transactions executed on the New York Stock Exchange, the Boston Stock

pledgees or agents) pursuant to unsolicited orders or offers to buy, (b) in 
negotiated transactions, or (c) through other means.  The Shares may be sold 
from time to time in one or more transactions at market prices prevailing at 
the time of sale, or a fixed offering price, which may be changed, or at 
varying prices determined at the time of sale or at negotiated prices.  Such 
prices will be determined by a Selling Shareholder or by agreement between a 
Selling Shareholder and his underwriters, dealers, brokers or agents.  The 
Shares may also be offered in one or more underwritten offerings.  The 
underwriters in an underwritten offering, if any, and the terms and conditions 
of any such offering will be described in a supplement to this Prospectus.
    

   
        In connection with the distribution of the Shares, the Selling 
Shareholders may enter into hedging or other option transactions with 
broker-dealers in connection with which, among other things, such 
broker-dealers may engage in short sales of the Shares pursuant to this 
Prospectus in the course of hedging the positions they assume with the Selling
Shareholders.  The Selling Shareholders may also sell Shares short pursuant
to this Prospectus and deliver the Shares to close out such short positions.

to this Prospectus.
    

           
        Any underwriters, dealers, brokers or agents participating in the 
distribution of the Shares may receive compensation in the form of 
underwriting discounts, concessions, commissions or fees from a Selling 
Shareholder and/or purchasers of Shares, for whom they may act.  Such 
discounts, concessions, commissions or fees will not exceed those customary
for the type of transactions involved.  In addition, a Selling Shareholder 
and any such underwriters, dealers, brokers or agents that participate in the 
distribution of Shares may be deemed to be underwriters under the Securities 
Act, and any profits on the sale of Shares by them and any discounts, 
commissions or concessions received by any of such persons may be deemed to be 
underwriting discounts and commissions under the Securities Act.  Those who 
act as underwriter, broker, dealer or agent in connection with the sale of the 
Shares will be selected by a Selling Shareholder and may have other business 
relationships with the Company and its subsidiaries or affiliates in the 
ordinary course of business.

underwriter, if any, against certain liabilities, including liabilities under

Item 15.  Indemnification of Directors and Officers

    Section 67 of Chapter 156B of the Massachusetts General Laws provides
that a corporation may indemnify its directors and officers to the extent
specified in or authorized by (i) the articles of organization, (ii) a
bylaw adopted by the stockholders, or (iii) a vote adopted by the holders
of a majority of the shares of stock entitled to vote on the election of
directors.  Such Section further provides, however, that no indemnification
may be provided with respect to any matter as to which the officer or
director is adjudicated not to have acted in good faith in the reasonable
belief that his action was in the best interest of the corporation or, to
the extent such matter relates to service with respect to an employee
benefit plan, in the best interest of the participants or beneficiaries of
such employee benefit plan.

    Article V, Section 2 of the Bylaws of the Company provides that every
person who is, or has been, a director or officer of the Company is
entitled to indemnification by the Company to the fullest extent permitted
by law against liability and against all expenses reasonably incurred or
paid by him in connection with any claim, action, suit or proceeding in
which he becomes involved as a party or otherwise by virtue of his being or
having been a director or officer and against amounts paid or incurred by
him in the settlement thereof.

     No indemnification is provided under the Bylaws to a director or
officer with respect to any matter as to which he has been finally
adjudicated not to have acted in good faith in the reasonable belief that
his action was in the best interests of the corporation.  Nor is
indemnification provided to a director or officer in the event of a
settlement involving a payment by the officer or director unless there has
been a determination that such director or officer is entitled to
indemnification under Article V, Section 2 of the Bylaws by one of the
following:  (i) the court or other body approving the settlement; (ii) vote
of stockholders of the Company; (iii) vote of two-thirds of those directors
of the Company who are not themselves involved in the claim, action, suit
or proceeding, provided that a majority of the directors consists of
members not so involved; or (iv) written opinion of independent counsel.

    The Company's Bylaws authorize the Company to obtain insurance to
cover its indemnification obligations.  The Company currently maintains
director and officer liability insurance for the benefit of its directors
and certain of its officers.

     Article 6 of the Articles of Organization of the Company, as amended,
provides that, to the fullest extent permitted by the Massachusetts General
Laws, no director of the Company shall be personally liable to the Company
or its stockholders for monetary damages for breach of fiduciary duty as a
director.

Item 17.  Undertakings

     The undersigned registrant hereby undertakes:

          (1)  To file, during any period in which offers or sales are
     being made, a post-effective amendment to this Registration Statement:

               (i)  To include any material information with respect to the
          plan of distribution not previously disclosed in the Registration
          Statement or any material change to such information in the
          Registration Statement.

          (2)  That, for the purpose of determining any liability under the
     Securities Act of 1933, each such post-effective amendment shall be
     deemed to be a new registration statement relating to the securities
     offered therein, and the offering of such securities at that time
     shall be deemed to be the initial bona fide offering thereof.

          (3)  To remove from registration by means of a post-effective
     amendment any of the securities being registered which remain unsold
     at the termination of the offering.

     The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of
the registrant's annual report pursuant to section 13(a) or section 15(d)
of the Securities Exchange Act of 1934 (and, where applicable, each filing
of an employee benefit plan's annual report pursuant to Section 15(d) of
the Securities Exchange Act of 1934) that is incorporated by reference in
the Registration Statement shall be deemed to be a new registration
statement relating to the securities offered therein, and the offering of
such securities at that time shall be deemed to be the initial bona fide
offering thereof.

     The undersigned registrant hereby undertakes that:

     (1)  For purposes of determining any liability under the Securities
Act of 1933, the information omitted from the form of prospectus filed as
part of this Registration Statement in reliance upon Rule 430A and
contained in a form of prospectus filed by the registrant pursuant to
Rule 424(b)(1) or (4), or 497(h) under the Securities Act shall be deemed
to be part of this Registration Statement as of the time it was declared
effective.

     (2)  For the purpose of determining any liability under the Securities
Act of 1933, each post-effective amendment that contains a form of
prospectus shall be deemed to be a new registration statement relating to
the securities offered therein, and the offering of such securities at that
time shall be deemed to be the initial bona fide offering thereof.

     Insofar as indemnification of liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons
of the registrant pursuant to the provisions described under Item 15 above,
or otherwise, the registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public
policy as expressed in the Act and is, therefore, unenforceable.  In the
event that a claim for indemnification against such liabilities (other
than the payment by the registrant of expenses incurred or paid by a
director, officer or controlling person of the registrant in the successful
defense of any action, suit or proceeding) is asserted by such director,
officer or controlling person in connection with any of the securities
being registered, the registrant will, unless in the opinion of its counsel
the matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it
is against public policy as expressed in the Act and will be governed by
the final adjudication of such issue.
                                        
                                        
                                        
                                        
                                        
                                        
                                        
                                        
                                        
                                        
                                        
                                        
                                        
                                        
                                        
                                        
                                        
                                        
                                        
                                        
                                        
                                        
                                        SIGNATURES
