                              PLAN OF DISTRIBUTION

          The Selling Shareholders acquired the shares listed above as a result
of a merger between our wholly-owned subsidiary CBI Leasing, Inc., a Missouri
corporation, and The Vaughn Group, Inc., an Ohio corporation.

          The Company is registering the shares on behalf of the Selling
Shareholders. As used herein, "Selling Shareholders" includes donees, pledgees
and assignees selling shares received from a named Selling Shareholder after the
date of this prospectus. All costs, expenses and fees in connection with the
registration of the shares offered hereby will be borne by the Company.
Brokerage commissions and similar selling expenses, if any, attributable to the
sale of shares will be borne by the Selling Shareholders. Sales of shares may be
effected by Selling Shareholders from time to time in one or more types of
transactions (which may include block transactions) on the Nasdaq National
Market, in the over-the-counter market, in negotiated transactions or by any
other legal means, through put or call options transactions relating to the
shares, through short sales of shares, or a combination of such methods of sale,
at market prices prevailing at the time of sale, or at negotiated prices. Such
transactions may or may not involve brokers or dealers. The Selling Shareholders
have advised the Company that they have not entered into any agreements,
understandings or arrangements with any underwriters or broker-dealers regarding
the sale of their securities, nor is there an underwriter or coordinating broker
acting in connection with the proposed sale of shares by the Selling
Shareholders.

         The Selling Shareholders may effect such transactions by selling shares
directly to purchasers or to or through broker-dealers, which may act as agents
or principals. Such broker-dealers may receive compensation in the form of
discounts, concessions, or commissions from the Selling Shareholders and/or the
purchasers of shares for whom such broker-dealers may act as agents or to whom
they sell as principal, or both (which compensation as to a particular
broker-dealer might be in excess of customary commissions).

          The Selling Shareholders and any broker-dealers that act in connection
with the sale of shares might be deemed to be "underwriters" within the meaning
of Section 2(11) of the Securities Act, and any commissions received by such
broker-dealers and any profit on the resale of the shares sold by them while
acting as principals might be deemed to be underwriting discounts or commissions
under the Securities Act. The Company has agreed to indemnify each Selling
Shareholder against certain liabilities, including liabilities arising under the
Securities Act. The Selling Shareholders may agree to indemnify any agent,
dealer or broker-dealer that participates in transactions involving sales of the
shares against certain liabilities, including liabilities arising under the
Securities Act.

          Because Selling Shareholders may be deemed to be "underwriters" within
the meaning of Section 2(11) of the Securities Act, the Selling Shareholders
will be subject to the prospectus delivery requirements of the Securities Act.
The Company has informed the Selling Shareholders that the anti-manipulative
provisions of Regulation M promulgated under the Exchange Act may apply to their
sales in the market.

          Selling Shareholders also may resell all or a portion of the shares in
open market transactions in reliance upon Rule 144 under the Securities Act,
provided they meet the criteria and conform to the requirements of such Rule.

          Upon the Company being notified by a Selling Shareholder that any
material arrangement has been entered into with a broker-dealer for the sale of
shares through a block trade, special offering, exchange distribution or
secondary distribution or a purchase by a broker or dealer, a supplement to this
prospectus will be filed, if required, pursuant to Rule 424(b) under the Act,
disclosing (i) the name of each such Selling Shareholder and of the
participating broker-dealer(s), (ii) the number of shares involved, (iii) the
price at which such shares were sold, (iv) the commissions paid or discounts or
concessions allowed to such broker-dealer(s), where applicable, (v) that such
broker-dealer(s) did not conduct any investigation to verify the information set
out or incorporated by reference in this prospectus and (vi) other facts
material to the transaction. In addition, upon the Company being notified by a
Selling Shareholder that a donee or pledgee intends to sell more than 500
shares, a supplement to this prospectus will be filed.



                                  LEGAL OPINION

         Blackwell Sanders Peper Martin LLP, Two Pershing Square, 2300 Main
Street, Kansas City, Missouri 64108 is issuing a legal opinion attesting to the
validity of the shares of the Company's common stock registered hereby.

                                     EXPERTS

         The consolidated financial statements of Commerce Bancshares, Inc. as
of December, 31, 2001 and 2000, and for each of the years in the three-year
period ended December 31, 2001, have been incorporated by reference herein in

                                     PART II

Item 14.  Other Expenses of Issuance and Distribution.

         The following is an itemized statement of estimated expenses to be paid
by the registrant in connection with the issuance and sale of the common stock
being registered.

         Securities and Exchange Commission registration fee  (Actual)   $  537.69
         Accounting fees and expenses                                     5,000.00
         Legal fees and expenses                                          4,534.25
         Miscellaneous                                                      -0-
                                                                        ----------
                  Total                                                 $10,071.94

All other expenses in connection with the issuance and sale of the common stock
being registered will be borne by the Selling Shareholders.

Item 15.  Indemnification of Directors and Officers.

         Section 351.355 of the Missouri Revised Statutes (1986) allows
indemnification of corporate directors and officers by a corporation under
certain circumstances as therein specified against liabilities, expenses,
counsel fees and costs reasonably incurred in connection with or arising out of
any action, suit, proceeding or claim in which such person is made a party by
reason of such person being or having been such director or officer.

         Section 351.355 also permits such persons to seek indemnification under
any applicable bylaw, agreement, vote of shareholders or disinterested directors
or otherwise. Section 351.355 also permits corporations to maintain insurance
for officers and directors against liabilities incurred while acting in such
capacities whether or not the corporation would be empowered to indemnify such
persons under this section.

         The Company's bylaws contain a provision entitling officers and
directors to be indemnified by the Company from and against any and all of the
expenses, liabilities or other matters covered by said provision. To satisfy
the obligations under this bylaw provision, the Company has obtained insurance
policies for officers and directors liability.  The coverages and policy limits
are approved annually by the Board of Directors.

Item 17.  Undertakings

         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 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 Act and will be governed by the final adjudication of
such issue.

         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 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to 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.

         The undersigned registrant hereby undertakes:

                  (1) To file, during any period in which offers or sales are
         being made of 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 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; and

                           (iii) To include any material information with
