability to transfer Senior Notes evidenced by
the Global Senior Note will be limited to such extent.
 
     So long as the Global Senior Note Holder is the registered owner of any
Senior Notes, the Global Senior Note Holder will be considered the sole Holder
under the Senior Note Indenture of any Senior Notes evidenced by the Global
Senior Notes. Beneficial owners of Senior Notes evidenced by the Global Senior
Notes will not be considered the owners or Holders thereof under the Senior Note
Indenture for any purpose, including with respect to the giving of any
directions, instructions or approvals to the Trustee thereunder. Neither the
Company nor the Trustee will have any responsibility or liability for any aspect
of the records of
 
                                       45
<PAGE>   48
 
the Depositary or for maintaining, supervising or reviewing any records of the
Depositary relating to the Senior Notes.
 
     Payments in respect of the principal of, premium, if any, interest and
Liquidated Damages, if any, on any Senior Notes registered in the name of the
Global Senior Note Holder on the applicable record date will be payable by the
Trustee to or at the direction of the Global Senior Note Holder in its capacity
as the registered Holder under the Senior Note Indenture. Under the terms of the
Senior Note Indenture, the Company and the Trustee may treat the persons in
whose names Senior Notes, including the Global Senior Notes, are registered as
the owners thereof for the purpose of receiving such payments. Consequently,
neither the Company nor the Trustee has or will have any responsibility or
liability for the payment of such amounts to beneficial owners of Senior Notes.
The Company believes, however, that it is currently the policy of the Depositary
to immediately credit the accounts of the relevant Participants with such
payments, in amounts proportionate to their respective holdings of beneficial
interests in the relevant security as shown on the records of the Depositary.
Payments by the Depositary's Participants and the Depositary's Indirect
Participants to the beneficial owners of the Senior Notes will be governed by
standing instructions and customary practice and will be the responsibility of
the Depositary's Participants or the Depositary's Indirect Participants.
 
     Certificated Securities
 
     Subject to certain conditions, any person having a beneficial interest in a
Global Senior Note may, upon request to the Trustee, exchange such beneficial
interest for Senior Notes in the form of Certificated Securities. Upon any such
issuance, the Trustee is required to register such Certificated Securities in
the name of, and cause the same to be delivered to, such person or persons (or
the nominee of any thereof).
 
     In addition, if:
 
          (i) the Company notifies the Trustee in writing that the Depositary is
     no longer willing or able to act as a depositary and a successor depositary
     is not appointed by the Company within 120 days; or
 
          (ii) the Company, at its option, notifies the Trustee in writing that
     it elects to cause the issuance of Senior Notes in the form of Certificated
     Securities under the Senior Note Indenture,
 
          then, upon surrender by the Global Senior Note Holder of its Global
     Senior Note, Senior Notes in such form will be issued to each person that
     the Global Senior Note Holder and the Depositary identify as being the
     beneficial owner of the related Senior Notes.
 
     Neither the Company nor the Trustee will be liable for any delay by the
Global Senior Note Holder or the Depositary in identifying the beneficial owners
of Senior Notes and the Company and the Trustee may conclusively rely on, and
will be protected in relying on, instructions from the Global Senior Note Holder
or the Depositary for all purposes.
 
SAME DAY SETTLEMENT AND PAYMENT
 
     The Company will make payments in respect of the Senior Notes represented
by the Global Senior Notes (including principal, premium, if any, interest and
Liquidated Damages, if any) by wire transfer of immediately available funds to
the accounts specified by the Global Senior Note Holder. With respect to Senior
Notes in certificated form, the Company will make all payments of principal,
premium, if any, interest and Liquidated Damages, if any, by wire transfer of
immediately available funds to the accounts specified by the Holders thereof or,
if no such account is specified, by mailing a check to each such Holder's
registered address. The Senior Notes represented by the Global Senior Notes are
expected to be eligible to trade in the Depository's Same-Day Funds Settlement
System, and any permitted secondary market trading activity in such Senior Notes
will, therefore, be required by the Depositary to be settled in immediately
available funds. The Company expects that secondary trading in any certificated
Senior Notes will also be settled in immediately available funds.

          (1) if the Company or any Subsidiary of the Company has incurred any
     Indebtedness (including Acquired Debt) or if the Company has issued any
     Disqualified Stock or if any Subsidiary of the Company has issued any
     Preferred Stock since the beginning of such period that remains outstanding
     on the date of such determination or if the transaction giving rise to the
     need to calculate the Consolidated Cash Flow Leverage Ratio is an
     incurrence of Indebtedness (including Acquired Debt) or the issuance of
     Disqualified Stock by the Company, Consolidated EBITDA and Consolidated
     Indebtedness for such period will be calculated after giving effect on a
     pro forma basis to:
 
             (A) such Indebtedness, Disqualified Stock or Preferred Stock, as
        applicable, as if such Indebtedness had been incurred or such stock had
        been issued on the first day of such period;
 
             (B) the discharge of any other Indebtedness repaid, repurchased,
        defeased or otherwise discharged with the proceeds of such new
        Indebtedness or sale of stock as if such discharge had occurred on the
        first day of such period; and
 
             (C) the interest income realized by the Company or its Subsidiaries
        on the proceeds of such Indebtedness or of such stock sale, to the
        extent not yet applied at the date of determination, assuming such
        proceeds earned interest at the rate in effect on the date of
        determination from the first day of such period through such date of
        determination;
 
          (2) if since the beginning of such period the Company or any
     Subsidiary of the Company has made any sale of assets (including, without
     limitation, any Asset Sales or pursuant to any Sale and Leaseback
     Transaction), Consolidated EBITDA for such period will be:
 
             (A) reduced by an amount equal to Consolidated EBITDA (if positive)
        directly attributable to the assets which are the subject of such sale
        of assets for such period; or
 
             (B) increased by an amount equal to Consolidated EBITDA (if
        negative) directly attributable thereto for such period; and
 
                                       48
<PAGE>   51
 
             (3) if since the beginning of such period the Company or any
        Subsidiary of the Company (by merger or otherwise) has made an
        Investment in any Subsidiary of the Company (or any Person which becomes
        a Subsidiary of the Company) or has made an acquisition of assets,
        including, without limitation, any acquisition of assets occurring in
        connection with a transaction causing a calculation of Consolidated
        EBITDA to be made hereunder, which constitutes all or substantially all
        of an operating unit of a business, Consolidated EBITDA for such period
        will be calculated after giving pro forma effect thereto (including the
        incurrence of any Indebtedness (including Acquired Debt)) as if such
        Investment or acquisition occurred on the first day of such period.
 
          For purposes of this definition, whenever pro forma effect is to be
     given to an acquisition of assets, the pro forma calculations will be
     determined in good faith by a responsible financial or accounting Officer
     of the Company, provided, however, that such Officer shall assume:
 
             (i) the historical sales and gross profit margins associated with
        such assets for any consecutive 12-month period ended prior to the date
        of purchase (provided that the first month of such 12-month period will
        be no more than 18 months prior to such date of purchase); and
 
             (ii) other expenses as if such assets had been owned by the Company
        since the first day of such period. If any Indebtedness (including,
        without limitation, Acquired Debt) bears a floating rate of interest and
        is being given pro forma effect, the interest on such Indebtedness will
        be calculated as if the rate in effect on the date of determination had
        been the applicable rate for the entire period.
 
     "Consolidated EBITDA" as of any date of determination means the
Consolidated Net Income for such period (but without giving effect to

Income:
 
          (i) provision for taxes based on income or profits of such Person and
     its Subsidiaries for such period;
 
          (ii) Consolidated Interest Expense;
 
          (iii) depreciation, amortization (including amortization of goodwill
     and other intangibles); and
 
          (iv) other non-cash charges (excluding any such non-cash charge to the
     extent that it represents an accrual of or reserve for cash charges in any
     future period or amortization of a prepaid cash expense that was paid in a
     prior period and excluding non-cash interest and dividend income) of such
     Person and its Subsidiaries for such period, in each case, on a
     consolidated basis and determined in accordance with GAAP.
 
     Notwithstanding the foregoing, the provision for taxes on the income or
profits of, and the depreciation, amortization, interest expense, and other
non-cash charges of, a Subsidiary of the referent Person shall be added to
Consolidated Net Income to compute Consolidated EBITDA only to the extent (and
in same proportion) that the Net Income of such Subsidiary was included in
calculating the Consolidated Net Income of such Person and only if a
corresponding amount would be permitted at the date of determination to be
dividended to the Company by such Subsidiary, or loaned to the Company by any

     amortization of original issue discount, amortization of debt issuance
     costs, and non-cash interest payments on any Indebtedness, the
 
                                       49
<PAGE>   52
 
     interest portion of any deferred payment obligation and after taking into
     account the effect of elections made under any Interest Rate Agreement
     however denominated with respect to such Indebtedness);
 
          (b) the amount of Redeemable Dividends (to the extent not already
     included in Indebtedness in determining Consolidated Interest Expense for
     the relevant period); and
 
          (c) the interest component of rentals in respect of any Capital Lease
     Obligation paid, in each case whether accrued or scheduled to be paid or
     accrued by such Person during such period to the extent such amounts were
     deducted in computing Consolidated Net Income, determined on a consolidated
     basis in accordance with GAAP. For purposes of this definition interest on
     a Capital Lease Obligation shall be deemed to accrue at an interest rate
     reasonably determined by such Person to be the rate of interest implicit in
     such Capital Lease Obligation in accordance with GAAP consistently applied.

          (ii) the Net Income of any Subsidiary shall be excluded to the extent
     that the declaration or payment of dividends or other distributions by that
     Subsidiary of that Net Income is not at the date of determination permitted
     without any prior governmental approval (which has not been obtained) or,
     directly or indirectly, by operation of the terms of its charter or any
     agreement, instrument, judgment, decree, order, statute, rule or
     governmental regulation applicable to that Subsidiary or its stockholders;
 
          (iii) the Net Income of any Person acquired in a pooling of interests
     transaction for any period prior to the date of such acquisition shall be

invest, such Investment shall be deemed not made to the extent of such release

                  DESCRIPTION OF THE SENIOR SUBORDINATED NOTES
 
     You can find the definitions of certain terms used in this description
under the subheading "Certain Definitions." In this description, the word
"Company" refers only to Intermedia Communications Inc. and not to any of its
subsidiaries and term Senior Subordinated Notes refers only to the 12 1/4%
Senior Subordinated Notes and 12 1/4% Series B Senior Subordinated Notes and not
the Senior Notes.
 
     The Company will issue the 12 1/4% Series B Senior Subordinated Notes under
an indenture (the "Senior Subordinated Note Indenture") between itself and
SunTrust Bank, Central Florida, National Association, as trustee (the
"Trustee"). The terms of the Senior Subordinated Notes include those stated in
the Senior Subordinated Note Indenture and those made part of the Senior
Subordinated Note Indenture by reference to the Trust Indenture Act of 1939, as
amended (the "Trust Indenture Act"). Certain rights of the holders of the Senior
Subordinated Notes are all set forth in a registration rights agreement between
the Company and the initial purchasers of the Senior Subordinated Notes (the
"Senior Subordinated Note Registration Rights Agreement").
 
     The following description is a summary of the material provisions of the
Senior Subordinated Note Indenture and the Senior Subordinated Note Registration
Rights Agreement. It does not restate those agreements in their entirety. We
urge you to read the Senior Subordinated Note Indenture and the Senior
Subordinated Note Registration Rights Agreement because they, and not this
description, define your rights as holders of the Senior Subordinated Notes.
Copies of the Senior Subordinated Note Indenture and the Senior Subordinated
Note Registration Rights Agreement are available as set forth below under the
subheading "Additional Information." Certain defined terms used in this
description but not defined below under the subheading "Certain Definitions"
have the meanings assigned to them in the Senior Subordinated Note Indenture.
 
BRIEF DESCRIPTION OF THE SENIOR SUBORDINATED NOTES
 
     The Senior Subordinated Notes:
 
           - are general unsecured obligations of the Company;
 
           - are subordinated in right of payment to all existing and future
             Senior Debt of the Company, including, without limitation, the
             Existing Senior Notes and the Senior Notes; and
 
           - are pari passu in right of payment with any future senior
             subordinated Indebtedness of the Company.
 
     Certain of the Company's operations are conducted through its Subsidiaries
and, therefore, the Company is dependent upon the cash flow of its Subsidiaries
to meet its obligations, including its obligations under the Senior Subordinated
Notes. The 12 1/4% Senior Subordinated Notes are, and the 12 1/4% Series B
Senior Subordinated Notes will be, effectively subordinated to all indebtedness
and other liabilities and commitments (including trade payables and lease
obligations) of the Company's Subsidiaries. Any right of the Company to receive
assets of any of its Subsidiaries upon the latter's liquidation or
reorganization (and the consequent right of the Holders of the Senior
Subordinated Notes to participate in those assets) will be effectively
subordinated to the claims of that Subsidiary's creditors, except to the extent
that the Company is itself recognized as a creditor of such Subsidiary, in which
case the claims of the Company would still be subordinate to any security in the
assets of such Subsidiary and any indebtedness of such Subsidiary senior to that
held by the Company. As of December 31, 1998, on a pro forma basis after giving
effect to the offering of the Senior Notes and the Senior Subordinated Notes,
the Company would have had approximately $3.1 billion of total indebtedness
outstanding, including trade payables and approximately $88.1 million of
indebtedness and other liabilities of the Company's Subsidiaries. Senior
indebtedness would have accounted for approximately $2.1 billion of such total
indebtedness.
 
PRINCIPAL, MATURITY AND INTEREST
 
     The Senior Subordinated Note Indenture provides for the issuance by the
Company of Senior Subordinated Notes with a maximum aggregate principal amount
at maturity of $364.0 million. The Company
 
                                       59
<PAGE>   62
 
will issue 12 1/4% Series B Senior Subordinated Notes in denominations of $1,000
and integral multiples of $1,000. The 12 1/4% Series B Senior Subordinated Notes
will mature on March 1, 2009.
 
