                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
           (Information with respect to interim periods is unaudited)

1.   Basis of Presentation

     The accompanying unaudited consolidated financial statements have been
     prepared in accordance with generally accepted accounting principles for
     interim financial information and with the instructions to Form 10-Q and
     Article 10 of Regulation S-X. Accordingly, they do not include all of the
     information and footnotes required by accounting principles generally
     accepted in the United States for complete financial statements. In the
     opinion of management, all adjustments (consisting of normal recurring
     accruals) considered necessary for a fair presentation have been included.
     Operating results for the three months ended September 30, 2004 are not
     necessarily indicative of the results that may be expected for the year
     ending June 30, 2005.

     The balance sheet at June 30, 2004 has been derived from the audited
     financial statements at that date, but does not include all of the
     information and footnotes required by generally accepted accounting
     principles for complete financial statements.

     For further information, refer to the consolidated financial statements and
     footnotes thereto included in the Company's Annual Report on Form 10-K for
     the year ended June 30, 2004.

2.   Net Income Per Share

     Basic income per common share excludes any dilution. It is based upon the
     weighted average number of common shares outstanding during the period.
     Dilutive earnings per share reflects the potential dilution that would
     occur if options to purchase common stock were exercised. The following
     table sets forth the reconciliation of weighted average shares outstanding
     and diluted weighted average shares outstanding:

     compensation under Accounting Principles Board Opinion No. 25, "Accounting
     for Stock Issued to Employees" and related interpretations. The Company has

The Financial Accounting Standards Board ("FASB") is expected to issue in the
fourth quarter of 2004 FASB Statement 123R, Share-Based Payment ("FAS 123R"). If
adopted as currently contemplated, FAS 123R would require all companies to
measure compensation cost for all share-based payments (including employee stock
options) at fair value and recognize such costs in the statement of operations.
FAS 123R would be effective for public companies for periods beginning after
June 15, 2005. Management is currently evaluating the impact of FAS 123R and has
not determined the impact of this statement on the consolidated financial
statements.

7.   Loans to Affiliate

Hearing Innovations, Inc.

During fiscal 2005, the Company entered into a loan agreement whereby Hearing
Innovations, Inc. ("Hearing Innovations") is required to pay the Company $16,720
due December 31, 2004. The note bears interest at 8% per annum. The note is
secured by a lien on all of Hearing Innovations' right, title and interest in
accounts receivable, inventory, property, plant and equipment and processes of
specified products whether now existing or arising after the date of this
agreement. The loan agreement contains warrants to acquire 16,720 shares of
Hearing Innovations common stock, at the option of the Company, at a cost of
$.20 per share. These warrants, which are deemed nominal in value, expire in
December 2005. The current ability of companies such as Hearing Innovations to
access capital markets or incur third party debt is very limited and is likely
to remain so for the foreseeable future. In light of this fact, Hearing
Innovations suspended operations in April 2004.

In connection with the adoption of FASB Interpretation 46 "Consolidation of
Variable Interest Entities, an Interpretation of ARB No. 51" ("FIN 46") the
Company consolidated Hearing Innovations in its March 31, 2004 balance sheet as
the entity was determined to be a variable interest entity ("VIE") and the
Company is its primary beneficiary. The Company elected to record the adoption
of FIN 46 as a cumulative effect of an accounting change. Consolidating Hearing
Innovations did not have a material impact on the Company's consolidated results
of operations or financial condition. Since Hearing Innovations, Inc. is now
consolidated, a loan of $16,720 for the three months ended September 30, 2004 is
eliminated in consolidation.

On July 14, 2004, Hearing Innovations sent all shareholders and creditors a plan
for reorganization and disclosure statement. The Company committed to fund
Hearing Innovations up to $150,000 for the reorganization plan. Hearing
Innovations plans to file for relief under Chapter 11 of the U.S. Bankruptcy
Code in November 2004. If the petition is approved, the Company will own 100% of
the equity in Hearing Innovations.

