ALLEGIANT BANCORP, INC.
FORM 10-Q/A

         Explanatory Note: This Form 10-Q/A presents restated quarterly
         ----------------
condensed consolidated financial statements as of June 30, 2002 and for the
quarter and six months then ended, for Allegiant Bancorp, Inc.
("Allegiant").

         In the third quarter of 2002, Allegiant adopted SFAS 147,
Acquisition of Certain Financial Institutions. As permitted by the new
accounting standard issued on October 1, 2002, we reclassified previously
recorded intangible assets associated with branch acquisitions to goodwill.
As required by SFAS 147, we restated previously reported 2002 six-month
earnings to reflect the non-amortization of goodwill related to our branch
acquisitions. For the three months and six months ended June 30, 2002 the
impact related to the implementation of SFAS 147 was to increase net income
by $172,000 and $345,000, and increase diluted earnings per share by $0.01
and $0.02 per share.

         At the same time, we also restated previously reported 2002
six-month earnings to recognize the impact of a $700,000 deferred loan fee
which had not been accreted into income due to an accounting oversight
during the three months ended March 31, 2002 and June 30, 2002 in accordance
with SFAS 91, Accounting for Non-refundable Fees and Costs Associated with
Originating or Acquiring Loans and Initial Direct Costs of Leases. For the
three and six months ended June 30, 2002, the impact for the loan fee
correction was to increase net income by $146,000 and $291,000, and diluted
earnings per share by $0.01 and $0.02 per share.

         The matters relating to the restatement have a financial statement
impact for the periods covered by this 10-Q/A as follows:

ALLEGIANT BANCORP, INC.
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)(AS RESTATED)


Basis of Presentation

         The accompanying condensed consolidated financial statements
include the accounts of Allegiant Bancorp, Inc. and its subsidiaries. The
terms "Allegiant," "company," "we," "our," and "corporation" as used in this
report refer to Allegiant Bancorp, Inc. and its subsidiaries as a
consolidated entity, except where we clearly indicate that it means only
Allegiant Bancorp, Inc. Also, sometimes we refer to Allegiant Bank, Bank of
Ste. Genevieve and State Bank of Jefferson County, our bank subsidiaries, as
the "banks."

         The accompanying unaudited condensed consolidated financial
statements have been prepared in accordance with generally accepted
accounting principles for interim financial information and with the
instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly,
they do not include all of the information and footnotes required by
generally accepted accounting principles for complete financial statements.
In the opinion of management, all adjustments (consisting of normal
recurring accruals) considered necessary for a fair presentation have been
included. Operating results for the three-month and six-month period ended
June 30, 2002 are not necessarily indicative of the results that may be
expected for the year ending December 31, 2002.

         The balance sheet at December 31, 2001 has been derived from the
audited financial statements at that date but does not include all of the
information and footnotes required by generally accepted accounting
principles for complete financial statements.

         For further information, refer to the consolidated financial
statements and footnotes thereto included in our Annual Report on Form 10-K
for the year ended December 31, 2001.

Comprehensive Income


         During the second quarter of 2002 and 2001, total comprehensive
income amounted to $9.5 million and $2.8 million, respectively. Year-to-date
comprehensive income for the first half of 2002 and 2001 was $14.1 million
and $6.7 million, respectively.


Acquisitions

         On September 28, 2001, we acquired Southside Bancshares Corp.
("Southside"). Before the acquisition, Southside was a bank holding company
with four subsidiary banks in and around St. Louis, Missouri, which at
closing reported consolidated total assets of approximately $804.9 million.
Under the terms of the agreement, one-half of the Southside shares were
converted into the right to receive cash in the amount of $14 per share and
the other half into the right to receive 1.39 shares of Allegiant stock per
share. Under the terms of the agreement, we exchanged a total of
approximately 5.9 million shares of Allegiant common stock plus $59 million
in cash for all of the outstanding common stock of Southside. The issuance
of Allegiant shares and cash to the former Southside shareholders was
completed on November 2, 2001. We financed the cash portion of the purchase
price through the issuance of trust preferred securities and bank
borrowings. We accounted for the acquisition under the purchase method and
recorded goodwill and a core deposit intangible of $33.6 million and $11.0
million, respectively. The core deposit intangible is being amortized over
an estimated


                                     5

<PAGE>
<PAGE>

useful life of ten years and none of this amortization is expected to be
deductible for tax purposes. During October 2001 and May 2002, respectively,
we merged Southside National Bank and the Bank of St. Charles County, two of
the four subsidiary banks acquired from Southside, into Allegiant Bank.


