MKS INSTRUMENTS, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Tables in thousands, except per share data)


1) BASIS OF PRESENTATION

The interim financial data as of June 30, 2001 and for the three and six
months ended June 30, 2001 and 2000 is unaudited; however, in the opinion
of MKS Instruments, Inc., the interim data includes all adjustments,
consisting only of normal recurring adjustments, necessary for a fair
presentation of the results for the interim periods. The terms "MKS" and
the "Company" refer to MKS Instruments, Inc. and subsidiaries, including
Applied Science and Technology, Inc. ("ASTeX"). The unaudited financial
statements presented herein have been prepared in accordance with the
instructions to Form 10-Q and do not include all the information and note
disclosures required by generally accepted accounting principles. The
financial statements should be read in conjunction with the December 31,
2000 audited financial statements and notes thereto included in the MKS
Annual Report on Form 10-K filed with the Securities and Exchange
Commission on April 2, 2001 and the MKS Current Reports on Form 8-K filed
with the Securities and Exchange Commission on April 20, 2001.

On January 26, 2001, MKS completed its acquisition of ASTeX in a
transaction accounted for under the pooling of interests method of
accounting. Under the terms of the agreement, each outstanding share of
ASTeX common stock was exchanged for 0.7669 newly issued shares of common
stock of MKS Instruments, Inc., resulting in the issuance of approximately
11.2 million shares of common stock of MKS Instruments, Inc., representing
approximately 30% of its then outstanding shares. There were no material
adjustments required to conform the accounting policies of the two
companies. The unaudited financial statements for the three months and six
months ended June 30, 2000 combine the historical financial statements of
MKS Instruments, Inc. for the three months and six months ended June 30,
2000 with the historical financial statements of ASTeX for the three months
and six months ended December 25, 1999. The following table presents
details of the results of operations for the separate companies.

MKS Instruments, Inc. ASTeX
Three months ended Three months ended
June 30, 2000 December 25, 1999 COMBINED
-------------------- ------------------ --------
Net sales ..... $77,701 $31,066 $108,767
Net income .... $11,286 $ 3,163 $ 14,449


MKS Instruments, Inc. ASTeX
Six months ended Six months ended
June 30, 2000 December 25, 1999 COMBINED
-------------------- ------------------ --------
Net sales ..... $143,257 $61,668 $204,925
Net income .... $ 20,617 $ 5,791 $ 26,408

The December 31, 2000 Balance Sheet combines the balance sheet of MKS
Instruments, Inc. as of December 31, 2000 with the balance sheet of ASTeX
as of July 1, 2000.

As a result of conforming dissimilar fiscal year-ends, the ASTeX results of
operations for the six-month period ended December 31, 2000 are excluded
from the consolidated financial statements of MKS for the year ended
December 31, 2000. The following is information related to the ASTeX
financial results for the six-month period ended December 31, 2000:

Net sales ........................................ $ 89,193
Net income ....................................... 5,968
Net cash used by operating activities ............ (3,500)
Net cash provided by investing activities ........ 245
Net cash provided by financing activities ........ 43

MKS INSTRUMENTS, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (Continued)
(Tables in thousands, except per share data)


Included in stockholders' equity at June 30, 2001 is a $5,968,000
adjustment resulting from conforming the two companies' dissimilar year
ends, which represents the ASTeX results of operations for the six-month
period ended December 31, 2000.

2) USE OF ESTIMATES

The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the dates of the
financial statements and the reported amounts of revenues and expenses
during the reporting periods. Actual results could differ from those
estimates.

3) RECENT ACCOUNTING PRONOUNCEMENTS

In July 2001, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards No. 141 ("SFAS 141"), "Business
Combinations." SFAS 141 requires the purchase method of accounting for
business combinations initiated after June 30, 2001 and eliminates the
pooling of interests method.

In July 2001, the FASB issued Statement of Financial Accounting Standards
No. 142 ("SFAS 142"), "Goodwill and Other Intangible Assets", which is
effective for MKS on January 1, 2002. SFAS 142 requires, among other
things, the discontinuance of goodwill amortization and includes provisions
for the reclassification of certain existing recognized intangibles as
goodwill, reassessment of the useful lives of existing recognized
intangibles, and reclassification of certain intangibles out of previously
reported goodwill. SFAS 142 also requires the Company to complete a
transitional goodwill impairment test six months from the date of adoption.
As a result of implementing SFAS 142, the Company expects to stop
amortizing goodwill effective January 1, 2002 but will continue to amortize
other intangible assets. The Company is currently reviewing the potential
additional impact of SFAS 142 on its financial position and results of
operations.

</TABLE>

For purposes of computing diluted earnings per share, weighted average
common share equivalents do not include stock options with an exercise
price greater than the average market price of the common shares during the
period. Options to purchase 109,000 and 76,000 shares of common stock which
were outstanding during the three and six months ended June 30, 2000,
respectively, were not included in the calculation of diluted net income
per common share because the option price was greater than the average
market price of the common shares during the period. All options
outstanding during the three and six months ended June 30, 2001 are
excluded from the calculation of diluted net income per common share
because their inclusion would be anti-dilutive. There were options to
purchase approximately 5,168,000 shares of the Company's common stock
outstanding as of June 30, 2001.

