Item 1.   Description of Registrant's Securities to be Registered.

          On February 9, 1996, the Board of Directors of Cadence Design
Systems, Inc. (the "Company") declared a dividend of one preferred share
purchase right (a "Right") for each outstanding share of common stock, par
value $.01 per share, of the Company (the "Common Stock").  The dividend is
payable on February 20, 1996 (the "Record Date") to the stockholders of record
on that date.  Each Right entitles the registered holder to purchase from the
Company one one-thousandth of a share of Series A Junior Participating
Preferred Stock, par value $.01 per share (the "Preferred Stock") of the
Company at a price of $240 per one one-thousandth of a share of Preferred Stock
(the "Purchase Price"), subject to adjustment.  The description and terms of
the Rights are set forth in a Rights Agreement dated as of February 9, 1996, as
the same may be amended from time to time (the "Rights Agreement"), between the
Company and Harris Trust and Savings Bank, as Rights Agent (the "Rights
Agent").  The rights issued under the old amended and restated rights
agreement, dated as of June 20, 1989, between the Company and the Rights Agent
expired at the close of business on February 9, 1996.

          Until the earlier to occur of (i) 10 days following a public
announcement that a person or group of affiliated or associated persons (an
"Acquiring Person") have acquired beneficial ownership of 15% or more of the
outstanding shares of Common Stock or (ii) 10 business days (or such later date
as may be determined by action of the Board of Directors prior to such time as
any person or group of affiliated persons becomes an Acquiring Person)
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 15% or more of the outstanding
shares of Common Stock (the earlier of such dates being called the
"Distribution Date"), the Rights will be evidenced, with respect to any of the
Common Stock certificates outstanding as of the Record Date, by such Common
Stock certificate together with a copy of this Summary of Rights.

          The Rights Agreement provides that, until the Distribution Date (or
earlier redemption or expiration of the Rights), the Rights will be transferred
with and only with the Common Stock.  Until the Distribution Date (or earlier
redemption or expiration of the Rights), new Common Stock certificates issued
after the Record Date upon transfer or new issuances of Common Stock will
contain a notation incorporating the Rights Agreement by reference.  Until the
Distribution Date (or earlier redemption or expiration of the Rights), the
surrender for transfer of any certificates for shares of Common Stock
outstanding as of the Record Date, even without such notation or a copy of this
Summary of Rights, will also constitute the transfer of the Rights associated
with the shares of Common Stock represented by such certificate.  As soon as
practicable following the Distribution Date, separate certificates evidencing
the Rights ("Right 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 Right Certificates alone will evidence the Rights.

          The Rights are not exercisable until the Distribution Date.  The
Rights will expire on February 9, 2006 (the "Final Expiration Date"), unless
the Final Expiration Date is extended or unless the Rights are earlier redeemed
or exchanged by the Company, in each case as described below.

          The Purchase Price payable, and the number of shares of Preferred
Stock or other securities or property issuable, upon exercise of the Rights are
<PAGE>
subject to adjustment from time to time to prevent dilution (i) in the event of
a stock dividend on, or a subdivision, combination or reclassification of, the
Preferred Stock, (ii) upon the grant to holders of the Preferred Stock of
certain rights or warrants to subscribe for or purchase Preferred Stock at a
price, or securities convertible into Preferred Stock with a conversion price,
less than the then-current market price of the Preferred Stock or (iii) upon
the distribution to holders of the Preferred Stock of evidences of indebtedness
or assets (excluding regular periodic cash dividends or dividends payable in
Preferred Stock) or of subscription rights or warrants (other than those
referred to above).

          The number of outstanding Rights are also subject to adjustment in
the event of a stock split of the Common Stock or a stock dividend on the
Common Stock payable in shares of Common Stock or subdivisions, consolidations
or combinations of the Common Stock occurring, in any such case, prior to the
Distribution Date.

          Shares of Preferred Stock purchasable upon exercise of the Rights
will not be redeemable.  Each share of Preferred Stock will be entitled, when,
as and if declared, to a minimum preferential quarterly dividend payment of $1
per share but will be entitled to an aggregate dividend of 1000 times the
dividend declared per share of Common Stock.  In the event of liquidation, the
holders of the Preferred Stock will be entitled to a minimum preferential
liquidation payment of $1000 per share (plus any accrued but unpaid dividends)
but will be entitled to an aggregate payment of 1000 times the payment made per
share of Common Stock.  Each share of Preferred Stock will have 1000 votes,
voting together with the Common Stock.  Finally, in the event of any merger,
consolidation or other transaction in which shares of Common Stock are
converted or exchanged, each share of Preferred Stock will be entitled to
receive 1000 times the amount received per share of Common Stock.  These rights
are protected by customary antidilution provisions.

          Because of the nature of the Preferred Stock's dividend, liquidation
and voting rights, the value of the one one-thousandth interest in a share of
Preferred Stock purchasable upon exercise of each Right should approximate the
value of one share of Common Stock.

          In the event that any person or group of affiliated or associated
persons becomes an Acquiring Person, each holder of a Right, other than Rights
beneficially owned by the Acquiring Person (which will thereupon become void),
will thereafter have the right to receive upon exercise of a Right at the then
current exercise price of the Right, that number of shares of Common Stock
having a market value of two times the exercise price of the Right.

          In the event that, after a person or group has become an Acquiring
Person, the Company is acquired in a merger or other business combination
transaction or 50% or more of its consolidated assets or earning power are
sold, proper provision will be made so that each holder of a Right (other than
Rights beneficially owned by an Acquiring Person which will have become void)
will thereafter have the right to receive, upon the exercise thereof at the
then current exercise price of the Right, that number of shares of common stock
of the person with whom the Company has engaged in the foregoing transaction
(or its parent), which number of shares at the time of such transaction will
have a market value of two times the exercise price of the Right.  

          At any time after any person or group becomes an Acquiring Person and
prior to the acquisition by such person or group of 50% or more of the
<PAGE>
outstanding shares of Common Stock or the occurrence of an event described in
the prior paragraph, the Board of Directors of the Company may exchange the
Rights (other than Rights owned by such person or group which will have become
void), in whole or in part, at an exchange ratio of one share of Common Stock,
or one one-thousandth of a share of Preferred Stock (or of a share of a class
or series of the Company's preferred stock having equivalent rights,
preferences and privileges), per Right (subject to adjustment).

          With certain exceptions, no adjustment in the Purchase Price will be
required until cumulative adjustments require an adjustment of at least 1% in
such Purchase Price.  No fractional shares of Preferred Stock will be issued
(other than fractions which are integral multiples of one one-thousandth of a
share of Preferred Stock, which may, at the election of the Company, be
evidenced by depositary receipts) and in lieu thereof, an adjustment in cash
will be made based on the market price of the Preferred Stock on the last
trading day prior to the date of exercise.

          At any time prior to the time an Acquiring Person becomes such, the
Board of Directors of the Company may redeem the Rights in whole, but not in
part, at a price of $.01 per Right (the "Redemption Price").  The redemption of
the Rights may be made effective at such time, on such basis and with such
conditions as the Board of Directors in its sole discretion may establish. 
Immediately upon any redemption of the Rights, the right to exercise the Rights
will terminate and the only right of the holders of Rights will be to receive
the Redemption Price.

          For so long as the Rights are then redeemable, the Company may,
except with respect to the redemption price, amend the Rights in any manner. 
After the Rights are no longer redeemable, the Company may, except with respect
to the redemption price, amend the Rights in any manner that does not adversely
affect the interests of holders of the Rights. 

          Until a Right is exercised, the holder thereof, as such, will have no
rights as a stockholder of the Company, including, without limitation, the
right to vote or to receive dividends.

          This summary description of the Rights does not purport to be
complete and is qualified in its entirety by reference to the Rights Agreement,
as the same may be amended from time to time, which is hereby incorporated
herein by reference.

          The Rights have been issued in place of the Company's previous common
share purchase rights issued in 1989.  The principal differences between the
old rights and the new Rights are (1) the new Rights are exercisable for shares
of Preferred Stock instead of Common Stock, (2) an increase in the exercise
price from $66.67 (as adjusted to reflect the Company's stock split) to $240
per share; (3) the reduction in the threshold percentage from 20% to 15%; and
(4) the elimination of a provision in the old rights plan permitting redemption
of the rights during the 10 days after a person or group becomes an Acquiring
Person.

                                RIGHTS AGREEMENT


          Agreement, dated as of February 9, 1996, between Cadence Design

Systems, Inc., a Delaware corporation (the "Company"), and Harris Trust and

Savings Bank, a national banking association (the "Rights Agent").

          The Board of Directors of the Company has authorized and declared a

dividend of one preferred share purchase right (a "Right") for each share of

Common Stock (as hereinafter defined) of the Company outstanding as of the

close of business (as defined below) on February 20, 1996 (the "Record Date"),

each Right representing the right to purchase one one-thousandth (subject to

adjustment) of a share of Preferred Stock (as hereinafter defined), upon the

terms and subject to the conditions herein set forth, and has further

authorized and directed the issuance of one Right (subject to adjustment as

provided herein) with respect to each share of Common Stock that shall become

outstanding between the Record Date and the earliest of the Distribution Date,

the Redemption Date and the Final Expiration Date (as such terms are

hereinafter defined); provided, however, that Rights may be issued with respect

to shares of Common Stock that shall become outstanding after the Distribution

Date and prior to the Redemption Date and the Final Expiration Date in

accordance with Section 22. 

          Accordingly, in consideration of the premises and the mutual

agreements herein set forth, the parties hereby agree as follows:

          Section 1.  Certain Definitions.  For purposes of this Agreement, the

following terms have the meaning indicated:

          (a)  "Acquiring Person" shall mean any Person (as such term is

     hereinafter defined) who or which shall be the Beneficial Owner (as such

     term is hereinafter defined) of 15% or more of the shares of Common Stock

     then outstanding, but shall not include an Exempt Person (as such term is
<PAGE>
     hereinafter defined); provided, however, that if the Board of Directors of

     the Company determines in good faith that a Person who would otherwise be

     an "Acquiring Person" has become such inadvertently (including, without

     limitation, because (i) such Person was unaware that it beneficially owned

     a percentage of Common Stock that would otherwise cause such Person to be

     an "Acquiring Person" or (ii) such Person was aware of the extent of its

     Beneficial Ownership of Common Stock but had no actual knowledge of the

     consequences of such Beneficial Ownership under this Rights Agreement) and

     without any intention of changing or influencing control of the Company,

     and such Person, as promptly as practicable divested or divests himself or

     itself of Beneficial Ownership of a sufficient number of shares of Common

     Stock so that such Person would no longer be an Acquiring Person, then

     such Person shall not be deemed to be or to have become an "Acquiring

     Person" for any purposes of this Agreement.  Notwithstanding the

     foregoing, (i) if a Person would be deemed an Acquiring Person upon the

     adoption of this Agreement because of Beneficial Ownership of between 15%

     and 20% of the shares of stock on such date, such Person will not be

     deemed an Acquiring Person for any purposes of this Agreement unless and

     until such Person acquires Beneficial Ownership of any additional shares

     of Common Stock after the adoption of this Agreement unless upon the

     consummation of the acquisition of such additional shares of Common Stock

     such Person does not beneficially own 15% or more of the shares of Common

     Stock then outstanding and (ii) no Person shall become an "Acquiring

     Person" as the result of an acquisition of shares of Common Stock by the

     Company which, by reducing the number of shares outstanding, increases the

     proportionate number of shares beneficially owned by such Person to 15% or

     more of the shares of Common Stock then outstanding, provided, however,

     that if a Person shall become the Beneficial Owner of 15% or more of the

     shares of Common Stock then outstanding by reason of such share
<PAGE>
     acquisitions by the Company and thereafter become the Beneficial Owner of

     any additional shares of Common Stock, then such Person shall be deemed to

     be an "Acquiring Person" unless upon the consummation of the acquisition

     of such additional shares of Common Stock such Person does not own 15% or

     more of the shares of Common Stock then outstanding.   The phrase "then

     outstanding", when used with reference to a Person's Beneficial Ownership

     of securities of the Company, shall mean the number of such securities

     then issued and outstanding together with the number of such securities

     not then actually issued and outstanding which such Person would be deemed

     to own beneficially hereunder.  

          (b)  "Affiliate" and "Associate" shall have the respective meanings

     ascribed to such terms in Rule 12b-2 of the General Rules and Regulations

     under the Securities Exchange Act of 1934, as amended (the "Exchange

     Act"), as in effect on the date of this Agreement.

          (c)  A Person shall be deemed the "Beneficial Owner" of, shall be

     deemed to have "Beneficial Ownership" of and shall be deemed to

     "beneficially own" any securities:

               (i)  which such Person or any of such Person's Affiliates or

          Associates is deemed to beneficially own, directly or indirectly

          within the meaning of Rule 13d-3 of the General Rules and Regulations

          under the Exchange Act as in effect on the date of this Agreement;

              (ii)  which such Person or any of such Person's Affiliates or

          Associates has (A) the right to acquire (whether such right is

          exercisable immediately or only after the passage of time) pursuant

          to any agreement, arrangement or understanding (other than customary

          agreements with and between underwriters and selling group members

          with respect to a bona fide public offering of securities), or upon

          the exercise of conversion rights, exchange rights, rights, warrants

          or options, or otherwise; provided, however, that a Person shall not
<PAGE>
          be deemed the Beneficial Owner of, or to beneficially own, (x)

          securities tendered pursuant to a tender or exchange offer made by or

          on behalf of such Person or any of such Person's Affiliates or

          Associates until such tendered securities are accepted for purchase,

          (y) securities which such Person has a right to acquire on the

          exercise of Rights at any time prior to the time a Person becomes an

          Acquiring Person or (z) securities issuable upon exercise of Rights

          from and after the time a Person becomes an Acquiring Person if such

          Rights were acquired by such Person or any of such Person's

          Affiliates or Associates prior to the Distribution Date or pursuant

          to Section 3(a) or Section 22 hereof ("original Rights") or pursuant

          to Section 11(i) or Section 11(n) with respect to an adjustment to

          original Rights; or (B) the right to vote pursuant to any agreement,

          arrangement or understanding; provided, however, that a Person shall

          not be deemed the Beneficial Owner of, or to beneficially own, any

          security by reason of such agreement, arrangement or understanding if

          the agreement, arrangement or understanding to vote such security (1)

          arises solely from a revocable proxy or consent given to such Person

          in response to a public proxy or consent solicitation made pursuant

          to, and in accordance with, the applicable rules and regulations

          promulgated under the Exchange Act and (2) is not also then

          reportable on Schedule 13D under the Exchange Act (or any comparable

          or successor report); or

             (iii)  which are beneficially owned, directly or indirectly, by

          any other Person with which such Person or any of such Person's

          Affiliates or Associates has any agreement, arrangement or

          understanding (other than customary agreements with and between

          underwriters and selling group members with respect to a bona fide

          public offering of securities) for the purpose of acquiring, holding,
<PAGE>
          voting (except to the extent contemplated by the proviso to Section

          1(c)(ii)(B)) or disposing of any securities of the Company.

