(a) If prior to the commencement of any Interest Period for a Eurodollar Borrowing: 

(i) the Administrative Agent determines (which determination shall be conclusive absent manifest error) that adequate and
reasonable means do not exist for ascertaining the Adjusted LIBO Rate or the LIBO Rate (including, without limitation, because the LIBO Rate is not available or published on a current basis) for such Interest Period; or 

  
 THIRD AMENDMENT TO THIRD AMENDED
AND RESTATED CREDIT AGREEMENT – Page 2 

 (ii) the Administrative Agent is advised by the Majority Lenders that the
Adjusted LIBO Rate or LIBO Rate, as applicable, for such Interest Period will not adequately and fairly reflect the cost to such Lenders of making or maintaining their Loans included in such Borrowing for such Interest Period; 

then the Administrative Agent shall give notice thereof to the Borrower and the Lenders by telephone or facsimile as promptly as practicable
thereafter and, until the Administrative Agent notifies the Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, (x) any Interest Election Request that requests the conversion of any Borrowing to, or
continuation of any Borrowing as, a Eurodollar Borrowing shall be ineffective (and such Borrowing shall be automatically converted into ABR Loans on the last day of the applicable Interest Period), and (y) if any Borrowing Request requests a
Eurodollar Borrowing, such Borrowing shall be made either as an ABR Borrowing or at an alternate rate of interest determined by the Majority Lenders as their cost of funds. 

(b) If at any time the Administrative Agent determines (which determination shall be conclusive absent manifest error) that
(i) the circumstances set forth in clause (a)(i) above have arisen and such circumstances are unlikely to be temporary, or (ii) the circumstances set forth in clause (a)(i) have not arisen but (A) the supervisor for the
administrator of the LIBO Rate has made a public statement that the administrator of the LIBO Rate is insolvent (and there is no successor administrator that will continue publication of the LIBO Rate), (B) the administrator of the LIBO Rate has
made a public statement identifying a specific date after which the LIBO Rate will permanently or indefinitely cease to be published by it (and there is no successor administrator that will continue publication of the LIBO Rate), (C) the supervisor
for the administrator of the LIBO Rate has made a public statement identifying a specific date after which the LIBO Rate will permanently or indefinitely cease to be published or (D) the supervisor for the administrator of the LIBO Rate or a
Governmental Authority having jurisdiction over the Administrative Agent has made a public statement identifying a specific date after which the LIBO Rate may no longer be used for determining interest rates for loans, then Administrative Agent and
the Borrower shall endeavor to establish an alternative rate of interest to the LIBO Rate that gives due consideration to then prevailing market convention for determining a rate of interest for similarly situated loans in the United States at such
time, and shall enter into an amendment to this Agreement to reflect such alternative rate of interest and such other related changes to this Agreement as may be applicable (but for the avoidance of doubt, such related changes shall not include a
reduction of the Applicable Margin). Notwithstanding anything to the contrary in Section 12.02, such amendment shall become effective without any further action or consent of any other party to this Agreement so long as the
Administrative Agent shall not have received, within five Business Days of the date notice of such alternate rate of interest is provided to the Lenders, a written notice from the Majority Lenders stating that such Majority Lenders object to such
amendment. Until an alternate rate of interest shall be determined in accordance with this clause (b) (but, in the case of the circumstances described in clause (ii) of the first sentence of this
Section 3.03(b), only to the extent the LIBO Rate for such Interest Period is not 

  
 THIRD AMENDMENT TO THIRD AMENDED
AND RESTATED CREDIT AGREEMENT – Page 3 

 
available or published at such time on a current basis), (x) any Interest Election Request that requests the conversion of any Borrowing to, or continuation of any Borrowing as, a Eurodollar
Borrowing shall be ineffective, and (y) if any Borrowing Request requests a Eurodollar Borrowing, such Borrowing shall be made as an ABR Borrowing; provided that, if such alternate rate of interest shall be less than zero, such rate shall be
deemed to be zero for the purposes of this Agreement.” 
 (e) Article VII of the Original Credit Agreement shall be
amended by adding a new Section 7.27 thereto which shall read in its entirety as follows: 
 “Section 7.27
Beneficial Ownership Certification. As of the Third Amendment Effective Date, the information included in the Beneficial Ownership Certification, if applicable, is true and correct in all respects.” 

(f) Section 8.01(n) of the Original Credit Agreement shall be amended to read in its entirety as follows: 

“(n) Patriot Act. Promptly upon request, all documentation and other information reasonably requested by the
Administrative Agent or any Lender for purposes of compliance with applicable “know your customer” and anti-money laundering rules and regulations, including the Patriot Act and the Beneficial Ownership Regulation”. 

(g) Section 8.02 of the Original Credit Agreement is hereby amended by (i) deleting the word “and” at the
end of clause (c) thereof; (ii) deleting the period at the end of clause (d) thereof and inserting “; and” in lieu thereof; and (iii) adding a new clause (e) thereto to read in its entirety as follows: 

“(e) any change in the information provided in the Beneficial Ownership Certification delivered to the Administrative
Agent or such Lender that would result in a change to the list of beneficial owners identified in such certification.” 

(h) Section 8.20 of the Original Credit Agreement shall be amended to read in its entirety as follows: 

“Section 8.20 Swap Agreements. The Borrower shall, or shall cause a Subsidiary to, enter into and maintain in
effect, with one or more Approved Counterparties, a commodity price hedge position establishing minimum fixed prices acceptable to the Administrative Agent on a volume of Hydrocarbons equal to not less than 40% of the reasonably projected production
from proved, developed, producing Oil and Gas Properties of the Borrower and its Subsidiaries on a rolling 12-month basis; provided that, the Borrower may proportionally reduce its hedge position
through the termination or unwinding of Swap Agreements in connection with the sale of Oil and Gas Properties permitted pursuant to Section 9.10 such that the Borrower’s hedge position following such sale of Oil and
Gas Properties and corresponding reduction in hedge position shall cover a substantially similar percentage of the total volume of Hydrocarbons produced by the Borrower for the applicable periods as did the Borrower’s hedge position prior to
the sale of such Oil and Gas Properties and corresponding reduction in hedge position.”

and (ii) no Taxes will be allocated pursuant to this Section 2.4 for any Dow Authorization Policy Actions or DuPont Authorization Policy Actions (other than any actions described in clause (i) of the definition of Dow
Authorization Policy Actions or DuPont Authorization Policy Actions) if the aggregate Tax impact of such action for all applicable Tax Years (including the value of any lost Tax Attributes (valued using the same methodology as described in the
definition of “Tax Attribute Differential Value”), but excluding any Taxes described in clause (i) of this sentence) does not exceed $2,000,000. 

2.5 Compensation for Use of Attributes and Adjustment Payments. 

(a) Payment for Certain Attributes. If any Party or any of its Subsidiaries (at the time of payment) pays an amount to an employee,
pension or other third party, but the corresponding Tax Attribute is allocated by applicable law to another Party or any of its Subsidiaries at such time (including, without limitation, compensation paid or the granting of an equity interest to, or
the vesting of any equity interest granted to, an employee of the other Party or any of its Subsidiaries at such time, or any contributions in respect of a Party’s historic pension plan liabilities relating to a Realigned Entity) then the Party
to which the Tax Attribute 