8.   Business Segments

The Company operates in two business segments which are organized by product
types: laboratory and scientific products and medical devices. Laboratory and
scientific products include the Sonicator ultrasonic liquid processor, Aura
ductless fume enclosure, the Labcaire Autoscope and Guardian

endoscope disinfectant systems and the Mystaire wet scrubber. Medical devices
include the Auto Sonix ultrasonic cutting and coagulatory system, refurbishing
revenues of high-performance ultrasound systems and replacement transducers for
the medical diagnostic ultrasound industry, ultrasonic lithotriptor, ultrasonic
neuroaspirator (used for neurosurgery) and soft tissue aspirator (used primarily
for the cosmetic surgery market). The Company evaluates the performance of the
segments based upon income from operations before general and administrative
expenses. The accounting policies of the segments are the same as those
described in the summary of significant accounting policies (Note 1) in the
Company's Annual Report on Form 10-K for the year ended June 30, 2004. Certain
items are maintained at the corporate headquarters (corporate) and are not
allocated to the segments. They primarily include general and administrative
expenses. The Company does not allocate assets by segment. Summarized financial
information for each of the segments are as follows:

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS


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

Three Months Ended September 30, 2004 and 2003.

NET SALES. Net sales of the Company's medical device products and laboratory and
scientific products increased $1,880,168 to $10,500,066 for the three months
ended September 30, 2004 from $8,619,898 for the three months ended September
30, 2003. This difference in net sales is due to an increase in sales of medical
device products of $1,328,553 to $5,930,673 for the three months ended September
30, 2004 from $4,602,120 for the three months ended September 30, 2003. This
difference in net sales is also due to an increase in sales of laboratory and
scientific products of $551,615 to $4,569,393 for the three months ended
September 30, 2004 from $4,017,778 for the three months ended September 30,
2003. The increase in sales of medical device products is due to an increase in
sales of diagnostic medical device products of $216,299 and an increase of
$1,112,254 in sales of therapeutic medical device products, both due to
increased customer demand for several diagnostic and therapeutic medical
products. The increase in sales for diagnostic medical device products was not
attributable to a single customer, distributor or any other specific factors.
The increase in sales for therapeutic medical device products was mostly
attributable to an increase in sales to United States Surgical Corporation
("USS") of approximately $542,000 and sales in Europe of the Sonablate 500
product of approximately $366,000. The remaining increase in therapeutic medical
device products is due to increased demand for several products. The increase in
laboratory and scientific products is due to an increase in Labcaire sales of
$144,979, sales of wet scrubber products of $404,110 and ductless fume enclosure
products of $22,208 partially offset by a decrease in laboratory ultrasonic
product sales of $19,682. The increase in Labcaire sales is primarily due to
demand for the Guardian (endoscopic cleaning) product. Export sales from the
United States are remitted in U.S. Dollars and export sales for Labcaire are
remitted in English Pounds. During the three months ended September 2004 and
2003, the Company had foreign net sales of $3,935,369 and $2,854,838,
respectively, representing 37.5% and 33.1% of net sales for such years,
respectively. The increase in foreign sales during the three months ended
September 30, 2004 as compared to the three months ended September 30, 2003 is
substantially due to increased sales of therapeutic medical device products in
Europe. In March 2004, the Company signed an exclusive distribution agreement
with Focus Surgery, Inc. ("Focus Surgery") for the sale of the Sonablate 500 for
the treatment of prostate cancer and other prostatic tumors in the geographic
areas of Western Europe, Eastern Europe and Russia. The agreement is for a term
of 2 years by the Company for automatic renewals for successive 1 year terms as
long as minimum quantities are purchased.

The Company's revenues are generated from various geographic regions. The
following is an analysis of net sales by geographic region:

       (A) Amount represents general and administrative expenses.

GROSS PROFIT: Gross profit decreased to 42.0% for the three months ended
September 30, 2004 from 42.5% for the three months ended September 30, 2003.
Gross profit for medical device products decreased to 43.1% of sales in the
three months ended September 30, 2004 from 44.6% of sales in the three months
ended September 30, 2003. The decrease in gross profit for medical device
products was negatively impacted by an unfavorable order mix for sales of
therapeutic medical device products, partially offset by an increase in
diagnostic medical device products. Gross profit for laboratory and

scientific products increased to 40.6% for the three months ended September 30,
2004 from 40.2% for the three months ended September 30, 2003. The increase in
gross profit for laboratory and scientific products is predominantly due to an
increase in gross margins for wet scrubber products due to increased volume. The
Company manufactures and sells both medical device and laboratory and scientific
products with a wide range of product costs and gross margin dollars as a
percentage of revenues.

