         LSB CORPORATION ANNOUNCES FIRST QUARTER 2006 FINANCIAL RESULTS
                             AND QUARTERLY DIVIDEND

NORTH ANDOVER, MA, -- (MARKET WIRE) -- April 28, 2006 -- LSB Corporation, (the
"Corporation" or the "Company") (NASDAQ-LSBX), today announced first quarter
2006 financial results of $260,000, or $0.06 per diluted share, as compared to
$859,000, or $0.19 per diluted share, for the first quarter of 2005.

The decline in net income for the period ending March 31, 2006 was primarily due
to severance payments in the amount of $373,000 incurred with the resignation of
two former executive officers and to a continued compression of the Company's
net interest margin from 2.78% in the first quarter of 2005 to 2.61% in the
first quarter of 2006.

The most significant challenge the Company faces in the current flattened
interest rate yield curve environment is to increase interest income while also
maintaining competitive deposit interest rates. The Company anticipates that the
squeeze on its net interest margin, which declined by 17 basis points from March
31, 2005 to March 31, 2006, will continue throughout 2006. While the entire
banking industry is experiencing pressure on the net interest margin, that
pressure is especially acute at LSB Corporation as it is so dependent on
borrowings to fund growth.

President Gerald T. Mulligan stated, "We are pleased by the growth in our loan
portfolios which indicates that we are meeting our customers' expectations in
this competitive and challenging environment. In spite of industry reports that
loan demand has diminished with increasing interest rates and credit quality has
worsened, I am happy to report that our non-performing assets are minimal".

As of March 31, 2006, non-performing loans remained low at 0.01% of total loans
while the allowance for loan losses as a proportion of total loans equaled
1.72%.

Total assets increased $24.0 million from December 31, 2005 to $545.8 million as
of March 31, 2006. The increase reflected growth in both residential and
commercial loans as well as in the investment portfolio.

Additionally, the Company transferred approximately $205.8 million of
investments held to maturity into investments available for sale during the
first quarter of 2006. The impact of this change requires the unrealized loss to
be reflected on the balance sheet in the "accumulated other comprehensive loss"
portion of stockholders' equity and totaled $4.0 million. Total accumulated
other comprehensive loss was $5.0 million as of March 31, 2006. Notwithstanding
the change into investments available for sale, the Company and the Bank
continue to maintain strong capital at levels considered "well-capitalized"
under regulatory capital guidelines.

Total deposits decreased slightly from December 31, 2005 and totaled $302.9
million as of March 31, 2006. Asset growth during the first quarter was funded
by advances from the Federal Home Loan Bank. Total borrowed funds increased
during the first quarter of 2006 by $28.4 million or 18.5% and totaled $181.7
million as of March 31, 2006.

The Company also announced a quarterly dividend of $0.14 to be paid on May 25,
2006 to shareholders of record as of May 11, 2006. This dividend represents a
3.12% annualized dividend yield based on the closing stock price of $17.95 on
March 31, 2006.
