NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

1. BASIS OF PRESENTATION

The accompanying unaudited condensed consolidated financial statements have been
prepared in accordance with generally accepted accounting principles for interim
financial information and with the instructions to Form 10-Q and Article 10 of
Regulation S-X. Accordingly, they do not include all of the information and
footnotes required by generally accepted accounting principles for complete
financial statements. In the opinion of management, all adjustments (consisting
only of normal recurring accruals) considered necessary for a fair presentation
have been included. Operating results for the three-month period ended March 31,
2001 are not necessarily indicative of the results that may be expected for the
year ending December 31, 2001. For further information, refer to the
consolidated financial statements and footnotes thereto included in Novellus'
Annual Report on Form 10-K for the year ended December 31, 2000.

Certain amounts in the prior year balances have been reclassified to conform to
current year presentation.

On January 10, 2001, Novellus acquired GaSonics International Corporation
(GaSonics), a developer and supplier of photoresist and residue removal
technologies. At the completion of the merger, GaSonics became a wholly owned
subsidiary of Novellus. The GaSonics merger was accounted for as a
pooling-of-interests combination for financial reporting purposes in accordance
with generally accepted accounting principles and accordingly, Novellus'
historical consolidated financial statements presented have been restated to
include the financial position, results of operations, and cash flows of
GaSonics. The condensed consolidated financial statements for April 1, 2000
include results of Novellus' operations and balance sheet data on a December 31
fiscal year basis and GaSonics' results and balance sheet data on a September 30
fiscal year basis. In the transaction, Novellus acquired all outstanding shares
of GaSonics in a stock-for-stock merger, with all outstanding shares of GaSonics
capital stock converted into approximately 9,240,000 shares of Novellus common
stock. In addition, all outstanding options to purchase shares of GaSonics
capital stock were automatically converted into options to purchase
approximately 1,400,000 shares of Novellus common stock. There were no
transactions between GaSonics and Novellus prior to the combination.

The following information shows revenue and net income (loss) of the separate
companies for the period preceding the combination. Information related to
GaSonics is for the three months ended December 31, 1999 (in thousands).

NOVELLUS SYSTEMS, INC.
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

Revenue and net income of GaSonics for the three-month period ended December 31,
2000, which is excluded in the accompanying financial statements was $47.7
million and $0.862 million, respectively. Included in the accompanying condensed
consolidated statement of income for the three months ended March 31, 2001 are
merger-related expenses totaling $13.2 million consisting primarily of
professional fees, financial printing, and other related costs. Additionally,
these costs include charges related to vacating certain services agreements and
the write-off of redundant assets. Conforming adjustments consist of an
adjustment to the provision for income taxes for the realization of deferred tax
assets in fiscal 1999, rather than in fiscal 2000, adjustments related to
adoption of Staff Accounting Bulletin No. 101, "Revenue Recognition in Financial
Statements" as of October 1, 1999, and certain reclassifications to comply with
Novellus' accounting policies.

2. RECENT ACCOUNTING PRONOUNCEMENTS

Novellus changed its revenue recognition policy effective January 1, 2000, based
on guidance provided in SEC Staff Accounting Bulletin No. 101 (SAB 101),
"Revenue Recognition in Financial Statements." Novellus recognizes revenue when
persuasive evidence of an arrangement exists, delivery has occurred or services
have been rendered, the seller's price is fixed or determinable and
collectibility is reasonably assured. Certain of Novellus' product sales are
accounted for as multiple-element arrangements. If Novellus has met defined
customer acceptance experience levels with both the customer and the specific
type of equipment, Novellus recognizes equipment revenue upon shipment and
transfer of title, with the remainder when it becomes due (generally upon
acceptance). All other product sales with customer acceptance provisions are
recognized upon customer acceptance. Revenue related to spare part sales is
recognized on shipment. Revenue related to maintenance and service contracts is
recognized ratably over the duration of the contracts. Unearned maintenance and
service contract revenue is not significant and is included in accrued
liabilities.

