                              W I T N E S S E T H

     WHEREAS, contemporaneously with the execution and delivery of this
Amendment, the Company intends to enter into an Agreement and Plan of Merger,
dated as of the date hereof (the "Merger Agreement"), with Securitas AB, a
joint stock company organized under the laws of Sweden ("Parent"), and
Securitas Acquisition Corporation, a Delaware corporation and an indirect,
wholly owned subsidiary of Parent ("Purchaser"), which provides for, upon the
terms and subject to the conditions set forth therein, (i) the commencement by
Purchaser of a tender offer for all of the issued and outstanding shares of
common stock, par value $.01 per share (the "Common Stock"), of the Company,
including the associated rights (the "Rights") to purchase Series A
Participating Cumulative Preferred Stock issued under the Rights Agreement and
(ii) the subsequent merger of Purchaser with and into the Company;

     WHEREAS, the Merger Agreement also contemplates that the Rights Agreement
shall be amended to provide that (i) neither the Merger Agreement, the related
stock option agreement between the Company and Parent or the related
stockholders' agreement among certain stockholders of the Company, Parent and
Purchaser, nor any of the transactions contemplated thereby, will result in the
occurrence of a "Distribution Date" (as defined in the Rights Agreement) or
otherwise cause the Rights to become exercisable by the holders thereof and
(ii) the Rights shall automatically terminate on and as of the Effective Time
(as defined in the Merger Agreement), and be void and of no further force or
effect;

     WHEREAS, no Person is currently deemed to be an "Acquiring Person" (as
defined in the Rights Agreement) and the Rights are currently redeemable by the
Board of Directors of the Company;

     WHEREAS, Section 27 of the Rights Agreement provides in relevant part
that, for so long as the Rights are then redeemable, the Company may supplement
or amend any provision of the Rights Agreement in any respect without the
approval of any holders of certificates representing shares of Common Stock;
and

     WHEREAS, in connection with the foregoing, the parties hereto desire to
amend the Rights Agreement.
