                 Mace Reports Profit of $.03 Per Share
for the 2nd Qtr of 2005, and a 262% Increase in Security Segment Sales
                       for the 2nd Qtr of 2005


    MOUNT LAUREL, N.J.--(BUSINESS WIRE)--Aug. 9, 2005--Mace Security
International, Inc. ("Mace" or "the Company") (Nasdaq:MACE), a
manufacturer of electronic surveillance, security and personal defense
products, and an owner and operator of car and truck wash facilities,
today announced a profit of $.03 per share for the three months ended
June 30, 2005. Mace also announced a 262% sales increase in the
Security Segment, rising from approximately $2.0 million in the second
quarter of 2004 to approximately $7.2 million in the second quarter of
2005.
    The Company is pleased with the continued sales growth and the
profitability of its Security Segment. For the quarter ended June 30,
2005, the Security Segment represented approximately 39% of the
Company's sales, which is a substantial increase from approximately
16% for the second quarter of last year. Mace continues to explore the
sale of its car and truck washes with the goal of using the proceeds
to fund further expansion of its Security Segment.

    Financial Results - First Half of 2005 compared to First Half of
2004

    Total revenues for the six months ended June 30, 2005 were $35.6
million compared to $25.3 million for the same period in 2004. The
increase in revenues over last year was primarily due to revenues from
the Security Segment, which increased from $3.9 million in the first
half of 2004 to approximately $13.6 million in first half of 2005, an
increase of approximately $9.7 million, or 251%.
    Revenues from the Car and Truck Wash Segment increased by
approximately $610,000, or 2.9%, in the first half of 2005 compared to
the same period in 2004, primarily the result of an improvement in
weather resulting in a 4.2% increase in car wash volume, partially
offset by the divesture of two car wash facilities during the first
half of 2004. The increase in revenues from the Security Segment was
principally due to internal growth in sales to security system
installers, and $7.2 million of sales generated by two businesses we
acquired in July of 2004.
    Gross profit as a percentage of revenues remained constant at
approximately 28% for both the first half of 2005 and 2004. The gross
profit percentage for 2005 was comprised of 29% for the Security
Segment and 27% for the Car and Truck Wash Segment, while the 2004
percentage was comprised of 36% for the Security Segment and 27% for
the Car and Truck Wash Segment. The decrease in gross profit
percentage in the Security Segment was primarily the result of growth
in sales of advanced imaging components and video equipment sold by
Industrial Vision Source ("IVS"), increased sales of monitors which
typically have gross profit margins lower than other security
products, and an increase in sales to distributors.
    Selling, general and administrative ("SG&A") expenses for the
first six months of 2005 increased by $2.4 million over the first six
months of 2004, primarily due to the expansion of the Security
Segment. The increases were in the areas of advertising costs and
marketing, selling and administrative personnel costs as staff was
added to handle planned growth of the Security Segment. Additionally,
corporate overhead costs increased approximately $260,000 in the first
half of 2005 over the same period in 2004, primarily in the areas of
insurance, audit and consulting, and compensation costs.
    Operating income for the first half of 2005 was approximately $1.4
million as compared to $1.1 million in the first half of 2004. The
increase was principally the result of the increased revenues from
both the Security and Car and Truck Wash Segments, partially offset by
the aforementioned increase in SG&A expenses. Net income was $450,000,
or $0.03 per share, and $203,000, or $0.02 per share, for the six
months ended June 30, 2005 and 2004, respectively.

    Financial Results - Second Quarter of 2005 compared to Second
Quarter of 2004

    Total revenues for the three months ended June 30, 2005 were $18.8
million compared to $12.6 million for the same period in 2004. The
increase in revenues over last year was primarily due to revenues from
the Security Segment, which rose from approximately $2.0 million in
the second quarter of 2004 to $7.2 million in second quarter of 2005,
an increase of approximately $5.2 million, or 262%.
    Revenues from the Car and Truck Wash Segment increased by
$924,000, or 8.7%, in the second quarter of 2005 compared to the same
period in 2004, primarily the result of an improvement in weather
resulting in a 12.7% increase in car wash volume, partially offset by
the divesture of two car wash facilities during the first half of
2004. The increase in revenues from the Security Segment was
principally due to internal growth in sales to security system
installers, and $3.7 million of sales generated by two businesses we
acquired in July of 2004.
    Gross profit as a percentage of revenues increased to 29% for the
second quarter of 2005 compared to 27% for the same period in 2004.
The gross profit percentage for 2005 was 30% for the Security Segment
and 28% for the Car and Truck Wash Segment, while the 2004 percentage
was 34% for the Security Segment and 26% for the Car and Truck Wash
Segment. The decrease in gross profit percentage in the Security
Segment was primarily the result of growth in sales of advanced
imaging components and video equipment sold by IVS, increased sales of
monitors which typically have gross profit margins lower than other
security products, and an increase in sales to distributors. The
increase in the Car and Truck Wash Segment gross profit percentage was
primarily due to an increase in wash volume combined with reductions
in certain direct operating expenses including an improvement in labor
costs as a percentage of revenues.
    SG&A expenses for the second quarter of 2005 increased by
approximately $1.2 million over the second quarter of 2004, primarily
due to the expansion of the Security Segment. The increases were in
the areas of advertising costs and marketing, selling and
administrative personnel costs as staff was added to handle planned
growth of the Security Segment. Additionally, corporate overhead costs
increased approximately $139,000 in the second quarter of 2005 over
the same period in 2004, primarily in the areas of insurance, audit
and consulting, and compensation costs.
    Operating income for the second quarter of 2005 was $1.0 million
as compared to $429,000 in the second quarter of 2004, an increase of
$579,000, or 135%. The increase was principally the result of the
increased revenues from both the Security and Car and Truck Wash
Segments, partially offset by the aforementioned increase in SG&A
expenses. Net income was $439,000, or $0.03 per share, in the second
quarter of 2005 compared to a loss of $14,000 in the same period of
2004.
    The Company's net book value was $66.9 million, or $4.38 per
share, at June 30, 2005. In addition, Mace had $101 million in total
assets, including $14.3 million of cash and short-term investments at
June 30, 2005.
