the Ralcorp Group (whether such Tax Attributes, Tax Benefits or reduction in Taxes are reported on an original Tax Return, arise pursuant to a Final Determination or otherwise). 

Section 3. Proration of Taxes. 
 3.01 General Method of Proration. Tax Items shall be apportioned between Pre-Distribution Periods and Post-Distribution Periods in accordance with the principles of Treasury Regulation

provisions of Treasury Regulation Section 1.1502-76(b)(2)(iii) will be applied to ratably allocate the items (other than extraordinary items) for the month which includes the Distribution Date. At Ralcorp’s election, in its sole
discretion, an election under Treasury Regulation Section 1.1502-76(b)(2)(ii)(D) (relating to ratable allocation of a year’s items) shall be made. At Ralcorp’s request, Post shall join in making an election under Treasury Regulation
Section 1.1502-76(b)(2)(ii)(D).

of Tax Items between Pre-Distribution Periods and Post-Distribution Periods, any Tax Items relating to the Transactions shall be treated as extraordinary items described in Treasury Regulation Section 1.1502-76(b)(2)(ii)(C) and shall (to the
extent occurring on or prior to the Distribution Date) be allocated to Pre-Distribution Periods, and any Taxes related to such items shall be treated under Treasury Regulation Section 1.1502-76(b)(2)(iv) as relating to such extraordinary item
and shall (to the extent occurring on or prior to the Distribution Date) be allocated to Pre-Distribution Periods.

account by the Ralcorp Group under Treas. Reg. Sections 1.1502-13 and 1.1502-19) shall be treated as arising in the Pre-Distribution Period. 
 Section 4. Preparation and Filing of Tax Returns.

of Tax where Ralcorp files a Joint Return that includes such Affiliate of Post; and 
 (b) all Straddle Period Returns.

 The Tax Returns required to be prepared and filed by Post under this Section 4.03 shall include any Post Tax Return for
Tax Periods beginning on or after the Distribution Date.

(a) General Rule. Except as provided in Section 4.04(b), any Tax Return for a Pre-Distribution Period or Straddle Period
shall be prepared in accordance with past practices, accounting methods, elections or conventions (“Past Practices”) used with respect to the Tax Returns in question (unless there is no reasonable basis for the use of such Past
Practices or unless there is no adverse effect to Ralcorp), and to the extent any items are not covered by Past Practices (or in the event that there is no reasonable basis for the use of such Past Practices or there is no adverse effect to
Ralcorp), in accordance with generally acceptable Tax accounting practices.

paragraph at least fifteen (15) days prior to the due date for filing of such Tax Return to provide the requesting party with a meaningful opportunity to analyze and comment on such Tax Return. 

4.07 Post Carrybacks, Carryforwards and Claims for Refund. Post hereby agrees that Ralcorp shall be entitled to determine
in its sole discretion whether (a) any Adjustment Request with respect to any Joint Return shall be filed to claim in any Pre-Distribution Period any Post Carried Item, and (b) any available elections shall be made to waive the right to

 5.01 Payment of Taxes. In the case of any Joint Return: 
 (a)
Computation and Payment of Tax Due. At least three (3) Business Days prior to any Payment Date for any Tax Return, Ralcorp shall compute the amount of Tax required to be paid to the applicable Tax Authority (taking into account
the requirements of Section 4.04 relating to consistent accounting practices, as applicable) with respect to such Tax Return on such Payment Date and shall notify Post of the amount Ralcorp has tentatively determined is required to be paid by
Post in respect of such Tax Return under this Agreement. Ralcorp shall pay such amount that Ralcorp has computed is required to be paid to the applicable Tax Authority to such Tax Authority on or before such Payment Date.

by evidence of payment and a statement detailing the Taxes paid and describing in reasonable detail the particulars relating thereto.

describing in reasonable detail the particulars relating thereto. 
 (c) All indemnification payments under this Agreement

 Section 6. Tax
Benefits. 
 6.01 Tax Benefits. 
 (a) Ralcorp shall be entitled to any refund (and any interest thereon received from the applicable Tax Authority) of Taxes received by any member of the Ralcorp Group or the Post Group, other than any
refund to which Post is entitled pursuant to Section 6.01(e). Post shall not be entitled to any refund (or any interest thereon received from the applicable Tax Authority), except as set forth in Section 6.01(e). A Company receiving a
refund to which another Company is entitled hereunder shall pay over such refund to such other Company within five (5) Business Days after such refund is received.

described in Section 2.01(b)(i)) shall be apportioned between the Pre-Distribution Period and the Post-Distribution Period pursuant to the principles set forth in Section 3 above. 

