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:

    affect office property and data center demand and rents, tenant
    creditworthiness, interest rates, financing availability and property
    values;
  *adverse changes in the real estate markets including, among other things,
    increased competition with other companies;
  *governmental actions and initiatives, including risks associated with the
    impact of a government shutdown or budgetary reductions or impasses, such
    as a reduction in rental revenues, non-renewal of leases, and/or a
    curtailment of demand for additional space by the Company's strategic
    customers;
  *the Company’s ability to borrow on favorable terms;
  *risks of real estate acquisition and development activities, including,
    among other things, risks that development projects may not be completed
    on schedule, that tenants may not take occupancy or pay rent or that
    development or operating costs may be greater than anticipated;
  *the Company’s ability to sell properties included in its Strategic
    Reallocation Plan;
  *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 the Company’s plans for properties or views of market economic
    conditions or failure to obtain development rights, either of which could
    result in recognition of significant impairment losses;
  *the Company’s ability to satisfy and operate effectively under Federal
    income tax rules relating to real estate investment trusts and
    partnerships;
  *the Company's ability to achieve projected results;
  *the dilutive effects of issuing additional common shares; and
  *environmental requirements.
