JEFFERSON BANCSHARES, INC. ANNOUNCES EARNINGS FOR THE QUARTER
                      AND NINE MONTHS ENDED MARCH 31, 2008

Morristown, Tennessee -- (May 2, 2008) - Jefferson Bancshares, Inc. (NASDAQ:
JFBI), the holding company for Jefferson Federal Bank, announced net income of
$495,000, or $0.09 per diluted share, for the quarter ended March 31, 2008,
compared to net income of $454,000, or $0.07 per diluted share, for the quarter
ended March 31, 2007. The increase in net income was attributable to an increase
in net interest income and noninterest income, as well as a decrease in
noninterest expense more than offsetting an increase in the provision for loan
losses.

Financial results for the nine months ended March 31, 2008 included a $637,000
non-cash charge to deferred income tax expense to establish a valuation
allowance against deferred tax assets. The deferred tax asset written down was
the charitable contribution carryforward directly attributable to the
contribution made to the Jefferson Federal Charitable Foundation in connection
with the Company's public offering in July 2003. The tax benefit of the
contribution may not be fully utilized based on our assessment of future taxable
income within the time allowed by the Internal Revenue Service. This charge to
deferred income tax expense resulted in net income of $753,000, or $0.13 per
diluted share, for the nine months ended March 31, 2008 compared to net income
of $1.1 million, or $0.18 per diluted share, for the corresponding period in
2007. Excluding this tax charge, core net earnings were $1.4 million, or $0.24
per diluted share, for the nine months ended March 31, 2008 compared to GAAP
earnings of $1.1 million, or $0.18 per diluted share, for the corresponding 2007
period. (1)

Anderson L. Smith, President and Chief Executive Officer, commented, "We are
pleased to report solid financial results for the quarter, given a challenging
interest rate environment and an uncertain economy. Despite competitive
pressures, we continue to emphasize asset quality and disciplined deposit and
loan growth."

Net interest income increased $69,000, or 2.4%, to $2.9 million for the quarter
ended March 31, 2008 from the corresponding period in 2007. The interest rate
spread and net interest margin for the quarter ended March 31, 2008 were 3.01%
and 3.75%, respectively, compared to 2.98% and 3.79% for the same period in
2007. The increase in net interest income was driven by lower interest expense,
primarily on Federal Home Loan Bank ("FHLB") borrowings.

For the nine months ended March 31, 2008, net interest income increased
$369,000, or 4.4%, to $8.8 million. The interest rate spread and net interest
margin for the nine months ended March 31, 2008 were 2.97% and 3.73%,
respectively, compared to 2.89% and 3.69% for the same period in 2007. The
increase in net interest income was attributable to an increase in interest
income. Interest income increased $513,000, or 3.3%, to $16.1 million for the
nine months ended March 31, 2008 primarily due to a higher average balance of
loans.




Noninterest income increased $54,000, or 16.7%, to $378,000 for the three months
ended March 31, 2008 and increased $116,000, or 11.4%, to $1.1 million for the
nine months ended March 31, 2008 compared to the corresponding 2007 periods. The
largest increase in noninterest income for both periods was in service charges
and fees, which increased $90,000, or 67.7%, for the three months ended March
31, 2008 and increased $148,000, or 38.6%, for the nine months ended March 31,
2008.

Noninterest expense decreased $159,000, or 6.5%, to $2.3 million for the
three-month period ended March 31, 2008 and decreased $257,000, or 3.4%, to $7.4
million for the nine-month period ended March 31, 2008 compared to the
corresponding periods in 2007 primarily as a result of a decrease in
compensation and benefits expense. Compensation and benefits expense decreased
$198,000, or 13.3%, to $1.3 million for the three-month period ended March 31,
2008 and decreased $364,000, or 8.0%, to $4.2 million for the nine-month period
ended March 31, 2008 due to a lower number of employees.

Nonperforming assets increased to 0.25% of total assets at March 31, 2008,
compared to 0.14% of total assets at March 31, 2007, primarily due to an
increase in foreclosed real estate. The increase in foreclosed real estate was
attributable to one commercial relationship that included foreclosed property
totaling $300,000. Net charge-offs for the quarter increased as a result of the
evaluation and resulting write-down of this commercial foreclosed real estate to
fair value. Net charge-offs for the quarter ended March 31, 2008 were $265,000,
or 0.37% of average loans on an annualized basis, compared to $60,000, or 0.09%
of average loans on an annualized basis, for the same period in 2007. The
allowance for loan losses was $1.8 million, or 0.64%, of total gross loans, at
March 31, 2008 compared to $2.0 million, or 0.76%, of total gross loans at March
31, 2007. A provision for loan losses of $243,000 was recorded for the three
months ended March 31, 2008 primarily as a result of growth in the loan
portfolio and current economic conditions, compared to no provision for the
comparable period in 2007.

Total assets at March 31, 2008 were $334.0 million compared to $339.7 million at
June 30, 2007. For the first nine months of fiscal 2008, net loans receivable
increased $7.2 million, or 2.6%, to $282.1 million, primarily due to an increase
in real estate and commercial loans. However, loan growth slowed during the
three months ended March 31, 2008 due to higher repayments of existing loans,
increased competition on loan pricing, and a weakened real estate market. Total
deposits increased $7.5 million, or 3.4%, to $227.6 million at March 31, 2008
due to a continued emphasis on increasing the number of retail and business
transaction accounts. FHLB advances decreased $11.8 million to $33.0 million at
March 31, 2008, compared to $44.8 million at June 30, 2007. Proceeds from called
investment securities were used to repay borrowings during the three months
ended March 31, 2008.

Total stockholders' equity amounted to $72.4 million at March 31, 2008. Stock
repurchases during the quarter ended March 31, 2008 totaled 99,024 shares at an
average cost of $10.72 per share. On February 24, 2006, the Company announced
its third stock repurchase program under which up to 690,261 shares, or 10% of
the Company's outstanding common stock, may be repurchased. At March 31, 2008,
128,855 shares remained eligible for repurchase under the current stock
repurchase program. The Company declared a $0.06 per share dividend, totaling
$372,000, to shareholders of record on March 31, 2008.

                  RECONCILIATION OF GAAP AND CORE NET EARNINGS
                                   (Unaudited)


      (1)  While core net earnings is not a measure of performance calculated in
accordance with GAAP, the Company believes that this measure is important for
the nine month period ended March 31, 2008 to convey to investors the Company's
earnings for this period absent the $637,000 non-cash charge to deferred income
tax expense to establish a valuation allowance against deferred tax assets
during the quarter ended December 31, 2007. The valuation allowance was related
to the charitable contribution carryforward directly attributable to the
Company's contribution to the Jefferson Federal Charitable Foundation in July
2003. The Company calculated its core net earnings for the nine month period
ended March 31, 2008 by subtracting this $637,000 non-cash charge from net
income for the period. Core net earnings should not be considered in isolation
or as a substitute for net income, cash flows from operating activities or other
income or cash flow statement data calculated in accordance with GAAP. Moreover,
the manner in which the Company calculates core net earnings may differ from
that of other companies reporting measures with similar names. Reconciliation of
the Company's GAAP and core net earnings for the nine period ended March 31,
2008 follows.
