ITEM 5.  OTHER EVENTS.

        On October 12, 1998, Consilium, Inc. (the "Company"), Applied 
Materials, Inc. ("Applied Materials") and Pennsylvania Acquisition Sub, Inc.
("Sub") entered into an Agreement and Plan of Merger and Reorganization (the
"Agreement") pursuant to which Applied Materials is to acquire the Company in a
stock-for-stock merger. As more fully described in the Agreement and the joint
press release, both of which are filed herewith, Sub will merge with and into
the Company and each share of the Company's stock will be exchanged for between
0.182 and 0.165 of a share of Applied Material's common stock, with the actual
ratio being based upon Applied Material's average stock closing price during a
specified period prior to the meeting of the Company's stockholders to vote on
the merger. The merger, which will be accounted for as a pooling-of-interests,
is subject to, among other things, regulatory approval and approval of the stock
of the Company. Certain stockholders of the Company have already entered into
voting agreements in support of the merger.

              (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

                                      2.
<PAGE>
 
              (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.


                                      3.
<PAGE>
 
          (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, 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

                                      4.
<PAGE>
 
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
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).

                                      5.
<PAGE>
 
          (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) such Company Common Stock had been converted into the right to
    receive Parent Common Stock in accordance with Section 1.5(a)(iv), 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

                                      6.
<PAGE>
 
    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 

                                      7.
<PAGE>
 
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 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,
<PAGE>
 
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.

     SECTION 2.  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

     The Company represents and warrants to Parent and Merger Sub as follows:

          2.1  DUE ORGANIZATION; SUBSIDIARIES; ETC.

               (A)  The Company has no Subsidiaries, except for the Entities
identified in Part 2.1(a)(i) of the Company Disclosure Schedule; and neither the
Company nor any of the other Entities identified in Part 2.1(a)(i) of the
Company Disclosure Schedule owns any capital stock of, or any equity interest of
any nature in, any other Entity, other than the Entities identified in Part
2.1(a)(ii) of the Company Disclosure Schedule. (The Company and each of its
Subsidiaries are referred to collectively in this Agreement as the "Acquired
Corporations.") None of the Acquired Corporations has agreed or is obligated to
make, or is bound by any Contract under which it may become obligated to make,
any future investment in or capital contribution to any other Entity. None of
the Acquired Corporations has, at any time, been a general partner of, or has
otherwise been liable for any of the debts or other obligations of, any general
partnership, limited partnership or other Entity.

               (B)  Each of the Acquired Corporations is a corporation duly
organized, validly existing and in good standing under the laws of the
jurisdiction of its incorporation and has all necessary power and authority: (i)
to conduct its business in the manner in which its business is currently being
conducted; (ii) to own and use its assets in the manner in which its

                                      9.
<PAGE>
 
assets are currently owned and used; and (iii) to perform its obligations under
all Contracts by which it is bound.

          (C) Each of the Acquired Corporations is qualified to do business as a
foreign corporation, and is in good standing, under the laws of all
jurisdictions where the nature of its business requires such qualification and
where the failure to be so qualified would reasonably be expected to have a
Material Adverse Effect on the Acquired Corporations.

     2.2  CERTIFICATE OF INCORPORATION AND BYLAWS.  The Company has
delivered to Parent accurate and complete copies of the certificate of
incorporation, bylaws and other charter and organizational documents of the
respective Acquired Corporations, including all amendments thereto.

     2.3  CAPITALIZATION, ETC.

          (A) The authorized capital stock of the Company consists of:  (i)

