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 Pursuant to the requirements of the Securities Act of 1933, the registrant has duly caused this Amendment No. 1 to be signed on its behalf by the undersigned, thereunto duly authorized, in the Town of Marlborough, Commonwealth of Massachusetts, on December 15, 1994.
