Compensation Committee Report on Executive Compensation

The Compensation Committee of the Company's Board of Directors consisted of
directors Louis D. Paolino, Jr., Richard B. Muir, and Constantine N. Papadakis,
Ph.D. Mr. Muir resigned due to other business commitments from the Board of
Directors as well as his position on the Compensation Committee effective
October 15, 2003.

The following report of the Compensation Committee is required by the rules of
the Securities and Exchange Commission to be included in the Company's Proxy
Statement or the Company's Annual Report on Form 10-K and addresses the
Company's executive compensation policies for the fiscal year ended December 31,
2003. This report shall not be deemed incorporated by reference into any filing
under the Securities Act of 1933, as amended (the "Securities Act"), or the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), by virtue of
any general statement in such filing incorporating this Form 10-K by reference,
except to the extent that the Company specifically incorporates the information
contained in this section by reference, and shall not otherwise be deemed filed
under either the Securities Act or the Exchange Act.

General. The Company's compensation policies for executives are intended to
further the interests of the Company and its stockholders by encouraging growth
of its business through securing, retaining, and motivating management employees
of high caliber who possess the skills necessary to the development and growth
of the Company.

The Company's current compensation package consists of two components: base
salaries and stock options. Together these elements comprise total compensation
value. The total compensation paid to the Company's executive officers is
influenced significantly by the need (i) to attract management employees with a
high level of expertise, and (ii) to motivate and retain key executives for the
long-term success of the Company and its stockholders.

The fiscal year ended December 31, 2003, was a challenging year for the Company.
In 2003, Mace focused its management efforts on maximizing operating profits in
an economy which had suffered a downturn. Managements efforts were also focused
on developing the Company's security electronics surveillance business.
Additionally, the financing and re-financing of the Company's long-term debt
demanded significant time and attention. The Compensation Committee considered
these numerous factors and the Company's financial results in formulating its
executive compensation policies and practices for fiscal 2003. The Committee
also considered the Amper, Politziner and Mattia, P.C. study of compensation
levels dated May 2003 for each executive position when determining compensation.
The May 2003 compensation study by Amper, Politziner and Mattia, P.C. concluded
that the total compensation packages for the top four executive officers fell
below the peer group's 25th percentile. After considering all factors and
through negotiation of a new employment agreement by Mr. Paolino, an annual base
salary increase was given to Louis D. Paolino, Jr. in the amount of $50,000
bringing Mr. Paolino's base salary to $400,000.

<PAGE>

Other than the annual salary increase given in 2003, Mr. Paolino, had not been
given a salary increase from the date he was hired by the Company in 1999.
Additionally on July 14, 2003, options to purchase 150,000 shares of the
Company's common stock were granted each of Louis D. Paolino, Jr., Robert M.
Kramer and Gregory Krzemien and on November 14, 2003 options to purchase 100,000
shares of the Company's common stock were granted to Ronald R. Pirollo. The
options have an exercise price of the market price at the date of grant.

Base Compensation. The Committee established annual base salary levels for its
executives based on competitive data, level of experience, position,
responsibility, and individual and Company performance. The Committee has used
comparative data provided by Amper, Politziner and Mattia, P.C. The Company has
maintained total compensation levels for executives below the median in the
range of survey data, which included companies providing consumer services on a
national basis. The primary terms of the employment agreements of Robert M.
Kramer, Gregory M. Krzemien, and Ronald R. Pirollo expired on March 26, 2003.
Messrs. Kramer and Krzemien are working on a month-to-month at will-basis. Mr.
Pirollo or the Company may terminate Mr. Pirollo's employment at any time.

Stock Options. The Company grants stock options to its executive management
under its employee stock option plans. Option grants are intended to offer
significant returns if the Company is successful and, therefore, create
significant incentives to devote the effort called for in order to implement the
Company's strategic plan. The Compensation Committee believes that executives'
interests are directly tied to enhanced stockholder value. Thus, stock options
are used to provide the executive management team with a strong incentive to
perform in a manner that should result in the long-term success of the Company.

Performance Bonuses. The Company maintains the option to supplement base
compensation with awards of performance bonuses in the form of cash and/or stock
options to reward efforts undertaken by its key executive officers which are
extraordinary in nature.

Chief Executive Officer Compensation. Mr. Paolino, in his capacity as Chairman
of the Board, Chief Executive Officer, and President, participates in the same
compensation programs as the other executive officers. The Committee increased
Mr. Paolino's compensation on August 12, 2003 to $400,000. The Committee
believes that Mr. Paolino's compensation is competitive with the amount paid by
companies in similar industries and competitive situations, as supported by a
competitive compensation analysis conducted by Amper, Politziner and Mattia,
P.C. and the Compensation Committee's review of Mr. Paolino's salary in the
context of (i) the Company's performance and growth, and (ii) compensation
packages of chief executive officers at comparable companies.
