INTERMEDIA COMMUNICATIONS INC.
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
         Company's Annual Report on Form 10-K for the year ended December 31,
         1996.

         Operating results for the three and nine month periods ended September
         30, 1997 are not necessarily an indication of the results that may be
         expected for the year ending December 31, 1997.

         Reclassification

         Certain prior year amounts have been reclassified to conform to the
         current year presentation.

         Recent Pronouncements

         Earnings per Share

         In February 1997, the Financial Accounting Standards Board issued
         Statement of Financial Accounting Standards No. 128, "Earnings Per
         Share" ("FASB 128"), which establishes standards for computing and
         presenting earnings per share. FASB 128 replaces the presentation of
         primary and fully diluted earnings per share with basic and diluted
         earnings per share, respectively. Basic earnings per share are computed
         by dividing income available to common stockholders by the weighted
         average number of common shares outstanding for the period. Diluted
         earnings per share are computed similarly to fully diluted earnings per
         share. The standard is effective for financial statements for periods
         ending after December 15, 1997, with earlier application not permitted.
         For the three and nine month periods ended September 30, 1997 and
         September 30, 1996, earnings per share, under FASB 128, would not have
         been impacted.

         Segments

         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" ("FASB 131"), which 
         supersedes Financial Accounting Standards No. 14. FASB 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. FASB 131 is effective for fiscal years beginning after 
         December 15, 1997.

         Comprehensive Income

         In June 1997, the Financial Accounting Standards Board issued Statement
         of Financial Accounting Standards No. 130, "Reporting Comprehensive
         Income" ("FASB 130"). FASB 130 requires that total comprehensive income
         and comprehensive income per share be disclosed with equal prominence
         as net income and earnings per share. Comprehensive income is defined
         as all changes in stockholders' equity exclusive of transactions with
         owners such as capital contributions and dividends. FASB 130 is
         effective for fiscal years beginning after December 15, 1997.

Note 2 Debt

         On July 9, 1997, concurrently with the sale of the 6,000,000 Series D
         Depositary Shares, (as defined in Note 3), the Company sold $606
         million principal amount at maturity of 11 1/4% Senior Discount Notes
         due 2007 (the "11 1/4% Notes") in a private placement transaction.
         Subsequent thereto, the over-allotment option with respect to the 11
         1/4% Notes was exercised and the Company sold an additional $43 million
         principal amount at maturity of 11 1/4% Notes. The issue price of the
         11 1/4% Notes was $577.48 per $1,000 principal amount at maturity of
         the 11 1/4% Notes. Net proceeds to the Company amounted to
         approximately $365 million. Cash interest will not accrue on the 11
         1/4% Notes prior to July 15, 2002. Commencing January 15, 2003, cash
         interest on the 11 1/4% Notes will be payable semi-annually in arrears
         on July 15 and January 15 at a rate of 11 1/4% per annum. The 11 1/4%
         Notes will be redeemable, at the Company's option at any time on or
         after July 15, 2002, and are pari passu with all other senior
         indebtedness.

         The Company used a portion of the proceeds of the 11 1/4% Notes to
         retire or defease (the"Retirement") Intermedia's outstanding 13 1/2%
         Senior Notes due 2005 (the "13 1/2% Notes"). The Retirement resulted in
         an extraordinary loss, as shown in the accompanying consolidated
         statement of operations, of approximately $44 million in the third
         quarter of 1997.

         Also see note 5, Subsequent Events, for information regarding an
         additional issuance of debt securities subsequent to September 30,
         1997.


Note 3 Preferred Stock

         On March 7, 1997, the Company sold 30,000 shares (aggregate liquidation
         preference $300 million) of its Series A Redeemable Exchangeable
         Preferred Stock, due 2009, (the "Series A Preferred Stock") in a
         private placement transaction. Net proceeds to the Company amounted to
         approximately $288 million. On June 6, 1997, the company issued 300,000
         shares (aggregate liquidation preference $300 million) of its 13 1/2%
         Series B Redeemable Exchangeable Preferred Stock due 2009 (the "Series
         B Preferred Stock"), which were registered under the Securities Act of
         1933, as amended, in exchange for all outstanding shares of the Series
         A Preferred Stock pursuant to a registered exchange offer. Dividends on
         the Series B Preferred Stock accumulate at a rate of 13 1/2% of the
         aggregate liquidation preference thereof and are payable quarterly, in
         arrears. Dividends are payable in cash or, at the Company's option, by
         the issuance of additional shares of Series B Preferred Stock having an
         aggregate liquidation preference equal to the amount of such dividends.
         The Series B Preferred Stock is subject to mandatory redemption at its
         liquidation preference of $1,000 per share, plus accumulated and unpaid
         dividends on March 31, 2009. The Series B Preferred Stock will be
         redeemable at the option of the Company at any time after March 31,
         2002 at rates commencing with 106.75%, declining to 100% on March 31,
         2007.

