Item 5. Other Events.

                 (a)      Public Offering; Shares Outstanding.  On September 20,
1996, Protection One Alarm Monitoring, Inc. ("Monitoring") completed an
underwritten public offering of $90 million aggregate principal amount of
Monitoring's 6-3/4% Convertible Senior Subordinated Notes due 2003 (the
"Convertible Notes") that was registered under the Securities Act of 1933, as
amended.  On October 11, 1996, Monitoring issued an additional $13.5 million
aggregate principal amount of Convertible Notes in connection with the exercise,
in full, of the underwriters' over-allotment option.  The net proceeds to
Monitoring of the offering, including the exercise of the over-allotment option,
were $99.6 million and were used to repay indebtedness outstanding under
Monitoring's revolving credit facility (the "Revolving Credit Facility") and for
general corporate purposes.  The Convertible Notes are listed on the New York
Stock Exchange and trade under the symbol "ALRM 03."

                 The Convertible Notes were issued pursuant to that certain
Subordinated Debt Shelf Indenture dated as of August 29, 1996, among
Monitoring, Monitoring's parent Protection One, Inc. ("POI") and State Street
Bank and Trust Company, as Trustee, as supplemented and amended by a
Supplemental Indenture No. 1 dated as of September 20, 1996 (the "Supplemental
Indenture").  A copy of the Supplemental Indenture, which sets forth the terms
and form of the Convertible Notes, is attached hereto as Exhibit 4.1.

                 The Convertible Notes are fully and unconditionally guaranteed
by POI and are convertible into shares of the Common Stock, par value $.01 per
share ("Common Stock"), of POI at an initial price of $17.95 per share.  At
October 16, 1996, there were 13,466,671 shares of Common Stock outstanding.

                 (b)      Amendment of Credit Agreement.  In connection with the
public offering of the Convertible Notes, the credit agreement governing the
Revolving Credit Facility was amended pursuant to the Consent and First
Amendment to Amended and Restated Credit Agreement dated September 16, 1996
among Monitoring, Heller Financial Inc. as Agent and lender and the other
lenders signatory thereto.  A copy of said Consent and First Amendment is
attached as Exhibit 10.1 to this Current Report.

                 (c)      PacifiCorp Agreement.  On October 11, 1996, Monitoring
and PacifiCorp, a Portland-based utility ("PacifiCorp"), entered into an
agreement (the "PacifiCorp Agreement") pursuant to which Monitoring will offer
security alarm systems and monitoring services under a Protection One/PacifiCorp
"co-brand" (the "Co-Branded Program") to PacifiCorp's residential and small
business customers in PacifiCorp's service territories in the western United
States.  Prospective subscribers generated through the Co-Branded Program's
marketing efforts, which may include television, radio and print advertising
displaying the co-brand, will be referred to participants in Monitoring' dealer
program, and Monitoring will purchase, subject to its customary due diligence,
the monitoring contracts obtained by the dealers in connection with the sale and
installation of the co-branded alarm system. Under the terms of the PacifiCorp
Agreement, Monitoring will remit to PacifiCorp a percentage of the monthly
recurring revenue from the subscriber accounts created in connection with the
use of PacifiCorp's trademarks, trade names and logos.

                 (d)      Cautionary Statement.  In connection with the "safe
harbor" provisions of the Private Securities Litigation Reform Act of 1995, POI

                                  ARTICLE TWO

                              The Series of Notes

                 SECTION 2.01  Title of the Securities.

                 There shall be a series of Securities designated the "6 3/4%
Convertible Senior Subordinated Notes due 2003" (the "Notes").

                 SECTION 2.02  Limitation on Aggregate Principal Amount; Dates
of Notes.

                  The aggregate principal amount of the Notes shall be limited
to $90,000,000 (or $103,500,000 if the over-allotment option set forth in
Section 3 of the Underwriting Agreement dated September 16, 1996 (as amended
from time to time by the parties thereto) by and between the Issuer and the
Parent Company and Morgan Stanley & Co. Incorporated, Bear, Stearns & Co. Inc.
and Montgomery Securities is exercised in full) and, except as provided in this
Section and in Section 2.09 of the Subordinated Indenture, the Issuer shall not
execute and the Trustee shall not authenticate or deliver Notes in excess of
such aggregate principal amount.

                 Nothing contained in this Section 2.02 or elsewhere in this
Supplemental Indenture, or in the Notes, is intended to or shall limit
execution by the Issuer or authentication or delivery by the Trustee of Notes
under the circumstances contemplated by Sections 2.04, 2.05, 2.07, 2.09, 2.11,
8.05 and 11.02 of the Subordinated Indenture and Sections 3.03, 3.05 and 4.02
of this Supplemental Indenture.

                 SECTION 2.03  Form and Denomination of Notes.  The Notes and
the Trustee's certificate of authentication to be borne by such Notes shall be
substantially in the form set forth in Exhibit A, which is incorporated in and
made a part of this Supplemental Indenture.  It shall not be necessary for any
Guarantor to execute any Notes.





<PAGE>   15
                                       11

                 Any of the Notes may have such letters, numbers or other marks
of identification and such notations, legends and endorsements as the officers
executing the same may approve (execution thereof to be conclusive evidence of
such approval) and as are not inconsistent with the provisions of this
Indenture, or as may be required to comply with any law or with any rule or
regulation made pursuant thereto or with any rule or regulation of any
securities exchange or automated quotation system on which the Notes may be
listed, or to conform to usage.

                 The terms and provisions contained in the form of Note
attached as Exhibit A hereto shall constitute, and are hereby expressly made, a
part of this Indenture and, to the extent applicable, the Issuer and the
Trustee, by their execution and delivery of this Indenture, expressly agree to
such terms and provisions and to be bound thereby.

                 The Notes shall be issuable and transferable in fully
registered form as Registered Securities, without coupons, in denominations of
$1,000 principal amount and integral multiples thereof.  The Notes shall
initially be issued in the form of one or more Registered Global Securities
deposited with the Trustee, as custodian for the Depositary.  The Depositary
may surrender a Registered Global Security in whole or in part for Notes in
definitive registered form without coupons in the manner provided by Section
2.08 of the Subordinated Indenture.  The Person designated as Depositary with
respect to the Notes is The Depository Trust Company, its nominees and their
respective successors.

                 SECTION 2.04  Date of Notes; Payments of Interest.  Every Note
shall be dated the date of its authentication and shall bear interest from the
applicable date in each case as specified on the face of the form of Note
attached as Exhibit A hereto.  Interest on the Notes shall be computed on the
basis of a 360-day year comprised of twelve 30-day months.

                 The person in whose name any Note (or its Predecessor Note) is
registered on the Note register at the close of business on any record date
with respect to any interest payment date shall be entitled to receive the
interest payable on such interest payment date, except (i) that the interest
payable upon redemption (unless the date of redemption is an interest payment
date) will be payable to the person to whom principal is payable and (ii) as
set forth in the next succeeding sentence.  In the case of any Note (or portion
thereof) which is converted into Common Stock of the Parent Company during the
period from (but excluding) a record date to (but excluding) the next
succeeding interest payment date either (i) if such Note (or portion thereof)
has been called for redemption on a redemption date which occurs during such
period, or is to be redeemed in connection with a Fundamental Change on a
Repurchase Date (as defined in Section 3.05) which occurs during such period,
the Issuer shall not be required to pay interest on such interest payment date
in respect of any such Note (or portion thereof) except to the extent required
to be paid upon redemption of such Note or portion thereof pursuant to Section
3.03 or 3.05 hereof or (ii) if otherwise, any Note (or portion thereof)
submitted for conversion during such period shall be accompanied by funds equal
to the interest payable on such succeeding interest payment date on the
principal amount so converted.  The term "record date" with respect to any
interest payment date shall mean the March 1 or September 1 preceding said
March 15 or September 15, respectively.





<PAGE>   16
                                       12

                 Any interest on any Note which is payable, but is not
punctually paid or duly provided for, on any said March 15 or September 15
(herein called "Defaulted Interest") shall forthwith cease to be payable to the
Noteholder on the relevant record date by virtue of such Holder having been
such Noteholder; and such Defaulted Interest shall be paid by the Issuer, at
its election in each case, as provided in clause (1) or (2) below:

                 (1)      The Issuer may elect to make payment of any Defaulted
         Interest to the Persons in whose names the Notes (or their respective
         Predecessor Notes) are registered at the close of business on a
         special record date for the payment of such Defaulted Interest, which
         shall be fixed in the following manner.  The Issuer shall notify the
         Trustee in writing of the amount of Defaulted Interest to be paid on
         each Note and the date of the payment (which shall be not less than
         twenty-five (25) days after the receipt by the Trustee of such notice,
         unless the Trustee shall consent to an earlier date), and at the same
         time the Issuer shall deposit with the Trustee an amount of money
         equal to the aggregate amount to be paid in respect of such Defaulted
         Interest or shall make arrangements satisfactory to the Trustee for
         such deposit prior to the date of the proposed payment, such money
         when deposited to be held in trust for the benefit of the Persons
         entitled to such Defaulted Interest as in this clause provided.
         Thereupon the Trustee shall fix a special record date for the payment
         of such Defaulted Interest which shall be not more than fifteen (15)
         days and not less than ten (10) days prior to the date of the proposed
         payment and not less than ten (10) days after the receipt by the
         Trustee of the notice of the proposed payment.  The Trustee shall
         promptly notify the Issuer of such special record date and, in the
         name and at the expense of the Issuer, shall cause notice of the
         proposed payment of such Defaulted Interest and the special record
         date therefor to be mailed, first-class postage prepaid, to each
         Noteholder at such Noteholder's address as it appears in the Note
         register, not less than ten (10) days prior to such special record
         date.  Notice of the proposed payment of such Defaulted Interest and
         the special record date therefor having been so mailed, such Defaulted
         Interest shall be paid to the Persons in whose names the Notes (or
         their respective Predecessor Notes) were registered at the close of
         business on such special record date and shall no longer be payable
         pursuant to the following clause (2).

                 (2)      The Issuer may make payment of any Defaulted Interest
         in any other lawful manner not inconsistent with the requirements of
         any securities exchange or automated quotation system on which the
         Notes may be listed or designated for issuance, and upon such notice
         as may be required by such exchange or automated quotation system, if,
         after notice given by the Issuer to the Trustee of the proposed
         payment pursuant to this clause, such manner of payment shall be
         deemed practicable by the Trustee.

                 SECTION 2.05  Place of Payment.

                 An office or agency of the Issuer where the Notes may be
presented or surrendered for payment, where the Notes may be surrendered for
registration of transfer or exchange and where notices and demands to and upon
the Issuer in respect of the Notes and the Subordinated Indenture may be served
shall be maintained in the Borough of Manhattan, The





<PAGE>   17
                                       13

City of New York, New York, and the office or agency maintained by the Issuer
for such purpose shall initially be c/o State Street Bank and Trust Company, 61
Broadway, Concourse Level, New York, New York 10006.

                 SECTION 2.06  Method of Payment.

                 Payment of the principal of and interest on the Notes will be
made at the office or agency of the Issuer maintained for that purpose in the
Borough of Manhattan, The City of New York (which shall initially be the
Corporate Trust Office of the Trustee specified in the Subordinated Indenture)
by 10:00 a.m., New York City time, on the date due, in Dollars.  At the option
of the Issuer, payments of principal and interest on the Notes may be made (i)
by check mailed to the address of the Person entitled thereto as such address
shall appear in the register of Holders of the Notes or (ii) by wire transfer
to an account maintained by the Person entitled thereto located in the United
States as specified in the register of Holders of the Notes; provided, however,
that payments to the Depositary shall be made by wire transfer of immediately
available funds to the account of the Depositary or its nominee.

                 SECTION 2.07  Registrar and Paying Agent.

                 The Trustee shall initially serve as registrar and paying
agent for the Notes.  If, at any time, the Trustee is not the registrar for the
Notes, the registrar shall make available to the Trustee, on or before each
interest payment date and at such other times as the Trustee may reasonably
request, the names and addresses of the Noteholders as they appear in the
register of the Notes.  The Issuer may have one or more co-registrars and one
or more additional paying agents for the Notes.  Unless the context otherwise
requires, the terms "registrar" and "paying agent" shall apply to any
co-register and additional paying agent for the Notes, respectively.

                 The Issuer shall enter into an appropriate agency agreement
with any registrar or paying agent for the Notes not a party to this
Supplemental Indenture.  The agreement shall implement the provisions of this
Supplemental Indenture that relate to such registrar or paying agent.  The
Issuer shall give prompt written notice to the Trustee of the name and address
of any such registrar or paying agent and any change in the address of such
registrar or paying agent.  If the Issuer fails to maintain a registrar and/or
paying agent for the Notes and/or an agent for service of notices and demands
on the Issuer, the Trustee shall act as such registrar, paying agent and/or
agent for service of notices and demands for so long as such failure shall
continue.  The Issuer may remove any registrar or paying agent upon written
notice to such Person and the Trustee; provided that no such removal shall
become effective until (i) the acceptance of an appointment by a successor
registrar or paying agent to such registrar or paying agent, as applicable, as
evidenced by an appropriate agency agreement entered into by the Issuer and
such successor registrar or paying agent delivered to the Trustee, or (ii)
notification to the Trustee that the Trustee shall serve as such registrar or
paying agent until the appointment of a successor registrar or paying agent in
accordance with clause (i) of this proviso.  The Issuer, any Subsidiary of the
Issuer or any Affiliate of any of them may act as paying agent or registrar for
the Notes and/or agent for service of notice and demand on the Issuer;
provided, however, that neither the Issuer, any Subsidiary of the Issuer nor
any Affiliate of any of them shall act as paying agent for the Notes in
connection with the defeasance of the Securities or the discharge of this
Indenture.

                                 ARTICLE THREE

                              Redemption of Notes

                 SECTION 3.01  Redemption Prices.  The Issuer may not redeem
the Notes prior to September 19, 1999.  Subject to the provisions of Section
3.03, at any time on or after September 19, 1999, the Issuer may, at its
option, redeem all or from time to time any part of the Notes on any date prior
to maturity, upon notice as set forth in Section 3.02, and at the optional
redemption prices set forth in the form of Note attached as Exhibit A hereto,
together with accrued interest to, but excluding, the date fixed for
redemption.

                 SECTION 3.02  Notice of Redemption; Selection of Notes.  In
case the Issuer shall desire to exercise the right to redeem all or, as the
case may be, any part of the Notes pursuant to Section 3.01, it shall fix a
date for redemption and it or, at its written request received by the Trustee
not fewer than forty-five (45) days prior (or such shorter period of time as
may be acceptable to the Trustee) to the date fixed for redemption, the Trustee
in the name of the and at the expense of the Issuer, shall mail or cause to be
mailed a notice of such redemption at least 30 days prior to the date fixed for
redemption to the Holders of Notes so to be redeemed as a whole or in part at
their last addresses as the same appear on the Note register (provided, that
any such request so given by the Issuer may be revoked by the Issuer at any
time prior to the time at which the Trustee shall have given the requested
notice to the Holders of the Notes, and provided, further, that if the Issuer
shall give such notice, it shall also give written notice, and written notice
of the Notes to be redeemed, to the Trustee).  Such mailing shall be by first
class mail.  The notice if mailed in the manner herein provided shall be
conclusively presumed to have been duly given, whether or not the Holder
receives such notice.  In any case, failure to give such notice by mail or any
defect in the notice to the Holder of any Note designated for redemption as a
whole or in part shall not affect the validity of the proceedings for the
redemption of any other Note.

                 Each such notice of redemption shall specify the aggregate
principal amount of Notes to be redeemed, the date fixed for redemption (which
shall be a Business Day), the redemption price at which Notes are to be
redeemed, the place or places of payment, that payment will be made upon
presentation and surrender of such Notes, that interest accrued to the date
fixed for redemption will be paid as specified in said notice, and that on and
after such date, interest thereon or on the portion thereof to be redeemed will
cease to accrue.  Such notice shall also state the current Conversion Price and
the date on which the right to convert such Notes or portions thereof into
Common Stock of the Parent Company will expire.  If fewer than all the Notes
are to be redeemed, the notice of redemption shall identify the Notes to be
redeemed.  In case any Note is to be redeemed in part only, the notice of
redemption shall state the portion of the principal amount thereof to be
redeemed and shall state that on and after the date fixed for redemption, upon
surrender of such Note, a new Note or Notes in principal amount equal to the
unredeemed portion thereof will be issued.

                 On or prior to the redemption date specified in the notice of
redemption given as provided in this Section 3.02, the Issuer will deposit with
the Trustee or with one or more paying





<PAGE>   19
                                       15

agents (or, if the Issuer is acting as its own paying agent, set aside,
segregate and hold in trust as provided in Section 3.04 of the Subordinated
Indenture) an amount of money sufficient to redeem on the redemption date all
the Notes (or portions thereof) so called for redemption (other than those
theretofore surrendered for conversion into Common Stock of the Parent Company
and those that prior to such date have been delivered by the Issuer to the
Trustee for cancellation) at the appropriate redemption price, together with
accrued interest to, but excluding, the date fixed for redemption; provided
that if such payment is made on the redemption date it must be received by the
Trustee or paying agent, as the case may be, by 10:00 a.m., New York City time,
on such date.  If any Note called for redemption is converted pursuant hereto,
any money deposited with the Trustee or any paying agent or so segregated and
held in trust for the redemption of such Note shall be paid to the Issuer upon
its written request, or, if then held by the Issuer shall be discharged from
such trust.  Whenever any Notes are to be redeemed, the Issuer will give the
Trustee written notice in the form of an Officers' Certificate not fewer than
forty-five (45) days (or such shorter period of time as may be acceptable to
the Trustee), or if the Issuer is mailing the notice of redemption relating to
such redemption, not fewer than thirty (30) days (or such shorter period of
time as may be acceptable to the Trustee), prior to the redemption date as to
the aggregate principal amount of Notes to be redeemed.

                 If fewer than all the Notes are to be redeemed, the Trustee
shall select the Notes to be redeemed (in principal amounts of $1,000 or
integral multiples thereof) in compliance with the requirements, as certified
to the Trustee by the Issuer in the form of an Officers' Certificate, of the
principal national securities exchange on which the Notes are listed, or if the
Notes are not so listed, by lot or, in the Trustee's discretion, on a pro rata
basis or by another method the Trustee considers fair and appropriate.  If any
Note selected for partial redemption is converted in part after such selection,
the converted portion of such Note shall be deemed (so far as may be) to be the
portion to be selected for redemption.  The Notes (or portions thereof) so
selected shall be deemed duly selected for redemption for all purposes hereof,
notwithstanding that any such Note is converted as a whole or in part before
the mailing of the notice of redemption.  The Trustee shall notify the Issuer
and the registrar of the Notes promptly in writing of the Notes or portions of
Notes to be called for redemption.

                 Upon any redemption of less than all Notes, the Issuer and the
Trustee may (but need not) treat as outstanding any Notes surrendered for
conversion during the period of fifteen (15) days next preceding the mailing of
a notice of redemption and may (but need not) treat as outstanding any Note
authenticated and delivered during such period in exchange for the unconverted
portion of any Note converted in part during such period.

                 SECTION 3.03  Payment of Notes Called for Redemption.  If
notice of redemption has been given as above provided, the Notes or portion of
Notes with respect to which such notice has been given shall, unless converted
into Common Stock of the Parent Company pursuant to the terms hereof, become
due and payable on the date fixed for redemption and at the place or places
stated in such notice at the applicable redemption price, together with
interest accrued to (but excluding) the date fixed for redemption, and on and
after said date (unless the Issuer shall default in the payment of such Notes
at the redemption price, together with interest accrued to said date) interest
on the Notes or portion of Notes so called for redemption shall cease to accrue
and such Notes shall cease after the close of business on the





<PAGE>   20
                                       16

Business Day next preceding the date fixed for redemption to be convertible
into Common Stock of the Parent Company and, except as provided in Sections
6.05 and 10.04 of the Subordinated Indenture, to be entitled to any benefit or
security under this Indenture, and the Holders thereof shall have no right in
respect of such Notes except the right to receive the redemption price thereof
and unpaid interest to (but excluding) the date fixed for redemption.  On
presentation and surrender of such Notes at a place of payment in said notice
specified, the said Notes or the specified portions thereof shall be paid and
redeemed by the Issuer at the applicable redemption price, together with
interest accrued thereon to (but excluding) the date fixed for redemption;
provided that, if the applicable redemption date is an interest payment date,
the semi-annual payment of interest becoming due on such date shall be payable
to the Holders of such Notes registered as such on the relevant record date
instead of the Holders surrendering such Notes for redemption on such date.

                 Upon presentation of any Note redeemed in part only, the
Issuer shall execute and the Trustee shall authenticate and deliver to the
Holder thereof, at the expense of the Issuer, a new Note or Notes, of
authorized denominations, in principal amount equal to the unredeemed portion
of the Notes so presented.

