                   ADELPHIA BUSINESS SOLUTIONS, INC. COMMENCES
             VOLUNTARY CASE UNDER CHAPTER 11 OF THE BANKRUPTCY CODE

              $135 Million Debtor-In-Possession Financing Expected

                        Coudersport, PA - March 27, 2002

Adelphia Business Solutions, Inc. ("ABS") (Nasdaq: ABIZ) announced today that
ABS and certain of its wholly-owned subsidiaries have commenced voluntary cases
under chapter 11 of the Bankruptcy Code in the U.S. Bankruptcy Court for the
Southern District of New York.

ABS also announced that it has reached an agreement with Adelphia Communications
Corporation and a Rigas family affiliate to provide debtor-in-possession (DIP)
financing in the aggregate principal amount of up to $135 million. This DIP
financing will provide an immediate source of funds to ABS, enabling it to
satisfy the customary obligations associated with the daily operation of its
business, including the timely payment of new inventory shipments, employee
wages and other obligations. The DIP financing is subject to approval of the
Bankruptcy Court.

ABS is engaged in advanced negotiations with the holders of its 12-1/4% Senior
Secured Notes due 2004 regarding the treatment of their claims. Any resolution
of these negotiations will also be subject to approval of the Bankruptcy Court.

In commencing these chapter 11 cases, ABS concluded that a financial
restructuring, which could best be achieved through the chapter 11 process, was
the most viable alternative for resolving its financial difficulties, given its
capital requirements and debt service obligations. ABS voluntarily commenced
these cases as a result of the virtual shutdown of the telecommunications
capital markets and the decline in the telecommunications industry generally.

Adelphia Business Solutions, Inc. provides integrated communications services to
business customers through its fiber optic communications network.
