                            UMB FINANCIAL CORPORATION

      UMB Financial Corporation, a Missouri corporation ("UMB"), is a registered
bank  holding  company and a financial  holding  company  under the Bank Holding
Company  Act.  UMB is  supervised  and  examined by the Federal  Reserve  Board.
Through  its  subsidiaries,  UMB  provides a variety of  lending  and  financial
services to  individuals,  businesses and  government  entities in the States of

Dakota and Arizona.  UMB's principal executive offices are located at 1010 Grand
Boulevard, Kansas City, Missouri 64106. Its telephone number is (816) 860-7000.

                             DESCRIPTION OF THE PLAN

      The following questions and answers constitute the Plan in its entirety.

Purpose

      1.  What is the Plan's purpose?

      The primary  purpose of the Plan is to provide  eligible UMB  shareholders
with a convenient and  cost-effective way to increase their investment in UMB by
investing  cash  dividends and optional cash payments in additional  UMB shares.
The Plan also provides an economical and convenient  method for UMB employees to
become shareholders and to increase their investment in UMB.

      The Plan  Administrator  may buy  shares of UMB  common  stock on the open
market or directly from UMB. If the Plan  Administrator  buys from UMB, the Plan
has the added  benefit  of  providing  UMB with  additional  funds  for  general
corporate purposes.

      The Plan is intended  for the benefit of long-term  investors  and not for
the benefit of  individuals  or  institutions  who engage in short-term  trading
activities  which cause temporary  fluctuations in the composite  trading volume
and market price of shares.

Advantages

      2.  What are the advantages of the Plan?

          o    You may  acquire  additional  UMB shares by having all or part of
               your UMB  common  stock  dividends  automatically  reinvested  in
               additional  shares of UMB common stock,  without  commissions  or
               service fees.

          o    You may  increase  your  holdings  in UMB common  stock by making
               purchases in a variety of ways - by check,  payroll deduction (if
               you are  employed  by UMB or one of its  affiliates)  or  monthly
               automatic  deductions  directly  from  your  U.S.  bank  account,
               without commissions or service fees.

          o    You may purchase UMB common stock in whole dollar amounts, rather
               than a specific quantity of shares,  with the appropriate  number
               of full and fractional shares credited to your account.

                                       2



          o    You may deposit common stock  certificates  into your account and
               have your  ownership of common  stock  maintained  in  book-entry
               form.

          o    You will receive regular statements  indicating  activity in your
               account.

Participation

      3.   Who is eligible to participate in the Plan?

           Record  Owners.  If you own UMB  stock in your own name as a  "record
owner," you are eligible to participate in the Plan.

           Beneficial Owners. You are a "beneficial owner" if your stock is held
in a brokerage account or in the name of a broker, bank or other nominee. If you
are a beneficial owner, you may participate in the Plan in one of two ways:

           o   You may participate directly in the dividend reinvestment feature
               of the Plan by becoming a record  owner.  You may arrange this by
               having one or more shares of UMB stock transferred into your name
               from that of your broker, bank or other nominee, or

           o   You may ask the broker,  bank or other  nominee who is the record
               owner to  participate  on your  behalf.  Except for  instructions
               received from brokers and bank nominees,  the Plan  Administrator
               cannot recognize  instructions  received from anyone acting as an
               agent on your behalf in the Plan.

           Employees.  If you are an employee  of UMB or one of its  affiliates,
you are eligible to participate in the Plan.



                                       3



      4.  Are there  limitations on  participation  in the Plan other than those
          described above?

      We  may,  for  any  reason  or no  reason,  decide  not  to  allow  you to
participate in the Plan even if you qualify for  participation in this Plan. For
example,  some  stockholders or employees may be residents of  jurisdictions  in
which UMB  determines  that it may not be legally or  economically  practical to
offer  UMB  stock  under  this  Plan.  UMB  may  preclude   residents  of  those
jurisdictions from participating in this Plan. UMB reserves the right to modify,
suspend  or  terminate  your  participation  in the Plan in  order to  eliminate
practices that UMB believes are inconsistent with the purposes of the Plan.

      You may not  transfer  your right to  participate  in this Plan  except by
transferring your interest in UMB stock to another person.

      5.  How do I participate in the Plan?

      If you  are a  record  owner  of UMB  stock,  you  may  join  the  Plan by
completing  and  signing  an  Authorization  Form and  returning  it to the Plan
Administrator.

      If you are a beneficial  owner and wish to join the Plan, you must contact
your bank, broker or other nominee to arrange  participation in the Plan on your
behalf.  To  facilitate   participation  by  beneficial  owners,  UMB  has  made
arrangements  with the Plan  Administrator  to  reinvest  dividends  and  accept
optional cash payments under the stock  purchase  feature of this Plan by record
owners  such as  brokers,  banks and  other  nominees,  on behalf of  beneficial
owners.  Alternatively,  you may simply request that the number of shares of UMB
stock you wish to be enrolled in this Plan be reregistered  by the bank,  broker
or other nominee in your name as record owner.  You can then  participate in the
Plan directly.

