The Dow Chemical Company Executives' Supplemental Retirement Plan Supplemental Benefits, restated and effective as of January 1, 2024

On May 14, 1992, The Dow Chemical Company established The Dow Chemical Company Executives’ Supplemental Retirement Plan (the “Executives’ Supplemental Retirement Plan”) as an unfunded program of deferred compensation, which included Part A for non-U.S. service, non-controlled group service and/or non-covered controlled group service and Part B for employees whose benefits under the Dow Employees’ Pension Plan (the “DEPP”) are limited by sections 401(a)(17) and 415 of the Internal Revenue Code of 1986, as amended (the “Code”). The Executives’ Supplemental Retirement Plan was amended and restated several times after its establishment, including to comply with the requirements of Code section 409A with respect to those amounts that are not grandfathered under Code section 409A. (The portion of the Executives’ Supplemental Retirement Plan consisting of amounts that were “earned and vested,” within the meaning of Code section 409A, prior to 2005 and are therefore exempt from the requirements of Code section 409A (“Grandfathered Amounts”) can be found in Appendix A of the document in effect on and before the Closing Date described below.)

In connection with the change of control resulting from the transaction described in the Agreement and Plan of Merger (as defined in Article I), certain benefits accrued through the closing date of the transaction (the “Closing Date”) were paid to participants in a single lump sum pursuant to section 4.01(b)(v) of the Executives’ Supplemental Retirement Plan. Effective as of the day after the Closing Date, Part A of the Executives’ Supplemental Retirement Plan was spun off to form The Dow Chemical Company Executives’ Supplemental Retirement Plan — Restricted and Cadre Benefits. Part B of the Plan, renamed “The Dow Chemical Company Executives’ Supplemental Retirement Plan — Supplemental Benefits,” is amended as set forth in this restatement, effective as of the day after the Closing Date.

The purpose of The Dow Chemical Company Executives’ Supplemental Retirement Plan — Supplemental Benefits (the “Plan”) is to provide certain management and highly compensated employees of The Dow Chemical Company and certain affiliated entities with retirement benefits that would otherwise be provided by the DEPP, but for the limitations imposed by Code sections 401(a)(17) and 415, and that are not otherwise provided by any other plan maintained by The Dow Chemical Company or those affiliated entities.

The changes made by this 2024 Restatement apply to all amounts deferred under the Plan, except:

•to the extent otherwise indicated;

•to the extent that any change would result in a “material modification” (within the meaning of the regulations under Code section 409A) of a Grandfathered Amount; or

•that the vested accrued benefit of a Participant whose annuity starting date occurred on or before the Closing Date shall be the amount, as reflected in the Plan Administrator’s records, determined pursuant to the terms of the Executives’ Supplemental Retirement Plan in effect on the date of the Participant’s retirement, death or other termination of employment, unless otherwise provided in a subsequent amendment or restatement.

The Plan is intended to (a) constitute an unfunded program maintained primarily for the purpose of providing deferred compensation for a select group of management or highly compensated employees consistent with the requirements of ERISA sections 201(2), 301(a)(3), and 401(a)(1), and (b) comply with Code section 409A and official guidance issued thereunder. Notwithstanding any other provision of the Plan, the Plan shall be interpreted, operated, and administered in a manner consistent with these intentions.

Effective January 1, 2024, no Participant shall accrue any additional benefits under the Plan on or after January 1, 2024; no individual who was not a Participant in the Plan as of December 31, 2023, shall become a Participant; and any individual who is or was a Participant in the Plan who is rehired on or after January 1, 2024, shall not resume active participation in the Plan and shall not accrue any additional benefits under the Plan during such period of reemployment.

a.In general. The amount of a Participant’s DEPP Component Supplemental Retirement Benefit equals:

i.the amount that would be payable to or on behalf of the Participant under the DEPP Component if the provisions of the DEPP providing for the limitation of benefits in accordance with Code sections 401(a)(17) and 415 were inapplicable

minus:

ii.the sum of (A) the benefit payable to or on behalf of the Participant under the DEPP, (B) the benefit paid to the Participant from the Plan in connection with the change of control resulting from the Orion Merger, and (C) any other benefit paid to the Participant under the Plan.

b.Vesting. A Participant’s vested interest in the Participant’s DEPP Component Supplemental Retirement Benefit calculated under this Section 3.1 (i.e., vesting percentage) shall be determined in accordance with the applicable vesting terms contained in the DEPP.

c.Cessation of Accruals. No Participant shall accrue additional benefits on or after January 1, 2024. For each Participant who is actively participating and accruing a DEPP Component Supplemental Retirement Benefit as of December 31, 2023, a notional account balance shall be established based on such Participant’s DEPP Component Supplemental Retirement Benefit, determined in accordance with Section 3.1(a), and such notional account balance shall accrue interest, at the same rate applicable to account balances under the DEPP Component, beginning on January 1, 2024, and through the Participant’s benefit commencement date (or the Participant’s Lump Sum Determination Date, if the Participant elects to receive a Lump Sum Distribution in accordance with Section 4.3).

a.Amount. The amount of PPA Component Supplemental Retirement Benefits payable to a Participant equals the benefit which would be payable to or on behalf of the Participant under the PPA Component of the DEPP if Compensation as defined in Section 1.10 were substituted for compensation as defined in the DEPP and the provisions of the DEPP providing for the limitation of benefits in accordance with Code sections 415 and 401(a)(17) were inapplicable, less the benefit actually payable to or on behalf of the Participant under the DEPP.

b.Effect of Orion Merger. With respect to Participants who received a single lump-sum payment in connection with the change of control resulting from the Orion Merger, the amount of PPA Component Supplemental Retirement Benefits shall be calculated under the formula set forth in Section 3.2(a) using only Pay Credits and Interest Credits that have accrued after such change of control.

