Dear Stockholder:
 
     You are cordially invited to attend a special meeting of the stockholders
of Consilium on                , 199 at the principal executive offices of
Consilium located at 485 Clyde Avenue, Mountain View, California, at 10:00 A.M.
At the special meeting, you will be asked to vote on a proposal to approve the
merger agreement among Applied Materials, Consilium and a wholly owned
subsidiary of Applied Materials. As a result of the merger proposed in the
merger agreement, Consilium will become a wholly owned subsidiary of Applied
Materials and you will become a stockholder of Applied Materials.
 
     The merger will combine Applied Materials' global presence in semiconductor
wafer fabrication equipment with Consilium's expertise in the supply of
integrated semiconductor and electronics manufacturing execution systems and
services.
 
     Upon the closing of the merger, each holder of a share of Consilium common
stock will receive between 0.182 and 0.165 of a share of Applied Materials
common stock in exchange for one share of Consilium common stock. The actual
fraction of a share of Applied Materials common stock that will be issued to you
for each share of Consilium common stock that you own will be determined by
dividing $5.50 by the average of the closing sale price of a share of Applied
Materials common stock on the Nasdaq National Market for a specified period
before the Consilium special meeting. If the average price is $30.25 or less,
then the fraction will be 0.182. If the average price is $33.43 or more, then
the fraction will be 0.165. Applied Materials common stock is traded on the
Nasdaq National Market under the symbol "AMAT." Consilium Common Stock is traded
on the Nasdaq National Market under the symbol "CSIM."
 
     CONSILIUM'S BOARD OF DIRECTORS BELIEVES THAT THE MERGER IS FAIR TO YOU AND
IN YOUR BEST INTERESTS. THE BOARD HAS UNANIMOUSLY APPROVED THE MERGER AGREEMENT
AND THE MERGER AND RECOMMENDS THAT YOU VOTE TO APPROVE BOTH THE MERGER AGREEMENT
AND THE MERGER.
 
     Because of the significance of the merger, your participation in the
special meeting, in person or by proxy, is especially important. We hope you
will be able to attend the special meeting. However, even if you anticipate
attending in person, we urge you to mark, sign and return the enclosed proxy
card promptly in the enclosed postage-paid envelope to ensure that your shares
of common stock will be represented at the special meeting. If you do attend,
you will, of course, be able to vote your shares in person.
 
     Any Consilium stockholder who would like information regarding the exchange
ratio may call Consilium's proxy solicitor, MacKenzie Partners, Inc., at (800)
322-2885. MacKenzie Partners will provide to any requesting stockholder an
estimate of the exchange ratio as of any date prior to and including the date on
which the exchange ratio is finally determined. MacKenzie Partners will also
provide instructions on how to submit proxies in a timely manner, including
instructions for any stockholder who wishes to wait until the exchange ratio is
finally determined before voting. Any Consilium stockholder who wishes to change
their vote may do so by transmitting the request by facsimile to MacKenzie
Partners at (212) 929-0308.
 
     Thank you, and we look forward to seeing you at the special meeting.

                     QUESTIONS AND ANSWERS ABOUT THE MERGER
 
Q: WHY ARE THE TWO COMPANIES PROPOSING TO MERGE? HOW WILL I BENEFIT?
 
A: The Board of Directors of Applied Materials believes, among other things,
   that:
 
   - Consilium is established as a leader in providing semiconductor and
     electronics manufacturers a way to optimize manufacturing performance; and
 
   - the merger will further Applied Materials' continued commitment to
     customers to improve overall equipment effectiveness and total productivity
     and will serve Applied Materials' primary business objective of providing
     Total Solutions(TM) to Applied Materials' customers.
 
   The Board of Directors of Consilium believes, among other things, that:
 
   - the merger will provide an opportunity for Consilium, as part of the
     combined company, to compete more effectively in an increasingly
     competitive and rapidly changing industry;
 
   - the consideration you will receive in the merger is fair to you and in your
     best interests, especially in light of the fact that, at the time the
     parties signed the merger agreement, the market value of Applied Materials
     common stock to be issued in exchange for Consilium common stock
     represented a significant premium over the recent price range of Consilium
     common stock; and
 
   - the Applied Materials common stock you will receive in the merger has
     significantly greater liquidity than Consilium common stock.
 
Q: WHAT WILL I RECEIVE IN THE MERGER?
 
A: If the merger is completed, you will receive between 0.182 and 0.165 of a
   share of Applied Materials common stock for each share of Consilium common
   stock that you own. The actual fraction of a share of Applied Materials
   common stock that will be issued to you for each share of Consilium common
   stock you own will be determined by dividing $5.50 by the average of the
   closing sale price of a share of Applied Materials common stock on the Nasdaq
   National Market for the twenty trading days up to and including the second
   trading day before the Consilium special meeting.
 
     The table below shows, for a range of potential average Applied Materials
common stock prices, the fraction of a share of Applied Materials common stock
you will receive for each share of Consilium common stock and the implied value
of one share of Consilium common stock at those prices:

   $23.00           0.182             $4.19
    25.00           0.182              4.55
    27.00           0.182              4.91
    29.00           0.182              5.28
    30.25           0.182              5.51
    31.84           0.173              5.51
    33.43           0.165              5.52
    35.00           0.165              5.78
    37.00           0.165              6.11
    39.00           0.165              6.44
</TABLE>
 
     If the average price of Applied Materials common stock drops below $30.25,
you will still receive no more than 0.182 of a share of Applied Materials common
stock for each share of Consilium common stock you own; similarly, if the
average price of Applied Materials common stock exceeds $33.43, you will receive
no less than 0.165 of a share of Applied Materials common stock for each share
of Consilium common stock you own, except as provided below. The fact that the
maximum exchange ratio is 0.182 regardless of the market price of Applied
Materials common stock at closing means that there is no guarantee as to the
value of the consideration to be received by Consilium stockholders in the
merger.
 
     It is possible that, if Consilium issues shares of its stock or grants
stock options before the effective time of the merger such that the
"fully-diluted capitalization" of Consilium (i.e., the sum of the number of
shares of Consilium common stock outstanding immediately before the effective
time of the merger and the number of shares issuable upon exercise of stock
options and warrants outstanding immediately before the effective time of the
merger) is greater than 12,798,447, the exchange ratio will be adjusted to take
such new shares into
 
                                        2
<PAGE>   9
 
account. In that case, the exchange ratio could be lower than 0.165. As of
October 22, 1998, the "fully-diluted capitalization" of Consilium was
12,434,894.
 
     Applied Materials will not issue fractions of its shares to you in the
merger. Instead, you will receive cash for any fractional Applied Materials
shares owed to you upon the merger based on the market value of such shares on a
date close to the date of the Consilium special meeting.
 
     Example using October 12, 1998 as the Consilium special meeting date and
assuming the merger closed on that day:
 
     - the average closing price of Applied Materials common stock for the
       twenty trading days up to and including the second trading day before
       October 12, 1998 was $24.575.
 
     - the exchange ratio would have been 0.182 and would have implied a value
       of one share of Consilium common stock on that day of approximately
       $4.47.
 
     - if you owned 100 shares of Consilium common stock on that day, then after
       the merger you would have been entitled to receive 18 shares of Applied
       Materials common stock and cash in the amount of approximately $4.92.
 
Q: WHAT DO I NEED TO DO NOW?
 
A: After carefully reading and considering the information contained in this
   document, indicate on your proxy card how you want to vote, and sign and mail
   the proxy card in the enclosed return envelope as soon as possible, so that
   your shares may be represented at the Consilium special meeting. If you sign
   and send in your proxy card and do not indicate how you want to vote, we will
   count your proxy card as a vote in favor of the merger agreement and the
   merger. If you do not vote or you abstain, it will have the effect of a vote
   against the merger agreement and the merger.
 
     The Consilium special meeting will take place on                     ,
199  . You may attend the meeting and vote your shares in person, rather than by
signing and mailing your proxy card. In addition, you may revoke your proxy card
up to and including the day of your stockholders' meeting and vote in person.
 
     THE BOARD OF DIRECTORS OF CONSILIUM UNANIMOUSLY RECOMMENDS VOTING IN FAVOR
OF THE MERGER AGREEMENT AND THE MERGER.
 
Q: HOW CAN I DETERMINE THE ACTUAL EXCHANGE RATIO PRIOR TO VOTING?
 
A: You may call MacKenzie Partners at 1-800-322-2885 for an estimate of the
   exchange ratio as of a certain date prior to voting.
 
Q: HOW CAN I VOTE OR CHANGE MY PRIOR VOTE AFTER THE ACTUAL EXCHANGE RATIO IS
   DETERMINED?
 
A: You may transmit your initial vote or your request to change your vote by
   facsimile to MacKenzie Partners at (212) 929-0308.
 
Q: IF MY BROKER HOLDS MY SHARES IN "STREET NAME," WILL MY BROKER VOTE MY SHARES
   FOR ME?
 
A: Your broker will vote your shares only if you provide instructions on how to
   vote. You should instruct your broker to vote your shares according to the
   directions your broker provides. Without instructions, your broker will not
   vote your shares.
 
Q: SHOULD I SEND MY STOCK CERTIFICATES NOW?
 
A: No. After the merger is completed, Applied Materials will send you written
   instructions for exchanging your share certificates.
 
Q: WHEN DO YOU EXPECT TO COMPLETE THE MERGER?
 
A: We are working toward completing the merger as quickly as possible. In
   addition to stockholder approvals, we must also obtain regulatory approval.
   If all necessary approvals are obtained in a timely manner, we hope to
   complete the merger by the end of calendar year 1998.
 
Q: WHAT ARE THE TAX CONSEQUENCES OF THE MERGER TO ME?
 
A: In most cases, the exchange of shares by you should be tax-free to you for
   federal income tax purposes. However, you will have to report a taxable gain
   or loss if you receive cash for fractional shares. To review the tax
   consequences to you and to Consilium in more detail, see pages 37 through 39.

THE CONSILIUM SPECIAL MEETING (SEE PAGE 20)
 
     Consilium will hold a special stockholders meeting at its principal
executive offices located at 485 Clyde Avenue, Mountain View, California 94043,
at 10:00 A.M. on           , 199 . At the special meeting, the Consilium Board
of Directors will ask Consilium's stockholders to adopt the merger agreement and
approve the merger.
 
     The Consilium Board of Directors believes that the merger is fair to you
and in your best interests and unanimously recommends that you vote "for" the
proposal to approve the merger agreement and the merger.
 
RECORD DATE; VOTING POWER; VOTE REQUIRED (SEE PAGE 21)
 
     Consilium stockholders owning shares as of the close of business on October
12, 1998, the record date, may vote at the Consilium special meeting.
 
     On the record date, there were 8,749,973 shares of Consilium common stock
allowed to vote at the special meeting. Consilium stockholders will have one
vote at the special meeting for each share of Consilium common stock they owned
on the record date.
 
     A majority of the shares of Consilium common stock outstanding on the
record date must vote to adopt the merger agreement and approve the merger.
 
VOTING AGREEMENTS (SEE PAGE 36)
 
     The officers and directors and a significant stockholder of Consilium (who
in the aggregate
 
                                        5
<PAGE>   12
 
held approximately 40.97% of the issued and outstanding shares of Consilium
common stock on the record date) have agreed to vote for the approval of the
merger agreement and the merger.
 
THE MERGER (SEE PAGE 22)
 
     We attach the merger agreement as Appendix A to this document. We encourage
you to read the merger agreement. It is the legal document governing the merger.
 
WHAT YOU WILL RECEIVE IN THE MERGER (SEE PAGE 42)
 
     Upon closing of the merger, you will have the right to receive between
0.182 and 0.165 of a share of Applied Materials common stock in exchange for
each share of Consilium common stock you own. The actual fraction of a share of
Applied Materials common stock that will be issued to you for each share of
Consilium stock you own will be determined by dividing $5.50 by the average of
the closing sale price of a share of Applied Materials common stock on the
Nasdaq National Market for the twenty trading days up to and including the
second trading day before the Consilium special meeting. If the average price is
$30.25 or less, then the fraction will be 0.182 and if the average price is
$33.43 or more, then the fraction will be 0.165, except as provided below. See
"Risk Factors -- Risks Associated with Exchange Ratio."
 
     It is possible that, if Consilium issues shares of its stock or grants
stock options before the effective time of the merger such that the
"fully-diluted capitalization" of Consilium (i.e., the sum of the number of
shares of Consilium common stock outstanding immediately before the effective
time of the merger and the number of shares issuable upon exercise of stock
options and warrants outstanding immediately before the effective time of the
merger) is greater than 12,798,447, the exchange ratio will be adjusted to take
such new shares into account. In that case, the exchange ratio could be lower
than 0.165. As of October 22, 1998, the "fully-diluted capitalization" of
Consilium was 12,434,894.
 
OWNERSHIP OF APPLIED MATERIALS FOLLOWING THE MERGER (SEE PAGE 45)
 
     Following the merger, existing Consilium stockholders will own less than
one percent of the Applied Materials common stock outstanding (based upon the
number of shares of Applied Materials common stock outstanding on October 12,
1998).
 
TREATMENT OF CONSILIUM STOCK OPTIONS AND WARRANTS (SEE PAGE 43 AND 44)
 
     At the effective time of the merger, Applied Materials will assume all
outstanding Consilium stock options and certain warrants. Each option will be
exercisable for Applied Materials common stock on the same terms as the original
option, and certain warrants will be exercisable for Applied Materials common
stock on the same terms as the original warrants. Certain other warrants will be
exercised in accordance with their terms prior to the merger.
 
MARKETS AND MARKET PRICES (SEE PAGE 12)
 
     Applied Materials' common stock is traded on the Nasdaq National Market
under the symbol "AMAT." On October 12, 1998, the last trading day before the
announcement that Applied Materials and Consilium entered into the merger
agreement, the closing sale price of Applied Materials common stock was reported
at $26.813 per share. Following the merger, Applied Materials common stock will
continue to be traded on the Nasdaq National market under the symbol "AMAT." On
October 27, 1998, the closing sale price of Applied Materials common stock was
reported at $31.875.
 
     Consilium common stock is traded on the Nasdaq National Market under the
symbol "CSIM." On October 12, 1998, the closing sale price of Consilium common
stock was reported at $1.813 per share. Following the merger, Consilium common
stock will no longer be traded on the Nasdaq National Market or on any other
exchange. On October 27, 1998, the closing sale price of Consilium common stock
was reported at $4.50.
 
     The stock prices of both Applied Materials and Consilium can fluctuate
broadly even over short periods of time. It is impossible to predict the actual
price of Applied Materials or Consilium common stock prior to the effective time
of the merger or at any other time.
 
RISK FACTORS (SEE PAGE 14)
 
     The merger and an investment in securities of Applied Materials involve
certain risks and uncertainties, including risks relating to the integration of
Applied Materials and Consilium, risks relating to
 
                                        6
<PAGE>   13
 
the ability to achieve beneficial synergies, risks associated with the exchange
ratio, risks relating to the respective businesses of Applied Materials and
Consilium and other risks and uncertainties discussed under "Risk Factors" and
elsewhere in this Proxy Statement/Prospectus and in the documents incorporated
herein by reference. In addition, Applied Materials recently announced the
completion of a restructuring plan and other matters that will result in
significant one-time charges in its fourth fiscal quarter of 1998. See "Risk
Factors," beginning on page 14.
 
MATERIAL FEDERAL INCOME TAX CONSIDERATIONS (SEE PAGE 37)
 
     Consilium and Applied Materials must each receive an opinion from their
outside legal counsel that the merger will be a tax-free reorganization for
federal income tax purposes and that, as a general matter, Consilium
stockholders should not be subject to federal income tax as a result of the
exchange of Consilium stock in the merger, except if they receive cash for
fractional shares.
 
TAX MATTERS ARE COMPLICATED AND THE TAX CONSEQUENCES OF THE MERGER TO YOU WILL
DEPEND ON THE FACTS OF YOUR OWN SITUATION. YOU SHOULD CONSULT YOUR TAX ADVISORS
FOR A FULL UNDERSTANDING OF THE TAX CONSEQUENCES OF THE MERGER TO YOU.
 
The Board of Directors of Consilium believes, among other things, that:
 
     - the merger will provide the opportunity for Consilium, as part of the
       combined company, to compete more effectively in an increasingly
       competitive and rapidly changing industry;
 
     - the consideration that you will receive in the merger is fair to you and
       in your best interest, especially in light of the fact that, at the time
       the parties signed the merger agreement, the market value of Applied
       Materials common stock to be issued in exchange for Consilium common
       stock represented a significant premium over the recent price range of
       Consilium common stock; and
 
     - the Applied Materials common stock that you will receive in the merger
       has significantly greater liquidity than Consilium common stock.
REASONS FOR THE MERGER (SEE PAGE 25)
 
The Board of Directors of Applied Materials believes, among other things, that:
 
     - Consilium is established as a leader in providing semiconductor and
       electronics manufacturers a way to optimize manufacturing performance;
       and
 
     - the merger will further Applied Materials' continued commitment to
       customers to improve overall equipment effectiveness and total
       productivity and will serve Applied Materials' primary business objective
       of providing Total Solutions(TM) to Applied Materials' customers.
 
     These and other reasons for approving and recommending the merger, as well
as negative factors in considering the merger, are explained in greater detail
on pages 25 through 28 of this document.
 
FAIRNESS OPINION OF FINANCIAL ADVISOR (SEE PAGE 29)
 
     In deciding to approve the merger, the Consilium Board of Directors
considered the opinion of its financial advisor, Broadview International LLC, as
to the fairness of the exchange ratio to Consilium's stockholders from a
financial point of view. Broadview International LLC performed several analyses
in connection with delivering its opinion. These analyses included comparing the
valuation of publicly traded companies considered comparable to Consilium,
comparing premiums paid in comparable public seller transactions, calculating
the present value of the potential future price of Consilium Common Stock and an
exchange ratio analysis. Consilium has attached the opinion of Broadview
International LLC as Appendix B to this Proxy Statement/Prospectus. YOU SHOULD
READ BROADVIEW INTERNATIONAL LLC'S ENTIRE OPINION CAREFULLY.
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER (SEE PAGE 33)
 
     A number of directors and executive officers of Consilium have interests in
the merger as employees and/or directors that are different from, or in addition
to, your interests. If we complete the merger, Applied Materials will arrange
for the continuation of certain indemnification arrangements for directors and
officers of Consilium. In addition, certain directors and officers of Consilium
will re-
 
                                        7
<PAGE>   14
 
ceive certain benefits upon completion of the merger, including accelerated
vesting of certain stock options pursuant to existing contractual arrangements.
Some directors and officers will have the right to receive severance benefits if
terminated under certain circumstances within one year after the completion of
the merger. Jonathan Golovin plans to enter into a separate agreement with
Applied Materials relating to the terms of his employment following the merger.
See "Approval of the Merger and Related Transactions -- Interests of Certain
Persons in the Merger," page 33.
 
CONDITIONS TO THE MERGER (SEE PAGE 53)
 
We will complete the merger only if a number of conditions, including the
following, are satisfied or waived:
 
     - continued accuracy of each party's representations and warranties and
       fulfillment of each party's promises contained in the merger agreement;
 
     - adoption of the merger agreement and approval of the merger by Consilium
       stockholders holding at least a majority of Consilium shares allowed to

     - delivery by each Party's independent accountants of letters addressing
       the appropriateness of "pooling of interests" accounting treatment;
 
     - delivery by each Party's attorneys of opinions addressing certain federal
       income tax consequences of the merger;
 
     - no material adverse change having occurred to Consilium; and
 
     - expiration of the period within which the government should notify
       Consilium and Applied Materials of any antitrust issues concerning the
       merger.
 
TERMINATION OF THE MERGER AGREEMENT
(SEE PAGE 57)
 
Consilium and Applied Materials can agree to terminate the merger agreement at
any time without completing the merger. Additionally, Consilium or Applied
Materials may terminate the merger agreement under various circumstances,
including if:
 
     - the merger is not completed by March 31, 1999;
     - a court permanently prohibits the merger; or
 
     - the Consilium stockholders do not approve the merger agreement and the
       merger at the special meeting.
 
     Further, Consilium may terminate the merger agreement if Applied Materials'
representations and warranties were at the time the merger agreement was signed,
or become before the closing, inaccurate and cannot be corrected, and the result
is that a condition to Consilium's closing the merger cannot be satisfied.
Applied Materials may terminate the merger agreement if Consilium's
representations and warranties were at the time the merger agreement was signed,
or become before the closing, inaccurate and cannot be corrected, and the result
is that a condition to Applied Materials' closing the merger cannot be
satisfied. Applied Materials may also terminate the merger agreement if
Consilium's board of directors takes certain actions (such as withdrawing its
recommendation of the merger), or fails to take certain actions (such as failing
to reject another offer), in connection with the merger.
 
TERMINATION FEES (SEE PAGE 58)
 
     Under certain circumstances, including circumstances involving the
announcement by a third party (other than Applied Materials) of its desire to
acquire Consilium, the merger agreement may require Consilium to pay to Applied
Materials a termination fee of $1,000,000. If Consilium enters into an
acquisition or certain other business transactions with a third party (other
than Applied Materials) within 360 days after payment of the $1,000,000
termination fee referred to above, the merger agreement may require Consilium to
pay to Applied Materials an additional $1,000,000.
 
REGULATORY APPROVALS (SEE PAGE 40)
 
     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 Consilium have each filed the required notification and report
forms with the Federal Trade Commission and, the Antitrust Division, and are
preparing to file with the German anticompetition authority by early November.
Even if the required waiting periods expire, the Antitrust Division, Federal
Trade Com-
 
                                        8

mission 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 Consilium.
 
ACCOUNTING TREATMENT (SEE PAGE 39)
 
     We expect the merger to be accounted for as a pooling of interests, which
means that we will treat our companies as if they had always been combined for
accounting and financial reporting purposes.

(1) Applied Materials' fiscal year ends on the last Sunday in October of each
    year. The fiscal year ends for the periods presented are: October 31, 1993,
    October 30, 1994, October 29, 1995, October 27, 1996 and October 26, 1997.
 
(2) Fiscal 1996 includes a restructuring charge of $25,100. Fiscal 1997 includes
    bad debt expense of $16,318, acquired in-process research and development
    expense of $59,500 and pre-tax income from litigation settlements of
    $69,000. The nine months ended July 27, 1997 includes bad debt expense of
    $16,318, acquired in-process research and development expense of $59,500,
    and income from a litigation settlement of $80,000. The nine months ended
    July 26, 1998 includes a restructuring charge of $35,000, acquired
    in-process research and development expense of $32,227, and income from a
    litigation settlement of $80,000.
 
(3) The tax rate for fiscal 1997 and the nine months ended July 27, 1997 was
    higher than the expected rate of 35 percent due to the non-deductible nature
    of acquired in-process research and development expense of $59,500. The tax
    rate for the nine months ended July 26, 1998 is 34% due to several factors,
    including a shift in geographic composition of pre-tax income to entities
    operating in countries with lower tax rates and the enactment of favorable
    tax legislation in certain jurisdictions in which Applied Materials has
    significant operations.

     The estimated equivalent per share price of a share of Consilium common
stock represents 0.182 of the price of a share of Applied Materials common
stock. 0.182 is the fraction of a share of Applied Materials common stock that
you would have had the right to receive if the Consilium special meeting had
taken place on October 12, 1998, when the average closing price of Applied
Materials common stock for the twenty trading days up to and including the
second trading day before October 12, 1998, was $24.575. The actual fraction of
Applied Materials common stock that you will have the right to receive if the
merger closes may be different than this fraction because the average closing
price on the Nasdaq National Market for Applied Materials common stock
fluctuates continuously.

                                  RISK FACTORS
 
     This Proxy Statement/Prospectus contains forward-looking statements. These
statements relate to future events or the future financial performance of
Applied Materials and Consilium. In some cases, you can identify forward-looking
statements by terminology such as "may," "will," "should," "expects," "plans,"
"anticipates," "believes," "estimates," "predicts," "potential," or "continue"
or the negative of such terms and other comparable terminology. These statements
only reflect management's expectations and estimates and estimates. Actual
events or results may differ materially. In evaluating these statements, you
should specifically consider various factors, including the risks outlined
below. These factors may cause our actual results to differ materially from any
forward-looking statements. We are not undertaking any obligations to update any
forward-looking statements contained in this Proxy Statement/Prospectus to
reflect any future events or developments.
 
     The following factors should be considered carefully by the Consilium
stockholders in evaluating whether to adopt the merger agreement and approve the
merger. These factors should be considered in conjunction with any additional
risk factors in documents incorporated by reference in this Proxy
Statement/Prospectus and any other information included on incorporated by
reference herein, including in conjunction with forward-looking statements made
herein. See "Where You Can Find More Information" on page 1.
 
RISKS RELATING TO THE MERGER
 
UNCERTAINTY RELATING TO INTEGRATION
 
     After the merger, Applied Materials and Consilium, each of which previously
operated independently, will have to integrate their operations. The integration
will require significant efforts from each company, including the coordination
of their research and development and sales and marketing efforts. Applied
Materials may find it difficult to integrate the operations of Consilium.
Consilium personnel may leave Consilium because of the merger. Consilium
customers, distributors or suppliers may terminate their arrangements with
Consilium, or demand amended terms to these arrangements. Applied Materials
management may have their attention diverted while trying to integrate the two
companies. Such diversion of management's attention or difficulties in the
transition process could have an adverse impact on Applied Materials. If Applied
Materials is not able to successfully integrate the operations of Consilium,
Applied Materials' expectations for its future results of operations may not be
met.
 
FAILURE TO ACHIEVE BENEFICIAL SYNERGIES
 
     The managements of Applied Materials and Consilium have entered into the
merger agreement with the expectation that the merger will result in beneficial
synergies. Achieving these anticipated synergies and the potential benefits
underlying the two companies' reasons for the merger will depend on a number of
factors, some of which include:
 
          - Consilium's ability to timely develop new products and to ensure
            that the products it offers to its customers, as well as software,
            systems and products received from suppliers and used internally,
            are Year 2000 compliant;
 
          - The risk that Consilium's customers may defer purchasing decisions
            following the announcement of the merger;
 
          - The risk that it may be more difficult to retain Consilium's key
            management, marketing and technical personnel after the merger;
 
          - Potential severance payment liabilities and acceleration of stock
            options following certain officers' termination of employment with
            Consilium;
 
        - Potential contingent liabilities, including unasserted contingent
          liabilities arising from the divestiture of Consilium's FlowStream
          line of products;
 
                                       14
<PAGE>   21
 
        - The ability of the combined company to increase sales of Consilium
          products, especially in Asia; and
 
        - The ability of the combined company to increase sales of Applied
          Materials' products.
 
     Even if the two companies are able to integrate operations, there can be no
assurance that the anticipated synergies will be achieved. The failure to
achieve such synergies could have a material adverse effect on the business,
results of operations and financial condition of the combined company.
 
RISKS ASSOCIATED WITH EXCHANGE RATIO
 
     As a result of the merger, each outstanding share of Consilium common stock
will be converted into the right to receive between 0.182 and 0.165 of a share
of Applied Materials common stock. The exact fraction of a share of Applied
Materials common stock that will be issued to you for each share of Consilium
stock you own will be determined by dividing $5.50 by the average of the closing
sale price of a share of Applied Materials common stock on the Nasdaq National
Market for the twenty trading days up to and including the second trading day
before the Consilium special meeting. We cannot assure that the market price of
Applied Materials common stock upon and after the consummation of the merger
will not be lower or higher than the average closing price of such stock for the
twenty trading days up to and including the second trading day before the
Consilium special meeting. If the average price of Applied Materials common
stock drops below $30.25, you will still receive no more than 0.182 of a share
of Applied Materials common stock for each share of Consilium common stock you
own; similarly, if the average price of Applied Materials common stock exceeds
$33.43, you will receive no less than 0.165 of a share of Applied Materials
common stock for each share of Consilium common stock you own.
 
     It is possible that, if Consilium issues shares of its common stock or
options before the effective time of the merger such that the "fully-diluted
capitalization" of Consilium (i.e., the sum of the number of shares outstanding
immediately before the effective time of the merger and the number of shares
issuable upon exercise of stock options and warrants outstanding immediately
before the effective time of the merger) is greater than 12,798,447, the
exchange ratio may be lower than 0.165. As of October 22, 1998, the "fully-
diluted capitalization" of Consilium was 12,434,894. Because Consilium and
Applied Materials have agreed to the exchange ratio described above, the value
received by Consilium stockholders for each share of Consilium common stock will
depend on the average closing price of Applied Materials common stock at the
time immediately before completion of the merger. The following table shows
certain average prices for Applied Materials common stock and the implied value
paid by Applied Materials for each share of Consilium common stock upon
completion of the merger.

</TABLE>
 
     In recent years, and particularly in recent months, the stock market has
experienced extreme price and volume fluctuations. The broad market fluctuations
may adversely affect the market price of Applied Materials common stock. The
value of Applied Materials common stock at the time of the special meeting, the
date of completion of the merger, the date that Consilium stockholders receive
shares of Applied Materials common stock, the date that stockholders eventually
sell Applied Materials shares or at any other time, may
 
                                       15
<PAGE>   22
 
be significantly different than the price of Applied Materials common stock
today. The fact that the maximum exchange ratio is 0.182 regardless of the
market price of Applied Materials common stock at closing means that there is no
guarantee as to the value of the consideration to be received by Consilium
stockholders in the merger. See "Market Price Data and Dividends Policy" on page
12 for a table showing the recent volatility of the market price of Applied
Materials common stock. Consilium stockholders should obtain recent market
quotations for Applied Materials common stock and Consilium common stock and
understand the exchange ratio being offered in the merger.
 
RIGHTS OF HOLDERS OF CONSILIUM COMMON STOCK FOLLOWING THE MERGER
 
     Following the merger, holders of Consilium common stock outstanding on the
date of the merger's completion will become holders of Applied Materials common
stock. Certain differences exist between the rights of Consilium stockholders
under Consilium's Certificate of Incorporation, as amended, and Consilium's
bylaws and the rights of Applied Materials stockholders under Applied Materials'
Certificate of Incorporation, as amended, and Applied Materials' bylaws. See
"Comparison of Rights of Holders of Applied Materials Common Stock and Holders
of Consilium Common Stock."
 
RISKS RELATING TO APPLIED MATERIALS' BUSINESS
 
INDUSTRY VOLATILITY
 
     The semiconductor industry has historically been cyclical and subject to
sudden and sharp changes in supply and demand. The timing, length and severity
of these cycles are difficult to predict. During periods of reduced and
declining demand, Applied Materials must be able to quickly and effectively
align its cost structure with prevailing market conditions, and motivate and
retain key employees. During periods of rapid growth, Applied Materials must be
able to acquire and/or develop sufficient manufacturing capacity to meet
customer demand and hire and assimilate an adequate number of qualified people.
We cannot assure you that Applied Materials can align its costs structure
quickly, motivate or retain its key employees, acquire or develop sufficient
manufacturing capacity or assimilate enough qualified people.
 
     In response to the current industry downturn, Applied Materials has taken a
number of actions intended to align its cost structure with prevailing market
conditions. Most recently, on October 23, 1998, Applied Materials announced the
completion of a restructuring plan and certain non-recurring charges. Applied
Materials:
 
     - eliminated approximately 2,000 positions, or 15 percent of the company's
       global workforce in August 1998;
 
     - expects to incur charges of approximately $50 million for employee
       severance and benefits and an additional $50 million for consolidation of
       facilities and related fixed assets;
 
     - will record a $65 million reserve regarding a doubtful receivable
       obtained in connection with the settlement of patent litigation with ASM
       International N.V.;
 
     - will record, in its fourth fiscal quarter of 1998, an after-tax charge of
       approximately $50 million associated with the discontinuance of
       operations of its 50-50 joint venture, Applied Komatsu Technology, Inc.
       ("AKT"); and
 
     - will record a $70 million pre-tax write-down of intangible assets that
       are deemed to be impaired.
 
     As a result of non-recurring charges of $285 million associated with the
restructuring plan and other events, Applied Materials expects to incur a net
loss for its fourth fiscal quarter ending October 25, 1998. Also, during the
third fiscal quarter of 1998, Applied Materials completed a voluntary separation
plan and developed plans to consolidate certain facilities, which resulted in a
restructuring charge of $35 million for the third fiscal quarter of 1998.
Applied Materials has also significantly restricted new hiring and utilized
mandatory shutdown days in an effort to reduce costs. There can be no assurance
that Applied Materials will achieve the objectives of these cost reduction
programs.

<PAGE>   23
 
INDUSTRY OVERCAPACITY AND DEMAND SHIFTS IN THE PC INDUSTRY
 
     The semiconductor industry is currently characterized by excess production
capacity for the majority of device types, which has caused semiconductor
manufacturers to further decrease their capital spending. In the personal
computer market, a shift in demand from more expensive, high performance
products to lower-priced products (sub-$1,000 personal computers) has resulted
in reduced profitability for semiconductor manufacturers. As a result, customers
have delayed or decreased their purchases of Applied Materials' products.
Continued overcapacity and strengthening demand for sub-$1,000 personal
computers could cause further delays or decreased demand for Applied Materials'
products.
 
ASIAN ECONOMIES
 
     Asian countries, particularly Japan and Korea, continue to experience
banking, currency and other difficulties that are contributing to economic
slowdowns or recessions in those countries. The region does not appear to be
responding quickly to significant efforts to stimulate its economies. If Asian
economies remain stagnant or continue to deteriorate, capital investment by
Asian customers could decrease from current levels. With the onset of these
negative economic and industry conditions, customers in Japan and Korea have
canceled or delayed a significant amount of orders for Applied Materials'
products in fiscal 1998 and may cancel or delay additional orders in the future.
New orders and net sales to customers located in Asian countries for the third
fiscal quarter of 1998 were 44 percent and 40 percent, respectively, of Applied
Materials' totals.
 
GLOBAL BUSINESS
 
     Applied Materials sells systems and provides services to customers located
throughout the world. Managing global operations and sites located throughout
the world presents challenges associated with cultural diversities and
organizational alignment. Moreover, each region in the global semiconductor
equipment market exhibits unique characteristics that can cause capital
equipment investment patterns to vary significantly from period to period.
Although international markets provide Applied Materials with significant growth
opportunities, periodic economic downturns, trade balance issues, political
instability and fluctuations in interest and foreign currency exchange rates are
all risks that could affect global product and service demand.
 
APPLIED KOMATSU TECHNOLOGY, INC. JOINT VENTURE
 
     Applied Materials currently has a 50 percent ownership interest in AKT, a
joint venture corporation that develops thin film transistor manufacturing
systems for Active-Matrix Liquid Crystal Displays ("AMLCD"s). Applied Materials
announced that it will record, in its fourth fiscal quarter of 1998, an
approximate $50 million after-tax charge associated with the discontinuance of
operations of AKT. This charge will consist primarily of severance and benefit
costs related to job eliminations, facilities and asset write-offs and other
charges. However, Applied Materials cannot assure you that the actual costs of
discontinuing AKT's operations will not exceed $50 million.
 
BACKLOG
 
     Applied Materials' backlog was $1.0 billion as of July 26, 1998, compared
to $1.4 billion as of April 26, 1998 and $1.6 billion as of January 25, 1998.
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. Due to possible customer changes in delivery schedule and cancellation
of orders, Applied Materials' backlog at any particular date is not necessarily
indicative of actual sales for any succeeding period. A reduction of backlog
during any
 
                                       17
<PAGE>   24
 
particular period could have a material and adverse effect on Applied Materials'
business, financial condition and results of operations.
 
RISKS RELATED TO "YEAR 2000" COMPLIANCE
 
     Applied Materials has an initiative in place to address certain Year 2000
issues. Applied Materials has a formal Year 2000 Program Office focusing on four
key readiness areas: (1) Internal Infrastructure Readiness, addressing internal
hardware and software and non-information technology systems; (2) Supplier
Readiness, addressing the preparedness of those suppliers providing material
incorporated into Applied Materials' products; (3) Product Readiness, addressing
product functionality; and (4) Customer Readiness, addressing customer support
and transactional activity. For each readiness area, Applied Materials is
systematically performing a global risk assessment, conducting testing and
remediation (renovation and implementation), developing contingency plans to
mitigate unknown risk, and communicating with employees, suppliers, customers
and other third party business partners to raise awareness of the Year 2000
problem.
 
     - Internal Infrastructure Readiness Program. Applied Materials, assisted by
       a third party, has completed an inventory of internal applications and
       computer hardware and has commenced work on remediation strategies and
       testing. Some software applications have been made Year 2000 compliant,
       and resources have been assigned to address other applications based on
       their criticality and the time required to make them Year 2000 compliant.
       All software remediation is scheduled to be completed no later than July
       1999. The Year 2000 compliance evaluation of hardware, including hubs,
       routers, telecommunication equipment, workstations and other items, is
       nearing completion.
 
      In addition to applications and information technology hardware, Applied
      Materials is testing and developing remediation plans for embedded
      systems, facilities and other operations, such as financial and banking
      systems.
 
     - Supplier Readiness Program. This program focuses on minimizing the risks
       associated with suppliers in two areas: (a) a supplier's business
       capability to continue providing products and services; and (b) a
       supplier's product integrity. Applied Materials has identified and
       contacted key suppliers based on their relative risks in these two areas.
       To date, Applied Materials has received responses from the majority of
       its key suppliers, most of which indicate that the suppliers are in the
       process of developing remediation plans. Based on Applied Materials'
       assessment of each supplier's progress to adequately address the Year
       2000 issue, Applied Materials will develop a supplier action list and
       contingency plans. Supplier readiness issues that potentially affect
       Applied Materials' product retrofit program discussed below are targeted
       to be addressed by December 1998.
 
     - Product Readiness Program. This program focuses on identifying and
       resolving Year 2000 issues existing in Applied Materials' products. The
       program encompasses a number of activities including testing, evaluation,
       engineering, and manufacturing implementation. Applied Materials has
       adopted the Sematech Year 2000 Readiness Testing Scenarios as the
       baseline for product testing. Customers are being notified of known risk
       areas and proposed remediation plans. Applied Materials plans to make
       Year 2000 retrofits available to customers during the first calendar
       quarter of 1999, and to have retrofits installed in the field by June
       1999. A contingency team will be available after June 1999 to assist
       customers experiencing difficulties with Applied Materials' products.
 
     - Customer Readiness Program. This program focuses on customer support,
       including the coordination of retrofit activity, testing existing
       customer electronic transaction capability, and developing contingency
       plans where appropriate. Applied Materials is in the process of
       developing this program.
 
     Applied Materials estimates that total Year 2000 costs will range from $30
million to $50 million, the majority of which will be incurred during the next
five fiscal quarters. Applied Materials is continuing its assessments and
developing alternatives that will necessitate refinement of this estimate over
time. There can be no assurance, however, that there will not be a delay in, or
increased costs associated with, the programs described in this section.
 
                                       18
<PAGE>   25
 
     Since the programs described in this section are ongoing, Applied Materials
has not yet identified all potential Year 2000 complications nor completed all
remediation actions. Therefore, Applied Materials cannot determine the potential
impact of these complications and contingencies on Applied Materials' financial
condition and results of operations at this time. If computer systems used by
Applied Materials or its suppliers, or the software applications used in systems
manufactured and sold by Applied Materials (including applications used in
Consilium's products), fail or experience significant difficulties related to
the Year 2000, the failure or difficulties could materially and adversely affect
Applied Materials' results of operations and financial condition.
 
FOREIGN CURRENCY
 
     Significant operations of Applied Materials are conducted in foreign
currencies, primarily Japanese yen. Applied Materials actively manages its
exposure to changes in foreign currency exchange rates, but there can be no
assurance that future changes in foreign currency exchange rates will not have a
material and adverse effect on results of operations or financial condition.
 
