     On July 1, 2004, Mace Security International, Inc., a Delaware corporation
(the "Company" or "Registrant"), through its wholly owned subsidiary, Mace
Security Products, Inc., acquired substantially all of the operating assets of
two operating divisions, namely, Industrial Vision Source(R)("IVS") and
SecurityandMore(R)("S&M"), of MDI Operating, L.P., a wholly owned subsidiary of
American Building Control, Inc. The asset acquisition was pursuant to the terms
of an Agreement for Purchase and Sale of Assets dated June 21, 2004 ( the
"Agreement"), by and among the Registrant, MDI Operating, L.P., and American
Building Control, Inc. (collectively the "Sellers").

     The assets (the "Purchased Assets") include substantially all of the assets
of the Sellers used in the business of operating S&M and IVS, which are a
supplier of "do-it-yourself" video surveillance and security equipment and a
distributor of technologically advanced imaging components and video equipment,
respectively.

     The Sellers are neither affiliated with the Registrant nor with any of the
Registrant's subsidiaries, affiliates, directors, officers, or any associates of
any director or officer. The description of the acquisition transaction set
forth herein is qualified in its entirety by reference to the Agreement which is
incorporated by reference as Exhibit 2.1.

     Pursuant to the Agreement, Registrant purchased the assets for cash
consideration of $5,621,000, subject to final adjustment as set forth in the
Agreement. The source of funds used by the Registrant to acquire the Purchased
Assets was the operating capital of the Registrant. The acquisition will be
accounted for as a business combination in accordance with Statement of
Financial Accounting Standards No. 141, "Business Combinations."

             REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders
American Building Control, Inc.

     We have audited the accompanying balance sheet of the SecurityandMore and
Industrial Vision Source divisions (collectively the "DSG Businesses") of
American Building Control, Inc., as of December 31, 2003, and the related
statements of operations and cash flows for the year then ended. These financial
statements are the responsibility of the DSG Businesses' management. Our
responsibility is to express an opinion on these financial statements based on
our audit.

     We conducted our audit in accordance with the standards of the Public
Company Accounting Oversight Board (United States). Those standards require that
we plan and perform the audit to obtain reasonable assurance about whether the
financial statements are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audit provides a reasonable basis for our opinion.

     In our opinion, the financial statements referred to above present fairly,
in all material respects, the assets acquired and liabilities assumed of the DSG
Businesses as of December 31, 2003, and the results of their operations and cash
flows for the year then ended in conformity with accounting principles generally
accepted in the United States of America.

consummated the acquisition of the consumer/do-it-yourself business
("SecurityandMore"(R)) and the industrial vision business (Industrial Vision
Source, or "IVSTM"), (collectively the "DSG Businesses"), of American Building
Control, Inc., (the "Company"), pursuant to a purchase agreement (the "Purchase
Agreement"), dated June 21, 2004, between the Company and Mace (the
"Acquisition").

     The consideration paid in the Acquisition (which was determined as a result
of arms'-length negotiations) consisted of cash in the amount of $5,620,834.

     The Company has two operating segments: the Professional Security Group
("PSG"), whose primary focus is access control and alarm management products and
the Diversified Sales Group ("DSG"), which includes products sold to the
consumer/do-it-yourself channel and its industrial video businesses. The DSG
segment is primarily comprised of the DSG Businesses.

     The accompanying carve-out balance sheets, statements of operations, and
statements of cash flows have been prepared for the purpose of complying with
the rules and regulations of the Securities and Exchange Commission. These
financial statements have been prepared on a historical cost basis from the
books and records maintained by the Company, on the basis of established
accounting methods, practices and procedures and policies (see Note 2) and the
accounting judgments and estimation methodologies used by the Company, of which
the DSG Businesses represented specific business units. The DSG Businesses never
operated as separate entities, but rather were integrated parts of the Company's
consolidated operations.

