                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


Note 1.  Basis of Presentation

The  consolidated  financial  statements  included  herein have been prepared by
Semitool,  Inc.,  (the  "Company")  without  audit,  pursuant  to the  rules and
regulations of the United States Securities and Exchange Commission (the "SEC").
Certain  information and footnote  disclosures,  normally  included in financial
statements prepared in accordance with generally accepted accounting principles,
have been condensed or omitted as permitted by such rules and  regulations.  The
Company believes the disclosures  included herein are adequate;  however,  these
consolidated  statements  should be read in  conjunction  with the  consolidated
financial statements and the notes thereto for the year ended September 30, 1997
previously filed with the SEC on Form 10-K.

Financial information as of September 30, 1997 has been derived from the audited
financial  statements  of the  Company.  In the  opinion  of  management,  these
unaudited  financial  statements  contain  all of the  adjustments  (normal  and
recurring in nature)  necessary  to present  fairly the  consolidated  financial
position of the Company and subsidiaries  and the consolidated  results of their
operations  and their cash  flows.  The  results of  operations  for the periods
presented  may not be  indicative  of those which may be  expected  for the full
year.

In June 1997, the Financial  Accounting  Standards Board (FASB) issued Statement
of  Financial  Accounting  Standards  (SFAS) NO. 130,  "Reporting  Comprehensive
Income."  SFAS No. 130  establishes  standards  for the reporting and display of
comprehensive  income  and  its  components  in a full  set of  general  purpose
financial statements. Comprehensive income is defined as the change in equity of
a business  enterprise  during a period from  transactions  and other events and
circumstances  from nonowner sources.  The adoption of SFAS No. 130 is effective
for the Company in fiscal 1999.

In June 1997,  the FASB issued SFAS No. 131,  "Disclosures  about Segments of an
Enterprise  and  Related  Information."  SFAS  No.  131  requires  publicly-held
companies to report financial and other information about key  revenue-producing
segments of the entity for which such  information  is available and is utilized
by the chief operation decision maker.  Specific  information to be reported for
individual  segments includes profit or loss,  certain revenue and expense items
and total assets. A reconciliation of segment  financial  information to amounts
reported in the  financial  statements  is also to be provided.  SFAS No. 131 is
effective for the Company in fiscal 1999 and the form of the presentation of the
Company's financial statements has not yet been determined.


Note 2.  Principles of Consolidation

The consolidated financial statements include the accounts of Semitool, Inc. and
its  wholly-owned  subsidiaries.  All  significant  intercompany  and affiliated
accounts and transactions are eliminated in consolidation.

Note 3.  Inventories

Inventories are summarized as follows (in thousands):


                                       March 31, 1998         September 30, 1997

respectively, of finished goods inventory was transferred to property, plant and
equipment.

Note 5.   Contingency

A class action lawsuit (Case No.  DV-96-124A) was filed on February 26, 1996, in
the Montana  Eleventh  Judicial  District  Court,  Flathead  County,  Kalispell,
Montana  against  the Company and certain of its  officers  and  directors.  The
complaint  includes  allegations that the Company issued  misleading  statements
concerning  its  business  and  prospects.  The suit  seeks  injunctive  relief,
damages,  costs and other relief as the court may find appropriate.  The Company
believes  the  lawsuit  to  be  without  merit  and  is  contesting  the  action
vigorously.  However,  given the inherent  uncertainty of litigation,  insurance
issues,  and the current stage of discovery,  there can be no assurance that the
ultimate outcome will be in the Company's favor, or that if the ultimate outcome
is  not  in the  Company's  favor,  that  such  an  outcome,  the  diversion  of
management's attention, and any costs associated with the lawsuit, will not have
a material  adverse  effect on the Company's  financial  condition or results of
operations.

Note 6.  Earnings Per Common Share

In 1997, the Financial  Accounting Standards Board issued Statement of Financial
Accounting  Standards  No. 128 (SFAS  128),  "Earnings  per  Share." The Company
adopted SFAS 128 during the first quarter of fiscal 1998.  SFAS 128 replaced the
previously  required primary and fully diluted earnings per share with basic and
diluted earnings per share.  Unlike primary  earnings per share,  basic earnings
per share  excludes any dilutive  effects of options,  warrants and  convertible
securities. Diluted earnings per share is calculated in a manner that is similar
to the previously  reported fully diluted  earnings per share.  All earnings per
share amounts for all periods have been presented to conform to the requirements
of SFAS 128.