(c) For purposes of determining whether an adjustment to any Taxes for which a member of the Ralcorp Group is liable hereunder is
expected to result in a Tax Benefit for Post, the Post Group shall be deemed to be a Post Full Taxpayer. For purposes of determining the amount of Taxes for which the Ralcorp Group is, or is reasonably expected to be, liable as a result of an
adjustment pursuant to a Final Determination, the Ralcorp Group shall be deemed (i) not to utilize any Tax Attributes available to the Ralcorp Group and (ii) to be a Ralcorp Full Taxpayer. 

(d) No later than five (5) Business Days following a Final Determination described in Section 6.01(b), Ralcorp shall provide
Post with a written calculation of the amount payable to Ralcorp by Post pursuant to this Section 6. In the event that Post disagrees with any such calculation described in this Section 6.01(d), Post shall so notify Ralcorp in writing
within thirty (30) days of receiving the written calculation set forth above in this Section 6.01(d). Ralcorp and Post shall endeavor in good faith to resolve such disagreement, and, failing that, the amount payable under

Company or any member of its Group are and will be true, correct and complete. 
 7.02 Restrictions on Post. 

(a) Post agrees that it will not take or fail to take, or permit any Post Affiliate to take or fail to take, any action where such
action or failure to act would be inconsistent with or cause to be untrue any material, information, covenant or representation in any Representation Letters or Tax Opinions/Rulings. Post agrees that it will not take or fail to take, or permit any
Post Affiliate to take or fail to take, any action which prevents or could reasonably be expected to prevent (i) the Tax-Free Status, or (ii) any transaction contemplated by the Separation and Distribution Agreement which is intended by
the parties to be tax-free from so qualifying. 
 (b) Post agrees that, from the date hereof until the first day after the
two-year anniversary of the Distribution Date, it will (i) maintain its status as a company engaged in the Active Trade or Business for purposes of Section 355(b)(2) of the Code, and (ii) not engage in any transaction that would
result in it ceasing to be a company engaged in the Active Trade or Business for purposes of Section 355(b)(2) of the Code, in each case, taking into account Section 355(b)(3) of the Code. 

(c) Post agrees that, from the date hereof until the first day after the two-year anniversary of the Distribution Date, it will not:

 (i) enter into any Proposed Acquisition Transaction or, to the extent Post has the right to prohibit any
Proposed Acquisition Transaction, permit any Proposed Acquisition Transaction to occur (whether by (A) redeeming rights under a shareholder rights plan, (B) finding a tender offer to be a “permitted offer” under any such plan or
otherwise causing any such plan to be inapplicable or neutralized with respect to any Proposed Acquisition Transaction, or (C) approving any Proposed Acquisition Transaction, whether for purposes of Section 203 of the DGCL or any similar
corporate statute, any “fair price” or other provision of Post’ charter or bylaws or otherwise), 

(ii) merge or consolidate with any other Person or liquidate or partially liquidate, 

(iii) in a single transaction or series of transactions sell or transfer (other than sales or transfers of inventory in
the ordinary course of business) all or substantially all of the assets that were transferred to Post pursuant to the Post Contribution or sell or transfer 60% or more of the gross assets of the Active Trade or Business or 60% or more of the
consolidated gross assets of Post and its Affiliates (such percentages to be measured based on fair market value as of the Distribution Date),

