                  NAPCO SECURITY SYSTEMS, INC AND SUBSIDIARIES
        NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

1.)  Summary of Significant Accounting Policies and Other Disclosures

     The accompanying Condensed Consolidated Financial Statements are unaudited.
     In  management's  opinion,  all  adjustments  (consisting  of  only  normal
     recurring  accruals)  necessary for a fair presentation have been made. The
     results  of  operations  for  the  period  ended  March  31,  2007  are not
     necessarily  indicative  of  results  that may be  expected  for any  other
     interim period or for the full year.

     The  unaudited  Condensed  Consolidated  Financial  Statements  include the
     accounts  of  Napco  Security  Systems,  Inc.  and all of its  wholly-owned
     subsidiaries.  The Company has also consolidated a 51%-owned joint venture.
     The 49%  interest,  owned  by a  third  party,  is  reflected  as  minority
     interest.  All inter-company balances and transactions have been eliminated
     in consolidation.

     The Company has made a number of estimates and assumptions  relating to the
     assets and liabilities, the disclosure of contingent assets and liabilities
     and the  reporting  of revenues  and  expenses to prepare  these  financial
     statements in conformity with accounting  principles  generally accepted in
     the United States. Actual results could differ from those estimates.

     The unaudited Condensed Consolidated Financial Statements should be read in
     conjunction  with the Consolidated  Financial  Statements and related notes
     contained in the  Company's  Annual  Report on Form 10-K for the year ended
     June 30, 2006. The accounting  policies used in preparing  these  unaudited
     Condensed  Consolidated  Financial  Statements  are  consistent  with those
     described in the June 30, 2006 Consolidated Financial Statements.  However,
     for interim financial statements,  inventories are calculated using a gross
     profit percentage.

     Seasonality

     The  Company's  fiscal  year  begins  on  July  1  and  ends  on  June  30.
     Historically,  the end  users  of  Napco's  products  want to  install  its
     products prior to the summer;  therefore  sales of its products peak in the
     period April 1 through June 30, the Company's  fiscal fourth  quarter,  and
     are reduced in the period July 1 through September 30, the Company's fiscal
     first  quarter.  To a lesser  degree,  sales in Europe  are also  adversely
     impacted in the Company's first fiscal quarter because of European vacation
     patterns,  i.e., many  distributors and installers are closed for the month
     of August.

     Advertising and Promotional Costs

     Advertising  and  promotional  costs are included in "Selling,  General and
     Administrative" expenses in the Condensed Consolidated Statements of Income
     and are  expensed as  incurred.  Advertising  expense for the three  months
     ended  March 31, 2007 and 2006 was  $402,000  and  $180,000,  respectively.
     Advertising  expense for the nine months  ended March 31, 2007 and 2006 was
     $1,100,000  and $772,000,  respectively.  The  significant  increase in the
     current year is due to a major  tradeshow  occurring in March of 2007.  The
     same tradeshow occurred in April 2006 last fiscal year.

     Research and Development Costs

     Research  and  development  costs  are  included  in Cost of  Sales  in the
     Condensed  Consolidated  Statements of Income and are expensed as incurred.
     Research and Development  expense for the three months ended March 31, 2007
     and  2006  was  $1,325,000  and  $1,286,000,   respectively.  Research  and
     Development  expense for the nine months  ended March 31, 2007 and 2006 was
     $3,938,000 and $3,690,000, respectively.

     Business Concentration and Credit Risk

     An entity is more  vulnerable  to  concentrations  of credit  risk if it is
     exposed to risk of loss greater than it would have had if it mitigated  its
     risk through  diversification  of  customers.  Such risks of loss  manifest
     differently,  depending  on the  nature of the  concentration,  and vary in
     significance.  The Company has two major  customers with Sales and Accounts
     Receivable as follows (in thousands):

     These customers sell primarily  within North America.  Although  management
     believes that these customers are sound and creditworthy,  a severe adverse
     impact on their business  operations  could have a  corresponding  material
     adverse  effect on the Company's net sales,  cash flows,  and/or  financial
     condition.  In the ordinary course of business, the Company has established
     an allowance for doubtful accounts and customer deductions in the amount of
     $340,000 and $420,000 as of March 31, 2007 and June 30, 2006, respectively.
     The decrease in this allowance  related  primarily to the Company's  recent
     history of lower bad debt write-offs.  The allowance for doubtful  accounts
     is a subjective  critical estimate that has a direct impact on reported net
     earnings.   This  allowance  is  based  upon  the  evaluation  of  accounts
     receivable aging, specific exposures and historical trends.

     Stock Options

     During the three and nine months ended March 31, 2007 the Company granted 0
     and 66,500 stock options,  respectively,  under its 2002 Employee Incentive
     Stock Option Plan.  These grants have  exercise  prices  between  $6.02 and
     $6.62,  a fair market  value of  $259,000  and vest over a four year period
     from the date of grant.  No options were  exercised  under this plan during
     the three months ended March 31, 2007. 139,860 options were exercised under
     this plan with proceeds of $168,000  during the nine months ended March 31,
     2007.

