#### Interest rates
In addition to debt securities that bear interest at fixed rates, we may, from time to time, issue floating rate debt securities that bear interest at rates based on other interest rates as may be described in the applicable prospectus supplement.

#### Guarantees
Both Rio Tinto plc and Rio Tinto Limited will fully and unconditionally guarantee the payment of the principal of, premium, if any, and interest on the debt securities, including any additional amounts which may be payable in respect of the debt securities, as described under “— Special Situations — Payment of Additional Amounts ”. Rio Tinto plc and Rio Tinto Limited guarantee the payment of such amounts when such amounts become due and payable, whether at the stated maturity of the debt securities, by declaration or acceleration, call for redemption or otherwise. Each of Rio Tinto plc and Rio Tinto Limited is individually obligated to pay such amounts.

These intermediary banks, brokers and other financial institutions pass along principal, interest and other payments on the debt securities, either because they agree to do so in their customer agreements or because they are legally required to do so. Holders of debt securities who hold in street name should check with their institutions to find out:

Our obligations, as well as the obligations of the trustee and those of any third parties employed by us or the trustee, run only to persons who are registered as holders of debt securities. As noted above, we
