              Notes to Consolidated Condensed Financial Statements
                                December 31, 2001
                                   (Unaudited)

NOTE 1:  BASIS OF PRESENTATION
The accompanying financial statements for the interim periods are unaudited and
reflect all adjustments (consisting only of normal recurring adjustments) which
are, in the opinion of management, necessary for a fair presentation of the
financial position and operating results for the interim periods. These
financial statements should be read in conjunction with the financial statements
and notes thereto, together with the management's discussion and analysis,
contained on Form 10-KSB for the year ended June 30, 2001. The results of
operations for the three and six months ended December 31, 2001 are not
necessarily indicative of the results for the entire fiscal year ending June 30,
2002.

The accompanying financial statements reflect the consolidated operations of
Sonics & Materials, Inc. and its wholly-owned subsidiary, Tooltex, Inc. through
the date of the sale of 90% of the common stock of Tooltex, Inc. on August 21,
2001. All significant intercompany accounts and transactions have been
eliminated in consolidation.

NOTE 2:  SALE OF TOOLTEX, INC. STOCK
On August 21, 2001, the Company sold a 90% interest in the stock of Tooltex to
PK Spur Co. (PK), an Ohio corporation owned by the president of Tooltex, and his
wife. In consideration, PK issued a $125,000 promissory note, payable in 23
installments of $2,000 including interest at 7% per annum commencing in October
2001, with a final balloon payment of outstanding principal and accrued
interest. The note is guaranteed by the president of Tooltex, and is secured by
a security interest in certain Tooltex assets. In conjunction with the sale, the
Company and Tooltex entered into a representation and distribution agreement
pursuant to which Tooltex will sell and distribute the Company's products.

The Company changed the accounting for its investment in Tooltex from the
consolidation to the cost method, effective on the date of sale. Tooltex
reported sales of approximately $90,000 and a net loss of approximately $25,000
in the quarter ended September 30, 2001.

NOTE 3:  SALE OF COMPANY FACILITY
On August 31, 2001, the Company sold to Acme Realty (Acme), a New York general
partnership, its manufacturing facility located in Newtown, Connecticut for
$4,000,000 in cash, less expenses of $244,000. The Company used the proceeds to
pay outstanding Industrial Revenue Bond principal and accrued interest totaling
$3,289,000, and to increase working capital. In conjunction with the sale, the
Company entered into a triple net lease with Acme for an initial term of ten
years plus two five-year renewal options. The Company recorded a deferred gain
on the sale of $337,000, which will be amortized over the lease term.

Following is a schedule of minimum lease payments due under the operating lease
for the property:

NOTE 4:  NET INCOME PER SHARE
Net income per share is based on the weighted average number of common and
common equivalent shares outstanding during the period, calculated using the
treasury stock method. Stock options of which approximately 346,000 are
currently outstanding, are antidilutive for all periods and accordingly, are not
included in the per share computations.

NOTE 5: INCOME TAXES
The effective tax rate for the six months ended December 31, 2001 was 10.7% due
to the utilization of regular net operating loss carryovers of $168,000 and
federal tax credits of $6,000. These tax benefits had previously been subject to
deferred tax valuation allowances. The Company also has available capital loss
carryovers to offset the entire capital gain income recognized on the sale of
real estate in the first quarter of 2001. The gain is being amortized for
financial reporting purposes over the term of the related lease, but will be
recognized in full as of the transaction date for income tax purposes.

Future taxable income in fiscal 2002 will be subject to an effective tax rate in
the range of 40%-45%.

The Company did not provide for the tax benefit of net operating losses incurred
during the comparable 2000 period due to uncertainty as to their realization.

will be achieved.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS

The following information should be read in conjunction with the unaudited
financial statements included herein, see Item 1, and the financial information
contained in the Company's latest annual report on Form 10-KSB for the year
ended June 30, 2001.

RESULTS OF OPERATIONS

THREE MONTHS ENDED DECEMBER 31, 2001 COMPARED TO THE THREE MONTHS ENDED DECEMBER
31, 2000.

NET SALES. Net sales for the quarter ended December 31, 2001 decreased $330,000
or 11.3% compared with the same quarter in fiscal year 2001. This decrease
resulted from the elimination of Tooltex, Inc. revenues, which was sold in
August 2001. The decrease in revenues was partially offset by the increase in
plastics assembly product sales.