  
 26 

 was allocated under applicable law (or the Party to whose Subsidiary the Tax Attribute was allocated) shall
make one or more payments to the Party that incurred the expense (or whose Subsidiary incurred the expense) in an amount equal to the actual reduction in Taxes of such Party or such Subsidiary (including reductions in Taxes allocated under this
Agreement), calculated on a “with and without” basis, to the extent that payment for such reduction in Taxes is not otherwise required pursuant to this Agreement. Any payments required to be made pursuant to this
Section 2.5(a), (i) between Dow and DowDuPont shall be made no later than sixty (60) days following the filing of the relevant Tax Return for the taxable period that includes the Dow Distribution if the reduction in Tax was
reflected on such Tax Return or a previously filed Tax Return, and (ii) between AgCo and SpecCo shall be made no later than ninety (90) days following the filing of the relevant Tax Return for the taxable period that includes the AgCo
Distribution if the reduction in Tax was reflected on such Tax Return or a previously filed Tax Return. If any payment described in the first sentence of this Section 2.5(a) is made after the close of the taxable period that includes the
Dow Distribution (in the case of payments pursuant to this Section 2.5(a) to be made between Dow, on one hand, and AgCo or SpecCo, on the other hand) or the AgCo Distribution (in the case of payments pursuant to this
Section 2.5(a) to be made between AgCo and SpecCo), the payment required to be made pursuant to this Section 2.5(a) shall be made no later than sixty (60) days following the filing of the Tax Return reflecting the actual
reduction in Taxes allocated to the paying Party (or such Party’s Subsidiary). Notwithstanding the foregoing, to the extent that the Tax Attribute is used to offset income included under Section 965 of the Code, the amount required to be
paid shall be equal to the present value of the installment payments under Section 965(h) of the Code that would otherwise have been made (assuming no available Tax Attributes of the entity, Dow or DuPont, as applicable, and its Subsidiaries
whose Tax Attributes offset such income inclusions attributable to the other entity and its Subsidiaries), and using a discount rate of four and one-half percent 4.5%. For purposes of this
Section 2.5(a), TDCC and its Subsidiaries as of any time shall be treated as Subsidiaries of Dow as of such time. 
 (b) Tax
Attributes for Section 336(e) Election. To the extent that a Party, other than the Party (or any of its Subsidiaries) benefiting from any Tax Attributes resulting from the Section 336(e) Election relating to the Dow Distribution, is
liable for Dow Distribution Taxes pursuant to this Agreement, then the Party that benefits from such Tax Attributes (or the Party whose Subsidiary benefits from such Tax Attributes) shall make one or more payments to the Party liable for the Dow
Distribution Taxes in an amount equal to the actual reduction in Taxes enjoyed by such Party or its Subsidiary (including reductions in Taxes allocated under this Agreement), calculated on a “with and without” basis. Any payments required
to be made pursuant to this Section 2.5(b) shall be made no later than sixty (60) days following the filing of the relevant Tax Return for the taxable period that includes the actual reduction in Taxes enjoyed by such Party or its
Subsidiary. 
 (c) U.S. Federal Income Adjustment Payment. No later than one hundred and twenty (120) days following the filing
of the U.S. federal income Tax Return for the DowDuPont U.S. Consolidated Group for the taxable year that includes the Dow Distribution, (i) if the Aggregate Adjustment Payment is negative, Dow shall pay the absolute value of the Aggregate
Adjustment Payment to DowDuPont, and (ii) if the Aggregate Adjustment Payment is positive, DowDuPont shall pay the Aggregate Adjustment Payment to Dow. 

  
 27 

 (d) U.S. State Consolidated Income Adjustment Payment. No later than one hundred and
fifty (150) days following the filing of the U.S. federal income Tax Return for the DowDuPont U.S. Consolidated Group for the taxable year that includes the Dow Distribution, (i) if the State Aggregate Adjustment Payment is negative, Dow
shall pay the absolute value of the State Aggregate Adjustment Payment to DowDuPont, and (ii) if the State Aggregate Adjustment Payment is positive, DowDuPont shall pay the State Aggregate Adjustment Payment to Dow. 

(e) No payment or further allocations shall be required under Section 2.1(a)(iii) or Section 2.1(b)(iii) by reason of any
payments made pursuant to Section 2.5(c)-(d). 
 2.6 Straddle Period Allocation. For purposes of this Agreement, if
either Realignment, the Dow Distribution or the AgCo Distribution occurs during a taxable period other than the last day of the taxable period, Taxes for the entire taxable period (including, for example, Subpart F income under Section 951 of
the Code and a proportionate share of the associated foreign tax credits) shall be allocated, on the one hand, to the portion of the taxable period ending on the Realignment Date, the Dow Distribution Date or the AgCo Distribution Date, as the case
may be, and on the other hand, to the portion of the taxable period beginning on the day after the Realignment Date, the Dow Distribution Date or the AgCo Distribution Date, as the case may be, on a “closing of the books” method as of the
end of the Realignment Date, the Dow Distribution Date or the AgCo Distribution Date; provided that property Taxes and other similar periodic Taxes, and exemptions, allowances or deductions that are calculated on an annual or periodic basis shall be
allocated between such portions in proportion to the number of days in each such portion. For the avoidance of doubt, the “closing of the books” method shall deem any tax period beginning before but ending after an applicable date to end
on the applicable date. If Realignment occurred during a taxable period, the Realigned Entity shall be treated as one entity for the portion of the taxable period up to and including the Realignment Date, and as a second, separate entity for the
portion of the taxable period beginning on the day following the Realignment Date. 
 2.7 Certain Distribution Taxes. 

(a) Distribution Taxes described in Section 2.1(a)(xi) and not in any of Section 2.1(b)(x),
Section 2.1(c)(vii) or 2.1(d)(vi) shall be allocated entirely to Dow; Distribution Taxes described in Section 2.1(b)(x) and not in any of Section 2.1(a)(xi), 2.1(c)(vii) or 2.1(d)(vi) shall be
allocated solely to DowDuPont; Distribution Taxes described in Section 2.1(c)(vii) and not in any of Section 2.1(a)(xi), 2.1(b)(x) or 2.1(d)(vi) shall be allocated solely to AgCo; and Distribution Taxes described in
Section 2.1(d)(vi) and not in any of Section 2.1(a)(xi), 2.1(b)(x) or 2.1(c)(vii) shall be allocated solely to SpecCo. Subject to Section 2.7(b), to the extent that any Distribution Taxes would, in the
absence of this Section 2.7(a), be described in both Section 2.1(a)(xi) and (i) Section 2.1(b)(x), or (ii) following the AgCo Distribution, Section 2.1(c)(vii) or
Section 2.1(d)(vi), responsibility for such Distribution Taxes shall be allocated to Dow, on the one hand, and DowDuPont, AgCo and/or SpecCo, as appropriate, on the other hand, according to relative fault. Subject to
Section 2.7(b), to the extent that any Distribution Taxes would, in the absence of this Section 2.7(a), be described in both Section 2.1(c)(vii) and Section 2.1(d)(vi), responsibility for such
Distribution Taxes shall be allocated to AgCo, on the one hand, and SpecCo, on the other hand, according to relative fault. 

  
 28 

 (b) Notwithstanding Section 2.7(a), in the case of Distribution Taxes resulting
from the application of Section 355(e) of the Code to a Distribution, (A) Dow shall be allocated one hundred percent (100%) of such Distribution Taxes if a Dow Disqualifying Action causes the application of Section 355(e), (B)
DowDuPont shall be allocated one hundred percent (100%) of such Distribution Taxes if a DowDuPont Disqualifying Action causes the application of Section 355(e), (C) SpecCo shall be allocated one hundred percent (100%) of such Distribution Taxes
if a SpecCo Disqualifying Action causes the application of Section 355(e) and (D) AgCo shall be allocated one hundred percent (100%) of such Distribution Taxes if an AgCo Disqualifying Action causes the application of Section 355(e).
In the event a Disqualifying Action of more than one Party causes the application of Section 355(e) to a Distribution, applicable Distribution Taxes shall be allocated among such Parties equally. 

ARTICLE III 
 TAX RETURNS, TAX
COMPLIANCE AND OTHER TAX MATTERS 
 3.1 Preparation of Tax Returns. 

(a) Each Party shall prepare and timely file, or cause to be prepared and timely filed, taking into account applicable extensions, all Tax
Returns required to be filed by such Party or any of its Subsidiaries (the “Preparing Party”) and shall pay, or cause to be paid, all Taxes shown as due and payable on such Tax Returns. To the extent that any such Tax Returns
reflect Taxes that are payable by another Party pursuant to this Agreement (the “Reviewing Party”), such Tax returns shall be prepared in accordance with the Past Practice of the Reviewing Party in respect of the entities or
operations giving rise to such Taxes. Except as otherwise required by applicable law, no Party shall file any amended Tax Return for a Realigned Entity for any taxable period ending on or before, or that includes, the Realignment Date of the
Realigned Entity, without the prior written approval (not to be unreasonably withheld, conditioned or delayed) of the Party responsible for Taxes relating to such periods pursuant to this Agreement. 

(b) The Preparing Party shall submit to the Reviewing Party a draft of any Tax Return that reflects Taxes payable by the Reviewing Party
pursuant to this Agreement (or to the extent practicable the portion of such Tax Return that relates to such Taxes) along with a statement setting forth the calculation of any such Taxes shown as due and payable on such Tax Return at least thirty
(30) days (or, in the case of a Tax Return with a Due Date fewer than fourty-five (45) days following the end of the taxable period to which such Tax Return relates, a reasonable amount of time) prior to the Due Date for such Tax Return
for such Reviewing Party’s review, comment and approval (such approval not to be unreasonably delayed, conditioned or withheld). 
 (c)
In the event of any dispute regarding any Tax Return, or any other matter referred to in this Agreement, the Tax Officer of each Party involved in the dispute shall cooperate in good faith to resolve such dispute. Any dispute that the Tax Officers
are unable to resolve shall be referred to a senior executive of each Party involved in the dispute who shall cooperate in good faith to resolve such dispute. Any dispute that such senior executives are unable to resolve shall be resolved by the
Dispute Resolution Firm pursuant to Section 8.1. In the 

  
 29 

 
event that any dispute is not resolved (whether pursuant to good faith cooperation or by the Dispute Resolution Firm) prior to the Due Date for the filing of any such Tax Return, such Tax Return
shall be timely filed by the Preparing Party and the Preparing Party agrees to amend such Tax Return as necessary to reflect the resolution of such dispute in a manner consistent with such resolution. 

