shareholders of Company have on the date hereof entered into shareholder
agreements in the form attached hereto as Exhibit A (each a "Shareholder
                                          ---------          -----------

convertible into or exchangeable for shares of Company Common Stock, issued and
outstanding after the date hereof relative to such number as derived from
Section 2.2 hereof (except to the extent of stock options granted in accordance

Stock to be received by such holder) shall receive from Parent an amount of cash
(rounded to the nearest whole cent) equal to the product of (i) such fraction,

          1.7  Surrender of Certificates.
               -------------------------

                    (a)  Exchange Agent. Parent's transfer agent shall act as
                         --------------
exchange agent (the "Exchange Agent") in the Merger.
                     --------------

                    (b)  Parent to Provide Common Stock and Cash. Promptly after
                         ---------------------------------------
the Effective Time, Parent shall make available to the Exchange Agent for
exchange in accordance with this Article I, through such reasonable procedures
as Parent may adopt, (i) the shares of Parent Common Stock issuable pursuant to
Section 1.6(a) in exchange for shares of Company Common Stock outstanding
immediately prior to the Effective Time (provided that delivery of any shares
                                         --------
that are subject to vesting and/or repurchase rights in favor of Company shall
be in book entry form until such vesting and/or repurchase rights lapse) and
(ii) cash in an amount sufficient to permit payment of cash in lieu of
fractional shares pursuant to Section 1.6(f).

                    (c)  Exchange Procedures. As soon as reasonably practicable
                         -------------------
after the Effective Time, the Surviving Corporation shall cause to be mailed to
each holder of record of a certificate or certificates (the "Certificates")
                                                             ------------
which immediately prior to the Effective Time represented outstanding shares of
Company Common Stock, whose shares were converted into the right to receive
shares of Parent Common Stock (and cash in lieu of fractional shares) pursuant
to Section 1.6, (i) a letter of transmittal (which shall specify that delivery
shall be effected, and risk of loss and title to the Certificates shall pass,
only upon receipt of the Certificates by the Exchange Agent, and shall be in
such form and have such other provisions as Parent may reasonably specify) and
(ii) instructions for use in effecting the surrender of the Certificates in
exchange for certificates (or book entries in the case of shares that are
subject to vesting and/or repurchase rights in favor of Company) representing
shares of Parent Common Stock (and cash in lieu of fractional shares). Upon
surrender of a Certificate for cancellation to the Exchange Agent or to such
other agent or agents as may be appointed by Parent, together with such letter
of transmittal, duly completed and validly executed in accordance with the
instructions thereto, the holder of such Certificate shall be sent in exchange
therefor a certificate (or book entry in the case of shares that are subject to
vesting and/or repurchase rights) representing the number of whole shares of
Parent Common Stock and payment in lieu of fractional shares which such holder
has the right to receive pursuant to Section 1.6, and the Certificate so
surrendered shall forthwith be canceled. Until so surrendered, each outstanding
Certificate that, prior to the Effective Time, represented shares of Company
Common Stock will be deemed from and after the Effective Time to represent only
the right to receive upon surrender of such Certificate the merger consideration
contemplated by Section 1.6. Notwithstanding any other provision of this
Agreement, no interest will be paid or will accrue on any cash payable to
holders of Certificates pursuant to the provisions of this Article I.

                                       4


               (d)  Distributions With Respect to Unexchanged Shares. No
                    ------------------------------------------------
dividends or other distributions with respect to Parent Common Stock with a
record date after the Effective Time will be paid to the holder of any
unsurrendered Certificate with respect to the shares of Parent Common Stock
represented thereby until the holder of record of such Certificate shall
surrender such Certificate. Subject to applicable law, following surrender of
any such Certificate, there shall be paid to the record holder of the
certificates representing whole shares of Parent Common Stock issued in exchange
therefor, without interest, at the time of such surrender, the amount of any
such dividends or other distributions with a record date after the Effective
Time theretofore payable (but for the provisions of this Section 1.7(d)) with
respect to such shares of Parent Common Stock.

               (e)  Transfers of Ownership. If any certificate for shares of
                    ----------------------
Parent Common Stock is to be issued in a name other than that in which the
Certificate surrendered in exchange therefor is registered, it will be a
condition of the issuance thereof that the Certificate so surrendered will be
properly endorsed and otherwise in proper form for transfer and that the person
requesting such exchange will have paid to Parent or any agent designated by it
any transfer or other taxes required by reason of the issuance of a certificate
for shares of Parent Common Stock in any name other than that of the registered
holder of the Certificate surrendered, or established to the satisfaction of
Parent or any agent designated by it that such tax has been paid or is not
payable.

               (f)  No Liability. Notwithstanding anything to the contrary in
                    ------------
this Section 1.7, none of the Exchange Agent, the Surviving Corporation, Parent
or any party hereto shall be liable to any person for any amount properly paid
to a public official pursuant to any applicable abandoned property, escheat or
similar law.

          1.8  Termination of Exchange Agent Funding. Any portion of funds
               -------------------------------------
(including any interest earned thereon) or certificates for shares of Parent
Common Stock held by the Exchange Agent which have not been delivered to holders
of Certificates pursuant to this Article I within six months after the Effective
Time shall promptly be paid or delivered, as appropriate, to Parent, and
thereafter holders of Certificates who have not theretofore complied with the
exchange procedures set forth in and contemplated by Section 1.7 shall
thereafter look only to Parent (subject to abandoned property, escheat and
similar laws) for their claim for shares of Parent Common Stock and, only as
general creditors thereof, any cash in lieu of fractional shares of Parent
Common Stock and any dividends or distributions (with a record date after the
Effective Time) with respect to Parent Common Stock to which they are entitled.