          (d)  "Business Day" shall mean any day other than a Saturday, a

     Sunday, or a day on which banking institutions in the State of New York,

     or the State in which the principal office of the Rights Agent is located,

     are authorized or obligated by law or executive order to close.

          (e)  "close of business" on any given date shall mean 5:00 P.M., New

     York City time, on such date; provided, however, that if such date is not

     a Business Day it shall mean 5:00 P.M., New York City time, on the next

     succeeding Business Day.

          (f)  "Common Stock" when used with reference to the Company shall

     mean the common stock, presently par value $.01 per share, of the Company. 

     "Common Stock" when used with reference to any Person other than the

     Company shall mean the capital stock (or, in the case of an unincorporated

     entity, the equivalent equity interest) with the greatest voting power of

     such other Person or, if such other Person is a subsidiary of another

     Person, the Person or Persons which ultimately control such

     first-mentioned Person.

          (g)  "Distribution Date" shall have the meaning set forth in Section

     3 hereof.

          (h)  "Exempt Person" shall mean the Company, any Subsidiary (as such

     term is hereinafter defined) of the Company, any employee benefit plan of

     the Company or of any Subsidiary of the Company, or any entity or trustee

     holding Common Stock for or pursuant to the terms of any such plan or for

     the purpose of funding any such plan or funding other employee benefits

     for employees of the Company or of any Subsidiary of the Company.

          (i)  "Final Expiration Date" shall have the meaning set forth in

     Section 7 hereof.
<PAGE>
          (j)  "New York Stock Exchange" shall mean the stock market operated

     by the New York Stock Exchange, Inc. 

          (k)  "Person" shall mean any individual, firm, corporation or other

     entity, and shall include any successor (by merger or otherwise) of such

     entity.

          (l)  "Preferred Stock" shall mean the Series A Junior Participating

     Preferred Stock, par value $.01 per share, of the Company having the

     rights and preferences set forth in the Form of Certificate of

     Designations attached to this Agreement as Exhibit A.

          (m)  "Redemption Date" shall have the meaning set forth in Section 7

     hereof.

          (n)  "Securities Act" shall mean the Securities Act of 1933, as

     amended.

          (o)  "Stock Acquisition Date" shall mean the first date of public

     announcement (which for purposes of this definition, shall include,

     without limitation, a report filed pursuant to Section 13(d) of the

     Exchange Act) by the Company or an Acquiring Person that an Acquiring

     Person has become such or such earlier date as a majority of the Board of

     Directors shall become aware of the existence of an Acquiring Person.

          (p)  "Subsidiary" of any Person shall mean any corporation or other

     entity of which securities or other ownership interests having ordinary

     voting power sufficient to elect a majority of the board of directors or

     other persons performing similar functions are beneficially owned,

     directly or indirectly, by such Person, and any corporation or other

     entity that is otherwise controlled by such Person.

          Section 2.  Appointment of Rights Agent.  The Company hereby appoints

the Rights Agent to act as agent for the Company and the holders of the Rights

(who, in accordance with Section 3 hereof, shall prior to the Distribution Date

also be the holders of Common Stock) in accordance with the terms and
<PAGE>
conditions hereof, and the Rights Agent hereby accepts such appointment.  The

Company may from time to time appoint such co-Rights Agents as it may deem

necessary or desirable.

          Section 3.  Issue of Right Certificates.  (a)  Until the earlier of

(i) the tenth day after the Stock Acquisition Date or (ii) the tenth business

day (or such later date as may be determined by action of the Board of

Directors prior to such time as any Person becomes an Acquiring Person) after

the date of the commencement by any Person (other than an Exempt Person) of, or

of the first public announcement of the intention of such Person (other than an

Exempt Person) to commence, a tender or exchange offer the consummation of

which would result in any Person becoming the Beneficial Owner of shares of

Common Stock aggregating 15% or more of the Common Stock then outstanding

(including any such date which is after the date of this Agreement and prior to

the issuance of the Rights; the earlier of such dates being herein referred to

as the "Distribution Date"), (x) the Rights will be evidenced (subject to the

provisions of Section 3(b) hereof) by the certificates for Common Stock

registered in the names of the holders thereof and not by separate Right

Certificates, and (y) the Rights will be transferable only in connection with

the transfer of Common Stock.  As soon as practicable after the Distribution

Date, the Company will prepare and execute, the Rights Agent will countersign,

and the Company will send or cause to be sent (and the Rights Agent will, if

requested, send) by first-class, insured, postage-prepaid mail, to each record

holder of Common Stock as of the close of business on the Distribution Date

(other than any Acquiring Person or any Associate or Affiliate of an Acquiring

Person), at the address of such holder shown on the records of the Company, a

Right Certificate, in substantially the form of Exhibit B hereto (a "Right

Certificate"), evidencing one Right (subject to adjustment as provided herein)

for each share of Common Stock so held.  As of the Distribution Date, the

Rights will be evidenced solely by such Right Certificates.
<PAGE>
          (b)  On the Record Date, or as soon as practicable thereafter, the

Company will send a copy of a Summary of Rights to Purchase Shares of Preferred

Stock, in substantially the form of Exhibit C hereto (the "Summary of Rights"),

by first-class, postage-prepaid mail, to each record holder of Common Stock as

of the close of business on the Record Date (other than any Acquiring Person or

any Associate or Affiliate of any Acquiring Person), at the address of such

holder shown on the records of the Company.  With respect to certificates for

Common Stock outstanding as of the Record Date, until the Distribution Date,

the Rights will be evidenced by such certificates registered in the names of

the holders thereof together with the Summary of Rights.  Until the Distribu-

tion Date (or the earlier of the Redemption Date or the Final Expiration Date),

the surrender for transfer of any certificate for Common Stock outstanding on

the Record Date, with or without a copy of the Summary of Rights, shall also

constitute the transfer of the Rights associated with the Common Stock

represented thereby.

          (c)  Certificates issued for Common Stock (including, without

limitation, upon transfer of outstanding Common Stock, disposition of Common

Stock out of treasury stock or issuance or reissuance of Common Stock out of

authorized but unissued shares) after the Record Date but prior to the earliest

of the Distribution Date, the Redemption Date or the Final Expiration Date

shall have impressed on, printed on, written on or otherwise affixed to them

the following legend:

          This certificate also evidences and entitles the holder
          hereof to certain rights as set forth in a Rights Agreement
          between Cadence Design Systems, Inc. and Harris Trust and
          Savings Bank, dated as of February 9, 1996 as the same may
          be amended from time to time (the "Rights Agreement"), the
          terms of which are hereby incorporated herein by reference
          and a copy of which is on file at the principal executive
          offices of Cadence Design Systems, Inc..  Under certain
          circumstances, as set forth in the Rights Agreement, such
          Rights will be evidenced by separate certificates and will
          no longer be evidenced by this certificate.  Cadence Design
          Systems, Inc. will mail to the holder of this certificate a
          copy of the Rights Agreement without charge after receipt
<PAGE>
          of a written request therefor.  Under certain
          circumstances, as set forth in the Rights Agreement, Rights
          owned by or transferred to any Person who becomes an
          Acquiring Person (as defined in the Rights Agreement) and
          certain transferees thereof will become null and void and
          will no longer be transferable.

With respect to such certificates containing the foregoing legend, until the

Distribution Date, the Rights associated with the Common Stock represented by

such certificates shall be evidenced by such certificates alone, and the

surrender for transfer of any such certificate, except as otherwise provided

herein, shall also constitute the transfer of the Rights associated with the

Common Stock represented thereby.  In the event that the Company purchases or

otherwise acquires any Common Stock after the Record Date but prior to the

Distribution Date, any Rights associated with such Common Stock shall be deemed

cancelled and retired so that the Company shall not be entitled to exercise any

Rights associated with the Common Stock which are no longer outstanding.  

          Notwithstanding this paragraph (c), the omission of a legend shall

not affect the enforceability of any part of this Agreement or the rights of

any holder of the Rights.

          Section 4.  Form of Right Certificates.  The Right Certificates (and

the forms of election to purchase shares and of assignment to be printed on the

reverse thereof) shall be substantially in the form set forth in Exhibit B

hereto and may have such marks of identification or designation and such

legends, summaries or endorsements printed thereon as the Company may deem

appropriate and as are not inconsistent with the provisions of this Agreement,

or as may be required to comply with any applicable law or with any rule or

regulation made pursuant thereto or with any rule or regulation of the New York 

Stock Exchange or of any other stock exchange or automated quotation system on

which the Rights may from time to time be listed, or to conform to usage. 

Subject to the provisions of Sections 11, 13 and 22 hereof, the Right

Certificates shall entitle the holders thereof to purchase such number of one
<PAGE>
one-thousandths of a share of Preferred Stock as shall be set forth therein at

the price per one one-thousandth of a share of Preferred Stock set forth

therein (the "Purchase Price"), but the number of such one one-thousandths of a

share of Preferred Stock and the Purchase Price shall be subject to adjustment

as provided herein.

          Section 5.  Countersignature and Registration.  (a)  The Right

Certificates shall be executed on behalf of the Company by the Chairman of

the Board of Directors, the President, any of the Vice Presidents, the

Treasurer or the Controller of the Company, either manually or by facsimile

signature, shall have affixed thereto the Company's seal or a facsimile

thereof, and shall be attested by the Secretary or an Assistant Secretary of

the Company, either manually or by facsimile signature.  The Right Certificates

shall be manually countersigned by the Rights Agent and shall not be valid for

any purpose unless countersigned.  In case any officer of the Company who shall

have signed any of the Right Certificates shall cease to be such officer of the

Company before countersignature by the Rights Agent and issuance and delivery

by the Company, such Right Certificates, nevertheless, may be countersigned by

the Rights Agent and issued and delivered by the Company with the same force

and effect as though the Person who signed such Right Certificates had not

ceased to be such officer of the Company; and any Right Certificate may be

signed on behalf of the Company by any Person who, at the actual date of the

execution of such Right Certificate, shall be a proper officer of the Company

to sign such Right Certificate, although at the date of the execution of this

Agreement any such Person was not such an officer.

          (b)  Following the Distribution Date, the Rights Agent will keep or

cause to be kept, at an office or agency designated for such purpose, books for

registration and transfer of the Right Certificates issued hereunder.  Such

books shall show the names and addresses of the respective holders of the Right
<PAGE>
Certificates, the number of Rights evidenced on its face by each of the Right

Certificates and the date of each of the Right Certificates.

          Section 6.  Transfer, Split Up, Combination and Exchange of Right

Certificates; Mutilated, Destroyed, Lost or Stolen Right Certificates.  (a) 

Subject to the provisions of Sections 7(e), 11(a)(ii) and 14 hereof, at any

time after the close of business on the Distribution Date, and prior to the

close of business on the earlier of the Redemption Date or the Final Expiration

Date, any Right Certificate or Right Certificates may be transferred, split up,

combined or exchanged for another Right Certificate or Right Certificates,

entitling the registered holder to purchase a like number of one

one-thousandths of a share of Preferred Stock as the Right Certificate or Right

Certificates surrendered then entitled such holder to purchase.  Any registered

holder desiring to transfer, split up, combine or exchange any Right

Certificate or Right Certificates shall make such request in writing delivered

to the Rights Agent, and shall surrender the Right Certificate or Right

Certificates to be transferred, split up, combined or exchanged at the office

or agency of the Rights Agent designated for such purpose.  Thereupon the

Rights Agent shall countersign and deliver to the Person entitled thereto a

Right Certificate or Right Certificates, as the case may be, as so requested. 

The Company may require payment of a sum sufficient to cover any tax or

governmental charge that may be imposed in connection with any transfer, split

up, combination or exchange of Right Certificates.

          (b)  Subject to the provisions of Section 11(a)(ii) hereof, at any

time after the Distribution Date and prior to the close of business on the

earlier of the Redemption Date or the Final Expiration Date, upon receipt by

the Company and the Rights Agent of evidence reasonably satisfactory to them of

the loss, theft, destruction or mutilation of a Right Certificate, and, in case

of loss, theft or destruction, of indemnity or security reasonably satisfactory

to them, and, at the Company's request, reimbursement to the Company and the
<PAGE>
Rights Agent of all reasonable expenses incidental thereto, and upon surrender

to the Rights Agent and cancellation of the Right Certificate if mutilated, the

Company will make and deliver a new Right Certificate of like tenor to the

Rights Agent for delivery to the registered holder in lieu of the Right

Certificate so lost, stolen, destroyed or mutilated.

          Section 7.  Exercise of Rights, Purchase Price; Expiration Date of

Rights.  (a)  Except as otherwise provided herein, the Rights shall become

exercisable on the Distribution Date, and thereafter the registered holder of

any Right Certificate may, subject to Section 11(a)(ii) hereof and except as

otherwise provided herein, exercise the Rights evidenced thereby in whole or in

part upon surrender of the Right Certificate, with the form of election to

purchase on the reverse side thereof duly executed, to the Rights Agent at the

office or agency of the Rights Agent designated for such purpose, together with

payment of the Purchase Price for each one one-thousandth of a share of

Preferred Stock as to which the Rights are exercised, at any time which is both

after the Distribution Date and prior to the earliest of (i) the close of

business on February 9, 2006 (the "Final Expiration Date"), (ii) the time at

which the Rights are redeemed as provided in Section 23 hereof (the "Redemption

Date") or (iii) the time at which such Rights are exchanged as provided in

Section 24 hereof.

          (b)  The Purchase Price shall be initially $240 for each one

one-thousandth of a share of Preferred Stock purchasable upon the exercise of a

Right.  The Purchase Price and the number of one one-thousandths of a share of

Preferred Stock or other securities or property to be acquired upon exercise of

a Right shall be subject to adjustment from time to time as provided in

Sections 11 and 13 hereof and shall be payable in lawful money of the United

States of America in accordance with paragraph (c) of this Section 7.

          (c)  Except as otherwise provided herein, upon receipt of a Right

Certificate representing exercisable Rights, with the form of election to
<PAGE>
purchase duly executed, accompanied by payment of the aggregate Purchase Price

for the shares of Preferred Stock to be purchased and an amount equal to any

applicable transfer tax required to be paid by the holder of such Right

Certificate in accordance with Section 9 hereof, in cash or by certified check,

cashier's check or money order payable to the order of the Company, the Rights

Agent shall thereupon promptly (i) (A) requisition from any transfer agent of

the Preferred Stock certificates for the number of shares of Preferred Stock to

be purchased and the Company hereby irrevocably authorizes its transfer agent

to comply with all such requests, or (B) requisition from the depositary agent

depositary receipts representing interests in such number of one

one-thousandths of a share of Preferred Stock as are to be purchased (in which

case certificates for the Preferred Stock represented by such receipts shall be

deposited by the transfer agent with the depositary agent) and the Company

hereby directs the depositary agent to comply with such request, (ii) when

appropriate, requisition from the Company the amount of cash to be paid in lieu

of issuance of fractional shares in accordance with Section 14 hereof, (iii)

promptly after receipt of such certificates or depositary receipts, cause the

same to be delivered to or upon the order of the registered holder of such

Right Certificate, registered in such name or names as may be designated by

such holder and (iv) when appropriate, after receipt, promptly deliver such

cash to or upon the order of the registered holder of such Right Certificate.