c.Vesting. A Participant’s vested interest in the Participant’s PPA Component Supplemental Retirement Benefit calculated under this Section 3.2 (i.e., vesting percentage) shall be determined in accordance with the applicable vesting terms contained in the DEPP.

d.Cessation of Accruals. No Participant shall earn additional Pay Credits on or after January 1, 2024. However, the PPA Component Supplemental Retirement Benefit of each Participant who has not commenced a benefit in accordance with Article IV as of December 31, 2023, shall continue to be credited with Interest Credits through the Participant’s benefit commencement date. The above shall apply regardless of whether the Participant’s benefit under the DEPP was transferred to the Dow Employees’ Pension Plan (Personal Pension Account) immediately following the end of the DEPP’s plan year occurring on December 31, 2023. For any such Participant whose benefit was transferred, “DEPP” as used in Section 3.2, Section 3.3, and Section 4.1(b) shall mean, effective on and after January 1, 2024, the Dow Employees’ Pension Plan (Personal Pension Account).

Except as otherwise provided in the Plan, actuarial equivalence under the Plan shall be determined using the applicable actuarial factors in the DEPP as of the determination date.

There shall be no duplication of benefits payable under this Plan and under any other plan sponsored by the Company, except as otherwise determined to be appropriate by the Plan Administrator. If a Participant, Spouse or other Beneficiary, or alternate payee, if any, shall be eligible for a benefit under any such other plan and shall also be eligible for a benefit hereunder based upon the same period of service by the Participant, then the amount of such other benefit due or paid to such Participant, Spouse, or other Beneficiary (or the actuarial equivalent thereof where necessary or appropriate) shall be deducted from the benefit payable hereunder for such period of service, except as otherwise determined by the Plan Administrator. The Plan Administrator is further authorized to offset any benefit due hereunder as a result of benefits due or paid to a Participant, Spouse, or other Beneficiary under another plan sponsored by the Company.

a.DEPP Component Supplemental Retirement Benefits. Subject to the special rules provided in this Section 4.1, a Participant’s vested DEPP Component Supplemental Retirement Benefits shall be payable in one of the actuarially equivalent life annuities described below. In the event the Participant does not select a form of payment, the following default provisions will apply. If a Participant is married or has a domestic partner (as defined in the DEPP) when the Participant Separates from Service, then the Participant’s vested DEPP Component Supplemental Retirement Benefits shall be paid in the form of a 100% joint and survivor annuity. If a Participant does not have a Spouse or domestic partner when the Participant Separates from Service, then the Participant’s vested DEPP Component Supplemental Retirement Benefits shall be paid in the form of a single life annuity. A Participant may elect an optional form of payment from the list of actuarially equivalent life annuities (within the meaning of Treas. Reg. section 1.409A-2(b)(2)(ii)) described below. The election of an optional form of payment by the Participant shall be made without regard to the timing or form of payment elected by the Participant under the DEPP and must occur prior to the month in which benefit payments under the Plan are scheduled to commence.

The optional forms of payment are:

i.Single life annuity

ii.50% joint and survivor annuity

iii.100% joint and survivor annuity

To the extent the Participant is eligible to elect it, any of the three options described above – single life annuity, 50% joint and survivor annuity, or 100% joint and survivor annuity – with a Guaranteed Payout Option.

The Guaranteed Payout Option is an additional option elected in conjunction with one of the life annuities otherwise available as a form of distribution under the Plan. The Guaranteed Payout Option provides reduced benefits that are payable monthly during the Participant’s and surviving annuitant’s lifetime(s), with any remaining guaranteed payout amount paid in the form of a single lump sum payment in the first month following the death of the last annuitant. Unless a Participant has (i) accrued less than 10 years of Eligibility or Vesting Service (as determined under the DEPP) and (ii) is considered Totally Disabled as defined under the DEPP, a Participant may elect the Guaranteed Payout Option.

The amount of the guaranteed payout shall equal the excess, if any, of (i) the Participant’s account balance from a vested DEPP Component Supplemental Retirement Benefit determined on the date the Participant Separates from Service over (ii) the sum of all monthly benefit payments made before the date of death of the last annuitant to die. The

Guaranteed Payout amount shall be paid to the Participant’s remaining Beneficiary as determined in Section 1.3.

b.PPA Component Supplemental Retirement Benefits. A Participant’s vested PPA Component Supplemental Retirement Benefits payable under the Plan shall be paid in the form of a single lump sum payment following the Participant’s Separation from Service. Payment of the PPA Component Supplemental Retirement Benefit shall be made without regard to the timing or form of payment elected by the Participant under the DEPP.

c.Small Benefits. Notwithstanding the provisions in this Section 4.1, if the present value of a Participant’s vested DEPP Component Supplemental Retirement Benefits as of the date the Participant Separates from Service is equal to or less than $100,000, such benefits will instead be paid as a single lump sum payment at the time provided in Section 4.2(c). If a Participant has a benefit under this Plan and The Dow Chemical Company Executives’ Supplemental Retirement Plan — Restricted and Cadre Benefits, such benefits will be aggregated for purposes of determining if the $100,000 threshold is met, to the extent required by Code section 409A. This Section 4.1(c) shall apply, to the extent permitted by Code section 409A, with respect to benefits to which the Participant accrues a legally binding right on or after the closing date of the transaction described in the Agreement and Plan of Merger.

a.DEPP Component Supplemental Retirement Benefits. Subject to the delay for Key Employees, vested DEPP Component Supplemental Retirement Benefits accrued under the Plan shall be payable commencing in the first month following the Participant’s Separation from Service.

b.PPA Component Supplemental Retirement Benefits. A Participant’s vested PPA Component Supplemental Retirement Benefits accrued under the Plan shall be payable in the seventh month following the Participant’s Separation from Service.

