   &lt;div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 8%"&gt;As of September&amp;#160;30, 2010, the mortgage loans receivable had an aggregate principal balance of
   $259.2&amp;#160;million and are reflected in our consolidated balance sheets net of aggregate deferred gains
   totaling $20.3&amp;#160;million, with individual outstanding principal balances ranging from $0.7&amp;#160;million to
   $83.1&amp;#160;million and maturities ranging from 2010 to 2031.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 8%"&gt;During the nine months ended September&amp;#160;30, 2010, we funded three mortgage loans secured by 27
   medical office buildings, one assisted and independent living facility and one skilled nursing
   facility in the amount of $117.3&amp;#160;million. In connection with the funding of the mortgage loan
   secured by the skilled nursing facility, we agreed to fund up to $10.9&amp;#160;million to expand the
   facility. No amounts have been funded under the agreement at September&amp;#160;30, 2010.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 8%"&gt;During the nine months ended September&amp;#160;30, 2010, we also funded $6.8&amp;#160;million and $52.8&amp;#160;million
   under loans to our consolidated joint ventures with PMB Gilbert LLC and PMB Pasadena LLC,
   respectively (see Note 5). As we consolidate these joint ventures, these balances have been
   eliminated for purposes of our consolidated financial statements.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 8%"&gt;During the nine months ended September&amp;#160;30, 2010, we sold the assisted living portion of a
   continuing care retirement community for which we had an existing mortgage loan secured by the
   skilled nursing portion of such continuing care retirement community to the tenant of the facility.
   For facility count purposes, this was previously accounted for in real estate properties as a
   continuing care retirement community (see Note 3). We provided financing of $6.5&amp;#160;million related to
   the sale, including the concurrent repayment of a $0.7&amp;#160;million unsecured loan which had previously
   been included in the caption &amp;#8220;Other assets&amp;#8221; on our consolidated balance sheets, and funded an
   additional $0.3&amp;#160;million subsequent to the sale.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 8%"&gt;During the nine months ended September&amp;#160;30, 2010, we transferred and assigned our controlling
   interest in Partnership A to our partner in exchange for our partner&amp;#8217;s noncontrolling interest in
   Partnership B (see Note 3). We had previously provided a mortgage loan in the amount of $5.2
   million to Partnership A which was assigned to our partner as part of the exchange transaction.
   Fair value at the exchange transaction date was determined based on estimates considering factors
   and assumptions including historical operating results, available market information and known
   trends and market/economic conditions. The exchange transaction resulted in a $1.0&amp;#160;million gain
   which was deferred.

   &lt;div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 8%"&gt;As of February&amp;#160;1, 2010, we acquired the multi-tenant medical office building which served as
   collateral for our $47.5&amp;#160;million mortgage loan from a related party, and as a result, the loan was
   retired (see Notes 5 and 18).