     The carve-out financial statements include the direct revenue and direct
operating expenses that relate to the DSG Businesses. Direct operating expenses
include salaries and wages, fringe benefits, materials, depreciation, and other
expenses solely attributable to the DSG Businesses. In addition, the carve-out
financial statements also include allocations of corporate expenses incurred by
the Company that are associated with the revenue-producing activities of the DSG
Businesses and are therefore indirectly attributable to the DSG Businesses. Such
allocated costs include sales and marketing costs, corporate overhead such as
finance, accounting, human resources, information systems costs, and occupancy
and procurement costs, which have been allocated using allocation factors such
as square footage, headcount and workload.

Note 2: Summary of Significant Accounting Policies

     Trade Accounts Receivable

     The DSG Businesses estimate the collectibility of trade accounts
receivable. In order to assess the collectibility of these receivables, the DSG
Businesses monitor the current creditworthiness of each customer and analyze the
aging of related past due balances. These evaluations may indicate a situation
in which a customer cannot meet its financial obligations due to deterioration
of its financial viability, credit ratings or bankruptcy. The allowance
requirements are based on current facts and are reevaluated and adjusted as
additional information is received. Trade accounts receivable are reserved when
it is determined the receivable may not be collected.




     Use of Estimates

     In preparing financial statements in conformity with accounting principles
generally accepted in the United States of America, the DSG Businesses'
management is required to make estimates and assumptions that affect the
reported amounts of assets and liabilities and disclosure of contingent assets
and liabilities on the date of the financial statements and revenues and
expenses during the reporting period. Actual results could differ from those
estimates.

     Inventories

     Inventories are comprised primarily of goods held for resale and are stated
at the lower of cost (first-in, first-out) or market through the use of an
inventory valuation allowance. In order to assess the ultimate realization of
inventories, the DSG Businesses are required to make judgments as to future
demand requirements compared to current or committed inventory levels. Allowance
requirements generally increase as the projected demand requirement decreases
due to market conditions and technological or product life cycle changes.

     Goodwill

     The DSG Businesses adopted Statement of Financial Accounting Standards
("SFAS") No. 142, Goodwill and Other Intangible Assets, on January 1, 2002. In
performing the impairment analysis required by SFAS No. 142, the DSG Businesses
complete a two step process to determine the amount of any impairment as of
December 31st of each year. The first step involves comparison of the fair value
of the reporting unit to its carrying value to determine if an impairment may
exist. The second step involves comparison of the fair value of the goodwill to
the carrying value of the goodwill. Any excess of the carrying value over the
fair value is recorded as an impairment charge. In calculating an impairment
charge, the fair value of a reporting unit is estimated using discounted cash
flow methodology or other valuation methods.

     In connection with the DSG Businesses' annual impairment analysis as of
December 31, 2003, no impairment was necessary based on the estimated proceeds
to be received from the anticipated sale of the DSG Businesses.

     Income Taxes

     Operating results of the DSG Businesses are included in the consolidated
income tax returns of the Company. The Company has significant net operating
loss carryforwards and has provided a full valuation allowance against its net
deferred tax assets. Accordingly, the consolidated financial statements of the
Company contain no provision for income taxes. The income tax expense presented
in these financial statements has been determined on a standalone basis for the
DSG Businesses assuming an effective tax rate equivalent to that of the Company
prior to the valuation allowance for deferred taxes and is not necessarily
reflective of actual tax expense that may have been attributable to the DSG
Businesses.

     Revenue Recognition

     Revenue is recognized when a firm sales agreement is in place, the price is
fixed and determinable, delivery has occurred and collectibility is probable.

     Warranty Reserves

     Reserves are provided for estimated warranty costs when revenue is
recognized. The costs of warranty obligations are estimated based on the
Company's warranty policy or applicable contractual warranty, historical
experience of known product failure rates and use of materials and service
delivery charges incurred in correcting product failures. Specific warranty
accruals may be made if unforeseen technical problems arise. If actual
experience, relative to these factors, adversely differs from these estimates,
additional warranty expense may be required.




     The table below shows the roll forward of warranty reserves for the year
ended December 31, 2003, and three months ended March 31, 2004 (in thousands):

     Statements of Cash Flows

     During the three months ended March 31, 2004, and year ended December 31,
2003, the funding requirements of the DSG Businesses and the Company were
combined. As the DSG Businesses have historically been managed as a part of the
operations of the Company, outstanding cash balances have not been reflected on
the accompanying financial statements.

