placement of 5,901,522 shares of Adelphia Class B common stock with Highland
2000, L.P., a limited partnership owned by the Rigas family. Adelphia used a
portion of the proceeds of approximately $375,000 from this direct placement to
repay borrowings under revolving credit facilities of its subsidiaries, which
may be reborrowed and used for general corporate purposes.

         During January 2000, Adelphia Business Solutions entered into an IRU
agreement with Level 3 Communications ("Level 3") for approximately 3,100
long-haul route miles throughout much of the western United States. In addition,
Adelphia Business Solutions entered into an agreement with Level 3 to acquire
access to approximately 750 miles of metro duct in the following central
business districts: Chicago, Cincinnati, Dallas, Denver, Detroit, Los Angeles,
Orlando, Phoenix, San Diego, San Francisco, San Jose and Seattle. The total cost
of the agreement is approximately $54,600.

         During April 2000, Adelphia Business Solutions was the successful
bidder, in the Federal Communications Commission ("FCC") auction, for 177
licenses in the 39 Ghz spectrum covering approximately 164,000,000 Points of
Presence ("POPS"). Adelphia Business Solutions has deposited $15,000 of the
total $77,605 purchase price with the remaining balance due at the time the
licenses are granted. On July 31, 2000, a petition to deny was filed against
Adelphia Business Solutions. This petition does not seek to deny the grant of
the licenses to Adelphia Business Solutions, but instead, seeks only to make
such grant subject to petitioners' previously dismissed applications seeking
spectrum covered by Adelphia Business Solutions licenses. Adelphia Business
Solutions believes the petition is without merit and intends to vigorously
oppose it and Adelphia Business Solutions currently believes its licenses will
be granted during the third or fourth quarter of 2000.

         On April 14, 2000, Adelphia closed on a $2,250,000 bank credit
facility on behalf of certain subsidiaries and affiliates. The credit facility
consists of a $1,500,000 8 3/4 year reducing revolving credit loan and
a $750,000 9 year term loan.

         On May 1, 2000, Adelphia and AT&T completed a swap of cable systems
serving approximately 13,000 basic subscribers. As a result of this transaction,
the Company recorded a gain of approximately $37,600.

         On May 3, 2000, Adelphia Business Solutions entered into a contract to
build an advanced technology infrastructure and to provide communication
services to the Commonwealth of Pennsylvania state government.  As part of the
contract Adelphia Business Solutions was required to place $75,785 into a
restricted account to be used for completion of the technology infrastructure.

         On June 13, 2000, Adelphia announced that it had entered into
agreements regarding the acquisition of cable systems, including GS
Communications, Inc., which will add approximately 155,000 basic subscribers to
its Virginia cluster for an aggregate purchase price of $836,000. It is
currently anticipated that these transactions, which are subject to customary
closing conditions and the receipt of regulatory approvals, will close in the
first quarter of 2001.

         On July 3, 2000, Adelphia closed the previously announced direct
placement of 2,500,000 shares of Adelphia Class B common stock with Highland
2000, L.P., a limited partnership owned by the Rigas family. Adelphia used a
portion of the proceeds of approximately $145,000 from this direct placement to
repay borrowings under revolving credit facilities of its subsidiaries, which
may be reborrowed and used for general corporate purposes.

         On July 5, 2000, Adelphia acquired Prestige Communications of NC, Inc.
These systems served approximately 118,250 subscribers in North Carolina,
Virginia and Maryland at the date of acquisition and were purchased for an
aggregate price of approximately $700,000. The acquisition was accounted for
under the purchase method of accounting. Accordingly, the financial results of
the acquired systems will be included in the consolidated results of Adelphia
effective from the date acquired.

