This press release may contain "forward-looking" statements, as defined in Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934, that are based on the Company's current expectations, estimates and projections about future events and financial trends affecting the Company. Forward-looking statements can be identified by the use of words such as "may," "will," "should," "could," "believe," "anticipate," "expect," "estimate," "plan" or other comparable terminology. Forward-looking statements are inherently subject to risks and uncertainties, many of which the Company cannot predict with accuracy and some of which the Company might not even anticipate. Accordingly, the Company can give no assurance that these expectations, estimates and projections will be achieved. Future events and actual results may differ materially from those discussed in the forward-looking statements.

Important factors that may affect these expectations, estimates, and projections include, but are not limited to:

        things, affect office property demand and rents, tenant
        creditworthiness, interest rates and financing availability;

        things, increased competition with other companies;

        development or operating costs may be greater than anticipated;
    --  risks of investing through joint venture structures, including risks
        that the Company's joint venture partners may not fulfill their
        financial obligations as investors or may take actions that are
        inconsistent with the Company's objectives;
    --  changes in our plans or views of market economic conditions or failure
        to obtain development rights, either of which, could result in
        recognition of impairment losses;
    --  our ability to satisfy and operate effectively under federal income tax
        rules relating to real estate investment trusts and partnerships;
    --  governmental actions and initiatives; and
