The Parties agree to notify each other promptly of any known problems with respect to the Process Requirements relating to Product and to work to resolve such problems in good faith and in a prompt and efficient manner so as to permit continued production and shipment of conforming Product, in accordance with all applicable regulatory requirements. Costs for correction of any such Process Requirements shall be allocated between the Parties in a fair and equitable manner and in accordance with the respective obligations of the Parties hereunder and under any related agreements.

Manufacturing Improvements.

Responsibilities. DSM shall use commercially reasonable efforts to identify and implement ways to reduce costs with respect to Manufacturing (“Manufacturing Improvements”), provided that Omeros has first had an opportunity to review and has provided advanced written consent to such Manufacturing Improvements, including capital expenditure, prior to implementation and such Manufacturing Improvements are made under appropriate change controls, including but not limited to improvements in quality and technology and the use of best practices relating to the Manufacture of Product and Applicable Pharmaceutical Law, reduction of waste associated with the Manufacture of Product, packaging and process time reduction in respect of the Manufacture of Product, and improvements in the supply chain efficiency between DSM and OMEROS in connection with the performance of this Agreement (including order/delivery process and delivery procedures).

Allocation of Benefits. Unless otherwise mutually agreed upon by the Parties, net benefits and any cost savings resulting from any improved efficiencies achieved as the result of Manufacturing Improvements shall be (i) allocated to DSM if such Manufacturing

Long Term Forecast. Within [†] days after the Effective Date, OMEROS shall deliver to DSM a non-binding forecast of OMEROS’ quantity requirements for each Commercial Product for the remainder of the Term, on a Contract Year-by-Contract Year basis (the “Long Term Forecast”). The Long Term Forecast shall thereafter be updated every [†] during the Term of this Agreement. If DSM is unable to accommodate any portion of the Long Term Forecast (other than the Firm Purchase Commitment), it shall notify OMEROS and the Parties shall agree on any revisions to the forecast and the Requirements Obligation.

Monthly Forecast. Beginning at least [†] days prior to the first month during which OMEROS requires Commercial Product from DSM hereunder, OMEROS shall submit to DSM a written non-binding estimate of its monthly requirements for such Product for each of the succeeding months in the Term (the “Monthly Forecast”). The Monthly Forecast shall be updated monthly on the [†] day of the month on a rolling basis. If OMEROS fails to update the Monthly Forecast, then DSM shall apply OMEROS’ most recently forecasted requirements in planning the production schedule; and OMEROS shall be obligated to purchase such quantities to the extent that they become part of the Firm Purchase Commitment. If DSM lacks the capacity to Manufacture (i) quantities stated for any new month in the Monthly Forecast, or (ii) quantities in excess of previously forecasted quantities (collectively, the quantities in (i) and (ii) referred to as “Additional Quantities”), then DSM shall notify OMEROS in writing within five (5) calendar days after receipt of the Monthly Forecast; otherwise such Additional Quantities shall be deemed to have been approved and accepted by DSM. The Parties shall negotiate in good faith to resolve any issues in respect of the Additional Quantities that DSM is unable to accept for any month(s) stated in the Monthly Forecast, according to DSM’s available capacity. Notwithstanding the two preceding sentences, OMEROS shall in any event be entitled to increase the aggregate quantity of Product specified during any given [†] period of the Monthly Forecast by [†] Batches of Commercial Product, except that DSM shall not be required to Manufacture such Additional Quantities that, at the time requested by OMEROS, are requested to be Manufactured within the current Firm Purchase Period if DSM does not at the time of such request have the capacity to Manufacture such excess quantities during the current Firm Purchase Period.

Firm Purchase Commitment. Commencing upon OMEROS’ receipt of the first Product Approval for a Product and thereafter, the forecast for the current month plus the next [†] months following the current month of the Monthly Forecast (the “Firm Purchase Period”) shall constitute a firm purchase and supply commitment (the “Firm Purchase Commitment”), which shall state in detail the quantities of Products ordered and the required delivery dates, and shall be binding on the Parties regarding Products to be purchased and supplied. The forecast for the remaining months of the Monthly Forecast

Materials/Lead Times. DSM shall order Excipients and other materials necessary for the manufacture of Products in accordance with the lead-times set forth in ANNEX 1 hereto. In addition, if due to unanticipated circumstances, any raw materials require a longer lead-time, DSM shall be entitled to order such materials as it reasonably deems appropriate to fulfill its obligations hereunder in a timely manner, provided that DSM shall consult with OMEROS before placing any such order.

Zero Quantities. If, at any time following the First Commercial Sale of a Product, OMEROS forecasts zero (0) quantities for [†] during the Term (the “Zero Forecast Period”) for any reason, then DSM shall have the option, at its sole discretion, to provide a [†] notice to OMEROS of DSM’s intention to terminate this Agreement with respect to such Product as of a specified date within the Zero Forecast Period; and OMEROS shall thereafter have [†] to (a) withdraw the zero forecasts and re-submit a non-zero quantity forecast, or (b) negotiate other terms and conditions on which this Agreement shall remain in force and effect with respect to such Product; otherwise, DSM shall have the right to terminate this Agreement at the end of the [†] notice period in accordance with Section 11.6.

Business Interruption/Allocation. If for any reason DSM experiences a business interruption or plant outage that prevents DSM from supplying full contract quantities of any Product to OMEROS for any period of time, then DSM shall give due notice of such conditions to OMEROS and OMEROS shall be accorded equal treatment as among all DSM customers and then-current production commitments on a pro rata basis, subject to the following priorities, provided that in all cases DSM shall use best efforts to ensure that OMEROS’ Product does not stock out:

First (1^st) priority: [†];

Second (2^nd) priority: [†]; and

Third (3^rd) priority: [†].

Obsolete Stock. OMEROS shall reimburse DSM for the Acquisition Cost of all materials that DSM has purchased pursuant to Section 6.4 for the manufacture of Products, where such materials were reasonably acquired, including without limitation with respect to cost, quantity and shelf life, and have expired or are rendered obsolete due to changes in artwork, specifications, or regulatory changes and can no longer be used in the manufacture of Products (“Obsolete Stock”). In addition to reimbursement of DSM’s

Failure/Inability to Supply.

