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

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company&#146;s certificate of incorporation limits the liability of the Company&#146;s directors to
the fullest extent permitted by the General Corporation Law of the State of Delaware (the &#147;DGCL&#148;).
The DCGL provides that a corporation may limit the personal liability of its directors for monetary
damages for breach of that individual&#146;s fiduciary duties as a director except for liability for any
of the following: (a)&nbsp;a breach of the director&#146;s duty of loyalty to the corporation or its
stockholders; (b)&nbsp;any act or omission not in good faith or that involves intentional misconduct or
a knowing violation of the law; (c)&nbsp;certain unlawful payments of dividends or unlawful stock
repurchases or redemptions; or (d)&nbsp;any transaction from which the director derived an improper
personal benefit. This limitation of liability does not apply to liabilities arising under federal
securities laws and does not affect the availability of equitable remedies such as injunctive
relief or rescission.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Section&nbsp;145 of the DGCL generally provides that a corporation may indemnify directors and
officers, as well as other employees and individuals, against attorneys&#146; fees and other judgments,
fines and amounts paid in settlement actually and reasonably incurred by such person in connection
with any threatened, pending or completed action, suit or proceeding in which such person was or is
a party or is threatened to be made a party by reason of such person being or having been a
director, officer, employee or agent of the corporation. The DCGL provides that Section&nbsp;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.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company&#146;s certificate of incorporation provides that the Company is required to indemnify
its directors and officers to the fullest extent permitted or required by the DGCL, although,
except with respect to certain actions, suits or proceedings to enforce rights to indemnification,
a director or officer will only be indemnified with respect to any action, suit or proceeding such
person initiated to the extent such action, suit or proceeding was authorized by the Company&#146;s
Board of Directors. The Company&#146;s certificate of incorporation also requires the Company to
advance expenses incurred by a director or officer in connection with the defense of any action,
suit or proceeding arising out of that person&#146;s status or service as director or officer of the
Company or as director, officer, employee or agent of another enterprise, if serving at the
Company&#146;s request. In addition, the Company&#146;s certificate of incorporation permits the Company to
secure insurance to protect itself and any director, officer, employee or agent of the Company or
any other corporation, partnership, joint venture, trust or other enterprise against any expense,
liability or loss.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In addition, the Company has entered into indemnification agreements with each of its
directors and executive officers containing provisions that obligate the Company to, among other
things:

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 Securities Act of 1933
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 Securities
Act of 1933 and will be governed by the final adjudication of such issue.

Item 6. Indemnification of Directors and Officers.
The Company's certificate of incorporation limits the liability of the Company's directors to
the fullest extent permitted by the General Corporation Law of the State of Delaware (the "DGCL").
The DCGL provides that a corporation may limit the personal liability of its directors for monetary
damages for breach of that individual's fiduciary duties as a director except for liability for any
of the following: (a) a breach of the director's duty of loyalty to the corporation or its
stockholders; (b) any act or omission not in good faith or that involves intentional misconduct or
a knowing violation of the law; (c) certain unlawful payments of dividends or unlawful stock
repurchases or redemptions; or (d) any transaction from which the director derived an improper
personal benefit. This limitation of liability does not apply to liabilities arising under federal
securities laws and does not affect the availability of equitable remedies such as injunctive
relief or rescission.
Section 145 of the DGCL generally provides that a corporation may indemnify directors and
officers, as well as other employees and individuals, against attorneys' fees and other judgments,
fines and amounts paid in settlement actually and reasonably incurred by such person in connection
with any threatened, pending or completed action, suit or proceeding in which such person was or is
a party or is threatened to be made a party by reason of such person being or having been a
director, officer, employee or agent of the corporation. The DCGL 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.
The Company's certificate of incorporation provides that the Company is required to indemnify
its directors and officers to the fullest extent permitted or required by the DGCL, although,
except with respect to certain actions, suits or proceedings to enforce rights to indemnification,
a director or officer will only be indemnified with respect to any action, suit or proceeding such
person initiated to the extent such action, suit or proceeding was authorized by the Company's
Board of Directors. The Company's certificate of incorporation also requires the Company to
advance expenses incurred by a director or officer in connection with the defense of any action,
suit or proceeding arising out of that person's status or service as director or officer of the
Company or as director, officer, employee or agent of another enterprise, if serving at the
Company's request. In addition, the Company's certificate of incorporation permits the Company to
secure insurance to protect itself and any director, officer, employee or agent of the Company or
any other corporation, partnership, joint venture, trust or other enterprise against any expense,
liability or loss.
In addition, the Company has entered into indemnification agreements with each of its
directors and executive officers containing provisions that obligate the Company to, among other
things:
•
indemnify, defend and hold harmless the director or officer to the fullest extent
permitted or required by Delaware law, except that, subject to certain exceptions, the
director or officer will be indemnified with respect to a claim initiated by such
director or officer against the Company or any other director or officer of the Company
only if the Company has joined in or consented to the initiation of such claim;

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 a 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; and
4
(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 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
periodic reports filed with or furnished to the Commission by the registrant pursuant to
Section 13 or 15(d) of the Securities Exchange Act of 1934 that are incorporated by
reference in this registration statement.
(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.
(4) That, for the purpose of determining liability of the registrant under the
Securities Act of 1933 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 Securities Act of 1933, each filing of the registrant's annual report pursuant
to Section 13(a) or 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 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 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
Commission such indemnification is against public policy as expressed in the Securities Act of 1933
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 Securities
Act of 1933 and will be governed by the final adjudication of such issue.
