Definitive Agreement.</B>

<P style="font-size: 10pt; text-indent: 4%" align="left">Prime Group Realty
Trust (the &#8220;<U>Company</U>&#8221;) issued a press release today
announcing that on September&nbsp;3, 2008, Younan Properties, Inc.
(&#8220;<U>Purchaser</U>&#8221;) became obligated to purchase 180 North LaSalle
Street, Chicago, Illinois (the &#8220;<U>Property</U>&#8221;), from the
subsidiary of the Company (&#8220;<U>Seller</U>&#8221;) that owns the Property.

<P style="font-size: 10pt; text-indent: 4%" align="left">The gross purchase
price for the Property is $124.0&nbsp;million, subject to certain pro-rations,
credits and adjustments. The Purchaser has deposited $5.0&nbsp;million (the
&#8220;<U>Earnest Money</U>&#8221;) in escrow to secure its obligation to
purchase the Property, which became nonrefundable on September&nbsp;3, 2008
except upon the occurrence of certain customary events, such as a default by
Seller or the failure of Seller to deliver certain satisfactory tenant estoppel
certificates. The Company currently estimates that after closing adjustments,
closing costs and necessary payments to defease the existing first mortgage
loan on the Property, the Seller will receive net proceeds of approximately
$53.7 million.

<P style="font-size: 10pt; text-indent: 4%" align="left">The Purchaser has
completed its due diligence inspection of the Property and is obligated to
purchase the Property subject to certain customary conditions contained in the
purchase agreement. It is currently contemplated that the closing will occur in
the middle of October. In the event that the Purchaser defaults on its
obligations to purchase the Property, Seller&#8217;s sole remedy is to receive
the Earnest Money as liquidated damages.

<P style="font-size: 10pt" align="left">There can be no assurances that all of
the conditions to closing will be satisfied and that this transaction will
actually close, or that if it does close, it will close pursuant to the
foregoing timetable or the terms set forth in this Form 8-K. This Form 8-K
contains certain forward-looking statements within the meaning of the Private
