(a) any tax, assessment or other governmental charge which would not have been imposed but for (i) the existence of any present or former connection between such Holder (or between a fiduciary, settlor, beneficiary, member or shareholder of, or possessor of a power over, such Holder, if such Holder is an estate, trust, partnership or corporation) and the taxing jurisdiction or any political subdivision or territory or possession thereof or area subject to its jurisdiction, including, without limitation, such Holder (or such fiduciary, settlor, beneficiary, member, shareholder or possessor) being or having been a citizen or resident thereof or being or having been present or engaged in trade or business therein or having or having had a permanent establishment therein or (ii) the presentation of a Security (where presentation is required) for payment on a date more than 30 days after the date on which such payment became due and payable or the date on which payment thereof is duly provided for, whichever occurs later;

Notwithstanding anything to the contrary contained herein, each of the Guarantors shall be entitled to withhold and deduct any amounts required to be deducted or withheld pursuant to an agreement described in Section 1471(b) of the Code, or otherwise imposed pursuant to Sections 1471 through 1474 of the Code (or any regulations thereunder or official interpretations thereof) or an intergovernmental agreement between the United States and another jurisdiction facilitating the implementation thereof (or any law implementing such an intergovernmental agreement) (any such withholding or deduction, a "FATCA Withholding"), and the Guarantors shall not be required to pay any additional amounts in respect of FATCA Withholding.]
Each of the Guarantors hereby agrees that its obligations hereunder shall be as if it were principal debtor and not merely surety, and shall be absolute and unconditional, irrespective of, and shall be unaffected by, any invalidity, irregularity or unenforceability of such Security or such Indenture, any failure to enforce the provisions of such Security or such Indenture, or any waiver, modification or indulgence granted to the Issuer with respect thereto, by the Holder of such Security or the Trustee or any other circumstance which may otherwise constitute a legal or equitable discharge of a surety or guarantor; provided however, that, notwithstanding the foregoing, no such waiver, modification or indulgence shall, without the consent of each of the Guarantors, increase the principal amount of such Security, or increase the interest rate thereon, or increase any premium payable upon redemption thereof, or alter the Stated Maturity thereof, or increase the principal amount of any Original Issue Discount Security that would be due and payable upon a declaration of acceleration of the maturity thereof pursuant to Section 502 of such Indenture. Each of the Guarantors hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of a merger or bankruptcy of the Issuer, any right to require a proceeding first against the Issuer, protest or notice with respect to such Security or the indebtedness evidenced thereby or with respect to any sinking fund or analogous payment require under such Security and all demands whatsoever, and covenants that this Guarantee will not be discharged except by payment in full of the principal of, premium, if any, and interest on such Security.

(9)Subsection (2) of Section 803 (Assumption by a Guarantor or Subsidiary of an Issuer’s Obligations) of the Base Indenture is amended to read in its entirety as follows :
(2) such Guarantor or Subsidiary, as the case may be, shall agree in such supplemental indenture, to the extent provided in the Securities and subject to the limitations and exceptions set forth below, that if any deduction or withholding for any present or future taxes, assessments or other governmental charges of the jurisdiction (or any political subdivision or taxing authority thereof or therein) in which such Guarantor or such Subsidiary is incorporated shall at any time be required by such jurisdiction (or any such political subdivision or taxing authority) in respect of any amounts to be paid by such Guarantor or Subsidiary, as the case may be, to a Holder, who, with respect to any such taxes, assessments or other governmental charges, is not resident in such jurisdiction, such Guarantor or Subsidiary, as the case may be, will pay to the Holder of a Security such additional amounts of interest as may be necessary in order that the net amounts paid to the Holder of such Security, after such deduction or withholding, shall not be less than the amounts specified in such Security to which such Holder is entitled; provided, however, that such Guarantor or Subsidiary, as the case may be, shall not be required to make any payment of additional amounts (i) if the Holder is a United States Person, for or on account of any such tax, assessment or other governmental charge imposed by the United States or any political subdivision or taxing authority thereof or therein, (ii) for or on account of: 
(a) any tax, assessment or other governmental charge which would not have been imposed but for (i) the existence of any present or former connection between such Holder (or between a fiduciary, settlor, beneficiary, member or shareholder of, or possessor of a power over, such Holder, if such Holder is an estate, trust, partnership or corporation) and the taxing jurisdiction or any political subdivision or territory or possession thereof or area subject to its jurisdiction including, without limitation, such Holder (or such fiduciary, settlor, beneficiary, member, shareholder or possessor) being or having been a citizen or resident thereof or being or having been present or engaged in trade or business therein or having or having had a permanent establishment therein or (ii) the presentation of a Security (where presentation is required) for payment on a date more than 30 days after the date on which such payment became due and payable or the date on which payment thereof is duly provided for, whichever occurs later;
(b) any estate, inheritance, gift, sale, transfer, personal property or similar tax, assessment or other governmental charge;
(c) any tax, assessment or other governmental charge which is payable otherwise than by withholding from payments of (or in respect of) principal of, premium, if any, or any interest on, the Securities;
(d) any tax, assessment or other governmental charge that is imposed or withheld by reason of the failure to comply by the Holder or the beneficial owner of Securities with a request of such Subsidiary or any Guarantor addressed to the Holder (i) to provide information concerning the nationality, residence or identity of the Holder or such beneficial owner or (ii) to make any declaration or other similar claim or satisfy any information or reporting requirement, which, in the case of (i) or (ii), is required or imposed by a statute, treaty, regulation or administrative practice of the taxing jurisdiction as a precondition to exemption from all or part of such tax, assessment or other governmental charge;
(e) in the case of a payment made by Rio Tinto plc under the Guarantees or a payment by Rio Tinto Finance (USA) plc, any tax, assessment or other governmental charge imposed as a result of the Security being presented for payment in the United Kingdom unless presentment could not have been made elsewhere;
			
