----------------------------------------------------------------------------

(1)  No bonuses were paid, no long-term compensation awards were made, and no
     other compensation was paid during 1999 to Mr. Paolino or any other
     executive officer of Mace. Robert M. Kramer, Mace's Executive Vice
     President and General Counsel, is paid at an annual rate of $125,000,
     Gregory M. Krzemien, Mace's Chief Financial Officer, is paid at an annual
     rate of $110,000, and Michael Fazio, Mace's Vice President - Operations, is
     paid at an annual rate of $100,000. Because these persons were not employed
     by Mace for the entire year, their annual compensation for the year ended
     December 31, 1999 was less than $100,000 each. Mr. Paolino was the only
     officer to receive compensation in excess of $100,000 in 1999. Mr. Paolino
     and Mr. Goodrich have never been granted options by Mace as compensation.
     Thus, tables disclosing information with respect to options granted in 1999
     to the named current and former executive officers of Mace and information
     with respect to the year-end value of options held by the named current and
     former executive officers of Mace have been excluded.

(2)  Mr. Paolino has served as President, Chief Executive Officer and Chairman
     of the Board since July 1, 1999.

(3)  Mr. Goodrich served as President and Chief Executive Officer until July 1,
     1999.

Director Compensation

     During 1998 and through July 1, 1999, directors who were not employees of
Mace received fees of $500 per Board or Committee meeting attended. Such
directors also were entitled to receive reasonable travel and out of pocket
expenses relating to their attendance at such meetings. Commencing on July 1,
1999, Mace ceased paying fees to directors, but will continue to pay non-
employee directors reasonable travel and out-of-pocket expenses relating to
their attendance at meetings.

     Mace granted options to purchase 20,000 shares of Mace common stock at
$11.00 per share to Constantine Papadakis in connection with his appointment to
the Board of Directors on May 24, 1999 and additional options to purchase 20,000
shares of Mace common stock at $8.50 per share on September 1, 1999. Mace
granted options to purchase 200,000 shares, 125,000 shares and 125,000 shares of
Mace common stock at $2.6875 per share, respectively, to Robert Kramer, Matthew
Paolino and Rodney Proto (a former director) on March 26, 1999 in connection
with the change of control transactions (see Item 12. Certain Relationships and
Related Transactions - Acquisition of Control of Mace.)

Option/SAR and Warrant Grants in Last Fiscal Year

     No options, warrants or stock appreciation rights (SAR's) were granted as
compensation to any executive officer included in the summary compensation table
during the fiscal year ended December 31, 1999 and no such securities were
exercised by any such officer. During that year, however, Robert M. Kramer,
Mace's Executive Vice

                                       4
<PAGE>

President and General Counsel, received grants of options to purchase 200,000
shares of Mace common stock, Gregory M. Kzemien, Mace's Chief Financial Officer
and Treasurer received grants of options to purchase 125,000 shares of Mace
common stock and Michael Fazio, Mace's Vice President - Operations, received
grants of options to purchase 125,000 shares of Mace common stock. Additionally,
on December 27, 1999 Robert Kramer was granted reload options to purchase 37,209
shares of Mace common stock at $5.50 per share and on December 29, 1999, Matthew
Paolino was granted reload options to purchase 37,209 shares of Mace common
stock at $5.50 per share. The shares issuable upon the exercise of these options
(to the extent that they are exercisable within 60 days of March 23, 2000) are
reflected in the table included under the caption "Security Ownership of Certain
Beneficial Owners and Management." In connection with the merger of American
Wash Services, Inc. on July 1, 1999 (see Item 12. Certain Relationships and
Related Transactions - AWS Transaction), Mr. Paolino received warrants to
purchase 1,500,000 shares of Mace common stock. Mace does not consider these
warrants to be compensation for Mr. Paolino's services under his employment
agreement or otherwise.

Aggregated Options/SAR and Warrant Exercises in Last Fiscal Year

     No options or warrants were received as compensation by executive officers
of Mace included in the Summary Compensation Table during the fiscal year ended
December 31, 1999. However, Louis D. Paolino, Jr. exercised 363,636 warrants

Item 12. Certain Relationships and Related Transactions.

Acquisition of Control of Mace

     On July 1, 1999, Louis D. Paolino, Jr., Mace's Chairman, President and
Chief Executive Officer, along with certain of his affiliates, acquired a
majority of the outstanding shares of Mace common stock and thus acquired
control of Mace.

