9.4.    Consequences of Expiration or Termination. In the event of expiration or termination of this Agreement in its entirety or with respect to one or more countries in the Territory or with respect to one or more Licensed Products, for any reason:

9.4.1.    All rights and licenses granted by Omeros to JCB hereunder shall immediately terminate with respect to the Terminated Territory or Terminated Product;

9.4.2.    JCB shall and hereby does, effective as of the effective date of expiration or termination, grant Omeros a perpetual, irrevocable, royalty-free, non-exclusive license, with the right to grant multiple tiers of sublicenses, under the JCB Patents and JCB Know-How then owned or Controlled by JCB, to exploit the Licensed Products in the Terminated Territory, or to exploit the Terminated Product in the Territory, as the case may be.

9.5.    Remedies. Except as otherwise expressly provided herein, termination of this Agreement (either in its entirety or with respect to one or more country(ies)) in accordance with the provisions hereof shall not limit remedies that may otherwise be available in law or equity.

9.6.    Accrued Rights; Surviving Obligations. Expiration or termination of this Agreement (either in its entirety or with respect to one or more countries in the Territory or with respect to one or more Licensed Products) for any reason shall be without prejudice to any rights that shall have accrued to the benefit of a Party prior to such termination or expiration. Such termination or expiration shall not relieve a Party from obligations that are expressly indicated to survive the termination or expiration of this Agreement. Without limiting the foregoing, Sections 3.2.1, 3.3.5, 3.6, 4.1 – 4.5 (as to any payment obligations that accrue during the Term), 4.6, 4.7, 4.8, 5.1, 9.4 and this Section 9.6 and Articles 6, 8 and 10 of this Agreement shall survive the termination or expiration of this Agreement for any reason. If this Agreement is terminated with respect to Terminated Territory or Terminated Products but not in its entirety, then following such termination the foregoing provisions of this Agreement shall remain in effect with respect to the Terminated Territory or Terminated Products to the extent they would survive and apply in the event the Agreement expires or is terminated in its entirety or as otherwise necessary for any of Omeros and its Affiliates and its and their (sub)licensees to exercise their rights in the Terminated Territory or with respect to the Terminated Products, and all provisions not surviving in accordance with the foregoing shall terminate with respect to the Terminated Territory or Terminated Products and be of no further force and effect (and for the avoidance of doubt all provisions of this Agreement shall remain in effect with respect to all countries in the Territory other than the Terminated Territory and all Licensed Products other than the Terminated Products).

ARTICLE 10 MISCELLANEOUS

10.1.    Force Majeure. Neither Party shall be held liable or responsible to the other Party or be deemed to have defaulted under or breached this Agreement for failure or delay in fulfilling or performing any term of this Agreement (other than an obligation to make payments) when such failure or delay is caused by or results from events beyond the reasonable control of the non-performing Party, including fires, floods, earthquakes, hurricanes, embargoes, shortages, epidemics, quarantines, war, acts of war (whether war be declared or not), terrorist acts, insurrections, acts of God (except to the extent any such delay results from the breach by the non-performing Party or any of its Affiliates of any term or condition of this Agreement). The non-performing Party shall notify the other Party of such force majeure within thirty (30) days after such occurrence by giving written notice to the other Party stating the nature of the event, its anticipated duration and any action being taken to avoid or minimize its effect. The suspension of performance shall be of no greater scope and no longer duration than is necessary and the non-performing Party shall use commercially reasonable efforts to remedy its inability to perform. Without limitation to the foregoing, in the event that JCB is the non-performing Party and the suspension of performance continues for one hundred eighty (180) days after the date of the occurrence, Omeros shall have the right to terminate this Agreement upon written notice to JCB, in its sole discretion, solely with respect to the country in the Territory or the Licensed Product affected by such non-performance or in its entirety.

