         The Consolidated Condensed Financial Statements were prepared by the
Company without an audit, but in the opinion of management, reflect all
adjustments necessary for the fair presentation of the Company's financial
position and results of operations for the nine month periods ended September
30, 1997 and 1996. Results of operations for the interim 1997 period are not
necessarily indicative of results expected for the full year. While certain
information and footnote disclosures normally included in financial statements
prepared in accordance with generally accepted accounting principles have been
condensed or omitted pursuant to the rules and regulations of the Securities
and Exchange Commission, the Company believes that the disclosures herein are
adequate to make the information presented not misleading. These condensed
financial statements should be read in conjunction with the Consolidated
Financial Statements and the notes thereto included in the Company's annual
report on Form 10-K for the year ended December 31, 1996. The accounting
policies employed are the same as those shown in Note A to the Consolidated
Financial Statements on Form 10-K.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note A - Statement of Financial Accounting Standards (SFAS) No.128,
         Earnings per Share

         In February 1997 the Financial Accounting Standards Board issued SFAS
No.128, Earnings per Share. This statement is effective for financial
statements issued for periods ending after December 15, 1997, including interim
periods; earlier adoption is not permitted. This statement will require
restatement for all prior-period earnings per share (EPS) data presented.
         SFAS No.128 simplifies the standards for computing EPS previously
found in APB Opinion No.15, Earnings per Share, and makes them comparable to
international EPS standards. It replaces the presentation of primary EPS with
the presentation of basic EPS. It also requires dual presentation of basic and
diluted EPS on the face of the income statement for all entities with complex
capital structures and requires a reconciliation of the numerator and
denominator of the basic EPS computation to the diluted EPS computation.
         Basic EPS excludes dilution and is computed by dividing income
available to common shareholders by the weighted-average number of common
shares outstanding for the period. Diluted EPS reflects the potential dilution
that could occur if securities or other contracts to issue common stock were
exercised or converted into common stock or resulted in the issuance of common
stock that then shared in the earnings of the entity. Diluted EPS is computed
similarly to fully diluted EPS pursuant to Opinion 15.
         EPS as calculated under Opinion 15, and as shown on the consolidated
condensed statement of income contained herein, and in the following
Management's Discussion and Analysis, for the nine-month periods ended
September 30, 1997 and September 30, 1996 was $2.25 and $1.98, respectively.
The restated basic EPS amounts for those same periods in 1997 and 1996, had
SFAS No.128 been in effect, would have been $2.27 and $1.99, respectively. The
restated diluted EPS amounts for those same periods in 1997 and 1996, had SFAS
No.128 been in effect, would have been $2.25 and $1.98, respectively.

NET INTEREST INCOME / MARGIN.

         The Company's net interest margin decreased 16 basis points from the
third quarter of 1996 to 3.89% for the 1997 third quarter period. This decrease
is reflective of the increase in the ratio of interest-bearing funds to earning
assets. This ratio was 90% at September 30, 1997, up from the September 30,
1996 ratio of 88%. Further, the quarter over quarter trend was affected by the
loan mix. The Company is continuing to place emphasis on growing its commercial
loan portfolio. These loans are very competitively priced in the marketplace,
generally having thinner margins than other lending opportunities. However,
these loans have shorter maturities than other loan types, reducing the
Company's exposure to interest rate, credit, and liquidity risk. See Table 2
for detailed information concerning quarterly average volumes, interest, yields
earned and rates paid.

PROVISION FOR LOAN LOSSES.

         The provision for loan losses for the third quarter of 1997 was $20.0
million, reflecting a decrease of $1.9 million from the 1996 third quarter
level of $21.9 million. The slight decrease in the third quarter provision
reflects the low level of net charge-offs, and slower loan growth during the
third quarter. On a year-to-date basis the provision for loan losses was $68.9
million, reflecting an increase of $6.1 million or 9.6% from the first nine
months of 1996. Net charge-offs for the quarter were $9.9 million, bringing the
total for the year to $34.8 million. Total net charge-offs of loans on an
annualized basis amounted to .18% of average net loans for the 1997 third
quarter and .23% for the nine month period compared to .24% for the third
quarter of 1996 and .29% for the first nine months of 1996. For the year ended
December 31, 1996 net charge-offs were $47.6 million or .28% of net loans.