9) ACQUISITIONS

On April 27, 2001 (the effective date of purchase), MKS completed its
acquisition of On-Line Technologies, Inc. ("On-Line"), a supplier of
measurement and control products used for gas analysis, wafer metrology and
process control. The acquisition has been accounted for under the purchase
method of accounting. The purchase price was approximately $23,829,000 and
consisted of approximately 660,000 shares of MKS common stock valued at
approximately $12,110,000, cash payments of $6,295,000, assumption of
On-Line debt of approximately $4,728,000 and transaction expenses of
approximately $696,000. The purchase price was allocated to the assets
acquired based upon their estimated fair values and resulted in an
allocation of approximately $16,050,000 to goodwill. The results of
operations are included in the Company's consolidated statement of income
(loss) as of and since the effective date of the purchase. The allocation
of the purchase price was as follows:

Fair value of tangible assets and liabilities assumed ... $ (971)

goodwill are being amortized using the straight-line method over their
respective estimated useful lives, which range from 5 to 7 years.

In connection with the acquisition of On-Line, the Company obtained an
appraisal from an independent appraiser of the fair value of its intangible
assets. This appraisal valued purchased in-process research and development
("IPR&D") of various projects for the development of new products and
technologies at approximately $2,340,000. Because the technological
feasibility of products under development had not been established and no
future alternative uses existed, the purchased IPR&D was written off during
the quarter ended June 30, 2001. The value of the purchased IPR&D was
determined using the income approach, which discounts expected future cash
flows from projects under development to their net present value. Each
project was analyzed to determine the technological innovations included;
the utilization of core technology; the complexity, cost and time to
complete development; any alternative future use or current technological
feasibility; and the stage of completion. The cash flows derived from the
in-process technology projects were discounted at a rate of 25%. The
Company believes this rate was appropriate given the risks associated with
the technologies for which commercial feasibility had not been established.
The percentage of completion for each in-process project was determined by
identifying the elapsed time invested in the project as a ratio of the
total time required to bring the project to technical and commercial
feasibility. The percentage of completion for in-process projects acquired
ranged from 55% to 65%, based on management's estimates of tasks completed
and the tasks to be completed to bring the projects to technological and
commercial feasibility. As of June 30, 2001, the actual development
timelines and costs were in line with management's estimates.

Development of in-process technology remains a substantial risk to the
Company due to a variety of factors including the remaining effort to
achieve technical feasibility, rapidly changing customer requirements and
competitive threats from other companies and technologies.

The unaudited pro forma results for the six months ended June 30, 2001
exclude approximately $6.4 million of non-recurring charges directly
related to the transaction that were incurred by On-Line prior to the date
of the acquisition. Additionally, the charge for purchased IPR&D was not
included in the unaudited pro forma results, because it was non-recurring
and directly related to the transaction.

These unaudited pro forma results have been prepared for comparative
purposes only and do not purport to be indicative of the results of
operations which actually would have resulted had the acquisition occurred
at the beginning of the period, or which may result in the future.

10) GOODWILL IMPAIRMENT CHARGE

In August 1999, ASTeX purchased Shamrock product group for approximately
$6.4 million in cash. The costs of the acquisition were allocated on the
basis of the estimated fair market value of the assets acquired at that
time, and resulted in an allocation of $4,463,000 to goodwill.

When the Company acquired the Shamrock product line, it was expected that
sales of the existing system design and development of new system designs
would generate future revenues. Since the acquisition, the Company has
provided potential customers with purchase quotations for Shamrock systems,
including a significant quotation to a potential customer in January 2001
for the sale of several systems. The customer did not purchase the systems,
and the quotation expired in March 2001. The Company has been unsuccessful
in selling any systems of the product line since the acquisition and, with
the expiration of the significant quote in March 2001, believes that future
Shamrock system sales will not be sufficient to recover the carrying value
of the goodwill. Additionally, the Company has no current plans for future
development of new system designs. Consequently, the Company believed that
the carrying amount of the Shamrock related goodwill was impaired. To
measure the impairment, the Company performed a cash flow analysis for the
product group and determined that the estimated future cash flows of the
group would be insignificant. As a result, the Company wrote-off the
carrying value of the related goodwill of approximately $3,720,000 in the
quarter ended March 31, 2001.

11) MERGER COSTS

On January 26, 2001 MKS completed its acquisition of ASTeX in a transaction
accounted for under the pooling of interests method of accounting. Under
the pooling of interests method of accounting, fees and expenses related to
the merger are expensed in the period of the merger. During the three
months ended March 31, 2001, MKS expensed approximately $7.7 million of
merger related expenses, consisting of $6.9 million of investment banking,
legal, accounting, printing and other professional fees, and $0.8 million
of regulatory and other costs.