In accordance with guidance provided in SAB 101, Novellus recorded a non-cash
charge of $89.8 million (after reduction for income taxes of $48.6 million), or
($0.65) per share in the first quarter of 2000, to reflect the cumulative effect
of the accounting change as of the beginning of the fiscal year. During the
quarter ended April 1, 2000, Novellus recognized $55.0 million in revenue that
is included in the cumulative effect adjustment as of January 1, 2000. The
effect of that revenue was to increase income by $22.9 million, net of tax.
There was no amount of revenue recorded in the quarter ended March 31, 2001 that
was included in the cumulative effect adjustment as of January 1, 2000.

On January 1, 2001, Novellus adopted Statement of Financial Accounting Standards
No. 133, "Accounting for Derivative Instruments and Hedging Activities" (SFAS
133), which establishes accounting and reporting standards for derivative
instruments, including forward exchange contracts, and hedging activities. SFAS
133 requires Novellus to recognize all derivatives on the balance sheet at fair
value. Derivatives that are not hedges must be adjusted to fair value through
income. If the derivative is a hedge, depending on the nature of the hedge,
changes in the fair value of the derivative are either offset against the change
in fair value of assets, liabilities, or firm commitments through earnings (fair
value hedges) or recognized in other comprehensive income until the hedged item
is recognized in earnings (cash flow hedges). The ineffective portion of a
derivative's change in fair value is immediately recognized in earnings. The
adoption of SFAS 133 did not have a material impact on the Company's
consolidated financial position or operating results.

that approximate the banks' prime rates. These facilities are available to
Novellus' Japanese subsidiaries, Nippon Novellus Systems K.K. and GaSonics

6. LONG-TERM DEBT

In June 1997, Novellus entered into a five year, $125.0 million, Senior Credit
Facility structured as an unsecured revolving credit line. The credit line
expires in June 2002. Borrowings, at the option of Novellus, bear interest at
either a base rate plus a margin or the London Interbank Offering Rate ("LIBOR")
plus a margin for interest periods of one to six months. There were no
borrowings outstanding under the Senior Credit Facility at March 31, 2001.

The Senior Credit Facility contains certain restrictive financial covenants. At
March 31, 2001, Novellus was in compliance with these covenants.

7. COMMITMENTS

Novellus has lease agreements on thirteen properties. The agreements are for
five years each with the option to extend for three one-year renewal periods at
an interest rate that approximates the LIBOR. The lease terms expire at various
dates beginning on June 2002 through September 2003. At current interest rates,
the annual lease payments total approximately $15.8 million. During the terms of
the leases, Novellus may elect to purchase the properties for an amount that
approximates the lessor's cost of the property and any current rent due and
payable. These leases contain certain restrictive financial covenants. At March
31, 2001, Novellus was in compliance with these covenants.

On April 13, 2001 and April 18, 2001, Novellus entered into two additional lease
agreements. These agreements refinanced certain properties noted above and added
one additional property. The agreements are for five years each with the option
to extend for three one-year renewal periods at an interest rate that
approximates the LIBOR. The lease terms expire in April 2006. At current
interest rates, the annual lease payments on these two agreements incrementally
increase the current annual lease payments by $12.4 million once construction is
completed. During the terms of the leases, Novellus may elect to purchase the
properties for an amount that approximates the lessor's cost of the property and
any current rent due and payable.

ITEM 2:

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS

RESULTS OF OPERATIONS

On January 10, 2001, Novellus acquired GaSonics International Corporation
(GaSonics), a developer and supplier of photoresist and residue removal
technologies. At the completion of the merger, GaSonics became a wholly owned
subsidiary of Novellus. The GaSonics merger was accounted for as a
pooling-of-interests combination for financial reporting purposes in accordance
with generally accepted accounting principles and accordingly, Novellus'
historical consolidated financial statements presented in future reports will be
restated to include the accounts and results of operations of GaSonics. In the
transaction, Novellus acquired all outstanding shares of GaSonics in a
stock-for-stock merger, with all outstanding shares of GaSonics capital stock
converted into approximately 9,240,000 shares of Novellus common stock. In
addition, all outstanding options to purchase shares of GaSonics capital stock
were automatically converted into options to purchase approximately 1,400,000
shares of Novellus common stock. There were no transactions between GaSonics and
Novellus prior to the combination and certain adjustments were necessary to
conform GaSonics' accounting policies to Novellus' accounting policies.