                 Notwithstanding the foregoing, neither the Issuer nor the
Trustee shall redeem any Notes or mail any notice of optional redemption (i)
during the continuance of a Default in payment of interest on the Notes or if
accrued interest on any Notes for any interest payment period terminating on or
prior to the last interest payment date before the date of redemption otherwise
remains unpaid or (ii) during the continuance of any Event of Default, provided
that for purposes of this clause (ii), the Trustee shall not redeem any Notes
or mail any notice of optional redemption during the continuance of any Event
of Default (other than an Event of Default under Sections 5.01(a) or 5.01(b) of
the Subordinated Indenture) of which a Responsible Officer of the Trustee has
knowledge.  If any Note called for redemption shall not be so paid upon
surrender thereof for redemption, the principal shall, until paid or duly
provided for, bear interest from the date fixed for redemption at the rate
borne by the Note and such Note shall remain convertible into Common Stock of
the Parent Company until the principal shall have been paid or duly provided
for.

                 SECTION 3.04  Conversion Arrangement on Call for Redemption.
In connection with any redemption of Notes, the Issuer may arrange for the
purchase and conversion of any Notes by an agreement with one or more
investment bankers or other purchasers to purchase such Notes by paying to the
Trustee in trust for the Noteholders, on or before the date fixed for
redemption, an amount not less than the applicable redemption price, together
with interest accrued to (but excluding) the date fixed for redemption, of such
Notes.  Notwithstanding anything to the contrary contained in this Article
Three, the obligation of the Issuer to pay the redemption price of such Notes,
together with interest accrued to (but  excluding) the date fixed for
redemption, shall be deemed to be satisfied and discharged to the extent such
amount is so paid by such purchasers.  If such an agreement is entered into, a
copy of which will be filed with the Trustee prior to the date fixed for
redemption, any Notes not duly surrendered for conversion by the Holders
thereof may, at the option of the Issuer, be deemed, to the fullest extent
permitted by law, acquired by such purchasers from such Holders and
(notwithstanding anything to the contrary contained in Article Four)
surrendered by such purchasers for conversion, all as





<PAGE>   21
                                       17

of immediately prior to the close of business on the date fixed for redemption
(and the right to convert any such Notes shall be extended through such time),
subject to payment of the above amount as aforesaid.  At the written direction
of the Issuer, the Trustee shall hold and dispose of any such amount paid to it
in the same manner as it would monies deposited with it by the Issuer for the
redemption of Notes.  Without the Trustee's prior written consent, no
arrangement between the Issuer and such purchasers for the purchase and
conversion of any Notes shall increase or otherwise affect any of the powers,
duties, responsibilities or obligations of the Trustee as set forth in this
Indenture.

                 SECTION 3.05  Redemption at Option of Holders.

                 (a)      If, at any time prior to September 15, 2003, there
shall occur a Fundamental Change, then each Noteholder shall have the right, at
such Holder's option, to require the Issuer to redeem all of such Holder's
Notes, or any portion thereof that is an integral multiple of $1,000 principal
amount, on the date (the "Repurchase Date") that is 30 days after the date of
the Issuer Notice (as defined in Section 3.05(b) below) of such Fundamental
Change (or, if such 30th day is not a Business Day, the next succeeding
Business Day).  Such repayment shall be made at the following prices (expressed
as percentages of the principal amount) in the event of a Repurchase Date
occurring during the 12-month period beginning September 15:

and 100% at September 15, 2003; provided that if the Applicable Price with
respect to the Fundamental Change is less than the Reference Market Price, the
Issuer shall redeem such Notes at a price equal to the foregoing redemption
price multiplied by the fraction obtained by dividing the Applicable Price by
the Reference Market Price; provided further, that if such repayment date is
March 15 or September 15, then the interest payable on such date shall be paid
to the Holder of record of the Note on the next preceding March 1 or September
1.  In each case, the Issuer shall also pay to such Holders accrued interest
to, but excluding, the Repurchase Date on the redeemed Notes.

                 Upon presentation of any Note redeemed in part only, the
Issuer shall execute and, upon the Issuer's written direction to the Trustee,
the Trustee shall authenticate and deliver to the Holder thereof, at the
expense of the Issuer, a new Note or Notes, of authorized denominations, in
principal amount equal to the unredeemed portion of the Notes so presented.

                 (b)      On or before the tenth day after the occurrence of a
Fundamental Change, the Issuer, or, at its written request (which must be
received by the Trustee at least five Business Days prior to the date the
Trustee is requested to give notice as described below), the Trustee in the
name of and at the expense of the Issuer, shall mail or cause to be mailed to
all Holders of





<PAGE>   22
                                       18

record on the date of the Fundamental Change a notice (the "Issuer Notice") of
the occurrence of such Fundamental Change and of the redemption right at the
option of the Holders arising as a result thereof.  Such notice shall be mailed
in the manner and with the effect set forth in the first paragraph of Section
3.02.  The Issuer shall also deliver a copy of the Issuer Notice to the Trustee
at such time as it is mailed to Noteholders and shall issue for distribution to
Bloomberg Business News, Dow Jones & Company, Inc. and to Reuters Economic
Services a press release announcing the occurrence of such Fundamental Change
and of the redemption right arising as a result thereof.

                 Each Issuer Notice shall specify the circumstances
constituting the Fundamental Change, the Repurchase Date, the price at which
the Issuer shall be obligated to redeem Notes, the latest time on the
Repurchase Date by which the Holder must exercise the redemption right (the
"Fundamental Change Expiration Time"), that the Holder shall have the right to
withdraw any Notes surrendered prior to the Fundamental Change Expiration Time,
a description of the procedure which a Noteholder must follow to exercise such
redemption right and to withdraw any surrendered Notes, the place or places
where the Holder is to surrender such Holder's Notes, and the amount of
interest accrued on each Note to the Repurchase Date.

                 No failure of the Issuer to give the foregoing notices and no
defect therein shall limit the Noteholders' redemption rights or affect the
validity of the proceedings for the repurchase of the Notes pursuant to this
Section 3.05.

                 (c)      For a Note to be so repaid at the option of the
Holder, the Issuer must receive at the office or agency of the Issuer
maintained for that purpose or, at the option of such Holder, the Corporate
Trust Office, such Note with the form entitled "Option to Elect Repayment Upon
A Fundamental Change" on the reverse thereof duly completed, together with such
Notes duly endorsed for transfer, on or before the Fundamental Change
Expiration Time.  All questions as to the validity, eligibility (including time
of receipt) and acceptance of any Note for repayment shall be determined by the
Issuer, whose determination shall be final and binding absent manifest error.

                 (d)      On or prior to the Repurchase Date, the Issuer will
deposit with the Trustee or with one or more paying agents (or, if the Issuer
is acting as its own paying agent, set aside, segregate and hold in trust as
provided in Section 3.04 of the Subordinated Indenture) an amount of money
sufficient to repay on the Repurchase Date all the Notes to be repaid on such
date at the appropriate redemption price, together with accrued interest to
(but excluding) the Repurchase Date; provided that if such payment is made on
the Repurchase Date it must be received by the Trustee or paying agent, as the
case may be, by 10:00 a.m., New York City time, on such date.  Payment for
Notes surrendered for redemption (and not withdrawn) prior to the Fundamental
Change Expiration Time will be made promptly (but in no event more than five
Business Days) following the Repurchase Date by mailing checks for the amount
payable to the Holders of such Notes entitled thereto as they shall appear on
the registry books of the Issuer.

                 (e)      In the case of a consolidation, merger, conveyance,
transfer or lease to which Section 4.06 applies, in which the Common Stock of
the Parent Company is changed or exchanged as a result into the right to
receive securities, cash or other property which includes





<PAGE>   23
                                       19

shares of Common Stock of the Parent Company or another person that are, or
upon issuance will be, traded on a United States national securities exchange
or approved for trading on an established automated over-the-counter trading
market in the United States and such shares constitute at the time such change
or exchange becomes effective in excess of 50% of the aggregate fair market
value of such securities, cash and other property (as determined by the Issuer,
which determination shall be conclusive and binding), then the Person formed by
such consolidation or resulting from such merger or which acquires such assets,
as the case may be, shall execute and deliver to the Trustee a supplemental
indenture (accompanied by an  Opinion of Counsel that such supplemental
indenture complies with the Trust Indenture Act as in force at the date of
execution of such supplemental indenture) modifying the provisions of this
Indenture relating to the right of Holders of the Notes to cause the Issuer to
repurchase the Notes following a Fundamental Change, including without
limitation the applicable provisions of this Section 3.05 and the definitions
of the Applicable Price, Common Stock, Fundamental Change and Reference Market
Price, as appropriate, as determined in good faith by the Issuer (which
determination shall be conclusive and binding), to make such provisions apply
to the Common Stock and the issuer thereof if different from the Parent Company
and Common Stock of the Parent Company (in lieu of the Parent Company and the
Common Stock of the Parent Company).

                 (f)      Upon receipt by the Corporation Trust Office or the
office or agency of the Issuer referred to in Section 3.05(c) above of a Note
for repayment pursuant to Section 3.05(c), the Holder of such Note shall
(unless such Note is withdrawn as specified in the following paragraph)
thereafter be entitled to receive solely the amount specified in Section
3.05(a) with respect to such Note.  Notes surrendered for repayment as provided
in Section 3.05(c) may not be converted pursuant to Article Four on or after
the date of the delivery of such Note unless such Note has been validly
withdrawn as specified in the following paragraph.

                 A Note surrendered pursuant to Section 3.05(c) may be
withdrawn by means of a written notice of withdrawal delivered to the office or
agency to which the Note was surrendered at any time prior to the Fundamental
Change Expiration Time specifying the certificate number or numbers, and the
principal amount, of the Note or Notes in respect of which such notice or
withdrawal is being submitted and the principal amount, if any, of Notes that
remain subject to the original surrender for repayment.

                                  ARTICLE FOUR

                              Conversion of Notes

                 SECTION 4.01  Right to Convert.  Subject to and upon
compliance with the provisions of this Supplemental Indenture and the
Subordinated Indenture, including, without limitation, Articles Six and Seven
of this Supplemental Indenture, the Holder of any Note shall have the right, at
such Holder's option, at any time after ninety (90) days following the latest
date of original issuance of the Notes and prior to the close of business on
September 15, 2003 (except as provided in Section 3.05(f) and except that, with
respect to any Note or portion of a Note which shall be called for redemption
such right shall terminate, except as provided in Section 3.04 or Section 4.02,
at the close of business on the Business Day next preceding the date fixed for
redemption of such Note or portion of a Note unless the Issuer shall default in





<PAGE>   24
                                       20

payment due upon redemption thereof) to convert the principal amount of any
such Note, or any portion of such principal amount which is $1,000 or an
integral multiple thereof, into that number of fully paid and non-assessable
shares of Common Stock (as such shares shall then be constituted) of the Parent
Company obtained by dividing the principal amount of the Notes or portion
thereof surrendered for conversion by the Conversion Price in effect at such
time, by surrender of the Note so to be converted in whole or in part in the
manner provided, together with any required funds, in Section 4.02.  A Holder
of Notes is not entitled to any rights of a holder of Common Stock of the
Parent Company until such Holder has converted such Holder's Notes to Common
Stock of the Parent Company, and only to the extent such Notes are deemed to
have been converted to Common Stock of the Parent Company under this Article
Four.

                 SECTION 4.02  Exercise of Conversion Privilege; Issuance of
Common Stock on Conversion; No Adjustment for Interest or Dividends.  In order
to exercise the conversion privilege with respect to any Note in certificated
form, the Holder of any such Note to be converted in whole or in part shall
surrender such Note, duly endorsed, at the Parent Company Office (as defined in
Section 5.01) accompanied by the funds, if any required by the penultimate
paragraph of this Section 4.02 and shall give written notice of conversion in
the form provided on the Notes (or such other notice which is acceptable to the
Issuer and the Parent Company) to the office or agency that the Holder elects
to convert such Note or the portion thereof specified in said notice.  Such
notice shall also state the name or names (with address or addresses) in which
the certificate or certificates for shares of Common Stock of the Parent
Company which shall be issuable on such conversion shall be issued, and shall
be accompanied by transfer taxes, if required pursuant to Section 4.07.  Each
such Note surrendered for conversion shall, unless the shares issuable on
conversion are to be issued in the same name as the registration of such Note,
be duly endorsed by, or be accompanied by instruments of transfer in form
satisfactory to the Parent Company duly executed by, the Holder or such
Holder's duly authorized attorney.

                 In order to exercise the conversion privilege with respect to
any interest in a Note in global form, the beneficial holder must complete the
appropriate instruction form for conversion pursuant to the Depository's
book-entry conversion program, deliver by book-entry





<PAGE>   25
                                       21

delivery an interest in such Note in global form, furnish appropriate
endorsements and transfer documents if required by the Issuer, the Parent
Company or the Trustee or conversion agent and pay the funds, if any required
by this Section 4.02 and any transfer taxes if required pursuant to Section
4.07.

                 As promptly as practicable after satisfaction of the
requirements for conversion set forth above, subject to compliance with any
restrictions on transfer if shares issuable on conversion are to be issued in a
name other than that of the Noteholder (as if such transfer were a transfer of
the Note or Notes (or portion thereof) so converted), the Parent Company shall
issue and shall deliver to such Holder, at the Parent Company Office, a
certificate or certificates for the number of full shares of Common Stock of
the Parent Company issuable upon the conversion of such Note or portion thereof
in accordance with the provisions of this Article and a check or cash in
respect to any fractional interest in respect of a share of Common Stock of the
Parent Company arising upon such conversion, as provided in Section 4.03.  In
case any Note of a denomination greater than $1,000 shall be surrendered for
partial conversion, and subject to Section 2.03, the Issuer shall execute and
the Trustee shall authenticate and deliver to the Holder of the Note so
surrendered, without charge to such Holder, a new Note or Notes in authorized
denominations in an aggregate principal amount equal to the unconverted portion
of the surrendered Note.

                 Each conversion shall be deemed to have been affected as to
any such Note (or portion thereof) on the date on which the requirements set
forth above in this Section 4.02 have been satisfied as to such Note (or
portion thereof), and the Person in whose name any certificate or certificates
for shares of Common Stock of the Parent Company shall be issued upon such
conversion shall be deemed to have become on said date the holder or record of
the shares represented thereby; provided, however, that any such surrender on
any date when the stock transfer books of the Parent Company shall be closed
shall constitute the Person in whose name the certificates are to be issued as
the record holder thereof for all purposes on the next succeeding day on which
such stock transfer books are open, but such conversion shall be at the
Conversion Price in effect on the date upon which such Note shall be
surrendered.

                 Any Note or portion thereof surrendered for conversion during
the period from the close of business on the record date for any interest
payment date to the close of business on the Business Day next preceding the
following interest payment date shall (unless such Note or portion thereof
being converted shall have been called for redemption on a redemption date
which occurs during the period from the close of business on such record date
to the close of business on the Business Day next preceding the following
interest payment date) be accompanied by payment, in New York Clearing House
funds or other funds acceptable to the Parent Company, of an amount equal to
the interest otherwise payable on such interest payment date on the principal
amount being converted; provided, however, that no such payment need be made if
there shall exist at the time of conversion a Default in the payment of
interest on the Notes.  Except as provided above in this Section 4.02, no
payment or other adjustment shall be made for interest accrued on any Note
converted or for dividends or other distributions on any shares issued upon the
conversion on such Note as provided in this Article.





<PAGE>   26
                                       22

                 Upon the conversion of an interest in a Note in global form,
the Trustee (or other conversion agent appointed by the Parent Company) shall
make a notation on such Note in global form as to the reduction in the
principal amount represented thereby.   The Parent Company shall notify the
Trustee in writing of any conversion of Notes effected through any conversion
agent other than the Trustee.

                 SECTION 4.03  Cash Payments in Lieu of Fractional Shares.  No
fractional shares of Common Stock or scrip representing fractional shares shall
be issued upon conversion of Notes.  If more than one Note shall be surrendered
for conversion at one time by the same Holder, the number of full shares which
shall be issuable upon conversion shall be computed on the basis of the
aggregate principal amount of the Notes (or specified portions thereof to the
extent permitted hereby) so surrendered.  If any fractional share of stock
would be issuable upon the conversion of any Note or Notes, the Parent Company
shall make an adjustment any payment therefor in cash at the current market
value thereof to the Holder of Notes.  The current market value of a share of
Common Stock shall be the Closing Price on the first Business Day immediately
preceding the day on which the Notes (or specified portions thereof) are deemed
to have been converted.

                 SECTION 4.04  Conversion Price.  The conversion price shall be
as specified in the form of Note (herein called the "Conversion Price")
attached as Exhibit A hereto, subject to adjustment as provided in this Article
Four.

                 SECTION 4.05  Adjustment of Conversion Price.  The Conversion
Price shall be adjusted from time to time by the Issuer as follows:

                          (a)     In case the Parent Company shall hereafter
         pay a dividend or make a distribution to all holders of its
         outstanding Common Stock in shares of Common Stock of the Parent
         Company, the Conversion Price in effect at the opening of business on
         the date following the date fixed for the determination of
         stockholders entitled to receive such dividend or other distribution
         shall reduced by multiplying such Conversion Price by a fraction of
         which the numerator shall be the number of shares of Common Stock of
         the Parent Company outstanding at the close of business on the date
         fixed for such determination and the denominator shall be the sum of
         such number of shares and the total number of shares constituting such
         dividend or other distribution, such reduction to become effective
         immediately after the opening of business on the day following the
         date fixed for such determination.  If any dividend or distribution of
         the type described in this Section 4.05(a) is declared but not so paid
         or made, the Conversion Price shall again be adjusted to the
         Conversion Price which would then be in effect if such dividend or
         distribution had not been declared.

                          (b)     In case the Parent Company shall issue rights
         or warrants to all holders of its outstanding shares of its Common
         Stock entitling them (for a period expiring within 45 days after the
         date fixed for determination of stockholder entitled to receive such
         rights or warrants) to subscribe for or purchase shares of Common
         Stock of the Parent Company at a price per share less than the Current
         Market Price (as defined below) on the date fixed for determination of
         stockholders entitled to receive such rights





<PAGE>   27
                                       23

         or warrants, the Conversion Price shall be adjusted so that the same
         shall equal the price determined by multiplying the Conversion Price
         in effect immediately prior to the date fixed for determination of
         stockholders entitled to receive such rights or warrants by a fraction
         of which the numerator shall be the number of shares of Common Stock
         of the Parent Company outstanding at the close of business on the date
         fixed for determination of stockholders entitled to receive such
         rights and warrants plus the number of shares which the aggregate
         offering price of the total number of shares so offered would purchase
         at such Current Market Price, and of which the denominator shall be
         the number of shares of Common Stock of the Parent Company outstanding
         on the date fixed for determination of stockholders entitled to
         receive such rights and warrants plus the total number of additional
         shares of Common Stock offered for subscription or purchase.  Such
         adjustment shall be successively made whenever any such rights and
         warrants are issued, and shall become effective immediately after the
         opening of business on the day following the date fixed for
         determination of stockholders entitled to receive such rights or
         warrants.  To the extent that shares of Common Stock of the Parent
         Company issuable upon exercise of such rights or warrants are not
         delivered prior to the expiration of such rights or warrants, the
         Conversion Price shall be readjusted to the Conversion Price which
         would then be in effect had the adjustments made upon the issuance of
         such rights or warrants been made on the basis of delivery of only the
         number of shares of Common Stock of the Parent Company actually
         delivered.  In the event that such rights or warrants are not so
         issued, the Conversion Price shall again be adjusted to be the
         Conversion Price which would then be in effect if such date fixed for
         the determination of stockholders entitled to receive such rights or
         warrants had not been fixed.  In determining whether any rights or
         warrants entitle the holders to subscribe for or purchase shares of
         Common Stock of the Parent Company at less than such Current Market
         Price, and in determining the aggregate offering price of such shares
         of Common Stock, there shall be taken into account any consideration
         received by the Parent Company for such rights or warrants, the value
         of such consideration, if other than cash, to be determined by the
         Board of Directors of the Parent Company.

                          (c)     In case outstanding shares of Common Stock of
         the Parent Company shall be subdivided into a greater number of shares
         of Common Stock, the Conversion Price in effect at the opening of
         business on the day following the day upon which such subdivision
         becomes effective shall be proportionately reduced, and conversely, in
         case outstanding shares of Common Stock of the Parent Company shall be
         combined into a smaller number of shares of Common Stock, the
         Conversion Price in effect at the opening of business on the day upon
         which such combination becomes effective shall be proportionately
         increased, such reduction or increase, as the case may be, to become
         effective immediately after the opening of business on the day
         following the day upon which subdivision or combination becomes
         effective.