         On December 12, 2001, we acquired five St. Louis County branches
from Guardian Savings Bank ("Guardian") which is headquartered in Houston,
Texas. In addition to the branch facilities, we assumed $109.3 million in
related deposit liabilities. As a result of the Guardian branch acquisition,
we recorded $2.2 million of goodwill. We believe the acquisitions of Southside
and the Guardian branches significantly enhanced the scale of our banking
business and positioned us for further growth and to compete effectively by
offering personalized banking products and services in the St. Louis
community.


Subsequent Event

         On July 31, 2002, we announced the signing of a definitive
agreement to acquire Investment Counselors, Incorporated (Investment
Counselors), a privately held investment advisory firm located in St. Louis,
Missouri. Under terms of the agreement, the total consideration to be
received by Investment Counselors' shareholders will be shares of Allegiant
Bancorp common stock. This acquisition is consistent with our strategy of
focusing on the growth of non-interest income. Investment Counselors has
been serving institutional and high net worth individuals in the Midwest
since 1968. Upon completion of this transaction, which is expected to be
completed in the fourth quarter of 2002, our Wealth Management division will
have Trust and Investment Advisory assets in excess of $800 million.

Recently Issued Accounting Standards

         Effective January 1, 2002, the Company adopted Financial Accounting
Standards Board issued Statement of Financial Accounting Standards (SFAS)
No. 142, Goodwill and Other Intangible Assets. In accordance with this
statement, goodwill and intangible assets deemed to have indefinite lives
will no longer be amortized but will be subject to impairment tests in
accordance with the Statement. Other intangible assets will continue to be
amortized over their estimated useful lives. During 2002, the Company is
performing the first of the required impairment tests of goodwill and
indefinite lived intangible assets as of January 1, 2002 and has not yet
determined what the effect of those tests will be on the future consolidated
earnings and financial position of the Company. If for any future period we
determine that there has been impairment in the carrying value of our
goodwill balances, we will record a charge to our earnings, which could have
a material adverse effect on our net income.

Restatement

         Allegiant's financial statements as of June 30, 2002 and for the
three-month and six-month periods then ended, have been restated. The
restatement reflects an increase in interest income and a decrease in
amortization expense, a component of other expenses. Prior to the issuance
of Allegiant's financial statements as of September 30, 2002 and for the
three- and nine-month periods then ended, Allegiant restated the financial
statements included in the Forms 10-Q for the quarters ended March 31, 2002
and June 30, 2002, as originally filed. The changes to the financial
statements resulting from the restatement are described below.

         Interest Income and Loans. In the third quarter of 2002, Allegiant
recognized a $700,000 loan fee which had not been accreted into income due
to an accounting oversight during the three months ended March 31, 2002 and
June 30, 2002 in accordance with SFAS 91. As a result, previously recorded
interest income was understated by $235,000 for the three-month period ended
June 30, 2002 and $469,000 for the six-month period 2002. Loans, at June 30,
2002, decreased by $231,000.

         Amortization Expense and Goodwill. In the third quarter of 2002,
Allegiant adopted SFAS 147, Acquisition of Certain Financial Institutions.
As permitted by the new accounting standard issued on October 1, 2002,
Allegiant reclassified previously recorded intangible assets associated with
branch acquisitions to goodwill. As required by SFAS 147, previously
reported amortization expense was decreased by $172,000 for the three-month
period ended June 30, 2002 and $345,000 for the six-month period ended June
30, 2002. Goodwill (cost in excess of fair value of net assets acquired) was
increased by $345,000 at June 30, 2002.