issued and are outstanding as of September 30, 1998; and (ii) 4,000,000 shares
of Preferred Stock, $.01 par value per share, of which 3,000 shares are
designated as "Series A Convertible Preferred Stock" (the "Company Preferred
Stock"), of which 3,000 shares are issued and outstanding as of the date of this
Agreement.  The maximum number of shares of Company Common Stock issuable upon
the conversion of all outstanding shares of Company Preferred Stock is
1,538,462.  The Company has not repurchased any shares of its capital stock
pursuant to the stock repurchase program announced by the Company on August 13,
1998 and does not hold any shares of its capital stock in its treasury.  All of
the outstanding shares of Company Common Stock and Company Preferred Stock have
been duly authorized and validly issued, and are fully paid and nonassessable.
As of the date of this Agreement, there are no shares of Company Common Stock or
Company Preferred Stock held by any of the other Acquired Corporations.  Except
as set forth in Part 2.3(a)(i) of the Company Disclosure Schedule: (i) none of
the outstanding shares of Company Common Stock or Company Preferred Stock is
entitled or subject to any preemptive right, right of participation, right of
maintenance or any similar right created by the Company or imposed under
applicable law with respect to capital stock of the Company; (ii) none of the
outstanding shares of Company Common Stock or Company Preferred Stock is subject
to any right of first refusal in favor of the Company; and (iii) there is no
Acquired Corporation Contract relating to the voting or registration of, or
restricting any Person from purchasing, selling, pledging or otherwise disposing
of (or granting any option or similar right with respect to), any shares of
Company Common Stock or Company Preferred Stock.  None of the Acquired
Corporations is under any obligation, or is bound by any Contract pursuant to
which it may become obligated, to repurchase, redeem or otherwise acquire any
outstanding shares of Company Common Stock or Company Preferred Stock.  As of
September 30, 1998, the aggregate dollar amount of dividends accrued with
respect to all outstanding shares of Company Preferred Stock is $270,000.  The
Company has never paid any dividends with respect to any Company Preferred
Stock.

          (B) As of September 30, 1998: (i) 1,937,797 shares of Company Common
Stock are subject to issuance pursuant to outstanding options to purchase shares
of Company Common Stock; (ii) 108,059 shares of Company Common Stock are
reserved for future issuance pursuant to the Company's Employee Stock Purchase
Plan (the "ESPP"); and (iii) 250,000 shares of Company Common Stock are reserved
for future issuance pursuant to the Company Warrants.  (Stock options granted by
the Company pursuant to the Company's stock option plans and otherwise are

as of the date of this Agreement; and (vii) the date on which such Company
Option expires.  The Company has delivered to Parent accurate and complete
copies of all stock option plans pursuant to which the Company has ever granted
stock options, the forms of all stock option agreements evidencing such options
and the actual Change of Control Agreements with each employee of the Company
who is a party to a Change of Control Agreement with the Company (the "Change of
Control Agreements").  The Company has delivered to Parent accurate and complete
copies of the Company Warrants.  Except as set forth in Part 2.3(b) of the
Company Disclosure Schedule, the exercise price of the warrants to purchase
shares of Company Common Stock held by Imperial Bancorp is $3.98 per share, and
the exercise price of the warrants to purchase shares of Company Common Stock
held by Evelyn Hilton and Thomas Camarda is $6.33 per share.

          (C) Except as set forth in Section 2.3(b) or as reserved for future
issuance under the ESPP, there is no: (i) outstanding subscription, option,
call, warrant or right (whether or not currently exercisable) to acquire any
shares of the capital stock or other securities of the Company; (ii) outstanding
security, instrument or obligation that is or may become convertible into or
exchangeable for any shares of the capital stock or other securities of the
Company; (iii) stockholder rights plan (or similar plan commonly referred to as
a "poison pill") or Contract under which the Company is or may become obligated
to sell or otherwise issue any shares of its capital stock or any other
securities; or (iv) to the Knowledge of the Company, condition or circumstance
that may give rise to or provide a basis for the assertion of a claim by any
Person to the effect that such Person is entitled to acquire or receive any
shares of capital stock or other securities of the Company.

          (D) All outstanding shares of Company Common Stock, all outstanding
shares of Company Preferred Stock, all outstanding Company Options, all

commitment to create any Welfare Plan or any Pension Plan, or to modify or
change any existing Welfare Plan or Pension Plan (other than to comply with
applicable law) in a manner that would affect any current or former employee or
director of any of the Acquired Corporations.

                (G)  No Plan provides death, medical or health benefits (whether
or not insured) with respect to any current or former employee or director of
any of the Acquired Corporations after any termination of service of such
employee or director (other than (i) benefit coverage mandated by applicable
law, including coverage provided pursuant to Section 4980B of the Code, (ii)
deferred compensation benefits accrued as liabilities on the Unaudited Interim
Balance Sheet, and (iii) benefits the full cost of which are borne by current or
former employees or directors of any of the Acquired Corporations (or their
beneficiaries)).