(d) Notwithstanding anything to the contrary in this Agreement, for all Tax purposes, the Parties shall report any Extraordinary Transactions
that are caused or permitted to occur by a Party or any of their respective Subsidiaries on either the Dow Distribution Date or the AgCo Distribution Date as occurring on the day after the Dow Distribution Date or the AgCo Distribution Date, as
applicable, pursuant to Treasury Regulations Section 1.1502-76(b)(1)(ii)(B) or any similar or analogous provision of state, local or foreign law. Similar principles shall apply for purposes of making
allocations under this Agreement in respect of Extraordinary Transactions occurring on the Realignment Date after Realignment. The Parties hereto agree that no Party will make a ratable allocation election under Treasury Regulations Sections 1.1502-76(b)(2)(ii)-(iii ) and 1.706-4(a)(3) or any other similar provision of state or local law, and all allocations between taxable periods shall be made on a “closing
of the books method.” 
 3.2 Holiday Recapture. Exhibit F sets forth certain Tax Holidays applicable to Realigned DuPont
Entities and the applicable requirements for avoiding recapture of any previously received benefits under such Tax Holidays for pre-Realignment taxable periods (or portions thereof). Exhibit G sets
forth certain Tax Holidays applicable to Realigned Dow Entities and the applicable requirements for avoiding recapture of any previously received benefits under such Tax Holidays for pre-Realignment taxable
periods (or portions thereof). In the case of Tax Holidays listed on Exhibit F, following the Dow Distribution, Dow shall, and shall cause its Subsidiaries to, use commercially reasonable efforts to comply with the applicable requirements
listed on Exhibit F. In the case of Tax Holidays listed on Exhibit G, (i) prior to the AgCo Distribution, DowDuPont shall, and shall cause its Subsidiaries to, and (ii) following the AgCo Distribution (A) AgCo in the
case of an AgCo Entity that is a Realigned Dow Entity, or (B) SpecCo in the case of a SpecCo Entity that is a Realigned Dow Entity, shall, and shall cause their respective Subsidiaries to, use their commercially reasonable efforts to comply
with the applicable requirements listed on Exhibit G. Taxes imposed as a result of a breach of the covenants contained in this Section 3.2 shall be allocated to the Party breaching such covenant. 

3.3 Tax Attributes; E&P. 

(a) As soon as reasonably practicable after the Dow Distribution Date, the Tax Officers of Dow, DowDuPont and AgCo shall cooperate in good
faith to determine the allocation of Tax Attributes between the Dow Entities and the DowDuPont Entities, and, as soon as reasonably practicable after the AgCo Distribution Date, the Tax Officers of AgCo and SpecCo shall cooperate in good faith to
determine the allocation of Tax Attributes between the AgCo Entities and the SpecCo Entities, in each case, in accordance with the Code and Treasury Regulations (including, for purposes of this Section 3.3(a), any proposed income tax
regulations to the extent no final or temporary income tax regulations have been issued that supersede such proposed regulations) including (i) the principles of the “percentage method” described in Treasury Regulation Section 1.1502-33(d)(3) shall apply, using one hundred percent (100%) as the fixed percentage (the “Percentage Method”) (ii) in the case of Tax Attributes other than 

  
 30 

 earnings and profits, Treasury Regulations Sections 1.46-1, 1.1502-4, 1.1502-9(c), 1.1502-21, 1.1502-21T,
1.1502-22, 1.1502-24, 1.1502-79 and, if applicable, 1.1502-79A (and any applicable state,
local and foreign Tax laws), and (iii) in the case of earnings and profits, in accordance with Code Section 312(h) and Treasury Regulations Section 1.312-10(a) and
1.1502-33(e). The operation of the provisions of this Section 3.3(a), Section 2.2 and Section 2.5 are further illustrated by the examples attached as Exhibit H
(collectively, the “Methodology and Examples”). Section 2.2, Section 2.5 and this Section 3.3(a) shall be interpreted consistently with the Methodology and Examples, and the parties intend the
Methodology and Examples to form a part of this Agreement. Any dispute that the Tax Officers are unable to resolve in respect of such determination shall be referred to a senior executive of each Party involved in the dispute who shall cooperate in
good faith to resolve such dispute. Any dispute that such senior executives are unable to resolve shall be resolved by the Dispute Resolution Firm pursuant to Section 8.1. Unless otherwise agreed by the Parties, any disputes under this
Section 3.3(a) shall be conclusively resolved by the Dispute Resolution Firm prior to (i) the due date for the U.S. federal consolidated income tax return of DowDuPont for the taxable year that includes the Dow Distribution, in the
case of disputes between Dow and DowDuPont, and (ii) the due date for the U.S. federal consolidated income tax return of DowDuPont for the taxable year that includes the AgCo Distribution, in the case of disputes between AgCo and SpecCo. The
Parties hereby agree to compute all Taxes for any taxable period after the Dow Distribution Date or the AgCo Distribution Date, as applicable, consistently with the determination of the allocation of Tax Attributes pursuant to this
Section 3.3(a) unless otherwise required by a Final Determination. 
 (b) To the extent that the amount of any Tax Attribute is
later reduced or increased by a Tax Authority or Tax Proceeding, such reduction or increase shall be allocated to the Party to which such Tax Attribute would have been allocated pursuant to Section 3.3(a). 

3.4 Section 336(e) Election. Pursuant to Treasury Regulation Sections 1.336-2(h)(1) and 1.336-2(j), in connection with the Dow Distribution, DowDuPont shall make a timely protective election under Section 336(e) of the Code and the Treasury Regulations issued thereunder for Dow and each of its
domestic Subsidiaries for which such election is available (a “Section 336(e) Election”). The Parties shall cooperate in making such Section 336(e) Election, including filing any statements, amending any Tax Returns or
taking such other action reasonably necessary to carry out the Section 336(e) Election. If, pursuant to a Final Determination, Section 336(e) applies with respect to the Dow Distribution, Dow shall provide DowDuPont or SpecCo, as
applicable, with a proposed determination of the “Aggregate Deemed Asset Disposition Price” and the “Adjusted Grossed-Up Basis” (each as defined under applicable Treasury Regulations) and
the allocation of such Aggregate Deemed Asset Disposition Price and Adjusted Grossed-Up Basis among the disposition date assets of Dow and its Subsidiaries in accordance with the applicable provisions of
Section 336(e) of the Code and applicable Treasury Regulations (the “Section 336(e) Allocation Statement”). Within thirty (30) days after receipt of the Section 336(e) Allocation Statement, DowDuPont or SpecCo,
as applicable, may provide comments to Dow, to the Section 336(e) Allocation Statement and Dow shall accept any such reasonable comments. In such case, no DowDuPont Entity, Dow Entity, AgCo Entity or SpecCo Entity shall take any position
inconsistent with the Section 336(e) Election including the Section 336(e) Allocation Statement.

Return, the Preparing Party shall compute the amount of Tax required to be paid to the applicable Taxing Authority with respect to such Tax Return on such Payment Date, and the portion of such Tax (if any) for which any Reviewing Party is
responsible pursuant to this Agreement. Each Reviewing Party shall pay to the Preparing Party an amount equal to any Taxes to be paid on such Payment Date for which the Reviewing Party is responsible pursuant to this Agreement. 

  
 33 

 (b) Adjustments to Initial Payment. If either a Tax Proceeding or an amendment to any
Tax Return, results in an adjustment to any amounts payable pursuant to this Agreement (an “Adjustment”), then, (i) the Party filing the amended Tax Return or controlling the Tax Proceeding shall promptly notify the other
relevant Parties in writing regarding the Adjustment to the extent they are otherwise unaware of the Adjustment, and (ii) the relevant amounts previously paid under this Agreement shall be recalculated and a
true-up payment shall be made for the difference between the recalculated amount and the amount previously paid or calculated to be paid, at the time or times provided in the next two sentences. No later than
sixty (60) days following the close of the applicable calendar year, any Adjustments occurring during the applicable calendar year shall be netted between any two Parties, and any Party with a net payable after calculating offsetting
Adjustments to another Party (a “Net Payable”) shall pay the amount of such Net Payable to the Party to which the Net Payable is owed. Notwithstanding the above, if, at any point during the calendar year, the amount of a
Party’s Net Payable exceeds ten million dollars ($10,000,000.00), the Party shall pay such Net Payable, within ninety (90) days of receipt of a written demand by the Party to which the Net Payable is owed. 