         As a result, the financial statements as of June 30, 2002 and for
the three-month and six-month periods then ended and related disclosures
included in this quarterly report, have been restated to reflect the
restatement of interest income and amortization expense. The effect of
restatement on the quarter and six-month periods ended June 30, 2002, is
shown in the table below:

ITEM 2.    MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS (AS RESTATED)


         This report contains certain forward-looking statements with
respect to the financial condition, results of operations and business of
Allegiant and our subsidiaries. These forward-looking statements involve
certain risks and uncertainties. For example, by accepting deposits at fixed
rates, at different times and for different terms, and lending funds at
fixed rates for fixed periods, we accept the risk that the cost of funds may
rise and interest on loans and investment securities may be at a fixed rate.
Similarly, the cost of funds may fall, but we may have committed by virtue
of the term of a deposit to pay what becomes an above-market rate.
Investments may decline in value in a rising interest rate environment.
Loans have the risk that the borrower will not repay all funds in a timely
manner, as well as the risk of total loss. Collateral may or may not have
the value attributed to it. The loan loss reserve, while believed adequate,
may prove inadequate if one or more large borrowers, or numerous smaller
borrowers, or a combination of both, experience financial difficulty for
individual, national or international reasons. Because the business of
banking is highly regulated, decisions of governmental authorities, such as
the rate of deposit insurance, can have a major effect on operating results.
All of these uncertainties, as well as others, are present in a banking
operation and we caution shareholders that management's view of the future
on which it prices our products, evaluates collateral, sets loan loss
reserves and estimates costs of operation and regulation may prove to be
other than anticipated.

         The profitability of our operations depends on our net interest
income, provision for loan losses, non-interest income and non-interest
expense. Net interest income is the difference between the income we receive
on our loan and investment portfolios and our cost of funds, which consists
of interest paid on deposits and borrowings. The provision for loan losses
reflects the cost of credit risk in our loan portfolio. Non-interest income
consists primarily of service charges on deposit accounts and fees for
ancillary banking services and, to a lesser extent, revenues generated from
our mortgage banking, securities brokerage, insurance brokerage and trust
operations. Non-interest expense includes salaries and employee benefits, as
well as occupancy, data processing, marketing, professional fees, insurance
and other expenses. Under recently adopted accounting rules, we will be
required to periodically evaluate the carrying values of our goodwill
balances to determine whether the values have been impaired. If we determine
that there has been an impairment, we will recognize a charge to our
earnings, which could be material.

         Our net interest income depends on the amounts and yields of
interest-earning assets compared to the amounts and rates on
interest-bearing liabilities. Net interest income is sensitive to changes in
market rates of interest and our asset/liability management procedures in
managing those changes. The provision for loan losses is dependent on
increases in the loan portfolio, management's assessment of the
collectibility of the loan portfolio and loss experience, as well as
economic and market factors.

OVERVIEW


         We are a bank holding company headquartered in St. Louis, Missouri.
Our bank subsidiaries, Allegiant Bank, Bank of Ste. Genevieve and State Bank
of Jefferson County, offer full-service banking and personal trust services
to individuals, commercial business and municipalities in the St. Louis
metropolitan area. Our services include commercial, real estate and
installment loans, checking, savings and time deposit accounts, personal
trust and other fiduciary services and other financial services such as
securities brokerage, insurance and safe

                                     9

deposit boxes. As of June 30, 2002, we reported, on a consolidated basis,
total assets of $2.2 billion, loans of $1.5 billion, deposits of $1.6
billion and shareholders' equity of $154.3 million.

