                 INTERMEDIA COMMUNICATIONS INC. AND SUBSIDIARIES
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                   (UNAUDITED)

Note 1   Basis of Presentation

           The accompanying unaudited condensed consolidated financial
         statements have been prepared in accordance with generally accepted
         accounting principles for interim financial information and with the
         instructions to Form 10-Q and Article 10 of Regulation S-X.
         Accordingly, they do not include all of the information and footnotes
         required by generally accepted accounting principles for complete
         financial statements. In the opinion of management, all adjustments
         (consisting of normal recurring accruals) necessary to present fairly
         the information set forth therein have been included. The accompanying
         condensed consolidated financial statements should be read in
         conjunction with the consolidated financial statements and footnotes
         included in the Annual Report on Form 10-K (the "Form 10-K") of
         Intermedia Communications Inc.
         ("Intermedia" or the Company") for the year ended December 31, 1997.

           Operating results for the three-month period ended March 31, 1998 are
         not necessarily an indication of the results that may be expected for
         the year ending December 31, 1998.

         Recently Issued Accounting Standards

           In June 1997, the Financial Accounting Standards Board issued
         Statement of Financial Accounting Standards No. 131, Disclosures about
         Segments of an Enterprise and Related Information (SFAS 131), which
         supersedes Financial Accounting Standards No. 14. SFAS 131 uses a
         management approach to report financial and descriptive information
         about a Company's operating segments. Operating segments are
         revenue-producing components of the enterprise for which separate
         financial information is produced internally for the Company's
         management. SFAS 131 is effective for fiscal years beginning after
         December 31, 1997, but is not required to be applied to interim
         financial statements in the initial year of its application. Management
         is currently assessing the impact of this Standard.

Note 2   Business Acquisitions

           On March 10 1998, the Company completed its acquisition of Shared
         Technologies Fairchild Inc. ("Shared"), a shared tenant communications
         services provider. The operating results of Shared are included in the
         Company's consolidated financial statements commencing on January 1,
         1998, the effective date of the acquisition. Imputed interest of $5.1
         million was recorded based on the cash consideration paid after the
         effective date of the acquisition in the first quarter of 1998 and the
         cost for Shared was reduced accordingly. Aggregate cash consideration
         for the acquisition was approximately $769.3 million, including $62.3
         million of certain transaction expenses and fees relating to certain
         agreements. The acquisition was accounted for by the purchase method of
         accounting, with the purchase price allocated to the fair value of
         assets acquired and liabilities assumed, principally goodwill. In
         conjunction with this allocation, the Company has engaged an
         independent valuation related to intangible assets acquired. Based on
         the preliminary valuation, the amount allocated to in-process research
         and development ($85 million) was recorded as a one-time charge to
         operations in the accompanying consolidated statements of operations
         because the technology was not fully developed and had no future
         alternative use. The allocation of the purchase price to other assets
         and liabilities is tentative pending management's completion of the
         valuation of the purchased assets and liabilities.

           On March 31, 1998, the Company acquired LDS Communications Group
         ("LDS"), a regional interexchange carrier. The operating results of LDS
         for the one day of ownership during the first quarter of 1998 are
         considered immaterial and will be included in the Company's
         consolidated statement of operations commencing on April 1, 1998. The
         balance sheet as of March 31, 1998 has been included in the Company's
         consolidated balance sheet as of March 31, 1998. Aggregate
         consideration for the acquisition was approximately $16.4 million in
         cash, plus 2,679,874 shares of the Company's Common Stock, par value
         $.01 per share (the "Common Stock"), valued at approximately $137.2
         million and the retirement of $15 million in LDS's long-term debt. The
         acquisition was accounted for by the purchase method of accounting,
         with the purchase price to be allocated to the fair value of assets
         acquired and liabilities 


                                       6
<PAGE>   7


         assumed, principally goodwill. The allocation of the purchase price is
         tentative pending management's completion of the valuation of the
         purchased assets and liabilities.

           The following unaudited pro forma results of operations present the
         consolidated results of operations as if the acquisitions of DIGEX,
         Shared and LDS had occurred on January 1, 1997 These proforma results
         do not purport to be indicative of the results that actually would have
         occurred if the acquisition had been made as of that date or of results
         which may occur in the future.

           On April 30, 1998, the Company completed the acquisition of privately
         held National Telecommunications of Florida, Inc. and NTC, Inc.
         (collectively, "National"), an emerging switch-based competitive local
         exchange carrier and established interexchange carrier. Aggregate
         consideration for the acquisition was approximately $63.1 million in
         cash, including the repayment of approximately $2.8 million in National
         debt and $.8 million in acquisition related costs incurred to date,
         plus 1,454,898 shares of Common Stock, valued at approximately $88.7
         million.

