PERFORMANCE SUMMARY

   Net income for Mercantile Bancorporation Inc. ("Corporation" or
   "Mercantile") in the first quarter of 1997 was $60,336,000 compared with
   the $4,565,000 earned in the same period a year ago and earnings per common
   share was $1.00 compared with $.07 in the first quarter of 1996. To allow
   comparison of the fundamental financial performance of Mercantile for 1997
   with 1996, it is helpful to exclude $40,012,000 of nonrecurring acquisition
   costs from the first quarter 1996 results of operations. Exhibit 2 presents
   those 1996 results adjusted for such nonrecurring expense and as shown, net
   income for 1997 was $15,759,000 or 35.4% higher than 1996 adjusted earnings.
   On a per common share basis, net income was $1.00 compared with the adjusted
   $.70 earned in last year's first quarter. Return on average assets increased
   to 1.29% in 1997 compared with 1.00% in 1996, while return on average equity
   improved to 15.06% from 10.65% last year.

   Financial Accounting Standard ("FAS") 128, "Earnings per Share," was
   issued in February 1997. This statement is effective in the fourth quarter
   of 1997 and requires additional reporting of earnings per share which gives
   effect to dilutive common shares such as stock options or convertible notes.
   The Corporation does not anticipate a significant impact when reporting
   diluted earnings per share.

   Exhibit 3 details acquisitions completed during 1996 and 1997 as well as two
   pending acquisitions. On March 5, 1997, the Corporation acquired Regional
   Bancshares, Inc., ("Regional"), a $172 million-asset bank holding company
   headquartered in Alton, Illinois. Two significant St. Louis-based mergers
   were announced in late 1996. On October 27, 1996, a definitive merger
   agreement was executed with Mark Twain Bancshares, Inc. ("Mark Twain"), a
   $3.2 billion-asset commercial banking organization with 41 offices in
   Missouri, Kansas and Illinois. The Mark Twain transaction closed on April
   25, 1997 and was accounted for as a pooling-of-interests, with resulting
   restatement of pre-acquisition accounts and results of operations. The
   estimated restated earnings per common share for the first quarter of 1997
   is $.98 compared with the $1.00 originally reported. During the second
   quarter of 1997, Mercantile expects to record nonrecurring acquisition
   charges related to the Regional and Mark Twain acquisitions which will
   reduce pre-tax income by $44,000,000 to $54,000,000.

   On December 23, 1996, the Corporation announced that a merger agreement had
   been signed with Roosevelt Financial Group, Inc. ("Roosevelt"),
   headquartered in St. Louis, Missouri. Roosevelt is a $7.5 billion-asset
   savings and loan holding company with 81 locations in Missouri, Kansas and
   Illinois. The merger with Roosevelt, which will be accounted for as a
   purchase, is expected to be completed in mid-1997 with branch consolidation
   of the combined entities to occur the following year. Pre-tax nonrecurring
   acquisition charges associated with the Roosevelt transaction of $38,000,000
   to $45,000,000 will be recorded at closing.

   Net interest income for the first quarter of 1997 was $179,515,000 compared
   with $169,736,000 in the year-earlier period, an increase of 5.8%. The net
   interest rate margin was 4.27% compared with 4.34% in the fourth quarter of
   1996 and 4.23% last year. Average earning assets of $17.1 billion grew 4.5%
   from $16.4 billion in the first quarter of 1996, as average loan volume
   increased 8.7%. This loan growth was funded through an increase in average
   core deposits and a decline in investment securities.

   Other income was $75,515,000 in the first quarter of 1997, an increase of
   27.4% from a year ago. Included in 1996's first quarter was $3,082,000 in
   nonrecurring securities losses which resulted from portfolio restructurings
   of recently acquired banks. Excluding these securities losses, other income
   increased by 21.1% over 1996. Growth in core fee businesses, such as the
   trust and investment areas, deposit service charges, credit card related
   revenues and fees earned in the electronic funds transfer processing
   business accounted for the strong growth.

   Non-interest expenses in 1997 were $143,686,000, 21.4% lower than in 1996.
   Excluding $41,678,000 in nonrecurring merger-related costs, total other
   expense in 1997 was $2,594,000 or 1.8% higher than a year ago. The
   efficiency ratio improved to 55.57% compared with the adjusted 59.78% of
   last year, and the other expense to average assets ratio was 3.07% compared
   with 3.16% in the first quarter of 1996. On April 3, 1996, the Corporation
   announced plans to reduce its bank charters by approximately 80% through
   consolidations during the next year in order to achieve greater operational
   efficiencies. In total, the Corporation's number of chartered banks dropped
   from 74 early in 1996 to 29 at March 31, 1997, and further consolidations
   are scheduled for 1997.

   The provision for possible loan losses for the quarter was $18,198,000
   compared with $33,168,000 in 1996. The first quarter of 1996 included
   $10,851,000 in nonrecurring merger-related provision and $10,000,000 which
   was recorded to offset a charge-off on a specialty retailer credit. Net
   charge-offs for 1997 and 1996 were $18,379,000 and $25,478,000,
   respectively, and on an annualized basis were .57% of average loans this
   quarter compared with .86% last year. At March 31, 1997, the reserve for
   possible loan losses was $198,061,000, and provided coverage of 269.13% of
   non-performing loans compared with 313.02% at year-end 1996 and 259.41% last
   March 31.

   Non-performing loans (i.e., non-accrual and renegotiated loans) as of March
   31, 1997 were $73,592,000 or .57% of total loans compared with the year-end
   1996 figures of $62,816,000 or .49% and $81,573,000 or .69% at March 31,
   1996. Foreclosed assets were $14,962,000 at March 31, 1997 and did not
   change substantially from year-end 1996.

   Consolidated assets of $18.9 billion were up 5.8% from last March 31. Core
   deposits increased by 5.6% to $13.5 billion, loans were up 9.9% to $13.0
   billion, and shareholders' equity of $1.6 billion was 2.9% lower than at
   March 31, 1996, reflecting the impact of treasury share purchases. All
   measures of capital adequacy remained strong. Tier I capital to risk-
   adjusted assets was 11.21% while Total capital to risk-adjusted assets at
   March 31, 1997 was 14.09%. On a pro forma basis after all announced
   acquisitions are closed, consolidated assets of Mercantile will approximate
   $30 billion.

   The following financial commentary presents a more thorough discussion and
   analysis of the results of operations and financial condition of the
   Corporation for the first quarter of 1997.

NET INTEREST INCOME

   Net interest income for the first quarter of 1997 was $179,515,000, a 5.8%
   increase from the $169,736,000 earned last year. The net interest rate
   margin was 4.27% compared with 4.23% in 1996. Continued competitive pricing
   for both loans and deposits was prevalent in both quarters and impacted the
   margin. Average earning asset growth in 1997 was 4.5%, led by loan growth of
   8.7% and a contraction in the size of the investment portfolio and
   short-term investments.

   Investment securities averaged $4.1 billion in the first
   quarter of 1997, and declined by 5.6% from 1996 due to both
   maturities and sales. The held-to-maturity and available-for-
   sale portfolio at March 31, 1997 consisted of 82.93% in U.S. and other
   Government agency securities, including 26.40% in mortgage-related
   issues, 12.12% in state and municipal securities, and 4.95% of other
   miscellaneous securities. The comparable distribution at March 31, 1996
   was 83.79%, 13.02% and 3.19%, respectively. Included in other miscellaneous
   securities as of March 31, 1997 was $55,700,000 transferred from the credit
   card loan portfolio in accordance with FAS 125, "Accounting for Transfers
   and Servicing of Financial Assets and Extinguishments of Liabilities."

</TABLE>

   Loans on average grew by $1.0 billion or 8.7%. Affecting loan growth figures
   from 1996 to 1997 is the amount of loans added from acquisitions accounted
   for as purchases. Loans grew by approximately 5% excluding those from
   acquired companies. Including acquired balances, average commercial loans
   grew by $406,073,000 or 13.5%. Commercial loan growth occurred on a
   system-wide basis. Average commercial real estate mortgage loans increased
   by only $38,960,000 or 1.6%. Residential real estate mortgage loans averaged
   $4.3 billion in the first quarter of 1997, an increase of $493,563,000 or
   12.9% from the first quarter of 1996. Residential mortgage loans added from
   acquisitions, as well as continued customer preference for adjustable-rate
   mortgages which Mercantile generally retained on the balance sheet,
   accounted for the increase. Average credit card loans were at the same level
   as in the first quarter of 1996 while other consumer loans increased on
   average by $104,812,000 or 6.2%, due primarily to growth in indirect auto
   loans.

   Average core deposits increased by $572,303,000 or 4.5% over the first
   quarter of 1996; Mercantile was substantially core funded at 90.47% of total
   deposits and 77.50% of earning assets. Changes in average core deposits for
   the past five quarters are shown in the Consolidated Quarterly Average
   Balance Sheet on Page 19 of this report.

   Average non-interest bearing deposits grew by $346,558,000 or 17.0%. The
   United States Government is a significant cash management customer of
   Mercantile Bank N.A. and pays for services rendered via compensating
   balances. In the first quarter of 1996, approximately $400,000,000 of such
   compensating balances were withdrawn by the government to help finance its
   funding requests due to the lack of an approved 1996 fiscal budget at that
   time. Accruals were made in 1996 to record the benefit of those missing
   deposits to better match revenue with services delivered. These balances
   were redeposited the second quarter of 1996.

   Average short-term borrowings increased by $154,162,000 or 10.7% in the
   first quarter of 1997, to replace the decline in bank notes outstanding.
   Average long-term debt increased by $70,897,000 due to the issuance of
   $150,000,000 of floating-rate capital trust securities in February 1997 net
   of a reduction in FHLB advances.

   The factors discussed previously are consistent with Mercantile's overall
   corporate policy relative to rate sensitivity and liquidity, which is to
   produce the optimal yield and maturity mix consistent with interest rate
   expectations and projected liquidity needs. The Consolidated Quarterly
   Average Balance Sheet, with rates earned and paid, is summarized by quarter
   on Page 19.

