<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Section&nbsp;102(b) of the Delaware General Corporation Law authorizes 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 or alleged breach of the
director&#146;s &#147;duty of care.&#148; While this statute does not change directors&#146; duty of care, it enables
corporations to limit available relief to equitable remedies such as injunction or rescission. The
statute has no effect on a director&#146;s duty of loyalty or liability for acts or omissions not in
good faith or involving intentional misconduct or knowing violations of law, illegal payment of
dividends or stock redemptions or repurchases, or for any transaction from which the director
derives an improper personal benefit. As permitted by the statute, the Registrant has adopted
provisions in its certificate of incorporation that eliminate to the fullest extent permissible
under Delaware law the personal liability of its directors to the Registrant and its stockholders
for monetary damages for breach or alleged breach of their duty of care. The Registrant&#146;s
certificate of incorporation eliminates the personal liability of each of its directors for
monetary damages resulting from any breach of his fiduciary duty as a director, except for
liability:

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)&nbsp;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) above shall not apply if the information required to be included in
a post-effective amendment by those clauses is contained in periodic reports filed with or
furnished to the Commission by the Registrant pursuant to Section&nbsp;13 or Section 15(d) of the
1934 Act that are incorporated by reference into this Registration Statement; (2)&nbsp;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)&nbsp;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.

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.

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&nbsp;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. 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.

Item 5. Interests of named experts and counsel
Not applicable.
Item 6. Indemnification of directors and officers
Section 102(b) of the Delaware General Corporation Law authorizes 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 or alleged breach of the
director's "duty of care." While this statute does not change directors' duty of care, it enables
corporations to limit available relief to equitable remedies such as injunction or rescission. The
statute has no effect on a director's duty of loyalty or liability for acts or omissions not in
good faith or involving intentional misconduct or knowing violations of law, illegal payment of
dividends or stock redemptions or repurchases, or for any transaction from which the director
derives an improper personal benefit. As permitted by the statute, the Registrant has adopted
provisions in its certificate of incorporation that eliminate to the fullest extent permissible
under Delaware law the personal liability of its directors to the Registrant and its stockholders
for monetary damages for breach or alleged breach of their duty of care. The Registrant's
certificate of incorporation eliminates the personal liability of each of its directors for
monetary damages resulting from any breach of his fiduciary duty as a director, except for
liability:
•
for any breach of the director's duty of loyalty to the Registrant or its
stockholders;
•
for acts or omissions not in good faith or that involve intentional
misconduct or a knowing violation of law;
•
under Section 174 of the Delaware General Corporation Law regarding unlawful
dividends, stock purchases and redemptions; or
•
for any transaction from which the director derived an improper personal
benefit.

Section 145 of the Delaware General Corporation Law provides that a corporation may indemnify
directors and officers as well as other individuals against expenses, 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 to the
Registrant. 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.
The Registrant's bylaws provide that:
•
the Registrant is required to indemnify its directors and officers, subject to
limited exceptions in which such directors or officers are adjudged to be liable to
the Registrant;
•
the Registrant is required to advance expenses, as incurred, to its directors
and officers in connection with a legal proceeding to the fullest extent permitted
by the Delaware General Corporation Law, subject to limited exceptions; and
•
the rights conferred in the bylaws are not exclusive.
In addition, the Registrant has entered or will enter in the future into indemnity agreements with
each of its current directors and officers. These agreements provide for the indemnification of the
Registrant's officers and directors for all expenses and liabilities incurred in connection with
any action or proceeding brought against them by reason of the fact that they are or were agents of
the Registrant. At present, there is no pending litigation or proceeding involving a director,
officer or employee of the Registrant regarding which indemnification is sought, nor is the
Registrant aware of any threatened litigation that may result in claims for indemnification.
The Registrant also has obtained directors' and officers' insurance to cover its directors,
officers and some of the Registrant's employees for liabilities, including coverage for public
securities matters.
Reference is made to the underwriting agreement filed as Exhibit 1.1 to Registrant's Registration
Statement on Form S-1 (Registration No. 333-141884), as amended, pursuant to which the underwriters
have agreed to indemnify the Registrant's officers and directors against certain liabilities under
the 1933 Act.

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, as amended (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) above shall not apply if the information required to be included in
a post-effective amendment by those clauses is contained in periodic reports filed with or
furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the
1934 Act that are incorporated by reference into 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 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. 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.
