ARTICLE 1

SERVICES

Section 1.01 Provision of Services.

(a) Pursuant to the terms of this Agreement and subject to Section 1.06(b), during the Transition Period (as defined in Section 6.01), Seller shall provide or cause to be provided to Purchaser and its Affiliates the transitional services and perform the transitional activities set forth on Schedule 1 and the services set forth in Appendix C of Schedule 1 that Purchaser requests Seller provide (collectively, the “Services”).

(b) If either Party identifies any additional service that (i) is not described or included in Schedule 1, (ii) is reasonably necessary for the VOWST Business to continue to operate as conducted on the Effective Date, and (iii) was provided to the VOWST Business by Seller or its Affiliates (other than by the Transferring Employees) during the six (6) month period immediately prior to the Effective Date (an “Omitted Service”), then, at Purchaser’s request, the Parties will

amend the Services as set forth on Schedule 1 to add such Omitted Service on terms to be mutually agreed in good faith between the Parties consistent with terms of this Agreement, including the scope of Omitted Services, Services Fees (including FTE Costs, fixed non-labor costs), Out-of-Pocket Costs and related duration (which in no event will exceed the Transition Period immediately prior to the addition of such Omitted Service as a Service hereunder). The Services Fees and Out-of-Pocket Costs for any Omitted Service shall, in each case, be provided to Purchaser without profit or markup. Upon execution of such amendment, the Omitted Services shall constitute “Services” under this Agreement. Any such amendment shall be consistent with the terms of this Agreement.

(c) The Parties may, in accordance with the procedures specified in this Section 1.01: (i) agree to modify the terms and conditions relating to the performance of a previously agreed-upon Service in order to reflect, among other things, new procedures or processes for providing such Service or increased Services Fees (which in all cases shall be based on Seller’s or its Affiliates’ FTE Costs and out-of-pocket costs to provide such Services, without a markup), including but not limited to Seller’s right, from time to time, to upgrade, customize, enhance, supplement, modify, replace, substitute or otherwise change any of the Services (a “Service Modification”), or (ii) agree upon terms and conditions related to the provision of services that are in addition to any of the previously agreed-upon Services and are not Omitted Services (an “Additional Service”). Seller shall not be required to implement any Service Modification or Additional Service except as set forth in this Section 1.01.

(d) In the event either of the Parties desires a Service Modification or an Additional Service (in each case, a “Change”), the Party requesting the Change will deliver a written description of the proposed Change (a “Change Request”) to the other Party’s Project Manager.

(e) Unless the Party receiving the Change Request agrees to implement the Change Request as proposed, the Project Managers will meet in person or by telephone to discuss and consider in good faith the Change Request no later than ten (10) Business Days after delivery of the Change Request to the other Party.

(f) Each Party’s Change Requests must be approved by both Parties in writing before the Change may be implemented in accordance with Section 1.01(d), such approval not to be unreasonably withheld, conditioned, or delayed. The Parties agree that it is not unreasonable to: (i) withhold such consent to the extent that such proposed Change would materially adversely affect Seller’s operations or business continuity or Purchaser’s receipt of the Services (including any adverse effects to either Party regarding care, quality, priority timeliness, volume, amount, scope, detail and skill) after giving effect to the Change Request, or (ii) condition such consent on Purchaser agreeing to reimburse Seller for any costs incurred by Seller to implement or accommodate such Change. In addition, notwithstanding the foregoing, Seller may, in Seller’s sole discretion, make Changes to the extent required as a result of a change in applicable Law.

(g) Subject and without prejudice to Seller’s obligations to perform the Services in accordance with Section 1.03 and Section 1.04, Seller may make changes from time to time in the manner of performing the Services if (i) performing the Services materially and adversely affects any of Seller’s other obligations and commitments (including its and its Affiliates’ business operations) or (ii) Seller can no longer provide a Service using the same resources and capabilities that Seller uses in its ordinary course of Seller’s business outside of the Services; provided, however, that, with respect to the foregoing, Seller shall provide Purchaser with reasonable advance prior written notice of any such changes promptly, and in such case shall discuss such changes in good faith with Purchaser and shall work together with Purchaser to devise and perform a mutually acceptable alternative arrangement for the provision of the impacted Service and provided that any increase in costs of providing the Services as a result of the change shall be for the sole account of Seller.

