      Accipiter  Life Sciences  Fund,  LP ("ALS Fund"),  together with the other
participants  named herein,  is filing materials  contained in this Schedule 14A
with the  Securities  and Exchange  Commission  ("SEC") in  connection  with the
solicitation of proxies for the election of a slate of director  nominees at the
2007 annual  meeting of  stockholders  (the  "Annual  Meeting")  of  Rural/Metro
Corporation,  a Delaware corporation (the "Company"). ALS Fund has not yet filed
a proxy statement with the SEC with regard to the Annual Meeting

Item 1: On September  11, 2007,  Accipiter  Capital  Management,  LLC issued the
following press release:

NEWS RELEASE

FOR IMMEDIATE RELEASE

  ACCIPITER CAPITAL MANAGEMENT EXPRESSES CONCERN OVER RURAL/METRO'S FAILURE TO
          RELEASE FOURTH QUARTER AND FISCAL YEAR END FINANCIAL RESULTS

      NEW YORK,  NEW YORK,  SEPTEMBER  11, 2007 - Accipiter  Capital  Management
expressed its concern today over Rural/Metro  Corporation's  (Nasdaq: RURL) lack
of communication  with  stockholders  regarding the Company's fourth quarter and
fiscal year end financial results.

      Gabe Hoffman,  Managing  Member of Accipiter  Capital  Management,  stated
"Accipter,  a long-term,  major stockholder owning nearly 15% of the outstanding
shares of Rural,  is concerned  with the Company's  lack of  communication  with
stockholders  regarding  its  release  of fourth  quarter  and  fiscal  year end
financial  numbers.  At the end of July, Rural issued a press release trumpeting
the success of its short-term internal  initiatives and indicating its intent to
hold a  management-hosted  conference call to discuss Rural's fourth quarter and
fiscal  year end  results.  However,  it is now less  than two days from the SEC
filing deadline,  and stockholders have been treated to nothing but silence, not
even call-in  details for  management's  conference  call.  We demand that Rural
promptly  inform  stockholders  of its plans to report fourth quarter and fiscal
year end results,  as well as inform stockholders of any potential plans to file
for an extension on its 10-K filing"
