ARTICLE 2

EARLY ADVANCE FACILITY

2.1 The Early Advance Facility

Upon the terms and subject to the conditions of this Agreement, the Lender will make the Early Advance Facility available to the Borrower during the Availability Period in the aggregate amount up to the Early Advance Facility Commitment Amount. The Early Advance Facility Commitment Amount shall be automatically reduced by the amount of each Loan advanced from time to time under the Early Advance Facility. The Early Advance Facility will be non-revolving and amounts repaid or prepaid thereunder may not be re-borrowed or otherwise become the subject of any further advance thereunder.

2.2 Purpose

The proceeds of the Loans advanced under the Early Advance Facility shall be used by the Borrower and its Subsidiaries solely to fund Prepayment Advances under the Prepayment Agreement, which shall be used by OT LLC in accordance with clause 2.4 of the Prepayment Agreement, and to fund (i) amounts on account of interest payable on the outstanding principal amount under the Early Advance Facility in respect of any Interest Period in accordance with Section 6.3 (grossed up for any Tax deduction in accordance with Article 9), (ii) all fees, expenses and transaction costs (including the Commitment Fees) arising under this Agreement (grossed up for any Tax deduction in accordance with Article 9), and (iii) the Borrower an amount required to bring Available Funds to zero (and re-establish the Permitted Working Capital Reserve at US$200,000,000).

2.3 Payment Instructions

(a) The amount of each Loan made under the Early Advance Facility that is to be provided to the Borrower will be paid by the Lender to the OT Cash Call Account in accordance with the wire transfer instructions set out in Part C of Schedule H. Thereafter, the Borrower will cause the amount of each Loan deposited to the OT Cash Call Account (excluding the amount of the Loan provided to the Borrower pursuant to Subsections 2.3(b), 2.3(c) and 2.3(d)) to be paid forthwith and without delay to OT LLC as a Prepayment Advance pursuant to the Prepayment Agreement. If the Lender determines that Schedule H should no longer apply to Loans made hereunder, each Loan shall be made in such other manner as the Lender and the Borrower may otherwise agree provided that, in such case, the

- 19 -

Lender must be satisfied, acting reasonably, with the form (whether debt, convertible debt, equity or otherwise) of any proposed investment to be made by the Borrower and/or any of its Subsidiaries in any Subsidiary of the Parent (including, for certainty, OT LLC) using funds provided by any member of the Rio Tinto Group under this Agreement, and with the particular proposed Subsidiaries of the Parent (including, for certainty, OT LLC) in which such funds are to be directly or indirectly invested.

(b) To the extent that a Loan requested by the Borrower under this Agreement (i) includes funds that are to be utilized for purposes of paying applicable Tax deductions on payments of interest, or fees, expenses or transaction costs (including the Commitment Fees) arising under this Agreement, in accordance with Section 9.1, or (ii) includes funds that are to be utilised for the purposes of paying any accumulated interest on the funds identified in the foregoing clause (i), then, in each case, the funds will be provided directly to the Borrower and will not be made available to OT LLC.

(c) To the extent that a Loan requested by the Borrower under this Agreement includes funds which are to be utilized (i) for any interest payable by the Borrower hereunder, or (ii) for its payment of fees, expenses or transaction costs (including the Commitment Fees) arising under this Agreement (or any portion of any of them), such funds will be provided directly to the Borrower and will not be made available to OT LLC.

(d) To the extent that a Loan requested by the Borrower under this Agreement includes funds which are being provided to the Borrower for the purpose of bringing Available Funds to zero (and re-establishing the Permitted Working Capital Reserve at US$200,000,000), such funds will be provided directly to and will be held by the Borrower and will not be made available to OT LLC. The Borrower shall not further advance such funds to the Parent without first consulting with the Lender, as to the form (whether debt, convertible debt, equity or otherwise) by which such funds will be provided by the Borrower to the Parent. In their determination of the appropriate form, the Borrower and the Parent, in consultation with the Lender, will make all reasonable efforts to limit potential adverse consequences to the Lender. Notwithstanding the foregoing, the Borrower shall not further advance such funds to, or utilize such funds for the benefit of, any Subsidiary of the Parent, directly or indirectly, in one or more series of transactions, without the prior approval of the Lender.

