Mace Security International Reports Increases in Revenues for the
          First Half and Second Quarter of Fiscal Year 2003

    MOUNT LAUREL, N.J.--(BUSINESS WIRE)--Aug. 12, 2003--Mace Security
International, Inc. ("Mace") (Nasdaq: MACE), a manufacturer and
marketer of security products and a leading provider of car care
services, today announced financial results and increases in revenues
of 5.5% and 3.8%, respectively, for the first half of 2003 and the
quarter ended June 30, 2003.

    Financial Results

    Revenues for the six months ended June 30, 2003 were $24.9 million
as compared to $23.6 million for the first half of 2002, an increase
of $1.3 million, or 5.5%. The increase in revenues over last year's
first six months was principally due to the operations of the Security
Products Segment. Revenues for the six months ended June 30, 2003 for
the Security Products Segment were $2.3 million compared to
approximately $400,000 in the same period of 2002 due to a
recommencing of operations in this segment in May of 2002. This
increase in revenues from the Security Products Segment was partially
offset by a decrease in car wash and detailing revenues in the first
six months of 2003 largely as a result of continued weather-related
volume declines in our Texas, Florida and Northeast regions.
Additionally, management was able to increase average wash and detail
revenue per car from $13.83 in the first half of 2002 to $14.39 in
2003, a 4.0% increase.
    Gross profit as a percentage of revenues was 28.3% in the first
six months of 2003 as compared to 31.4% in the first six months of
2002. The 2003 gross profit percentage is comprised of 26.9% for the
car and truck wash segment (versus 31.0% in the first six months of
2002) and 42.4% for the Security Products Segment in 2003 as compared
to 43.3% in 2002. The primary reasons for the decrease in gross profit
percentage within the car and truck wash segment were increased
insurance premiums and related claim costs, and the Company's decrease
in car wash volume. These negative influences on gross profit margin
were partially offset by certain temporary and permanent cost saving
measures instituted in March of 2003 including reductions in payroll
and related benefits costs and certain other operating costs.
    Operating income for the first six months of 2003 was $1.6 million
(exclusive of a non-cash asset impairment charge of $351,000 in the
second quarter) as compared to $2.6 million for the same period of
2002. The decrease in operating income is the result of the decrease
in car wash segment gross profit combined with an increase of $617,000
in selling, general and administrative ("SG&A") expenses including an
increase in SG&A expenses of $750,000 due directly to resuming
operations of the Security Products Segment. EBITDA for the six months
ended June 30, 2003 was $2.8 million, or 11.1% of revenues (exclusive
of a non-cash asset impairment charge), as compared to EBITDA in the
first six months of 2002 of $3.7 million, or 15.8% of revenues. Net
income for the first six months of 2003 was $254,000 or $.02 per share
($479,000 or $.04 per share exclusive of the asset impairment charge,
net of applicable income taxes) as compared to a net loss of $4.7
million or $.37 per share in the first six months of 2002. The net
loss in 2002 included a charge of $5.7 million, net of applicable
income taxes, as a cumulative effect of a change in accounting
principle relating to implementation of Financial Accounting Standard
142, Goodwill and Other Intangible Assets.
    In the second quarter ended June 30, 2003, we fully wrote down, by
$351,000, assets determined to be impaired. The asset write-down
related to a full service car wash site in Arizona which we partially
wrote down at December 31, 2002. The additional write-down was the
result of the impending loss of a significant customer to this site
resulting in the future expected cash flows not being sufficient to
recover the site's carrying value.
    Revenues for the three months ended June 30, 2003 were $12.3
million as compared to $11.9 million for the same period of 2002, an
increase of approximately $450,000. The increase in revenues over last
year's second quarter was due to the Security Products Segment
revenue, which increased by approximately $750,000 due to a
recommencing of operations in this segment in May of 2002. This
increase in revenues from the Security Products Segment was partially
offset by a decrease in car wash and detailing revenues in the second
quarter of 2003 as a result of continued weather-related volume
declines in our Texas, Florida and Northeast regions. The
volume-related decline in car wash revenues was partially offset by an
increase in average wash and detail revenue per car from $13.96 in the
second quarter of 2002 to $14.98 in 2003, a 7.3% increase.
    Gross profit as a percentage of revenues was 27.4% in the second
quarter of 2003 as compared to 30.2% in the same period of 2002. The
2003 gross profit percentage is comprised of 25.8% for the car and
truck wash segment (versus 29.6% in the second quarter of 2002) and
43.4% for the Security Products Segment in 2003 as compared to 43.3%
in 2002. The primary reasons for the decrease in gross profit
percentage within the car and truck wash segment were increased
insurance premiums and related claim costs, and the Company's decrease
in car wash volume. These negative influences on gross profit margin
were partially offset by certain permanent cost saving measures
instituted in March of 2003.
    Operating income for the quarter ended June 30, 2003 was $640,000
(exclusive of a non-cash asset impairment charge of $351,000 in the
second quarter) as compared to $1.0 million for the same period of
2002. The decrease is the result of the decrease in car wash segment
gross profit combined with an increase of $200,000 in SG&A expenses
including $280,000 due directly to resuming operations of the Security
Products Segment. EBITDA for the quarter ended June 30, 2003 was $1.2
million, or 9.9% of revenues (exclusive of the asset impairment
charge), as compared to 2002 EBITDA of $1.6 million, or 13.7% of
revenues. The second quarter of 2003 resulted in a net loss of $88,000
or $.01 per share (net income of $137,000 or $.01 per share exclusive
of the asset impairment charge, net of applicable income taxes) as
compared to net income of $357,000 or $.03 per share in the second
quarter of 2002.
    The Company's net book value was $57.9 million or $4.67 per share
at June 30, 2003. In addition, Mace has $94.9 million in total assets
including approximately $62 million of real estate in high traffic
retail areas and $5.3 million in cash and cash equivalents at June 30,
2003, and an experienced senior management team with a high equity
stake in the Company. In light of Mace's book value per share and
solid business fundamentals, the Company believes that its shares are
undervalued.
    In December 2002 the Company effected a one-for-two reverse stock
split. Accordingly, all shares and per share figures reflect the
effect of the reverse stock split.

