JEFFERSON BANCSHARES, INC. ANNOUNCES EARNINGS FOR THE
                        QUARTER ENDED SEPTEMBER 30, 2006

Morristown, Tennessee -- (October 27, 2006) - Jefferson Bancshares, Inc.
(Nasdaq: JFBI), the holding company for Jefferson Federal Bank, announced net
income of $290,000, or $0.05 per diluted share, for the quarter ended September
30, 2006 compared to net income of $785,000, or $0.12 per diluted share, for the
quarter ended September 30, 2005. The decline in net income for the three-month
period ended September 30, 2006 was primarily the result of a decrease in net
interest income and noninterest income combined with an increase in noninterest
expense. The increase in noninterest expense was attributable to the staffing
and operational costs of two new full-service offices and our future branch
office scheduled to open in 2007. Return on average assets and return on average
equity for the quarter ended September 30, 2006 were 0.35% and 1.55%,
respectively, compared to 1.05% and 3.87% for the corresponding 2005 period.

Anderson L. Smith, President and Chief Executive Officer, commented, "The
interest rate environment continues to be challenging for financial institutions
and competition for loans and deposits is very intense. Despite this difficult
environment, we have achieved strong loan and deposit growth during the quarter
while maintaining positive trends in asset quality. Our recent additions 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 adversely affected our current earnings,
we feel that we are positioning the Company for future growth and building the
value of our franchise."

Net interest income decreased $65,000 to $2.7 million for the quarter ended
September 30, 2006 from the corresponding quarter in 2005. The interest rate
spread and net interest margin for the quarter ended September 30, 2006 were
2.86% and 3.65%, respectively, compared to 3.38% and 4.06% for the corresponding
2005 period. Interest income increased $940,000, or 22.4%, to $5.1 million for
the three-month period ended September 30, 2006 due to growth in average earning
assets and an increase in short-term interest rates. The average yield earned on
interest-earning assets increased 77 basis points to 6.82% for the three months
ended September 30, 2006. Interest expense increased $1.0 million, or 72.8%, to
$2.4 million for the quarter ended September 30, 2006 as a result of an increase
in the volume and rate paid on interest-bearing liabilities. The average rate
paid on interest-bearing liabilities increased 129 basis points to 3.95% for the
three months ended September 30, 2006.

Noninterest income decreased $69,000, or 15.1%, to $387,000 for the quarter
ended September 30, 2006 compared to the corresponding 2005 period due to a
combination of factors including decreases in mortgage origination income,
service charges and gain on sale of foreclosed property more than offsetting a
decrease in loss on sale of investment securities.




Noninterest expense increased $591,000, or 28.5%, to $2.7 million for the
three-month period ended September 30, 2006 compared to the corresponding 2005
period due to a combination of factors including increases in expenses for
compensation and benefits, occupancy, advertising and equipment and data
processing. Compensation and benefits expense increased $262,000, or 20.5%, to
$1.5 million for the three-month period ended September 30, 2006 primarily due
to staff additions for our branch offices in Hamblen and Knox Counties and our
future branch office in Knox County that is anticipated to open in 2007. There
were 95 full-time employees at September 30, 2006 compared to 81 full-time
employees at September 30, 2005. Increases in advertising, occupancy, equipment
and data processing expenses were also the result of our recent expansion
activities.

Nonperforming assets totaled $271,000, or 0.08% of total assets at September 30,
2006, compared to $480,000, or 0.16% of total assets at September 30, 2005 due
to a decline in repossessed assets. Net charge-offs for the quarter ended
September 30, 2006 were $28,000, or 0.04% of average loans, compared to $12,000,
or 0.02% of average loans for the quarter ended September 30, 2005. The
allowance for loan losses was $2.1 million, or 0.80% of total gross loans, at
September 30, 2006 compared to $2.3 million, or 1.05% of total gross loans, at
September 30, 2005. There were no additions to the allowance for loan losses for
either three-month period.

Total assets at September 30, 2006 were $331.4 million compared to $327.1
million at June 30, 2006. During the quarter ended September 30, 2006, net loans
receivable increased $10.9 million, or 4.3%, to $265.0 million, primarily due to
growth in real estate loans. Total deposits increased $9.3 million, or 4.7%,
during the quarter to $208.1 million at September 30, 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 Federal Home Loan Bank advances during the
quarter ended September 30, 2006. Federal Home Loan Bank advances were $47.9
million at September 30, 2006, a decrease of $4.5 million compared to $52.4
million at June 30, 2006.

Total equity decreased $101,000, to $74.4 million at September 30, 2006 due
primarily to the repurchase of shares in the amount of $633,000. Stock
repurchases for the three months ended September 30, 2006 totaled 47,351 shares
at an average cost of $13.38 per share. On February 24, 2006, the Company
announced its third stock repurchase program in which up to 690,261 shares, or
10% of the Company's outstanding common stock, may be repurchased. At September
30, 2006, 526,923 shares remained eligible for repurchase under the current
stock repurchase program. The Company paid a $0.06 per share dividend to
shareholders during the quarter ended September 30, 2006 totaling $396,000.
