Pursuant to Section 151 of the General Corporation Law of the State of
Delaware

We, Joseph J. Sweeney, Vice President, Legal Affairs and
Intellectual Property, and Barry Quan, Assistant Secretary, of Applied
Materials, Inc., organized and existing under the General Corporation
Law of the State of Delaware, in accordance with the provisions of
Section 103 thereof, DO HEREBY CERTIFY:

That pursuant to the authority conferred upon the Board of
Directors by the Certificate of Incorporation of the Corporation, the
Board of Directors on July 7, 1999, adopted the following resolution
creating a series of One Hundred Ten Thousand (110,000) shares of
Preferred Stock designated as Series A Junior Participating Preferred
Stock:

RESOLVED, that pursuant to the authority vested in the Board of
Directors of the Corporation in accordance with the provisions of its
Certificate of Incorporation, a series of Preferred Stock of the
Corporation be and it hereby is created, and that the designation and
amount thereof and the voting powers, preferences and relative,
participating, optional and other special rights of the shares of such
series, and the qualifications, limitations or restrictions thereof are
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
such series shall be One Hundred Ten Thousand (110,000).

Section 2.  Dividends and Distributions.

(A)     The dividend rate on the shares of Series A Preferred Stock
shall be for each quarterly dividend (hereinafter referred to as a
"quarterly dividend period"), which quarterly dividend periods shall
commence on February 1, May 1, August 1 and November 1, in each year
(each such date being referred to herein as a "Quarterly Dividend
Payment Date") (or in the case of original issuance, from the date of
original issuance) and shall end on and include the day next preceding
the first date of the next quarterly dividend period, at a rate per
quarterly dividend period (rounded to the nearest cent) equal to the
greater of (a) $1.00 or (b) subject to the provisions for adjustment
hereinafter set forth, 10,000 times the aggregate per share amount of
all cash dividends, and 10,000 times the aggregate per share amount
(payable in cash, based upon the fair market value at the time the non-
cash dividend or other distribution is declared as determined in good
faith by the Board of Directors) of all non-cash dividends or other
distributions other than a dividend payable in shares of Common Stock,
par value $0.01 per share, of the Corporation (the "Common Stock"), or
a subdivision of the outstanding shares of Common Stock (by
reclassification or otherwise), declared (but not withdrawn) on the
Common Stock during the immediately preceding quarterly dividend period,
or, with respect to the first quarterly dividend period, since the first
issuance of any share or fraction of a share of Series A Preferred
Stock.  In the event the Corporation shall at any time after July 7,
1999 (the "Rights Declaration Date") (i) declare any dividend on
Common Stock payable in shares of Common Stock, (ii) subdivide the
outstanding Common Stock, or (iii) combine the outstanding Common Stock
into a smaller number of shares, 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)     Dividends shall begin to accrue and be cumulative on
outstanding shares of Series A Preferred Stock from the Quarterly
Dividend Payment Date next preceding the date of issue of such shares of
Series A Preferred Stock, unless the date of issue of such shares is
prior to the record date for the first quarterly Dividend Payment Date,
in which case dividends on such shares shall begin to accrue from the
date of issue of such shares, or unless the date of issue is a Quarterly
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 receive a quarterly dividend and before such Quarterly Dividend
Payment Date, in either of which events such dividends shall begin to
accrue and be cumulative from such Quarterly 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 no more than 45 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, each share of Series A Preferred Stock shall entitle the holder
thereof to 10,000 votes on all matters submitted to a vote of the
stockholders of the Corporation.  In the event the Corporation shall at
any time after the Rights Declaration Date (i) declare any dividend on
Common Stock payable in shares of Common Stock, (ii) subdivide the
outstanding Common Stock, or (iii) combine the outstanding Common Stock
into a smaller number of shares, 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 by law, the holders of shares of Series A Preferred
Stock and the holders of shares of Common Stock shall vote together as
one class on all matters submitted to a vote of stockholders of the
Corporation.

(C)     Except as set forth herein, in the Certificate of
Incorporation and in the Bylaws, 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.  Reacquired Shares.  Any shares of Series A Preferred
Stock purchased or otherwise acquired by the Corporation in any manner
whatsoever shall be retired and cancelled promptly after the acquisition
thereof.  All such shares shall upon their cancellation become
authorized but unissued shares of Preferred Stock and may be reissued as
part of a new series of Preferred Stock to be created by resolution or
resolutions of the Board of Directors, subject to the conditions and
restrictions on issuance set forth herein.

