Risk Factors
An
investment
in
shares
of
Senior
Common
Stock
involves
substantial
risks.
You
should
purchase
our
securities
only
if
you
can
afford
a
complete
loss
of
your
investment.
Please
read
and
consider
the
risk
factors
in
the
prospectus
supplement
and
prospectus
before
purchasing
any
securities.
The
most
significant
risk
factors
include:
Risks Relating to Our Senior Common Stock and this Offering:
There is no established public trading market for shares of Senior Common Stock, and we have no plans to list these shares on
a national securities exchange.
We established the offering price of shares of Senior Common Stock on an arbitrary basis, and, as a result, the actual value of
your investment may be substantially less than what you pay.
The calculation of the Exchange Ratio could result in a deterrent to your exchanging shares of Senior Common Stock for
shares of Listed Common Stock if shares of Listed Common Stock are trading at lower levels at the time that you desire to
exchange your shares.
Your
ability
to
redeem
shares
of
Senior
Common
Stock
pursuant
to
our
share
redemption
program
is
limited
to
the
proceeds
generated by our distribution reinvestment plan, and the share redemption program may be amended, suspended or terminated
by our Board at any time without stockholder approval.
If you do not agree with the decisions of our Board, then you will not be able to influence changes in our policies and
operations
because
holders
of
shares
of
Senior
Common
Stock
will
generally
have
no
voting
rights.
Our charter contains restrictions on the ownership and transfer of shares of our capital stock, and these restrictions may inhibit
your ability to sell your shares
of
Senior Common Stock promptly, or at all.
Our Dealer Manager is one of our affiliates, and, therefore, an investor in shares of Senior Common Stock would not have the
benefit of an independent underwriter who has performed an independent due diligence review.
Highly
leveraged
tenants
and
borrowers
may
be
unable
to
pay
rent
or
make
mortgage
payments,
which
could
adversely
affect
our cash available to make distributions to holders of our Senior Common Stock.
3

Risk Factors (continued)
Risks Relating to Our Company and Our Operations
Our business strategy relies heavily on external financing, which may expose us to risks associated with
leverage such as restrictions on additional borrowing and payment of distributions to stockholders, risks
associated
with
balloon
payments,
and
risk
of
loss
of
our
equity
upon
foreclosure.
We are subject to certain risks associated with real estate ownership and lending which could reduce the
value of our investments, including but not limited to, changes in the general economic climate; changes in
local conditions such as an oversupply of space or reduction in demand for real estate; changes in interest
rates and the availability of financing; competition from other available space; and changes in laws and
governmental regulations, including those governing real estate usage, zoning and taxes.
Our
properties
may
be
subject
to
impairment
charges,
which
could
adversely
affect
our
results
of
operations and FFO.
Illiquidity
of
real
estate
investments
may
make
it
difficult
for
us
to
sell
properties
in
response
to
market
conditions
and
our
properties
may
include
special
use
and
single
or
multi-tenant
properties
that
may
be
difficult to sell or re-lease upon tenant defaults or early lease terminations which could harm our financial
condition and ability to make distributions.
Our
real
estate
investments
have
a
limited
number
of
tenants,
many
of
which
are
small-
and
medium-sized
businesses, and are concentrated in a limited number of industries, which subjects us to an increased risk of
significant
loss
if
any
one
of
these
tenants
is
unable
to
pay
or
if
particular
industries
experience
downturns.
4

Risk Factors (continued)
Risks
Relating
to
Our
Company
and
Our
Operations
(continued
from
previous
slide)
We may be unable to renew leases, lease vacant space or re-lease space as leases expire, which could
adversely affect our business and our ability to make distributions to our stockholders.
We
may
enter
into
sale-leaseback
transactions,
whereby
we
would
purchase
a
property
and
then
lease
the
same
property
back
to
the
person
from
whom
we
purchased
it.
If
a
sale-leaseback
transaction
is
re-
characterized in a tenant’s bankruptcy proceeding, our financial condition could be adversely affected.
We are dependent upon our key management personnel, who are employed by our Adviser, for our future
success.  The departure of any of our executive officers or key employees could have a material adverse
effect on our ability to implement our business strategy and to achieve our investment objectives.
Our
success
depends
on
the
performance
of
our
Adviser
and
if
our
Adviser
makes
inadvisable
investment
or management decisions, our operations could be materially adversely impacted.
We may have conflicts of interest with our Adviser and other affiliates, including but not limited to the
following conflicts: (i) our Adviser may realize substantial compensation on account of its activities on our
behalf,
and
may,
therefore,
be
motivated
to
approve
acquisitions
solely
on
the
basis
of
increasing
compensation to itself; (ii) we may experience competition with our affiliates for financing transactions;
(iii) our Adviser may earn fee income from our borrowers or tenants; and (iv) our Adviser and other
affiliates could compete for the time and services of our officers and directors.
If
we
fail
to
qualify
as
a
REIT,
our
operations
and
dividends
to
stockholders
would
be
adversely
impacted.
To the extent that our distributions represent a return of capital for tax purposes, you could recognize an
increased capital gain upon a subsequent sale of your stock.