         During July 2000, Adelphia Business Solutions consummated a purchase
agreement with a subsidiary of Allegheny Energy, Inc. ("Allegheny") to acquire
interests in a jointly owned network located in State College, Pennsylvania.
Consideration paid to Allegheny was 330,000 shares of Adelphia Business
Solutions' Class A common stock. The purchase increased Adelphia Business
Solutions' ownership in this network to 100%. The acquisition will be accounted
for under the purchase method of accounting. Accordingly, the financial results
of the acquired network will be included in the consolidated results of Adelphia
Business Solutions effective from the date acquired.

         On August 2, 2000, 80,000 shares of Series C convertible preferred
stock held by Highland Holdings, a general partnership owned by the Rigas
family, were converted into 9,433,962 shares of Adelphia Class A common stock.

         In addition to the acquisitions mentioned above, prior to
August 14, 2000, Adelphia completed certain other cable system acquisitions.
These acquisitions served approximately 16,000 basic subscribers at the date of
acquisitions primarily in Colorado, New York and Maine and were purchased for an
aggregate price of approximately $70,000, comprised of Adelphia Class A common
stock and cash. These acquisitions will be accounted for under the purchase
method of accounting. Accordingly, the financial results of the acquired systems
will be included in the consolidated results of Adelphia effective from the date
acquired.

         Adelphia completed several significant acquisitions during the quarter
ended December 31, 1999. Reference is made to Note 1 to the consolidated
financial statements contained in the Annual Report on Form 10-K for the year
ended December 31, 1999 for additional information regarding these acquisitions.

         In July 2000, certain members of the Rigas family closed on their
agreement to acquire all the voting interests of Niagara Frontier Hockey, L.P.
("NFHLP"). All necessary third party approvals of the agreement have been
received.

4.  Related Party Receivables - Net:

         Related party receivables - net represent advances to and management
fees and other fees from managed partnerships, the Rigas family and Rigas family
controlled entities. No related party advances are collateralized.

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 and outstanding stock options had an
antidilutive effect for the periods presented; however, the convertible
preferred stock and outstanding stock options could have a dilutive effect on
earnings per share in future periods.

10. Recent Accounting Pronouncements:

         Statement of Financial Accounting Standards ("SFAS") No. 133,
"Accounting for Derivative Instruments and Hedging Activities," establishes
accounting and reporting standards for derivative instruments and for hedging

assets or liabilities in the statement of financial position and measure those
instruments at fair value. In June 2000, SFAS No. 138 was issued which amends
the accounting and reporting standards of SFAS No. 133 for certain derivative
instruments and certain hedging activities. Management of the Company has not
completed its evaluation of the impact of SFAS No. 133 on the Company's
consolidated financial statements. The Company will be required to adopt such
standards effective January 1, 2001.

         Adelphia earned substantially all of its revenues in the three and six
months ended June 30, 1999 and 2000 from monthly subscriber fees for basic,
satellite, premium and ancillary services (such as installations and equipment
rentals), CLEC telecommunications services, local and national advertising
sales, high speed data services and pay-per-view programming.

         The changes in Adelphia's operating results for the three and six
months ended June 30, 2000 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.
Adelphia expects to report net losses for the next several years.

         Adelphia completed numerous acquisitions during the year ended December
31, 1999. The Company completed the acquisition of Olympus Communications, L.P.
("Olympus") partnerships interests held by FPL Group, Inc. and the acquisitions
of FrontierVision Partners, L.P. ("FrontierVision"), Harron Communication Corp.,
and Arahova Communications, Inc. ("Arahova") (formerly Century Communications
Corp.). These acquisitions occurred on October 1, 1999 and are collectively
referred to as the Acquisitions. Reference is made to Note 1 of the consolidated
financial statements contained in Adelphia's Annual Report on Form 10-K for the
year ended December 31, 1999 for additional information regarding these
acquisitions.

         The following tables set forth certain cable television system data at

         During the previous twelve months, certain rate increases related to
cable services were implemented in the majority of the Company's systems.
Advertising revenues and revenues derived from other strategic service offerings
such as high-speed data services, long distance services and paging also had a
positive impact on revenues for the three and six months ended June 30, 2000.