2.4 Monitoring

The Lender is not bound to monitor or verify the application of any amount borrowed pursuant to this Agreement.

2.5 Availability Period and Maturity Date

(a) Drawdowns of Loans under the Early Advance Facility will be available from the Closing Date until the expiration of the Availability Period (subject to, in the case of an initial advance of a Loan hereunder, the prior satisfaction of the conditions precedent in Section 4.1 and for each advance of a Loan thereafter, subject to the prior satisfaction of the conditions precedent in Section 4.2). No drawdowns of Loans under the Early Advance Facility may be made by the Borrower following the end of the Availability Period, notwithstanding that the Early Advance Facility may not have been fully drawn by such time.

(b) The Early Advance Facility will mature and be cancelled on the Maturity Date, and all principal, interest and other amounts owing or outstanding under this Agreement will be finally due and payable, on such Maturity Date (subject to any provision of this Agreement requiring the Borrower to repay the Obligations in full prior to such date).

ARTICLE 6

INTEREST

6.1 Calculation of Interest

(a) Prior to the occurrence of an Event of Default, the Borrower will pay in respect of each Interest Period, in accordance with Section 6.3, interest on the principal amount of Loans under the Early Advance Facility from time to time outstanding and on overdue interest thereon, at a rate per annum equal to the sum of (i) the one month LIBOR Rate in effect hereunder for each Loan plus (ii) the Margin. Interest on the principal amount of each Loan under the Early Advance Facility outstanding from time to time and on overdue interest thereon shall accrue from day to day including the Funding Date thereof or the date on which such overdue interest is due, as the case may be, until the final repayment of all amounts due hereunder (both before and after maturity and after as well as before judgement) and shall be calculated on the basis of the actual number of days elapsed divided by 360.

(b) Each determination by the Lender of the LIBOR Rate applicable from time to time will, in the absence of manifest error, be binding upon the Borrower. Changes in the LIBOR Rate, if any, on the date of determination by the Lender in respect of any Interest Period in accordance with the definition of LIBOR Rate will cause an immediate adjustment of the interest rate for such Interest Period applicable to the corresponding Loans without necessity of any notice to the Borrower. The Lender shall use reasonable efforts to notify the Borrower of the applicable LIBOR Rate following each determination thereof by the Lender from time to time in accordance with the provisions of this Agreement and the Borrower agrees that there shall be no recourse against the Lender for any liability to the Lender arising in connection with a failure by the Lender to deliver any such notice to the Borrower and that any failure by the Lender to deliver any such notice to the Borrower does not constitute a waiver, release or discharge of any of the indebtedness, or of any of the terms, covenants, conditions or provisions of this Agreement and the other Facility Documents and the same shall continue until terminated in accordance with the terms hereof.

6.2 Default Interest

If an Event of Default has occurred and is continuing, until the same has been remedied in full, the Borrower shall pay interest (after as well as before judgment) on the aggregate amount of Loans made under the Early Advance Facility from time to time outstanding and on any other payment obligation under this Agreement outstanding at a daily rate equal to the sum of:

(a) the one month LIBOR Rate in effect for each Loan plus the Margin; plus

(b) two hundred (200) basis points.

- 27 -

6.3 Payment Dates and Calculation Information

While any principal amount of any Loan is outstanding under the Early Advance Facility during an Interest Period, interest accrued thereon during such Interest Period will be paid by the Borrower to the Lender in arrears on each Payment Date, in accordance with the payment instructions provided from time to time by the Lender to the Borrower. All payments of interest will be grossed up for any Tax deductions in accordance with Section 9.1. Absent manifest error in the calculation of such interest amount, the interest calculation of the Lender pursuant to this Article 6 for any particular Interest Period will be the amount of interest to be paid by the Borrower on the applicable Payment Date. Until the end of the Availability Period, any amounts on account of interest payable on all outstanding Loans may be funded in whole or in part from a further Loan made hereunder if requested in (i) a Funding Request or (ii) a written request provided by the Parent to the Lender at least 5 Business Days prior to the applicable Payment Date, which request shall direct and authorize the Lender to deem to advance such Loan to the Borrower and apply such Loan against the accrued interest payable by the Borrower to the Lender on such Payment Date.