Late Delivery. If DSM fails to supply to OMEROS the quantities of Commercial Product specified in a Purchase Order by the Delivery Date specified therein, and such quantities are consistent with the then current Monthly Forecast, or are consistent with Additional Quantities accepted (or deemed accepted) pursuant to Section 6.2, then DSM shall apply a discount of [†] of the Product Price to the applicable invoice for the delayed shipment for each shipment which is delayed more than [†] beyond the Delivery Date or [†] of the Product Price to the applicable invoice for the delayed shipment for each shipment which is delayed more than [†] beyond the Delivery Date. DSM shall not delay any scheduled Manufacturing of a Batch for OMEROS for any reason based on the comparative economics of Manufacturing for a Third Party.

Failure to Supply at Least [†]. If DSM fails to, or is unable to, supply OMEROS with at least [†] of the aggregate quantity of Product set forth in all Purchase Orders submitted by OMEROS during [†] in which Purchase Orders are consistent with the then current Monthly Forecast and have been accepted by DSM, then any obligation of OMEROS under this Agreement to purchase quantities of such Product following the then-current Firm Commitment Period (pursuant to the Requirements Obligation or otherwise) shall be decreased by the percentage by which DSM’s delivery of Product in such [†] period fell short of the quantity of Product ordered by OMEROS. Such decrease shall only apply to the Firm Purchase Commitment Period immediately following the period during which DSM failed to supply [†] of the Product.

Failure to Supply at Least [†]. If DSM fails to, or is unable to, supply OMEROS with at least [†] of the aggregate quantity of Product set forth in all Purchase Orders submitted by OMEROS during [†] in which Purchase Orders are consistent with the then current Monthly Forecast and have been accepted by DSM, then DSM’s and OMEROS’ senior executives shall promptly meet to develop a plan of corrective action for DSM and DSM shall use reasonable best efforts to supply OMEROS with additional Commercial Product up to the quantity previously requested in Purchase Orders unless requested otherwise by OMEROS or mutually agreed otherwise by the Parties. If a corrective action plan is not mutually agreed upon within twenty (20) days after the first meeting of such executives and then timely complied with, then OMEROS shall have the right, in its sole discretion, to terminate this Agreement.

Rework. DSM will not rework or reprocess Product unless authorized in advance by OMEROS in writing and then only at DSM’s cost, unless otherwise authorized by OMEROS due to the rework being necessitated by the fault of OMEROS, and using a validated process for such rework or reprocessing of Product. Re-inspection does not constitute rework or reprocessing.

Purchase Orders.

Submission of Purchase Orders. Except to the extent the Parties may otherwise agree with respect to a particular shipment, all Commercial Products shall be ordered by OMEROS by submission to DSM of written purchase orders (each, a “Purchase Order”), stating the Commercial Product, Unit quantities, and Delivery Dates, which shall be sent to DSM not less than [†] prior to the Delivery Dates specified in such Purchase Orders. DSM shall accept or reject each Purchase Order in writing within [†] of receipt, and shall be deemed to have accepted a Purchase Order if not rejected within such [†] period. The quantity specified in a Purchase Order for a month shall be consistent with the then-current Monthly Forecast for such month, after taking into account OMEROS’ ability to increase the aggregate quantity of Product specified in the Monthly Forecast as provided for in Section 6.2. Should OMEROS submit a Purchase Order to purchase Product in a given month in an amount greater than the quantity forecast for such month in the most recent Monthly Forecast provided by OMEROS to DSM pursuant to Section 6.2, then DSM shall use commercially reasonable efforts to supply such excess quantity but shall not be liable to OMEROS for any inability to do so. Upon receipt of each Purchase Order by DSM, DSM shall supply the Product(s) in such quantities and shall use its best efforts to deliver such Product(s) to OMEROS no later than [†] after the Delivery Dates specified in the Purchase Order. Development Product shall be ordered in accordance with the terms set forth in the applicable statement of work attached to Annex 5.

Changes in Purchase Orders. Once received by DSM, Purchase Orders may not be modified without DSM’s prior written consent, which shall not be unreasonably withheld. Should OMEROS desire to increase the amount of Product to be supplied by DSM pursuant to any Purchase Order already submitted, OMEROS shall so notify DSM and DSM shall use commercially reasonable efforts to supply such excess quantity but shall not be liable to OMEROS for any inability to do so. OMEROS shall be charged a Cancelled Production Fee for any Purchase Orders cancelled by OMEROS (unless such cancellation occurs in conjunction with the termination of this Agreement by OMEROS pursuant to Section 11.3, 11.4, 11.5 or 17.1). Upon OMEROS’ payment of the Cancelled Production Fee, the cancelled quantities shall be credited against the Requirements Obligation and be deducted from the Firm Purchase Commitment in proportion to the percentage of the Product Price for the cancelled quantity of Product paid.

Minimum Purchase Requirements Not Affected. If OMEROS requests any change to decrease the ordered quantity, any delays, or cancellation of any Purchase Order, and if DSM accepts such change, delay, or cancellation, DSM’s acceptance shall not reduce or eliminate OMEROS’ Firm Purchase Commitment and any other applicable minimum purchase requirements. Subject to Section 6.8.2, satisfaction of the Firm Purchase Commitment and other minimum purchase requirements shall be determined on the basis of actual quantities purchased (or Cancelled Production Fees paid) for the relevant period.

Additional Terms. Any additional or conflicting terms and conditions that may be printed on Purchase Orders issued by OMEROS or any acceptances issued by DSM shall have no force or effect between the Parties unless mutually agreed by the Parties in writing.

Purchase Quantities. All Commercial Product shall be ordered in Batch sizes, as set forth in Annex 1 hereto or whole multiples thereof. Each Purchase Order shall specify the quantity of Units of Commercial Product being ordered. Quantities actually shipped pursuant to a given Purchase Order may vary from the quantities reflected in such Purchase Order by up to [†] above or below the stated quantities and still be deemed to be in compliance with such Purchase Order; provided, however, that OMEROS shall only be invoiced for actual delivered quantities.

