WHEREAS, in furtherance of the foregoing, the Kellanova Board has determined that it is appropriate and desirable to separate the WKKC Business from the Kellanova Business (the “Internal Reorganization”) and, following the Internal Reorganization, make a distribution, on a pro rata basis, to holders of Kellanova Shares on the Record Date of all of the outstanding WKKC Shares owned by ▇▇▇▇▇▇▇▇▇ (the “Distribution”);

WHEREAS, ▇▇▇▇▇▇▇▇▇ will effect certain restructuring transactions described in the Internal Reorganization Step Plan for the purpose of aggregating the WKKC Business in the WKKC Group prior to the Distribution, and, in connection therewith, Kellanova will undertake the Contribution, in exchange for which WKKC (i) shall issue to Kellanova WKKC Shares, pay to Kellanova the WKKC Contribution Payment, and assume certain liabilities related to the WKKC Business, and (ii) may issue to Kellanova certain debt securities of WKKC (the “WKKC Securities”);

WHEREAS, ▇▇▇▇▇▇▇▇▇ intends to effect the Distribution in a transaction that, taken together with the Contribution, is intended to qualify as tax-free to both Kellanova and its shareholders for U.S. federal income tax purposes under Sections 368(a)(1)(D), 355, and 361 of the Code (except with respect to cash received in lieu of a fractional share);

WHEREAS, certain members of the Kellanova Group, on the one hand, and certain members of the WKKC Group, on the other hand, file certain Tax Returns on a consolidated, combined, or unitary basis for certain federal, state, local, and foreign Tax purposes; and

WHEREAS, the Parties desire to (i) provide for the payment of Tax liabilities and entitlement to refunds thereof, allocate responsibility for, and cooperation in, the filing of Tax Returns, and provide for certain other matters relating to Taxes, and (ii) set forth certain covenants and indemnities relating to the preservation of the Tax-Free Status of the Transactions.

If ▇▇▇▇▇▇▇▇▇ determines that a Section 336(e) Election would be beneficial:

(a) ▇▇▇▇▇▇▇▇▇, WKKC, and their respective Affiliates shall cooperate in making the Section 336(e) Election, including by filing any statements, amending any Tax Returns, or taking such other actions as are reasonably necessary to carry out the Section 336(e) Election;

(b) if the Distribution fails to qualify (in whole or in part) for the Tax-Free Status of the Transactions and WKKC or any member of the WKKC Group realizes an increase in Tax basis as a result of the Section 336(e) Election (the “Section 336(e) Tax Basis”), then the Tax Benefit Actually Realized by WKKC and each member of the WKKC Group as a result of the Section 336(e) Tax Basis shall be shared between ▇▇▇▇▇▇▇▇▇ and WKKC in the same proportion as the Taxes giving rise to the Section 336(e) Tax Basis were borne by ▇▇▇▇▇▇▇▇▇ and WKKC (after giving effect to the indemnification obligations in this Agreement); and

12

(c) to the extent the Section 336(e) Election becomes effective, each Party agrees not to take any position (and to cause each of its Affiliates not to take any position) that is inconsistent with the Section 336(e) Election on any Tax Return, in connection with any Tax Contest, or otherwise, except as may be required by a Final Determination.

Section 3.8 Payment of Taxes.

(a) With respect to any Tax Return required to be filed pursuant to this Agreement, the Responsible Party shall remit or cause to be remitted to the applicable Taxing Authority in a timely manner any Taxes due in respect of any such Tax Return.

(b) In the case of any Tax Return for which the Party that is not the Responsible Party is obligated pursuant to this Agreement to pay all or a portion of the Taxes reported as due on such Tax Return, the Responsible Party shall notify the other Party, in writing, of its obligation to pay such Taxes and, in reasonably sufficient detail, its calculation of the amount due by such other Party, and the Party receiving such notice shall pay such amount to the Responsible Party no later than the later of (i) five (5) Business Days prior to the date on which such payment is due, and (ii) fifteen (15) Business Days after the receipt of such notice.

(c) With respect to any estimated Taxes, the Party that is or will be the Responsible Party with respect to any Tax Return that will reflect (or otherwise give credit for) such estimated Taxes shall remit or cause to be remitted to the applicable Taxing Authority in a timely manner any estimated Taxes due. In the case of any estimated Taxes for which the Party that is not the Responsible Party is obligated pursuant to this Agreement to pay all or a portion of the Taxes that will be reported as due on any Tax Return that will reflect (or otherwise give credit for) such estimated Taxes, the Responsible Party shall notify the other Party, in writing, of its obligation to pay such estimated Taxes and, in reasonably sufficient detail, its calculation of the amount due by such other Party and the Party receiving such notice shall pay such amount to the Responsible Party no later than the later of (i) five (5) Business Days prior to the date on which such payment is due, and (ii) fifteen (15) Business Days after the receipt of such notice.