6.4 Inability to Determine Rates

If at any time the Lender determines that for any reason adequate and reasonable means do not exist for determining the LIBOR Rate for the Interest Period with respect to a proposed Loan, or that the LIBOR Rate for the Interest Period with respect to a proposed Loan does not adequately and fairly reflect the cost to the Lender of funding such Loan, the Lender will promptly so notify the Borrower. Immediately after such determination by the Lender, the Lender and the Borrower shall negotiate in good faith to mutually agree upon a successor rate to LIBOR Rate for purposes of this Agreement, and the Lender and the Borrower shall amend this Agreement to replace LIBOR Rate with an alternative interest rate benchmark (including any mathematical or other adjustments to the benchmark (if any) incorporated therein), giving due consideration to any evolving or then existing convention for similar US Dollar denominated credit facilities for such alternative benchmarks.

ARTICLE 7

The Borrower shall pay to the Lender a commitment fee quarterly (on the Business Day which first follows 31 March, 30 June, 30 September and 30 December of each year) in arrears calculated at the Commitment Fee Rate on an annual basis on the daily average of the undrawn principal amount under the Early Advance Facility (the “Commitment Fee”).

The Commitment Fee will accrue from the date of this Agreement until the date on which the Availability Period terminates in accordance with the terms of this Agreement and any outstanding Commitment Fee will be payable in full on the Maturity Date. In the event that the Early Advance Facility is cancelled in accordance with the terms hereof or is repaid, prepaid and cancelled in its entirety pursuant to the terms hereof prior to the end of the Availability Period, any unpaid Commitment Fee in respect of the portion of the Calculation Period ending on the date of cancellation, repayment or prepayment will be accelerated and will be payable on the date of such cancellation, repayment or prepayment and termination. For greater certainty, if any amount remains undrawn under the Early Advance Facility on the Maturity Date, any unpaid Commitment Fee in respect of the portion of the Calculation Period ending on the Maturity Date will be accelerated and will be payable on the Maturity Date.

14.7 Inconsistency with Other Facility Documents

To the extent that any term, condition, representation, covenant or other provision contained in any Facility Document (other than this Agreement) is at any time inconsistent or conflicts with any term, condition, representation, covenant or other provision contained in this Agreement, then the provisions of this Agreement shall prevail and govern.

14.10 Remedies Cumulative

For greater certainty, it is expressly understood that the rights and remedies of the Lender hereunder or under any other Facility Document or instrument executed pursuant to this Agreement are cumulative and are in addition to and not in substitution for any rights or remedies provided by law or by equity; and any single or partial exercise by the Lender of any right or remedy for a default or breach of any term, covenant, condition or agreement contained in this Agreement or any other Facility Document will not be deemed to be a waiver of or to alter, affect or prejudice any other right or remedy or other rights or remedies to which the Lender may be lawfully entitled in connection with such default or breach.

14.11 Perform Obligations

If an Event of Default has occurred and is continuing and if any Obligor has failed to perform any covenant or agreement given by it in any Facility Document, the Lender may perform any such covenant or agreement in the manner deemed fit by the Lender without thereby waiving any rights to enforce such Facility Document. The reasonable expenses (including any legal costs) incurred by the Lender in respect of the foregoing will constitute a part of the Obligations and will be secured by the Collateral Documents.

14.13 Third Parties

It is not necessary for any Person dealing with the Lender, or any other agent of the Lender to inquire whether any Collateral Document has become enforceable, or whether the powers that the Lender is purporting to exercise may be exercised, or whether any Obligations remains outstanding upon the security thereof, or as to the necessity or expediency of the stipulations and conditions subject to which any sale is to be made, or otherwise as to the propriety or regularity of any sale or other disposition or any other dealing with the collateral charged by such Collateral Document or any part thereof.

