6.3Purchase Orders. From time to time, Partner may issue purchase orders for manufacturing of volumes of Product (each, a “Purchase Order”) consistent with the Rolling Forecast. For each month, Partner shall submit Purchase Orders for at least the Commitment Amount corresponding to the first month of the most recent Binding Forecast for delivery in such month concurrently with the Rolling Forecast (i.e., at least [***] prior to the beginning of each month). Partner may submit additional Purchase Orders from time to time. Each such Purchase Order shall specify: (i) the quantity of each Product desired, (ii) the destination of Delivery, and (iii) the requested Initiation Date (defined below) (to the extent known by Partner and subject to change by the Partner within the same Calendar Quarter for the Products under such Purchase Order (which shall comply with Section 6.5). Once a Purchase Order is accepted by Cellares, the Purchase Order is non-cancelable by Partner or Cellares and no changes may be made to the Purchase Order by either Party without written consent by the other Party.

6.4Acceptance of Purchase Orders.

(a)No later than [***] after receipt of a Purchase Order, Cellares shall confirm in writing its receipt of the Purchase Order, provided that (1) if (i) the type and quantity of Products described in a Purchase Order are consistent with the most recent Binding Forecast, (ii) the quantities of such Products described in such Purchase Order are no more than (when aggregated with all other Purchase Orders for the applicable Calendar Quarter) [***] of the Commitment Amount, (iii) the requested Initiation Dates of such Products complies with the lead-time requirements described in Section 6.5, and (iv) the Purchase Order otherwise complies with the terms of this Agreement, then Cellares shall accept such Purchase Order by sending an acknowledgement to Partner (any such accepted or deemed accepted Purchase Order, a “Confirmed Order”) and (2) Cellares may reject the portion of any Purchase Order covering any Calendar Quarter outside the Binding Forecast or in excess of (when aggregated with all other Purchase Orders for the applicable Calendar Quarter) [***] of the quantity set forth in the Binding Forecast. Any Purchase Order that is compliant with (i) - (iv) above but not accepted in writing by Cellares within [***] after its receipt thereof shall be deemed accepted. Any Purchase Order that is not compliant with (i) - (iv) above but not accepted in writing by Cellares within [***] after its receipt thereof shall be deemed rejected.

(b)Subject to the foregoing, Cellares shall use commercially reasonable efforts (but shall otherwise have no obligation) to accommodate Purchase Orders for quantities of Products that in the aggregate with all other Purchase Orders for the applicable Calendar Quarter exceed [***] but are no more than [***] of the Commitment Amount for the applicable Calendar Quarter. Cellares shall notify Partner whether or not Cellares will agree to supply the additional amount of Products requested in any such Purchase Order, the estimated Delivery Dates for such excess Product, and if the remainder of such

Purchase Order is acceptable in accordance with this Section 6.4, then upon such written notice, such additional amount of Products accepted by Cellares shall be included in the Confirmed Order. Cellares shall not be considered to have accepted any Purchase Order for such additional Product quantities without written confirmation. Cellares shall have no obligation to accommodate any Purchase Orders for quantities of Products that in the aggregate exceed [***] of the Commitment Amount.

6.5Lead Time; Delivery Date. Partner will issue Purchase Orders that specify requested date(s) of initiation of manufacturing (the “Initiation Date”), and Cellares’ written confirmation of Purchase Orders (if any) shall set forth a delivery date for each Product ordered (the “Delivery Date”). For each Product, the time between the Initiation Date and the Delivery Date shall be not less than the lead time as specified in the applicable SOW, unless otherwise agreed by Cellares. Cellares shall use [***] to comply with any maximum turnaround time specified in the applicable SOW. The Initiation Date and Delivery Date for each Product shall be binding on Cellares once such Purchase Order is accepted by Cellares unless otherwise mutually agreed; provided that, in the event Cellares reasonably anticipates that it will be unable to meet any Initiation Date or Delivery Date for any accepted Purchase Order due to circumstances outside of Cellares’ control, Cellares shall promptly notify Partner and the Parties shall work together in good faith to find a mutually agreeable alternative Initiation Date or Delivery Date to the extent feasible based on bona fide patient needs.

6.6Failure to Comply with Binding Forecast. Unless otherwise set forth in an applicable SOW, if Partner does not purchase the full quantity of Products in the Commitment Amount during a given Calendar Quarter as set forth in the Binding Forecast, [***].

6.7No Other Terms and Conditions. If a sales acknowledgment, invoice, Purchase Order, or other document submitted by either Party contains terms or conditions conflicting with or additional to the terms and conditions of this Agreement, the Parties hereby reject such terms and conditions, and the terms and conditions of this Agreement shall prevail unless otherwise expressly agreed to in writing by both Parties.

