UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

On July 11, 2006, RAE Systems Inc. (“RAE”) purchased the assets of Aegison Corporation (“Aegison”), a Santa Clara, California based supplier of fixed and mobile digital video surveillance systems, for $2.1 million in cash (the “Transaction”).

The following unaudited pro forma condensed combined financial statements are based on the historical financial statements of RAE and Aegison. The unaudited pro forma condensed combined balance sheet as of June 30, 2006 (the “Pro Forma Balance Sheet”) was prepared by combining RAE’s consolidated balance sheet as of June 30, 2006 with Aegison’s consolidated balance sheet as of June 30, 2006, with the assumption that the Transaction had occurred as of June 30, 2006.

The following unaudited pro forma condensed combined statement of operations for the six months ended June 30, 2006 and for the year ended December 31, 2005 (together the “Pro Forma Statements of Operations”), have been prepared by combining RAE’s consolidated statement of operations for the six months ended June 30, 2006 and fiscal year ended December 31, 2005 with Aegison’s corresponding consolidated statement of operations for the six months ended June 30, 2006 and fiscal year ended December 31, 2005. The Pro Forma Statements of Operations give effect to the Transaction as if it had occurred at the beginning as of January 1, 2005 or January 1, 2006, respectively. Neither the Pro Forma Statements of Operations nor the Pro Forma Balance Sheet reflects the anticipated cost savings or revenue enhancements in connection with the Transaction.  

The Pro Forma Statements of Operations and the Pro Forma Balance Sheet are presented for illustrative purposes only. It is not necessarily indicative of the operating results or financial position that would have occurred if the Transaction had been consummated at the beginning of the period indicated, nor is such information indicative of the future operating results or financial position of RAE Systems Inc. after the acquisition.
