                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.   ACCOUNTING POLICIES

     Basis of Presentation
     ---------------------
     The accompanying unaudited consolidated financial statements of Guardian
     International, Inc. ("the Company") have been prepared pursuant to the
     rules and regulations of the Securities and Exchange Commission. In the
     opinion of management, the accompanying unaudited consolidated financial
     statements contain adjustments (consisting only of normal and recurring
     adjustments) necessary to present fairly the Company's financial position
     and the results of operations for the periods presented and the disclosures
     herein are adequate to make the information presented not misleading.
     Operating results for interim periods are not necessarily indicative of the
     results that can be expected for a full year. These interim financial
     statements should be read in conjunction with the Company's audited
     consolidated financial statements and notes thereto for the year ended
     December 31, 1999, included in the Company's Annual Report on Form 10-KSB.

     Revenue Recognition
     -------------------
     Installation Revenue. Prior to 1998, installation revenues were recognized
     when installations of security alarm systems were performed. Costs of
     providing installations were charged to income in the period when the
     installation occurred, except in cases where the Company maintained
     ownership of the equipment installed, in which case the Company capitalized
     the cost of the equipment to property and equipment and depreciated the
     amount over a seven year period. Net margins on installation activities
     prior to 1998 were not material to the Company's operations.

     In 1998, as a result of the acquisition of Mutual, the Company adopted a
     new accounting policy related to installation activity due to the nature of
     the high-end commercial installations performed by Mutual. The Company
     defers the excess of installation revenue over estimated selling costs and
     amortizes such difference over the initial term of the non-cancelable
     customer monitoring/service contract (generally over five years). Costs
     attributed to providing the installations, which include direct labor,
     direct materials and direct overhead, are capitalized and amortized over a
     five year period. All other costs associated with the installation are
     charged to income in the period when the installation occurs.

     Monitoring/Service Revenue. Customers are billed for monitoring and
     maintenance services primarily on a monthly or quarterly basis in advance
     of the period in which such services are provided. Unearned revenues result
     from billings in advance of performance of services. Contracts for
     monitoring services are generally for an initial non-cancelable term of
     three to five years with automatic renewal on an annual basis thereafter,
     unless terminated by either party. A substantial number of contracts are on
     an automatic renewal basis.

     Reclassification
     ----------------
     Certain 1999 amounts in the consolidated financial statements have been
     reclassified to conform to the 2000 presentation.

2.   PROPERTY AND EQUIPMENT, NET

     During the three months ended March 31, 2000, the Company expended
     approximately $378,000 for the purchase of fixed assets, including
     subscriber premises equipment approximating $253,000.

     Under the Renewed Credit Facility, borrowings bear interest at floating
     rates, either at Prime plus 1 3/4% or, at the Company's election, LIBOR
     plus 3 1/2%. At March 31, 2000, the debt was bearing interest at varying
     rates. The Renewed Credit Facility expires in May 2001. Availability under
     the Renewed Credit Facility is subject to certain "Borrowing Base"
     limitations (as defined in the Renewed Credit Facility). The Renewed Credit
     Facility includes customary covenants, including, but not limited to,
     restrictions related to the incurrence of other debt, the encumbrance or
     sale of the Company's assets and the payment of dividends or making of
     other distributions to the Company's shareholders and other financial
     performance covenants. The Company believes it was in compliance with all
     such covenants as of March 31, 2000. At March 31, 2000, $5 million was
     available under the Renewed Credit Facility.

Item 2.  Management's Discussion and Analysis

Introductory Note

FORWARD-LOOKING STATEMENTS.

