    multiplied by $91.09 (the average of the high and low prices of Etec
    common stock on the Nasdaq National Market on February 4, 2000),

                     QUESTIONS AND ANSWERS ABOUT THE MERGER

Q: Why are the two companies proposing to merge?

   A: Applied Materials and Etec are proposing to merge because we believe the
resulting combination will create a stronger, more competitive company capable
of achieving greater financial strength, operational efficiencies, technology
development, earning power and growth potential than either company would have
on its own.

Q: What will I, as an Etec stockholder, receive in the merger?

   A: As a result of the merger, you will receive 0.649 of a share of Applied
Materials common stock for each share of Etec common stock that you own. As no
fractional shares will be issued, you will receive a cash payment for any
fractional share. For example, if you own 100 shares of Etec common stock, you
will receive 64 shares of Applied Materials common stock in exchange for your
Etec shares and a cash payment equal to the value of 0.9 of a share of Applied
Materials common stock. The number of shares of Applied Materials common stock
to be issued for each share of Etec common stock is fixed and will not be
adjusted based upon changes in the value of Etec or Applied Materials common
stock. As a result, the value of the Applied Materials shares you will receive
in the merger will not be known before the merger, and will go up or down as
the market price of Applied Materials common stock goes up or down. We
encourage you to obtain current market quotations of Etec and Applied Materials
common stock.

Q: What do I need to do now?

   A: We urge you to read this proxy statement/prospectus carefully, including
its annexes, and to consider how the merger affects you. Then mail your signed
proxy card in the enclosed return envelope as soon as possible so that your
shares can be voted at the special meeting of Etec stockholders.

Q: What happens if I do not return my proxy card?

   A: The failure to return your proxy card will have the same effect as voting
against the proposal to approve the merger agreement.

Q: May I vote in person?

   A: Yes. You may attend the special meeting of Etec stockholders and vote
your shares in person, rather than signing and returning your proxy card or
even after you have signed your proxy card provided you properly revoke your
proxy (see below).

Q:  May I change my vote after I have mailed my signed proxy card?

   A: Yes. You may change your vote at any time before your proxy card is voted
at the special meeting. You can do this in one of three ways. First, you can
send a written notice stating that you would like to revoke your proxy. Second,
you can complete and submit a new proxy card with a later date. Third, you can
send a written notice dated later than the date of your proxy to the Secretary
of Etec stating that you would like to revoke your proxy and then attend the
meeting and vote in person. Please note that your attendance alone will not
revoke your proxy. If you have instructed a broker to vote your shares, you
must follow directions received from your broker to change those instructions.

Q: If my shares are held in "street name" by my broker, will my broker vote my
shares for me?

   A: Your broker will not be able to vote your shares without instructions
from you. You should instruct your broker to vote your shares, following the
procedure provided by your broker.

common stock.

   A: No, Etec stockholders will not be entitled to dissenters' rights in
connection with the merger.

THE COMPANIES (Page 28)

   APPLIED MATERIALS, INC.
   3050 Bowers Avenue
   Santa Clara, California 95054
   (408) 727-5555

   Organized in 1967, Applied Materials develops, manufactures, markets and
services semiconductor wafer fabrication equipment and related spare parts for
the worldwide semiconductor industry. Applied Materials' customers include
semiconductor wafer manufacturers and semiconductor "chip" or integrated
circuit ("IC") manufacturers, who either use the ICs they manufacture in their
own products or sell them to other companies. These ICs are the key components
in most advanced electronic products such as computers, telecommunication
devices, automotive engine management systems and electronic games.

   ETEC SYSTEMS, INC.
   26460 Corporate Avenue
   Hayward, California 94545
   (510) 783-9210

   Etec is a leader in patterning solutions for the semiconductor and
electronics industries. Etec designs, develops, manufactures and markets
electron and laser beam systems that produce high-precision masks, which are
used to print circuit patterns onto semiconductor wafers. Etec was incorporated
in 1989 under the laws of Nevada to effect a leveraged buyout in 1990 of the
former Electron Beam Technology Division of The Perkin-Elmer Corporation, which
was itself the continuation of a business commenced in 1970.

THE MERGER (Page 33)

   Under the merger agreement, a wholly-owned subsidiary of Applied Materials
will merge with and into Etec. After this merger, Applied Materials will own
all of the outstanding stock of Etec. This will make Etec a wholly-owned
subsidiary of Applied Materials. Stockholders of Etec will receive common stock
of Applied Materials in the merger in exchange for their Etec common stock.

MERGER CONSIDERATION; FIXED EXCHANGE RATIO (Page 49)

   You will receive 0.649 of a share of Applied Materials common stock in
exchange for each share of Etec common stock you own. The actual number of
shares you will receive in the merger will be 0.649 multiplied by the number of
shares of Etec common stock that you own at the effective time of the merger,
except that you will receive cash for any fractional share.

   The exchange ratio is fixed. Regardless of fluctuations in the market prices
of Applied Materials' or Etec's common stock, the exchange ratio will not
change between now and the date that the merger is completed.

COMPARATIVE PER SHARE MARKET PRICE INFORMATION (Page 8)

   Etec and Applied Materials common stock are both listed on the Nasdaq
National Market under the symbols "ETEC" and "AMAT", respectively. On January
12, 2000, the last full trading day prior to the public announcement of the
proposed merger, Etec common stock closed at $49.88, and Applied Materials
common stock closed at $127.06. On February 7, 2000, Etec common stock closed
at $94.38, and Applied Materials common stock closed at $153.63.

   The stock prices of both Applied Materials and Etec can fluctuate broadly
even over short periods of time. It is impossible to predict the actual price
of Applied Materials or Etec common stock prior to the effective time of the
merger or at any other time.

TAX MATTERS (Page 46)

   The exchange of shares of Etec common stock for shares of Applied Materials
common stock in the merger is intended to be tax-free to Etec stockholders for
federal income tax purposes. Any cash received for any fractional share,
however, will result in the recognition of gain or loss as if you sold your
fractional share. Your tax basis in the total number of shares of Applied
Materials common stock that you receive in the merger will equal your current
tax basis in the total number of shares of Etec common stock that you own
(reduced by the basis allocable to any fractional share interest for which you
receive cash).

   TAX MATTERS CAN BE COMPLICATED, AND THE TAX CONSEQUENCES OF THE MERGER TO
YOU WILL DEPEND ON THE FACTS OF YOUR OWN SITUATION. YOU SHOULD CONSULT YOUR OWN
TAX ADVISOR TO FULLY UNDERSTAND THE TAX CONSEQUENCES OF THE MERGER TO YOU.

REASONS FOR THE MERGER

   Applied Materials (Page 37). The Applied Materials board of directors
approved the merger based on a number of factors, including the following:

  . the ability of the combined company to offer complementary product lines
    and improve product offerings;

  . the ability of the two companies to combine their technological resources
    to develop new products with increased functionality and bring them to
    market faster;

                                       4
<PAGE>


  . the strategic benefits of the ability of the combined company to commit
    greater resources to both current and emerging product development
    efforts and fund the future growth of its business;

  . entry into a new strategic market segment for Applied Materials, with the
    potential for above average growth through an established market leader;
    and

  . Etec's critical technologies and significant technical, engineering,
    management and sales expertise, which is in high demand and short supply.

   Etec (Page 38). The Etec board of directors believes that the merger could
result in a number of benefits to Etec and its stockholders, including, among
other benefits, the following:

  . providing Etec stockholders with shares of Applied Materials common stock
    in a tax-free exchange at a substantial premium over the prevailing
    market price for Etec common stock immediately prior to the announcement
    of the merger;

  . mitigating the risk of large changes in Etec's stock price due to
    significant variations in Etec's shipments from quarter to quarter;

  . dampening the magnitude of swings in operating results based on different
    demand cycles for the two companies' products;

  . the availability of greater resources for product distribution and
    service; and


  . the ability of the combined company to offer complementary product lines,
    which presents the opportunity to increase the breadth of products
    offered.

RECOMMENDATION TO ETEC STOCKHOLDERS

   The Etec board of directors believes that the merger is advisable and fair
to you and in your best interests. The Etec board of directors unanimously
recommends that you vote "FOR" approval of the merger agreement.

OPINION OF ETEC'S FINANCIAL ADVISOR (Page 41)

   In deciding to approve the merger, one of the factors that the Etec board of
directors considered was the opinion of its financial advisor, Goldman, Sachs &
Co., that, as of January 12, 2000 and subject to the considerations set forth
in the opinion, the exchange ratio pursuant to the merger agreement was fair
from a financial point of view to the holders of shares of Etec common stock.
Goldman Sachs' opinion was provided for the information and assistance of the
board of directors of Etec in connection with its consideration of the
transaction contemplated by the merger agreement and its opinion does not
constitute a recommendation as to how any holder of Etec shares of common stock
should vote with respect to the merger agreement. The full text of the Goldman
Sachs opinion which sets forth assumptions made, matters considered and
limitations on the review undertaken by Goldman Sachs in connection with the
opinion is attached as Annex B to this proxy statement/prospectus. ETEC URGES
YOU TO READ THE ENTIRE OPINION CAREFULLY.

THE SPECIAL MEETING OF ETEC STOCKHOLDERS (Page 30)

   Time, Date And Place. A special meeting of the stockholders of Etec will be
held on [March/April]  , 2000, at the principal executive offices of Etec
located at 26460 Corporate Avenue, Hayward, California, at 10:00 a.m. local
time, to vote on the proposal to approve the merger agreement.

   Record Date And Voting Power For Etec. You are entitled to vote at the
special meeting if you owned shares of Etec common stock at the close of
business on        , 2000, the record date for the special meeting. You will
have one vote at the special meeting for each share of Etec common stock you
owned at the

                                       5
<PAGE>

close of business on the record date. There are [   ] shares of Etec common
stock entitled to be voted at the special meeting.

   Etec Required Vote. The approval of the merger agreement requires the
affirmative vote of a majority of the shares of Etec common stock outstanding
at the close of business on the record date.

   Share Ownership Of Management. The directors and executive officers of Etec
own approximately [  ]% of the shares entitled to vote at the special meeting.
All of the directors and executive officers of Etec have agreed to vote their
shares in favor of the proposal to approve the merger agreement.

INTERESTS OF ETEC OFFICERS AND DIRECTORS IN THE MERGER (Page 45)

   When considering the recommendation by the Etec board of directors, you
should be aware that a number of Etec's officers and directors have interests
in the merger that are different from other Etec stockholders.

CONDITIONS TO THE MERGER (Page 54)

   The obligations of both Applied Materials and Etec to complete the merger
are subject to the satisfaction of certain conditions.

TERMINATION OF THE MERGER AGREEMENT (Page 56)

   Applied Materials and Etec can terminate the merger agreement under certain
circumstances.

TERMINATION FEE (Page 57)

   The merger agreement requires Etec to pay Applied Materials a termination
fee equal to $54 million if the merger agreement is terminated under certain
circumstances.

LIMITATION ON CONSIDERING OTHER ACQUISITION PROPOSALS (Page 53)

   Etec has agreed not to consider a business combination or other similar
transaction with another party while the merger is pending unless the other
party has made an unsolicited proposal to the Etec board of directors for a
superior transaction.

STOCK OPTION AGREEMENT (Page 59)

   In order for Applied Materials to proceed with the merger, Applied Materials
required Etec to grant Applied Materials an option to purchase newly issued
shares of Etec common stock representing up to 19.9% of the number of shares of
Etec common stock outstanding. The option is exercisable only under limited
circumstances in which a termination fee would be payable by Etec to Applied
Materials. The option's per share exercise price is $82.46, and the profit that
Applied Materials can recognize under the option is limited. The option could
discourage other companies from trying to acquire or combine with Etec before
Applied Materials and Etec complete the merger.

ANTICIPATED ACCOUNTING TREATMENT (Page 47)

   The merger is expected to be accounted for as a "pooling of interests" for
financial accounting purposes. This means that Applied Materials and Etec will
be treated as if they had always been combined for accounting and financial
reporting purposes.

                                       6
<PAGE>


NO DISSENTERS' RIGHTS

   Etec stockholders will not be entitled to dissenters' rights in connection
with the merger.

REGULATORY APPROVALS (Page 47)

   U.S. and German antitrust laws prohibit us from completing the merger until
we have furnished certain information and materials to the Antitrust Division
of the U.S. Department of Justice, the U.S. Federal Trade Commission and the
German anticompetition authority and a required waiting period has expired.
Applied Materials and Etec have each filed the required notification and report
forms with the Antitrust Division and the Federal Trade Commission, and have
filed the required notification with the German anticompetition authority. Even
if the required waiting periods expire, the Antitrust Division, Federal Trade
Commission and German anticompetition authority continue to have the authority
to challenge the merger on antitrust grounds before or after we complete the
merger.

   We cannot predict whether we will obtain all required regulatory approvals
for the merger, or whether any approvals will include conditions that would be
detrimental to Applied Materials or Etec.

   The following table sets forth the closing per share sales price of Applied
Materials common stock and Etec common stock, as reported on the Nasdaq

                                       8
<PAGE>

   The estimated equivalent per share price of Etec common stock equals the
exchange ratio of 0.649 multiplied by the price of a share of Applied Materials
common stock. You may use this calculation to determine what your shares of
Etec common stock will be worth if the merger is completed. If the merger had
occurred on February 7, 2000, you would have received a fraction of a share of
Applied Materials common stock worth $99.70 for each share of Etec common stock
you owned. The actual equivalent per share price of a share of Etec common
stock that you will receive if the merger is completed may be different from
this price because the per share price of Applied Materials common stock on the
Nasdaq National Market fluctuates continuously.

   Neither Applied Materials nor Etec has ever declared or paid cash dividends
on its common stock. The policies of Applied Materials and Etec are to retain
earnings for use in their respective businesses. Following the merger, Applied
Materials common stock will continue to be listed on the Nasdaq National
Market, and there will be no further market for Etec common stock.

              UNAUDITED PRO FORMA COMBINED SELECTED FINANCIAL DATA

   The unaudited pro forma combined selected financial information gives effect
to the proposed merger of Applied Materials and Etec to be accounted for as a
pooling of interests. The unaudited pro forma combined balance sheet data
presents the combined financial position of Applied Materials and Etec as of
their respective fiscal year-ends of October 31, 1999 and July 31, 1999
assuming that the proposed merger had occurred as of October 31, 1999. Such pro
forma information is based upon the historical consolidated balance sheet data
of Applied Materials at October 31, 1999 and Etec at July 31, 1999. The
unaudited pro forma combined statement of operations data gives effect to the
proposed merger of Applied Materials and Etec by combining the results of
operations of Applied Materials for the three years ended October 31, 1999 with
the results of operations of Etec for the three years ended July 31, 1999,
respectively, on a pooling of interests basis. The unaudited pro forma combined
selected financial data should be read in conjunction with the historical
financial statements and notes thereto of Applied Materials and Etec
incorporated by reference in this proxy statement/prospectus.

   The unaudited pro forma combined selected financial data are presented for
illustrative purposes only and are not necessarily indicative of the combined
financial position or results of operations of future periods or the results
that actually would have been realized had the entities been a single entity
during these periods.

outstanding. The pro forma data does not purport to be indicative of the
results of future operations or the results that would have occurred had the
merger been consummated at the beginning of the periods presented. The
information set forth below should be read in conjunction with the historical
financial statements and notes thereto of Applied Materials and Etec
incorporated by reference in this proxy statement/prospectus, and the selected
unaudited pro forma combined condensed financial data included elsewhere in
this proxy statement/prospectus. The unaudited pro forma combined and unaudited
pro forma equivalent per share data combine the results of operations of

    pro forma combined book value per share is computed by dividing pro forma
    stockholders' equity by the pro forma number of shares of Applied Materials
    common stock outstanding as of Applied Materials' fiscal year end assuming
    the merger had occurred as of these dates.

(3) The pro forma combined shares used in this calculation are equal to Etec's
    common and equivalent shares outstanding multiplied by the 0.649 exchange
    ratio, plus Applied Materials' common and equivalent shares outstanding.

(4) The shares used in this calculation are equal to the pro forma combined
    shares described in footnote (3) divided by the 0.649 exchange ratio.

                                 RISK FACTORS

   You should consider the following factors in evaluating whether to approve
the merger agreement. These factors should be considered in conjunction with
the other information included or incorporated by reference in this proxy
statement/prospectus.

Risks Relating to the Merger

 Failure to retain key employees could diminish the benefits of the merger.

   The successful combination of Applied Materials and Etec will depend in
part on the retention of key personnel. There can be no assurance that Applied
Materials will be able to retain Etec's key management, technical, sales and
customer support personnel, or that Applied Materials will realize the
anticipated benefits of the merger.

 If we are not successful in integrating our organizations, we will not be
 able to operate efficiently after the merger.

   Achieving the benefits of the merger will also depend in part on the
successful integration of Applied Materials' and Etec's operations and
personnel in a timely and efficient manner. Such integration requires
coordination of different development and engineering teams, marketing
personnel and service organizations. This, too, will be difficult and
unpredictable because of possible cultural conflicts and different opinions on
how best to run these operations. If we cannot successfully integrate our
operations and personnel, we may not realize the expected benefits of the
merger.

 Integrating our companies may divert management's attention away from our
 operations.

   Successful integration of Applied Materials' and Etec's operations,
products and personnel may place a significant burden on our management and
our internal resources. The diversion of management attention and any
difficulties encountered in the transition and integration process could harm
the combined company's business, financial condition and operating results.

 We may incur significant costs to integrate the companies into a single
 business.

   Applied Materials expects to incur costs for integrating Etec's operations,
products and personnel. These costs may be substantial and may include costs
for:

  . employee redeployment, relocation or severance;

  . conversion of information systems;

  . combining teams and processes in various functional areas; and

  . reorganization or closures of facilities.

   We do not know whether Applied Materials will be successful in these
integration efforts and cannot assure you that we will realize the expected
benefits of the merger.

 Etec stockholders will receive a fixed number of shares of Applied Materials
 common stock in the merger, not a fixed value.

   Upon completion of the merger, each Etec share will be converted into 0.649
of a share of Applied Materials common stock. As the exchange ratio is fixed,
the number of shares that Etec stockholders will receive in the merger will
not change, even if the market price of Applied Materials common stock
changes. There will be no adjustment to the exchange ratio or termination of
the merger based solely on fluctuations in

                                      14
<PAGE>

the price of Applied Materials common stock. In recent years, and particularly
in recent months, the stock market, in general, and the securities of
technology companies, in particular, have experienced extreme price and volume
fluctuations. These market fluctuations may adversely affect the market price
of Applied Materials common stock. The market price of Applied Materials common
stock upon and after completion of the merger could be lower than the market
price on the date of the merger agreement or the current market price. Etec
stockholders should obtain recent market quotations of Applied Materials common
stock before they vote on the merger.

Trends, Risks and Uncertainties Relating to Applied Materials

 The industry that Applied Materials serves is highly volatile and
 unpredictable.

   The semiconductor industry has historically been cyclical because of sudden
changes in supply and demand for semiconductors. Although semiconductors are
used in many different products, the markets for those products are
interrelated to various degrees. The timing, length and severity of these
cycles are difficult to predict. The health of the semiconductor manufacturing
equipment industry is affected by these semiconductor industry cycles. During
periods of declining demand for semiconductor manufacturing equipment, Applied
Materials must be able to quickly and effectively align its cost structure with
prevailing market conditions, to manage its inventory levels in order to reduce
the possibility of future inventory write-downs resulting from obsolescence,
and to motivate and retain key employees. During periods of rapid growth,
Applied Materials must be able to acquire and/or develop sufficient
manufacturing capacity and inventory to meet customer demand, and to attract,
hire, assimilate and retain a sufficient number of qualified people. The
inability of Applied Materials to achieve its objectives in a timely manner
during these industry cycles could have a material adverse effect on its
financial condition and results of operations.

 Applied Materials operates in a highly competitive industry characterized by
 increasingly rapid technological changes.

   Applied Materials' competitive advantage and future success depend on its
ability to successfully develop new products and technologies, develop new
markets in the semiconductor industry for its products and services, introduce
new products to the marketplace in a timely manner, qualify new products with
its customers, and commence and adjust production to meet customer demands.
There can be no assurance that Applied Materials will be able to conduct these
activities as successfully in the future as it has in the past.

   New products and technologies include those for new materials, including
copper and low-k dielectrics, 300mm wafers and 0.18 micron and below devices.
The introduction of new products and technologies grows increasingly complex
over time. If Applied Materials does not develop and introduce new products and
technologies in a timely manner in response to changing market conditions or
customer requirements, its financial condition and results of operations could
be materially and adversely affected.

 Applied Materials is exposed to the risks of operating a global business.

   Applied Materials has operations and sites located throughout the world to
support its sales and services to the global semiconductor industry. Managing
global operations and sites located throughout the world presents challenges
associated with, among other things, cultural diversities and organizational
alignment. Moreover, each region in the global semiconductor equipment market
exhibits unique characteristics that can cause, and in the past have caused,
capital equipment investment patterns to vary significantly from period to
period. Periodic economic downturns, trade balance issues, political
instability and fluctuations in interest and currency exchange rates are among
the many risks associated with operating a global business that could
materially and adversely affect demand for Applied Materials' products, systems
and related services.

                                       15

 Deterioration in the health of Asian economies could negatively affect
 Applied Materials' business.

   Applied Materials generates a significant portion of its revenue from
customers in Asian countries. Although Asian economies have stabilized to some
degree since early to mid-fiscal 1998, Applied Materials remains cautious
about general macroeconomic developments in Asia, particularly in Japan and
Taiwan. The economies of Japan and Taiwan are important to the overall
financial health of the Asian region, and if they deteriorate, the economies
of other countries, particularly those in Asia, could also be negatively
affected. Negative economic developments in Asia could have, and in the past
have had, a material adverse effect on demand for Applied Materials' products.

 Shifting or lower overall demand for personal computers may result in
 decreased demand for Applied Materials' products.

   Further shifts in demand from more expensive, high-performance personal
computers to lower-priced products (sub-$1,000 PCs), or lower overall demand
for PCs, could result in reduced profitability for, and lower capital spending
by, semiconductor manufacturers. This could have, and in the past has had, a
material and adverse effect on demand for Applied Materials' products.

 Dynamic Random Access Memory ("DRAM") prices are volatile, and a decrease in
 DRAM prices may result in customers canceling orders for, or delaying
 delivery of, Applied Materials' products.

   If DRAM prices decline to levels that do not allow manufacturers to operate
profitably, these manufacturers may cancel or delay orders for Applied
Materials' products, which could have, and in the past has had, a material and
adverse effect on Applied Materials' financial condition and results of
operations.

 Applied Materials is exposed to risks associated with acquisitions.

   Applied Materials may make acquisitions of, or significant investments in,
other businesses with complementary products, services and/or technologies.
Acquisitions involve numerous risks, including, but not limited to:

  . difficulties and increased costs in connection with integration of the
    personnel, operations, technologies and products of acquired companies;

  . diversion of management's attention from other operational matters;

  . the potential loss of key employees of acquired companies;

  . lack of synergy, or inability to realize expected synergies, resulting
    from the acquisition;

  . the risk that the issuance of Applied Materials common stock in the
    merger could be dilutive to Applied Materials stockholders if anticipated
    synergies are not realized; and

  . acquired assets becoming impaired as a result of technological
    advancements or worse-than-expected performance of the acquired company.

   For example, in fiscal 1998, Applied Materials recorded a $70 million pre-
tax expense for the write-down of purchased technology acquired in a previous
year that became impaired because of rapid changes in technology and
deteriorating business conditions. The inability to effectively manage
acquisition risks could materially and adversely affect Applied Materials'
business, financial condition and results of operations.

 Failure of critical suppliers to deliver sufficient quantities of product in
 a timely and cost-effective manner could negatively affect Applied Materials'
 business.

   Applied Materials uses numerous vendors to supply parts, components and
subassemblies (collectively "parts") for the manufacture and support of its
products. Although Applied Materials makes reasonable efforts to ensure that
parts are available from multiple suppliers, this is not always possible;
accordingly, some key parts may be obtained only from a single supplier or a
limited group of suppliers. Applied Materials has sought, and will continue to
seek, to minimize the risk of production and service interruptions and/or
shortages

                                      16
<PAGE>

of key parts by: 1) selecting and qualifying alternative suppliers for key
parts; 2) monitoring the financial stability of key suppliers; and 3)
maintaining appropriate inventories of key parts. There can be no assurance
that Applied Materials' results of operations will not be materially and
adversely affected if, in the future, Applied Materials does not receive in a
timely and cost-effective manner a sufficient quantity of parts to meet its
production requirements.

 Applied Materials' order backlog may be reduced by customer cancellations or
 delays, which could have a negative effect on Applied Materials' future
 sales.

   Applied Materials' backlog increased from $917 million at October 25, 1998
to $1.7 billion at October 31, 1999. Applied Materials schedules production of
its systems based upon order backlog and customer commitments. Backlog
includes only orders for which written authorizations have been accepted and
shipment dates within 12 months have been assigned. However, customers may
delay delivery of products or cancel orders, subject to penalties. Due to
possible customer changes in delivery schedules and cancellations of orders,
Applied Materials' backlog at any particular date is not necessarily
indicative of actual sales for any succeeding period. Delays in delivery
schedules and/or a reduction of backlog during any particular period could
have, and in the past have had, a material adverse effect on Applied
Materials' business and results of operations.

 Applied Materials is subject to the risk of business interruptions from
 implementing a new Enterprise Resource Planning System.

   Applied Materials recently implemented a new enterprise resource planning
system that replaced substantially all order fulfillment and manufacturing
applications. Significant interruption of Applied Materials' business
resulting from post-implementation issues such as system response time, vendor
software application code errors or system design and configuration problems
could result in delayed product deliveries or manufacturing inefficiencies,
which could materially and adversely affect Applied Materials' financial
condition and results of operations.

 Applied Materials' business is subject to the risk of interruptions from
 natural disasters such as earthquakes.

   Business interruptions can be caused by natural disasters or other
unplanned catastrophic events. Several offices and facilities of Applied
Materials and its customers and suppliers are located near major earthquake
faults in the United States and in certain foreign countries. In the event of
significant interruption to Applied Materials' business, or the businesses of
its customers or suppliers, resulting from a natural disaster or other
catastrophic event, Applied Materials' financial condition and results of
operations could be materially and adversely affected.

 Applied Materials is subject to risks associated with non-compliance with
 environmental regulations.

   Applied Materials is subject to environmental regulations related to the
disposal of hazardous wastes used in the development, manufacturing and
demonstration of its products. Applied Materials strives to exceed the
requirements of applicable environmental regulations and believes it is in
full compliance with these regulations. However, failure or inability to
comply with existing or future environmental regulations could result in
significant remediation liabilities, the imposition of fines and/or the
suspension or termination of production, each of which could have a material
adverse effect on Applied Materials' financial condition and results of
operations.

 Applied Materials is exposed to the risk that third parties may violate its
 proprietary rights or accuse Applied Materials of infringing upon their
 proprietary rights.

   Applied Materials' success is dependent upon the protection of its
proprietary rights. In the high-tech industry, intellectual property is an
important asset that is always at risk of infringement. Applied Materials
incurs costs to file for patents and defend its intellectual property and
relies upon the laws of the United States

                                      17
<PAGE>

and of foreign countries in which Applied Materials develops, manufactures or
sells its products to protect its proprietary rights. However, there can be no
assurance that these proprietary rights will provide competitive advantages, or
that other parties will not challenge, invalidate or circumvent these rights.
Infringement upon Applied Materials' proprietary rights by a third party could
result in uncompensated lost market and revenue opportunities for Applied
Materials.

   Other parties may assert that Applied Materials' products, systems,
processes or other technology infringe upon their patents or other intellectual
property rights. In such cases, Applied Materials evaluates its position and
considers the available alternatives, which may include seeking licenses to use
the technology in question on commercially reasonable terms or defending its
position. However, if Applied Materials is not able to negotiate the necessary
licenses on commercially reasonable terms or successfully defend its position,
Applied Materials' financial condition and results of operations could be
materially and adversely affected.

 Applied Materials is exposed to various litigation risks.

   Applied Materials is currently involved in litigation regarding patent
infringement, intellectual property rights, antitrust and other matters (see
Note 13 of Notes to Consolidated Financial Statements contained in Applied
Materials' 1999 Annual Report incorporated by reference herein), and could
become involved in additional legal proceedings or claims in the future. These
proceedings and claims, whether with or without merit, could be time-consuming
and expensive to defend, and could divert management's attention and resources.
There can be no assurance regarding the outcome of current or future legal
proceedings or claims.

 Applied Materials is exposed to exchange rate fluctuations.

   Significant operations of Applied Materials are conducted in foreign
currencies, primarily Japanese yen. Applied Materials actively manages its
exposure to changes in currency exchange rates, but there can be no assurance
that future changes in currency exchange rates will not have a material and
adverse effect on Applied Materials' financial condition or results of
operations.

 Applied Materials is subject to risks from Year 2000 issues.

   The information provided herein is a "Year 2000 Readiness Disclosure" for
purposes of the Year 2000 Information and Readiness Disclosure Act.

   Applied Materials established a Year 2000 Program Office to address Year
2000 issues through four key readiness programs. A brief description of the
activities under these programs is as follows:

   Internal Infrastructure Readiness Program. This program encompassed all
major categories of applications and hardware in use by Applied Materials.
Under this program, Applied Materials completed an inventory of applications
and information technology and non-information technology hardware, and
categorized them as either "mission critical" or "non-mission critical" based
upon certain factors, such as whether a failure of the application or hardware
could cause personal injury or significant disruption to any portion of Applied
Materials' business. All mission critical applications and hardware were tested
and remediated as appropriate. To date, Applied Materials has not experienced
any significant Year 2000 issues associated with its mission critical systems.

   Supplier Readiness Program. This program focused on minimizing two areas of
risk associated with suppliers: 1) a supplier's product integrity; and 2) a
supplier's ability to continue providing products and services in accordance
with Applied Materials' standards and requirements. In addition to products and
services from key suppliers that are used in manufacturing its products,
Applied Materials relies on commercial or governmental suppliers for
infrastructure-related services, including utilities, transportation,
financial, governmental, communications and other services. As of February 8,
2000, Applied Materials has not been affected by the Year 2000 issue associated
with these suppliers.


                                       18
<PAGE>

   Product Readiness Program. This program focused on identifying and resolving
Year 2000 issues existing in Applied Materials' products. Among other
activities, Applied Materials completed a Year 2000 readiness evaluation of its
current generation of released products based on a series of industry-
recognized testing scenarios and, as appropriate, addressed the Year 2000
issues associated with any component of its products. Unless otherwise
requested by a customer, all products that shipped on or after January 1, 1999
were Year 2000 ready. As of February 8, 2000, Applied Materials was not aware
of any significant Year 2000 issues directly related to a failure of its
products to be Year 2000 ready.

   Customer Readiness Program. This program focused on customer support issues,
including the coordination of retrofit activities for older generation
products, testing existing customer electronic transaction capability and
providing other services to Applied Materials' customers. This program also
included establishing a Year 2000 Customer Response Center to support customers
on and around January 1, 2000. This program will continue to make customer
support teams available through Applied Materials' second fiscal quarter of
2000 to assist customers who have chosen not to upgrade Applied Materials'
products or who experience any Year 2000 issues, including those associated
with the leap year.

   Year 2000 Issues of Acquired Companies. During fiscal 1999, Applied
Materials acquired Consilium, Inc. ("Consilium"), Obsidian, Inc. and Applied
Komatsu Technology, Inc. For the most part, the Year 2000 programs of these
companies were modeled after, or fully integrated into, Applied Materials' four
key readiness programs. As of February 8, 2000, Applied Materials was not aware
of any significant Year 2000 issues associated with any of these companies or
their products. However, as a software company, Consilium is assisting
customers in evaluating Year 2000 issues that may relate to Consilium's
products, and will continue to assist its customers in their Year 2000 efforts
after January 1, 2000.

   Estimated Costs. Applied Materials estimates that total Year 2000 costs will
range from $30 million to $40 million, with $27 million spent as of October 31,
1999. This amount includes costs to support customer satisfaction programs and
services and other internal costs, but does not include the cost of internal
hardware and software that was to be replaced in the normal course of business
but was accelerated because of Year 2000 capability concerns. The remaining
costs are for customer support programs and program office management, which
are planned to continue through Applied Materials' second fiscal quarter of
2000.

   Most Likely Worst-Case Scenario and Risks Associated with the Year 2000
Issue. The year 2000 is a leap year, and February 29, 2000 is a date frequently
associated with the Year 2000 issue. In addition, some Year 2000 issues may not
be discovered until well after January 1, 2000. Therefore, Applied Materials
believes risks associated with the Year 2000 issue may continue to exist after
January 1, 2000. Applied Materials believes its most likely worst-case
scenarios after January 1, 2000 will relate to undiscovered problems associated
with its products, due to the inability to anticipate every possible Year 2000
problem, or due to problems associated with the interaction between Applied
Materials' products and its customers' applications. A failure in Applied
Materials' products could result in claims against Applied Materials, increased
warranty or service costs, or a delay or loss of revenue, any of which could
materially and adversely affect Applied Materials' financial condition and
results of operations. Finally, Applied Materials believes it has taken steps
to identify and remediate Year 2000 issues under its various readiness
programs. However, if efforts to identify and address Year 2000 issues in
Applied Materials' products, customer and supply base, or infrastructure were
not successful, including those issues associated with the leap year, Applied
Materials may experience unanticipated problems that could materially and
adversely affect its financial condition and results of operations.

Trends, Risks and Uncertainties Relating to Etec

 Etec's revenues and operating results may fluctuate significantly.

   Etec's operating results have historically fluctuated significantly from
quarter to quarter and year to year. Its revenues in any quarter are highly
dependent on a relatively small number of unit sales occurring during that
quarter at relatively high prices. This causes unevenness in results of
operations from quarter to quarter. For example, two system shipments planned
for the second and third quarters of fiscal 1998 were delayed due to the
failure of a critical subassembly and to a problem in meeting a specification.
In addition, customer acceptance of one system was delayed from just prior to
the close of the quarter ended January 29, 2000 to two days after the close of
the quarter. In each case, Etec instead recognized revenue for each of these
systems in the next quarter. However, these delays caused Etec to miss its
revenue and earnings plan for the second quarters of fiscal 1998 and fiscal
2000.

   Installing and integrating maskmaking equipment requires a substantial
investment by a customer. In addition, Etec's systems typically have a lengthy
sales cycle. Customers often require a significant number of product
presentations and demonstrations. Substantial interaction with Etec's senior
management is also required before reaching a sufficient level of confidence in
a system's performance characteristics and compatibility with the customer's
target applications to place an order. During the entire sales cycle, Etec may
expend substantial funds and management time and effort with no assurance that
a sale will result.

   Based on Etec's past experience, Etec believes that the following are among
the principal factors that may cause fluctuations:

  . the timing of significant orders;

  . order cancellations and shipment reschedulings;

  . unanticipated delays in design, engineering or production or in customer
    acceptance of product shipments;

  . the cyclicality of the maskmaking and semiconductor industries;

  . the lengthy sales and production cycle for Etec's products; and

  . the mix of systems sold and the relative proportions of product revenues
    and service revenues.

   Other factors that could cause fluctuations include patterns of capital
spending by Etec's customers, pricing changes, the timing of product
announcements or introductions by Etec or its competitors, the availability of
components and subassemblies, expenses associated with acquisitions, disruption
in operations due to an earthquake or other natural disaster and exchange rate
fluctuations.

   It generally takes Etec about six months to manufacture a system. Because
Etec's backlog is relatively low compared to historical levels, Etec may start
manufacturing a system before it has a firm order for that system. If the
anticipated order does not materialize and Etec has no other customer who wants
that system, Etec has inventory exposure. This risk is of particular concern to
Etec due to the lengthy sales cycle required to obtain an order for a system
and the costs already expended to manufacture each system.

   Given the extreme sensitivity of the securities markets to deviations from
expected quarterly results, fluctuations in quarterly results such as those
described above can result in high volatility of Etec's stock price.

 Etec's operating results are seriously affected by the cyclical nature of the
 maskmaking and semiconductor industries, as well as the capital spending
 decisions of customers.

   Etec's operating results depend on capital expenditures by maskmakers and
semiconductor companies, which in turn depend on the current and anticipated
demand for masks, integrated circuits made from masks, and products that use
such integrated circuits. The overall semiconductor industry has been, and is
likely to continue to be, cyclical with periods of oversupply. Etec experienced
a significant downturn in demand for its

                                       20
<PAGE>

products in fiscal 1999. Although Etec is optimistic that demand will improve
as the semiconductor business improves, it is not certain that the level of
demand will materially improve in fiscal 2000. Etec's ability to reduce
expenses in response to a downturn is limited by the need for continued
investment in research and development and in customer service and support.
Previous downturns in capital investment by the maskmaking industry have
materially hurt Etec's business. Future downturns may have similar material
adverse effects. In addition, due to changes in semiconductor manufacturing
technology, demand for maskmaking equipment has at times been depressed while
demand for semiconductor devices has remained strong. A downturn in demand for
maskmaking equipment would decrease Etec's revenues and adversely affect
Etec's financial results.

 Competitive pressures may cause Etec to lose potential sales or force it to
 reduce its prices, either of which would result in reduced revenues.