Note 7: Major Customers and Suppliers

     Costco, a major national retailer, accounted for approximately 28% of the
DSG Businesses sales in 2003. For the three months ended March 31, 2004, Costco
represented 29% of sales. Loss of this customer would have a material adverse
effect on the DSG Businesses' operations.

     Hitron, Inc., Sony, and Mitsubishi Digital were the DSG Businesses' major
suppliers for electronic video products during 2003,collectively representing
83% and 90% of purchases for 2003 and the three months ended March 31, 2004,
respectively. Loss of any of these suppliers could result in short-term supply
problems and a possible loss of sales.

Notes to Unaudited Pro Forma Consolidated Statement of Operations Adjustments

The Unaudited Pro Forma Consolidated Statement of Operations for the Year Ended
December 31, 2003 has been adjusted to reflect the following:

(1)  To adjust depreciation and amortization expense for the change in the basis
     of property and equipment and intangible assets as if the purchase of S&M
     and IVS had been completed on January 1, 2003, net of historical
     depreciation and amortization expense of S&M and IVS.

(2)  To eliminate intercompany administrative charges of $151,000 related
     directly to cost sharing arrangements provided by S&M and IVS's prior
     parent, which were terminated as a result of the purchase transaction.
     Certain administrative services were absorbed by excess capacity of the
     Registrant and the Registrant has not hired additional employees to perform
     these administrative services.

(3)  The Registrant's pro forma tax provision reflects an effective tax rate of
     36% considering federal and state income taxes and the effect of certain
     non-deductible costs principally related to the acquisitions consummated.

The Unaudited Pro Forma Consolidated Statement of Operations for the Three
Months Ended March 31, 2004 has been adjusted to reflect the following:

     and IVS had been completed on January 1, 2004, net of historical
     depreciation and amortization expense of S&M and IVS.

     directly to cost sharing arrangements provided by S&M and IVS's prior
     parent, which were terminated as a result of the purchase transaction.

Notes to Unaudited Pro Forma Consolidated Balance Sheet Adjustments

The unaudited Pro Forma Consolidated Balance Sheet as of March 31, 2004 has been
adjusted to reflect the following:


(1)  On July 1, 2004, Mace Security International, Inc., a Delaware corporation
     (the "Company" or "Registrant"), through its wholly owned subsidiary, Mace
     Security Products, Inc., acquired substantially all of the operating assets
     of two operating divisions, namely, Industrial Vision Source(R) ("IVS") and
     SecurityandMore(R) ("S&M"), of MDI Operating, L.P., a wholly owned
     subsidiary of American Building Control, Inc. The asset acquisition was
     pursuant to the terms of an Agreement for Purchase and Sale of Assets dated
     June 21, 2004 (collectively the "Agreement"), by and among the Registrant,
     MDI Operating, L.P., and American Building Control, Inc. (the "Sellers").
     The assets (the "Purchased Assets") include substantially all of the assets
     of the Sellers used in the business of operating S&M and IVS, which are a
     supplier of "do-it-yourself" video surveillance and security equipment and
     a distributor of technological advanced imaging components and video
     equipment, respectively. Pursuant to the Agreement, Registrant purchased
     the assets for cash consideration totaling $5,621,000. The allocation of
     the purchase price is preliminary. The actual allocation will be based on
     management's final evaluation of the assets and liabilities acquired. For
     purposes of these pro forma financial statements, the excess of the
     purchase price over the fair value of the identifiable tangible and
     intangible assets was allocated to goodwill; however, this excess may
     ultimately be allocated to other specific tangible and intangible assets.
     The final allocation of the purchase price and the resulting effect on
     operations may differ significantly from the pro forma amounts included
     herein. The preliminary allocation of the purchase price is as follows:


         Current assets............................................. $3,230,000

         Property and equipment......................................   100,000

         Goodwill....................................................   368,000

         Other intangible assets..................................... 2,173,000
         Current liabilities assumed................................. ( 250,000)
                                                                     -----------

                                                                     $5,621,000
                                                                     ===========
