    and cash flows for the six months ended February 24, 2001 and February 26,
    2000.  Certain prior year amounts have been reclassified to conform to the

5.      Change in Method of Accounting for Inventories
        -----------------------------------------------

Effective August 27, 2000, the Company changed its method of accounting for its
domestic inventories from the last-in, first-out (LIFO) method to the first-in,
first-out (FIFO) method. Management believes that the accounting change is
preferable in the circumstances because the accounting change provides a better
matching of costs and revenues in periods when the cost of goods and services
are declining. In accordance with accounting principles generally accepted in
the United States of America, the financial statements of prior periods have
been restated to apply the new method retroactively. Accordingly, retained
earnings at August 26, 2000 on the accompanying balance sheet has been adjusted
for the effect (net of income taxes) of applying retroactively the new method of
accounting.

The effect of the accounting change on income for the three months and six
months ended February 24, 2001 and February 26, 2000 is shown below:

6.  Distribution Agreement Termination
    ----------------------------------

During the second quarter of fiscal 2001, the Company recorded a one-time charge
of $8.2 million related to the early termination of a distribution agreement for
the Microelectronics Group with its affiliate, Metron Technology N.V. (Metron).
Pursuant to the termination agreement, the Company will assume direct sales
responsibility for Microelectronics Group product sales in Europe and Asia, and
agreed to transfer to Metron 1.125 million shares of Metron stock and to make
cash payments totaling $1.75 million over a 15-month period. Entegris will also
buy back certain microelectronics product inventory, to be determined at a later
date, from Metron, which will be accounted for if and when such inventory is
transferred from Metron. The Company and Metron also executed a new distribution
agreement for Entegris' Fluid Handling Group products, which now runs through
August 31, 2005.

Net sales Net sales increased 25% to $105.7 million in the second quarter of
fiscal 2001, compared to $84.8 million in the first quarter of fiscal 2000. The
improvement reflects the continuation of the sustained recovery in the
semiconductor industry that began in the second half of fiscal 1999. Revenue
gains were recorded in North America, Japan and Europe, while revenues in the
Asia Pacific region were flat. International sales accounted for approximately
49% of net sales, essentially unchanged from fiscal 2000 and first quarter
fiscal 2001 levels. Sales of fluid handling products, which made up 34 percent
of total sales for the quarter, increased 67 percent, while microelectronics
product sales, 66% of total sales, grew 18%.

Net sales for the first six months of fiscal 2001 were $208.4 million, up 33%
from $156.7 million in the comparable year-ago period. Revenue gains were
recorded in all geographic regions, most notably in Japan. Fluid handling
product and microelectronics sales increased 75% and 24%, respectively, compared
to first six months of fiscal 2000.

Incoming order rates began to decline late in the quarter, particularly for
fluid handling products, which are dependent on capital spending levels in the
semiconductor industry. There was also some weakness in orders for
microelectronics products as manufacturing utilization of wafer manufacturers
and semiconductor manufacturers started to decline. A clear trend has not yet
been established, but the company is preparing for the possibility of a
significant industry slowdown.

Currently, management expects that sales for the third quarter of fiscal 2001
will decrease by about 15-20% from the sales levels experienced in the second
quarter of fiscal 2001.

                                       8


Gross profit Gross profit in the second quarter of fiscal 2001 increased 40% to
$53.6 million, compared to $38.1 million reported in the second quarter of
fiscal 2000. For the first six months of fiscal 2001, gross profit was $106.2
million, up 52% from $69.8 million recorded in the first six months of fiscal
2000. As a percentage of net sales, gross margins for the second quarter and
first six months of the fiscal year were 50.7% and 50.9%, respectively, compared
to 45.0% and 44.6%, respectively, in the comparable periods a year ago.

The gross profit and gross margin improvements in fiscal 2001 reflected improved
utilization of our production capacity associated with the higher sales levels
noted above and the successful management of manufacturing costs. Gross profit
and gross margin gains were reported by both domestic and international
operations. Partly offsetting the gross profit and gross margin improvements
were asset impairment charges of $2.7 million and $3.4 million recorded in the
second quarter and first six months of fiscal 2001, respectively, mainly for
asset write-offs of molds that were determined to have no future use. As noted
in Note 5 to the accompanying consolidated financial statements, the Company
changed its method of accounting for inventories from LIFO to FIFO in the first
quarter of fiscal 2001.