          (d)  Except as otherwise provided herein, in case the registered

holder of any Right Certificate shall exercise less than all the Rights

evidenced thereby, a new Right Certificate evidencing Rights equivalent to the

exercisable Rights remaining unexercised shall be issued by the Rights Agent to

the registered holder of such Right Certificate or to his duly authorized

assigns, subject to the provisions of Section 14 hereof.

          (e)  Notwithstanding anything in this Agreement to the contrary,

neither the Rights Agent nor the Company shall be obligated to undertake any
<PAGE>
action with respect to a registered holder of Rights upon the occurrence of any

purported transfer or exercise of Rights pursuant to Section 6 hereof or this

Section 7 unless such registered holder shall have (i) completed and signed the

certificate contained in the form of assignment or election to purchase set

forth on the reverse side of the Rights Certificate surrendered for such

transfer or exercise and (ii) provided such additional evidence of the identity

of the Beneficial Owner (or former Beneficial Owner) thereof as the Company

shall reasonably request. 

          Section 8.  Cancellation and Destruction of Right Certificates.  All

Right Certificates surrendered for the purpose of exercise, transfer, split up,

combination or exchange shall, if surrendered to the Company or to any of its

agents, be delivered to the Rights Agent for cancellation or in cancelled form,

or, if surrendered to the Rights Agent, shall be cancelled by it, and no Right

Certificates shall be issued in lieu thereof except as expressly permitted by

any of the provisions of this Agreement.  The Company shall deliver to the

Rights Agent for cancellation and retirement, and the Rights Agent shall so

cancel and retire, any other Right Certificate purchased or acquired by the

Company otherwise than upon the exercise thereof.  The Rights Agent shall

deliver all cancelled Right Certificates to the Company, or shall, at the

written request of the Company, destroy such cancelled Right Certificates, and

in such case shall deliver a certificate of destruction thereof to the Company.

          Section 9.  Availability of Shares of Preferred Stock.  (a)  The

Company covenants and agrees that it will cause to be reserved and kept

available out of its authorized and unissued shares of Preferred Stock or any

shares of Preferred Stock held in its treasury, the number of shares of

Preferred Stock that will be sufficient to permit the exercise in full of all

outstanding Rights.

          (b)  So long as the shares of Preferred Stock (and, following the

time that a Person becomes an Acquiring Person, shares of Common Stock and
<PAGE>
other securities) issuable upon the exercise of Rights may be listed or

admitted to trading on the New York Stock Exchange or listed on any other

national securities exchange or quotation system, the Company shall use its

best efforts to cause, from and after such time as the Rights become

exercisable, all shares reserved for such issuance to be listed or admitted to

trading on the New York Stock Exchange or listed on any other exchange or

quotation system upon official notice of issuance upon such exercise.

          (c)  From and after such time as the Rights become exercisable, the

Company shall use its best efforts, if then necessary to permit the issuance of

shares of Preferred Stock (and following the time that a Person first becomes

an Acquiring Person, shares of Common Stock and other securities) upon the

exercise of Rights, to register and qualify such shares of Preferred Stock (and

following the time that a Person first becomes an Acquiring Person, shares of

Common Stock and other securities) under the Securities Act and any applicable

state securities or "Blue Sky" laws (to the extent exemptions therefrom are not

available), cause such registration statement and qualifications to become

effective as soon as possible after such filing and keep such registration and

qualifications effective until the earlier of the date as of which the Rights

are no longer exercisable for such securities and the Final Expiration Date. 

The Company may temporarily suspend, for a period of time not to exceed 90

days, the exercisability of the Rights in order to prepare and file a

registration statement under the Securities Act and permit it to become

effective.  Upon any such suspension, the Company shall issue a public

announcement stating that the exercisability of the Rights has been temporarily

suspended, as well as a public announcement at such time as the suspension is

no longer in effect.  Notwithstanding any provision of this Agreement to the

contrary, the Rights shall not be exercisable in any jurisdiction unless the

requisite qualification in such jurisdiction shall have been obtained and until
<PAGE>
a registration statement under the Securities Act (if required) shall have been

declared effective.

          (d)  The Company covenants and agrees that it will take all such

action as may be necessary to ensure that all shares of Preferred Stock (and,

following the time that a Person becomes an Acquiring Person, shares of Common

Stock and other securities) delivered upon exercise of Rights shall, at the

time of delivery of the certificates therefor (subject to payment of the

Purchase Price), be duly and validly authorized and issued and fully paid and

nonassessable shares.

          (e)  The Company further covenants and agrees that it will pay when

due and payable any and all federal and state transfer taxes and charges which

may be payable in respect of the issuance or delivery of the Right Certificates

or of any shares of Preferred Stock (or shares of Common Stock or other

securities) upon the exercise of Rights.  The Company shall not, however, be

required to pay any transfer tax which may be payable in respect of any

transfer or delivery of Right Certificates to a Person other than, or the is-

suance or delivery of certificates or depositary receipts for the Preferred

Stock (or shares of Common Stock or other securities) in a name other than that

of, the registered holder of the Right Certificate evidencing Rights

surrendered for exercise or to issue or deliver any certificates or depositary

receipts for Preferred Stock (or shares of Common Stock or other securities)

upon the exercise of any Rights until any such tax shall have been paid (any

such tax being payable by that holder of such Right Certificate at the time of

surrender) or until it has been established to the Company's reasonable

satisfaction that no such tax is due.

          Section 10.  Preferred Stock Record Date.  Each Person in whose name

any certificate for Preferred Stock is issued upon the exercise of Rights shall

for all purposes be deemed to have become the holder of record of the shares of

Preferred Stock represented thereby on, and such certificate shall be dated,
<PAGE>
the date upon which the Right Certificate evidencing such Rights was duly

surrendered and payment of the Purchase Price (and any applicable transfer

taxes) was made; provided, however, that if the date of such surrender and

payment is a date upon which the Preferred Stock transfer books of the Company

are closed, such Person shall be deemed to have become the record holder of

such shares on, and such certificate shall be dated, the next succeeding

Business Day on which the Preferred Stock transfer books of the Company are

open.  Prior to the exercise of the Rights evidenced thereby, the holder of a

Right Certificate shall not be entitled to any rights of a holder of Preferred

Stock for which the Rights shall be exercisable, including, without limitation,

the right to vote or to receive dividends or other distributions, and shall not

be entitled to receive any notice of any proceedings of the Company, except as

provided herein.

          Section 11.  Adjustment of Purchase Price, Number of Shares and

Number of Rights.  The Purchase Price, the number of shares of Preferred Stock

or other securities or property purchasable upon exercise of each Right and the

number of Rights outstanding are subject to adjustment from time to time as

provided in this Section 11.

          (a)  (i)  In the event the Company shall at any time after the date

          of this Agreement (A) declare a dividend on the Preferred Stock

          payable in shares of Preferred Stock, (B) subdivide the outstanding

          Preferred Stock, (C) combine the outstanding Preferred Stock into a

          smaller number of Preferred Stock or (D) issue any shares of its

          capital stock in a reclassification of the Preferred Stock (including

          any such reclassification in connection with a consolidation or

          merger in which the Company is the continuing or surviving

          corporation), except as otherwise provided in this Section 11(a), the

          Purchase Price in effect at the time of the record date for such

          dividend or of the effective date of such subdivision, combination or
<PAGE>
          reclassification, and the number and kind of shares of capital stock

          issuable on such date, shall be proportionately adjusted so that the

          holder of any Right exercised after such time shall be entitled to

          receive the aggregate number and kind of shares of capital stock

          which, if such Right had been exercised immediately prior to such

          date and at a time when the Preferred Stock transfer books of the

          Company were open, the holder would have owned upon such exercise and

          been entitled to receive by virtue of such dividend, subdivision,

          combination or reclassification; provided, however, that in no event

          shall the consideration to be paid upon the exercise of one Right be

          less than the aggregate par value of the shares of capital stock of

          the Company issuable upon exercise of one Right.

               (ii)  Subject to Section 24 of this Agreement and except as

          otherwise provided in this Section 11(a)(ii), in the event any Person

          becomes an Acquiring Person, each holder of a Right shall thereafter

          have the right to receive, upon exercise thereof at a price equal to

          the then current Purchase Price multiplied by the number of one

          one-thousandths of a share of Preferred Stock for which a Right is

          then exercisable, in accordance with the terms of this Agreement and

          in lieu of shares of Preferred Stock, such number of shares of Common

          Stock (or at the option of the Company, such number of one one-

          thousandths of shares of Preferred Stock) as shall equal the result

          obtained by (x) multiplying the then current Purchase Price by the

          number of one one-thousandths of a share of Preferred Stock for which

          a Right is then exercisable and dividing that product by (y) 50% of

          the then current per share market price of the Company's Common Stock

          (determined pursuant to Section 11(d) hereof) on the date of the

          occurrence of such event; provided, however, that the Purchase Price

          and the number of shares of Common Stock so receivable upon exercise
<PAGE>
          of a Right shall thereafter be subject to further adjustment as

          appropriate in accordance with Section 11(f) hereof.  Notwithstanding

          anything in this Agreement to the contrary, however, from and after

          the time (the "invalidation time") when any Person first becomes an

          Acquiring Person, any Rights that are beneficially owned by (x) any

          Acquiring Person (or any Affiliate or Associate of any Acquiring

          Person), (y) a transferee of any Acquiring Person (or any such

          Affiliate or Associate) who becomes a transferee after the

          invalidation time or (z) a transferee of any Acquiring Person (or any

          such Affiliate or Associate) who became a transferee prior to or

          concurrently with the invalidation time pursuant to either (I) a

          transfer from the Acquiring Person to holders of its equity

          securities or to any Person with whom it has any continuing

          agreement, arrangement or understanding regarding the transferred

          Rights or (II) a transfer which the Board of Directors has determined

          is part of a plan, arrangement or understanding which has the purpose

          or effect of avoiding the provisions of this paragraph, and

          subsequent transferees of such Persons, shall be void without any

          further action and any holder of such Rights shall thereafter have no

          rights whatsoever with respect to such Rights under any provision of

          this Agreement.  The Company shall use all reasonable efforts to

          ensure that the provisions of this Section 11(a)(ii) are complied

          with, but shall have no liability to any holder of Right Certificates

          or other Person as a result of its failure to make any determinations

          with respect to an Acquiring Person or its Affiliates, Associates or

          transferees hereunder.  From and after the invalidation time, no

          Right Certificate shall be issued pursuant to Section 3 or Section 6

          hereof that represents Rights that are or have become void pursuant

          to the provisions of this paragraph, and any Right Certificate
<PAGE>
          delivered to the Rights Agent that represents Rights that are or have

          become void pursuant to the provisions of this paragraph shall be

          cancelled.  From and after the occurrence of an event specified in

          Section 13(a) hereof, any Rights that theretofore have not been

          exercised pursuant to this Section 11(a)(ii) shall thereafter be

          exercisable only in accordance with Section 13 and not pursuant to

          this Section 11(a)(ii).

               (iii)  The Company may at its option substitute for a share of

          Common Stock issuable upon the exercise of Rights in accordance with

          the foregoing subparagraph (ii) such number or fractions of shares of

          Preferred Stock having an aggregate current market value equal to the

          current per share market price of a share of Common Stock.  In the

          event that there shall not be sufficient shares of Common Stock

          issued but not outstanding or authorized but unissued to permit the

          exercise in full of the Rights in accordance with the foregoing

          subparagraph (ii), the Board of Directors shall, to the extent

          permitted by applicable law and any material agreements then in

          effect to which the Company is a party (A) determine the excess of

          (1) the value of the shares of Common Stock issuable upon the

          exercise of a Right in accordance with the foregoing subparagraph

          (ii) (the "Current Value") over (2) the then current Purchase Price

          multiplied by the number of one one-thousandths of shares of

          Preferred Stock for which a Right was exercisable immediately prior

          to the time that the Acquiring Person became such (such excess, the

          "Spread"), and (B) with respect to each Right (other than Rights

          which have become void pursuant to Section 11(a)(ii)), make adequate

          provision to substitute for the shares of Common Stock issuable in

          accordance with subparagraph (ii) upon exercise of the Right and

          payment of the applicable Purchase Price, (1) cash, (2) a reduction
<PAGE>
          in the Purchase Price, (3) shares of Preferred Stock or other equity

          securities of the Company (including, without limitation, shares or

          fractions of shares of preferred stock which, by virtue of having

          dividend, voting and liquidation rights substantially comparable to

          those of the shares of Common Stock, are deemed in good faith by the

          Board of Directors to have substantially the same value as the shares

          of Common Stock (such shares of Preferred Stock and shares or

          fractions of shares of preferred stock are hereinafter referred to as

          "Common Stock equivalents"), (4) debt securities of the Company, (5)

          other assets, or (6) any combination of the foregoing, having a value

          which, when added to the value of the shares of Common Stock actually

          issued upon exercise of such Right, shall have an aggregate value

          equal to the Current Value (less the amount of any reduction in the

          Purchase Price), where such aggregate value has been determined by

          the Board of Directors upon the advice of a nationally recognized

          investment banking firm selected in good faith by the Board of

          Directors; provided, however, if the Company shall not make adequate

          provision to deliver value pursuant to clause (B) above within thirty

          (30) days following the date that the Acquiring Person became such

          (the "Section 11(a)(ii) Trigger Date"), then the Company shall be

          obligated to deliver, to the extent permitted by applicable law and

          any material agreements then in effect to which the Company is a

          party, upon the surrender for exercise of a Right and without

          requiring payment of the Purchase Price, shares of Common Stock (to

          the extent available), and then, if necessary, such number or

          fractions of shares of Preferred Stock (to the extent available) and

          then, if necessary, cash, which shares and/or cash have an aggregate

          value equal to the Spread.  If, upon the date any Person becomes an

          Acquiring Person, the Board of Directors shall determine in good
<PAGE>
          faith that it is likely that sufficient additional shares of Common

          Stock could be authorized for issuance upon exercise in full of the

          Rights, then, if the Board of Directors so elects, the thirty (30)

          day period set forth above may be extended to the extent necessary,

          but not more than ninety (90) days after the Section 11(a)(ii)

          Trigger Date, in order that the Company may seek stockholder approval

          for the authorization of such additional shares (such thirty (30) day

          period, as it may be extended, is herein called the "Substitution

          Period").  To the extent that the Company determines that some action

          need be taken pursuant to the second and/or third sentence of this

          Section 11(a)(iii), the Company (x) shall provide, subject to Section

          11(a)(ii) hereof and the last sentence of this Section 11(a)(iii)

          hereof, that such action shall apply uniformly to all outstanding

          Rights and (y) may suspend the exercisability of the Rights until the

          expiration of the Substitution Period in order to seek any

          authorization of additional shares and/or to decide the appropriate

          form of distribution to be made pursuant to such second sentence and

          to determine the value thereof.  In the event of any such suspension,

          the Company shall issue a public announcement stating that the

          exercisability of the Rights has been temporarily suspended, as well

          as a public announcement at such time as the suspension is no longer

          in effect.  For purposes of this Section 11(a)(iii), the value of the

          shares of Common Stock shall be the current per share market price

          (as determined pursuant to Section 11(d)(i)) on the Section 11(a)(ii)

          Trigger Date and the per share or fractional value of any "Common

          Stock equivalent" shall be deemed to equal the current per share

          market price of the Common Stock.  The Board of Directors of the

          Company may, but shall not be required to, establish procedures to

          allocate the right to receive shares of Common Stock upon the
<PAGE>
          exercise of the Rights among holders of Rights pursuant to this

          Section 11(a)(iii).