     During the three and nine months  ended March 31, 2007 the Company  granted
     30,000 options under its 2000 Non-employee  Stock Option Plan. These grants
     have an exercise  price of $5.03,  a fair market  value of $94,800 and vest
     over a four year period from the date of grant.  No options were  exercised
     under this plan during the three or nine months ended March 31, 2007.

     The fair value of each  option  granted  during  the first  nine  months of
     fiscal  2007 was  estimated  on the date of grant  using the  Black-Scholes
     option-pricing model with the following weighted average assumptions:

     Risk-free interest rates             4.7%
     Expected lives                    7.15 years
     Expected volatility                   59%
     Expected dividend yields               0%


     Stock Dividend

     On May 10, 2006 the Company's  Board of Directors  approved a 3-for-2 stock
     split of its common stock,  to be paid in the form of a 50% stock  dividend
     to stockholders of record on May 24, 2006. The Company delivered the shares
     on June 7, 2006. Upon  completion of the split,  the total number of shares
     of common stock  outstanding  increased  from  approximately  13,300,000 to
     approximately 19,950,000.

                                       8


     All share and per share amounts (except par value) have been  retroactively
     adjusted  to  reflect  the stock  split.  There was no net  effect on total
     stockholders' equity as a result of this transaction.

     Recent Accounting Pronouncements

     In June 2006, the Financial  Accounting  Standards  Board  ("FASB")  issued
     Statement of Financial Accounting Standards ("SFAS")  Interpretation No. 48
     ("FIN 48"), "Accounting for Uncertainty in Income Taxes - An Interpretation
     of FASB Statement No. 109". FIN 48 clarifies the accounting for uncertainty
     in income taxes  recognized  in an  enterprise's  financial  statements  in
     accordance  with  SFAS  No.  109,   "Accounting  for  Income  Taxes".  This
     Interpretation prescribes a recognition threshold and measurement attribute
     for the financial  statement  recognition and measurement of a tax position
     taken or  expected to be taken in a tax return.  This  Interpretation  also
     provides   guidance  on   de-recognition,   classification,   interest  and
     penalties,  accounting in interim periods,  disclosure, and transition. FIN
     48 is effective for financial  statements issued for fiscal years beginning
     after December 15, 2006. The Company is currently  evaluating the impact of
     the application of FIN 48.

     In September 2006, the FASB issued SFAS No. 157, "Fair Value Measurements".
     SFAS No. 157 provides  guidance for using fair value to measure  assets and
     liabilities.  In addition, this statement defines fair value, establishes a
     framework  for measuring  fair value,  and expands  disclosures  about fair
     value  measurements.   Where  applicable,  this  statement  simplifies  and
     codifies related guidance within generally accepted accounting  principles.
     This  statement is effective  for  financial  statements  issued for fiscal
     years  beginning  after November 15, 2007, and interim periods within those
     fiscal  years.  The  Company's  adoption of SFAS No. 157 is not expected to
     have a material effect on its condensed consolidated financial statements.

     In September  2006, the SEC issued Staff  Accounting  Bulletin  ("SAB") No.
     108,  "Considering the Effects of Prior Year Misstatements when Quantifying
     Misstatements  in Current  Year  Financial  Statements"  ("SAB No. 108") to
     provide  guidance  on  the  consideration  of the  effects  of  prior  year
     misstatements in quantifying  current year misstatements for the purpose of
     a materiality  assessment.  Under SAB No. 108,  companies should evaluate a
     misstatement  based on its impact on the current year income statement,  as
     well as the cumulative effect of correcting such misstatements that existed
     in prior years existing in the current year's ending balance sheet. SAB No.
     108 will  become  effective  for the Company in its fiscal year ending June
     30,  2007.  The  Company's  adoption of SAB No. 108 did not have a material
     impact on its condensed consolidated financial statements.

     In February  2007, The FASB issued SFAS No. 159, "The Fair Value Option for
     Financial Assets and Financial Liabilities".  SFAS No. 159 permits entities
     to choose to measure many financial  instruments and certain other items at
     fair value.  The objective is to improve  financial  reporting by providing
     entities with the opportunity to mitigate  volatility in reported  earnings
     caused by measuring  related  assets and  liabilities  differently  without
     having to apply complex hedge accounting provisions. Most of the provisions
     of this Statement  apply only to entities that elect the fair value option.
     However, the amendment to SFAS No. 115, "Accounting for Certain Investments
     in  Debt  and   Equity   Securities",   applies   to  all   entities   with
     available-for-sale   and  trading   securities.   Some  requirements  apply
     differently  to entities  that do not report net income.  SFAS No. 159 will
     become  effective  for the Company in its fiscal year ending June 30, 2009.
     The  Company's  adoption of SFAS No. 159 is not expected to have a material
     effect on its condensed consolidated financial statements.

