Omeros Responds to Misleading Announcement Concerning Settlement with Former CFO Richard J. Klein

Omeros Corporation

today is addressing misleading statements in a press release issued yesterday by Davis Wright Tremaine, the law firm representing Richard J. Klein, Omeros' former chief financial officer with whom Omeros recently settled a lawsuit regarding his employment with Omeros.  Omeros' reasoned decision to enter into the settlement agreement and focus on its business is explained in its Current Report on Form 8-K filed with the Securities and Exchange Commission on November 1, 2012.  The settlement involved the release of all parties' claims, including Mr. Klein's claim to all Davis Wright Tremaine fees incurred since 2009. Omeros' insurance carrier has agreed to advance payment of the settlement funds subject to a reservation of rights. Mr. Klein's employment with Omeros was terminated in January 2009. In September 2009, five days following Omeros' public filing of its intent to market its initial public offering, Thomas A. Lemly, partner at Davis Wright Tremaine, filed Mr. Klein's initial complaint alleging wrongful termination in retaliation for his whistleblow in connection with a grant awarded to Omeros by the National Institutes of Health (NIH).  Omeros flatly denies that its termination of Mr. Klein's employment was retaliatory.