         In connection with the safe harbor provisions of the Private Securities
Litigation Reform Act of 1995, the Company is hereby providing cautionary
statements identifying important factors that could cause the Company's actual
results to differ materially from those projected in forward-looking statements
made herein. Any statements that express, or involve discussions as to,
expectations, beliefs, plans, objectives, assumptions or future events or
performance (often, but not always, identified through the use of words or
phrases such as the Company or management "believes," "expects," "anticipates,"
"hopes," words or phrases such as "will result," "are expected to," "will
continue," "is anticipated," "estimated," "projection" and "outlook," and words
of similar import) are not historical facts and may be forward-looking. Such
forward-looking statements involve risks and uncertainties, and, accordingly,
actual results could differ materially from those expressed in the
forward-looking statements. Information with respect to these risks and
uncertainties is included in the Company's Form 10-KSB for the fiscal year ended
December 31, 1999 filed with the Securities and Exchange Commission on March 30,
2000.

Overview

         The majority of the Company's revenue is derived from recurring
payments for the monitoring, maintenance and leasing of security and fire
systems, pursuant to contracts with initial terms typically ranging from one to
five years. The remainder of the Company's revenue is derived from the sale and
installation of security and fire systems and the servicing and upgrades of such
installed systems. Monitoring and service revenues are recognized as the service
is provided. On installations for which the Company retains title to the
electronic security systems, the excess of installation revenue over estimated
selling costs is amortized over the initial term of the related
service/monitoring contract (generally five years). All other installation
revenues are recognized in the period in which installation occurs. All direct
installation costs, which include materials, labor and installation overhead are
capitalized and amortized over a five year period. When the Company maintains
ownership of the equipment, the costs of such equipment are capitalized to
property and equipment and amortized over seven years.

         The Company has never had any net income and has a history of
consistent and sometimes significant net losses. The Company has two core
strategies: (1) generating monitoring contracts through its own sales and
installation efforts, and (2) acquiring alarm monitoring contracts. The Company
is exploring a third core strategy of direct investments in companies offering
related and unrelated technology and services. The first core strategy requires
a cost infrastructure that results in lower operating margins than are
achievable by companies that only acquire and service alarm monitoring
contracts. In order to pursue the second core strategy of acquiring alarm
monitoring contracts, the Company has chosen to issue yield-bearing instruments
(such as senior debt or preferred stock). The Company's present amortization
policy for those acquired contracts results in significant amortization costs.
The issuance of yield-bearing instruments results in related interest and
dividend expense. The Company believes that these strategies, which emphasize
creating long-term value over short-term net income, will result in the
Company's recording of net losses until such time as (i) the Company's cash flow
from its increased customer base allows it to reduce significantly its
indebtedness and related interest costs; and (ii) the Company's amortization
expense, through the passage of time and recognition of account losses, is
reduced.

                                       8
<PAGE>

         Alarm monitoring revenues generate favorable gross margins.
Historically, installation and service activity generated unfavorable gross
margins because such activity was necessary for the generation and retention of
residential and mid-market commercial alarm monitoring customers. With the
February 1998 acquisition of Mutual Central Alarm Services, Inc. ("Mutual"), a
New York City-based provider to high-end commercial customers, however,
approximately 40% of the Company's installation activity now generates favorable
gross margins because competition in the high-end commercial market is based
less on price and more on the ability of competitors to design, deliver and
maintain sophisticated security systems.

         The Company's objective is to provide residential and commercial
security services to an increasing number of subscribers. The Company's growth
strategy is to enhance its position in the security alarm monitoring industry in
Florida and in the Metropolitan New York City area by increasing the number and
density of subscribers for whom it provides services. The Company is pursuing
this strategy through a growth plan involving incorporating acquisitions of
portfolios of subscriber accounts in existing and contiguous markets and growth
in the Company's existing markets through referrals and traditional local
marketing. The Company believes that increasing the number and density of its
subscribers will help it to achieve economies of scale and enhance its results
of operations. The Company also regularly reviews opportunities for expanding
its operations into other large metropolitan markets.

Key Operating Measures

         The Company believes that EBITDA, MRR, and MRR attrition are key
measurements of performance in the security monitoring industry.

