Watkins-Johnson Sells High-Density Plasma Chemical Vapor Deposition Intellectual Property and Associated Hardware to Applied Materials.

PALO ALTO, Calif.--(BUSINESS WIRE)--March 31, 1999--WJ Semiconductor Equipment Group, Inc., a wholly owned subsidiary of Watkins-Johnson Company (NYSE:WJ), announced today that it has completed the sale of its high-density plasma chemical vapor deposition (HDPCVD) intellectual property assets plus associated inventory and hardware to Applied Materials, Inc. (Nasdaq:AMAT).

This sale will result in a second-quarter pre-tax gain of $9 million.

"This transaction underscores our commitment, announced on March 1, to pursue the sale of the company in its entirety or as separate businesses to maximize value for our shareowners," said W. Keith Kennedy, president and chief executive officer of Watkins-Johnson Company.

Kennedy also noted that earlier this month WJ announced a non-binding letter of intent regarding the sale of most of its Semiconductor Equipment Group (SEG) to Silicon Valley Group (Nasdaq:SVGI). The HDPCVD assets, a part of SEG, had been excluded from that letter of intent in order to permit WJ to pursue the sale of these assets separately.

Applied Materials, Inc. is a Fortune 500 global growth company and the world's largest supplier of wafer fabrication systems and services to the global semiconductor industry. Applied Materials' web site is www.appliedmaterials.com.

Watkins-Johnson Company specializes in two high-technology business areas.