(h) Notwithstanding anything to the contrary herein, neither Seller nor any of its Affiliates will be required to perform or to cause to be performed any Service (a) for the benefit of any Person other than Purchaser, its Affiliates, its sublicensees or its suppliers or service providers; or (b) that exceed the scope of the services provided by Seller or its Affiliates to the Acquired Assets immediately prior to the Effective Date, unless otherwise agreed in writing by the Parties.

(i) Each Party represents that it has obtained and will maintain, and has caused and will cause each of its affiliates, subcontractors and licensees (including Seller Affiliate and Subcontractor), if applicable, to obtain and maintain, in full force and effect all licenses, registrations, and permits required to perform its obligations under this Agreement. Each Party shall inform the other Party within [***] should any such license, registration or permit be withdrawn or if any regulatory authority initiates any enforcement action against a Party or any of its affiliates, subcontractors or licensees with respect to any obligation to perform hereunder.

Section 1.02 Duration of Services. During the Transition Period (as defined in Section 6.01), and in consideration of Purchaser’s payment of Services Fees in accordance with Article 2, Seller shall provide or cause to be provided to Purchaser, subject to the terms and conditions of this Agreement, each Service for the time period associated with such Service set forth on Schedule 1 (each, a “Service Period”).

Section 1.03 Services Performed by Affiliates and Subcontractors. Seller shall have the right, but not the obligation, to perform any Service itself or through any Affiliate of Seller or through any Subcontractor that Seller engaged to provide such Service in the course of Seller’s operation of the VOWST Business or facility immediately prior to the Effective Date; provided, however, that (a) designation of any such Affiliate or Subcontractor shall not limit or diminish the obligations of Seller, and Seller shall in all cases retain responsibility for the provision to Purchaser of the Services in accordance with this Agreement, (b) the use of any Affiliate or Subcontractor shall not increase any fees or other amounts payable by Purchaser (or its Affiliate) (as compared to the amount of fees or other amounts payable for use of such Affiliate or Subcontractor immediately prior to the Effective Date) except to the extent there is an increase in the actual Services Fees and Out-of-Pocket Costs incurred by Seller in the provision of such Services, without a markup, and (c) Seller shall provide reasonable prior written notice to Purchaser of such designation.

Section 1.04 Performance Standard.

(a) Seller shall provide, and cause its Personnel to provide, each Service in a professional and workmanlike manner and in accordance with all Specifications set forth in the BLA and other Acquired Regulatory Approvals, to the extent applicable to a Service, using knowledgeable, skilled and qualified Personnel who have not been disbarred or otherwise sanctioned by a Regulatory Authority, with substantially the same degree of skill, quality, volume, scope, detail and care as its past practice in performing or causing to be performed the Services for the VOWST Business during the six (6) month period prior to the Effective Date (except to the extent changes in the provision of Services are necessary due to Purchaser’s acts or omissions), in each case, in accordance with industry standards, applicable guidelines and processes (but in all cases with at least reasonable care and at least in the manner and at the levels that Seller provides, or causes to be provided, similar services for itself and its Affiliates), and, solely in the case of the PRMS Services performed by Seller (which, for the avoidance of doubt, shall not include any Services performed by any Transferring Employee that is no longer an employee of Seller as of the Effective Date, regardless of whether such Transferring Employee use Seller’s payroll system after the Effective Date), in accordance with the PRMS Services Quality Standards set forth in the Quality Agreement (collectively, the “Services Standard”), except as such Services differ because of the need to follow corporate formalities or to keep Acquired Assets separate from other data or by virtue of the transition of responsibility for the Services to Purchaser or its Affiliates. Notwithstanding the foregoing, nothing in this Agreement shall require Seller to favor Purchaser’s operation of the Acquired Assets over Seller’s own business operation.