          1.9  No Further Ownership Rights in Company Common Stock. All shares
               ---------------------------------------------------
of Parent Common Stock issued upon the surrender for exchange of shares of
Company Common Stock in accordance with the terms hereof (including any cash
paid in lieu of fractional shares) shall be deemed to have been issued in full
satisfaction of all rights pertaining to such shares of Company Common Stock,
and there shall be no further registration of transfers on the records of the
Surviving Corporation of shares of Company Common Stock which were outstanding
immediately prior to the Effective Time. If, after the Effective Time,
Certificates are presented to the Surviving Corporation for any reason, they
shall be canceled and exchanged as provided in this Article I.

                                       5


          1.10 Lost, Stolen or Destroyed Certificates. In the event any
               --------------------------------------
Certificates shall have been lost, stolen or destroyed, the Exchange Agent shall
issue in exchange for such lost, stolen or destroyed Certificates, upon the
making of an affidavit of that fact by the holder thereof, such shares of Parent
Common Stock (and cash in lieu of fractional shares) as may be required pursuant
to Section 1.6; provided, however, that Parent may, in its discretion and as a
                --------  -------
condition precedent to the issuance thereof, require the owner of such lost,
stolen or destroyed Certificates to deliver a bond in such sum as it may
reasonably direct as indemnity against any claim that may be made against
Parent, the Surviving Corporation or the Exchange Agent with respect to the
Certificates alleged to have been lost, stolen or destroyed.

          1.11 Tax and Accounting Consequences. It is intended by the parties
               -------------------------------
hereto that the Merger shall (a) constitute a reorganization within the meaning
of Section 368(a) of the Code and (b) qualify for accounting treatment as a
pooling of interests.

          1.12 Withholding Rights. Parent and the Surviving Corporation shall be
               ------------------
entitled to deduct and withhold from the number of shares of Parent Common Stock
otherwise deliverable under this Agreement, and from any other payments made
pursuant to this Agreement, such amounts as Parent and the Surviving Corporation
are required to deduct and withhold with respect to such delivery and payment
under the Code or any provision of federal, national, state, local, provincial
or foreign tax law. To the extent that amounts are so withheld, such withheld
amounts shall be treated for all purposes of this Agreement as having been
delivered and paid to the holder of shares of Company Common Stock in respect of
which such deduction and withholding was made by Parent and the Surviving
Corporation.

          1.13 Taking of Necessary Action; Further Action. If, at any time after
               ------------------------------------------
the Effective Time, any further action is necessary or desirable to carry out
the purposes of this Agreement and to vest the Surviving Corporation with full
right, title and possession to all assets, property, rights, privileges, powers
and franchises of Company and Merger Sub, the officers and directors of Company
and Merger Sub are fully authorized in the name of their respective corporations
or otherwise to take, and will take, all such lawful and necessary action, so
long as such action is not inconsistent with this Agreement.

          In this Agreement, any reference to a party's "knowledge" means such
                                                         ---------

Merger Sub as follows:

          2.1  Organization, Standing and Power. Each of Company and its
               --------------------------------
subsidiaries is a corporation duly organized and validly existing under the laws
of its jurisdiction of organization. Each of Company and its subsidiaries has
the corporate power to own its properties and to carry on its business as now
being conducted and as presently proposed to be conducted and is duly qualified
to do business and is in good standing in each jurisdiction in which the failure
to be so qualified and in good standing could reasonably be expected to have a
Material Adverse Effect on Company. Company has delivered to Parent a true and
correct copy of the Restated Articles of Incorporation (the "Articles of
                                                             -----------
Incorporation"), and Second Restated Bylaws or other charter documents, as

Neither Company nor any of its subsidiaries is in violation of any of the
provisions of its respective charter or bylaws or equivalent organizational
documents. Company is the owner of all outstanding shares of capital stock of
each of its subsidiaries and all such shares are duly authorized, validly
issued, fully paid and nonassessable. All of the outstanding shares of capital
stock of each such subsidiary are owned by Company free and clear of all liens,
charges, claims or encumbrances or rights of others. There are no outstanding
subscriptions, options, warrants, puts, calls, rights, exchangeable or
convertible securities or other commitments or agreements of any character
relating to the issued or unissued capital stock or other securities of any such
subsidiary, or otherwise obligating Company or any such subsidiary to issue,
transfer, sell, purchase, redeem or otherwise acquire any such securities.

exchangeable or exercisable for, any equity or similar interest in, any
corporation, partnership, limited liability company, joint venture or other
business association or entity (excluding securities in publicly traded
companies held for passive investment and comprising less than 1% of the
outstanding stock of such company).

