   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;Operating ground lease expense incurred by the Company during the years ended December&amp;#160;31,
   2010, 2009 and 2008 amounted to $434,000, $460,000 and $486,000, respectively.
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;&lt;b&gt;Legal Matters&lt;/b&gt;
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;As noted in previous filings, as a result of the Company&amp;#8217;s acquisition of Republic Property Trust
   in October, 2007 the Company was substituted as a party to certain ongoing litigation (the
   &amp;#8220;Republic Litigation&amp;#8221;). The Republic Litigation has been settled, and the settlement has not had, and will not have,
   a material impact on the Company's financial position and results of operations for any period.
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;From time to time, the Company is a party to a variety of legal proceedings, claims and assessments
   arising in the normal course of business. The Company regularly assesses the liabilities and
   contingencies in connection with these matters based on the latest available information. For
   those matters where it is probable that the Company has incurred or will incur a loss and the loss
   or range of loss can be reasonably estimated, the estimated loss is accrued and charged to income
   in the Company&amp;#8217;s consolidated financial statements. In other cases, because of the uncertainties
   related to both the probable outcome and amount or range of potential loss, a reasonable estimate
   of liability, if any, cannot be made. The Company has reviewed the liabilities and contingencies
   in connection with these matters. As of December&amp;#160;31, 2010, the Company believes that there are no
   legal proceedings, claims or assessments that are expected to have a material adverse effect on the
   Company&amp;#8217;s business or financial statements.
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;&lt;b&gt;Other&lt;/b&gt;
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;The Company is obligated to make additional capital contributions to unconsolidated joint ventures
   of $4.1&amp;#160;million. The Company has not guaranteed any of the principal balance of the debt of the
   unconsolidated joint ventures.
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;The Company has guaranteed the interest payments under its mortgage loan for its unconsolidated
   joint venture Blythe Valley JV Sarl for a maximum of $2.1&amp;#160;million.
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;The Company has letter of credit obligations of $934,000 related to development requirements. The
   Company believes that it is remote that there will be a draw upon these letter of credit
   obligations.
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;The Company is obligated to pay for tenant improvements not yet completed
   for a maximum of $35.7&amp;#160;million.
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;The Company maintains cash and cash equivalents at financial institutions. The combined account
   balances at each institution typically exceed FDIC insurance coverage and, as a result, there is a
   concentration of credit risk related to amounts on deposit in excess of FDIC insurance coverage.
   The Company believes the risk is not significant.

   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;Operating ground lease expense incurred by the Company during the years ended December&amp;#160;31,
   2010, 2009 and 2008 amounted to $434,000, $460,000 and $486,000, respectively.
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;&lt;b&gt;Legal Matters&lt;/b&gt;
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;As noted in previous filings, as a
   result of the Company&amp;#8217;s acquisition of Republic Property Trust
   in October, 2007 the Company was substituted as a party to certain ongoing litigation (the
   &amp;#8220;Republic Litigation&amp;#8221;). The Republic Litigation has been settled, and the settlement
   has not had, and will not have, a material impact on the Company&amp;#8217;s financial position and
   results of operations for any period.
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;From time to time, the Company is a party to a variety of legal proceedings, claims and assessments
   arising in the normal course of business. The Company regularly assesses the liabilities and
   contingencies in connection with these matters based on the latest available information. For
   those matters where it is probable that the Company has incurred or will incur a loss and the loss
   or range of loss can be reasonably estimated, the estimated loss is accrued and charged to income
   in the Company&amp;#8217;s consolidated financial statements. In other cases, because of the uncertainties
   related to both the probable outcome and amount or range of potential loss, a reasonable estimate
   of liability, if any, cannot be made. The Company has reviewed the liabilities and contingencies
   in connection with these matters. As of December&amp;#160;31, 2010, the Company believes that there are no
   legal proceedings, claims or assessments that are expected to have a material adverse effect on the
   Company&amp;#8217;s business or financial statements.
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;&lt;b&gt;Other&lt;/b&gt;
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;The Company is obligated to make
   additional capital contributions to unconsolidated joint ventures
   of $4.1&amp;#160;million. The Company has not guaranteed any of the principal balance of the debt of
   the unconsolidated joint ventures.
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;The Company has guaranteed the
   interest payments under its mortgage loan for its unconsolidated
   joint venture Blythe Valley JV Sarl for a maximum of $2.1&amp;#160;million.
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;The Company has letter of credit
   obligations of $934,000 related to development requirements. The
   Company believes that it is remote that there will be a draw upon these letter of credit
   obligations.
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;The Company is obligated to pay for
   tenant improvements not yet completed for a maximum of $35.7&amp;#160;million.
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;The Company maintains cash and cash equivalents at financial institutions. The combined account
   balances at each institution typically exceed FDIC insurance coverage and, as a result, there is a
   concentration of credit risk related to amounts on deposit in excess of FDIC insurance coverage.
   The Company believes the risk is not significant.