Note 3   Long-Term Debt and Capital Lease Obligations

           In January 1998, the over-allotment option with respect to the 8.5%
         Senior Notes was exercised and the Company sold an additional $50
         million principal amount of 8.5% Senior Notes. Net proceeds to the
         Company amounted to approximately $48.8 million.

           As disclosed in the Company's annual report on Form 10-K for the year
         ended December 31, 1997, the Company is party to various capital lease
         agreements for fiber optic cable, underground conduit equipment and
         utility poles which extend through the year 2015.

           In March 1998, the Company and Williams Communications, Inc.
         ("Williams") executed a Capacity Purchase Agreement which provides the
         Company with the right to purchase transmission capacity on a
         non-cancelable indefeasible right of use basis on the Williams fiber
         network for the next 20 years. The agreement covers approximately
         14,000 route miles of existing and planned network facilities. The
         capitalized asset, consisting of the Company's rights to use network
         facilities, including but not limited to, fiber, optronics/electronics,
         digital encoders/decoders, telephone lines and microwave facilities, in
         the amount of $417 million, is being depreciated over the 20-year
         estimated useful life of the primary underlying network asset, the
         fiber.

           Future minimum payments under the capital leases at March 31, 1998
         are as follows:

Note 4   Comprehensive Income

           In June 1997, the Financial Accounting Standards Board issued
         Statement of Financial Accounting Standards No. 130, Reporting
         Comprehensive Income (SFAS 130). SFAS 130 requires that total
         comprehensive income be disclosed with equal prominence as net income.
         Comprehensive income is defined as changes in stockholders' equity
         exclusive of transactions with owners such as capital contributions and
         dividends. Adoption of SFAS 130 had no impact on the Company as
         comprehensive income for the Company, as defined by SFAS 130, equals
         net income for the quarter ended March 31, 1998.

Note 6   Contingencies

           On June 20, 1997, two purported class action complaints were filed in
         the Court of Chancery of the State of Delaware in and for New Castle
         County respectively by TAAM Associates, Inc. and David and Chaile
         Steinberg (the Complaints), purported stockholders of DIGEX on behalf
         of all non-affiliated common stockholders of DIGEX against Intermedia,
         DIGEX and the Directors of DIGEX (the DIGEX Directors). The Complaints
         allege that the DIGEX Directors violated their fiduciary duties to the
         public stockholders of DIGEX by agreeing to vote in favor of the merger
         between DIGEX and a wholly owned subsidiary of Intermedia (the Merger)
         and that Intermedia knowingly aided and abetted such violation by
         offering to retain DIGEX management in their present positions and
         consenting to stock option grants to certain executive officers of
         DIGEX. The Complaints sought a preliminary and permanent injunction
         enjoining the Merger but no applications were made for such injunctions
         prior to consummation of the Merger on July 



                                       8
<PAGE>   9

         11, 1997. In addition, the Complaints seek cash damages from DIGEX
         Directors. In August 1997, a motion to dismiss the Complaints was filed
         on behalf of Intermedia, DIGEX and the DIGEX Directors. The action has
         been dormant since that time.

           These cases are in the early stages and no assurance can be given as
         to their ultimate outcome. Intermedia, after consultation with its
         counsel, believes that there are meritorious factual and legal defenses
         to the claims in the Complaints. Intermedia intends to defend
         vigorously the claims in the Complaints.

           The Company is not a party to any other pending legal proceedings
         except for various claims and lawsuits arising in the normal course of
         business. The Company does not believe that these normal course of
         business claims or lawsuits will have a material effect on the
         Company's financial condition, results of operations or cash flows.

           The Company maintains interconnection agreements with incumbent local
         exchange carriers (ILECs) in Florida, Georgia, and North Carolina.
         These contracts govern the reciprocal amounts to be billed by
         competitive carriers for terminating local traffic of internet service
         providers (ISPs) in each state. During 1997, the Company recognized
         revenue from these ILECS of approximately $10.2 million for these
         services. During the first quarter of 1998, the Company recognized an
         additional $5.4 million in revenue from these services. No payments
         were received as the ILECs are disputing the Company's right to bill
         for such services.