          2.2  Capital Structure. The authorized capital stock of Company
               -----------------
consists of 15,000,000 shares of Common stock, $0.01 par value, of which there
were issued and outstanding as of the close of business on May 15, 2001,
7,889,987 shares, and 10,000,000 shares of Preferred Stock $0.01 par value of
which 150,000 shares have been designated as Series A Participating Preferred

ESPP"). All outstanding shares of Company Common Stock are duly authorized,
- ----
validly issued, fully paid and non-assessable and are free of any liens or
encumbrances, other than any liens or encumbrances created by or imposed upon
the holders thereof, and are not subject to preemptive rights or rights of first
refusal created by statute, the Articles of Incorporation or Bylaws of Company
or any agreement to which Company is a party or by which it is bound. Company

accepted enrollments in the Company ESPP. Except for (i) the rights created
pursuant to this Agreement, the Company Stock Option Plans and the Company ESPP
and (ii) Company's rights to repurchase any unvested shares under the Company
Stock Option Plans, there are no other options, warrants, calls, rights,

redeem, or cause to be issued, delivered, sold, repurchased or redeemed, any
shares of capital stock of Company or obligating Company to grant, extend,
accelerate the vesting of, change the price of, or otherwise amend or enter into
any such option, warrant, call, right, commitment or agreement. There are no
contracts, commitments or agreements relating to voting, purchase or sale of
Company's capital stock (other than those granting Company the right to purchase
unvested shares upon employment or service termination, and the Shareholder
Agreement) (i) between or among Company and any of its shareholders and (ii) to
the best of Company's knowledge, between or among any of Company's shareholders.
The terms of the Company Stock Option Plans permit the assumption of options to
purchase Parent Common Stock as provided in this Agreement, without the consent
or approval of the holders of such securities, shareholders, or otherwise. The
current "Offering Period" (as defined in the Company ESPP) commenced under the
         ---------------
Company ESPP on February 1, 2000 and will end on the date provided for in
Section 5.9(c), and except for

                                       8


the purchase rights granted on such commencement date to participants in the
current Offering Period, there are no other purchase rights or options
outstanding under the Company ESPP. The terms of the Company ESPP permit the
Company to shorten and terminate Offering Periods without the consent or

instruments in standard form) have been made available to Parent and such
agreements and instruments have not been amended, modified or supplemented since
being made available to Parent, and there are no agreements to amend, modify or
supplement such agreements or instruments in any case from the form made

qualified for exemptions pursuant to Rule 701 under the Securities Act for stock
issuances under compensatory benefit plans.

binding obligation of Company enforceable against Company in accordance with its
terms, except as enforceability may be limited by bankruptcy and other similar
laws affecting the rights and remedies of creditors generally and general
principles of equity. Except as set forth on Schedule 2.3, the execution and
                                             ------------
delivery of this Agreement by Company does not, and the consummation of the

               -----------------------------------

and, prior to the Effective Time, Company will have furnished to Parent true and
complete copies of any additional documents filed with the SEC by Company prior
to the Effective Time (collectively, the "Company SEC Documents"). Company has
                                          ---------------------
timely filed all forms, statements and documents required to be filed by it with
the SEC and The Nasdaq National Market since March 1, 2001. In addition, Company

Company SEC Documents filed prior to the Effective Time. All documents required
to be filed as exhibits to the Company SEC Documents have been so filed, and all
material contracts so filed as exhibits are in full force and effect, except
those which have expired in accordance with their terms. As of their respective
filing dates, the Company SEC Documents complied in all material respects with
the requirements of the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), and the Securities Act, and none of the Company SEC Documents
 ------------
contained any untrue statement of a material fact or omitted to state a material
fact required to be stated therein or necessary to make the statements made
therein, in light of the circumstances in which they were made, not misleading,
except to the extent corrected by a subsequently filed Company SEC Document. The
financial statements of Company, including the notes thereto, included in the
Company SEC Documents (the "Company Financial Statements") were complete and

SEC). The Company Financial Statements fairly present the consolidated financial
condition and operating results of Company and its subsidiaries at the dates and
during the periods indicated therein (subject, in the case of unaudited
statements, to normal, recurring year-end adjustments none of which
individually, or in the aggregate, are material). There has been no material
change in Company accounting policies since December 31, 2000.

          2.5  Absence of Certain Changes. Since March 31, 2001 (the "Company
               --------------------------                             -------
Balance Sheet Date"), Company has conducted its business in the ordinary course

Company or any of its subsidiaries is a party or by which it is bound and Parent
has been provided with true and complete copies of all such material amendments
and agreements; (vi) any amendment or change to the Articles of Incorporation or
Bylaws, except to the extent provided for in Section 1.4; or (vii) any increase

                                                       --------

period for application has not expired. Company has also furnished Parent with
the most recent Internal Revenue Service determination letter issued with

Employee Plan has been administered in accordance with its terms and in
compliance with the requirements prescribed by any and all statutes, rules and
regulations (including ERISA and the Code), except as would not have, in the
aggregate, a Material Adverse Effect on Company, and Company and each subsidiary

required to be performed by them under, are not in default in any material
respect under or violation of, and have no knowledge of any material default or

dates and a reasonable amount has been accrued for contributions to each Company

Employee Plan, no "reportable event" within the meaning of Section 4043 of ERISA
(excluding any such event for which the thirty (30) day notice requirement has
been waived under the regulations to Section 4043 of ERISA) nor any event
described in Section 4062, 4063 or 4041 or ERISA has occurred; (vii) no Company
Employee Plan is covered by, and neither Company nor any subsidiary or ERISA
Affiliate has incurred or expects to incur any liability under Title IV of ERISA

accordance with its terms, without liability to Parent (other than for benefits
accrued through the date of termination and ordinary administrative expenses