Section 3.9 Amended Returns and Carrybacks.

(a) WKKC shall not, and shall not permit any member of the WKKC Group to, file or allow to be filed any request for an Adjustment for any Pre-Distribution Period without the prior written consent of ▇▇▇▇▇▇▇▇▇, such consent to be exercised in Kellanova’s sole and absolute discretion.

(b) WKKC shall, and shall cause each member of the WKKC Group to, make any available elections to waive the right to carry back any Tax Attribute from a Post-Distribution Period to a Pre-Distribution Period.

(c) WKKC shall not, and shall cause each member of the WKKC Group not to, without the prior written consent of ▇▇▇▇▇▇▇▇▇, make any affirmative election to carry back any Tax Attribute from a Post-Distribution Period to a Pre-Distribution Period, such consent to be exercised in Kellanova’s sole and absolute discretion.

13

(d) Receipt of consent by WKKC or a member of the WKKC Group from Kellanova pursuant to the provisions of this Section 3.9 shall not limit or modify WKKC’s continuing indemnification obligation pursuant to Article V.

Section 3.10 Tax Attributes. Kellanova shall in good faith advise WKKC in writing of the amount (if any) of any Tax Attributes which Kellanova determines, in its sole and absolute discretion, shall be allocated or apportioned to the WKKC Group under applicable Tax Law. WKKC and all members of the WKKC Group shall prepare all Tax Returns in accordance with such written notice. WKKC agrees that it shall not dispute ▇▇▇▇▇▇▇▇▇’s determination of Tax Attributes. For the avoidance of doubt, ▇▇▇▇▇▇▇▇▇ shall not be required in order to comply with this Section 3.10 to create or cause to be created any books and records or reports or other documents based thereon (including, without limitation, any “E&P studies,” “basis studies” or similar determinations) that it does not maintain or prepare in the ordinary course of business.

Section 4.2 Certain Restrictions Relating to the Tax-Free Status of the Transactions.

(a) WKKC, on behalf of itself and all other members of the WKKC Group, hereby covenants and agrees that no member of the WKKC Group will take, fail to take, or cause or permit to be taken (i) any action where such action or failure to act would be inconsistent with or cause to be untrue any statement, information, covenant, or representation in the Tax Materials, or (ii) any action where such action or failure to act constitutes a WKKC Disqualifying Action.

(b) During the Restricted Period, WKKC:

(i) shall (1) maintain its status as a company engaged in the Active Trade or Business for purposes of Section 355(b)(2) of the Code, (2) not engage in any transaction that would cause WKKC to cease to be a company engaged in the Active Trade or Business for purposes of Section 355(b)(2) of the Code, (3) cause each Affiliate of WKKC whose Active Trade or Business is relied upon in the Tax Materials for purposes of qualifying a transaction as tax-free pursuant to Section 355 of the Code to maintain its status as a company engaged in such Active Trade or Business for purposes of Section 355(b)(2) of the Code, (4) not engage in any transaction, or cause or permit an Affiliate of WKKC to engage in any transaction, that would result in an Affiliate of WKKC described in clause (3) to cease to be a company engaged in the relevant Active Trade or Business for purposes of Section 355(b)(2) of the Code, taking into account Section 355(b)(3) of the Code for purposes of clauses (1) through (4), and (5) not dispose of, or cause or permit an Affiliate of WKKC to dispose of, directly or indirectly, any interest in an Affiliate of WKKC described in clause (3);

(ii) shall not voluntarily dissolve or liquidate itself, any Affiliate of WKKC described in Section 4.2(b)(i), or any Affiliate of WKKC that that was a party to an Internal Distribution (including any action that is a liquidation for U.S. federal income tax purposes);

(iii) shall not (1) enter into any Proposed Acquisition Transaction or, to the extent WKKC has the right to prohibit any Proposed Acquisition Transaction, permit any Proposed Acquisition Transaction to occur, (2) redeem or otherwise repurchase (directly or through an Affiliate) any WKKC stock, or rights to acquire WKKC stock, except to the extent such repurchases satisfy Section 4.05(1)(b) of Revenue Procedure 96-30 (as in effect prior to the amendment of such Revenue Procedure by Revenue Procedure 2003-48), (3) 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 WKKC Capital Stock (including through the conversion of any class of WKKC Capital Stock into another class of WKKC Capital Stock), (4) merge or consolidate with any other Person (or cause or permit any Affiliate of WKKC that was a party to an Internal

