                                  JUNE 30, 1997

NOTE 1 - BASIS OF PRESENTATION

         The accompanying financial statements have been prepared in accordance
with generally accepted accounting principles for interim financial information
and with the instructions to Form 10-QSB. Accordingly, they do not include all
the information and footnotes required by generally accepted accounting
principles for complete financial statements. In the opinion of management, all
adjustments (consisting of normal recurring accruals) considered necessary for a
fair presentation have been included. Operating results for the six-month period
ended June 30, 1997 are not necessarily indicative of the results that may be
expected for the year ending December 31, 1997. For further information, refer
to the financial statements and footnotes thereto included in Form 10-KSB for
the year ended December 31, 1996.

NOTE 2 - SUMMARY OF ORGANIZATION

         Beach First National Bancshares, Inc., Myrtle Beach, South Carolina
(the "Company"), was incorporated July 28, 1995 under the laws of the State of
South Carolina for the purpose of operating as a bank holding company with
respect to a then proposed de novo bank, Beach First National Bank, Myrtle
Beach, South Carolina (the "Bank").

         The Company offered its common stock for sale to the public under an
initial public offering price of $10 per share. As of December 31, 1996, when
the offering was terminated, 735,868 shares were sold, resulting in net proceeds
of $7,212,349.

         During 1996, the Company obtained regulatory approval to operate a
national bank in Myrtle Beach, South Carolina. The Bank opened for business on
September 23, 1996, with a total capitalization of $6.3 million. Upon the
opening of the Bank, the Company ceased to be considered as a "development stage
enterprise" as its planned principal operations had commenced. The Bank's
deposits are each insured up to $100,000 by the Federal Deposit Insurance
Corporation.


Item 2.           Management's Discussion and Analysis of Financial Condition
                  and Results of Operations

         The following discussion contains forward-looking statements that
involve risks and uncertainties. The Company's actual results may differ
materially from the results discussed in the forward-looking statements, and the
Company's operating performance each quarter is subject to various risks and
uncertainties that are discussed in detail in the Company's filings with the
Securities and Exchange Commission, including the "Risk Factors" section in the
Company's Registration Statement on Form S-1 (Registration Number 33-95562) as
filed with and declared effective by the Securities and Exchange Commission.

         The Company was incorporated July 28, 1995 under the laws of the State
of South Carolina for the purpose of operating as a bank holding company with
respect to the Bank. The Company sold 735,868 shares of its common stock for
$7,212,349, net of expenses. The Company commenced principal operations on
September 23, 1996 when the Bank opened for business.

         Total consolidated assets increased by $7.4 million to $17.4 million
during the six-month period ended June 30, 1997. The increase was generated
primarily through a $7.6 million increase in deposits. The funds were used to
increase loans by $5.0 million, investment securities by $3.0 million, and fixed
assets


                                       -6-
<PAGE>   7
by $899,000. Note that cash and cash equivalents declined by $1.6 million during
this period.

Liquidity and Sources of Capital

         Liquidity is the Company's ability to meet all deposit withdrawals
immediately, while also providing for the credit needs of customers. The June
30, 1997 financial statements evidence a liquidity position, consisting of cash
and cash equivalents, of $1.6 million, representing 9.4% of total assets.
Investment securities amounted to $8.1 million, representing 46.5% of total
assets. These securities provide a secondary source of liquidity since they can
be converted into cash in a timely manner. The Company's ability to maintain and
expand its deposit base and borrowing capabilities also serve as a source of
liquidity. For the six-month period ended June 30, 1997, total deposits
increased from $3.0 million to $10.6 million, representing an annualized
increase of 503.5%. However, this tremendous growth rate is a reflection of the
fact that the Bank just opened for business on September 23, 1996, and the
Company does not expect to maintain or duplicate this growth rate. The Company's
management closely monitors and seeks to maintain appropriate levels of interest
earning assets and interest bearing liabilities so that maturities of assets are
such that adequate funds are provided to meet customer withdrawals and loan
demand. Management expects asset and liability growth to continue at a rapid
pace during the coming months, with the growth tapering off to a slower, more
deliberate and controllable pace over the longer term, and believes capital
should continue to be adequate. However, no assurances can be given in this
regard, as rapid growth, deterioration in loan quality and poor earnings, or a
combination of these factors, could change the Company's capital position in a
relatively short period of time.

         The Bank currently maintains a level of capitalization substantially in
excess of the minimum capital requirements by the Bank's primary regulator, the
OCC.

Results of Operations

         Since principal banking operations only commenced on September 23,
1996, a comparison of the June 30, 1997 results (when banking operations were in
progress) to those of June 30, 1996 are not meaningful. This discussion will
therefore concentrate on the June 30, 1997 results.

         Net loss for the six month period ended June 30, 1997 amounted to
$146,192 or $.20 per share. Net loss for the three month period ended June 30,
1997 amounted to $70,146 or $.10 per share. The following is a brief discussion
of the more significant components of net income:

         Net interest income represents the difference between interest received
on interest earning assets and interest paid on interest bearing liabilities.
The following presents, in a tabular form, the main components of interest
earning assets and interest bearing liabilities.

         Other income for the six month period ended June 30, 1997 amounted to
$12,405. On an annualized basis, this represents .14% of total assets.
Management believes this figure is lower than it will be in future periods
because, in order to attract new banking relationships, the Bank implemented an
initial fee structure and charges that are low when compared to other banks but
which the Bank anticipates will increase in the future.

         Operating expenses for the six month period ended June 30, 1997
amounted to $381,903. On an annualized basis, this represents 4.42% of total
assets.

         At December 31, 1996, the allowance for loan losses amounted to
$16,502. By June 30, 1997, the allowance had grown to $102,002. The allowance
for loan losses, as a percentage of gross loans, grew from 1.50% to 1.66% during
the six month period ended June 30, 1997. The loan portfolio is periodically
reviewed to evaluate the outstanding loans and to measure both the performance
of the portfolio and the adequacy of the allowance for loan losses. This
analysis includes a review of delinquency trends, actual losses, and internal
credit ratings. Management's judgment as to the adequacy of the allowance is
based upon a number of assumptions about future events which it believes to be
reasonable, but which may or may not be reasonable. However, because of the
inherent uncertainty of assumptions made during the evaluation process, there
can be no assurance that loan losses in future periods will not exceed the
allowance for loan losses or that additional allocations to the allowance will
not be required.
