WHEREAS, Holcim, acting through its direct and indirect Subsidiaries, currently conducts a number of businesses, including the SpinCo Business;

WHEREAS, the Board of Directors of Holcim (the “Holcim Board”) has determined that it is advisable and in the best interests of Holcim to separate Holcim into two separate, independent, publicly traded companies: (i) one comprising the Holcim Business, which shall continue to be owned and conducted, directly or indirectly, by Holcim, which will continue to be owned by the existing holders of ordinary shares of Holcim (the “Holcim Shares”), and (ii) one comprising the SpinCo Business, which shall be owned and conducted directly or indirectly by SpinCo, ordinary shares of which are intended to be distributed on a pro rata basis to existing holders of Holcim Shares (other than members of the Holcim Group who hold Holcim Shares in treasury or otherwise), with the balance of ordinary shares of SpinCo to be contributed to SpinCo prior to the Distribution (as defined below);

WHEREAS, in furtherance of the foregoing, the Holcim Board has determined that it is advisable and in the best interests of Holcim: (i) for Holcim and its Subsidiaries to enter into a series of transactions whereby Holcim and its Subsidiaries will be reorganized such that (A) Holcim and/or one or more other members of the Holcim Group will own all of the Holcim Assets and assume (or retain) all of the Holcim Liabilities, and (B) SpinCo and/or one or more other members of the SpinCo Group will own all of the SpinCo Assets and assume (or retain) all of the SpinCo Liabilities (the transactions referred to in this clause (i) being referred to herein as the “Separation”); and (ii) thereafter, for Holcim to (x) distribute to the existing holders of Holcim Shares (other than members of the Holcim Group who hold Holcim Shares in treasury or otherwise) as of the close of business on the Cum-Dividend Date, on a pro rata basis and based on the distribution ratio determined by the Holcim Board, a number of ordinary shares of SpinCo (“SpinCo Shares”) (such transactions described in this clause (ii)(x), the “Distribution”), and (y) contribute the balance of SpinCo Shares to SpinCo as of the Effective Time, to be held by SpinCo as treasury shares (such transactions described in this clause (ii)(y), the “SpinCo Share Contribution”), such that no member of the Holcim Group will continue to own any SpinCo Shares following the Distribution;

WHEREAS, the holders of Holcim Shares have further resolved, on the terms contemplated by the Separation Agreement, that Holcim shall effect the Distribution by means of a distribution of an extraordinary dividend of the SpinCo Shares to holders of Holcim Shares in accordance with the terms and conditions thereby;

WHEREAS, in furtherance of the foregoing, the holders of a majority of Holcim Shares represented at the annual general meeting of Holcim held at 9:00 a.m., Zurich time, on May 14, 2025 at ▇▇▇▇▇▇▇ Arena, ▇▇▇▇▇▇▇-▇▇▇▇▇▇-▇▇▇▇▇▇▇ ▇, ▇▇▇▇ ▇▇▇, ▇▇▇▇▇▇▇▇▇▇▇ (the “Holcim AGM”) approved, among other things, the Distribution and certain related matters necessary to declare and effectuate the Distribution in accordance with Swiss Law (such approval, the “Shareholder Approval”);

WHEREAS, SpinCo has not engaged in activities except those in connection with the transactions contemplated by the Internal Reorganization Steps Plan, the consummation of the transactions contemplated by this Agreement and those activities necessary in connection with its standup as an independent company (including activities with respect to the SpinCo Financing Arrangements, the SIX listing and the transactions contemplated by this Agreement);

WHEREAS, the Board of Directors of SpinCo has determined that it is advisable and in the best interests of SpinCo to effectuate the transactions contemplated by the Separation and Internal Reorganization Steps Plan;

WHEREAS, the Parties intend that the Distribution, together with certain internal reorganization transactions undertaken in anticipation of the Distribution, generally will qualify as tax-free for U.S. federal income tax purposes under Sections 368(a)(1)(D), 361 and 355 of the United States Internal Revenue Code of 1986, as amended (the “Code”);

