MUNCIE, Ind. and MUNSTER, Ind. — First Merchants Corporation (NASDAQ: FRME) and CFS Bancorp, Inc. (NASDAQ: CITZ) today announced they have executed a definitive agreement whereby CFS will merge with and into First Merchants, and its wholly-owned bank subsidiary, Citizens Financial Bank, will merge with and into First Merchants Bank, NA.

The merger agreement provides that shareholders of CFS will have the right to receive 0.65 shares of First Merchants common stock for each share of CFS common stock owned.  Based on the closing price of First Merchants’ common stock on May 10, 2013 of $16.14, the transaction value is approximately $114.7 million, with an implied price per share of CFS common stock of $10.49.

The transaction is expected to be completed in the fourth quarter of 2013, subject to the affirmative vote of CFS and First Merchants shareholders, regulatory approvals, and other customary conditions.  The combined company, doing business as First Merchants Bank expects to complete its integration during the first quarter of 2014.

First Merchants and CFS will have combined assets of $5.4 billion and create the second largest financial holding company headquartered in Indiana. The combined company will have nearly 100 banking offices in twenty-six Indiana counties, as well as two counties in both Ohio and Illinois.

Michael C. Rechin, President and Chief Executive Officer of First Merchants, said, “Like First Merchants, Citizens has a long history of deep-rooted commitment to community banking and we are excited that it will become the newest member of the First Merchants family.  We believe that our strategy to be a service-driven alternative to our super-regional bank competitors will support the acceleration of the Citizens’ current initiatives while furthering our goal of becoming a more efficient higher performing company.  The Citizens franchise is a logical geographic extension for us given the 20-mile proximity of our nearest branch locations.  Citizens’ markets in Northwest Indiana, and specifically Valparaiso, Merrillville, Schererville, Crown Point and Munster, are very similar to Lafayette, Plainfield and Greenwood Indiana markets.  We believe our partnership will provide our business and consumer customers with broader services, greater access and expanded product offerings, while maintaining our legacy of local community banking.

“We expect this combination to be mutually beneficial to First Merchants and CFS’s shareholders.  We anticipate earnings per share accretion in 2014 and beyond through identified operating efficiencies of approximately thirty percent resulting in tangible book value earnback of less than three years,” Rechin added.

Daryl D. Pomranke, Citizens’ Chief Executive Officer and President, and Dale S. Clapp, Citizens’ Executive Vice President – Sales Management, will be executives in First Merchants Banks’ newly acquired market, with Mr. Pomranke to serve as Regional President.

Mr. Pomranke stated, “We are excited about the opportunity to become part of the First Merchants family, and believe this partnership will be good for our clients, shareholders and communities.  For several years now, our executive management team, including our CFO Jerry Weberling, and Dale Clapp has been driven to be the community bank of choice in our marketplace.  Our bankers look forward to taking advantage of new product capabilities and continuing to build momentum with our clients as First Merchants. The core values of both companies share a commitment to local decision making, personal service, long-term relationships and community involvement.”
