2. Irrevocable Commitments

On November 17, 2022, Rio Tinto announced the termination of agreements entered into on November 1, 2022 (the “Named Shareholder Agreements”) between the Purchaser, the Parent and certain Shareholders of the Corporation related to the Pentwater Funds and SailingStone (collectively, the “Named Shareholders”) and certain Irrevocable Commitments (as defined below) made by Rio Tinto for the benefit of all Minority Shareholders. The Corporation was not a party to either the entry into or the termination of the Named Shareholder Agreements.

Pursuant to the Irrevocable Commitments, Rio Tinto has committed to do the following:

• (i) pay C$34.40 per Share (the “Upfront Payment”) to any Shareholder who validly exercises Dissent Rights and who, not later than two Business Days prior to the Effective Date, validly elects to receive such amount (an “Electing Shareholder”), which Upfront Payment will be paid within two Business Days of the Effective Date provided that all required materials are submitted by an Electing Shareholder in advance; and (ii) pay to an Electing Shareholder interest at an annual rate equal to the Canada 1 Year Treasury Bill Yield determined as of 5:00 p.m. (Montréal time) on the Effective Date on any balance of “fair value” that becomes payable under the dissent process over and above the Upfront Payment up to C$43.00 in fair value per Share calculated from the Effective Date to the date of payment, provided that no other interest shall be payable to an Electing Shareholder in respect of any fair value payment (collectively, the “Dissent Payment Election”); and

• allow any oppression claims by any Minority Shareholder against Turquoise Hill, the Parent or their respective affiliates to survive the Arrangement and be pursued following the Effective Date, where such claims are served on or provided to Turquoise Hill and the Parent no later than seven days following the Effective Date;

(collectively, the “Irrevocable Commitments”).

Under the dissent procedures, there is no floor or minimum to the determination of “fair value” and no assurance of the amount that Dissenting Shareholders will receive for their Shares.

On November 24, 2022, the Corporation, the Purchaser and the Parent entered into an amendment to the Arrangement Agreement (the “Arrangement Agreement Amendment”) in order to amend the plan of arrangement to give effect to the Irrevocable Commitments (as so amended, the “Amended Plan of Arrangement”). As a result, if the Arrangement is completed, Rio Tinto will be obligated to comply with the Irrevocable Commitments pursuant to the Final Order.

In addition, pursuant to the Arrangement Agreement Amendment:

• the dissent closing condition in the Arrangement Agreement was amended to increase the threshold for Shares for which Dissent Rights are validly exercised from 12.5% to 17.5%; and

• the Purchaser and the Parent each represented to the Corporation that, prior to the Effective Date, without the prior written consent of the Corporation or except for the payment to a Dissenting Shareholder of C$43.00 for some or all of the Shares held by such Dissenting Shareholder, they will not enter into any contracts, undertakings, commitments, arrangements or understandings with any Shareholder, member of management or member of the Board relating to Turquoise Hill’s securities, the Arrangement or the Arrangement Resolution.

8. Dissenting Shareholders’ Rights

The following supplements the information set out under the heading “Dissenting Shareholders’ Rights” in the Circular.

An election form (the “Dissent Election Form”) pursuant to which a Dissenting Shareholder may make the Dissent Payment Election is available on the Corporation’s profiles on SEDAR at www.sedar.com and EDGAR at www.sec.gov and on the Corporation’s website. In order to make the Dissent Payment Election, a fully completed Dissent Election Form must be submitted to the Depositary in accordance with the instructions set out therein by no later than 5:00 p.m. (Montréal time) on December 14, 2022.

Prior to the Effective Date, any beneficial owner of Shares who has properly exercised Dissent Rights by causing its Intermediary to cause dissent rights to be exercised on such beneficial owner’s behalf must transfer such Shares into registered form. Any Shareholder who needs assistance in completing this process may contact the Corporation’s proxy solicitation agent and strategic shareholder advisor, Kingsdale Advisors, at 1-888-370-3955 (toll-free in North America), or by calling collect at 416-867- 2272 (outside of North America) or by email at contactus@kingsdaleadvisors.com.

A Dissenting Shareholder may withdraw its dissent at any time in advance of the Effective Time by way of written notice to the Corporation.