         EBITDA. Earnings before interest, taxes, depreciation and amortization
("EBITDA") does not represent cash flow from operations as defined by generally
accepted accounting principles, should not be construed as an alternative to
operating income and is indicative neither of operating performance nor of cash
flows available to fund the cash needs of the Company. Items excluded from
EBITDA are significant components in understanding and assessing the financial
performance of the Company. The Company believes presentation of EBITDA enhances
an understanding of financial condition, results of operations and cash flows
because EBITDA is used by the Company to satisfy its debt service obligations
and its capital expenditure and other operational needs, as well as to provide
funds for growth. In addition, EBITDA is used by senior lenders and the
investment community to determine the current borrowing capacity and to estimate
the long-term value of companies with recurring cash flows from operations. The
Company's computation of EBITDA may not be comparable to other similarly titled
measures of other companies. The following table provides a calculation of
EBITDA for the three months ended March 31, 2000 and 1999:

         Monthly Recurring Revenue ("MRR"). MRR is revenue that the Company is
entitled to receive under monitoring and service contracts in effect at the end
of the period. Because the Company has grown rapidly, often by acquiring
security alarm companies and portfolios of customer accounts which are included
in revenues only from the date of acquisition, the Company's revenues are not
proportional to the level of its investment of capital reported to the end of
the period upon which a return must be earned. Management believes MRR enhances
an investor's understanding of the Company's financial condition, results of
operations and cash flows because it provides a measure of the Company's revenue
that can be used to derive estimated annual revenues acquired in acquisitions
for a full year of operations. As a result, MRR can be compared to the level of
investment in the statement of financial condition at the end of the period. By
comparing MRR to cash, debt and equity balances at the end of a period, an
investor can assess the Company's investment track record. Further, management
believes an investor's consideration of MRR relative to the Company's customer
base helps identify trends in MRR per customer. MRR does not measure
profitability or performance, and does not include any allowance for future
losses of customers or allowance for doubtful accounts. The Company does not
have sufficient information as to the losses of acquired customers accounts to
predict with absolute certainty the amount of acquired MRR that will be realized
in future periods or the impact of the loss of acquired accounts on our overall
rate of customer loss. Our computation of MRR may not be comparable to other
similarly titled measures of other companies and MRR should not be viewed by
investors as an alternative to actual monthly revenue as determined in
accordance with generally accepted accounting principles. MRR at March 31, 2000
and 1999 was approximately $1,063,000 and $935,000, respectively.

         MRR Attrition. The Company experiences customer cancellations, i.e.,
attrition, of monitoring and related services as a result of subscriber
relocation, the cancellation of acquired accounts during the process of
integrating such accounts into the Company's operations, unfavorable economic
conditions and other reasons. This attrition is offset to a certain extent by
revenues from the sale of additional services to existing subscribers, the
reconnection of premises previously occupied by subscribers, the conversion of
accounts previously monitored by other alarm companies and guarantees provided
by the sellers of such accounts. The Company defines attrition numerically for a
particular period as a quotient, the numerator of which is equal to the
difference between gross MRR lost as the result of canceled subscriber accounts
and MRR lost that was replaced pursuant to guarantees from sellers of accounts
purchased by the Company, and the denominator of which is the expected month-end
MRR calculated at the end of such period. Net MRR attrition of the Company's
customers during the twelve months ended March 31, 2000 and 1999 was less than
10%, on an annualized basis.

Three Months Ended March 31, 2000 Compared to Three Months Ended March 31, 1999

         Revenue. Total revenues for the three months ended March 31, 2000
increased 13.5% to approximately $4.9 million from approximately $4.3 million
during the corresponding period in the prior year. Monitoring revenues for the
three months ended March 31, 2000 increased to approximately $3.1 million, or
12%, from approximately $2.8 million during the corresponding period of the
prior year. Installation and service revenues for the three months ended March
31, 2000 increased by 16% to approximately $1.8 million, compared to
approximately $1.5 million during the corresponding period of the prior year.
Total retail subscribers approximated 26,200 at March 31, 2000, compared to
22,700 at March 31, 1999, a net increase of 15%. The increase in monitoring
revenues and number of subscribers in the first quarter of 2000 from the first
quarter of 1999 is attributable to the Company's installation activity and to
the purchase of accounts in the latter part of 1999. The increase in
installation and service revenues in the first quarter of 2000 compared to the
prior year's quarter is a result of the Company's increased efforts in internal
installation activity.

