S-3 3

CERTAIN UNITED STATES FEDERAL INCOME TAX CONSEQUENCES The following discussion summarizes certain material U.S. federal income tax consequences of acquiring, owning and disposing of the Notes. The discussion is based upon the Code; current, temporary and proposed U.S. Treasury Regulations issued thereunder (the “Treasury Regulations”); the legislative history of the Code; Internal Revenue Service (“IRS”) rulings, pronouncements, interpretations and practices; and judicial decisions now in effect, all of which are subject to change at any time. Any such change may be applied retroactively in a manner that could adversely affect a holder of the Notes. This discussion is limited to persons purchasing the Notes for cash at original issue and at the offering price on the cover page of this prospectus supplement. Furthermore, this discussion assumes that each holder holds the Notes as “capital assets” within the meaning of Section 1221 of the Code (generally, property held for investment). It does not reflect every possible tax outcome or consequence that could result from acquiring, owning or disposing of the Notes. For example, special rules not discussed here may apply to you if you are:

| • |     | a broker-dealer, dealer or trader in securities or currencies; |

| • |     | a controlled foreign corporation; |

| • |     | a passive foreign investment company; |

| • |     | an S corporation; |

| • |     | a bank, thrift or other financial institution; |

| • |     | a regulated investment company, a real estate investment trust or other financial conduit entity (or shareholder of such entity); |

| • |     | an accrual method taxpayer subject to special tax accounting rules as a result of its use of financial statements; |
