                             (dollars in thousands)

     The Company pays a commission to SpeedFam Co., Ltd. on sales of equipment
     produced by the Company in the U. S. and exported to Pacific Rim customers
     through SpeedFam Co., Ltd. As of August 31, 1997 the Company had accrued
     $2.3 million of commission expense to SpeedFam Co., Ltd.

(4)  LONG-TERM DEBT

     On August 29, 1997, the Company successfully negotiated a new unsecured
     credit facility with its U.S bank group. The new credit agreement provides
     for a revolving loan facility in the amount of $60 million with a term of
     three years. Should the loan be utilized, principal will be repaid at the
     end of the loan term. Interest will accrue and be paid monthly on the
     outstanding balance based on a 90 day LIBOR rate plus 25 to 100 basis
     points. The Company must meet certain financial objectives each year as
     defined in the credit agreement. At August 31, 1997, no amounts were
     outstanding on this loan facility.

(5)  OFFERING OF COMMON STOCK

     On September 17, 1997, the Company filed a registration statement on Form
     S-3 with the Securities and Exchange Commission reflecting a registration
     of 2,170,000 shares of common stock, 2,000,000 of which will be offered by
     the Company.

(6)  DERIVATIVE FINANCIAL INSTRUMENTS

     The Company uses derivative financial instruments to offset exposure to
     market risks arising from changes in foreign exchange rates. Derivative
     financial instruments currently utilized by the Company primarily include
     foreign currency forward contracts. The Company evaluates and monitors
     consolidated net exposures by currency and maturity, and external
     derivative financial instruments correlate with that net exposure in all
     material respects. Gains or losses related to hedges of firm commitments
     are deferred and included in the basis of the transaction when it is
     completed. Gains or losses on unhedged foreign currency transactions are
     included in income as part of cost of sales.

      Net Sales. The Company's net sales for the three months ended August 31,
1997 were $51.9 million, an increase of 36.4% over net sales of $38.1 million
for the corresponding period in the prior year. Sales of equipment, parts and
expendables increased to $43.8 million or 84.4% of net sales in the first
quarter of fiscal 1998, up from $31.2 million or 82.0% of net sales in the same
period of fiscal 1997. The growth in this segment was attributable to higher
sales of the Company's CMP systems to the semiconductor industry. Sales of CMP
systems generated $30.7 million, or 59.1% of net sales, nearly double the $16.3
million, or 42.8% of net sales, reported a year earlier. The growth in net sales
was also attributable to an increase in sales of slurries. Sales of slurries
increased 18.7% to $8.1 million or 15.6% of net sales in the first quarter of
fiscal 1998 from $6.8 million or 18.0% in the comparable period of fiscal 1997.

      Sales to the thin film memory disk media market accounted for $15.6
million, or 30.0% of net sales, compared with $15.5 million, or 40.9%, for the
first quarter of fiscal 1997. Although overall sales to this market were flat
with the prior year, equipment sales declined due to general over capacity in
the memory disk market and increased competition, which the Company expects to
continue for at least the next several quarters.

      Commissions from Affiliate. Commissions from affiliate increased to $1.9
million during the first quarter of fiscal 1998 from $1.7 million in the
corresponding period of fiscal 1997.

      Gross Margin. Gross margin increased to $23.0 million or 42.7% of total
revenue for the three months ended August 31, 1997 from $13.9 million or 35.1%
of total revenue for the three months ended August 31, 1996. The increase was
due to the continued shift in the revenue mix to higher margin CMP systems.

      Research, Development and Engineering. Research, development and
engineering expenses were $6.8 million or 12.6% of total revenue in the first
quarter of fiscal 1998 up from $3.8 million or 9.5% of total revenue in the
first quarter of fiscal 1997. This increase reflected the Company's significant
investment in dry-in/dry-out and end-point detection capabilities for its CMP
systems; upgrading a key product in the memory disk polishing market; and
various process technologies for the semiconductor device, thin film memory disk
media and silicon wafer markets.