	11









(f) any withholding or deduction required to be made with respect to a Security presented for payment by or on behalf of a Holder of such Security who would have been able to avoid such withholding or deduction by presenting the relevant Security to another Paying Agent; 
(g) any withholding or deduction required to be paid on the interest (as defined in Section 128A(1AB) of the Income Tax Assessment Act of 1936 of Australia (the "Australian Tax Act") and which, among other things, includes amounts in the nature of, or in substitution for, interest) payable on the debt security because the Holder of a Security is an "associate" of Rio Tinto Finance (USA) Limited (as that term is defined in section 128F(9) of the Australian Tax Act);
(h) any withholding or deduction for which a determination is made by the Australian Commissioner of Taxation that the withholding or deduction is payable because the Holder has participated in a scheme to avoid withholding tax provided that neither any Issuer nor any Guarantor participated in or was a party to such scheme;
(i)  in the case of any Securities issued by Rio Tinto Finance (USA) Inc., for or on account of any tax, duty, assessment or governmental charge that is imposed by reason of (A) the Holder’s or beneficial owner’s past or present status as the actual or constructive owner of 10% or more of the total combined voting power of all classes of stock of Rio Tinto Finance (USA) Inc. entitled to vote within the meaning of Section 871(h)(3) of the U.S. Internal Revenue Code of 1986, as amended (the “Code”), (B) the Holder’s or beneficial owner’s past or present status as a controlled foreign corporation that is related directly or indirectly to Rio Tinto Finance (USA) Inc. through stock ownership within the meaning of Section 864(d)(4) of the Code, (C) the Holder’s or beneficial owner’s being or having been a bank (or being or having been so treated) that is treated as receiving amounts paid on an extension of credit made pursuant to a loan agreement entered into in the ordinary course of its trade or business within the meaning of Section 881(c)(3)(A) of the Code, or (D) the Holder’s or beneficial owner’s failure to fulfil the statement requirements of Section 871(h) or 881(c) of the Code; or 
(j) any combination of items (a), (b), (c), (d), (e), (f), (g), (h) or (i);
nor shall additional amounts be paid with respect to any payment of the principal of, premium, if any, or any interest on any Security to any Holder who is a fiduciary or partnership or other than the sole beneficial owner of such payment to the extent such payment would be required by the laws of such jurisdiction (or any political subdivision or taxing authority thereof or therein) to be included in the income for tax purposes of a beneficiary or settlor with respect to such fiduciary or a member of such partnership or a beneficial owner who would not have been entitled to such additional amounts had it been the Holder of the Security;
Notwithstanding anything to the contrary contained herein, the relevant Issuer or, as the case may be, the Guarantors shall be entitled to withhold and deduct any amounts required to be deducted or withheld pursuant to an agreement described in Section 1471(b) of the Code, or otherwise imposed pursuant to Sections 1471 through 1474 of the Code (or any regulations thereunder or official interpretations thereof) or an intergovernmental agreement between the United States and another jurisdiction facilitating the implementation thereof (or any law implementing such an intergovernmental agreement) (any such withholding or deduction, a "FATCA Withholding"), and the relevant Issuer or Guarantors shall not be required to pay any additional amounts in respect of FATCA Withholding.


