for breach of fiduciary duty as a director or officer, except that no provision may limit or eliminate the liability of (i) a director
or officer for a breach of the duty of loyalty, (ii) a director or officer for acts or omissions not in good faith or that involve intentional
misconduct or a knowing violation of law, (iii) a director for the payment of a dividend or approval of a stock repurchase or redemption

the person is or was a director, officer, employee or agent of the Company, or is or was serving at the request of the corporation as
a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against expenses,
including attorneys&rsquo; fees, judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection
with such action, suit or proceeding. The power to indemnify applies (a)&nbsp;if such person is successful on the merits or otherwise
in defense of any action, suit or proceeding or (b)&nbsp;if such person is acting in good faith and in a manner such person reasonably
believed to be in the best interest, or not opposed to the best interest, of the Company, and with respect to any criminal action or proceeding,

of expenses shall be made in the event of any adjudication of liability to the Company, unless the court believes that in light of all
the circumstances indemnification should apply.</P>

Item 6.
Indemnification
of Directors and Officers.
Section 102 of the General Corporation Law
of the State of Delaware (the "DGCL") allows a corporation to adopt a provision of its certificate of incorporation that limits
or eliminates the personal liability of directors and officers of a corporation to the corporation or its stockholders for monetary damages
for breach of fiduciary duty as a director or officer, except that no provision may limit or eliminate the liability of (i) a director
or officer for a breach of the duty of loyalty, (ii) a director or officer for acts or omissions not in good faith or that involve intentional
misconduct or a knowing violation of law, (iii) a director for the payment of a dividend or approval of a stock repurchase or redemption
in violation of the DGCL, (iv) a director or officer for a transaction from which the director or officer obtained an improper personal
benefit, or (v) an officer in an action by or in the right of the corporation, including any derivative action.
Section 145 of the DGCL provides, among other
things, that a corporation may 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—other than an action by or in the right of the Company—by reason of the fact that
the person is or was a director, officer, employee or agent of the Company, or is or was serving at the request of the corporation 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 the person in connection
with such action, suit or proceeding. The power to indemnify applies (a) if such person is successful on the merits or otherwise
in defense of any action, suit or proceeding or (b) if such person is acting in good faith and in a manner such person reasonably
believed to be in the best interest, or not opposed to the best interest, of the Company, and with respect to any criminal action or proceeding,
had no reasonable cause to believe his or her conduct was unlawful. The power to indemnify applies to actions brought by or in the right
of the Company as well as but only to the extent of defense expenses, including attorneys' fees actually and reasonably incurred,
but does not apply to judgments or amounts paid in settlement, and with the further limitation that in such actions no indemnification
of expenses shall be made in the event of any adjudication of liability to the Company, unless the court believes that in light of all
the circumstances indemnification should apply.
Our Certificate of Incorporation eliminates the
liability of our directors for monetary damages to us and our stockholders to the fullest extent permitted by law. Our Certificate of
Incorporation and Bylaws, as amended and restated, provide that we shall indemnify our directors and officers, including when acting as
directors, officers, employees and agents of other enterprises, to the fullest extent permitted by the DGCL.
