foreign laws and regulations, including those related to taxation and real estate ownership and operation,
increased interest rates and operating costs; inability to acquire new properties (including those we are in the
process of acquiring); our failure to obtain necessary outside financing; increased construction costs; decreased
rental rates or increased vacancy rates; difficulties in identifying properties to acquire and completing
acquisitions; our failure to successfully operate acquired properties and operations; our failure to maintain our
status as a REIT; possible adverse changes to tax law; environmental uncertainties and risks related to natural

Definition of Non-GAAP Financial Measures
This presentation includes certain non-GAAP financial measures that management believes are helpful in understanding our business, as
further described below. Our definition and calculation of non-GAAP financial measures may differ from those of other REITs, and,
therefore, may not be comparable. The non-GAAP financial measures should not be considered an alternative to net income or any other
GAAP measurement of performance and should not be considered an alternative to cash flows from operating, investing or financing
activities as a measure of liquidity.
Net Operating Income (NOI)
NOI represents rental revenue and tenant reimbursement revenue less rental property operating and maintenance, property taxes and
insurance expenses (as reflected in statement of operations).  NOI is commonly used by stockholders, company management and
industry analysts as a measurement of operating performance of the company’s rental portfolio. However, because NOI excludes
depreciation and amortization and captures neither the changes in the value of our properties that result from use or market conditions,
nor
the
level
of
capital
expenditures
and
leasing
commissions
necessary
to
maintain
the
operating
performance
of
our
properties,
all
of
which have real economic effect and could materially impact our results from operations, the utility of NOI as a measure of our
performance is limited.  Other REITs may not calculate NOI in the same manner we do and, accordingly, our NOI may not be comparable
to such other REITs’
NOI.  Accordingly, NOI should be considered only as a supplement to net income as a measure of our performance.
Funds from Operations (FFO)
We calculate Funds from Operations, or FFO, in accordance with the standards established by the National Association of Real Estate
Investment Trusts, or NAREIT.  FFO represents net income (loss) (computed in accordance with GAAP), excluding gains (or losses)
from sales of property, real estate related depreciation and amortization (excluding amortization of deferred financing costs) and after
adjustments
for
unconsolidated
partnerships
and
joint
ventures.
Management
uses
FFO
as
a
supplemental
performance
measure
because, in excluding real estate related depreciation and amortization and gains and losses from property dispositions, it provides a
performance measure that, when compared year over year, captures
trends in occupancy rates, rental rates and operating costs.  We
also believe that, as a widely recognized measure of the performance of REITs, FFO will be used by investors as a basis to compare our
operating performance with that of other REITs.  However, because FFO excludes depreciation and amortization and captures neither
the changes in the value of our properties that result from use or market conditions, nor the level of capital expenditures and leasing
commissions necessary to maintain the operating performance of our properties, all of which have real economic effect and could
materially impact our results from operations, the utility of FFO as a measure of our performance is limited.  Other REITs may not
calculate
FFO
in
accordance
with
the
NAREIT
definition
and,
accordingly,
our
FFO
may
not
be
comparable
to
such
other
REITs’
FFO. 
Accordingly, FFO should be considered only as a supplement to net income as a measure of our performance.

Definition of Non-GAAP Financial Measures
(continued)
EBITDA and Adjusted EBITDA 
We believe that earnings before interest, income taxes, depreciation and amortization, or EBITDA and Adjusted EBITDA (as defined
below), are useful supplemental performance measures because they allow investors to view our performance without the impact of
noncash
depreciation and amortization or the cost of debt and with respect to Adjusted EBITDA preferred dividends and minority
interests. Adjusted EBITDA is EBITDA excluding minority interests and preferred stock dividends. In addition, we believe EBITDA and
adjusted EBITDA are frequently used by securities analysts, investors and other interested parties in the evaluation of REITs. Because
EBITDA and adjusted EBITDA are calculated before recurring cash charges including interest expense and income taxes, and are not
adjusted for capital expenditures or other recurring cash requirements of our business, their utility as a measure of our performance is
limited. Accordingly, EBITDA and Adjusted EBITDA should be considered only as supplements to net income (computed in accordance
with GAAP) as a measure of our financial performance. Other equity REITs may calculate EBITDA and Adjusted EBITDA differently than
we
do;
accordingly,
our
EBITDA
and
Adjusted
EBITDA
may
not
comparable
to
such
other
REITs’
EBITDA
and
Adjusted
EBITDA.
Each of FFO,NOI, and Adjusted EBITDA exclude items that have real economic effect and could materially impact our results from
operations, and therefore the utility of FFO, NOI, and Adjusted EBTIDA as a measure of our performance is limited.

herein
