CVB Financial Corp. CFO Postpones Retirement

Ontario, California, August 12, 2010- CVB Financial Corp. (NASDAQ:CVBF) announced that Edward J. Biebrich, Jr, Chief Financial Officer, has postponed his retirement in order to assist the Company in responding to the Securities and Exchange Commission inquiry.

This is strictly a coincidence and my retirement is not caused by the subpoena,” said Mr. Biebrich. “I have been contemplating retiring for a while and started building a retirement house in March of this year. However, I now plan to continue in my role as CFO.”