         Since our inception in 1989, we have grown through a combination of
internal growth and acquisitions of other financial institutions. Our
internal growth has been achieved by positioning Allegiant as one of the
leading St. Louis community banking operations. We have supplemented our
growth by acquiring 31 branch locations in our community from four different
thrifts and another banking organization. Our primary goals have been to
expand our branch network in the St. Louis market while increasing our
earnings per share. We have also acquired a mortgage company and an asset
management firm. In December 1998, we sold four branches located in more
rural markets in northeast Missouri, in order to focus our operations
exclusively in the St. Louis metropolitan area. In November 2000, we
acquired Equality Bancorp, Inc. a community-based thrift holding company
with seven branches in the St. Louis area and total assets of approximately
$300.4 million. As a continuation of our acquisition and growth strategies,
in September 2001, we acquired Southside Bancshares Corp., another
community-based bank holding company serving the St. Louis area, with total
assets of approximately $804.9 million. In addition, in December 2001, we
acquired five St. Louis branch facilities from Guardian Savings Bank and
assumed approximately $109.3 million in related deposit liabilities.


         Since the beginning of 1998, we have focused on improving the
profitability of our banking operations. As a result, we have reduced the
amount of one- to four-family mortgages we hold in our loan portfolio and
have increased our amount of higher yielding commercial loans. We have hired
more than 20 banking professionals averaging more than 10 years of
experience in the St. Louis metropolitan area to help grow our commercial
loans and deposits. We have also implemented company-wide cost-control
efforts to enhance efficiencies throughout our operations. These steps taken
since the beginning of 1998 have improved our efficiency, return on average
assets, return of average equity and earnings per share.

         Our primary financial objectives are to continue to grow our loan
portfolio while maintaining high asset quality, expand our core deposit base
to provide a cost-effective and stable source of funding our loan portfolio
and increase non-interest income while maintaining strong expense controls.
We have sought to maintain high asset quality while managing growth both
internally and by acquisition.

RESULTS OF OPERATIONS


         Net income for the three months ended June 30, 2002 was $5.40
million, a 93% increase over the $2.80 million earned in the second quarter
of 2001. Basic earnings per share were $0.34 for the second quarter of 2002
compared to $0.31 for the second quarter of 2001. Diluted earnings per share
increased 9.7% to $0.34 for the second quarter of 2002 compared to $0.31 for
the second quarter of 2001. The annualized return on average assets for the
second quarter of 2002 was 0.99%, compared to the 0.98% annualized return on
average assets reported for the second quarter of 2001. The return on
average equity on an annualized basis was 14.50% for the second quarter of
2002 compared to 13.58% for the second quarter of 2001.

         Net income for the six-month period ended June 30, 2002 was $10.35
million, a 93% increase over the $5.37 million earned in the six-month
period ended June 30, 2001. Basic earnings per share were $0.67 and $0.60,
respectively, for the six-month periods ended June 30, 2002 and 2001.
Diluted earnings per share were $0.65 and $0.60, respectively, for the
six-


                                    10

<PAGE>

month periods ended June 30, 2002 and 2001. The annualized return on
average assets for the first six months of 2002 was 0.95%, compared to the
0.94% annualized return on average assets reported for the first six months
of 2001. The return on average equity on an annualized basis was 14.23% for
the first six months of 2002 compared to 13.18% for the first six months of
2001.

         As a result of newly effective accounting pronouncements, we have
discontinued the amortization of goodwill in 2002 and will periodically
determine whether the carrying value of our goodwill is impaired. As
required by these pronouncements, we continue to amortize core deposit
premiums and other identifiable intangibles as a noncash charge that
increases our operating expenses. Intangible asset amortization included as
an operating expense totaled $271,000 and $238,000 for the three-month
periods ended June 30, 2002 and 2001, respectively. Intangible asset
amortization included as an operating expense totaled $541,000 and $474,000
for the six-month periods ended June 30, 2002 and 2001, respectively.


         Total assets at June 30, 2002 were $2.2 billion and reflected a 92%
increase from June 30, 2001. Total loans increased to $1.5 billion and total
deposits increased to $1.6 billion at June 30, 2002.


         Net Interest Income. Net interest income for the three months ended
June 30, 2002 was $16.30 million, an 87% increase compared to the $8.73
million reported for the second quarter of 2001. This $7.58 million increase
was attributable to an increase of $929 million in average earning assets
primarily from our September 2001 acquisition of Southside Bancshares Corp.
The $9.35 million increase in interest income was partially offset by a
$1.78 million increase in interest expense. The increase in interest expense
was the result of an $888 million increase in average interest-bearing
liabilities partially offset by a decrease of 215 basis points in the
average interest rate paid between the periods.

