     The transactions will introduce the Bank of the West “bear” brand into 10 new states — Arizona, Colorado, Iowa, Minnesota, Nebraska, North Dakota, South Dakota, Utah, Wisconsin and Wyoming – and add to the bank’s presence in San Joaquin and Stanislaus Counties in California’s Central Valley. Following the acquisitions, BancWest will have approximately $49 billion in assets and more than 530 branches in 17 Western and Midwestern states, Guam and Saipan.

     “Although the signs on the door will change, Community First and Union Safe Deposit customers will receive the same personal service that they’re used to, because that’s been a Bank of the West tradition for 130 years,” said Don J. McGrath, President of BancWest and Chief Executive officer of Bank of the West.

     “These acquisitions make BancWest one of the premier financial services franchises in the Western United States. These are two complementary banks that fit in well with BancWest both strategically and financially,” said Walter A. Dods, Jr. Chairman and Chief Executive Officer of BancWest.