As discussed above, management expects sales levels to decline in the third
quarter. The corresponding reduction in our factory utilization would result in
lower gross profits with an expected gross margin in mid-40% range.

Selling, general and administrative expenses Selling, general and administrative
(SG&A) expenses increased 6% to $19.7 million in the second quarter of fiscal
2001 from $18.6 million in the second quarter of fiscal 2000. SG&A expenses grew
22% to $41.0 million in the first six months of fiscal 2001 compared to $33.7
million in the first six months a year earlier. The increases reflect higher
commissions, incentive compensation, charitable contributions, and personnel and
information systems costs. On a year-to-date basis, SG&A costs, as a percent of
net sales, decreased slightly to 19.7% from 21.5% a year ago.

Distribution termination agreement During the second quarter of fiscal 2001, the
Company recorded a one-time charge of $8.2 million related to the early
termination of a distribution agreement for the Microelectronics Group with its
affiliate Metron Technology N.V. (Metron). Pursuant to the termination
agreement, the Company will assume direct sales responsibility for
Microelectronics Group product sales in Europe and Asia, and agreed to transfer
to Metron 1.125 million shares of Metron stock and to make cash payments
totaling $1.75 million over a 15-month period. Entegris will also buy back
certain microelectronics product inventory, to be determined at a later date,
from Metron, which will be accounted for if and when such inventory is
transferred from Metron. The Company and Metron also executed a new distribution
agreement for Entegris' Fluid Handling Group products, which now runs through
August 31, 2005.

Engineering, research and development expenses Engineering, research and
development (ER&D) expenses increased 11% to $4.0 million, or 3.8% of net sales,
in the second quarter of fiscal 2001as compared to $3.6 million, or 4.3% of net
sales, for the same period in fiscal 2000. ER&D expenses increased 6% to $7.6
million, or 3.6% of net sales, in the first six months of fiscal 2001 as
compared to $7.1 million, or 4.6% of net sales, a year-ago period. A major
element of ER&D expenses relates to the continued development of next generation
300mm products.

Interest (income) expense Net interest income was $1.4 million in the second
quarter of fiscal 2001 compared to net interest expense of $0.9 million in the
year-ago period. Net interest income was $2.9 million in the first half of
fiscal 2001 compared to net interest expense of $2.0 million for the same period
in fiscal 2000. The variance reflected the elimination of domestic bank
borrowings and capital lease obligations, as well as the short-term investment
of sizable available cash balances, made possible by the receipt of net proceeds
of $99.0 million from the Company's initial public offering in the fourth
quarter of fiscal 2000, $42 million of which was used to retire long-term debt
and capital lease obligations.

                                       9


Other expense (income) Other expense was $0.9 million in the second quarter of
fiscal 2001 as compared to other income of $0.2 million a year ago. Other
expense was $1.0 million in the first half of fiscal 2001 compared to other
income of $6.3 million in the first half of fiscal 2000.  The main factor
underlying the year-to-year variance is the first quarter fiscal 2000 $5.5
million pre-tax gain recognized on the sale of approximately 612,000 common
shares of the Company's investment in Metron as part of Metron's initial public
offering in November 1999. The recording of translation losses in the fiscal
2001 periods compared to translation gains in fiscal 2000 also contributed to
the change.

Income tax expense Income tax expense of $19.5 million was significantly higher
in the first half of fiscal 2001 compared to $11.1 million in income tax expense
reported a year earlier, primarily reflecting higher pre-tax income. The
effective tax rate thus far in fiscal 2001 is 38.0% compared to 33.5% in fiscal
2000, and primarily reflects the higher income levels earned by the Company.

Equity in net income of affiliates Equity in the net income of affiliates was
$0.8 million in the second quarter of fiscal 2001 compared to $0.3 million in
the second quarter a year earlier, while equity in the net income of affiliates
was $1.5 million in the first half of fiscal 2001 compared to $0.6 million for
the same period a year ago. These improvements primarily reflect the operating
results of Metron, which also benefited from the favorable industry conditions
affecting our results.

