SOUTHERN FINANCIAL BANCORP, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

NOTE 1 - ORGANIZATION AND BASIS OF PRESENTATION

     The accompanying unaudited consolidated financial statements have been
prepared in accordance with the instructions to Form 10-Q, and, therefore, do
not include all information or footnotes necessary for a fair presentation of
financial position, results of operations, and cash flows in conformity with
accounting principles generally accepted in the United States of America.
However, all adjustments which are, in the opinion of management, necessary for
a fair presentation have been included.  All adjustments are of a normal
recurring nature. The results of operations for the three-month period ended
March 31, 2001 are not necessarily indicative of the results of the full year.
These consolidated financial statements should be read in conjunction with the
consolidated financial statements and the notes included in Southern Financial
Bancorp, Inc.'s ("Southern Financial") Annual Report for the year ended December
31, 2000.

     On September 1, 2000, Southern Financial acquired all the outstanding
common stock of First Savings Bank of Virginia for 409,906 shares of Southern
Financial common stock.  The acquisition has been accounted for by the purchase
method of accounting.  At the time of closing, core deposit intangibles were
recorded in the amount of $1,566,163 and are being amortized on a straight-line
basis over 15 years.  The initial excess of the purchase price over the net
identifiable assets acquired of $1,935,954 was recorded as goodwill and is being
amortized on a straight-line basis over 15 years.  During the quarter following
the merger, certain tax adjustments were recorded resulting in an adjusted
goodwill of $1,646,651 before amortization.

     Ownership of Southern WebTech.com was increased to 100% from 70% by
December 31, 2000.  The minority interest was acquired by issuing 7,118 shares
of Southern Financial Bancorp common stock valued at $107,225 to Darien
Consulting Group, Inc., who owned the minority interest.  The purchase method of

NOTE 2 - HEDGE ACCOUNTING

     During the quarter ended March 31, 2001, Southern Financial entered into
interest rate swap agreements totaling $20 million in connection with issuance
of like amounts of its certificates of deposit. These interest rate swap
agreements are accounted for as fair value hedges. Changes in the fair value of
the fair value hedges are accounted for in the income statement, as are changes
in the fair value of the certificates of deposit. Changes in the fair value of
cash flow hedges are accounted for in other comprehensive income. One interest
rate swap agreement with a notional amount of $10 million was terminated during
the quarter ended March 31, 2001 with no resulting gain or loss.  The
certificates of deposit associated with this swap were called by Southern
Financial.  The interest rate swaps outstanding as of March 31, 2001, are
presented in the following table:

NOTE 5 - COMPANY-OBLIGATED MANDATORILY REDEEMABLE SECURITIES OF SUBSIDIARY
         HOLDING SOLELY PARENT DEBENTURES ("TRUST PREFERRED BORROWINGS")

     On December 28, 1999, Southern Financial Capital Trust I, a wholly owned
special purpose subsidiary of the Bancorp, was formed for the purpose of issuing
redeemable capital securities (company-obligated mandatorily redeemable
securities of subsidiary holding solely parent debentures).  On May 24, 2000, a
$5 million offering of redeemable capital securities was completed by the Trust.
The securities have a par value of $5.00, a cash distribution rate of $0.55 per
year, payable quarterly, with a yield of 11% and are due July 15, 2030. The
securities may be called prior to maturity. The proceeds from this issuance were
used to purchase a like amount of junior subordinated debt securities issued by
the Bancorp, which have the same maturity and call provision as the redeemable
capital securities. On September 7, 2000 Southern Financial Statutory Trust I, a
wholly owned special purpose subsidiary of the Bancorp, was formed for the
purpose of issuing additional redeemable capital securities (company-obligated
mandatorily redeemable securities of subsidiary holding solely parent
debentures). Concurrently, $8 million of trust preferred securities were issued
by the Trust as part of a pooled underwriting transaction.  A "pooled
underwriting" involves participating with other bank holding companies in
issuing the securities through a special-purpose pooling vehicle created by the
underwriters.  In this instance the pooling vehicle was Preferred Term
Securities, Ltd., which was underwritten by Keefe Bruyette & Woods and First
Tennessee Capital Markets and placed with investors in a private placement. The
proceeds from this issuance were used to purchase a like amount of junior

          In December 2000, investment securities classified as held-to-maturity
were transferred to the available-for-sale classification in order to provide
more flexibility in managing the interest-rate risk in the investment security
portfolio. Because of the transfer, Southern Financial will be unable to
classify investment securities as held-to-maturity in the foreseeable future.

SOUTHERN FINANCIAL BANCORP, INC.
MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
CONDITION AND RESULTS OF OPERATIONS

Financial Condition
- -------------------

     Total assets of Southern Financial Bancorp, Inc. ("Southern Financial") at
March 31, 2001 were $676.2 million, an increase of 10.9 % compared with December
31, 2000.  The growth in total assets was primarily due to increases in
investment securities available-for-sale and loans receivable.

     Total loans receivable increased 3.8% from $320.4 million at December 31,
2000, with the increase being in nonresidential mortgage and construction loans
and non-mortgage business loans.

     Investment securities available-for-sale increased 20.9 % during the same
period. Southern Financial purchased investment securities totaling $91.4
million during the quarter ended March 31, 2001. The investment securities
purchased consisted of collateralized mortgage obligations and corporate bonds.
During the quarter ended March 31, 2001, Southern Financial sold investment
securities available-for-sale for proceeds totaling $30.4 million.

