Board of Directors declares cash dividend of $.07 per common share

Evansville, Ind. (August 1, 2011) — Old National Bancorp (NYSE: ONB) continued its strong, consistent 2011 performance today when it reported 2^nd quarter net income of $17.0 million, or $.18 per share. These results — which exceeded analysts’ consensus estimates for the quarter — outpaced the net income of $16.4 million, or $.17 per share, reported in 1^st quarter 2011. They also represent a substantial increase of 61.7% over Old National’s 2^nd quarter 2010 net income of $10.5 million, or $.12 per share.

“These strong results demonstrate Old National’s ability to grow revenue while managing risk and expenses, and they reinforce our continued strength as a secure, client-focused community bank,” said Bob Jones, Old National Bancorp President and CEO. “Not only did our net income increase nearly 62% over 2^nd quarter 2010, our net interest margin continued to improve and our credit remained well controlled.

“We were also successful in controlling non-interest expenses for the quarter despite having to account for merit increases and one-time costs of $2.2 million related to the Monroe Bank acquisition we completed earlier this year,” Jones continued. “When you consider our early success with Monroe and its positive impact on our revenue and income, and then factor in our just-announced FDIC-assisted acquisition of all 52 Integra Bank branches, you can see that Old National is well-positioned for future success.” (See FDIC-Assisted Acquisition below for more details about this transaction, which was publicly announced Friday, July 29).

Old National Bancorp’s Board of Directors declared a common stock dividend of $.07 per share on the Company’s outstanding shares. This dividend is payable September 15, 2011, to shareholders of record on September 1, 2011. For purposes of broker trading, the ex-date of the cash dividend is August 30, 2011.

FDIC-Assisted Acquisition

As detailed in a news release distributed on Friday, July 29, Old National Bancorp has entered into a purchase and assumption agreement with loss share arrangements with the Federal Deposit Insurance Corporation (FDIC) to assume substantially all deposits of Integra Bank, a full service community bank headquartered in Evansville, Ind. With this acquisition, Old National now operates a total of 52 former Integra banking centers in Southern Illinois, Southern Indiana and Western Kentucky resulting in more than 220 total banking centers within its footprint. This acquisition is expected to be immediately accretive to 2011 earnings, excluding anticipated one-time charges.

Committed to our Strategic Imperatives

Old National’s strong, consistent 2011 performance can be attributed to our unwavering commitment to the following strategic imperatives:

	1.		Strengthen the risk profile.
	2.		Enhance management discipline.
	3.		Achieve consistent quality earnings.

1. Strengthen the Risk Profile

Provision expense for the 2^nd quarter — at $3.2 million — was slightly lower than the $3.3 million recorded in 1^st quarter 2011 and significantly lower than the $8.0 million recorded in 2^nd quarter 2010. Old National’s net charge-offs for the quarter were $5.8 million, an increase of $2.9 million from the $2.9 million reported in 1^st quarter 2011 and a $2.4 million decrease from the $8.2 million in net charge-offs reported in 2^nd quarter 2010.

Old National’s allowance for loan losses at June 30, 2011, was $70.2 million, or 1.70% of total loans, compared to an allowance of $72.7 million, or 1.74% of total loans at March 31, 2011, and $71.9 million, or 1.93% of total loans, at June 30, 2010. The coverage of allowance to non-performing loans remained relatively stable at 59% at June 30, 2011, compared to 60% at March 31, 2011.

“Our 2^nd quarter 2011 results continued to reflect the impact of loans acquired as part of our Monroe Bank partnership, which was completed in the 1^st quarter of 2011,” said Chief Credit Officer Daryl Moore. “The Monroe Bancorp loan portfolio, in accordance with accounting for business combinations, was recorded at fair value with no allowance brought forward on these acquired loans. This was an expected result of our Monroe acquisition, and I’m pleased to say that our overall credit quality remains well-controlled.”

2. Enhance Management Discipline

Expense Management

For the 2^nd quarter, Old National reported total noninterest expenses of $79.8 million, which were comparable to 1^st quarter 2011 noninterest expenses of $79.9 million. Noninterest expenses for 2^nd quarter 2011 included $7.0 million of Monroe-related expenses — of which $2.2 million were integration and conversion charges. Noninterest expenses for 1^st quarter 2011 included $7.9 million of Monroe-related expenses — of which $3.6 million were integration and conversion charges.

“Expense management continues to be an important part of our strategy in the current economic environment,” said President and CEO Bob Jones. “I’m extremely pleased that reported noninterest expenses were flat despite the fact that 2^nd quarter 2011 included approximately $.9 million in annual merit increases.”

Capital Management

Old National’s capital position remained well above industry requirements at June 30, 2011, with regulatory tier 1 and total risk-based capital ratios of 13.4% and 14.9%, respectively, compared to 12.8% and 14.3% at March 31, 2011, and 15.1% and 17.0% at June 30, 2010.

The ratio of tangible common equity to tangible assets rose to 9.52% at June 30, 2011, compared to 9.12% at March 31, 2011, and 9.03% at June 30, 2010. Refer to Table 1 for Non-GAAP reconciliations.

Chris Wolking, Chief Financial Officer, noted: “Old National continues to operate from a very strong capital and liquidity position, which not only provides comfort to our clients, shareholders and the communities we serve, but which also positions Old National to continue to actively pursue merger and acquisition opportunities.”

Balance Sheet and Net Interest Margin

Old National continues to enjoy growth in its residential real estate portfolio, which increased to $801.5 million at June 30, 2011, compared to $782.9 million at March 31, 2011. Loan demand in all other categories remains challenging, as Old National’s total loan portfolio decreased $70.5 million to $4.123 billion at June 30, 2011, from $4.194 billion at March 31, 2011. On average, total loans were $4.157 billion for 2^nd quarter 2011 compared to $4.206 billion for the 1^st quarter of 2011.

Total investments, including money market accounts, totaled $2.989 billion at June 30, 2011, a slight increase of $7.3 million compared to $2.982 billion at March 31, 2011.

Higher priced other time deposits declined $73.4 million in the 2^nd quarter.

Old National reported net interest income of $62.3 million for 2^nd quarter 2011 compared to $61.4 million in 1^st quarter 2011, and $55.2 million for 2^nd quarter 2010.

Net interest income on a fully taxable equivalent basis was $65.2 million for 2^nd quarter 2011 and represented a net interest margin on total average earning assets of 3.67%. This compares to net interest income on a fully taxable equivalent basis of $64.4 million and a margin of 3.62% in 1^st quarter 2011 and net interest income on a fully taxable equivalent basis of $58.6 million and a margin of 3.40% for 2^nd quarter 2010.