During March 2001, we surrendered ownership of 1.125 million shares of our
investment in Metron in connection with the charge described above under the
caption "Distribution Agreement Termination". As a result, our percentage
ownership in Metron will be approximately 12%. Accordingly, the Company will
discontinue application of the equity method to account for its investment in
Metron. Instead, the Company's remaining investment will be accounted for as an
"available-for-sale security" under the provisions of Statement of Financial
Accounting Standards (SFAS) No. 115 - Accounting for Certain Investments in Debt
and Equity Securities.

Minority interest For the six months ended February 24, 2001, minority interest
in subsidiaries' net income line nearly quadrupled over a year ago. This
increased charge to earnings reflects the improved financial performance at our
51% owned Japanese subsidiaries.

Net income Net income increased 33% to $13.8 million in the second quarter of
fiscal 2001, compared to net income of $10.3 million in the year-ago period. Net
income applicable to nonredeemable common shareholders was $13.8 million, or
$0.19 per diluted share, for the quarter, compared to a net loss applicable to
nonredeemable common shareholders of $22.5 million, or $0.60 per share diluted,
in the second quarter of fiscal 2000. Excluding the effect of the market value
adjustment related to redeemable common stock, pro forma earnings per diluted
share were $0.16 per share in the second quarter of fiscal 2000.

Net income increased to $31.9 million in the first half of fiscal 2001, compared
to net income of $22.4 million in the comparable year-ago period. Net income
applicable to nonredeemable common shareholders was $31.9 million, or $0.44 per
diluted share, in the half quarter of fiscal 2001. After the market value
adjustment related to redeemable common stock, the net loss applicable to
nonredeemable common shareholders was $43.2 million, or $1.16 per share diluted,
in the first half quarter of fiscal 2000. Excluding the effect of the market
value adjustment related to redeemable common stock, pro forma earnings per
diluted share were $0.35 per share in the first half of fiscal 2000.

Liquidity and Capital Resources

Operating activities Cash flow provided by operating activities totaled $26.1
million in the first half of fiscal 2001. Net income and noncash charges, such
as depreciation and amortization, totaled nearly $45 million, accounting for the
strong cash flow generated by operations, which was partly offset by higher
working capital requirements, principally related to higher accounts receivable
($11.6 million) and inventories ($9.6 million). Working capital at February 24,
2001 stood at $193.5 million, including $119.6 million in cash and cash
equivalents.

                                       10


The growth in accounts receivables primarily reflected the increase in net
sales. Inventories rose because the Company increased the safety stock of
certain critical resins where the supplier had indicated possible delivery
issues and built up the supply of fluid handling components used in the
production of fluid handling products because of strong customer demand. The
company has started to decrease its safety stock inventories and adjusted its
raw material requirements based on projected business levels.  Accordingly,
inventory levels are expected to moderate or decline in the upcoming quarter
based on these actions.

Investing activities Cash flow used in investing activities totaled $10.0
million in the first half of fiscal 2001. Acquisition of property and equipment
totaled $11.6 million, primarily related to increasing our manufacturing
capabilities for 300mm products, tooling for new products, and investments in
our e-business initiatives. The Company expects capital expenditures of
approximately $30 million during fiscal 2001, consisting mainly of spending on
manufacturing equipment and information systems.

In the first quarter of fiscal 2000, we received $7.4 million from the sale of
612,000 shares of our investment in Metron Technology N.V. (Metron).

Financing activities Cash provided by financing activities totaled $0.8 million
during the first half of fiscal 2001. Short-term borrowings by international
operations rose by $1.2 million, while scheduled payments of $1.0 million were
made on outstanding borrowings. We repurchased common shares for $0.7 million in
the first half of fiscal 2001. These shares were acquired in connection with the
redemption of common stock from the Company's Employee Stock Ownership Plan and
the repurchase of 55,000 common shares as part of the 500,000 shares authorized
for repurchase by the Company's Board of Directors in the first quarter of
fiscal 2001.

At February 24, 2001, the Company's shareholders' equity stood at $297.7
million. Book value per share was $4.34, up from $3.91 per share at the end of
fiscal 2000. Net earnings accounted for the increase.