SELLING EXPENSES: Selling expenses increased $483,276 to $1,439,809 for the
three months ended September 30, 2004 from $956,533 for the three months ended
September 30, 2003. Medical device products selling expenses increased $386,801
predominantly due to additional sales and marketing efforts for European
distribution of the Sonablate 500 product used to treat prostate cancer and
other prostatic afflictions. Laboratory and scientific selling expenses
increased $96,475 predominantly due to an increase in marketing expenses for
Labcaire's Guardian endoscopic cleaning product.

GENERAL AND ADMINISTRATIVE EXPENSES: General and administrative expenses
decreased $314,874 from $2,055,768 in the three months ended September 30, 2003
to $1,740,894 in the three months ended September 30, 2004. The decrease is
predominantly due to a decrease in the allowance for doubtful accounts,
specifically related to a reserve established against Focus Surgery which is no
longer needed, and reduced administrative costs in Labcaire principally due to
the prior fiscal year including one time severance costs.

RESEARCH AND DEVELOPMENT EXPENSES: Research and development expenses increased
$253,288 from $488,480 for the three months ended September 30, 2003 to $741,768
for the three months ended September 30, 2004. Medical device research and
development expenses increased $191,374 predominantly due to research and
development efforts for a product to treat liver and kidney cancer. Laboratory
and Scientific research and development expenses increased $61,914 predominantly
due to increased research and development efforts in various product
enhancements and new product designs.

OTHER INCOME (EXPENSE): Other income for the three months ended September 30,
2004 was $203,339 as compared to $511,949 for the three months ended September
30, 2003. The decrease of $308,610 was primarily due to a decrease in royalty
income. The Company received an additional royalty payment for the quarter ended
September 30, 2003 of approximately $410,000, which was based upon a review of
USS' records that determined that royalties were due for prior years. The review
showed that USS owed (and subsequently paid in the first quarter of fiscal 2004)
royalties due on a product that was not included in the original royalty
computation.

INCOME TAXES: The effective tax rate is 38.4% for the three months ended
September 30, 2004 as compared to an effective tax rate of 40.6% for the three
months ended September 30, 2003. The current effective income tax rate of 38.4%
was favorably impacted by a higher proportionate increase in Labcaire income,
which is under UK tax regulations and has a lower standard tax rate.

CRITICAL ACCOUNTING POLICIES:

General: Financial Reporting Release No. 60, which was released by the
Securities and Exchange Commission in December 2001, requires all companies to
include a discussion of critical accounting policies or methods used in the
preparation of the financial statements. Note 1 of the Notes to Consolidated
Financial Statements included in the Company's Annual Report on Form 10-K for
the year ended June 30, 2004 includes a summary of the Company's significant
accounting policies and methods used in the preparation of its financial
statements. The Company's discussion and analysis of its financial condition and
results of operations are based upon the Company's financial statements, which
have been prepared in accordance with accounting principles generally accepted
in the United


                                       13


                                  MISONIX, INC.
                      MANAGEMENT'S DISCUSSION AND ANALYSIS
          OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED)


States. The preparation of these financial statements requires the Company to
make estimates and judgments that affect the reported amounts of assets,
liabilities, revenues and expenses. On an on-going basis, management evaluates
its estimates and judgments, including those related to bad debts, inventories,
goodwill, property, plant and equipment and income taxes. Management bases its
estimates and judgments on historical experience and on various other factors
that are believed to be reasonable under the circumstances, the results of which
form the basis for making judgments about the carrying values of assets and
liabilities that are not readily apparent from other sources. Actual results may
differ from these estimates under different assumptions or conditions. The
Company considers certain accounting policies related to allowance for doubtful
accounts, inventories, property, plant and equipment, goodwill, income taxes and
stock-based compensation to be critical policies due to the estimation process
involved in each.

Allowance for Doubtful Accounts: The Company's policy is to review its
customers' financial condition prior to extending credit and, generally,
collateral is not required. The Company utilizes letters of credit on foreign or
export sales where appropriate.

