Arrowhead Appoints Virginia Dadey as Vice President, Investor Relations

PASADENA, Calif. — Arrowhead Research Corporation (Nasdaq:ARWR) today announced the appointment of Virginia Dadey as its Vice President, Investor Relations. Ms. Dadey has fifteen years of experience in financial markets as an investment specialist and will function as Arrowhead’s nanotech investor point person. Ms. Dadey will be based in New York City, where she will call on her years of experience in institutional sales to build Arrowhead’s shareholder base and to improve shareholder liquidity.

“Arrowhead is very fortunate to attract a Vice President with Virginia’s particular combination of skills,” said R. Bruce Stewart, Arrowhead’s President. “She has a successful track record in nanotech deal-making, can call on a wide network of domestic and international analysts and fund managers, plus she can speak with authority about nanotechnology as an investment.”

“I can’t think of anybody better qualified to present Arrowhead’s unique nanotech business model to the investment community.”

Dadey, who previously worked for the Maxim Group as Senior Vice President for institutional sales, praised Arrowhead’s “extremely compelling” business model. “Arrowhead is an innovator in developing and executing in the nanotech field.”

“I believe this business sector has a bright future. I am very excited about joining the Arrowhead team which has been able to bridge the gap between the laboratory, where full research can be done, and the public markets without having to go through the large costs associated with the traditional venture capital model,” Dadey said.

Dadey worked for the Maxim Group and its predecessor company, Investec, since 2001. Prior to working for Maxim Group, she was a vice president at Gruntal & Co. from 1996 to 2001. She received her B.S. from Purdue University.

About Arrowhead Research Corporation

Currently, Arrowhead is supporting efforts in stem cell technology, nanomaterials, nanoelectronics, and nanobiotools at the California Institute of Technology and Stanford University.

–Commercialization Program: After prototypes have been sufficiently developed in the laboratories, Arrowhead forms or acquires majority-owned subsidiaries to commercialize the technology and provides the subsidiaries with strategic, managerial, and operational support. At present, Arrowhead owns majority interest in subsidiaries commercializing diverse technologies, including anti-cancer drugs, RNAi therapeutics, and compound semiconductor materials.

–The Patent Toolbox: Arrowhead has acquired or exclusively licensed patents and patent applications covering a broad range of nanotechnology. The Company is actively seeking to add to this intellectual property portfolio.