   The maskmaking equipment industry is highly competitive. Etec believes that
the principal competitive factors in its industry are product performance,
service, technical support, system price, speed, reliability, ease of upgrade
and the customer's cost of ownership and production. To remain competitive,
Etec believes that it must invest significant financial resources in new
product development and in customer service and support centers worldwide.

   Etec currently competes worldwide with a number of U.S. and foreign
manufacturers, including Hitachi, Ltd., Japan Electron Optical Laboratory,
Ltd. ("JEOL"), Toshiba Corp., and Leica Microsystems, AG. Some of these
competitors have substantially greater financial, manufacturing, marketing,
and customer service and support capabilities than Etec does. In addition,
some competitors have entered into strategic relationships or alliances with
leading semiconductor manufacturers. In particular, Etec believes that
Japanese competitors such as Hitachi and JEOL have long-standing collaborative
relationships with Japanese and other Asian semiconductor manufacturers.
Because of the significant investment required to install and integrate
maskmaking equipment, Etec also believes that, at any particular site, a
customer may rely upon a single maskmaking equipment vendor for multiple
generations of equipment. This makes it difficult to achieve significant sales
into that particular site once a competitor's system has been selected.

   Etec has felt some pricing pressures from its customers from time to time.
These pressures will intensify if Etec's competitors are successful in
introducing systems with improved performance over their current product
offerings. Competitors may develop future generations of products that are
superior in features, cost or other factors to Etec's product offerings.
Development of a clearly superior competitive product for mask pattern
generation would materially adversely affect Etec's business. In addition,
potential customers who may not need all of the functionality and technical
capability of Etec's systems may instead purchase lower priced systems from
its competitors.

 Etec must develop new technologies, products and enhancements to respond to
 changes in its industry.

   Etec's business is characterized by rapid technological change and evolving
industry standards. As a result, Etec must enhance its existing products and
develop, manufacture and successfully introduce new products and upgrades with
improved capabilities. Any significant delay in the development, manufacture
or market acceptance of new products, or in the enhancement of existing
products, would materially adversely affect Etec's business. Etec's
Interconnect Products Group's ("IPG") DigiRite 2000 has not yet achieved
market acceptance and that business continues to generate a loss. Etec's flat
panel display testing product is still in the development stage. There can be
no assurance that Etec will be successful in selecting, developing,
manufacturing and marketing new technology, products or enhancements of its
existing products.

   Changes in mask or semiconductor manufacturing processes could also
adversely affect Etec's business. Etec anticipates continued development of
product or process technologies that extend the useful lives of previously
sold maskmaking tools. For example, Etec's sales were materially adversely
affected for several years from the mid-1980s to the early 1990s due to the
introduction of semiconductor manufacturing equipment that allowed
semiconductor companies to manufacture several generations of smaller chips
with older

                                      21
<PAGE>

technology masks, thereby eliminating the need for new generations of masks.
Etec could also lose business if a direct write technology is perfected that is
not bound by the current limitations of that technology. There can be no
assurance that Etec will be able to develop, manufacture and sell products that
respond adequately to such changes. In addition, Etec may incur substantial
unanticipated costs to ensure the functionality and reliability of its future
product introductions early in the product's life cycle. If new products have
reliability or quality problems, Etec may experience reduced orders, higher
manufacturing costs, delays in collecting accounts receivable or additional
service and warranty expenses.

   Etec obtains research and development funding from governmental and quasi-
governmental agencies such as the Department of Defense Advanced Research
Projects Agency and International SEMATECH for certain projects. Aggregate
funding from all such sources amounted to $8.7 million, $6.1 million and $2.0
million in fiscal 1999, 1998 and 1997, respectively. These cooperative
development contracts set technology milestones that Etec must meet by
specified dates to receive the funding. If Etec is unable to meet the
technology milestones necessary to secure funding under such contracts, its
research and development expenses in fiscal 2000 will be higher than currently
expected. This, in turn, would materially adversely affect Etec's financial
results.

 The failure of any of Etec's sole source suppliers to provide components on a
 timely basis would harm Etec's business.

   Although Etec manufactures some of the components and subassemblies used in
its systems, many of the components and subassemblies used in Etec's systems
are purchased from subcontractors. None of Etec's suppliers is obligated to
provide it with any specific quantity of components or subassemblies over any
specific period. Most of the components and subassemblies included in Etec's
products are obtained from a single supplier or a limited group of suppliers.
In particular, Etec relies on sole-source suppliers for electron beam sources
for its MEBES systems, high-voltage power supplies, certain lasers, lenses and
other critical components. Etec has generally been able to obtain adequate,
timely delivery of critical subassemblies and components, although it has
experienced occasional delays. Any inability to obtain adequate, timely
deliveries of subassemblies and components could prevent Etec from meeting
scheduled shipment dates. This could damage relationships with Etec's current
and prospective customers and, as a result, materially adversely affect Etec's
business.

 Etec relies on a small number of customers who purchase systems sporadically,
 making the loss of any customer very harmful to Etec's business.

   Etec derives most of its annual revenue from the sale of a small number of
systems and upgrades. The price of Etec's systems currently ranges from
approximately $6 million to approximately $13 million for MEBES and ALTA
systems, and from approximately $1 million to approximately $7 million for
upgrades. In fiscal 1999, Etec sold a total of 17 new systems and 1 factory
upgrade to 11 customers. In each of the last three fiscal years, at least one
customer has accounted for more than 10% of Etec's revenue for the fiscal year.
Etec expects that sales to relatively few customers will continue to account
for a high percentage of its revenues in any accounting period in the
foreseeable future.

   There are a relatively small number of potential customers worldwide for
mask production systems. Product sales to Etec's ten largest customers
accounted for approximately 75%, 79% and 73% of revenue in fiscal 1999, 1998
and 1997, respectively. Sales to the largest customer during each of those
periods accounted for approximately 17%, 17% and 16% of total revenue,
respectively. If Etec loses a customer's business due to customer
dissatisfaction or competition, it is difficult to replace the revenue that had
previously come from that customer, particularly in light of the long lead time
required to obtain an order. The failure to replace such sales with sales to
other customers in succeeding periods would have a material adverse effect on
Etec's business. Additionally, a reduction in orders from any one customer or
the cancellation or delay of any significant order could have a material
adverse effect on Etec's business, financial condition and results of
operations.

                                       22

 Etec's sales could decline if customer relationships are disrupted by the
 merger.

   Etec's customers may not continue their current buying patterns during the
pendency of, and following, the merger. Any significant delay or reduction in
orders for Etec products could reduce revenues and hurt Etec's business.
Customers may defer purchasing decisions as they evaluate the likelihood of
successful integration of Applied Materials' and Etec's products and the
combined company's future product strategy. Customers may also consider
purchasing products of competitors.

 If the merger is not completed, Etec's stock price and future business and
 operations could be harmed.

   If the merger is not completed, Etec may be subject to the following
material risks, among others:

  . Etec may be required to pay Applied Materials a termination fee of $54
    million as described on page 57;

  . the option granted to Applied Materials by Etec may become exercisable
    and if exercised may make another business combination more difficult;

  . Applied Materials could require Etec to purchase the option or shares of
    Etec common stock that Applied Materials acquired under the option,
    resulting in additional costs to Etec;

  . the price of Etec common stock may decline to the extent that the current
    market price of Etec common stock reflects a market assumption that the
    merger will be completed; and

  . Etec's costs related to the merger, such as legal, accounting and some of
    the fees of its financial advisor, must be paid even if the merger is not
    completed.

   Further, if the merger is terminated and Etec's board of directors
determines to seek another merger or business combination, it is not certain
that it will be able to find a partner willing to pay an equivalent or more
attractive price than that which would be paid in the proposed merger with
Applied Materials. In addition, while the merger agreement is in effect and
subject to limited exceptions described on page 53 of this proxy
statement/prospectus, Etec is generally prohibited from soliciting, initiating
or encouraging or entering into extraordinary transactions, such as a merger,
sale of assets or other business combination, with any party other than
Applied Materials.

 If either of Etec's manufacturing facilities is damaged by a natural
 disaster, system production would be delayed and manufacturing costs would
 increase.

   Etec conducts all of its manufacturing activities for its core products at
its leased facilities in Hayward, California and Hillsboro, Oregon. Etec's
Hayward campus, which includes the corporate headquarters, is located in a
seismically active area. Although Etec maintains business interruption
insurance, a major catastrophe (such as an earthquake or other natural
disaster) at the Hayward or Hillsboro sites could result in a prolonged
interruption of Etec's business. All of Etec's MEBES electron-beam systems are
currently produced in Hayward, and all of its ALTA laser-beam systems are
currently produced in Hillsboro. Through the completion of the facilities
expansions in Oregon and California, Etec is now capable of producing MEBES
and ALTA systems in either location. However, any change in production would
cause delays and higher manufacturing costs.

 The cost of Etec's new facilities will adversely affect gross margins.

   In fiscal 1999, Etec completed a new manufacturing facility in Hillsboro,
Oregon and expanded its manufacturing facility in Hayward, California. The
additional cost of these two new facilities increased Etec's manufacturing
costs beginning in the fourth quarter of fiscal 1999. The production
capacities of these two facilities are not fully utilized. Accordingly, the
fixed costs of the excess capacity are expected to adversely impact gross
margins in fiscal 2000. There can be no assurance that the capacity
utilization will ever be adequate to offset these costs fully.

                                      23
<PAGE>

 If Etec cannot successfully integrate acquired businesses, its business and
 financial results will suffer.

   Etec's business strategy includes expanding its product lines and markets
through acquisitions. Any acquisition may result in potentially dilutive
issuances of equity securities, the incurrence of debt and contingent
liabilities, potential reductions in income due to losses incurred by the
acquired business, and amortization expense related to intangible assets
acquired, any of which could materially adversely affect Etec's financial
condition and results of operations.

   In March 1997, Etec acquired Ebetech Electron Beam Technology GmbH, renamed
Etec EBT. This subsidiary (which is part of the Display Products Group) is
engaged in the development of focused electron-beam test systems for flat panel
displays. These products are currently in the preliminary development and
marketing stage, and there can be no assurance that Etec will be able to
introduce them successfully into the market.

   In February 1996, Etec acquired Polyscan, Inc., a development-stage company
based in Tucson, Arizona, that designs and develops laser direct imaging
systems for printed circuit boards. Polyscan, Inc. has subsequently been merged
into Etec's operations and has become Etec's IPG. IPG recognized revenue on one
system in fiscal 1998 and four systems in fiscal 1999, and this business unit
has incurred losses since its inception. Etec expects that IPG will continue to
incur losses for the foreseeable future. Etec has never operated in the market
segments targeted by IPG.

   There can be no assurance that Etec will be able to integrate IPG
successfully into its current business operations or will be able to integrate
the technology into Etec's product development strategy or to manufacture,
market and sell its products successfully, or that its business will ever
become profitable. There can be no assurance of the effect of any future
acquisition on Etec's business or operating results.

 Etec is subject to a number of risks associated with international sales and
 operations.

   Sales to Etec's customers in countries other than the United States
accounted for 62%, 74%, and 72% of revenues in fiscal 1999, 1998 and 1997,
respectively. Etec anticipates that international sales will continue to
account for a significant portion of its revenues for the foreseeable future.
Sales and operations outside of the United States are subject to certain
inherent risks. These risks include:

  . fluctuations in the value of the U.S. dollar relative to foreign
    currencies;

  . longer accounts receivable collection cycles;

  . tariffs, quotas, taxes, and other market barriers;

  . political and economic instability;

  . restrictions on the export or import of technology;

  . potentially limited intellectual property protection;

  . difficulties in staffing and managing international operations; and

  . potentially adverse tax consequences.

   Any of these factors could adversely affect Etec's business. In particular,
although Etec's international sales are primarily denominated in U.S. dollars,
currency exchange fluctuations in countries where it does business, such as
those experienced recently in certain Asian countries, could materially
adversely affect Etec's business.

   Some of Etec's products may not be sold outside of the United States except
pursuant to an export license from the United States Department of Commerce.
Etec has not experienced significant delays in obtaining such licenses, but
future sales could be subject to delay due to export license or other
regulatory requirements.

                                       24
<PAGE>

 Etec is subject to governmental regulations and must comply with industry
 standards.

   Etec is subject to a variety of governmental regulations relating to the
use, storage, discharge, handling, emission, generation, manufacture and
disposal of toxic or other hazardous substances. In addition, Etec is subject
to certain packaging and take-back packaging requirements in Europe. Etec
believes that it is currently in compliance in all material respects with such
regulations and that it has obtained or will obtain all material environmental
permits necessary to conduct its business. Nevertheless, if Etec fails to
comply with current or future regulations, substantial fines could be imposed
on Etec. It also might be forced to suspend production, to alter its
manufacturing process or to cease operations. Such regulations could also
require Etec to acquire expensive remediation or abatement equipment or incur
substantial expenses to comply with environmental regulations. Any failure by
Etec to control the use, disposal, or storage of, or adequately restrict the
discharge of, hazardous or toxic substances could subject Etec to significant
liabilities.

   Etec's products and worldwide operations are also subject to numerous
governmental regulations designed to protect the health and safety of
operators of manufacturing equipment. Etec believes that its products
currently comply with all material governmental health and safety regulations
and with the voluntary industry standards currently in effect. In part because
the scope of future regulations and standards cannot be predicted, there can
be no assurance that Etec will be able to comply with any future regulations
or industry standards. Noncompliance could result in governmental restrictions
on sales or reductions in customer acceptance of Etec products. Compliance may
also require significant product modifications, potentially resulting in
increased costs and impaired product performance.

 Etec may need to raise additional capital in the future, and it may not be
 available.

   The development, manufacture and marketing of pattern generation systems
are highly capital intensive. Etec has budgeted approximately $29 million of
capital expenditures in fiscal 2000, with other assets to be financed under
operating leases. Etec expects that its anticipated cash flow from operations,
existing cash balances and availability under its revolving credit facility
will satisfy its cash requirements for at least the next 12 months. To the
extent that such cash resources are insufficient to fund its activities, Etec
would need to raise additional funds. There can be no assurance that Etec
could obtain additional financing on reasonable terms or at all. If additional
capital is raised through the sale of equity or convertible debt securities,
dilution to Etec stockholders could occur.

 Etec may have to defend against intellectual property litigation, which could
 be costly and detrimental to its business.

   Semiconductor-related industries have experienced substantial litigation
regarding patent and other intellectual property rights. As is typical in the
industry, Etec has from time to time received, and may in the future receive,
communications from third parties alleging infringements of patents and other
intellectual property rights. In the future, protracted litigation may be
necessary to defend Etec against alleged infringement of others' rights. Any
such litigation, even if Etec is ultimately successful in its defense, could
result in substantial cost and diversion of time and effort by management.
This in and of itself could have a material adverse effect on Etec's business,
financial condition and results of operations. Further, adverse determinations
in such litigation could result in Etec's loss of proprietary rights, subject
Etec to significant liabilities (including treble damages under certain
circumstances), require Etec to seek licenses from third parties, or prevent
Etec from manufacturing or selling its systems.

   In January 2000, a declaratory judgment action was brought by Micronic
Laser Systems Inc., a company that is developing a laser mask writing tool to
compete with Etec's ALTA systems. The suit asked that a key patent owned by
Etec related to laser mask writing be declared either invalid or inapplicable
to Micronic tools. If Micronic were to be successful in the litigation, it
would be able to complete its development of a competitive product without
worrying about Etec's patent.

   The Lemelson Foundation has filed a suit against numerous semiconductor
manufacturers, claiming patent infringement of a number of basic U.S. patents
granted to Jerome Lemelson over many years. Some of these

                                      25
<PAGE>

semiconductor companies, and the attorneys for the Lemelson Foundation, have
also contacted semiconductor equipment companies and commercial maskmaking
companies, claiming potential liability for infringement of these same patents.
Etec, in turn, has been contacted by two of its customers, notifying it of the
fact that they have received claims and claiming that Etec may have
responsibility for indemnifying them under the terms of Etec's sales contracts
with the customers. Etec has reached a settlement with one customer, and
believes that it will be able to settle with the other customer on reasonable
terms, without any material adverse effect on Etec's business. However, there
can be no assurance that Etec will be able to do so, and the costs of a lengthy
litigation, or a judgment in which Etec is found liable, could have a material
adverse effect on Etec's business. In addition, we may receive similar claims
for indemnity from other U.S. customers who are pursued by the Lemelson
Foundation.

 Etec depends on its key employees to keep its business running smoothly.

   Etec's future operating results will depend significantly upon the continued
contributions of its officers and key management, engineering, manufacturing,
customer support and sales personnel, many of whom would be difficult to
replace. Etec does not have an employment agreement with any of its employees,
nor does it maintain key person life insurance with respect to any employee.
The loss of any key employee could have a material adverse effect on Etec's
business. Etec's employees are currently required to enter into a
confidentiality agreement as a condition of their employment. However, these
agreements do not expressly prohibit the employees from competing with Etec
after leaving. Some of Etec's former employees currently provide services or
technical support to Etec's customers or for its competitors. Etec's operating
results will depend in significant part upon its ability to attract and retain
qualified management, engineering, manufacturing, marketing, customer support
and sales personnel. Competition for such personnel is intense, and there can
be no assurance that Etec will be successful in attracting and retaining such
personnel. The failure to attract and retain such personnel could have a
material adverse effect on Etec's business.

 Etec's Year 2000 readiness disclosure.

   Etec established a formal project with a project office and project team to
address the Year 2000 issue and achieve Year 2000 (Y2K) Readiness. Etec chose
the U.S. Government Accounting Office ("GAO") Program Management Model, as
modified, to manage and measure its progress. The project focused on four key
readiness areas:

  1. Product readiness, addressing product functionality;

  2. Supplier readiness, addressing the preparedness of Etec's suppliers;

  3. Internal infrastructure readiness, addressing mission-critical internal
     information technology ("IT") and non-IT systems; and

  4. Customer readiness, addressing customer preparedness and Etec's customer
     support.

   For each readiness area, Etec systematically performed an enterprise-wide
risk assessment, implementing the GAO Program Management Model as a project,
and developing contingency plans to mitigate unknown risk. Etec also
communicated with its customers, suppliers, employees and other third-party
business partners to reinforce awareness and to inform them of its progress
toward Year 2000 Readiness. Etec did this through a variety of media. Etec's
Y2K web site provided a comprehensive report on its efforts, the status of
product testing and validation, and field implementation. As defined by Etec's
Y2K Project, Etec completed the Awareness and Assessment phases, representing
40% of the project effort, the Renovation phase, representing 10% of the
project effort and the implementation phase, representing 50% of the project
effort. Etec engaged a third party who assessed the comprehensiveness of Etec's
Y2K effort and schedule.

   Product Readiness: A comprehensive set of tests was used to test all of
Etec's products. This process provided a complete assessment of potential Y2K
impacts and precluded inefficient use of resources that would result from the
performance of individual customer test suites. Etec performed its testing in
accordance with International SEMATECH Year 2000 Test Scenarios guidelines. All
of Etec's products completed the

                                       26
<PAGE>

renovation and validation phases and field upgrades were released. Etec
installed these upgrades in its customers' systems through its standard Service
Update Plan Process. The upgrade schedule was determined by customer
requirements. Etec will offer all of its customers the opportunity to install
this upgrade for any problems through the first calendar quarter of 2000. No
problems have been reported by customers through February 8, 2000.

   Supplier Readiness: This aspect of the program focused on minimizing risk
associated with Etec's suppliers in two areas: first, the supplier's capability
to provide Y2K compliant products and second, the supplier's business
capability to continue to provide the required products and services. Etec used
the International SEMATECH Year 2000 Readiness Supplier Questionnaire as an aid
in assessing risk. A supplier action list and contingency plans were developed
based upon this assessment. No problems with suppliers have been experienced
through February 8, 2000.

   Internal Infrastructure Readiness: Etec has completed an assessment of its
IT and non-IT applications and its business processes. All applications and
processes have already been made Y2K compliant.

   Cost: Etec estimated that the total Y2K project costs would range from $5 to
$8 million. Approximately 90% of the projected costs has been incurred through
October 31, 1999, with the remainder expected to be spent over the next two
fiscal quarters. There can be no assurance that this estimate will be
sufficient or that actual costs will not differ materially from the current
estimate.

   Worst-Case Scenario: Etec believes that its most reasonably likely worst-
case scenario would be the failure of services, supplies or products provided
by third parties. As Etec has little or no control over remediating the Y2K
problems of third parties such as utilities, telecommunication providers,
computer system and software suppliers, the risks are relatively more difficult
to assess than with the Etec's internal systems or its products. Third party
failures could disrupt Etec's operations and could have a material adverse
effect on its financial condition. Etec is not in a position to identify all
possible scenarios, nor can it estimate the impact of such disruptions.
However, no such problems have been experienced through February 8, 2000.

   Various disclosures and announcements of Etec concerning its products and
Y2K Readiness Program are intended to constitute "Year 2000 Readiness
Disclosures" as defined in the Year 2000 Information and Readiness Disclosure
Act.

 Etec's stock price is subject to significant fluctuations.

   Since Etec's initial public offering in October 1995, the price of Etec
Common Stock has fluctuated widely, with closing sales prices on the Nasdaq
National Market ranging from $7.65 to $94.38. Etec believes that factors such
as the risks described herein or other factors could cause the price of its
Common Stock to fluctuate, perhaps substantially. In addition, in recent years
the stock market in general, and the market for high technology stocks in
particular, has experienced extreme price fluctuations, which have often been
unrelated to the operating performance of the affected companies. Such
fluctuations could adversely affect the market price of Etec Common Stock.

 Effects of recent accounting pronouncements on Etec.

   In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, "Accounting for Derivative Instruments
and Hedging Activities" ("SFAS 133"). SFAS 133 establishes a new model for
accounting for derivatives and hedging activities and supersedes and amends a
number of existing accounting standards. SFAS 133 requires that all derivatives
be recognized in the balance sheet at their fair market value, and the
corresponding gains or losses be either reported in the statement of operations
or as a deferred item depending on the type of hedge relationship that exists
with respect to such derivative. SFAS No. 137, "Accounting for Derivative
Instruments and Hedging Activities--Deferral of Effective Date of FASB
Statement No. 133", is effective for all fiscal quarters and years beginning
after June 15, 2000. Etec has not yet determined the effect of adopting SFAS
133, which will be effective for Etec's fiscal year 2001.

                                 THE COMPANIES

Applied Materials

   Organized in 1967, Applied Materials develops, manufactures, markets and
services semiconductor wafer fabrication equipment and related spare parts for
the worldwide semiconductor industry. Customers for these products include
semiconductor wafer manufacturers and semiconductor integrated circuit ("IC"
or chip) manufacturers, who either use the ICs they manufacture in their own
products or sell them to other companies. These ICs are the key components in
most advanced electronic products such as computers, telecommunications
devices, automotive engine management systems and electronic games.

   During fiscal 1999, Applied Materials purchased the remaining 50 percent of
Applied Komatsu Technology, Inc. ("AKT") that it did not previously own. AKT
supplies equipment for fabricating flat panel displays ("FPDs") that are used
in notebook PCs, desktop monitors, TVs and other applications. Applied
Materials also acquired Consilium, a supplier of integrated semiconductor and
electronics manufacturing execution systems and services and Obsidian, Inc. a
developer of fixed-abrasive chemical mechanical polishing solutions for the
semiconductor industry.

   Applied Materials was incorporated in California in 1967 and reincorporated
in Delaware in April 1987.

   Products. Applied Materials currently manufactures equipment that performs
most of the primary steps in the chip fabrication process, including physical
and chemical deposition electroplating, etch, ion implantation, rapid thermal
processing, chemical mechanical polishing, metrology and wafer/reticle
inspection.

   Facilities. In addition to corporate facilities in Santa Clara, California,
Applied Materials maintains research, development and manufacturing centers in
the United States, Israel, Europe and Japan, as well as technology centers in
South Korea and Taiwan. To support a growing worldwide customer base, sales
and service offices are located in the United States, Europe, Israel, Japan,
South Korea, Taiwan, Singapore and the People's Republic of China.

Merger Sub

   Merger Sub is a wholly-owned subsidiary of Applied Materials incorporated
on December 28, 1999 in the State of Nevada. Merger Sub has not engaged in any
operations and exists solely to facilitate the merger.

Etec

   Etec designs, manufactures and markets patterning solutions that enable the
production of the faster, smaller and cheaper semiconductor chips and printed
circuit boards necessary for today's electronics. With a significant market
share for semiconductor IC mask pattern generation ("PG") equipment--equipment
that makes semiconductor masks--Etec is widely recognized for its expertise
with laser and electron-beam PG technologies. Etec is also leveraging
semiconductor solutions into the printed circuit board ("PCB") industry with
laser direct imaging technology. Etec's products consist of electron beam and
laser beam lithography systems. Etec sells these maskmaking systems through
its Semiconductor Products Group, offers its direct imaging systems to PCB
manufacturers through its Interconnect Products Group, and has begun marketing
its flat panel display testing product through its Display Products Group. The
company's systems are designed to provide a low cost of production for the
customer through high performance, reliability and ease of maintenance.

   Etec is the only maskmaking equipment manufacturer currently offering both
electron beam and laser beam systems. The different characteristics of
electron beam and laser beam systems address different segments of the mask
pattern generation market. Electron beam systems have a much smaller beam spot
size than laser beam systems and are best suited for leading-edge market
segments that require the highest resolution and accuracy. The primary
advantage of laser beam systems is their relative simplicity and higher
throughput compared to electron beam systems.

   Incorporated in 1989 under the laws of Nevada, Etec is headquartered in
Hayward, California.

                                      28
<PAGE>

   MEBES Electron Beam Systems. The MEBES electron beam products are designed
to meet the most technically demanding, leading-edge requirements of Etec's
customers. Over 175 MEBES systems have been produced, of which at least 120
were still in service as of July 31, 1999. MEBES systems currently sell for
approximately $6 million to $13 million. Etec's latest electron beam system,
the MEBES 5500 system, was introduced in July 1999. This system delivers higher
productivity and finer resolution needed to produce newer, smaller generations
of semiconductor chips (0.18-micron production and 0.13-micron pilot
production). No MEBES 5500 systems shipped in fiscal 1999. The previous
generation MEBES 5000 first shipped in June 1998. The 5000 system allows pilot
production of complex masks for 0.18-micron devices. The throughput of the
MEBES 5000 is as much as eight times faster than its predecessor, the MEBES
4500.

   ALTA Laser Beam Systems. Etec currently offers a family of scanned laser
beam maskmaking systems. Compared to MEBES products, the ALTA line of products
offers lower cost for higher production volume with less technically demanding
specifications. Etec commenced shipment of the ALTA 3500 system in October
1997. The ALTA 3500 is designed for the production of masks for the 0.25-micron
generation of semiconductor devices. It currently sells for approximately $10
million.

   Upgrades and Accessories. Etec sells a variety of hardware and software
packages that are designed to enhance previously installed systems. These
include packages that improve performance, throughput and reliability. Upgrades
typically range in price from approximately $1 million to approximately $7
million, and accessories are typically priced at less than $1 million. From
time to time, Etec also repurchases, refurbishes, and resells a limited number
of systems.

   New Product Areas. Etec is in the initial stages of establishing its
Interconnect Products Group ("IPG") product in the PCB industry. The DigiRite
2000 system, which first shipped in March 1998, allows a PCB manufacturer to
transfer computer-generated patterns directly to printed circuit boards,
significantly reducing the intermediate steps associated with printing patterns
on masks. This allows the manufacturer to print more complex patterns,
eliminate set-up time, and reduce cost for low-volume, high-complexity advanced
PCB products. In fiscal 1999, revenue from IPG products was less than $3
million. Etec also is developing focused electron-beam test systems for flat
panel displays through its Display Products Group. These products are currently
in the development stage. There can be no assurance that Etec will be able to
introduce them successfully into the market.

   Customers. Etec's Semiconductor Products Group customers include both
captive and merchant mask shops. Captive mask shops are owned by semiconductor
chip manufacturing companies and are generally used for internal production of
masks by such companies for their own use. Merchant mask shops make and sell
masks to a variety of semiconductor chip manufacturing companies. Semiconductor
manufacturers employ their captive capabilities largely to supply portions of
their own requirements for masks, while merchant mask shops sell masks to a
variety of semiconductor device manufacturers. Etec derives most of its annual
revenue from the sale of a small number of systems and upgrades. In fiscal
1999, Etec sold a total of 17 new systems and one upgrade to 11 customers. In
each of the last three fiscal years, at least one customer has accounted for
more than 10% of Etec's revenue for the fiscal year. Etec expects that sales to
relatively few customers will continue to account for a high percentage of
Etec's revenues in any accounting period in the foreseeable future.

   Marketing and Distribution. Etec markets and distributes its products
directly into its primary geographic markets, which consist of North America,
Japan, South Korea, Taiwan and Europe. Etec maintains sales offices in Arizona,
California, Japan, Germany, South Korea and Taiwan. Etec also uses sales
representatives for certain products in Taiwan and Europe.

                    THE SPECIAL MEETING OF ETEC STOCKHOLDERS

Date, Time and Place

   The special meeting of Etec stockholders will be held on [March/April]     ,
2000, at the principal executive offices of Etec located at 26460 Corporate
Avenue, Hayward, California, commencing at 10:00 a.m. local time. We are
sending this proxy statement/prospectus to you in connection with the
solicitation of proxies by the Etec board of directors for use at the Etec
special meeting and any adjournments or postponements of the special meeting.

Purpose of the Special Meeting

   The purpose of the special meeting is to consider and vote upon a proposal
to approve the merger agreement.

Recommendation of the Etec Board of Directors

   THE ETEC BOARD OF DIRECTORS HAS CONCLUDED THAT THE PROPOSAL TO APPROVE THE
MERGER AGREEMENT IS ADVISABLE AND IN THE BEST INTERESTS OF ETEC AND ITS
STOCKHOLDERS AND HAS UNANIMOUSLY APPROVED THE MERGER AGREEMENT. ACCORDINGLY,
THE ETEC BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT ALL ETEC STOCKHOLDERS
VOTE "FOR" THE APPROVAL OF THE MERGER AGREEMENT.

Record Date and Voting Power

   Only holders of record of Etec common stock at the close of business on the
record date,         , 2000, are entitled to notice of, and to vote at, the
special meeting. There were approximately [          ] holders of record of
Etec common stock at the close of business on the record date, with
[           ] shares of Etec common stock issued and outstanding. Each share of
Etec common stock entitles the holder thereof to one vote on each matter
submitted for stockholder approval. See "Management and Other Information--
Beneficial Ownership of Etec Shares" for information regarding persons known to
the management of Etec to be the beneficial owners of more than 5% of the
outstanding shares of Etec common stock.

Voting and Revocation of Proxies

   All properly executed proxies that are not revoked will be voted at the
special meeting and at any adjournments or postponements of the special meeting
in accordance with the instructions contained in the proxy. However, if the
special meeting is adjourned to a date after         , 2000, a new record date
will be set by the board of directors of Etec and a new notice of the special
meeting will be sent to persons who hold shares of Etec's common stock as of
the new record date.

   If a holder of Etec common stock executes and returns a proxy and does not
specify otherwise, the shares represented by the proxy will be voted "for"
approval of the merger agreement in accordance with the recommendation of the
Etec board of directors. An Etec stockholder who has executed and returned a
proxy may revoke it at any time before it is voted at the special meeting by:
(a) executing and returning to Etec's Secretary a proxy bearing a later date,
or (b) filing or transmitting to Etec's Secretary another instrument or
transmission revoking the proxy. In order to change his or her vote, an Etec
stockholder may either submit a duly executed proxy bearing a later date or
attend the meeting and vote in person after revoking any proxy that was
previously submitted.

Quorum; Required Vote

   The presence, in person or by proxy, at the special meeting of the holders
of a majority of the shares of Etec common stock outstanding as of the close of
business on the record date is necessary to constitute a

                                       30
<PAGE>

quorum at the meeting. For this purpose, abstentions and broker non-votes will
count toward establishment of a quorum. The affirmative vote of the holders of
a majority of the shares of Etec common stock outstanding as of the record date
is required to approve the merger agreement. In determining whether the
proposal to approve the merger agreement has received the requisite number of
affirmative votes, abstentions and broker non-votes will have the same effect
as a vote against the proposal to approve the merger agreement.

   At the record date for the special meeting, the directors and executive
officers of Etec owned approximately [  ]% of the outstanding shares of Etec
common stock entitled to vote at the meeting. Stephen E. Cooper (also an
executive officer of Etec), Edward L. Gelbach, John B. McBennett, William Ryan
(also an executive officer of Etec), William T. Siegle, Takeshi (John) Suzuki,
Thomas M. Trent and Robert L. Wehrli, directors of Etec, and, William D.
Snyder, Paul A. Warkentin, William D. Cole, Trisha A. Dohren, Mark A. Gesley,
Leslie G. Polgar, and W. Russell Wayman, executive officers of Etec, have each
entered into a voting agreement with Applied Materials dated January 12, 2000.
They have agreed in the voting agreements to vote all shares of Etec common
stock owned by them as of the record date in favor of the proposal to approve
the merger agreement. They also granted Applied Materials irrevocable proxies
to vote their shares of Etec common stock in favor of the proposal to approve
the merger agreement. Approximately [  ] shares of Etec common stock, which
represents approximately [  ]% of the outstanding shares of Etec common stock
as of the record date, are subject to the voting agreements. See "Voting
Agreements."

Solicitation of Proxies

   In addition to solicitation by mail, the directors, officers, employees and
agents of Etec may solicit proxies from Etec stockholders by personal
interview, telephone, telegram or otherwise. Etec will bear the costs of the
solicitation of proxies from its stockholders, except that Applied Materials
and Etec will each pay one-half of the cost of printing this proxy
statement/prospectus. Arrangements will also be made with brokerage firms and
other custodians, nominees and fiduciaries who are record holders of Etec
common stock for the forwarding of solicitation materials to the beneficial
owners of Etec common stock. Etec will reimburse these brokers, custodians,
nominees and fiduciaries for the reasonable out-of-pocket expenses they incur
in connection with forwarding solicitation materials. Etec has engaged the
services of Morrow & Co., Inc. to distribute proxy solicitation materials to
brokers, banks and other nominees and to assist in the solicitation of proxies
from Etec stockholders for a fee of approximately $7,500 plus reasonable out-
of-pocket expenses.

Other Matters

   No other matters may be brought before the special meeting by anyone other
than the Etec board of directors. At the date of this proxy
statement/prospectus, the Etec board of directors does not know of any business
that it will present at the special meeting other than as set forth in the
notice accompanying this proxy statement/prospectus. If any other matters
should properly be brought before the special meeting by the Etec board of
directors, it is intended that a supplement or amendment to this proxy
statement/prospectus describing the matter will be sent to all Etec
stockholders entitled to vote.

Stockholder Proposals for the Etec 2000 Annual Meeting

   If the merger is not consummated, proposals of stockholders of Etec that are
intended to be presented by such stockholders at Etec's 2000 Annual Meeting and
that the stockholders desire to have included in Etec's proxy statement must be
received by the Secretary of Etec no later than July 1, 2000 in order that they
may be considered for possible inclusion in Etec's proxy statement and form of
proxy relating to that meeting.

   With respect to stockholder proposals that are not sought to be included in
Etec's proxy statement and form of proxy relating to the 2000 Annual Meeting,
Etec's bylaws require that advance notice of such proposals be given to Etec no
later than August 30, 2000. Under Etec's bylaws, in order to be deemed properly
presented, notice must be delivered to, or mailed and received by, Etec not
less than 60 days prior to the first anniversary of the day on which notice of
the prior year's annual meeting was mailed to stockholders. The

                                   THE MERGER

General Description of the Merger

   At the effective time, Merger Sub will be merged with and into Etec. Etec
will be the surviving corporation and will continue as a wholly-owned
subsidiary of Applied Materials. In the merger, each share of Etec common stock
outstanding at the effective time will automatically be converted into 0.649 of
a share of Applied Materials common stock, with cash paid for any fractional
share.

   Based on the number of shares of Applied Materials common stock and Etec
common stock outstanding as of the record date, [         ] shares of Applied
Materials common stock will be issuable pursuant to the merger agreement,
representing approximately [   ]% of the total Applied Materials common stock
to be outstanding after such issuance. This assumes that no Etec or Applied
Materials stock options are exercised between the record date and the effective
time.

Background

   The terms and conditions of the merger agreement and the merger are the
result of arm's length negotiations between representatives of Applied
Materials and representatives of Etec. Set forth below is a summary of the
background of these negotiations.

   Applied Materials and Etec have been familiar with each other's businesses
for many years. Senior executives of the two companies have encountered one
another in a variety of business and industry settings in previous years.

   On November 16, 1998 and July 19, 1999, the two companies entered into two
agreements under which they agreed to cooperate in the development of certain
technology. In connection with these agreements, senior management of the
companies met periodically thereafter.

   In early June 1999, Applied Materials' New Business Development department
prepared an assessment of Etec's business, On June 18, 1999, Kalman Kaufman,
Applied Materials' Vice President of Strategic Planning and New Business
Development and Nancy H. Handel, Vice President, Global Finance and Treasurer
presented this assessment to certain members of Applied Materials' senior
management, including: James C. Morgan, Chairman and Chief Executive Officer;
Dan Maydan, President; Sasson Somekh, Senior Vice President, Office of the
President; Joseph R. Bronson, Senior Vice President, Chief Financial Officer
and Chief Administrative Officer, Office of the President; David N.K. Wang,
Senior Vice President, Office of the President; and Joseph J. Sweeney, Vice
President, Legal Affairs and Intellectual Property. Several issues and specific
action items were identified for follow-up to further assess Etec, Etec's
business and its prospects, and the benefits and risks associated with Applied
Materials' potential entry into the mask pattern generation equipment market
through a strategic relationship with Etec.