Inventories: Inventories are stated at the lower of cost (first-in, first-out)
or market and consist of raw materials, work-in-process and finished goods.
Management evaluates the need to record adjustments for impairments of inventory
on a quarterly basis. The Company's policy is to assess the valuation of all
inventories, including raw materials, work-in-process and finished goods.

Property, Plant and Equipment: Property, plant and equipment are recorded at
cost. Depreciation of property and equipment is provided using the straight-line
method over estimated useful lives ranging from 1 to 5 years. Depreciation of
the Labcaire building is provided using the straight-line method over the
estimated useful life of 50 years. Leasehold improvements are amortized over the
life of the lease or the useful life of the related asset, whichever is shorter.
The Company's policy is to periodically evaluate the appropriateness of the
lives assigned to property, plant and equipment and to make adjustments if
necessary.

Goodwill: In July 2001, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 141 ("SFAS 141") and
SFAS 142 ("SFAS 142"), "Business Combinations" and "Goodwill and Other
Intangible Assets", respectively. SFAS 141 replaced Accounting Principles Board
("APB") Opinion 16 "Business Combinations" and requires the use of the purchase
method for all business combinations initiated after June 30, 2001. SFAS 142
requires goodwill and intangible assets with indefinite useful lives to no
longer be amortized, but instead be tested for impairment at least annually and
whenever events or circumstances occur that indicate goodwill might be impaired.
With the adoption of SFAS 142, as of July 1, 2001, the Company reassessed the
useful lives and residual values of all acquired intangible assets to make any
necessary amortization period adjustments. Based on that assessment, only
goodwill was determined to have an indefinite useful life and no adjustments
were made to the amortization period or residual values of other intangible
assets. SFAS 142 provided a six-month transitional period from the effective
date of adoption for the Company to perform an assessment of whether there is an
indication that goodwill is impaired. To the extent that an indication of
impairment exists, the Company must perform a second test to measure the amount
of impairment. The second test must be performed as soon as possible, but no
later than the end of the fiscal year. Any impairment measured as of the date of
adoption will be recognized as the cumulative effect of a change in accounting
principle. The Company performed the first test and determined that there is no
indication that the goodwill recorded is impaired and, therefore, the second
test was not required. The Company also completed its annual goodwill impairment
tests for fiscal 2004 in the fourth quarter with no impairment noted.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
          OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED)


Income Taxes: Income taxes are accounted for in accordance with SFAS No. 109,
"Accounting for Income Taxes". Under this method, deferred tax assets and
liabilities are recognized for the future tax consequences attributable to
differences between the financial statement carrying amounts of existing assets
and liabilities and their respective tax bases, operating loss and tax credit
carry forwards. Deferred tax assets and liabilities are measured using enacted
tax rates expected to apply to taxable income in the years in which those
temporary differences are expected to be recovered or settled. The effect on
deferred tax assets and liabilities of a change in tax rates is recognized in
income in the period that includes the enactment date.

Stock-Based Compensation: The Company accounts for its stock-based compensation
plans in accordance with APB Opinion No. 25, "Accounting for Stock Issued to
Employees" ("APB 25") and related interpretations. Under APB 25, because the
exercise price of the Company's employee stock options is generally set equal to
the market price of the underlying stock on the date of grant, no compensation
expense is recognized.

RECENT ACCOUNTING PRONOUNCEMENTS

In January 2003, the FASB issued FASB Interpretation 46 "Consolidation of
Variable Interest Entities, an Interpretation of ARB No. 51" ("FIN 46"). In
December 2003, the FASB modified FIN 46 to make certain technical corrections
and address certain implementation issues that had arisen. FIN 46 provides a new
framework for identifying a variable interest entity ("VIE") and determining
when a company should include the assets, liabilities, noncontrolling interests
and results of activities of a VIE in its consolidated financial statements.

In general, a VIE is a corporation, partnership, limited liability company,
trust, or any other legal structure used to conduct activities or hold assets
that either (1) has an insufficient amount of equity to carry out its principal
activities without additional subordinated financial support, (2) has a group of
equity owners that are unable to make significant decisions about its
activities, or (3) has a group of equity owners that do not have the obligation
to absorb losses or the right to receive returns generated by its operations.

