CVB Financial Corp. and Valley Commerce Bancorp Announce Amended Merger Agreement

Ontario, CA and Visalia, CA, December 20, 2016 - CVB Financial Corp. (NASDAQ: CVBF) and Valley Commerce Bancorp (OTC PINK: VCBP) announced today that they have amended the merger agreement, pursuant to which CVB Financial Corp. (“CVBF”) will acquire Valley Commerce Bancorp (“VCBP”) the holding company for Valley Business Bank.

Pursuant to the amendment, the aggregate number of shares of CVB Financial common stock that VCBP’s shareholders may receive in the merger is fixed at 1,942,673, but is now subject to a pricing collar requiring the aggregate merger consideration to have a value of not less than approximately $50.6 million and not more than approximately $62.2 million depending on the average closing price of CVB Financial’s common stock prior to the closing of the merger and subject to adjustment for VCBP’s merger-related transaction expenses.

In particular, the amendment provides that if the weighted average closing price of CVB’s common stock before the merger is $20.00 or greater, the aggregate number of shares of CVB common stock that VCBP holders will receive will be reduced so that the aggregate merger consideration will not exceed $62.2 million. Similarly, the amendment provides that if the average closing price of CVB common stock is less than $14.00, then CVB, in its discretion, will either increase the number of shares of CVB common stock included in the aggregate stock consideration, increase the cash included in the aggregate cash consideration, or some combination of these so that the aggregate merger consideration is not less than $50.6 million. In each case, the aggregate merger consideration is subject to further adjustment based for VCBP’s merger-related transaction expenses.

The amendment also, among other items, allows CVB to terminate the merger agreement in the event its average closing price is less than $11.00 and removes, as a condition to closing, the requirement that VCBP’s transaction related expenses not exceed certain thresholds.

The parties continue to expect the merger to close during the first quarter of 2017.