      If you are an employee of UMB or one of its  affiliates,  you may join the
Plan by completing and signing an Authorization  Form and returning it, together
with a minimum  initial  investment of $25, to the Plan  Administrator.  You can
make your investments by personal check or money order payable to UMB Bank, N.A.
Do Not Send  Cash.  Once you are  enrolled  in the Plan,  you may also make your
investments by automatic payroll deduction (if you are an employee of UMB or one
of its affiliates) or monthly automatic  deductions from your U.S. bank account,
as described on the Authorization Form. You may also make monthly investments by
check.

      Your participation in the Plan begins when the Plan Administrator  accepts
your properly completed and signed  Authorization  Form. In order to participate
in a particular  dividend,  your  enrollment  must be effective on or before the
record date established for such dividend. If the Authorization Form is accepted
after  that  record  date,  your  enrollment  will be  effective  for  the  next
investment period, although you will still be a Plan participant.

      6.  When may I enroll in the Plan?

      If you are eligible to participate in the Plan (as described in Question 3
above),  you may  enroll  in the Plan at any time.  Once  enrolled,  you  remain
enrolled until your participation is terminated at your request or by UMB.

Investment Options

      7.  What investment options are available under the Plan?

      Your  investment  options  under the Plan are listed on the  Authorization
Form.  You can indicate  which features of the Plan you will use by checking the
appropriate box on the Authorization Form.

          (a)  Full Reinvestment of Dividends: Select this option if you wish to
     reinvest all dividends on all UMB stock  registered  in your name.  You may
     also make optional cash payments.

          (b)  Partial Reinvestment of Dividends: Select this option if you wish
     to reinvest the  dividends on a specific  percentage of shares of UMB stock
     registered in your name.  Dividends on remaining shares will be paid to you
     in cash or by direct deposit. You may also make optional cash payments.

          (c)  Optional  Cash Payments  Only:  Select this option if you wish to
     participate in the Plan by making optional cash payments.  You will receive
     cash dividends (if and to the extent  declared by UMB's board of directors)
     on all UMB stock registered in your name.

     IMPORTANT:

     o  If  you  return  a  properly  signed  Authorization  Form  to  the  Plan
        Administrator without any boxes checked, the Plan Administrator will not
        process  the form and will  return  it to you to  select  an  investment
        option.

     o  The Plan  Administrator  will not process your Authorization Form if the
        form does not have the proper signature(s).

     8.   Are there any fees or expenses to enroll in the Plan or in  connection
          with purchases under the Plan?

      You will not pay any fees or expenses to enroll in the Plan.  UMB pays all
fees of UMB  Bank,  N.A.  for  administering  the  Plan.  You  will  not pay any
brokerage commissions, service charges or fees on shares that you purchase under
the Plan.

      9.  How do I make optional cash payments?

      Optional  cash  payments  allow you to purchase more shares than you could
otherwise  purchase by only reinvesting your cash dividends.  You may buy shares
of our common  stock with  optional  cash  payments  after you submit a properly
signed  Authorization  Form. The Plan  Administrator will use your optional cash
payment to purchase  common stock for your Plan account  after it receives  your
cash payment. You have no obligation to make optional investments.

      You may  invest  optional  cash  payments  even if you have not  chosen to
reinvest your cash dividends. If you choose to make only optional cash payments,
UMB will pay you cash

                                       5



dividends  when and as  declared on any shares of UMB stock  registered  in your
name, as well as on full and fractional shares held in your Plan account.

      You may make your first optional cash payment when you enroll by enclosing
a check or money  order,  in the  amount  of at least  $25,  and  returning  it,
together with the Authorization Form, to the Plan  Administrator.  Checks should
be made payable to UMB Bank,  N.A.  Once you are  enrolled in the Plan,  you may
make  optional  cash  payments by  completing  the tear-off  remittance  portion
attached to your account  statement.  Optional  cash payments need not be in the
same amount each time.

      If you elect to make optional  cash payments by check or money order,  you
must  mail  funds to the  address  indicated  on the  Authorization  Form or the
remittance form, as the case may be. If the Plan  Administrator does not receive
your funds and remittance  form at least two (2) business days prior to the next
investment date, then your optional cash payments will not be invested until the
next investment date.

      If any check you deliver to the Plan Administrator is returned unpaid, the
Plan  Administrator  may consider the request for the  investment  of such money
null and void and may  immediately  remove  from your  account  shares of common
stock purchased with that payment.  The Plan  Administrator will charge a fee of
$25 for any returned checks.

      You can automatically invest a specified monthly amount (not less than $25
and not more than $3,000  quarterly)  from your U.S.  bank account by completing
the automatic  deduction section on the  Authorization  Form and returning it to
the Plan Administrator.  Funds will be transferred from your bank account on the
26th day of each  month.  If the 26th is not a business  day,  the funds will be
deducted on the next business day. The Plan Administrator will invest such funds
in UMB shares on the first (1st)  business day of each month.  You can change or
stop   automatic   monthly   investments  by  completing  and  returning  a  new
Authorization  Form  and  returning  it to  the  Plan  Administrator.  The  Plan
Administrator  must  receive  your  instructions  and  authorization  three  (3)
business days prior to the 26th day of each month.