   On August 24, 1999, Stephen Cooper, Chairman of the Board, President and
Chief Executive Officer of Etec, Kalman Kaufman and Joseph R. Bronson held a
meeting in which the representatives of Applied Materials expressed an interest
in exploring the possibility of a merger transaction involving Etec and Applied
Materials. Mr. Cooper agreed to discuss the matter with the Etec board of
directors at a meeting scheduled for August 31, 1999.

   During August 1999, Morgan Stanley & Co. Incorporated was orally engaged by
Applied Materials to advise Applied Materials on various topics related to a
possible transaction with Etec. The engagement of Morgan Stanley was
subsequently confirmed in writing under an engagement letter dated November 30,
1999. Also during August 1999, Goldman Sachs was orally engaged by Etec to
advise Etec on various topics related to a possible transaction with Applied
Materials.

   The board of directors of Etec discussed a potential strategic relationship
between Applied Materials and Etec at the Etec board meeting on August 31,
1999. At the meeting, Goldman Sachs, Etec's financial advisor, presented a
preliminary analysis of Etec's valuation to the Etec board. The Etec board
agreed with Stephen

                                       33
<PAGE>

Cooper's initial assessment that a merger transaction was probably not
appropriate at that time. However, Mr. Cooper also informed the Etec board that
he would continue to hold discussions with Applied Materials' management to
explore possible business synergies between the two companies.

   On September 1, 1999, Stephen Cooper called Kalman Kaufman and informed him
of the Etec board's position that a merger transaction did not seem appropriate
at that time. Nevertheless, Mr. Cooper also agreed to meet again with Applied
Materials' management to consider potential business synergies between the two
companies.

   On September 7, 1999, as part of the ongoing contacts between the two
companies' senior management, Joseph R. Bronson, Sasson Somekh and Kalman
Kaufman met with Stephen Cooper for dinner. At this meeting, they discussed
issues of common interest, including the possibility of a merger transaction
involving the two companies and the potential business synergies of such a
transaction.

   Executives of Applied Materials and Etec met again on September 8, 1999.
Prior to the meeting, Applied Materials and Etec entered into a mutual
standstill and confidentiality agreement. At the meeting, there were several
presentations by key Etec technologists. In addition, Stephen Cooper presented
to Sasson Somekh and Dan Maydan his view of Etec's prospects and its technology
and competitive position within the mask pattern generation market. Mr. Cooper
indicated his belief that the value of Etec, in consideration of various
factors, including Etec's technology, its market position and the expected
growth in demand for its products, was significantly higher than the current
trading price for Etec's common stock.

   On September 10, 1999, Kalman Kaufman and Nancy H. Handel, presented
information on the potential merger transaction to the Applied Materials board
of directors. This information included market analysis provided by Morgan
Stanley to assess Etec's market value and a summary of Etec's recent financial
performance. These presentations were for the purpose of providing information
to the board and not for the purpose of seeking its approval of a specific
transaction. The Applied Materials board of directors discussed the possible
synergies of combining Applied Materials with Etec and the likely benefits and
risks to Applied Materials if such a combination were to occur.

   On September 13, 1999, Applied Materials made a non-binding proposal to Etec
regarding a possible stock-for-stock merger transaction involving Etec and
Applied Materials. This proposal included, among other terms, a proposed
exchange ratio of 0.8175 of a share of Applied Materials stock for each share
of Etec stock. The closing price of Applied Materials' stock on September 13,
1999 was $76.00 and the closing price of Etec's stock on that date was $42.00.
The terms of this proposal implied an Etec stock price of $62.13 and an implied
valuation of Etec of approximately $1.36 billion. On that same day, the Etec
board of directors discussed the proposal and determined that, in view of the
disparity between Etec's view of the potential long-term value of Etec and
Applied Materials' view of Etec's value, further discussions between the two
companies would not be productive at that time.

   On September 14, 1999, Stephen Cooper relayed the Etec board's decision in
separate telephone conversations with Joseph R. Bronson and Kalman Kaufman, and
discussions regarding a potential merger were discontinued.

   On October 27, 1999, representatives of Goldman Sachs and Stephen Cooper
spoke by telephone about re-commencing discussions concerning a potential
merger involving Applied Materials and Etec. Stephen Cooper indicated that Etec
would be interested in re-commencing discussions with Applied Materials as a
result of a number of changes in circumstances, including the large increase in
the price of Applied Materials' stock since the previous discontinuation of
discussions, the expected successful completion of Etec's fiscal 2000 first
quarter and the improving outlook for the maskmaking industry.

   On November 16, 1999, representatives of Goldman Sachs spoke with Joseph R.
Bronson about Etec's interest in reviving discussions with Applied Materials.
Kalman Kaufman then called Stephen Cooper to set up a meeting.

                                       34
<PAGE>

   On November 19, 1999, representatives of Goldman Sachs informed Stephen
Cooper that Goldman Sachs had received an indication from Applied Materials
that it was interested in re-commencing discussions with Etec concerning a
possible merger. On the same day, Morgan Stanley provided Applied Materials
with an updated market analysis to assess Etec's market value and with a
summary of Etec's recent financial performance.

   On November 22, 1999, Joseph R. Bronson, Kalman Kaufman and Stephen Cooper
spoke by telephone regarding the terms of a possible merger.

   On December 7, 1999, Joseph R. Bronson advised certain members of Applied
Materials' board of directors of the current status of the discussions between
Etec and Applied Materials.

   On December 10, 1999, a scheduled meeting occurred between Joseph R. Bronson
and Kalman Kaufman of Applied Materials and Stephen Cooper of Etec. The
representatives of the two companies agreed that, subject to a number of
significant contingencies, including approval by both companies' boards of
directors and receipt of fairness opinions from their respective investment
bankers, as well as completion of due diligence, and agreement on various open
issues, the two companies would proceed towards negotiation and execution of a
merger agreement. Based on the changes in circumstances since September, the
representatives of the companies discussed key elements of the proposed
transaction, including a possible exchange ratio of 0.649 of a share of Applied
Materials stock for each share of Etec stock. The closing price of Applied
Materials' stock on December 10, 1999 was $109.44 and the closing price of
Etec's stock on December 10, 1999 was $42.75. At this exchange ratio, the
implied price of Etec stock (on December 10, 1999) was $71.03 and the implied
valuation of Etec was approximately $1.6 billion. The parties also discussed
the process for conducting additional due diligence investigations and timing
issues involved with the proposed merger.

   On December 11, 1999, Kalman Kaufman, Joseph R. Bronson, Stephen Cooper and
Trish Dohren, Senior Vice President, Corporate Services and Quality, of Etec,
met to further discuss the terms of the proposed transaction and the timetable
for the due diligence efforts.

   On December 12, 1999, Alexander Meyer, Managing Director, New Business
Development of Applied Materials, and W. Russell Wayman, Vice President and
General Counsel of Etec, spoke by telephone to discuss various personnel issues
and the due diligence process. Applied Materials then provided a comprehensive
due diligence request list to Etec and representatives of both companies and
their respective outside legal counsel and financial advisors exchanged various
telephone calls with a view toward preparing for additional due diligence
efforts. Due diligence continued through January 12, 2000.

   On December 14, 1999, the Etec board of directors met to discuss the
proposed merger with Applied Materials. The Etec board of directors discussed,
among other issues, issues related to valuation and potential synergies of a
potential merger, as well as potential combinations with other parties. During
the meeting, Goldman Sachs made a presentation regarding certain financial
aspects of the potential merger with Applied Materials.

   On December 15, 1999, Applied Materials and its outside legal counsel,
Cooley Godward LLP, circulated an initial draft of the merger agreement to Etec
and its attorneys, Wilson Sonsini Goodrich & Rosati, Professional Corporation.
Discussions regarding the terms of the merger agreement occurred continually
from this date through January 12, 2000, the date as of which the merger
agreement was executed by the parties.

   On December 17, 1999, Sasson Somekh, Dan Maydan and Kalman Kaufman met with
key Etec technologists to discuss technology issues related to Etec's products
and the status of Etec's new product development efforts.

   On December 20, 1999, the Etec board of directors met again to discuss the
proposed merger involving Etec and Applied Materials. The Etec board of
directors, members of Etec's management and representatives of

                                       35
<PAGE>

Etec's legal counsel and financial advisor discussed, among other things,
issues related to the proposed merger agreement. Goldman Sachs presented a
detailed financial analysis of the proposed merger. Wilson Sonsini discussed
the key legal issues presented by the proposed merger agreement and also made a
presentation to the Etec board of directors regarding its fiduciary duties in
analyzing the proposed merger.

   On December 22, 1999, Trish Dohren, Kalman Kaufman, Alexander Meyer and Bill
Coplin, Director, Compensation and Benefits of Applied Materials, met to
discuss Etec's benefits programs and other human resources-related due
diligence issues. On the same day, the companies jointly developed a timeline
detailing tasks that needed to be completed prior to signing a definitive
merger agreement.

   On December 23, 1999, counsel for Applied Materials prepared and sent to
counsel for Etec a second draft of a proposed form of merger agreement,
including the ancillary transactional documents.

   On December 29, 1999, representatives of Etec's Finance and Accounting
department, William Snyder, Vice President and Chief Financial Officer, and
John Mosunic, Controller, met with representatives of Applied Materials'
Finance and New Business Development departments, Morgan Stanley and
PricewaterhouseCoopers LLP, Applied Materials' independent auditors, to review
Etec's financial statements and Etec's forecasts.

   During the period from January 4, 2000 through January 12, 2000, management
of Applied Materials and Etec, together with their respective attorneys, Cooley
Godward and Wilson Sonsini, held extensive negotiations regarding the terms and
conditions of the merger agreement and other agreements relating to the
proposed transaction.

   On January 5, 2000, a due diligence meeting was held at the offices of
Goldman Sachs. Representatives of both Applied Materials and Etec made
presentations and answered questions at the meeting. The attendees included:
Joseph R. Bronson, Sasson Somekh, David N. K. Wang, Kalman Kaufman, Nancy H.
Handel, Joseph J. Sweeney, Patrick Crom, Vice President, Global Controller and
Chief Accounting Officer of Applied Materials, Stephen Cooper, Russell Wayman,
William Cole, Vice President of Sales and Service for Etec, William Snyder,
Paul Warkantin, Senior Vice President, Advanced Reticle Solutions Center for
Etec, and William Ryan, a member of Etec's board of directors. Representatives
from Morgan Stanley and Goldman Sachs also attended the due diligence meeting.

   On January 10, 2000, Kalman Kaufman, Joseph R. Bronson and Joseph J. Sweeney
discussed the proposed transaction with certain members of Applied Materials'
board of directors.

   On January 11, 2000, certain members of the Applied Materials board of
directors held a conference call with members of Applied Materials' senior
management to discuss the proposed terms of the merger agreement and evaluate
the strategic opportunities presented by the proposed merger. These members of
the Applied Materials' board of directors inquired as to the results of the due
diligence efforts and the potential benefits and risks to Applied Materials of
the proposed merger.

   On January 12, 2000, the Etec board of directors met again by telephone
conference call to discuss the proposed merger. At the meeting, Goldman Sachs
updated its financial review with respect to the proposed merger, and the board
of directors, members of Etec management and representatives of Etec's outside
legal counsel and financial advisor discussed the terms of the merger agreement
and related agreements. At the conclusion of the financial review and
discussion of the terms of the merger agreement and related agreements, Goldman
Sachs provided the Etec board of directors with its oral opinion (subsequently
confirmed in writing) that as of that date and based upon certain assumptions
and qualifications, the exchange ratio in the merger agreement was fair to the
holders of Etec common stock from a financial point of view. After discussion,
the Etec board of directors unanimously approved the merger agreement, the
related agreements, including the stock option agreement and the transactions
contemplated by the merger agreement and the related agreements, subject to
successful completion of negotiations, and authorized the officers of Etec to
finalize and execute the merger agreement and related agreements.


                                       36
<PAGE>

   Also on January 12, 2000, the Applied Materials board of directors held a
special meeting by telephone conference call to review the principal terms of
the proposed merger, the strategic rationale therefor, and Etec's business. At
the meeting, Morgan Stanley, Applied Materials' financial advisor, presented a
summary of its analysis of the transaction; and a representative of Applied
Materials' outside legal counsel, Cooley Godward, discussed legal aspects of
the merger, deal terms on which negotiations were continuing and related
issues. After the discussion, the directors attending the meeting voted
unanimously to approve the proposed merger, the merger agreement and the
related agreements, including the stock option agreement and the transactions
contemplated by the merger agreement and the related agreements, subject to
successful completion of negotiations, and authorized the officers of Applied
Materials to complete negotiations and finalize and execute the merger
agreement and related agreements.

   On January 12, 2000, upon completion of all negotiations and finalization of
all agreements, the two companies executed and delivered the merger agreement
and related agreements, and Applied Materials and Etec issued a joint press
release announcing the transaction.

Reasons for the Merger

   The following discussion of the parties' reasons for the merger contains a
number of forward-looking statements that reflect the current views of Applied
Materials and/or Etec with respect to future events that may have an effect on
their future financial performance. Forward-looking statements are subject to
risks and uncertainties. Actual results and outcomes may differ materially from
the results and outcomes discussed in the forward-looking statements.
Cautionary statements that identify important factors that could cause or
contribute to differences in results and outcomes include those discussed in
"Summary--Forward Looking Information" and "Risk Factors."

Applied Materials' Reasons for the Merger

   Applied Materials' primary reasons for seeking to consummate a business
combination with Etec are the beliefs of the Applied Materials board of
directors and management that a business combination could result in a number
of benefits, including:

  . the ability of the combined company to offer complementary product lines
    and improve product offerings;

  . the ability of the two companies to combine their technological resources
    to develop new products with increased functionality and bring them to
    market faster;

  . the strategic benefits of the ability of the combined company to commit
    greater resources to both current and emerging product development
    efforts and fund the future growth of its business;

  . entry into a new strategic market segment for Applied Materials, with the
    potential for above average growth through an established market leader;
    and

  . Etec's critical technologies and significant technical, engineering,
    management and sales expertise, which is in high demand and short supply.

     The Applied Materials board of directors has determined that the merger
  is in the best interests of Applied Materials. In reaching its
  determination, the Applied Materials board of directors considered a number
  of factors, including the factors discussed above and listed below. The
  conclusions reached by the Applied Materials board of directors with
  respect to each of these factors supported its determination that the
  merger and the issuance of shares of Applied Materials common stock in the
  merger were fair to, and in the best interests of, Applied Materials:

  . the judgment, advice and analyses of Applied Materials' management with
    respect to the potential strategic, financial and operational benefits of
    the merger, including Applied Materials management's

                                       37
<PAGE>

   favorable recommendation of the merger, based in part on the business,
   technical, financial, accounting and legal due diligence investigations
   performed with respect to Etec;

  . the results of operations and financial condition of Applied Materials
    and Etec and the anticipated accretive effect of the combination on
    Applied Materials common stock;

  . the complementary fit between Applied Materials' and Etec's cultures and
    market segments, which should facilitate integration of the two
    companies;

  . the terms of the merger agreement and related agreements, including price
    and structure, which were considered by both the board of directors and
    management of Applied Materials to provide a fair and equitable basis for
    the merger; and

  . the ability to effect the merger as a pooling of interests for financial
    accounting purposes.
   The Applied Materials board of directors also considered a number of
potentially negative factors in its deliberations concerning the merger. The
negative factors considered by the Applied Materials board of directors
included:

  . the risk that the merger might not be completed in a timely manner or at
    all;

  . the negative impact of any customer or supplier confusion after
    announcement of the proposed merger;

  . the potential dilutive effect on Applied Materials common stock price if
    revenue and earnings expectations of the combined company are not met;

  . the potential loss of key Etec employees critical to the ongoing success
    of the Etec products and to the successful integration of the Applied
    Materials and Etec product lines;

  . the lower rates of Etec's revenue and earnings growth relative to Applied
    Materials' revenues and earnings growth over the last two fiscal years;

  . the general difficulties of integrating products, technologies and
    companies;

  . the possibility of cultural conflicts between the two companies; and

  . the other risks and uncertainties discussed above under "Risk Factors."

   The foregoing discussion of information and factors considered by the
Applied Materials board of directors is not intended to be exhaustive but is
believed to include all material factors considered by the Applied Materials
board of directors. In view of the wide variety of factors considered by the
Applied Materials board of directors, the Applied Materials board of directors
did not find it practicable to quantify or otherwise assign relative weight to
the specific factors considered. In addition, the Applied Materials board did
not reach any specific conclusion on each factor considered, or any aspect of
any particular factor, but conducted an overall analysis of these factors.
Individual members of the Applied Materials board may have given different
weight to different factors. However, after taking into account all of the
factors set forth above, the Applied Materials board of directors unanimously
agreed that the merger agreement and the merger were fair to, and in the best
interests of, Applied Materials and that Applied Materials should proceed with
the merger.

Etec's Reasons for the Merger

   The Etec board of directors believes that, despite Etec's success to date,
increasing competition and industry consolidation would make it increasingly
important for Etec to grow and gain critical mass in order to compete with
larger companies with substantially greater resources and broader, integrated
product offerings. Etec's management has considered a number of alternatives
for enhancing its competitive position, including by growing through the
acquisition of smaller companies that could extend Etec's product offerings
and enhance the distribution of Etec's products and services, or merging with
a larger company. In the industry

                                      38
<PAGE>

environment referred to above, the Etec board of directors identified several
potential benefits for the Etec stockholders, employees and customers that it
believes would result from the merger. These potential benefits include:

  . providing Etec stockholders with shares of Applied Materials common stock
    in a tax-free exchange at a substantial premium over the prevailing
    market price for Etec common stock immediately prior to the announcement
    of the merger;

  . mitigating of the risk of large changes in Etec's stock price due to
    significant variations in Etec's shipments from quarter to quarter;

  . dampening the magnitude of swings in operating results based on different
    demand cycles for the two companies' products;

  . the availability of greater resources for product distribution and
    service; and

  . the ability of the combined company to offer complementary product lines,
    which presents the opportunity to increase the breadth of products
    offered.

   The board of directors of Etec believes that the exchange ratio will result
in a significant financial premium to the Etec stockholders. Although the
specific amount of the premium depends on the value of Applied Materials stock
and Etec stock on the closing date, based upon the closing price of Applied
Materials common stock on January 12, 2000 of $127.06, the transaction implied
a $82.46 share price for Etec, representing a premium of 65% to Etec's closing
price on January 12, 2000 and a premium of 89% to Etec's average share price
for the 30 days ending January 12, 2000.

   Historically, one of the greatest risks to Etec stockholders has been the
extreme quarter-to-quarter fluctuations in operating results. Etec sells only a
relatively small number of units of product in any reporting period, and
various events can cause an increase or decrease by one or two units in the
number of units for which revenue is recognized in any quarter. Events causing
a shortfall in units sold during a particular quarter may include a general
downturn in the semiconductor chip or semiconductor equipment industry, a delay
in acceptance of a unit by a customer for technical reasons, or other special
circumstances. Such variations of a few units can cause relatively large swings
in reported operating results, and make the Etec stock price inherently more
volatile and unpredictable than other companies that sell a much larger number
of units at lower average selling prices in a quarter. The board of directors
of Etec believes that a merger with Applied Materials, a much larger
corporation, will significantly mitigate the effects of variations in Etec's
revenue pattern.

   Applied Materials is also a participant in the semiconductor chip market.
The whole market for the semiconductor chip industry is subject to cyclicality
of demand as worldwide demand for semiconductor chips may grow more or less
quickly or suffer a downturn. However, the demand cycles for Etec's maskmaking
equipment have historically occurred at a different time than the demand cycles
for Applied Materials' products and semiconductor chips in general. Many units
of Etec equipment are purchased to support front-end semiconductor chip
development work, while most Applied Materials equipment is purchased to
support volume semiconductor chip manufacturing. The board of directors of Etec
believes that the combination of two companies with cycles that are offset in
time should serve to dampen the magnitude of swings in Etec's operating
results.

   In the course of its deliberations during the Etec board of directors
meetings, the Etec board of directors reviewed with Etec's management and
outside advisors a number of factors relevant to the merger, including the
strategic overview and prospects for Etec. The Etec board of directors also
considered the following positive factors, among others, in connection with its
review and analysis of the merger. The conclusions reached by the Etec board of
directors with respect to each of these factors supported its determination
that the merger agreement and the completion of the merger were fair to, and in
the best interests of, Etec and its stockholders:

  . historical information concerning Applied Materials' and Etec's
    respective businesses, financial performance and condition, operations,
    technology, management and competitive position;

                                       39
<PAGE>

  . Etec management's view as to the financial condition, results of
    operations and businesses of Applied Materials and Etec before and after
    giving effect to the merger based on management due diligence and
    publicly available earnings estimates and, in particular, the view that,
    in light of, among other things, market and industry conditions, the
    potential synergy and compatibility between Etec and Applied Materials,
    the financial strength of Applied Materials and the ability to leverage
    Applied Materials' sales network to increase sales of Etec's products,
    the long-term financial condition, results of operations, prospects and
    competitive position of the combined company would be better than the
    long-term financial condition, results of operations, prospects and
    competitive position of Etec on a stand-alone basis;

  . current financial market conditions and historical market prices,
    volatility and trading information with respect to Applied Materials
    common stock and Etec common stock, which supported a favorable view of
    Applied Materials' stock market presence and positive reputation with
    investors, as well as the greater liquidity to Etec stockholders of an
    investment in Applied Materials common stock compared to Etec common
    stock;

  . the belief that the terms of the merger agreement, including the parties'
    representations, warranties and covenants, and the conditions to the
    parties' respective obligations, are reasonable;

  . the analyses prepared by Goldman Sachs and presented to the Etec board of
    directors on January 12, 2000, and the oral opinion of Goldman Sachs,
    subsequently confirmed in writing, that as of January 12, 2000 and based
    upon and subject to certain considerations set forth in Goldman Sachs'
    opinion (the full text of which is attached as Annex B to this proxy
    statement/prospectus), the exchange ratio was fair, from a financial
    point of view, to the holders of Etec common stock, as described more
    fully under "Opinion of Etec's Financial Advisor";

  . the impact of the merger on Etec's customers and employees; and

  . reports from management, legal advisors and financial advisors as to the
    results of their due diligence investigation of Applied Materials.

   The Etec board of directors also considered a number of potentially negative
factors in its deliberations concerning the merger. The negative factors
considered by the Etec board of directors included:

  . the risk that, because the exchange ratio will not be adjusted for
    changes in the market price of either Applied Materials common stock or
    Etec common stock, the per share value of the consideration to be
    received by Etec stockholders might be less than the price per share
    implied by the exchange ratio immediately before the announcement of the
    merger due to fluctuations in the market value of Applied Materials
    common stock and Etec common stock;

  . the risk that the merger might not be completed in a timely manner or at
    all;

  . the negative impact of any customer or supplier confusion after
    announcement of the proposed merger;

  . the challenges relating to the integration of the two companies;

  . the loss of control over the future operations of Etec following the
    merger;

  . the possibility of management and employee disruption associated with the
    potential merger and integrating the operations of the companies, and the
    risk that, despite the efforts of the combined company, key management,
    marketing, technical and administrative personnel of Etec might not
    continue with the combined company;

  . certain terms of the merger agreement and related agreements that
    prohibit Etec and its representatives from soliciting third party bids
    and from accepting, approving or recommending unsolicited third party
    bids except in very limited circumstances, which terms would reduce the
    likelihood that a third party would make a bid for Etec;

  . the termination fee payable by Etec in certain circumstances (see
    "Expenses and Termination Fee");

                                       40
<PAGE>

  . the negative impact of the stock option agreement on Etec's ability to
    attract a higher bid from a third party, particularly in light of the
    fact that if the option becomes exercisable, an acquisition of Etec by a
    third party cannot be accounted for as a "pooling of interests";

  . the risks relating to Applied Materials' business and how they would
    affect the operations of the combined company; and

  . the other risks described above under "Risk Factors."

   Etec's board of directors believed that these risks were outweighed by the
potential benefits of the merger.

   The foregoing discussion of information and factors considered by the Etec
board of directors is not intended to be exhaustive but is believed to include
all material factors considered by the Etec board of directors. In view of the
wide variety of factors considered by the Etec board of directors, the Etec
board of directors did not find it practicable to quantify or otherwise assign
relative weight to the specific factors considered. In addition, the Etec
board did not reach any specific conclusion on each factor considered, or any
aspect of any particular factor, but conducted an overall analysis of these
factors. Individual members of the Etec board may have given different weight
to different factors. However, after taking into account all of the factors
set forth above, the Etec board of directors unanimously agreed that the
merger agreement and the merger were fair to, and in the best interests of,
Etec and its stockholders and that Etec should proceed with the merger.

Opinion of Etec's Financial Advisor

   On January 12, 2000, Goldman Sachs delivered its oral opinion, subsequently
confirmed in Goldman Sachs' written opinion dated January 12, 2000, to the
Etec board of directors that based upon and subject to certain considerations
described therein, as of such date, the exchange ratio of 0.649 a share of
Applied Materials common stock to be received for each share of Etec common
stock pursuant to the merger agreement was fair from a financial point of view
to the holders of shares of Etec common stock.

   The full text of the written opinion of Goldman Sachs, dated January 12,
2000, which sets forth, among other things, assumptions made, matters
considered and limitations on the review undertaken in connection with the
opinion, is attached hereto as Annex B and is incorporated herein by
reference. THE SUMMARY OF GOLDMAN SACHS' FAIRNESS OPINION SET FORTH BELOW IS
QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT OF ITS FAIRNESS
OPINION ATTACHED TO THIS PROXY STATEMENT/PROSPECTUS AS ANNEX B. ETEC
STOCKHOLDERS ARE URGED TO, AND SHOULD, READ CAREFULLY THE OPINION IN ITS
ENTIRETY.

   In connection with its opinion, Goldman Sachs reviewed, among other things:

  . the merger agreement;

  . the Annual Reports to Stockholders and Annual Reports on Form 10-K of:
    (a) Etec for the four fiscal years ended July 31, 1999; and (b) Applied
    Materials for the five fiscal years ended October 31, 1998;

  . certain interim reports to stockholders and Quarterly Reports on Form 10-
    Q of both Etec and Applied Materials;

  . certain other communications from Etec and Applied Materials to their
    respective stockholders; and

  . certain internal financial analyses and forecasts for Etec prepared by
    its management.

   Goldman Sachs relied upon the accuracy and completeness of all of the
financial and other information discussed with or reviewed by it and assumed
such accuracy and completeness for purposes of rendering this opinion. Goldman
Sachs' review of the projections of expected future financial performance of
Applied Materials was limited to discussions with members of the senior
management of Applied Materials regarding

                                      41
<PAGE>

certain research analyst estimates for Applied Materials. In addition, Goldman
Sachs did not make an independent evaluation or appraisal of the assets and
liabilities of Etec or Applied Materials or any of their subsidiaries and was
not furnished with any such evaluation or appraisal. Goldman Sachs was not
requested to solicit, and did not solicit, interest from other parties with
respect to an acquisition of or other business combination with Etec. Goldman
Sachs also took into account Etec's expectations regarding the accounting
treatment of the transaction. Goldman Sachs' opinion was provided for the
information and assistance of the board of directors of Etec in connection with
its consideration of the transaction contemplated by the merger agreement and
its opinion does not constitute a recommendation as to how any holder of Etec
shares of common stock should vote with respect to such transaction.

   Goldman Sachs also held discussions with members of the senior management of
Etec and Applied Materials regarding their assessment of the strategic
rationale for, and the potential benefits of, the transaction contemplated by
the merger agreement and the past and current business operations, financial
condition and future prospects of Etec and Applied Materials, respectively. In
addition, Goldman Sachs reviewed the reported price and trading activity for
the Etec common stock and the Applied Materials common stock, compared certain
financial and stock market information for Etec and Applied Materials with
similar information for other companies the securities of which are publicly
traded, reviewed the financial terms of certain recent business combinations in
the semiconductor equipment industry specifically and in other industries
generally and performed such other studies and analyses as it considered
appropriate.

   The following is a summary of certain of the financial analyses used by
Goldman Sachs in connection with providing its opinion to the Etec board of
directors.

 Exchange Ratio History

   Goldman Sachs reviewed the implied market exchange ratio for shares of Etec
common stock and Applied Materials common stock, determined by dividing the per
share closing price for Etec's common stock by the per share closing price for
Applied Materials' common stock for each day during the period. The implied
average market exchange ratio for the 90 trading day and the 60 trading day
periods ending January 12, 2000 were 0.41 and 0.39, respectively. The implied
average market exchange ratio for both the 30 trading day and the 10 trading
day period ending January 12, 2000 was 0.37. The implied market exchange ratio
based on closing prices on January 12, 2000 was 0.39.

 Comparison of Selected Semiconductor Capital Equipment Companies

   Goldman Sachs reviewed and compared selected stock price and financial
information relating to Etec to corresponding financial information for the
following three groups of semiconductor capital equipment companies:

 Other Considerations

   The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to partial analysis or summary description. Selecting
portions of the analyses or of the summary set forth above, without considering
the analyses as a whole, may create an incomplete view of the processes
underlying Goldman Sachs' opinion. In arriving at its fairness determination,
Goldman Sachs considered the results of all such analyses. No company or
transaction used in the above analyses as a comparison is directly comparable
to Etec, Applied Materials or the merger.

   The analyses were prepared solely for purposes of Goldman Sachs providing
its opinion to the Etec board of directors as to the fairness from a financial
point of view of the merger consideration and do not purport to be appraisals
or necessarily reflect the prices at which the business or securities actually
may be sold. Analyses based upon forecasts of future results are not
necessarily indicative of actual future results, which may be significantly
more or less favorable than suggested by such analyses. Because such analyses
are inherently subject to uncertainty, being based upon numerous factors or
events beyond the control of the parties or their respective advisors, none of
Etec, Applied Materials, Goldman Sachs or any other person assumes
responsibility if future results are materially different from those forecast.
As described above, Goldman Sachs' opinion to the Etec board of directors was
one of many factors taken into consideration by the Etec board of

                                       44
<PAGE>

directors in making its determination to approve the merger agreement. The
foregoing summary describes material financial analyses used by Goldman Sachs
in connection with providing its opinion to the Etec Sytems' board of directors
on January 12, 2000, but does not purport to be a complete description of the
analysis performed by Goldman Sachs in connection with such opinion and is
qualified by reference to the written opinion of Goldman Sachs set forth in
Annex B hereto.

   Goldman Sachs, as part of its investment banking business, is continually
engaged in the valuation of businesses and their securities in connection with
mergers and acquisitions, negotiated underwritings, competitive biddings,
secondary distributions of listed and unlisted securities, private placements,
and valuations for estate, corporate and other purposes. Goldman Sachs is
familiar with Etec, having acted as its financial advisor in connection with,
and having participated in certain of the negotiations leading to, the merger
agreement. Etec selected Goldman Sachs as its financial advisor because it is a
nationally recognized investment banking firm that has substantial experience
in transactions similar to the merger. Goldman Sachs has also provided services
to Applied Materials from time to time, having acted as managing underwriter in
connection with the October 1997 public offering by Applied Materials of $200
million aggregate principal amount of 6.75% Notes due 2007 and $200 million
aggregate principal amounts of 7.125% Notes due 2017. Goldman Sachs provides a
full range of financial advisory and securities services and, in the course of
its normal trading activities, may from time to time effect transactions and
hold securities, including derivative securities, of Etec or Applied Materials
for its own account and for the accounts of customers.

   Pursuant to a letter agreement dated October 1, 1999, Etec engaged Goldman
Sachs to act as its financial advisor in connection with a potential
transaction involving Applied Materials. Pursuant to the terms of this
engagement letter, Goldman Sachs will receive a customary fee, a substantial
portion of which is contingent on the closing of the merger. Etec has also
agreed to reimburse Goldman Sachs for its reasonable out-of-pocket expenses,
including attorneys' fees and disbursements plus any sales, use or similar
taxes, and to indemnify Goldman Sachs against certain liabilities, including
certain liabilities under the federal securities laws.

Interests of Etec's Officers and Directors in the Merger

   In considering the recommendation of the Etec board of directors with
respect to approving the merger agreement, Etec stockholders should be aware
that certain members of the board of directors and management of Etec have
interests in the merger that are in addition to the interests of stockholders
of Etec generally. The Etec board of directors was aware of these interests and
considered them, among other matters, in approving the merger agreement.

   Indemnification and Insurance. The merger agreement provides for the
survival after the merger of all indemnification rights of the directors and
officers of Etec for acts and omissions occurring before the merger, as their
rights existed as of January 12, 2000, in the Etec bylaws and in
indemnification agreements with Etec. Applied Materials has agreed to guarantee
that the surviving company observes its commitments under these indemnification
agreements. In addition, for a period of six years after the closing of the
merger, the surviving corporation will maintain in effect the existing policy
of directors' and officers' liability insurance policy maintained by Etec or
substitute for the current policy, a policy or policies with comparable
coverage. If the annual premiums of such insurance coverage exceed $475,000 in
the aggregate, the surviving corporation may reduce the amount of coverage to
the amount of coverage that can be obtained for an annual premium equal to
$475,000.

   1995 Omnibus Incentive Plan Acceleration. All unvested options under the
Etec 1995 Omnibus Incentive Plan which are held by an officer who holds a
position with the rank of Vice President or higher will become exercisable (i)
immediately before the completion of a change in control of Etec if any such
officer is not offered employment with the surviving company in such change of
control or (ii) upon termination without cause or constructive termination of
such officer's employment following a change in control of Etec. The merger is
a change in control for this purpose. If we assumed that the merger was
completed on January 12,

                                       45
<PAGE>

2000, options to purchase a total of 1,507,643 shares of Etec common stock held
by 16 individuals with the rank of Vice President or above would become
exercisable in full if these individuals' option vesting acceleration
provisions were triggered on such date.

Material Federal Income Tax Consequences

   The following discussion summarizes the material U.S. federal income tax
considerations of the merger that are expected to apply generally to Etec
stockholders upon an exchange of their Etec common stock for Applied Materials
common stock in the merger. This summary is based upon current provisions of
the Internal Revenue Code, existing regulations under the Internal Revenue Code
and current administrative rulings and court decisions, all of which are
subject to change. Any change, which may or may not be retroactive, could alter
the tax consequences to Applied Materials, Etec or the stockholders of Etec as
described in this summary. No attempt has been made to comment on all federal
income tax consequences of the merger that may be relevant to particular
holders, including holders:

  . who are subject to special tax rules, such as dealers in securities,
    foreign persons, mutual funds, insurance companies and tax-exempt
    entities;

  . who are subject to the alternative minimum tax provisions of the Internal
    Revenue Code;

  . who acquired their shares in connection with stock option or stock
    purchase plans or in other compensatory transactions;

  . who hold their shares as a hedge or as part of a hedging, straddle or
    other risk reduction strategy; or

  . who do not hold their shares as capital assets.

   In addition, the following discussion does not address the tax consequences
of the merger under state, local and foreign tax laws. Furthermore, the
following discussion does not address (i) the tax consequences of transactions
effectuated before, after or at the same time as the merger, whether or not
they are in connection with the merger, including, without limitation,
transactions in which Etec shares are acquired or Applied Materials shares are
disposed of, (ii) the tax consequences to holders of options issued by Etec
that are assumed, exercised or converted, as the case may be, in connection
with the merger, (iii) the tax consequences of the receipt of Applied Materials
shares other than in exchange for Etec shares, or (iv) the tax implications of
a failure of the merger to qualify as a reorganization. Accordingly, holders of
Etec common stock are advised and expected to consult their own tax advisors
regarding the federal income tax consequences of the merger in light of their
personal circumstances and the consequences under state, local and foreign tax
laws.

   Pursuant to the terms of the merger agreement, Cooley Godward LLP and Wilson
Sonsini Goodrich & Rosati, Professional Corporation have rendered tax opinions
that the merger will constitute a reorganization within the meaning of Section
368(a) of the Internal Revenue Code (a "Reorganization"). The tax opinions
discussed in this section assume and are conditioned upon the following:

  . the truth and accuracy of the statements, covenants, representations and
    warranties contained in the merger agreement, in the tax representations
    received from Applied Materials, Merger Sub and Etec to support the tax
    opinions and in all other instruments and documents related to the
    formation, organization and operation of Applied Materials, Merger Sub
    and Etec examined by and relied upon by Cooley Godward LLP and Wilson
    Sonsini Goodrich & Rosati, Professional Corporation in connection with
    the merger;

  . that original documents submitted to such counsel are authentic, that
    documents submitted to such counsel as copies conform to the original
    documents and that all of these documents have been (or will be by the
    effective time) duly and validly executed and delivered where due
    execution and delivery are a prerequisite to the effectiveness of these
    documents;

  . that all covenants contained in the merger agreement and the tax
    representations described above are performed without waiver or breach of
    any material provision of these covenants; and

                                       46
<PAGE>

  . that any representation or statement made "to the best of knowledge" or
    similarly qualified is correct without that qualification.

   No ruling from the Internal Revenue Service has been or will be requested in
connection with the merger. In addition, stockholders of Etec should be aware
that the tax opinions discussed in this section are not binding on the IRS; the
IRS could adopt a contrary position and a contrary position could be sustained
by a court.