Net sales for the three months ended March 31, 2001 were $458.7 million,
compared with $220.0 million for the comparable year-ago quarter, and $442.7
million for the immediately preceding quarter. The increase in net sales over
the comparable year-ago period is due to the increase in net sales across all
product lines. The increase in net sales from the immediately preceding quarter
is primarily due to the recognition of prior quarter shipments in accordance
with SAB 101, as there was a decrease in shipments as a result of current market
conditions.

International net sales (including export sales) for the three months ended
March 31, 2001, were 56% of total net sales, which compares to the comparable
year-ago period of 73% and 57% for the immediately preceding quarter. The
decreases primarily relate to decreases in net sales in the Pacific Rim region,
which includes China, Malaysia, and Taiwan, offset by modest increases in net
sales in the U.S.

Gross profit as a percentage of net sales for the three months ended March 31,
2001 was 55.6%, compared with 57.2% for the immediately preceding quarter and
53.3% for the comparable year-ago period. The increase over the comparable
year-ago period is due to successful cost reduction efforts and improved
absorption of fixed overhead costs. The decrease from the immediately preceding
quarter is due to reduced absorption of fixed overhead as the market conditions
weakened in the industry. Novellus anticipates continued pressure on gross
profit as a percentage of sales as a result of an anticipated decline in revenue
levels in the second and third quarters of 2001.

Selling, general and administrative (SG&A) expenses for the three months ended
March 31, 2001 were $68.9 million compared with $44.1 million in the comparable
year-ago quarter, and $59.8 million from the immediately preceding quarter. SG&A
expenses as a percentage of net sales for the three months ended March 31, 2001
were 15.0% compared with 20.1% for the comparable year-ago quarter, and 13.5%
for the immediately preceding quarter. The increase in SG&A expenses in

11
12

absolute dollars and as a percentage of revenues from the immediately preceding
quarter is due to higher selling costs and the effect of combining the SG&A
organizations of GaSonics with Novellus. The decrease in SG&A expenses as a
percentage of revenue from the comparable year-ago period is due to Novellus'
efforts to control costs as a percentage of revenues.

Research and development (R&D) expenses for the three months ended March 31,
2001 were $70.5 million compared with $44.4 million for the comparable year-ago
quarter, and $66.7 million for the immediately preceding quarter. R&D expenses
as a percentage of net sales for the three months ended March 31, 2001 were
15.4% compared with 20.2% for the comparable year-ago period, and 15.1% for the
immediately preceding quarter. The increase in R&D expenses over the comparable
year-ago period and the immediately preceding quarter in absolute dollars is
primarily due to higher headcount, project materials, and facilities costs
reflecting Novellus' continuing commitment to invest in key product development
projects.

Merger costs related to the acquisition of GaSonics were $13.2 million. These
costs included professional fees, financial printing, and other related costs.
Additionally, these costs include charges related to vacating certain services
agreements and the write-off of redundant assets.

Net interest income for the three months ended March 31, 2001 was $16.6 million
compared with $5.8 million for the comparable year-ago quarter, and $18.6
million recorded in the immediately preceding quarter. The increase in net
interest income over the comparable year-ago quarter is primarily due to
increased cash and short-term investment balances as a result of Novellus'
secondary public offering of approximately 9.0 million shares during the second
quarter of 2000 which resulted in net proceeds to Novellus of $526.3 million.
The decrease in net interest income compared to the immediately preceding
quarter is due to lower interest rates earned on Novellus' cash and short term
investment balances.

