ITEM 1. BUSINESS

General

  AmSouth Bancorporation (AmSouth) is a bank holding company, which was
organized in 1970 as a corporation under the laws of Delaware and commenced
doing business in 1972. At December 31, 1999, AmSouth had total consolidated
assets of approximately $43.4 billion. AmSouth offers a broad range of bank
and bank-related services through its subsidiaries. AmSouth's principal
subsidiary is AmSouth Bank (the Bank).

  The Bank is a banking corporation organized under the laws of the State of
Alabama and is a wholly owned subsidiary of AmSouth. As of December 31, 1999,
the Bank had total consolidated assets of approximately $43.2 billion and
total consolidated deposits of approximately $27.9 billion. As of December 31,
1999, the assets of the Bank constituted virtually all of the assets of
AmSouth.

  In October 1999, AmSouth acquired First American Corporation (First
American), a bank holding company headquartered in Nashville, Tennessee, and
caused First American to be merged into AmSouth in a transaction accounted for
as a pooling-of-interests. As of September 30, 1999, First American had total
consolidated assets of $22.2 billion and total deposits of $14.5 billion. For
more information regarding the acquisition of First American, see
"Management's Discussion and Analysis of Financial Condition and Results of
Operations", which is incorporated herein by reference pursuant to Item 7 of
this Form 10-K, and the "Notes to Consolidated Financial Statements", which
are incorporated herein by reference pursuant to Item 8 of this Form 10-K.

  AmSouth has three reportable segments: Consumer Banking, Commercial Banking
and Capital Management. Consumer Banking delivers a full range of financial
services to individuals and small businesses. Services include loan products
such as residential mortgages, equity lending, credit cards, and loans for
automobile and other personal financing needs, and various products designed
to meet the credit needs of small businesses. In addition, Consumer Banking
offers various deposit products that meet customers' savings and transaction
needs. Commercial Banking meets corporate and middle market customers' needs
with a comprehensive array of credit, treasury management, international, and
capital markets services. Included among these are several specialty services
such as real estate finance, asset based lending, commercial leasing, and
healthcare banking. Capital Management is comprised of client fiduciary
services and broker/dealer services, and provides primarily fee based income.
This area includes not only traditional trust services, but also a substantial
selection of investment management services including AmSouth's proprietary
mutual fund family. The services and products of all three of AmSouth's
segments are offered to businesses and individuals through approximately 640
banking offices located in Alabama, Florida, Tennessee, Mississippi,
Louisiana, Arkansas, Kentucky, Virginia and Georgia. In addition to its
banking offices, the Bank operates a network of over 1,340 automated teller
machines that are linked with shared automated tellers in all 50 states.
Further segment information is included in Note 22 of Notes to Consolidated
Financial Statements, which is incorporated herein by reference pursuant to
Item 8, of this Form 10-K.

  As of February 29, 2000, AmSouth and its subsidiaries had 13,882 employees.

Competition

  AmSouth's subsidiaries compete aggressively with banks located in Alabama,
Florida, Tennessee, Mississippi, Louisiana, Arkansas, Kentucky, Virginia and
Georgia, as well as large banks in major financial centers, and with other
financial institutions, such as savings and loan associations, credit unions,
consumer finance companies, brokerage firms, insurance companies, investment
companies, mortgage companies, and financial service operations of major
retailers. Competition is based on a number of factors, including prices,
interest rates, services, and availability of products. AmSouth also competes
with other bank holding companies headquartered in the United States and
abroad for the acquisition of financial institutions. At December 31, 1999,
AmSouth was the 19th largest bank holding company headquartered in the United
States in terms of total assets.

  Various regulatory developments and existing laws have allowed financial
institutions to conduct significant activities on an interstate basis for a
number of years. During recent years, a number of financial institutions

                                       3
<PAGE>

expanded their out-of-state activities, and various states enacted legislation
intended to allow certain interstate banking combinations which otherwise
would have been prohibited by federal law. For a number of years, the Bank
Holding Company Act of 1956, as amended (the BHCA), generally provided that no
company which owned or controlled a commercial bank in the United States could
acquire ownership or control of a commercial bank in a state other than the
state in which the company's banking subsidiaries were principally located
unless the acquisition was specifically authorized by the laws of the state in
which the bank being acquired was located.