   Subject to the assumptions and limitations discussed above, it is the
opinion of Cooley Godward LLP, tax counsel to Applied Materials and Wilson
Sonsini Goodrich & Rosati, Professional Corporation, tax counsel to Etec, that:

  . the merger will be treated for federal income tax purposes as a
    Reorganization;

  . Applied Materials, Merger Sub and Etec will each be a party to the
    Reorganization;

  . Applied Materials, Merger Sub and Etec will not recognize any gain or
    loss solely as a result of the merger;

  . stockholders of Etec will not recognize any gain or loss upon the receipt
    of solely Applied Materials common stock for their Etec common stock;

  . the aggregate basis of the shares of Applied Materials common stock
    received by an Etec stockholder in the merger (including any fractional
    share deemed received) will be the same as the aggregate basis of the
    shares of Etec common stock surrendered in exchange therefor;

  . the holding period of the shares of Applied Materials common stock
    received by an Etec stockholder in the merger will include the holding
    period of the shares of Etec common stock surrendered in exchange
    therefor, provided that such shares of Etec common stock are held as
    capital assets at the effective time of the merger; and

  . a stockholder of Etec who receives cash in lieu of a fractional share
    will recognize gain or loss equal to the difference, if any, between such
    stockholder's basis in the fractional share and the amount of cash
    received. Such gain or loss will be a capital gain or loss if the Etec
    common stock is held by such stockholder as a capital asset at the
    effective time of the merger.

Anticipated Accounting Treatment

   The merger is expected to be accounted for using the "pooling of interests"
method of accounting pursuant to Opinion No. 16 of the Accounting Principles
Board. The pooling of interests method of accounting assumes that the combining
companies have been merged from inception, and the historical consolidated
financial statements for periods prior to completion of the merger are restated
as though the companies had been combined from inception. Applied Materials may
terminate the merger agreement if the merger cannot be accounted for as a
pooling of interests.

Regulatory Approvals

   Under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 and the rules
promulgated thereunder (the "HSR Act"), the merger may not be completed until
notifications have been given and certain information has been furnished to the
Federal Trade Commission (the "FTC") and the Antitrust Division of the U.S.
Department of Justice and specified waiting period requirements have been
satisfied or early termination of the waiting period is granted at the request
of Applied Materials and Etec. Applied Materials and Etec filed notification
and report forms under the HSR Act with the FTC and the Antitrust Division on
January 24, 2000. These filings commenced a 30-day waiting period under the HSR
Act. If, prior to the expiration of this period, the FTC or the Antitrust
Division should request additional information or documentary material under
the HSR Act, completion of the merger could be delayed until after the
companies have substantially complied with the request.


                                       47

   Under the German anticompetition law and the rules promulgated thereunder
("German Law"), the merger may not be completed until notification has been
given and certain information has been furnished to the Federal Cartel Office
(the "FCO") and specified waiting period requirements have been satisfied.
Applied Materials and Etec filed notification and report forms under German Law
with the FCO in February 2000. These filings commenced a 30-day waiting period
under German Law. If, prior to the expiration of such period, the FCO should
request additional information or documentary material under German Law,
completion of the merger could be delayed.

   There can be no assurance that a challenge to the merger on antitrust
grounds will not be made, or if such challenge is made, that Applied Materials
and Etec would prevail or would not be required to terminate the merger
agreement, to divest certain assets, to license certain proprietary technology
to third parties or to accept certain conditions in order to complete the
merger.

Restrictions on Resale by Affiliates

   The shares of Applied Materials common stock to be received by Etec
stockholders in the merger have been registered under the Securities Act and,
except as described in this paragraph, may be freely traded without
restriction. The shares of Applied Materials common stock to be issued in the
merger and received by persons who are considered to be "affiliates" (as that
term is used in Rule 145 under the Securities Act) of Etec before the merger
may be resold by them only in transactions permitted by the resale provisions
of Rule 145 under the Securities Act or as otherwise permitted under the
Securities Act. Under guidelines published by the SEC, the sale or other
disposition of Applied Materials common stock or Etec common stock by an
affiliate of either Applied Materials or Etec within 30 days before the
effective time of the merger or the sale or other disposition of Applied
Materials common stock after the merger and before the publication of financial
results that include at least 30 days of post-merger combined operations of
Applied Materials and Etec could preclude pooling of interests accounting
treatment of the merger. Accordingly, Applied Materials has obtained signed
affiliate agreements from all persons whom it has been advised may be
considered to be affiliates of Etec. The affiliate agreements provide that
these persons will not sell, transfer or otherwise dispose of any shares of
Etec common stock or Applied Materials common stock during the period referred
to above and that they will not sell, transfer or otherwise dispose of Applied
Materials common stock at any time in violation of the Securities Act,
including Rule 145.

                     CERTAIN TERMS OF THE MERGER AGREEMENT

   The following description of the merger agreement describes the material
terms of the merger agreement. The full text of the merger agreement is
attached as Annex A to this proxy statement/prospectus and is incorporated in
this proxy statement/prospectus by reference. We encourage you to read the
entire merger agreement carefully.

The Merger

   The merger agreement provides that at the effective time of the merger,
Merger Sub will be merged with and into Etec. Upon completion of the merger,
Etec will continue as the surviving corporation and will be a wholly-owned
subsidiary of Applied Materials.

Effective Time of the Merger

   The merger will become effective when articles of merger executed by both
Etec and Merger Sub are filed with the Nevada Secretary of State. If all the
conditions to the merger contained in the merger agreement are satisfied or
waived, we anticipate that the effective time will occur on the date of the
special meeting of Etec stockholders or as soon as practicable following the
special meeting.

Manner and Basis of Converting Shares

   At the effective time, each share of Etec common stock will automatically be
converted into the right to receive 0.649 of a share of Applied Materials
common stock. No fractional shares of Applied Materials common stock will be
issued in the merger. Instead, each Etec stockholder entitled to a fractional
share will receive a cash amount (rounded to the nearest whole cent), without
interest, based on the closing price of Applied Materials common stock on the
Nasdaq National Market on the date the merger becomes effective.

   Following the effective time, Harris Trust Company of New York, which has
been selected by Applied Materials to act as exchange agent, will mail to each
record holder of Etec common stock immediately before the effective time, a
letter indicating that the merger has been completed. Record holders of Etec
common stock will also be mailed a transmittal letter, which record holders
will use to exchange Etec common stock certificates for Applied Materials
common stock certificates and cash for any fractional share. Transmittal
letters will also be available following completion of the merger at the
offices of the exchange agent at Wall Street Station, P.O. Box 1010, New York,
NY 10268-1010. Additionally, holders of Etec common stock certificates may, at
their option after the effective time, physically surrender in person at the
offices of the exchange agent their certificates for certificates evidencing
Applied Materials common stock and cash for any fractional share. Etec common
stock certificates should not be surrendered for exchange by Etec stockholders
before the effective time. After the effective time, transfers of Etec common
stock will not be registered on the stock transfer books of Etec.

   After the effective time, until it is surrendered and exchanged, each
certificate that previously evidenced Etec common stock will be deemed to
evidence the right to receive shares of Applied Materials common stock and the
right to receive cash instead of any fractional share. Applied Materials will
not pay dividends or other distributions on any shares of Applied Materials
common stock to be issued in exchange for any Etec common stock certificate
that is not surrendered until the Etec common stock certificate is surrendered
as provided in the merger agreement.

Etec Stock Options and Warrants

   At the effective time, Applied Materials will assume all outstanding Etec
stock options (other than options granted under Etec's 1995 Employee Stock
Purchase Plan) and warrants. Each outstanding stock option or warrant assumed
by Applied Materials will become an option or warrant to purchase a number of
shares of

                                       49
<PAGE>

Applied Materials common stock determined by multiplying the number of shares
of Etec common stock subject to the stock option or warrant immediately before
the effective time by the exchange ratio, rounding down to the nearest whole
share. The exercise price per share of Applied Materials common stock subject
to each assumed stock option or warrant will be equal to the exercise price per
share of the Etec common stock subject to the stock option or warrant divided
by the exchange ratio, rounding up to the nearest cent. All other terms and
conditions of the stock options and warrants will not change and will operate
in accordance with their terms.

   Instead of assuming outstanding Etec stock options and warrants, Applied
Materials has the right, under the terms of the merger agreement, to replace
outstanding Etec stock options and warrants with substitute options and
warrants to purchase shares of Applied Materials common stock. If Applied
Materials decides to substitute options and warrants, the number of shares
covered by the substituted options and warrants and the exercise price of the
substituted options and warrants will be calculated as described in the
preceding paragraph. All other terms of the substitute options and warrants
will be no more or less favorable to the optionee or warrantholder than the
terms of the options and warrants they are replacing.

   Based on the stock options and warrants of Etec outstanding at the record
date and assuming no such stock options or warrants are exercised before the
effective time, Applied Materials will be required at the effective time to
reserve approximately [          ] shares of Applied Materials common stock for
issuance upon exercise of Etec stock options and warrants assumed or
substituted by Applied Materials in connection with the merger.

Etec Employee Stock Purchase Plan

   Etec's 1995 Employee Stock Purchase Plan will be terminated at the effective
time. The last business day before the effective time will be treated as the
last day of the offering periods then underway under the Employee Stock
Purchase Plan. Pro-rata adjustments may be required under the Employee Stock
Purchase Plan to reflect this shortened offering period, but the offering
period will otherwise be treated as a fully effective and completed offering
period for all purposes of the Employee Stock Purchase Plan. The change in the
offering period described above is conditioned upon the completion of the
merger.

Representations and Warranties

   The merger agreement contains customary representations and warranties of
Etec and Applied Materials relating to, among other things, certain aspects of
the respective businesses and assets of the parties and other matters. The
representations and warranties expire at the effective time.

Covenants; Conduct of Business Prior to the Merger

   Affirmative Covenants of Etec. Etec has agreed that before the effective
time it will, among other things, and subject to specified exceptions:

  .  conduct its business and operations only in the ordinary course and in
     accordance with past practices, use all reasonable efforts to preserve
     intact its current business organization, keep available the services of
     its current officers and employees and maintain its relations and
     goodwill with all suppliers, customers, landlords, creditors, licensors,
     licensees, employees and other persons having business relationships
     with it, keep in full force all insurance policies, provide all notices,
     assurances and support required pursuant to any contract relating to any
     of Etec's proprietary assets in order to ensure that there is no
     transfer or disclosure of any of Etec's source code, or a release from
     escrow of any of Etec's source code that has been previously deposited
     into escrow; and, to the extent requested by Applied Materials, cause
     its officers and the officers of its subsidiaries to report regularly to
     Applied Materials regarding the status of Etec's business;

                                       50
<PAGE>

  .  promptly notify Applied Materials of: (1) any communication from any
     person alleging that the consent of such person is required in
     connection with the transactions contemplated by the merger agreement;
     or (2) any legal proceeding commenced or threatened against or relating
     to Etec or any of its subsidiaries that relates to the completion of the
     transactions contemplated by the merger agreement;

  .  provide Applied Materials with access to Etec's personnel, assets,
     books, records, tax returns and other documents;

  .  deliver to Applied Materials copies of all material operating and
     financial reports prepared for Etec's senior management, any written
     materials sent by Etec to its stockholders, any material notice,
     document or other communication sent by Etec to or received by Etec from
     any party to a material contract and any notice, report or other
     document filed with or received from any governmental agency in
     connection with the merger;

  .  use all reasonable efforts to file all notices, reports and other
     documents required to be filed with any governmental agency with respect
     to the merger and the other transactions contemplated by the merger
     agreement, including the notifications required under the HSR Act and
     any applicable foreign antitrust laws or regulations in connection with
     the merger;

  .  use all reasonable efforts to take, or cause to be taken, all actions
     necessary to complete the merger and the other transactions contemplated
     by the merger agreement, including (i) making all filings and giving all
     notices, if any, required to be made and given by Etec in connection
     with the merger and the other transactions contemplated by the merger
     agreement, (ii) using all reasonable efforts to obtain each consent
     required to be obtained by Etec in connection with the merger or any of
     the other transactions contemplated by the merger agreement, and (iii)
     using all reasonable efforts to lift any restraint, injunction or other
     legal bar to the merger; and

  .  call and hold a meeting of its stockholders to vote on a proposal to
     approve the merger agreement.

   Etec has also agreed that its board of directors will recommend that the
Etec stockholders vote to approve the merger agreement. However, at any time
before the Etec special meeting, the Etec board of directors is entitled to
withdraw or modify its recommendation that the Etec stockholders vote to
approve the merger agreement if certain requirements, including the following,
are satisfied:

  .  an unsolicited, bona fide written offer to purchase all of the
     outstanding shares of Etec common stock is made to Etec and is not
     withdrawn;

  .  the Etec board of directors determines (i) based upon the advice of an
     independent financial advisor of nationally recognized reputation that
     the offer constitutes a superior offer and (ii) based upon the advice of
     its outside counsel, withdrawal or modification of its recommendation is
     required for the board of directors to comply with its fiduciary
     obligations to the Etec stockholders;

  .  the Etec board recommendation that the Etec stockholders vote to approve
     the merger agreement is not withdrawn or modified in a manner adverse to
     Applied Materials at any time within two business days after Applied
     Materials receives written notice from Etec confirming that Etec's board
     of directors has determined that the offer constitutes a superior offer;
     and

  .  neither Etec nor any of its representatives has violated the agreement
     not to solicit or encourage, or participate in discussions or
     negotiations with respect to, acquisition proposals from or with parties
     other than Applied Materials.

   For purposes of the merger agreement, the term "superior offer" means an
unsolicited, bona fide written offer made by a third party to purchase or
otherwise acquire (whether for cash, securities or other consideration and
whether by tender offer, merger or otherwise) 50% or more of the outstanding
shares of Etec common stock on terms that the Etec board of directors
determines, in its reasonable judgment, based upon a written opinion of an
independent financial advisor of nationally recognized reputation, to be more
favorable to the Etec stockholders than the merger and, if financing is
required, has committed financing or is reasonably capable of being financed.

                                       51
<PAGE>

   If the Etec board of directors withdraws or modifies its recommendation that
the Etec stockholders vote to approve the merger agreement, Etec may be
required to pay Applied Materials a fee in the amount of $54 million. See
"Expenses and Termination Fee."

   Negative Covenants of Etec. Etec has agreed that before the effective time,
except as otherwise agreed to in writing by Applied Materials, it will not,
will not agree to and will not permit any of its subsidiaries to:

     distribution in respect of any shares of capital stock, or repurchase,

     securities;

  .  subject to specified exceptions, sell, issue or grant any capital stock
     or any option, warrant or right to acquire any capital stock;

     evidencing any outstanding stock option or warrant;

  .  effect or become a party to any merger, consolidation, share exchange,
     business combination, recapitalization, reclassification of shares,
     stock split, reverse stock split, consolidation of shares or similar
     transaction;

  .  form any subsidiary or acquire any interest in any other entity;

  .  make any capital expenditure that, when added to all other capital
     expenditures made on behalf of Etec or its subsidiaries since January

     other than in the ordinary course of business consistent with past

  .  subject to specified exceptions, establish or amend any employee benefit
     plan, pay any bonus or make any profit-sharing payment to, or increase

     compensation payable to, any of its directors, officers or employees;

  .  hire any new employee at the level of Vice President or above or with an
     annual base salary in excess of $200,000, or promote any employee except
     in order to fill a position vacated after the date of the merger
     agreement;

  .  change any of its pricing policies, product return policies, product
     maintenance polices, service policies, product modification or upgrade
     policies, personnel policies or other business policies, or any of its

  .  take any action that Etec believes would preclude Applied Materials from
     accounting for the merger as a "pooling of interests";

  .  make any tax election;

  .  commence or settle any legal proceeding; or

  .  enter into any material transaction or take any other material action
     outside the ordinary course of business or inconsistent with past
     practices.

                                       52
<PAGE>

   Affirmative Covenants of Applied Materials. Applied Materials has agreed
that, before the effective time, it will, among other things, and subject to
specified exceptions:

  .  register under the Securities Act the issuance of the shares of Applied
     Materials common stock in the merger;

  .  use reasonable efforts to file all notices, reports and other documents
     required to be filed with any governmental agency with respect to the
     merger and the other transactions contemplated by the merger agreement,
     including the notifications required under the HSR Act and any
     applicable foreign antitrust laws or regulations in connection with the
     merger; and

  .  use all reasonable efforts to take, or cause to be taken, all actions
     necessary to complete the merger and the other transactions contemplated
     by the merger agreement, including (i) making all filings and giving all
     notices, if any, required to be made and given by Applied Materials in
     connection with the merger and the other transactions contemplated by
     the merger agreement, (ii) using all reasonable efforts to obtain each
     consent required to be obtained by Applied Materials in connection with
     the merger or any of the other transactions contemplated by the merger
     agreement, and (iii) using all reasonable efforts to lift any restraint,
     injunction or other legal bar to the merger.

   Applied Materials will not have any obligation under the merger agreement:
(i) to dispose of or transfer or cause any of its subsidiaries to dispose of or
transfer any assets, or to commit to cause Etec or any of Etec's subsidiaries
to dispose of any assets; (ii) to discontinue or cause any of its subsidiaries
to discontinue offering any product or service, or to commit to cause Etec or
any of Etec's subsidiaries to discontinue offering any product or service;
(iii) to license or otherwise make available, or cause or commit to cause any
of its subsidiaries or Etec or any of Etec's subsidiaries to license or
otherwise make available, to any person, any technology, software or other
proprietary asset; (iv) to hold separate or cause any of its subsidiaries to
hold separate any assets or operations (either before or after the completion
of the merger), or to commit to cause Etec or any of Etec's subsidiaries to
hold separate any assets or operations; (v) to make or cause any of its
subsidiaries to make any commitment (to any governmental body or otherwise)
regarding its future operations or the future operations of its subsidiaries;
or (vi) to contest any legal proceeding relating to the merger if Applied
Materials determines in good faith that contesting such legal proceeding might
not be advisable.

Limitation on Etec's Ability to Consider other Acquisition Proposals

   Etec has agreed that it will not, and that it will not authorize or permit
any of its subsidiaries or representatives to:

  .  solicit, initiate, encourage, induce or facilitate the making,
     submission or announcement of any offer, proposal, inquiry or indication
     of interest contemplating or otherwise relating to an Acquisition
     Transaction (as defined below) (an "Acquisition Proposal");

  .  furnish any information to any person in connection with or in response
     to an Acquisition Proposal or an inquiry or indication of interest that
     could lead to an Acquisition Proposal;

  .  engage in discussions or negotiations with any person with respect to
     any Acquisition Proposal;

  .  approve, endorse or recommend any Acquisition Proposal; or

  .  enter into any letter of intent or agreement contemplating or relating
     to any Acquisition Transaction.

   An "Acquisition Transaction" includes:

   1. any merger, consolidation, share exchange, business combination, issuance
of securities, acquisition of securities, recapitalization, tender offer,
exchange offer or other similar transaction (i) involving Etec or any of its
subsidiaries, (ii) in which a person or group of persons directly or indirectly
acquires ownership of securities representing more than 15% of the outstanding
securities of any class of voting securities of Etec or any of its subsidiaries
or (iii) in which Etec or any of its subsidiaries issues securities
representing more than 15% of the outstanding securities of any class of voting
securities of Etec or any of its subsidiaries;

                                       53
<PAGE>

   2. any sale, lease, exchange, transfer, license, acquisition or disposition
of any business or assets that account for 15% or more of the consolidated net
revenues or assets of Etec or any of its subsidiaries; or

   3. any liquidation or dissolution of Etec or any of its subsidiaries.

   However, these restrictions will not prohibit Etec from furnishing nonpublic
information to, or engaging in discussions or negotiations with, a third party
if it does so in response to a superior offer (defined above), which may be
conditioned on completion of "due diligence" by the third party, and if:

  .  neither Etec nor any of its representatives shall have violated any of
     the restrictions referred to in the preceding paragraph;

  .  the Etec board of directors, after having taken into account the advice
     of its outside legal counsel, concludes that the action is required in
     order for the board of directors to comply with its fiduciary
     obligations to the Etec stockholders;

  .  at least two business days prior to furnishing any nonpublic information
     to, or entering into discussions or negotiations with, the third party,
     Etec gives Applied Materials written notice of the identity of the third
     party and of Etec's intention to furnish nonpublic information to, or
     enter into discussions or negotiations with that third party and such
     information is furnished under a confidentiality agreement in
     substantially the same form as the mutual confidentiality agreement
     dated September 8, 1999 between Applied Materials and Etec; and

  .  prior to furnishing any nonpublic information to the third party, Etec
     provides the nonpublic information to Applied Materials.

   If the Etec board of directors receives an Acquisition Proposal, then Etec
must promptly inform Applied Materials of the terms of the proposal and the
identity of the person making it. Thereafter, Etec must promptly notify Applied
Materials of any material change in the terms of or status of the Acquisition
Proposal.

   Etec has agreed not to release any person from, or to waive any provision
of, any confidentiality, "standstill" or similar agreement to which it or any
of its subsidiaries is a party, and will use its best efforts to enforce or
cause to be enforced each of these agreements at the request of Applied
Materials. Etec has also agreed to promptly request each person that has
executed, within 12 months prior to the date of the merger agreement, a
confidentiality agreement in connection with its consideration of a possible
Acquisition Transaction or equity investment in Etec to return all confidential
information furnished to that person by or on behalf of Etec or any of its
subsidiaries.

Conditions to the Merger

   Conditions to the Obligations of Each Party. The obligations of Applied
Materials and Etec to complete the merger are subject to the satisfaction of
the following conditions:

  .  the registration statement on Form S-4 of which this proxy

     Etec confirming that certain closing conditions have been satisfied; and
     (5) the written resignations of all officers and directors of Etec and
     its subsidiaries effective as of completion of the merger;

  .  Stephen E. Cooper, and not more than one of three other specified
     executive officers of Etec, shall not, other than by reason of their
     death or disability, have ceased to be employed by Etec or provided oral
     or written notice to Etec or Applied Materials indicating their
     intention to terminate employment with Etec or to decline employment
     with Applied Materials;

  .  there shall not have occurred any material adverse effect on Etec and
     its subsidiaries since the date of the merger agreement, and no event
     shall have occurred or circumstance shall exist that, alone or in
     combination with any other events or circumstances, could reasonably be
     expected to have a material adverse effect on Etec and its subsidiaries;

  .  there shall not be pending or threatened any action or legal proceeding
     involving any governmental entity that challenges or seeks to prohibit

     commenced by a stockholder of Etec against Etec or its directors,
     officers or professional advisors as a result of the announcement of the
     merger).

   As used in the merger agreement, "material adverse effect" means, with
respect to Etec and its subsidiaries, any event, inaccuracy or other matter
that, when considered together with certain other events, inaccuracies or other
matters, had or could reasonably be expected to have a material adverse effect
on (i) the business, financial condition, capitalization, assets, liabilities,
operations or financial performance of Etec and its subsidiaries taken as a
whole, (ii) the ability of Etec to consummate the merger or any of the other
transactions contemplated by the merger agreement or to perform any of its
obligations under the merger agreement, or (iii) Applied Materials' ability to
vote, receive dividends with respect to or otherwise exercise ownership rights
with respect to the stock of Etec. However, none of the following, in and of
themselves, will be deemed to have a material adverse effect on Etec and its
subsidiaries:

  .  an event, inaccuracy or other matter that results from conditions
     affecting the U.S. economy in general;

  .  an event, inaccuracy or other matter that results from conditions
     affecting the semiconductor industry or the semiconductor equipment
     industry generally, so long as such conditions do not affect Etec and
     its subsidiaries in a materially disproportionate manner;

                                       55
<PAGE>

  .  an event, inaccuracy, or other matter that results from the taking of
     any action expressly required by the merger agreement; and

  .  a decline in Etec's stock price.

   Conditions to the Obligation of Etec. The obligation of Etec to complete the
merger is subject to the satisfaction of the following additional conditions:

  .  the representations and warranties made by Applied Materials in the
     merger agreement shall be accurate in all respects as of the date of the
     merger agreement and also as of the closing date as if made on the
     closing date, except that any inaccuracies in Applied Materials'
     representations and warranties will be disregarded if the circumstances
     giving rise to all inaccuracies considered collectively do not
     constitute, and would not reasonably be expected to have, a material
     adverse effect on Applied Materials;

  .  Applied Materials shall have complied in all material respects with all
     of its covenants and obligations in the merger agreement required to be
     complied with at or prior to the completion of the merger; and

  .  Etec shall have received: (1) a tax opinion that the merger will
     constitute a reorganization for federal income tax purposes; and (2) a
     certificate executed by the Chief Executive Officer of Applied Materials
     on behalf of Applied Materials confirming that certain closing
     conditions have been satisfied.

   As used in the merger agreement, "material adverse effect" means, with
respect to Applied Materials, any event, inaccuracy or other matter that, when
considered together with certain other events, inaccuracies or other matters,
had or would reasonably be expected to have a material adverse effect on the
business, financial condition, capitalization, assets, liabilities, operations
or financial performance of Applied Materials and its subsidiaries taken as a
whole, or the ability of Applied Materials to consummate the merger or any of
the other transactions contemplated by the merger agreement or to perform any
of its obligations under the merger agreement. However, none of the following,
in and of themselves, will be deemed to have a material adverse effect on
Applied Materials:

  .  an event, inaccuracy or other matter that results from conditions
     affecting the U.S. economy in general;

  .  an event, inaccuracy or other matter that results from conditions
     affecting the semiconductor industry or the semiconductor equipment
     industry generally, so long as such conditions do not affect Applied
     Materials in a materially disproportionate manner;

  .  an event, inaccuracy or other matter that results from the taking of any
     action expressly required by the merger agreement; and

  .  a decline in Applied Materials' stock price.

Termination of the Merger Agreement

   Applied Materials and Etec can agree by mutual written consent to terminate
the merger agreement at any time before the merger is completed. In addition,
either company can terminate the merger agreement if:

  .  the merger is not completed on or before August 31, 2000, unless the
     failure to consummate the merger is attributable to a failure on the
     part of the party seeking to terminate the merger agreement to perform
     any material obligation;

  .  a court or government entity issues a final order prohibiting the
     merger;

  .  the Etec stockholders do not approve the merger agreement; or

  .  the other company materially breaches its representations, warranties or
     covenants in the merger agreement and the breach is not curable through
     the exercise of reasonable efforts or the other company is not using
     reasonable efforts to cure the breach.

                                       56
<PAGE>

   In addition, Applied Materials can terminate the merger agreement, before
the receipt of the Etec stockholder approval, if any of the following (a
"Triggering Event") occurs:

  .  the Etec board of directors fails to recommend that the Etec
     stockholders vote to approve the merger agreement, withdraws or
     adversely modifies its recommendation that the Etec stockholders vote to
     approve the merger agreement or approves, endorses or recommends another
     Acquisition Proposal (as defined above);

  .  Etec enters into a letter of intent or similar document or agreement
     relating to another Acquisition Proposal;

  .  a tender or exchange offer relating to securities of Etec is commenced,
     and Etec does not send to its securityholders, within 10 business days
     after the commencement of the tender or exchange offer, a statement
     disclosing that Etec recommends rejection of the tender or exchange
     offer;

  .  another Acquisition Proposal is publicly announced and Etec fails to
     issue a press release announcing its opposition to the Acquisition
     Proposal within 10 business days after the Acquisition Proposal is
     announced;

  .  any person or group of persons acquires or agrees to acquire, or
     discloses an intention to acquire, Etec securities representing more
     than 15% of the outstanding securities of any class of voting securities
     of Etec;

  .  Etec materially breaches its agreement not to solicit or encourage, or
     participate in discussions or negotiations with respect to, Acquisition
     Proposals from or with parties other than Applied Materials; or

  .  Etec fails to hold the special meeting of its stockholders within 60
     days after the effective date of the registration statement of which
     this proxy statement/prospectus is a part.

   Etec would be required to pay Applied Materials a termination fee if the
merger agreement is terminated by Applied Materials under any of these
circumstances. Subject to limited exceptions, including the survival of Etec's
agreement to pay a termination fee to Applied Materials under certain
circumstances, if the merger agreement is terminated, then it will be of no
further effect, there will be no liability on the part of Applied Materials or
Etec to the other, and all rights and obligations of the parties will cease.
However, no party will be relieved from its obligations with respect to any
breach of any representation, warranty or covenant contained in the merger
agreement.

Expenses and Termination Fee

   The merger agreement provides that, regardless of whether Applied Materials
and Etec consummate the merger, each of Etec and Applied Materials will pay its
own costs and expenses incurred in connection with the merger agreement and the
transactions contemplated by the merger agreement, except that Applied
Materials and Etec have agreed to share equally all fees and expenses, other
than attorneys' fees, incurred in connection with (i) the filing, printing and
mailing of this proxy statement/prospectus and any amendments or supplements
and (ii) the filing by the parties of the premerger notification and report
forms relating to the merger under the HSR Act and the filing of any notice or
other document under any applicable foreign antitrust law or regulation.

   Etec has agreed to pay Applied Materials a termination fee in the amount of
$54 million within seven business days after Applied Materials terminates the
merger agreement, if Applied Materials terminates the merger agreement because:

  .  the Etec board of directors fails to recommend that Etec's stockholders
     vote to approve the merger agreement, withdraws or adversely modifies
     its recommendation that Etec stockholders vote to approve the merger
     agreement or approves, endorses or recommends another Acquisition
     Proposal (as defined above);

                                       57
<PAGE>

  .  Etec enters into a letter of intent or similar document or agreement
     relating to another Acquisition Proposal;

  .  a tender or exchange offer relating to securities of Etec is commenced,
     and Etec does not send to its securityholders, within 10 business days
     after the commencement of the tender or exchange offer, a statement
     disclosing that Etec recommends rejection of the tender or exchange
     offer;

  .  another Acquisition Proposal is publicly announced and Etec fails to
     issue a press release announcing its opposition to the Acquisition
     Proposal within 10 business days after the Acquisition Proposal is
     announced;

  .  any person or group of persons acquires or agrees to acquire, or
     discloses an intention to acquire, Etec securities representing more
     than 15% of the outstanding securities of any class of voting securities
     of Etec;

  .  Etec materially breaches its agreement not to solicit or encourage, or
     participate in discussions or negotiations with respect to, Acquisition
     Proposals from or with parties other than Applied Materials; or

  .  Etec fails to hold the special meeting of its stockholders within 60
     days after the effective date of the registration statement of which
     this proxy statement/prospectus is a part.

   In addition, Etec has agreed to pay Applied Materials a termination fee in
the amount of $54 million if:

  .  the merger agreement is terminated by Applied Materials or Etec because
     the Etec stockholders fail to approve the merger agreement;

  .  at or prior to such termination, an Acquisition Proposal was disclosed,
     commenced, submitted or made; and

  .  within 270 days after termination of the merger agreement, Etec
     consummates an Acquisition Transaction or Etec or any of its
     subsidiaries has entered into a contract contemplating an Acquisition
     Transaction.

   For this purpose, "Acquisition Proposal" and "Acquisition Transaction" have
the same meanings referred to above on page 53, except that all references to
"15%" in the definition of "Acquisition Transaction" refer instead to "35%".

                             STOCK OPTION AGREEMENT

   The following description of the stock option agreement describes the
material terms of the stock option agreement between Applied Materials and
Etec, dated as of January 12, 2000. The full text of the stock option agreement
is attached as Annex C to this proxy statement/prospectus and is incorporated
in this proxy statement/prospectus by reference. We encourage you to read the
entire stock option agreement.

   In order to induce Applied Materials to enter into the merger agreement,
Etec granted to Applied Materials an irrevocable option to purchase newly
issued shares of Etec common stock representing up to 19.9% of Etec common
stock outstanding. The purchase price per option share is $82.46.

Purpose of the Option

   The option is intended to increase the likelihood that the merger will be
completed on its agreed terms. The option could prevent an alternative
acquisition transaction with Etec from being accounted for as a "pooling of
interests" for financial accounting purposes. The option therefore may have the
effect of discouraging others from making acquisition proposals to Etec before
the completion of the merger with Applied Materials, even if they might be
prepared to offer to provide consideration to Etec stockholders that has a
higher current market price then the shares of Applied Materials common stock
to be received by Etec stockholders in the merger.

Exercisability of the Option

   The option may be exercised: (a) immediately prior to Etec being required to
pay a termination fee to Applied Materials in circumstances in which a
termination fee is due because the Etec stockholders failed to approve the
merger agreement, an Acquisition Proposal was disclosed, commenced, submitted
or made and within 270 days after termination of the merger agreement, Etec
consummates an Acquisition Transaction or Etec or any of its subsidiaries has
entered into a contract contemplating an Acquisition Transaction (see "Certain
Terms of the Merger Agreement--Expenses and Termination Fee"); (b) if Applied
Materials has terminated the merger agreement because of a "Triggering Event"
(see "Certain Terms of the Merger Agreement--Termination of the Merger
Agreement"); or (c) if, after the occurrence of a Triggering Event, Applied
Materials delivers to Etec a written notice containing Applied Materials'
irrevocable determination to terminate the merger agreement if the Etec
stockholders do not approve the merger agreement by the required vote upon the
failure to obtain such vote. The option will remain in effect until the
earliest to occur of: (a) the effective time, (b) the date of termination of
the merger agreement before the option becomes exercisable, or (c) the 180th
day after the date on which Applied Materials receives notice from Etec that
the option has become exercisable. Applied Materials may exercise the option,
in whole or in part, at any time during the option term following the date on
which the option becomes exercisable.

Repurchase of the Option by Etec

   For a specific period of time following the date on which the option has
become exercisable, Applied Materials has the right to require Etec to
repurchase from Applied Materials any unexercised portion of the option and all
shares of Etec common stock previously purchased by Applied Materials pursuant
to the option that Applied Materials then owns at an aggregate purchase price
specified in the stock option agreement.

Profit Limitation

   The stock option agreement limits the cash payment that Applied Materials
may receive after exercise of the option and sale of shares of Etec common
stock or upon the repurchase of the option by Etec. If Applied Materials
exercises the option and sells any option shares or if Applied Materials causes
Etec to repurchase the option, in no event shall Applied Materials' total
profit exceed $54 million (when combined with any termination fee paid to
Applied Materials by Etec). If Applied Materials' total profit from the sale of
the option

                                       59
<PAGE>

shares or from the repurchase of the option by Etec (when combined with any
termination fee paid to Applied Materials by Etec) exceeds $54 million, Applied
Materials can (a) reduce the number of option shares subject to the option
agreement; (b) deliver to Etec for cancellation some option shares previously
purchased by Applied Materials; (c) pay Etec cash; or (d) do any combination of
the foregoing.

Other

   The stock option agreement contains provisions governing the procedure for
exercise of the option and payment for the shares purchased upon exercise and
other provisions that adjust the number of shares and the exercise price upon
the occurrence of certain events, such as stock dividends, divisions,
combinations, recapitalizations, exchanges of shares and other similar
transactions.

   Finally, the stock option agreement contains provisions obligating Etec to
register under the Securities Act the offering, sale and delivery by Applied
Materials of shares of Etec common stock acquired by Applied Materials upon the
exercise of the option.

                        MANAGEMENT AND OTHER INFORMATION

   After the merger, Etec will be a wholly-owned subsidiary of Applied
Materials, and all of Etec's subsidiaries will be indirect wholly-owned
subsidiaries of Applied Materials. Information relating to the management,

Beneficial Ownership of Etec Shares

   The following table and the related notes present information on the
beneficial ownership of shares of Etec common stock, as of January 12, 2000
(except as noted in the footnotes), by each director and executive officer of
Etec and by each person (other than Applied Materials) or group who is known to
the management of Etec to be the beneficial owner of more than 5% of the Etec
common stock outstanding as of January 12, 2000. This table is based upon
information supplied by executive officers, directors and principal
stockholders and Schedules 13D and 13G filed with the SEC. Where information
regarding stockholders is based on Schedules 13D and 13G, the number of shares
owned is as of the date for which information was provided in those schedules,
as noted. Unless otherwise indicated in the footnotes to this table and subject
to applicable community property laws and the voting agreements entered into
between Applied Materials and the executive officers and directors of Etec,
Etec believes that each of the stockholders named in this table has sole voting

owned. Applicable percentages are based on 21,756,938 shares of Etec common
stock outstanding on January 12, 2000, adjusted as required by rules
promulgated by the SEC. Shares of Etec common stock subject to options that are
currently exercisable or are exercisable within 60 days of January 12, 2000 are
treated as outstanding and beneficially owned by the person holding them for
the purpose of computing the percentage ownership of that person but are not
treated as outstanding for the purpose of computing the percentage ownership of
any other stockholder.

   COMPARATIVE RIGHTS OF APPLIED MATERIALS STOCKHOLDERS AND ETEC STOCKHOLDERS

   Etec is incorporated under the laws of the State of Nevada. The rights of
Etec stockholders are currently governed by the Nevada Revised Statutes and the
articles of incorporation and bylaws of Etec. Applied Materials is incorporated
under the laws of the State of Delaware. The rights of Applied Materials
stockholders are currently governed by the Delaware General Corporation Law and
the certificate of incorporation and bylaws of Applied Materials. After the
merger, Etec's stockholders will become stockholders of Applied Materials and
Etec's stockholders' rights will cease to be defined and governed by the Nevada
Revised Statutes and the articles of incorporation and bylaws of Etec, and
instead will be defined and governed by the Delaware General Corporation Law
and the certificate of incorporation and bylaws of Applied Materials.

