         THE UNDERSIGNED,  being a duly authorized officer of U.S. Home & Garden

         3. That the  Certificate of  Incorporation  of the Corporation has been
further  amended as follows  by  inserting  a new  Article  ELEVENTH  reading as
follows:

                  "ELEVENTH:  1. The number of directors comprising the Board of
         Directors  shall be such  number as may be from  time to time  fixed by
         resolution of the Board of Directors.  Commencing with the first annual
         meeting  of  stockholders  held  after  the  adoption  of this  Article
         Eleventh,  the directors shall be classified in respect to the time for
         which they shall  severally  hold office,  by dividing  them into three
         classes. The number of directors in each class shall be as nearly equal
         as possible.  At each annual election,  any vacancy in any class may be
         filled and the  successors  to the  directors  of the class whose terms
         shall  expire in that year shall be elected to hold office for the term
         of three years,  and the term of office of one class of directors shall
         expire in each year. In the event the number of directors is increased,
         election  may be made to a class of  directors  with terms  expiring in
         three years or less in order to maintain proportionate equality between
         the classes.

                  2. The directors  shall be elected by the holders of shares of
         stock of the Corporation entitled to vote on the election of directors,
         and directors shall be elected by a plurality vote. The directors shall
         be divided  into  three  classes,  designated  as Class I, Class II and
         Class  III  as  set  forth  in  Section  1 of  this  Article  ELEVENTH.
         Commencing with the first annual meeting of stockholders held after the
         adoption of this Article  ELEVENTH,  the Class I directors  shall serve
         until  the  following  annual  meeting  of  stockholders,  the Class II
         directors until the next successive annual meeting of stockholders, and
         the Class III directors until the third annual meeting of stockholders,
         in each case, until their  successor(s) are duly elected and qualified.
         At each annual meeting of stockholders commencing with the first annual
         meeting  following  the adoption of this Article  ELEVENTH  each of the
         successors  to the Directors of the Class whose term shall have expired
         that year  shall be elected  for a  three-year  term.  If the number of
         directors  is changed,  any increase or decrease  shall be  apportioned
         among the classes so as to  maintain  the number of  directors  in each
         class as nearly equal as possible,  and any additional  director of any
         class  elected to fill a vacancy  resulting  from an  increase  in such
         class  shall  hold  office  for a term  that  shall  coincide  with the
         remaining  term of that  class,  but in no case will a decrease  in the
         number of  directors  shorten  the term of any  incumbent  director.  A
         director  shall hold  office  until the annual  meeting for the year in
         which his term  expires  and until the  successor  shall be elected and
         shall   qualify,   subject,   however  to  prior  death,   resignation,
         retirement,  disqualification  or  removal  from  office.  Any  vacancy
         occurring in the Board of Directors,  including any vacancy  created by
         reason of an increase in the number of  directors,  shall be filled for
         the  unexpired  term  by  the  concurring  vote  of a  majority  of the
         directors then in office,  whether or not a quorum, and any director so
         chosen  shall  hold  office for the  remainder  of the full term of the
         class of  directors  in which the new  directorship  was created or the
         vacancy  occurred and until such  director's  successor shall have been
         elected and qualified."

                  4. That such  amendments  have been duly adopted in accordance
         with the  provisions  of the  General  Corporation  Law of the State of
         Delaware  by the  affinuative  vote of the holders of a majority of the
         stock entitled to vote at a meeting of stockholders.