                          (d)     In case the Parent Company shall, by dividend
         or otherwise, distribute to all holders of its Common Stock shares of
         any class of Capital Stock of the Parent Company (other than any
         dividends or distributions to which Section 4.05(a) applies) or
         evidences of Indebtedness or assets of the Parent Company or any of
         its Subsidiaries (including securities, but excluding any rights or
         warrants referred to in





<PAGE>   28
                                       24

         Section 4.05(b), and excluding any dividend or distribution (x) paid
         exclusively in cash or (y) referred to in Section 4.05(a) (any of the
         foregoing hereinafter in this Section 4.05(d) called the "Distribution
         Securities")), then, in each such case (unless the Parent Company
         elects to reserve such Distribution Securities for distribution to the
         Noteholders upon the conversion of the Notes so that any such Holder
         converting Notes will receive upon such conversion, in addition to the
         shares of Common Stock of the Parent Company to which such Holder is
         entitled, the amount and kind of such Distribution Securities which
         such Holder would have received if such Holder had converted its Notes
         into Common Stock immediately prior to the Record Date (as defined in
         Section 4.05(i) for such distribution of the Distribution
         Securities)), the Conversion Price shall be reduced so that the same
         shall be equal to the price determined by multiplying the Conversion
         Price in effect on the Record Date with respect to such distribution
         by a fraction of which the numerator shall be the Current Market Price
         per share of the Common Stock of the Parent Company on such Record
         Date less the firm market value (as determined by the Board of
         Directors of the Parent Company, whose determination shall be
         conclusive, and described in a resolution of the Board of Directors of
         the Parent Company) on the Record Date of the portion of the
         Distribution Securities so distributed applicable to one share of
         Common Stock and the denominator shall be the Current Market Price per
         share of the Common Stock of the Parent Company, such reduction to
         become effective immediately prior to the opening of business on the
         date following such Record Date; provided, however, that in the event
         the then fair market value (as so determined) of the portion of the
         Distribution Securities so distributed applicable to one share of
         Common Stock is equal to or greater than the Current Market Price of
         the Common Stock of the Parent Company on the Record Date, in lieu of
         the foregoing adjustment, adequate provision shall be amended so that
         each Noteholder shall have the right to receive upon conversion the
         amount of Distribution Securities such Holder would have received had
         such Holder converted each Note on the Record Date.  In the event that
         such dividend or distribution is not so paid or made, the Conversion
         Price shall again be adjusted to be the Conversion Price which would
         then be in effect if such dividend or distribution had not been
         declared.  If the Board of Directors of the Parent Company determines
         the fair market value of any distribution for purposes of this Section
         4.05(d) by reference to the actual or when issued trading market for
         any securities, it must in doing so consider the prices in such market
         over the same period used in computing the Current Market Price of the
         Common Stock of the Parent Company.

                          Rights or warrants distributed by the Parent Company
         to all holders of Common Stock of the Parent Company entitling the
         holders thereof to subscribe for or purchase shares of the Parent
         Company's Capital Stock (either initially or under certain
         circumstances), which rights or warrants, until the occurrence of a
         specified event or events (a "Trigger Event"): (i) are deemed to be
         transferred with such shares of Common Stock; (ii) are not
         exercisable; and (iii) are also issued in respect of future issuances
         of Common Stock, shall be deemed not to have been distributed for
         purposed of this Section 4.05 (and no adjustment to the Conversion
         Price under this Section 4.05 will be required) until the occurrence
         of the earliest Trigger Event, whereupon such rights and warrants
         shall be deemed to have been distributed and an appropriate adjustment
         (if any is required) to the Conversion Price shall be made under this
         Section 4.05(d).  If any such

         right or warrant, including any such existing rights or warrants
         distributed prior to the date of this Supplemental Indenture, are
         subject to events, upon the occurrence of which such rights or
         warrants become exercisable to purchase different securities,
         evidences of Indebtedness or other assets, then the date of the
         occurrence of any and each such event shall be deemed to be the date
         of distribution and record date with respect to new rights or warrants
         with such rights (and a termination or expiration of the existing
         rights or warrant without exercise by any of the holders thereof.)  In
         addition, in the event of any distribution (or deemed distribution) of
         rights or warrants, or any Trigger Event or other event (of the type
         described in the preceding sentence) with respect thereto that was
         counted for purposes of calculating a distribution amount for which an
         adjustment to the Conversion Price under this Section 4.05 was made,
         (1) in that case of any such rights or warrants which shall all have
         been redeemed or repurchased without exercise by any holder thereof,
         the Conversion Price shall be readjusted upon such final redemption or
         repurchase to give effect to such distribution or Trigger Event, as
         the case may be, as though it were a cash distribution, equal to the
         per share redemption or repurchase price received by a holder or
         holders of Common Stock of the Parent Company with respect to such
         rights or warrants (assuming such holder had retained such rights or
         warrants), made to all holders of Common Stock as of the date of such
         redemption or repurchase, and (2) in the case of such rights or
         warrants which shall have expired or been terminated without exercise
         by any holders thereof, the Conversion Price shall be readjusted as if
         such rights and warrants had not been issued.

                          For purposes of this Section 4.05(d) and Section
         4.05(a) and (b), any dividend or distribution to which this Section
         4.05(d) is applicable that also includes shares of Common Stock of the
         Parent Company, or rights or warrants to subscribe for or purchase
         shares of Common Stock (or both), shall be deemed instead to be (1) a
         dividend or distribution of the evidences of Indebtedness, assets or
         shares of Capital Stock other than such shares of Common Stock or
         rights or warrants (and any Conversion Price reduction required by
         this Section 4.05(d) with respect to such dividend or distribution
         shall then be made) immediately followed by (2) a dividend or
         distribution of such shares of Common Stock or such rights or warrants
         (and any further Conversion Price reduction required by Section
         4.05(a) and (b) with respect to such dividend or distribution shall
         then be made), except (A) the Record Date of such dividend or
         distribution shall be substituted as "the date fixed for the
         determination of stockholders entitled to receive such dividend or
         other distribution" and "the date fixed for such determination" within
         the meaning of Section 4.05(a) and (b) and (B) any shares of Common
         Stock including in such dividend or distribution shall not be deemed
         "outstanding at the close of business on the date fixed for such
         determination" within the meaning of Section 4.05(a).

                          (e)     In case the Parent Company shall, by dividend
         or otherwise, distribute to all holders of its Common Stock cash
         (excluding (x) any quarterly cash dividend on the Common Stock to the
         extent the aggregate cash dividend per share of Common Stock in any
         fiscal quarter does not exceed the greater of (A) the amount per share
         of Common Stock of the next preceding quarterly cash dividend on the
         Common Stock to the extent that such preceding quarterly dividend did
         not require any adjustment of the Conversion Price pursuant to this
         Section 4.05(e) (as adjusted to reflect subdivisions





<PAGE>   30
                                       26

         or combinations of the Common Stock), and (B) 3.75% of the arithmetic
         average of the Closing Price (determined as set forth in Section
         4.05(i) during the ten Trading Days (as defined in Section 4.05(i)
         immediately prior to the date of declaration of such dividend, and (y)
         any dividend or distribution in connection with the liquidation,
         dissolution or winding up of the Parent Company, whether voluntary or
         involuntary), then, in such case, the Conversion Price shall be
         reduced so that the same shall equal the price determined by
         multiplying the Conversion Price in effect immediately prior to the
         close of business on such Record Date by a fraction of which the
         numerator shall be the Current Market Price of the Common Stock of the
         Parent Company on the Record Date less the amount of cash so
         distributed (and not excluded as provided above) applicable to one
         share of Common Stock and the denominator shall be such Current Market
         Price of the Common Stock, such reduction to be effective immediately
         prior to the opening of business on the day following the Record Date;
         provided, however, that in the event the portion of the cash so
         distributed applicable to one share of Common Stock of the Parent
         Company is equal to or greater than the Current Market Price of the
         Common Stock of the Parent Company on the Record Date, in lieu of the
         foregoing adjustment, adequate provision shall be made so that each
         Noteholder shall have the right to receive upon conversion the amount
         of cash such Holder would have received had such Holder converted each
         Note on the Record Date.  In the event that such dividend or
         distribution is not so paid or made, the Conversion Price shall again
         be adjusted to be the Conversion Price which would then be in effect
         if such dividend or distribution had not been declared.  If any
         adjustment is required to be made as set forth in this Section 4.05(e)
         as a result of a distribution that is a quarterly dividend, such
         adjustment shall be based upon the amount by which such distribution
         exceeds the amount of the quarterly cash dividend permitted to be
         excluded pursuant hereto.  If an adjustment is required to be made as
         set forth in this Section 4.05(e) above as a result of a distribution
         that is not a quarterly dividend, such adjustment shall be based upon
         the full amount of the distribution.

                          (f)     In case a tender or exchange offer made by
         the Parent Company or any Subsidiary of the Parent Company for all or
         any portion of the Common Stock of the Parent Company shall expire and
         such tender or exchange offer (as amended upon the expiration thereof)
         shall require the payment to stockholders of consideration per share
         of Common Stock of the Parent Company having a fair market value (as
         determined by the Board of Directors of the Parent Company, whose
         determination shall be conclusive and described in a resolution of the
         Board of Directors) that as of the last time (the "Expiration Time")
         tender or exchanges may be made pursuant to such tender or exchange
         offer (as it may be amended) that exceeds the Current Market Price of
         the Common Stock of the Parent Company on the Trading Day next
         succeeding the Expiration Time, the Conversion Price shall be reduced
         so that the same shall equal the price determined by multiplying the
         Conversion Price in effect immediately prior to the Expiration Time by
         a fraction of which the numerator shall be the number of shares of
         Common Stock of the Parent Company outstanding (including any tendered
         or exchange shares) on the Expiration Time multiplied by the Current
         Market Price of the Common Stock of the Parent Company on the Trading
         Day next succeeding the Expiration Time and the denominator shall be
         the sum of (x) the fair market value (determined as aforesaid) of the
         aggregate consideration payable to stockholders based on the
         acceptance (up to any





<PAGE>   31
                                       27

         maximum specified in the terms of the tender or exchange offer) of all
         shares validity tendered or exchanged and not withdrawn as of the
         Expiration Time (the shares deemed so accepted, up to any such
         maximum, being referred to as the "Purchased Shares") and (y) the
         product of the number of shares of Common Stock of the Parent Company
         outstanding (less any Purchased Shares) on the Expiration Time and the
         Current Market Price of the Common Stock of the Parent Company on the
         Trading Day next succeeding the Expiration Time, such reduction to
         become effective immediately prior to the opening of business on the
         day following the Expiration Time.  In the event that the Parent
         Company is obligated to purchase shares pursuant to any such tender or
         exchange offer, but the Parent Company is permanently prevented by
         applicable law from effecting any such purchase or all such purchases
         are rescinded, the Conversion Price shall again be adjusted to be the
         Conversion Price which would then be in effect if such tender or
         exchange offer had not been made.

                          (g)     In case of a tender or exchange offer made by
         a Person other than the Parent Company or any Subsidiary of the Parent
         Company for an amount which increases the offeror's ownership of
         Common Stock of the Parent Company to more than 25% of the Common
         Stock of the Parent Company outstanding and shall involve the payment
         by such Person of consideration per share of Common Stock having a
         fair market value (as determined by the Board of Directors of the
         Parent Company, whose determination shall be conclusive, and described
         in a resolution of the Board of Directors of the Parent Company) at
         the last time (the "Expiration Time") tenders or exchanges may be made
         pursuant to such tender or exchange offer (as it shall have been
         amended) that exceeds the Current Market Price of the Common Stock on
         the Trading Day next succeeding the Expiration Time, and in which, as
         of the Expiration Time the Board of Directors of the Parent Company is
         not recommending rejection of the offer, the Conversion Price shall be
         reduced so that the same shall equal the price determined by
         multiplying the Conversion Price in effect immediately prior to the
         Expiration Time by a fraction of which the numerator shall be the
         number of shares of Common Stock of the Parent Company outstanding
         (including any tendered or exchanged shares) on the Expiration Time
         multiplied by the Current Market Price of the Common Stock of the
         Parent Company on the Trading Day next succeeding the Expiration Time
         and the denominator shall be the sum of (x) the fair market value
         (determined as aforesaid) of the aggregate consideration payable to
         stockholders based on the acceptance (up to any maximum specified in
         the terms of the tender or exchange offer) of all shares validly
         tendered or exchanged and not withdrawn as of the Expiration Time (the
         shares deemed so accepted, up to any such maximum, being referred to
         as the "Purchased Shares") and (y) the product of the number of shares
         of Common Stock of the Parent Company outstanding (less any Purchased
         Shares) on the Expiration Time and the Current Market Price of the
         Common Stock of the Parent Company on the Trading Day next succeeding
         the Expiration Time, such reduction to become effective immediately
         prior to the opening of business on the day following the Expiration
         Time.  In the event that such Person is obligated to purchase shares
         pursuant to any such tender or exchange offer, but such Person is
         permanently prevented by applicable law from effecting any such
         purchases or all such purchases are rescinded, the Conversion Price
         shall again be adjusted to be the Conversion Price which would then be
         in effect if such tender or exchange offer had not

                                       28

         been made.  Notwithstanding the foregoing, the adjustment described in
         this Section 4.05(g) shall not be made if, as of the Expiration Time,
         the offering documents with respect to such offer disclose a plan or
         intention to cause the Parent Company to engage in any transaction
         described in Article Nine of the Subordinated Indenture.

                          (h)     In case the Parent Company shall issue Common
         Stock or securities convertible into, or exchangeable for, Common
         Stock of the Parent Company at a price per share (or having a
         conversion or exchange price per share) that is less than the then
         Current Market Price of the Common Stock of the Parent Company (but
         excluding, among other things, issuances: (a) pursuant to any bona
         fide plan for the benefit of employees, directors or consultants of
         the Parent Company or any Subsidiary of the Parent Company now or
         hereafter in effect; (b) to acquire all or any portion of a business
         in an arm's-length transaction between the Parent Company or any
         Subsidiary of the Parent Company and an unaffiliated third party
         including, if applicable, issuances upon exercise of options or
         warrants assumed in connection with such an acquisition; (c) in a bona
         fide public offering pursuant to a firm commitment underwriting (or a
         similar type of offering made pursuant to Rule 144A and/or Regulation
         S under the Securities Act) or sales at the market pursuant to a
         continuous offering stock program; (d) pursuant to the exercise of
         warrants, rights (including, without limitation, earnout rights) or
         options, or upon the conversion of convertible securities, which are
         issued and outstanding on the date hereof, or which may be issued in
         the future at fair value and with an exercise price or conversion
         price at least equal to the Current Market Price of the Common Stock
         of the Parent Company at the time of issuance of such warrant, right,
         option or convertible security; and (e) pursuant to a dividend
         reinvestment plan or other plan hereafter adopted for the reinvestment
         of dividends or interest provided that such Common Stock is issued at
         a price at least equal to 95% of the market price of the Common Stock
         at the time of such issuance), the Conversion Price shall be adjusted
         so that the Holder of each Note shall be entitled to receive, upon the
         conversion thereof, the number of shares of Common Stock of the Parent
         Company determined by multiplying (i) the Conversion Price on the day
         immediately prior to such date of issuance by (ii) a fraction, the
         numerator of which shall be the sum of (A) the number of shares of
         Common Stock of the Parent Company outstanding on such date and (B)
         the number of additional shares of Common Stock issued (or into which
         the convertible securities may convert), and the denominator of which
         shall be the sum of (1) the number of shares of Common Stock
         outstanding on such date and (2) the number of shares of Common Stock
         which the aggregate consideration receivable by the Parent Company for
         the total number of shares of Common Stock so issued (or into which
         the convertible securities may convert) would purchase at such
         Conversion Price on such date.  An adjustment made pursuant to this
         paragraph (h) shall be made on the next Business Day following the
         date on which any such issuance is made and shall be effective
         retroactively immediately after the close of business on such date.
         For purposes of this paragraph (h), the aggregate consideration
         receivable by the Parent Company in connection with the issuance of
         shares of Common Stock or of securities convertible into shares of
         Common Stock of the Parent Company shall be deemed to be equal to the
         sum of the aggregate offering price (before deduction of underwriting
         discounts or commissions and expenses payable to third parties) of all





<PAGE>   33
                                       29

         such securities plus the minimum aggregate amount, if any, payable
         upon conversion of any such convertible securities into shares of
         Common Stock of the Parent Company.

                          (i)     For purposes of this Section 4.05, the
following terms shall have the meaning indicated:

                                  (1)      "Closing Price" with respect to any
                 securities on any day shall mean the closing sale price
                 regular way on such day or, in case no such sale takes place
                 on such day, the average of the reported closing bid and asked
                 prices, regular way, in each case on the New York Stock
                 Exchange, or, if such security is not listed or admitted to
                 trading on such Exchange, on the principal national security
                 exchange or quotation system on which such security is quoted
                 or listed or admitted to trading, or, if not quoted or listed
                 or admitted to trading on any national securities exchange or
                 quotation system, the average of the closing bid and asked
                 prices of such security on the over-the-counter market on the
                 day in question as reported by the National Quotation Bureau
                 Incorporated, or a similar generally accepted reporting
                 service or if not so available, in such manner as furnished by
                 any New York Stock Exchange member firm selected from time to
                 time by the Board of Directors of the Parent Company for that
                 purpose, or a price determined in good faith by the Board of
                 Directors of the Parent Company or, to the extent permitted by
                 applicable law, a duly authorized committee thereof, whose
                 determination shall be conclusive.

                                  (2)      "Current Market Price" shall mean
                 the average of the daily Closing Prices per share of Common
                 Stock for the ten consecutive Trading Days immediately prior
                 to the date in question; provided, however, that (1) if the
                 "ex" date (as hereinafter defined) for any event (other than
                 the issuance or distribution or Fundamental Change requiring
                 such computation) that requires an adjustment to the
                 Conversion Price pursuant to Section 4.05(a), (b), (c), (d),
                 (e), (f), (g) or (h) occurs during such ten consecutive
                 Trading Days, the Closing Price for each Trading Day prior to
                 the "ex" date for such other event shall be adjusted by
                 multiplying such Closing Price by the same fraction by which
                 the Conversion Price is so required to be adjusted as a result
                 of other event, (2) if the "ex" date for any event (other than
                 the issuance, distribution or Fundamental Change requiring
                 such computation) that requires an adjustment to the
                 Conversion Price pursuant to Section 4.05(a), (b), (c), (d),
                 (e), (f), (g) or (h) occurs on or after the "ex" date for the
                 issuance or distribution requiring such computation and prior
                 to the day in question, the Closing Price for each Trading Day
                 on and after the "ex" date for such other event shall be
                 adjusted by multiplying such Closing Price by the reciprocal
                 of the fraction by which the Conversion Price is so required
                 to be adjusted as a result of such other event, and (3) if the
                 "ex" date for the issuance, distribution or Fundamental Change
                 requiring such computation is prior to the day in question,
                 after taking into account any adjustment required pursuant to
                 clause (1) or (2) of this proviso, the Closing Price for each
                 Trading Day on or after such "ex" date shall be adjusted by
                 adding thereto the amount of any cash and the fair market
                 value (as determined by the Board of Directors of the Parent
                 Company or,

                 to the extent permitted by applicable law, a duly authorized
                 committee thereof in a manner consistent with any
                 determination of such value for purposes of Section 4.05(d),
                 (f) or (g), whose determination shall be conclusive and
                 described in a resolution of the Board of Directors of the
                 Parent Company or such duly authorized committee thereof, as
                 the case may be) of the evidences of Indebtedness, shares of
                 Capital Stock or assets being distributed applicable to one
                 share of Common Stock of the Parent Company as of the close of
                 business on the day before such "ex" date.  For purposes of
                 any computation under Section 4.05(f) or (g), the Current
                 Market Price of the Common Stock of the Parent Company on any
                 date shall be deemed to be the average of the daily Closing
                 Prices per share of Common Stock for such day and the next two
                 succeeding Trading Days; provided, however, that if the "ex"
                 date for any event (other than the tender or exchange offer
                 requiring such computation) that requires an adjustment to the
                 Conversion Price pursuant to Section 4.05(a), (b), (c), (d),
                 (e), (f), (g) or (h) occurs on or after the Expiration Time
                 for the tender of exchange offer requiring such computation
                 and prior to the day in question, the Closing Price for each
                 Trading Day on and after the "ex" date for such other event
                 shall be adjusted by multiplying such Closing Price by the
                 reciprocal of the fraction by which the Conversion Price is so
                 required to be adjusted as a result of such other event.  For
                 purposes of this paragraph, the term "ex" date, (1) when used
                 with respect to any issuance or distribution, means the first
                 date on which the Common Stock of the Parent Company trades
                 regular way on the relevant exchange or in the relevant market
                 from which the Closing Price was obtained without the right to
                 receive such issuance or distribution, (2) when used with
                 respect to any subdivision or combination of shares of Common
                 Stock of the Parent Company, means the first date on which the
                 Common Stock trades regular way on such exchange or in such
                 market after the time at which such subdivision or combination
                 becomes effective, and (3) when used with respect to any
                 tender or exchange offer means the first date on which the
                 Common Stock of the Parent Company trades regular way on such
                 exchange or in such market after the Expiration Time of such
                 offer.

                                  (3)      "fair market value" shall mean the
                 amount which a willing buyer would pay a willing seller in an
                 arm's length transaction.

