JEFFERSON BANCSHARES, INC. ANNOUNCES EARNINGS FOR THE QUARTER
                     AND SIX MONTHS ENDED DECEMBER 31, 2005

Morristown, Tennessee -- (January 27, 2006) - Jefferson Bancshares, Inc.
(Nasdaq: JFBI), the holding company for Jefferson Federal Bank, announced net
income of $710,000, or $0.11 per diluted share, for the quarter ended December
31, 2005 compared to net income of $882,000, or $0.12 per diluted share, for the
quarter ended December 31, 2004. For the six months ended December 31, 2005, net
income was $1.5 million, or $0.23 per diluted share, compared to $1.8 million,
or $0.24 per diluted share, for the comparable period in 2004. The decline in
net income for both the three and six month period ended December 31, 2005 was
the result of an increase in noninterest expense, partially offset by an
increase in net interest income and noninterest income. The increase in
noninterest expense was the result of our expansion activities, as well as our
adoption of Financial Accounting Standards Board's ("FASB") Statement 123R,
which requires the expensing of stock options. Annualized return on average
assets and return on average equity for the six months ended December 31, 2005
was .99% and 3.74%, respectively, compared to 1.19% and 4.02% for the
corresponding period in 2004.

Anderson L. Smith, President and CEO, commented, "We remain focused on our
expansion initiatives in both Morristown and Knoxville, Tennessee and the
opportunity to enhance long-term value for our shareholders. The first year
performance of our Knoxville operation has been consistent with our expectations
and we look forward to expanding our presence in Knoxville. We are pleased that
our investment in new facilities and human resources, combined with the
additional expense of regulatory and Sarbanes-Oxley compliance, has had a
minimal impact on earnings per share. We are encouraged by the significant
growth in our loan portfolio and modest improvement in net interest income.
Although the increase in short-term interest rates has improved the yield on
earning assets, our cost of funds has also been affected by the increase in
rates."

Net interest income increased $55,000 to $2.8 million for the quarter ended
December 31, 2005 from the corresponding quarter in 2004. The interest rate
spread and net interest margin for the quarter ended December 31, 2005 were
3.33% and 4.03%, respectively, compared to 3.23% and 3.84% for the same period
in 2004. Interest income increased $494,000, or 12.7%, to $4.4 million for the
three-month period ended December 31, 2005 primarily due to an increase in short
term interest rates in addition to changes in the asset mix. Interest expense
increased $439,000, or 39.5%, to $1.6 million for the quarter ended December 31,
2005, primarily due to an increase in deposit rates and an increase in Federal
Home Loan Bank borrowings. The average rate paid on interest-bearing liabilities
increased 75 basis points to 2.90% for the three months ended December 31, 2005.
For the six months ended December 31, 2005, net interest income increased
$76,000, or 1.4%, to $5.7 million. The interest rate spread and net interest
margin for the six months ended December 31, 2005 were 3.35% and 4.04%,
respectively, compared to 3.20% and 3.81% for the same period in 2004. Interest
income increased $800,000, or 10.3%, to $8.6 million for the six-month period
ended December 31, 2005 primarily due to an increase of 82 basis points in the
yield on earning assets combined with changes in the asset mix. Interest expense
increased $724,000, or 32.8%, to $2.9 million for the six months ended December
31, 2005, primarily due to an increase in deposit rates and an increase in
Federal Home Loan Bank ("FHLB") borrowings.





Noninterest income increased $197,000, or 91.2%, to $413,000 for the quarter
ended December 31, 2005 from the corresponding 2004 quarter. Mortgage
origination fee income accounted for the largest increase in noninterest income
with $131,000 for the current three-month period and no comparable income from
mortgage originations in 2004. Gain on sale of foreclosed property was $83,000
for the three months ended December 31, 2005 compared to $5,000 for the same
period in 2004. For the six months ended December 31, 2005, noninterest income
increased $408,000, or 80.8%, to $913,000. Mortgage origination fee income
accounted for the largest increase in noninterest income with $317,000 for the
current six-month period and no comparable income from mortgage originations in
2004. Gain on sale of foreclosed property was $160,000 for the six months ended
December 31, 2005 compared to $33,000 for the same period in 2004.

Noninterest expense increased $502,000, or 31.7%, to $2.1 million for the
three-month period ended December 31, 2005, primarily due to an increase in
compensation and benefits expense. Compensation and benefits expense increased
$394,000, or 43.5%, to $1.3 million for the three-month period ended December
31, 2005, primarily due to staff additions for the lending office in Knoxville,
Tennessee which opened on January 1, 2005, and staff additions for our future
branch office in Morristown, Tennessee and two future branch offices in
Knoxville, Tennessee which are anticipated to open during 2006. On July 1, 2005,
we adopted FASB Statement No.123R, "Share-Based Payment" which requires the
expensing of stock options at fair value. Accordingly, for the three months
ended December 31, 2005, compensation and benefits expense included $66,000
related to the expensing of stock options. For the six months ended December 31,
2005, noninterest expense increased $1.0 million, or 31.2%, to $4.2 million due
primarily to an increase in compensation and benefits expense. Compensation and
benefits expense increased $736,000, or 39.9%, to $2.6 million for the six
months ended December 31, 2005 due to staff additions and stock option
expensing. Compensation and benefits expense related to stock option expense
totaled $133,000 for the six months ended December 31, 2005. There were 85
full-time employees at December 31, 2005 compared to 68 full-time employees at
December 31, 2004.

Nonperforming assets totaled $772,000, or 0.25% of total assets at December 31,
2005, compared to $1.3 million, or 0.45% of total assets at June 30, 2005.
Annualized net charge-offs for the six months ended December 31, 2005 were .05%
of average loans, compared to .09% for the same period in 2004. The allowance
for loan losses was $2.2 million, or 0.97% of total gross loans, at December 31,
2005 compared to $2.3 million, or 1.09% of total gross loans, at June 30, 2005.
There were no additions to the allowance for loan losses for either period.

Total assets at December 31, 2005 were $306.1 million compared to $295.0 million
at June 30, 2005. During the six months ended December 31, 2005, net loans
receivable increased $19.2 million, or 9.2%, to $227.7 million, due to growth in
real estate and consumer loans. Investment securities decreased $6.6 million, or
12.3%, to $46.8 million at December 31, 2005, compared to $53.4 million at June
30, 2005 due primarily to sales of investment securities. Proceeds from the sale
of investment securities were used to fund stock repurchases and to fund growth
in the loan portfolio. Total deposits increased $494,000 to $195.2 million at
December 31, 2005 as a result of a $3.5 million increase in transaction
accounts, more than offsetting a $3.0 million decrease in certificates of
deposit. Transaction accounts represented 39.5% of total deposits at December
31, 2005 compared to 37.8% at June 30, 2005 and 33.4% at December 31, 2004.





Total equity decreased $4.1 million, or 5.0%, to $77.9 million at December 31,
2005 due to a combination of factors, including the repurchase of shares in the
amount of $5.2 million and dividend payments of $843,000, more than offsetting
net income of $1.5 million. Stock repurchases for the three months ended
December 31, 2005 totaled 257,223 shares at an average cost of $13.32 per share.
An additional 176,068 shares remain eligible for repurchase under the current
stock repurchase program.