WHEREAS, the Parties have executed a plan of reorganization and intend that it qualify as a “plan of reorganization” in accordance with Section 368 of the Code;

WHEREAS, the Parties intend that the contribution by ▇▇▇▇▇▇ of the SpinCo Assets to the SpinCo Group as well as the Distribution, together with certain internal reorganization transactions undertaken as part of the Separation, be generally recognized and treated as a tax neutral restructuring for Swiss tax purposes;

WHEREAS, it is appropriate and desirable to set forth the principal corporate transactions required to effect the Separation and to set forth certain other agreements that will, following the Distribution, govern certain matters relating to the Separation and the relationship of SpinCo and Holcim and their respective Groups;

WHEREAS, certain members of the Holcim Group, on the one hand, and certain members of the SpinCo 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 Intended Tax Treatment.

No member of the SpinCo Group or the Holcim Group shall have any continuing rights or obligations to any member of the other Group under any such agreement, and this Agreement shall be the sole Tax sharing agreement between the members of the Holcim Group, on the one hand, and the members of the SpinCo Group, on the other hand. Each Party shall, after the Distribution, at the reasonable request of the other Party, take, or cause to be taken, such other actions as may be necessary to effect the foregoing.

ARTICLE III

PREPARATION AND FILING OF TAX RETURNS

3.1 Holcim’s Responsibility. Holcim shall prepare and file, or shall cause to be prepared and filed, when due (taking into account any applicable extensions) (a) all Joint Returns, (b) all Tax Returns required to be filed by any member of the Holcim Group under applicable Law, and (c) all Tax Returns required to be filed by any member of the SpinCo Group under applicable Law that are due on or prior to the Distribution Date.

3.2 SpinCo’s Responsibility. SpinCo shall prepare and file, or shall cause to be prepared and filed, when due (taking into account any applicable extensions) all Tax Returns required to be filed by any member of the SpinCo Group under applicable Law that are due following the Distribution Date. For the avoidance of doubt, SpinCo shall prepare any transfer pricing documentation required to be prepared with respect to a Tax Return required to be prepared and filed under this Section 3.2.

3.3 Right To Review Tax Returns. To the extent that the positions taken on any Tax Return (i) directly relate to matters for which the Reviewing Party may have an indemnification obligation to the Preparing Party, or that may give rise to a refund to which the Reviewing Party would be entitled under this Agreement or (ii) would reasonably be expected to materially affect the Tax position of the Reviewing Party, the Preparing Party (at its own cost and expense) shall provide a draft of such Tax Return (or the relevant portion thereof) to the Reviewing Party for its review and comment at least thirty (30) days prior to the due date for such Tax Return (taking into account any applicable extensions), and shall use commercially reasonable efforts to modify such Tax Return before filing to include the Reviewing Party’s reasonable comments; provided, however, that nothing herein shall prevent the Preparing Party from timely filing any such Tax Return. The Parties shall attempt in good faith to resolve any issues arising out of the review of any such portion of a Tax Return. SpinCo shall provide to Holcim any transfer pricing documentation required to be prepared with respect to a Tax Return for any taxable period that begins on or before the second (2^nd) anniversary of the Distribution Date with respect to which SpinCo is the Preparing Party at least thirty (30) days prior to the finalization of such transfer pricing documentation, and Holcim shall be entitled to review and provide comments on such transfer pricing documentation (which documentation shall include, for the avoidance of doubt, the transfer pricing master file of SpinCo). SpinCo shall modify such transfer pricing documentation prior to its finalization to include Holcim’s reasonable comments.

