threatened, pending or completed action, suit or proceeding,
whether civil, criminal, administrative or investigative (other
than an action by or in the right of the corporation) by reason
of the fact that such person is or was a director, officer,
employee or agent of the corporation, or is or was serving at

or agent of another corporation or enterprise, against expenses
(including attorneys&#146; fees), judgments, fines and amounts
paid in settlement actually and reasonably incurred by such
person in connection with such action, suit or proceeding if he
or she acted in good faith and in a manner he or she 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 cause to believe his or her conduct was
unlawful.

Section&nbsp;145(b) of the Delaware General Corporation Law
provides that a Delaware corporation may indemnify any person
who was or is a party or is threatened to be made a party to any
threatened, pending or completed action or suit by or in the
right of the corporation to procure a judgment in its favor by
reason of the fact that such person acted in any of the

person in connection with the defense or settlement of such
action or suit if he or she acted under similar standards,

claim, issue or matter as to which such person shall have been
adjudged to be liable 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 view of all the circumstances of the case, such person is
fairly and reasonably entitled to be indemnified for such
expenses which the court shall deem proper.

subsections (a)&nbsp;and (b)&nbsp;or in the defense of any
claim, issue or matter therein, such person shall be indemnified

indemnified party may be entitled; and (iii)&nbsp;the
corporation may purchase and maintain insurance on behalf of any
present or former director, officer, employee or agent of the
corporation or any person who at the request of the corporation
was serving in such capacity for another entity against any
liability asserted against such person and incurred by him or
her in any such capacity or arising out of his or her status as
such, whether or not the corporation would have the power to
indemnify him or her against such liabilities under

As permitted by Section&nbsp;102(b)(7) of the Delaware General
Corporation Law, the Registrant&#146;s Restated Certificate of
Incorporation provides that a director shall not be liable to
the Registrant or its stockholders for monetary damages for
breach of fiduciary duty as a director. However, such provision
does not eliminate or limit the liability of a director for acts
or omissions not in good faith or for breaching his or her duty
of loyalty, engaging in intentional misconduct or knowingly
violating a law, paying a dividend or approving a stock
repurchase that was illegal, or obtaining an improper personal
benefit. In addition, the Registrant&#146;s Restated Certificate
of Incorporation and bylaws contain provisions requiring
indemnification of directors and executive officers of the
Registrant to the fullest extent authorized by the Delaware
General Corporation Law, and permitting the indemnification of
its other employees and agents (and employees and agents of its
subsidiaries and affiliates) to the fullest extent authorized
under the Delaware General Corporation Law. The Registrant has
entered into indemnification agreements with each of its
directors and each of its officers at the senior vice

Under the provisions of the Registrant&#146;s Restated
Certificate of Incorporation, expenses incurred by a director or
executive officer in defending a civil or criminal suit or
proceeding shall be paid by the Registrant in advance of the
final disposition of such action, suit or proceeding upon
receipt of an undertaking by or on behalf of the person seeking
indemnification to repay such amounts if it is ultimately
determined that he or she is not entitled to be indemnified. The
Registrant&#146;s Restated Certificate of Incorporation
currently authorizes, but does not require, advancement of
expenses to employees and agents of the Registrant on the same
conditions that apply to directors and executive officers of the
Registrant. The rights to indemnification set forth in the
Registrant&#146;s Restated Certificate of Incorporation and
bylaws are not exclusive of any provisions with respect thereto
in other contracts or agreements between the Registrant and any
officer, director, employee or agent of the Registrant,
including the indemnification agreements described above.

The Registrant may, to the fullest extent permitted by the

by insurance policies maintained by the Registrant against
certain liabilities for actions taken in their capacities as
such, including liabilities under the Securities Act.

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 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.

The following documents previously filed with the Securities and

incorporated by reference into this Registration Statement:
(a) The Registrant's most recent Annual Report
    pursuant to Section 13(a) or 15(d) of the Securities
    Exchange Act of 1934, as amended (the "Exchange Act"),
    or latest prospectus filed pursuant to Rule 424(b) under