(b) Under no circumstances shall either Party or its respective Representatives, Personnel, Affiliates or Subcontractors be held accountable to a greater standard of care or skill than the Services Standard. EXCEPT AS OTHERWISE EXPRESSLY PROVIDED IN THIS AGREEMENT, TO THE EXTENT PERMITTED BY LAW, EACH SERVICE PROVIDED BY SELLER TO PURCHASER PURSUANT TO THIS AGREEMENT IS FURNISHED WITHOUT CONDITION, WARRANTY OR OTHER TERM OF ANY KIND, EXPRESSED OR IMPLIED. NEITHER PARTY NOR ANY OF ITS AFFILIATES MAKES ANY REPRESENTATION, EXPRESS OR IMPLIED, WITH RESPECT TO SUCH SERVICE AND ALL IMPLIED TERMS, WHETHER IMPLIED BY CUSTOM, STATUTE, COURSE OF DEALING OR OTHERWISE (INCLUDING ANY TERM OF MERCHANTABILITY, SATISFACTORY QUALITY, NON-INFRINGEMENT OR FITNESS FOR A PARTICULAR PURPOSE) ARE HEREBY EXCLUDED, IN EACH CASE, EXCEPT AS OTHERWISE SPECIFICALLY CONTEMPLATED BY THIS AGREEMENT.

Section 1.05 Transition Management; Disputes.

(a) General. Purchaser acknowledges and agrees that each Service provided by Seller hereunder is intended only to be transitional in nature and shall be furnished by Seller only during the Transition Period and solely in connection with the sale and transfer of Acquired Assets under the Purchase Agreement.

(b) Transition Management. The Parties shall establish a transition steering committee (the “TSA Steering Committee”), consisting of a mutually agreed upon number of representatives of each Party. The Parties agree that, at all times during the Transition Period, the TSA Steering Committee shall serve as transition management with respect to all questions and issues relating to the provision and receipt of the Services. Each Party shall appoint one (1) of its representatives on the TSA Steering Committee as a project manager (a “Project Manager”). Each Party’s Project Manager shall have responsibility for overseeing such Party’s day-to-day activities under this Agreement and will be authorized to act for and on behalf of the appointing Party concerning all matters relating to this Agreement. Each Party may change its designated Project Manager at any time by providing notice to the other Party. All Project Managers shall have the requisite skills, knowledge, experience and authority to discuss, coordinate and make arrangements with respect to the applicable Services. The TSA Steering Committee shall meet in-person, telephonically or by videoconference once per month during the Transition Period, or as otherwise mutually agreed by the Parties. Attendance of each Party’s Project Manager at each such meeting is required. The Project Managers shall meet telephonically on a weekly basis in between the TSA Steering Committee meetings. The Parties shall host meetings for each Service function either in-person, telephonically or by videoconference at least twice per month during the Transition Period. Such meetings shall be attended by respective representatives of each Party for each Service function. In furtherance of the foregoing, the Parties shall collaborate in good faith to generate a detailed plan for (x) the transition of the Acquired Assets in accordance with any applicable terms of this Agreement, the Purchase Agreement and the Cross-License Agreement and (y) the transition of the Services from Seller to Purchaser. If the TSA Steering Committee is unable to reach unanimous decision on a particular matter within a reasonable period (not to exceed thirty (30) days, unless extended by mutual agreement of the Parties) following the TSA Steering Committee meeting, then the matter will be referred to, as appropriate, Seller’s Chief Executive Officer, Chief Financial Officer, Chief Technology Officer, or other senior officers and ▇▇▇▇▇▇▇▇▇’s Chief Executive Officer, Chief Operations Officer/Chief Technology Officer, Chief Medical Officer, or other senior officers, depending on the subject matter of the dispute (the “Senior Officers”), which Senior Officers will have authority to settle the dispute and shall be charged with resolving such dispute, who will use good faith efforts to resolve such matter after the matter is submitted to them for resolution in accordance with Section 1.05(c).