      If you are an employee of UMB or one of its  affiliates,  you can invest a
specified  monthly  amount (of at least  $12.50 per pay period and not more than
$3,000 quarterly) by payroll  deduction by completing an Authorization  Form and
sending it to the Plan  Administrator.  The Plan  Administrator must receive the
Authorization Form by the 24th day of the month to be effective by the first pay
period of the next month.

      10.  What are the limitations on optional cash payments?

      You may make optional cash  payments by check at any time.  However,  your
optional cash payments may not exceed $3,000 in any calendar  quarter unless UMB
approves  your Request for Waiver,  as described in Question 11 below.  UMB will
not accept  optional cash  payments of less than $25.  Optional cash payments of
less than $25 and that  portion of any  optional  cash  payment that exceeds the
maximum quarterly purchase limit will be returned to you, without interest.  You
do not  have to send the  same  amount  of money  each  month,  and  there is no
requirement that you make an optional cash payment each month.


                                       6




      11. Is it  possible  for me to invest  more than $3,000 per quarter in UMB
          common stock?

      Yes.  If you  submit a  Request  for  Waiver  Form and UMB  approves  your
request, you may invest more than the $3,000 maximum in any calendar quarter for
UMB common  stock.  No  pre-established  maximum  limit applies to optional cash
payments  that may be made  pursuant to a Request for Waiver.  You should submit
your Request for Waiver Form directly to UMB by registered mail,  return receipt
requested,  or some other form of  traceable  mail,  and UMB must  receive it at
least five (5)  business  days  prior to an  upcoming  investment  date for such
Request  for  Waiver  to be  reviewed  in time for a  purchase  to occur on such
investment  date. UMB will promptly notify you whether UMB approved your request
and, if approved,  the amount of your request  that UMB  approved.  To receive a
Request  for  Waiver   Form,   you  may  contact  the  Plan   Administrator   at
1-800-884-4225 or by electronic mail at stock.transfer@umb.com.

      UMB may grant or deny any  Request for Waiver for any reason or no reason.
If you and other participants request to invest amounts that are, in total, more
than what UMB would accept, UMB may honor your request and the requests of other
participants,  in whole or in part,  on a pro rata basis or by any other  method
UMB deems appropriate.

      12. May the Plan Administrator  return optional cash payments if I request
          a return of such payments?

      The Plan  Administrator  will not return any optional cash payments unless
you notify the Plan  Administrator  in  writing at least two (2)  business  days
prior  to the  relevant  investment  date.  The  Plan  Administrator  may  delay
returning any optional cash payments to you for a reasonable period.

Purchases Under the Plan

      13. What is the "investment date"?

      On the investment date, or promptly  thereafter (as determined by the Plan
Administrator in its sole discretion),  shares of UMB common stock are purchased
by the Plan Administrator with reinvested dividends and optional cash payments.

        o Reinvested Dividends:For the reinvestment of dividends, the investment
date  is the  date  declared  by the  board  of  directors  for the  payment  of
dividends.  If UMB stock is not traded on the dividend  payment  date,  then the
investment date shall be the next trading day. The record date associated with a
particular dividend is referred to in this Plan as a "dividend record date."

        o Optional Cash Payments: The investment date will be the first business
day of every calendar month except the months in which dividends are to be paid,
in which case the investment  date will be the same as the  investment  date for
the  reinvestment of dividends.  On the investment date or promptly  thereafter,
the Plan  Administrator  will purchase  shares of UMB common stock in accordance
with the  instructions  on your  Authorization  Form and the  terms of the Plan.
Optional cash payments received after the second (2nd) business day preceding an
investment date will not be invested until the following investment date.

                                       7


      14.  At what price will shares be purchased under the Plan?

      If the Plan  Administrator  purchases  common stock directly from UMB, the
price per share will be the  average of the daily high and low prices of the UMB
common  stock as reported on the NASDAQ for the five (5) trading days before the
applicable investment date.

      If the Plan  Administrator  purchases common stock from parties other than
UMB, either in the open market or in privately  negotiated  purchases,  then the
price per share will be the weighted  average of the actual prices that the Plan
Administrator  pays for all of the shares of common stock  purchased by the Plan
Administrator for such investment period.

      15.  How will I be notified of my purchases of common stock?

      The Plan  Administrator will send you a statement showing the activity and
balance in your Plan account as soon as  practicable  after each purchase of UMB
common stock on your  behalf.  Your  account  statement  will show the number of
shares purchased and their purchase price. Your account statement will also show
the total number of shares held in your account as of the investment date.

      You should keep your final  statement for each year for tax purposes.  The
Plan Administrator may charge you a fee if you request additional copies of your
prior account  statements.  You may also request a duplicate statement online at
http://shareholderview.umb.com.