         The Company may, at its, option, exchange some or all shares of the
         Series B Preferred Stock for the Company's 13 1/2% Senior Subordinated
         Debentures, due 2009 (the "Exchange Debentures"). The Exchange
         Debentures mature on March 31, 2009. Interest on the Exchange
         Debentures is payable semi-annually, and may be paid in the form of
         additional Exchange Debentures at the Company's option. Exchange
         Debentures will be redeemable by the Company at any time after March
         31, 2002 at rates commencing with 106.75%, declining to 100% on March
         31, 2007.

         The Company is accreting the Series B Preferred Stock to its
         liquidation preference through the due date of the Series B Preferred
         Stock. The accretion for the three and nine month periods ended
         September 30, 1997 was $226 thousand and $512 thousand, respectively.

         The Company elected to issue approximately 13,000 additional shares of
         Series B Preferred Stock, in lieu of cash, with an aggregate
         liquidation preference of $12.9 million in June 1997, in payment of the
         first quarterly dividend (accumulated from March 7, 1997 through June
         30, 1997). In September 1997, the Company elected to issue
         approximately 11,000 additional shares of Series B Preferred Stock, in
         lieu of cash, with an aggregate liquidation preference of $10.6
         million, in payment of the second quarterly dividend (accumulated from
         July 1, 1997 through September 30, 1997).



                                       7
<PAGE>   8

         On July 9, 1997, the Company sold 6,000,000 Depositary Shares (the
         "Series D Depositary Shares") (aggregate liquidation preference
         $150,000,000) each representing a one-hundredth interest in a share of
         the Company's 7% Series D Junior Convertible Preferred Stock, (the
         "Series D Preferred Stock"), in a private placement transaction.
         Subsequent thereto, the over-allotment option with respect to the
         Series D Depositary Shares was exercised and the Company sold an
         additional 900,000 Series D Depositary Shares (aggregate liquidation
         preference of $22,500,000). Net proceeds to the Company amounted to
         approximately $167 million. Dividends on the Series D Preferred Stock
         will accumulate at a rate of 7% of the aggregate liquidation preference
         thereof and are payable quarterly, in arrears. Dividends are payable in
         cash or, at the Company's option, by the issuance of shares of Common
         Stock of the Company. The Series D Preferred Stock will be redeemable
         at the option of the Company at any time on or after July 19, 2000 at
         rates commencing with 104%, declining to 100% on July 19, 2004.

         The Series D Preferred Stock is convertible, at the option of the
         holder, into Common Stock of the Company at a conversion price of
         $38.90 per share of Common Stock, subject to certain adjustments.

         The Company is accreting the Series D Depositary Shares to its
         liquidation preference through the due date of the Series D Preferred
         Stock. The accretion for the three and nine month periods ended
         September 30, 1997 was $357 thousand.

         Also see note 5, Subsequent Events, for information regarding an
         additional issuance of preferred stock subsequent to September 30,
         1997.

Note 4 Acquisitions

         During June 1996, the Company acquired the Telecommunications Division
         of EMI Communications corporation ("EMI") in exchange for 937,500
         shares of the Company's Common stock, valued at approximately $16.9
         million. The acquisition was accounted for by the purchase method of
         accounting, with the purchase price allocated to the fair values of
         assets acquired, principally telecommunications equipment. EMI's
         telecommunications division, headquartered in Syracuse, New York, is a
         provider of frame relay based network services and interexchange
         private line services primarily in the northeastern United States. EMI
         operates owned and leased microwave and fiber optic digital network
         capacity in New York, Massachusetts, Vermont, Rhode Island,
         Connecticut, New Jersey, Pennsylvania, Maryland and the District of
         Columbia and maintains POPs in most major cities in these states.

         During December 1996, the Company acquired, in two separate
         transactions, certain assets and the related businesses of Universal
         Telcom, Inc. ("UTT") and NetSolve, Incorporated ("NetSolve"). The
         purchase price for UTT included 31,380 shares of the Company's common
         stock, valued at approximately $.9 million, and the assumption of
         approximately $2 million of UTT's liabilities. NetSolve was purchased
         for cash of $12.8 million. The acquisitions are accounted for by the
         purchase method of accounting, with the purchase price allocated to the
         fair value of assets acquired, principally goodwill. The goodwill,
         including an additional $.2 million for legal expenses, for these
         acquisitions has been adjusted during the first quarter of 1997 due to
         the finalization of the purchase price allocation.