                (H)  Except as set forth in Part 2.17(h) of the Company
Disclosure Schedule, with respect to any Plan constituting a group health plan
within the meaning of Section 4980B(g)(2) of the Code, the provisions of Section
4980B of the Code ("COBRA") have been complied with in all material respects.

                (I)  Except as set forth in Part 2.17(i) of the Company
Disclosure Schedule, to the Knowledge of the Company, each of the Plans has been
operated and administered in all material respects in accordance with applicable
Legal Requirements, including ERISA and the Code, each Legal Requirement
pursuant to which any of the Acquired Corporations is required to establish any
reserve or make any contribution for the benefit of any current or former
employee located in Korea, Singapore, Taiwan, India or any other foreign
jurisdiction and each other applicable foreign Legal Requirement.

                                      29.

                (J)  Each of the Plans intended to be qualified under Section
401(a) of the Code has received a favorable opinion letter from the Internal
Revenue Service, and the Company is not aware of any reason why any such
determination letter could be revoked.

                (K)  Except pursuant to the Change of Control Agreements or as
set forth in Part 2.17(k) of the Company Disclosure Schedule, neither the
execution, delivery or performance of this Agreement, nor the consummation of
the Merger or any of the other transactions contemplated by this Agreement, will
result in any bonus, golden parachute, severance or other payment or obligation
to any current or former employee or director of any of the Acquired
Corporations (whether or not under any Plan), or materially increase the
benefits payable or provided under any Plan, or result in any acceleration of
the time of payment, provision or vesting of any such benefits. Without limiting
the generality of the foregoing (and except pursuant to the Change of Control
Agreements or as set forth in Part 2.17(k) of the Company Disclosure Schedule),
the consummation of the Merger will not result in the acceleration of vesting of
any unvested Company Options.

                (L)  Part 2.17(l) of the Company Disclosure Schedule identifies
each employee of each of the Acquired Corporations as of the date of this
Agreement, and correctly reflects, in all material respects, the current salary
and any other compensation payable to such employee (including compensation
payable pursuant to bonus, deferred compensation or commission arrangements),
such employee's employer, date of hire and position and the principal office of
such employee. None of the Acquired Corporations is a party to any collective
bargaining contract or other Contract with a labor union involving any of its
employees. All of the employees of the Acquired Corporations are "at will"
employees.

                (M)  Part 2.17(m) of the Company Disclosure Schedule identifies
each employee of any of the Acquired Corporations who is not fully available to
perform work because of disability or other leave and sets forth the basis of
such disability (to the extent known by the Company) or leave and the
anticipated date of such employee's return to full service.

                (N)  Each of the Acquired Corporations is in compliance in all
material respects with all applicable Legal Requirements and Contracts relating
to employment, employment practices, wages, bonuses and terms and conditions of
employment, including employee compensation matters.

                (O)  Each of the Acquired Corporations has good labor relations,
and the Company has no knowledge of any facts indicating that (i) the
consummation of the Merger or any of the other transactions contemplated by this
Agreement will have a material adverse effect on the labor relations of any of
the Acquired Corporations, or (ii) any of the employees of any of the Acquired
Corporations intends to terminate his or her employment with such Acquired
Corporation.

          2.18  ENVIRONMENTAL MATTERS.  Each of the Acquired Corporations is in
compliance in all material respects with all applicable Environmental Laws,
which compliance includes the possession by each of the Acquired Corporations of
all permits and other Governmental Authorizations required of them under
applicable Environmental Laws, and