      16. What is the source of the common stock that I purchase under the Plan?

      The Plan  Administrator  may elect to purchase  shares of common stock (i)
from  UMB in the  form of  newly  issued  shares  or  shares  held by UMB in its
treasury,  (ii) in the open market, (iii) in privately negotiated  transactions,
or (iv) through a combination  of the above  methods.  Participants  in the Plan
have no control over whether the Plan  Administrator  purchases  share of common
stock from UMB, in the open market, or in privately negotiated transactions.

      17.  How many shares of common stock will I purchase through the Plan?

      The number of shares of common stock that you purchase  depends on several
factors, including:

           o   the amount of  dividends  that you  request  to have  reinvested,
               including dividends on stock credited to your Plan account;

           o   the amount of any optional cash payments you make;

           o   whether the shares are purchased  directly from UMB or from third
               parties,  either  in the  open  market  or  privately  negotiated
               transactions; and

           o   the market price of the common stock on the applicable investment
               date.

      The Plan  Administrator will credit your account with the number of shares
equal to the total  amount to be  invested  divided by the  applicable  purchase
price.  The only limit on the

                                       8


number of shares  available for purchase is the number of shares of common stock
registered for issuance under the Plan.

Certificates for Shares of UMB Common Stock

      18.  Will  certificates  be issued  for shares of common  stock  purchased
           under the Plan?

      Normally the Plan  Administrator  will not issue  certificates  for shares
that you purchase  under the Plan until your account is terminated or you submit
a request for certificates, as described below. Your account statement will show
the number of shares held in your Plan account.  In addition to  minimizing  the
costs of the Plan,  this additional  service  protects  against loss,  theft, or
destruction of stock certificates.

      However,  you may at any time  request the Plan  Administrator  to issue a
certificate  for any whole number of shares of common stock, up to the number of
full shares credited to your Plan account. The Plan Administrator will generally
issue certificates  approximately three (3) business days after it receives your
request.  If the Plan  Administrator  receives  your  request to terminate on or
after an ex-dividend date and before the related  investment date, it will issue
your  certificate  after the related  investment  date.  Your request must be in
writing, and you should mail it to:

      If  you  are  not  terminating  your  participation  in the  Plan,  future
dividends  on any  shares  for which you  request  a stock  certificate  will be
treated according to your instructions indicated on the Authorization Form.

      We will not issue  certificates  for  fractional  shares of common  stock
under any circumstances.

      19.  In whose name will stock certificates be registered when issued?

      We will issue stock certificates  registered in your name as it appears on
your Plan account.

      You may ask the Plan  Administrator  to issue  certificates in names other
than the Plan account name, but you must comply with any applicable laws and you
must pay any applicable  taxes. You must make this request in writing,  and your
signature  must be guaranteed by a qualified  medallion  guarantee  member.  The
party receiving your shares must complete an  Authorization  Form and send it to
the Plan Administrator in order to participate in the Plan.

                                       9



      20.  Is a safekeeping service available to hold my shares?

      Yes. The Plan Administrator  will hold your shares in safekeeping  without
cost, thus eliminating the worry about certificates  being lost or stolen.  Your
account  statement  will  identify the number of shares of common stock you hold
and the number of shares in your Plan account.

      You may also transfer other shares of UMB common stock that are registered
in your name to your  Plan  account  at no cost.  This  eliminates  the need for
safekeeping  of the  certificates  for those  shares.  If you send  certificates
representing shares of common stock to the Plan Administrator,  please send them
by registered mail, return receipt requested,  and properly insured, because you
bear the risk if the  certificates  are lost or stolen in transit.  You may mail
certificates,  together  with a  written  request  to  have  the  certificate(s)
deposited in your Plan account, to the following address:

                          UMB Bank, N.A.
                          Securities Transfer Division
                          P.O. Box 410064
                          Kansas City, MO 64141-0064

Withdrawal and Sale of Shares in Plan Accounts

      21.  How may shares be withdrawn from the Plan?

      Any or all shares  credited to your account  from time to time,  including
shares deposited with the Plan  Administrator for safekeeping,  may be withdrawn
by notifying  UMB Bank,  N.A. in writing  specifying  the number of shares to be
withdrawn. Certificates for whole shares will be issued to and registered in the
name in which the Plan account is registered.

      22.  How may I sell stock held in my Plan account?

      You may sell some or all of your stock held in your Plan account,  whether
or not you are withdrawing  from this Plan. You may sell your shares through the
Plan  Administrator by sending the Plan  Administrator a request to sell some or
all of the shares held in your Plan account.  You will not be able to direct the
date or  price at  which  the Plan  Administrator  sells  your  stock.  The Plan
Administrator  will  attempt in good  faith to make the sale in the open  market
within five (5) trading days after  receiving  your request.  After the sale you
will receive the proceeds of the sale minus:

           o  a brokerage commission (currently 10 cents per share);

           o  any applicable taxes; and

           o  a sale processing fee (currently $10.00).

You may inquire about brokerage commissions or other fees by contacting the Plan
Administrator.

