                   Notes to Consolidated Financial Statements

NOTE 1 - General

The consolidated financial statements in this report have not been audited,
except for the Condensed Consolidated Statement of Condition dated December 31,
1998. In the opinion of management, all adjustments necessary to present fairly
the financial position, the results of operations and the statement of cash
flows for the interim periods have been made. All such adjustments are of a
normal recurring nature. The results of operations are not necessarily
indicative of the results of operations for the full year or any other interim
periods. For further information, refer to the consolidated financial
statements and footnotes included in the Corporation's annual report on Form
10-K for the year ended December 31, 1998.

NOTE 2 - New Accounting Pronouncements

Earnings per share are computed in accordance with Statement of Financial
Accounting Standards (SFAS) No. 128, "Earnings Per Share." SFAS No. 128
requires the replacement of previously reported primary and fully diluted
earnings per share under Accounting Principles Board Opinion No. 15 with basic
earnings per share and diluted earnings per share. Basic earnings per share are
computed on the weighted average number of shares outstanding. As of March 31,
1999 the Company did not have stock option plans or other stock-based
compensation plans that would result in potential common shares and thus
diluted earnings per share for the quarter were identical to basic earnings per
share. The stockholders of the Corporation approved the United Bancorporation
of Alabama, Inc. Stock Option Plan at the Annual Meeting of Stockholders on May
5, 1999, pursuant to which stock options had been granted subject to
stockholder approval.

Effective January 1, 1998, the Corporation adopted the SFAS No. 130 "Reporting
Comprehensive Income", which requires disclosure, in financial statement
format, all non-owner changes in equity. Adoption of this statement requires
the presentation of comprehensive income, which includes the unrealized gain of
loss on investment securities.

In June 1997, the FASB issued SFAS 131, "Disclosures about Segments of an
Enterprise and Related Information". SFAS 131 establishes new standards for the
disclosures about operating segments. Disclosure of selected information about
operating segments. It also establishes standards for related disclosures about
products and services, geographic areas, and major customers. SFAS 131 is
effective for financial statements for years beginning after December 15, 1997.
The Corporation operates in only one segment - commercial banking.

In June 1998, the FASB issued SFAS 133, "Accounting for Derivative Instruments
and Hedging Activities", SFAS 133 establishes accounting and reporting
standards for derivative instruments, including certain derivative instruments
embedded in other contracts, and for hedging activities. It requires that an
entity recognizes all derivatives as either assets or liabilities in the
statement of financial position and measure those instruments at fair value.
SFAS 133 is effective for financial statements for the first quarter of fiscal
years beginning after June 15, 1999. Management is evaluating the impact of
SFAS 133 on the financial statements of the Corporation.

Note 3 - Subsequent Events

On May 5, 1999, the Corporation announced a two-for-one stock split to be
effected in the form of stock dividend payable May 17, 1999 to shareholders of
record on April 30, 1999. Basic earnings per share on a restated basis was
$0.42 for March 31, 1999 and $0.41 for March 31, 1998.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS

Results of Operations

The following financial review is presented to provide an analysis of the
results of operations of United Bancorporation of Alabama, Inc. (the
"Corporation"), and its subsidiary for the three months ended March 31, 1999,
and 1998, comparatives. This review should be used in conjunction with the
consolidated financial statements included in the Form 10-Q.

Net income after taxes for the three months ended March 31, 1999, increased
$10,838, or 2.55%, as compared to the same period in 1998. This increase is a
result of a lower effective tax rate due to a higher level of tax exempt
income.

Total interest income increased by $349,645, or 10.47% in 1999. This increase
was caused by loan interest income increasing $445,276 or 19.88% and a decrease
of $95,631 or 8.68% in income from other interest earning assets. Average
interest earning assets were $184,624,977 for the first quarter of 1999 as
compared to $161,247,219 for the same period in 1998, an increase of
$23,377,758 or 14.50%. The average rate earned in 1999 was 8.11% as compared to
8.40% in 1998, reflecting the lowering of rates by the Federal Reserve in the
fall of 1998, and resulting in higher yielding bonds being called in the latter
part of 1998. Thus, the majority of the increase in total interest income in
1999 is attributed to the increase in volume of earning assets. The net
interest margin increased to 4.47% for the first quarter of 1999, as compared
to 4.43% for the same period in 1998.