         Net interest margin for the second quarter of 2002 decreased 1
basis point compared to the second quarter of 2001. The earning assets
yield decreased 190 basis points while the overall interest rate paid on
interest-bearing liabilities decreased 215 basis points. The net interest
spread increased 25 basis points comparing the second quarter 2002 to the
second quarter 2001.


         Interest expense on deposits decreased $308,000 due to a $654
million increase in average interest-bearing deposits that was offset by a
decrease in the average rate paid on deposits from 5.07% in the second
quarter of 2001 to 2.68% for the comparable period in 2002. The growth in
our deposit base was primarily the result of the Southside acquisition.

         Interest expense on other interest-bearing liabilities increased
$2.08 million in the second quarter of 2002 compared to the second quarter
of 2001. Average short- and long-term borrowings also increased $194.4
million in the first three months of 2002 compared to the year earlier
quarter. The average rate on short-term borrowings decreased 309 basis
points while the rate paid on long-term borrowings decreased 95 basis points
in the second quarter of 2002 compared to the second quarter of 2001.


         Net interest income for the six months ended June 30, 2002 was
$31.41 million, a 77% increase compared to the $17.75 million reported for
the second quarter of 2001. This $13.66 million increase was attributable to
an increase of $921 million in average earning assets primarily from our
September 2001 acquisition of Southside Bancshares Corp. The $17.1 million
increase in interest income was partially offset by a $3.45 million increase
in interest expense.

The increase in interest expense was the result of an $878 million increase
in average interest-bearing liabilities partially offset by a decrease of
224 basis points in the average interest rate paid between the periods.

         Net interest margin for the first six months of 2002 decreased 18
basis points compared to the first six months of 2001. The earning assets
yield decreased 217 basis points while the overall interest rate paid on
interest-bearing liabilities decreased 224 basis points. The net interest
spread increased 7 basis points comparing the year-to-date 2002 to the
year-to-date 2001.

         The following table sets forth for the periods indicated the
changes in interest income and interest expense which were attributable to
change in average volume and changes in average rates. Volume variances are
computed using the change in volume multiplied by the previous year's rate.
Rate variances are computed using the changes in rate multiplied by the
previous year's volume.

         Other Income. Other income increased 77% to $5.96 million in the
second quarter of 2002 compared to $3.37 million for the three months ended
June 30, 2001.

         Service charge income for the three-month period ended June 30,
2002 increased $777,000 or 78%, compared to the second quarter of 2001. This
increase was attributable to an increased deposit base and our focus on
revenue enhancement programs. Gains on the sales of securities increased to
$1.68 million for the quarter ended June 30, 2002 from $383,000 for the
comparable period in 2001.

         For the quarter ended June 30, 2002 mortgage banking revenue was
$969,000 compared to $1.05 million for the quarter ended June 30, 2001.
Income on bank-owned life insurance increased to $416,000 for the three
months ended June 30, 2002 compared to $287,000 for the three months ended
June 30, 2001, primarily due to the Southside acquisition.

         Other income increased 64% to $10.02 million for the first six
months of 2002 compared to $6.13 million for the first six months of 2001.

         Service charge income for the six-month period ended June 30, 2002
increased $1.45 million or 74%, compared to the six-month period ended June
30, 2001. This increase was attributable to an increased deposit base and
our focus on revenue enhancement programs. Gains on the sales of securities
increased to $1.69 million for the six months ended June 30, 2002 from
$915,000 for the comparable period in 2001.

         For the six months ended June 30, 2002 mortgage banking revenue was
$1.80 million compared to $1.54 million for the six-month period ended June
30, 2001. Income on bank-owned life insurance increased to $1.03 million for
the six months ended June 30, 2002 compared to $510,000 for the six months
ended June 30, 2001, primarily due to the Southside acquisition.


