          The following information was included in a press release issued by

          IT and OHM, an Ohio corporation ("OHM"), announced March 4, 1998, that
the OHM Board of Directors has been reconstituted in accordance with the terms
of the Agreement and Plan of Merger, dated as of January 15, 1998, among IT, OHM
and IT-Ohio, Inc., a subsidiary of IT, (the "Merger Agreement") pursuant to
which IT is acquiring OHM in a two-step transaction comprised of a cash tender
offer and a merger.  IT-Ohio consummated its cash tender offer for OHM common
stock on February 25, 1998, and acquired 13,933,000 shares in the tender offer.
As a result of the tender offer and the concurrent repurchase by OHM of
approximately 2,535,000 shares of OHM common stock from a principal
shareholder, in accordance with the terms of the Second Amended and Restated
Share Repurchase Agreement, dated as of February 17, 1998, among OHM, Waste
Management, Inc., a Delaware corporation, Rust International Inc., a Delaware
corporation, Rust Remedial Services Holding Company Inc., a Delaware
corporation, and IT (the "Share Repurchase Agreement"), IT now owns
approximately 54% of the outstanding shares of OHM stock.  IT intends to
complete the merger of IT-Ohio into OHM shortly in accordance with the terms of
the Merger Agreement.

          Pursuant to the Merger Agreement, the OHM Board now consists of five
members, three of whom are representatives of IT and two of whom are continuing
directors of OHM.  Messrs. Anthony J. DeLuca, Daniel A.

                                      -2-

 
D'Aniello and Philip B. Dolan have been appointed to the OHM Board as IT
representatives. Messrs. Richard W. Pogue and Charles W. Schmidt remain on the
OHM Board as well. In conjunction with the Board change, Mr. DeLuca was
appointed as chairman of the board, president and chief executive officer of
OHM.

          The preceding is qualified in its entirety by reference to the Merger
Agreement, the Share Repurchase Agreement and the Press Release, which have been
filed as exhibits hereto and the first two of which are incorporated by
