Item 8.01 Other Events.

On October 25, 2005 Pacific Capital Bancorp (the "Company") issued a press
release announcing its financial results for the quarter and the nine months
ended October 25, 2005. A copy of the press release, including unaudited
financial information released as a part thereof, is included as Exhibit 99.1 to
this Current Report on Form 8-K and is incorporated herein by reference. The
Company will include detailed financial statements and additional analyses for
the quarterly period ended October 25, 2005, as part of its Form 10-Q covering
that period.

     The press release contains financial information determined by methods
other than in accordance with Generally Accepted Accounting Principles ("GAAP")
for the United States. Management uses these non-GAAP measures in their analysis
of the business and its performance. In particular, net interest income, net
interest margin and operating efficiency are calculated on a fully
tax-equivalent basis ("FTE") and the Company has amounts and ratios computed by
excluding the assets, liabilities, and results of operation for the Company
refund loan and transfer programs.

     Management believes that the measures calculated on a FTE basis provide a
useful picture of net interest income, net interest margin and operating
efficiency for comparative purposes. Net interest income and net interest margin
on a FTE basis is determined by adjusting net interest income to reflect
tax-exempt interest income on an equivalent before-tax basis. The efficiency
ratio also uses net interest income on a FTE basis.

     The assets, liabilities, and results of operations of the Company's refund
programs are reported in its periodic filings with the SEC as a segment of its
business. Because these are unusual activities, users of the financial
statements have indicated that they are interested in information for the
Company exclusive of these programs so that they may compare the results of
operations with financial institutions that have no comparable programs. The
amounts and ratios may generally be computed from the information provided in
the note to its financial statements that discloses segment information, but are
computed and included in the press release for the convenience of those users.

     Non-GAAP information presented by other companies may not be comparable to
that presented herein, since each company may define non-GAAP measures
differently.