                                  (4)      "Record Date" shall mean, with
                 respect to any dividend, distribution or other transaction or
                 event in which the holders of Common Stock of the Parent
                 Company have the right to receive any cash, securities or
                 other property or in which the Common Stock (or other
                 applicable security) of the Parent Company is exchanged for or
                 converted into any combination of cash, securities or other
                 property, the date fixed for determination of stockholders
                 entitled to receive such cash, securities or other property
                 (whether such date is fixed by the Board of Directors of the
                 Parent Company or by statute, contract or otherwise).

                                  (5)      "Trading Day" shall mean (x) if the
                 applicable security is listed or admitted for trading on the
                 New York Stock Exchange or another national





<PAGE>   35
                                       31

                 security exchange, a day on which the New York Exchange or
                 another national security exchange is open for business or (y)
                 if the applicable security is quoted on the Nasdaq National
                 Market, a day on which trades may be made on thereon or (z) if
                 the applicable security is not so listed, admitted for trading
                 or quoted, any day other than a Saturday or Sunday or a day on
                 which banking institutions in the State of New York are
                 authorized or obligated by law or executive order to close.

                          (j)     The Issuer and the Parent Company may make
         such reductions in the Conversion Price, in addition to those required
         by Sections 4.05 (a), (b), (c), (d), (e), (f), (g) and (h) as the
         Boards of Directors of the Issuer and the Parent Company consider to
         be advisable to avoid or diminish any income tax to holders of Common
         Stock or rights to purchase Common Stock of the Parent Company
         resulting from any dividend or distribution of stock (or rights to
         acquire stock) or from any event treated as such for income tax
         purposes.

                          To the extent permitted by applicable law, the Issuer
         and the Parent Company from time to time may reduce the Conversion
         Price by any amount for any period of time if the period is at least
         twenty (20) days, the reduction is irrevocable during the period and
         the Boards of Directors of the Issuer and the Parent Company shall
         have made a determination that such reduction would be in the best
         interests of the Parent Company and its Subsidiaries taken as a whole,
         which determination shall be conclusive.  When the Conversion Price is
         reduced pursuant to the preceding sentence, the Issuer shall mail to
         Holders of record of the Notes a notice of the reduction at least
         fifteen (15) days prior to the date the reduced Conversion Price takes
         effect, and such notice shall state the reduced Conversion Price and
         the period during which it will be in effect.

                          (k)     No adjustments in the Conversion Price shall
         be required unless such adjustment would require an increase or
         decrease of at least 1% in such price; provided, however, that any
         adjustments which by reason of this Section 4.05(k) are not required
         to be made shall be carried forward and taken into account in any
         subsequent adjustment.  All calculations under this Article Four shall
         be made by the Issuer and the Parent Company, collectively, and shall
         be made to the nearest cent or to the nearest one hundredth of a
         share, as the case may be.  No adjustment need be made for rights to
         purchase Common Stock of the Parent Company pursuant to a plan of the
         Parent Company or of any of its Subsidiaries for reinvestment of
         dividends or interest.  To the extent the Notes become convertible
         into cash, assets, property or securities (other than Capital Stock of
         the Parent Company), no adjustment need be made thereafter as to the
         cash, assets, property or such securities.  Interest will not accrue
         on the cash.

                          (l)     Whenever the Conversion Price is adjusted as
         herein provided, the Issuer shall promptly file with the Trustee and
         any conversion agent other than the Trustee an Officers' Certificate
         setting forth the Conversion Price after such adjustment and setting
         forth a brief statement of the facts requiring such adjustment.
         Promptly after delivery of such certificate, the Issuer shall prepare
         a notice of such adjustment of the Conversion Price setting forth the
         adjusted Conversion Price and the date on which each





<PAGE>   36
                                       32

         adjustment becomes effective and shall mail such notice of such
         adjustments of the Conversion Price to the Holder of each Note at such
         Holder's last address appearing on the Note register, within 20 days
         after execution thereof.  Failure to deliver such notice shall not
         affect the legality or validity of any such adjustment.

                          (m)     In any case in which this Section 4.05
         provides that an adjustment shall become effective immediately after a
         record date for an event, the Parent Company may defer until the
         occurrence of such event (i) issuing to the Holder of any Note
         converted after such record date and before the occurrence of such
         event the additional shares of Common Stock of the Parent Company
         issuable upon such conversion by reason of the adjustment required by
         such event or over and above the Common Stock of the Parent Company
         issuable upon such conversion before giving effect to such adjustment
         and (ii) paying to such holder any amount in cash in lieu of any
         fraction pursuant to Section 4.03.

                          (n)     For purposes of this Section 4.05, the number
         of shares of Common Stock of the Parent Company at any time
         outstanding shall not include shares held in the treasury of the
         Parent Company but shall include shares issuable in respect of scrip
         certificates issued in lieu of fractions of shares of Common Stock of
         the Parent Company.  The Parent Company will not pay any dividend or
         make any distribution on shares of Common Stock held in the treasury
         of the Parent Company.

                 SECTION 4.06  Effect of Reclassification, Consolidation,
Merger or Sale.  If any of the following events occur, namely (i) any
reclassification or change of the outstanding shares of Common Stock of the
Parent Company (other than a subdivision or combination to which Section
4.05(c) applies), (ii) any consolidation, merger or combination of the Parent
Company with another corporation as a result of which holders of Common Stock
of the Parent Company shall be entitled to receive stock, securities or other
property or assets (including cash) with respect to or in exchange for such
Common Stock, or (iii) any sale or conveyance of the properties and assets of
the Parent Company as, or substantially as, an entirety to any other Person as
a result of which holders of Common Stock shall be entitled to receive stock,
securities or other property or assets (including cash) with respect to or in
exchange for such Common Stock, then the Parent Company or the successor or
purchasing Person, as the case may be, shall execute with the Trustee a
supplemental indenture (which shall comply with the Trust Indenture Act as in
force at the date of execution of such supplemental indenture) providing that
such Note shall be convertible into the kind and amount of shares of stock and
other securities or property or assets (including cash) receivable upon such
reclassification, change, consolidation, merger, combination, sale or
conveyance by a holder of a number of shares of Common Stock of the Parent
Company issuable upon conversion of such Notes (assuming, for such purposes, a
sufficient number of authorized shares of Common Stock of the Parent Company
available to convert all such Notes) immediately prior to such
reclassification, change, consolidation, merger, combination, sale or
conveyance assuming such holder of Common Stock did not exercise such holder's
rights of election, if any, as to the kind or amount of securities, cash or
other property receivable upon such reclassification, consolidation, merger,
combination, sale or conveyance (provided that, if the kind of amount of
securities, cash or other property receivable upon such reclassification,
change, consolidation, merger, combination, sale or conveyance is not the same





<PAGE>   37
                                       33

for each share of Common Stock of the Parent Company in respect of which such
rights of election shall not have been exercised ("nonelecting share")), then
for the purposes of this Section 4.06 the kind and amount of securities, cash
or other property receivable upon such reclassification, change, consolidation,
merger, combination, sale or conveyance for each non-electing share shall be
deemed to be the kind and amount so receivable per share by a plurality of the
non-electing shares.  Such supplemental indenture shall provide for adjustments
which shall be as nearly equivalent as may be practicable to the adjustments
provided for in this Article.

                 The Issuer shall cause notice of the execution of such
supplemental indenture to be mailed to each Holder of Notes, at such Holder's
address appearing in the Note register, within twenty (20) days after execution
thereof.  Failure to deliver such notice shall not affect the legality or
validity of such supplemental indenture.

                 The above provisions of this Section shall similarly apply to
successive reclassifications, changes, consolidations, mergers, combinations,
sales and conveyances.

                 If this Section 4.06 applies to any event or occurrence, 
Section 4.05 shall not apply.

                 SECTION 4.07  Taxes on Shares Issued.  The issue of stock
certificates on conversions of Notes shall be made without charge to the
converting Noteholder for any tax in respect of the issue thereof.  Neither the
Issuer nor the Parent Company shall, however, be required to pay any tax which
may be payable in respect of any transfer involved in the issue and delivery of
stock in any name other than that of the Holder of any Note converted, and the
Parent Company shall not be required to issue or deliver any such stock
certificate unless and until the person or persons requesting the issue thereof
shall have paid to the Parent Company the amount of such tax or shall have
established to the satisfaction of the Parent Company that such tax has been
paid.

                 SECTION 4.08  Reservation of Shares; Shares to Be Fully Paid;
Compliance with Governmental Requirements; Listing of Common Stock.  The Parent
Company shall provide, free from preemptive rights, out of its authorized but
unissued shares or shares held in treasury, sufficient shares of Common Stock
to provide for the conversion of the Notes from time to time as such Notes are
presented for conversion.

                 Before taking any action which would cause an adjustment
reducing the Conversion Price below the then par value, if any, of the shares
of Common Stock issuable upon conversion of the Notes, the Parent Company will
take all corporate action which may, in the opinion of its counsel, be
necessary in order that the Parent Company may validly and legally issue shares
of such Common Stock at such adjusted Conversion Price.

                 The Parent Company covenants that all shares of Common Stock
which may be issued upon conversion of Notes will upon issue be fully paid and
non-assessable by the Parent Company and free from all taxes (to the extent
provided in Section 4.07), liens and charges with respect to the issue thereof.





<PAGE>   38
                                       34

                 The Parent Company covenants that if any shares provided of
Common Stock to be provided for the purpose of conversion of Notes hereunder
require registration with or approval of any governmental authority under any
federal or state law before such shares may be validly issued upon conversion,
the Parent Company will in good faith and as expeditiously as possible endeavor
to secure such registration or approval, as the case may be.

                 The Parent Company further covenants that if at any time the
Common Stock shall be listed on the Nasdaq National Market or any other
national securities exchange or automated quotation system the Parent Company
will, if permitted by the rules of such exchange or automated quotation system,
list and keep listed, so long as the Common Stock shall be so listed on such
exchange or automated quotation system, all Common Stock issuable upon
conversion of the Notes.

                 SECTION 4.09  Responsibility of Trustee.    The Trustee and
any other conversion agent shall not at any time be under any duty or
responsibility to any Holder of Notes to determine the Conversion Price or
whether any facts exist which may require any adjustment of the Conversion
Price, or with respect to the nature or extent or calculation of any such
adjustment when made, or with respect to the method employed, or herein or in
any supplemental indenture provided to be employed, in making the same.  The
Trustee and any other conversion agent shall not be accountable with respect to
the validity or value (or the kind or amount) of any shares of Common Stock of
the Parent Company, or of any securities or property, which may at any time be
issued or delivered upon the conversion of any Note; and the Trustee and any
other conversion agent make no representations with respect thereto.  Neither
the Trustee nor any conversion agent shall be responsible for any failure of
the Issuer or the Parent Company to issue, transfer or deliver any shares of
Common Stock of the Parent Company or stock certificates or other securities or
property or cash upon the surrender of any Note for the purpose of conversion
or to comply with any of the duties, responsibilities or covenants of the
Issuer or the Parent Company contained in this Article.  Without limiting the
generality of the foregoing, neither the Trustee nor any conversion agent shall
be under any responsibility to determine the correctness of any provisions
contained in any supplemental indenture entered into pursuant to Section 4.06
relating either to the kind or amount of shares of stock or securities or
property (including cash) receivable by Noteholders upon the conversion of
their Notes after any event referred to in such Section 4.06 or to any
adjustment to be made with respect thereto, but, subject to the provisions of
Section 6.01 of the Subordinated Indenture, may accept as conclusive evidence
of the correctness  of any such provisions, and shall be protected in relying
upon, the Officers' Certificate (which the Issuer and the Parent Company shall
be obligated to file with the Trustee prior to the execution of any such
supplemental indenture) with respect thereto.

                 SECTION 4.10  Notice to Holders Prior to Certain Actions.  In
the event:

                 (a)      the Parent Company shall declare a dividend (or any
         other distribution) on its Common Stock that would require an
         adjustment in the Conversion Price pursuant to Section 4.05; or





<PAGE>   39
                                       35

                 (b)      the Parent Company shall authorize the granting to
         the holders of its Common Stock of rights or warrants to subscribe for
         or purchase any share of any class or any other rights or warrants; or

                 (c)      of any reclassification or reorganization of the
         Common Stock of the Parent Company (other than a subdivision or
         combination of its outstanding common Stock, or a change in par value,
         or from par value to no par value, or from no par value to par value),
         or of any consolidation or merger to which the Parent Company is a
         party and for which approval of any stockholders of the Parent Company
         required, or of the sale or transfer of all or substantially all of
         the assets of the Parent Company; or

                 (d)      of the voluntary or involuntary dissolution,
liquidation or winding-up of the Parent Company;

the Parent Company shall cause to be filed with the Trustee and to be mailed to
each Holder of Notes at such Holder's address appearing on the note register
provided for in Section 2.08 of the Subordinated Indenture, as promptly as
possible but in any event at least fifteen (15) days prior to the applicable
date hereinafter specified, a notice stating (x) the date on which a record is
to be taken for the purpose of such dividend, distribution or rights or
warrants, or, if a record is not to be taken, the date as of which the holders
of Common Stock of the Parent Company of record to be entitled to such
dividend, distribution or rights are to be determined, or (y) the date on which
such reclassification, consolidation, merger, sale, transfer, dissolution,
liquidation or winding-up is expected to become effective or occur, and the
date as of which it is expected that holders of Common Stock of the Parent
Company of record shall be entitled to exchange their Common Stock for
securities or other property deliverable upon such reclassification,
consolidation, merger, sale, transfer, dissolution, liquidation or winding-up.
Failure to give such notice, or any defect therein, shall not affect the
legality or validity of such dividend, distribution, reclassification,
consolidation, merger, sale, transfer, dissolution, liquidation or winding-up.

                 SECTION 4.11  Conversion Agent.  The Trustee shall initially
serve as conversion agent for the Notes.


                                  ARTICLE FIVE

                               Certain Covenants

                 SECTION 5.01  Office of the Parent Company.  So long as any
Notes are convertible into Common Stock of the Parent Company in accordance
with the terms of this Supplemental Indenture, the Parent Company shall
maintain in the Borough of Manhattan, The City of New York, an office or agency
where the Notes may be surrendered for conversion into Common Stock of the
Parent Company (the "Parent Company Office").  The Parent Company and the
Issuer covenant and agree for the benefit of the Holders that the office or
agency of the Issuer maintained in the Borough of Manhattan, The City of New
York pursuant to Section 3.02 of the Subordinated Indenture shall serve as the
Parent Company Office.

                 SECTION 5.02  Limitation on Senior Subordinated Indebtedness.
The Parent Company will not, and will not permit any Subsidiary Guarantor to,
Incur any Indebtedness that is expressly made subordinate in right of payment
to any Senior Indebtedness or Guarantor Senior Indebtedness, as the case may
be, unless such Indebtedness, by its terms or by the terms of any agreement or
instrument pursuant to which such Indebtedness is outstanding, is expressly
made pari passu with, or subordinate in right of payment to, the Securities or
the Note Guarantee of such Guarantor, as the case may be, pursuant to
provisions substantially similar to those contained in this Indenture.

                 SECTION 5.03  Limitation on Senior Indebtedness.  The Parent
Company will not, and will not permit the Issuer or any Subsidiary Guarantor
to, Incur any Indebtedness unless (i) in the case of such Indebtedness that is
secured, there is no outstanding unsecured Senior Indebtedness or Guarantor
Senior Indebtedness of the Issuer or any Guarantor, and (ii) in the case of
such Indebtedness that is unsecured Senior Indebtedness or unsecured Guarantor
Senior Indebtedness, there is no outstanding secured Indebtedness of the Issuer
or any Guarantor, other than Capital Lease Obligations outstanding at any time
in an aggregate amount not to exceed $2.0 million.

                 The foregoing provision will be of no further force and effect
if (a) a supplemental indenture which eliminates the subordination provisions
set forth in Articles Six and Seven of this Supplemental Indenture and Articles
Twelve and Fourteen of the Subordinated Indenture, in form and substance
satisfactory to the Trustee, shall have been executed and delivered to the
Trustee, (b) the Trustee shall have received necessary consents with respect to
all outstanding Senior Indebtedness and Guarantor Senior Indebtedness from the
holders thereof approving such supplemental indenture, (c) the Trustee shall
have received such Opinions of Counsel as the Trustee may reasonably request,
and (d) immediately before and immediately after giving effect to such
supplemental indenture, no Default or Event of Default shall have occurred and
be continuing.

                 SECTION 5.04  Issuance of Certain Subsidiary Guarantees.  If
and to the extent the same has not occurred as of the date of this Supplemental
Indenture, the Issuer and the Parent Company shall, within 30 days of the date
of final prospectus relating to the public offering of the Notes, cause each of
Metrol Security Services, Inc., a Delaware corporation ("Metrol"), and Sonitrol
of Arizona, Inc.  ("Sonitrol"), an Arizona corporation, each of which is a
Subsidiary of the Parent Company, to be merged with and into the Issuer, and if
either Metrol or Sonitrol is not so merged within such 30-day period, cause
Metrol or Sonitrol, as the case may be, to execute and deliver an indenture
supplemental to the Subordinated Indenture providing for a Note Guarantee of
payment of the Notes by Metrol or Sonitrol, as the case may be, pursuant to
Article Thirteen of the Subordinated Indenture.


                                  ARTICLE SIX

                 SECTION 6.01  Notes Subordinated to Senior Indebtedness.
Notwithstanding any other provision of this Indenture, the Issuer and the
Trustee each covenants and agrees, and each Holder, by its acceptance of a
Note, likewise covenants and agrees, that all Notes shall be issued subject to
the provisions of this Article Six; and each Person holding any Note, whether
upon original issue or upon transfer, assignment or exchange thereof, accepts
and agrees that Senior Subordinated Obligations shall, to the extent set forth
in this Article Six, be subordinated in right of payment to the prior payment
in full, in cash or cash equivalents, of all amounts that constitute Senior
Indebtedness of the Issuer, including, without limitation, the Issuer's
obligations under the Credit Agreement.

                 SECTION 6.02  No Payment on Securities or Coupons in Certain
Circumstances.

                 (a)      No direct or indirect payment by or on behalf of the
Issuer of Senior Subordinated Obligations, whether pursuant to the terms of the
Securities or of any Coupons or upon acceleration or otherwise, shall be made
if, at the time of such payment, there exists a default in the payment of all
or any portion of the obligations of any Senior Indebtedness, and such default
shall not have been cured or waived or the benefits of this provision waived by
or on behalf of the holders of such Senior Indebtedness.

                 (b)      During the continuance of any other event of default
with respect to (i) the Credit Agreement pursuant to which the maturity thereof
may be accelerated and (A) upon receipt by the Trustee of written notice from
the Credit Agreement Agent or (B) if such event of default under the Credit
Agreement results from the acceleration of the Securities, from and after the
date of such acceleration, no payment of Senior Subordinated Obligations may be
made by or on behalf of the Issuer upon or in respect of the Securities for a
period (a "Payment Blockage Period") commencing on the earlier of the date of
receipt of such notice or the date of such acceleration and ending 179 days
thereafter (unless such Payment Blockage Period shall be terminated by written
notice to the Trustee from the Credit Agreement Agent or by repayment in full
in cash or cash equivalents of such Senior Indebtedness or such event of
default has been cured or waived) or (ii) any other Designated Senior
Indebtedness pursuant to which the maturity thereof may be accelerated, upon
receipt by the Trustee of written notice from the trustee or other
representative for the holders of such other Designated Senior Indebtedness (or
the holders of at least a majority in principal amount of such other Designated
Senior Indebtedness then outstanding), no payment of Senior Subordinated
Obligations may be made by or on behalf of the Issuer upon or in respect of the
Notes for a Payment Blockage Period commencing on the date of receipt of such
notice and ending 119 days thereafter (unless, in each case, such Payment
Blockage Period shall be terminated by written notice to the Trustee from such
trustee of, or other representative for, such holders or by repayment in full
in cash or cash equivalents of such Designated Senior Indebtedness or such
event of default has been cured or waived).  Not more than one Payment Blockage
Period pursuant to this Section 6.02(b) may be commenced with respect to the
Notes during any period of 360 consecutive days; provided that, subject to the
limitations set forth in the next sentence, the commencement of a Payment
Blockage Period by the representatives for, or the holders of, Designated
Senior Indebtedness, other than under the Credit Agreement or under clause
(i)(B) of this paragraph, shall not bar the commencement of another Payment
Blockage Period by the Credit Agreement Agent within such period of 360
consecutive days.  Notwithstanding anything in this Indenture to the contrary,
there must be 180





<PAGE>   42
                                       38

consecutive days in any 360-day period in which no Payment Blockage Period is
in effect.  For all purposes of this Section 6.02(b), no event of default that
existed or was continuing (it being acknowledged that any subsequent action
that would give rise to an event of default pursuant to any provision under
which an event of default previously existed or was continuing shall constitute
a new event of default for this purpose) on the date of the commencement of any
Payment Blockage Period with respect to the Designated Senior Indebtedness
initiating such Payment Blockage Period shall be, or shall be made, the basis
for the commencement of a second Payment Blockage Period by the representative
for, or the holders of, such Designated Senior Indebtedness, whether or not
within a period of 360 consecutive days, unless such event of default shall
have been cured or waived for a period of not less than 90 consecutive days.