Delivery Terms. The terms of delivery for the Product shall be F.O.B. DSM’s [†] plant. Title and risk of loss and/or damage to the Product shall pass to OMEROS upon delivery of the Product to the carrier at DSM’s [†] plant. All Products shall be (a) properly prepared for safe and lawful shipment (in compliance with Applicable Law) by DSM, (b) shipped to OMEROS’ distribution center or other location designated by OMEROS, in accordance with OMEROS’s approved packaging and shipping configurations, via the common carrier designated by OMEROS and (c) accompanied by appropriate transportation and other agreed upon documentation. No products of any Third Party shall be shipped with the Products. Shipping costs prepaid by DSM will be billed to OMEROS monthly by DSM on separate invoices. Each delivery of Product shall be accompanied by a Product Certificate of Analysis and other such documents as may be required by the Quality Agreement or Applicable Law.

Invoicing. DSM shall invoice OMEROS upon shipment of Commercial Product in accordance with Section 8.4. Validation Batches and pre-launch Commercial Product shall be invoiced in accordance with Section 2.3, irrespective of whether or not Product Approval has been granted by the FDA.

Import and Export Matters. As between the Parties, OMEROS shall prepare, obtain, and maintain all necessary import and export registrations relating to the Product and the API. DSM shall be responsible for Manufacturing all Product hereunder in accordance with Applicable Pharmaceutical Law.

Price. For Commercial Product, OMEROS shall pay DSM the Product Price set forth in ANNEX 1 hereto, subject to adjustment as set forth in Section 8.2.

Price Adjustments.

API Supply. If OMEROS elects to require DSM to procure API, then the total Product Price payable for a Commercial Batch shall be adjusted by the Acquisition Cost of the API required to Manufacture such Commercial Batch plus [†].

Unapproved Vendor Price Changes. Any price increase in Excipients as implemented by Unapproved Vendors shall be passed through directly to OMEROS by a corresponding

Costs of Specifications Changes. The Product Price may also be increased or decreased by mutual agreement of the Parties in connection with Specification changes made by OMEROS pursuant to Section 5.6. In the event that the Parties do not agree on the new Product Price that reasonably relates to the Specification changes to apply to Product embodying such Specification changes, DSM shall have the right in its sole discretion to terminate this Agreement.

Cost Reductions from Manufacturing Improvement Program. The Product Price shall be adjusted to reflect cost savings resulting from Manufacturing Improvements to the extent that the net benefits and cost savings resulting from such Manufacturing Improvements are allocated to OMEROS in accordance with Section 5.9.

Compliance with Foreign Regulatory Authorities. The Product Price may be increased by DSM, subject to OMEROS’ approval, which shall not be unreasonably withheld, to reimburse DSM for any additional necessary services reasonably performed and costs reasonably incurred by DSM as necessary to comply with changes in regulatory requirements outside of the Territory.

Taxes. The Product Prices set forth in each Product Addendum included in ANNEX 1 do not include sales, use, consumption, or excise taxes of any taxing authority. The amount of such taxes, if any, will be added to the Product Prices in effect at the time of shipment thereof and shall be reflected in the invoices submitted to OMEROS by DSM pursuant to this Agreement. OMEROS shall pay the amount of such taxes to DSM in accordance with the payment provisions of this Agreement.

Invoicing; Method of Payment. At the time of each shipment of Product hereunder, DSM shall invoice OMEROS, and OMEROS shall pay such invoices within thirty (30) days of the invoice date. Payments received after the due date may be subject to interest at a rate equal to the lesser of (a) [†] per month and (b) the maximum amount permitted by Applicable Law. All payments due hereunder to DSM shall be sent to DSM at the times set forth herein by check or wire transfer to such accounts as DSM may designate to OMEROS in writing from time to time in accordance with Section 21.11.

Audits. OMEROS shall have the option, on an annual calendar-year basis and more frequently for cause, to request an audit of any Product prices or other charges invoiced by DSM during the preceding Contract Year. Such audits shall be performed by an independent certified public accountant, mutually agreeable to OMEROS and DSM (the “Independent Auditor”), who shall be permitted to review DSM’s records and accounts relating to this Agreement to verify that invoices issued hereunder were correctly prepared. The Independent Auditor shall only report to OMEROS whether the invoices were correctly calculated; and if not, the amount by which the invoices were over-stated or under-stated. OMEROS shall not otherwise have access to the financial records of DSM. The Independent Auditor shall be subject to the confidentiality provisions set forth

DSM shall maintain inventory control and reporting systems adequate to provide OMEROS upon request monthly, quarterly and annual reports of API and Excipient Supply inventory, work in progress inventory and Product inventory.

Product recalls and FDA contacts relating to recall of Product shall be the responsibility of, and under the control of, OMEROS. However, in the event that either Party has reason to believe that any Products should be recalled or withdrawn from distribution, such Party shall promptly inform the other in writing prior to taking any such action. OMEROS shall notify the FDA and other Governmental Authorities, as appropriate, of any recall, and shall be responsible for coordinating all necessary activities regarding the action taken. DSM and OMEROS acknowledge that each Party has significant regulatory obligations; and accordingly, each Party shall fully cooperate with the other to complete the recall, and shall thereafter resolve any allocation of liability as may be appropriate in accordance with the terms of this Agreement.

OMEROS shall give DSM prompt written notice of any Product recalls that OMEROS believes were caused or may have been caused by DSM’s failure to comply with this Agreement or the Specifications. If any Product is recalled as a result of the supply by DSM of Product that does not conform to the Specifications or other Product requirements of this Agreement, then subject to Sections 4.2.6 and 5.5, DSM shall promptly reimburse OMEROS for its reasonable expenses incurred as a result of such recall, and, at OMEROS’ election, either refund OMEROS for any amounts paid and cancel any amounts payable pursuant to outstanding Purchase Orders under this Agreement relating to the recalled Product or replace the recalled Product with conforming Product at no cost to OMEROS. If OMEROS elects to utilize a Third Party to conduct a recall, OMEROS shall so notify DSM. Upon the occurrence of a Product recall event, OMEROS shall have the right to suspend Monthly Forecasts for the Product that is the subject of the recall and neither Party shall be subject to Firm Purchase Commitments related to the recalled Product until the cause of such recall has been identified and a corrective action plan mutually agreed upon by OMEROS and DSM has been implemented.

The Party responsible for causing a recall of Product shall bear the expenses of the recall. If each Party is partially responsible for causing the recall, the Parties will share the expenses of the recall in proportion to their respective responsibility.