                                       8
<PAGE>

     This acquisition of control involved a series of transactions approved by
the former Board of Directors of Mace and a majority of Mace's stockholders. The
consummation of this series of transactions changed the principal business of
Mace from the sale of personal security products to the operation and
consolidation of car wash facilities. On June 8, 1999 Mace distributed an
information statement to its stockholders describing, among other things, this
series of transactions.

     The first transaction involved the purchase from Mace of an aggregate of
3,735,000 unregistered shares of Mace common stock for $1.375 per share;
1,910,000 shares by Louis Paolino, Jr. and an aggregate of 1,825,000 shares by
certain members of his management team and certain other individuals designated
by Mr. Paolino. These purchases were made pursuant to a Stock Purchase Agreement
dated March 26, 1999 (as amended) between Mace and Mr. Paolino. Additional
related purchases were also made on July 1, 1999 pursuant to this Stock Purchase
Agreement:

     o    Louis Paolino, Jr. purchased 1,000,000 shares of Mace common stock
          directly from Mr. Goodrich for $1.375 per share and 100,000 shares of
          Mace common stock directly from each of two other stockholders of Mace
          for $1.375 per share;

     o    Robert M. Kramer purchased 50,000 shares of Mace common stock directly
          from Mr. Goodrich for $1.375 per share; and

     o    Ten individuals designated by Louis Paolino, Jr. purchased from Mace
          an aggregate of 1,850,000 shares of Mace common stock for $2.00 per
          share.

AWS Transaction

     The second transaction involved the merger of American Wash Services, Inc.,
a car wash facility company controlled by Louis Paolino, Jr. with and into a
wholly-owned subsidiary of Mace pursuant to a merger agreement entered into
March 26, 1999. The Merger was completed on July 1, 1999. Louis Paolino, Jr. and
Red Mountain Holdings, Ltd., American Wash's other shareholder, received in
exchange for all of the shares of American Wash, $4,687,500, in cash, and
628,362 unregistered shares of Mace common stock, of which Louis Paolino, Jr.
received 470,000 shares and Red Mountain received 158,362 shares. Louis Paolino,
Jr. and Robert Kramer received the following additional consideration in
connection with this Merger:

     o    Louis Paolino, Jr. received a warrant to purchase 1,500,000 shares of
          Mace common stock at a purchase price of $1.375 per share;

     o    Louis Paolino, Jr. received a warrant to purchase 250,000 shares of
          Mace common stock at a purchase price of $2.50 per share (which has
          subsequently been assigned to a third party); and

     o    Robert Kramer received a warrant to purchase 75,000 shares of Mace
          common stock at a purchase price of $1.375 per share.

     Mace's Board of Directors and management team were restructured in
connection with these transactions. Louis Paolino, Jr. was appointed as Mace's
Chairman, President and Chief Executive Officer. The entire Board of Directors,
other than Mr. Goodrich, resigned and were replaced and the Board

                                       9

<PAGE>

appointed Mr. Kramer as Mace's Secretary, Executive Vice President and General
Counsel and Mr. Krzemien as Mace's Chief Financial Officer and Treasurer.

Related Party Transactions

     In August 1999, Mace entered into a month-to-month lease with Bluepointe,
Inc., a corporation controlled by Louis Paolino, Jr., Mace's Chairman, President
and Chief Executive Officer, for Mace's executive offices in Mt. Laurel, New
Jersey. The lease provides for monthly rental payments of $10,000. Mace believes
that the terms of this lease are competitive when compared to similar facilities
in the Mt. Laurel, New Jersey area.

     Robert M. Kramer, Mace's General Counsel, Executive Vice President and
Secretary, is engaged in the practice of law through Robert M. Kramer &
Associates, P.C., a professional corporation owned by Mr. Kramer, which has
rendered legal services to Mace since April 1999. Mace paid such corporation
approximately $165,000 during fiscal year ended December 31, 1999, and 65,000
through March 31, 2000. Mace does not anticipate paying such corporation greater
than $200,000 for the remainder of this fiscal year.

     During fiscal year 1999, Mace paid approximately $391,000 for car wash
parts, equipment and related services to Sonny's Enterprises, Inc., a car wash
parts and equipment company owned by Paul G. Fazio, the brother of Michael
Fazio, Mace's Vice President of Operations. Mace contracted with Sonny's
Enterprises based on the quality of parts, equipment and services offered by
Sonny's Enterprises and the competitive prices that Sonny's Enterprises offered
for such parts, equipment and services.

     During fiscal year 1999, Mace paid $50,000 for charter airline services to
Air Eastern, a charter airline company owned by Louis D. Paolino, Jr., Mace's
Chairman of the Board, Chief Executive Officer and President. Mace believes that
the rates charged are competitive when compared with similar services provided
by independent airline charter companies.
