The registrant's voting stock is not regularly and actively traded in any
established market, and there are no regularly quoted bid and asked prices for
the registrant's common stock. Based upon recent negotiated trading of the
common stock at a price of $135 per share, the registrant believes that the
aggregate market value of the voting stock on March 24, 1999 was $183.3 million.
For purposes of this calculation, it is assumed that directors, officers and
beneficial owners of more than 5% of the registrant's outstanding voting stock
are not affiliates. On such date, 1,357,948 shares of the common stock were
issued and outstanding.

</TABLE>

      Commercial Loans. The Company's principal lending activities include the
origination of commercial loans in the Company's primary lending area.
Commercial loans are made for a variety of business purposes, including working
capital, inventory and equipment and capital expansion. At December 31, 1998,
commercial loans outstanding totaled $121.3 million, or 26.0% of the Company's
total net loan portfolio. The terms for commercial loans are generally one to
seven years. Commercial loan applications must be supported by current financial
information on the borrower and, where appropriate, by adequate collateral.
Commercial loans are generally underwritten by addressing cash flow (debt
service coverage), primary and secondary sources of repayment, financial
strength of any guarantor, liquidity, leverage, management experience, ownership
structure, economic conditions and industry-specific trends and collateral. The
loan to value ratio depends on the type of collateral. Generally speaking,
accounts receivable are financed at 60% of accounts receivable less than 90 days
past due. If other collateral is taken to support the loan, the loan to value of
accounts receivable may approach 85%. Inventory financing will range between 25%
and 60% depending on the borrower and nature of inventory. The Company requires
a first lien position for such loans. These types of loans are generally
considered to be a higher credit risk than other loans originated by the
Company.

      Commercial Real Estate Loans. The Company originates commercial loans,
generally to existing business customers, secured by real estate located in the
Company's market area. At December 31, 1998, commercial real estate loans
totaled $115.2 million, or 24.7% of the Company's total net loan portfolio. The
terms of such loans are generally for ten to twenty years and are priced based
in part upon the prime rate, as reported in The Wall Street Journal. Commercial
real estate loans are generally underwritten by addressing cash flow (debt
service coverage), primary and secondary source of repayment, financial strength
of any guarantor, strength of the tenant (if any), liquidity, leverage,
management experience, ownership structure, economic conditions and industry
specific trends and collateral. Generally, the Company will loan up to 85% of
the value of improved property, 65% of the value of raw land and 75% of the
value of undeveloped land. A first lien on the property and assignment of lease
is required if the collateral is rental property, with second lien positions
considered on a case by case basis.

      Mortgage Installment Loans. The Company also originates one-to-four
family, owner-occupied residential mortgage loans secured by property located in
the Company's primary market area. The majority of the Company's residential
mortgage loans consists of loans secured by owner-occupied, single-family
residences. At December 31, 1998, the Company had $153.2 million, or 32.8% of
its total net loan portfolio, in mortgage installment loans. The Company also
originates, to a limited extent, installment real estate loans for other types
of real estate acquisitions. Mortgage installment and installment real estate
loans generally have a loan to value ratio of 85%. These loans are underwritten
by giving consideration to the ability to pay, stability of employment or source
of income, credit history and loan to value ratio.

      Mortgage loans originated by the Bank are not underwritten in conformity
with secondary market guidelines and therefore are not readily salable. The
Company has not previously engaged in sales of its loans in the secondary
market. Beginning in April 1997, the Company began selling one-to-four family
mortgage loans in the secondary market to Freddie Mac through the Bank's
mortgage banking subsidiary, Superior Mortgage. Sales of such loans totaled
$41.0 million during 1998, and the related mortgage servicing rights were sold
together with the loan.