Novellus' effective tax rate for the three months ended March 31, 2001 was 31%,
which is the same as the comparable year-ago quarter and the immediately
preceding quarter, excluding a $6.0 million charge for in-process R&D.

Net income for the three months ended March 31, 2001 was $82.1 million or $0.55
per share compared with $23.8 million or $0.17 per share (excluding a cumulative
effect of a change in accounting principle of $89.8 million, or $0.65 per share)
for the comparable year-ago period, and $93.9 million or $0.64 per share for
the immediately preceding quarter.

Net income for the first quarter, excluding $13.2 million in one-time charges
taken in connection with the acquisition of GaSonics, was $91.2 million or $0.62
per share. This represents a modest decrease from fourth quarter net income,
excluding a $6.0 million charge for in-process R&D, of $99.9 million or $0.68
per share, but a substantial increase over the comparable quarter in 2000 in
which Novellus earned $23.8 million or $0.17 per share, excluding the cumulative
effect of a change in accounting principle of $89.8 million or $0.65 per share.

The number of shares used in the per share calculations for the three months
ended March 31, 2001 was 148.1 million compared with 137.1 million for the
comparable year-ago period and 146.1 million for the immediately preceding
period. The increase in shares used for both the comparable year-ago period and
the immediate preceding quarter is due to an increased number of common stock
equivalents as a result of an increased number of stock options.

type of equipment, Novellus recognizes equipment revenue upon shipment and
transfer of title, with the remainder when it becomes due (generally upon
acceptance). All other product sales with customer acceptance provisions are
recognized upon customer acceptance. Revenue related to spare part sales is
recognized on shipment. Revenue related to maintenance and service contracts is
recognized ratably over the duration of the contracts. Unearned maintenance and
service contract revenue is not significant and is included in accrued
liabilities.

On January 1, 2001, Novellus adopted Statement of Financial Accounting Standards
No. 133, "Accounting for Derivative Instruments and Hedging Activities" (SFAS
133), as discussed in Note 2, "Recent Accounting Pronouncements" in the Notes to
Condensed Consolidated Financial Statements. Novellus enters into forward
foreign exchange contracts primarily to hedge against the short-term impact of
foreign currency fluctuations of intercompany accounts payable denominated in
U.S. dollars recorded by Novellus' Japanese subsidiary, Nippon Novellus Systems
K.K. Novellus also enters into forward foreign exchange contracts to buy and
sell foreign currencies as economic hedges of the parent's intercompany balances
denominated in a currency other than the U.S. dollar. The forward foreign
exchange contracts are marked to market each period with net foreign currency
gains and losses immediately recognized in earnings. The adoption of SFAS 133
did not have a significant impact on Novellus' consolidated financial position
or operating results.

EURO CONVERSION

On January 1, 1999, several member countries of the European Union established
fixed conversion rates between their existing sovereign currencies and adopted
the Euro as their new common legal currency. As of that date, the Euro traded on
currency exchanges and the legacy currencies remain legal tender in the
participating countries for a transition period between January 1, 1999 and
January 1, 2002. During the transition period, non-cash payments can be made in
the Euro, and parties can elect to pay for goods and services and transact
business using either the Euro or legacy currency. Between January 1, 1999 and
January 1, 2002 the participating countries will introduce Euro notes and coins
and withdraw all legacy currencies so that they will no longer be available. The
Euro conversion may affect cross-border competition by creating cross-border
transparency. Novellus is assessing its pricing/marketing strategy in order to
ensure that it remains competitive in a broader European market. Novellus is
also assessing its information technology systems to allow for transactions to
take place in both legacy currencies and the Euro and the eventual elimination
of the legacy currencies, and reviewing whether certain existing contracts will
need to be modified. Novellus' currency risk for operations in participating
countries may be reduced as the legacy currencies are converted to the Euro.

