 the trustee and bringing a lawsuit or other formal legal action or taking other steps to enforce rights or protect interests relating to the debt securities, the following must occur:

•

The trustee must be given written notice that an event of default has occurred and remains uncured.

•

The holders of 25% in principal amount of all outstanding debt securities of the relevant series must make a written request that the trustee take action because of the default, and must offer reasonable indemnity to the trustee against the cost and other liabilities of taking that action.

•

The trustee must have not taken action for 60 days after receipt of the above notice and offer of indemnity and the trustee has not received an inconsistent direction from the holders of a majority in principal amount of all outstanding debt securities during that period. ( Section 507 of the Base Indenture )

However, such limitations do not apply to a suit instituted for the enforcement of payment of the principal of or interest on a debt security on or after the respective due dates. ( Section 508 of the Base Indenture ).

Street name and other indirect holders should consult their banks or brokers for information on how to give notice or direction to or make a request of the trustee and to make or cancel a declaration of acceleration.

We and Rio Tinto will furnish to the trustee every year a written statement of certain of our and Rio Tinto’s officers certifying that, to their knowledge, we and Rio Tinto are in compliance with the indenture and the debt securities, or else specifying any default. ( Section 1005 of the Base Indenture )

#### Regarding The Trustee
If an event of default occurs, or an event occurs that would be an event of default if the requirements for giving default notice or the default having to exist for a specific period of time were disregarded, the trustee may be considered to have a conflicting interest with respect to the debt securities for purposes of the Trust Indenture Act of 1939. In that case, the trustee may be required to resign as trustee under the applicable indenture and we or Rio Tinto would be required to appoint a successor trustee.