Section 5.  Liquidation, Dissolution or Winding Up.

(A)     In the event of any voluntary or involuntary liquidation,
dissolution or winding up of the Corporation, the holders of the
Series A Preferred Stock shall be entitled to receive, prior to any
distribution (either as dividends or upon liquidation, dissolution or
winding up) to the holders of stock ranking junior to the Series A
Preferred Stock, the greater of (a) $1.00 per share, plus accrued
dividends to the date of distribution, whether or not earned or
declared, or (b) an amount per share, subject to the provision for
adjustment hereinafter set forth, equal to 10,000 times the aggregate
amount to be distributed per share to holders of Common Stock.  In the
event the Corporation shall at any time after the Rights Declaration
Date (i) declare any dividend on Common Stock payable in shares of
Common Stock, (ii) subdivide the outstanding Common Stock, or
(iii) combine the outstanding Common Stock into a smaller number of
shares, then in each such case the amount to which holders of shares of
Series A Preferred Stock were entitled immediately prior to such event
pursuant to 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.

Section 6.  Consolidation, Merger, etc.  In case the Corporation
shall enter into any consolidation, merger, combination or other
transaction in which the shares of Common Stock are exchanged for or
changed into other stock or securities, cash and/or any other property,
then in any such case the shares of Series A Preferred Stock shall at
the same time be similarly exchanged or changed in an amount per share
(subject to the provision for adjustment hereinafter set forth) equal to
10,000 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 changed or exchanged.  In the event
the Corporation shall at any time after the Rights Declaration Date
(i) declare any dividend on Common Stock payable in shares of Common
Stock, (ii) subdivide the outstanding Common Stock, or (iii) combine the
outstanding Common Stock into a smaller number of shares, then in each
such case the amount set forth in the preceding sentence with respect to
the 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 7.  No Redemption.  The shares of Series A Preferred Stock
shall not be redeemable.

Section 8.  Fractional Shares.  Series A Preferred Stock may be
issued in fractions of a share which shall entitle the holder, in
proportion to such holder's fractional shares, to exercise voting
rights, receive dividends, participate in distributions and have the
benefit of all other rights of holders of Series A Preferred Stock.  All
payments made with respect to fractional shares hereunder shall be
rounded to the nearest whole cent.

Section 9.  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
dividends and distributions, whether or not declared, on shares of
Series A Preferred Stock outstanding shall have been paid in full, the
Corporation shall not:
(i)     declare or pay dividends on, make any other
distributions on, or redeem or purchase or otherwise acquire for
consideration any shares of stock ranking junior (either as to
dividends or upon liquidation, dissolution or winding up) to the
Series A Preferred Stock;
(ii)    declare or pay dividends on or make any other
distributions on 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 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 on a parity (either as
to dividends or upon liquidation, dissolution or winding up) with
the Series A Preferred Stock, provided that the Corporation may at
any time redeem, purchase or otherwise acquire shares of any such
parity stock in exchange for shares of any stock of the
Corporation ranking junior (either as to dividends or upon
dissolution, liquidation or winding up) to the Series A Preferred
Stock; or
(iv)    purchase or otherwise acquire for consideration any
shares of Series A Preferred Stock, or any shares of stock ranking
on a parity 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 Corporation shall not permit any subsidiary of the
Corporation to purchase or otherwise acquire for consideration any
shares of stock of the Corporation unless the Corporation could, under
paragraph (A) of this Section 9, purchase or otherwise acquire such
shares at such time and in such manner.

Section 10.  Ranking.  The Series A Preferred Stock shall be
junior to all other Series of the Corporation's preferred stock as to
the payment of dividends and the distribution of assets, except to the
extent a series is made pari passu with the Series A Preferred Stock.

Section 11.  Amendment.  The Certificate of Incorporation of the
Corporation shall not be amended in any manner which would materially
alter or change the powers, preferences or special rights of the Series
A Preferred Stock so as to affect them adversely without the affirmative
vote of the holders of two-thirds or more of the outstanding shares of
Series A Preferred Stock voting together as a single class.

IN WITNESS WHEREOF, we have executed and subscribed this
Certificate and do affirm the foregoing as true under the penalties of
perjury this 9th day of July, 1999.
