   &lt;div align="left" style="font-size: 10pt; margin-top: 10pt"&gt;&lt;b&gt;4. Mortgage Loans Receivable&lt;/b&gt;
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%"&gt;At March&amp;#160;31, 2010, we held 15 mortgage loans receivable secured by 26 medical office
   buildings, 16 skilled nursing facilities, nine assisted and independent living facilities, one
   continuing care retirement community and one land parcel. At March&amp;#160;31, 2010, the mortgage loans
   receivable had an aggregate principal balance of $216.6&amp;#160;million and are reflected in our
   consolidated balance sheets net of aggregate deferred gains totaling $19.3&amp;#160;million, with individual
   outstanding principal balances ranging from $0.7&amp;#160;million to $80.1&amp;#160;million and maturities ranging
   from 2010 to 2024.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%"&gt;During the three months ended March&amp;#160;31, 2010, we funded one mortgage loan secured by 26
   medical office buildings in the amount of $80.1&amp;#160;million.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%"&gt;During the three months ended March&amp;#160;31, 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: 4%"&gt;During the three months ended March&amp;#160;31, 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 $0.2&amp;#160;million subsequent to the sale.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%"&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).
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%"&gt;In 2009, we entered into an agreement with one of our triple-net tenants, Brookdale Senior
   Living, Inc. (&amp;#8220;Brookdale&amp;#8221;), under which we became a lender with a commitment of $2.9&amp;#160;million under
   their $75.0&amp;#160;million revolving loan facility. The revolving loan facility was terminated as of
   February&amp;#160;23, 2010. There was no balance outstanding at the date of termination.
