<DIV align="left" style="font-size: 10pt; margin-top: 12pt">Item&nbsp;6. Indemnification of Directors and Officers.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Section&nbsp;145 of the Delaware General Corporation Law (the &#147;DGCL&#148;) permits the indemnification
by a Delaware corporation of its directors, officers, employees, and other agents against expenses
(including attorneys&#146; fees), judgments, fines, and amounts paid in settlement in connection with
specified actions, suits or proceedings, whether civil, criminal, administrative, or investigative
(other than derivative actions which are by or in the right of the corporation) if they acted in
good faith and in a manner they reasonably believed to be in or not opposed to the best interests
of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause
to believe their conduct was illegal. In the case of derivative actions, indemnification only
extends to expenses (including attorneys&#146; fees) incurred in connection with defense or settlement
of such an action and requires court approval before there can be any indemnification where the
person seeking indemnification has been found liable to the corporation.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company&#146;s Bylaws provide that it will indemnify to the full extent permitted by, and in
the manner permissible under, the laws of the State of Delaware any person made, or threatened to
be made, a party to an action or proceeding, whether criminal, civil, administrative or
investigative, by reason of the fact that he, his testator or intestate is or was a director or
officer of the Company or any predecessor of the Company, or served any other enterprise as a
director or officer at the request of the Company or any predecessor of the Company. The Company
maintains liability insurance on behalf of its officers and directors.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Section&nbsp;102(b)(7) of the DGCL permits a corporation, in its certificate of incorporation, to
limit or eliminate, subject to certain statutory limitations, the liability of directors to the
corporation or its stockholders for monetary damages for breaches of fiduciary duty, except for
liability (a)&nbsp;for any breach of the director&#146;s duty of loyalty to the corporation or its
stockholders, (b)&nbsp;for acts or omissions not in good faith or which involve intentional misconduct
or a knowing violation of law, (c)&nbsp;for any willful or negligent payment of an unlawful dividend,
stock purchase or redemption, or (d)&nbsp;for any transaction from which the director derived an
improper personal benefit. The Company&#146;s Certificate of Incorporation provides that the personal
liability of the Company&#146;s directors is eliminated to the fullest extent permitted by Section
102(b)(7) of the DGCL.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2)&nbsp;That, for the purpose of determining any liability under the Securities Act of 1933, each

</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)&nbsp;The undersigned registrant hereby undertakes that, for purposes of determining any
liability under the Securities Act of 1933, each filing of the registrant&#146;s annual report pursuant
to section 13(a) or section 15(d) of the Securities Exchange Act of 1934 (and, where applicable,
each filing of an employee benefit plan&#146;s annual report pursuant to section 15(d) of the Securities
Exchange Act of 1934) that is incorporated by reference in the registration statement shall be
deemed to be a new registration statement relating to the securities offered herein, and the
offering of such securities at that time shall be deemed to be the initial <I>bona fide </I>offering
thereof.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)&nbsp;Insofar as indemnification for liabilities arising under the Securities Act of 1933 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
Securities and Exchange 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
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 Act and
will be governed by the final adjudication of such issue.

EXPLANATORY NOTE
Pursuant to General Instruction E to Form S-8, the contents of the Registrant's Registration
Statement on Form S-8 (Registration No. 333-107872), are hereby incorporated herein by reference,
except for Items 6, 8 and 9, which are being updated by this registration statement.
INFORMATION REQUIRED IN THE REGISTRATION STATEMENT
Item 6. Indemnification of Directors and Officers.
Section 145 of the Delaware General Corporation Law (the "DGCL") permits the indemnification
by a Delaware corporation of its directors, officers, employees, and other agents against expenses
(including attorneys' fees), judgments, fines, and amounts paid in settlement in connection with
specified actions, suits or proceedings, whether civil, criminal, administrative, or investigative
(other than derivative actions which are by or in the right of the corporation) if they acted in
good faith and in a manner they reasonably believed to be in or not opposed to the best interests
of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause
to believe their conduct was illegal. In the case of derivative actions, indemnification only
extends to expenses (including attorneys' fees) incurred in connection with defense or settlement
of such an action and requires court approval before there can be any indemnification where the
person seeking indemnification has been found liable to the corporation.
The Company's Bylaws provide that it will indemnify to the full extent permitted by, and in
the manner permissible under, the laws of the State of Delaware any person made, or threatened to
be made, a party to an action or proceeding, whether criminal, civil, administrative or
investigative, by reason of the fact that he, his testator or intestate is or was a director or
officer of the Company or any predecessor of the Company, or served any other enterprise as a
director or officer at the request of the Company or any predecessor of the Company. The Company
maintains liability insurance on behalf of its officers and directors.
Section 102(b)(7) of the DGCL permits a corporation, in its certificate of incorporation, to
limit or eliminate, subject to certain statutory limitations, the liability of directors to the
corporation or its stockholders for monetary damages for breaches of fiduciary duty, except for
liability (a) for any breach of the director's duty of loyalty to the corporation or its
stockholders, (b) for acts or omissions not in good faith or which involve intentional misconduct
or a knowing violation of law, (c) for any willful or negligent payment of an unlawful dividend,
stock purchase or redemption, or (d) for any transaction from which the director derived an
improper personal benefit. The Company's Certificate of Incorporation provides that the personal
liability of the Company's directors is eliminated to the fullest extent permitted by Section
102(b)(7) of the DGCL.

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 Securities Act of 1933;
(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, represent a fundamental change in the information set forth in the registration
statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered
(if the total dollar value of securities offered would not exceed that which was registered) and
any deviation from the low or high end of the estimated maximum offering range may be reflected in
the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the
changes in volume and price represent no more than a 20% change in the maximum aggregate offering
price set forth in the "Calculation of Registration Fee" table in the effective registration
statement;
(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) of this section 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 section 15(d) of the Securities Exchange Act of 1934 that are incorporated by
reference in this registration statement.
Table of Contents
(2) That, for the purpose of determining any liability under the Securities Act of 1933, 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.
(b) The undersigned registrant hereby undertakes that, for purposes of determining any
liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant
to section 13(a) or section 15(d) of the Securities Exchange Act of 1934 (and, where applicable,
each filing of an employee benefit plan's annual report pursuant to section 15(d) of the Securities
Exchange Act of 1934) that is incorporated by reference in the registration statement shall be
deemed to be a new registration statement relating to the securities offered herein, 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 Securities Act of 1933 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
Securities and Exchange 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
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 Act and
will be governed by the final adjudication of such issue.