The following table sets forth the computation of basic and diluted earnings per
share (in thousands):

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

CAUTION

Statements contained in this "Management's  Discussion and Analysis of Financial
Condition and Results of Operations"  and elsewhere in this report which are not
historical facts are  forward-looking  statements  within the meaning of Section
21E of the  Securities  Exchange  Act of 1934,  as  amended.  A  forward-looking
statement may contain words such as "will  continue to be," "will be," "continue
to," "expect to,"  "anticipates  that," "to be" or "can impact." Forward looking
statements include:  the Company's statement in Part I, Item 2 under the heading
"Liquidity  and  Capital  Resources"  regarding  its  belief  that cash and cash
equivelents, funds generated from operations, and borrowings under the Company's
line of credit  agreements  will be  sufficient  to meet the  Company's  planned
requirements  for the  balance  of the fiscal  year.  Management  cautions  that
forward-looking  statements  are subject to risks and  uncertainties  that could
cause the Company's actual results to differ  materially from those projected in
such forward-looking statements.  These risks and uncertainties include, but are
not limited to, the cyclical  nature of the  semiconductor  industry in general,
lack of market acceptance for new products,  decreasing demand for the Company's
existing  products,   impact  of  competitive  products  and  pricing,   product
development,  commercialization  and  technological  difficulties,  capacity and
supply  constraint  difficulties and other risks detailed herein.  The Company's
future  results  will depend on its ability to continue to enhance its  existing
products  and to develop  and  manufacture  new  products  and to  finance  such
activities. There can be no assurance that the Company will be successful in the
introduction,  marketing and  cost-effective  manufacture of any new products or
that the Company will be able to develop and  introduce  in a timely  manner new
products or  enhancements  to its existing  products and processes which satisfy
customer needs or achieve widespread market acceptance.

The Company  undertakes no obligation  to release  revisions to  forward-looking
statements  to  reflect  subsequent  events,  changed   circumstances,   or  the
occurrence of unanticipated events.


RESULTS OF OPERATIONS

SECOND QUARTER OF FISCAL YEAR 1998 COMPARED WITH SECOND QUARTER OF
FISCAL YEAR 1997

Net Sales.  Net sales  consist of revenues  from sales of  equipment,  including
associated spare parts and service contracts,  and software products.  Net sales
were $45.2 million in the second  quarter of fiscal year 1998  essentially  even
with sales for the same  period in fiscal year 1997.  Sales of vertical  thermal
processors,  spare parts,  single wafer  processors,  including  electrochemical
deposition  tools,  and  software  were higher in the  current  quarter but that
increase was offset by lower shipments of batch wet processing tools.

Gross Profit.  Gross profit margin was 52.7% of net sales in the second  quarter
of fiscal year 1998 compared to 46.2% of net sales for the same period in fiscal
year 1997.  Lower warranty and  manufacturing  costs were the primary factors in
this increase.  The Company's gross profit margin has been, and will continue to
be,  affected by a variety of  factors,  including  the mix and average  selling
price of products sold, and the cost to manufacture, service and support new and
enhanced products.

Selling,  General  and  Administrative.   Selling,  general  and  administrative
expenses  were  $14.5  million  or 32.0% of net sales in the  second  quarter of
fiscal year 1998  compared  to $11.3  million or 25.1% of net sales for the same
period in fiscal year 1997. The increase in selling,  general and administrative
expense is primarily  attributable to the larger  infrastructure put in place to
support the Asian and  domestic  markets,  and the growing  installed  base of a
broader range of  equipment.  A  substantial  portion of the Company's  selling,
general and administrative  expenses are fixed in the short term and as such may
fluctuate as a percentage of net sales from period to period.

Research and Development. Research and development expenses consist of salaries,
project  materials,   laboratory  costs,  professional  fees,  and  other  costs
associated  with the Company's  research and development  efforts.  Research and
development expense was $6.9 million or 15.2% of net sales in the second quarter
of fiscal year 1998  compared to $5.3  million or 11.8% of net sales in the same
period in fiscal year 1997. The Company's  development  efforts  associated with
its electrochemical deposition tool and software products for fab equipment data
collection, analysis and control accounted for most of the increase.

The Company is committed to technology leadership in the semiconductor equipment
industry  and  expects to  continue  to fund  research  and  development  with a
multiyear  perspective.  The Company's  research and  development  expenses have
fluctuated from quarter to quarter in the past and this  fluctuation is expected
to  continue  in  the  future,  both  in the  absolute  dollar  amount  and as a
percentage of net sales.