2.)  Stock-based Compensation

     The Company has established  two share  incentive  programs as discussed in
     more detail in the  Consolidated  Financial  Statements  and related  notes
     contained in the  Company's  annual  report on Form 10-K for the year ended
     June 30, 2006.  Prior to fiscal  2006,  the Company  applied the  intrinsic
     value method as outlined in  Accounting  Principles  Board  Opinion No. 25,
     "Accounting  for Stock  Issued to  Employees,"  ("APB No.  25") and related
     interpretations  in  accounting  for stock  options and share units granted
     under these  programs.  Under the intrinsic  value method,  no compensation
     expense was recognized if the exercise price of the Company's stock options
     equaled the market price of the underlying  stock on the date of the grant.
     Stock-based  compensation costs of $107,000 and $197,000 were recognized in
     three  months  ended  March 31,  2007 and 2006,  respectively.  Stock-based
     compensation  costs of $336,000 and $312,000 were recognized in nine months
     ended March 31, 2007 and 2006, respectively.

3.)  Inventories

                                                March 31,    June 30,
     Inventories consist of (in thousands):       2007        2006
                                                ---------   ---------

                        Finished products           9,164       6,538
                                                ---------   ---------
                                                $  31,784   $  22,666
                                                =========   =========

     For interim financial statements,  inventories are calculated using a gross
     profit   percentage.   In  addition,   the  Company  records  an  inventory
     obsolescence  reserve,  which represents the difference between the cost of
     the  inventory and its estimated  market  value,  based on various  product
     sales   projections.   This  reserve  is  calculated   using  an  estimated
     obsolescence  percentage applied to the inventory based on age,  historical
     trends and requirements to support  forecasted  sales. As of March 31, 2007
     and June 30,  2006,  balances in these  reserves  amounted to $836,000  and
     $987,000,  respectively.  In addition,  and as  necessary,  the Company may
     establish specific reserves for future known or anticipated events.

4.)  Earnings Per Common Share

     The Company  follows the provisions of SFAS No. 128,  "Earnings Per Share".
     In accordance with SFAS No. 128,  earnings per common share amounts ("Basic
     EPS") were computed by dividing  earnings by the weighted average number of
     common  shares  outstanding  for the  period.  Earnings  per  common  share
     amounts, assuming dilution ("Diluted EPS"), were computed by reflecting the
     potential  dilution  from the  exercise  of  stock  options.  SFAS No.  128
     requires the  presentation of both Basic EPS and Diluted EPS on the face of
     the condensed consolidated statements of income.

     A  reconciliation  between the numerators and denominators of the Basic and
     Diluted EPS  computations  for earnings is as follows (in thousands  except
     per share data) (Information reflects the stock splits as described in Note
     1):

5.)  Long Term Debt

     The  Company's  primary  source of  financing is an  $18,000,000  revolving
     credit agreement,  secured by all the accounts receivable,  inventory,  the
     Company's  headquarters in Amityville,  New York,  common stock of three of
     the  Company's  subsidiaries  and certain  other  assets of Napco  Security
     Systems,  Inc. The revolving  credit agreement bears interest at either the
     Prime Rate less 1/4% or an  alternate  rate based on LIBOR as  described in
     the agreement.  The agreement  contains various  restrictions and covenants
     including, among others, restrictions on payment of dividends, restrictions
     on borrowings,  restrictions  on capital  expenditures,  the maintenance of
     minimum  amounts of tangible net worth,  and compliance  with other certain
     financial ratios, as defined in the agreement.  The agreement currently has
     an expiration date of September 2008 and any outstanding  borrowings are to
     be repaid or refinanced on or before that time.  The Company has received a
     written  commitment from its bank to amend  the agreement to provide for an
     increase to $25,000,000  and extension of the expiration  date to September
     2011. The Company  anticipates  executing this amendment  prior to June 30,
     2007.

     Kingdom.  There were no sales into any one foreign country in excess of 10%
     of Net Sales.
     (2) Consists  primarily  of  inventories  and fixed  assets  located at the
     Company's principal manufacturing facility in the Dominican Republic.

7.)  Commitments and Contingencies

     In December  2004,  the Company  became a  defendant  in a product  related
     lawsuit, in which the plaintiff seeks damages of approximately  $1,500,000.
     This action is being defended by the Company's  insurance company on behalf
     of the Company.  Management  believes  that the action is without merit and
     plans to have this action vigorously defended.

     In the normal  course of business,  the Company is a party to claims and/or
     litigation.  Management  believes that the settlement of such claims and/or
     litigation,  considered in the aggregate,  will not have a material adverse
     effect on the Company's financial position and results of operations.

