                                 LSB CORPORATION
                           FIRST QUARTER RESULTS 2004

NORTH ANDOVER, MA, -- (BUSINESS WIRE) - April 16, 2004 - LSB Corporation, (the
"Corporation" or the "Company") (NASDAQ-LSBX), today announced results for the
first quarter ended March 31, 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 $786,000 or $0.18 diluted earnings per
share for the first quarter of 2004. This amount compares to net income of
$550,000 or $0.13 diluted earnings per share for the same period of 2003. Net
income for the quarter ended March 31, 2004 increased 43% primarily attributable
to a rise in net interest income of $160,000, non-interest income increasing by
$42,000 and a reduction in non-interest expenses of $184,000.

Net interest income for the quarter ended March 31, 2004, increased $160,000
compared to the same period in 2003. Net interest income increased by 4.9% to
$3,423,000 for the first quarter 2004 compared to $3,263,000 in 2003. Interest
income during the first quarter of 2004 experienced an overall decrease due to a
lower interest rate environment on interest earning assets and lower average
balances of loans offset by higher average balances of investment securities as
compared to 2003. Interest expense was affected by lower interest rates on
deposits and borrowed funds, combined with a shift in the mix for deposits and
borrowed funds to lower interest rate products. As a result, the net interest
margin decreased slightly in 2004 to 3.02% from 3.15% in 2003.

The increase in non-interest income of $42,000 for the first quarter of 2004
from $280,000 in the same quarter of 2003 was primarily due to an increase in
loan fee income to $20,000 in 2004 compared to loan fee loss of $130,000 in
2003. The increase in loan fees for the first quarter of 2004 can be attributed
to a reduction in provisions for losses on mortgage servicing rights ("MSR") to
$19,000 in 2004 compared to $229,000 in the first 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
$202,000 versus $163,000 in 2003 due to an increase in NOW account fees of
$32,000 attributable to a new product the Company offered in 2004 not offered
until December 2003. Partially offsetting these increases was a decrease in
gains on sales of mortgage loans declining to $11,000 from $149,000 in the first
quarter of 2004 and 2003, respectively, due to a reduction in loan sales by
$5,490,000.

Non-interest expenses were $2,488,000 in the first quarter of 2004 compared to
$2,672,000 for the same quarter of 2003. This decrease in the first quarter of
2004 is primarily due to a

reduction in professional fees to $115,000 from $201,000 in the first quarter of
2003 resulting from lower legal and consulting expenses. Salaries and employee
benefits declined to $1,622,000 in 2004 from $1,651,000 in 2003 due to a lower
headcount. Other expenses totaled $349,000 in the first quarter of 2004 down
from $413,000 in 2003's first quarter. Other expenses decreased due in part to
$100,000 of legal expenses which were reimbursed as part of an insurance claim
recovery in the amount of $197,000. Offsetting this decrease were increases in
other operating expenses, marketing and customer servicing expenses totaling
$36,000 in the aggregate.

The Corporation continues to look for quality assets and seeks to maintain a low
level of risk assets and to grow the loan portfolio profitably. This is evident
by the low level of delinquencies and non-performing loans as of March 31, 2004
and December 31, 2003. Non-performing loans totaled $106,000 and zero at March
31, 2004 and December 31, 2003, respectively. The Company made no provision for
loan losses in 2004 and 2003. The coverage of the allowance for loan losses to
total loans has decreased to 1.93% at March 31, 2004 from 2.00% at December 31,
2003 attributable to higher loan balances.

Total assets increased to $482,029,000 at March 31, 2004 up from $466,108,000 at
December 31, 2003. The increase in asset size at March 31, 2004 from December
31, 2003 is mainly attributable to an increase of $7,087,000 in loans and
$7,556,000 in investment securities and Federal funds sold, respectively. The
funding for these assets came from an increase in deposits of $8,346,000 and
borrowed funds of $7,459,000 since December 31, 2003.

Total deposits at March 31, 2004 were $280,886,000 up from $272,540,000 at
December 31, 2003. The change from December 31, 2003 is due primarily to
increases in money market investment accounts, demand deposit accounts and
savings accounts. The mix of deposits has changed from higher interest bearing
deposits to lower interest bearing accounts during the first quarter of 2004.

At March 31, 2004, the Company's stockholder's equity was $55,629,000 as
compared to $55,002,000 at December 31, 2003. The increase during 2004 occurred
due to net income of $786,000, the exercise of stock options of $300,000 and an
increase in market values on securities available for sale (net of taxes) by
$94,000. The declaration of dividends to shareholders decreased stockholders'
equity by $553,000. The Corporation's leverage ratio was 11.52% and 12.11% at
March 31, 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.
