                                   ARTICLE VII

     No  director  of  this  Corporation  shall  be  personally  liable  to  the
Corporation or its  shareholders for monetary damages for breach of duty by such
director  as a  director  to  the  extent  that  damages  are in  excess  of the
compensation  received by such director for serving the  Corporation  during the
year of the violation;  provided, however, that this article shall not eliminate
or limit the liability of a director to the extent provided by applicable law if
such  breach  (i)  involved  a  knowing  and  culpable  violation  of law by the
director,  (ii)  enabled  the  director  or an  associate,  as  defined  in  the
Connecticut  Stock  Corporation Act,  section 33-374d,  subd. (3), to receive an
improper  personal  economic  gain,  (iii)  showed  a lack of good  faith  and a
conscious  disregard  for the  duty of the  director  to the  Corporation  under
circumstances  in which  the  director  was  aware  that his or her  conduct  or
omission  created an  unjustifiable  risk of serious injury to the  Corporation,
(iv) constituted a sustained and unexcused  pattern of inattention that amounted
to an  abdication  of the  director's  duty to the  Corporation,  or (v) created
liability under the  Connecticut  Stock  Corporation  Act,  section  33-321.  No
amendment to or repeal of this article  shall apply to or have any effect on the
liability or alleged  liability of any director of the  Corporation  for or with
respect  to any  acts or  omissions  of such  director  occurring  prior to such
amendment or repeal."