     The 12 1/4% Senior Subordinated Notes were issued at a substantial discount
from their principal amount at maturity, to generate gross proceeds of
approximately $200.4 million. Until March 1, 2004, interest will not accrue or
be payable on the Senior Subordinated Notes, but the Accreted Value will accrete
(representing the amortization of original issue discount) between the date of
issuance and March 1, 2004, on a semi-annual bond equivalent basis using a
360-day year composed of twelve 30-day months such that the Accreted Value shall
be equal to the full principal amount at maturity of the Senior Subordinated
Notes on March 1, 2004. After March 1, 2004, interest on the Senior Subordinated
Notes will accrue at the rate of 12 1/4% per annum and will be payable
semi-annually in cash in arrears on March 1 and September 1, commencing on
September 1, 2004. The Company will make each interest payment to the Holders of
record on the immediately preceding February 15 and August 15.
 
     Interest on the Senior Subordinated Notes will accrue from March 1, 2004
or, if interest has already been paid, from the date it was most recently paid.
Interest will be computed on the basis of a 360-day year comprised of twelve
30-day months.
 
PAYING AGENT AND REGISTRAR FOR THE SENIOR SUBORDINATED NOTES
 
     The Trustee will initially act as Paying Agent and Registrar. The Company
may change the Paying Agent or Registrar without prior notice to the Holders,
and the Company or any of its Subsidiaries may act as Paying Agent or Registrar.
 
TRANSFER AND EXCHANGE
 
     A Holder may transfer or exchange Senior Subordinated Notes in accordance
with the Senior Subordinated Note Indenture. The Registrar and the Trustee may
require a Holder, among other things, to furnish appropriate endorsements and
transfer documents and the Company may require a Holder to pay any taxes and
fees required by law or permitted by the Senior Subordinated Note Indenture. The
Company is not required to transfer or exchange any Senior Subordinated Note
selected for redemption. Also, the Company is not required to transfer or
exchange any Senior Subordinated Note for a period of 15 days before a selection
of Senior Subordinated Notes to be redeemed.
 
     The registered Holder of a Senior Subordinated Note will be treated as the
owner of it for all purposes.
 
SUBORDINATION
 
     The payment of principal, interest and premium and Liquidated Damages, if
any, on the Senior Subordinated Notes will be subordinated to the prior payment
in full of all Senior Debt of the Company, including Senior Debt incurred after
the date of the Senior Subordinated Note Indenture.
 
     The holders of Senior Debt will be entitled to receive payment in full of
all Obligations due in respect of Senior Debt (including interest after the
commencement of any bankruptcy proceeding at the rate specified in the
applicable Senior Debt) before the Holders of Senior Subordinated Notes will be
entitled to receive any payment with respect to the Senior Subordinated Notes
(except that Holders of Senior Subordinated Notes may receive and retain
Permitted Junior Securities and payments made from the trust described under the
subheading "Legal Defeasance and Covenant Defeasance"), in the event of any
distribution to creditors of the Company:
 
          (1) in a liquidation or dissolution of the Company;
 
          (2) in a bankruptcy, reorganization, insolvency, receivership or
     similar proceeding relating to the Company or its property;
 
          (3) in an assignment for the benefit of creditors; or
 
          (4) in any marshaling of the Company's assets and liabilities.
 
                                       60
<PAGE>   63
 
     The Company also may not make any payment in respect of the Senior
Subordinated Notes (except in Permitted Junior Securities or from the trust
described under the subheading "Legal Defeasance and Covenant Defeasance") if:
 
          (1) a payment default on Designated Senior Debt occurs and is
     continuing beyond any applicable grace period; or
 
          (2) any other default occurs and is continuing on any series of
     Designated Senior Debt that permits holders of that series of Designated
     Senior Debt to accelerate its maturity and the Trustee receives a notice of
     such default (a "Payment Blockage Notice") from the Company or the holders
     of any Designated Senior Debt.
 
     Payments on the Senior Subordinated Notes may and shall be resumed:
 
          (1) in the case of a payment default, upon the date on which such
     default is cured or waived; and
 
          (2) in case of a nonpayment default, the earlier of the date on which
     such nonpayment default is cured or waived or 179 days after the date on
     which the applicable Payment Blockage Notice is received, unless the
     maturity of any Designated Senior Debt has been accelerated.
 
     No new Payment Blockage Notice may be delivered unless and until:
 
          (1) 360 days have elapsed since the delivery of the immediately prior
     Payment Blockage Notice; and
 
          (2) all scheduled payments of principal, interest and premium and
     Liquidated Damages, if any, on the Senior Subordinated Notes that have come
     due have been paid in full in cash.
 
     No nonpayment default that existed or was continuing on the date of
delivery of any Payment Blockage Notice to the Trustee shall be, or be made, the
basis for a subsequent Payment Blockage Notice unless such default shall have
been cured or waived for a period of not less than 90 days.
 
     If the Trustee or any Holder of the Senior Subordinated Notes receives a
payment in respect of the Senior Subordinated Notes (except in Permitted Junior
Securities or from the trust described under the subheading "Legal Defeasance
and Covenant Defeasance") when:
 
          (1) the payment is prohibited by these subordination provisions; and
 
          (2) the Trustee or the Holder has actual knowledge that the payment is
     prohibited;
 
          the Trustee or the Holder, as the case may be, shall hold the payment
     in trust for the benefit of the holders of Senior Debt. Upon the proper
     written request of the holders of Senior Debt, the Trustee or the Holder,
     as the case may be, shall deliver the amounts in trust to the holders of
     Senior Debt or their proper representative.
 
     The Company must promptly notify holders of Senior Debt if payment of the
Senior Subordinated Notes is accelerated because of an Event of Default.
 
     As a result of the subordination provisions described above, in the event
of a bankruptcy, liquidation or reorganization of the Company, Holders of Senior
Subordinated Notes may recover less ratably than creditors of the Company who
are holders of Senior Debt. See "Risk Factors -- Subordination of the Senior
Subordinated Notes."
 
     "Designated Senior Debt" means:
 
          (1) any Indebtedness outstanding under a Credit Facility; and
 
          (2) after payment in full of all Obligations under any Credit
     Facility, any other Senior Debt permitted under the Senior Subordinated
     Note Indenture the principal amount of which is $25.0 million or more.

     Indenture.
 
     "Senior Debt" means:
 
          (1) all Indebtedness of the Company outstanding under any Credit

     under the terms of the Senior Subordinated Note Indenture, unless the
     instrument under which such Indebtedness is incurred expressly provides
     that it is on a parity with or subordinated in right of payment to the
     Senior Subordinated Notes; and

not include:
 
          (1) any liability for federal, state, local or other taxes owed or
     owing by the Company;
 
          (2) any Indebtedness of the Company to any of its Subsidiaries or
     other Affiliates;
 
          (3) any trade payables; or
 
          (4) the portion of any Indebtedness that is incurred in violation of
     the Senior Subordinated Note Indenture.

     In the event of the sale by the Company prior to March 1, 2002 of its
Capital Stock (other than Disqualified Stock) (i) to a Strategic Investor in a
single transaction or series of related transactions for an aggregate purchase
price equal to or exceeding $50.0 million or (ii) in one or more Public
Offerings (each of clauses (i) and (ii), a "Qualified Equity Offering"), up to a
maximum of 25% of the aggregate principal amount at maturity of the Senior
Subordinated Notes originally issued will, at the option of the Company, be
redeemable from the net cash proceeds of such sale or sales (but only to the
extent such proceeds consist of cash or readily marketable cash equivalents
received in respect of the Capital Stock, other than Disqualified
 
                                       62

Stock, so sold) at a redemption price equal to 112.25% of the Accreted Value
thereof plus accrued and unpaid Liquidated Damages, if any, thereon to the
redemption date, provided that:
 
          (1) at least 75% of the aggregate principal amount at maturity of the
     Senior Subordinated Notes originally issued remains outstanding immediately
     after the occurrence of such redemption; and
 
          (2) such redemption occurs within 90 days of the date of the closing
     of each such sale.
 
MANDATORY REDEMPTION
 
     Except as set forth below under the captions "Offer to Purchase Upon Change
of Control" and "Offer to Purchase with Excess Asset Sale Proceeds," the Company
will not be required to make mandatory redemption or sinking fund payments with
respect to the Senior Subordinated Notes.
 
OFFER TO PURCHASE UPON CHANGE OF CONTROL
 
     Upon the occurrence of a Change of Control, the Company will be required to
make an offer (the "Change of Control Offer") to each holder of Senior
Subordinated Notes to repurchase all or any part (equal to $1,000 or an integral
multiple thereof) of such holder's Senior Subordinated Notes at a purchase price
equal to 101% of the Accreted Value thereof on the date of purchase (if such
date of purchase is prior to March 1, 2004) or 101% of the aggregate principal
amount thereof (if such date of purchase is on or after March 1, 2004) plus
accrued and unpaid interest and Liquidated Damages, if any, thereon to the date
of purchase (the "Change of Control Payment"). The Change of Control Offer must
be commenced within 30 days following a Change of Control, must remain open for
at least 30 and not more than 40 days (unless required by applicable law) and
must comply with the requirements of Rule 14e-1 under the Exchange Act and any
other applicable securities laws and regulations.
 
     Except as described above with respect to a Change of Control, the Senior
Subordinated Note Indenture will not contain provisions that permit the holders
of the Senior Subordinated Notes to require that the Company repurchase or
redeem the Senior Subordinated Notes in the event of a takeover,
recapitalization or similar transaction.
 
     Due to the leveraged structure of the Company, the subordination of the
Senior Subordinated Notes to the Existing Senior Notes and the Senior Notes and
the effective subordination of the Senior Subordinated Notes to secured
Indebtedness of the Company and Indebtedness of the Company's Subsidiaries, the
Company may not have sufficient funds available to purchase the Senior
Subordinated Notes tendered in response to a Change of Control Offer. In
addition, the Existing Senior Notes or other agreements relating to Indebtedness
of the Company's Subsidiaries may contain prohibitions or restrictions on the
Company's ability to effect a Change of Control Payment.
 
     The definition of Change of Control includes a phrase relating to the sale,
lease, transfer, conveyance or other disposition of "all or substantially all"
of the Company's assets. Although there is a developing body of case law
interpreting the phrase "substantially all," there is no precise established
definition of the phrase under applicable law. Accordingly, the ability of a
holder of Senior Subordinated Notes to require the Company to repurchase such
Senior Subordinated Notes as a result of a sale, lease, transfer, conveyance or
other disposition of less than all of the assets of the Company to another
Person may be uncertain.
 
     Prior to complying with any of the provisions of this "Change of Control"
covenant, but in any event within 90 days following a Change of Control, the
Company will either repay all outstanding Senior Debt or obtain the requisite
consents, if any, under all agreements governing outstanding Senior Debt to
permit the repurchase of Senior Subordinated Notes required by this covenant.
 
OFFER TO PURCHASE WITH EXCESS ASSET SALE PROCEEDS
 
     When the cumulative amount of Excess Proceeds (as defined below under the
subheading "Certain Covenants -- Asset Sales") exceeds $10.0 million, the
Company will make an offer to all holders of Senior Subordinated Notes and Pari
Passu Notes (an "Excess Proceeds Offer"), to purchase the maximum principal
amount and/or accreted value as applicable of Senior Subordinated Notes and Pari
Passu Notes that may be purchased out of such Excess Proceeds, at an offer price
in cash in an amount equal to 100% of the Accreted
                                       63
<PAGE>   66
 
Value (if such date of purchase is prior to March 1, 2004) or 100% of the
outstanding principal amount (if such date of purchase is on or after March 1,
2004) of the Senior Subordinated Notes and 100% of the accreted value or 100% of
the outstanding principal amount, as applicable, of the Pari Passu Notes, plus
accrued and unpaid interest and Liquidated Damages thereon, if any, to the date
fixed for the closing of such offer, in accordance with the procedures specified
in the Senior Subordinated Note Indenture.
 
     If the aggregate principal amount and/or accreted value, as the case may
be, of Senior Subordinated Notes and Pari Passu Notes surrendered by holders
thereof exceeds the amount of Excess Proceeds, the Trustee will select the
Senior Subordinated Notes and Pari Passu Notes to be purchased on a pro rata
basis. To the extent that the aggregate amount of Senior Subordinated Notes and
Pari Passu Notes tendered pursuant to an Excess Proceeds Offer is less than the
amount of Excess Proceeds, the Company may use such deficiency for general
purposes. Upon completion of an Excess Proceeds Offer, the amount of Excess
Proceeds will be reset at zero.
 
SELECTION OF SENIOR SUBORDINATED NOTES FOR REDEMPTION OR OFFERS TO PURCHASE
 
     If less than all of the Senior Subordinated Notes are to be redeemed at any
time, the Trustee will select Senior Subordinated Notes for redemption as
follows:
 
          (1) if the Senior Subordinated Notes are listed, in compliance with
     the requirements of the principal national securities exchange on which the
     Senior Subordinated Notes are listed; or
 
          (2) if the Senior Subordinated Notes are not so listed, on a pro rata
     basis, by lot or by such method as the Trustee shall deem fair and
     appropriate.
 
     No Senior Subordinated Notes of $1,000 or less shall be redeemed in part.
Notices of redemption shall be mailed by first class mail at least 30 but not
more than 60 days before the redemption date to each holder of Senior
Subordinated Notes to be redeemed at its registered address. Notices of
redemption may not be conditional.
 
     If any Senior Subordinated Note is to be redeemed in part only, the notice
of redemption that relates to that Senior Subordinated Note shall state the
portion of the principal amount thereof to be redeemed. A new Senior
Subordinated Note in principal amount equal to the unredeemed portion of the
original Senior Subordinated Note will be issued in the name of the Holder
thereof upon cancellation of the original Senior Subordinated Note. Senior
Subordinated Notes called for redemption become due on the date fixed for
redemption. On and after the redemption date, interest ceases to accrete or
accrue on the Senior Subordinated Notes or portions of them called for
redemption.