8.)  Income Taxes

     In March 2003,  Napco Security  Systems,  Inc.  timely filed its income tax
     return for the fiscal year ended June 30,  2002.  This  return  included an
     election to treat one of the Company's foreign  subsidiaries,  Napco DR, as
     if it were a domestic corporation beginning July 1, 2001. This election was
     based on a then recently enacted Internal Revenue Code ("Code")  provision.
     As a result of this election,  Napco DR is treated,  for Federal income tax
     purposes,  as transferring  all of its assets to a domestic  corporation in
     connection with an exchange. Although this type of transfer usually results
     in the recognition of taxable income to the extent of any untaxed  earnings
     and  profits,  the Code  provision  provides an  exemption  for  applicable
     corporations.  The Company qualifies as an applicable  corporation pursuant
     to this Code section, and based on this Code exemption, the Company treated
     the transfer of  approximately  $27,000,000 of Napco DR's untaxed  earnings
     and profits as nontaxable.

     The  Internal  Revenue  Service  has  issued a Revenue  Procedure  which is
     inconsistent  with  the Code  exemption  described  above.  The Code is the
     actual law; a Revenue Procedure is the IRS's interpretation of the law. The
     Code has a higher level of authority than a Revenue  Procedure.  Management
     believes that it has appropriately  relied on the guidance in the Code when
     filing  its  income tax  return.  If  challenged,  the  Company  originally
     determined that the potential  liability would range from $0 to $9,450,000.
     However,  the Company also believes there are other mitigating factors that
     would  limit  the  amount  of the  potential  liability,  and as a  result,
     management  accrued a liability of  $2,243,000  as of June 30, 2002.  As of
     March 31, 2007,  $400,000 of this accrued liability was no longer required.
     The Company reduced this accrued liability  accordingly in March 2007 which
     reduced the Company's  effective tax rate from  approximately 36% to 0% and
     26% for the three and nine months ended March 31, 2007. The Company expects
     to  eliminate  the balance in fiscal  2008.  The  Company's  tax  provision
     utilizes  estimates made by management and as such, is subject to change as
     described in Note 1 of the Consolidated  financial  statements  included in
     the Company's Form 10-K for the year ended June 30, 2006.

9.)  Treasury Stock

     On March 16,  2007,  the  Company  announced  that its  Board of  Directors
     authorized  the repurchase of up to one million  (1,000,000)  shares of its
     common stock.  As of March 31, 2007,  the Company has  repurchased  179,600
     shares at a weighted average price of $5.22 per share.  Subsequent to March


                                       12



     31, 2007,  the Company has  repurchased  an  additional  95,400 shares at a
     weighted average price of $5.74 per share.


Item 2. Management's Discussion and Analysis of Financial Condition and Results
        of Operations

Napco Security Systems, Inc.
Management's  Discussion  and  Analysis of  Financial  Condition  and Results of
Operations

This Quarterly Report on Form 10-Q and the information incorporated by reference
may include  "Forward-Looking  Statements"  within the meaning of Section 27A of
the  Securities  Act of 1933 and Section 21E of the  Exchange  Act of 1934.  The
Company intends the Forward-Looking  Statements to be covered by the Safe Harbor
Provisions  for  Forward-Looking   Statements.   All  statements  regarding  the
Company's  expected  financial  position  and  operating  results,  its business
strategy,  its  financing  plans  and  the  outcome  of  any  contingencies  are
Forward-Looking  Statements. The Forward-Looking Statements are based on current
estimates and  projections  about our industry and our  business.  Words such as
"anticipates,"  "expects," "intends," "plans," "believes," "seeks," "estimates,"
or  variations  of such words and similar  expressions  are intended to identify
such Forward-Looking  Statements.  The Forward-Looking Statements are subject to
risks and  uncertainties  that could cause actual  results to differ  materially
from those set forth or implied by any Forward-Looking  Statements. For example,
the Company is highly  dependent on its Chief  Executive  Officer for  strategic
planning.  If he is unable to perform his services for any significant period of
time, the Company's ability to continue growing could be adversely affected.  In
addition,  factors that could cause actual results to differ materially from the
Forward-Looking  Statements  include,  but  are  not  limited  to,  adverse  tax
consequences  of  offshore   operations,   distribution   problems,   unforeseen
environmental  liabilities  and the uncertain  military,  political and economic
conditions in the world.

Overview

The Company is a diversified  manufacturer  of security  products,  encompassing
intrusion  and fire  alarms,  building  access  control  systems and  electronic
locking   devices.   These  products  are  used  for  commercial,   residential,
institutional,  industrial and governmental applications, and are sold worldwide
principally  to  independent  distributors,  dealers and  installers of security
equipment.  International  sales accounted for approximately 16% of our revenues
for fiscal year 2006 and 14% for the first nine months of fiscal 2007.

The Company owns and operates manufacturing  facilities in Amityville,  New York
and the Dominican  Republic.  A significant  portion of our operating  costs are
fixed,  and do not fluctuate  with changes in customer  demand or utilization of
our  manufacturing   capacity.  As  production  rises  and  factory  utilization
increases,  the fixed  costs  are  spread  over  increased  output,  which has a
positive  impact on profit  margins.  Conversely,  when  production  and factory
utilization  decline  our fixed costs are spread over  reduced  levels,  thereby
having a negative impact on profit margins.