COST OF SALES AND GROSS PROFITS. Cost of sales decreased from 65.1% in the three
months ended December 31, 2000 to 61.0% for the three months ended December 31,
2001. In spite of the decline in sales, the improvement in cost of sales enabled
gross profits to remain essentially the same, amounting to $1,013,000 in the
current quarter and $1,023,000 in the comparable quarter of the prior fiscal
year. The improvement in gross profit margins resulted from a combination of a
more favorable product mix and the full realization of savings made as a result
of cost cutting measures taken in the second and third quarters of fiscal year
2001.

SELLING EXPENSES. Selling expenses for the second quarter of fiscal 2002
decreased $295,000 or 38.9% compared with the same quarter in fiscal 2001. As a
percentage of net sales, selling expense decreased from 25.9% to 17.8% over the
same period. The improvement in the level of selling expenses was achieved both
on an absolute basis and as a percentage of sales. The principal areas of
selling expense reduction were in payroll, advertising and promotional costs. In
addition, selling expenses decreased as a result of the sale of Tooltex, Inc.

GENERAL AND ADMINISTRATIVE EXPENSES. General and administrative expenses for the
second quarter of fiscal 2002 decreased $120,000 compared with the second
quarter of the prior fiscal year. The principal reason for the decrease in these
expenses is due to the sale of Tooltex, Inc.

INTEREST EXPENSE. Interest expense decreased by $93,000 compared with the same
period in fiscal year 2001. The savings in interest resulted from the
elimination of Industrial Revenue Bond indebtedness relating to the sale of real
estate in August 2001, as well as a significant decline in interest rates.

INCOME TAXES. The effective tax rate for the three months ended December 31,
2001 was 12.7% due to the utilization of regular net operating loss carryovers
of $120,000 and federal tax credits of $6,000. These tax benefits had previously
been subject to deferred tax valuation allowances. The Company also has
available capital loss carryovers to offset the entire capital gain income
recognized on the sale of real estate in the

                                        8
<PAGE>

first quarter of 2001. The gain is being amortized for financial reporting
purposes over the term of the related lease, but will be recognized in full as
of the transaction date for income tax purposes.

Future taxable income in fiscal 2002 will be subject to an effective tax rate in
the range of 40%-45%.

The Company did not provide for the tax benefit of net operating losses incurred
during the comparable 2000 period due to uncertainty as to their realization.

SIX MONTHS ENDED DECEMBER 31, 2001 COMPARED TO THE SIX MONTHS ENDED DECEMBER 31,
2000.

NET SALES. Net sales for six months ended December 31, 2001 decreased $1,005,000
compared to the prior comparable period. The majority of the decline resulted
from the elimination of Tooltex, Inc. revenues as a result of the sale of that
subsidiary in August 2001.

COST OF SALES AND GROSS PROFITS. Cost of sales decreased from 63.3% for the six
months ended December 31, 2000 to 61.3% for the six months ended December 31,
2001. Accordingly, gross margins improved from 36.7% to 38.7%. A decline in the
plastics product line gross margin caused by less favorable product mix was more
than offset by the elimination of the lower-margin Tooltex product line as well
as savings from the full realization of cost cutting measures begun in the
second quarter of fiscal year 2001.

SELLING EXPENSES. Selling expenses decreased $592,000 compared with the same
period of the prior year. This decrease took place in the areas of payroll,
commissions, advertising and promotional costs. In addition, selling expenses
decreased as a result of the sale of Tooltex, Inc.

GENERAL AND ADMINISTRATIVE EXPENSES. General and administrative expenses for the
six months ended December 31, 2001 decreased $176,000 compared with the
comparable period of the prior fiscal year. The principal reason for this
decline was the elimination of these costs caused by the sale of Tooltex, Inc.

INTEREST EXPENSE. Interest expense decreased $120,000 in the six months ended
December 31, 2001. The savings in interest resulted from the elimination of
Industrial Revenue Bond indebtedness relating to the sale of real estate in
August 2001 and a significant decline in interest rates.

