This statement relates to shares of Common Stock (the "Stock") of Mace Security International, Inc. (the "Issuer"). The principal executive office of the Issuer is located at 1000 Crawford Place, Suite 400, Mt. Laurel, NJ 08054.

The source and amount of funds used in purchasing the Stock were as follows:

As disclosed in the Prior Letters and an August 31st letter sent by Lawndale to Mace's Board of Directors, summarized in greater detail below, (a copy of which is attached as Exhibit B hereto, and incorporated by reference in this filing) Lawndale has made a number of specific suggestions to Mace's management and directors in an effort to improve the Company's board and governance structures, including changes to the Board's composition and processes. As part of these efforts Lawndale has offered a variety of proposals designed to allay the Company' alleged concerns that Lawndale is seeking control of the Company, all of which have been rejected by the Company. At the same time, Lawndale believes that Mace Chairman & CEO, Louis Paolino, Jr. has sought to mischaracterize Lawndale's nominees and objectives to others, including wrongly claiming to the Nominating Committee that Lawndale is seeking control of the Company or that Lawndale's nominees are controlled by Lawndale. In fact, as disclosed in the Prior Letters, the August 31st letter, and in Lawndale's communications with the Company, Lawndale is seeking solely to improve the quality and role of the Company's independent directors, and has nominated individuals who are independent of Lawndale as well as highly qualified. To date, Louis Paolino, Jr. has claimed the Company's existing directors are unwilling to consider either expanding the Board to add additional independent directors or resigning from the Board to allow new independent directors to join the Board. Lawndale has requested the Nominating Committee independently review the independence and qualifications of its nominees and conduct future dialogue with Lawndale directly.

Lawndale's sole focus remains to enhance the Company's governance structure to enhance shareholder value, and if this goal can be achieved on a cooperative basis at reduced expense and distraction, Lawndale is anxious to do so and shall continue to pursue this objective. However, Lawndale is increasingly concerned that the only way necessary governance improvements can occur is through the means of a proxy contest.

In a letter dated June 15, 2007 (the "Seven Person Board Proposal") which was attached as Exhibit B to Schedule 13D, Amendment No. 3, Lawndale requested the addition of three new independent directors to comprise a minority of Mace's Board via a two-director expansion of the Board (from five to seven members) along with the departure from the Board of non-independent director, Matthew Paolino, Mace Vice President and brother of Chairman & CEO, Louis Paolino, Jr. These changes would result in a modified board composition consisting of the three legacy "independent" directors, the three new independent directors and one management member, Louis Paolino, Jr.

On August 29, 2007, Lawndale sent Mace a letter (a copy of which is attached as Exhibit C hereto, and incorporated by reference in this filing) in which Lawndale formally submitted the name and background information of an additional highly qualified individual, Philip Livingston, along with the required information for the three director nominees, whose names and biographical information were provided in Lawndale's June 15th letter to Mace's Nominating Committee for formal consideration. Biographical information on Mr. Livingston can be found at http://www.phillivingston.com/biography.htm . Lawndale believes that each of these independent nominees would add significant expertise and value to Mace's Board.

On August 31, 2007, following discussions with Louis Paolino, Jr., Lawndale sent Mace's Board of Directors a letter. In this letter, in addition to reiterating its Seven Person Board Proposal, Lawndale, in the spirit of compromise, offered an alternative proposal (the "Five Person Board Proposal") intended to also improve the independent composition and structure of Mace's Board. Lawndale's Five Person Board Proposal called for changes in the composition of Mace's Board whereby Matthew Paolino, as well as two of the incumbent "independent" directors, would be replaced by two of the highly qualified independent nominees submitted by Lawndale and a fourth independent director unanimously selected by the three independent directors (Mace's incumbent independent director and the two new independent directors). Under this scenario, four of the five Mace board members would be independent, and three of the five would be new to Mace's Board.

Lawndale believes, given the operating history and oversight experience of the nominees it submitted, either proposal it has made to Mace's Board would result in an improved Board composition and structure.

Lawndale continues to be in discussions with Mace's management and Board in an effort to resolve this matter in a constructive way and to avoid a proxy contest.

Lawndale has been and may continue to be in contact with Mace management, members of Mace's Board of Directors, other significant shareholders and others regarding these and additional steps that Mace could employ to maximize shareholder value.

Lawndale believes the public market value of Mace, currently trading below it's tangible book value, is undervalued by not adequately reflecting the value of Mace's assets and business divisions. Lawndale acquired the Stock solely for investment purposes, and Lawndale may from time to time buy or sell the Stock at its discretion.

Lawndale incorporates by reference its activities and discussions disclosed in its prior Schedules 13D to the extent not inconsistent with the discussion herein.

Mr. Robert M. Kramer

Corporate Secretary

Mace Security International, Inc.

1000 Crawford Place, Suite 400

To the Board Members of Mace:

As you know, Lawndale Capital Management, LLC, through the funds it manages, remains Mace's largest shareholder, now owning more than 9.5% of Mace's stock. With this week's nomination of Phil Livingston, we have formally submitted nominations for four of the five seats on Mace's board of directors. As we have made clear in our prior correspondence, we have done this because we believe the Company's poor corporate governance has resulted in Mace's dismal performance, and because Mace's current independent directors are not providing the type of oversight and leadership necessary to fix this Company.

At the same time, and as we have also made clear, we remain interested in working constructively with Mace's management and board to see if mutually agreed upon changes to the Board can be made that could potentially improve Mace's governance and performance without the need for a contested election. In this regard, and as you will recall, more than two months ago, on June 15, 2007 we submitted for the consideration by Mace's Nominating Committee the resumes of three qualified and truly independent individuals to be appointed to Mace's board. These individuals would provide the type of leadership, experience and oversight that Mace clearly needs.

In yet one more effort to reach an accommodation with you, and avoid the costs and distraction, which inevitably arise in any contested election, we would again like to propose a compromise to help immediately improve Mace's board and governance. Specifically, and based upon our conversation with Lou Paolino, we hereby offer two proposals in an effort to resolve this matter short of a contested election.

The proposals are as follows:

Please note that the purpose of this letter is to make one more effort to resolve this matter prior to the commencement of a distracting and expensive proxy contest. As Mace's largest shareholder it gives us no pleasure to run a proxy contest during which the Company will inevitably waste valuable shareholder resources. However, the board's poor governance and oversight--which has contributed to the Company's poor performance--cannot be ignored any longer. If we cannot reach agreement we will continue our effort to change the entire board, and we fully believe we will be successful.

Lou has said that the ultimate decision on these proposals is up to Mace's independent directors. If that is the case then we request that a Board representative contact us as soon as possible to discuss this matter expeditiously. We are making this offer at this time because we believe it is in the best interests of the Company and its shareholders to resolve these issues as soon as possible, and in a constructive manner. We hope you agree, and will quickly work with us to improve Mace's governance and performance.

We await your prompt reply.

Sincerely,

Andrew Shapiro

President
