<P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The Registrant has directors&#146; and officers&#146; liability insurance policies to insure its directors and officers against liability for actions or
omissions occurring in their capacity as a director or officer, subject to certain exclusions or limitations. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The Registrant has also entered into
indemnification agreements with each of its executive officers and directors. The indemnification agreements provide the executive officers and directors with contractual rights to indemnification, expense advancement and reimbursement, to the
fullest extent permitted under Delaware law. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Section&nbsp;145 (&#147;Section&nbsp;145&#148;) of the Delaware General Corporation Law, as the same exists
or may hereafter be amended (the &#147;DGCL&#148;), provides that a Delaware corporation may indemnify any persons who were, are or are threatened to be made, parties to any threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative (other than an action by or in the right of such corporation), by reason of the fact that such person is or was an officer, director, employee or agent of such corporation, or is or was serving at the
request of such corporation as a director, officer, employee or agent of another corporation or enterprise. The indemnity may include expenses (including attorneys&#146; fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by such person in connection with such action, suit or proceeding, provided such person acted in good faith and in a manner he reasonably believed to be in or not opposed to the corporation&#146;s best interests and, with respect to any
criminal action or proceeding, had no reasonable cause to believe that his conduct was illegal. A Delaware corporation may indemnify any persons who are, were or are threatened to be made, a party to any threatened, pending or completed action or
suit by or in the right of the corporation by reasons of the fact that such person was a director, officer, employee or agent of such corporation, or is or was serving at the request of such corporation as a director, officer, employee or agent of
another corporation or enterprise. The indemnity may include expenses (including attorneys&#146; fees) actually and reasonably incurred by such person in connection with the defense or settlement of such action or suit, provided such person acted in
good faith and in a manner he reasonably believed to be in or not opposed to the corporation&#146;s best interests, provided that no indemnification is permitted without judicial approval if the officer, director, employee or agent is adjudged to be
liable to the corporation. Where an officer, director, employee or agent is successful on the merits or otherwise in the defense of any action referred to above, the corporation must indemnify him against the expenses which such officer or director
has actually and reasonably incurred. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Section&nbsp;145 further authorizes a corporation to purchase and maintain insurance on behalf of any person who is
or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation or enterprise, against any liability asserted against him and
incurred by him in any such capacity, arising out of his status as such, whether or not the corporation would otherwise have the power to indemnify him under Section&nbsp;145. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The Registrant&#146;s amended and restated certificate of incorporation limits, to the maximum extent permitted by Delaware law, the personal liability of
directors for monetary damages for breach of their fiduciary duties as a director. The Registrant&#146;s amended and restated <FONT STYLE="white-space:nowrap">by-laws</FONT> provide that directors, officers and employees will be indemnified to the
fullest extent authorized by the DGCL with respect to actions, suits or proceedings. The Registrant&#146;s amended and restated <FONT STYLE="white-space:nowrap">by-laws</FONT> require the Registrant to pay all expenses incurred by a director,
officer or employee in defending any such proceeding. </P>
