      LSB CORPORATION ANNOUNCES SECOND QUARTER 2006 FINANCIAL RESULTS AND
                               QUARTERLY DIVIDEND

NORTH ANDOVER, MA, -- (MARKET WIRE) - July 27, 2006 - LSB Corporation, (the
"Corporation" or the "Company") (NASDAQ-LSBX), today announced a second quarter
2006 net loss of $1.9 million, or $0.42 per diluted share, as compared to net
income of $758,000, or $0.17 per diluted share, for the second quarter of 2005.
In the first six months of 2006 the net loss was $1.7 million, or $0.37 per
diluted share, versus net income of $1.6 million, or $0.36 per diluted share, in
the first six months of 2005. The largest factor in both the quarter and the
year to date results was the previously announced balance sheet restructuring
whereby $80 million of investments were sold at a pre-tax loss of $2.4 million
(after-tax charge of $1.6 million, or $0.35 per diluted share). Other costs
incurred in the second quarter of 2006 were related to the name change of the
Company's subsidiary bank to River Bank and former employee severance payments;
the combination of which totaled approximately $800,000 on a pre-tax basis
(after-tax charge of $525,000, or $0.11 per diluted share).

The Company believes that the most significant challenge in the current interest
rate environment is to increase net interest income while also maintaining
competitive deposit interest rates The Company continued to experience
compression of its net interest margin from 2.70% in the first six months of
2005 to 2.57% in the same period of 2006, for a decline of 13 basis points.
Although the Company expects the balance sheet restructuring to have a positive
impact on its net interest margin in the long-term, much of the restructuring
was not completed until late in the quarter and thus, its effect on the margin
during the quarter ended June 30, 2006 was minimal. In addition, a change in the
timing of the FHLBB (Federal Home Loan Bank of Boston) dividend resulted in no
dividend income on that investment this quarter. The Company expects, however,
that even taking into account the full impact of the balance sheet restructuring
and a normalized FHLBB dividend, deposit and borrowing interest rate increases
will continue to exert downward pressure on its net interest margin.

President Gerald T. Mulligan stated, "I believe that many of the one time
charges incurred this quarter will provide us with an improved competitive
posture and leave us better positioned for any interest rate increases. We are
pleased by the local reception of our name change and are optimistic that our
new name, enhanced marketing, and improved product pricing will lead to
continuing deposit and loan growth. Our increases in all loan categories this
quarter are encouraging."

Total loans increased $13.4 million from December 31, 2005 to $248.0 million as
of June 30, 2006. The increase was in all loan categories and total loans
exceeded total investments for the first time since December 2002. As of June
30, 2006, non-performing loans equaled 0.04% of total loans while the allowance
for loan losses as a proportion of total loans equaled 1.69%.

Total assets decreased $5.9 million from December 31, 2005 to $515.9 million as
of June 30, 2006. The decrease reflected the balance sheet restructuring whereby
a portion of the investment proceeds were used to reduce the Company's reliance
on borrowed funds.

Total deposits increased $1.8 million from December 31, 2005 and totaled $304.9
million as of June 30, 2006. Total borrowed funds decreased during the first six
months of 2006 by $2.5 million or 1.6% and totaled $150.9 million as of June 30,
2006.

The Company also announced a quarterly dividend of $0.14 to be paid on August
24, 2006 to shareholders of record as of August 10, 2006. This dividend
represents a 3.21% annualized dividend yield based on the closing stock price of
$17.44 on June 30, 2006.
