To the extent Claims that are based on Provider IP independent of the Services or Product under this Agreement or Provider’s breach of this Agreement, Client shall not be required to defend, indemnify, and hold Provider and its Related Persons harmless from those Losses. Provider shall defend, indemnify and hold Client and its Related Persons harmless from and against Losses resulting from Claims to the extent arising out of or related to infringement of any Intellectual Property rights related to the Services and that are based on Provider IP.

| 9.4 | Defense. Each Party shall notify the other Party within [***] upon learning of a Claim that is subject to indemnification pursuant to Sections 9.1, 9.2, or 9.3 (but failure to notify shall not relieve the indemnifying Party of its indemnification obligations unless such failure materially prejudices its ability to defend the claim). The indemnifying Party shall control, [***], the defense of the Claim [***] with counsel of its choice. The indemnified Party shall use [***] to cooperate in the defense at the indemnifying Party’s request and expense, and may participate in the Claim [***]. No compromise or settlement of any Claim may be made by the indemnifying Party without the indemnified Party’s written consent; provided that, if a settlement contains an absolute waiver of liability for the indemnified party, and each party has acted in compliance with the requirements of this Section 9.4, then the indemnified party’s consent will be deemed given.

10.CONFIDENTIALITY AND PUBLICITY

| 10.1 | Confidentiality. During the term of this Agreement and for [***] thereafter (other than with respect to trade secrets, which shall remain confidential for so long as they are protected under Applicable Law), the Receiving Party shall, and shall ensure that it, its Affiliates, and its Related Persons will, (a) maintain the Confidential Information of the Disclosing Party in confidence, (b) not use the Confidential Information of the Disclosing Party other than solely in connection with this Agreement and (c) not disclose the Confidential Information of the Disclosing Party to any third party other than (i) those of its Related Persons that have a need to know the Confidential Information in connection with the Services and are obligated to maintain the Confidential Information in confidence on terms at least as strict as those contained herein, and (ii) notify the Disclosing Party of any unauthorized disclosure of its Confidential Information [***] upon becoming aware of such disclosure. Notwithstanding the foregoing, Client may disclose the existence of this Agreement and Confidential Information of Provider confidentially in connection with a potential financing or acquisition or collaboration, provided, however, Client shall be liable for the acts and consequences of such disclosure.

| 10.3 | Publicity. Each Party shall not, and shall ensure that its Related Persons will not, use the name, symbols or marks of the other Party or any of its Affiliates in any advertising or publicity material or make any form of representation or statement that would constitute an express or implied endorsement by the other Party or any of its Affiliates of any commercial product or service, without the other Party’s or Affiliate’s prior written consent.

| 10.4 | Audits. Provider and its Affiliates may have in the past provided, and may currently or in the future provide, services to other customers that are similar to the Services.

In order to protect the Confidential Information of Client and the confidential information of other customers, Provider shall use [***] to ensure that other customers do not seek the disclosure of Confidential Information of Client, and Client hereby agrees it shall not seek the disclosure of confidential information of other customers of Provider. Notwithstanding the foregoing, if Client wishes to conduct an audit that relates to services provided to another customer for purposes of confirming that Client's Intellectual Property is adequately protected, then Provider shall use [***] to seek the other customer’s approval to waive confidentiality obligations to the extent necessary to allow Client to conduct the audit in a manner that does not involve disclosure of the other customer’s confidential information to Client. If another customer wishes to conduct an audit that relates to the Services for purposes of confirming that the other customer’s Intellectual Property is adequately protected, then Client shall discuss whether to waive Provider’s confidentiality obligations to Client to the extent necessary to allow the other customer to conduct the audit in a manner that does not involve disclosure of Client’s Confidential Information to the other customer. Such audits may involve an independent auditor designated by Provider and paid for by the person seeking the audit.

| 11.4 | Termination for Legal Reason. If any applicable law (including any Applicable Law), rule, regulation, guideline, or order in effect and as amended from time-to-time or any potential change in or new applicable law, rule, regulation, guideline, or order (any such law, rule, regulation, guideline, or order, new or existing, or any change or potential change to any of the foregoing, an “Interfering Law”) would or could reasonably be expected to have a Material Adverse Effect, then Client will have the right to terminate this Agreement and any and all Work Orders immediately by providing written notice to Provider describing the Interfering Law and the Material Adverse Effect such Interfering Law would or could reasonably be expected to have and explaining why such Interfering Law has caused Client to need to terminate this Agreement or any Work Order in order to avoid or mitigate such Material Adverse Effect. No Cancellation Charge(s) under Section 12 will be applied for termination of the Agreement or an applicable Work Order under this Section 11.4.

