<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Section&nbsp;8.51 of the Massachusetts Business Corporation Act, under which the registrant is
governed, provides that a corporation may indemnify a director who is a party to a proceeding
because he is a director against liability incurred in the proceeding if he conducted himself in
good faith and 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&nbsp;8.52 of the Massachusetts Business Corporation Act requires corporations to indemnify any
director who was wholly successful in the defense of any proceeding to which he was a party because
he was a director of the corporation against reasonable expenses incurred by him in connection with
the proceeding.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Section&nbsp;8.53 of the Massachusetts Business Corporation Act provides that, before the final
disposition of a proceeding, a corporation may advance funds to pay for or reimburse the reasonable
expenses incurred by a director who is party to such proceeding because he is a director if he
delivers to the corporation (a)&nbsp;a written affirmation of his good faith belief that he has met the
relevant standard of good faith described in Section&nbsp;8.51 of the Massachusetts Business Corporation
Act or that the proceeding involves conduct for which liability has been eliminated pursuant to
Section&nbsp;2.02 of the Massachusetts Business Corporation Act and (b)&nbsp;a written undertaking with an
unlimited general obligation of the director to repay any funds advanced if he is not entitled to
mandatory indemnification under Section&nbsp;8.52 and it is ultimately determined, under Section&nbsp;8.54 or
Section&nbsp;8.55 that he does not meet the relevant standard of conduct described in Section&nbsp;8.51.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Section&nbsp;8.56 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&nbsp;8.56 also provides that an officer of the corporation who is not
a director is entitled to mandatory indemnification under Section&nbsp;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.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Section&nbsp;2.02 of the Massachusetts Business Corporation Act provides that the articles of
organization of a corporation may contain a provision eliminating or limiting the personal
liability of a director to the corporation for monetary damages for breach of a fiduciary duty as a
director notwithstanding any provision of law imposing such liability; provided, however, that such
provision shall not eliminate or limit the liability of a director (1)&nbsp;for any breach of the
director&#146;s duty of loyalty to the corporation or its shareholders, (2)&nbsp;for acts or omissions not in
good faith or which involve intentional misconduct or a knowing violation of law, (3)&nbsp;for improper
distributions to under Sections&nbsp;6.40 of the Massachusetts Business Corporation Act or (4)&nbsp;for any
transaction from which the director derived an improper personal benefit.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Article&nbsp;6 of the Company&#146;s Restated Articles of Organization provides that the registrant

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Section&nbsp;8.57 of the Massachusetts Business Corporation Act also contains provisions
authorizing a corporation to obtain insurance on behalf of any director or officer of the
corporation against liabilities, whether or not the corporation would have the power to indemnify
against such liabilities. The registrant maintains directors&#146; and officers&#146; liability insurance
which may protect the registrant&#146;s directors and officers against costs and liabilities imposed
upon them in their roles with the registrant, including in circumstances under which
indemnification would not be permitted under the Massachusetts Business Corporation Act.

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 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.

- 1 -
Item 5. Interests of Named Experts and Counsel.
Wilmer Cutler Pickering Hale and Dorr LLP has opined as to the legality of the securities
being offered by this registration statement.
Item 6. Indemnification of Directors and Officers.
Section 8.51 of the Massachusetts Business Corporation Act, under which the registrant is
governed, provides that a corporation may indemnify a director who is a party to a proceeding
because he is a director against liability incurred in the proceeding if he conducted himself in
good faith and 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 the Massachusetts Business Corporation Act requires corporations to indemnify any
director who was wholly successful in the defense of any proceeding to which he 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 the Massachusetts Business Corporation Act provides that, before the final
disposition of a proceeding, a corporation may advance funds to pay for or reimburse the reasonable
expenses incurred by a director who is party to such proceeding because he is a director if he
delivers to the corporation (a) a written affirmation of his good faith belief that he has met the
relevant standard of good faith described in Section 8.51 of the Massachusetts Business Corporation
Act or that the proceeding involves conduct for which liability has been eliminated pursuant to
Section 2.02 of the Massachusetts Business Corporation Act and (b) a written undertaking with an
unlimited general obligation of the director to repay any funds advanced if he is not entitled to
mandatory indemnification under Section 8.52 and it is ultimately determined, under Section 8.54 or
Section 8.55 that he does not meet the relevant standard of conduct described in Section 8.51.
Section 8.56 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 the 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 2.02 of the Massachusetts Business Corporation Act provides that the articles of
organization of a corporation may contain a provision eliminating or limiting the personal
liability of a director to the corporation for monetary damages for breach of a fiduciary duty as a
director notwithstanding any provision of law imposing such liability; provided, however, that such
provision shall not eliminate or limit the liability of a director (1) for any breach of the
director's duty of loyalty to the corporation or its shareholders, (2) for acts or omissions not in
good faith or which involve intentional misconduct or a knowing violation of law, (3) for improper
distributions to under Sections 6.40 of the Massachusetts Business Corporation Act or (4) for any
transaction from which the director derived an improper personal benefit.
Article 6 of the Company's Restated Articles of Organization provides that the registrant
shall indemnify each person who was or is a party or is threatened to be made a party to any
threatened,
- 2 -
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, or has agreed
to serve, at the request of the registrant, as a director or officer of, or in a similar capacity
with, another organization or in any capacity with respect to any employee benefit plan of the
registrant, or by reason of any action alleged to have been taken or omitted in such capacity
against all expenses (including attorneys' fees), judgments and fines incurred by such person or on
his or her behalf in connection with such action, suit or proceeding, unless such person shall be
finally adjudicated in such action, suit or proceeding not to have acted in good faith in the
reasonable belief that his action was in the best interests of the registrant or, to the extent
such matter relates to service with respect to an employee benefit plan, in the best interests of
the participants or beneficiaries of such employee benefit plan.
Section 2 of Article V of the registrant's by-laws provides that each director and officer of
the registrant, and any person who, at the request of the registrant, serves as a director or
officer of another organization shall be indemnified by the registrant against any cost, expense
(including attorneys' fees), judgment, liability and/or amount paid in settlement reasonably
incurred by or imposed upon him in connection with any action, suit or proceeding (including any
proceeding before any administrative or legislative body or agency), to which he may be made a
party or otherwise involved or with which he shall be threatened, by reason of his being, or
related to his status as, a director or officer of the registrant or of any other organization,
which other organization he serves or has served as director or officer at the request of the
registrant (whether or not he continues to be an officer or director of the registrant or such
other organization at the time such action, suit or proceeding is brought or threatened), unless
such indemnification is prohibited by the Business Corporation Law of the Commonwealth of
Massachusetts.
Section 8.57 of the Massachusetts Business Corporation Act also contains provisions
authorizing a corporation to obtain insurance on behalf of any director or officer of the
corporation against liabilities, whether or not the corporation would have the power to indemnify
against such liabilities. The registrant maintains directors' and officers' liability insurance
which may protect the registrant's directors and officers against costs and liabilities imposed
upon them in their roles with the registrant, including in circumstances under which
indemnification would not be permitted under the Massachusetts Business Corporation Act.
Item 7. Exemption from Registration Claimed.
Not applicable.
Item 8. Exhibits.
The Index to Exhibits immediately preceding the exhibits is incorporated herein by reference.
Item 9. Undertakings.
1.
Item
512(a)
of Regulation S-K
. 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,
- 3 -
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 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.
2.
Item
512(b)
of Regulation S-K
. 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 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.
Item
512(h)
of Regulation S-K
. 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 Securities and Exchange 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.