15

Distribution to merge or consolidate with any other Person), or (5) take any other action or actions (including any action or transaction that would be reasonably likely to be inconsistent with any of the statements and representations made or set forth in the Tax Materials) which in the aggregate, when combined with any other direct or indirect changes in ownership of WKKC Capital Stock pertinent for purposes of Section 355(e) of the Code, would be reasonably likely to have the effect of causing or permitting one or more Persons (whether or not acting in concert) to acquire directly or indirectly stock representing a Fifty-Percent or Greater Interest in WKKC (or in any Affiliate of WKKC that was a party to an Internal Distribution) or otherwise jeopardize the Tax-Free Status of the Transactions; and

(iv) shall not, and shall not cause or permit any member of the WKKC Group to, sell, transfer, or otherwise dispose of or agree to, sell, transfer or otherwise dispose of (including in any transaction treated for U.S. federal income tax purposes as a sale, transfer, or disposition) assets (including any shares of capital stock of a Subsidiary) that, in the aggregate, constitute more than twenty percent (20%) of the consolidated gross assets of WKKC or the WKKC Group. The foregoing sentence shall not apply to (1) sales, transfers, or dispositions of assets in the ordinary course of business, (2) any cash paid to acquire assets from an unrelated Person in an arm’s-length transaction, (3) any assets transferred to a Person that is disregarded as an entity separate from the transferor for U.S. federal income tax purposes, or (4) any mandatory or optional repayment (or prepayment) of any indebtedness of WKKC or any member of the WKKC Group. The percentages of gross assets or consolidated gross assets of WKKC or the WKKC Group, as the case may be, sold, transferred, or otherwise disposed of, shall be based on the fair market value of the gross assets of WKKC and the members of the WKKC Group as of the Distribution Date. For purposes of this Section 4.2(b)(iv), a merger of WKKC or one of its Subsidiaries with and into any Person that is not a wholly-owned Subsidiary of WKKC shall constitute a disposition of all of the assets of WKKC or such Subsidiary.

(c) Notwithstanding the restrictions imposed by Section 4.2(b), WKKC or a member of the WKKC Group may take any of the actions or transactions described therein if WKKC either (i) obtains an Unqualified Tax Opinion in form and substance satisfactory to Kellanova in its sole and absolute discretion, or (ii) obtains the prior written consent of Kellanova waiving the requirement that WKKC obtain an Unqualified Tax Opinion, such waiver to be provided in ▇▇▇▇▇▇▇▇▇’s sole and absolute discretion. ▇▇▇▇▇▇▇▇▇’s evaluation of an Unqualified Tax Opinion may consider, among other factors, the appropriateness of any underlying assumptions, representations, and covenants made in connection with such opinion (and, for the avoidance of doubt, ▇▇▇▇▇▇▇▇▇ may determine that no opinion would be acceptable to ▇▇▇▇▇▇▇▇▇). WKKC shall bear all costs and expenses of securing any such Unqualified Tax Opinion and shall reimburse Kellanova for all reasonable out-of-pocket expenses that Kellanova or any of its Affiliates may incur in good faith in seeking to obtain or evaluate any such Unqualified Tax Opinion. Neither the delivery of an Unqualified Tax Opinion nor ▇▇▇▇▇▇▇▇▇’s waiver of WKKC’s obligation to deliver an Unqualified Tax Opinion shall limit or modify WKKC’s continuing indemnification obligation pursuant to Article V.

(c) To the extent that any Tax or Tax-Related Loss is subject to indemnity pursuant to both Sections 5.1(a)(ii) (on the one hand) and 5.1(b)(ii) or (iv) (on the other hand), responsibility for such Tax or Tax-Related Loss shall be shared by ▇▇▇▇▇▇▇▇▇ and WKKC according to relative fault as determined by ▇▇▇▇▇▇▇▇▇ in its good faith discretion (for the avoidance of doubt, subject to the provisions of Section 9.1).

Section 5.2 Indemnification Payments.

(a) Except as otherwise provided in this Agreement, if either Party (the “Indemnitee”) is required to pay to a Taxing Authority a Tax or to another Person a payment in respect of a Tax that the other Party (the “Indemnifying Party”) is liable for under this Agreement, including as a result of a Final Determination, the Indemnitee shall notify the Indemnifying Party, in writing, of its obligation to pay such Tax and, in reasonably sufficient detail, its calculation of the amount due by such Indemnifying Party to the Indemnitee, including any Tax-Related Losses attributable thereto. The Indemnifying Party shall pay such amount, including any Tax-Related Losses attributable thereto, to the Indemnitee no later than the later of (i) five (5) Business Days prior to the date on which such payment is due to the applicable Taxing Authority, and (ii) fifteen (15) Business Days after the receipt of notice from the other Party.

