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 foregoing provisions summarized in Item 6 or otherwise, the
Registrant has been advised that, in the opinion of the SEC, such
indemnification is against public policy as expressed in the 1933 Act, and is,
therefore, unenforceable.&#160;&#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.</font></div>

Indemnification of Directors
and Officers
Delaware
General Corporation Law
Section
102(b)(7) of the Delaware General Corporation Law permits a corporation to
provide in its certificate of incorporation that a director of the corporation
shall not be personally liable to the corporation or its stockholders for
monetary damages for breach of fiduciary duty as a director, except for
liability for any breach of the director's duty of loyalty to the corporation or
its stockholders, for acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, for unlawful payments of
dividends or unlawful stock repurchases, redemptions or other distributions, or
for any transaction from which the director derived an improper personal
benefit.
Section
145 of the Delaware General Corporation Law, as amended, provides that a
corporation may indemnify directors and officers as well as other employees and
individuals against expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred by such person in
connection with any threatened, pending or completed actions, suits or
proceedings in which such person is made a party by reason of such person being
or having been a director, officer, employee or agent of the corporation,
subject to certain
limitations.
The Delaware General Corporation Law provides that Section 145 is not exclusive
of other rights to which those seeking indemnification may be entitled under any
bylaw, agreement, vote of stockholders or disinterested directors or
otherwise.
Amended
and Restated Certificate of Incorporation and Second Amended and Restated
Bylaws
Article
Eight of our amended and restated certificate of incorporation provides for
indemnification by us of our directors, officers and employees to the fullest
extent permitted by Delaware law. Article Eight also provides that we may
maintain insurance on behalf of our directors, officers and
employees.
Indemnification
Agreements and Directors' and Officers' Liability Insurance
The
Registrant expects to maintain standard policies of insurance that provide
coverage (1) to our directors and officers against loss rising from claims
made by reason of breach of duty or other wrongful act, and (2) to us with
respect to indemnification payments that we may make to such directors and
officers.
We have
also entered into separate indemnification agreements with our directors and
officers which may be broader than the indemnification provisions contained in
Delaware law.

Item
9.
Undertakings
a.    The
undersigned Registrant hereby undertakes:
(1)  to
file, during any period in which offers or sales are being made, a
post-effective amendment to this Registration Statement (i) to include any
prospectus required by Section 10(a)(3) of the 1933 Act, (ii) to
reflect in the prospectus any facts or events arising after the effective date
of this Registration Statement (or the most recent post-effective amendment
thereof) which, individually or in the aggregate, represent a fundamental change
in the information set forth in this Registration Statement and (iii) to
include any material information with respect to the plan of distribution not
previously disclosed in this Registration Statement or any material change to
such information in this Registration Statement;
provided
, however,
that clauses (1)(i) and (1)(ii) shall not apply if the information
required to be included in a post-effective amendment by those paragraphs is
contained in reports filed with or furnished to the SEC by the Registrant
pursuant to Section 13 or Section 15(d) of the 1934 Act that are
incorporated by reference in this Registration Statement;
(2) 
that for the purpose of determining any liability under the 1933 Act, each such
post-effective amendment shall be deemed to be a new registration statement
relating to the securities offered therein and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof;
and
(3)  to
remove from registration by means of a post-effective amendment any of the
securities being registered which remain unsold at the termination of the
offering.
b.    The
undersigned Registrant hereby undertakes that, for purposes of determining any
liability under the 1933 Act, each filing of the Registrant's annual report
pursuant to Section 13(a) or Section 15(d) of the 1934 Act that is incorporated
by reference into this Registration Statement shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.
c.    Insofar
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 foregoing provisions summarized in Item 6 or otherwise, the
Registrant has been advised that, in the opinion of the SEC, such
indemnification is against public policy as expressed in the 1933 Act, and is,
therefore, unenforceable.  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.