                                      30.
<PAGE>
 
compliance in all material respects with the terms and conditions thereof. To
the Knowledge of the Company, since January 1, 1996, none of the Acquired
Corporations has received any notice or other communication (in writing or
otherwise), whether from a Governmental Body, citizens group, employee or
otherwise, that alleges that any of the Acquired Corporations is not in
compliance in all material respects with any Environmental Law. To the Knowledge
of the Company, no current or prior owner of any property leased by any of the
Acquired Corporations has received any notice or other communication (in writing
or otherwise), whether from a Government Body, citizens group, employee or
otherwise, that alleges that such current or prior owner or any of the Acquired
Corporations is not in compliance in all material respects with any
Environmental Law. To the Knowledge of the Company (a) all property that is
leased to or used by the Company, and all surface water, groundwater and soil
associated with such property is free of any material environmental
contamination of any nature, (b) none of the property leased to or used by any
of the Acquired Corporations presently contains any underground storage tanks,
asbestos, equipment using PCBs or underground injection wells, and (c) none of
the property leased to or used by any of the Acquired Corporations presently
contains any septic tanks in which process wastewater or any Materials of
Environmental Concern have been disposed. To the Knowledge of the Company, no
Acquired Corporation has sent or transported, or arranged to send or transport,
any Materials of Environmental Concern to a site that, pursuant to any
applicable Environmental Law (i) has been placed on the "National Priorities
List" of hazardous waste sites or any similar state list, (ii) is otherwise
designated or identified as a potential site for remediation, cleanup, closure
or other environmental remedial activity, or (iii) is subject to a Legal
Requirement to take "removal" or "remedial' action as detailed in any applicable
Environmental Law or to make payment for the cost of cleaning up the site. (For
purposes of this Section 2.18:  (A) "Environmental Law" means any federal,
state, local or foreign Legal Requirement relating to pollution or protection of
human health from Materials of Environmental Concern or protection of the
environment (including ambient air, surface water, ground water, land surface or
subsurface strata), including any law or regulation relating to emissions,
discharges, releases or threatened releases of Materials of Environmental
Concern, or otherwise relating to the manufacture, processing, distribution,
use, treatment, storage, disposal, transport or handling of Materials of
Environmental Concern; and (B) "Materials of Environmental Concern" means
chemicals, pollutants, contaminants, wastes, toxic substances, petroleum and
petroleum products and any other substance that is regulated by any Governmental
Body with respect to the environment.)

          2.19  INSURANCE.  The Company has delivered to Parent a copy of all
material insurance policies and all material self insurance programs and
arrangements relating to the business, assets and operations of the Acquired
Corporations. Except as set forth in Part 2.19 of the Company Disclosure
Schedule, each of such insurance policies is in full force and effect. Since
January 1, 1996, none of the Acquired Corporations has received any notice or
other communication regarding any actual or possible (a) cancellation or
invalidation of any insurance policy, (b) refusal of any coverage or rejection
of any material claim under any insurance policy, or (c) material adjustment in
the amount of the premiums payable with respect to any insurance policy. Except
as set forth in Part 2.19 of the Company Disclosure Schedule, there is no
pending workers' compensation or other claim under or based upon any insurance
policy of any of the Acquired Corporations.

          2.20  TRANSACTIONS WITH AFFILIATES.  Except as set forth in the
Company SEC Reports, since the date of the Company's last proxy statement filed
with the SEC, no event has occurred that would be required to be reported by the
Company pursuant to Item 404 of Regulation S-K promulgated by the SEC. Part 2.20
of the Company Disclosure Schedule identifies each person who is (or who may be
deemed to be) an "affiliate" (as that term is used in Rule 145 under the
Securities Act) of the Company as of the date of this Agreement.

          2.21  LEGAL PROCEEDINGS; ORDERS.

                (A)  There is no pending Legal Proceeding, and (to the Knowledge
of the Company) no Person has threatened to commence any Legal Proceeding: (i)
that involves any of the Acquired Corporations or any of the assets owned or
used by any of the Acquired Corporations and that, if adversely determined,
would reasonably be expected to have a Material Adverse Effect on the Acquired
Corporations; or (ii) that challenges, or that may have the effect of
preventing, delaying, making illegal or otherwise interfering with, the Merger
or any of the other transactions contemplated by this Agreement. To the
Knowledge of the Company, no event has occurred, and no claim, dispute or other
condition or circumstance exists, that would reasonably be expected to, give
rise to or serve as a basis for the commencement of any such Legal Proceeding.

                (B)  There is no material order, writ, injunction, judgment or
decree to which any of the Acquired Corporations, or any of the assets owned or
used by any of the Acquired Corporations, is subject. To the Knowledge of the
Company, no officer or key employee of any of the Acquired Corporations is
subject to any order, writ, injunction, judgment or decree that prohibits such
officer or other key employee from engaging in or continuing any conduct,
activity or practice relating to the business of any of the Acquired
Corporations.

