Thereafter, if requested by Omeros, Hospira and Omeros shall negotiate in good faith and enter into a contract for continued storage of such Product samples, at Omeros’ reasonable cost and expense; provided, however, that at any time following the initial storage period set forth above, if Hospira decides that it will no longer store such samples or Omeros decides it does not wish to continue to have Hospira store such samples, such Party shall provide no less than sixty (60) days’ written notice to the other Party, during which time Omeros will instruct Hospira to either return such samples to Omeros or a third party designated by Omeros, or to destroy such samples. Hospira shall comply with such instructions from Omeros,

provided, however, that Omeros shall reimburse Hospira its reasonable out-of-pocket costs incurred in returning or destroying such samples.

3.8    Marketed Product Stability Samples. Hospira shall, in accordance with SOPs, pull stability samples of Product and either (a) retain, store and test such stability samples in accordance with the Specifications, or (b) ship such stability samples to Omeros or a third party designated by Omeros in accordance with the Specifications. Hospira shall provide Omeros at least sixty (60) days advance written notice prior to disposition of any stability samples after specified storage times have elapsed, and Omeros shall provide instructions on disposal, continued storage or shipment of such samples at Omeros’ reasonable expense. Upon Omeros’ written request, Hospira shall provide stability testing of the Product in accordance with ICH guidance in accordance with a time point matrix to be mutually agreed in writing and Exhibit C of this Agreement. Stability testing is based on an assumed Product shelf life of [†], and should the Product shelf life increase or decrease the stability testing shall be adjusted proportionately.

3.9    Price; Adjustments; Payment.

3.9.1    Product Pricing. Hospira shall invoice Omeros upon Delivery of Product by Hospira, at the Price set forth in Exhibit D of this Agreement.

3.9.2    Price Adjustments. The Price set forth as of the Effective Date of the Agreement [†]. Price increases shall be effective [†] and shall apply to [†], based on the Delivery date proposed by Omeros and accepted by Hospira as set forth in the applicable accepted Purchase Order, and disregarding any subsequent changes to the Delivery date requested by Hospira. [†]. Such increases shall not exceed the lesser of (a) [†], or (b) [†].

Hospira shall use all reasonable efforts to provide written notice to Omeros of any anticipated price increase no later than [†] of any calendar year.

3.9.3    Taxes; VAT; User Fees. Any applicable sales or use tax, excise, customs charges, duties or similar charge, or any other value-added tax (“VAT”) assessment fee or other charge lawfully assessed or charged on the manufacture, sale or transportation of Product delivered and sold pursuant to this Agreement, and all government license filing fees and Prescription Drug User (PDUFA) annual establishment fees, with respect to all Product shall be paid by Omeros. In particular Omeros shall pay to Hospira all VAT due on the Product, if applicable, in accordance with the payment terms set forth in Section 3.9.4, as applicable. Hospira's invoices shall set forth the purchase price and itemize the applicable VAT. Notwithstanding the foregoing, any taxes or payments assessed or charged on Hospira in connection with its activities hereunder (e.g. taxes assessed against income or payments required to be made by Hospira as an employer) shall be borne entirely by Hospira.

3.9.4    Payment Terms. Omeros shall make payment of any undisputed portion of such invoices [†] within [†] after Omeros’ receipt of each such invoice, unless otherwise specifically set forth in this Agreement. If Omeros should default on any undisputed, due and owing payment, interest shall accrue on any undisputed amount that is overdue at the rate of [†] per month.

3.10    Product Forecasts.

3.10.1    Rolling [†] Estimate. For capacity planning purposes, by no later than [†] in advance of Omeros’ desired Product availability date, Omeros shall provide Hospira with a written estimate of Omeros’ [†] quantity of commercial Product that represents the Minimum Percentage of Omeros’ Product Requirements for the first [†] of the Term, such estimate to be used by Hospira solely for [†] planning purposes. Omeros shall not incur any liabilities if such estimate is not met. If Hospira notifies Omeros (and such notification shall be provided to Omeros in writing) that it will be unable to supply Product in accordance with Omeros’ estimate, Omeros shall have the right, in its sole discretion, to [†]. Thereafter, by [†], Omeros shall update such rolling [†] estimate (“Rolling [†] Estimate”) for the period commencing on [†] of the [†]. Upon receipt of each Rolling [†] Estimate, Hospira shall, within [†] days after such receipt, provide Omeros a written (a) acceptance of such estimate (and in such event, Hospira shall plan to allocate its capacity in a manner consistent with such Rolling [†] Estimate), or (b) rejection of such estimate. In the event Hospira rejects any updated Rolling [†] Estimate, Hospira and Omeros shall meet as soon as possible to discuss in good faith the quantities of Product that Hospira would have capacity to provide to Omeros during each of the [†] covered by the Rolling [†] Estimate, and any amount agreed to shall be memorialized by the Parties in writing in a revised Rolling [†] Estimate. In such event and in Omeros’ discretion, Omeros shall have the right to [†].