      Other Expenses. For the three months ended June 30, 2002 compared
to the second quarter of 2001, other expenses increased 71%, to $11.89
million from $6.95 million. The increased expenses reflected the expenses
related to operating the branches acquired in our business combination with
Southside in September 2001, as well as the five St. Louis branches acquired
from Guardian Savings in December 2001.


          Salaries and employee benefits increased 58% to $6.17 million for
the three months ended June 30, 2002 compared to $3.90 million for the three
months ended June 30, 2001. We had 543 full-time equivalent employees at
June 30, 2002 compared to 318 full-time equivalent employees at June 30,
2001. Total annualized cost per full-time equivalent employee was $45,422
for the three months ended June 30, 2002 compared to $49,094 for the
corresponding period of 2001.

         Expenses associated with occupancy and equipment increased $433,000
and $364,000, respectively, for the three-month period ended June 30, 2002
compared to the second quarter of 2001. These increases were primarily due
to the additional costs associated with operating the Southside and Guardian
branches acquired in 2001.


         Our efficiency ratio was 53.4% for the quarter ended June 30, 2002
compared to 57.5% for the second quarter of 2001.

         For the six-month period ended June 30, 2002, other expenses
increased 67%, to $22.58 million from $13.48 million compared to the
six-month period ended June 30, 2001. The increased expenses reflected the
expenses related to operating the branches acquired in our business
combination with Southside in September 2001, as well as the five St. Louis
branches acquired from Guardian Savings in December 2001.


         Securities Portfolio. Our securities portfolio consists of
securities classified as held-to-maturity and available-for-sale. We
designate these securities at the time of purchase into one of these two
categories. At June 30, 2002, held-to-maturity securities amounted to $19.0
million representing those securities we intended to hold to maturity.
Securities designated as available-for-sale totaled $435.4 million
representing securities which we may sell to meet liquidity needs or in
response to significant changes in interest rates or prepayment patterns.

         For purposes of this discussion, held-to-maturity and
available-for-sale securities are described as the securities portfolio. At
June 30, 2002, the securities portfolio totaled $454.4 million, a decrease
of $9.2 million from December 31, 2001. We maintain a conventional
short-term laddered portfolio investment strategy to provide adequate
liquidity while minimizing interest rate risk.

         Loans. Loans historically have been the primary component of
earning assets. At June 30, 2002, loans totaled $1.5 billion, an increase of
6% from year-end 2001. Substantially all of these loans were originated in
our market area. At June 30, 2002, we had no foreign loans and only a
minimal amount of participations purchased.

         Multi-family and commercial real estate mortgage loans showed the
largest increase of $58.3 million during the first six months of 2002. The
increase in these loans reflected our efforts to grow our commercial real
estate loan portfolio, including loans originated by our expanded commercial
lending staff. Multi-family and commercial real estate mortgage loans
comprised 44.1% of the portfolio at June 30, 2002 compared to 42.8% at
year-end 2001. Real estate construction loans increased $27.4 million during
the first six months of 2002. The increase in construction loans was
primarily related to residential projects to experienced home builders in
the St. Louis market. Consumer loans decreased $11.6 million or 14.5% as our
lending focus continues to be weighted more toward commercial loans.

         The following table summarizes the composition of our loan
portfolio at the dates indicated:

         Asset Quality. Non-performing assets consist of the following:
non-accrual loans on which the ultimate collectibility of the full amount of
interest is uncertain; loans which have been renegotiated to provide for a
reduction or deferral of interest or principal because of a deterioration in
the financial condition of the borrower; loans past due 90 days or more as
to principal or interest; and other real estate owned. Non-performing assets
decreased to $15.5 million at June 30, 2002 compared to $17.3 million at
March 31, 2002, and $20.1 million at December 31, 2001. At June 30, 2002,
non-performing assets represented 0.70% of total assets compared to 0.80% at
March 31, 2002, and 0.93% at December 31, 2001. Non-accrual loans totaled
$13.5 million at June 30, 2002 compared to $15.3 million at March 31, 2002,
and $14.5 million at December 31, 2001. During the first six months of 2002,
we received principal reductions totaling $2.1 million on two of these
credits and their remaining balance of $3.2 million returned to performing
assets. We have charged off $2.3 million on two of the other non-performing
credits. The three remaining relationships from year-end were acquired from
Southside. During the first six months of 2002, we added one significant
loan relationship totaling $3.5 million to non-performing assets. We expect
the deficiencies in this loan relationship to be addressed prior to the end
of 2002. We continue to work aggressively to collect all non-performing
assets.

