(d) Exhibits.

Non-GAAP Supplemental Financial Measures

Funds From Operations (FFO)

We compute FFO in accordance with the White Paper on FFO
published by the National Association of Real Estate Investment
Trusts, or NAREIT, which defines FFO as net income (loss)
(determined in accordance with GAAP), excluding impairment
writedowns of investments in depreciable real estate and
investments in in-substance real estate investments, gains or
losses from debt restructurings and sales of depreciable
operating properties, plus real estate-related depreciation and
amortization (excluding amortization of

2

deferred financing costs), less distributions to non-controlling
interests and gains/losses from discontinued operations and after
adjustments for unconsolidated partnerships and joint ventures.
FFO is a widely recognized non-GAAP financial measure for REITs
that we believe, when considered with financial statements
determined in accordance with GAAP, is useful to investors in
understanding financial performance and providing a relevant
basis for comparison among REITs. In addition, FFO is useful to
investors as it captures features particular to real estate
performance by recognizing that real estate has generally
appreciated over time or maintains residual value to a much
greater extent than do other depreciable assets. Investors should
review FFO, along with GAAP net income, when trying to understand
an equity REITs operating performance. We present FFO because we
consider it an important supplemental measure of our operating
performance and believe that it is frequently used by securities
analysts, investors and other interested parties in the
evaluation of 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 of operations, the utility of FFO as a measure of
performance is limited. There can be no assurance that FFO
presented by us is comparable to similarly titled measures of
other REITs. FFO does not represent cash generated from operating
activities and should not be considered as an alternative to net
income (loss) determined in accordance with GAAP or to cash flow
from operating activities determined in accordance with GAAP. FFO
is not indicative of cash available to fund ongoing cash needs,
including the ability to make cash distributions. Although FFO is
a measure used for comparability in assessing the performance of
REITs, as the NAREIT White Paper only provides guidelines for
computing FFO, the computation of FFO may vary from one company
to another.

Modified Funds From Operations (Modified FFO)

Modified FFO adds back an adjustment for any above or
below-market ground lease amortization to traditionally defined
FFO. We consider this a useful supplemental measure in evaluating
our operating performance due to the non-cash accounting
treatment under GAAP, which stems from the third quarter 2014
acquisition of two option properties following our formation
transactions as they carry significantly below market ground
leases, the amortization of which is material to our overall
results. We present Modified FFO because we consider it an
important supplemental measure of our operating performance in
that it adds back the non-cash amortization of below-market
ground leases. There can be no assurance that Modified FFO
presented by us is comparable to similarly titled measures of
other REITs. Modified FFO does not represent cash generated from
operating activities and should not be considered as an
alternative to net income (loss) determined in accordance with
GAAP or to cash flow from operating activities determined in
accordance with GAAP. Modified FFO is not indicative of cash
available to fund ongoing cash needs, including the ability to
make cash distributions.

Core Funds From Operations (Core FFO)

Core FFO adds back to Modified FFO the following items:
acquisition expenses, deferred financing costs write-offs,
prepayment penalties, construction severance expenses and
acquisition break-up fee. The Company presents Core FFO because
it considers it an important supplemental measure of its
operating performance in that it excludes non-recurring items.
There can be no assurance that Core FFO presented by the Company
is comparable to similarly titled measures of other REITs. Core
FFO does not represent cash generated from operating activities
and should not be considered as an alternative to net income
(loss) determined in accordance with GAAP or to cash flow from
operating activities determined in accordance with GAAP. Core FFO
is not indicative of cash available to fund ongoing cash needs,
including the ability to make cash distributions. In future
periods, we may also exclude other items from Core FFO that we
believe may help investors compare our results.

Core Funds Available for Distribution (Core FAD)

In addition to Core FFO, we present Core FAD by (i)adding to Core
FFO non-real estate depreciation and amortization, the
amortization of deferred financing costs, amortization of debt
discounts and non-cash compensation expense and (ii)deducting
straight line rent, recurring second generation leasing
commissions, tenant improvements, prebuilts, capital
expenditures, furniture, fixtures equipment purchases,
amortization of debt premiums and above/below market rent
revenue. Core FAD is presented solely as a supplemental
disclosure that management believes provides useful information
regarding our ability to fund our dividends. Core FAD does not
represent cash generated from operating activities and should not
be considered as an alternative to net income (loss) determined
in accordance with GAAP or to cash flow from operating activities
determined in accordance with GAAP. Core FAD is not indicative of
cash available to fund ongoing cash needs, including the ability
to make cash distributions. There can be no assurance that Core
FAD presented by us is comparable to similarly titled measures of
other REITs.

Net Operating Income (NOI)

NOI is a non-GAAP financial measure of performance. NOI is used
by our management to evaluate and compare the performance of our
properties and to determine trends in earnings and to compute the
fair value of our properties as it is not affected by: (i)the
cost of funds of the property owner, (ii)the impact of
depreciation and amortization expenses as well as gains or losses
from the sale of operating real estate assets that are included
in net income computed in accordance with GAAP, (iii)acquisition
expenses and break-up fee, or (iv)general and administrative
expenses and other gains and losses that are specific to the
property owner. The cost of funds is eliminated from NOI because
it is specific to the particular financing capabilities and
constraints of the owner. The cost of funds is eliminated because
it is dependent on historical interest rates and other costs of
capital as well as past decisions made by us regarding the
appropriate mix of capital which may have changed or may change
in the future. Depreciation and amortization expenses as well as
gains or losses from the sale of operating real estate assets are
eliminated because they may not accurately represent the actual
change in value in our

4

office or retail properties that result from use of the
properties or changes in market conditions. While certain aspects
of real property do decline in value over time in a manner that
is reasonably captured by depreciation and amortization, the
value of the properties as a whole have historically increased or
decreased as a result of changes in overall economic conditions
instead of from actual use of the property or the passage of
time. Gains and losses from the sale of real property vary from
property to property and are affected by market conditions at the
time of sale which will usually change from period to period.
These gains and losses can create distortions when comparing one
period to another or when comparing our operating results to the
operating results of other real estate companies that have not
made similarly-timed purchases or sales. We believe that
eliminating these costs from net income is useful because the
resulting measure captures the actual revenue, generated and
actual expenses incurred in operating our properties as well as
trends in occupancy rates, rental rates and operating costs.
However, the usefulness of NOI is limited because it excludes
general and administrative costs, interest expense, depreciation
and amortization expense and gains or losses from the sale of
properties, and other gains and losses as stipulated by GAAP, the
level of capital expenditures and leasing costs necessary to
maintain the operating performance of our properties, all of
which are significant economic costs. NOI may fail to capture
significant trends in these components of net income which
further limits its usefulness. NOI is a measure of the operating
performance of our properties but does not measure our
performance as a whole. NOI is therefore not a substitute for net
income as computed in accordance with GAAP. This measure should
be analyzed in conjunction with net income computed in accordance
with. Other companies may use different methods for calculating
NOI or similarly titled measures and, accordingly, our NOI may
not be comparable to similarly titled measures reported by other
companies that do not define the measure exactly as we do.

EBITDA

We compute EBITDA as net income plus perpetual preferred unit
distributions, interest expense, income taxes, depreciation and
amortization and acquisition expenses. We present EBITDA because
we believe that EBITDA, along with cash flow from operating
activities, investing activities and financing activities,
provides investors with an additional indicator of its ability to
incur and service debt. EBITDA should not be considered as an
alternative to net income (determined in accordance with GAAP),
as an indication of our financial performance, as an alternative
to net cash flows from operating activities (determined in
accordance with GAAP), or as a measure of its liquidity.