Item 6.
Indemnification of Directors and Officers.
Section 145(a) of the Delaware General Corporation Law
provides that a Delaware corporation may indemnify any person
who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding,
whether civil, criminal, administrative or investigative (other
than an action by or in the right of the corporation) by reason
of the fact that such person is or was a director, officer,
employee or agent of the corporation, or is or was serving at
the request of the corporation as a director, officer, employee
or agent of another corporation or enterprise, against expenses
(including attorneys' fees), judgments, fines and amounts
paid in settlement actually and reasonably incurred by such
person in connection with such action, suit or proceeding if he
or she acted in good faith and in a manner he or she 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 cause to believe his or her conduct was
unlawful.
Section 145(b) of the Delaware General Corporation Law
provides that a Delaware corporation may indemnify any person
who was or is a party or is threatened to be made a party to any
threatened, pending or completed action or suit by or in the
right of the corporation to procure a judgment in its favor by
reason of the fact that such person acted in any of the
capacities set forth above, against expenses (including
attorneys' fees) actually and reasonably incurred by such
person in connection with the defense or settlement of such
action or suit if he or she acted under similar standards,
except that no indemnification may be made in respect of any
claim, issue or matter as to which such person shall have been
adjudged to be liable 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 view of all the circumstances of the case, such person is
fairly and reasonably entitled to be indemnified for such
expenses which the court shall deem proper.
Section 145 of the Delaware General Corporation Law further
provides that: (i) to the extent that a former or present
director or officer of a corporation has been successful in the
defense of any action, suit or proceeding referred to in
subsections (a) and (b) or in the defense of any
claim, issue or matter therein, such person shall be indemnified
against expenses (including attorneys' fees) actually and
reasonably incurred by him or her in connection therewith;
(ii) indemnification provided for by Section 145 shall
not be deemed exclusive of any other rights to which the
indemnified party may be entitled; and (iii) the
corporation may purchase and maintain insurance on behalf of any
present or former director, officer, employee or agent of the
corporation or any person who at the request of the corporation
was serving in such capacity for another entity against any
liability asserted against such person and incurred by him or
her in any such capacity or arising out of his or her status as
such, whether or not the corporation would have the power to
indemnify him or her against such liabilities under
Section 145.
As permitted by Section 102(b)(7) of the Delaware General
Corporation Law, the Registrant's Restated Certificate of
Incorporation provides that a director shall not be liable to
the Registrant or its stockholders for monetary damages for
breach of fiduciary duty as a director. However, such provision
does not eliminate or limit the liability of a director for acts
or omissions not in good faith or for breaching his or her duty
of loyalty, engaging in intentional misconduct or knowingly
violating a law, paying a dividend or approving a stock
repurchase that was illegal, or obtaining an improper personal
benefit. In addition, the Registrant's Restated Certificate
of Incorporation and bylaws contain provisions requiring
indemnification of directors and executive officers of the
Registrant to the fullest extent authorized by the Delaware
General Corporation Law, and permitting the indemnification of
its other employees and agents (and employees and agents of its
subsidiaries and affiliates) to the fullest extent authorized
under the Delaware General Corporation Law. The Registrant has
entered into indemnification agreements with each of its
directors and each of its officers at the senior vice
2
president level and above. These agreements provide for
indemnification to the fullest extent permitted by the Delaware
General Corporation Law.
Under the provisions of the Registrant's Restated
Certificate of Incorporation, expenses incurred by a director or
executive officer in defending a civil or criminal suit or
proceeding shall be paid by the Registrant in advance of the
final disposition of such action, suit or proceeding upon
receipt of an undertaking by or on behalf of the person seeking
indemnification to repay such amounts if it is ultimately
determined that he or she is not entitled to be indemnified. The
Registrant's Restated Certificate of Incorporation
currently authorizes, but does not require, advancement of
expenses to employees and agents of the Registrant on the same
conditions that apply to directors and executive officers of the
Registrant. The rights to indemnification set forth in the
Registrant's Restated Certificate of Incorporation and
bylaws are not exclusive of any provisions with respect thereto
in other contracts or agreements between the Registrant and any
officer, director, employee or agent of the Registrant,
including the indemnification agreements described above.
The Registrant may, to the fullest extent permitted by the
Delaware General Corporation Law, purchase and maintain
insurance on behalf of any officer, director, employee or agent
against any liability that may be asserted against such person.
All of the Registrant's directors and officers are covered
by insurance policies maintained by the Registrant against
certain liabilities for actions taken in their capacities as
such, including liabilities under the Securities Act.

Item 9.
Undertakings.
1. The undersigned Registrant hereby undertakes:
(a) 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;
(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
3
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 percent (20%) change in
    the maximum aggregate offering price set forth in the
    "Calculation of Registration Fee" table in the
    effective 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 (1)(a)(i) and
    (1)(a)(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
    Section 15(d) of the Exchange Act that are incorporated by
    reference in this Registration Statement;
(b) 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; and
(c) 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.
2. 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
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.
3. 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 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.
