                    CABOT CORPORATION ANNOUNCES RESOLUTION OF
                  CONTRACT DISPUTE WITH VISHAY INTERTECHNOLOGY

         BOSTON, MA - (June 6, 2002) - Cabot Corporation (NYSE: CBT) today
announced that it has resolved the pending legal dispute regarding its long-term
tantalum supply contracts with Vishay Intertechnology, Inc. (NYSE: VSH) and its
subsidiaries. In connection with the resolution of the dispute, the parties have
entered into amended supply agreements that confirm Vishay's obligation to
purchase tantalum products at regular intervals throughout the terms of the
contracts, beginning immediately. In addition, subject to certain conditions,
prices (starting in 2003) and volumes have been reduced, and the term of one of
the supply contracts has been extended for one year.

         "We are very pleased to have resolved this dispute without further
legal proceedings," said Kennett F. Burnes, Chairman and CEO of Cabot
Corporation. Mr. Burnes went on to say, "The amended contracts will continue to
provide substantial value to the Company while normalizing our commercial
relationship with a significant and valued customer. Under the revised
agreements, we currently expect this year's results from our Performance
Materials business to be in the same range as its 2001 results. We remain
optimistic about the stability of Cabot's tantalum business and are well
prepared to supply all our customers' needs as the electronics industry
recovers. While there is still some uncertainty, assuming that the industry
conditions remain the same or improve, the business should show significant
improvement, perhaps as much as 50%, from this level in fiscal 2003, although
likely not to the levels previously indicated."

         The Company's contract dispute with one other customer continues.
