 are taxed on a net-incomebasis at the regular rates and in the manner applicable to U.S. persons. You generally will be required to provide to the applicable withholding agent a properly executed IRS Form W-8ECI(or a suitable substitute form) in order to claim an exemption from, or reduction in, U.S. federal withholding tax. In addition, a “branch profits tax” may be imposed at a 30% rate (or a reduced rate under an applicable income tax treaty) on a foreign corporation’s effectively connected earnings and profits for the taxable year, as adjusted for certain items. Because distributions made in the form of shares of our common stock will not give rise to any cash from which any applicable withholding tax could be satisfied, if we (or an applicable withholding agent) pay withholding on behalf of a non-U.S.holder (because such non-U.S.holder failed to establish an exemption from dividend withholding), we may, at our option, set off such payments against, or an applicable withholding agent may withhold such taxes from, shares of common stock payable to such holder or current or subsequent payments of cash, or require alternative arrangements (e.g., deposit for taxes prior to delivery of such shares or of conversion consideration).

 year of the disposition and certain other conditions are satisfied; or                                          |

A non-U.S.holder described in the first bullet point above generally will be subject to U.S. federal income tax on the net gain derived from the sale in the same manner as a U.S. holder. A non-U.S.holder that is a foreign corporation will be subject to tax on gain under regular graduated U.S. federal income tax rates and, in addition, may be subject to a branch profits tax at a
