Item 4. Purpose of Transaction

Item 4 of the Schedule 13D is hereby amended and supplemented as follows:

On April 9, 2021, RTIH entered into a Heads of Agreement with the Company (the “HoA”) providing for an updated funding plan (the “Funding Plan”) for the completion of the Company’s Oyu Tolgoi (OT) Underground Project in Mongolia (the “Project”). The Funding Plan in the HoA addresses an estimated remaining funding requirement of approximately US$2.3 billion (the “Anticipated Funding Shortfall”). The Anticipated Funding Shortfall is based on the terms of the HoA and current anticipated copper prices, among other factors, and does not include funding, if any, which may become required for a power plant.

The Funding Plan reflected in the HoA replace the arrangements established in the Memorandum of Understanding, dated September 9, 2020, between RTIH and the Company.

Under the HoA, subject to securing approval by OT LLC, the entity holding the Project and any required support from the Government of Mongolia, and subject to timing, availability, and terms and conditions being acceptable to RTIH and the Company, (1) a subsidiary of RTIH will engage with lenders to negotiate (a) a re-profiling of the existing financing arrangements for the Projects to, among other things, reduce the Anticipated Funding Shortfall by up to US1.4 billion; and (b) up to US$500 million in senior supplemental debt (SSD) under the existing financing arrangements from the Project; (2) RTIH has committed to address shortfalls from the re-profiling and additional SSD of up to US$750 million by providing a senior co-lending facility (the “Co-Lending Facility”) on the same terms as the existing financing arrangements from the Project; and (3) the Company committed to complete a rights offering or placement of Shares for up to US$500 million to satisfy any remaining funding shortfall within six months of the Co-Lending Facility becoming available.

The foregoing description of the HoA is not complete and is qualified in its entirety by reference to the HoA, which is attached as Exhibit A hereto and incorporated by reference herein.

Item 5. Interest in Securities of the Issuer

Item 5 of the Schedule 13D is hereby amended and restated in its entirety as follows:

Rio Tinto beneficially owns 102,196,643 Shares, representing 50.8 percent of the outstanding Shares.

Exhibit A

HEADS OF AGREEMENT

THIS HEADS OF AGREEMENT (THIS “AGREEMENT”) IS MADE ON AND AS OF APRIL 9, 2021 BETWEEN TURQUOISE HILL RESOURCES LTD. (“TRQ”) AND RIO TINTO INTERNATIONAL HOLDINGS LIMITED (“RTIHL”).

Recitals

As stated in TRQ’s annual management’s discussion and analysis for its financial year ended December 31, 2020, it was estimated that there is a base case incremental funding requirement of approximately US$2.3 billion in order to complete the development of the OT Project (the “Anticipated Funding Shortfall”).

B.	In order to ensure the continued funding and timely development of the OT Project, the parties have entered into this Agreement to, among other things, provide for their agreed funding plan that is intended to address the Anticipated Funding Shortfall, the principal components of which are:

(i)

up to approximately US$1.4 billion from the re-profiling of the existing OT Project Financing;

(ii)

up to US$500 million from additional A Loans at OT LLC;

(iii)

up to US$750 million from a co-lending by a member of the Rio Tinto Group to OT LLC under the OT Project Financing to address any deficiencies in the aggregate of (i) or (ii) above; and

(iv)

up to US$500 million from an equity offering by TRQ,

all on the terms set forth herein.

The parties reaffirm their desire for cooperation and alignment to enable the successful delivery of the OT Project. This agreement further paves the way for collaborative and proactive engagement with the Government of Mongolia (“GOM”) and the Parliamentary Working Group to resolve the concerns of GOM with the OT Project.

NOW THEREFORE, in consideration of the mutual covenants and agreements herein contained, TRQ and RTIHL agree as follows:

Defined Terms

1.	In this Agreement, certain capitalized terms used herein (including in the recitals hereto) are defined in Schedule A.