On April 27, 2001 (the effective date of purchase) MKS completed its acquisition
of On-Line Technologies, Inc. ("On-Line"), a supplier of measurement and control
products used for gas analysis, wafer metrology and process control. The
acquisition has been accounted for under the purchase method of accounting. The
purchase price was approximately $23,829,000 and consisted of approximately
660,000 shares of MKS common stock valued at approximately $12,110,000, cash
payments of $6,295,000, assumption of On-Line debt of approximately $4,728,000
and transaction expenses of approximately $696,000. Accordingly, the estimated
fair value of assets acquired and liabilities assumed were included in the
Company's consolidated balance sheet as of the effective date of the purchase.
The results of operations are included in the Company's consolidated statement
of income (loss) as of and since the effective date of the purchase.

MKS develops, manufactures and supplies gas measurement, control and analysis
products, reactive gas generator and power delivery products used in
semiconductor manufacturing and other advanced thin-film manufacturing
processes. We estimate that during 2000 approximately 76% of our net sales were
to semiconductor capital equipment manufacturers and semiconductor device
manufacturers. The following table sets forth for the periods indicated the

Results of Operations

Net Sales. Net sales decreased 33.2% to $72.7 million for the three months
ended June 30, 2001 from $108.8 million for the three months ended June 30,
2000. International net sales were approximately $23.6 million for the three
months ended June 30, 2001 or 32.5% of net sales and $25.7 million for the same
period of 2000 or 23.6% of net sales. Net sales decreased 10.4% to $183.5
million for the six months ended June 30, 2001 from $204.9 million for the same
period of 2000. International net sales were approximately $53.3 million for the
six months ended June 30, 2001 or 29.1% of net sales and $47.5 million for the
same period of 2000 or 23.2% of net sales. The decrease in net sales is due to a
worldwide slowdown in demand for semiconductors during 2001 which resulted in a
decline in demand for the Company's products from the Company's semiconductor
capital equipment manufacturers and semiconductor device manufacturer customers.

Gross Profit. Gross profit as a percentage of net sales decreased to 35.5%
for the three months ended June 30, 2001 from 45.0% for the three months ended
June 30, 2000. Gross profit as a percentage of net sales decreased to 37.6% for
the six months ended June 30, 2001 from 44.0% for the same period of 2000. The
decrease was primarily due to lower absorption of manufacturing overhead costs.
Additionally, gross margins were negatively effected by a $2.6 million write-off
of obsolete and excess inventory in the second quarter of 2001. This write-off
was significantly higher than normal and was primarily caused by a significant
reduction in demand, including reduced demand for older technology products.

Research and Development. Research and development expense increased 3.7%
to $9.5 million or 13.0% of net sales for the three months ended June 30, 2001
from $9.1 million or 8.4% of net sales for the three months ended June 30, 2000.
The increase was primarily due to increased compensation expense. Research and
development expense increased 26.9% to $20.6 million or 11.2% of net sales for
the six months ended June 30, 2001 from $16.2 million or 7.9% of net sales for
the same period of 2000. The increase was primarily due to increased
compensation expense.

Selling, General and Administrative. Selling, general and administrative
expenses increased 4.4% to $17.6 million or 24.2% of net sales for the three
months ended June 30, 2001 from $16.8 million or 15.5% of net sales for the
three months ended June 30, 2000. The increase was due primarily to increased
professional fees. Selling, general and administrative expenses increased 14.3%
to $36.6 million or 20.0% of net sales for the six months ended June 30, 2001
from $32.1 million or 15.6% of net sales for the same period of 2000. The
increase was due primarily to increased professional fees of $2.0 million,
compensation expense of $1.0 million related to the earnout from the Spectra
acquisition, and other selling, general, and administrative expenses.

Amortization of Goodwill and Acquired Intangible Assets. Amortization of
goodwill and acquired intangible assets of $2.7 million and $5.0 million for the
three and six months ended June 30, 2001, respectively, represents the
amortization of goodwill and other intangibles resulting from the acquisitions
completed by MKS.

Goodwill Impairment Charge. In August 1999, ASTeX purchased the Shamrock
product group for approximately $6.4 million in cash. The costs of the
acquisition were allocated on the basis of the estimated fair market value of
the assets acquired at that time, and resulted in an allocation of $4,463,000 to
goodwill.