           Management believes the issue related to mutual compensation for
         Internet traffic to be an industry wide matter that will ultimately be
         resolved on a state-by-state basis. To date, twenty of twenty-one state
         commissions that have ruled on the issue found that ILECs must pay
         compensation to competitive carriers for local calls to ISPs located on
         competitive carriers' networks. A contrary ruling by an administrative
         law judge in Oklahoma is currently being appealed. A number of other
         state commissions currently have proceedings pending to consider this
         matter. Management is pursuing this matter vigorously and believes the
         ILECs will ultimately pay all amounts in full.

Note 7   Subsequent Event

           On April 29, 1998, the Company announced that it has committed
         resources to plan and implement the integration of acquired businesses
         to maximize the synergies that will be realized and to reduce future
         costs. In connection with the integration and realignment of the
         Company's businesses and operating structure, the Company expects to
         record a one-time restructuring charge later this year, the amount and
         timing of which is subject to the completion of a detailed
         restructuring program.

ITEM 2.       Management's Discussion and Analysis of Financial Condition and 
              Results of Operations

  The following discussion should be read in conjunction with the condensed
consolidated financial statements and notes thereto included herewith, and with
the Company's Management's Discussion and Analysis of Financial Condition and
Results of Operations and audited consolidated financial statements and notes
thereto included in the Company's Annual Report on Form 10-K for the year ended
December 31, 1997 filed with the Securities and Exchange Commission.

OVERVIEW

  Intermedia has experienced continuous revenue growth since its inception in
1986. Since 1992, the Company has experienced an accelerating rate of revenue
growth. Building from its original base in Florida, Intermedia now provides
integrated telecommunications services nationally with a focus on customers who
have a substantial presence in the eastern United States. Through a combination
of internally generated growth and targeted acquisitions the Company has
expanded its service territory and dramatically increased its customer base.

  Intermedia's customers include a broad range of business and government end
users and, to a lesser extent, ISPs and other carriers. The Company delivers
local network services, including local exchange service, primarily through
Company owned local and long distance switches and over a Company owned or
leased digital transport network. Often, leasing facilities enables the Company
to more rapidly initiate service to customers, reduces the risk of network
construction or acquisition and potentially improves cash flow due to the
reduction or deferment of capital expenditures. The Company also utilizes the
resale of ILEC local exchange services as a means of rapidly entering new
markets and establishing customer relationships. These resale customers may
later be migrated onto the Company's switches and network. The Company offers
enhanced data services to its customers on an extensive intercity network that
connects its customers, either through its own network or through other
carriers, to locations throughout the country and internationally. Through its
433 NNIs and 150 data switches, Intermedia has established the most densely
deployed frame relay switching network in the nation. The Company's nationwide
interexchange network, which it is upgrading to provide ATM capability, carries
both its data network traffic and its voice network traffic.

   At its inception, Intermedia provided special access and private line
services to IXCs. In 1988, Intermedia was the first telecommunications provider
in Florida to begin providing special access and private line services to
business customers. In 1991, Intermedia began offering specialized integration
services such as construction of campus LANs, and in 1992, Intermedia introduced
its first enhanced data services based on frame relay technology, providing
flexible capacity and highly reliable end-to-end data service. The Company began
offering interexchange long distance service in December 1994, Internet services
in 1995, local exchange services in 1996 and integrated voice/data services via
Single-T(sm) in 1997. The pace with which the Company has introduced new service
offerings has enabled it to achieve substantial growth, expand its base of
customers and diversify its sources of revenue. The Company believes that
business and government customers will continue to account for a substantial
share of its revenue, because of Intermedia's ability to offer such customers
integrated, cost-effective telecommunications solutions. The Company believes
that during the first few years of local exchange competition, some IXCs may
enter the local exchange market by becoming resellers of the Company's local
services. If the IXCs pursue a resale strategy, the amount of revenue the
Company realizes from carriers may increase during this period, although the
Company does not depend on these IXC resale revenues to satisfy its business
plan.

