A 15-year veteran of Amazon, Mr. Zumwalt was responsible for managing the company's cash, investments and debt financings, in addition to other finance-related duties. During his tenure, he led his team in raising short- and long-term financings in excess of $40 billion for Amazon.

"Literally down the street from Amazon is Omeros – I have followed the company for years and recognize what the Omeros team is building," said Mr. Zumwalt. "I am impressed by the company's cutting-edge science, remarkable pipeline and strong leadership. I know Greg well, understand his vision for Omeros and am confident that I can contribute significantly. It's exciting to join a company focused on improving patients' lives, and I am eager to help further the continued success of Omeros."

"We are excited to welcome Kurt to Omeros," stated Gregory A. Demopulos, M.D., chairman and chief executive officer of Omeros. "In his 15 years at Amazon, Kurt helped build one of the most successful companies in history and a world class treasury organization. His reputation and network of contacts throughout the financial world are stellar, and I know that he will play an important role in Omeros' ongoing growth as we prepare to commercialize the first of multiple products in our pipeline behind OMIDRIA. I look forward to working closely with Kurt to continue expanding our strategic financial relationships and capitalizing on growing business opportunities."

An avid tennis player, Mr. Zumwalt is on the board of directors of both the United States Tennis Association (USTA) and the USTA Foundation.