          2.22  AUTHORITY; INAPPLICABILITY OF ANTI-TAKEOVER STATUTES; BINDING
NATURE OF AGREEMENT.  The Company has the absolute and unrestricted right, power
and authority to enter into and to perform its obligations under this Agreement.
The board of directors of the Company (at a meeting duly called and held on
October 12, 1998) has (a) determined (pursuant to a unanimous vote of all
members of the board of directors of the Company) that the Merger is advisable
and fair and in the best interests of the Company and its stockholders, (b)
authorized and approved (pursuant to a unanimous vote of all members of the
board of directors of the Company) the execution, delivery and performance of
this Agreement by the Company and approved (pursuant to a unanimous vote of all
members of the board of directors of the Company) the Merger, (c) recommended
(pursuant to a unanimous vote of all members of the board of directors of the
Company) the approval of this Agreement and the Merger by the holders of Company
Common Stock and directed that this Agreement and the Merger be submitted for
consideration by the Company's stockholders at the Company Stockholders' Meeting
(as defined in Section 5.2), and (d) adopted (pursuant to a unanimous vote of
all members of the board of directors of the Company) a resolution having the
effect of causing the Company not to be subject to any state takeover law or
similar Legal Requirement that might otherwise apply to the Merger or any of the
other transactions contemplated by this Agreement. This Agreement constitutes
the legal, valid and binding obligation of the Company, enforceable

                                      32.
<PAGE>
 
against the Company in accordance with its terms, subject to (i) laws of general
application relating to bankruptcy, insolvency and the relief of debtors, and
(ii) rules of law governing specific performance, injunctive relief and other
equitable remedies.

          2.23  SECTION 203 OF THE DGCL NOT APPLICABLE.  As of the date hereof
and at all times on or prior to the Effective Time, the restrictions applicable
to business combinations contained in Section 203 of the DGCL are, and will be,
inapplicable to the execution, delivery and performance of this Agreement and to
the consummation of the Merger and the other transactions contemplated by this
Agreement. Prior to the execution of those certain Voting Agreements of even

the Company Disclosure Schedule, the Board of Directors of the Company approved
said Voting Agreements and the transactions contemplated thereby.

          2.24  INAPPLICABILITY OF SECTION 2115 OF CALIFORNIA CORPORATIONS CODE.

the Company), none of the Acquired Corporations has engaged, directly or
indirectly, in any discussions or negotiations with any other Person with
respect to any Acquisition Proposal.
     
          2.26  ACCOUNTING MATTERS.  To the Knowledge of the Company, neither
the Company nor any affiliate (as that term is used in Rule 145 under the
Securities Act) of any of the Acquired Corporations has taken or agreed to take,
or plans to take, any action that could prevent Parent from accounting for the
Merger as a "pooling of interests" in accordance with generally accepted
accounting principles, Accounting Principles Board Opinion No. 16 and all
published rules, regulations and policies of the SEC. Arthur Andersen LLP has
confirmed in a letter the date of this Agreement and addressed to the Company,
an executed copy of which has been delivered to Parent and
PricewaterhouseCoopers LLP, that (subject to the qualifications contained in
such letter) Arthur Andersen LLP's concurrence with the Company's management's
conclusion that the Company is 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.

          2.27  VOTE REQUIRED.  The affirmative vote of the holders of a
majority of the shares of Company Common Stock outstanding on the record date
for the Company Stockholders' Meeting (the "Required Company Stockholder Vote")
is the only vote of the holders of any class or series of the Company's capital

(with or without notice or lapse of time):

                (A)  contravene, conflict with or result in a violation of (i)
     any of the provisions of the certificate of incorporation, bylaws or other
     charter or organizational documents of any of the Acquired Corporations, or
     (ii) any resolution adopted by the stockholders, the board of directors or
     any committee of the board of directors of any of the Acquired
     Corporations;

                (B)  contravene, conflict with or result in a violation of any
     Legal Requirement, or give any Governmental Body or other Person the right
     to challenge the Merger or any of the other transactions contemplated by
     this Agreement or to exercise any remedy or obtain any relief under any
     order, writ, injunction, judgment or decree to which any of the Acquired

     or give any Person the right to (i) declare a default or exercise any
     remedy under any such Acquired Corporation Contract, (ii) accelerate the
     maturity or performance of any such Acquired Corporation Contract, or (iii)
     cancel, terminate or modify any term of such Acquired Corporation Contract;
     or