EURO CONVERSION
 
     On January 1, 1999, eleven of the fifteen member countries of the European
Union are scheduled to establish fixed conversion rates between each of their
existing sovereign currencies and the Single European Currency (euro). The
participating countries have agreed to adopt the euro as their common legal
currency on that date.
 
     Applied Materials is currently evaluating issues raised by the introduction
of the euro as scheduled. Applied Materials expects that its relevant internal
systems will be euro capable by January 1, 1999, and does not expect the costs
of system modifications to be material. Applied Materials also expects that the
introduction and use of the euro will not materially and adversely affect
Applied Materials' results of operations.
 
     Applied Materials will continue to evaluate the impact of the euro
introduction. However, there can be no assurance that Applied Materials' systems
will be euro capable by January 1, 1999, or that costs to comply will not be
material.
 
HIGHLY COMPETITIVE INDUSTRY AND RAPID TECHNOLOGICAL CHANGE
 
     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 develop new products and:
 
     - develop new markets in the semiconductor industry for its products and
       services.
 
     - introduce new products to the marketplace on a timely basis;
 
     - qualify new products with its customers; and
 
     - commence production to meet customer demands.
 
     New products include those for production of 300mm technology and 0.25
micron and below devices. The introduction of new technology and products grows
increasingly complex over time. If Applied Materials does not develop and
introduce new products in a timely manner in response to changing market
conditions or customer requirements, its results of operations could be
materially and adversely affected. During the fourth fiscal quarter of 1998,
Applied Materials announced that it will record a $70 million pre-tax write-down
of intangible assets related to certain purchased technology. This write-off is
due to reduced demand resulting from significant changes in business conditions
and rapid changes in technology, which in combination have decreased the
realizable value of this technology.

RISKS ASSOCIATED WITH LITIGATION
 
     Applied Materials and certain of its subsidiaries are currently involved in
litigation regarding patent infringement, intellectual property rights,
antitrust and other matters and could become involved in additional litigation
in the future. Applied Materials from time to time receives and makes inquiries
with regard to possible patent infringement, and is subject to various other
legal proceedings and claims, either asserted or unasserted. Any such 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 litigation or patent infringement
inquiries.
 
RISKS RELATING TO CONSILIUM'S BUSINESS
 
     Consilium's business is subject to numerous risks, including risks related
to:
 
     - Consilium's past operating losses;
 
     - Consilium's dependence on the semiconductor industry and that industry's
       current downturn and volatility;
 
     - Consilium's dependence on its single "WorkStream" line of products;
 
     - Consilium's dependence on key vendors for the development of its systems
       integration services business and management of systems integration
       projects;
 
     - Consilium's dependence on international sales;
 
     - Consilium's history of financial covenant breaches with respect to its
       bank credit facilities;
 
     - the rapid technological changes characteristic of the industry and the
       need for new product development on a timely basis;
 
     - product defects associated with any new products;
 
     - Consilium's dependence on its key personnel;
 
     - failure to integrate or reap the benefits of its acquisitions;
 
     - competition in the industry;
 
     - concentration of Consilium's product revenues in a small number of
       customers;
 
     - the high average selling price of Consilium's products and the lengthy
       sales cycle;
 
     - quarterly fluctuations in operating results;
 
     - challenges to Consilium's proprietary rights; and
 
     A full discussion of these risks and other risks associated with
Consilium's business may be found in Consilium's Registration Statement on Form
S-1 (No. 333-44743), Annual Report on Form 10-K for the year ended October 31,
1997 and Consilium's Quarterly Reports on Form 10-Q for the quarterly periods
ended January 31, 1998, April 30, 1998 and July 31, 1998.

PURPOSE OF THE CONSILIUM SPECIAL MEETING
 
     The purpose of the Consilium special meeting is to vote upon a proposal to
adopt and approve the Agreement and Plan of Merger and Reorganization dated as
of October 12, 1998 among Consilium, Applied Materials and a wholly owned
subsidiary of Applied Material ("Merger Sub"), and to approve the merger of
Merger Sub with and into Consilium.
 
RECORD DATE AND OUTSTANDING SHARES
 
     The close of business on October 12, 1998 has been fixed by the Consilium
Board of Directors as the record date (the "Record Date") for determination of
the stockholders of Consilium entitled to notice of, and to vote at, the
Consilium special meeting or any postponement or adjournment of the Consilium
special meeting. Holders of record of the Consilium common stock at the close of
business on the Record Date are entitled to notice of, and to vote at, the
Consilium special meeting. As of the Record Date, there were approximately 212
stockholders of record holding an aggregate of approximately 8,749,973 shares of
Consilium common stock. See "Consilium Principal Stockholders." Except for the
stockholders identified herein under "Consilium Principal Stockholders," as of
the Record Date, to the knowledge of Consilium, no other person beneficially
owned more than 5% of the outstanding Consilium common stock.
 
     This Proxy Statement/Prospectus was mailed to all Consilium stockholders of
record as of the Record Date and constitutes notice of the Consilium special
meeting in conformity with the requirements of the Delaware General Corporation
Law ("DGCL").
 
VOTING OF PROXIES
 
     All properly executed proxies that are not revoked will be voted at the
Consilium special meeting in accordance with the instructions contained therein.
If a stockholder signs and returns a proxy without indicating any voting
instructions, the shares of Consilium common stock that the proxy represents
will be voted FOR the proposal to adopt and approve the merger agreement and FOR
approval of the merger under the recommendation of the Consilium Board of
Directors or FOR adjournment or postponement of the Consilium special meeting if
an adjournment or postponement, in the discretion of the proxy holders, is
determined to be necessary or desirable. A stockholder who has executed and
returned a proxy may revoke it at any time before it is voted at the Consilium
special meeting by (i) executing and returning a proxy bearing a later date,
(ii) filing written notice of such revocation with the Corporate Secretary of
Consilium stating that the proxy is being revoked, or (iii) attending the
Consilium special meeting and voting in person. All written notices of
revocation and other communications with respect to revocation of Consilium
proxies should be sent to: Consilium, Inc., 485 Clyde Avenue, Mountain View, CA
94043, Attention: Corporate Secretary. Attendance at the Consilium special
meeting, in and of itself, will not constitute a revocation of a proxy. See
"Questions and Answers About the Merger -- How Can I Vote or Change My Prior
Vote After the Actual Exchange Ratio is Determined".
 
VOTE REQUIRED
 
     Adoption and approval of the merger agreement and approval of the merger
require the affirmative vote of holders of a majority of the shares of Consilium
common stock outstanding as of the Record Date. Each stockholder of record of
Consilium common stock on the Record Date is entitled to cast one vote per
share, exercisable in person or by properly executed proxy, on each matter
properly submitted for the vote of the stockholders of Consilium at the
Consilium special meeting.
 
     Centennial Associates, L.P. and all of Consilium's directors and executive
officers, who own in the aggregate issued and outstanding shares of Consilium
common stock representing approximately 40.97% of the shares of Consilium common
stock issued and outstanding as of the Record Date, have entered into certain
voting agreements dated October 12, 1998 with Applied Materials (the "Voting
Agreements"), pursuant to which they have agreed that, prior to the earlier of
the effective time of the merger or the termination of the merger agreement,
they will vote their shares of Consilium common stock in favor of the merger,
the adoption and approval of the terms of the merger agreement, and each of the
other actions
 
                                       21
<PAGE>   28
 
contemplated by the merger agreement. See "Approval of the Merger and Related
Transactions -- Voting Agreements."
 
QUORUM; ABSTENTIONS
 
     The presence, in person or by properly executed proxy, of the holders of a
majority of the outstanding shares of Consilium common stock entitled to vote at
the Consilium special meeting is necessary to constitute a quorum. Abstentions
will be counted for purposes of determining a quorum, but will have the effect
of a vote against approval of the matters being voted upon. If a broker holding
shares in street name returns an executed proxy that indicates that the broker
does not have discretionary authority as to certain shares to vote on one or
more matters, such shares will be considered represented at the Consilium
special meeting for purposes of determining a quorum, but have the effect of a
vote against approval of the matters being voted upon.
 
SOLICITATION OF PROXIES; EXPENSES
 
     Regardless of whether Applied Materials and Consilium consummate the
merger, each of Consilium 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 Consilium and Applied
Materials will share equally fees and expenses (other than attorneys' and
accounting fees) incurred in connection with the printing, filing and mailing of
this Proxy Statement/Prospectus and the filing of the premerger notification and
report forms relating to the merger under Hart-Scott-Rodino Antitrust
Improvements Act of 1976 and the rules promulgated thereunder (the "HSR Act").
 
     Subject to the foregoing, Consilium will bear the cost of the solicitation
of proxies and all related costs. In addition, Consilium may reimburse brokerage
firms and other persons representing beneficial owners of shares for their
expenses in forwarding solicitation materials to such beneficial owners. Certain
directors, officers or other employees of Consilium may supplement original
solicitation of proxies by mail with telephone, facsimile or personal
solicitation, without payment of additional compensation.
 
                APPROVAL OF THE MERGER AND RELATED TRANSACTIONS
 
BACKGROUND OF THE MERGER
 
     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 Consilium. Set forth below is a summary of the background
of these negotiations.
 
     Applied Materials believes that MES shows significant growth potential, as
well as strategic synergy with Applied Materials' goal of providing technology
that improves customers' productivity and operations. The Board of Directors of
Applied Materials believes that Consilium, as a leading independent supplier of
MES software and services, provides comprehensive automated factory control
solutions for today's integrated circuit and electronics manufacturing
organizations and is developing new products for fabs of the future, including
300mm fabs. Applied Materials' Board of Directors expects that Applied Materials
with its global infrastructure, especially in Asia, could help Consilium further
penetrate its available markets.
 
     On July 21, 1998, Kalman Kaufman, Vice President of Applied Materials'
Strategic Development and Planning Group, called James Macek, Consilium's then
Executive Vice President, to invite Mr. Macek to Applied Materials' offices to
discuss generally the possibility of a business relationship between Applied
Materials and Consilium.
 
     On July 23, 1998, after conferring with Jonathan Golovin, Chairman of the
Board and Chief Technical Officer of Consilium, Mr. Macek met with Applied
Materials' representatives, i.e. Mr. Kaufman, James C. Morgan, Chairman of the
Board and Chief Executive Officer, Dan Maydan, President, Sasson Somekh, Senior
Vice President and Ash Munshi, then Vice President, Factory Automation, at the
offices of Applied Materials. At the meeting, the possibility of a business
relationship between the two companies was discussed.
 
                                       22
<PAGE>   29
 
     After the July 23, 1998 meeting, Mr. Kaufman, invited Laurence Hootnick,
President and Chief Executive Officer of Consilium and Michael J. Field, Senior
Vice President, Chief Administrative Officer and Corporate Secretary of
Consilium, to breakfast on July 27, 1998.
 
     At breakfast on July 27, 1998, with Messrs. Kaufman and Alexander Meyer,
Applied Materials Senior Director of New Business Development, Mr. Hootnick
raised the possibility of a minority equity investment by Applied Materials in
Consilium. Mr. Hootnick also suggested a discussion about an option for Applied
Materials to purchase all of the outstanding capital stock of Consilium.
Consequently, at the breakfast meeting, the parties decided that Applied
Materials and Consilium should enter into a nondisclosure agreement. That
afternoon, the companies entered into a nondisclosure agreement and agreed that
more detailed discussions and a more detailed level of exploration of
Consilium's business by Applied Materials could commence.
 
     On the evening of July 27, 1998, Messrs. Kaufman, Meyer, Hootnick and Field
met for dinner. They were joined at dinner by Dr. Somekh. At dinner the parties
discussed their respective businesses and the semiconductor industry generally.
Mr. Hootnick again raised the issue of a minority investment by Applied
Materials in Consilium, as well as the possibility of Applied Materials
receiving an option to purchase all of the outstanding capital stock of
Consilium. In addition, the parties discussed the possibility of Applied
Materials acquiring all of the outstanding capital stock of Consilium. The
parties began for the first time to discuss a possible price for such a
transaction, and whether any purchase price would be paid in cash or in Applied
Materials common stock. Mr. Hootnick noted to the representatives of Applied
Materials that Consilium would be more interested in a stock for stock
transaction that would be tax-free to Consilium stockholders.
 
     On July 29, 1998, Messrs. Meyer and Kaufman met with Messrs. Hootnick and
Field at the offices of Applied Materials for the purpose of discussing the
possibility that Applied Materials would acquire all of the outstanding capital
stock of Consilium. At the meeting, Mr. Kaufman proposed that Applied Materials
purchase each outstanding share of Consilium capital stock for a price of
between $3.50 and $4.00 per share, to be paid in shares of Applied Materials
common stock. Messrs. Hootnick and Field objected to this proposal, noting that
Consilium's stock price was undervalued in the marketplace, and advised that
they would not recommend the proposal to the Consilium Board of Directors.
 
     On August 3, 1998, Mr. Kaufman called Mr. Hootnick to suggest a further
meeting. On August 4, 1998, certain executives of both companies met and
continued a discussion about price and the expected development of Consilium's
business. After extensive discussions, the parties concluded that an acquisition
of Consilium by Applied Materials might be possible at a higher price. At this
time, Applied Materials asked its outside legal counsel, Cooley Godward LLP, to
prepare a due diligence request list.
 
     On August 6, 1998, as part of a special meeting of the Consilium Board of
Directors, Mr. Hootnick briefed the Board on the discussions between management
representatives of Applied Materials and Consilium. Outside counsel reviewed the
Board's fiduciary duties in considering a strategic business combination.
Consilium management discussed possible risks and benefits from a proposed
business combination between Consilium and Applied Materials and reviewed
questions and comments from the Board concerning such a combination. Management
also outlined Consilium's strategy and direction as an independent company, and
the Board discussed other alternatives. After consideration of these
discussions, the Consilium Board of Directors authorized management to continue
discussions with Applied Materials.
 
     For the remainder of August, Applied Materials and Consilium continued to
discuss both price and non-price terms of a possible acquisition of Consilium by
Applied Materials and Applied Materials continued its investigation of
Consilium's business, primarily through review of, publicly available
information and discussions with senior management of Consilium. On August 24,
1998, as part of a special meeting of the Consilium Board of Directors, Mr.
Hootnick briefed the Board on further discussions between Consilium and Applied
Materials management regarding price and other terms of the proposed business
combination, and management reviewed with the Board possible benefits and risks
of such a combination. After considering these discussions, the Consilium Board
of Directors concluded that management should pursue the discussions with
Applied Materials. In late August 1998, Consilium requested that Applied
Materials sign a
 
                                       23
<PAGE>   30
 
more comprehensive nondisclosure agreement than the nondisclosure agreement
previously signed on July 27, 1998 as a condition to conducting more extensive
due diligence, and directed its outside legal counsel, Gray Cary Ware &
Freidenrich LLP, to prepare such an agreement.
 
     On September 2, 1998, Mr. Kaufman made a presentation on the possible
acquisition to the Acquisition Subcommittee of the Applied Materials Board of
Directors.
 
     On September 3, 1998, at a special meeting of the Consilium Board of
Directors, Consilium management and outside legal counsel briefed the Consilium
Board of Directors on the terms of the proposed standstill and "no-shop"
agreements. Management and outside legal counsel reviewed with the Board the
negotiations on price and non-price terms, and responded to questions and
comments from the Board. The Board discussed the possible risks and benefits of
the proposed business combination in light of other alternatives available to
Consilium, concluded that discussions with Applied Materials should continue and
authorized Consilium management to enter into the "no-shop" agreement and
standstill agreement, subject to satisfactory conclusion of pending
negotiations.
 
     On September 4, 1998, Dr. Somekh and Mr. Kaufman made a presentation on the
possible acquisition to the full Board of Directors, discussing, among other
things, Consilium's market leadership position in the field of MES software, the
strategic rationale and preliminary terms contemplated for the proposed
transaction and potential benefits and risks of an acquisition. Following the
presentation, the Board directed the Acquisition Subcommittee to track the
progress of the ongoing negotiations and make sure the due diligence was
completed.
 
     During early September 1998, Applied Materials and Consilium negotiated the
terms of a Mutual Nondisclosure and Standstill Agreement and a "no-shop"
agreement. The "no-shop" agreement provided, among other things, that for a
period of fourteen days beginning on the date of the first "all hands" due
diligence meeting involving representatives of Applied Materials and Consilium,
Consilium would not solicit, engage in discussions or negotiations with, or
provide information to, a third party (other than Applied Materials) regarding a
possible acquisition of Consilium.
 
     On September 11, 1998, at a special meeting of the Consilium Board of
Directors, management reported to the Consilium Board on negotiations between
the parties concerning the terms of the transaction. Management and outside
counsel reviewed the effect of such terms and responded to questions and
comments from the Consilium Board of Directors.
 
     Applied Materials and Consilium signed the Mutual Nondisclosure and
Standstill Agreement and the "no-shop" agreement on September 17, 1998. On
September 23, 1998, representatives of Applied Materials and Consilium attended
an "all hands" due diligence meeting at which representatives of Consilium
discussed Consilium's business, current and proposed products, financial
condition and results of operations.
 
     On September 24, 1998, Consilium engaged Broadview International LLC as its
financial advisor to advise on the fairness of the exchange ratio to Consilium's
stockholders from a financial point of view.
 
     In late September 1998, Applied Materials requested access to certain
technical information (including source code) relating to Consilium's products.
Between September 21, 1998 and September 25, 1998, Applied Materials and
Consilium negotiated the terms of a nondisclosure agreement covering the
disclosure of certain sensitive technical information to a limited number of
representatives of Applied Materials. The parties signed that nondisclosure
agreement on September 25, 1998.
 
     Also in late September 1998, Cooley Godward LLP transmitted a draft merger
agreement and certain related draft agreements to Gray Cary Ware & Freidenrich
LLP. Between September 25, 1998 and October 12, 1998, Applied Materials and
Consilium and their outside legal counsel negotiated the terms of the merger
agreement and related agreements. In addition, during that period, Applied
Materials and its representatives continued their due diligence investigation of
Consilium. On October 5, 1998, at a special meeting of the Consilium Board of
Directors, representatives of management, Gray Cary Ware & Freidenrich LLP and
Broadview International reviewed with the Board the proposed terms of the draft
merger agreement and related agreements, including the conditions to the merger
and the timing and payment of fees in
 
                                       24
<PAGE>   31
 
connection with termination, and responded to questions and comments from the
Board. On October 7, 1998, Consilium extended the term of the "no-shop"
agreement from October 7, 1998 to the close of business on October 12, 1998.
 
     On October 8, 1998, at a special meeting of the Consilium Board of
Directors, management and Gray Cary Ware & Freidenrich LLP reviewed the
principal terms of the draft merger agreement and related agreements, as
revised, as well as the resolution of certain outstanding issues and reviewed
the strategic rationale for the merger, potential benefits and risks of the
proposed transaction, and alternatives available to Consilium. Representatives
of Broadview International reviewed with the Consilium Board of Directors their
financial analyses related to the proposed business combination.
 
     On October 12, 1998, at a special meeting of the Consilium Board of
Directors, management and Gray Cary Ware and Freidenrich LLP reported on the
revised terms of the merger agreement and related agreements. Representatives of
Broadview International reviewed their financial analyses with respect to the
proposed merger and delivered an oral opinion (subsequently confirmed in
writing) that the exchange ratio was fair to Consilium stockholders from a
financial point of view. After consideration of these presentations, the
Consilium Board of Directors unanimously approved the merger agreement and the
merger, concluding that the merger was fair, to and in the best interests of,
the Consilium stockholders.
 
     Also on October 12, 1998, the Board of Directors of Applied Materials,
together with their legal counsel, financial advisors and independent
accountants, held a special meeting to review the status of the transaction and
the terms of the merger agreement and the merger. At the Applied Materials
meeting, Applied Materials' legal counsel, financial advisors and management
reviewed the merger agreement and the resolution of previously outstanding
issues. The Acquisition Subcommittee reported that it had reviewed all aspects
of the proposed acquisition and unanimously recommended approval to the Board.
After discussion of the merger agreement and the merger with management and
their financial advisors and legal counsel, the Applied Materials Board of
Directors approved the merger.
 
     The definitive merger agreement and certain related agreements, including
the Voting Agreements and the Affiliate Agreements were executed on October 12,
1998.
 
REASONS FOR 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 Consilium with respect to future events that may have an effect
on their future financial performance. These forward-looking statements include
statements regarding the markets for Applied Materials', Consilium's and the
combined company's products and services, their planned response to the demands
of their markets, their product and sales strategies, and certain potential
technological and operating synergies intended to be achieved by the merger.
These forward-looking statements are subject to various risks and uncertainties
that could cause actual results of Applied Materials, Consilium and the combined
company to differ materially from those currently anticipated, including the
ability of Applied Materials and Consilium to successfully integrate their
operations and achieve expected synergies; the risk that customers may defer
purchasing decisions following the announcement of the merger; the ability of
Consilium to retain key employees following announcement of the merger; changes
in business conditions and growth trends affecting Applied Materials' and
Consilium's products and markets, the semiconductor and electronics industry and
the economy in general; technological advancements and new product offerings by
Applied Materials' and Consilium's competitors; Applied Materials' and
Consilium's ability to successfully introduce new products and upgrades to
existing products; and a variety of other competitive factors such as price
reductions by Applied Materials, Consilium or their competitors. These and other
factors that could cause actual results to differ materially are described under
"Risk Factors" and elsewhere in this Proxy Statement/Prospectus.
 
CONSILIUM'S REASONS FOR THE MERGER
 
     The Consilium Board of Directors believes that increasing competition and
industry consolidation is making it more difficult for Consilium to grow its
business as a relatively small independent company
 
                                       25
<PAGE>   32
 
competing with larger companies with substantially greater resources and
broader, integrated product offerings. Consilium's management has considered the
alternatives of either acquiring smaller companies that could extend its product
and service offerings and enhance the distribution of its products and services,
or merging with a larger company. In this industry environment, the Consilium
Board of Directors identified several potential benefits for the Consilium
stockholders and customers that it believes would result from the merger. These
potential benefits include:
 
     - the financial strength of Applied Materials could enable the combined
       company to commit greater resources to both current and emerging product
       development efforts and to fund the future growth of the combined
       company's business;
 
     - the ability to leverage Applied Materials' customer base and sales force
       to increase sales of Consilium's products and services;
 
     - the opportunity for Consilium, as part of the combined company, to
       compete more effectively in an increasingly competitive and rapidly
       changing industry; and
 
     - the greater liquidity and diversification of risk offered to Consilium
       stockholders by an investment in Applied Materials instead of Consilium.
 
     In the course of its deliberations, the Consilium Board of Directors
reviewed with Consilium's management a number of additional factors relevant to
the merger, including, among others:
 
     - information concerning Applied Materials' and Consilium's respective
       businesses, prospects, financial performance and condition, operations,
       technology, product and service lines, management and competitive
       position;
 
     - current market conditions and historical market prices, volatility and
       trading information with respect to Applied Materials common stock and
       Consilium common stock;
 
     - the consideration that Consilium stockholders will receive in the merger
       and the fact that, at the time the parties signed the merger agreement,
       the market value of the Applied Materials common stock to be issued in
       exchange for the Consilium common stock represented a significant premium
       over the recent price range of the Consilium common stock;
 
     - the significantly greater liquidity of Applied Materials common stock as
       compared with Consilium common stock;
 
     - current industry and economic conditions, including the current slowdown
       and volatility in the semiconductor industry;
 
     - the implications for continued independent operation of Consilium in
       light of market and competitive conditions, including the potential for
       increased competition from Applied Materials or another company having
       significantly greater financial resources than Consilium that is seeking
       to enter the MES market;
 
     - Consilium's long-term and short-term capital needs to develop and improve
       the FAB300(TM) product, especially in light of Consilium's competitive
       and market position as described above;
 
     - Applied Materials' leadership position as a supplier in the semiconductor
       industry and the increased potential for successful marketing of
       Consilium's FAB300(TM) product as a part of the product portfolio of a
       large, established equipment manufacturer;
 
     - the complementary products and services, channels, partners, technology
       and critical skills of Applied Materials and Consilium;
 
     - the alternatives available to Consilium in light of the consideration
       proposed to be paid to stockholders pursuant to the merger agreement,
       including continuing to maintain Consilium as an independent company and
       not engaging in any extraordinary transaction;
 
                                       26
<PAGE>   33
 
     - the belief that the terms of the merger agreement are reasonable,
       including the provisions allowing Consilium to respond to certain
       unsolicited inquiries concerning an acquisition of Consilium, and the
       provisions that permit the Company to terminate the merger agreement upon
       payment to Applied Materials of a break-up fee under certain
       circumstances;
 
     - a comparison of selected recent acquisition and merger transactions in
       the industry;
 
     - the view of the Consilium Board of Directors, based in part upon the
       presentations of management and Broadview International LLC, regarding
       the likelihood of a superior offer arising;
 
     - the expected tax and accounting treatment of the merger;
 
     - the opinion of Broadview International LLC rendered at the October 12,
       1998 meeting of the Consilium Board of Directors that, based upon and
       subject to the various assumptions and conditions set forth in the
       opinion, the exchange ratio was fair to holders of Consilium common stock
       from a financial point of view as of October 12, 1998;
 
     - the impact of the merger on Consilium's customers and employees; and
 
     - reports from management, financial advisors and legal advisors as to the
       results of their due diligence investigation of Applied Materials.
 
     The Consilium Board of Directors also considered a number of potentially
negative factors in its deliberations concerning the merger, including, but not
limited to:
 
     - the risk that the benefits sought to be achieved in the merger will not
       be achieved;
 
     - the fact that the maximum exchange ratio is 0.182 and that there is no
       guarantee as to the market value of the fraction of a share of Applied
       Materials common stock to be received for each share of Consilium common
       stock or that such market value will represent at closing a premium over
       the price range of Consilium common stock prior to the announcement of
       the merger agreement;
 
     - the loss of control over the future operations of Consilium following the
       merger;
 
     - the effect of the public announcement of the merger on Consilium's sales,
       customer relations and operating results and Consilium's ability to
       attract and retain key management, marketing and technical personnel;
 
     - the risk of market confusion and potential delay or reduction in orders
       for products and services; and
 
     - the other risks described above under "Risk Factors."
 
     The Consilium Board of Directors believed that certain of these risks were
unlikely to occur or unlikely to have a material impact on the combined company,
while others could be avoided or mitigated by Consilium or Applied Materials,
and that, overall, the risks associated with the merger were outweighed by the
potential benefits of the merger.
 
     The foregoing discussion of information and factors considered by the
Consilium Board of Directors is not intended to be all-inclusive but is believed
to include all material factors considered by the Consilium Board of Directors.
In view of the wide variety of factors considered by the Consilium Board of
Directors, the Consilium Board of Directors did not find it practicable to
quantify or otherwise assign relative weight to the specific factors considered.
However, after taking into account all of the factors set forth above, the
Consilium Board of Directors unanimously agreed that the merger agreement and
the consummation of the merger were fair to, and in the best interests of,
Consilium and its stockholders and that Consilium should proceed with the
merger.
 
APPLIED MATERIALS' REASONS FOR THE MERGER
 
     The Applied Materials Board of Directors has determined that the terms of
the merger agreement and the merger are fair to, and in the best interests of,
Applied Materials and its stockholders. In reaching its determination, the
Applied Materials Board of Directors consulted with Applied Materials'
management, as
 
                                       27
<PAGE>   34
 
well as its legal counsel, financial advisors and independent accountants, and
gave significant consideration to a number of factors bearing on its decision.
The following are among the reasons the Applied Materials Board of Directors
believes the merger will be beneficial to Applied Materials and its
stockholders:
 
     - Applied Materials seeks to grow both internally and through the
       acquisition of complementary businesses;
 
     - Consilium is established as a leader in providing semiconductor and
       electronics manufacturers a way to optimize fab performance, and an
       acquisition of Consilium would further Applied Materials' continued
       commitment to customers to improve overall equipment effectiveness and
       total productivity and will serve Applied Materials' primary business
       objective of providing Total Solutions(TM) to its customers; and
 
     - Applied Materials believes there is a significant potential enhancement
       of the strategic and market position of the combined entity beyond that
       achievable by Applied Materials alone.
 
     In addition to the reasons set forth above, in the course of its
deliberations concerning the merger, the Applied Materials Board of Directors
consulted with Applied Materials' management, financial advisors, legal counsel
and independent accountants and reviewed a number of other factors relevant to
the merger, including:
 
     - information concerning the business, assets, operations, properties,
       management, financial condition, operating results, competitive position
       and prospects of Applied Materials and Consilium;
 
     - the expected tax and accounting treatment of the merger; and
 
     - reports from legal counsel on specific terms of the merger agreement and
       the voting agreements executed by certain directors, officers and other
       stockholders of Consilium.
 
     The Applied Materials Board of Directors also considered a number of
potentially negative factors in its deliberations concerning the merger,
including:
 
     - the possibility of management disruption associated with the merger and
       the risk that key technical and management personnel of Consilium might
       not continue with Consilium;
 
     - the possibility that the merger might adversely affect Consilium's
       relationship with certain of its customers; and
 
     - the risk that the potential benefits of the merger might not be realized.
 
     The Applied Materials Board of Directors concluded, however, that the
benefits of the transaction to Applied Materials and its stockholders outweighed
the risks associated with the foregoing factors.
 
     The foregoing discussion of the information and factors considered by the
Applied Materials Board of Directors is not intended to be all-inclusive, 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 it considered. However, after taking into account all of
the factors set forth above, the Applied Materials Board of Directors agreed
that the merger agreement and the consummation of the merger were fair to, and
in the best interests of, Applied Materials and its stockholders and that
Applied Materials should proceed with the merger.

OPINION OF CONSILIUM'S FINANCIAL ADVISOR
 
     Consilium engaged Broadview International LLC ("Broadview") to act as its
financial advisor and requested that Broadview render an opinion regarding the
fairness, from a financial point of view, to Consilium's stockholders of the
exchange ratio. At the meeting of the Consilium Board of Directors on Monday,
October 12, 1998, Broadview rendered its written opinion (the "Broadview
Opinion") that, as of October 12, 1998, based upon and subject to the various
factors and assumptions set forth in the Broadview Opinion, the exchange ratio
was fair, from a financial point of view, to the Consilium stockholders. The
exchange ratio was determined pursuant to negotiations between Consilium and
Applied Materials and not pursuant to recommendations of Broadview.
 
     The text of the Broadview Opinion, which sets forth assumptions made,
matters considered, and limitations on the review undertaken, is attached as
Appendix B to this Proxy Statement/Prospectus. The summary of the Broadview
Opinion set forth in this Proxy Statement/Prospectus is qualified in its
entirety by reference to the full text of such opinion.
 
     In rendering its opinion, Broadview, among other actions: (i) reviewed the
terms of the merger agreement and the associated schedules thereto in the form
of the draft dated October 8, 1998 furnished to Broadview by Cooley Godward LLP
on October 9, 1998, which draft contained no material differences from the
definitive merger agreement; (ii) reviewed Consilium's Form 10-K for its fiscal
years ended October 31, 1996 and 1997, including the audited financial
statements included therein, and Consilium's Form 10-Q for the three and nine
months ended July 31, 1998, including the unaudited financial statements
included therein; (iii) reviewed quarterly financial projections for Consilium
for its fiscal years ending October 31, 1998, 1999 and 2000 prepared and
provided to Broadview by Consilium management; (iv) participated in discussions
with Consilium management concerning the operations, business strategy,
financial performance and prospects for Consilium; (v) discussed with Consilium
management its view of the strategic rationale for the merger; (vi) reviewed the
reported closing prices and trading activity for Consilium common stock; (vii)
compared certain aspects of the financial performance of Consilium with public
companies Broadview deemed comparable; (viii) analyzed available information,
both public and private, concerning other mergers and acquisitions Broadview
believed to be comparable in whole or in part to the merger; (ix) reviewed
Applied Materials' annual report and Form 10-K for its fiscal years ended
October 27, 1996 and October 26, 1997, including the audited financial
statements included therein, and Applied Materials' Form 10-Q for the three and
nine months ended July 26, 1998, including the unaudited financial statements
included therein; (x) participated in discussions with Applied Materials
management concerning the operations, business strategy, financial performance
and prospects for Applied Materials; (xi) discussed with Applied Materials'
management its view of the strategic rationale for the merger; (xii) reviewed
the reported closing prices and trading activity for Applied Materials common
stock; (xiii) compared certain aspects of the financial performance of Applied
Materials with public companies Broadview deemed comparable; (xiv) considered
the total number of shares of Applied Materials common stock outstanding and the
average weekly trading volume of Applied Materials common stock; (xv) reviewed
recent equity analyst reports covering Consilium and Applied Materials; (xvi)
analyzed the anticipated effect of the merger on the future financial
performance of the consolidated entity; and (xvii) conducted other financial
studies, analyses and investigations as Broadview deemed appropriate for
purposes of this opinion.
 
     In rendering the Broadview Opinion, Broadview relied, without independent
verification, on the accuracy and completeness of all the financial and other
information (including without limitation the representations and warranties
contained in the merger agreement) that was publicly available or furnished by
Consilium, Applied Materials, or Applied Materials' financial advisor. Broadview
assumed that those projections prepared and provided by Consilium were
reasonably prepared and reflected the best available estimates and good faith
judgments of the management of Consilium as to the future performance of
Consilium. Broadview did not make or obtain an independent appraisal or
valuation of any of Consilium's assets. With regard to any analyses relating to
valuations of comparable public companies, the share prices used were for the
close of trading on October 9, 1998, the last trading day before the Consilium
board of directors met to give final consideration to the proposed merger.
Broadview also assumed that the transactions described in the merger agreement
would be consummated on the terms set forth in the merger agreement.
 
                                       29
<PAGE>   36
 
     The following is a summary explanation of the various sources of
information and valuation methodologies employed by Broadview in conjunction
with rendering the Broadview Opinion regarding the proposed merger.
 
PUBLIC COMPANY COMPARABLES ANALYSIS
 
     Total Market Capitalization/Revenue ("TMC/R") and Price/Earnings ("P/E")
multiples indicate the value public markets place on companies in a particular
market segment. A handful of companies are comparable to Consilium based on
business model and products offered. Broadview reviewed seven public company
comparables in the industrial automation software industry from a financial
point of view including each company's: Trailing Twelve Month ("TTM") Revenue;
TTM Revenue Growth; Projected Calendar Year 1999 Revenue ("Forward 1999
Revenue"); TTM Pretax Margin; Equity Market Capitalization; TTM P/E ratio;
Price/Projected Calendar Year 1999 EPS ratio ("Forward 1999 P/E"); TTM TMC/R
ratio; TMC/Last Quarter Annualized Revenue ("LQA TMC/R"); and TMC/Forward
Calendar Year 1999 Revenue ratio ("Forward 1999 TMC/R") ratio. The public
company comparables were selected from the Broadview Barometer, a proprietary
database of publicly-traded Information Technology ("IT") companies maintained
by Broadview and broken down by industry segment. In order of descending TTM
TMC/R, the public company comparables consist of: (i) Datastream Systems, Inc.;
(ii) USDATA Corp.; (iii) Aspen Technology, Inc.; (iv) Project Software and
Development, Inc.; (v) Promis Systems Corp.; (vi) Indus International, Inc.; and
(vii) Gensym Corp. The comparables have a TTM P/E ratio range of 7.0 to 20.3
with a median of 8.1; Forward 1999 P/E ratio range of 5.2 to 14.1 with a median
of 7.5; TTM TMC/R ratio range of 0.0 to 3.2 with a median of 0.7; LQA TMC/R
ratio range of 0.0 to 2.8 with a median of 0.6; Forward 1999 TMC/R ratio range
of 0.0 to 2.1 with a median of 0.5.
 
     The per share valuation range implied by the TTM P/E multiples is not
meaningful due to an aggregate net operating loss suffered by the Semiconductor
and Electronics Division of Consilium for the period included in the calculation
of TTM Net Income. The per share valuation range implied by the Forward 1999 P/E
multiples is $1.62 to $4.39 with a median implied value of $2.33. The per share
valuation range implied by the TTM TMC/R multiples is $0.44 to $10.16 with a
median implied value of $2.57. The per share valuation range implied by the LQA
TMC/R multiples is $0.44 to $8.76 with a median implied value of $2.29. The per
share valuation range implied by the Forward 1999 TMC/R multiples is $0.45 to
$7.39 with a median implied value of $2.14.
 
TRANSACTION COMPARABLES ANALYSIS
 
     Valuation statistics from transaction comparables indicate the Adjusted
Price/Revenue ("P/R") multiple acquirers have paid for comparable companies in a
particular market segment. Broadview reviewed 12 comparable merger and
acquisition ("M&A") transactions from January 1, 1996 through October 9, 1998
involving sellers in the industrial automation software industry. Transactions
were selected from Broadview's proprietary database of published and
confidential M&A transactions in the IT industry. In order of descending P/R
multiple, the transactions used are the acquisition of: (i) Innovative Tech
Systems, Inc. by Peregrine Systems, Inc.; (ii) TSW International, Inc. by Indus
Group, Inc.; (iii) Wonderware Corp. by Siebe Plc; (iv) Hyprotech, Ltd. by AEA
Technology Plc; (v) Simulation Sciences, Inc. by Siebe Plc; (vi) SQL Systems
Group BV by Datastream Systems, Inc.; (vii) Maintenance Automation Corp. by
Project Software and Development, Inc.; (viii) Process Industries Modeling
System Business of Bechtel Group, Inc. by Aspen Technology, Inc.; (ix) Dynamic
Matrix Control Corp. by Aspen Technology, Inc.; (x) Insta Instandhaltung
Technischer Anlagen GmbH by Datastream Systems, Inc.; (xi) Revere, Inc. by
Walker Interactive Systems, Inc.; and (xii) Cegelec-Setpoint, Inc. (subsidiary
of Alcatel Alsthom) by Aspen Technology, Inc. The P/R multiples of the 12
transactions range from 0.6 to 5.5 with a median of 2.2.
 
     The per share valuation range implied by the P/R multiples is $2.26 to
$17.12 with a median implied value of $7.00.
 