OTHER INCOME

   Non-interest income increased by 27.4% during the first quarter of 1997 to
   $75,515,000. Trust fees, service charges, investment banking and brokerage
   fees, credit card related revenue and cash management revenues were at
   higher levels than last year, while mortgage banking and letters of credit
   revenues declined. The first quarter of 1996 included $3,082,000 in
   nonrecurring merger-related securities losses compared with gains of
   $1,049,000 realized in 1997. Excluding non-interest income from companies
   acquired in purchase transactions and nonrecurring securities losses, other
   income grew by 19.0% from the first quarter of 1996. Service charges grew by
   6.1%, due largely to selective fee increases and enhanced pricing of low
   balance, high transaction accounts.

   Trust fees were the largest source of non-interest income in 1997, and were
   $20,991,000 compared with $19,354,000 during the first quarter of 1996, an
   increase of 8.5%. Personal trust fees earned by Mercantile Trust Company
   N.A. were the largest source of trust revenue and increased 15.1% from last
   year. Trust income from Mississippi Valley Advisors Inc., the investment
   management subsidiary of Mercantile, rose by 15.4%. Mississippi Valley
   Advisors Inc. manages the 15 Mercantile proprietary mutual funds--the ARCH
   funds. These funds had assets of $2.9 billion at March 31, 1997. Increases
   in the value of assets managed and successful new business development
   efforts largely accounted for the growth in trust fees, partially offset by
   the absence of fees from the indenture trust and agency business which was
   sold in the fourth quarter of 1996.

   Investment banking and brokerage fees were $3,410,000 compared with
   $3,143,000 last year, an increase of 8.5%. This income is largely
   volume-driven and is derived from transaction fees for services performed
   for both individual and corporate customers, including sales of annuities
   and mutual funds, profits earned on limited trading positions and foreign
   exchange revenue. Mark Twain will add significantly to this source of
   revenue in 1997.

   Credit card fee income was $5,345,000 for the first quarter of
   1997, compared with $1,449,000 last year. Credit card income
   primarily represents interchange fees received on transactions of
   Mercantile cardholders and cardholders' miscellaneous fees. This
   source of income in 1996 included $1,169,000 in fees charged to merchants
   for processing credit card transactions. The merchant processing business
   was sold late in the second quarter of 1996. Transaction-based rebates paid
   to SBC and MercRewards VISA cardholders are netted against credit card fee
   income; these rebates totaled $1,403,000 in the first quarter of 1997
   versus $6,6121,000 in 1996. The decrease in these rebates were the primary
   reason for the large growth in credit card fees over 1996.

</TABLE>

   Securitization revenue was $7,292,000 in the first quarter of 1997 versus
   $4,502,000 in 1996, and represents amounts accruing to Mercantile on the
   $400,000,000 in credit card loans securitized in the Mercantile Credit Card
   Master Trust during May 1995, as well as $2,200,000 recognized under FAS
   125 for investor certificate loans that were sold and reclassified to the
   investment portfolio. For securitized loans, amounts that would previously
   have been reported as interest income, interest expense, credit card fees
   and provision for loan losses are instead netted in non-interest income as
   securitization revenue. Because credit losses are absorbed against credit
   card servicing income over the life of these transactions, such income may
   vary depending upon the credit performance of the securitized loans. Higher
   levels of net charge-offs continued to adversely impact securitization
   revenue declined from 4Q96. Mercantile acts as servicing agent and receives
   loan servicing fees equal to two percent per annum of the securitized
   receivables. As servicing agent,

                                      13

<PAGE> 13
   Mercantile continues to provide customer service to collect past due
   accounts and to provide other services typically performed for its
   customers. Accordingly, Mercantile's relationship with its credit card
   customers is not affected by the securitization.

   Mortgage banking income decreased by $392,000 or 12.6% from the first
   quarter of 1996, largely due to a decline in gains recognized on the sale of
   loans. Mortgages serviced totaled $5.9 billion at March 31, 1997 compared
   with $5.4 billion at March 31, 1996. The Roosevelt transaction will add
   approximately $8.4 billion to servicing volume, and should increase
   servicing fees significantly in the last half of 1997.

   Miscellaneous income of $14,254,000 was 25.0% higher than in 1996, due
   primarily to a $2,900,000 improvement in cash management fees and $500,000
   recorded for loan syndication fees in the current quarter, partially offset
   by a decline in letters of credit fees.

OTHER EXPENSE

   Expenses other than interest expense and the provision for possible loan
   losses for the first quarter of 1997 totaled $143,686,000, a decrease of
   $39,084,000 or 21.4% from 1996. Included in other expense in the first
   quarter of 1996 was $41,678,000 in expenses associated with mergers, largely
   for investment banking and other professional services, change in control
   and severance payments, transition and duplicative costs related to system
   standardization and signage, and obsolete equipment write-offs. Excluding
   nonrecurring merger costs, total operating expenses increased by 1.8% over
   1996, and were 3.07% of average assets compared with 3.16% last year. The
   efficiency ratio, defined as operating expenses as a percentage of
   taxable-equivalent net interest income and other income, was 55.57% versus
   59.78% last year.

   Other expense from acquisitions accounted for as purchases increased the
   Corporation's expenses by more than $4,000,000. If expense from acquired
   banks in 1997 and nonrecurring acquisition expense in 1996 are excluded,
   1997 non-interest expense was 1.3% lower than in 1996.

   Salary expenses increased by 6.2% during the first quarter,
   largely reflecting the costs of merit increases and compensation
   for employees added in acquisitions. Benefit costs were up by 5.2%
   due to higher costs of employee benefit programs, a larger salary base
   and more employees. Occupancy and equipment costs increased by 9.3%
   in the first quarter, reflecting the costs of maintaining additional
   offices, costs associated with modifying computer application systems
   for the year 2000, and an ongoing program of upgrading systems and
   equipment to further enhance productivity.

   Exhibit 6 details the composition of all other operating expenses. Credit
   card fees declined by $1,379,000 or 36.0% due primarily to the costs
   associated with the merchant processing business which was sold in the
   second quarter of 1996. Other expense declined largely due to cash
   recovered on transactions recognized as expenses in prior accounting
   periods. Intangible asset amortization was $4,117,000 in the first quarter
   of 1997, 55.6% higher than in 1996. The increase was caused by additional
   amortization on goodwill recorded in 1996 purchase acquisitions.

RESERVE FOR POSSIBLE LOAN LOSSES

   The reserve for possible loan losses was $198,061,000 or 1.52% of loans
   outstanding at March 31, 1997. This compared with $196,627,000 or 1.54% at
   year's end and $211,608,000 or 1.79% at March 31, 1996. The reserve coverage
   of non-performing loans was 269.13% compared with 313.02% at year-end and
   259.41% last year. One-third of the Corporation's total loan portfolio is
   invested in residential real estate loans for which the loan loss experience
   averaged only .06% for the past five years. If those loans are excluded from
   total loans, the reserve for possible loan losses represented 2.30% of loans
   outstanding at March 31, 1997.

   The provision for possible loan losses for the first quarter of
   1997 was $18,198,000 compared with $33,168,000 last year.
   The first quarter of 1996 included a nonrecurring merger-
   related provision of $10,851,000, which was recorded largely
   to conform the credit policies of recently acquired entities to
   those of Mercantile. An additional $10,000,000 in provision
   was recorded in the first quarter of 1996 to offset an
   $11,000,000 charge-off of a credit to a St. Louis-based spe-
   cialty retailer that declared bankruptcy in late 1995. The
   annualized ratio of net charge-offs to average loans for the
   first quarter was .57% compared with .86% last year, while
   the corresponding net charge-off figures were $18,379,000 and
   $25,478,000, respectively.

   Excluding securitized credit cards, net credit card charge-
   offs were $16,886,000 in 1997 versus $13,447,000 last year,
   which represented 8.24% of average credit card loans for this
   quarter compared with 6.46% in 1996. On the managed portfolio,
   the ratio of net charge-offs to average loans was 8.42%
   versus 7.36% in the first quarter of 1996. By credit policy,
   losses are taken on credit card loans after six cycles of
   nonpayment, or within 15 days of receipt of personal bank-
   ruptcy notice, if earlier. Approximately 37% of the 1997
   year-to-date losses were a result of bankruptcy claims. Ex-
   cluding credit card net charge-offs, net charge-offs were only
   $1,493,000 or .05% of average loans for the first quarter of 1997.

   Mercantile evaluates the reserve for loan losses on a quarterly basis to
   ensure the timely charge-off of loans and to determine the adequacy of the
   reserve. Management believes the consolidated reserve of 1.52% of loans and
   269.13% of non-performing loans as of March 31, 1997 was adequate based on
   the risks identified at such date in the portfolio.

NON-PERFORMING ASSETS

   Non-performing loans (non-accrual and renegotiated loans)
   were $73,592,000 or .57% of total loans at March 31, 1997,
   compared with $62,816,000 or .49% at December 31, 1996
   and $81,573,000 or .69% at March 31, 1996. By the Corpora-
   tion's definition, all non-accrual and renegotiated commer-
   cial-related loans are considered impaired as defined by FAS
   114, "Accounting by Creditors for Impairment of a Loans,"
   as amended by FAS 118. Impaired loans totaled $41,190,000
   at March 31, 1997 and averaged $34,869,000 for the quarter.
   Foreclosed assets were $14,962,000 at March 31, 1997 com-
   pared with $13,345,000 at year's end and $10,102,000 last
   year. The ratio of non-performing assets to outstanding
   loans and foreclosed assets was .68% at March 31, 1997
   compared with .60% at December 31, 1996 and .77% last
   year.

   Non-accrual loans, while declining $7,697,000 or 9.8% from
   March 31, 1996, increased $10,840,000 from December 31,
   1996. The increase was largely the result of the reclassifica-
   tion in two asset-based performing loans to non-accrual
   status and $1,962,000 added from the Regional acquisition.
   As of March 31, 1997, Mercantile had only seven non-
   accrual loans with balances in excess of $1,000,000. The
   largest non-accrual loan had a balance of less than
   $5,500,000. As significant, the Corporation held only two
   foreclosed assets with a book value in excess of $1,000,000,
   the largest being less than $3,500,000.