OMEROS or its designated Third Party contractor shall maintain records of all sales of Commercial Product and customers sufficient to adequately administer a recall for the longer of (a) a period of [†], (b) a period of [†] and (c) such other period as required by Applicable Law. Subject to Sections 9.1, 9.2 and 9.3, OMEROS shall in all events be responsible for conducting any recalls of Product.

Over-Labeling. DSM shall not be responsible for reimbursing OMEROS for Product recalls that result directly from over-labeling or re-labeling of Product that is performed by OMEROS or any Third Party, after Product has been delivered by DSM to OMEROS. OMEROS shall indemnify and hold DSM harmless from any liability directly related to such over-labeling.

Validation.

DSM shall prepare equipment qualification and manufacturing validation procedures, and shall perform qualification of equipment and utilities as well as validation of the manufacturing, packaging and cleaning processes in accordance with such procedures.

The Parties recognize that the Validation Batches are being manufactured in part to validate their manufacturability and conformity to the Specifications. Therefore, any part of the Validation Batches that the Parties determine does not meet the Specifications shall not be subject to the warranty contained in Section 5.1 or to the claims procedures set forth in Section 13; and, unless such nonconformity is due to the breach of this Agreement, negligence, willful misconduct or fault of DSM, OMEROS shall pay DSM the full Product Price for such non-conforming Validation Batches pursuant to Section 8.1. OMEROS shall not pay DSM for Validation Batches that do not meet the Specifications due to the breach of this Agreement, negligence, willful misconduct or fault of DSM.

Such employees shall be bound by the confidentiality obligations set forth in Article 15 with respect to DSM Confidential Information and any confidential information of Third Party obtained while at DSM’s facilities and shall also comply with all relevant DSM policies and procedures of which DSM makes such employees aware including, but not limited to, DSM’s security and alcohol and drug policies. OMEROS shall be solely responsible for any direct or indirect costs of such employees.

Term. Unless sooner terminated pursuant to the terms hereof or otherwise extended by mutual written agreement of the Parties, the term of this Agreement shall commence on the Effective Date and shall continue in force and effect until December 31, 2015 (the “Initial Term”).

Termination by Mutual Agreement. This Agreement may be terminated at any time upon mutual written agreement between the Parties.

Termination for Default. This Agreement may be terminated by either Party in the event of the material breach or default by the other Party of this Agreement, provided that the non-breaching Party shall first give to the defaulting Party written notice of the proposed termination or cancellation of this Agreement, specifying the grounds therefor. Upon receipt of such notice, the breaching Party shall have thirty (30) days to respond by either curing such default; or by delivering to the other Party a certificate that such breach is not capable of being cured within such thirty (30) days and that the breaching Party requires additional time and is working diligently to cure such breach; provided, however, that in no event shall the time period for curing such a breach exceed ninety (90) days from receipt of the notice of breach. If the breaching Party does not so respond to the notice of breach or fails to work diligently and to cure such breach within the additional time set forth in this Section 11.3, then the non-breaching Party may terminate

Bankruptcy; Insolvency. Either Party may terminate this Agreement upon the occurrence of either of the following:

The entry of a decree or order for relief by a court having jurisdiction in respect of the other Party in an involuntary case under the Federal Bankruptcy Code, as now constituted or hereafter amended, or under any other applicable federal or state insolvency or other similar law and the continuance of any such decree or order is unstayed and in effect for a period of sixty (60) consecutive days; or

The filing by the other Party of a petition for relief under the Federal Bankruptcy Code, as now constituted or hereafter amended, or any other applicable federal or state insolvency or other similar law.

Termination by OMEROS. OMEROS may terminate this Agreement unilaterally and upon written notice to DSM pursuant to:

the second paragraph of Section 5.1;

Section 5.6.1;

Section 6.8.3; or

in the event that a Regulatory Authority withdraws Product Approval of the Product in the Territory.

Termination by DSM. DSM may terminate this Agreement unilaterally (i) pursuant to Section 6.5 or 8.2.3 upon written notice to OMEROS, or (ii) in the event that DSM is prohibited by mandate of a Regulatory Authority from continuing Manufacturing at the [†] facility due to regulatory requirements and the Parties cannot agree on the terms for the transfer of the Product to another DSM facility. For the avoidance of doubt, DSM will endeavor to supply Product to Omeros through the expiration of the Term and the termination right set forth in subsection (ii) above shall only apply if DSM is prohibited from continuing such manufacture through the length of the Term by the mandate of a Regulatory Authority. Moreover, in the event of termination pursuant to subsection (ii), the effective date of termination shall be the date that DSM is actually prohibited from manufacturing Product at the [†] facility.

Consequences of Expiration and Termination. Upon expiration or termination of this Agreement by either Party:

Except for cases of termination by OMEROS pursuant to Section 11.3 or 11.5, DSM shall Manufacture and deliver, and OMEROS shall purchase in accordance with the provisions hereof, any and all quantities of Product ordered by OMEROS in a Purchase Order prior to the date on which such notice is given. OMEROS, in its sole election, may cancel any quantities of Product already ordered in a Purchase Order, subject to payment of the applicable Cancelled Production Fee.

DSM shall return to OMEROS all unused quantities of Active Pharmaceutical Ingredient in DSM’s possession that have been provided by OMEROS hereunder.

The Parties shall promptly agree on a procedure that allows OMEROS to take possession of any equipment located at DSM’s facility that is owned by OMEROS (with OMEROS paying all reasonable, actual costs to access and remove such equipment, including DSM’s reasonable and directly related facility restoration costs), or, at DSM’s option and with OMEROS’ consent, DSM may purchase such equipment from OMEROS by paying OMEROS the book value thereof as depreciated on a straight-line basis based on average years of usable life.

OMEROS shall purchase from DSM (a) at DSM’s Acquisition Cost plus the lesser of [†], all Active Pharmaceutical Ingredients, Excipients and other materials acquired by DSM hereunder in reasonable reliance upon OMEROS’ forecasts, (b) all work-in-progress for the Product at DSM’s cost, and (c) all other Commercial Product then in DSM’s possession; and (d) OMEROS shall compensate DSM for (i) all other non-cancellable commitments to Third Parties made by DSM to satisfy existing Purchase Orders, and (ii) all Obsolete Stock for which OMEROS has not reimbursed DSM in accordance with Section 6.7. Notwithstanding the foregoing, if any Cancelled Production Fee amount is less than an actual expense for such commitment (including restocking fees for returnable materials), OMEROS shall be required to reimburse DSM solely for the amount of the Cancelled Production Fee rather than for the applicable expense.

