	(a)	at any meeting of securityholders of the Company (including in connection with any separate vote of any sub-group of securityholders of the Company that may be required to be held and of which sub-group the Securityholder forms part) called to vote upon the Arrangement or at any adjournment or postponement thereof or in any other circumstances upon which a vote, consent or other approval with respect to the Arrangement is sought, the Securityholder shall withhold its vote (or cause to be withheld) on all of its Subject Shares (which have a right to vote at such meeting) in respect of the Arrangement Resolution;

	(b)	The Purchaser and Rio Tinto agree that, for the purposes of the Private Proceedings only, and without prejudice to any other proceedings, including the US Class Action, the Purchaser and Rio Tinto shall be liable to satisfy any amount ordered to be paid to the Securityholders notwithstanding that the claims asserted and amounts ordered to be paid in the Private Proceedings are in respect of claims against Affiliates of Rio Tinto or the Purchaser, including the Company, that are not parties to this Agreement.

Schedule “B”

Dispute Resolution Process

The Securityholders, the Purchaser and Rio Tinto (the “DR Parties”) agree to resolve the Dissent Proceeding and the Oppression Claim confidentially in a dispute resolution procedure in accordance with the following terms:

The DR Parties agree that Warren Winkler will act as mediator to conduct an expedited mediation of the Private Proceedings (or, if Warren Winkler becomes unavailable, another mediator with experience in shareholder remedies and dissent rights will be appointed by mutual agreement of the DR Parties). The mediation shall be conducted in Toronto, Ontario, Canada.

The mediation will commence within 30 days of the Effective Date and be completed within 60 days of the Effective Date. Any party may opt out of the mediation at any time, upon which the mediation shall terminate.

The DR Parties will mediate and, if necessary, arbitrate (a) the fair value amount remaining to be paid, if any, by the Purchaser to the Securityholders to resolve the Dissent Proceeding, (b) the damages or compensation amount, if any, to be paid by the Purchaser or any of its Affiliates to the Securityholders to resolve the Oppression Claim.

No interest shall be payable to the Securityholders in respect of any amounts agreed or determined to be owing in relation to amounts in 3(a) or 3(b).

The costs of the mediator will be divided equally between the Purchaser on the one hand and the Securityholders on the other hand.

Absent resolution at mediation, any remaining issue or issues will be determined by confidential binding arbitration on a schedule to be determined by the arbitrator but which the DR Parties agree to use reasonable commercial efforts to complete within no more than 12 months of the last mediation date.

The DR Parties agree that Eleanore Cronk will act as arbitrator (or, if Eleanore Cronk becomes unavailable, another arbitrator with experience in shareholder remedies and dissent rights will be appointed by mutual agreement of the DR Parties or, failing such agreement, by application of any party to the Ontario Superior Court of Justice). The arbitration shall be conducted in Toronto, Ontario, Canada.

The costs of the arbitrator, and of the DR Parties in relation to the arbitration, will be divided equally between the Purchaser on the one hand and the Securityholders on the other hand.

The arbitrator shall have the jurisdiction to decide all matters of procedure, including all matters concerning disclosure and discovery obligations of the parties hereto and their respective Affiliates in the arbitration.

10.

All decisions of arbitrator to be final, binding and non-appealable.

- B-2 -

11.

The entirety of the foregoing dispute resolution procedure, including all discussions, submissions and determinations, shall remain confidential and may not be disclosed by any party except as required by applicable law.

12.

The DR Parties shall keep all information, documents, evidence, witness testimony or submissions obtained in the Private Proceedings (the “Confidential Information”) in strict confidence and shall use the Confidential Information solely for the purpose of the Private Proceedings and for no other purpose. The DR Parties will not disclose, directly or indirectly, any Confidential Information to any third party, except as may be agreed with the other DR Parties or pursuant to the terms of a protective order concerning discovery in the US Class Action. If any person or entity requests or attempts to compel disclosure Confidential Information from any DR Party, such DR Party shall promptly notify the other DR Parties. The Securityholders may not collaborate with any other shareholders of the Company on the Private Proceedings, except as may be agreed between the DR Parties or as may be ordered by the arbitrator in respect of any other shareholder who is party to a private confidential dispute resolution procedure substantially the same as the terms set out in this Schedule “B” and agreed to on the date hereof. For the avoidance of doubt and notwithstanding the foregoing, nothing in the clause shall restrict Rio Tinto or any of its Affiliates in the defence of the US Class Action.

13.

The only remedy for the Oppression Claim will be damages or other monetary compensation.

