2.
We acknowledge and agree that:

under the Sale and Purchase Agreement, shall be US$270,999,519, which is the
aggregate amount due from KBS REIT Properties Ill LLC pursuant to the
Subscription Agreement and for its subscription of 79,545,000 units in Prime US
REIT via the placement tranche; and

(c)
in relation to clause 2.2 of the Set-Off Agreement, upon receipt by the Vendor
of the purchase price (as stated in the Sale and Purchase Agreement) less the
Relevant Amount, the Manager (i) shall discharge KBS REIT Properties Ill LLC
from, and have no further claim against, KBS REIT Properties Ill LLC in respect
of the payment of the subscription amounts due from KBS REIT Properties Ill LLC
for the subscription of the units in Prime US REIT under the Subscription
Agreement; and (ii) acknowledges and agrees that the payment of the subscription
amounts due from KBS REIT Properties Ill LLC for the subscription of the units

3.
This letter is governed by, and shall be construed in accordance with, the laws

non-exclusive jurisdiction of the courts of Singapore.

4.
This letter may be executed in any number of counterparts, each of which, when

mutandis, as if expressly incorporated herein.
