action by reason of the fact that he is or was a director, officer, employee or
agent of the Registrant may and, in some cases, must be indemnified by the
Registrant against, in the case of a non-derivative action, judgments, fines,
amounts paid in settlement and reasonable expenses (including attorneys&#146; fees)
incurred by him as a result of such action, and in the case of a derivative
action, against expenses (including attorneys&#146; fees), if in either type of
action he acted in good faith and in a manner he reasonably believed to be in
or not opposed to the best interests of the Registrant. This indemnification
does not apply, in a derivative action, to matters as to which it is adjudged
that the director, officer, employee or agent is liable to the Registrant,
unless upon court order it is determined that, despite such adjudication of
liability, but in view of all the circumstances of the case, he is fairly and
reasonably entitled to indemnity for expenses, and, in a non-derivative action,
to any criminal proceeding in which such person had no reasonable cause to
believe his conduct was unlawful.</font></p>

that no director shall be liable to the Registrant or its stockholders for
monetary damages for breach of fiduciary duty as a director to the fullest
extent permitted by the DGCL.&#160; The
Registrant&#146;s bylaws require it to indemnify its directors and executive
officers to the fullest extent permitted by Delaware law. The Registrant has
entered into indemnification agreements with all of its directors and executive
officers and has purchased directors&#146; and officers&#146; liability insurance.</font></p>

as indemnification for liabilities arising under the 1933 Act may be permitted
to directors, officers, or controlling persons of the Registrant pursuant to
the indemnification provisions summarized in Item 6 or otherwise, the Registrant
has been advised that, in the opinion of the Commission, such indemnification
is against public policy as expressed in the 1933 Act, and is, therefore,
unenforceable.&#160; 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 1933
Act and will be governed by the final adjudication of such issue.</p>