Schedule “C”

Press Release

(see attached)

Notice to ASX/LSE

17 November 2022

Update on Transaction with Turquoise Hill Resources

Rio Tinto has carefully considered the concerns raised by minority shareholders of Turquoise Hill Resources Ltd. (“Turquoise Hill”) in relation to the dissent and dispute resolution provisions in the agreements (the “Agreements”) it entered into with certain funds and other entities related to Pentwater Capital Management LP and SailingStone Capital Partners LLC (the “Named Securityholders”) that were previously announced on 1 November 2022. Rio Tinto in good faith has been negotiating with the Special Committee of Turquoise Hill on comparable provisions for other minority shareholders. However, notwithstanding the parties best efforts, those negotiations have been unsuccessful.

Rio Tinto has now agreed to terminate the Agreements with the Named Securityholders. While Rio Tinto’s proposed transaction to acquire, by way of a plan of arrangement (the “Arrangement”), the approximately 49% of the issued and outstanding shares of Turquoise Hill that Rio Tinto does not own for C$43.00 per share in cash (the “Proposed Transaction”) will proceed, there is no assurance that any of the Named Securityholders will continue to withhold their vote or whether any of them will vote for or against the Arrangement. Copies of the termination agreements are being publicly filed by Rio Tinto as part of its 13D amendment in the U.S.

All minority shareholders of Turquoise Hill will have access to the same dissent rights and statutory process through the Yukon Courts for Rio Tinto’s Proposed Transaction as described in Turquoise Hill’s circular dated 27 September 2022 (the “Circular”). To further support the Proposed Transaction, Rio Tinto irrevocably commits to:

•

Waive the 12.5% dissent condition in respect of the Arrangement, provided that Turquoise Hill shares for which dissent is validly exercised do not exceed 17.5% of Turquoise Hill shares outstanding;

•

Pay C$34.40 per share (the “Upfront Payment”) to any Turquoise Hill shareholder who validly dissents and elects to receive such amount (an “Electing Shareholder”), within two business days of the effective date of the Arrangement (the “Effective Date”);

•

Pay to an Electing Shareholder interest at the Canada 1 Year Treasury Bill Yield on any balance of “fair value” that becomes payable under the dissent process over and above the Upfront Payment up to C$43 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; and

•

Allow any oppression claims by any Turquoise Hill minority shareholders, including Electing Shareholders, against Turquoise Hill, Rio Tinto 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 Rio Tinto no later than seven days following the Effective Date.

Rio Tinto Copper Chief Executive Bold Baatar said: “We have acknowledged feedback received from minority shareholders and returned to the proposal originally unanimously recommended by the Turquoise Hill Special Committee. We will work with the Turquoise Hill Special Committee to secure a new shareholder meeting date so that the Proposed Transaction can be voted on by minority shareholders as soon as practicable. We continue to believe that a premium of 67% for their shares and removal of financial uncertainty is an attractive proposition for minority shareholders.”

Further details on the procedure to become an Electing Shareholder and how an oppression claim can be served on or provided to Turquoise Hill and Rio Tinto will be provided on or before 23 November 2022.

Rio Tinto confirms that there is no floor or minimum to the determination of “fair value” under any dissent proceedings and no assurance that dissenting shareholders will receive the full C$43.00 for their shares. The dissent process is a time consuming and lengthy process that introduces uncertainty in relation to the consideration to be received and the potential for substantial legal costs to the dissenting shareholder. Rio Tinto intends to vigorously defend all proceedings and claims. Additional details regarding the dissent process are described in the Circular. It is recommended that minority shareholders seek independent legal advice if they wish to exercise their dissent rights.

Rio Tinto is making the irrevocable commitments outlined above to all minority shareholders of Turquoise Hill. Rio Tinto confirms that it has no other agreement, commitment or understanding with any of the Named Securityholders as to how they will vote in respect of the Arrangement, whether they will continue to exercise their dissent rights, how any dissent proceedings or claims will be conducted or otherwise dealt with, or regarding any other matter.

As previously announced by Turquoise Hill, the Special Meeting of shareholders to vote on the Proposed Transaction has been postponed. Rio Tinto has requested the Turquoise Hill Special Committee to proceed with a shareholder meeting for the Arrangement as soon as possible.

The Proposed Transaction represents Rio Tinto’s best and final all-cash transaction price of C$43.00 per share, which provides Turquoise Hill minority shareholders the option to realise significant and immediate value. This represents a premium of 67% to Turquoise Hill’s closing price of C$25.68 per share on 11 March 2022, the day prior to Rio Tinto’s initial public proposal to acquire Turquoise Hill. Since 11 March 2022, publicly traded peer copper producer share prices have declined by 24%¹.

Rio Tinto is continuing to work towards the completion of the Proposed Transaction that will simplify governance, improve efficiency and create greater certainty of funding for the long-term success of the Oyu Tolgoi copper project.

Rio Tinto Canadian early warning disclosure
