Pursuant to the terms and conditions set forth in the Merger Agreement, each outstanding share of First California common stock was converted into the right to receive 0.2966 of a share of the common stock of the Company (the "
Exchange Ratio
").  Holders of First California's Series A Convertible Perpetual Preferred Stock converted their shares of preferred stock into shares of First California common stock prior to the Merger.  Each outstanding option to purchase a share of First California common stock became fully vested and, immediately after the Effective Time, was cancelled and the holder became entitled to receive an amount per share in cash, without interest, equal to the excess if any of $8.00 less the exercise price.  Each share of restricted stock became fully vested and was converted into the right to receive a number of shares of outstanding common stock of the Company equal to the Exchange Ratio.  Each share of the Company's common stock remained outstanding and was unaffected by the Merger.
Immediately prior to the Merger, First California redeemed all outstanding shares of its Non-Cumulative Perpetual Preferred Stock, Series C, from the United States Department of the Treasury for $25,146,379.45 in cash.
Simultaneously with the closing of the Merger, First California Bank, a wholly-owned bank subsidiary of First California, merged with and into Pacific Western Bank, a wholly-owned bank subsidiary of the Company, with Pacific Western Bank continuing as the surviving bank.