         On June 24, 1997, the Company purchased from Telco Communications
         Group, Inc. ("Telco") five long distance voice switches and ancillary
         network equipment located in Atlanta, Chicago, Dallas, Los Angeles and
         New York (the "Telco Acquisition"). Three of these switches will be
         upgraded to local/long distance voice switches, consistent with the
         Company's planned deployment of at least fifteen local/long distance 
         voice switches by the end of 1997. As part of the Telco Acquisition, 
         the Company also acquired certain network transport services for a 
         three year period. The aggregate purchase price of the Telco 
         Acquisition was approximately $38 million. The company believes that 
         the Telco Acquisition will allow the Company to more rapidly deploy 
         local/long distance voice switches in these markets and to do so at a 
         lower overall cost. In addition, the transport services acquired as 
         part of the Telco Acquisition will permit the Company to accelerate its
         deployment of ATM in its intercity and intracity networks.
         Implementation of ATM will facilitate additional enhanced data and
         voice services and network efficiencies.

<PAGE>   9

         During July 1997, Intermedia acquired DIGEX, Incorporated ("DIGEX"), a
         leading nationwide business Internet services provider. Aggregate cash
         consideration for the acquisition was approximately $155 million and
         was funded with the Company's existing cash reserves. 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. For purpose of the financial statements as of
         September 30, 1997 and for the periods then ended, certain aspects of
         the purchase price allocation, related to duplicate network facilities
         and differing lease market rates, were accounted for on a preliminary
         basis pending the receipt by the Company of additional information and
         the performance of certain evaluations. Such information and
         evaluations are anticipated to be completed in the fourth quarter. In
         addition, the Company obtained an independent valuation related to
         fixed assets, developed and in-process technology, and other
         identifiable intangible assets. Based upon this valuation, the amount
         allocated to purchased research and development ($60 million) is
         recorded as a one-time charge to earnings in the accompanying
         consolidated statements of operations.

         The following unaudited pro forma results of operations presents the
         consolidated results of operations as if the acquisition of UTT,
         NetSolve and EMI had occurred on January 1, 1996, and DIGEX on January
         1, 1997. These proforma results do not purport to be indicative of the
         results that actually would have occurred if the companies had been
         acquired as of that date or of results which may occur in the future.

Note 5 Subsequent Events

         On October 30, 1997, the Company sold 7,000,000 Depositary Shares (the
"Series E Depositary Shares") (aggregate liquidation preference $175,000,000)
each representing a one-hundredth interest in a share of the Company's 7% Series
E Junior Convertible Preferred Stock, (the "Series E Preferred Stock"), in a
private placement transaction. Subsequent thereto, the over-allotment option
with respect to the Series E Depositary Shares was exercised and the Company
sold an additional 1,000,000 Series E Depositary Shares (aggregate liquidation
preference of $25,000,0000). Net proceeds to the Company amounted to
approximately $193.8 million. Dividends on the Series E Preferred Stock will
accumulate at a rate of 7% of the aggregate liquidation preference thereof and
are payable quarterly, in arrears. Dividends are payable in cash or, at the
Company's option, by the issuance of shares of Common Stock of the Company. The
Series E Preferred Stock will be redeemable at the option of the Company at any
time on or after October 18, 2000 at rates commencing with 104%, declining to
100% on October 18, 2004.

         The Series E Depositary Shares will be convertible at any time after
December 29, 1997, at the option of the holder into Common Stock of the Company
at a conversion price of $60.47 per share of Common Stock, subject to certain
adjustments.

         Concurrently with the sale of the Series E Depositary Shares, the
Company sold $250 million principal amount of 8 7/8% Senior Notes due 2007 (the
"8 7/8% Notes") in a private placement transaction. Net proceeds to the Company
amounted to approximately $243 million. Cash interest on the 8 7/8% Notes will
be payable semi-annually in arrears on May 1 and November 1 at a rate of 8 7/8%
per annum. The 8 7/8% Notes will be redeemable, at the Company's option at any
time on or after November 1, 2002, and are pari passu with all other senior
indebtedness.

         The proceeds of the Series E Depositary Shares will be used to finance
the continued expansion of the Company's telecommunications networks, including
but not limited to, network electronics, such as local/long distance voice and
data switches, and for general corporate purposes, including working capital.
The net proceeds from the offering of the 8 7/8% Notes will be used to fund up
to 80% of the cost of acquisition or construction by the Company of
telecommunications-related assets.

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, 1996 filed with the Securities and Exchange
Commission.

OVERVIEW
         Intermedia Communications Inc. ("Intermedia" or the "Company"),
formerly Intermedia Communications of Florida, Inc. through May 29, 1996, is a
rapidly growing provider of integrated telecommunications solutions for
business, government, and the telecommunications industry. Headquartered in
Tampa, Florida, Intermedia is the third largest (based on annualized
telecommunications revenues) among providers referred to as Competitive Local
Exchange Carriers ("CLECs"). Intermedia offers a full suite of local,
long-distance and enhanced data telecommunications services to business and
government end user customers, long distance carriers, Internet service
providers, resellers, and wireless communications companies serving customers
from 43 sales offices located throughout the eastern United States. Intermedia
also provides enhanced data/ATM and Internet services in approximately 3,787
cities nationwide, offering customers seamless end-to-end connectivity virtually
anywhere in the world.

