Item 2.01. Completion of Acquisition or Disposition of Assets.

On August 29, 2008, MainSource Financial Group, Inc., an Indiana corporation ("MainSource"), completed its previously announced acquisition of 1st Independence Financial Group, Inc., a Delaware corporation ("1st Independence"), pursuant to an Agreement and Plan of Merger (the "Merger Agreement") by and among MainSource, 1st Independence and 1st Independence Bank, Inc., a Kentucky chartered commercial bank and a wholly owned subsidiary of 1st Independence ("1st Bank"). Pursuant to the terms of the Merger Agreement, which was approved by the stockholders of 1st Independence on August 7, 2008, 1st Independence was merged with and into MainSource, with MainSource being the surviving corporation (the "Merger"). As a result of the Merger, 1st Bank became a wholly owned subsidiary of MainSource.

In connection with the Merger, 1st Independence stockholders will receive cash in the amount of $4.418 per share and 0.7849 shares of MainSource common stock for each share of 1st Independence common stock owned by them, subject to the terms of the Merger Agreement. Any fractional shares of MainSource common stock resulting from the foregoing calculation will be replaced by cash in the amount of such fraction multiplied by $18.52. Holders of options to purchase 1st Independence common stock will receive an amount of cash equal to $18.954, less the per share exercise price for each share of 1st Independence common stock subject to such stock option. If the foregoing calculation results in a negative number, the 1st Independence stock option will be canceled without any cash payment.

MainSource will issue approximately a total of 1,569,800 shares of MainSource common stock and pay a total of $8,836,000 in cash to former 1st Independence stockholders.

The description of the Merger Agreement is qualified in its entirety by reference to the Merger Agreement, incorporated as an exhibit hereto. A copy of the MainSource press release dated September 2, 2008 announcing the completion of the Merger is attached hereto as Exhibit 99.1 and is incorporated herein by reference.