(c) Prior to initiating any legal action in accordance with Section 8.06, any dispute, controversy or claim arising out of, relating to or otherwise in connection with the Services or this Agreement, or the breach, termination, or validity thereof (each, a “Dispute”), shall be submitted first to the relevant Senior Officers of each Party, and the Senior Officers shall seek to resolve such Dispute through informal, good-faith negotiation. In the event that any Dispute is not resolved by the Senior Officers within twenty (20) Business Days after the claiming Party notifies the other Party of the Dispute (during which time the Senior Officers shall meet in person or by telephone as often as reasonably necessary to attempt to resolve the Dispute), either Party may bring an action in accordance with Section 8.06 to resolve the Dispute.

Section 1.06 Cooperation. Each Party will use commercially reasonable efforts to cooperate in a professional and workmanlike manner with the other Party to the extent necessary to assist the other Party in performance of its obligations under this Agreement, including with respect to the provision and receipt of Services. Such cooperation shall include exchanging or providing information, Raw Materials, and SRM reasonably necessary for the provision or receipt of Services hereunder and the performance of such other duties and tasks as may be reasonably required for the provision or receipt of Services, subject to each Party’s obligations herein including Article 4. Each Party shall, and shall cause its Personnel and Affiliates to, comply, in all material respects, with all Laws which may be applicable to the Services. Each Party shall be responsible for its Personnel adhering to any health, safety and security regulations and other published policies of the other Party notified to such Party when given access to any equipment, computer, software, network or other files owned or controlled by the other Party. Without limiting the generality of the foregoing sentence:

(a) Each Party agrees that, subject to applicable Law, it shall provide such reasonable access during regular business hours (or otherwise upon reasonable prior notice) to such premises, computer systems, data, Raw Materials, SRM and Personnel as are necessary for providing or receiving the Services, and records as reasonably requested by a Party to facilitate such Party’s provision or receipt of the Services. Unless otherwise agreed to in writing by the Parties, each Party will: (i) use the premises, computer systems, data, Raw Materials, SRM and Personnel of the other Party solely for the purpose of providing or receiving the Services; (ii) limit such access to those of its Personnel with a bona fide need to have such access in connection with the Services and who have been duly approved in writing by the receiving Party, such approval not to be unreasonably withheld, conditioned or delayed, to have such access: and (iii) comply, and cause its employees, Subcontractors and Third Party service providers to comply, with all policies and procedures governing access to and use of such premises, computer systems, data, Raw Materials, SRM and Personnel made known to such Party in advance. All user identification numbers and passwords disclosed by a Party to the other Party and any information obtained by either Party as a result of such Party’s access to and use of the other Party’s computer systems shall be deemed to be, and treated as, Confidential Information of the disclosing Party hereunder in accordance with the provisions set forth in Article 4, with the same degree of care as such receiving Party uses for its own information of a similar nature, but in no event a lower standard than a reasonable standard of care. The Parties shall cooperate in good faith in the investigation of any apparent unauthorized access to any premises, computer system, data, Raw Materials, SRM and/or Personnel of either Party. These provisions concerning access to premises, computer systems, data, Raw Materials, SRM or Personnel shall apply equally to any access and use by a Party of the other Party’s electronic mail system, electronic switched network, either directly or via a direct inward service access or calling card feature, data network or any other property, equipment or service of the other Party, and any software that may be accessible by either Party in connection with this Agreement.

(b) Seller shall be excused from performing any obligation under this Agreement, nor shall Purchaser be excused from making Installment Payments in accordance with Section 3.1(b) of the Purchase Agreement, if Purchaser fails to perform its obligations under this Agreement, including but not limited to Purchaser’s failure to provide cooperation as set forth in this Section 1.06, a failure by Purchaser to deliver to Seller all SRM that is reasonably necessary by Seller to manufacture PRMS for the PRMS Services, and a failure by Purchaser to perform quality control testing of PRMS in order to support the release of PRMS for drug substance manufacturing,

in each case, solely (i) to the extent such failure to perform by Purchaser was not caused by Seller’s material breach of or failure to perform its obligations under this Agreement, (ii) to the extent that such failure prevents Seller’s performance of such obligation after using commercially reasonable efforts to perform and (iii) until such time as such failure to perform by Purchaser has been remedied or cured. Seller shall notify Purchaser within ten (10) Business Days of its discovery of such failure. Where Purchaser fails to perform its obligations under this Agreement, and if as a result of such failure Seller incurs additional costs in order to perform its obligations hereunder, Seller may recover from Purchaser its reasonable and documented additional costs of performing the relevant obligations hereunder incurred as a result of Purchaser’s failure.