9. Background to the Irrevocable Commitments

The following supplements the information set out under the heading “Special Factors – Background to the Arrangement” with information related to the events that led to the Irrevocable Commitments that followed the date of the Circular.

On the evening of Sunday, October 30, 2022, the Special Committee was first advised that Rio Tinto was in negotiations with the Named Shareholders to enter into the Named Shareholder Agreements pursuant to which Rio Tinto and the Named Shareholders would agree to private resolution of their dissent rights and asserted oppression claims in exchange for the Named Shareholders withholding their votes in connection with the Arrangement (i.e., not voting for or against the Arrangement).

In advance of the execution of the Named Shareholder Agreements, the Special Committee expressed concern to Rio Tinto regarding the differential treatment of Minority Shareholders resulting from the Named Shareholder Agreements and suggested to Rio Tinto that it provide terms comparable to those in the Named Shareholder Agreements to all Minority Shareholders. Rio Tinto advised that it would not make the terms of the Named Shareholder Agreements available to all Minority Shareholders. The Special Committee also expressed its concern to Rio Tinto that, in light of the pending announcement of the Named Shareholder Agreements, Minority Shareholders would need additional time in advance of the Meeting to consider new information related to the Named Shareholder Agreements. In response to the concern of the Special Committee, Rio Tinto requested that the Corporation postpone the Meeting then scheduled for November 1, 2022 to November 8, 2022. The postponement was also intended to provide Rio Tinto and the Special Committee with additional time to consider whether terms comparable to those in the Named Shareholder Agreements could be offered to all Minority Shareholders.

On November 1, 2022, the Purchaser and the Parent entered into the Named Shareholder Agreements with the Named Shareholders. Turquoise Hill was not a party to the Named Shareholder Agreements and neither it nor the Special Committee was involved in negotiating the Named Shareholder Agreements. The final Named Shareholder Agreements contained terms whereby:

• the Named Shareholders agreed to withhold their votes on the Arrangement Resolution and revoke any prior proxy that would be inconsistent with that position;

• the Named Shareholders would exercise Dissent Rights;

• proceedings in respect of the Named Shareholders’ Dissent Rights in connection with the Arrangement, as well as certain oppression claims against Rio Tinto and its affiliates (the “Oppression Claims”), would be conducted in accordance with procedures set out in the Named Shareholder Agreements, which included mediation to be completed within 60 days of closing of the Arrangement and, absent resolution at mediation, confidential binding arbitration which the parties agreed to use reasonable commercial efforts to complete within 12 months of the conclusion of the mediation;

• the Named Shareholders would receive 80% of the Consideration within two Business Days of the Effective Date and 20% of the Consideration, plus interest thereon, within two Business Days of final determination of the dissent procedures set out in the Named Shareholder Agreements;

• the Purchaser, the Parent and the Named Shareholders would enter into mediation and, if necessary, arbitration of the fair value amount remaining to be paid, if any, by Rio Tinto to the Named Shareholders to resolve the dissent proceedings and the damages or compensation amount, if any, to be paid by Rio Tinto to the Named Shareholders to resolve the Oppression Claims;

• Rio Tinto would waive the closing condition in the Arrangement Agreement relating to the exercise of Dissent Rights to allow the Arrangement to be completed in circumstances where holders of up to 17.5% of the Shares validly exercise Dissent Rights; and

• the Named Shareholders provided covenants related to non-disparagement, non-interference and a release of all claims against the Purchaser, the Parent, the Corporation and their respective affiliates and past, present or future directors, officers or employees other than obligations under the Named Shareholder Agreements, claims related to the dissent proceedings and Oppression Claims and claims related to the U.S. securities law class action proceeding against Rio Tinto in the Southern District of New York.

Following the public announcement of the Named Shareholder Agreements, the Corporation and the Special Committee received a number of complaints from Minority Shareholders and inquiries from securities regulators, including the Autorité des marchés financiers (the “AMF”), regarding the Named Shareholder Agreements.