3.10.2    Notification and Rolling Forecast. Omeros will provide Hospira with written notice when it submits to the FDA, the EMA or other relevant Regulatory Authority in the European Union a supplemental application or similar regulatory application to Omeros’ new drug application (“NDA”) or marketing authorization application (“MAA”), respectively, to enable the marketing of the Product Manufactured by Hospira. Hospira and Omeros will cooperate in scheduling and estimating initial commercial Batches of the Product. On or before the first (1^st) day of each calendar month, beginning at least [†] prior to the anticipated date of commencement of commercial Processing (excluding process validation Batches), Omeros shall provide to Hospira [†] rolling forecast of the quantities of Product that Omeros intends to order from Hospira during such period (“Rolling Forecast”). The [†] of such Rolling Forecast shall constitute a binding order of Omeros and a supply commitment of Hospira for the quantities of Product specified therein (“Firm Commitment”), and the following [†] of the Rolling Forecast shall be a good faith estimate, the [†] of such following [†] period which is binding to the extent set forth in the Supply and Purchase Commitment described in Section 3.11.4.

3.11.1    Purchase Orders. On or before the first (1^st) day of each calendar month, Omeros shall submit a purchase order (each a “Purchase Order”) to Hospira covering Omeros’ purchases of Product pursuant to the [†] of the Firm Commitment that is effective as of such first day, and shall specify the Delivery dates for the Product included in such Purchase Order. Hospira will use commercially reasonable good faith efforts to accept and meet the Delivery date specified by Omeros in the Purchase Order. Omeros shall not, without the written consent of Hospira, designate a Product Delivery date in a Purchase Order that is earlier [†] from the date on which Omeros submits the Purchase Order. For each Purchase Order, Hospira shall provide (a) a confirmation of acceptance of the Purchase Order based on the Product Delivery date specified by Omeros, or (b) a proposed modification of the Purchase Order offering to accept the Purchase Order based on an alternate Product

Delivery date. Upon (x) Omeros’ receipt of Hospira’s confirmation of acceptance of the unchanged Purchase Order, or (y) Hospira’s receipt of Omeros’ written confirmation accepting the modified Purchase Order with the alternate Product Delivery date, such Purchase Order shall become a “Firm Purchase Order.” If Hospira subsequently finds that it is unable to meet the specified Product Delivery date for a Firm Purchase Order, Hospira shall promptly notify Omeros and provide to Omeros an alternative Product Delivery date (which shall not be more than [†] later than the initial Product Delivery date designated in the Firm Purchase Order).

3.11.2    Purchase Order Changes; Cancellation. In the event that Omeros requests any change to the Delivery date set forth in a Firm Purchase Order, Hospira shall attempt to accommodate the Delivery date change within reasonable manufacturing capabilities and efficiencies. [†]. Hospira shall also advise Omeros of the reasonable costs associated with making any such Delivery date change (if any), and Omeros shall be deemed to have accepted the obligation to pay Hospira for such associated, reasonable costs if Omeros indicates in writing to Hospira that Hospira should proceed to make the change. Hospira shall charge Omeros the amount agreed upon in writing by Omeros for making any such Delivery date change. If Omeros cancels a Firm Purchase Order, Hospira shall be relieved of its obligation relating to such order, but Omeros will not be relieved of its obligation of payment unless Hospira agrees to such cancellation in writing; [†]. If Omeros acts in any manner, not including any change requested by Omeros due to changes in regulatory or other Applicable Law or to ensure that the Product meets the Specifications, to directly and effectively interfere with Hospira’s ability to perform in accordance with a given Firm Purchase, Omeros shall remain liable for the full amount of the Firm Purchase Order, regardless of whether such Product is Processed by Hospira or whether Omeros takes Delivery of any such Processed Product; [†]. Notwithstanding the foregoing, Hospira shall use its commercially reasonable efforts to supply Omeros with quantities of Product which are in excess of the quantities specified in a Firm Purchase Order, subject to Hospira’s other supply commitments and manufacturing and equipment capacity.

3.11.3    Agreement Controls. In the event of a conflict between the terms of any Firm Purchase Order and this Agreement, this Agreement shall control.

