Item 8.01.        Other Events.

As previously disclosed, on March 28, 2011, Rural/Metro Corporation, a Delaware corporation (the “Company”) entered into an Agreement and Plan of Merger (the “Merger Agreement”) with WP Rocket Holdings LLC, a Delaware limited liability company (“Parent”), and WP Rocket Merger Sub, Inc., a Delaware corporation and a wholly-owned subsidiary of Parent (“Merger Sub”). The Merger Agreement provides for the merger of Merger Sub with and into the Company (the “Merger”), with the Company surviving the Merger as a wholly-owned subsidiary of Parent. On May 26, 2011, the Company filed a definitive proxy statement describing the Merger with the U.S. Securities and Exchange Commission (the “SEC”). Merger Sub and Parent are affiliates of Warburg Pincus LLC (“Warburg Pincus”) formed by Warburg Pincus to acquire the Company.

As disclosed in the Company’s definitive proxy statement, the Company, each member of the Board of Directors of the Company (the “Board of Directors”), Warburg Pincus, Parent and Merger Sub were named as defendants in purported class action lawsuits brought by alleged stockholders of the Company challenging the Merger.  The stockholder actions were filed in the Court of Chancery of the State of Delaware (Llorens v. Rural/Metro Corporation, et al., filed April 6, 2011 and amended April 21, 2011, (the “Llorens action”) and Joanna Jervis v. Rural/Metro Corporation, et al., filed May 16, 2011, (the “Jervis Delaware action”)) and in the Superior Court of the State of Arizona, County of Maricopa (Joanna Jervis v. Rural/Metro Corporation, et al., filed April 6, 2011 and amended April 14, 2011 (the “Jervis Arizona action”)).

On May 16, 2011, Joanna Jervis, the stockholder in the Jervis Arizona action, filed a complaint in the Court of Chancery of the State of Delaware. On May 23, 2011, after plaintiff filed a complaint in Delaware, the parties filed a stipulation of dismissal and proposed order dismissing the Jervis Arizona action, which the court so-ordered on May 24, 2011.

On May 27, 2011, the Court of Chancery of the State of Delaware entered an Order of Consolidation and Appointment of Lead Counsel designating Plaintiff Llorens as Lead Plaintiff and Faruqi & Faruqi, LLP as Lead Counsel under the caption In re Rural Metro Corporation Consolidated Shareholders Litigation, C.A. No. 6350-VCS (the “Consolidated Delaware Action”).  A Second Scheduling Order was entered on June 10, 2011, updating the Stipulated Scheduling Order entered on May 3, 2011.  Depositions were completed on June 10, 2011.

On June 16, 2011, the Company, each member of the Board of Directors, Warburg Pincus, Parent, Merger Sub and the Lead Plaintiff in the Consolidated Delaware Action reached an agreement in principle, subject to the Court’s approval, providing for the settlement and dismissal, with prejudice, of the Consolidated Delaware Action filed in connection with the Merger. Pursuant to such agreement in principle, on June 16, 2011, the Company agreed to make certain supplemental disclosures regarding the Merger and filed a supplement to the Company’s definitive proxy statement (the “supplement”).

The settlement will not affect the merger consideration to be paid to stockholders of the Company in connection with the proposed merger or the timing of the special meeting of stockholders of the Company scheduled for June 27, 2011 at 10:00 a.m., local time, at the Company’s corporate headquarters at 9221 East Via de Ventura, Scottsdale, Arizona 85258 to consider and to vote upon a proposal to adopt the merger agreement, among other things.