No modification, rescission, waiver, release, or amendment of any provision of this Agreement shall be made, except by a written agreement signed by the Obligors and a duly authorized officer of the Lender.

14.17 Entire Agreement

This Agreement supersedes any previous agreement between the Parties relating to the subject matter of this Agreement.

14.18 Currency Conversion Indemnity

If:

(a) any amount payable under, or in connection with any matter relating to or arising out of, the Facility Documents, is received by the Lender in a currency (the “Payment Currency”) other than that agreed to be payable thereunder (the “Agreed Currency”), whether voluntarily or pursuant to an order, judgment or decision of any court, tribunal, arbitration panel or administrative agency or as a result of any bankruptcy, receivership, liquidation or other insolvency type proceedings or otherwise; and

(b) the amount so received by converting the Payment Currency so received into the Agreed Currency is less than the relevant amount of the Agreed Currency;

- 48 -

then:

(c) the amount so received shall constitute a discharge of the liability of the Obligors under or in connection with the Facility Documents only to the extent of the amount of Agreed Currency received following the conversion described in paragraph (b) above; and

(d) the Obligors shall forthwith indemnify and save the Lender harmless from and against such deficiency of Agreed Currency and any loss or damage arising as a result thereof.

Any conversion pursuant to this Section 14.18 shall be made at such prevailing rate of exchange on such date as is within three (3) Business Days following the date the Payment Currency is received by the Lender and in such market as is determined by the Lender as being the most appropriate for such a conversion. The Obligors shall, in addition, pay the reasonable costs of such conversion.

14.19 Day count convention

14.20 Counterparts

This Agreement may be executed in any number of counterparts, and by the Lender and the Obligors in separate counterparts, each of which shall be an original, but all of which shall together constitute one and the same agreement.

14.21 Electronic Execution

Delivery of an executed signature page to this Agreement by either Party by electronic transmission will be as effective as delivery of a manually executed copy of the Agreement by such Party. The words “execution”, “signed”, “signature”, and words of like import in this Agreement shall be deemed to include electronic signature or the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature or the use of a paper based recordkeeping system, as the case may be.

- 57 -

2.05 Exception for Contractual Rights

3.02 Registration of Securities

The Secured Party may have any Securities registered in its name or in the name of its nominee and will be entitled but not required to exercise any of the rights that any holder of such Securities may at any time have. However, until an Event of Default has occurred and continued and the Secured Party has exercised any of its rights and remedies pursuant to Section 4.01, the Debtor will be entitled to exercise, in a manner not prejudicial to the interests of the Secured Party or which would not violate or be inconsistent with this Agreement, all voting power from time to time exercisable in respect of the Securities. The Secured Party will not be responsible for any loss occasioned by its exercise of any of such rights or by failure to exercise the same within the time limited for the exercise thereof. The Debtor must from time to time forthwith upon the request of the Secured Party deliver to the Secured Party those Securities requested by the Secured Party duly endorsed for transfer to the Secured Party or its nominee.

3.03 Notification of Account Debtors

Before an Event of Default occurs, the Secured Party may give notice of this Agreement and the security granted hereby to any account debtor of the Debtor or to any other person liable to the Debtor and, after the occurrence of an Event of Default which is continuing and the exercise by the Secured Party of any of its rights and remedies pursuant to Section 4.01, may give notice to any such account debtors or other person to make all further payments to the Secured Party. Any payment or other proceeds of Collateral received by the Debtor from account debtors or from any other person liable to the Debtor after the occurrence and during the continuance of such Event of Default and exercise of such rights and remedies will be held by the Debtor in trust for the Secured Party and must be held separate and apart from other money of the Debtor and paid over to the Secured Party on request.

- 58 -

3.04 Application of Funds

All money collected or received by the Secured Party in respect of the Collateral may be applied on account of such parts of the Obligations as the Secured Party in its sole discretion determines, or may be held unappropriated in a collateral account, or in the discretion of the Secured Party may be released to the Debtor, all without prejudice to the Secured Party’s rights against the Debtor.

