ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Section 67 of chapter 156B of the Massachusetts Business Corporation Law
grants the Company the power to indemnify any director, officer, employee or
agent, to whatever extent permitted by the Company's Articles of Organization,
Bylaws or a vote adopted by the holders of a majority of the shares entitled to
vote thereon, if such indemnitee acted (a) in good faith in the reasonable
belief that his action was in the best interests of the corporation or (b) to
the extent that the matter for which indemnification is sought relates to
service with respect to an employee benefit plan, in the best interests of the
participants or beneficiaries of such employee benefit plan. Such
indemnification may 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 proceeding, upon receipt of an undertaking by the
person indemnified to repay such payment if he shall be adjudicated to be not
entitled to indemnification under the statute.

     Article X of the Company's Bylaws provides that the Company shall, to the
extent legally permissible, indemnify each person who may serve or who has
served at any time as a director or officer of the Company or of any of its
subsidiaries, or who at the request of the Company may serve or at any time has
served as a director, officer or trustee of, or in a similar capacity with,
another organization or an employee benefit plan, against all expenses and
liabilities (including counsel fees, judgments, fines, excise taxes, penalties
and amounts payable in settlements) reasonably incurred by or imposed upon such
person in connection with any threatened, pending or completed action, suit or
other proceeding, whether civil, criminal, administrative or investigative, in
which he may become involved by reason of his serving or having served in such
capacity (other than a proceeding voluntarily initiated by such person unless he
is successful on the merits, the proceeding was authorized by the Company or the
proceeding seeks a declaratory judgment regarding his own conduct). Such
indemnification 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 proceeding, upon receipt of an undertaking by the
person indemnified to repay such payment if he shall be adjudicated to be not
entitled to indemnification under Article X, which undertaking may be accepted
without regard to the financial ability of such person to make repayment.

     The indemnification provided for in Article X is a contract right inuring
to the benefit of the directors, officers and others entitled to
indemnification. In addition, the indemnification is expressly not exclusive of
any other rights to which such director, officer or other person may be entitled
by contract or otherwise under law, and inures to the benefit of the heirs,
executors and administrators of such a person.

     Section 13(b)(1 1/2) of chapter 156B of the Massachusetts Business
Corporation Law provides that a corporation may, in its Articles of
Organization, eliminate the personal liability of directors to the corporation
and its stockholders for monetary damages for breach of fiduciary duty as a
director, except in circumstances involving (i) a breach of the director's duty
of loyalty to the corporation or its stockholders, (ii) acts or omissions not in
good faith or which involve intentional misconduct or a knowing violation of
law, (iii) loans to insiders and unauthorized distributions, and (iv)
transactions from which the director derived an improper personal benefit.
Article VI(e) of the Company's Articles of Organization provides that no
director shall be personally liable to the Company or its stockholders for
monetary damages for any breach of fiduciary duty as a director, except to the
extent that such exculpation is not permitted under the Massachusetts Business
Corporation Law as in effect when such liability is determined.

    The Company maintains an indemnification insurance policy that covers all
directors and officers of the Company.

ITEM 7. EXEMPTION FROM REGISTRATION CLAIMED.

     Not applicable.

ITEM 8. EXHIBITS.

     See the exhibit index immediately preceding the exhibits attached hereto.

ITEM 9. 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;

               (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; and

               (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, no filing will be made pursuant to paragraph (a)(1)(i) or
(a)(1)(ii) if the information required to be included in a post-effective
amendment by those paragraphs is contained in periodic reports filed with or
furnished to the Commission by the registrant pursuant to Section 13 or Section
15(d) of the Exchange Act that are incorporated by reference in this
Registration Statement.

          (2) That, for the purpose of determining any liability under the
     Securities Act, 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, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act that is incorporated by reference in this 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 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the provisions of the Massachusetts Business Corporation
Law and the registrant's Articles of Organization and By-laws, or otherwise, the
registrant has been advised that in the opinion of the Commission such
indemnification is against public policy as expressed in the Securities 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


                                      -4-


<PAGE>


by a director, officer or a 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 and will be governed by the final
adjudication of such issue.