When the Company acquired the Shamrock product line, it was expected that
sales of the existing system design and development of new system designs would
generate future revenues. Since the acquisition, the Company has provided
potential customers with purchase quotations for Shamrock systems, including a
significant quotation to a potential customer in January 2001 for the sale of
several systems. The customer did not purchase the systems, and the quotation
expired in March 2001. The Company has been unsuccessful in selling any systems
of the product line since the acquisition and, with the expiration of the
significant quote in March 2001, believes that future Shamrock system sales will
not be sufficient to recover the carrying value of the goodwill. Additionally,
the Company has no current plans for future development of new system designs.
Consequently, the Company believed that the carrying amount of the Shamrock
related goodwill was impaired. To measure the impairment, the Company performed
a cash flow analysis for the product group and determined that the estimated
future cash flows of the group would be insignificant. As a result, the Company
wrote-off the carrying value of the related goodwill of approximately $3,720,000
in the quarter ended March 31, 2001.
14

Merger Costs. On January 26, 2001 MKS completed its acquisition of ASTeX in
a transaction accounted for under the pooling of interests method of accounting.
Under the pooling of interests method of accounting, fees and expenses related
to the merger are expensed in the period of the merger. During the six months
ended June 30, 2001, MKS expensed approximately $7.7 million of merger related
expenses, consisting of $6.9 million of investment banking, legal, accounting,
printing and other professional fees, $0.8 million of regulatory and other
costs.

Purchase of In-process Technology. In April 2001, the Company acquired
On-Line in a transaction accounted for as a purchase. The purchase price was
allocated to the assets acquired, including intangible assets, based on their
estimated fair values. The intangible assets include approximately $2.3 million
for acquired in-process technology for projects that did not have future
alternative uses. The value of the purchased in-process technology was
determined using the income approach, which discounts expected future cash flows
from projects under development to their net present value. Each project was
analyzed to determine the technological innovations included; the utilization of
core technology; the complexity, cost and time to complete development; any
alternative future use or current technological feasibility; and the stage of
completion. At the date of the acquisition, the development of these projects
had not yet reached technological feasibility, and the technology in progress
had no alternative future uses. Accordingly, these costs were expensed in the
three months ended June 30, 2001.

Interest Income (Expense), Net. During the three and six months ended June
30, 2001, the Company generated net interest income of $1.0 million and $2.4
million, respectively, primarily from the invested net proceeds of its common
stock offerings, offset by interest expense on outstanding debt.

Provision for Income Taxes. The effective tax rates for the three and six
months ended June 30, 2001 were 21.0% and 37.4%, respectively, resulting in an
income tax benefit of $1.1 million and income expense of $1.7 million,
respectively. The changes in effective tax rates for the three and six months
ended June 30, 2001 as compared to the effective tax rates for the three and six
months ended June 30, 2000 were primarily due to non-deductible charges
associated with acquisitions made in 2001.

LIQUIDITY AND CAPITAL RESOURCES

The Company has financed its operations and capital requirements through a
combination of cash provided by operations, long-term real estate financing,
capital lease financing and short-term lines of credit. On April 5, 1999, MKS
completed the initial public offering of its Common Stock. In connection with
this offering and the exercise of an over-allotment option by the underwriters,
MKS sold 6,375,000 shares of Common Stock at a price of $14.00 per share. The
net proceeds to MKS were approximately $82,000,000 and were received in the
second quarter of 1999. Underwriting discounts and commissions were
approximately $6,200,000, and other offering costs were approximately
$1,000,000. On April 5, 1999, MKS distributed $40,000,000, which was the
estimated amount of its undistributed S Corporation earnings as of the day prior
to the closing of the offering.

On March 30, 2000, ASTeX completed the registration and sale of 1,917,250 shares
of common stock at $40.42 per share. The net proceeds from the offering were
approximately $73.2 million.

On March 5, 1999, ASTeX completed the registration and sale of 1,533,800 shares
of common stock at $14.34 per share. On April 6, 1999, the underwriters
exercised their over-allotment option to purchase an additional 230,070 shares
of common stock. The net proceeds from the offering were approximately $23.8
million.

In 1998, ASTeX announced that it had met the requirements for the redemption of
redeemable warrants issued in connection with the ASTeX initial public offering
and called the warrants for redemption. 2,082,451 redeemable warrants and
133,088 underwriter warrants were converted into 1,297,147 shares of common
stock. The net proceeds were $15,234,000.

Working capital was $223.7 million as of June 30, 2001, a decrease of $13.6
million from December 31, 2000. Operations provided cash of $14.8 million for
the six months ended June 30, 2001. This cash flow was impacted by the net loss,
depreciation and amortization, the goodwill impairment charge and changes in the
levels of accounts payable, accrued expenses, and accounts receivable. Investing
activities utilized cash of $17.9 million for the six months ended June 30, 2001
primarily from the purchases of On-Line and property, plant, and equipment.
Financing activities utilized cash of $0.4 million, primarily from payments on
short-term borrowings offset by proceeds from employees exercising stock
options.
15

The Company believes that its working capital, together with the cash
anticipated to be generated from operations and funds available from existing
credit facilities, will be sufficient to satisfy its estimated working capital
and planned capital expenditure requirements through at least the next 12
months.