                                       30
<PAGE>   37
 
TRANSACTION PREMIUMS PAID ANALYSIS
 
     Premiums paid in comparable public seller transactions indicate the amount
of consideration acquirers are willing to pay above the seller's equity market
capitalization. In this analysis, the value of consideration paid in
transactions involving stock is computed using the buyer's stock price
immediately prior to announcement (closing price as quoted on the appropriate
exchange the trading day prior to announcement). The seller's equity market
capitalization is measured one trading day prior and twenty trading days prior
to announcement. Broadview reviewed 27 comparable M&A transactions involving
North American software vendors from January 1, 1996 through October 9, 1998
with total consideration between $10 million and $100 million. Transactions were
selected from Broadview's proprietary database of published and confidential M&A
transactions in the IT industry. In order of descending premium paid to seller's
equity market capitalization 20 trading days prior to the date of announcement,
the software transactions used were the acquisition of: (i) Softdesk, Inc. by
Autodesk, Inc.; (ii) EveryWare Development, Inc. by Pervasive Software, Inc.;
(iii) High Level Design Systems, Inc. by Cadence Design Systems, Inc.; (iv)
Accugraph Corp. by Architel Systems Corp.; (v) CUSA Technologies by Fiserv,
Inc.; (vi) National Health Enhancement Systems, Inc. by HBO & Company; (vii)
Interactive Group by Dataworks Corp.; (viii) TGV Software, Inc. by Cisco
Systems, Inc.; (ix) Software Publishing Corp. by Allegro New Media, Inc.; (x)
Open Environment Corp. by Borland International, Inc.; (xi) Datalogix
International, Inc. by Oracle Corp.; (xii) Kurzweil Applied Intelligence, Inc.
by Lernout & Hauspie Speech Product NV; (xiii) Maxis, Inc. by Electronic Arts,
Inc.; (xiv) Learmonth & Burchett Management Systems, Inc. by PLATINUM
technology, inc.; (xv) Medicus Systems by QuadraMed Corp.; (xvi) Milkyway
Networks Corp. by SLM Software, Inc.; (xvii) TeleBackup Systems, Inc. by VERITAS
Software Corp.; (xviii) Innovative Tech Systems, Inc. by Peregrine Systems,
Inc.; (xix) Andyne Computing Ltd. by Hummingbird Communications Ltd.; (xx) IQ
Software Corp. by Information Advantage Software, Inc.; (xxi) Versatility, Inc.
by Oracle Corp.; (xxii) Orcad, Inc. by Summit Design, Inc.; (xxiii) Compurad,
Inc. by Lumisys, Inc.; (xxiv) Fulcrum Technologies, Inc. by PC DOCS Group
International, Inc.; (xxv) FTP Software, Inc. by NetManage, Inc.; (xxvi) Firefox
Communications, Inc. by FTP Software, Inc.; and (xxvii) Cayenne Software, Inc.
by Sterling Software, Inc. Based upon Broadview's analysis of premiums paid in
comparable software transactions, Broadview found that premiums or (discounts)
paid to the sellers' equity market capitalizations 20 trading days prior to the
announce date ranged from (53.9%) to 172.7% with a median of 37.0%. The premiums
or (discounts) paid to the sellers' equity market capitalization one day prior
to the announce date ranged from (14.4%) to 99.9% with a median of 27.0%.
 
     The per share valuation range implied by the premiums paid to the share
price 20 days prior to announcement is $0.81 to $4.77 with a median implied
value of $2.40. The per share valuation range implied by the premiums paid to
the share price one day prior to announcement is $1.50 to $3.50 with a median
implied value of $2.22.
 
PRESENT VALUE OF PROJECTED SHARE PRICE ANALYSIS
 
     Broadview calculated the present value of the potential future price of
shares of Consilium common stock on a standalone basis using management
projections for the twelve month period ending January 31, 2000 discounted to
today at discount rates from 10.0% to 25.0%. The potential future share price is
calculated based on earnings estimates (as projected by Consilium management)
for the 12 months ending January 31, 2000 and assumes TTM P/E multiples of
between 6.0x and 11.0x, in line with comparable public company multiples for
Consilium. Based on this analysis, the per share valuation range implied by the
present value of the future share prices is $1.10 to $2.73. The implied share
price calculated using the median P/E for the public company comparables and
discounted based on CAPM and the median capital-structure adjusted beta for the
public company comparables equals $1.85.
 
EXCHANGE RATIO ANALYSIS
 
     Broadview considered the relative value public equity markets have placed
on Consilium and Applied Materials common stock from October 3, 1997 through
October 9, 1998. For comparative purposes, the implied historical exchange ratio
was examined in contrast to the exchange ratio defined in the merger
 
                                       31
<PAGE>   38
 
agreement. Based on this analysis the historical exchange ratio has ranged from
0.0508 to 0.1276 during the 12 months ending October 9, 1998. The average
historical exchange ratio over this period has been 0.0856.
 
     Based on Applied Materials' stock price of $23.625 on October 9, 1998, the
per share valuation range implied by the historical exchange ratio analysis is
$1.20 to $3.01 with an average implied value of $2.02.
 
STOCK PERFORMANCE ANALYSIS
 
     For comparative purposes, Broadview examined the trading history of: (i)
Consilium Common Stock from October 3, 1997 through October 9, 1998; and (ii) an
index of the public company comparables vs. Consilium and the S&P 500 from
October 3, 1997 through October 9, 1998.
 
EVALUATION OF APPLIED MATERIALS EQUITY
 
     Broadview compared selected valuation multiples for public companies deemed
comparable to Applied Materials based upon revenue size and product offering,
with the multiples implied by Applied Materials' October 9, 1998 share price of
$23.625, and its current and projected performance. Broadview reviewed four
public companies in the front-end semiconductor manufacturing equipment markets
with TTM Revenues greater than $500 million from a financial point of view. In
order of descending TTM TMC/R, the public company comparables consist of: (i)
KLA-Tencor Corp.; (ii) Novellus Systems, Inc.; (iii) LAM Research Corp.; and
(iv) Silicon Valley Group, Inc.
 
STOCK PERFORMANCE ANALYSIS
 
     For comparative purposes, Broadview examined the trading history of: (i)
Applied Materials common stock from October 3, 1997 through October 9, 1998; and
(ii) an index of the public company comparables vs. Applied Materials and the
S&P 500 from October 3, 1997 through October 9, 1998.
 
PRO FORMA COMBINATION ANALYSES
 
     A pro forma merger analysis calculates the EPS accretion/dilution of the
pro forma combined entity taking into consideration various financial effects
which will result from a consummation of the merger. This analysis relies upon
certain financial and operating assumptions provided by equity research
analysts, publicly available data about Applied Materials, and management's
projections for Consilium. Broadview examined a pooling scenario under the
assumptions given to Broadview by Consilium and Applied Materials management.
Based on analyst estimates for Applied Materials and management projections for
Consilium, the pro forma pooling model indicates EPS accretion, excluding
acquisition expenses, for the fiscal year ending October 31, 1999 of 1.1%.
 
CONSIDERATION OF THE DISCOUNTED CASH FLOW VALUATION METHODOLOGY
 
     While discounted cash flow is a commonly used valuation methodology,
Broadview did not employ such an analysis for the purposes of this opinion.
Discounted cash flow analysis is most appropriate for companies which exhibit
relatively steady or somewhat predictable streams of future cash flow. Given the
uncertainty in estimating both the future cash flows and a sustainable long-term
growth rate for Consilium, Broadview considered a discounted cash flow analysis
inappropriate for valuing Consilium.
 
SUMMARY OF VALUATION ANALYSES
 
     Taken together, the information and analyses employed by Broadview lead to
Broadview's overall opinion that the exchange ratio is fair from a financial
point of view, to Consilium stockholders.
 
     The Consilium Board of Directors selected Broadview as its financial
advisor on the basis of Broadview's reputation and experience in the information
technology sector and the computer software industry in particular. Pursuant to
the terms of an engagement letter between Consilium and Broadview, the fees
payable by Consilium to Broadview upon delivery of the opinion are fixed.
Broadview will be reimbursed by Consilium for certain of its expenses incurred

Broadview, which Consilium and Broadview believe are customary in transactions
of this nature, were negotiated at arms' length between Consilium and Broadview,
and the Consilium Board of Directors was aware of the nature of the fee
arrangement. Consilium has agreed to indemnify Broadview and its affiliates,
their respective members, directors, officers, agents, employees and legal
representatives, and each person controlling Broadview or its affiliates,
against certain liabilities and expenses, including liabilities under the
federal securities laws arising out of or in connection with Broadview's
engagement by Consilium.
 
     The above summary of the presentations by Broadview to the Consilium Board
of Directors does not purport to be a complete description of such presentations
or of all the advice rendered by Broadview. Broadview believes that its analyses
and the summary set forth above must be considered as a whole and that selecting
portions of its analyses, without considering all analyses, could create an
incomplete view of the process underlying the analyses set forth in Broadview's
presentations to the Consilium Board of Directors and in the Broadview Opinion.
The Broadview Opinion is necessarily based upon market, economic, financial and
other conditions as they existed and could be evaluated as of the date of the
Broadview Opinion. The Broadview Opinion expresses no opinion as to the price at
which Applied Materials common stock will trade at any time. In performing its
analyses, Broadview made numerous assumptions with respect to software industry
performance, semiconductor manufacturing equipment industry performance and
general economic conditions, many of which are beyond the control of Consilium
or Applied Materials. The analyses performed by Broadview are not necessarily
indicative of actual values or actual future results, which may be significantly
more or less favorable than suggested by such analyses.
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
OFFICERS AND DIRECTORS OF CONSILIUM
 
     Certain members of Consilium's management and Board of Directors may be
deemed to have certain interests in the merger that are in addition to their
interests as stockholders of Consilium generally. The Consilium Board of
Directors was aware of these interests and considered them, among other matters,
in approving the merger agreement and the transactions contemplated thereby.
 
INDEMNIFICATION AND INSURANCE
 
     Pursuant to the merger agreement, all rights to indemnification existing in
favor of those persons who are directors and officers of Consilium as of the
date of the merger agreement (the "Indemnified Persons") for acts and omissions
occurring prior to the effective time of the merger, as provided in Consilium's
Bylaws (as in effect as of the date of the merger agreement) and as provided in
the indemnification agreements between Consilium and said Indemnified Persons
(as in effect as of the date of the merger agreement), shall survive the merger
and shall be observed by Consilium following the effective time of the merger
(the "Surviving Corporation") to the fullest extent available under DGCL for a
period of five years from the effective time of the merger. The merger agreement
also provides that from the effective time of the merger until the fifth
anniversary of the effective time of the merger, 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 of the merger, the
existing policy of directors' and officers' liability insurance maintained by
Consilium as of the date of the merger 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 an annual premium for the
Existing Policy (or for any substitute policies) in excess of $168,750. In the
event any future annual premium for the Existing Policy (or any substitute
policies) exceeds $168,750, 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
$168,750. According the merger agreement, if the Surviving Corporation does not
have sufficient capital to comply with its obligations described in this
paragraph, Applied Materials shall provide the Surviving Corporation with such
capital. See "The Merger Agreement -- Indemnification and Insurance."

CHANGE OF CONTROL AGREEMENTS; STOCK OPTION ACCELERATION
 
     In December 1996, Consilium's Compensation Committee of the Board of
Directors approved and ratified, a form of change of control agreement for use
with officers of Consilium. On December 11, 1996, Consilium entered into Change
of Control Agreements (as such term is defined in the merger agreement) with the
following persons: Jonathan Golovin (its Chairman of the Board and Chief
Technical Officer), Laurence Hootnick (its President and Chief Executive
Officer), Michael Field (its Senior Vice President and Chief Administrative
Officer), Clifton Wong (its Vice President, Finance and Chief Financial Officer)
and Frank Kaplan (its Senior Vice President, SW Development and Quality
Assurance). On June 16, 1997, Consilium entered into a Change of Control
Agreement with Richard Danielson (its Vice President, Marketing). It is
contemplated that Mr. Golovin will enter into a Resignation Agreement and
General Release of Claims, pursuant to which in exchange for certain benefits
described below, Mr. Golovin will waive all of his rights to severance payments
(but not his rights with respect to the acceleration of the vesting of his stock
options) under his Change of Control Agreement. See "-- Resignation Agreement
and General Release of Claims -- Jonathan Golovin." Mr. Golovin is entitled
(under the portion of his Change of Control Agreement not waived by Mr. Golovin)
to receive a credit of 24 months service for purposes of determining the vesting
and exercisability of stock options held by him immediately prior to the
consummation of a Change of Control.
 
     The Change of Control Agreement with Mr. Hootnick provides that (i) in the
event of any Involuntary Termination (as such term is defined in the Change Of
Control Agreements) of Mr. Hootnick's employment with Consilium within 12 months
after a Change of Control (as such term is defined in the Change of Control
Agreements) of Consilium, Mr. Hootnick is entitled to receive (A) severance pay
equal to 200% of his annual base salary at the time of termination, (B) the full
amount of the annual bonus at the "on-target" level for the fiscal year in which
the Involuntary Termination occurs and (C) up to 12 months COBRA reimbursement,
and (ii) in the event of a Change of Control of Consilium, Mr. Hootnick is
entitled to receive a credit of 24 months continuous service for purposes of
determining the vesting and exercisability of stock options held by him
immediately prior to the Change of Control. Messrs. Field, Wong, Kaplan and
Danielson's Change of Control Agreements are similar to the Change of Control
Agreements entered into by Mr. Hootnick, except that (i) in the event of
Involuntary Termination within 12 months of a Change of Control, Messrs. Field,
Wong, Kaplan and Danielson are entitled to receive (A) severance pay equal to
100% of their respective annual base salary, (B) the annual bonus at the
"on-target level" for the year in which the Involuntary Termination occurs, and
(C) up to 12 months COBRA reimbursement, and (ii) in the event of a Change of
Control, Messrs. Field, Wong, Kaplan and Danielson are entitled to receive
credit of 12 months service for purposes of determining the vesting and
exercisability of their respective stock options. The merger would constitute a
Change of Control for purposes of the Change of Control Agreements.
 
     All stock options outstanding under Consilium's 1990 Outside Directors'
Stock Option Plan contain terms that provide that vesting of all such options
will accelerate immediately prior to a change of control of Consilium. The
merger constitutes such a change of control.
 
     Assuming that the merger was consummated on October 12, 1998, the following
table shows the number of unvested options that would have been held by each of
Messrs. Golovin, Hootnick, Field, Wong, Kaplan
 
                                       34

and Danielson and each director of Consilium immediately prior to the
consummation of the merger, which will become fully vested as a result of the
consummation of the merger:

RESIGNATION AGREEMENT AND GENERAL RELEASE OF CLAIMS
 
     Applied Materials has required Jonathan J. Golovin to enter into a
Resignation Agreement between Golovin, Consilium and Applied Materials (the
"Resignation Agreement"). The Resignation Agreement shall become effective as of
the closing of the Merger. The Resignation Agreement provides that (i) Golovin
shall resign as a director of Consilium and member of the Board and as Chairman
of the Board, Consilium may change or remove any of Golovin's titles at any time
and Golovin shall resign from his employment and as an officer of Consilium
effective January 31, 2000 (the "Resignation Date"); (ii) until the Resignation
Date, Golovin will continue to perform services for Consilium and will be
obligated to provide no more than approximately 30 working hours for Consilium
per month, Golovin will not be eligible to participate in any of Consilium's
bonus programs (except that Consilium agrees to pay him any bonus of up to
$85,000 he would otherwise have received for his work for Consilium during
fiscal year 1998) and Golovin will not be eligible to participate in any of
Consilium's employee benefit plans or programs once he begins working less than
120 hours per month; (iii) until the Resignation Date Consilium will provide
Golovin with the following salary and benefits: (A) $250,000 per year, (this
benefit is also payable to his heirs in the event of his death or disability)
(B) COBRA continued medical, dental and vision insurance coverage at Consilium's
expense (this benefit is also payable to his heirs in the event of his death or
disability), (C) current voicemail box, existing email account and reimbursement
for expenses reasonably incurred by him in his activities undertaken at
Consilium's request, (D) secretarial support and use of an office, (E) personal

previously provided for his use, (G) continued reimbursement for state license
fees and regular monthly lease payments each in an amount no greater than
$1,056.69 for Golovin's current vehicle (including lease payments made in
February, March and April 2000 after the Resignation Date) and vehicle insurance
coverage at a cost not greater than the premium for such coverage paid by
Consilium in 1998 for Golovin; (iv) a stock option granted on May 19, 1997 for
50,000 shares of Consilium common stock, which is partially vested, will
immediately vest in full upon and simultaneous with the closing of the merger,
such acceleration being identical with the original terms of his Change of
Control Agreement; (v) upon consummation of the merger, Mr. Golovin will receive
a credit of 24 months service for purposes of determining the vesting and
exercisability of stock options held by him immediately prior to the
consummation of a Change of Control, such credit being identical with the
original terms of his Change of Control Agreement; (vi) Golovin's employment may
be terminated by Consilium before the Resignation Date, in the event of the
following: (A) theft, dishonesty, misconduct or intentional falsification of any
employment or Consilium records by Golovin, (B) intentional and improper use or
disclosure of the Company's confidential or proprietary information by Golovin,
or (C) Golovin's failure or inability to perform any duties reasonably requested
by Consilium, or any breach of the Resignation Agreement, provided that Golovin
has been given written notice of, and a reasonable opportunity to cure, such
failure or inability or breach; and (vii) Golovin releases and absolutely
discharges Consilium and Applied Materials and related parties from any and all
claims, actions and causes of action, which Golovin now has, or at any time had,
or shall or may have against released parties.

     Mr. Golovin is permitted to provide services (including membership on the
Board of Directors) to Vigilance, Inc. without any effect on the benefits
provided pursuant to the Resignation Agreement.
 
OFFICERS AND DIRECTORS OF APPLIED MATERIALS
 
     No officer or director of Applied Materials has any interest in the merger
that is in addition to his or her interest as a stockholder of Applied Materials
generally.
 
VOTING AGREEMENTS
 
     Pursuant to the Voting Agreements, Centennial Associates, L.P. and all of
Consilium's directors and executive officers, who own in the aggregate issued
and outstanding shares of Consilium common stock representing approximately
40.97% of the shares of Consilium common stock issued and outstanding as of the
Record Date, have agreed that, prior to the earlier of the effective time of the
merger or the termination of the merger agreement, they will vote their shares
of Consilium common stock in favor of: (i) the merger; (ii) the adoption and
approval of the terms of the merger agreement; and (iii) each of the other
actions contemplated by the merger agreement. Each of the stockholders who
entered into a Voting Agreement has also delivered to Applied Materials
irrevocable proxies with respect to the matters covered by the Voting
Agreements. In addition, each of the stockholders who entered into a Voting
Agreement has agreed that prior to the earlier of the effective time of the
merger or termination of the merger agreement, they will not transfer any
Consilium securities owned by such stockholder unless and until the proposed
transferee of such securities has (i) executed a counterpart of the Voting
Agreement and the corresponding irrevocable proxy and (ii) agreed to hold such
securities subject to all of the terms and conditions of the Voting Agreement.
 
     Each of the stockholders who entered into a Voting Agreement has also
agreed that, during the period commencing on the date of the Voting Agreement
and ending on the earlier of the effective time of the merger or the termination
of the merger agreement, such stockholder will not, in his capacity as a
stockholder and not in his capacity as a director or officer of Consilium,
directly or indirectly, and will not authorize any of such stockholder's
representatives to: (i) solicit, initiate or encourage the making, submission or
announcement of an Acquisition Proposal (as defined below) or take any action
that could reasonably be expected to lead to an Acquisition Proposal; (ii)
furnish any nonpublic information regarding Consilium or any direct or indirect
subsidiary of Consilium to any person in connection or in response to an
Acquisition Proposal or potential Acquisition Proposal; or (iii) engage in
discussions with any person with respect to an Acquisition Proposal. All
Consilium directors have also agreed to cease any existing discussions with any
person that relate to an Acquisition Proposal.
 
     The merger agreement defines (i) Acquisition Proposal as any offer,
proposal or inquiry (other than an offer or proposal by Applied Materials)
contemplating or otherwise relating to any Acquisition Transaction, and (ii)
"Acquisition Transaction" as any transaction or series of transactions
involving: (A) any merger, consolidation, amalgamation, share exchange, business
combination, issuance of securities, acquisition of securities, tender offer,
exchange offer or other similar transaction (1) in which Consilium or any of its
subsidiaries is a constituent company, (2) in which a person or "group" (as
defined in the Exchange Act and the rules promulgated thereunder) of persons
directly or indirectly acquires Consilium or more than 40% of Consilium's
business or directly or indirectly acquires beneficial or record ownership of
securities representing, or exchangeable for or convertible into, more than 40%
of the outstanding securities of any class of voting securities of Consilium or
any of its subsidiaries, or (3) in which Consilium or any of its subsidiaries
issues securities representing more than 40% of the outstanding securities of
any class of voting securities of Consilium; (B) any sale, lease, exchange,
transfer, license, acquisition or disposition of more than 40% of the assets of
Consilium; or (C) any liquidation or dissolution of Consilium.
 
AFFILIATE AGREEMENTS
 
     It is a condition to consummation of the merger that each person who could
reasonably be determined to be an "affiliate" (as such term is defined in Rule
145 promulgated under the Securities Act) of Consilium ("Affiliate") execute an
agreement that prohibits, during the period from the date 30 days prior to the
date of
 
                                       36
<PAGE>   43
 
consummation of the merger through the date on which financial results covering
at least 30 days of post-merger combined operations of Applied Materials and
Consilium have been published by Applied Materials (within the meaning of the
applicable pooling of interests accounting requirements): (i) the sale, transfer
or other disposition or reduction of such Affiliate's interest in or risk
relating to (A) any capital stock of Consilium, except pursuant to and upon
consummation of the merger, or (B) any option or other right to purchase any
shares of capital stock of Consilium, except pursuant to and upon consummation
of the merger; and (ii) the sale, transfer or other disposition or reduction of
such Affiliate's interest in or risk relating to (a) any shares of capital stock
of Applied Materials or (b) any option or other right to purchase any shares of
capital stock of Applied Materials.
 
NONCOMPETITION AGREEMENTS
 
     Jonathan J. Golovin and Laurence R. Hootnick (the "Noncompete Employees"),
each have entered into a Noncompetition Agreement with Applied Materials (a
"Noncompetition Agreement"). The Noncompetition Agreements contain provisions
restricting such Noncompete Employees, for two years following the effective
time of the merger, from:
 
     - subject to certain exceptions, engaging in, or being an officer,
       director, stockholder, owner, partner, employee, manager, agent, advisor
       or consultant of or to, or participate in the ownership, management,
       operation, control or financing of, any entity that engages in:
 
        - any business or activity involving (directly or indirectly) the (A)
          design, development, manufacture, marketing or distribution (whether
          by sale or license or otherwise) of manufacturing executions systems
          software or other software or products that track, correlate data with
          respect to and/or automate manufacturing operations in the
          semiconductor and flat panel display industries, (B) provision or
          performance of automated factory systems and software integration
          services in the semiconductor and flat panel display industries; or
          (C) provision or performance of services (including training,
          technical support or maintenance services) related to any of the
          products referred to in this paragraph;
 
        - any other business or activity that is competitive with the business
          or activities engaged in or proposed to be engaged in by Consilium or
          any of its direct or indirect subsidiaries as of the effective date of
          the merger in the semiconductor or flat panel display industries; or
 
        - any business or activity that is competitive with the business or
          activities of Applied Materials, Consilium, any of Consilium's direct
          or indirect subsidiaries or any of Applied Materials' other direct or
          indirect subsidiaries at any time after the effective date of the
          merger during which the Noncompete Employee is an employee of, or
          consultant or advisor to, Applied Materials, Consilium or any of
          Applied Materials' other direct or indirect subsidiaries;
 
     - subject to certain exceptions, hiring certain specified employees or
       recruiting, encouraging, inducing, attempting to induce, soliciting or
       attempting to solicit any specified employee to leave his or her
       employment with Applied Materials, Consilium, any of Consilium's direct
       or indirect subsidiaries or any of Applied Materials' other direct or
       indirect subsidiaries; and
 
     - using any trade secret of Applied Materials, Consilium, any of
       Consilium's direct or indirect subsidiaries or any of Applied Materials'
       other direct or indirect subsidiaries, or any other improper means, to
       interfere or attempt to interfere with the relationship or prospective
       relationship of Consilium, any of Consilium's direct or indirect
       subsidiaries, Applied Materials or any of Applied Materials' direct or
       indirect subsidiaries, with any person or entity that is, was or is
       expected to become a customer or client of Consilium, any of Consilium's
       direct or indirect subsidiaries, Applied Materials or any of Applied
       Materials' direct or indirect subsidiaries.
 
MATERIAL FEDERAL INCOME TAX CONSEQUENCES
 
     The following discussion summarizes the material federal income tax
considerations of the merger that are generally applicable to holders of
Consilium common stock. This discussion is based on currently existing
 
                                       37
<PAGE>   44
 
provisions of the Internal Revenue Code of 1986, as amended (the "Code"),
existing and proposed Treasury Regulations thereunder and current administrative
rulings and court decisions, all of which are subject to change. Any such
change, which may or may not be retroactive, could alter the tax consequences to
Applied Materials, Consilium or Consilium stockholders as described herein.
 
     Consilium stockholders should be aware that this discussion does not deal
with all U.S. federal income tax considerations that may be relevant to
particular Consilium stockholders in light of their particular circumstances,
such as stockholders who are dealers in securities, banks, insurance companies
or tax-exempt organizations, who are subject to the alternative minimum tax
provisions of the Code, who are foreign persons, who acquired their shares in
connection with stock option or stock purchase plans or in other compensatory
transactions or who hold their shares as a hedge or as part of a hedging,
straddle or other risk reduction strategy. In addition, the following discussion
does not address the tax consequences of the merger under foreign, state or
local tax laws or the tax consequences of transactions effectuated prior to or
after the merger (whether or not such transactions are in connection with the
merger).
 
     CONSILIUM STOCKHOLDERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS AS TO
THE SPECIFIC CONSEQUENCES OF THE MERGER, INCLUDING THE APPLICABLE FEDERAL,
STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO THEM OF THE MERGER IN THEIR
PARTICULAR CIRCUMSTANCES.
 
     Neither Applied Materials nor Consilium has requested a ruling from the
Internal Revenue Service (the "IRS") with regard to any of the U.S. federal
income tax consequences of the merger. Gray Cary Ware & Freidenrich LLP ("Gray
Cary"), counsel to Consilium, and Cooley Godward LLP ("Cooley Godward"), counsel
to Applied Materials, have each rendered an opinion (collectively, the "Tax
Opinions") that the merger will constitute a reorganization under Section 368(a)
of the Code (a "Reorganization"). As a condition to the consummation of the
merger, such counsel must also render tax opinions at the closing of the merger
that the merger will constitute a Reorganization (the "Closing Opinions").
 
     The Tax Opinions and the Closing Opinions, assume and are conditioned upon
(i) the truth and accuracy of the statements, covenants, representations and
warranties contained in the merger agreement, in the representations received
from Applied Materials, Merger Sub and Consilium to support the Tax Opinions and
the Closing Opinions (the "Tax Representations") and in all other instruments
and documents related to the formation, organization and operation of Applied
Materials, Merger Sub and Consilium examined by and relied upon by Cooley
Godward and Gray Cary in connection with the merger; (ii) that original
documents submitted to such counsel are authentic, documents submitted to such
counsel 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; (iii) that all covenants contained in the merger
agreement and the Tax Representations are performed without waiver or breach of
any material provision thereof; and (iv) that any representation or statement
made "to the best of knowledge" or similarly qualified is correct without such
qualification.
 
     Subject to the limitations and qualifications referred to herein and in the
Tax Opinions and Closing Opinions, and assuming the merger is treated as a
Reorganization in accordance with the Tax Opinions and the Closing Opinions, the
following U.S. federal income tax consequences will result:
 
     - no gain or loss will be recognized by the holders of Consilium common
       stock upon the receipt of Applied Materials common stock solely in
       exchange for such Consilium common stock in the merger (except in respect
       of cash received in lieu of fractional shares of Applied Materials common
       stock, as discussed below);
 
     - the aggregate tax basis of the Applied Materials common stock so received
       by Consilium stockholders in the merger (including any fractional share
       of Applied Materials common stock deemed to be received as discussed
       below) will be the same as the aggregate tax basis of Consilium common
       stock surrendered in exchange therefor;
 
     - the holding period of the Applied Materials common stock so received by
       each Consilium stockholder in the merger will include the period for
       which the Consilium common stock surrendered in exchange
 
                                       38
<PAGE>   45
 
       therefor was considered to be held, provided that the Consilium common
       stock so surrendered is held as a capital asset at the effective time of
       the merger;
 
     - cash payments received by holders of Consilium common stock in lieu of a
       fractional share will be treated as if such fractional share of Applied
       Materials common stock had been issued in the merger and then redeemed by
       Applied Materials. A Consilium stockholder receiving such cash will
       generally recognize gain or loss upon such payment, measured by the
       difference (if any) between the amount of cash received and the basis in
       such fractional share. The gain or loss should be capital gain or loss
       provided that such share of Consilium common stock was held as a capital
       asset at the effective time of the merger; and
 
     - neither Applied Materials nor Consilium will recognize a gain solely as a
       result of the merger.
 
     Irrespective of the Reorganization status of the merger, a recipient of
shares of Applied Materials common stock would recognize income or gain to the
extent such shares were considered to be received in exchange for services or
property other than solely Consilium common stock. Gain would also be recognized
to the extent a Consilium stockholder was treated as receiving (directly or
indirectly) consideration other than Applied Materials common stock in exchange
for such stockholder's Consilium common stock.
 
     A successful IRS challenge to the Reorganization status of the merger would
result in significant adverse tax consequences to the Consilium stockholders. A
Consilium stockholder would recognize gain or loss with respect to each share of
Consilium common stock surrendered equal to the difference between the
stockholder's basis in such share and the sum of the fair market value, as of
the effective time of the merger, of the Applied Materials common stock received
in exchange therefor and cash received in lieu of fractional shares of the
Applied Materials common stock. In such event, a stockholder's aggregate basis
in the Applied Materials common stock so received would equal its fair market
value as of the effective time, and the stockholder's holding period for such
stock would begin the day after the closing date of the merger.
 
     Consilium stockholders will be required to attach a statement to their
federal income tax returns for the year of the merger that contains the
information listed in Treasury Regulation Section 1.368-3(b). Such statement
must include the stockholder's tax basis in the stockholder's Consilium common
stock and a description of the Applied Materials common stock received.
 
ANTICIPATED ACCOUNTING TREATMENT
 
     The merger is intended to be accounted for as a pooling of interests for
financial reporting purposes in accordance with generally accepted accounting
principles. Applied Materials' obligation to consummate the merger is
conditioned upon receipt of: (a) a letter from Arthur Andersen LLP, dated as of
the closing date of the merger and addressed to Consilium, reasonably
satisfactory in form and substance to Applied Materials and
PricewaterhouseCoopers LLP, to the effect that Arthur Andersen LLP concurs with
Consilium management's conclusion that Consilium is not aware of any fact
concerning Consilium or any of its subsidiaries or any of the stockholders or
affiliates of Consilium or any of its subsidiaries that could preclude Consilium
from being a "poolable entity" in accordance with generally accepted accounting
principles, Accounting Principles Board Opinion No. 16 and all published rules,
regulations and policies of the SEC; and (b) a letter from
PricewaterhouseCoopers LLP, dated as of the closing date of the merger and
addressed to Applied Materials, reasonably satisfactory in form and substance to
Applied Materials, to the effect that PricewaterhouseCoopers LLP concurs with
Applied Materials management's conclusion that Applied Materials may account 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. Applied Materials has the
right to waive the condition that the merger be accounted for as a pooling of
interests. If the merger is consummated but fails to qualify for pooling of
interests accounting treatment, the transaction would be accounted for as a
purchase. Accounting for the merger as a purchase would require Applied
Materials to record certain intangible assets and charges against future results
of operations in connection with the acquisition, which could adversely affect
Applied Materials' results of operations.

REGULATORY MATTERS
 
     Under the HSR Act and the rules promulgated thereunder, the merger may not
be consummated until notifications have been given and certain information has
been furnished to 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 Consilium. Applied Materials and
Consilium filed notification and report forms under the HSR Act with the FTC and
the Antitrust Division on October 22, 1998. These filings commenced a 30-day
waiting period under the HSR Act. If, prior to the expiration of such period,
the FTC or the Antitrust Division should request additional information or
documentary material under the HSR Act, consummation of the merger could be
delayed until after the companies have substantially complied with the request.
Under the German anticompetition law (the "GWB") and the rules promulgated
thereunder, the merger may not be consummated until notifications have been
given and certain information has been furnished to the Federal Cartel Office
and specified waiting period requirements have been satisfied or early
termination of the waiting period is granted at the request of Applied Materials
and Consilium. Applied Materials and Consilium filed notification and report
forms under the HSR Act with the FTC and the Antitrust Division on October 22,
1998, and will file a report under the GWB. These filings commenced and will
commence a 30-day waiting period under the HSR Act and the GWB. If, prior to the
expiration of such period, the FTC, the Antitrust Division or the Federal Cartel
Office should request additional information or documentary material under the
HSR Act or the GWB, consummation of the merger could be delayed until after the
companies have substantially complied with the request.
 
     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 Consilium 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 consummate the
merger. Applied Materials does not have any obligation under the merger
agreement to: (i) dispose or cause any of its subsidiaries to dispose of any
assets; (ii) discontinue or make any changes to its operations or proposed
operations or to the operations or proposed operations of any of its
subsidiaries; or (iii) make any commitment (to any governmental body or
otherwise) regarding its future operations, or the future operations of its
subsidiaries, or the future operations of Consilium or its subsidiaries, even
though the disposition of such assets or the making of such change or commitment
might facilitate the obtaining of a required governmental authorization or might
otherwise facilitate the consummation of the merger.
 
ABSENCE OF APPRAISAL RIGHTS
 
     Under Section 262 of the DGCL, stockholders who do not vote in favor of or
consent to a merger are not entitled to appraisal rights if the stock subject to
such merger is designated as a national market system security on an interdealer
quotation system by the National Association of Securities Dealers, Inc. and the
consideration to be received in such merger consists of stock listed on a
national securities exchange or designated as a National Market System Security
on an interdealer quotation system by the National Association of Securities
Dealers, Inc. Because the Nasdaq National Market is designated as such a system
and the Consilium common stock and Applied Materials common stock are quoted on
the Nasdaq National Market, holders of Consilium common stock are not entitled
to appraisal rights with respect to the merger.
 
     The merger agreement provides that holders of Consilium preferred stock
may, under certain circumstances and by following certain procedures prescribed
by Section 262 of the DGCL, exercise appraisal rights and receive cash for their
shares of Consilium preferred stock. After the announcement of the merger, all
of the holders of Consilium preferred stock converted their shares of Consilium
preferred stock into shares of Consilium common stock. Consequently, no shares
of Consilium preferred stock are currently outstanding, and no stockholders of
Consilium are entitled to appraisal rights with respect to the merger.

RESALE OF APPLIED MATERIALS COMMON STOCK
 
     The Applied Materials common stock issued in connection with the merger
will be freely transferable, except that shares issued to any Consilium
stockholder who is an Affiliate of Consilium or who becomes an Affiliate of
Applied Materials are subject to certain restrictions on resale. An Affiliate is
defined generally as including, without limitation, directors, certain executive
officers and certain other persons who control a company. Certain stockholders
of Consilium who may be deemed to be Affiliates have executed agreements that
prohibit the sale, transfer or other disposition of Applied Materials common
stock received by such stockholders in the merger, except under certain
circumstances, in order to comply with the requirements of certain federal
securities laws and certain pooling of interests requirements. See "Approval of
the Merger and Related Transactions -- Affiliate Agreements." Certain
stockholders have also delivered to Applied Materials certificates certifying
that such stockholders have no present intention to dispose of certain of the
shares of Applied Materials common stock to be received by such stockholders in
the merger in order to comply with the requirements of certain U.S. federal tax
laws. See "Approval of the Merger and Related Transactions -- Certain Federal
Income Tax Consequences."

                              THE MERGER AGREEMENT
 
GENERAL
 
     The following is a summary of the material provisions of the merger
agreement, a copy of which is attached as Appendix A to this Proxy
Statement/Prospectus and is incorporated herein by reference. However, the
following is not a complete statement of all provisions of the merger agreement
and related agreements. Statements made in this Proxy Statement/Prospectus with
respect to the terms of the merger agreement and such related agreements are
qualified in their respective entireties by reference to the more detailed
information set forth in the merger agreement and such related agreements.
 
     The merger agreement provides for the merger of a wholly owned subsidiary
of Applied Materials with and into Consilium. As a result of the merger, Applied
Materials' subsidiary will cease to exist, Consilium will become a wholly owned
subsidiary of Applied Materials and the former stockholders of Consilium will
become stockholders of Applied Materials. Consilium will continue as the
surviving corporation of the merger (the "Surviving Corporation"). The merger
will become effective upon the filing of a Certificate of Merger with the
Delaware Secretary of State or at such later time as may be specified in the
Certificate of Merger. Such filing is anticipated to take place as soon as
practicable after the adoption and approval of the merger agreement and approval
of the merger by the Consilium stockholders and after expiration or termination
of the waiting period under the HSR Act, subject to the satisfaction or waiver
of the other conditions to the merger. It is currently anticipated that the
merger will be consummated, and the effective time of the merger will occur,
shortly after the Consilium special meeting. There can be no assurance, however,
that the conditions to the merger will be satisfied by such date, or at all, or
that the merger agreement will not be terminated. See "-- Conditions to the
Merger" and "Approval of the Merger and Related Transactions -- Regulatory
Matters."
 
MERGER CONSIDERATION
 
CONSILIUM COMMON STOCK
 
     Subject to the provisions contained in the merger agreement relating to the
payment of cash in lieu of fractional shares, at the effective time of the
merger, each share of Consilium common stock then outstanding (except for any
such shares held by Consilium as treasury stock and any shares held by Applied
Materials or any subsidiary of Applied Materials or Consilium) will be converted
into the right to receive between 0.182 and 0.165 of a share of Applied
Materials common stock. The exact fraction of a share of Applied Materials
common stock that each share of Consilium common stock will be converted into is
called the "Exchange Ratio." The Exchange Ratio is equal to $5.50 divided by the
average of the closing sale price of one share of Applied Materials common stock
as reported on the Nasdaq National Market for each of the twenty consecutive
trading days up to and including the second trading immediately preceding the
date of the Consilium special meeting of stockholders to approve the merger
agreement and the merger; provided, however, that if such average stock price of
Applied Materials common stock is equal to or less than $30.25, the Exchange
Ratio will be 0.182, and if such average stock price is equal to or greater than
$33.43, the
 
                                       42
<PAGE>   49
 
Exchange Ratio shall be 0.165. The table below shows the Exchange Ratio at
different average stock prices for Applied Materials common stock:

</TABLE>
 
     Applied Materials agreed to the Exchange Ratio based upon the assumption
that no more than 12,798,447 shares of Consilium common stock would be
outstanding immediately prior to the effective time of the merger (assuming for
purposes of calculating such number of shares of Consilium common stock that (i)
all shares of Consilium preferred stock were converted into Consilium common
stock prior to the effective time of the merger; (ii) all Consilium stock
options and warrants were exercised prior to the effective time of the merger;
and (iii) shares of Consilium common stock had been issued prior to the
effective time of the merger under Consilium's Employee Stock Purchase Plan
("ESPP")). The merger agreement provides that if the "Fully-Diluted Number of
Shares" exceeds 12,798,447, the Exchange Ratio shall be equal to the product of:
(1) the number that would have constituted the Exchange Ratio if the Exchange
Ratio were calculated in the manner described in the preceding paragraph;
multiplied by (2) a fraction, the numerator of which shall be 12,798,447, and
the denominator of which shall be the Fully Diluted Number of Shares. The merger
agreement defines "Fully-Diluted Number of Shares" as the sum of: (A) the number
of shares of Consilium common stock outstanding immediately prior to the
effective time of the merger (assuming that shares of Consilium common stock had
been issued pursuant to the ESPP in the manner described in Section 5.4(d) of
the merger agreement); (B) the number of shares of Consilium common stock
issuable upon the conversion of any shares of Consilium preferred stock
outstanding immediately prior to the effective time of the merger; (C) the
number of shares of Consilium common stock issuable upon the exercise of any
Consilium stock options outstanding immediately prior to the effective time of
the merger (whether or not such Consilium stock options are then exercisable);
and (D) the number of shares of Consilium common stock issuable upon the
exercise of any Consilium warrants outstanding immediately prior to the
effective time of the merger (whether or not such Consilium warrants are then
exercisable). As of October 22, 1998 the "Fully-Diluted Number of Shares" was
equal to 12,434,894.
 
CONSILIUM PREFERRED STOCK
 
     All holders of Consilium preferred stock have converted their Preferred
Stock into Consilium common stock. The shares of Consilium common stock received
by the prior holders of Consilium preferred stock will be converted into the
right to receive shares of Applied Materials common stock in the manner
described above.
 
