               Noted to Interim Consolidated Financial Statements

Note 1  - General

The interim consolidated financial statements in this report have not been
audited. In the opinion of management, all adjustments necessary to present
fairly the financial position and the results of operations 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 Company's annual report on Form 10-K for the year ended December
31, 1997.


NOTE 2 - New Accounting Pronouncement

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 income per share is computed on the
weighted average number of shares outstanding in accordance with SFAS 128
Earnings per Share. The Company does not have stock options plans or other stock
based compensation plans that would result in potential common shares and thus
diluted earnings per share are identical to basic earnings per share.

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

In June, 1997 the FASB Issued Financial Accounting Statement No. 131,
Disclosures about Segments of an Enterprise and Related Information,
("FAS131"). FAS131 requires that financial and descriptive information be
disclosed for each reportable operating segment based on the management
approach. The management approach focuses on financial information that an
enterprise's decision makers use to assess performance and make decisions about
resource allocation. The statement also prescribes the enterprise-wide
disclosures to be made about products, services, geographic areas and major
customers. FAS131 is effective for annual financial

                                       6

statements issued for periods beginning after December 15, 1997, and for interim
financial statements in the second year of application. The Company adopted
FAS131 as of January 1, 1998.

In June, 1998, the FASB issued Financial Accounting Statement No. 133,
Accounting for Derivative Instruments and Hedging Activities, ("FAS133"). FAS133
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 reorganize all derivatives as
either assets or liabilities in the statement of financial position and measure
those instruments at fair value. This Statement is effective for all fiscal
quarters of fiscal years beginning after June 15, 1999. Presently, the
Corporation is unable to quantify the impact that the adoption of FAS 133 will
have on the consolidated financial statements of the Corporation.

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 six months ended June 30, 1998, and
1997, compared. This review should be used in conjunction with the consolidated
financial statements included in the Form 10-Q.

Net income for the six months ended June 30, 1998, was $837,249 a decrease of
$42,219, or 4.80%, as compared to $879,468 for the same period in 1997. Net
earnings per share decreased to $1.62 for the six months ended June 30, 1998, as
compared to $1.70 in 1997.

Total interest income increased $1,020,365, or 17.30%, to $6,918,424 in 1998
from $5,898,059 in 1997. Average interest earning assets were $178,655,696 for
the first six months 1998, as compared to $140,940,674 for the same period in

8.29% as compared to 8.44% in 1997, reflecting slightly lower interest rates
during 1998. Thus, the increase in total interest income in 1998 is attributed
to both the increase in earning assets, and not to the rate environment. Net
interest margin decreased to 4.33% for the first six months of 1998 as compared
to 4.72% for the same period in 1997. This decrease has been caused by the
flatting of the yield curve, which has caused bond and loans rates to drop and
deposit costs have risen. Therefore compressing net interest margin.

from $2,597,615 in 1997. Average interest bearing liabilities increased to

charged-off loans for the first six months of 1998 were $146,395, as compared to
$55,380 for the same period in 1997.

30, 1998, as compared to 1.65% at year-end 1997. Loans on which the accrual of
interest had been discontinued was reduced to $307,548 at June 30, 1998, as

the second quarter of 1998 was 8.19%, as compared to 8.52% for the same period
in 1997. Therefore the increase in interest earning is due to the increase in
earning assets. The net interest margin decreased to 4.36% for the second

The Corporation relies primarily on internally generated capital growth to
maintain capital adequacy. Total stockholders' equity on June 30, 1998, was
$15,197,214, an increase of $570,155, or 3.89%, from $14,627,059 at year end
1997. This increase is due to earnings, the slight decline of the market value
of the available for sale portfolio, and the dividend declared of $258,193 at
June 30, 1998.

Primary capital to total assets at June 30, 1998, was 8.19%, as compared to
8.89% at year end 1997. Total capital and allowances for loan losses to total
assets at June 30, 1998, were 8.95%, as compared to 9.76% at December 31, 1997.
The Corporation's bank subsidiary, United Bank, had risk based capital of
$15,713,000, or 15.16%, at June 30, 1998, as compared to $15,316,000, or 16.24%
at year end 1997. United Bank had excess risk based capital of 7.16% at June 30,
1998, and 8.24% at December 31, 1997, based upon the minimum requirement of
8.00%. Based on management's projection, internal 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.