FACTORS THAT MAY AFFECT FUTURE RESULTS

MKS believes that this document contains "forward-looking statements" within the
meaning of the Private Securities Litigation Reform Act of 1995. These
statements are subject to risks and uncertainties and are based on the beliefs
and assumptions of management of MKS, based on information currently available
to MKS's management. Use of words such as "believes," "expects," "anticipates,"
"intends," "plans," "estimates," "should," "likely" or similar expressions,
indicate a forward-looking statement. Forward-looking statements involve risks,
uncertainties and assumptions. Certain of the information contained in this
Quarterly Report on Form 10-Q consists of forward-looking statements. Important
factors that could cause actual results to differ materially from the
forward-looking statements include the following:

MKS' BUSINESS DEPENDS SUBSTANTIALLY ON CAPITAL SPENDING IN THE SEMICONDUCTOR
INDUSTRY WHICH IS CHARACTERIZED BY PERIODIC FLUCTUATIONS THAT MAY CAUSE A
REDUCTION IN DEMAND FOR MKS' PRODUCTS.

MKS estimates that approximately 76% of its sales in 2000 were to semiconductor
capital equipment manufacturers and semiconductor device manufacturers, and it
expects that sales to such customers will continue to account for a substantial
majority of its sales. MKS' business depends upon the capital expenditures of
semiconductor device manufacturers, which in turn depend upon the demand for
semiconductors. Periodic reductions in demand for the products manufactured by
semiconductor capital equipment manufacturers and semiconductor device
manufacturers may adversely affect MKS' business, financial condition and
results of operations. Historically, the semiconductor market has been highly
cyclical and has experienced periods of overcapacity, resulting in significantly
reduced demand for capital equipment. For example, in 1996 and 1998, the
semiconductor capital equipment industry experienced significant declines, which
caused a number of MKS customers to reduce their orders. More recently, in the
first and second quarters of 2001, MKS experienced a significant reduction in
demand from OEM customers, and lower gross margins due to reduced absorption of
manufacturing overhead at the lower revenue levels. In addition, many
semiconductor manufacturers have operations and customers in Asia, a region
which in recent years has experienced serious economic problems including
currency devaluations, debt defaults, lack of liquidity and recessions. MKS
cannot be certain that semiconductor downturns will not recur. A decline in the
level of orders as a result of any current and future downturn or slowdown in
the semiconductor capital equipment industry could have a material adverse
effect on MKS' business, financial condition and results of operations.

MKS' QUARTERLY OPERATING RESULTS HAVE VARIED, AND ARE LIKELY TO CONTINUE TO VARY
SIGNIFICANTLY. THIS MAY RESULT IN VOLATILITY IN THE MARKET PRICE FOR MKS'
SHARES.

A substantial portion of MKS' shipments occur shortly after an order is received
and therefore MKS operates with a low level of backlog. As a result, a decrease
in demand for MKS' products from one or more customers could occur with limited
advance notice and could have a material adverse effect on MKS' results of
operations in any particular period. A significant percentage of MKS' expenses
are relatively fixed and based in part on expectations of future net sales. The
inability to adjust spending quickly enough to compensate for any shortfall
would magnify the adverse impact of a shortfall in net sales on MKS' results of
operations. Factors that could cause fluctuations in MKS' net sales include:

- - the timing of the receipt of orders from major customers;

- - shipment delays;

- - disruption in sources of supply;

- - seasonal variations of capital spending by customers;

- - production capacity constraints; and

- - specific features requested by customers.

For example, MKS was in the process of increasing its production capacity when
the semiconductor capital equipment market began to experience a significant
downturn in 1996. This downturn had a material adverse effect on MKS' operating
results in the second half of 1996 and the first half of 1997. After an increase
in business in the latter half of 1997, the market experienced another downturn
in 1998, which had a material adverse effect on MKS' 1998 and first quarter 1999
operating results. More recently, the semiconductor capital equipment market has
experienced a significant downturn during 2001. As a result, MKS experienced a
reduction in demand from OEM customers in the first and second quarters of 2001,
which had a material adverse effect on MKS' operating results. As a result of
the factors discussed above, it is likely that MKS will in the future experience
quarterly or annual fluctuations and that, in one or more future
17

quarters, its operating results will fall below the expectations of public
market analysts or investors. In any such event, the price of MKS' common stock
could decline significantly.

THE LOSS OF NET SALES TO ANY ONE OF MKS' MAJOR CUSTOMERS WOULD LIKELY HAVE A
MATERIAL ADVERSE EFFECT ON MKS.

MKS' five largest customers accounted for approximately 45% of its net sales in
2000, 39% of its net sales in 1999 and 34% of its net sales in 1998. The loss of
a major customer or any reduction in orders by these customers, including
reductions due to market or competitive conditions, would likely have a material
adverse effect on MKS' business, financial condition and results of operations.
During 2000 and 1999, one customer, Applied Materials, accounted for
approximately 30% and 29%, respectively, of MKS' net sales. MKS' purchase
contract with Applied Materials expires in 2004. None of MKS' significant
customers, including Applied Materials, has entered into an agreement requiring
it to purchase any minimum quantity of MKS' products. The demand for MKS'
products from its semiconductor capital equipment customers depends in part on
orders received by them from their semiconductor device manufacturer customers.