2.	This Agreement shall be interpreted in accordance with the rules set out in Schedule B.

OT Project Financing

Re-profiling. The parties desire the Rio Tinto Manager to engage with the Senior Lenders to negotiate a re-profiling of the Senior Loans, by way of an amendment to the existing OT Project Financing Agreements, to reduce the Anticipated Funding Shortfall by up to approximately US$1.4 billion and to ensure better alignment of the existing OT Project Financing with the Updated OT Project Mine Plan (the “Re-profiling”), and RTIHL shall cause the Rio Tinto Manager to undertake such negotiations and discussions regarding the Re-profiling as contemplated by Sections 7 and 8.

Additional A Loans. The parties desire the Rio Tinto Manager to engage with the IFI Lenders to negotiate up to US$500 million (in aggregate) of one or more additional A Loans under the OT Project Financing to be provided by one or more such IFI Lenders on the same terms and conditions as the existing A Loans as such may be amended by the Re-profiling (the “Additional A Loans”), and RTIHL shall cause the Rio Tinto Manager to undertake such negotiations and discussions regarding the Additional A Loans as contemplated by Sections 7 and 8.

5.	Scope. The parties desire the Re-profiling and Additional A Loans to include the specific terms listed in the Disclosure Letter.

Replacement B Loans and MIGA Loans. If necessary to replace any Senior Lender who does not want to participate in the Re-profiling, the parties agree that new B Loans and/or MIGA Loans may be obtained by OT LLC from existing or new Senior Lenders to replace existing B Loans and/or MIGA Loans, provided that the aggregate principal amount of B Loans and MIGA Loans is not increased above those principal amounts for B Loans and MIGA Loans set out in Schedule F. If necessary in accordance with the foregoing, RTIHL shall cause the Rio Tinto Manager to undertake such negotiations and discussions regarding the replacement B Loans and/or MIGA Loans as contemplated by Sections 7 and 8. For purposes of this Agreement, any reference to the Re-profiling includes any replacement B Loans and/or MIGA Loans pursuant to this Section 6.

Negotiations. The parties agree that the Rio Tinto Manager, with the assistance of the treasury group of Rio Tinto, shall lead the process and negotiations for the Re-profiling and Additional A Loans with the Senior Lenders and IFI Lenders with support from and consultation with TRQ and OT. TRQ, as provider of the TRQ DSU, and Rio Tinto, as provider of the Rio Tinto CSU, may participate in such discussions with the Senior Lenders and IFI Lenders and RTIHL shall cause the Rio Tinto Manager to use its reasonable commercial efforts to enable TRQ to participate in such discussions.

Timing. Each of the parties shall use its reasonable commercial efforts to cause the Re-Profiling and Additional A Loans to be negotiated and secured, and the conditions for the Re-profiling and Additional A Loans in Schedule C within its control to be satisfied, no later than the Outside Date, provided that (i) the parties shall first obtain the approval of the OT LLC board to commence negotiations for the Re-profiling, the Additional A Loans and the Co-Lending and (ii) the Rio Tinto Manager, in consultation with TRQ and Rio Tinto, shall be entitled to make all material determinations with respect to timing and strategy for such negotiations, having regard to the status of discussions with GOM and other factors. In addition to and on a parallel track with the foregoing, each of the parties shall use its reasonable commercial efforts to seek and obtain the approval of the OT LLC board to the final terms of the Re-profiling, the Additional A Loans and the Co-Lending, as may be required and as applicable. The Rio Tinto Manager shall prepare an information package on the Re-profiling and Additional A Loans for distribution to the Senior Lenders and IFI Lenders. If for any reason the Re-profiling and the Additional A Loans are not secured by the Outside Date, either party may withdraw from the process for the Re-profiling and Additional A Loans in which case both parties shall have no further obligations in respect of Sections 3 to 12. For greater certainty, a withdrawal by either party from the Re-profiling and Additional A Loan process in accordance with the foregoing shall not relieve (x) the Rio Tinto Lender of its Co-Lending commitment set forth in Sections 13 to 18 or otherwise affect such Co-Lending commitment or (y) TRQ of its Equity Offering commitment set forth in Sections 19 to 23 or otherwise affect such Equity Offering commitment.

