JEFFERSON BANCSHARES, INC. ANNOUNCES EARNINGS FOR THE
                         QUARTER ENDED DECEMBER 31, 2006

Morristown, Tennessee -- (January 26, 2007) - Jefferson Bancshares, Inc.
(Nasdaq: JFBI), the holding company for Jefferson Federal Bank, announced net
income of $349,000, or $0.06 per diluted share, for the quarter ended December
31, 2006 compared to net income of $710,000, or $0.11 per diluted share, for the
quarter ended December 31, 2005. For the six months ended December 31, 2006, net
income was $639,000, or $0.11 per diluted share, compared to $1.5 million, or
$0.23 per diluted share, for the comparable period in 2005. The decline in net
income for both the three- and six-month periods ended December 31, 2006 was
primarily the result of a decline in noninterest income combined with an
increase in noninterest expense. The increase in noninterest expense continues
to reflect our expansion initiatives during the past year. Return on average
assets and return on average equity for the six months ended December 31, 2006
were 0.39% and 1.71%, respectively, compared to 0.99% and 3.74% for the
corresponding period in 2005.

Anderson L. Smith, President and Chief Executive Officer, commented, "We expect
2007 to be a challenging year due to the interest rate environment and continued
competitive pressures. We have executed a number of initiatives that will offer
convenience and value to our customers and we will continue to explore new
products and services that will further enhance our delivery system. Our
additions during the past year of the Merchants-Greene office in Hamblen County
and our Farragut office in Knox County have allowed us to expand our customer
base, and construction on our second Knoxville office is underway with an
estimated completion date of mid 2007. While our recent expansion efforts have
resulted in increased overhead, we feel that we are positioning the Company for
future growth and building the value of our franchise. Our priorities for 2007
include achieving growth in earning assets while controlling both funding costs
and operating expenses."

Net interest income decreased $33,000, or 1.2%, to $2.8 million for the quarter
ended December 31, 2006 from the corresponding quarter in 2005. The interest
rate spread and net interest margin for the quarter ended December 31, 2006 were
2.88% and 3.69%, respectively, compared to 3.33% and 4.03% for the same period
in 2005. Interest income increased $844,000, or 19.2%, to $5.2 million for the
three-month period ended December 31, 2006 as a result of growth in the average
balance of loans and an increase in interest rates. The average yield earned on
interest-earning assets increased 65 basis points to 6.88% for the three months
ended December 31, 2006. Interest expense increased $877,000, or 56.5%, to $2.4
million for the quarter ended December 31, 2006, primarily due to an increase in
interest rates and an increase in the average balance of both deposits and
Federal Home Loan Bank ("FHLB") borrowings. The average rate paid on
interest-bearing liabilities increased 110 basis points to 4.00% for the three
months ended December 31, 2006.

$98,000, or 1.7%, to $5.6 million. The interest rate spread and net interest
margin for the six months ended December 31, 2006 were 2.87% and 3.67%,
respectively, compared to 3.35% and 4.04% for the same period in 2005. Interest
income increased $1.8 million, or 20.8%, to $10.4 million for the six-month
period ended December 31, 2006 primarily due to an increase of 71 basis points
in the yield on earning assets combined with growth in the average balance of
loans. Interest expense increased $1.9 million, or 64.2%, to $4.8 million for
the six months ended December 31, 2006, primarily due to an increase in interest
rates and an increase in the average balance of both deposits and FHLB advances.
The average rate paid on interest-bearing liabilities increased 119 basis points
to 3.98% for the six months ended December 31, 2006.

Noninterest income decreased $103,000, or 24.9%, to $310,000 for the three

corresponding 2005 period. Mortgage origination fee income decreased $29,000, or
22.1%, to $102,000 for the three months ended December 31, 2006 and decreased
$65,000, or 20.5%, to $252,000 for the six-month period ended December 31, 2006
due to a lower volume of loan originations. Gains on foreclosed real estate
decreased $62,000, or 74.7%, to $21,000 for the three months ended December 31,
2006 and decreased $126,000, or 78.8%, to $34,000 for the six-month period ended
December 31, 2006.

Noninterest expense increased $452,000, or 21.7%, to $2.5 million for the
three-month period ended December 31, 2006 and increased $1.0 million, or 25.1%,
to $5.2 million for the six-month period ended December 31, 2006 compared to the
corresponding periods in 2005 due to staff additions and operating expenses
associated with our expansion initiatives. Compensation and benefits expense
increased $199,000, or 15.3%, to $1.5 million for the three-month period ended
December 31, 2006 and increased $461,000, or 17.9%, to $3.0 million for the six
months ended December 31, 2006. There were 94 full-time employees at December

2006, compared to $772,000, or 0.25% of total assets at December 31, 2005.
Annualized net charge-offs for the six months ended December 31, 2006 were 0.07%
of average loans, compared to 0.05% for the same period in 2005. The allowance
for loan losses was $2.1 million, or 0.78% of total gross loans, at December 31,
2006 compared to $2.2 million, or 0.97% of total gross loans, at December 31,
2005. The provision for loan losses totaled $30,000 for both the three and six
months ended December 31, 2006 as a result of growth in the loan portfolio,
compared to no provision for the comparable periods in 2005.

Total assets at December 31, 2006 were $330.4 million compared to $327.1 million
at June 30, 2006. Net loans receivable increased $14.4 million, or 5.7%, to
$268.5 million at December 31, 2006, primarily due to growth in commercial real
estate loans. Total deposits increased $11.1 million, or 5.6%, to $209.9 million
at December 31, 2006 as a result of marketing efforts and promotions associated
with the opening of our two new full-service offices. The increase in deposits
has provided funding for loan growth and reduced our reliance on FHLB advances
during the six months ended December 31, 2006. FHLB advances were $45.3 million
at December 31, 2006, a decrease of $7.1 million, or 13.5%, compared to $52.4
million at June 30, 2006.




Total equity decreased $317,000, to $74.2 million at December 31, 2006 due
primarily to the repurchase of shares in the amount of $1.4 million. Stock
repurchases for the three months ended December 31, 2006 totaled 57,562 shares
at an average cost of $13.10 per share. On February 24, 2006, the Company

10% of the Company's outstanding common stock, may be repurchased. At December