3.11.4    Supply and Purchase Commitment. Hospira shall supply Omeros with the quantity of Product ordered by Omeros in each Firm Purchase Order, unless the quantity of Product ordered for any calendar quarter exceeds [†], and [†] thereafter, in which event Hospira shall use commercially reasonable efforts to supply quantities in excess of these amounts.

3.11.5    Purchase Commitment. Following completion of the [†] of the Initial Term, Omeros covenants to purchase from Hospira not less than [†] of the [†] of the Rolling Forecast during the [†] of the Initial Term thereafter (the “Minimum Purchase Requirement”). Omeros may shift any portion of its Firm Commitment to the [†] of the [†] of the Rolling Forecast so long as its Minimum Purchase Requirement is met. In lieu of Omeros taking Delivery of each such [†] Minimum Purchase Requirements of Product, Omeros shall have the option, to be exercised in writing if elected by Omeros, to pay for its Minimum Purchase Requirement at the Price set forth in Exhibit D and waive Hospira’s Processing and Delivery obligations for the corresponding amount of Product. In the latter event, Hospira shall invoice Omeros for the amount payable to meet the Minimum Purchase Requirement, and Omeros shall pay Hospira such amount within [†] after receipt of Hospira’s invoice.

3.11.6    Failure/Inability to Supply.

(a)    [†] Percent. If Hospira fails to, or is unable to, supply Omeros with at least [†] percent ([†]%) of the quantity of Product ordered by Omeros pursuant to the greater of (i) all Firm Purchase Orders received during [†], or (ii) Omeros’ Firm Commitment for any [†] period, then Omeros shall have the right, in its sole discretion, to [†].

(b)    [†] Percent. If Hospira fails to, or is unable to, supply Omeros with at least [†] percent ([†]%) of the quantity of Product ordered by Omeros pursuant to the greater of (i) all Firm Purchase Orders received during [†], or (ii) Omeros’ Firm Commitment for any [†], then promptly thereafter Hospira’s and Omeros’ senior executives shall meet to develop a corrective action plan and/or remedy. If such mutually acceptable corrective action plan and/or remedy is not developed and mutually agreed within [†] after the first meeting of such executives, then Omeros shall have the right, in its sole discretion, to either (x) require Hospira to provide in good faith all commercially reasonable technology transfer assistance to Omeros for Omeros to qualify an alternate supplier (other than Hospira), at no cost to Omeros[†], and thereafter such assistance will be provided at Hospira’s standard consulting rates until such transfer is completed; (y) require Hospira to qualify another Hospira site at Hospira’s sole cost; or (z) terminate this Agreement.

3.12    Rework. Hospira will not rework or reprocess Product unless authorized in advance by Omeros in writing and there is a validated process for such rework or reprocessing of Product. Re-inspection does not constitute rework or reprocessing.

3.13    Product Recalls. In the event that any Product is recalled due to (a) the request, directive or order of any Regulatory Authority or other national government authority, (b) the order of a court of competent jurisdiction, or (c) a voluntary recall instituted by Omeros, Omeros shall coordinate such recall, and the Parties shall take all appropriate actions to carry out such recall and shall cooperate with any governmental investigations surrounding such recall. The cost of any such recall shall be borne by Hospira if the recall results from the failure of the Product to meet Specifications or Hospira’s breach of this Agreement, including breach of Hospira’s warranties under Section 4.2, [†] per recall. Further, Hospira shall at Hospira’s expense, replace any recalled Batches (including the purchase of replacement API and other Materials). [†]. The cost of any other recall shall be borne exclusively by Omeros. For purposes of this Agreement, recall expenses shall include the expenses of notification and destruction or return of the recalled Product, cost of the recalled Product, and any costs associated with the APIs and other Materials for and Processing and distribution of replacement Product, but shall not include lost profits of either Party.

3.14    Hazardous Waste. Hospira shall be responsible for destruction of any and all hazardous waste, including rejected or recalled Product, rejected, excess or unsuitable APIs or other Materials, remainder, residue and refuse, subject first to completion of any retention periods and activities specified in this Agreement, in accordance with the Applicable Laws. Omeros shall bear the expense of destruction of hazardous waste, except for any hazardous waste resulting from Hospira’s breach of this Agreement, including breach of any warranty under Section 4.1 herein, for which hazardous waste Hospira shall bear the expense.

3.15    Storage Fee. A storage fee shall be due and payable to Hospira if Omeros stores Product at the Facility for longer than thirty (30) days after Omeros’ Release Authorization; provided, however, that no such storage fee shall accrue or be due or payable should a force majeure event (as described in Article 11) occur, and for the duration of such force majeure event, which directly or indirectly prevents Omeros from moving Product (or having Product moved) from the Facility. The fee shall be [†].

