Ladies and Gentlemen:

          Protection One Alarm Monitoring, Inc. (the "Company") proposes to 
issue and sell to Morgan Stanley & Co. Incorporated, Chase Securities Inc., 
First Union Capital Markets, a division of Wheat First Securities, Inc., 
Nationsbanc Montgomery Securities LLC and TD Securities (USA) Inc. 
(collectively, the "Placement Agents") an aggregate of $350,000,000 in 
aggregate principal amount of 8 1/8% Senior Subordinated Notes due 2009 (the 
"Initial Notes"), subject to the terms and conditions set forth herein. The 
Initial Notes will be issued pursuant to an Indenture (the "Indenture"), to 
be dated the Closing Date (as defined), among the Company, the Guarantors (as 
defined) and The Bank of New York, as trustee (the "Trustee"). The Notes (as 
defined) will be fully and unconditionally guaranteed (the "Guarantees") as 
to payment of principal, interest, and premium, if any, on an unsecured 
senior subordinated basis, jointly and severally, by each entity listed on 
Exhibit A hereto (collectively, the "Guarantors"). Capitalized terms used 
herein and not otherwise defined shall have the meanings assigned to such 
terms in the Indenture.

                                       1


         The net proceeds to the Company from the sale to the Placement 
Agents of the Initial Notes (the "Proceeds") will be used by the Company: (i) 
to repay a portion of the Senior Credit Facility (as defined) and (ii) for 
general purposes and working capital.

          1.   ISSUANCE OF SECURITIES. The Company proposes, upon the terms 
and subject to the conditions set forth herein, to issue and sell to the 
Placement Agents an aggregate of $350,000,000 in aggregate principal amount 
of Initial Notes. The Initial Notes and the Exchange Notes (as defined) 
issuable in exchange therefor are collectively referred to herein as the 
"Notes."

          Upon original issuance thereof, and until such time as the same is 
no longer required under the applicable requirements of the Securities Act of 
1933, as amended (the "Act"), the Initial Notes (and all securities issued in 
exchange therefor or in substitution thereof) shall bear the following legend:

          THIS NOTE HAS NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF
1933, AS AMENDED (THE "SECURITIES ACT"), AND ACCORDINGLY, MAY NOT BE OFFERED OR
SOLD WITHIN THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF, U.S.
PERSONS EXCEPT AS SET FORTH IN THE FOLLOWING SENTENCE.  BY ITS ACQUISITION
HEREOF, THE HOLDER (1) REPRESENTS THAT (A) IT IS A "QUALIFIED INSTITUTIONAL
BUYER" (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) OR (B) IT IS AN
INSTITUTIONAL "ACCREDITED INVESTOR" (AS DEFINED IN RULE 501 (a)(1), (2), (3) OR
(7) OF REGULATION D UNDER THE SECURITIES ACT) (AN "INSTITUTIONAL ACCREDITED
INVESTOR") OR (C) IT IS NOT A U.S. PERSON AND IS ACQUIRING THIS NOTE IN AN
OFFSHORE TRANSACTION IN COMPLIANCE WITH REGULATION S UNDER THE SECURITIES ACT,
(2) AGREES THAT IT WILL NOT, WITHIN THE TIME PERIOD REFERRED TO UNDER RULE
144(k) UNDER THE SECURITIES ACT AS IN EFFECT ON THE DATE OF THE TRANSFER OF THIS
NOTE, RESELL OR OTHERWISE TRANSFER THIS NOTE EXCEPT (A) TO THE COMPANY OR ANY
SUBSIDIARY THEREOF, (B) TO A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH
RULE 144A UNDER THE SECURITIES ACT, (C) INSIDE THE UNITED STATES TO AN
INSTITUTIONAL ACCREDITED INVESTOR THAT, PRIOR TO SUCH TRANSFER, FURNISHES TO THE
TRUSTEE A SIGNED LETTER CONTAINING CERTAIN REPRESENTATIONS AND AGREEMENTS
RELATING TO THE RESTRICTIONS ON TRANSFER OF THIS NOTE (THE FORM OF WHICH LETTER
CAN BE OBTAINED FROM THE TRUSTEE), AND, IF SUCH TRANSFER IS IN RESPECT OF AN
AGGREGATE PRINCIPAL AMOUNT OF LESS THAN $100,000, AN OPINION OF COUNSEL
ACCEPTABLE TO THE COMPANY THAT SUCH TRANSFER IS IN COMPLIANCE WITH THE
SECURITIES ACT, (D) OUTSIDE THE UNITED STATES IN AN OFFSHORE TRANSACTION IN
COMPLIANCE WITH RULE 904 UNDER THE SECURITIES ACT, (E) PURSUANT TOT HE EXEMPTION
FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT (IF 

                                       2


AVAILABLE) OR (F) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE 
SECURITIES ACT AND (3) AGREES THAT IT WILL DELIVER TO EACH PERSON TO WHOM 
THIS NOTE IS TRANSFERRED A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. 
 IN CONNECTION WITH ANY TRANSFER OF THIS NOTE WITHIN THE TIME PERIOD REFERRED 
TO ABOVE, THE HOLDER MUST CHECK THE APPROPRIATE BOX SET FORTH ON THE REVERSE 
HEREOF RELATING TO THE MANNER OF SUCH TRANSFER AND SUBMIT THIS CERTIFICATE TO 
THE TRUSTEE.  IF THE PROPOSED TRANSFEREE IS AN INSTITUTIONAL ACCREDITED 
INVESTOR, THE HOLDER MUST, PRIOR TO SUCH TRANSFER, FURNISH TO THE TRUSTEE AND 
THE COMPANY SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS 
EITHER OF THEM MAY REASONABLY REQUIRE TO CONFIRM THAT SUCH TRANSFER IS BEING 
MADE PURSUANT TO AN EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE 
REGISTRATION REQUIREMENTS OF THE SECURITIES ACT.  AS USED HEREIN, THE TERMS 
"OFFSHORE TRANSACTION," "UNITED STATES" AND "U.S. PERSON" HAVE THE MEANINGS 
GIVEN TO THEM BY REGULATION S UNDER THE SECURITIES ACT.  THE INDENTURE 
CONTAINS A PROVISION REQUIRING THE TRUSTEE TO REFUSE TO REGISTER ANY TRANSFER 
OF THIS NOTE IN VIOLATION OF THE FOREGOING RESTRICTIONS.