As of February 24, 2001, our sources of available funds comprised $119.6 million
in cash and cash equivalents, and various credit facilities. We have unsecured
revolving commitments with two commercial banks with aggregate borrowing
capacity of $30.0 million, with no borrowings outstanding at February 24, 2001.
We also have lines of credit, equivalent to an aggregate of approximately $12
million with six international banks, which provide for borrowings of German
deutsche marks, Malaysian ringgits and Japanese yen for our overseas
subsidiaries. Borrowings outstanding on these lines of credit were $9.6 million
at February 24, 2001.

The Company believes that its cash and cash equivalents, cash flow from
operations and available credit facilities will be sufficient to meet our
working capital and investment requirements for the next twelve months. However,
future growth, including potential acquisitions, may require additional funding,
and from time to time we may need to raise capital through additional equity or
debt financing.

Subsequent Event During the quarter, the Company agreed to acquire the fluid
handling component product line of a Japanese company for $10.4 million,
including an estimated $8.0 million to be recorded as goodwill. The purchase was
consummated in March 2001 and will be accounted for by the purchase method.
Accordingly, the Company's consolidated financial statements will include the
net assets and results of operations from the date of acquisition.

Cautionary Statements Certain information in this report does not relate to
historical financial information and may be deemed to constitute "forward-
looking statements" within the meaning of the Private Securities Litigation
Reform Act of 1995. These statements may include forward-looking statements
which reflect the Company's current views with respect to future events and
financial performance.  The words "believe," "expect," "anticipate," "intends,"
"estimate," "forecast," "project," "should" and similar expressions are intended
to identify "forward-looking statements" within the meaning of the Private
Securities Litigation Reform Act of 1995. Such statements are subject to certain
risks and uncertainties that could cause the company's actual results in the
future to differ materially from its historical results and those presently
anticipated or projected.

                                       11


Among these risks and uncertainties are general economic conditions, cyclical
nature of the semiconductor industry, risks associated with the acceptance of
new products and the successful transition to a direct sales model for
Microelectronic Group products. Other factors that could cause the company's
results to differ materially from those contained in its forward looking
statements are included in the Form 10K filed in November 2000 and other
documents filed by the company with the Securities and Exchange Commission.

Item 3:  Quantitative and Qualitative Disclosures About Market Risk
- -------------------------------------------------------------------

Our principal market risks are sensitivities to interest rates and foreign
currency exchange rates. Our exposure to interest rate fluctuations is not
significant. Most of our outstanding debt at February 24, 2001 carried fixed
rates of interest. Most of our short-term investments are debt instruments that
mature in three months or less.

We use derivative financial instruments to manage foreign currency exchange rate
risk associated with the sale of products from the United States when such sales
are denominated in currencies other than the U.S. dollar. The cash flows and
earnings of our foreign-based operations are also subject to fluctuations in
foreign exchange rates. A hypothetical 10% change in certain foreign currency
exchange rates would increase or decrease our net income by approximately $2
million.

Our cash flows and earnings are also subject to fluctuations in foreign exchange
rates due to investments in foreign-based affiliates. Investments in affiliates
includes our interest in Metron. Metron attempts to limit its exposure to
changing foreign currency exchange rates through operational and financial
market actions. Products are sold in a number of countries throughout the world
resulting in a diverse portfolio of transactions denominated in foreign
currencies. Metron manages certain short-term foreign currency exposures by the
purchase of forward contracts to offset the earnings and cash flow impact of
foreign currency denominated receivables and payables.

Our investment in Metron is accounted for by the equity method of accounting and
has a carrying value on the balance sheet of approximately $15.3 million. The
fair value of Metron is subject to stock market fluctuations. Based on the
closing stock price of Metron at February 24, 2001, the fair value of our
investment in Metron was approximately $14.8 million. As described above, we
surrendered ownership of 1.125 million shares of Metron in March 2001 in
connection with the charge described above under the caption "Distribution
Agreement Termination". As a result, our percentage ownership in Metron will
decrease to approximately 12%. Accordingly, the Company will discontinue
application of the equity method to account for its investment in Metron, with
the Company's remaining investment to be accounted for as an "available-for-sale
security" under the provisions of Statement of Financial Accounting Standards
(SFAS) No. 115.