3.16     Shipments per Batch. Hospira shall make up to [†] shipments to Omeros of Product per Batch at no charge to Omeros. Any additional shipments of Product per Batch requested shall be at a fee of [†] per shipment plus shipping costs.

Nothing in this provision is intended to prohibit Hospira from independently developing, manufacturing, and/or selling any pharmaceutical product provided that Hospira does not utilize, refer to, and/or rely upon any Hospira New IP or the Joint New IP in the development, manufacturing, and/or sale of such product in contravention of the exclusive license granted to Omeros herein. The preceding sentence does not in any way convey to Hospira any right or license to Omeros’

Intellectual Property, including the New Omeros IP, or to Omeros’ Confidential Information, or limit Hospira’s obligations with respect to the same as provided in this Agreement.

7.2    License to Hospira. During the Term, Omeros hereby grants to Hospira a royalty-free, non-exclusive license, without a right to sublicense, to use and exploit Intellectual Property owned by or licensed to Omeros and used in connection with the Processing of Product, solely to the extent necessary to Process Product for Omeros under the terms and conditions of this Agreement.

7.3    Product Data. All Product Data, including all Batch Records and other Product-specific Technical Records generated or obtained by Hospira in connection with this Agreement, and all Specifications, including Master Batch Records generated or obtained by Hospira in connection with this Agreement, but excluding General SOPs, shall be the sole and exclusive property of Omeros and shall be deemed to be Omeros’ Confidential Information. Upon expiration or termination of this Agreement or the earlier request of Omeros, Hospira shall send to Omeros at Omeros’ sole and reasonable expense, complete copies of all Product Data and Specifications in written and (where available) editable electronic form. The Product Data shall be prepared, documented and communicated by Hospira in a manner consistent with the Specifications or as otherwise instructed by Omeros.

7.4    No Implied Right or License. Nothing contained in this Agreement shall be implied to grant to either Party any right or license with respect to the other Party’s Intellectual Property or Confidential Information of the other Party, except as specifically provided in this Agreement.

8.1    Confidential Information. Each Party agrees that the disclosing Party has and shall retain sole and exclusive rights of ownership in all Confidential Information disclosed or owned by such Party. Each Recipient agrees that during the term of this Agreement and for five (5) years thereafter it will not use any Confidential Information of the disclosing Party except for the purposes of performing under this Agreement, unless otherwise agreed by the Parties in writing. Each Recipient agrees not to disclose any Confidential Information of the disclosing Party to others (except to Recipient’s employees, consultants, professional advisors, agents and Affiliates who reasonably require disclosure of such Confidential Information to achieve the purposes of this Agreement and who are bound to the Recipient by like obligations as to confidentiality no less stringent than those set forth herein) during the term of this Agreement and for five (5) years thereafter without the prior written consent of the disclosing Party. Hospira agrees that with respect to the Product Data, the Specifications and the Omeros New IP, which are included in Omeros’ Confidential Information, these obligations of non-use and confidentiality, shall subsist beyond five (5) years after the expiration or earlier termination of this Agreement. Each Party agrees to maintain and follow reasonable procedures to prevent unauthorized disclosure or use of the other Party’s Confidential Information and to prevent it from becoming disclosed or being accessed by unauthorized persons. Each Party agrees that it may disclose to authorized persons only such Confidential Information of the disclosing Party as is necessary for each such authorized person to perform its responsibilities under this Agreement. Recipient shall advise the disclosing Party of any disclosure, loss, or use of Confidential Information of the disclosing Party in violation of this Agreement as soon as practicable. Each Party agrees to return or destroy the Confidential Information of the other Party, whether in written, graphic,

electronic or other tangible form, upon written request, provided, however, that legal counsel for each Party may retain an archival copy of Confidential Information solely for purposes of ensuring compliance with this Agreement.

8.2    Disclosure of this Agreement. The terms of this Agreement shall be considered each Party’s Confidential Information, and accordingly except for disclosures expressly permitted under this Agreement, neither Party may release any information to any third party regarding the terms of this Agreement without the prior written consent of the other Party except as required by law or regulation. Notwithstanding the foregoing, the terms of this Agreement may be disclosed by Omeros to its existing or potential investors, acquirers, merger partners, commercial partners, shareholders, directors and professional advisors on a need-to-know basis, each of whom prior to disclosure must be bound by written or professional ethical obligations of confidentiality and non-use at least as restrictive in scope as those set forth in this Article 8 and that are of equivalent or greater duration in view of the circumstances of the disclosure.