4.3 Payment Amount. The amount of any payment pursuant to this Agreement shall (i) be reduced by the amount of any reduction in
Taxes for which the Payee Party is responsible under this Agreement actually realized as a result of the event giving rise to the payment by the end of the taxable year in which the payment is made, and (ii) be increased if and to the extent
necessary to ensure that, after all required Taxes on the payment are paid (including Taxes attributable to any increases in the payment under this Section 4.3), the Payee Party receives the amount it would have received if the payment
was not taxable or did not result in an increase in Taxes. 
 4.4 Characterization of Payments and Certain Transactions. 

(a) To the extent permitted by applicable Law, unless otherwise required by a Final Determination, this Agreement, or as otherwise agreed to
among the Parties (including as may be agreed in any Continuing Arrangements among affiliates of the Parties), for U.S. federal Tax purposes, any payment made pursuant to this Agreement (other than payments of interest) shall be treated as follows:

 (i) to the extent the Paying Party’s Subsidiary or assets and the Payee Party’s Subsidiary or assets to which the liability for
payment relates were separated in a tax-free distribution for U.S. federal Tax purposes, such payment shall be treated as a tax-free contribution or tax-free distribution, as applicable, with respect to the stock of the Paying Party or its relevant Subsidiary, or the Payee Party or its relevant Subsidiary, as applicable, occurring immediately prior to the
relevant transaction in the Internal Reorganization, Dow Contribution or AgCo Contribution, as applicable; and 

  
 34 

 (ii) to the extent the Paying Party’s Subsidiary or assets and the Payee Party’s
Subsidiary or assets to which the liability for payment relates were separated in a taxable transaction for U.S. federal Tax purposes, such payment shall be treated as an adjustment to the price or amount, as applicable, of the relevant transaction
in the Internal Reorganization, Dow Contribution or AgCo Contribution, as applicable. 
 Payments of interest shall be treated as deductible
by the Paying Party or its relevant Subsidiary and as income to the Payee Party or its relevant Subsidiary, as permitted and applicable. In the case of each of the foregoing, no Party shall take a position inconsistent with such treatment. In the
event that a Taxing Authority asserts that a Party’s treatment of a payment pursuant to this Agreement should be other than as set forth in this Section 4.4(a), such Party shall use its commercially reasonable efforts to contest
such challenge. 
 (b) To the extent a Party or its Subsidiary is required to engage in any transaction described in clauses (i)(C) or
clause (ii) of the definitions of Dow Realignment Transactions or DuPont Realignment Transactions, then unless otherwise required by a Final Determination, the Parties shall treat such transaction as “relating back” to a relevant tax-free transaction.    No Party shall take a position inconsistent with such treatment, and in the event that a Taxing Authority asserts that a Party’s treatment should be other than as
set forth in this Section 4.4(b), such Party shall use its commercially reasonable efforts to contest such challenge. 
 4.5
Further Allocation of Obligations. 
 (a) Obligations of DowDuPont. Following the AgCo Distribution, AgCo shall be allocated
and shall be responsible for all liabilities and obligations of DowDuPont under this Agreement that are Agriculture Attributable Obligations and SpecCo shall be allocated and responsible for all liabilities and obligations of DowDuPont under this
Agreement that are Specialties Attributable Obligations. In the absence of any agreement between AgCo and DowDuPont as to the Agriculture Attributable Obligations prior to the AgCo Distribution Date, SpecCo shall be allocated and shall be
responsible for all liabilities and obligations of DowDuPont under this Agreement. 
 (b) Obligations of Dow. If as of the time of
the AgCo Distribution, Dow shall have an outstanding obligation to indemnify DowDuPont pursuant to this Agreement for any Tax liability that DowDuPont has paid, then Dow shall, subject to the next sentence, be liable to SpecCo for the full amount of
such outstanding obligation. If SpecCo and AgCo jointly agree that a particular outstanding obligation is properly owed to AgCo, and so inform Dow in writing, Dow shall be liable to AgCo for the full amount of such obligation. SpecCo and AgCo shall
each inform the other, in writing, upon receipt of any payment in satisfaction of a liability described in this Section 4.5(b). 

4.6 Procedures and Limitations Relating to Indemnification Payments for Intercompany Accounts. 

(a) Each Party shall, and shall cause its Subsidiaries to, use reasonable efforts to mitigate any Taxes described in clauses (iii) of the
definitions of Dow Realignment Taxes and DuPont Realignment Taxes (other than Taxes related to the Identified Selected Dow Intercompany Accounts which shall be subject to Section 4.6(f)) if another Party would be required to indemnify
that Party for any such Taxes pursuant to Section 4.1 of this Agreement. 

  
 35 

 (b) No later than sixty (60) days following the filing of the U.S. federal income Tax
Return for any Party, the Party shall calculate the amount of any Taxes described in clauses (ii)-(iii) of the definitions of Dow Realignment Taxes and DuPont Realignment Taxes if another Party would be required to indemnity that Party for any such
Taxes pursuant to Section 4.1 of this Agreement (such indemnifiable Taxes, “Intercompany Account Taxes”) for which it has a claim against another Party for the period covered by such Tax Return (“the Intercompany Indemnity
Amount”). The Payee Party shall prepare a statement (the “Intercompany Indemnity Statement”) detailing the Payee Party’s calculation of the Intercompany Indemnity Amount for which the Payee Party is seeking
payment and deliver the Intercompany Indemnity Statement to the Paying Party. The Intercompany Indemnity Statement shall include sufficient supporting detail regarding each element of Intercompany Indemnity Amount to permit the Paying Party to
review and consider the Intercompany Indemnity Statement. The Paying Party shall have sixty (60) days to review and consider the Intercompany Indemnity Statement and the Payee Party shall make its employees and representatives available to
answer any question of the Paying Party (or its advisors) regarding the Intercompany Indemnity Amount during such period. Following such sixty (60) day period, any outstanding dispute regarding the Intercompany Indemnity Amount shall be
resolved by the Dispute Resolution Firm in accordance with Section 8.1. 
 (c) Ten (10) days following the Paying Party’s
review and approval or, in the event of any dispute regarding the Intercompany Indemnity Amount, the Dispute Resolution Firm’s resolution of the dispute, the Paying Party shall pay the amount of the Intercompany Account Taxes agreed to by the
applicable Parties or, in the event of any dispute regarding the Intercompany Indemnity Amount, determined by the Dispute Resolution Firm in respect of the period covered by the applicable Tax Return. 

(d) The amount of any Intercompany Account Taxes described in clauses (ii) – (iii) of the definitions of Dow Realignment Taxes and DuPont
Realignment Taxes in respect of any particular Historical Dow Selected Intercompany Account or Historical DuPont Selected Intercompany Account shall be reduced by any cash tax savings resulting for a taxable year ending on or prior to
December 31, 2020, by the Party otherwise entitled to indemnification for such Intercompany Account Taxes as a result of the utilization of a U.S. federal foreign tax credit under Section 901 generated by reason of transactions undertaken,
on or prior to December 31, 2020, to settle, by means of cash payments, a dividend, capital contribution, or a combination of the foregoing, such Historical Dow Selected Intercompany Account or Historical DuPont Selected Intercompany Account
(with such savings computed on a “with and without” basis). 
 (e) Cap 

(i) The aggregate amount described in clause (ii) of the definition of Dow Realignment Taxes for which Dow is required to indemnify the
Parties (other than Dow) hereunder shall not exceed the Dow Intercompany Indemnity Cap, and, in the event that such sum would otherwise, absent application of this Section 4.6(d), exceed the Dow Intercompany Indemnity Cap, the amounts of such
Taxes for which AgCo and SpecCo shall be entitled to indemnification from Dow pursuant to this Agreement shall be reduced proportionately, so that the aggregate sum of such Taxes for which AgCo and SpecCo are entitled to indemnification pursuant to
this Agreement equals the Dow Intercompany Indemnity Cap. 