c.Small Benefits. Subject to the delay for Key Employees, a Participant’s vested DEPP Component Supplemental Retirement Benefits that satisfy the description of small benefits in Section 4.1(c) shall be paid as a single lump sum in the third month following the Participant’s Separation from Service.

d.Delay for Key Employees. Notwithstanding the foregoing, if the Participant is a Key Employee, then upon the Participant’s Separation from Service, distribution of the Participant’s vested DEPP Component Supplemental Retirement Benefits shall be delayed until the seventh month following the date of the Participant’s Separation from Service (or if earlier, the date of the Participant’s death). Amounts otherwise payable to the Participant during such period of delay shall be accumulated and paid in the seventh month following the Participant’s Separation from Service, along with interest on the delayed payments.

a.Eligibility and Payment. Notwithstanding any other provision of the Plan, a Participant who is eligible for DEPP Component Supplemental Retirements Benefit may receive such

benefits in the form of a Lump Sum Distribution if the Participant meets the eligibility requirements of this Section 4.3. A “Lump Sum Distribution” is a single payment that is payable in the amount, on the terms, and under the conditions set forth in this Section 4.3.

i.Eligibility. A Participant shall be eligible to elect a Lump Sum Distribution only if the Participant meets the written eligibility requirements that are established by The Dow Chemical Company (acting through the CHRO or another officer, employee or committee to whom this responsibility is delegated), and that are in effect on the date the Participant submits the Participant’s election pursuant to this Section 4.3. A Participant shall be notified in writing of the Participant’s eligibility to elect a Lump Sum Distribution.

ii.Election of Lump Sum Distribution. A Participant who is eligible and wishes to elect a Lump Sum Distribution shall make the Participant’s election in writing, on a form provided by the Plan Administrator for such purpose, and shall submit the Participant’s election to the Plan Administrator at least 12 months before the Participant’s Separation from Service Date.

If such Participant Separates from Service prior to the 12-month anniversary of the date the Participant submitted the Participant’s written election, the Participant’s election shall be disregarded and the Participant’s benefit shall be payable, if at all, in accordance with Section 4.1.

iii.Payment Date. A Lump Sum Distribution validly elected under this Section 4.3 shall be paid on the first day of the first month following the fifth anniversary of the Participant’s Separation from Service Date. For the avoidance of doubt, such date of payment is intended to comply, and shall be construed to comply, with Code section 409A(a)(4)(C)(ii).

iv.Death. If a Participant who has validly elected a Lump Sum Distribution dies after Separation from Service but before such Lump Sum Distribution is paid to the Participant, the Participant’s Beneficiary shall be paid an amount based on the Lump Sum Distribution determined under this Section 4.3. Such amount shall be paid on the first day of the month immediately following the month in which the Participant’s death occurs.

If a Participant who has elected a Lump Sum Distribution dies before Separation from Service, the Participant’s election shall be void and the Participant’s Beneficiary shall receive the payment set forth in Section 4.5(a).

If a Participant dies after receiving a Lump Sum Distribution, no death benefit shall be payable from the Plan on the Participant’s behalf.

v.No Other Payments. Any amount paid to a Participant or the Participant’s Beneficiary under this Section 4.3 shall represent the full benefit payable under the Plan to such Participant or Beneficiary, and shall be in lieu of any other payment that otherwise would have been made under the terms of the Plan.

b.Amount of Lump Sum Distribution. If a Participant is eligible for a Lump Sum Distribution under Section 4.3(a), the amount of the Participant’s Lump Sum Distribution shall equal the Participant’s DEPP Lump Sum Benefit, increased with interest from the Participant’s Lump Sum Determination Date through the payment date at the rate of return, compounded monthly, under the Ten-Year U.S. Treasury Note Plus Fund established under The Dow Chemical Company Elective Deferral Plan (Post-2004) (the “EDP”), or the comparable fund under the EDP if the Ten-Year U.S. Treasury Note Plus Fund is no longer offered under the EDP.

The Participant’s “Lump Sum Determination Date” is the first day of the month immediately following the month in which such Participant’s Separation from Service Date occurs.

The Participant’s DEPP Lump Sum Benefit equals:

i.The amount of the Participant’s Current Formula Benefit calculated as provided in article IV of DEPP as of the Participant’s Separation from Service Date, but determined: (A) by using Compensation as defined in this Plan rather than compensation as defined in DEPP; (B) without regard to the benefit limitations under Code section 415; and (C) before the application of the Benefit Conversion Factor or, solely for Lump Sum Determination Dates that occur before January 1, 2024, the crediting of any interest under DEPP

minus:

ii.The amount of the Participant’s Current Formula Benefit calculated as provided in article IV of DEPP as of the Participant’s Separation from Service Date but before the application of the Benefit Conversion Factor or, solely for Lump Sum Determination Dates that occur before January 1, 2024, the crediting of any interest under DEPP,

iii.The benefit paid to the Participant from the Plan in connection with the change of control resulting from the Orion Merger, and

iv.Any other benefit paid to the Participant under the Plan.

Notwithstanding the foregoing, in the event of a Change of Control, a Participant’s vested DEPP Component Supplemental Retirement Benefit and vested PPA Component Supplemental Retirement Benefits accrued under this Plan shall become payable immediately and shall be paid as a single lump sum payment within 90 days after the Change of Control; provided, that the Participant shall not be able to designate the tax year in which such lump sum payment will occur. This Section 4.4 shall not apply to Participants who are employees of Dow Corning Corporation in the case of a Change of Control that occurs prior to January 1, 2018.

a.Death Prior to Commencement of Benefit Payments. In the event of a Participant’s death before the month in which benefit payments commence under Section 4.2, death benefits equal to the Participant’s vested DEPP Component Supplemental Retirement Benefits and vested PPA Component Supplemental Retirement Benefits shall be paid in the first month following the month in which the Participant dies. The death benefit shall be payable in a lump sum to the Participant’s Beneficiary.

b.Death After Commencement of Benefit Payments. In the event of a Participant’s death after benefit payments have commenced under Section 4.2, the death benefit, if any, payable hereunder shall be paid in accordance with the applicable form of payment specified in Section 4.1(a) and any optional form of payment elected by the Participant (if applicable).