Total interest expense increased by $76,931, or 4.88%, in 1999. Average
interest bearing liabilities increased to $152,999,633 in 1999, from
$142,466,082 in 1998, an increase of $10,533,551, or 7.39%. The average rate
paid during the first quarter of 1999 was 4.39% as compared to 4.80% for the
same period in 1998. The increase in interest expense is attributed to the
increase in interest bearing liabilities but was affected somewhat by the
decrease in the interest rate paid. The Bank received approximately 15,000,000
in 1998, in interest bearing checking accounts based on a floating rate of
61.8% of prime. The account is currently paying 4.79%. These deposits were a
competitive bid on public funds, the contract runs for three years.

The provision for loan losses increased to $199,000 for the first three months
of 1999, as compared to $60,000 for the same period in 1998. The growth in the
provision for loan loss of 231.66% was due to the growth in the loan portfolio
of $13,510,817. The allowance for loan losses is maintained at a level which,
in management's opinion, is appropriate to provide for estimated losses in the
portfolio at the balance sheet date. Factors considered in determining the
adequacy of the allowance include historical loan loss experience, the amount
of past due loans, loans classified from the most recent regulatory
examinations and internal reviews, general economic conditions and the current
portfolio mix. The amount charged to operating expenses is that amount
necessary to maintain the allowance for loan losses at a level indicative of
the associated risk, as determined by management, of the current portfolio.


                                       8
<PAGE>   9

The allowance for loan losses consists of two portions: the classified portion
and the nonclassified portion. The classified portion is based on identified
problem loans and is calculated based on an assessment of credit risk related
to those loans. Specific loss estimate amounts are included in the allowance
based on assigned classifications as follows: substandard (10%), doubtful
(50%), and loss (100%).

The nonclassified portion of the allowance is for inherent losses which
probably exist as of the evaluation date even though they may not have been
identified by the more objective processes for the classified portion of the
allowance. This is due to the risk of error and inherent imprecision in the
process. This portion of the allowance is particularly subjective and requires
judgments based upon qualitative factors which do not lend themselves to exact
mathematical calculations. Some of the factors considered are changes in credit
concentrations, loan mix, historical loss experience, and general economic
environment in the Corporation's markets.

While the total allowance is described as consisting of a classified and a
nonclassified portion, these terms are primarily used to describe a process.
Both portions are available to support inherent losses in the loan portfolio.
Management realizes that general economic trends greatly effect loan losses,
and no assurances can be made that future charges to the allowance for loan
losses will not be significant in relation to the amount provided during a
particular period, or that future evaluations of the loan portfolio based on
conditions then prevailing will not require sizable charges to income.
Management does, however, consider the allowance for loan losses to be
appropriate for the reported periods.

Net charged-off loans for the first quarter of 1999 were $55,889, as compared
to $148,534 net charge-offs in the first quarter of 1998.

The allowance for loan losses represents 1.33% of gross loans at March 31,
1999, as compared to 1.37% at year-end 1998. Loans on which the accrual of
interest had been discontinued amounted to $395,814 at March 31, 1999, as
compared to $420,192 at December 31, 1998.

Total non-interest income increased to $389,226 for the first quarter of 1999,
as compared to $337,767 for the same period of 1998, an increase of $51,459, or
15.24%. Service charges on deposits increased $21,865, or 9.06%. Commissions on
credit life increased by $4,748 in 1999, or 4.12%. Other income increased
during the first quarter of 1999 to $87,817 from $84,996 in 1998 or 3.32%.

Total non-interest expense increased $200,496, or 13.82% during the first
quarter of 1999. Salaries and benefits increased $132,083 or 16.72% in 1999.
The Corporation has added one new branch since March of 1998, which accounted
for a majority of the increase in salaries and benefits. Occupancy expense
decreased $5,351, or 2.45%. Other expense increased $63,714 or 14.40% during
the first quarter of 1999. The majority of this increase can be traced to
professional services that increased $19,692 and supplies, which increased
$15,684.


                                       9

Earnings before taxes for the first quarter of 1999 decreased $15,323, or
2.59%, compared to the same period of 1998. Income tax expense decreased to
$139,784 in 1999 from $165,945 in 1998, a decrease of $26,161, or 15.76%. The
effective tax rate decreased from 28.08% to 24.29% as a result increased
interest income from tax-free bonds.

