 is treated as a partnership for U.S. federal income tax purposes. Interest on the Notes.Subject to the discussions below under “—Backup Withholding, Information Reporting and Other Reporting Requirements,” U.S. federal withholding tax will not apply to any payment of interest on a note to a non-U.S.holder if the interest qualifies for the “portfolio interest exemption.” This will be the case provided that the non-U.S.holder:

| • |     | does not actually or constructively own 10% or more of the total combined voting power of all classes of our 
 stock entitled to vote;                                                                                      |

| • |     | is not a controlled foreign corporation that is related directly or constructively to us through stock ownership; 
 and                                                                                                               |

| • |     | either (a) provides its name and address, and certifies, under penalties of perjury, that it is not a U.S.                                       
 person as defined under the Code, which certification may be made on an IRS Form W-8BEN, W-8BEN-E or other appropriate form, or                  
 (b) holds its notes through various foreign intermediaries and satisfies the certification requirements of applicable U.S. Treasury regulations. |

Special certification and other rules apply to certain non-U.S.holders that are entities rather than individuals, particularly entities treated as partnerships for U.S. federal income tax purposes and certain other flow through entities, and to non-U.S.holders acting as (or holding notes through) intermediaries. If the portfolio interest exemption does not apply, payments of interest will be subject to U.S. federal withholding tax at a 30% tax rate, unless the non-U.S.holder provides us with a properly executed: (1) IRS Form W-8BEN, W-8BEN-Eor other appropriate form, claiming an exemption from or reduction in withholding under the benefit of an income tax treaty or (2) IRS Form W-8ECI,or successor form, stating that interest paid on the S-57

note is not subject to withholding tax because it is effectively connected with its conduct of a trade or business in the United States.

If a non-U.S. holder is engaged in a trade or business in the United States and interest on a note is
effectively connected with the conduct of that trade or business (and, if required under an applicable income tax treaty, is attributable to a U.S. permanent establishment or fixed base maintained by the
non-U.S. holder), such non-U.S
