              JEFFERSON BANCSHARES, INC. ANNOUNCES EARNINGS FOR THE
                     THREE MONTHS ENDED SEPTEMBER 30, 2009

Morristown, Tennessee -- (October 29, 2009) - Jefferson Bancshares, Inc.
(Nasdaq: JFBI), the holding company for Jefferson Federal Bank, announced net
earnings for the quarter ended September 30, 2009 of $484,000, or $0.08 per
diluted share, compared to net earnings of $533,000, or $0.09 per diluted share,
for the quarter ended September 30, 2008. The 2009 results reflect the Company's
acquisition of State of Franklin Bancshares, Inc., the parent company of State
of Franklin Bank, a Tennessee chartered savings bank headquartered in Johnson
City, Tennessee, (collectively, "State of Franklin") on October 31, 2008.

      Anderson L. Smith, President and Chief Executive Officer commented,
"Financial institutions continue to confront a challenging operating environment
due to the struggling economy and historically low interest rates. Current
economic conditions have impacted the performance of the Company's loan
portfolio, as evidenced by higher charge-offs and an increased provision for
loan losses compared to the prior year. However, our asset quality continues to
compare favorably with industry peers. Non-performing assets to total assets
were 1.42% at September 30, 2009, compared to 1.43% at June 30, 2009, and 0.36%
at September 30, 2008. We are proactive in identifying the risk within our loan
portfolio and in managing problem loans. On the deposit side, we continue to
monitor our deposit mix and deposit pricing and have been successful in
achieving growth in lower costing transaction accounts."

The net interest margin was 3.24% for the quarter ended September 30, 2009
compared to 3.95% for the same period in 2008. The yield on interest-earning
assets declined 70 basis points to 5.47% for the quarter ended September 30,
2009 compared to 6.17% for the same period in 2008 due primarily to reductions
in market interest rates. The yield on assets was impacted in the current
quarter by loan payoffs as well as a higher balance of loans in nonaccrual
status. The cost of interest-bearing liabilities declined 37 basis points to
2.43% for the quarter ended September 30, 2009 compared to 2.80% for the same
period in 2008 primarily due to lower market interest rates.

At September 30, 2009, total assets were $654.5 million compared to $662.7
million at June 30, 2009. Investment securities increased $18.9 million, or
51.7%, to $55.4 million during the quarter ended September 30, 2009 due to
purchases of government agency and U.S. Treasury securities. Net loans decreased
$17.6 million to $480.5 million at September 30, 2009, compared to $498.1
million at June 30, 2009, due primarily to lower loan demand combined with both
residential and commercial loan payoffs during the quarter.

Total deposits decreased $9.1 million to $473.1 million at September 30, 2009
compared to $482.2 million at June 30, 2009 due to the planned runoff of higher
costing time deposits, which was partially offset by increases in money market,
interest-bearing NOW and savings deposits. Time deposits decreased $23.1 million
to $249.0 million at September 30, 2009 compared to June 30, 2009. The average
cost of interest-bearing deposits was 2.15% for the quarter ended September 30,

2009 compared to 2.59% for the corresponding period in 2008. Total Federal Home
Loan Bank advances were virtually unchanged at $90.2 million at September 30,
2009 compared to $90.3 million at June 30, 2009.

Total stockholders' equity increased $1.3 million to $80.8 million at September
30, 2009 compared to $79.5 million at June 30, 2009. Unrealized gains and
losses, net of taxes, in the available-for-sale investment portfolio are
reflected as an adjustment to stockholders' equity. At September 30, 2009, the
adjustment to stockholders' equity was a net unrealized gain of $741,000
compared to a net unrealized gain of $150,000 at June 30, 2009. As of September
30, 2009 the Company had 6,706,489 common shares outstanding with a book value
of $12.05 per common share. The Bank continues to be well-capitalized under
regulatory requirements.

Nonperforming assets represented 1.42% of total assets at September 30, 2009,
compared to 1.43% of total assets at June 30, 2009 and 0.36% of total assets at
September 30, 2008. The level of nonperforming assets increased for the quarter
ended September 30, 2009 compared to the same period in 2008 due to an increase
in nonaccrual real estate loans and repossessed assets. Net charge-offs for the
three months ended September 30, 2009 were $427,000, or 0.35% of average loans
on an annualized basis, compared to $38,000, or 0.05% of average loans on an
annualized basis, for the same period in 2008. The allowance for loan losses was
$4.6 million, or 0.95% of total loans, at September 30, 2009 compared to $4.7
million, or 0.94% of total loans, at June 30, 2009 and $2.0 million, or 0.68% of
total loans, at September 30, 2008. The provision for loan losses totaled
$300,000 for the three months ended September 30, 2009, compared to $160,000 for
the three months ended September 30, 2008. The increase in the provision for
loan losses was primarily the result of the increase in nonaccrual real estate
loans during the 2009 period and current economic conditions.
