Item 7     Financial Statements and Exhibits.

           (c)   The following Exhibits are hereby filed as part of this Current
                 Report on Form 8-K.

                 99.1  Press Release issued by Mace Security International, Inc.
                       dated August 12, 2004.


Item 12    Results of Operations and Financial Condition

           On August 12, 2004, Mace Security International, Inc. issued a press
           release announcing its financial results for the first six months and
           second quarter ended June 30, 2004. A copy of the press release is
           attached as Exhibit 99.1 and is incorporated herein by reference in
           its entirety.

           The press release contains a non-GAAP financial measure, EBITDA.
           EBITDA is calculated as income before cumulative effect of a change
           in accounting principle adding back interest expense, income taxes,
           depreciation and amortization expense. 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 charges. EBITDA is also used by our creditors in
           assessing debt covenant compliance. We understand that, although
           security analysts frequently use EBITDA in the evaluation of
           companies, it is not necessarily comparable to other similarly titled
           captions of 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.

Pursuant to the requirements of the Securities and Exchange Act of 1934, the

undersigned hereunto duly authorized.