   All loans classified as renegotiated were paying in accor-
   dance with their modified terms at March 31, 1997. Loans
   past due 90 days and still accruing interest consisted largely
   of credit card loans, consumer loans and residential real
   estate mortgage loans.

  CAPITAL RESOURCES

   Mercantile maintains a strong capital base, which provides a solid
   foundation for anticipated future asset growth and promotes depositor and
   investor confidence. Capital management is a continuous process at
   Mercantile and is focused on ensuring that adequate capital is provided for
   both current needs and anticipated growth. This strategy has enabled
   Mercantile to profitably expand its balance sheet, while maintaining capital
   ratios which exceed minimum capital requirements.

   At March 31, 1997, shareholders' equity was $1.6 billion, a managed decline
   of 2.9% from March 31, 1996. Since December 31, 1996, the Corporation
   repurchased 2,309,033 shares of its common stock via designated
   broker-dealers at an average cost of $55.88 per share. A small portion of
   that stock was held for reissuance in conjunction with the 1994 Stock
   Incentive Plan, while the remainder was held for future reissuance in the
   Roosevelt transaction. The net fair value adjustment on available-for-sale
   securities reduced shareholders' equity by $8,923,000 in the first quarter
   of 1997, and $28,700,000 was added to equity with the Regional
   acquisition. Exhibit 9 details all significant capital ratios.

<PAGE> 16
   On July 11, 1996, the Board of Directors authorized the repurchase
   of up to 6,000,000 shares of the Corporation's common stock. This
   authorization was inclusive of shares to be repurchased in connection
   with previously announced pending acquisitions. In conjunction with
   the Mark Twain pooling transaction, the Board rescinded this program.
   Mercantile currently has authorization to repurchase up to 7,000,000 shares
   for reissuance in the Roosevelt transaction. To partially fund the announced
   treasury share repurchase, the Corporation formed Mercantile Capital
   Trust I on January 29, 1997. Through this trust, Mercantile obtained
   $150,000,000 of floating-rate debt which, for regulatory purposes, is
   part of Tier I capital. Up to $500 million in senior and/or subordinated
   debt securities will likely be raised in the first half of 1997,
   primarily to finance the Roosevelt acquisition.

                          PART II--OTHER INFORMATION

Item 4.  Submission of Matters to a Vote of Security Holders

   The annual meeting of shareholders of Registrant was held on April 24,
   1997.  Of 60,209,008 shares issued, outstanding and eligible to be
   voted at the meeting, 47,544,778 shares, constituting a quorum, were
   represented in person or by proxy at the meeting.  Six (6) matters were
   submitted to a vote of the security-holders at the meeting.

   1.  ELECTION OF CLASS III DIRECTORS.  The first matter submitted
   was the election of three Class III director nominees to the Board of
   Directors, each to continue in office until the year 2000.  The
   Restated Articles of Incorporation of the Registrant allow cumulative
   voting in all director elections and all shareholders were accordingly
   allowed to cumulate their votes for directors if they so desired.  Upon
   tabulation of the votes cast, it was determined that all three director
   nominees had been elected.  The voting results are set forth below:

      Patrick T. Stokes         47,165,135           310,920
</TABLE>

   2.  ELECTION OF CLASS II DIRECTOR.  The second matter submitted to
   the shareholders was the election of one director nominee, Craig D.
   Schnuck, to the Board of Directors in Class II, to continue in office
   until 1999.  Mr Schnuck was previously elected and served as a Class
   III director.  His term as a Class III director expired as of the 1997
   annual meeting.  Mr. Schnuck stood for election at the 1997 annual
   meeting in Class II.  Because only one director stood for election in
   Class II, cumulative voting was not applicable.  Upon tabulation of the
   votes cast it was determined that Mr. Schnuck had been elected.  The
   voting results are set forth below:

<TABLE>

</TABLE>

   Because Registrant has a staggered Board, the term of office of the
   following named Class I and Class II directors, who were not up for
   election at the 1997 annual meeting, continued after the meeting:

   Class I (to continue in office until 1998)

    Thomas A. Hays            Harvey Saligman         John A. Wright
    Frank Lyon, Jr.           Robert L. Stark

   Class II (to continue in office until 1999)

    William A. Hall           Robert W. Murray
    Edward A. Mueller

   SARs to 1,200,000 shares,  was approved by a vote of a majority of the
   shares of the Registrant's Common Stock present and voting at the

                                    -2-
<PAGE> 5

initial Class III Directors shall expire at the annual meeting of
shareholders of the Corporation in 1988; or in each case until
their respective successors are duly elected and qualified.  At
each annual election held after 1985 the Directors chosen to
succeed those whose terms then expire shall be identified as
being of the same class as the Directors they succeed and shall
be elected for a term of three (3) years expiring at the third
succeeding annual meeting or thereafter until their respective
successors are duly elected and qualified.  If the number of
Directors is changed, any increase or decrease in the number of
Directors shall be apportioned among the classes so as to
maintain the number of Directors in each class as nearly equal as
possible.  Any Director elected to fill a vacancy in any class
(whether such vacancy is caused by death, resignation, or
removal, or by an increase in the number of Directors in such
class) shall hold office for a term which shall expire with the
term of the Directors in such class.  At a meeting called
expressly for that purpose, the entire Board of Directors, or any
individual Director or Directors, may be removed without cause,
only upon the affirmative vote of the holders of at least
seventy-five percent (75%) of the total votes to which all of the
shares then entitled to vote at a meeting of shareholders called
for an election of Directors are entitled; provided, however,
that, if less than the entire Board of Directors is to be so
removed without cause, no individual Director may be so removed
if the votes cast against such Director's removal would be
sufficient to elect such Director if then cumulatively voted at
an election of the class of Directors of which such Director is a
part.  At a meeting called expressly for that purpose, any
Director may be removed by the shareholders for cause by the
affirmative vote of the holders of a majority of the shares
entitled to vote upon his election.

     B. Vote Required for Amendment.  In addition to any
        ----------------------------
affirmative vote required by law or otherwise, any amendment,
alteration, change or repeal of the provisions of this Article 6
shall require the affirmative vote of the holders of at least
seventy-five percent (75%) of the total votes to which all of the
shares then entitled to vote at a meeting of shareholders called
for an election of Directors are entitled, unless such amendment,
alteration, change or repeal has previously been expressly
approved by the Board of Directors of the Corporation by the
affirmative, vote or consent of at least sixty-six and two-thirds
percent (66 2/3%) of the number of Directors then authorized by,
or in the manner provided in, the By-laws, in which case the
shareholder vote required by this Section B of Article 6 shall
not apply.

           ----------------------------------------
to any affirmative vote required by law, and except as otherwise
expressly provided in Section B of this Article 13, a Business

together as a Single class (it being understood that for the
purposes of this Article 13, each share of the voting stock shall

          located, and on any of she businesses and properties of
          the Corporation and its subsidiaries, and

          (2)  the adequacy of the consideration offered in
          relation not only to the current market price of the
          outstanding securities of the Corporation but also to
          the current value of the Corporation in a freely
          negotiated transaction and the Board

     The Executive Committee of the Board of Directors of the
Company (the "Company Board") has determined that it is in the

the Company will have the dedication of the Executive pending the
merger of Mark Twain Bancshares, Inc. ("Mark Twain") and the
Company (the "Merger") pursuant to the Agreement and Plan of
Merger dated as of October 27, 1996, and to provide the surviving
corporation after the Merger with continuity of management.

     1.  Effective Date.  The "Effective Date" shall mean the
         ---------------
date on which the Effective Time of the Merger (as defined in the

mutually agreed upon by the Company and Mark Twain.

         ------------------
continue the Executive in its employ, and the Executive hereby
agrees to remain in the employ of the Company subject to the
terms and conditions of this Agreement, for the period commencing
on the Effective Date and ending eighteen months after such date
(the "Employment Period").  In addition, the Company hereby
agrees to nominate the Executive for election to the Board of
Directors of the Company for a three-year term expiring in 2000.

     3.  Terms of Employment.  (a) Position and Duties.  (i)

During the Employment Period, (A) the Executive shall serve as
Chairman of the Board of Directors of the Company's St, Louis
banking affiliate ("Bank") and (B) the Executive's services shall
be performed in St. Louis.

               (ii)  During the Employment Period, and excluding
any periods of vacation and sick leave to which the Executive is
entitled, and recognizing that Executive is involved in other
non-related business activities, the Executive agrees to be
available from time to time to devote reasonable attention to the
business and affairs of the Bank, including governance of its
Board and business development endeavors.

          (b)  Compensation.  (i) Base Salary.  During the
               -------------      ------------
Employment Period, the Executive shall receive an annual base
salary ("Annual Base Salary") of no less than $420,000.  Any
increase in Annual Base Salary shall not serve to limit or reduce
any other obligation to the Executive under this Agreement.

and the term Annual Base Salary as utilized in this Agreement
shall refer to Annual Base Salary as so increased.  As used in
this Agreement, the term "affiliated

in addition to Annual Base Salary, the Executive will be eligible
to receive, (I) for each fiscal year during which the Executive
is employed, an annual bonus (the "Annual Bonus") in an amount to
be determined by the Company Board of Directors, but in no event
shall the amount of the Annual Bonus during the first fiscal year
during which the Executive is employed (the "First Fiscal Year")
be less than $231,000 (the "Minimum Bonus") and (II) for that
portion of any fiscal year other than the First Fiscal Year
during which the Executive is employed for less than twelve full
months, an amount equal to the product of (x) the greater of (A)
the Minimum Bonus and (B) any other Annual Bonus paid to the
Executive during the Employment Period, and (y) a fraction, the
numerator of which is the number of days in such fiscal year
during which the Executive is employed by the Company, and the
denominator of which is 365.  Each such Annual Bonus shall be
paid in cash in a manner and at a time in accordance with the
Company's customary practices with respect to other peer
executives of the Company.  The Annual Bonus with respect to
fiscal year 1997 shall be paid no later than January 31, 1998.