(c) Concurrently with the execution of this Agreement, the Parties shall amend and restate the Quality Agreement to reflect the PRMS Services being provided.

Section 1.07 Third Party Consents.Section 1.07

(a) Seller shall use its commercially reasonable efforts to obtain any Contract, license (including any modification to, extension or renewal of, or replacement for an existing license), or consent or waiver under its own Contracts entered into with any Third Party and that pertain to any software, equipment, systems or other materials or associated services required in connection with performance or receipt of the Services under this Agreement (each, a “Required Consent”); provided, that if, in order to obtain any Required Consent, costs or expenses must be incurred, the costs and expenses incurred to obtain Required Consents required by Seller in connection with its performance of the Services shall be solely borne by Purchaser and constitute Allowable Expenses under the Purchase Agreement. Purchaser shall use its commercially reasonable efforts to cooperate with the Seller in obtaining such Required Consents from Third Parties.

(b) If, despite using commercially reasonable efforts, Seller is unable to obtain a Required Consent hereunder, Purchaser and Seller shall work together in good faith to develop a mutually acceptable alternative arrangement that is sufficient to enable Seller to provide, and Purchaser to receive, the Services without such Required Consent. Purchaser shall bear the costs and expenses of such alternative arrangement incurred by either Party, as applicable, which costs and expenses shall constitute Allowable Expenses under the Purchase Agreement to the extent the costs of the Service to which such alternative arrangement relates are included in Allowable Expenses pursuant to the Purchase Agreement. If such alternative arrangement cannot be agreed upon by Purchaser and Seller or is required for a period longer than thirty (30) days following the Effective Date, either Party may request that the affected Services be terminated, in which case the Services Fees and Out-of-Pocket Costs for such Services, if any, shall be equitably adjusted to account for such terminated Services, reflecting the actual FTE Costs and Out-of-Pocket Costs incurred by Seller. Seller shall have no obligation (and no Liability for failing) to provide (or cause the provision of) a Service for which a Required Consent has not been obtained, unless and until such Required Consent is obtained, so long as Seller has complied with this Section 1.07.

(c) Purchaser acknowledges and agrees that any Services provided through or involving Third Parties or using any Intellectual Property owned by a Third Party or systems or facilities are subject to the terms and conditions of any applicable Contracts between Seller or its Affiliates or Subcontractors (as applicable) and such Third Parties, as well as compliance with applicable Law. Purchaser shall comply, and shall cause its Affiliates to comply, with the terms and conditions of any such applicable Contracts notified to Purchaser from time to time in all material respects, and with applicable Law in connection with the receipt by Purchaser or its designees of the Services, provided that Seller shall, and shall use commercially reasonable efforts to, and cause its Affiliates and Subcontractors to, provide Purchaser reasonable information in advance with respect to such terms and conditions, subject to any confidentiality obligations under the applicable Contract.

Other than in the case of Purchaser’s election of clause (i) in the immediately preceding sentence, the Additional PRMS Batches shall be provided at the same per-batch cost as set forth in the Demand Plan for the Minimum Requirement.

If at the end of the Service Period for the PRMS Services, the aggregate PRMS amount for all Firm Orders is less than the Minimum Requirement, then Seller shall invoice Purchaser for an amount equal to the difference in quantity between the Minimum Requirement and the aggregate amount of PRMS included in confirmed Firm Orders multiplied by the variable cost per batch stipulated on Schedule 1. Any such amounts so invoiced by Seller shall be paid by Purchaser in accordance with Section 2.04 and Section 2.05.