In February  2004 the Company  entered  into a joint  venture  with an unrelated
company to sell security-related  products,  including those manufactured by the
Company,  in the  Middle  East.  The  Company  owns 51% of the  company,  an LLC
organized  in New  York,  which  has its  main  operations  in the  United  Arab
Emirates.  Revenues generated by this joint venture were approximately 2% of our
revenues for fiscal 2006 and 2% for the first nine months of fiscal 2007.

The security products market is characterized by constant incremental innovation
in  product  design  and  manufacturing  technologies.  Generally,  the  Company
generally  devotes  7-8% of  revenues to research  and  development  (R&D) on an
annual basis.  Products  resulting  from our R&D  investments  in the first nine
months of fiscal 2007 did not  contribute  materially  to revenue  during fiscal
2007,  but should  benefit the  Company in future  years.  In  general,  the new
products  introduced by the Company are initially shipped in limited quantities,
and increase over time. Prices and manufacturing costs tend to decline over time
as products and technologies mature.

Economic and Other Factors

The post September 11 era has generally been  characterized  by increased demand
for electronic security products and services. The Company believes the security
equipment  market is likely to continue to exhibit healthy growth,  particularly
in  industrial  sectors,  due to ongoing  concerns over the adequacy of security
safeguards.

Seasonality

The  Company's  fiscal year begins on July 1 and ends on June 30.  Historically,
the end users of Napco's  products  want to install  its  products  prior to the
summer;  therefore sales of its products peak in the period April 1 through June
30, the Company's  fiscal fourth  quarter,  and are reduced in the period July 1
through  September 30, the Company's  fiscal first quarter.  To a lesser degree,
sales in Europe  are also  adversely  impacted  in the  Company's  first  fiscal
quarter  because of European  vacation  patterns,  i.e., many  distributors  and
installers are closed for the month of August.

Critical Accounting Policies

The discussion and analysis of our financial condition and results of operations
are based upon our condensed consolidated financial statements,  which have been
prepared in conformity  with  accounting  principles  generally  accepted in the
United States. The preparation of these financial statements requires us to make
estimates  and  assumptions   that  affect  the  reported   amounts  of  assets,
liabilities, revenues and expenses reported in those financial statements. These
judgments can be subjective and complex,  and consequently  actual results could
differ from those  estimates.  Our most critical  accounting  policies relate to
revenue recognition;  concentration of credit risk;  inventories;  goodwill; and
income taxes.

Revenue Recognition

Revenues from merchandise  sales are recorded at the time the product is shipped
or delivered to the  customer  pursuant to the terms of purchase.  We report our
sales  levels on a net sales basis,  which is computed by  deducting  from gross
sales the  amount of  actual  returns  received  and an amount  established  for
anticipated returns and allowances.

Our sales return  accrual is a subjective  critical  estimate  that has a direct
impact on reported net sales and income.  This accrual is calculated  based on a
history  of gross  sales  and  actual  sales  returns,  as well as  management's
estimate of anticipated returns and allowances.

Business Concentration and Credit Risk

An entity is more vulnerable to  concentrations  of credit risk if it is exposed
to risk of loss greater than it would have had if it mitigated  its risk through
diversification of customers. Such risks of loss manifest differently, depending
on the nature of the  concentration,  and vary in significance.  The Company has
two  major  customers  with  Sales  and  Accounts   Receivable  as  follows  (in
thousands):

These  customers  sell  primarily  within  North  America.  Although  management
believes  that these  customers  are sound and  creditworthy,  a severe  adverse
impact on their business operations could have a corresponding  material adverse
effect on the Company's net sales, cash flows,  and/or financial  condition.  In
the ordinary  course of business,  the Company has  established an allowance for
doubtful accounts and customer deductions in the amount of $340,000 and $420,000
as of March 31,  2007 and June 30,  2006,  respectively.  The  decrease  in this
allowance  related  primarily to the Company's  recent history of lower bad debt
write-offs.  The  allowance  for  doubtful  accounts  is a  subjective  critical
estimate that has a direct impact on reported net  earnings.  This  allowance is
based upon the evaluation of accounts  receivable aging,  specific exposures and
historical trends.

Inventories

We state our  inventory  at the lower of cost or fair  market  value,  with cost
being determined on the first-in,  first-out (FIFO) method. We believe FIFO most
closely  matches the flow of our products from  manufacture  through  sale.  The
reported  net  value  of our  inventory  includes  finished  saleable  products,
work-in-process  and raw materials that will be sold or used in future  periods.
Inventory cost includes raw materials, direct labor and overhead.

We  also  record  an  inventory   obsolescence  reserve,  which  represents  the
difference  between the cost of the inventory  and its  estimated  market value,
based on various product sales projections.  This reserve is calculated using an
estimated  obsolescence  percentage  applied  to the  inventory  based  on  age,
historical trends and requirements to support forecasted sales. In addition, and
as necessary, we may establish specific reserves for future known or anticipated
events.  For interim  financial  statements,  inventories are calculated using a
gross profit percentage.