   While the rights and privileges of stockholders of a Delaware corporation
(such as Applied Materials) are, in many instances, comparable to those of
stockholders of a Nevada corporation (such as Etec), there are differences. The
following is a summary of certain material differences between the rights of
holders of Etec common stock and the rights of holders of Applied Materials
common stock at the date of this proxy statement/prospectus. This summary is
not intended to be complete and is qualified in its entirety by reference to
the relevant provisions of the articles of incorporation and bylaws of Etec,
the certificate of incorporation and bylaws of Applied Materials, and Nevada
and Delaware law. Etec's articles of incorporation and bylaws and Applied
Materials certificate of incorporation and bylaws are filed as exhibits to SEC
filings that are incorporated by reference in the registration statement of
which this proxy statement/prospectus is a part.

   The laws of Nevada and Delaware provide that some of the statutory
provisions as they affect various rights of holders of shares may be modified
by provisions in the articles or certificate of incorporation or bylaws of the
relevant corporation. The following summary of provisions contained in Nevada
law is subject to modification by provisions contained in the articles of
incorporation and bylaws of Etec and the following summary of provisions
contained in Delaware law is subject to modification by provisions contained in
the certificate of incorporation and bylaws of Applied Materials.

Adopting, Amending or Repealing Bylaws

   Subject to the bylaws, if any, adopted by the stockholders, Nevada law
permits the directors to make the bylaws of the corporation. Even if the bylaws
confer this power on the board of directors, the stockholders also have the
power to adopt, amend or repeal bylaws. Etec's bylaws state that new bylaws may
be adopted, and the current bylaws may be amended or repealed, by a vote of the
stockholders entitled to exercise a majority of the voting power of the
corporation. Subject to the Etec stockholders' right to amend the bylaws, the
board of directors of Etec may also amend the bylaws, except for provisions of
the bylaws dealing with such matters as: (a) the indemnification of officers
and directors; (b) the authorized number of directors of the corporation;
(c) restrictions on transactions involving interested directors; and (d)
committees of the board.

   Delaware law provides that stockholders entitled to vote and the board of
directors of a Delaware corporation shall have the power to adopt new bylaws or
amend or repeal the corporation's current bylaws. Applied Materials' bylaws
permit stockholders upon the affirmative vote of holders of not less than a
majority of the total voting power of all issued and outstanding shares of
stock of the corporation entitled to vote, to adopt new bylaws or amend or
repeal the current bylaws. The board of directors of Applied Materials also has
the right to adopt new bylaws or amend or repeal any and all provisions of the
corporation's bylaws, including provisions dealing with such matters as: (a)
the indemnification of officers and directors; (b) the authorized number of
directors of the corporation; (c) restrictions on transactions involving
interested directors; and (d) committees of the board.

Size of the Board of Directors

   Under Nevada law, a corporation must have at least one director, and a
corporation may provide in its articles of incorporation or in its bylaws for a
fixed number of directors or a variable number of directors

                                       64
<PAGE>

within a fixed minimum and maximum and for the manner in which the number of
directors may be increased or decreased. If the articles or bylaws so provide,
Nevada law permits a corporation's board of directors to change the initial
number or range of directors by amendment of the corporation's bylaws or by
resolution. Etec's articles of incorporation provide that the number of
directors of Etec may be increased or decreased in the manner set forth in
Etec's bylaws provided that the number of directors shall never be less than
one. Etec's bylaws state that the initial number of directors shall be nine and
that the number of directors may be increased or decreased by a resolution of
the board of directors duly adopted by 75% of all directors. Etec currently has
eight directors.

   Under Delaware law, a corporation must have at least one director, and a
corporation may provide in its certificate of incorporation or in its bylaws
for a fixed number of directors. Under Delaware law, a corporation's board of
directors alone may change the authorized number or range of directors by
amendment of the corporation's bylaws, unless otherwise prohibited by the
corporation's certificate of incorporation (in which case a change in the
number of directors may be made only upon approval by the stockholders). The
Applied Materials bylaws state that the board of directors shall consist of 10
persons. The number of directors of the Applied Materials board may be changed
by amendment to Applied Materials' bylaws, which may be adopted by a majority
of the Applied Materials directors.

Election of Directors

   Nevada law permits directors to be divided into separate classes with
staggered terms of office. However, at least one-fourth in number must be
elected annually. Etec's bylaws state the board of directors may, by
resolution, establish a staggered board of directors, which resolution will set
forth the initial terms and the standard terms of office for each class of
directors. Etec's bylaws require that at least one-fourth of the directors be
elected at each annual meeting of stockholders, but if any such annual meeting
is not held, or the directors are not elected at such meeting, the directors
may be elected at any special meeting of stockholders. The board of directors
of Etec is currently not classified and the terms of directors are not
staggered. All directors hold office until their respective successors are
elected or until their resignation, death or removal.

   Delaware law permits directors to be divided into up to three separate
classes with staggered terms of office if the certificate of incorporation
provides for a staggered board. Applied Materials certificate of incorporation
does not provide for a staggered board. Pursuant to Applied Materials' bylaws,
directors of Applied Materials will be elected at each annual meeting of
stockholders, and will hold office until his/her successor is elected and
qualified or until his/her earlier resignation, death or removal.

Removal of Directors

   Under Nevada law, any director may be removed by the vote of the holders of
not less than two-thirds of the voting stock, subject to specific provisions
concerning the vote needed to remove individual directors of a Nevada
corporation having cumulative voting, or classes or series of shares entitled
to elect one or more directors. Etec's bylaws state that any or all of the
directors may be removed without cause if such removal is approved by not less
than two-thirds of the issued and outstanding shares entitled to vote;
provided, however, that (i) if the articles of incorporation or an amendment to
the articles provide for the election of directors by cumulative voting, no
director shall be removed from office except upon the vote or written consent
of stockholders owning sufficient shares to have prevented his or her election
to office in the first place; (ii) the articles of incorporation may require
the concurrence of a larger percentage of the stock entitled to voting power in
order to remove a director; and (iii) when by the provisions of the articles of
incorporation the holders of the shares of any class or series, voting as a
class or series, are entitled to elect one or more directors, any director so
elected may be removed only by the applicable vote of the holders of the shares
of that class or series. Currently, none of these exceptions apply.

   Under Delaware law, stockholders holding a majority of the outstanding
shares entitled to vote for directors may remove a director with or without
cause, except in cases involving classified boards or where

                                       65
<PAGE>

cumulative voting is permitted. The Applied Materials bylaws provide for
removal with or without cause by the holders of a majority of the shares
entitled to vote at an election of directors.

Filling New Seats or Vacancies on the Board of Directors

   Under Nevada law, all vacancies, including those caused by an increase in
the number of directors, may be filled by a majority of the remaining
directors, even though less than a quorum. The articles of incorporation of
Etec provide that all vacancies, including vacancies caused by an increase in
the number of directors or removal of a director, that are not filled by the
stockholders, may be filled by the remaining directors, though less than a
quorum. Etec's bylaws provide that the Etec board may fill all vacancies
created by reason of death, resignation or removal, or if the authorized number
of directors is increased or otherwise, by a majority vote of the remaining
directors, although less than a quorum, or by a sole remaining director.
Furthermore, the stockholders of Etec may elect a director or directors at any
time to fill any vacancy or vacancies not filled by the directors.

   Under Delaware law, vacancies and newly created directorships may be filled
by a majority of the directors then in office (even though less than a quorum),
unless (i) otherwise provided in the corporation's certificate of incorporation
or bylaws, or (ii) the certificate of incorporation directs that a particular
class is to elect the director, in which case any other directors elected by
that class, or a sole remaining director, must fill the vacancy. The Applied
Materials bylaws provide that when one or more directors resign and the
resignation is effective at a future date, a majority of the directors then in
office, including those who have resigned, shall have the power to fill such
vacancy or vacancies. Vacancies and newly created directorships resulting from
an increase in the authorized number of directors elected by all of the
stockholders having the right to vote as a single class may be filled by a
majority of the directors then in office, although less than a quorum, or by a
sole remaining director. If at any time, by reason of death or resignation or
other cause, Applied Materials should have no directors, then any officer or
any stockholder or an executor, administrator, trustee or guardian of a
stockholder, or other fiduciary entrusted with like responsibility for the
person or estate of a stockholder, may call a special meeting of stockholders
or apply to the Court of Chancery for a decree summarily ordering an election
as provided pursuant to Delaware law. The stockholders may elect a director at
any time to fill any vacancy not filled by the directors.

Limitation of Personal Liability

   Under Nevada law, a corporation may include in its articles of incorporation
a provision that would, subject to the limitations described below, limit or
eliminate the personal liability of directors and officers to the corporation
and its stockholders for damages for breaches of their fiduciary duty. Under
Nevada law, a provision in the articles of incorporation may not, however,
eliminate or limit the liability of a director or officer for acts or omissions
that involve intentional misconduct, fraud or a knowing violation of law or the
payment of distributions in violation of Section 78.300 of the Nevada Revised
Statutes. The Etec articles of incorporation state that no director or, to the
extent specified by the board of directors, officer will be liable to Etec or
its stockholders for damages for breach of fiduciary duty as a director or
officer, except for (a) acts or omissions which involve intentional misconduct,
fraud or a knowing violation of law, or (b) the unlawful payment of dividends.

   Under Delaware law, a corporation may include in its certificate of
incorporation a provision that would, subject to the limitations described
below, limit or eliminate directors' liability for monetary damages for
breaches of their fiduciary duty of care. Under Delaware law, a director's
liability cannot be limited or eliminated:

  . for breaches of the duty of loyalty,

  . for acts or omissions not in good faith or that involve intentional
    misconduct or a knowing violation of law,

                                       66
<PAGE>

  . for the payment of unlawful dividends or expenditure of funds for
    unlawful stock purchases or redemptions, or

  . for transactions from which such director derived an improper personal
    benefit.

   In addition, the limitation of liability provisions may not limit a
director's liability for violation of, or otherwise relieve Applied Materials
or its directors from the necessity of complying with, federal or state
securities laws, or affect the availability of nonmonetary remedies such as
injunctive relief or rescission. The Applied Materials certificate of
incorporation states that a director will not be personally liable to Applied
Materials or its stockholders for monetary damages for breach of fiduciary duty
as a director, subject to the exceptions referred to above.

Indemnification

   Nevada law provides that a corporation may indemnify any person against
expenses, including attorneys' fees, judgments, fines and amounts paid in
settlement, other than in an action by or in the right of the corporation, by
reason of the fact that he or she is or was a director, officer, employee or
agent of the corporation, or is or was serving at the request of the
corporation in any such capacity for another enterprise; provided that he or
she acted in good faith and in a manner that he or she reasonably believed to
be in or not opposed to the best interests of the corporation, and, with
respect to a criminal action or proceeding, had no reasonable cause to believe
that his or her conduct was unlawful. For actions or suits by or in the right
of the corporation, Nevada law provides that a person may be indemnified if he
or she acted in good faith and in a manner that he or she reasonably believed
to be in or not opposed to the best interests of the corporation, except that
in such an action or suit by or in the right of the corporation, the
corporation may not indemnify a person for any claim, issue or matter as to
which the person has been adjudged by a court, after exhaustion of all appeals,
to be liable to the corporation or for amounts paid in settlement to the
corporation, unless and only to the extent that the court determines that in
view of all of the circumstances of the case, the person is fairly and
reasonably entitled to indemnification. To the extent a director, officer,
employee or agent of the corporation has been successful on the merits or
otherwise in defense of the matter or any claim, issue or matter therein, the
corporation must indemnify him or her against all expenses, including
attorneys' fees actually and reasonably incurred in the defense. Nevada law
provides that the determination of whether indemnification is proper must be
made by the stockholders; the board of directors by a vote of a quorum
consisting of directors who were not parties to the action, suit or proceeding;
by independent legal counsel if a majority of a quorum of directors who were
not parties so orders or if a quorum of directors who were not parties cannot
be obtained.

   Etec's articles of incorporation and bylaws require the corporation to
provide indemnification to the fullest extent permitted by law. The articles of
incorporation and bylaws provide that such right shall not be exclusive of any
other rights of indemnification.

   Delaware law contains indemnification provisions that are similar to the
indemnification provisions contained in Nevada law, except that, in certain
instances, Delaware law is possibly less favorable to the indemnitee than
Nevada law. Applied Materials' certificate of incorporation provides that
Applied Materials will indemnify its directors, officers, employees and agents
to the fullest extent permitted by Delaware law.

Transactions Involving Directors and Officers

   Under Nevada law, there is no specific provision concerning or prohibition
against loans or guarantees made by a corporation for the benefit of a director
or officer of the corporation.

   A contract or transaction between a Nevada corporation and one or more of
its directors or officers, or between a Nevada corporation and any other
corporation, partnership, association, or other organization in which one or
more of its directors or officers are directors or officers, or have a
financial interest, is not void or

                                       67
<PAGE>

voidable solely for that reason, or solely because the common or interested
director or officer was present, participates or votes at the board or board
committee meeting or joins in the execution of the written consent that
authorizes the contract or transaction, if any one of the following
circumstances exists:

  . the fact of the common directorship, office or financial interest is
    known to the board or committee, and the board or committee authorizes,
    approves or ratifies the contract or transaction in good faith by a vote
    sufficient for the purpose without counting the vote of the common or
    interested director;

  . the fact of the common directorship, office or financial interest is
    known to the stockholders, and they approve or ratify the contract or
    transaction in good faith by a majority vote of stockholders holding a
    majority of the voting power;

  . the fact of the common directorship, office or financial interest is not
    known to the director as of the time the transaction is brought before
    the board of directors for action; or

  . the contract or transaction is fair as to the corporation at the time
    that it is authorized or approved.

   Etec's bylaws state that Etec shall not enter into any contract or other
transaction with any corporation, firm or association of which one of the
directors is an employee, officer or agent, which contract or transaction could
involve payments by Etec to such corporation, firm or association aggregating
$100,000 or more (other than interest or dividend payments), unless such
contract or transaction has been approved by a majority of the disinterested
directors.

   A Delaware corporation may lend money to, or guarantee any obligation
incurred by, its officers or directors if, in the judgment of the board of
directors, the loan or guarantee may reasonably be expected to benefit the
corporation. Also, under Delaware law, any other contract or transaction
between the corporation and one or more of its directors or officers, or
between a Delaware corporation and any other corporation, partnership,
association, or other organization in which one or more of its directors or
officers are directors or officers, or have a financial interest, is not void
or voidable solely for that reason, or solely because the interested director
or officer was present at or participates in the board or board committee
meeting that authorizes the contract or transaction, or solely because any such
director's or officer's votes are counted for such purpose, if:

  . the material facts as to the director's or officer's relationship or
    interest and as to the contract or transaction are disclosed or known to
    the board of directors or committee, and the board or committee in good
    faith authorizes the contract or transaction by the affirmative votes of
    a majority of the disinterested directors, even though the disinterested
    directors is less than a quorum; or

  . the material facts as to the director's or officer's relationship or
    interest and as to the contract or transaction are disclosed or known to
    the stockholders entitled to vote thereon, and the contract or
    transaction is specifically approved in good faith by vote of the
    stockholders; or

  . the contract or transaction is fair as to the corporation as of the time
    it is authorized, approved or ratified by the board of directors, a
    committee thereof, or the stockholders.

Inspection of Stockholders' List and Other Corporate Documents

   Nevada law allows any person who has been a stockholder of record for at
least six months or who holds an aggregate of 5% or more of the corporation's
outstanding shares to inspect and copy the stockholders' list, articles and
bylaws. The corporation may deny inspection if the stockholder refuses to
furnish an affidavit that the inspection is not desired for a purpose which is
the business or object other than the business of the corporation and that he
or she has not at any time sold or offered for sale any stockholders' list of
any corporation or aided or abetted any person in procuring a list for that
purpose. A Nevada corporation must allow stockholders of record who own or
represent at least 15% of a corporation's shares the right, upon at least five
days written demand, to inspect the books of account and financial records of
the corporation, to make copies from them and to conduct an audit of those
records, except that any corporation listed and traded

                                       68
<PAGE>

on any recognized stock exchange or any corporation that furnishes to its
stockholders a detailed, annual financial statement is exempt from this
requirement. The corporation may deny inspection to any stockholder who refuses
to furnish an affidavit that the inspection or audit is not desired for any
purpose not related to his or her interest as a stockholder. Etec's bylaws
state that its stockholders have the right to inspect such corporate records at
such times and based upon the limitations of such rights as may be set forth in
the Nevada Revised Statutes from time to time.

   Both Applied Materials' bylaws and Delaware law state that any stockholder
of record, in person or by attorney or other agent, shall upon written demand
under oath, have the right during usual business hours to inspect for any
proper purpose the corporation's stock ledger, a list of its stockholders, and
its other books and records and to make copies or extracts from them. Under
Delaware law, a proper purpose shall mean a purpose reasonably related to such
person's interest as a stockholder.

Advance Notice of Stockholder Business

   Etec's bylaws provide that for business to be properly brought before the
annual meeting of stockholders by an Etec stockholder, the stockholder must
provide the Secretary of the corporation with timely notice in writing. To be
timely, each notice must be given either by personal delivery or by U.S. mail,
postage prepaid, to the Secretary of the corporation and received by the
Secretary not later than 60 days prior to the first anniversary of the date on
which notice of the prior year's annual meeting was mailed to stockholders. The
notice sent to the Secretary must set forth: (a) a brief description of the
business desired to be brought before the meeting and the reasons for
conducting such business at the meeting; (b) information concerning the
stockholder, including the stockholder's name and address; (c) a lawful
representation that the stockholder is entitled to vote at the meeting and
intends to appear in person or by proxy at the meeting to present the matter
specified in the notice; (d) any material interest of the stockholder in the
business specified in the notice; and (e) such other information with respect
to the matter as would be required to be included in a proxy statement
soliciting proxies for the presentation of the matter at the meeting.

   Applied Materials' bylaws state that no proposal by any person other than
the board of directors shall be submitted for the approval of stockholders at
any regular or special meeting of the stockholders of the corporation unless
the person advancing such proposal shall have delivered a written notice to the
Secretary of the corporation no later than the close of business 45 days prior
to the month and day of mailing the prior year's proxy statement. Such notice
shall set forth: (a) the name and address of the person advancing the proposal;
(b) any material interest of such person in the proposal; and (c) such other
information concerning the person making the proposal and the proposal itself
as would be required by the appropriate rules and regulations of the Securities
and Exchange Commission to be included in a proxy statement soliciting proxies
for the proposal.

Power to Call Special Meetings of Stockholders

   Nevada law does not specify who may call special meetings of stockholders.
Etec's bylaws provide that special meetings of stockholders may be called by
the chairman of the board, the chief executive officer, the president, a vice
president, the secretary or by a majority of the board of directors.

   Under Delaware law, special meetings of stockholders may be called by a
corporation's board of directors or by any other person or persons authorized
by the corporation's certificate of incorporation or bylaws. Applied Materials'
bylaws provide that special meetings of stockholders may be called by the board
of directors, the chairman of the board or by the president.

Distributions

   Under Nevada law, no distribution to or for the benefit of stockholders with
respect to their shares may be made if after giving effect to the distribution
either of the following two conditions are met: (a) the corporation

                                       69
<PAGE>

would not be able to pay its debts as they become due in the usual course of
business; or (b) the sum of the corporation's assets would be less than the sum
of its total liabilities plus any amount that would be needed to satisfy the
preferential rights upon dissolution of stockholders whose preferential rights
are superior to those receiving the distribution, if the corporation were to be
dissolved at the time of the distribution. Under Nevada law a distribution
includes the payment of a dividend, a distribution of indebtedness and the
repurchase or the redemption of shares.

   Delaware law generally provides that a corporation may declare and pay
dividends out of surplus or, when no surplus exists (and subject to specified
limitations), out of net profits for the fiscal year in which the dividend is
declared and/or for the preceding fiscal year. Surplus is defined as net assets
minus stated capital. Delaware law applies different tests to the payment of
dividends and the repurchase of shares.

   Nevada and Delaware law contain other differences with respect to
distributions, including differences relating to the time at which a
distribution is deemed to have been made.

Stockholder Approval of Certain Business Combinations

   In recent years, a number of states have adopted special laws designed to
make certain kinds of "unfriendly" corporate takeovers, or other transactions
involving a corporation and one or more of its significant stockholders, more
difficult. Certain of these laws that have been adopted in Nevada and Delaware
are summarized below.

   Sections 78.411 to 78.444 of the Nevada Revised Statutes restrict the
ability of a Nevada corporation having at least 200 stockholders of record to
engage in any "combination" with an "interested stockholder" for three years
after the interested stockholder's date of acquiring the shares that cause the
stockholder to become an interested stockholder, unless the combination or the
purchase of shares by the interested stockholder is approved by the board of
directors before that date. Under these statutes:

  . an "interested stockholder" means (1) the "beneficial owner," as defined
    in the Revised Nevada Statutes, of 10% or more of the voting power of the
    corporation, or (2) an affiliate or associate of the corporation who at
    any time within three years immediately before the date in question was
    the beneficial owner, directly or indirectly, of 10% or more of the
    voting power of the corporation; and

  . a "combination" is broadly defined to include a merger or consolidation
    of the corporation or any subsidiary of the corporation with the
    interested stockholder; any sale, mortgage or other disposition of assets
    to or with the interested stockholder exceeding certain amounts; the
    issuance or transfer of shares of the corporation or its subsidiaries to
    the interested stockholder exceeding a specified market value; the
    adoption of any plan or proposal for the liquidation or dissolution of
    the corporation proposed by the interested stockholder; transactions that
    would have the effect of increasing the proportionate share of
    outstanding shares of the corporation owned by the interested
    stockholder; or the receipt of any benefit, except proportionately as a
    stockholder, of any loans, advances or other financial benefits by an
    interested stockholder. A combination also generally includes any of the
    foregoing transactions with an affiliate or associate of the interested
    stockholder.

   If the combination was not previously approved, the interested stockholder
may effect the combination after the three-year period only if the combination
is either:

  . approved by the holders of stock representing a majority of the
    outstanding shares not beneficially owned by the interested stockholder
    at a meeting called for that purpose no earlier than three years after
    the date of acquiring shares; or

  . the combination meets statutory fair price criteria.

   The above provisions do not apply to any business combination involving a
corporation:

  . whose original articles of incorporation expressly elect not to be
    governed by such provisions;

                                       70
<PAGE>

  . which does not, as of the date of acquiring shares, have a class of
    voting shares registered with the SEC under Section 12 of the Exchange
    Act, unless the corporation's articles of incorporation provide
    otherwise;

  . whose articles of incorporation were amended to provide that the
    corporation is subject to the above provisions and which did not have a
    class of voting shares registered with the SEC under Section 12 of the
    Exchange Act on the effective date of that amendment, if the combination
    is with an interested stockholder whose date of acquiring shares is
    before the effective date of such amendment; or

  . that amends its articles of incorporation, as approved by a majority of
    the disinterested shares, to expressly elect not to be governed by the
    above provisions. This type of amendment, however, would not become
    effective until 18 months after its passage and would apply only to stock
    acquisitions occurring after the effective date of the amendment.

In addition, the above provisions will not apply to any combination with an
interested stockholder on January 1, 1991 or who became an interested
stockholder inadvertently and satisfies certain other conditions.

   The Etec articles of incorporation do not exempt Etec from the restrictions
imposed by Sections 78.411 to 78.444 of the Nevada Revised Statutes.

   Nevada's Control Share Acquisition Law, NRS 78.378 through 78.3793,
generally prohibits an acquirer from voting shares of a Nevada corporation's
stock after crossing certain threshold ownership percentages, unless the
acquirer obtains the approval of the corporation's stockholders. The Control
Share Acquisition Law only applies to Nevada corporations doing business
directly or through an affiliated corporation in Nevada with at least 200
stockholders of record, at least 100 of whom have addresses in Nevada. Etec
currently does/does not have at least 100 stockholders of record in Nevada
and/or does not do business in Nevada. The ownership thresholds are at least
one-fifth but less than one-third, at least one-third but less than a majority,
and a majority or more of all of the outstanding voting power.

   Once an acquirer crosses one of these thresholds, a special meeting of
stockholders may be called at the acquirer's request to consider the voting
rights of its shares. If the acquirer does not make a request, consideration of
the voting rights must be taken at the next special or annual meeting of
stockholders. If the corporation's articles or bylaws provide, the corporation
may call for redemption certain of the acquirer's shares if the stockholders do
not grant full voting rights or the acquirer fails to timely deliver
information to the corporation. Etec's articles of incorporation and bylaws do
not currently provide for redemption of an acquirer's shares in such
circumstances.

   If an acquirer's shares are accorded full voting rights and the acquirer has
acquired control shares with at least a majority of all the voting power, any
stockholder of record who has not voted for approval of voting rights is
entitled to demand payment for the fair value of his or her shares, which is
generally not less than the highest price per share paid in the transaction
subjecting the acquirer to the Control Share Acquisition Law. The Control Share
Acquisition Law does not apply if the articles of incorporation or bylaws in
effect on the tenth day following the crossing the thresholds described above
provide that the law does not apply to the corporation or to the acquisition
specifically by types of existing or future stockholders, whether or not
identified. Neither the articles of incorporation or bylaws of Etec currently
includes such a provision.

   Under Section 203 of the Delaware General Corporation Law, certain "business
combinations" with "interested stockholders" of Delaware corporations are
subject to a three-year moratorium unless specified conditions are met. Under
Section 203, certain business combinations with a majority stockholder require
the delivery of a fairness opinion.

   Section 203 prohibits a Delaware corporation from engaging in a business
combination with an interested stockholder for three years following the date
that the person becomes an interested stockholder. With certain exceptions, an
interested stockholder is a person or group who or which owns 15% or more of
the corporation's

                                       71
<PAGE>

outstanding voting stock (including any rights to acquire stock under an
option, warrant, agreement, arrangement or understanding, or upon the exercise
of conversion or exchange rights, and stock with respect to which the person
has voting rights only), or is an affiliate or associate of the corporation and
was the owner of 15% or more of the voting stock at any time within the
previous three years.

   For purposes of Section 203, the term "business combination" is defined
broadly to include mergers with or caused by the interested stockholder; sales
or other dispositions to the interested stockholder (except proportionately
with the corporation's other stockholders) of assets of the corporation or a
subsidiary equal to 10% or more of the total market value of the corporation's
consolidated assets or its outstanding stock; the issuance or transfer by the
corporation or a subsidiary of stock of the corporation or the subsidiary to
the interested stockholder (except for transfers in a conversion or exchange or
a pro rata distribution or certain other transactions, none of which increase
the interested stockholder's proportionate ownership of any class or series of
the corporation's or such subsidiary's stock); or receipt by the interested
stockholder of the benefit (except proportionately as a stockholder), directly
or indirectly, of any loans, advances, guarantees, pledges, or other financial
benefits provided by or through the corporation or a subsidiary.

   The three-year moratorium imposed on business combinations by Section 203
does not apply if (a) before the stockholder becomes an interested stockholder,
the board of directors approves either the business combination or the
transaction which resulted in the person becoming an interested stockholder;
(b) the interested stockholder owns 85% of the corporation's voting stock upon
completion of the transaction which made him or her an interested stockholder
(excluding from the 85% calculation shares owned by directors who are also
officers of the target corporation and shares held by employee stock plans
which do not permit employees to decide confidentially whether to accept a
tender or exchange offer); or (c) after the person becomes an interested
stockholder, the board approves the business combination, and it is also
approved at a stockholder meeting by 66.67% of the voting stock not owned by
the interested stockholder.

   Section 203 only applies to Delaware corporations which, like Applied
Materials, (a) have a class of voting stock that is listed on a national
securities exchange, are quoted on an interdealer quotation system such as the
Nasdaq National Market or (b) are held of record by more than 2,000
stockholders. However, a Delaware corporation may elect not to be governed by
Section 203 by a provision in its original certificate of incorporation or by
certain amendments to its certificate of incorporation or bylaws. Applied
Materials has not elected to not be governed by Section 203; therefore, Section
203 applies to Applied Materials.

   Section 203 has been challenged in lawsuits arising out of takeover
disputes, and it is not yet clear whether and to what extent its
constitutionality will be upheld by the courts. Although the United States
District Court for the District of Delaware has consistently upheld the
constitutionality of Section 203, the Delaware Supreme Court has not yet
considered the issue.

Mergers

   Nevada law requires that certain extraordinary corporate actions, such as
most mergers, share exchanges and sales of all of a corporation's assets, be
approved by the affirmative vote of a majority of the corporation's outstanding
shares. Nevada law does not require a stockholder vote of the surviving
corporation in a merger if (a) the articles of incorporation of the surviving
corporation will not differ from its articles before the merger, (b) each
stockholder of the surviving corporation whose shares were outstanding before
the merger holds an identical number of shares with identical characteristics
after the merger, and (c) the number of voting shares (shares that entitle
their holders to vote unconditionally in elections of directors) and
participating shares (shares that entitle their holders to participate without
limitation in distributions) to be issued by the surviving corporation in the
merger plus in each case the number of voting or participating shares issued or
issuable, as the case may be, as a result of the merger either by conversion of
securities issued pursuant to the merger or the exercise of rights or warrants
issued pursuant to the merger does not exceed by more than 20% such voting and
participating shares outstanding immediately before the merger. Delaware law
generally requires that a majority of the outstanding shares of each of the
acquiring and target corporations that are constituent

                                       72
<PAGE>

corporations in a statutory merger approve such merger. Delaware law does not
require a stockholder vote of the surviving corporation in a merger if (a) the
merger agreement does not amend the existing certificate of incorporation, (b)
each share of the surviving corporation outstanding before the merger is an
identical outstanding share after the merger, and (c) the number of shares to
be issued by the surviving corporation in the merger does not exceed 20% of the
shares outstanding immediately before the merger. Delaware law also requires
that a sale of all or substantially all of the assets of a corporation be
approved by a majority of the voting shares of the corporation transferring
such assets.

   The Applied Materials certificate of incorporation requires the vote of
holders of not less than 66.67% of the outstanding shares of voting stock to
approve any business combination involving Applied Materials or any subsidiary
of Applied Materials with a "related person" notwithstanding the fact that a
lesser percentage may be specified by law. However, the 66.67% voting
requirement shall not be applicable and a business combination shall require
only such affirmative vote as required by law, if among other things, a
majority of the board of directors approve the business combination either in
advance of or subsequent to such related person becoming a related person. A
"related person" is defined in Applied Materials' certificate of incorporation
as any person who or which (a) is the beneficial owner of 15% of more of the
voting stock of Applied Materials, (b) is an affiliate or associate of Applied
Materials and at any time within the two-year period immediately prior to the
date of determining whether a person is a "related person" was the beneficial
owner of 15% or more of the voting stock, or (c) is an assignee of or has
otherwise succeeded to the beneficial ownership of any shares of voting stock
which were at any time within the two-year period immediately prior to such
time beneficially owned by any related person, if such assignment or succession
shall have occurred in the course of a transaction or series of transactions
not involving a public offering within the meaning of the Securities Act of
1933.

Dissolution

   Under Nevada law, the board of directors of a corporation that has issued
stock must recommend dissolution to the stockholders and the stockholders must
approve dissolution. Under Delaware law, a dissolution must be approved by
stockholders holding 100% of the total voting power or the dissolution must be
initiated by the board of directors and approved by the holders of a majority
of the outstanding voting shares of the corporation. The procedures contained
in Nevada law relating to the dissolution and liquidation of a corporation
differ somewhat from the procedures contained in Delaware law.

   THIS SUMMARY OF CERTAIN MATERIAL DIFFERENCES IN THE CORPORATION LAWS OF
NEVADA AND DELAWARE, THE ETEC ARTICLES AND THE APPLIED MATERIALS CERTIFICATE,
AND THE ETEC BYLAWS AND THE APPLIED MATERIALS BYLAWS DOES NOT PURPORT TO BE A
COMPLETE LISTING OF DIFFERENCES IN THE RIGHTS AND REMEDIES OF HOLDERS OF SHARES
OF NEVADA, AS OPPOSED TO DELAWARE, CORPORATIONS, OR STOCKHOLDERS OF ETEC AND
APPLIED MATERIALS IN PARTICULAR. THE DIFFERENCES CAN BE DETERMINED IN FULL BY
REFERENCE TO NEVADA LAW AND DELAWARE LAW, TO THE ETEC ARTICLES OF INCORPORATION
AND THE APPLIED MATERIALS CERTIFICATE OF INCORPORATION, AND TO THE ETEC BYLAWS
AND THE APPLIED MATERIALS BYLAWS. IN ADDITION, THE LAWS OF NEVADA AND DELAWARE
PROVIDE THAT SOME OF THE STATUTORY PROVISIONS AS THEY AFFECT VARIOUS RIGHTS OF
HOLDERS OF SHARES MAY BE MODIFIED BY PROVISIONS IN THE ARTICLES OF
INCORPORATION OR BYLAWS OF THE CORPORATION.

                      AGREEMENT AND PLAN OF REORGANIZATION

   This Agreement and Plan of Reorganization ("Agreement") is made and entered
into as of January 12, 2000, by and among: Applied Materials, Inc., a Delaware
corporation ("Parent"); Boston Acquisition Sub, Inc., a Nevada corporation and
a wholly owned subsidiary of Parent ("Merger Sub"); and Etec Systems, Inc., a
Nevada corporation (the "Company"). Certain capitalized terms used in this
Agreement are defined in Exhibit A.

                                    Recitals

   A. Parent, Merger Sub and the Company intend to effect a merger of Merger
Sub into the Company in accordance with this Agreement and the applicable
provisions of Chapter 92A of the Nevada Revised Statutes (the "Merger"). Upon
consummation of the Merger, Merger Sub will cease to exist, and the Company
will become a wholly owned subsidiary of Parent.

   B. It is intended that the Merger qualify as a tax-free reorganization
within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as
amended (the "Code"). For financial reporting purposes, it is intended that the
Merger be accounted for as a "pooling of interests."

   C. The respective boards of directors of Parent, Merger Sub and the Company
have approved this Agreement and approved the Merger.

   D. In order to induce Parent to enter into this Agreement and to consummate
the Merger, concurrently with the execution of this Agreement the Company is
entering into a stock option agreement with Parent (the "Stock Option
Agreement"), pursuant to which the Company has granted to Parent an option,
exercisable under the circumstances specified therein, to purchase shares of
Company Common Stock.

                                   Agreement

   The parties to this Agreement, intending to be legally bound, agree as
follows:

Section 1. Description of Transaction

   1.1 Merger of Merger Sub into the Company. Upon the terms and subject to the
conditions set forth in this Agreement, at the Effective Time (as defined in
Section 1.3), Merger Sub shall be merged with and into the Company, and the
separate existence of Merger Sub shall cease. The Company will continue as the
surviving corporation in the Merger (the "Surviving Corporation").

   1.2 Effect of the Merger. The Merger shall have the effects set forth in
this Agreement and in the applicable provisions of Chapter 92A of the Nevada
Revised Statutes.

   1.3 Closing; Effective Time. The consummation of the transactions
contemplated by this Agreement (the "Closing") shall take place at the offices
of Cooley Godward LLP, Five Palo Alto Square, 3000 El Camino Real, Palo Alto,
California, at 10:00 a.m. on a date to be designated by Parent (the "Closing
Date"), which shall be no later than the fifth business day after the
satisfaction or waiver of the last to be satisfied or waived of the conditions
set forth in Sections 6 and 7 (other than those conditions that by their nature
are to be satisfied at the Closing, but subject to the satisfaction or waiver
of such conditions). Subject to the provisions of this Agreement, articles of
merger satisfying the applicable requirements of Chapter 92A of the Nevada
Revised Statutes shall be duly executed by the Company and Merger Sub and,
simultaneously with or as soon as practicable following the Closing, delivered
to the Nevada Secretary of State for filing. The Merger shall become effective
at the time such articles of merger are filed with the Nevada Secretary of
State or at such later time as may be specified in such articles of merger (the
"Effective Time").

                                      A-1
<PAGE>

   1.4 Articles of Incorporation and Bylaws; Directors and Officers. Unless
otherwise determined by Parent prior to the Effective Time:

     (a) the Articles of Incorporation of the Surviving Corporation shall be
  amended and restated immediately after the Effective Time to conform to
  Exhibit B;

     (b) the Bylaws of the Surviving Corporation shall be amended and
  restated as of the Effective Time to conform to the Bylaws of Merger Sub as
  in effect immediately prior to the Effective Time; and

     (c) the directors and officers of the Surviving Corporation immediately
  after the Effective Time shall be the respective individuals who are
  directors and officers of Merger Sub immediately prior to the Effective
  Time.

   1.5 Conversion of Shares.

     (a) At the Effective Time, by virtue of the Merger and without any
  further action on the part of Parent, Merger Sub, the Company or any
  stockholder of the Company:

       (i) any shares of Company Common Stock then held by the Company or
    any wholly owned Subsidiary of the Company (or held in the Company's
    treasury) (together with any associated Rights, as defined in Section
    2.3) shall be canceled and retired and shall cease to exist, and no
    consideration shall be delivered in exchange therefor;

       (ii) any shares of Company Common Stock then held by Parent, Merger
    Sub or any other wholly owned Subsidiary of Parent (together with any
    associated Rights) shall be canceled and retired and shall cease to
    exist, and no consideration shall be delivered in exchange therefor;

       (iii) except as provided in clauses "(i)" and "(ii)" above and
    subject to Sections 1.5(b), 1.5(c) and 1.5(d), each share of Company
    Common Stock then outstanding (together with any associated Rights)
    shall be converted into the right to receive 0.649 of a share of Parent
    Common Stock; and

       (iv) each share of the common stock, no par value, of Merger Sub
    then outstanding shall be converted into one share of common stock of
    the Surviving Corporation.