         Since its inception in 1987, the Company has experienced substantial
growth. Building from its original base in Florida, Intermedia is now a provider
of integrated telecommunications services to customers that have a presence in
the eastern United States. The Company currently has ten digital fiber optic
networks and provides end-to-end connectivity throughout the United States and
many international markets. As its networks and service offerings have expanded,
the Company has experienced significant year to year growth in revenues and
customers.

         Intermedia competes with the Incumbent Local Exchange Carriers
("ILECs") and Interexchange Carriers ("IXCs") in its service territory and
offers a full range of voice and data telecommunications services. Intermedia's
customers include a broad range of business and government end users and IXC's.
The Company delivers local network services, including local exchange service,
primarily over digital fiber optic telecommunications networks that it either
owns or leases. In some circumstances, 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 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. This intercity network
combined with the Company's local/long distance voice switches allows the
Company to provide interexchange long distance service domestically and
internationally.

         At its inception, Intermedia provided special access and private line
services to IXC's. 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 integration services in
response to customer's needs and in 1992, Intermedia introduced its first
enhanced data services to provide flexible capacity and highly reliable
end-to-end data service for its business and government customers. The Company
began offering interexchange long distance service in December 1994, Internet
services in 1995 and local exchange services in 1996. The pace with which the
Company has introduced new service offerings has enabled it to achieve
substantial growth, improve its mix 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 over the next several
years, 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, the IXC's may enter the
market by becoming resellers of the Company's local services. If the IXC's
pursue a reseller strategy, the amount of revenue the Company realizes from
carriers may increase during this period.

         From 1992 through 1995, the Company had achieved positive EBITDA and
increased its revenue base substantially. However, as a result of significant
investments in resources necessary to launch local exchange services and expand
enhanced data services, EBITDA decreased as a percentage of revenue and the
Company's EBITDA was negative for 1996 and the first three quarters of 1997.
This was due to the significant up front expenses related to the development of
its networks and leased facilities, the revenue from which is expected to be



                                       10
<PAGE>   11

realized in later periods. The development of the Company's business and the
installation and expansion of its networks have resulted in substantial capital
expenditures and net losses during this period of its operations. Procurement of
rights-of-way, 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 during its rapid
expansion. 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 expected to generate
recurring revenue for the Company for several years. The continued expansion of
the Company's networks in anticipation of 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, but there can be no
assurance, that as its customer base grows, incremental revenues will be greater
than incremental operating expenses.

         On June 24, 1997, the Company purchased from Telco Communications
Group, Inc. ("Telco") five long distance voice switches and ancillary network
equipment located in Atlanta, Chicago, Dallas, Los Angeles and New York (the
"Telco Acquisition"). Three of these switches will be upgraded to local/long
distance voice switches, consistent with the Company's planned deployment of at
least fifteen local/long distance voice switches by the end of 1997. As part of
the Telco Acquisition, the Company also acquired certain network transport 
services for a three year period. The aggregate purchase price of the Telco 
Acquisition was approximately $38 million, which was substantially included in 
the Company's planned expenditures for 1997. The company believes that the 
Telco Acquisition will allow the Company to more rapidly deploy local/long 
distance voice switches in these markets and to do so at a lower overall cost.
In addition, the transport services acquired as part of the Telco Acquisition 
will permit the Company to accelerate its deployment of ATM in its intercity 
and intracity networks. Implementation of ATM will facilitate additional 
enhanced data and voice services and network efficiencies.

         On July 11, 1997, Intermedia's wholly owned subsidiary, Daylight
Acquisition Corp., completed a merger (the "Merger") with DIGEX, Incorporated
("DIGEX"), a leading nationwide business Internet services provider. The
aggregate cash consideration for the acquisition was approximately $155 million
and was funded with the Company's existing cash reserves in July 1997.

         During the remainder of 1997 and beyond, 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 $25 billion in 1996 in the
Company's service territory. As a result of the Company's planned expansion in
1997, the Company expects to be positioned to provide these services in markets
with a total opportunity of approximately $34 billion by the end of 1997,
exclusive of the opportunities provided by the DIGEX acquisition.