               (iii)  Incentive Savings and Retirement Plans.

peer executives of the Company and its affiliated companies.

               (iv)  Welfare Benefit Plans.  During the
                     ----------------------
Employment Period, the Executive and/or the Executive's family,

                     ----------------
period, the Executive shall be entitled to fringe benefits on a
basis no less favorable than that applicable to other peer
executives of the Company and its affiliated companies, and also,
to the extent that the Executive receives such fringe benefits as
of the date hereof, payment of club dues and use of an automobile
and payment of related expenses.

               (vii)  Office and Support Staff.  During the

that applicable to other peer executives of the Company and its
affiliated companies.

     4.  Termination of Employment.  (a) Death or Disability.
         --------------------------      --------------------
The Executive's employment shall terminate automatically upon the
Executive's death during the Employment Period.  If the Company
determines in good faith that the Disability of the Executive has
occurred during the Employment Period (pursuant to the definition
of Disability set forth below), it may give to the Executive
written notice in accordance with Section 12(b) of this Agreement
of its intention to terminate the Executive's employment.  In
such event, the Executive's employment with the Company shall
terminate effective on the 30th day after receipt of such notice
by the Executive (the "Disability Effective Date"), provided
that, within the 30 days after such receipt, the Executive shall
not have returned to full-time performance of the Executive's
duties.  For purposes of this Agreement, "Disability" shall mean
the absence of the Executive from the Executive's duties with the
Company or Bank on a full-time basis for 180 consecutive business
days as a result of incapacity due to mental or physical illness
which is determined to be total and permanent by a physician
selected by the Company or its insurers and acceptable to the
Executive or the Executive's legal representative.

          (b)  Cause. The Company or Bank may terminate the
               ------
Executive's employment during the Employment Period for Cause.
For purposes of this Agreement, "Cause" shall mean:

               (i)  The Executive's willful and continued failure
to substantially perform his duties (other than as a result of
incapacity due to physical or mental condition), after a written
demand for performance is delivered to the Executive which
specifically identifies the manner in which the Executive has not
substantially performed his duties; or

               (ii)  The Executive's willful commission or
misconduct which is materially injurious to the Company and/or
Bank, monetarily or otherwise; or

               (iii)  Conviction of the Executive of a felony; or

               (iv)  A determination by the Company or Bank that
the Executive has committed fraud, embezzlement, theft, or
misappropriation against or from the Company or Bank; or

                                    3
<PAGE> 5

               (v)  The Executive's material breach of any
provision of this Agreement, including any breach of Section 10.

For purposes of this Section, no act or failure to act shall be
considered "willful" unless done or omitted to be done without
good faith and without a reasonable belief that the act or
omission was in the best interest of the Company and/or Bank.

          (c)  Good Reason.  The Executive's employment may be
               ------------
terminated by the Executive for Good Reason.  For purposes of
this Agreement, "Good Reason" shall mean a termination by the
Executive following a material breach of this Agreement by the
Company that is not cured after reasonable notice of such breach.

          (d)  Notice of Termination.  Any termination by the
               ----------------------
Company or Bank for Cause, or by the Executive for Good Reason,
shall be communicated by Notice of Termination to the other party
hereto given in accordance with Section 12(b) of this Agreement.
For purposes of this Agreement, a "Notice of Termination" means a
written notice which (i) indicates the specific termination
provision in this Agreement relied upon, (ii) to the extent
applicable, sets forth in reasonable detail the facts and
circumstances claimed to provide a basis for termination of the
Executive's employment under the provision so indicated and (iii)
if the Date of Termination (as defined below) is other than the
date of receipt of such notice, specifies the termination date
(which date shall be not more than thirty days after the giving
of such notice).  The failure by the Executive, the Company or
Bank to set forth in the Notice of Termination any fact or
circumstance which contributes to a showing of Good Reason or
Cause shall not waive any right of the Executive, the Company or
Bank, respectively, hereunder or preclude the Executive, the
Company or Bank, respectively, from asserting such fact or
circumstance in enforcing the Executive's, the Company's or
Bank's rights hereunder.

          (e)  Date of Termination.  "Date of Termination" means
               --------------------
(i) if the Executive's employment is terminated by the Company or
Bank for Cause, or by the Executive for Good Reason, the date of
receipt of the Notice of Termination or any later date specified
therein, as the case may be, (ii) if the Executive's employment
is terminated by the Company or Bank other than for Cause or
Disability, the Date of Termination shall be the date on which
the Company or Bank notifies the Executive of such termination
and (iii) if the Executive's employment is terminated by reason
of death or Disability, the Date of Termination shall be the date
of death of the Executive or the Disability Effective Date, as
the case may be.

     5.  Obligations of the Company upon Termination.  (a) Good
         --------------------------------------------      ----
Reason; Other Than for Cause, Death or Disability.  If, during
- --------------------------------------------------
the Employment Period, the Company or Bank shall terminate the
Executive's employment other than for Cause, Death or Disability
or the Executive shall terminate employment for Good Reason,
then, subject to Section 6 of this Agreement:

                                    4
<PAGE> 6

               (i)  The Company shall pay to the Executive the
aggregate of the following amounts:

               A.  The sum of (1) the Executive's Annual Base
Salary through the Date of Termination to the extent not
theretofore paid ("Accrued Salary") and (2) the product of (x)
the Annual Bonus paid or payable, including any bonus or portion
thereof which has been earned but deferred (and annualized for
any fiscal year consisting of less than twelve full months or
during which the Executive was employed for less than twelve full
months), for the most recently completed fiscal year during the
Employment Period, if any, or, in the event that a fiscal year
has not been completed during the Employment Period as of the
Date of Termination, the Minimum Bonus, and (y) a fraction, the
numerator of which is the number of days in the current fiscal
year through the Date of Termination and the denominator of which
is 365 (the sum of the amounts described in clauses (1) and (2)
shall be hereinafter referred to as the "Accrued Obligations");
and

               B.  The greater of (1) the amount equal to the
product of (i) the number of months remaining in the Employment
Period on the Date of Termination (the "Continuation Period"),
divided by twelve and (ii) the sum of (x) the Executive's Annual
Base Salary and (y) the Annual Bonus paid or payable for the most
recently completed fiscal year during the Employment Period (the
"Recent Annual Bonus"), or, in the event that a fiscal year has
not been completed during the Employment Period as of the Date of
Termination, the Minimum Bonus, and (2) the amount equal to the
sum of (x) the Executive's Annual Base Salary and (y) the Recent
Annual Bonus, payable in 24 equal monthly installments (as
appropriate, the "Termination Payment");

               (ii)  For the greater of (1) one year or (2) the
Continuation Period, or such longer period as may be provided by
the terms of the appropriate plan, program, practice or policy,
the Company shall after the Executive's Date of Termination
continue benefits to the Executive and/or the Executive's family
at least equal to those which would have been provided to them in
accordance with the plans, programs, practices and policies
described in Section 3(b)(iv) of this Agreement if the
Executive's employment had not been terminated or, if more
favorable to the Executive, as in effect generally at any time
thereafter with respect to other peer executives of the Company
and its affiliated companies and their families;

               (iii)  To the extent not theretofore paid or
provided, the Company shall timely pay or provide to the
Executive any other amounts or benefits required to be paid or
provided or which the Executive is eligible to receive under any
plan, program, policy or practice or contract or agreement of the
Company and its affiliated companies (such other amounts and
benefits shall be hereinafter referred to as the "Other
Benefits").

          (b)  Death.  If the Executive's employment is
               ------
terminated by reason of the Executive's death during the
Employment Period, this Agreement shall terminate without further
obligations to the Executive's legal representatives under this
Agreement, other than

                                    5
<PAGE> 7

for payment of Accrued Obligations and the Termination Payment and the timely
payment or provision of Other Benefits.  Accrued Obligations and the
Termination Payment shall be paid to the Executive's estate or beneficiary, as
applicable, in a lump sum in cash within 30 days of the Date of Termination.
With respect to the provision of Other Benefits, the term Other
Benefits as utilized in this Section 5(b) shall include, without
limitation, and the Executive's estate and/or beneficiaries shall
be entitled to receive, benefits at least equal to the most
favorable benefits provided by the Company and affiliated
companies to the estates and beneficiaries of peer executives of
the Company and such affiliated companies under such plans,
programs, practices and policies relating to death benefits, if
any, as in effect with respect to other peer executives and their
beneficiaries at any time during the 120-day period immediately
preceding the Effective Date or, if more favorable to the
Executive's estate and/or the Executive's beneficiaries, as in
effect on the date of the Executive's death with respect to other
peer executives of the Company and its affiliated companies and
their beneficiaries.

          (c)  Disability.  If the Executive's employment is
               -----------
terminated by reason of the Executive's Disability during the
Employment Period, this Agreement shall terminate without further
obligation to the Executive, other than for payment of Accrued
Obligations, the Termination Payment and the timely payment or
provision of Other Benefits.  Accrued Obligations and the
Termination Payment shall be paid to the Executive in a lump sum
in cash within 30 days of the Date of Termination.  With respect
to the provision of Other Benefits, the term Other Benefits as
utilized in this section 5(c) shall include, and the Executive
shall be entitled after the Disability Effective Date to receive,
disability and other benefits in accordance with such plans,
programs, practices and policies relating to disability, if any,
as in effect generally with respect to other peer executives of
the Company and its affiliated companies and their families.

          (d)  Cause: Other than for Good Reason.  If the
               ----------------------------------
Executive's employment shall be terminated for Cause or by the
Executive other than for Good Reason during the Employment
Period, this Agreement shall terminate without further
obligations to the Executive other than the obligation to pay to
the Executive his Accrued Salary and Other Benefits, in each case
to the extent theretofore unpaid.

