                                 LSB CORPORATION
                           FIRST QUARTER RESULTS 2003

NORTH ANDOVER, MA, -- (BUSINESS WIRE) - April 21, 2003 - LSB Corporation, (the
"Corporation" or the "Company") (NASDAQ-LSBX), today announced results for the
quarter ended March 31, 2003. Go to www.LawrenceSavings.com for all your

The Corporation reported net income of $550,000 or $0.13 diluted earnings per
share for the first quarter of 2003. This amount compares to net income of
$816,000 or $0.18 diluted earnings per share for the same period of 2002.

Net income for the quarter ended March 31, 2003 decreased due to non-interest
income decreasing by $149,000 for the first quarter of 2003 from $429,000 in the
same quarter of 2002. This decrease was primarily due to a decline in loan fees
to a loss of $130,000 in 2003 compared to income of $76,000 in 2002. The loss in
loan fees can be attributed to provisions for losses on mortgage servicing
rights (MSR's) of $229,000 in the first quarter of 2003 due to higher than
normal prepayment speeds used in the fair value calculation of MSR's caused by
the current low interest rate environment on mortgage loans. This loss was
partially offset by an increase in deposit account fees and gains on the sale of
mortgage loans rising by $45,000 in the aggregate for the same periods.
Non-interest expenses were $2,672,000 in the first quarter of 2003 compared to
$2,459,000 for the same quarter of 2002. This increase in the first quarter is
primarily due to salaries and employee benefits increasing to $1,651,000 in 2003
up from $1,537,000 in 2002 due to normal salary increases and increased pension
expense associated with the employees defined benefit pension plan. Professional
expenses increased to $201,000 for the first quarter 2003 from $147,000 for the
same period in 2002 due to increased legal expenses.

Net interest income decreased 2% to $3,263,000 for the first quarter 2003
compared to $3,318,000 in the same quarter in 2002. Interest income in the first
quarter of 2003 experienced an overall decrease due to a declining interest rate
environment on interest earning assets and a change in the asset mix from the
first quarter of 2002. Interest expense incurred a similar decline in interest
rates resulting in lower rates paid on deposits and borrowed funds; however, the
rates paid on borrowed funds have declined at a slower pace than deposit rates.
As a result, the net interest margin decreased slightly in 2003 to 3.15% from
3.19% in 2002.

The Corporation continues to look for quality assets and seeks to maintain a low
level of risk assets as it grows the loan portfolios. Non-performing loans
totaled $23,000 and $1,000 at March 31, 2003 and December 31, 2002,
respectively. The Company has not acquired property through foreclosure in the
past five years.



Total assets decreased to $435,787,000 at March 31, 2003 down from $439,134,000
at December 31, 2002. The decrease in asset size at March 31, 2003 from December
31, 2002 is due to the paydown of $3,012,000 on borrowed funds as these became
due. The cash used came from the payoff of loans which decreased the loan
portfolios by $14,417,000. The additional cash was used to purchase investment
securities and federal funds.

Total deposits at March 31, 2003 were $279,802,000 up from $279,465,000 at
December 31, 2002. The change from December 31, 2002 is due to a decrease in
certificates of deposits and an increase in NOW accounts. Although the total
balance of deposits remained fairly level, the mix of deposits changed from
higher interest bearing deposits to lower interest bearing accounts.

The Corporation's leverage ratio was 12.06% and 12.10% at March 31, 2003 and
December 31, 2002, 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.