         We continually analyze our loan portfolio to identify potential
risk elements. The loan portfolio is reviewed by lending management and the
banks' internal loan review staff. As an integral part of their examination
process, the various regulatory agencies periodically review our allowance
for loan losses.

         Allowance for Loan Losses. The provision for loan losses was $3.5
million during the first six months of 2002 compared to $1.7 million for the
first six months of 2001. Net charge-offs were $4.1 million for the
six-month period ended June 30, 2002 compared to $765,000 for the first six
months of 2001. Net charge-offs for the first six months of 2002 represented
0.27% of average loans, compared to 0.09% for the first six months of 2001.

         The allowance for loan losses totaled $18.3 million at June 30,
2002 compared to $18.9 million at December 31, 2001 and $12.4 million at
June 30, 2001. As a percentage of loans outstanding, the allowance
represented 1.21% of loans at June 30, 2002 compared to 1.33% at December
31, 2001, and 1.40% at June 30, 2001.

         The higher provision and net charge-offs were the result of our
efforts to identify and recognize potential losses in our loan portfolio.
Since 1998, we have changed the composition of the loan portfolio and
shifted our lending focus to higher yielding commercial relationships. This
shift, while providing higher earnings potential, does entail greater risk
than traditional residential mortgage loans. Specific allowances have been
increased on certain commercial real estate loans based on individual
reviews of these loans and our estimate of the borrower's ability to repay
the loan given the availability of collateral, other sources of cash flow
and collection options available to us.

         The allowance for loan losses is provided at a level considered
adequate to provide for potential losses and, among other things, is based
on management's evaluation of the anticipated impact on the loan portfolio
of current economic conditions, changes in the character and size of the
loan portfolio, evaluation of potential problem loans identified based on
existing circumstances known to management and recent loan loss experience.
We continually monitor the quality of the loan portfolio to ensure the
timely charge-off of problem loans and to determine the adequacy of the
level of the allowance for loan losses. We presently believe that our asset
quality, as measured by the statistics in the following table, continues to
be very high and that our allowance is adequate to absorb potential losses
inherent in the portfolio at June 30, 2002.

         Deposits. Total deposits increased $731.1 million or 84%, at June
30, 2002 compared to June 30, 2001. The increase in deposits was primarily
the result of the Southside acquisition. Non interest-bearing deposits
totaled $175.2 million at June 30, 2002. We have been successful in
expanding our deposit base while maintaining our focus on personal service.
Our lending officers have increased commercial deposits while our retail
banking staff continues efforts to increase our core deposits.

LIQUIDITY MANAGEMENT AND CAPITAL RESOURCES

         Liquidity Management. Long-term liquidity is a function of the core
deposit base and an adequate capital base. We are committed to growth of our
core deposit base and maintenance of our capital base. The growth of the
deposit base is internally generated through product pricing and product
development. In addition, we periodically raise funds through brokered
certificates of deposit. Both of these elements contributed to developing
and maintaining our long-term liquidity. Our capital position has been
maintained through earnings retention and raising of capital. See "Capital
Resources."

         Short-term liquidity needs arise from continuous fluctuations in
the flow of funds on both sides of the balance sheet resulting from growth
and seasonal and cyclical customer demands. The securities portfolio
provides stable long-term earnings as well as being a primary source of
liquidity. The designation of securities as available-for-sale and
held-to-maturity does not impact the portfolio as a source of liquidity due
to the ability to transact repurchase agreements using those securities.

