Union Bank of California:

WHAT:   Keitaro Matsuda, senior economist for Union Bank of
        California, today released his June 2007 Economic Report
        focusing on the California economy. The report, titled "Jobs
        in California: Why the Statewide Statistics May Not Tell the
        Whole Story," is part of a monthly series produced by Matsuda
        on the California, Pacific Northwest and U.S. economies.

WHY:    The June 2007 report discusses economic factors at play in
        California and various regions in the state, including:

            -- Slowing statewide growth in payroll employment and
               growing unemployment

            -- Strength in service and government sectors, but
               deceleration in construction and financial industries

            -- Tech-sector recovery in San Francisco Bay Area,
               contrasted with slowdowns in the Los Angeles Basin and
               San Diego County

            -- Loss of momentum in the Central Valley, particularly in
               the northern counties

WHO:    Keitaro Matsuda has served as senior economist for Union Bank
        of California since 1997. He monitors economic trends and
        developments for Union Bank management and customers. Matsuda
        is also a member of the economic advisory committee of the
        American Bankers Association. Union Bank of California, the
        wholly owned subsidiary of UnionBanCal Corporation (NYSE: UB),