A Participant’s benefits shall be paid earlier than the date(s) specified in Sections 4.2, 4.3, or 4.4 under the following circumstances, each only to the extent permitted under Code section 409A:

a.Ethics Agreement. To the extent necessary for the Participant to comply with an ethics agreement with the Federal government, and to the extent reasonably necessary to avoid the violation of applicable Federal, state, or local ethics law or conflicts of interest law, to the extent permitted by Treas. Reg. section 1.409A-3(j)(4)(iii);

b.Income Tax Obligations. To comply with state, local, or foreign tax obligations that apply to amounts deferred under the Plan before the amounts are paid or made available to the Participant, to the extent permitted by Treas. Reg. section 1.409A-3(j)(4)(xi);

c.FICA Obligations. To the extent necessary to pay FICA tax on compensation deferred under the Plan and to pay federal state, local, or foreign income tax at the source on wages resulting from the payment of such FICA tax, to the extent permitted by Treas. Reg. section 1.409A-3(j)(4)(vi);

d.Section 409A Violations. To the extent required to be included in income as a result of a violation of Code section 409A, to the extent permitted by Treas. Reg. section 1.409A-3(j)(4)(vii);

e.Debt Owed to the Company. To the extent necessary to satisfy a debt of the Participant to the Company and to the extent permitted by Treas. Reg. section 1.409A-3(j)(4)(xiii), where (i) such debt is incurred in the ordinary course of the employee-employer relationship, (ii) the entire amount used to satisfy such debt in any fiscal year of the Company does not exceed $5,000, and (iii) the offset against such debt is made at the same time and in the same amount as such debt otherwise would have been due and collected from the Participant;

f.Disputed Amounts. To the extent of any settlement between the Company and the Participant of an arm’s length bona fide dispute as to the Participant’s right to a deferred compensation amount under the Plan, and to the extent permitted by Treas. Reg. section 1.409A-3(j)(4)(xiv); provided, that such settlement amount is at least 25 percent less than the present value of the disputed amount and is not made at the same time as or proximate to a downturn in the financial health of the Employer; and

g.Other Permissible Circumstances. In the sole discretion of the Plan Administrator, under any other circumstance permitted under Code section 409A.

Notwithstanding any other provision of the Plan, amounts payable hereunder may be delayed after the date(s) specified under this Article IV under the following circumstances, each to the extent permitted under Code section 409A:

a.Section 162(m). Payment may be delayed if the Company reasonably anticipates that if a payment were made as scheduled, the Company’s deduction with respect to such payment would not be permitted under Code section 162(m); provided, that payment shall be made upon the earlier of (i) the earliest date upon which the Company reasonably anticipates that the Company’s deduction of the payment will not be limited or eliminated by the application of Code section 162(m) and (ii) if the Participant experiences a Separation from Service, as soon as practicable following such Separation from Service in the calendar year of such Separation from Service (or, if later, no later than 2½ months following Separation from Service), subject to the delay, if applicable, set forth in Section 4.2(d).

b.Federal Securities Laws. Payment may be delayed if the Company reasonably anticipates that the making of a payment would violate Federal securities laws or other applicable law; provided, that the payment is made at the earliest date at which the Company reasonably anticipates that the making of the payment will not cause such violation; and

c.Other Events as Permitted by Section 409A. Payment may be delayed upon such other events or conditions as may be permitted in regulations or other guidance issued under Code section 409A.

a.Domestic Relations Orders. Upon receipt of a valid domestic relations order, as determined by the Plan Administrator pursuant to Treas. Reg. section 1.409A-3(j)(4)(ii) and the domestic relations order procedures applicable to the Plan (the “Procedures”), that requires distribution of all or a portion of a Participant’s vested benefit under the Plan to an alternate payee, the required distribution(s) shall be paid to the alternate payee in accordance with such order, to the extent not already paid to a Participant or Beneficiary. Except as otherwise provided in the Procedures, however, a domestic relations order shall be valid with respect to the Plan only if it is a shared payment order (i.e., it assigns to an alternate payee all or a portion of the benefit payments that will be paid to the Participant if, as and when they are paid to the Participant). References in the Plan to Participants shall include alternate payees to the extent required by an applicable valid domestic relations order.

b.Incompetence. If the Plan Administrator determines that any person entitled to receive benefits hereunder is not physically or mentally capable of electing the time or form, or receiving or acknowledging receipt, of benefits under the Plan, the Plan Administrator may make benefit payments to the court-appointed legal guardian of the such person, to an individual who has become the legal guardian of such person by operation of state law, or to another individual whom the Plan Administrator determines is the appropriate person to receive such benefits on behalf of the person entitled to receive benefits.

c.Unclaimed Payments and Lost or Missing Participants. Benefits that the Plan is unable to pay because a Participant, Beneficiary, Spouse, domestic partner, or other intended recipient has not been located, and benefit payments made by checks that are not cashed or deposited or by electronic funds transfers or other payment methods that are not completed and any benefits to which such benefit payments relate, shall be forfeited if the Plan is not able to locate the intended recipient, or the payment is not completed, within one year after the Plan first attempts to make the payment. The Plan Administrator is entitled to rely on the last address provided to the Plan by the intended recipient and has no obligation to search for or ascertain such individual’s whereabouts.

d.Incorrect Payment of Benefits. If the Plan Administrator determines in its sole discretion that the Plan made an overpayment of the amount of any benefits due any payee under the Plan, and that a correction is necessary or desirable under the law, then to the extent permitted by Code section 409A, the Plan may recover the amounts either by requiring the payee to return the excess to the Plan, by reducing any future Plan payments to the payee or by any other method deemed reasonable by the Plan Administrator.

e.Administrative Delay. The Plan Administrator may make payment on any day later than the date specified in the Plan as a result of administrative delay to the extent that such payment is treated as being paid on the date specified in the Plan under Treas. Reg. section 1.409A-3(d), which generally permits payment to be made later within the same calendar year, or, if later, within 2½ months following the date specified in the Plan, provided that the Participant is not permitted to designate the taxable year of payment.