10.2.    Assignment. JCB may not assign its rights or, except as expressly permitted hereunder, delegate its obligations under this Agreement, whether by operation of law or otherwise, in whole or in part, without the prior written consent of Omeros; provided that such consent shall not be required (provided that JCB notifies Omeros of any such assignment within [†]) for any assignment of this Agreement by JCB in connection with (i) a change in the Persons that beneficially own, directly or indirectly, the shares of capital stock of JCB then outstanding and normally entitled to vote in the election of the directors of JCB representing fifty percent (50%) or more of the total voting power of all outstanding classes of such capital stock of JCB, unless the Persons that gain such controlling interest of JCB are engaged in a business that competes, directly or indirectly, with any business of Omeros, or (ii) a sale or transfer to a Third Party, in one or more related transactions, of the assets representing all or substantially all of JCB’s assets to which this Agreement relates, unless such Third Party is engaged in a business that competes, directly or indirectly, with any business of Omeros. Omeros shall have the right to assign this Agreement or delegate any of its rights or obligations under this Agreement to any Affiliate or Third Party and shall notify JCB of any such assignment to a Third Party within [†] of such assignment. Any permitted successor of a Party or any permitted assignee of all of a Party’s rights under this Agreement that has also assumed all of such Party’s obligations hereunder in writing shall, upon any such succession or assignment and assumption, be deemed to be a party to this Agreement as though named herein in substitution for the assigning Party, whereupon the assigning Party shall cease to be a party to this Agreement and shall cease to have any rights or obligations under this Agreement. All validly assigned rights of a Party shall inure to the benefit of and be enforceable by, and all validly delegated obligations of such Party shall be binding on and be enforceable against, the permitted successors and assigns of such Party. Any attempted assignment or delegation in violation of this Section 10.2 shall be void and of no effect.

10.3.    Severability. If any provision of this Agreement is held to be illegal, invalid or unenforceable under any present or future law and if the rights or obligations of either Party under this Agreement will not be materially and adversely affected thereby, (i) such provision shall be fully severable, (ii) this Agreement shall be construed and enforced as if such illegal, invalid or unenforceable

† DESIGNATES PORTIONS OF THIS DOCUMENT THAT HAVE BEEN OMITTED PURSUANT TO A REQUEST FOR CONFIDENTIAL TREATMENT FILED SEPARATELY WITH THE COMMISSION

21

provision had never comprised a part hereof, (iii) the remaining provisions of this Agreement shall remain in full force and effect and shall not be affected by the illegal, invalid or unenforceable provision or by its severance herefrom and (iv) in lieu of such illegal, invalid or unenforceable provision, there shall be added as a part of this Agreement a legal, valid and enforceable provision as similar in terms to such illegal, invalid or unenforceable provision as may be possible and reasonably acceptable to the Parties. To the fullest extent permitted by Applicable Law, each Party hereby waives any provision of law that would render a provision illegal, invalid or unenforceable.

10.4.    Dispute Resolution. Except as provided in Sections 4.8 and 10.8, if a dispute arises between the Parties in connection with or relating to this Agreement or any document or instrument delivered in connection herewith (a “Dispute”), then either Party shall have the right to refer such Dispute to the Executive Officers for attempted resolution by good faith negotiations during a period of [†]. Any final decision mutually agreed to by the Executive Officers shall be conclusive and binding on the Parties. If such Executive Officers are unable to resolve any such Dispute within such [†] period, then each Party shall, except as provided in Sections 4.8 and 10.8, be entitled to seek relief for such Dispute through binding arbitration in Seattle, Washington in accordance with the then-current Commercial Rules of the American Arbitration Association.

10.5.    Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Washington, excluding any conflicts or choice of law rule or principle that might otherwise refer construction or interpretation of this Agreement to the substantive law of another jurisdiction. The Parties agree to exclude the application to this Agreement of the United Nations Convention on Contracts for the International Sale of Goods.

10.6.    Notices. Any notice, request, demand, waiver, consent, approval or other communication permitted or required under this Agreement shall be in writing, shall refer specifically to this Agreement and shall be deemed given only if delivered by hand or sent by facsimile transmission (with transmission confirmed) or by overnight delivery service that maintains records of delivery, addressed to the Parties at their respective addresses specified below or to such other address as the Party to whom notice is to be given may have provided to the other Party in accordance with this Section 10.6. Such Notice shall be deemed to have been given as of the date delivered by hand or transmitted by facsimile (with transmission confirmed) or on the second Business Day (at the place of delivery) after deposit with an overnight delivery service. Any notice delivered by facsimile shall be confirmed by a hard copy delivered as soon as practicable thereafter. This Section 10.6 is not intended to govern the day-to-day business communications necessary between the Parties in performing their obligations under the terms of this Agreement. The parties agree that any notice delivered to Omeros by one of JCB Laboratories, LLC or Fagron Compounding Services, LLC shall be deemed adequate notice by JCB, and any notice from Omeros delivered to one of JCB Laboratories, LLC or Fagron Compounding Services, LLC shall be adequate for notice to JCB.

