   &lt;div align="left" style="font-size: 10pt; margin-top: 12pt"&gt;&lt;b&gt;1. Recent Developments&lt;/b&gt;
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;On May&amp;#160;16, 2010, we entered into an Agreement and Plan of Merger (the &amp;#8220;Merger Agreement&amp;#8221;) with
   Universal Health Services, Inc., a Delaware corporation (&amp;#8220;UHS&amp;#8221;), and Olympus Acquisition Corp., a
   Delaware corporation and a wholly-owned subsidiary of UHS (&amp;#8220;Merger Sub&amp;#8221;). Under the terms of the
   Merger Agreement, Merger Sub will be merged with and into us, with us continuing as the surviving
   corporation and as a wholly-owned subsidiary of UHS (the &amp;#8220;Merger&amp;#8221;). On October&amp;#160;5, 2010, our
   stockholders adopted the Merger Agreement at a special meeting of stockholders.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;At the effective time of the Merger, each outstanding share of our common stock (the &amp;#8220;Common
   Stock&amp;#8221;), other than shares held in our treasury or owned by UHS or Merger Sub, will be cancelled and converted into the right to receive $33.75 in cash, without interest (the
   &amp;#8220;Merger Consideration&amp;#8221;), or an aggregate of approximately $2.0&amp;#160;billion. Including the assumption of
   approximately $1.1&amp;#160;billion in net debt, the total transaction consideration is approximately $3.1
   billion.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;We made customary representations, warranties and covenants in the Merger Agreement. We are subject
   to a &amp;#8220;no-shop&amp;#8221; restriction on our ability to solicit third-party proposals, provide information and
   engage in discussions with third parties.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;The Merger Agreement contains termination rights and provides that, upon the
   termination of the Merger Agreement, under specified circumstances, we will be required to
   reimburse UHS for its transaction expenses and that, under specified circumstances, we will be
   required to pay UHS a termination fee of $71.5&amp;#160;million.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;The parties to the Merger Agreement are entitled to specific performance of the terms and
   provisions of the Merger Agreement, in addition to any other remedy to which they are entitled,
   including damages for any breach of the Merger Agreement by the other party. Consummation of the
   Merger is not subject to a financing condition, but is subject to various other conditions,
   including expiration or termination of applicable waiting periods under the Hart-Scott-Rodino
   Antitrust Improvements Act of 1976 (&amp;#8220;HSR Act&amp;#8221;) and other customary closing conditions. On July&amp;#160;28,
   2010, we and UHS each received a Request for Additional Information (&amp;#8220;Second Request&amp;#8221;) from the
   Federal Trade Commission (&amp;#8220;FTC&amp;#8221;) in connection with their filings under the HSR Act. Both we and UHS have complied with the Second Request and anticipate FTC approval of the transaction in November 2010. The parties also expect to close
   the transaction in November 2010. Where this Quarterly Report on Form 10-Q
   discusses our future plans, strategies or activities, such discussion does not give effect to the
   proposed Merger.
   &lt;/div&gt;