          2.   OFFERING. The Initial Notes will be offered and sold to the 
Placement Agents pursuant to an exemption from the registration requirements 
under the Act. The Company has prepared a preliminary offering memorandum, 
dated December 10, 1998 (the "Preliminary Offering Memorandum"), and a final 
offering memorandum, dated December 16, 1998 (the "Offering Memorandum"), 
relating to the Company, the Guarantors and their respective subsidiaries and 
the Initial Notes.

          The Placement Agents have advised the Company that the Placement 
Agents will make offers (the "Exempt Resales") of the Initial Notes on the 
terms set forth in the Offering Memorandum, as amended or supplemented, 
solely to persons whom the Placement Agents reasonably believe to be (i) in 
the case of offers inside the United States, "qualified institutional 
buyers," as defined in Rule 144A under the Act ("QIBs") and (ii)  in the case 
of offers outside the United States, to persons other than U.S. persons 
("foreign purchasers," which term shall include dealers or other professional 
fiduciaries in the United States acting on a discretionary basis for foreign 
beneficial owners (other than an estate or trust)) in reliance upon 
Regulation S under the Securities Act that, in each case, in purchasing such 
Initial Notes are deemed to have represented and agreed as provided in the 
Offering Memorandum under the caption "Transfer Restrictions".  The QIBs and 
the foreign purchasers are referred to herein as the "Eligible Purchasers." 
The Placement Agents will offer the Initial Notes to such Eligible Purchasers 
initially at a price equal to 100% of the principal amount thereof. Such 
price may be changed at any time without notice.

                                       3


          Holders (including subsequent transferees) of Initial Notes will 
have the registration rights set forth in the registration rights agreement 
relating thereto (the "Registration Rights Agreement"), to be dated the 
Closing Date. Pursuant to the Registration Rights Agreement, the Company and 
the Guarantors will agree to file with the Securities and Exchange Commission 
(the "Commission"), under circumstances set forth therein, (i) a registration 
statement under the Act (the "Exchange Offer Registration Statement"), 
relating to the 8 1/8% Exchange Senior Subordinated Notes due 2009 (the 
"Exchange Notes") to be offered in exchange for the Initial Notes (the 
"Exchange Offer") or (ii) a shelf registration statement pursuant to Rule 415 
under the Act (each of the "Shelf Registration Statement" and the Exchange 
Offer Registration Statement, being referred to as a "Registration 
Statement"), relating to the resale by certain holders of the Initial Notes, 
and to use their best efforts to cause such Registration Statements to be 
declared effective and to consummate the Exchange Offer. This Agreement, the 
Notes, the Guarantees, the Indenture and the Registration Rights Agreement 
are hereinafter referred to collectively as the "Operative Documents."

          3.   DELIVERY AND PAYMENT. On the basis of the representations, 
warranties and covenants contained in this Agreement, and subject to its 
terms and conditions, the Company agrees to issue and sell to the Placement 
Agents, and each Placement Agent agrees, severally and not jointly, to 
purchase from the Company, the principal amount of Initial Notes set forth 
opposite its name on Schedule I hereto. The purchase price for the Initial 
Notes will be $980 per $1,000 principal amount of Initial Note.

          Delivery of the Initial Notes shall be made, against payment of the 
purchase therefor, at the offices of Weil, Gotshal & Manges, 100 Crescent 
Court, Suite 1300, Dallas, Texas or such other location as may be mutually 
acceptable. Such delivery and payment shall be made at 9:00 a.m., Dallas time 
or 10:00 a.m. New York City time on December 21, 1998 or at such other time 
as shall be agreed upon by the Placement Agents and the Company. The time and 
date of such delivery and payment are herein called the "Closing Date."

          On the Closing Date, one or more Initial Notes in definitive form, 
registered in the name of Cede & Co., as nominee of The Depository Trust 
Company ("DTC"), having an aggregate amount corresponding to the aggregate 
amount of the Initial Notes sold pursuant to the Exempt Resales to Eligible 
Purchasers (the "Global Notes") shall be delivered by the Company to the 
Placement Agents (or as the Placement Agents may direct), against payment by 
the Placement Agents of the purchase price therefor, by wire transfer of same 
day funds, to an account designated by the Company; provided, however, that 
the Company shall give at least two business days' prior written notice to 
the Placement Agents of the information required to effect such wire 
transfer. The Global Notes shall be made available to the Placement Agents 
for inspection not later than 10:00 a.m., New York City time, on the business 
day immediately preceding the Closing Date.

                                       4


          4.   CERTAIN COVENANTS OF THE COMPANY AND THE GUARANTORS. Each of 
the Company and the Guarantors, jointly and severally, covenants and agrees:

               (a)  To advise the Placement Agents promptly and, if requested 
by the Placement Agents, confirm such advice in writing, (i) of the issuance 
by any state securities commission of any stop order suspending the 
qualification or exemption from qualification of  any Notes for offering or 
sale in any jurisdiction, or the initiation of any proceeding for such 
purpose by any state securities commission or other regulatory authority and 
(ii) of the happening of any event known to the Company or the Guarantors on 
or before the Closing Date which in the judgement of the Company and the 
Guarantors would require the making of any change in the Offering Memorandum 
or in the information incorporated by reference therein so that as therefore 
delivered to purchasers the Offering Memorandum will not include any untrue 
statement of material fact or omit to state a material fact necessary in 
order to make the statements therein, in the light of the circumstances under 
which they are made, not misleading, and on request to prepare and furnish to 
the Placement Agents and to dealers and other persons designated by the 
Placement Agents such amendments or supplements (including appropriate 
filings under the Exchange Act) to the Offering Memorandum as may be 
necessary to any such change, provided that the Company shall be so obligated 
subsequent to the time of purchase only so long as the Company is notified of 
unsold allotments (failure by the Placement Agents to so notify the Company 
cancels the Company's obligation under this Section 4(a)). The Company and 
the Guarantors shall use their respective reasonable best efforts to prevent 
the issuance of any stop order or order suspending the qualification or 
exemption of any Notes under any state securities or Blue Sky laws and, if at 
any time any state securities commission or other regulatory authority shall 
issue an order suspending the qualification or exemption of any Notes or the 
Guarantees under any state securities or Blue Sky laws, the Company and the 
Guarantors shall use their respective reasonable best efforts to obtain the 
withdrawal or lifting of such order at the earliest possible time.

