          ADELPHIA BUSINESS SOLUTIONS, INC ANNOUNCES THIRD QUARTER
                              RESULTS OF OPERATIONS


                       Coudersport, PA - November 12, 2001




Adelphia Business Solutions, Inc. ("the Company") (NASDAQ: ABIZ) reported
results of operations for the Company for the third quarter which ended on
September 30, 2001. Third quarter results saw consolidated operating revenues of
$116.3 million. Net loss applicable to common stockholders for the third quarter
totaled $114.9 million, or $0.85 per share, compared with $75.8 million, or
$1.08 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 24% to $116.3
million in the September 2001 quarter, from $93.6 million in the September 2000
quarter and were relatively flat with the June 2001 quarter. Consolidated
revenues were comprised of voice revenue (includes local, long-distance and
other revenues) of $86.8 million in the September 2001 quarter as compared with
$76.3 million in the September 2000 quarter and data revenue (includes internet,
dedicated access and data services) of $29.5 million in the September 2001
quarter as compared with $17.3 million in the September 2000 quarter. Average
revenue per installed access line in the September 2001 quarter was
approximately $49 per month, or the same as the prior quarter. Consolidated
revenues in the September 2001 quarter included $11.4 million of reciprocal
compensation revenue, or 9.8% of revenues. The Company expects reciprocal
compensation revenues going forward to decrease by approximately 50% to 70% as a
result of the FCCs recent ruling.




Consolidated gross margin as a percent of sales was 52.9% in the September 2001
quarter as compared with 47.0% of sales in the June 2001 quarter. Consolidated
EBITDA losses for the September 2001 quarter were slightly higher than Company
expectations at $5.3 million versus a $8.7 million EBITDA loss for the June 2001
quarter. While overall higher gross margins contributed positively to the
current quarter's financial results, increased bad debts contributed to the
slightly higher than expected EBITDA losses.

As shown in Table 2, the Company's thirteen Class of 1996 markets had gross
margin as a percentage of sales of 74.5%. Revenue for the Class of 1996 markets
increased 14.3% as compared with the September 2000 quarter, with gross margins
in excess of 70.0% of revenues for each of the past eight quarters. As such,
EBITDA for these markets before allocation of corporate overhead increased 35.2%
from an annualized $106.7 million for the September 2000 quarter to an
annualized $144.2 million for the September 2001 quarter. Furthermore, from the
September 2000 quarter to the September 2001 quarter, the eight Class of
1997/1998 markets' revenues increased 44.9% from $14.1 million to $20.4 million.
Gross margins for these markets increased 100.8% or from $7.5 million to $15.0
million, from the September 2000 quarter to the September 2001 quarter and
EBITDA before allocation of corporate overhead increased from $10.3 million to
$32.7 million on an annualized basis and to 40.2% of revenues in the 2001
quarter.

The Class of 1999 markets also contributed to the Company's improved financial
performance with revenue growth of 33.5% in the September 2001 quarter as
compared to the September 2000 quarter. Gross margins in the September 2001
quarter also improved by $3.3 million when compared to the June 2001 quarter, to
a positive $0.7 million 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 $17.7 million
for the September 2001 quarter compared to $21.8 million in the June 2001
quarter. The Class of 2000 markets had EBITDA losses before allocation of
corporate overhead of $4.8 million in the September 2001 quarter, about $0.6
million higher than the June 2001 quarter. Overall EBITDA before allocation of
corporate overhead was positive $21.7 million, a 19.2% improvement, compared to
positive $18.2 million in the June 2001 quarter. In addition, the September 2001
quarter with positive combined EBITDA after corporate overhead of approximately
$7.0 million represented the second consecutive quarter in which the Company's
combined financial performance of all of its class markets after corporate
overhead resulted in positive EBITDA.

Days sales outstanding in accounts receivable increased to 89 days as of
September 30, 2001 as compared with 84 days at June 30, 2001 due primarily to
slow payment from the ILECs for reciprocal compensation. As of September 30,
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 September 2001 quarter, the Company and its consolidated subsidiaries
invested approximately $113.4 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.

On October 1, 2001, subsidiaries of the Company sold certain network and
telecommunication assets to subsidiaries of Adelphia Communications Corporation
("Adelphia") (NASDAQ: ADLAC) for approximately $141 million in cash and the
assumption of approximately $9.0 million in liabilities. After excluding the
results of the networks associated with the asset sales, the Company would have
had revenues and an EBITDA loss on a consolidated basis of $104.3 million and
$9.9 million, respectively, for the September 2001 quarter. As the network and
telecommunication assets sold to Adelphia constitute businesses contained within
separate legal entities under common control, the sales will be reported as a
change in reporting entity. As a result, the Company expects to be recasting its
financial statements for the year ended December 31, 2001 to reflect these asset
sales for all applicable periods that the network and telecommunication assets
were under the common control of Adelphia. After giving effect to these asset
sales, the Company expects consolidated revenue and positive EBITDA for the
quarter ended December 31, 2001 to be approximately $115 to $120 million and
approximately $2 to $5 million, respectively. Unless otherwise stated, all
historical amounts presented in this press release for the periods ending on or
before September 30, 2001 include results for the assets sold to Adelphia on
October 1, 2001.

During the September 2001 quarter, the Company funded its free cash flow deficit
with draws from the $500 million bank credit facility as well as deposits made
on sales of certain assets to Adelphia. Under its current business plan, the



Company estimates that a total of approximately $395 million will be required to
fund the Company's capital expenditures, working capital requirements, operating
losses and pro rata investments in joint ventures from October 1, 2001 through
September 30, 2002, of which approximately $85 million will be required through
December 31, 2001. As of September 30, 2001, approximately $5.9 million was
available under the bank credit facility with approximately $19.4 million in
cash on hand, including restricted cash, and on October 1, 2001 an additional
$80.0 million in cash was paid by Adelphia to close its purchase of network
assets from the Company. The Company believes it has the resources to meet its
funding requirements for the quarter ending December 31, 2001. To fund its
projected future deficits, the Company is exploring additional sources of
financing. The Company currently does not expect to obtain the additional $300
to $500 million bank credit facility previously discussed. 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, additional sales of assets or other alternatives if
necessary funding is not obtained.

On November 9, 2001, Adelphia announced that its Board of Directors had
authorized in principle the distribution of Adelphia's 79% common equity
interest in the Company to the common stockholders of Adelphia, that the
spin-off of Adelphia's equity interests was expected to occur no later than
March 31, 2002, and that in connection with the spin-off Adelphia may provide up
to $100 million of additional credit support to the Company's subsidiaries.

<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 $14.8
    million in the September 2001 quarter and $14.4 million in the June 2001
    quarter. Amounts presented include results for the networks sold to Adelphia
    on October 1, 2001.
(b) Earnings before interest, income taxes, depreciation and amortization,
    restructuring charges, other income/expense and noncash stock compensation

    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.
