              JEFFERSON BANCSHARES ANNOUNCES THIRD QUARTER RESULTS

Morristown, Tennessee -- (April 29, 2005) - Jefferson Bancshares, Inc. (Nasdaq:
JFBI), the holding company for Jefferson Federal Bank, announced net income of
$862,000, or $0.12 per diluted share, for the quarter ended March 31, 2005
compared to net income of $1.0 million, or $0.13 per diluted share, for the
quarter ended March 31, 2004. Net income for the three-month period in 2005
reflects an increase in noninterest expense related to the lending office in
Knoxville, Tennessee which opened on January 1, 2005. The most significant item
contributing to the overall increase in noninterest expense was compensation
expense, which increased $170,000 for the quarter ended March 31, 2005 compared
to the same period in 2004. For the nine-month period ended March 31, 2005, the
Company reported net income of $2.7 million compared to net income of $408,000
for the comparable period in 2004. Net income for the nine-month period in 2004
reflects the nonrecurring expense associated with the $4.0 million contribution
to the Jefferson Federal Charitable Foundation which was formed in connection
with the Company's conversion and was funded with $250,000 and 375,000 shares of
Jefferson Bancshares common stock. This stock and cash contribution was recorded
as an expense of $4.0 million, or approximately $2.5 million after income taxes.

Net interest income decreased $31,000, or 1.1%, to $2.8 million for the quarter
ended March 31, 2005. The net interest margin improved 15 basis points to 4.02%
for the quarter ended March 31, 2005. Interest income remained steady at $4.0
million for the current three-month period as a decline in the volume of
interest-earning assets was offset by an increase in the average yield. Interest
expense increased $35,000, or 3.1%, to $1.2 million for the quarter ended March
31, 2005, primarily due to an increase in the average rate paid on deposits. The
interest rate spread was 3.36% and 3.20% for the quarters ended March 31, 2005
and 2004, respectively. For the nine months ended March 31, 2005, net interest
income decreased $64,000 to $8.4 million due primarily to a decrease in the
volume of investment securities. For the nine months ended March 31, 2005, the
interest rate spread and net interest margin was 3.25% and 3.88%, respectively,
compared to 3.02% and 3.73% for the same period in 2004.

Noninterest income increased $62,000, or 23.4%, to $327,000 for the three months
ended March 31, 2005 primarily due to an increase in mortgage origination fee
income, an increase in gain on sale of foreclosed property and an increase in
the cash surrender value of bank owned life insurance more than offsetting a
decline in service charges and fees. Noninterest income increased $38,000, or
5.1%, to $789,000 for the nine months ended March 31, 2005 as a result of an
increase in mortgage origination fee income and an increase in the cash
surrender value of bank owned life insurance more than offsetting a decline in
service charges and fees and a loss on sale of investment securities.

Noninterest expense increased $245,000, or 14.7%, to $1.9 million for the
three-month period ended March 31, 2005, primarily due to an increase in
compensation expense. Compensation expense increased $170,000, or 18.9%, to $1.1
million for the current three-month period primarily due to staff additions for
the lending office in Knoxville, Tennessee which opened on January 1, 2005.
Consulting fees relating to the internal control requirement of the
Sarbanes-Oxley Act of 2002 amounted to $50,000 for the three-month period ended
March 31, 2005. We expect that ongoing fees for professional services will
exceed historical levels due to the Sarbanes Oxley Act of 2002. For the
nine-month period ended March 31, 2005, noninterest expense totaled $5.1 million
compared to $8.7 million for the same period in 2004. The $3.7 million decrease
was primarily attributable to the nonrecurring expense associated with the $4.0
million contribution to the Jefferson Federal Charitable Foundation during the
nine months ended March 31, 2004.

Nonperforming assets totaled $1.5 million at March 31, 2005, compared to $1.6
million at June 30, 2004 and $2.0 million at March 31, 2004. There were no
additions to the allowance for loan losses for either period. The allowance for
loan losses was $2.3 million, or 1.18% of total gross loans, at March 31, 2005
compared to $2.5 million, or 1.34% of total gross loans, at March 31, 2004. Net
charge-offs amounted to $50,000 and $141,000 for the three- and nine-month
period ended March 31, 2005 compared to $58,000 and $317,000 for the comparable
periods in 2004.


Total assets at March 31, 2005 were $294.5 million compared to $305.5 million at
June 30, 2004. Total loans increased $8.3 million, or 4.5%, to $194.9 million at
March 31, 2005, compared to $186.6 million at June 30, 2004. Investment
securities decreased $24.9 million, or 26.2%, to $70.1 million at March 31,
2005, compared to $95.0 million at June 30, 2004. The decrease in investment
securities was due primarily to the deployment of conversion proceeds into stock
repurchases and higher yielding assets. Total deposits decreased $8.2 million,
or 4.0%, to $196.6 million at March 31, 2004 due to a decline in certificates of
deposit more than offsetting an increase in demand deposits.

Total equity decreased $8.4 million, or 9.0%, to $85.0 million at March 31, 2005
due to a combination of factors, including the repurchase of shares in the
amount of $10.9 million and dividend payments of $1.2 million more than
offsetting net income of $2.7 million.

Return on average assets for the nine months ended March 31, 2005 was 1.18%
compared to 0.44% for the year ended June 30, 2004. Return on average equity was
4.01% for the nine months ended March 31, 2005 compared to 1.46% for the year
ended June 30, 2004. The improvement in the return on average equity was aided
by stock repurchases during the current nine-month period.

Stock repurchases for the three and nine months ended March 31, 2005 totaled
255,356 shares at an average cost of $13.24 per share and 828,552 shares at an
average cost of $13.21 per share, respectively. An additional 10,000 shares
remain eligible for repurchase under the current stock repurchase program.