  The Riegle-Neal Interstate Banking and Branching Efficiency Act of 1994 (the
IBBEA) authorized interstate acquisitions of banks and bank holding companies
without geographic limitation beginning September 29, 1995. In addition,
beginning June 1, 1997, the IBBEA authorizes a bank to merge with a bank in
another state as long as neither of the states has opted out of interstate
branching by May 31, 1997. A bank may establish and operate a de novo branch
in a state in which the bank does not maintain a branch if that state
expressly permits de novo branching. Once a bank has established branches in a
state through an interstate merger transaction, the bank may establish and
acquire additional branches at any location in the state where any bank
involved in the interstate merger transaction could have established or
acquired branches under applicable federal or state law. A bank that has
established a branch in a state through de novo branching may establish and
acquire additional branches in such state in the same manner and to the same
extent as a bank having a branch in such state as a result of an interstate
merger. If a state opted out of interstate branching within the specified time
period, no bank in any other state may establish a branch in the opting out
state, whether through an acquisition or de novo. None of the states in which
AmSouth had subsidiary banks on June 1, 1997 "opted out" of the provisions of
the IBBEA permitting interstate branching by acquisition. Although the
management of AmSouth cannot predict with certainty the full effect of the
IBBEA on AmSouth, management believes the IBBEA resulted in greater
consolidation within the banking industry and such consolidation is likely to
continue.

The Gramm-Leach-Bliley Act

  In November 1999, President Clinton signed into law the Gramm-Leach-Bliley
Act. The Gramm-Leach-Bliley Act significantly revises the laws regulating
banks and bank holding companies and other providers of financial services.
The Gramm-Leach-Bliley Act (i) repeals the restrictions, formerly contained in
the Glass-Steagall Act, on banks affiliating with securities firms, (ii)
permits a company to form a "financial holding company," which may own insured
depository institutions and engage through non-bank affiliates in a broader
range of financial activities than previously had been allowed, including
underwriting securities, insurance underwriting, merchant banking and
insurance company investments, so long as the depository institution
subsidiaries are well capitalized, well managed and receive at least a
satisfactory Community Reinvestment Act rating on their most recent
examination, (iii) permits the Board of Governors of the Federal Reserve
System (Federal Reserve Board) and the Department of the Treasury to determine
that other activities are also permissible for financial holding companies,
(iv) provides that the Federal Reserve will be responsible for "umbrella"
supervision and examination of financial holding companies, and that other
federal and state regulators will regulate, supervise and examine
"functionally regulated subsidiaries" such as insurance companies and broker-
dealers, (v) allows national banks that meet certain requirements to engage in
new financial activities (other than insurance underwriting, merchant banking,
insurance company investments and real estate development) in subsidiaries of
such banks, and (vi) establishes certain restrictions on the transfer and use
by financial institutions of nonpublic personal information of their
customers. The enactment of the Gramm-Leach-Bliley Act is expected to
intensify competition in, and the consolidation of, the financial services
industry. However, the management of AmSouth cannot currently predict the full
impact of the enactment of the Gramm-Leach-Bliley Act on AmSouth.

Business Combinations

  AmSouth continually evaluates business combination opportunities and
sometimes conducts due diligence activities in connection with them. As a
result, business combination discussions and, in some cases, negotiations

                                       4
<PAGE>

take place, and transactions involving cash, debt or equity securities can be
expected. Any future business combination or series of business combinations
that AmSouth might undertake may be material, in terms of assets acquired or
liabilities assumed, to AmSouth's financial condition. Recent business
combinations in the banking industry have typically involved the payment of a
premium over book and market values. This practice may result in dilution of
book value and net income per share for the acquirers.

Supervision and Regulation

  The following discussion addresses the regulatory framework applicable to
bank holding companies and their subsidiaries, and provides certain specific
information relevant to AmSouth. Regulation of financial institutions such as
AmSouth and its subsidiaries is intended primarily for the protection of
depositors, the deposit insurance funds of the Federal Deposit Insurance
Corporation (the FDIC) and the banking system as a whole, and generally is not
intended for the protection of stockholders or other investors.

  The following is a summary of certain statutes and regulations that apply to
the operation of banking institutions. Changes in the applicable laws, and in
their application by regulatory agencies, cannot necessarily be predicted, but
they may have a material effect on the business and results of banking
organizations, including AmSouth.