LIQUIDITY AND CAPITAL RESOURCES

Novellus has historically financed its operations and capital resources through
cash flow from operations, sales of equity securities and borrowings. Novellus'
primary sources of funds at March 31, 2001 consisted of $1,200.0 million of
cash, cash equivalents and short-term investments. This amount represents a
decrease of $19.7 million from the December 31, 2000 balance of $1,219.7
million. During the second quarter of 2000, Novellus completed a secondary
public offering of approximately 9.0 million shares of common stock that
resulted in net proceeds to Novellus of approximately $526.3 million.

During the second quarter of 1997, Novellus entered into a five year $125.0
million Senior Credit Facility structured as an unsecured revolving credit line.
The borrowings, at the option of Novellus, bear interest at either a base rate
plus a margin or the LIBOR plus a margin for interest periods of one to six
months. At March 31, 2001, there were no outstanding borrowings under this
facility. The Senior Credit Facility requires Novellus to be in compliance with
certain financial covenants. At March 31, 2001, Novellus was in compliance with
these financial covenants.

In addition, at March 31, 2001, there was $38.6 million available under bank
lines of credit that expire at various dates through April 2002. At March 31,
2001, approximately $28.5 million was outstanding under these bank lines of
credit, which bear interest at the banks' prime lending rates or offshore
reference rates.

During the three months ended March 31, 2001, Novellus' cash and cash
equivalents increased $151.7 million to $741.1 million from $589.4 million at
December 31, 2001. Net cash used in operating activities during the first three
months of 2001 was $1.3 million primarily due to net income of $82.1 million and
a decrease in accounts receivable of $63.1 million, offset by decreases in
accounts payable, income taxes payable, and deferred profit of $31.0 million,
$26.1 million, and $60.5 million, respectively, and an increase in inventories
of $33.0 million.

Net cash flows provided by investing activities were $136.3 million during the
first three months of 2001. During this period, Novellus had net sales of $176.7
million of available-for-sale securities. These amounts were partially offset by
capital expenditures and a change in long-term other assets of $32.8 million and
$7.6 million, respectively during the period.

Novellus expects investments in property and equipment in the current fiscal
year to approximate $87.5 million of which $16.0 million had been incurred as of
March 31, 2001. Novellus intends to finance these investments from existing cash
balances and cash flows from operations.

During the first three months of 2001, net cash provided by financing activities
increased $16.6 million primarily due to $9.7 million of proceeds from the
issuance of common stock related to the exercise of employee stock options. In
addition, Novellus received proceeds of $6.9 million under its bank lines of
credit.

Novellus believes that its current cash position and cash generated through
operations, if any, will be sufficient to meet Novellus' needs through at least
the next twelve months.

PART II: OTHER INFORMATION

ITEM 1: LEGAL PROCEEDINGS

APPLIED LITIGATION

On July 7, 1997, prior to the consummation of the purchase of TFS from Varian,
Applied Materials, Inc. ("Applied") filed a complaint (the "Applied Complaint")
against Varian in the United States District Court for the Northern District of
California San Jose Division, Civil Action No. C-97-20523 RMW, alleging, among
other things, infringement by Varian (including the making, using, selling
and/or offering for sale of certain products and systems made by TFS) of United
States Patent Nos. 5,171,412, 5,186,718, 5,496,455 and 5,540,821 (the "Applied
Patents"), which patents are owned by Applied.

Immediately after consummation of the TFS purchase, Novellus filed a complaint
(the "Novellus Complaint") against Applied in the same Court, Civil Action No.
C-97-20551 RMW, alleging infringement by Applied (including the making, using,
selling and/or offering for sale of certain products and systems) of United
States Patent Nos. 5,314,597, 5,330,628, and 5,635,036 (the "Novellus Patents"),
which patents Novellus acquired from Varian in the TFS purchase. In the Novellus
Complaint, Novellus also alleged that it is entitled to declarations from
Applied that Novellus does not infringe the Applied Patents and/or that the
Applied Patents are invalid and/or unenforceable. Applied has filed
counterclaims alleging that Novellus infringes the Applied Patents.