The fraction of a share of Parent Common Stock specified in clause "(iii)" of
the preceding sentence (as such fraction may be adjusted in accordance with
Section 1.5(b)) is referred to as the "Exchange Ratio."

     (b) If, between the date of this Agreement and the Effective Time, the
  outstanding shares of Company Common Stock or Parent Common Stock are
  changed into a different number or class of shares by reason of any stock
  split, division or subdivision of shares, stock dividend, reverse stock
  split, reclassification, recapitalization or other similar transaction,
  then the Exchange Ratio shall be appropriately adjusted.

     (c) If any shares of Company Common Stock outstanding immediately prior
  to the Effective Time are unvested or are subject to a repurchase option,
  risk of forfeiture or other condition under any applicable restricted stock
  purchase agreement or other agreement with the Company or under which the
  Company has any rights, then the shares of Parent Common Stock issued in
  exchange for such shares of Company Common Stock will also be unvested and
  subject to the same repurchase option, risk of forfeiture or other
  condition, and the certificates representing such shares of Parent Common
  Stock may accordingly be marked with appropriate legends. The Company shall
  take all action that may be necessary to ensure that, from and after the
  Effective Time, Parent is entitled to exercise any such repurchase option
  or other right set forth in any such restricted stock purchase agreement or
  other agreement.

     (d) No fractional shares of Parent Common Stock shall be issued in
  connection with the Merger, and no certificates or scrip for any such
  fractional shares shall be issued. Any holder of Company Common Stock who
  would otherwise be entitled to receive a fraction of a share of Parent
  Common Stock (after aggregating all fractional shares of Parent Common
  Stock issuable to such holder) shall, in lieu of such fraction of a share
  and upon surrender of such holder's Company Stock Certificate(s) (as
  defined in

                                      A-2
<PAGE>

  Section 1.6), be paid in cash the dollar amount (rounded to the nearest
  whole cent), without interest, determined by multiplying such fraction by
  the closing price of a share of Parent Common Stock on the Nasdaq National
  Market on the date the Merger becomes effective.

   1.6 Closing of the Company's Transfer Books. At the Effective Time: (a) all
shares of Company Common Stock outstanding immediately prior to the Effective
Time shall automatically be canceled and retired and shall cease to exist, and
all holders of certificates representing shares of Company Common Stock that
were outstanding immediately prior to the Effective Time shall cease to have
any rights as stockholders of the Company; and (b) the stock transfer books of
the Company shall be closed with respect to all shares of Company Common Stock
outstanding immediately prior to the Effective Time. No further transfer of any
such shares of Company Common Stock shall be made on such stock transfer books
after the Effective Time. If, after the Effective Time, a valid certificate
previously representing any shares of Company Common Stock (a "Company Stock
Certificate") is presented to the Exchange Agent (as defined in Section 1.7) or
to the Surviving Corporation or Parent, such Company Stock Certificate shall be
canceled and shall be exchanged as provided in Section 1.7.

   1.7 Exchange of Certificates.

     (a) On or prior to the Closing Date, Parent shall select a reputable
  bank or trust company to act as exchange agent in the Merger (the "Exchange
  Agent"). Promptly after the Effective Time, Parent shall deposit with the
  Exchange Agent (i) certificates representing the shares of Parent Common
  Stock issuable pursuant to this Section 1, and (ii) cash sufficient to make
  payments in lieu of fractional shares in accordance with Section 1.5(d).
  The shares of Parent Common Stock and cash amounts so deposited with the
  Exchange Agent, together with any dividends or distributions received by
  the Exchange Agent with respect to such shares, are referred to
  collectively as the "Exchange Fund."

     (b) As soon as reasonably practicable after the Effective Time, the
  Exchange Agent will mail to the record holders of Company Stock
  Certificates (i) a letter of transmittal in customary form and containing
  such provisions as Parent may reasonably specify (including a provision
  confirming that delivery of Company Stock Certificates shall be effected,
  and risk of loss and title to Company Stock Certificates shall pass, only
  upon delivery of such Company Stock Certificates to the Exchange Agent),
  and (ii) instructions for use in effecting the surrender of Company Stock
  Certificates in exchange for certificates representing Parent Common Stock.
  Upon surrender of a Company Stock Certificate to the Exchange Agent for
  exchange, together with a duly executed letter of transmittal and such
  other documents as may be reasonably required by the Exchange Agent or
  Parent, (1) the holder of such Company Stock Certificate shall be entitled
  to receive in exchange therefor a certificate representing the number of
  whole shares of Parent Common Stock that such holder has the right to
  receive pursuant to the provisions of Section 1.5 (and cash in lieu of any
  fractional share of Parent Common Stock), and (2) the Company Stock
  Certificate so surrendered shall be canceled. Until surrendered as
  contemplated by this Section 1.7(b), each Company Stock Certificate shall
  be deemed, from and after the Effective Time, to represent only the right
  to receive shares of Parent Common Stock (and cash in lieu of any
  fractional share of Parent Common Stock) as contemplated by this Section 1.
  If any Company Stock Certificate shall have been lost, stolen or destroyed,
  Parent may, in its discretion and as a condition precedent to the issuance
  of any certificate representing Parent Common Stock, require the owner of
  such lost, stolen or destroyed Company Stock Certificate to provide an
  appropriate affidavit and to deliver a bond (in such sum as Parent may
  reasonably direct) as indemnity against any claim that may be made against
  the Exchange Agent, Parent or the Surviving Corporation with respect to
  such Company Stock Certificate.

     (c) Notwithstanding anything to the contrary contained in this
  Agreement, no shares of Parent Common Stock (or certificates therefor)
  shall be issued in exchange for any Company Stock Certificate to any Person
  who may be an "affiliate" (as that term is used in Rule 145 under the
  Securities Act) of the Company until such Person shall have delivered to
  Parent a duly executed Affiliate Agreement as contemplated by Section 5.10.

                                      A-3
<PAGE>

     (d) No dividends or other distributions declared or made with respect to
  Parent Common Stock with a record date after the Effective Time shall be
  paid to the holder of any unsurrendered Company Stock Certificate with
  respect to the shares of Parent Common Stock that such holder has the right
  to receive in the Merger until such holder surrenders such Company Stock
  Certificate in accordance with this Section 1.7 (at which time such holder
  shall be entitled, subject to the effect of applicable escheat or similar
  laws, to receive all such dividends and distributions, without interest).

     (e) Any portion of the Exchange Fund that remains undistributed to
  holders of Company Stock Certificates as of the date 180 days after the
  date on which the Merger becomes effective shall be delivered to Parent
  upon demand, and any holders of Company Stock Certificates who have not
  theretofore surrendered their Company Stock Certificates in accordance with
  this Section 1.7 shall thereafter look only to Parent for satisfaction of
  their claims for Parent Common Stock, cash in lieu of fractional shares of
  Parent Common Stock and any dividends or distributions with respect to
  Parent Common Stock.

     (f) Each of the Exchange Agent, Parent and the Surviving Corporation
  shall be entitled to deduct and withhold from any consideration payable or
  otherwise deliverable pursuant to this Agreement to any holder or former
  holder of Company Common Stock such amounts as may be required to be
  deducted or withheld therefrom under the Code or any provision of state,
  local or foreign tax law or under any other applicable Legal Requirement.
  To the extent such amounts are so deducted or withheld, such amounts shall
  be treated for all purposes under this Agreement as having been paid to the
  Person to whom such amounts would otherwise have been paid.

     (g) Neither Parent nor the Surviving Corporation shall be liable to any
  holder or former holder of Company Common Stock or to any other Person with
  respect to any shares of Parent Common Stock (or dividends or distributions
  with respect thereto), or for any cash amounts, delivered to any public
  official pursuant to any applicable abandoned property law, escheat law or
  similar Legal Requirement.

   1.8 Tax Consequences. For federal income tax purposes, the Merger is
intended to constitute a reorganization within the meaning of Section 368 of
the Code. The parties to this Agreement hereby adopt this Agreement as a "plan
of reorganization" within the meaning of Sections 1.368-2(g) and 1.368-3(a) of
the United States Treasury Regulations.

   1.9 Accounting Consequences. For financial reporting purposes, the Merger is
intended to be accounted for as a "pooling of interests."

   1.10 Further Action. If, at any time after the Effective Time, any further
action is determined by Parent to be necessary or desirable to carry out the
purposes of this Agreement or to vest the Surviving Corporation with full
right, title and possession of and to all rights and property of Merger Sub and
the Company, the officers and directors of the Surviving Corporation and Parent
shall be fully authorized (in the name of Merger Sub, in the name of the
Company and otherwise) to take such action.

     (u) none of the Acquired Corporations has agreed or committed to take
  any of the actions referred to in clauses "(c)" through "(t)" above.

   2.6 Title to Assets. The Acquired Corporations own, and have good and valid
title to, all assets purported to be owned by them, including: (i) all assets
reflected on the Unaudited Interim Balance Sheet (except for inventory sold or
otherwise disposed of in the ordinary course of business since the date of the

business and that do not (in any case or in the aggregate) materially detract
from the value of the assets subject thereto or materially impair the
operations of any of the Acquired Corporations, and (3) liens described in Part

   2.7 Receivables; Customers; Inventories.

     (a) Except as set forth in Part 2.7 of the Company Disclosure Schedule,
  all existing accounts receivable of the Acquired Corporations (including
  those accounts receivable reflected on the Unaudited Interim Balance Sheet
  that have not yet been collected and those accounts receivable that have

<PAGE>

  and (b) are current and, to the best of the Company's knowledge, will be
  collected in full, without any counterclaim or set off (net of an allowance
  for doubtful accounts not to exceed $2,000,000 in the aggregate). Part 2.7
  of the Company Disclosure Schedule accurately identifies, and provides an
  accurate and complete breakdown of the revenues received from, each
  customer or other Person that accounted for (i) more than $1,000,000 of the
  consolidated gross revenues of the Acquired Corporations in the fiscal year
  ended July 31, 1999, or (ii) more than $1,000,000 of the consolidated gross
  revenues of the Acquired Corporations in the fiscal quarter ended October
  31, 1999. The Company has not received any notice or other communication
  (in writing or otherwise), and has not received any other information,
  indicating that any customer or other Person identified in Part 2.7 of the
  Company Disclosure Schedule may cease dealing with the Company. Between
  July 31, 1998 and the date of this Agreement, no customer or potential
  customer of any of the Acquired Corporations has canceled any order for any
  of the SPG products of any of the Acquired Corporations or indicated in a
  writing delivered to any of the Acquired Corporations that it intends to
  cancel or is considering canceling any such order (it being understood that
  the mere rescheduling of an order will not be deemed to constitute a
  cancellation of such order).

     (b) The Company has recorded all of the Acquired Corporations'
  inventories at the lower of cost or market, with cost being determined
  under the first-in, first-out method. The Company has reviewed all of the
  Acquired Corporations' inventories by product group and by product line and
  has assessed the need for excess, obsolete and slow-moving reserves, using
  reasonable and supportable assumptions and projections reflecting current
  business conditions and operating plans. The Company updates the
  computation of such reserves on an interim basis and has adjusted such
  reserves on a timely basis in accordance with U.S. generally accepted
  accounting principles applied on a consistent basis.

   2.8 Real Property; Equipment; Leaseholds. All material items of equipment
and other tangible assets owned by or leased to the Acquired Corporations are
adequate for the uses to which they are being put, are in good and safe
condition and repair (ordinary wear and tear excepted) and are adequate for the
conduct of the business of the Acquired Corporations in the manner in which
such business is currently being conducted. None of the Acquired Corporations
own any real property or any interest in real property, except for: (i) the
leaseholds created under the real property leases identified in Part 2.8(i) of
the Company Disclosure Schedule; and (ii) the land described in Part 2.8(ii) of
the Company Disclosure Schedule to which the Company has good and marketable
fee title and which is owned by the Company free and clear of any Encumbrances,
except for the Encumbrances identified in Part 2.8(ii) of the Company
Disclosure Schedule.

   2.9 Proprietary Assets.

     (a) Part 2.9(a)(i) of the Company Disclosure Schedule sets forth, with
  respect to each Proprietary Asset owned by the Acquired Corporations and
  registered with any Governmental Body or for which an application has been
  filed with any Governmental Body, (i) a brief description of such
  Proprietary Asset, and (ii) the names of the jurisdictions covered by the
  applicable registration or application. Part 2.9(a)(ii) of the Company
  Disclosure Schedule identifies and provides a brief description of all
  other Proprietary Assets owned by the Acquired Corporations that are
  material to the business of the Acquired Corporations. Part 2.9(a)(iii) of
  the Company Disclosure Schedule identifies and provides a brief description
  of, and identifies any ongoing royalty or payment obligations in excess of
  $10,000 with respect to, each Proprietary Asset that is licensed or
  otherwise made available to the Acquired Corporations by any Person and is
  material to the business of the Acquired Corporations (except for any
  Proprietary Asset that is licensed to the Acquired Corporations under any
  third party software license generally available to the public), and
  identifies the Contract under which such Proprietary Asset is being
  licensed or otherwise made available to such Acquired Corporation. The
  Acquired Corporations have good and valid title to all of the Acquired
  Corporation Proprietary Assets identified or required to be identified in
  Parts 2.9(a)(i) and 2.9(a)(ii) of the Company Disclosure Schedule, free and
  clear of all Encumbrances, except for (i) any lien for current taxes not
  yet due and payable, and (ii) minor liens that have arisen in the ordinary
  course of business and that do not (individually or in the aggregate)
  materially detract from the value of the assets subject thereto or
  materially impair the operations of any of the Acquired Corporations. The
  Acquired

                                      A-9
<PAGE>

  Corporations have a valid right to use, license and otherwise exploit all
  Proprietary Assets identified in Part 2.9(a)(iii) of the Company Disclosure
  Schedule. Except as set forth in Part 2.9(a)(iv) of the Company Disclosure
  Schedule, none of the Acquired Corporations has developed jointly with any
  other Person any Acquired Corporation Proprietary Asset that is material to
  the business of the Acquired Corporations with respect to which such other
  Person has any rights. Except as set forth in Part 2.9(a)(v) of the Company
  Disclosure Schedule, there is no Acquired Corporation Contract (with the
  exception of end user license agreements in the form previously delivered
  by the Company to Parent or non-exclusive licenses to use the Company's
  data file format for integrated circuit design data) pursuant to which any
  Person has any right (whether or not currently exercisable) to use, license
  or otherwise exploit any Acquired Corporation Proprietary Asset. Part
  2.9(a)(vi) of the Company Disclosure Schedule contains an accurate and
  complete list of each Person to whom the Company's data file formats for
  integrated circuit design data has been provided since the first shipment
  of the Company's MEBES 5000 product.

     (b) The Acquired Corporations have taken reasonable measures and
  precautions to protect and maintain the confidentiality, secrecy and value
  of all material Acquired Corporation Proprietary Assets (except Acquired
  Corporation Proprietary Assets whose value would be unimpaired by
  disclosure). Without limiting the generality of the foregoing, except as
  set forth in Part 2.9(b) of the Company Disclosure Schedule, (i) all
  current and former employees of the Acquired Corporations who are or were
  involved in, or who have contributed to, the creation or development of any
  material Acquired Corporation Proprietary Asset have executed and delivered
  to the Acquired Corporations an agreement (containing no exceptions to or
  exclusions from the scope of its coverage) that is substantially identical
  to the form of Confidential Information and Invention Assignment Agreement
  previously delivered by the Company to Parent, and (ii) all current and
  former consultants and independent contractors to the Acquired Corporations
  who are or were involved in, or who have contributed to, the creation or
  development of any material Acquired Corporation Proprietary Asset have
  executed and delivered to the Company an agreement (containing no
  exceptions to or exclusions from the scope of its coverage) that is
  substantially identical to the form of Consultant Confidential Information
  and Invention Assignment Agreement previously delivered to Parent. No
  current or former employee, officer, director, stockholder, consultant or
  independent contractor has any right, claim or interest in or with respect
  to any Acquired Corporation Proprietary Asset.

     (c) Except as set forth in Part 2.9(c) of the Company Disclosure
  Schedule, to the best of the knowledge of the Company: (i) all patents,
  trademarks, service marks and copyrights held by any of the Acquired
  Corporations are valid, enforceable and subsisting; (ii) none of the
  Acquired Corporation Proprietary Assets and no Proprietary Asset that is
  currently being developed by any of the Acquired Corporations (either by
  itself or with any other Person) infringes, misappropriates or conflicts
  with any Proprietary Asset owned or used by any other Person; (iii) none of
  the products that are or have been designed, created, developed, assembled,
  manufactured or sold by any of the Acquired Corporations is infringing,
  misappropriating or making any unlawful or unauthorized use of any
  Proprietary Asset owned or used by any other Person, and none of such
  products has at any time infringed, misappropriated or made any unlawful or
  unauthorized use of, and none of the Acquired Corporations has received any
  notice or other communication (in writing or otherwise) of any actual,
  alleged, possible or potential infringement, misappropriation or unlawful
  or unauthorized use of, any Proprietary Asset owned or used by any other
  Person; and (iv) no other Person is infringing, misappropriating or making
  any unlawful or unauthorized use of, and no Proprietary Asset owned or used
  by any other Person infringes or conflicts with, any material Acquired
  Corporation Proprietary Asset.

     (d) To the best of the knowledge of the Company, the Acquired
  Corporation Proprietary Assets constitute all the Proprietary Assets
  necessary to enable the Acquired Corporations to conduct their business in
  the manner in which such business has been and is being conducted. Except
  as set forth in Part 2.9(d) of the Company Disclosure Schedule, none of the
  Acquired Corporations has (i) licensed any of the material Acquired
  Corporation Proprietary Assets to any Person (other than Parent) on an
  exclusive basis, or (ii) entered into any covenant not to compete or
  Contract limiting its ability to exploit fully any

                                      A-10
<PAGE>

  material Acquired Corporation Proprietary Assets or to transact business in
  any market or geographical area or with any Person.

     (e) Except as set forth in Part 2.9(e)(i) of the Company Disclosure
  Schedule, since July 31, 1995 (and, to the best of the Company's knowledge,
  since inception) none of the Acquired Corporations has disclosed or
  delivered to any Person, or permitted the disclosure or delivery to any
  escrow agent or other Person of, any Acquired Corporation Source Code or
  deposited into escrow any other Acquired Corporation Proprietary Asset. No
  event has occurred, and no circumstance or condition exists, that (with or
  without notice or lapse of time) will, or could reasonably be expected to,
  result in the disclosure or delivery to any Person of any Acquired
  Corporation Source Code or the release from any escrow of any other
  Acquired Corporation Proprietary Asset. Part 2.9(e)(ii) of the Company
  Disclosure Schedule identifies each Contract pursuant to which the Company
  has deposited or is required to deposit with an escrowholder or any other
  Person any Acquired Corporation Source Code, and further describes whether
  the execution of this Agreement or the consummation of any of the
  transactions contemplated hereby could reasonably be expected to result in
  the release or disclosure of any Acquired Corporation Source Code.

     (f) To the best of the knowledge of the Company, except as set forth in
  Part 2.9(f)(i) of the Company Disclosure Schedule, each computer, computer
  program and other item of software (whether installed on a computer or on
  any other piece of equipment, including firmware) that is owned or used by
  any of the Acquired Corporations for their internal business operations is
  Year 2000 Compliant. To the best of the knowledge of the Company, except as
  set forth in Part 2.9(f)(ii) of the Company Disclosure Schedule, each
  computer program and other item of software that has been designed,
  developed, sold, licensed or otherwise made available to any Person by any
  of the Acquired Corporations is Year 2000 Compliant. To the best of the
  knowledge of the Company, except as set forth in Part 2.9(f)(iii) of the
  Company Disclosure Schedule, each of the Acquired Corporations has
  conducted sufficient Year 2000 compliance testing for each computer,
  computer program and item of software referred to in the preceding two
  sentences to be able to determine whether such computer, computer program
  and item of software is Year 2000 Compliant. For purposes of this Section
  2.9, a computer, computer program or other item of software shall be deemed
  to be "Year 2000 Compliant" only if (i) the functions, calculations and
  other computing processes of such computer, program or software perform in
  a consistent and correct manner without interruption regardless of the date
  on which such functions, calculations and processes are actually performed
  and regardless of the date input to the applicable computer system (whether
  before, on or after January 1, 2000); (ii) such computer, program or
  software accepts, calculates, compares, sorts, extracts, sequences and
  otherwise processes date inputs and date values, and returns and displays
  date values, in a consistent and correct manner regardless of the dates
  used (whether before, on or after January 1, 2000); (iii) such computer,
  program or software accepts and responds to year input in a manner that
  resolves any ambiguities as to century in a defined, predetermined and
  appropriate manner; (iv) such computer, program or software stores and
  displays date information in ways that are unambiguous as to the
  determination of the century; and (v) such computer, program or software
  determines leap years in accordance with the following standard: (A) if
  dividing the year by 4 yields an integer, it is a leap year, except for
  years ending in 00, but (B) a year ending in 00 is a leap year if dividing
  it by 400 yields an integer.

     (g) Except with respect to demonstration or trial copies, to the best of
  the knowledge of the Company, no product, system, program or software
  module designed, developed, sold, licensed or otherwise made available by
  any of the Acquired Corporations to any Person contains any "back door,"
  "time bomb," "Trojan horse," "worm," "drop dead device," "virus" or other
  software routines or hardware components designed to permit unauthorized
  access or to disable or erase software, hardware or data without the
  consent of the user.

     (a) Part 2.10 of the Company Disclosure Schedule identifies each
  Acquired Corporation Contract that constitutes a "Material Contract," other

     (b) Each Acquired Corporation Contract that constitutes a Material
  Contract is valid and in full force and effect, and is enforceable in
  accordance with its terms, subject to (i) laws of general application
  relating to bankruptcy, insolvency and the relief of debtors, and (ii)

Legal Requirements, except where the failure to comply with such Legal
Requirements has not had and would not reasonably be expected to have a
Material Adverse Effect on the Acquired Corporations. Since January 1, 1996,
none of the Acquired Corporations has received any notice or other
communication from any Governmental Body or other Person regarding any actual
or possible violation of, or failure to comply with, any Legal Requirement
(other than communications that did not give rise or relate to allegations of

  Authorizations has not had and would not reasonably be expected to have a
  Material Adverse Effect on the Acquired Corporations. All such Governmental
  Authorizations are valid and in full force and effect. Each Acquired
  Corporation is, and at all times since January 1, 1998 has been, in
  substantial compliance with the terms and requirements of such Governmental
  Authorizations, except where the failure to be in compliance with the terms
  and requirements of such Governmental Authorizations has not had and would
  not reasonably be expected to have a Material Adverse Effect on the
  Acquired Corporations. Since January 1, 1998, none of the Acquired

  Governmental Body or otherwise. Each of the Acquired Corporations is in
  full compliance with all of the terms and requirements of each grant,
  incentive and subsidy identified or required to be identified in Part
  2.15(b) of the Company Disclosure Schedule. Neither the execution, delivery
  or performance of this Agreement, nor the consummation of the Merger or any
  of the other transactions contemplated by this Agreement, will (with or
  without notice or lapse of time) give any Person the right to revoke,
  withdraw, suspend, cancel, terminate or modify any grant, incentive or
  subsidy identified or required to be identified in Part 2.15(b) of the
  Company Disclosure Schedule.

   2.16 Tax Matters.

     (b) The Unaudited Interim Balance Sheet fully accrues all actual and
  contingent liabilities for Taxes with respect to all periods through
  October 31, 1999 in accordance with generally accepted accounting
  principles. The Company will establish, in the ordinary course of business
  and consistent with its past practices, reserves adequate for the payment
  of all Taxes for the period from October 31, 1999 through the Closing Date.

  Acquired Corporation Returns has been granted (by the Company or any other
  Person), and no such extension or waiver has been requested from any
  Acquired Corporation.

     (d) No claim or Legal Proceeding is pending or, to the best of the
  knowledge of the Company, has been threatened against or with respect to
  any Acquired Corporation in respect of any material Tax. There are no
  unsatisfied liabilities for material Taxes (including liabilities for
  interest, additions to tax and penalties thereon and related expenses) with

  Acquired Corporation with respect to any material Tax (other than
  liabilities for Taxes asserted under any such notice of deficiency or
  similar document which are being contested in good faith by the Acquired
  Corporations and with respect to which adequate reserves for payment have
  been established on the Unaudited Interim Balance Sheet). There are no
  liens for material Taxes upon any of the assets of any of the Acquired
  Corporations except liens for current Taxes not yet due and payable. None

  transactions or events occurring, or accounting methods employed, prior to
  the Closing.

  condition or circumstance exists that could reasonably be expected to, give
  rise to or serve as a basis for the commencement of any such Legal
  Proceeding.

     (b) There is no material order, writ, injunction, judgment or decree to
  which any of the Acquired Corporations, or any of the assets owned or used
  by any of the Acquired Corporations, is subject. To the best of the

Company in accordance with their terms, subject to (i) laws of general
application relating to bankruptcy, insolvency and the relief of debtors, and
(ii) rules of law governing specific performance, injunctive relief and other
equitable remedies. Prior to the execution of those certain Voting Agreements
of even date herewith (the "Voting Agreements") between Parent and each of the
Persons identified in Part 2.22 of the Company Disclosure Schedule, the Board

transactions contemplated thereby. No state takeover statute or similar Legal

Corporations has taken or agreed to take, or plans to take, any action that the
Company believes could prevent Parent from accounting for the Merger as a
"pooling of interests."

Agreement or the Stock Option Agreement, will directly or indirectly (with or
without notice or lapse of time):

     (a) contravene, conflict with or result in a violation of (i) any of the
  provisions of the articles or certificate of incorporation, bylaws or other
  charter or organizational documents of any of the Acquired Corporations, or

<PAGE>

  Governmental Authorization that is held by any of the Acquired Corporations
  or that otherwise relates to the business of any of the Acquired
  Corporations or to any of the assets owned or used by any of the Acquired
  Corporations;

     (d) contravene, conflict with or result in a violation or breach of, or
  result in a default under, any provision of any Acquired Corporation
  Contract that constitutes a Material Contract, or give any Person the right
  to (i) declare a default or exercise any remedy under any such Acquired
  Corporation Contract, (ii) a rebate, chargeback, penalty or change in
  delivery schedule under any such Acquired Corporation Contract, (iii)
  accelerate the maturity or performance of any such Acquired Corporation
  Contract, or (iv) cancel, terminate or modify any term of such Acquired
  Corporation Contract;

     (e) result in the imposition or creation of any Encumbrance upon or with

Prospectus/Proxy Statement), none of the Acquired Corporations was, is or will
be required to make any filing with or give any notice to, or to obtain any
Consent from, any Person in connection with (x) the execution, delivery or
performance of this Agreement or the Stock Option Agreement by the Company, or
(y) the consummation by the Company of the Merger or any of the other
transactions contemplated by this Agreement or the Stock Option Agreement.

   2.28 Fairness Opinion. The Company's board of directors has received the
opinion of Goldman, Sachs & Co., financial advisor to the Company, dated the
date of this Agreement, to the effect that the consideration to be received by
the stockholders of the Company in the Merger is fair to the stockholders of
the Company from a financial point of view. The Company will furnish an
accurate and complete copy of said opinion to Parent.

   2.29 Financial Advisor. Except for Goldman, Sachs & Co., no broker, finder
or investment banker is entitled to any brokerage, finder's or other fee or
commission in connection with the Merger or any of the other transactions
contemplated by this Agreement based upon arrangements made by or on behalf of
any of the Acquired Corporations. The total of all fees, commissions and other
amounts that have been paid by the Company to Goldman, Sachs & Co. and all
fees, commissions and other amounts that may become payable to Goldman, Sachs &
Co. by the Company if the Merger is consummated will not exceed the amounts
specified in the letter agreement between Goldman, Sachs & Co. and the Company
that was executed on behalf of the Company on October 12, 1999. The Company has
furnished to Parent an accurate and complete copy of said letter agreement, and
there are no other agreements under which any fees, commissions or other
amounts have been paid or may become payable, or under which the Company may
have or incur any indemnification or other obligation, to Goldman, Sachs & Co.
or any of its affiliates. Except for Goldman, Sachs & Co., Wilson Sonsini
Goodrich & Rosati, P.C. and PricewaterhouseCoopers LLP, no Person is or may

   2.30 Company Rights Agreement. The Company has amended the Company Rights
Agreement to provide that neither Parent nor Merger Sub, nor any affiliate of

the Company Rights Agreement) nor a Shares Acquisition Date (as defined in the
Company Rights Agreement)

                                      A-23

shall be deemed to occur, and that the Rights will not separate from the
Company Common Stock, as a result of the execution, delivery or performance of
this Agreement, the Stock Option Agreement or the Voting Agreements or the
consummation of the Merger or any of the other transactions contemplated hereby
or thereby, and that none of the Company, Parent, Merger Sub or the Surviving
Corporation, nor any of their respective affiliates, shall have any obligations
under the Company Rights Agreement to any holder (or former holder) of Rights
as of or following the Effective Time.

Material Adverse Effect on Parent. Except as may be required by the Securities
Act, the Exchange Act, state securities or "blue sky" laws, Chapter 92A of the

  take any action that could reasonably be expected to lead to an Acquisition
  Proposal, (ii) furnish any information regarding any of the Acquired
  Corporations to any Person in connection with or in response to an
  Acquisition Proposal or an inquiry or indication of interest that could
  lead to an Acquisition Proposal, (iii) engage in discussions or
  negotiations with any Person with respect to any Acquisition Proposal, (iv)
  approve, endorse or recommend any Acquisition Proposal or (v) enter into
  any letter of intent or similar document or any Contract contemplating or
  otherwise relating to any Acquisition Transaction; provided, however, that
  prior to the approval of this Agreement by the Required Company Stockholder
  Vote, this Section 4.3(a) shall not prohibit the Company from furnishing
  nonpublic information regarding the Acquired Corporations to, or entering
  into discussions or negotiations with, any Person in response to a Superior
  Offer that is submitted to the Company by such Person (and not withdrawn)
  if (1) neither the Company nor any Representative of any of the Acquired
  Corporations shall have violated any of the restrictions set forth in this
  Section 4.3, (2) the board of directors of the Company concludes in good
  faith, after having taken into account the advice of its outside legal
  counsel, that such action is required in order for the board of directors
  of the Company to comply with its fiduciary obligations to the Company's
  stockholders under applicable law, (3) at least two business days prior to
  furnishing any such nonpublic information to, or entering into discussions
  or negotiations with, such Person, the Company gives Parent written notice
  of the identity of such Person and of the Company's intention to furnish
  nonpublic information to, or enter into discussions or negotiations with,
  such Person, and the Company receives from such Person an executed
  confidentiality agreement in substantially the same form as that certain
  Agreement Concerning Future Discussions dated September 8, 1999 between the
  Company and Parent (the "Confidentiality Agreement"), and (4) prior to
  furnishing any such nonpublic information to such Person, the Company
  furnishes such nonpublic information to Parent (to the extent such
  nonpublic information has not been previously furnished by the Company to
  Parent). The parties agree that for purposes of the preceding sentence (but
  for no other purpose), an offer that is conditioned on completion of due
  diligence shall be deemed to constitute a "Superior Offer" if such offer
  otherwise meets the definition of "Superior Offer" set forth in Exhibit A.
  Without limiting the generality of the first sentence of this Section
  4.3(a), the Company acknowledges and agrees that any violation of any of
  the restrictions set forth in the first sentence of this Section 4.3(a) by
  any Representative of any of the Acquired Corporations, whether or not such
  Representative is purporting to act on behalf of any of the Acquired
  Corporations, shall be deemed to constitute a breach of this Section 4.3 by
  the Company.

     (b) The Company shall promptly (and in no event later than one business
  day after receipt of any Acquisition Proposal, any inquiry or indication of
  interest that could reasonably be expected to lead to an Acquisition
  Proposal or any request for nonpublic information) advise Parent orally and
  in writing of any

                                      A-29
<PAGE>

  Acquisition Proposal, any inquiry or indication of interest that could
  reasonably be expected to lead to an Acquisition Proposal or any request
  for nonpublic information relating to any of the Acquired Corporations
  (including the identity of the Person making or submitting such Acquisition
  Proposal, inquiry, indication of interest or request, and the terms
  thereof) that is made or submitted by any Person during the Pre-Closing
  Period. The Company shall thereafter promptly notify Parent of any material
  change in the terms or status of any such Acquisition Proposal, inquiry,
  indication of interest or request.

     (c) The Company shall immediately cease and cause to be terminated any
  existing discussions with any Person that relate to any Acquisition
  Proposal.

     (d) The Company agrees not to release or permit the release of any
  Person from, or to waive or permit the waiver of any provision of, any
  confidentiality, "standstill" or similar agreement to which any of the
  Acquired Corporations is a party, and will use its best efforts to enforce
  or cause to be enforced each such agreement at the request of Parent. The
  Company also will promptly request each Person that has executed, within 12
  months prior to the date of this Agreement, a confidentiality agreement in
  connection with its consideration of a possible Acquisition Transaction or
  equity investment to return all confidential information heretofore
  furnished to such Person by or on behalf of any of the Acquired
  Corporations.

Section 5. Additional Covenants of the Parties

   5.1 Registration Statement; Prospectus/Proxy Statement

     (a) As promptly as practicable after the date of this Agreement, Parent
  and the Company shall prepare and cause to be filed with the SEC the
  Prospectus/Proxy Statement and Parent shall prepare and cause to be filed
  with the SEC the Form S-4 Registration Statement, in which the
  Prospectus/Proxy Statement will be included as a prospectus; provided,
  however, that notwithstanding anything to the contrary contained in this
  Section 5.1(a), if (and to the extent) Parent so elects: (i) the
  Prospectus/Proxy Statement shall initially be filed with the SEC on a
  confidential basis as a proxy statement of the Company under Section 14 of
  the Exchange Act; (ii) until such time as Parent has determined that it is
  reasonably likely that the SEC will promptly declare the Form S-4
  Registration Statement effective under the Securities Act, all amendments
  to the Prospectus/Proxy Statement shall be filed with the SEC on a
  confidential basis as amendments to the proxy statement of the Company
  under Section 14 of the Exchange Act; and (iii) Parent shall not be
  obligated to file the Form S-4 Registration Statement with the SEC until
  such time as Parent has determined that it is reasonably likely that the
  SEC will promptly declare the Form S-4 Registration Statement effective
  under the Securities Act. Each of Parent and the Company shall use all
  reasonable efforts to cause the Form S-4 Registration Statement and the
  Prospectus/Proxy Statement to comply with the rules and regulations
  promulgated by the SEC, to respond promptly to any comments of the SEC or
  its staff and to have the Form S-4 Registration Statement declared
  effective under the Securities Act as promptly as practicable after it is
  filed with the SEC. The Company will use all reasonable efforts to cause
  the Prospectus/Proxy Statement to be mailed to the Company's stockholders
  as promptly as practicable after the Form S-4 Registration Statement is
  declared effective under the Securities Act. The Company shall promptly
  furnish to Parent all information concerning the Acquired Corporations and
  the Company's stockholders that may be required or reasonably requested in
  connection with any action contemplated by this Section 5.1. If any event
  relating to any of the Acquired Corporations occurs, or if the Company
  becomes aware of any information, that should be disclosed in an amendment
  or supplement to the Form S-4 Registration Statement or the
  Prospectus/Proxy Statement, then the Company shall promptly inform Parent
  thereof and shall cooperate with Parent in filing such amendment or
  supplement with the SEC and, if appropriate, in mailing such amendment or
  supplement to the stockholders of the Company.

     (b) Prior to the Effective Time, Parent shall use reasonable efforts to
  obtain all regulatory approvals needed to ensure that the Parent Common
  Stock to be issued in the Merger will be registered or qualified under the
  securities law of every jurisdiction of the United States in which any
  registered holder of

                                      A-30
<PAGE>

  Company Common Stock has an address of record on the record date for
  determining the stockholders entitled to notice of and to vote at the
  Company Stockholders' Meeting; provided, however, that Parent shall not be
  required (i) to qualify to do business as a foreign corporation in any
  jurisdiction in which it is not now qualified or (ii) to file a general
  consent to service of process in any jurisdiction.

   5.2 Company Stockholders' Meeting.

     (a) The Company shall take all action necessary under all applicable
  Legal Requirements to call, give notice of and hold a meeting of the
  holders of Company Common Stock to vote on the approval of this Agreement
  (the "Company Stockholders' Meeting"). The Company Stockholders' Meeting
  shall be held (on a date selected by the Company in consultation with
  Parent) as promptly as practicable after the Form S-4 Registration
  Statement is declared effective under the Securities Act. The Company shall
  ensure that all proxies solicited in connection with the Company
  Stockholders' Meeting are solicited in compliance with all applicable Legal
  Requirements.

     (b) Subject to Section 5.2(c): (i) the Prospectus/Proxy Statement shall
  include a statement to the effect that the board of directors of the
  Company recommends that the Company's stockholders vote to approve this
  Agreement at the Company Stockholders' Meeting (the recommendation of the
  Company's board of directors that the Company's stockholders vote to
  approve this Agreement being referred to as the "Company Board
  Recommendation"); and (ii) the Company Board Recommendation shall not be
  withdrawn or modified in a manner adverse to Parent, and no resolution by
  the board of directors of the Company or any committee thereof to withdraw
  the Company Board Recommendation or modify the Company Board Recommendation
  in a manner adverse to Parent shall be adopted or proposed.

