RAE Systems Wins Polimaster Arbitration

San Jose, Calif. — July 13, 2007 — RAE Systems Inc. (AMEX: RAE), a leading global provider of rapidly deployable sensor networks that enable customers to identify safety and security threats in real time, today announced it prevailed in its arbitration with Polimaster Ltd. In an Interim Award, the arbitrator ruled among other things that:

(i)	Polimaster failed to prove its claims and is not entitled to relief;
(ii)	RAE Systems has proven its counter claims and is awarded damages of approximately $2.4 million; and
(iii)	RAE Systems as the prevailing party may file an application for attorney’s fees and costs.

Further determinations regarding whether the arbitrator’s factual findings should be treated as confidential and RAE Systems’ application for attorney’s fees and costs will be included in a Final Award, which will also incorporate the contents of the Interim Award.

“We always believed Polimaster’s claim was without merit, and we are gratified the arbitration proceeding has confirmed our position,” said Robert Chen, president and chief executive officer. “With the resolution of this case, we believe the company has a clear path to drive greater success of our radiation products worldwide.”

As previously announced, RAE Systems and Polimaster had been involved in an arbitration proceeding conducted under the auspices of Judicial Arbitration and Mediation Services, Inc. in California. Although RAE Systems has been awarded damages and may also be awarded attorneys fees and costs, at this time the company is unable to determine whether it will be able to collect on any such awards due to uncertainties pertaining to Polimaster’s financial position and other factors.
