Item 8.01. Other Events.

     The following are updates to certain of the legal proceedings described in Note 5 to the RAE Systems Inc. (the “Company”) consolidated condensed financial statements, Commitments and Contingencies, which is incorporated by reference into the Company’s Quarterly Report on Form 10-Q for the quarter ended March 31, 2007.

     Polimaster Ltd. (“Polimaster”) filed a complaint against the Company on May 9, 2005, in the United States District Court for the Northern District of California in a case styled Polimaster Ltd. v. RAE Systems Inc. (Case No. 05-CV-01887-JF). The complaint alleged, among other things, that the Company breached its contract with Polimaster and infringed upon Polimaster’s intellectual property rights. Polimaster moved for a preliminary injunction on June 17, 2005. The Court denied Polimaster’s request on September 6, 2005. The dispute was subject to a contractual arbitration agreement, although the federal court retained jurisdiction over the matter pending arbitration by the parties.

     Arbitration was formally commenced on June 12, 2006 for the Polimaster matter. Polimaster’s Demand for Arbitration asserted damages totaling $13.2 million and sought an injunction against sales of the Company’s Gamma Rae II and Neutron RAE II radiation detection products. The Company asserted counterclaims against Polimaster for breach of contract and tortuous interference with contract, among other things, and sought monetary damages of its own. A ten day arbitration proceeding was completed on March 16, 2007. The arbitration was conducted under the auspices of Judicial Arbitration and Mediation Services, Inc. (JAMS) in California. The parties filed post hearing briefs in May 2007.

     On July 13, 2007, the Company issued a press release announcing the decision of arbitrator in connection with the Polimaster matter. A copy of the Company’s press release is attached hereto as Exhibit 99.1 and incorporated herein by reference.
