Summary of RIVER VALLEY BANCORP

Entry into a Material Definitive Agreement, Financial Statements and Exhibit

Item 1.01 Entry into a Material Definitive Agreement

Effective as of July 31, 2012, River Valley Bancorp (the "Registrant"), Citizens Union Bancorp of Shelbyville, Inc. ("Citizens"), River Valley Financial Bank ("River"), and Dupont State Bank ("Dupont") entered into an amendment (the "Amendment") to its previously announced Reorganization Agreement among Registrant, Citizens, River and Dupont dated December 5, 2011, as previously amended on May 31, 2012 and on June 29, 2012 (the "Agreement"). Under the Agreement, River Valley Financial Bank ("River"), a wholly-owned subsidiary of Registrant, will merge (the "Merger") with Dupont ("Dupont"), an Indiana commercial bank and wholly-owned subsidiary of Citizens. The surviving entity which will be an Indiana commercial bank named River Valley Financial Bank, will be wholly owned by Registrant from and after the closing.

The Agreement had provided that any of the parties, for various reasons, could terminate the Agreement if the Merger had not closed (the "Closing") by July 31, 2012. The Indiana Department of Financial Institutions has approved the Merger, but the parties have not yet received the approvals of the Federal Deposit Insurance Corporation or the Board of Governors of the Federal Reserve System of the Merger transaction and associated charter flip of River. There is a 15-day waiting period following such approvals before the parties can close the Merger. As a result, the parties have agreed to extend the deadline for closing the Merger from July 31, 2012 to November 9, 2012. The parties currently expect to receive these regulatory approvals in time to close the transaction on September 28, 2012, but if that does not occur, they will close the transaction as soon as possible after the receipt of those regulatory approvals.

In addition, Citizens has agreed to continue providing data processing services to Dupont under its master contract between the date of closing of the Merger and the date River's data processor can complete its conversion of Dupont's customers to River's data processing system. Those post-closing services are to be provided pursuant to a data processing agreement to be negotiated and agreed to by Citizens and Dupont, but the parties have agreed to a monthly fee of $10,000 for such services, plus direct pass-through costs and expenses for core processing, internet banking, and communication technologies pertaining to Dupont's operations. In addition, at the time of signing the data processing agreement, River has agreed to pay Citizens a one-time fee equal to the lesser of (i) an amount equal to $65,000 or (ii) the net income of Dupont from August 1, 2012, to the Closing date (increased by any legal costs of Dupont relating to the Merger from and after August 1, 2012, and excluding any accruals, reserves or charges taken by Dupont at the request of River).

The Agreement has also been amended to permit Registrant and River to perform an updated due diligence investigation of Dupont focusing on its loan portfolio and earnings. That investigation is to be completed by September 28, 2012. If that investigation suggests that Dupont's financial condition and operating results have materially deteriorated since the date of execution of the Agreement in a manner not reasonably acceptable to Registrant or River, Registrant and River may terminate the Agreement within 15 days after completion of such investigation.

A copy of the Amendment is attached hereto as Exhibit 2.1 and incorporated by reference herein.