FIN 46 requires a VIE to be consolidated if a party with an ownership,
contractual or other financial interest in the VIE (a variable interest holder)
is obligated to absorb a majority of the risk of loss from the VIE's activities,
is entitled to receive a majority of the VIE's residual returns (if no party
absorbs a majority of the VIE's losses), or both. A variable interest holder
that consolidates the VIE is called the primary beneficiary. Upon consolidation,
the primary beneficiary generally must initially record all of the VIE's assets,
liabilities and noncontrolling interests at fair value and subsequently account
for the VIE as if it were consolidated based on majority voting interest. FIN 46
also requires disclosures about VIEs that the variable interest holder is not
required to consolidate but in which it has a significant variable interest.

In connection with the adoption of FIN 46 during the third quarter of fiscal
2004, the Company consolidated Hearing Innovations in its March 31, 2004 balance
sheet as the entity was determined to be a VIE and the Company is its primary
beneficiary. The Company elected to record the adoption of FIN 46 as a
cumulative effect of an accounting change. Consolidating Hearing Innovations did
not have a material impact on the Company's consolidated results of operations
or financial condition. Prior periods were not restated. For additional
information on Hearing Innovations see Note 7 of the consolidated financial
statements.

On March 31, 2004, the FASB issued an Exposure Draft, "Share-Based Payment - An
Amendment of FASB Statements No. 123 and 95" (proposed "FAS 123R"), which is
currently is expected to be


                                       15


                                  MISONIX, INC.
                      MANAGEMENT'S DISCUSSION AND ANALYSIS
          OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED)


effective for public companies in periods beginning after June 15, 2005. We
would be required to implement the proposed standard no later than the quarter
that begins July 1, 2005. The cumulative effect of adoption, if any, applied on
a modified prospective basis, would be measured and recognized on July 1, 2005.
FASB 123R would eliminate the ability to account for share-based compensation
transactions using APB 25, and would instead require companies to recognize
compensation expense, using a fair-value based method, for costs related to
share-based payments including stock options and employee stock purchase plans.
The FASB expects to issue a final standard by December 31, 2004. The Company is
in the process of determining the impact of this statement on its consolidated
financial statements.

Forward Looking Statements: This report contains certain forward looking
statements within the meaning of Section 27A of the Securities Act and Section
21E of the Exchange Act, which are intended to be covered by the safe harbors
created thereby. Although the Company believes that the assumptions underlying
the forward looking statements contained herein are reasonable, any of the
assumptions could be inaccurate, and therefore, there can be no assurance that
the forward looking statements contained in this report will prove to be
accurate. Factors that could cause actual results to differ from the results
specifically discussed in the forward looking statements include, but are not
limited to, the absence of anticipated contracts, higher than historical costs
incurred in performance of contracts or in conducting other activities, product
mix in sales, results of joint ventures and investments in related entities,
future economic, competitive and market conditions, and the outcome of legal
proceedings as well as management business decisions.

LIQUIDITY AND CAPITAL RESOURCES:

Working capital at September 30, 2004 and June 30, 2004 was $17,610,555 and
$16,997,590, respectively. In the three months ended September 30, 2004, cash
used in operations totaled $1,174,296. The decrease in the cash balance is
predominately due to the increase in inventory to support future shipments and
payments of accounts payable and accrued expenses. In the three months ended
September 30, 2004, cash used in investing activities was $109,858, which
primarily consisted of the purchase of property, plant and equipment during the
regular course of business. In the three months ended September 30, 2004, cash
provided by financing activities was $272,571 primarily consisting of proceeds
from short-term borrowings and receipts from the exercise of employee stock
options offset by payments on capital lease obligations and long term debt.


REVOLVING CREDIT FACILITIES

Labcaire has a debt purchase agreement with Lloyds TSB Commercial Finance. The
amount of this facility is approximately $1,710,000 ((pound)950,000) and bears

$14,500,000. The terms provide for the repayment of the debt in full on its
maturity date. On September 30, 2004, the Company had $5,000,000 available on
this line of credit. The Company is in compliance with all such covenants.

HEARING INNOVATIONS, INC.

