REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM



To the Board of Directors and Stockholder
G. Marks Hardware, Inc.

We have audited the accompanying balance sheets of G. Marks Hardware, Inc. (an
"S" Corporation) as of July 31, 2008 and 2007, and the related statements of
income, stockholders' equity and cash flows for the years then ended. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

We conducted our audits 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 audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of G. Marks Hardware, Inc. as of
July 31, 2008 and 2007, and the results of its operations and its cash flows for
the years then ended, in conformity with accounting principles generally
accepted in the United States of America.

As discussed in Note 10 to the financial statements, on August 18, 2008,
substantially all of the Company's assets have been acquired for an aggregate
purchase price of $25,000,000, including the repayment of $1,000,000 of bank
debt and the assumption of current liabilities.

G. MARKS HARDWARE, INC.
NOTES TO FINANCIAL STATEMENTS

Note 1 -   Nature of operations:

           G. Marks Hardware, Inc. (the "Company") (an "S" Corporation) is
           engaged in the manufacturing and sale of door locks and decorative
           hardware to locksmiths, wholesale distributors and door manufacturers
           throughout the United States. The Company's manufacturing facility
           and principal place of business is located in Amityville, New York.

Note 2 -   Summary of significant accounting policies:

           Revenue recognition:
           Revenue is recognized when products are shipped to customers. The
           Company believes that the shipment date is the most appropriate point
           in time indicating the completion of the earnings process because it
           does not have any post-shipment obligations, the product price is
           fixed and determinable and the collection of the resulting receivable
           is probable.

           Cash and cash equivalents:
           Cash and cash equivalents include all cash balances and highly liquid
           securities with original maturities of three months or less when
           acquired.

           Accounts receivable:
           Accounts receivable from the sale of door locks and decorative
           hardware are based on standard prices. The Company provides an
           allowance for doubtful accounts, which is based upon a review of
           outstanding receivables, historical collection information, and
           existing economic conditions. Accounts receivable are due 30 days
           after issuance of the invoice. Accounts receivable past due more than
           60 days are considered delinquent. Delinquent receivables are
           written-off based on individual credit evaluation and specific
           circumstances of the customer.

           Inventory:
           Inventory, consisting primarily of raw materials for the production
           of door locks and decorative hardware, is valued at the lower of cost
           or market, determined on a first-in, first-out basis.

           Equipment and leasehold improvements:
           Equipment and leasehold improvements are stated at cost. Depreciation
           is computed over the estimated useful lives of the assets using the
           straight-line method. Leasehold improvements are amortized using the
           straight-line method over the lesser of the estimated useful lives of
           the assets or the lease term. Expenditures for repairs and
           maintenance are charged to operations in the period incurred.

           Domestic purchases of tools and dies are capitalized and depreciated
           over their estimated useful lives. Tools and dies purchased by
           foreign suppliers on behalf of the Company are charged to operations
           in the period purchased, as their estimated useful life is not
           determinable due to the uncertainty of turnover of foreign suppliers.
           There were no significant tools and dies purchased from foreign
           suppliers during the year.

           Advertising:
           Advertising expense, which consists of trade shows, catalogs and
           direct mailings, is expensed as incurred. Advertising expense for the
           years ended July 31, 2008 and 2007 was $310,388 and $187,698,
           respectively.

           Shipping expenses:
           Shipping and handling expense, which consists of shipping supplies,
           trucking expenses and freight out, is expensed as incurred and
           included on the statements of income as operating expenses, under the
           caption, "Shipping". Shipping expense for the years ended July 31,
           2008 and 2007 was $668,459 and $519,348, respectively.

G. MARKS HARDWARE, INC.
NOTES TO FINANCIAL STATEMENTS

           Summary of significant accounting policies (continued):

           Income taxes:
           The Company has elected, and the stockholder has consented, under the
           applicable provisions of the Internal Revenue and New York State
           Franchise Tax Codes, to have the Company report its income for
           Federal Corporation and New York State Franchise tax purposes as an
           "S" Corporation. The stockholders report their respective shares of
           the net taxable income or loss on their personal tax returns.
           Therefore, no provision is made for Federal Corporation or New York
           State Franchise Taxes, except for the New York State tax imposed on
           "S" Corporations, when applicable.

           As an "S" Corporation with a non-calendar fiscal year-end, the
           Company is obligated under the Internal Revenue Code, to make
           "required payments" to the government representing the tax that would
           otherwise be due from the stockholder had the Company used a calendar
           year end. These payments are held on deposit by the Internal Revenue
           Service and are adjusted annually based upon the Company's reported
           taxable income or loss. At July 31, 2008 and 2007, the Company had
           tax deposits with the Internal Revenue Service in the amount of
           $439,420 and $272,768, respectively, which are included in the
           balance sheets under the caption "Deposits".

