Registrant has adopted provisions in its Second Amended and Restated Certificate
of Incorporation that limit or eliminate the personal liability of the
Registrant&#8217;s directors to the maximum extent permitted by the Delaware General
Corporation Law (the &#8220;DGCL&#8221;). The DGCL expressly permits a corporation to
provide that its directors will not be liable for monetary damages for a breach
of their fiduciary duties as directors, except for liability: (i) for any breach
of the director&#8217;s duty of loyalty to the corporation or its stockholders; (ii)
for acts or omissions not in good faith or which involve intentional misconduct
or a knowing violation of law; (iii) under Section 174 of the DGCL (relating to
unlawful stock repurchases, redemptions or other distributions or payment of
dividends); or (iv) for any transaction from which the director derived an
improper personal benefit. These limitations of liability do not generally
affect the availability of equitable remedies such as injunctive relief or
rescission.</font></div>

Registrant&#8217;s Second Amended and Restated Certificate of Incorporation also
obligates it to indemnify the Registrant&#8217;s directors, officers, employees and
agents to the fullest extent permitted under the DGCL, subject to limited
exceptions.&#160;&#160;Section 145 of the DGCL provides, in effect, that any
person made a party to any action by reason of the fact that he or she is or was
our director, officer, employee or agent may and, in certain cases, must be
indemnified by us against, in the case of a non-derivative action, judgments,
fines, amounts paid in settlement and reasonable expenses (including attorneys&#8217;
fees) incurred by him or her as a result of such action, and in the case of a
derivative action, against expenses (including attorneys&#8217; fees), if in either
type of action he or she acted in good faith and in a manner he or she
reasonably believed to be in or not opposed to our best
interests.&#160;&#160;This indemnification does not apply, (i) in a derivative
action, to matters as to which it is adjudged that the director, officer,
employee or agent is liable to us, unless upon court order it is determined
that, despite such adjudication of liability, but in view of all the
circumstances of the case, he or she is fairly and reasonably entitled to
indemnity for expenses, and, (ii) in a non-derivative action, to any criminal
proceeding in which such person had no reasonable cause to believe his or her
conduct was unlawful.&#160;&#160;Also, the Registrant may be required to advance
expenses to its directors, officers, employees and agents in connection with
legal proceedings, subject to limited exceptions.</font></div>

Registrant may enter into separate indemnification agreements with its directors

contained in the DGCL. These indemnification agreements could require the
Registrant, among other things, to indemnify its directors and officers against
liabilities that may arise by reason of their status or service as directors and
officers, other than liabilities arising from willful misconduct. These
indemnification agreements may also require the Registrant to advance any
expenses incurred by the directors and officers as a result of any proceeding
against them as to which they could be indemnified and to obtain directors&#8217; and
officers&#8217; insurance if available on reasonable terms.</font><br></div>

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.</font></div><br>
