         FIRST: The name of the corporation is Base Ten Systems, Inc.

         SECOND:  Article  6(a)  of  the  Certificate  of  Incorporation  of the
corporation is amended to read in its entirety, as follows:

         "(a) This corporation is authorized to issue three classes of shares of
         stock  to be  designated  "Class  A  Common,"  "Class  B  Common,"  and
         "Preferred."  The  total  number of shares  that  this  corporation  is
         authorized  to issue is  42,999,500  and the aggregate par value of all
         such shares is $42,999,500.  Forty million of the shares shall be Class
         A Common shares of a par value of $1.00 each. Two million of the shares
         shall be Class B  Common  shares  of a par  value of $1.00  each.  Nine
         hundred  ninety-nine  thousand  five  hundred  of the  shares  shall be
         Preferred shares of a par value of $1.00 each."

         THIRD:  Article  6(c)  of  the  Certificate  of  Incorporation  of  the
corporation is amended to read in its entirety, as follows:

         "(c)  Except  as set  forth in this  Article  6(c),  the Class A Common
         shares and Class B Common shares shall be identical in all respects and
         shall have equal rights and privileges.

         A.  Dividends and Distributions

         (1) Subject to rights of the Preferred  shares granted pursuant to this
         Certificate  of  Incorporation,  the  corporation  may pay dividends to
         holders of Class A Common shares and Class B Common shares, as a single
         class.  If a dividend is paid, the same amount shall be paid in respect
         of each outstanding Class A or Class B Common share.

         (2) If at any  time a  distribution  is to be  paid in  Class A  Common
         shares or Class B Common shares (a "share distribution"),  only Class A
         Common  shares may be paid to holders of Class A Common shares and only
         Class B Common shares may be paid to holders of Class B Common  shares.
         Whenever a share  distribution is paid, the same number of shares shall
         be paid in respect of each outstanding Class A or Class B Common share.
         The corporation shall not combine or subdivide shares of either of such
         classes without at the same time making a proportionate  combination or
         subdivision of shares of the other of such classes.

         B.  Voting.

         (1) The  holders  of  Class A and  Class B Common  shares  shall in all
         matters vote together as a single class  (subject to voting rights that
         may be granted to any holders of Preferred  shares  pursuant to Article
         6(c) of this  Certificate  of  Incorporation),  the  holders of Class A
         Common  shares and Class B Common  shares are  entitled to one vote for
         each share. The directors of the corporation  elected by the holders of
         Class A Common shares and by the holders of Class B Common shares shall
         be  considered  as having been elected by the Class A Common shares and
         the  Class  B  Common  shares   voting   together  as  a  single  class
         notwithstanding  that prior to the  effective  date of the Amendment to
         the Certificate of Incorporation inserting this sentence, the directors
         may have been elected by a separate class.

         (2) The  holders of Class A Common  shares  and Class B Common  shares,
         voting as a single class, shall be entitled to vote as a separate class
         on the removal, for cause, of any director (subject to voting rights of
         Preferred  shares granted  pursuant to Article 6(c) of this Certificate
         of Incorporation).

         (3) Any vacancy in the office of a director  may be filled by a vote of
         holders of shares  entitled to vote  (subject  to voting  rights of the
         Preferred  shares granted  pursuant to Article 6(c) of this Certificate
         of  Incorporation)  and,  in the  absence of a  stockholder  vote,  the
         vacancy  may be filled by the  remaining  directors  as provided in the
         By-laws.  Any  director  elected  by the Board of  Directors  to fill a
         vacancy shall serve the same remaining term as that of his  predecessor
         and until his or her  successor has been chosen and has  qualified.  If
         permitted  by the  By-laws,  the Board of  Directors  may  increase the
         number of directors  and any  vacancies so created may be filled by the
         Board of Directors.



         (4) The  holders of the Class A Common  shares  and the  holders of the
         Class B Common shares shall be entitled to vote as separate  classes on
         such other  matters as may be  required by law or this  Certificate  of
         Incorporation  to be  submitted  to such  holders  voting  as  separate
         classes.

         C.  Conversion.  Each holder of record of Class B Common  shares may at
         any time or from time to time, in such holder's sole  discretion and at
         such holder's option,  convert any whole number of all of such holder's
         Class B Common shares into fully paid and non-assessable Class A Common
         shares at the rate (subject to adjustment as  hereinafter  provided) of
         one and  one-half  Class A Common  share for each Class B Common  share
         surrendered for conversion.  Any such conversion may be effected by any
         holder of Class B Common shares surrendering such holder's  certificate
         or  certificates  for the Class B Common shares to be  converted,  duly
         endorsed,  at the office of the  corporation  or any transfer agent for
         the  Class B Common  shares,  together  with a  written  notice  to the
         corporation  at such office that such holder elects to convert all or a
         specified number of Class B Common shares and stating the name or names
         in which such holder desires the certificate or  certificates  for such
         Class  A  Common  shares  to  be  issued.   Promptly  thereafter,   the
         corporation  shall issue and  deliver to such  holder or such  holder's
         nominee or nominees,  a certificate or  certificates  for the number of
         Class A Common  shares  to which  such  holder  shall  be  entitled  as
         aforesaid.  Such  conversion  shall be  deemed to have been made at the
         close of  business  on the date of such  surrender  and the  person  or
         persons  entitled to receive the Class A Common shares issuable on such
         conversion  shall be treated for all  purposes as the record  holder or
         holders of such Class A Common shares on that date.