           Use of estimates:
           The preparation of financial statements in conformity with accounting
           principles generally accepted in the United States of America
           requires management to make estimates and assumptions that affect the
           reported amounts of assets and liabilities and disclosure of
           contingent assets and liabilities at the date of the financial
           statements and the reported amounts of revenues and expenses during
           the reporting period. The accounting estimates that require
           management's most difficult and subjective judgments include
           provisions for bad debts, inventory valuation, depreciable lives,
           impairment of long-lived assets and other reserves. Because of the
           uncertainty in such estimates, actual results may differ from these
           estimates.

           Recent accounting pronouncements:
           In September 2006, the FASB issued SFAS No. 157, Fair-Value
           Measurements ("SFAS No. 157"), which defines fair value, establishes
           guidelines for measuring fair value and expands disclosures regarding
           fair value measurements. SFAS No. 157 does not require any new fair
           value regarding fair value measurements but rather eliminates
           inconsistencies in guidance found in various prior accounting
           pronouncements. SFAS No. 157 is effective for fiscal years beginning
           after November 15, 2007. Management is evaluating the impact of SFAS
           No. 15, effective January 1, 2008, but does not currently expect the
           adoption of SFAS No. 157 to have a material impact on the financial
           condition and results of operations.

           On February 15, 2007, the FASB issued SFAS NO. 159, "The Fair Value
           Option for Financial Assets and Financial Liabilities - Including an
           Amendment of FASB Statement No. 115" ("SFAS 159"). This standard
           permits an entity to measure financial instruments and certain other
           items at estimated fair value. Most of the provisions of SFAS No. 159
           are elective; however, the amendment to FASB No. 115, "Accounting for
           Certain Investments in Debt and Equity Securities," applies to all
           entities that own trading an available-for-sale securities. The fair
           value option created by SFAS 159 permits an entity to measure
           eligible items at fair value as of specified election dates. The fair
           value option (a) may generally be applied instrument by instrument,
           (b) is irrevocable unless a new election date occurs, and (c) must be
           applied to the entire instrument and not to only a portion of the
           instrument. SFAS 159 is effective for years beginning after November
           15, 2007. Management is currently evaluating the impact of SFAS 159,
           if any, on the Company's financial statements.

Note 3 -   Inventories:

G. MARKS HARDWARE, INC.
NOTES TO FINANCIAL STATEMENTS

Note 4 -   Line of credit:

           At July 31, 2008 and 2007, the Company has a $3,000,000 line of
           credit agreement with a bank available for working capital loans,
           letters of credit and acceptances. At July 31, 2008 and 2007, the
           Company has outstanding loans payable of $1,000,000 and $0,
           respectively. The line of credit expires on January 15, 2009.

           Borrowings under the line of credit bear interest at LIBOR plus 1.5%.
           Borrowings are collateralized by substantially all of the Company's
           assets and a personal guarantee by the Company's Stockholder.

           In connection with the sale of substantially all of the Company's
           assets (see Note 10), the above loan was paid in full.

Note 5 -   Concentration risks:

           Credit risk:
           The Company maintains its cash in one financial institution. The
           balance is insured by the Federal Deposit Insurance Corporation up to
           $100,000. From time to time, the Company's balance may exceed this
           limit. At July 31, 2008 and 2007, the uninsured cash balance is
           approximately $879,000 and $267,000, respectively. The Company limits
           its credit risk by selecting financial institutions considered to be
           highly creditworthy.

           Customers:
           Trade accounts receivable are due primarily from locksmiths,
           wholesale distributors and door manufacturers. The Company does not
           require collateral; however, it performs ongoing credit evaluations
           of customer accounts. At both July 31, 2008 and 2007, approximately
           44% of trade accounts receivable was due from three customers.

           Direct labor:
           The Company's direct labor is covered by a union, which has a
           collective bargaining agreement due to expire in December 2008. The
           Company's past experience was favorable with respect to resolving
           conflicting demands with this union and none has had a significant
           effect on the Company's financial statements. Although management
           expects that there will initially be some differences between the
           Company and the union demands, management believes it is very
           unlikely that those differences will result in a protracted conflict.

           The Company does not contribute to a union pension plan.

Note 6 -   401(k) profit-sharing plan:

           The Company maintains a 401(k) profit sharing plan which covers
           substantially all employees. Employer contributions are
           discretionary. Eligible employees may make pre-tax contributions to
           the plan. For the years ended July 31, 2008 and 2007, employer
           contributions in the amount of $30,104 and $29,958, respectively,
           were charged to operations.

Note 7 -   Lease commitments:

           As of July 31, 2008, the Company leased automobiles under
           noncancelable operating leases expiring through January 2011. Lease
           expense charged to operations for the years ended July 31, 2008 and
           2007 were $42,195 and $35,495, respectively.