               (b)  To as soon as practicable, make generally available to 
its security holders an earnings statement (as contemplated by Rule 158 under 
the Act) covering a period of twelve months after the effective date (as the 
term "effective date" is defined in Rule 158) of the Offering Memorandum.

               (c)  To furnish such proper information as may be required and 
otherwise to cooperate in qualifying the Initial Notes for sale under the 
laws of such jurisdictions as the Placement Agents may designate and in 
determining their eligibility for investment under the laws of such 
jurisdiction; provided that the Company and the Guarantors shall not hereby 
be required to qualify as a foreign corporation or to file a general consent 
to service of process in any jurisdiction.

               (d)  To deliver to the Placement Agents without charge as soon as
practicable after the execution and delivery of this Agreement and thereafter to
furnish to the 


                                       5


Placement Agents, without charge, as many copies of the Offering Memorandum 
in final form and any documents incorporated by reference therein at or after 
the date thereof, as the Placement Agents may reasonably request from time to 
time in connection with Exempt Resales.

               (e)  To pay the reasonable fees and expenses of counsel for 
the Placement Agents, and to reimburse the Placement Agents for their 
reasonable out-of-pocket expenses incurred in contemplation of the 
performance of this Agreement, in the event that the Initial Notes are not 
delivered to and taken up and paid for by the Placement Agents hereunder for 
any reason whatsoever except the failure or refusal of any Placement Agent to 
take up and pay for the Initial Notes (i) pursuant to the terms of Section 
6(b) or (ii) for some reason not permitted by the terms of this Agreement, 
the Placement Agents agreeing to pay the fees and expenses of counsel for the 
Placement Agents in any other event. Whether or not the transactions 
contemplated in this Agreement are consummated or this Agreement is 
terminated, to pay or cause to be paid all expenses incident to the 
performance of its obligations under this Agreement (other than transfer 
taxes payable on resale of the Initial Notes by the Placement Agents and fees 
and disbursements of counsel for the Placement Agents, except as set forth in 
the preceding sentence), including: (i) the fees, disbursements and expenses 
of the counsel and accountants for the Company and each of the Guarantors in 
connection with the issuance and sale of the Notes and all other fees or 
expenses in connection with the preparation of the Preliminary Offering 
Memorandum and the Offering Memorandum and all amendments and supplements 
thereto, including all printing costs associated therewith, and the 
delivering of copies thereof to the Placement Agents, in the quantities 
herein above specified, (ii) all costs and expenses related to the transfer 
and delivery of the Initial Notes to the Placement Agents, including any 
transfer or other taxes payable thereon, (iii) the cost of printing or 
producing any Blue Sky or legal investment memorandum in connection with the 
offer and sale of the Initial Notes under state securities laws and all 
expenses in connection with the qualification of the Initial Notes for offer 
and sale under state securities laws as provided in Section 4( c) hereof, 
including filing fees and the reasonable fees and disbursements of counsel 
for the Placement Agents (not to exceed $3,000) in connection with such 
qualification and in connection with the Blue Sky or legal investment 
memorandum, (iv) any fees charged by rating agencies for the rating of the 
Notes, (v) all document production charges and expenses of counsel to the 
Placement Agents (but not including their fees for professional services) in 
connection with the preparation of this Agreement, (vi) the fees and 
expenses, if any, incurred in connection with the admission of the Initial 
Notes for trading in PORTAL or any appropriate market system, (vii) the costs 
and charges of the trustee and any transfer agent, registrar or depositary, 
(viii) the cost of the preparation, issuance and delivery of the Initial 
Notes, (ix) the costs and expense of the Company relating to investor 
presentations on any "road show" undertaken in connection with the marketing 
of the offering of the Initial Notes, including, without limitation, expenses 
associated with the production of road show slides and graphics, fees and 
expenses of any consultants engaged in connection with 

                                       6


the road show presentations with the prior approval of the Company, travel 
and lodging expenses of the representatives and officers of the Company and 
any such consultants, and one-half of the cost of any aircraft chartered in 
connection with the road show with the prior approval of the Company, and (x) 
all other costs and expenses incident to the performance of the obligations 
of the Company and the Guarantors hereunder for which provision is not 
otherwise made in this Section.

               (f)  To use the proceeds from the sale of the Initial Notes in 
the manner described in the Offering Memorandum under the caption "Use of 
Proceeds."

               (g)  Not to sell, offer for sale or solicit offers to buy or 
otherwise negotiate in respect of any security (as defined in the Act) that 
would be integrated with the sale of the Initial Notes in a manner that would 
require the registration under the Act of the sale to the  Placement Agents 
or the Eligible Purchasers of the Initial Notes or to take any other action 
that would result in the Exempt Resales not being exempt from registration 
under the Act.

               (h)  For so long as any of the Notes remain outstanding and 
during any period in which the Company and the Guarantors are not subject to 
Section 13 or 15(d) of the Securities Exchange Act of 1934, as amended (the 
"Exchange Act"), to make available to any holder or beneficial owner of 
Initial Notes in connection with any sale thereof and any prospective 
purchaser of such Notes from such holder or beneficial owner, upon request of 
such holder, the information required by Rule 144A(d) (4) under the Act.

               (i)  To furnish to the Placement Agents, at or before the time 
of filing with the Commission subsequent to the date hereof and up to and 
including the Closing Date, a copy of any document proposed to be filed by

the Exchange Act.

