5.6		Following receipt from the University of the results of all Sponsored Research and the completion of all other necessary and beneficial research activities by Omeros and/or by others to support appropriate government regulatory submissions by Omeros, [†], Omeros shall use reasonable efforts, based on reasonable commercial prudence, to diligently develop and introduce to the market one or more Licensed Products and/or Licensed Research Products. Ongoing performance of research and/or development efforts to generate or further advance one or more Licensed Products and/or Licensed Research Products by Omeros, internally at Omeros and/or under contract with Leicester and/or a third party, shall be deemed to be diligent efforts under this Section 5.6.
5.7		It is Omeros’ current intent to commercially develop and seek regulatory clearance to clinically test and then market an inhibitor of MASP-2 and/or MAp19 activity following

		Leicester’s identification of selective and high-affinity inhibitors of MASP-2 and MAp19 activity and demonstration by Leicester of the therapeutic benefit of such inhibitors in animal models. Within three months of the identification by Omeros of a Licensed Product or Licensed Research Product that is determined by Omeros to be a viable and optimal clinical development candidate, Omeros will submit a development plan to Leicester that sets forth Omeros’ planned activities and estimated timing for the development, regulatory approval and market introduction of one or more Licensed Products and/or Licensed Research products. Assuming anticipated and adequate progress is made in the Sponsored Research [†], Omeros anticipates the identification of an initial potential candidate for a Licensed Product or Licensed Research Product that is a potential clinical development candidate within two years of the commencement of the Sponsored Research. The foregoing statements within this Section 5.7 and such development plan are or will be provided as indications of current or future intentions only, and shall have no binding effect on Omeros, nor shall it give rise to any right or obligation to either party, and any modification, alteration or failure to meet any of these intentions shall have no impact on this Agreement.
6		Payments
6.1		Quarterly royalty and sublicense revenue payments shall be made in British Pounds Sterling by Omeros to Leicester within sixty (60) days of the end of the quarter. Payments shall be computed based on a conversion from any other denomination to British Pounds Sterling for any revenues received or costs and expenses incurred by Omeros during the relevant quarter or other reporting period, as provided herein, using the prevailing exchange rate in effect at the date and time that funds are transferred from Omeros’ account to Leicester’s account (in the case of payment by wire transfer) or at the date and time of issuance of a check by Omeros (in the case of payment by check). Each quarterly payment shall be accompanied by a report specifying (a) the source of the royalties itemized by product and country, (b) any Omeros IP Legal Fees or Third Party License Fees that were deducted from gross proceeds to determine Net License Proceeds or Net Sublicense Proceeds as provided in Sections 1.10 or 1.11 of this Agreement, and (c) the total of all discounts, returns, credits and commissions deducted from gross proceeds to determine Net License Proceeds or Net Sublicense Proceeds as provided in Sections 1.10 or 1.11 of this Agreement. Following the two-year anniversary of the Effective Date of this Agreement, in the event that Omeros receives no such quarterly royalty and sublicense revenue in any given quarter, it shall nevertheless submit a quarterly report to that effect to Leicester within sixty (60) days of the end of the quarter.
6.2		Leicester reserves the right to employ a certified public accountant to review and reconcile the directly relevant accounting records and procedures of Omeros as they relate to the determination of royalties or sublicense revenue fees under Section 5 herein during reasonable business hours and no more than twice a year, and Omeros agrees to make available at Omeros’ place of business all such directly relevant accounting records for that purpose within 30 (thirty) days of written request by Leicester. The cost of such review shall be borne by Leicester, unless it is found that Omeros under-paid a quarterly royalty or sublicense revenue fees for any quarter by an amount of 10% (ten percent) or greater, in which case the cost of such review shall be borne by Omeros.

6.3		In the event any royalty or sublicense revenue fee payments due under Section 5 herein are not timely paid by Omeros, Omeros shall pay to Leicester interest charges on such late payments at a rate of [†] per annum.
6.4		Not withstanding anything to the contrary herein, Omeros shall have no obligation to pay any royalties or sublicense revenue fees under Section 5 for any product based on any patent claim that has been declared invalid or unenforceable by a court or governmental body of competent jurisdiction or based on any patent claim that is not enforceable in the jurisdiction(s) where such products are manufactured, used, sold, offered for sale, imported or distributed.
7		License Progress
7.1		Omeros shall on an annual basis, commencing on the one-year anniversary of the Effective Date of this Agreement and annually thereafter, deliver to Leicester within thirty (30) days after the end of the respective year a written progress report detailing the status of Omeros’ efforts to fund, patent, develop and commercialize Licensed Products and Licensed Research Products.