3.4 Cooperation. The Parties shall provide, and shall cause their Affiliates to provide, assistance and cooperation to one another in accordance with Article VII with respect to the preparation and filing of Tax Returns, including providing information required to be provided under Article VIII and including, for the avoidance of doubt, cooperation with respect to the preparation for 2024 and 2025 of tax transparency reports, country-by-country reports, and any applicable Global Anti-Base Erosion Tax Returns. Notwithstanding anything to the contrary in this Agreement, Holcim shall not be required to disclose to SpinCo any consolidated, combined, unitary, or other similar Joint Return of which a member of the Holcim Group is the common parent or any information related to such a Joint Return other than information relating solely to the SpinCo Group; provided, however, that Holcim shall provide to SpinCo the transfer pricing master file of Holcim and its Subsidiaries for any taxable year ending prior to or including the Distribution Date. If an amended Separate Return for which SpinCo is responsible under this Article III is required to be filed as a result of an amendment made to a Joint Return pursuant to an audit adjustment, then the Parties shall cooperate to ensure that such amended Separate Return can be prepared and filed in a manner that preserves confidential information including through the use of third-party preparers.

3.5 Tax Reporting Practices. Except as provided in Section 3.6 or pursuant to a Final Determination, with respect to any Tax Return for any taxable period that begins on or before the second (2^nd) anniversary of the Distribution Date with respect to which SpinCo is the Responsible Party, such Tax Return shall be prepared in a manner (a) consistent with past practices, accounting methods and any similar standards, elections and conventions, including with respect to transfer pricing, used with respect to the Tax Returns in question (“Past Practices”) (unless there is no Reasonable Basis for the use of such Past Practices), 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), in accordance with reasonable Tax accounting practices selected by SpinCo; and (b) that, to the extent consistent with clause (a), takes into consideration the overall amount of Taxes due and payable on such Tax Return for all of the Parties by cooperating in making such elections or applications for group or other relief or allowances available in the taxing jurisdiction in which such Tax Return is filed. SpinCo shall not take any action inconsistent with the assumptions made (including with respect to any Tax Item) in determining all estimated or advance payments of Taxes on or prior to the Distribution Date. In addition, SpinCo (i) shall not be permitted, and shall not permit any member of the SpinCo Group, without Holcim’s prior written consent, to make a change in any of its methods of accounting for Tax purposes for any taxable period that begins on or before the second (2^nd) anniversary of the Distribution Date (unless there is no Reasonable Basis for not making such change), and (ii) shall notify Holcim of, and consider in good faith any reasonable comments provided by Holcim regarding, any such change in method of accounting for any taxable period that begins after the second (2^nd) anniversary of the Distribution Date and on or before the fifth (5^th) anniversary of the Distribution Date. Such notification and consideration described in clause (ii) of the preceding sentence shall occur prior to the making of any such change in method of accounting.

3.6 Reporting of the Transactions. Unless and until there has been a Final Determination to the contrary, each Party agrees not to take any position on any Tax Return, in connection with any Tax Contest, or otherwise that is inconsistent with (i) the Tax Materials, (ii) the Intended Tax Treatment, or (iii) the treatment of payments between the Holcim Group and the SpinCo Group as set forth in Section 5.4.

3.7 Payment of Taxes. 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.

3.8 Amended Returns and Carrybacks.

(a) SpinCo shall not, and shall not permit any member of the SpinCo Group to, file or allow to be filed any request for an Adjustment for any Pre-Distribution Period without the prior written consent of Holcim, such consent to be exercised in Holcim’s sole and absolute discretion, to the extent that any such request for Adjustment (i) directly relates to matters for which Holcim may have an indemnification obligation to SpinCo, or that may give rise to a refund to which ▇▇▇▇▇▇ would be entitled under this Agreement or (ii) would reasonably be expected to materially affect the Tax position of Holcim.

(b) Holcim shall not, and shall not permit any member of the Holcim Group to, file or allow to be filed any request for an Adjustment for any Pre-Distribution Period without the prior written consent of SpinCo, such consent to be exercised in SpinCo’s sole and absolute discretion, to the extent that any such request for Adjustment (i) directly relates to matters for which the SpinCo may have an indemnification obligation to Holcim, or that may give rise to a refund to which SpinCo would be entitled under this Agreement or (ii) would reasonably be expected to materially affect the Tax position of SpinCo.