      The Plan  Administrator  will engage a broker to sell your shares, and the
broker may be affiliated  with the Plan  Administrator.  The Plan  Administrator
will mail you a check for the

                                       10



shares  you sell  after it  receives  the funds  from the  brokerage  firm.  UMB
provides all  information  regarding the sale of shares to the Internal  Revenue
Service.

      If you wish to sell some or all of the  shares in your Plan  account,  you
should send a request to the Plan Administrator at:

                          UMB Bank, N.A.
                          Securities Transfer Division
                          P.O. Box 410064
                          Kansas City, MO 64141-0064

      Please  remember  that if you elect to sell your  stock  through  the Plan
Administrator,  the price of our  common  stock may  decline  during  the period
between the Plan Administrator's receipt of your request to sell your shares and
the date of the sale in the open market.  The Plan Administrator will attempt in
good faith to sell your shares within five (5) trading days after receiving your
request; provided, however, that if the Plan Administrator receives your request
to sell on or after an ex-dividend date and before the related  investment date,
it will sell your shares after the related investment date. You should carefully
evaluate  this risk,  which you bear.  You bear a similar  risk between the time
that  you  request  a  certificate  and the  time the  certificate  is  actually
delivered to you.

      23.  What  happens  when I sell or  transfer  all of the  shares of common
           stock held outside the Plan?

      If you sell or transfer  all shares of UMB stock  registered  in your name
outside  your  Plan  account,  the Plan  Administrator,  until  you  give  other
instructions,  will  continue to reinvest  the  dividends on the common stock in
your Plan account according to your instructions on the Authorization  Form. You
may also continue to  participate  in the optional cash payment  feature of this
Plan as long as there is at least one whole share of common  stock  remaining in
your Plan account.

      Please note that if your Plan account holds less than one full share,  UMB
may close your  account,  liquidate  the  fractional  share and send you a check
representing the market value of the fractional share that was in the account.

      24.  What happens to a fraction of a share of common stock when I withdraw
           from the Plan or the Plan is terminated?

      When you withdraw from the Plan or the Plan is terminated by UMB, the Plan
Administrator  will mail you a cash payment for any  fractional  share of common
stock. The cash payment will be based upon the market price at the time the Plan
Administrator processes your termination.

                                       11



Owning Stock in the Plan

      25.  How will I be credited with dividends on stock held in my Plan
           account?

      If and when declared by UMB's board of  directors,  UMB will pay dividends
to all holders of record of UMB stock. The Plan  Administrator  will receive and
credit  you  with  dividends  for all  stock  you  hold in the  Plan,  including
fractional  shares. The Plan Administrator will reinvest dividends in additional
shares  of  UMB  common  stock  or  distribute  dividends,   according  to  your
instructions.

      26.  Will I receive UMB's periodic reports and proxy statements?

      Yes.  UMB  will  send  you the  same  information  that it  sends to other
stockholders, including annual reports, notices of stockholders' meetings, proxy
statements,  and income tax information  for reporting  dividends paid. UMB will
also send you copies of each  prospectus  and any  amendments or  supplements to
prospectuses describing the Plan.

      27.  May I have dividends on stock held in the Plan sent directly to me?

      If you elect  the  partial  dividend  reinvestment  alternative,  you will
reinvest  dividends on the specified  percentage of shares of stock held in your
account.  All other  dividends  will be paid in cash.  Participants  making only
optional cash payments will have all cash  dividends  paid to them directly with
no reinvestment.

      You may  withdraw  shares from the Plan by written  notice.  When the Plan
Administrator  issues a stock  certificate  to you,  future  dividends  on these
shares of common  stock will be treated  according to the  instructions  on your
Authorization Form.

      28. What happens if UMB issues a stock dividend or declares a stock split?

      Any shares representing stock dividends (payable in common stock) or stock
splits that UMB  distributes on shares of UMB common stock credited to your Plan
account will be added to your Plan account.  Shares representing stock dividends
payable  other than in UMB common stock will be paid to the Plan  Administrator,
which  will   distribute  the  shares  in  accordance   with  the  interests  of
participants in the Plan.  Shares  representing  stock dividends or split shares
distributed on  certificates  registered in your name will be mailed directly to
you in the same manner as to stockholders who are not participating in the Plan.

      29.  If UMB issues rights to purchase  securities to the holders of common
           stock, how will the rights on Plan shares be handled?

      If UMB issues  transferable  rights to purchase  additional  shares of UMB
common stock or any other  securities to holders of our common  stock,  the Plan
Administrator  will  sell  those  rights  (if such  rights  are  detachable  and
saleable)  relating to shares of common stock held by the Plan Administrator for
participants and invest the proceeds in additional shares of common stock on the
next  investment  date.  In the event that those  rights are not  detachable  or
saleable, the Plan Administrator will hold those rights for your benefit. If you
wish to  receive  any  rights  directly,  you may do so by  sending  to the Plan
Administrator, at least five (5) trading days before the


                                       12



record date for the rights  offering,  a written request that  certificates  for
shares in your Plan account be sent to you.