                                      -5-

                                      -2-
ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Section 67 of chapter 156B of the Massachusetts Business Corporation Law
grants the Company the power to indemnify any director, officer, employee or
agent, to whatever extent permitted by the Company's Articles of Organization,
Bylaws or a vote adopted by the holders of a majority of the shares entitled to
vote thereon, if such indemnitee acted (a) in good faith in the reasonable
belief that his action was in the best interests of the corporation or (b) to
the extent that the matter for which indemnification is sought relates to
service with respect to an employee benefit plan, in the best interests of the
participants or beneficiaries of such employee benefit plan. Such
indemnification may 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 proceeding, upon receipt of an undertaking by the
person indemnified to repay such payment if he shall be adjudicated to be not
entitled to indemnification under the statute.

     Article X of the Company's Bylaws provides that the Company shall, to the
extent legally permissible, indemnify each person who may serve or who has
served at any time as a director or officer of the Company or of any of its
subsidiaries, or who at the request of the Company may serve or at any time has
served as a director, officer or trustee of, or in a similar capacity with,
another organization or an employee benefit plan, against all expenses and
liabilities (including counsel fees, judgments, fines, excise taxes, penalties
and amounts payable in settlements) reasonably incurred by or imposed upon such
person in connection with any threatened, pending or completed action, suit or
other proceeding, whether civil, criminal, administrative or investigative, in
which he may become involved by reason of his serving or having served in such
capacity (other than a proceeding voluntarily initiated by such person unless he
is successful on the merits, the proceeding was authorized by the Company or the
proceeding seeks a declaratory judgment regarding his own conduct). Such
indemnification 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 proceeding, upon receipt of an undertaking by the
person indemnified to repay such payment if he shall be adjudicated to be not
entitled to indemnification under Article X, which undertaking may be accepted
without regard to the financial ability of such person to make repayment.

     The indemnification provided for in Article X is a contract right inuring
to the benefit of the directors, officers and others entitled to
indemnification. In addition, the indemnification is expressly not exclusive of
any other rights to which such director, officer or other person may be entitled
by contract or otherwise under law, and inures to the benefit of the heirs,
executors and administrators of such a person.

     Section 13(b)(1 1/2) of chapter 156B of the Massachusetts Business
Corporation Law provides that a corporation may, in its Articles of
Organization, eliminate the personal liability of directors to the corporation
and its stockholders for monetary damages for breach of fiduciary duty as a
director, except in circumstances involving (i) a breach of the director's duty
of loyalty to the corporation or its stockholders, (ii) acts or omissions not in
good faith or which involve intentional misconduct or a knowing violation of
law, (iii) loans to insiders and unauthorized distributions, and (iv)
transactions from which the director derived an improper personal benefit.
Article VI(e) of the Company's Articles of Organization provides that no
director shall be personally liable to the Company or its stockholders for
monetary damages for any breach of fiduciary duty as a director, except to the
extent that such exculpation is not permitted under the Massachusetts Business
Corporation Law as in effect when such liability is determined.

    The Company maintains an indemnification insurance policy that covers all
directors and officers of the Company.

ITEM 7. EXEMPTION FROM REGISTRATION CLAIMED.

     Not applicable.

ITEM 8. EXHIBITS.

     See the exhibit index immediately preceding the exhibits attached hereto.

ITEM 9. 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;

               (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; and

               (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, no filing will be made pursuant to paragraph (a)(1)(i) or
(a)(1)(ii) if the information required to be included in a post-effective
amendment by those paragraphs is contained in periodic reports filed with or
furnished to the Commission by the registrant pursuant to Section 13 or Section
15(d) of the Exchange Act that are incorporated by reference in this
Registration Statement.

          (2) That, for the purpose of determining any liability under the
     Securities Act, 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, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act that is incorporated by reference in this 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 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the provisions of the Massachusetts Business Corporation
Law and the registrant's Articles of Organization and By-laws, or otherwise, the
registrant has been advised that in the opinion of the Commission such
indemnification is against public policy as expressed in the Securities 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

                                      -4-
by a director, officer or a 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 and will be governed by the final
adjudication of such issue.

                                      -5-