6.8Supply Shortfall; Minimum Capacity Guarantee.

(a)Supply Shortfall. In the event Cellares’ reasonably believes its manufacturing capacity will be insufficient to supply the Commitment Amount of Product, Cellares shall have the right to allocate its manufacturing capacity (including raw materials) between Partner and Cellares’ other customers [***].

(b)Minimum Capacity Guarantee. Notwithstanding anything herein to the contrary, provided that Partner complies with the forecasting structure set forth above (as may be amended from time to time in writing), Cellares shall provide Partner with manufacturing capacity, [***]: (i) [***], or (ii) [***].

7.Pricing; Payment.

7.1Service Fees. Partner will pay Cellares the fees and other costs for all Services properly performed (the “Service Fees”) and Product Delivered hereunder (the “Product Price”) (comprised of a Batch fee and Raw Materials pass-through costs as set forth on the applicable SOW) following receipt by Partner of Cellares’ invoices for such Product pursuant to Section 7.3 or as otherwise set forth in the applicable SOW. Unless otherwise expressly set forth in the applicable SOW, all Service Fees are non-refundable. The initial Batch fee is set forth on Exhibit A hereto.

8.1Quality Release. Cellares shall provide to Partner the applicable Batch Records, CoA, CoC and such other documentation for Product as is reasonably required to meet all applicable regulatory requirements of the Regulatory Authorities and completion of other release activities completed per the Quality Agreement upon Delivery (“Release”).

8.2Delivery Without Batch Documentation. Upon Partner’s request, Cellares shall Deliver restricted Product prior to Release, provided that such request must be accompanied by Partner’s written acknowledgement that (a) the Product has been Delivered without a CoA or CoC or other applicable documentation, (b) accordingly, the Product cannot be administered to humans until transmittal of such certificates and documentation, and (c) Partner nevertheless accepts full risk of loss, title and ownership of the Product. Cellares shall have no liability or responsibility for any such Product or the use thereof by or on behalf of Partner provided without the applicable documentation. Cellares shall deliver the CoA, CoC and such other documentation as required pursuant to Applicable Law and the applicable SOW as soon as such documentation is available.

8.3Delivery. All Products shall be delivered EXW (Facility) (Incoterms 2020) (“Deliver,” “Delivered,” or “Delivery,” as appropriate), in each case no later than the Delivery Date specified on Cellares’ written confirmation of the applicable Purchase Order (or, if no such Delivery Date is specified, the Delivery Date shall be consistent with the turnaround time set forth in the applicable SOW and Section 6.5) (unless the Delivery Date is changed by written agreement of the Parties or a Force Majeure occurs). Partner shall be responsible for all loading, transit, export and import from the Facility, including the selection of a carrier and management thereof.

9.Acceptance/Rejection of Product.

9.1Acceptance. Following Delivery of each shipment of Product pursuant to Section 8.3, Partner shall have the right to inspect and test Product to determine compliance with this Agreement, including the Product Warranty (defined below). If Partner believes that any Product in any shipment does not conform to the Product Warranty (“Non-Conformance”), [***]). The mere failure of a Product to have a particular therapeutic or other effect in and of itself shall not be grounds for deeming such Product to have a Non-Conformance. If Partner fails to notify Cellares of a Non-Conformance within the timelines set forth above in this Section 9.1, such Product shall be deemed accepted by Partner.

9.2Rejection and Remedy for Non-Conformance.

(a)Rejection for Non-Conformance. Upon timely receipt of a Deficiency Notice pursuant to Section 9.1, if Cellares believes in good faith that (i) rejected Product complies with the Product Warranty or (ii) such Non-Conformance is attributable to the Partner Manufacturing Process, any specimens, samples, Partner Materials, information, instructions or intellectual property provided by Partner or the inherent properties of such Product (this clause (ii), “Partner Fault”), the Parties shall initiate an investigation of such Non-Conformance which will be conducted, upon mutual agreement of the Parties, by either Party, the Parties jointly, or a Third Party independent laboratory agreed by the Parties, provided that Cellares notifies Partner of its belief that rejected Product complies with the Product Warranty within [***] after receipt of the Deficiency Notice, after which time Cellares shall have waived its right to challenge the rejection. Partner shall provide Cellares with reasonable assistance in such investigation, including the return of all such Non-Conforming Product at Cellares’ expense. If the investigation determines that (i) such Non-Conformance does exist, then the applicable Products shall be deemed to be properly rejected or (ii) such Non-Conformance does not exist or is the result of any Partner Fault or cannot be definitively established, then Partner shall be deemed to have accepted Delivery of such Products (and Partner shall be obligated to pay for such Products as set forth in this Agreement and Partner shall reimburse expenses paid by Cellares pursuant to the immediately preceding sentence). The costs of the investigation related to such Deficiency Notice shall be borne by Partner, unless it is determined by the Parties that a Non-Conformance not resulting from any Partner Fault exists, in which case Cellares shall pay such costs. If the foregoing investigation is conducted by a Third Party independent laboratory as set forth in this Section 9.2(a), the determination by such independent laboratory shall be binding on the Parties, absent manifest error.

