EXPLANATORY NOTE

Rural/Metro Corporation has prepared Amendment No. 1 for the purpose of
filing with the Securities and Exchange Commission Exhibits 4.5 and 5 to the
Registration Statement. Amendment No. 1 does not modify any provision of the
Prospectus included in the Registration Statement; accordingly, such Prospectus
has not been included herein.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS

The Company's amended and restated Bylaws require the Company to indemnify
its directors, officers, employees and agents to the fullest extent permitted by
the Delaware General Corporation Law, including those circumstances in which
indemnification would otherwise be discretionary, except that the Company will
not be obligated to indemnify any such person (i) with respect to proceedings,
claims or actions initiated or brought voluntarily by any such person and not by
way of defense; (ii) for any amounts paid in settlement of an action indemnified
against by the Company without the proper written consent of the Company; or
(iii) in connection with any event in which the person did not act in good faith
and in a manner reasonably believed to be in, or not opposed to, the best
interests of the Company. In addition, the Company has entered or will enter
into Indemnity Agreements with each of its directors and officers providing for
indemnification of and advancement of expenses to the directors and officers to
the fullest extent permitted by law except (a) if and to the extent that payment
is made to the indemnitee under an insurance policy or otherwise; (b) if and to
the extent that a claim is decided adversely based on or attributable to the
indemnitee gaining any personal profit or advantage to which the indemnitee was
not legally entitled; (c) if and to the extent that the indemnifiable event
constituted or arose out of the indemnitee's willful misconduct or gross
negligence; or (d) if and to the extent that the proceeding is initiated by the
indemnitee against the Company of any of its officers or directors, unless the
Company has consented to or joined in the initiation of the proceeding. The
Delaware General Corporation Law contains an extensive indemnification provision
that permits a corporation to indemnify any person who is or was a party or is
threatened to be made a party to any threatened, pending or completed action,
suit or proceeding, whether civil, criminal, administrative or investigative, by
reason of the fact that he or she is or was a director, officer, employee or
agent of the corporation, or is or was serving at the request of the corporation
as a director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise, against expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by him or her in connection with such action, suit or proceeding if he
or she acted in good faith and in a manner he or she reasonably believed to be
in or not opposed to the best interests of the corporation, and, with respect to
any criminal action or proceeding, had no reasonable cause to believe his or her
conduct was unlawful.

The Company's Second Restated Certificate eliminates the personal liability
of the directors of the Company to the Company or its stockholders for monetary
damages for breach of their duty of care except to the extent that such
exemption from liability or limitation thereof is not permitted under the
Delaware General Corporation Law. The Delaware General Corporation Law prohibits
a corporation from eliminating or limiting the liability of a director (i) for
any breach of the director's duty of loyalty to the corporation or its
stockholders; (ii) for acts or omissions not in good faith or that involve
intentional misconduct or a knowing violation of law; (iii) for liability under
Section 174 of the Delaware General Corporation Law (relating to certain
unlawful dividends, stock purchases or stock redemptions); or (iv) for any
transaction from which the director derived any improper personal benefit.

(1) Incorporated by reference to the Registration Statement on Form S-1 of the
Registrant (Registration No. 33-63448) filed May 27, 1993 and declared
effective July 15, 1993.

(b) Financial Statement Schedules

Schedule II Valuation and Qualifying Accounts incorporated by reference to
the Registrant's Annual Report on Form 10-K for the fiscal year ended June 30,
1997.

All other schedules have been omitted on the basis of immateriality or
because such schedules are not otherwise applicable.

ITEM 22. UNDERTAKINGS

(a) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of
1934) that is incorporated by reference in the registration statement shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

(b) (1) The undersigned registrant hereby undertakes as follows: that prior
to any public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this registration statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
issuer undertakes that such reoffering prospectus will contain the information
called for by the applicable registration form with respect to reofferings by
persons who may be deemed underwriters, in addition to the information called
for by the other items of the applicable form.

(2) The registrant undertakes that every prospectus: (i) that is filed
pursuant to paragraph (1) immediately preceding, or (ii) that purports to meet
the requirements of Section 10(a)(3) of the Act and is used in connection with
an offering of securities subject to Rule 415, will be filed as a part of an
amendment to the registration statement and will not be used until such
amendment is effective, and that, for purposes of determining any liability
under the Securities Act of 1933, each such post-effective amendment shall be

II-2
8

deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

(c) Insofar as indemnification for liabilities arising under the Act may be
permitted to directors, officers and controlling persons of the registrant
pursuant to the foregoing provisions, or otherwise, the registrant has been
advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant, in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question of whether such indemnification by it is against
public policy as expressed in the Act and will be governed by the final
adjudication of such issue.

(d) The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Item 4, 10(b), 11, or 13 of this Form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.

(e) The undersigned registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction that was not
the subject of and included in the registration statement when it became
effective.