CONSILIUM WARRANTS
 
     Certain warrants to purchase shares of Consilium common stock will, by
their terms, be converted into Consilium common stock prior to the effective
time of the merger. The shares of Consilium common stock received by the prior
holders of such Consilium warrants will be converted into the right to receive
shares of Applied Materials common stock in the manner described above. Certain
other warrants to purchase Consilium common stock, which are currently
exercisable at a price of $6.33 per share, may be exercised at
 
                                       43
<PAGE>   50
 
any time prior to August 18, 2002. If such warrants are exercised prior to the
effective time of the merger, the holders thereof will receive Consilium common
stock (which will be converted into the right to receive shares of Applied
Materials common stock in the manner described above). If such warrants are not
exercised prior to the effective time of the merger, they will be converted into
and become rights with respect to Applied Materials common stock, and Applied
Materials shall assume each such warrant in accordance with the terms (as in
effect as of the date of this Agreement) of the warrant agreement by which it is
evidenced. From and after the effective time of the merger, (i) each such
warrant assumed by Applied Materials may be exercised solely for shares of
Applied Materials common stock, (ii) the number of shares of Applied Materials
common stock subject to each such warrant shall be equal to the number of shares
of Consilium common stock subject to such warrant immediately prior to the
effective time of the merger multiplied by the Exchange Ratio, rounding down to
the nearest whole share (with the cash value of any fraction of a share of
Applied Materials common stock, less the exercise price applicable to such
fraction of a share, being payable for the portion of such assumed warrant
relating to any such fraction of a share of Applied Materials common stock),
(iii) the per share exercise price under each such warrant shall be adjusted by
dividing the per share exercise price under such warrant by the Exchange Ratio
and rounding up to the nearest cent and (iv) any restriction on the exercise of
any such warrant shall continue in full force and effect and the term,
exercisability, vesting schedule and other provisions of such warrant shall
otherwise remain unchanged; provided, however, that each warrant assumed by
Applied Materials shall, in accordance with its terms, be subject to further
adjustment as appropriate to reflect any stock split, division or subdivision of
shares, stock dividend, reverse stock split, consolidation of shares,
reclassification, recapitalization or other similar transaction subsequent to
the effective time of the merger.
 
NO FRACTIONAL SHARES
 
     No fractional shares of Applied Materials common stock will be issued in
connection with the merger, and no certificates for any such fractional shares
will be issued. In lieu of such fractional shares, any holder of Consilium
common stock who would otherwise be entitled to receive a fraction of a share of
Applied Materials common stock (after aggregating all fractional shares of
Applied Materials common stock issuable to such holder) will, upon surrender of
such holder's stock certificate(s) representing Consilium common stock to
Applied Materials' share exchange agent (the "Exchange Agent"), 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
Applied Materials common stock as reported on the Nasdaq National Market for
each of the twenty consecutive trading days up to and including the second
trading day immediately preceding the date of the Consilium special meeting of
stockholders to approve the merger agreement and merger.
 
STOCK OPTIONS; EMPLOYEE STOCK PURCHASE PLAN
 
  Stock Options
 
     At the effective time of the merger, all rights with respect to Consilium
common stock under each Consilium stock option then outstanding shall be
converted into and become rights with respect to Applied Materials common stock,
and Applied Materials shall assume each such Consilium stock option in
accordance with the terms (as in effect as of the date of the merger agreement)
of the stock option plan under which it was issued, the stock option agreement
by which it is evidenced and any applicable Change of Control Agreement. From
and after the effective time of the merger, (i) each Consilium stock option
assumed by Applied Materials may be exercised solely for shares of Applied
Materials common stock, (ii) the number of shares of Applied Materials common
stock subject to each such Consilium stock option shall be equal to the number
of shares of Consilium common stock subject to such Consilium stock option
immediately prior to the effective time of the merger multiplied by the Exchange
Ratio, rounding down to the nearest whole share, (iii) the per share exercise
price under each such Consilium stock option shall be adjusted by dividing the
per share exercise price under such Consilium stock option by the Exchange Ratio
and rounding up to the nearest cent and (iv) any restriction on the exercise of
any such Consilium stock option shall continue in full force and effect and the
term, exercisability, vesting schedule and other provisions of such Consilium
stock option shall otherwise remain unchanged; provided, however, that each
Consilium stock option assumed by Applied
 
                                       44
<PAGE>   51
 
Materials in accordance with the merger agreement shall, in accordance with its
terms, be subject to further adjustment as appropriate to reflect any stock
split, division or subdivision of shares, stock dividend, reverse stock split,
consolidation of shares, reclassification, recapitalization or other similar
transaction subsequent to the effective time of the merger. Applied Materials
shall file with the SEC, within 7 days after the date on which the merger
becomes effective, a registration statement on Form S-8 relating to the shares
of Applied Materials common stock issuable with respect to the Consilium stock
options assumed by Applied Materials in accordance with the merger agreement. As
soon as practicable after the effective time of the merger (but in no event
later than 30 days thereafter), Applied Materials shall deliver to each holder
of a Consilium stock option an appropriate notice setting forth such holder's
rights with respect to such Consilium stock option and indicating that such
Consilium stock option shall continue in effect on the same terms and conditions
as were in effect immediately prior to the effective time of the merger (subject
to the adjustments required pursuant to the merger agreement).
 
     Notwithstanding anything to the contrary contained in the merger agreement,
in lieu of assuming outstanding Consilium stock options in accordance with the
merger agreement, Applied Materials may, at its election, substitute reasonably
equivalent stock options ("Replacement Options") for outstanding Consilium stock
options. The number of shares of Applied Materials common stock subject to
Replacement Options, as well as the per share exercise price of such Replacement
Options, shall be determined in the manner specified in the merger agreement. If
Applied Materials elects to substitute Replacement Options in lieu of assuming
outstanding Consilium stock options, Applied Materials shall take all corporate
action necessary to approve the Replacement Options described in the merger
agreement in a manner qualifying under Section 424(a) of the Code and shall
deliver an agreement evidencing such Replacement Options to each applicable
holder of a Consilium stock option within 30 days after the effective time of
the merger. Shares of Applied Materials common stock issuable pursuant to the
Replacement Options shall be registered on the Form S-8 registration statement
referred to in the merger agreement.
 
EMPLOYEE STOCK PURCHASE PLAN
 
     As of the effective time of the merger, Consilium's 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 of the merger as the last day of such
offering period and by making such other pro-rata adjustments as may be required
pursuant to the ESPP to reflect the reduced offering period but otherwise
treating such offering period as a fully effective and completed offering period
for all purposes of such Plan. Prior to the effective time of the merger,
Consilium shall take all actions that are necessary to give effect to the
transactions contemplated by the merger agreement; provided, however, that the
change in the offering period referred to in the merger agreement shall be
conditioned upon the consummation of the merger.
 
STOCK OWNERSHIP FOLLOWING THE MERGER
 
     Assuming that the maximum number of shares of Applied Materials common
stock issuable in connection with the merger, based upon the number of shares of
Applied Materials common stock issued and outstanding as of the Record Date (and
after giving effect to the maximum number of additional shares of Applied
Materials common stock that may be issued in the merger), the former holders of
Consilium common stock would hold less than one percent of Applied Materials'
total issued and outstanding shares.
 
CONVERSION OF SHARES; PROCEDURES FOR EXCHANGE OF CERTIFICATES
 
     As soon as reasonably practicable after the effective time of the merger,
the exchange agent will mail to the registered holders of Consilium common stock
(i) a letter of transmittal to accompany the Consilium stock certificates to the
exchange agent (the "Letter of Transmittal") and (ii) instructions for use of
the Letter of Transmittal in effecting the surrender of Consilium stock
certificates in exchange for certificates representing Applied Materials common
stock. Upon surrender of a Consilium 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 Applied
Materials, the holder of such Consilium
 
                                       45
<PAGE>   52
 
Stock Certificate shall be entitled to receive in exchange therefor a
certificate representing the whole number of shares of Applied Materials common
stock that such holder has the right to receive. The Consilium stock
certificates so surrendered shall be cancelled. No fractional shares of Applied
Materials common stock will be issued in connection with the merger, and no
certificates for any such fractional shares will be issued. See "-- No
Fractional Shares."
 
     If any Consilium stock certificate has been lost, stolen or destroyed,
Applied Materials may require the owner of such lost, stolen or destroyed
Consilium stock certificate to provide an appropriate affidavit and to deliver a
bond (in such sum as Applied Materials may reasonably direct) as indemnity
against any claim that may be made against the exchange agent, Applied Materials
or Consilium with respect to such Consilium stock certificate.
 
     CONSILIUM STOCKHOLDERS SHOULD NOT SURRENDER THEIR CONSILIUM STOCK
CERTIFICATES FOR EXCHANGE UNTIL THEY RECEIVE A LETTER OF TRANSMITTAL FROM THE
EXCHANGE AGENT.
 
EFFECT ON CERTIFICATES
 
     At the effective time of the merger, (i) all shares of Consilium common
stock outstanding immediately prior to the effective time of the merger will
automatically be canceled and retired and will cease to exist, and all holders
of certificates representing shares of Consilium common stock that were
outstanding immediately prior to the effective time of the merger will cease to
have any rights as stockholders of Consilium, and (ii) the stock transfer books
of Consilium will be closed with respect to all shares of Consilium common stock
outstanding immediately prior to the effective time of the merger. No further
transfer of any such shares of Consilium common stock will be made on such stock
transfer books after the effective time of the merger. If, after the effective
time of the merger, a Consilium stock certificate is presented to the exchange
agent (or to Consilium or Applied Materials), such Consilium stock certificate
will be canceled and will be exchanged as provided above under the caption
"-- Conversion of Shares; Procedure for Exchange of Certificates; No Fractional
Shares."
 
CORPORATE MATTERS
 
     As of the effective time of the merger, the certificate of incorporation of
the Surviving Corporation will be amended and restated to conform to the form of
certificate of incorporation attached to the merger agreement, and the bylaws of
the Surviving Corporation will be amended and restated to conform to the bylaws
of Merger Sub as in effect immediately prior to the effective time of the
merger. The merger agreement provides that concurrently with the effective time
of the merger, the directors and officers of Consilium will resign and the
directors and officers of the Surviving Corporation immediately after the
effective time of the merger shall be the respective individuals who are
directors and officers of Merger Sub immediately prior to the effective time of
the merger.

Period"):
 
     - Consilium shall, and shall cause the respective representatives of
       Consilium and its subsidiaries to: (i) provide Applied Materials and
       Applied Materials' representatives with reasonable access to the
       representatives, personnel and assets of Consilium and its subsidiaries

Consilium agreed (i) to consult with Applied Materials within a reasonable
period of time prior to: (A) permitting Consilium or any of its
 
                                       49
<PAGE>   56
 
subsidiaries to enter into (1) any letter of intent, memorandum of understanding
or other contract relating to Consilium's FAB300 software project, or (2)
certain other contracts described in the merger agreement, and (B) hiring any
employee at the level of manager through (but not including) vice president; and
(ii) to notify Applied Materials in writing of: (A) the discovery by Consilium
of any event, condition, fact or circumstance that occurred or existed on or
prior to the date of the merger agreement and that caused or constitutes a
material inaccuracy in any representation or warranty made by Consilium in the
merger agreement; (B) any event, condition, fact or circumstance that occurs,
arises or exists after the date of the merger agreement and that would cause or
constitute a material inaccuracy in any representation or warranty made by
Consilium in the merger agreement if (1) such representation or warranty had
been made as of the time of the occurrence, existence or discovery of such
event, condition, fact or circumstance, or (2) such event, condition, fact or
circumstance had occurred, arisen or existed on or prior to the date of the
merger agreement; (C) any material breach of any covenant or obligation of
Consilium; and (D) any event, condition, fact or circumstance that would make
the timely satisfaction of any of the conditions set forth in the merger
agreement impossible or unlikely or that has had or could reasonably be expected
to have a "Material Adverse Effect" on Consilium and its subsidiaries.
 
     An event, violation, inaccuracy, circumstance or other matter will be
deemed to have a "Material Adverse Effect" on Consilium and each of its
subsidiaries, if such event, violation, inaccuracy, circumstance or other matter
(considered together with all other matters that would constitute exceptions to
the representations and warranties set forth in the merger agreement but for the
presence of "Material Adverse Effect" or other materiality qualifications, or
any similar qualifications, in such representations and warranties) would have a
material adverse effect on: (i) the business, condition, assets, liabilities,
operations or results of operations of Consilium and its subsidiaries taken as a
whole; provided, however, that none of the following shall be deemed, in and of
itself, to have a Material Adverse Effect on Consilium and its subsidiaries for
purposes of the condition that requires Consilium's representations and
warranties to be accurate as of the closing date of the merger: (A) a change in
the market price or trading volume of the Consilium common stock, (B) a failure
by Consilium to meet any published securities analyst estimates of revenue or
earnings for any period ending or for which earnings are released on or after
October 12, 1998 and prior to the closing of the merger, (C) a failure to report
earnings results in any quarter ending on or after October 12, 1998 consistent
with Consilium's historical earnings results for its Semiconductor and
Electronics business unit in any quarter during fiscal 1997 or 1998, (D) an
event, violation, inaccuracy, circumstance or other matter that results from
conditions affecting the U.S. economy or the world economy, (E) an event,
violation, inaccuracy, circumstance or other matter that results from conditions
affecting the semiconductor industry or the semiconductor equipment industry so
long as such conditions do not affect Consilium in a disproportionate manner as
compared with companies of a similar size, (F) a delay in customer orders
arising primarily out of or resulting primarily from the announcement of the
transactions contemplated by the merger agreement; and (G) an event, violation,
inaccuracy, circumstance or other matter that results from the taking of any
action required by the merger agreement, (ii) the ability of Consilium to
consummate the merger or any of the other transactions contemplated by the
merger agreement or to perform any of its material 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
the Surviving Corporation. An event, violation, inaccuracy, circumstance or
other matter will be deemed to have a "Material Adverse Effect" on Applied
Materials if such event, violation, inaccuracy, circumstance or other matter
(considered together with all other matters that would constitute exceptions to
the representations and warranties set forth in the merger agreement but for the
presence of "Material Adverse Effect" or other materiality qualifications, or
any similar qualifications, in such representations and warranties) would have a
material adverse effect on the business, condition, assets, liabilities,
operations or results of operations of Applied Materials and its subsidiaries
taken as a whole; provided, however, that none of the following shall be deemed,
in and of itself, to have a Material Adverse Effect on Applied Materials for
purposes of the condition that requires that Applied Materials' representations
and warranties be accurate as of the closing date of the merger: (A) an event,
violation, inaccuracy, circumstance or other matter that results from conditions
affecting the U.S. economy or the world economy, (B) an event, violation,
inaccuracy, circumstance or other matter that results from the semiconductor
industry or the semiconductor equipment industry conditions that do not affect
Applied Materials in a
 
                                       50

disproportionate manner as compared with companies of a similar size, and (C) an
event, violation, inaccuracy, circumstance or other matter that results from the
taking of any action required by the merger agreement.

     The merger agreement also contains certain additional covenants of the

SPECIAL MEETING OF STOCKHOLDERS
 
     Consilium has agreed in the merger agreement (i) to take all action
necessary in accordance with all applicable legal requirements to call, give
notice of, convene and hold a special meeting of stockholders to consider, act
upon and vote upon the adoption and approval of this merger agreement and the
merger, and (ii) not to withdraw, amend or modify, or propose or resolve to
withdraw, amend or modify, in a manner adverse to Applied Materials, the
unanimous recommendation of the Consilium Board of Directors that the Consilium
stockholders vote in favor of and adopt and approve the merger agreement and
approve the merger; provided, however, that nothing in the merger agreement will
prevent the Consilium Board of Directors from withdrawing, amending or modifying
its unanimous recommendation in favor of the merger if (a) a "Superior Offer"
(as defined below) is made to Consilium and is not withdrawn, (b) neither
Consilium nor any of its representatives shall have violated certain covenants,
including the covenants not to solicit, initiate, encourage or induce the making
of an Acquisition Proposal, (c) the Consilium Board of Directors concludes in
good faith, after consultation with its outside counsel, that, in light of such
Superior Offer, the withdrawal, amendment or modification of such recommendation
is required in order for it to comply with its fiduciary obligations to
Consilium's stockholders under applicable law, (d) Consilium provides Applied
Materials at least 24 hours prior notice of any meeting of Consilium's Board of
Directors at which such Board of Directors is expected to consider such Superior
Offer, and (e) Consilium's Board of Directors does not withdraw, amend or modify
its unanimous recommendation in favor of the merger for at least 48 hours after
Consilium provides Applied Materials with the name of the person making such
Superior Offer and a copy of such Superior Offer. The merger agreement shall not
limit Consilium's obligation to call, give notice of, convene and hold the
Consilium special meeting of stockholders (regardless of whether the unanimous
recommendation of the Consilium Board of Directors shall have been withdrawn,
amended or modified).
 
     A "Superior Offer" is defined as an unsolicited, bona fide written offer
made by a third party to purchase (by means of a merger, consolidation,
amalgamation, share exchange, business combination, issuance of securities,
acquisition of securities, tender offer, exchange offer or other similar
transaction) more than 50% of the outstanding shares of Consilium common stock,
which the Board of Directors of Consilium determines, in good faith, based on
the written advice of its financial advisor, has terms more favorable to
Consilium's stockholders than the terms of the merger; provided, however, that
any such offer shall not be deemed to be a "Superior Offer" unless any financing
required to consummate the transaction contemplated by such offer is either (i)
in the possession of such third party at the time such offer is made, or (ii)
committed and likely to be obtained by such third party on a timely basis.

ADDITIONAL AGREEMENTS
 
     Pursuant to the merger agreement, Applied Materials and Consilium,
respectively, have agreed to 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 the merger agreement; however, Applied
Materials does not have any obligation under the merger agreement to: (i)
dispose or cause any of its subsidiaries to dispose of any assets, or commit to
cause Consilium or any of its subsidiaries to dispose of any assets; (ii)
discontinue or cause any of its subsidiaries to discontinue offering any
product, or commit to cause Consilium or any of its subsidiaries to discontinue
offering any product; (iii) license or otherwise make available, or cause any of
its subsidiaries to license or otherwise make available, to any third party, any
technology, software or other proprietary asset, or commit to cause Consilium or
any of its subsidiaries to license or otherwise make available to any third
party any technology, software or other proprietary asset; (iv) hold separate or
cause any of its subsidiaries to hold separate any assets or operations, or to
commit to cause Consilium or any of its subsidiaries to hold separate any assets
or operations; or (v) make or cause any of its subsidiaries to make any
commitment regarding its future operations or the future operations of Consilium
or any of its subsidiaries.
 
NON-SOLICITATION
 
     Pursuant to the merger agreement, Consilium shall not directly or
indirectly, and shall not authorize or permit any of its subsidiaries or any
representative of Consilium or any of its subsidiaries directly or indirectly
to:
 
     - solicit, initiate, encourage or induce the making, submission or
       announcement of any Acquisition Proposal or take any action that could
       reasonably be expected to lead to an Acquisition Proposal;
 
     - furnish any information regarding Consilium or any of its subsidiaries to
       any person in connection with or in response 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 similar document or any contract
       contemplating or otherwise relating to any Acquisition Transaction.
 
     Notwithstanding the foregoing restrictions, prior to the adoption and
approval of the merger agreement by Consilium's stockholders, Consilium is not
prohibited by the merger agreement from furnishing nonpublic information
regarding Consilium and its subsidiaries to, or entering into discussions with,
any person in response to a Superior Offer that is submitted by such person (and
not withdrawn) if (i) neither Consilium nor any representative of Consilium or
any of its subsidiaries shall have violated any of the restrictions described in
the preceding paragraph, (ii) the Board of Directors of Consilium concludes in
good faith, after consultation with its outside legal counsel, that the failure
to take such action would be inconsistent with the fiduciary obligations of such
Board of Directors to Consilium's stockholders under applicable law, (iii) prior
to furnishing any such nonpublic information to, or entering into discussions
with, such person, Consilium gives Applied Materials written notice of the
identity of such person and of Consilium's intention to furnish nonpublic
information to, or enter into discussions with, such person, and Consilium
receives from such person an executed confidentiality agreement containing
customary limitations on the use and disclosure of all nonpublic written and
oral information furnished to such person by or on behalf of Consilium, and (iv)
prior to furnishing any such nonpublic information to such person, Consilium
furnishes such nonpublic information to Applied Materials (to the extent such
nonpublic information has not been previously furnished by Consilium to Applied
Materials). The parties agreed that for purposes of the preceding sentence (but
for no other purpose), an offer which is conditioned on completion of due
diligence (and regarding which the Board of Directors of Consilium determines,
in good faith, based on the advice of its financial advisor, that financing is
likely to be obtained) shall be deemed to constitute a "Superior Offer" if such
offer otherwise meets the definition of "Superior Offer" set forth in the merger
agreement (other than the financing portion of such definition). Consilium
agreed that any violation of any of the restrictions set forth in the preceding
sentence by any representative of Consilium or any of its subsidiaries, whether
or not such representative is purporting to
 
                                       52
<PAGE>   59
 
act on behalf of Consilium or any of its subsidiaries, shall be deemed to
constitute a breach of the merger agreement by Consilium.
 
     Consilium also agreed to: (i) promptly advise Applied Materials orally and
in writing of any Acquisition Proposal (including the identity of the person
making or submitting such Acquisition Proposal and the terms thereof) that is
made or submitted by any person during the Pre-Closing Period; and (ii) keep
Applied Materials fully informed with respect to the status of any such
Acquisition Proposal and any modification or proposed modification thereto.
 
INDEMNIFICATION AND INSURANCE
 
     Pursuant to the merger agreement, all rights to indemnification existing in
favor of those persons who are directors and officers of Consilium as of October
12, 1998 (the "Indemnified Persons") for acts and omissions occurring prior to
the effective time of the merger, as provided in Consilium's Bylaws (as in
effect as of October 12, 1998) and as provided in the indemnification agreements
between Consilium and said Indemnified Persons (as in effect as of October 12,
1998), shall survive the merger and shall be observed by the Surviving
Corporation to the fullest extent available under Delaware law for a period of
five years from the effective time of the merger. The merger agreement also
provides that from the effective time of the merger until the fifth anniversary
of the effective time of the merger, 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 of the merger, the existing
policy of directors' and officers' liability insurance maintained by Consilium
as of October 12, 1998 (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 an annual premium for the Existing Policy (or for any substitute
policies) in excess of $168,750. In the event any future annual premium for the
Existing Policy (or any substitute policies) exceeds $168,750, 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 $168,750. According the merger agreement, if the
Surviving Corporation does not have sufficient capital to comply with its
obligations under Section 5.6, Applied Materials shall provide the Surviving
Corporation with such capital.

EXPENSES AND TERMINATION FEES
 
     Pursuant to the merger agreement, all fees and expenses incurred in
connection with the merger agreement and the transactions contemplated by the
merger agreement shall be paid by the party incurring such expenses, whether or
not the merger is consummated; provided, however, that Applied Materials and
Consilium shall share equally all fees and expenses, other than attorneys' and
accounting fees and expenses, incurred in connection with (i) the filing,
printing and mailing of this Form S-4 Registration Statement and Proxy
Statement/Prospectus and any amendments or supplements thereto and (ii) the
filing of the premerger notification and report forms relating to the merger
under the HSR Act.
 
     Consilium agreed to pay termination fees to Applied Materials in the
following instances:
 
     - If (a) the merger agreement is terminated by Applied Materials or
       Consilium pursuant to Section 8.1(d) of the merger agreement (for the
       failure of the stockholders of Consilium to approve the merger agreement
       and the merger) and at or prior to the time of such termination an
       Acquisition Proposal shall have been disclosed, announced, commenced,
       submitted or made (and shall not have been publicly, absolutely and
       unconditionally withdrawn and abandoned), or (b) the merger agreement is
       terminated by Applied Materials pursuant to Section 8.1(e) of the merger
       agreement (as a result of, among other things, the failure of Consilium's
       Board of Directors unanimously to recommend that Consilium's stockholders
       approve the merger agreement and the merger), then, in either such case,
       Consilium shall pay to Applied Materials, in cash at the time specified
       in the next sentence, a nonrefundable fee in the amount of $1,000,000
       (the "Initial Termination Fee"). (In the case of termination of the
       merger agreement by Consilium pursuant to Section 8.1(d) of the merger
       agreement, the fee referred to in the preceding sentence shall be paid by
       Consilium prior to such termination, and in the case of termination of
       the merger agreement by Applied Materials pursuant to Section 8.1(d) or
       Section 8.1(e) of the merger agreement, the fee referred to in the
       preceding sentence shall be paid by Consilium within two business days
       after such termination.); and
 
     - If, within 360 days after the payment of the Initial Termination Fee, an
       Acquisition Transaction (other than with Applied Materials or one of
       Applied Materials' Affiliates) is consummated, or Consilium enters into a
       definitive agreement with respect to an Acquisition Transaction (other
       than with Applied Materials or one of Applied Materials' Affiliates),
       Consilium shall pay to Applied Materials in cash an additional
       nonrefundable fee of $1,000,000, such payment to be made at or prior to
       the consummation of such Acquisition Transaction or the entering into of
       such definitive agreement, whichever is earlier.
 
     Notwithstanding the foregoing, Consilium shall not be required to pay the
termination fees described above to Applied Materials if (a) prior to the
applicable termination of the merger agreement, Applied Materials was in
material breach of its obligations under the merger agreement; (b) prior to the
applicable termination of the merger agreement (and promptly, and in any event,
no more than two business days, after Consilium discovers any such material
breach), Consilium shall have advised Applied Materials in writing that Applied
Materials is in material breach of its obligations under the merger agreement;
and (iii) prior to the applicable termination of the merger agreement, Applied
Materials shall not have substantially cured such material breach.
 
AMENDMENT; WAIVER
 
     The merger agreement may be amended with the approval of the respective
boards of directors of Consilium and Applied Materials at any time (whether
before or after the approval of the merger agreement and the approval of the
merger by the stockholders of Consilium); provided, however, that after any such
adoption any approval of the merger agreement and approval of the merger by
Consilium's stockholders, no amendment shall be made which by law requires
further approval of the stockholders of Consilium without the further approval
of such stockholders. The merger agreement may not be amended except by an
instrument in writing signed on behalf of each of the parties.
 
     No failure on the part of either party to exercise any power, right,
privilege or remedy under the merger agreement, and no delay on the part of
either party in exercising any power, right, privilege or remedy under
 
                                       58
<PAGE>   65
 
the merger 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 of any other
power, right, privilege or remedy.
 
     Neither party shall be deemed to have waived any claim arising out of the
merger agreement, or any power, right, privilege or remedy under the merger
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.
 
                             BUSINESS OF CONSILIUM
 
     Consilium is a leading independent supplier of enterprise-wide, integrated
MES software and services, based on its revenues. MES software tracks the five
essential elements of the manufacturing plant floor -- materials, equipment,
personnel, specifications/work instructions and facility conditions -- in real
time, correlates the data for true visibility and control of manufacturing
operations and automates direct production operations. This access to
comprehensive, up-to-date information about the production process enables
manufacturers to identify and implement manufacturing best practices in the
areas of cost, quality, service, compliance and speed. Such continuous
improvement in the area of production thus enables companies to use their
manufacturing operations for competitive advantage and to optimize performance
of the business as a whole.
 
     Consilium develops, markets and sells a software product line, WorkStream
DFS, targeted at manufacturers who produce their products in discrete lots or
batches, particularly those in the semiconductor and electronics industries. A
comprehensive range of services complement these products, including pre- and
post-implementation consulting, a customer response center and product training.
In addition, Consilium recently added by acquisition significant service
offerings in South Asia to provide automated factory system integration
capabilities to customers.
 
     Through its direct sales force, Consilium markets its WorkStream DFS
product line in North America, Europe and Asia. Consilium also markets its
products through distributors in Japan, Israel, Italy and Taiwan. To date,
software from Consilium's WorkStream DFS product line has been purchased by more
than 100 companies for 250 sites in 20 countries.
 
     Until February 1998, Consilium also developed, marketed and sold a software
product line, the FlowStream product line, targeted at regulated or complex
industries that employ batch process manufacturing such as pharmaceuticals,
medical devices and specialty chemicals. On February 19, 1998, Consilium sold
certain assets associated with the FlowStream product line and agreed not to
compete in the FlowStream Business for three years. See "-- Disposition of
FlowStream Assets."
 
DISPOSITION OF FLOWSTREAM ASSETS
 
     In February 1998, Consilium sold certain assets of its Healthcare Products
and Process Industries Group that focused on the FlowStream product line (the
"Healthcare Group"), pursuant to an asset purchase agreement dated February 19,
1998 (the "Asset Purchase Agreement") by and among Base Ten FlowStream, Inc.,
Base Ten Systems, Inc. (together, "Base Ten") and Consilium, for consideration
consisting of $1,500,000 in cash ($1,350,000 of which was paid on February 19,
1998 and $150,000 of which was subject to certain indemnification provisions
pursuant to the Asset Purchase Agreement and was paid in May 1998), 20% of all
annual revenues in excess of $3,200,000 recognized by Base Ten from the
licensing of the FlowStream product line during the 1998 and 1999 calendar
years, and assumption by Base Ten of substantially all of the Healthcare Group's
liabilities on a going-forward basis, with some specific obligations being
retained by Consilium. Pursuant to the Asset Purchase Agreement, Base Ten
purchased fixed assets with a net book value of approximately $500,000 and
Consilium's rights under certain contracts with customers and other third
parties relating to the FlowStream product line but did not purchase certain
patents used by both the Healthcare Group and the Semiconductor and Electronics
Business Group. Instead,
 
                                       59
<PAGE>   66
 
Consilium granted to Base Ten a worldwide royalty-free, non-transferable (except
if transferred with substantially all of the assets of the FlowStream business)
license, for the lives of the patents, without the right to sublicense, to the
exclusive use of such patents for developing, producing, manufacturing and
selling manufacturing execution systems limited to the field of healthcare
products (pharmaceutical, medical device and biotechnology) and chemical
industries. Additionally, Consilium agreed in the Asset Purchase Agreement to
indemnify Base Ten in the event of certain losses and expenses. In addition,
Consilium agreed not to compete in the business of developing, producing,
manufacturing and selling manufacturing execution systems under the trademark of
"FlowStream" for healthcare products (pharmaceutical, medical device and
biotechnology) and chemical industries for three years.
 
BACKGROUND
 
     The goal of applying computer automation to the manufacturing environment
is improved efficiency and lowered costs, both direct and indirect. There are
several different computer software applications that are designed for various
stages of the product life cycle, from computer-aided engineering and design to
computer-assisted production on the plant floor.
 
     Manufacturing execution systems are software applications specifically
designed to manage production operations on the plant floor. Some industries,
such as semiconductors, have long seen the benefit of using MES software and are
considered to have fully accepted MES as a critical tool for manufacturing.
Across many industries, there is a growing need for tools that can help improve
manufacturing performance, cost, quality, customer service and regulatory
pressures on manufacturers increase.
 
TYPES OF MANUFACTURING
 
     Manufacturing operations can be characterized as either discrete, batch
process, continuous process, or hybrid (combining more than one form). In
discrete manufacturing operations, such as electronics manufacturing, raw
material is processed in distinct units. Work-in-process can be tracked by lot,
work order or batch. In batch process manufacturing operations, such as
pharmaceutical manufacturing, material is converted from one form or state to
another through various processing steps and is tracked by batch, lot or mass
quantity. Material in batch process-type operations may be spread across several
conversion steps at once. In continuous process manufacturing operations, such
as oil refining, raw material is processed without interruption in a continuous
flow. Finally, some producers, such as specialty chemical companies, may require
a combination of batch process and discrete manufacturing operations to
manufacture their products.
 
     Manufacturers track and control each step of their operations based on
requirements of regulatory compliance, quality control assurance, and cost
reduction goals. Manufacturers with production processes that are hard to
consistently replicate must be able to ascertain the precise conditions under
which each product was manufactured to identify and correct process variability
or other causes of defects. Other manufacturers must be able to trace both
subassemblies or intermediate products and finished goods due to product
liability concerns or potential product recall, warranty or service obligations.
In addition, certain manufacturers must certify that their products have been
processed in accordance with regulatory or customer specifications, or other
standards. Manufacturers faced with these challenges must be able to follow raw
materials through each processing stage ("traceability") and recreate the
history of work-in-process from any processing stage ("genealogy"). The
collection of such data serves not only to answer questions about a particular
product or process after the fact, but acts also as a powerful tool to improve
manufacturing performance in real time during the production process.
 
     A manufacturing execution system such as Consilium's WorkStream DFS product
line provides the tools which discrete, lot-based manufacturers need to execute
their manufacturing plan and collect the data that will enable them to analyze
and control production. Typical discrete, lot-based industries include
semiconductor, disk drive and assembly operations in the commercial aircraft,
aerospace and defense industries. Such industries benefit from MES for different
reasons. For semiconductor companies, the visibility and control provided by MES
can enable various measurements of efficiency, such as capital equipment
utilization and quality. For aerospace manufacturers, assurance of regulatory
compliance is key, and MES provides both
 
                                       60

control mechanisms and reporting capabilities to address this. Indirect labor
usage is also a critical measurement for the aerospace and defense industries,
and MES provides the tools to both account for and reduce indirect labor usage.
 
PRODUCTS
 
     Consilium develops, markets and sells a software product line, WorkStream
DFS, targeted at manufacturers who produce their products in discrete lots or
batches, particularly those in the semiconductor and electronics industries.
Revenues from licenses of the WorkStream DFS family of products historically
have represented a substantial majority of Consilium's product revenues
(approximately 77%, 86%, 89% and 92% of Consilium's total license revenue in
fiscal 1995, 1996, 1997 and the nine months ended July 31, 1998, respectively).
 
     The WorkStream DFS product line monitors and controls the five essential
elements of manufacturing -- materials, equipment, personnel,
specifications/work instructions and facilities -- in real time, correlates the
data for true visibility and control of manufacturing operations and supports
automation. This access to comprehensive, up-to-date information about the
production process enables manufacturers to identify and implement manufacturing
best practices in the areas of cost, quality, service, compliance and speed.
Such continuous improvement in the area of production thus enables companies to
use their manufacturing operations for competitive advantage, and to optimize
performance of the business as a whole.
 
     In fiscal 1997, the average selling price for a new installation of the
WorkStream DFS product line was approximately $200,000.
 
     Consilium's WorkStream DFS product line includes WorkStream and WorkStream
Open, as well as a set of application servers and a connecting "message bus," or
network which, when used with either WorkStream or WorkStream Open, form a
WorkStream DFS system. Within WorkStream DFS, there are available more than 20
integrated software modules sharing a common database and graphical user
interface, grouped into four benefits or solutions areas: tracking; quality and
engineering management; planning and process automation. The application servers
provide capabilities primarily in the areas of automation and quality.
 
     WorkStream DFS monitors and controls discrete manufacturing operations,
where product lots or batches are kept intact throughout the production process.
WorkStream DFS also provides tools to enhance productivity in indirect labor
functions such as quality control, production planning and facilities
maintenance. Discrete manufacturers most commonly use WorkStream DFS systems to:
 
     - reduce cycle times and meet just-in-time deliveries
 
     - lower indirect labor costs
 
     - reduce scrap and rework
 
     - increase yield
 
     - increase utilization of capital equipment
 
     - improve quality
 
     - reduce regulatory compliance costs and
 
     - shorten response times to equipment breakdowns
 
     The WorkStream DFS system's modular design allows customers to license only
those functions necessary for their current business needs and to add functions
as their requirements evolve.
 
     The WorkStream application was initially developed to run on Digital
Equipment Corporation's line of VAX computers, using Digital's proprietary VMS
operating system with Oracle Corporation's CODASYL DBMS database. In 1992,
WorkStream was ported to Hewlett-Packard Company's HP 9000 computers running
under the HP-UX UNIX operating system and the Informix relational database. The
new product
 
                                       61
<PAGE>   68
 
was named WorkStream Open. The development of WorkStream Open incorporated
several technologies, including client/server architecture, X- windows terminal
access, Motif user interface standard, SQL database and POSIX compliance. In
early fiscal 1997, Consilium announced the port of WorkStream to Digital's Alpha
platform running the Open VMS operating system, providing a migration path for
VAX users to Digital's newer technology platform.
 
     The WorkStream and WorkStream Open systems' modules are integrated through
a common database, permitting all modules to obtain information simultaneously
from a single data source, and through a common user interface. The systems are
designed to allow distributed application processing in the Digital cluster mode
and in client/server mode. Users can access WorkStream or WorkStream Open
software directly via a terminal or workstation to enter data, view data,
initiate batch reports or analyses and view the results. Data also can be
entered using bar code wands or can be entered automatically by automated
equipment and work cell controllers.
 
     The WorkStream DFS servers, introduced in 1995, are object-oriented
applications and run in a UNIX-based environment. They are designed to operate
in a distributed software environment, use the Informix relational database and
connect to a message bus, using standard communication protocols to talk to
either WorkStream or WorkStream Open. WorkStream DFS servers are currently
available to run on Hewlett-Packard's HP 9000 line of computers with the HP-UX
operating system.
 
     In 1995, Consilium introduced a next-generation distributed technology
framework for its WorkStream DFS product line, as well as three new application
servers. The distributed technology framework is based on a software message
bus, which connects applications, software systems and manufacturing equipment
on a network. The WorkStream DFS application servers include a quality server
for on-line quality analysis and statistical quality control, a recipe
management server for centralized context-sensitive recipe management, and a
station controller for automation implementation. The next-generation additions
to the WorkStream DFS system extend the capabilities of the current WorkStream
and WorkStream Open products into a distributed, client/server environment. The
distributed nature of the WorkStream DFS system allows users to add new
functional modules or servers to their existing systems built around either
WorkStream or WorkStream Open, and to more easily integrate software
applications from other sources, as additional servers on the network. The
overall system is designed to utilize computer resources more efficiently and
operate more effectively as a result.
 
     Consilium is developing a Windows NT-based user interface and application
server for the WorkStream DFS product line.
 
     In early fiscal 1996, Consilium announced its intent to create a total
supply chain management solution for the semiconductor industry. Total supply
chain management is an initiative adopted by manufacturers in multiple
industries to improve the access to and flow of information between receipt of a
customer order and delivery of products. The first phase of Consilium's
two-phase supply chain management solution was completed in 1996, with the
integration of Consilium's WorkStream DFS software with Oracle Corporation's
order processing, financial and ERP systems. During 1997, Consilium completed
its two-phase supply chain management solution by integrating Consilium's
WorkStream DFS software with Paragon Management Systems, Inc., advanced planning
and scheduling software. The addition of Paragon's software to Consilium's total
supply chain management offering completed the link between real-time status
information of manufacturing capacity, product commitments and inventory status
with corporate systems such as order processing, sales management and financial
applications.

MARKETS AND CUSTOMERS
 
     Historically, software in the WorkStream DFS product line was used
primarily by semiconductor manufacturers whose products were sold directly into
the open market and by electronics systems companies that used the software
primarily to produce semiconductors for use in their own products. Systems from
the WorkStream DFS product line have also been installed by many commercial
aircraft, aerospace and defense, and electronics manufacturers for a range of
diverse applications, including electronics assembly; sheet metal fabrication;
disk drive assembly; silicon wafer fabrication; and radar and navigation systems
manufacture and assembly. Current target industries include manufacturers of
semiconductors and complex electronics such as disk drives and flat panel
displays in both Consilium's installed base and new accounts.
 
     For the nine months ended July 31, 1998, Consilium's ten largest customers
accounted for approximately 46% of total revenue. However, no customer accounted
for 10% or more of total revenue.
 