(b)Disagreement Regarding Non-Conformance. In the event Partner provides a timely Deficiency Notice and Cellares timely challenges such Deficiency Notice, and following an investigation by either Party or the Parties jointly under Subsection 9.2(a) either Party in good faith disagrees with the determination that the Product was or was not Non-Conforming or whether any Non-Conformance was the result of any Partner Fault, then the Party that disagrees with such determination may cause an independent third-party laboratory agreeable to both Parties to perform comparative tests and/or

analyses on samples of the alleged Non-Conforming Product to determine whether such Product is Non-Conforming and if so, whether such Non-Conformance was the result of any Partner Fault, in which case such laboratory’s results shall be in writing and shall be final and binding on the Parties absent manifest error on the face of its report. Unless otherwise agreed to by the Parties in writing, the costs associated with such third-party testing and review shall be borne by the Party against whom the independent third-party laboratory rules or, if the laboratory does not rule in favor of either Party, then the Parties shall share equally the expenses of the laboratory.

(c)Remedy for Non-Conformance. [***].

9.3Delivery of Non-Conforming Product. Notwithstanding the foregoing, Partner may upon its request take delivery of Non-Conforming Product, or any Product that otherwise does not meet the applicable Specifications or cGMP (including any Development Batch), at Partner’s sole risk and cost. Cellares shall have no liability or responsibility for any such Product or the use thereof by or on behalf of Partner.

10.Confidentiality.

10.1Each Party (a “Disclosing Party”) may disclose or otherwise make available, directly or indirectly, to the other Party (the “Receiving Party”) confidential information of the Disclosing Party (“Confidential Information”) during the term of this Agreement, whether disclosed or otherwise made available hereunder or under the Quality Agreement, whether written, graphic, oral, visual, tangible or intangible, in any form or format. The existence and terms of this Agreement are deemed to be the Confidential Information of both Parties. The Receiving Party shall (a) maintain all Confidential Information in confidence and employ commercially reasonable procedures to prevent its unauthorized publication or disclosure, (b) only disclose Confidential Information to those of its officers, directors, employees, consultants and advisors who have a need to know such Confidential Information for purposes permitted under this Agreement and who are subject to written obligations of confidentiality and non-use at least as protective as those set forth therein (except that each Party may disclose the terms of this Agreement to bona fide actual or prospective underwriters, investors (which are not competitors of Partner), lenders or other financing sources or to potential acquirers of the business to which this Agreement relates, and who in each case have a specific need to know such Confidential Information and who are bound by an obligation of confidentiality and restrictions on use that are at least as protective of the Disclosing Party as those in this Article 10, and (c) Confidential Information of Cellares to Regulatory Authorities solely as contemplated and permitted under Article 5); provided that the Receiving Party shall be liable for any failure to comply with the Receiving Party’s obligations hereunder and use the Confidential Information only for any purposes permitted under this Agreement and the Quality Agreement. Subject to the requirements of the preceding sentence, Partner also may disclose Confidential Information of Cellares to third parties (each, a “Collaboration Partner”) with whom Partner has (or is negotiating) a marketing and/or development collaboration agreement (“Collaboration Agreement”), provided that (i) the specific Collaboration Partner and scope of necessary disclosure is identified to Cellares in advance, and (ii) notwithstanding clause (c) of the preceding sentence, the Collaboration Partner’s use of the Cellares Confidential Information is solely to evaluate and (if executed) to perform the Collaboration Agreement. In addition, if Cellares identifies a Collaboration Partner as a competitor to or customer of Cellares, then the parties will discuss specific ways to mitigate Cellares’ concerns with respect to the disclosure of Cellares Confidential Information in such context. The Receiving Party’s obligations under this Article 10 will survive termination or expiration of this Agreement for a period of [***]; provided that with respect to any trade secret of the Disclosing Party, such obligations shall survive and continue for as long as such Confidential Information qualifies as a trade secret of the Disclosing Party under Applicable Law. Confidential Information shall include any “Confidential Information” as defined under the TTA. For clarity, Partner Background IP, Partner Materials, Partner Arising IP, and the Partner Manufacturing Process are the Confidential Information of Partner, and Cellares Background IP, Cellares Technology and Cellares Inventions are the Confidential information of Cellares.

