ITEM 1.  DESCRIPTION OF SECURITIES TO BE REGISTERED

     Pursuant to a Rights Agreement dated March 25, 1998 (the "Rights 
Agreement") between Integrated Measurement Systems, Inc. (the "Company") and 
ChaseMellon Shareholder Services, L.L.C., as Rights Agent (the "Rights 
Agent"), the Company's Board of Directors has declared a dividend of one 
right ("Right") to purchase one one-hundredth of a share of the Company's 
Series A Participating Preferred Stock ("Series A Participating Preferred 
Stock") for each outstanding share of Common Stock, $.01 par value ("Common 
Stock"), of the Company. The dividend is payable to shareholders of record as 
of the close of business on April 17, 1998 (the "Record Date"). Each Right 
entitles the registered holder to purchase from the Company one one-hundredth 
of a share of Series A Participating Preferred Stock at an exercise price of 
$70.00, subject to adjustment (the "Purchase Price").

     In connection with its adoption of the Shareholder Rights Plan, the 
Board of Directors has amended the Company's Restated Bylaws to opt out of 
Oregon's Control Share Statute.  The Statute provides that an acquiring 
person is prohibited from voting shares of an Oregon corporation acquired in 
a control share acquisition unless and until the shareholders, at a special 
meeting demanded by the acquiring person, vote to restore voting rights by a 
majority of the outstanding shares, excluding the control shares and certain 
other shares.  A control share acquisition is one that causes the total 
voting power of the acquiring person to exceed one-fifth, one-third or 
one-half of the total voting power of all the voting shares without the prior 
approval of the issuing company's board of directors.  The Board opted out of 
the Statute because it determined that the Shareholder Rights Plan offers 
greater protection to the Company's shareholders against substantial share 
acquisitions that are not approved by the Board in advance.

     The following summary of the principal terms of the Rights Agreement is 
a general description only and is subject to the detailed terms and 
conditions of the Rights Agreement. A copy of the Rights Agreement is 
attached as Exhibit 4.1 to this Registration Statement and is incorporated 
herein by reference.

RIGHTS EVIDENCED BY COMMON STOCK CERTIFICATES

     The Rights will not be exercisable until the Distribution Date (defined 
below). Certificates for the Rights ("Rights Certificates") will not be sent 
to shareholders and the Rights will attach to and trade only together with 
the Common Stock. Accordingly, Common Stock certificates outstanding on the 
Record Date will evidence the Rights related thereto, and Common Stock 
certificates issued after the Record Date will contain a notation 
incorporating the Rights Agreement by reference. Until the Distribution Date 
(or earlier redemption or expiration of the Rights), the surrender or 
transfer of any certificates for Common Stock, outstanding as of the Record 
Date, even without notation or a copy of the Summary of Rights being attached 
thereto, will also constitute the surrender or transfer of the Rights 
associated with the Common Stock represented by such certificate.

DISTRIBUTION DATE

     The Rights will separate from the Common Stock, Rights Certificates will 
be issued and the Rights will become exercisable upon the earlier of: (i) the 
first date of public announcement (the "Stock Acquisition Date") that a 
person or group of affiliated or associated persons has acquired, or obtained 
the right to acquire, beneficial ownership of 20% or more of the outstanding 
Common Stock in a transaction not approved by the Board of Directors (an 
"Acquiring Person"), or (ii) ten business days (or such later date as the 
Board may determine) following the commencement of, or announcement of an 
intention to make, a tender offer or exchange offer the consummation of which 
would result in the beneficial ownership by a person or group of 20% or more 
of the outstanding Common Stock in a transaction not approved by the Board of 
Directors.  The earlier of such dates is referred to as the "Distribution 
Date."



PROVISIONS RELATING TO CADENCE DESIGN SYSTEMS, INC.

     The Rights Plan includes grandfathering provisions that exempt Cadence 
Design Systems, Inc. ("Cadence") at its current level of Common Stock 
ownership (presently approximately 37%) and further permit Cadence and its 
subsidiaries to acquire up to an additional 7.5% of the then outstanding IMS 
shares without triggering the Rights.  Thus, based on its current level of 
ownership, Cadence may acquire up to an approximate 44.5% ownership interest 
in Company Common Stock without triggering the Rights.  However, dispositions 
of its existing shares will reduce Cadence's maximum permissible level of 
ownership share-for-share.  In addition, the grandfathering provisions 
terminate upon Cadence's ownership first falling below 20% of the Company's 
Common Stock.