         In order to develop its business more rapidly and efficiently utilize
its capital resources, Intermedia plans to use the existing fiber optic
infrastructure of other providers in addition to using its existing networks.
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 that its substantial existing network capacity should enable it to add
new customers and provide additional services that will result in increased
revenues with lower incremental costs and, correspondingly, over time 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 SEPTEMBER 30, 1997 COMPARED TO QUARTER ENDED SEPTEMBER 30, 1996

         Revenue

         Total revenue increased 109.7% to $71.3 million for the third quarter
of 1997 compared to $34.0 million for the same period in 1996. This increase
primarily resulted from the acquisition of DIGEX, 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. A portion of the
increase was attributable to the inclusion of DIGEX's operating results for the
third quarter of 1997.

         Local network services revenue increased 259.3% to $11.8 million for
the third quarter of 1997 compared to $3.2 million for the same period in 1996.
This increase primarily resulted from the continued rollout of local exchange
services into additional markets. The Company has received CLEC certification in
28 states plus the District of Columbia as of the end of the third quarter of
1997.

         Enhanced data services revenue increased 187.0% to $30.8 million for
the third quarter of 1997 compared to $10.7 million for the same period in 1996.
This increase primarily resulted from the expansion of the Company's enhanced
data network by 54 switches and 8,824 new frame relay nodes since July 1, 1996.
In addition, the number of frame relay cities has increased by 2,653 during the
same time period. Of the revenue increase, a significant portion was
attributable to the inclusion of DIGEX's operating results for the third quarter
of 1997.

         Interexchange services revenue increased 43.6% to $27.6 million for the
third quarter of 1997 compared to $19.2 million for the same period in 1996.
This increase primarily resulted from strong growth in long distance switched
revenue and steady growth in interLATA transport.

         Integration services revenue increased 36.6% to $1.0 million for the
third quarter of 1997 compared to $.7 million for the same period in 1996. This
increase primarily resulted from the Company's increased focus on providing a
total service package for the customer.

         Operating Expenses

         Total operating expenses increased 269.8% to $160.6 million for the
third quarter of 1997 compared to $43.4 million for the same period in 1996. The
increase primarily resulted from the costs associated with the significant
expansion of the Company's owned and leased networks and the continued expansion
in personnel to sustain and support the Company's growth. Of the increase,
approximately $60 million resulted from the charge for in-process research and
development and the inclusion of DIGEX's operating results for the third 
quarter of 1997.

         Network operations expenses increased 96.1% to $49.0 million for the
third quarter of 1997 compared to $25.0 million for the same period in 1996.
This increase primarily resulted from the increases in leased network capacity
that is associated with the growth of local network service, enhanced data
service and interexchange service revenues. A portion of the increase was 
attributable to the inclusion of DIGEX's operating results for the third 
quarter of 1997.

         Facilities administration and maintenance expenses increased 313.8% to
$10.0 million for the third quarter of 1997 compared to $2.4 million for the
same period in 1996. A portion of the increase was attributable to the 
inclusion of DIGEX's operating results for the third quarter of 1997. 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.

         Selling, general and administrative expenses increased 145.8% to $25.0
million for the third quarter of 1997 compared to $10.2 million for the same
period in 1996. This increase primarily resulted from the Company's continued
growth and represented a major 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. A portion of the increase was 
attributable to the inclusion of DIGEX's operating results for the third 
quarter of 1997.

         Depreciation and amortization expenses increased 206.4% to $16.1
million for the third quarter of 1997 compared to $5.3 million for the same
period in 1996. This increase primarily resulted from additions to
telecommunications equipment placed in service during 1996 and the first nine
months of 1997, relating to ongoing network expansion. A portion of the 
increase was attributable to the inclusion of DIGEX's operating results for the
third quarter of 1997.

         Charge for in-process Research & Development of $60 million represents
the amount of the purchased in-process research and development associated with
the purchase of DIGEX. This cost is recorded as a one-time charge to earnings in
the third quarter of 1997.

         Interest Expense

         Interest expense increased 64.2% to $17.7 million for the third quarter
of 1997 compared to $10.8 million for the same period in 1996. This increase
primarily resulted from interest expense on the May 1996 issuance of $330
million principal amount at maturity of the Company's 12 1/2% Senior Discount
Notes due 2006 (the "12 1/2% Notes") and the July 1997 issuance of $649 million,
including the over-allotment option, principal amount at maturity of the
Company's 11 1/4% Notes.

         Other Income

         Other income increased 17.7% to $6.7 million for the third quarter of
1997 compared to $5.7 million for the same period in 1996. This increase was
primarily the result of interest earned on the cash available from the excess
proceeds relating to the May 1996 issuance of the 12 1/2% Notes, the May 1996
issuance of 4,674,503 common shares, par value $.01 per share, at $26.00 per
share, the March 1997 issuance of 30,000 shares of the Company's Series A
Preferred Stock, which was subsequently exchanged for the Series B Preferred
Stock, the July 1997 issuance of the 11 1/4% Notes and the July 1997 issuance of
6,900,000 Series D Depositary Shares.