(c) SpinCo shall, and shall cause each member of the SpinCo 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.

(d) SpinCo shall not, and shall cause each member of the SpinCo 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 Holcim’s sole and absolute discretion.

(e) Receipt of consent by SpinCo or a member of the SpinCo Group from Holcim pursuant to the provisions of this Section 3.8 shall not limit or modify SpinCo’s continuing indemnification obligation pursuant to Article V.

3.9 Tax Attributes. Upon written request by ▇▇▇▇▇▇, Holcim shall in good faith advise SpinCo in writing of the amount (if any) of any Tax Attributes which Holcim determines, in its sole and absolute discretion, shall be allocated or apportioned to any member of the SpinCo Group under applicable Tax Law. SpinCo and all members of the SpinCo Group shall prepare all Tax Returns in accordance with such written notice. SpinCo agrees that it shall not dispute any determination of Tax Attributes made by Holcim pursuant to this Section 3.9. Nothing in this Agreement shall require Holcim 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.

ARTICLE IV

(a) Holcim, on behalf of itself and all other members of the Holcim Group, hereby represents and warrants that (i) it has examined the Rulings, the Ruling Requests, the Tax Opinion, the Tax Certificates, the Internal Reorganization Plan, and any other materials delivered or deliverable in connection with the issuance of the Rulings and the rendering of the Tax Opinion, in each case, as they exist as of the date hereof (collectively, the “Tax Materials”), and (ii) the facts presented and representations made therein, to the extent descriptive of or otherwise relating to Holcim or any member of the Holcim Group or the Holcim Business, were or will be, at the time presented or represented and from such time until and including the Distribution Date, true, correct, and complete in all material respects. ▇▇▇▇▇▇, on behalf of itself and all other members of the Holcim Group, hereby confirms and agrees to comply with any and all covenants and agreements in the Tax Materials applicable to Holcim, any member of the Holcim Group, or the Holcim Business.

(b) SpinCo, on behalf of itself and all other members of the SpinCo Group, hereby represents and warrants that (i) it has examined the Tax Materials, and (ii) the facts presented and representations made therein, to the extent descriptive of or otherwise relating to SpinCo or any member of the SpinCo Group or the SpinCo Business, were or will be, at the time presented or represented and from such time until and including the Distribution Date, true, correct, and complete in all material respects. SpinCo, on behalf of itself and all other members of the SpinCo Group, hereby confirms and agrees to comply with any and all covenants and agreements in the Tax Materials applicable to SpinCo, any member of the SpinCo Group, or the SpinCo Business.

(c) Each of Holcim, on behalf of itself and all other members of the Holcim Group, and SpinCo, on behalf of itself and all other members of the SpinCo Group, represents and warrants that it knows of no fact or circumstance (after due inquiry) that may (i) cause the Transactions to fail to qualify for the Intended Tax Treatment or (ii) could adversely affect the issuance, effectiveness or validity of any Ruling.

(d) Each of Holcim on behalf of itself and all other members of the Holcim Group, and SpinCo, on behalf of itself and all other members of the SpinCo Group, represents and warrants that it has no plan or intention to take, fail to take, or cause or permit to be taken any action which is inconsistent with any of the statements or representations made or set forth in the Tax Materials or that may (i) cause the Transactions to fail to qualify for the Intended Tax Treatment or (ii) could adversely affect the issuance, effectiveness or validity of any Ruling.

(e) Each of the Parties hereby represents and warrants that it has the power and authority to execute, deliver and perform this Agreement, that this Agreement has been duly authorized by all necessary corporate action on the part of such Party, that this Agreement constitutes a legal, valid and binding obligation of each such Party enforceable against it in accordance with its terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium or other similar Laws affecting creditors’ rights generally and general equity principles.

