                           PLAN OF DISTRIBUTION

    The Shares offered hereby may be sold from time to time by the Selling
Shareholders acting as principals for their own account.  The Company is
responsible for all expenses incurred in connection with the registration
of the Shares.  The Selling Shareholders will pay brokerage commissions or
other charges and expenses incurred in the sale of the Shares.  The Company
has agreed to indemnify the Selling Shareholders against certain
liabilities, including liabilities under the Securities Act.

    The distribution of the Shares by the Selling Shareholders is not
currently subject to any underwriting agreement.  The Shares covered by
this Prospectus may be sold by the Selling Shareholders or by pledgees,
donees, transferees or other successors in interest from time to time, and
the Company believes that it is the intention of the Selling Shareholders
to complete such sales within ninety (90) days of the date of this
Prospectus.  Such sales may be made at fixed prices that may be changed, at
market prices prevailing at the time of sale, at prices related to such
prevailing market prices, or at negotiated prices.  Such sales may be
effected in the over-the-counter market, on the New York Stock Exchange or
on any other exchange on which the Shares may then be listed.  The Shares
may be sold by one or more of the following:  (a) one or more block trades
in which a broker or dealer so engaged will attempt to sell all or a
portion of the Shares held by the Selling Shareholders as agent but may
position and resell a portion of the block as principal to facilitate the
transaction; (b) purchases by a broker or dealer as principal and resale by
such broker or dealer for its account pursuant to this Prospectus; and (c)
ordinary brokerage transactions and transactions in which the broker
solicits purchasers.  The Selling Shareholders will effect such
transactions by selling Shares through broker-dealers, and such broker-
dealers will receive compensation in negotiated amounts in the form of
discounts, concessions, commissions or fees which will be paid by the
Selling Shareholders.  Such brokers or dealers and the Selling Shareholders
may be deemed to be "underwriters" within the meaning of the Securities
Act, in connection with such sales, and any commissions received by such
broker-dealers may be deemed to be underwriting compensation.  One or more
Selling Shareholders may also transfer some of their Shares by way of gift
pursuant to this Prospectus.

    The Company will provide a copy of this Prospectus to the New York
Stock Exchange pursuant to Rule 153 under the Securities Act.

    State Street Bank & Trust Company, c/o Boston Equiserve, 150 Royall
Street, Canton, Massachusetts 02021, is the transfer agent for the
Company's Common Stock.

Item 15. Indemnification of Directors and Officers

    The Company is permitted by Massachusetts law and required by its By-
laws to indemnify any director or officer or former director or officer
against all expenses and liabilities reasonably incurred by him in
connection with any legal action in which such person is involved by reason
of his position with the Company unless he shall have been finally
adjudicated in any action, suit or proceeding not to have acted in good
faith in the reasonable belief that his action was in the best interests of
the Company.  Such idemnification shall include payment by the Company of
expenses incurred in defending a civil or criminal action or proceeding in
advance of the final disposition of such action or defending a civil or
criminal action or proceeding, upon the Company's receipt of the
undertaking of the person indemnified to repay such payment if such person
shall be adjudicated not entitled to such indemnification.

    Directors and officers are also insured up to an aggregate amount of
$10,000,000 under a Directors' and Officers' Liability and Company
Reimbursement Policy.

    The Company's Restated Articles of Organization include a provision
limiting the personal liability of directors of the Company to its
stockholders for monetary damages for breaches of their fiduciary duty to
the extent permitted by the Massachusetts Business Corporation Law.

Item 17. Undertakings.

    (a)  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 prospectus required by Section
10(a)(3) of the Securities Act of 1933;

                (ii)      To reflect in the prospectus any facts or events
arising after the effective date of the registration statement (or the most
recent post-effective amendment thereof) which, individually or in the
aggregate, represent a fundamental change in the information set forth in
the registration statement.  Notwithstanding the foregoing, any increase or
decrease in volume of securities offered (if the total dollar value of
securities offered would not exceed that which was registered) and any
deviation from the low or high end of the estimated maximum offering range
may be reflected in the form of prospectus filed with the Commission
pursuant to Rule 424(b) if, in the aggregate, the changes in volume and
price represent no more than a 20% change in the maximum aggregate offering
price set forth in the "Calculation of Registration Fee" table in the
effective registration statement;



                               II-2
/12



                 (iii) 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; provided, however, that paragraphs
(a)(1)(i) and (a)(1)(ii) above do not apply if the information
required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed by the registrant
pursuant to Section 13 or Section 15(d) of the Securities Exchange
Act of 1934 that are incorporated by reference 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.

      (b)    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 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.

      (c)    Insofar as indemnification for liabilities arising
under the Securities Act of 1933 may be permitted to directors,
officers and controlling persons of the registrant pursuant to the
foregoing provisions, 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 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 Securities Act of 1993 and will be governed by the final
adjudication of such issue.
