          ------    ------------

                    In a press release dated September 21, 1999, ICG
          Communications, Inc. ("ICG") announced that, based upon a
          September 16, 1999 arbitration decision by the California
          Public Utility Commission in a matter between Pacific Bell
          and MFS/WorldCom, ICG believes that its third quarter results
          of operations may include a provision of approximately $50
          million for potentially uncollectible receivables from
          tandem switching and common transport rate elements previously
          billed to Regional Bell Operating Companies ("RBOCs").  A
          copy of the press release is attached.
