(Nasdaq: OPWV), one of the world’s leading software innovators enabling revenue-generating personalized services which converge the mobile and broadband experience, today announced that Ken Denman, a member of the Company’s Board of Directors since April 2004, has been appointed as Openwave’s chief executive officer effective November 12. Mr. Denman, who will continue as a member of the Openwave Board,recently served as chairman and CEO of iPass, Inc. (Nasdaq: IPAS), and succeeds Bruce Coleman, Openwave’s Interim CEO since April 2008.

“Ken is a proven leader with a record of turning around enterprises and guiding them towards profitability,” said Charles Levine, Openwave’s chairman of the board. “The Board has worked closely with Mr. Denman and we are confident he has the executive leadership skills and industry experience to increase our already dominant presence in leading wireless and wired broadband operators around the world, and to expand our footprint with leading edge mobile internet and integrated messaging products.”

Under Mr. Denman’s leadership, iPass moved from a dial-up internet connectivity platform to a growing broadband opportunity, leading to 200% revenue growth and a successful initial public offering in 2004. In 2001, when Denman joined, iPass was a single-product company that had never made a profit and faced entrenched competition in a mature market.

Mr. Denman’s career spans more than 20 years in the global telecommunications and IT industries.

He also was a board member of UK mobile operator One-to-One (now T-Mobile UK).
