income tax treaty reduces or eliminates such tax. See “Material United States Federal Income Tax Considerations—United States Holders—Purchase Contracts” and “Material United States Federal Income Tax Considerations—Non-United States Holders—United States Federal Withholding Tax.”

The Company will report contract adjustment payments as ordinary income and the Company will withhold tax on contract adjustment payments made to non-United States holders.

The Company intends to treat contract adjustment payments as taxable ordinary income to a United States holder (as defined under “Material United States Federal Income Tax Considerations” below) when received or accrued, in accordance with the United States holder’s regular method of tax accounting. The Company intends to treat any contract adjustment payments paid to a non-United States holder as payments generally subject to withholding tax at a 30% rate, unless an income tax treaty reduces or eliminates such tax and the holder satisfies the relevant certification requirements or such payments are “effectively connected income” of such non-United States Holder. See “Material United States Federal Income Tax Considerations—United States Holders—Purchase Contracts” and “Material United States Federal Income Tax Considerations—Non-United States Holders—United States Federal Withholding Tax.” Persons considering the purchase of Equity Units should consult their tax advisors concerning the possible alternative characterization and tax treatment of Equity Units and the contract adjustment payments.

The Company intends to use a portion of the net proceeds of this offering to repurchase a portion of the outstanding Existing Convertible Senior Notes in privately negotiated transactions. The Company may also repurchase Existing Convertible Senior Notes following the completion of this offering. Any repurchases of the Existing Convertible Senior Notes are likely to affect the market price of the Common Stock and the reference price of the stock purchase contract component of the Equity Units. The Company expects that holders of the Existing Convertible Senior Notes that sell their Existing Convertible Senior Notes to the Company in any note repurchase transaction may enter into or unwind various derivatives with respect to the Common Stock and/or purchase or sell shares of the Common Stock in the market to hedge their exposure in connection with these transactions. In particular, the Company expects that many holders of the Existing Convertible Senior Notes employ a