     (c) Notwithstanding anything to the contrary contained in Section
  5.2(b), at any time prior to the approval of this Agreement by the Required
  Company Stockholder Vote, the Company Board Recommendation may be withdrawn
  or modified in a manner adverse to Parent if: (i) an unsolicited, bona fide
  written offer to purchase all of the outstanding shares of Company Common
  Stock is made to the Company and is not withdrawn; (ii) the Company
  provides Parent with at least two business days' prior notice of any
  meeting of the Company's board of directors at which such board of
  directors will consider and determine whether such offer is a Superior
  Offer; (iii) the Company's board of directors determines in good faith
  (based upon the advice of an independent financial advisor of nationally
  recognized reputation) that such offer constitutes a Superior Offer; (iv)
  the Company's board of directors determines in good faith, based upon the
  advice of the Company's outside counsel, that, in light of such Superior
  Offer, the withdrawal or modification of the Company Board Recommendation
  is required in order for the Company's board of directors to comply with
  its fiduciary obligations to the Company's stockholders under applicable
  law; (v) the Company Board Recommendation is not withdrawn or modified in a
  manner adverse to Parent at any time within two business days after Parent
  receives written notice from the Company confirming that the Company's
  board of directors has determined that such offer is a Superior Offer; and
  (vi) neither the Company nor any of its Representatives shall have violated
  any of the restrictions set forth in Section 4.3 in any material respect.

     (d) Subject to any applicable requirements of Nevada law, the Company's
  obligation to call, give notice of and hold the Company Stockholders'
  Meeting in accordance with Section 5.2(a) shall not be limited or otherwise
  affected by the commencement, disclosure, announcement or submission of any
  Superior Offer or other Acquisition Proposal, or by any withdrawal or
  modification of the Company Board Recommendation.

   5.3 Regulatory Approvals. Each party shall use all reasonable efforts to
file, as soon as practicable after the date of this Agreement, all notices,
reports and other documents required to be filed by such party with any
Governmental Body with respect to the Merger and the other transactions
contemplated by this Agreement, and to submit promptly any additional
information requested by any such Governmental Body. Without limiting the
generality of the foregoing, the Company and Parent shall, promptly after the
date of this Agreement, prepare and file the notifications required under the
HSR Act and any applicable foreign antitrust

                                      A-31
<PAGE>

laws or regulations in connection with the Merger. The Company and Parent shall
respond as promptly as practicable to (i) any inquiries or requests received
from the Federal Trade Commission or the Department of Justice for additional
information or documentation and (ii) any inquiries or requests received from
any state attorney general, foreign antitrust authority or other Governmental
Body in connection with antitrust or related matters. Each of the Company and
Parent shall (1) give the other party prompt notice of the commencement or
threat of commencement of any Legal Proceeding by or before any Governmental
Body with respect to the Merger or any of the other transactions contemplated
by this Agreement, (2) keep the other party informed as to the status of any
such Legal Proceeding or threat, and (3) promptly inform the other party of any
communication to or from the Federal Trade Commission, the Department of
Justice or any other Governmental Body regarding the Merger. Except as may be
prohibited by any Governmental Body or by any Legal Requirement, the Company
and Parent will consult and cooperate with one another, and will consider in
good faith the views of one another, in connection with any analysis,
appearance, presentation, memorandum, brief, argument, opinion or proposal made
or submitted in connection with any Legal Proceeding under or relating to the
HSR Act or any other foreign, federal or state antitrust or fair trade law. In
addition, except as may be prohibited by any Governmental Body or by any Legal
Requirement, in connection with any Legal Proceeding under or relating to the
HSR Act or any other foreign, federal or state antitrust or fair trade law or
any other similar Legal Proceeding, each of the Company and Parent will permit
authorized Representatives of the other party to be present at each meeting or
conference relating to any such Legal Proceeding and to have access to and be
consulted in connection with any document, opinion or proposal made or
submitted to any Governmental Body in connection with any such Legal
Proceeding. At the request of Parent, the Company shall agree to divest, sell,
dispose of, hold separate or otherwise take or commit to take any action that
limits its freedom of action with respect to its or its Subsidiaries' ability
to retain any of the businesses, product lines or assets of the Company or any
of its Subsidiaries, provided that any such action is conditioned upon the
consummation of the Merger.

   5.4 Stock Options and Warrants; ESPP.

     (a) Subject to Section 5.4(b), at the Effective Time, all rights with
  respect to Company Common Stock under each Company Option (other than
  options under the ESPP) and Company Warrant then outstanding shall be
  converted into and become rights with respect to Parent Common Stock, and
  Parent shall assume each such Company Option (other than options under the
  ESPP) and Company Warrant in accordance with the terms (as in effect as of
  the date of this Agreement) of the stock option plan under which it was
  issued, if applicable, and the terms of the stock option or warrant
  agreement by which it is evidenced. From and after the Effective Time, (i)
  each Company Option and Company Warrant assumed by Parent may be exercised
  solely for shares of Parent Common Stock, (ii) the number of shares of
  Parent Common Stock subject to each such Company Option and Company Warrant
  shall be equal to the number of shares of Company Common Stock subject to
  such Company Option or Company Warrant immediately prior to the Effective
  Time multiplied by the Exchange Ratio, rounding down to the nearest whole
  share, (iii) the per share exercise price under each such Company Option
  and Company Warrant shall be adjusted by dividing the per share exercise
  price under such Company Option or Company Warrant by the Exchange Ratio
  and rounding up to the nearest cent and (iv) any restriction on the
  exercise of any such Company Option or Company Warrant shall continue in
  full force and effect and the term, exercisability, vesting schedule and
  other provisions of such Company Option or Company Warrant shall otherwise
  remain unchanged; provided, however, that each Company Option and Company
  Warrant assumed by Parent in accordance with this Section 5.4(a) shall, in
  accordance with its terms, be subject to further adjustment as appropriate
  to reflect any stock split, stock dividend, reverse stock split,
  reclassification, recapitalization or other similar transaction subsequent
  to the Effective Time. Parent shall file with the SEC, no later than ten
  business days after the date on which the Merger becomes effective, a
  registration statement on Form S-8 relating to the shares of Parent Common
  Stock issuable with respect to the Company Options assumed by Parent in
  accordance with this Section 5.4(a).

     (b) Notwithstanding anything to the contrary contained in this Section
  5.4, in lieu of assuming outstanding Company Options or Company Warrants in
  accordance with Section 5.4(a), Parent may, at its

                                      A-32
<PAGE>

  election, cause such outstanding Company Options or Company Warrants to be
  replaced by issuing replacement stock options or warrants in substitution
  therefor having the exercise price, and being exercisable for the number of
  shares, calculated in accordance with Section 5.4(a) and having other terms
  no more or less favorable to the optionee or warrantholder than the options
  or warrants that they are replacing. If Parent issues replacement stock
  options in accordance with this Section 5.4(b), then Parent shall file with
  the SEC, no later than ten business days after the date on which the Merger
  becomes effective, a registration statement on Form S-8 relating to the
  shares of Parent Common Stock issuable with respect to such replacement
  stock options.

     (c) Prior to the Effective Time, the Company shall take all action that
  may be necessary (under the plans pursuant to which Company Options are
  outstanding and otherwise) to effectuate the provisions of this Section 5.4
  and to ensure that, from and after the Effective Time, holders of Company
  Options have no rights with respect thereto other than those specifically
  provided in this Section 5.4.

     (d) As of the Effective Time, the ESPP shall be terminated. The rights
  of participants in the ESPP with respect to any offering period then
  underway under the ESPP shall be determined by treating the last business
  day prior to the Effective Time as the last day of such offering period and
  by making such other pro rata adjustments as may be necessary to reflect
  the shortened offering period but otherwise treating such shortened
  offering period as a fully effective and completed offering period for all
  purposes under the ESPP. Prior to the Effective Time, the Company shall
  take all actions (including, if appropriate, amending the terms of the
  ESPP) that are necessary to give effect to the transactions contemplated by
  this Section 5.4(d).

   5.5 Employee Benefits. Parent agrees that all employees of the Acquired
Corporations who continue employment with Parent, the Surviving Corporation or
any Subsidiary of the Surviving Corporation after the Effective Time
("Continuing Employees") shall be eligible to continue to participate in the
Surviving Corporation's health and/or welfare benefit plans; provided, however,
that (a) nothing in this Section 5.5 or elsewhere in this Agreement shall limit
the right of Parent or the Surviving Corporation to amend or terminate any such
health and/or welfare benefit plan at any time, and (b) if Parent or the
Surviving Corporation terminates any such health and/or welfare benefit plan,
then, subject to any appropriate transition period, the Continuing Employees
shall be eligible to participate in Parent's health, vacation and other non-
equity based employee benefit plans, to substantially the same extent as
similarly situated employees of Parent. The Continuing Employees shall be
given, to the extent consistent with Parent's benefit plans and with applicable
law, service credit under Parent's benefit plans, for purposes of eligibility
and vesting, equal to the service credit currently provided to such Continuing
Employees under comparable Company Employee Plans. Nothing in this Section 5.5
or elsewhere in this Agreement shall be construed to create a right in any
employee to employment with Parent, the Surviving Corporation or any Subsidiary
of the Surviving Corporation and, subject to any other binding agreement
between an employee and Parent, the Surviving Corporation or any Subsidiary of
the Surviving Corporation, the employment of each Continuing Employee shall be
"at will" employment. The Company agrees to take (or cause to be taken) all
actions necessary or appropriate to terminate, effective immediately prior to
the Effective Time, any employee benefit plan sponsored by any of the Acquired
Corporations (or in which any of the Acquired Corporations participates) that
contains a cash or deferred arrangement intended to qualify under Section
401(k) of the Code.

   5.6 Indemnification of Officers and Directors

     (a) All rights to indemnification existing in favor of those Persons who
  are directors and officers of the Company as of the date of this Agreement
  (the "Indemnified Persons") for acts and omissions occurring prior to the
  Effective Time, as provided in the Company's bylaws (as in effect as of the
  date of this Agreement) and as provided in the indemnification agreements
  between the Company and said Indemnified Persons (as in effect as of the
  date of this Agreement) in the forms disclosed by the Company to Parent
  prior to the date of this Agreement, shall survive the Merger and shall be
  observed by the Surviving Corporation to the fullest extent available under
  Nevada law. Parent agrees to guarantee and stand behind the Company's
  commitments under said indemnification agreements.

                                      A-33
<PAGE>

     (b) From the Effective Time until the sixth anniversary of the Effective
  Time, the Surviving Corporation shall maintain in effect, for the benefit
  of the Indemnified Persons with respect to acts or omissions occurring
  prior to the Effective Time, the existing policy of directors' and
  officers' liability insurance maintained by the Company as of the date of
  this Agreement in the form disclosed by the Company to Parent prior to the
  date of this Agreement (the "Existing Policy"); provided, however, that (i)
  the Surviving Corporation may substitute for the Existing Policy a policy
  or policies of comparable coverage, and (ii) the Surviving Corporation
  shall not be required to pay annual premiums for the Existing Policy (or
  for any substitute policies) in excess of $475,000 in the aggregate. In the
  event any future annual premiums for the Existing Policy (or any substitute
  policies) exceed $475,000 in the aggregate, the Surviving Corporation shall
  be entitled to reduce the amount of coverage of the Existing Policy (or any
  substitute policies) to the amount of coverage that can be obtained for a
  premium equal to $475,000.

   5.7 Pooling of Interests. Each of the Company and Parent agrees (and the
Company agrees to cause the Acquired Corporations) (a) not to take any action
during the Pre-Closing Period that, to the best of the knowledge of the Company
or to the actual knowledge of the officers of Parent, as the case may be, would
adversely affect the ability of Parent to account for the Merger as a "pooling
of interests," and (b) to use all reasonable efforts to attempt to ensure that
none of its "affiliates" (as that term is used in Rule 145 under the Securities
Act) takes any action that could adversely affect the ability of Parent to
account for the Merger as a "pooling of interests." Each of the Company and
Parent agrees to provide to PricewaterhouseCoopers LLP such letters as shall be
reasonably requested by PricewaterhouseCoopers LLP in connection with the
letters referred to in Sections 6.6(c) and 6.6(d). Parent shall cause its
"affiliates" (as that term is used in Rule 145 under the Securities Act) not to
sell shares of Parent Common Stock prior to the Closing in contravention of
applicable "pooling of interests" accounting rules.

   5.8 Additional Agreements

     (a) Subject to Section 5.8(b), Parent and the Company shall use all
  reasonable efforts to take, or cause to be taken, all actions necessary to
  consummate the Merger and make effective the other transactions
  contemplated by this Agreement. Without limiting the generality of the
  foregoing, but subject to Section 5.8(b), each party to this Agreement (i)
  shall make all filings (if any) and give all notices (if any) required to
  be made and given by such party in connection with the Merger and the other
  transactions contemplated by this Agreement, (ii) shall use all reasonable
  efforts to obtain each Consent (if any) required to be obtained (pursuant
  to any applicable Legal Requirement or Contract, or otherwise) by such
  party in connection with the Merger or any of the other transactions
  contemplated by this Agreement, and (iii) shall use all reasonable efforts
  to lift any restraint, injunction or other legal bar to the Merger. The
  Company shall promptly deliver to Parent a copy of each such filing made,
  each such notice given and each such Consent obtained by the Company during
  the Pre-Closing Period.

     (b) Notwithstanding anything to the contrary contained in this
  Agreement, Parent shall not have any obligation under this Agreement: (i)
  to dispose of or transfer or cause any of its Subsidiaries to dispose of or
  transfer any assets, or to commit to cause any of the Acquired Corporations
  to dispose of any assets; (ii) to discontinue or cause any of its
  Subsidiaries to discontinue offering any product or service, or to commit
  to cause any of the Acquired Corporations to discontinue offering any
  product or service; (iii) to license or otherwise make available, or cause
  any of its Subsidiaries to license or otherwise make available, to any
  Person, any technology, software or other Proprietary Asset, or to commit
  to cause any of the Acquired Corporations to license or otherwise make
  available to any Person any technology, software or other Proprietary
  Asset; (iv) to hold separate or cause any of its Subsidiaries to hold
  separate any assets or operations (either before or after the Closing
  Date), or to commit to cause any of the Acquired Corporations to hold
  separate any assets or operations; (v) to make or cause any of its
  Subsidiaries to make any commitment (to any Governmental Body or otherwise)
  regarding its future operations or the future operations of any of the
  Acquired Corporations; or (vi) to contest any Legal Proceeding relating to
  the Merger if Parent determines in good faith that contesting such Legal
  Proceeding might not be advisable.

                                      A-34
<PAGE>

   5.9 Disclosure. Except in the situation where the Company Board
Recommendation has been withdrawn or modified in a manner adverse to Parent in
accordance with Section 5.2(c), Parent and the Company shall consult with each
other and attempt to agree upon the language of any press release or other
public statement with respect to the Merger or any of the other transactions
contemplated by this Agreement; provided, however, that either party may make
such disclosure as is required by applicable law.

   5.10 Affiliate Agreements. The Company shall use all reasonable efforts to
cause each Person identified in Part 2.20 of the Company Disclosure Schedule
and each other Person who is or becomes (or may be deemed to be) an "affiliate"
(as that term is used in Rule 145 under the Securities Act) of the Company to
execute and deliver to Parent, prior to the date of the mailing of the
Prospectus/Proxy Statement to the Company's stockholders, an Affiliate
Agreement in the form previously approved by Parent. Shares of Parent Common
Stock and shares of Company Common Stock beneficially owned by each "affiliate"
of the Company who has not provided a signed Affiliate Agreement in accordance
with this Section 5.10 shall not be transferable during any period prior to or
after the Effective Time if, as a result of the transfer of any such shares
during any such period, taking into account the nature, extent and timing of
the transfer and similar transfers by all other "affiliates" of Parent and the
Company, the transfer may, in the reasonable judgment of the independent
accountants to Parent, prevent Parent from accounting for the Merger as a
"pooling of interests" in accordance with generally accepted accounting
principles, Accounting Principles Board Opinion No. 16 and all published rules,
regulations and policies of the SEC. Neither Parent nor the Company shall
register, or allow its transfer agent to register, on its books any transfer of
any shares of Parent Common Stock or Company Common Stock of any "affiliate" of
the Company who has not provided a signed Affiliate Agreement in accordance
with this Section 5.10.

   5.11 Tax Matters. At or prior to the filing of the Form S-4 Registration
Statement, the Company and Parent shall execute and deliver to Cooley Godward
LLP and to Wilson Sonsini Goodrich & Rosati, P.C. tax representation letters in
customary form. To the extent requested by Parent or the Company, Parent,
Merger Sub and the Company shall each confirm to Cooley Godward LLP and to
Wilson Sonsini Goodrich & Rosati, P.C. the accuracy and completeness as of the
Effective Time of the tax representation letters delivered pursuant to the
immediately preceding sentence. Parent and the Company shall use all reasonable
efforts prior to the Effective Time to cause the Merger to qualify as a tax
free reorganization under Section 368(a)(1) of the Code. Following delivery of
the tax representation letters pursuant to the first sentence of this Section
5.11, each of Parent and the Company shall use its reasonable efforts to cause
Cooley Godward LLP and Wilson Sonsini Goodrich & Rosati, P.C., respectively, to
deliver to it a tax opinion satisfying the requirements of Item 601 of
Regulation S-K promulgated under the Securities Act. In rendering such
opinions, each of such counsel shall be entitled to rely on the tax
representation letters referred to in this Section 5.11.

   5.12 Letter of the Company's Accountants. The Company shall use all
reasonable efforts to cause to be delivered to Parent a letter of
PricewaterhouseCoopers LLP, dated no more than two business days before the
date on which the Form S-4 Registration Statement becomes effective (and
reasonably satisfactory in form and substance to Parent), that is customary in
scope and substance for letters delivered by independent public accountants in
connection with registration statements similar to the Form S-4 Registration
Statement.

   5.13 Listing. Parent shall use reasonable efforts to cause the shares of
Parent Common Stock being issued in the Merger and issuable upon the exercise
of assumed Company Options and assumed Company Warrants to be approved for
listing (subject to notice of issuance) on the Nasdaq National Market.

   5.14 Resignation of Officers and Directors. The Company shall use all
reasonable efforts to obtain and deliver to Parent at or prior to the Closing
the resignation of each officer and director of each of the Acquired
Corporations.

   5.15 Acknowledgments of Officers. The Company shall use reasonable efforts
to cause each officer of the Company of the rank of Vice President or above to
execute and deliver to the Company and Parent, at or

                                      A-35
<PAGE>

prior to the Closing, a written acknowledgment in the form previously agreed to
by Parent (clarifying the terms of vesting acceleration of such officer's
outstanding options).

Section 6. Conditions Precedent to Obligations of Parent and Merger Sub

   The obligations of Parent and Merger Sub to effect the Merger and otherwise
consummate the transactions contemplated by this Agreement are subject to the
satisfaction, at or prior to the Closing, of each of the following conditions:

   6.1 Accuracy of Representations.

     (a) The representations and warranties of the Company contained in this
  Agreement shall have been accurate in all respects as of the date of this
  Agreement, except that any inaccuracies in such representations and
  warranties will be disregarded if the circumstances giving rise to all such
  inaccuracies (considered collectively) do not constitute, and would not
  reasonably be expected to have, a Material Adverse Effect on the Acquired
  Corporations; provided, however, that, for purposes of determining the
  accuracy of such representations and warranties, (i) all "Material Adverse
  Effect" qualifications and other materiality qualifications contained in
  such representations and warranties shall be disregarded and (ii) any
  update of or modification to the Company Disclosure Schedule made or
  purported to have been made after the date of this Agreement shall be
  disregarded.

  Adverse Effect on the Acquired Corporations; provided, however, that, for

  warranties, (i) all "Material Adverse Effect" qualifications and other

     (a) by mutual written consent of Parent and the Company;

     (b) by either Parent or the Company if the Merger shall not have been

  obligation required to be performed by such party at or prior to the
  Effective Time, and (B) the Company shall not be permitted to terminate
  this Agreement pursuant to this Section 8.1(d) unless the Company shall

  the Required Company Stockholder Vote) if a Triggering Event shall have
  occurred;

  Agreement such that the condition set forth in Section 6.1(a) would not be

  contained in this Agreement shall have become inaccurate as of a date
  subsequent to the date of this Agreement (as if made on such subsequent

  contained in this Agreement shall be inaccurate as of the date of this
  Agreement such that the condition set forth in Section 7.1(a) would not be
  satisfied, (ii) any of Parent's representations and warranties contained in
  this Agreement shall have become inaccurate as of a date subsequent to the
  date of this Agreement (as if made on such subsequent date) such that the
  condition set forth in Section 7.1(b) would not be satisfied (it being
  understood that, for purposes of determining the accuracy of such
  representations and warranties as of a date subsequent to the date of this
  Agreement, all "Material Adverse Effect" qualifications and other
  materiality qualifications contained in such representations and warranties
  shall be disregarded), or (iii) if any of Parent's covenants contained in
  this Agreement shall have been breached such that the condition set forth
  in Section 7.2 would not be satisfied; provided, however, that if an
  inaccuracy in Parent's representations and warranties or a breach of a
  covenant by Parent is curable by Parent and Parent is continuing to

     (a) No failure on the part of any party to exercise any power, right,

  remedy; and no single or partial exercise of any such power, right,
  privilege or remedy shall preclude any other or further exercise thereof or
  of any other power, right, privilege or remedy.

  this Agreement, or any power, right, privilege or remedy under this
  Agreement, unless the waiver of such claim, power, right, privilege or

  delivered on behalf of such party; and any such waiver shall not be
  applicable or have any effect except in the specific instance in which it
  is given.

PERSONAL AND CONFIDENTIAL

                                                                January 12, 2000

Board of Directors
Etec Systems, Inc.
26460 Corporate Avenue
Hayward, CA 94545

Gentlemen:

   You have requested our opinion as to the fairness from a financial point of
view to the holders of the outstanding shares of Common Stock, par value $0.01
per share (the "Company Shares"), of Etec Systems, Inc. (the "Company"), of the
exchange ratio of 0.649 shares of Common Stock, par value $0.01 per share (the
"Applied Materials Common Stock"), of Applied Materials, Inc. ("Applied
Materials") to be received for each Company Share (the "Exchange Ratio")
pursuant to the Agreement and Plan of Reorganization, dated as of January 12,
2000, among Applied Materials, Boston Acquisition Sub, Inc., a wholly-owned
subsidiary of Applied Materials, and the Company (the "Agreement").

   Goldman, Sachs & Co., as part of its investment banking business, is
continually engaged in the valuation of businesses and their securities in
connection with mergers and acquisitions, negotiated underwritings, competitive
biddings, secondary distributions of listed and unlisted securities, private
placements and valuations for estate, corporate and other purposes. We are
familiar with the Company having acted as its financial advisor in connection
with, and having participated in certain of the negotiations leading to, the
Agreement. We also have provided certain investment banking services to Applied
Materials from time to time, including having acted as managing underwriter in
connection with the public offering of $200 million aggregate principal amount
of 6.75% Notes due 2007 and $200 million aggregate principal amount of 7.125%
Notes due 2017 in October 1997. Goldman, Sachs & Co. provides a full range of
financial advisory and securities services and, in the course of its normal
trading activities, may from time to time effect transactions and hold
securities, including derivative securities, of the Company or Applied
Materials for its own account and for the accounts of customers.

   In connection with this opinion, we have reviewed, among other things, the
Agreement; Annual Reports to Stockholders and Annual Reports on Form 10-K of
the Company for the four fiscal years ended July 31, 1999 and of Applied
Materials for the five fiscal years ended October 31, 1998, certain interim
reports to stockholders and Quarterly Reports on Form 10-Q of the Company and
Applied Materials; certain other communications from the Company and Applied
Materials to their respective stockholders; and certain internal financial
analyses and forecasts for the Company prepared by its management. We also have
held discussions with members of the senior management of the Company and
Applied Materials regarding their assessment of the strategic rationale for,
and the potential benefits of, the transaction contemplated by the Agreement
and the past and current business operations, financial condition and future
prospects of their respective companies. In addition, we have reviewed the
reported price and trading activity for the Company Shares and the Applied
Materials Common Stock, compared certain financial and stock market information
for the Company and Applied Materials with similar information for certain
other companies the securities of which are publicly traded, reviewed the
financial terms of certain recent business combinations in the semiconductor
equipment industry specifically and in other industries generally and performed
such other studies and analyses as we considered appropriate.

   We have relied upon the accuracy and completeness of all of the financial
and other information discussed with or reviewed by us and have assumed such
accuracy and completeness for purposes of rendering this

                                      B-1
<PAGE>

opinion. As you are aware, Applied Materials did not make available to us its
projections of expected future financial performance. Accordingly, our review
of such matters was limited to discussions with members of the senior
management of Applied Materials regarding certain research analyst estimates
for Applied Materials. In addition, we have not made an independent evaluation
or appraisal of the assets and liabilities of the Company or Applied Materials
or any of their subsidiaries and we have not been furnished with any such
evaluation or appraisal. We were not requested to solicit, and did not solicit,
interest from other parties with respect to an acquisition of or other business
combination with the Company. We have also taken into account the Company's
expectations regarding the accounting treatment of the transaction. Our
advisory services and the opinion expressed herein are provided for the
information and assistance of the Board of Directors of the Company in
connection with its consideration of the transaction contemplated by the
Agreement and such opinion does not constitute a recommendation as to how any
holder of Shares should vote with respect to such transaction.

   Based upon and subject to the foregoing and based upon such other matters as
we consider relevant, it is our opinion that as of the date hereof the Exchange
Ratio pursuant to the Agreement is fair from a financial point of view to the
holders of Company Shares.

                                          Very truly yours,

                                                /s/ Goldman, Sachs & Co.

Reorganization Agreement.

   2. Grant of Option. The Company hereby grants to the Grantee an irrevocable
option (the "Option") to purchase, out of the authorized but unissued Company
Common Stock, a number of shares of Company Common Stock equal to up to 19.9%
of the number of shares of Company Common Stock outstanding as of the date
hereof (the shares of Company Common Stock purchasable pursuant to the Option,
as adjusted as set forth herein, the "Option Shares"), at a price per Option
Share equal to the Exercise Price. For purposes of this Option Agreement, the
applicable "Exercise Price" shall be equal to $82.46.

   3. Term. The Option shall terminate on the earliest of the following dates
(the "Termination Date"): (a) the date on which the Merger becomes effective;
(b) the date on which the Reorganization Agreement is validly terminated
pursuant to Section 8.1 thereof, if an Exercise Event (as defined in Section
4(b)) shall not have occurred on or prior to such date; or (c) the 180th day
after the date on which the Grantee receives written notice from the Company
of the occurrence of an Exercise Event; provided, however, that if an Exercise
Event occurs, and if, by reason of any applicable Legal Requirement, order,
judgment, decree or other legal impediment, the Option cannot be exercised on
the 180th day after the date on which the Grantee receives the written notice
referred to in clause "(c)" of this sentence, then the Termination Date shall
be extended until the date 10 business days after the date on which such
impediment is removed. The rights of the Grantee and the obligations of the
Company set forth in Sections 7 and 8 shall not terminate on the Termination
Date, but shall survive the Termination Date as provided in those Sections.

   4. Exercise of Option.

     (a) The Grantee may exercise the Option, in whole or in part, at any
  time and from time to time on or before the Termination Date following the
  occurrence of an Exercise Event. If the Grantee exercises the Option with
  respect to any Option Shares prior to the Termination Date, then,
  notwithstanding anything to the contrary contained in this Option
  Agreement, the Grantee shall be entitled to purchase such Option Shares in
  accordance with the terms of this Option Agreement after the Termination
  Date.

     (b) For purposes of this Option Agreement, an "Exercise Event" shall be
  deemed to have occurred:

       (i) immediately prior to the Company being required to pay a
    termination fee to the Grantee pursuant to Section 8.3 (c) of the
    Reorganization Agreement; or

                                      C-1
<PAGE>

       (ii) if the Grantee shall have terminated the Reorganization
    Agreement pursuant to Section 8.1(e) thereof or the Grantee shall have
    delivered to the Company a written notice containing the Grantee's
    irrevocable determination to terminate the Reorganization Agreement if
    a final vote of the Company's stockholders on a proposal to adopt the
    Reorganization Agreement is taken and the Company's stockholders do not
    adopt the Reorganization Agreement by the Required Company Stockholder
    Vote.

     (c) To exercise the Option with respect to any Option Shares, the
  Grantee shall deliver to the Company a written notice (an "Exercise
  Notice") specifying: (i) the number of Option Shares the Grantee will
  purchase; (ii) the place at which such Option Shares are to be purchased;
  and (iii) the date on which such Option Shares are to be purchased, which
  shall not be sooner than two business days nor later than twenty business
  days after the date of delivery of such Exercise Notice to the Company.
  (The date of delivery of such Exercise Notice to the Company is referred to
  as the applicable "Notice Date," and the Option shall be deemed to have
  been validly exercised on such Notice Date with respect to the Option
  Shares referred to in such Exercise Notice.) The closing of the purchase of
  such Option Shares (the applicable "Closing") shall take place at the place
  specified in the Exercise Notice and on the date specified in the Exercise
  Notice (the applicable "Closing Date"); provided, however, that: (A) if
  such purchase cannot be consummated on such Closing Date by reason of any
  applicable Legal Requirement, order, judgment, decree or other legal
  impediment, then the Grantee may extend the Closing Date to a date not more
  than 10 business days after the date on which such impediment is removed;
  and (B) if prior notification to or approval of any Governmental Body is
  required, or if any waiting period must expire or be terminated, in
  connection with such purchase, then (1) the Company shall promptly cause to
  be filed the required notice or application for approval and shall
  expeditiously process such notice or application, (2) the Company shall
  cooperate with the Grantee in the filing of any such notice or application
  required to be filed by the Grantee and in the obtaining of any such
  approval required to be obtained by the Grantee, and (3) the Grantee may
  extend the Closing Date to a date not more than 10 business days after the
  latest date on which any required notification has been made, any required
  approval has been obtained or any required waiting period has expired or
  been terminated.

   5. Payment and Delivery of Certificate.

     (a) On each Closing Date, the Grantee shall pay to the Company in
  immediately available funds an amount equal to the applicable Exercise
  Price multiplied by the number of Option Shares to be purchased by the
  Grantee from the Company on such Closing Date.

     (b) At each Closing, simultaneously with the delivery of immediately
  available funds as provided in Section 5(a), the Company shall deliver to
  the Grantee a certificate representing the Option Shares being purchased at
  such Closing. The Company represents, warrants and covenants that such
  Option Shares will be duly authorized, validly issued, fully paid,
  nonassessable and free and clear of all Encumbrances, except as may be
  specifically provided in this Option Agreement.

     (c) The certificate representing the Option Shares delivered at each
  Closing shall be endorsed with a restrictive legend that shall read
  substantially as follows:

    THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
    UNDER THE SECURITIES ACT OF 1933 AND MAY NOT BE OFFERED, SOLD OR
    OTHERWISE TRANSFERRED UNLESS REGISTERED UNDER SAID ACT OR UNLESS AN
    EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF SAID ACT IS AVAILABLE.

  If at any time the Grantee delivers to the Company evidence (in the form of
  a copy of a letter from the staff of the SEC or an opinion of counsel
  reasonably satisfactory to the Company, or in some other form) that the
  legend referred to above is not required for purposes of the Securities
  Act, then the Company shall promptly replace such certificate with a
  certificate that does not include such legend.

                                      C-2

   6. Adjustment Upon Changes in Capitalization, Etc.

     (a) If the outstanding shares of Company Common Stock are changed into a
  different number or class of shares by reason of any stock split, division
  or subdivision of shares, stock dividend, reverse stock split,
  reclassification, recapitalization or other similar transaction, then the
  type and number of shares or securities subject to the Option, the
  applicable Exercise Price, the Designated Price (as defined in
  Section 7(c)) and the other numbers and dollar amounts referred to in this
  Option Agreement shall be adjusted appropriately, and the Company shall
  ensure that proper provision is made in the agreements and other documents
  governing such transaction so that the Grantee shall receive upon exercise
  of the Option the same class and number of outstanding shares or other
  securities or property that the Grantee would have received in respect of
  the Company Common Stock if the Option had been exercised immediately prior
  to such transaction or the record date for determining stockholders
  entitled to participate in such transaction, as applicable. If any
  additional shares of Company Common Stock are issued after the date of this
  Option Agreement (other than pursuant to a transaction described in the
  first sentence of this Section 6(a)), then the number of shares of Company
  Common Stock then remaining subject to the Option shall be increased to the
  number by which (i) 19.9% of the number of shares of Company Common Stock
  outstanding after the issuance of such additional shares exceeds (ii) the
  number of shares (adjusted in accordance with the first sentence of this
  Section 6(a)) previously issued to the Grantee upon exercise of the Option.

     (b) If the Company shall enter into an agreement (i) to consolidate,
  exchange shares or merge with any Person, other than the Grantee or one of
  the Grantee's subsidiaries, and, in the case of a merger, shall not be the
  continuing or surviving corporation, (ii) to permit any Person, other than
  the Grantee or one of the Grantee's subsidiaries, to merge into the Company
  and the Company shall be the continuing or surviving corporation, but, in
  connection with such merger, the then outstanding shares of Company Common
  Stock shall be changed into or exchanged for stock or other securities of
  the Company or any other Person or cash or any other property, or the
  shares of Company Common Stock outstanding immediately before such merger
  shall after such merger represent less than 50% of the common shares and
  common share equivalents of the Company outstanding immediately after the
  merger, or (iii) to sell, lease or otherwise transfer all or substantially
  all of its assets to any Person, other than the Grantee or one of the
  Grantee's subsidiaries, then, and in each such case, the Company shall
  ensure that proper provision is made in the agreements and other documents
  governing such transaction so that the Option shall, upon the consummation
  of such transaction, become exercisable for the stock, securities, cash or
  other property that would have been received by the Grantee if the Grantee
  had exercised the Option immediately prior to such transaction or the
  record date for determining the stockholders entitled to participate in
  such transaction, as appropriate.

     (c) The provisions of Sections 7 and 8 shall apply (with appropriate
  adjustments) to any securities for which the Option becomes exercisable
  pursuant to this Section 6.

   7. Repurchase at the Election of the Grantee.

     (a) If, at any time during the period commencing upon the occurrence of
  the first Exercise Event and ending on the 180th day after such occurrence,
  the Grantee delivers to the Company a notice stating that the Grantee is
  exercising its rights under this Section 7, then the Company shall
  repurchase from the Grantee (i) that portion of the Option that then
  remains unexercised, (ii) all of the shares of Company Common Stock
  beneficially owned by the Grantee that were previously purchased by the
  Grantee upon exercise of the Option, and (iii) the Grantee's right to
  receive all Option Shares with respect to which the Option was previously
  exercised but which have not yet been issued and delivered to the Grantee.
  (The date on which the Grantee delivers such notice to the Company is
  referred to as the "Request Date.") Such repurchase shall be at an
  aggregate price (the "Repurchase Consideration") equal to the sum of:

       (i) the aggregate number of Option Shares with respect to which the
    Option has been exercised on or prior to the Request Date and which are
    beneficially owned by the Grantee, multiplied by the Designated Price;

                                      C-3
<PAGE>

       (ii) the aggregate number of Option Shares with respect to which the
    Option has previously been exercised but which have not yet been issued
    and delivered to the Grantee, multiplied by the Designated Price (it
    being understood that nothing in this Section 7 (a) (ii) or elsewhere
    in this Option Agreement shall limit the Grantee's obligation to pay to
    the Company the applicable Exercise Price for such Option Shares
    pursuant to Sections 4 and 5); and

       (iii) the number of Option Shares with respect to which the Option
    has not been exercised on or prior to the Request Date multiplied by
    the amount (if any) by which the Designated Price, exceeds the
    applicable Exercise Price.

     (b) If the Grantee exercises its rights under this Section 7, then the
  Company shall, within two business days after the Request Date, pay the
  Repurchase Consideration to the Grantee in immediately available funds, and
  the Grantee shall thereupon surrender to the Company the certificate or
  certificates evidencing the shares of Company Common Stock repurchased by
  the Company pursuant to this Section 7.

     (c) For purposes of this Option Agreement, the "Designated Price" means
  the highest of (i) the highest purchase price per share paid after the date
  of this Option Agreement and on or prior to the Request Date pursuant to
  any tender or exchange offer made for shares of Company Common Stock,
  (ii) the highest price per share paid or to be paid by any Person for
  shares of Company Common Stock pursuant to any agreement contemplating a
  merger or other business combination transaction involving the Company that
  was entered into after the date of this Option Agreement and on or prior to
  the Request Date, (iii) the average of the highest bid prices per share of
  Company Common Stock as quoted on The Nasdaq National Market (or if Company
  Common Stock is not quoted on The Nasdaq National Market, the highest bid
  price per share of Company Common Stock as quoted on any other market
  comprising a part of The Nasdaq Stock Market or, if the shares of Company
  Common Stock are not quoted thereon, on the principal trading market (as
  defined in Regulation M under the Exchange Act) on which such shares are
  traded as reported by a recognized source) during the 10-day period ending
  on the Request Date, or (iv) the highest Exercise Price paid or payable for
  any Option Shares. If any portion of the consideration paid or to be paid
  pursuant to clause (i) or (ii) of the preceding sentence is in a form other
  than cash, then the value of the non-cash portion of such consideration
  shall be determined in good faith by an independent nationally recognized
  investment banking firm selected by the Grantee and reasonably acceptable
  to the Company.