 General

  As a bank holding company, AmSouth is subject to the regulation and
supervision of the Federal Reserve Board under the BHCA. Historically, under
the BHCA, bank holding companies could not, in general, directly or indirectly
acquire the ownership or control of more than 5 percent of the voting shares
or substantially all of the assets of any company, including a bank, without
the prior approval of the Federal Reserve Board. In addition, bank holding
companies were generally prohibited under the BHCA from engaging in nonbanking
activities, subject to certain exceptions. The activities permissible for bank
holding companies were significantly expanded by the Gramm-Leach-Bliley Act. For
a summary of its provisions, see "The Gramm-Leach-Bliley Act" above. AmSouth
cannot predict at this time to what extent, if any, it will engage in any of
these expanded activities.

  The Bank is a state bank, chartered under the laws of Alabama, and is a
member of the Federal Reserve System. It is generally subject to regulation
and supervision by both the Federal Reserve Board and the Office of the
Superintendent of Banking of the State of Alabama. The Bank is also an insured
depository institution, and, therefore, also subject to regulation by the
FDIC. The Bank is also subject to various requirements and restrictions under
federal and state law, including requirements to maintain reserves against
deposits, restrictions on the types and amounts of loans that may be granted
and the interest that may be charged thereon, and limitations on the types of
investments that may be made and the types of services that may be offered.
Various consumer laws and regulations also affect the operations of the Bank.
In addition to the impact of regulation, commercial banks are affected
significantly by the actions of the Federal Reserve Board as it attempts to
control the money supply and credit availability in order to influence the
economy.

 Payment of Dividends

  AmSouth is a legal entity separate and distinct from its banking and other
subsidiaries. The principal source of cash flow for AmSouth, including cash
flow to pay dividends on AmSouth's capital stock and to pay interest and
principal on any debt of AmSouth, is dividends from the Bank. There are
statutory and regulatory limitations on the payment of dividends by the Bank
to AmSouth as well as by AmSouth to its shareholders. The payment of dividends
by AmSouth and the Bank also may be affected by other factors, such as the
requirement to maintain capital at or above regulatory guidelines. See
"Capital Adequacy and Related Matters" below.

  Under Alabama law, a bank may not pay a dividend in excess of 90 percent of
its net earnings until the bank's surplus is equal to at least 20 percent of
capital. The Bank is also required by Alabama law to obtain the prior approval
of the Superintendent of the State Banking Department of Alabama for the
payment of dividends

                                       5
<PAGE>

if the total of all dividends declared by the Bank in any calendar year will
exceed the total of (a) the Bank's net earnings (as defined by statute) for
that year plus (b) its retained net earnings for the preceding two years, less
any required transfers to surplus. Also, no dividends may be paid from the
Bank's surplus without the prior written approval of the Superintendent.

  In addition, as a member of the Federal Reserve System, the Bank is required
by federal law to obtain regulatory approval for the payment of dividends if
the total of all dividends declared by the Board of Directors of such bank in
any year could exceed the total of (a) the Bank's net income (as reportable in
its Reports of Condition and Income) for that year, plus (b) the Bank's
retained net income (as defined and interpreted by regulation) for the
preceding two years, less any net losses incurred in the current or prior two
years and any required transfers to surplus or a fund for the retirement of
preferred stock.

  Furthermore, if, in the opinion of the applicable federal bank regulatory
authority, a bank under its jurisdiction is engaged in or is about to engage
in an unsafe or unsound practice (which, depending on the financial condition
of the bank, could include the payment of dividends), such authority may
require, after notice and a hearing, that such bank cease and desist from such
practice. The Federal Reserve Board has indicated that paying dividends that
deplete a bank's capital base to an inadequate level would be an unsafe and
unsound banking practice. In addition, the Federal Deposit Insurance Act (the
FDI Act) imposes additional restrictions on the payments of dividends by the
Bank, as described under "Capital Adequacy and Related Matters-Prompt
Corrective Action" below. Moreover, the Federal Reserve Board has issued a
policy statement that provides that bank holding companies and state member
banks should generally pay dividends only out of current operating earnings.

  Under dividend restrictions imposed under federal and Alabama law, including
those described above, the Bank, without obtaining government approvals, could
declare aggregate dividends in 2000 of approximately $227.2 million, plus an
additional amount equal to its net income for 2000.

