#### Default and Related Matters

#### Ranking
The debt securities are not secured by any of our property or assets nor Rio Tinto’s property or assets. Accordingly, holders of debt securities are unsecured creditors of Rio Tinto. The debt securities are not subordinated to any of our or Rio Tinto’s other debt obligations and therefore they rank equally with all our and Rio Tinto’s other unsecured and unsubordinated indebtedness.

#### Events of Default
Holders will have special rights if an event of default occurs and is not cured, as described later in this subsection.

•

Neither we, Rio Tinto plc nor Rio Tinto Limited pay the principal or any premium on a debt security and, in the case of technical or administrative difficulties, only if such failure to pay persists for more than three business days.

•

Neither we, Rio Tinto plc nor Rio Tinto Limited pay interest or any additional amounts on a debt security within 30 days of its due date.

The notice must be sent by either the trustee or holders of 25% of the principal amount of debt securities of the affected series.

•

We, Rio Tinto plc or Rio Tinto Limited file for bankruptcy or certain other events in bankruptcy, insolvency or reorganization occur, unless, in the case of Rio Tinto plc or Rio Tinto Limited, the reorganization is a voluntary winding up carried out in accordance with English or Australian statutory requirements as applicable and which results in a legal entity that is liable under the guarantees, and which owns