8.3    Permitted Disclosures. Notwithstanding anything to the contrary, a Party may disclose the Confidential Information of the other Party only to the extent such disclosure is reasonably necessary (a) to secure patent protection for an Intellectual Property developed pursuant to this Agreement consistent with the ownership set forth in Section 7.1, or (b) to comply with Applicable Law, requirements of any Regulatory Authority or other regulatory or governmental agency, including the FDA, the Securities and Exchange Commission, the Federal Trade Commission and/or the Department of Justice, or judicial order from a court of competent jurisdiction, or (c) in order to conduct pre-clinical or clinical trials or seek Regulatory Approval to market Product. Prior to making any such permitted disclosures, however, the disclosing Party shall give reasonable advance notice to other Party with as much detail as possible in relation to the disclosure. Each Party agrees that it shall cooperate fully and in a timely manner with the other Party with respect to all such permitted disclosures, including determining what information should be released and requests for confidential treatment of Confidential Information of either Party included in any such disclosure; provided, however, that in no event shall a Party be required to delay any filing or release unreasonably hereunder.

8.4    Remedies. Because of the unique nature of the Confidential Information, each Recipient acknowledges and agrees that the disclosing Party may suffer irreparable injury if the Recipient fails to comply with the obligations set forth in this Article 8, and that monetary damages may be inadequate to compensate the disclosing Party for such breach. Accordingly, each Recipient agrees that the disclosing Party will, in addition to any other remedies available to it at law, in equity or otherwise, without the requirement to post a bond, be entitled to seek injunctive relief and/or specific performance to enforce the terms, or prevent or remedy the violation, of this Article 8. This provision shall not constitute a waiver by either Party of any rights to damages or other remedies which it may have pursuant to this Agreement or otherwise.

9.1    No Warranty; Limitation of Liability. EXCEPT AS EXPRESSLY SET FORTH HEREIN, EACH PARTY DISCLAIMS ALL CONDITIONS, REPRESENTATIONS AND WARRANTIES, WHETHER EXPRESS, IMPLIED, STATUTORY OR OTHERWISE,

INCLUDING ANY IMPLIED WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE OTHER THAN THAT THE PRODUCT MEETS THE SPECIFICATIONS, OR ANY WARRANTY OF NON‑INFRINGEMENT OF THIRD PARTY RIGHTS. UNDER NO CIRCUMSTANCES SHALL EITHER PARTY, ANY OF ITS AFFILIATES OR ANY OF THEIR RESPECTIVE DIRECTORS, OFFICERS, EMPLOYEES, REPRESENTATIVES, AGENTS, LICENSORS OR PARTNERS BE LIABLE FOR ANY SPECIAL, INDIRECT, INCIDENTAL, EXEMPLARY, CONSEQUENTIAL OR PUNITIVE DAMAGES OR LIABILITIES (INCLUDING SUCH DAMAGES OR LIABILITIES FOR LOSS OF PROFITS, BUSINESS, USE OR OTHER ECONOMIC ADVANTAGE) ARISING OUT OF OR IN ANY WAY RELATED TO THIS AGREEMENT (INCLUDING PERFORMANCE OR FAILURE TO PERFORM HEREUNDER), EVEN IF SUCH PARTY HAS BEEN ADVISED OF THE POSSIBILITY THEREOF, AND REGARDLESS OF THE LEGAL OR EQUITABLE THEORY (CONTRACT, TORT, OR OTHERWISE).

9.2    Omeros’ Indemnification. Omeros shall indemnify, defend and hold harmless Hospira and its officers, employees and agents (collectively, the “Hospira Indemnitees”) from and against any and all liabilities, obligations, penalties, claims, judgments, demands, suits, costs and expenses (including reasonable attorneys’ fees) (any of the foregoing, “Damages”) arising out of or occurring as a result of a claim or demand made by an unaffiliated third party against a Hospira Indemnitee for property damage or personal injury (including death), in connection with (a) Omeros’ storage, promotion, labeling, marketing, distribution, use or sale of Product, (b) Omeros’ negligence, wrongful act or willful misconduct, (c) any breach by Omeros of its obligations, representations, warranties or covenants under this Agreement, (d) the lack of safety or efficacy of the Product, or (e) any violation of any patent or proprietary right of any third party relating to the Specifications or Product other than Hospira’s General SOPs or other Hospira developed Processing procedures used in the Processing of Product pursuant to this Agreement, except to the extent that any such Damages are caused by (i) any failure of the Product to meet the Specifications or any Latent Defect in the Product caused by a Hospira Indemnitee, (ii) the gross negligence or willful misconduct of a Hospira Indemnitee, (iii) by the breach by a Hospira Indemnitee of its obligations, representations, warranties or covenants under this Agreement, including failure to comply with the Specifications or any Applicable Laws, (iv) by the violation of any patent or proprietary Intellectual Property right of any third party that was known to Hospira and was not known to Omeros at the time of such violation, (v) the purchase, transportation, storage, use, handling or disposal of any hazardous substances in connection with performance of the Services by a Hospira Indemnitee, or (vi) any claim that the Processing or performance of Services by a Hospira Indemnitee pursuant to Hospira’s General SOPs or other Hospira developed Processing procedures violates a proprietary Intellectual Property right of any third party (except to the extent that such claim results from the Specifications or other instructions or directions from Omeros).