(f) If Purchaser requests the production of any PRMS batches that are not included in the Minimum Requirement and Additional PRMS Batches, the Parties will discuss in good faith the terms of the production of any such PRMS batches, including the costs of such PRMS batches and delivery timeline.

Such costs and expenses related to the PRMS Technology Transfer Plan for the PRMS Services shall constitute Allowable Expenses under the Purchase Agreement.

The Parties agree to reasonably cooperate to apply for any exemption from, or reduction in, any withholding amounts described in this Section 2.07(b).

(c) Cooperation. Seller and Purchaser shall take reasonable steps to cooperate to minimize the imposition of, and the amount of, taxes described in this Section 2.07, provided that nothing in this Section 2.07(c) will obligate a Party to cooperate with, or assist, the other Party in any arrangement proposed by the other Party that would, in the cooperating Party’s reasonable discretion, have a detrimental effect on the cooperating Party or any of its Affiliates with respect to taxes.

(a) If a claim for indemnification pursuant to Section 5.01 or Section 5.02 (a “Claim”) is to be made by an Indemnified Party entitled to indemnification hereunder, the Indemnified Party claiming indemnification shall give written notice to the other Party (the “Indemnifying Party”) reasonably promptly after the Indemnified Party becomes aware of any fact, condition or event that may give rise to Damages for which indemnification may be sought under Section 5.01 or Section 5.02, or receipt by the Indemnified Party of notice of a claim involving the assertion of a claim by a Third Party that may give rise to Damages for which indemnification may be sought under Section 5.01 or Section 5.02 (whether pursuant to a lawsuit, other legal action or otherwise, a “Third Party Claim”). The failure of any Indemnified Party to give timely notice hereunder shall not affect its rights to indemnification hereunder, except to the extent that the Indemnifying Party is actually prejudiced by such failure. The Indemnifying Party shall have thirty (30) days (or such lesser number of days set forth in the notice as may be required by court proceeding in the event of a litigated matter) after receipt of the notice to notify the Indemnified Party that it desires to defend the Indemnified Party against such Third Party Claim. Notwithstanding the foregoing, if such Third Party Claim (i) seeks injunctive, equitable or other relief or remedies that are not money damages against the Indemnified Party, or (ii) involves criminal allegations against the Indemnified Party, then the Indemnified Party shall have the right to control the defense, compromise or settlement of such Third Party Claim with counsel of its choice (and the costs thereof, for the avoidance of doubt, shall constitute Damages for which indemnification may be sought under Section 5.01 or Section 5.02).

(b) If the Indemnifying Party assumes the defense, compromise or settlement of such Third Party Claim, the Indemnified Party shall make available to the Indemnifying Party any documents and materials in its or its Affiliates’ possession or control that may be necessary to the defense of such Third Party Claim (provided that the Indemnified Party shall not be required to furnish any such documents or materials which would (in the reasonable judgment of such party upon advice of counsel) be reasonably likely to (i) constitute a waiver of the attorney-client or other privilege held by such party or any of its Affiliates, (ii) violate any applicable Laws or (iii) breach any agreement of such party or any of its Affiliates with any Third Party; provided that such Indemnified Party shall use reasonable best efforts to obtain any required consents and take such other reasonable action (such as the entry into a joint defense agreement or other arrangement to avoid loss of attorney-client privilege) to permit such disclosure) and the Indemnifying Party shall keep the Indemnified Party reasonably informed of all material developments and events relating to such Third Party Claim. The Indemnified Party, at its sole option, may participate in any defense and investigation of such Third Party Claim or settlement negotiations with respect to such Third Party Claim. The fees and disbursements of counsel retained by such Indemnified Party shall be at the expense of the Indemnified Party, provided, that if in the reasonable opinion of counsel to the Indemnified Party, there are legal defenses available to the Indemnified Party that are different from or additional to those available to the Indemnifying Party, or there exists a conflict of interest between the Indemnifying Party and the Indemnified Party that cannot be waived, the Indemnifying Party shall be liable for the reasonable fees and expenses of counsel to such Indemnified Party in each jurisdiction for which the Indemnified Party determines counsel is required (and the costs thereof, for the avoidance of doubt, shall constitute Damages for which indemnification may be sought under Section 5.01 or Section 5.02). Except with the written consent of the other Party (not to be unreasonably withheld, conditioned or delayed), neither the Indemnifying Party nor the Indemnified Party shall, in the defense of a Third Party Claim, consent to the entry of any judgment or enter into any compromise or settlement (A) which does not include as an unconditional term thereof the giving to the other Party and its Affiliates by the Third Party of a release from all liability with respect to such suit, claim, action or proceeding, (B) if such judgment, compromise or settlement involves a finding or admission of (x) any violation of Law by the other Party (or any Affiliate thereof) or (y) any liability on the part of the Indemnified Party (or any Affiliate thereof) not indemnified hereunder, or (C) which involves injunctive, equitable or other relief or remedies that are not money damages against the other Party. With respect to Claims other than Third Party Claims, after the giving of any notice of a Claim pursuant to this Section 5.03, the amount of indemnification to which an Indemnified Party shall be entitled under this Article 5 shall be determined (1) by the written agreement between the Indemnified Party and the Indemnifying Party, (2) in accordance with Section 8.05 or (3) by any other means to which the Indemnified Party and the Indemnifying Party shall agree.

