SPARKS, Nev., Dec. 2, 2004 – SulphCo, Inc. (OTC Bulletin Board: SLPH), a leader in developing and marketing high-powered ultrasound technology and equipment for the petroleum industry, announced today that Dick Masica, formerly president of Texaco Chemical Inc., has joined the company’s board.

Masica presently serves as an advisor to SulphCo. SulphCo has developed patented ultrasound technology to remove sulfur from crude oil that produces more usable oil per barrel. Based on current tests, the company’s ultrasound process, which alters the molecular structure of oil, results in additional usable gallons per barrel of crude.

SulphCo has a collaboration agreement with Chevron Texaco Technology Co., a unit of ChevronTexaco Corp., to expedite commercialization of the technology. Masica served as president of Texaco Chemical, Inc. from 1994 to 1997. During his 39-year career at Texaco, now ChevronTexaco, he also held the position of vice president-business management of Texaco Chemical Company. Masica has participated in a leadership role in two major divestitures, as well as other domestic and foreign reorganizations, mergers and startups. He fills the seat vacated by Kirk Schumacher, president of SulphCo, in a move to create a more balanced board of directors for the company.

“Dick’s expertise, counsel and respected track record in the industry will be extremely helpful in guiding our efforts as we continue to bring our technology to market,” said Rudolf Gunnerman, SulphCo chairman and chief executive officer.