9.3    Hospira’s Indemnification. Hospira shall indemnify, defend and hold harmless Omeros and its officers, employees, and agents (collectively, the “Omeros Indemnitees”), from and against any and all Damages arising out of or occurring as a result of a claim or demand made by an unaffiliated third party against an Omeros Indemnitee for property damage or personal injury (including death) in connection with (a) Hospira’s negligence or willful misconduct, (b) any failure of the Product to meet the Specifications, any Latent Defect in the Product caused by Hospira, (c)

any breach by Hospira of its obligations, representations, warranties or covenants under this Agreement, including Hospira’s failure to comply with the Specifications or any breach by Hospira of the Applicable Laws, (d) Hospira’s purchase, transportation, storage, use, handling or disposal of any hazardous substances in connection with performance of the Services, or (e) any claim that the Processing or performance of Services by Hospira pursuant to Hospira’s General SOPs or other Hospira developed development or Processing procedures violates a proprietary Intellectual Property right of any third party (except to the extent that such claim results from the Specifications or other instructions or directions from Omeros), except to the extent that any such Damages are caused by, (i) the gross negligence or willful misconduct of an Omeros Indemnitee, or (ii) by the breach by an Omeros Indemnitee of its obligations, representations, warranties or covenants under this Agreement.

9.4    Procedure. In the event that any third party claim, action or suit is instituted against a Party (the “Indemnified Party”) or its employees, officers or agents in respect of which indemnity may be sought pursuant to this Article 9, the Indemnified Party will promptly notify the other Party (the “Indemnifying Party”) in writing (provided that the failure to give such notice promptly will not prejudice the rights of an Indemnified Party, 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 Indemnified Party gives such written notice, the Indemnifying Party and the Indemnified Party 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 Indemnified Party 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 Indemnified Party 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 Indemnified Party without the Indemnifying Party’s prior written consent. No offer of settlement, settlement or compromise by the Indemnifying Party shall be binding on an Indemnified Party without the Indemnified Party’s prior written consent (which consent shall not be unreasonably withheld, conditioned or delayed), unless such settlement fully releases the Indemnified Party without any liability, loss, cost or obligation to such Indemnified Party, 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 the Indemnified Party’s Intellectual Property without the Indemnified Party’s express prior written consent.

9.5    Insurance. Each Party will procure and maintain, at its own expense, for the duration of the Agreement, and for [†] thereafter if written on a claims made or occurrence reported form, the types of insurance specified below with carriers rated A- VII or better with A.

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 9.5. In the case of cancellation, non-renewal or material change in said coverage, each Party shall promptly provide to the other Party with a new certificate of insurance evidencing that the coverage meets the requirements in this Section 9.5. Each Party agrees that its insurance shall act as primary and noncontributory from any other valid and collectible insurance maintained by the other Party. Each Party may, at its option, satisfy, in whole or in part, its obligation under this Section 9.5 through its self-insurance program, subject to the other Party’s review and approval of the sufficiency of such program.

10.1    Term. This Agreement shall be effective as of the Effective Date, and shall continue for five (5) years after Launch (the “Initial Term”), unless earlier terminated in accordance with this Agreement. This Agreement shall automatically renew for up to two (2) additional twelve (12) -month periods, commencing at the expiration of the Initial Term and any extensions thereof, unless either Omeros or Hospira should terminate the Agreement by giving the other Party written notice of intent to terminate at least twenty-four (24) months prior to the expiration of the Initial Term or any extension thereof. The Initial Term as it may be extended shall be referred to herein as the “Term.”