   From 1992 through 1995, the Company achieved positive EBITDA and increased
its revenue base substantially. EBITDA consists of earnings before interest,
income taxes, depreciation, amortization and one-time and certain non-recurring
charges such as the charge for in-process R&D. As a result of significant
investments in the resources necessary to launch local exchange services and
expand enhanced data services, the Company's EBITDA was negative for 1997 and
the first quarter of 1998. The Company expects EBITDA to be positive for 1998.
The development of the Company's business and the expansion of its network and
systems infrastructure have resulted in substantial capital expenditures and net
losses during this period of its operations. Network operating costs,
administration and maintenance of facilities, depreciation of network capital
expenditures and sales, general and administrative costs will continue to
represent a large portion of the Company's expenses for the next several years.
In addition, the Company is experiencing rapid growth in marketing and selling
expenses consistent with the addition of new customers and an increased level of
selling and marketing activity. All of the marketing and selling expenses
associated with the acquisition of new customers are expensed as they are
incurred even though these customers are



                                       10
<PAGE>   11

expected to generate recurring revenue for the Company for several years. The
continued expansion of the Company's networks in preparation for new customers
and the marketing of services to new and existing customers is therefore
adversely impacting EBITDA of the Company in the near term. The Company
anticipates that as its customer base grows, incremental revenues will be
greater than incremental operating expenses.

  On January 29, 1998, the Company announced a definitive multi-year agreement
to become U S West Communication's ("US West") preferred interLATA data services
provider. Under the term's of this preferred provider agreement, the Company
will grant US West a license to utilize and market the Company's portfolio of
enhanced data services.

  On March 10 1998, the Company completed its acquisition of Shared, a shared
tenant communications services provider. Aggregate cash consideration for the
acquisition was approximately $769.3 million, including $62.3 million of certain
transaction expenses and fees relating to certain agreements with the final
payment made March 10, 1998 and funded with the Company's existing cash reserves
in March 1998. The operating results of Shared are included in the Company's
consolidated financial statements commencing on January 1, 1998.

  On March 31, 1998, the Company acquired LDS, a regional interexchange carrier.
Aggregate consideration for the acquisition was approximately $16.4 million in
cash, plus 2,679,874 shares of Common Stock, valued at approximately $137.2
million and the retirement of $15 million in LDS's long-term debt. The cash
portion of the acquisition was funded with the Company's existing cash reserves
in March 1998. . The operating results of LDS for the one day of ownership
during the first quarter of 1998 are considered immaterial and will be included
in the Company's consolidated statement of operations commencing on April 1,
1998. The balance sheet as of March 31, 1998 has been included in the Company's
consolidated balance sheet as of March 31, 1998.

  In March 1998, the Company and Williams Communications, Inc. ("Williams")
executed a Capacity Purchase Agreement which provides the Company with the right
to purchase transmission capacity on a non-cancelable indefeasible right of use
basis on the Williams fiber network for the next 20 years. The agreement covers
approximately 14,000 route miles of existing and planned network facilities.

  On April 29, 1998, the Company announced that it has committed resources to
plan and implement the integration of acquired businesses to maximize the
synergies that will be realized and to reduce future costs. In connection with
the integration and realignment of the Company's businesses and operating
structure, the Company expects to record a one-time restructuring charge later
this year, the amount and timing of which is subject to the completion of a
detailed restructuring program.

  On April 30, 1998, the Company completed the acquisition of privately held
National, an emerging switch-based competitive local exchange carrier and
established interexchange carrier. Aggregate consideration for the acquisition
was approximately $63.1 million in cash, including the repayment of
approximately $2.8 million in National debt and $.8 million in acquisition
related costs incurred to date, plus 1,454,898 shares of Common Stock, valued at
approximately $88.7 million.

PLAN OF OPERATION

  In 1998, the Company believes that its growth will be balanced among its
local exchange, long distance and enhanced data services. Based on the Company's
analysis of FCC data and its knowledge of the industry, the Company estimates
that the market for local exchange, long distance and data services was
approximately $34 billion in 1997 in the Company's service territory. As a
result of the Company's planned expansion in 1998, including the consummation of
the acquisitions of Shared, LDS and National, the Company expects to be
positioned to provide these services in markets with a total opportunity of more
than $90 billion by the end of 1998.

  In order to develop its business more rapidly and efficiently utilize its
capital resources, the Company plans to use the existing fiber optic
infrastructure of other providers in addition to using its own existing
networks. The Company believes transport provided on fiber optic systems has
become commodity-like, and its capital expenditures are better focused on
intelligent switching and other more strategic network components required to
implement a Packet/Cell Switched Network. While the Company will use significant
amounts of capital to deploy enhanced data and voice switches on a demand driven
basis in selected markets, Intermedia believes its substantial existing network
capacity should enable it to add new customers and provide additional services
that will result in 



                                       11
<PAGE>   12

increased revenues with lower incremental costs and, correspondingly, improve
its EBITDA. For example, selling additional services, such as local exchange
services, to existing or new customers allows the Company to utilize unused
portions of the capacity inherent in its existing fiber optic networks. This
operating leverage increases the utilization of the network with limited
additional capital expenditures. The Company's strategy to offer a full
complement of telecommunications services is designed to enable the Company to
take advantage of the operating leverage of its networks.

