              ADELPHIA COMMUNICATIONS CORPORATION AND SUBSIDIARIES
        NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)
                (Dollars in thousands, except per share amounts)


         The accompanying unaudited condensed consolidated financial statements
of Adelphia Communications Corporation and its majority owned subsidiaries
("Adelphia" or the "Company") have been prepared in accordance with the rules
and regulations of the Securities and Exchange Commission.

         In the opinion of management, all adjustments, consisting of only
normal recurring accruals necessary for a fair presentation of the financial
position of Adelphia at June 30, 1998, and the results of operations for the
three months ended June 30, 1997 and 1998, have been included. These condensed
consolidated financial statements should be read in conjunction with Adelphia's
consolidated financial statements included in its Annual Report on Form 10-K for
the fiscal year ended March 31, 1998 ("Annual Report"). The results of
operations for the three months ended June 30, 1998 are not necessarily
indicative of the results to be expected for the year ending March 31, 1999.

1.    Significant Events Subsequent to the Annual Report:

         On April 1, 1998, the Company completed an exchange of cable systems
with Time Warner. The Company exchanged its interests in Mansfield, Ohio area
systems, which served approximately 64,400 subscribers, and approximately
$11,000 cash for interests in systems adjacent to systems owned or managed by
Adelphia in Virginia, New England and New York, which served approximately
70,200 subscribers. No gain or loss was recognized in connection with this
transaction.

         On May 8, 1998, Hyperion Telecommunications, Inc. ("Hyperion")
completed an initial public offering ("IPO") of its Class A Common Stock
("Hyperion Stock"). As part of the offering, Adelphia purchased an incremental
3,324,001 shares of Hyperion Stock for $49,900 and converted indebtedness owed
to the Company by Hyperion into 3,642,666 shares of Hyperion Stock. In addition,
Adelphia purchased warrants issued by Hyperion to MCI Metro Access Transmission
Services, Inc., and purchased shares of Hyperion Class B common stock from
certain executive officers of Hyperion for a total purchase price of
approximately $12,580 and $3,000, respectively. Adelphia owns approximately 66% 
of the Hyperion common stock on a fully diluted basis and 85% of the total
voting power. Additional net proceeds of $191,685 to Hyperion were received as a
result of the sale of Hyperion Stock to the public. As a result of the IPO,
Adelphia's additional paid-in capital increased approximately $147,000 and
minority interests increased approximately $45,000.

         On May 15, 1998, Adelphia redeemed $69,838 aggregate principal amount
of 12 1/2% Senior Notes due 2002 at 103% of principal. As a result of this
transaction, Adelphia recognized an extraordinary loss of $2,604.

         On June 5, 1998, Adelphia acquired cable systems from Cablevision
Systems. These systems served approximately 11,250 subscribers at the date of
acquisition in southern New York and were purchased for an aggregate price of
$11,500. The acquisition was accounted for under the purchase method of
accounting. Accordingly, the financial results of the acquired systems are
included in the consolidated results of Adelphia effective with the date
acquired.

         Since April 1, 1998, Hyperion entered into a series of agreements, 
totaling $107,000 with Qwest Communications, Williams Communications and several
other fiber optic network providers. These agreements will provide Hyperion with
ownership or an indefeasible right of use to over 8,100 route miles of fiber 
optic cable, which will significantly increase its presence in the eastern half 
of the United States.

         On July 2, 1998, Adelphia issued $150,000 of 8 1/8% Senior Notes due
2003 (the "Senior Notes"). Net proceeds of approximately $147,300, after payment
of transaction costs, were used to repay debt of subsidiaries. The terms of the
Senior Notes are similar to those of Adelphia's existing publicly held senior
debt.

         On August 3, 1998, Adelphia announced that it closed its transaction
with Tele-Communications, Inc.("TCI") to form a joint venture limited
partnership in the Western New York region. Pursuant to this agreement, Adelphia
contributed its Western New York and Lorain, Ohio systems, totaling
approximately 298,000 subscribers and certain programming assets and $440,000 in
debt. Subsidiaries of TCI contributed their cable systems in Buffalo, New York;
Erie, Pennsylvania; and Ashtabula and Lake County, Ohio, totaling approximately
171,000 subscribers and $228,000 in debt. Adelphia and TCI hold a 66.7% and
33.3% interest, respectively, in the partnership. Adelphia will manage the
partnership and will consolidate the partnership's results of operations for
financial reporting purposes beginning on the acquisition date.  As part of this
transaction, the joint venture became a party to one of Adelphia's subsidiaries'
revolving credit facilities and repaid the TCI contributed debt with the 
borrowings under that revolving credit facility.