      30.  How will the  stock  held  under  this Plan be voted at  meetings  of
           stockholders?

      You can vote all whole or  fractional  shares of common stock held in your
Plan  account in person or by the proxy card sent to you.  If you do not vote in
person or by proxy, your shares will go unvoted.

      31.  May I pledge shares in my Plan account?

      No.  You may not pledge any shares of UMB stock that you hold in your Plan
account. Any pledge of shares in a Plan account is null and void. If you wish to
pledge  shares,  you must first withdraw those shares from your Plan account and
request the Plan  Administrator  to issue  certificates for those shares in your
name.

Changes in Plan Participation

      32.  How can I change my participation in the Plan?

      If you elect to change your  participation  from the choices  made on your
initial  Authorization Form, you must complete a new Authorization Form and send
it to the Plan Administrator.

      33.  What are the costs and expenses if I change my participation in the
           Plan?

      UMB  will  pay all the  costs  in  connection  with  any  changes  in your
enrollment and participation, other than the brokerage commissions in connection
with the sale of shares and sale processing fees.

Other Information

      34.  Who bears the risk of price changes in the common stock?

      You  bear  the  financial   risk  of  changes  in  the  market  value  and
marketability  of all  shares,  whether  whole or  fractional,  of common  stock
enrolled in the Plan and allocated to your account.  You should  recognize  that
neither UMB nor the Plan  Administrator can provide any assurance of a profit or
protection against loss on shares purchased under the Plan.

      35.  May I set up an individual retirement account?

      You may establish a qualified individual  retirement account ("IRA") under
the Plan if permitted by the Plan Administrator and the custodian of your IRA.

      36.  What are some of my responsibilities under the Plan?

      You should notify the Plan Administrator promptly in writing of any change
of address. Account statements and other communications to you will be addressed
to the last address of record provided by you to the Plan Administrator.  If the
Plan Administrator cannot find you,


                                       13



your  shares  may be deemed  to have been  abandoned  under  state  laws and may
escheat to the state.

Termination of Participation in the Plan

      37.  How and when may I terminate participation in the Plan?

      You may close your Plan account at any time by providing written notice to
the Plan Administrator. The Plan Administrator will process your request as soon
as practicable,  in its sole discretion,  after any applicable pending dividend,
reinvestment or optional cash payment has been credited to your account.

      38.  May UMB terminate my participation in the Plan?

      Yes. UMB may terminate your account immediately,  for any reason or for no
reason, upon sending written notice to you at the last known address as shown on
the Plan  Administrator's  records.  Such termination will be effective when the
notice is sent. For example,  UMB may terminate your  participation upon receipt
of satisfactory  (determined by the Plan  Administrator  in its sole discretion)
written evidence of your death or adjudication of  incompetency,  in which case,
however,  dividend  payments received together with any shares held in your Plan
will be retained until satisfactory (determined by the Plan Administrator in its
sole discretion)  evidence of the appointment of your legal  representative  and
its right to receive the dividends, shares, or both, shall have been received by
the Plan Administrator. No interest shall be paid on any funds held pending such
appointment and delivery.

      39.  What will be done with the shares of common stock credited to my Plan
           account upon termination?

      Upon termination of your participation in the Plan, the Plan Administrator
typically  will send you a stock  certificate  for the number of whole shares in
your Plan account and a check in an amount equal to the value of any  fractional
shares based upon the prevailing market price, less applicable costs and fees in
connection with the sale not paid by UMB, as soon as practicable.

      Upon termination of your  participation in the Plan, if you do not wish to
receive a stock certificate for the number of whole shares in your account,  you
may request that such shares be sold by notifying  the Plan  Administrator.  The
Plan  Administrator  will  promptly  sell your  shares on the open  market.  The
proceeds of such sale (less any brokerage commissions and a sale processing fee)
will be promptly forwarded to you.

Modification, Suspension or Termination of the Plan by UMB

      40.  May UMB change or discontinue the Plan?

      While UMB  currently  intends to continue the Plan  indefinitely,  UMB may
amend,  suspend,  modify or  terminate  the Plan at any time.  UMB will  provide
notice of any  amendment,  suspension,  modification  or  termination.  The Plan
Administrator  may resign at any time upon reasonable  notice to UMB in writing.
UMB may elect and appoint at any time a new Plan Administrator to administer the
Plan.


                                       14




      41. Who  is  responsible   for  costs  and  expenses  if  UMB  changes  or
          discontinues the Plan?

      UMB will pay all the costs in connection with any modification, suspension
or termination of the Plan.

Administration of the Plan

      42. What are the responsibilities of UMB and the Plan Administrator?

      UMB and the Plan Administrator will not be liable for any act done in good
faith or for any good faith omission to act, including,  without limitation, any
claim of  liability  arising out of the failure to  terminate  your account upon
your death,  the prices at which shares are  purchased or sold for your account,
the times when  purchases  or sales are made or for  fluctuations  in the market
value of common stock.