NON-INTEREST INCOME.

         Total non-interest income for the quarter ended September 30, 1997 was
$69.8 million, an increase of $9.3 million or 15.3% over the same period in
1996. For the nine month period ended September 30, 1997, non-interest income
was up 5.5% from the comparable period in 1996 to $195.8 million. Service
charges on deposit accounts, which represent the largest portion of
non-interest income, increased in the third quarter and the first nine months
of 1997 by 13.7% and 18.6%, respectively, from the comparable year-ago periods
reflecting the overall growth in the number of deposit accounts through both
internal growth and acquisitions. There were no significant non-recurring
non-interest income items recorded in 1996 or 1997.

NON-INTEREST EXPENSE.

         Total non-interest expense increased 14.0% and 16.4% in the third
quarter and first nine months of 1997 as compared to the same periods in 1996.
These increases are reflective of the overall growth the Company has
experienced over the past year. Salaries and employee benefits expense is the
largest component of non-interest expense, accounting for $105.2 million or 55%
of all non-interest expense for the quarter ended September 30, 1997. The
September 30, 1997 quarter over September 30, 1996 increase in salary and
employee benefits expense was $23.2 million or 28.4%, due mainly to the
increase in the number of full time equivalent employees, which increased 13.6%
over the same period to approximately 10,000. During the third quarter of 1996
the Company amended certain employee benefit arrangements which resulted in the
defeasance of liabilities and a reduction in employee benefits expense totaling
$5.1 million. On a year-to-date basis salaries and benefits expense was $298.1
million for 1997, up $56.5 million or 23.4% over the comparable period in 1996.
Occupancy and equipment expenses were also up in the 1997 third quarter. Both
of these items are affected by the number of banking offices which increased by
5% from the December 31, 1996 level to over 530 at September 30, 1997.
         The efficiency ratio, a measure of non-interest expense to net
interest income plus non-interest income, was 56.36% for the nine month period
ended September 30, 1997, down from the year ago ratio of 57.21%.
         On September 30, 1996, legislation was passed that required a one-time
assessment on deposits insured by the Savings Association Insurance Fund. This
assessment, which amounted to approximately $14.0 million, reduced after-tax
earnings by $8.6 million. There were no other significant non-recurring
non-interest expense items recorded in 1996 or 1997.

INCOME TAX EXPENSE.

         Income tax expense for the third quarter of 1997 was $44.1 million for
an effective tax rate of 36.0% compared to $29.1 million or an effective rate
of 30.7% in the third quarter of 1996. The 1996 third quarter effective tax
rate was lower than the 1997 rate primarily due to the reversal of
approximately $4.5 million of accrued tax that will not be paid as a result of
legislation enacted during the 1996 third quarter which rescinded a previous
law requiring the recapture of certain bad debt deductions previously deducted
by Thrift institutions upon their conversion from a Thrift charter to a bank
charter. For the nine months ended September 30, 1997 income tax expense was
$125.4 million for an effective tax rate of 35.8% compared to tax expense of
$94.7 million and an effective rate of 33.7% during the first nine months of
1996. The statutory federal income tax rate was 35% in 1997 and 1996.

LOANS.

         Loans, net of unearned income at September 30, 1997 were $21,667.8
million, an increase of $2,336.7 million or 12.1% over the December 31, 1996
level. Of the total loan increase, $421.5 million was obtained in the
acquisitions of other financial institutions consummated during the first nine
months of 1997. Internal growth accounted for the remaining $1,915.2 million of
the increase.
         Management made a strategic decision to reduce the amount of indirect
lending and to closely manage the required return expected on various loan
product types. This decision contributed to lower loan growth in the third
quarter of 1997.
         The Company has participated in the loan securitization process
through both on and off balance sheet transactions. These transactions allow
the company to actively manage its loan portfolio. Specifically, the off
balance sheet securitizations provide a vehicle to originate loans and earn
fees on loans while maintaining credit concentrations at levels within the
Company's desired goals.

ALLOWANCE FOR LOAN LOSSES.

         The Company maintains an allowance for loan losses to absorb possible
losses inherent in the loan portfolio. While deterioration of the economy or
rising interest rates could have a near-term effect on the Company's earnings,
Management has taken into consideration present and expected economic
conditions, the level of risk in the portfolio, the level of non-performing
assets, potential problem loans, and delinquencies in assessing the allowance
for loan losses and considers the allowance for loan losses to be adequate. As
asset quality and economic conditions change, the allowance for loan losses
will be increased or decreased accordingly.