                 (c)      In the event that, notwithstanding the foregoing, any
payment shall be received by the Trustee or any Holder when such payment is
prohibited by Section 6.02(a) or 6.02(b), the Trustee shall promptly notify the
holders of Senior Indebtedness of such prohibited payment and such payment
shall be held in trust for the benefit of, and shall be paid over or delivered
to, the holders of Senior Indebtedness or their respective representatives, or
to the trustee or trustees under any indenture pursuant to which any of such
Senior Indebtedness may have been issued, as their respective interests may
appear, but only to the extent that, upon notice from the Trustee to the
holders of Senior Indebtedness that such prohibited payment has been made, the
holders of the Senior Indebtedness (or their representative or representatives
of a trustee) within 30 days of receipt of such notice from the Trustee notify
the Trustee of the amounts then due and owing on the Senior Indebtedness, if
any, and only the amounts specified in such notice to the Trustee shall be paid
to the holders of Senior Indebtedness and any excess above such amounts due and
owing on Senior Indebtedness shall be paid to the Issuer.

                 SECTION 6.03  Payment over of Proceeds upon Dissolution, Etc.

                 (a)      Upon any payment or distribution of assets or
securities of the Issuer of any kind or character, whether in cash, property or
securities, in connection with any dissolution or winding up or total or
partial liquidation or reorganization of the Issuer, whether voluntary or
involuntary, or in a bankruptcy, insolvency, receivership or other proceedings,
all amounts due or to become due upon all Senior Indebtedness shall first be
paid in full, in cash or cash equivalents, before the Holders or the Trustee on
their behalf shall be entitled to receive any payment by the Issuer on account
of Senior Subordinated Obligations, or any payment to acquire any of the Notes
for cash, property or securities, or any distribution with respect to the Notes
of any cash, property or securities.  Before any payment may be made by, or on
behalf of, the Issuer on any Senior Subordinated Obligations in connection with
any such dissolution, winding up, liquidation or reorganization, any payment or
distribution of assets or securities of the Issuer of any kind or character,
whether in cash, property or securities, to which the Holders or the Trustee on
their behalf would be entitled, except for the provisions of this Article Six,
shall be made by the Issuer or by any receiver, trustee in bankruptcy,
liquidating trustee, agent or other similar Person making such payment or
distribution or by the Holders or the Trustee if received by them or it,
directly to the holders of the Senior Indebtedness (pro rata to such holders on
the basis of the respective amounts of Senior Indebtedness held by such
holders) or their representatives or to any trustee or trustees under any
indenture pursuant to which any such Senior Indebtedness may have been issued,
as their respective interests appear, to the extent





<PAGE>   43
                                       39

necessary to pay all such Senior Indebtedness in full, in cash or cash
equivalents, after giving effect to any concurrent payment, distribution or
provision therefor to or for the holders of such Senior Indebtedness.

                 (b)      To the extent any payment of Senior Indebtedness
(whether by or on behalf of the Issuer, as proceeds of security or enforcement
of any right of setoff or otherwise) is declared to be fraudulent or
preferential, set aside or required to be paid to any receiver, trustee in
bankruptcy, liquidating trustee, agent or other similar Person under any
bankruptcy, insolvency, receivership, fraudulent conveyance or similar law,
then if such payment is recovered by, or paid over to, such receiver, trustee
in bankruptcy, liquidating trustee, agent or other similar Person, the Senior
Indebtedness or part thereof originally intended to be satisfied shall be
deemed to be reinstated and outstanding as if such payment had not occurred.
To the extent the obligation to repay any Senior Indebtedness is declared to be
fraudulent, invalid or otherwise set aside under any bankruptcy, insolvency,
receivership, fraudulent conveyance or similar law, then the obligations so
declared fraudulent, invalid or otherwise set aside (and all other amounts that
would come due with respect thereto had such obligation not been so affected)
shall be deemed to be reinstated and outstanding as Senior Indebtedness for all
purposes of this Indenture as if such declaration, invalidity or setting aside
had not occurred.

                 (c)      In the event that, notwithstanding the foregoing
provision prohibiting such payment or distribution, any payment or distribution
of assets or securities of the Issuer of any kind or character, whether in
cash, property or securities, shall be received by the Trustee or any Holder at
a time when such payment or distribution is prohibited by Section 6.03(a) and
before all obligations in respect of Senior Indebtedness are paid in full, in
cash or cash equivalents, such payment or distribution shall be received and
held in trust for the benefit of, and shall be paid over or delivered to, the
holders of Senior Indebtedness (pro rata to such holders on the basis of the
respective amounts of Senior Indebtedness held by such holders) or their
representatives or to the trustee or trustees under any indenture pursuant to
which any such Senior Indebtedness may have been issued, as their respective
interests appear, for application to the payment of Senior Indebtedness
remaining unpaid until all such Senior Indebtedness has been paid in full, in
cash or cash equivalents, after giving effect to any concurrent payment,
distribution or provision therefor to or for the holders of such Senior
Indebtedness.

                 (d)      The consolidation of the Issuer with, or the merger
of the Issuer with or into, another Person or the liquidation or dissolution of
the Issuer following the sale, conveyance, transfer, lease or other disposition
of all or substantially all of its property and assets to another Person upon
the terms and conditions provided in Article Nine of the Subordinated Indenture
shall not be deemed a dissolution, winding up, liquidation or reorganization
for the purposes of this Section 6.03 if such other Person shall, as a part of
such consolidation, merger, sale, conveyance, transfer, lease or other
disposition, comply (to the extent required) with the conditions stated in
Article Nine of the Subordinated Indenture.

                 SECTION 6.04  Subrogation.

                 (a)      Upon the payment in full of all Senior Indebtedness
in cash or cash equivalents, the Holders shall be subrogated to the rights of
the holders of Senior Indebtedness to





<PAGE>   44
                                       40

receive payments or distributions of cash, property or securities of the Issuer
made on such Senior Indebtedness until the principal of and interest on the
Notes shall be paid in full; and, for the purposes of such subrogation, no
payments or distributions to the holders of such Senior Indebtedness of any
cash, property or securities to which the Holders or the Trustee on their
behalf would be entitled except for the provisions of this Article Six, and no
payment pursuant to the provisions of this Article Six to the holders of Senior
Indebtedness by Holders or the Trustee on their behalf shall, as between the
Issuer, its creditors other than holders of Senior Indebtedness, and the
Holders, be deemed to be a payment by the Issuer to or on account of the Senior
Indebtedness.  It is understood that the provisions of this Article Six are
intended solely for the purpose of defining the relative rights of the Holders,
on the one hand, and the holders of the Senior Indebtedness, on the other hand.

                 (b)      If any payment or distribution to which the Holders
would otherwise have been entitled but for the provisions of this Article Six
shall have been applied, pursuant to the provisions of this Article Six, to the
payment of all amounts payable under Senior Indebtedness, then, and in such
case, the Holders shall be entitled to receive from the holders of such Senior
Indebtedness any payments or distributions received by such holders of such
Senior Indebtedness in excess of the amount required to make payment in full,
in cash or cash equivalents, of such Senior Indebtedness of such holders.

                 SECTION 6.05  Obligations of the Issuer Unconditional.

                 (a)      Nothing contained in this Article Six or elsewhere in
this Indenture or in the Notes is intended to or shall impair, as among the
Issuer and the Holders, the obligation of the Issuer, which is absolute and
unconditional, to pay to the Holders the principal of and interest on the Notes
as and when the same shall become due and payable in accordance with their
terms, or is intended to or shall affect the relative rights of the Holders and
creditors of the Issuer other than the holders of the Senior Indebtedness, nor
shall anything herein or therein prevent the Holders or the Trustee on their
behalf from exercising all remedies otherwise permitted by applicable law upon
default under this Indenture, subject to the rights, if any, under this Article
Six of the holders of the Senior Indebtedness.

                 (b)      Without limiting the generality of the foregoing,
nothing contained in this Article Six will restrict the right of the Trustee or
the Holders to take any action to declare the Notes to be due and payable prior
to their maturity pursuant to Section 5.01 of the Subordinated Indenture or to
pursue any rights or remedies hereunder; provided, however, that all Senior
Indebtedness then due and payable or thereafter declared to be due and payable
shall first be paid in full, in cash or cash equivalents, before the Holders or
the Trustee are entitled to receive any direct or indirect payment from the
Issuer of Senior Subordinated Obligations.

                 SECTION 6.06  Notice to Trustee.

                 (a)      The Issuer shall give prompt written notice to the
Trustee of any fact known to the Issuer that would prohibit the making of any
payment to or by the Trustee in respect of the Notes pursuant to the provisions
of this Article Six.  The Trustee shall not be charged with knowledge of the
existence of any default or event of default with respect to any





<PAGE>   45
                                       41

Senior Indebtedness or of any other facts that would prohibit the making of any
payment to or by the Trustee unless and until the Trustee shall have received
notice in writing at its Corporate Trust Office to that effect signed by an
Officer of the Issuer, or by a holder of Senior Indebtedness or trustee or
agent thereof; and prior to the receipt of any such written notice, the Trustee
shall, subject to Article Six of the Subordinated Indenture, be entitled to
assume that no such facts exist; provided that, if the Trustee shall not have
received the notice provided for in this Section 6.06 at least two Business
Days prior to the date upon which, by the terms of this Indenture, any monies
shall become payable for any purpose (including, without limitation, the
payment of the principal of or interest on any Note), then, notwithstanding
anything herein to the contrary, the Trustee shall have full power and
authority to receive any monies from the Issuer and to apply the same to the
purpose for which they were received, and shall not be affected by any notice
to the contrary that may be received by it on or after such prior date except
for an acceleration of the Notes prior to such application.  Nothing contained
in this Section 6.06 shall limit the right of the holders of Senior
Indebtedness to recover payments as contemplated by this Article Six.  The
foregoing shall not apply if the paying agent is the Issuer.  The Trustee shall
be entitled to rely on the delivery to it of a written notice by a Person
representing himself or itself to be a holder of any Senior Indebtedness (or a
trustee on behalf of, or other representative of, such holder) to establish
that such notice has been given by a holder of such Senior Indebtedness or a
trustee or representative on behalf of any such holder.

                 (b)      In the event that the Trustee determines in good
faith that any evidence is required with respect to the right of any Person as
a holder of Senior Indebtedness to participate in any payment or distribution
pursuant to this Article Six, the Trustee may request such Person to furnish
evidence to the reasonable satisfaction of the Trustee as to the amount of
Senior Indebtedness held by such Person, the extent to which such Person is
entitled to participate in such payment or distribution and any other facts
pertinent to the rights of such Person under this Article Six and, if such
evidence is not furnished to the Trustee, the Trustee may defer any payment to
such Person pending judicial determination as to the right of such Person to
receive such payment.

                 SECTION 6.07  Reliance on Judicial Order or Certificate of
Liquidating Agent.  Upon any payment or distribution of assets or securities
referred to in this Article Six, the Trustee and the Holders shall be entitled
to rely upon any order or decree made by any court of competent jurisdiction in
which bankruptcy, dissolution, winding up, liquidation or reorganization
proceedings are pending, or upon a certificate of the receiver, trustee in
bankruptcy, liquidating trustee, agent or other similar Person making such
payment or distribution, delivered to the Trustee or to the Holders for the
purpose of ascertaining the persons entitled to participate in such
distribution, the holders of the Senior Indebtedness and other Indebtedness of
the Issuer, the amount thereof or payable thereon, the amount or amounts paid
or distributed thereon and all other facts pertinent thereto or to this Article
Six.

                 SECTION 6.08  Trustee's Relation to Senior Indebtedness.

                 (a)      The Trustee and any paying agent shall be entitled to
all the rights set forth in this Article Six with respect to any Senior
Indebtedness that may at any time be held by it in its individual or any other
capacity to the same extent as any other holder of Senior Indebtedness





<PAGE>   46
                                       42

and nothing in this Indenture shall deprive the Trustee or any paying agent of
any of its rights as such holder.

                 (b)      With respect to the holders of Senior Indebtedness,
the Trustee undertakes to perform or to observe only such of its covenants and
obligations as are specifically set forth in this Article Six, and no implied
covenants or obligations with respect to the holders of Senior Indebtedness
shall be read into this Indenture against the Trustee.  The Trustee shall not
be deemed to owe any fiduciary duty to the holders of Senior Indebtedness
(except as provided in Section 6.02(c) and Section 6.03(c)).

                 SECTION 6.09  Subordination Rights Not Impaired by Acts or
Omissions of the Issuer or Holders of Senior Indebtedness.  No right of any
present or future holders of any Senior Indebtedness to enforce subordination
as provided in this Article Six will at any time in any way be prejudiced or
impaired by any act or failure to act on the part of the Issuer or by any act
or failure to act, in good faith, by any such holder, or by any noncompliance
by the Issuer with the terms of this Indenture, regardless of any knowledge
thereof that any such holder may have or otherwise be charged with.  The
provisions of this Article Six are intended to be for the benefit of, and shall
be enforceable directly by, the holders of Senior Indebtedness.

                 SECTION 6.10  Holders Authorize Trustee to Effectuate
Subordination of the Notes.  Each Holder, by such Holder's acceptance of any
Notes, authorizes and expressly directs the Trustee on such Holder's behalf to
take such action as may be necessary or appropriate to effectuate the
subordination provided in this Article Six, and appoints the Trustee such
Holder's attorney-in-fact for such purposes, including, in the event of any
dissolution, winding up, liquidation or reorganization of the Issuer (whether
in bankruptcy, insolvency, receivership, reorganization or similar proceedings
or upon an assignment for the benefit of creditors or otherwise) tending
towards liquidation of the property and assets of the Issuer, the filing of a
claim for the unpaid balance of its Notes, if any, in the form required in
those proceedings.  If the Trustee does not file a proper claim or proof of
indebtedness in the form required in such proceeding at least 30 days before
the expiration of the time to file such claim or claims, each holder of Senior
Indebtedness is hereby authorized to file an appropriate claim for and on
behalf of the Holders.

                 SECTION 6.11  Not to Prevent Events of Default.  The failure
to make a payment on account of principal of or interest on the Notes by reason
of any provision of this Article Six will not be construed as preventing the
occurrence of an Event of Default.

                 SECTION 6.12  Trustee's Compensation Not Prejudiced.  Nothing
in this Article Six will apply to amounts due to the Trustee pursuant to other
sections of this Indenture.

                 SECTION 6.13  No Waiver of Subordination Provisions.  Without
in any way limiting the generality of Section 6.09, the holders of Senior
Indebtedness may, at any time and from time to time, without the consent of or
notice to the Trustee or the Holders, without incurring responsibility to the
Holders and without impairing or releasing the subordination provided in this
Article Six or the obligations hereunder of the Holders to the holders of
Senior Indebtedness, do any one or more of the following:  (a) change the
manner, place or terms of





<PAGE>   47
                                       43

payment or extend the time of payment of, or renew or alter, Senior
Indebtedness or any instrument evidencing the same or any agreement under which
Senior Indebtedness is outstanding or secured; (b) sell, exchange, release or
otherwise deal with any property pledged, mortgaged or otherwise securing
Senior Indebtedness; (c) release any Person liable in any manner for the
collection of Senior Indebtedness; and (d) exercise or refrain from exercising
any rights against the Issuer and any other Person.

                 SECTION 6.14  Payments May Be Paid Prior to Dissolution.
Nothing contained in this Article Six or elsewhere in this Indenture shall
prevent (i) the Issuer, except under the conditions described in Section 6.02
or Section 6.03, from making payments of principal of and interest on the
Notes, or from depositing with the Trustee any money for such payments, or (ii)
the application by the Trustee of any money deposited with it for the purpose
of making such payments of principal of and interest on the Notes to the
Holders entitled thereto unless, at least two Business Days prior to the date
upon which such payment becomes due and payable, the Trustee shall have
received the written notice provided for in Section 6.02(b) (or there shall
have been an acceleration of the Notes prior to such application) or in Section
6.06.  The Issuer shall give prompt written notice to the Trustee of any
dissolution, winding up, liquidation or reorganization of the Issuer.


                                 ARTICLE SEVEN

                        Subordination of Note Guarantees

                 SECTION 7.01  Note Guarantees Subordinated to Guarantor Senior
Indebtedness.  Notwithstanding any other provision of this Indenture, each
Guarantor and the Trustee each covenants and agrees, and each Holder, by its
acceptance of a Note, likewise covenants and agrees, that the Note Guarantee of
each Guarantor shall be subject to the provisions of this Article Seven; and
each Person holding any Note, whether upon original issue or upon transfer,
assignment or exchange thereof, accepts and agrees that all payments pursuant
to any Note Guarantee shall, to the extent set forth in this Article Seven, be
subordinated in right of payment to the prior payment in full, in cash or cash
equivalents, of all amounts payable under the Guarantor Senior Indebtedness of
the issuer of such Note Guarantee, including, without limitation, such
Guarantor's obligations, if any, under the Credit Agreement.

                 SECTION 7.02  No Payment on Note Guarantees in Certain
Circumstances.

                 (a)      No direct or indirect payment by or on behalf of any
Guarantor pursuant to the Note Guarantee of such Guarantor shall be made if, at
the time of such payment, there exists a default in the payment of all or any
portion of the obligations of any Guarantor Senior Indebtedness, and such
default shall not have been cured or waived or the benefits of this provision
waived by or on behalf of the holders of such Guarantor Senior Indebtedness.

                 (b)      During the continuance of any other event of default
with respect to (i) the Credit Agreement pursuant to which the maturity thereof
may be accelerated and (A) upon receipt by the Trustee of written notice from
the Credit Agreement Agent or (B) if such event of





<PAGE>   48
                                       44

default under the Credit Agreement results from the acceleration of the Notes,
from and after the date of such acceleration, no payment may be made by or on
behalf of any Guarantor pursuant to a Note Guarantee for a period (a "Guarantor
Payment Blockage Period") commencing on the earlier of the date of receipt of
such notice or the date of such acceleration and ending 179 days thereafter
(unless such Guarantor Payment Blockage Period shall be terminated by written
notice to the Trustee from the Credit Agreement Agent or by repayment in full
in cash or cash equivalents of such Senior Indebtedness of the Issuer or such
event of default has been cured or waived) or (ii) any other Designated Senior
Indebtedness (payment of which has been guaranteed by such Guarantor) pursuant
to which the maturity thereof may be accelerated, upon receipt by the Trustee
of written notice from the trustee or other representative for the holders of
such other Designated Senior Indebtedness (or the holders of at least a
majority in principal amount of such other Designated Senior Indebtedness then
outstanding), no payment pursuant to the Note Guarantee of such Guarantor may
be made by or on behalf of such Guarantor for a Guarantor Payment Blockage
Period commencing on the date of receipt of such notice and ending 119 days
thereafter (unless, in each case, such Guarantor Payment Blockage Period shall
be terminated by written notice to the Trustee from such trustee of, or other
representative for, such holders or by repayment in full in cash or cash
equivalents of such Designated Senior Indebtedness or such event of default has
been cured or waived).  Not more than one Guarantor Payment Blockage Period
pursuant to this Section 7.02(b) may be commenced with respect to any Note
Guarantee during any period of 360 consecutive days; provided that, subject to
the limitations set forth in the next sentence, the commencement of a Guarantor
Payment Blockage Period by the representatives for, or the holders of,
Designated Senior Indebtedness, other than under the Credit Agreement or under
clause (i)(B) of this paragraph, shall not bar the commencement of another
Guarantor Payment Blockage Period by the Credit Agreement Agent within such
period of 360 consecutive days.  Notwithstanding anything in this Indenture to
the contrary, with respect to such Note Guarantee, there must be 180
consecutive days in any 360-day period in which, with respect to such Note
Guarantee, no Guarantor Payment Blockage Period is in effect.  For all purposes
of this Section 7.02(b), no event of default that existed or was continuing (it
being acknowledged that any subsequent action that would give rise to an event
of default pursuant to any provision under which an event of default previously
existed or was continuing shall constitute a new event of default for this
purpose) on the date of the commencement of any Guarantor Payment Blockage
Period with respect to the Designated Senior Indebtedness initiating such
Guarantor Payment Blockage Period shall be, or shall be made, the basis for the
commencement of a second Guarantor Payment Blockage Period by the
representative for, or the holders of, such Designated Senior Indebtedness,
whether or not within a period of 360 consecutive days, unless such event of
default shall have been cured or waived for a period of not less than 90
consecutive days.

                 SECTION 7.03  Payment over of Proceeds upon Dissolution, Etc.