In the days that followed, counsel to the Special Committee engaged with counsel to Rio Tinto in order to seek to address the differential treatment of Minority Shareholders resulting from the Named Shareholder Agreements and engaged in discussions with securities regulators, including the AMF, regarding the Named Shareholder Agreements. To allow the Special Committee and Rio Tinto time to continue their discussions and in response to requests from the AMF, on November 6, 2022, at Rio Tinto’s request, the Corporation announced a further postponement of the Meeting to November 15, 2022. Subsequent to this announcement, counsel to the Special Committee and counsel to Rio Tinto continued to discuss a framework for providing terms comparable to those provided in the Named Shareholder Agreements to all Minority Shareholders. Following several further discussions regarding the Named Shareholder Agreements, the AMF advised the Corporation that, in light of the Named Shareholder Agreements, the AMF considered the transaction as then structured to raise public interest concerns. On November 9, 2022, the Corporation announced a further postponement of the Meeting to a date to be determined while the Special Committee continued to engage with Rio Tinto to address the impact of the Named Shareholder Agreements and seek to provide comparable terms to all Minority Shareholders.

On November 17, 2022, Rio Tinto announced that it and the Named Shareholders had agreed to terminate the Named Shareholder Agreements and that Rio Tinto would be providing the Irrevocable Commitments to all Minority Shareholders. As a result of the termination of the Named Shareholder Agreements and the provision of the Irrevocable Commitments to all Minority Shareholders, none of the Named Shareholders are receiving any “collateral benefit” (as such term is defined in MI 61-101) in connection with the Arrangement. In addition, as a result of the termination of the Named Shareholder Agreements, there is no assurance that any of the Named Shareholders will abstain from the vote on the Arrangement or vote for or against the Arrangement.

10. Recommendation of the Special Committee and the Board

The following supplements the information set out under the headings “Special Factors – Position of Turquoise Hill as to Fairness of the Arrangement – Recommendation of the Special Committee” and “Special Factors – Recommendation of the Board” in the Circular.

The Special Committee carefully considered, among other things (i) the termination of the Named Shareholder Agreements; (ii) the fact that all Minority Shareholders will have equal economic and procedural Dissent Rights as provided under Section 193 of the YBCA, as modified by the Amended Plan of Arrangement and the Amended Interim Order (as defined below); (iii) the fact that all Minority Shareholders will be entitled, at their option, to rely on the Irrevocable Commitments as set out in the Amended Plan of Arrangement; (iv) the incremental benefit of the Upfront Payment to Dissenting Shareholders in dispelling uncertainty and saving certain court-related costs and fees as compared to a Dissenting Shareholder availing itself of rights under Section 193 of the YBCA to apply to the Court for an order to receive an interim payment for all or part of the sum offered for their Shares in advance of the conclusion of their dissent proceedings; and (v) that the Dissent Payment Election is available to all Dissenting Shareholders, whether they vote against or abstain from voting on the Arrangement Resolution.

Based on the foregoing, the Special Committee determined that the Irrevocable Commitments do not negatively impact or change any of the reasons or factors considered by the Special Committee in making its original determination as to the fairness of the Arrangement to Minority Shareholders and recommendation to the Board in connection with the Arrangement, which are set out in the Circular under the heading “Special Factors – Position of Turquoise Hill as to Fairness of the Arrangement – Reasons for the Recommendation” (the “Original Reasons”). As a result and having regard to the Original Reasons as supplemented by the foregoing, the Special Committee unanimously determined that the Arrangement continues to be in the best interests of the Corporation and fair to Minority Shareholders, including unaffiliated securityholders of the Corporation, and unanimously recommended that the Board continue to recommend that Minority Shareholders vote in favour of the Arrangement Resolution.

On the unanimous recommendation of the Special Committee, the Board (with conflicted directors having recused themselves) unanimously determined that the Arrangement continues to be in the best interests of the Corporation and fair to the Minority Shareholders, including unaffiliated security holders of the Corporation, and continues to recommend that the Minority Shareholders vote in favour of the Arrangement Resolution.

11. Position of Rio Tinto as to the Fairness of the Arrangement

Rio Tinto has indicated in the amendment filed on November 21, 2022 (the “13E-3 Amendment”) to the Corporation’s Rule 13e-3 Transaction Statement on Schedule 13E-3 (the “Schedule 13E-3”) the following information, which supplements the information set out under the heading “Special Factors – Position of Rio Tinto as to the Fairness of the Arrangement” in the Circular.