    The Company included within this press release EBITDA, which is a
non-GAAP financial measure. EBITDA is calculated as net income adding
back interest expense, income taxes, depreciation and amortization
expense and certain non-cash charges. We believe that EBITDA, as
presented, represents a useful measure of assessing the performance of
our operating activities and resources available for strategic
opportunities, as it reflects our earnings trends, without the impact
of certain non-cash and unusual charges or income. EBITDA is also used
by our creditors in assessing debt covenant compliance. We understand
that, although securities analysts frequently use EBITDA in the
evaluation of companies, it is not necessarily comparable to other
similarly titled captions used by other companies due to potential
inconsistencies in the method of calculation. EBITDA is not intended
as an alternative to cash flow provided by operating activities as a
measure of liquidity, as an alternative to net income as an indicator
of our operating performance, nor as an alternative to any other
measure of performance in conformity with generally accepted
accounting principles.

    Certain statements and information included in this press release
constitute "forward-looking statements'' within the meaning of the
Federal Private Securities Litigation Reform Act of 1995. When used in

respond to the growth, its ability to achieve operating synergies, its
ability to compete, regulatory matters, the effects of competition,
its ability to maintain the control of the Company's cash business,
and the ability of the Company to obtain additional financing. Such
factors could materially adversely affect the Company's financial
performance and could cause the Company's actual results for future
periods to differ materially from any opinions or statements expressed
within this press release. Additional discussion of factors that could
cause actual results to differ materially from management's

    (1) The statement of operations for the six months ended June 30,
    2002 has been restated to reflect (i) the recording of the
    cumulative effect of a change in accounting principle, in
    accordance with SFAS No. 142, and (ii) the effect on shares and
    per share data of the (1) one-for-two reverse stock split in
    December of 2002.

    (2) EBITDA is calculated as income before cumulative effect of a
    change in accounting principle adding back interest expense,
    income taxes, depreciation and amortization expense and certain
    non-cash charges. We believe that EBITDA, as presented, represents
    a useful measure of assessing the performance of our operating
    activities and resources available for strategic opportunities, as
    it reflects our earnings trends, without the impact of certain
    non-cash and unusual charges or income. EBITDA is also used by our
    creditors in assessing debt covenant compliance. We understand
    that, although securities analysts frequently use EBITDA in the
    evaluation of companies, it is not necessarily comparable to other
    similarly titled captions used by other companies due to potential
    inconsistencies in the method of calculation. EBITDA is not
    intended as an alternative to cash flow provided by operating
    activities as a measure of liquidity, as an alternative to net
    income as an indicator of our operating performance, nor as an
    alternative to any other measure of performance in conformity with
    generally accepted accounting principles. The following is a
    reconciliation of EBITDA to net income.