                 (a)      Upon any payment or distribution of assets or
securities of any Guarantor of any kind or character, whether in cash, property
or securities, in connection with any dissolution or winding up or total or
partial liquidation or reorganization of such Guarantor, whether voluntary or
involuntary, or in a bankruptcy, insolvency, receivership or other proceedings,
all amounts due or to become due upon all Guarantor Senior Indebtedness of such
Guarantor shall first be paid in full, in cash or cash equivalents, before the
Holders or the Trustee





<PAGE>   49
                                       45

on their behalf shall be entitled to receive any payment by such Guarantor on
account of its Note Guarantee, or any payment by such Guarantor to acquire any
of the Notes for cash, property or securities, or any distribution with respect
to the Notes of any cash, property or securities.  Before any payment may be
made by, or on behalf of, any Guarantor pursuant to such Guarantor's Note
Guarantee in connection with any such dissolution, winding up, liquidation or
reorganization, any payment or distribution of assets or securities of such
Guarantor of any kind or character, whether in cash, property or securities, to
which the Holders or the Trustee on their behalf would be entitled, except for
the provisions of this Article Seven, shall be made by such Guarantor or by any
receiver, trustee in bankruptcy, liquidating trustee, agent or other similar
Person making such payment or distribution or by the Holders or the Trustee if
received by them or it, directly to the holders of the Guarantor Senior
Indebtedness of such Guarantor (pro rata to such holders on the basis of the
respective amounts of Guarantor Senior Indebtedness held by such holders) or
their representatives or to any trustee or trustees under any indenture
pursuant to which any such Guarantor Senior Indebtedness may have been issued,
as their respective interests appear, to the extent necessary to pay all such
Guarantor Senior Indebtedness in full, in cash or cash equivalents, after
giving effect to any concurrent payment, distribution or provision therefor to
or for the holders of such Guarantor Senior Indebtedness.

                 (b)      To the extent any payment of Guarantor Senior
Indebtedness of any Guarantor (whether by or on behalf of such Guarantor, as
proceeds of security or enforcement of any right of setoff or otherwise) is
declared to be fraudulent or preferential, set aside or required to be paid to
any receiver, trustee in bankruptcy, liquidating trustee, agent or other
similar Person under any bankruptcy, insolvency, receivership, fraudulent
conveyance or similar law, then if such payment is recovered by, or paid over
to, such receiver, trustee in bankruptcy, liquidating trustee, agent or other
similar Person, the Guarantor Senior Indebtedness of such Guarantor or part
thereof originally intended to be satisfied shall be deemed to be reinstated
and outstanding as if such payment had not occurred.  To the extent the
obligation to repay any Guarantor Senior Indebtedness of such Guarantor is
declared to be fraudulent, invalid or otherwise set aside under any bankruptcy,
insolvency, receivership, fraudulent conveyance or similar law, then the
obligations so declared fraudulent, invalid or otherwise set aside (and all
other amounts that would come due with respect thereto had such obligation not
been so affected) shall be deemed to be reinstated and outstanding as Guarantor
Senior Indebtedness of such Guarantor for all purposes of this Indenture as if
such declaration, invalidity or setting aside had not occurred.

                 (c)      In the event that, notwithstanding the foregoing
provision prohibiting such payment or distribution, any payment or distribution
of assets or securities of any Guarantor of any kind or character, whether in
cash, property or securities, shall be received by the Trustee or any Holder at
a time when such payment or distribution is prohibited by Section 7.03(a) and
before all obligations in respect of Guarantor Senior Indebtedness of such
Guarantor are paid in full, in cash or cash equivalents, such payment or
distribution shall be received and held in trust for the benefit of, and shall
be paid over or delivered to, the holders of Guarantor Senior Indebtedness of
such Guarantor (pro rata to such holders on the basis of the respective amounts
of Guarantor Senior Indebtedness held by such holders) or their representatives
or to the trustee or trustees under any indenture pursuant to which any such
Guarantor Senior Indebtedness may have been issued, as their respective
interests appear, for application to the payment of





<PAGE>   50
                                       46

Guarantor Senior Indebtedness remaining unpaid until all such Guarantor Senior
Indebtedness has been paid in full, in cash or cash equivalents, after giving
effect to any concurrent payment, distribution or provision therefor to or for
the holders of such Guarantor Senior Indebtedness.

                 (d)      The consolidation of any Guarantor with, or the
merger of any Guarantor with or into, another Person or the liquidation or
dissolution of any Guarantor following the sale, conveyance, transfer, lease or
other disposition of all or substantially all of its property and assets to
another Person upon the terms and conditions provided in Article Nine of the
Subordinated Indenture shall not be deemed a dissolution, winding up,
liquidation or reorganization for the purposes of this Section 7.03 if such
other Person shall, as a part of such consolidation, merger, sale, conveyance,
transfer, lease or other disposition, comply (to the extent required) with the
conditions stated in Article Nine of the Subordinated Indenture.

                 SECTION 7.04  Subrogation.

                 (a)      Upon the payment in full of all Guarantor Senior
Indebtedness of any Guarantor in cash or cash equivalents, the Holders shall be
subrogated to the rights of the holders of Guarantor Senior Indebtedness to
receive payments or distributions of cash, property or securities of such
Guarantor made on such Guarantor Senior Indebtedness until the principal of and
interest on the Securities and any Coupons appertaining thereto shall be paid
in full; and, for the purposes of such subrogation, no payments or
distributions to the holders of such Guarantor Senior Indebtedness of any cash,
property or securities to which the Holders or the Trustee on their behalf
would be entitled except for the provisions of this Article Seven, and no
payment pursuant to the provisions of this Article Seven to the holders of
Guarantor Senior Indebtedness by Holders or the Trustee on their behalf shall,
as between such Guarantor, its creditors other than holders of Guarantor Senior
Indebtedness, and the Holders, be deemed to be a payment by such Guarantor to
or on account of such Guarantor Senior Indebtedness.  It is understood that the
provisions of this Article Seven are intended solely for the purpose of
defining the relative rights of the Holders, on the one hand, and the holders
of such Guarantor Senior Indebtedness, on the other hand.

                 (b)      If any payment or distribution to which the Holders
would otherwise have been entitled but for the provisions of this Article Seven
shall have been applied, pursuant to the provisions of this Article Seven, to
the payment of all amounts payable under the Guarantor Senior Indebtedness of a
Guarantor, then, and in such case, the Holders shall be entitled to receive
from the holders of such Guarantor Senior Indebtedness any payments or
distributions received by such holders of such Guarantor Senior Indebtedness in
excess of the amount required to make payment in full, in cash or cash
equivalents, of such Guarantor Senior Indebtedness of such holders.

                 SECTION 7.05  Obligations of Guarantors Unconditional.

                 (a)      Nothing contained in this Article Seven or elsewhere
in this Indenture or in the Notes is intended to or shall impair, as among any
Guarantor and the Holders, the obligation of such Guarantor, which, pursuant to
the Note Guarantee of such Guarantor is absolute and unconditional, to pay to
the Holders the principal of and interest on the Notes as





<PAGE>   51
                                       47

and when the same shall become due and payable in accordance with their terms,
or is intended to or shall affect the relative rights of the Holders and
creditors of such Guarantor other than the holders of the Guarantor Senior
Indebtedness of such Guarantor, nor shall anything herein or therein prevent
the Holders or the Trustee on their behalf from exercising all remedies
otherwise permitted by applicable law upon default under this Indenture,
subject to the rights, if any, under this Article Seven of the holders of the
Guarantor Senior Indebtedness of such Guarantor.

                 (b)      Without limiting the generality of the foregoing,
nothing contained in this Article Seven will restrict the right of the Trustee
or the Holders to take any action to declare the Notes to be due and payable
prior to their maturity pursuant to Section 5.01 of the Subordinated Indenture
or to pursue any rights or remedies hereunder; provided, however, that all
Guarantor Senior Indebtedness of a Guarantor then due and payable or thereafter
declared to be due and payable shall first be paid in full, in cash or cash
equivalents, before the Holders or the Trustee are entitled to receive any
direct or indirect payment from such Guarantor on account of its Note
Guarantee.

                 SECTION 7.06  Notice to Trustee.

                 (a)      Each Guarantor shall give prompt written notice to
the Trustee of any fact known to such Guarantor that would prohibit the making
of any payment to or by the Trustee in respect of the Notes pursuant to the
provisions of its Note Guarantee, Article Six of this Supplemental Indenture
and this Article Seven.  The Trustee shall not be charged with knowledge of the
existence of any default or event of default with respect to any Guarantor
Senior Indebtedness or of any other facts that would prohibit the making of any
payment to or by the Trustee unless and until the Trustee shall have received
notice in writing at its Corporate Trust Office to that effect signed by an
Officer of a Guarantor, or by a holder of Guarantor Senior Indebtedness or
trustee or agent thereof; and prior to the receipt of any such written notice,
the Trustee shall, subject to Article Six of the Subordinated Indenture, be
entitled to assume that no such facts exist; provided that, if the Trustee
shall not have received the notice provided for in this Section 7.06 at least
two Business Days prior to the date upon which, by the terms of this Indenture,
any monies shall become payable for any purpose (including, without limitation,
the payment of the principal of or interest on any Note), then, notwithstanding
anything herein to the contrary, the Trustee shall have full power and
authority to receive any monies from such Guarantor and to apply the same to
the purpose for which they were received, and shall not be affected by any
notice to the contrary that may be received by it on or after such prior date
except for an acceleration of the Notes prior to such application.  Nothing
contained in this Section 7.06 shall limit the right of the holders of
Guarantor Senior Indebtedness to recover payments as contemplated by this
Article Seven.  The foregoing shall not apply if the paying agent is such
Guarantor.  The Trustee shall be entitled to rely on the delivery to it of a
written notice by a Person representing himself or itself to be a holder of any
Guarantor Senior Indebtedness (or a trustee on behalf of, or other
representative of, such holder) to establish that such notice has been given by
a holder of such Guarantor Senior Indebtedness or a trustee or representative
on behalf of any such holder.

                 (b)      In the event that the Trustee determines in good
faith that any evidence is required with respect to the right of any Person as
a holder of Guarantor Senior Indebtedness to





<PAGE>   52
                                       48

participate in any payment or distribution pursuant to this Article Seven, the
Trustee may request such Person to furnish evidence to the reasonable
satisfaction of the Trustee as to the amount of Guarantor Senior Indebtedness
held by such Person, the extent to which such Person is entitled to participate
in such payment or distribution and any other facts pertinent to the rights of
such Person under this Article Seven and, if such evidence is not furnished to
the Trustee, the Trustee may defer any payment to such Person pending judicial
determination as to the right of such Person to receive such payment.

                 SECTION 7.07  Reliance on Judicial Order or Certificate of
Liquidating Agent.  Upon any payment or distribution of assets or securities
referred to in this Article Seven, the Trustee and the Holders shall be
entitled to rely upon any order or decree made by any court of competent
jurisdiction in which bankruptcy, dissolution, winding up, liquidation or
reorganization proceedings are pending, or upon a certificate of the receiver,
trustee in bankruptcy, liquidating trustee, agent or other similar Person
making such payment or distribution, delivered to the Trustee or to the Holders
for the purpose of ascertaining the persons entitled to participate in such
distribution, the holders of the Guarantor Senior Indebtedness and other
Indebtedness of a Guarantor, the amount thereof or payable thereon, the amount
or amounts paid or distributed thereon and all other facts pertinent thereto or
to this Article Seven.

                 SECTION 7.08  Trustee's Relation to Guarantor Senior
Indebtedness.

                 (a)      The Trustee and any paying agent shall be entitled to
all the rights set forth in this Article Seven with respect to any Guarantor
Senior Indebtedness that may at any time be held by it in its individual or any
other capacity to the same extent as any other holder of Guarantor Senior
Indebtedness and nothing in this Indenture shall deprive the Trustee or any
paying agent of any of its rights as such holder.

                 (b)      With respect to the holders of Guarantor Senior
Indebtedness, the Trustee undertakes to perform or to observe only such of its
covenants and obligations as are specifically set forth in this Article Seven,
and no implied covenants or obligations with respect to the holders of
Guarantor Senior Indebtedness shall be read into this Indenture against the
Trustee.  The Trustee shall not be deemed to owe any fiduciary duty to the
holders of Guarantor Senior Indebtedness (except as provided in Section 7.02(c)
and Section 7.03(c)).

                 SECTION 7.09  Subordination Rights Not Impaired by Acts or
Omissions of Guarantors or Holders of Guarantor Senior Indebtedness.  No right
of any present or future holders of any Guarantor Senior Indebtedness of any
Guarantor to enforce subordination as provided in this Article Seven will at
any time in any way be prejudiced or impaired by any act or failure to act on
the part of such Guarantor or by any act or failure to act, in good faith, by
any such holder, or by any noncompliance by such Guarantor with the terms of
this Indenture, regardless of any knowledge thereof that any such holder may
have or otherwise be charged with.  The provisions of this Article Seven are
intended to be for the benefit of, and shall be enforceable directly by, the
holders of Guarantor Senior Indebtedness.





<PAGE>   53
                                       49

                 SECTION 7.10  Holders Authorize Trustee to Effectuate
Subordination of  Note Guarantees.  Each Holder, by such Holder's acceptance of
any Notes, authorizes and expressly directs the Trustee on such Holder's behalf
to take such action as may be necessary or appropriate to effectuate the
subordination provided in this Article Seven, and appoints the Trustee such
Holder's attorney-in-fact for such purposes, including, in the event of any
dissolution, winding up, liquidation or reorganization of any Guarantor
(whether in bankruptcy, insolvency, receivership, reorganization or similar
proceedings or upon an assignment for the benefit of creditors or otherwise)
tending towards liquidation of the property and assets of such Guarantor, the
filing of a claim for the unpaid balance of its Notes in the form required in
those proceedings.  If the Trustee does not file a proper claim or proof of
indebtedness in the form required in such proceeding at least 30 days before
the expiration of the time to file such claim or claims, each holder of
Guarantor Senior Indebtedness is hereby authorized to file an appropriate claim
for and on behalf of the Holders.

                 SECTION 7.11  Not to Prevent Events of Default.  The failure
to make a payment on account of principal of or interest on the Notes by reason
of any provision of this Article Seven will not be construed as preventing the
occurrence of an Event of Default.

                 SECTION 7.12  Trustee's Compensation Not Prejudiced.  Nothing
in this Article Seven will apply to amounts due to the Trustee pursuant to
other sections of the Indenture.

                 SECTION 7.13  No Waiver of Subordination Provisions.  Without
in any way limiting the generality of Section 7.09, the holders of Guarantor
Senior Indebtedness may, at any time and from time to time, without the consent
of or notice to the Trustee or the Holders, without incurring responsibility to
the Holders and without impairing or releasing the subordination provided in
this Article Seven or the obligations hereunder of the Holders to the holders
of such Guarantor Senior Indebtedness, do any one or more of the following:
(a) change the manner, place or terms of payment or extend the time of payment
of, or renew or alter, such Guarantor Senior Indebtedness or any instrument
evidencing the same or any agreement under which such Guarantor Senior
Indebtedness is outstanding or secured; (b) sell, exchange, release or
otherwise deal with any property pledged, mortgaged or otherwise securing such
Guarantor Senior Indebtedness; (c) release any Person liable in any manner for
the collection of such Guarantor Senior Indebtedness; and (d) exercise or
refrain from exercising any rights against a Guarantor with respect to such
Guarantor Senior Indebtedness and any other Person.

                 SECTION 7.14  Payments May Be Paid Prior to Dissolution.
Nothing contained in this Article Seven or elsewhere in this Indenture shall
prevent (i) a Guarantor, except under the conditions described in Section 7.02
or Section 7.03, from making payments under the Note Guarantee of such
Guarantor with respect to the principal of and interest on the Notes, or from
depositing with the Trustee any money for such payments, or (ii) the
application by the Trustee of any money deposited with it for the purpose of
making such payments of principal of and interest on the Notes to the Holders
entitled thereto unless, at least two Business Days prior to the date upon
which such payment becomes due and payable, the Trustee shall have received the
written notice provided for in Section 7.02(b) (or there shall have been an
acceleration of the Securities or any Coupons appertaining thereto prior to
such application) or in Section 7.06.





<PAGE>   54
                                       50

Each Guarantor shall give prompt written notice to the Trustee of any
dissolution, winding up, liquidation or reorganization of such Guarantor.

respects confirmed and preserved.

                 Notwithstanding any provision to the contrary in Section 8.02
of the Subordinated Indenture, no supplemental indenture entered into by the
Issuer and the Trustee in accordance with Article Eight of the Subordinated
Indenture shall, without the consent of the Holder of each Outstanding Note
affected thereby, change or eliminate any of such Holder's rights under
Articles Three and Four hereof, or modify Articles Six or Seven hereof in a
manner adverse to such Holder.

                 It shall not be necessary for the consent of the Holders under
this Section 8.02 to approve the particular form of any proposed supplemental
indenture, but it shall be sufficient if such consent shall approve the
substance thereof.

                 SECTION 8.03  Governing Law.

                 This Supplemental Indenture and each Note shall be deemed to
be a contract under the laws of the State of New York, and for all purposes
shall be construed in accordance with the internal laws of such State, except
as may otherwise be required by mandatory provisions of law.  This Supplemental
Indenture is subject to the provisions of the Trust Indenture Act and shall, to
the extent applicable, be governed by such provisions.

                 SECTION 8.04  Counterparts.

                 This Supplemental Indenture may be executed in any number of
counterparts, each of which shall be an original, but all such counterparts
shall together constitute but one and the same instrument.

                 SECTION 8.05  Effect of Headings.  The Article and Section
headings herein and the Table of Contents are for convenience only and shall
not affect the construction hereof.

                     PROTECTION ONE ALARM MONITORING, INC.

              6 3/4% Convertible Senior Subordinated Note due 2003

                 This Note is one of a duly authorized issue of Securities of
the Issuer known as its 6 3/4% Convertible Senior Subordinated Notes due 2003
(herein referred to as the "Notes"), limited to the aggregate principal amount
of $90,000,000 (or $103,500,000 if the over- allotment option set forth in
Section 3 of the Underwriting Agreement dated September 16, 1996 (as amended
from time to time by the parties thereto) by and between the Issuer and the
Parent Company and Morgan Stanley & Co., Incorporated, Bear, Stearns & Co.,
Inc. and Montgomery Securities is exercised in full), all issued under and
pursuant to an Indenture, dated as of August 29, 1996 (herein referred to as
the "Subordinated Indenture"), between the Issuer, the Parent Company and State
Street Bank and Trust Company, a Massachusetts trust company, as trustee (the
"Trustee"), to which Subordinated Indenture and all indentures supplemental
thereto reference is hereby made for a description of the respective rights,
limitations of rights, obligations, duties and immunities thereunder of the
Issuer, the Parent Company, the Trustee and the Holders of the Notes.  This
Note is one of the series designated on the face hereof, and is issued pursuant
to an indenture supplemental to the Subordinated Indenture, dated as of
September 20, 1996, from the Issuer and the Parent Company to the Trustee,
relating to the Notes of this series (the "Supplemental Indenture").

                 In case an Event of Default, as defined in the Subordinated
Indenture, shall have occurred and be continuing, the principal of and accrued
interest on all Notes may be declared, and upon said declaration shall become,
due and payable, in the manner, with the effect and subject to the conditions
provided in the Subordinated Indenture.

                 The Subordinated Indenture and the Supplemental Indenture
contain provisions permitting the Issuer and the Trustee, with the consent of
the Holders of not less than a majority in aggregate principal amount of the
Notes at the time outstanding, evidenced as in the Subordinated Indenture
provided, to execute supplemental indentures adding any provisions to or
changing in any manner or eliminating any of the provisions of the Subordinated
Indenture, the Supplemental Indenture or of any other supplemental indenture or
modifying in any manner the rights of the Holders of the Notes; provided,
however, that no such supplemental indenture shall (i) extend the final
maturity of any Note, or reduce the principal amount thereof, or reduce the
rate or extend the time of payment of interest thereon, or reduce any amount
payable on redemption thereof, or make the principal thereof or interest or
premium, if any, thereon payable in any coin or currency other than that
provided in the Note, or impair or affect the right of any Noteholder to
institute suit for the payment thereof, or modify the provisions of the
Supplemental Indenture with respect to the subordination of the Notes in a
manner adverse to the Noteholders in any material respect, or change the
obligation of the Issuer to make redemption of any Note upon the happening of a
Fundamental Change in a manner adverse to the Holder of the Notes, or impair
the right to convert the Notes into Common Stock of the Parent Company subject
to the terms set forth in the Supplemental Indenture, including Article Four
thereof, without the consent of the Holder of each Note so affected or (ii)
reduce the aforesaid percentage of Notes, the Holders of which are required to
consent to any such supplemental indenture, without the consent of the Holders
of each Note then outstanding.  It is also provided in the Subordinated





<PAGE>   60
                                       2

Indenture that, prior to any declaration accelerating the maturity of the
Notes, the Holders of a majority in aggregate principal amount of the Notes at
the time outstanding may on behalf of the Holders of all of the Notes waive any
past Default or Event of Default under the Subordinated Indenture and its
consequences except a Default in respect of a covenant or provision of the
Subordinated Indenture or the Supplemental Indenture which cannot be modified
or amended without the consent of the Holder of each Note affected.  Any such
consent or waiver by the Holder of this Note (unless revoked as provided in the
Subordinated Indenture) shall be conclusive and binding upon such Holder and
upon all future Holders and owners of this Note and any Notes which may be
issued in exchange or substitute hereof, irrespective of whether or not any
notation thereof is made upon this Note or such other Notes.