                (E)  result in the imposition or creation of any Encumbrance
     upon or with respect to any asset owned or used by any of the Acquired
     Corporations (except for minor liens that will not, in any case or in the

respect to such Acquisition Proposal, the Company may agree to pay additional
fees, commissions and other amounts to Broadview International LLC (in which
case, the Company will promptly advise Parent of the amount of such fees,

necessary action on the part of Parent and Merger Sub and their respective
boards of directors. This Agreement constitutes the legal, valid and binding

Merger Sub of the Merger will (a) conflict with or result in any breach of any
provision of the certificate of incorporation or bylaws of Parent or the
certificate of incorporation or bylaws of Merger Sub, (b) result in a default by
Parent or Merger Sub under any Contract to which Parent or Merger Sub is a
party, except for any default which has not had and will not have a Material
Adverse Effect on Parent, or (c) result in a violation by Parent or Merger Sub
of any order, writ, injunction, judgment or decree to which Parent or Merger Sub
is subject, except for any violation which has not had and will not have a
Material Adverse Effect on Parent. Except as may be required by the Securities
Act, the Exchange Act, state securities or "blue sky" laws, the DGCL, the HSR
Act and the NASD Bylaws (as they relate to the S-4 Registration Statement and
the Prospectus/Proxy Statement), Parent is not and will not be required to make

interests" in accordance with generally accepted accounting principles,
Accounting Principles Board Opinion No. 16 and all published rules, regulations
and policies of the SEC. Parent has received a letter dated the date of this

                                      37.
<PAGE>
 
Agreement, from PricewaterhouseCoopers LLP, a copy of which has been delivered

that the Merger should be treated 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.

Parent agrees not to unreasonably withhold or delay its consent to any of the
actions referred to in clause "(vi)" of this Section 4.2(b).

Without limiting any other provision of this Section 4.2(b), during the Pre-
Closing Period, the Company agrees to consult with Parent a reasonable period of

promptly notify Parent in writing of: (i) the discovery by the Company of any
event, condition, fact or circumstance that occurred or existed on or prior to
the date of this Agreement and that caused or constitutes a material inaccuracy
in any representation or warranty made by the Company in this Agreement; (ii)
any event, condition, fact or circumstance that occurs, arises or exists after
the date of this Agreement and that would cause or constitute a material
inaccuracy in any representation or warranty made by the Company in this
Agreement if (A) 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 (B) such event, condition, fact or circumstance had occurred,
arisen or existed on or prior to the date of this Agreement; (iii) any material
breach of any covenant or obligation of the Company; and (iv) any event,
condition, fact or circumstance that would make the timely satisfaction of any

the Company shall promptly advise Parent in writing of any Legal Proceeding or
material claim threatened, commenced or asserted against or with respect to any
of the Acquired Corporations. No notification given to Parent pursuant to this

                                      41.
<PAGE>
 
of the representations, warranties, covenants or obligations of the Company
contained in this Agreement.

          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 Acquisition Proposal, (ii) furnish any
information regarding any of the Acquired Corporations to any Person in
connection with or in response to an Acquisition Proposal, (iii) engage in
discussions or negotiations with any Person with respect to any Acquisition
Proposal, (iv) approve, endorse or recommend any Acquisition Proposal or (v)
enter into any letter of intent or similar document or any Contract
contemplating or otherwise relating to any Acquisition Transaction; PROVIDED,
HOWEVER, that prior to the 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

                                      42.
<PAGE>
 
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.

Agreement, Parent and the Company shall prepare and cause to be filed with the
SEC the Prospectus/Proxy Statement and Parent shall prepare and cause to be
filed with the SEC the Form S-4 Registration Statement, in which the
Prospectus/Proxy Statement will be included as a prospectus. PROVIDED, HOWEVER,
that notwithstanding anything to the contrary contained in this Section 5.1(a),
if (and to the extent) Parent so elects: (i) the Proxy Statement Prospectus
shall 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 Registration Statement effective under the Securities Act, all
amendments to the 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

                                      43.
<PAGE>
 
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 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

                                      44.
<PAGE>
 
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

                                      45.
<PAGE>
 
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 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

                                      46.
<PAGE>
 
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 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.

effectuate the Merger and make effective the other transactions contemplated by
this Agreement. Without limiting the generality of the foregoing, but subject to

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 

                                      48.
<PAGE>
 
Subsidiaries to discontinue offering any product or service, or to commit to
cause any of the Acquired Corporations to discontinue offering any product or
service; (iii) to license or otherwise make available, or cause any of its

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

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

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.