If a Participant or Beneficiary believes they are entitled to have received a benefit but has not received payment, the Participant or Beneficiary must accept any payment made under the Plan and make prompt, reasonable, good faith efforts to collect the remaining portion of the payment, as determined under Treas. Reg. section 1.409A-3(g). For this purpose (and as determined under such regulation), efforts to collect the payment will be presumed not to be prompt, reasonable, good faith efforts unless the Participant or Beneficiary provides notice to the Plan Administrator within 90 days of the latest date upon which the payment could have been timely made in accordance with the terms of the Plan and the regulations under Code section 409A, and unless, if not paid, the Participant or Beneficiary takes further enforcement measures within 180 days after such latest date. The requirements of this Section 4.9 shall be in addition to, and shall not supersede or be superseded by, the provisions of Section 6.5.

Notwithstanding any other provision of the Plan and unless expressly prohibited under Code section 409A, the benefit under this Plan is subject to the Dow Inc. Compensation Clawback Policy and any successor policy and any related policies adopted by the Company or Dow Inc. from time to time (the “Clawback Policy”). For the avoidance of doubt, the Clawback Policy may provide for the recalculation of the benefit amount determined hereunder and/or the recoupment of any amounts previously paid. This Section 4.10 shall not affect the Company’s (or Dow Inc.’s) ability to pursue any other available rights and remedies under applicable law.

The entire cost of providing benefits under the Plan shall be paid by the Company out of its current operating budget, and the Company shall not be required under any circumstances to fund its obligations under the Plan. Notwithstanding the foregoing, the Company may, at its sole option, informally fund its obligations under the Plan in whole or in part by the creation of book reserves, the establishment of a grantor trust, the purchase of insurance and other assets, or by other means. In no event shall any Participant or Beneficiary have any incidents of ownership of any such insurance contracts or other assets. In addition, no Participant or Beneficiary shall be named a beneficiary under any such insurance contract. If the Company informally funds the Plan, in whole or in part, the manner of such informal funding and the continuance or discontinuance of such informal funding shall be in the sole discretion of the Company.

Participants and Beneficiaries shall be regarded as unsecured general creditors of the Company with respect to any rights derived by the Participants and Beneficiaries from the existence of the Plan. Title to and beneficial ownership of any Company assets (including any assets that may be held in trust) which may be used to satisfy the Company’s obligation for payment of benefits shall remain solely that of the Company.

Nothing in this Plan shall constitute the creation of a trust or other fiduciary relationship between the Company, its agents, representatives or other employees dealing with the Plan and any Participant, Beneficiary, or other person. The obligations of the Company under the Plan shall be limited to an unfunded and unsecured promise to pay.

Except as provided in Section 4.8(a) (regarding domestic relations orders), no benefit under the Plan shall be subject in any manner to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance, or charge, and any such attempt shall be void; nor shall any such benefit be in any manner liable for or subject to the debts, contracts, liabilities, or engagements, except as may be legally required.

This Section 5.4 shall not prevent the obligations and rights of the Company under this Plan to be encumbered in the event of the Company’s insolvency.

The Plan Administrator shall be responsible for the administration of the Plan and shall have the exclusive power and authority to control and manage the operation and administration of the Plan. However, any discretionary actions regarding Section 16 Employees, as defined by the Securities Exchange Act of 1934 and determined by the Plan Administrator, are reserved for the board of directors of Dow Inc. (or any successor).

The principal duty of the Plan Administrator shall be to see that the Plan (including, for the avoidance of doubt, Appendix A) is carried out in accordance with its terms. Except as provided in Sections 6.2 and 6.5, the responsibility and authority of the Plan Administrator shall include, but shall not be limited to, the following duties and powers:

a.To promulgate and enforce such rules and regulations and prescribe the use of such forms as the Plan Administrator shall deem necessary or appropriate for the proper and efficient administration of the Plan;

b.To interpret the Plan and to resolve any possible ambiguities, inconsistencies and omissions therein or therefrom;

c.To decide all questions of fact arising under the Plan;

d.To prepare and disseminate communications to Participants and Beneficiaries as are necessary or appropriate to properly administer the Plan;

e.To retain third party administrators, consultants, accountants, actuaries, and other individuals or entities as the Plan Administrator deems necessary or advisable to assist the Plan Administrator in fulfilling the Plan Administrator’s responsibilities under the Plan, consistent with The Dow Chemical Company’s guidelines on hiring and retention of outside service providers, monitor the performance of such individuals and entities, decide whether to discontinue the services of such individuals and entities, and make payment to such individuals and entities in accordance with the terms of the Plan; and

f.To settle or compromise any claim or dispute involving the Plan and enforce any release of a claim against the Plan or any covenant not to sue the Plan.

a.Designation of additional administrators. The Dow Chemical Company, as the Plan sponsor, may designate one or more persons, groups of persons, or entities to serve as the Plan Administrator, Initial Claims Reviewer, or Appeals Administrator, in addition to or in lieu of the Plan Administrator, Initial Claims Reviewer, or Appeals Administrator named in the plan document, through an action of the Board or through a written designation signed by the CHRO or the Sponsor Representative, each acting individually, or such other person

as the Board shall designate. Any such designation shall set forth in general or specific terms such designee’s responsibilities and authority.