notices and reports to employees required to be filed, distributed or posted

so would not have a Material Adverse Effect. No suit, administrative proceeding,
action or other litigation has been brought, or to the knowledge of Company is
threatened, against or with respect to any such Company Employee Plan, including
any audit or inquiry by the IRS or United States Department of Labor. No payment
or benefit which will or may be made by Company to any employee will be

use its reasonable best efforts to take such action as may be required to cause
the expiration of the notice periods under the HSR or other Antitrust Laws with
respect to such transactions as promptly as possible after the execution of this
Agreement; provided, however, in no event shall either Parent or the Company
           --------  -------

subsidiaries shall, or shall be required to, divest any of their respective
businesses, product lines or assets, or to take or agree to take any other
action or agree to any limitation that would reasonably be expected to have a

hereto current as of such date. Each such option so assumed by Parent under this
Agreement shall continue to have, and be subject to, the same terms and
conditions set forth in the Company Stock Option Plans and the applicable stock
option agreements, immediately prior to the Effective Time, except that (i) such

options under the Company Stock Option Plans or accelerate the exercisability or
vesting of such options or the shares of Parent Common Stock which will be

qualify, to the maximum extent permissible, following the Effective Time as
incentive stock options as defined in Section 422 of the Code to the extent such
options qualified as incentive stock options prior to the Effective Time.

prior to the Effective Time to repurchase unvested shares of Company Common
Stock (the "Repurchase Options") shall continue in effect following the Merger
            ------------------
and shall thereafter continue to be exercisable by Parent upon the same terms
and conditions in effect immediately prior to the Effective Time, except that
the shares purchasable pursuant to the Repurchase Options and the purchase price
per share shall be adjusted to reflect the Exchange Ratio.

        (c) The Offering Period for the Company ESPP which commenced on February
1, 2000 shall terminate at close of business on the third business day preceding

the Company ESPP to terminate with such termination date, and thereafter no
Offering Periods shall commence and no purchase rights shall thereafter be
granted or exercised under the Company ESPP.  The Company employees who meet the
eligibility requirements for participation in the Parent Employee Stock Purchase
Plan shall be eligible to begin payroll deductions under that plan as of the
start date of the first offering period thereunder beginning after the Effective
Time.

Each such employee shall, with respect to any Parent plans or programs which
have co-payment, deductible or other co-insurance features, receive credit for
any amounts such individual has paid to date in the plan year of the Effective
Time under comparable plans or programs maintained by Company or any of its
subsidiaries prior to the Effective Time.  Each Continuing Employee and eligible

excluded from Parent's employee group health plan or limited in coverage
thereunder by reason of any waiting period restriction or pre-existing condition
limitation.

        (e) Unless Parent consents otherwise in writing, Company shall take all
action necessary to terminate, or cause to terminate, before the Effective Time,
any Company Benefit Plan that is a 401(k) plan or other defined contribution
retirement plan or employee stock purchase plan.

unless otherwise unanimously agreed by the Board of Directors of Surviving
Corporation; provided that nothing shall require the use of such brands if such
             --------
use would expose the Parent or Surviving Corporation to any exposure to a third
party for claims of infringement of tradename, trademarks or other infringement
of any Third Party Intellectual Property as a consequence of such continued use.

require Surviving Corporation to maintain the business confidentiality of its
customers and suppliers separate, and where appropriate confidential from,
Parent.

Final Date may, at the request of either party, be extended to December 31, 2001

November 16, 2001 is the failure of the conditions set forth in Section 6.1(b)
and/or Section 6.1(d) (although such extension shall not occur if the failure of
such conditions has principally been caused or resulted from the action or
failure to act constituting a breach, in any material respect, of this

extension does not consent to such extension); and; provided further that the

right to terminate this Agreement under this Section 7.1(b) shall not be

been cured within ten (10) business days of receipt by Company of written notice
of such breach;

          (d) by Parent, if the condition in Section 6.3(b) shall not have been
satisfied and such condition shall not have been cured within ten (10) business
days of receipt by Company of written notice of such Material Adverse Effect;

          (e) by Company, if Parent shall breach any of its representations,
warranties or obligations hereunder to an extent that would cause the condition
set forth in Section 6.2(a) not to be satisfied and such breach shall not have
been cured within ten (10) business days following receipt by Parent of written
notice of such breach;

have been satisfied and such condition shall not have been cured within ten (10)
business days following receipt by Parent of written notice of such Material
Adverse Effect;

          (g) by Parent, if: (i) a Trigger Event (as defined in Section 7.3(e))

conditions) that the Company's shareholders vote to approve the Merger and this
Agreement (a "Recommendation"), or shall have withdrawn  or modified its

Recommendation in a manner adverse to Parent (including by failing to include
such Recommendation in the Proxy Statement or by imposing conditions upon such
Recommendation), or shall have resolved to do any of the foregoing, or shall
have failed to reaffirm its Recommendation within ten business days of a written
request to do so by Parent; (iii) the Board of Directors of Company shall have
recommended, endorsed, approved, accepted, or agreed to a Takeover Proposal or
shall have entered into any letter of intent or similar document or agreement
relating to any Takeover Proposal, or shall have resolved to do any of the
foregoing; or (iv) any Company Representative shall have failed to comply in any
material respect with Section 4.3; or (v) the Company shall have breached its
obligations under Section 5.2.

