PATENT ASSIGNMENT AGREEMENT

     This agreement (the “Agreement”) is made effective the 23^rd day of February 2009 (the “Effective Date”) between Omeros Corporation, a Washington corporation having a principal place of business at 1420 Fifth Avenue, Suite 2600, Seattle WA 98101 USA (“Omeros”) and Roberto Ciccocioppo, Ph.D., having a residence at Vicolo San Silvestro n. 25, Camerino, 62032 IT (“Dr. Ciccocioppo”).

     WHEREAS Dr. Ciccocioppo owns all rights to certain technology invented by Dr. Ciccocioppo related to new uses of peroxisome proliferator-activated receptor gamma (“PPARg”) agonists; and

     WHEREAS Omeros has provided services for and funded the expenses of filing patent applications for Dr. Ciccocioppo’ PPARg technology; and

     WHEREAS Omeros wishes to acquire all rights to Dr. Ciccocioppo’ PPARg technology and related patent applications and patents; and

     WHEREAS Dr. Ciccocioppo wishes to sell all rights to his PPARg technology to Omeros in consideration for Omeros undertaking certain future milestone and royalty obligations;

     NOW THEREFORE, in consideration for the mutual covenants and obligations set forth herein as well as other good and valuable consideration, the parties hereby agree as follows:

1		Definitions
1.1		“Intellectual Property Rights” shall mean all inventions, ideas, discoveries, issued, reissued or reexamined patents, pending and future patent applications, continuation, continuation-in-part and divisional patent applications, utility models, inventor’s certificates, trade secrets, know-how, copyrights and trademarks.
1.2		“Assigned Patents” shall mean US Provisional Patent Application No. 60/911,201 filed April 11, 2007, US Patent Application No. 12/101,943 filed April 11, 2008, International Patent Application PCT/US08/60146 filed April 11, 2008, all national and regional counterparts of such International Patent Application, all patent applications claiming priority from the foregoing patent applications, a provisional US Patent Application to be filed based on a disclosure provided to Omeros on November 11, 2008 by Dr. Ciccocioppo entitled “Pioglitazone and Opiates” and corresponding US Utility, International PCT and national phase applications claiming priority therefrom, all other patent applications and patents included as of the Effective Date or during the term of this Agreement in the Assigned IP, all future patents, utility models and inventor’s certificates issuing from all of the above patent applications, and all divisionals, continuations, continuation-in-parts, reissues and reexaminations of all such patent applications and patents.
1.3		“Assigned IP” shall mean Dr. Ciccocioppo’s entire right and title to and interest in all Intellectual Property Rights owned or held by Dr. Ciccocioppo related to PPARg agonists, compositions containing PPARg agonist(s) alone or in combination with other

		therapeutic agents, and therapeutic methods and uses for PPARg agonists and compositions containing PPARg agonist(s) alone or in combination with other therapeutic agents, whether such compositions are administered alone or in conjunction with other therapeutic agents or modalities, as of the Effective Date or invented, developed, advanced or improved by Dr. Ciccocioppo during the term of this Agreement, including, without limitation, methods and compositions for the use of PPARg agonists, singly or in combination and/or in conjunction with other therapeutic agents, for prevention and treatment related to alcoholism and addictive disorders (e.g., addictions to alcohol, nicotine, marijuana, opioid agonists, benzodiazepine, barbiturates, psychostimulants and addictive or compulsive behaviors), and the use of PPARg agonists in combination and/or in conjunction with the administration of narcotic analgesics (e.g., to delay or prevent the development of tolerance and/or addiction to opioid agonists) or for the treatment of other central nervous system conditions, diseases and disorders, and all improvements or inventions related to the foregoing examples, the Assigned Patents and all inventions disclosed and/or claimed in the Assigned Patents, and the future right to file US, ex-US and international patent applications for any other inventions that are included in the Assigned IP or that become included in the Assigned IP during the term of this Agreement, in Dr. Ciccocioppo’s name or in the name of Omeros, as well as all patents issuing from such patent applications.
1.4		“Subject Products” shall mean all therapeutic compositions including one or more PPARg agonists, alone or in combination with other therapeutic agents, that, if offered for sale, sold, manufactured or used by a third party without license from Omeros would infringe any valid, subsisting and enforceable claim(s) of any issued patent or any patentable claim(s) of any pending patent application included within the Assigned Patents in the country or countries in which such compositions are offered for sale, sold, manufactured or used.
1.5		“Net Sales” shall refer, with respect to Subject Products, to (a) the gross total of the monetary compensation invoiced and collected by Omeros for the initial sale or distribution of the Subject Products, but excluding any amounts invoiced or collected by parties other than Omeros for subsequent sales or distribution provided no part of such amounts invoiced or collected by such parties is directly or indirectly paid to Omeros, less (b) the sum of the following actual and customary deductions where applicable: cash, trade, or quantity discounts; sales, use, tariff, import/export duties or other excise taxes, and any other governmental taxes imposed on particular sales; transportation charges and allowances; sales commissions to third parties (but excluding sales commissions to Omeros’ employees); wholesale charge backs; distributor fees; Medicare/Medicaid rebates; customer rebates; refunds for recalls; and allowances or credits to customers because of rejections or returns, provided such deductions are documented. For purposes of this paragraph, the acquisition of Subject Products from Omeros as part of an acquisition or other transfer or conveyance of all or a part of the assets of Omeros’ business to which this Agreement pertains, or as part of a merger, acquisition, reorganization or other change of control of Omeros, shall not be considered a sale or distribution of Omeros Therapeutics.

		If a Subject Product is sold in combination with one or more additional therapeutic agents as a “Combination Product”, Net Sales shall be the product obtained by multiplying Net Sales of the Combination Product by the fraction A/(A+B) where A is the sales price of such Subject Product when sold separately as a composition in which the Subject Product is the only therapeutic agent and B is the total sales price of all additional therapeutic agents in the Combination Product when sold separately in a pharmaceutical therapeutic product including such additional therapeutic agents as the only therapeutic agents. If such Subject Product and the other therapeutic agents are not sold in separate pharmaceutical therapeutic products, the portion of the total cost of the Combination Product attributed to such Subject Product shall be a fraction, the numerator of which shall be the cost of the Subject Product and the denominator of which shall be the total cost of the Combination Product, and the fraction shall be multiplied by the sales price of the Combination Product to arrive at Net Sales.
1.6		“Transfer Fees” shall mean any monetary compensation received by Omeros in connection with the licensing, assignment or other conveyance of rights in the Assigned IP to third parties for the manufacture, sale or distribution of Subject Products; provided, however, that the Transfer Fees shall not include Net Sales or any compensation from such third parties to Omeros to support Omeros’ research and development efforts, to resolve patent infringement disputes concerning the Assigned IP or other Intellectual Property Rights, to purchase equity in Omeros, for licensing under any other Intellectual Property Rights not included in Assigned IP, or for any other purpose other than as direct compensation for the rights conveyed to such third parties in the Assigned IP.
