#### Restrictive Covenants

#### Restrictions on Liens
Some of our or Rio Tinto’s property may be subject to a mortgage or other legal mechanism that gives our and Rio Tinto’s lenders preferential rights in that property over other lenders, including the holders of the debt securities, or over our and Rio Tinto’s general creditors if we fail to pay them back. These preferential rights are called liens. We promise that we will not become obligated on any new debt for borrowed money that is secured by a lien on any of our or Rio Tinto’s properties, unless we or Rio Tinto grant an equivalent or higher-ranking lien on the same property to the holders of the debt securities.

Consolidated net worth plus minorities is defined in the indenture as a measure of the net worth of Rio Tinto that includes amounts attributable to the outside interests in the accounting subsidiaries of Rio Tinto. ( Sections 101 and 1007 of the Base Indenture ) At the date of this prospectus, a substantial portion of the consolidated assets of Rio Tinto is held by their subsidiaries and thus would not be subject to this restriction on liens.