9.	Approvals. The final terms of the Re-profiling and Additional A Loans, including full form binding documentation, must be acceptable to TRQ and Rio Tinto in their respective discretion and will be subject to the approval of each of OT LLC, TRQ and Rio Tinto.

10.	Conditions. The Re-profiling and the Additional A Loans shall be subject to the satisfaction of the conditions set forth in Schedule C in favour of the parties (and which must be satisfied or waived by both parties in their respective discretion) on the Effective Date.

11.	TRQ DSU. If necessary for the Re-profiling, any Additional A Loans and the Co-Lending, TRQ shall agree to amend the TRQ DSU to cover such Re-profiling, Additional A Loans and Co-Lending on terms that are acceptable to TRQ in its discretion.

12.

Rio Tinto CSU. If necessary for the Re-profiling and any Additional A Loans, RTIHL shall cause Rio Tinto to agree to amend the Rio Tinto CSU to cover such Re-profiling and Additional A Loans on terms that are acceptable to Rio Tinto in its discretion. Rio Tinto shall be entitled to a Completion Support Agreement Fee in respect of such Re-profiling and Additional A Loans on the terms set out in Section 23 of the MOA mutatis mutandis.

Rio Tinto Co-Lending

13.

Commitment. Subject to Sections 14 to 18, RTIHL, on behalf of a member of the Rio Tinto Group to be designated by RTIHL (the “Rio Tinto Lender”), hereby provides a commitment to provide the lesser of (i) US$750 million, and (ii) the aggregate of the sums referred to in clauses 13a. and 13b., in the aggregate principal amount of senior loans to OT LLC (the “Co-Lending”) to cover in whole or in part:

the aggregate principal amount of any Senior Loan repayments required to be made from and including June 15, 2022 until and including June 15, 2024 after giving effect to the Re-profiling, if any; and

the shortfall, if any, between US$500 million and the aggregate principal amount of Additional A Loans secured by OT LLC,

all to be jointly determined by TRQ and RTIHL based on all relevant and up-to-date information to be provided to the parties by the Rio Tinto Manager.

14.

Key Terms. The Co-Lending shall take the form of pari passu Senior Loans under Clause 7.1(a) of the CTA and will share pro rata in the security package for the OT Project Financing on the same terms as the other Senior Loans. The Co-Lending shall constitute a separate Supplemental Senior Facility and shall have pricing (including all upfront and other fees) and maturity and other terms and conditions through the use of tranches that mirror the exact pricing (including all upfront and other fees), amortisation schedule, final maturity date and other terms and conditions of each tranche of the third party Senior Loans (excluding commercial bank tranches) that has been the subject of a full or partial Re-profiling or, if no Re-profiling has occurred, in accordance with Clause 7.2 (b) of the CTA. The Co-Lending shall be disbursed from time to time as OT LLC requires funding of OT Project costs upon satisfaction or waiver of the initial and subsequent conditions precedent with respect thereto as set forth in Schedules 2 and 3 of the CTA. To the extent the Re-profiling and/or the Additional A Loans is or are to occur in accordance with this Agreement, then the Effective Date of each element of Applicable Funding shall occur on the same date.

15.

Consent. TRQ consents, and RTIHL shall cause Rio Tinto to consent, to the Co-Lending in accordance with Clause 4.2(a) of the CTA, including the execution and delivery to the Intercreditor Agent of TRQ’s express consent to the Co-Lending becoming Guaranteed Senior Debt Obligations and Rio Tinto’s express consent to the Co-Lending becoming Covered Obligations.

16.

Approvals and Conditions. The execution and delivery by the Rio Tinto Lender of the Supplemental Senior Facility with respect to the Co-Lending shall be subject to (i) the satisfaction of the conditions set forth in Schedule C in favour of the Rio Tinto Lender on the Effective Date, (ii) the TRQ DSU being amended to cover the Co-Lending on terms that are acceptable to Rio Tinto, acting reasonably and (iii) the terms of the OT Project Financing Agreements with respect to a Sponsor Senior Loan not being amended in any material respect from the terms of the OT Project Financing Agreements existing as at the date of this Agreement (and each such condition in (i), (ii) and (iii) must be satisfied, or waived by the Rio Tinto Lender in its discretion, acting reasonably). For purposes of this Section 16, “material” includes any amendment to the OT Project Financing Agreements where the Rio Tinto Lender is treated different than the other Senior Lenders and such amendment is adverse to the Rio Tinto Lender or any of other member of the Rio Tinto Group.