                 The indebtedness evidenced by the Notes is, to the extent and
in the manner provided in the Supplemental Indenture, expressly subordinate and
subject in right of payment to the prior payment in full of all Senior
Indebtedness (as defined in the Supplemental Indenture) of the Issuer, whether
outstanding at the date of the Supplemental Indenture or thereafter incurred,
and this Note is issued subject to the provisions of the Supplemental Indenture
with respect to such subordination.  Each Holder of this Note, by accepting the
same, agrees to and shall be bound by such provisions and authorizes the
Trustee on its behalf to take such action as may be necessary or appropriate to
effectuate the subordination so provided and appoints the Trustee as such
Holder's attorney-in-fact for such purpose.

                 No reference herein to the Subordinated Indenture or to the
Supplemental Indenture and no provision of this Note or of the Subordinated
Indenture or of the Supplemental Indenture shall alter or impair the obligation
of the Issuer, which is absolute and unconditional, to pay the principal of and
any premium and interest on this Note at the place, at the respective times, at
the rate and in the coin or currency herein prescribed.  Interest on the Notes
shall be computed on the basis of a 360-day year comprised of twelve 30-day
months.

                 The Notes are issuable in registered form without coupons in
denominations of $1,000 and any integral multiple of $1,000.  At the office or
agency of the Issuer referred to on the face hereof, and in the manner and
subject to the limitations provided in the Subordinated Indenture, without
payment of any service charge but with payment of a sum sufficient to cover any
tax or other governmental charge that may be imposed in connection with any
registration, transfer or exchange of Notes, Notes may be exchanged for a like
aggregate principal amount of Notes of other authorized denominations.

                 The Notes will not be redeemable at the option of the Issuer
prior to September 19, 1999.  At any time on or after September 19, 1999, and
prior to maturity the Notes may be redeemed, subject to certain circumstances
specified in the Supplemental Indenture, at the option of the Issuer as a
whole, or from time to time in part, upon mailing a notice of such redemption
not less than 30 days before the date fixed for redemption to the Holders of
Notes at their last registered addresses, all as provided in the Supplemental
Indenture, at the following optional redemption prices (expressed as
percentages of the principal amount), together in each case with accrued
interest to, but excluding, the date fixed for redemption.

                 If redeemed during the 12-month period beginning September 15:

and 100% at September 15, 2003; provided that if the date fixed for redemption
is on March 15 or September 15, then the interest payable on such date shall be
paid to the Holder of record on the next preceding March 1 or September 1,
respectively.

 The Notes are not subject to redemption through the operation of any sinking
                                     fund.

                 If a Fundamental Change (as defined in the Supplemental
Indenture) occurs at any time prior to September 15, 2003, the Notes will be
redeemable on the 30th day after notice thereof at the option of the Holder.
Such payment shall be made at the following prices (expressed as percentages of
the principal amount) in the event of a Fundamental Change occurring during the
12-month period beginning September 15:

and 100% at September 15, 2003; provided in each case that if the Applicable
Price (as defined in the Supplemental Indenture) is less than the Reference
Market Price (as defined in the Supplemental Indenture), the Issuer shall
redeem such Notes at a price equal to the foregoing repayment price multiplied
by the fraction obtained by dividing the Applicable Price by the Reference
Market Price.  In each case, the Issuer shall also pay accrued interest, if
any, on such Notes to, but excluding, the repayment date; provided that if such
repayment date is March 15 or September 15, then the interest payable on such
date shall be paid to the Holder of record of the Note on the next preceding
March 1 or September 1.  The Issuer shall mail to all Holders of record of the
Notes a notice of the occurrence of a Fundamental Change and of the redemption
right arising as a result thereof on or before the 10th day after the
occurrence of such Fundamental Change.  For a Note to be so repaid at the
option of the Holder, the Issuer must receive at the office or agency of the
Issuer maintained for that purpose in accordance with the terms of the
Indenture, such Note with the form entitled "Option to Elect Repayment Upon a
Fundamental Change" on the reverse thereof duly completed, together with such
Notes duly endorsed for transfer, on or before the 30th day after the date of
such notice (or if such 30th day is not a Business Day, the immediately
preceding Business Day).

                 Subject to the provisions of the Supplemental Indenture, the
Holder hereof has the right, at its option, at any time after 90 days following
the latest date of original issuance of the Notes and prior to the close of
business on September 15, 2003, or, as to all or any portion





<PAGE>   62
                                       4

hereof called for redemption, prior to the close of business on the Business
Day immediately preceding the date fixed for redemption (unless the Issuer
shall default in payment due upon redemption thereof), to convert the principal
hereof or any portion of such principal which is $1,000 or an integral multiple
thereof, into that number of shares of Common Stock of the Parent Company, as
said shares shall be constituted at the date of conversion, obtained by
dividing the principal amount of this Note or portion thereof to be converted
by the Conversion Price of $17.95 or such Conversion Price as adjusted from
time to time as provided in the Supplemental Indenture, upon surrender of this
Note, together with the form entitled "Conversion Notice" on the reverse
thereof duly completed, as provided in the Supplemental Indenture, to the
Parent Company at the office or agency of the Parent Company maintained for
that purpose in accordance with the terms of the Supplemental Indenture, or at
the option of such Holder, the Corporate Trust Office, and, unless the shares
issuable on conversion are to be issued in the same name as this Note, duly
endorsed by, or accompanied by instruments of transfer in form satisfactory to
the Parent Company duly executed by, the Holder or by such Holder's duly
authorized attorney.  No adjustment in respect of interest or dividends will be
made upon any conversion; provided, however, that if this Note shall be
surrendered for conversion during the period from the close of business on any
record date for the payment of interest to the close of business on the
Business Day preceding the interest payment date, this Note (unless it or the
portion being converted shall have been called for redemption during the period
from the close of business on any record date for the payment of interest to
the close of business on the Business Day preceding the interest payment date)
must be accompanied by an amount, in New York Clearing House funds or other
funds acceptable to the Parent Company, equal to the interest payable on such
interest payment date on the principal amount being converted.  No fractional
shares will be issued upon any conversion, but an adjustment in cash will be
made, as provided in the Indenture, in respect of any fraction of a share which
would otherwise be issuable upon the surrender of any Note or Notes for
conversion.

                 Any Notes called for redemption, unless surrendered for
conversion on or before the close of business on the date fixed for redemption,
may be deemed to be purchased from the Holder of such Notes at an amount equal
to the applicable redemption price, together with accrued interest to (but
excluding) the date fixed for redemption, by one or more investment bankers or
other purchasers who may agree with the Issuer to purchase such Notes from the
Holders thereof and convert them into Common Stock of the Parent Company and to
make payment for such Notes as aforesaid to the Trustee in trust for such
Holders.

                 Upon due presentment for registration of transfer of this Note
at the office or agency of the Issuer maintained for that purpose in accordance
with the terms of the Subordinated Indenture, or at the option of the Holder of
this Note, at the Corporate Trust Office, a new Note or Notes of authorized
denominations for an equal aggregate principal amount will be issued to the
transferee in exchange thereof, subject to the limitations provided in the
Indenture, without charge except for any tax or other governmental charge
imposed in connection therewith.

                 The Issuer, the Parent Company, the Trustee, any
authenticating agent, any paying agent, any conversion agent and any Note
registrar may deem and treat the registered Holder hereof as the absolute owner
of this Note (whether or not this Note shall be overdue and





<PAGE>   63
                                       5

notwithstanding any notation of ownership or other writing hereon made by
anyone other than the Issuer or any Note registrar), for the purpose of
receiving payment hereof, or on account hereof, for the conversion hereof and
for all other purposes, and neither the Issuer nor the Parent Company nor the
Trustee nor any other authenticating agent nor any paying agent nor any other
conversion agent nor any Note registrar shall be affected by any notice to the
contrary.  All payments made to or upon the order of such registered Holder
shall, to the extent of the sum or sums paid, satisfy and discharge liability
for monies payable on this Note.

                 No recourse for the payment of the principal of or any premium
or interest on this Note, or for any claim based hereon or otherwise in respect
hereof, and no recourse under or upon any obligation, covenant or agreement of
the Issuer in the Indenture or any indenture supplemental thereto or in any
Note, or because of the creation of any indebtedness represented thereby, shall
be had against any incorporator, stockholder, employee, agent, officer or
director or subsidiary, as such, past, present or future, of the Issuer or the
Parent Company or of any successor corporation thereto, either directly or
through the Issuer or the Parent Company or any successor corporation, whether
by virtue of any constitution, statute or rule of law or by the enforcement of
any assessment or penalty or otherwise, all such liability being, by the
acceptance hereof and as part of the consideration for the issue hereof,
expressly waived and released.

                 The Issuer's obligations under the Notes are guaranteed on a
senior subordinated basis, jointly and severally, by the Parent Company and by
each Subsidiary of Parent Company which becomes a Guarantor pursuant to the
provisions of the Subordinated Indenture.

                 Terms used in this Note and defined in the Subordinated
Indenture or the Supplemental Indenture, as the case may be, are used herein as
therein defined.

         6.      Representations and Warranties.

                          (a)     Authorization.  The execution, delivery and
         performance of each of the Refinancing Transactions Documents and the
         consummation of the Refinancing Transactions by each Loan Party have
         been duly authorized by all necessary corporate and shareholder
         action.

                          (b)     No Conflict.  The execution, delivery and
         performance by each Loan Party of each Refinancing Transactions
         Document to which it is a party do not and will not: (1) violate any
         provision of law applicable to any Loan Party, the certificate of
         incorporation or bylaws of any Loan Party, or any order, judgment or
         decree of any court or other agency of government binding on any Loan
         Party; (2) conflict with, result in a breach of or constitute (with
         due notice or lapse of time or both) a default under any Contractual
         Obligation of any Loan Party; (3) result in or require the creation or
         imposition of any material Lien upon any of the properties or assets
         of any Loan Party (other than Liens in favor of Agent, for the benefit
         of Lenders); or (y) require any approval or consent of any Person
         under any Contractual Obligation of any Loan Party, except, with
         respect to each of the clauses (1) through (4) above for such
         approvals or consents to be obtained on or before the First Amendment
         Effective Date.

                          (c)     Binding Obligation.  This Agreement is, and
         the other Refinancing Transactions Documents, when executed and
         delivered will be, the legally valid and binding obligations of the
         applicable Loan Parties, each enforceable against the Loan Parties in
         accordance with their respective terms.

                          (d)     Valid Issuance of Subordinated Convertible
         Notes.  The issuance and sale of the Subordinated Convertible Notes
         are registered and/or qualified under applicable federal and state
         securities laws.  Borrower has the corporate power and authority to
         incur the Indebtedness evidenced by the Subordinated Convertible Notes
         and to issue the Subordinated Convertible Notes.  Holdings has the
         corporate power and authority to incur the Contingent Obligations
         evidenced by the Subordinated Convertible Note Indenture and to issue
         the Holdings Capital Stock issuable upon conversion of the
         Subordinated Convertible Notes.  The Subordinated Convertible Notes,
         when issued and paid for, will be the legally valid and binding
         obligations of Borrower enforceable against Borrower in accordance
         with their terms (including those pertaining to subordination).  On or
         prior to the First Amendment Effective Date, Borrower shall have
         delivered to Agent and each of the Lenders complete and correct copies
         of the Subordinated Convertible Note Underwriting Agreement, the

         Convertible Note Documents as may have been requested by Agent and
         each of the representations and warranties given by Holdings, Borrower
         or Borrower's Subsidiaries therein shall be true and correct in all
         material respects as of the First Amendment Effective Date.  The
         subordination provisions of the Subordinated Convertible Note
         Documents will be enforceable against the holders of the Subordinated
         Convertible Notes by the holder of any Notes which has not effectively
         waived the benefits thereof.  All obligations, including the
         Obligations to pay principal of and interest on the Loans, constitute
         senior Indebtedness entitled to the benefits





                                       8
<PAGE>   9
         of the subordination created by the Subordinated Convertible Note
         Documents.  Borrower acknowledges that Agent and each Lender are
         entering into this Amendment and/or each Lender Addition Agreement and
         are extending the Revolving Loan Commitment in reliance upon the
         subordination provisions of the Subordinated Convertible Note
         Documents and this Section.

         7.      Miscellaneous.

                          (a)     Captions.  Section captions used in this
         Amendment are for convenience only, and shall not affect the
         construction of this Amendment.

                          (b)     Governing Law.  This Amendment shall be a
         contract made under and governed by the laws of the State of Illinois,
         without regard to conflict of laws principles.  Whenever possible each
         provision of this Amendment shall be interpreted in such manner as to
         be effective and valid under applicable law, but if any provision of
         this Amendment shall be prohibited by or invalid under such law, such
         provision shall be ineffective to the extent of such prohibition or
         invalidity, without invalidating the remainder of such provision or
         the remaining provisions of this Amendment.

                          (c)     Counterparts.  This Amendment may be executed
         in any number of counterparts and by the different parties on separate
         counterparts, and each such counterpart shall be deemed to be an
         original, but all such counterparts shall together constitute but one
         and the same Amendment.

                          (d)     Successors and Assigns.  This Amendment shall
         be binding upon Borrower, Agent and Lenders and their respective
         successors and assigns, and shall inure to the sole benefit of
         Borrower, Agent and Lenders and their respective successors and
         assigns.

                          (e)     References.  Any reference to the Credit
         Agreement contained in any notice, request, certificate, or other
         document executed concurrently with or after the execution and
         delivery of this Amendment shall be deemed to include this Amendment
         unless the context shall otherwise require.

                          (f)     Continued Effectiveness.  Notwithstanding
         anything contained herein, the terms of this Amendment are not
         intended to and do not service to effect a novation as to the Credit
         Agreement.  The parties hereto expressly do not intend to extinguish
         the Credit Agreement.  Instead, it is the express intention of the
         parties hereto to reaffirm the indebtedness created under the Credit
         Agreement which is evidenced by the Revolving Notes and secured by the
         Collateral.  The Credit Agreement as amended hereby and each of the
         Loan Documents remain in full force and effect.

                          (g)     Costs, Expenses and Taxes.  Borrower affirms
         and acknowledges that Section 10.1 of the Credit Agreement applies to
         this Amendment and the transactions and agreements and documents
         contemplated hereunder.

                 Delivered at Chicago, Illinois, as of the date and year first

       CAUTIONARY STATEMENT FOR PURPOSES OF THE "SAFE HARBOR" PROVISIONS
            OF THE PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995

         Protection One, Inc. ("POI"), its subsidiary Protection One Alarm
Monitoring, Inc. ("Monitoring") and Monitoring's subsidiaries (collectively the
"Company"), and their respective affiliates, from time to time issue written
and/or oral statements that may contain froward- looking information, including
projections, estimates, forecasts, plans and objectives.  The Company wishes to
ensure that any and all forward looking statements are accompanied by meaningful
cautionary statements in order to maximize to the fullest extent possible the
protections of the "safe harbor" provisions of the Private Securities Litigation
Reform Act of 1995 (the "Act"), as set forth in Section 27A of the Securities
Act of 1933, as amended (the "Securities Act"), and Section 21E of the
Securities Exchange Act of 1934, as amended.  Accordingly, each such
forward-looking statement is qualified in its entirety by reference to, and is
accompanied by, the risk factors described below, which could cause the
Company's future results and stockholder values to differ materially from those
expressed in such statement.

         Any forward looking statement made by or on behalf of the Company
speaks only as of the date on which such statement is made, and the Company
undertakes no obligation to update any forward looking statement to reflect
events or circumstances after the date on which such statement is made or to

such factor on the business or the extent to which any factor, or combination
of factors, may cause actual results to differ materially from those contained
in any forward looking statement.  Therefore, forward looking statements should
not be relied upon as guarantees or predictions of actual future performance or
results.

         Risks Related to High Leverage.  The Company is highly leveraged.  At
June 30, 1996, the Company's consolidated indebtedness was $207.1 million, and
Monitoring had unused borrowing capacity under its revolving credit facility
(the "Revolving Credit Facility") of $19.1 million.  (POI is a holding company
with no operations of its own and no significant assets other than POI's
ownership of the capital stock of Monitoring.)  As of June 30, 1996, after
giving effect to the offering and sale of $103.5 million aggregate principal
amount of Monitoring's 6-3/4% Convertible Senior Subordinated Notes due 2003
(the "Convertible Notes") that were issued on September 20, 1996 and (pursuant
to the exercise in full of the underwriters' over-allotment option) on October
11, 1996, and the application of the net proceeds thereof, the Company's
consolidated indebtedness would have been $229.6 million (excluding $1.2
million of contingent reimbursement obligations under outstanding letters of
credit), and Monitoring would have had unused borrowing capacity under the
Revolving Credit Facility of $100.0 million.  Future additions of subscriber
accounts through the purchases from Company's independent dealers (the "Dealer
Program") and acquisitions of subscriber account portfolios will require
additional borrowings under Monitoring's revolving credit facility (the
Revolving Credit Facility), thereby further increasing the Company's
leverage.  See "Risks Related to Acquisitions." All borrowings then outstanding
under the Revolving Credit Facility are currently due in full on January 3,
2000.  Although Monitoring believes that it will be able to obtain further
extensions of the maturity date of the Revolving Credit Facility from time to
time, or will be able to refinance the Revolving Credit Facility prior to its
present maturity date, there can be no assurance that Monitoring will be able
to do so.  Monitoring will be required to make semiannual cash payments of
interest on the Convertible Notes of $3.5 million beginning March 15, 1997; in
addition, the principal amount of Monitoring's 13-5/8% Senior Subordinated
Discount Notes due 2005 (the "Discount Notes") will accrete in value until June
30, 1998, and Monitoring will be required to make cash payments of interest on
the Discount Notes beginning on December 31, 1998.  Based on the Discount
Notes' interest rate of 13-5/8%, such interest payment will be $11.3 million
<PAGE>   2
semiannually, or $22.6 million per year.  There can be no assurance that
Monitoring's cash flows from operations will be sufficient to make the required
interest payments on the Convertible Notes, the Discount Notes and borrowings
under the Revolving Credit Facility.

         The indentures pursuant to which the Convertible Notes and the
Discount Notes were issued (the "Convertible Notes Indenture" and the "Discount
Notes Indenture," respectively ) do not provide for any current amortization of
principal or require the establishment of any reserves or sinking funds in
respect of the payment of principal.  As a result, Monitoring will be required
to repay the full principal amount of the Convertible Notes ($103.5 million) on
September 15, 2003 and the full principal amount of the Discount Notes ($166.0
million) on June 30, 2005.  There can be no assurance that Monitoring will have
the cash necessary to repay the Convertible Notes and the Discount Notes at
maturity or will be able to refinance such obligations.

         Monitoring's ability to pay the principal of and interest on the
Convertible Notes and the Discount Notes and continue to service its other
indebtedness will be subject to various business, financial and other factors,
many of which are beyond the Company's control.  In addition, each of the
Discount Notes Indenture, the agreement governing the Revolving Credit Facility
(the "Credit Agreement") and, to a lesser extent, the Convertible Notes
Indenture includes covenants that restrict the operational and financial
flexibility of the Company.  Failure to comply with certain covenants would, in
some instances, permit the holders of the Convertible Notes or the Discount
Notes or the lenders under the Revolving Credit Facility to accelerate the
maturity of Monitoring's obligations thereunder, and in other instances could
result in cross-defaults permitting the acceleration of all such debt and debt
under other agreements.

         The Company's high degree of leverage may have important consequences,
including the following: (i) a substantial portion of the Company's cash flow
from operations is, and will continue to be, dedicated to the payment of the
principal of and interest on the Company's indebtedness, thereby, reducing the
funds available to the Company for its operations and future growth or other
business opportunities; (ii) the Company's ability to obtain additional
financing in the future for working capital, the Dealer Program, acquisitions
of portfolios of subscriber accounts, capital expenditures, general corporate
purposes or other purposes may be impaired; (iii) the Convertible Notes
Indenture, the Discount Notes Indenture and the Credit Agreement contain, and
are expected to continue to contain, certain restrictive covenants, including
certain covenants that require the Company to obtain the consent of the lenders
under the Revolving Credit Facility and to maintain certain financial ratios in
order to undertake significant acquisitions of portfolios of subscriber
accounts; (iv) Monitoring's borrowings under the Revolving Credit Facility are
at floating rates of interest, causing the Company to be vulnerable to
increases in interest rates; (v) the Company will be more vulnerable to a
downturn in the Company's business or the economy generally; and (vi) the
Company's ability to compete against other less leveraged companies may be
adversely affected.