b.Allocation of administrative responsibilities. The Plan Administrator(s) may allocate their administrative responsibilities in a written document delineating the responsibilities and authority assigned to each administrator and, if applicable, the period for which such allocation shall be in effect. Similarly, if the Initial Claims Reviewer or the Appeals Administrator consists of more than one person, group of persons, or entity, such Initial Claims Reviewer or Appeals Administrator may allocate its administrative responsibilities among such persons, groups of persons, or entities in a written document delineating the responsibilities and authority assigned to each and, if applicable, the period for which such allocation shall be in effect.

c.Delegation of administrative responsibilities. The Plan Administrator(s), Initial Claims Reviewer, and Appeals Administrator may designate other persons, groups of persons, or entities to carry out their responsibilities under the Plan in a writing that sets forth the responsibilities assigned to the delegee and, if applicable, the period for which such delegation shall be in effect. Any such delegation shall set forth in general or specific terms the delegee’s responsibilities and authority, and the delegee shall acknowledge in writing that the delegee has agreed to take on such responsibility.

d.Authority of additional administrators and delegees. Unless the instrument designating an administrator or delegating authority to a delegee specifies otherwise, the designee or delegee shall have the same discretionary powers in carrying out such allocated or delegated responsibility as the allocator or delegor would have if it had carried out the responsibility itself, and the provisions of Section 6.3 shall apply to the administrator or delegee.

a.The Plan Administrator, Initial Claims Reviewer, and Appeals Administrator shall have the sole and absolute discretion to interpret Plan documents, make findings of fact, and decide any matters arising with respect to their assigned duties and powers under the Plan, and may adopt such rules and procedures as they deem necessary, desirable or appropriate to carry out their responsibilities under the Plan. In particular: (i) the Plan Administrator shall have the sole and absolute discretion to decide administrative issues and to exercise the duties and powers set forth in Section 6.1 and shall have such discretionary power as may be necessary in order to carry out those duties and powers; and (ii) the Initial Claims Reviewer and Appeals Administrator shall have the sole and absolute discretion to decide claims and appeals as described in Section 6.5 and to exercise the duties and powers set forth in Section 6.5, and shall have such discretionary power as may be necessary in order to carry out those duties and powers.

b.The determinations and rules of the Plan Administrator, Initial Claims Reviewer, and Appeals Administrator or other administrator upon any question of fact, interpretation, definition, or procedure relating to the Plan or any other matter relating to the Plan shall be conclusive and binding on all persons having an interest in the Plan, except that (i) the determinations of the Initial Claims Reviewer are subject to review by the Appeals Administrator; and (ii) the determinations of the Initial Claims Reviewer and the Appeals

Administrator are subject to the interpretations of the Plan document by the Plan Administrator. If challenged in court, the determinations of the Plan Administrator, Initial Claims Reviewer, and Appeals Administrator shall not be subject to de novo review and shall not be overturned unless proven to be arbitrary and capricious based upon the evidence presented to or considered by Plan Administrator, Initial Claims Reviewer, or Appeals Administrator at the time of its determination.

The Plan Administrator, Initial Claims Reviewer, Appeals Administrator, any delegee of the Plan Administrator, Initial Claims Reviewer, or Appeals Administrator (irrespective of whether such delegation is provided in writing, orally, or by action), and any officer, employee, or former employee of a Company who acts on behalf of the Plan Administrator, Initial Claims Reviewer, Appeals Administrator, or delegee with respect to the Plan, is entitled to all indemnification rights provided to a person in these roles under The Dow Chemical Company’s Bylaws (and any future enhancements to those rights), including indemnification under section 6.1 and section 6.2 of The Dow Chemical Company’s Bylaws (or any successor provisions thereto). Notwithstanding the foregoing, nothing in this indemnification provision extends any indemnification rights to any third-party service providers, except for any indemnification rights that may be provided in written contracts between The Dow Chemical Company or the Plan and such third-party service providers.

a.Initial Claims. If the Initial Claims Reviewer receives a written claim for benefits from a Participant or other individual, the Initial Claims Reviewer shall review such claim in accordance with this Section 6.5. If the Initial Claims Reviewer determines that such claim should be denied in whole or in part, the Initial Claims Reviewer shall, in writing, notify such claimant within 90 days of receipt of such claim that the claimant’s claim has been denied, unless special circumstances require an extension of time for processing. If an extension is required, the Initial Claims Reviewer shall give the claimant written notice and reason for the need for extension and the date by which a decision is expected within the original 90-day period. In no event shall the decision take longer than 180 days after receipt of the claim. If the claim is denied, the Initial Claims Reviewer shall set forth in writing the specific reasons for such denial and such notification shall:

i.state the reason why the claim is being denied;

ii.set forth the pertinent sections of the Plan relied upon;

iii.if applicable, set forth an explanation of any additional material or information necessary for the claimant to perfect the claimant’s claim and an explanation of why such material or information is necessary; and

iv.set forth an explanation of how the claimant can obtain review of such denial, including a statement of the claimant’s right to bring a civil action following an adverse benefit determination.

The claimant may submit written comments, documents, records, and other information relating to the claim for benefits. Further, the claimant shall be provided, upon request, and

free of charge, reasonable access to, and copies of, all documents, records and other information relevant to the claimant’s claim for benefits.

b.Appeals. Within 60 days after receipt by the claimant of such notice, such claimant may request, by mailing or delivery of written notice to the Appeals Administrator, a review by the Appeals Administrator of the decision denying the claim. If the claimant fails to request such a review within such 60-day period, it shall be conclusively determined for all purposes of this Plan that the denial of such claim by the Initial Claims Reviewer is correct.