Quarter Ended March 31, 1998 Compared to Quarter Ended March 31, 1997:

         Revenue

         Total revenue increased 211% to $136.8 million for the first quarter of
1998 compared to $43.9 million for the same period in 1997. This increase was
principally through the acquisitions of DIGEX and Shared, the introduction of
new services and the increased focus of the Company's sales force on offering a
full suite of telecommunications services to an expanding market.

         Local network services revenue increased 546% to $33.7 million for the
first quarter of 1998 compared to $5.2 million for the same period in 1997. This
increase was principally due to the acquisition of Shared during the first
quarter of 1998 and the continued rollout of local exchange services into
additional markets. The number of access line equivalents has increased by
203,202 since April 1, 1997, of which 111,600 are related to the acquisition of
Shared. The Company has received CLEC certification in 37 states plus the
District of Columbia as of the end of the first quarter of 1998. Local network
services revenue will be positively impacted starting in the second quarter of
1998 by the acquisition of National which closed on April 30, 1998.

         Enhanced data services revenue increased 223% to $36.5 million for the
first quarter of 1998 compared to $11.3 million for the same period in 1997.
This increase was principally from the acquisition of DIGEX in July 1997 and the
expansion of the Company's enhanced data network by 50 switches, 140 NNI
connections and 10,342 new frame relay nodes since April 1, 1997. In addition,
the number of frame relay cities has increased by 1,620 during the same time
period. Enhanced data services revenue will be positively impacted starting in
the second quarter of 1998 by the acquisition of LDS which closed on March 31,
1998.

         Interexchange services revenue increased 75% to $44.8 million for the
first quarter of 1998 compared to $25.5 million for the same period in 1997.
This increase was principally from the acquisition of Shared during the first
quarter of 1998, strong growth in long distance switched revenue and steady
growth in interLATA transport. Long distance billable minutes have increased to
184.2 million minutes for the first quarter of 1998 compared to 87.5 million
minutes for the same period in 1997. Interexchange revenues will be negatively
impacted by an estimated $2 million per month by the Company's decision to exit
the low margin wholesale international long distance segment starting in the
second quarter of 1998. Interexchange revenues will be positively impacted
starting in the second quarter of 1998 by the acquisitions of LDS and National.

         Integration services revenue increased 1,066% to $21.8 million for the
first quarter of 1998 compared to $1.9 million for the same period in 1997. This
increase was principally due to the acquisition of Shared during the first
quarter of 1998.

         Operating Expenses

         Total operating expenses increased 319% to $271.5 million for the first
quarter of 1998 compared to $64.8 million for the same period in 1997. The
increase was principally from the acquisition of DIGEX in July 1997, the
acquisition of Shared in the first quarter of 1998, increased expenditures to
prepare for the expected increase in volume from the US West agreement,
increased network operations expenditures related to increased traffic and
increased expenditures related to the implementation of manual processes and
procedures to augment some of the back-office functions which are at or near
capacity from an automation perspective. In addition, there has been significant
expansion of the Company's owned and leased networks and the continued expansion
in personnel to sustain and support the Company's growth. Operating expenses
will be impacted starting in the second quarter by the acquisition of both LDS
and Shared.




                                       13
<PAGE>   14

         Network operations expenses increased 138% to $71.5 million for the
first quarter of 1998 compared to $30.0 million for the same period in 1997. The
increase was principally from the acquisition of DIGEX in July 1997 and the
acquisition of Shared in the first quarter of 1998. In addition, the Company has
incurred increases in leased network capacity that is associated with the growth
of local network service, enhanced data service and interexchange service
revenues. The Williams agreement is expected to positively impact network
operations expenses by eliminating certain backbone network leases that were
accounted for as operating leases.

         Facilities administration and maintenance expenses increased 167% to
$15.0 million for the first quarter of 1998 compared to $5.6 million for the
same period in 1997. The increase was principally from the acquisition of DIGEX
in July 1997 and the acquisition of Shared in the first quarter of 1998. In
addition, the increase resulted from the expansion of the Company's owned and
leased network capacity, increases in maintenance expense due to the network
expansion and increased payroll expenses related to hiring additional
engineering and operations staff to support and service the expanding network,
including the expected increase in volume on account of the US West agreement.