         Operating Expenses. Total operating expenses, excluding depreciation
and amortization, for the three months ended March 31, 2000 increased 11% to
approximately $3.8 million, compared to approximately $3.4 million during the
corresponding period in the prior year. Monitoring expenses decreased 4% to
approximately $512,000, compared to approximately $533,000 during the
corresponding period in the prior year. As a percentage of monitoring revenues
during the three months ended March 31, 2000, monitoring expenses were 16%,
compared to 19% during the corresponding period in the prior year. The decrease
in monitoring costs was a result of cost efficiencies which

                                       11
<PAGE>

included the transfer of outside monitored accounts to the Company's monitoring
facilities. Installation and service costs during the three months ended March
31, 2000 increased by 21% to approximately $1.5 million, compared to
approximately $1.2 million during the corresponding period in the prior year.
Installation and service costs were 81% of related revenues during the three
months ended March 31, 2000, compared to 77% during the corresponding period in
the prior year, because the Company derived a larger percentage of sales from
lower revenue / higher cost sales to homeowners and builders in the quarter
ended March 31, 2000 compared to the quarter ended March 31, 1999.

         Gross Profit. Total gross profit, defined as total revenues less
monitoring and installation and service costs, increased by 13% to approximately
$2.9 million during the three months ended March 31, 2000, compared to
approximately $2.6 million during the corresponding period in the prior year.
Gross profit from monitoring revenues increased by 16% to approximately $2.6
million during the three months ended March 31, 2000, compared to approximately
$2.2 million during the corresponding period in the prior year. The increase in
gross profit from monitoring revenues is primarily attributable to the Company's
1999 acquisitions of monitored accounts for which the incremental costs to
monitor are lower than the Company's average cost in 1999, as well as more
efficient operations. Gross profit from installation and service activities
decreased to approximately $340,000 during the three months ended March 31,
2000, from approximately $350,000 during the corresponding period in the prior
year, partly due to the costs associated with the increased efforts in the
Company's internal installations operations.

         Selling, General and Administrative. Selling, general and
administrative costs ("SG&A") increased by 8% to approximately $1.8 million
during the three months ended March 31, 2000, compared to approximately $1.7
million during the corresponding period in the prior year. The increase in SG&A
costs in 2000 from 1999 is related primarily to additional personnel and
resources necessary to service the Company's growing customer base.

         Amortization of Customer Contracts. Amortization of customer contracts
decreased by less than 1%, remaining at approximately $1.2 million during the
three months ended March 31, 2000, compared to the corresponding period in the
prior year. This steady amortization expense can be mostly attributed to the
fact that account portfolio purchases have been in proportion to account
write-offs. Costs of acquired contracts are amortized over 10 years, unless a
contract is canceled and not replaced by the corresponding independent alarm
company, in which case the remaining unamortized balance is written off as a
charge to amortization expense.

         Depreciation and Amortization. Depreciation and amortization increased
by 21% to approximately $230,000 during the three months ended March 31, 2000,
compared to approximately $191,000 during the corresponding period in the prior
year. Such costs include depreciation of property and equipment (the gross
balance of which increased to approximately $5.8 million at March 31, 2000 from
approximately $5.4 million at March 31, 1999) and the amortization of certain
other intangible assets.

         Interest Expense and Other. Interest expense and other increased 16% to
approximately $296,000 during the three months ended March 31, 2000, compared to
approximately $256,000 during the corresponding period in the prior year. The
increase in interest expense resulted from increased borrowings under the
Renewed Credit Facility. Total borrowings under the Renewed Credit Facility
increased to approximately $10.4 million at March 31, 2000 from approximately
$6.4 million at March 31, 1999.