<PAGE>   67
 
          (iv) make any Restricted Investment (all such payments and other
     actions set forth in clauses (i) through (iv) above being collectively
     referred to as "Restricted Payments"), unless, at the time of such
     Restricted Payment:
 
             (a) no Default or Event of Default has occurred and is continuing
        or would occur as a consequence thereof;
 
             (b) after giving effect to such Restricted Payment on a pro forma
        basis as if such Restricted Payment had been made at the beginning of
        the applicable four-quarter period, the Company could incur at least
        $1.00 of additional Indebtedness pursuant to the Consolidated Cash Flow
        Leverage Ratio test described under the subheading "Incurrence of
        Indebtedness and Issuance of Disqualified Stock;" and
 
             (c) such Restricted Payment, together with the aggregate of all
        other Restricted Payments made by the Company and its Subsidiaries after
        the Issue Date (including any Restricted Payments made pursuant to
        clauses (i), (v) and (vi) of the next paragraph), is less than the sum
        of
 
                (w) 50% of the Consolidated Net Income of the Company for the
           period (taken as one accounting period) from June 30, 1996 to the end
           of the Company's most recently ended fiscal quarter for which
           internal financial statements are available at the time of such
           Restricted Payment (or, if such Consolidated Net Income for such
           period is a deficit, less 100% of such deficit), plus
 
                (x) 100% of the aggregate net cash proceeds received by the
           Company from the issue or sale of Equity Interests of the Company or
           of debt securities or Disqualified Stock of the Company that have
           been converted into such Equity Interests (other than Equity
           Interests (or convertible debt securities) sold to a Subsidiary of
           the Company and other than Disqualified Stock or debt securities that
           have been converted into Disqualified Stock) after June 30, 1996
           (other than any such Equity Interests, the proceeds of which were
           used as set forth in clauses (ii) and (viii) below) plus
 
                (y) 100% of the sum of, without duplication, (1) aggregate
           dividends or distributions received by the Company or any Subsidiary
           from any Joint Venture (other than dividends or distributions to pay
           any obligations of such Joint Venture to Persons other than the
           Company or any Subsidiary, such as income taxes), with non-cash
           distributions to be valued at the lower of book value or fair market
           value as determined by the Board of Directors, (2) the amount of the
           principal and interest payments received since the Issue Date by the
           Company or any Subsidiary from any Joint Venture and (3) the net
           proceeds from the sale of an Investment in a Joint Venture received
           by the Company or any Subsidiary; provided that there is no
           obligation to return any such amounts to the Joint Venture, and
           excluding any such dividend, distribution, interest payment or net
           proceeds that constitutes a return of capital invested pursuant to
           clause (vi) of the next succeeding paragraph, plus
 
                (z) $10.0 million.
 
     The foregoing provisions will not prohibit:
 
          (i) the payment of any dividend within 60 days after the date of
     declaration thereof, if at such date of declaration such payment would have
     complied with the provisions of the Senior Subordinated Note Indenture;
 
          (ii) the Retirement of (A) any Equity Interests of the Company or any
     Subsidiary of the Company, (B) Indebtedness of the Company that is

     substantially concurrent sale (other than to a Subsidiary of the Company)
     of, Equity Interests of the Company (other than Disqualified Stock);
 
                                       65
<PAGE>   68
 
          (iii) the Retirement of any Indebtedness of the Company subordinated
     in right of payment to the Senior Subordinated Notes in exchange for, or
     out of the proceeds of the substantially concurrent Incurrence of
     Indebtedness of the Company (other than Indebtedness to a Subsidiary of the
     Company), but only to the extent that such new Indebtedness is permitted
     under the covenant described below under the subheading "Incurrence of
     Indebtedness and Issuance of Disqualified Stock" and (A) is subordinated in
     right of payment to the Senior Subordinated Notes at least to the same
     extent as, (B) has a Weighted Average Life to Maturity at least as long as,
     and (C) has no scheduled principal payments due in any amount earlier than,
     any equivalent amount of principal under the Indebtedness so Retired;
 
          (iv) the Retirement of any Indebtedness of a Subsidiary of the Company
     in exchange for, or out of the proceeds of the substantially concurrent
     incurrence of Indebtedness of the Company or any Subsidiary but only to the
     extent that such incurrence is permitted under the covenant described below
     under the subheading "Incurrence of Indebtedness and Issuance of
     Disqualified Stock" and only to the extent that such Indebtedness (A) is
     not secured by any assets of the Company or any Subsidiary to a greater
     extent than the Retired Indebtedness was so secured, (B) has a Weighted
     Average Life to Maturity at least as long as the Retired Indebtedness and
     (C) if such Retired Indebtedness was an obligation of the Company, is pari
     passu or subordinated in right of payment to the Senior Subordinated Notes
     at least to the same extent as the Retired Indebtedness;
 
          (v) the Retirement of any Equity Interests of the Company or any
     Subsidiary of the Company held by any member of the Company's (or any of
     its Subsidiaries') management pursuant to any management equity

     aggregate price paid for all such repurchased, redeemed, acquired or
     retired Equity Interests shall not exceed $5.0 million in any twelve-month
     period plus the aggregate cash proceeds received by the Company during such
     twelve-month period from any reissuance of Equity Interests by the Company
     to members of management of the Company and its Subsidiaries;
 
          (vi) Investments in any Joint Venture; provided that at the time any
     such Investment is made, such Investment will not cause the aggregate
     amount of Investments at any one time outstanding under this clause (vi) to
     exceed the greater of (A) $25.0 million and (B) 5% of the Total Common
     Equity of the Company;
 
          (vii) the payment of cash in lieu of fractional shares (A) payable as
     dividends on Equity Interests of the Company or (B) issuable upon
     conversion of or in exchange for securities convertible into or
     exchangeable for Equity Interests of the Company or (C) issuable as a
     result of a corporate reorganization, provided that, in the case of (A) and
     (B), the issuance of such Equity Interests or securities and, in the case
     of (C), such corporate reorganization, is permitted under the terms of the
     Senior Subordinated Note Indenture; and
 
          (viii) Investments with the net cash proceeds received by the Company
     from the issue or sale of Equity Interests of the Company (other than
     Disqualified Stock) after December 31, 1997;
 
          provided, however, that at the time of, and after giving effect to,
     any Restricted Payment permitted under clauses (i), (ii), (iii), (iv), (v),
     (vi) and (viii) no Default or Event of Default shall have occurred and be
     continuing.
 
     A Permitted Investment that ceases to be a Permitted Investment pursuant to
the definition of that term, shall become a Restricted Investment, deemed to
have been made on the date that it ceases to be a Permitted Investment.
 
     The Board of Directors may designate any Subsidiary to be an Unrestricted
Subsidiary if such designation would not cause a Default or an Event of Default.
For purposes of making such determination, all outstanding Investments by the
Company and its Subsidiaries (except to the extent repaid in cash) in such
Subsidiary so designated will be deemed to be Restricted Payments at the time of
such designation and will reduce the amount available for Restricted Payments
under the first paragraph of this covenant. All such outstanding Investments
will be deemed to constitute Investments in an amount equal to the greatest of
(x) the net book value of such Investments at the time of such designation, (y)
the fair market value of such
                                       66
<PAGE>   69
 
Investments at the time of such designation and (z) the original fair market
value of such Investments at the time they were made. Such designation will only
be permitted if such Restricted Payment would be permitted at such time.
 
     The Board of Directors of the Company may at any time designate any
Unrestricted Subsidiary to be a Subsidiary; provided that such designation shall
be deemed to be an incurrence of Indebtedness by a Subsidiary of the Company of
any outstanding Indebtedness of such Unrestricted Subsidiary and such
designation shall only be permitted if (i) such Indebtedness is permitted under
the covenant described under the subheading "Incurrence of Indebtedness and
Issuance of Disqualified Stock," and (ii) no Default or Event of Default would
be in existence following such designation.
 
     Not later than the date of making any Restricted Payment, the Company shall
deliver to the Trustee an Officers' Certificate stating that such Restricted
Payment is permitted and setting forth the basis upon which the calculations
required by the covenant described under the subheading "Restricted Payments"
were computed, which calculations may be based upon the Company's latest
available financial statements.
 
     Incurrence of Indebtedness and Issuance of Disqualified Stock
 
     The Company and its Subsidiaries may not, directly or indirectly, create,
incur, issue, assume, guarantee or otherwise become directly or indirectly
liable for the payment of (collectively, "incur" and, correlatively, "incurred"
and "incurrence") any Indebtedness (including, without limitation, Acquired
Debt) and may not issue any Disqualified Stock, provided, however, that the
Company and/or any of its Subsidiaries may incur Indebtedness (including,
without limitation, Acquired Debt) or issue shares of Disqualified Stock if,
after giving effect to the incurrence of such Indebtedness or the issuance of
such Disqualified Stock, the Consolidated Cash Flow Leverage Ratio for the
Company's most recently ended four full fiscal quarters for which internal
financial statements are available immediately preceding the date of such
incurrence or issuance:
 
          (A) does not exceed 5.5 to 1 if such incurrence or issuance occurs on
     or prior to June 1, 1999; and
 
          (B) does not exceed 5.0 to 1 if such incurrence or issuance occurs
     after June 1, 1999, in each case, determined on a pro forma basis
     (including a pro forma application of the net proceeds therefrom), as if
     the additional Indebtedness had been incurred, or the Disqualified Stock
     had been issued, as the case may be, at the beginning of such four-quarter
     period.
 
     If the Company incurs any Indebtedness or issues or redeems any Preferred
Stock subsequent to the commencement of the period for which such ratio is being
calculated but prior to the event for which the calculation of the ratio is
made, then the ratio will be calculated giving pro forma effect to any such
incurrence of Indebtedness, or such issuance or redemption of Preferred Stock,
as if the same had occurred at the beginning of the applicable period. In making
such calculation on a pro forma basis, interest attributable to Indebtedness
bearing a floating interest rate shall be computed as if the rate in effect on
the date of computation had been the applicable rate for the entire period.
 
     The foregoing limitation will not apply to (with each exception to be given
independent effect):
 
          (a) the incurrence by the Company and/or any of its Subsidiaries of
     Indebtedness under a Credit Facility in an aggregate principal amount at
     any one time outstanding (with letters of credit being deemed to have a
     principal amount equal to the maximum potential liability of the Company
     and/or any of its Subsidiaries thereunder) not to exceed $150.0 million in
     the aggregate at any one time outstanding, less the aggregate amount of all
     Net Proceeds of Asset Sales applied to permanently reduce the commitments
     with respect to such Indebtedness pursuant to the covenant described above
     under the subheading "Asset Sales;"
 
          (b) the incurrence by the Company and/or any of its Subsidiaries of
     Vendor Indebtedness, provided that the aggregate amount of such Vendor
     Indebtedness incurred does not exceed 80% of the total cost of the
     Telecommunications Related Assets financed therewith (or 100% of the total
     cost of the Telecommunications Related Assets financed therewith if such
     Vendor Indebtedness was extended for the purchase of tangible physical
     assets and was so financed by the vendor thereof or an affiliate of such
     vendor);
                                       67
<PAGE>   70
 
          (c) the incurrence by the Company and/or any of its Subsidiaries of
     the Existing Indebtedness, including the Existing Senior Notes;
 
          (d) the incurrence by the Company and/or any of its Subsidiaries of
     Indebtedness in an aggregate amount not to exceed $50.0 million at any one
     time outstanding;
 
          (e) the incurrence by the Company of Indebtedness, but only to the
     extent that such Indebtedness has a final maturity no earlier than, and a
     Weighted Average Life to Maturity equal to or greater than, the final
     maturity and Weighted Average Life to Maturity, respectively, of the Senior
     Subordinated Notes, in an aggregate principal amount not to exceed 2.0
     times the net cash proceeds received by the Company after June 30, 1996
     from the issuance and sale of Equity Interests of the Company (that are not
     Disqualified Stock) plus the fair market value of Equity Interests (other
     than Disqualified Stock) issued after June 30, 1996 in connection with any
     acquisition of any Telecommunications Business;
 
          (f) the incurrence (a "Permitted Refinancing") by the Company and/or
     any of its Subsidiaries of Indebtedness issued in exchange for, or the
     proceeds of which are used to refinance, replace, refund or defease
     ("Refinance" and correlatively, "Refinanced" and "Refinancing")
     Indebtedness, other than Indebtedness incurred pursuant to clause (a)
     above, but only to the extent that:
 
             (1) the net proceeds of such Refinancing Indebtedness do not exceed
        the principal amount of and premium, if any, and accrued interest on the
        Indebtedness so Refinanced (or if such Indebtedness was issued at an
        original issue discount, the original issue price plus amortization of
        the original issue discount at the time of the repayment of such
        Indebtedness) plus the fees, expenses and costs of such Refinancing and
        reasonable prepayment premiums, if any, in connection therewith;
 
             (2) the Refinancing Indebtedness shall have a final maturity no
        earlier than, and a Weighted Average Life to Maturity equal to or
        greater than, the final maturity and Weighted Average Life to Maturity
        of the Indebtedness being Refinanced; and
 
             (3) if the Indebtedness being Refinanced is subordinated in right
        of payment to the Senior Subordinated Notes, the Refinancing
        Indebtedness shall be subordinated in right of payment to the Senior
        Subordinated Notes on terms at least as favorable to the holders of
        Senior Subordinated Notes as those contained in the documentation
        governing the Indebtedness being so Refinanced;
 
          (g) the incurrence by the Company or any of its Subsidiaries of
     intercompany Indebtedness between or among the Company and any of its
     Subsidiaries;
 
          (h) the incurrence by the Company or any of its Subsidiaries of
     Hedging Obligations that are incurred for the purpose of fixing or hedging
     interest rate or foreign currency risk with respect to any floating rate
     Indebtedness that is permitted by the terms of the Senior Subordinated Note
     Indenture to be outstanding; and
 
          (i) the incurrence by the Company of Indebtedness represented by the
     Senior Subordinated Notes and the Senior Notes, in each case, issued on the
     Issue Date.
 