4.2 Certain Restrictions Relating to the Intended Tax Treatment of the Transactions.

(a) SpinCo, on behalf of itself and all other members of the SpinCo Group, hereby covenants and agrees that no member of the SpinCo 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 an SpinCo Disqualifying Action.

(b) SpinCo:

(i) during the Restricted Period, shall continue, and cause to be continued, the active conduct of each SpinCo Trade or Business for purposes of Section 355(b)(2) of the Code, taking into account Section 355(b)(3) of the Code;

(ii) during the Restricted Period, shall not voluntarily dissolve or liquidate itself or any of its Affiliates (including any action that is a liquidation for U.S. federal income tax purposes);

(iii) during the Restricted Period, shall not (1) enter into any Proposed Acquisition Transaction or, to the extent SpinCo 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 SpinCo stock, or rights to acquire SpinCo 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 SpinCo Capital Stock (including through the conversion of any class of SpinCo Capital Stock into another class of SpinCo Capital Stock), or (4) 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 SpinCo 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 forty percent (40%) or greater interest in SpinCo (or in any Affiliate of SpinCo that was a party to an Internal Distribution) or otherwise jeopardize the Intended Tax Treatment;

(iv) during the Restricted Period, shall not, and shall not cause or permit any member of the SpinCo 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 gross assets of any SpinCo Trade or Business or more than twenty percent (20%) of the consolidated gross assets of SpinCo or the SpinCo 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 SpinCo or any member of the SpinCo Group. The percentages of gross assets or consolidated gross assets of SpinCo or the SpinCo 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 SpinCo and the members of the SpinCo Group as of the Distribution Date. For purposes of this Section 4.2(b)(iv), a merger of SpinCo or one of its Subsidiaries with and into any Person that is not a wholly owned Subsidiary of SpinCo shall constitute a disposition of all of the assets of SpinCo or such Subsidiary;

(v) during the Restricted Period, shall continue a business (including holding) activity in Switzerland at its legal seat in the canton of Zug comprising the holding, directly or indirectly, of more than 50% of the voting rights in at least one subsidiary that is engaged in active business operations, as indicated in the Swiss Tax Rulings;

(vi) during the Restricted Period, shall not merge or consolidate with any other Person, including any of its Affiliates (or cause or permit New Swiss IPCo or any Affiliate of SpinCo that was a party to an Internal Distribution to merge or consolidate with any other Person), as indicated in the Swiss Tax Rulings;

(vii) within 5 years of the Distribution, shall maintain at least three senior employees having their work place in Zug, Switzerland and shall ensure that at least 40% of its board meetings are normally physically held in Switzerland as indicated in the Swiss Tax Rulings; and

(viii) within 5 years of the Distribution, shall ensure that New Swiss IPCo respectively any Person to whom its business is transferred in any transaction other than arm’s-length transaction with an unrelated Person, remains subject to Tax in Switzerland, as indicated in the Swiss Tax Rulings.

(c) Notwithstanding the restrictions imposed by Section 4.2(b), SpinCo or a member of the SpinCo Group may take any of the actions or transactions described therein if SpinCo either (i) obtains a Tax ruling with an appropriate Taxing Authority or an Unqualified Tax Opinion, at the election of Holcim, in form and substance satisfactory to Holcim, or (ii) obtains the prior written consent of Holcim waiving the requirement that SpinCo obtain a Tax ruling or an Unqualified Tax Opinion, such waiver to be provided in ▇▇▇▇▇▇’s sole and absolute discretion. Holcim’s evaluation of a Tax ruling or 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 or ruling would be acceptable to Holcim). SpinCo shall bear all costs and expenses of securing any such Tax ruling or an Unqualified Tax Opinion and shall reimburse Holcim for all reasonable out-of-pocket expenses (including fees of external legal counsel and external Tax Advisors) that Holcim or any of its Affiliates may incur in good faith in seeking to obtain or evaluate any such Tax ruling or an Unqualified Tax Opinion. Neither the delivery of a Tax ruling or an Unqualified Tax Opinion nor ▇▇▇▇▇▇’s waiver of SpinCo’s obligation to deliver Tax ruling or an Unqualified Tax Opinion shall limit or modify SpinCo’s continuing indemnification obligation pursuant to Article V.