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

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

the Change of Control Agreements).

termination of this Agreement and shall remain in full force and effect, and
(ii) the termination of this Agreement shall not relieve any party from any
liability for any willful breach of any representation, warranty or covenant
contained in this Agreement.

          8.3  EXPENSES; TERMINATION FEES.

               (A) Except as set forth in this Section 8.3, all fees and
expenses incurred in connection with this Agreement and the transactions

expenses, whether or not the Merger is consummated; PROVIDED, HOWEVER, that
Parent and the Company shall share equally all fees and expenses, other than

Acquisition Proposal shall have been disclosed, announced, commenced, submitted
or made (and shall not have been publicly, absolutely and unconditionally

pursuant to Section 8.1(e), then, in either such case, the Company shall pay to

Fee, an Acquisition Transaction (other than with Parent or one of Parent's
Affiliates) is consummated, or the Company enters into a definitive agreement

Parent's Affiliates), the Company shall pay to Parent in cash an additional

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 

                                      57.

Agreement; and (iii) prior to the applicable termination of this Agreement,
Parent shall not have substantially cured such material breach.

                                   Applied Materials to Enter the Manufacturing
                                   Execution System Software Business with the 
                                          Acquisition of Consilium, Inc.

                                 SANTA CLARA, Calif., October 12, 1998 --
                                 Applied Materials, Inc. and Consilium, Inc.
                                 announced today that they had reached a
                                 definitive agreement for Applied Materials to
                                 acquire Consilium in a stock-for-stock merger.
                                 Each share of Consilium's stock will be
                                 exchanged for between 0.182 and 0.165 of a
                                 share of Applied Materials' common stock, with
                                 the actual ratio being based upon Applied
                                 Materials' average stock closing price during a
                                 specified period prior to the meeting of
                                 Consilium's stockholders to vote on the merger.
                                 The proposed acquisition would combine the
                                 strengths of the world's largest semiconductor
                                 equipment company with the leading independent
                                 supplier of integrated semiconductor and
                                 electronics manufacturing execution systems
                                 (MES) software and services.

                                 "As the company with the largest installed base
                                 of independent MES software, Consilium has
                                 established itself as a major force in
                                 providing semiconductor and electronics
                                 manufacturers with a way to optimize fab
                                 performance," said Sass Somekh, senior vice
                                 president,

                         Office of the President, Applied Materials. "We see a
                         wide range of synergies that this merger can offer to
                         extend our continued commitment to customers to improve
                         overall equipment effectiveness and total fab
                         productivity. This combination strengthens our primary
                         business objective to provide Total Solutions (TM) to
                         our customers that enhance their profitability."

                         "We believe that this merger represents a strategic
                         opportunity for both companies," said Larry Hootnick,
                         president and chief executive officer, Consilium, Inc.
                         "Combining our world-class software with Applied
                         Materials' expertise in semiconductor processing will
                         provide us with the momentum to move our advanced
                         technologies further into the next century. Becoming
                         part of Applied Materials also enables us to expand our
                         next-generation products, as well as broaden our
                         service and support capabilities."

                         The acquisition, which will be accounted for as a
                         pooling-of-interests, is expected to be closed by the
                         end of this calendar year or in early 1999, subject to,
                         among other things, regulatory approval and approval of
                         the stockholders of Consilium, Inc. Certain
                         stockholders of Consilium have already entered into
                         voting agreements in support of the merger.

     8.3    SEVERABILITY.  If any provision of this Voting Agreement 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 the remainder of such provision or the
validity or enforceability of any other provision of this Voting Agreement.
Each provision of this Voting Agreement is separable from every other provision
of 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
thereof and supersede all prior agreements and understandings between the
parties with respect thereto.  No addition to or modification of any provision
of this Voting Agreement shall be binding upon either party unless made in
writing and signed by both parties.