 14 









 (v) amend its certificate of incorporation (or other organizational
documents), or take any other action, whether through a stockholder vote or otherwise, affecting the voting rights of Post Capital Stock (including, without limitation, through the conversion of one class of Post Capital Stock into another class of
Post Capital Stock), or 
 (vi) take any other action or actions (including any action or transaction that would
be reasonably likely to be inconsistent with any representation made in the Representation Letters or the Tax Opinions/Rulings) which in the aggregate (and taking into account any other transactions described in this subparagraph (d)) 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 Post or otherwise jeopardize the
Tax-Free Status, 
 unless prior to taking any such action set forth in the foregoing clauses (i) through (vi), (A) Post shall have
requested that Ralcorp obtain a Ruling in accordance with Section 7.04(b) and (d) of this Agreement to the effect that such transaction will not affect the Tax-Free Status and Ralcorp shall have received such a Ruling in form and substance
satisfactory to Ralcorp in its sole and absolute discretion, which discretion shall be exercised in good faith solely to preserve the Tax-Free Status (and in determining whether a Ruling is satisfactory, Ralcorp may consider, among other factors,
the appropriateness of any underlying assumptions and management’s representations made in connection with such Ruling), or (B) Post shall provide Ralcorp with an Unqualified Tax Opinion in form and substance satisfactory to Ralcorp in its
sole and absolute discretion, which discretion shall be exercised in good faith solely to preserve the Tax-Free Status (and in determining whether an opinion is satisfactory, Ralcorp may consider, among other factors, the appropriateness of any
underlying assumptions and management’s representations if used as a basis for the opinion and Ralcorp may determine that no opinion would be acceptable to Ralcorp) or (C) Ralcorp shall have waived the requirement to obtain such Ruling or
Unqualified Tax Opinion. 
 (d) If Post proposes to enter into any Section 7.02(d) Acquisition Transaction or, to the
extent Post has the right to prohibit any Section 7.02(d) Acquisition Transaction, proposes to permit any Section 7.02(d) Acquisition Transaction to occur, in each case, during the period from the date hereof until the first day after the
two-year anniversary of the Distribution Date, Post shall provide Ralcorp, no later than ten (10) days following the signing of any written agreement with respect to the Section 7.02(d) Acquisition Transaction, with a written description
of such transaction (including the type and amount of Post Capital Stock to be issued in such transaction) and a certificate of the Board of Directors of Post to the effect that the Section 7.02(d) Acquisition Transaction is not a Proposed
Acquisition Transaction or any other transaction to which the requirements of Section 7.02(c) apply (a “Board Certificate”). 
 7.03 Restrictions on Ralcorp. Ralcorp agrees that it will not take or fail to take, or permit any member of the Ralcorp Group to take or fail to take, any action where such action or failure
to act would be inconsistent with or cause to be untrue any material, information, covenant or representation in any Representation Letters or Tax Opinions/Rulings. Ralcorp agrees that it will not take or fail to take, or permit any member of the
Ralcorp Group to take or fail to take, any action which prevents or could reasonably be expected to prevent (a) the Tax-Free Status, or (b) any other transaction contemplated by the Separation and Distribution Agreement which is intended
by the parties to be tax-free from so qualifying; provided, however, that this Section 7.03 shall not be construed as obligating Ralcorp to consummate the Distribution without the satisfaction or waiver of all conditions set forth
in Section 8.01 of the Separation and Distribution Agreement nor shall it be construed as preventing Ralcorp from terminating the Separation and Distribution Agreement pursuant to Section 14.13 thereof. 

7.04 Procedures Regarding Opinions and Rulings. 
 (a) If Post notifies Ralcorp that it desires to take one of the actions described in clauses (i) through (vi) of Section 7.02(c) (a “Notified Action”), Ralcorp and Post
shall reasonably cooperate to attempt to obtain the Ruling or Unqualified Tax Opinion referred to in Section 7.02(c), unless Ralcorp shall have waived the requirement to obtain such Ruling or Unqualified Tax Opinion. 

  
 15 









 (b) Ralcorp agrees that at the reasonable request of Post pursuant to Section 7.02(c),
Ralcorp shall cooperate with Post and use its commercially reasonable efforts to seek to obtain, as expeditiously as possible, a Ruling from the IRS or an Unqualified Tax Opinion for the purpose of permitting Post to take the Notified Action.
Further, in no event shall Ralcorp be required to file any Ruling Request under this Section 7.04(b) unless Post represents that (i) it has reviewed the Ruling Request, and (ii) all information and representations, if any, relating to
any member of the Post Group, contained in the Ruling Request documents are (subject to any qualifications therein) true, correct and complete. Post shall reimburse Ralcorp for all reasonable costs and expenses incurred by the Ralcorp Group in
obtaining a Ruling or Unqualified Tax Opinion requested by Post within ten (10) Business Days after receiving an invoice from Ralcorp therefor. 
 (c) Ralcorp shall have the right to obtain a Ruling or a Tax opinion with respect to the Transactions (including an Unqualified Tax Opinion) at any time in its sole and absolute discretion. If Ralcorp
determines to obtain such a Ruling or an Unqualified Tax Opinion, Post shall (and shall cause each Affiliate of Post to) cooperate with Ralcorp and take any and all actions reasonably requested by Ralcorp in connection with obtaining the Ruling or
Unqualified Tax Opinion (including, without limitation, by making any representation or covenant or providing any materials or information requested by the IRS or Tax Advisor; provided that Post shall not be required to make (or cause any
Affiliate of Post to make) any representation or covenant that is inconsistent with historical facts or as to future matters or events over which it has no control). Ralcorp and Post shall each bear its own costs and expenses in obtaining a Ruling
or an Unqualified Tax Opinion requested by Ralcorp. 
 (d) Post hereby agrees that Ralcorp shall have sole and exclusive
control over the process of obtaining any Ruling, and that only Ralcorp shall apply for a Ruling. In connection with obtaining a Ruling pursuant to Section 7.04(b), (i) Ralcorp shall keep Post informed in a timely manner of all material
actions taken or proposed to be taken by Ralcorp in connection therewith; (ii) Ralcorp shall (A) reasonably in advance of the submission of any Ruling Request documents provide Post with a draft copy thereof, (B) reasonably consider
Post’ comments on such draft copy, and (C) provide Post with a final copy; and (iii) Ralcorp shall provide Post with notice reasonably in advance of, and Post shall have the right to attend, any formally scheduled meetings with the
IRS (subject to the approval of the IRS) that relate to such Ruling. Neither Post nor any Post Affiliate directly or indirectly controlled by Post shall seek any guidance from the IRS or any other Tax Authority (whether written, verbal or otherwise)
at any time concerning the Transactions (including the impact of any transaction on the Transactions). 
 Section 8.
Assistance and Cooperation.