Section 5.3 Payment Mechanics.

(a) All payments under this Agreement shall be made by ▇▇▇▇▇▇▇▇▇ directly to WKKC and by WKKC directly to ▇▇▇▇▇▇▇▇▇; provided, however, that if the Parties mutually agree with respect to any such indemnification payment, any member of the Kellanova Group, on the one hand, may make such indemnification payment to any member of the WKKC Group, on the other hand, and vice versa. All indemnification payments shall be treated in the manner described in Section 5.4.

(b) In the case of any payment of Taxes made by a Responsible Party or Indemnitee pursuant to this Agreement for which such Responsible Party or Indemnitee, as the case may be, has received a payment from the other Party, such Responsible Party or Indemnitee shall provide to the other Party a copy of any official government receipt received with respect to the payment of such Taxes to the applicable Taxing Authority (or, if no such official governmental receipts are available, executed bank payment forms or other reasonable evidence of payment).

Section 5.4 Treatment of Payments. The Parties agree that any payment made between the Parties pursuant to this Agreement shall be treated for all U.S. federal income tax purposes, to the extent permitted by Law, as either (i) a non-taxable contribution by ▇▇▇▇▇▇▇▇▇ to WKKC, or (ii) a distribution by WKKC to Kellanova, and, in the case of any payment made between the Parties pursuant to this Agreement after the Distribution, such payment shall be treated as having been made immediately prior to the Distribution. Notwithstanding the foregoing, ▇▇▇▇▇▇▇▇▇ shall notify WKKC if it determines that any payment made pursuant to this Agreement is to be treated, for any Tax purposes, as a payment made by one Party acting as an agent of one of such Party’s Subsidiaries to the other Party acting as an agent of one of such other Party’s Subsidiaries, and the Parties agree to treat any such payment accordingly.

ARTICLE VI

A failure by an Indemnitee to give notice as provided in this Section 6.1 (or to promptly forward any such notices or communications) shall not relieve the Indemnifying Party of its indemnification obligation under this Agreement, except to the extent that the Indemnifying Party shall have been actually prejudiced by such failure.

18

Section 6.2 Separate Returns. In the case of any Tax Contest with respect to any Separate Return (other than a WKKC Separate Return for which Kellanova is liable pursuant to Section 2.1(b)(i), the Party having the liability for the Tax pursuant to Article II shall have the sole responsibility and right to control the prosecution of such Tax Contest, including the exclusive right to communicate with agents of the applicable Taxing Authority and to control, resolve, settle, or agree to any deficiency, claim, or adjustment proposed, asserted, or assessed in connection with or as a result of such Tax Contest.

During the pendency of any Tax Contest or threatened Tax Contest, each of the Parties shall provide prompt notice to the other Party of any written communication received by it or a member of its respective Group from a Taxing Authority regarding any Tax Contest for which it is indemnified by the other Party hereunder or for which it may be required to indemnify the other Party hereunder. Such notice shall attach copies of the pertinent portion of any written communication from a Taxing Authority and contain factual information (to the extent known) describing any asserted Tax liability in reasonable detail and shall be accompanied by copies of any notice and other documents received from any Taxing Authority in respect of any such matters. Such notice shall be provided in a reasonably timely fashion; provided, however, that in the event that timely notice is not provided, a Party shall be relieved of its obligation to indemnify the other Party only to the extent that such delay results in actual increased costs or actual prejudice to such other Party.

Section 6.5 Participation Rights. Unless waived by the Parties in writing, in connection with any potential adjustment in a Tax Contest as a result of which adjustment the Non-Controlling Party may reasonably be expected to become liable to make any indemnification payment to the Controlling Party under this Agreement (i) the Controlling Party shall keep the Non-Controlling Party informed in a timely manner of all actions taken or proposed to be taken by the Controlling Party with respect to such potential adjustment in such Tax Contest, (ii) the Controlling Party shall timely provide the Non-Controlling Party with copies of any correspondence or filings submitted to any Taxing Authority or judicial authority in connection with such potential adjustment in such Tax Contest, and (iii) the Controlling Party shall defend such Tax Contest diligently and in good faith. The failure of the Controlling Party to take any action specified in the preceding sentence with respect to the Non-Controlling Party shall not relieve the Non-Controlling Party of any liability or obligation which it may have to the Controlling Party under this Agreement, and in no event shall such failure relieve the Non-Controlling Party from any other liability or obligation which it may have to the Controlling Party, in each case except to the extent that the Non-Controlling Party is materially prejudiced by such failure.