(d) The Parties each (i) shall timely file (or cause to be timely filed) any appropriate information and statements (including any Transaction Filings) to report the applicable steps of the Transactions as qualifying for the Intended Tax Treatment as foreseen in the Tax Rulings, and (ii) shall not (and shall not cause or permit any of their respective Affiliates to) take any position on any Tax Return, financial statement or other document (or otherwise with a Taxing Authority) that is inconsistent with such qualification.

ARTICLE V

INDEMNITY OBLIGATIONS

5.1 Indemnity Obligations. Notwithstanding anything to the contrary in this Agreement:

(a) Holcim shall indemnify and hold harmless SpinCo from and against, and will reimburse SpinCo for:

(i) all liability for Taxes allocated to Holcim pursuant to Article II (other than liabilities described in Section 5.1(b)(ii) and/or 5.1(b)(iii));

(ii) all Taxes and Tax-Related Losses arising out of, based upon, or relating or attributable to any breach of or inaccuracy in, or failure to perform, as applicable, any representation, covenant, or obligation of any member of the Holcim Group pursuant to this Agreement; and

(iii) any other amounts Holcim is required to pay to SpinCo pursuant to the terms of this Agreement.

(b) Without regard to whether a Tax ruling or an Unqualified Tax Opinion may have been provided or whether any action is permitted or consented to hereunder, SpinCo shall indemnify and hold harmless Holcim from and against, and will reimburse Holcim for:

(i) all liability for Taxes allocated to SpinCo pursuant to Article II;

(iii) any Taxes and Tax-Related Losses attributable to any SpinCo Disqualifying Action; and

(iv) any breach of Section 4.2, and

(v) any other amounts SpinCo is required to pay to Holcim pursuant to the terms of this Agreement.

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

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 (and shall include any relevant Tax Return, statement, bill or invoice relating to Taxes, costs, expenses or other amounts due and owing), 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 thirty (30) days after the receipt of notice from the other Party.

(b) If, as a result of any change or redetermination, any amount previously allocated to and borne by one Party pursuant to the provisions of Article II is thereafter allocated to the other Party, then, no later than thirty (30) days after such change or redetermination, such other Party shall pay to the first Party the amount previously borne by such Party which is allocated to such other Party as a result of such change or redetermination.

5.3 Payment Mechanics.

(a) All payments under this Agreement shall be made by Holcim directly to SpinCo and by SpinCo directly to Holcim; provided, however, that if the Parties mutually agree with respect to any such indemnification payment, any member of the Holcim Group, on the one hand, may make such indemnification payment to any member of the SpinCo 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).

5.4 Treatment of Payments. The Parties agree that any payment made between the Parties pursuant to this Agreement, unless otherwise required by Law or a Final Determination, 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 Holcim to SpinCo, or (ii) a distribution by SpinCo to Holcim, in each case, made immediately prior to the Distribution. Notwithstanding the foregoing, Holcim shall notify SpinCo if it determines that any payment made pursuant to this Agreement is to be treated, for any Tax purposes, in a different manner, including, but not limited to, 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. Any Tax indemnity payment made by a Party under this Agreement shall be increased as necessary so that after making all payments in respect of Taxes imposed on or attributable to such indemnity payment, the recipient Party receives an amount equal to the sum it would have received had no such Taxes been imposed, respectively decreased to take into account any Tax benefit actually realized by the Indemnitee resulting from the incurrence of the liability in respect of which the payment by the Indemnifying Party is made.