      Installment Consumer Loans. At December 31, 1998, the Company's
installment consumer loan portfolio totaled $80.1 million, or 17.2% of the
Company's total net loan portfolio. The Company's consumer loan portfolio is
comprised of secured and unsecured loans originated both by the Bank and
Superior Financial. The consumer

                                       3
<PAGE>   5

loans of the Bank generally have a higher risk of default than other loans
originated by the Bank. Further, consumer loans originated by Superior
Financial, a finance company rather than a bank, generally have a greater risk
of default than such loans originated by commercial banks and accordingly carry
a higher interest rate. The performance of consumer loans will be affected by
the local and regional economy as well as the rates of personal bankruptcies,
job loss, divorce and other individual-specific characteristics.

      Past Due, Special Mention, Classified and Non-Accrual Loans. The Company
classifies its problem loans into four categories: past due loans, special
mention loans, classified loans (which are still accruing interest) and
non-accrual loans.

      When management determines that a loan no longer satisfies the criteria
for performing loans and that collection of interest appears doubtful, the loan
is placed on non-accrual status. All loans that are 90 days past due are
considered non-accrual, unless they are adequately secured and there is
reasonable assurance of full collection of principal and interest. Management
closely monitors all loans that are contractually 90 days past due, treated as
"special mention" or otherwise classified or on non-accrual status. Non-accrual
loans that are 120 days past due without assurance of repayment are charged off
against the allowance for loan losses.

      The following table sets forth information with respect to the Company's
non-performing assets at the dates indicated. At these dates, the Company did
not have any restructured loans within the meaning of Statement of Financial
Accounting Standards No. 15.

</TABLE>

      Non-accrual loans increased $1.9 million, or 82.6%, from $2.3 million at
December 31, 1997 to $4.2 million at December 31, 1998. The increase is
principally comprised of a group of four commercial loans totaling $1.8 million,
all of which are fully secured by real estate located within the primary
business area of the Bank. Of these four loans, two were performing as of March
1999. In addition, the increase in non-accrual loans reflects management's
efforts during 1998 to more aggressively review and monitor past due loans.
During 1998, the Company recorded a $3.4 million charge to income through its
provision for loan losses to reflect anticipated losses arising from these
loans.

      The Company's continuing efforts to resolve non-performing loans
occasionally includes foreclosures, which result in the Company's ownership of
the real estate underlying the mortgage. If non-accrual loans at December 31,
1998 had been current according to their original terms and had been outstanding
throughout 1998, or since origination if originated during the year, interest
income on these loans would have been approximately $260,600. Interest actually
recognized on these loans during 1998 was not significant.

      The increase in real estate owned during 1998 from $508,000 at December
31, 1997 to $1,527,000 at December 31, 1998 primarily reflects management's
implementation of a more aggressive collection strategy, which includes
foreclosing on loans past due 120 days without providing borrowers with a
delaying option to restructure. The $920,000 in foreclosed real estate consists
of eight properties, of which property valued at $200,000 was sold for full
value as of March 1999. Management expects that the remaining foreclosed real
estate can be sold at an amount sufficient to recover the remaining $720,000.

      At December 31, 1998, the Company had approximately $3.0 million in loans
that are not currently classified as non-accrual or 90 days past due or
otherwise restructured and where known information about possible credit
problems of borrowers caused management to have serious concerns as to the
ability of the borrowers to comply with present loan repayment terms. Such loans
were considered classified by the Company and comprised various commercial and
commercial real estate loans, including one commercial loan for $1.6 million
secured by a blanket lien on the land, plant and equipment of the business as
well as significant additional collateral. Management believes the value of the
collateral is presently sufficient to cover the full amount of the loan, plus
accrued interest. This loan was considered classified based upon cash flows of
the business deemed insufficient to cover debt service. For further information,
see Note 1 of Notes to Consolidated Financial Statements.