     The growth in earning assets, as discussed above, was funded by deposits
and borrowings. The increase in advances from the FHLB totaling $21 million
consisted of overnight borrowings. Deposits increased 8.1% from $515.1 million
at December 31, 2000.

Results of Operations
- ---------------------

     Southern Financial's principal sources of revenue are interest on loans,
gains on sales of loans and investment securities, fees and service charges on
loans, interest and dividends on investment securities, and service charges on
deposit accounts.  Net income is affected by interest on deposits and borrowings
and operating expenses.

     The following table presents, for periods indicated, average balances of
and weighted average yields on interest-earning assets and average balances of
and weighted average effective rates paid on interest-bearing liabilities.
Calculations have been made utilizing month-end average balances for loans and
investment securities and daily average balances for borrowings and deposits,
and the effect of the interest rate swaps is reflected in the average rate on
deposits. Loan balances do not include non-accrual loans.

     The following table presents information regarding changes in interest
income and interest expense for the periods indicated.  For each category of
interest-earning assets and interest-bearing liabilities, information is
provided on changes attributable to changes in volume (changes in volume
multiplied by old rate) and changes in rate (changes in rate multiplied by old
volume).  The dollar changes in interest income and interest expense
attributable to changes in rate/volume (change in rate multiplied by change in
volume) have been allocated between rate and volume variances based on the
percentage relationship of such variances to each other.  The effect of the
interest rate swaps is reflected in interest expense on deposits.

     Southern Financial's net income was $1.6 million for the three months ended
March 31, 2001, an increase of 35.9% over the $1.2 million earned during the
quarter ended March 31, 2000.

     Net interest income before provision for loan losses for the three months
ended March 31, 2001 was $5.2 million, an increase of $1 million or 24.7%, from
$4.2 million for the three months ended March 31, 2000  The increase in net
interest income was due to the growth in earning assets resulting from purchases
of investment securities, increased commercial loan originations as well as the
acquisition of $71 million in First Savings Bank's assets.  Average earning
assets increased 51.3% to $583.5 million compared with the first quarter of
2000.

     The provision for loan losses for the three months ended March 31, 2001 was
$520 thousand, as compared to $350 thousand for the three months ended March 31,
2000. The provision for loan losses is a current charge to earnings to increase
the allowance for loan losses.  Southern Financial has established the allowance
for loan losses to absorb the inherent risk in lending after considering an
evaluation of the loan portfolio, current economic conditions, changes in the
nature and volume of lending, past loan experience and other relevant factors.
It is the opinion of Southern Financial that the allowance for loan losses at
March 31, 2001 remains adequate.  Although Southern Financial believes that the
allowance is adequate, there can be no assurances that additions to such
allowance will not be necessary in future periods, which would adversely affect
the results of operations.  The allowance for loan losses at March 31, 2001 was
$5.4 million, or 1.63% of total loans receivable less deferred fees, versus $4.9
million at December 31, 2000, which was 1.54% of total loans receivable less
deferred fees.

     Other income for the three months ended March 31, 2001 was $1.6 million, an
increase from $1.0 for the three months ended March 31, 2000.  During the
quarter ended March 31, 2001, Southern Financial sold $30.4 million of primarily
fixed rate securities and generated net gains of $200 thousand.  In addition,
income totaling $232 thousand representing the increase in the current value of
bank owned life insurance is included in other income.  Other income also
includes the traditional deposit fees, electronic banking fees, and fees
generated from commercial service products, all of which contributed to the
increased non-interest income.

     Other expense for the three months ended March 31, 2001 was $4.0 million,
an increase of 28.6% when compared to other expense for the same period last
year. Increased expenses resulting from the acquisition of First Savings Bank,
including goodwill amortization, accounted for a substantial portion of the
increase. Other expenses, including employee compensation, also increased
primarily due to normal pay increases and a larger employee base.



Regulatory Capital Requirements
- -------------------------------

     At March 31, 2001 Southern Financial exceeded all regulatory capital
standards.

Liquidity
- ---------

     Southern Financial's primary sources of funds are deposits, loan
repayments, proceeds from the sale of loans and investment securities,
repayments and maturities of investment securities, and borrowings from the
Federal Home Loan Bank of Atlanta under a credit availability equal to 20% of
total assets, or approximately $135 million.  At March 31, 2001, Southern
Financial had $37.8 million of unfunded lines of credit and undisbursed
construction loan funds of $22.9 million. Approved loan commitments were $9.9
million at March 31, 2001, and Southern Financial had commitments from investors
to purchase loans in the amount of $1.3 million. It is anticipated that funding
requirements for these commitments can be met from the normal sources of funds.

             On August 29, 2000, a Fauquier County jury returned an unfavorable
             verdict against Southern Financial Bank in a lender liability suit
             filed by a former customer of the Bank. On October 31, 2000, a
             Fauquier County Circuit Court judge set aside the jury verdict and
             ordered that the case be retried. A new trial is scheduled for July
             24, 2001.

             Southern Financial is not a party to, nor is any of their property
             the subject of, any other material pending legal proceedings
             incidental to its business other than those arising in the ordinary
             course of business. Although the amount of any ultimate liability
             with respect to such matters cannot be determined, in the opinion
             of management, any such liability will not have a material adverse
             effect on the consolidated financial position or results of
             operations of Southern Financial.