         Cost of Goods Sold increased 978% to $13.7 million for the first
quarter of 1998 compared to $1.3 million for the same period in 1997. This
increase was principally due to the acquisition of Shared during the first
quarter of 1998.

         Selling, general and administrative expenses increased 137% to $46.3
million for the first quarter of 1998 compared to $19.5 million for the same
period in 1997. The increase was principally from the acquisition of DIGEX in
July 1997 and the acquisition of Shared in the first quarter of 1998. In
addition, the increase was due to the Company's continued growth, the increase
in costs to prepare for the US West agreement, and represented an increase in
the sales, marketing, management information services and customer service
personnel, one time expenditures for employee recruitment, relocation, training
and increased commissions relating to the rise in revenues for these periods.
These expenses were also negatively impacted from the increased expenditures
related to the implementation of manual processes and procedures to augment some
of the back-office functions which are at or near capacity from an automation
perspective.

         Depreciation and amortization expenses increased 381% to $39.9 million
for the first quarter of 1998 compared to $8.3 million for the same period in
1997. This increase was principally from additions to telecommunications
equipment placed in service since April 1, 1997, relating to ongoing network
expansion, as well as the DIGEX acquisition, the Shared acquisition and the LDS
acquisition which contributed, based on preliminary estimates, approximately
$113 million, $629 million and $141 million of goodwill, respectively.
Depreciation and amortization expense is expected to increase in future periods
as the Company expands the network, depreciates the capital assets leased from
Williams and amortizes goodwill associated with the businesses acquired.

         Charge for in-process Research & Development of $85 million represents
the amount of purchased in-process research and development associated with the
purchase of Shared. This cost was recorded as a one-time charge to earnings in
the first quarter of 1998.

         Interest Expense

         Interest expense increased 345% to $49.3 million for the first quarter
of 1998 compared to $11.1 million for the same period in 1997. This increase
primarily resulted from interest expense on approximately $1.3 billion of senior
notes issued by the Company in 1997 and in January 1998, the non-cash imputed
interest charge of $5.1 million related to the acquisition of Shared and the
interest related to the capital lease with Williams. Included in 1998 interest
expense is $18.5 million of debt discount amortization and $.9 million of
deferred loan cost amortization, both of which are non-cash items. Interest
expense capitalized in connection with the Company's construction of
telecommunications equipment amounted to approximately $2.0 million and $.8
million for the three months ended March 31, 1998 and 1997, respectively.

         Other Income

         Other income increased 140% to $10.7 million for the first quarter of
1998 compared to $4.5 million for the same period in 1997. This increase was
primarily the result of interest earned on the cash available from the 



                                       14
<PAGE>   15

proceeds of the issuance of securities in 1997 and the exercise of the
over-allotment option with respect to the 8.5% Senior Notes in January 1998.

         Net Loss

         Net loss increased 532% to $173.3 million for the first quarter of 1998
compared to $27.4 million for the same period in 1997. The increase was
principally from the acquisition of DIGEX in July 1997, and the acquisition of
Shared in the first quarter of 1998. In addition, the increased operating
expenses resulting from the expansion of the network, increased selling, general
and administrative costs, the charge for in-process R&D, and increased interest
costs contributed to the increase.

         Preferred Stock Dividends and Accretions

         Preferred stock dividends and accretions increased 451% to $18.6
million for the first quarter of 1998 compared to $3.4 million for the same
period in 1997. The increase was due to the issuance of the three series of
preferred stock in March 1997, July 1997 and October 1997. Preferred stock
dividends were paid in the form of Common Stock and Preferred Stock. No cash
dividends are expected by management in the foreseeable future.

         EBITDA

         EBITDA increased 21.3% to $(9.8) million for the first quarter of 1998
compared to $(12.5) million for the same period in 1997. This increase was the
result of the acquisition of Shared and the decrease in network operation
expenses, facilities administration and maintenance expenses and selling,
general and administrative expenses as a percentage of revenue in the first
quarter of 1998 as compared to the same period in 1997.

Liquidity and Capital Resources

         The Company's operations have required substantial capital investment
for the purchase of telecommunications equipment and the design, construction
and development of the Company's networks. Capital expenditures for the Company
were approximately $77 million and $33 million for the three months ended March
31, 1998 and 1997, respectively, excluding capital leases and telecommunications
equipment acquired in connection with business acquisitions. The Company expects
that it will continue to have substantial capital requirements in connection
with the (i) expansion and improvement of the Company's existing networks, (ii)
design, construction and development of new networks, (iii) connection of
additional buildings and customers to the Company's networks, (iv) purchase of
switches necessary for local exchange services and expansion of interexchange
services and (v) continued development of the Company's enhanced data services.
During the first quarter of 1998, the Company utilized approximately $367
million of its available cash to complete the Shared acquisition and
approximately $31.5 million of its available cash to complete the LDS
acquisition. In addition, the Company utilized approximately $63.1 million of
its available cash to complete the acquisition of National in April 1998.