      Allowance for Loan Losses. The allowance for loan losses is maintained at
a level which management believes is adequate to absorb all potential losses on
loans then present in the loan portfolio. The amount of the allowance is
affected by: (1) loan charge-offs, which decrease the allowance; (2) recoveries
on loans previously charged-off, which increase the allowance; and (3) the
provision of possible loan losses charged to income, which increases the
allowance. In determining the provision for possible loan losses, it is
necessary for management to monitor fluctuations in the allowance resulting from
actual charge-offs and recoveries, and to periodically review the size and
composition of the loan portfolio in light of current and anticipated economic
conditions in an effort to evaluate portfolio risks. If actual losses exceed the
amount of the allowance for loan losses, earnings of the Company could be
adversely affected. The amount of the provision is based on management's
judgment of those risks and therefore the allowance represents general, rather
than specific, reserves. During the year ended December 31, 1998, the Company's
provision for loan losses decreased by $2.5 million to $3.4 million to reflect
the reduction in actual or potential losses arising from the loan portfolio. For
additional information, see Note 1 of Notes to Consolidated Financial
Statements.

DEPOSITS

      Deposits are the primary source of funds for the Company. Such deposits
consist of checking accounts, regular savings deposits, NOW accounts, Money
Market Accounts and market rate Certificates of Deposit. Deposits are attracted
from individuals, partnerships and corporations in the Company's market area. In
addition, the Company obtains deposits from state and local entities and, to a
lesser extent, U.S. Government and other depository institutions. The Company's
policy permits the acceptance of limited amounts of brokered deposits, but no
such deposits had been obtained as of or during the year ended December 31,
1998.

      The following table sets forth the average balances and average interest
rates based on daily balances for deposits for the periods indicated.

COMPETITION

      To compete effectively, the Company relies substantially on local
commercial activity; personal contacts by its directors, officers, other
employees and shareholders; personalized services; and its reputation in the
communities it serves.

      According to data as of June 30, 1998 supplied by the FDIC, the Bank
ranked as the largest independent commercial bank in its market area, which
includes Greene, Hamblen, Washington, Blount and McMinn Counties and portions of
Cocke, Hawkins, Jefferson and Knox Counties. In Greene County, there are six
commercial banks and one savings bank, operating 23 branches and holding an
aggregate of approximately $696 million in deposits as of June 30, 1998.

      Under the federal Bank Holding Company Act of 1956 (the "Holding Company
Act"), as amended by the Riegle-Neal Interstate Banking and Branching Efficiency
Act of 1994 (the "Riegle-Neal Act"), Tennessee banks and their holding companies
may be acquired by out-of-state banks or their holding companies, and Tennessee
banks and their holding companies may acquire out-of-state banks without regard
to whether the transaction is prohibited by the laws of any state. In addition,
the federal banking agencies may approve interstate merger transactions without
regard to whether such transactions are prohibited by the law of any state,
unless the home state of one of the banks opts out of the Riegle-Neal Act by
adopting a law that applies equally to all out-of-state banks and expressly
prohibits merger transactions involving out-of-state banks. The effect of the
Riegle-Neal Act may be to increase competition within the State of Tennessee
among banking institutions located in Tennessee and from banking companies
located anywhere in the country.

EMPLOYEES

      As of December 31, 1998, the Company employed 307 persons. None of the
Company's employees are presently represented by a union or covered under a
collective bargaining agreement. Management of the Company considers relations
with employees to be good.

REGULATION, SUPERVISION AND GOVERNMENTAL POLICY

      The following is a brief summary of certain statutes, rules and
regulations affecting the Company and the Bank. A number of other statutes and
regulations have an impact on their operations. The following summary of
applicable statutes and regulations does not purport to be complete and is
qualified in its entirety by reference to such statutes and regulations.

      Bank Holding Company Regulation. The Company is registered as a bank
holding company under the Holding Company Act and, as such, subject to
supervision, regulation and examination by the Board of Governors of the Federal
Reserve Board (the "FRB").

