clinical-stage biopharmaceutical company committed to discovering, developing
and commercializing products targeting inflammation, coagulopathies and

Jacobsen is joining the company as vice president, finance and chief
accounting officer.

"Mike's experience leading finance teams responsible for the commercial launch
of biopharmaceutical products including Cialis^®, one of the most successful
drugs on the market, will be instrumental as we anticipate marketing approval
for OMS302 next year," stated Gregory A. Demopulos, M.D., Omeros' chairman and
chief executive officer. "With his deep background in accounting, business
management and finance, I expect that Mike will begin contributing immediately
to Omeros' planned transition to a commercial company."

"I am impressed by what the Omeros team has accomplished and by the tremendous
potential of Omeros' development programs," said Mr. Jacobsen. "These are
exciting times for Omeros, and I look forward to helping the company achieve
commercial success for a long line of products, starting with OMS302."

Mr. Jacobsen brings over 30 years of senior business management and accounting
experience to Omeros and led the finance teams responsible for the commercial
launch of Cialis® and Recothrom^®. His experience includes more than a decade
of service as a senior finance and accounting officer with publicly traded
medical research, drug development and biotechnology companies. Omeros' board
of directors will appoint Mr. Jacobsen to his position of vice president,
finance and chief accounting officer.

Most recently, Mr. Jacobsen was vice president of finance and chief accounting
officer of Sarepta Therapeutics, Inc. (formerly AVI BioPharma, Inc.). From