ARTICLE 4 - REMEDIES

If acceleration of the time for payment of any amount payable by the Obligor in respect of the Obligations is stayed upon the insolvency, bankruptcy, arrangement or reorganization of the Obligor or any moratorium affecting the payment of the Obligations, all such amounts that would otherwise be subject to acceleration will nonetheless be payable by the Guarantor hereunder forthwith on the demand by the Secured Party.

4.03 Interest

Without duplication of interest accruing on the Obligations, the Guarantor will pay interest to the Secured Party on the unpaid portion of all amounts payable by the Guarantor under this Guarantee, including all costs and expenses incurred by the Secured Party in collecting and enforcing the Obligations and in enforcing this Guarantee, at the rate or rates provided in the Early Advance Funding Agreement for the Obligations, such interest to accrue from and including the date of demand by the Secured Party on the Guarantor to but excluding the date of payment thereof by the Guarantor.

ARTICLE 5 - ASSIGNMENT, POSTPONEMENT AND SUBROGATION

5.01 Assignment and Postponement

All debts and liabilities, present and future, of the Obligor to the Guarantor are hereby assigned to the Secured Party and postponed to the Obligations, and all money received by the Guarantor in respect thereof will be held in trust for the Secured Party and forthwith upon receipt will be paid over to the Secured Party, the whole without in any way lessening or limiting the liability of the Guarantor hereunder and this assignment and postponement is independent of the guarantee, indemnity and primary obligor obligations contained in this Guarantee and will remain in full force and effect until, in the case of the assignment, the liability of the Guarantor under this Guarantee has been discharged or terminated and, in the case of the postponement, until all Obligations are performed and indefeasibly paid in full.

- 75 -

5.02 Subrogation

The Guarantor will not be entitled to subrogation until (a) the Guarantor performs or makes indefeasible payment to the Secured Party of all amounts owing by the Guarantor to the Secured Party under this Guarantee, (b) the Obligations are indefeasibly paid in full and (c) the Secured Party has no further liability to advance money to, or incur any liability on behalf of, the Obligor. Thereafter, the Secured Party will, at the Guarantor’s request and expense, execute and deliver to the Guarantor appropriate documents, without recourse and without representation and warranty, necessary to evidence the transfer by subrogation to the Guarantor of an interest in the Obligations and any security held therefor resulting from such performance or payment by the Guarantor.

ARTICLE 6 - GENERAL

6.01 Waiver of Notices

(1) The Guarantor hereby waives promptness, diligence, presentment, demand of payment, notice of acceptance and any other notice with respect to this Guarantee and the Obligations guaranteed hereunder, except for the demand pursuant to Section 4.01.

(2) The Guarantor hereby waives any requirement for the Secured Party to provide copies of registrations, verification statements, financing statements, financing change statements or similar documents undertaken by the Secured Party pursuant to the Personal Property Security Act (British Columbia) or equivalent legislation in other jurisdictions (including the Civil Code of Québec).

6.02 Binding Effect of the Guarantee

This Guarantee will be binding upon the successors of the Guarantor and will enure to the benefit of the Secured Party and its successors and assigns.

6.03 Foreign Currency Obligations

The Guarantor will make payment relative to each Obligation in the currency (the “original currency”) in which the Obligor is required to pay such Obligation. If the Guarantor makes payment relative to any Obligation to the Secured Party in a currency (the “other currency”) other than the original currency (whether voluntarily or pursuant to an order or judgment of a court or tribunal of any jurisdiction), such payment will constitute a discharge of the liability of the Guarantor hereunder in respect of such Obligation only to the extent of the amount of the original currency that the Secured Party is able to purchase with the amount of the other currency it receives on the date of receipt, as determined by the Secured Party in accordance with its normal practice. If the amount of the original currency that the Secured Party is able to purchase is less than the amount of such currency originally due in respect of the relevant Obligation, the Guarantor will indemnify and save the Secured Party harmless from and against any loss or damage arising as a result of such deficiency. This indemnity will constitute an obligation separate and independent from the other obligations contained in this Guarantee, will give rise to a separate and independent cause of action, will apply irrespective of any indulgence granted by the Secured Party and will continue in full force and effect notwithstanding any judgment or order in respect of any amount due hereunder or under any judgment or order. A certificate of the Secured Party as to any such loss or damage will constitute prima facie evidence thereof, in the absence of manifest error.