Goodwill and Other Intangible Assets

Effective July 1, 2001, the Company  adopted  Statement of Financial  Accounting
Standards (SFAS) No. 141,  Business  Combinations and SFAS No. 142, Goodwill and
Other Intangible Assets. These statements  established  accounting and reporting
standards for acquired goodwill and other intangible assets.  Specifically,  the
standards address how acquired intangible assets should be accounted for both at
the time of  acquisition  and after they have been  recognized  in the financial
statements.  In  accordance  with SFAS No.  142,  intangible  assets,  including
purchased  goodwill,  must be evaluated for impairment.  Those intangible assets
that are classified as goodwill or as other  intangibles  with indefinite  lives
are not amortized.

Impairment  testing  is  performed  in two  steps:  (i) the  Company  determines
impairment  by  comparing  the fair value of a reporting  unit with its carrying
value,  and (ii) if there is an impairment,  the Company  measures the amount of
impairment  loss by  comparing  the  implied  fair  value of  goodwill  with the
carrying  amount  of  that  goodwill.  The  Company  has  performed  its  annual
impairment evaluation required by this standard and determined that its goodwill
is not impaired.

                                       15

Income taxes

Deferred income taxes are recognized for the expected future tax consequences of
temporary  differences between the amounts reflected for financial reporting and
tax purposes.  Net deferred tax assets are adjusted by a valuation allowance if,
based on the weight of available evidence,  it is more likely than not that some
portion or all of the net  deferred  tax  assets  will not be  realized.  If the
Company  determines  that a deferred tax asset will not be  realizable or that a
previously reserved deferred tax asset will become realizable,  an adjustment to
the deferred tax asset will result in a reduction  of, or increase to,  earnings
at that time. The provision for income taxes represents U.S. Federal,  state and
foreign taxes.  Through June 30, 2001, the Company's subsidiary in the Dominican
Republic,  Napco/Alarm  Lock Group  International,  S.A.  ("Napco DR"),  was not
subject  to tax in the  United  States,  as a result,  no taxes  were  provided.
Effective July 1, 2001, the Company made a domestication  election for Napco DR.
Accordingly,  its income is subject to taxation in the United  States on a going
forward basis.

In March 2003, Napco Security  Systems,  Inc. timely filed its income tax return
for the fiscal year ended June 30,  2002.  This  return  included an election to
treat  one of the  Company's  foreign  subsidiaries,  Napco  DR, as if it were a
domestic  corporation  beginning July 1, 2001. This election was based on a then
recently enacted Internal Revenue Code ("Code")  provision.  As a result of this
election,  Napco DR is treated, for Federal income tax purposes, as transferring
all of its assets to a domestic  corporation  in  connection  with an  exchange.
Although this type of transfer  usually  results in the  recognition  of taxable
income to the extent of any untaxed  earnings  and profits,  the Code  provision
provides an exemption for applicable  corporations.  The Company qualifies as an
applicable  corporation  pursuant to this Code  section,  and based on this Code
exemption,  the Company  treated the transfer of  approximately  $27,000,000  of
Napco DR's untaxed earnings and profits as nontaxable.

The  Internal   Revenue  Service  has  issued  a  Revenue   Procedure  which  is
inconsistent  with the Code exemption  described  above.  The Code is the actual
law; a Revenue Procedure is the IRS's  interpretation of the law. The Code has a
higher level of authority than a Revenue Procedure.  Management believes that it
has appropriately  relied on the guidance in the Code when filing its income tax
return.  If challenged,  the Company  originally  determined  that the potential
liability would range from $0 to $9,450,000.  However, the Company also believes
there are other mitigating  factors that would limit the amount of the potential
liability,  and as a result,  management accrued a liability of $2,243,000 as of
June 30, 2002. As of March 31, 2007,  $400,000 of this accrued  liability was no
longer required. The Company reduced this accrued liability accordingly in March
2007 which reduced the Company's effective tax rate from approximately 36% to 0%
and 26% for the three and nine months  ended March 31, 2007,  respectively.  The
Company  expects to eliminate  the balance in fiscal  2008.  The  Company's  tax
provision  utilizes  estimates  made by  management  and as such,  is subject to
change as described in Note 1 of the Consolidated  financial statements included
in the Company's Form 10-K for the year ended June 30, 2006.

Sales for the three months ended March 31, 2007 decreased by approximately 9% to
$15,566,000 as compared to $17,085,000 for the same period a year ago. Sales for
the  nine  months  ended  March  31,  2007  decreased  by  approximately  6%  to
$45,672,000  as compared  to  $48,488,000  for the same  period a year ago.  The
decrease  in sales for the three and nine  months was due to lower  sales in the
Company's  European  market as disclosed last quarter and sales of the Company's
burglar  alarm  products in the United  States  which  management  believes  was
impacted  by the  slowdown  in the  U.S.  housing  market.  These  factors  were
partially  offset by  higher  sales of the  Company's  access  control  and door
locking devices which also have higher average profit margins.