Attempts to lessen the adverse effect of any loss or reduction through the rapid
addition of new customers could be difficult because prospective customers
typically require lengthy qualification periods prior to placing volume orders
with a new supplier. MKS' future success will continue to depend upon:

- - its ability to maintain relationships with existing key customers;

- - its ability to attract new customers; and

- - the success of its customers in creating demand for their capital equipment
products which incorporate MKS's products.

AS PART OF MKS' BUSINESS STRATEGY, MKS HAS ENTERED INTO AND MAY ENTER INTO OR
SEEK TO ENTER INTO BUSINESS COMBINATIONS AND ACQUISITIONS THAT MAY BE DIFFICULT
TO INTEGRATE, DISRUPT ITS BUSINESS, DILUTE STOCKHOLDER VALUE OR DIVERT
MANAGEMENT ATTENTION.

MKS acquired Compact Instrument Technology ("Compact Instrument") in March 2000,
Telvac Engineering, Ltd. ("Telvac") in May 2000, Spectra Instruments, Inc.
("Spectra") in July 2000, D.I.P., Inc. ("D.I.P.") in September 2000, ASTeX in
January 2001 and On-Line in April 2001. As a part of its business strategy, MKS
may enter into additional business combinations and acquisitions. Acquisitions
are typically accompanied by a number of risks, including the difficulty of
integrating the operations and personnel of the acquired companies, the
potential disruption of MKS' ongoing business and distraction of management,
expenses related to the acquisition and potential unknown liabilities associated
with acquired businesses.

If MKS is not successful in completing acquisitions that it may pursue in the
future, it may be required to reevaluate its growth strategy and MKS may have
incurred substantial expenses and devoted significant management time and
resources in seeking to complete proposed acquisitions that will not generate
benefits for it.

In addition, with future acquisitions, MKS could use substantial portions of its
available cash as all or a portion of the purchase price. MKS could also issue
additional securities as consideration for these acquisitions, which could cause
significant stockholder dilution. MKS' acquisitions of Compact Instrument,
Telvac, Spectra, D.I.P., ASTeX and On-Line and any future acquisitions may not
ultimately help MKS achieve its strategic goals and may pose other risks to MKS.
18

AN INABILITY TO CONVINCE SEMICONDUCTOR DEVICE MANUFACTURERS TO SPECIFY THE USE
OF MKS' PRODUCTS TO MKS' CUSTOMERS, WHO ARE SEMICONDUCTOR CAPITAL EQUIPMENT
MANUFACTURERS, WOULD WEAKEN MKS' COMPETITIVE POSITION.

The markets for MKS' products are highly competitive. Its competitive success
often depends upon factors outside of its control. For example, in some cases,
particularly with respect to mass flow controllers, semiconductor device
manufacturers may direct semiconductor capital equipment manufacturers to use a
specified supplier's product in their equipment. Accordingly, for such products,
MKS' success will depend in part on its ability to have semiconductor device
manufacturers specify that MKS' products be used at their semiconductor
fabrication facilities. In addition, MKS may encounter difficulties in changing
established relationships of competitors that already have a large installed
base of products within such semiconductor fabrication facilities.

IF MKS' PRODUCTS ARE NOT DESIGNED INTO SUCCESSIVE NEW GENERATIONS OF ITS
CUSTOMERS' PRODUCTS, MKS WILL LOSE SIGNIFICANT NET SALES DURING THE LIFESPAN OF
THOSE PRODUCTS.

New products designed by semiconductor capital equipment manufacturers typically
have a lifespan of five to ten years. MKS' success depends on its products being
designed into new generations of equipment for the semiconductor industry. MKS
must develop products that are technologically current so that they are
positioned to be chosen for use in each successive new generation of
semiconductor capital equipment. If MKS products are not chosen by its
customers, MKS' net sales may be reduced during the lifespan of its customers'
products. In addition, MKS must make a significant capital investment to develop
products for its customers well before its products are introduced and before it
can be sure that it will recover its capital investment through sales to the
customers in significant volume. MKS is thus also at risk during the development
phase that its products may fail to meet its customers' technical or cost
requirements and may be replaced by a competitive product or alternative
technology solution. If that happens, MKS may be unable to recover MKS'
development costs.

THE SEMICONDUCTOR INDUSTRY IS SUBJECT TO RAPID DEMAND SHIFTS WHICH ARE DIFFICULT
TO PREDICT. AS A RESULT, MKS' INABILITY TO EXPAND ITS MANUFACTURING CAPACITY IN
RESPONSE TO THESE RAPID SHIFTS MAY CAUSE A REDUCTION IN ITS MARKET SHARE.

