Item 6. Indemnification of Directors and Officers.
The Company is a Massachusetts corporation. Section 2.02(b)(4) of Chapter 156D of the Massachusetts Business Corporation Act allows a corporation to eliminate or limit the personal liability of a director of a corporation to the corporation for monetary damages for a breach of fiduciary duty as a director; provided, however, that such provision shall not eliminate or limit the liability of a director (i) for any breach of the director's duty of loyalty to the corporation or its shareholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) for improper distributions under Section 6.40 or (iv) for any transaction from which a director derived an improper personal benefit.
Section 8.51 of Chapter 156D of the Massachusetts Business Corporation Act provides that a corporation may indemnify a director against liability incurred in a proceeding if such director is a party to the proceeding because he is a director and:
•
he conducted himself in good faith;
•
he reasonably believed that his conduct was in the best interests of the corporation or that his conduct was at least not opposed to the best interests of the corporation; and
•
in the case of any criminal proceeding, he had no reasonable cause to believe his conduct was unlawful.
Section 8.52 of Chapter 156D of the Massachusetts Business Corporation Act provides that a corporation shall indemnify a director who was wholly successful, on the merits or otherwise, in the defense of any proceeding to which the director was a party because he was a director of the corporation against reasonable expenses incurred by him in connection with the proceeding.
Section 8.53 of
Chapter 156D of the Massachusetts Business Corporation Act authorizes a corporation, subject to certain conditions, to pay for, in advance, a director's reasonable expenses in a proceeding.
Section 8.56 of Chapter 156D of the Massachusetts Business Corporation Act provides that a corporation may indemnify and advance expenses to an officer of the corporation who is a party to a proceeding because he is an officer of the corporation:
•
to the same extent as a director; and
•
if he is an officer but not a director, to such further extent as may be provided by the articles of organization, the bylaws, a resolution of the board of directors, or contract, except for liability arising out of acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law.
Section 8.56 also provides that an officer of a corporation who is not a director is entitled to mandatory indemnification under Section 8.52, and that the officer may apply to a court for indemnification or an advance for expenses, in each case to the same extent to which a director may be entitled to indemnification or advance under those provisions.
Section 8.57 of Chapter 156D of the Massachusetts Business Corporation Act also affords a Massachusetts corporation the power to obtain insurance on behalf of its directors and officers against liabilities incurred by them in these and other capacities.
The Company's Restated Articles of Organization, as amended, and Amended and Restated By-Laws provide for such indemnification of the officers and directors of the Company and its subsidiaries to the extent permitted by law. Reference is made to Article VI of the Company's Restated Articles of Organization, filed as Exhibit 3.1A to the Company's Current Report on Form 8-K filed on May 19, 2005, and Article VII of the Company's Amended and Restated By-Laws, filed as Exhibit 3.4D to the Company's Current Report on Form 8-K filed on March 16, 2022, and incorporated herein by reference, for the applicable provisions regarding the indemnification of officers and directors.

Item 9. 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 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. 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 20% change in the maximum aggregate offering price set forth in the "Calculation of Filing Fee Table" or "Calculation of Registration Fee" table, as applicable in the effective registration statement;
(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 (1)(i) and (1)(ii) do not apply to this registration statement on
II-3
Form S-8 if the information required to be included in a post-effective amendment by those paragraphs is contained in 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 the 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.
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 (and where applicable, each filing of an employee benefit plan's annual report pursuant to section 15(d) of the Exchange Act) 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.
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 foregoing provisions, 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 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 and will be governed by the final adjudication of such issue.