SALES
 
     Consilium markets its WorkStream DFS product line in North America, Europe
and Asia/Pacific Rim through its direct sales force. Consilium's 10 sales
offices also provide local customer support. In addition to its headquarters in
Mountain View, California, Consilium has North American sales offices in Dallas,
Texas, South Portland, Maine and Nashua, New Hampshire. European offices are
located in Munich, Germany, Newbury, Berkshire, United Kingdom, and Rueil
Malmaison, France. Offices in Asia and the Pacific Rim are located in Hsinchu
City, Taiwan, Seoul, Korea, Singapore and Tokyo, Japan. As of July 31, 1998, the
Company's direct sales force consisted of 54 employees.
 
     Consilium also markets and supports its products through other distribution
channels in Israel, Italy, Japan and Taiwan. Consilium's foreign distributors
either sublicense Consilium's products directly to end users after acquiring
copies from Consilium at a discount from list price, or act as agents and
receive a commission for initiating a license agreement between Consilium and
the end user. Since Consilium's foreign distributors are not employees of
Consilium and are not required to offer Consilium's products exclusively, there
can be no assurance that they will continue to market Consilium's products.
Also, despite Consilium's substantial dependence in the international market
upon the marketing, sales and customer support of its foreign distributors,
Consilium currently has limited control over such distributors.
 
     Revenues from foreign customers (including revenues related to Consilium's
recently divested FlowStream product line) represented 50% of the total revenues
for the nine months ended July 31, 1998, 51% of
 
                                       63
<PAGE>   70
 
total revenues in fiscal 1997, 45% of total revenues in fiscal 1996 and 34% of
total revenues in fiscal 1995. See "Management's Discussion and Analysis of
Financial Condition and Results of Operation -- Results of Operations" and Note
10 of Notes to Consolidated Financial Statements. The majority of Consilium's
revenues are denominated in U.S. dollars. Some foreign sales revenues are
denominated in foreign currencies and are subject to currency fluctuations
during the time between revenue recognition and receipt of funds. To date,
Consilium has not hedged against such foreign currency fluctuations.
 
     Risks inherent in Consilium's international sales may include longer
payment cycles, greater difficulty in accounts receivable collection, unexpected
changes in regulatory requirements, seasonality due to the slowdown in European
business activity during the summer months, and tariffs and other trade
barriers. In addition, Consilium may be unaware of the nature and scope of the
representations made to customers by its distributors.
 
     Since Consilium ships its standard products upon receipt of customer
orders, it generally has no material product backlog.
 
     As a Digital Cooperative Marketing Partner, Hewlett-Packard Independent
Software Vendor participant, and Oracle Corporation Cooperative Application
Initiative partner, Consilium participates in a variety of cooperative marketing
programs including joint appearances at trade shows, joint brochures, joint
sales seminars and joint sales calls.
 
     The sales cycle for a new installation of a WorkStream DFS system typically
ranges from nine to fifteen months from the initial identification of a
qualified potential user to the installation of the software. Sales cycles can
be extended due to the nature of the decision-making process for purchasing MES
solutions, which generally involves many individuals from many departments
within a manufacturing company.
 
     Implementation of a WorkStream DFS system, including customer training,
typically takes between four and six months. Follow-on orders for additional
modules, servers, and/or sites typically are not received until successful
implementation and validation at the initial site.
 
PRODUCT DEVELOPMENT
 
     Consilium has invested significant development resources to create, enhance
and extend the functionality of its WorkStream DFS and its recently divested
FlowStream software product lines. Research and development expenses were 26% of
total revenues for the nine months ended July 31, 1998, 30% of total revenues in
fiscal 1997, 28% of total revenues in fiscal 1996 and 28% of total revenues in
fiscal 1995.
 
     Consilium has also begun work on its next generation semiconductor offering
aimed at 300mm fully automated plants, called FAB300. Initial beta delivery is
planned for the end of 1998. No substantial revenue is expected from FAB300
until mid-to-late fiscal 1999.
 
     Consilium believes that its successful and timely introduction of new
WorkStream DFS modules and Consilium's new FAB300 line on the Windows NT
platform is important to continued market acceptance of such products.
 
     Consilium expects to continue to incur development expenses to maintain and
augment its current products in fiscal 1998. Development plans include the
creation of additional WorkStream DFS servers and the extension of availability
of its WorkStream and WorkStream Open software to additional platforms and
operating environments.
 
     Consilium capitalizes and amortizes eligible computer software development
costs in accordance with Statement of Financial Accounting Standards No. 86 (see
Note 2 of Notes to Consolidated Financial Statements). Consilium capitalized
$990,000 for the nine months ended July 31, 1998, $1,324,000 for fiscal year
1997, $886,000 for fiscal year 1996 and $1,460,000 for fiscal year 1995.
$990,000 represented 14% of total spending on research and development for the
nine months ended July 31, 1998, $1,324,000 represented 10% of total spending on
research and development in fiscal year 1997, $886,000 represented 8% of total
spending on research and development in fiscal year 1996 and $1,460,800
represented 16% of total spending on research and development in fiscal year
1995. Consilium amortized $480,000 for the nine months ended July 31, 1998,
 
                                       64
<PAGE>   71
 
$1,730,000 for fiscal year 1997, $1,725,000 for fiscal year 1996 and $1,863,000
for fiscal year 1995, of capitalized software development costs.
 
SYSTEMS INTEGRATION SERVICES
 
     Consilium offers system integration services, primarily to its Asian
customers. Consilium integrates third-party automation software with its own
proprietary software to offer a more comprehensive, pre-integrated solution.
This requires Consilium to resell or acquire such third-party software
applications. Consilium utilizes both internal and external resources to provide
systems integration services. Consilium believes that its systems integration
services offering enhances its ability to market the WorkStream DFS product
line, particularly in Asia, by offering comprehensive interface solutions to its
customers.
 
     To complement its own products and services offerings, Consilium believes
that the ability to identify and work with qualified systems integration firms,
which integrate various manufacturing and other systems together, is an
important component to its success. In fiscal 1996, Consilium commenced
certification program to train and certify systems integration firms to
integrate Consilium's WorkStream DFS product line in customer implementations.
 
OTHER SERVICES AND SUPPORT
 
     Consilium offers product support to its customers through comprehensive
maintenance agreements. The majority of Consilium's customers purchase and renew
product support pursuant to Consilium's standard maintenance agreement.
Maintenance, which consists of product enhancements and technical support, may
be purchased up to 30 days after the product order is delivered. Once purchased,
maintenance support is automatically renewable annually. Annual maintenance fees
are generally 15% of the list price of the modules or servers being maintained.
Product support services are provided worldwide by a combination of local office
technical support staff and Consilium's customer response center.
 
     Consilium offers a variety of training and consulting services through its
"Professional Services" organization. Training classes are regularly scheduled
at regional centers or customer locations. Consulting services cover pre-selling
analysis, installation, project management, customization and application
integration. These services are offered as consulting products with defined
deliverables in order to facilitate the customers' planning and budgeting.
Time-and-material-based services are also offered to augment Consilium's
consulting products and to meet specialized requirements.
 
     Consilium is increasing its allocation of resources to its Professional
Services organization because it believes that this function is key to
satisfying its customers' requirements for implementation and consulting
assistance. Satisfying its customers' requirements is, in turn, critical for
maintaining a positive image in the marketplace as a successful provider of MES
solutions.
 
COMPETITION
 
     Consilium believes that the primary competitive factors in the market for
MES software are size of installed base and product functionality, and that
additional factors include price/performance for its WorkStream DFS product
line, ease of use, hardware and software platform, vendor reputation, and
financial stability. Consilium believes that its products currently compete
favorably with other systems on the primary factors listed above, although it
may be at a competitive disadvantage against companies with greater financial,
marketing, services and support, and technological resources than Consilium.
Consilium also believes that the relative importance of these competitive
factors may change over time.
 
     Consilium continues to experience competition primarily from the management
information systems departments of its largest potential customers, which have
the capability to develop software internally. Consilium believes that
acquisition of MES products will increasingly shift to external vendors as
packages, services and expertise become more widely available from third
parties. Consilium continues to experience direct competition primarily in the
semiconductor industry from various competitors, including Andersen
 
                                       65
<PAGE>   72
 
Consulting, FASTech (recently acquired by Brooks Automation), ICC, International
Business Machines, Promis and SAP. Consilium anticipates increased competition
from other MES companies.
 
     ERP system vendors are beginning to compete with Consilium in the MES
market. The first such offering was released by SAP in mid-1995. These combined
MES/ERP systems only offer basic MES functionality such as equipment
maintenance, shop floor scheduling and quality control. Although basic MES
functionality may be acceptable for industries with limited tracking and control
requirements, and some potential customers may prefer a combined MES/ERP package
over buying a separate MES package, to date, the semiconductor manufacturing
industry has not moved in that direction. Consilium believes that the
development effort required for producing an MES comparable to Consilium's
WorkStream DFS product line provides a significant advantage to Consilium over
competitors.
 
PROPRIETARY RIGHTS
 
     Consilium's success and ability to compete is dependent in part upon its
proprietary technology. Consilium generally provides its products to end users
under a non-exclusive, non-transferable license that typically has a perpetual
term unless terminated for breach of the License. Under Consilium's current form
of license agreement, the licensed software may be used solely for internal
operations at specified sites. In certain instances, Consilium has granted a
customer licensed rights to any modifications made to the licensed software by
or for such a customer. Consilium protects the human readable, source code
version of its WorkStream Open products as a trade secret and an unpublished
copyrighted work.
 
     Consilium and WorkStream are registered trademarks of Consilium in the
United States and certain other foreign jurisdictions. FAB300, WorkStream DFS
and WorkStream Open are pending trademarks of Consilium.
 
     Consilium holds four patents, and also relies on a combination of trade
secret, copyright and trademark laws and license agreements to protect its
proprietary rights in its products. While Consilium intends to protect its
patent rights vigorously, there can be no assurance that any patents held by
Consilium will not be challenged, invalidated or circumvented, or that the
rights granted thereunder will provide competitive advantages to Consilium. In
connection with the sale of certain assets associated with its FlowStream
product line, Consilium granted to Base Ten a world-wide, royalty free,
non-transferable (except if transferred with substantially all of the assets of
the FlowStream Business) license for the lives of certain patents, without the
right to sublicense, to the exclusive use of such patents for developing,
producing, manufacturing and selling manufacturing execution systems limited to
the field of healthcare products (pharmaceutical, medical device and
biotechnology) and chemical industries. Consilium generally enters into
confidentiality or license agreements with employees, distributors and
customers, and limits access to and distribution of its software, documentation
and other proprietary information. Despite these precautions, there can be no
assurance that these agreements will not be breached, that Consilium will have
adequate remedies for any breach or that Consilium's competitors will not
independently develop similar or superior technology, duplicate Consilium's
product or design around patents issued to Consilium or other intellectual
property rights of Consilium. In addition, the laws of certain foreign countries
in which Consilium's products are or may be tested or sold, including various
countries in Asia, may not protect Consilium's products and intellectual
proprietary rights to as great an extent as do the laws of the United States.
 
     Consilium believes that, because of the rapid pace of technological change
in the computer software industry, patent, trade secret and copyright protection
are important to support the continued building up of knowledge, ability and
experience of Consilium's employees. This in turn supports the ability of
Consilium to provide frequent product enhancements, and to deliver quality
support services in a timely manner.
 
     There has been substantial industry litigation regarding patent and other
intellectual property rights involving technology companies. In the future,
litigation may be necessary to protect and enforce Consilium's intellectual
property rights, to defend Consilium against claimed infringement of the rights
of others and to determine the scope and validity of the proprietary rights of
others. Any such litigation could be costly and could divert management's
attention, which could have a material adverse effect on Consilium's business,
results of operations or financial condition regardless of the outcome of the
litigation. In addition, third parties
 
                                       66
<PAGE>   73
 
making claims against Consilium with respect to intellectual property
infringement may be able to obtain injunctive or other equitable relief that
could effectively block Consilium's ability to sell its products in the United
States and abroad, and could result in an award of substantial damages. In the
event of a claim of infringement, Consilium and its customers may be required to
obtain one or more licenses from third parties. There can be no assurance that
Consilium or its customers could obtain necessary licenses from third parties at
a reasonable cost or at all.
 
     Certain technology used by Consilium's products is licensed from third
parties, generally on a non-exclusive basis. Consilium believes that there are
alternative sources for each of the material components of technology licensed
by Consilium from third parties. However, the termination of any of such
licenses, or the failure of the third party licensors to adequately maintain or
update their products, could result in a delay in Consilium's ability to deliver
certain of its products while it seeks to implement technology offered by
alternative sources. While it may be necessary or desirable in the future to
obtain other licenses relating to one or more of Consilium's products or
relating to current or future technologies, there can be no assurance that
Consilium will be able to do so on commercially reasonable terms or at all.
 
EMPLOYEES
 
     As of July 31, 1998, Consilium had a total of 190 full-time employees,
including 54 in sales, marketing and related activities, 52 in product
development and maintenance, 70 in services and support, and 14 in management,
administration and finance. Consilium has 40 employees (excluding sales) in
systems integration services in Taiwan and Singapore. Consilium also regularly
utilizes a significant number of contract personnel, primarily to assist with
software development and to staff Consilium's internal computer information
services department. At July 31, 1998, Consilium utilized approximately 78
contracted personnel. None of Consilium's employees is represented by a labor
union. Consilium has experienced no work stoppages and believes that employee
relations are good.
 
     Competition in the recruitment of personnel in the computer software
industry is intense. Consilium believes that its future success will depend in
part on its continued ability to hire and retain qualified sales, customer
support, technical and management employees and consultants.
 
                            PROPERTIES OF CONSILIUM
 
     Consilium's principal administrative, marketing and product development and
support facilities are located in a building totaling 39,500 square feet in
Mountain View, California. Consilium believes that its current facilities are
adequate for its current needs and that suitable additional space will be
available as required. See Note 6 of Notes to Consolidated Financial Statements
for information regarding Consilium's obligations under its facilities leases.
 
                     LEGAL PROCEEDINGS INVOLVING CONSILIUM
 
     In the ordinary course of business, Consilium may be involved in legal
proceedings. As of the date hereof, there are no material legal proceedings in
which Consilium is involved or litigation pending against Consilium.

OVERVIEW
 
     In fiscal 1996, Consilium began offering systems integration services to
the semiconductor manufacturing industry. In an effort to grow its systems
integration business, in July 1996, Consilium acquired the Taiwan operations of
Systematic Designs International, Inc., a privately-held Washington corporation
("SDI") specializing in the development of factory automation products and
systems integration services for the semiconductor industry. Consilium purchased
two existing semiconductor plant automation contracts, certain tangible and
intangible assets and assumed certain liabilities of SDI. The acquisition was
accounted for as a purchase and, accordingly, the results of the Taiwan
operations of SDI since the date of acquisition have been recorded in
Consilium's consolidated financial statements. See "-- Liquidity and Capital
Resources" and Note 3 of Notes to Consolidated Financial Statements.
 
     In August 1997, Consilium again expanded its systems integration business
by acquiring certain assets of Fast Associates Pte Ltd., a Singapore corporation
specializing in semiconductor manufacturing automation with operations both in
Singapore and Taiwan ("FAST"). Consilium purchased two existing semiconductor
factory automation contracts, certain tangible and intangible assets and assumed
certain liabilities of FAST. The acquisition was accounted for as a purchase
and, accordingly, the results of FAST from the date of acquisition forward have
been recorded in Consilium's consolidated financial statements. See
"-- Liquidity and Capital Resources" and Note 3 of Notes to Consolidated
Financial Statements.
 
     In February 1998, Consilium sold certain assets associated with its
FlowStream product line to Base Ten and agreed not to compete in the FlowStream
Business for three years. See "-- Business Disposition of FlowStream Assets" and
"-- Liquidity and Capital Resources."

REVENUES
 
     Total revenues for the fiscal year ended October 31, 1997 increased 7% to
$40,635,000, compared to fiscal year 1996 total revenues of $38,147,000. The
increase in fiscal 1997 was primarily due to higher services
 
                                       69
<PAGE>   76
 
revenues associated with Consilium's new systems integration services business
in the semiconductor and electronics industries, partially offset by lower
levels of product and development revenues from Consilium's WorkStream DFS and
FlowStream product lines.
 
     Total revenues by product line for the fiscal years ended October 31, 1996
and 1997 were as follows:

     Revenues attributable to the WorkStream DFS product line increased 13% to
$35,456,000 in fiscal 1997 compared with $31,300,000 in fiscal 1996. The
increase in fiscal 1997 was due primarily to higher services revenues associated
with Consilium's new systems integration services business in the semiconductor
and electronics industries, partially offset by a lower level of product
revenues as a result of the overall slowdown in capital spending in the
semiconductor and electronics industries during the fiscal year. Revenues
attributable to the FlowStream product line decreased 24% to $5,179,000 in
fiscal 1997 compared with $6,847,000 in fiscal 1996. The year over year decrease
was due primarily to fluctuations in the timing of new orders for FlowStream
product from the healthcare product and process industries.
 
     Total revenues by geographic region for the fiscal years ended October 31,
1996 and 1997 were as follows:

Percentage of total revenues................................        16%           20%
</TABLE>
 
     The decrease in sales to North America in fiscal 1997 was due primarily to
lower product license sales in the North America region as a result of the
continuing overall weakness in the semiconductor and electronics industries. The
increase in sales to Asia/Pacific in fiscal 1997 was due primarily to an
increase in demand in the semiconductor and electronics industries for
Consilium's new systems integration services, partially offset by a decrease in
demand for Consilium's WorkStream DFS products as a result of the slowdown in
the building of new semiconductor fabrications, as well as currency fluctuations
in Asia. The increase in sales to Europe in fiscal 1997 was due primarily to
higher maintenance revenues associated with a larger installed base for
Consilium's WorkStream DFS product line.
 
     International sales accounted for 52% of total revenues in fiscal 1997 and
45% of total revenues in fiscal 1996. The increase in international sales was
attributable primarily to an increase in services revenues associated with
Consilium's new systems integration business in the Asia/Pacific region.
 
     No customer accounted for more than 10% of total revenues during the fiscal
years ended October 31, 1997 and 1996.

Product Revenues
 
     Total product revenues decreased 26% to $14,181,000 in fiscal 1997 compared
with $19,073,000 in fiscal 1996. Product revenues attributable to products in
Consilium's WorkStream DFS product line decreased 24% to $12,572,000 in fiscal
1997 compared with $16,439,000 in fiscal 1996. The fiscal 1997 decrease was due
primarily to the overall slowdown in capital spending in the semiconductor and
electronics industries and currency fluctuation issues in Asia. Product revenues
attributable to the FlowStream product line in fiscal 1997 were $1,609,000, a
decrease of 39% from revenues of $2,634,000 in fiscal 1996. The decrease in
fiscal 1997 was due to continued lower than expected market acceptance of
Consilium's FlowStream product and fluctuations in the timing of new orders for
FlowStream software from the healthcare products and process industries.
 
Services Revenues
 
     Services revenues in fiscal 1997 were $25,940,000, an increase of 50% over
$17,268,000 in fiscal 1996. Services revenues are derived primarily from
software maintenance fees, systems integration services, resident and
application consulting services and customer training. The fiscal year 1997
increase in services revenues was primarily a result of higher services revenues
associated with Consilium's new systems integration business and higher
maintenance revenue associated with a larger installed base of Consilium's
WorkStream DFS product line. Consilium believes services revenues may be subject
to fluctuations primarily due to the international currency issues, the timing
of new contracts and the completion of existing projects.
 
Development Revenues
 
     Development revenues decreased 72% in fiscal 1997 to $514,000 from
$1,806,000 in fiscal 1996. Development revenues include work associated with
porting agreements and development contract work for third parties. Under these
contracts and agreements, Consilium earns development and porting revenues, with
participating third parties having the right to license and use the software,
often sooner than otherwise would have occurred. Development revenues can vary
significantly from period to period, depending upon the number of contracts that
have been entered into and the state of completion of such projects. The fiscal
1997 decrease was due primarily to the combination of the reduction in the
number of funded development projects and completion of most existing funded
development projects during the year. Based on current internal development
resource allocations and projects planned, Consilium expects that development
revenues in fiscal 1998 will continue to decrease, although Consilium may take
on additional development projects in the future if business and strategic
objectives of Consilium are met by such projects.
 
COST OF REVENUES
 
Cost of Product Revenues
 
     Cost of product revenues includes amortization of capitalized software
development costs, royalties and purchased software that is resold to the end
customer, typically along with Consilium's own software. Depending on the mix of
sales of proprietary software (and the variance in associated third party
royalties) and additional third party software relating to specific orders, the
associated costs of product revenue can vary significantly. Cost of product
revenues decreased 27% to $3,245,000 in fiscal 1997, from $4,461,000 in fiscal
1996. The absolute dollar decrease in costs of product revenues in fiscal 1997
was due primarily to lower product license sales and lower third party software
product costs. Product costs as a percent of product revenues were 23% for both
fiscal years 1997 and 1996.
 
Cost of Services Revenues
 
     Cost of services revenues includes direct labor and third party
subcontractor costs for the systems integration services business unit, customer
response center, resident and application consulting services and training
groups within Consilium. Cost of services revenues increased 108% to $15,449,000
in fiscal 1997, compared with $7,437,000 in fiscal 1996. The increase in
absolute dollars of cost of services revenues was due
 
                                       71
<PAGE>   78
 
primarily to the hiring of additional services personnel, both permanent and
subcontracted, to add to Consilium's ability to support the new systems
integration services business and to enhance Consilium's ability to meet
customer requirements for customer support and consulting services. Cost of
services revenues was 60% of total services revenues in fiscal 1997, compared
with 43% in fiscal 1996. The increase in cost of services as a percentage of
services revenues from fiscal 1997 to fiscal 1996 was due primarily to high
costs in establishing Consilium's new systems integration services business in
fiscal 1997, including hiring of additional services personnel in the
acquisitions of SDI and FAST.
 
Cost of Development Revenues
 
     Cost of development revenues includes direct labor costs associated with
development contracts and porting projects as well as third party consulting
expenses. Cost of development revenues decreased 71% to $369,000 in fiscal 1997,
compared with $1,263,000 in fiscal 1996 primarily due to lower development
revenues recorded in fiscal 1997. The decrease in absolute dollars was primarily
a result of the completion of most of the existing funded development projects
during the year. Cost of development revenues was 72% of total development
revenues in fiscal 1997, compared with 70% in fiscal 1996. Cost of development
revenues as a percentage of total development revenues can vary from year to
year depending on the nature of the development projects in process during each
year.
 
GROSS MARGIN
 
     Consilium believes gross margin as a percentage of total revenue may
fluctuate in the future due to the mix of sales of third party products versus
internally developed products, the mix and levels of product license revenues
versus service revenues and the costs associated with each development project.
 
OPERATING EXPENSES
 
Research and Development Expenses
 
     Research and development expenses include costs associated with the
development of new products and the costs of enhancing and maintaining existing
products. Research and development expenses represented 30% of total revenues in
fiscal year 1997 and 28% of total revenues in fiscal 1996. The increase in the
percentage of research and development expenses as a percentage of total
revenues in fiscal 1997 was due to a higher level of overall research and
development activity. These expenses increased to $12,165,000 in fiscal 1997,
compared with $10,847,000 in fiscal 1996. The increase in absolute dollars was
due to the hiring of additional local and offshore subcontractors during fiscal
1997 to add computing platform options and functional enhancements to
Consilium's products.
 
     Consilium expects that research and development expenses will decrease in
absolute dollars in the future as it plans to move part of its software
development group to India by subcontracting with HCL Infosystems. Consilium
expects that research and development expenses as a percentage of total revenues
will fluctuate depending on future revenue levels.
 
     Software development expenditures of $1,324,000 in fiscal 1997 and $886,000
in fiscal 1996 were capitalized under SFAS No. 86. $1,324,000 represented
approximately 10% of total research and development expenditures in fiscal 1997
and $886,000 represented approximately 8% of total research and development
expenditures in fiscal 1996. The increase was due to an increase in the absolute
dollar amount of software costs capitalized during fiscal 1997.
 
Selling and Marketing Expenses
 
     Selling and marketing expenses consist primarily of salaries and
commissions of sales and marketing personnel, advertising and promotion
expenses, and sales support costs. Selling and marketing expenses represented
34% of total revenues in both fiscal years 1997 and 1996. Selling and marketing
expenses were $13,739,000 in fiscal 1997, compared with $13,039,000 in fiscal
1996. The increase in absolute dollars in fiscal 1997 was due primarily to an
overall increase in headcount and related travel expenses.
 
                                       72
<PAGE>   79
 
     Consilium believes that selling and marketing expenses will decrease in
absolute dollars in the future as Consilium focuses on controlling operating
expenses relative to revenues and returning Consilium to profitability and
growth. Consilium expects that selling and marketing expenses as a percentage of
total revenues will fluctuate depending on future revenue levels.
 
General and Administrative Expenses
 
     General and administrative expenses include the costs of the finance, legal
and administrative operations of Consilium and represented 10% of total revenues
for both fiscal years 1997 and 1996. General and administrative expenses were
$3,993,000 in fiscal 1997, compared with $3,929,000 in fiscal 1996. The increase
in absolute dollars in fiscal 1997 was due primarily to an increase in insurance
and legal fees, partially offset by slight decreases in salaries and facilities
expenses.
 
     Consilium believes that general and administrative expenses will decrease
in absolute dollars in the future as Consilium focuses on controlling operating
expenses relative to revenues and returning Consilium to profitability and
growth. Consilium expects that general and administrative expenses as a
percentage of total revenues will fluctuate depending on future revenue levels.
 
Interest Income and Expense
 
     For fiscal 1997, interest income was $156,000, compared with $425,000 for
fiscal 1996. Lower invested cash balances and slightly lower interest rate
levels accounted for the decrease from fiscal 1996 to fiscal 1997. Interest
expense was $294,000 in fiscal 1997 and $81,000 in fiscal 1996. The increase in
interest expense in fiscal 1997 was due primarily to higher outstanding short
term borrowings during the year.
 
Provision for Income Taxes
 
     Consilium's income tax provision for fiscal years 1997 and 1996 principally
relates to withholding taxes on sales made in foreign jurisdictions. Consilium
has not incurred domestic income tax charges due to net losses in fiscal years
1997 and 1996. Consilium has established a valuation allowance against its
deferred tax assets and periodically reviews this allowance. At such time that
Consilium believes that is it more likely than not that the deferred tax asset
will be realized, the valuation allowance will be reduced.

REVENUES
 
     Total revenues for the fiscal year ended October 31, 1996 increased 15% to
$38,147,000, compared to fiscal 1995 total revenues of $33,125,000. The increase
in fiscal 1996 was due primarily to higher product license revenues as a result
of an increase in demand in the semiconductor and electronics industries for
Consilium's WorkStream products, higher maintenance revenues as a result of a
higher installed base of Consilium's WorkStream products and higher consulting
revenues.

     Revenues attributable to the WorkStream DFS product line increased 24% to
$31,300,000 in fiscal 1996 compared with $25,249,000 in fiscal 1995. The
increase in fiscal 1996 was due primarily to continued demand in the
semiconductor and electronics industries for Consilium's WorkStream product
line, especially in the Asia/Pacific region. Revenues attributable to the
FlowStream product line decreased 13% to $6,847,000 in fiscal 1996 compared with
$7,876,000 in fiscal 1995. The year over year decrease was due to fluctuations
in the timing and size of receipt of orders for the FlowStream product line.

- --------------------------------------------------------------------------------
 
     The decrease in sales to North America in fiscal 1996 was due primarily to
lower product license sales in the North America region. The increase in sales
to Asia/Pacific in fiscal 1996 was due primarily to an increase in demand in the
semiconductor and electronics industries for Consilium's WorkStream DFS products
in the Asia/Pacific region.
 
     International sales accounted for 45% and 34% of total revenues in fiscal
1996 and 1995, respectively. Increased international sales were attributable
primarily to the higher level of sales in Consilium's WorkStream DFS product
line in the Asia/Pacific region.
 
     No customer accounted for more than 10% of total revenues during the fiscal
years ended October 31, 1996 and 1995.
 
Product Revenues
 
     Product revenues increased 18% to $19,073,000 in fiscal 1996 compared with
$16,115,000 in fiscal 1995. The fiscal 1996 increase was due primarily to higher
levels of sales in Consilium's WorkStream DFS product line in the Asia/Pacific
region. In fiscal 1996, Consilium recognized $4.0 million of product license
revenues associated with two significant systems integration projects.
 
     Product revenues attributable to products in Consilium's WorkStream DFS
product line increased 32% to $16,439,000 in fiscal 1996 compared with
$12,436,000 in fiscal 1995. The fiscal 1996 increase was due primarily to an
increase in demand in the semiconductor and electronics industries for
Consilium's WorkStream Open applications and related third party products in the
Asia/Pacific region.
 
     Product revenues attributable to the FlowStream product line in fiscal 1996
were $2,634,000, a decrease of 28% from revenues of $3,679,000 in fiscal 1995.
The decrease in fiscal 1996 from fiscal 1995 was due to fluctuations in the size
and timing of orders for FlowStream software from the healthcare products and
process industries.

Services Revenues
 
     Services revenues in fiscal 1996 were $17,268,000, an increase of 8% over
$15,979,000 in fiscal 1995. Services revenues are primarily derived from
software maintenance fees, specialized programming services, resident and
application consulting services and customer training. The increase in services
revenues in fiscal 1996 was due primarily to higher maintenance revenues as a
result of a higher installed base of Consilium's WorkStream DFS product line and
to an increase in revenues from consulting services.
 
Development Revenues
 
     Development revenues increased 75% in fiscal 1996 to $1,806,000 from
$1,031,000 in fiscal 1995. Development revenues include work associated with
porting agreements and development contract work for third parties. Under these
contracts and agreements, Consilium earns development and porting revenues, with
participating third parties having the right to license and use the software,
often sooner than otherwise would have occurred. Development revenues can vary
significantly from period to period, depending upon the number of contracts
which have been entered into and the state of completion of such projects. The
fiscal 1996 increase was due primarily to revenues generated by new funded
development projects, partially offset by the completion of existing projects.
 
COST OF REVENUES
 
Cost of Product Revenues
 
     Cost of product revenues includes amortization of capitalized software
development costs, royalties, and purchased software that is resold to the
end-customer, typically along with Consilium's own software. Depending on the
mix of sales of proprietary software (and the variance in associated third party
royalties) and additional third party software relating to specific orders, the
associated costs of product revenue can vary significantly. Cost of product
revenues increased 48% to $4,461,000 in fiscal 1996, from $3,022,000 in fiscal
1995. Product costs as a percent of product revenue were 23% in fiscal 1996 and
19% in fiscal 1995. The increase in cost of product revenues in fiscal 1996 was
due to higher product revenues recorded during the year and higher third party
product costs associated with two systems integration projects.
 
Cost of Services Revenues
 
     Costs of services revenues includes expenses for the customer response
center, resident and application consulting services, specialized programming
services, and training groups within Consilium. Cost of services revenues was
43% of total services revenues in fiscal 1996, compared with 31% in fiscal 1995.
The increase in cost of services as a percentage of services revenues from
fiscal 1996 to fiscal 1995 was due to the increased usage of third party
consultants and the hiring of additional services personnel. Cost of services
revenues increased 50% from $7,437,000 in fiscal 1996, compared with $4,967,000
in fiscal 1995. The absolute dollar increase in cost of services from fiscal
1996 to fiscal 1995 was due primarily to the hiring of additional services
personnel, both permanent and sub-contracted, to enhance Consilium's ability to
meet customer requirements for maintenance, support and consulting services. In
late fiscal 1996, Consilium commenced a new systems integration services
business relating to its WorkStream DFS product line. Cost of services revenues
associated with systems integration services in fiscal 1996 was minimal.
 
Cost of Development Revenues
 
     Cost of development revenues includes direct labor costs associated with
development contracts and porting projects as well as third party consulting
expenses. Cost of development revenues was 70% of total development revenues in
fiscal 1996, compared with 61% in fiscal 1995. The increase in cost of
development as a percentage of development revenues in fiscal 1996 was due
primarily to relatively high development costs associated with two development
projects during the fiscal year. Development costs increased 100% from $632,000
in fiscal 1995 to $1,263,000 in fiscal 1996 as a result of higher development
revenues recorded in fiscal 1996 and higher costs associated with two
development projects in fiscal 1996.

<PAGE>   83
 
GROSS MARGIN
 
     Consilium believes gross margin as a percentage of total revenue may
fluctuate in the future due to the mix of sales of third party products versus
internally developed products, the mix and levels of product license revenues
versus service revenues and the costs associated with each development project.
 
OPERATING EXPENSES
 
Research and Development Expenses
 
     Research and development expenses includes costs associated with the
development of new products and the costs of enhancing and maintaining existing
products. Research and development expenses represented 28% of total revenues in
fiscal years 1996 and 1995. These expenses increased to $10,847,000 in fiscal
1996 compared with $9,246,000 in fiscal 1995. The absolute dollars increase in
research and development expense from fiscal 1995 to fiscal 1996 was due to a
higher level of overall research and development activity primarily to add
computing platform options and functional enhancements for Consilium's products.
 
     Software development expenditures of $886,000 and $1,460,000 were
capitalized under SFAS No. 86 in fiscal 1996 and 1995, respectively. The amounts
capitalized represented approximately 8% and 14%, respectively, of total
research and development expenditures during such periods. The percentage
decrease was due to a decline in the absolute dollar amount of software costs
capitalized during these periods coupled with a higher level of overall research
and development expenditures.
 
Selling and Marketing Expenses
 
     Selling and marketing expenses consist primarily of salaries and
commissions of sales and marketing personnel, advertising and promotion
expenses, and customer service and support costs. Selling and marketing expenses
represented 34% of total revenues in fiscal 1996, compared with 37% in fiscal
1995. Selling and marketing expenses increased to $13,039,000 in fiscal 1996
from $12,264,000 in fiscal 1995. The increase in absolute dollars in fiscal 1996
was due primarily to an increase in commission expenses, related travel
expenses, advertising and promotion expenses. The decrease in sales and
marketing expense as a percentage of total revenues in fiscal 1996 was due to
the increase in revenues while holding headcount and other costs relatively
stable.
 
General and Administrative Expenses
 
     General and administrative expenses include the costs of the finance, legal
and administrative operations of Consilium and represented 10% of total revenues
for fiscal year 1996, and 9% of total revenues for fiscal year 1995. General and
administrative expenses increased to $3,929,000 in fiscal 1996 from $3,119,000
in fiscal 1995. The increase from fiscal 1995 to fiscal 1996 was due to an
increase in headcount, an increase in legal and accounting related expenses
primarily related to the costs of the fiscal year 1995 restatement which
occurred during fiscal 1996 and costs associated with a relocation of
Consilium's headquarters in February 1996.
 
Restructuring Charge
 
     During the third quarter of fiscal 1994, Consilium announced a worldwide
consolidation of its operations and recorded a restructuring charge of
$1,407,000. The consolidation primarily affected several field offices. Major
cost components associated with the restructuring were severance pay amounts for
terminated employees, lease and rental costs associated with the consolidation
of sales offices and the consolidation of operations at Consilium's
headquarters. The balance was comprised of fixed asset write-offs in the offices
affected, as well as travel and legal fees. The consolidation was designed to
improve efficiencies and bring operational expenses in line with revenues.
During the third quarter of fiscal 1995, Consilium reevaluated the status of its
restructuring activities in light of results of operations that had improved
substantially since the commencement of the restructuring. As a result of that
reevaluation, Consilium decided to discontinue subsequent restructuring
activities and reversed the remaining restructuring reserve of $211,000 in
fiscal 1995.
 
                                       77
<PAGE>   84
 
Interest Income and Expense
 
     For fiscal 1996, interest income was $425,000, compared with $588,000 for
fiscal 1995. Lower invested cash balances and slightly lower interest rate
levels accounted for the decrease from fiscal 1995 to fiscal 1996. Interest
expense was $81,000 in fiscal 1996 and $10,000 in fiscal 1995. The increase in
interest expense in fiscal 1996 was primarily due to interest on a $2,000,000
promissory note obtained with a bank in April 1996.
 
Provision for Income Taxes
 
     Consilium's income tax provision for fiscal years 1996 and 1995 principally
relates to withholding taxes on sales made in foreign jurisdictions. Consilium
has not incurred domestic income tax charges due to net losses in fiscal years
1996 and utilization of net operating loss carryforwards in fiscal year 1995.
Consilium has established a valuation allowance against its deferred tax assets
and periodically reviews this allowance. At such time that Consilium believes
that is it more likely than not that the deferred tax asset will be realized,
the valuation allowance will be reduced.

     Total revenues for the first nine months of fiscal 1998 decreased 21% to
$24,204,000, compared with $30,574,000 in the same period of fiscal 1997. The
decrease in total revenues was primarily due to the sale of the Health Care and
Process business unit, lower levels of WorkStream DFS(TM) product revenues,
systems integration services revenues and development revenues, partially offset
by a higher level of consulting revenues from its Semiconductor and Electronics
business unit.
 
     Total revenues by product line for the nine months ended July 31, 1997 and
1998 were as follows:

     Revenues attributable to the WorkStream DFS product line decreased 16% to
$22,206,000 for the nine months ended July 31, 1998 compared with $26,355,000
for the same period in fiscal 1997. The decrease in fiscal 1998 was primarily
due to lower WorkStream license revenue and lower systems integration services
revenues as a result of the recession in the semiconductor industry and the poor
economic conditions in Asia.

</TABLE>
 
- --------------------------------------------------------------------------------
 
     The decrease in sales to North America for the nine months ended July 31,
1998 was due to the sale of the Health Care and Process business units and lower
level of WorkStream product license and maintenance revenues in North America
region. The decrease in sales to Europe for the nine months ended July 31, 1998
was due to the sale of the Health Care and Process business unit. The
proportional decrease in sales to Asia/ Pacific for the nine months ended July
31, 1998 was primarily due to lower WorkStream license revenue and lower systems
integration services revenues in the Asia/Pacific region as a result of the
completion of existing projects, slowdown in the building of new semiconductor
fabrications, as well as currency fluctuations in Asia.
 
     International sales accounted for 50% and 52% of total revenues for the
nine months ended July 31, 1998 and 1997, respectively.
 
     No customers accounted for more than 10% of total revenues during the nine
months ended July 31, 1998 and 1997.
 
Product Revenues
 
     Product revenues for the nine months ended July 31, 1998 decreased 44% over
the same period of the previous fiscal year. The decrease was primarily due to
lower product revenue levels from Consilium's WorkStream DFS and FlowStream
product lines during the period as described below.
 
                                       80
<PAGE>   87
 
     Product revenues attributable to products in Consilium's WorkStream DFS(TM)
product line decreased 45% to $5,340,000 during the nine months ended July 31,
1998, as compared with $9,763,000 for the same period in fiscal 1997. The
decrease was primarily due to the continued slowdown in the semiconductor
industry, the poor economic conditions and currency issues in Asia and
fluctuations in timing of new orders for WorkStream products from new
semiconductor fabrications.
 
     Product revenues attributable to FlowStream for the nine months ended July
31, 1998 were $942,000, as compared $1,471,000 for the same period in fiscal
1997. The decrease was attributable to the sale of the Healthcare Products and
Process Industries Group that focused on the Flowstream product line in the
second quarter of fiscal 1998.
 