          (b)   In case the Company shall fix a record date for the issuance of

     rights, options or warrants to all holders of Preferred Stock entitling

     them (for a period expiring within 45 calendar days after such record

     date) to subscribe for or purchase Preferred Stock (or shares having the

     same rights, privileges and preferences as the Preferred Stock

     ("equivalent preferred shares")) or securities convertible into Preferred

     Stock or equivalent preferred shares at a price per share of Preferred

     Stock or equivalent preferred shares (or having a conversion price per

     share, if a security convertible into shares of Preferred Stock or

     equivalent preferred shares) less than the then current per share market

     price of the Preferred Stock (determined pursuant to Section 11(d) hereof)

     on such record date, the Purchase Price to be in effect after such record

     date shall be determined by multiplying the Purchase Price in effect

     immediately prior to such record date by a fraction, the numerator of

     which shall be the number of shares of Preferred Stock and equivalent

     preferred shares outstanding on such record date plus the number of shares

     of Preferred Stock and equivalent preferred shares which the aggregate

     offering price of the total number of shares of Preferred Stock and/or

     equivalent preferred shares so to be offered (and/or the aggregate initial

     conversion price of the convertible securities so to be offered) would

     purchase at such current market price, and the denominator of which shall

     be the number of shares of Preferred Stock and equivalent preferred shares

     outstanding on such record date plus the number of additional shares of

     Preferred Stock and/or equivalent preferred shares to be offered for

     subscription or purchase (or into which the convertible securities so to

     be offered are initially convertible); provided, however, that in no event

     shall the consideration to be paid upon the exercise of one Right be less
<PAGE>
     than the aggregate par value of the shares of capital stock of the Company

     issuable upon exercise of one Right.  In case such subscription price may

     be paid in a consideration part or all of which shall be in a form other

     than cash, the value of such consideration shall be as determined in good

     faith by the Board of Directors of the Company, whose determination shall

     be described in a statement filed with the Rights Agent.  Shares of

     Preferred Stock and equivalent preferred shares owned by or held for the

     account of the Company shall not be deemed outstanding for the purpose of

     any such computation.  Such adjustment shall be made successively whenever

     such a record date is fixed; and in the event that such rights, options or

     warrants are not so issued, the Purchase Price shall be adjusted to be the

     Purchase Price which would then be in effect if such record date had not

     been fixed.

          (c)  In case the Company shall fix a record date for the making of a

     distribution to all holders of the Preferred Stock (including any such

     distribution made in connection with a consolidation or merger in which

     the Company is the continuing or surviving corporation) of evidences of

     indebtedness or assets (other than a regular quarterly cash dividend or a

     dividend payable in Preferred Stock) or subscription rights or warrants

     (excluding those referred to in Section 11(b) hereof), the Purchase Price

     to be in effect after such record date shall be determined by multiplying

     the Purchase Price in effect immediately prior to such record date by a

     fraction, the numerator of which shall be the then current per share

     market price of the Preferred Stock (determined pursuant to Section 11(d)

     hereof) on such record date, less the fair market value (as determined in

     good faith by the Board of Directors of the Company whose determination

     shall be described in a statement filed with the Rights Agent) of the

     portion of the assets or evidences of indebtedness so to be distributed or

     of such subscription rights or warrants applicable to one share of
<PAGE>
     Preferred Stock, and the denominator of which shall be such current per

     share market price (determined pursuant to Section 11(d) hereof) of the

     Preferred Stock; provided, however, that in no event shall the

     consideration to be paid upon the exercise of one Right be less than the

     aggregate par value of the shares of capital stock of the Company to be

     issued upon exercise of one Right.  Such adjustments shall be made

     successively whenever such a record date is fixed; and in the event that

     such distribution is not so made, the Purchase Price shall again be

     adjusted to be the Purchase Price which would then be in effect if such

     record date had not been fixed.

          (d) (i)  Except as otherwise provided herein, for the purpose of any

     computation hereunder, the "current per share market price" of any

     security (a "Security" for the purpose of this Section 11(d)(i)) on any

     date shall be deemed to be the average of the daily closing prices per

     share of such Security for the 30 consecutive Trading Days (as such term

     is hereinafter defined) immediately prior to such date; provided, however,

     that in the event that the current per share market price of the Security

     is determined during a period following the announcement by the issuer of

     such Security of (A) a dividend or distribution on such Security payable

     in shares of such Security or securities convertible into such shares, or

     (B) any subdivision, combination or reclassification of such Security, and

     prior to the expiration of 30 Trading Days after the ex-dividend date for

     such dividend or distribution, or the record date for such subdivision,

     combination or reclassification, then, and in each such case, the current

     per share market price shall be appropriately adjusted to reflect the

     current market price per share equivalent of such Security.  The closing

     price for each day shall be the last sale price, regular way, or, in case

     no such sale takes place on such day, the average of the closing bid and

     asked prices, regular way, in either case as reported by the principal
<PAGE>
     consolidated transaction reporting system with respect to securities

     listed or admitted to trading on the New York Stock Exchange or, if the

     Security is not listed or admitted to trading on the New York Stock

     Exchange, as reported in the principal consolidated transaction reporting

     system with respect to securities listed on the principal national

     securities exchange on which the Security is listed or admitted to trading

     or, if the Security is not listed or admitted to trading on any national

     securities exchange, the last quoted price or, if not so quoted, the

     average of the high bid and low asked prices in the over-the-counter

     market, as reported by NASDAQ or such other system then in use, or, if on

     any such date the Security is not quoted by any such organization, the

     average of the closing bid and asked prices as furnished by a professional

     market maker making a market in the Security selected by the Board of

     Directors of the Company.  The term "Trading Day" shall mean a day on

     which the principal national securities exchange on which the Security is

     listed or admitted to trading is open for the transaction of business or,

     if the Security is not listed or admitted to trading on any national

     securities exchange, a Business Day.

          (ii)  For the purpose of any computation hereunder, if the Preferred

     Stock is publicly traded, the "current per share market price" of the

     Preferred Stock shall be determined in accordance with the method set

     forth in Section 11(d)(i).  If the Preferred Stock is not publicly traded

     but the Common Stock is publicly traded, the "current per share market

     price" of the Preferred Stock shall be conclusively deemed to be the cur-

     rent per share market price of the Common Stock as determined pursuant to

     Section 11(d)(i) multiplied by one thousand (appropriately adjusted to

     reflect any stock split, stock dividend or similar transaction occurring

     after the date hereof).  If neither the Common Stock nor the Preferred

     Stock is publicly traded, "current per share market price" shall mean the
<PAGE>
     fair value per share as determined in good faith by the Board of Directors

     of the Company, whose determination shall be described in a statement

     filed with the Rights Agent.

          (e)  No adjustment in the Purchase Price shall be required unless

     such adjustment would require an increase or decrease of at least 1% in

     the Purchase Price; provided, however, that any adjustments which by

     reason of this Section 11(e) are not required to be made shall be carried

     forward and taken into account in any subsequent adjustment.  All

     calculations under this Section 11 shall be made to the nearest cent or to

     the nearest one ten-thousandth of a share of Preferred Stock or share of

     Common Stock or other share or security as the case may be. 

     Notwithstanding the first sentence of this Section 11(e), any adjustment

     required by this Section 11 shall be made no later than the earlier of (i)

     three years from the date of the transaction which requires such

     adjustment or (ii) the date of the expiration of the right to exercise any

     Rights.

          (f)  If as a result of an adjustment made pursuant to Section 11(a)

     hereof, the holder of any Right thereafter exercised shall become entitled

     to receive any shares of capital stock of the Company other than the

     Preferred Stock, thereafter the Purchase Price and the number of such

     other shares so receivable upon exercise of a Right shall be subject to

     adjustment from time to time in a manner and on terms as nearly equivalent

     as practicable to the provisions with respect to the Preferred Stock

     contained in Sections 11(a), 11(b), 11(c), 11(e), 11(h), 11(i) and 11(m),

     and the provisions of Sections 7, 9, 10, 13 and 14 hereof with respect to

     the Preferred Stock shall apply on like terms to any such other shares.

          (g)  All Rights originally issued by the Company subsequent to any

     adjustment made to the Purchase Price hereunder shall evidence the right

     to purchase, at the adjusted Purchase Price, the number of one
<PAGE>
     one-thousandths of a share of Preferred Stock purchasable from time to

     time hereunder upon exercise of the Rights, all subject to further

     adjustment as provided herein.

          (h)  Unless the Company shall have exercised its election as provided

     in Section 11(i), upon each adjustment of the Purchase Price as a result

     of the calculations made in Sections 11(b) and (c), each Right outstanding

     immediately prior to the making of such adjustment shall thereafter evi-

     dence the right to purchase, at the adjusted Purchase Price, that number

     of one one-thousandths of a share of Preferred Stock (calculated to the

     nearest one ten-thousandth of a share of Preferred Stock) obtained by (i)

     multiplying (x) the number of one one-thousandths of a share covered by a

     Right immediately prior to such adjustment by (y) the Purchase Price in

     effect immediately prior to such adjustment of the Purchase Price and (ii)

     dividing the product so obtained by the Purchase Price in effect

     immediately after such adjustment of the Purchase Price.

          (i)  The Company may elect on or after the date of any adjustment of

     the Purchase Price to adjust the number of Rights, in substitution for any

     adjustment in the number of one one-thousandths of a share of Preferred

     Stock purchasable upon the exercise of a Right.  Each of the Rights

     outstanding after such adjustment of the number of Rights shall be

     exercisable for the number of one one-thousandths of a share of Preferred

     Stock for which a Right was exercisable immediately prior to such

     adjustment.  Each Right held of record prior to such adjustment of the

     number of Rights shall become that number of Rights (calculated to the

     nearest one ten-thousandth) obtained by dividing the Purchase Price in

     effect immediately prior to adjustment of the Purchase Price by the

     Purchase Price in effect immediately after adjustment of the Purchase

     Price.  The Company shall make a public announcement of its election to

     adjust the number of Rights, indicating the record date for the
<PAGE>
     adjustment, and, if known at the time, the amount of the adjustment to be

     made.  This record date may be the date on which the Purchase Price is

     adjusted or any day thereafter, but, if the Right Certificates have been

     issued, shall be at least 10 days later than the date of the public

     announcement.  If Right Certificates have been issued, upon each

     adjustment of the number of Rights pursuant to this Section 11(i), the

     Company may, as promptly as practicable, cause to be distributed to

     holders of record of Right Certificates on such record date Right

     Certificates evidencing, subject to Section 14 hereof, the additional

     Rights to which such holders shall be entitled as a result of such

     adjustment, or, at the option of the Company, shall cause to be

     distributed to such holders of record in substitution and replacement for

     the Right Certificates held by such holders prior to the date of

     adjustment, and upon surrender thereof, if required by the Company, new

     Right Certificates evidencing all the Rights to which such holders shall

     be entitled after such adjustment.  Right Certificates so to be

     distributed shall be issued, executed and countersigned in the manner

     provided for herein and shall be registered in the names of the holders of

     record of Right Certificates on the record date specified in the public

     announcement.

          (j)  Irrespective of any adjustment or change in the Purchase Price

     or the number of one one-thousandths of a share of Preferred Stock

     issuable upon the exercise of the Rights, the Right Certificates

     theretofore and thereafter issued may continue to express the Purchase

     Price and the number of one one-thousandths of a share of Preferred Stock

     which were expressed in the initial Right Certificates issued hereunder.

          (k)  Before taking any action that would cause an adjustment reducing

     the Purchase Price below the then par value, if any, of the Preferred

     Stock or other shares of capital stock issuable upon exercise of the
<PAGE>
     Rights, the Company shall take any corporate action which may, in the

     opinion of its counsel, be necessary in order that the Company may validly

     and legally issue fully paid and nonassessable shares of Preferred Stock

     or other such shares at such adjusted Purchase Price.

          (l)  In any case in which this Section 11 shall require that an

     adjustment in the Purchase Price be made effective as of a record date for

     a specified event, the Company may elect to defer until the occurrence of

     such event the issuing to the holder of any Right exercised after such

     record date of the Preferred Stock and other capital stock or securities

     of the Company, if any, issuable upon such exercise over and above the

     Preferred Stock and other capital stock or securities of the Company, if

     any, issuable upon such exercise on the basis of the Purchase Price in

     effect prior to such adjustment; provided, however, that the Company shall

     deliver to such holder a due bill or other appropriate instrument

     evidencing such holder's right to receive such additional shares upon the

     occurrence of the event requiring such adjustment.

          (m)  Anything in this Section 11 to the contrary notwithstanding, the

     Company shall be entitled to make such reductions in the Purchase Price,

     in addition to those adjustments expressly required by this Section 11, as

     and to the extent that it in its sole discretion shall determine to be

     advisable in order that any consolidation or subdivision of the Preferred

     Stock, issuance wholly for cash of any shares of Preferred Stock at less

     than the current market price, issuance wholly for cash or Preferred Stock

     or securities which by their terms are convertible into or exchangeable

     for Preferred Stock, dividends on Preferred Stock payable in shares of

     Preferred Stock or issuance of rights, options or warrants referred to

     hereinabove in Section 11(b), hereafter made by the Company to holders of

     its Preferred Stock shall not be taxable to such stockholders.
<PAGE>
          (n)  Anything in this Agreement to the contrary notwithstanding, in

     the event that at any time after the date of this Agreement and prior to

     the Distribution Date, the Company shall (i) declare or pay any dividend

     on the Common Stock payable in Common Stock or (ii) effect a subdivision,

     combination or consolidation of the Common Stock (by reclassification or

     otherwise than by payment of a dividend payable in Common Stock) into a

     greater or lesser number of Common Stock, then in any such case, the

     number of Rights associated with each share of Common Stock then

     outstanding, or issued or delivered thereafter, shall be proportionately

     adjusted so that the number of Rights thereafter associated with each

     share of Common Stock following any such event shall equal the result

     obtained by multiplying the number of Rights associated with each share of

     Common Stock immediately prior to such event by a fraction the numerator

     of which shall be the total number of shares of Common Stock outstanding

     immediately prior to the occurrence of the event and the denominator of

     which shall be the total number of shares of Common Stock outstanding

     immediately following the occurrence of such event.

          (o)  The Company agrees that, after the earlier of the Distribution

     Date or the Stock Acquisition Date, it will not, except as permitted by

     Sections 23, 24 or 27 hereof, take (or permit any Subsidiary to take) any

     action if at the time such action is taken it is reasonably foreseeable

     that such action will diminish substantially or eliminate the benefits

     intended to be afforded by the Rights.

