United States Federal Taxation

In the opinion of our counsel, Davis Polk & Wardwell LLP, the notes will be treated as debt instruments and are expected to be issued with original issue discount for U.S. federal income tax purposes, as discussed under “United States Federal Taxation—Tax Consequences to U.S. Holders—Notes—Discount Notes” in the accompanying prospectus supplement.

For a description of the material U.S. federal income tax consequences and certain estate tax consequences of the purchase, ownership and disposition of the notes, please refer to “United States Federal Taxation” in the accompanying prospectus supplement.

Both U.S. investors and non-U.S. investors should consult their tax advisers regarding all aspects of the U.S. federal tax consequences of an investment in the notes, as well as any tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.

The discussion in the preceding paragraphs under “United States Federal Taxation” and the discussion contained in the section entitled “United States Federal Taxation” in the accompanying prospectus supplement, insofar as they purport to describe provisions of U.S. federal income tax laws or legal conclusions with respect thereto, constitute the full opinion of Davis Polk & Wardwell LLP regarding the material U.S. federal tax consequences of an investment in the notes.
