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").  Pursuant
to a letter dated as of  September  30, 1999,  the Required  Lenders  waived the
existence of the Covenant  Violations  until 5:00 p.m.  (Dallas,  Texas time) on
November 1, 1999 (the "Waiver Period").

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 extend the Waiver Period until 5:00 p.m.
(Dallas, Texas time) on December 3, 1999.

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.

By execution of this letter in the space provided below,  Borrower  ratifies and
confirms  that the  Credit  Agreement  and all  other  Loan  Documents,  and all
renewals,  extensions,  and  restatements of, and amendments and supplements to,
any of the foregoing, are and remain in full force and effect in accordance with
their respective terms.

The waiver hereby granted by Consenting Lenders does not (a) constitute a waiver
or  modification  of any  other  terms or  provisions  set  forth in the  Credit
Agreement  or any other  Loan  Document  and shall not impair any right that any
Credit Party may now or hereafter  have under or in  connection  with the Credit
Agreement or any other Loan  Document,  and (b) impair any Credit Party's rights
to insist  upon  strict  compliance  with the  Credit  Agreement,  as amended or
otherwise  modified  hereby,  or the other Loan  Documents.  The Loan  Documents
continue  to bind  and  inure to  Borrower  and the  Credit  Parties  and  their
respective successors and permitted assigns.

This  letter,  when  countersigned  by the  Required  Lenders,  shall be a "Loan
Document" as defined and referred to in the Credit  Agreement and the other Loan
Documents, and may be signed in any number of counterparts,  each of which shall
be deemed an original,  but all of which together  shall  constitute one and the
same  instrument.  THIS LETTER SHALL BE GOVERNED BY AND  CONSTRUED IN ACCORDANCE
WITH THE LAWS OF THE STATE OF TEXAS.

THIS  LETTER,  THE CREDIT  AGREEMENT,  AND THE OTHER LOAN  DOCUMENTS  EMBODY THE
FINAL, ENTIRE AGREEMENT AMONG THE PARTIES HERETO AND SUPERSEDE ANY AND ALL PRIOR
COMMITMENTS, AGREEMENTS, REPRESENTATIONS, AND UNDERSTANDINGS, WHETHER WRITTEN OR
ORAL,  RELATING TO THE SUBJECT MATTER  HEREOF,  AND MAY NOT BE  CONTRADICTED  OR
VARIED BY EVIDENCE OF PRIOR,  CONTEMPORANEOUS,  OR SUBSEQUENT ORAL AGREEMENTS OR
DISCUSSIONS  OF THE  PARTIES  HERETO.  THERE  ARE NO ORAL  AGREEMENTS  AMONG THE
PARTIES HERETO.

Please  execute a copy of this letter in the space provided below to acknowledge