agents, including accounting firms and legal counsel, in connection with Tax matters covered by this Agreement relating to the Companies and their Affiliates including (i) preparation and filing of Tax Returns, (ii) determining the
liability for and amount of any Taxes due (including estimated Taxes) or the right to and amount of any refund of Taxes, (iii) examinations of Tax Returns, and (iv) any administrative or judicial proceeding in respect of Taxes assessed or
proposed to be assessed. Such cooperation shall include making all information and documents in their possession relating to the other Companies and their Affiliates available to such other Companies as provided in Section 9. The Companies

information and documents relevant to Taxes, and personnel reasonably required as witnesses or for purposes of providing information or documents in connection with any administrative or judicial proceedings relating to Taxes. 

(b) Any information or documents provided under this Section 8 shall be kept confidential by the Company receiving the information
or documents, except as may otherwise be necessary in connection with the filing of Tax Returns or in connection with any administrative or judicial proceedings relating to Taxes. Notwithstanding any other provision of this Agreement or any other
agreement, (i) neither Ralcorp nor any Ralcorp 

  
 16 









 
Affiliate shall be required to provide Post or any Post Affiliate or any other Person access to or copies of any information or procedures (including the proceedings of any Tax Contest) other
than information or procedures that relate solely to Post, the business or assets of Post or any Post Affiliate or matters in which Post has an obligation to indemnify under this Agreement, and (ii) in no event shall Ralcorp or any Ralcorp
Affiliate be required to provide Post, any Post Affiliate or any other Person access to or copies of any information if such action could reasonably be expected to result in the waiver of any Privilege. In addition, in the event that Ralcorp
determines that the provision of any information to Post or any Post Affiliate could be commercially detrimental, violate any law or agreement or waive any Privilege, the parties shall use reasonable best efforts to permit compliance with its
obligations under this Section 8 in a manner that avoids any such harm or consequence. 
 (c) Following the acquisition of
assets or stock relating to Post Canada, Post shall, upon the request of Ralcorp, cause the entity holding the assets or stock relating to Post Business in Canada to join in making an election under section 167 of the Canada Revenue Agency Excise
Tax Act with respect to any Canadian federal goods and services tax imposed on such purchase. 
 8.02 Income Tax Return
Information. 
 (a) Post and Ralcorp acknowledge that time is of the essence in relation to any request for information,
assistance or cooperation made by Ralcorp or Post pursuant to Section 8.01 or this Section 8.02. Post and Ralcorp acknowledge that failure to conform to the deadlines set forth herein or reasonable deadlines otherwise set by Ralcorp or
Post could cause irreparable harm. 
 (b) The Companies shall provide to the other Companies information and documents relating
to its Group, and in its possession, that are required by the other Companies to prepare Tax Returns. Any information or documents the Responsible Company requires to prepare such Tax Returns shall be provided in such form as the Responsible Company
reasonably requests and in sufficient time for the Responsible Company to file such Tax Returns on a timely basis. 
 8.03
Reliance by Ralcorp. If any member of the Post Group supplies information to a member of the Ralcorp Group in connection with a Tax liability and an officer of a member of the Ralcorp Group signs a statement or other document under penalties
of perjury in reliance upon the accuracy of such information, then upon the written request of such member of the Ralcorp Group identifying the information being so relied upon, the chief financial officer of Post (or any officer of Post as
designated by the chief financial officer of Post) shall certify in writing that to his or her knowledge (based upon consultation with appropriate employees) the information so supplied is accurate and complete. Post agrees to indemnify and hold
harmless each member of the Ralcorp Group and its directors, officers and employees from and against any fine, penalty, or other cost or expense of any kind attributable to a member of the Post Group having supplied, pursuant to this Section 8,
a member of the Ralcorp Group with inaccurate or incomplete information in connection with a Tax liability. 
 8.04 Reliance
by Post. If any member of the Ralcorp Group supplies information to a member of the Post Group in connection with a Tax liability and an officer of a member of the Post Group signs a statement or other document under penalties of perjury in
reliance upon the accuracy of such information, then upon the written request of such member of the Post Group identifying the information being so relied upon, the chief financial officer of Ralcorp (or any officer of Ralcorp as designated by the
chief financial officer of Ralcorp) shall certify in writing that to his or her knowledge (based upon consultation with appropriate employees) the information so supplied is accurate and complete. Ralcorp agrees to indemnify and hold harmless each
member of the Post Group and its directors, officers and employees from and against any fine, penalty, or other cost or expense of any kind attributable to a member of the Ralcorp Group having supplied, pursuant to this Section 8, a member of
the Post Group with inaccurate or incomplete information in connection with a Tax liability.