               (j)  Not to take, directly or indirectly, any action designed 
to, or that might reasonably be expected to, cause or result in stabilization 
or manipulation of the price of any security of the Company or any of the 
Guarantors to facilitate the sale or resale of the Notes. Except as permitted 
by the Act, none of the Company or the Guarantors will distribute any (i) 
preliminary offering memorandum, including, without limitation, the 
Preliminary Offering Memorandum, (ii) offering memorandum, including, without 
limitation, the Offering Memorandum, or (iii) other offering material in 
connection with the offering and sale of the Notes.

               (k)  Not to solicit any offer to buy or offer or sell the 
Initial Notes by means of any form of general solicitation or general 
advertising (as those terms are used in Regulation D under the Act) or in any 
manner involving a public offering within the meaning of Section 4(2) of the 
Act.

               (l)  To use its reasonable best efforts to permit the Initial 
Notes to be designated PORTAL securities in accordance with the rules and 
regulations adopted by the National Association of Securities Dealers, Inc.

                                       7


               (m)  In connection with offers and sales to foreign purchasers 
in accordance with Regulation S, none of the Company, the Guarantors, their 
Affiliates or any person acting on any of their behalf (other than the 
Placement Agents) will engage in any directed selling efforts (as that term 
is defined in Regulation S) with respect to the Initial Notes, and the 
Company, the Guarantors, their Affiliates and each person acting on any of 
their behalf (other than the Placement Agents) will comply with the offering 
restrictions requirement of Regulation S.

               (m)  During the period of two years after the Closing Date, 
the Company will not, and will not permit any of its affiliates (as defined 
in Rule 144 under the Securities Act) to resell any of the Securities which 
constitute "restricted securities" under Rule 144 that have been reacquired 
by any of them.

          5.   CONDITIONS OF PLACEMENT AGENTS' OBLIGATIONS. The several 
obligations of the Placement Agents to purchase and pay for the Initial 
Notes, as provided herein, shall be subject to the following conditions:

               (a)  Subsequent to the execution and delivery of this 
Agreement and prior to the Closing Date:

                    (i)   there shall have not occurred any downgrading, nor
               shall any notice have been given of any intended or potential
               downgrading or of any review for a possible change that does not
               indicate the direction of the possible change, in the rating
               accorded any of Protection One or the Company's securities by any
               "nationally recognized statistical rating organization," as such
               term is defined for purposes of Rule 436(g)(2) under the Act; and

                    (ii)  there shall not have occurred any change, or any
               development reasonably likely to result in a change, in the
               condition, financial or otherwise, or in the earnings, business
               or operations of the Company and the Guarantors, taken as a
               whole, from that set forth in the Offering Memorandum (exclusive
               of any amendments or supplements thereto subsequent to the date
               of this Agreement) that, in the Placement Agents' judgment, is
               material and adverse and that makes it, in the Placement Agents'
               judgment, impracticable to market the Initial Notes on the terms
               and in the manner contemplated in the Offering Memorandum.

               (b)  The Placement Agents shall have received on the Closing 
Date certificates from each of the Company and Protection One, as the case 
may be, to the effect set forth in Section 5(a)(i) and to the effect that the 
representations and warranties of the Company and the Guarantors contained in 
this Agreement are true and correct as of the Closing Date and 

                                       8


the Company and the Guarantors have complied with all of the agreements and 
satisfied all of the conditions on its part to be performed or satisfied 
hereunder on or before the Closing Date.

               The officer signing and delivering such certificate may rely 
upon the best of his or her knowledge as to proceedings threatened.

               (c)  The Placement Agents shall have received on the Closing 
Date an opinion, dated the Closing Date, in form and substance reasonably 
satisfactory to the Placement Agents and counsel for the Placement Agents, of 
Weil, Gotshal & Manges LLP, counsel for the Company and the Guarantors, to 
the effect set forth in Exhibit B hereto.

               (d)  The Placement Agents shall have received on the Closing 
Date an opinion, dated on the Closing Date, in form and substances reasonably 
satisfactory to the Placement Agents and counsel for the Placement Agents, of 
Renee T. Kingsley, Vice President-Legal Services and Chief Counsel for the 
Company and the Guarantors, to the effect set forth in Exhibit C hereto.

               (e)  The Placement Agents shall have received an opinion, 
dated the Closing Date, in form and substance reasonably satisfactory to the 
Placement Agents, of Shearman & Sterling, counsel for the Placement Agents, 
covering such matters as are customarily covered in such opinions.

               (f)  At the time this Agreement is executed and at the Closing 
Date, the Placement Agents shall have received from Arthur Andersen LLP, 
independent public accountants, dated as of the date of this Agreement and as 
of the Closing Date, customary comfort letters addressed to the Placement 
Agents and in form and substance reasonably satisfactory to the Placement 
Agents and counsel for the Placement Agents with respect to the financial 
statements and certain financial information of the Company, the Guarantors 
and their respective subsidiaries contained or incorporated by reference in 
the Offering Memorandum.

               (g)  Shearman & Sterling shall have been furnished with such 
documents, in addition to those set forth above, as they may reasonably 
require for the purpose of enabling them to review or pass upon the matters 
referred to in this Section 5 and in order to evidence the accuracy, 
completeness or satisfaction in all material respects of any of the 
representations, warranties or conditions herein contained.

               (h)  The Company, the Guarantors and the Trustee shall have 
entered into the Indenture, which shall be in full force and effect on the 
Closing Date.

               (i)  The Company and the Guarantors shall have entered into

          6.   TERMINATION OF AGREEMENT.

               This Agreement shall be subject to termination by notice given 
by the Placement Agents to the Company and Protection One, if (a) after the

and (b) in the case of any of the events specified in clauses 6(a)(i) through 
6(a)(iv), such event, singly or together with any other such event, makes it, 
in the Placement Agents' judgment, impracticable to market the Notes on the 
terms and in the manner contemplated in the Offering Memorandum.