          (h) by either Parent or Company, if: (i) any permanent injunction or
other order of a court or other competent authority preventing the consummation
of the Merger shall have become final and nonappealable, or (ii) any required
approval of the shareholders of Company shall not have been obtained by reason

to terminate this Agreement under this subsection (ii) shall not be available to

                             SHAREHOLDER AGREEMENT

          THIS SHAREHOLDER AGREEMENT (this "Agreement") is entered into as of
                                            ---------
May 16, 2001, by and among Credence Systems Corporation, a Delaware corporation
("Parent"), Iguana Acquisition Corporation, an Oregon corporation and wholly
  ------
owned subsidiary of Parent ("Merger Sub"), and the undersigned shareholder
                             ----------
("Shareholder") of Integrated Measurement Systems, Inc., a Oregon corporation
- -------------
("Company").
- ---------

                                   RECITALS:

          WHEREAS, Parent has agreed to acquire the outstanding securities of
Company pursuant to a statutory merger of Merger Sub with and into Company (the
"Merger") effected in part through the conversion of each outstanding share of
 ------
capital stock of Company (the "Company Capital Stock"), into shares of common
                               ---------------------
stock of Parent (the "Parent Shares") at the rate set forth in the Agreement and
                      -------------
Plan of Merger and Reorganization dated as of May 16, 2001 by and among Parent,
Merger Sub and Company (such agreement as it may be amended or restated is
hereinafter referred to as the "Reorganization Agreement") (the "Transaction");
                                ------------------------         -----------

          WHEREAS, Shareholder is the registered and beneficial owner of such
number of shares of the outstanding Company Capital Stock as is indicated on the
signature page of this Agreement (the "Shares"); and
                                       ------

          WHEREAS, in order to induce Parent to enter into the Transaction,
certain shareholders of Company have agreed not to transfer or otherwise dispose
of any of the Shares, or any other shares of Company Capital Stock acquired by
such shareholder hereafter and prior to the Expiration Date (as defined in
Section 1.1 below), and have agreed to vote the Shares and any other such shares
of Company Capital Stock so as to facilitate consummation of the Transaction.

          NOW, THEREFORE, in consideration of the promises and mutual
agreements, provisions and covenants set forth in the Reorganization Agreement,
the parties hereto agree as follows:

          1.   Share Ownership and Agreement to Retain Shares.
               ----------------------------------------------

               1.1  Transfer and Encumbrance.
                    ------------------------

                    (a)  Shareholder represents, warrants and, in subclause (v)
below, covenants to Parent that (i) Shareholder is the beneficial owner of that
number of Shares of Company Capital Stock set forth on the signature page
hereto; (ii) except as otherwise set forth on the signature page hereto,
Shareholder has held such Company Capital Stock at all times since the date set
forth on such signature page; (iii) the Shares constitute the Shareholder's
entire equity interest in the outstanding Company Capital Stock; (iv) no other
person or entity not a signatory to this Agreement has a beneficial interest in
or a right to acquire the Shares or any


portion of the Shares; and (v) the Shares are and will be at all times up until
the Expiration Date free and clear of any liens, claims, rights of first
refusal, options, charges or other encumbrances. For the avoidance of doubt,
nothing in this Agreement shall deem shares of outstanding Company Capital Stock
or options to acquire Company Capital Stock held by an officer, director or
employee of Shareholder to be beneficially owned by Shareholder.

               (b)  Shareholder agrees not to transfer (except as may be
specifically required by court order or applicable law), sell, exchange, pledge
or otherwise dispose of or encumber the Shares or any New Shares (as defined in
Section 1.2 below), or to make any offer or agreement relating thereto, at any
time prior to the Expiration Date. As used herein, the term "Expiration Date"
                                                             ---------------
shall mean the earlier to occur of (A) the Effective Time (as defined in the
Reorganization Agreement) of the Transaction, and (B) the termination of the
Reorganization Agreement pursuant to its terms.

          1.2  New Shares.  Shareholder agrees that any shares of Company
               ----------
Capital Stock that Shareholder purchases or with respect to which Shareholder
otherwise acquires beneficial ownership after the date of this Agreement and
prior to the Expiration Date ("New Shares") shall be subject to the terms and
                               ----------
conditions of this Agreement to the same extent as if they constituted Shares.

     2.   Agreement to Vote Shares. Prior to the Expiration Date, at every
          ------------------------
meeting of the shareholders of Company called with respect to any of the
following, and at every adjournment thereof, and on every action or approval by
written resolution of the shareholders of Company with respect to any of the
following, Shareholder shall vote the Shares and any New Shares in favor of
approval of the Transaction and any matter or actions required to facilitate the
Transaction.

     3.   Irrevocable Proxy. Shareholder is hereby delivering to Parent a duly
          -----------------
executed proxy in the form attached hereto as Exhibit A (the "Proxy") with
                                              ---------  ----------
respect to each meeting of shareholders of Company, such Proxy to cover the
total number of Shares and New Shares in respect of which Shareholder is
entitled to vote at any such meeting. Upon the execution of this Agreement by
the Shareholder, the Shareholder hereby revokes any and all prior proxies given
by the Shareholder with respect to the Shares and agrees not to grant any
subsequent proxies with respect to the Shares or any New Shares until after the
Expiration Date.