         Risks Related to Acquisitions.  A principal element of the Company's
business strategy is to acquire portfolios of alarm monitoring accounts.
During the fiscal 1992-1995 period, the Company completed 87 acquisitions of
the portfolios of subscriber accounts of other alarm service companies, and
those acquisitions were the primary source of the Company's growth during that
period.  Although the Dealer Program is anticipated to be an increasingly
important component of the Company's growth, an additional 27 portfolios of
subscriber accounts were acquired during the first nine months of fiscal 1996,
and acquisitions of portfolios of subscriber accounts are expected to continue.
The Company faces competition for the acquisition of portfolios of subscriber
accounts, and may be required to offer higher prices for acquired accounts than
the Company has in the past.  See "Competition." In addition, due to the
continuing consolidation of the security alarm industry and the acquisition by
the Company and other alarm companies of a number of large portfolios of
subscriber accounts, there may in the future be fewer large portfolios of
subscriber accounts available for acquisition.  There can be no assurance that
the Company will be able to find acceptable acquisition candidates or, if such
candidates are identified, that acquisitions can be consummated on terms
acceptable to the Company.

         Acquisitions of portfolios of subscriber accounts involve a number of
special risks, including the possibility of unanticipated problems not
discovered prior to the acquisition, account attrition and the diversion





                                       2
<PAGE>   3
of management's attention from other business activities in order to focus on
the assimilation of accounts.  For acquisitions that are structured as the
purchase of the stock of other alarm companies, the Company may assume
unexpected liabilities and must dispose of the unnecessary assets of the
acquired companies.

         Because the Company's primary consideration in acquiring a portfolio
of subscriber accounts is the amount of cash flow that can be derived from the
monthly recurring revenue ("MRR") associated with the purchased accounts, the
price paid by the Company is customarily directly tied to such MRR.  The price
paid varies based on the number and quality of accounts being purchased from
the seller, the historical activity of such accounts and other factors.  The
seller typically does not have audited historical financial information with
respect to the acquired accounts; thus, in making acquisitions the Company
generally has relied on management's knowledge of the industry, due diligence
procedures and representations and warranties of the sellers.  There can be no
assurance that such representations and warranties are true and complete or, if
such representations and warranties are inaccurate, that the Company will be
able to recover damages from the seller in an amount sufficient to fully
compensate the Company for any resulting losses.  The Company expects that
future acquisitions will present at least the same risks to the Company as its
prior acquisitions.

         An important aspect of the Company's acquisition program is the
assimilation of subscriber accounts into the Company's operations after
purchase.  Depending on the size, frequency and location of acquisitions, the
assimilation of subscribers may adversely affect the provision of field repair
services to existing subscribers, which may cause subscriber attrition to
increase.  In addition, if the Company's corporate or branch operations fail to
assimilate a substantial portion of acquired subscriber accounts, the Company
may experience higher attrition in the future.

         History of Losses.  The Company incurred losses attributable to common
stock of $11.3 million for the nine months ended June 30, 1996, $18.5 million
for fiscal 1995, $9.2 million for fiscal 1994, $4.6 million for fiscal 1993 and
$5.0 million for fiscal 1992. ("Losses attributable to common stock" means the
Company's net loss, less dividends payable on preferred stock.)  These losses
reflect, among other factors, the substantial charges incurred by the Company
for amortization of purchased subscriber accounts, interest incurred on the
Company's indebtedness and extraordinary losses on early extinguishment of
debt.  Such charges, with the exception of the extraordinary losses, will
increase as the Company continues to purchase subscriber accounts, if the
Company's indebtedness increases, or if interest rates increase.  The Company's
earnings have been insufficient to cover its fixed charges since the Company
was formed, and there can be no assurance that the Company will attain
profitable operations.

         Risks Related to the Dealer Program.  During fiscal 1995 and the first
nine months of fiscal 1996, the Company increased its emphasis on the Dealer
Program, which became a more significant source of growth than in prior years.
The Company expects that this emphasis will continue.  Several of the Company's
competitors also have dealer programs, and there can be no assurance that the
Company will be able to retain or expand its current dealer base or that
competitive offers to the Company's dealers will not require the Company to pay
higher prices to the Company's dealers for subscriber accounts than previously
paid.  The Company's five highest producing dealers generated 47.0% of the
total subscriber accounts purchased by the Company through the Dealer Program
in the first nine months of fiscal 1996.  The loss of any of such dealers would
negatively impact the Company's subscribers, revenues and cash flows from
operations.

         Need for Additional Capital.  In fiscal 1995 and the first nine months
of fiscal 1996, the Company invested a total of $138.9 million in acquisitions
of portfolios of subscriber accounts and purchases of subscriber accounts
through the Dealer Program.  Net cash provided by operating activities totaled
$25.1 million during such period, and the Company used borrowings under the
Revolving Credit Facility and proceeds from offerings of debt and equity
securities to fund the remainder of the Company's investing activities.  The
Company intends to continue to pursue subscriber account growth through the
Dealer Program and acquisitions.  As a result, the Company will be required to
seek additional funding from additional borrowing under the Revolving Credit
Facility and the sale of additional securities in the future, which may lead to
higher leverage or the dilution of then existing holders' investment in the
equity of POI.  See "Risks Related to High Leverage." Any inability of the
Company to obtain funding through external financings is likely to adversely
affect the Company's ability to increase its subscribers, revenues and cash
flows from operations.  There can





                                       3
<PAGE>   4
be no assurance that external funding will be available to the Company on
attractive terms or at all.

         Management of Growth.  The Company's business strategy is to grow
rapidly through the addition of subscriber accounts.  This expansion has placed
and will continue to place substantial demands on the Company's management and
operational resources and system of financial and internal controls.  The
Company's future operating results will depend in part on the Company's ability
to continue to implement and improve the Company's operating and financial
controls and to expand, train and manage the Company's employee base.
Significant changes in quarterly revenues and costs may result from the
Company's execution of its business strategy, resulting in fluctuating
financial results.  Additionally, management of growth may limit the time
available to the Company's management to attend to other operational, financial
and strategic issues.

         Attrition of Subscriber Accounts.  The Company experiences attrition
of subscriber accounts as a result of, among other factors, relocation of
subscribers, adverse financial and economic conditions, and competition from
other alarm service companies.  In addition, the Company loses certain
accounts, particularly acquired accounts, to the extent the Company does not
service those accounts adequately or does not assimilate new accounts into the
Company's operations.  An increase in such attrition could have a material
adverse effect on the Company's revenues and earnings.

         When acquiring accounts, the Company seeks to withhold a portion of
the purchase price as a partial reserve against excess subscriber attrition.
If the actual attrition rate for the accounts acquired is greater than the rate
assumed by the Company at the time of the acquisition, and the Company is
unable to recoup its damages from the portion of the purchase price held back
from the seller, such attrition could have a material adverse effect on the
Company's financial condition or results of operations.  There can be no
assurance that the Company will be able to obtain purchase price holdbacks in
future acquisitions, particularly acquisitions of large portfolios.  The
Company is not aware of any reliable historical data relating to account
attrition rates prepared by companies from whom the Company has acquired
accounts, and the Company has no assurance that actual account attrition for
acquired accounts will not be greater than the attrition rate assumed or
historically incurred by the Company.  In addition, because some acquired
accounts are prepaid on an annual, semiannual or quarterly basis, attrition may
not become evident for some time after an acquisition is consummated.

         At June 30, 1996, the cost of subscriber accounts and intangible
assets, net of previously accumulated amortization, was $238.9 million, which
constituted 87.1% of the book value of the Company's total assets.  The
Company's purchased subscriber accounts are amortized on a straight-line basis
over the estimated life of the related revenues.  To estimate such life, the
Company first determines gross subscriber attrition, defined by the Company for
a period as a quotient, the numerator of which is equal to the number of
subscribers who disconnect services during such period and the denominator of
which is the average of the number of subscribers at each month end during such
period.  Gross subscriber attrition was 18.6% and 19.9% for the twelve months
ended June 30, 1995 and 1996, respectively.  The Company offsets gross
attrition by adding new accounts from subscribers who move into premises
previously occupied by Company subscribers and in which security alarm systems
are installed, conversions of accounts that were previously monitored by other
alarm companies to the Company's monitoring services and accounts for which the
Company obtains a guarantee from the seller that provides for the Company to
"put" back to the seller canceled accounts.  The resulting figure is used as a
guideline to determine the estimated life of subscriber revenues.  It is the
Company's policy to review periodically actual account attrition and, when
necessary, adjust the remaining estimated lives of the Company's purchased
accounts to reflect assumed future attrition.  In fiscal 1993, the Company made
such an adjustment to the estimated life of subscriber accounts, reducing such
estimated life from 12 years to 10 years.  There could be a material adverse
effect on the Company's results of operations and financial condition if actual
account attrition significantly exceeds assumed attrition and the Company has
to make further adjustments with respect to the amortization of purchased
subscriber accounts.

         Impact of Accounting Differences for Account Purchases and New
Installations.  A difference between the accounting treatment of the purchase
of subscriber accounts (including both purchases of subscriber account
portfolios and purchases under ongoing agreements with independent alarm
dealers) and the accounting treatment of the generation of subscriber accounts
through direct sales by the Company's sales





                                       4
<PAGE>   5
force has a significant impact on the Company's results of operations.  All
direct external costs associated with purchases of subscriber accounts are
capitalized and amortized over 10 years on a straight-line basis.  Also
included in capitalized costs are certain acquisition transition costs that
reflect the Company's estimate of costs associated with incorporating the
purchased subscriber accounts into the Company's operations.  Such costs
include costs incurred by the Company in fulfilling the seller's
pre-acquisition obligations to the acquired subscribers, such as providing
warranty repair services.  In contrast, all of the Company's costs related to
the marketing, sales and installation of new alarm monitoring systems generated
by the Company's sales force are expensed in the period in which such
activities occur.  The Company's marketing, sales and installation expenses for
new systems generally exceed installation revenues.

         The Company's purchase activity increased significantly during fiscal
1994, fiscal 1995 and the first nine months of fiscal 1996.  See "Risks Related
to Acquisitions." In addition, during those periods the Company reduced the
Company's sales of new systems and related marketing expenditures.  As a result
of the difference in the methods by which such activities are accounted for,
the combined effect of these two factors was to improve operating results
during fiscal 1994, fiscal 1995 and the first nine months of fiscal 1996.  The
Company does not expect to further reduce sales of new systems by Company
personnel and related marketing expenditures in the remainder of fiscal 1996 or
in fiscal 1997.  There can be no assurance that the Company will not increase
its emphasis on the marketing and sales of new alarm system installations in
the future, particularly in connection with a joint venture or other strategic
alliance; any such increase could adversely affect results of operations.  The
Company anticipates that subscriber accounts added through the co-branded
program with PacifiCorp will be purchased through the Dealer Program rather
than generated through sales of new alarm systems by Company personnel.

         Possible Adverse Effect of "False Alarm" Ordinances.  According to
certain data concerning the residential security alarm market prepared in
December 1995 by J.P. Freeman & Co., approximately 97% of alarm activations
that result in the dispatch of police or fire department personnel are not
emergencies, and thus are "false alarms." Significant concern has arisen in
certain municipalities about this high incidence of false alarms.  This concern
could cause a decrease in the likelihood or timeliness of police response to
alarm activations and thereby decrease the propensity of consumers to purchase
or maintain alarm monitoring services.

         A number of local governmental authorities have considered or adopted
various measures aimed at reducing the number of false alarms.  Such measures
include (i) subjecting alarm monitoring companies to fines or penalties for
transmitting false alarms, (ii) licensing individual alarm systems and the
revocation of such licenses following a specified number of false alarms, (iii)
imposing fines on alarm subscribers for false alarms, (iv) imposing limitations
on the number of times the police will respond to alarms at a particular
location after a specified number of false alarms, and (v) requiring further
verification of an alarm signal before the police will respond.  Enactment of
such measures could adversely affect the Company's future business and
operations.

         Possible Adverse Effect of Future Government Regulations; Risks of
Litigation.  The Company's operations are subject to a variety of laws,
regulations and licensing requirements of federal, state and local authorities.
In certain jurisdictions, the Company is required to obtain licenses or
permits, to comply with standards governing employee selection and training,
and to meet certain standards in the conduct of the Company's business.  The
loss of such licenses, or the imposition of conditions to the granting or
retention of such licenses, could have a material adverse effect on the
Company.

         The Company's advertising and sales practices are regulated by both
the Federal Trade Commission and state consumer protection laws.  Such
regulations include restrictions on the manner in which the Company promotes
the sale of security alarm systems and the obligation of the Company to provide
purchasers of alarm systems with certain rescission rights.  Although the
Company believes that it has complied with these regulations in all material
respects, there can be no assurance that none of these regulations was violated
in connection with the solicitation of the Company's existing subscriber
accounts, particularly with respect to accounts acquired from third parties, or
that no such violation will occur in the future.





                                       5
<PAGE>   6
         From time to time, subscribers have submitted complaints to state and
local authorities regarding the Company's sales and billing practices, which in
some instances have resulted in discussions with, or actions by, such
authorities.  In August 1994, as a result of certain complaints by subscribers,
three California governmental authorities brought an action against the
Company, and concurrently settled such action.  In connection with the
settlement of such action, the Company agreed to the filing of an injunction
requiring the Company to provide notices of certain increases in charges for
its services and to comply with certain restrictions in its marketing, billing
and collection activities, and paid restitution to subscribers in the amount of
$31,000 and civil penalties of $30,000.  Any violation by the Company of the
terms of such injunction could have a material adverse effect on the Company.

         The Company does not believe that any of the investigations or actions
described herein has had or will have a material adverse effect on the Company.
However, there can be no assurance that other actions that may be taken in the
future by these or other authorities as a result of subscriber complaints will
not have such adverse effect on the Company.

         Risks of Liability from Operations.  The nature of the services
provided by the Company potentially exposes it to greater risks of liability
for employee acts or omissions or system failure than may be inherent in other
businesses.  Most of the Company's alarm monitoring agreements and other
agreements pursuant to which the Company sells its products and services
contain provisions limiting liability to subscribers in an attempt to reduce
this risk.  However, in the event of litigation with respect to such matters
there can be no assurance that these limitations will be enforced, and the
costs of such litigation could have an adverse effect on the Company.

         The Company's alarm response and patrol services require Company
personnel to respond to emergencies that may entail risk of harm to such
employees and to others.  In most cities in which the Company provides such
services, the Company's patrol officers carry firearms, which may increase such
risk.  Although the Company screens and trains its employees, the provision of
alarm response service subjects the Company to greater risks related to
accidents or employee behavior than other types of businesses.  Reduction of
police participation in the handling of emergencies could expose the Company's
patrol officers to greater hazards and further increase the Company's risk of
liability.

         The Company carries insurance of various types, including general
liability and errors and omissions insurance providing coverage of $15.0
million on both an aggregate and a per claim basis.  The loss experience of the
Company and other security service companies may affect the availability and
cost of such insurance.  Certain of the Company's insurance policies and the
laws of some states may limit or prohibit insurance coverage for punitive or
certain other types of damages, or liability arising from gross negligence.

         Geographic Concentration.  The Company's existing subscriber base is
geographically concentrated in certain metropolitan areas and surrounding
suburbs in the seven western states in which the Company operates.
Accordingly, the performance of the Company may be adversely affected by
regional or local economic conditions.

         As a result of acquisitions or strategic alliances, the Company may
from time to time expand its operations into regions outside of the Company's
current operating area.  The acquisition of subscriber accounts in other
regions, or in metropolitan areas in which the Company does not currently have
subscribers, requires an investment by the Company in local branches and
personnel necessary to service such accounts.  In order for the Company to
expand successfully into a new area, the Company must obtain a sufficient
number, and density, of subscriber accounts in such area to support the
additional investment.  There can be no assurance that an expansion into new
geographic areas would generate operating profits.

         Competition.  The security alarm industry is highly competitive and
highly fragmented.  The Company competes with larger national companies, as
well as smaller regional and local companies, in all of the Company's
operations.  Furthermore, new competitors are continuing to enter the industry
and the Company may encounter additional competition from such future industry
entrants.





                                       6
<PAGE>   7
         Certain of the Company's current competitors have, and new competitors
may have, greater financial resources than the Company.  In addition, other
alarm services companies have adopted a strategy similar to the Company's that
entails the aggressive purchase of alarm monitoring accounts both through
acquisitions of account portfolios and through dealer programs.  Some of these
companies may be willing to offer higher prices than the Company is prepared to
offer to purchase subscriber accounts.  The effect of such competition may be
to reduce the purchase opportunities available to the Company, thus reducing
the Company's rate of growth, or to increase the price paid by the Company for
subscriber accounts, which would adversely affect the Company's return on
investment in such accounts and the Company's results of operations.

         Dependence Upon Senior Management.  The success of the Company's
business is largely dependent upon the active participation of the Company's
executive officers.  The loss of the services of one or more of such officers
for any reason may have a material adverse effect on the Company's business.

         Effect of Change of Control and Fundamental Change.  At the option of
the holders of the Convertible Notes, Monitoring is required to purchase the
Convertible Notes at a price initially equal to 106.75% of the principal amount
thereof plus accrued and unpaid interest upon the occurrence of any
"Fundamental Change" as defined in the Convertible Notes Indenture.  In
addition, Monitoring is required to make an offer to purchase all of the
Discount Notes at a price equal to 101% of their Accreted Value (as defined in
the Discount Notes Indenture) on any repurchase date prior to June 30, 1998, or
at a purchase price equal to 101% of the principal amount thereof plus accrued
and unpaid interest to any repurchase date on or after June 30, 1998, upon the
occurrence of any "Change of Control" as defined in the Discount Notes
Indenture.  A "Fundamental Change" and a "Change of Control" also constitute
events of default under the Revolving Credit Facility.  If such an event were
to occur, the Company may not be able to repay all of its obligations that
would then become payable.

         In addition to the factors described above, the following factors
should be considered carefully in evaluating an investment in the Common Stock,
par value $.01 per share, of POI (the "Common Stock"):

         Shares Eligible for Future Sale.   Of the 13,466,671 shares of Common
Stock outstanding at October 16, 1996, 9,799,610 shares were freely tradeable
in the public market without any restriction whatsoever, an additional
2,947,526 shares were eligible for sale subject to the volume limitations of
Rule 144 under the Securities Act, and 719,535 shares had been registered for
resale under the Securities Act.  In addition, as of October 16, 1996, (i) an
aggregate of 5,766,017 shares of Common Stock were issuable after December 19,
1996 upon conversion of the Convertible Notes at a conversion price of $17.95
per share, (ii) an aggregate of 1,351,158 shares of Common Stock were issuable
upon the exercise of outstanding warrants with a weighted average exercise
price of $3.19 per share, (iii) an aggregate of 1,272,060 shares of Common
Stock were issuable upon the exercise of outstanding options and management
performance warrants with a weighted average exercise price of $5.79 per share,
and (iv) an aggregate of 34,265 shares were issuable in connection with certain
acquisitions of portfolios of alarm accounts, all of which shares are currently
registered for sale or resale under the Securities Act.  Certain stockholders
of the Company also have certain demand and "piggyback" registration rights
pursuant to a stockholder's agreement among such stockholders and POI.  Sales
and potential sales of substantial amounts of Common Stock in the public market
could adversely affect the prevailing market price of the Common Stock.

         Dividend Policy, Restrictions on Dividends.  POI has never paid any
cash dividends on the Common Stock and does not intend to pay any cash
dividends in the foreseeable future. POI is dependent upon the receipt of
dividends or other distributions from Monitoring to fund POI's operations, and
the Credit Agreement and the Discount Notes Indenture restrict POI's ability to
declare or pay any dividend on, or make any other distribution in respect of,
the Common Stock and do not permit distributions from Monitoring to POI other
than for certain specified purposes.

         Possible Volatility of Prices of the Common Stock.  The stock market
has from time to time experienced extreme price and volume fluctuations that
have been unrelated to the operating performance of particular companies.  The
market prices of the Common Stock may be significantly affected by quarterly
variations in the Company's operating results, litigation involving the
Company, general trends in the security





                                       7
<PAGE>   8
alarm industry, actions by governmental agencies, national economic and stock
market conditions, industry reports and other factors, many of which are beyond
the control of the Company.  Due to all of the foregoing factors, it is likely
that the Company's operating results will fall below the expectations of the
Company, securities analysts or investors in some future quarter.  In such
event, the trading price of the Common Stock would likely be materially and
adversely affected.

         Effect of Certain Changes and Delaware Anti-takeover Law on
Stockholder Values.  The provisions of the Convertible Notes and the Discount
Notes described above under "--Effect of Change of Control and Fundamental
Change", together with certain provisions of Delaware law, could delay or
prevent a change in control of the Company, could discourage acquisition
proposals and could diminish the opportunities for a stockholder to participate
in tender offers, including tender offers at a price above the then current
market value of the Common Stock or over a stockholder's cost basis in the
Common Stock.  In addition, the Board of Directors of POI, without further
stockholder approval, may issue preferred stock, which could have the effect of
delaying, deferring or preventing a change in control of POI.  The issuance of