The Appeals Administrator shall notify a claimant of its determination on appeal within a reasonable period of time, but not later than 60 days after receipt of the claimant’s request for review, unless the Appeals Administrator determines that special circumstances require an extension of time for processing the appeal. If the Appeals Administrator determines that an extension of time for processing the appeal is required, written notice of the extension shall be furnished to the claimant prior to the termination of the initial 60-day period. In no event shall such extension exceed a period of 60 days from the end of the initial period. The extension notice shall indicate: (i) the special circumstances necessitating the extension and (ii) the date by which the Appeals Administrator expects to render a determination.

If the claim is denied, the Appeals Administrator shall set forth in writing the specific reasons for such denial and such notification shall:

i.state the reason for denial of the claim;

ii.set forth the pertinent Sections of the Plan relied upon; and

iii.state that the claimant may bring a civil action under ERISA section 502(a) in federal court, provided the claimant institutes such legal proceeding within the time periods provided in Section 6.6.

The claimant shall be provided, upon request, and free of charge, reasonable access to, and copies of, all documents, records, and other information relevant to the claimant’s claim for benefits.

A claim for a benefit under this Section 6.5 shall include any Applicable Claim as defined in Section 6.6.

a.An Applicable Claim may not be filed in any court until the claimant has exhausted the claims review procedures described in Section 6.5, and unless such claim or action is filed in a court with jurisdiction over such claim or action no later than the earlier of: (I) 180 days after the mailing or delivery of the adverse determination by the Appeals Administrator; or (II) one year after:

i.in the case of a claim or action to recover benefits allegedly due to the claimant under the terms of the Plan or to clarify the claimant’s rights to future benefits under the terms of the Plan, the earliest of (A) the date the first benefit payment was

actually made, (B) the date the first benefit payment was allegedly due, and (C) the date the Plan first repudiated its alleged obligation to provide such benefits (regardless of whether such repudiation occurred before or during the administrative review process),

ii.in the case of a claim or action to enforce an alleged right under the Plan (other than a right to benefits which are subject to Section 6.6(a)(i)), the date the Initial Claims Reviewer or Appeals Administrator first denied the claimant’s request to exercise such right, regardless of whether such denial occurred during the administrative review process,

iii.in the case of any other claim or action described in Section 6.6(b)(iv), the earliest date on which the claimant knew or should have known of the material facts on which such claim or action is based, regardless of whether the claimant was aware of the legal theory underlying the claim or action;

provided, that if a request for administrative review, timely made in accordance with Section 6.5, is pending before the Initial Claims Reviewer or Appeals Administrator when the period described in this Section 6.6 expires, the deadline for filing such claim or action in a court with proper jurisdiction shall be extended to the date that is 180 days after the mailing or delivery of the adverse determination by the Appeals Administrator.

The period described by this Section 6.6 is hereafter referred to as the “Applicable Limitations Period.” The Applicable Limitations Period replaces and supersedes any limitations period ending at a later time that might otherwise be deemed applicable under state or federal law in the absence of this Section 6.6. Except as provided in the following two sentences, a claim or action filed after the expiration of the Applicable Limitations Period shall be deemed time-barred. The Applicable Limitations Period may be extended by the CHRO or the CHRO’s designee in their sole discretion upon a showing of exceptional circumstances that, in the opinion of the CHRO or the CHRO’s designee provide good cause for an extension. The exercise of this discretion is committed solely to the CHRO or the CHRO’s designee, and is not subject to review.

b.For purposes of this Section 6.6, an “Applicable Claim” is:

i.a claim or action to recover benefits allegedly due under the provisions of the Plan or by reason of any law,

ii.a claim or action to clarify rights to future benefits under the Plan,

iii.a claim or action to enforce rights under the Plan, or

iv.any other claim or action that (A) relates to the Plan, and (B) seeks a remedy, ruling, or judgment of any kind against the Plan, the Company, the Plan Administrator, the Initial Claims Reviewer, the Appeals Administrator or any delegee of the Plan Administrator, Initial Claims Reviewer or Appeals Administrator, or any officer, employee, or former employee of The Dow Chemical Company or any entity within the Dow Controlled Group or other person who acts on behalf of the Plan.

c.In the event of any Applicable Claim brought by or on behalf of two or more claimants, this Section 6.6, including the Applicable Limitations Period, shall apply separately with respect to each claimant.

a.To the fullest extent permitted by law, any putative class action lawsuit relating to the Plan, the lawfulness of any Plan provision, the administration of the Plan or the performance or non-performance of a Plan Administrator, Initial Claims Reviewer, Appeals Administrator, their delegees or any officer, employee or former employee of The Dow Chemical Company or any entity within the Dow Controlled Group or other persons who act on their behalf with respect to the Plan shall be filed in one of the following jurisdictions: (i) the jurisdiction in which the Plan is principally administered, which is currently within the territorial boundaries of the Northern Division of the United States District Court for the Eastern District of Michigan; or (ii) the jurisdiction in which the largest number of putative class members resides (or if that jurisdiction cannot be determined, the jurisdiction in which the largest number of class members is reasonably believed to reside).

b.If any putative class action within the scope of Section 6.7(a) is filed in a jurisdiction other than one of those described in Section 6.7(a), or if any non-class action filed in such a jurisdiction is subsequently amended or altered to include class action allegations, then the Plan, all parties to such action that are related to the Plan, including all alleged Participants and Beneficiaries, shall take all necessary steps to have the action removed to, transferred to or re-filed in a jurisdiction described in Section 6.7(a). Such steps may include, but are not limited to, (i) a joint motion to transfer the action; or (ii) a joint motion to dismiss the action without prejudice to its re-filing in a jurisdiction described in Section 6.7(a), with any applicable time limits or statutes of limitations applied as if the suit or class action allegation had originally been filed or asserted in a jurisdiction described in Section 6.7(a) at the same time that it was filed or asserted in a jurisdiction not described therein.

c.This provision does not relieve any putative class member from any obligation existing under the Plan or by law to exhaust administrative remedies before initiating litigation.

