shares until the shares have been transferred into the name of the pledgee,  and
thereafter the pledgee shall be entitled to vote the shares so transferred.

                                   Article VI
                 Certificates for Shares and Their Transfer

      Section 6.1. Certificates for Shares.  Certificates representing shares of
the  Corporation  shall be in such  form as may be  determined  by the  Board of
Directors.  Such  certificates  shall be  signed  by the  President,  and by the
Treasurer or such other  officers as are  authorized  by the Board of Directors,
and  shall  be  sealed  with  the  Seal of the  Corporation.  The  seal may be a
facsimile.  If a stock  certificate  is  countersigned  (i). by a transfer agent
other than the  Corporation or its employee,  or (ii) by a registrar  other than
the Corporation or its employee, any other signature on the certificate may be a
facsimile.  In case any officer,  transfer agent, or registrar who has signed or
whose facsimile  signature has been placed upon a certificate  shall have ceased
to be such officer,  transfer  agent,  or registrar  before such  certificate is
issued,  it may be issued by the Corporation  with the same effect as if he were
such officer, transfer agent or registrar at the date of issue. All certificates
for shares and any stock rights,  or options or warrants shall be  consecutively
numbered  or  otherwise  identified.  The name of the person to whom the shares,
rights,  warrants or options  represented thereby are issued, with the number of
shares  or  rights  and date of  issue,  shall be  entered  on the  books of the
Corporation.  All certificates surrendered to the Corporation for transfer shall
be canceled and no new certificates shall be issued until the former certificate
for a like number of shares shall have been  surrendered  and  canceled,  except
that in case of a lost,  destroyed,  or mutilated  certificate  a new one may be
issued therefor upon such terms and indemnity to the Corporation as the Board of
Directors  may  prescribe.  In most cases the sworn  affidavit of the owner that
certificates  have been  lost,  destroyed,  or  mutilated,  the  provision  of a
replacement bond satisfactory to Corporation counsel, and a commitment to return
the prior shares to the Corporation should they be found with a personal promise
to indemnify the Corporation from any and all losses arising from or as a result
of the replacement should be satisfactory.

      Section 6.2.  Transfer of Shares.  Transfers of shares of the  Corporation
shall be made  only on the  books of the  Corporation  by the  holder  of record
thereof or by his legal  representative,  who shall furnish  proper  evidence of
authority  to  transfer,  or by his attorney  thereunto  authorized  by power of
attorney duly executed and filed with the Secretary of the  Corporation,  and on
surrender for  cancellation of the  certificate  for such shares.  The person in
whose  name  shares  stand on the books of the  Corporation  shall be deemed the
owner thereof for all purposes as regards the Corporation.





                                   Article VII

corporate seal which shall be in the form of a circle and shall have
inscribed thereon the name of the Corporation.

                                   Article IX
                                Waiver of Notice

      Section 9.1 Waiver of Notice.  Whenever any notice whatever is required to
be given under the  provisions  of these Bylaws or under the  provisions  of the
Certificate of Incorporation or under the provisions of the General  Corporation
Law of  Delaware,  waiver  thereof  in  writing  signed by the person or persons
entitled to such notice,  whether before or after the time stated therein, shall
be deemed equivalent to the giving of such notice. Attendance of any person at a
meeting  for  which  any  notice  whatever  is  required  to be given  under the
provisions of these Bylaws,  the  Certificate  of  Incorporation  or the General
Corporation Law of Delaware shall constitute a waiver of notice of such meeting,
except  when the person  attends for the express  purpose of  objecting,  at the
beginning of the meeting, to the transaction of any business because the meeting
is not lawfully called or convened.

                                    Article X
                                   Amendments

      Section  10.1.  Amendments.  These  Bylaws may be altered,  amended,
or  repealed  and new Bylaws may be adopted at any meeting of the Board of
Directors  of the  Corporation  by the  affirmative  vote of a majority of
the members of the Board.
