                                      -1-

                                      109


            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
ss. 291 of Title 8 of the  Delaware  Code or on the  application  of trustees in
dissolution or of any receiver or receivers appointed for this corporation under
ss. 279 of Title 8 of the  Delaware  Code order a meeting  of the  creditors  or
class of 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

has been made, be binding on all 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 Bylaws of the  corporation  have been
      adopted,  amended, or repealed, as the case may be, in accordance with the
      provisions  of ss.  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  Bylaws 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 ss. 141 of the General  Corporation  Law of the State of
      Delaware  shall be set forth in an initial  Bylaw or in a Bylaw 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-

                                      110


            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 ss. 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 ss. 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 ss. 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  Bylaw,  agreement,  vote of  stockholders  or  disinterested  directors  or
otherwise, both as to action in such person's 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 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.
