             3.10. ELECTION TO PROTECTION ONE'S BOARD OF DIRECTORS. From and
     after October 25, 2001, the Protection One Board of Directors shall have
     not less than nine directors nor more than twelve directors, as determined
     from time to time by the Board of Directors. From and after October 25,
     2001, and for so long as Western shall own, directly or indirectly, more
     than 50 percent of the issued and outstanding Common Stock of Protection
     One, Western shall vote all shares of Common Stock beneficially owned by
     Western to elect, and Protection One shall use its best efforts to cause to
     be elected, (i) one individual selected from the executive officers of
     Protection One, (ii) at least three individuals who are independent persons
     ("Independent Directors") and (iii) the number of individuals selected by
     Western necessary to fill the remaining positions on the Board of Directors
     (some or all of whom, at Western's sole discretion, may be "independent
     persons"). For purposes of this Agreement, "independent persons" shall mean
     a person who (i) is in fact independent, (ii) does not have any direct
     financial interest or any material indirect financial interest in Western,
     Protection One or any entity or person that beneficially owns greater than
     two percent of the outstanding Protection One Common Stock or any of their
     respective affiliates, and (iii) is not connected with Western, Protection
     One or any entity or person that beneficially owns greater than two percent
     of the outstanding Protection One Common Stock or any of their respective
     affiliates as an officer, employee, consultant, agent, representative,
     trustee, partner, director (other than of Protection One) or person
     performing similar functions. Any vacancy resulting from a person selected
     by Western no longer serving as a director may be filled from time to time
     by the remaining directors selected by Western then serving on the Board of
     Directors. The Chairman of the board of directors of Protection One at all
     times shall be a person selected by Western.

     Section 2.  REPRESENTATIONS AND WARRANTIES. Each party hereto hereby
represents and warrants that (i) it has the power and authority and the legal
right to make, deliver and perform this Amendment, (ii) it has taken all
necessary actions to authorize the execution, delivery and performance of this
Amendment, and (iii) this Amendment is legal, valid and binding on, and
enforceable against, such party.

     Section 3.  CONTINUING EFFECT. Except as expressly waived or otherwise
agreed hereby, the Contribution Agreement shall continue to be and shall remain
in full force and effect in accordance with its terms. This Amendment shall be
limited precisely as drafted and shall not constitute a waiver or amendment of
any other term, condition or provision of the Contribution Agreement.

construed and interpreted in accordance with, the laws of the
State of Delaware (without regard to principles of conflict laws).