      43. Who interprets and regulates the Plan?

      Any questions of interpretation arising under this Plan will be determined
by UMB and any determination  will be final. UMB may adopt rules and regulations
to facilitate  the  administration  of the Plan. The terms and conditions of the
Plan and its operation will be governed by the laws of the State of Missouri.

Important Tax Consequences

      44.  What are the federal income tax  consequences of participation in the
           Plan?

      In general,  if you enroll in the Plan, as of the date of this prospectus,
you will have the same federal income tax obligations with respect to reinvested
dividends as you would with dividends not reinvested under this Plan.

      You will be treated for federal income tax purposes as having received, on
each investment date, a cash  distribution  equal to the full amount of the cash
dividend payable on that date on the shares of common stock held in your account
and all other UMB stock that you own. The Internal  Revenue Code  requires  this
treatment  even though you never actually  receive the  reinvested  dividends in
cash because your dividends are used instead to purchase shares of common stock.
In the case of reinvested  dividends  used to purchase  stock  directly from us,
your tax basis in common stock acquired through dividend reinvestment will equal
the amount treated as a distribution for federal income tax purposes.

      If you make  optional  cash  payments,  and the optional cash payments are
used to purchase common stock directly from UMB in the form of treasury or newly
issued shares,  you will not recognize income for federal income tax purposes by
virtue of the purchase of common stock with the optional cash payments.  The tax
cost and basis of stock purchased with optional cash payments will be the amount
you paid for such stock.

      The federal  income tax  treatment  of purchases of common stock under the
Plan  from  third  parties  differs  from  purchases  directly  from  UMB in the
following manner. If you reinvest


                                       15



some or all of your dividends and the Plan purchases shares of common stock from
a third  party,  the per share cost of each share of stock will be  increased by
the per share,  pro rata portion of any  brokerage  fees and  transaction  costs
incurred in connection with such purchase. This amount will be added to your tax
basis in the  common  stock  you  acquire.  Your tax basis in the  common  stock
acquired  should  equal the amount you paid for the stock,  including  brokerage
fees and transaction costs, if any.

      The holding  period for stock  purchased  with  dividends or optional cash
payments begins on the day after the applicable investment date.

      Distributions  with  respect to your stock  will  generally  be taxable as
ordinary  dividend income for federal income tax purposes to the extent made out
of our current or accumulated  earnings and profits.  Distributions in excess of
our current or  accumulated  earnings  and  profits  will be treated for federal
income tax  purposes as a return of  capital.  The amount of a return of capital
would first reduce the tax basis of the common  stock to which the  distribution
is attributable to the extent of that tax basis, and the excess,  if any, of the
amount  treated as a return of capital over such tax basis would be treated as a
gain from the disposition of such stock. In the event that UMB designates a part
or all of the  amount  distributed  as a capital  gain  dividend,  the amount so
designated should be treated by you as long-term capital gain.

      You will  recognize  gain or loss  when a  fractional  share  interest  is
liquidated  or when you sell or  exchange  common  stock.  The gain or loss will
equal the  difference  between the amount you receive for the  fractional  share
interest  or the  common  stock and the tax basis  for the  fractional  share or
common stock.

      Tax  consequences  will vary  depending on your  specific  circumstances.
You should discuss specific tax questions  regarding your  participation in the
Plan with your own tax advisor.

      We urge you to save your account  statements  in order to calculate  your
tax basis per share of common stock.  The Plan  Administrator  may charge you a
fee for copies of past account statements.

      45.  What  provision  is made  for  stockholders  subject  to  income  tax
           withholding?

      If you are a foreign  stockholder  whose  dividends  are subject to United
States income tax  withholding,  or a domestic  stockholder  whose dividends are
subject to backup  withholding  taxes, the Plan  Administrator  will reinvest an
amount equal to the dividend less the amount of any tax required to be withheld.
Optional cash payments may also create a withholding  obligation with respect to
any deemed  distribution  that  results.  UMB will have  amounts  withheld  from
dividends,  and any other  amounts  required to be withheld,  paid to the United
States Treasury and the respective  participants  will be advised of the amounts
withheld.

FOREIGN STOCKHOLDERS WHO ELECT TO MAKE OPTIONAL CASH PAYMENTS ONLY WILL CONTINUE
TO RECEIVE CASH DIVIDENDS ON STOCK  REGISTERED IN THEIR NAMES IN THE SAME MANNER
AS IF THEY WERE NOT PARTICIPATING IN THIS PLAN. FUNDS FOR OPTIONAL CASH PAYMENTS
MUST BE IN UNITED STATES DOLLARS AND WILL BE INVESTED IN THE SAME

                                       16


WAY AS PAYMENTS FROM OTHER PARTICIPANTS. CHECKS MUST BE DRAWN ON A UNITED STATES
BANK.

                                 USE OF PROCEEDS

      UMB will receive  proceeds from the sale of its shares held in treasury or
newly issued shares of common stock purchased by the Plan Administrator directly
from UMB.  UMB intends to use the  proceeds  from the sale of such shares of UMB
common stock for general corporate purposes.

