                           Re: RURAL/METRO CORPORATION

Dear Mr. Meghji:

      Thank you for  agreeing to serve as a nominee for election to the Board of
Directors of  Rural/Metro  Corporation  ("Rural") in  connection  with the proxy
solicitation  that  Accipiter  Life  Sciences  Fund,  LP  ("Accipiter")  and its
affiliates are considering undertaking to elect directors at Rural's 2007 Annual
Meeting  of  Stockholders,  or any other  meeting of  stockholders  held in lieu
thereof,  and any  adjournments,  postponements,  reschedulings or continuations
thereof (the "Accipiter  Solicitation").  Your  outstanding  qualifications,  we
believe, will prove a valuable asset to Rural and all of its stockholders.  This
letter will set forth the terms of our agreement.

      Accipiter agrees to jointly and severally  indemnify and hold you harmless
against any and all claims of any nature,  whenever  brought,  arising  from the
Accipiter  Solicitation  and  any  related  transactions,  irrespective  of  the
outcome; PROVIDED, however, that you will not be entitled to indemnification for
claims arising from your own criminal actions, fraud,  negligence,  bad faith or
willful misconduct;  PROVIDED FURTHER,  that this indemnification  agreement and
all of the Accipiter's  obligations hereunder shall terminate upon your becoming
a director of Rural.  This  indemnification  will  include any and all (each,  a
"Loss")  losses,   liabilities,   damages,   demands,  claims,  suits,  actions,
judgments,  or causes of action,  assessments,  costs and  expenses,  including,
without limitation, interest, penalties, reasonable attorneys' fees, and any and
all  reasonable  costs and  expenses  incurred in  investigating,  preparing  or
defending against any litigation,  commenced or threatened, any civil, criminal,
administrative or arbitration  action, or any claim whatsoever,  and any and all
amounts  paid  in  settlement  of any  claim  or  litigation  asserted  against,
resulting, imposed upon, or incurred or suffered by you, directly or indirectly,
as a result  of or  arising  from the  Accipiter  Solicitation  and any  related
transactions.

      In the event of a claim against you pursuant to the prior paragraph or the
occurrence of a Loss, you shall give  Accipiter  written notice of such claim or
Loss. Upon receipt of such written  notice,  the Accipiter will provide you with
counsel to represent you. Such counsel shall be reasonably acceptable to you. In
addition,  you will be reimbursed promptly for all Losses suffered by you and as
incurred as provided herein. Accipiter may not enter into any settlement of loss
or claim without your consent unless such  settlement  includes a release of you
from any and all  liability  in respect  of such  claim.  Accipiter  will not be
responsible for fees, costs or expenses of separate counsel retained by you. You
may not enter into any  settlement of loss or claim without the written  consent
of Accipiter, which consent will not be unreasonably withheld.
