                                 LSB CORPORATION
                           SECOND QUARTER RESULTS 2004

NORTH ANDOVER, MA, -- (BUSINESS WIRE) - July 16, 2004 - LSB Corporation, (the
"Corporation" or the "Company") (NASDAQ-LSBX), today announced results for the
three and six months ended June 30, 2004. Press releases and SEC filings can be
viewed on the internet at our website www.LawrenceSavings.com/press-main.asp or
www.LawrenceSavings.com/stockholder-info.asp, respectively.

The Corporation reported net income of $2,357,000 or $0.53 diluted earnings per
share for the second quarter of 2004. This amount compares to net income of
$635,000 or $0.15 diluted earnings per share for the same period of 2003. Net
income for the six months ended June 30, 2004 totaled $3,143,000 or $0.71
diluted earnings per share compared to $1,185,000 or $0.27 diluted earnings per
share for the six months ended June 30, 2003.

Net income for the three months and six months ended June 30, 2004 increased
$1,722,000 and $1,958,000, respectively due primarily to the receipt of
$2,528,000 on a U.S. Bankruptcy Judge's Order on the Trustee's Motion for
authorization to make an interim distribution in a case in which the Company's
wholly owned subsidiary, Lawrence Savings Bank (the "Bank"), is a secured
creditor. The Bank recognized $253,000 of the interim distribution as a recovery
to the allowance for loan losses on amounts previously charged off and the
remaining $2,275,000 as a lawsuit judgment collected in non-interest income. The
amount of the interim distribution has not previously been recognized in the
Company's Consolidated Financial Statements. The diluted earnings per share
impact of the interim distribution is approximately $0.35 per share based on
average dilutive shares outstanding at June 30, 2004. The Bank recorded a
negative provision for loan losses of $300,000 for the quarter ended June 30,
2004.

Net income for the three months ended June 30, 2004 increased, aside from the
lawsuit judgment collected noted above, due to revenue increases of which net
interest income increased by $368,000 and non-interest income increased by
$122,000. This was offset by non-interest expenses increasing by $399,000. The
increase of $944,000 in the provision for income taxes is primarily attributed
to the lawsuit judgment recovery. Net income for the six months ended June 30,
2004 increased by $1,958,000 due mainly to the receipt of the $2,275,000 lawsuit
judgment collected. Net interest income and non-interest income increased by
$528,000 and $164,000, respectively. Partially offsetting these revenues was an
increase in non-interest expenses of $215,000 and the provision for income taxes
increased by $1,094,000 primarily attributable to the recovery mentioned above.

Net interest income for the quarter ended June 30, 2004, increased by $368,000
or 12.3% to $3,366,000 compared to the same period in 2003. Net interest income
for the six months ended June 30, 2004 increased by $528,000 or 8.4% to
$6,789,000 from $6,261,000 in 2003. Interest expense was affected by lower
interest rates on deposits and borrowed funds, combined with a shift in the mix
of deposits and borrowed funds to lower interest rate products. The net interest
margin for the first six months of 2004, compared to the first six months of
2003, decreased slightly to 2.94% from 3.00%.

The increase in non-interest income of $122,000 for the second quarter of 2004
from $383,000 in the same quarter of 2003 was primarily due to loan fee income
increasing to $123,000 in 2004 compared to loan fee loss of $50,000 in 2003. The
increase in loan fees for the second quarter of 2004 can be attributed to an
increase of $55,000 in prepayment penalties on commercial real estate loan
payoffs and to an increase in fair value on mortgage servicing rights ("MSR")
for which $52,000 was a decrease to the valuation allowance in 2004 compared to
provision for losses in fair value of $72,000 in the second quarter of 2003. The
reason for higher provisions for losses on MSR in 2003 is due to higher than
normal prepayment speeds used in the fair value calculation of MSR experienced
by the Company in 2003 compared to 2004. Deposit account fees increased in 2004
to $230,000 versus $180,000 in 2003 due to an increase in NOW account fees of
$41,000 attributable to a new service the Company offered in 2004 not offered in
2003. Partially offsetting these increases was a decrease in gains on sales of
mortgage loans declining to $58,000 from $165,000 in the second quarter of 2004
and 2003. Non-interest income increased to $827,000 from $663,000 in the first
six month of 2004 and 2003, respectively, primarily attributable to increases in
loan fee income to $143,000 from loan fee loss of $180,000 and deposit account
fees increasing to $432,000 from $343,000 in the first six months of 2004 from
2003, respectively. Partially offsetting these increases was a decrease in gains
on loan sales to $69,000 in 2004 from $314,000 in the first six months of 2003
due to a lower level of loan sales.