During fiscal 2005, the Company entered into a loan agreement whereby Hearing
Innovations is required to pay the Company $16,720. This note is due December
31, 2004. Hearing Innovations is currently negotiating with the Company to
extend the due dates of all its outstanding debt. The note bears interest at 8%
per annum. The note is secured by a lien on all of Hearing Innovations' right,
title and interest in accounts receivable, inventory, property, plant and
equipment and processes of specified products whether now existing or arising
after the date of this agreement. The loan agreement contains warrants to
acquire 16,720 shares of Hearing Innovations common stock, at the option of the
Company, at a cost of $.20 per share. These warrants, which are deemed nominal
in value, expire in December 2005. The current ability of companies such as
Hearing Innovations to access capital markets or incur third party debt is very
limited and is likely to remain so for the foreseeable future. In light of this
fact, Hearing Innovations suspended operations in April 2004.

In connection with the adoption of FIN 46, the Company consolidated Hearing
Innovations in its March 31, 2004 balance sheet as the entity was determined to
be a VIE and the Company is its primary beneficiary. The Company elected to
record the adoption of FIN 46 as a cumulative effect of an accounting change.
Consolidating Hearing Innovations did not have a material impact on the
Company's consolidated results of operations or financial condition.

On July 14, 2004, Hearing Innovations sent all shareholders and creditors a plan
for reorganization and disclosure statement. The Company committed to fund
Hearing Innovations up to $150,000 for the reorganization plan. Hearing
Innovations plans to file for relief under Chapter 11 of the U.S. Bankruptcy
Code in November 2004. If the petition is approved, the Company will own 100% of
the equity in Hearing Innovations.

OFF-BALANCE SHEET ARRANGEMENTS

The Company has no off-balance sheet arrangements that have or are reasonably
likely to have a current or future effect on the Company's financial condition,
changes in financial condition, revenues or expenses, results of operations,
liquidity, capital expenditures or capital resources that is material to the
Company.

OTHER

The Company believes that its existing capital resources will enable it to
maintain its current and planned operations for at least 18 months from the date
hereof due to the increase in cash flow from operations. The Company expects
future cash flow from operations to fund all the ongoing cash flow needs.

In the opinion of management, inflation has not had a material effect on the
operations of the Company.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

Market Risk:

The principal market risks (i.e., the risk of loss arising from adverse changes
in market rates and prices) to which the Company is exposed are interest rates
on short-term investments and foreign exchange rates, which generate translation
gains and losses due to the English Pound to U.S. Dollar conversion of Labcaire.

Foreign Exchange Rates:

Approximately 25% of the Company's revenues in the period ended September 30,
2004 were received in English Pounds currency. To the extent that the Company's
revenues are generated in English Pounds, its operating results are translated
for reporting purposes into U.S. Dollars using rates of 1.79 and 1.61 for the
three months ended September 30, 2004 and 2003, respectively. A strengthening of
the English Pound, in relation to the U.S. Dollar, will have the effect of
increasing its reported revenues and profits, while a weakening of the English
Pound will have the opposite effect. Since the Company's operations in England
generally sets prices and bids for contracts in English Pounds, a strengthening
of the English Pound, while increasing the value of its UK assets, might place
the Company at a pricing disadvantage in bidding for work from manufacturers
based overseas. The Company collects its receivables in the currency the
subsidiary resides in. The Company has not engaged in foreign currency hedging
transactions, which include forward exchange agreements.

Item 4. Controls and Procedures.

Our disclosure controls and procedures (as defined in Rules 13a-15(e) and
15d-15(e) under the Securities Exchange Act of 1934, as amended (the "Exchange
Act")) are designed to ensure that information required to be disclosed in the
reports that we file or submit under the Exchange Act is recorded, processed,
summarized and reported within the time periods specified in the rules and forms
of the Securities and Exchange Commission. The Company carried out an
evaluation, under the supervision and with the participation of the Company's
management, including the Company's Chief Executive Officer and Chief Financial
Officer, of the effectiveness of the design and operation of the Company's
disclosure controls and procedures as of September 30, 2004 and, based on their
evaluation, the Chief Executive Officer and Chief Financial Officer concluded
that the Company's disclosure controls and procedures are effective.

There has been no change in the Company's internal control over financial
reporting (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act) that
occurred during the first quarter of fiscal 2005 that has materially affected,
or is reasonable likely to materially affect, the Company's internal control
over financial reporting.
