   &lt;div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%"&gt;As of June&amp;#160;30, 2010, approximately 38.9%, 21.5% and 14.1% of our properties, based on the
   gross book value of real estate investments (including assets held for sale), were managed or
   operated by Sunrise, Brookdale Senior Living (whose subsidiaries include Brookdale Living
   Communities, Inc. (&amp;#8220;Brookdale&amp;#8221;) and Alterra Healthcare Corporation (&amp;#8220;Alterra&amp;#8221;)) and Kindred,
   respectively. Seniors housing communities and skilled nursing facilities constituted approximately
   73.9% and 12.6%, respectively, of our portfolio, based on the gross book value of real estate
   investments (including assets held for sale), as of June&amp;#160;30, 2010, with the remaining properties
   consisting of hospitals, MOBs and other healthcare assets. As of June&amp;#160;30, 2010, our properties
   were located in 43 states and two Canadian provinces, with properties in two states each accounting
   for 10% or more of total revenues during the six months then ended.

   &lt;div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%"&gt;Approximately 25.2% and 26.8% of our total revenues and 37.0% and 38.8% of our total net
   operating income (&amp;#8220;NOI,&amp;#8221; which is defined as total revenues, less interest and other income and
   property-level operating expenses) (including amounts in discontinued operations) for the six
   months ended June&amp;#160;30, 2010 and 2009, respectively, were derived from our four Kindred Master
   Leases. Approximately 12.5% and 13.0% of our total revenues and 18.3% and 19.2% of our total NOI
   (including amounts in discontinued operations) for the six months ended June&amp;#160;30, 2010 and 2009,
   respectively, were derived from our lease agreements with Brookdale Senior Living. Each of the
   Kindred Master Leases and our leases with Brookdale Senior Living is a triple-net lease pursuant to
   which the tenant is required to pay all insurance, taxes, utilities and maintenance and repairs
   related to the properties. In addition, the tenants are required to comply with the terms of the
   mortgage financing documents, if any, affecting the properties.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%"&gt;In view of the fact that Kindred and Brookdale Senior Living lease a substantial portion of
   our triple-net leased properties and are each a significant source of our revenues and operating
   income, their financial condition and ability and willingness to satisfy their obligations under
   their respective leases and other agreements with us, as well as their willingness to renew those
   leases upon expiration of the terms thereof, have a considerable impact on our results of
   operations and our ability to service our indebtedness and to make distributions to our
   stockholders. We cannot assure you that Kindred or Brookdale Senior Living will have sufficient
   assets, income and access to financing to enable it to satisfy its obligations under its respective
   leases and other agreements with us, and any inability or unwillingness on its part to do so would
   have a material adverse effect on our business, financial condition, results of operations and
   liquidity, our ability to service our indebtedness and our ability to make distributions to our
   stockholders, as required for us to continue to qualify as a REIT (a &amp;#8220;Material Adverse Effect&amp;#8221;). We
   also cannot assure you that Kindred or Brookdale Senior Living will elect to renew its respective
   leases with us upon expiration of the initial base terms or any renewal terms thereof.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%"&gt;We are party to long-term management agreements with Sunrise pursuant to which Sunrise
   currently provides comprehensive accounting and property management services with respect to 79 of
   our seniors housing communities. Each management agreement has a term of 30&amp;#160;years from its
   effective date, the earliest of which began in 2004. Approximately 44.7% and 44.2% of our total
   revenues and 22.1% and 20.3% of our total earnings before interest, taxes, depreciation and
   amortization (including non-cash stock-based compensation), excluding merger-related expenses and
   deal costs and gains and losses on real estate disposals (&amp;#8220;Adjusted EBITDA&amp;#8221;) (including amounts in
   discontinued operations) for the six months ended June&amp;#160;30, 2010 and 2009, respectively, were
   attributable to senior living operations managed by Sunrise.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%"&gt;Unlike Kindred and Brookdale Senior Living, Sunrise does not lease properties from us, but
   rather acts as a property manager for all of our senior living operations. Therefore, while we are
   not directly exposed to credit risk with Sunrise, Sunrise&amp;#8217;s inability to efficiently and
   effectively manage our properties and to provide timely and accurate accounting information with
   respect thereto could have a Material Adverse Effect on us. Although we have various rights as
   owner under the Sunrise management agreements, we rely on Sunrise&amp;#8217;s personnel, good faith,
   expertise, historical performance, technical resources and information systems, proprietary
   information and judgment to manage our seniors housing communities efficiently and effectively. We
   also rely on Sunrise to set resident fees and otherwise operate those properties pursuant to our
   management agreements. Any adverse developments in Sunrise&amp;#8217;s business and affairs or financial
   condition, including without limitation, the acceleration of its indebtedness, the inability to
   renew or extend its revolving credit facility, the enforcement of default remedies by its
   counterparties, or the commencement of insolvency proceedings under the U.S. Bankruptcy Code by or
   against Sunrise could have a Material Adverse Effect on us.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%"&gt;Each of Kindred, Brookdale Senior Living and Sunrise is subject to the reporting requirements
   of the SEC and is required to file with the SEC annual reports containing audited financial
   information and quarterly reports containing unaudited financial information. The information
   related to Kindred, Brookdale Senior Living and Sunrise contained or referred to in this Quarterly
   Report on Form 10-Q is derived from filings made by Kindred, Brookdale Senior Living or Sunrise, as
   the case may be, with the SEC or other publicly available information, or has been provided to us
   by Kindred, Brookdale Senior Living or Sunrise. We have not verified this information either
   through an independent investigation or by reviewing Kindred&amp;#8217;s, Brookdale Senior Living&amp;#8217;s or
   Sunrise&amp;#8217;s public filings. We have no reason to believe that this information is inaccurate in any
   material respect, but we cannot assure you that all of this information is accurate. Kindred&amp;#8217;s,
   Brookdale Senior Living&amp;#8217;s and Sunrise&amp;#8217;s filings with the SEC can be found at the SEC&amp;#8217;s website at
   www.sec.gov. We are providing this data for informational purposes only, and you are encouraged to
   obtain Kindred&amp;#8217;s, Brookdale Senior Living&amp;#8217;s and Sunrise&amp;#8217;s publicly available filings from the SEC.

      <ElementDefenition>Description of any concentrations existing at the date of the financial statements that make an entity vulnerable to a reasonably possible, near-term, severe impact. The entity should inform financial statement users about the general nature of the risk associated with the concentration, and may indicate the percentage of concentration risk as of the balance sheet date. Disclosure of any financial instrument credit risk concentration also should indicate the maximum amount of loss that would be incurred upon complete failure of the counterparty to perform and the entity's collateral policies or other policies that limit the loss exposure.
