10		Indemnification; Limitation of Liability
10.1		Indemnification. Each Party (the “Indemnifying Party”) shall indemnify, defend and hold harmless the other Party, its affiliates, subsidiaries, officers, directors, employees, consultants, and agents (collectively the “Indemnitees”) from any and all liability, loss (including reasonable attorneys’ fees) or damage any of them may suffer as the result of claims, demands, costs or judgments against them by unaffiliated third parties (collectively “Claims”) that arise from the Indemnifying Party’s breach of any of its obligations, representations, covenants and warranties under this Agreement, or the Indemnifying Party’s negligent act or omission, willful misconduct or unlawful act, except and to the extent that such Claims result from the breach by any Indemnitee of any of the Indemnitees’ obligations, representations, covenants and warranties under this Agreement or any of the Indemnitees’ gross negligence, willful misconduct or unlawful act.
		Omeros shall indemnify, defend and hold harmless Affitech, its affiliates, subsidiaries, officers, directors, employees, consultants, and agents from any and all Claims arising directly from infringement by Affitech of third party Intellectual Property Rights due solely to Affitech’s [†], which third party Intellectual Property Rights are specific to such [†] and excluding any Claims that would have arisen if Affitech had [†].
10.2		Procedure. In the event that any third party claim, action or suit is instituted against an Indemnitee in respect of which indemnity may be sought pursuant to Subsection 10.1, the Indemnitee will promptly notify the Indemnifying Party in writing (provided that the failure to give such notice promptly will not prejudice the rights of an Indemnitee, except to the extent that the failure to give such prompt notice materially adversely affects the ability of the Indemnifying Party to defend the claim, action or suit). Promptly after the Indemnitee gives such written notice, the Indemnifying Party and the Indemnitee shall meet to discuss how to respond to such claim, action or suit. The Indemnifying Party shall control the defense of such claim, action or suit. The Indemnitee shall cooperate with the Indemnifying Party in the defense of such claim, action or suit, at the expense of the Indemnifying Party. In any such proceeding, the Indemnitee shall also have the right to retain its own counsel at its own expense. The Indemnifying Party shall not be liable for damages with respect to a claim, action or suit settled or compromised by the Indemnitee without the Indemnifying Party’s prior written consent. No offer of settlement, settlement or compromise by the Indemnifying Party shall be binding on an Indemnitee without the Indemnitee’s prior written consent (which consent shall not be unreasonably withheld, conditioned or delayed), unless such settlement fully releases the Indemnitee without any liability, loss, cost or obligation to such Indemnitee, provided, however, that the Indemnifying Party shall have no authority to take any action as part of any such defense or settlement that invalidates or otherwise compromises or renders unenforceable any of

		the Indemnitees’ Intellectual Property Rights without the Indemnitees’ express prior written consent.
10.3		Limitation of Liability. Without limitation of any Party’s obligations to indemnify third party Claims under Subsection 10.1, neither Party shall be liable for any indirect, consequential, exemplary or incidental damages arising under or in association with this Agreement, except for any such liability arising from fraud by the Party or from any breach of the Party’s obligations regarding Confidential Information or Intellectual Property Rights under this Agreement.
11		Insurance
		Omeros shall procure and maintain during the Agreement Term and for a minimum period of [†] thereafter, product liability insurance in an amount not less than [†] in the annual aggregate and each of Affitech and Omeros shall procure and maintain during the Research Term and for a minimum period of [†] thereafter commercial general Liability including premises operations, blanket contractual liability, personal injury and advertising injury including fire legal liability for bodily injury and property damage in an amount not less than [†] (or monetary equivalent of each above sum based on prevailing currency exchange rates). Each Party shall include the other Party and its subsidiaries, affiliates, directors, officers, employees and agents as additional insureds with respect to the respective insurance coverages set forth above. Each Party shall make available to the other Party, at such other Party’s request, evidence of its maintenance of insurance in satisfaction of its obligations under this Section 11.
12		Use of Names

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.
14.2		No Waiver. 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.

		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 infringement, validity or enforceability of any Intellectual Property Rights, or the actual or threatened disclosure or misuse of any Confidential Information, may alternately be resolved by a civil action in the court of competent jurisdiction specified in Subsection 14.5 herein below, and both Parties further agree that each shall retain the right to seek injunctive relief in the court of competent jurisdiction specified in Subsection 14.5 herein below to prevent a breach, threatened breach or continuing breach of this Agreement that would cause irreparable injury, including, without limitation, breaches of confidentiality, infringement of Intellectual Property Rights or breach of Subsection 7.4 herein above [†].
14.5		Jurisdiction and Venue. 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 California, United States (if federal subject matter jurisdiction therein lies) or the Superior Courts in the state of California, United States (only if there is no subject matter jurisdiction in federal court), and each Party hereby consents to the exclusive jurisdiction and venue of such courts for such purposes.
14.6		Attorney’s Fees.

14.7		Severability. 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.
14.8		Independent Contractors. 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.
