   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;Noncontrolling interests in the accompanying financial statements represent the interests of the
   common and preferred units in Liberty Property Limited Partnership not held by the Trust. In
   addition, noncontrolling interests include third-party ownership interests in consolidated joint
   venture investments.
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;&lt;b&gt;Common units&lt;/b&gt;
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;The common units outstanding as of September&amp;#160;30, 2010 have the same economic characteristics as
   common shares of the Trust. The 3,943,224 outstanding common units share proportionately in the
   net income or loss and in any distributions of the Operating Partnership. The common units of the
   Operating Partnership not held by the Trust are redeemable at any time at the option of the holder.
   The Trust, as the sole general partner of the Operating Partnership, may at its option elect to
   settle the redemption in cash or through the exchange on a one-for-one basis with unregistered
   common shares of the Trust. The market value of the 3,943,224 outstanding common units based on
   the closing price of the common shares of the Company at September&amp;#160;30, 2010 was $125.8&amp;#160;million.
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;&lt;b&gt;Preferred units&lt;/b&gt;
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;The Company has outstanding the following cumulative redeemable preferred units of the Operating
   Partnership (the &amp;#8220;Preferred Units&amp;#8221;):