Section 5.04 Limitations on Liability.

(a) Neither Party nor any of its respective Affiliates shall be liable to the other Party or any of its Affiliates for any consequential, special, incidental or indirect damages, lost profits, diminution in value, exemplary or punitive damages arising from or in connection with providing or failing to provide a Service, whether such claim is based on contract, tort or warranty (including negligence or strict liability) or otherwise, even if an authorized Representative of such Party is advised of the possibility or likelihood of the same, provided that, for clarity, any such damages arising from or in connection with the indemnification obligations set forth in Section 5.01 or Section 5.02 with respect to Third Party Claims shall be considered direct damages.

(b) Except for any damages arising from or in connection with Seller’s reckless or willful misconduct or fraud or breach of Article 4 (Confidentiality), including Exhibit B, the maximum amount for which Seller shall be liable for claims made by Purchaser for Damages with respect to this Agreement (including under Section 5.02), the Services or the transactions contemplated by this Agreement shall not exceed the aggregate amount of Services Fees paid prior to such claim by Purchaser to Seller hereunder (the “Cap”).

Thereafter, the Parties will negotiate in good faith the terms of the requested Service Period extension. For the avoidance of doubt, no Service will be extended without the mutual consent of the Parties, such consent not to be unreasonably withheld, conditioned or delayed.

(c) With respect to the PRMS Services, upon notice from Purchaser to Seller no later than June 30, 2025, Purchaser shall have the right to extend the Service Period for the PRMS Services for up to six (6) additional months solely to ensure the facility that is manufacturing PRMS is in a state of compliance with the BLA for the Vowst Product and readiness for potential regulatory inspection; provided that if any other Service is interdependent with the PRMS Services, Purchaser must also extend such interdependent Services, to the extent necessary pursuant to Section 6.02(c).

Section 6.04 Effect of Termination or Reduction in Scope or Volume. Upon termination or reduction in scope or volume of any Service pursuant to this Agreement:

(a) In the case of a termination by Purchaser pursuant to Section 6.02(a) or by Seller pursuant to Section 6.02(b) or Section 6.02(d), Purchaser shall pay (or cause its Affiliate to pay) to Seller (or any Affiliate designated by it) all applicable Early Termination Charges, which shall be invoiced and paid as provided in Section 2.03, Section 2.04, Section 2.05 and Section 2.08. “Early Termination Charges” means any and all non-cancelable or incremental and documented out-of-pocket fees or expenses actually incurred and payable to any Subcontractor as a result of any early termination or reduction in scope or volume of a Service (which fees and expenses may include breakage fees, or early termination fees or charges);

Seller shall use, implement, and maintain commercially reasonable safeguards to protect Purchaser’s Personal Information, including those required by Applicable Data Protection Laws.
