          ADELPHIA BUSINESS SOLUTIONS, INC ANNOUNCES SECOND QUARTER
                              RESULTS OF OPERATIONS


                        Coudersport, PA - August 10, 2001




John J. Rigas, Chairman of Adelphia Communications Corporation ("Adelphia")
(NASDAQ: ADLAC) and Adelphia Business Solutions, Inc. ("the Company") (NASDAQ:
ABIZ) reported results of operations for the Company for the second quarter
which ended on June 30, 2001. Second quarter results saw record levels of
consolidated operating revenues of $116.9 million. Net loss applicable to common
stockholders for the second quarter totaled $82.2 million, or $0.61 per share,
compared with $73.6 million, or $1.06 per share, for the same period in the
prior year. Summarized financial results are included in Tables 1, 2, and 3
below.

As presented in Table 1, consolidated revenues increased by 46% to $116.9
million in the June 2001 quarter, from $80.2 million in the June 2000 quarter
and were approximately 6% higher than the March 2001 quarter, from $110.3
million. Consolidated revenues were comprised of voice revenue (includes local,
long-distance and other revenues) of $90.5 million in the June 2001 quarter as
compared with $64.5 million in the June 2000 quarter and data revenue (includes
internet, dedicated access and data services) of $26.4 million in the June 2001
quarter as compared with $15.7 million in the June 2000 quarter. Average revenue
per installed access line in the June 2001 quarter was approximately $49 per
month, or the same as the prior quarter. Consolidated revenues in the June 2001
quarter included $10.7 million of reciprocal compensation revenue, or 9.2% of
revenues. The Company continues to expect calendar 2001 revenues to be
approximately $475 million to $500 million. As a result of continued execution
of its revised business plan, the Company expects EBITDA losses to decrease to
approximately $2 to $5 million for the third quarter of calendar 2001 and to a
total of approximately $20 million for the full year of calendar 2001.




Consolidated gross margin as a percent of sales was 47.0% in the June 2001
quarter as compared with 44.9% of sales in the March 2001 quarter, a 200 basis
point improvement. The Company expects gross margin as a percent of sales will
continue to improve during the third quarter and throughout the remainder of
calendar 2001 as the Class of 1999 and 2000 markets become operational and
customers are moved to our own network. Consolidated EBITDA losses for the June
2001 quarter were in line with Company expectations at $8.7 million versus a
$15.3 million EBITDA loss for the March 2001 quarter. Contribution of higher
gross margin in each of its Class market results, combined with the Company
achieving its goal of reducing selling, general and administrative costs
associated with previous market expansion efforts, contributed to the improved
financial performance. Also, the Company's TSR access line count has been
reduced by over 62,000 lines as a result of the Company's TSR conversion
efforts, further contributing to the positive gross margin contributions during
the June 2001 quarter. The Company expects TSR lines will represent less than
25% of its installed access lines by year end.

As shown in Table 2, the Company's thirteen Class of 1996 markets continue to
demonstrate strong financial results with sequential quarterly revenue growth of
4.8% in the June 2001 quarter and gross margin as a percentage of sales of
70.1%. Revenue for the Class of 1996 markets increased 34.8% as compared with
the June 2000 quarter, with gross margins in excess of 70.0% of revenues for
each of the past seven quarters. As such, EBITDA for these markets before
allocation of corporate overhead increased 108.4% from an annualized $72.1
million for the June 2000 quarter to an annualized $150.3 million for the June
2001 quarter. Furthermore, from the June 2000 quarter to the June 2001 quarter,
the eight Class of 1997/1998 markets' revenues increased 51.7% from $11.9
million to $18.1 million. Gross margins for these markets increased 96.2% from
the June 2000 quarter to the June 2001 quarter and EBITDA before allocation of
corporate overhead increased from $6.4 million to $26.6 million on an annualized
basis and to 36.7% of revenues in the June 2001 quarter.

The Class of 1999 markets also contributed to the Company's improved financial
performance with revenue growth of 58.6% as compared to the June 2000 quarter.
Gross margins in the June 2001 quarter also improved by $3.2 million, a 54.7%
improvement as compared with the March 2001 quarter as a result of a greater
percentage of the Company's customers being served on the newly lit fiber-optic
networks in these markets. EBITDA losses before allocation of corporate overhead
decreased to $21.8 million for the June 2001 quarter compared to $23.8 million
in the March 2001 quarter. The Class of 2000 markets had EBITDA losses before
allocation of corporate overhead which decreased from $4.3 million in the March
2001 quarter to $4.2 million in the June 2001 quarter. As such, in the June 2001
quarter, each of the Company's Class market groupings demonstrated improved
EBITDA performance for the second consecutive quarter, with overall EBITDA
before allocation of corporate overhead of positive $18.2 million, an almost
100% improvement, compared to positive $9.4 million in the March 2001 quarter.
In addition, the June 2001 quarter represented the first quarter in which the
Company's combined financial performance of all of its class markets after
corporate overhead resulted in positive EBITDA of approximately $4 million.