(10)Section 1004 (Additional Amounts) of the Base Indenture is amended to read in its entirety as follows:
If the Securities of a series provide for the payment of additional amounts, all payments of, or in respect of, principal of and any premium and interest on such Securities, and all 
			
	12









payments pursuant to any Guarantee on such Securities shall be made without any deduction or withholding for, or on account of, any present or future taxes, duties, assessments or other governmental charges of whatever nature imposed or levied by or on behalf of the jurisdiction (or any political subdivision or taxing authority thereof or therein) in which the Issuer of such Securities or (as the case may be) any Guarantor is incorporated unless such taxes, duties, assessments or other governmental charges are required by such jurisdiction (or any such subdivision or taxing authority thereof or therein) to be withheld or deducted. In that event, such Issuer or such Guarantor, as applicable, will pay to the Holder of a Security such additional amounts as may be necessary in order that the net amounts paid to the Holder of such Security who, with respect to any such tax, assessment, or other governmental charge, is not resident in such jurisdiction, after such deduction or withholding, shall be not less than the amounts specified in such Security to which such Holder is entitled; provided however, that such Issuer or such Guarantor shall not be required to make any payment of additional amounts (i) if the Holder is a United States Person for or on account of any such tax, assessment or other governmental charge imposed by the United States or any political subdivisions or taxing authority thereof or therein, (ii) for or on account of: 
(a) any tax, assessment or other governmental charge which would not have been imposed but for (i) the existence of any present or former connection between such Holder (or between a fiduciary, settlor, beneficiary, member or shareholder of, or possessor of a power over, such Holder, if such Holder is an estate, trust, partnership or corporation) and the taxing jurisdiction or any political subdivision or territory or possession thereof or area subject to its jurisdiction, including, without limitation, such Holder (or such fiduciary, settlor, beneficiary, member, shareholder or possessor) being or having been a citizen or resident thereof or being or having been present or engaged in trade or business therein or having or having had a permanent establishment therein or (ii) the presentation of a Security (where presentation is required) for payment on a date more than 30 days after the date on which such payment became due and payable or the date on which payment thereof is duly provided for, whichever occurs later;
(b) any estate, inheritance, gift, sale, transfer, personal property or similar tax, assessment or other governmental charge;
(c) any tax, assessment, or other governmental charge which is payable otherwise than by withholding from payments of (or in respect of) principal of, premium, if any, or interest on, the Securities;
(d) any tax, assessment or other governmental charge that is imposed or withheld by reason of the failure to comply by the Holder or the beneficial owner of a Security with a request of the Issuer of such Security or the applicable Guarantor addressed to the Holder (i) to provide information concerning the nationality, residence or identity of the Holder or such beneficial owner or (ii) to make any declaration or other similar claim or satisfy any information or reporting requirement, which, in the case of (i) or (ii), is required or imposed by a statute, treaty, regulation or administrative practice of the taxing jurisdiction as a precondition to exemption from all or part of such tax, assessment or other governmental charge;
(e) in the case of a payment made by Rio Tinto plc under the Guarantees or a payment by Rio Tinto Finance (USA) plc, any tax, assessment or other governmental charge imposed as a result of the Security being presented for payment in the United Kingdom unless presentment could not have been made elsewhere;
(f) any withholding or deduction required to be made with respect to a Security presented for payment by or on behalf of a Holder of such Security who would have been able to avoid such withholding or deduction by presenting the relevant Security to another Paying Agent; 
(g) any withholding or deduction required to be paid on the interest (as defined in Section 128A(1AB) of the Income Tax Assessment Act of 1936 of Australia (the "Australian 
			