Also after consummation of the TFS purchase, but some time after Novellus filed
the Novellus Complaint, Applied amended the Applied Complaint to add Novellus as
a defendant. Novellus has requested that the Court dismiss Novellus as a
defendant in Applied's lawsuit against Varian. The Court has not yet required
Novellus to file an answer to the Applied Complaint.

In addition to a request for a permanent injunction against further
infringement, the Applied Complaint and Applied's counterclaims to Novellus
Complaint include requests for damages for alleged prior infringement and treble
damages for alleged "willful" infringement. In connection with the consummation
of the TFS purchase, Varian agreed, under certain circumstances, to reimburse
Novellus for certain of its legal and other expenses in connection with the
defense and prosecution of this litigation, and to indemnify Novellus for a
portion of any losses incurred by Novellus arising from this litigation
(including losses resulting from a permanent injunction). Novellus and Varian
believe that there are meritorious defenses to Applied's allegations, including
among other things, that Novellus' operations (including TFS products and
systems) do not infringe the Applied Patents and/or that the Applied Patents are
invalid and/or unenforceable. However, the resolution of intellectual property
disputes is often fact intensive and, therefore, inherently uncertain. Although
Novellus believes that the ultimate outcome of the dispute with Applied will not
have a material adverse effect on Novellus' business or results of operations
(taking into account both the defenses available to Novellus and Varian's
reimbursement and indemnity obligations), there can be no assurances that
Applied will not ultimately prevail in this dispute and that, in such an event,
Varian's reimbursement and indemnity obligations will not be sufficient to fully
reimburse Novellus for its losses. If Applied were to prevail in this dispute,
it could have a material adverse effect on Novellus' business or results of
operations.

The Novellus Complaint against Applied also includes requests for damages for
prior infringement and treble damages for "willful" infringement, in addition to
a request for a permanent injunction for further infringement. Although Novellus
believes that it will prevail against Applied, there can be no assurances that
Novellus will prevail in its litigation against Applied. If Applied were to

16
17

prevail against the Novellus Complaint, it could have a material adverse effect
on Novellus' business, financial condition or results of operations.

On July 13, 1999, in the Novellus lawsuit against Applied where Novellus has
alleged that Applied infringes Novellus patents, the Court ruled on the
interpretation of the claims of the Novellus Patents. On September 20, 1999, in
the Applied lawsuit against Varian and Novellus, where Applied has alleged that
Varian and Novellus infringe Applied patents, the Court ruled on the
interpretation of the claims of the Applied patents.

On September 10, 1999, Novellus filed a motion for summary judgment that claims
1, 2 and 8 of its U.S. Patent No. 5,314,597 are not invalid over the prior art
asserted against it by Applied. On September 29, 1999, Applied filed a
counter-motion for summary judgment that these claims are invalid based on the
on-sale bar. On December 7, 1999, the Court entered an order granting Novellus'
motion and denying Applied's motion.

On November 4, 1999, Applied moved for leave of Court to amend its prior art
chart with respect to Novellus' U.S. Patent No. 5,314,597. On February 15, 2000,
the Court granted Applied's motion. On October 4, 2000, the Court entered an
order denying Novellus' motion for reconsideration of this order.

On December 17, 1999, Novellus and Varian moved for summary judgment that
certain claims of Applied's U.S. Patent No. 5,171,412 were invalid as
anticipated or obvious over the prior art. On March 16, 2000, the Court granted
this motion in part, and deferred ruling in part.

On December 23, 1999, Novellus moved for summary judgment that its U.S. Patent
No. 5,635,036 is not invalid as obvious over the prior art. On March 20, 2000,
the Court denied Novellus' motion without prejudice.

On January 14, 2000, Applied withdrew its U.S. Patent No. 5,496,455 from the
lawsuits against Novellus and Varian.

On February 4, 2000, Applied filed a motion for summary judgment that claims 10,
11 and 13 of Novellus' U.S. Patent No. 5,314,597 are invalid over the prior art.
On March 10, 2000, Novellus filed an opposition and cross-moved for leave to
amend its claim chart to withdraw these claims. On April 5, 2000, the Court
issued an order denying Applied's motion as moot and granting Novellus' motion.