 Section 9. Tax Records. 

9.01 Retention of Tax Records. The Companies shall preserve and keep all Tax Records in their possession and exclusively relating
to the assets and activities of their Group for Pre-Distribution Periods, and Ralcorp shall preserve and keep all other Tax Records relating to Taxes of the Groups for Pre-Distribution Tax Periods, for so long as the contents thereof may become
material in the administration of any matter under the Code or other applicable Tax Law, but in any event until the later of (a) the expiration of any applicable statutes of limitations, or (b) seven (7) years after the Distribution
Date (such later date, the “Retention Date”). After the Retention Date, a Company may dispose of such Tax Records upon ninety (90) days’ prior written notice to the other Companies. If, prior to the Retention Date, a
Company reasonably determines that any Tax Records which it would otherwise be required to preserve and keep under this Section 9 are no longer material in the administration of any matter under the Code or other applicable Tax Law and the
other Companies agree, then such first Company may dispose of such Tax Records upon ninety (90) days’ prior notice to the other Companies. Any notice of an intent to dispose given pursuant to this Section 9.01 shall include a list of
the Tax Records to be disposed of describing in reasonable detail each file, book, or other record accumulation being disposed. The notified Company shall have the opportunity, at its cost and expense, to copy or remove, within such 90-day period,
all or any part of such Tax Records. If, at any time prior to the Retention Date, Post determines to decommission or otherwise discontinue any computer program or information technology system used to access or store any Tax Records, then Post may
decommission or discontinue such program or system upon ninety (90) days’ prior notice to Ralcorp and Ralcorp shall have the opportunity, at its cost and expense, to copy, within such 90-day period, all or any part of the underlying data
relating to the Tax Records accessed by or stored on such program or system. 
 9.02 Access to Tax Records. The
Companies and their respective Affiliates shall make available to each other for inspection and copying during normal business hours upon reasonable notice all Tax Records (and, for the avoidance of doubt, any pertinent underlying data accessed or
stored on any computer program or information technology system) in their possession and shall permit the other Companies and their Affiliates, authorized agents and representatives and any representative of a Taxing Authority or other Tax auditor
direct access during normal business hours upon reasonable notice to any computer program or information technology system used to access or store any Tax Records, in each case to the extent reasonably required by the other Companies in connection
with the preparation of Tax Returns or financial accounting statements, audits, litigation, or the resolution of items under this Agreement. 
 Section 10. Tax Contests. 
 10.01 Notice. A Company shall
provide prompt notice to the other Companies of any written communication from a Tax Authority regarding any pending or threatened Tax audit, assessment or proceeding or other Tax Contest of which it becomes aware related to Taxes for Tax Periods
for which it is indemnified by another Company hereunder, provided, however, that the indemnifying Company shall not be relieved of its obligations hereunder by reason of any failure by the indemnified Company to so notify except to the extent such
failure actually prejudices the indemnifying Company. Such notice shall attach copies of the pertinent portion of any written communication from a Tax 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 Tax Authority in respect of any such matters. 
 10.02 Control of Tax Contests. 
 (a) Ralcorp. Ralcorp may elect to
control, and have the sole discretion in handling, settling or contesting, subject to Sections 10.02(d) and (e) below, any Tax Contest relating to (i) all Tax Returns for which Ralcorp is responsible for preparing and filing under
Section 4.02, (ii) all Transfer Taxes, (iii) all Transaction Taxes assessed against Ralcorp or members of the Ralcorp Group by the applicable Taxing Authority and (iv) the Tax treatment of the Transactions. 