         On August 13, 1998, Adelphia announced agreements with several
underwriters and the Rigas family to sell 8,190,315 shares of its Class A Common
Stock. Of this total, 4,100,000 shares will be sold to the public at a price of
$32.00 per share, with an underwriting discount of $1.44 per share. The
remaining 4,090,315 shares will be sold to entities controlled by the Rigas
Family at the public offering price less the underwriting discount. Net proceeds
to Adelphia after offering expenses are expected to be approximately $250,000.
The sale of stock is expected to be consummated on August 18, 1998.

2.  Debt:

         Debt is summarized as follows:

         The investment in Olympus represents a 50% voting interest in such
partnership and is being accounted for using the equity method. Summarized
unaudited results of operations of Olympus are as follows:


                                         Six Months Ended

Net loss of general partners
 after priority return                  (46,410)        (51,623)


5. Net Loss Per Weighted Average Share of Common Stock:

         Basic net loss per weighted average share of common stock is computed
based on the weighted average number of common shares outstanding after giving
effect to dividend requirements on the Company's preferred stock. Diluted net
loss per common share is equal to basic net loss per common share because the
Company's Convertible Preferred Stock had an antidilutive effect for the periods
presented; however, the Convertible Preferred Stock could have a dilutive effect
on earnings per share in future periods.

6. Supplemental Financial Information:

         Cash payments for interest were $44,212 and $35,262 for the three
months ended June 30, 1997 and 1998, respectively. Accumulated depreciation of
property, plant and equipment amounted to $649,527 and $675,798 at March 31,
1998 and June 30, 1998, respectively. Accumulated amortization of intangible
assets amounted to $211,967 and $221,203 at March 31, 1998 and June 30, 1998,
respectively. Interest expense - net includes interest income of $2,444 and
$8,080 for the three months ended June 30, 1997 and 1998, respectively. Interest
income includes interest income from affiliates on long term loans and for
reimbursement of interest expense on revolving credit agreements related to
short term borrowings by such affiliates.

7. Income Taxes:

         Income tax benefit for the three months ended June 30, 1998 was $5,614,
which is substantially comprised of a deferred tax benefit.

8. Recent Accounting Pronouncements:

         Statement of Financial Accounting Standards ("SFAS") No. 130,
"Reporting Comprehensive Income," issued by the Financial Accounting Standards
Board in June 1997 is effective for the interim period ended June 30, 1998, with
reclassification of comparative financial statements. SFAS No. 130 defines
comprehensive income and outlines certain reporting and disclosure requirements
related to comprehensive income. The Company has no items of other comprehensive
income for either the three months ended June 30, 1997 or 1998.

9.  Commitments and Contingencies:

         Adelphia earned substantially all of its revenues in the three months
ended June 30, 1997 and 1998 from monthly subscriber fees for basic, satellite,
premium and ancillary services (such as installations and equipment rentals),
local and national advertising sales, pay-per-view programming and CLEC
telecommunications services.

         The changes in Adelphia's operating results for the three months ended
June 30, 1998 compared to the same period of the prior year, were primarily the
result of acquisitions, rate increases and expansion of existing operations.

         The high level of depreciation and amortization associated with the
significant number of acquisitions in recent years, the continued upgrade and
expansion of systems and interest costs associated with financing activities
will continue to have a negative impact on the reported results of operations.
Also, significant charges for depreciation, amortization and interest are
expected to be incurred in the future by Olympus, which will adversely impact
Adelphia's future results of operations. Adelphia expects to report net losses
for the next several years.

         The following tables set forth certain cable television system data at
the dates indicated for Company Owned, Olympus and Managed Systems. The "Olympus
Systems" are systems currently owned by Olympus. The "Managed Systems" are
affiliated systems managed by Adelphia.

