[28] Holcim shall indemnify the Divestiture Trustee and hold the Divestiture Trustee harmless against any losses, claims, damages, liabilities or expenses arising out of, or in connection with, the performance of the Divestiture Trustee's duties, including all reasonable fees of counsel and other expenses incurred in connection with the preparation or defence of any claim, whether or not resulting in any liability, except to the extent that such losses, claims, damages, liabilities, or expenses result from malfeasance, gross negligence or bad faith by the Divestiture Trustee.

[29] Holcim shall indemnify the Commissioner and hold the Commissioner harmless against any losses, claims, damages, liabilities or expenses arising out of, or in connection with, the performance of the Divestiture Trustee's duties, including all reasonable fees of counsel and other expenses incurred in connection with the preparation or defence of any claim, whether or not resulting in any liability.

[30] If the Commissioner determines that the Divestiture Trustee has ceased to act or has failed to act diligently, the Commissioner may remove the Divestiture Trustee and appoint a substitute Divestiture Trustee.

[31] Holcim may require the Divestiture Trustee and each of the Divestiture Trustee’s consultants, accountants, legal counsel, investment bankers, business brokers, appraisers, and other representatives and assistants to sign an appropriate confidentiality agreement in a form satisfactory to the Commissioner only; provided, however, that such agreement shall not restrict the Divestiture Trustee from providing any information to the Commissioner.

[33] Notwithstanding any term of this Agreement, the obligations and powers of the Divestiture Trustee under this Agreement shall not expire until the Divestiture is completed.

VI. THIRD PARTY CONSENTS [34] To the extent that a Divestiture Agreement involves or will involve the sale or transfer of assets to a Purchaser, it shall be a condition in any such Divestiture Agreement (whether negotiated by Holcim or by the Divestiture Trustee) that Holcim shall, as a condition of closing, obtain any consents and waivers from Third Parties that are necessary to permit the assignment to, and assumption by, a Purchaser of all Material Contracts, Approvals and Authorizations relating to the Divestiture Assets; provided, however, that Holcim may satisfy this requirement by certifying that the Purchaser has executed agreements directly with one or more Third Parties which make such assignment and assumption unnecessary.

VII. NORTH AMERICAN SHARED SERVICES AND TRANSITIONAL SERVICES AGREEMENT

[35] Notwithstanding anything else in this Agreement, Holcim and Lafarge may enter into a Transitional Services Agreement with the Purchaser of the Divested Business in respect of the provision of the following back office and information technology services to commence upon Closing, if the Commissioner has approved the Transitional Services Agreement: accounting, human resources, information technology systems, order processing and vendor support services.

[36] At least 30 days prior to Closing, Holcim will provide the Commissioner with a draft of the proposed Transitional Services Agreement. Within 5 Business Days after receipt of the proposed Transitional Services Agreement, the Commissioner shall advise Holcim whether or not he approves the terms of the proposed agreement.

[37] Under the Transitional Services Agreement, NASS Personnel may provide such back office and information technology services as contemplated in Paragraph 35 to the Divested Business for a period of up to 12 months from the date on which the Purchaser acquires the Divested Business.

[38] Holcim shall develop, implement and monitor a system of access and data controls to prevent the unauthorized access or use of Confidential Information by NASS Personnel who perform services under the Transitional Services Agreement.

[39] The Transitional Services Agreement shall include terms requiring: 18

PUBLIC VERSION (a) Holcim to ensure compliance with the Transitional Services Agreement by NASS Personnel and enforce compliance with appropriate remedial action in the event of non-compliant access or use of Confidential Information by any NASS Personnel;

(b) Holcim to immediately notify the Monitor (or if there is no Monitor, the Commissioner) in the event of non-compliant access or use of Confidential Information by any NASS Personnel;

(c) Holcim to identify to the Commissioner any NASS Personnel and their positions or functions who access Confidential Information in performing services under the Transitional Services Agreement; and

(d) Any NASS Personnel who will be accessing Confidential Information under the Transitional Services Agreement to sign a statement confirming that he or she undertakes not to share any Confidential Information respecting the Divested Business with any of Holcim’s Continuing Employees.

[40] Holcim agrees to provide copies of all statements signed by NASS employees as contemplated in Paragraph 39(d) to the Monitor (or if there is no Monitor, the Commissioner).