On March 31, 2000, Novellus filed a renewed motion for partial summary judgment
that its U.S. Patent No. 5,635,036 is not invalid as obvious over the prior art.
On January 3, 2001, the Court entered an order in response to this motion
tentatively amending certain claim constructions and requesting additional
briefing.

On March 16, 2000, the Court granted Varian's motion for summary judgement that
claims 14 & 18 of Applied's U.S. Patent No 5,171,412 are invalid. In the same
order, the Court gave Applied 3 months to conduct discovery concerning an issue
relating to Varian's motion for summary judgement that claim 21 is invalid.
After that discovery period, Varian may renew its motion to invalidate claim 21.

On July 28, 2000, Applied filed a motion for summary judgment of
non-infringement of Novellus' U.S. Patent No. 5,330,628. On October 20, 2000,
Novellus filed a non-opposition to that motion, pending appeal of the Court's
claim construction. Novellus also cross-moved for the Court to dismiss Applied's
allegations that the '628 patent was invalid or unenforceable. On November 20,
2000, the Court entered an order granting both motions.

17
18

On May 12, 2000, Novellus and Varian moved for summary judgment that the Inova
and MB2 do not infringe Applied's U.S. Patent No. 5,186,718. On August 8, 2000,
the Court granted this motion with respect to the Inova. Novellus' motion that
the MB2 does not infringe the '718 patent is currently off calendar pending
completion of discovery.

On August 18, 2000, Applied filed a motion for partial summary judgment that
certain of its products did not infringe Novellus' U.S. Patent No. 5,635,036. On
October 24, the Court entered an order denying Applied's motion. The Court, in
the same order, also allowed Novellus to withdraw its assertion that certain
Applied products infringed certain claims of its U.S. Patent No. 5,314,597.

On or about September 25, 2000, Varian and Applied executed a "License and
Settlement Agreement." On September 29, 2000, Varian and Applied filed a
Stipulated Dismissal with Prejudice with the Court that reciprocally dismisses
all causes of action that Varian and Applied had asserted or could have asserted
against one another in the litigation. In addition, Applied has stated, in its
agreement with Varian, that it will release Novellus from all claims that arose
out of or relate to the litigation that relate to any infringement alleged with
respect to the Inova, in the form as it existed as of the effective date of
Novellus' purchase of Varian's TFS division. The Stipulated Dismissal, however,
expressly excludes Novellus from the scope of any release.

On October 6, 2000, Applied filed a motion for summary judgment of
noninfringement of Novellus' U.S. Patent No. 5,314,597. On November 13, 2000,
Novellus filed an opposition to that motion, and cross-moved for summary
judgment of infringement as to claims 1 and 8 of the '597 patent. These motions
were orally argued on January 5, 2001 and are presently under submission.

On November 22, 2000, Applied filed a second motion for summary judgment that
its accused products do not infringe Novellus' U.S. Patent No. 5,635,036. This
motion was orally argued on January 19, 2001 and is presently under submission.

SEMITOOL LITIGATION

On August 10, 1998, Semitool sued Novellus for patent infringement in the United
States District Court for the Northern District of California. Semitool alleges
that Novellus' SABRE(TM) copper deposition system infringes two Semitool
patents, U.S. Patent No. 5,222,310, issued June 29, 1993, entitled "Single Wafer
Processor with a Frame," and U.S. Patent No. 5,377,708, issued January 3, 1995,
entitled "Multi-Station Semiconductor Processor with Volatilization." Semitool
seeks an injunction against Novellus' manufacture and sale of SABRE(TM) systems,
and seeks damages for past infringement. Semitool also seeks trebled damages for
alleged willful infringement. Semitool also seeks its attorneys' fees and costs,
and interest on any judgement.

On September 24, 1999, the Court ruled on the interpretation of the claims of
the Semitool patents. On December 18, 1999, Novellus filed a motion for summary
judgement of non-infringement.

