Transdimension closes $18 MILLION in new funding

IRVINE, Calif., July 1, 2004 - TransDimension, a leading provider of USB connectivity solutions for embedded applications, announced that it has completed its Series C and Series D financings raising a total of $18.35 million. San Bruno, Calif.-based VantagePoint Venture Partners led the Series D financing, with participation by iSherpa Capital. The Series C financing was led by GKM Ventures with participation by VantagePoint Venture Partners, iSherpa Capital, Rolling Oaks Capital, and Shelter Capital Partners.

Proceeds from the financing were used in part to acquire the assets of the ARC International Peripheral Connectivity business including the ARC USB and Ethernet IP cores, CertiPHY capability and USB system support and development tools (see TransDimension/ARC announcement, issued at 8:00 AM PST, July 1, 2004). The acquisition will enable TransDimension to expand its wired USB product base by leveraging the ARC USB IP cores and to further develop the company's peripheral connectivity focus into wireless USB used in high-volume consumer electronic devices. In addition, the financing provides TransDimension with expansion capital to introduce new technology to the market and accelerate its international marketing focus.

"The consumer electronics device market continues to grow at a steady pace. TransDimension's strength is in its ability to offer solutions that address the pent up demand for direct connectivity between these devices," said Melissa Crane Guzy, managing director, VantagePoint Venture Partners. "We are pleased to lead this strategic round of funding that enables the company to continue to grow and lead the industry in connectivity solutions."

The funding news comes on the heels of TransDimension's recent announcements that it has shipped its five millionth embedded USB host controller and that it recently secured customer wins with NEC Electronics Corporation and STMicroelectronics. TransDimension also recently announced that it has joined the WiMedia Alliance, an industry alliance focused on Ultra Wideband (UWB) wireless connectivity.

TransDimension's product lines include ICs (semiconductors), USB function blocks for integration into larger system-on-chip solutions and software that provide direct connectivity for a wide range of PC peripheral, consumer and mobile devices that until now have required an indirect means, such as a PC host, to exchange data. These embedded applications include cellular phones, set top boxes, printers, PDAs, digital cameras, portable storage products and CD, DVD and MP3 players.

"This funding is validation that our commitment to USB connectivity for consumer electronics devices is on target," said Rick Goerner, CEO of TransDimension. "The additional capital has enabled our acquisition of ARC's assets, which in turn has expanded our market leading USB software, semiconductor and IP capability with proven, high speed USB cores. I look forward to the assistance of our new and existing investment partners as we continue to develop future business and advance our strategy to wireless connectivity solutions."