      Acquisitions and Mergers. Under the Holding Company Act, a bank holding
company must obtain the prior approval of the FRB before (i) acquiring direct or
indirect ownership or control of any voting shares of any bank or bank holding
company if, after such acquisition, the bank holding company would directly or
indirectly own or control more than 5% of such shares; (2) acquiring all or
substantially all of the assets of another bank or bank holding company; or (3)
merging or consolidating with another bank holding company. Also, any company
must

                                       9
<PAGE>   11

obtain approval of the FRB prior to acquiring control of the Company or the
Bank. For purposes of the Holding Company Act, "control" is defined as ownership
of more than 25% of any class of voting securities of the Company or the Bank,
the ability to control the election of a majority of the directors, or the
exercise of a controlling influence over management or policies of the Company
or the Bank.

      The Holding Company Act, as amended by the Riegle-Neal Act, generally
permits the FRB to approve interstate bank acquisitions by bank holding
companies without regard to any prohibitions of state law. See "Competition".

      The Change in Bank Control Act and the related regulations of the FRB
require any person or persons acting in concert (except for companies required
to make application under the Holding Company Act), to file a written notice
with the FRB before such person or persons may acquire control of the Company or
the Bank. The Change in Bank Control Act defines "control" as the power,
directly or indirectly, to vote 25% or more of any voting securities or to
direct the management or policies of a bank holding company or an insured bank.

      The Holding Company Act also prohibits, with certain exceptions, a bank
holding company from acquiring direct or indirect ownership or control of more
than 5% of the voting shares of a company that is not a bank or a bank holding
company, or from engaging directly or indirectly in activities other than those
of banking, managing or controlling banks, or providing services for its
subsidiaries.

      Capital Requirements.  The Company is also subject to FRB guidelines
that require bank holding companies to maintain specified minimum ratios of
capital to total assets and capital to risk-weighted assets.  See "-- Capital
Requirements."

      Dividends. The FRB has the power to prohibit dividends by bank holding
companies if their actions constitute unsafe or unsound practices. The FRB has
issued a policy statement expressing its view that a bank holding company should
pay cash dividends only to the extent that the company's net income for the past
year is sufficient to cover both the cash dividends and a rate of earning
retention that is consistent with the company's capital needs, asset quality,
and overall financial condition. The Company does not believe this policy
statement will limit the Company's activity to maintain its dividend payment
rate.

      Support of Banking Subsidiaries. Under FRB policy, the Company is expected
to act as a source of financial strength to its banking subsidiaries and, where
required, to commit resources to support each of such subsidiaries. Further, if
the Bank's capital levels were to fall below minimum regulatory guidelines, the
Bank would need to develop a capital plan to increase its capital levels and the
Company would be required to guarantee the Bank's compliance with the capital
plan in order for such plan to be accepted by the federal regulatory authority.

      Under the "cross guarantee" provisions of the Federal Deposit Insurance
Act (the "FDI Act"), any FDIC-insured subsidiary of the Company such as the Bank
could be liable for any loss incurred by, or reasonably expected to be incurred
by, the FDIC in connection with (i) the default of any other FDIC-insured
subsidiary also controlled by the Company or (ii) any assistance provided by the
FDIC to any FDIC-insured subsidiary of the Company in danger of default.

      Transactions with Affiliates. The Federal Reserve Act imposes legal
restrictions on the quality and amount of credit that a bank holding company or
its non bank subsidiaries ("affiliates") may obtain from bank subsidiaries of
the holding company. For instance, these restrictions generally require that any
such extensions of credit by a bank to its affiliates be on nonpreferential
terms and be secured by designated amounts of specified collateral. Further, a
bank's ability to lend to its affiliates is limited to 10% per affiliate (20% in
the aggregate to all affiliates) of the bank's capital and surplus.

      Bank Regulation. As a Tennessee banking institution, the Bank is subject
to regulation, supervision and regular examination by the Banking Department.
The deposits of the Bank are insured by the FDIC to the maximum extent provided
by law (a maximum of $100,000 for each insured depositor). Tennessee and federal
banking laws and regulations control, among other things, required reserves,
investments, loans, mergers and consolidations, issuance of securities, payment
of dividends, and establishment of branches and other aspects of the Bank's
operations. Supervision, regulation and examination of the Company and the Bank
by the bank regulatory

                                       10
<PAGE>   12

agencies are intended primarily for the protection of depositors rather than for
holders of the Common Stock of the Company.

