SRA is a software and services company and a leading provider of software for 4G, WiMAX, mobile devices (smart/cell phones, PDA), Wi-Fi, and broadband & wireless security solutions. The company's investment in Proxim will aid in the continued development and marketing of Proxim's WiMAX and 4G wireless solutions for the carrier, service provider, government and enterprise markets.

SRA chose to invest in and partner with Proxim Wireless for the development of 4G products based on Proxim's long history of innovation in the broadband wireless access (BWA) market. The combined wireless hardware and software expertise of Proxim and SRA will help to advance the ongoing development of high-performance, cost-effective WiMAX and 4G wireless products, services and solutions for carriers, service providers, governments and enterprises of all sizes.

"At Proxim, we have a long history of developing broadband wireless access and backhaul solutions, and this investment will help us push even further into our target markets with an emphasis on 4G technologies," said Pankaj Manglik, President and CEO of Proxim Wireless. "SRA brings a wealth of wireless software solutions and services expertise, which will help round out our carrier, service provider, government and enterprise solutions portfolio worldwide."

"As one of the world's premier providers of wireless and mobile software solutions, we have extensive expertise in WiMAX and 4G wireless systems," said Dr. Rao Papolu, President at SRA OSS. "Proxim Wireless is a natural fit as a partner given their end-to-end broadband wireless portfolio. Not only are we excited about the combination of our two companies' technologies, but the combination of our collective worldwide carrier, enterprise and channel relationships will also be very beneficial."

B. Riley & Co., LLC served as the exclusive financial advisor to Proxim Wireless in connection with this private placement of securities.

Key Facts About Investment

• Proxim issued 2.5 million shares of its new Series A Convertible Preferred Stock and 1.25 million shares of its new Series B Non-Convertible Preferred Stock in a private placement all at $2.00 per share for total consideration of $7.5 million
• Of the total $7.5 million consideration, Proxim received gross cash proceeds of $6.25 million and $1.25 million of subordinated debt issued by Proxim in July 2008 was cancelled
• SRA purchased 1.25 million shares of the Series A stock and all 1.25 million shares of the Series B stock while existing investors purchased the remaining 1.25 million shares of the Series A stock
• Proxim has appointed one SRA designee to its board of directors and compensation committee
• Each share of Series A stock is initially convertible into 13 1/3 shares of Proxim's common stock (determined by dividing the $2.00 per share Series A purchase price by the $0.15 conversion price); the Series B stock is not convertible into Proxim's common stock
• Dividends accrue on the Series A stock at a rate of 7% per annum compounded quarterly (but only while the market price of Proxim's common stock is less than the $0.15 conversion price); dividends accrue on the Series B stock at a rate of 10% per annum compounded quarterly (but that dividend rate could be increased to 15% per annum in certain situations)
• In the case of most acquisition and liquidation situations, first the holders of the Series A stock and the Series B stock would receive their original investment plus accrued dividends and then the remaining proceeds would be distributed among the holders of the common stock (but if the proceeds remaining available for distribution after the Series A and Series B preferential return exceed $30 million, then those remaining proceeds are distributed pro rata among the holders of the common stock and the holders of the Series A stock on an as-converted basis)
• The holders of the Series A stock and Series B stock can request redemption of that stock after three years; Proxim can request redemption of that stock after four years
• Holders of the Series A stock will vote with the holders of the common stock as a single class on an as-converted basis; the Series B stock generally has no stockholder voting rights