15.1		Nothing contained in this Agreement confers any right to either party to use in advertising, publicity, or other promotional activities any name, trade name, trademark, or other designation of the other party hereto, and neither party shall make such use without the prior written consent of the other party, provided however Omeros may through written, oral or electronic communication disclose the existence of this Agreement and the names of Leicester, Dr. Schwaeble, Dr. Stover, Dr. Fujita and other of Leicester’s employees and consultants to Omeros’ current and potential employees, directors, consultants, shareholders, investors and corporate partners, and as required to comply with any governmental law, rule or regulation.
16		Miscellaneous
16.1		This Agreement including all appendices and exhibits attached thereto or incorporated by reference therein constitutes the entire understanding of the parties hereto regarding the subject matter of this Agreement, and no other representation, agreement, promise or undertaking altering, modifying, taking from or adding to the terms of this Agreement shall have any effect unless the same is reduced to writing and duly executed by the parties hereto. In the event of any conflict between the main body of this Agreement and any attachments thereto or documents incorporated by reference therein, the provisions of the main body of this Agreement shall control.
16.2		Either party’s failure to enforce any provision of this Agreement will not be considered a waiver of future enforcement of that or any other provision.

16.3		The laws of the state of Delaware, United States, without regard to its conflict-of-laws provisions, shall govern this Agreement, its interpretation and its enforcement, and any disputes arising out of or related to this Agreement.
16.4		The parties agree that, except as provided herein below, any claim or controversy arising out of or relating to this Agreement or breach thereof shall be settled by arbitration in the state of Delaware, United States, in accordance with the commercial rules of the American Arbitration Association by a panel of three arbitrators, one selected by each party and the third selected by the other two arbitrators. In any such arbitration proceeding, judgment upon the award rendered by the arbitrator shall be final and binding upon the parties and may be entered by either party in any court or forum of competent jurisdiction as provided herein below. Notwithstanding the foregoing, both parties agree that any claims or controversies concerning the validity or enforceability of any intellectual property, or the actual or threatened disclosure or misuse of confidential information, may alternately be resolved by a civil action in any court of competent jurisdiction as provided herein below, and both parties further agree that each shall retain the right to seek injunctive relief in any court of competent jurisdiction as provided herein below to prevent a breach, threatened breach or continuing breach of this Agreement which would cause irreparable injury (e.g., breaches of confidentiality or the like).
16.5		Any civil action prosecuted or instituted by either party as permitted herein above with respect to any matters arising out of or related to this Agreement shall be brought in either the United States District Court located in the state of Delaware, United States (if federal subject matter jurisdiction therein lies) or the Superior Court for the state of Delaware, United States (if there is no subject matter jurisdiction in federal court), and each party hereby consents to the jurisdiction and venue of such courts for such purposes.
16.6		In the event that it is necessary for either party of this Agreement to take legal action to enforce any of the terms, conditions or rights contained herein, or to defend any such action, then the prevailing party in such action shall be entitled to recover from the other party all reasonable attorneys fees, costs and expenses related to such legal action.
16.7		In the event that any portion of this Agreement is held invalid or unenforceable by a court of law, that provision will be construed and reformed to permit enforcement of the provision to the maximum extent permissible consistent with the parties’ original intent, and if such construction is not possible, such provision shall be struck from this Agreement, and the remainder of the Agreement shall remain in full force and effect as if such provision had never been part of this Agreement.
16.8		For the purposes of this Agreement, the parties hereto are independent contractors, and nothing in this Agreement shall be construed to place them in the relationship of partners, principal and agent, employer/employee or joint venturers. Except as provided expressly herein, each party agrees that it shall have no authority to bind or obligate the other party, nor shall any party hold itself out as having such authority.

16.9		Neither party will be liable for failure or delay in performing any obligation under this Agreement, or will be considered in breach of this Agreement, if such failure or delay is due to a natural disaster or any cause reasonably beyond such party’s control, provided that such party resumes performance as soon as possible following the end of the event that caused such delay or failure of performance.
16.10		Neither party may assign this Agreement, or any obligation or right under this Agreement, in whole or in part, without the other party’s prior written consent, which consent will not be unreasonably withheld. This Section shall not be construed in any way to limit Omeros’ rights to grant, at Omeros’ sole discretion, sublicenses hereunder. Leicester consents to Omeros’ assignment of this Agreement in whole or in part in connection with the merger, consolidation or transfer of all or substantially all of that portion of Omeros’ assets to which this Agreement relates.
