Amended and Restated Agreement of Limited Partnership>

In connection with the Disposition, on December 8, 2016, the

entered into the Amended and Restated Agreement of Limited
Partnership of Pillarstone OP (as amended and restated, the Amended
and Restated Agreement of Limited Partnership). to the Amended and
Restated Agreement of Limited Partnership, subject to certain
protective rights of the limited partners described below, the
general partner, has full, exclusive and complete responsibility
and discretion in the management and control of Pillarstone OP,
including the ability to cause Pillarstone OP to enter into certain
major transactions including a merger of Pillarstone OP or a sale
of substantially all of the assets of Pillarstone OP. The limited
partners have no power to remove the general partner without the
general partner’s consent. In addition, to the Amended and
Restated Agreement of Limited Partnership, the general partner may
not conduct any business without the consent of a majority of the
limited partners other than in connection with certain actions
described therein.

The Amended and Restated Agreement of Limited Partnership
designates two classes of units of limited partnership interest in
Pillarstone OP: the Pillarstone OP Units and LTIP units. In
general, LTIP units are similar to the Pillarstone OP Units and
will receive the same quarterly per-unit profit distributions as
the Pillarstone OP Units. The rights, privileges, and obligations
related to each series of LTIP units will be established at the
time the LTIP units are issued. As profits interests, LTIP units
initially will not have full parity, on a per-unit basis, with
Pillarstone OP Units with respect to liquidating distributions.
Upon the occurrence of specified events, LTIP units can over time
achieve full parity with the Pillarstone OP Units and therefore
accrete to an economic value for the holder equivalent to
Pillarstone OP Units. If such parity is achieved, vested LTIP units
may be converted on a one-for-one basis into Pillarstone OP Units,
which in turn are redeemable by the holder for cash or, at
Pillarstones election, exchangeable for Pillarstone Common Shares
on a one-for-one basis.