ISSUANCE OF RIGHTS CERTIFICATES; EXPIRATION OF RIGHTS

     As soon as practicable following the Distribution Date, separate Rights 
Certificates will be mailed to holders of record of the Common Stock as of 
the close of business on the Distribution Date and such separate Rights 
Certificates alone will evidence the Rights from and after the Distribution 
Date.  All Common Stock issued prior to the Distribution Date will be issued 
with Rights.  The Rights will expire on the earlier of (i) March 25, 2008 
(the "Final Expiration Date") and (ii) redemption or exchange of the Rights 
as described below.

INITIAL EXERCISE OF THE RIGHTS

     Following the Distribution Date, and until one of the further events 
described below, each Right will entitle its holder to receive, upon exercise 
and the payment of the Purchase Price, one one-hundredth of a share of the 
Series A Participating Preferred Stock. In the event that the Company does 
not have sufficient Series A Participating Preferred Stock available for all 
Rights to be exercised, or the Board decides that such action is necessary 
and not contrary to the interest of the Rights holders, the Company may 
instead substitute cash, assets or other securities for the Series A 
Participating Preferred Stock for which the Rights would have been 
exercisable under this provision or as described below.

RIGHT TO BUY COMPANY COMMON STOCK

     Unless the Rights are earlier redeemed, in the event that there shall be 
an Acquiring Person, then proper provision will be made so that each holder 
of a Right which has not theretofore been exercised (other than Rights 
beneficially owned by the Acquiring Person or any transferee thereof, which 
will thereafter be void) will thereafter have the right to receive, upon 
exercise and payment of the Purchase Price, Common Stock (or, in certain 
circumstances as determined by the Board of Directors, cash, other property 
or other securities) having a value equal to two times the Purchase Price.  
Such provision is also required to be made in the event that, during such 
time as there shall be an Acquiring Persons, such Acquiring Person's 
beneficial ownership is increased by more than 1% as a result of certain 
reclassifications, recapitalizations or other transactions involving the 
Company or its subsidiaries.  Rights are not exercisable following the 
occurrence of an event described above until such time as the Rights are no 
longer redeemable by the Company as set forth below.

RIGHT TO BUY ACQUIRING COMPANY STOCK

     Similarly, unless the Rights are earlier redeemed, in the event that, 
after the Stock Acquisition Date, (i) the Company is acquired in a merger or 
other business combination transaction, or (ii) 50% or more of the Company's 
assets or earning power are sold (other than in transactions in the ordinary 
course of business), proper provision will be made so that each holder of a 
Right which has not theretofore been exercised (other than Rights 
beneficially owned by the Acquiring Person, which will thereafter be void) 



will thereafter have the right to receive, upon exercise and payment of the 
Purchase Price, shares of common stock of the acquiring company (or, in 
certain circumstances, its parent) having a value equal to two times the 
Purchase Price.

BOARD APPROVAL

     The Rights will not become exercisable if any acquisition of 20% or more 
of the Company's outstanding Common Stock has been pre-approved by a majority 
of the Board of Directors of the Company.  The Rights will also not become 
exercisable pursuant to an offer for all outstanding shares of Common Stock 
at a price and upon terms that a majority of the Board of Directors 
determines to be in the best interest of the Company and its shareholders.

EXCHANGE PROVISION

     At any time after any Person becomes an Acquiring Person but prior to 
any Person becoming the beneficial owner of 50% or more of the Common Stock 
then outstanding, the Board of Directors of the Company may exchange the 
Rights (other than Rights owned by the Acquiring Person), in whole or in 
part, for one share of Common Stock per Right.

REDEMPTION

     At any time on or prior to the close of business on the earlier of (i) 
the close of business on the Stock Acquisition Date, or (ii) the close of 
business on the Final Expiration Date, the Company may redeem the Rights in 
whole, but not in part, at a price of $0.001 per Right.

ADJUSTMENTS TO PREVENT DILUTION

     The Purchase Price payable, the number of Rights, and the number of 
shares of Series A Participating Preferred Stock or Common Stock or other 
securities issuable upon exercise of the Rights are subject to adjustment 
from time to time in connection with dilutive issuances by the Company as set 
forth in the Rights Agreement.