         Extraordinary Loss of $43.8 million for the third quarter of 1997
consisted of pre-payment penalties relating to certain indebtedness which was
repaid from the proceeds of the offering of the 11 1/4% Notes and the write-off
of the unamortized deferred financing costs associated with the indebtedness
repaid.

         Net Loss

         Net loss increased 893.8% to $144.2 million for the third quarter of
1997 compared to $14.5 million for the same period in 1996. This increase was
due primarily to the increased operating expenses resulting from the expansion
of the network, increased selling general and administrative costs, the charge
for in-process research & development, increased interest costs and the
extraordinary items.

         Preferred Stock Dividends and Accretions

         Preferred stock dividends and accretions of $13.9 million resulted from
the March 1997 issuance of 30,000 shares of the Company's Series A Preferred
Stock, which was subsequently exchanged for the Series B Preferred Stock, and
the July 1997 issuance of 6,900,000 Series D Depositary Shares.

         EBITDA

         EBITDA decreased 216.2% to $(13.3) million for the third quarter of
1997 compared to $(4.2) million for the same period in 1996. This decline was
the result of the acceleration in the deployment of Intermedia's capital
expansion plan which significantly increased growth oriented expenses, such as
network expenses, increases in sales, customer service and market development 
costs, prior to realizing revenues associated with these expenditures.

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 $179 million and $81 million for the nine months ended September 30, 1997
and 1996, respectively. 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)
development of the Company's enhanced data services. In addition, the Company
utilized approximately $155 million of its available cash to complete the
acquisition of DIGEX in July 1997.

         The Company has funded a substantial portion of these expenditures
through the public sale of debt and equity securities and to a lesser extent,
privately placed debt. From inception through December 31, 1996, the Company
raised approximately $212.6 million from the sale of Common Stock, including
Common Stock issued in connection with the acquisitions of FiberNet, Phone One,
EMI and UTT, and $324.6 million from the sale of senior debt.

         The substantial capital investment required to build the Company's
network has resulted in negative cash flow from operations after consideration
of investing activities over the last five year period. This negative cash flow
after investing activities was 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 expansion activities associated with the development of the Company's
networks. Until sufficient cash flow after investing activities is generated
from operations, the Company will be required to utilize its 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 spending necessary to more rapidly
exploit the market opportunity in the local exchange market. The Company expects
to expend substantial amounts to upgrade its existing networks in order to
switch traffic within the local service area in those states where it is
currently permitted to provide such services. The Company is certified as a CLEC
in 28 states and the District of Columbia, allowing the Company to provide local
exchange services in those markets. In addition, the Company expects to expend
capital toward the further development of the Company's enhanced data service
and interchange service offerings.

         The Company currently estimates that it will require approximately $45
million to fund anticipated capital requirements during the remainder of 1997,
which it expects to fund from its available cash. The Company does not believe
that the acquisition of DIGEX will have a material impact on its capital
expenditure requirements.

         On March 7, 1997, the Company sold 30,000 shares (aggregate liquidation
preference $300,000,000) of Series A Preferred Stock in a private placement
transaction. Net proceeds to the Company amounted to approximately $288 million.
On June 6, 1997, the company issued 300,000 shares (aggregate liquidation
preference $300 million) of its Series B Preferred Stock, which were registered
under the Securities Act of 1933, as amended, in exchange for all outstanding
shares of the Series A Preferred Stock pursuant to a registered exchange offer.
Dividends on the Series B Preferred Stock accumulate at a rate of 13 1/2% of the
aggregate liquidation preference thereof and are payable quarterly, in arrears.
Dividends are payable in cash or, at the Company's option, by the issuance of
additional shares of Series B Preferred Stock having an aggregate liquidation
preference equal to the amount of such dividends. The Series B Preferred Stock
is subject to mandatory redemption at its liquidation preference of $1,000 per
share, plus accumulated and unpaid dividends on March 31, 2009. The Series B
Preferred Stock will be redeemable at the option of the Company at any time
after March 31, 2002 at rates commencing with 106.75%, declining to 100% on
March 31, 2007.

         The Company may, at its, option, exchange some or all shares of the
Series B Preferred Stock for the Company's Exchange Debentures. The Exchange
Debentures mature on March 31, 2009. Interest on the Exchange Debentures is
payable semi-annually, and may be paid in the form of additional Exchange
Debentures at the 



                                       17
<PAGE>   18

Company's option. Exchange Debentures will be redeemable by the Company at any
time after March 31, 2002 at rates commencing with 106.75%, declining to 100% on
March 31, 2007.

         On July 11, 1997, Intermedia's wholly owned subsidiary, Daylight
Acquisition Corp., completed a merger with DIGEX, a leading nationwide business
Internet services provider. The aggregate cash consideration for the acquisition
was approximately $155 million and was funded with the Company's existing cash
reserves in July 1997.