         The allowance for loan losses at September 30, 1997 was $310.7 million
or 1.43% of net loans compared to $269.9 million or 1.40% at December 31, 1996.
Net charge-offs during the quarter and nine months ended September 30, 1997
totaled $9.9 million and $34.8 million or 0.18% and 0.23%, respectively, of
average net loans on an annualized basis. The provision for loan losses during
these same periods added $20.0 million and $68.9 million, respectively, to the
allowance for loan losses. The allowance for loan losses at acquisition date of
acquired financial institutions totaled $6.8 million for 1997.

Non-Performing Assets.

         Non-performing assets, which include non-accrual and restructured
loans, other real estate and other repossessed assets were $175.9 million at
September 30, 1997, an increase of $36.9 million over the December 31, 1996
level. Non-performing assets obtained through acquisitions during the
nine-month period totaled $7.8 million. This increase is the result of a
largely diversified group of credits having different credit risk
characteristics, geographic distributions and underlying collateral
characteristics. As evidenced by the relatively flat levels of the quarterly
comparison of the non-performing asset to loan ratios shown below, the increase
is more closely tied to the continuing increase in size of the Company's loan
portfolio, rather than the result of trends in economic conditions that are
likely to affect overall credit quality or loan charge-offs over the
foreseeable future. The ratio of non-performing assets to total loans plus
other real estate owned was 81 basis points at September 30, 1997, while the
allowance for loan losses to non-performing loans ratio was 268.38% for the
same period.
         As of September 30, 1997, the Company had loans of approximately $24.6
million for which management has serious doubts as to the ability of the
borrowers to comply with the present repayment terms, which may result in the
loans' repayment terms being restructured and/or the loans going on
non-performing status. These loans are current with respect to principal and
interest payments and are not presently on non-accrual status; however, they
are continuously reviewed by management and their classification may be changed
if conditions warrant.

HELD-TO-MATURITY AND AVAILABLE-FOR-SALE SECURITIES.

         The investment portfolio is managed to maximize yield over an entire
interest rate cycle while providing liquidity and minimizing risk. Securities
classified as held-to-maturity are carried at amortized cost, as the Company
has the ability and positive intent to hold these securities to maturity. All
securities not considered held-to-maturity or part of the trading portfolio
have been designated as available-for-sale and are carried at fair value.
Unrealized gains and losses on securities available-for-sale are excluded from
earnings and are reported net of deferred taxes as a component of stockholder's
equity. This caption includes securities that Management intends to use as part
of its asset / liability management strategy or that may be sold in response to
changes in interest rates, changes in prepayment risk, liquidity needs, or for
other purposes.
         The Company's investment in collateralized mortgage obligations
present some degree of risk that the mortgages collateralizing the securities
can repay, thereby affecting the yield of the securities and their carrying
amounts. Such an occurrence is most likely in periods of declining interest
rates when many borrowers refinance their mortgages, creating prepayments on
their existing mortgages.
         The Company's investment in structured notes and other derivative
investment securities is nominal and would not have a significant effect on the
Company's net interest margin.

SHORT-TERM INVESTMENTS.

         Short-term investments at September 30, 1997 totaled $461.7 million,
reflecting an increase of $236.2 million from the December 31, 1996 level of
$225.5 million. At September 30, 1997, short-term investments consisted of $72.1
million in federal funds sold and security repurchase agreements, $19.6 million
in time deposits with other banks, $333.7 million in mortgage loans in the
process of being securitized and sold to third party investors and $36.3 million
in securities held for trading purposes. Mortgage loans held for sale are
carried at the lower of cost or fair value. Trading account securities are
carried at fair value with unrealized gains and losses recognized in net income.
         The Company's Asset/Liability Management Committee monitors current and
future expected economic conditions, as well as the Company's liquidity position
in determining desired balances of short-term investments and alternative uses
of such funds.

FUNDING.