Services Revenues
 
     Services revenues for the nine months ended July 31, 1998 decreased 5% to
$17,922,000, compared with $18,826,000 for the same period of fiscal 1997.
Services revenues are primarily from annual software maintenance fees, systems
integration services relating to the WorkStream DFS(TM) product line,
specialized programming services, resident and application consulting services
and customer training. The decrease in services revenues for the nine months
ended July 31, 1998 was primarily due to the sale of the Health Care and Process
business unit, and a decrease in systems integration services revenues,
partially offset by an increase in consulting services revenues from Consilium's
WorkStream product line. Services revenues normally are subject to fluctuations
primarily due to the timing of new contracts and the completion of existing
projects.
 
Development Revenues
 
     Consilium has no development revenues for the nine months ended July 31,
1998, compared with $514,000 for the same period of fiscal 1997. Development
revenues include work associated with porting agreements and development
contract work for third parties. Under these contracts and agreements, Consilium
earns development and porting revenues, with participating third parties having
the right to license and use the software, often sooner than otherwise would
have occurred. Development revenues can vary significantly from period to
period, depending upon the number of contracts which have been entered into and
the state of completion of such projects. The decrease in development revenues
during the nine months ended July 31, 1998 was primarily due to the completion
of all funded development projects. Based on current internal development
resource allocations and projects planned, Consilium expects that Consilium will
not have any significant development revenues in fiscal 1998, although Consilium
may take on additional development projects in the future if business and
strategic objectives of Consilium are met by such projects.
 
COST AND EXPENSES
 
Cost of Product Revenues
 
     Cost of product revenues includes amortization of capitalized software
development costs, royalties, and purchased software which is resold to the end
customer, typically along with Consilium's own software. Depending on the mix of
sales of proprietary software (and the variance in associated third party
royalties) and additional third party software relating to specific orders, the
associated costs of product revenue can vary significantly. Cost of product
revenues for the nine months ended July 31, 1998 decreased 57% to $1,078,000,
compared with $2,483,000 for the same period of fiscal 1997. The absolute dollar
and percentage decrease in cost of product revenues for the nine months ended
July 31, 1998 was primarily due to lower product license sales during the
period. Product costs as a percentage of product revenues for the nine months
ended July 31, 1998 was 17%, compared with 22% for the same period of the
previous year. The decrease in cost of product revenues for the nine months
ended July 31, 1998 as a percentage of product revenues was attributable to
lower third party product costs and lower royalties associated with the product
revenues during the period.
 
                                       81
<PAGE>   88
 
Cost of Services Revenues
 
     Cost of services revenues decreased 30% to $7,980,000, compared with
$11,475,000 for the same period of the previous fiscal year. The decreases in
absolute dollars and percentage of cost of services revenues were primarily due
to lower third party systems integration consulting costs, lower systems
integration services revenues and lower FlowStream services revenues as a result
of the sale of the Health Care and Process business unit in the second quarter
of fiscal 1998, partially offset by the hiring of additional permanent services
personnel to support the systems integration services. Cost of services revenues
was 45% of total services revenues for the nine months ended July 31, 1998,
compared with 61% in the comparable period of fiscal 1997. The decrease in cost
of services revenues as a percentage of services revenues was primarily due to
an increase in systems integration projects with higher margins in fiscal 1998.
 
Cost of Development Revenues
 
     Cost of development revenues decreased to zero for the nine months ended
July 31, 1998, compared with $369,000 for the same period of the previous fiscal
year. The absolute dollar decrease in cost of development revenues for the nine
months ended July 31, 1998 was due primarily to the completion of all funded
development projects in fiscal 1997. Development costs, which may vary
significantly from project to project, include direct labor costs associated
with development contracts and porting projects as well as third party
consulting expenses.
 
GROSS MARGIN
 
     Consilium believes gross margin as a percentage of total revenue may
fluctuate in the future due to the mix of sales of third party products versus
internally developed products and the mix and levels of product license revenues
versus service revenues.
 
OPERATING EXPENSES
 
Research and Development Expenses
 
     Research and development expenses represented 26% of total revenues for the
nine months ended July 31, 1998 and 30% of total revenues for nine months ended
July 31, 1997. Research and development expenses were $6,344,000 for the nine
months ended July 31, 1998, as compared to $9,250,000 for the same period of the
previous fiscal year. The decrease in the percentage of research and development
expenses as a percentage of total revenues and the decrease in the absolute
dollar amount of research and development expenses for the nine months ended
July 31, 1998 were due primarily to lower overall research and development
activities as a result of the sale of the Healthcare Products and Process
Industries Group that focused on the FlowStream product line coupled with the
continued move of Consilium's software development group to India by
subcontracting with HCL Infosystems, and the reimbursement of research and
development expenses of $783,000 under an Advanced Technology Program (ATP)
award form the National Institute of Standards and Technology (NIST). Included
in research and development expenses are costs associated with the development
of new products and the costs of enhancing and maintaining existing products.
 
     Software development expenditures of $990,000 were capitalized for the nine
months ended July 31, 1998 and $525,000 were capitalized for the nine months
ended July 31, 1997. The amounts represent approximately 14% of total research
and development expenditures for the nine months ended July 31, 1998 and 5% of
total research and development expenditures for the nine months ended July 31,
1997. The absolute dollar and percentage increases were due to an increase in
the amount of software development costs eligible for capitalization during the
nine months ended July 31, 1998. In accordance with SFAS No. 86, the amount of
research and development expenditures capitalized in a given time period depends
upon the amount of development work performed subsequent to the establishment of
technological feasibility for a product. Accordingly, amounts capitalized may
vary from period to period.

Selling and Marketing Expenses
 
     Selling and marketing expenses represented 31% of total revenues for the
nine months ended July 31, 1998 and 33% of total revenues for the nine months
ended July 31, 1997. The decrease in sales and marketing expenses as a
percentage of total revenues during the nine months ended July 31, 1998 was due
to a lower level of sales activities, partially offset by lower total revenues
during the periods. Selling and marketing expenses were $7,474,000 for the nine
months ended July 31, 1998 and $10,094,000 for the nine months ended July 1997.
The decrease in the absolute dollar amount of selling and marketing expenses for
the nine months ended July 31, 1998, compared with the same period in fiscal
1997, was due primarily to an overall decrease in headcount and related travel
expenses as a result of the sale of the Health Care and Process business unit
and Consilium's efforts to control overall operating expenses relative to
revenues.
 
General and Administrative Expenses
 
     General and administrative expenses represented 9% of total revenues for
the nine months ended on both July 31, 1998 and 1997. General and administrative
expenses were $2,167,000 for the nine months ended July 31, 1998 and $2,809,000
for the nine months ended July 31, 1997. The decrease in absolute dollars for
the nine months ended July 31, 1998 was due primarily to an overall decrease in
headcount and Consilium's efforts to control operating expenses relative to
revenues. General and administrative expenses include the costs of the finance,
accounting and administrative operations of Consilium.
 
Interest Income and Expense
 
     Interest income was $166,000 for the nine months ended July 31, 1998,
compared to $98,000 for the same period in the previous fiscal year. Higher
invested cash balances and slightly higher interest rate levels accounted for
the increase in interest income. Interest expense was $239,000 for the nine
months ended July 31, 1998, compared to $173,000 for the same period in fiscal
1997. The increase in interest expense was primarily due to higher outstanding
short term borrowings in fiscal 1998.
 
Provision for Income Taxes
 
     The income tax provision for the nine months ended July 31, 1998 represents
taxes on earnings of certain foreign subsidiaries, which are profitable, and
withholding taxes on sales made in certain foreign jurisdictions. Consilium has
established a valuation allowance against its deferred tax asset and
periodically reviews this allowance. At such time that Consilium believes that
it is more likely than not that deferred tax asset will be realized, the
valuation allowance will be reduced.

     As of October 31, 1997, Consilium had $7,865,000 in cash and cash
equivalents, as compared with $9,094,000 in cash and cash equivalents and short
term investments at October 31, 1996. The fiscal 1997
 
                                       83
<PAGE>   90
 
decrease was due primarily to the use of cash to fund operations. During fiscal
1997, Consilium has funded its operations primarily through bank borrowings and
the proceeds from a preferred stock issuance.
 
     Net cash used for operating activities in fiscal 1997 was $3,115,000,
compared with net cash used by operating activities of $797,000 in fiscal 1996.
Net cash used for operations in fiscal 1997 primarily consisted of a net loss in
fiscal 1997 of $8,764,000, combined with an increase in accounts receivable,
partially offset by an increase in non-cash charges for depreciation and
amortization and an increase in accounts payable and deferred revenue. Higher
levels of sales on systems integration services which have relatively longer
collection cycles contributed to the increase in accounts receivable and
accounts payable.
 
     Net cash used for operating activities in fiscal 1996 was $797,000,
compared with net cash provided by operating activities of $1,702,000 in fiscal
1995. Net cash used for operations in fiscal 1996 primarily consisted of a net
loss in fiscal 1996 of $3,459,000, combined with an increase in accounts
receivable and other assets and a decrease in other liabilities and accrued
expenses, partially offset by non-cash charges for depreciation and amortization
and an increase in accounts payable. Higher levels of sales contributed to the
increase in accounts receivable and accounts payable and the purchase of SDI
(see Note 3 of Notes to Consolidated Financial Statements) accounted for the
increase in other assets. Lower accrued compensation levels contributed to the
decrease in other liabilities and accrued expenses.
 
     Net cash used for investing activities was $1,396,000 in fiscal year 1997,
$5,000,000 in fiscal year 1996 and $981,000 in fiscal year 1995. The change from
fiscal 1996 to 1997 was due to a decrease in investments in capital equipment,
and a decrease in short-term investments, partially offset by an increase in
capitalized software development costs. The change from fiscal 1995 to 1996 was
due to an increase in investments in capital equipment relating to Consilium's
relocation to its new facility, offset by a decrease in short-term investments
and a decrease in expenditures on capitalized software development costs.
 
     Net cash provided by financing activities was $4,590,000 in fiscal year
1997, $3,251,000 in fiscal year 1996 and $1,283,000 in fiscal year 1995. The
change from fiscal 1996 to 1997 was due to net proceeds from the issuance of
Convertible Series A Preferred Stock of $2,799,000 and proceeds from borrowings
on the new revolving line of credit of $3,051,000 less debt repayments of
$1,792,000. The change from fiscal 1995 to fiscal 1996 was due primarily to cash
received from a $2,000,000 promissory note obtained in fiscal 1996.
 
     As of July 31, 1998, the Company had $6,665,000 in cash and cash
equivalents, as compared with $7,865,000 in cash and cash equivalents and short
term investments at October 31, 1997. The Company used $549,000 for operating
activities during the nine months ended July 31, 1998, compared with $3,342,000
used for operating activities in the same period of the previous fiscal year.
The decrease was due primarily to a decrease in net loss, partially offset by
changes in the balances of operating assets and liabilities.
 
     Net cash used for investing activities was $182,000 during the first nine
months of fiscal 1998, as compared with $437,000 of net cash used for investing
activities for the same period in fiscal 1997. The $182,000 net cash used for
investing activities during the nine months ended July 31, 1998 represented cash
received from the sale of the Healthcare products and process industries Group
that focused on the FlowStream product line, offset by capital expenditures,
capitalized software development costs, and FAST acquisition costs and proceeds
from borrowings on the new banking facility of $2,750,000 less debt repayments
of $3,051,000.
 
     Net cash used for financing activities was $176,000 during the first nine
months of fiscal 1998, which represented proceeds from the issuance of common
stock, offset by preferred stock issuance costs.
 
     Under the asset purchase agreement to purchase certain tangible and
intangible assets from FAST, Consilium may be required to make additional annual
performance-based payments (in cash, stock, or cash and stock at Consilium's
option) over a three year period ending on August 1, 2000. Such
performance-based payments will be based upon specified percentages of systems
integration and related services net operating margin, and net product license
and maintenance revenue recognized by Consilium in certain countries in Asia for
a period of three years ending on August 1, 2000, as follows: 45% of systems
integration/services net operating margin, 10% of product license net revenue,
and 2.5% of product maintenance net revenue. Such payments may be made in cash
or Common Stock, at the option of Consilium. $1,500,000 of the performance
 
                                       84
<PAGE>   91
 
payments are guaranteed. As of July 31, 1998, $1,200,000 of these guaranteed
performance payments have been paid, $900,000 by issuance of 234,192 shares of
the Common Stock and one cash payment of $300,000. The last guaranteed
performance payment of $300,000 of cash has been paid in August 1998. FAST has
certain registration rights with respect to the Common Stock issued. Shares of
common stock issued in fiscal 1997 have been registered by Consilium in fiscal
1998.
 
     Under the original asset purchase agreement of the Taiwan operations of
SDI, Consilium was required to make additional performance-based payments in
cash or cash and stock over a two-year period ending on July 8, 1998. Subsequent
to October 31, 1997, Consilium renegotiated the major terms of the agreement
with SDI, subject to the execution of definitive agreements, such that no
additional performance-based payment would be made. On January 30, 1998,
Consilium entered into definitive agreements with SDI and SDI's principal, under
which the parties agreed to cancel the original payment provisions, and all
other continuing obligations, including but not limited to financial
obligations, arising under the original asset purchase agreement, and Consilium
agreed to issue 100,000 shares of its Common Stock to SDI within thirty days. At
the same time, Consilium and SDI entered into an amended licensing agreement
under which Consilium has the right to distribute certain SDI-owned software,
has the right to enhance certain of such software and agreed to pay royalties to
SDI based on a percentage of any actual sublicense fees for that software
received by Consilium. SDI's principal resigned from Consilium as of December
31, 1997.
 
     In April 1997, Consilium entered into a line of credit agreement under
which it can borrow up to $5,000,000, based on eligible accounts receivable (the
"Line of Credit Agreement"). The revolving Line of Credit Agreement is secured
by substantially all of Consilium's assets, bears interest at the bank's prime
rate per annum (8.5% at October 31, 1997) and expired on March 15, 1998. In
connection with the above mentioned line of credit, Consilium granted the bank
warrants to purchase 70,000 shares of the Common Stock at an exercise price of
$3.98 per share. The warrant agreement with the bank includes antidilution
provisions. However, in no event shall the number of shares issued under this
warrant exceed 100,000, nor shall the price be less than $3.00 per share. Such
warrants are fully exercisable and expire in April 2002. The bank has certain
registration rights with respect to the underlying Common Stock. On July 24,
1998, Consilium entered into a new banking arrangement and paid off the
$3,051,000 due under the above mentioned Line of Credit Agreement.
 
     Under the new banking facility, Consilium can borrow up to $6,500,000,
including a $2,750,000 three year term loan (the "Term Loan Agreement"), and an
additional line of credit (the "Revolving Facility Agreement") of up to
$3,750,000 based on eligible accounts receivable. The term loan agreement is
secured by substantially all of Consilium's assets, bears interest at 1.0% above
the prime rate per annum (9.5% at July 31, 1998) and expires on July 24, 2001.
The revolving facility agreement is secured by substantially all of Consilium's
assets, bears interest at 0.5% above the prime rate per annum (9.0% at July 31,
1998) and expires on July 24, 1999. At July 31, 1998, $2,750,000 was outstanding
under the Term Loan Agreement and no borrowings were outstanding under the
Revolving Facility Agreement. The Term Loan and Revolving Facility Agreements
require Consilium to maintain certain financial covenants. Consilium is in
compliance with all financial covenants.
 
     In August 1997, Consilium entered into the subscription agreements with
purchasers pursuant to which Consilium sold to the purchasers on August 19, 1997
an aggregate of 3,000 newly issued shares of Series A Preferred Stock of
Consilium at a price of $1,000 per share for aggregate gross proceeds to
Consilium of $3,000,000, before deducting expenses. See Note 7 of Notes to
Consolidated Financial Statements for a description of the rights, preferences
and privileges of the holders. The Series A Preferred Stock has the right to
cumulative dividends at 8% per annum through conversion. Between October 13,
1998 and October 15, 1998, the holders of the shares of Series A Preferred Stock
converted such shares into an aggregate of 1,538,457 shares of common stock. In
connection with the issuance of Series A Preferred Stock (See Note 7 of Notes to
Consolidated Financial Statements), Consilium granted the placement agents
warrants to purchase an aggregate of 150,000 shares of the Common Stock at an
exercise price of $6.33 per share. The warrants are fully exercisable and expire
in August 2002.

     In February 1998, Consilium sold certain assets of its Healthcare Products
and Process Industries Group that focused on the FlowStream product line (the
"Healthcare Group"), pursuant to an Asset Purchase Agreement dated February 19,
1998 (the "Asset Purchase Agreement") by and among Base Ten FlowStream, Inc.
(the "Buyer"), Base Ten Systems, Inc. (the "Parent" and together with the Buyer,
"Base Ten") and Consilium, for consideration consisting of $1,500,000 in cash,
20% of all annual revenues in excess of $3,200,000 recognized by Base Ten from
the licensing of the FlowStream product line during the 1998 and 1999 calendar
years, and assumption by Base Ten of substantially all of the Healthcare Group's
liabilities on a going-forward basis, with some specific obligations being
retained by Consilium. Pursuant to the Asset Purchase Agreement, Base Ten
assumed certain liabilities as of the acquisition date, purchased fixed assets
with a net book value of approximately $500,000 and assumed Consilium's rights
under certain contracts with customers and other third parties relating to the
FlowStream product line, except certain patents used within Consilium by both
the Healthcare Group and the Semiconductor and Electronics Business Group. With
regards to these patents, Consilium granted to Base Ten a worldwide
royalty-free, non-transferable (except with substantially all of the assets of
the FlowStream Business) license, for the lives of the patents, without the
right to sublicense, to the exclusive use of such patents for developing,
producing, manufacturing and selling manufacturing execution systems limited to
the field of healthcare products (pharmaceutical, medical device and
biotechnology) and chemical industries. In addition, Consilium agreed not to
compete in the business of developing, producing, manufacturing and selling
manufacturing execution systems under the trademark of "FlowStream" for
healthcare products and chemical industries for three years. Also pursuant to
the Asset Purchase Agreement, Consilium agreed to indemnify Base Ten for up to
$1,500,000 for certain representations and warranties relating to intellectual
property and up to an unlimited amount for certain post-closing covenants, any
excluded obligations (as defined in the Asset Purchase Agreement) and any tax
losses (as defined in the Asset Purchase Agreement).
 
     Management believes the existing cash and cash equivalents including cash
generated from operations combined with its borrowing capacity under the new
Term Loan and Revolving Facility Agreement will be sufficient to meet
Consilium's working capital and capital expenditure requirements for the next
twelve months.
 
RECENT ACCOUNTING PRONOUNCEMENTS
 
     In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive
Income," which establishes standards for reporting and display of comprehensive
income and its components in a full set of general purpose financial statements.
SFAS No. 130 will become effective for Consilium's fiscal year ending October
31, 1999. Consilium anticipates additional disclosure requirements on
comprehensive income upon adoption of SFAS No. 130.
 
     In June 1997, the FASB issued SFAS No. 131, "Disclosures About Segments of
an Enterprise and Related Information," which establishes standards for
disclosure of segment information. SFAS No. 131 will become effective for
Consilium's fiscal year ending October 31, 1999. Management believes the
adoption of SFAS No. 131 will have no impact on Consilium's financial
statements.
 
     Effective November 1, 1997, Consilium adopted SFAS No. 128, "Earnings Per
Share." All prior-period earnings per share data presented was restated to
conform with SFAS No. 128. SFAS No. 128 requires companies to compute net income
(loss) per share under two different methods, basic and diluted, and to disclose
the methodology used for the calculation. Basic and diluted earnings per common
share were computed by dividing net loss after deduction of preferred stock
dividends by the weighted average number of shares of common stock outstanding
during the period. Potentially dilutive securities of 2,257,462 for the three
quarters ended July 31, 1998 and 1,733,070 for the three quarters ended July 31,
1997 were not included in the computation of diluted earnings per common share
because to do so would have been antidilutive.
 
     In the first quarter of fiscal 1998, Consilium adopted the provisions of
SFAS No. 129, "Disclosure of Information about Capital Structure," which
requires companies to disclose certain information about their capital
structure. The adoption of SFAS No. 129 had no impact on Consilium's financial
statements.
 
                                       86
<PAGE>   93
 
     In April 1998, the American Institute of Certified Public Accountants
issued Statement of Position (SOP) 98-1, "Accounting for the Costs of Computer
Software Developed or Obtained for Internal Use." SOP 98-1 provides guidance
regarding the determination of whether computer software is internal-use
software, the capitalization of costs incurred for computer software developed
or obtained for internal use and accounting for the proceeds of computer
software originally developed or obtained for internal use and then subsequently
sold to the public. Consilium has not yet determined the effect, if any, of
adopting SOP 98-1, which will be effective for Consilium in fiscal 2000.
 
     In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities." The Statement
establishes accounting and reporting standards requiring that every derivative
instrument (including certain derivative instruments embedded in other
contracts) be recorded in the balance sheet as either an asset or liability
measured at its fair value. SFAS No. 133 is effective for fiscal years beginning
after June 15, 1999. Management believes the adoption of SFAS No. 133 will have
no effect on Consilium's financial statements.

           COMPARISON OF RIGHTS OF HOLDERS OF APPLIED MATERIALS, INC.
               COMMON STOCK AND HOLDERS OF CONSILIUM COMMON STOCK
 
     Upon consummation of the merger, the holders of Consilium common stock will
become holders of Applied Materials common stock. There are certain material
differences between the rights and privileges of the holders of Consilium common
stock and the holders of Applied Materials common stock.
 
PERCENTAGE OF VOTING STOCK; INFLUENCE OVER AFFAIRS
 
     Upon completion of the merger, the percentage ownership of Applied
Materials by each former Consilium stockholder will be substantially less than
such stockholder's current percentage ownership of Consilium. Accordingly,
former Consilium stockholders will have a significantly smaller voting influence
over the affairs of Applied Materials than they currently enjoy over the affairs
of Consilium.
 
POWER TO CALL SPECIAL STOCKHOLDERS' MEETINGS
 
     According to the Bylaws, as amended, of Consilium, a special meeting of the
Consilium stockholders may be called only by the President or the Board of
Directors of Consilium. The Amended and Restated Bylaws of Applied Materials
also provide that special meetings of the Applied stockholders may be called by
the Chairman of the Board, the President or the Applied Materials Board of
Directors, but further provide that such meetings shall be called by the
Chairman of the Board, the President or the Applied Materials Board of Directors
if so requested in writing by the Applied Materials stockholders holding of
record at least 50% of the outstanding shares of stock entitled to vote at such
a meeting.
 
RIGHTS PLAN
 
     On June 14, 1989, the Applied Materials Board of Directors declared a
dividend of one common stock purchase right (a "Right") for each outstanding
share of Applied Materials common stock to the holders of record on June 26,
1989, and authorized and directed the issuance of one Right with respect to each
share of Applied Materials common stock that becomes outstanding prior to the
occurrence of certain "triggering events" pursuant to the Rights Agreement dated
June 14, 1989 between Applied Materials and Bank of America, N.T. & S.A. By its
terms, the Rights Agreement will expire on June 13, 1999. Each share of Applied
Materials common stock issued in exchange for Consilium common stock includes
one Right. Consilium does not have such a rights agreement.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Consilium, Inc.:
 
     We have audited the accompanying consolidated balance sheets of Consilium,
Inc. (a Delaware Corporation) and subsidiaries as of October 31, 1997 and 1996,
and the related consolidated statements of operations, stockholders' equity and
cash flows for the years then ended. These financial statements are the
responsibility of Consilium's management. Our responsibility is to express an
opinion on these financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Consilium, Inc. and
subsidiaries as of October 31, 1997 and 1996, and the results of their
operations and their cash flows for the years then ended in conformity with
generally accepted accounting principles.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
Board of Directors and Stockholders
Consilium, Inc. and Subsidiaries
 
     We have audited the consolidated statements of operations, stockholders'
equity and cash flows of Consilium, Inc. and subsidiaries for the year ended
October 31, 1995. These financial statements are the responsibility of
Consilium's management. Our responsibility is to express an opinion on these
financial statements based on our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
     In our opinion, the 1995 consolidated financial statements referred to
above present fairly, in all material respects, the consolidated results of
operations and cash flows of Consilium, Inc. and subsidiaries for the year ended
October 31, 1995, in conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                OCTOBER 31, 1997
 
NOTE 1: NATURE OF OPERATIONS AND ORGANIZATION
 
     Consilium, Inc. was incorporated in October 1978 and designs and licenses
integrated manufacturing execution systems (MES) software for the manufacturing
plant floor. Consilium also provides consulting, implementation and training
services for its software products as well as system integration services for
plant automation. Consilium markets its products worldwide to the semiconductor,
electronics, healthcare products and process industries.
 
NOTE 2: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
PRINCIPLES OF CONSOLIDATION AND BASIS OF PREPARATION
 
     The consolidated financial statements include the accounts of Consilium,
Inc. and its wholly owned subsidiaries after elimination of intercompany
accounts and transactions.
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results may differ from those estimates.
 
FOREIGN CURRENCIES
 
     The functional currency of Consilium's wholly owned German subsidiary is
the local currency. Gains and losses resulting from the translation of the
subsidiary's financial statements are reported as a separate component of
stockholders' equity. The functional currency of Consilium's other wholly owned
foreign subsidiaries is the U.S. dollar. Accordingly, translation gains and
losses, which have not been material, are reflected in the accompanying
statements of operations. Exchange gains and losses arising from transactions
denominated in foreign currencies have not been material to date.
 
CASH AND CASH EQUIVALENTS
 
     Consilium considers all highly liquid investments purchased with an
original maturity of three months or less to be cash equivalents.
 
SHORT-TERM INVESTMENTS
 
     At October 31, 1996, Consilium's investments were classified as
available-for-sale and were recorded at fair market value, which approximated
amortized cost and, as such, gross unrealized holding gains and losses were not
material. The fair value of the investments was determined based on quoted
market prices at the reporting dates for those instruments. Realized gains and
losses have not been material to date. The carrying value of Consilium's
available-for-sale investments by major security type consisted of the following
as of October 31, 1996 (in thousands):

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
                                OCTOBER 31, 1997
 
     Approximately $4,500,000 of the total investments in debt securities as of
October 31, 1996 are included in cash and cash equivalents. The remaining
balance is classified as short-term investments. Consilium did not have any
investments in debt and equity securities as of October 31, 1997.
 
DEPRECIATION AND AMORTIZATION
 
     Property and equipment are stated at cost and depreciated on a
straight-line basis over their estimated useful lives of three to five years.
Leasehold improvements are amortized over their estimated useful lives of five
years or the remaining term of the related lease, if shorter.
 
GOODWILL
 
     Goodwill arising from Consilium's acquisitions (see Note 3) is amortized on
a straight-line basis over four to five years. Accumulated amortization was
$496,000 and $65,000 at October 31, 1997 and 1996, respectively.
 
SOFTWARE DEVELOPMENT COSTS
 
     Consilium capitalizes eligible computer software development costs upon
establishment of technological feasibility. The establishment of technological
feasibility and the ongoing assessment of the recoverability of these costs
requires considerable judgment by management with respect to certain external
factors including, but not limited to, anticipated future gross product
revenues, estimated economic life and changes in software and hardware
technology. Amortization of capitalized software development costs begins when
the products are available for general release to customers and is generally
computed on license revenues recognized during the year in relation to total
anticipated license revenues; however, the annual amortization expense, at a
minimum, will not be less than 20% of the capitalized costs.
 
REVENUE RECOGNITION AND DEFERRED REVENUE
 
     Product revenues consist principally of revenues earned under software
license agreements and are generally recognized when the software has been
shipped, Consilium has a right to invoice the customer, collection of the
receivable is probable and there are no significant obligations remaining. If
significant post-delivery obligations exist, the product revenue is deferred
until no significant obligations remain. With respect to sales made through
foreign distributors, revenue is recognized either upon verification of receipt
of a firm purchase order between the distributor and the end user or upon
installation of the software at the end user's facility.
 
     Service revenue primarily consists of software maintenance revenue and
revenue earned for software installation, systems integration and customer
training. Software maintenance revenue consists of fees for providing
unspecified upgrades, user documentation and technical support for software
products. Maintenance revenue is recognized ratably over the term of the
maintenance period. All other service revenue is either recognized as the
services are performed or on the percentage-of-completion method of accounting,
depending upon the nature of the project. If a transaction includes both license
and service elements, license revenue is recognized upon shipment of the
software, provided services do not include significant customization or
modification of the base product and payment terms for the license fee are not
subject to acceptance criteria for the service element, as well as having met
all other product revenue recognition criteria. If these criteria are not met,
the license and service fees are both recognized on the percentage-of-completion
method of accounting.
 
     Deferred revenue consists primarily of the unrecognized portion of revenue
under maintenance and support contracts and systems integration projects and
advance payment of software development fees and license fees.

                                OCTOBER 31, 1997
 
     Consilium adopted Statement of Position (SOP) 97-2, "Software Revenue
Recognition" in the first quarter of fiscal 1998. The adoption of SOP 97-2 did
not have a significant impact on its financial position or results of
operations.
 
CONCENTRATIONS OF CREDIT RISK
 
     Financial instruments which potentially subject Consilium to concentrations
of credit risk consist principally of cash investments and trade receivables.
Consilium has cash investment policies that limit cash investments to
short-term, low risk investments. With respect to trade receivables, Consilium
generally does not require collateral as the majority of Consilium's customers
are large, well established companies in the semiconductor, electronics and
healthcare products and process industries. Consilium establishes an allowance
for doubtful accounts based upon factors surrounding the credit risk of specific
customers, historical trends and other information.
 
STOCK-BASED COMPENSATION
 
     Effective November 1, 1996, Consilium adopted the disclosure provisions of
Statement of Financial Accounting Standards (SFAS) No. 123, "Accounting for
Stock-Based Compensation." In accordance with the provisions of SFAS No. 123,
Consilium applies Accounting Principles Board (APB) Opinion No. 25, "Accounting
for Stock Issued to Employees," and related interpretations in accounting for
its stock option and employee stock purchase plans.
 
COMPUTATION OF NET INCOME (LOSS) PER COMMON SHARE
 
     Effective November 1, 1997, the Company adopted SFAS No. 128, "Earnings Per
Share." All prior-period earnings per share data presented was restated to
conform with SFAS No. 128. SFAS No. 128 requires companies to compute net income
(loss) per share under two different methods, basic and diluted, and to disclose
the methodology used for the calculation.
 
     Basic net income (loss) and diluted net income per common share was
computed by dividing net income (loss) after deduction of preferred stock
dividends by the weighted average number of shares of common stock outstanding
during the period. Diluted net income per share was computed by dividing net
income by the weighted average shares of common stock outstanding and potential
common shares during the period. Potential common shares included in the
dilutive calculation consist of dilutive shares issuable upon the exercise of
outstanding common stock options, warrants and convertible preferred stock.
Potentially dilutive securities of 40,409, 2,126,672, 1,733,070 and 2,257,462
were not included in the computation of diluted earnings per common share
because to do so would have been antidilutive for the years ended October 31,
1996 and 1997 and the nine months ended July 31, 1997 and 1998, respectively.
 
RECLASSIFICATIONS
 
     Certain reclassifications were made to prior year amounts to conform to the
1997 presentation. These reclassifications did not change the previously
reported net income (loss), total assets or total cash flows of Consilium for
prior years.
 
RECENT ACCOUNTING PRONOUNCEMENTS
 
     In February 1997, the FASB issued SFAS No. 129, "Disclosure of information
about Capital Structure," which requires companies to disclose certain
information about their capital structure. SFAS No. 129 will become effective in
the first quarter of Consilium's fiscal year ending October 31, 1998 and its
adoption is not expected to have a material effect on the financial statements
of Consilium.

                                OCTOBER 31, 1997
 
     In 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive Income,"
which establishes standards for reporting and display of comprehensive income
and its components in a full set of general purpose financial statements. SFAS
No. 130 will become effective for Consilium's fiscal year ending October 31,
1999. Consilium anticipates additional disclosure requirements on comprehensive
income upon adoption of SFAS No. 130.
 
     In June 1997, the FASB issued SFAS No. 131, "Disclosures About Segments of
an Enterprise and Related Information," which establishes standards for
disclosure of segment information. SFAS No. 131 will become effective for
Consilium's fiscal year ending October 31, 1999. Consilium anticipates
additional disclosure requirements on segment information upon adoption of SFAS
No. 131.
 
INTERIM FINANCIAL DATA
 
     The interim financial statements as of July 31, 1998 and for the nine
months ended July 31, 1997 and 1998 have been prepared on the same basis as the
year-end financial statements and, in the opinion of management, include all
adjustments (consisting of normal recurring adjustments) necessary to present
fairly the financial information set forth therein, in accordance with generally
accepted accounting principles. Consilium's interim results are subject to
fluctuation. As a result, Consilium believes the results of operations for the
interim period are not necessarily indicative of the results to be expected for
any future period.
 
NOTE 3: ACQUISITIONS
 
     On August 1, 1997, Consilium acquired certain assets of Fast Associates
Pte. Ltd. (FAST), a Singapore corporation specializing in semiconductor factory
automation. Consilium purchased two existing semiconductor factory automation
contracts, certain tangible and intangible assets and assumed certain
liabilities of FAST. The purchase price consisted of an initial 120,000 shares
of Common Stock valued at $476,000 and an additional guaranteed amount of
$1,500,000 to be paid in five equal quarterly installments of $300,000 each.
Such guaranteed amounts may be payable in cash or settled by issuing shares of
Common Stock with a fair market value equal to the quarterly installment amount,
at the option of Consilium. As of October 31, 1997, the first installment of
$300,000 was settled by issuing 75,586 shares of Common Stock. The four
remaining payments will be paid at intervals of ninety days, beginning November
1, 1997. As of October 31, 1997, Consilium has recorded in Accrued Liabilities a
liability of $1,200,000 for the remaining four installments related to this
acquisition. The acquisition was accounted for as a purchase and, accordingly,
the results of FAST from the date of acquisition forward have been recorded in
Consilium's consolidated financial statements. The excess of the purchase price
over the estimated fair value of the net assets acquired of $1,821,000 has been
recorded as goodwill and will be amortized on a straight-line basis over four
years.
 
     In addition, Consilium may be obligated to pay future contingent
performance-based consideration equal to specified percentages of systems
integration and related services net operating margin, and net product license
and maintenance revenue related to FAST recognized by Consilium in certain
countries in Asia for a period of three years ending on August 1, 2000, as
follows: 45% of systems integration/services net operating margin, 10% of
product license net revenue, and 2.5% of product maintenance net revenue. Such
payments may also be made in cash or Common Stock, at the option of Consilium,
and will be accounted for as compensation and expensed in the periods such
amounts are earned.
 
     The following unaudited pro forma information shows the results of
operations for the fiscal years ended October 31, 1997 and 1996 as if the FAST
acquisition had occurred at the beginning of each period presented. The results
are not necessarily indicative of what would have occurred had the acquisition
actually been made at the beginning of the period or of future operations of the
combined companies. The pro forma results for fiscal 1996 combine Consilium's
results for the year ended October 31, 1996 with the results of FAST for the
year ended December 31, 1996. The pro forma results for fiscal 1997 combine
Consilium's results for the year ended October 31, 1997 with the results of FAST
for the period from January 1, 1997 through the date of

     In July 1996, Consilium acquired the Taiwan operations of Systematic
Designs International, Inc. (SDI), a privately-held Washington corporation
specializing in the development of factory automation products and systems
integration services for the semiconductor industry. Consilium purchased two
existing semiconductor plant automation contracts and certain tangible and
intangible assets and assumed certain liabilities of SDI. The total purchase
price of the acquisition was $1,305,000 paid in cash. Under the terms of the
original acquisition agreement, Consilium was required to make additional
performance-based payments, in cash or cash and stock, over a two-year period
ending on July 8, 1998. To the extent such performance-based payments were made,
such amounts were recorded as an adjustment of the purchase price, which
increased goodwill. As of October 31, 1997 and 1996, performance-based payments
of approximately $462,000 and $105,000 had been earned. Subsequent to October
31, 1997, Consilium renegotiated the major terms of the agreement with SDI,
subject to the execution of definitive agreements, such that no additional
performance-based payment would be paid. The acquisition was accounted for as a
purchase and, accordingly, the results of the Taiwan operations of SDI since the
date of acquisition have been recorded in Consilium's consolidated financial
statements. The excess of the purchase price over the estimated fair value of
the net assets acquired ($1,767,000 at October 31, 1997) has been recorded as
goodwill and is being amortized on a straight-line bases over five years.
Comparative pro forma information has not been presented because the Taiwan
operations of SDI are not material to Consilium's consolidated financial
statements.

NOTE 5: LINE OF CREDIT/NOTE PAYABLE
 
     In April 1997, Consilium entered into a revolving line of credit agreement
(the "Line of Credit Agreement") under which it can borrow up to $5,000,000,
based on eligible accounts receivable. The revolving line of credit is secured
by substantially all of Consilium's assets, bears interest at the bank's prime
rate per annum (8.5% at October 31, 1997) and expires on March 15, 1998. At
October 31, 1997, $3,051,000 was outstanding under the revolving line of credit
and $1,949,000 was available for future borrowings subject to compliance with
financial covenants and borrowing base limitations. The Line of Credit Agreement
requires Consilium to maintain certain financial covenants. Consilium was in
default under its credit facility at October 31, 1997 as a result of failing to
meet financial covenants relating to minimum tangible net worth, maximum total
liabilities to tangible net worth and amount of the loss for the fiscal year.
Consilium has not yet obtained a waiver of the default from its lender.
Consilium is currently negotiating with its lender regarding a new credit
facility to replace the existing facility. Although Consilium believes that it
will obtain a waiver and negotiate a new credit facility, there can be no
assurance that Consilium will be able to obtain either the waiver or a credit
facility on terms acceptable to Consilium. Additionally, while Consilium is
currently negotiating with the bank an extension to the expiration date of the
Line of Credit Agreement, there can be no assurance that Consilium will be
successful in negotiating such an extension. In connection with this line of
credit, Consilium granted the bank a warrant to purchase 70,000 shares of the
Common Stock at an exercise price of $3.98 per share. The warrant agreement with
Imperial includes antidilution provisions. However, in no event shall the number
of shares issued under this warrant exceed 100,000, nor shall the exercise price
be less than $3.00 per share. Such warrants are fully exercisable and expire in
April 2002. The bank has certain registration rights with respect to the
underlying Common Stock.
 
     In April 1996, Consilium signed a $2.0 million promissory note, payable to
a bank in equal monthly installments of approximately $41,667 plus interest.
This note was secured by certain assets of Consilium. All amounts due under the
promissory note were repaid in April 1997 when Consilium obtained the above
mentioned Line of Credit.

     Consilium leases its headquarters, research and development facility, sales
offices and certain equipment under noncancelable operating leases. The major
facility leases expire at various dates from 1997 through 2009.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
                                OCTOBER 31, 1997
 
NOTE 7: PREFERRED STOCK:
 
     In August 1997, Consilium sold 3,000 shares of Series A Preferred Stock to
three private institutional investors at a price of $1,000 per share. Proceeds
from the sales were approximately $ 2,799,000, net of cash offering costs of
approximately $201,000. Additionally, in connection with the preferred stock
issuance, Consilium granted the placement agents warrants to purchase 150,000
shares of common stock at a price of $6.33 per share. Such warrants are
immediately exercisable and expire in 2002.
 
     The rights, preferences and privileges of the Series A Preferred
Stockholders are as follows:
 
     Dividends. The holders of Series A Preferred Stock are entitled to
cumulative dividends of $80 per annum per share for the period that such share
of the Series A Preferred Stock is outstanding. Dividends on shares of Series A
Preferred Stock shall be fully cumulative and shall accrue without regard to
whether or not such dividends have been declared and whether or not there are
any funds available for the payment of dividends. If dividends are declared on
the common stock, the holders of Series A Preferred Stock are each entitled to
receive the dividends that they would have received had their preferred stock
been converted into common stock. Dividends on the shares of Series A Preferred
Stock shall be payable in cash, common stock or any combination thereof, as
determined by Consilium. For the year ended October 31, 1997, Consilium accrued
$50,000 of preferred stock dividends.
 
