      On October 30, 2006, Accipiter Life Sciences Fund, LP ("Accipiter"),
together with the other participants, made a definitive filing with the
Securities and Exchange Commission ("SEC") of a proxy statement and accompanying
GOLD proxy card to be used to solicit votes for the election of its slate of
director nominees at the 2006 annual meeting of stockholders scheduled to be
held December 1, 2006 (the "2006 Annual Meeting") of Rural/Metro Corporation, a
Delaware corporation (the "Company").

Item 1: Accipiter issued the following press release on November 21, 2006:

PRESS RELEASE                           Source: Accipiter Life Sciences Fund, LP

ACCIPITER LIFE SCIENCES  CONTINUES TO URGE RURAL/METRO  SHAREHOLDERS TO VOTE FOR
ITS DIRECTOR NOMINEES
Tuesday November 21, 10:59 am ET

QUESTIONS WHETHER BOARD'S USE OF MISLEADING INFORMATION REGARDING ACCIPITER'S
OWNERSHIP IN A COMPETITOR IS A 'SMOKESCREEN' TO HIDE THE REAL ISSUES IN THE
PROXY CONTEST NEW YORK, Nov. 21 /PRNewswire/ -- Accipiter Life Sciences Fund, LP
today responded to the recommendations by Institutional Shareholder Services
(ISS) and Glass Lewis & Co. that Rural/Metro Corporation (Nasdaq: RURL)
shareholders vote for management's incumbent director nominees.

Gabe Hoffman, the managing member of the general partner of Accipiter, stated,
"While I am disappointed with the ultimate decisions of ISS and Glass Lewis not
to recommend the election of our director nominees to the Rural Board, I was
gratified to learn from the reports that we are not alone in questioning Rural's
'need for implementing numerous takeover defenses which generally are not in the
interests of all shareholders' and in recognizing that Rural 'substantially
underperformed the S&P Smallcap 600 Healthcare Services Index for the
twelve-month period ended September 5, 2006 (-25.5% versus -1.0%).'"

Mr. Hoffman continued: "We stand firm in our belief that Rural's shareholders
should vote in favor of Accipiter's nominees, both of whom are focused on
unlocking shareholder value by improving Rural's outdated corporate governance
practices, increasing financial transparency to shareholders through more
detailed reporting of operating results and through specific financial forecasts
and engaging an investment bank to explore all strategic alternatives available
to Rural. We reiterate that we do not have a premeditated agenda regarding which
specific strategic alternatives that Rural should pursue to unlock shareholder
value. As such, we strongly urge all Rural's shareholders to vote the GOLD proxy
card in favor of Accipiter's Board nominees so that we can enhance the value of
the Company's shares."

Accipiter also responded today to misleading and factually incorrect claims
repeatedly made by Rural regarding Accipiter's investment in a primary
competitor.

"Rural's false claims that Accipiter owns 10.1% of the outstanding shares of
Emergency Medical Services Corporation (EMS) and that such ownership poses a
conflict of interest have gone on now for too long and have been designed, in
our belief, to divert Rural shareholders' attention from the real issues at
hand," stated Mr. Hoffman. "We are once and for all setting the record straight.
Our investment in EMS since its IPO in December 2005 is consistent with our
belief that the emergency medical transportation segment is an attractive
long-term investment. Accipiter does not, however, own a 10% stake in EMS. In
fact, EMS publicly disclosed in its proxy statement that Accipiter's ownership
interest represented approximately 2.6% of its outstanding stock and less than
1% of the voting power of EMS. EMS filed its proxy statement in April 2006, more
than two months after the date of the public filing that Rural has continually
relied upon! Furthermore, Accipiter's Form 13F filing for the period ended
September 30, 2006 reports that Accipiter owns 860,768 shares of EMS, or
approximately 2.02% of EMS's outstanding shares. We do not understand how Rural
could continue to make such a mistake. Moreover, Rural's inference that
Accipiter's director nominees would not carry out their duties in an ethical,
legal and professional manner is baseless and uncalled for."




Accipiter Life Sciences urges all shareholders to vote for Gabe Hoffman and
Nicole Viglucci as soon as possible by signing and mailing in their GOLD proxy
card and discarding the WHITE proxy card mailed by the current Board of Rural.