     4.   Representations, Warranties and Covenants of Shareholder. Shareholder
          --------------------------------------------------------
hereby represents, warrants and/or covenants to Parent as follows:

               (a)  Until the Expiration Date, the Shareholder will not (and
will use such Shareholder's commercially reasonable efforts to cause the
Company, its affiliates, officers, directors and employees and any investment
banker, attorney, accountant or other agent retained by such Shareholder, not
to): (i) initiate or solicit, directly or indirectly, any proposal, plan of
offer to acquire all or any substantial part of the business or properties or
Company Capital Stock, whether by merger, purchase of assets, tender offer or
otherwise, or to liquidate Company or otherwise distribute to the Shareholders
of Company all or any substantial part of the business, properties or Company
Capital Stock (each, an "Acquisition Proposal"); (ii) initiate, directly or
                         --------------------
indirectly, any contact with any person in an effort to or with a view towards

                                       2


soliciting any Acquisition Proposal; (iii) furnish information concerning
Company's business, properties or assets to any corporation, partnership,
limited liability company, limited partnership, person or other entity or group
(other than Parent or Merger Sub, or any associate, agent or representative of
Parent or Merger Sub), under any circumstances that would reasonably be expected
to relate to an actual or potential Acquisition Proposal; or (iv) negotiate or
enter into discussions or an agreement, directly or indirectly, with any entity
or group with respect of any potential Acquisition Proposal provided that, in
the case of clauses (iii) and (iv), the foregoing shall not prevent Shareholder,
in Shareholder's capacity as a director or officer (as the case may be) of
Company, from taking any actions permitted under Section 4.3 of the
Reorganization Agreement. In the event the Shareholder shall receive or become
aware of any Acquisition Proposal subsequent to the date hereof, such
Shareholder shall promptly inform Parent as to any such matter and the details
thereof to the extent possible without breaching any other agreement to which
such Shareholder is a party or violating its fiduciary duties.

               (b)  Shareholder is competent to execute and deliver this
Agreement, to perform its obligations hereunder and to consummate the
transactions contemplated hereby. This Agreement has been duly and validly
executed and delivered by Shareholder and, assuming the due authorization,
execution and delivery by Parent and Merger Sub, constitutes a legal, valid and
binding obligation of Shareholder, enforceable against Shareholder in accordance
with its terms except that (i) the enforceability thereof may be subject to
applicable bankruptcy, insolvency or other similar laws, now or hereinafter in
effect affecting creditors' rights generally and (ii) the availability of the
remedy of specific performance or injunctive or other forms of equitable relief
may be subject to equitable defenses and would be subject to the discretion of
the court before which any proceeding therefor may be brought.

               (c)  The execution and delivery of this Agreement by Shareholder
does not, and the performance of this Agreement by Shareholder shall not, result
in any breach of or constitute a default (or an event that with notice or lapse
of time or both would become a default) under, or give to others any rights of
termination, amendment, acceleration or cancellation of, or result in the
creation of a lien or encumbrance, on any of the Shares or New Shares pursuant
to, any note, bond, mortgage, indenture, contract, agreement, commitment, lease,
license, permit, franchise or other instrument or obligation to which
Shareholder is a party or by which Shareholder or the Shares or New Shares are
or will be bound or affected.

          5.   Additional Documents.  Shareholder hereby covenants and agrees to
               --------------------
execute and deliver any additional documents necessary, in the reasonable
opinion of Parent, to carry out the purpose and intent of this Agreement.

          6.   [Reserved].
               ----------

          7.   Termination.  This Agreement and the Proxy delivered in
               -----------
connection herewith shall terminate and shall have no further force or effect as
of the Expiration Date.

          8.   Confidentiality.  Shareholder agrees (i) to hold any information
               ---------------
regarding this Agreement and the Transaction in strict confidence, and (ii) not
to divulge any such information to any third person not subject to
confidentiality obligations, until such time as the Transaction has been
publicly disclosed by Parent, except as may otherwise be required by law.

                                       3


          9.   Miscellaneous.
               -------------

               9.1  Severability. If any term, provision, covenant or
                    ------------
restriction of this Agreement or the Proxy is held by a court of competent
jurisdiction to be invalid, void or unenforceable, then the remainder of the
terms, provisions, covenants and restrictions of this Agreement shall remain in
full force and effect and shall in no way be affected, impaired or invalidated.

               9.2  Binding Effect and Assignment. This Agreement and all of the
                    -----------------------------
provisions hereof shall be binding upon and inure to the benefit of the parties
hereto and their respective successors and permitted assigns, but, except as
otherwise specifically provided herein, neither this Agreement nor any of the
rights, interests or obligations of the parties hereto may be assigned by either
of the parties hereto without the prior written consent of the other. This
Agreement is binding upon Shareholder in Shareholder's capacity as a shareholder
of Company (and not in Shareholder's capacity as a director or officer, as the
case may be, of Company) and only with respect to the specific matters set forth
herein.

               9.3  Amendment and Modification. This Agreement may not be
                    --------------------------

of a written agreement executed by the parties hereto.

               9.4  Specific Performance; Injunctive Relief. The parties hereto
                    ---------------------------------------
acknowledge that Parent will be irreparably harmed and that there will be no
adequate remedy at law for a violation of any of the covenants or agreements of
Shareholder set forth herein. Therefore, it is agreed that, in addition to any
other remedies that may be available to Parent or Merger Sub upon any such
violation, Parent and Merger Sub shall have the right to seek to enforce such
covenants and agreements by specific performance, injunctive relief or by any
other means available to Parent or Merger Sub at law or in equity, in connection
with such enforcement and waives any requirement for the security or posting of
any bond in connection with such enforcement.

