Item 1.01. Entry into a Material Definitive Agreement.

Public Storage Properties IV, Ltd., a California limited partnership (the “Partnership”), has entered into an Agreement and Plan of Reorganization by and among, inter alia, Public Storage, the Partnership and Public Storage Properties Merger Co. (“Merger Sub”), dated as of June 30, 2011 (the “Agreement and Plan of Reorganization”).  Upon consummation of the transactions contemplated by the Agreement and Plan of Reorganization, Merger Sub will merge with and into the Partnership and limited partners (other than Public Storage and its consolidated affiliates) holding each of the Partnership’s outstanding units will have their units converted into the right to receive approximately $50.0 million in value of Public Storage common shares or, at the limited partner’s election, in cash, and thereafter the Partnership will be dissolved. The Public Storage affiliates, including the Hughes family and their affiliates, have indicated that they intend to elect cash so that the Public Storage common shares issued in the merger will not exceed a value of approximately $31.8 million.

The merger and the Agreement and Plan of Reorganization have been approved by limited partners, including Public Storage and B. Wayne Hughes and members of his family, holding the requisite percentage of outstanding units.  Accordingly, no proxies are being solicited and other limited partners are not being asked to vote on the proposed merger. The merger is conditioned on, among other things, the effectiveness of a registration statement to be filed by Public Storage under the Securities Act and certain other customary closing conditions. Availability of financing for the merger is not a condition to the parties’ obligations to close.

The foregoing description of the Agreement and Plan of Reorganization is only a summary, does not purport to be complete and is qualified in its entirety by reference to the full text of the Agreement and Plan of Reorganization, which is filed as Exhibit 2.1 hereto, and is incorporated herein by reference.

Robert A. Stanger & Co. (“Stanger”) serves as the financial advisor to the Partnership. On June 30, 2011, Stanger delivered a written opinion to the board of trustees of Public Storage, which is a general partner of the Partnership, to the effect that, as of the date of the opinion and subject to the limitations contained therein, from a financial point of view, the consideration to be offered to the holders of the units (other than Public Storage and the family of B. Wayne Hughes) is fair to such holders.

The Agreement and Plan of Reorganization has been attached as an exhibit to provide investors and security holders with information regarding its terms. It is not intended to provide any other factual information about the parties or any of their respective affiliates or businesses. The representations, warranties and covenants contained in the Agreement and Plan of Reorganization were made only for the purposes of such agreement and as of specified dates, were solely for the benefit of the parties to such agreement, and may be subject to limitations agreed upon by the contracting parties. The representations and warranties may have been made for the purposes of allocating contractual risk between the parties to the Agreement and Plan of Reorganization instead of establishing these matters as facts, and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors.

Investors and security holders are not third-party beneficiaries under the Agreement and Plan of Reorganization and should not rely on the representations, warranties and covenants or any descriptions thereof as characterizations of the actual state of facts or condition of the parties or any of their respective affiliates or businesses. Moreover, the assertions embodied in the representations and warranties contained in the Agreement and Plan of Reorganization are qualified by information in a disclosure schedule that the parties have exchanged. Accordingly, investors and security holders should not rely on the representations and warranties as characterizations of the actual state of facts of the parties or any of their respective affiliates or businesses. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the Agreement and Plan of Reorganization, which subsequent information may or may not be fully reflected in the Partnership’s public disclosures.

Important Additional Information will be Filed with the SEC:

In connection with the proposed transaction, Public Storage filed a registration statement with the SEC. INVESTORS AND SECURITY HOLDERS ARE URGED TO READ THE REGISTRATION STATEMENT FILED ON JULY 1, 2011 AND ANY OTHER RELEVANT DOCUMENTS TO BE FILED WITH THE SEC IN CONNECTION WITH THE PROPOSED TRANSACTION BECAUSE THEY WILL CONTAIN IMPORTANT INFORMATION ABOUT PUBLIC STORAGE, THE PROPOSED TRANSACTION AND RELATED MATTERS. The final prospectus statement will be mailed to the Partnership’s limited partners.

Investors and security holders will be able to obtain free copies of these documents when they become available through the website maintained by the SEC at www.sec.gov. In addition, the documents filed with the SEC may be obtained free of charge by directing such requests to Investor Services, Public Storage, 701 Western Ave., Glendale, California 91201-2349; telephone 818-244-8080.