      Extensions of Credit. Under joint regulations of the federal banking
agencies, including the FDIC, banks must adopt and maintain written policies
that establish appropriate limits and standards for extensions of credit that
are secured by liens or interests in real estate or are made for the purpose of
financing permanent improvements to real estate. These policies must establish
loan portfolio diversification standards, prudent underwriting standards,
including loan-to-value limits, that are clear and measurable, loan
administration procedures and documentation, approval and reporting
requirements. A bank's real estate lending policy must reflect consideration of
the Interagency Guidelines for Real Estate Lending Policies (the "Interagency
Guidelines") that have been adopted by the federal bank regulators. The
Interagency Guidelines, among other things, call upon depository institutions to
establish internal loan-to-value limits for real estate loans that are not in
excess of the loan-to-value limits specified in the Guidelines for the various
types of real estate loans. The Interagency Guidelines state that it may be
appropriate in individual cases to originate or purchase loans with
loan-to-value ratios in excess of the supervisory loan-to-value limits. The
aggregate amount of loans in excess of the supervisory loan-to-value limits,
however, should not exceed 100% of total capital and the total of such loans
secured by commercial, agricultural, multifamily and other non-one-to-four
family residential properties should not exceed 30% of total capital.

      Federal Deposit Insurance. The Bank is subject to FDIC deposit insurance
assessments. The FDIC has established a risk-based deposit insurance assessment
system for insured depository institutions, under which insured institutions are
assigned assessment risk classifications based upon capital levels and
supervisory evaluations. Under these regulations, the FDIC set the 1998
insurance assessment rates for BIF-insured banks such as the Bank from zero to
27 basis points.

      Safety and Soundness Standards. The Federal Deposit Insurance Corporation
Improvement Act of 1991 ("FDICIA") required the federal bank regulatory agencies
to prescribe, by regulation, non-capital safety and soundness standards for all
insured depository institutions and depository institution holding companies.
The FDIC and the other federal banking agencies have adopted guidelines
prescribing safety and soundness standards pursuant to FDICIA. The safety and
soundness guidelines establish general standards relating to internal controls
and information systems, internal audit systems, loan documentation, credit
underwriting, interest rate exposure, asset growth, and compensation, fees and
benefits. Among other things, the guidelines require banks to maintain
appropriate systems and practices to identify and manage risks and exposures
identified in the guidelines.

      Capital Requirements. The FRB has established guidelines with respect to
the maintenance of appropriate levels of capital by registered bank holding
companies, and the FDIC has established similar guidelines for state-chartered
banks that are not members of the FRB. The regulations of the FRB and FDIC
impose two sets of capital adequacy requirements: minimum leverage rules, which
require the maintenance of a specified minimum ratio of capital to total assets,
and risk-based capital rules, which require the maintenance of specified minimum
ratios of capital to "risk-weighted" assets. At December 31, 1998, the Company
and the Bank satisfied the minimum required regulatory capital requirements. See
Note 14 of Notes to Consolidated Financial Statements.

      The FDIC has issued final regulations that classify insured depository
institutions by capital levels and require the appropriate federal banking
regulator to take prompt action to resolve the problems of any institution that
fails to satisfy the capital standards. Under such regulations, a
"well-capitalized" bank is one that is not subject to any regulatory order or
directive to meet any specific capital level and that has or exceeds the
following capital levels: a total risk-based capital ratio of 10%, a Tier 1
risk-based capital ratio of 6%, and a leverage ratio of 5%. As of December 31,
1998, the Bank was "well-capitalized" as defined by the regulations. See Note 14
of Notes to Consolidated Financial Statements for further information.