In the event that a Party materially breaches this Agreement, the other Party shall deliver written notice to the breaching Party describing such breach in detail, which notice shall include a statement of the non-breaching Party’s intent to terminate this Agreement unless such breach is remedied. If the breaching Party does not cure such breach within sixty (60) days following receipt of such written notice from the non-breaching Party, the non-breaching Party may terminate this Agreement by sending a written notice of termination to the breaching Party In the event that a Party goes into liquidation, or seeks the benefit of any

bankruptcy or insolvency act, or a receiver or trustee is appointed for its property or estate, or it makes an assignment for the benefit of creditors, whether any of the aforesaid events be the outcome of the voluntary act of such Party or otherwise, and such procedures are not terminated within ninety (90) days, the other Party may terminate this Agreement by sending a written notice of termination to such Party.

10.3    Termination by Omeros. Omeros shall have the right to terminate this Agreement at any time, without penalty:

10.3.1    for all countries, if, prior to Launch of the Product in any country in the Territory, Hospira and/or the Product fails to meet any performance requirement, standard or Specification or an inability or failure of the Product to be Processed to meet the Specifications;

10.3.2    on a country by country basis within the Territory, if, at any time before or after Launch of the Product in such country(ies) in the Territory (a) applicable Regulatory Authority requirements in one or more countries in the Territory have a material adverse impact on Omeros’ ability to obtain or maintain Regulatory Approval for Product in such country(ies), and/or (b) Omeros receives a materially adverse decision or determination by a Regulatory Authority in such country(ies) in the Territory regarding the Product; and/or

10.3.3    for all countries, if, after Launch of the Product in any country in the Territory Hospira fails to supply at least [†] of the then-current Minimum Percentage for any two consecutive quarters.

Except as specified in this Section 10.3, termination of this Agreement as to any country in the Territory shall not automatically terminate this Agreement for any remaining countries in the Territory.

10.4    Termination Upon Business Development Event. In the event that greater than [†] of Omeros’ stock is acquired by an independent third party, or Omeros enters into a marketing, promotion and/or distribution agreement with an independent third party for the Product (each a “BD Event”), and such third party has the capability and desire to manufacture the Product or to cause the Product to be manufactured by such third party or by Omeros, then Omeros shall have the right to terminate this Agreement with respect to the portion(s) of the Territory, i.e., the United States or the European Union, for which the BD Event pertains with ninety (90) days’ notice to Hospira, wherein such notice shall be delivered to Hospira within ninety (90) days of the execution of the definitive agreement memorializing the BD Event; provided, however, if Omeros terminates this Agreement due to a BD Event pursuant to this Section 10.4, Omeros shall be obligated to purchase, and Hospira shall be obligated to supply, Product for a period of time (“Supply Period”), and shall pay a break-up fee (“Break-Up Fee”), to the extent provided in the following table, in which “Submission” means Omeros’ first regulatory filing for approval to market the Product in which Hospira is referenced as a commercial manufacturer, and “Launch” means the date of completion of the first commercial sale of Product by Omeros or by a third party authorized to sell Product by Omeros, and provided further, that if at the time of a BD Event in the European Union, the Parties have not yet agreed to a minimum manufacture and Supply and purchase and Delivery commitment for the European Union pursuant to Section 2.6.1 of this Agreement, Omeros shall have the right at its discretion to terminate this Agreement with respect to the European Union without either Party being obligated to the applicable

Supply Period, and Omeros not being obligated to pay the applicable Break-Up Fee, from the table below:

The start event in each period (a)-(e) set forth in the table above includes the first day of such event (e.g., (d) covers the period of time between the 1^st year anniversary of Launch and the day prior to the 2^nd year anniversary of Launch).

10.5    Termination by Mutual Consent. The Parties may terminate this Agreement at any time by mutual written consent.

10.6    Effects of Termination.

10.6.1    Return of Omeros Property and Product. Upon expiration or earlier termination of this Agreement for any reason, Hospira shall return to Omeros all Omeros Property and Product (other than samples retained under Section 3.7) within [†] after the date of such expiration or termination.

10.6.2    Technology Transfer. Upon expiration or termination of this Agreement by Omeros pursuant to this Article 10, Hospira shall, during the [†] prior to such expiration or [†] after such termination, provide reasonable operational and technical support, to support the transfer to Omeros (or its designee) all Product Data and such manufacturing technology and know-how in Hospira’s possession, custody, or control that is necessary or beneficial for the Processing of Product (“Technology Transfer”). The purpose of the Technology Transfer is to enable Omeros, or its designee, to manufacture Product in the manner that Hospira Processes Product at the time of such Technology Transfer. The Technology Transfer shall not constitute an assignment of any of Hospira’s Intellectual Property and/or Hospira New IP; provided, however, that this sentence shall not be interpreted to limit the exclusive and nonexclusive licenses to Hospira New IP granted to Omeros for certain purposes under Section 7.1. [†]. The Parties will meet and discuss in good faith beforehand the details of any support to be provided, [†].