Survival. Upon expiration or termination of this Agreement, the obligations of the Parties under the following provisions shall survive in accordance with their terms: Article 1; Sections 4.1.5, 4.2.2, 4.2.6, 5.1 and 5.2 with respect to Product delivered pursuant to Section 11.7; 5.5, 7.2 and 8.4 with respect to Product delivered pursuant to Section 11.7; Article 9; Sections 10.6.1, 11.7 and 11.8; Section 12.1 (inclusive of Sections 12.1.1 and 12.2.2), Article 13 (except that, to the extent applicable, DSM shall be under no obligation to replace non-conforming Product with conforming Product under Section 13.1.4), Articles 14 and 15; Sections 16.1, 16.4 to 16.6; Articles 18, 19 and 20; Sections 21.1, 21.2, and 21.5 to 21.13.

If OMEROS terminates this Agreement prior to the expiration of the Term, if DSM terminates this Agreement prior to expiration of the Term, or in connection with the end of the Term, and upon the written request of OMEROS, DSM agrees to use its commercially reasonable best efforts to provide OMEROS or its designee with all reasonably required assistance in order to transfer the then-current process for Manufacturing each applicable Product, at Omeros’ sole discretion and at Omeros’ sole expense, to not more than one manufacturer designated by OMEROS solely for the purpose of manufacturing such Product for OMEROS or its Affiliates or licensees (a "Technology Transfer"). All assistance provided by DSM shall be at DSM’s standard consulting rates then in effect. Following DSM’s receipt of such request, the Parties will establish, in good faith, a reasonable schedule and plan for completing such Technology Transfer and DSM will thereafter cooperate with OMEROS in implementing such plan,

make available to OMEROS’ designee, subject to any regulatory obligations and confidentiality obligations to Third Parties, copies of current versions of all Controlled Documents applicable to the Product, all Intellectual Work Product developed under this Agreement, but excluding all DSM Intellectual Property and DSM Intellectual Work Product, in each case to the extent relevant to the Manufacturing of Product and any other documentation then in the possession of DSM (excluding DSM Confidential Information) that is reasonably necessary to enable OMEROS’ designee to Manufacture the applicable Product(s) in accordance with the Specifications; and

provide such other assistance as OMEROS may reasonably request to accomplish the Technology Transfer in an effective manner.

In addition to the Technology Transfer contemplated by Section 12.1, OMEROS may at any time request that the Manufacture of the Product be transferred to another manufacturing site owned by DSM. Any such transfer shall be subject to DSM having the capacity to manufacture at another manufacturing site owned by DSM and mutually agreed upon terms including, inter alia¸ (i) the terms and allocation of costs related to the transfer, (ii) revised terms related to the Manufacture of the Product at a different DSM manufacturing site including any appropriate amendments to this Agreement or a superseding agreement to this Agreement, and (iii) revised pricing for the Manufacture of the Product at a different DSM manufacturing site. Neither party will be obligated to provide such assistance if mutually agreed terms are not reached between the parties.

Claims.

In the event that any of the Product delivered to OMEROS’ designated carrier by DSM fails to conform with the Product Specifications, OMEROS shall reject such Product by giving written notice to DSM within [†] after OMEROS’ receipt of such Product and all associated quality assurance documents, including, without limitation, the Product Certificate of Analysis; provided, however, that if such a claim relates to a Latent Product Defect, then subject to and without limitation of Section 13.2, such claim shall be timely if made within [†] following the discovery of such Latent Product Defect.

For any claim relating to the container or container closure system for Products utilizing glass containers packaged by DSM, OMEROS shall make the subject vials available to DSM for analysis.

Claims relating to invoiced quantities or pricing shall be provided to the other Party within [†] following the date of the original invoice stating such quantities or prices, after which period such claims shall be deemed to have been waived; provided, however, that if such a claim relates to a Latent Product Defect, then subject to and without limitation

Any notice given under this Article 13 shall specify the manner in which the Product fails to meet DSM’s warranty or the Specifications. If it is determined by agreement of the Parties (or in the absence of agreement of the Parties, by a mutually acceptable independent laboratory or consultant whose fees shall be paid by the non-prevailing Party), that the non-conformity is due to damage to the Product caused by OMEROS or its agents or a Third Party other than DSM or a subcontractor or vendor under DSM’s control, then DSM shall have no liability to OMEROS with respect thereto. Otherwise, DSM shall promptly, at OMEROS’ election in its sole discretion, (a) credit OMEROS’ account for, or refund to OMEROS, the price invoiced for such non-conforming Product as well as the Acquisition Costs (or, if applicable, pre-agreed designated costs) of the Active Pharmaceutical Ingredients and any other materials supplied by OMEROS to DSM under this Agreement that were used in the Manufacture of such non-conforming Product, together with all out-of-pocket expenses (including, without limitation, all shipping charges) associated with the purchase and return of the non-conforming Product, or (b) promptly replace the non-conforming Product with conforming Product at no cost to OMEROS.

Waiver of Claims. SUBJECT TO ARTICLE 14, CLAIMS ARISING HEREUNDER SHALL BE DEEMED TO HAVE BEEN WAIVED IF NOT BROUGHT WITHIN [†] FOLLOWING THE DATE OF THE OCCURRENCE GIVING RISE TO THE CLAIM, EXCEPT FOR CLAIMS RELATING TO LATENT PRODUCT DEFECTS WHICH CLAIMS SHALL BE DEEMED WAIVED IF NOT BROUGHT WITHIN [†] FOLLOWING DISCOVERY OF SUCH LATENT PRODUCT DEFECT, BUT IN NO CASE LATER THAN [†]. CLAIMS RELATING TO INVOICED QUANTITIES OR PRICING SHALL BE PROVIDED TO THE OTHER PARTY WITHIN [†] FOLLOWING THE DATE OF THE ORIGINAL INVOICE STATING SUCH QUANTITIES OR PRICES, AFTER WHICH PERIOD SUCH CLAIMS SHALL BE DEEMED TO HAVE BEEN WAIVED.

