million in cash and stock and the assumption of substantially all of Stone &
Webster's liabilities shown on its March 31, 2000 balance sheet, standby letters
of credit, and its liabilities under a new credit facility from Jacobs entered
into on May 9, 2000 pursuant to which up to $50 million of credit is being made
available to enable Stone & Webster to operate its businesses until the asset
sale is consummated.

prospects for the combination of Stone & Webster with Jacobs and believe that
the synergies realized from the combined operations will benefit the

     The proposed transaction is subject to approval under the Hart-Scott-Rodino
Act, confirmation of the Stone & Webster's plan of reorganization by the U.S.
Bankruptcy Court, completion of due diligence by Jacobs, and other customary
