(b) In the event that (i) the conditions set forth under Section 1.01(a) (ii)(B)(1) or (2) are satisfied and (ii) a final, binding and non-appealable order has been entered by a bankruptcy court finding that RemainCo has no indemnity obligations to any Corteva Third Party Beneficiary under the 2019 SDA in respect of DWDP Legacy Liabilities (and for the avoidance of doubt, none of the Corteva Third Party Beneficiaries is hereby waiving any of its rights in respect of any such bankruptcy proceeding), then (A) notwithstanding anything to the contrary in the 2025 SDA or the Partial Assignment Agreement, as between any Corteva Third Party Beneficiary and ElectronicsCo, the DWDP Legacy Liabilities shall be managed by Corteva pursuant to the provisions of this Section 1.01(b) and Article VII of the 2025 SDA shall not apply in any respect except for Section 7.01 of the 2025 SDA and (B) Corteva shall become the Managing Party (as defined in the 2019 SDA) under Article VII of the 2019 SDA with respect to such DWDP Legacy Liabilities and, notwithstanding anything to the contrary in the 2019 SDA, shall have the right to appoint all members of the Shared Historical DuPont Claim Committee (as defined in the 2019 SDA) and may assume and control the defense of any Third Party Claim related to, arising out of or resulting from the relevant DWDP Legacy Liability that gives rise to the Relevant ElectronicsCo Indemnity/Payment Obligations (each a “Relevant Legacy Liability”) (including exclusive authority to manage, control, conduct or defend (or assume the defense of) or otherwise determine all matters whatsoever (including, as applicable, litigation strategy and choice of legal counsel or other professionals and any amendment, modification or supplement to any Contract related to Relevant Legacy Liabilities that includes parties other than the Parties (and their respective Affiliates) as party to such Contract (but, without the express written consent of ElectronicsCo, not any portion thereof that, (w) under the terms of such Contract, is binding only as between the Parties and/or their respective Affiliates, (x) imposes liability on ElectronicsCo (or its Affiliates) for a share of the Relevant Legacy Liability that is greater than the Applicable ElectronicsCo Percentage of such Relevant Legacy Liability, (y) amends, modifies or supplements this Agreement or any Corteva Third Party Beneficiary Right or (z)

would impose any joint or several direct liability on ElectronicsCo (and/or its Affiliates) with respect to any Relevant Legacy Liability or other Liability where no such joint or several direct liability already exists (as opposed to liability pursuant to ElectronicsCo’s indemnification obligations under this Agreement and the 2025 SDA), and for the avoidance of doubt, excluding any amendment, modification or supplement to the allocation of, including the Specialty Products Shared Historical DuPont Percentage and Agriculture Shared Historical DuPont Percentage (each as defined in the 2019 SDA) of, any applicable DWDP Legacy Liabilities under the 2019 SDA, the 2019 Letter Agreement or the MOU)) on behalf of ElectronicsCo in respect of the Relevant Legacy Liability); provided, however, that Corteva shall not be entitled to assume the defense of any such Third Party Claim to the extent such Third Party Claim (x) is an allegation of a criminal violation by ElectronicsCo, (y) seeks injunctive, equitable or other relief other than monetary damages against ElectronicsCo (provided that ElectronicsCo shall reasonably cooperate with Corteva, at the request of Corteva, in seeking to separate any such claims from any related claim for monetary damages if this clause (y) is the sole reason that such Third Party Claim is a Non-Assumable Third Party Claim) or (z) is made by a Governmental Entity against ElectronicsCo (clauses (x), (y) and (z), the “Non-Assumable Third Party Claims”). ElectronicsCo shall have the right to employ separate counsel and to participate in (but not control) the defense, compromise or settlement thereof, at its own expense and, in any event, shall cooperate with Corteva in such defense and omit from taking any action that would be reasonably likely to interfere with or adversely affect the rights and powers of Corteva to so manage and control such defense and make available to Corteva and its representatives all witnesses, employees, officers, directors, agents, properties, pertinent information and materials in ElectronicsCo’s possession or control relating thereto as are reasonably required by Corteva and relating to the Relevant Legacy Liability, subject to appropriate restrictions for classified, privileged or confidential information; provided, however, that in the event a conflict of interest exists, or is reasonably likely to exist, that would make it inappropriate in the reasonable judgment of ElectronicsCo for the same counsel to represent both Corteva and ElectronicsCo, ElectronicsCo shall be entitled to retain separate counsel as required by the applicable rules of professional conduct with respect to such matter. With respect to the defense of a Third Party Claim as provided above, (A) Corteva shall keep ElectronicsCo apprised of all material developments in such defense, (B) Corteva shall not withdraw from the defense of such Third Party Claim without providing advance notice to ElectronicsCo reasonably sufficient to allow ElectronicsCo to prepare to assume the defense of such Third Party Claim, (C) Corteva shall conduct the defense of the Third Party Claim actively and diligently, (D) ElectronicsCo shall not admit any liability with respect to, consent to entry of any judgment of, or settle, compromise or discharge, the Third Party Claim without the prior written consent of Corteva (which consent shall not be unreasonably withheld, conditioned or delayed), (E) ElectronicsCo’s cooperation and provision of access to Corteva shall be at no additional cost or expense to Corteva (other than for actual out-of-pocket costs and expenses which shall be allocated in the same manner as the Relevant Legacy Liability), (F) any amounts owed by either Corteva or ElectronicsCo in respect of any Relevant Legacy Liability (including reimbursement for their out-of-pocket costs and expenses of defending or, in the case of ElectronicsCo, providing assistance to Corteva with respect to, any Third Party Claim that is a Relevant Legacy Liability, which shall include any out-of-pocket amounts with respect to a bond, prepayment or similar security or obligation required (or determined to be advisable by the Corteva) to be posted by Corteva in respect of any claim) shall be included in the calculation of the amount of the applicable Relevant Legacy Liability in determining the reimbursement obligations of Corteva and ElectronicsCo with respect thereto (provided that any release or refund thereof in the future shall be refunded back to