Disposition of Non-conforming Product. In any case where OMEROS expects to make a claim against DSM with respect to damaged or otherwise non-conforming Product, OMEROS shall not dispose of such Product without written authorization and instructions of DSM either to dispose of the Product or to return the Product to DSM.

Product Holds/Rejects. DSM shall promptly notify OMEROS of Product holds and/or rejects that may have an impact on Manufacturing and that may require OMEROS’ approval prior to resolution.

Indemnification by OMEROS. OMEROS shall indemnify, defend and hold DSM, its Affiliates and their respective directors, officers, employees, agents, successors and assigns, harmless from and against any and all damages, judgments, claims, suits, actions, liabilities, costs and expenses (including, but not limited to, reasonable attorneys’ fees) arising out of or in connection with:

any Third Party claim of illness, injury, or death caused by the use of any Product supplied by DSM hereunder that conformed to the Specifications and the other terms of this Agreement at the time of delivery to OMEROS, excluding such claims arising from a Latent Product Defect attributable to DSM’s breach of this Agreement;

any claim by any employee of DSM, its subcontractors, or any Third Party of illness, injury or death arising out of OMEROS’ breach of Section 2.4;

any proceeding instituted by or on behalf of a Third Party based upon a claim that the manufacture, use or sale of the Product infringes a United States patent or any other proprietary rights claimed by OMEROS and utilized with OMEROS’ consent by DSM in the Manufacture of the Product; or

any act or omission of negligence, gross negligence, or willful misconduct by OMEROS or its respective directors, officers, employees, agents, or representatives in the performance of this Agreement.

Indemnification by DSM. DSM shall indemnify, defend and hold OMEROS, its Affiliates and their respective directors, officers, employees, agents, successors and assigns harmless from and against any and all damages, judgments, claims, suits, actions, liabilities, costs and expenses (including, but not limited to, reasonable attorneys’ fees) arising out of or in connection with:

DSM’s breach of this Agreement;

any Third Party claim of illness, injury or death caused by the use of any Product manufactured by DSM hereunder that did not conform to the Specifications or other terms of this Agreement at the time of delivery to OMEROS;

any proceeding instituted by or on behalf of a Third Party based upon a claim that the Manufacture of the Product infringes a United States patent or any other proprietary rights claimed by DSM (except for such claims as are subject to indemnity by OMEROS pursuant to Section 14.1.4); or

any act or omission of negligence, gross negligence, or willful misconduct by DSM or its respective directors, officers, employees, agents, or representatives in the performance of this Agreement.

Indemnification Procedures. A Party (the “Indemnitee”) which intends to claim indemnification under this Article 14 shall promptly notify the other Party (the “Indemnitor”) in writing of any action, claim or other matter in respect of which the Indemnitee or any of its Affiliates, or any of their respective directors, officers, employees or agents intend to claim such indemnification; provided, however, the failure to provide such notice within a reasonable period of time shall not relieve the Indemnitor of any of its obligations hereunder except to the extent the Indemnitor is prejudiced by such failure. The Indemnitee, its Affiliates, and their respective directors, officers, employees and agents shall cooperate fully with the Indemnitor and its legal representatives in the

During the Term and for a period of twenty (20) years following expiration or termination of this Agreement, each of OMEROS and DSM agrees not to publish, disclose or use for any purpose other than its performance under this Agreement, any information disclosed by the other Party and designated as proprietary or confidential (“Confidential Information”), including, without limitation, information printed on hard copy or stored on electronic media, audio or video tapes and disks, or information or knowledge visually acquired by or generated by OMEROS or DSM personnel in the form of written notes and memoranda memorializing information or knowledge acquired visually or aurally in the course of either Party’s performance under this Agreement; provided, however, that for purposes of this Agreement, all OMEROS Intellectual Property and OMEROS Intellectual Work Product shall be deemed OMEROS’ Confidential Information, and all DSM Intellectual Property and DSM Intellectual Work Product shall be deemed DSM’s Confidential Information, regardless of which Party discloses such information to the other Party.

Both Parties agree that the following shall not be considered Confidential Information subject to this Agreement:

information that the Receiving Party can establish with written documentation is in the public domain by publication or otherwise, provided that such publication is not in violation of this Agreement or any other confidentiality agreement;

information that the Receiving Party can establish with written documentation was in the Receiving Party’s possession prior to the time of disclosure by the Disclosing Party and was not acquired, directly or indirectly, from the Disclosing Party;

information the Receiving Party can establish with written documentation was lawfully received from a Third Party; provided, however, that such Third Party was not obligated to hold such information in confidence;

information that the Receiving Party can establish with written documentation was independently developed by the Receiving Party without access or reference to any Confidential Information; and

information that the Receiving Party is compelled to disclose by a court, administrative agency, Regulatory Authority or other tribunal; provided however, that in such case the Receiving Party shall immediately give as much advance notice as feasible to the Disclosing Party to enable the Disclosing Party to exercise its legal rights to prevent and/or limit such disclosure. In any event, the Receiving Party shall disclose only that portion of the Confidential Information that, in the opinion of the Receiving Party’s legal counsel, is legally required to be disclosed and will exercise reasonable best efforts to ensure that any such information so disclosed will be accorded confidential treatment by said court, administrative agency, Regulatory Authority or tribunal.

Subject to Section 16.4, all Confidential Information shall remain the property of the Disclosing Party. Upon the expiration or termination of this Agreement, or at any time upon the written request of the other Party, the Receiving Party shall immediately return or destroy any Confidential Information of the Disclosing Party in the Receiving Party’s possession, custody or control, except that the Receiving Party’s legal counsel may keep one (1) copy for archival purposes. The Disclosing Party’s failure to request the return of Confidential Information shall not relieve the Receiving Party of its confidentiality obligations under this Agreement.

Each Party acknowledges and expressly agrees that the remedy at law for any breach by it of the terms of this Article 15 shall be inadequate and that the full amount of damages that would result from such breach are not readily susceptible to being measured in monetary terms. Accordingly, in the event of a breach or threatened breach by either Party of this Article 15, the other Party shall be entitled to seek immediate injunctive relief prohibiting any such breach and requiring the immediate return of all Confidential Information. The remedies set forth in this Section 15.4, shall be in addition to any other remedies available for any such breach or threatened breach, including the recovery of damages from the breaching Party.

