                                    EXHIBIT A
                              AMENDED AND RESTATED
                          CERTIFICATE OF INCORPORATION
                                       OF
                             WIND RIVER SYSTEMS, INC.

                                       I.

         The name of this corporation is Wind River Systems, Inc.

                                       II.

The address, including street, number, city and county of the registered
officer of the corporation in the State of Delaware is 32 Lockerman Square,
Suite L-100, City of Dover 19901, County of Kent; and the name of the
registered agent of the corporation in the State of Delaware at such address
is the Prentice-Hall Corporation System, Inc.

                                      III.

         The purpose of this corporation is to engage in any lawful act or
activity for which a corporation may be organized under the Delaware General
Corporation Law.

                                      IV.

     1. This corporation is authorized to issue Twenty-Two Million
(22,000,000) shares of its capital stock, which shall be divided into two
classes of stock designated "Common Stock" and "Preferred Stock." The total
number of shares of Common Stock which the corporation is authorized to issue
is Twenty Million (20,000,000) shares, each having a par value of one tenth
of one cent ($.001). The total number of shares of Preferred Stock which the
corporation is authorized to issue is Two Million (2,000,000), each having a
par value of one tenth of one percent ($.001).

     2. The Preferred Stock may be issued from time to time in one or more
series. The Board of Directors is hereby authorized, by filing a certificate
pursuant to the Delaware General Corporation Law, to fix or alter from time
to time the designation, powers, preferences and rights of the shares of each
such series and the qualifications, limitations or restrictions thereof,
including without limitation the dividend rights, dividend rate, conversion
rights, voting rights, rights and terms of redemption (including sinking fund
provisions), redemption price or prices, and the liquidation preferences of
any wholly unissued series of Preferred Stock, and to establish from time to
time the number of shares constituting any such series and the designation
thereof, or any of them (a "Preferred Stock Designation"); and to increase or
decrease the number of shares of any series subsequent to the issuance of
shares of that series, but not below the number of shares of such series then
outstanding. In case the number of shares of any series shall be so
decreased, the shares constituting such decrease shall resume the status that
they had prior to the adoption of the resolution originally fixing the number
of shares of such series.

         No share or shares of any series of Preferred Stock acquired by the
Corporation by reason of redemption, purchase, conversion or otherwise
shall be reissued as part of such series, and the Board of Directors is
authorized, pursuant to Section 243 of the Delaware General

                                       2.



Corporation law, to retire any such share or shares. The retirement of any
such share or shares shall not reduce the total authorized number of shares
of Preferred Stock.

                                       V.

         For the management of the business and for the conduct of the
affairs of the corporation, and in further definition, limitation and
regulation of the powers of the corporation, of its directors and of its
stockholders or any claim thereof, as the case may be, it is further provided
that:

     1. The management of the business and the conduct of the affairs of the
corporation shall be vested in its Board of Directors. The number of
directors which shall constitute the whole Board of Directors shall be fixed
exclusively by one or more resolutions adopted by the Board of Directors.

         Each director shall serve until his successor is duly elected and
qualified or until his death, registration or removal. No decrease in the
number of directors constituting the Board of Directors shall shorten the
term of the incumbent director.

         Any vacancies on the Board of Directors resulting from death,
resignation, disqualification, removal or other causes shall be filled by
either (i) the affirmative vote of the holders of a majority of the voting
power of the then-outstanding shares of voting stock of the corporation
entitled to vote generally in the election of directors (the "Voting Stock")
voting together as a single class; or (ii) by the affirmative vote of a
majority of the remaining directors then in office, even though less than a
quorum of the Board of Directors. Newly created directorships resulting from
any increase in the number of directors shall, unless the Board of Directors
determines by resolution that any such newly created directorship shall be
filled by the stockholders, be filled only by the affirmative vote of the
directors then in office, even though less than a quorum of the Board of
Directors. Any director elected in accordance with the preceding sentence
shall hold office until such director's successor shall have been elected and
qualified.

     2. The Bylaws may be altered or amended or new Bylaws adopted by the
affirmative vote of at least sixty-six and two-thirds percent (66-2/3%) of
the voting power of all of the then-outstanding shares of the Voting Stock.
In furtherance and not in limitation of the power conferred by statute, the
Board of Directors is expressly authorized to adopt, amend, supplement or
repeal the Bylaws.

