   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%"&gt;&lt;i&gt;Proposed Merger with Ventas&lt;/i&gt;
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent: 8%"&gt;On February&amp;#160;27, 2011, we entered into an Agreement and Plan of Merger (the &amp;#8220;Merger Agreement&amp;#8221;)
   with Ventas, Inc., a Delaware corporation, and Needles Acquisition LLC, a Delaware limited
   liability company and wholly owned subsidiary of Ventas (&amp;#8220;Merger Sub&amp;#8221;).
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent: 8%"&gt;Under the terms of the Merger Agreement, NHP will be merged with and into Merger Sub (the
   &amp;#8220;Merger&amp;#8221;), with Merger Sub surviving the Merger as a subsidiary of Ventas. Pursuant to the Merger
   Agreement, at the effective time of the Merger (the &amp;#8220;Effective Time&amp;#8221;), each outstanding share of
   common stock, other than shares held by any wholly owned subsidiary of NHP, by Ventas or by any
   subsidiary of Ventas, will be cancelled and converted into the right to receive 0.7866 shares (the
   &amp;#8220;Exchange Ratio&amp;#8221;) of common stock of Ventas (&amp;#8220;Ventas Common Stock&amp;#8221;).
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent: 8%"&gt;Upon completion of the Merger, (i)&amp;#160;each outstanding stock option will become fully vested and,
   in Ventas&amp;#8217;s discretion, either be (A)&amp;#160;cashed out based on the option spread or (B)&amp;#160;assumed by
   Ventas, on the same terms and conditions (subject to adjustment for the exchange ratio), provided
   that stock options granted to certain senior executives in February&amp;#160;2011 will be assumed by Ventas
   on the same terms and conditions (subject to adjustment for the Exchange Ratio); (ii)&amp;#160;each
   restricted stock unit will vest in full and be cashed out based on the Exchange Ratio, provided
   that (a)&amp;#160;restricted stock units granted to certain senior executives in February&amp;#160;2011 will be
   assumed by Ventas on the same terms and conditions (subject to adjustment for the Exchange Ratio)
   and (b)&amp;#160;certain restricted stock units granted to certain senior executives will vest and be
   settled in accordance with their terms; (iii)&amp;#160;each share of restricted stock will vest in full and
   be converted into Ventas Common Stock, based on the Exchange Ratio;
   (iv)&amp;#160;performance shares will vest under the relevant agreements and will be converted into
   Ventas Common Stock based on the Exchange Ratio; and (v)&amp;#160;dividend equivalent rights granted in
   connection with any award will become fully vested and be paid out.

   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent: 8%"&gt;We have made customary representations and warranties in the Merger Agreement and have agreed
   to customary covenants, including covenants regarding the operation of our business prior to the
   closing and covenants prohibiting us from soliciting, providing information or entering into
   discussions concerning proposals relating to alternative business combination transactions, except
   in limited circumstances relating to unsolicited proposals that constitute, or are reasonably
   expected to lead to, a superior proposal.
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent: 8%"&gt;Consummation of the Merger is subject to customary closing conditions, including approval of
   our stockholders and Ventas&amp;#8217;s stockholders. The Merger Agreement may be terminated under certain
   circumstances, including by either party if the Merger has not occurred by October&amp;#160;31, 2011, if an
   order is entered prohibiting or disapproving the transaction and the order has become final and
   non-appealable, if our stockholders or Ventas&amp;#8217;s stockholders fail to approve the transaction, or
   upon a material uncured breach by the other party that would cause the closing conditions not to be
   satisfied.

   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent: 8%"&gt;From time to time, we are a party to various legal proceedings, lawsuits and other claims (as
   to some of which we may not be insured) that arise in the normal course of our business. Regardless
   of their merits, these matters may require us to expend significant financial resources. Except as
   described herein and in our Annual Report on Form 10-K for the year ended December&amp;#160;31, 2010, we are
   not aware of any other legal proceedings or claims that we believe may have, individually or taken
   together, a material adverse effect on our business, results of operations or financial position.
   However, we are unable to predict the ultimate outcome of pending litigation and claims, and if our
   assessment of our liability with respect to these actions and claims is incorrect, such actions and
   claims could have a material adverse effect on our business, results of operations or financial
   position.
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%"&gt;Stockholder Litigation
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent: 8%"&gt;In the weeks following the announcement of the proposed Merger between us and Ventas on
   February&amp;#160;28, 2011, purported stockholders filed seven lawsuits against us and our directors. The
   purported stockholder plaintiffs commenced these actions in two jurisdictions: the Superior Court
   of the State of California, Orange County (the &amp;#8220;California State Court&amp;#8221;); and the Circuit Court for
   Baltimore City, Maryland (the &amp;#8220;Maryland State Court&amp;#8221;). All of these actions were brought as
   putative class actions, and two also purport to assert derivative claims on behalf of the company.
   All of these stockholder complaints allege that our directors breached certain alleged duties to
   our stockholders by approving the Merger Agreement, and certain complaints allege that we aided and
   abetted those breaches. All of the complaints request an injunction of the proposed Merger.
   Certain of the complaints also seek damages.
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent: 8%"&gt;In the California State Court, the following actions were filed purportedly on behalf of our
   stockholders: on February&amp;#160;28, 2011, a putative class action entitled &lt;i&gt;Palma v. Nationwide Health
   Properties, Inc., et al.&lt;/i&gt;; on March&amp;#160;3, 2011, a putative class action entitled &lt;i&gt;Barker v. Nationwide
   Health Properties, Inc., et al.&lt;/i&gt;; and on March&amp;#160;3, 2011, a putative class action entitled &lt;i&gt;Davis v.
   Nationwide Health Properties, Inc., et al.&lt;/i&gt;, which was subsequently amended on March&amp;#160;11, 2011 under
   the caption &lt;i&gt;Davids v. Nationwide Health Properties, Inc., et al&lt;/i&gt;. Each action names us and our
   directors as defendants. Each complaint alleges, among other things, that our directors breached
   certain alleged duties by approving the Merger Agreement because the proposed transaction
   purportedly fails to maximize stockholder value and purportedly provides the directors personal
   benefits not shared by our stockholders. The &lt;i&gt;Palma &lt;/i&gt;and &lt;i&gt;Davids &lt;/i&gt;actions allege that we aided and
   abetted those purported breaches. Along with other relief, the complaints seek an injunction
   against the closing of the proposed Merger. On March&amp;#160;22, 2011, the parties to the &lt;i&gt;Palma&lt;/i&gt;, &lt;i&gt;Barker&lt;/i&gt;,
   and &lt;i&gt;Davids &lt;/i&gt;actions signed a Stipulation and Proposed Order on Consolidation of Related Actions
   providing for consolidation of all three actions. On April&amp;#160;4, 2011, the defendants in all three
   actions demurred and moved to stay the proceedings in favor of parallel litigation pending in the
   Maryland State Court.