Oregon Business Corporation Act.  The separate existence of Iguana Acquisition
Corporation, which is sometimes hereinafter referred to as the "non-surviving
corporation," shall cease at the Effective Time in accordance with the
provisions of the Oregon Business Corporation Act.

     2. The Articles of Incorporation of the surviving corporation at the
Effective Time shall be the Articles of Incorporation of said surviving
corporation as amended to read as follows:

"

                                      I.

               The name of the corporation is Integrated Measurement Systems,
               Inc.

                                      II.

               The aggregate number of shares which the corporation shall have
               authority to issue is 1,000 shares of common stock.  The shares
               of common stock have unlimited voting rights and are entitled to
               receive the net assets of the corporation.  The par value of the
               common stock is $0.001 per share.

                                     III.

               the corporation for notices is c/o CT Corporation System, 601
               S.W. Second Avenue, Suite 2050, Portland, Oregon 97204.


                                      IV.

               The corporation is authorized to purchase shares of common stock
               from present and former employees, consultants and directors
               pursuant to the arrangements approved by the Board of Directors
               when applying the provisions of the Oregon Business Corporation
               Act to determine the lawfulness of any such purchase.

                                      V.

               No director of the corporation shall be personally liable to the
               corporation or its shareholders for monetary damages for conduct
               as a director; provided that this Article shall not eliminate the
               liability of a director for any act or omission for which such
               elimination of liability is not permitted under the Oregon
               Business Corporation Act.  No amendment to the Oregon Business
               Corporation Act that further limits the acts or omissions for
               which elimination of liability is permitted shall affect the
               liability of a director for any act or omission that occurs prior
               to the effective date of such amendment.

                                      VI.

               A.  Indemnification. The corporation shall indemnify to the
                   ---------------
                   fullest extent not prohibited by law any Person who was or is
                   a party or is threatened to be made a party to any Proceeding
                   against all expenses (including attorneys' fees), judgments,
                   fines, and amounts paid in settlement actually and reasonably
                   incurred by the Person in connection with such Proceeding.
                   Notwithstanding the foregoing, the corporation shall not
                   indemnify any Person from or on account of acts or omissions
                   of such Person of a type for which liability could not be
                   eliminated for a director under ORS 60.047(2)(d).

               B.  Advancement of Expenses. Expenses incurred by a Person in
                   -----------------------
                   defending a Proceeding shall in all cases be paid by the
                   corporation in advance of the final disposition of such
                   Proceeding at the written request of such Person, if the
                   Person:

                   1.  furnishes the corporation a written affirmation of the
                       Person's good faith belief that such Person has met the
                       standard of conduct described in the Oregon Business
                       Corporation Act or is entitled to be indemnified by the
                       corporation under any other indemnification rights
                       granted by the corporation to such Person; and

                   2.  furnishes the corporation a written undertaking to repay
                       such advance to the extent it is ultimately determined by
                       a court that such Person is not entitled to be
                       indemnified by the corporation under this Article or
                       under any other indemnification rights granted by the
                       corporation to such Person.

                                       2


                       Such advances shall be made without regard to the
                       Person's ability to repay such advances and without
                       regard to the Person's ultimate entitlement to
                       indemnification under this Article or otherwise.

               C.   Definition of "Proceeding" and "Person". The term
                    --------------------------------------
                    "Proceeding" means any threatened, pending, or completed

                    criminal, administrative, or investigative nature, in which
                    an individual may be or may have been involved as a party or
                    otherwise by reason of the fact that the individual is or
                    was a director or officer of the corporation or a fiduciary
                    within the meaning of the Employee Retirement Income

                    Article. The term "Person" means any individual serving in a
                    capacity described in this Paragraph.

                    ----------------------------------------
                    shall not be deemed exclusive of any other rights to which
                    those indemnified may be entitled under any statute,
                    agreement, general or specific action of the board of
                    directors, vote of shareholders or otherwise, both as to
                    action in the official capacity of the Person indemnified
                    and as to action in another capacity while holding office,
                    (ii) shall continue as to a Person who has ceased to be a
                    director or officer, (iii) shall inure to the benefit of the
                    heirs, executors, and administrators of such Person, and

                    ----------
                    prospective and no repeal or modification hereof shall
                    adversely affect the rights under this Article in effect at
                    the time of the alleged occurrence of any action or omission
                    to act that is the cause of any Proceeding."

amended and changed in the manner prescribed by the provisions of the Oregon

                         -----------------------------



May 16, 2001


Credence Systems Corporation
215 Fourier Avenue
Fremont, California 94539

Ladies and Gentlemen:

     The undersigned is a holder of shares of common stock (the "Company Common
Stock") of Integrated Measurement Systems, Inc., an Oregon corporation (the
"Company").  Pursuant to the terms of that certain Agreement and Plan of Merger
and Reorganization, dated as of May 16, 2001, among the Company, Credence
Systems Corporation, a Delaware corporation (the "Parent"), and Iguana
Acquisition Corporation, an Oregon corporation and a wholly owned subsidiary of
Parent ("Merger Sub"), Merger Sub will be merged with and into the Company and
the Company will become a wholly owned subsidiary of Parent (the "Merger").  In
connection with the Merger, the undersigned, as a holder of Company Common
Stock, will be entitled to receive shares of common stock of Parent (the
"Securities") in exchange for the shares of Company Common Stock held by the
undersigned at the effective time of the Merger.

