Electronic Sensor Technology Appoints Former Northrop Grumman Exec to Chair Its Board

Electronic Sensor Technology, Inc. has appointed former Northrop Grumman TASC President James H. Frey to the position of Chairman of the Board of Directors. Prior to Northrop Grumman, Mr. Frey served as Senior Vice President, Group Executive for the Litton Information Systems Group until Northrop Grumman's purchase of Litton in April 2001. In this position, he led the $1.4 billion group of Litton businesses involved in information technology services. Prior to joining Litton, he held various positions at General Electric including General Manager, Spacecraft Operations.

Since his retirement from Northrop Grumman TASC in March 2002, Frey has served on the Advisory Board for the National Geospatial Intelligence Agency (NGA) and IDELIX Software, Inc., and on special panels supporting the management of the National Reconnaissance Office (NRO) and the Director of Central Intelligence (DCI). In his role as Chairman, Frey will assist the Company in accelerating the adoption of zNose -- an electronic nose capable of rapid detection of threats and illegal compounds utilizing a patented vapor analysis technology.

"I am delighted to welcome somebody of Jim's stature to such a key role for our Company," said Edward J. Staples, Electronic Sensor Technology's Chief Executive Officer. "zNose has already been sold in approximately 30 countries worldwide to clients such as the United States Army, Navy, Air Force, Marines, Northrop Grumman, Lockheed Martin, Honeywell Corporation and SC Johnson. I am confident that Jim's extensive relationships and experience working with large industrial concerns will help us penetrate these important customers and expand relationships with existing ones."

"I am excited to join Electronic Sensor Technology," said Frey. "zNose has the potential to play an important role in helping to secure the country through its unique ability to provide comprehensive, real time analysis of any chemical vapor with part-per-trillion sensitivity. I look forward to working with Ed and his team to raise the profile of this exciting technology."