     Liquidation. In the event of any liquidation, dissolution or winding up of
Consilium, the holders of Series A Preferred Stock are entitled to receive
$1,000 per share plus any declared but unpaid dividends, prior and in preference
to any distribution to the holders of common stock.
 
     Consolidation and Merger. If Consilium entered into any consolidation,
merger, combination or other transaction in which the shares of common stock are
exchanged for or changed into other stock or securities, cash and/or other
property, the holders of Series A Preferred Stock are each entitled to acquire
the kind and amount of shares of stock, securities, cash/or other property
receivable upon such consolidation, merger, combination or other transaction as
if their convertible preferred stock had been converted into common stock
immediately prior to such transaction.
 
     Conversion and Registration Rights. Each share of Series A Preferred Stock
is convertible, without the payment of any further consideration, into shares of
common stock of Consilium, as follows:
 
     A. Six months after August 19, 1997 (the "Closing Date"), provided that the
closing bid price of the Common Stock of Consilium as reported on the Nasdaq
National Stock Market ("Nasdaq") on the date of conversion (the "Closing Bid
Price") is $5.00 or greater, each Purchaser may convert each of its Preferred
Shares into a number of shares of Common Stock of Consilium equal to (a) $1,000
divided by (b) the average closing bid price of the Common Stock of Consilium as
reported on Nasdaq for the five consecutive trading days prior to the date of
conversion, discounted by 15%, but in any case no less than $1.95 and no greater
than (i) the difference between the Closing Bid Price and $1.95, plus (ii) the
Closing Bid Price; provided, however, that Consilium shall not be obligated, at
any time prior to nine months after the Closing Date, to convert, in the
aggregate, more than 25% of the total Preferred Shares.
 
     B. Nine months after the Closing Date, provided that the Closing Bid Price
is $5.00 or greater, each Purchaser may convert each of its Preferred Shares
into a number of shares of Common Stock of Consilium equal to (a) $1,000 divided
by (b) the average closing bid price of the Common Stock of Consilium as
reported on Nasdaq for the five consecutive trading days prior to the date of
conversion, discounted by 17%, but in any case no less than $1.95 and no greater
than (i) the difference between the Closing Bid Price and $1.95 plus (ii) the
Closing Bid Price; provided, however, that Consilium shall not be obligated, at
any time prior to one year after the Closing Date, to convert, in the aggregate,
more than 50% of the total Preferred Shares.
 
                                      F-15

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
                                OCTOBER 31, 1997
 
     C. One year after the Closing Date, each Purchaser may convert each of its
Preferred Shares into a number of shares of Common Stock of Consilium equal to
(a) $1,000 divided by (b) the average closing bid price of the Common Stock of
Consilium as reported on Nasdaq for the five consecutive trading days prior to
the date of conversion, discounted by 18%; but in any case no less than $1.95
and no greater than (i) the difference between the Closing Bid Price and $1.95
plus (ii) the Closing Bid Price.
 
     The Preferred Stock cannot be converted for six months following the
Closing Date and will automatically convert, if not earlier converted by the
holders, no later than 24 months following the Closing Date (August 19, 1997).
The holders of Series A Preferred Stock have certain registration rights with
respect to the underlying common stock. In the event the registration statement
to be filed by Consilium is not declared effective by the Commission within one
hundred eighty (180) days from the Closing Date, then Consilium will pay
Purchasers two (2%) percent of the principal amount per month thereafter in
cash, stock, or cash and stock at Consilium's option (the first month shall be
pro rated on a weekly basis) until Consilium procures registration of the
Convertible Preferred Registrable Securities.
 
     The Preferred Stock contains certain conversion discount features as
discussed above. As of October 31, 1997, Consilium has accreted on a ratable
basis $137,000 of the total maximum discount of $658,000 as additional dividends
in the accompanying consolidated financial statements. The remaining discount
will be accrued as additional dividends in fiscal year 1998. The total maximum
discount of 18% assumes the Preferred Stock would not be converted prior to one
year after the Closing.
 
NOTE 8: COMMON STOCK
 
EMPLOYEE STOCK PURCHASE PLAN
 
     Under Consilium's 1989 Employee Stock Purchase Plan (the "Purchase Plan"),
880,000 shares of Common Stock of Consilium have been reserved for issuance.
Under the Purchase Plan, employees may purchase common stock through payroll
deductions at 85% of the lesser of the fair market value on the first or last
day of six-month offering periods. At October 31, 1997, there are no remaining
shares available for purchase under the Purchase Plan.
 
EMPLOYEE STOCK OPTION PLANS
 
     The 1983 and 1993 Employee Stock Option Plans (the "1983 and 1993 Plans")
were terminated in December 1996 and there are no further options available for
issuance under these plans. Both qualified and non-qualified options have been
granted to employees at prices not less than the fair market value at date of
grant under the 1983 and 1993 Plans. All options granted under the 1983 and 1993
Plans are exercisable immediately and generally expire five years from date of
grant. Options generally vest over four years and, if exercised prior to
vesting, are subject to repurchase at the original purchase price. At October
31, 1997, a total of 280,112 options were vested under the 1983 and 1993 Plans.
 
     In December 1996, Consilium adopted the 1996 Stock Option Plan (the "1996
Plan"). Consilium has authorized 390,000 shares of common stock for issuance
under the 1996 Plan. In addition, all authorized, but unissued, canceled or
reacquired shares under the 1983 and 1993 Plans will be available for issuance
under the 1996 Plan. Under the terms of the 1996 Plan, Consilium may grant stock
incentive stock options or non-statutory stock options to employees, officers,
directors and consultants at prices not less than fair market value at date of
grant. Options granted under the 1996 Plan generally become exercisable at a
rate of one-fourth of the shares subject to the option at the end of the first
year and 1/48 of the shares subject to the option at the end of each calendar
month thereafter. The maximum term of a stock option under the 1996 Plan is ten
years, but if the optionee at the time of grant has voting power over more than
10% of Consilium's outstanding capital stock, the maximum term is five years. As
of October 31, 1997, a total of 156,895 options were vested under the 1996 Plan.

                                OCTOBER 31, 1997
 
     In March 1997, upon approval by Consilium's Board of Directors, Consilium
repriced 873,642 options originally issued at prices ranging from $6.00 to
$12.141. The options were repriced at the then current market value of the
Common Stock of $3.75.

     In addition, Consilium has a separate nonqualified stock option agreement
with an employee for 103,000 shares at exercise prices ranging from $2.625 to
$6.50 per share. As of October 31, 1997, a total of 17,875 shares were vested
under the terms of the option agreement.
 
OUTSIDE DIRECTOR STOCK OPTION PLAN
 
     In 1990, Consilium adopted a stock option plan under which options for a
total of up to 100,000 shares of Common Stock may be granted to non-executive
directors of Consilium (the "Outside Director Plan"). The Outside Director Plan
provides for the granting of nonqualified stock options at the average of the
high and low prices on the date of grant. Options expire 10 years after the date
of grant. At October 31, 1997, a total of 92,500 options had been granted at
exercise prices ranging between $4.00 and $11.75 per share, of which none were
exercised. In addition, Consilium has separate option agreements with
non-executive directors which totaled 7,500 shares at an exercise price of $6.25
per share. As of October 31, 1997, a total of 43,750 shares were vested under
the terms of these option agreements.
 
STOCK-BASED COMPENSATION PLANS
 
     Consilium applies APB Opinion No. 25 "Accounting for Stock Issued to
Employees" and related interpretations in accounting for the Purchase Plan, the
1983 and 1993 Plans, the 1996 Plan and the Outside Director Plan (the "Plans")
described above. Accordingly, no compensation cost has been recognized for the
Plans. If compensation cost for the Plans had been determined consistent with

     The fair value of each option grant was estimated on the date of grant
using the Black-Scholes option pricing model with the following weighted average
assumptions for fiscal years 1997 and 1996: risk-free interest rates in the
range of 5.52% to 6.49%, expected dividend yields of zero; expected volatility
factor of the market price of the Common Stock of 75.4%; and expected lives of
the option of one year and 0.57 years after vest date, respectively. Because the
method of accounting prescribed by SFAS No. 123 has not been applied to options
granted prior to November 1, 1995, and because the Black-Scholes option
valuation model was developed for traded options and requires the input of
subjective assumptions, the resulting pro forma effect of compensation cost may
not be representative of that to be expected in future years.

WARRANTS
 
     In connection with the Line of Credit Agreement (See Note 5), Consilium
granted the bank a warrant to purchase 70,000 shares of the Common Stock at an
exercise price of $3.98 per share. The warrant agreement with Imperial includes
antidilution provisions. However, in no event shall the number of shares issued
under this warrant exceed 100,000, nor shall the exercise price be less than
$3.00 per share. Such warrant is fully exercisable and expires in April 2002.
The fair value of the warrant was estimated to be approximately $109,000 on the
date of grant using the Black-Scholes option pricing model with the following
assumptions: risk-free interest rate of 6.5%; expected dividends yields of zero;
expected volatility factor of the market price of the Common Stock of 75%; and
expected life of the warrant of 2 years.
 
     Consilium is amortizing the fair value of the warrants of $109,000 over the
term of the Line of Credit of one year as additional interest expense. For the
fiscal year ended October 31, 1997, $65,000 had been amortized and is reflected
in interest expense in the accompanying statement of operations.
 
     In connection with the issuance of Series A Convertible Preferred Stock
(See Note 7), Consilium granted the placement agents warrants to purchase an
aggregate of 150,000 shares of the Common Stock at an

exercise price of $6.33. The warrants are fully exercisable and expire in August
2002. The fair value of the warrants was estimated to be approximately $282,000
on the date of grant using the Black-Scholes option pricing model with the
following assumptions: risk-free interest rate of 6.5%; expected dividends
yields of zero; expected volatility factor of the market price of the Common
Stock of 75%; and expected life of the warrants of 2 years.
 
     The fair value of the warrants issued to the placement agents is being
accreted as additional Preferred Stock dividends over the period beginning with
the issuance of the warrants to the earliest date of conversion of the Preferred
Stock. As of October 31, 1997, Consilium had accreted $118,000 of the total fair
value of the warrants of $282,000 as additional dividends in the accompanying
consolidated financial statements. The remaining discount will be accreted as
additional dividends in the first two quarters of fiscal year 1998.

     Consilium has recorded a valuation allowance against its net deferred tax
assets due to the uncertainty surrounding the realization of such assets.
Management evaluates on a quarterly basis the recoverability of the deferred tax
assets and the level of the valuation allowance. The valuation allowance will be
reduced at such time that it is determined that it is more likely than not that
the deferred tax assets are realizable.
 
     At October 31, 1997, Consilium has federal net operating loss carryforwards
of approximately $23,523,000 and state net operating loss carryforwards of
approximately $7,786,000. In addition, Consilium has approximately $3,469,000
and $1,120,000 in general business credit carryforwards for federal tax and
state tax reporting purposes, respectively, as well as approximately $2,682,000
of foreign tax credits. These carryforwards and credits expire between 1998 and
2012 for both federal and state purposes, if not used before such time to offset
future taxable income or taxes payable.

NOTE 11: SUBSEQUENT EVENTS (UNAUDITED)
 
SALE OF HEALTHCARE PRODUCTS AND PROCESS INDUSTRIES GROUP
 
     In February 1998, Consilium sold certain assets of its Healthcare Products
and Process Industries Group that focused on the FlowStream product line (the
"Healthcare Group"), pursuant to an Asset Purchase Agreement dated February 19,
1998 (the "Asset Purchase Agreement") by and among Base Ten FlowStream, Inc.
(the "Buyer"), Base Ten Systems, Inc. (the "Parent" and together with the Buyer,
"Base Ten") and Consilium, for consideration consisting of $1,500,000 in cash,
20% of all annual revenues in excess of $3,200,000 recognized by Base Ten from
the licensing of the FlowStream product line during the 1998 and 1999 calendar
years, and assumption by Base Ten of substantially all of the Healthcare Group's
liabilities on a going-forward basis, with some specific obligations being
retained by Consilium. Pursuant to the Asset Purchase Agreement, Base Ten
assumed certain liabilities as of the acquisition date, purchased fixed assets
with a net book value of approximately $500,000 and assumed Consilium's rights
under certain contracts with customers and other third parties relating to the
FlowStream product line, except certain patents used within Consilium by both
the Healthcare Group and the Semiconductor and Electronics Business Group. With
regards to these patents, Consilium granted to Base Ten a worldwide
royalty-free, non-transferable (except with substantially all of the assets of
the FlowStream Business) license, for the lives of the patents, without the
right to sublicense, to the exclusive use of such patents for developing,
producing, manufacturing and selling manufacturing execution systems limited to
the field of healthcare products (pharmaceutical, medical device and
biotechnology) and chemical industries. In addition, Consilium agreed not to
compete in the business of developing, producing, manufacturing and selling
manufacturing execution systems under the trademark of "FlowStream" for
healthcare products and chemical industries for three years. Also pursuant to
the Asset Purchase Agreement, Consilium agreed to indemnify Base Ten for up to
$1,500,000 for certain representations and warranties relating to intellectual
property and up to an unlimited amount for certain post-closing covenants, any
excluded obligations (as defined in the Asset Purchase Agreement) and any tax
losses (as defined in the Asset Purchase Agreement).
 
NEW LINE OF CREDIT AND TERM LOAN
 
     On July 24, 1998, Consilium entered into a new banking arrangement. Under
the new facility, Consilium can borrow up to $6,500,000, including a $2,750,000
three year term loan (the "Term Loan Agreement"), and an additional line of
credit (the "Revolving Facility Agreement") of up to $3,750,000 based on
eligible accounts receivable. The term loan agreement is secured by
substantially all of Consilium's assets, bears interest at 1.0% above the prime
rate per annum (9.5% at July 31, 1998) and expires on July 24, 2001. The

revolving facility agreement is secured by substantially all of Consilium's
assets, bears interest at 0.5% above the prime rate per annum (9.0% at July 31,
1998) and expires on July 24, 1999. At July 31, 1998, $2,750,000 was outstanding
under the Term Loan Agreement and no borrowings were outstanding under the
Revolving Facility Agreement. The Term Loan and Revolving Facility Agreements
require Consilium to maintain certain financial covenants. Consilium is in
compliance with all financial covenants.
 
PREFERRED STOCK CONVERSION
 
     In October 1998, pursuant to the terms of the Preferred Stock Agreement,
the holders of Series A Preferred Stock converted all shares outstanding into
1,538,457 shares of Common Stock based on a conversion price per share of $1.95.
 
PROPOSED MERGER WITH APPLIED MATERIALS
 
     On October 12, 1998, Consilium entered into a definitive merger agreement
with Applied Materials, Inc. Under the terms of the agreement, upon closing of
the merger, each holder of Consilium Common Stock will receive between 0.182 and
0.165 of a share of Applied Materials Common Stock in exchange for one share of

                AGREEMENT AND PLAN OF MERGER AND REORGANIZATION
 
     THIS AGREEMENT AND PLAN OF MERGER AND REORGANIZATION ("Agreement") is made
and entered into as of October 12, 1998, by and among: APPLIED MATERIALS, INC.,
a Delaware corporation ("Parent"); PENNSYLVANIA ACQUISITION SUB, INC., a
Delaware corporation and a wholly owned subsidiary of Parent ("Merger Sub"); and
CONSILIUM, INC., a Delaware 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 Delaware General
Corporation Law (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, certain stockholders of the Company are entering into Voting
Agreements pursuant to which they are agreeing to vote in favor of the adoption
and approval of this Agreement and the approval of the Merger.
 
                                   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 the Delaware General
Corporation Law (the "DGCL").
 
     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, located at 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 second business day after the
satisfaction or waiver of the conditions set forth in Sections 6 and 7.
Contemporaneously with or as promptly as practicable after the Closing, the
parties hereto shall cause a properly executed certificate of merger conforming
to the requirements of the DGCL (the "Certificate of Merger") to be filed with
the Secretary of State of the State of Delaware. The Merger shall take effect at
the time the Certificate of Merger is filed with the Secretary of State of the
State of Delaware or at such later time as may be specified in the Certificate
of Merger (the "Effective Time").
 
     1.4  Certificate of Incorporation and Bylaws; Directors and
Officers. Unless otherwise determined by Parent prior to the Effective Time:
 
          (a) the Certificate of Incorporation of the Surviving Corporation
     shall be amended and restated as of 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
 
                                        1
<PAGE>   126
 
          (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) Subject to Sections 1.5(b), 1.5(c) and 1.5(e), 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 or Company Preferred Stock then
     held by the Company or any Subsidiary of the Company (or held in the
     Company's treasury) shall be canceled and retired and shall cease to exist
     at the Effective Time, and no consideration shall be delivered in exchange
     therefor;
 
          (ii) any shares of Company Common Stock or Company Preferred Stock
     then held by Parent, Merger Sub or any other Subsidiary of Parent shall be
     canceled and retired and shall cease to exist at the Effective Time, and no
     consideration shall be delivered in exchange therefor;
 
          (iii) each share of the common stock, $0.001 par value per share, of
     Merger Sub then outstanding shall be converted into one share of common
     stock of the Surviving Corporation; and
 
          (iv) except as provided in clauses "(i)" and "(ii)" of this sentence,
     each share of Company Common Stock then outstanding shall be converted into
     the right to receive that fraction of a share of Parent Common Stock equal
     to the "Exchange Ratio." The Exchange Ratio shall be equal to a fraction
     (rounded to the nearest third decimal point), (A) the numerator of which
     shall be equal to $5.50, and (B) the denominator of which shall be equal to
     the Parent Average Stock Price; provided, however, that if the Parent
     Average Stock Price is equal to or less than $30.25, then the Exchange
     Ratio shall be 0.182, and if the Parent Average Stock Price is equal to or
     greater than $33.43, then the Exchange Ratio shall be 0.165.
 
     (b) Notwithstanding anything to the contrary contained in this Agreement,
if the "Fully-Diluted Number of Shares" (as defined below) exceeds the "Maximum
Number of Shares" (as defined below), then the Exchange Ratio shall be equal to
the product of: (1) the number that would have constituted the Exchange Ratio if
the Exchange Ratio were calculated in accordance with Section 1.5(a)(iv);
multiplied by (2) a fraction, the numerator of which shall be the Maximum Number
of Shares, and the denominator of which shall be the Fully Diluted Number of
Shares. For purposes of this Section 1.5(b):
 
          (i) the "Fully-Diluted Number of Shares" shall be equal to the sum of:
 
             (A) the number of shares of Company Common Stock outstanding
        immediately prior to the Effective Time (assuming that shares of Company
        Common Stock had been issued pursuant to the ESPP in the manner
        described in Section 5.4(d));
 
             (B) the number of shares of Company Common Stock issuable upon the
        conversion of any shares of Company Preferred Stock outstanding
        immediately prior to the Effective Time;
 
             (C) the number of shares of Company Common Stock issuable upon the
        exercise of any Company Options outstanding immediately prior to the
        Effective Time (whether or not such Company Options are then
        exercisable); and
 
             (D) the number of shares of Company Common Stock issuable upon the
        exercise of any Company Warrants outstanding immediately prior to the
        Effective Time (whether or not such Company Warrants are then
        exercisable); and
 
          (ii) the "Maximum Number of Shares" shall be equal to 12,798,447.
 
     (c) 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,
consolidation of shares,
 
                                        2
<PAGE>   127
 
reclassification, recapitalization or other similar transaction, then the
Exchange Ratio shall be appropriately adjusted.
 
     (d) If any shares of Company Common Stock or Company Preferred 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 or
Company Preferred 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 Surviving Corporation 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.
 
     (e) 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, Company Preferred
Stock or Company Warrants 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 Section 1.6) or warrants, as the case may be, be paid in cash the
dollar amount (rounded to the nearest whole cent), without interest, determined
by multiplying such fraction by the Parent Average Stock Price.
 
     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) Harris Trust and Savings Bank or such other reputable bank or trust
company selected by Parent prior to the Closing Date shall act as exchange agent
in the Merger (the "Exchange Agent"). As soon as practicable 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(e). 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 and the Company 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
                                        3
<PAGE>   128
 
lieu of any fractional share of Parent Common Stock), and (2) the Company Stock
Certificate so surrendered shall be canceled. In the event of a transfer of
ownership of Company Common Stock which is not registered in the transfer
records of the Company, a certificate representing the proper number of shares
of Parent Common Stock may be issued to a transferee if the Company Stock
Certificate is presented to the Exchange Agent, accompanied by all documents
required to evidence and effect such transfer and by evidence that any
applicable stock transfer taxes have been paid. 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 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) 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 which such holder has the right to receive upon
surrender thereof 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).
 
     (d) Any portion of the Exchange Fund that remains undistributed to holders
of Company Stock Certificates as of the date 360 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.
 
     (e) 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.
 
     (f) Neither Parent nor the Surviving Corporation shall be liable to any
holder or former holder of Company Common Stock or Company Preferred 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  Preferred Stock.
 
     (a) Subject to Section 4.2(b)(xiv), the Company shall use all reasonable
efforts to:
 
          (i) cause each holder of Company Preferred Stock who has not converted
     all of such holder's Company Preferred Stock into Company Common Stock
     prior to the Effective Time to enter into an agreement with Parent pursuant
     to which each share of Company Preferred Stock held by such holder which
     has not been converted into Company Common Stock prior to the Effective
     Time will, at the Effective Time, be exchanged for a number of shares of
     Parent Common Stock equal to the sum of (A) the number of shares of Parent
     Common Stock that a holder of a share of Company Preferred Stock would have
     received if (1) such share of Company Preferred Stock had been converted
     into Company Common Stock immediately prior to the Effective Time, and (2)

                                        4
<PAGE>   129
 
     plus (B) the number of shares of Parent Common Stock as is equal to the
     quotient of (1) the sum of (x) all dividends accrued as of the Effective
     Time with respect to such share of Company Preferred Stock and (y) the
     present value of all dividends that would accrue with respect to such share
     of Company Preferred Stock if such share were to be held from the Effective
     Time until August 19, 1999 and such dividends were to be calculated in
     accordance with the Company's Certificate of Incorporation and Certificate
     of Designation of Series A Convertible Preferred Stock (it being understood
     that a discount factor of 7% shall be used in calculating such present
     value), divided by (2) the Parent Average Stock Price;
 
          (ii) cause each holder of Company Preferred Stock who has converted
     Company Preferred Stock into Company Common Stock prior to the Effective
     Time to confirm in a writing delivered to Parent and the Company prior to
     the Effective Time (which writing shall be in a form reasonably
     satisfactory to Parent) that such holder received (upon the conversion of
     such Company Preferred Stock into Company Common Stock) the number of
     shares of Company Common Stock which such holder was entitled to receive
     pursuant to the Company's Certificate of Incorporation, Certificate of
     Designation of Series A Convertible Preferred Stock and otherwise; and
 
          (iii) cause each holder of Company Preferred Stock who, prior to the
     Effective Time, has not converted all of such holder's shares of Company
     Preferred Stock into Company Common Stock or entered into an agreement of
     the type referred to in Section 1.8(a)(i), to enter into an agreement with
     Parent and the Company (in a form reasonably satisfactory to Parent) which
     specifies the number of shares of Parent Common Stock into which such
     Company Preferred Stock will be convertible after the Effective Time.
 
     (b) Persons who hold any shares of Company Preferred Stock that are not
converted into Company Common Stock prior to the Effective Time or exchanged for
Parent Common Stock pursuant to the exchange offer referred to in Section
1.8(a)(i) shall, in accordance with the Company's Certificate of Incorporation
and Certificate of Designation of Series A Convertible Preferred Stock, continue
to hold such shares of Company Preferred Stock after the Effective Time in
accordance with their terms (it being understood that, in accordance with the
Company's Certificate of Incorporation and Certificate of Designation of Series
A Convertible Preferred Stock, after the Effective Time, each such share of
Company Preferred Stock will be convertible into the number of shares of Parent
Common Stock that would have been issued in respect thereof if (i) such share of
Company Preferred Stock had been converted into Company Common Stock immediately
prior to the Effective Time, and (ii) such Company Common Stock had been
converted into the right to receive Parent Common Stock in accordance with
Section 1.5(a)(iv)).
 
     1.9  Warrants.
 
     (a) Neither Parent nor any other Person shall assume those certain warrants
to purchase shares of Company Common Stock issued to Imperial Bancorp pursuant
to that certain Warrant To Purchase Stock dated April 1, 1997 (the "Imperial
Bancorp Warrant"); therefore, in accordance with the terms of the Imperial
Bancorp Warrant, any portion of such warrants that has not been exercised as of
the Effective Time shall be deemed to have been automatically converted pursuant
to Section 1.2 of the Imperial Bancorp Warrant into shares of Company Common
Stock.
 
     (b) At the Effective Time, all rights with respect to Common Stock under
each Placement Agent Warrant then outstanding shall be converted into and become
rights with respect to Parent Common Stock, and Parent shall assume each such
Placement Agent Warrant in accordance with the terms (as in effect as of the
date of this Agreement) of the warrant agreement by which it is evidenced. From
and after the Effective Time, (i) each Placement Agent 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 Placement Agent Warrant shall
be equal to the number of shares of Company Common Stock subject to such
Placement Agent Warrant immediately prior to the Effective Time multiplied by
the Exchange Ratio, rounding down to the nearest whole share (with the cash
value of any fraction of a share of Parent Common Stock, less the exercise price
applicable to such fraction of a share, being payable for the portion of such
assumed Placement Agent Warrant relating to any such fraction of a share of
Parent Common Stock), (iii) the per share exercise price
                                        5
<PAGE>   130
 
under each such Placement Agent Warrant shall be adjusted by dividing the per
share exercise price under such Placement Agent Warrant by the Exchange Ratio
and rounding up to the nearest cent and (iv) any restriction on the exercise of
any such Placement Agent Warrant shall continue in full force and effect and the
term, exercisability, vesting schedule and other provisions of such Placement
Agent Warrant shall otherwise remain unchanged; provided, however, that each
Placement Agent Warrant assumed by Parent in accordance with this Section 1.9(b)
shall, in accordance with its terms, be subject to further adjustment as
appropriate to reflect any stock split, division or subdivision of shares, stock
dividend, reverse stock split, consolidation of shares, reclassification,
recapitalization or other similar transaction subsequent to the Effective Time.
 
     1.10  Appraisal Rights.
 
     (a) Notwithstanding anything to the contrary contained in this Agreement,
Appraisal Shares (as defined in Section 1.10(c)) shall not be converted into or
represent the right to receive Parent Common Stock in accordance with Section
1.5(a) (or cash in lieu of fractional shares in accordance with Section 1.5(e)),
and each holder of Appraisal Shares shall be entitled only to such rights with
respect to such Appraisal Shares as may be granted to such holder in Section 262
of the DGCL. From and after the Effective Time, a holder of Appraisal Shares
shall not have and shall not be entitled to exercise any of the voting rights or
other rights of a stockholder of the Surviving Corporation. If any holder of
Appraisal Shares shall fail to perfect or shall waive, rescind, withdraw or
otherwise lose such holder's right of appraisal under Section 262 of the DGCL,
then (i) any right of such holder to require the Company to purchase the
Appraisal Shares for cash shall be extinguished and (ii) such shares shall
automatically be converted into and shall represent only the right to receive
(upon the surrender of the certificate or certificates representing such shares)
Parent Common Stock in accordance with Section 1.5(a) (and cash in lieu of any
fractional share in accordance with Section 1.5(e)).
 
     (b) The Company (i) shall give Parent prompt written notice of any demand
by any stockholder of the Company for appraisal of such stockholder's shares of
Company Preferred Stock pursuant to the DGCL and of any other notice, demand or
instrument delivered to the Company pursuant to the DGCL, and (ii) shall give
Parent's Representatives the opportunity to participate in all negotiations and
proceedings with respect to any such notice, demand or instrument. The Company
shall not make any payment or settlement offer with respect to any such notice
or demand unless Parent shall have consented in writing to such payment or
settlement offer.
 
     (c) For purposes of this Agreement, "Appraisal Shares" shall refer to any
shares of Company Preferred Stock outstanding immediately prior to the Effective
Time that are held by stockholders who are entitled to demand and who properly
demand appraisal of such shares pursuant to, and who comply with the applicable
provisions of, Section 262 of the DGCL.
 
     1.11  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.
 
     1.12  Accounting Consequences. For financial reporting purposes, the Merger
is intended to be accounted for as a "pooling of interests."
 
     1.13  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.

generally accepted accounting principles, Accounting Principles Board Opinion
No. 16 and all published rules, regulations and policies of the SEC.

     4.3  No Solicitation.
 
     (a) The Company shall not directly or indirectly, and shall not authorize
or permit any of the other Acquired Corporations or any Representative of any of
the Acquired Corporations directly or indirectly to, (i) solicit, initiate,
encourage or induce the making, submission or announcement of any Acquisition
Proposal or take any action that could reasonably be expected to lead to an

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 adoption and approval of this
Agreement by the Required Company Stockholder Vote, the Company shall not be
prohibited by this Section 4.3(a) from furnishing nonpublic information
regarding the Acquired Corporations to, or entering into discussions with, any
Person in response to a Superior Offer that is submitted 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 consultation with its outside legal counsel, that the failure to
take such action would be inconsistent with the fiduciary obligations of such
board of directors to the Company's stockholders under applicable law, (3) prior
to furnishing any such nonpublic information to, or entering into discussions
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 with, such Person, and the Company receives from such
Person an executed confidentiality agreement containing customary limitations on
the use and disclosure of all nonpublic written and oral information furnished
to such Person by or on behalf of the Company, 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 which is
conditioned on completion of due diligence (and regarding which the board of
directors of the Company determines, in good faith, based on the advice of its
financial advisor, that financing is likely to be obtained) shall be deemed to
constitute a "Superior Offer" if such offer otherwise meets the definition of
"Superior Offer" set forth in Exhibit A (other than the financing portion of
such definition). Without limiting the generality of the foregoing, the Company
acknowledges and agrees that any violation of any of the restrictions set forth
in the preceding sentence 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 advise Parent orally and in writing of any
Acquisition Proposal (including the identity of the Person making or submitting
such Acquisition Proposal and the terms thereof) that is made or submitted by
any Person during the Pre-Closing Period. The Company shall keep Parent fully
informed with respect to the status of any such Acquisition Proposal and any
modification or proposed modification thereto.

the SEC the Form S-4 Registration Statement, in which the Prospectus/Proxy

initially be filed with the SEC on a confidential basis as a proxy statement of
Parent under the Securities Act); (ii) until such time as Parent has determined
that it is reasonably likely that the SEC will promptly declare the Form S-4

Proxy Statement/Prospectus 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
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, convene and hold a meeting of the holders
of Company Common Stock to consider, act upon and vote upon the adoption and
approval of this Agreement and the approval of the Merger (the "Company
Stockholders' Meeting"). The Company Stockholders' Meeting will be held as
promptly as practicable and in any event within 45 days after the Form S-4
Registration Statement is declared effective under the Securities Act. The
Company shall ensure that the Company Stockholders' Meeting is called, noticed,
convened, held and conducted, and that all proxies solicited in connection with
the Company Stockholders' Meeting are solicited, in compliance with all
applicable Legal Requirements. The Company's obligation to call, give notice of,
convene and hold the Company Stockholders' Meeting in accordance with this
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, amendment or modification of the
recommendation of the board of directors of the Company with respect to the
Merger.
 
     (b) Subject to Section 5.2(c): (i) the board of directors of the Company
shall unanimously recommend that the Company's stockholders vote in favor of and
adopt and approve this Agreement and approve the Merger at the Company
Stockholders' Meeting; (ii) the Prospectus/Proxy Statement shall include a
statement to the effect that the board of directors of the Company has
unanimously recommended that the Company's stockholders vote in favor of and
adopt and approve this Agreement and approve the Merger at the Company
Stockholders' Meeting; and (iii) neither the board of directors of the Company
nor any committee thereof shall withdraw, amend or modify, or propose or resolve
to withdraw, amend or modify, in a manner adverse to Parent, the unanimous
recommendation of the board of directors of the Company that the Company's
stockholders vote in favor of and adopt and approve this Agreement and approve
the Merger. For purposes of this Agreement, said recommendation of the board of
directors of the Company shall be deemed to have been modified in a manner
adverse to Parent if said recommendation shall no longer be unanimous.
 
     (c) Nothing in Section 5.2(b) shall prevent the board of directors of the
Company from withdrawing, amending or modifying its unanimous recommendation in
favor of the Merger at any time prior to the adoption and approval of this
Agreement by the Required Company Stockholder Vote if (i) a Superior Offer
 
                                       31
<PAGE>   156
 
is made to the Company and is not withdrawn, (ii) neither the Company nor any of
its Representatives shall have violated any of the restrictions set forth in
Section 4.3, (iii) the board of directors of the Company concludes in good
faith, after consultation with its outside counsel, that, in light of such
Superior Offer, it would be inconsistent with the fiduciary obligations of the
board of directors of the Company to the Company's stockholders under applicable
law not to withdraw, amend or modify such recommendation, (iv) the Company
provides Parent with at least 24 hours prior notice of any meeting of the
Company's board of directors at which such board of directors is expected to
consider such Superior Offer, and (v) the Company's board of directors does not
withdraw, amend or modify its unanimous recommendation in favor of the Merger
for at least 48 hours after the Company provides Parent with the name of the
Person making such Superior Offer and a copy of such Superior Offer. Nothing
contained in this Section 5.2 shall limit the Company's obligation to call, give
notice of, convene and hold the Company Stockholders' Meeting (regardless of
whether the unanimous recommendation of the board of directors of the Company
shall have been withdrawn, amended or modified).
 
     5.3  Regulatory Approvals. Each party shall use all reasonable efforts to
file, as promptly 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 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 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 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, 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. 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 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 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.
 
     5.4  Stock Options.
 
     (a) Subject to Section 5.4(b), at the Effective Time, all rights with
respect to Company Common Stock under each Company Option then outstanding shall
be converted into and become rights with respect to Parent Common Stock, and
Parent shall assume each such Company Option 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, the stock option agreement by which it is evidenced and any
applicable Change of Control Agreement. From and after the Effective Time, (i)
each Company Option 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 shall be equal to the number of shares of Company
Common Stock subject to such Company Option 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 shall be
adjusted by dividing the per share exercise price under such Company Option by
the Exchange Ratio and rounding up to the nearest cent and (iv) any restriction
on the exercise of any such Company Option shall continue in full force and
effect and the term, exercisability, vesting schedule and other provisions of
such Company Option shall
 
                                       32
<PAGE>   157
 
otherwise remain unchanged; provided, however, that each Company Option 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, division or subdivision of shares, stock dividend, reverse stock split,
consolidation of shares, reclassification, recapitalization or other similar
transaction subsequent to the Effective Time. Parent shall file with the SEC,
within 7 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). As soon as practicable after the Effective Time (but
in no event later than 30 days thereafter), Parent shall deliver to each holder
of a Company Option an appropriate notice setting forth such holder's rights
with respect to such Company Option and indicating that such Company Option
shall continue in effect on the same terms and conditions as were in effect
immediately prior to the Effective Time (subject to the adjustments required
pursuant to Section 5.4(a)).
 
     (b) Notwithstanding anything to the contrary contained in this Section 5.4,
in lieu of assuming outstanding Company Options in accordance with Section
5.4(a), Parent may, at its election, cause such outstanding Company Options to
be replaced by issuing reasonably equivalent replacement stock options in
substitution therefor ("Replacement Options"). The number of shares of Parent
Common Stock subject to a Replacement Option, as well as the per share exercise
price of such Replacement Option, shall be determined in the manner specified in
Section 5.4(a). If Parent elects to substitute Replacement Options in lieu of
assuming outstanding Company Options, Parent shall take all corporate action
necessary to approve the Replacement Options described in this Section 5.4(b) in
a manner qualifying under Section 424(a) of the Code and shall deliver an
agreement evidencing such Replacement Options to each applicable holder of a
Company Option within 30 days after the Effective Time. Shares of Parent Common
Stock issuable pursuant to the Replacement Options granted pursuant to this
Section 5.4(b) shall be registered on the Form S-8 Registration Statement
referred to in Section 5.4(a).
 
     (c) 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 required pursuant to the ESPP to reflect the
reduced offering period but otherwise treating such offering period as a fully
effective and completed offering period for all purposes of such Plan. Prior to
the Effective Time, the Company shall take all actions that are necessary to
give effect to the transactions contemplated by this Section 5.4(d); provided,
however, that the change in the offering period referred to in this Section
5.4(d) shall be conditioned upon the consummation of the Merger.
 
     5.5  Employee Benefits. Parent agrees that all employees of the Company who
continue employment with Parent after the Effective Time shall be eligible to
participate in Parent's health, vacation and other employee benefit plans, to
the same extent as employees of Parent in similar positions and at similar grade
levels (it being understood that such employees' shall be eligible to begin to
participate (i) in Parent's employee stock purchase plan upon the commencement
of the first new offering period that commences following the Effective Time,
and (ii) in Parent's other employee benefit plans in accordance with the terms
of such plans; provided, however, that in the case of plans for which the
Company maintains a plan offering the same type of benefit, such eligibility
need not be offered by Parent until the corresponding plan of the Company ceases
to be available after the Effective Time). As soon as administratively feasible
following the Effective Time, Parent agrees to take whatever action is necessary
to transition Company employees into Parent's employee benefits plans as
contemplated by the first sentence of this Section 5.5. Further, until such time
that the continuing Company employees are covered under an employee benefit plan
of Parent, they shall continue to be covered under the corresponding Company
Plan that offers the same type of benefit. Parent also agrees to provide each
such continuing employee with full credit for service as an employee of the
Company or any affiliate thereof prior to the Effective Time for the following
purposes only: for purposes of eligibility, vesting and determination of the
level of benefits under any employee benefit plan or arrangement maintained
                                       33
<PAGE>   158
 
by Parent, including Parent's 401(k) plan, and for Parent's vacation program.
Notwithstanding the foregoing, to the extent permitted by law, Parent reserves
the right to enforce, on a nondiscriminatory basis, any otherwise applicable
pre-existing condition limitation under its medical plan with respect to any
Company employee who does not enroll in Parent's medical plan at the time
Parent's medical plan is first made available to such Company employee.
 
     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),
shall survive the Merger and shall be observed by the Surviving Corporation to
the fullest extent available under Delaware law for a period of five years from
the Effective Time.
 
     (b) From the Effective Time until the fifth 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 (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 an annual
premium for the Existing Policy (or for any substitute policies) in excess of
$168,750. In the event any future annual premium for the Existing Policy (or any
substitute policies) exceeds $168,750, 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 $168,750.
 
     (c) If the Surviving Corporation does not have sufficient capital to comply
with its obligations under Section 5.6, Parent shall provide the Surviving
Corporation with such capital.
 
     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 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." The Company agrees to provide to PricewaterhouseCoopers LLP and
Arthur Andersen LLP such letters as shall be reasonably requested by
PricewaterhouseCoopers LLP or Arthur Andersen LLP with respect to the letters
referred to in Sections 2.26, 3.8, 6.6(e) and 6.6(f).
 
     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
effectuate 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 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
                                       34
<PAGE>   159
 
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 Intellectual Property, or to commit to cause any
of the Acquired Corporations to license or otherwise make available to any
Person any technology, software or other Intellectual Property; (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; or (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.
 