         Direct Operating and Programming Expenses. Direct operating and
programming expenses, which are mainly basic and premium programming costs and
technical expenses, increased 258.8% and 255.7% to $218,710 and $425,974 for the

<PAGE>

three and six months ended June 30, 2000, respectively, from $60,964 and
$119,755 for the same periods of 1999. Acquisitions accounted for substantially
all of the increase for the quarter ended June 30, 2000, while being partially
offset by operational efficiencies recognized in connection with the
acquisitions.

         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 271.5% and
282.3% to $107,655 and $218,197 for the three and six months ended June 30,
2000, respectively, from $28,979 and $57,081 for the same periods of 1999.
Acquisitions accounted for 95.4% and 92.6% of the increase for the three and six
months ended June 30, 2000, respectively. The remaining increase was due
primarily to subscriber growth, new services, and an increase in administrative
employees due to the recently completed acquisitions.

         Depreciation and Amortization. Depreciation and amortization increased
266.2% and 290.3% to $183,638 and $364,679 for the three and six months ended
June 30, 2000, respectively, from $50,150 and $93,430 for the same periods of
1999. Acquisitions accounted for substantially all of the increase for the
quarter ended June 30, 2000.

         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 prior
to the consolidation of Olympus effective October 1, 1999.

         Interest Expense - Net. Interest expense - net increased 304.4% and
267.5% to $193,993 and $384,882 for the three and six months ended June 30,
2000, respectively, from $47,969 and $104,726 for the same periods of 1999.
Acquisitions accounted for 99.7% and 92.0% of the increase for the three and six
months ended June 30, 2000, respectively. The remaining increase was primarily
due to an increase in average debt outstanding and higher interest rates.

         Equity in Loss of Olympus and Other Joint Ventures. The equity in loss
of Olympus and other joint ventures represents primarily (i) the Company's
pro-rata share of Olympus' losses and the accretion requirements of Olympus' PLP
interests, and (ii) Adelphia's pro-rata share of its less than majority owned
partnerships' operating losses. Equity in loss of joint ventures decreased in
the three months ended June 30, 2000, compared to the same period in 1999,
primarily due to the consolidation of Olympus effective October 1, 1999.

         Preferred Stock Dividends. Preferred stock dividends increased 121.6%
to $14,406 and $28,812 for the three and six months ended June 30, 2000,
respectively, from $6,500 and $13,000 for the same periods of 1999. The increase
is due to the dividends on the Series D convertible preferred stock issued in
April 1999.

         Minority Interest in Net Losses of Subsidiaries. Minority interest in
net losses of subsidiaries increased 159.0% and 103.2% to $34,045 and $52,956
for the three and six months ended June 30, 2000, respectively, from $13,146 and
$26,060 for the same periods for 1999. The increase was primarily due to
increased net losses of less than wholly-owned subsidiaries attributable to
minority interests, offset partially by net income of certain less than
wholly-owned subsidiaries of the Acquisitions.

         Gain on Asset Swap. On May 1, 2000, Adelphia swapped certain cable
systems for certain cable systems owned by AT&T. The result of this transaction
was a gain of $37,552 for the three and six months ended June 30, 2000.

</TABLE>

         The increase in direct operating and programming expense was due to
start up costs in Adelphia Business Solutions' new markets as regional switches
and network rings were activated, combined with start up costs in Adelphia
Business Solutions' original markets associated with Adelphia Business

         Depreciation and Amortization. Depreciation and amortization expense
increased 96% and 70% to $26,689 and $46,127 during the three and six months
ended June 30, 2000, respectively, from $13,586 and $27,121 for the same periods
in the prior year primarily as a result of increased depreciation resulting from
the higher depreciable asset base at the NOCC and the networks, amortization of
deferred financing costs and the acquisition of local partner interests.

         Interest Expense - Net. Interest expense - net increased 206% and 37%
to $12,985 and $20,488 during the three and six months ended June 30, 2000,
respectively, from $4,246 and $14,953 for the same period in the prior year. The
increase was primarily attributable to a decrease in interest income.