     3. The directors of the corporation need not be elected by written
ballot unless the Bylaws so provide.

     4. No action shall be taken by the stockholders of the corporation
except at an annual or special meeting of stockholders called in accordance
with the Bylaws and no action shall be taken by the stockholders by written
consent.

     5. Advance notice of stockholder nominations for the election of
directors and of business to be brought by stockholders before any meeting of
the stockholders of the corporation shall be given in the manner provided in
the Bylaws of the corporation.


                                       3.



     6. Any director, or the entire Board of Directors, may be removed from
office at any time (i) with cause by the affirmative vote of the holders of
at least a majority of the voting power of all of the then-outstanding shares
of the Voting Stock, voting together as a single class; or (ii) without cause
by the affirmative vote of the holders of at least sixty-six and two-thirds
percent (66-2/3%) of the voting power of all of the then-outstanding shares
of the Voting Stock.

                                       VI.

         A director of the corporation shall, to the full extent not
prohibited by the General Corporation Law of the State of Delaware, as the
same exists or may hereafter be amended, not be liable to the corporation or
its stockholders for monetary damages for breach of his or her fiduciary duty
as a director.

                                      VII.

         Notwithstanding any other provisions of this Certificate of
Incorporation or any provision of law which might otherwise permit a lesser
vote or no vote, but in addition to any affirmative vote of the holders of
any particular class or series of the Voting Stock required by law, this
Certificate of Incorporation or any Preferred Stock Designation, the
affirmative vote of the holders of at least sixty-six and two-thirds percent
(66-2/3%) of the voting power of all of the then-outstanding shares of the
Voting Stock, voting together as a single class, shall be required to alter,
amend or repeal Article VI.

                                      VIII.

         The corporation is to have perpetual existence.

                                       IX.

         The corporation reserves the right to amend, alter, change or repeal
any provision contained in this Certificate of Incorporation, in the manner
now or hereafter prescribed by statute, and all rights conferred upon the
stockholders herein are granted subject to this right.




                                       4.

                          CERTIFICATE OF DESIGNATION

                                      OF

                 SERIES A JUNIOR PARTICIPATING PREFERRED STOCK

                        (PURSUANT TO SECTION 151 OF THE
                       DELAWARE GENERAL CORPORATION LAW)

         WIND RIVER 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 adopted by the
Board of Directors of the Corporation as required by Section 151 of the
General Corporation Law at a meeting duly called and held on October 21, 1999:

                           RESOLVED, that pursuant to the authority granted to
                  and vested in the Board of Directors of the Company in
                  accordance with the provisions of its Amended and Restated
                  Certificate of Incorporation, the Board of Directors hereby
                  creates a series of Preferred Stock, par value $.001 per
                  share, of the Company and hereby states the designation and
                  number of shares, and fixes the relative designations and the
                  powers, preferences and rights, and the qualifications,
                  limitations and restrictions thereof (in addition to the
                  provisions set forth in the Certificate of Incorporation of
                  the Company, which are applicable to the Preferred Stock of
                  all classes and series), as follows:

SERIES A JUNIOR PARTICIPATING PREFERRED STOCK:

     SECTION 1.  DESIGNATION AND AMOUNT.  One Million Two Hundred Fifty
Thousand (1,250,000) shares of Preferred Stock, $.001 par value, are
designated "Series A Junior Participating Preferred Stock" with the
designations and the powers, preferences and rights, and the qualifications,
limitations and restrictions specified herein (the "Junior Preferred Stock").
Such number of shares may be increased or decreased by resolution of the
Board of Directors; PROVIDED, that no decrease shall reduce the number of
shares of Junior 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 Junior
Preferred Stock.

     SECTION 2.  DIVIDENDS AND DISTRIBUTIONS.

