                            INTEGRATED SYSTEMS, INC.

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


Joseph Addiego and Narendra K. Gupta, certify that:

       1. They are the Chief  Executive  Officer  and  Chairman  and  Secretary,
respectively, of Integrated Systems, Inc., a California corporation.

       2. At a duly  noticed and held  meeting of the Board of  Directors of the
corporation  held on September  24, 1998,  the following  resolutions  were duly
adopted:

         RESOLVED,  that pursuant to the authority  granted to and vested in the
Board of  Directors  of this  Corporation  (hereinafter  called  the  "Board  of
Directors" or the "Board") in accordance  with the provisions of the Articles of
Incorporation of the Corporation, the Board of Directors hereby creates a series
of preferred stock, no par value (the "Preferred Stock"), of the Corporation and
hereby  states the  designation  and number of  shares,  and fixes the  relative
rights, preferences, and limitations thereof as follows:

         Series A Junior Participating Preferred Stock:

         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 500,000.  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  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  Corporation
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 (or any other stock) ranking prior and superior to the
Series A Preferred  Stock with  respect to  dividends,  the holders of shares of
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 first day of March, June,  September
and  December  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
Series A  Preferred  Stock,  in an  amount  (if any) per share  (rounded  to the
nearest cent),  subject to the provision for




adjustment  hereinafter  set forth,  equal to 200 times the  aggregate per share
amount  of all cash  dividends,  and 200 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, no par value (the "Common  Stock"),
of the Company 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 Series A Preferred  Stock.  In the event the  Corporation
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 Series A Preferred Stock were entitled immediately prior to
such event under 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  Corporation  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).

                  (C)  Dividends  due pursuant to paragraph  (A) of this Section
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, 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 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,  each share of Series A Preferred  Stock shall entitle the holder thereof
to 200  votes on all  matters  submitted  to a vote of the  shareholders  of the
Corporation.  In the event the Corporation  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
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 


                                       2


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 Determination creating a series of Preferred Stock or any similar
stock,  or 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 Corporation
having  general  voting  rights shall vote  together as one class on all matters
submitted to a vote of shareholders of the Corporation.

                  (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  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,  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 Series A 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 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; or

                           (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  Corporation  may at any time  redeem,  purchase or otherwise
acquire  shares of any such junior  stock in exchange for shares of any stock of
the  Corporation   ranking  junior  (as  to  dividends  and  upon   dissolution,
liquidation or winding up) to the Series A Preferred Stock.

                  (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 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  Corporation  in any manner  whatsoever
shall be retired and canceled 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
Certificate  of  Incorporation,  or in any other  Certificate  of  Determination
creating  a series  of  Preferred  Stock or any  similar  stock or as  otherwise
required by law.

                                       3


         Section 6. Liquidation, Dissolution or Winding Up.

                  (A) Upon any  liquidation,  dissolution  or  winding up of the
Corporation, the holders of shares of Series A Preferred Stock shall be entitled
to receive,  prior and in  preference to any  distribution  of any assets of the
Corporation  to the holders of Common  Stock,  the amount of $2.00 per share for
each  share of  Series A  Preferred  Stock  then held by them.  Thereafter,  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 200 times the aggregate  amount to be distributed per share
to holders of shares of Common  Stock plus an amount  equal to any  accrued  and
unpaid dividends.  In the event the Corporation 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 Series A
Preferred  Stock  were  entitled  immediately  prior  to such  event  under  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) If the assets of the  Corporation  legally  available  for
distribution  to the  holders  of  shares  of  Series  A  Preferred  Stock  upon
liquidation,  dissolution or winding up of the Corporation  are  insufficient to
pay the full  preferential  amount set forth in the first  sentence of paragraph
(A) above,  then the entire  assets of the  Corporation  legally  available  for
distribution  to the  holders of Series A Preferred  Stock shall be  distributed
among such holders in proportion to the shares of Series A Preferred  Stock then
held by them.

                  (C) The  foregoing  rights upon  liquidation,  dissolution  or
winding up provided to the holders of Series A Preferred  Stock shall be subject
to the rights of the  holders  of any other  series of  Preferred  Stock (or any
other stock)  ranking  prior and  superior to the Series A Preferred  Stock upon
liquidation, dissolution or winding up.

         Section 7.  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  other  property,  then in any such case each share of
Series A  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 200  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  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 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.

                                       4


         Section 8. No Redemption.  The shares of Series A Preferred Stock shall
not be redeemable.

         3.  The  authorized   number  of  shares  of  Preferred  Stock  of  the
corporation is 5,000,000 of which none have been issued. The number of shares of
Preferred Stock to constitute the Series A Preferred Stock is 500,000 shares, no
shares of which series have been issued.

         We further declare under penalty of perjury under the laws of the State
of California  that the matters set forth in this  Certificate of  Determination
are true and correct of our own knowledge.

         IN WITNESS WHEREOF, the undersigned have executed this certificate this
___ day of September, 1998.