 Capital Adequacy and Related Matters

 Capital Guidelines

  The Federal Reserve Board has adopted risk-based capital guidelines for bank
holding companies. The minimum guideline for the ratio of total regulatory
capital (Total Capital) to risk-weighted assets (including certain off-
balance-sheet items, such as standby letters of credit) is 8 percent. At least
half of the Total Capital must be composed of common stockholders' equity,
retained earnings, minority interests in the equity accounts of consolidated
subsidiaries, noncumulative perpetual preferred stock, and a limited amount of
qualifying cumulative perpetual preferred stock, less goodwill and certain
other intangible assets (Tier 1 Capital). The remainder may consist of
subordinated debt, other preferred stock and a limited amount of loan loss
reserves. At December 31, 1999, AmSouth's consolidated Tier 1 Capital and
Total Capital ratios were 7.46 percent and 10.66 percent, respectively.

  In addition, the Federal Reserve Board has established minimum leverage
ratio guidelines for bank holding companies. The guidelines provide for a
minimum ratio of Tier 1 Capital to average assets, less goodwill and certain
other intangible assets (the Leverage Ratio), of 3 percent for bank holding
companies that meet certain specific criteria, including having the highest
regulatory rating. All other bank holding companies generally are required to
maintain a Leverage Ratio of at least 3 percent, plus an additional cushion of
100 to 200 basis points. AmSouth's Leverage Ratio at December 31, 1999 was
6.22 percent. The guidelines also provide that bank holding companies
experiencing internal growth or making acquisitions will be expected to
maintain strong capital positions substantially above the minimum supervisory
levels without significant reliance on intangible assets. Furthermore, the
Federal Reserve Board has indicated that it will consider a "Tangible Tier 1
Capital Leverage Ratio" (deducting all intangibles) and other indicators of
capital strength in evaluating proposals for expansion or new activities.

                                       6
<PAGE>

  The Bank is also subject to risk-based and leverage capital requirements,
similar to those described above. The Bank complied with applicable minimum
capital requirements as of December 31, 1999. Neither AmSouth nor the Bank has
been advised by any federal banking agency of any specific minimum Leverage
Ratio requirement applicable to it.

  The Federal Reserve Board has adopted modifications to the Tier 1 Capital
and Total Capital ratios applicable to both banks and bank holding companies
that are intended to address "market risk" arising from large trading
portfolios. These modifications are applicable only to banks and bank holding
companies whose trading activities exceed certain thresholds, and to those
that voluntarily comply with the market risk capital requirement. AmSouth is
not subject to, nor has voluntarily adopted, these new requirements.

  Bank regulators have the authority generally to raise capital requirements
applicable to banking organizations beyond their current levels. However, the
management of AmSouth is unable to predict whether and when higher capital
requirements would be imposed, and, if so, at what levels and on what
schedule.

 Prompt Corrective Action

  The FDI Act requires the federal banking regulators to take prompt
corrective action in respect of FDIC-insured depository institutions that do
not meet minimum capital requirements. The FDI Act establishes five capital
tiers: "well capitalized," "adequately capitalized," "undercapitalized,"
"significantly undercapitalized," and "critically undercapitalized." Under
applicable regulations, a state member bank is defined to be well capitalized
if it maintains a Leverage Ratio of at least 5 percent, a risk-adjusted Tier 1
Capital Ratio of at least 6 percent, and a Total Capital Ratio of at least 10
percent and is not subject to any order or written directive to maintain any
specific capital level. A state member bank is defined to be adequately
capitalized if it maintains a Leverage Ratio of at least 4 percent, a risk-
adjusted Tier 1 Capital Ratio of at least 4 percent, and a Total Capital Ratio
of at least 8 percent. In addition, a state member bank will be considered:
(a) undercapitalized if it fails to meet any minimum required measure; (b)
significantly undercapitalized if it is significantly below such measure; and
(c) critically undercapitalized if it fails to maintain a level of tangible
equity equal to not less than 2 percent of total assets. A state member bank
may be deemed to be in a capitalization category that is lower than is
indicated by its actual capital position if it is operating in an unsafe or
unsound manner or receives an unsatisfactory examination rating. AmSouth
believes that at December 31, 1999, the Bank had capital ratios sufficient to
qualify as "well capitalized".

  The capital-based prompt corrective action provisions of the FDI Act and the
implementing regulations apply to FDIC-insured depository institutions such as
the Bank, and are not directly applicable to holding companies, like AmSouth,
that control such institutions. However, the Federal Reserve Board has
indicated that, in regulating bank holding companies, it will take appropriate
action at the holding company level based on an assessment of the
effectiveness of supervisory actions imposed upon subsidiary depository
institutions pursuant to such provisions and regulations. Although the capital
categories defined under the prompt corrective action regulations are not
directly applicable to AmSouth under existing law and regulations, if AmSouth
were placed in a capital category it would qualify as well-capitalized as of
December 31, 1999.