10.6.3    Inventory. Upon termination pursuant to this Article 10, and except in instances of breach by Hospira including failure of Product to meet Specifications, Omeros shall purchase all inventory on hand and, if applicable, work in progress and reimburse Hospira for Hospira’s cost of all Materials purchased and on hand or on order, if such supplies were ordered by Hospira based on Firm Purchase Orders or Omeros’ estimates of its requirements of Product, and such supplies cannot be reasonably used by Hospira for other purposes. Hospira shall invoice Omeros for all amounts due hereunder.

11.1    Excuse from Performance. Either Party shall be excused from performing its respective obligations under this Agreement if its performance is delayed or prevented by any event beyond such Party’s reasonable control, including, but not limited to, acts of God, fire, explosion, weather, disease, war, insurrection, civil strife, riots, government action, earthquake, terrorism, or power failure; provided, however, that such performance shall be excused only to the extent of and during such disability and the affected Party shall use commercially reasonable efforts to resume performance as soon as reasonably practicable. Any time specified for completion of performance during or subsequent to the occurrence of any or all such events shall be automatically extended for a commercially reasonable period of time to enable the affected Party to recover from such disability. Hospira shall immediately notify Omeros if, by reason of any of the events referred to herein, Hospira is unable to meet any such time for performance. Capacity constraints due to the volume of business at Hospira shall not be deemed a force majeure event. If Hospira experiences a force majeure event that interferes with Processing of Product at Hospira’s Facility, Hospira shall, at Omeros’ discretion and request, cooperate in good faith with Omeros in expeditiously transferring Processing to another of Hospira’s facilities, if available. The Parties shall mutually discuss and implement in good faith an agreed-upon action plan for such transfer. The Parties understand and agree that Omeros has chosen the excipient and primary container packaging component suppliers listed in the Specifications and Hospira has agreed to such suppliers. Under no circumstances shall Hospira have any liability to Omeros, nor shall Hospira be deemed to be in breach of this Agreement, if Hospira is unable to supply Product to Omeros due to a failure of the primary container supplier to provide such containers to Hospira; provided, however, that Hospira has used all commercially reasonable efforts to obtain the relevant containers from the approved supplier in accordance with Omeros’ forecasts.

12.1    Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware, without regard to conflicts of laws or rules thereof.

The Executives shall attempt to

resolve such dispute through good faith discussions prior to instituting any civil action to resolve such dispute.

12.3    Independent Contractors. For purposes of this Agreement, Hospira shall be deemed to be an independent contractor and not an agent or employee of Omeros or a joint venturer with Omeros, and nothing in this Agreement shall be construed to create any other relationship between Hospira and Omeros. Neither Party shall have any right, power, or authority to assume, create, or incur any expense, liability or obligation, expressed or implied, on behalf of the other Party. Hospira shall be solely responsible for withholding and payment of all appropriate state and federal taxes, including social security payments, with respect to all of its employees.

If deletion of such provision materially alters the basis of this Agreement, then the Parties shall negotiate a good faith alternative.

12.5    Modification/Waiver. This Agreement may not be altered, amended, or modified (nor shall any obligation or breach be deemed waived) in any way, unless such alteration, amendment or modification is in writing and signed by the Parties (or unless such waiver is in writing and signed by the waiving Party).

Neither Party may assign its rights and/or delegate its obligations under this Agreement without the other Party’s prior written consent (which shall not be unreasonably withheld or delayed); provided that either Party may, without such consent, assign or transfer this Agreement (a) to one of its Affiliates, subsidiaries or parent corporation and (b) to any successor in interest (whether by merger, acquisition, asset purchase or otherwise) to all or substantially all of its business to which this Agreement relates, provided that the assigning Party shall provide written notice to the other within thirty (30) days prior to such assignment. Any permitted assignee shall assume all obligations of its assignor under this Agreement. No assignment shall relieve any Party of responsibility for the performance of any accrued obligation which such Party then has hereunder. Any assignment in violation of this Section 12.7 shall be void ab initio.

12.8    Public Announcements. Subject to disclosures permitted under Sections 8.1, 8.2 and 8.3 or as otherwise required by applicable law or regulation, no public announcement relating to this Agreement shall be made by either Party without the prior written consent of the other Party, and neither Party shall use the other Party’s name, trademark or trade name, or the name of any employee of the other Party, in any advertising or news release (including any posting on the worldwide web) without the prior written consent of the other Party.