  
 36 

 (ii) The aggregate amount described in clause (ii) of the definition of DuPont
Realignment Taxes for which the Parties (other than Dow) are required to indemnify Dow hereunder shall not exceed the DuPont Intercompany Indemnity Cap, and, in the event that such sum would otherwise, absent application of this Section 4.6(d),
exceed the DuPont Intercompany Indemnity Cap, the amounts of such Taxes for which Dow shall be entitled to indemnification pursuant to this Agreement from each of AgCo and SpecCo shall be reduced proportionately, so that the aggregate sum of such
Taxes for which Dow is entitled to indemnification pursuant to this Agreement equals the DuPont Intercompany Indemnity Cap. 
 (f)
Identified Selected Dow Intercompany Accounts. The Parties shall reasonably cooperate, in good faith, to determine a mutually agreeable manner to eliminate, settle, or otherwise unwind the Identified Selected Dow Intercompany Accounts in a
manner that minimizes, to the extent possible, the Taxes incurred as a result of the settlement or unwind of the Identified Selected Dow Intercompany Accounts. Notwithstanding the foregoing, provided that such Party uses reasonable efforts to
mitigate any such Taxes, the obligations of this Section 4.6(f), and/or the failure to arrive at any mutually agreeable elimination, settlement or unwind of the Identified Selected Dow Intercompany Accounts shall in no way limit any Party’s
right to indemnification hereunder for any Dow Realignment Taxes related to maintaining or settling the Identified Selected Dow Intercompany Accounts. 

(g) Notice Requirements. No Party shall be entitled to indemnification for any Taxes or amounts described in clauses (ii)-(iii) of the
definitions of DuPont Realignment Taxes and Dow Realignment Taxes unless such Party has provided notice (in the manner required under this Agreement) on or prior to December 31, 2020, to the Parties otherwise required to indemnify for such
Taxes hereunder, that such Taxes or amounts may be required to be indemnified hereunder; provided, however, that this Section 4.6(f) shall not apply to Taxes or amounts related to the Identified Selected Dow Intercompany Accounts. 

4.7 Cap on Repatriation Taxes. 

(a) The aggregate amount described in the definition of AgCo Dow Cash Repatriation Taxes and SpecCo Dow Cash Repatriation Taxes for which Dow
is required to indemnify the Parties (other than Dow) hereunder shall not exceed $10,000,000.00, and, in the event that such sum would otherwise, absent application of this Section 4.7(a), exceed $10,000,000.00, the amounts of such Taxes
for which AgCo and SpecCo shall be entitled to indemnification from Dow pursuant to this Agreement shall be reduced proportionately, so that the aggregate sum of such Taxes for which AgCo and SpecCo are entitled to indemnification pursuant to this
Agreement equals $10,000,000.00. 
 (b) The aggregate amount described in the definition of MatCo DuPont Ag Cash Repatriation Taxes and
MatCo DuPont Spec Cash Repatriation Taxes for which the Parties (other than Dow) are required to indemnify Dow hereunder shall not exceed $10,000,000.00, and, in the event that such sum would otherwise, absent application of this
Section 4.7(b), exceed $10,000,000.00, the amounts of such Taxes for which Dow shall be entitled to indemnification pursuant to this Agreement from each of AgCo and SpecCo shall be reduced proportionately, so that the aggregate sum of
such Taxes for which Dow is entitled to indemnification pursuant to this Agreement equals $10,000,000.00.

 ARTICLE V 

COOPERATION AND RECORD RETENTION 

5.1 General Cooperation. The Parties shall each cooperate fully (and each shall cause its respective Subsidiaries to cooperate fully)
with all reasonable requests in writing from another Party hereto, or from an agent, representative or advisor to such Party, in connection with the preparation and filing of Tax Returns, claims for Refunds, Tax Proceedings, and calculations of
amounts required to be paid pursuant to this Agreement, in each case, related or attributable to or arising in connection with Taxes of any of the Parties or their respective Subsidiaries covered by this Agreement and the establishment of any
reserve required in connection with any financial reporting (a “Tax Matter”). Such cooperation shall include the provision of any information reasonably necessary or helpful in connection with a Tax Matter and shall include, without
limitation: 
 (i) the provision of any Tax Returns of the Parties and their respective Subsidiaries, books, records (including information
regarding ownership and Tax basis of property), documentation and other information relating to such Tax Returns, including accompanying schedules, related work papers, and documents relating to rulings or other determinations by Tax Authority; 

(ii) the execution of any document (including any power of attorney) in connection with any Tax Proceedings of any of the Parties or their
respective Subsidiaries which another Party is entitled to control pursuant to Section 6.2; 
 (iii) the use of the
Party’s reasonable best efforts to obtain any documentation in connection with a Tax Matter; 
 (iv) the use of the Party’s
reasonable best efforts to obtain any Tax Returns (including accompanying schedules, related work papers, and documents), documents, books, records or other information in connection with the filing of any Tax Returns of any of the Parties or their
Subsidiaries; and 
 (v) each Party shall make its employees, advisors, and facilities available on a reasonable and mutually convenient
basis in connection with the foregoing matters. 
 (b) Notwithstanding anything in this Agreement to the contrary, no Party shall be
required to provide the other Party or any of such other Party’s Subsidiaries access to or copies of information, documents or personnel if such action could reasonably be expected to result in the waiver of any Privilege. In the event that
either Party determines that the provision of any information or documents to the other Party or any of such other Party’s Subsidiaries could be commercially detrimental, violate any law or agreement or waive any Privilege, the Parties shall
use commercially reasonable efforts to permit compliance with its obligations hereunder in a manner that avoids any such harm or consequence. 

  
 38 

 (c) The Parties shall perform all actions required or permitted under this Agreement in good
faith. If one Party requests the cooperation of the other Party pursuant to this Section 5.1 or any other provision of this Agreement, except as otherwise expressly provided in this Agreement, the requesting Party shall reimburse such
other Party for all reasonable, third-party, out-of-pocket costs and expenses incurred by such other Party in complying with the requesting Party’s request. 

5.2 Retention of Records. Each Party shall retain or cause to be retained all Tax Returns, schedules and work papers, and all material
records or other documents relating thereto in their possession, in each case that relate to a Tax period, until the later of the ten-year anniversary of the filing of the relevant Tax Return or, upon the
written request of any other Party, for a reasonable time thereafter (the “Retention Period”). Before any disposition or destruction of such materials following the Retention Period, the Party retaining such materials shall give the
other Parties ninety (90) days prior written notice of any such proposed disposition or destruction and the other Parties shall have the right, in their sole discretion and at their own expense, to take possession of such materials. 

ARTICLE VI 
 REFUNDS AND AUDITS

 6.1 Refunds and Credits. 

(a) Tax Refunds. 
 (i)
Except as provided in Section 6.1(a)(ii) and Section 6.1(a)(iii), each Party shall be entitled to all Refunds of Taxes for which such Party is responsible pursuant to this Agreement. For the avoidance of doubt, to the extent
that a particular Refund of Taxes may be allocable to any Tax period with respect to which the Parties may share responsibility pursuant to this Agreement, the portion of such Refund to which each Party will be entitled shall be determined by
comparing the amount of payments made by a Party (or any of its Subsidiaries at such time) to a Tax Authority or to the other Party (and reduced by the amount of payments received from the other Party) pursuant to this Agreement with the Tax
liability of such Party, taking into account the facts as utilized for purposes of claiming such Refund. If a Party (or any of its Subsidiaries) receives a Refund to which the other Party is entitled pursuant to this Agreement, such Party shall pay
the amount to which such other Party is entitled within sixty (60) days after the receipt of the Refund. For purposes of this Section 6.1(a)(i), TDCC and its Subsidiaries as of any time shall be treated as Subsidiaries of Dow as of
such time. 
 (ii) The Party directly or indirectly owning a Realigned Entity following Realignment (the “Controlling
Party”) shall be entitled to 50% of Refunds of Taxes (net of applicable third-part costs paid by the Controlling Party to obtain such Refunds) paid in respect of such Realigned Entity for taxable periods (or portions thereof) ending on or
before the Realignment Date in respect of such Realigned Entity, and which Refunds reduce Taxes in a taxable period (or portion thereof) ending on or before the Realignment Date (including by way of a payment made from the relevant Tax Authority to
the relevant Realigned Entity with respect to such taxable period or portion thereof) with respect to such Realigned Entity, to which another Party (the “Refund Party”) would otherwise be entitled under Section 6.1(a)(i)
if both (A) the Refund Party provides its written consent for the Controlling Party to pursue such Refund and (B) such Refund is obtained through the material efforts of the Controlling Party or its Subsidiary. 

  
 39 

 (iii) The Controlling Party shall be entitled to 100% of Refunds of Taxes paid in respect
of its Realigned Entity for taxable periods (or portions thereof) ending on or before the Realignment Date in respect of such Realigned Entity, and which Refunds are of a type that can only be obtained through a reduction of Taxes in a taxable
period (or portion thereof) ending after the Realignment Date (including by way of a payment made from the relevant Tax Authority to the relevant Realigned Entity in respect of any payments made by such Realigned Entity with respect to such taxable
period or portion thereof) with respect to such Realigned Entity, to which the Refund Party would otherwise be entitled under Section 6.1(a)(i) if (A) the Refund Party, TDCC or DuPont, as applicable, did not reflect the Refund as an
asset or reduction of a liability on its audited consolidated financial statements prior to Realignment and the Refund relates to periods included in such financial statements or (B) such Refund is set forth on Exhibit I. 

