     Item 5.  Other Events.

     This Current Report on Form 8-K contains selected information concerning
CapitolBank Sacramento, a California state-chartered bank ("Capitol").  This
information is supplied in connection with the proposed acquisition of Capitol
(the "Merger") by registrant Westamerica Bancorporation ("Westamerica").
Westamerica will file a Registration Statement on Form S-4 (the "Registration
Statement") under the Securities Act of 1933 relating to the shares of
Westamerica common stock to be issued in connection with the Merger, and such
Registration Statement will incorporate by reference the information contained
herein.

       Capitol is subject to the informational requirements of the Securities
Exchange Act of 1934 as administered by the Federal Deposit Insurance
Corporation (the "FDIC") and, in accordance therewith, files reports, proxy
statements and other information with the FDIC, to which reference is made for
detailed financial and other information regarding Capitol.  Such reports, proxy
statements and other information can be inspected and copies obtained from the
Registration and Disclosure Section of the FDIC, 1776 F Street N.W., Room 643,
Washington, D.C. 20459, at prescribed rates.  These documents may also be
inspected at the Federal Reserve Bank of San Francisco, 101 Market Street, San
Francisco, California 94105. Although Westamerica has no reason to believe the
information concerning Capitol included herein is not reliable, it has not
verified either its accuracy or its completeness.  Westamerica does not warrant
that there have not occurred events, not yet publicly disclosed by Capitol,
which would affect either the accuracy or the completeness of the information
concerning Capitol included herein.  Westamerica has no affiliation with Capitol
other than the proposed acquisition of Capitol by Westamerica pursuant to an
Agreement and Plan of Reorganization, dated as of November 17, 1994.  The FDIC
does not approve or disapprove or pass upon the accuracy or the adequacy of
reports, proxy statements or other information filed with it.
