Subject to the terms and conditions set forth herein, Lender agrees to make available to Borrower until the Maturity Date a revolving line of credit providing for Advances in an aggregate principal amount not exceeding the Commitment at any time. Until the Maturity Date, Borrower may borrow, repay and reborrow Advances within the Commitment. This agreement is executed in replacement and substitution for that certain Credit Agreement dated as of November 3, 1993, as amended, among the Borrower, Protection One Alarm Services, Inc. and Heller Financial, Inc., as agent and as lender, and certain other lenders. B. Base Rate Advances and LIBOR Advances made under this facility shall mature no later than the Maturity Date.

PROTECTION ONE ALARM MONITORING, INC. April 1, 1998 Page 2 C. Unless Lender shall otherwise agree in writing, net proceeds from any equity offering by Protection One, Inc., a Delaware corporation and Borrower's corporate parent ("Parent"), shall be used to repay outstanding Advances and the Commitment shall be permanently reduced, unless otherwise agreed to by Borrower and Lender, by the amount of Lender's participation in such equity offering. D.

In case of prepayment of an Advance, or upon the failure to borrow an Advance after having given notice thereof, Borrower shall, upon demand, compensate Lender for any funding losses arising from any funding commitment made by Lender with respect to such Advance to Borrower and arising from Borrower's prepayment or failure to borrow such Advance. F. Obligations of the Borrower to repay Advances shall be evidenced by a Note executed by the Borrower payable to the order of the Lender representing the Borrower's obligation to pay the Lender's Commitment or, if less, the aggregate unpaid principal amount of all Advances made by the Lender to the Borrower, plus interest on such principal amounts and all other fees, charges and other amounts due thereon. The Note shall be dated the date hereof, shall bear interest on the unpaid principal amount thereof at the applicable interest rate specified in this agreement and otherwise shall be in the form attached hereto as Exhibit A.

No WIBOR Advance shall expire later than 90 days after the Maturity Date, provided however, that if this agreement is not amended and restated prior to the Maturity Date to extend the Maturity Date beyond the expiration date of any outstanding Advances, all outstanding Advances as of the Maturity Date, together with accrued interest and fees thereon, shall be due and payable on the Maturity Date. B. Upon four Business Days' prior notice given before 1:00 p.m. (Central time), a LIBOR Advance may be continued on the last day of its interest period as a LIBOR Advance, or a Base Rate Advance or WIBOR Advance may be converted into a LIBOR Advance.

If at any time Lender, in its sole discretion, determines that adequate resources are not available to support the lending of WIBOR Advances, Lender's obligation to make WIBOR Advances shall cease during such period.

All payments to Lender shall be made at 818 South Kansas Avenue, Topeka, Kansas 66612, or such other location or bank account(s) as Lender may from time to time specify in same day funds not later than 12:00 noon (Central time).