The terms and conditions of this Agreement, but not the fact of its existence, shall constitute Confidential Information, except that either Party may disclose such terms and conditions to its Affiliates in accordance with Section 15.1; provided, however, that notwithstanding the foregoing, the Parties acknowledge that each Party may be required to (and in such instance shall be permitted to) disclose the terms of this Agreement pursuant to its reporting obligations under the Securities Exchange Act of 1934, as amended (or other securities exchange requirements), and to file a copy of this Agreement as an exhibit to a periodic, quarterly or annual report required to be filed by such Party thereunder; provided, that the Party filing a copy of this Agreement as permitted by this Section 15.5 shall seek confidential treatment of the confidential terms of this Agreement, including but not limited to payment terms.

Pre-Existing Intellectual Property. Any intellectual property rights and/or intellectual property owned by a Party or licensed by a Third Party to a Party as of the Effective Date, including, as the case may be, OMEROS Intellectual Property and DSM Intellectual Property (but only to the extent such OMEROS Intellectual Property or DSM Intellectual Property, as applicable, existed as of the Effective Date) (“Pre-Existing IPR”) shall remain the sole and absolute property of the Party that owned or was licensed to use such Pre-Existing IPR. Nothing in this Agreement shall act as any assignment or transfer of the Pre-Existing IPR. The Pre-Existing IPR shall not be licensed to the other Party under this Agreement except as expressly provided for in Sections 16.2 and 16.3.

License Grants to DSM. OMEROS hereby grants to DSM a royalty-free, worldwide, nonexclusive license (without the right to sublicense) to practice the OMEROS Intellectual Property and OMEROS Intellectual Work Product solely to the extent necessary or reasonably useful for DSM to perform its obligations hereunder. The foregoing nonexclusive license shall terminate upon the termination or expiration of this Agreement. Nothing in the foregoing license grant shall permit DSM to make any disclosure of OMEROS’ Confidential Information or OMEROS Intellectual Property to a Third Party without the express prior written consent of OMEROS. This license does not prevent OMEROS from granting a license to or making use of the OMEROS Pre-Existing IPR, OMEROS Intellectual Property or OMEROS Intellectual Work Product for other purposes.

License Grants to OMEROS. DSM hereby grants to OMEROS (i) during the Term, a royalty-free, irrevocable, worldwide, nonexclusive, sublicensable license, but without the right to sublicense to any competing manufacturer without obtaining DSM’s consent, to practice the DSM Intellectual Property and DSM Intellectual Work Product solely to the extent necessary or reasonably useful for Manufacturing Product and (ii) a royalty-free, worldwide, exclusive, sublicensable right of reference to the drug master file(s) for Product(s) prepared and maintained by DSM pursuant to this Agreement. This license does not prevent DSM from granting a license to or making any use of the DSM Intellectual Property or DSM Intellectual Work Product for any purpose.

Ownership of Intellectual Work Product.

OMEROS acknowledges that DSM shall be the sole and exclusive owner of all Intellectual Work Product [†] (“DSM Intellectual Work Product”).

DSM acknowledges that OMEROS shall be the sole and exclusive owner of all Intellectual Work Product [†] (“OMEROS Intellectual Work Product”), and agrees promptly to disclose to OMEROS in writing any OMEROS Intellectual Work Product that DSM may develop solely or jointly during the Term. DSM hereby irrevocably assigns and transfers to OMEROS (and to the extent that an executory assignment is not enforceable, DSM hereby agrees to assign and transfer to OMEROS, in writing, from time to time, upon request) all of the right, title and interest that DSM has or may later acquire in and to the OMEROS Intellectual Work Product under copyright, patent, trade

Right to File for Protection.

OMEROS shall have the sole right to prepare, file, prosecute and maintain patent applications and patents, continuations, continuations-in-part, divisions, reissues, additions, renewals, or extensions thereof, and all other applications considered desirable by OMEROS, disclosing or claiming the OMEROS Intellectual Work Product, in countries and regions of its choice throughout the world, for which OMEROS shall bear all costs. Either before or after the termination of this Agreement, DSM shall reasonably assist OMEROS in acquiring and maintaining such rights in, and confirming OMEROS’ title to, the OMEROS Intellectual Work Product, at the request and sole expense of OMEROS. The assistance of DSM shall include but not be limited to executing assignments, declaration or other documents related to all patent, copyright, trademark and other applications considered desirable by OMEROS, cooperating in legal proceedings, and taking any other reasonable steps considered desirable by OMEROS.

DSM shall have the sole right to prepare, file, prosecute and maintain patent applications and patents, continuations, continuations-in-part, divisions, reissues, additions, renewals, or extensions thereof, and all other applications considered desirable by DSM, disclosing or claiming the DSM Intellectual Work Product, in countries and regions of its choice throughout the world, for which DSM shall bear all costs. Either before or after the termination of this Agreement, OMEROS shall assist DSM in acquiring and maintaining such rights in, and confirming DSM’s title to, the DSM Intellectual Work Product, at the request and sole expense of DSM.

All rights and licenses granted under or pursuant to this Article 16 by DSM are, and shall otherwise be deemed to be, for purposes of Section 365(n) of the United States Bankruptcy Code or analogous provisions of Applicable Law outside the United States, license of rights to “intellectual property” as defined under Section 101 of the United States Bankruptcy Code or analogous provisions of foreign law. DSM hereby agrees that in the event of the commencement of a bankruptcy proceeding by or against DSM under the United States Bankruptcy Code or analogous provisions of Applicable Law outside the United States, OMEROS, as licensee of such rights under this Agreement, shall retain and may fully exercise all of its rights and elections thereunder. In addition, in the event of such proceedings, OMEROS shall be entitled to a complete duplicate or (or complete access to, as appropriate) any such intellectual property and all embodiments of such intellectual property which, if not already in OMEROS’ possession, shall be promptly delivered to it upon any such commencement of a bankruptcy proceeding upon OMEROS’ written request therefor.