Other Income (Expense),  Net. Other income  (expense),  net was a net expense of
$204,000 in the second  quarter of fiscal year 1998 compared to a net expense of
$17,000 for the same period in fiscal year 1997. Interest expense is the largest
contributor to the increase and interest  expense  exceeded  interest  income in
both periods.

Provision for Income Taxes.  Income tax provisions are made based on the blended
estimate of federal, state and foreign effective income tax rates.

Orders Backlog. The Company includes in its orders backlog those customer orders
for which it has received purchase orders or purchase order numbers and shipment
is scheduled  within the next twelve months.  Orders  backlog was  approximately
$63.2 million at March 31, 1998 compared to approximately $81.7 million at March
31, 1997 and $63.8 million at the beginning of the current fiscal year.

Orders are generally  subject to  cancellation or rescheduling by customers with
limited or no  penalty.  As the result of tools  ordered and shipped in the same
quarter,  changes in customer  delivery  schedules,  cancellations of orders and
delays in product shipments, the Company's orders backlog at any particular date
is not necessarily indicative of actual sales for any succeeding period.

SIX MONTHS OF FISCAL YEAR 1998 COMPARED WITH SIX MONTHS OF FISCAL YEAR 1997

Net Sales. Net sales increased 5.1% to $92.2 million in the first half of fiscal
year 1998 from $87.7 million for the same period in fiscal year 1997.  Increased
shipments of vertical thermal processors,  spare parts, single wafer processors,
including electrochemical deposition tools, and software products were partially
offset by decreases in shipments of batch wet processing tools.

Gross  Profit.  Gross profit  margin was 51.8% of net sales in the first half of
fiscal  year 1998  compared  to 45.6% of net sales for the same period in fiscal
year 1997.  Reduced  manufacturing  costs,  lower  warranty  costs in the second
quarter and performance  based  incentives  earned in the first quarter were the
most significant  factors in the increase in gross profit margin.  The Company's
gross profit margin has been, and will continue to be,  affected by a variety of
factors,  including the mix and average  selling price of products sold, and the
cost to manufacture, service and support new and enhanced products.

Selling,  General  and  Administrative.   Selling,  general  and  administrative
expenses  were  $28.2  million or 30.6% of net sales in the first half of fiscal
year 1998 compared to $21.8 million or 24.9% of net sales for the same period in
fiscal  year 1997.  The 5.7%  increase in  selling,  general and  administrative
expenses  relative to net sales  consists  primarily of a 4.7% increase in sales
and service  expenses due to the larger  infrastructure  put in place to support
both the Asian and domestic markets,  and the larger installed base of a broader
range of equipment.

Research and Development.  Research and development expense was $13.0 million or
14.1% of net sales in the  first  half of fiscal  year  1998  compared  to $10.3
million  or 11.7% of net sales for the same  period in  fiscal  year  1997.  The
increase in spending on research and development for the first six months of the
current fiscal year was primarily associated with the Company's  electrochemical
deposition tool  development  and the  development of software  products by Semy
Engineering, Inc., a wholly-owned subsidiary of the Company.

Other Income (Expense),  Net. Other income  (expense),  net was a net expense of
$143,000  in the first half of fiscal  year 1998  compared  to a net  expense of
$72,000  for the same  period in fiscal  year 1997.  Interest  expense  exceeded
interest  income in the first  half of fiscal  year 1998 and  accounted  for the
majority of the change.

Provision for Income Taxes.  Income tax provisions are made based on the blended
estimate of federal, state and foreign effective income tax rates. The effective
income tax rate for the first half of fiscal  year 1998 was 37%  compared to 38%
for the comparable period in fiscal year 1997.

Year 2000 Software System Status. The Company has conducted a preliminary review
of its software systems for year 2000 compliance. This includes software used by
the Company and the software  developed by the Company that is  incorporated  in
the tools that it sells to customers. The tests completed to date show that most
of the Company's software is year 2000 compliant and will operate as is, or with
minor  modifications.  The Company will continue to test its software,  but does
not anticipate major year 2000 compliance problems at this time. There can be no
assurance, however, that the Company will not experience unanticipated year 2000
compliance  difficulties  that  could  have a  material  negative  impact on the
Company's operations.

Recently  Issued  Accounting  Standards.  Recently issued  accounting  standards
include Statement of Financial Accounting Standards (SFAS) No. 128 "Earnings Per
Share," issued by the Financial  Accounting  Standards  Board (FASB) in February
1997,  SFAS  No.  130  "Reporting   Comprehensive   Income"  and  SFAS  No.  131
"Disclosures about Segments of an Enterprise and Related Information," issued by
the FASB in June 1997.  SFAS No. 128 was first effective for the Company for its
interim  period ended  December 31, 1997.  Basic and diluted  earnings per share
pursuant to the  requirements  of SFAS No. 128 are  presented on the face of the
income statement and in the notes to the financial  statements.  Descriptions of
SFAS  No.  130 and SFAS  No.  131 are  included  in the  notes to the  financial
statements.