Days sales outstanding in accounts receivable was at about the same level at 84
days as of June 30, 2001 as compared with 83 days at March 31, 2001. The Company
expects days sales outstanding will decrease during the remainder of the year.
As of June 30, 2001, total gross property, plant and equipment of the Company
and its consolidated subsidiaries, was approximately $2.0 billion. The Company's
condensed consolidated balance sheets are attached on Table 3.

During the June 2001 quarter, the Company and its consolidated subsidiaries
invested approximately $120.5 million in capital expenditures related primarily
to local market construction, regional network ring activations, and the central
office build-out for the Class of 1999 and 2000 markets. The Company continues
to expect full-year calendar 2001 capital expenditures to be approximately
$450-$470 million. During the past several months, the Company has evaluated its
capital spending needs to complete its current 75-80 market business plan. As a
result of a combination of factors, including; (i) lower costs of customer
premise and central office electronics, (ii) lower capital costs to activate the
Company's regional long-haul fiber rings, (iii) the ability to purchase
long-haul transport capacity at much lower costs than originally forecasted and
(iv) the successful completion of several metro transport fiber swaps to add
network capacity to new markets at lower than originally forecasted levels, the
Company now believes that the total amount of capital expenditures required to
complete its current business plan over the next 3-4 years will be lower than
originally projected by approximately $350 million, or 20%.


During the June 2001 quarter, the Company funded its free cash flow deficit with
draws from the $500 million bank credit facility. Under its current business
plan, the Company estimates that, in addition to the cash and cash equivalents
on hand and remaining availability under the $500 million bank credit facility
as of June 30, 2001, a total of an additional approximately $500 million will be
required to fund the Company's capital expenditures, working capital
requirements, operating losses and pro rata investments in joint ventures from
July 1, 2001 through June 30, 2002, of which approximately $260 million will be
required through December 31, 2001. As of June 30, 2001, approximately $54,261
was available under the bank credit facility. To fund its projected short term
cash needs, as well as future deficits through mid-2002, the Company is
exploring additional sources of financing including additional bank or
institutional credit facilities and additional funding from Adelphia. There is
no assurance that the Company will obtain any additional short term or long term
funding or that the terms of any new financing would not be materially adverse
to the Company, or that the Company will not be required to consider further
revisions to its business plan, the sale of assets or other alternatives.

June 30, 2001 follows:

<FN>
(a) Earnings before interest, income taxes, depreciation and amortization,
   restructuring charges, other income/expense and non-cash stock compensation
   ("EBITDA") and similar measures of cash flow are commonly used in the
   telecommunications industry to analyze and compare telecommunications
   companies on the basis of operating performance, leverage, and liquidity.
   While EBITDA is not an alternative to operating income as an indicator of
   operating performance or an alternative to cash flows from operating
   activities as a measure of liquidity as defined by GAAP, and while EBITDA may
   not be comparable to other similarly titled measures of other companies,
   management of Adelphia Business Solutions believes that EBITDA is a
   meaningful measure of performance.

(a) Table 2 summarizes operating results before the allocation of corporate
   overhead for Adelphia Business Solutions' Original and Expansion Markets,
   which includes non-consolidated joint ventures, grouped by the year or years
   in which operations commenced. Operating results are presented before an
   allocation of corporate overhead for network operating control center,
   engineering and other administrative support functions totaling $14.4 million
   in the June 2001 quarter and $17.2 million in the March 2001 quarter and
   before a restructuring charge of $5 million in the March 2001 quarter.

(b) Earnings before interest, income taxes, depreciation and amortization,
   restructuring charges, other income/expense and noncash stock compensation
   ("EBITDA") and similar measures of cash flow are commonly used in the
   telecommunications industry to analyze and compare telecommunications
   companies on the basis of operating performance, leverage, and liquidity.
   While EBITDA is not an alternative indicator of operating performance or an
   alternative to cash flows from operating activities as a measure of liquidity
   as defined by GAAP, and while EBITDA may not be comparable to other similarly
   titled measure of other companies, management of Adelphia Business Solutions
   believes that EBITDA is a meaningful measure of performance.
