(4.3%) from $493,444,000 as of September 30, 2006. Since December 31, 2006,

At September 30, 2007, the allowance for loan and lease losses totaled

Contributing to the increase during the third quarter were three loans that
totaled $2,761,000 (89.1% of the total). The first of these loans had a balance
of $1,328,000 and is a development loan for residential lots; the second loan
had a balance of $1,111,000 and is a real estate loan on a multi-tenant office
building; and the third loan, in the amount of $322,000, is secured by a
seven-acre parcel in a rural part of Sacramento County. Management believes that
all three of these loans are adequately secured and adequately reserved. The
remaining balance of the nonperforming loans and leases totaled $339,000 and
represented 11 accounts, mainly small dollar leases. Subsequent to quarter end
one of the 11 small dollar-nonperforming assets was acquired in a foreclosure
sale. The carrying value of this real estate owned property represents $57,000.

"Although nonperforming assets ended the quarter at just over $3 million, the
total represents less than 1% of total loans," continued Taber. "Our
high-quality credit culture remains intact and executive management is actively
managing our nonperforming assets."