          Section 12.  Certificate of Adjusted Purchase Price or Number of

Shares.  Whenever an adjustment is made as provided in Section 11 or 13 hereof,

the Company shall promptly (a) prepare a certificate setting forth such

adjustment, and a brief statement of the facts accounting for such adjustment,

(b) file with the Rights Agent and with each transfer agent for the Common

Stock or the Preferred Stock a copy of such certificate and (c) mail a brief
<PAGE>
summary thereof to each holder of a Right Certificate in accordance with Sec-

tion 25 hereof (if so required under Section 25 hereof).  The Rights Agent

shall be fully protected in relying on any such certificate and on any

adjustment therein contained and shall not be deemed to have knowledge of any

such adjustment unless and until it shall have received such certificate.

          Section 13.  Consolidation, Merger or Sale or Transfer of Assets or

Earnings Power.  (a)  In the event, directly or indirectly, at any time after

any Person has become an Acquiring Person, (i) the Company shall merge with and

into any other Person, (ii) any Person shall consolidate with the Company, or

any Person shall merge with and into the Company and the Company shall be the

continuing or surviving corporation of such merger and, in connection with such

merger, all or part of the Common Stock shall be changed into or exchanged for

stock or other securities of any other Person (or of the Company) or cash or

any other property, or (iii) the Company shall sell or otherwise transfer (or

one or more of its Subsidiaries shall sell or otherwise transfer), in one or

more transactions, assets or earning power aggregating 50% or more of the

assets or earning power of the Company and its Subsidiaries (taken as a whole)

to any other Person (other than the Company or one or more of its wholly-owned

Subsidiaries), then upon the first occurrence of such event, proper provision

shall be made so that: (A) each holder of record of a Right (other than Rights

which have become void pursuant to Section 11(a)(ii)) shall thereafter have the

right to receive, upon the exercise thereof at a price equal to the then

current Purchase Price multiplied by the number of one one-thousandths of a

share of Preferred Stock for which a Right was exercisable (whether or not such

Right was then exercisable) immediately prior to the time that any Person first

became an Acquiring Person (each as subsequently adjusted thereafter pursuant

to Sections 11(a)(i), 11(b), 11(c), 11(h), 11(i) and 11(m)), in accordance with

the terms of this Agreement and in lieu of Preferred Stock, such number of

validly issued, fully paid and non-assessable and freely tradeable shares of
<PAGE>
Common Stock of the Principal Party (as defined herein) not subject to any

liens, encumbrances, rights of first refusal or other adverse claims, as shall

be equal to the result obtained by (1) multiplying the then current Purchase

Price by the number of one one-thousandths of a share of Preferred Stock for

which a Right was exercisable immediately prior to the time that any Person

first became an Acquiring Person (as subsequently adjusted thereafter pursuant

to Sections 11(a)(i), 11(b), 11(c), 11(h), 11(i) and 11(m)) and (2) dividing

that product by 50% of the then current per share market price of the Common

Stock of such Principal Party (determined pursuant to Section 11(d)(i) hereof)

on the date of consummation of such consolidation, merger, sale or transfer;

provided that the Purchase Price and the number of shares of Common Stock of

such Principal Party issuable upon exercise of each Right shall be further

adjusted as provided in Section 11(f) of this Agreement to reflect any events

occurring in respect of such Principal Party after the date of the such

consolidation, merger, sale or transfer; (B) such Principal Party shall

thereafter be liable for, and shall assume, by virtue of such consolidation,

merger, sale or transfer, all the obligations and duties of the Company

pursuant to this Agreement; (C) the term "Company" shall thereafter be deemed

to refer to such Principal Party; and (D) such Principal Party shall take such

steps (including, but not limited to, the reservation of a sufficient number of

its shares of Common Stock in accordance with Section 9 hereof) in connection

with such consummation of any such transaction as may be necessary to assure

that the provisions hereof shall thereafter be applicable, as nearly as

reasonably may be, in relation to the shares of its Common Stock thereafter

deliverable upon the exercise of the Rights; provided that, upon the subsequent

occurrence of any consolidation, merger, sale or transfer of assets or other

extraordinary transaction in respect of such Principal Party, each holder of a

Right shall thereupon be entitled to receive, upon exercise of a Right and

payment of the Purchase Price as provided in this Section 13(a), such cash,
<PAGE>
shares, rights, warrants and other property which such holder would have been

entitled to receive had such holder, at the time of such transaction, owned the

Common Stock of the Principal Party receivable upon the exercise of a Right

pursuant to this Section 13(a), and such Principal Party shall take such steps

(including, but not limited to, reservation of shares of stock) as may be

necessary to permit the subsequent exercise of the Rights in accordance with

the terms hereof for such cash, shares, rights, warrants and other property.

          (b)  "Principal Party" shall mean

               (i)  in the case of any transaction described in (i) or (ii) of

     the first sentence of Section 13(a) hereof:  (A) the Person that is the

     issuer of the securities into which the shares of Common Stock are

     converted in such merger or consolidation, or, if there is more than one

     such issuer, the issuer the shares of Common Stock of which have the

     greatest aggregate market value of shares outstanding, or (B) if no

     securities are so issued, (x) the Person that is the other party to the

     merger, if such Person survives said merger, or, if there is more than one

     such Person, the Person the shares of Common Stock of which have the

     greatest aggregate market value of shares outstanding or (y) if the Person

     that is the other party to the merger does not survive the merger, the

     Person that does survive the merger (including the Company if it survives)

     or (z) the Person resulting from the consolidation; and

               (ii) in the case of any transaction described in (iii) of the

     first sentence in Section 13(a) hereof, the Person that is the party

     receiving the greatest portion of the assets or earning power transferred

     pursuant to such transaction or transactions, or, if each Person that is a

     party to such transaction or transactions receives the same portion of the

     assets or earning power so transferred or if the Person receiving the

     greatest portion of the assets or earning power cannot be determined,
<PAGE>
     whichever of such Persons as is the issuer of Common Stock having the

     greatest aggregate market value of shares outstanding;

provided, however, that in any such case described in the foregoing clause

(b)(i) or (b)(ii), if the Common Stock of such Person is not at such time or

has not been continuously over the preceding 12-month period registered under

Section 12 of the Exchange Act, then (1) if such Person is a direct or indirect

Subsidiary of another Person the Common Stock of which is and has been so

registered, the term "Principal Party" shall refer to such other Person, or (2)

if such Person is a Subsidiary, directly or indirectly, of more than one

Person, the Common Stock of all of which is and has been so registered, the

term "Principal Party" shall refer to whichever of such Persons is the issuer

of Common Stock having the greatest aggregate market value of shares

outstanding, or (3) if such Person is owned, directly or indirectly, by a joint

venture formed by two or more Persons that are not owned, directly or

indirectly, by the same Person, the rules set forth in clauses (1) and (2)

above shall apply to each of the owners having an interest in the venture as if

the Person owned by the joint venture was a Subsidiary of both or all of such

joint venturers, and the Principal Party in each such case shall bear the

obligations set forth in this Section 13 in the same ratio as its interest in

such Person bears to the total of such interests.

          (c)  The Company shall not consummate any consolidation, merger, sale

or transfer referred to in Section 13(a) hereof unless prior thereto the

Company and the Principal Party involved therein shall have executed and

delivered to the Rights Agent an agreement confirming that the requirements of

Sections 13(a) and (b) hereof shall promptly be performed in accordance with

their terms and that such consolidation, merger, sale or transfer of assets

shall not result in a default by the Principal Party under this Agreement as

the same shall have been assumed by the Principal Party pursuant to Sections
<PAGE>
13(a) and (b) hereof and providing that, as soon as practicable after executing

such agreement pursuant to this Section 13, the Principal Party will:

               (i)  prepare and file a registration statement under the

     Securities Act, if necessary, with respect to the Rights and the

     securities purchasable upon exercise of the Rights on an appropriate form,

     use its best efforts to cause such registration statement to become

     effective as soon as practicable after such filing and use its best

     efforts to cause such registration statement to remain effective (with a

     prospectus at all times meeting the requirements of the Securities Act)

     until the Final Expiration Date, and similarly comply with applicable

     state securities laws;

               (ii) use its best efforts, if the Common Stock of the Principal

     Party shall be listed or admitted to trading on the New York Stock

     Exchange or on a national securities exchange, to list or admit to trading

     (or continue the listing of) the Rights and the securities purchasable

     upon exercise of the Rights on the New York Stock Exchange or such

     securities exchange, or, if the Common Stock of the Principal Party shall

     not be listed or admitted to trading on the New York Stock Exchange or a

     national securities exchange, to cause the Rights and the securities

     receivable upon exercise of the Rights to be reported by such other system

     then in use;

               (iii)  deliver to holders of the Rights historical financial

     statements for the Principal Party which comply in all respects with the

     requirements for registration on Form 10 (or any successor form) under the

     Exchange Act; and

               (iv)  obtain waivers of any rights of first refusal or

     preemptive rights in respect of the Common Stock of the Principal Party

     subject to purchase upon exercise of outstanding Rights.
<PAGE>
          (d)  In case the Principal Party has provision in any of its

authorized securities or in its certificate of incorporation or by-laws or

other instrument governing its corporate affairs, which provision would have

the effect of (i) causing such Principal Party to issue (other than to holders

of Rights pursuant to this Section 13), in connection with, or as a consequence

of, the consummation of a transaction referred to in this Section 13, shares of

Common Stock of such Principal Party at less than the then current market price

per share thereof (determined pursuant to Section 11(d) hereof) or securities

exercisable for, or convertible into, Common Stock of such Principal Party at

less than such then current market price, or (ii) providing for any special

payment, tax or similar provision in connection with the issuance of the Common

Stock of such Principal Party pursuant to the provisions of Section 13, then,

in such event, the Company hereby agrees with each holder of Rights that it

shall not consummate any such transaction unless prior thereto the Company and

such Principal Party shall have executed and delivered to the Rights Agent a

supplemental agreement providing that the provision in question of such

Principal Party shall have been cancelled, waived or amended, or that the

authorized securities shall be redeemed, so that the applicable provision will

have no effect in connection with, or as a consequence of, the consummation of

the proposed transaction.

          (e)  The Company covenants and agrees that it shall not, at any time

after a Person first becomes an Acquiring Person, enter into any transaction of

the type contemplated by (i) - (iii) of Section 13(a) hereof if (x) at the time

of or immediately after such consolidation, merger, sale, transfer or other

transaction there are any rights, warrants or other instruments or securities

outstanding or agreements in effect which would substantially diminish or

otherwise eliminate the benefits intended to be afforded by the Rights, (y)

prior to, simultaneously with or immediately after such consolidation, merger,

sale, transfer of other transaction, the stockholders of the Person who
<PAGE>
constitutes, or would constitute, the Principal Party for purposes of Section

13(a) hereof shall have received a distribution of Rights previously owned by

such Person or any of its Affiliates or Associates or (z) the form or nature of

organization of the Principal Party would preclude or limit the exercisability

of the Rights.

          Section 14.  Fractional Rights and Fractional Shares.  (a)  The

Company shall not be required to issue fractions of Rights or to distribute

Right Certificates which evidence fractional Rights.  In lieu of such

fractional Rights, there shall be paid to the registered holders of the Right

Certificates with regard to which such fractional Rights would otherwise be

issuable, an amount in cash equal to the same fraction of the current market

value of a whole Right.  For the purposes of this Section 14(a), the current

market value of a whole Right shall be the closing price of the Rights for the

Trading Day immediately prior to the date on which such fractional Rights would

have been otherwise issuable.  The closing price for any day shall be the last

sale price, regular way, or, in case no such sale takes place on such day, the

average of the closing bid and asked prices, regular way, in either case as

reported in the principal consolidated transaction reporting system with

respect to securities listed or admitted to trading on the New York Stock

Exchange or, if the Rights are not listed or admitted to trading on the New

York Stock Exchange, as reported in the principal consolidated transaction

reporting system with respect to securities listed on the principal national

securities exchange on which the Rights are listed or admitted to trading or,

if the Rights are not listed or admitted to trading on any national securities

exchange, the last quoted price or, if not so quoted, the average of the high

bid and low asked prices in the over-the-counter market, as reported by NASDAQ

or such other system then in use or, if on any such date the Rights are not

quoted by any such organization, the average of the closing bid and asked

prices as furnished by a professional market maker making a market in the
<PAGE>
Rights selected by the Board of Directors of the Company.  If on any such date

no such market maker is making a market in the Rights, the fair value of the

Rights on such date as determined in good faith by the Board of Directors of

the Company shall be used.

          (b)  The Company shall not be required to issue fractions of

Preferred Stock (other than fractions which are integral multiples of one

one-thousandth of a share of Preferred Stock) upon exercise of the Rights or to

distribute certificates which evidence fractional shares of Preferred Stock

(other than fractions which are integral multiples of one one-thousandth of a

share of Preferred Stock).  Interests in fractions of Preferred Stock in

integral multiples of one one-thousandth of a share of Preferred Stock may, at

the election of the Company, be evidenced by depositary receipts, pursuant to

an appropriate agreement between the Company and a depositary selected by it;

provided, that such agreement shall provide that the holders of such depositary

receipts shall have all the rights, privileges and preferences to which they

are entitled as beneficial owners of the Preferred Stock represented by such

depositary receipts.  In lieu of fractional shares of Preferred Stock that are

not integral multiples of one one-thousandth of a share of Preferred Stock, the

Company shall pay to the registered holders of Right Certificates at the time

such Rights are exercised as herein provided an amount in cash equal to the

same fraction of the current market value of one share of Preferred Stock.  For

the purposes of this Section 14(b), the current market value of a share of

Preferred Stock shall be the closing price of a share of Preferred Stock (as

determined pursuant to Section 11(d)(i) hereof) for the Trading Day immediately

prior to the date of such exercise.

          (c)  The holder of a Right by the acceptance of the Right expressly

waives his right to receive any fractional Rights or any fractional shares upon

exercise of a Right (except as provided above).
<PAGE>
          Section 15.  Rights of Action.  All rights of action in respect of

this Agreement, excepting the rights of action given to the Rights Agent under

Section 18 hereof, are vested in the respective registered holders of the Right

Certificates (and, prior to the Distribution Date, the registered holders of

the Common Stock); and any registered holder of any Right Certificate (or,

prior to the Distribution Date, of the Common Stock), without the consent of

the Rights Agent or of the holder of any other Right Certificate (or, prior to

the Distribution Date, of the Common Stock), on his own behalf and for his own

benefit, may enforce, and may institute and maintain any suit, action or

proceeding against the Company to enforce, or otherwise act in respect of, his

right to exercise the Rights evidenced by such Right Certificate (or, prior to

the Distribution Date, such Common Stock) in the manner provided in such Right

Certificate and in this Agreement.  Without limiting the foregoing or any

remedies available to the holders of Rights, it is specifically acknowledged

that the holders of Rights would not have an adequate remedy at law for any

breach of this Agreement and will be entitled to specific performance of the

obligations under, and injunctive relief against actual or threatened

violations of, the obligations of any Person subject to this Agreement.