  The FDI Act generally prohibits an FDIC-insured depository institution from
making any capital distribution (including payment of dividends) or paying any
management fee to its holding company if the depository institution would
thereafter be undercapitalized. Undercapitalized insured depository
institutions are subject to restrictions on borrowing from the Federal Reserve
System. In addition, undercapitalized depository institutions are subject to
growth limitations and are required to submit capital restoration plans. An
insured depository institution's holding company must guarantee the capital
plan, up to an amount equal to the lesser of 5 percent of the depository
institution's assets at the time it becomes undercapitalized or the amount of
the capital deficiency when the institution fails to comply with the plan. The
federal banking agencies may not accept a capital plan without determining,
among other things, that the plan is based on realistic assumptions and is
likely to succeed in restoring the depository institution's capital. If an
insured depository institution fails to submit an acceptable plan, it is
treated as if it is significantly undercapitalized.

                                       7
<PAGE>

  Significantly undercapitalized insured depository institutions may be
subject to a number of requirements and restrictions, including orders to sell
sufficient voting stock to become adequately capitalized, requirements to
reduce total assets and cessation of receipt of deposits from correspondent
banks. Critically undercapitalized insured depository institutions are subject
to appointment of a receiver or conservator.

 Brokered Deposits and Pass-Through Insurance

  The FDIC has adopted regulations under the FDI Act governing the receipt of
brokered deposits. Under the regulations, an FDIC-insured depository
institution cannot accept, roll over or renew brokered deposits unless (a) it
is well capitalized or (b) it is adequately capitalized and receives a waiver
from the FDIC. A depository institution that cannot receive brokered deposits
also cannot offer "pass-through" insurance on certain employee benefit
accounts. Whether or not it has obtained such a waiver, an adequately
capitalized depository institution may not pay an interest rate on any
deposits in excess of 75 basis points over certain prevailing market rates
specified by regulation. There are no such restrictions on a depository
institution that is well capitalized. Because the Bank was well capitalized as
of December 31, 1999, AmSouth believes the brokered deposits regulation will
have no material effect on the funding or liquidity of the Bank.

 Holding Company Structure

  There are various legal restrictions on the extent to which AmSouth and its
nonbank subsidiaries may borrow or otherwise obtain funding from the Bank. The
Bank (and its subsidiaries) is limited in engaging in borrowing and other
"covered transactions" with nonbank and nonsavings bank affiliates to the
following amounts: (a) in the case of any single such affiliate, the aggregate
amount of covered transactions of the Bank and its subsidiaries may not exceed
10 percent of the capital stock and surplus of the Bank; and (b) in the case
of all affiliates, the aggregate amount of covered transactions of the Bank
and its subsidiaries may not exceed 20 percent of the capital stock and
surplus of the Bank. Covered transactions also are subject to certain
collateralization requirements. "Covered transactions" are defined by statute
to include a loan or extension of credit, as well as a purchase of securities
issued by an affiliate, a purchase of assets (unless otherwise exempted by the
Federal Reserve Board) from the affiliate, the acceptance of securities issued
by the affiliate as collateral for a loan, and the issuance of a guarantee,
acceptance, or letter of credit on behalf of an affiliate.

  Under Federal Reserve Board policy, AmSouth is expected to act as a source
of financial strength to, and to commit resources to support, the Bank. This
support may be required at times when, absent such Federal Reserve Board
policy, AmSouth may not be inclined to provide it. In addition, any capital
loans by a bank holding company to a subsidiary bank are subordinate in right
of payment to deposits and to certain other indebtedness of such subsidiary
bank. In the event of a bank holding company's bankruptcy, any commitment by
the bank holding company to a federal bank regulatory agency to maintain the
capital of a subsidiary bank will be assumed by the bankruptcy trustee and
entitled to a priority of payment.

  The FDI Act provides that, in the event of the "liquidation or other
resolution" of an insured depository institution, the claims of depositors of
such institution (including claims by the FDIC as subrogee of insured
depositors) and certain claims for administrative expenses of the FDIC as
receiver would be afforded a priority over other general unsecured claims
against the institution including any claims of the bank's holding company as
a creditor. If an insured depository institution fails, insured and uninsured
depositors, along with the FDIC, will be placed ahead of unsecured, nondeposit
creditors, including a parent holding company such as AmSouth, in its capacity
as creditor, in order of priority of payment.