                                              Three Months Ended
                                                   June 30,
                                             --------------------
                                                1997      1998
                                              --------  --------
Regulated service and equipment fees             75%       73%
Premium programming fees                         12%        9%
Advertising sales and other services             13%       18%



         Revenues increased approximately 18.0% for the quarter ended June 30,
1998 compared with the quarter ended June 30, 1997. The increase was
attributable to the following:


Acquisitions                                          55%
Basic subscriber growth                                5%
Rate increases                                        32%
Premium programming fees                             (10%)
Advertising sales and other services                  18%



         Effective August 1, 1997, certain rate increases related to regulated
cable services were implemented in substantially all of the Company's Systems.
Advertising revenues and revenues derived from other strategic service offerings
such as paging, high-speed data services, long distance and CLEC services also
had a positive impact on revenues for the quarter ended June 30, 1998. The
Company expects to implement rate increases related to certain regulated cable
services in substantially all of the Company's systems during the quarter ending
September 30, 1998.



         Direct Operating and Programming Expenses. Direct operating and
programming expenses, which are mainly basic and premium programming costs and
technical expenses, increased 22.8% for the quarter ended June 30, 1998 compared
with the same quarter of the prior year. Such increase was primarily due to
increased operating expenses from acquired systems, increased programming costs
and incremental costs associated with increased subscribers. Additionally,
Hyperion expenses increased due to expansion of operations at its network
control center, as well as an increase in the number and size of its networks,
which resulted in increased employee related costs and equipment maintenance.

         Selling, General and Administrative Expenses. These expenses, which are
mainly comprised of costs related to system offices, customer service
representatives and sales and administrative employees, increased 30.8% for the
quarter ended June 30, 1998 compared with the same quarter of the prior year.
The increase was primarily due to incremental costs associated with
acquisitions, subscriber growth and Hyperion overhead and network operating and
control center cost increases to accommodate the growth in the number of
networks managed and monitored.

         Depreciation and Amortization. Depreciation and amortization was higher
for the quarter ended June 30, 1998 compared with the same quarter of the prior
year primarily due to increased depreciation and amortization related to
acquisitions consummated during the years ended March 31, 1997 and 1998, as well
as increased capital expenditures made during the past several years.

         Priority Investment Income. Priority investment income is comprised of
payments received from Olympus of accrued priority return on the Company's
investment in 16.5% preferred limited partner ("PLP") interests in Olympus.
Priority investment income increased during the quarter ended June 30, 1998 due
to increased payments by Olympus.

         Interest Expense - Net. Interest expense - net, excluding Hyperion,
increased 1.2% for the quarter ended June 30, 1998 compared with the same
quarter of the prior year. Interest expense - net, including Hyperion, for the
quarter ended June 30, 1998, increased 1.6% as compared with the same quarter of
the prior year. Interest expense increased primarily due to incremental debt 
related to acquisitions and the issuance of the Hyperion 12 1/4% Senior Secured 
Notes. These increases were offset by Hyperion's interest income on cash 
balances.  Interest expense includes noncash accretion of original issue 
discount on the Hyperion 13% Senior Discount Notes and noncash interest expense 
totaling $7,895 for the quarter ended June 30, 1998 compared with $6,858 for the
same quarter of the prior year.

         Equity in Loss of Joint Ventures. The equity in loss of joint ventures
represents primarily (i) the Company's pro rata share of Olympus' losses and the
accretion requirements of Olympus' PLP interests, and (ii) Hyperion's pro-rata
share of its less than majority owned partnerships' operating losses.

         Minority Interest in Losses of Subsidiaries. As a result of Hyperion's
IPO, a portion of Hyperion's net loss applicable to common stockholders is 
attributable to minority interests.

         Hyperion Preferred Stock Dividends. During the quarter ended June 30,
1998, Hyperion incurred $6,946 of expense relating to its 12 7/8% Senior
Exchangeable Redeemable Preferred Stock issued in October 1997.

         Extraordinary Loss on Early Retirement of Debt. During the quarter
ended June 30, 1998, $69,838 of 12 1/2% Senior Notes due 2002 were redeemed at
103% of principal. As a result of this transaction Adelphia recognized an
extraordinary loss on early retirement of debt of $2,604.

