DecemberDecember 20062006 Forward Looking Statements ®

This presentation contains “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. All statements contained in this presentation that are not clearly historical in nature are forward-looking, and the words “anticipate,” “believe,” “expect,” “estimate,”, “forecast,” “project,” “should,” “plan,” and similar expressions are generally intended to identify forward-looking statements. Examples of these forward-looking statements include, but are not limited to: our belief that we will elect REIT tax status with our 2006 tax year; and our belief that our shares should trade at a tighter yield and faster growth rate than comparable companies. All forward-looking statements (including statements regarding future financial and operating results) involve risks, uncertainties and contingencies, many of which are beyond our control, which may cause actual results, performance, or achievements to differ materially from anticipated results, performance, or achievements. The forward-looking statements in this presentation regarding our anticipated results and performance as a REIT commencing in 2006 are subject to particular risks including, but not limited to: events that may require a change in the timing of our REIT election; our ability to position our assets in the most advantageous manner between the REIT and our taxable REIT subsidiary; material variance in the expected level of our cumulative earnings and profits or our projected dividend payout, and the implications of any such variance on our stock price; our ability to access the capital markets on attractive terms or at all to obtain the additional capital we will require to operate as a REIT; our management’s ability to operate our business in accordance with the complex rules and regulations governing REITs as necessary to ensure our qualification for and maintenance of our REIT status; potential changes in tax laws that could reduce the benefits we associate with the REIT election; and the relative attractiveness of our dividend payout as compared to other investment options should market interest rates continue to rise. More detailed information about factors we believe could cause our actual results, performance or achievements to differ materially from anticipated levels is contained in our filings with the SEC, including the sections captioned “Risk Factors” and “Business” in our Annual Report on Form 10-K as filed with the SEC on March 9, 2006. We are under no obligation to (and expressly disclaim any such obligation to) update or alter our forward-looking statements, whether as a result of new information, future events or otherwise.