   8. Registration Rights.

     (a) The Company shall, if requested by the Grantee at any time and from
  time to time within two years after the first exercise of the Option (the
  "Registration Period"), as expeditiously as practicable, prepare, file and
  cause to be declared effective up to two registration statements under the
  Securities Act (including, at the sole discretion of the Company, a "shelf"
  registration statement under Rule 415 under the Securities Act or any
  successor provision), if registration under the Securities Act is (in the
  Grantee's good faith judgment) necessary or desirable in order to permit
  the offering, sale and delivery, in accordance with the intended method of
  sale or other disposition stated by the Grantee, of any or all shares of
  Company Common Stock or other securities that have been acquired or are
  issuable upon exercise of the Option. Without the Grantee's prior written
  consent, no other securities may be included in any such registration
  statement. The Company shall use all reasonable efforts to cause each such
  registration statement to become effective, to obtain all consents or
  waivers of other parties that are required therefor and to keep such
  registration statement effective for such period as may be as reasonably
  necessary to effect such sale or other disposition. In addition, the
  Company shall use all reasonable efforts to register such shares or other
  securities under any applicable state securities laws. The obligations of
  the Company hereunder to file a registration statement and to maintain its
  effectiveness may be suspended for one or more periods of time not
  exceeding 45 days in the aggregate if the Board of Directors of the Company
  shall have determined in good faith that the filing of such registration
  statement or the maintenance of its effectiveness would require disclosure
  of material nonpublic information and that the disclosure thereof

                                      C-4
<PAGE>

  would materially and adversely affect the Company. For purposes of
  determining whether two requests have been made under this Section 8, only
  requests relating to a registration statement that has become effective
  under the Securities Act shall be counted.

     (b) The expenses associated with the preparation and filing of any such
  registration statement pursuant to this Section 8 and any sale covered
  thereby (including any fees related to blue sky qualifications and filing
  fees in respect of the National Association of Securities Dealers, Inc.)
  ("Registration Expenses") shall be for the account of the Company (except
  for underwriting discounts or commissions or brokers' fees in respect to
  shares to be sold by the Grantee and the fees and disbursement of the
  Grantee's counsel).

     (c) The Grantee shall provide all information reasonably requested by
  the Company for inclusion in any registration statement to be filed
  hereunder. If during the Registration Period the Company shall propose to
  register under the Securities Act the offering, sale and delivery of
  Company Common Stock for cash pursuant to a firm commitment underwriting,
  it shall, in addition to the Company's other obligations under this Section
  8, allow the Grantee the right to participate in such registration provided
  that the Grantee participates in the underwriting; provided, however, that,
  if the managing underwriter of such offering advises the Company in writing
  that in its opinion the number of shares of Company Common Stock requested
  to be included in such registration exceeds the number that can be sold in
  such offering, the Company shall, after fully including therein all
  securities to be sold by the Company, include the shares requested to be
  included therein by Grantee pro rata (based on the number of shares
  intended to be included therein) with the shares intended to be included
  therein by Persons other than the Company. In connection with any offering,
  sale and delivery of Company Common Stock pursuant to a registration
  effected pursuant to this Section 8, the Company and the Grantee shall
  provide each other and each underwriter of the offering with customary
  representations, warranties and covenants, including covenants of
  indemnification and contribution.

   9. Profit Limitation.

     (a) Notwithstanding any other provision in this Agreement, in no event
  shall the Grantee's Total Profit (as defined below) exceed $54,000,000.00
  (the "Maximum Profit") and, if the Grantee's Total Profit otherwise would
  exceed the Maximum Profit, the Grantee, at its sole discretion shall either
  (i) reduce the number of Option Shares subject to the Option, (ii) deliver
  to the Company for cancellation Option Shares (or other securities into
  which such Option Shares are converted or exchanged) previously purchased
  by the Grantee, (iii) pay cash to the Company, or (iv) any combination of
  the foregoing, so that the Grantee's actually realized Total Profit shall
  not exceed the Maximum Profit after taking into account the foregoing
  actions.

     (b) For purposes of this Agreement, "Total Profit" shall mean: (i) the
  aggregate amount (before taxes) of (A) any excess of (x) the net cash
  amounts or fair market value of any property received by the Grantee
  pursuant to a sale of Option Shares (or securities into which such shares
  are converted or exchanged) over (y) the Grantee's aggregate purchase price
  for such Option Shares (or other securities), plus (B) any amounts received
  by the Grantee on the repurchase of the Option by the Company pursuant to
  Section 7, plus (C) any termination fee paid by the Company and received by
  the Grantee pursuant to the Reorganization Agreement, minus (ii) the
  amounts of any cash previously paid by the Grantee to the Company pursuant
  to this Section 9 plus the value of the Option Shares (or other securities)
  previously delivered by the Grantee to the Company for cancellation
  pursuant to this Section 9.

     (c) For purposes of Section 9(a) and clause (ii) of Section 9(b), the
  value of any Option Shares delivered by the Grantee to the Company shall be
  the Designated Price of such Option Shares.

   10. Listing. If, at the time of the occurrence of an Exercise Event, the
Company Common Stock (or any other class of securities subject to the Option)
is then listed on The Nasdaq National Market or on any other market or
exchange, then the Company, upon the occurrence of such Exercise Event, shall
promptly file an application to list on The Nasdaq National Market and on such
other market or exchange the shares of the

                                      C-5
<PAGE>

Company Common Stock (or other securities then subject to the Option), and
shall use its best efforts to cause such application to be approved as promptly
as practicable.

   11. Replacement of Agreement. Upon receipt by the Company of evidence
reasonably satisfactory to it of the loss, theft, destruction or mutilation of
this Option Agreement, and (in the case of loss, theft or destruction) of
reasonably satisfactory indemnification, and upon surrender and cancellation of
this Option Agreement, if mutilated, the Company will execute and deliver a new
Option Agreement of like tenor and date.

   12. Investment Representations. The Option and any Option Shares which the
Grantee may hereafter acquire are being acquired by the Grantee for its own
account, for investment and not with a view to the distribution or resale
thereof, except in compliance with the Securities Act of 1933, as amended, and
applicable state securities and blue sky laws. The Grantee has sufficient
knowledge and experience in investing in securities similar to the Option and
to the Option Shares so as to be able to evaluate the risks and merits of any
investment in the Option and in the Option Shares and is able financially to
bear the risks thereof, including a complete loss of its investment.

   13. Miscellaneous.

     (a) Waiver. No failure on the part of any party to exercise any power,
  right, privilege or remedy under this Option Agreement, and no delay on the
  part of any party in exercising any power, right, privilege or remedy under
  this Option Agreement, shall operate as a waiver of such power, right,
  privilege or remedy; and no single or partial exercise of any such power,
  right, privilege or remedy shall preclude any other or further exercise
  thereof or of any other power, right, privilege or remedy. No party shall
  be deemed to have waived any claim arising out of this Option Agreement, or
  any power, right, privilege or remedy under this Option Agreement, unless
  the waiver of such claim, power, right, privilege or remedy is expressly
  set forth in a written instrument duly executed and delivered on behalf of
  such party; and any such waiver shall not be applicable or have any effect
  except in the specific instance in which it is given.

     (b) Notices. Any notice or other communication required or permitted to
  be delivered to any party under this Option Agreement shall be in writing
  and shall be deemed properly delivered, given and received (a) when
  delivered by hand, or (b) two business days after sent by registered mail
  or, by courier or express delivery service or by facsimile to the address
  or facsimile telephone number set forth beneath the name of such party
  below (or to such other address or facsimile telephone number as such party
  shall have specified in a written notice given to the other parties

     (c) Entire Agreement; Counterparts. This Option Agreement and the
  agreements referred to herein constitute the entire agreement and supersede
  all prior agreements and understandings, both written and oral, between the
  parties with respect to the subject matter hereof and thereof. This Option
  Agreement may be executed in several counterparts, each of which shall be
  deemed an original and all of which shall constitute one and the same
  instrument.

     (d) Binding Effect; Benefit; Assignment. This Option Agreement shall be
  binding upon, and shall be enforceable by and inure solely to the benefit
  of, the parties hereto and their respective successors and assigns;
  provided, however, that neither this Option Agreement nor any of the
  Company's rights, interest or obligations hereunder may be assigned by the
  Company without the prior written consent of the Grantee, and any attempted
  assignment of this Option Agreement or any of such rights, interest or
  obligations by the Company without such consent shall be void and of no
  effect. Nothing in this Option Agreement, express or implied, is intended
  to or shall confer upon any Person (other than the parties hereto and the
  Grantee's successors and assigns) any right, benefit or remedy of any
  nature whatsoever under or by reason of this Option Agreement.

     (e) Amendment and Modification. This Option Agreement may be amended
  with the approval of the respective boards of directors of the Company and
  the Grantee at any time. This Option Agreement may not be amended except by
  an instrument in writing signed on behalf of each of the parties hereto.

     (f) Further Actions. The Company agrees to cooperate fully with the
  Grantee and to execute and deliver such further documents, certificates,
  agreements and instruments and to take such other actions as may be
  reasonably requested by the Grantee to evidence or reflect the transactions
  contemplated by this Option Agreement and to carry out the intent and
  purposes of this Option Agreement.

     (g) Headings. The bold-faced headings contained in this Option Agreement
  are for convenience of reference only, shall not be deemed to be a part of
  this Option Agreement and shall not be referred to in connection with the
  construction or interpretation of this Option Agreement.

     (h) Applicable Law; Jurisdiction. This Option Agreement shall be
  governed by, and construed in accordance with, the laws of the State of
  Nevada, regardless of the laws that might otherwise govern under applicable
  principles of conflicts of laws thereof. In any action between any of the
  parties arising out of or relating to this Option Agreement or any of the
  transactions contemplated by this Option Agreement: (a) each of the parties
  irrevocably and unconditionally consents and submits to the jurisdiction
  and venue of the state and federal courts located in the States of
  California and Nevada; (b) each of the parties irrevocably waives the right
  to trial by jury; and (c) each of the parties irrevocably consents to
  service of process by first class certified mail, return receipt requested,
  postage prepaid, to the address at which such party is to receive notice in
  accordance with Section 12(b).

     (i) Severability. If any term, provision, covenant or restriction
  contained in this Option Agreement is held by a court of competent
  jurisdiction or other authority to be invalid, void, unenforceable or
  against its regulatory policy, the remainder of the terms, provisions,
  covenants and restrictions contained in this Option Agreement shall remain
  in full force and effect and shall in no way be affected, impaired or
  invalidated.

     (j) Specific Performance. The Company agrees that (i) in the event of
  any breach or threatened breach by the Company of any covenant, obligation
  or other provision set forth in this Option Agreement, the Grantee shall be
  entitled (in addition to any other remedy that may be available to it), to
  (A) a decree or order of specific performance or mandamus to enforce the
  observance and performance of such covenant, obligation or other provision,
  and (B) an injunction restraining such breach or threatened breach, and
  (ii) neither the Grantee nor any other Person shall be required to provide
  any bond or other security in connection with any such decree, order or
  injunction or in connection with any related action or proceeding.

     (k) Attorneys' Fees. In any action at law or suit in equity to enforce
  this Option Agreement or the rights of any of the parties hereunder, the
  prevailing party in such action or suit shall be entitled to receive

                                      C-7
<PAGE>

  a reasonable sum for its attorneys' fees and all other reasonable costs and
  expenses incurred in such action or suit.

     (l)  Non-Exclusivity. The rights and remedies of the Grantee under this
  Option Agreement are not exclusive of or limited by any other rights or
  remedies which it may have, whether at law, in equity, by contract or
  otherwise, all of which shall be cumulative (and not alternative). Without
  limiting the generality of the foregoing, the rights and remedies of the
  Grantee under this Option Agreement, and the obligations and liabilities of
  the Company under this Option Agreement, are in addition to their
  respective rights, remedies, obligations and liabilities under all
  applicable Legal Requirements and under the Reorganization Agreement. The
  covenants and obligations of the Company set forth in this Option Agreement
  shall be construed as independent of any other agreement or arrangement
  between the Company, on the one hand, and the Grantee, on the other. The
  existence of any claim or cause of action by the Company against the
  Grantee shall not constitute a defense to the enforcement of any of such
  covenants or obligations against the Company.

                 (Remainder of page intentionally left blank.)

Agreement is separable from every other part of such provision.

   8.5 Entire Agreement. This Voting Agreement, the Proxy and any other

   8.6 Assignment; Binding Effect. Except as provided herein, neither this

breach by Stockholder of any covenant or obligation contained in this Voting
Agreement or in the Proxy, Parent shall be entitled (in addition to any other
remedy that may be available to it, including monetary damages) to seek and

it may have, whether at law, in equity, by contract or otherwise, all of which
shall be cumulative (and not alternative). Without limiting the generality of
the foregoing, the rights and remedies of Parent under this Voting Agreement,
and the obligations and liabilities of Stockholder under this Voting Agreement,
are in addition to their respective rights, remedies, obligations and
liabilities under common law requirements and under all applicable statutes,
rules and regulations. Nothing in this Voting Agreement shall limit any of
Stockholder's obligations, or the rights or remedies of Parent, under any
Affiliate Agreement between Parent and Stockholder; and nothing in any such
Affiliate Agreement shall limit any of Stockholder's obligations, or any of the
rights or remedies of Parent, under this Voting Agreement.

   8.13 Waiver. No failure on the part of Parent to exercise any power, right,
privilege or remedy under this Voting Agreement, and no delay on the part of
Parent in exercising any power, right, privilege or remedy under this Voting
Agreement, shall operate as a waiver of such power, right, privilege or remedy;
and no single or partial exercise of any such power, right, privilege or remedy
shall preclude any other or further exercise thereof or of any other power,
right, privilege or remedy. Parent shall not be deemed to have waived any claim
available to Parent arising out of this Voting Agreement, or any power, right,
privilege or remedy of Parent under this Voting Agreement, unless the waiver of
such claim, power, right, privilege or remedy is expressly set forth in a
written instrument duly executed and delivered on behalf of Parent; and any
such waiver shall not be applicable or have any effect except in the specific
instance in which it is given.

                           FORM OF IRREVOCABLE PROXY

   The undersigned stockholder of Etec Systems, Inc., a Nevada corporation (the
"Company"), hereby irrevocably (to the fullest extent permitted by law)
appoints and constitutes Nancy H. Handel, Alexander Meyer and Applied
Materials, Inc., a Delaware corporation ("Parent"), and each of them, the
attorneys and proxies of the undersigned with full power of substitution and
resubstitution, to the full extent of the undersigned's rights with respect to
(i) the outstanding shares of capital stock of the Company owned of record by
the undersigned as of the date of this proxy, which shares are specified on the
final page of this proxy, and (ii) any and all other shares of capital stock of
the Company that the undersigned may acquire on or after the date hereof. (The
shares of the capital stock of the Company referred to in clauses "(i)" and
"(ii)" of the immediately preceding sentence are collectively referred to as
the "Shares.") Upon the execution hereof, all prior proxies given by the
undersigned with respect to any of the Shares are hereby revoked, and the
undersigned agrees that no subsequent proxies will be given with respect to any
of the Shares.

   This proxy is irrevocable, is coupled with an interest and is granted in
connection with the Voting Agreement, dated as of the date hereof, between
Parent and the undersigned (the "Voting Agreement"), and is granted in
consideration of Parent entering into the Agreement and Plan of Reorganization,
dated as of the date hereof, among Parent, Boston Acquisition Sub, Inc. and the
Company (the "Reorganization Agreement").

   The attorneys and proxies named above will be empowered, and may exercise
this proxy, to vote the Shares at any time until the earlier to occur of the
valid termination of the Reorganization Agreement or the effective time of the
merger contemplated thereby (the "Merger") at any meeting of the stockholders
of the Company, however called, or in connection with any solicitation of
written consents from stockholders of the Company, in favor of the approval and
adoption of the Reorganization Agreement and the approval of the Merger, and in
favor of each of the other actions contemplated by the Reorganization
Agreement.

   The undersigned may vote the Shares on all other matters.

   This proxy shall be binding upon the heirs, estate, executors, personal
representatives, successors and assigns of the undersigned (including any
transferee of any of the Shares).

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS

   Section 145 of the Delaware General Corporation Law, Article Tenth and
Eleventh of Applied Materials' Certificate of Incorporation, as amended and
indemnification agreements entered into by Applied Materials with its directors
provide for the indemnification of officers, directors, employees and agents
under certain circumstances.

   Set forth below is Article Tenth and Eleventh of Applied Materials'
Certificate of Incorporation, as amended pertaining to indemnification of
officers, directors, employees and agents and insurance:

     "TENTH: A director of the corporation shall not be personally liable to
  the corporation or its stockholders for monetary damages for breach of
  fiduciary duty as a director, except for liability (i) for any breach of
  the director's duty of loyalty to the corporation or its stockholders, (ii)
  for acts or omissions not in good faith or which involve intentional
  misconduct or a knowing violation of law, (iii) under section 174 of the
  Delaware General Corporation Law, or (iv) for any transaction from which
  the director derived an improper personal benefit.

     ELEVENTH: 1. Each person who was or is made a party or is threatened to
  be made a party to or is involved in any action, suit or proceeding,
  whether civil, criminal, administrative or investigative (hereinafter a
  "proceeding"), by reason of the fact that he or she, or a person of whom he
  or she is the legal representative, is or was a director, officer, employee
  or agent, of the corporation or is or was serving at the request of the
  corporation as a director, officer, employee or agent of another
  corporation or of a partnership, joint venture, trust or other enterprise,
  including service with respect to employee benefit plans, whether the basis
  of such proceeding is alleged action in an official capacity as a director,
  officer, employee or agent or in any other capacity while serving as a
  director, officer, employee or agent, shall be indemnified and held
  harmless by the corporation to the fullest extent authorized by the
  Delaware General Corporation Law, against all expense, liability and loss
  (including in settlement) reasonably incurred or suffered by such person in
  connection therewith and such indemnification shall continue as to a person
  who has ceased to be a director, officer, employee or agent and shall inure
  to the benefit of his or her heirs, executors and administrators; provided,
  however, that, except as provided in paragraph 2 hereof, the corporation
  shall indemnify any such person seeking indemnification in connection with
  a proceeding (or part thereof) initiated by such person only if such
  proceeding (or part thereof) was authorized by the Board of Directors of
  the corporation. The right to indemnification conferred in this Article
  shall be a contract right.

     2. If a claim under paragraph 1 of this Article is not paid in full by
  the corporation within 30 days after a written claim has been received by
  the corporation, the claimant may at any time thereafter bring suit against
  the corporation to recover the unpaid amount of the claim and, if
  successful in whole or in part, the claimant shall be entitled to be paid
  also the expense of prosecuting such claim. It shall be a defense to any
  such action (other than an action brought to enforce a claim for expenses
  incurred in defending any proceeding in advance of its final disposition
  where the required undertaking, if any is required, has been tendered to
  the corporation) that the claimant has not met the standards of conduct,
  which make it permissible under the Delaware General Corporation Law for
  the corporation to indemnify the claimant for the amount claimed.

     3. The right to indemnification conferred in this Article shall not be
  exclusive of any other right which any person may have or hereafter acquire
  under any statute, provision of the Certificate of Incorporation, bylaw,
  agreement, vote of stockholders or disinterested directors or otherwise.

     4. The corporation may maintain insurance, at its expense, to protect
  itself and any director, officer, employee or agent of the corporation or
  another corporation, partnership, joint venture, trust or other

                                      II-1
<PAGE>

  enterprise against any such expense, liability or loss, whether or not the
  corporation would have the power to indemnify such person against such
  expense, liability or loss under the Delaware General Corporation Law."

   As authorized by the Delaware General Corporation Law and Applied Materials'
Certificate of Incorporation, as amended, Applied Materials has entered into
indemnification agreements with each of its directors and certain of its
officers whereby Applied Materials has agreed to indemnify such directors and
officers the fullest extent permitted by the Delaware General Corporation Law.
The indemnification agreements require Applied Materials, under certain
circumstances and provided certain conditions are satisfied, to advance
expenses to those directors and certain officers who are parties to the
indemnification agreements in the event they are involved in a proceeding.

   Applied Materials has also purchased liability insurance policies covering
certain directors and officers of Applied Materials indemnifying them against
certain liabilities, including certain liabilities arising under the Securities
Act of 1933.

FINANCIAL STATEMENT SCHEDULE:

   The Financial Statement Schedule has previously been filed as part of
Applied Materials' Form 10-K for the fiscal year ended October 31, 1999.

ITEM 22. UNDERTAKINGS.

   The undersigned Registrant hereby undertakes:

     (1) To file, during any period in which offers or sales are being made,
  a post-effective amendment to this Registration Statement:

       (i) To include any prospectus required in Section 10(a) (3) of the
    Securities Act of 1933;

       (ii) To reflect in the prospectus any facts or events arising after
    the effective date of the Registration Statement (or the most recent
    post-effective amendment thereof) which, individually or in the
    aggregate, represent a fundamental change in the information set forth
    in the Registration Statement;

       (iii) To include any material information with respect to the plan
    of distribution not previously disclosed in the Registration Statement
    or any material change to such information in the Registration
    Statement; provided, however, that paragraphs (1)(i) and (1)(ii) do not
    apply if the information required to be included in a post-effective
    amendment by those paragraphs is contained in periodic reports filed by
    the Registrant pursuant to section 13 or section 15(d) of the
    Securities Exchange Act of 1934 that are incorporated by reference in
    the Registration Statement;

     (2) That, for the purpose of determining any liability under the
  Securities Act of 1933, each such post-effective amendment shall be deemed
  to be a new registration statement relating to the securities offered
  therein, and the offering of such securities at that time shall be deemed
  to be the initial bona fide offering thereof;

     (3) To remove from registration by means of a post-effective amendment
  any of the securities being registered which remain unsold at the
  termination of the offering;

     (4) That, for purposes of determining any liability under the Securities
  Act of 1933, each filing of the Registrant's annual report pursuant to
  section 13(a) or section 15(d) of the Securities Exchange Act of 1934 that
  is incorporated by reference in the Registration Statement shall be deemed
  to be a new registration statement relating to the securities offered
  therein, and the offering of such securities at that time shall be deemed
  to be the initial bona fide offering thereof;

     (5) To respond to requests for information that is incorporated by
  reference into the prospectus pursuant to Items 4, 10(b), 11 or 13 of this
  Form, within one business day of receipt of such request, and to send the
  incorporated documents by first class mail or other equally prompt means.
  This includes information contained in documents filed subsequent to the
  effective date of the Registration Statement through the date of responding
  to the request;


     (6) That, prior to any public reoffering of the securities registered
  hereunder through use of a prospectus which is a part of this Registration
  Statement, by any person or party who is deemed to be an underwriter within
  the meaning of Rule 145(c), the issuer undertakes that such reoffering
  prospectus will contain the information called for by the applicable
  registration form with respect to reofferings by persons who may be deemed
  underwriters, in addition to the information called for by the other Items
  of the applicable form;

     (7) That every prospectus (i) that is filed pursuant to paragraph (6)
  immediately preceding, or (ii) that purports to meet the requirements of
  section 10(a)(3) of the Securities Act and is used in connection with

                                      II-3
<PAGE>

  an offering of securities subject to Rule 415, will be filed as a part of
  an amendment to the registration statement and will not be used until such
  amendment is effective, and that, for purposes of determining any liability
  under the Securities Act, each such post-effective amendment shall be
  deemed to be a new registration statement relating to the securities
  offered therein, and the offering of such securities at that time shall be
  deemed to be the initial bona fide offering thereof; and

     (8) To supply by means of a post-effective amendment all information
  concerning a transaction, and the company being acquired involved therein,
  that was not the subject of and included in the Registration Statement when
  it became effective.

   Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the provisions described under Item 20 above, or
otherwise, the Registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public
policy as expressed in the Act and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than the
payment by the Registrant of expenses incurred or paid by a director, officer
or controlling person of the Registrant in the successful defense of any
action, suit or proceeding) is asserted by such director, officer or
controlling person in connection with the securities being registered, the
Registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate jurisdiction
the question whether such indemnification by it is against public policy as
expressed in the Act and will be governed by the final adjudication of such
issue.

Ladies and Gentlemen:

We have acted as counsel for Applied Materials, Inc., a Delaware corporation
(the "Company") in connection with the merger (the "Merger") and other
transactions contemplated by that certain Agreement and Plan of Reorganization,
dated as of January 12, 2000, by and among the Company, Boston Acquisition Sub,
Inc., a Nevada corporation and a wholly-owned subsidiary of the Company, and
Etec Systems, Inc., a Nevada corporation. This opinion is being furnished in
connection with a Registration Statement on Form S-4 ("Registration Statement")
to be filed by the Company with the Securities and Exchange Commission covering
the offer and sale of 16,235,444 shares of the Company's common stock, $0.01 par
value per share ("Common Stock"), subject to the exercise of options, to be
issued in connection with the Merger.

In rendering this opinion, we have examined the following documents: (i) the
Company's Certificate of Incorporation, as amended and Bylaws, as amended, (ii)
the resolutions adopted by the Board of Directors of the Company on January 12,
2000, (iii) the Registration Statement, and (iv) such other documents, legal
opinions and precedents, corporate and other records of the Company, and
certificates of public officials and officers of the Company that we have deemed
necessary or appropriate to provide a basis for the below opinion.

Based upon and subject to the foregoing, in our opinion, the shares of Common
Stock of the Company which are being offered and sold by the Company pursuant to
the Registration Statement, when sold in the manner and for the consideration
contemplated by the Registration Statement, will be legally issued, fully paid
and non-assessable.

We consent to the filing of this opinion as an Exhibit to the Registration
Statement and to the reference to our firm under the heading "Legal Matters."


Very truly yours,

Cooley Godward LLP

                        [COOLEY GODWARD LLP LETTERHEAD]

February 8, 2000

Applied Materials, Inc.
3050 Bowers Avenue
Santa Clara, ,CA 95054

Ladies and Gentlemen:

This opinion is being delivered to you in connection with the Form S-4
Registration Statement (the "Registration Statement") filed pursuant to the
Agreement and Plan of Reorganization, dated as of January 12, 2000 (the
"Reorganization Agreement"), among Applied Materials, Inc., a Delaware
corporation ("Parent"), Boston Acquisition Sub, Inc., a Nevada corporation and
wholly-owned subsidiary of Parent ("Merger Sub"), and Etec Systems, Inc., a
Nevada corporation (the "Company").

Except as otherwise provided, capitalized terms used but not defined herein
shall have the meanings set forth in the Reorganization Agreement. All section
references, unless otherwise indicated, are to the Internal Revenue Code of
1986, as amended (the "Code").

We have acted as counsel to Parent and Merger Sub in connection with the Merger.
As such, and for the purpose of rendering this opinion, we have examined, and
are relying upon (without any independent investigation or review thereof) the
truth and accuracy, at all relevant times, of the statements, covenants,
representations and warranties contained in the following documents (including
all exhibits and schedules attached thereto):

     (a)  the Reorganization Agreement;

     (b)  those certain tax representation letters delivered to us by Parent,
     Merger Sub and the Company containing certain representations of Parent,
     Merger Sub and the Company (the "Tax Representation Letters"); and

     (c)  such other instruments and documents related to the formation,
     organization and operation of Parent, Merger Sub and the Company and
     related to the completion of the Merger and the other transactions
     contemplated by the Reorganization Agreement as we have deemed necessary or
     appropriate.

In connection with rendering this opinion, we have assumed (without any
independent investigation or review thereof) that:

     (a)  Original documents submitted to us (including signatures thereto) are
     authentic, documents submitted to us as copies conform to the original
     documents, and that all such documents have been (or will be by the
     Effective Time) duly and validly executed and delivered where due execution
     and delivery are a prerequisite to the effectiveness thereof;

     (b) All representations, warranties and statements made or agreed to by
     Parent, Merger Sub and the Company, their respective management, employees,
     officers, directors and stockholders in connection with the Merger,
     including, but not limited to, those set forth in the Reorganization
     Agreement (including the exhibits thereto) and the Tax Representation
     Letters are true and accurate at all relevant times;

     (c) All covenants contained in the Reorganization Agreement (including
     exhibits thereto) and the Tax Representation Letters are performed without
     waiver or breach of any material provision thereof;

     (d) The Merger will be reported by Parent and the Company on their
     respective federal income tax returns in a manner consistent with the
     opinion set forth below;

     (e) Any representation or statement made "to the best of knowledge" or
     similarly qualified is correct without such qualification; and

     (f) The opinion dated February 8, 2000 rendered by Wilson Sonsini Goodrich
     & Rosati, P.C. to the Company with respect to the qualification of the
     Merger as a reorganization within the meaning of Section 368(a)(1) of the
     Code has been delivered and has not been withdrawn.

Based on our examination of the foregoing items and subject to the limitations,
qualifications, assumptions and caveats set forth herein, we are of the opinion
that, for federal income tax purposes, the Merger will be a reorganization
within the meaning of Section 368(a)(1) of the Code.
<PAGE>

In addition to your request for our opinion on this specific matter of federal
income tax law, you have asked us to review the discussion of federal income tax
issues contained in the Registration Statement. We have reviewed the discussion
entitled "Material Federal Income Tax Consequences" contained in the
Registration Statement and believe that, insofar as it relates to statements of
law and legal conclusions, is correct in all material respects.

This opinion does not address the various state, local or foreign tax
consequences that may result from the Merger or the other transactions
contemplated by the Reorganization Agreement. In addition, no opinion is
expressed as to any federal income tax consequence of the Merger or the other
transactions contemplated by the Reorganization Agreement except as specifically
set forth herein, and this opinion may not be relied upon except with respect to
the consequences specifically discussed herein. No opinion is expressed as to
the federal income tax treatment that may be relevant to a particular investor
in light of personal circumstances or to certain types of investors subject to
special treatment under the federal income tax laws (for example, life insurance
companies, dealers in securities, taxpayers subject to the alternative minimum
tax, banks, tax-exempt organizations, non-United States persons, and
stockholders who acquired their shares of Company capital stock pursuant to the
exercise of options or otherwise as compensation or who hold their Company
capital stock as part of a straddle or risk reduction transaction).

No opinion is expressed as to any transaction other than the Merger as described
in the Reorganization Agreement, or as to any transaction whatsoever, including
the Merger, if all of the transactions described in the Reorganization Agreement
are not consummated in accordance with the terms of the Reorganization Agreement
and without waiver of any material provision thereof. To the extent that any of
the representations, warranties, statements and assumptions material to our
opinion and upon which we have relied are not accurate and complete in all
material respects at all relevant times, our opinion would be adversely affected
and should not be relied upon.

This opinion only represents our best judgment as to the federal income tax
consequences of the Merger and is not binding on the Internal Revenue Service or
any court of law, tribunal, administrative agency or other governmental body.
The conclusions are based on the Code, existing judicial decisions,
administrative regulations and published rulings. No assurance can be given that
future legislative, judicial or administrative changes or interpretations would
not adversely affect the accuracy of the conclusions stated herein.
Nevertheless, by rendering this opinion, we undertake no responsibility to
advise you of any new developments in the application or interpretation of the
federal income tax laws.

This opinion is being delivered solely in connection with the filing of the
Registration Statement. It is intended for the benefit of Parent, Merger Sub and
the stockholders of the Company and may not be relied upon or utilized for any
other purpose or by any other person and may not be made available to any other
person without our prior written consent.

We consent to the reference to our firm under the caption "THE MERGER - Material
Federal Income Tax Consequences" in the Proxy Statement/Prospectus included in
the Registration Statement and to the reproduction and filing of this opinion as
an exhibit to the Registration Statement.

Sincerely,

COOLEY GODWARD LLP

                 [WISON SONSINI GOODRICH & ROSATI LETTERHEAD]


February 8, 2000



Etec Systems, Inc.
26460 Corporate Avenue
Hayward, CA 94545

Ladies and Gentlemen:

     This opinion is being delivered to you in connection with the Form S-4
Registration Statement (the "Registration Statement") filed pursuant to the
Agreement and Plan of Reorganization dated as of January 12, 2000 (the
"Reorganization Agreement"), among Applied Materials, Inc., a Delaware
corporation (Parent), Boston Acquisition Sub, Inc., a Nevada corporation and
wholly-owned subsidiary of Parent ("Merger Sub"), and Etec Systems, Inc., a
Nevada corporation (the "Company").  We have acted as counsel to the Company.
Pursuant to the Agreement, Merger Sub will merge with and into the Company (the
"Merger"), the separate corporate existence of Merger Sub will cease and the
Company will become a wholly-owned subsidiary of Parent.  You have requested our
opinion concerning certain United States federal income tax consequences of the
Merger.

     Unless otherwise defined, capitalized terms referred to herein have the
meanings set forth in the Agreement or in the Proxy Statement/Prospectus. All
section references, unless otherwise indicated, are to the Internal Revenue Code
of 1986, as amended (the "Code").

     In delivering our opinion, we have reviewed and relied upon (without any
independent investigation) the truth and accuracy, at all relevant times, of the
facts, statements, covenants, descriptions, representations, and warranties
contained in the following documents (including all exhibits and schedules
attached thereto):

     1.   The Agreement;

     2.   The Registration Statement;

     3.   Those certain tax representation letters delivered to us by Parent,
          Merger Sub and the Company containing certain representations of
          Parent, Merger Sub and the Company (the "Tax Representation Letters")
          and;

     4.   Such other instruments and documents related to the formation,
          organization, and operation of Parent, Merger Sub, and the Company and
          related to the Merger, as we have deemed necessary or appropriate.

     In connection with rendering this opinion, we also have assumed (without
any independent investigation) that:

     1.   Original documents (including signatures thereto) submitted to us are
          authentic, documents submitted to us as copies conform to the original
          documents, and that all such documents have been (or will be by the
          Effective Time) duly and validly executed and delivered where due
          execution and delivery are prerequisites to effectiveness thereof;

     2.   All representations, warranties, and statements made or agreed to by
          Parent, Merger Sub, the Company, their managements, employees,
          officers, directors, and shareholders in connection with the Merger,
          including, but not limited to, those set forth in the Agreement
          (including the exhibits thereto) and the Tax Representation Letters
          are true and accurate at all relevant times and no actions have been
          (or will be) taken which are inconsistent with such representations;

     3.   All covenants contained in the Agreement (including exhibits thereto)
          and the Tax Representation Letters are performed without waiver or
          breach of any material provision thereof;

     4.   The Merger will be reported by Parent and the Company on their
          respective federal income tax returns in a manner consistent with the
          opinion set forth below;
<PAGE>

     5.   Any representation or statement made in any of the documents referred
          to herein "to the knowledge" of any person or party or similarly
          qualified is correct without such qualification; and

     6.   The opinion dated February 8, 2000 rendered by Cooley Godward LLP to
          Parent with respect to the qualification of the Merger as a
          reorganization within the meaning of Section 368(a) of the Code has
          been delivered and has not been withdrawn.

     Based on our examination of the foregoing items and subject to the
assumptions, exceptions, limitations and qualifications set forth herein, we are
of the opinion that the Merger will qualify as a "reorganization" within the
meaning of Section 368(a) of the Code.

     In addition to your request for our opinion on this specific matter of
federal income tax law, you have asked us to review the discussion of federal
income tax issues contained in the Registration Statement. We have reviewed the
discussion entitled "Material Federal Income Tax Consequence" contained in the
Registration Statement and believe that, insofar as it relates to statements of
law and legal conclusions, is correct in all material respects.

     This opinion represents and is based upon our best judgment regarding the
application of United States federal income tax laws arising under the Code,
existing judicial decisions, administrative regulations and published rulings
and procedures.  Our opinion is not binding upon the Internal Revenue Service or
the courts, and there is no assurance that the Internal Revenue Service will not
successfully assert a contrary position.  Furthermore, no assurance can be given
that future legislative, judicial or administrative changes, on either a
prospective or retroactive basis, will not adversely affect the accuracy of the
conclusions stated herein.  Nevertheless, we undertake no responsibility to
advise you of any new developments in the application or interpretation of the
United States federal income tax laws.

     This opinion addresses only the matters stated herein, and does not address
any other federal, state, local or foreign tax consequences that may result from
the Merger or any other transaction (including any transaction undertaken in
connection with the Merger).

     No opinion is expressed as to any transaction other than the Merger as
described in the Agreement or to any transaction whatsoever, including the
Merger, if all the transactions described in the Agreement are not consummated
in accordance with the terms of such Agreement and without waiver or breach of
any material provision thereof or if all of the representations, warranties,
statements and assumptions upon which we relied are not true and accurate
through the Effective Time and at all relevant times thereafter. In the event
any one of the statements, representations, warranties or assumptions upon which
we have relied to issue this opinion is incorrect, our opinion might be
adversely affected and may not be relied upon.

     We hereby consent to the filing of this opinion with the Securities and
Exchange Commission as an exhibit to the Registration Statement at the time of
the filing thereof, and to the references made to us under the caption "THE
MERGER - Material Federal Income Tax Consequences" in the Proxy
Statement/Prospectus included in the Registration Statement. In giving such
consent, we do not thereby admit that we are in the category of persons whose
consent is required under Section 7 of the Act.

                               Very truly yours,