         The Company's funding sources can be divided into four broad
categories: deposits, short-term borrowings, Federal Home Loan Bank (FHLB)
advances, and long-term debt.
         Deposits are the Company's primary source of funding. Total deposits
at September 30, 1997 were $19,010.9 million up $1,705.4 million or 9.9% from
the December 31, 1996 level of $17,305.5 million. During the first nine months
of 1997, acquisitions of other financial institutions added $1,387.5 million of
deposits. At September 30, 1997, total deposits included interest-bearing
deposits of $16,890.2 million and other deposits of $2,120.7 million. Core
deposits, defined as demand deposits and time deposits less than $100,000,
totaled $16,345.1 million or 86.0% of total deposits at September 30, 1997.
This compares to core deposits of $14,954.3 million or 86.4% at December 31,
1996.
         Short-term borrowings at September 30, 1997 were $4,779.1 million and
included federal funds purchased of $2,233.9 million, securities sold under
agreements to repurchase of $1,399.4 million and other borrowed funds of
$1,145.8 million. At September 30, 1997, total short-term borrowings were 16.1%
of total liabilities and stockholders' equity. This compares to total
short-term borrowings of $4,071.0 million or 15.5% of total liabilities and
stockholders' equity at December 31, 1996.
         FHLB advances totaled $2,532.4 million at September 30, 1997. The
current quarter end balance is up $788.2 million or 45% from level outstanding
at December 31, 1996. The Company uses FHLB advances as an alternative to
increasing its liability in certificates of deposits or other deposit programs
with similar maturities. These advances generally offer more attractive rates
when compared to other mid-term financing options. They are also flexible,
allowing the Company to quickly obtain the necessary maturities and rates that
best suit its overall asset / liability strategy.
         At September 30, 1997, total long-term debt was $981.9 million,
representing a decrease of $1.3 million, resulting from repayments, from the
December 31, 1996 level of $983.2 million. The Company issued no additional
long-term debt during the first nine months of 1997. Acquisitions completed
during the first nine months had no effect on long-term debt outstanding.

CAPITAL.

         The Company is subject to various regulatory capital requirements that
prescribe quantitative measures of the Company's assets, liabilities, and
certain off-balance sheet items. The Company's regulators have also imposed
qualitative guidelines for capital amounts and classifications such as risk
weighting, capital components, and other details. The quantitative measures to
ensure capital adequacy require that the Company maintain Tier 1 and Total
capital to risk-weighted assets of 4% and 8%, respectively, and Tier 1 capital
to average total assets of 4%. Failure to meet minimum capital requirements can
initiate certain actions by regulators that, if undertaken could have a direct
material effect on the Company's financial statements. As of the periods ended
below the Company meets all capital adequacy requirements imposed by its
regulators.

COMMITMENTS.

         The Company's subsidiary bank had standby letters of credit
outstanding of approximately $605.6 million at September 30, 1997 and $595.1
million at December 31, 1996.
         The Company's subsidiary bank had outstanding commitments to extend
credit of approximately $6,748.3 million at September 30, 1997 and $6,319.9
million at December 31, 1996.
         The Company's policies as to collateral and assumption of credit risk
for off-balance sheet commitments are essentially the same as those for
extension of credit to its customers.
         Presently the Company has no commitments for significant capital
expenditures.

<PAGE>   22

         The Company's subsidiaries regularly originate and sell loans,
consisting primarily of mortgage loans sold to third party investors, which
contain various recourse provisions to the seller. Losses historically realized
through the repurchase or other satisfaction of these recourse provisions have
been insignificant. The total amount of loans outstanding subject to recourse
was $1,152.3 million at September 30, 1997 and $1,163.6 million at December 31,
1996. Under terms of the recourse agreements, the Company would be required to
repurchase certain loans if they become non-performing. All such loans sold had
a loan-to-collateral ratio of 80% or less, or mortgage insurance to cover
losses up to 80% of the collateral value, at the times the various loans were
originated. The underlying collateral to these mortgages are generally 1-4
family residential properties. Potential losses under these recourse agreements
are affected by the collateral value of the particular loans involved. Losses
are recognized when the mortgage is repurchased or the obligation is otherwise
satisfied.

INTEREST RATE RISK MANAGEMENT.