17.

Timing. Without qualifying the commitment of the Rio Tinto Lender to provide the Co-Lending pursuant to Section 13 (subject to the conditions in Section 16 in favour of the Rio Tinto Lender on the Effective Date), each of the parties shall use its reasonable commercial efforts to cause the conditions in Section 16 within its control to be satisfied by no later than the Outside Date, provided that the parties shall first obtain the approval of the OT LLC board to commence negotiations for the Re-profiling, the Additional A Loans and Co-Lending. Subject to the conditions to the Co-Lending set forth in Section 16 having been satisfied (or otherwise waived by the Rio Tinto Lender in its discretion, acting reasonably), RTIHL shall cause the Rio Tinto Lender to execute all relevant Co-Lending transaction agreements and documents and make the Co-Lending available to OT LLC (i) if the Re-profiling and/or the Additional A Loans have been secured in accordance with the terms of this Agreement, on the Effective Date, (ii) if RTIHL withdraws from the process for the Re-profiling and Additional A Loans in accordance with Section 8, by no later than the earlier of the Outside Date and 15 days following the conditions to the Co-Lending set forth in Section 16 having been satisfied (or otherwise waived by the Rio Tinto Lender in its discretion, acting reasonably) and (iii) if TRQ withdraws from the process for the Re-profiling and Additional A Loans in accordance with Section 8, by no later than the Outside Date. If the conditions to the Co-Lending set forth in Section 16 are not satisfied (or otherwise waived by the Rio Tinto Lender in its discretion, acting reasonably) by the Outside Date, then RTIHL shall have no further obligations in respect of Sections 13 to 18.

18.

Rio Tinto CSU. RTIHL shall cause Rio Tinto to agree to amend the Rio Tinto CSU to cover the Co-Lending on the same terms as the existing Rio Tinto CSU or on such other terms that are acceptable to Rio Tinto in its discretion (acting reasonably), and Rio Tinto shall be entitled to a Completion Support Agreement Fee in respect of the Co-Lending on the terms set out in Section 23 of the MOA mutatis mutandis, commencing upon the first drawdown of the Co-Lending.

TRQ Equity Offering

19.

Key Terms and Objectives. Subject to Sections 20 to 23 and the Co-Lending having been made available, within six months following the Effective Date, TRQ covenants and agrees to conduct and complete an equity offering of its common shares (an “Equity Offering”) in the form of, at TRQ’s discretion, either (i) a rights offering of common shares (the “Rights Offering”) or (ii) a public offering or private placement of common shares (a “Placement”), in either case sufficient to generate an amount of gross proceeds (“Total Proceeds”) which will be not less than the lesser of (i) US$500 million and (ii) the Future Funding Shortfall. TRQ may in its discretion increase the Total Proceeds under the Equity Offering. TRQ shall provide RTIHL with notice of any such increase at least 20 days (or 30 days if any such increase is US$500 million or more) in the advance of the filing of any preliminary prospectus or offering memorandum or any other offering document or term sheet for the Equity Offering or such shorter period as RTIHL may indicate to TRQ is necessary to obtain any internal approvals. TRQ’s covenant and agreement to conduct and complete an Equity Offering hereunder shall be conditional upon, at such time, RTIHL being in compliance in all material respects with its obligations under this Agreement and each member of the Rio Tinto Group being in compliance in all material respects with its agreements, covenants and obligations under all other agreements with TRQ (or OT) (or the waiver of such condition by TRQ in its discretion, acting reasonably). Without limiting RTIHL’s rights under this Agreement, if, for any reason, TRQ does not complete the Equity Offering within six months following the Effective Date, any remaining availability under the Co-Lending may be terminated by the Rio Tinto Lender in its discretion. For greater certainty, any limitations or restrictions set forth in this Section 19 shall not apply, following the completion of the Equity Offering to be conducted by TRQ as required by this Agreement, to any placement or issuance of equity by TRQ made in accordance with TRQ’s rights under the existing agreements between TRQ and a member of the Rio Tinto Group.