         Income Tax Benefit. Income tax benefit for the quarter ended June 30,
1998 is primarily due to the impact of a change in the tax law which extends the
number of years the company can utilize its net operating loss carryforward
generated in the current fiscal year.

Liquidity and Capital Resources

         The cable television and other telecommunication businesses are capital
intensive and typically require continual financing for the construction,
modernization, maintenance, expansion and acquisition of cable and other
telecommunication systems. The Company historically has committed significant
capital resources for these purposes and for investments in Olympus and other
affiliates and entities. These expenditures were funded through long-term
borrowings and, to a lesser extent, internally generated funds. The Company's
ability to generate cash to meet its future needs will depend generally on its
results of operations and the continued availability of external financing.

         The Company has made a substantial commitment to the technological
development of the Systems and is aggressively investing in the upgrade of the
technical capabilities of its cable plant in a cost efficient manner. Over 50%
of Adelphia's networks have bandwidth capacity of 550 Mhz or greater. The
Company continues to deploy fiber optic cable and to upgrade the technical
capabilities of its broadband networks in order to increase network capacity,
digital capability, two-way communication and network reliability.

         The design of the current System upgrade, when completed, will deploy
on average one fiber optic node for every two system plant miles or
approximately one fiber node for every 180 homes passed compared to the industry
norm of 500 to 1000 homes passed per fiber optic node. Approximately 75% of the
System will be upgraded to 750 Mhz. Approximately 25% of the plant will remain
at 550 Mhz. The upgraded system will be completely addressable and provide
two-way communication capability. The additional bandwidth will enable the
Company to offer additional video programming services. A portion of the
bandwidth will be allocated to new service offerings such as two-way data,
telephony and video-on-demand. By the end of fiscal 1999, approximately 50% of
customers will be served by two way cable plant.

         Capital expenditures for Adelphia excluding Hyperion for the quarters
ended June 30, 1997 and 1998 were $24,768 and $30,791, respectively. Capital
expenditures, including Hyperion, for the quarters ended June 30, 1997 and 1998
were $43,534 and $74,255, respectively. Capital expenditures for Hyperion for
the quarter ended June 30, 1998 compared with the quarter ended June 30, 1997,
increased primarily due to the upgrade of plant in markets in which Hyperion
purchased its local partners' interests and the commencement of switching
services. The Company expects that capital expenditures excluding Hyperion for
fiscal 1999 will be in the range of approximately $150,000 to $170,000. Hyperion
estimates that it will require approximately $215,000 to fund anticipated 
capital expenditures, working capital requirements, operating losses and 
investments in its existing and its planned new networks through the end of
fiscal 1999.

         The Company generally has funded its working capital requirements,
capital expenditures and investments in Olympus and other affiliates and
entities through long-term borrowings, primarily from banks and insurance
companies, short-term borrowings, internally generated funds and the issuance of
parent company public debt and equity and Hyperion public debt and equity. The
Company generally has funded the principal and interest obligations on its
long-term borrowings from banks and insurance companies by refinancing the
principal with new loans or through the issuance of parent company debt or
equity securities, and by paying the interest out of internally generated funds.
Adelphia has funded the interest obligations on its public borrowings from
internally generated funds.

         The Company's financing strategy has generally been to maintain its
public long-term debt at the parent holding company level while the Company's
consolidated subsidiaries have their own senior and subordinated credit
arrangements with banks and insurance companies or, for Hyperion, its own public
debt and equity. The Company's public indentures and subsidiary credit
agreements contain covenants that, among other things, require the maintenance
of certain financial ratios (including compliance with certain debt to cash flow
ratios in order to incur additional indebtedness); place limitations on
borrowings, investments, affiliate transactions, dividends and distributions;
and contain certain cross default provisions relating to Adelphia or its
subsidiaries.

         At June 30, 1998, the Company's total outstanding debt aggregated
$2,996,821, which included $1,510,596 of parent debt, $500,177 of Hyperion debt
and $986,048 of other subsidiary debt. At June 30, 1998, Adelphia's subsidiaries
had an aggregate of $80,120 in unused credit lines with banks and institutions.
In addition, the Company had an aggregate $454,676 in cash and cash equivalents
at June 30, 1998, which combined with the Company's unused credit lines with
banks, aggregated $534,796.