   Properties, Inc., et al.&lt;/i&gt;; on March&amp;#160;10, 2011, a putative class action entitled &lt;i&gt;Taylor v. Nationwide

   v. Pasquale, et al&lt;/i&gt;. All four actions name us and our directors as defendants. All four actions
   allege, among other things, that our directors breached certain alleged duties by approving the
   Merger Agreement because the proposed transaction purportedly fails to maximize stockholder value
   and purportedly provides certain directors personal benefits not shared by our stockholders. The
   &lt;i&gt;Haughey&lt;/i&gt;, &lt;i&gt;Rappaport &lt;/i&gt;and &lt;i&gt;Crowley &lt;/i&gt;actions allege that we aided and abetted those purported breaches.
   In addition to asserting direct claims on behalf of a putative class of our stockholders, the
   &lt;i&gt;Haughey &lt;/i&gt;and &lt;i&gt;Rappaport &lt;/i&gt;actions purport to bring derivative claims on behalf of the company,
   asserting breaches of certain alleged duties by our directors in connection with their approval of
   the proposed Merger. All four actions seek to enjoin the proposed Merger, and the &lt;i&gt;Taylor &lt;/i&gt;action
   seeks damages.
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent: 8%"&gt;On March&amp;#160;30, 2011, pursuant to stipulation of the parties, the Maryland State Court entered an
   order consolidating the &lt;i&gt;Crowley&lt;/i&gt;, &lt;i&gt;Taylor &lt;/i&gt;and &lt;i&gt;Haughey &lt;/i&gt;actions. On April&amp;#160;1, 2011, pursuant to
   stipulation of the parties, the Maryland State Court entered an order: (i)&amp;#160;certifying a class of
   our stockholders; and (ii)&amp;#160;providing for the plaintiffs to file a consolidated amended complaint.
   On April&amp;#160;13, 2011, the Maryland State Court held a status conference and thereafter entered certain
   scheduling orders. On April&amp;#160;22, 2011, the plaintiffs in Maryland filed a consolidated amended class
   action complaint.

   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent: 8%"&gt;As of March&amp;#160;31, 2011, we had entered into a joint venture to develop a medical office building
   (see Note 5) and entered into other agreements to develop two assisted and independent living
   facilities (see Note 3) and to fund the expansion of a skilled nursing facility securing a mortgage
   loan (see Note 4). As of March&amp;#160;31, 2011, we had committed to fund an additional $52.5&amp;#160;million under
   these agreements, of which $34.5&amp;#160;million will be funded through a third party construction loan
   obtained during the three months ended March&amp;#160;31, 2011 (see Note 10).

   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent: 8%"&gt;Under the terms of an agreement with PMB LLC, we agreed to extend to PMB LLC a $10.0&amp;#160;million
   line of credit to fund certain costs of PMB LLC with respect to the proposed development of
   multi-tenant medical office buildings. During the three months ended March&amp;#160;31, 2011, we funded $1.3
   million and received payments of $2.6&amp;#160;million under the line of credit. As of March&amp;#160;31, 2011, $3.6
   million was outstanding and is included in the caption &amp;#8220;Other assets&amp;#8221; on our consolidated balance
   sheet.
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent: 8%"&gt;During 2010, we agreed to loan two of our consolidated joint ventures up to $65.3&amp;#160;million as

   March&amp;#160;31, 2011.

   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent: 8%"&gt;We have entered into indemnification agreements with those partners who contributed
   appreciated property into NHP/PMB. Generally, under these indemnification agreements, if any of the
   appreciated real estate contributed by the partners is sold by NHP/PMB in a taxable transaction
   within a specified number of years after the property was contributed, we will reimburse the
   affected partners for the federal and state income taxes associated with the pre-contribution gain