On March 17, 2000, the Court granted Novellus' motion for summary judgement of
non-infringement. The Court ruled that Novellus' SABRE and SABRE xT systems do
not infringe on the two patents asserted by Semitool.

On May 15, 2000, Semitool filed a notice of appeal, appealing the Court's
judgement to the United States Court of Appeals for the Federal Circuit.
Semitool filed its opening brief on July 24, 2000. Novellus filed its opening
brief on October 3, 2000. Semitool filed its reply brief on November 3, 2000.
Oral argument took place on April 2, 2001.

18
19

Although Novellus believes that the Court's order granting summary judgment of
non-infringement was correct, and that Novellus will prevail on appeal, there
can be no assurances that Novellus will prevail in its litigation against
Semitool. If the Court's order is reversed on appeal, and if Semitool were to
prevail against Novellus following the appeal Complaint, it could have a
material adverse effect on Novellus' business, financial condition or results of
operations.

PLASMA PHYSICS LITIGATION

On December 28, 1999, Plasma Physics Corporation and Solar Physics Corporation
(collectively, "Plasma Physics") filed a patent infringement lawsuit against
many of Novellus' Japanese and Korean customers. The suit was entitled Plasma
Physics and Solar Physics v. Fujitsu et al., Civil Action No. 99-8593, and was
pending in the United States District Court for the Eastern District of New
York. On July 24, 2000, the Court ordered Plasma Physics to re-file separate
complaints against the Japanese and Korean defendants, whereupon, Civil Action
No. 99-8593 would be dismissed without prejudice. In accordance with the Court's
order, Plasma Physics has since re-filed separate complaints against the
Japanese and Korean defendants in the United States District Court for the
Eastern District of New York. Many of the defendants have notified Novellus that
they believe that Novellus has indemnification obligations and liability for the
lawsuits.

Plasma Physics has asserted U.S. Patent Nos. 4,226,897; 5,470,784, and 5,543,634
(the "'897, '784, and '634 patents," respectively). Plasma Physics seeks an
injunction against the defendants' alleged infringement of the '784 and '634
patents (the '897 patent has expired). Plasma Physics also seeks trebled damages
for alleged willful infringement. Plasma Physics further seeks its attorney's
fees and costs, and interest on any judgement.

On June 1, 2000, Novellus filed a declaratory relief action against Plasma
Physics and Solar Physics requesting a judgement of non-infringement,
invalidity, and unenforceability with respect to the '897 and '784 patents. The
suit is entitled Novellus v. Plasma Physics and Solar Physics, Civil Action No.
00-3146, and is pending in the United States District Court for the Eastern
District of New York. On June 30, 2000, Plasma Physics filed a motion to dismiss
Novellus' complaint for a lack of subject matter jurisdiction. Plasma Physics'
motion to dismiss Novellus' complaint was denied without prejudice on July 24,
2000. On July 31, 2000, Plasma Physics filed an Answer and Conditional
Counterclaim. Plasma Physics denies that the '897 and '784 patents are invalid
and unenforceable. Plasma Physics further denies that the '784 patent is not
infringed by Novellus. Plasma Physics also asserted a conditional counterclaim
against Novellus, alleging that Novellus' PECVD processing systems infringe the
'784 patent.

Novellus believes that there are meritorious defenses to Plasma Physics'
allegations, including among other things, that the defendants' use of Novellus'
equipment does not infringe the Plasma Physics patents and/or that the Plasma
Physics patents are invalid and/or unenforceable. But the resolution of
intellectual property disputes is often fact intensive and, like most other
litigation matters, inherently uncertain. Although Novellus believes that the
ultimate outcome of the dispute with Plasma Physics will not have a material
adverse effect on Novellus' business, financial condition, or result of
operations (taking into account the defenses available to it), there can be no
assurances that Plasma Physics will not ultimately prevail in this dispute and
that Novellus will not have any indemnity obligations or liability. If Plasma
Physics were to prevail in the dispute, it could have a material adverse effect
on Novellus' business, financial condition or results of operations.
