         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 it is made clear that it means only
Allegiant. Also, sometimes we refer to our bank subsidiaries as the "banks."

                                     PART I

ITEM 1. BUSINESS

GENERAL

         We are a bank holding company headquartered in St. Louis, Missouri.
Our bank subsidiaries, Allegiant Bank, Bank of Ste. Genevieve, Bank of
St. Charles County and State Bank of Jefferson County offer full-service
banking, wealth management and personal trust services to individuals,
commercial businesses and municipalities through our 39 full-service banking
locations in the St. Louis, Missouri 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 deposit
boxes. As of December 31, 2001, we reported, on a consolidated basis, total
assets of $2.2 billion, loans of $1.4 billion, deposits of $1.7 billion and
shareholders' equity of $138.1 million.

         Since our inception in 1989, we have been committed to building a
strong, customer-friendly community bank. As a community bank, we are able
to respond quickly to our customers through local decision-making and to
tailor products and services to meet their needs. We believe this
customer-friendly approach provides us with a competitive advantage over
many of the larger financial institutions in the St. Louis metropolitan
area. In addition, we believe that we have benefited from recent
acquisitions of locally headquartered financial institutions by larger
regional or national out-of-town financial institutions. Recent acquisitions
of financial institutions in our market area include: Bank America
Corporation's acquisition of Boatmen's Bancshares, Inc.; Union Planters
Corporation's acquisition of Magna Group, Inc.; and Firstar Corporation's
(now known as U.S. Bancorp) acquisition of Mercantile Bancorporation Inc.

         We are the largest publicly owned bank holding company exclusively
serving St. Louis, which is the 18th largest metropolitan area in the United
States with a population of approximately 2.6 million. We are also the
largest bank holding company in the St. Louis area. We have grown rapidly
through a combination of internal growth and acquisitions of other financial
institutions. We believe that market coverage is necessary, and our goal is
to have a banking facility within a 20-minute drive from all principal
sectors of the St. Louis metropolitan area.

         In 1989, we acquired Allegiant State Bank located in Northeastern
Missouri. We acquired Allegiant Bank in St. Louis, Missouri in 1990. In
January 1995, Allegiant State Bank was merged into Allegiant Bank. We
acquired Reliance Savings and Loan Association of St. Louis County in August
1997 and later merged it into Allegiant Bank. In September 1997, Allegiant
Bank acquired two branches in Union and Warrenton, Missouri from Roosevelt
Bank.

         In November 2000, we acquired Equality Bancorp, Inc. Equality
Bancorp was the parent of Equality Savings Bank which was founded in 1884
and was the oldest thrift in the State of Missouri. At the time of closing,
Equality Bancorp had consolidated assets of approximately $300.4 million. In
connection with our acquisition of Equality Bancorp, we issued approximately
2.7 million shares of our common stock. Based upon the net book value of the
Equality Bancorp assets at closing, no goodwill was recorded.

         On September 28, 2001, we acquired Southside Bancshares Corp.
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 useful life of 10 years and none of this amortization is
expected to be deductible for tax purposes. As a result of the Southside
acquisition, the number of Allegiant outstanding shares increased to
approximately 15.2 million at December 31, 2001.

                                     2

         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. In accordance with
current accounting standards, we will amortize this premium paid for
thrift branches over an estimated useful life of ten years. This
amortization is expected to be deductible for tax purposes. We believe the
acquisition of Southside and the Guardian branches helped us to create a
strategically, operationally and financially strong company that is
positioned for further growth and will be able to compete effectively and
offer personalized banking products and services in the St. Louis
community.

         Since the beginning of 1998, we have focused primarily on improving
the profitability of our banking operations. As a result, we have reduced
the amount of one- to four-family mortgages that we hold in our loan
portfolio and increased the amount of higher yielding commercial loans. We
also have hired over 20 banking professionals each with more than 10 years
experience in the St. Louis metropolitan area to help us grow our commercial
loans and deposits. We have refined our market focus to concentrate
exclusively on opportunities in the higher growth St. Louis metropolitan
area and, accordingly, we sold three retail banking offices outside the
St. Louis metropolitan area in December 1998. We also have implemented
company-wide, cost-control efforts to enhance efficiencies throughout our
entire operation.