                                       12

         Net Loss. Net loss applicable to common stock for the three months
ended March 31, 2000 was approximately $(1.1) million, or $(0.12) per share,
compared to a net loss of approximately $(1.2) million, or $(0.13) per share,
during the corresponding period of the prior year.

Liquidity and Capital Resources

         As of March 31, 2000, the Company believes it will maintain the ability
to generate sufficient cash to fund future operations of the business.
Generally, cash flow will be generated from a combination of (1) the Company's
existing $20.0 million Renewed Credit Facility with Heller, subject to
compliance with the provisions of the debt covenants in the Renewed Credit
Facility, and (2) recurring revenue from its security monitoring customer base,
which generated $1.1 million of EBITDA in the three months ended March 31, 2000.
At March 31, 2000, there was $5.0 million of availability under the Renewed
Credit Facility. Cash flow from operating activities was $1.2 million for the
three months ended March 31, 2000.

         Capital Resources. The Renewed Credit Facility expires in May 2001.
Availability under the Renewed Credit Facility is subject to certain "Borrowing
Base" limitations (as defined in the Renewed Credit Facility). In connection to
the October 1998 investment by Protection One Investments, Inc. (see Note 10 to
the Company's Consolidated Financial Statements contained in the Company's
Annual Report on Form 10-KSB for the fiscal year ended December 31, 1999),
Heller consented to amendments to conform the agreement with the transactions.
The Renewed Credit Facility includes customary covenants, including, but not
limited to, restrictions related to the incurrence of other debt, the
encumbrance or sale of the Company's assets, and the payment of dividends or
making of other distributions to the Company's shareholders and other financial
performance covenants. The Company believes it was in compliance with all such
covenants as of March 31, 2000.

         The Renewed Credit Facility will be used primarily for acquisitions of
subscriber accounts. The Company's continued plan of growth through acquisitions
of subscriber accounts is contingent upon its ability to borrow under the
Renewed Credit Facility.

         Liquidity. Net cash provided by operating activities during the three
months ended March 31, 2000 was approximately $1.2 million. The Company incurred
a net loss of approximately $621,000 during such period; however, included in
such loss was non-cash depreciation and amortization expense, amortization of
customer contracts expense, amortization of capitalized installation costs and
amortization of deferred financing costs totaling approximately $1.8 million and
a bad debt provision of approximately $129,000. Other operating cash flows
included cash inflows of approximately $175,000 related to increases in accounts
receivable and unearned revenue and cash outflows of approximately $288,000
related to other assets and net decreases in liabilities.

         Net cash used in investing activities was approximately $919,000 during
the three months ended March 31, 2000 and was comprised of approximately
$541,000 used in the purchase and placement of customer accounts and the
purchases of fixed assets of approximately $378,000 which includes equipment
under lease at customer premises of approximately $253,000.

                                       13
<PAGE>

         Net cash used in financing activities was approximately $456,000 during
the three months ended March 31, 2000, consisting primarily of repayments to
Heller and other long-term debt of approximately $796,000, payment of cash
dividends on preferred stock of approximately $287,000, and costs related to the
issuance of equity securities of approximately $7,000. These payments were
offset by proceeds under borrowings from Heller of approximately $612,000. The
Company's cash balance was $378,607 as of March 31, 2000.

         Total shareholders' equity was $3,098,476 at March 31, 2000, decreasing
by a net amount of $1,076,513 during the three months ended March 31, 2000. The
net decrease resulted from the payment and accrual of dividends on the Company's
preferred stock of approximately $449,000 and the net loss of approximately
$621,000.

         Affiliation with Western Resources, Inc. As discussed in the Company's
1999 Form 10-KSB, in Part I, Item I "1999 Developments", Western Resources, Inc.
indirectly holds a significant investment in the Company.

         The Company does not currently have any significant commitments for
capital outlays.

Concentration of Credit Risk

         Financial instruments which potentially subject the Company to
concentrations of credit risk consist principally of trade receivables from a
large number of customers, including both residential and commercial customers.
The Company extends credit to its customers in the normal course of business,
performs periodic credit evaluations and maintains allowances for potential
credit losses.