     6.  Non-exclusivity of Rights.  Nothing in this Agreement
         --------------------------
shall prevent or limit the Executive's continuing or future
participation in any plan, program, policy or practice provided
by the Company, or any of its affiliated companies and for which
the Executive may qualify, nor shall anything herein limit or
otherwise affect such rights as the Executive may have under any
contract or agreement with the Company or any of its affiliated
companies.  Amounts which are vested benefits or which the
Executive is otherwise entitled to receive under any plan,
policy, practice or program of or any contract or agreement with
the Company or any of its affiliated companies at or subsequent
to the Date of Termination shall be payable in accordance with
such plan, policy, practice or program or contract or agreement
except as explicitly modified by this Agreement.  In accordance
with the foregoing and not in limitation thereof the Executive
and his spouse shall be entitled to

                                    6
<PAGE> 8

medical coverage in accordance with the letter to the Executive from Keith
Miller attached hereto as Exhibit A and to retirement benefits in an
amount no less than those indicated on Exhibit B attached hereto.

     7.  Full Settlement.  The Company's obligation to make the
         ----------------
payments provided for in this Agreement and otherwise to perform
its obligations hereunder shall not be affected by any set-off,
counterclaim, recoupment, defense or other claim, right or action
which the Company may have against the Executive or others.  In
no event shall the Executive be obligated to seek other
employment or take any other action by way of mitigation of the
amounts payable to the Executive under any of the provisions of
this Agreement and such amounts shall not be reduced whether or
not the Executive obtains other employment.  The Company agrees
to pay as incurred, to the full extent permitted by law, all
legal fees and expenses which the Executive may reasonably incur
as a result of any contest (regardless of the outcome thereof) by
the Company, the Executive or others of the validity or
enforceability of, or liability under, any provision of this
Agreement or any guarantee of performance thereof (including as a
result of any contest by the Executive about the amount of any
payment pursuant to this Agreement), plus in each case interest
on any delayed payment at the applicable Federal rate provided
for in Section 7872(f)(2)(A) of the Internal Revenue Code of
1986, as amended (the "Code").

     8.  Certain Reduction of Payments by the Company.  (a) For
         ---------------------------------------------
purposes of this Section 8, (i) a "Payment" shall mean any
payment or distribution in the nature of compensation to or for
the benefit of the Executive, whether paid or payable pursuant to
this Agreement or otherwise; (ii) "Separation Payment" shall mean
a Payment paid or payable pursuant to this Agreement
(disregarding this Section); (iii) "Net After Tax Receipt" shall
mean the Present Value of a Payment net of all taxes imposed on
the Executive with respect thereto under Sections 1 and 4999 of
the Internal Revenue Code of 1986, as amended (the "Code"),
determined by applying the highest marginal rate under Section 1
of the Code which applied to the Executive's taxable income for
the immediately preceding taxable year; (iv) "Present Value"
shall mean such value determined in accordance with Section
280G(d)(4) of the Code; and (v) "Reduced Amount" shall mean the
greatest aggregate amount of Separation Payments which (a) is
less than the sum of all Separation Payments and (b) results in
aggregate Net After Tax Receipts which are equal to or greater
than the Net After Tax Receipts which would result if the
Executive were paid the sum of all Separation Payments.

          (b)  Anything in this Agreement to the contrary
notwithstanding, in the event KPMG Peat Marwick LLP or such other
nationally recognized certified public accounting firm designated
by the Executive (the "Accounting Firm") shall determine that
receipt of all payments would subject the Executive to tax under
Section 4999 of the Code, it shall determine whether some amount
of Separation Payments would meet the definition of a "Reduced
Amount." If the Accounting Firm determines that there is a
Reduced Amount, the aggregate Separation Payments shall be
reduced to such Reduced Amount.  All fees payable to the
Accounting Firm shall be paid solely by the Company.

                                    7
<PAGE> 9

          (c)  If the Accounting Firm determines that aggregate
Separation Payments should be reduced to the Reduced Amount, the
Company shall promptly give the Executive notice to that effect
and a copy of the detailed calculation thereof, and the Executive
may then elect, in his sole discretion, which and how much of the
Separation Payments shall be eliminated or reduced (as long as
after such election the present value of the aggregate Separation
Payments equals the Reduced Amount), and shall advise the Company
in writing of his election within ten days of his receipt of
notice.  If no such election is made by the Executive within such
ten-day period, the Company may elect which of such Separation
Payments shall be eliminated or reduced (as long as after such
election the present value of the aggregate Separation Payments
equals the Reduced Amount) and shall notify the Executive
promptly of such election.  All determinations made by the
Accounting Firm under this Section shall be binding upon the
Company and the Executive and shall be made within 60 days of a
termination of employment of the Executive.  As promptly as
practicable following such determination, the Company shall pay
to or distribute for the benefit of the Executive such Separation
Payments as are then due to the Executive under this Agreement
and shall promptly pay to or distribute for the benefit of the
Executive in the future such Separation Payments as become due to
the Executive under this Agreement.

          (d)  While it is the intention of the Company to reduce
the amounts payable or distributable to the Executive hereunder
only if the aggregate Net After Tax Receipts to an Executive
would thereby be increased, as a result of the uncertainty in the
application of Section 4999 of the Code at the time of the
initial determination by the Accounting Firm hereunder, it is
possible that amounts will have been paid or distributed by the
Company to or for the benefit of the Executive pursuant to this
Agreement which should not have been so paid or distributed
("Overpayment") or that additional amounts which will have not
been paid or distributed by the Company to or for the benefit of
the Executive pursuant to this Agreement could have been so paid
or distributed ("Underpayment"), in each case, consistent with
the calculation of the Reduced Amount hereunder.  In the event
that the Accounting Firm, based upon the assertion of a
deficiency by the Internal Revenue Service against the Company or
the Executive which deficiency the Accounting Firm believes has a
high probability of success, determines that an Overpayment has
been made, any such Overpayment paid or distributed by the
Company to or for the benefit of the Executive shall be treated
for all purposes as a loan to the Executive which the Executive
shall repay to the Company together with interest at the
applicable federal rate provided for in Section 7872(f)(2) of the
Code; provided, however, that no such loan shall be deemed to
have been made and no amount shall be payable by the Executive to
the Company if and to the extent such deemed loan and payment
would not either reduce the amount on which the Executive is
subject to tax under Section 1 and Section 4999 of the Code or
generate a refund of such taxes.  In the event that the
Accounting Firm, based upon controlling precedent or substantial
authority, determines that an Underpayment has occurred, any such
Underpayment shall be promptly paid by the Company to or for the
benefit of the Executive together with interest at the applicable
federal rate provided for in Section 7872(f)(2) of the Code.

                                    8
<PAGE> 10

     9.  Confidential Information.  The Executive shall hold in a
         -------------------------
fiduciary capacity for the benefit of the Company and Bank all
secret or confidential information, knowledge or data relating to
the Company or Bank or any of their affiliated companies, and
their respective businesses, which shall have been obtained by
the Executive during the Executive's employment by the Company or
any of its affiliated companies and which shall not be or become
public knowledge (other than by acts by the Executive or
representatives of the Executive in violation of this Agreement).
After termination of the Executive's employment, the Executive
shall not, without the prior written consent of the Company or as
may otherwise be required by law or legal process, communicate or
divulge any such information, knowledge or data to anyone other
than the Company and those designated by it.  In no event shall
an asserted violation of the provisions of this Section 9
constitute a basis for deferring or withholding any amounts
otherwise payable to the Executive under this Agreement.

     10.  Covenant Not To Engage in Competitive or Other
          ----------------------------------------------
Detrimental Activities.  (a)  The Executive covenants that from
- -----------------------
and after the Effective Date he will not compete with the
Company, Bank and/or their affiliates and further covenants that
he will not take any action which is detrimental to the Company,
Bank and/or their affiliates (i) during the Employment Period,
and (ii) if the Executive's employment terminates for any reason
(other than the Executive's death) or no reason during the
Employment Period, for an additional three (3) year period of
time beginning on the Date of Termination.

          (b)  For purposes of paragraph (a) of this Section 10,
the Executive shall be deemed to be competing with the Company,
Bank and/or their affiliates at any time if the Executive accepts
employment with, or serves as an agent, employee, or director of,
or a consultant to, a competitor of the Company, Bank and/or
their affiliates, or during such time the Executive acquires or
has an interest (direct or indirect) in any firm, corporation or
enterprise engaged in a business which is in competition with the
Company, Bank and/or their affiliates, or at any time, either
during employment or thereafter, the Executive divulges any
information concerning the Company, Bank and/or their affiliates
which is or could be of aid to any such competitor.  The mere
ownership of a less than a 3% debt and/or equity interest in a
competing company whose stock is publicly held shall not be
considered as having the prohibited interest in a competitor, and
neither shall the mere ownership of a less than a 10% debt and/or
equity interest in a competing company whose stock is not
publicly held.  For purposes of this Agreement, any commercial
bank, savings and loan association, securities broker or dealer,
or other business or financial institution that offers any major
service at the time offered by the Company, Bank and/or their
affiliates, and which conducts business in any location
encompassed within the areas circumscribed by circles, of which
the radii are 50 miles and the mid-points are the geographic
centers of Kansas City, Missouri, and St. Louis, Missouri, shall
be deemed to be a competitor,

          (c)  Should the Company reasonably believe that the
Executive has violated any of the foregoing provisions, it shall
give the Executive written notice to such effect, stating the
reason(s), for its belief, and pending a final determination as
to whether there has been a violation may, without penalty or
risk of claim for actual or punitive damages,

                                    9
<PAGE> 11

suspend payment of any further amount which might otherwise become payable
hereunder.  The Company shall, in an expeditious manner,
determine from all information available to it whether the
Executive violated any of the foregoing covenants, and if the
Company in good faith concludes that the Executive has violated
this Agreement, the Executive shall not be entitled to any
further payment hereunder.

