<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Section&nbsp;145 of the DGCL provides 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, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that the person 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, partnership or other enterprise, against all expenses (including attorneys&#146; fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by them in connection with such action, suit or proceeding if he or she acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interest of the corporation and, with respect to any criminal action or proceeding, if he or she had no reasonable cause to believe their conduct was unlawful. Section&nbsp;145 further provides that a corporation similarly may indemnify any such person serving in any such capacity who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor, against expenses (including attorneys&#146; fees) actually and reasonably incurred in connection with the defense or settlement of the action or suit if he or she acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation, except that no indemnification may be made against expenses in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation, unless and only to the extent that the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which such court shall deem proper.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Article&nbsp;Eight of the Certificate of Incorporation provides that a director of the Registrant shall not be personally liable to the Registrant or its stockholders for monetary damages for breach of fiduciary duty as a director, except for liability (i)&nbsp;for any breach of the director&#146;s duty of loyalty to the Registrant or its stockholders, (ii)&nbsp;for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii)&nbsp;under Section&nbsp;174 of the DGCL, or (iv)&nbsp;for any transaction from which the director derived an improper personal benefit. If the DGCL is amended to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of a director of the Registrant shall be eliminated or limited to the fullest extent permitted by the DGCL as so amended. Any repeal or modification of Article&nbsp;Eight of the Bylaws by the stockholders shall not adversely affect any right or protection of a director of the Registrant existing at the time of such repeal or modification.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The Bylaws provide that the Registrant will indemnify to the fullest extent permitted by Delaware law, including the DGCL as described above, any person who was or is a party or is threatened to be made a party to, or is otherwise involved in, any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (whether or not an action by or in right of the Registrant) (hereinafter a &#147;proceeding&#148;), by reason of the fact that he or she is or was a director or officer of the Registrant, or, while serving as a director or officer of the Registrant, is or was serving at the Registrant&#146;s request as a director, officer, employee or agent of another entity, or by reason of any action alleged to have been taken or omitted in such capacity against all expense, liability and loss (including attorneys&#146; fees) reasonably incurred or suffered. However, except with respect to certain proceedings to enforce rights to indemnification as described below, the Registrant will indemnify any such officer or director in connection with a proceeding initiated by that officer or director only if the proceeding was authorized by the Registrant&#146;s board of directors.</font></p>
<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">This right to indemnification also includes the right to be paid in advance expenses (including attorneys&#146; fees) incurred in defending any such proceeding to the fullest extent permitted by Delaware law. However, if the DGCL requires an advancement of expenses incurred by an officer or director in his or her capacity as such (and not in any other capacity in which service was or is rendered), the Registrant will advance expenses only upon delivery to it of an undertaking by or on behalf of the officer or director, to repay all amounts advanced if it is ultimately determined by final judicial decision from which there is no further right to appeal that the officer or director is not entitled to be indemnified for expenses incurred.</font></p>
<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The Bylaws further provide that the Registrant 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, whether civil, criminal, administrative or investigative (whether or not an action by or in right of the Registrant) by reason of the fact that the person is or was an employee (other than an officer) or agent of the Registrant, or, while serving as an employee (other than an officer) or agent of the Registrant, is or was serving at the Registrant&#146;s request as a director, officer, employee or agent of another entity, to the extent (i)&nbsp;permitted by Delaware law, and (ii)&nbsp;authorized in the sole discretion of the Registrant&#146;s Chief Executive Officer and at least one other of the following officers of the Registrant: the President, the Chief Financial Officer, or the General Counsel. The Registrant may, to the extent permitted by Delaware law and authorized as described in (ii)&nbsp;of the preceding sentence, pay expenses (including attorneys&#146; fees) reasonably incurred by any employee or agent of the Registrant in defending any proceeding in advance of the final disposition, upon terms and conditions that the officer authorizing such expense advancement may determine in his or her sole discretion.</font></p>

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.</p>