MKS' ability to increase sales of certain products depends in part upon its
ability to expand its manufacturing capacity for such products in a timely
manner. If MKS is unable to expand its manufacturing capacity on a timely basis
or to manage such expansion effectively, its customers could implement its
competitors' products and, as a result, its market share could be reduced.
Because the semiconductor industry is subject to rapid demand shifts which are
difficult to foresee, MKS may not be able to increase capacity quickly enough to
respond to a rapid increase in demand in the semiconductor industry.
Additionally, capacity expansion could increase MKS' fixed operating expenses
and if sales levels do not increase to offset the additional expense levels
associated with any such expansion, its business, financial condition and
results of operations could be materially adversely affected.

SALES TO FOREIGN MARKETS CONSTITUTE A SUBSTANTIAL PORTION OF MKS' NET SALES;
THEREFORE, MKS NET SALES AND RESULTS OF OPERATIONS COULD BE ADVERSELY AFFECTED
BY DOWNTURNS IN ECONOMIC CONDITIONS IN COUNTRIES OUTSIDE OF THE UNITED STATES.

International sales, which include sales by MKS' foreign subsidiaries, but
exclude direct export sales (which were less than 10% of MKS' total net sales),
accounted for approximately 23% of net sales in 2000, 25% of net sales in 1999
and 21% of net sales in 1998.

MKS anticipates that international sales will continue to account for a
significant portion of MKS' net sales. In addition, certain of MKS' key domestic
customers derive a significant portion of their revenues from sales in
international markets. Therefore, MKS' sales and results of operations could be
adversely affected by economic slowdowns and other risks associated with
international sales.
19

UNFAVORABLE CURRENCY EXCHANGE RATE FLUCTUATIONS MAY LEAD TO LOWER GROSS MARGINS,
OR MAY CAUSE MKS TO RAISE PRICES WHICH COULD RESULT IN REDUCED SALES.

Currency exchange rate fluctuations could have an adverse effect on MKS' net
sales and results of operations and MKS could experience losses with respect to
its hedging activities. Unfavorable currency fluctuations could require MKS to
increase prices to foreign customers which could result in lower net sales by
MKS to such customers. Alternatively, if MKS does not adjust the prices for its
products in response to unfavorable currency fluctuations, its results of
operations could be adversely affected. In addition, sales made by MKS' foreign
subsidiaries are denominated in the currency of the country in which these
products are sold and the currency it receives in payment for such sales could
be less valuable at the time of receipt as a result of exchange rate
fluctuations. MKS enters into forward exchange contracts and local currency
purchased options to reduce currency exposure arising from intercompany sales of
inventory. However, MKS cannot be certain that its efforts will be adequate to
protect it against significant currency fluctuations or that such efforts will
not expose it to additional exchange rate risks.

COMPETITION FOR PERSONNEL IN THE SEMICONDUCTOR AND INDUSTRIAL MANUFACTURING
INDUSTRIES IS INTENSE.

MKS' success depends to a large extent upon the efforts and abilities of a
number of key employees and officers, particularly those with expertise in the
semiconductor manufacturing and similar industrial manufacturing industries. The
loss of key employees or officers could have a material adverse effect on MKS'
business, financial condition and results of operations. MKS believes that its
future success will depend in part on its ability to attract and retain highly
skilled technical, financial, managerial and marketing personnel. Competition
for such personnel is intense, and MKS cannot be certain that it will be
successful in attracting and retaining such personnel.

MKS' PROPRIETARY TECHNOLOGY IS IMPORTANT TO THE CONTINUED SUCCESS OF ITS
BUSINESS. MKS' FAILURE TO PROTECT THIS PROPRIETARY TECHNOLOGY MAY SIGNIFICANTLY
IMPAIR MKS' COMPETITIVE POSITION.

As of June 30, 2001, MKS owned 125 U.S. patents and 62 foreign patents and had
52 pending U.S. patent applications and 136 pending foreign patent applications.
Although MKS seeks to protect its intellectual property rights through patents,
copyrights, trade secrets and other measures, it cannot be certain that:

- - MKS will be able to protect its technology adequately;

- - competitors will not be able to develop similar technology independently;

- - any of MKS' pending patent applications will be issued;

- - intellectual property laws will protect MKS' intellectual property rights;
or

- - third parties will not assert that MKS' products infringe patent, copyright
or trade secrets of such parties.

PROTECTION OF MKS' INTELLECTUAL PROPERTY RIGHTS MAY RESULT IN COSTLY LITIGATION.

Litigation may be necessary in order to enforce MKS' patents, copyrights or
other intellectual property rights, to protect its trade secrets, to determine
the validity and scope of the proprietary rights of others or to defend against
claims of infringement. For example, on November 30, 2000, ASTeX brought suit in
federal district court in Delaware against Advanced Energy Industries, Inc. for
infringement of ASTeX's patent related to its Astron product. Such litigation
could result in substantial costs and diversion of resources and could have a
material adverse effect on MKS' business, financial condition and results of
operations.

THE MARKET PRICE OF MKS' COMMON STOCK HAS FLUCTUATED AND MAY CONTINUE TO
FLUCTUATE FOR REASONS OVER WHICH MKS HAS NO CONTROL.