          (d)  The Executive represents, acknowledges and agrees
(i) that his experience and capabilities are such that he can
obtain employment in activities which do not violate such
agreement and that the enforcement by way of injunction of the
agreement not to compete will not prevent the Executive from
earning a livelihood, (ii) that the Company and Bank do not have
an adequate remedy at law for a breach or threatened breach by
the Executive of the covenants in this Section and may obtain
injunctive and other equitable relief, in addition to receiving
its actual damages and any other remedies that may be available
to it hereunder or at law or by statute, (iii) that the covenants
herein contained are reasonable and necessary for the proper
protection of the Company, and (iv) that if any provision or part
of any such covenant is invalidated, the remainder shall
nevertheless continue to be valid and fully enforceable, and if a
court determines that the term of the covenant is too long or the
area covered thereby too great, so that the covenant as written
is unenforceable, the covenant shall be modified to encompass the
longest duration and largest geographic area that the court deems
enforceable under the law.

     11.  Successors.  (a)  This Agreement is personal to the
          -----------
Executive and without the prior written consent of the Company
shall not be assignable by the Executive otherwise than by will
or the laws of descent and distribution.  This Agreement shall
inure to the benefit of and be enforceable by the Executive's
legal representatives.

          (b)  This Agreement shall inure to the benefit of and
be binding upon the Company and its successors and assigns.

          (c)  The Company will require any successor (whether
direct or indirect, by purchase, merger, consolidation or
otherwise) to all or substantially all of the business and/or
assets of the Company to assume expressly and agree to perform
this Agreement in the same manner and to the same extent that the
Company would be required to perform it if no such succession had
taken place.  As used in this Agreement, "Company" shall mean the
Company as hereinbefore defined and any successor to its business
and/or assets as aforesaid which assumes and agrees to perform
this Agreement by operation of law, or otherwise.

     12.  Miscellaneous.  (a)  This Agreement shall be governed
          --------------
by and construed in accordance with the laws of the State of
Missouri, without reference to principles of conflict of laws.
The captions of this Agreement are not part of the provisions
hereof and shall have no force or effect. This Agreement may not
be amended or modified otherwise than by a written agreement
executed by the parties hereto or their respective successors and
legal representatives.

                      EMPLOYMENT AGREEMENT
                      --------------------


     AGREEMENT by and between Mercantile Bancorporation Inc., a
Missouri corporation (the "Company") and John P. Dubinsky (the
"Executive"), dated as of the 27th day of October, 1996.

     The Executive Committee of the Board of Directors of the
Company (the "Company Board") has determined that it is in the
best interests of the Company and its shareholders to assure that
the Company will have the dedication of the Executive pending the
merger of Mark Twain Bancshares, Inc. ("Mark Twain") and the
Company (the "Merger") pursuant to the Agreement and Plan of
Merger dated as of October 27, 1996, and to provide the surviving
corporation after the Merger with continuity of management.

     NOW, THEREFORE, IT IS HEREBY AGREED AS FOLLOWS:

     1.  Effective Date.  The "Effective Date" shall mean the
         ---------------
date on which the Effective Time of the Merger (as defined in the
Merger Agreement) occurs, provided that the Effective Time occurs
on or before December 31, 1997, or such later date as may be
mutually agreed upon by the Company and Mark Twain.

     2.  Employment Period.  The Company hereby agrees to
         ------------------
continue the Executive in its employ, and the Executive hereby
agrees to remain in the employ of the Company subject to the
terms and conditions of this Agreement, for the period commencing
on the Effective Date and ending on the second anniversary of
such date (the "Employment Period").

     3.  Terms of Employment.  (a)  Position and Duties.  (i)
         --------------------       --------------------
During the Employment Period, (A) the Executive shall serve as
President and Chief Executive Officer of the Company's St. Louis
banking affiliate ("Bank") and as a member of the Company's
Management Executive Committee and (B) the Executive's services
shall be performed in St. Louis, Missouri.

               (ii)  During the Employment Period, and excluding
any periods of vacation and sick leave to which the Executive is
entitled, the Executive agrees to devote reasonable attention and
time during normal business hours to the business and affairs of
Bank and to use the Executive's reasonable best efforts to
perform faithfully and efficiently such responsibilities.  The
Executive will be the officer responsible for retail and
commercial banking activities in the metropolitan St. Louis
market and shall report directly to the Chairman and Chief
Executive Officer of the Company.

          (b)  Compensation.  (i)  Base Salary.  During the
               -------------       ------------
Employment Period, the Executive shall receive an annual base
salary ("Annual Base Salary"), which shall be paid at an annual
rate of 105% of the Executive's annual base salary as of the date
hereof.  During the Employment Period, the Annual Base Salary
shall be reviewed annually in accordance with the Company's
customary practice and adjusted in accordance with the base salary


<PAGE> 3

adjustment, if any, of other peer executives of the Company.  Any increase in
Annual Base Salary shall not serve to limit or reduce any other obligation to
the Executive under this Agreement.  Annual Base Salary shall not be reduced
after any such increase and the term Annual Base Salary as utilized in this
Agreement shall refer to Annual Base Salary as so increased.  As
used in this Agreement, the term "affiliated companies" shall
include any company controlled by, controlling or under common
control with the Company.

               (ii)  Annual Bonus.  During the Employment Period,
                     -------------
in addition to Annual Base Salary, the Executive will be eligible
to receive, (I) for each fiscal year of the Company during which
the Executive is employed, an annual bonus (the "Annual Bonus")
in an amount to be determined by the Company Board of Directors,
but in no event shall the amount of the Annual Bonus during the
first fiscal year during which the Executive is employed (the
"First Fiscal Year") be less than the product of (x) .55 and (y)
the Annual Base Salary (the "Minimum Bonus") and (II) for that
portion of any fiscal year of the Company other than the First
Fiscal Year during which the Executive is employed for less than
twelve full months, an amount equal to the product of (x) the
greater of (A) the Minimum Bonus and (B) any other Annual Bonus
paid to the Executive during the Employment Period, and (y) a
fraction, the numerator of which is the number of days in such
fiscal year during which the Executive is employed by the
Company, and the denominator of which is 365.  Each such Annual
Bonus shall be paid in cash in a manner and at a time in
accordance with the Company's customary practices with respect to
other peer executives of the Company, but not later than January
31st of the year following the year to which such Annual Bonus
relates.

               (iii)  Incentive, Savings and Retirement Plans.
                      ----------------------------------------
During the Employment Period, the Executive shall be entitled to
participate in all incentive, savings and retirement plans,
practices, policies and programs applicable generally to other
peer executives of the Company and its affiliated companies.

               (iv)  Welfare Benefit Plans.  During the
                     ----------------------
Employment Period, the Executive and/or the Executive's family,
as the case may be, shall be eligible for participation in and
shall receive all benefits under welfare benefit plans,
practices, policies and programs provided by the Company and its
affiliated companies (including, without limitation, medical,
prescription, dental, disability, employee life, group life,
accidental death and travel accident insurance plans and
programs) to the extent applicable generally to other peer
executives of the Company and its affiliated companies.

               (v)  Expenses.  During the Employment Period, the
                    ---------
Executive shall be entitled to receive prompt reimbursement for
all reasonable expenses incurred by the Executive in accordance
with the Company's policies.

               (vi)  Fringe Benefits.  During the Employment
                     ----------------
Period, the Executive shall be entitled to fringe benefits on a
basis no less favorable than that applicable to other peer
executives of the Company and its affiliated companies, and also,
to the extent that the

                                    2
<PAGE> 4

Executive receives such fringe benefits as of the date hereof, payment of club
dues and use of an automobile and payment of related expenses.

               (vii)  Office and Support Staff.  During the
                      -------------------------
Employment Period, the Executive shall be entitled to an office
or offices of a size and with furnishings and other appointments,
and to personal secretarial and other assistance, as provided
generally to other peer executives of the Company and its
affiliated companies.

               (viii)  Vacation.  During the Employment Period,
                       ---------
the Executive shall be entitled to paid vacation in accordance
with the plans, policies, programs and practices of the Company
and its affiliated companies on the basis no less favorable than
that applicable to other peer executives of the Company and its
affiliated companies.

     4.  Termination of Employment.  (a)  Death or Disability.
         --------------------------       --------------------
The Executive's employment shall terminate automatically upon the
Executive's death during the Employment Period.  If the Company
determines in good faith that the Disability of the Executive has
occurred during the Employment Period (pursuant to the definition
of Disability set forth below), it may give to the Executive
written notice in accordance with Section 12(b) of this Agreement
of its intention to terminate the Executive's employment.  In
such event, the Executive's employment with the Company shall
terminate effective on the 30th day after receipt of such notice
by the Executive (the "Disability Effective Date"), provided
that, within the 30 days after such receipt, the Executive shall
not have returned to full-time performance of the Executive's
duties.  For purposes of this Agreement, "Disability" shall mean
the absence of the Executive from the Executive's duties with the
Company or Bank on a full-time basis for 180 consecutive business
days as a result of incapacity due to mental or physical illness
which is determined to be total and permanent by a physician
selected by the Company or its insurers and acceptable to the
Executive or the Executive's legal representative.

          (b)  Cause.  The Company or Bank may terminate the
               ------
Executive's employment during the Employment Period for Cause.
For purposes of this Agreement, "Cause" shall mean:

               (i)  The Executive's willful and continued failure
to substantially perform his duties (other than as a result of
incapacity due to physical or mental condition), after a written
demand for performance is delivered to the Executive which
specifically identifies the manner in which the Executive has not
substantially performed his duties; or

               (ii)  The Executive's willful commission or
misconduct which is materially injurious to the Company and/or
Bank, monetarily or otherwise; or

               (iii)  Conviction of the Executive of a felony; or

                                    3
<PAGE> 5

               (iv)  A determination by the Company or Bank that
the Executive has committed fraud, embezzlement, theft, or
misappropriation against or from the Company or Bank; or

               (v)  The Executive's material breach of any
provision of this Agreement, including any breach of Section 10.

For purposes of this Section, no act or failure to act shall be
considered "willful" unless done or omitted to be done without
good faith and without a reasonable belief that the act or
omission was in the best interest of the Company and/or Bank.