         At June 30, 1998, the Company's unused credit lines were provided by
reducing revolving credit facilities whose revolver periods expire December 31,
2004. The Company's weighted average interest rate on notes payable to banks and
institutions was approximately 8.39% at June 30, 1997 compared to 7.32% at June
30, 1998. At June 30, 1998, approximately 11% of such debt was subject to fixed
interest rates for at least one year under the terms of such debt or applicable
interest rate swap agreements.

         The following table sets forth the mandatory reductions in principal
under all debt agreements for each of the next four years and nine months based
on amounts outstanding at June 30, 1998:

      Nine months ending March 31, 1999                     $    143,637
      Year ending March 31, 2000                                 117,269
      Year ending March 31, 2001                                 235,588
      Year ending March 31, 2002                                 158,740
      Year ending March 31, 2003                                 503,253

         Reference is made to Note 1 of the condensed consolidated financial
statements for discussion of significant events and financings subsequent to
March 31, 1998, which is incorporated by reference herein.

         The Company plans to continue to explore and consider new commitments,
arrangements or transactions to refinance existing debt, increase the Company's
liquidity or decrease the Company's leverage. These could include, among other
things, the future issuance by Adelphia, or its subsidiaries, of public or
private equity or debt and the negotiation of new or amended credit facilities.
These could also include entering into acquisitions, joint ventures or other
investment or financing activities, although no assurance can be given that any
such transactions will be consummated. The Company's ability to borrow under
current credit facilities and to enter into refinancings and new financings is
limited by covenants contained in Adelphia's indentures and its subsidiaries'
credit agreements, including covenants under which the ability to incur
indebtedness is, in part, a function of applicable ratios of total debt to cash
flow.

         The Company believes that cash and cash equivalents, internally
generated funds, borrowings under the existing credit facilities, and future
financing sources will be sufficient to meet its short-term and long-term
liquidity and capital requirements. Although in the past the Company has been
able to refinance its indebtedness or obtain new financing, there can be no
assurance that the Company will be able to do so in the future or that the terms
of such financings would be favorable.

         Management believes that the telecommunications industry, including the
cable television and telephone industries, continues to be in a period of
consolidation characterized by mergers, joint ventures, acquisitions, sales of
all or part of cable or telephone companies or their assets, and other
partnering and investment transactions of various structures and sizes involving
cable or other telecommunications companies. The Company continues to evaluate
new opportunities that allow for the expansion of its business through the
acquisition of additional cable television systems in geographic proximity to
its existing regional markets or in locations that can serve as a basis for new
market areas. The Company, like other cable television companies, has
participated from time to time and is participating in preliminary discussions
with third parties regarding a variety of potential transactions, and the
Company has considered and expects to continue to consider and explore potential
transactions of various types with other cable and telecommunications companies.
However, no assurances can be given as to whether any such transaction may be
consummated or, if so, when, or that additional competition from this industry
consolidation will not have an adverse effect on the Company..

Regulatory and Competitive Matters

         The cable television operations of the Company may be adversely
affected by changes and developments in governmental regulation, competitive
forces and technology. The cable television industry and the Company are subject
to extensive regulation at the federal, state and local levels. The 1992 Cable
Act significantly expanded the scope of regulation of certain subscriber rates
and a number of other matters in the cable industry, such as mandatory carriage
of local broadcast stations and retransmission consent, and increased the
administrative costs of complying with such regulations. The FCC has adopted
rate regulations that establish, on a system-by-system basis, maximum allowable
rates for (i) basic and cable programming services (other than programming
offered on a per-channel or per-program basis), based upon a benchmark
methodology, and (ii) associated equipment and installation services based upon
cost plus a reasonable profit. Under the FCC rules, franchising authorities are
authorized to regulate rates for basic services and associated equipment and
installation services, and the FCC will regulate rates for regulated cable
programming services in response to complaints filed with the agency. The
Telecommunications Act of 1996 (the "1996 Act") ends FCC regulation of cable
programming service tier rates on March 31, 1999.

