Item 6.                                 Indemnification of Directors and Officers

Article VI.C. of our amended and restated articles of organization provides that a director shall not have personal liability to us or our stockholders for monetary damages arising out of the director’s breach of fiduciary duty as our director, to the maximum extent permitted by Massachusetts law.  Article VI.D. of our amended and restated articles of organization and Section 8.11 of our amended and restated bylaws provide that we shall, to the fullest extent authorized by Massachusetts law, indemnify each person who is, or shall have been, one of our directors or officers or who is or was one of our directors or employees and is serving, or shall have served, at our request, as a director or officer of another organization or in any capacity with respect to any of our employee benefit plans, against all liabilities and expenses (including judgments, fines, penalties, amounts paid or to be paid in settlement, and reasonable attorneys’ fees) imposed upon or incurred by any such person in connection with, or arising out of, the defense or disposition of any action, suit or other proceeding, whether civil or criminal, in which they may be involved by reason of being or having been such a director or officer or as a result of service with respect to any such employee benefit plan.

Section 8.51 of Chapter 156D of the Massachusetts General Laws provides that a corporation may indemnify a director against liability if:

(1)                                 (i) he conducted himself in good faith; and

(ii) 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

(iii) in the case of any criminal proceeding, he had no reasonable cause to believe his conduct was unlawful; or

(2)  he engaged in conduct for which he shall not be liable under a provision of the corporation’s articles of organization authorized by Section 2.02(b)(4) of Chapter 156D of the Massachusetts General Laws.

Section 2.02(b)(4) of Chapter 156D of the Massachusetts General Laws provides that the articles of organization of a corporation may state a provision eliminating or limiting the personal liability of a director to a corporation for monetary damages for breach of fiduciary duty as a director, provided, however, that such provision shall not eliminate or limit the liability of a director (a) for any breach of the director’s duty of loyalty to the corporation or its stockholders, (b) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (c) for improper distributions to shareholders, or (d) for any transaction from which the director derived an improper personal benefit.

Section 8.52 of Chapter 156D of the Massachusetts General Laws requires a corporation to indemnify a director who was wholly successful, on the merits or otherwise, in the defense of any proceeding to which he was a party because he was a director against reasonable expenses incurred by him. Section 8.56 of Chapter 156D of the Massachusetts General Laws allows corporations to indemnify officers to the same or greater extent as directors.

4

The effect of these provisions would be to permit indemnification by us for, among other liabilities, liabilities arising out of the Securities Act of 1933, as amended.

Section 8.57 of Chapter 156D of the Massachusetts General Laws also affords a Massachusetts corporation the power to obtain insurance on behalf of its directors and officers against liabilities incurred by them in those capacities. We have procured a directors and officers liability and company reimbursement liability insurance policy that (a) insures our directors and officers against losses (above a deductible amount) arising from certain claims made against them by reason of certain acts or omissions of such directors or officers in their capacity as directors or officers and (b) insures us against losses (above a deductible amount) arising from any such claims, but only if we are required or permitted to indemnify such directors or officers for such losses under statutory or common law or under provisions of our amended and restated articles of organization or amended and restated by-laws.

Item 7.                                 Exemption from Registration Claimed

Not Applicable.

Item 8.                                 Exhibits.

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 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,

6

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 Registration Fee” table in the effective 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 (a)(1)(i) and (a)(1)(ii) do not apply 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 Securities and Exchange Commission 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.

(4)  That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i)  Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii)  Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii)  The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv) Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(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 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

7

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 Act and will be governed by the final adjudication of such issue.