(b) In the event of an adjustment relating to Taxes for which one Party is responsible pursuant to this Agreement which would have given rise
to a Refund but for an offset against the Taxes for which another Party is or may be responsible pursuant to this Agreement, then such amount shall be considered as resulting in an adjustment in such amount for purposes of Section 4.2(b)
and shall be treated accordingly. 
 (c) Notwithstanding Section 6.1(a), to the extent that a Party (or any of its Subsidiaries)
applies or causes to be applied an overpayment of Taxes as a credit toward or a reduction in Taxes otherwise payable (or a Tax Authority requires such application in lieu of a Refund) and such overpayment of Taxes, if received as a Refund, would
have been payable by such Party to the other Party pursuant to this Section 6.1, such Party shall pay such amount to the other Party no later than the Due Date of the Tax Return for which such overpayment is applied to reduce Taxes
otherwise payable. 
 (d) To the extent that the amount of any Refund under this Section 6.1 is later reduced by a Tax Authority
or in a Tax Proceeding, such reduction shall be allocated to the Party to which such Refund was allocated pursuant to this Section 6.1 and shall be considered an adjustment for purposes of Section 4.2(b) and shall be treated
accordingly. 
 6.2 Audits and Proceedings. 

(a) If a Payee Party or any of its Subsidiaries receives any notice, letter, correspondence, claim or decree from any Tax Authority (a
“Tax Notice”) and, upon receipt of such Tax Notice, believes it has suffered or potentially could suffer any Tax liability for which it is expected to be indemnified pursuant to this Agreement, the Payee Party shall promptly deliver
such Tax Notice to the Paying Party but in any event within ten (10) days (or such shorter period as may be necessary to permit the Paying Party to timely consider and respond to such Tax Notice) of the receipt of such Tax Notice;
provided, however, that the failure of the Payee Party to provide the Tax Notice to the Paying Party shall not affect the indemnification rights of the Payee Party pursuant to this Agreement, except to the extent that the Paying Party
is prejudiced by the Payee Party’s failure to deliver such Tax Notice. Subject to Section 6.2(c) below, the 

  
 40 

 Paying Party shall have the right to (i) handle, defend, conduct and control, at its own expense
(including, for the avoidance of doubt, by funding any payments required to be made to a Taxing Authority in order to conduct a Tax Proceeding in a manner of its choosing), any aspect of any Tax Proceeding to the extent that it relates solely to
Taxes for which it is responsible pursuant to this Agreement, and (ii) compromise or settle any such aspect of such Tax Proceeding. The Paying Party shall (A) keep the Payee Party informed in a timely manner of all actions proposed to be
taken by the Paying Party with respect to a Tax Proceeding it controls, (B) permit the Payee Party to participate in all proceedings with respect to such Tax Proceeding, (C) not settle any such Tax Proceeding without the prior written
consent of the Payee Party, as the case may be, which consent shall not be unreasonably withheld, conditioned or delayed and (D) use reasonable best efforts to ensure that the manner defense, conduct, control, of any Tax Proceeding does not
create material business disruptions for the Payee Party or any Affiliate (for example, by contesting a Tax prior to payment in a manner that prevents the Payee Party from receiving tax clearance certificates or other documentation from an
applicable Taxing Authority that are necessary to conduct its operations or avoid the imposition or collection of material Taxes on an ongoing basis). Any Tax liability resulting from a Final Determination shall be considered an adjustment for
purposes of Section 4.2(b) and shall be treated accordingly. 
 (b) Subject to Sections 6.2(a) and (c), 

(i) Subject to the next sentence, (A) Dow shall have the sole right to handle, defend, conduct and control any Tax Proceeding related to
the U.S. federal consolidated income Tax Returns of TDCC relating to all taxable periods ending on or before December 31, 2016, (B) DowDuPont, prior to the AgCo Distribution, and SpecCo, following the AgCo Distribution, shall have the sole
right to handle, defend, conduct and control any Tax Proceeding related to the U.S. federal consolidated income Tax Returns of DuPont relating to all taxable periods ending on or before August 31, 2017, (C) Dow, DowDuPont and SpecCo shall
jointly handle, defend, conduct and control any Tax Proceeding related to the U.S. federal consolidated income Tax Return of DowDuPont relating to the taxable period ending on December 31, 2017, and (D) DowDuPont, prior to the AgCo
Distribution, and SpecCo, following the AgCo Distribution, shall have the right to handle, defend, conduct and control any Tax Proceeding related to the U.S. federal consolidated income Tax Returns of DowDuPont or SpecCo relating to a taxable period
ending after December 31, 2017. The principles of the foregoing sentence shall also apply for purposes of determining the control of Tax Proceedings with respect to U.S. state or local consolidated, combined, unitary or affiliated Tax Returns.
The party controlling any Tax Proceeding described in the foregoing clauses shall (1) keep the other Parties informed in a timely manner of all actions proposed to be taken with respect to a Tax Proceeding it controls, (2) permit the other
Parties to participate in all proceedings with respect to such Tax Proceeding, and (3) not settle any such Tax Proceeding without the prior written consent of the other Parties, as the case may be, which consent shall not be unreasonably
withheld, conditioned or delayed. 
 (c) Notwithstanding Sections 6.2(a) and (b), 

(i) the Parties shall have the right to jointly control any Tax Proceeding that relates to the
Tax-Free Status of the Transactions; 

  
 41 

 (ii) if more than one Party could be responsible under this Agreement for any Taxes
resulting from a resolution of a particular issue involved in a Tax Proceeding, then all such Parties shall have the right to jointly control the Tax Proceeding to the extent relating to the issue; 

(iii) if a Tax Proceeding involves an issue that recurs in subsequent taxable periods and one or more Parties that are not responsible under
this Agreement for the Taxes directly involved in the Tax Proceeding would be bound by, or could reasonably be prejudiced with respect to the issue by, the outcome of the Tax Proceeding in subsequent taxable periods for which the Party or Parties
would be responsible under this Agreement, then such Parties and the Party directly responsible for the Taxes at issue in the Tax Proceeding shall have the right to jointly control such Tax Proceeding; and 

(iv) in each of the above cases, no Party shall compromise or settle any Tax Proceeding without the consent of the other Party or Parties
entitled to control such Tax Proceeding (such consent not to be unreasonably withheld, conditioned or delayed). 
 ARTICLE VII 

TAX-FREE STATUS OF THE TRANSACTIONS 

7.1 Covenants. 
 (a) No
Party shall take, or permit any of its Subsidiaries to take, any action in violation of the restrictions set forth on Exhibit E. 

(b) During the Restricted Period, each Party: 

(i) shall continue or cause to be continued, taking into account Section 355(b)(3) of the Code, the active conduct of the business on
which it relied for purposes of satisfying the requirements of Section 355(b) of the Code; 
 (ii) shall not dissolve or liquidate
itself (including any action that is a liquidation for federal income tax purposes); 
 (iii) shall not (A) enter into, permit,
approve of or fail to take any action within its control to prevent any transactions relating to its stock, or rights to acquire its stock, including any redemption or other repurchase (directly or through a Subsidiary), other than
(1) issuances of stock that satisfy the requirements of Safe Harbor VIII (relating to acquisitions in connection with a Person’s performance of services) or Safe Harbor IX (relating to acquisitions by a retirement plan of an employer) of
Treasury Regulations Section 1.355-7(d), or (2) share repurchases that both (I) satisfy the requirements of Section 4.05(1)(b) of Revenue Procedure
96-30, 1996-1 C.B. 696 (as in effect prior to the release of Revenue Procedure 2003-48,
2003-2 C.B. 86) and (II) constitute Share Repurchases, (B) amend its certificate of incorporation (or other organizational documents), or take any other action, whether through a stockholder vote or
otherwise, affecting the relative voting rights of its capital stock (including through the conversion of any capital stock into another class of capital stock), or (C) merge or consolidate with any other Person unless the applicable Party is
the surviving corporation in any such merger or consolidation; and 

  
 42 

 (iv) shall not, and shall not permit any member of its “separate affiliated group”
(within the meaning of Section 355(b)(3)(B) of the Code), to sell, transfer, or otherwise dispose of or agree to, sell, transfer or otherwise dispose (including in any transaction treated for federal income tax purposes as a sale, transfer or
disposition) of assets (including, any shares of capital stock of a Subsidiary) that, in the aggregate, constitute more than twenty-five percent (25%) of the consolidated gross assets of its “separate affiliated group.” The foregoing
sentence shall not apply to (A) sales, transfers, or dispositions of assets in the ordinary course of business, (B) any cash paid to acquire assets from an unrelated Person in an arm’s-length
transaction, (C) any assets transferred to a Person that is disregarded as an entity separate from the transferor for federal income tax purposes, (D) any mandatory or optional repayment (or pre-payment) of any indebtedness of any Party or
any member of its “separate affiliated group” or (E) the AgCo Distribution or any DuPont Realignment Transaction undertaken by DowDuPont, DuPont or any of its Subsidiaries. For purposes of this Section 7.1(b)(iv), a merger
of a Party or one of its Subsidiaries with and into any Person that is not a wholly-owned Subsidiary of such Party shall constitute a disposition of all of the assets of such Party or such Subsidiary. 

