               JEFFERSON BANCSHARES, INC. ANNOUNCES EARNINGS FOR
                THE QUARTER AND NINE MONTHS ENDED MARCH 31, 2006

Morristown, Tennessee -- (April 28, 2006) - Jefferson Bancshares, Inc. (Nasdaq:
JFBI), the holding company for Jefferson Federal Bank, announced net income of
$476,000, or $0.08 per diluted share, for the quarter ended March 31, 2006
compared to net income of $862,000, or $0.12 per diluted share, for the quarter
ended March 31, 2005. For the nine months ended March 31, 2006, net income was
$2.0 million, or $0.31 per diluted share, compared to $2.7 million, or $0.36 per
diluted share, for the comparable period in 2005. The decline in net income for
the three-month period ended March 31, 2006 was primarily the result of an
increase in noninterest expense, combined with a decrease in net interest
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. The
decline in net income for the nine-month period ended March 31, 2006 was
primarily the result of an increase in noninterest expense, partially offset by
an increase in noninterest income. Annualized return on average assets and
return on average equity for the nine months ended March 31, 2006 were 0.86% and
3.33%, respectively, compared to 1.18% and 4.01% for the corresponding 2005
period.

Anderson L. Smith, President and CEO, commented, "We are pleased that
construction of our Merchants Greene office in Hamblen County, Tennessee is near
completion and scheduled to open in May 2006. Our Farragut office in Knox
County, Tennessee is also near completion and scheduled to open in June 2006. In
addition, we plan to break ground in June 2006 for our second Knoxville location
in the Bearden Hill area. While the costs related to our investment in new
facilities and human resources is a short-term detractor to net earnings, we
anticipate that these investments will position our company for continued growth
and profitability. We continue to experience significant growth in our loan
portfolio while maintaining positive trends in asset quality."

Net interest income decreased $96,000 to $2.7 million for the quarter ended
March 31, 2006 from the corresponding quarter in 2005. The interest rate spread
and net interest margin for the quarter ended March 31, 2006 were 3.04% and
3.80%, respectively, compared to 3.36% and 4.02% for the same period in 2005.
Interest income increased $605,000, or 15.1%, to $4.6 million for the
three-month period ended March 31, 2006 primarily due to growth in average
earning assets and an increase in short-term interest rates. Interest expense
increased $701,000, or 60.2%, to $1.9 million for the quarter ended March 31,
2006, as a result of an increase in deposit rates and an increase in Federal
Home Loan Bank ("FHLB") borrowings. The average rate paid on interest-bearing
liabilities increased 103 basis points to 3.34% for the three months ended March
31, 2006. For the nine months ended March 31, 2006, net interest income
decreased $20,000, to $8.4 million. The interest rate spread and net interest
margin for the nine months ended March 31, 2006 were 3.24% and 3.96%,
respectively, compared to 3.25% and 3.88% for the same period in 2005. Interest
income increased $1.4 million, or 11.9%, to $13.2 million for the nine-month
period ended March 31, 2006 primarily due to an increase of 79 basis points in
the yield on average earning assets combined with changes in the asset mix.
Interest expense increased $1.4 million, or 42.3%, to $4.8 million for the nine
months ended March 31, 2006, as a result of an increase in deposit rates and an
increase in FHLB borrowings.




Noninterest income decreased $14,000, or 4.3%, to $313,000 for the quarter ended
March 31, 2006 and increased $393,000, or 49.8%, to $1.2 million for the nine
months ended March 31, 2006 compared to the corresponding periods in 2005.
Mortgage origination fee income accounted for the largest increase in
noninterest income with $129,000 and $446,000 for the three- and nine-month
periods ended March 31, 2006, respectively, compared to $40,000 for both the
three- and nine-periods in 2005.

Noninterest expense increased $371,000, or 19.4%, to $2.3 million for the
three-month period ended March 31, 2006, primarily due to an increase in
compensation and benefits expense. Compensation and benefits expense increased
$413,000, or 38.6%, to $1.5 million for the three-month period ended March 31,
2006, primarily due to staff additions for our future branch office in
Morristown, Tennessee and two future branch offices in Knoxville, Tennessee that
are anticipated to open during 2006 and early 2007. 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 March 31,
2006, compensation and benefits expense included $66,000 related to the
expensing of stock options. For the nine months ended March 31, 2006,
noninterest expense increased $1.4 million, or 27.0%, to $6.4 million due
primarily to an increase in compensation and benefits expense. Compensation and
benefits expense increased $1.1 million, or 39.4%, to $4.1 million for the nine
months ended March 31, 2006 due to staff additions and stock option expensing.
Compensation and benefits expense related to stock option expense totaled
$199,000 for the nine months ended March 31, 2006. There were 95 full-time
employees at March 31, 2006 compared to 75 full-time employees at March 31,
2005.

Nonperforming assets totaled $223,000, or 0.07% of total assets at March 31,
2006, compared to $1.5 million, or 0.50% of total assets at March 31, 2005.
Annualized net charge-offs for the nine months ended March 31, 2006 were 0.06%
of average loans, compared to 0.09% for the same period in 2005. The allowance
for loan losses was $2.2 million, or 0.90% of total gross loans, at March 31,
2006 compared to $2.3 million, or 1.18% of total gross loans, at March 31, 2005.
There were no additions to the allowance for loan losses for either nine-month
period.

Total assets at March 31, 2006 were $312.4 million compared to $295.0 million at
June 30, 2005. During the nine months ended March 31, 2006, net loans receivable
increased $32.4 million, or 15.6%, to $240.9 million, due to growth in real
estate and consumer loans. Investment securities decreased $13.5 million, or
25.2%, to $39.9 million at March 31, 2006, 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 $2.2 million, to $196.9 million at
March 31, 2006 as a result of a $4.9 million increase in transaction accounts,
more than offsetting a $2.7 million decline in certificates of deposit.
Transaction accounts represented 39.8% of total deposits at March 31, 2006
compared to 37.8% at June 30, 2005 and 35.9% at March 31, 2005. FHLB advances
were $39.0 million at March 31, 2006, an increase of $22.0 million, compared to
$17.0 million at June 30, 2005. We utilize advances from the FHLB as a funding
source for loan growth and to manage daily liquidity needs.




Total equity decreased $6.5 million, or 8.0%, to $75.5 million at March 31, 2006
due to a combination of factors, including the repurchase of shares in the
amount of $8.1 million and dividend payments of $1.2 million, more than
offsetting net income of $2.0 million. Stock repurchases for the three months
ended March 31, 2006 totaled 210,695 shares at an average cost of $13.44 per
share. On February 24, 2006, the Company announced its third stock repurchase
program in which 690,261 shares, or 10% of the Company's outstanding common
stock, may be repurchased. At March 31, 2006, 655,634 shares remained eligible
for repurchase under the current stock repurchase program.