     The undersigned acknowledges that the undersigned may be deemed an
"affiliate" of Company within the meaning of Rule 145 ("Rule 145") promulgated
under the Securities Act of 1933, as amended (the "Act"), and/or as such term is
used in and for purposes of Accounting Series Release Nos. 130 and 135, as
amended, of the Securities and Exchange Commission (the "Commission"), although
nothing contained herein shall be construed as an admission of such status.

     If in fact the undersigned were an affiliate of the Company under the Act,
the undersigned's ability to sell, assign or transfer any Securities received by
the undersigned in exchange for any shares of Company Common Stock pursuant to
the Merger may be restricted unless such sale, assignment or transfer is
registered under the Act or an exemption from such registration is available.
The undersigned understands that such exemptions are limited and the undersigned
has obtained advice of counsel as to the nature and conditions of such
exemptions, including information with respect to the applicability to the sale
of such Securities of Rules 144 and 145(d) promulgated under the Act.

     The undersigned hereby represents to and covenants with Parent that it will
not sell, assign or transfer any Securities received by the undersigned in
exchange for shares of Company Common Stock pursuant to the Merger except (i)
pursuant to an effective registration statement under the Act, (ii) by a sale
made in conformity with the volume and other limitations of Rule 145 (and
otherwise in accordance with Rule 144 under the Act, if the undersigned is an
affiliate of Parent and if so required at the time) or (iii) in a transaction
which, in the opinion of


independent counsel reasonably satisfactory to the Company or as described in a
"no-action" or interpretive letter from the staff of the Commission reasonably
satisfactory to Parent, is not required to be registered under the Act.

     The undersigned understands that Parent is under no obligation to register
the sale, assignment, transfer or other disposition of the Securities by the
undersigned or on behalf of the undersigned under the Act or to take any other
action necessary in order to make compliance with an exemption from such
registration available solely as a result of the Merger.

     In the event of a sale of Securities pursuant to Rule 145, upon the request
of Parent, the undersigned will supply Parent with evidence of compliance with
such Rule, in the form of customary seller's and broker's Rule 145
representation letters or as Parent may otherwise reasonably request.  The
undersigned understands that Parent may instruct its transfer agent to withhold
the transfer of any Securities disposed of by the undersigned in a manner
inconsistent with this letter.

     The undersigned acknowledges and agrees that appropriate legends will be
placed on certificates representing Securities received by the undersigned in
the Merger or held by a transferee thereof, which legends will be removed (i) by
delivery of substitute certificates upon receipt of a letter from the Staff of
the Commission, or an opinion of counsel in form and substance reasonably
satisfactory to Parent, to the effect that such legends are no longer required
for the purposes of the Act and the rules and regulations of the Commission
promulgated thereunder, (ii) in the event of a sale of the Securities which has
been registered under the Act or made in conformity with the provisions of Rule
145.

     Parent covenants that, for so long as and to the extent necessary to permit
the undersigned to sell the shares of Parent Common Stock pursuant to Rule 145
and, to the extent applicable, Rule 144, Parent shall use all commercially
reasonable efforts to (i) file, on a timely basis, all reports and data required
to be filed with the Commission by it pursuant to Section 13 of the Securities
Exchange Act of 1934, as amended (the "1934 Act") and (ii) furnish to the
undersigned upon request a written statement as to whether Parent has complied
with such reporting requirements during the twelve (12) months preceding any
proposed sale of the shares of Parent Common Stock by the undersigned under Rule
145.

     Parent represents that it has filed all reports required with the
Commission under Section 13 of the 1934 Act during the preceding twelve (12)
months.

     The undersigned further represents to and convenants with Parent that, in
the event that the Merger may be accounted for as a pooling of interests,  (i)
the undersigned has not and will not, during the 30 days prior to the effective
time of the Merger sell, transfer or otherwise dispose of, or reduce any risk
relative to, any securities of the Company or Parent and (ii) the undersigned
will not, after the effective time of the Merger, sell, transfer or otherwise
dispose of, or reduce any risk relative to, the Securities, whether received by
the undersigned in the Merger or otherwise, until after such time as financial
results covering at least 30 days of post-Merger operations of Parent (including
the combined operations of the Company and Parent) have been published by Parent
in the form of a quarterly earnings report, an effective registration statement
filed with the Commission, a report to the Commission on Form 10-K, 10-Q or 8-K,
or any other public filing or announcement which includes such results of
operations, except in the cases of


clauses (i) and (ii) of this paragraph to the extent permitted by, and in
accordance with, SEC Accounting Series Release 135 and SEC Staff Accounting
Bulletins 65 and 76 if and to the extent that such release and bulletins remain
in full force and effect at the relevant time. Notwithstanding the foregoing, in
the event that the Merger may not be eligible to be accounted for as a pooling
of interests, the covenants of the undersigned in this paragraph shall cease and
terminate.

     The undersigned further understand and agree that this letter agreement
shall apply to all shares of Company Common Stock and Securities that it is
deemed to beneficially own pursuant to applicable federal securities law.

     The undersigned acknowledges that it has carefully reviewed this letter and
understands the requirements hereof and the limitations imposed upon the
distribution, sale, transfer or other disposition of Securities.

Sincerely,


[AFFILIATE]