The stock market has from time to time experienced, and is likely to continue to
experience, extreme price and volume fluctuations. Recently, prices of
securities of technology companies have been especially volatile and have often
fluctuated for reasons that are unrelated to the operating performance of the
companies. The market price of shares of MKS' common stock has fluctuated
greatly since its initial public offering and could continue to fluctuate due to
a variety of factors. In the past, companies that have experienced volatility in
the market price of their stock have been the objects of securities class action
litigation. If MKS were the object of securities class action litigation, it
could result in substantial costs and a diversion of MKS' management's attention
and resources.
20

MKS'S DEPENDENCE ON SOLE AND LIMITED SOURCE SUPPLIERS COULD AFFECT ITS ABILITY
TO MANUFACTURE PRODUCTS AND SYSTEMS.

MKS relies on sole and limited source suppliers for a few of its components and
subassemblies that are critical to the manufacturing of MKS's products. This
reliance involves several risks, including the following:

- - the potential inability to obtain an adequate supply of required
components;

- - reduced control over pricing and timing of delivery of components; and

- - the potential inability of its suppliers to develop technologically
advanced products to support MKS's growth and development of new systems.

MKS believes that in time MKS could obtain and qualify alternative sources for
most sole and limited source parts. Seeking alternative sources of the parts
could require MKS to redesign its systems, resulting in increased costs and
likely shipping delays. MKS may be unable to redesign its systems, which could
result in further costs and shipping delays. These increased costs would
decrease MKS' profit margins if it could not pass the costs to its customers.
Further, shipping delays could damage MKS' relationships with current and
potential customers and have a material adverse effect on MKS' business and
results of operations.

MKS IS SUBJECT TO GOVERNMENTAL REGULATIONS.

MKS is subject to federal, state, local and foreign regulations, including
environmental regulations and regulations relating to the design and operation
of MKS' power supply products. MKS must ensure that these systems meet certain
safety standards, many of which vary across the countries in which MKS' systems
are used.

For example, the European Union has published directives specifically relating
to power supplies. MKS must comply with these directives in order to ship MKS'
systems into countries that are members of the European Union. MKS believes it
is in compliance with current applicable regulations, directives and standards
and has obtained all necessary permits, approvals, and authorizations to conduct
MKS' business. However, compliance with future regulations, directives and
standards could require it to modify or redesign certain systems, make capital
expenditures or incur substantial costs. If MKS does not comply with current or
future regulations, directives and standards:

- - MKS could be subject to fines;

- - MKS' production could be suspended; or

- - MKS could be prohibited from offering particular systems in specified
markets.

ONE STOCKHOLDER, ALONG WITH MEMBERS OF HIS FAMILY, CONTINUES TO HAVE A
SUBSTANTIAL INTEREST IN MKS.

As of January 31, 2001, John R. Bertucci, chairman and chief executive officer
of MKS, and members of his family, in the aggregate, beneficially owned
approximately 41.4% of MKS' outstanding common stock. As a result, these
stockholders, acting together, are able to exert substantial influence over
actions of MKS.

SOME PROVISIONS OF MKS' AMENDED AND RESTATED ARTICLES OF ORGANIZATION, MKS'
BY-LAWS AND MASSACHUSETTS LAW COULD DISCOURAGE POTENTIAL ACQUISITION PROPOSALS
AND COULD DELAY OR PREVENT A CHANGE IN CONTROL OF MKS.

Anti-takeover provisions could diminish the opportunities for stockholders to
participate in tender offers, including tender offers at a price above the then
current market value of the common stock. Such provisions may also inhibit
increases in the market price of the common stock that could result from
takeover attempts. For example, while MKS has no present plans to issue any
preferred stock, MKS' board of directors, without further stockholder approval,
may issue preferred stock that could have the effect of delaying, deterring or
preventing a change in control of MKS. The issuance of preferred stock could
adversely affect the voting power of the holders of MKS' common stock, including
the loss of voting control to others. In addition, MKS' By-Laws provide for a
classified board of directors consisting of three classes. The classified board
could also have the effect of delaying, deterring or preventing a change in
control of MKS.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Information concerning market risk is contained in the Management's Discussion
and Analysis of Financial Condition and Results of Operations contained in the
Consolidated Supplemental Financial Statements for year ended December 31, 2000,
reflecting the merger of MKS Instruments, Inc. and ASTeX, which was filed with
the Securities and Exchange Commission in MKS's Current Report on Form 8-K on
April 20, 2001. MKS enters into local currency purchased options to reduce
currency exposure arising from intercompany sales of inventory. The potential
fair value loss for a hypothetical 10% adverse change in currency exchange rates
on MKS's local currency purchased options at June 30, 2001 would be
approximately $1.5 million. The potential loss was estimated by calculating the
fair value of the local currency purchased options at June 30, 2001 and
comparing that with those calculated using the hypothetical currency exchange
rates. There were no other material changes in MKS's exposure to market risk
from December 31, 2000.