A primary reason for the Purchaser and the Parent to enter into the Named Shareholder Agreements was to permit the Purchaser, the Parent and the Named Shareholders to resolve the dissent proceedings with respect to such Named Shareholders pursuant to a timely, private and confidential dispute resolution process and to reduce the resources that the Purchaser and the Parent would require to resolve these matters following the consummation of the Arrangement, which the Purchaser and the Parent believed would allow them to better support the Corporation’s significant financing needs and to work more effectively with Erdenes in a stronger partnership to realize the full potential of Oyu Tolgoi.

However, based on feedback from Minority Shareholders and securities regulators, and in order to ensure that all such Minority Shareholders have equal economic and procedural entitlements regarding Dissent Rights, without hindering their ability to undertake the dissent process provided for under Section 193 of the YBCA, as modified by the Amended Interim Order and the Amended Plan of Arrangement, the Purchaser and the Parent determined to terminate the Named Shareholder Agreements. A primary reason for the Purchaser and the Parent to terminate the Named Shareholder Agreements and to undertake to provide the Irrevocable Commitments is to provide equal treatment of all Minority Shareholders on the terms set out in the Irrevocable Commitments.

12. Certain Effects of the Arrangement

Rio Tinto has indicated in the 13E-3 Amendment the following information, which supplements the information set out under the heading “Special Factors – Certain Effects of the Arrangement” in the Circular.

Benefits of the Irrevocable Commitments to Minority Shareholders

A primary benefit of the termination of the Named Shareholder Agreements to all Minority Shareholders is that all Minority Shareholders, including the Named Shareholders, have equal economic and procedural Dissent Rights and the opportunity to benefit from the Irrevocable Commitments. As a whole, the Irrevocable Commitments offer benefits to all Minority Shareholders that were not previously available under the terms of the Arrangement.

Detriments of the Irrevocable Commitments to Minority Shareholders

A primary detriment for Electing Shareholders is that they will forego any right to receive interest on the fair value amount above C$43.00 per share remaining to be paid, if any, following the conclusion of the applicable dissent proceedings (or any settlement thereof).

The Parent has indicated that it intends to vigorously defend any dissent proceedings. There is therefore no assurance that Dissenting Shareholders will receive the full amount of the Consideration or more in the aggregate for their Shares.

13. Fairness of the Transaction

Rio Tinto has indicated in the 13E-3 Amendment the following information, which supplements the information set out under the heading “Special Factors – Position of Rio Tinto as to the Fairness of the Arrangement” in the Circular.

The termination of the Named Shareholder Agreements does not in any way affect the rights or ability of any Minority Shareholder (including the Named Shareholders) to receive the Consideration upon consummation of the Arrangement or to exercise Dissent Rights under Section 193 of the YBCA, as modified by the Amended Interim Order and the Amended Plan of Arrangement, in accordance with the terms described in the Circular, as supplemented by the information contained herein. All Minority Shareholders, including the Named Shareholders, are entitled, at their option, to utilize the Irrevocable Commitments.

The Purchaser and the Parent, after taking into consideration the termination of the Named Shareholder Agreements, together with additional rights available to Minority Shareholders contemplated by the Irrevocable Commitments, do not believe that the termination of the Named Shareholder Agreements or the rights contemplated by the Irrevocable Commitments negatively affect any of the reasons or factors considered by the Purchaser or the Parent in evaluating the fairness of the Arrangement to the Corporation’s unaffiliated security holders, each as described in the Circular. Instead, the Purchaser and the Parent believe the Irrevocable Commitments provide Minority Shareholders with additional entitlements not previously contemplated and which collectively enhance the fairness of the Arrangement to the Minority Shareholders. The Purchaser and the Parent continue to believe that the Arrangement is fair to the Corporation’s unaffiliated security holders, including both the Named Shareholders and the Minority Shareholders, for the reasons set forth in the Circular and the Schedule 13E-3, as amended.

ORDER AMENDING THE INTERIM ORDER

On November 24, 2022, the Court issued an Order amending the Interim Order (as so amended, the “Amended Interim Order”) to confirm the Record Date for the Meeting and amend certain dates set out in the Circular to reflect the change of the date of the Meeting, as set out above.

A copy of the Amending Order is annexed hereto as Appendix B.

NO OTHER AMENDMENTS TO CIRCULAR

Other than as set out in this Supplement, the Circular remains in full force and effect, unamended.