| 11.5 | Technology Transfer. Without limiting any of Client’s technology transfer rights or Provider’s technology transfer obligations under that certain Amended & Restated Cell Line License Agreement between Client and Provider dated February 3, 2025: upon Client’s prior written request and with at least [***] notice to Provider (whether during the Term of this Agreement or upon termination of this Agreement or any Work Order), Provider shall use [***] to disclose, make available, and conduct a full transfer, and shall cause its Affiliates to disclose, make available, and conduct a full transfer to Client, its Affiliates, or any third party designated by Client, all materials and information, including Provider IP (in each case, owned or controlled by Provider or any of its Affiliates) (a) with respect to tangible materials, as reasonably requested by Client and (b) that are necessary or reasonably useful for Client and such Affiliates and third parties to manufacture and otherwise exploit the Product (“Technology Transfer”). The Parties shall [***] agree to a schedule and plan for such Technology Transfer and will use [***] to conduct and complete the Technology Transfer in accordance with such plan and schedule. Provider will provide reasonable assistance to enable Client, its Affiliates, or such third party manufacturer to manufacture Product, provided, however, it is the third party manufacturer’s full responsibility to manufacture such Client Product after the transfer; Provider will not be responsible for the third party manufacturer’s success or failure to manufacture any Products. Initiation of such technology transfer will be determined by Client. For clarity, upon Client’s request, the Parties shall work [***] to develop and execute a separate agreement that specifies the Technology Transfer activities, schedule, and compensation owed to Provider (a “Technology Transfer Agreement”). Provider will also provide reasonably requested ongoing technical support and assistance if requested by

Client with such support reimbursed on a [***] rate basis. The electronic portion of any Technology Transfer (i.e., the transfer of intangible intellectual property, documents, records, etc. necessary to effectively transfer the Manufacturing Process) requested due to termination of this Agreement due to an Interfering Law pursuant to Section 11.4: (x) will be provided by Provider [***] to Client and (y) will include [***] non-chargeable hours of Provider consultation to Client, valid [***] from the date of signature of the Technology Transfer Agreement; provided that, regardless of the reason that the Technology Transfer is requested, Client shall be responsible for all reasonable and documented third-party shipping costs associated with shipment of any tangible materials (e.g., cell banks, reference standards, etc.). For clarity, Provider will complete any additional consultation or other “non-electronic” work required to effect the subject Technology Transfer at rates agreed [***] by the Parties.

| 11.6 | Survival. Upon termination of this Agreement or a Work Order, all outstanding rights and obligations between the Parties arising out of or in connection with this Agreement or the Work Order, as the case may be, will [***] terminate, other than any obligations that (a) matured prior to the effective date of the termination or (b) by its nature are intended to survive, including Sections 2.1, 4.2, 4.3, 4.6, 6.1, 6.2, 11.4, 11.5 and Articles 1, 7-10, 12 and 14. Provider will, upon receipt of a termination notice from Client, [***] cease performance of the applicable Services and will take all reasonable steps to mitigate the out-of-pocket expenses incurred in connection therewith. Within [***] after the close-out of a Work Order, Provider will provide to Client a written itemized statement of all work performed by it in connection with the terminated Work Order, an itemized breakdown of the payments associated with that work, and a final invoice for that Work Order. If Client has pre-paid to Provider more than the amount in a final invoice then Provider agrees to [***] refund that money to Client, or to credit the excess payment toward another existing or future Work Order, at the election of Client.

| 11.7 | Termination Fee.

If a Work Order is terminated early by Client under Section 11.2 or 11.3, then Client shall pay Provider for the Services rendered in accordance with the terms of this Agreement and all non-cancelable obligations in connection with the Services to the extent specified in the applicable Work Order; provided that Provider will use [***] to mitigate such non-cancellable obligations.

| (a) | If non-manufacturing Services, as specified in the applicable Work Order, are terminated by Provider due to Client’s material breach pursuant to Section 11.3(b), then Provider may charge Client a termination fee equal to [***] of the

If Client requests to 1) postpone or reschedule, or 2) materially change the production scale or batch size of, a manufacturing run originally scheduled under an executed Work Order or Change Order and/or this Agreement, the same cancellation terms in Section 12 will apply, provided that no cancellation fees will be charged in where such termination results from Provider’s breach of this Agreement, or its negligence or willful misconduct.
