      Re:   NOTICE OF NOMINATION FOR ELECTION AS DIRECTORS AT THE 2007 ANNUAL

Dear Sir or Madam:

      On  September  19,  2007,   Rural/Metro   Corporation  ("Rural")  publicly
announced for the first time that it had  scheduled  its 2007 annual  meeting of
stockholders for 3 p.m. on Thursday,  February 28, 2008. This letter shall serve
to satisfy the advance  notice  requirements  of Article II, Section 2.04 of the
Second Amended and Restated  Bylaws (the "Bylaws") of Rural as to the nomination
by Accipiter Life Sciences Fund, LP, a Delaware limited partnership  ("Accipiter
Life Sciences"), of three (3) nominees for election to the Board of Directors of
Rural (the "Rural Board") at the 2007 annual meeting of  stockholders  of Rural,
or any other meeting of stockholders held in lieu thereof, and any adjournments,
postponements,   reschedulings  or  continuations   thereof  (the  "2007  Annual
Meeting").  This  letter  supersedes  the letter to you dated  August  30,  2007
notifying Rural of Accipiter Life Sciences' nomination of directors for election
at the 2007 Annual Meeting.

      This letter, and all Exhibits attached hereto are collectively referred to
as the  "Notice."  Accipiter  Life Sciences is the  beneficial  owner of 745,595
shares of common stock, $.01 par value per share (the "Common Stock"), of Rural,
1,000 shares of which are held of record by Accipiter Life  Sciences.  Accipiter
Life Sciences Fund II, LP, a Delaware limited partnership ("ALSF II"), Accipiter
Life Sciences Fund (Offshore), Ltd., a Cayman Islands company ("ALSF Offshore"),
Accipiter  Life  Sciences Fund II  (Offshore),  Ltd., a Cayman  Islands  company
("ALSF II  Offshore"),  Accipiter  Life  Sciences  Fund II (QP),  LP, a Delaware
limited  partnership  ("ALSF  II QP"),  Accipiter  Capital  Management,  LLC,  a
Delaware limited  liability  company  ("Management"),  Candens  Capital,  LLC, a
Delaware limited liability company ("Candens") and Gabe Hoffman,  are affiliates
of  Accipiter  Life  Sciences  (together  with  Accipiter  Life  Sciences,   the
"Accipiter Group"). ALSF II, ALSF Offshore,  ALSF II Offshore and ALSF II QP are
the beneficial  owners of 534,951 shares,  749,867 shares,  1,059,333 shares and
611,901 shares of Common Stock, respectively.  As the general partner of each of
Accipiter  Life  Sciences,  ALSF II and ALSF II QP,  Candens  may be  deemed  to
beneficially  own the  1,892,447  shares  collectively  owned by Accipiter  Life
Sciences,  ALSF II and ALSF II QP.  As the  investment  manager  of each of ALSF
Offshore and ALSF II Offshore,  Management may be deemed to beneficially own the

Life Sciences hereby nominates and notifies you of its intent to nominate Eugene
Davis,  Mohsin Y. Meghji and Earl P. Holland as nominees (the  "Nominees") to be
elected to the Rural Board at the 2007 Annual  Meeting.  Accipiter Life Sciences
believes that the terms of three (3) Class I directors  currently serving on the
Rural Board expire at the 2007 Annual Meeting. To the extent there are in excess
of three (3)  vacancies  on the Rural Board to be filled by election at the 2007
Annual Meeting or Rural increases the size of the Rural Board above its existing
size, Accipiter Life Sciences reserves the right to nominate additional nominees
to be  elected  to the  Rural  Board  at the  2007  Annual  Meeting.  Additional
nominations made pursuant to the preceding sentence are without prejudice to the
position of Accipiter Life Sciences that any attempt to increase the size of the
current Rural Board or to  reconstitute  or reconfigure the classes on which the
current  directors  serve  constitutes  an  unlawful   manipulation  of  Rural's
corporate machinery. If this Notice shall be deemed for any reason by a court of
competent  jurisdiction to be ineffective with respect to any individual Nominee
at the 2007 Annual  Meeting,  or if any  individual  Nominee  shall be unable to
serve for any reason, this Notice shall continue to be effective with respect to
the  remaining  Nominee(s)  and as to any  replacement  Nominee(s)  selected  by
Accipiter Life Sciences.