      Selling, General and Administrative. Selling, general and administrative
expenses were $9.4 million, or 17.4% of total revenue, compared with $6.8
million, or 17.1%, a year ago. The percentage increase was due primarily to
higher commissions paid to the Far East Joint Venture for sales of CMP systems
manufactured in the United States, and continued investments in the Company's
sales, support and administrative infrastructure.

      Other Income (Expense). Other income increased to $759,000 in the first
quarter of fiscal 1998 from $445,000 of other expense in the comparable period
of fiscal 1997. Other income consisted almost entirely of interest income in the
first quarter of fiscal 1998.

      Equity in Net Earnings of Affiliates. The Company's equity in the net
earnings of its joint ventures was $729,000 for the first quarter, down from
$2.2 million a year ago, as a result of decreased net earnings of the Far East
Joint Venture. The Far East Joint Venture recently adopted an aggressive pricing
strategy designed to gain market share for its new automated disk polishing
systems. Although the Far East Joint Venture expects this gross margin pressure
to continue to negatively impact the Far East Joint Venture's earnings for at
least the near term, the Far East Joint Venture believes that this pricing
strategy represents an important strategic investment.

LIQUIDITY AND CAPITAL RESOURCES

      For the three months ended August 31, 1997, $201,000 in cash was used in
operating activities. Cash provided by net earnings and increases in accounts
payable and due to affiliates was offset by increases in accounts receivable and
inventories.

      On August 29, 1997, the Company successfully negotiated a new unsecured
credit facility with its U.S bank group which replaced the $22.5 million credit
facility and a $14 million term loan commitment. The new credit agreement
provides for a revolving loan facility in the amount of $60 million with a term
of three years. At August 31, 1997, no amounts were outstanding on this loan
facility.

      On September 17, 1997, the Company filed a registration statement on Form
S-3 with the Securities and Exchange Commission reflecting a registration of
2,170,000 shares of common stock, 2,000,000 of which will be offered by the
Company.

      The Company currently anticipates capital expenditures of approximately
$30.5 million for fiscal 1998. The Company believes that cash generated from
operations, together with the anticipated proceeds from the offering described
above and the revolving loan facilities will be sufficient to meet the Company's
capital requirements during at least the next 12 months.

      Statement of Financial Accounting Standards ("SFAS") No. 128 , "Earnings
per Share" is effective for financial statements issued for periods ending after
December 15, 1997. SFAS No. 128 replaces Accounting Principles Board Opinion
("APB") No. 15 and simplifies the computation of earnings per share ("EPS") by
replacing the presentation of primary EPS with a presentation of basic EPS.
Basic EPS includes no dilution and is computed by dividing income available to
common stockholders by the weighted-average number of common shares outstanding
for the period. Diluted EPS reflects the potential dilution from securities that
could share in the earnings of the Company, similar to fully diluted EPS under
APB No. 15. The Statement requires dual presentation of basic and diluted EPS by
entities with complex capital structures. The Company will adopt SFAS No. 128
for the financial statements for the year ended May 31, 1998.

      SFAS No. 130, "Reporting Comprehensive Income" is effective for fiscal
years beginning after December 15, 1997. SFAS No. 130 established standards for
the reporting and display of comprehensive income and its components (revenues,
expenses, gains and losses) in a full set of general-purpose financial
statements. The Statement requires that all items that are required to be
recognized under accounting standards as components of comprehensive income be
reported in a financial statement that is displayed with the same prominence as
other financial statements. The Company is evaluating the Statement's provisions
to conclude how it will present comprehensive income it its financial
statements, and has not yet determined the amounts to be disclosed. The Company
will adopt SFAS No. 130 effective June 1, 1998.

      SFAS No. 131, "Disclosures about Segments of an Enterprise and Related
Information" is effective for financial statements for periods beginning after
December 15, 1997. SFAS No. 131 establishes standards for the way that public
business enterprises report financial and descriptive information about
reportable operating segments in annual financial statements and interim
financial reports issued to stockholders. SFAS No. 131 supersedes SFAS No. 14,
"Financial Reporting for Segments of a Business Enterprise," but retains the
requirement to report information about major customers. The Company is
evaluating the new Statement's provisions to determine the additional
disclosures required in its financial statements, if any. The Company will adopt
SFAS No. 131 effective June 1, 1998.
