Re:    Request for Waiver

Gentlemen:

Reference is hereby made to that certain Credit  Agreement  dated as of December
21,  1998,  executed  by  Protection  One Alarm  Monitoring,  Inc.,  a  Delaware
corporation  ("Borrower"),  NationsBank,  N.A.  (now  known as Bank of  America,
N.A.), as Administrative Agent  ("Administrative  Agent"), the Syndication Agent
defined  therein,  the  Documentation  Agent  defined  therein,  and the Lenders
defined therein (as modified, amended, renewed, extended, and restated from time
to time, the "Credit  Agreement").  Capitalized terms used herein shall,  unless
otherwise  indicated,  have the  respective  meanings  set  forth in the  Credit
Agreement.

Borrower  has notified  Administrative  Agent that,  as of  September  30, 1999,
Borrower may not be in compliance  with the Leverage  Ratio set forth in Section
10.13(a) of the Credit  Agreement and the Interest  Coverage  Ratio set forth in
Section 10.13(b) of the Credit Agreement (the "Covenant Violations").

By execution of this letter in the space provided below,  each Lender  executing
this  letter  (collectively,  "Consenting  Lenders"),  subject  to the terms and
conditions  of  this  letter,  hereby  waives  the  existence  of  the  Covenant
Violations and any Default created thereby until 5:00 p.m. (Dallas,  Texas time)
on November 1, 1999.

As a condition  precedent to each Consenting  Lender's execution of this letter,
Borrower hereby notifies  Administrative  Agent that, pursuant to Section 2.3 of
the  Credit  Agreement,   Borrower  elects  to  partially  terminate  the  Total
Commitment in an amount equal to  $250,000,000  and, after giving effect to such
partial termination, the Total Commitment shall equal $250,000,000. Borrower and
Consenting  Lenders agree that such partial  termination of the Total Commitment
shall  be  effective  as  of  the  date  hereof   (notwithstanding   the  notice
requirements set forth in Section 2.3 of the Credit Agreement.

As a material inducement to the Credit Parties to execute this letter,  Borrower
hereby  represents and warrants to the Credit Parties that,  after giving effect
to this  letter and the waiver  contained  herein:  (a) other than the  Covenant
Violations,  all of the representations  and warranties  contained in the Credit
Agreement  and the other  Loan  Documents  are true and  correct  as of the date
hereof as though made as of such date (unless  they speak to a specific  date or
are based upon facts which have changed by transactions  expressly  contemplated
or  permitted  by the  Credit  Agreement);  and  (b)  other  than  the  Covenant
Violations, no Potential Default or Default exists.
