New Hampshire Business Corporation Act (the &#147;NHBCA&#148;) provides that a corporation may indemnify an individual made a party to a proceeding because he is or was a director against liability incurred in the proceeding if: (1)&nbsp;he
conducted himself in good faith; and (2)&nbsp;he reasonably believed (i)&nbsp;in the case of conduct in his official capacity with the corporation, that his conduct was in its best interests; and (ii)&nbsp;in all other cases, that his conduct was at
least not opposed to its best interests; and (3)&nbsp;in the case of any criminal proceeding, he had no reasonable cause to believe his conduct was unlawful. A corporation may pay for or reimburse the reasonable expenses incurred by a director who
is a party to a proceeding in advance of the final disposition of the proceeding if (1)&nbsp;the director furnishes the corporation a written affirmation of his good faith belief that he has met the standard of conduct described in the preceding
sentence, (2)&nbsp;the director furnishes the corporation a written undertaking, executed personally or on his behalf, to repay the advance if it is ultimately determined that he did not meet the standard of conduct and (3)&nbsp;a determination is
made that the facts then known to those making the determination would not preclude indemnification. Unless a corporation&#146;s Articles of Incorporation provide otherwise, the corporation may indemnify and advance expenses to an officer, employee
or agent of the corporation who is not a director to the same extent as to a director. A corporation may not indemnify a director (x)&nbsp;in connection with a proceeding by or in the right of the corporation in which the director was adjudged
liable to the corporation; or (y)&nbsp;in connection with any other proceeding charging improper personal benefit to him, whether or not involving action in his official capacity, in which he was adjudged liable on the basis that personal benefit
was improperly received by him. Unless limited by its Articles of Incorporation, a corporation shall indemnify a director or officer who was wholly successful, on the merits or otherwise, in the defense of any proceeding to which he was a party
because he is or was a director or officer of the corporation against reasonable expenses incurred by him in connection with the proceeding. A corporation may purchase and maintain insurance on behalf of an individual who is or was a director,
officer, employee, or agent of the corporation, or who, while a director, officer, employee or agent of the corporation, is or was serving at the request of the corporation as a director, officer, partner, trustee, employee, or agent of another
foreign or domestic corporation, partnership, joint venture, trust, employee benefit plan, or other enterprise, against liability asserted against or incurred by him in that capacity or arising from his status as a director, officer, employee, or
agent, whether or not the corporation would have power to indemnify him against the same liability under the NHBCA. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px; text-indent:4%"><FONT STYLE="font-family:Times New Roman" SIZE="2">Article
XII of the Registrant&#146;s Amended and Restated By-Laws provides that the Registrant shall indemnify any 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

applicable provisions of the NHBCA. Any indemnification under Article XII shall be made by the Registrant with respect to directors or other persons after a determination that the person to be indemnified has met the standards of conduct set forth
in the NHBCA, such determination to be made by the Board of Directors, by majority vote of a quorum, or by other persons authorized to make such a determination under the NHBCA. </FONT></P>

of inducing persons to serve and to continue to serve the Registrant without concern that their service may expose them to personal financial harm. It is to be broadly construed, applied and implemented in light of that purpose. It is not to be
exclusive of any other right to which any such person is entitled under any agreement, vote of the stockholders or the Board of Directors, statute, or as a matter of law, or otherwise, nor is it to be construed to limit or confine in any respect the
power of the Board of Directors to grant indemnity pursuant to any applicable statutes or laws of the State of New Hampshire. The provisions of Article XII are separable, and, if any provision or portion thereof is for any reason held inapplicable,
illegal or ineffective, such holding will not affect any other right of indemnification existing under Article XII or otherwise. As used in Article XII, the term &#147;person&#148; includes heirs, executors, administrators or other legal
representatives. As used in Article XII, the terms &#147;director&#148; and &#147;officer&#148; include persons elected or appointed as officers by the Board of Directors, persons elected as directors by the stockholders or by the Board of
Directors, and persons who serve by vote or at the request of the Registrant as directors, officers or trustees of another organization in which the Registrant has any direct or indirect interest as a shareholder, creditor or otherwise. </FONT></P>

against any liability asserted against, and incurred by, such person in any such capacity, or arising out of such person&#146;s status as such, whether or not the Registrant would have the power to indemnify such person against such liability under
the provisions of the NHBCA. The obligation to indemnify and reimburse such person under the Registrant&#146;s Amended and Restated By-Laws, if applicable, will be reduced by the amount of any such insurance proceeds paid to such person, or the
representatives or successors of such person. </FONT></P> <P STYLE="margin-top:18px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2"><B>I<SMALL>TEM&nbsp;</SMALL>16: E<SMALL>XHIBITS</SMALL> </B></FONT></P>