     For purposes of determining compliance with this covenant, in the event
that an item of Indebtedness or Disqualified Stock meets the criteria of more
than one of the categories described in clauses (a) through (i) above or is
entitled to be incurred pursuant to the first paragraph of this covenant, the
Company shall, in its sole discretion, classify such item in any manner that
complies with this covenant and such item will be treated as having been
incurred pursuant to only one of such clauses or pursuant to the first paragraph
herein. Accrual of interest or dividends, the accretion of accreted value or
liquidation preference and the payment of interest or dividends in the form of
additional Indebtedness, Common Stock or Preferred Stock will not be deemed to
be an incurrence of Indebtedness for purposes of this covenant.

     No Senior Subordinated Debt
 
     The Company will not incur, create, issue, assume, guarantee or otherwise
become liable for any Indebtedness that is subordinate or junior in right of
payment to any Senior Debt of the Company and senior in any respect in right of
payment to the Senior Subordinated Notes.
 
     Asset Sales
 
     The Company and its Subsidiaries may not, whether in a single transaction
or a series of related transactions occurring within any twelve-month period:
 
          (i) sell, lease, convey, dispose or otherwise transfer any assets

     leases, conveyances, dispositions or other transfers:
 
             (A) in the ordinary course of business;
 
             (B) to the Company by any Subsidiary of the Company or from the

        distribution permitted under the covenant described above under the
        subheading "Restricted Payments;" or
 
             (D) that constitute the disposition of all or substantially all of
        the assets of the Company pursuant to the covenant described below under
        the subheading "Merger, Consolidation or Sale of Assets;" or
 
          (ii) issue or sell Equity Interests in any of its Subsidiaries other
     than an issuance or sale of Equity Interests of any such Subsidiary to the
     Company or a Subsidiary of the Company;
 
          if, in the case of either (i) or (ii) above, in a single transaction
     or a series of related transactions occurring within any twelve-month
     period, such assets or securities:
 
             (x) have a Fair Market Value in excess of $2.0 million; or
 
             (y) are sold or otherwise disposed of for net proceeds in excess of
        $2.0 million (each of the foregoing, an "Asset Sale"), unless:
 
                (a) no Default or Event of Default exists or would occur as a
           result thereof;
 
                (b) the Company, or such Subsidiary, as the case may be,
           receives consideration at the time of such Asset Sale at least equal
           to the Fair Market Value (evidenced by a resolution of the Board of
           Directors of the Company set forth in an Officers' Certificate
           delivered to the Trustee), of the assets or securities issued or sold
           or otherwise disposed of; and
 
                (c) except with respect to an Asset Sale constituting the
           issuance or sale of Equity Interests in the Web Hosting Subsidiary,
           at least 75% of the consideration therefor received by the Company or
           such Subsidiary is in the form of cash, provided, however, that:
 
                    (A) the amount of:
 
                        (x) any liabilities (as shown on the Company's or such
                   Subsidiary's most recent balance sheet or in the notes
                   thereto), of the Company or any Subsidiary of the Company
                   (other than liabilities that are by their terms subordinated
                   to the Senior Subordinated Notes) that are assumed by the
                   transferee of any such assets; and
 
                        (y) any notes, obligations or other securities received
                   by the Company or any such Subsidiary from such transferee
                   that are immediately converted by the Company or such
                   Subsidiary into cash,
 
                   shall be deemed to be cash (to the extent of the cash
                   received in the case of subclause (y)) for purposes of this
                   clause (c); and
 
                                       69
<PAGE>   72
 
                    (B) an amount equal to the Fair Market Value (determined as
               set forth in clause (b) above) of (1) Telecommunications Related
               Assets received by the Company or any such Subsidiary from the
               transferee that will be used by the Company or any such
               Subsidiary in the operation of a Telecommunications Business in
               the United States and (2) the Voting Stock of any Person engaged
               in the Telecommunications Business in the United States received
               by the Company or any such Subsidiary (provided that such Voting
               Stock is converted to cash within 270 days or such Person
               concurrently becomes or is a Subsidiary of the Company) will be
               deemed to be cash for purposes of this clause (c).
 
     The foregoing provisions will not apply to a sale, lease, conveyance or
other disposition of all or substantially all of the assets of the Company,
which will be governed by the provisions of the Senior Subordinated Note
Indenture described below under the subheading "Merger, Consolidation or Sale of
Assets."
 
     Within 360 days after the receipt of net proceeds of any Asset Sale, the
Company (or such Subsidiary, as the case may be) may apply the Net Proceeds from
such Asset Sale, at its option, to:
 
          (i) repay Senior Debt or permanently reduce the amounts permitted to
     be borrowed by the Company under the terms of any of its Senior Debt; or
 
          (ii) the purchase of Telecommunications Related Assets or Voting Stock
     of any Person engaged in the Telecommunications Business in the United
     States (provided that such Person concurrently becomes a Subsidiary of the
     Company); or
 
          (iii) in the case of net cash proceeds realized upon the issuance or
     sale of Equity Interests in the Web Hosting Subsidiary, fund cash operating
     losses, provide working capital and for general corporate purposes.
 
     Any Net Proceeds from any Asset Sales that are not so applied or invested
will constitute "Excess Proceeds." When the aggregate amount of Excess Proceeds
exceeds $10.0 million, the Company will be required to make an Excess Proceeds
Offer in accordance with the terms set forth under the subheading "Offer to
Purchase with Excess Asset Sale Proceeds."
 
     Liens
 
     The Company and its Subsidiaries may not, directly or indirectly, create,
incur, assume or suffer to exist any Lien securing Indebtedness or trade
payables on any asset now owned or hereafter acquired, or any income or profits
therefrom or assign or convey any right to receive income therefrom, except for
Permitted Liens.
 
     Dividend and Other Payment Restrictions Affecting Subsidiaries
 
     The Company and its Subsidiaries may not, directly or indirectly, create or
otherwise cause to become effective any consensual encumbrance or restriction on
the ability of any Subsidiary to:
 
          (i) pay dividends or make any other distributions to the Company or
     any of its Subsidiaries on its Capital Stock or with respect to any other
     interest or participation in, or measured by, its profits, or pay any
     Indebtedness owed to the Company or any of its Subsidiaries;
 
          (ii) make loans or advances to the Company or any of its Subsidiaries;
     or
 
          (iii) transfer any of its properties or assets to the Company or any
     of its Subsidiaries; except for such encumbrances or restrictions existing
     as of the Issue Date or under or by reason of:
 
             (a) Existing Indebtedness;
 
             (b) applicable law;
 
             (c) any instrument governing Acquired Debt as in effect at the time
        of acquisition (except to the extent such Indebtedness was incurred in
        connection with, or in contemplation of, such
                                       70

        acquisition), which encumbrance or restriction is not applicable to any
        Person, or the properties or assets of any Person, other than the
        Person, or the property or assets of the Person, so acquired;
 
             (d) by reason of customary non-assignment provisions in leases
        entered into in the ordinary course of business and consistent with past
        practices;
 
             (e) Indebtedness in respect of a Permitted Refinancing, provided
        that the restrictions contained in the agreements governing such
        Refinancing Indebtedness are not materially more restrictive than those
        contained in the agreements governing the Indebtedness being refinanced;
 
             (f) with respect to clause (iii) above, purchase money obligations
        for property acquired in the ordinary course of business, Vendor
        Indebtedness incurred in connection with the purchase or lease of
        Telecommunications Related Assets or performance bonds or similar
        security for performance which liens securing such obligations do not
        cover any asset other than the asset acquired or, in the case of
        performance bonds or similar security for performance, the assets
        associated with the Company's performance;
 
             (g) Indebtedness incurred under clause (a) of the covenant
        described under the subheading "Incurrence of Indebtedness and Issuance
        of Disqualified Stock;"
 
             (h) the Senior Subordinated Note Indenture and the Senior
        Subordinated Notes or future Indebtedness with substantially similar
        restrictions, if any, to the Senior Subordinated Notes;
 
             (i) the Senior Note Indenture and the Senior Notes or future
        Indebtedness with substantially similar restrictions, if any, to the
        Senior Notes; or
 
             (j) in the case of clauses (a), (c), (e), (g), (h) and (i) above,
        any amendments, modifications, restatements, renewals, increases,
        supplements, refundings, replacements or refinancings thereof, provided
        that such amendments, modifications, restatements, renewals, increases,
        supplements, refundings, replacements or refinancings are not materially
        more restrictive with respect to such dividend and other payment
        restrictions than those contained in such instruments as in effect on
        the date of their incurrence or, if later, the Issue Date.
 
     Merger, Consolidation or Sale of Assets
 
     The Company may not consolidate or merge with or into (whether or not the
Company is the surviving entity), or sell, assign, transfer, lease, convey or
otherwise dispose of all or substantially all of its properties or assets in one
or more related transactions to, another corporation, Person or entity unless:
 
          (i) the Company is the surviving entity or the entity or Person formed
     by or surviving any such consolidation or merger (if other than the
     Company) or to which such sale, assignment, transfer, lease, conveyance or
     other disposition has been made is a corporation organized or existing
     under the laws of the United States, any state thereof or the District of
     Columbia;
 
          (ii) the entity or Person formed by or surviving any such
     consolidation or merger (if other than the Company) or the entity or Person
     to which such sale, assignment, transfer, lease, conveyance or other
     disposition has been made assumes all the obligations of the Company under
     the Senior Subordinated Notes and the Senior Subordinated Note Indenture
     pursuant to a supplemental indenture in form reasonably satisfactory to the
     Trustee;
 
          (iii) immediately after such transaction no Default or Event of
     Default exists;
 
          (iv) except in connection with a Merger with or into a wholly owned
     Subsidiary of the Company, the Company, or any entity or Person formed by
     or surviving any such consolidation or merger, or to which such sale,
     assignment, transfer, lease, conveyance or other disposition has been made,
     at the time of such transaction after giving pro forma effect thereto as if
     such transaction had occurred at the beginning of the applicable fiscal
     quarter (including any Indebtedness incurred or anticipated to be incurred
     in connection with or in respect of such transaction or series of
     transactions), either (A) could incur at least $1.00 of additional
     Indebtedness pursuant to the Consolidated Cash Flow Leverage Ratio
                                       71

     test described under the subheading "Incurrence of Indebtedness and
     Issuance of Disqualified Stock" or (B) would have (x) Total Market
     Capitalization of at least $1.0 billion and (y) total Indebtedness (net of
     cash and cash equivalents that are not restricted cash or restricted cash
     equivalents as reflected on the Company's consolidated balance sheet as of
     the time of such event) in an amount no greater than 40% of its Total
     Market Capitalization; and
 
          (v) such transaction would not result in the loss, material impairment
     or adverse modification or amendment of any authorization or license of the
     Company or its Subsidiaries that would have a material adverse effect on
     the business or operations of the Company and its Subsidiaries taken as a
     whole.
 
     Transactions with Affiliates
 
     The Company and its Subsidiaries may not sell, lease, transfer or otherwise
dispose of any of their respective properties or assets to, or purchase any
property or assets from, or enter into any contract, agreement, understanding,
loan, advance or guarantee with, or for the benefit of, any Affiliate (each of
the foregoing, an "Affiliate Transaction"), unless:
 
          (i) such Affiliate Transaction is on terms that are no less favorable
     to the Company or the relevant Subsidiary than those that would have been
     obtained in a comparable transaction by the Company or such Subsidiary with
     an unrelated Person;
 
          (ii) such Affiliate Transaction is approved by a majority of the
     disinterested directors on the Board of Directors of the Company; and
 
          (iii) the Company delivers to the Trustee, with respect to any
     Affiliate Transaction involving aggregate payments in excess of $1.0
     million, a resolution of a committee of independent directors of the
     Company set forth in an Officers' Certificate certifying that such
     Affiliate Transaction complies with clauses (i) and (ii) above;
 
          provided that:
 
             (a) transactions pursuant to any employment, stock option or stock
        purchase agreement entered into by the Company or any of its
        Subsidiaries, or any grant of stock, in the ordinary course of business
        that are approved by the Board of Directors of the Company;
 
             (b) transactions between or among the Company and its Subsidiaries;
 
             (c) transactions permitted by the provisions of the Senior
        Subordinated Note Indenture described above under the subheading
        "Restricted Payments;" and
 
             (d) loans and advances to employees and officers of the Company or
        any of its Subsidiaries in the ordinary course of business in an
        aggregate principal amount not to exceed $1.0 million at any one time
        outstanding, shall not be deemed Affiliate Transactions.
 
     Business Activities
 
     The Company and its Subsidiaries may not, directly or indirectly, engage in
any business other than the Telecommunications Business.
 
     Limitations on Sale and Leaseback Transactions
 
     The Company and its Subsidiaries may not, directly or indirectly, enter
into, assume, Guarantee or otherwise become liable with respect to any Sale and
Leaseback Transaction, provided that the Company or any Subsidiary of the
Company may enter into any such transaction if:
 
          (i) the Company or such Subsidiary would be permitted under the
     covenants described above under the subheadings "Incurrence of Indebtedness
     and Issuance of Disqualified Stock" and "Liens" to incur secured
     Indebtedness in an amount equal to the Attributable Debt with respect to
     such transaction;
 
                                       72
<PAGE>   75
 
          (ii) the consideration received by the Company or such Subsidiary from
     such transaction is at least equal to the Fair Market Value of the property
     being transferred; and
 
          (iii) the Net Proceeds received by the Company or such Subsidiary from
     such transaction are applied in accordance with the covenant described
     above under the subheading "Asset Sales."
 