The Company's  gross profit for the three months ended March 31, 2007  decreased
by $862,000 to  $5,494,000  or 35.3% of sales as compared to $6,356,000 or 37.2%
of sales for the same period a year ago. The Company's gross profit for the nine
months  ended March 31, 2007  decreased by $652,000 to  $16,878,000  or 37.0% of
sales as  compared to  $17,530,000  or 36.2% of sales for the same period a year
ago. The decrease in gross profit for the three months was due  primarily to the
lower  sales for the  period as  partially  offset by a  positive  raw  material
pricing  variance.  The  increase  in gross  profit for the nine  months was due
primarily to the same factors  affecting the three months as well as a reduction
in the first fiscal quarter in the Company's inventory reserves of approximately
$150,000  and  increased  overhead  absorption   resulting  from  the  increased
production rate described below.

Selling,  general and  administrative  expenses for the three months ended March
31, 2007 increased by $194,000 to $4,226,000,  or 27.2% of sales, as compared to
$4,032,000,  or 23.6% of sales a year ago. Selling,  general and  administrative
expenses  for the nine  months  ended March 31,  2007  increased  by $515,000 to
$12,205,000,  or 26.7% of sales, as compared to $11,690,000, or 24.1% of sales a
year ago.  The  increase in dollars and as a  percentage  of sales for the three
months  ended  March 31,  2007 was due  primarily  to the  timing  of  tradeshow
expenses  relating to a major  tradeshow  which occurred in March 2007. The same
tradeshow occurred in April of 2006 in the prior year. The increase for the nine
months ended March 31, 2007 was due to the timing of these tradeshow expenses as
well as advertising of the Company's access control products, commission expense
related  to  increases  in  sales of the  Company's  door-locking  products  and
additional  expenses  relating to the  Company's  initial  audit of its internal
controls  required  by the  Sarbanes-Oxley  Act of 2002.  As fiscal 2006 was the
initial period requiring an audit by the Company's Independent Registered Public
Accounting Firm and that the opinion  expressed by them for that period was that
our assessment  that we maintained  effective  internal  controls over financial
reporting was fairly stated,  Management believes that these audit expenses will
be  reduced  for  fiscal  2007 as much of the  documentation  performed  for the
initial  assessment  and audit will be utilized  in  subsequent  periods.  These
increases were partially offset by a decrease in bad debt expense resulting from
the Company's recent history of lower bad debt write-offs.

Interest  expense,  net for the three months  ended March 31, 2007  increased by
$100,000  to  $168,000  as  compared  to $68,000 for the same period a year ago.
Interest  expense,  net for the nine months  ended March 31, 2007  increased  by
$211,000 to  $377,000  as  compared to $166,000  for the same period a year ago.
These increases  resulted  primarily from the increase in the Company's  average
outstanding debt, the result of the Company's increase in inventory as discussed
below,  as well as in interest rates as compared to those from the same period a
year ago.

The  Company's  provision  for income taxes for the three months ended March 31,
2006 decreased by $770,000 to $5,000 as compared to $775,000 for the same period
a year ago. The  Company's  provision for income taxes for the nine months ended
March 31, 2007 decreased by $854,000 to $1,150,000 as compared to $2,004,000 for
the same  period a year ago.  The tax  provision  for the three and nine  months
ended March 31, 2007 is calculated  using an estimated annual effective tax rate
of 36% and 35%, respectively. The decrease in provision for income taxes for the
three and nine months resulted from the decrease in Income before income tax. In
addition,  the  reduction  of an accrued  tax  liability,  as  discussed  above,
decreased the provision for the three and nine months by approximately $400,000.

Net income  decreased by $343,000 to  $1,132,000  or $0.06 per diluted share for
the three  months  ended March 31, 2007 as compared to  $1,475,000  or $0.07 per
diluted  share for the same period a year ago. Net income  decreased by $545,000
to  $3,228,000  or $0.16 per diluted  share for the nine months  ended March 31,
2007 as compared to  $3,773,000 or $0.18 per diluted share for the same period a
year ago. These decreases were primarily due to the aforementioned  decreases in
net sales and gross profit and increases in selling,  general and administrative
expenses, net of the related decrease in provision for income taxes.

Liquidity and Capital Resources

During the nine months ended March 31, 2007 the Company  utilized  $1,704,000 of
cash and $4,500,000 in additional borrowings to fund the cash used in operations
($4,474,000),  purchase  property,  plant and equipment  ($786,000) and treasury
stock  ($944,000).  One of the key factors in the use of operating  cash was our
investment  in  additional  inventory   ($9,118,000)  as  discussed  below.  The
Company's  management  believes that current  working  capital,  cash flows from
operations  and its revolving  credit  agreement  will be sufficient to fund the
Company's operations through at least the next twelve months.