20.

Rights Offering. Any Rights Offering will be conducted in a form and structure substantially similar to the rights offerings described in TRQ’s final short form prospectus and registration statements dated November 25, 2013 as modified by terms of this Agreement. TRQ agrees that the Rights Offering will not be subject to a minimum subscription condition or any other condition other than the mechanical conditions applicable to holders of rights respecting the exercise of their rights that are customary in rights offerings conducted by issuers having common shares listed on the TSX. All or part of the rights issued to any member of the Rio Tinto Group may be assigned by such members to one or more members of the Rio Tinto Group. The subscription price for each TRQ common share to be issued under the Rights Offering will be determined by TRQ prior to filing a final prospectus, subject to the price being a minimum 15% discount to the market price of TRQ’s common shares at the time of pricing of the Rights Offering (or such larger discount to the extent so required by the TSX).

21.

Placement. Each member of the Rio Tinto Group shall be entitled to maintain its pro rata ownership of TRQ as part of any Placement as provided for in the existing contractual agreements between the parties (more specifically, the PPA) (“Pro Rata Entitlement”). No Placement (or Rio Tinto’s Pro Rata Entitlement) shall require approval of the shareholders of TRQ unless the completion of the Placement and Rio Tinto’s Pro Rata Entitlement are conditional on the completion of the other with the objective of ensuring that a Placement may not be completed unless Rio Tinto is capable of availing itself of its Pro Rata Entitlement. All or part of the Pro Rata Entitlement may be assigned by the applicable member of the Rio Tinto Group to one or more other members of the Rio Tinto Group. For the avoidance of doubt, failure to obtain any required approval of the shareholders of TRQ does not in any way limit or defer TRQ’s obligation to conduct and complete an Equity Offering within six months following the Effective Date in accordance with the terms of this Agreement.

22.

Offering Documents. TRQ agrees to provide RTIHL and its advisors a reasonable opportunity to review and comment on any prospectus, registration statement, offering memorandum or other offering document or term sheet for any Equity Offering and other material communications with the TSX, NYSE and other regulatory authorities regarding any Equity Offering.

23.

Underwriting Commitment. If RTIHL elects to do so by notice to TRQ at least 10 days in advance of the filing of any preliminary prospectus for the Rights Offering, RTIHL may provide a standby underwriting commitment in respect of the Total Proceeds of the Rights Offering (the “Underwriting Commitment”). In consideration for the Underwriting Commitment, TRQ agrees to pay to RTIHL on closing of the Rights Offering a fee equal to 3% of the Total Proceeds. Other than the Underwriting Commitment, there shall be no additional standby underwriting commitment provided by any other person in respect of the Rights Offering. All or part of the Underwriting Commitment may be assigned by RTIHL to one or more members of the Rio Tinto Group. For greater certainty, in the event RTIHL is not providing an Underwriting Commitment with respect to the Rights Offering, then TRQ shall have the right to make all determinations regarding the identity of any standby commitment provider and the terms and conditions of such other standby underwriting commitment.

Other Funding Sources

24.

Proposals. After the Future Date, any proposal by TRQ or any of its subsidiaries or any of their respective representatives for any additional Senior Loans, bonds, streams prepays or other similar instruments at TRQ or any of its subsidiaries (including OT LLC) or accommodation for same in the OT Project Financing Agreements shall first be presented to Rio Tinto to obtain its consent (where such consent is required pursuant to existing contractual rights) and alignment of the parties before any such proposal is discussed or shared with EOT or GOM or at any OT LLC board or shareholder meeting. For the avoidance of doubt, without limiting the rights of the parties under the PPA and all other agreements between TRQ and a member of the Rio Tinto Group, TRQ shall not directly or indirectly, prior to completion of the Equity Offering, engage with EOT, GOM or the OT LLC board without having first obtained Rio Tinto’s consent, or the approval of the Technical Committee, in relation to any funding considerations or proposals.

25.