  
 18 









 (b) Post. Post may elect to control, and have the sole discretion in handling,
settling or contesting, subject to Sections 10.02(d) and (e) below, any Tax Contest relating to (i) all Tax Returns for which Post is responsible for preparing and filing under Section 4.03, (ii) all Transaction Taxes assessed
against Post by the applicable Taxing Authority, and (iii) all Recoverable Taxes. 
 (c) Joint Returns and Certain
Other Returns. In the case of any Tax Contest with respect to any Joint Return or Ralcorp State Combined Income Tax Return, Ralcorp shall have exclusive control over the Tax Contest, including exclusive authority with respect to any
settlement of such Tax liability, subject to Sections 10.02(d) and (e) below. 
 (d) Settlement Rights. The
Controlling Party shall have the sole right to contest, litigate, compromise and settle any Tax Contest without obtaining the prior consent of the Non-Controlling Party. 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 (or any payment under Section 6) 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 provide the Non-Controlling Party copies of any written materials relating to such potential adjustment in such Tax Contest received from any Tax Authority; (iii) the Controlling Party shall timely provide
the Non-Controlling Party with copies of any correspondence or filings submitted to any Tax Authority or judicial authority in connection with such potential adjustment in such Tax Contest; and (iv) the Controlling Party shall consult with the
Non-Controlling Party and offer the Non-Controlling Party a reasonable opportunity to comment before submitting any written materials prepared or furnished in connection with such potential adjustment in such Tax Contest. 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 and/or obligation which it may have to the Controlling Party under this
Agreement except to the extent that the Non-Controlling Party was actually harmed by such failure, 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 the case of any Tax Contest described in Section 10.02(a) or (b), “Controlling Party” means the Company entitled to control the Tax Contest under such Section and “Non-Controlling Party” means the
other Company. 
 (e) Tax Contest Participation. Unless waived by the parties in writing, the Controlling Party
shall provide the Non-Controlling Party with written notice reasonably in advance of, and the Non-Controlling Party shall have the right to request to attend, any formally scheduled meetings with Tax Authorities or hearings or proceedings before any
judicial authorities in connection with any potential adjustment in a Tax Contest pursuant to which the Non-Controlling Party may reasonably be expected to become liable to make any indemnification payment (or any payment under Section 6) to
the Controlling Party under this Agreement. The failure of the Controlling Party to provide any notice specified in this Section 10.02(e) to the Non-Controlling Party shall not relieve the Non-Controlling Party of any liability and/or
obligation which it may have to the Controlling Party under this Agreement except to the extent that the Non-Controlling Party was actually harmed by such failure, 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. 
 (f) Power of Attorney. Each member of the
Post Group shall execute and deliver to Ralcorp (or such member of the Ralcorp Group as Ralcorp shall designate) any power of attorney or other similar document reasonably requested by Ralcorp (or such designee) in connection with any Tax Contest
(as to which Ralcorp is the Controlling Party) described in this Section 10. 
 Section 11. Effective Date;
Termination of Prior Intercompany Tax Allocation Agreements. This Agreement shall be effective as of the date hereof. As of the date hereof, (a) all prior intercompany Tax allocation agreements or arrangements shall be terminated, and
(b) amounts due under or contemplated by such agreements or arrangements as of the date hereof shall be settled as of the date hereof. Upon such termination and settlement, no further payments by or to Ralcorp or by or to Post, with respect to
such agreements or 

  
 19 









 
arrangements shall be made, and all other rights and obligations resulting from such agreements or arrangements between the Companies and their Affiliates shall cease at such time. Any payments
pursuant to such agreements or arrangements shall be disregarded for purposes of computing amounts due under this Agreement. 

Section 12. Survival of Obligations. The representations, warranties, covenants and agreements set forth in this Agreement
shall be unconditional and absolute and shall remain in effect without limitation as to time. 
 Section 13. Treatment
of Payments; Tax Gross Up. 
 13.01 Treatment of Tax Indemnity and Tax Benefit Payments. In the absence of any change
in Tax treatment under the Code or other applicable Tax Law any Tax Indemnity and/or Tax Benefit payments made by a Company under this Agreement shall, to the extent permitted by Tax Law, be reported for Tax purposes by the payor and the recipient
as distributions or capital contributions, as appropriate, occurring immediately before the Distribution. 
 13.02 Tax Gross
Up. If notwithstanding the manner in which Tax indemnity payments and Tax Benefit payments were reported, there is an adjustment to the Tax liability of a Company as a result of its receipt of a payment pursuant to this Agreement, such payment
shall be appropriately adjusted so that the amount of such payment, reduced by the amount of all Income Taxes payable with respect to the receipt thereof (but taking into account all correlative Tax Benefits resulting from the payment of such Income
Taxes), shall equal the amount of the payment which the Company receiving such payment would otherwise be entitled to receive pursuant to this Agreement. 
 13.03 Interest Under This Agreement. Anything herein to the contrary notwithstanding, to the extent one Company (“Indemnitor”) makes a payment of interest to another Company
(“Indemnitee”) under Section 15 of this Agreement, the interest payment shall be treated as interest expense to the Indemnitor (deductible to the extent provided by law) and as interest income by the Indemnitee (includible in
income to the extent provided by law). The amount of the payment shall not be adjusted under Section 2.02 to take into account any associated Tax Benefit to the Indemnitor or increase in Tax to the Indemnitee. 

