Interests of Named Experts and Counsel -------------------------------------- The legality of the Common Stock being offered hereby will be passed for the Registrant by Hale and Dorr LLP, Boston, Massachusetts. Item 6. Indemnification of Directors and Officers ----------------------------------------- Section 145 of the Delaware General Corporation Law grants the Registrant the power to indemnify each person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit, or proceeding, whether civil, criminal, administrative, or investigative by reason of the fact that he is or was a director, officer, employee or agent of the Registrant, or is or was serving at the request of the Registrant as a director, officer, employee or agent of another corporation, partnership, joint venture, trust, or other enterprise, against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with such action, suit or proceeding if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the Registrant, and with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful; provided, however, no indemnification shall be made in connection with any proceeding brought by or in the right of the Registrant where the person involved is adjudged to be liable to the Registrant except to the extent approved by a court. Article NINTH of the Registrant's Restated Certificate of Incorporation and Article VII of the Registrant's Restated By-laws provide that the Registrant shall, to the fullest extent permitted by applicable law, indemnify each person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit, or proceeding by reason of the fact that he is or was, or has agreed to become, a director or officer of the Registrant, or is or was serving at the written request of the Registrant, as a director, officer or trustee of, or in a similar capacity with, another corporation, partnership, joint venture, trust, or other enterprise. The indemnification provided for in each of Article NINTH and Article VII is expressly not exclusive of any other rights to which those seeking indemnification may be entitled under any law, agreement, or vote of stockholders or disinterested directors or otherwise, and shall inure to the benefit of the heirs, executors, and administrators of such persons. Article VII also provides that the Registrant shall have the power to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee, or agent of the Registrant, or is or was serving at the request of the Registrant, as a director, trustee, partner, officer, employee, or agent of another corporation, partnership, joint venture, trust, or other enterprise, against any liability asserted against and incurred by such person in any such capacity. Pursuant to Section 102(b)(7) of the Delaware General Corporation Laws, Article EIGHTH of the Registrant's Restated Certificate of Incorporation eliminates a director's personal liability for monetary damages to the Registrant and its stockholders for breaches of fiduciary duty as a director, except in circumstances involving a breach of a director's duty of loyalty to the Registrant or its stockholders, acts or omissions not in good faith or which involve intentional misconduct or knowing violation of the law, self-dealing, or the unlawful payment of dividends or repurchase of stock. The Registrant maintains an insurance policy on behalf of itself and certain of its subsidiaries, and on behalf of the directors and officers thereof, covering certain liabilities which may arise as a result of the actions of the directors and officers. The Registrant has entered into agreements with all of its directors affirming the Registrant's obligation to indemnify them to the fullest extent permitted by law and providing various other protections. Item 7. Exemption from Registration Claimed ----------------------------------- Not applicable. Item 8. Exhibits -------- The Exhibit Index immediately preceding the exhibits is incorporated herein by reference. Item 9. Undertakings ------------ 1. 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; 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, that paragraphs (i) and (ii) do not apply 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 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 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. 2. 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 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. 3. 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. SIGNATURES Pursuant to the requirements of the Securities Act of 1933, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing this Post-Effective Amendment No. 1 on Form S-8, and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the Town of Andover, Commonwealth of Massachusetts on March 9, 2000.