          7.   WARRANTIES AND REPRESENTATIONS OF THE COMPANY AND THE 
GUARANTORS. Each of the Company and the Guarantors, severally and jointly,

offered for sale, solicited offers to buy or otherwise 

                                       10

adverse effect on the Company and the Guarantors, taken as a whole.

                                       11


               (i)  This Agreement has been duly authorized, executed and 
delivered by the Company and each Guarantor.

creditors' rights generally and general principles of equity and except as 
rights to indemnification and contribution under the Registration Rights

               (n)  The execution and delivery by the Company and each 
Guarantor of, and the performance by the Company and each Guarantor of its 
obligations under, this Agreement, the Indenture, the Registration Rights

                                       12


taken as a whole, and no consent, approval, authorization or order of, or 
qualification with, any governmental body or agency is required for the 
performance by the Company and each Guarantor of its respective obligations 
under this Agreement, the Indenture, the Registration Rights Agreement, the 
Notes (in the case of the Company) or the Guarantees (in the case of the

the Company and the Guarantors, taken as a whole, and such as may be required

laws with respect to the Company's obligations under the Registration Rights 
Agreement.

               (o)  There has not occurred any material adverse change, or 
any development involving a prospective material adverse change, in the

of the Company and the Guarantors, taken as a whole, from that set forth in 
the Final Memorandum (exclusive of any amendments or supplements thereto 
subsequent to the date of this Agreement).

               (p)  DSC Enterprises, Inc. is not a "Significant Subsidiary"

reliance.

          8.   WARRANTIES AND REPRESENTATIONS OF THE PLACEMENT AGENTS.  Each 
of the Placement Agents, severally and not jointly, represents, warrants and 
covenants to the Company and agrees that:

               (a)  Such Placement Agent is a QIB, with such knowledge and 
experience in financial and business matters as are necessary in order to 
evaluate the merits and risks of an investment in the Initial Notes.

               (b)  Such Placement Agent is not acquiring the Initial Notes

(within the meaning of Regulation D under the Act) has been or will be used 
by such Placement Agent or any of its representatives in connection with the 
offer and sale of any of the Initial Notes, including, but not limited to, 
articles, notices or other communications published in any newspaper, 
magazine, or similar medium or broadcast over television or radio, or any 
seminar or meeting whose attendees have been invited by any general 
solicitation or general advertising.

                                       13


               (d)  Each of the Placement Agents agrees that, in connection

further (A) agrees that it will offer to sell the Initial Notes only to, and 
will solicit offers to buy the Initial Notes only from, persons that it 
reasonably believes to be Eligible Purchasers, (B) acknowledges and agrees

to the Company or any subsidiary thereof, (ii) to a QIB in compliance with 
Rule 144A, (iii) inside the United States to an institutional "accredited

("Accredited Investor") that, prior to such transfer, furnishes to the 
Trustee a signed letter containing representations and agreements relating to 
the restrictions on transfer of the Initial Notes (the form of which letter

the Act, (iv) outside the United States in compliance with Rule 904 under the 
Act, (v) pursuant to the exemption from registration provided by Rule 144 
under the Act (if available) or (vi) pursuant to an effective registration 
statement under the Act and in accordance with any applicable security laws 
of any state of the United States or any other applicable jurisdiction and 
(C) acknowledges that it will, and each subsequent holder is required to, 
notify any purchaser of the security evidenced thereby of the resale 
restrictions forth in (B) above.

               (e)  Each Placement Agent, severally and not jointly, 
represents, warrants, and agrees with respect to offers and sales outside the 
United States that:

                    (i)   such Placement Agent understands that no action has
               been or will be taken in any jurisdiction by the Company that
               would permit a public offering of the Initial Notes, or
               possession or distribution of the Preliminary Offering Memorandum
               or the Offering Memorandum or any other offering or publicity
               material relating to the Initial Notes, in any country or
               jurisdiction where action for that purpose is required;

                    (ii)  such Placement Agent will comply with all applicable
               laws and regulations in each jurisdiction in which it acquires,
               offers, sells or delivers Initial Notes or has in its possession
               or distributes the Preliminary Offering Memorandum or the
               Offering Memorandum or any such other material, in all cases at
               its own expense;

                    (iii) the Initial Notes have not been registered under the
               Act and may not be offered or sold within the United States or
               to, or for the account or benefit of, U.S. persons except in
               accordance with Rule 144A or Regulation S under the Act or
               pursuant to another exemption from the 
 
                                       14


               registration requirements of the Act and in accordance with 
               any applicable securities laws of any State in the United 
               States or any other applicable U.S. jurisdiction;

                    (iv)  such Placement Agent has offered the Initial Notes
               and will offer and sell the Initial Notes (A) as part of their

               the later of the commencement of the offering and the Closing
               Date only in accordance with Rule 903 of Regulation S or as
               otherwise permitted in Section 8(d); accordingly, neither such
               Placement Agent, its Affiliates nor any persons acting on its or
               their behalf have engaged or will engage in any directed selling
               efforts (within the meaning of Regulation S) with respect to the
               Initial Notes, and any such Placement Agent, its Affiliates and
               any such persons have complied and will comply with the offering
               restrictions requirement of Regulation S;

                    (v)   such Placement Agent has (A) not offered or sold and,
               prior to the date six months after the Closing Date, will not
               offer or sell any Initial Notes to persons in the United Kingdom
               except to persons whose ordinary activities involve them in
               acquiring, holding, managing or disposing of investments (as
               principal or agent) for the purposes of their businesses or
               otherwise in circumstances which have not resulted and will not
               result in an offer to the public in the United Kingdom within the
               meaning of the Public Offers of Securities Regulations 1995 (the
               "Regulations"); (B) complied and will comply with all applicable
               provisions of the Financial Services Act 1986 and the Regulations
               with respect to anything done by it in relation to the Initial
               Notes in, from or otherwise involving the United Kingdom, and (C)
               only issued or passed on and will only issue or pass on in the
               United Kingdom any document received by it in connection with the
               issue of the Initial Notes to a person who is of a kind described
               in Article 11(3) of the Financial Services Act 1986 (Investment
               Advertisements) (Exemptions) Order 1996 or is a person to whom
               such document may otherwise lawfully be issued or passed on;

