Transaction Rationale

Opportunistic acquisition in markets similar to ours at a compelling price

Achieving growth through acquisition does NOT mean that our core organic growth strategy is slowing or becoming less effective

Multiples of 119% of TBV and 11.5x LTM earnings attractive as compared to comparable transactions. Our strong “currency” creates favorable outcome

FC Banc Corp. high-performing with ROA of 1.0% and ROE of 10.8% for 2012

Provides new avenues for growth without the cut-throat pricing and deal structures more traditionally seen in metropolitan markets

Additional capital and broader product and service expertise could lead to significant growth in these new markets without additional M&A deals

Local bankers with a deep history and understanding of these markets is critical

Acquiring commercial real estate and agricultural lending expertise to complement our strong C&I business lending background

Ability to replicate our successful ERIEBANK model using a distinct brand with local bankers and oversight to serve particular markets