         We anticipate continued loan demand in our market area as the
banking industry consolidation continues. We have utilized, and expect to
continue to utilize, Federal Home Loan Bank borrowings to fund a portion of
future loan growth. We have a $351.3 million secured credit facility with
the Federal Home Loan Bank, under which $300.0 million and $190.2 million
was outstanding at June 30, 2002 and December 31, 2001, respectively. We
continue to utilize Federal Home Loan Bank borrowings to fund loan growth
while systematically seeking to build our deposit base. We anticipate
similar use of the Federal Home Loan Bank credit facility in the foreseeable
future.

         Our assets and deposits remained relatively the same from December
31, 2001 to June 30, 2002. We strive to grow our core deposits while
utilizing Federal Home Loan Bank borrowings, federal funds purchased and
brokered certificates of deposit as necessary to balance liquidity and cost
effectiveness. We closely monitor our level of liquidity in view of expected
future needs.


         Capital Resources. Total shareholders' equity was $154.3 million at
June 30, 2002, compared to $138.1 million at year-end 2001. The increase in
total equity was primarily the result of earnings retention, stock options
exercised for our common stock and an increase during the first six months
of 2002 of $3.7 million in net gains on available-for-sale securities.


         Our capital requirements historically have been financed through
offerings of debt and equity securities, retained earnings and borrowings
from a commercial bank. Our subsidiary banks also utilize their borrowing
capacity with the Federal Home Loan Bank. The principal amount of our term
loan was $36.5 million as of June 30, 2002, and matures in September 2002 at
which time we expect to renew this term loan. Allegiant Bank also utilizes
its borrowing capacity with the Federal Home Loan Bank.

         From time to time, we have purchased brokered certificates of
deposit in order to fund loan growth and meet other liquidity needs. We have
not had any brokered deposits since May 2001, but we may use brokered
deposits in the future as a source of liquidity.

         Dividends paid during the second quarter of 2002 were $0.065 per
share, an increase of 8% compared to the $0.06 per share paid for the second
quarter of 2002. Our dividend payout ratio was 19.9% for the first six
months of 2002.

         We also analyze our capital and the capital position of our banks
in terms of regulatory risked-based capital guidelines. This analysis of
capital is dependent upon a number of factors including asset quality,
earnings strength, liquidity, economic conditions and combinations thereof.
The Federal Reserve Board has issued standards for measuring capital
adequacy for bank holding companies. These standards are designed to provide
risk-responsive capital guidelines and to incorporate a consistent framework
for use by financial institutions. Our management believes that, as of June
30, 2002, we and our subsidiaries met all capital adequacy requirements. We
will seek to maintain a strong equity base while executing our controlled
expansion plans.

         As of June 30, 2002, December 31, 2001 and June 30, 2001,
Allegiant's and Allegiant Bank's capital ratios were as follows:

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

         There have been no material changes from the information provided
in our Annual Report on Form 10-K for the year ended December 31, 2001.

PART II. OTHER INFORMATION

ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

         Our 2002 annual meeting of shareholders was held on April 18, 2002.
Of 15,501,206 shares issued, outstanding and eligible to be voted at the
meeting, holders of 11,926,312 shares, constituting a quorum, were
represented in person or by proxy at the meeting. Three matters were
submitted to a vote of the security holders at the meeting.

         1. ELECTION OF CLASS II DIRECTORS. The election of four Class II
director nominees to our board of directors, each to continue in office
until the year 2005. Our Articles of Incorporation, as amended, 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 four
director nominees had been elected. The voting results are set forth below:

                  NAME                     FOR          AGAINST      WITHHELD
                  ----                     ---          -------      --------
                Robert L. Chambers      11,931,491         0          387,970
                Leland B. Curtis        12,014,157         0          305,319
                Shaun R. Hayes          11,679,134         0          640,327
                John L. Weiss           12,041,476         0          277,985

         Because our company has a staggered board, the terms of office of
the following named Class III and Class I directors continued after the
meeting:

                  CLASS III (TO CONTINUE IN OFFICE UNTIL 2003)
                  --------------------------------------------

                  C. Virginia Kirkpatrick
                  Marvin S. Wool

                  CLASS I (TO CONTINUE IN OFFICE UNTIL 2004)