         Equity in Net Loss of Joint Ventures. Equity in net loss of joint
ventures decreased 90% and 94% to $346 and $451 during the three and six months
ended June 30, 2000, respectively, from $3,291 and $7,094 for the same periods
in the prior year as a result of the consolidation of several joint ventures
resulting from the purchase of the local partners' interests, and the maturing
of the remaining joint venture networks.

         The number of joint ventures paying management fees to Adelphia
Business Solutions decreased from seven at June 30, 1999 to four at June 30,
2000 due to Adelphia Business Solutions' increased ownership in several joint
ventures. These non-consolidated joint ventures and networks under construction
paid management and monitoring fees to Adelphia Business Solutions, which are
included in revenues, aggregating approximately $1,136 and $2,236 for the three
and six months ended June 30, 2000, as compared with $1,032 and $2,609 for the
same periods in the prior fiscal year. The nonconsolidated joint ventures' net
losses, including networks under construction, for the three months ended June
30, 1999 and 2000, aggregated approximately $2,491 and $564, respectively and
for the six months ended June 30, 1999 and 2000 aggregated approximately $4,712
and $1,200, respectively.

         Adelphia Business Solutions' Preferred Stock Dividends. Preferred stock
dividends increased by 13% to $8,909 and $17,545 for the three and six months
ended June 30, 2000 from $7,860 and $15,479 for the same periods in the prior
year. The increase was due to a higher outstanding preferred stock base
resulting from the payments of dividends in additional shares of preferred
stock.

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 affiliates and other
entities. These expenditures were funded through long-term borrowings, the sale
of common and preferred stock 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.

         For the six months ended June 30, 1999, cash provided by operating
activities totaled $28,421 and for the six months ended June 30, 2000, cash used
for operating activities totaled $38,843; for the six months ended June 30, 1999
and 2000, cash used for investing activities totaled $1,038,390 and $940,634,
respectively and cash provided by financing activities totaled $1,414,026 and
$931,842, respectively. See Note 1 to the condensed consolidated financial
statements, in Part I, Item 1 for a summary of significant transactions
affecting liquidity and capital resources subsequent to December 31, 1999, which
is incorporated by reference herein.

Capital Expenditures

       Cable and Other Segment

         Capital expenditures for the six months ended June 30, 1999 and 2000
were $94,955 and $454,568, respectively. This increase was primarily due to
acquisitions and cable plant rebuilds and upgrades to expand services. The
Company expects that capital expenditures for the Cable and Other Segment for
the year ending December 31, 2000 will be in a range of approximately $700,000
to $900,000.

       CLEC Segment

         Capital expenditures for the six months ended June 30, 1999 and 2000
were $131,831 and $290,900, respectively. This increase was primarily due to
expenditures necessary to develop its markets, as well as the fiber purchases to
interconnect the networks. Adelphia Business Solutions estimates that a total of
approximately $350,000 will be required to fund Adelphia Business Solutions
capital expenditures, working capital requirements, operating losses and pro
rata investments in the joint ventures through the year ending December 31,
2000.

Financing Activities

         The Company's financing strategy has 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 Adelphia Business
Solutions, Olympus, FrontierVision and Arahova, their own public debt and/or
equity. The Company generally has funded its acquisitions, working capital
requirements, capital expenditures and investments in affiliates and other
entities through long-term borrowings, primarily from banks and insurance
companies, short-term borrowings, internally generated funds and the issuance of
public debt or equity. The Company generally has funded the principal and
interest obligations on its long-term borrowings from banks and insurance

<PAGE>

companies by refinancing the principal with new loans or through the issuance of
parent and subsidiary 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 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, 2000, the Company's total outstanding debt aggregated
$9,978,775, which included $2,778,572 of parent debt, $967,100 of Adelphia
Business Solutions debt, $203,278 of Olympus public debt, $509,985 of
FrontierVision public debt, $1,869,970 of Arahova public debt and $3,649,870 of
other subsidiary debt. The Company also had total redeemable preferred stock of
$426,842 outstanding as of June 30, 2000. As of June 30, 2000, Adelphia's
subsidiaries had an aggregate of $2,396,752 in unused credit lines and cash and
cash equivalents, which includes $547,363 also available to affiliates, part of
which is subject to achieving certain levels of operating performance.

