                       Coudersport, PA - February 14, 2001

      Adelphia Business Solutions, Inc. ("the Company") (NASDAQ NNM: ABIZ)
      announced today that it will make a rights offering to the record holders
      of its outstanding Class A and Class B Common Stock as of the close of
      business on February 19, 2001, which is the record date. The rights
      offering will involve the offer of approximately 53,772,548 shares of
      newly issued Class A Common Stock and approximately 52,715,788 shares of
      newly issued Class B Common Stock. Under the rights offering, the Company
      will distribute, at no cost to its stockholders, 1.5 non-transferable
      subscription rights for each share of common stock held by holders of its
      Class A and Class B Common Stock on the record date. Each whole right will
      entitle holders of Class A Common Stock or Class B Common Stock,
      respectively, to purchase one share of the same class of common stock at a
      subscription price of $7.28 per share. The rights offering will expire on
      March 19, 2001, the expiration date. No fractional rights will be issued.

      Adelphia Communications Corporation, the owner of approximately 59.4% of
      the Company's outstanding common stock, has advised the Company that it
      intends to exercise its subscription rights in full, and would thereby
      acquire approximately 63.3 million shares of common stock for
      approximately $461 million. The Company anticipates that the rights
      offering will commence, and that the prospectus and related offering
      materials will be mailed to stockholders, on or about February 20, 2001.
      The Company plans to use the proceeds of the rights offering to repay
      revolving credit borrowings and for other general corporate purposes.

      The rights offering will be made only by means of a prospectus, which will
      be available from American Stock Transfer & Trust Company, the
      subscription agent for the rights offering, by calling (800) 937-5449



      within the United States and by calling (718) 921-8200 outside of the
      United States. Subscription materials may also be obtained from American
      Stock Transfer & Trust Company, which is located at 59 Maiden Lane, Plaza
      Level, New York, NY 10038.

      This press release shall not constitute an offer to sell or the
      solicitation of an offer to buy nor shall there be any sale of the Class A
      Common Stock or the Class B Common Stock in any State in which such offer,
      solicitation or sale would be unlawful prior to registration or
      qualification under the securities laws of any such State.
