Alternative Minimum Tax

Alternative minimum tax adjustments are to be apportioned between a real estate investment trust ("REIT") and its shareholders under Internal Revenue Code Section 59(d). Although regulations have not yet been issued under that provision, based on regulations issued pursuant to a similar provision of prior law and the legislative history of the current provision, it appears that such alternative minimum tax adjustments are to be apportioned to a REIT's shareholders to the extent that the REIT distributes its regular taxable income. It is the Company's policy to distribute all of its regular taxable income and accordingly, all of the Company's alternative minimum tax adjustments are being apportioned to the Company's shareholders.

The Company has determined that -1.3213% of each distribution to its shareholders for the tax year ended December 31, 2006 consists of alternative minimum tax adjustments (i.e., for each $1 of dividend reportable by a shareholder, -1.3213 cents represents an alternative minimum tax adjustment). To determine your share of the Company's alternative minimum tax adjustments, multiply the aggregate dollar amount of your reportable 2006 dividends from the Company (the sum of the amounts shown in Boxes 1a and 2a of the Company's 2006 Form 1099-DIV) times -1.3213%.

If you are an individual, please refer to Internal Revenue Service Form 6251, Alternative Minimum Tax--Individuals. Your share of alternative minimum tax adjustments should be input as a positive amount in Part I, Line 17 (depreciation on assets placed in service after 1986). If you are a corporation, please refer to Internal Revenue Service Form 4626, Alternative Minimum Tax--Corporations. Your share of alternative minimum tax adjustments should be input as a positive amount in Line 2, letter "a" (depreciation of post-1986 property).

If you have questions, please consult your tax advisor for further guidance.