         Our management team is comprised of experienced individuals who
average more than 15 years in the banking or financial services industries.
As of March 8, 2002, our directors and executive officers owned
approximately 24% of our outstanding common stock.

FINANCIAL SUMMARY OF THE COMPANY

         A consolidated financial summary of our company and subsidiaries,
included on page 9 in our 2001 Annual Report to Shareholders, is
incorporated herein by reference.

SUBSIDIARIES

         The table setting forth the names and states of incorporation or
organization, as the case may be, of our subsidiaries is included as Exhibit
21 hereto.

OPERATIONS

         Our bank subsidiaries offer complete banking and trust services to
individuals, businesses and municipalities in the St. Louis metropolitan
area. Services include commercial, real estate and installment loans,
checking, savings and time deposit accounts, trust and other fiduciary
services, private banking and various other customer services such as
brokerage, insurance and safe deposit boxes.

COMPETITION

         We operate in a competitive environment. In the St. Louis
metropolitan area, other commercial banks, savings and loan associations,
credit unions, finance companies, mutual funds, insurance companies,
brokerage and investment banking firms and other financial intermediaries
offer similar services. Many of these competitors have substantially greater
resources and lending limits and may offer certain services we do not
currently provide. In addition, some of our non-bank competitors are not
subject to the same extensive regulations that govern us, Allegiant Bank and
our other subsidiaries. Our profitability depends upon the ability of our
subsidiary banks to compete in our market area.

SUPERVISION AND REGULATION

         Financial institutions and their holding companies are extensively
regulated under federal and state law. As a result, our growth and earnings
performance can be affected not only by management decisions and general
economic conditions, but also by the requirements of applicable state and
federal statutes and regulations and the policies of various government
regulatory authorities, including the Missouri Division of Finance, the
Federal Reserve Board, the Federal Deposit Insurance Corporation, the
Internal Revenue Service, state taxing authorities and the Securities and
Exchange Commission. We cannot predict with a high degree of certainty the
effect of applicable statutes, regulations and regulatory policies on us,
but believe that it could be significant.

         Federal and state laws and regulations generally applicable to
financial institutions regulate, among other things, the scope of business,
investments, reserves against deposits, capital levels relative to
operations, the nature and amount of collateral for loans, the establishment
of branches, mergers, consolidations and dividends. The system of
supervision and regulation applicable to us establishes a comprehensive
framework for our operations and is intended primarily for the protection of
the FDIC's deposit insurance funds and the depositors of our subsidiary
banks rather than our shareholders.

         This summary of the material elements of this regulatory framework
does not describe all applicable statutes, regulations and regulatory
policies, nor does it restate all of the requirements of the statutes,
regulations and regulatory policies that are described. You should review
the applicable statutes, regulations and regulatory policies. Any changes in
applicable law, regulations or regulatory policies may have a material
effect on our business.

         Legislation recently enacted by Congress allows bank holding
companies to engage in a wider range of non-banking activities, including
additional securities and insurance activities. The expanded powers
generally would be available to a bank holding company only if the bank
holding company and its bank subsidiaries remain well-capitalized and
well-managed. At this time, we are unable to predict the full impact that
this legislation may have on us.

EMPLOYEES

         As of December 31, 2001, we had approximately 560 full-time
equivalent employees. None of our employees are subject to a collective
bargaining agreement. We consider our relationship with our employees and
those of our subsidiary banks to be good.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING
        AND FINANCIAL DISCLOSURE

         On September 28, 2001, we acquired Southside Bancshares Corp. For
tax reasons, the form of the transaction called for us to merge into
Southside. However, for all other aspects, the surviving company was
effectively Allegiant. On October 4, 2002, we filed a report on form 8-K to
report, pursuant to item 4 thereof, the dismissal of KPMG LLP as the
surviving company's independent auditors for the year ended December 31,
2001 and the appointment of Ernst & Young LLP to replace KPMG. Prior to the
merger with Southside, Ernst & Young LLP served as our independent auditors