10.2The Receiving Party’s obligations under this Article 10 shall not apply to any Confidential

Information that, as demonstrated by contemporaneous written evidence, (a) is known to the Receiving Party without obligation of confidentiality at the time it was obtained from the Disclosing Party; (b) is acquired without obligation of confidentiality by the Receiving Party from a third party having a right to so disclose such Confidential Information; (c) is or becomes published or otherwise in the public domain other than by violation of this Agreement by the Receiving Party; or (d) is independently developed by the Receiving Party without reference to or reliance upon the Confidential Information disclosed by the Disclosing Party. The Receiving Party may disclose Confidential Information that it is required to disclose under Applicable Law or an order by a court or other regulatory body having competent jurisdiction (including the rules of any securities exchange); provided that except where not legally permitted, the Receiving Party shall give the Disclosing Party reasonable advance notice of such disclosure requirement and shall cooperate with the Disclosing Party to oppose, limit or secure confidential treatment for such required disclosure. In the event of any such required disclosure, the Receiving Party shall disclose only that portion of the Confidential Information that the Receiving Party is legally required to disclose, and any such Confidential Information required to be disclosed shall remain subject to the obligations of this Article 10 in all other respects.

10.3Cellares will provide Partner with access to an encrypted data storage platform for the transfer, storage, use, or processing of personal data in connection with the applicable SOW. The Receiving Party shall immediately notify the Disclosing Party of any unauthorized disclosure or use Confidential Information and reasonably cooperate with the Disclosing Party in the response thereto. In the event of a conflict between the terms of this Article 10 and the terms of the TTA, the terms of this Agreement shall control.

10.4Each Party expressly agrees that any breach or threatened breach by a Receiving Party of this Article 10 may cause irreparable harm to the Disclosing Party and that money damages may not provide a sufficient remedy to the Disclosing Party for any breach or threatened breach. In the event of any such breach and/or threatened breach, then, in addition to all other remedies available at law or in equity, the Disclosing Party shall be entitled to seek injunctive relief and any other relief deemed appropriate by the Disclosing Party.

11.Intellectual Property.

11.1Background IP. Each Party shall retain ownership of all technology or intellectual property rights owned or controlled by a Party as of the Effective Date or developed by or on behalf of such Party independent of this Agreement (such Party’s “Background IP”), and the other Party shall have no rights in such Party’s Background IP except as expressly provided in this Agreement.

11.2Inventions.

(a)Any Partner Materials and/or Confidential Information of Partner provided to Cellares by or on behalf of Partner in connection with this Agreement, in any form whatsoever, shall remain the sole and exclusive property of Partner (“Partner Property”). Cellares shall not acquire any right, title or interest in the Partner Property as a result of its performance of the Services.

(b)All data, documentation, information, know-how, procedures, discoveries, inventions and/or techniques (“Inventions”) developed by or on behalf of Cellares, solely or jointly with others, in the course of performing the Services that do not rely on and/or are not specifically related to the Product or Partner Property (for clarity, Inventions are not specifically related to the Product or Partner Property where they: (i) are generally applicable to the development or manufacture of chemical or biological products or products components, (ii) relate to or improve Cellares’ Confidential Information or Background IP, including the Manufacturing Process (other than the Partner Manufacturing Process) or

(iii) relate to the conduct of Cellares’ business, Cellares’ products or services or the use of materials in connection therewith) shall be collectively referred to as the “Cellares Inventions” (together with Cellares’ Background IP, the “Cellares Technology”), are and shall remain solely owned by Cellares.

(c)Any Inventions developed by or on behalf of Cellares, solely or jointly with others, in the course of

performing the Services, and which rely on and/or are specifically related to the Product or Partner Property (“Partner Arising IP”) shall be solely owned by Partner, and Cellares hereby assigns to Partner all of Cellares’ right, title and interest in such Partner Arising IP; provided that Cellares shall retain the right to use such Partner Arising IP to the extent necessary to conduct the Services and for Cellares’ internal research and development purposes, subject in each case to the obligations of Cellares under Article 10. Cellares shall, at Partner’s request and expense, use reasonable efforts to assist Partner to obtain, maintain and enforce the patents and other intellectual property covering the Partner Arising IP. Cellares shall ensure that its personnel, Affiliates, subcontractors or agents involved in the performance of the Services assign to Cellares all Partner Arising IP to enable Cellares’ assignment to Partner as described above.