                    (vi)  such Placement Agent understands that the Initial
               Notes have not been and will not be registered under the
               Securities and Exchange Law of Japan, and represents that it has
               not offered or sold, and agrees not to offer or sell, directly or
               indirectly, any Initial Notes in Japan or for the account of any
               resident thereof except pursuant to any exemption from the
               registration requirements of the Securities and Exchange Law of
               Japan and otherwise in compliance with applicable provisions of
               Japanese law; and

                                       15



                    (vii)     such Placement Agent agrees that, at or prior to
               confirmation of sales of the Initial Notes, it will have sent to
               each distributor, dealer or person receiving a selling
               concession, fee or other remuneration that purchases Initial
               Notes from it during the restricted period a confirmation or
               notice to substantially the following effect:

               "The Notes covered hereby have not been registered under the U.S.
     Securities Act of 1933 (the "Securities Act") and may not be offered and
     sold within the United States or to, or for the account or benefit of, U.S.
     persons (i) as part of their distribution at any time or (ii) otherwise
     until 40 days after the later of the commencement of the offering and the
     closing date of the offering, except in either case in accordance with
     Regulation S (or Rule 144A if available) under the Securities Act.  Terms
     used above have the meaning given to them by Regulation S."

               Terms used in this Section 8(e) and not defined have the 
meanings given to them by Regulation S.

               The Placement Agents acknowledge that the Company and, for 
purposes of the opinions to be delivered to the Placement Agents pursuant to 
Section 5 hereof, counsel for the Company and the Guarantors and counsel for 
the Placement Agents will rely upon the accuracy and truth of the foregoing 
representations and hereby consents to such reliance.

          9.   INDEMNIFICATION AND CONTRIBUTION.

               (a)  The Company and each Guarantor, jointly and severally, 
agree to indemnify and hold harmless each Placement Agent and each person, if 
any, who controls any Placement Agent within the meaning of either Section 15 
of the Act or Section 20 of the Exchange Act, from and against any and all 
losses, claims, damages and liabilities (including, without limitation, any 
legal or other expenses reasonably incurred in connection with defending or 
investigating any such action or claim) caused by any untrue statement or 
alleged untrue statement of a material fact contained in the Preliminary 
Offering Memorandum or the Offering Memorandum (as amended or supplemented if 
the Company and the Guarantors shall have furnished any amendments or 
supplements thereto), or caused by any omission or alleged omission to state 
therein a material fact necessary to make the statements therein in the light 
of the circumstances under which they were made not misleading, except 
insofar as such losses, claims, damages or liabilities are caused by any such 
untrue statement or omission or alleged untrue statement or omission based 
upon information relating to any Placement Agent furnished to the Company in 
writing by such Placement Agent expressly for use therein.

               (b)  Each Placement Agent agrees, severally and not jointly, 
to indemnify and hold harmless the Company and the Guarantors and their 
respective, directors, officers and each person, if any, who controls the 
Company or any such Guarantor within the 

                                       16


meaning of either Section 15 of the Act or Section 20 of the Exchange Act to 
the same extent as the foregoing indemnity from the Company to such Placement 
Agent, but only with reference to information relating to such Placement 
Agent furnished to the Company in writing by such Placement Agent expressly 
for use in the Preliminary Offering Memorandum or the Offering Memorandum or 
any amendments or supplements thereto.

               (c)  In case any proceeding (including any governmental 
investigation) shall be instituted involving any person in respect of which 
indemnity may be sought pursuant to Section 9(a) or 9(b), such person (the 
"INDEMNIFIED PARTY") shall promptly notify the person against whom such 
indemnity may be sought (the "INDEMNIFYING PARTY") in writing and the 
indemnifying party, upon request of the indemnified party, shall retain 
counsel reasonably satisfactory to the indemnified party to represent the 
indemnified party and any others the indemnifying party may designate in such 
proceeding and shall pay the reasonable fees and disbursements of such 
counsel related to such proceeding.  In any such proceeding, any indemnified 
party shall have the right to retain its own counsel, but the fees and 
expenses of such counsel shall be at the expense of such indemnified party 
unless (i) the indemnifying party and the indemnified party shall have 
mutually agreed to the retention of such counsel or (ii) the named parties to 
any such proceeding (including any impleaded parties) include both the 
indemnifying party and the indemnified party and representation of both 
parties by the same counsel would be inappropriate due to actual or potential 
differing interests between them.  It is understood that the indemnifying 
party shall not, in respect of the legal expenses of any indemnified party in 
connection with any proceeding or related proceedings in the same 
jurisdiction, be liable for the reasonable fees and expenses of more than one 
firm (in addition to any local counsel) for all such indemnified parties and 
that all such fees and expenses shall be reimbursed as they are incurred.  
Such firm shall be designated in writing by Morgan Stanley & Co. 
Incorporated, in the case of parties indemnified pursuant to Section 9(a), 
and by the Company, in the case of parties indemnified pursuant to Section 
9(b). The indemnifying party shall not be liable for any settlement of any 
proceeding effected without its written consent, but if settled with such 
consent or if there be a final judgment for the plaintiff, the indemnifying 
party agrees to indemnify the indemnified party from and against any loss or 
liability by reason of such settlement or judgment.  Notwithstanding the 
foregoing sentence, if at any time an indemnified party shall have requested 
an indemnifying party to reimburse the indemnified party for fees and 
expenses of counsel as contemplated by the second and third sentences of this 
paragraph, the indemnifying party agrees that it shall be liable for any 
settlement of any proceeding effected without its written consent if (i) such 
settlement is entered into more than 60 days after receipt by such 
indemnifying party of the aforesaid request, (ii) the indemnifying party has 
been provided with a copy of the proposed terms of the settlement at least 30 
days prior to such settlement being entered into and (iii) such indemnifying 
party shall not have reimbursed the indemnified party in accordance with such 
request prior to the date of such settlement; provided that the indemnifying 
party shall not be required to reimburse such amounts pursuant to a 
settlement effected without its consent pursuant to this sentence during the 
period that such indemnifying party is contesting such reimbursement 
obligation in good faith by appropriate proceedings.  No indemnifying party 
shall, without the prior written 

                                       17



consent of the indemnified party, effect any settlement of any pending or 
threatened proceeding in respect of which any indemnified party is or could 
have been a party and indemnity could have been sought hereunder by such 
indemnified party, unless such settlement includes an unconditional release 
of such indemnified party from all liability on claims that are the subject 
matter of such proceeding.