6.04 Entire Agreement

This Guarantee constitutes the entire agreement between the Guarantor and the Secured Party with respect to the subject matter hereof and cancels and supersedes any prior understandings and agreements between such parties with respect thereto. There are no representations, warranties, terms, conditions, undertakings or collateral agreements, express, implied or statutory, between the parties except as expressly set forth herein. The Secured Party will not be bound by any representations or promises made by the Obligor to the Guarantor and possession of this Guarantee by the Secured Party will be conclusive evidence against the Guarantor that this Guarantee was not delivered in escrow or pursuant to any agreement that it should not be effective until any condition precedent or subsequent has been complied with and this Guarantee will be operative and binding against the Guarantor notwithstanding the non execution thereof by any other proposed signatory.

6.05 Financial Condition of Obligor

The Guarantor is fully aware of the financial condition of the Obligor. So long as any of the Guarantor’s obligations hereunder remain undischarged the Guarantor will assume sole responsibility for keeping itself informed of the financial condition of the Obligor and of all circumstances bearing upon the nature, scope and extent of the risk that the Guarantor assumes or incurs hereunder and the Secured Party will not have a duty to advise the Guarantor of information known to the Secured Party regarding such circumstances or risks.

6.06 Acknowledgement of Documentation

The Guarantor acknowledges receipt of a true and complete copy of each of the Facility Documents and all of the terms and conditions thereof. So long as any of the Guarantor’s obligations hereunder remain undischarged the Guarantor will assume sole responsibility for keeping itself informed, and requesting and obtaining copies from the Obligor or otherwise, of all amendments, modifications, supplements, restatements and replacements of the Facility Documents and the Secured Party will not have a duty to advise or provide copies to the Guarantor of any such amendments, modifications, supplements, restatements and replacements.

6.07 Amendments and Waivers

No amendment to this Guarantee will be valid or binding unless set forth in writing and duly executed by the Guarantor and the Secured Party. No waiver of any breach of any provision of this Guarantee will be effective or binding unless made in writing and signed by the party purporting to give the same and, unless otherwise provided in the written waiver, will be limited to the specific breach waived.

6.08 Severability

If any provision of this Guarantee is determined by any court of competent jurisdiction to be illegal or unenforceable, that provision will be severed from this Guarantee and the remaining provisions will continue in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to either the Secured Party or the Guarantor.

6.09 Notices

Any demand, notice or other communication to be given in connection with this Guarantee shall be given in accordance with Section 14.5 of the Early Advance Funding Agreement.

6.10 Discharge

Unless all obligations of the Guarantor hereunder have been indefeasibly paid or performed, the Guarantor will not be discharged from any of its obligations hereunder except by a release or discharge signed in writing by the Secured Party.

6.11 Remedies Cumulative

The rights and remedies of the Secured Party hereunder are cumulative and are in addition to, and not in substitution for, any other rights and remedies available at law or in equity or otherwise. No single or partial exercise by the Secured Party of any right or remedy precludes or otherwise affects the exercise of any other right or remedy to which the Secured Party may be entitled.

6.12 Governing Law

This Guarantee is governed by and will be construed in accordance with the laws of the Province of British Columbia and the federal laws of Canada applicable therein.

6.13 Arbitration

The Guarantor and the Secured Party agree that any matter in dispute under this Agreement will be determined by arbitration in accordance with Part 16 of the PPA, mutatis mutandis, and, for the avoidance of doubt, the provisions of Part 16 of the PPA permitting a party to apply to a court of competent jurisdiction in the circumstances set out therein (including, without limitation, for the purpose of seeking temporary injunctive relief) shall apply to this Guarantee, mutatis mutandis, provided that the Guarantor and the Secured Party submit to the non-exclusive jurisdiction of the courts of the Province of British Columbia in such circumstances.