ElectronicsCo to the extent funded by ElectronicsCo), and (G) it shall not be a defense to any obligation by ElectronicsCo to pay any amounts in respect of any Relevant Legacy Liability that that ElectronicsCo does not approve of the quality or manner of the defense thereof or that such Relevant Legacy Liability was incurred by reason of a settlement rather than by a judgment or other determination of liability (even if, subject to the immediately succeeding sentence, such settlement was effected without the consent or over the objection of ElectronicsCo (unless such settlement was a Non-Assumable Third Party Claim)). Corteva shall not admit any liability with respect to, consent to entry of any judgment of, or settle, compromise or discharge, the Third Party Claim without the prior written consent of ElectronicsCo (which consent shall not be unreasonably withheld, conditioned or delayed) unless such settlement or judgment (1) completely and unconditionally releases ElectronicsCo in connection with such matter, (2) provides relief consisting solely of money damages borne by ElectronicsCo and (3) does not involve any admission by ElectronicsCo of any wrongdoing or violation of Law. Notwithstanding anything in this Section 1.01(b) to the contrary, (i) the provisions of Section 8.11(b)-(g) of the 2019 SDA shall apply mutatis mutandis to any claim related to, arising out of or resulting from the Relevant ElectronicsCo Indemnity/Payment Obligations and relating to remediation of contaminated environmental media, where the owner or primary tenant of the impacted property is not the Party (or a Subsidiary thereof) to which such liability for remediation has been allocated, and (ii) the provisions of Section 8.12 of the 2019 SDA will apply mutatis mutandis to any liabilities to the extent arising from required actions to execute demolition and removal of any buildings, improvements, facilities, equipment or other fixtures that constitute Relevant ElectronicsCo Indemnity/Payment Obligations related to the Discontinued Buildings and Related Improvements (as defined in the 2019 SDA). In the event that Corteva and ElectronicsCo disagree on whether a claim, obligation or Liability is a DWDP Legacy Liability or a Relevant Legacy Liability or whether such claim, obligation or Liability constitutes a Liability allocated to one of the Parties (or its Group) pursuant to the 2019 SDA or the 2025 SDA, as applicable, then such matter shall be resolved pursuant to and in accordance with the dispute resolution provisions set forth in Article X of the 2019 SDA.

(c) Each of ElectronicsCo and Corteva acknowledges and agrees that, in the event that the conditions set forth under Section 1.01(a)(ii)(B)(1) or (2) are satisfied, it shall be bound, in respect of any matter for which Corteva (or any other Corteva Third Party Beneficiary) or RemainCo (or a member of its Group) has sought indemnity or payment from the other for a DWDP Legacy Liability under the 2019 SDA or the 2019 Letter Agreement, by (x) the terms and conditions of any agreement in writing in respect of such matter between Corteva (or any other Corteva Third Party Beneficiary) or RemainCo (or a member of its Group) or (y) any final, binding and non-appealable arbitration award in respect of such matter issued by an Arbitral Tribunal (as defined in the 2019 SDA), pursuant to the dispute resolution provisions set forth in Article X of the 2019 SDA or the Corteva Letter Agreement, in each case of clauses (x) and (y) whether entered into or issued before, on or after the date of this Agreement, but prior to the satisfaction of the conditions set forth under Section 1.01(a)(ii)(B)(1) or (2).

Section 1.02 No Amendments of Corteva Third Party Beneficiary Rights Without Corteva Consent. Each of RemainCo and ElectronicsCo agrees that, except with the prior written consent of Corteva, it shall not waive, modify, supplement or amend (a) Section 7.1, Section 8.3 or Section 12.15(d) of the 2025 SDA or (b) Section 1(b) or Section 6 of the Partial Assignment Agreement, in each case (clauses (a) and (b)), in any manner or respect (including by waiving, modifying, supplementing or amending any other provision or schedule of the 2025 SDA, including any definitions included and used directly or indirectly in such sections) that adversely affects in any material respect the Corteva Third Party Beneficiary Rights. The Parties expressly agree that any such purported waiver, modification, supplement or amendment without Corteva’s prior written consent (if such consent is required) shall not affect in any manner or respect the rights of any Corteva Third Party Beneficiary, or the obligations of RemainCo or ElectronicsCo (or any member of their respective Groups), with respect to the Corteva Third Party Beneficiary Rights.

(a) Except as otherwise expressly set forth herein, nothing contained in this Agreement is intended to or shall be deemed to modify, alter, amend or otherwise change any of the rights or obligations of the parties and their respective Affiliates under the 2019 SDA, the 2025 SDA, the 2019 Letter Agreement and the MOU, including, for the avoidance of doubt, any allocation thereunder of liabilities among the parties thereto or any right or obligation thereunder of a party thereto or their affiliates in respect of indemnification for such liabilities. The representations, warranties, covenants, agreements and indemnities contained in the 2019 SDA, the 2025 SDA, the 2019 Letter Agreement and the MOU shall not be superseded hereby but shall remain in full force and effect to the full extent provided therein, where applicable.