     The Company has funded a substantial portion of these expenditures through
the public and private sale of debt and equity securities. From inception
through December 31, 1996, the Company raised approximately $212.6 million in
net proceeds from the sale of Common Stock, including Common Stock issued in
connection with certain acquisitions, and $324.6 million in net proceeds from
the sale of senior notes. During 1997 the Company raised approximately $957.5
million in net proceeds from the sale of senior notes and approximately $648.6
million in net proceeds from the sale of three series of preferred stock. All of
these issued series of preferred stock include provisions that may cause the
securities to be redeemed upon a change of control of the Company. As a result
of these redemption provisions, the Company is required to classify the
preferred stock outside of stockholder's equity on the Company's balance sheet
at March 31, 1998. Additionally, none of the outstanding series of preferred
stock require the Company to pay cash dividends in the foreseeable future.

     The substantial capital investment required to build the Company's network
has resulted in negative cash flow after consideration of investing activities
over the last five year period. This negative cash flow after investing
activities is a result of the requirement to build a substantial portion of the
Company's network in anticipation of connecting revenue generating customers.
The Company expects to continue to produce negative cash flow after investing
activities for the next several years due to the continuous expansion and the
development of the Company's networks. Until sufficient cash flow after
investing activities is generated, the Company will be required to utilize its



                                       15
<PAGE>   16

current and future capital resources to meet its cash flow requirements,
including the issuance of additional debt and/or equity securities.

     In response to the new pro-competitive telecommunications environment, the
Company has accelerated and expanded its capital deployment plan to allow for an
increased level of demand-driven capital spending necessary to more rapidly
exploit the market opportunity in the local exchange market. The Company expects
to commit substantial amounts of funds to upgrade its existing network in order
to switch traffic within the local service area in those states where it is
currently permitted to provide such services. As of March 31, 1998, the Company
was certified as a CLEC in 37 states and the District of Columbia, allowing the
Company to provide local exchange services in those markets, and is currently
seeking CLEC certification in the remaining 13 states. In addition, the Company
expects to expend capital for the further development of the Company's enhanced
data service and interchange service offerings.

     A portion of the Company's expansion has occurred, and may continue to
occur, by means of acquisitions. In July 1997, the Company acquired DIGEX, a
leading nationwide business ISP. The aggregate cash consideration for the
acquisition was approximately $160 million and was funded with the Company's
then existing cash reserves. In March 1998, the Company acquired Shared. The
total aggregate cash consideration for Shared was approximately $769 million,
which was paid out in 1998 and 1997, including certain transaction expenses and
fees relating to certain agreements. This amount includes repayment of $123.5
million of Shared's outstanding bank debt (including accrued interest and
outstanding fees) in connection with the consummation of the acquisition. In
March 1998, the Company completed its acquisition of LDS for a purchase price of
approximately $169 million, of which approximately $137 million was paid in
Common Stock and approximately $31.5 million was paid in cash, including the
repayment of approximately $15 million of LDS debt.

     On April 30, 1998, the Company completed the acquisition of privately held
National, an emerging switch-based competitive local exchange carrier and
established interexchange carrier. The aggregate consideration for the
acquisition was approximately $151.8 million, of which approximately $88.7
million was paid by delivering approximately 1.5 million shares of Common Stock
and approximately $63.1 million was paid in cash, including the repayment of
approximately $2.8 million in National debt and $.8 million in acquisition
related costs incurred to date.

     The Company expects that it will be EBITDA positive for 1998 and that its
1998 capital requirements (estimated as approximately $400 million which does
not include the non-cash Williams network capacity purchase) will be funded from
available cash, cash generated from its 1998 operations, the bank credit
facility discussed below and/or other offerings of the Company's debt
securities. Continued funding of the Company's accelerated and expanded capital
deployment plan will require the Company to raise additional debt or equity
capital by the end of 1999. Depending on market conditions, the Company may
determine to raise additional capital before such time. There can be no
assurance, however, that the Company will be successful in raising sufficient
debt or equity on terms that it will consider acceptable. Moreover, the terms of
the Company's outstanding indebtedness and preferred stock impose certain
restrictions upon the Company's ability to incur additional indebtedness or
issue additional preferred stock. The Company has entered discussions with
several banks for a bank credit facility, although there can be no assurance
that a bank facility on terms satisfactory to the Company will be established.