     Reports
 
     The Company will file with the Trustee within 15 days after it files them
with the Commission copies of the annual and quarterly reports and the
information, documents, and other reports that the Company is required to file
with the Commission pursuant to Section 13(a) or 15(d) of the Exchange Act ("SEC
Reports"). In the event the Company is not required or shall cease to be
required to file SEC Reports, pursuant to the Exchange Act, the Company will
nevertheless continue to file such reports with the Commission (unless the
Commission will not accept such a filing) and the Trustee. Whether or not
required by the Exchange Act to file SEC Reports with the Commission, so long as
any Senior Subordinated Notes are outstanding, the Company will furnish copies
of the SEC Reports to the holders of Senior Subordinated Notes at the time the
Company is required to file the same with the Trustee and make such information
available to investors who request it in writing. In addition, the Company has
agreed that, for so long as any Senior Subordinated Notes remain outstanding, it
will furnish to the holders and to securities analysts and prospective
investors, upon their request, the information required to be delivered pursuant
to Rule 144A(d)(4) under the Securities Act.
 
     Payments for Consents
 
     Neither the Company nor any of its Affiliates shall, directly or
indirectly, pay or cause to be paid any consideration, whether by way of
interest, fee or otherwise, to any holder of any Senior Subordinated Notes for
or as an inducement to any consent, waiver or amendment of any of the terms or
provisions of the Senior Subordinated Note Indenture or the Senior Subordinated
Notes unless such consideration is offered to be paid or agreed to be paid to
all holders of the Senior Subordinated Notes that consent, waive or agree to
amend in the time frame set forth in the solicitation documents relating to such
consent, waiver or agreement.
 
EVENTS OF DEFAULT AND REMEDIES
 
     Each of the following constitutes an Event of Default:
 
          (i) default for 30 days in the payment when due of interest or
     Liquidated Damages, if any, on the Senior Subordinated Notes, whether or
     not prohibited by the subordination provisions of the Senior Subordinated
     Note Indenture;
 
          (ii) default in payment when due of principal or premium, if any, on
     the Senior Subordinated Notes at maturity, upon redemption or otherwise,
     whether or not prohibited by the subordination provisions of the Senior
     Subordinated Note Indenture;
 
          (iii) failure by the Company to perform or comply with the provisions
     of the covenants described above under the subheadings "Offer to Purchase
     Upon Change of Control," "Asset Sales," "Restricted Payments," "Incurrence
     of Indebtedness and Issuance of Disqualified Stock" or "Merger,
     Consolidation or Sale of Assets;"
 
          (iv) failure by the Company for 30 days after notice from the Trustee
     or the holders of at least 25% in principal amount of the Senior
     Subordinated Notes then outstanding to comply with its other agreements in
     the Senior Subordinated Note Indenture or the Senior Subordinated Notes;
 
          (v) default under any mortgage, indenture or instrument under which
     there may be issued or by which there may be secured or evidenced any
     Indebtedness for money borrowed by the Company or any of its Subsidiaries
     (or the payment of which is guaranteed by the Company or any of its
     Subsidiaries), whether such Indebtedness or Guarantee now exists, or is
     created after the Issue Date, which default results in the acceleration
     (which acceleration has not been rescinded) of such Indebtedness prior to
     its
 
                                       73
<PAGE>   76
 
     express maturity and the principal amount of any such Indebtedness,
     together with the principal amount of any other such Indebtedness the
     maturity of which has been so accelerated, aggregates $5.0 million or more;
 
          (vi) failure by the Company or any of its Significant Subsidiaries to
     pay final judgments (other than any judgment as to which a reputable
     insurance company has accepted full liability in writing) aggregating in
     excess of $5.0 million which judgments are not paid, discharged or stayed
     within 45 days after their entry; and
 
          (vii) certain events of bankruptcy or insolvency with respect to the
     Company or any of its Significant Subsidiaries.
 
     If any Event of Default occurs and is continuing under the Senior
Subordinated Note Indenture, the Trustee or the holders of at least 25% in
principal amount of the then outstanding Senior Subordinated Notes may declare
all the Senior Subordinated Notes to be due and payable immediately. Upon such
declaration, the principal of (or, if prior to March 1, 2004, the Accreted Value
of), premium, if any, and accrued and unpaid interest and Liquidated Damages, if
any, on the Senior Subordinated Notes shall be due and payable immediately.
Notwithstanding the foregoing, in the case of an Event of Default arising from
certain events of bankruptcy or insolvency with respect to the Company or any of
its Significant Subsidiaries, the foregoing amount shall ipso facto become due
and payable without further action or notice. No premium is payable upon
acceleration of the Senior Subordinated Notes except that in the case of an
Event of Default that is the result of an action or inaction by the Company or
any of its Subsidiaries intended to avoid restrictions on or premiums related to
redemptions of the Senior Subordinated Notes contained in the Senior
Subordinated Note Indenture or the Senior Subordinated Notes. The amount
declared due and payable will include the premium that would have been
applicable on a voluntary prepayment of the Senior Subordinated Notes. Holders
of the Senior Subordinated Notes may not enforce the Senior Subordinated Note
Indenture or the Senior Subordinated Notes except as provided in the Senior
Subordinated Note Indenture. Subject to certain limitations, holders of a
majority in principal amount of the then outstanding Senior Subordinated Notes
may direct the Trustee in its exercise of any trust or power. The Trustee may
withhold from holders of the Senior Subordinated Notes notice of any continuing
Default or Event of Default (except a Default or Event of Default relating to
the payments of principal or interest) if it determines that withholding notice
is in such holders' interest.
 
     The holders of a majority in aggregate principal amount of the Senior
Subordinated Notes then outstanding, by notice to the Trustee, may on behalf of
the holders of all of the Senior Subordinated Notes, waive any existing Default
or Event of Default and its consequences under the Senior Subordinated Note
Indenture, except a continuing Default or Event of Default in the payment of
interest or Liquidated Damages or premium on, or the principal of, the Senior
Subordinated Notes.
 
     The Company is required to deliver to the Trustee annually a statement
regarding compliance with the Senior Subordinated Note Indenture, and the
Company is required upon becoming aware of any Default or Event of Default to
deliver to the Trustee a statement specifying such Default or Event of Default.
 
NO PERSONAL LIABILITY OF DIRECTORS, OFFICERS, EMPLOYEES AND STOCKHOLDERS
 
     No director, officer, employee, incorporator or stockholder of the Company,
as such, shall have any liability for any obligations of the Company under the
Senior Subordinated Notes or the Senior Subordinated Note Indenture or for any
claim based on, in respect of, or by reason of such obligations or their
creation. Each holder of Senior Subordinated Notes by accepting a Senior
Subordinated Note waives and releases all such liability. The waiver and release
are part of the consideration for issuance of the Senior Subordinated Notes.
Such waiver may not be effective to waive liabilities under the federal
securities laws and it is the view of the Commission that such a waiver is
against public policy.

LEGAL DEFEASANCE AND COVENANT DEFEASANCE
 
     The Company may, at its option and at any time, elect to have its
obligations discharged with respect to the outstanding Senior Subordinated Notes
("Legal Defeasance"). Such Legal Defeasance means that the Company shall be
deemed to have paid and discharged the entire indebtedness represented by the
outstanding Senior Subordinated Notes, except for:
 
          (a) the rights of holders of outstanding Senior Subordinated Notes to
     receive from the trust described below payments in respect of the principal
     of, premium, if any, and interest on and Liquidated Damages with respect to
     such Senior Subordinated Notes when such payments are due, or on the
     redemption date, as the case may be;
 
          (b) the Company's obligations with respect to the Senior Subordinated
     Notes concerning issuing temporary Senior Subordinated Notes, registration
     of Senior Subordinated Notes, mutilated, destroyed, lost or stolen Senior
     Subordinated Notes and the maintenance of an office or agency for payment
     and money for security payments held in trust;
 
          (c) the rights, powers, trust, duties and immunities of the Trustee,
     and the Company's obligations in connection therewith; and
 
          (d) the Legal Defeasance provisions of the Senior Subordinated Note
     Indenture.
 
          In addition, the Company may, at its option and at any time, elect to
     have the obligations of the Company released with respect to certain
     covenants that are described in the Senior Subordinated Note Indenture
     ("Covenant Defeasance") and thereafter any omission to comply with such
     obligations shall not constitute a Default or Event of Default with respect
     to the Senior Subordinated Notes. In the event Covenant Defeasance occurs,
     certain events (not including non payment, bankruptcy, receivership,
     rehabilitation and insolvency events) described under the subheading
     "Events of Default" will no longer constitute an Event of Default with
     respect to the Senior Subordinated Notes.
 
     In order to exercise either Legal Defeasance or Covenant Defeasance:
 
          (i) the Company must irrevocably deposit with the Trustee, in trust,
     for the benefit of the holders of the Senior Subordinated Notes, cash in
     U.S. dollars, non-callable U.S. government obligations, or a combination
     thereof, in such amounts as will be sufficient, in the opinion of a
     nationally recognized firm of independent public accountants selected by
     the Company, to pay the principal of, premium and Liquidated Damages, if
     any, and interest on the outstanding Senior Subordinated Notes, on the
     stated maturity or on the applicable optional redemption date, as the case
     may be, of such principal or installment of principal of, premium, if any,
     or interest on or Liquidated Damages with respect to the outstanding Senior
     Subordinated Notes;
 
          (ii) in the case of Legal Defeasance, the Company must deliver to the
     Trustee an opinion of counsel in the United States reasonably acceptable to
     the Trustee confirming that (A) the Company has received from, or there has
     been published by, the Internal Revenue Service a ruling or (B) since the
     Issue Date, there has been a change in the applicable federal income tax
     law, in either case to the effect that, and based thereon such opinion of
     counsel shall confirm that, the holders of the outstanding Senior
     Subordinated Notes will not recognize income, gain or loss for federal
     income tax purposes as a result of such Legal Defeasance and will be
     subject to federal income tax on the same amounts, in the same manner and
     at the same times as would have been the case if such Legal Defeasance had
     not occurred;
 
          (iii) in the case of Covenant Defeasance, the Company must deliver to
     the Trustee an opinion of counsel in the United States reasonably
     acceptable to the Trustee confirming that the holders of the outstanding
     Senior Subordinated Notes will not recognize income, gain or loss for
     federal income tax purposes as a result of such Covenant Defeasance and
     will be subject to federal income tax on the same amounts, in the same
     manner and at the same times as would have been the case if such Covenant
     Defeasance had not occurred;
 
                                       75
<PAGE>   78
 
          (iv) no Default or Event of Default shall have occurred and be
     continuing on the date of such deposit (other than a Default or Event of
     Default resulting from the borrowing of funds to be applied to such
     deposit) or insofar as Events of Default from bankruptcy or insolvency
     events are concerned, at any time in the period ending on the 91st day
     after the date of deposit;
 
          (v) such Legal Defeasance or Covenant Defeasance will not result in a
     breach or violation of, or constitute a default under any material
     agreement or instrument (other than the Senior Subordinated Note Indenture)
     to which the Company or any of its Subsidiaries is a party or by which the
     Company or any of its Subsidiaries is bound;
 
          (vi) the Company must have delivered to the Trustee an opinion of
     counsel to the effect that after the 91st day (or such other applicable
     date) following the deposit, the trust funds will not be subject to the
     effect of any applicable bankruptcy, insolvency, reorganization or similar
     laws affecting creditors' rights generally;
 
          (vii) the Company must deliver to the Trustee an Officers' Certificate
     stating that the deposit was not made by the Company with the intent of
     preferring the holders of Senior Subordinated Notes over the other
     creditors of the Company with the intent of defeating, hindering, delaying
     or defrauding creditors of the Company or others; and
 
          (viii) the Company must deliver to the Trustee an Officers'
     Certificate and an opinion of counsel, each stating that all conditions
     precedent provided for relating to the Legal Defeasance or the Covenant
     Defeasance have been complied with.
 
AMENDMENT, SUPPLEMENT AND WAIVER
 
     Except as provided in the next succeeding paragraph, the Senior
Subordinated Note Indenture or the Senior Subordinated Notes may be amended or
supplemented with the consent of the holders of at least a majority in principal
amount of the Senior Subordinated Notes then outstanding (including consents
obtained in connection with a tender offer or exchange offer for Senior
Subordinated Notes), and any existing default or compliance with any provision
of the Senior Subordinated Note Indenture or the Senior Subordinated Notes may
be waived with the consent of the holders of a majority in principal amount of
the then outstanding Senior Subordinated Notes (including consents obtained in
connection with a tender offer or exchange offer for Senior Subordinated Notes).
 
     Without the consent of each holder affected, however, an amendment or
waiver may not (with respect to any Senior Subordinated Note held by a
non-consenting holder):
 
          (i) reduce the principal amount of Senior Subordinated Notes whose
     holders must consent to an amendment, supplement or waiver;
 
          (ii) reduce the principal or change the fixed maturity of any Senior
     Subordinated Note or alter the provisions with respect to the redemption of
     the Senior Subordinated Notes (other than provisions relating to the
     covenants described under the subheadings "Offer to Purchase upon Change of
     Control" and "Offer to Purchase with Excess Asset Sale Proceeds");
 
          (iii) reduce the rate of or change the time for payment of interest on
     any Senior Subordinated Notes;
 
          (iv) waive a Default or Event of Default in the payment of principal
     of or premium, if any, or interest on the Senior Subordinated Notes (except
     a rescission of acceleration of the Senior Subordinated Notes by the
     holders of at least a majority in aggregate principal amount of the Senior
     Subordinated Notes and a waiver of the payment default that resulted from
     such acceleration);
 
          (v) make any Senior Subordinated Note payable in money other than that
     stated in the Senior Subordinated Notes;
 
                                       76
<PAGE>   79
 
          (vi) make any change in the provisions of the Senior Subordinated Note
     Indenture relating to waivers of past Defaults or the rights of holders of
     Senior Subordinated Notes to receive payments of principal of, premium, if
     any, or interest on the Senior Subordinated Notes;
 
          (vii) waive a redemption payment with respect to any Senior
     Subordinated Note (other than a payment required by one of the covenants
     described above under the subheadings "Offer to Purchase upon Change of
     Control" and "Offer to Purchase with Excess Asset Sale Proceeds"); or
 
          (viii) make any change in the foregoing amendment and waiver
     provisions.
 