         On July 9, 1997, the Company sold 6,000,000 Series D Depositary Shares
(aggregate liquidation preference $150,000,000) each representing a
one-hundredth interest in a share of the Company's Series D Preferred Stock, in
a private placement transaction. Subsequent thereto, the over-allotment option
with respect to the Series D Depositary Shares was exercised and the Company
sold an additional 900,000 Series D Depositary Shares (aggregate liquidation
preference of $22,500,000). Net proceeds to the Company amounted to
approximately $167 million. Dividends on the Series D Preferred Stock will
accumulate at a rate of 7% of the aggregate liquidation preference thereof and
are payable quarterly, in arrears. Dividends are payable in cash or, at the
Company's option, by the issuance of shares of Common Stock of the Company. The
Series D Preferred Stock will be redeemable at the option of the Company at any
time on or after July 19, 2000 at rates commencing with 104%, declining to 100%
on July 19, 2004.

         The Series D Preferred Stock is convertible, at the option of the
holder, into Common Stock of the Company at a conversion price of $38.90 per
share of Common Stock, subject to certain adjustments.

         Concurrently with the sale of the Series D Depositary Shares, the
Company sold $606 million principal amount at maturity of 11 1/4% Notes in a
private placement transaction. Subsequent thereto, the over-allotment option
with respect to the 11 1/4% Notes was exercised and the Company sold an
additional $43 million principal amount at maturity of 11 1/4% Notes. The issue
price of the 11 1/4% Notes was $577.48 per $1,000 principal amount at maturity
of the 11 1/4% Notes. Net proceeds to the Company amounted to approximately $365
million. Cash interest will not accrue on the 11 1/4% Notes prior to July 15,
2002. Commencing January 15, 2003, cash interest on the 11 1/4% Notes will be
payable semi-annually in arrears on July 15 and January 15 at a rate of 11 1/4%
per annum. The 11 1/4% Notes will be redeemable, at the Company's option at any
time on or after July 15, 2002, and are pari passu with all other senior
indebtedness.

         The Company used a portion of the proceeds of the private offering of
the 11 1/4% Notes to retire or defease Intermedia's outstanding 13 1/2% Notes.
The Retirement resulted in an extraordinary loss, as shown in the accompanying
consolidated statement of operations, of approximately $44 million in the third
quarter of 1997.

         On October 30, 1997, the Company sold 7,000,000 Series E Depositary
Shares (aggregate liquidation preference $175,000,000) each representing a
one-hundredth interest in a share of the Company's Series E Preferred Stock, in
a private placement transaction. Subsequent thereto, the over-allotment option
with respect to the Series E Depositary Shares was exercised and the Company
sold an additional 1,000,000 Series E Depositary Shares (aggregate liquidation
preference of $25,000,0000). Net proceeds to the Company amounted to
approximately $193.8 million. Dividends on the Series E Preferred Stock will
accumulate at a rate of 7% of the aggregate liquidation preference thereof and
are payable quarterly, in arrears. Dividends are payable in cash or, at the
Company's option, by the issuance of shares of Common Stock of the Company. The
Series E Preferred Stock will be redeemable at the option of the Company at any
time on or after October 18, 2000 at rates commencing with 104%, declining to
100% on October 18, 2004.

         The Series E Preferred Stock will be convertible at any time after
December 29, 1997, at the option of the holder into Common Stock of the Company
at a conversion price of $60.47 per share of Common Stock, subject to certain
adjustments.

         Concurrently with the sale of the Series E Depositary Shares, the
Company sold $250 million principal amount at maturity of 8 7/8% Notes due in a
private placement transaction. Net proceeds to the Company amounted to
approximately $243 million. Cash interest on the 8 7/8% Notes will be payable
semi-annually in arrears on May 1 and November 1 at a rate of 8 7/8% per annum.
The 8 7/8% Notes will be redeemable, at the Company's option at any time on or
after November 1, 2002, and are pari passu with all other senior indebtedness.



                                       18
<PAGE>   19

         The proceeds from the Series E Depositary Shares will be used to
finance the continued expansion of the Company's telecommunications networks,
including but not limited to, network electronics, such as local/long distance
voice and data switches, and for general corporate purposes, including working
capital. The net proceeds from the offering of the 8 7/8% Notes will be used to
fund up to 80% of the cost of acquisition or construction by the Company of
telecommunications-related assets.

         The Company expects that its available cash, including proceeds from
the concurrent offerings of the 8 7/8% Notes and Series E Depositary Shares, and
credit availability will be sufficient to fund its current accelerated and
expanded capital deployment plan. If the Company were to require additional
financing, it would seek to obtain such financing through the sale of public or
private debt and/or equity securities or through securing a bank credit
facility. There can be no assurance as to the availability of the terms upon
which such financing might be available. Moreover, the 12 1/2% Notes, the 11
1/4% Notes, the 8 7/8% Notes and the Series B Preferred Stock impose certain
restrictions upon the Company's ability to incur additional indebtedness or
issue additional preferred stock.

