</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Registrant is a Delaware corporation. Section&nbsp;145 of the Delaware General Corporation Law
(the &#147;DGCL&#148;) provides that, in certain circumstances, a corporation may indemnify its directors and
officers against expenses (including attorneys&#146; fees), judgments, fines and amounts paid in
settlement actually and reasonably incurred as a result of any actual or threatened action, suit or
proceeding against such directors or officers, or by or in the right of any other enterprise which
such directors and officers served in any capacity at the request of the corporation, by reason of
the fact that such person acted in any of the capacities set forth above, if such director or
officer (i)&nbsp;acted in good faith and in a manner which he or she reasonably believed to be in or not
opposed to the best interests of the corporation, and (ii)&nbsp;in criminal actions or proceedings, had
no reasonable cause to believe that his or her conduct was unlawful. A corporation is required to
indemnify against reasonable expenses (including attorneys&#146; fees) incurred by any director or
officer who successfully defends any such action. The DGCL also provides for indemnification of
officers and directors in actions by or in the right of the corporation, subject to certain
exceptions. Indemnification provided by these provisions of the DGCL is not exclusive of any other
rights to which a director or officer may be entitled. The foregoing statements are subject to the
detailed provisions of the DGCL.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Article&nbsp;VII of the Registrant&#146;s By-laws provides that the Registrant shall indemnify any
officer or director of the Registrant to the extent, in the manner, and subject to compliance with
the applicable standards of conduct, provided by Section&nbsp;145 of the DGCL. It also provides that
the Registrant shall indemnify and advance expenses to the directors and officers of the Registrant
to the fullest extent permitted by law.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Registrant maintains directors&#146; and officers&#146; liability insurance covering all directors
and officers of the Registrant against claims arising out of the performance of their duties.

Item 6.
Indemnification of Directors and Officers
.
The Registrant is a Delaware corporation. Section 145 of the Delaware General Corporation Law
(the "DGCL") provides that, in certain circumstances, a corporation may indemnify its directors and
officers against expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement actually and reasonably incurred as a result of any actual or threatened action, suit or
proceeding against such directors or officers, or by or in the right of any other enterprise which
such directors and officers served in any capacity at the request of the corporation, by reason of
the fact that such person acted in any of the capacities set forth above, if such director or
officer (i) acted in good faith and in a manner which he or she reasonably believed to be in or not
opposed to the best interests of the corporation, and (ii) in criminal actions or proceedings, had
no reasonable cause to believe that his or her conduct was unlawful. A corporation is required to
indemnify against reasonable expenses (including attorneys' fees) incurred by any director or
officer who successfully defends any such action. The DGCL also provides for indemnification of
officers and directors in actions by or in the right of the corporation, subject to certain
exceptions. Indemnification provided by these provisions of the DGCL is not exclusive of any other
rights to which a director or officer may be entitled. The foregoing statements are subject to the
detailed provisions of the DGCL.
Article VII of the Registrant's By-laws provides that the Registrant shall indemnify any
officer or director of the Registrant to the extent, in the manner, and subject to compliance with
the applicable standards of conduct, provided by Section 145 of the DGCL. It also provides that
the Registrant shall indemnify and advance expenses to the directors and officers of the Registrant
to the fullest extent permitted by law.
The Registrant maintains directors' and officers' liability insurance covering all directors
and officers of the Registrant against claims arising out of the performance of their duties.

Exhibits
.
Reference is made to the Exhibit Index on page E-1 of this Registration Statement, which
Exhibit Index is incorporated herein by reference.
Item 9.
Undertakings
.
A.
The 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 the registration statement (or the most recent
post-effective amendment thereof) which, individually or in the aggregate,
represents a fundamental change in the information set forth in the
registration statement; and
II-2
Table of Contents
(iii)
to include any material information with respect to the plan
of distribution not previously disclosed in the registration statement or any
material change to such information in the registration statement;
provided, however, that paragraphs A(1)(i) and A(1)(ii) do 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 Commission by the
Registrant pursuant to Section 13 or 15(d) of the 1934 Act that are incorporated by
reference in the 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.
(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.
(4)
That, for the purpose of determining liability under the 1933
Act to any purchaser:
(i)
if the Registrant is relying on Rule 430B:
(A)
each prospectus filed by the Registrant pursuant to Rule 424(b)(3) shall
be deemed to be part of the registration statement as of the date the filed
prospectus was deemed part of and included in the registration statement;
and
(B)
each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5),
or (b)(7) as part of the registration statement in reliance on Rule 430B
relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x)
for the purpose of providing the information required by section 10(a) of
the 1933 Act shall be deemed to be part of and included in the registration
statement as of the earlier of the date such form of prospectus is first
used after effectiveness or the date of the first contract sale of
securities in the offering described in the prospectus. As provided in Rule
430B, for liability purposes of the issuer and any person that is at that
date an underwriter, such date shall be deemed to be a new effective date of
the registration statement relating to the securities in the registration
statement to which that prospectus relates, and the offering of such
securities at that time shall be deemed to be the initial
bona fide
offering
thereof; provided, however, that no statement made in a registration
statement or prospectus that is that is a part of the registration statement
or made in a document incorporated by reference or deemed incorporate by
reference into the registration statement or prospectus that is part of the
registration statement will, as to a purchaser with a time of contract of
sale prior to such effective date, supersede or modify any statement that
was made in the registration statement or prospectus that was part of the
registration statement or made in any such document immediately prior to
such effective date, or;
(ii)
if the Registrant is subject to Rule 430C, each prospectus filed
pursuant to Rule 424(b) as part of a registration statement relating to an
offering, other than registration statements relying on Rule 430B or other
than prospectuses filed in reliance on Rule 430A, shall be deemed to be part
of and included in the registration statement as of the date it is
II-3
Table of Contents
first used after effectiveness; provided, however, that no statement made in
the registration statement or prospectus that is part of the registration
statement or made in a document incorporated or deemed incorporated by
reference into the registration statement will, as to the purchaser with a
time of contract of sale prior to such first use, supersede or modify any
statement that was made in the registration statement or prospectus that was
part of the registration statement or made in any such document immediately
prior to such date of first use.
(5) That, for the purpose of determining liability of the Registrant under the 1933
Act to any purchaser in the initial distribution of the securities:
The undersigned Registrant undertakes that in a primary offering of securities of
the undersigned Registrant pursuant to this registration statement, regardless of
the underwriting method used to sell the securities to the purchaser, if the
securities are offered or sold to such purchaser by means of any of the following
communications, the undersigned Registrant will be a seller to the purchaser and
will be considered to offer or sell such securities to such purchaser:
(i) any preliminary prospectus or prospectus of the undersigned Registrant
relating to the offering required to be filed pursuant to Rule 424;
(ii) any free writing prospectus relating to the offering prepared by or on
behalf of the undersigned Registrant or used or referred to by the
undersigned Registrant;
(iii) the portion of any other free writing prospectus relating to the
offering containing material information about the undersigned Registrant or
its securities provided by or on behalf of the undersigned Registrant; and
(iv) any other communication that is an offer in the offering made by the
undersigned Registrant to the purchaser.
(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 15(d) of the 1934 Act
(and, where applicable, each filing of an employee benefit plan's annual report
pursuant to Section 15(d) of the 1934 Act) that is incorporated by reference in
the 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 and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Commission such indemnification is
against public policy as expressed in the 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
II-4
Table of Contents
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 policy as expressed in the Act and will be governed by the final
adjudication of such issue.