          In addition, any amendment to, or waiver of, the provisions of the
     Senior Subordinated Note Indenture relating to subordination that adversely
     affects the rights of the Holders of Senior Subordinated Notes will require
     the consent of the Holders of at least 75% in aggregate principal amount of
     Senior Subordinated Notes then outstanding.
 
     Notwithstanding the foregoing, without the consent of any holder of Senior
Subordinated Notes, the Company and the Trustee may amend or supplement the
Senior Subordinated Note Indenture or the Senior Subordinated Notes:
 
             (a) to cure any ambiguity, defect or inconsistency;
 
             (b) to provide for uncertificated Senior Subordinated Notes in
        addition to or in place of certificated Senior Subordinated Notes;
 
             (c) to provide for the assumption of the Company's obligations to
        holders of the Senior Subordinated Notes in the case of a merger or
        consolidation;
 
             (d) to make any change that would provide any additional rights or
        benefits to the holders of the Senior Subordinated Notes or that does
        not adversely affect the legal rights under the Senior Subordinated Note
        Indenture of any such holder; or
 
             (e) to comply with requirements of the Commission in order to
        effect or maintain the qualification of the Senior Subordinated Note
        Indenture under the Trust Indenture Act.
 
CONCERNING THE TRUSTEE
 
     If the Trustee becomes a creditor of the Company, the Senior Subordinated
Note Indenture limits its rights to obtain payment of claims in certain cases,
or to realize on certain property received in respect of any such claim as
security or otherwise. The Trustee will be permitted to engage in other
transactions with the Company; however, if the Trustee acquires any conflicting
interest, it must eliminate such conflict within 90 days, apply to the
Commission for permission to continue as Trustee or resign.
 
     The holders of a majority in principal amount of the then outstanding
Senior Subordinated Notes will have the right to direct the time, method and
place of conducting any proceeding for exercising any remedy available to the
Trustee, subject to certain exceptions. The Senior Subordinated Note Indenture
provides that in case an Event of Default shall occur and be continuing, the
Trustee will be required, in the exercise of its powers, to use the degree of
care of a prudent man in the conduct of his own affairs. Subject to such
provisions, the Trustee will be under no obligation to exercise any of its
rights or powers under the Senior Subordinated Note Indenture at the request of
any holder of Senior Subordinated Notes, unless such holder shall have offered
to the Trustee security and indemnity satisfactory to it against any loss,
liability or expense.
 
     No holder of any Senior Subordinated Note will have any right to institute
any proceeding with respect to the Senior Subordinated Note Indenture or for any
remedy thereunder, unless:
 
          (i) such holder gives to the Trustee written notice of a continuing
     Event of Default;
 
          (ii) holders of at least 25% in principal amount of the then
     outstanding Senior Subordinated Notes make a written request to pursue the
     remedy;
 
                                       77
<PAGE>   80
 
          (iii) such holders of the Senior Subordinated Notes provide to the
     Trustee satisfactory indemnity; and
 
          (iv) the Trustee does not comply within 60 days. Otherwise, no holder
     of any Senior Subordinated Note will have any right to institute any
     proceeding with respect to the Senior Subordinated Note Indenture or for
     any remedy thereunder,
 
     except:
 
          (i) a holder of a Senior Subordinated Note may institute suit for
     enforcement of payment of the principal of and premium, if any, or interest
     on such Senior Subordinated Note on or after the respective due dates
     expressed in such Senior Subordinated Note (including upon acceleration
     thereof); or
 
          (ii) the institution of any proceeding with respect to the Senior
     Subordinated Note Indenture or any remedy thereunder, including without
     limitation acceleration, by the Holders of a majority in principal amount
     of the outstanding Senior Subordinated Notes, provided that, upon
     institution of any proceeding or exercise of any remedy such Holders
     provide the Trustee with prompt notice thereof.

REGISTRATION RIGHTS; LIQUIDATED DAMAGES
 
     The following description is a summary of the material provisions of the
Senior Subordinated Note Registration Rights Agreement. It does not restate that
agreement in its entirety. We urge you to read the Senior Subordinated Note
Registration Rights Agreement in its entirety because it, and not this
description, defines your registration rights as Holders of these Senior
Subordinated Notes. See "Additional Information."
 
     Pursuant to the Senior Subordinated Note Registration Rights Agreement, the
Company agreed to file with the Commission a registration statement (the "Senior
Subordinated Exchange Offer Registration Statement") on the appropriate form
under the Securities Act with respect to an offer to exchange (the "Senior
Subordinated Exchange Offer") the 12 1/4% Senior Subordinated Notes for 12 1/4%
Series B Senior Subordinated Notes. Upon the effectiveness of the Senior
Subordinated Exchange Offer Registration Statement, the Company will offer to
the holders of Transfer Restricted Securities pursuant to the Senior
Subordinated Exchange Offer who are able to make certain representations the
opportunity to exchange their Transfer Restricted Securities for a new issue of
senior notes of the Company (the "12 1/4% Series B Senior Subordinated Notes")
registered under the Securities Act, with terms substantially identical to those
of the 12 1/4% Senior Subordinated Notes.
 
     If:
 
          (i) the Company is not:
 
             (a) required to file the Senior Subordinated Exchange Offer
        Registration Statement; or
 
             (b) permitted to consummate the Senior Subordinated Exchange Offer
        because the Senior Subordinated Exchange Offer is not permitted by
        applicable law or Commission policy; or
 
          (ii) any holder of Transfer Restricted Securities notifies the Company
     within the specified time period that:
 
             (a) it is prohibited by law or Commission policy from participating
        in the Senior Subordinated Exchange Offer,
 
             (b) it may not resell the 12 1/4% Series B Senior Subordinated
        Notes acquired by it in the Senior Subordinated Exchange Offer to the
        public without delivering a prospectus and the
 
                                       78
<PAGE>   81
 
        prospectus contained in the Senior Subordinated Exchange Offer
        Registration Statement is not appropriate or available for such resales;
        or
 
             (c) it is a broker-dealer and owns 12 1/4% Senior Subordinated
        Notes acquired directly from the Company or an affiliate of the Company,
 
          the Company will file with the Commission a shelf registration
     statement (the "Senior Subordinated Notes Shelf Registration Statement") to
     cover resales of the 12 1/4% Senior Subordinated Notes by the Holders
     thereof who satisfy certain conditions relating to the provision of
     information in connection with the Senior Subordinated Notes Shelf
     Registration Statement.
 
     The Company will use its best efforts to cause the applicable registration
statement to be declared effective as promptly as possible by the Commission.
 
     For purposes of the foregoing, "Transfer Restricted Securities" means each
12 1/4% Senior Subordinated Note until:
 
          (i) the date on which such 12 1/4% Senior Subordinated Note has been
     exchanged by a Person other than a broker-dealer for a 12 1/4% Series B
     Senior Subordinated Note in the Senior Subordinated Exchange Offer;
 
          (ii) following the exchange by a broker-dealer in the Senior
     Subordinated Exchange Offer of a 12 1/4% Senior Subordinated Note for a
     12 1/4% Series B Senior Subordinated Note, the date on which such 12 1/4%
     Series B Senior Subordinated Note is sold to a purchaser who receives from
     such broker-dealer on or prior to the date of such sale a copy of the
     prospectus contained in the Senior Subordinated Exchange Offer Registration
     Statement;
 
          (iii) the date on which such 12 1/4% Senior Subordinated Note has been
     effectively registered under the Securities Act and disposed of in
     accordance with the Senior Subordinated Notes Shelf Registration Statement;
     or
 
          (iv) the date on which such 12 1/4% Senior Subordinated Note may be
     distributed to the public pursuant to Rule 144 under the Securities Act.
 
     The Senior Subordinated Note Registration Rights Agreement will provide
that:
 
          (i) unless the Senior Subordinated Exchange Offer would not be
     permitted by applicable law or Commission policy, the Company will file a
     Senior Subordinated Exchange Offer Registration Statement with the
     Commission on or prior to 60 days after the Issue Date;
 
          (ii) unless the Senior Subordinated Exchange Offer would not be
     permitted by applicable law or Commission policy, the Company will use its
     best efforts to have the Senior Subordinated Exchange Offer Registration
     Statement declared effective by the Commission on or prior to 180 days
     after the Issue Date;
 
          (iii) unless the Senior Subordinated Exchange Offer would not be
     permitted by applicable law or Commission policy, the Company will
 
             (a) upon the effectiveness of the Senior Subordinated Exchange
        Offer Registration Statement, commence the Senior Subordinated Exchange
        Offer and
 
             (b) use its best efforts to issue on or prior to 30 business days
        after the date on which the Senior Subordinated Exchange Offer
        Registration Statement was declared effective by the Commission, 12 1/4%
        Series B Senior Subordinated Notes in exchange for all 12 1/4% Senior
        Subordinated Notes tendered prior thereto in the Senior Subordinated
        Exchange Offer; and
 
          (iv) if obligated to file the Senior Subordinated Notes Shelf
     Registration Statement, the Company will use its best efforts to file the
     Senior Subordinated Notes Shelf Registration Statement with the Commission
     on or prior to 60 days after such filing obligation arises (and, if the
     Senior Subordinated Exchange Offer is not permitted by applicable law or
     Commission policy, in any event within 150 days
 
                                       79
<PAGE>   82
 
     after the Issue Date) and to cause the Senior Subordinated Notes Shelf
     Registration Statement to be declared effective by the Commission on or
     prior to 180 days after such obligation arises (and, if the Senior
     Subordinated Exchange Offer is not permitted by applicable law or
     Commission policy, in any event within 270 days after the Issue Date).
 
     If:
 
          (a) the Company fails to file any of the registration statements
     required by the Senior Subordinated Note Registration Rights Agreement on
     or before the date specified for such filing;
 
          (b) any of such registration statements is not declared effective by
     the Commission on or prior to the date specified for such effectiveness
     (the "Senior Subordinated Note Effectiveness Target Date");
 
          (c) the Company fails to consummate the Senior Subordinated Exchange
     Offer within 30 business days of the Senior Subordinated Note Effectiveness
     Target Date with respect to the Senior Subordinated Exchange Offer
     Registration Statement; or
 
          (d) the Senior Subordinated Notes Shelf Registration Statement or the
     Senior Subordinated Exchange Offer Registration Statement is declared
     effective but thereafter ceases to be effective or usable in connection
     with resales of Transfer Restricted Securities during the periods specified
     in the Senior Subordinated Note Registration Rights Agreement, provided,
     that the Company will have the option of suspending the effectiveness of
     the Senior Subordinated Notes Shelf Registration Statement or the Senior
     Subordinated Exchange Offer Registration Statement, without becoming
     obligated to pay Liquidated Damages for periods of up to a total of 60 days
     in any calendar year if the Board of Directors of the Company determines
     that compliance with the disclosure obligations necessary to maintain the
     effectiveness of the Senior Subordinated Notes Shelf Registration Statement
     at such time could reasonably be expected to have an adverse effect on the
     Company or a pending corporate transaction (each such event referred to in
     clauses (a) through (d) above a "Senior Subordinated Note Registration
     Default"),
 
          then the Company will pay liquidated damages ("Liquidated Damages") to
     each Holder of Transfer Restricted Securities, with respect to the first
     90-day period immediately following the occurrence of such Senior
     Subordinated Note Registration Default, in an amount equal to $.05 per week
     per $1,000 principal amount of Senior Subordinated Notes constituting
     Transfer Restricted Securities held by such Holder.
 
     The amount of the Liquidated Damages will increase by an additional $.05
per week per $1,000 principal amount of Senior Subordinated Notes constituting
Transfer Restricted Securities with respect to each subsequent 90-day period
until all Senior Subordinated Note Registration Defaults have been cured, up to
a maximum amount of Liquidated Damages of $.50 per week per $1,000 principal
amount of Senior Subordinated Notes constituting Transfer Restricted Securities.
 
     All accrued Liquidated Damages will be paid by the Company on each Interest
Payment Date to the Global Senior Subordinated Note Holder by wire transfer of
immediately available funds or by federal funds check and to Holders of
Certificated Securities by mailing checks to their registered addresses.
 
     Following the cure of all Senior Subordinated Note Registration Defaults,
the accrual of Liquidated Damages will cease.
 
     Holders of Senior Subordinated Notes will be required to make certain
representations to the Company (as described in the Senior Subordinated Note
Registration Rights Agreement) in order to participate in the Senior
Subordinated Exchange Offer and will be required to deliver information to be
used in connection with the Senior Subordinated Notes Shelf Registration
Statement and to provide comments on the Senior Subordinated Notes Shelf
Registration Statement within the time periods set forth in the Senior
Subordinated Note Registration Rights Agreement in order to have their Senior
Subordinated Notes included in the Senior Subordinated Notes Shelf Registration
Statement and benefit from the provisions regarding Liquidated Damages set forth
above.

BOOK-ENTRY, DELIVERY AND FORM
 
     Except as set forth in the next paragraph, the 12 1/4% Series B Senior
Subordinated Notes to be resold as set forth herein will initially be issued in
the form of one or more global certificates (the "Global Senior Subordinated
Notes"). The Global Senior Subordinated Notes will be deposited on the Exchange
Date with, or on behalf of, The Depository Trust Company (the "Depositary") and
registered in the name of Cede & Co., as nominee of the Depositary (such nominee
being referred to herein as the "Global Holder").
 