Financial Condition and Liquidity

Total assets on March 31, 1999, had increased $9,425,951 or 4.75% as compared
to December 31, 1998. Average total assets for the first quarter of 1999 were
$196,037,952 as compared to $171,119,129 for the same period in 1998. Net loans
increased by $13,394,333 or 12.99% at March 31, 1999, from December 31, 1998.
This growth in loans has occurred in the Baldwin County markets of the
Corporation, and the growth is primarily in the commercial real estate type
loans. The net loan to deposit ratio on March 31, 1999 was 73.78%, as compared
to 68.46% on December 31, 1998.

Fed Funds Sold decreased $645,000 as of March 31, 1999, as the bank has a
borrowed position in Fed Funds, due to loan demand exceeding deposit growth. At
the end of March the Corporation had $4,905,000 in federal funds borrowed at a
rate of 4.98%. The investment securities available for sale decreased by
$1,383,271 or 2.55% in the first quarter of 1999, from December 31, 1998. The
investment securities held to maturity decreased by $563,528 or 3.31% at March
31, 1999 from December 31, 1998.

Non-performing Assets: The following table sets forth the Corporation's
non-performing assets at March 31, 1999 and December 31, 1998. Under the
Corporation's nonaccrual policy, a loan is placed on nonaccrual status when
collectibility of principal and interest is in doubt or when principal and
interest is 90 days or more past due.

Total deposits increased $5,055,061, or 3.31%, at March 31, 1999, from December
31, 1998. Non-interest bearing deposits decreased $628,564 or 2.33% at quarter
end from the year-end total. Interest bearing deposits increased $5,683,625, or
4.52%, at March 31, 1999, from December 31, 1998. Average total deposits for
the first quarter of 1999 were $157,187,762, as compared to $141,084,491 for
the same period in 1998.

The Corporation relies primarily on internally generated capital growth to
maintain capital adequacy. Total stockholders' equity on March 31, 1999, was
$16,277,651, an increase of $229,676, or 1.43%, from $16,047,975 at year-end
1998.

Primary capital to total assets at March 31, 1999, was 8.19%, as compared to
8.48% at year-end 1998. Total capital and allowances for loan losses to total
assets at March 31, 1999, were 8.99%, as compared to 9.24% at December 31,
1998. The Corporation's bank subsidiary, United Bank, had risk based capital of
$17,137,000, or 13.89%, at March 31, 1999, as compared to $16,557,000, or
14.85% at year end 1998. The minimum requirement is 8.00%. Based on
management's projection, internally generated capital should be sufficient to
satisfy capital requirements in the foreseeable future, for existing
operations, but the continual growth into new markets may require the Bank to
access external funding sources.

Year 2000 Issues

The Federal Financial Institutions Examination Council (FFIEC) issued an
interagency statement on May 5, 1997, providing an outline for institutions to
effectively manage Year 2000 challenges. As a result, the Bank formed its Year
2000 committee in May of 1997. The board of directors has established Year 2000
compliance as a strategic initiative. The Bank has also established an ongoing
action plan designed to ensure that its operational and financial systems will
not be adversely effected by software failures due to processing errors
resulting from the Year 2000 issues. The status of the Bank's initiative as of
March 31, 1999 is as follows:

         PROBLEM AWARENESS-The Bank is aware of the problems that could
         potentially arise from Year 2000 problems and has analyzed internal
         systems (information technology and non-information technology) as
         well as services provided by third parties. The Bank will maintain
         initiatives focusing on customer awareness throughout 1999.


                                      11
<PAGE>   12

         ASSESSMENT PHASE-The Bank has identified all mission critical
         applications and determined the respective systems which were not Year
         2000 compliant. The Bank's third party service providers have been
         contacted to determine their Year 2000 status. The Bank is in the
         process of reviewing test results to determine if the providers are
         Year 2000 compliant. These results should be completed by the end of
         the second quarter.

         RENOVATION PHASE-As of March 31, 1999, the renovation of all mission
         critical systems, other than the Bank's third party  data processing
         center, was essentially complete. The Bank's third party data
         processing center is currently reviewing testing results from late
         March and early April testing and is expected to complete its
         renovation phase in the second quarter.