           Future minimum rental payments under lease agreements are as follows:

                July 31,                                              Amount

NOTES TO FINANCIAL STATEMENTS

Note 8 -   Contingencies:

           Guarantees:
           The Company guaranteed a mortgage obligation of its stockholder which
           is collateralized by the stockholder's building in which the Company
           operates its business (see Note 9). At July 31, 2008, $81,530
           remained outstanding to a bank under this obligation.

           In addition, the Company guaranteed a second mortgage on the building
           payable to the New York Job Development Authority. On August 8, 2002,
           the Company's stockholder refinanced the remaining balance on this
           mortgage by obtaining a promissory note in the amount of $600,000
           payable to a bank in monthly installments commencing on October 1,
           2002. The loan bears interest at LIBOR plus 1.5%. At July 31, 2008,
           $112,902 remained outstanding under this second mortgage.

           In connection with the sale of substantially all of the Company's
           assets (see Note 10), the above obligations were paid in full by the
           stockholder.

           Letters of credit:
           There were no outstanding commercial letters of credit at July 31,
           2008 and 2007 (see Note 4).

           Legal proceedings:
           The Company is, from time to time, involved in litigation incidental
           to the conduct of its business. However, the company is not party to
           any lawsuit or proceeding which, in the opinion of management is
           likely to have a material adverse effect on its financial condition.


Note 9 -   Related party transactions:

           Loan receivable - employee:
           At July 31, 2007, the Company has a loan receivable from an employee
           who is a relative of the Company's stockholder in the amount of
           $10,000. The loan was noninterest bearing and has no set repayment
           terms. The receivable was settled during the year ended July 31,
           2008.

           Operating lease:
           The Company leases, on month to month basis, land and a building for
           its operations from its stockholder (see Note 8). Rent expense for
           the year ended July 31, 2008 amounted to $292,800 of which
           approximately $228,700 was charged to cost of goods sold and $64,100
           was charged to operations. Building expenses for the year ended July
           31, 2008 (including real estate taxes) due under the lease amounted
           to approximately $259,900 of which approximately $203,000 was charged
           to cost of goods sold and $56,900 was charged to operations.


Note 10 -  Subsequent event:

           On August 18, 2008, Napco Security Systems, Inc., a diversified
           manufacturer of security products, encompassing intrusion and fire
           alarms, building access control systems and electronic locking
           devices, acquired substantially all of the assets of the Company for
           an aggregate purchase price of $25,000,000, including the repayment
           of $1,000,000 of bank debt and the assumption of current liabilities.

           At the date of acquisition, $21,500,000 was received in cash and
           $3,500,000 of the purchase price was placed in escrow. The
           distribution of the escrow balance is scheduled at various dates
           until December 31, 2009, subject to adjustment for, among other
           things, non-performance of certain milestones, such as turnover of
           accounts receivable and inventories.

(b)  PRO-FORMA FINANCIAL INFORMATION (UNAUDITED)

         Unaudited Consolidated Pro-forma Financial Information       F-13



The following unaudited consolidated pro-forma financial data have been derived
from the historical financial statements of Napco Security Systems, Inc.
("Napco") for the fiscal year ended June 30, 2008 G. Marks Hardware, Inc.
("Marks") as of and for the fiscal year ended July 31, 2008. The unaudited
consolidated pro-forma balance sheet gives effect to the Purchase Transaction as
if it had occurred on June 30, 2008. The unaudited consolidated pro-forma
statements of income for the fiscal year ended June 30, 2008 give effect to the
Purchase Transaction as if it had occurred at the beginning of the period
presented. The pro-forma adjustments are based upon available information and
certain assumptions that management believes are reasonable and are described in
the notes accompanying the unaudited consolidated pro-forma financial
statements. The unaudited consolidated pro-forma financial data do not purport
to represent what our results of operations or financial position would have
been had the Purchase Transaction occurred on the dates indicated, or to project
our results of operations or financial position for any future period or date,
nor does it give effect to any matters other than those describe in the notes
thereto. The Purchase Transaction will be accounted for as a purchase for
financial accounting purposes.

Pursuant to the purchase method of accounting, the total estimated purchase
price, in these unaudited pro-forma consolidated financial statements, has been
allocated to assets acquired and liabilities assumed based on a preliminary
determination by Napco's management. The difference between the fair value of
the consideration issued and the liabilities assumed and the fair value of the
identifiable tangible and intangible assets acquired has been recorded as
goodwill. These allocations are subject to change pending a final valuation of
certain fixed assets acquired as well as a potential purchase price adjustment
related to a subsequent measurement of the collectibility of receivables and
sale of inventory. As such, these allocations may differ from the information
presented herein.