     Senior Subordinated Notes that are issued as described below under the
subheading "Certificated Securities" will be issued in the form of registered
definitive certificates (the "Certificated Securities"). Upon the transfer of
Certificated Securities, such Certificated Securities may, unless all Global
Senior Subordinated Notes have previously been exchanged for Certificated
Securities, be exchanged for an interest in the Global Senior Subordinated Note
representing the principal amount of Senior Subordinated Notes being
transferred, subject to the transfer restrictions set forth in the Senior
Subordinated Note Indenture.
 
     The Depositary is a limited-purpose trust company that was created to hold
securities for its participating organizations (collectively, the "Participants"
or the "Depositary's Participants") and to facilitate the clearance and
settlement of transactions in such securities between Participants through
electronic book-entry changes in accounts of its Participants. The Depositary's
Participants include securities brokers and dealers (including the initial
purchasers), banks and trust companies, clearing corporations and certain other
organizations. Access to the Depositary's system is also available to other
entities such as banks, brokers, dealers and trust companies (collectively, the
"Indirect Participants" or the "Depositary's Indirect Participants") that clear
through or maintain a custodial relationship with a Participant, either directly
or indirectly. Persons who are not Participants may beneficially own securities
held by or on behalf of the Depositary only through the Depositary's
Participants or the Depositary's Indirect Participants.
 
     The Company expects that pursuant to procedures established by the
Depositary:
 
          (i) upon deposit of the Global Senior Subordinated Notes, the
     Depositary will credit the accounts of Participants designated by the
     initial purchasers with portions of the principal amount of the Global
     Senior Subordinated Notes; and
 
          (ii) ownership of the Senior Subordinated Notes evidenced by the
     Global Senior Subordinated Notes will be shown on, and the transfer of
     ownership thereof will be effected only through, records maintained by the
     Depositary (with respect to the interests of the Depositary's
     Participants), the Depositary's Participants and the Depositary's Indirect
     Participants.
 
     Prospective purchasers are advised that the laws of some states require
that certain persons take physical delivery in definitive form of securities
that they own. Consequently, the ability to transfer Senior Subordinated Notes
evidenced by the Global Senior Subordinated Note will be limited to such extent.
 
     So long as the Global Senior Subordinated Note Holder is the registered
owner of any Senior Subordinated Notes, the Global Senior Subordinated Note
Holder will be considered the sole Holder under the Senior Subordinated Note
Indenture of any Senior Subordinated Notes evidenced by the Global Senior
Subordinated Notes. Beneficial owners of Senior Subordinated Notes evidenced by
the Global Senior Subordinated Notes will not be considered the owners or
Holders thereof under the Senior Subordinated Note Indenture for any purpose,
including with respect to the giving of any directions, instructions or
approvals to the Trustee thereunder. Neither the Company nor the Trustee will
have any responsibility or liability for any aspect of the records of the
Depositary or for maintaining, supervising or reviewing any records of the
Depositary relating to the Senior Subordinated Notes.
 
     Payments in respect of the principal of, premium, if any, interest and
Liquidated Damages, if any, on any Senior Subordinated Notes registered in the
name of the Global Senior Subordinated Note Holder on the applicable record date
will be payable by the Trustee to or at the direction of the Global Senior
Subordinated Note Holder in its capacity as the registered Holder under the
Senior Subordinated Note Indenture. Under the terms of the Senior Subordinated
Note Indenture, the Company and the Trustee may treat the persons in whose names
Senior Subordinated Notes, including the Global Senior Subordinated Notes, are
registered as
 
                                       81
<PAGE>   84
 
the owners thereof for the purpose of receiving such payments. Consequently,
neither the Company nor the Trustee has or will have any responsibility or
liability for the payment of such amounts to beneficial owners of Senior
Subordinated Notes. The Company believes, however, that it is currently the
policy of the Depositary to immediately credit the accounts of the relevant
Participants with such payments, in amounts proportionate to their respective
holdings of beneficial interests in the relevant security as shown on the
records of the Depositary. Payments by the Depositary's Participants and the
Depositary's Indirect Participants to the beneficial owners of the Senior
Subordinated Notes will be governed by standing instructions and customary
practice and will be the responsibility of the Depositary's Participants or the
Depositary's Indirect Participants.
 
     Certificated Securities
 
     Subject to certain conditions, any person having a beneficial interest in a
Global Senior Subordinated Note may, upon request to the Trustee, exchange such
beneficial interest for Senior Subordinated Notes in the form of Certificated
Securities. Upon any such issuance, the Trustee is required to register such
Certificated Securities in the name of, and cause the same to be delivered to,
such person or persons (or the nominee of any thereof).
 
     In addition, if:
 
          (i) the Company notifies the Trustee in writing that the Depositary is
     no longer willing or able to act as a depositary and a successor depositary
     is not appointed by the Company within 120 days; or
 
          (ii) the Company, at its option, notifies the Trustee in writing that
     it elects to cause the issuance of Senior Subordinated Notes in the form of
     Certificated Securities under the Senior Subordinated Note Indenture,
 
     then, upon surrender by the Global Senior Subordinated Note Holder of its
Global Senior Subordinated Note, Senior Subordinated Notes in such form will be
issued to each person that the Global Senior Subordinated Note Holder and the
Depositary identify as being the beneficial owner of the related Senior
Subordinated Notes.
 
     Neither the Company nor the Trustee will be liable for any delay by the
Global Senior Subordinated Note Holder or the Depositary in identifying the
beneficial owners of Senior Subordinated Notes and the Company and the Trustee
may conclusively rely on, and will be protected in relying on, instructions from
the Global Senior Subordinated Note Holder or the Depositary for all purposes.
 
SAME DAY SETTLEMENT AND PAYMENT
 
     The Company will make payments in respect of the Senior Subordinated Notes
represented by the Global Senior Subordinated Notes (including principal,
premium, if any, interest and Liquidated Damages, if any) by wire transfer of
immediately available funds to the accounts specified by the Global Senior
Subordinated Note Holder. With respect to Senior Subordinated Notes in
certificated form, the Company will make all payments of principal, premium, if
any, interest and Liquidated Damages, if any, by wire transfer of immediately
available funds to the accounts specified by the Holders thereof or, if no such
account is specified, by mailing a check to each such Holder's registered
address. The Senior Subordinated Notes represented by the Global Senior
Subordinated Notes are expected to be eligible to trade in the Depositary's
Same-Day Funds Settlement System, and any permitted secondary market trading
activity in such Senior Subordinated Notes will, therefore, be required by the
Depositary to be settled in immediately available funds. The Company expects
that secondary trading in any certificated Senior Subordinated Notes will also
be settled in immediately available funds.

exchange on which such shares are listed or admitted to trading or, if not
listed or admitted to trading on any national securities exchange, on the Nasdaq
National Market or, if such shares are not listed or admitted to trading on any

under the Securities Act), the average of the reported closing bid and asked

     "Consolidated Cash Flow Leverage Ratio" with respect to any Person means
the ratio of the Consolidated Indebtedness of such Person to the Consolidated
EBITDA of such Person for the relevant period; provided, however, that:
 
          (1) if the Company or any Subsidiary of the Company has incurred any
     Indebtedness (including Acquired Debt) or if the Company has issued any
     Disqualified Stock or if any Subsidiary of the Company has issued any
     Preferred Stock since the beginning of such period that remains outstanding
     on the date of such determination or if the transaction giving rise to the
     need to calculate the Consolidated Cash Flow Leverage Ratio is an
     incurrence of Indebtedness (including Acquired Debt) or the issuance of
     Disqualified Stock by the Company, Consolidated EBITDA and Consolidated
     Indebtedness for such period will be calculated after giving effect on a
     pro forma basis to:
 
             (A) such Indebtedness, Disqualified Stock or Preferred Stock, as
        applicable, as if such Indebtedness had been incurred or such stock had
        been issued on the first day of such period;
 
             (B) the discharge of any other Indebtedness repaid, repurchased,
        defeased or otherwise discharged with the proceeds of such new
        Indebtedness or sale of stock as if such discharge had occurred on the
        first day of such period; and
 
             (C) the interest income realized by the Company or its Subsidiaries
        on the proceeds of such Indebtedness or of such stock sale, to the
        extent not yet applied at the date of determination, assuming such
        proceeds earned interest at the rate in effect on the date of
        determination from the first day of such period through such date of
        determination;
 
          (2) if since the beginning of such period the Company or any
     Subsidiary of the Company has made any sale of assets (including, without
     limitation, any Asset Sales or pursuant to any Sale and Leaseback
     Transaction), Consolidated EBITDA for such period will be:
 
             (A) reduced by an amount equal to Consolidated EBITDA (if positive)
        directly attributable to the assets which are the subject of such sale
        of assets for such period; or
 
                                       84
<PAGE>   87
 
             (B) increased by an amount equal to Consolidated EBITDA (if
        negative) directly attributable thereto for such period; and
 
          (3) if since the beginning of such period the Company or any
     Subsidiary of the Company (by merger or otherwise) has made an Investment
     in any Subsidiary of the Company (or any Person which becomes a Subsidiary
     of the Company) or has made an acquisition of assets, including, without
     limitation, any acquisition of assets occurring in connection with a
     transaction causing a calculation of Consolidated EBITDA to be made
     hereunder, which constitutes all or substantially all of an operating unit
     of a business, Consolidated EBITDA for such period will be calculated after
     giving pro forma effect thereto (including the incurrence of any
     Indebtedness (including Acquired Debt)) as if such Investment or
     acquisition occurred on the first day of such period.
 
          For purposes of this definition, whenever pro forma effect is to be
     given to an acquisition of assets, the pro forma calculations will be
     determined in good faith by a responsible financial or accounting Officer
     of the Company, provided, however, that such Officer shall assume:
 
             (i) the historical sales and gross profit margins associated with
        such assets for any consecutive 12-month period ended prior to the date
        of purchase (provided that the first month of such 12-month period will
        be no more than 18 months prior to such date of purchase); and
 
             (ii) other expenses as if such assets had been owned by the Company
        since the first day of such period. If any Indebtedness (including,
        without limitation, Acquired Debt) bears a floating rate of interest and
        is being given pro forma effect, the interest on such Indebtedness will
        be calculated as if the rate in effect on the date of determination had
        been the applicable rate for the entire period.
 
     "Consolidated EBITDA" as of any date of determination means the
Consolidated Net Income for such period (but without giving effect to
adjustments, accruals, deductions or entries resulting from purchase accounting
extraordinary losses or gains and any gains or losses from any Asset Sales),
plus the following to the extent deducted in calculating such Consolidated Net
Income:
 
          (i) provision for taxes based on income or profits of such Person and
     its Subsidiaries for such period;
 
          (ii) Consolidated Interest Expense;
 
          (iii) depreciation, amortization (including amortization of goodwill
     and other intangibles); and
 
          (iv) other non-cash charges (excluding any such non-cash charge to the
     extent that it represents an accrual of or reserve for cash charges in any
     future period or amortization of a prepaid cash expense that was paid in a
     prior period and excluding non-cash interest and dividend income) of such
     Person and its Subsidiaries for such period, in each case, on a
     consolidated basis and determined in accordance with GAAP.
 
     Notwithstanding the foregoing, the provision for taxes on the income or
profits of, and the depreciation, amortization, interest expense, and other
non-cash charges of, a Subsidiary of the referent Person shall be added to
Consolidated Net Income to compute Consolidated EBITDA only to the extent (and
in same proportion) that the Net Income of such Subsidiary was included in
calculating the Consolidated Net Income of such Person and only if a
corresponding amount would be permitted at the date of determination to be
dividended to the Company by such Subsidiary, or loaned to the Company by any
such Subsidiary, without prior approval (that has not been obtained), pursuant
to the terms of its charter and all agreements, instruments, judgments, decrees,
orders, statutes, rules and governmental regulations applicable to that
Subsidiary or its stockholders.
 
     "Consolidated Indebtedness" means, with respect to any Person, as of any
date of determination, the aggregate amount of Indebtedness of such Person and
its Subsidiaries as of such date calculated on a consolidated basis in
accordance with GAAP consistently applied.

aggregate of the following for such Person for such period determined on a
consolidated basis in accordance with GAAP:
 
          (a) the amount of interest in respect of Indebtedness (including
     amortization of original issue discount, amortization of debt issuance
     costs, and non-cash interest payments on any Indebtedness, the interest
     portion of any deferred payment obligation and after taking into account
     the effect of elections made under any Interest Rate Agreement however
     denominated with respect to such Indebtedness);
 
          (b) the amount of Redeemable Dividends (to the extent not already
     included in Indebtedness in determining Consolidated Interest Expense for
     the relevant period); and
 
          (c) the interest component of rentals in respect of any Capital Lease
     Obligation paid, in each case whether accrued or scheduled to be paid or
     accrued by such Person during such period to the extent such amounts were
     deducted in computing Consolidated Net Income, determined on a consolidated
     basis in accordance with GAAP. For purposes of this definition interest on
     a Capital Lease Obligation shall be deemed to accrue at an interest rate
     reasonably determined by such Person to be the rate of interest implicit in
     such Capital Lease Obligation in accordance with GAAP consistently applied.
 
     "Consolidated Net Income" means, with respect to any Person for any period,
the aggregate of the Net Income of such Person and its Subsidiaries for such

          (i) the Net Income of any Person that is not a Subsidiary or that is
     accounted for by the equity method of accounting shall be included only to
     the extent of the amount of dividends or distributions paid in cash to the
     referent Person or a Subsidiary thereof;
 
          (ii) the Net Income of any Subsidiary shall be excluded to the extent
     that the declaration or payment of dividends or other distributions by that
     Subsidiary of that Net Income is not at the date of determination permitted
     without any prior governmental approval (which has not been obtained) or,
     directly or indirectly, by operation of the terms of its charter or any
     agreement, instrument, judgment, decree, order, statute, rule or
     governmental regulation applicable to that Subsidiary or its stockholders;
 
          (iii) the Net Income of any Person acquired in a pooling of interests
     transaction for any period prior to the date of such acquisition shall be
     excluded;
 
          (iv) the cumulative effect of a change in accounting principles shall
     be excluded; and
 
          (v) the Net Income of any Unrestricted Subsidiary shall be excluded,
     whether or not distributed to the Company or one of its Subsidiaries.
 