         VALIDATION-The only mission critical system for which testing
         renovation is currently not complete, is the Bank's third party data
         processing center, is expected to be completed by June of 1999.

         IMPLEMENTATION-Replacement of non-compliant mission critical systems
         is essentially complete. Results from testing, all of which has been
         completed, will be thoroughly reviewed and remedial actions, if
         necessary, will be taken.

Through March 31, 1999, the Bank has incurred approximately $18,689 in
conjunction with its Year 2000 efforts. Additional expenditures are expected to
approximate $48,000. The Bank's internal costs associated with the Year 2000
have not been separately identified. The Bank has an established contingency
plan with the third party data processing center, as well as for internal
operations. Which has been tested for Year 2000 issues.

Item 3. Market Risk Disclosures

Market risk is the risk of loss from adverse changes in market prices and
rates. The Bank's market risk arises principally from interest rate risk
inherent in its lending, deposit and borrowing activities. Management actively
monitors and manages its interest rate risk exposure. Although the Bank manages
other risk, such as credit quality and liquidity risk, in the normal course of
business, management considers interest rate risk to be its most significant
market risk. Interest rate risk could potentially have the largest material
effect on the Bank's financial condition and results of operations. Other types
of market risks, such as foreign currency exchange rate risk and commodity
price risk, do not arise in the Bank's normal course of business activities.

The Bank's profitability is affected by fluctuations in interest rates.
Management's goal is to maintain a reasonable balance between exposure to
interest rate fluctuations and earnings. A sudden and substantial increase in
interest rates may adversely impact the Bank's earnings to the extent that the
interest rates on interest-earning assets and interest-bearing liabilities do
not change at the same speed, to the same extent or on the same basis.


                                      12
<PAGE>   13

The Bank's Asset Liability Management Committee ("ALCO") monitors and considers
methods of managing the rate and sensitivity repricing characteristics of the
balance sheet components consistent with maintaining acceptable levels of
changes in the net portfolio value ("NPV") and net interest income. NPV
represents the market values of portfolio equity and is equal to the market
value of assets minus the market value of liabilities, with adjustments made
for off- balance sheet items over a range of assumed changes in market interest
rates. A primary purpose of the Bank's ALCO is to manage interest rate risk to
effectively invest the Bank's capital and to preserve the value created by its
core business operations. As such, certain management monitoring processes are
designed to minimize the impact of sudden and sustained changes in interest
rates on NPV and net interest income.

The Bank's exposure to interest rate risk is reviewed on a quarterly basis by
the Board of Directors and the ALCO. Interest rate risk exposure is measured
using interest rate sensitivity analysis to determine the Bank's change in NPV
in the event of hypothetical changes in interest rates. Further, interest rate
sensitivity gap analysis is used to determine the repricing characteristics of
the Bank's assets and liabilities. The ALCO is charged with the responsibility
to maintain the level of sensitivity of the Bank's net interest margin within
Board approved limits.

Interest rate sensitivity analysis is used to measure the Bank's interest rate
risk by computing estimated changes in NPV of its cash flows from assets,
liabilities, and off-balance sheet items in the event of a range of assumed
changes in market interest rates. This analysis assesses the risk of loss in
market risk sensitive instruments in the event of a sudden and sustained 100 -
400 basis points increase or decrease in the market interest rates. The Bank
uses the Sendero Model Level II, which takes the current rate structure of the
portfolio and shocks for each rate level and calculates the new market value
equity at each level. The Bank's Board of Directors has adopted an interest
rate risk policy, which establishes maximum allowable decreases in net interest
margin in the event of a sudden and sustained increase or decrease in market
interest rates. The following table presents the Bank's projected change in NPV
for the various rate shock levels as of March 31, 1999. All market risk
sensitive instruments presented in this table are held to maturity or available
for sale. The Bank has no trading securities.

</TABLE>

The preceding table indicates that at March 31, 1999, in the event of a sudden
and sustained increase in prevailing market interest rates, the Bank's NPV
would be expected to decrease, and that in the event of a sudden decrease in
prevailing market interest rates, the Bank's NPV would be expected to increase.
The recent growth in loans has caused the caused the Corporation to become more
liability sensitive over the period of a year, but the net interest margin
remains stable in all interest rate environments tested.