	13









Tax Act") and which, among other things, includes amounts in the nature of, or in substitution for, interest) payable on the debt security because the Holder of a Security is an "associate" of Rio Tinto Finance (USA) Limited (as that term is defined in section 128F(9) of the Australian Tax Act);
(h) any withholding or deduction for which a determination is made by the Australian Commissioner of Taxation that the withholding or deduction is payable because the Holder has participated in a scheme to avoid withholding tax provided that neither the Issuer of the relevant series of Securities nor any Guarantor participated in or was a party to such scheme;
(i)  in the case of any Securities issued by Rio Tinto Finance (USA) Inc., for or on account of any tax, duty, assessment or governmental charge that is imposed by reason of (A) the Holder’s or beneficial owner’s past or present status as the actual or constructive owner of 10% or more of the total combined voting power of all classes of stock of Rio Tinto Finance (USA) Inc. entitled to vote within the meaning of Section 871(h)(3) of the U.S. Internal Revenue Code of 1986, as amended (the “Code”), (B) the Holder’s or beneficial owner’s past or present status as a controlled foreign corporation that is related directly or indirectly to Rio Tinto Finance (USA) Inc. through stock ownership within the meaning of Section 864(d)(4) of the Code, (C) the Holder’s or beneficial owner’s being or having been a bank (or being or having been so treated) that is treated as receiving amounts paid on an extension of credit made pursuant to a loan agreement entered into in the ordinary course of its trade or business within the meaning of Section 881(c)(3)(A) of the Code, or (D) the Holder’s or beneficial owner’s failure to fulfil the statement requirements of Section 871(h) or 881(c) of the Code; or 
(j) any combination of items (a), (b), (c), (d), (e), (f), (g), (h) or (i);
nor shall additional amounts be paid with respect to any payment of the principal of, premium, if any or any interest on any Security to any Holder who is a fiduciary or partnership or other than the sole beneficial owner of such payment to the extent such payment would be required by the laws of the jurisdiction (or any political subdivision or taxing authority thereof or therein) to be included in the income for tax purposes of a beneficiary or settlor with respect to such fiduciary or a member of such partnership or a beneficial owner who would not have been entitled to such additional amounts had it been the Holder of the Security.
Notwithstanding anything to the contrary contained herein, the relevant Issuer or, as the case may be, the Guarantors shall be entitled to withhold and deduct any amounts required to be deducted or withheld pursuant to an agreement described in Section 1471(b) of the Code, or otherwise imposed pursuant to Sections 1471 through 1474 of the Code (or any regulations thereunder or official interpretations thereof) or an intergovernmental agreement between the United States and another jurisdiction facilitating the implementation thereof (or any law implementing such an intergovernmental agreement) (any such withholding or deduction, a "FATCA Withholding"), and the relevant Issuer or Guarantors shall not be required to pay any additional amounts in respect of FATCA Withholding.
Whenever in this Indenture there is mentioned, in any context, the payment of the principal of or any premium or interest on, or in respect of, any Security of any series or the net proceeds received on the sale or exchange of any Security of any series, such mention shall be deemed to include mention of the payment of additional amounts provided for in this Section to the extent that, in such context, additional amounts are, were or would be payable in respect thereof pursuant to the provisions of this Section and express mention of the payment of additional amounts (if applicable) in any provisions hereof shall not be construed as excluding additional amounts in those provisions hereof where such express mention is not made.
If the Securities of a series provide for the payment of additional amounts, at least 10 days prior to the first Interest Payment Date with respect to that series of Securities (or if 
			
	14









the Securities of that series will not bear interest prior to Maturity, the first day on which a payment of principal and any premium is made), and at least 10 days prior to each date of payment of principal and any premium or interest if there has been any change with respect to the matters set forth in the below-mentioned Officer's Certificate, the Issuer of such Securities will furnish the Trustee and such Issuer’s principal Paying Agent or Paying Agents, if other than the Trustee, with an Officer's Certificate instructing the Trustee and such Paying Agent or Paying Agents whether such payment of principal of and any premium or interest on the Securities of that series shall be made to Holders of Securities of that series without withholding for or on account of any tax, assessment or other governmental charge described in the Securities of that series. If any such withholding shall be required, then such Officer's Certificate shall specify by country the amount, if any, required to be withheld on such payments to such Holders of Securities and the Issuer of such Securities or the Guarantor, as the case may be, will pay to the Trustee or such Paying Agent or Paying Agents the additional amounts required by this Section. Each Issuer and the Guarantors covenant to indemnify the Trustee and any Paying Agent for, and to hold them harmless against, any loss, liability or expense reasonably incurred without negligence or bad faith on their part arising out of or in connection with actions taken or omitted by any of them in reliance on any Officer's Certificate furnished pursuant to this Section.