ARTICLE VI

TAX CONTESTS

6.1 Notice. Each Party shall notify the other Party in writing within ten (10) days after receipt by such Party or any member of its Group of a written communication from any Taxing Authority with respect to any pending or threatened audit, examination, claim, dispute, suit, action, proposed assessment, or other proceeding (a “Tax Contest”) concerning any Taxes for which the other Party may be liable pursuant to this Agreement and/or any Taxes in respect of payments between the Holcim Group and the SpinCo Group, and thereafter shall promptly forward or make available to such Party copies of notices and communications relating to such Tax Contest. 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 materially prejudiced by such failure.

6.2 Joint Returns. In the case of any Tax Contest with respect to any Joint Return, Holcim 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, subject to Sections 6.1 and 6.6; provided, that Holcim shall not 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 without the prior written consent of SpinCo if any such action would cause SpinCo to be liable for an amount of Taxes in excess of $1,000,000 pursuant to this Agreement or otherwise.

6.3 Separate Returns. Except as provided in Section 6.4, in the case of any Tax Contest with respect to a Separate Return, 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; provided that, in the case of any such Tax Contest that relates both to Taxes for which Holcim has liability pursuant to Section 2.1(a), and to Taxes for which SpinCo has liability pursuant to Section 2.1(b), (i) any Tax Contest that relates to the treatment of payments between the Holcim Group and the SpinCo Group shall be jointly controlled by the Parties, and (ii) in the case of any other Tax Contest described in this proviso, the Party that has the largest amount of potential Tax liability arising out of such Tax Contest shall be the Controlling Party and the other Party shall be the Non-Controlling Party (with the rights set forth in Sections 6.1 and 6.6); provided, further, that the Controlling Party in any Tax Contest described in clause (ii) of the preceding proviso shall not 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 without the prior written consent of the Non-Controlling Party if any such action would cause the Non-Controlling Party to be liable for an amount of Taxes in excess of $1,000,000 pursuant to this Agreement or otherwise.

6.4 Inter-Party Payments. In the case of any Tax Contest with respect to a Separate Return that that involves any Taxes identified on items (1) and (2) of Schedule 2.1(a)(v) in excess of $1,000,000, the Parties shall jointly control the prosecution of such Tax Contest, including the right to communicate with agents of the applicable Taxing Authority. Neither Party shall 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 without the prior written consent of the other Party.

6.5 Obligation of Continued Notice. 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 material increased costs or material prejudice to such other Party.

6.6 Tax Contest Cooperation 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 copies of any written materials relating to such potential adjustment in such Tax Contest received from any Taxing Authority, (iii) 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, (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, and (v) 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.

ARTICLE VII

COOPERATION

7.1 General.

(a) Each Party shall fully cooperate, and shall cause all members of such Party’s Group to fully cooperate and in a timely manner (considering the other Party’s normal internal processing or reporting requirements), with all reasonable requests in writing from the other Party, or from an agent, representative, or advisor of such Party, in connection with the preparation and filing of any Tax Return, claims for Refunds, the conduct of any Tax Contest, 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 either Party or any member of either Party’s Group covered by this Agreement and the establishment of any reserve required in connection with any financial reporting (a “Tax Matter”).

ARTICLE VIII

RETENTION OF RECORDS; ACCESS

8.1 Retention of Records. For so long as the contents thereof may become material in the administration of any matter under applicable Tax Law, but in any event until the later of (i) sixty (60) days after the expiration of any applicable statutes of limitation (including any waivers or extensions thereof), and (ii) ten (10) years after the Distribution Date, the Parties shall retain records, documents, accounting data, and other information (including computer data) necessary for the preparation and filing of all Tax Returns (collectively, “Tax Records”) in respect of Taxes of any member of either the Holcim Group or the SpinCo Group for any Pre-Distribution Period or Straddle Period or for any Tax Contests relating to such Tax Returns. At any time after the Distribution Date when the Holcim Group proposes to destroy any Tax Records, ▇▇▇▇▇▇ shall first notify SpinCo in writing, and the SpinCo Group shall be entitled to receive, at the cost and expense of the SpinCo Group, such records or documents proposed to be destroyed. At any time after the Distribution Date when the SpinCo Group proposes to destroy any Tax Records, SpinCo shall first notify Holcim in writing, and the Holcim Group shall be entitled to receive, at the cost and expense of the Holcim Group, such records or documents proposed to be destroyed. The Parties will notify each other in writing of any waivers or extensions of the applicable statute of limitations that may affect the period for which the foregoing records or other documents must be retained.