          Section 16.  Agreement of Right Holders.  Every holder of a Right, by

accepting the same, consents and agrees with the Company and the Rights Agent

and with every other holder of a Right that:

          (a)  prior to the Distribution Date, the Rights will be transferable

     only in connection with the transfer of the Common Stock;

          (b)  after the Distribution Date, the Right Certificates are

     transferable only on the registry books of the Rights Agent if surrendered

     at the office or agency of the Rights Agent designated for such purpose,

     duly endorsed or accompanied by a proper instrument of transfer; and

          (c)  the Company and the Rights Agent may deem and treat the Person

     in whose name the Right Certificate (or, prior to the Distribution Date,
<PAGE>
     the Common Stock certificate) is registered as the absolute owner thereof

     and of the Rights evidenced thereby (notwithstanding any notations of

     ownership or writing on the Right Certificates or the Common Stock

     certificate made by anyone other than the Company or the Rights Agent) for

     all purposes whatsoever, and neither the Company nor the Rights Agent

     shall be affected by any notice to the contrary.

          Section 17.  Right Certificate Holder Not Deemed a Stockholder.  No

holder, as such, of any Right Certificate shall be entitled to vote, receive

dividends or be deemed for any purpose the holder of the Preferred Stock or any

other securities of the Company which may at any time be issuable on the

exercise of the Rights represented thereby, nor shall anything contained herein

or in any Right Certificate be construed to confer upon the holder of any Right

Certificate, as such, any of the rights of a stockholder of the Company or any

right to vote for the election of directors or upon any matter submitted to

stockholders at any meeting thereof, or to give or withhold consent to any

corporate action, or to receive notice of meetings or other actions affecting

stockholders (except as provided in this Agreement), or to receive dividends or

subscription rights, or otherwise, until the Rights evidenced by such Right

Certificate shall have been exercised in accordance with the provisions hereof.

          Section 18.  Concerning the Rights Agent.  (a)  The Company agrees to

pay to the Rights Agent reasonable compensation for all services rendered by it

hereunder and, from time to time, on demand of the Rights Agent, its reasonable

expenses and counsel fees and other disbursements incurred in the

administration and execution of this Agreement and the exercise and performance

of its duties hereunder.  The Company also agrees to indemnify the Rights Agent

for, and to hold it harmless against, any loss, liability or expense, incurred

without negligence, bad faith or willful misconduct on the part of the Rights

Agent, for anything done or omitted by the Rights Agent in connection with the

acceptance and administration of this Agreement, including the costs and
<PAGE>
expenses of defending against any claim of liability arising therefrom,

directly or indirectly.

          (b)  The Rights Agent shall be protected and shall incur no liability

for, or in respect of any action taken, suffered or omitted by it in connection

with, its administration of this Agreement in reliance upon any Right

Certificate or certificate for the Preferred Stock or Common Stock or for other

securities of the Company, instrument of assignment or transfer, power of

attorney, endorsement, affidavit, letter, notice, direction, consent,

certificate, statement, or other paper or document believed by it to be genuine

and to be signed, executed and, where necessary, verified or acknowledged, by

the proper Person or Persons, or otherwise upon the advice of counsel as set

forth in Section 20 hereof.

          Section 19.  Merger or Consolidation or Change of Name of Rights

Agent.  (a)  Any corporation into which the Rights Agent or any successor

Rights Agent may be merged or with which it may be consolidated, or any

corporation resulting from any merger or consolidation to which the Rights

Agent or any successor Rights Agent shall be a party, or any corporation

succeeding to the stock transfer or corporate trust powers of the Rights Agent

or any successor Rights Agent, shall be the successor to the Rights Agent under

this Agreement without the execution or filing of any paper or any further act

on the part of any of the parties hereto; provided, that such corporation would

be eligible for appointment as a successor Rights Agent under the provisions of

Section 21 hereof.  In case at the time such successor Rights Agent shall

succeed to the agency created by this Agreement, any of the Right Certificates

shall have been countersigned but not delivered, any such successor Rights

Agent may adopt the countersignature of the predecessor Rights Agent and de-

liver such Right Certificates so countersigned; and in case at that time any of

the Right Certificates shall not have been countersigned, any successor Rights

Agent may countersign such Right Certificates either in the name of the prede-
<PAGE>
cessor Rights Agent or in the name of the successor Rights Agent; and in all

such cases such Right Certificates shall have the full force provided in the

Right Certificates and in this Agreement. 

          (b)  In case at any time the name of the Rights Agent shall be

changed and at such time any of the Right Certificates shall have been

countersigned but not delivered the Rights Agent may adopt the countersignature

under its prior name and deliver Right Certificates so countersigned; and in

case at that time any of the Right Certificates shall not have been

countersigned, the Rights Agent may countersign such Right Certificates either

in its prior name or in its changed name and in all such cases such Right

Certificates shall have the full force provided in the Right Certificates and

in this Agreement.

          Section 20.  Duties of Rights Agent.  The Rights Agent undertakes the

duties and obligations imposed by this Agreement upon the following terms and

conditions, by all of which the Company and the holders of Right Certificates,

by their acceptance thereof, shall be bound:

          (a)  The Rights Agent may consult with legal counsel (who may be

     legal counsel for the Company), and the opinion of such counsel shall be

     full and complete authorization and protection to the Rights Agent as to

     any action taken or omitted by it in good faith and in accordance with

     such opinion.

          (b)  Whenever in the performance of its duties under this Agreement

     the Rights Agent shall deem it necessary or desirable that any fact or

     matter be proved or established by the Company prior to taking or

     suffering any action hereunder, such fact or matter (unless other evidence

     in respect thereof be herein specifically prescribed) may be deemed to be

     conclusively proved and established by a certificate signed by any one of

     the Chairman of the Board of Directors, the President, any Vice President,

     the Treasurer, the Controller or the Secretary of the Company and
<PAGE>
     delivered to the Rights Agent; and such certificate shall be full

     authorization to the Rights Agent for any action taken or suffered in good

     faith by it under the provisions of this Agreement in reliance upon such

     certificate.

          (c)  The Rights Agent shall be liable hereunder to the Company and

     any other Person only for its own negligence, bad faith or wilful

     misconduct.

          (d)  The Rights Agent shall not be liable for or by reason of any of

     the statements of fact or recitals contained in this Agreement or in the

     Right Certificates (except its countersignature thereof) or be required to

     verify the same, but all such statements and recitals are and shall be

     deemed to have been made by the Company only.

          (e)  The Rights Agent shall not be under any responsibility in

     respect of the validity of this Agreement or the execution and delivery

     hereof (except the due execution hereof by the Rights Agent) or in respect

     of the validity or execution of any Right Certificate (except its

     countersignature thereof); nor shall it be responsible for any breach by

     the Company of any covenant or condition contained in this Agreement or in

     any Right Certificate; nor shall it be responsible for any change in the

     exercisability of the Rights (including the Rights becoming void pursuant

     to Section 11(a)(ii) hereof) or any adjustment in the terms of the Rights

     (including the manner, method or amount thereof) provided for in Sections

     3, 11, 13, 23 and 24, or the ascertaining of the existence of facts that

     would require any such change or adjustment (except with respect to the

     exercise of Rights evidenced by Right Certificates after receipt of a

     certificate furnished pursuant to Section 12, describing such change or

     adjustment); nor shall it by any act hereunder be deemed to make any

     representation or warranty as to the authorization or reservation of any

     shares of Preferred Stock or other securities to be issued pursuant to
<PAGE>
     this Agreement or any Right Certificate or as to whether any shares of

     Preferred Stock or other securities will, when issued, be validly

     authorized and issued, fully paid and nonassessable.

          (f)  The Company agrees that it will perform, execute, acknowledge

     and deliver or cause to be performed, executed, acknowledged and delivered

     all such further and other acts, instruments and assurances as may

     reasonably be required by the Rights Agent for the carrying out or

     performing by the Rights Agent of the provisions of this Agreement.

          (g)  The Rights Agent is hereby authorized and directed to accept

     instructions with respect to the performance of its duties hereunder from

     any person reasonably believed by the Rights Agent to be one of the

     Chairman of the Board of Directors, the President, the Chief Financial

     Officer or the Secretary of the Company, and to apply to such officers for

     advice or instructions in connection with its duties, and it shall not be

     liable for any action taken or suffered by it in good faith in accordance

     with instructions of any such officer or for any delay in acting while

     waiting for those instructions.  Any application by the Rights Agent for

     written instructions from the Company may, at the option of the Rights

     Agent, set forth in writing any action proposed to be taken or omitted by

     the Rights Agent under this Agreement and the date on and/or after which

     such action shall be taken or such omission shall be effective.  The

     Rights Agent shall not be liable for any action taken by, or omission of,

     the Rights Agent in accordance with a proposal included in any such

     application on or after the date specified in such application (which date

     shall not be less than five Business Days after the date any officer of

     the Company actually receives such application, unless any such officer

     shall have consented in writing to an earlier date) unless, prior to

     taking any such action (or the effective date in the case of an omission),
<PAGE>
     the Rights Agent shall have received written instructions in response to

     such application specifying the action to be taken or omitted. 

          (h)  The Rights Agent and any stockholder, director, officer or

     employee of the Rights Agent may buy, sell or deal in any of the Rights or

     other securities of the Company or become pecuniarily interested in any

     transaction in which the Company may be interested, or contract with or

     lend money to the Company or otherwise act as fully and freely as though

     it were not Rights Agent under this Agreement.  Nothing herein shall

     preclude the Rights Agent from acting in any other capacity for the

     Company or for any other legal entity.

          (i)  The Rights Agent may execute and exercise any of the rights or

     powers hereby vested in it or perform any duty hereunder either itself or

     by or through its attorneys or agents, and the Rights Agent shall not be

     answerable or accountable for any act, default, neglect or misconduct of

     any such attorneys or agents or for any loss to the Company resulting from

     any such act, default, neglect or misconduct, provided reasonable care was

     exercised in the selection and continued employment thereof.

          (j)  If, with respect to any Rights Certificate surrendered to the

     Rights Agent for exercise or transfer, the certificate contained in the

     form of assignment or the form of election to purchase set forth on the

     reverse thereof, as the case may be, has not been completed to certify the

     holder is not an Acquiring Person (or an Affiliate or Associate thereof),

     a Rights Agent shall not take any further action with respect to such

     requested exercise or transfer without first consulting with the Company.

          Section 21.  Change of Rights Agent.  The Rights Agent or any

successor Rights Agent may resign and be discharged from its duties under this

Agreement upon 30 days' notice in writing mailed to the Company and to each

transfer agent of the Common Stock or Preferred Stock by registered or

certified mail, and, following the Distribution Date, to the holders of the
<PAGE>
Right Certificates by first-class mail.  The Company may remove the Rights

Agent or any successor Rights Agent upon 30 days' notice in writing, mailed to

the Rights Agent or successor Rights Agent, as the case may be, and to each

transfer agent of the Common Stock or Preferred Stock by registered or

certified mail, and, following the Distribution Date, to the holders of the

Right Certificates by first-class mail.  If the Rights Agent shall resign or be

removed or shall otherwise become incapable of acting, the Company shall

appoint a successor to the Rights Agent.  If the Company shall fail to make

such appointment within a period of 30 days after giving notice of such removal

or after it has been notified in writing of such resignation or incapacity by

the resigning or incapacitated Rights Agent or by the holder of a Right

Certificate (who shall, with such notice, submit his Right Certificate for

inspection by the Company), then the registered holder of any Right Certificate

may apply to any court of competent jurisdiction for the appointment of a new

Rights Agent.  Any successor Rights Agent, whether appointed by the Company or

by such a court, shall be a corporation organized and doing business under the

laws of the United States or any State thereof, which is authorized under such

laws to exercise corporate trust or stock transfer powers and is subject to

supervision or examination by federal or state authority and which has at the

time of its appointment as Rights Agent a combined capital and surplus of at

least $50 million.  After appointment, the successor Rights Agent shall be

vested with the same powers, rights, duties and responsibilities as if it had

been originally named as Rights Agent without further act or deed; but the

predecessor Rights Agent shall deliver and transfer to the successor Rights

Agent any property at the time held by it hereunder, and execute and deliver

any further assurance, conveyance, act or deed necessary for the purpose.  Not

later than the effective date of any such appointment the Company shall file

notice thereof in writing with the predecessor Rights Agent and each transfer

agent of the Common Stock or Preferred Stock, and, following the Distribution
<PAGE>
Date, mail a notice thereof in writing to the registered holders of the Right

Certificates.  Failure to give any notice provided for in this Section 21,

however, or any defect therein, shall not affect the legality or validity of

the resignation or removal of the Rights Agent or the appointment of the

successor Rights Agent, as the case may be.

          Section 22.  Issuance of New Right Certificates.  Notwithstanding any

of the provisions of this Agreement or of the Rights to the contrary, the

Company may, at its option, issue new Right Certificates evidencing Rights in

such forms as may be approved by its Board of Directors to reflect any

adjustment or change in the Purchase Price and the number or kind or class of

shares or other securities or property purchasable under the Right Certificates

made in accordance with the provisions of this Agreement.  In addition, in

connection with the issuance or sale of Common Stock following the Distribution

Date and prior to the earlier of the Redemption Date and the Final Expiration

Date, the Company may with respect to shares of Common Stock so issued or sold

pursuant to (i) the exercise of stock options, (ii) under any employee plan or

arrangement, (iii) upon the exercise, conversion or exchange of securities

notes or debentures issued by the Company or (iv) a contractual obligation of

the Company in each case existing prior to the Distribution Date, issue Rights

Certificates representing the appropriate number of Rights in connection with

such issuance or sale.

          Section 23.  Redemption.  (a) The Board of Directors of the Company

may, at any time prior to such time as any Person first becomes an Acquiring

Person, redeem all but not less than all the then outstanding Rights at a

redemption price of $.01 per Right, appropriately adjusted to reflect any stock

split, stock dividend or similar transaction occurring after the date hereof

(the redemption price being hereinafter referred to as the "Redemption Price"). 

The redemption of the Rights may be made effective at such time, on such basis
<PAGE>
and with such conditions as the Board of Directors in its sole discretion may

establish.

          (b)  Immediately upon the action of the Board of Directors ordering

the redemption of the Rights pursuant to paragraph (a) of this Section 23 (or

at such later time as the Board of Directors may establish for the

effectiveness of such redemption), and without any further action and without

any notice, the right to exercise the Rights will terminate and the only right

thereafter of the holders of Rights shall be to receive the Redemption Price. 

The Company shall promptly give public notice of any such redemption; provided,

however, that the failure to give, or any defect in, any such notice shall not

affect the validity of such redemption.   Within 10 days after such action of

the Board of Directors ordering the redemption of the Rights (or such later

time as the Board of Directors may establish for the effectiveness of such

redemption), the Company shall mail a notice of redemption to all the holders

of the then outstanding Rights at their last addresses as they appear upon the

registry books of the Rights Agent or, prior to the Distribution Date, on the

registry books of the transfer agent for the Common Stock.  Any notice which is

mailed in the manner herein provided shall be deemed given, whether or not the

holder receives the notice.  Each such notice of redemption shall state the

method by which the payment of the Redemption Price will be made.  

          Section 24.  Exchange.  (a)  The Board of Directors

of the Company may, at its option, at any time after any Person first becomes

an Acquiring Person, exchange all or part of the then outstanding and

exercisable Rights (which shall not include Rights that have become void

pursuant to the provisions of Section 11(a)(ii) hereof) for shares of Common

Stock at an exchange ratio of one share of Common Stock per Right, (such

exchange ratio being hereinafter referred to as the "Exchange Ratio"). 