VIII. EMPLOYEES [41] To the extent that a Divestiture Agreement involves or will involve the sale or transfer of assets to a Purchaser, Holcim (during the Initial Sale Period), the Divestiture Trustee (during the Divestiture Trustee Sale Period) and the Hold Separate Manager (for the Hold Separate Employees) shall provide to any prospective Purchaser and to the Commissioner information relating to the employees whose responsibilities involve the operation of the Divestiture Assets (including the Hold Separate Assets), to enable such Purchaser to make decisions regarding offers of employment to such employees. The Monitor shall review the information provided to ensure that it is sufficient to enable the Purchaser to make such decisions. Holcim shall:

(a) not interfere, directly or indirectly, with any negotiations by a Purchaser to employ any such employees;

(b) not offer any incentive to such employees to decline employment with the Purchaser or to accept other employment with Holcim;

(c) remove any impediment that may deter such employees from accepting employment with the Purchaser;

(d) waive any non-compete or confidentiality provisions of employment or other contracts that could impair the ability of such employees to be employed by the Purchaser; and

19

PUBLIC VERSION (e) pay or transfer to or maintain for such employees subsequently employed by Purchaser all current and accrued bonuses, pensions and other current and accrued benefits to which such employees would otherwise have been entitled had they remained in the employment of Holcim.

[42] For a period of 1 year following completion of the Divestiture, Holcim shall not, without the prior written consent of the Commissioner, directly or indirectly solicit or employ any Persons employed in connection with the Divestiture Assets who have accepted an offer of employment with the Purchaser unless such Person’s employment has been terminated by the Purchaser. However, this Section does not apply to any Person who responds to any general solicitation or advertisement not specifically directed at such Person or employees of the Divestiture Assets.

[43] Notwithstanding the provisions of this Part VIII, in the event that Holcim’s compliance with this Part VIII would otherwise constitute a breach of its obligations under a collective bargaining agreement to which it is a party, its compliance with the terms of such collective bargaining agreement will be deemed not to constitute a breach of this Part VIII, provided that, if such a circumstance arises, Holcim shall:

(a) notify the Commissioner within 3 Business Days of the exercise of the collective bargaining right leading to the conflict between compliance with this Part VIII and the collective bargaining agreement; and

(b) within 10 Business Days of giving notice under Paragraph 43(a), take such action as is reasonably necessary and practicable to address the impact that compliance with its obligations under the relevant collective bargaining agreement has on the viability, marketability and competitiveness of one or more of the Divestiture Assets up to the time of the completion of the associated Divestiture.

IX. FAILURE OF DIVESTITURE TRUSTEE SALE [44] If, by the end of the Divestiture Trustee Sale Period, the Divestiture has not been completed, or if the Commissioner is of the opinion that the Divestiture likely will not be completed prior to the end of the Divestiture Trustee Sale Period, the Commissioner may apply to the Tribunal, at his election, for either (i) such order as is necessary to complete the Divestiture; or (ii) such order as is necessary to ensure that the Transaction is not likely to prevent or lessen competition substantially.

X. MONITOR [45] The Commissioner shall appoint a Monitor, responsible for monitoring compliance by Holcim with this Agreement and any Transitional Services Agreement. Such appointment may occur at any time following registration of this Agreement. A reference in this Agreement to specific monitoring functions or tasks that are to be undertaken by the Monitor shall in no way detract from the

20

PUBLIC VERSION Monitor’s general power and duty to monitor all aspects of Holcim’s compliance with this Agreement.

[46] Within 5 Business Days after the appointment of the Monitor, Holcim shall submit to the Commissioner for approval the terms of a proposed Monitor Agreement with the Monitor and the Commissioner that transfers to the Monitor all rights and powers necessary to permit the Monitor to monitor compliance by Holcim with this Agreement.

[57] Holcim shall indemnify the Commissioner and hold the Commissioner harmless against any losses, claims, damages, liabilities or expenses arising out of, or in connection with, the performance of the Monitor's duties, including all reasonable fees of counsel and other expenses incurred in connection with the preparation or defence of any claim, whether or not resulting in any liability.

[62] Holcim shall not, for a period of 5 years after the date when the Divestiture is completed, directly or indirectly acquire any interest in the Divestiture Assets without the prior written approval of the Commissioner.
