</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company is incorporated in Delaware. Under Section&nbsp;145 of the General Corporation Law of
the State of Delaware, a Delaware corporation has the power to indemnify its directors, officers,
employees and agents from expenses (including attorney&#146;s fees), judgments, fines, and amounts paid
in settlement actually and reasonably incurred in connection with a threatened, pending, or
completed action, suit or proceeding, whether civil, criminal, administrative, or investigative, in
which such person is involved by reason of the fact such person were or are directors, officers,
employees or agents of the Company, provided that such person acted in good faith and in a manner
that such person reasonably believed to be in the best interests of the corporation and, in the
case of a criminal proceeding, such person had no reasonable cause to believe his or her conduct
was unlawful. Such person may not be indemnified if the person has been adjudged liable to the
corporation in the performance of such person&#146;s duties to the corporation, unless the Court of
Chancery or the court in which such action or suit was brought determines that, in view of the
circumstances of the case, such person is fairly and reasonably entitled to indemnity. To the
extent that such person has been successful on the merits or otherwise in defense of any
proceeding, the General Corporate Law of the State of Delaware provides that such person shall be
indemnified against expenses (including attorney&#146;s fees) reasonably and actually incurred. The
Certificate of Incorporation and the By-laws of the Company provide for indemnification of
directors and officers to the fullest extent permitted by the General Corporation Law of the State
of Delaware.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Section&nbsp;102(b)(7) of the General Corporation Law of the State of Delaware provides that a
certificate of incorporation may contain a provision eliminating the personal liability of a
director to the corporation or its stockholders for monetary damages for breach of fiduciary duty
as a director provided that such provision shall not eliminate or limit the liability of a director
(i)&nbsp;for any breach of the director&#146;s duty of loyalty to the corporation or its stockholders, (ii)
for acts or omissions not in good faith or which involve intentional misconduct or a knowing
violation of law, (iii)&nbsp;for unlawful payment of dividends or stock redemption, or (iv)&nbsp;for any
transaction from which the director derived an improper personal benefit. The Company&#146;s
Certificate of Incorporation contains such a provision.

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

question whether such indemnification by it is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such issue.

and 15(d) of the Securities and Exchange Act of 1934, as amended (the "Exchange Act"), prior to the

Item 6. Indemnification of Directors and Officers.
The Company is incorporated in Delaware. Under Section 145 of the General Corporation Law of
the State of Delaware, a Delaware corporation has the power to indemnify its directors, officers,
employees and agents from expenses (including attorney's fees), judgments, fines, and amounts paid
in settlement actually and reasonably incurred in connection with a threatened, pending, or
completed action, suit or proceeding, whether civil, criminal, administrative, or investigative, in
which such person is involved by reason of the fact such person were or are directors, officers,
employees or agents of the Company, provided that such person acted in good faith and in a manner
that such person reasonably believed to be in the best interests of the corporation and, in the
case of a criminal proceeding, such person had no reasonable cause to believe his or her conduct
was unlawful. Such person may not be indemnified if the person has been adjudged liable to the
corporation in the performance of such person's duties to the corporation, unless the Court of
Chancery or the court in which such action or suit was brought determines that, in view of the
circumstances of the case, such person is fairly and reasonably entitled to indemnity. To the
extent that such person has been successful on the merits or otherwise in defense of any
proceeding, the General Corporate Law of the State of Delaware provides that such person shall be
indemnified against expenses (including attorney's fees) reasonably and actually incurred. The
Certificate of Incorporation and the By-laws of the Company provide for indemnification of
directors and officers to the fullest extent permitted by the General Corporation Law of the State
of Delaware.
Section 102(b)(7) of the General Corporation Law of the State of Delaware provides that a
certificate of incorporation may contain a provision eliminating the personal liability of a
director to the corporation or its stockholders for monetary damages for breach of fiduciary duty
as a director provided that such provision shall not eliminate or limit the liability of a director
(i) for any breach of the director's duty of loyalty to the corporation or its stockholders, (ii)
for acts or omissions not in good faith or which involve intentional misconduct or a knowing
violation of law, (iii) for unlawful payment of dividends or stock redemption, or (iv) for any
transaction from which the director derived an improper personal benefit. The Company's
Certificate of Incorporation contains such a provision.
Item 7. Exemption from Registration Claimed.
Not applicable.

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 (the "Securities 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 — notwithstanding the foregoing, any increase or decrease in volume of
securities offered (if the 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 in the "Calculation of Registration Fee" table 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 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 by the Registrant pursuant to Section 13 or 15(d) of the
Exchange Act that are incorporated by reference in this Registration Statement.
(2)     That, for the purpose of determining any liability under the Securities Act, each such
post-effective amendment shall be deemed to be a new Registration Statement relating to the
securities

Table of Contents
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 Exchange Act (and, where applicable, each filing of an employee
benefit plan's annual report pursuant to section 15(d) of the Exchange 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 Securities 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 Securities and
Exchange Commission such indemnification is against public policy as expressed in the Securities
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 Securities
Act and will be governed by the final adjudication of such issue.