     "Contingent Investment" means, with respect to any Person, any guarantee by
such Person of the performance of another Person or any commitment by such
Person to invest in another Person. Any Investment that consists of a Contingent
Investment shall be deemed made at the time that the guarantee of performance or
the commitment to invest is given, and the amount of such Investment shall be
the maximum monetary obligation under such guarantee of performance or
commitment to invest. To the extent that a Contingent Investment is released or
lapses without payment under the guarantee of performance or the commitment to
invest, such Investment shall be deemed not made to the extent of such release
or lapse. With respect to any Contingent Investment, the payment of the
guarantee of performance or the payment under the commitment to invest shall not
be deemed to be an additional Investment.
 
     "Continuing Directors" means, as of any date of determination, any member
of the Board of Directors of the Company who:
 
          (i) was a member of such Board of Directors on the Issue Date; or

     with the affirmative vote of a majority of the Continuing Directors who

constitute Disqualified Stock but for provisions thereof giving holders thereof
the right to require the Company to repurchase or redeem such Capital Stock upon
the occurrence of a Change of Control occurring prior to the final maturity of
the Senior Subordinated Notes shall not constitute Disqualified Stock if the
change in control provisions applicable to such Capital Stock are no more
favorable to the holders of such Capital Stock than the provisions applicable to
the Senior Subordinated Notes contained in the covenant described under the
subheading "Offer to Purchase Upon a Change of Control" and such Capital Stock
specifically provides that the Company will not repurchase or redeem any such

                   CERTAIN FEDERAL INCOME TAX CONSIDERATIONS
 
     The exchange of Old Notes for New Notes will not constitute a recognition
event for federal income tax purposes. Consequently, no gain or loss will be
recognized by holders upon receipt of the New Notes. The New Notes will have the
same issue date and issue price as the Old Notes. A holder's initial tax basis
in the New Notes will be the same as the holder's basis in the Old Notes
exchanged therefor. Holders will be considered to have held the New Notes from
the time of their original acquisition of the Old Notes.
 
     The following is a summary of the anticipated material United States
federal income tax consequences of the purchase, ownership and disposition of
the Notes. It does not purport to be a complete analysis of all potential
consequences. The summary is based on the Internal Revenue Code of 1986, as
amended (the "Code"), its legislative history, existing and proposed regulations
thereunder, published rulings and court decisions, all as in effect on the date
of this Prospectus and all of which are subject to change at any time. Any such
change may be applied retroactively in a manner that could adversely affect a
holder. This summary applies only to those persons who are the initial holders
of the Notes and who hold the Notes as "capital assets" (generally, assets held
for investment). It does not address the tax consequences to taxpayers who are
subject to special rules (such as financial institutions, tax-exempt
organizations, insurance companies and persons holding Notes as part of a
straddle, hedge or conversion transaction) or aspects of federal income taxation
that may be relevant to a prospective investor based on such investor's
particular tax situation. Moreover, the effect of any applicable state, local or
foreign tax laws is not discussed. Accordingly, purchasers of Notes should
consult their own tax advisors with respect to the particular consequences to
them of the purchase, ownership and disposition of the Notes and the
applicability of any state, local or foreign tax laws, as well as with respect
to the possible effects of changes in federal and other tax laws.
 
INTEREST ON THE SENIOR NOTES
 
     Interest paid on the Senior Notes will generally be taxable to a holder as
ordinary interest income at the time it is accrued or is received in accordance
with the holder's method of accounting for federal income tax purposes. The
9 1/2% Senior Notes were issued with a de minimus amount of original issue
discount ("OID"). Unless a holder elects to include all interest that accrues on
a Senior Note in gross income using the constant yield method, the Senior Notes
will not give rise to OID income for federal income tax purposes.
 
ORIGINAL ISSUE DISCOUNT ON THE SENIOR SUBORDINATED NOTES
 
     General.  For federal income tax purposes, the 12 1/4% Series B Senior
Subordinated Notes will have the same issue date and issue price as the 12 1/4%
Senior Subordinated Notes. Because the 12 1/4% Senior Subordinated Notes were
issued with OID for federal income tax purposes, holders of the 12 1/4% Series B
Senior Subordinated Notes will be required to include OID in income periodically
over the term of the 12 1/4% Series B Senior Subordinated Notes before receipt
of the cash to which such income is attributable.
 
     The amount of OID on a 12 1/4% Series B Senior Subordinated Note will be
the excess of the stated redemption price at maturity of the 12 1/4% Series B
Senior Subordinated Note over its issue price. The issue price of a 12 1/4%
Series B Senior Subordinated Note will be the first price at which a substantial
amount of 12 1/4% Senior Subordinated Notes was sold to the public for money
(excluding sales to bond houses, brokers or others acting in the capacity of
underwriters, placement agents or wholesalers, etc.). The stated redemption
price at maturity of a 12 1/4% Series B Senior Subordinated Note will be the sum
of all payments to be made on such 12 1/4% Series B Senior Subordinated Note,
whether denominated as principal or interest. Accordingly, each 12 1/4% Series B
Senior Subordinated Note will have a substantial amount of OID.
 
     In general, a holder must include in gross income for federal income tax
purposes the sum of the daily portions of OID with respect to a Senior
Subordinated Note for each day during the taxable year or portion of a taxable
year on which such holder holds the Senior Subordinated Note ("Accrued OID").
The daily portion is determined by allocating to each day of any accrual period
a pro rata portion of the OID allocable to that accrual period. The OID
allocable to a full accrual period is an amount equal to the adjusted issue
price of the Senior Subordinated Note at the beginning of the accrual period
multiplied by the yield to maturity of the Senior Subordinated Note. For
purposes of computing OID, Intermedia will use six-month accrual periods
                                       95
<PAGE>   98
 
that end on the days in the calendar year corresponding to the day before the
maturity date of the Senior Subordinated Notes and the date six months prior to
such day, with the exception of an initial short accrual period. The adjusted
issue price of a Senior Subordinated Note at the beginning of any accrual period
is the issue price of the Senior Subordinated Note increased by the Accrued OID
for all prior accrual periods, less any cash payments on the Senior Subordinated
Note made on or before the first day of that accrual period. Under these rules,
holders will generally be required to include in gross income increasingly
greater amounts of OID in each successive accrual period until cash interest is
payable.
 
     Intermedia is required to furnish certain information to the Internal
Revenue Service (the "IRS"), and will furnish annually to record holders of
Senior Subordinated Notes information with respect to OID accruing during the
calendar year. That information will be based on the adjusted issue price of the
Senior Subordinated Notes as if the holders were the original holders of the
Senior Subordinated Notes. Holders who purchase Senior Subordinated Notes for an
amount other than the adjusted issue price and/or on a date other than the last
day of an accrual period will be required to determine for themselves the amount
of OID, if any, they are required to include in gross income for federal income
tax purposes.
 
     Certain Consequences to the Company and to Corporate Holders.  The 12 1/4%
Senior Subordinated Notes constitute "applicable high yield discount
obligations" ("AHYDOs") for federal income tax purposes. Therefore, a portion of
the tax deductions that would otherwise be available to Intermedia in respect of
the Senior Subordinated Notes will be deferred or disallowed, which, in turn,
may reduce the after-tax cash flows of Intermedia. More particularly, Intermedia
will not be entitled to deduct OID that accrues with respect to the Senior
Subordinated Notes until amounts attributable to OID are paid in cash. In
addition, the "disqualified portion" of the OID accruing on the Senior
Subordinated Notes will be characterized as a non-deductible dividend with
respect to Intermedia and will also be treated as a dividend distribution solely
for purposes of the dividends received deduction of Sections 243, 246 and 246A
of the Code with respect to holders that are U.S. corporations. In general, the
"disqualified portion" of OID for any accrual period will be equal to the
product of (i) a percentage determined by dividing the "excess yield" (i.e., the
excess of the yield to maturity of the Senior Subordinated Notes over 11.17% by
the yield to maturity and (ii) the OID for the accrual period. Subject to
otherwise applicable limitations, a U.S. corporate holder will be entitled to a
dividends received deduction (generally at a 70 percent rate) with respect to
the disqualified portion of the Accrued OID if Intermedia has sufficient current
or accumulated "earnings and profits." To the extent that the Company's earnings
and profits are insufficient, any portion of the OID that otherwise would have
been recharacterized as a dividend for purposes of the dividends received
deduction will continue to be taxed as ordinary OID income in accordance with
the rules described above in "Original Issue Discount on the Senior Subordinated
Notes -- General."
 
EXCHANGE OFFER; REGISTRATION RIGHTS; LIQUIDATED DAMAGES
 
     Neither the exchange of Old Notes for new Notes in the Exchange Offers nor
the registration of the old Notes or new Notes pursuant to a shelf registration
statement should be a taxable event for United States federal income tax
purposes.
 
     Intermedia intends to take the position that Liquidated Damages payable as
the result of a Registration Default, if any, will be taxable to a holder as
ordinary income in accordance with such holder's method of accounting for tax
purposes. The IRS, however, may take a different position, which could affect
the timing of both a holder's income and Intermedia's deduction with respect to
such Liquidated Damages.
 
DISPOSITION OF THE NOTES
 
     Generally, any sale, redemption or other taxable disposition of a Note will
result in taxable gain or loss equal to the difference between the sum of the
amount of cash and the fair market value of property received (other than
amounts attributable to accrued but unpaid stated interest on a Senior Note) and
the holder's adjusted tax basis in the Note. An initial holder's adjusted tax
basis for determining gain or loss on a sale or other disposition of a Senior
Subordinated Note will equal the cost of the Senior Subordinated Note to such
holder, increased by any Accrued OID includible in such holder's gross income
and decreased by the amount
 
                                       96
<PAGE>   99
 
of any cash payments received by such holder (regardless of whether such
payments are denominated as principal or interest). Any gain or loss upon a sale
or other disposition of a Note will generally be capital gain or loss, and will
be long-term capital gain or loss if the Note has been held by the holder for
more than one year.
 
     Holders should be aware that the resale of a Note may be affected by the
"market discount" rules of the Code, under which a subsequent purchaser
acquiring a Note at a market discount generally would be required to include as
ordinary income a portion of gain realized upon the disposition or retirement of
such Note to the extent of the market discount that accrued while the Note was
held by such purchaser.
 
BACKUP WITHHOLDING
 
     A holder may be subject, under certain circumstances, to backup withholding
at a 31 percent rate with respect to payments of interest and OID received on,
and proceeds from the sale (through a broker) of, a Note. Backup withholding
generally applies only if the holder (i) fails to furnish his or her social
security or other taxpayer identification number ("TIN") to Intermedia in the
required manner, (ii) furnishes an incorrect TIN and the IRS so notifies
Intermedia, (iii) is notified by the IRS that he or she has failed to report
properly payments of interest or dividends and the IRS has notified Intermedia
that he or she is subject to withholding, or (iv) fails, under certain
circumstances, to provide a certified statement, signed under penalty of
perjury, that the TIN provided is his or her correct number and that he or she
is not subject to backup withholding.
 
     Any amount withheld from a payment to a holder under the backup withholding
rules is allowable as a credit against such holder's federal income tax
liability, provided that the required information is furnished to the IRS.
Certain holders (including, among others, corporations) are not subject to
backup withholding. Holders should consult their tax advisors as to their
qualification for exemption from backup withholding and the procedure for
obtaining such an exemption.
 
                              PLAN OF DISTRIBUTION
 
     Each broker-dealer that receives New Notes for its own account pursuant to
the Exchange Offers must acknowledge that it will deliver a prospectus in
connection with any resale of the New Notes. This Prospectus, as it may be
amended or supplemented from time to time, may be used by a broker-dealer in
connection with resales of New Notes received in exchange for Old Notes acquired
as a result of market-making activities or other trading activities. We have
agreed that for a period expiring on the earlier of (a) the date that all
Transfer Restricted Securities cease to be Transfer Restricted Securities and
(b) 365 days after the date the Exchange Offers are completed we will make this
Prospectus, as amended or supplemented, available to any broker-dealer for use
in connection with any such resale.
 
     We will not receive any proceeds from any sale of New Notes by
broker-dealers. New Notes received by broker-dealers for their own account
pursuant to the Exchange Offers may be sold from time to time in one or more
transactions in the over-the-counter market, in negotiated transactions, through
the writing of options on the New Notes or a combination of such methods of
resale, at market prices prevailing at the time of resale, at prices related to
such prevailing market prices or negotiated prices. Any such resale may be made
directly to purchasers or to or through brokers or dealers who may receive
compensation in the form of commissions or concessions from any such
broker-dealer and/or the purchasers of any New Notes. Any broker-dealer that
resells New Notes that were received by it for its own account pursuant to the
Exchange Offers and any broker-dealer that participates in a distribution of New
Notes may be deemed to be an "underwriter" within the meaning of the Securities
Act and any profit on any resale of New Notes and any commissions or concessions
received by any such persons may be deemed to be underwriting compensation under
the Securities Act. The Letter of Transmittal states that by acknowledging that
it will deliver and by delivering a prospectus, a broker-dealer will not be
deemed to admit that it is an "underwriter" within the meaning of the Securities
Act.
 
     We have not entered into any arrangement or understanding with any person
to distribute the New Notes to be received in the Exchange Offers and to the
best of our information and belief, each person participating
                                       97
<PAGE>   100
 
in the Exchange Offers is acquiring the New Notes in its ordinary course of
business and has no arrangement or understanding with any person to participate
in the distribution of the New Notes to be received in the Exchange Offers.