10.7.    Entire Agreement; Amendments. This Agreement, together with the Schedules attached hereto, sets forth and constitutes the entire agreement and understanding between the Parties with respect to the subject matter hereof and all prior agreements, understandings, promises and representations, whether written or oral, with respect thereto, are superseded hereby. No amendment, modification, release or discharge shall be binding upon the Parties unless in writing and duly executed by authorized representatives of both Parties. In the event of any inconsistencies between this Agreement and any schedules or other attachments hereto, the terms of this Agreement shall control. This Agreement expressly supersedes the Mutual Confidential Disclosure Agreement between the Parties dated as of September 19, 2014, and all Confidential Information exchanged between the Parties under such Mutual Confidential Disclosure Agreement shall be deemed to have been disclosed under and shall be governed by the terms of this Agreement.

10.8.    Equitable Relief. Each Party acknowledges and agrees that the restrictions set forth in Article 6 are reasonable and necessary to protect the legitimate interests of the other Party and that such other Party would not have entered into this Agreement in the absence of such restrictions and that any breach or threatened breach of any provision of such Article may result in irreparable injury to such other Party for which there will be no adequate remedy at law. In the event of a breach or threatened breach of any provision of such Article, the non-breaching Party shall be authorized and entitled to seek from any court of competent jurisdiction injunctive relief, whether preliminary or permanent, which rights shall be cumulative and in addition to any other rights or remedies to which such non-breaching Party may be entitled in law or equity. Both Parties agree to waive any requirement that the other (i) post a bond or other security as a condition for obtaining any such relief and (ii) show irreparable harm, balancing of xxxxx, consideration of the public interest or inadequacy of monetary damages as a remedy. Nothing in this Section 10.8 is intended or should be construed, to limit either Party’s right to equitable relief or any other remedy for a breach of any other provision of this Agreement.

10.9.    Waiver and Non-Exclusion of Remedies. Any term or condition of this Agreement may be waived at any time by the Party that is entitled to the benefit thereof, but no such

† DESIGNATES PORTIONS OF THIS DOCUMENT THAT HAVE BEEN OMITTED PURSUANT TO A REQUEST FOR CONFIDENTIAL TREATMENT FILED SEPARATELY WITH THE COMMISSION

23

waiver shall be effective unless set forth in a written instrument duly executed by or on behalf of the Party waiving such term or condition. The waiver by either Party hereto of any right hereunder or of the failure to perform or of a breach by the other Party shall not be deemed a waiver of any other right hereunder or of any other breach or failure by such other Party whether of a similar nature or otherwise. The rights and remedies provided herein are cumulative and do not exclude any other right or remedy provided by Applicable Law or otherwise available except as expressly set forth herein.

10.10.    No Benefit to Third Parties. Except as provided in Article 8, covenants and agreements set forth in this Agreement are for the sole benefit of the Parties hereto and their successors and permitted assigns and they shall not be construed as conferring any rights on any other Persons.

10.11.    Further Assurance. Each Party shall duly execute and deliver or cause to be duly executed and delivered, such further instruments and do and cause to be done such further acts and things, including the filing of such assignments, agreements, documents and instruments, as may be necessary or as the other Party may reasonably request in connection with this Agreement or to carry out more effectively the provisions and purposes hereof or to better assure and confirm unto such other Party its rights and remedies under this Agreement.

10.12.    Relationship of the Parties. It is expressly agreed that Omeros, on the one hand and JCB, on the other hand, shall be independent contractors and that the relationship between the two Parties shall not constitute a partnership, joint venture or agency. Neither Omeros, on the one hand, nor JCB, on the other hand, shall have the authority to make any statements, representations or commitments of any kind or to take any action, that will be binding on the other, without the prior written consent of the other Party to do so.

10.13.    References. Unless otherwise specified, (i) references in this Agreement to any Article, Section or Schedule shall mean references to such Article, Section or Schedule of this Agreement, and (ii) references to any agreement, instrument or other document in this Agreement refer to such agreement, instrument or other document as originally executed or, if subsequently amended, as so amended and in effect at the relevant time of reference thereto.

10.14.    Construction. Except where the context otherwise requires, wherever used, the singular shall include the plural, the plural the singular, the use of any gender shall be applicable to all genders and the word “or” is used in the inclusive sense (and/or). Whenever this Agreement refers to a number of days, unless otherwise specified, such number refers to calendar days. The captions of this Agreement are for convenience of reference only and in no way define, describe, extend or limit the scope or intent of this Agreement or the intent of any provision. The term “including,” “include,” or “includes” as used herein shall mean including, without limiting the generality of any description preceding such term. The language of this Agreement shall be deemed to be the language mutually chosen by the Parties and no rule of strict construction shall be applied against either Party hereto.

10.15.    Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. This Agreement may be executed by facsimile, PDF format via email or other electronically transmitted signatures and such signatures shall bind each Party hereto as if they were original signatures.