(c) Notwithstanding the restrictions imposed by Section 7.1, a Party may proceed with any of the actions or transactions described
therein, if (i) such Party shall first have requested and obtained from the other Parties consent to obtain a Ruling in accordance with Section 7.2 and such Party shall have received such Ruling in form and substance reasonably
satisfactory to the other Parties, (ii) such Party shall have provided to the other Parties an Unqualified Tax Opinion in form and substance reasonably satisfactory to such other Parties, or (iii) the other Parties shall have waived in
writing the requirement to obtain such ruling or opinion. For the avoidance of doubt, the presence of a Ruling, an Unqualified Tax Opinion or a waiver from a Party shall not relieve any Party from indemnification obligations otherwise present under
this Agreement. In determining whether a ruling or opinion is satisfactory, a Party may consider, among other factors, the appropriateness of any underlying assumptions, representations or covenants used as a basis for the ruling or opinion and the
views on the substantive merits. 
 (d) Tax Reporting. Unless there is a Final Determination to the contrary, each Party covenants
and agrees that it will not take, and will cause its respective Subsidiaries to refrain from taking, any position on any Tax Return that is inconsistent with the Tax-Free Status of the Transactions. 

7.2 Procedures Regarding Opinions and Rulings. If a Party notifies the other Parties that it desires to take one of the actions
described in Section 7.1 (a “Proposed Action” and such Party a “Notifying Party”), the other Parties shall cooperate with the Notifying Party and use their reasonable best efforts to seek to obtain a
Ruling or an Unqualified Tax Opinion for the purpose of permitting the Notifying Party to take the Proposed Action unless the other Parties shall have waived the requirement to obtain such ruling or opinion. If such a ruling is to be sought, the
Notifying Party shall apply for such ruling and the Notifying Party and the other Parties shall jointly control the process of obtaining such ruling. The other Parties shall take any and all actions reasonably requested by the Notifying Party in
connection with obtaining such 

  
 43 

 ruling or opinion (including by making any representation or reasonable covenant or providing any materials
requested by the IRS or the law firm issuing such opinion); provided, that the other Parties shall not be required to make (or cause any of their respective Subsidiaries to make) any representation or covenant that is untrue or inconsistent
with historical facts, or as to future matters or events over which it has no control. In no event shall the Notifying Party be permitted to file any ruling request under this Section 7.2 unless the other Parties have approved such
ruling request (such approval not to be unreasonably withheld, conditioned or delayed). The Notifying Party shall reimburse each of the other Parties for all reasonable costs and expenses incurred by the Party or any of its Subsidiaries in obtaining
or seeking to obtain a Ruling or Unqualified Tax Opinion requested by the Notifying Party within ten (10) days after receiving an invoice from the other Party therefor. 

7.3 Deferred Items. 
 (a)
Exhibit J sets forth certain Deferred Items of Realigned Dow Entities and the requirements for avoiding triggering, accelerating or otherwise causing such Deferred Items to be included in income (the “Listed Dow Deferred
Items”). Exhibit K sets forth certain Deferred Items of Realigned DuPont Entities and the requirements for avoiding triggering, accelerating, or otherwise causing such Deferred Items to be included in income (the “Listed
DuPont Deferred Items” and, together with the Listed Dow Deferred Items, the “Listed Deferred Items”). Subject to Section 7.3(b), each Party shall, and shall cause its Subsidiaries to, use commercially
reasonable efforts not to trigger, accelerate, or otherwise cause to be included in income any Listed Deferred Item if another Party would be required to indemnify that Party for Taxes attributable to such Listed Deferred Item pursuant to
Section 4.1 of this Agreement. Notwithstanding anything to the contrary in this Agreement, a Party shall not be allocated Taxes attributable to Listed Deferred Items which were triggered, accelerated or otherwise included in income by
actions of another Party in violation of the covenant in the preceding sentence. 
 (b) Each Party shall be considered to have used
commercially reasonable efforts with respect a Listed Deferred Item for purposes of Section 7.3(a) provided it complies with the applicable requirements related to such Deferred Item provided on the relevant Exhibit. 

ARTICLE VIII 
 DISPUTE RESOLUTIONS

 8.1 Dispute Resolution. In the event of any dispute between or among the Parties as to any matter covered by this Agreement, the
Parties to the dispute shall appoint a nationally recognized independent public accounting firm or a nationally recognized law firm, to resolve such dispute (the “Dispute Resolution Firm”). In this regard, the Dispute Resolution
Firm shall make determinations with respect to the disputed items based solely on representations made by the Parties and their respective representatives, and not by independent review, and shall function only as an expert and not as an arbitrator
and shall be required to make a determination in favor of one Party only. The Parties shall require the Dispute Resolution Firm to resolve all disputes no later than sixty (60) days after the submission of such dispute to the Dispute Resolution
Firm, but in no event later than the Due Date for the payment of Taxes or the filing of the applicable Tax Return, if applicable, and agree that all decisions by the Dispute Resolution 

  
 44 

 Firm with respect thereto shall be final and conclusive and binding on the Parties. The Dispute Resolution
Firm shall resolve all disputes in a manner consistent with this Agreement and, to the extent not inconsistent with this Agreement, in a manner consistent with the Past Practices of the Parties in respect of the entities or operations giving rise to
the matter to which the dispute relates, except as otherwise required by applicable law. The Parties to the dispute shall require the Dispute Resolution Firm to render all determinations in writing and to set forth, in reasonable detail, the basis
for such determination. The fees and expenses of the Dispute Resolution Firm shall be borne equally by the Parties to the dispute. 
 8.2
EACH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT
(I) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (II) EACH SUCH PARTY UNDERSTANDS AND
HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (III) EACH SUCH PARTY MAKES THIS WAIVER VOLUNTARILY AND (IV) EACH SUCH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN
THIS SECTION 8.2. 
 ARTICLE IX 

MISCELLANEOUS 
 9.1 Entire

respect to such matters, the terms and conditions of the Tax Matters Agreement shall govern. Notwithstanding anything in this Agreement to the contrary, section 2.09 of the Employee Matters Agreement shall govern in respect of the matters
provided for in that section. 
 9.2 Counterparts. This Agreement may be executed and delivered (including by facsimile or other
means of electronic transmission, such as by electronic mail in “pdf” form) in more than one counterpart, all of which shall be considered one and the same agreement, each of which when executed shall be deemed to be an original, and shall
become effective when one or more such counterparts have been signed by each of the Parties and delivered to each of the Parties. 

  
 45 

 9.3 Survival of Agreement. Except as otherwise contemplated by this Agreement, all
covenants and agreements of the Parties contained in this Agreement shall survive the Effective Time and remain in full force and effect in accordance with their applicable terms. 

9.4 Expenses. Unless otherwise expressly provided in this Agreement, the Separation Agreement or the Ancillary Agreements, each Party
shall bear any and all expenses that arise from their respective obligations under this Agreement. 
 9.5 Changes in Law. Any

 9.7 Waivers. Any provision of this Agreement may be waived, if and only if, such waiver is in writing
and signed by the Party against whom the waiver is to be effective. Notwithstanding the foregoing, no failure to exercise and no delay in exercising, on the part of any Party, any right, remedy, power or privilege hereunder shall operate as a waiver
hereof; nor shall any single or partial exercise of any right, remedy, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege. Any consent required or permitted to
be given by any Party to any other Party under this Agreement shall be in writing and signed by the Party giving such consent and shall be effective only against such Party (and the members of its Group). 

9.8 Amendments. This Agreement may not be modified or amended except by an agreement in writing signed by each of the Parties. 

9.9 Assignment. Except as otherwise provided for in this Agreement, neither this Agreement nor any right, interest or obligation shall
be assignable, in whole or in part, directly or indirectly, by any Party without the prior written consent of the other Parties (not to be unreasonably withheld, conditioned or delayed), and any attempt to assign any rights, interests or obligations
arising under this Agreement without such consent shall be void; except, that a Party 

  
 48 

 may assign this Agreement or any or all of the rights, interests and obligations hereunder in connection
with a merger, reorganization or consolidation transaction in which such Party is a constituent party but not the surviving entity or the sale by such Party of all or substantially all of its assets; provided, that the surviving entity of
such merger, reorganization or consolidation transaction or the transferee of such assets shall assume all the obligations of the relevant Party by operation of law or pursuant to an agreement in writing, reasonably satisfactory to the other
Parties, to be bound by the terms of this Agreement as if named as a “Party” hereto; provided, however, that in the case of each of the preceding clauses, no assignment permitted by this Section 9.9 shall release
the assigning Party from Liability for the full performance of its obligations under this Agreement, unless agreed to in writing by the non-assigning Parties. 