            (A)  Subject to the rights of the holders of any shares of any
series of Preferred Stock (or any similar stock) ranking prior and superior
to the Junior Preferred Stock with respect to dividends, the holders of
shares of Junior Preferred Stock, in preference to the holders of


                                      A-1



Common Stock, par value $.001 per share (the "Common Stock"), of the Company,
and of any other junior 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 first day of April, July,
October and January in each year (each such date being referred to herein as
a "Quarterly Dividend Payment Date"), commencing on the first Quarterly
Dividend Payment Date after the first issuance of a share or fraction of a
share of Junior Preferred Stock, in an amount per share (rounded to the
nearest cent) equal to the greater of (a) $l.00 or (b) subject to the
provision for adjustment hereinafter set forth, 100 times the aggregate per
share amount of all cash dividends, and 100 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 or a subdivision of
the outstanding shares of Common Stock (by reclassification or otherwise),
declared on the Common Stock since the immediately preceding Quarterly
Dividend Payment Date or, with respect to the first Quarterly Dividend
Payment Date, since the first issuance of any share or fraction of a share of
Junior Preferred Stock. In the event the Company shall at any time 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 Junior 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 Junior
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 Quarterly Dividend Payment Date and the next
subsequent Quarterly Dividend Payment Date, a dividend of $1.00 per share on
the Junior Preferred Stock shall nevertheless be payable on such subsequent
Quarterly Dividend Payment Date.

     (C)  Dividends shall begin to accrue and be cumulative on outstanding
shares of Junior Preferred Stock from the Quarterly 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 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 Junior 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 Junior
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 Junior Preferred


                                      A-2



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 Junior Preferred
Stock shall have the following voting rights:

            (A)  Subject to the provision for adjustment hereinafter set
forth, each share of Junior Preferred Stock shall entitle the holder thereof
to 100 votes on all matters submitted to a vote of the stockholders of the
Company. In the event the Company shall at any time 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 Junior 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 any other
Certificate of Designation creating a series of Preferred Stock or any
similar stock, or by law, the holders of shares of Junior 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 Junior 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 Junior 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 Junior 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 (either as to dividends
or upon liquidation, dissolution or winding up) to the Junior Preferred Stock;

                 (ii) declare or pay dividends, 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 Junior
Preferred Stock, except dividends paid ratably on the Junior 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;


                                      A-3



                 (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 Junior 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 (either as to dividends or upon dissolution,
liquidation or winding up) to the Junior Preferred Stock; or

                 (iv)  redeem or purchase or otherwise acquire for
consideration any shares of Junior Preferred Stock, or any shares of stock
ranking on a parity (either as to dividends or upon liquidation, dissolution
or winding up) with the Junior 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 Junior Preferred Stock
purchased or otherwise acquired by the Company 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 subject to the conditions and restrictions on issuance set forth
herein, in the Amended and Restated Certificate of Incorporation, or in any
other Certificate of Designation creating a series of Preferred Stock or any
similar stock or as otherwise required by law.

     SECTION 6.  LIQUIDATION, DISSOLUTION OR WINDING UP.  Upon any
liquidation, dissolution or winding up of the Company, no distribution shall
be made (1) to the holders of shares of stock ranking junior (either as to
dividends or upon liquidation, dissolution or winding up) to the Junior
Preferred Stock unless, prior thereto, the holders of shares of Junior
Preferred Stock shall have received $100 per share, plus an amount equal to
accrued and unpaid dividends and distributions thereon, whether or not
declared, to the date of such payment, provided that the holders of shares of
Junior Preferred Stock shall be entitled to receive an aggregate amount per
share, subject to the provision for adjustment hereinafter set forth, equal
to 100 times the aggregate amount to be distributed per share to holders of
shares of Common Stock, or (2) to the holders of shares of stock ranking on a
parity (either as to dividends or upon liquidation, dissolution or winding
up) with the Junior Preferred Stock, except distributions made ratably on the
Junior 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 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 Junior


                                      A-4



Preferred Stock were entitled immediately prior to such event under the
proviso in clause (1) 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 exchanged for or changed into other stock or
securities, cash and/or any other property, then in any such case each share
of Junior Preferred Stock shall at the same time be similarly exchanged or
changed into an amount per share, subject to the provision for adjustment
hereinafter set forth, equal to 100 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 Company shall at any time 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 exchange or change of shares of Junior 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 Junior Preferred Stock shall
not be redeemable.

     SECTION 9.  RANK.  The Junior Preferred Stock shall rank, with respect
to the payment of dividends and the distribution of assets, junior to all
series of any other class of the Company's Preferred Stock.

     SECTION 10. AMENDMENT.  The Amended and Restated Certificate of
Incorporation of the Company shall not be amended in any manner which would
materially alter or change the powers, preferences or special rights of the
Junior Preferred Stock so as to affect them adversely without the affirmative
vote of the holders of at least two-thirds of the outstanding shares of
Junior Preferred Stock, voting together as a single class.
