SI FINANCIAL GROUP, INC. REPORTS RESULTS FOR THE QUARTER ENDED MARCH 31, 2009

WILLIMANTIC, CONNECTICUT--APRIL 22, 2009. SI Financial Group, Inc. (the
"Company") (NASDAQ Global Market: SIFI), the holding company of Savings
Institute Bank and Trust Company (the "Bank"), reported net income of $56,000,
resulting in negligible basic and diluted earnings per common share, for the
quarter ended March 31, 2009 versus net income of $455,000, or $0.04 basic and
diluted earnings per common share, for the quarter ended March 31, 2008.

Net interest income increased 12.5% to $6.3 million for the quarter ended March
31, 2009 from $5.6 million for the quarter ended March 31, 2008. The increase in
net interest income was due to a higher average balance of loans, federal funds
and other interest-earning assets and a lower cost of funds, offset by a
decrease in the average rate earned on interest-earning assets and an increase
in average deposits and Federal Home Loan Bank borrowings.

The provision for loan losses increased $355,000 to $490,000 for the first
quarter of 2009 compared to the same period in the prior year. The higher
provision in 2009 related to increases in nonperforming loans and charge-offs,
which continue to be impacted by adverse market conditions. At March 31, 2009,
nonperforming loans totaled $9.5 million, compared to $7.7 million at March 31,
2008. Specific reserves relating to nonperforming loans decreased to $498,000 at
March 31, 2009 compared to $1.3 million at March 31, 2008. For the quarter ended
March 31, 2009, net loan charge-offs increased $1.2 million to $1.3 million,
compared to $82,000 for the quarter ended March 31, 2008, primarily due to a
$1.0 million charge-off of a commercial construction loan with a previously
recorded specific reserve.

Noninterest income was $2.5 million for the quarters ended March 31, 2009 and
2008. For the quarter ended March 31, 2009, the Company reported net gains on
the sale of loans of $191,000 resulting from the sale of $15.0 million of
residential mortgage loans, compared to net gains on the sale of loans of
$59,000 resulting from the sale of $5.0 million of residential mortgage loans
for the same period in 2008. Service fees decreased $94,000 as a result of a
decrease in overdraft charges on certain deposit products. The increase of
$27,000 on the sale of primarily mortgage-backed securities was offset by
other-than-temporary impairment charges on two pooled trust preferred securities
totaling $150,000.

Noninterest expenses increased $921,000 for the quarter ended March 31, 2009
compared to the same period in 2008, primarily due to increases in salaries and
benefits, impairment charges on other investments, FDIC assessment and computer
and electronic banking services. Compensation costs increased as a result of
additional salaries and benefits, loan origination commissions and related
payroll taxes. Loan origination commissions increased due to higher residential
mortgage volume related to a decrease in market interest rates. During the first
quarter of 2009, impairment charges of $336,000 were recorded to reduce the
carrying value of the Bank's investment in two small business investment company
limited partnerships. The increase in the 2009 FDIC assessment was attributable
to the expiration of credits during 2008. Computer and electronic banking
services expense rose as a result of increased telecommunication costs and
transaction activity.

Total assets increased $11.4 million, or 1.3%, to $864.5 million at March 31,
2009 from $853.1 million at December 31, 2008. Contributing to the increase in
assets were increases of $13.9 million in cash and cash equivalents and $6.3
million in net loans receivable, offset by a decrease of $8.2 million in
available for sale securities. The increase in net loans receivable represents
an increase in commercial business loans offset by a decrease in residential and
commercial mortgage loans. Commercial business loans increased as a result of
the purchase of $14.9 million in USDA and SBA loans that are fully guaranteed by
the U.S. government. An increase in residential mortgage loan originations of
$21.3 million were partially offset by residential mortgage loan sales of $15.0
million during the quarter ended March 31, 2009. Overall loan originations
increased $4.1 million in the first quarter of 2009 compared to the same period
in 2008. The decrease in available for sale securities reflects the sale of
primarily mortgage-backed securities.

Total liabilities were $792.0 million at March 31, 2009 compared to $780.2
million at December 31, 2008. Deposits increased $15.5 million, or 2.5%, which
included an increase in NOW and money market accounts of $13.6 million,
noninterest-bearing deposits of $989,000 and certificate of deposit accounts of
$956,000. The increase in deposits was due to branch expansion, marketing and
promotional initiatives and competitively priced deposit products. Borrowings
decreased $2.0 million from $147.8 million at December 31, 2008 to $145.8
million at March 31, 2009, resulting from a decrease in Federal Home Loan Bank
advances.

Total stockholders' equity decreased $379,000 from $72.9 million at December 31,
2008 to $72.5 million at March 31, 2009. The decrease in stockholders' equity
was attributable to an increase in net unrealized holding losses on available
for sale securities aggregating $3.4 million (net of taxes), offset by a
cumulative effect adjustment to retained earnings of $2.7 million as a result of
the adoption of Financial Accounting Standards Board Staff Position FAS 115-2
and FAS 124-2, "RECOGNITION AND PRESENTATION OF OTHER-THAN-TEMPORARY
IMPAIRMENTS" ("FSP FAS 115-2 and FAS 124-2") and earnings of $56,000.

The early adoption of FSP FAS 115-2 and FAS 124-2 during the quarter ended March
31, 2009, required management to separately identify whether
other-than-temporary impairment charges totaling $7.1 million that were
previously recognized in earnings during the third and fourth quarters of 2008
were related to credit losses or other noncredit factors at the measurement date
of impairment. Management determined, based on the present value of expected
cash flows in accordance with applicable guidance that $4.0 million of the $7.1
million in other-than-temporary impairment charges were related to noncredit
factors and therefore, recorded a cumulative effect adjustment of $2.7 million
(net of taxes) as a reduction to retained earnings with a corresponding
adjustment to accumulated other comprehensive losses. The Company does not
intend to sell these impaired securities and it is not more likely than not that
the Company will be required to sell these securities before recovery of the
amortized cost basis of each of these securities.

"The results for the first quarter continue to reflect the conservative approach
we have taken since the start of the recession. Adding to the loan loss
allowance and preserving capital is a strategy we believe is both prudent under
the present economic conditions and one that will serve us well as conditions
improve," commented Rheo A. Brouillard, President and Chief Executive Officer.
"The quarter also saw strong deposit growth and significant residential mortgage
loan activity as we continue to be active participants in our market area,"
added Brouillard.