          (c)  Good Reason.  The Executive's employment may be
               ------------
terminated by the Executive for Good Reason.  For purposes of
this Agreement, "Good Reason" shall mean a termination by the
Executive following a material breach of this Agreement by the
Company that is not cured after reasonable notice of such breach.
Anything in this Agreement to the contrary notwithstanding, a
termination by the Executive of his employment for any reason or
no reason during the 30-day period immediately following the
thirteenth (13th) month anniversary of the Effective Date shall
be deemed to be a termination for Good Reason for all purposes of
this Agreement.

          (d)  Notice of Termination.  Any termination by the
               ----------------------
Company or Bank for Cause, or by the Executive for Good Reason,
shall be communicated by Notice of Termination to the other party
hereto given in accordance with Section 12(b) of this Agreement.
For purposes of this Agreement, a "Notice of Termination" means a
written notice which (i) indicates the specific termination
provision in this Agreement relied upon, (ii) to the extent
applicable, sets forth in reasonable detail the facts and
circumstances claimed to provide a basis for termination of the
Executive's employment under the provision so indicated and (iii)
if the Date of Termination (as defined below) is other than the
date of receipt of such notice, specifies the termination date
(which date shall be not more than thirty days after the giving
of such notice).  The failure by the Executive, the Company or
Bank to set forth in the Notice of Termination any fact or
circumstance which contributes to a showing of Good Reason or
Cause shall not waive any right of the Executive, the Company or
Bank, respectively, hereunder or preclude the Executive, the
Company or Bank, respectively, from asserting such fact or
circumstance in enforcing the Executive's, the Company's or
Bank's rights hereunder.

          (e)  Date of Termination.  "Date of Termination" means
               --------------------
(i) if the Executive's employment is terminated by the Company or
Bank for Cause, or by the Executive for Good Reason, the date of
receipt of the Notice of Termination or any later date specified
therein, as the case may be, (ii) if the Executive's employment
is terminated by the Company or Bank other than for Cause or
Disability, the Date of Termination shall be the date on which
the Company or Bank notifies the Executive of such termination
and (iii) if the Executive's employment is terminated by reason
of death or Disability, the Date of Termination shall be the date
of death of the Executive or the Disability Effective Date, as
the case may be.

                                    4
<PAGE> 6

     5.  Obligations of the Company upon Termination.  (a) Good
         --------------------------------------------      ----
Reason; Other Than for Cause, Death or Disability.  If, during
- --------------------------------------------------
the Employment Period, (I) the Company or Bank shall terminate
the Executive's employment other than for Cause, Death or
Disability or (II) the Executive shall terminate employment for
Good Reason:

               (i)  the Company shall pay to the Executive the
aggregate of the following amounts:

               A.  The Executive's Annual Base Salary through the
Date of Termination to the extent not theretofore paid ("Accrued
Salary"), provided that if the employment of the Executive is
terminated without Cause or for Good Reason before the fourteenth
(14th) month anniversary date of the Effective Date, the Date of
Termination shall be deemed to be said fourteenth (14th) month
anniversary date and the Accrued Bonus (as defined in paragraph
5(b)) shall be added to and be deemed a part of the Annual Base
Salary; and

               B.  $1.2 million, payable in 24 equal monthly
installments (the "Termination Payment") (which is approximately
the amount that would be owed to the Executive as a termination
payment under the existing employment arrangements with Mark
Twain).

               (ii)  For the greater of (1) twelve months or (2)
the number of months remaining in the Employment Period on the
Date of Termination, or such longer period as may be provided by
the terms of the appropriate plan, program, practice or policy
(the "Benefit Continuation Period"), the Company shall after the
Executive's Date of Termination continue benefits to the
Executive and/or the Executive's family at least equal to those
which would have been provided to them in accordance with the
plans, programs, practices and policies described in Section
3(b)(iv) of this Agreement if the Executive's employment had not
been terminated or, if more favorable to the Executive, as in
effect generally at any time thereafter with respect to other
peer executives of the Company and its affiliated companies and
their families, provided, however, that if the Executive becomes
reemployed with another employer and is eligible to receive
medical or other welfare benefits under another employer provided
plan, the medical and other welfare benefits described herein
shall be secondary to those provided under such other plan during
such applicable period of eligibility. For purposes of
determining eligibility (but not the time of commencement of
benefits) of the Executive for retiree benefits pursuant to such
plans, practices, programs and policies, the Executive shall be
considered to have remained employed during the Benefit
Continuation Period and to have retired an the last day of such
period;

               (iii)  To the extent not theretofore paid or
provided, the Company shall timely pay or provide to the
Executive any other amounts or benefits required to be paid or
provided or which the Executive is eligible to receive under any
plan, program, policy or practice or contract or agreement of the
Company and its affiliated companies (such other amounts and
benefits shall be hereinafter referred to as the "Other
Benefits").

                                    5
<PAGE> 7

          (b)  Death.  If the Executive's employment is
               ------
terminated by reason of the Executive's death during the
Employment Period, this Agreement shall terminate without further
obligations to the Executive's legal representatives under this
Agreement, other than for payment of Accrued Salary and the
Termination Payment (if not previously paid), an amount equal to
the product of (x) the Annual Bonus paid or payable, including
any bonus or portion thereof which has been earned but deferred
(and annualized for any fiscal year of the Company consisting of
less than twelve full months or during which the Executive was
employed for less than twelve full months), for the most recently
completed fiscal year during the Employment Period, if any, or,
in the event that a fiscal year of the Company has not been
completed during the Employment Period as of the Date of
Termination, the Minimum Bonus, and (y) a fraction, the numerator
of which is the number of days in the current fiscal year of the
Company through the Date of Termination, and the denominator, of
which is 365 (the "Accrued Bonus") and the timely payment or
provision of Other Benefits.  The Accrued Salary, the Termination
Payment and Accrued Bonus shall be paid to the Executive's estate
or beneficiary, as applicable, in a lump sum in cash within 30
days of the Date of Termination.  With respect to the provision
of Other Benefits, the term Other Benefits as utilized in this
Section 5(b) shall include, without limitation, and the
Executive's estate and/or beneficiaries shall be entitled to
receive, benefits at least equal to the most favorable benefits
provided by the Company and affiliated companies to the estates
and beneficiaries of peer executives of the Company and such
affiliated companies under such plans, programs, practices and
policies relating to death benefits, if any, as in effect with
respect to other peer executives and their beneficiaries at any
time during the 120-day period immediately preceding the
Effective Date or, if more favorable to the Executive's estate
and/or the Executive's beneficiaries, as in effect on the date of
the Executive's death with respect to other peer executives of
the Company and its affiliated companies and their beneficiaries.

          (c)  Disability.  If the Executive's employment is
               -----------
terminated by reason of the Executive's Disability during the
Employment Period, this Agreement shall terminate without further
obligations to the Executive, other than for payment of Accrued
Salary, the Termination Payment (if not previously paid), Accrued
Bonus, and the timely payment or provision of Other Benefits. The
Accrued Salary, the Termination Payment and the Accrued Bonus
shall be paid to the Executive in a lump sum in cash within 30
days of the Date of Termination. With respect to the provision of
Other Benefits, the term Other Benefits as utilized in this
Section 5(c) shall include, and the Executive shall be entitled
after the Disability Effective Date to receive, disability and
other benefits in accordance with such plans, programs, practices
and policies relating to disability, if any, as in effect
generally with respect to other peer executives of the Company
and its affiliated companies and their families.

          (d)  Cause; Other than for Good Reason.  If the
               ----------------------------------
Executive's employment shall be terminated for Cause or by the
Executive other than for Good Reason during the Employment
Period, this Agreement shall terminate without further
obligations to the

                                    6
<PAGE> 8

Executive other than the obligation to pay to the Executive his Accrued Salary
and Other Benefits, in each case to the extent theretofore unpaid.

     6.  Non-exclusivity of Rights.  Nothing in this Agreement
         --------------------------
shall prevent or limit the Executive's continuing or future
participation in any plan, program, policy or practice provided
by the Company or any of its affiliated companies and for which
the Executive may qualify, nor shall anything herein limit or
otherwise affect such rights as the Executive may have under any
contract or agreement with the Company or any of its affiliated
companies.  Amounts which are vested benefits or which the
Executive is otherwise entitled to receive under any plan,
policy, practice or program of or any contract or agreement with
the Company or any of its affiliated companies at or subsequent
to the Date of Termination shall be payable in accordance with
such plan, policy, practice or program or contract or agreement
except as explicitly modified by this Agreement.

     7.  Full Settlement.  The Company's obligation to make the
         ----------------
payments provided for in this Agreement and otherwise to perform
its obligations hereunder shall not be affected by any set-off,
counterclaim, recoupment, defense or other claim, right or action
which the Company may have against the Executive or others.  In
no event shall the Executive be obligated to seek other
employment or take any other action by way of mitigation of the
amounts payable to the Executive under any of the provisions of
this Agreement and such amounts shall not be reduced whether or
not the Executive obtains other employment.  The Company agrees
to pay as incurred, to the full extent permitted by law, all
legal fees and expenses which the Executive may reasonably incur
as a result of any contest (regardless of the outcome thereof) by
the Company, the Executive or others of the validity or
enforceability of, or liability under, any provision of this
Agreement or any guarantee of performance thereof (including as a
result of any contest by the Executive about the amount of any
payment pursuant to this Agreement), plus in each case interest
on any delayed payment at the applicable Federal rate provided
for in Section 7872(f)(2)(A) of the Internal Revenue Code of
1986, as amended (the "Code").

