Explanatory Note: This Amendment No. 4 (this “Amendment”) amends and supplements the Schedule 13D (the “Initial 13D”) filed with the U.S. Securities and Exchange Commission (the “Commission”) on April 1, 2008 relating to shares of common stock, par value $0.01 per share (the “Common Stock”) of Rural/Metro Corporation (the “Issuer”) as amended and supplemented by Amendment No. 1 to the Initial 13D filed on February 3, 2009, Amendment No. 2 to the Initial 13D filed on November 25, 2009, and Amendment No. 3 to the Initial 13D filed on May 21, 2010.

As used in this statement, the term “Filers” collectively refers to:

• Coliseum Capital Management, LLC, a Delaware limited liability company (“CCM”);

• Coliseum Capital, LLC, a Delaware limited liability company (“CC”);

• Coliseum Capital Partners, L.P., a Delaware limited partnership (“CCP”);

• Blackwell Partners, LLC, a Georgia limited liability company (“Blackwell”):

• Adam Gray (“Gray”); and

• Christopher Shackelton (“Shackelton”).

Item 4. Purpose of Transaction.

Item 4 is amended and restated in its entirety as follows:

On March 28, 2011, the Issuer 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”). Merger Sub and Parent are affiliates of Warburg Pincus LLC (“Warburg”) formed by Warburg in order to acquire the Company.

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. In the Merger, each outstanding share of common stock of the Company, other than any shares owned by the Company, Parent, Merger Sub or any other direct or indirect wholly owned subsidiary of the Company or of Parent or any shareholders who are entitled to and who properly exercise appraisal rights under Delaware law, will be cancelled and converted into the right to receive $17.25 in cash, without interest.

The Company’s Board of Directors, acting on the recommendation of a Special Committee consisting entirely of independent directors, unanimously approved the terms of the Merger Agreement and has resolved to recommend adoption of the Merger Agreement by Company shareholders. In addition to shareholder approval, the transaction is subject to the satisfaction of customary closing conditions and regulatory approvals. Closing is not subject to any financing condition.

The Merger Agreement is filed as Exhibit 1 to this Amendment and any references to or descriptions of the Merger and the Merger Agreement are qualified in their entirety by reference to the full text of the Merger Agreement, which is incorporated by reference herein in its entirety.

In addition, as an inducement for Parent to enter into the Merger Agreement, CCP and Blackwell (collectively, the “Stockholders”) entered into a voting agreement dated as of March 28, 2011. For a description of the voting agreement, see Item 6 below, which description is incorporated herein by reference in response to this Item 4. The Voting Agreement is filed as Exhibit 2 to this Amendment.

Item 5. Interest in Securities of the Issuer.

Item 5 is amended and restated in its entirety as follows:

Page 8 of 11

CUSIP No. 781748108 

(a) and (b) The information relating to the beneficial ownership of Common Stock by each of the Filers set forth in Rows 7 through 13 of the cover pages hereto is incorporated herein by reference. The percentages set forth in Row 13 for all cover pages filed herewith are calculated based upon 25,380,542 shares of Common Stock issued and outstanding as of March 24, 2011, as disclosed by the Issuer to the Filers.

The number of shares of Common Stock beneficially owned by CCP includes 11,766 restricted stock units (RSUs) that will vest and be cashed out upon consummation of the Merger.

CCM is an investment adviser whose clients, including CCP and Blackwell, have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the Common Stock. CC is the general partner of CCP. Gray and Shackelton are the managers of CC and CCM.

(c) There has been no change in the number of shares of Common Stock beneficially owned by the Filers in the past 60 days.

(d) Not applicable.

(e) Not applicable.

Item 6. Contracts, Arrangement, Understandings or Relationships with Respect to Securities of the Issuer.

Item 6 is amended and supplemented as follows:

Concurrent with the execution and delivery of the Merger Agreement, the Stockholders (as defined in Item 4) entered into a Voting Agreement with Parent (the “Voting Agreement”). Shares of Common Stock beneficially owned by the Stockholders subject to the Voting Agreement (the “Voting Agreement Shares”) constituted approximately 12.4% of the total issued and outstanding shares of Common Stock as of March 24, 2011. Any options, warrants and other rights to purchase shares of the Common Stock or other voting capital stock or securities of the Issuer and any other securities convertible into or exercisable or exchangeable for shares of Common Stock or other voting capital stock or securities of the Issuer acquired by the Stockholders after March 28, 2011 will also be subject to the Voting Agreement. Pursuant to the Voting Agreement, among other things, Stockholders agreed to (i) vote their shares in favor of the adoption of the Merger Agreement and against any takeover bid by a third party and (ii) comply with certain restrictions on the disposition of such shares, subject to the terms and conditions contained therein.

The Stockholders have granted Parent an irrevocable proxy to vote their shares of Common Stock. The irrevocable proxy will allow Parent to vote the Voting Agreement Shares as specified above. The Voting Agreement will terminate on the earlier of (i) the effective time of the Merger and (ii) the date of termination of the Merger Agreement in accordance with its terms.

The Voting Agreement is filed as Exhibit 2 to this Amendment and any references to or descriptions of the Voting Agreement are qualified in their entirety by reference to the full text of the Voting Agreement, which is incorporated by reference herein in its entirety.