LIQUIDITY AND CAPITAL RESOURCES

Cash  provided by  operations  was $4.8  million  during the first six months of
fiscal year 1998, compared to $3.9 million provided in the same period in fiscal
year 1997.  Inventories  rose  slightly  to $41.7  million  during the first six
months of fiscal year 1998 from $41.1 million at September 30, 1997.  During the
same period,  trade receivables  decreased $4.7 million, net of foreign currency
translation  effects,  mainly  due to the  timing of  collections.  The  Company
expects future working  capital  components to fluctuate  based on net sales and
the manufacturing cycle time of the specific equipment types being produced.

Investing activities consisted primarily of $6.8 million of property,  plant and
equipment  acquisitions,  and $1.0  million for  internally  developed  software
products included in intangible assets. The expenditures for property, plant and
equipment  included  the  purchase  of land to be used as a site  for an  office
building for Semy Engineering,  Inc., a wholly-owned  subsidiary,  which markets
software products for semiconductor fab automation, and a manufacturing facility
for Rhetech, Inc., a wholly-owned subsidiary, which refurbishes and markets used
semiconductor  equipment.  New  financing  in the  amount  of $1.1  million  was
obtained for the Rhetech facility  purchase.  The financing included a $540,000,
ten year loan with monthly pricipal and interest payments, a fixed interest rate
of 7.50% for seven years,  and a variable  interest rate of one percentage point
above the lender's  then current  prime rate for the  remaining  three years.  A
$560,000  bridge loan was  provided  by the same lender with a maturity  date of
September  3, 1998 and it is  expected  to be  repaid  from the  proceeds  of an
industrial development  association loan. Financing activity under the Company's
revolving  line of credit  resulted in new net  borrowings of $1.0 million,  and
borrowings of $5.0 million were outstanding  under this credit facility at March
31, 1998.

As of March 31, 1998, the Company's  principal sources of liquidity consisted of
approximately $4.2 million of cash and cash equivalents,  $5.0 million available
under the Company's  $10.0 million  revolving line of credit,  and $15.0 million
under its  long-term  credit  facility.  The revolving  line of credit  facility
expires  on March 31,  1999,  when all  principal  amounts  owing  are due.  The
long-term credit facility expires on December 31, 1999, with amounts outstanding
repayable in monthly  principal and interest  payments  over a five-year  period
ending December 2004.

The  Company  believes  that cash and cash  equivalents,  funds  generated  from
operations,  and  borrowings  under  its  line  of  credit  agreements  will  be
sufficient to meet the Company's planned capital requirements for the balance of
the fiscal year.  Total  purchases of property,  plant and  equipment for fiscal
year 1998 are expected to be  approximately  $13.0  million  excluding any major
facility  expansion.  The Company has plans to build an office  building for its
software  business but has not  determined  when,  or if, that project will move
forward.  Additionally,  the Company has formulated  preliminary expansion plans
for other areas of its business which can be triggered quickly.  Any decision to
implement a major facility expansion,  to add an additional facility,  to invest
in  or  acquire  complementary  businesses,  products,  or  technology,  or  any
significant  increase in working capital to fund such growth could result in the
Company effecting  additional  equity or debt financing.  The sale of additional
equity securities or the issuance of equity securities in a business combination
could result in dilution to the Company's shareholders.


LITIGATION

A class action lawsuit (Case No. DV-96-124A) was filed February 26, 1996, in the
Montana Eleventh Judicial District Court,  Flathead County,  Kalispell,  Montana
against the Company and certain of its officers  and  directors.  The  complaint
includes  allegations that the Company issued misleading  statements  concerning
its business and prospects. The suit seeks injunctive relief, damages, costs and
other relief as the court may find appropriate. The Company believes the lawsuit
to be without merit and is contesting the action vigorously.  However, given the
inherent  uncertainty of litigation,  insurance issues, and the current stage of
discovery,  there can be no assurance  that the ultimate  outcome will be in the
Company's  favor, or that if the ultimate outcome is not in the Company's favor,
that such an outcome,  the diversion of  management's  attention,  and any costs
associated  with the  lawsuit,  will not have a material  adverse  effect on the
Company's financial condition or results of operations.
