units and performance shares and participates in the Company's employee benefit
plans.

ITEM 6.       INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         Section 145(a) of the General Corporation Law of the State of Delaware
("Delaware Corporation Law") provides, in general, that a corporation shall have
the power to 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), because the person is or was a director
or officer of the corporation. Such indemnity may be against expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by the person in connection with such action, suit or
proceeding, if the person acted in good faith and in a manner the person
reasonably believed to be in or not opposed to the best interests of the
corporation and if, with respect to any criminal action or proceeding, the
person did not have reasonable cause to believe the person's conduct was
unlawful.

         Section 145(b) of the Delaware Corporation Law provides, in general,
that a corporation shall have the power to 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 because the person is or was a director or officer of the
corporation, against any expenses (including attorneys' fees) actually and
reasonably incurred by the person in connection with the defense

<PAGE>

or settlement of such action or suit if the person acted in good faith and in a
manner the person reasonably believed to be in or not opposed to the best
interests of the corporation, except that no indemnification shall 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 of Chancery or the court in which such action or suit was brought shall
determine upon application that, despite the adjudication of liability but in
view of all the circumstances of the case, such person is fairly and reasonably
entitled to indemnity for such expenses which the Court of Chancery or such
other court shall deem proper.

         Section 145(g) of the Delaware Corporation Law provides, in general,
that a corporation shall have the power to purchase and maintain insurance on
behalf of any person who is or was a director or officer of the corporation
against any liability asserted against the person in any such capacity, or
arising out of the person's status as such, whether or not the corporation would
have the power to indemnify the person against such liability under the
provisions of the Delaware Corporation Law. The Company has obtained a
directors' and officers' liability insurance policy, which insures the Company's
directors and officers against certain liabilities, including liabilities for
which the Company may not be able to indemnify such persons. The Company has
also entered into indemnification agreements with certain of its directors and
executive officers, which provide for indemnification against expenses,
judgments, fines and settlements in connection with threatened or pending
litigation, inquiries or investigations that arise out of the director's or
officer's acts or omissions in his capacity as a director or officer of the
Company to the extent permitted by Delaware law.

         Article Eight of the Registrant's Restated Certificate of Incorporation
and Article V of the Registrant's Amended and Restated Bylaws provide for
indemnification and/or exculpation to the fullest extent authorized by the
Delaware Corporation Law for any person who is or was a director or officer of
the Registrant who is or was involved or threatened to be made so involved in
any proceeding, whether civil, criminal, administrative or investigative, by
reason of the fact that such person is or was serving as a director or officer
of the Registrant or was serving at the request of the Registrant as a director
or officer of any other enterprise.

         The foregoing is only a general summary of certain aspects of Delaware
law and the Registrant's organizational documents dealing with indemnification
of directors and officers, and does not purport to be complete. It is qualified
in its entirety by reference to the detailed provisions of Section 145 of the
Delaware Corporation Law, Article Eight of the Registrant's Restated Certificate
of Incorporation and Article V of the Registrant's Amended and Restated Bylaws.

ITEM 7.       EXEMPTION FROM REGISTRATION CLAIMED.

         Not applicable.

ITEM 8.       EXHIBITS.

         Reference is made to the Exhibit Index filed herewith.

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:


<PAGE>


              (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 the 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 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 the registration statement or any
material change to such information in the 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 reports filed with or furnished to the
Commission by the Registrant pursuant to Section 13 or Section 15(d) of the
Securities Exchange Act of 1934 that are incorporated by reference in the
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.

         (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
Securities Exchange Act of 1934 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 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 Securities and
Exchange 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.

Registrant certifies that it has reasonable grounds to believe that it meets all
of the requirements for filing on Form S-8 and has duly caused this Registration
Statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in the County of St. Louis, State of Missouri, as of October 24,
2006.

         The opinion as to the legality of the securities registered hereunder

stock, holds options to purchase shares of such common stock, restricted stock
units and performance shares and participates in the Company's employee benefit
plans.

ITEM 6.       INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         Section 145(a) of the General Corporation Law of the State of Delaware
("Delaware Corporation Law") provides, in general, that a corporation shall have
the power to 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), because the person is or was a director
or officer of the corporation. Such indemnity may be against expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by the person in connection with such action, suit or
proceeding, if the person acted in good faith and in a manner the person
reasonably believed to be in or not opposed to the best interests of the
corporation and if, with respect to any criminal action or proceeding, the
person did not have reasonable cause to believe the person's conduct was
unlawful.

         Section 145(b) of the Delaware Corporation Law provides, in general,
that a corporation shall have the power to 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 because the person is or was a director or officer of the
corporation, against any expenses (including attorneys' fees) actually and
reasonably incurred by the person in connection with the defense
or settlement of such action or suit if the person acted in good faith and in a
manner the person reasonably believed to be in or not opposed to the best
interests of the corporation, except that no indemnification shall 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 of Chancery or the court in which such action or suit was brought shall
determine upon application that, despite the adjudication of liability but in
view of all the circumstances of the case, such person is fairly and reasonably
entitled to indemnity for such expenses which the Court of Chancery or such
other court shall deem proper.

         Section 145(g) of the Delaware Corporation Law provides, in general,
that a corporation shall have the power to purchase and maintain insurance on
behalf of any person who is or was a director or officer of the corporation
against any liability asserted against the person in any such capacity, or
arising out of the person's status as such, whether or not the corporation would
have the power to indemnify the person against such liability under the
provisions of the Delaware Corporation Law. The Company has obtained a
directors' and officers' liability insurance policy, which insures the Company's
directors and officers against certain liabilities, including liabilities for
which the Company may not be able to indemnify such persons. The Company has
also entered into indemnification agreements with certain of its directors and
executive officers, which provide for indemnification against expenses,
judgments, fines and settlements in connection with threatened or pending
litigation, inquiries or investigations that arise out of the director's or
officer's acts or omissions in his capacity as a director or officer of the
Company to the extent permitted by Delaware law.

         Article Eight of the Registrant's Restated Certificate of Incorporation
and Article V of the Registrant's Amended and Restated Bylaws provide for
indemnification and/or exculpation to the fullest extent authorized by the
Delaware Corporation Law for any person who is or was a director or officer of
the Registrant who is or was involved or threatened to be made so involved in
any proceeding, whether civil, criminal, administrative or investigative, by
reason of the fact that such person is or was serving as a director or officer
of the Registrant or was serving at the request of the Registrant as a director
or officer of any other enterprise.

         The foregoing is only a general summary of certain aspects of Delaware
law and the Registrant's organizational documents dealing with indemnification
of directors and officers, and does not purport to be complete. It is qualified
in its entirety by reference to the detailed provisions of Section 145 of the
Delaware Corporation Law, Article Eight of the Registrant's Restated Certificate
of Incorporation and Article V of the Registrant's Amended and Restated Bylaws.

ITEM 7.       EXEMPTION FROM REGISTRATION CLAIMED.

         Not applicable.

ITEM 8.       EXHIBITS.

         Reference is made to the Exhibit Index filed herewith.

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 the 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 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 the registration statement or any
material change to such information in the 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 reports filed with or furnished to the
Commission by the Registrant pursuant to Section 13 or Section 15(d) of the
Securities Exchange Act of 1934 that are incorporated by reference in the
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.

         (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
Securities Exchange Act of 1934 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 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 Securities and
Exchange 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.
SIGNATURES

         Pursuant to the requirements of the Securities Act of 1933, the
Registrant certifies that it has reasonable grounds to believe that it meets all
of the requirements for filing on Form S-8 and has duly caused this Registration
Statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in the County of St. Louis, State of Missouri, as of October 24,