     The Company has from time to time held, and continues to hold, preliminary
discussions with (i) potential strategic investors (i.e. investors in the same
or a related business) who have expressed an interest in making an investment in
or acquiring the Company, (ii) potential joint venture partners looking toward
formation of strategic alliances that would expand the reach of the Company's
network or services without necessarily requiring an additional investment in or
by the Company and (iii) companies that represent potential acquisition
opportunities for the Company. There can be no assurance that any agreement with
any potential strategic investor, joint venture partner or acquisition target
will be reached nor does management believe that any thereof is necessary to
successfully implement its strategic plans.

Impact of Year 2000

     The Year 2000 issue is the result of computer-controlled systems using two
digits rather than four to define the applicable year. For example, computer
programs that have time-sensitive software may recognize a date using "00" as
the year 1900 rather than the year 2000. This could result in a system failure
or miscalculations causing 



                                       16
<PAGE>   17

disruptions of operations, including, among other things, a temporary inability
to process transactions, send invoices, or engage in similar normal business
activities.

     Based on an assessment, the Company determined that it will be required to
modify or replace portions of its software and hardware so that its systems will
function properly with respect to dates in the year 2000 and thereafter. The
Company presently believes that with modifications to existing software and
conversions to new software and hardware, the Year 2000 issue will not pose
significant operational problems for its systems. However, if such modifications
and conversions are not made, or are not completed in timely fashion, the Year
2000 problems could have a material impact on the operations of the Company.

     The Company is in the process of contacting all of its significant
suppliers and large customers to determine the extent to which the Company's
interface systems are vulnerable to those third parties' failure to remediate
their own Year 2000 issues. The Company's total Year 2000 project cost and
estimates to complete include the estimated costs and time associated with the
impact of third party Year 2000 issues based on presently available information.
However, there can be no guarantee that the systems of other companies on which
the Company's systems rely will be timely converted and would not have a
material adverse effect on the Company's systems.

     The Company will utilize both internal and external resources to reprogram,
or replace, and test the software and hardware for Year 2000 compliance. The
Company's objective is to complete the Year 2000 project not later than December
31, 1998, which is prior to any anticipated impact on its operating systems. The
1998 cost of the Year 2000 project for the core Intermedia business is estimated
to be $1.3 million in external personnel costs, and is being funded through
operating cash flows. This cost may be reduced if software and hardware are
replaced with compliant systems as a result of other capital projects currently
scheduled. The remaining expenses would not be expected to have a material
effect on the results of operations. Through year-end 1997, the Company has
incurred approximately $380,000 in expenses related to the assessment of, and
preliminary efforts on, its Year 2000 project and the development of plans for
systems modifications and testing. For the first quarter of 1998, the Company
has incurred approximately $250,000 on its ongoing Year 2000 project.

     Costs and timetables for Year 2000 projects associated with corporate
mergers and acquisitions are not included in the above estimates, and will be
funded on a case-by-case basis as they occur. During the first quarter of 1998
the Company has incurred approximately $25,000 related to systems review for two
of the Company's acquisitions. Assessments relating to additional costs to be
incurred for the Year 2000 project as it relates to the Company's acquisitions
is expected to be completed in the second quarter of 1998.

     The costs of the project and the date which the Company has established to
complete the Year 2000 modifications are based on management's best estimates,
which were derived utilizing numerous assumptions of future events, including
the continued availability of certain resources, third party modification plans
and other factors. However, there can be no guarantee that these estimates will
be achieved and actual results could differ materially from those anticipated.
Specific factors that might cause such material differences include, but are not
limited to, the availability and cost of personnel trained in this area, the
ability to locate and correct all relevant computer codes, unanticipated mergers
and acquisitions, and similar uncertainties.

Impact of Inflation

  Inflation has not had a significant impact on the Company's operations over
the past 3 years.


The information set forth above in "Management's Discussion and Analysis of
Financial Conditions and Results of Operations" include forward-looking
statements that involve numerous risks and uncertainties. The Company's actual
results could differ materially from those anticipated in such forward-looking
statements as a result of certain factors, including those set forth in the
section entitled "Risk Factors" in the Company's Annual Report on Form 10-K for
the year ended December 31, 1997.

approximately $137.2 million. The LDS Shares were issued by the Company to the