INCOME TAXES. The effective tax rate for the six months ended December 31, 2001
was 10.7% due to the utilization of regular net operating loss carryovers of
$168,000 and federal tax credits of $6,000. These tax benefits had previously
been subject to deferred tax valuation allowances. The Company also has
available capital loss carryovers to offset the entire capital gain income
recognized on the sale of real estate in the first quarter of 2001. The gain is
being amortized for financial reporting purposes over the term of the related
lease, but will be recognized in full as of the transaction date for income tax
purposes.

Future taxable income in fiscal 2002 will be subject to an effective tax rate in
the range of 40%-45%.

The Company did not provide for the tax benefit of net operating losses incurred
during the comparable 2000 period due to uncertainty as to their realization.

LIQUIDITY AND CAPITAL RESOURCES

The Company's balance sheet strengthened steadily in the last two quarters.
Contributing to the improved balance sheet is the Company's return to
profitability, in part, due to the cost cutting measures taken beginning in the
second quarter of fiscal year 2001, the sale of the Company's manufacturing
facility in Newtown, CT, and the sale of Tooltex, Inc.

Working capital increased by $928,000 June 30, 2001 and December 31, 2001. Cash
amounted to $1,179,000 at December 31, 2001, an increase of $359,000 over the
fiscal year end close. The note payable to the Company's bank was reduced by
$700,000 during this same period of time.

The Company's debt/equity ratio, during the six months ended December 31, 2001
also improved, declining from 1.2 times to 0.4 times.

                                        9
<PAGE>

The Company's principal outside source of working capital is a $1,500,000 bank
credit facility (the "Line of Credit"). The Line of Credit bears interest at the
bank's base lending rate (4.75% at December 31, 2001). Advances under the Line
of Credit are at the bank's sole discretion. The entire principal balance of the
Line of Credit, which at December 31, 2001 was $490,000, is due and payable upon
the demand of the bank. The borrowings under the Line of Credit may be prepaid
in whole or in part, without premium or penalty, at any time. Indebtedness under
the Company's Line of Credit and the term loan are secured by substantially all
of the assets of the Company. The credit agreement also subjects the Company to
various covenants, including restrictions on future borrowings and encumbrances,
and the maintenance of minimum tangible net worth, leverage and fixed charge
coverage ratios, as defined. The Company met its covenants as of December 31,
2001.

IMPACT OF INFLATION

The Company does not believe that inflation significantly affected its results
of operations for the current fiscal quarter.

MARKET RISK

The Company does not hold or trade derivative instruments. Financial instruments
subject to changes in interest rates consist primarily of floating rate debt.
Due to the repayment in August 2001 of its Industrial Development Bonds, the
Company's exposure to interest rate fluctuations is not material. The Company's
transactions are generally conducted and its accounts are denominated in U.S.
dollars. Consequently, exposure to foreign risk is not significant.

RECENTLY ISSUED PRONOUNCEMENTS

In June 2001, the FASB issued SFAS No. 141, Business Combinations, which
addressed the initial recognition and measurement of goodwill and other
intangible assets acquired in a business combination. SFAS No. 141 requires the
purchase method of accounting to be used for business combinations initiated
after June 30, 2001 and eliminates the pooling of interest method. The adoption
of this statement is not expected to have a material impact on the Company's
financial position or results of operations.

In June 2001, the FASB issued SFAS No. 142, Goodwill and Other Intangible
Assets, which addressed the recognition and measurement of goodwill and other
intangible assets subsequent to their acquisition. SFAS No. 142 also addressed
the initial recognition and measurement of intangible assets acquired outside of
a business combination whether acquired individually or with a group of other
assets. SFAS No. 142 provides that intangible assets with finite useful lives be
amortized and that intangible assets with indefinite lives and goodwill will not
be amortized, but will rather be tested at least annually for impairment.
Although SFAS No. 142 is not required to be adopted by the Company until fiscal
2003, its provisions must be applied to goodwill and other intangible assets
acquired after June 30, 2001. As of December 31, 2001, the Company does not have
any goodwill or other intangible assets relating to business combinations that
were accounted for under APB Opinion No. 16. Accordingly, the adoption of SFAS
No. 142 is not expected to have a material impact on the Company's financial
position or results of operations.