The Dow Chemical Company reserves the right to amend the Plan at any time, with or without notice, retroactively or prospectively, to the full extent permitted by law. An action to amend the Plan may be taken by: (a) resolution of the Board; (b) action of the Benefits Governance and Finance Committee, the President, Chief Financial Officer, CHRO, or Sponsor Representative, each acting individually; or (c) action of any other person or persons duly authorized by the Board to take such action.

Notwithstanding the foregoing: (i) an amendment that affects only Section 16 Employees, as defined by the Securities Exchange Act of 1934 and determined by the Plan Administrator, shall not be valid unless it is adopted or approved by the board of directors of Dow Inc. (or any successor); (ii) shall not reduce a Participant’s right to benefits accrued and vested under the Plan as of the effective date of such amendment; and (iii) no amendment of the Plan shall apply to amounts that were earned and vested (within the meaning of Code section 409A and regulations thereunder) under the Plan prior to 2005, unless the amendment specifically provides that it applies to such amounts. The purpose of this restriction is to prevent a Plan amendment from resulting in an inadvertent “material modification” to amounts that are “grandfathered” and exempt from the requirements of Code section 409A.

Any amendment of the Plan must be reviewed by an attorney in The Dow Chemical Company’s Legal Department.

The authority of the Benefits Governance and Finance Committee, the President, Chief Financial Officer, CHRO, and Sponsor Representative to amend the Plan under this Section 7.1 may not be delegated.

The Board reserves the right to terminate the Plan, subject to the conditions set forth in this Section 7.2. A plan termination pursuant to this Section 7.2 shall be performed in a manner consistent with the requirements of Code section 409A and any regulations or other applicable guidance issued thereunder.

Except as provided in this Section 7.2, no termination of the Plan shall reduce a Participant’s right to benefits accrued and vested under the Plan as of the effective date of such termination. Upon termination of the Plan, distributions shall be made to Participants and Beneficiaries in the manner and at the time described in Article IV, unless the Company determines in its sole discretion that all such amounts shall be distributed upon termination in accordance with the requirements of Code section 409A. Upon termination of the Plan, no further benefit accruals shall be permitted.

This Plan shall be binding upon and inure to the benefit of the Company, its successors, Participants, Beneficiaries, and their respective successors, assigns, heirs, personal representatives, executors, administrators, and legatees.

a.Nothing contained herein shall in any manner affect any employment relationship between the Company and any Employee or other individual, nor shall anything contained herein be construed to enlarge upon or to add, directly or indirectly, to the employment rights of any individual, except the right to become eligible to become a Participant under the Plan subject to and as provided in the Plan document.

b.The action of the Company in creating or amending the Plan or any other action, either by the Company or by its employees, contemplated hereunder shall not be construed to constitute or evidence any employer-employee relationship between the Company and its employees. The Company shall have the absolute right at any time to deal with any of its employees from the standpoint of the employer-employee relationship as if the Plan had never been created.

The Plan shall be administered, construed and enforced in accordance with ERISA, and to the extent that ERISA has not preempted the laws of the State of Texas, the laws of the State of Texas shall apply, excluding any conflicts or choice of law rule or principle that might otherwise refer construction or interpretation of this provision to the substantive law of another jurisdiction.

The Company shall have the right to withhold taxes from any payments made pursuant to the Plan, or make such other provisions as it deems necessary or appropriate to satisfy its obligations to withhold federal, state, local, or foreign income or other taxes incurred by reason of payments pursuant to the Plan. In lieu thereof, the Company shall have the right, to the extent permitted by Code section 409A and other provisions of law, to withhold the amount of such taxes from any other sums due or to become due from the Company to the Participant or any Beneficiary, upon such terms and conditions as the Company may prescribe.

If any provision of the Plan should be held illegal or invalid for any reason, such illegality or invalidity shall not affect the remaining parts of the Plan, and the Plan shall be construed and enforced as if such illegal or invalid provision had never been inserted herein.

No notice, election, or communication in connection with the Plan made or submitted by any Participant, Employee, claimant or other person shall be effective unless duly executed and filed with the Plan Administrator in the form and manner required by the Plan Administrator.

No term, condition, or provision of the Plan shall be deemed waived unless the purported waiver is in writing signed by the Plan Administrator. No waiver signed by the Plan Administrator shall be deemed a continuing waiver unless so specifically stated in the writing, and any such waiver shall operate only for the stated period and only as to the specific term, condition, or provision waived.

The Company, Plan Administrator, Initial Claims Reviewer, Appeals Administrator, and any person to whom the Plan’s operation or administration is delegated may rely conclusively on any advice, opinion, valuation, or other information furnished by any actuary, accountant, appraiser, legal counsel, or physician whom such entity or person engages or employs. A good faith action or omission based on this reliance is binding on all parties, and no liability can be incurred for it except as the law requires.

Notwithstanding the other provisions hereof, the Plan shall be construed and interpreted to comply with Code section 409A and if necessary, any provision shall be held null and void to the extent such provision (or part thereof) fails to comply with Code section 409A or regulations thereunder. However, in no event shall the Plan, the Plan Administrator, the Initial Claims Reviewer, the Appeals Administrator, their delegees, the Company, its officers, directors, employees, former employees, parents, subsidiaries, or affiliates be liable for any additional tax, interest, or penalty incurred by a Participant, Beneficiary or any other person as a result of the Plan’s failure to satisfy the requirements of Code section 409A, or as a result of the Plan’s failure to satisfy any other applicable requirements for the deferral of tax.

a.Scrivener’s errors. The Plan shall be applied and interpreted without regard to any scrivener’s error in this instrument. The determination whether a scrivener’s error has occurred shall be made by the CHRO in the exercise of the CHRO’s best judgment and sole discretion, based on the CHRO’s understanding of the intent of The Dow Chemical Company as settlor of the Plan, and taking into account such evidence, written or oral, as the CHRO deems appropriate or helpful.
