Ladies and Gentlemen:

We have acted as special counsel to Omeros Corporation, a Washington corporation (the “Company”), in connection with the registration by the Company under the Securities Act of 1933, as amended (the “Securities Act”), of the offer and sale from time to time of up to $100,000,000 in aggregate amount of (i) shares of the Company’s common stock, par value $0.01 per share (the “Common Stock”), (ii) shares of the Company’s preferred stock, par value $0.01 per share (the “Preferred Stock”), (iii) debt securities, which may be either senior or subordinated and may be issued in one or more series (the “Debt Securities”), (iv) depositary shares, representing a fractional interest in a share of Preferred Stock and evidenced by a depositary receipt (the “Depositary Shares”), (v) warrants to purchase Common Stock, Preferred Stock or Debt Securities (the “Warrants”), (vi) rights to subscribe for and to purchase Common Stock or Preferred Stock (the “Subscription Rights”) and (vii) units comprised of any combination of Common Stock, Preferred Stock, Debt Securities, Depositary Shares, Warrants or Subscription Rights (“Units” and, collectively with Debt Securities, Depositary Shares, Warrants and Subscription Rights, the “Covered Securities”), pursuant to the Company’s Registration Statement on Form S-3, File No. 333-219959 (the “Initial Registration Statement”) filed with the Securities and Exchange Commission (the “Commission”) on August 14, 2017, and Post-Effective Amendment No. 1 thereto (“Amendment No. 1”) filed with the Commission on the date hereof. The Initial Registration Statement, as amended by Amendment No. 1, is referred to herein as the “Registration Statement.”

We have reviewed such corporate records, certificates and other documents, and such questions of law, as we have considered necessary or appropriate for the purposes of this opinion. We have assumed that all signatures are genuine, that all documents submitted to us as originals are authentic and that all copies of documents submitted to us conform to the originals.

We have assumed that, at the time of the issuance, sale and delivery of each series of Debt Securities and each issue of Depositary Shares, Warrants, Subscription Rights or Units, as the case may be: (i) the execution, delivery and performance by the Company of the senior indenture in the form of Exhibit 4.2 to the Registration Statement or the subordinated indenture in the form of Exhibit 4.3 to the Registration Statement, as applicable, and any supplemental indenture thereto (any such indenture, together with any applicable supplemental indenture, the “Indenture”), deposit agreement, warrant agreement, subscription agreement or subscription

rights certificate, and unit agreement (collectively, the “Documents”), as applicable, and all actions necessary for the issuance of the applicable Covered Securities, and the form and terms thereof, will comply with all requirements and restrictions, if any, applicable to the Company, whether imposed by any agreement or instrument to which the Company is a party or by which it is bound or any court or other governmental or regulatory body having jurisdiction over the Company; and (ii) the Company will have duly authorized, executed and delivered any such Document and will have duly authorized the issuance of any such Covered Security, and that none of such authorizations will have been modified or rescinded, and there will not have occurred any change in law affecting the validity, legally binding character or enforceability thereof. We have also assumed that the Covered Securities will be offered and sold in compliance with applicable federal and state securities laws and in the manner stated in the Registration Statement and the appropriate prospectus supplement. We have assumed further that the Documents will be governed by and construed in accordance with the laws of the State of New York. With respect to any Document executed or to be executed by any party other than the Company, we have assumed that such party has, or will have, duly authorized, executed and delivered the Documents to which it is a party and that each such Document is, or will be, the valid and binding obligation of such party, enforceable against it in accordance with its terms.

We have assumed further that the Company is duly organized, validly existing and in good standing under the laws of the State of Washington and has all requisite power, authority and legal right to execute, deliver and perform its obligations under the Covered Securities, the Indenture, and the Documents. With respect to all matters of Washington law, we note that you are relying on an opinion of Keller Rohrback L.L.P., dated as of the date hereof, which opinion is filed as Exhibit 5.2 to Amendment No. 1.

Additionally, we have relied as to certain matters on information obtained from public officials, officers of the Company and other sources believed by us to be responsible.

Based upon the foregoing, and subject to the qualifications set forth herein, we are of the opinion that, when, as and if:

1. With respect to the Debt Securities: (i) Amendment No. 1 and any further required post-effective amendments to the Registration Statement have all become effective under the Securities Act and all prospectus supplements required by applicable law have been delivered and filed as required by such laws; (ii) the Indenture has been duly executed and delivered on behalf of the Company and a trustee qualified to act as such under applicable law (the “Trustee”) and such Indenture has been duly qualified under the Trust Indenture Act of 1939, as amended; (iii) all necessary corporate action has been taken by the Company to authorize, execute and deliver any necessary supplemental indenture and to authorize the form, terms, execution and delivery of the Debt Securities; (iv) any legally required consents, approvals, authorizations and other orders of the Commission and any other regulatory authorities have been obtained; and (v) such Debt Securities have been duly executed by the Company and authenticated by the Trustee in accordance with the Indenture and have been duly