     8.5    ASSIGNMENT; BINDING EFFECT.  Except as provided herein, neither this
Voting Agreement nor any of the interests or obligations hereunder may be
assigned or delegated by Stockholder and any attempted or purported assignment
or delegation of any of such interests or obligations shall be void.  Subject to
the preceding sentence, this Voting Agreement shall be binding upon Stockholder
and his heirs, estate, executors, personal representatives, successors and
assigns, and shall inure to the benefit of Parent and its successors and
assigns.  Without limiting any of the restrictions set forth in Section 2 or
elsewhere in this Voting Agreement, this Voting Agreement shall be binding upon
any Person to whom any Subject Securities are transferred.  Nothing in this
Voting Agreement is intended to confer on any Person (other than Parent and its
successors and assigns) any rights or remedies of any nature.

                                       6

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

     8.8    GOVERNING LAW; VENUE.

               (A) This Voting Agreement and the Proxy shall be construed in
accordance with, and governed in all respects by, the laws of the State of
Delaware (without giving effect to principles of conflicts of laws).

               (B) Any legal action or other legal proceeding relating to this
Voting Agreement or the Proxy or the enforcement of any provision of this Voting
Agreement or the Proxy may be brought or otherwise commenced in any state or
federal court located in the County of Santa Clara, California. Stockholder: (i)
expressly and irrevocably consents and submits to the jurisdiction of each state
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 

                                       7
<PAGE>
 
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 the right of Parent to commence any legal
proceeding or otherwise proceed against Stockholder in any other forum or
jurisdiction.

          (C) STOCKHOLDER IRREVOCABLY WAIVES THE RIGHT TO A JURY TRIAL IN
CONNECTION WITH ANY LEGAL PROCEEDING RELATING TO THIS VOTING AGREEMENT OR THE
PROXY OR THE ENFORCEMENT OF ANY PROVISION OF THIS VOTING AGREEMENT OR THE PROXY.

     8.9    COUNTERPARTS.  This Voting Agreement may be executed by the parties
in separate counterparts, each of which when so executed and delivered shall be
an original, but all such counterparts shall together constitute one and the
same instrument.

     8.10   CAPTIONS.  The captions contained in this Voting Agreement are for
convenience of reference only, shall not be deemed to be a part of this Voting
Agreement and shall not be referred to in connection with the construction or
interpretation of this Voting Agreement.

     8.11   ATTORNEYS' FEES.  If any legal action or other legal proceeding
relating to this Voting Agreement or the enforcement of any provision of this
Voting Agreement is brought by one party against the other party, 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).

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

     8.13   CONSTRUCTION.

          (A) For purposes of this Voting Agreement, whenever the context
requires: the singular number shall include the plural, and vice versa; the
masculine gender shall include the feminine and neuter genders; the feminine
gender shall include the masculine and neuter genders; and the neuter gender
shall include masculine and feminine genders.

          (B) The parties agree that any rule of construction to the effect that
ambiguities are to be resolved against the drafting party shall not be applied
in the construction or interpretation of this Voting Agreement.

          (C) As used in this Voting Agreement, the words "include" and
"including," and variations thereof, shall not be deemed to be terms of
limitation, but rather shall be deemed to be followed by the words "without
limitation."

          (D) Except as otherwise indicated, all references in this Voting
Agreement to "Sections" and "Exhibits" are intended to refer to Sections of this
Voting Agreement and Exhibits to this Voting Agreement.

     IN WITNESS WHEREOF, Parent and Stockholder have caused this Voting
Agreement to be executed as of the date first written above.

                           FORM OF IRREVOCABLE PROXY


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

     This proxy is irrevocable, is coupled with an interest and is granted in
connection with the Voting Agreement, dated as of the date hereof, between
Parent and the undersigned (the "Voting Agreement"), and is granted in
consideration of Parent entering into the Agreement and Plan of Merger and
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
consents from stockholders of the Company, in favor of the approval and adoption
of the Reorganization Agreement and the approval of the Merger, and in favor of
each of the other actions contemplated by the Reorganization Agreement.

     The undersigned may vote the Shares on all other matters.

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

     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 

                                       10
<PAGE>
 
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 the remainder of such provision or the validity or
enforceability of any other provision of this proxy. Each provision of this
proxy is separable from every other provision of this proxy, and each part of
each provision of this proxy is separable from every other part of such
provision.

     This proxy shall terminate upon the earlier of the valid termination of the
Reorganization Agreement or the effective time of the Merger.