               (d)  To the extent the indemnification provided for in Section 
9(a) or 9(b) is unavailable to an indemnified party or insufficient in 
respect of any losses, claims, damages or liabilities referred to therein, 
then each indemnifying party under such paragraph, in lieu of indemnifying 
such indemnified party thereunder, shall contribute to the amount paid or 
payable by such indemnified party as a result of such losses, claims, damages 
or liabilities (i) in such proportion as is appropriate to reflect the 
relative benefits received by such indemnifying party from the offering of 
the Initial Notes or (ii) if the allocation provided by clause 9(d)(i) above 
is not permitted by applicable law, in such proportion as is appropriate to 
reflect not only the relative benefits referred to in clause 9(d)(i) above 
but also the relative fault of such indemnifying party in connection with the 
statements or omissions that resulted in such losses, claims, damages or 
liabilities, as well as any other relevant equitable considerations.  The 
relative benefits received by the Company and the Guarantors, on the one 
hand, and the Placement Agents, on the other hand, in connection with the 
offering of such Initial Notes shall be deemed to be in the same respective 
proportions as the net proceeds from the offering of such Initial Notes 
(before deducting expenses) received by the Company and the total discounts 
and commissions received by the Placement Agents in respect thereof, bear to 
the aggregate offering price of such Initial Notes. The relative fault of the 
Company and the Guarantors, on the one hand, and of the Placement Agents, on 
the other hand, shall be determined by reference to, among other things, 
whether the untrue or alleged untrue statement of a material fact or the 
omission or alleged omission to state a material fact relates to information 
supplied by the Company and the Guarantors or by the Placement Agents and the 
parties' relative intent, knowledge, access to information and opportunity to 
correct or prevent such statement or omission.  The Placement Agents' 
respective obligations to contribute pursuant to this Section 9 are several 
in proportion to the respective principal amount of Initial Notes they have 
purchased hereunder, and not joint.

               (e)  The Company, the Guarantors and the Placement Agents 
agree that it would not be just or equitable if contribution pursuant to this 
Section 9 were determined by PRO RATA allocation (even if the Placement 
Agents were treated as one entity for such purpose) or by any other method of 
allocation that does not take account of the equitable considerations 
referred to in Section 9(d). The amount paid or payable by an indemnified 
party as a result of the losses, claims, damages and liabilities referred to 
in Section 9(d) shall be deemed to include, subject to the limitations set 
forth above, any legal or other expenses reasonably incurred by such 
indemnified party in connection with investigating or defending any such 
action or claim. Notwithstanding the provisions of this Section 9, no 
Placement Agent shall be required to contribute any amount in excess of the 
amount by which the total price at which the Initial Notes resold by it in 
the initial placement of such Initial Notes were offered to 

                                       18


investors exceeds the amount of any damages that such Placement Agent has 
otherwise been required to pay by reason of such untrue or alleged untrue 
statement or omission or alleged omission. No person guilty of fraudulent 
misrepresentation (within the meaning of Section 11(f) of the Act) shall be 
entitled to contribution from any person who was not guilty of such 
fraudulent misrepresentation.  The remedies provided for in this Section 9 
are not exclusive and shall not limit any rights or remedies which may 
otherwise be available to any indemnified party at law or in equity.

               (f)  The indemnity and contribution provisions contained in 
this Section 9 and the representations, warranties and other statements of 
the Company and the Guarantors contained in this Agreement shall remain 
operative and in full force and effect regardless of (i) any termination of 
this Agreement, (ii) any investigation made by or on behalf of any Placement 
Agent or any person controlling any Placement Agent or by or on behalf of the 
Company or any Guarantor or any of their respective officers or directors or 
controlling persons and (iii) acceptance of and payment for any of the 
Initial Notes.

          10.  NOTICES. All statements, requests, notices and agreements

Notes from a Placement Agent or any subsequent holder thereof) any legal or 
equitable right, remedy or claim under or in respect of this Agreement or any 
provision herein contained.

          The term "successor" as used in this Agreement shall not include 
any purchaser, as such purchaser, of any Initial Notes from any Placement

                                                                      EXHIBIT B


                          OPINION OF COUNSEL FOR THE COMPANY

          The opinion of the counsel for the Company to be delivered pursuant 
to Section 5(c) of the Placement Agreement shall be to the effect that:

     A.   The Company has been duly incorporated, is validly existing as a 
corporation in good standing under the laws of the jurisdiction of its 
incorporation, has the corporate power and authority to own its property and 
to conduct its business as now being conducted.

     B.   Each of Protection One, Protection One International, Inc., 
Protection One Investments, Inc., Network Multi-Family Security Corporation 
and Comsec/Narragansett Security, Inc. (the "Delaware Guarantors")) has been 
duly incorporated, is validly existing as a corporation in good standing 
under the laws of the jurisdiction of its incorporation, has the corporate 
power and authority to own its property and to conduct its business as now 
being conducted

     C.    The Placement Agreement has been duly authorized, executed and 
delivered by the Company, the Delaware Guarantors and DSC Enterprises, Inc. 
(the "Other Guarantor" and, collectively with the Delaware Guarantors, the 
"Guarantors").

     D.   The Notes have been duly authorized by the Company and, when 
executed and authenticated in accordance with the provisions of the Indenture 
and delivered to and paid for by the Placement Agents in accordance with the 
terms of the Placement Agreement, will be valid and binding obligations of 
the Company, enforceable in accordance with their terms, subject to 
applicable bankruptcy, insolvency or similar laws affecting creditors' rights 
generally and general principles of equity, and will be entitled to the 
benefits of the Indenture and the Registration Rights Agreement.