11.3Licenses.

(a)Partner hereby grants to Cellares a limited, non-exclusive, non-sublicensable, royalty-free, fully paid-up license under Partner’s Background IP (to the extent actually disclosed to Cellares hereunder by or on behalf of Partner) and Partner Arising IP solely to the extent necessary to perform the Services.

(b)To the extent any Cellares Technology is incorporated into any Product, Cellares hereby grants to Partner a limited, non-exclusive, worldwide, royalty-free, fully paid-up, sublicensable (solely with Cellares’ prior written consent) and non-transferrable (except as set forth in Section 15.4) license, during the term of this Agreement, under such Cellares Technology solely as necessary for Partner to sell, have sold, offer for sale, import, and otherwise commercialize such Product. For clarity, Partner shall have no license or right to use or authorize the use of any Cellares Technology to make or have made any Product or product or perform or perform or authorize the performance of any services.

11.4Patent Filings. Each Party shall have the right to file and prosecute patents covering inventions to be owned by such Party pursuant to Section 11.2, and the other Party shall reasonably cooperate with the filing Party at the filing Party’s expense. Notwithstanding the foregoing, neither Party shall have the right to disclose any Confidential Information of the other Party in any patent filing without the other Party’s prior consent.

11.5Notice of Infringement; Infringement Claims.

(a) Each Party shall promptly notify the other Party of any claims that any Product, the practice of the Manufacturing Process of the performance of the Services infringes, misappropriates or otherwise violates the valid intellectual property rights of any Third Party. In the event that either Party notifies the other Party of its reasonable belief that the Services infringe, misappropriate or otherwise violate the valid intellectual property rights of any Third Party, then the Parties shall meet to discuss in good faith (x) the existence of such infringement or misappropriation, (y) the risk of a third-party claim based on such potential infringement or misappropriation, and (z) any steps that can be taken (including modifications to the manner of performance of the Services) to mitigate the risk of such a claim.

(b)If a Third Party claim is initiated against Cellares in a court of competent jurisdiction alleging the Product infringes, misappropriates or otherwise violates the valid intellectual property rights of such Third Party (such claim a “Product Infringement Claim,” the applicable country over which the court has jurisdiction, the “Applicable Product Jurisdiction”), then Cellares may suspend the infringing Services for the Applicable Product Jurisdiction by providing Partner with [***] written notice; provided that Cellares: (i) may shorten such notice to [***] in the event that Partner fails to fulfill its obligations under Section 13.2 to defend, indemnify and hold harmless Cellares Indemnitees from and against such Product Infringement Claim and fails to cure within such notice period, and (ii) shall continue performance of the Services for the balance of the Term if the risk of such Product Infringement Claim has been reasonably mitigated (e.g. dismissal,

abandonment or release).

(c)If a Third Party claim is initiated against Cellares in a court of competent jurisdiction alleging the Services (not the Product) infringes, misappropriates or otherwise violates the valid intellectual property rights of such Third Party (such claim a “Services Infringement Claim,” the applicable country over which the court has jurisdiction, the “Applicable Services Jurisdiction”), then subject to the following, Cellares shall use reasonable commercial efforts to revise the Services to render them non-infringing (without materially changing the Services), and/or to secure rights, at Cellares’ cost, to the Third Party claimant’s intellectual property to allow performance to continue. If after using reasonable commercial efforts, Cellares decides in good faith, and based on advice of competent counsel, that it cannot secure either of the foregoing solutions in a reasonably timely manner and/or on commercially reasonable terms, then Cellares may suspend the infringing Services for the Applicable Services Jurisdiction by providing Partner with [***] written notice; provided that Cellares shall continue performance of the Services for the balance of the Term if the risk of such Services Infringement Claim has been reasonably mitigated (e.g. dismissal, abandonment or release).

13.2By Partner. Partner will defend, indemnify and hold harmless Cellares and its Affiliates and their respective directors, officers, employees and agents (“Cellares Indemnitees”) from and against any Losses arising from Claims which may be asserted against such Cellares Indemnitees by Third Parties to the extent arising out of: (a) the research, development, use, sales or distribution by or on behalf of Partner, or any distributor, collaborator, customer, patient, licensee, representative or agent of Partner, of any Product or product containing the Product, (b) any claims alleging that the use of the Partner Property in accordance with Partner’s instructions infringes any intellectual property rights of Third Parties, (c) the gross negligence or willful misconduct of any Partner Indemnitee during the Term, or (d) any injuries suffered by Partner’s employee or representative while at the Facility or elsewhere; except to the extent such Claim is subject to indemnification by Cellares pursuant to Section 13.1.
