                  SIXTH:  The corporation is to have perpetual existence.

                  SEVENTH:  Whenever a  compromise  or  arrangement  is proposed
between this  corporation  and its creditors or any class of them and/or between
this corporation and







its  stockholders  or any  class of them,  any court of  equitable  jurisdiction
within the State of Delaware  may, on the  application  in a summary way of this
corporation or of any creditor or stockholder  thereof or on the  application of
any receiver or receivers  appointed for this  corporation  under section 291 of
Title 8 of the Delaware Code or on the application of trustees in dissolution or

creditors,  and/or  of  the  stockholders  or  class  of  stockholders  of  this
corporation, as the case may be, to be summoned in such manner as the said court
directs.  If a majority  in number  representing  three-fourths  in value of the
creditors  or  class  of  creditors,  and/or  of the  stockholders  or  class of
stockholders of this corporation, as the case may be, agree to any compromise or
arrangement and to any reorganization of this corporation as consequence of such
compromise  or  arrangement,  the said  compromise or  arrangement  and the said
reorganization  shall, if sanctioned by the court to which the said  application
has been made, be binding on all of the creditors or class of creditors,  and/or
on all the stockholders or class of stockholders,  of this  corporation,  as the
case may be, and also on this corporation.

                  EIGHTH: 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  and of its  directors  and of its
stockholders or any class thereof, as the case may be, it is further provided:

                  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 by, or in the manner provided in, the ByLaws.
         The phrase  "whole  Board" and the phrase  "total  number of directors"
         shall be deemed to have the same  meaning,  to wit, the total number of
         directors which the corporation  would have if there were no vacancies.
         No election of directors need be by written ballot.

                  2. After the original or other By-Laws of the corporation have
         been adopted,  amended, or repealed,  as the case may be, in accordance
         with the  provisions of Section 109 of the General  Corporation  Law of
         the State of  Delaware,  and,  after the  corporation  has received any
         payment for any of its stock,  the power to adopt, amend, or repeal the
         By-Laws of the  corporation  may be exercised by the Board of Directors
         of the  corporation;  provided,  however,  that any  provision  for the
         classification  of directors of the  corporation  for  staggered  terms
         pursuant  to the  provisions  of  subsection  (d) of Section 141 of the
         General  Corporation Law of the State of Delaware shall be set forth in
         an initial By-Law or in a By-Law adopted by the  stockholders  entitled
         to vote of the corporation  unless  provisions for such  classification
         shall be set forth in this certificate of incorporation.


                                        2





                  3. Whenever the corporation  shall be authorized to issue only
         one class of stock,  each  outstanding  share shall  entitle the holder
         thereof  to  notice  of,  and the  right to vote  at,  any  meeting  of
         stockholders.  Whenever the  corporation  shall be  authorized to issue
         more  than one  class of stock,  no  outstanding  share of any class of
         stock  which  is  denied  voting  power  under  the  provisions  of the
         certificate  of  incorporation  shall entitle the holder thereof to the
         right to vote at any meeting of  stockholders  except as the provisions
         of  paragraph  (2) of  subsection  (b) of  section  242 of the  General
         Corporation  Law of the  State of  Delaware  shall  otherwise  require;
         provided,  that no share of any such class  which is  otherwise  denied
         voting power shall entitle the holder thereof to vote upon the increase
         or decrease in the number of authorized shares of said class.

                  NINTH:  The  personal   liability  of  the  directors  of  the
corporation  is  hereby  eliminated  to  the  fullest  extent  permitted  by the
provisions  of  paragraph  (7) of  subsection  (b) of Section 102 of the General
Corporation  Law of the  State  of  Delaware,  as the same  may be  amended  and
supplemented.

                  TENTH: The corporation  shall, to the fullest extent permitted
by the provisions of Section 145 of the General  Corporation Law of the State of
Delaware,  as the same may be amended and  supplemented,  indemnify  any and all
persons  whom it shall  have power to  indemnify  under  said  section  from and
against any and all of the expenses, liabilities or other matters referred to in
or covered by said section,  and the  indemnification  provided for herein shall
not be deemed  exclusive of any other rights to which those  indemnified  may be
entitled under any By-Law,  agreement,  vote of  stockholders  or  disinterested
directors or  otherwise,  both as to action in his  official  capacity and as to
action in another capacity while holding such office, and shall continue as to a
person who has ceased to be a  director,  officer,  employee  or agent and shall
inure to the  benefit  of the  heirs,  executors  and  administrators  of such a
person.

                  ELEVENTH:  From  time to time  any of the  provisions  of this
certificate  of  incorporation  may be amended,  altered or repealed,  and other
provisions  authorized by the laws of the State of Delaware at the time in force
may be added or inserted in the manner and at the time  prescribed by said laws.
and all rights at any time conferred upon the stockholders of the corporation by
this certificate of incorporation  are granted subject to the provisions of this
Article ELEVENTH.
