            ADELPHIA BUSINESS SOLUTIONS, INC ANNOUNCES FIRST QUARTER
                              RESULTS OF OPERATIONS


                         Coudersport, PA - May 14, 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 first quarter which
ended on March 31, 2001. First quarter results saw record levels of consolidated
operating revenues of $110.3 million. Net loss applicable to common stockholders
for the first quarter totaled $103.0 million, or $1.33 per share, compared with
$58.8 million, or $0.85 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 59% to $110.3
million in the March 2001 quarter, from $69.3 million in the March 2000 quarter
and were at approximately the same level as the December 2000 quarter.
Consolidated revenues were comprised of voice revenue (includes local,
long-distance and other revenues) of $87.5 million in the March 2001 quarter as
compared with $57.0 million in the March 2000 quarter and data revenue (includes
internet, dedicated access and data services) of $22.8 million in the March 2001
quarter as compared with $12.3 million in the March 2000 quarter. Average
revenue per installed access line in the March 2001 quarter was approximately
$49 per month, in line with $50 per month in the prior quarter. Consolidated
revenues in the March 2001 quarter included $10.8 million of reciprocal
compensation revenue, or 9.8% of revenues. The Company expects calendar 2001
revenues to be approximately $485 million to $500 million, with second quarter
2001 revenues slightly higher than the March 2001 quarter. As a result of
continued revenue growth combined with cost reduction efforts associated with
the revised business plan, the Company expects EBITDA losses to decrease to
approximately $10 million for the second quarter of calendar 2001 and to
approximately $20 million for the full year of calendar 2001.







Consolidated gross margin as a percent of sales was 44.9% in the March 2001
quarter as compared with 47.6% of sales in the December 2000 quarter. Gross
margins were somewhat lower in the current quarter as the Company continues to
review non-paying customers, and where necessary, disconnect customers from its
networks. The Company expects gross margin as a percent of sales will improve
during the second quarter and throughout the remainder of calendar 2001.
Consolidated EBITDA losses for the March 2001 quarter were better than expected
at $15.3 million versus a $34.2 million EBITDA loss for the December 2000
quarter. The Company achieved its goal of reducing selling, general and
administrative costs associated with previous market expansion efforts, as well
as controlling other discretionary spending.

In addition to the Company's EBITDA loss for the March 2001 quarter, the Company
recorded a restructuring charge totaling $5.0 million comprised primarily of
direct costs associated with the previously announced revision of the Company's
business plan from 200 markets to its current 80 market business plan and
severance costs associated with the related layoff of approximately 210
employees in January 2001.

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
5.8% in the March 2001 quarter and gross margin as a percentage of sales of
70.9%. Revenue for the Class of 1996 markets increased 39.6% as compared with
the March 2000 quarter, with gross margins in excess of 70.0% of revenues for
each of the past six quarters. As such, EBITDA for these markets before
allocation of corporate overhead increased 64.5% from an annualized $79.4
million for the March 2000 quarter to an annualized $130.6 million for the March
2001 quarter. Furthermore, from the March 2000 quarter to the March 2001
quarter, the eight Class of 1997/1998 markets' revenues increased 73.6% from
$9.4 million to $16.3 million. Gross margins for these markets increased 145.1%
during the same period and annualized EBITDA before allocation of corporate
overhead increased from $(0.4) million to $19.5 million, or to 29.9% of revenues
in the March 2001 quarter.

The Class of 1999 markets also contributed to the Company's improved financial
performance with revenue growth of 112.7% as compared to the March 2000 quarter.
Furthermore, EBITDA losses before allocation of corporate overhead decreased to
$23.8 million for the March 2001 quarter compared to $26.6 million in the
December 2000 quarter. The Class of 2000 markets also had EBITDA losses before
allocation of corporate overhead which decreased from $6.4 million in the
December 2000 quarter to $4.3 million in the March 2001 quarter. As such, in the
March 2001 quarter, each of the Company's Class market groupings demonstrated
improved EBITDA performance for the first time, with overall EBITDA before
allocation of corporate overhead of positive $9.4 million as compared to
positive $1.4 million in the December 2000 quarter.

Days sales outstanding in accounts receivable increased somewhat to 83 days as
of March 31, 2001 from 78 days at December 31, 2000. The Company expects days
sales outstanding to decrease to the mid-seventies by June 30, 2001.

During the March 2001 quarter, the Company and its consolidated subsidiaries
invested approximately $136.3 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
$470-$500 million. As of March 31, 2001, total gross property, plant and
equipment of the Company and its consolidated subsidiaries, was approximately
$1.9 billion. The Company's condensed consolidated balance sheets are attached
on Table 3.

During the March 2001 quarter, the Company funded its free cash flow deficit
with draws from the proceeds from a common stock rights offering. Proceeds from
the rights offering not needed to fund the quarter's free cash flow deficit were
used to pay down the Company's bank credit facility. The Company expects to fund
its projected future deficits through mid-2002 through a combination of
additional draws under the credit facility and additional bank or institutional
indebtedness.

(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.

    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.