         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 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 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" includes forward-looking

PART II. OTHER INFORMATION

ITEM 1.  Legal Proceedings

         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 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 preliminary and permanent injunction enjoining the Merger
but no applications were made for such injunctions prior to consummation of the
Merger on July 11, 1997. In addition, the Complaints seek cash damages from the
DIGEX Directors. In August 1997, a motion to dismiss the Complaints was filed
on behalf of Intermedia, DIGEX and the DIGEX Directors.

         These cases are in their very 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.

ITEM 2.  Changes in Securities

         On July 9, 1997, the Company sold 6,000,000 Series D Depositary Shares
(aggregate liquidation preference $150,000,000) each representing a
one-hundredth interest in a share of the Company's Series D Preferred Stock, in
a private placement transaction. Subsequent thereto, the over-allotment option
with respect to the Series D Depositary Shares was exercised and the Company
sold an additional 900,000 Series D Depositary Shares (aggregate liquidation
preference of $22,500,000). Net proceeds to the Company amounted to
approximately $167 million. Dividends on the Series D Preferred Stock will
accumulate at a rate of 7% of the aggregate liquidation preference thereof and
are payable quarterly, in arrears. Dividends are payable in cash or, at the
Company's option, by the issuance of shares of Common Stock of the Company. The
Series D Preferred Stock will be redeemable at the option of the Company at any
time on or after July 19, 2000 at rates commencing with 104%, declining to 100%
on July 19, 2004.

         The Series D Preferred Stock is convertible, at the option of the
holder, into Common Stock of the Company at a conversion price of $38.90 per
share of Common Stock, subject to certain adjustments.

         The Series D Depositary Shares were issued and sold to the initial
purchasers pursuant to an exemption from registration provided by Section 4(2)
of the Securities Act of 1933, as amended (the "Act"). Each of the initial
purchasers of the Series D Depositary Shares represented to the Company, among
other things, that (i) it is a qualified institutional buyer ("QIB"), (ii) it is
not acquiring the Series D Depositary Shares with a view to any distribution
thereof that would violate the Act or the securities laws of any state of the
United States or any other applicable jurisdiction, (iii) it will be re-offering
and reselling the Series D Depositary Shares only to QIBs in reliance on the
exemption from the registration requirements of the Act provided by Rule 144A
and to accredited investors in a private placement exempt from the registration
requirements of the Act, and (iv) no form of general solicitation or general
advertising has been or will be used by it or any of its representatives in
connection with the offer and sale of any of the Depositary Shares.

         On October 30, 1997, the Company sold 7,000,000 Series E Depositary
Shares (aggregate liquidation preference $175,000,000) each representing a
one-hundredth interest in a share of the Company's Series E Preferred Stock, in
a private placement transaction. Subsequent thereto, the over-allotment option
with respect to the Series E Depositary Shares was exercised and the Company
sold an additional 1,000,000 Series E Depositary Shares (aggregate liquidation
preference of $25,000,0000). Net proceeds to the Company amounted to
approximately $193.8 million. Dividends on the Series E Preferred Stock will
accumulate at a rate of 7% of the aggregate liquidation preference thereof and
are payable quarterly, in arrears. Dividends are payable in cash or, at the
Company's option, by the issuance of shares of Common Stock of the Company. The
Series E Preferred Stock will be redeemable at the option of the Company at any
time on or after October 18, 2000 at rates commencing with 104%, declining to
100% on October 18, 2004.

         The Series E Preferred Stock will be convertible at any time after
December 29, 1997, at the option of the holder, into Common Stock of the Company
at a conversion price of $60.47 per share of Common Stock, subject to certain
adjustments.

         The Series E Depositary Shares were issued and sold to the initial
purchasers pursuant to an exemption from registration provided by Section 4(2)
of the Securities Act of 1933, as amended (the "Act"). Each of the initial
purchasers of the Series E Depositary Shares represented to the Company, among

thereof that would violate the Act or the securities laws of any state of the
United States or any other applicable jurisdiction, (iii) it will be re-offering
and reselling the Series E Depositary Shares only to QIBs in reliance on the
exemption from the registration requirements of the Act provided by Rule 144A,
pursuant to offers and sales that occur outside the United States within the
meaning of Regulation S, and to accredited investors in a private placement
exempt from the registration requirements of the Act, and (iv) no form of
general solicitation or general advertising has been or will be used by it or
any of its representatives in connection with the offer and sale of any of the
Series E Depositary Shares.