 FDIC Deposit Insurance Assessments

  The Bank is subject to FDIC deposit insurance assessments pursuant to two
separate assessment schedules, one applicable to those deposits insured by the
Bank Insurance Fund (BIF) and another applicable to those deposits insured by
the Savings Association Insurance Fund (SAIF).


                                       8
<PAGE>

  The FDIC's current risk-based system places a bank in one of nine risk
categories, principally on the basis of its capital level and an evaluation of
the bank's risk to the fund, and bases premiums on the probability of loss to
the FDIC with respect to each individual bank. Currently, the FDIC's risk-
based system provides that the highest and lowest annual assessments per $100
of deposits insured by the BIF or SAIF are $.27 and $0. The assessment rate
schedule is subject to change by the FDIC and accordingly assessment rates
could increase in the future. The Bank's total FDIC assessments were $5.4
million pretax in 1999.

 Liability for Affiliate Insured Depository Institutions

  Under the FDI Act, an insured depository institution, such as the Bank, can
be held liable for any loss incurred by, or reasonably expected to be incurred
by, the FDIC in connection with (a) the default of a commonly controlled FDIC-
insured depository institution or (b) any assistance provided by the FDIC to
any commonly controlled FDIC-insured depository institution "in danger of
default." "Default" is defined generally as the appointment of a conservator
or receiver and "in danger of default" is defined generally as the existence
of certain conditions indicating that a default is likely to occur in the
absence of regulatory assistance. AmSouth currently has only one small
depository institution subsidiary other than the Bank, but that subsidiary
will be merged into the Bank on March 31, 2000. It is possible, however, that
AmSouth will have other depository institution subsidiaries in the future.

ITEM 2. PROPERTIES

  The executive offices of AmSouth are located in the AmSouth-Sonat Tower in
downtown Birmingham, Alabama. An undivided one-half interest in this building
is owned by the Bank through an unincorporated joint venture. The Bank is a
principal tenant of this building. The Bank is also a principal tenant of
other multi-story office buildings in Birmingham, Alabama and Nashville,
Tennessee. The Bank also has other banking and operational offices located in
its nine-state market area.

  At December 31, 1999, AmSouth and its subsidiaries had 774 offices
(principally bank buildings) of which 513 were owned and 261 were either
leased or subject to a ground lease.

ITEM 3. LEGAL PROCEEDINGS

  Several of AmSouth's subsidiaries are defendants in legal proceedings
arising in the ordinary course of business. Some of these proceedings seek
relief or damages that are substantial. The actions relate to AmSouth's
lending, collections, loan servicing, deposit taking, investment, trust and
other activities.

  Among the actions which are pending against AmSouth subsidiaries are actions
filed as class actions. The actions are similar to others that have been
brought in recent years against financial institutions in that they seek
punitive damage awards in transactions involving relatively small amounts of
actual damages. Legislation was recently enacted in Alabama that is designed
to limit the potential amount of punitive damages that can be recovered in
individual cases in the future. However, AmSouth cannot predict the exact
effect of the legislation at this time.

  It may take a number of years to finally resolve some of these legal
proceedings pending against AmSouth subsidiaries, due to their complexity and
for other reasons. It is not possible to determine with any certainty at this
time the corporation's potential exposure from the proceedings. At times,
class actions are settled by defendants without admission or even an actual
finding of any wrongdoing but with payment of some compensation to purported
class members and large attorney's fees to plaintiff class counsel.
Nonetheless, based upon the advice of legal counsel, AmSouth's management is
of the opinion that the ultimate resolution of these legal proceedings will
not have a material adverse effect on AmSouth's financial condition or results
of operations.

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

  There were no matters brought to a vote of security holders during the
fourth quarter of 1999.

for the years ended December 31, 1998 and 1997 is included herein as follows:

                         Independent Auditors' Report

The Board of Directors
AmSouth Bancorporation:

  We have audited the consolidated balance sheets of First American
Corporation and subsidiaries as of December 31, 1998 and 1997, and the related
consolidated income statements, changes in shareholders' equity, and cash
flows for each of the years then ended. These financial statements are the
responsibility of the Company's management. Our responsibility is to express
an opinion on these financial statements based on our audit.

  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

  In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of First
American Corporation and subsidiaries as of December 31, 1998 and 1997, and
the results of its operations and its cash flows for the years then ended in
conformity with generally accepted accounting principles.