Each of the Parties shall permit the other Party and its 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 Party in connection with the preparation of Tax Returns or financial accounting statements, audits, litigation, or the resolution of items pursuant to this Agreement and subject to any security procedures reasonably required by the Party giving access to protect its information technology systems. The Party seeking access to the records of the other Party shall bear all out-of-pocket third-party costs and expenses associated with such access, including any professional fees.

ARTICLE IX

DISPUTE RESOLUTION

9.1 Dispute Resolution. The Parties acknowledge and agree that Article VIII of the Separation Agreement is hereby incorporated into this Agreement, and the procedures set forth therein shall apply, mutatis mutandis, to any dispute, controversy, or claim, arising out of or relating to this Agreement, including the breach, termination, or validity thereof (each a “Dispute”); provided, however, that Section 8.3 of the Separation Agreement shall not apply to any such Dispute. If any such Dispute has not been resolved in writing for any reason within the Negotiation Period, the Parties shall jointly appoint a nationally recognized independent public accounting firm (the “Accounting Firm”) to resolve such Dispute. If the Parties are unable to agree on an Accounting Firm in writing within fifteen (15) business days of the expiration of the Negotiation Period, the Accounting Firm shall be appointed, at the written request of any Party, by the ICC International Centre for ADR in accordance with the Rules for the Appointment of Experts and Neutrals of the International Chamber of Commerce. The Accounting Firm shall make determinations with respect to the Dispute based solely on representations made by Holcim, SpinCo, 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 Accounting Firm to resolve any Dispute no later than thirty (30) days after the submission of such Dispute to the Accounting 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. The Parties agree that all decisions by the Accounting Firm with respect thereto shall be final and conclusive and binding on the Parties absent manifest error or fraud. The Accounting 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 Holcim and its Subsidiaries, except as otherwise required by applicable Law. The Parties shall require the Accounting 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 Accounting Firm shall be borne equally by the Parties.

Subject to the preceding sentence, this Agreement is binding upon, inures to the benefit of and is enforceable by the Parties hereto and their respective successors and permitted assigns.

In the event of such termination, this Agreement shall become null and void and no Party, nor any of its officers, directors or employees, shall have any Liability to any other Party or any other Person.

Each of the Parties shall cause (or with respect to an Affiliate that is not a Subsidiary, shall use commercially reasonable efforts to cause) to be performed, and hereby guarantees the performance of, all actions, agreements and obligations set forth herein to be performed by any Subsidiary or Affiliate of such Party or by any Business Entity that becomes a Subsidiary or Affiliate of such Party on and after the Distribution. This Agreement is being entered into by Holcim and SpinCo on behalf of themselves and the members of their respective groups (the Holcim Group and the SpinCo Group). This Agreement shall constitute a direct obligation of each such entity and shall be deemed to have been readopted and affirmed on behalf of any Business Entity that becomes a Subsidiary or Affiliate of such Party on and after the Distribution. Either Party shall have the right, by giving notice to the other Party, to require that any Subsidiary of the other Party execute a counterpart to this Agreement to become bound by the provisions of this Agreement applicable to such Subsidiary.

10.15 Specific Performance. The Parties agree that irreparable damage, for which monetary damages (even if available) would not be an adequate remedy, would occur in the event that the provisions of this Agreement were not performed in accordance with their specific terms. Accordingly, it is hereby agreed that the Parties shall be entitled to an injunction, specific performance and other equitable relief to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof, in addition to any other remedy to which they are entitled in Law or equity.
