TABLE OF CONTENTS

Since the Notes are unsecured, your right to receive payments may be adversely affected

The Notes that we are offering will be unsecured. If we default on the Notes or Rio Tinto defaults on the guarantees, or after bankruptcy, liquidation or reorganization, then, to the extent that we or Rio Tinto have granted security over our or Rio Tinto’s assets, the assets that secure our or Rio Tinto’s debts will be used to satisfy the obligations under that secured debt before we or Rio Tinto could make payment on the Notes or the guarantees. There may only be limited assets available to make payments on the Notes or the guarantees in the event of an acceleration of the Notes. If there is not enough collateral to satisfy the obligations of the secured debt, then the remaining amounts on the secured debt would share equally with all unsubordinated unsecured indebtedness.

We or Rio Tinto may incur substantially more debt in the future

We or Rio Tinto may incur substantial additional indebtedness in the future, including in connection with future acquisitions, some or all of which may be secured by our or Rio Tinto’s assets. The terms of the Notes will not limit the amount of indebtedness we or Rio Tinto may incur. Any such incurrence of additional indebtedness could exacerbate the risks that holders of the Notes now face.

#### The Notes lack a developed public market
There can be no assurance regarding the future development of a market for the Notes or the ability of holders of the Notes to sell their Notes or the price at which such holders may be able to sell their Notes. If such a market were to develop, the Notes could trade at prices that may be higher or lower than the initial offering price depending on many factors, including, among other things, prevailing interest rates, our or Rio Tinto’s operating results and the market for similar notes. The underwriters may make a market in the Notes as permitted by applicable laws and regulations. However, the underwriters are not obligated to do so, and any such market-making activities with respect to the Notes may be discontinued at any time without notice. Therefore, there can be no assurance as to the liquidity of any trading market for the Notes or that an active public market for the Notes will develop. See “Underwriting”.