Notwithstanding the foregoing, the Board of Directors shall not be empowered to

effect such exchange at any time after (1) any Person (other than an Exempt
<PAGE>
Person), together with all Affiliates and Associates of such Person, becomes

the Beneficial Owner of shares of Common Stock aggregating 50% or more of the

shares of Common Stock then outstanding or (2) the occurrence of an event

specified in Section 13(a) hereof.

          (b)  Immediately upon the action of the Board of Directors of the

Company ordering the exchange of any Rights pursuant to paragraph (a) of this

Section 24 and without any further action and without any notice, the right to

exercise such Rights shall terminate and the only right thereafter of a holder

of such Rights shall be to receive that number of shares of Common Stock equal

to the number of such Rights held by such holder multiplied by the Exchange

Ratio.  The Company shall promptly give public notice of any such exchange;

provided, however, that the failure to give, or any defect in, such notice

shall not affect the validity of such exchange.  The Company shall promptly

mail a notice of any such exchange to all of the holders of the Rights so

exchanged at their last addresses as they appear upon the registry books of the

Rights Agent.  Any notice which is mailed in the manner herein provided shall

be deemed given, whether or not the holder receives the notice.  Each such

notice of exchange will state the method by which the exchange of the shares of

Common Stock for Rights will be effected and, in the event of any partial

exchange, the number of Rights which will be exchanged.  Any partial exchange

shall be effected pro rata based on the number of Rights (other than Rights

which have become void pursuant to the provisions of Section 11(a)(ii) hereof)

held by each holder of Rights.

          (c)  In the event that there shall not be sufficient shares of Common

Stock issued but not outstanding or authorized but unissued to permit any

exchange of Rights as contemplated in accordance with this Section 24, the

Company may, in its discretion, take such action as may be necessary to

authorize additional shares of Common Stock for issuance upon exchange of the

Rights.  In the event that the Company shall determine not to take such action
<PAGE>
or shall, after good faith effort, be unable to take such action as may be

necessary to authorize such additional shares of Common Stock, the Company

shall substitute, to the extent of such insufficiency, for each share of Common

Stock that would otherwise be issuable upon exchange of a Right, a number of

shares of Preferred Stock or fractions thereof (or equivalent preferred shares

as such term is defined in Section 11(b)) having an aggregate current per share

market price (determined pursuant to Section 11(d) hereof) equal to the current

per share market price of one share of Common Stock (determined pursuant to

Section 11(d) hereof) as of the date of issuance of such shares of Preferred

Stock or fractions thereof (or equivalent preferred shares).

          (d)  The Company shall not, in connection with any exchange pursuant

to this Section 24, be required to issue fractions of shares of Common Stock or

to distribute certificates which evidence fractional shares of Common Stock. 

In lieu of such fractional shares of Common Stock, the Company shall pay to the

registered holders of the Right Certificates with regard to which such

fractional shares of Common Stock would otherwise be issuable an amount in cash

equal to the same fraction of the current market value of a whole share of

Common Stock.  For the purposes of this paragraph (d), the current market value

of a whole share of Common Stock shall be the closing price of a share of

Common Stock (as determined pursuant to the second sentence of Section 11(d)(i)

hereof) for the Trading Day immediately prior to the date of exchange pursuant

to this Section 24.

          Section 25.  Notice of Certain Events.  (a) In case the Company shall

at any time after the earlier of the Distribution Date or the Stock Acquisition

Date propose (i) to pay any dividend payable in stock of any class to the

holders of its Preferred Stock or to make any other distribution to the holders

of its Preferred Stock (other than a regular quarterly cash dividend), (ii) to

offer to the holders of its Preferred Stock rights or warrants to subscribe for

or to purchase any additional shares of Preferred Stock or shares of stock of
<PAGE>
any class or any other securities, rights or options, (iii) to effect any

reclassification of its Preferred Stock (other than a reclassification

involving only the subdivision of outstanding Preferred Stock), (iv) to effect

the liquidation, dissolution or winding up of the Company, or (v) to declare or

pay any dividend on the Common Stock payable in Common Stock or to effect a

subdivision, combination or consolidation of the Common Stock (by reclas-

sification or otherwise than by payment of dividends in Common Stock), then, in

each such case, the Company shall give to each holder of a Right Certificate,

in accordance with Section 26 hereof, a notice of such proposed action, which

shall specify the record date for the purposes of such stock dividend, or

distribution of rights or warrants, or the date on which such liquidation,

dissolution or winding up is to take place and the date of participation

therein by the holders of the Common Stock and/or Preferred Stock, if any such

date is to be fixed, and such notice shall be so given in the case of any

action covered by clause (i) or (ii) above at least 10 days prior to the record

date for determining holders of the Preferred Stock for purposes of such

action, and in the case of any such other action, at least 10 days prior to the

date of the taking of such proposed action or the date of participation therein

by the holders of the Common Stock and/or Preferred Stock, whichever shall be

the earlier.

          (b)  In case any event described in Section 11(a)(ii) or Section 13

shall occur then the Company shall as soon as practicable thereafter give to

each holder of a Right Certificate (or if occurring prior to the Distribution

Date, the holders of the Common Stock) in accordance with Section 26 hereof, a

notice of the occurrence of such event, which notice shall describe such event

and the consequences of such event to holders of Rights under Section 11(a)(ii)

and Section 13 hereof.

Price.   Upon the delivery of a certificate from an appropriate officer of the

Company which states that the proposed supplement or amendment is in compliance

                          CADENCE DESIGN SYSTEMS, INC.

                         (Pursuant to Section 151 of the
                General Corporation Law of the State of Delaware)

                               ___________________



                 Cadence Design Systems, Inc., a corporation organized and
existing under the General Corporation Law of the State of Delaware
(hereinafter called the "Company"), hereby certifies that the following
resolution was duly adopted by the Board of Directors of the Company as
required by Section 151 of the General Corporation Law of the State of Delaware
at a meeting duly called and held on February 9, 1996:

                 RESOLVED, that pursuant to the authority granted to and vested
in the Board of Directors of the Company (hereinafter called the "Board of
Directors" or the "Board") in accordance with the provisions of the Company's
Certificate of Incorporation, (hereinafter called the "Certificate of
Incorporation"), the Board of Directors on May 26, 1989 adopted a resolution
creating a series of shares of Preferred Stock, $.01 par value, designated as
Series A Junior Participating Preferred Stock and filed such designation with
the Secretary of State of Delaware on June 8, 1989, no shares of which have
been issued as of February 9, 1996; and the Board of Directors on February 9,
1996 adopted the following resolution to amend and restate the terms of such
Preferred Stock; and be it further

                 RESOLVED, that pursuant to the authority vested in the Board
of Directors of the Corporation in accordance with the provisions of the
Delaware General Corporation Law and the Certificate of Incorporation, the
Series A Junior Participating Preferred Stock of the Corporation heretofore
created be, and that the designation thereof and the powers, designations,
preferences and relative, participating, optional or other special rights of
the shares of such series, and the qualifications, limitations or restrictions
thereof are hereby amended and restated as follows:

                 Section 1.  Designation and Amount.  The shares of such series
shall be designated as "Series A Junior Participating Preferred Stock" (the
"Series A Preferred Stock") and the number of shares constituting the Series A
Preferred Stock shall be 400,000.  Such number of shares may be increased or
<PAGE>
decreased by resolution of the Board of Directors; provided, that no decrease
shall reduce the number of shares of Series A Preferred Stock to a number less
than the number of shares then outstanding plus the number of shares reserved
for issuance upon the exercise of outstanding options, rights or warrants or
upon the conversion of any outstanding securities issued by the Company
convertible into Series A Preferred Stock.

                 Section 2.  Dividends and Distributions.

                 (A)      Subject to the rights of the holders of any shares of
any series of Preferred Stock of the Company (the "Preferred Stock") (or any
similar stock) ranking prior and superior to the Series A Preferred Stock with
respect to dividends, the holders of shares of Series A Preferred Stock, in
preference to the holders of Common Stock, par value $.01 per share of the
Company (the "Common Stock") and of any other stock of the Company ranking
junior to the Series A Preferred Stock, shall be entitled to receive, when, as
and if declared by the Board of Directors out of funds legally available for
the purpose, quarterly dividends payable in cash on the last day of January,
April, July, and October in each year (each such date being referred to herein
as a "Dividend Payment Date"), commencing on the first Dividend Payment Date
after the first issuance of a share or fraction of a share of Series A
Preferred Stock, in an amount per share (rounded to the nearest cent) equal to
the greater of (a) $1 or (b) subject to the provision for adjustment
hereinafter set forth, 1000 times the aggregate per share amount of all cash
dividends, and 1000 times the aggregate per share amount (payable in kind) of
all non-cash dividends or other distributions other than a dividend payable in
shares of Common Stock, declared on the Common Stock since the immediately
preceding Dividend Payment Date or, with respect to the first Dividend Payment
Date, since the first issuance of any share or fraction of a share of Series A
Preferred Stock.  In the event the Company shall at any time after February 9,
1996, declare or pay any dividend on the Common Stock payable in shares of
Common Stock, or effect a subdivision or combination or consolidation of the
outstanding shares of Common Stock (by reclassification or otherwise than by
payment of a dividend in shares of Common Stock) into a greater or lesser
number of shares of Common Stock, then in each such case the amount to which
holders of shares of Series A Preferred Stock were entitled immediately prior
to such event under clause (b) of the preceding sentence shall be adjusted by
multiplying such amount by a fraction, the numerator of which is the number of
shares of Common Stock outstanding immediately after such event and the
denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

                 (B)      The Company shall declare a dividend or distribution
on the Series A Preferred Stock as provided in paragraph (A) of this Section
immediately after it declares a dividend or distribution on the Common Stock
(other than a dividend payable in shares of Common Stock); provided that, in
the event no dividend or distribution shall have been declared on the Common
Stock during the period between any Dividend Payment Date and the next
subsequent Dividend Payment Date, a dividend of $1 per share on the Series A
Preferred Stock shall nevertheless be payable, when, as and if declared, on
such subsequent Dividend Payment Date.

                 (C)      Dividends shall begin to accrue and be cumulative,
whether or not earned or declared, on outstanding shares of Series A Preferred
Stock from the Dividend Payment Date next preceding the date of issue of such
shares, unless the date of issue of such shares is prior to the record date for
the first Dividend Payment Date, in which case dividends on such shares shall
<PAGE>
begin to accrue from the date of issue of such shares, or unless the date of
issue is a Dividend Payment Date or is a date after the record date for the
determination of holders of shares of Series A Preferred Stock entitled to re-
ceive a quarterly dividend and before such Dividend Payment Date, in either of
which events such dividends shall begin to accrue and be cumulative from such
Dividend Payment Date.  Accrued but unpaid dividends shall not bear interest. 
Dividends paid on the shares of Series A Preferred Stock in an amount less than
the total amount of such dividends at the time accrued and payable on such
shares shall be allocated pro rata on a share-by-share basis among all such
shares at the time outstanding.  The Board of Directors may fix a record date
for the determination of holders of shares of Series A Preferred Stock entitled
to receive payment of a dividend or distribution declared thereon, which record
date shall be not more than 60 days prior to the date fixed for the payment
thereof.

                 Section 3.  Voting Rights.  The holders of shares of Series A
Preferred Stock shall have the following voting rights;

                 (A)      Subject to the provision for adjustment hereinafter
         set forth and except as otherwise provided in the Certificate of
         Incorporation or required by law, each share of Series A Preferred
         Stock shall entitle the holder thereof to 1000 votes on all matters
         upon which the holders of the Common Stock of the Company are entitled
         to vote.  In the event the Company shall at any time after February 9,
         1996, declare or pay any dividend on the Common Stock payable in
         shares of Common Stock, or effect a subdivision or combination or
         consolidation of the outstanding shares of Common Stock (by
         reclassification or otherwise than by payment of a dividend in shares
         of Common Stock) into a greater or lesser number of shares of Common
         Stock, then in each such case the number of votes per share to which
         holders of shares of Series A Preferred Stock were entitled
         immediately prior to such event shall be adjusted by multiplying such
         number by a fraction, the numerator of which is the number of shares
         of Common Stock outstanding immediately after such event and the
         denominator of which is the number of shares of Common Stock that were
         outstanding immediately prior to such event.

                 (B)      Except as otherwise provided herein, in the
         Certificate of Incorporation or in any other Certificate of
         Designations creating a series of Preferred Stock or any similar
         stock, and except as otherwise required by law, the holders of shares
         of Series A Preferred Stock and the holders of shares of Common Stock
         and any other capital stock of the Company having general voting
         rights shall vote together as one class on all matters submitted to a
         vote of stockholders of the Company.

                 (C)      Except as set forth herein, or as otherwise provided
         by law, holders of Series A Preferred Stock shall have no special
         voting rights and their consent shall not be required (except to the
         extent they are entitled to vote with holders of Common Stock as set
         forth herein) for taking any corporate action.

                 Section 4.  Certain Restrictions.

                 (A)  Whenever quarterly dividends or other dividends or
         distributions payable on the Series A Preferred Stock as provided in
         Section 2 are in arrears, thereafter and until all accrued and unpaid
<PAGE>
         dividends and distributions, whether or not earned or declared, on
         shares of Series A Preferred Stock outstanding shall have been paid in
         full, the Company shall not:

                          (i)  declare or pay dividends, or make any other
                 distributions, on any shares of stock ranking junior (as to
                 dividends) to the Series A Preferred Stock;

                     (ii)  declare or pay dividends, or make any other
                 distributions, on any shares of stock ranking on a parity (as
                 to dividends) with the Series A Preferred Stock, except
                 dividends paid ratably on the Series A Preferred Stock and all
                 such parity stock on which dividends are payable or in arrears
                 in proportion to the total amounts to which the holders of all
                 such shares are then entitled;

                    (iii)  redeem or purchase or otherwise acquire for
                 consideration shares of any stock ranking junior (either as to
                 dividends or upon liquidation, dissolution or winding up) to
                 the Series A Preferred Stock, provided that the Company may at
                 any time redeem, purchase or otherwise acquire shares of any
                 such junior stock in exchange for shares of any stock of the
                 Company ranking junior (as to dividends and upon dissolution,
                 liquidation or winding up) to the Series A Preferred Stock or
                 rights, warrants or options to acquire such junior stock;

                     (iv)  redeem or purchase or otherwise acquire for
                 consideration any shares of Series A Preferred Stock, or any
                 shares of stock ranking on a parity (either as to dividends or
                 upon liquidation, dissolution or winding up) with the Series A
                 Preferred Stock, except in accordance with a purchase offer
                 made in writing or by publication (as determined by the Board
                 of Directors) to all holders of such shares upon such terms as
                 the Board of Directors, after consideration of the respective
                 annual dividend rates and other relative rights and
                 preferences of the respective series and classes, shall
                 determine in good faith will result in fair and equitable
                 treatment among the respective series or classes.

