(1)  This Registration Statement also relates to such additional and
     indeterminable number of UMB Financial Corporation common shares, par value
     $1.00 per share ("Common Shares"), as may become issuable due to
     adjustments for changes resulting from stock dividends, stock splits,
     recapitalizations, mergers, reorganizations, combinations or exchanges or
     other similar events. 
(2)  This Registration Statement also relates to rights to purchase Common
     Shares of the Registrant which are attached to all Common Shares issued,
     pursuant to the terms of the Registrant's Rights Agreement dated as of
     August 4, 1995. Until the occurrence of certain prescribed events, the
     rights are not exercisable, are evidenced by the certificate for the Common
     Shares and will be transferred with and only with such Common Shares.
     Because no separate consideration is paid for the rights, the registration
     fee therefore is included in the fee for Common Shares. 
(3)  Estimated solely for the purpose of calculating the registration fee in
     accordance with Rule 457(c) and (h)(1) under the Securities Act of 1933,
     based on the average of the high and low price of the Common Shares
     reported on the Nasdaq National Market on May 13, 2005.

Item 5.  Interests of Named Experts and Counsel

         Not applicable

Item 6.  Indemnification of Directors and Officers

         In accordance with Section 355 of The General and Business Corporation
Law of Missouri, Article IX, Section 4 of UMB Financial Corporation's Bylaws
provide as follows with respect to the indemnification of directors and
officers:

         Section 4.  Indemnification of Directors and Officers.

         1.  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 he is or was a
director, officer or employee of the Corporation or any of its subsidiaries, or
is or was serving at the request of the Corporation as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust or
other enterprise (which shall be deemed to include any employee benefit plan of
the Corporation or any other corporation) shall be indemnified against expenses
(including attorneys' fees), judgments, fines and amounts paid in settlement
(which shall include any excise taxes assessed against a person with respect to
an employee benefit plan) actually and reasonably incurred by him in connection
with such action, suit or proceeding so long as: (a) such indemnification is
permissible under applicable provisions of law and regulations; and (b) the
results of an investigation of the matter as described in Section 5 includes a
finding under the provisions of Section 5 that he acted in good faith and in a
manner he reasonably believed to be in or not opposed to the best interests of
the Corporation or the participants or beneficiaries of any employee benefit
plan, and, with respect to any criminal action or proceeding, had no reasonable
cause to believe his conduct was unlawful.

         2.  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
he is or was a director, officer or employee of the Corporation, or is or was
serving at the request of the Corporation as a director, officer or employee of
another corporation, partnership, joint venture, trust or other enterprise
(which shall be deemed to include any employee benefit plan of the Corporation
or any other corporation) shall be indemnified against expenses (including
attorneys' fees) and amounts paid in settlement (which shall include any excise
taxes assessed against a person with respect to an employee benefit plan)
actually and reasonably incurred by him in connection with the defense or
settlement of the action or suit so long as (a) such indemnification is
permissible under applicable provisions of law and regulations; and (b) the
results of an investigation of the matter as described in Section 5 includes a
finding under the provisions of Section 5 that he acted in good faith and in a
manner he reasonably believed to be in or not opposed to the best interests of
the Corporation or the participants or beneficiaries of any employee benefit
plan; provided however that no such indemnification shall be made in respect of
any claim, issue or matter as to which such person shall have been adjudged to
be liable for negligence or misconduct in the performance of his or her duty to
the Corporation unless and only to the extent that the court in which the action
or suit was brought determines upon application that, despite the adjudication
of liability and in view of all the circumstances of the case, that the person
is fairly and reasonably entitled to indemnity for such expenses which the court
shall deem proper.

         3.  The termination of any action, suit, or proceeding by judgment, 
order, settlement, conviction, or upon a plea of nolo contendere or its
equivalent, shall not, of itself, create a presumption that the person did not
act in good faith and in a manner which he reasonably believed to be in or not
opposed to the best interest of the Corporation, and, with respect to any
criminal action or proceeding, had reasonable cause to believe that his conduct
was unlawful.

         4.  Any person who has been successful on the merits or otherwise in
defense of any action, suit or proceeding referred to in Sections 1 or 2 above,
shall be indemnified against expenses (including attorneys' fees) actually and
reasonably incurred by him in connection therewith.

         5.  Except as provided in Section 4, indemnification of anyone under
Sections 1 or 2, unless ordered by a court, shall be made by the Corporation
only as authorized in each case upon a determination that it is proper


                                      II-2






because the director, officer or employee has met the applicable standard of
conduct set forth. Such a determination shall be made by the Board of Directors
by a majority vote of a quorum consisting of directors who were not parties to
the action, suit or proceeding, or if such a quorum is not obtainable, or even
if obtainable, a quorum of disinterested directors so directs, by independent
legal counsel in a written opinion, or by the shareholders.

         6.  Notwithstanding anything herein to the contrary, no director, 
officer or employee shall be indemnified against any expenses, penalties or
other payments incurred in an administrative proceeding or action instituted by
a bank regulatory agency to the extent that such indemnification would
constitute a "prohibited indemnification payment" (as such term is defined under
applicable provisions of the Federal Deposit Insurance Act and regulations
thereunder, as amended from time to time) except under circumstances
specifically permitted by such Act and regulations, or that would otherwise
constitute an indemnification payment that is prohibited by applicable
provisions of law or regulations.

         7.  If authorized by the Board of Directors and if permissible under
applicable law and regulation, the Corporation may advance the costs and
expenses incurred in defending a civil or criminal action, suit or proceeding
upon receipt of an undertaking by or on behalf of the director, officer or
employee to repay such amount if it is ultimately determined that he is not
entitled to indemnification.

         8.  The Corporation may purchase and maintain insurance on behalf of 
any person who is or was a director, officer or employee of the Corporation or
is or was serving at the request of the Corporation as a director, officer or
employee of another corporation, partnership, joint venture, trust or other
enterprise against any liability for which it may indemnify such people under
the terms of this Article, and against other liabilities to the extent permitted
by applicable law and regulations.

         9.  The indemnification provided for directors, officers or employees
of the Corporation shall not be deemed exclusive of any other rights to which
those officers, directors or employees may be entitled under any by-law,
agreement, vote of shareholders or disinterested directors or otherwise, both as
to actions in his or her official capacity and as to actions in another capacity
while holding such office, and shall continue as to any person who has ceased to
be a director, officer or employee of the Corporation and shall inure to the
benefit of his or her heirs, executors and administrators.

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 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
                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 SEC 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;

           (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 (i) and (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.

      (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.

      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.

                                      II-4



      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 SEC, 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.


                                      II-5



                                   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 City of Kansas City, State of Missouri, on May 18, 2005.