9.10 Successors and Assigns. The provisions of this Agreement and the obligations and rights hereunder shall be binding upon, inure to
the benefit of and be enforceable by (and against) the Parties and their respective successors and permitted transferees and assigns. 

9.11 Certain Termination and Amendment Rights. This Agreement may be terminated at any time prior to the Dow Distribution Date by and
in the sole discretion of the Board without the approval of Dow or AgCo or the stockholders of DowDuPont and, in the event of such termination, no Party shall have any liability of any kind to any other Party or any other Person. The Dow
Distribution may be amended, modified or abandoned at any time prior to the Dow Distribution Date and the AgCo Distribution may be amended, modified or abandoned at any time prior to the AgCo Distribution Date, in each case, by and in the sole
discretion of the Board without the approval of Dow or AgCo or the stockholders of DowDuPont, provided, that no such amendment, modification or abandonment of the AgCo Distribution shall affect any provisions of, or any obligations under,
this Agreement that are for the benefit of Dow or any member of its Group, or prejudice or otherwise adversely affect any rights of Dow or any member of its Group under this Agreement. After the Dow Distribution Date, but prior to the AgCo
Distribution Date, this Agreement may not be terminated or amended except by an agreement in writing signed by DowDuPont and Dow. After the AgCo Distribution Date, this Agreement may not be terminated or amended except by an agreement in writing
signed by the Parties. 
 9.12 Payment Terms 

(a) Except as otherwise expressly provided to the contrary in this Agreement, any amount to be paid or reimbursed by a Party (and/or a member
of such Party’s Group), on the one hand, to another Party (and/or a member of such Party’s respective Group), on the other hand, under this Agreement shall be paid or reimbursed hereunder within thirty (60) days after presentation of
an invoice or a written demand therefor and setting forth, or accompanied by, reasonable documentation or other reasonable explanation supporting such amount. 

(b) Any amount not paid when due pursuant to this Agreement shall bear interest at a rate per annum equal to LIBOR (in effect on the date on
which such payment was due) plus 3% calculated for the actual number of days elapsed, accrued from the date on which such payment was due up to the date of the actual receipt of payment; provided, however, in the event that LIBOR is no
longer commonly accepted by market participants, then an alternative floating rate index that is commonly accepted by market participants, which the Parties shall jointly determine, each acting in good faith. 

  
 49 

 (c) In the event of a dispute or disagreement with respect to all or a portion of any
amounts requested by any Party (and/or a member of such Party’s Group) as being payable, the payor Party shall in no event be entitled to withhold payments for any such amounts (and any such disputed amounts shall be paid in accordance with
this Agreement, subject to the right of the payor Party to dispute such amount following such payment); provided, that in the event that following the resolution of such dispute it is determined that the payee Party (and/or a member of the
payee Party’s Group) was not entitled to all or a portion of the payment made by the payor Party, the payee Party shall repay (or cause to be repaid) such amounts to which it was not entitled, including interest, to the payor Party (or its
designee), which amounts shall bear interest at a rate per annum equal to LIBOR plus 3%, calculated for the actual number of days elapsed, accrued from the date on which such payment was made by the payor Party to the payee Party. 

(d) Without the Consent of the Party receiving any payment under this Agreement specifying otherwise, all payments to be made by the Parties
under this Agreement shall be made in US Dollars. Except as expressly provided herein, any amount which is not expressed in US Dollars shall be converted into US Dollars by using the Bloomberg fixing rate at 5:00 pm New York City Time on the day
before the date the payment is required to be made or, as applicable, on which an invoice is submitted (provided, however, that with regard to any payments in respect of Indemnifiable Losses for payments made to third parties, the date shall be the
day before the relevant payment was made to the third party) or in the Wall Street Journal on such date if not so published on Bloomberg. Except as expressly provided herein, in the event that any indemnification payment required to be made
hereunder may be denominated in a currency other than US Dollars, the amount of such payment shall be converted into US Dollars on the date in which notice of the claim is given to the Party required to make payment hereunder. 

9.13 No Circumvention. The Parties agree not to directly or indirectly take any actions, act in concert with any Person who takes an
action, or cause or allow any member of any such Party’s Group to take any actions (including the failure to take a reasonable action) such that the resulting effect is to materially undermine the effectiveness of any of the provisions of this
Agreement (including adversely affecting the rights or ability of any Party to successfully pursue indemnification or payment hereunder). 

9.14 Subsidiaries. Each of the Parties shall cause to be performed, and hereby guarantees the performance of, all actions, agreements
and obligations set forth herein to be performed by any Subsidiary of such Party or by any entity that becomes a Subsidiary of such Party on and after the Dow Distribution Date or the AgCo Distribution Date, as applicable. 

9.15 Third Party Beneficiaries. This Agreement is solely for the benefit of, and is only enforceable by, the Parties and their
permitted successors and assigns and should not be deemed to confer upon third parties any remedy, benefit, claim, liability, reimbursement, claim of Action or other right of any nature whatsoever, including any rights of employment for any
specified period, in excess of those existing without reference to this Agreement. 
 9.16 Title and Headings. Titles and headings to
sections herein are inserted for the convenience of reference only and are not intended to be a part of or to affect the meaning or interpretation of this Agreement. 

  
 50 

 9.17 Exhibits. The exhibits to this Agreement shall be construed with and as an
integral part of this Agreement to the same extent as if the same had been set forth verbatim herein. Nothing in the exhibits to this Agreement constitutes an admission of any Liability or obligation of any member of the SpecCo Group, the MatCo
Group or the AgCo Group or any of their respective Affiliates to any third party, nor, with respect to any third party, an admission against the interests of any member of the SpecCo Group, the MatCo Group or the AgCo Group or any of their
respective Affiliates. The inclusion of any item or Liability or category of item or Liability on any exhibit hereto is made solely for purposes of allocating potential Liabilities among the Parties and shall not be deemed as or construed to be an
admission that any such Liability exists. 
 9.18 Governing Law. This Agreement and any dispute arising out of, in connection with or
relating to this Agreement shall be governed by and construed in accordance with the Laws of the State of Delaware, without giving effect to the conflicts of laws principles thereof. 

9.19 Neutral Construction. The parties to this Agreement agree that this Agreement was negotiated fairly between them at arms’
length and that the final terms of this Agreement are the product of the parties’ negotiations. Each party represents and warrants that it has sought and received legal counsel of its own choosing with regard to the contents of this Agreement
and the rights and obligations affected hereby. The parties agree that this Agreement shall be deemed to have been jointly and equally drafted by them, and that the provisions of this Agreement therefore shall not be construed against a party on the
grounds that the party drafted or was more responsible for drafting the provision(s). 
 9.20 Specific Performance. The Parties
acknowledge and agree that irreparable harm would occur in the event that the Parties do not perform any provision of this Agreement in accordance with its specific terms or otherwise breach this Agreement and the remedies at law for any breach or
threatened breach of this Agreement, including monetary damages, are inadequate compensation for any such breach. Accordingly, from and after the Effective Time, in the event of any actual or threatened default in, or breach of, any of the terms,
conditions and provisions of this Agreement, the Parties agree that the Party or Parties to this Agreement who are or are to be thereby aggrieved shall, subject and pursuant to the terms of this Article IX (including for the avoidance of doubt,
after compliance with all notice and negotiation provisions herein), have the right to specific performance and injunctive or other equitable relief of its or their rights under this Agreement, in addition to any and all other rights and remedies at
law or in equity, and all such rights and remedies shall be cumulative. The Parties agree that any defense in any action for specific performance that a remedy at law would be adequate is hereby waived, and that any requirements for the securing or
posting of any bond with such remedy are hereby waived. 
 9.21 Severability. In the event any one or more of the provisions
contained in this Agreement should be held invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein and therein shall not in any way be affected or impaired thereby. The
Parties shall endeavor in good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid, legal and enforceable provisions, the economic effect of which comes as close as possible to that of the invalid, illegal or
unenforceable provisions. 

  
 51 

 9.22 No Duplication; No Double Recovery. Nothing in this Agreement is intended to
confer to or impose upon any Party a duplicative right, entitlement, obligation or recovery with respect to any matter arising out of the same facts and circumstances.