Section 14. Disagreements. Post and Ralcorp mutually desire that friendly collaboration will continue between them.
Accordingly, they will try, and they will cause their respective Group members to try, to resolve in an amicable manner all disagreements and misunderstandings connected with their respective rights and obligations under this Agreement, including
any amendments hereto. In furtherance thereof, in the event of any dispute or disagreement (a “Tax Dispute”) between any member of the Ralcorp Group and any member of the Post Group as to the interpretation of any provision of this
Agreement or the performance of obligations hereunder, the Tax departments of the Companies shall negotiate in good faith to resolve the Tax Dispute. If such good faith negotiations do not resolve the Tax Dispute, then the matter shall be resolved
pursuant to the procedures set forth in Article XII of the Separation and Distribution Agreement, provided, however, that upon the request of either Company, the arbitrator selected by each of the parties pursuant to Section 12.04 of the
Separation and Distribution Agreement shall be a recognized tax professional, such as a United States tax counsel or accountant of recognized national standing. Nothing in this Section 14 will prevent either Company from seeking injunctive
relief if any delay resulting from the efforts to resolve the Tax Dispute through the procedures set forth in Article XII of the Separation and Distribution Agreement could result in serious and irreparable injury to either Company. Notwithstanding
anything to the contrary in this Agreement, the Separation and Distribution Agreement or any Transaction Agreements, Ralcorp and Post are the only members of their respective Group entitled to commence a dispute resolution procedure under this
Agreement, and each of Ralcorp and Post will cause its respective Group members not to commence any dispute resolution procedure other than through such party as provided in this Section 14. 

Section 15. Late Payments. Any amount owed by one party to another party under this Agreement which is not paid when due
shall bear interest at the Prime Rate plus two percent, compounded semiannually, from the due date of the payment to the date paid. To the extent interest required to be paid under this Section 15


  
 20 









 
duplicates interest required to be paid under any other provision of this Agreement, interest shall be computed at the higher of the interest rate provided under this Section 15 or the
interest rate provided under such other provision. 
 Section 16. Expenses. Except as otherwise provided in this
Agreement or the Transition Services Agreement, each party and its Affiliates shall bear their own expenses incurred in connection with preparation of Tax Returns, Tax Contests, and other matters related to Taxes under the provisions of this
Agreement. 
 Section 17. General Provisions. 

17.01 No Double Recovery. No provision of this Agreement shall be construed to provide an indemnity or other recovery for any
costs, damages, or other amounts for which the damaged party has been fully compensated under any other provision of this Agreement or under any other agreement or action at law or equity. Unless expressly required in this Agreement, a party shall
not be required to exhaust all remedies available under other agreements or at law or equity before recovering under the remedies provided in this Agreement. 
 17.02 Entire Agreement. This Agreement and the Transaction Agreements, including the Schedules and Exhibits referred to herein and therein and the documents delivered pursuant hereto and thereto,
constitute the entire agreement between any of the parties hereto with respect to the subject matter contained herein or therein, and supersede all prior agreements, negotiations, discussions, understandings and commitments, written or oral, between
any of the parties hereto with respect to such subject matter. 
 17.03 Choice of Law. THIS AGREEMENT SHALL BE GOVERNED
BY AND CONSTRUED AND ENFORCED IN ACCORDANCE WITH THE SUBSTANTIVE LAWS OF THE STATE OF MISSOURI, WITHOUT REGARD TO ANY CONFLICTS OF LAW PROVISION OR RULE THEREOF THAT WOULD RESULT IN THE APPLICATION OF THE LAWS OF ANY OTHER JURISDICTION. 

17.04 Amendment. This Agreement shall not be amended, modified or supplemented except by a written instrument signed by an
authorized representative of Ralcorp and Post. 
 17.05 Waiver. Any term or provision of this Agreement may be waived, or
the time for its performance may be extended, by the Company or Companies entitled to the benefit thereof. Any such waiver shall be validly and sufficiently given for the purposes of this Agreement if, as to any Company, it is in writing signed by
an authorized representative of such Company. The failure of any Company to enforce at any time any provision of this Agreement shall not be construed to be a waiver of such provision, or in any way to affect the validity of this Agreement or any
part hereof or the right of any Company thereafter to enforce each and every such provision. No waiver of any breach of this Agreement shall be held to constitute a waiver of any other or subsequent breach. 