Funding Review. During the three month period following the Future Date, TRQ and Rio Tinto will meet to review the funding options for the Future Funding Shortfall. As part of this review, the parties will in good faith (i) discuss potential sources of funding and a potential funding plan to satisfy the Future Funding Shortfall (after taking into account the net proceeds received by TRQ under the Equity Offering) and (ii) discuss a potential implementation process for those potential sources of funding to which Rio Tinto may be prepared to consent at the time. If the parties agree on such a funding plan and implementation process, then the parties will endeavour to follow such plan and process and consider the terms of any agreed potential sources of funding. However, TRQ acknowledges that Rio Tinto has certain consent rights under its agreements with TRQ, including the TRQ FSA, and that certain funding proposals that TRQ may present to Rio Tinto may be subject to such consent rights and in no event shall this Section 25 constitute a waiver of any such rights under the TRQ FSA or otherwise.

26.

Rio Tinto Guidance. Other than the Re-profiling, Additional A Loans and the Co-Lending, Rio Tinto has advised TRQ that it has considered, and does not currently support or expect to consent to (where its consent is required), any additional debt (including additional Senior Loans and bonds) or other sources of funding (including streams and prepays) at TRQ or any of its subsidiaries (including OT LLC). TRQ acknowledges such guidance from Rio Tinto.

27.

TRQ Guidance. TRQ has advised Rio Tinto that, subject to the restrictions in this Agreement, (i) TRQ continues to prioritise OT LLC and/or TRQ raising funding by way of additional debt and / or hybrid funding and (ii) after the Future Date (subject to Section 32), TRQ may continue its evaluation of, and may present to Rio Tinto for its consideration and input, any such debt and hybrid funding options. Rio Tinto acknowledges such guidance from TRQ and confirms that, after the Future Date, it will consider all reasonable funding proposals presented to it by TRQ. TRQ acknowledges that Rio Tinto has certain consent rights under its agreements with TRQ, including the TRQ FSA, and that certain funding proposals that TRQ may present to Rio Tinto may be subject to such consent rights.

28.

Additional Rights Offerings. The parties acknowledge that any balance of the funding required for OT LLC to achieve completion of the underground mine may need to be met by way of one or more additional TRQ rights or other equity offerings if the Future Funding Shortfall is not fully addressed by the Re-profiling, Additional A Loans, Co-Lending, Equity Offering or other funding sources contemplated by Section 25. For the avoidance of doubt, other than Section 30, nothing in this Agreement shall in any way limit or waive Rio Tinto’s rights to require a TRQ rights offering under, and subject to, the TRQ FSA.

29.	Reservation of Rights. Except as expressly affected or modified by any provision of this Agreement, each of TRQ and RTIHL (on behalf of itself and Rio Tinto) reserves all of its rights in respect of its contractual rights in relation to funding and related consent matters.

30.

FSAs. Except as set out in Section 15, nothing in this Agreement shall constitute a consent, or in any way limit or waive Rio Tinto’s consent rights, under the TRQ FSA or the OT FSA or amount to a waiver or limitation of any existing contractual rights and obligations as between TRQ and any member of the Rio Tinto Group. Notwithstanding the foregoing, in determining whether TRQ or OT LLC has sufficient resources for purposes of Section 9 of the TRQ FSA or Section 9 of the OT FSA, such determination shall assume and take into account (A) prior to the earlier of (i) the Re-profiling and/or the Additional A Loans being secured and (ii) the Outside Date, TRQ having access to the entire proceeds from the Co-Lending (and, for the purposes of clause (A) of this Section 30, without consideration of whether or not the conditions to the availability of the Co-Lending set forth in Section 16 have been satisfied) and (B) after the Re-profiling and/or the Additional A Loans being secured, the actual amount of the Co-Lending then secured and available at any relevant point in time.

Power Funding

31.

If discussions with GOM result in a long-term domestic power supply arrangement that requires OT LLC to fund an additional power generation source and related infrastructure, the parties will consider a separate funding arrangement as may be agreed between TRQ and Rio Tinto in the form of additional Senior Loans or a stand-alone project financing or other financing instruments that may be appropriate.

Arbitration

32.

