WALNUT CREEK, CA, AND IRVINE, CA, April 28, 2016 – Mechanics Bank (“Mechanics”) and California Republic Bancorp (“CRB”) (OTCBB: CRPB), a bank holding company for California Republic Bank, today announced that they have reached a definitive agreement to merge. The transaction has been approved by the Boards of Directors of each company. Under the terms of the agreement, CRB shareholders will receive $37.19 per share in cash.

Headquartered in Irvine, CRB is a commercial and private lending institution with approximately 500 employees and five regional commercial banking locations throughout Southern California. As of March 31, 2016, CRB had approximately $1.8 billion in total assets. CRB also operates a significant auto lending division across 14 states. The combined entity would have approximately $5.4 billion in total assets.

“We think California Republic Bank is the perfect complement for Mechanics Bank,” said Ken Russell, President and CEO of Mechanics Bank. “Mechanics Bank has plenty of capital and capacity, and CRB is an extraordinarily effective and efficient asset generator. We both are committed to a very personal and high-touch, relationship-based form of banking, and both banks fill niches that big banks can’t.”

John DeCero, President of California Republic Bancorp, commented, “We believe the future prospects of these two outstanding organizations as a combined entity are tremendous. There’s very little overlap between the two institutions and many synergies.”

Completion of the transaction is subject to customary closing conditions, including the receipt of required regulatory and shareholder approvals. The transaction is expected to close in the second half of 2016. Clients of both banks should continue to do business with their current bankers, and expect little to change as the two organizations are brought together.

Keefe, Bruyette & Woods, Inc. acted as financial advisor to CRB, and Sheppard, Mullin, Richter & Hampton LLP acted as legal advisor. Wachtell, Lipton, Rosen & Katz acted as legal advisor to Mechanics.