17.06 Partial Invalidity. Wherever possible, each provision hereof shall be interpreted in such a manner as to be effective and
valid under applicable law, but in case any one or more of the provisions contained herein shall, for any reason, be held to be invalid, illegal or unenforceable in any respect, such provision or provisions shall be ineffective to the extent, but
only to the extent, of such invalidity, illegality or unenforceability without invalidating the remainder of such provision or provisions or any other provisions hereof, unless such a construction would be unreasonable. 

17.07 Execution in Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed an
original instrument, but all of which shall be considered one and the same agreement, and shall become binding when one or more counterparts have been signed by and delivered to each of the parties hereto. 

17.08 Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties hereto and their
successors and permitted assigns; provided, however, that the rights and obligations of any Company under this Agreement shall not be assignable by such Company without the prior written consent of


  
 21 









 
the other parties hereto. The successors and permitted assigns hereunder shall include any permitted assignee as well as the successors in interest to such permitted assignee (whether by merger,
liquidation (including successive mergers or liquidations) or otherwise). 
 17.09 Notices. All notices, requests,
claims, demands and other communications required or permitted hereunder shall be in writing and shall be deemed duly given or delivered (a) when delivered personally, (b) if transmitted by facsimile when confirmation of transmission is
received or by email when receipt of such email is acknowledged by return email, (c) if sent by registered or certified mail, postage prepaid, return receipt requested, on the third business day after mailing or (d) if sent by private

 ANNEX I 
 Series of Transactions 
  

	A.	Ralcorp forms a new wholly-owned subsidiary, Post, which will be Missouri corporation. 


 

	B.	Post borrows funds from one or more unrelated third parties (the “Post Credit Facility”). Ralcorp contributes all of the equity interest in Post US to
Post (“Post Contribution”) in exchange for additional shares of Post, a portion of the borrowing proceeds and newly issued securities of Post (“Post Debt Securities”). The borrowing proceeds retained by Post will be
used to pay the purchase price for the Canada Sale (defined below) and for working capital. 

  

	C.	Post will use a portion of the borrowing proceeds to acquire the portion of the Post Business located in Canada from Post Foods Canada Corporation (or its successor or
affiliate) through either a direct or indirect stock or asset purchase (the “Canada Sale”), to be held in a newly formed Canadian entity (“New Post Canada”). 


 

	D.	Ralcorp will distribute at least 80% of the stock of Post pro rata to its shareholders (the “Distribution”) and will retain no more than 20% of
the stock of Post (the “Retained Shares;” the retention of the Retained Shares by Ralcorp is referred to herein as the “Share Retention”). 


 

	E.	Before or after any of the foregoing, Ralcorp will borrow cash from one or more financial institutions (the “Ralcorp Debt”). At a time when the
financial institution(s) have held the Ralcorp Debt for no less than 5 days, Ralcorp and the financial institution(s) then holding the Ralcorp Debt may enter into (i) an exchange agreement (the “Debt for Debt Exchange
Agreement”) pursuant to which the parties agree to exchange an amount of Ralcorp Debt to be determined by the parties bargaining at arm’s length for Post Debt Securities, and/or (ii) an exchange agreement (the “Equity for
Debt Exchange Agreement”) pursuant to which the parties agree to exchange an amount of Ralcorp Debt to be determined by the parties bargaining at arm’s length for Retained Shares. 


 

	F.	At a time when the financial institution(s) or their affiliates have held the Ralcorp Debt as principals for at least 14 days, (i) if a Debt for Debt Exchange
Agreement has been entered into, Ralcorp will transfer the Post Debt Securities to the financial institution(s) in repayment of all or a portion of the Ralcorp Debt (the “Debt for Debt Exchange”), and (ii) if an Equity for Debt
Exchange Agreement has been entered into, Ralcorp will transfer the Retained Shares to the financial institution(s) in repayment of all or a portion of the Ralcorp Debt (the “Equity for Debt Exchange”). 


 

	G.	If market conditions are conducive, Ralcorp, pursuant to the plan that includes the Distribution, intends to transfer any remaining Retained Shares to its shareholders
in exchange for shares of Ralcorp Common Stock (the “Share Repurchase”). Any Share Repurchase will in no event be completed later than 12 months following the Distribution. Any of the Retained Shares not disposed of in the Share
Repurchase will be disposed of as soon as commercially practicable, but in any event not later than 5 years after the Distribution.