         Rates for basic and cable programming services are set pursuant to a
benchmark formula. Alternatively, a cable operator may elect to use a
cost-of-service methodology to show that rates for basic and cable programming
services are reasonable. Refunds with interest will be required to be paid by
cable operators who are required to reduce regulated rates. The FCC has reserved
the right to reduce or increase the benchmarks it has established. The rate
regulations also limit increases in regulated rates to an inflation indexed
amount plus increases in certain costs such as taxes, franchise fees, costs
associated with specific franchise requirements and increased programming costs.
Cost-based adjustments to these capped rates can also be made in the event a
cable operator adds or deletes channels or completes a significant system
rebuild or upgrade. Because of the limitation on rate increases for regulated
services, future revenue growth from cable services will rely to a much greater
extent than has been true in the past on increased revenues from unregulated
services and new subscribers than from increases in previously unregulated
rates.

         The FCC has adopted regulations implementing all of the requirements of
the 1992 Cable Act. The FCC is also likely to continue to modify, clarify or
refine the rate regulations. Adelphia cannot predict the effect of the 1996 Act
or future legislative or rulemaking proceedings or changes to the rate
regulations. No assurance can be given as to what other future actions Congress,
the FCC or other regulatory authorities may take or the effects thereof on
Adelphia.

         Cable television companies operate under franchises granted by local
authorities which are subject to renewal and renegotiation from time to time.
Because such franchises are generally non-exclusive, there is a potential for
competition with the systems from other operators of cable television systems,
including public systems operated by municipal franchising authorities
themselves, and from other distribution systems capable of delivering television
programming to homes. The 1992 Cable Act and the 1996 Act contain provisions
which encourage competition from such other sources. The Company cannot predict
the extent to which competition will materialize from other cable television
operators, local telephone companies, other distribution systems for delivering
television programming to the home, or other potential competitors, or, if such
competition materializes, the extent of its effect on the Company.

         The 1996 Act repealed the prohibition on CLECs from providing video
programming directly to customers within their local exchange areas other than
in rural areas or by specific waiver of FCC rules. The 1996 Act also authorized
CLECs to operate "open video systems" ("OVS") without obtaining a local cable
franchise, although CLECs operating such a system can be required to make
payments to local governmental bodies in lieu of cable franchise fees. Where
demand exceeds capacity, up to two-thirds of the channels on an OVS must be
available to programmers unaffiliated with the CLEC. The statute states that the
OVS scheme supplants the FCC's "video dialtone" rules. The FCC has promulgated
rules to implement the OVS concept, and New Jersey Bell Telephone Company has
been granted permission to convert its video dialtone authorization in Dover
Township, New Jersey to an OVS authorization.

         The Company believes that the provision of video programming or other
services by telephone companies in competition with the Company's existing
operations could have an adverse effect on the Company's financial condition and
results of operations. At this time, the impact of any such effect is not known
or estimable.

         The Company also competes with DBS service providers. DBS has been
available to consumers since 1994. A single DBS satellite can provide more than
100 channels of programming. DBS service can be received virtually anywhere in
the United States through the installation of a small outdoor antenna. DBS
service is being heavily marketed on a nationwide basis by several service
providers. Although the impact to date has not been material, any future impact
of DBS competition on the Company's future results is not known or estimable.

Year 2000 Issues

         The year 2000 issue is the result of computer programs being written
using two digits rather than four to define the applicable year. Any of the
Company's 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 disruptions of operations,
including, among other things, a temporary inability to process transactions,
send invoices, or engage in similar normal business activities.

         The Company has recently completed the planning stage of a project that
addresses the year 2000 data processing issues relating to modifications of its
mainframe computer applications. Internal and external resources are being used
to make the required modifications and perform the necessary tests, all of which
is expected to be completed by June 1999. The financial impact of these
modifications is not expected to be significant to the Company's financial
statements.

         In addition, the Company has begun communicating with others with whom
it does significant business to determine their year 2000 compliance readiness
and the extent to which the Company is vulnerable to any third party year 2000
issues. However, there can be no guarantee that the systems of other companies
on which the Company's systems rely will be timely converted, or that a failure
to convert by another company, or a conversion that is incompatible with the
Company's systems, would not have a material adverse effect on the Company.