     5.9  Disclosure. Parent and the Company shall consult with each other
before issuing any press release or otherwise making any public statement with
respect to the Merger or any of the other transactions contemplated by this
Agreement. Without limiting the generality of the foregoing, the Company shall
not, and shall not permit any of its Subsidiaries or any Representative of any
of the Acquired Corporations to, make any disclosure regarding the Merger or any
of the other transactions contemplated by this Agreement unless (a) Parent shall
have approved such disclosure or (b) the Company shall have been advised by its
outside legal counsel that such disclosure 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 of Exhibit C.
 
     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 Gray Cary Ware & Freidenrich LLP tax representation letters in
customary form. Parent, Merger Sub and the Company shall each confirm to Cooley
Godward LLP and to Gray Cary Ware & Freidenrich LLP 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 representations 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 Gray Cary Ware & Freidenrich
LLP, 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. The parties hereto
shall report the Merger as a reorganization within the meaning of Section 368(a)
of the Code, and neither Parent, Merger Sub nor the Company shall take any
action prior to or following the Closing that would reasonably be expected to
cause the Merger to fail to qualify as a reorganization.
 
     5.12  Letter of the Company's Accountants. The Company shall use all
reasonable efforts to cause to be delivered to Parent and the Company a
"comfort" letter prepared by Arthur Andersen LLP in accordance with Statement of
Auditing Standards No. 72 "Letters For Underwriters and Certain Other Requesting
Parties," subject to receipt by Arthur Andersen LLP of a customary
representation letter from Parent, 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 and the Company), that
is customary in scope and substance for "comfort" 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 to be approved for listing as of
the Effective Time (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 on or prior to the Closing
the resignation of each officer and director from positions as an officer and
director of each of the Acquired Corporations (it being understood that such
resignations shall not
                                       35
<PAGE>   160
 
constitute a voluntary or an "Involuntary Termination" under the Change of
Control Agreements and shall not effect in any manner any rights of any officer
of the Company or any of the Company's obligations under the Change of Control
Agreements).
 
     5.15  Termination of 401(k) Plan. To the extent requested by Parent, the
Company shall ensure that its 401(k) Savings and Retirement Plan shall be
terminated immediately prior to the Effective Time.

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 are not reasonably expected to
result in, a Material Adverse Effect on the Acquired Corporations (it being
understood 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

Agreement (except that any representation or warranty that specifically refers
to "the date of this Agreement," "the date hereof" or any other date other than
the Closing Date speaks as of such date) shall be accurate in all respects as of
the Closing Date as if made on and as of the Closing Date, 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 are not reasonably expected to result in, a Material Adverse
Effect on the Acquired Corporations (it being understood 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

Stock at the Effective Time in accordance with Section 1.8(a)(i) shall represent
on conversion of such shares into Company Common Stock no more than 7% of the
number of shares of Company Common Stock outstanding immediately prior to the
Effective Time.
 
     6.5  Consents. All Consents required to be obtained in connection with the
Merger and the other transactions contemplated by this Agreement shall have been
obtained and shall be in full force and effect, except where the failure to

Effect on the Acquired Corporations.

     concerning the Acquired Corporations or any of the stockholders or
     affiliates of the Acquired Corporations that could preclude the Company

          (i) the written resignations of all officers and directors from
     positions as an officer and director of each of the Acquired Corporations
     effective as of the Effective Time (it being understood that such
     resignations shall not constitute a voluntary or an "Involuntary
     Termination" under the Change of Control Agreements and shall not effect in
     any manner any rights of any officer of the Company or any of the Company's
     obligations under the Change of Control Agreements).
 
     6.7  No Material Adverse Change. There shall have been no material adverse
change in the business, condition, assets, liabilities, operations or results of
operations of the Acquired Corporations since the date of this Agreement (it

size, (f) a
                                       37
<PAGE>   162

     subsequent date (as if made on such subsequent date), or if any of the
     Company's covenants contained in this Agreement shall have been breached in
     any material respect; provided, however, that Parent may not terminate this
     Agreement under this Section 8.1(f) (i) on account of an inaccuracy in the
     Company's representations and warranties that is curable by the Company or

     Company unless the Company fails to cure such inaccuracy or breach within

     breach; or (ii) if such inaccuracy or breach (considered in the aggregate
     with all other inaccuracies or breaches) would not result in a failure of

     Parent's representations and warranties that is curable by Parent or on
     account of a breach of a covenant by Parent that is curable by Parent
     unless Parent fails to cure such inaccuracy or breach within 30 days after
     receiving written notice from the Company of such inaccuracy or breach; or
     (ii) if such inaccuracy or breach (considered in the aggregate with all
     other inaccuracies or breaches) would not result in a failure of the
     conditions set forth in Section 7.1 hereof).
 
     8.2  Effect of Termination. In the event of the termination of this
Agreement as provided in Section 8.1, this Agreement shall be of no further
force or effect (and, except as provided in this Section 8.2, there shall be no
liability or obligation hereunder on the part of any of the parties hereto or
their respective officers, directors, stockholders or Affiliates); provided,
however, that (i) this Section 8.2, Section 8.3 and Section 9 shall survive the
termination of this Agreement and shall remain in full force and effect, and

to Section 8.1(d) and at or prior to the time of such termination an Acquisition
Proposal shall have been disclosed, announced, commenced, submitted or made (and
shall not have been publicly, absolutely and unconditionally withdrawn and
abandoned), or (ii) this Agreement is terminated by Parent pursuant to Section
8.1(e), then, in either such case, the Company shall pay to Parent, in cash at
the time specified in the next sentence, a nonrefundable fee in the amount of
$1,000,000 (the "Initial Termination Fee"). In the case of termination of this
Agreement by the Company pursuant to Section 8.1(d), the fee referred to in the
preceding sentence shall be paid by the Company prior to such termination, and
in the case of termination of this Agreement by Parent pursuant to Section
8.1(d) or Section 8.1(e), the fee referred to in the preceding sentence shall be
paid by the Company within two business days after such termination. If, within
360 days after the payment of the Initial Termination Fee, an Acquisition
Transaction (other than with Parent or one of Parent's Affiliates) is
consummated, or the Company enters into a definitive agreement with respect to
an Acquisition Transaction (other than with Parent or one of Parent's
Affiliates), the Company shall pay to Parent in cash an additional
                                       40

consummation of such Acquisition Transaction or the entering into of such
definitive agreement, whichever is earlier.
 
     (c) In no event shall the Company be required to pay any termination fee to
Parent pursuant to Section 8.3(b) if (i) prior to the applicable termination of
this Agreement, Parent was in material breach of its obligations under this
Agreement; (ii) prior to the applicable termination of this Agreement (and
promptly, and in any event, no more than two business days, after the Company
discovers any such material breach), the Company shall have advised Parent in
writing that Parent is in material breach of its obligations under this
Agreement; and (iii) prior to the applicable termination of this Agreement,
Parent shall not have substantially cured such material breach.
 
     SECTION 9. Miscellaneous Provisions
 
     9.1  Amendment. This Agreement may be amended with the approval of the
respective boards of directors of the Company and Parent at any time (whether
before or after the adoption and approval of this Agreement and the approval of
the Merger by the stockholders of the Company); provided, however, that after

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.

executed in several counterparts, each of which shall be deemed an original and
all of which shall constitute one and the same instrument.
 
     9.5  Applicable Law; Jurisdiction. This Agreement shall be governed by, and

action or suit.
 
     9.8  Assignability. This 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
Agreement nor any of the Company's rights hereunder may be assigned by the
Company without the prior written consent of Parent, and any attempted
assignment of this Agreement or any of such rights by the Company without such
consent shall be void and of no effect. Nothing in this Agreement, express or
implied, is intended to or shall confer upon any Person any right, benefit or
remedy of any nature whatsoever under or by reason of this Agreement.

                              AFFILIATE AGREEMENT
 
     THIS AFFILIATE AGREEMENT ("Affiliate Agreement") is being executed and
delivered as of October 12, 1998 by                ("Stockholder") in favor of
and for the benefit of APPLIED MATERIALS, INC., a Delaware corporation
("Parent").
 
                                    RECITALS
 
     A. Stockholder is a stockholder of, and is an officer and/or director of,
Consilium, Inc., a Delaware corporation (the "Company").
 
     B. Parent, the Company and Pennsylvania Acquisition Sub, Inc., a wholly
owned subsidiary of Parent ("Merger Sub"), have entered into an Agreement and
Plan of Merger and Reorganization dated as of October 12, 1998 (the
"Reorganization Agreement"), providing for the merger of Merger Sub into the
Company (the "Merger"). The Reorganization Agreement contemplates that, upon
consummation of the Merger, (i) holders of shares of the common stock of the
Company ("Company Common Stock") will receive shares of common stock of Parent
("Parent Common Stock") in exchange for their shares of Company Common Stock and
(ii) the Company will become a wholly owned subsidiary of Parent. It is
accordingly contemplated that Stockholder will receive shares of Parent Common
Stock in the Merger.
 
     C. Stockholder understands that the Parent Common Stock being issued in the
Merger will be issued pursuant to a registration statement on Form S-4, and that
Stockholder may be deemed an "affiliate" of the Company: (i) as such term is
defined for purposes of paragraphs (c) and (d) of Rule 145 under the Securities
Act of 1933, as amended (the "Securities Act"); and (ii) for purposes of
determining Parent's eligibility to account for the Merger as a "pooling of
interests" under Accounting Series Releases 130 and 135, as amended, of the
Securities and Exchange Commission (the "SEC"), and under other applicable
"pooling of interests" accounting requirements.

     1. Representations and Warranties of Stockholder. Stockholder represents
and warrants to Parent as follows:
 
          (a) Stockholder is the holder and "beneficial owner" (as defined in
     Rule 13d-3 under the Securities Exchange Act of 1934, as amended) of the
     number of shares of Company Common Stock set forth beneath Stockholder's
     signature on the signature page hereof (the "Company Shares"), and
     Stockholder has good and valid title to the Company Shares, free and clear
     of any liens, pledges, security interests, adverse claims, equities,
     options, proxies, charges, encumbrances or restrictions of any nature.
 
          (b) Stockholder has carefully read this Affiliate Agreement and, to
     the extent Stockholder felt necessary, has discussed with counsel the
     limitations imposed on Stockholder's ability to sell, transfer or otherwise
     dispose of the Company Shares and the shares of Parent Common Stock that
     Stockholder is to receive in the Merger (the "Parent Shares"). Stockholder
     fully understands the limitations this Affiliate Agreement places upon
     Stockholder's ability to sell, transfer or otherwise dispose of the Company
     Shares and the Parent Shares.
 
          (c) Stockholder understands that the representations, warranties and
     covenants set forth in this Affiliate Agreement will be relied upon by
     Parent and its counsel and accountants for purposes of determining Parent's
     eligibility to account for the Merger as a "pooling of interests" and for
     purposes of determining whether Parent should proceed with the Merger.
 
     2. Representation and Warranty of Parent. Parent represents and warrants to
Stockholder that it shall make available adequate current public information as
required by Rule 144(c) promulgated by the SEC under the Securities Act.

     other right to purchase any shares of capital stock of Parent, except by
     exercise of an option.
 
     (b) Notwithstanding the restrictions contained in Section 3(a), Stockholder
may transfer or otherwise reduce his risk relative to shares of Company Common
Stock or Parent Common Stock during the Restricted Period if (i) Parent, after
consulting with its independent accountants, determines that such transfer or
reduction in risk will not adversely affect the ability of Parent to account for
the Merger as a "pooling of interests," and (ii) Parent consents in writing to
such transfer or reduction in risk (it being understood that Parent will not
unreasonably withhold or delay such consent).
 
     (c) Stockholder agrees that Stockholder shall not effect any sale, transfer
or other disposition of any Parent Shares unless:

          (ii) such sale, transfer or other disposition is made in conformity

     have been met;
 
          (iii) counsel reasonably satisfactory to Parent shall have advised
     Parent in a written opinion letter (reasonably satisfactory in form and
     content to Parent), upon which Parent may rely, that such sale, transfer or
     other disposition will be exempt from registration under the Securities
     Act; or
 
          (iv) an authorized representative of the SEC shall have rendered
     written advice to Stockholder to the effect that the SEC would take no
     action, or that the staff of the SEC would not recommend that the SEC take
     action, with respect to such sale, transfer or other disposition, and a
     copy of such written advice and all other related communications with the
     SEC shall have been delivered to Parent.

                            NONCOMPETITION AGREEMENT
 
     THIS NONCOMPETITION AGREEMENT (the "Noncompetition Agreement") is being
executed and delivered as of October 12, 1998, by           (the "Stockholder"),
in favor of and for the benefit of the following entities (the "Beneficiaries"):
APPLIED MATERIALS, INC., a Delaware corporation ("Parent"), CONSILIUM, INC., a
Delaware corporation (the "Company"), each entity affiliated with any of the
foregoing entities, and the successors and assigns of each of the foregoing
entities.
 
                                    RECITALS
 
     A. As a stockholder, an employee and a director of the Company, the
Stockholder has obtained extensive and valuable knowledge and information
concerning the business of the Company (including confidential information
relating to the operations, assets, contracts, customers, personnel, plans and
prospects of the Company).
 
     B. Pursuant to an Agreement and Plan of Merger and Reorganization dated as
of October 12, 1998, among Parent, Pennsylvania Acquisition Sub, Inc. ("Merger
Sub") and the Company (the "Reorganization Agreement"), Merger Sub is expected
to merge with and into the Company (the "Merger") and the Company is expected to
become a wholly owned subsidiary of Parent.
 
     C. In connection with the Merger (and as a condition to the consummation of
the Merger), and to enable Parent to secure more fully the benefits of the
Merger, Parent has required that the Stockholder enter into this Noncompetition
Agreement.
 
     D. Parent, the Company and Parent's subsidiaries have conducted and are
expected to continue to conduct their businesses on a worldwide basis.
 
                                   AGREEMENT
 
     In order to induce Parent to consummate the transactions contemplated by
the Reorganization Agreement, and for other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the Stockholder,
intending to be legally bound, agrees as follows:
 
     1. Noncompetition.
 
     (a) During the period commencing on the Effective Date (as defined below)
and ending two years after the Effective Date (the "Noncompetition Period"), the
Stockholder shall not, and the Stockholder shall not permit any of his
affiliates to:
 
          (i) engage directly or indirectly in Competition (as defined below)
     anywhere in the world; or
 
          (ii) directly or indirectly be or become an officer, director,
     stockholder, owner, partner, employee, manager, agent, advisor or
     consultant of or to, or participate in the ownership, management,
     operation, control or financing of, any entity that engages directly or
     indirectly in Competition anywhere in the world.
 
     (b) Notwithstanding the restrictions contained in Section 1(a), the
Stockholder may[: (i)] own, as a passive investment, shares of capital stock of
a publicly-held corporation, if (A) such shares are actively traded on an
established national securities market in the United States, and (B) the number
of shares of such corporation's capital stock that are owned beneficially
(directly or indirectly) by the Stockholder and the number of shares of such
corporation's capital stock that are owned beneficially (directly or indirectly)
by the Stockholder's affiliates collectively represent less than 2% of the total
number of shares of such corporation's capital stock outstanding[; (ii) own
shares of, and may be an officer, director, employee, advisor and/or consultant
of or to, Vigilance Inc. ("Vigilance") so long as Vigilance does not engage
directly or indirectly in any Competition; provided, however, that to the extent
that the business engaged in by Vigilance as of the date
                                       D-1
<PAGE>   179
 
of this Noncompetition Agreement (as more particularly described in Exhibit A
hereto) constitutes Competition, Vigilance may continue to engage in such
business after the Merger without the Stockholder being deemed to have violated
Section 1(a); (iii) engage in general educational activities (including for
profit activities) relating to manufacturing execution systems so long as such
educational activities are not (A) related to a specific product; or (B)
provided to a competitor of any of the Acquired Corporations; and (iv) engage in
business or activities involving the design, development, manufacture, marketing
or distribution (whether by sale or license or otherwise) of software or
products that provide reporting, planning and scheduling or document management
functions in industries other than the semiconductor and flat panel display
industries.]
 
     (c) For purposes of Section 1, a person or entity shall be deemed to be
engaged in "Competition" if such person or entity is engaged directly or
indirectly in:
 
          (i) any business or activity involving (directly or indirectly) the
     (A) design, development, manufacture, marketing or distribution (whether by
     sale or license or otherwise) of manufacturing executions systems software
     or other software or products that track, correlate data with respect to
     and/or automate manufacturing operations in the semiconductor and flat
     panel display industries, (B) provision or performance of automated factory
     systems and software integration services in the semiconductor and flat
     panel display industries; or (C) provision or performance of services
     (including training, technical support or maintenance services) related to
     any of the products referred to in this clause "(i)" or in the last
     sentence of this Section 1(c);
 
          (ii) any other business or activity that is competitive with the
     business or activities engaged in by or proposed to be engaged in by the
     Company or any of its direct or indirect subsidiaries as of the Effective
     Date in the semiconductor or flat panel display industries; or
 
          (iii) any business or activity that is competitive with the business
     or activities of Parent, the Company, any of the Company's direct or
     indirect subsidiaries or any of Parent's other direct or indirect
     subsidiaries at any time after the Effective Date during which the
     Stockholder is an employee of, or consultant or advisor to, Parent, the
     Company or any of Parent's other direct or indirect subsidiaries.
 
Without limiting the generality of the foregoing (and subject to Section 1(b), a
person or entity shall be deemed to be engaged in Competition if such person or
entity designs, develops, manufactures, markets or distributes any software or
other product in the semiconductor or flat panel display industries that is
functionally similar to or that competes in any material respect with any of the
products in the Company's Workstream family of products or any of the proposed
products in the Company's proposed FAB300 family of products (or with any module
or component thereof which is proprietary to the Company).
 
     2. No Hiring or Solicitation of Employees; No Interference With
Customers. The Stockholder agrees that, during the Noncompetition Period, the
Stockholder shall not, and shall not permit any of his affiliates to:
 
          (a) hire any Specified Employee (as defined below); provided, however,
     that (i) the Stockholder may hire a particular Specified Employee if: (A)
     the Stockholder shall not have violated any of the restrictions contained
     in clause "(b)" of this Section 2 with respect to such Specified Employee;
     (B) such Specified Employee's employment relationship with the Acquired
     Corporations shall have terminated; and (C) such Specified Employee shall
     have accepted employment with a third party (other than an affiliate of the
     Stockholder) and shall have actually started working for such third party;
     [and (ii) the Stockholder may (with the prior written consent of Parent)
     hire a particular Specified Employee to work with the Stockholder at
     Vigilance;]
 
          (b) directly or indirectly, personally or through others, recruit,
     encourage, induce, attempt to induce, solicit or attempt to solicit (on the
     Stockholder's own behalf or on behalf of any other person or entity) any
     Specified Employee to leave his or her employment with Parent, the Company,
     any of the Company's direct or indirect subsidiaries or any of Parent's
     other direct or indirect subsidiaries; or
 
          (c) personally or through others, use any trade secret of Parent, the
     Company, any of the Company's direct or indirect subsidiaries or any of
     Parent's other direct or indirect subsidiaries, or any
 
                                       D-2
<PAGE>   180
 
     other improper means, to interfere or attempt to interfere with the
     relationship or prospective relationship of the Company, any of the
     Company's direct or indirect subsidiaries, Parent or any of Parent's direct
     or indirect subsidiaries, with any person or entity that is, was or is
     expected to become a customer or client of the Company, any of the
     Company's direct or indirect subsidiaries, Parent or any of Parent's direct
     or indirect subsidiaries.
 
For purposes of this Section 2, "Specified Employee" means any individual who is
or was an employee of any of the Acquired Corporations at any time between
October 12, 1998 and the Effective Date (or who becomes an employee of any of
the Acquired Corporations at any time during the Noncompetition Period).
 
     3. Representations and Warranties. The Stockholder represents and warrants,
to and for the benefit of the Beneficiaries, that: (a) he has full power and
capacity to execute and deliver, and to perform all of his obligations under,
this Noncompetition Agreement; and (b) neither the execution and delivery of
this Noncompetition Agreement nor the performance of this Noncompetition
Agreement will result directly or indirectly in a violation or breach of any
agreement or obligation by which the Stockholder or any of his affiliates is or
may be bound.
 
     4. Miscellaneous.
 
     (a) Specific Performance. The Stockholder agrees that (i) in the event of
any breach or threatened breach by the Stockholder of any covenant, obligation
or other provision set forth in this Noncompetition Agreement, the Beneficiaries

them), 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 Parent nor any other person or entity 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.
 
     (b) Non-Exclusivity. The rights and remedies of the Beneficiaries hereunder
are not exclusive of or limited by any other rights or remedies which the
Beneficiaries may have, whether at law, in equity, by contract or otherwise, all
of which shall be cumulative (and not alternative). Without limiting the

hereunder, and the obligations and liabilities of the Stockholder hereunder, are
in addition to their respective rights, remedies, obligations and liabilities
under the law of unfair competition, under laws relating to misappropriation of
trade secrets, under other laws and common law requirements and under all
applicable rules and regulations. Nothing in this Noncompetition Agreement shall
limit any of Parent's or the Stockholder's obligations, or the rights or
remedies of any of the Beneficiaries, under the Reorganization Agreement; and
nothing in the Reorganization Agreement shall limit any of Parent's or the
Stockholder's obligations, or any of the rights or remedies of any of the
Beneficiaries, under this Noncompetition Agreement. No breach on the part of
Parent or any other party of any covenant or obligation contained in the
Reorganization Agreement or any other agreement shall limit or otherwise affect
any right or remedy of any of the Beneficiaries under this Noncompetition
Agreement.

with the undersigned's employment or other relationship with the Company or any
of its direct or indirect subsidiaries; provided, however, that the undersigned
is not releasing the undersigned's rights, if any:
 
          (i) under the Reorganization Agreement;
 
          (ii) under that certain Change of Control Agreement dated
                         , 19  between the Company and the undersigned (the
     "Change of Control Agreement");
 
          (iii) under that certain Indemnification Agreement dated
                         , 19  between the Company and the undersigned (or under
     the indemnification provisions contained in the Company's Certificate of
     Incorporation or Bylaws);
 
          (iv) under those certain stock option agreements referred to in
     Exhibit A hereto);

        settlement with the debtor."
 
The undersigned also hereby waives the benefits of, and any rights the
undersigned may have under, any statute or common law principle of similar
effect in any jurisdiction.
 
     4. Assumption of Obligations under Change of Control Agreement. In

assumes the obligations of the Company under the Change of Control Agreement and
agrees to perform such obligations in the same manner and to the same extent as
the Company would be required to perform such obligations.
 
     5. Miscellaneous. This letter shall be governed by, and construed in
accordance with, the laws of the State of California, regardless of the laws
that might otherwise govern under applicable principles of conflicts of laws. If
any legal action or other legal proceeding relating to this letter or the
enforcement of any provision of this letter is brought against any party hereto,
the prevailing party shall be entitled to recover reasonable attorneys' fees,
costs and disbursements (in addition to any other relief to which the prevailing
party may be entitled). This letter and the agreements referred to herein set
forth the entire understanding of the parties relating to the subject matter
hereof and supersede all prior agreements and understandings among or between
any of the parties relating to the subject matter hereof.

the "Exchange Ratio". The Exchange Ratio shall be equal to a fraction, (i) the
numerator of which shall be equal to $5.50, and (ii) the denominator of which
shall be equal to the Parent Average Stock Price (as defined in the Agreement);
provided, however, that if the Parent Average Stock Price is equal to or less
than $30.25, then the Exchange Ratio shall be 0.182, and if the Parent Average
Stock Price is equal to or greater than $33.43, then the Exchange Ratio shall be
0.165. The Exchange Ratio is subject to adjustment, as provided in the
Agreement, if the Fully-Diluted Number of Shares (as defined in the Agreement)
exceeds 12,798,447. The Merger is intended to be a tax-free reorganization
within the meaning of Section 368(a) of the United States Internal Revenue Code
of 1986, as amended, and to be accounted for as a pooling of interests pursuant
to Opinion No. 16 of the Accounting Principles Board. The terms and conditions
of the above described Merger are more fully detailed in the Agreement.
 
     You have requested our opinion as to whether the Exchange Ratio is fair,
from a financial point of view, to Consilium shareholders.
 
     Broadview focuses on providing merger and acquisition advisory services to
information technology ("IT") companies. In this capacity, we are continually
engaged in valuing such businesses, and we maintain an extensive database of IT
mergers and acquisitions for comparative purposes. We will receive a fee from
Consilium upon delivery of this opinion.
 
     In rendering our opinion, we have, among other things:
 
      (1) reviewed the terms of the Agreement and the associated schedules
          thereto in the form of the draft dated October 8, 1998 furnished to us
          by Cooley Godward LLP on October 9, 1998 (which, for the purposes of
          this opinion, we have assumed, with your permission, to be identical
          in all material respects to the agreement to be executed);
 
      (2) reviewed Consilium's Form 10-K for its fiscal years ended October 31,
          1996 and 1997, including the audited financial statements included
          therein, and Consilium's Form 10-Q for the three months ended July 31,
          1998, including the unaudited financial statements included therein;
 
      (3) reviewed quarterly financial projections for Consilium for its fiscal
          years ending October 31, 1998, 1999 and 2000 prepared and provided to
          us by Consilium management;
 
      (4) participated in discussions with Consilium management concerning the
          operations, business strategy, financial performance and prospects for
          Consilium;
 
                                        1
<PAGE>   187
 
      (5) discussed with Consilium management its view of the strategic
          rationale for the Merger;
 
      (6) reviewed the reported closing prices and trading activity for
          Consilium Common Stock;
 
      (7) compared certain aspects of the financial performance of Consilium
          with public companies we deemed comparable;
 
      (8) analyzed available information, both public and private, concerning
          other mergers and acquisitions we believe to be comparable in whole or
          in part to the Merger;
 
      (9) reviewed Applied Material's annual report and Form 10-K for its fiscal
          years ended October 27, 1996 and October 26, 1997, including the
          audited financial statements included therein, and Applied Materials'
          Form 10-Q for the three months ended July 26, 1998, including the
          unaudited financial statements included therein;
 
     (10) participated in discussions with Applied Materials management
          concerning the operations, business strategy, financial performance
          and prospects for Applied Materials;
 
     (11) discussed with Applied Materials management its view of the strategic
          rationale for the Merger;
 
     (12) review the reported closing prices and trading activity for Applied
          Materials Common Stock;
 
     (13) compared certain aspects of the financial performance of Applied
          Materials with public companies we deemed comparable;
 
     (14) considered the total number of shares of Applied Materials Common
          Stock outstanding and the average weekly trading volume of Applied
          Materials Common Stock;
 
     (15) reviewed recent equity analyst reports covering Consilium and Applied
          Materials;
 
     (16) analyzed the anticipated effect of the Merger on the future financial
          performance of the consolidated entity; and
 
     (17) conducted other financial studies, analyses and investigations as we
          deemed appropriate for purposes of this opinion.
 
     In rendering our opinion, we have relied, without independent verification,
on the accuracy and completeness of all the financial and other information
(including without limitation the representations and warranties contained in
the Agreement) that was publicly available or furnished to us by Consilium or
Applied Materials. With respect to the financial projections examined by us, we
have assumed that they were reasonably prepared and reflected the best available
estimates and good faith judgments of the management of Consilium as to the
future performance of Consilium. We have neither made nor obtained an
independent appraisal or valuation of any of Consilium's assets. We have not
reviewed any internal financial projections prepared by Applied Materials
management as such projections have not been made available to us.
 
     Based upon and subject to the foregoing, we are of the opinion that the
Exchange Ratio is fair, from a financial point of view, to Consilium
shareholders.
 
     For purposes of this opinion, we have assumed that neither Consilium nor
Applied Materials is currently involved in any material transaction other than
the Merger and those activities undertaken in the ordinary course of conducting
their respective businesses. Our opinion is necessarily based upon market,
economic, financial and other conditions as they exist and can be evaluated as
of the date of this opinion, and any change in such conditions may impact this
opinion. We express no opinion as to the price at which Applied Materials Common
Stock will trade at any time.

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     The Delaware General Corporation Law provides, in substance, that Delaware
corporations shall have the power, under specified circumstances, to indemnify
their directors, officers, employees and agents in connection with actions,
suits or proceedings brought against them by third parties and in connection
with actions or suits by or in the right of the corporation, by reason of the
fact that they were or are such directors, officers, employees and agents,
against expenses (including attorney's fees) and, in the case of actions, suits
or proceedings brought by third parties, against judgments, fines and amounts
paid in settlement actually and reasonably incurred in any action, suit or
proceeding.
 
     The Registrant's Certificate of Incorporation provides for indemnification
of the Registrant's directors, officers, employees and other agents to the
fullest extent permitted by the Delaware General Corporation Law.
 
     Pursuant to the merger agreement, all rights to indemnification existing in
favor of the persons serving as directors or officers of Consilium as of the
date of the merger agreement for acts and omissions occurring prior to the
effective time of the merger, as provided in Consilium's Bylaws (as in effect as
of the date of the merger agreement) and as provided in the indemnification
agreements between Consilium and said directors and officers (as in effect as of
the date of the merger agreement), shall survive the merger and the Registrant
shall cause the Surviving Corporation to perform all of its obligations arising
thereunder for a period of not less than five years from the effective time of
the merger. The Merger agreement also provides that from the effective time of
the merger until the fifth anniversary of the date on which the effective time
of the merger occurs, the Registrant will cause the Surviving Corporation to
maintain in effect, for the benefit of the persons serving as directors and
officers of Consilium as of the date of the Merger agreement with respect to
acts or omissions occurring prior to the effective time of the merger, the
existing policy of directors' and officers' liability insurance maintained by
Consilium as of the date of the Merger 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 an annual premium for the
Existing Policy (or for any substitute policies) in excess of $168,750. The
merger agreement further provides that in the event any future annual premium
for the Existing Policy (or any substitute policies) exceeds $168,750, 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 $168,750.

ITEM 22. UNDERTAKINGS.
 
     (1) The Registrant hereby undertakes to respond to requests for information
that is incorporated by reference into the Proxy Statement/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.
 
     (2) The Registrant hereby undertakes 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.
 
     (3) The undersigned Registrant hereby undertakes 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 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to 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.
 
     (4) Insofar as indemnification for liabilities arising under the Securities
Act of 1933, as amended (the "Act") may be permitted to directors, officers and
controlling persons of the Registrant pursuant to the Certificate of
Incorporation, as amended, (the "Certificate of Incorporation") and the Bylaws,
as amended, (the "Bylaws") of the Registrant and the Delaware General
Corporation Law, 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 of 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.
 
     (5)(A) The undersigned Registrant hereby undertakes as follows: 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.
 
     (B) The Registrant undertakes that every prospectus: (i) that is filed
pursuant to paragraph (A) immediately preceding, or (ii) that purports to meet
the requirements of Section 10(a)(3) of the Act and is used in connection with
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 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.

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 the certain Agreement and Plan of Merger and
Reorganization, dated as of October 12, 1998, by and among the Company,
Pennsylvania Acquisition Sub, Inc., a Delaware corporation and a wholly-owned
subsidiary of the Company ("Merger Sub"), and Consilium, Inc., a Delaware
corporation ("Consilium"). 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 2,329,318 shares of the Company's common stock, $0.001 par value per share
("Common Stock"), 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 October 12,
1998, (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

October 28, 1998

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 Merger and Reorganization dated as of October 12, 1998
(the "Reorganization Agreement") by and among Applied Materials, Inc., a
Delaware corporation ("Parent"), Pennsylvania Acquisition Sub, Inc., a Delaware
corporation and wholly-owned subsidiary of Parent ("Merger Sub"), and Consilium,
Inc., a Delaware 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 consummation 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;

<PAGE>   2

Applied Materials, Inc.
October 28, 1998
Page Two


     (b)  All representations, warranties and statements made or agreed to by
Parent, Merger Sub and the Company, their managements, 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 October 28, 1998 rendered by Gray Cary Ware &
Freidenrich LLP 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.

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 "Material Federal
Income Tax Consequences" in the Proxy Statement included in the Registration
Statement and to the reproduction and filing of this opinion as an exhibit to
the Registration Statement.

Sincerely,



/s/ Webb B. Morrow III

Consilium, Inc.
485 Clyde Avenue
Mountain View, CA  94043

Ladies and Gentlemen:

This opinion is being delivered to you in accordance with the requirements of
Item 601(b)(8) of Regulation S-K under the Securities Act of 1933, as amended,
in connection with the filing of a registration statement on Form S-4 of a Proxy
Statement/Prospectus (the "Registration Statement") pursuant to the Agreement
and Plan of Merger and Reorganization dated as of October 12, 1998 (the
"Reorganization Agreement") by and among Applied Materials, Inc., a Delaware
corporation ("Acquiror"), Pennsylvania Acquisition Sub, Inc., a Delaware
corporation and a wholly-owned subsidiary of Acquiror ("Merger Sub") and
Consilium, Inc., a Delaware corporation (the "Company"). Pursuant to the
Reorganization Agreement, Merger Sub will merge with and into the Company (the
"Merger").

Unless otherwise defined, capitalized terms referred to herein 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 legal counsel to the Company in connection with the preparation
and execution of the Reorganization Agreement. 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 schedules and exhibits
thereto): (1) the Reorganization Agreement; (2) representations and warranties
made to us by Acquiror, Merger Sub and the Company (the "Tax Representation
Letters"); and (3) such other instruments and documents related to the
formation, organization and operation of Acquiror, Merger Sub and the Company or
to the consummation of the Merger and the transactions contemplated thereby as
we have deemed necessary or appropriate.

In connection with rendering this opinion, we have assumed or obtained
representations (and are relying thereon, without any independent investigation
or review thereof) that:

<PAGE>   2

Consilium, Inc.
October 28, 1998
Page Two


     1.   Original documents (including signatures) are authentic, documents
submitted to us as copies conform to the original documents, and there has been
(or will be by the Effective Time of the Merger) due execution and delivery of
all documents where due execution and delivery are prerequisites to
effectiveness thereof;

     2.   Any representation or statement made "to the best of knowledge" or
similarly qualified is correct without such qualification. As to all matters in
which a person or entity making a representation referred to above has
represented that such person or entity either is not a party to, does not have,
or is not aware of, any plan or intention, understanding or agreement, there is
in fact no such plan, intention, understanding or agreement;

     3.   All statements, descriptions and representations contained in any of
the documents referred to herein or otherwise made to us (including, but not
limited to the Tax Representation Letters) are true and correct as of the date
hereof and at the Effective Time, and no actions have been (or will be) taken
which are inconsistent with such statements, descriptions and representations;

     4.   The Merger will be consummated in accordance with the Reorganization
Agreement (and without any waiver, breach or amendment of any of the material
provisions thereof), will be effective under the applicable state law, and will
be reported by Acquiror and the Company on their respective federal income tax
returns in a manner consistent with the opinion set forth below; and

     5.   An opinion of Cooley Godward LLP, counsel to Acquiror, substantially
identical in substance to this opinion, has been delivered and not 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:

     1.   For federal income tax purposes, the Merger will be constitute a
reorganization within the meaning of Section 368(a) of the Code; and

     2.   Subject to the foregoing and the fact that the discussion in the
Registration Statement under the heading "Material Federal Income Tax
Consequences" (the "Discussion") is a summary and does not purport to discuss
all possible United Stated federal income tax consequences of the Merger and
sets forth additional limitations, qualifications, assumptions and caveats, the
Discussion sets forth the material United States federal income tax consequences
of the Merger to holders of Consilium Common Stock who exchange such stock for
Applied Materials Common Stock pursuant to the Reorganization Agreement.

This opinion does not address the various state, local or foreign tax
consequences that may result

from the Merger or other transactions contemplated by the Reorganization
Agreement. In addition, no opinion is expressed as to any federal income tax
consequences 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 any transaction other than the Merger as described
in the Reorganization Agreement or to any transaction whatsoever, including the
Merger, if all the transactions described in the Reorganization Agreement are
not consummated in accordance with the terms of such Reorganization 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 at all relevant times. 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.

This opinion represents and is based upon our best judgment regarding the
application of 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 the
Internal Revenue Service is not precluded from successfully asserting a contrary
position. Furthermore, no assurance can be given that future legislative,
judicial or administrative changes, on either a prospective or retroactive
basis, would 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 federal income tax
laws.

This opinion has been delivered to you only for the purposes stated. It is
intended for the benefit of the Company and the stockholders of the Company and
may not be relied upon for any other purpose or by any other person or entity,
and may not be made available to any other person or entity without our prior
written consent. We hereby consent, however, to the use of this opinion as an
exhibit to the Registration Statement and further consent to the use of our name
wherever appearing in the Registration Statement, including the Proxy
Statement/Prospectus constituting a part thereof, and any amendments thereto.

this Voting Agreement, and each part of each provision of this Voting Agreement
is separable from every other part of such provision.

     8.4 ENTIRE AGREEMENT. This Voting Agreement, the Proxy and any other
documents delivered by the parties in connection herewith constitute the entire
agreement between the parties with respect to the subject matter hereof and

assigns. Without limiting any of the restrictions set forth in Section 2 or

Proxy was not performed in accordance with its specific terms or was otherwise
breached. Stockholder agrees that, in the event of any breach or threatened
breach by Stockholder of any covenant or obligation contained in this Voting
Agreement or in the Proxy, Parent shall be entitled (in


                                       6

<PAGE>   7

addition to any other remedy that may be available to it, including monetary
damages) to seek and obtain (a) a decree or order of specific performance to
enforce the observance and performance of such covenant or obligation, and (b)
an injunction restraining such breach or threatened breach. Stockholder further
agrees that neither Parent nor any other Person shall be required to obtain,
furnish or post any bond or similar instrument in connection with or as a
condition to obtaining any remedy referred to in this Section 8.6, and
Stockholder irrevocably waives any right he may have to require the obtaining,
furnishing or posting of any such bond or similar instrument.

     8.7 NON-EXCLUSIVITY. The rights and remedies of Parent under this Voting
Agreement are not exclusive of or limited by any other rights or remedies which

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.

and federal court located in the County of Santa Clara, California (and each
appellate court located in the State of California), in connection with any such
legal proceeding; (ii) agrees that service of any process, summons, notice or
document by U.S. mail addressed to him at the address set forth in Section 8.2
shall constitute effective service of such process, summons, notice or document
for purposes of any such legal proceeding; (iii) agrees that each state and
federal court located in the County of Santa Clara, California, shall be deemed
to be a convenient forum; and (iv) agrees not to assert (by way of motion, as a
defense or otherwise), in any such legal proceeding commenced in any state or
federal court located in the County of Santa Clara, California, any claim that
Stockholder is not subject personally to the jurisdiction of such court, that
such legal proceeding has been brought in an inconvenient forum, that the venue
of such proceeding is improper or that this Voting Agreement or the subject
matter of this Voting Agreement may not be enforced in or by such court. Nothing
contained in this Section 8.8(b) shall be deemed to limit or otherwise affect

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

     The undersigned stockholder of Consilium, Inc., a Delaware corporation (the

(ii) any and all other shares of capital stock of the Company which the
undersigned may acquire on or after the date hereof. (The shares of the capital

Reorganization, dated as of the date hereof, among Parent, Merger Sub 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

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).

     If any provision of this proxy or any part of any such provision is held
under any circumstances to be invalid or unenforceable in any jurisdiction, then
(a) such provision or part thereof shall, with respect to such circumstances and
in such jurisdiction, be deemed amended to conform to applicable laws so as to
be valid and enforceable to the fullest possible extent, (b) the invalidity or
unenforceability of such provision or part thereof under such circumstances and
in such jurisdiction shall not affect the validity or enforceability of such
provision or part thereof under any other circumstances or in any other
jurisdiction, and (c) the invalidity or unenforceability of such provision or
part thereof shall not affect the validity or enforceability of


                                       1

Reorganization Agreement or the effective time of the Merger.