      UMB has no basis  for  estimating  either  the  number of shares of common
stock  that  ultimately  will be sold  under the Plan or the prices at which the
shares will be sold.  UMB will not receive any proceeds  under the Plan from the
purchase of shares of common stock by the Plan  Administrator from parties other
than us.

          AVAILABLE INFORMATION/INCORPORATION OF DOCUMENTS BY REFERENCE

      UMB files annual,  quarterly and current  reports,  proxy  statements  and

                     FACTORS THAT MAY AFFECT FUTURE RESULTS

      Please  keep in mind  that the  information  delivered  to you  with  this
prospectus,  as well as the  annual,  quarterly  and  other  reports,  and other
information filed by UMB with the SEC contain  forward-looking  statements which
involve  various  uncertainties.  These  uncertainties  could  cause  actual UMB
results to be materially  different from the  forward-looking  statements.  When
reading  any of these  documents,  you  should  consider  all of the  risks  and
uncertainties that are discussed, and you should not rely on any forward-looking
statements made by UMB.

      Factors that could cause actual  results to be materially  different  from
forward-looking  statements  include:  (1)  interest  rate,  market and monetary
fluctuations;  (2) monetary and fiscal  policies and laws;  (3)  inflation;  (4)
general  economic  conditions;  (5) competition  and economic  conditions in UMB
regions and industries; (6) new products; (7) mergers and acquisitions;  and (8)
the ability of UMB to manage these and other risks.

      In addition,  you should  consider the  following  risks  relating to Plan
participation:

      You will not know the price at which you will be purchasing shares under
      the Plan until several days after you have made an investment decision.

      If you elect to make  optional cash  payments,  you must send funds to the
Plan  Administrator  at  least  two  (2)  business  days  prior  to the  related
investment date. Between the time that you decide to purchase shares through the
Plan  and the  time of  actual  purchase,  the  price of UMB  common  stock  may
fluctuate,  or other  information may become  available to you that would affect
your investment decision. Accordingly, you bear the risk of buying shares of UMB
common  stock  through  the Plan at prices  higher than you would  otherwise  be
willing to pay, or under  circumstances  in which you would otherwise not invest
in shares of UMB common stock.

     The price of UMB  stock may  decline  between  the time you  decide
     to sell shares of stock in your Plan  account and the time that your
     shares are sold.

     Direct participation in the Plan requires that you register shares of your
stock with the Plan  Administrator.  If you decide to sell your shares,  you may
request  the  Plan  Administrator  either  to  sell  your  shares  or  to  issue
certificates  to you so that you may  engage a broker to sell


                                       18



your shares.  The Plan  Administrator may take up to thirty (30) days to satisfy
your request. If the market price of UMB common stock declines during that time,
you will have lost the  opportunity to sell your shares at the highest  possible
price. If you have enrolled in dividend reinvestment,  you may not withdraw less
than five (5) business days before a dividend record date.

      You will not be able to direct the time or price at which the Plan
      Administrator sells your shares.

      If you request the Plan Administrator to sell the shares held in your Plan
account,  you will not be able to direct the time or price at which your  shares
are sold.  Although  the Plan  Administrator  will attempt in good faith to sell
your shares  without  delay,  UMB cannot assure you that the Plan  Administrator
will be able to sell your shares at the highest  possible price.  Moreover,  the
Plan  Administrator may sell your shares at a price that is lower than the price
at which you would otherwise prefer to sell your shares.

      No interest will be paid on dividends or optional cash payments until
      such money is reinvested or invested, as the case may be.

      UMB will not pay  interest on your  dividends  or optional  cash  payments
until such money is reinvested or invested. As noted above, if you elect to make
optional cash payments of more than $3,000 a calendar quarter,  and your request
for a waiver is not  granted,  such  payments  will be  returned  to you without
interest,  unless UMB  approves  your  request to purchase  more than $3,000 per
quarter.

                                  LEGAL OPINION

      In connection with the original registration  statement filed with the SEC
on November 14, 1995,  UMB's legal counsel passed on certain  matters related to
the shares of common stock to be purchased  pursuant to the Plan.  No additional
shares are being registered pursuant to this Prospectus Supplement No. 1.

                                 INDEMNIFICATION

      Section  355 of the  General  and  Business  Corporation  Law of  Missouri
provides  for the  indemnification  of directors  and  officers of  corporations
organized thereunder in certain  circumstances.  Such Section 355 grants to each
such  corporation  the power to indemnify  its  directors  and officers  against
liability  for certain of their acts.  UMB's bylaws  provide that  directors and
officers of UMB shall be indemnified to the fullest extent permitted by the laws
of the State of Missouri against liability for certain of their acts. Insofar as
indemnification  for  liabilities  arising under the  Securities Act of 1933, as
amended (the "Act"),  may be permitted to


                                       19


directors,  officers and  controlling  persons of UMB pursuant to the  foregoing
provisions  or  otherwise,  UMB has been informed that in the opinion of the SEC
such  indemnification  is against  public  policy as expressed in the Act and is
therefore unenforceable.
