Arrowhead Subsidiary, Unidym, Inc., Appoints Semiconductor Industry Executive as Chief Executive Officer.

PASADENA, Calif. -- Arrowhead Research Corporation (NASDAQ:ARWR), announced today that Arthur L. Swift has been appointed Chief Executive Officer & President of its majority-owned subsidiary, Unidym, Inc., a leader in the development and manufacture of carbon nanotubes for applications in the electronics industry. Unidym, which recently merged with Carbon Nanotechnologies, Incorporated (CNI), possesses a foundational patent portfolio that covers nearly every aspect of carbon nanotube manufacturing and processing.

"Art has a track record of success in selling and licensing new products and technologies to electronics manufacturers," said R. Bruce Stewart, Arrowhead's CEO & Chairman. "His depth and breadth of executive, technical, and marketing experience in the industry will be of enormous benefit to Unidym as it executes its business plans."

"I expect Unidym to transform several potentially high volume applications within the electronics industry," commented Swift. "Unidym's technology likely will enable more robust touch screens, lower cost flat panel displays, more efficient thin-film solar cells, and may even make flexible electronics truly practical. Plus, the company's IP portfolio provides licensing opportunities as well as considerable barriers to any future competition. I'm excited to have the opportunity to contribute to Unidym's success."

Mr. Swift comes to Unidym from Transmeta Corporation, an innovative semiconductor company in the Silicon Valley, where he most recently held the position of President and Chief Executive Officer. Prior to his promotion to CEO, he was Senior Vice President of Marketing. At Transmeta, Mr. Swift was instrumental in transforming the company's strategy from selling semiconductor chips to developing and licensing intellectual property, a change that nearly doubled Transmeta's revenue in the first two years after the strategy shift.

Prior to Transmeta, Art held senior leadership roles ranging from President and Chief Operating Officer at an embedded software startup, Lynuxworks, to Vice President and General Manager at a variety of large divisions of the established chip-maker Cirrus Logic. Art has also held senior marketing and engineering positions with Summit Microelectronics, Sun Microsystems, Digital Equipment, and Fairchild Semiconductor.

Mr. Swift earned a B.S. in Electrical Engineering at the Pennsylvania State University.