Non-interest expenses were $2,771,000 in the second quarter of 2004 compared to
$2,372,000 for the same quarter of 2003. The increase in the second quarter of
2004 is primarily due to salaries and employee benefits rising to $1,627,000 in
2004 from $1,420,000 in 2003 due to normal salary increases and the addition to
headcount for the new Salem, New Hampshire branch. Professional fees increased
to $216,000 from $162,000 in the second quarter of 2004 compared to 2003
primarily due to higher legal expenses associated with the lawsuit judgment
collection and consulting expenses. Data processing increased to $232,000 from
$179,000 in the second quarter of 2004 attributable to increased service bureau
charges. Occupancy and equipment increased to $242,000 from $202,000 due to
higher depreciation expense in the second quarter of 2004. Other expenses
increased to $454,000 from $409,000 mainly due to an increase in marketing
expenses relating to the new Salem, New Hampshire branch. Non-interest expenses
totaled $5,259,000 for the first six months of 2004 compared to $5,044,000 in
the first six months of 2003. This increase was mainly attributable to salaries
and benefits increasing to $3,249,000 from $3,071,000 in the first six months of
2004 from 2003, respectively, also contributing to the increase was data
processing expense of $72,000 in 2004 due to the increased service bureau
charges.

The Corporation continues to look for quality assets, seeks to maintain a low
level of risk assets and seeks to grow the loan portfolio profitably. This is
evident by the low level of delinquencies and non-performing loans as of June
30, 2004 and December 31, 2003. Non-performing loans totaled $106,000 and zero
at June 30, 2004 and December 31, 2003, respectively. The Company booked a
negative provision for loan losses in the amount of $300,000 in the second
quarter of 2004 due to the $253,000 recovery to the allowance for loan loss and
the continued low level of non-performing loans and made no provision for loan
losses in 2003. The coverage of the allowance for loan losses to total loans has
decreased slightly to 1.96% at June 30, 2004 from 2.00% at December 31, 2003.

Total assets increased to $476,274,000 at June 30, 2004 up from $466,108,000 at
December 31, 2003. The increase in asset size at June 30, 2004 from December 31,
2003 is mainly attributable

to an increase of $6,558,000 in investment securities, $2,656,000 in Federal
funds sold and $1,101,000 in Federal Home Loan Bank stock. The funding for these
assets came from an increase in deposits of $17,184,000. Deposit growth was also
used to paydown borrowed funds of $8,032,000 as they became due during 2004.

Total deposits at June 30, 2004 were $289,724,000 up from $272,540,000 at
December 31, 2003. The change from December 31, 2003 is due primarily to
increases in certificates of deposit, money market investment, and NOW accounts.
All other deposit categories experienced slight increases. The overall mix of
deposits has changed from higher interest bearing deposits to lower interest
bearing accounts during the second quarter of 2004.

At June 30, 2004, the Company's stockholders' equity was $56,976,000 as compared
to $55,002,000 at December 31, 2003. The increase during 2004 occurred due to
net income of $3,143,000 and proceeds from the exercise of stock options of
$361,000. Offsetting these increases were the declaration of cash dividends to
shareholders of $1,112,000 and a decrease in the market values of securities
available for sale (net of taxes) of $418,000 The Corporation's leverage ratio
was 11.63% and 12.11% at June 30, 2004 and December 31, 2003, respectively. The
Corporation exceeds all regulatory minimum capital ratio requirements as defined
by the Federal Reserve Bank as of and for all periods presented. The Bank
exceeds all regulatory minimum capital ratio requirements as defined by the FDIC
as of and for all periods presented.
