Corporation Law of the State of Delaware provides generally that a corporation may indemnify any
person who was or is a party to or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative, or investigative in
nature, by reason of the fact that he is or was a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise, against expenses (including
attorneys&#146; fees) and, in a proceeding not by or in the right of the corporation, judgments, fines,
and amounts paid in settlement, actually and reasonably incurred by him in connection with such
suit or proceeding, if he acted in good faith and in a manner 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 reason to believe his conduct was unlawful. Delaware law further provides that a corporation may
not indemnify any person against expenses incurred in connection with an action by or in the right
of the corporation if such person shall have been adjudged to be liable in the performance of his
duty to the corporation unless and only to the extent that the court in which such action or suit
was brought shall determine that, despite the adjudication of liability but in the view of all the
circumstances of the case, such person is fairly and reasonably entitled to indemnity for the
expenses which such court shall deem proper. The Company&#146;s bylaws provide that the corporation
shall indemnify an officer or director against liability incurred by such person as authorized
under the General Corporation Law of the State of Delaware. In addition, the directors and officers
of the Company have entered into specific agreements which provide for indemnification of such
persons by the Company under certain circumstances.
</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 permits 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 of
fiduciary duty as a director, except for liability (i)&nbsp;for any breach of the director&#146;s duty of
loyalty to the corporation or its stockholders, (ii)&nbsp;for acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of law, (iii)&nbsp;for unlawful payments of
dividends or unlawful stock repurchases, redemptions or other distributions, or (iv)&nbsp;for any
transaction from which the director derived an improper personal benefit. The Company&#146;s certificate
of incorporation provides for limitation of liability for beach of fiduciary duty to the fullest
extent permitted by the General Corporation Law of the State of Delaware.

Rule 424(b) if, in the aggregate, the changes in volume and price represent no more

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.

Item 4. Description of Securities.
Not applicable.
Item 5. Interests of Named Experts and Counsel.
Not applicable.
Item 6. Indemnification of Directors and Officers.
The Company is a corporation organized under Delaware law. Section 145 of the General
Corporation Law of the State of Delaware provides generally that a corporation may indemnify any
person who was or is a party to or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative, or investigative in
nature, by reason of the fact that he is or was a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise, against expenses (including
attorneys' fees) and, in a proceeding not by or in the right of the corporation, judgments, fines,
and amounts paid in settlement, actually and reasonably incurred by him in connection with such
suit or proceeding, if he acted in good faith and in a manner 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 reason to believe his conduct was unlawful. Delaware law further provides that a corporation may
not indemnify any person against expenses incurred in connection with an action by or in the right
of the corporation if such person shall have been adjudged to be liable in the performance of his
duty to the corporation unless and only to the extent that the court in which such action or suit
was brought shall determine that, despite the adjudication of liability but in the view of all the
circumstances of the case, such person is fairly and reasonably entitled to indemnity for the
expenses which such court shall deem proper. The Company's bylaws provide that the corporation
shall indemnify an officer or director against liability incurred by such person as authorized
under the General Corporation Law of the State of Delaware. In addition, the directors and officers
of the Company have entered into specific agreements which provide for indemnification of such
persons by the Company under certain circumstances.
Section 102(b)(7) of the General Corporation Law of the State of Delaware permits 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 of
fiduciary duty as a director, except for liability (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 payments of
dividends or unlawful stock repurchases, redemptions or other distributions, or (iv) for any
transaction from which the director derived an improper personal benefit. The Company's certificate
of incorporation provides for limitation of liability for beach of fiduciary duty to the fullest
extent permitted by the General Corporation Law of the State of Delaware.

Item 9. Undertakings.
(a) The undersigned Registrant hereby undertakes:
(1) To file, during any period in which offers or sales are being made of the
securities registered hereby, a post-effective amendment to this Registration Statement:
(i) To include any prospectus required by Section 10(a)(3) of 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
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;
3
Table of Contents
(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 the undertakings set forth in paragraphs (a)(1)(i) and (a)(1)(ii)
above 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 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 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, 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 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 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.