                                       17


Accounts  Receivable at March 31, 2007  decreased  $2,810,000 to  $22,343,000 as
compared to $25,153,000 at June 30, 2006.  This decrease is primarily the result
of the higher sales volume during the quarter ended June 30, 2006 as compared to
the quarter ended March 31, 2007 as partially  offset by extended  terms granted
to certain of the  Company's  customers  during the quarter ended June 30, 2006.
Certain of these terms extended beyond March 31, 2007.

Inventories at March 31, 2007 increased by $9,118,000 to $31,784,000 as compared
to $22,666,000  at June 30, 2006.  This increase was primarily the result of the
Company  level-loading its production schedule in anticipation of its historical
sales cycle where a larger  portion of the  Company's  sales occur in the latter
fiscal  quarters  as  compared  to the  earlier  quarters  as well as  producing
additional inventory to support the introduction of the Company's new Freedom 64
code-less  intrusion  alarm system and several other key new products as well as
to support a projection  of higher sales in fiscal  2007.  Because  these levels
were not realized, during the third quarter of fiscal 2007 the Company initiated
several  steps  in order to  reduce  inventory  levels,  including  reduced  its
purchasing  levels,  manufacturing  labor and production output, and anticipates
realizing their full effectiveness in the coming quarters.

As of March 31, 2007, the Company's credit facility  consisted of an $18,000,000
secured revolving credit agreement. As of March 31, 2007 there was approximately
$8,800,000  available under the secured  revolving credit facility.  This credit
facility  currently  expires in  September  2008.  In April  2007,  the  Company
obtained a written  commitment  from it's bank to amend the agreement to provide
for an increase to $25,000,000 and extension of the expiration date to September
2011. The Company anticipates executing this amendment prior to June 30, 2007.

As of March  31,  2007 the  Company  had no  material  commitments  for  capital
expenditures  or inventory  purchases  other than purchase  orders issued in the
normal course of business.


ITEM 3:  Quantitative and Qualitative Disclosures About Market Risk

The Company's principal financial  instrument is long-term debt (consisting of a
revolving  credit  facility)  that  provides  for interest at a spread below the
prime rate.  The Company is affected by market risk exposure  primarily  through
the effect of changes in interest rates on amounts  payable by the Company under
this credit  facility.  At March 31,  2007,  an  aggregate  principal  amount of
approximately $9,200,000 was outstanding under the Company's credit facility. If
principal  amounts  outstanding  under the Company's credit facility remained at
this  quarter-end  level for an  entire  year and the prime  rate  increased  or
decreased,  respectively,  by 1% the Company would pay or save, respectively, an
additional $92,000 in interest that year.

A  significant   number  of  foreign  sales  transactions  by  the  Company  are
denominated in U.S.  dollars.  As such, the Company has shifted foreign currency
exposure onto many of its foreign customers. As a result, if exchange rates move
against foreign customers,  the Company could experience  difficulty  collecting
unsecured accounts  receivable,  the cancellation of existing orders or the loss
of future orders. The foregoing could materially  adversely affect the Company's
business,  financial  condition  and results of  operations.  In  addition,  the
Company transacts certain sales in Europe in British Pounds Sterling,  therefore
exposing  itself  to a certain  amount  of  foreign  currency  risk.  Management
believes that the amount of this exposure is immaterial.  We are also exposed to
foreign currency risk relative to expenses  incurred in Dominican Pesos ("RD$"),
the  local  currency  of the  Company's  production  facility  in the  Dominican
Republic.  The  result  of a 10%  strengthening  in the U.S.  dollar  to our RD$
expenses  would  result  in an annual  decrease  in income  from  operations  of
approximately $450,000.


ITEM 4:  Controls and Procedures

We maintain  disclosure controls and procedures that are designed to ensure that
information  required to be  disclosed  in our Exchange Act reports is recorded,
processed,  summarized  and reported  within the time  periods  specified in the
SEC's rules and forms, and that such information is accumulated and communicated
to our  management  to allow timely  decisions  regarding  required  disclosure.
Management  necessarily applied its judgment in assessing the costs and benefits
of such  controls  and  procedures,  which,  by their  nature,  can provide only
reasonable assurance regarding management's control objectives.

                                       18


At the  conclusion  of the  period  ended  March 31,  2007,  we  carried  out an
evaluation,  under the supervision and with the participation of our management,
including  our Chief  Executive  Officer  and Chief  Financial  Officer,  of the
effectiveness  of the  design  and  operation  of our  disclosure  controls  and
procedures.  Based upon that evaluation,  the Chief Executive  Officer and Chief
Financial  Officer  concluded that our disclosure  controls and procedures  were
effective in alerting  them in a timely  manner to  information  relating to the
Company required to be disclosed in this report.

During the third quarter of fiscal 2007,  there were no changes in the Company's
internal control over financial reporting that have materially affected,  or are
reasonably  likely to materially  affect,  the Company's  internal  control over
financial reporting.
