FOR IMMEDIATE RELEASE:


      ADELPHIA BUSINESS SOLUTIONS ANNOUNCES SIGNIFICANT CAPITAL SPENDING
 REDUCTIONS, $125 MILLION PLANNED ASSET SALES TO ADELPHIA COMMUNICATIONS, ITS
                PARENT COMPANY, AND REVISED FINANCIAL GUIDANCE

- -  Company announces capital spending reductions of $210 million through 2002
   with additional annual capital spending reductions of $120 million per year
   thereafter;

- -  Adelphia expected to buy $125 million in CLEC assets during 2001;

- -  Company estimates reduction in unfunded free cash flow deficit to a pro forma
   range of $80 million to $280 million for period 7/01/01 through 12/31/03.

                       Coudersport, PA - September 5, 2001

John J. Rigas, Chairman of Adelphia Communications Corporation ('Adelphia')
(NASDAQ NNM: ADLAC) and Adelphia Business Solutions, Inc. ('ABS') (NASDAQ NNM:
ABIZ) announced today revised guidance based on several changes to the ABS
business plan. Mr. Rigas announced that ABS will further reduce capital
spending. ABS is now planning to reduce capital spending for the remainder of
2001 by $25 million, during 2002 from $420 million to $235 million and during
2003 and thereafter from $320 million per year to $200 million per year. The
planned reduction in capital spending results from decreased spending on long

haul fiber, eliminating further investment in approximately 10 of its markets
and redeploying existing assets in those markets to its other markets,
reductions in the further expansion of local fiber rings, decreases in prices
for equipment purchases and the impact of the sale of assets to Adelphia. Table
1 details these reductions:

                               =================================



Mr. Rigas also announced that ABS and Adelphia intend to complete sales by ABS
of $125 million of assets to Adelphia. These sales will be subject to definitive
documentation and the receipt of a fairness opinion by the Board of Directors of
ABS. The companies expect to complete these sales by or shortly after September
30, 2001.

Mr. Rigas commented "We believe that the ABS facilities based business plan is
substantially differentiated from the broad category of CLECs generally. Even
with the planned reductions, we also believe Adelphia Business Solutions has
more local fiber deployed in the aggregate than virtually any non-incumbent LEC,
which we continue to feel is a significant competitive advantage as compared to
other CLECs.

It is also fortunate that virtually all of our core infrastructure capital has
been deployed in the markets in which we are proceeding and that the capital
spending savings associated with our new business plan are for activities that
were not expected to generate meaningful EBITDA until after 2003. Furthermore,
ABS now expects to be free cash flow positive in the first half of 2004. These
cuts, combined with the $125 million to be raised from the announced asset sales
plus the expected completion of a $300 million to $500 million bank credit
facility will cut our previously expected unfunded free cash flow deficit from
June 30, 2001 through the end of 2003 from approximately $1.1 billion to
approximately $80 million to $280 million. We expect our continued success in
increasing EBITDA will allow us to secure additional funding during 2002, either
through additional assets sales or bank debt to finance the remaining unfunded
deficit."