         The number of Class A Common shares into which the Common shares may be
         converted shall be subject to adjustment from time to time in the event
         of any  capital  reorganization,  reclassification  of the stock of the
         corporation,  consolidation  or merger of the corporation  with or into
         another  corporation or sale or conveyance of all or substantially  all
         of the assets of the corporation to another corporation or other entity
         or person.  Each Class B Common share shall  thereafter be  convertible
         into such kind and amount of securities  or other  assets,  or both, as
         are  issuable  or  distributable  in  respect  of the number of Class A
         Common  shares  into  which each  Class B Common  share is  convertible
         immediately   prior   to   such    reorganization,    reclassification,
         consolidation, merger sale or conveyance. In any such case, appropriate
         adjustments  shall be made by the Board of Directors of the corporation
         in the  application of the provisions  herein set forth with respect to
         the rights and  interests  thereafter  of the holders of Class B Common
         shares,  to the end that the  provisions  set forth  herein  (including
         provisions for adjustment of the conversion rate) shall thereinafter be
         applicable,  as  nearly  as  reasonably  may  be,  in  relation  to any
         securities or other assets thereafter  deliverable on conversion of the
         Class B Common shares.

         No fraction of a Class A Common share shall be issued on  conversion of
         any Class B Common share but, in lieu thereof,  the  corporation  shall
         pay in cash  therefor  the pro  rata  fair  market  value  of any  such
         fraction.  Such  fair  market  value  shall  be  based,  in the case of
         publicly traded securities,  on the last sale price for such securities
         on the business day next prior to the date such fair market value is to
         be  determined  (or,  in the  event  no sale is made on that  day,  the
         average  of the  closing  bid and  asked  prices  for  that  day on the
         principal  stock exchange on which Class A Common shares are traded or,
         if the  Class A Common  shares  are not  then  listed  on any  national
         securities  exchange,  the average of the closing bid and asked  prices
         for that day  quoted  by the  NASDAQ  System)  or, in the case of other
         property,  the fair market value on such day  determined by a qualified
         independent  appraiser expert in evaluating such property and appointed
         by the Board of Directors of the corporation. Any such determination of
         fair market value shall be final and binding on the  corporation and on
         each holder of Class B Common shares or Class A Common shares.

         The  corporation  shall at all times reserve and keep  available out of
         the  authorized  and  unissued  Class A Common  shares,  solely for the
         purpose of effecting the conversion of the  outstanding  Class B Common
         shares, such number of Class A Common shares as shall from time to time
         be  sufficient  to effect the  conversion  of all  outstanding  Class B
         Common  shares  and if,  at any time,  the  number  of  authorized  and
         unissued  Class A Common  shares  shall  not be  sufficient  to  effect
         conversion  of  the  then  outstanding  Class  B  Common  shares,   the
         corporation  shall take such  corporate  action as may be  necessary to
         increase the number of authorized and unissued Class A Common shares to
         such number as shall be sufficient for such purposes.

         The  Preferred  shares  may be issued  from time to time in one or more
         series. The Board of Directors is hereby authorized to fix or alter the
         designations,  preferences,  and relative,  participating,  optional or
         other special rights, and qualifications,  limitations or restrictions,
         of  such  Preferred  shares,   including  without   limitation  of  the
         generality  of  the  foregoing,   dividend   rights,   dividend  rates,
         conversion  rights,  voting  rights,  rights  and  terms of  redemption
         (including sinking fund provisions), the redemption price or prices and
         liquidation  preferences  of any wholly  unissued  series of  Preferred
         shares,  and the number of shares  constituting any such series and the
         designation  thereof,  or any of them;  and to increase or decrease the
         number 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  which they had prior to the  adoption  of the
         resolution originally fixing the number of shares of such series."

         FOURTH:   Article  8  of  the  Certificate  of   Incorporation  of  the
corporation is amended to read in its entirety, as follows:

         "Any merger, consolidation of the corporation, or sale, lease, exchange
         or other  disposition of all, or  substantially  all, the assets of the
         corporation,  if not in the usual and regular course of its business as
         conducted by the  corporation,  shall require the  affirmative  vote of
         seventy-five percent of the votes cast by holders of shares entitled to
         vote thereon."