     E.        The Guarantees have been duly authorized by the Guarantors 
and, upon execution and delivery of the Indenture by each Guarantor and, 
assuming due execution and authentication of the Notes in accordance with the 
Indenture, will be valid and binding obligations of the Guarantors, 
enforceable in accordance with their terms, subject to applicable bankruptcy, 
insolvency or similar laws affecting creditors' rights generally and general 
principles of equity, and will be entitled to the benefits of the Indenture 
and the Registration Rights Agreement.

     F.   Each of the Indenture and the Registration Rights Agreement has 
been duly authorized, executed and delivered by, and (assuming the due 
authorization, execution and delivery of the Indenture by the trustee and the 
Registration Rights Agreement by the Placementt Agents) is a valid and 
binding agreement of, the Company and each Guarantor, enforceable in 

                                       

                                      B-2

accordance with its terms, subject to applicable bankruptcy, insolvency or 
similar laws affecting creditors' rights generally and  general principles of 
equity and except as rights to indemnification and contribution under the 
Registration Rights Agreement may be limited under applicable law.

     G.   The execution and delivery by the Company and each Delaware 
Guarantor of, and the performance by the Company and each Delaware Guarantor 
of their obligations under, the Placement Agreement, the Indenture, the 
Registration Rights Agreement, the Notes (in the case of the Company) and the 
Guarantees (in the case of the Delaware Guarantors) will not contravene any 
provision of applicable New York, Delaware corporate or federal law 
(excluding federal securities laws, as to which no opinion is expressed in 
this paragraph G, and state securities or blue sky laws, as to which we 
express no opinion) or the certificate of incorporation or by-laws of the 
Company or any Delaware Guarantor or, to the best of such counsel's 
knowledge, any material agreement or other instrument binding upon the 
Company or any Delaware Guarantor, or, to the best of such counsel's 
knowledge, any judgment, order or decree of any governmental body, agency or 
court having jurisdiction over the Company or any Delaware Guarantor, and no 
consent, approval, authorization or order of, or qualification with, any New 
York, Delaware corporate or federal governmental body or agency is required 
for the performance by the Company and each Delaware Guarantor of their 
obligations under the Placement Agreement, the Indenture, the Registration 
Rights Agreement, the Notes (in the case of the Company) or the Guarantees 
(in the case of the Guarantors), except such as may be required by the 
Federal securities laws (as to which we express no opinion in this paragraph 
G) and securities or Blue Sky laws of the various states in connection with 
the offer and sale of the Notes and by Federal and state securities laws with 
respect to the obligations of the Company and the Delaware Guarantors under 
the Registration Rights Agreement.

     H.   Neither the Company nor Protection One is, or after giving effect 
to the offering and sale of the Notes and the application of the proceeds 
thereof as described in the Offering Memorandum, will be,  an "investment 
company" as such term is defined in the Investment Company Act of 1940, as 
amended.

     I.   The Indenture, the Notes, the Guarantees and the Registration 
Rights Agreement conform in all material respects as to legal matters to 
their respective descriptions contained under the caption "Description of the 
Notes."

     J.   The statements in the Offering Memorandum under the caption 
"Certain U.S. Federal Income Tax Considerations," insofar as such statements 
constitute matters of law or legal conclusions, are accurate in all material 
respects.

     K.   Such counsel (i) is of the opinion that each document incorporated by
reference in the Offering Memorandum (except for financial statements and
schedules and notes thereto 

                                       

                                      B-3

and other financial and statistical data included therein as to which such 
counsel need not express any opinion), complied as to form when filed with 
the Commission in all material respects with the Exchange Act and the rules 
and regulations of the Commission thereunder and (ii) has no reason to 
believe that (except for financial statements and schedules and other 
financial and statistical data as to which such counsel need not express any 
belief) the Offering Memorandum when issued contained, or as of the date such 
opinion is delivered contains, any untrue statement of a material fact or 
omitted or omits to state a material fact necessary in order to make the 
statements therein, in the light of the circumstances under which they were 
made, not misleading.

     L.   Assuming the representations and warranties of the Company, the 
Guarantors and the Placement Agents in the Placement Agreement are true, 
correct and complete and assuming compliance by the Company, the Guarantors 
and the Placement Agents with the covenants set forth in the Placement 
Agreement, it is not necessary in connection with the offer, sale and 
delivery of the Notes to the Placement Agents under the Placement Agreement 
or in connection with the initial resale of such Notes by the Placement 
Agents in accordance with the Placement Agreement to register the Notes or 
the Guarantees under the Securities Act of 1933 or to qualify the Indenture 
under the Trust Indenture Act of 1939, it being understood that no opinion is 
expressed as to any subsequent resale of any Note.

     With respect to paragraph K above, counsel may state that his or her 
opinion and belief are based upon his or her participation in the preparation 
of the Offering Memorandum (and any amendments or supplements thereto) and 
review and discussion of the contents thereof [and review of the documents 
incorporated by reference therein], but are without independent check or 
verification except with respect to paragraphs I and J.            




                                                                     EXHIBIT C

      Form of Opinion of Vice President-Legal Services and Chief Counsel of 
the Company

     The opinion of the Vice President-Legal Services and chief Counsel of 
the Company to be delivered pursuant to Section 5(d) of the Placement 
Agreement shall be to the effect that:

          (A)  After due inquiry, such counsel does not know of any legal or
     governmental proceedings pending or threatened to which the Company or any
     Guarantor is a party or to which any of the properties of the Company or
     any Guarantor is subject other than proceedings fairly summarized in all
     material respects in the Offering Memorandum and proceedings which such
     counsel believes are not likely to have a material adverse effect on
     Protection One and the Subsidiaries, taken as a whole, or on the power or
     ability of the Company or any Guarantor to perform its obligations under
     the Placement Agreement, the Indenture, the Registration Rights Agreement,
     the Notes (in the case of the Company) or the Guarantees (in the case of
     the Guarantors) or to consummate the transactions contemplated by the
     Offering Memorandum.