         SouthTrust's asset/liability management strategies are designed to
optimize net interest income while minimizing fluctuations caused by changes in
the interest rate environment. To achieve this, the Company uses various
modeling techniques to simulate interest rate risks associated with different
repricing dates, yield curve changes, basis risk and option risk. Important
elements of these modeling techniques include the mix of floating versus fixed
rate assets and liabilities, and the scheduled, as well as expected, repricing
and maturing volumes and rates of the existing balance sheet.
         In conjunction with the Company's asset/liability management
strategies, the Company utilizes interest rate swap agreements ("Swaps") to
hedge certain longer-term debt and deposit liabilities, converting the
effective rate paid on the hedged liabilities to a floating rate from a fixed
rate. All Swaps employed by the Company represent end-user activities designed
as hedges and, accordingly, fluctuations in the fair values of such contracts
are not included in the results of operations.

CONTINGENCIES.

         Certain of the Company's subsidiaries are defendants in various legal
proceedings arising in the normal course of business. These claims relate to
the lending and investment advisory services provided by the Company and
include alleged compensatory and punitive damages.
         In addition, subsidiaries of the Company have been named as defendants
in suits that allege fraudulent, deceptive or collusive practices in connection
with certain financing activities. These suits are typical of complaints that
have been filed in recent years challenging financial transactions between
plaintiffs and various financial institutions. The complaints in such cases
frequently seek punitive damages in transactions involving fairly small amounts
of actual damages, and in recent years, have resulted in large punitive damage
awards to plaintiffs.
         Although it is not possible to determine, with any certainty, the
potential exposure related to punitive damages in connection with these suits,
Management, based upon consultation with legal counsel, believes that the
ultimate resolutions of these proceedings will not have a material adverse
effect on the Company's financial statements.

RECENT DEVELOPMENTS.

         Effective June 2, 1997, the Corporation, pursuant to the Reigle-Neal
Interstate Banking and Branching Efficiency Act of 1994 (the "Reigle-Neal
Act"), consolidated all of its banking subsidiaries, consisting of ten banking
subsidiaries located in the states of Alabama, Florida, Georgia, North
Carolina, Mississippi, Tennessee and South Carolina, into its largest banking
subsidiary, SouthTrust Bank of Alabama, National Association and changed the
name of the combined institution to SouthTrust Bank, N.A. The bank
consolidation was undertaken by the Corporation in order to obtain the benefits
of the Reigle-Neal Act, which, subject to certain limitations, permits, after
June 1, 1997, qualifying bank holding companies to engage in interstate mergers
and allows banks to maintain and operate branches in states other than the
states where they maintain their principal place of business.
         On September 11, 1997 the Company filed with the Securities and
Exchange Commission a shelf registration statement on Form S-3 registering up
to $300,000,000 of Debt securities, Preferred stock, and/or Common Stock. The
Company's previous registration statement, which also provided for the issuance
of up to $300,000,000 of Debt securities, Preferred Stock and/or Common Stock,
expired September 12, 1997.
         Pursuant to the provisions of the September 11, 1997 S-3, on October
9, 1997, the Company issued 2,500,000 shares of Common Stock at $51.00 per
share, less an underwriting discount of $1.65 per share. The Company intends to
use the net proceeds from the sale primarily for general corporate and working
capital purposes, including funding investments in, or extensions of credit to,
its banking and non-banking subsidiaries. Also, depending on market conditions,
the type of acquisition opportunities presented to the Company and other
factors, some portion of the net proceeds may be used to fund the acquisition
of other financial institutions.
         The Company has completed acquisitions of four financial institutions
since January 1, 1997. These acquisitions added approximately $1,463.3 million
in assets, $421.5 million in loans, and $1,387.5 million in deposits. In the
normal course of business, the Company seeks out and receives inquiries from
financial institutions regarding the possible acquisition of such institutions.
The Company routinely evaluates these opportunities. Currently, the Company is
under two definitive agreements with other financial institutions. The first is
for the sale of the Tuskegee and Ashland,

                                       23

<PAGE>   24

Alabama branches of the Company's subsidiary bank SouthTrust Bank, N.A., to
First National Bank of Ashland. The sale of these branches, which have total
assets of approximately $26.8 million, is scheduled to close in the fourth
quarter of 1997. The second agreement is for the purchase of First of America
Bank-Florida, FSB, a subsidiary of Barnett Banks, Inc., and is scheduled for a
first quarter 1998 closing date. This acquisition will add approximately $1.1
billion in assets to the Company.