     8.  Certain Reduction of Payments by the Company.  (a)  For
         ---------------------------------------------
purposes of this Section 8, (i) a "Payment" shall mean any
payment or distribution in the nature of compensation to or for
the benefit of the Executive, whether paid or payable pursuant to
this Agreement or otherwise; (ii) "Separation Payment" shall mean
a Payment paid or payable pursuant to this Agreement
(disregarding this Section); (iii) "Net After Tax Receipt" shall
mean the Present Value of a Payment net of all taxes imposed on
the Executive with respect thereto under Sections 1 and 4999 of
the Internal Revenue Code of 1986, as amended (the "Code"),
determined by applying the highest marginal rate under Section 1
of the Code which applied to the Executive's taxable income for
the immediately preceding taxable year; (iv) "Present Value"
shall mean such value determined in accordance with Section
280G(d)(4) of the Code; and (v) "Reduced Amount" shall mean the
greatest aggregate amount of Separation Payments which (a) is
less than the sum of all Separation Payments and (b) results in
aggregate Net After Tax Receipts which are equal to or greater
than the Net After Tax Receipts which would result if the
Executive were paid the sum of all Separation Payments.

                                    7
<PAGE> 9

          (b)  Anything in this Agreement to the contrary
notwithstanding, in the event KPMG Peat Marwick LLP or such other
nationally recognized certified public accounting firm designated
by the Executive (the "Accounting Firm") shall determine that
receipt of all Payments would subject the Executive to tax under
Section 4999 of the Code, it shall determine whether some amount
of Separation Payments would meet the definition of a "Reduced
Amount."  If the Accounting Firm determines that there is a
Reduced Amount, the aggregate Separation Payments shall be
reduced to such Reduced Amount. All fees payable to the
Accounting Firm shall be paid solely by the Company.

          (c)  If the Accounting Firm determines that aggregate
Separation Payments should be reduced to the Reduced Amount, the
Company shall promptly give the Executive notice to that effect
and a copy of the detailed calculation thereof, and the Executive
may then elect, in his sole discretion, which and how much of the
Separation Payments shall be eliminated or reduced (as long as
after such election the present value of the aggregate Separation
Payments equals the Reduced Amount), and shall advise the Company
in writing of his election within ten days of his receipt of
notice.  If no such election is made by the Executive within such
ten-day period, the Company may elect which of such Separation
Payments shall be eliminated or reduced (as long as after such
election the present value of the aggregate Separation Payments
equals the Reduced Amount) and shall notify the Executive
promptly of such election.  All determinations made by the
Accounting Firm under this Section shall be binding upon the
Company and the Executive and shall be made within 60 days of a
termination of employment of the Executive.  As promptly as
practicable following such determination, the Company shall pay
to or distribute for the benefit of the Executive such Separation
Payments as are then due to the Executive under this Agreement
and shall promptly pay to or distribute for the benefit of the
Executive in the future such Separation Payments as become due to
the Executive under this Agreement.

          (d)  While it is the intention of the Company to reduce
the amounts payable or distributable to the Executive hereunder
only if the aggregate Net After Tax Receipts to an Executive
would thereby be increased, as a result of the uncertainty in the
application of Section 4999 of the Code at the time of the
initial determination by the Accounting Firm hereunder, it is
possible that amounts will have been paid or distributed by the
Company to or for the benefit of the Executive pursuant to this
Agreement which should not have been so paid or distributed
("Overpayment") or that additional amounts which will have not
been paid or distributed by the Company to or for the benefit of
the Executive pursuant to this Agreement could have been so paid
or distributed ("Underpayment"), in each case, consistent with
the calculation of the Reduced Amount hereunder.  In the event
that the Accounting Firm, based upon the assertion of a
deficiency by the Internal Revenue Service against the Company or
the Executive which deficiency the Accounting Firm believes has a
high probability of success, determines that an Overpayment has
been made, any such Overpayment paid or distributed by the
Company to or for the benefit of the Executive shall be treated
for all purposes as a loan to the Executive which the Executive
shall repay to the Company together with interest at the
applicable federal rate provided for in Section 7872(f)(2) of the
Code; provided, however, that no such loan shall be deemed to
have been

                                    8
<PAGE> 10

made and no amount shall be payable by the Executive to the
Company if and to the extent such deemed loan and payment
would not either reduce the amount on which the Executive is
subject to tax under Section 1 and Section 4999 of the Code or
generate a refund of such taxes.  In the event that the
Accounting Firm, based upon controlling precedent or substantial
authority, determines that an Underpayment has occurred, any such
Underpayment shall be promptly paid by the Company to or for the
benefit of the Executive together with interest at the applicable
federal rate provided for in Section 7872(f)(2) of the Code.

     9.  Confidential Information.  The Executive shall hold in a
         -------------------------
fiduciary capacity for the benefit of the Company and Bank all
secret or confidential information, knowledge or data relating to
the Company or Bank or any of their affiliated companies, and
their respective businesses, which shall have been obtained by
the Executive during the Executive's employment by the Company or
any of its affiliated companies and which shall not be or become
public knowledge (other than by acts by the Executive or
representatives of the Executive in violation of this Agreement).
After termination of the Executive's employment, the Executive
shall not, without the prior written consent of the company or as
may otherwise be required by law or legal process, communicate or
divulge any such information, knowledge or data to anyone other
than the Company and those designated by it.  In no event shall
an asserted violation of the provisions of this Section 9
constitute a basis for deferring or withholding any amounts
otherwise payable to the Executive under this Agreement.

     10.  Covenant Not To Engage in Competitive or Other
          ----------------------------------------------
Detrimental Activities.  (a)  The Executive covenants that from
- -----------------------
and after the Effective Date he will not compete with the
Company, Bank and/or their affiliates and further covenants that
he will not take any action which is detrimental to the Company,
Bank and/or their affiliates (i) during the Employment Period,
and (ii) if the Executive's employment terminates for any reason
(other than the Executive's death) or no reason during the
Employment Period, for an additional three (3) year period of
time beginning on the Date of Termination.

          (b)  For purposes of paragraph (a) of this Section 10,
the Executive shall be deemed to be competing with the Company,
Bank and/or their affiliates at any time if the Executive accepts
employment with, or serves as an agent, employee, or director of,
or a consultant to, a competitor of the Company, Bank and/or
their affiliates, or during such time the Executive acquires or
has an interest (direct or indirect) in any firm, corporation or
enterprise engaged in a business which is in competition with the
Company, Bank and/or their affiliates, or at any time, either
during employment or thereafter, the Executive divulges any
information concerning the Company, Bank and/or their affiliates
which is or could be of aid to any such competitor.  The mere
ownership of a less than a 3% debt and/or equity interest in a
competing company whose stock is publicly held shall not be
considered as having the prohibited interest in a competitor, and
neither shall the mere ownership of a less than a 10% debt and/or
equity interest in a competing company whose stock is not
publicly held.  For purposes of this Agreement, any commercial
bank, savings and loan association, securities broker or dealer,
or other business or financial institution that is principally
engaged in the business of offering any service at the time
offered by the Company, Bank

                                    9
<PAGE> 11

and/or their affiliates, and which conducts business in any location
encompassed within the areas circumscribed by circles, of which the radii are
50 miles and the mid-points are the geographic centers of Kansas City,
Missouri, and St. Louis, Missouri, shall be deemed to be a competitor.

          (c)  Should the Company reasonably and in good faith
believe that the Executive has violated any of the foregoing
provisions, it shall give the Executive written notice to such
effect, stating the reason(s) for its belief, and pending a final
determination as to whether there has been a violation may,
without penalty or risk of claim for actual or punitive damages,
suspend payment of any further amount which might otherwise
become payable hereunder after thirty (30) days of giving such
notice.  The Company shall, in an expeditious manner, determine
from all information available to it whether the Executive
violated any of the foregoing covenants, and if the Company in
good faith concludes that the Executive has violated this
Agreement, the Executive shall not be entitled to any further
payment hereunder.

          (d)  The Executive represents, acknowledges and agrees
(i) that his experience and capabilities are such that he can
obtain employment in activities which do not violate such
agreement and that the enforcement by way of injunction of the
agreement not to compete will not prevent the Executive from
earning a livelihood, (ii) that the Company and Bank do not have
an adequate remedy at law for a breach or threatened breach by
the Executive of the covenants in this Section and may obtain
injunctive and other equitable relief, in addition to receiving
its actual damages and any other remedies that may be available
to it hereunder or at law or by statute, (iii) that the covenants
herein contained are reasonable and necessary for the proper
protection of the Company, and (iv) that if any provision or part
of any such covenant is invalidated, the remainder shall
nevertheless continue to be valid and fully enforceable, and if a
court determines that the term of the covenant is too long or the
area covered thereby too great, so that the covenant as written
is unenforceable, the covenant shall be modified to encompass the
longest duration and largest geographic area that the court deems
enforceable under the law.

     11.  Successors.  (a) This Agreement is personal to the
          -----------
Executive and without the prior written consent of the Company
shall not be assignable by the Executive otherwise than by will
or the laws of descent and distribution.  This Agreement shall
inure to the benefit of and be enforceable by the Executive's
legal representatives.

          (b)  This Agreement shall inure to the benefit of and
be binding upon the Company and its successors and assigns.

          (c)  The Company will require any successor (whether
direct or indirect, by purchase, merger, consolidation or
otherwise) to all or substantially all of the business and/or
assets of the Company to assume expressly and agree to perform
this Agreement in the same manner and to the same extent that the
Company would be required to perform it if no such succession had
taken place.  As used in this Agreement, "Company" shall mean the

                                    10
<PAGE> 12

Company as hereinbefore defined and any successor to its business
and/or assets as aforesaid which assumes and agrees to perform
this Agreement by operation of law, or otherwise.

     12.  Miscellaneous.  (a) This Agreement shall be governed by
          --------------
and construed in accordance with the laws of the State of
Missouri, without reference to principles of conflict of laws.
The captions of this Agreement are not part of the provisions
hereof and shall have no force or effect. This Agreement may not
be amended or modified otherwise than by a written agreement

          (e)  The Executive's or the Company's failure to insist
upon strict compliance with any provision of this Agreement or
the failure to assert any right the Executive or the Company may
have hereunder shall not be deemed to be a waiver of such
provision or right or any other provision or right of this
Agreement.

                                    11
<PAGE> 13