                 (B)      The Company shall not permit any subsidiary of the
         Company to purchase or otherwise acquire for consideration any shares
         of stock of the Company unless the Company could, under paragraph (A)
         of this Section 4, purchase or otherwise acquire such shares at such
         time and in such manner.

                 Section 5.  Reacquired Shares.  Any shares of Series A
Preferred Stock purchased or otherwise acquired by the Company in any manner
whatsoever shall be retired and cancelled promptly after the acquisition
thereof.  

                 Section 6.  Liquidation, Dissolution or Winding Up.  Upon any
liquidation, dissolution or winding up of the Company, no distribution shall be
made (A) to the holders of the Common Stock or of shares of any other stock of
the Company ranking junior, upon liquidation, dissolution or winding up, to the
Series A Preferred Stock unless, prior thereto, the holders of shares of Series
A Preferred Stock shall have received $1000 per share, plus an amount equal to
accrued and unpaid dividends and distributions thereon, whether or not earned
<PAGE>
or declared, to the date of such payment, provided that the holders of shares
of Series A Preferred Stock shall be entitled to receive an aggregate amount
per share, subject to the provision for adjustment hereinafter set forth, 
equal to 1000 times the aggregate amount to be distributed per share to holders
of shares of Common Stock, or (B) to the holders of shares of stock ranking on
a parity upon liquidation, dissolution or winding up with the Series A
Preferred Stock, except distributions made ratably on the Series A Preferred
Stock and all such parity stock in proportion to the total amounts to which the
holders of all such shares are entitled upon such liquidation, dissolution or
winding up.  In the event the Company shall at any time after February 9, 1996
declare or pay any dividend on the Common Stock payable in shares of Common
Stock, or effect a subdivision or combination or consolidation of the
outstanding shares of Common Stock (by reclassification or otherwise than by
payment of a dividend in shares of Common Stock) into a greater or lesser
number of shares of Common Stock, then in each such case the aggregate amount
to which holders of shares of Series A Preferred Stock were entitled
immediately prior to such event under the proviso in clause (A) of the
preceding sentence shall be adjusted by multiplying such amount by a fraction
the numerator of which is the number of shares of Common Stock outstanding
immediately after such event and the denominator of which is the number of
shares of Common Stock that were outstanding immediately prior to such event.

                 Section 7.  Consolidation, Merger, etc.  In case the Company
shall enter into any consolidation, merger, combination or other transaction in
which the shares of Common Stock are converted into, exchanged for or changed
into other stock or securities, cash and/or any other property, then in any
such case each share of Series A Preferred Stock shall at the same time be
similarly converted into, exchanged for or changed into an amount per share
(subject to the provision for adjustment hereinafter set forth) equal to 1000
times the aggregate amount of stock, securities, cash and/or any other property
(payable in kind), as the case may be, into which or for which each share of
Common Stock is converted, exchanged or converted.  In the event the Company
shall at any time after February 9, 1996 declare or pay any dividend on the
Common Stock payable in shares of Common Stock, or effect a subdivision or
combination or consolidation of the outstanding shares of Common Stock (by
reclassification or otherwise than by payment of a dividend in shares of Common
Stock) into a greater or lesser number of shares of Common Stock, then in each
such case the amount set forth in the preceding sentence with respect to the
conversion, exchange or change of shares of Series A Preferred Stock shall be
adjusted by multiplying such amount by a fraction, the numerator of which is
the number of shares of Common Stock outstanding immediately after such event
and the denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

                 Section 8.  No Redemption. The shares of Series A Preferred
Stock shall not be redeemable from any holder.

                 Section 9.  Rank.  The Series A Preferred Stock shall rank,
with respect to the payment of dividends and the distribution of assets upon
liquidation, dissolution or winding up of the Company, junior to all other
series of Preferred Stock and senior to the Common Stock. 

                 Section 10.  Amendment.  If any proposed amendment to the
Certificate of Incorporation (including this Certificate of Designations) would
alter, change or repeal any of the preferences, powers or special rights given
to the Series A Preferred Stock so as to affect the Series A Preferred Stock
adversely, then the holders of the Series A Preferred Stock shall be entitled
<PAGE>
to vote separately as a class upon such amendment, and the affirmative vote of
two-thirds of the outstanding shares of the Series A Preferred Stock, voting
separately as a class, shall be necessary for the adoption thereof, in addition
to such other vote as may be required by the General Corporation Law of the
State of Delaware.
<PAGE>
                 IN WITNESS WHEREOF, this Amended Certificate of Designations is
executed on behalf of the Company by its Executive Vice President and Chief
Financial Officer and attested by its Secretary this 9th day of February, 1996.

         UNDER CERTAIN CIRCUMSTANCES, AS SET FORTH IN THE RIGHTS AGREEMENT,
         RIGHTS OWNED BY OR TRANSFERRED TO ANY PERSON WHO BECOMES AN ACQUIRING
         PERSON (AS DEFINED IN THE RIGHTS AGREEMENT) AND CERTAIN TRANSFEREES
         THEREOF WILL BECOME NULL AND VOID AND WILL NO LONGER BE TRANSFERABLE.

                          SUMMARY OF RIGHTS TO PURCHASE
                            Shares of Preferred Stock

                 On February 9, 1996, the Board of Directors of Cadence Design
Systems, Inc. (the "Company") declared a dividend of one preferred share
purchase right (a "Right") for each outstanding share of common stock, par
value $.01 per share, of the Company (the "Common Stock").  The dividend is
payable on February 20, 1996 (the "Record Date") to the stockholders of record
on that date.  Each Right entitles the registered holder to purchase from the
Company one one-thousandth of a share of Series A Junior Participating
Preferred Stock, par value $.01 per share (the "Preferred Stock") of the
Company at a price of $240 per one one-thousandth of a share of Preferred Stock
(the "Purchase Price"), subject to adjustment.  The description and terms of
the Rights are set forth in a Rights Agreement dated as of February 9, 1996, as
the same may be amended from time to time (the "Rights Agreement"), between the
Company and Harris Trust and Savings Bank, as Rights Agent (the "Rights
Agent").  The rights issued under the old amended and restated rights
agreement, dated as of June 20, 1989, between the Company and the Rights agent
expired on February 9, 1996.

                 Until the earlier to occur of (i) 10 days following a public
announcement that a person or group of affiliated or associated persons (an
"Acquiring Person") have acquired beneficial ownership of 15% or more of the
outstanding shares of Common Stock or (ii) 10 business days (or such later date
as may be determined by action of the Board of Directors prior to such time as
any person or group of affiliated persons becomes an Acquiring Person)
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 15% or more of the outstanding
shares of Common Stock (the earlier of such dates being called the
"Distribution Date"), the Rights will be evidenced, with respect to any of the
Common Stock certificates outstanding as of the Record Date, by such Common
Stock certificate together with a copy of this Summary of Rights.

                 The Rights Agreement provides that, until the Distribution
Date (or earlier redemption or expiration of the Rights), the Rights will be
transferred with and only with the Common Stock.  Until the Distribution Date
(or earlier redemption or expiration of the Rights), new Common Stock
certificates issued after the Record Date upon transfer or new issuances of
Common Stock will contain a notation incorporating the Rights Agreement by
reference.  Until the Distribution Date (or earlier redemption or expiration of
the Rights), the surrender for transfer of any certificates for shares of
Common Stock outstanding as of the Record Date, even without such notation or a
copy of this Summary of Rights, will also constitute the transfer of the Rights
associated with the shares of Common Stock represented by such certificate.  As
soon as practicable following the Distribution Date, separate certificates
evidencing the Rights ("Right 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 Right Certificates alone will evidence the Rights.
<PAGE>
                 The Rights are not exercisable until the Distribution Date. 
The Rights will expire on February 9, 2006 (the "Final Expiration Date"),
unless the Final Expiration Date is extended or unless the Rights are earlier
redeemed or exchanged by the Company, in each case as described below.

                 The Purchase Price payable, and the number of shares of
Preferred Stock or other securities or property issuable, upon exercise of the
Rights are subject to adjustment from time to time to prevent dilution (i) in
the event of a stock dividend on, or a subdivision, combination or
reclassification of, the Preferred Stock, (ii) upon the grant to holders of the
Preferred Stock of certain rights or warrants to subscribe for or purchase
Preferred Stock at a price, or securities convertible into Preferred Stock with
a conversion price, less than the then-current market price of the Preferred
Stock or (iii) upon the distribution to holders of the Preferred Stock of
evidences of indebtedness or assets (excluding regular periodic cash dividends
or dividends payable in Preferred Stock) or of subscription rights or warrants
(other than those referred to above).

                 The number of outstanding Rights are also subject to adjustment
in the event of a stock split of the Common Stock or a stock dividend on the
Common Stock payable in shares of Common Stock or subdivisions, consolidations
or combinations of the Common Stock occurring, in any such case, prior to the
Distribution Date.

                 Shares of Preferred Stock purchasable upon exercise of the
Rights will not be redeemable.  Each share of Preferred Stock will be entitled,
when, as and if declared, to a minimum preferential quarterly dividend payment
of $1 per share but will be entitled to an aggregate dividend of 1000 times the
dividend declared per share of Common Stock.  In the event of liquidation, the
holders of the Preferred Stock will be entitled to a minimum preferential
liquidation payment of $1000 per share (plus any accrued but unpaid dividends)
but will be entitled to an aggregate payment of 1000 times the payment made per
share of Common Stock.  Each share of Preferred Stock will have 1000 votes,
voting together with the Common Stock.  Finally, in the event of any merger,
consolidation or other transaction in which shares of Common Stock are
converted or exchanged, each share of Preferred Stock will be entitled to
receive 1000 times the amount received per share of Common Stock.  These rights
are protected by customary antidilution provisions.

                 Because of the nature of the Preferred Stock's dividend,
liquidation and voting rights, the value of the one one-thousandth interest in
a share of Preferred Stock purchasable upon exercise of each Right should
approximate the value of one share of Common Stock.

                 In the event that any person or group of affiliated or
associated persons becomes an Acquiring Person, each holder of a Right, other
than Rights beneficially owned by the Acquiring Person (which will thereupon
become void), will thereafter have the right to receive upon exercise of a
Right at the then current exercise price of the Right, that number of shares of
Common Stock having a market value of two times the exercise price of the
Right.

                 In the event that, after a person or group has become an
Acquiring Person, the Company is acquired in a merger or other business
combination transaction or 50% or more of its consolidated assets or earning
power are sold, proper provision will be made so that each holder of a Right
(other than Rights beneficially owned by an Acquiring Person which will have
<PAGE>
become void) will thereafter have the right to receive, upon the exercise
thereof at the then current exercise price of the Right, that number of shares
of common stock of the person with whom the Company has engaged in the
foregoing transaction (or its parent), which number of shares at the time of
such transaction will have a market value of two times the exercise price of
the Right.  

                 At any time after any person or group becomes an Acquiring
Person and prior to the acquisition by such person or group of 50% or more of
the outstanding shares of Common Stock or the occurrence of an event described
in the prior paragraph, the Board of Directors of the Company may exchange the
Rights (other than Rights owned by such person or group which will have become
void), in whole or in part, at an exchange ratio of one share of Common Stock,
or one one-thousandth of a share of Preferred Stock (or of a share of a class
or series of the Company's preferred stock having equivalent rights,
preferences and privileges), per Right (subject to adjustment).

                 With certain exceptions, no adjustment in the Purchase Price
will be required until cumulative adjustments require an adjustment of at least
1% in such Purchase Price.  No fractional shares of Preferred Stock will be
issued (other than fractions which are integral multiples of one one-thousandth
of a share of Preferred Stock, which may, at the election of the Company, be
evidenced by depositary receipts) and in lieu thereof, an adjustment in cash
will be made based on the market price of the Preferred Stock on the last
trading day prior to the date of exercise.

                 At any time prior to the time an Acquiring Person becomes such,
the Board of Directors of the Company may redeem the Rights in whole, but not
in part, at a price of $.01 per Right (the "Redemption Price").  The redemption
of the Rights may be made effective at such time, on such basis and with such
conditions as the Board of Directors in its sole discretion may establish. 
Immediately upon any redemption of the Rights, the right to exercise the Rights
will terminate and the only right of the holders of Rights will be to receive
the Redemption Price.

                 For so long as the Rights are then redeemable, the Company may,
except with respect to the redemption price, amend the Rights in any manner. 
After the Rights are no longer redeemable, the Company may, except with respect
to the redemption price, amend the Rights in any manner that does not adversely
affect the interests of holders of the Rights. 

                 Until a Right is exercised, the holder thereof, as such, will
have no rights as a stockholder of the Company, including, without limitation,
the right to vote or to receive dividends.

                 A copy of the Rights Agreement has been filed with the
Securities and Exchange Commission as an Exhibit to a Registration Statement on
Form 8-A.  A copy of the Rights Agreement is available free of charge from the
Company.  This summary description of the Rights does not purport to be
complete and is qualified in its entirety by reference to the Rights Agreement,
as the same may be amended from time to time, which is hereby incorporated
herein by reference.

                 The Rights have been issued in place of the Company's previous
common share purchase rights issued in 1989.  The principal differences between
the old rights and the new Rights are (1) the new Rights are exercisable for
shares of Preferred Stock instead of Common Stock, (2) an increase in the
<PAGE>
exercise price from $66.67 (as adjusted to reflect the Company's stock split)
to $240 per share; (3) the reduction in the threshold percentage from 20% to
15%; and (4) the elimination of a provision in the old rights plan permitting
redemption of the rights during the 10 days after a person or group becomes an
Acquiring Person.

                        CADENCE DESIGN SYSTEMS ADOPTS NEW
                             STOCKHOLDER RIGHTS PLAN

SAN JOSE, Calif., February 9, 1995 --  Cadence Design Systems, Inc. (NYSE: 
CDN) announced today that its Board of Directors has adopted a Revised
Stockholder Rights Plan.  The principal modifications effected by the new plan
are the conversion to a preferred stock plan, the increase in the exercise
price of the rights and the lowering of the threshold percentage to 15%.

          Joseph B. Costello, President and Chief Executive Officer, explained
that "the conversion to a preferred stock rights plan allows the Company to
free up its authorized capital for future issuance and the exercise price of
the revised plan more properly reflects the Board's view of the long-term value
of the Company's common stock."  The new Rights Plan also incorporates other
refinements to the plan.

          Mr. Costello noted that "the revised Rights Plan was not adopted in
response to any takeover approaches or any other similar developments.  It was
adopted because the Board believes that it represents a sound and reasonable
means of safeguarding the interests of all of the Company's stockholders.  The
new Rights Plan should provide increased protection against coercive or unfair
takeover tactics, while not foreclosing a full and fair acquisition bid.  The
Rights Plan should encourage any potential acquiror to negotiate with the Board
of Directors prior to crossing the 15% ownership threshold set by the Rights
Plan (the old rights plan had a 20% threshold), thereby giving the Board the
means to preserve full value for all of the Company's stockholders."

          The dividend of one Right for each share of the Company's outstanding
common stock is payable on February 20, 1996 to common stockholders of record
as of the close of business on that date (rights issued under the old rights
plan will expire at the close of business on February 9, 1996).

          Details of the Rights distribution are contained in a summary that is
being mailed to all stockholders of the Company.