Subject to Section 29, the parties shall promptly seek from the Arbitrator, on a consent basis and without costs, a without prejudice dismissal of the Arbitration and an order vacating the Interim Measures Order. Except as permitted by this Agreement and subject to Section 24, TRQ shall not, directly or indirectly, seek or propose or engage in discussions regarding additional Senior Loans, bonds, streams, prepays or other similar instruments at TRQ or any of its subsidiaries (including OT LLC) or accommodation for same in the OT Project Financing Agreements. The restriction in the preceding sentence shall terminate upon the earlier of (i) the Effective Date and (ii) the Outside Date (the “Future Date”), unless the Future Funding Shortfall is US$500 million or less, in which case such restriction shall continue until the Support Termination Date and Section 25 shall not be applicable.

33.

Other than (i) any arbitration instituted or filed by any party pursuant to Section 52 which shall be permitted in relation to a breach by the other party of its obligations under this Agreement and (ii) any arbitration, litigation or other legal proceeding instituted or filed by either party to enforce its rights related to a breach of the other party’s obligations under any agreement between TRQ and RTIHL, each of TRQ and RTIHL agrees to not initiate or pursue, or make any public announcement threatening to initiate or pursue, any arbitration, litigation, injunction or other equitable relief or other legal proceeding regarding funding or related consent matters until after the completion of the Equity Offering.

GOM and EOT Support and Discussions

34.	The parties agree to use their respective reasonable commercial efforts to seek the support of the GOM and EOT to the Re-profiling, Additional A Loans and Co-Lending.

35.	TRQ acknowledges that the Rio Tinto Manager will lead discussions with GOM and EOT in consultation with TRQ.

Cash Management

36.

Except to the extent directly applied by OT LLC to the payment of OT Project costs within 30 days of receipt, all cash proceeds of the Additional A Loans and Co-Lending and the net proceeds provided by any member of the Rio Tinto Group under the Equity Offering (or Pro Rata Entitlement) shall be managed by a member of the Rio Tinto Group in accordance with an arrangement substantially similar to the arrangement set forth in the cash management services agreement dated December 15, 2015 between 9539549 Canada Inc., as service pro vider, TRQ and RTIHL.

Use of Proceeds

37.

Funding from the Additional A Loans, Co-Lending, Equity Offering and Pro Rata Entitlement shall be applied in the following order of priority: (i) to pay all required fees, costs and expenses of the Re-profiling, Additional A Loans, Co-Lending and Equity Offering; (ii) to fund OT Project costs relating to underground and power, if applicable, (including the servicing of Senior Loans and the payment of interest and fees in relation thereto); and (iii) to fund TRQ’s general and administrative costs.

Flow of Funds

38.

In connection with the completion of the Re-profiling, Additional A Loans, Co-Lending and Equity Offering, the parties shall enter into an agreed-upon flow of funds (i) in a form that is acceptable to the parties in their respective discretion and (ii) with indemnification obligations in the event of a failure to adhere to such flow of funds.

Representations and Warranties

39.	TRQ makes the representations and warranties set forth in Schedule D as at the date of this Agreement and the Effective Date and acknowledges that they may be relied upon by each of RTIHL and the Rio Tinto Lender.

40.	RTIHL makes the representations and warranties set forth in Schedule E as at the date of this Agreement and acknowledges that they may be relied upon by TRQ.

41.

The representations and warranties of the parties contained in this Agreement are only made as of the dates indicated in Sections 39 and 40 but survive for the purposes of allowing a party to sue for a breach of a representation and warranty that party is entitled to rely upon on the basis that the representation or warranty was not true as at the date such representation and warranty was made. No party shall be entitled to bring a claim on the basis of a breach of the representations and warranties that party is entitled to rely upon after the second anniversary of the date on which such representation and warranty was made.

Notifications

42.

Subject to any confidentiality obligations which may be imposed by any Governmental Authority, each party shall promptly notify the other of any material demand, request or inquiry (formal or informal) by any Governmental Authority, stock exchange, TRQ shareholder or other OT stakeholder that concerns any matter that may affect any of the transactions contemplated by this Agreement.