Effects of Force Majeure. Neither Party shall be held liable or responsible for failure or delay in fulfilling or performing any of its obligations under this Agreement if such failure or delay is due to any condition beyond the reasonable control of the affected Party including, without limitation, Acts of God, strikes or other labor disputes, war, riot, earthquake, tornado, hurricane, fire, civil disorder, explosion, accident, flood, sabotage, lack of or inability to obtain adequate fuel, power, materials, labor, containers, transportation, supplies or equipment, breakage or failure of machinery or apparatus, national defense requirements, or supplier strike, lockout or injunction (a “Force Majeure Event”). In the event that DSM is unable to meet Purchase Order Delivery Dates because of any Force Majeure Event for more than [†], OMEROS may (a) terminate this Agreement without penalty on [†] notice to DSM and (b) cancel any and all outstanding Purchase Orders. In addition, during the continuation of any Force Majeure Event, OMEROS shall be free to source its requirements for Product from Third Parties with respect to any Purchase Order as to which DSM is unable to meet the specified Delivery Dates because of the Force Majeure Event. Any Firm Purchase Commitment and all other minimum purchase requirements shall be reduced, without penalty, by the quantity of Product covered by any Purchase Orders cancelled pursuant to this Section 17.1. Upon cessation of such Force Majeure Event, the Parties shall promptly resume performance on all Purchase Orders which have not been terminated.

Notice of Force Majeure Event. In the event either Party is delayed or rendered unable to perform due to a Force Majeure Event, the affected Party shall give notice thereof and its expected duration to the other Party promptly after the occurrence of the Force Majeure Event; and thereafter, the obligations of the affected Party will be suspended during the continuance of the Force Majeure Event. The affected Party shall take commercially reasonable steps to remedy the Force Majeure Event with all reasonable dispatch, but such obligation shall not require the settlement of strikes or labor controversies on terms unfavorable to the affected Party.

Legal Compliance. Each Party shall comply in all material respects with all Applicable Law in the performance of its obligations pursuant to this Agreement.

Press Releases. Any press release, publicity or other form of public written disclosure related to this Agreement prepared by one Party shall be submitted to the other Party prior to release for approval, which approval shall not be unreasonably withheld or delayed by such other Party; provided, however, that OMEROS and DSM’s parent company may announce the signing of this Agreement and the names of the Parties hereto (but none of the terms herein) in their quarterly results release without such prior approval.

Joint Press Release. Following the Effective Date, the Parties will agree to issue a joint press release, the form and content of which shall be mutually agreed by the Parties with respect to the transactions contemplated by this Agreement and which shall note

Notwithstanding the above, as required by Applicable Law, OMEROS, DSM and their respective Affiliates shall be permitted to use the other Party’s name and to disclose the existence and terms of this Agreement in connection with securities or other public filings subject to the protections of confidential information as set forth in Section 15.5.

Arbitration. The Parties recognize that a bona fide dispute as to certain matters may from time to time arise during the term of this Agreement that relates to either Party’s rights and/or obligations hereunder. In the event of the occurrence of such a dispute, either Party may, by notice to the other Party, have such dispute referred to their senior officers as shall be designated by each Party for attempted resolution through good faith negotiations within thirty (30) days after such notice is received. In the event the designated officers are not able to resolve such dispute within such thirty (30) day period, or such other period of time as the Parties may mutually agree in writing, the Parties shall be obligated to submit the dispute to binding arbitration in accordance with the rules of the American Arbitration Association (“AAA”) for commercial arbitration, utilizing three (3) arbitrators mutually agreeable to the Parties. If the Parties are unable to reach agreement as to one or more of the arbitrators, the arbitrators shall be chosen in accordance with the AAA commercial arbitration rules. The arbitrators shall present a detailed written statement of their findings; and the Parties shall be bound thereby. The arbitration proceedings and any documents or other information disclosed in connection therewith shall be subject to the requirements of confidentiality as set forth in Article 15.

Assistance from OMEROS. To assist DSM in its performance of this Agreement, OMEROS shall provide DSM, in a timely fashion, with all relevant information, documentation and data (including without limitation any information, documentation and data relating to product safety and information, documentation and data, including without limitation NDA and/or other OMEROS Regulatory Documentation numbers and NDC codes, reasonably necessary for DSM to drug list a Product) that is necessary or appropriate for DSM’s performance hereunder. If requested by DSM to provide such information, OMEROS shall provide such information (or an explanation of the legitimate reason for any delay and a projected date by which such support or information will be provided) within ten (10) business days of DSM’s request. In the event OMEROS is to review or approve any information, documentation, data or samples prepared or supplied by or on behalf of DSM, it shall complete such review and approval process within in a timely fashion.

Assignment; Subcontractors. Without the prior written consent of the other Party, such consent not to be unreasonably withheld, conditioned, or delayed, neither Party shall sell, transfer, assign, delegate, pledge, or otherwise dispose of, whether voluntarily, involuntarily, by operation of law or otherwise, this Agreement or any of its rights or duties hereunder; provided, however, that either Party may make such an assignment without the other Party’s consent to its Affiliate or to a successor, whether in a merger, sale of stock, or sale of assets to which this Agreement pertains and provided, further, that OMEROS may make such an assignment without DSM’s consent to a Third Party to which OMEROS grants commercialization rights to Product in the Territory. With respect to an assignment to an Affiliate, the assigning Party shall remain responsible for the performance by such Affiliate of the rights and obligations hereunder. Any attempted assignment or delegation in violation of this Section 21.4 shall be void and of no effect. All validly assigned and delegated rights and obligations of the Parties hereunder shall be binding upon and inure to the benefit of and be enforceable by and against the successors and permitted assigns of DSM or OMEROS as the case may be. In the event either Party seeks and obtains the other Party’s consent to assign or delegate its rights or obligations to another Party, the assignee or transferee shall assume all obligations of its assignor or transferor under this Agreement. DSM may, only with OMEROS’ prior written consent at Omeros’ reasonable discretion, utilize subcontractors to perform any part of this Agreement.

Continuing Obligations. Termination, assignment or expiration of this Agreement shall not relieve either Party from full performance of any obligations incurred prior thereto.

Waiver. Neither Party’s waiver of any breach or failure to enforce any of the terms and conditions of this Agreement, at any time, shall in any way affect, limit or waive such Party’s right thereafter to enforce and compel strict compliance with every term and condition of this Agreement.