         On April 14, 2000, Adelphia closed on a $2,250,000 bank credit facility
on behalf of certain subsidiaries and affiliates.. The credit facility consists
of a $1,500,000 8 3/4 year reducing revolving credit loan and a $750,000 9 year
term loan. Proceeds from this credit facility were used to complete the
July 5, 2000 acquisition of Prestige Communications of NC, Inc.

         The Company's weighted average interest rate on notes payable to banks
and institutions was approximately 8.78% at June 30, 1999 compared to 8.37% at
June 30, 2000. Approximately 71% of the Company's total indebtedness was at
fixed interest rates as of June 30, 2000, after giving effect to certain
interest rate swaps, caps and collars.

         The following table sets forth the mandatory reductions in principal
under all debt agreements for each of the next four years and six months based
on amounts outstanding at June 30, 2000:

                      Year ending December 31, 2004                              853,268

Resources

         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.
<PAGE>

         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 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") ended FCC regulation of cable programming service
tier rates on March 31, 1999.

         Rates for basic and certain 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.
<PAGE>

         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.

         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. New Jersey Bell Telephone Company
terminated its OVS operation in Dover Township, New Jersey at the end of 1998.
Recently, RCN Telecom Services, Inc. has been granted permission to convert its
video dialtone authorization in the Philadelphia Region 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 direct broadcast satellite ("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. Congress passed the Satellite Home Viewer
Act in 1999 which allows DBS providers to begin offering local broadcast
channels. DBS companies have since added a limited number of local channels in
some regions, a trend that will continue, thus lessening the distinction between
cable television and DBS service. 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.

Item 3.  Quantitative and Qualitative Disclosures about Market Risk

         The Company uses fixed and variable rate debt to fund its working
capital requirements, capital expenditures and acquisitions. These debt
arrangements expose the Company to market risk related to changes in interest
rates. The Company enters into pay-fixed agreements to effectively convert a
portion of its variable-rate debt to fixed-rate debt to reduce the risk of
incurring higher interest costs due to rising interest rates. As of June 30,
2000, the Company had interest rate swap agreements covering notional principal
of $90,000 that expire through 2008 and that fix the interest rate at an average
of 6.12%. The Company also enters into receive-fixed agreements to effectively
convert a portion of its fixed-rate debt to a variable-rate debt which is
indexed to LIBOR to reduce the risk of incurring higher interest costs in
periods of falling interest rates. As of June 30, 2000, the Company had interest
rate swap agreements covering notional principal of $80,000 that expire through
2003 and that have a variable rate at an average of 6.74%. The Company enters
into interest rate cap agreements to reduce the risk of incurring higher
interest costs due to rising interest rates. As of June 30, 2000, the Company
had interest rate cap agreements covering a notional amount of $400,000, which
expire in 2002 and cap rates at an average rate of 7.25%. As of June 30, 2000,
the Company had interest rate collar agreements covering a notional amount of
$200,000, with $100,000 expiring in each of 2001 and 2002. The interest rate
collar agreements have average floor rates of 5.95% and 6.30% and average cap
rates of 5.95% and 6.30%, respectively. These agreements also have maximum cap
rates of 6.64% and minimum floor rates of 4.65% and 4.95%, respectively. The
Company does not enter into any interest rate swap, cap or collar agreements for
trading purposes. The Company is exposed to market risk in the event of
non-performance by the banks. No such non-performance is expected. The table
below summarizes the fair values and contract terms of the Company's financial
instruments subject to interest rate risk as of June 30, 2000.

