                             CONTINUATION SHEET 6A


     ONE:  All corporate powers of the Corporation shall be exercised by the
Board of Directors except as otherwise provided by law.  In furtherance and not
in limitation of the powers conferred by statute, the Board of Directors is
expressly authorized to make, amend or repeal the By-Laws of the Corporation in
whole or in part, except with respect to any provision thereof which by law or
the By-Laws requires action by the stockholders, and subject to the power of the
stockholders to amend or repeal any By-Law adopted by the Board of Directors.

     TWO:  Meetings of the stockholders of the Corporation may be held anywhere
within the United States.

     THREE:  The Corporation may be a partner in any business enterprise which
it would have power to conduct by itself.

     FOUR:  In the absence of fraud, no contract or other transaction of the
Corporation shall be affected or invalidated by the fact that any of the
directors of the Corporation are in any way interested in or connected with any
other party to such contract or transaction or are themselves parties to such
contract or transaction, provided that the interest in any such contract or
transaction of any such director shall at the time be fully disclosed or
otherwise known to the Board of Directors.  Any director of the Corporation may
be counted in determining the existence of a quorum at any meeting of the Board
of Directors which shall authorize such contract or transaction and may vote and
act upon any matter, contract or transaction between the Corporation and any
other person without regard to the fact that he is also a stockholder, director
or officer of, or has any interest in, such other person with the same force and
effect as if he were not such stockholder, director or officer or not so
interested.  Any contract or other transaction of the Corporation or of the
Board of Directors or of any committee thereof which shall be ratified by a
majority of the holders of the issued and outstanding stock entitled to vote at
any annual meeting or any special meeting called for that purpose shall be as
valid and as binding as though ratified by every stockholder of the Corp
oration; provided, however, that any failure of the stockholders to approve or
ratify such contract or other transaction, when and if submitted, shall not be
deemed in any way to render the same invalid or deprive the directors and
officers of their right to proceed with such contract or other transaction.

 
     Article Six of the Corporation's Articles of Organization is hereby
     amended by adding thereto the provisions contained in Continuation
     Sheet 6A annexed hereto. No change is made to the other provisions of 
     said Article Six or of the Articles of Organization












The foregoing amendment(s) will become effective when these Articles of 
Amendment are filed in accordance with General Laws, Chapter 156B, Section 6 
unless these articles specify, in accordance with the vote adopting the 
amendment, a later effective date not more than thirty days after such filing, 
in which event the amendment will become effective on such later date.

Later effective date:______________________.