CASH PAID INSTEAD OF ISSUING FRACTIONAL SHARES

     No fractional portion of a share of Common Stock will be issued upon 
exercise of a Right, and in lieu thereof, an adjustment in cash will be made 
based on the market price of the Common Stock on the last trading date prior 
to the date of exercise.

NO SHAREHOLDERS' RIGHTS PRIOR TO EXERCISE

     Until a Right is exercised, the holder thereof, as such, will have no 
rights as a shareholder of the Company  (other than any rights resulting from 
such holder's ownership of Common Stock), including, without limitation, the 
right to vote or to receive dividends.

AMENDMENT OF RIGHTS AGREEMENT

     Other than those provisions relating to the rights, duties and 
obligations of the Rights Agent and certain principal economic terms of the 
Rights, any of the provisions of the Rights Agreement may be supplemented or 
amended by the Board of Directors in any manner prior to the close of 
business on the Distribution Date. After the Distribution Date, the 
provisions of the Rights Agreement may be amended by the Board in order to 
cure any ambiguity, defect or inconsistency, to make changes which do not 
adversely affect the interests of holders of Rights (excluding the interests 
of any Acquiring Person), or to shorten or lengthen any time period under the 
Rights Agreement; provided, however, that no amendment to adjust the time 
period governing redemptions shall be made at such time as the Rights are not 
redeemable.



RIGHTS AND PREFERENCES OF THE SERIES A PARTICIPATING PREFERRED STOCK

     Series A Participating Preferred Stock purchasable upon exercise of the 
Rights will not be redeemable. Each share of Series A Participating Preferred 
Stock will be entitled to an aggregate quarterly dividend of the greater of 
$70 and 100 times the aggregate per share amount for all non-cash dividends 
declared on the Common Stock.  In the event of liquidation, the holders of 
the Series A Participating Preferred Stock will receive all accrued but 
unpaid dividends plus an amount per share equal to 100 times the per share 
amount to be distributed to the holders of the Common Stock after certain 
adjustments. Each share of Series A Participating Preferred Stock will have 
100 votes, voting together with the Common Stock. In the event of any merger, 
consolidation or other transaction in which the Common Stock is changed or 
exchanged, each share of Series A Participating Preferred Stock will be 
entitled to receive 100 times the amount received per share of Common Stock. 
These rights are protected by customary anti-dilution provisions.

     Because of the nature of the dividend, liquidation and voting rights of 
the shares of Series A Participating Preferred Stock, the value of the one 
one-hundredth interest in a share of Series A Participating Preferred Stock 
purchasable upon exercise of each Right should approximate the value of one 
share of Common Stock.

CERTAIN ANTI-TAKEOVER EFFECTS

     The Rights have certain anti-takeover effects.  The Rights will cause 
substantial dilution to a person or group that attempts to acquire the 
Company without conditioning the offer on the Rights being redeemed or a 
substantial number of Rights being acquired.  However, the Rights should not 
interfere with any tender offer or merger approved by the Company (other than 
with an Acquiring Person) because the Rights do not become exercisable in the 
event of a Permitted Offer or other acquisition exempted by the Company's 
Board.

     The Rights are not intended to prevent a takeover of the Company and 
will not do so. The Rights may be redeemed by the Company at $0.001 per Right 
within 10 business days (or such later date as may be determined by a 
majority of the Board of Directors) after the accumulation of 20% or more of 
the Company's stock by a single acquirer or group.  In addition, the Rights 
do not become exercisable in the event of an accumulation exempted by the 
Board of Directors. Accordingly, the Rights should not interfere with any 
merger or business combination approved by the Board of Directors.

     The issuance of the Rights does not affect the financial condition or 
business plans of the Company.  The issuance of the Rights has no dilutive 
effect, will not affect reported earnings per share, should not be taxable to 
the Company or to its shareholders, and will not change the way in which the 
Company's stock is presently traded.

     However, the Rights may have the effect of rendering more difficult or 
discouraging an acquisition of the Company deemed coercive and undesirable by 
the Board of Directors.  The Rights may cause substantial dilution to a 
person or group that attempts to acquire the Company on terms or in a manner 
not approved by the Company's Board of Directors except pursuant to an offer 
conditioned upon the negation, purchase or redemption of the Rights.