                           PART II - OTHER INFORMATION

Item 1.  Legal Proceedings

         On or about March 24, 2000, ML Media Partners, L.P. ("ML Media")
commenced an action by filing a Verified Complaint (the "Complaint") in the
Supreme Court of the State of New York, New York County, against Arahova
Communications, Inc. ("Arohova"), Century Communications Corp., a Texas
subsidiary of Arahova ("Century"), and Adelphia. In the nine count Complaint, ML
Media alleges that it entered into a joint venture agreement (the "Agreement")
with Century which, as subsequently modified, governed the ownership, operation
and disposition of cable television systems in Puerto Rico (the "Joint
Venture"). The Complaint alleges that Adelphia and its affiliates took over
Century's interest in the Joint Venture on or around October 1, 1999, and have,
according to the Complaint, breached their fiduciary obligations to the Joint
Venture and violated certain provisions of the Agreement. The Complaint further
alleges that ML Media gave Century notice that ML Media was exercising its
rights under the Agreement to require that Century elect to (A) purchase ML
Media's interest in the Joint Venture at an appraised fair value, or (B) seek to
sell the cable systems to one or more third parties. Century, according to the
Complaint, elected to pursue the sale of the cable systems and indicated that it
was evaluating whether it or an affiliate thereof would make an offer for the
cable systems. The Complaint alleges that Century or its affiliates' potential
participation in the sale process is improper. The Complaint asks for, among
other things, the dissolution of the Joint Venture and the appointment of a
receiver to effect a prompt sale of the Joint Venture. The parties completed
discovery in the action and each filed motions for partial summary judgment. On
July 10, 2000, Justice Gammerman granted ML Media's motion for partial summary
judgment on the fourth cause of action and declared that neither Century nor any
of its affiliates may bid on or attempt to purchase the assets and business of
the Joint Venture. Justice Gammerman also dismissed the fourth count of the
counterclaim and required Century to proceed diligently with ML Media in
locating one or more third parties to complete the sale and prohibited any
defendant from interfering with the sale. On July 26, 2000, the Justice also
ordered that the sale may be a sale of either the assets of the Joint Venture or
the partnership interests in the Joint Venture. The Justice did not address
other issues concerning the motion for summary judgment and did not schedule a
full hearing on the merits. On August 7, 2000, Arahova and the other defendants
filed a notice of appeal with respect to the above described orders and judgment
of the Court. The management of Adelphia and Arahova intend to vigorously defend
this action. Management believes that this matter will not have a material
adverse effect on the Company.

         In November, 1999, Arahova, a subsidiary of Adelphia, has been sued in
a class-action case, Galley vs. American Telephone & Telegraph Corp. et al.,
where the plaintiffs allege, that by requiring customers to purchase the @Home
service, rather than offering the option of access alone, Arahova and the other
defendant MSO's are illegally "tying" internet content to internet access,
thereby violating both the federal antitrust laws and California unfair trade
practice statutes. The plaintiffs also allege that the defendants have entered
into an illegal conspiracy to require all MSO's providing, or desiring to
provide, the @Home service to enter into contracts precluding them from offering
any competing internet service. The plaintiffs have recently filed an amended
complaint alleging that the violations are national in scope (rather than merely
local). Arahova is vigorously defending this case. Due to the preliminary nature
of the litigation, the outcome cannot be predicted.

         Adelphia and certain subsidiaries are defendants in several putative
subscriber class action suits in state courts in Pennsylvania and Mississippi
initiated during 1999. The suits all challenge the propriety of late fees
charged by the subsidiaries to customers who fail to pay for services in a
timely manner. The suits seek injunctive relief and various formulations of
damages under various claimed causes of action under various bodies of state
law. These actions are in various stages of defense and are being defended
vigorously. The outcome of these matters cannot be predicted at this time. In

<PAGE>

May 2000, Adelphia settled similar litigation in the state courts of Vermont.
The settlement of this matter did not have a material adverse effect.

         There are no other material pending legal proceedings, other than
routine litigation incidental to the business, to which the Company is a part of
or which any of its property is subject.
