          Information.*

*    Information required by Part I to be contained in the

     PART II

     INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

Item 3.   Incorporation of Certain Documents by Reference.

          The following documents filed by Registrant with the
Securities and Exchange Commission are incorporated by reference in this
Registration Statement:

          (1)  The Registrant's Annual Report on Form 10-K for the

          (2)  The information with regard to the Registrant's capital

Item 4.   Description of Securities.

          Not applicable.
<PAGE>

Item 5.   Interests of Named Experts and Counsel.

          Not applicable.

Item 6.   Indemnification of Directors and Officers.

     Section 317 of the California Corporations Code authorizes a court
to award, or a corporation's Board of Directors to grant, indemnity to
directors, officers, employees and other agents of the corporation
("Agents") in terms sufficiently broad to permit such indemnification
under certain circumstances for liabilities (including reimbursement for
expenses incurred) arising under the Securities Act of 1933, as amended
(the "Act").

     Article VII of the Company's Restated Articles of Incorporation, as
amended (Exhibit 4.1 hereto) authorizes the Company to indemnify its
Agents, through bylaw provisions, agreements, votes of shareholders or
disinterested directors or otherwise, in excess of the indemnification
otherwise permitted by Section 317 of the California Corporations Code,
subject to the applicable limits set forth in Section 204 of the
California Corporations Code with respect to actions for breach of duty
to the Company and its shareholders.  Article VII also authorizes the
Company to provide insurance for Agents provided that, in cases where
the Company owns all or a portion of the shares of the company issuing
the insurance policy, such company and/or the policy must meet certain
conditions set forth in Section 317.  Article V of the Company's Bylaws
provides for mandatory indemnification of each director of the Company
except as prohibited by law.

     The Company maintains a directors and officers liability insurance
policy that indemnifies the Company's directors and officers against
certain losses in connection with claims made against them for certain
wrongful acts.  In addition, the Company has entered into separate
indemnification agreements with its directors and officers that require
the Company, among other things, (i) to maintain directors' and
officers' insurance in reasonable amounts in favor of such individuals,
and (ii) to indemnify them against certain liabilities that may arise by
reason of their status or service as Agents of the Company to the
fullest extent permitted by California law.

Item 7.   Exemption from Registration Claimed.

          Not applicable.

Item 8.   Exhibits.

          See Index to Exhibits.
<PAGE>
Item 9.   Undertakings.

          (a)  The undersigned Registrant hereby undertakes:

          (1)  To file, during any period in which offers or sales are
being made, a post-effective amendment to this Registration Statement:

               (i)  To include any prospectus required by section
10(a)(3) of the Securities Act of 1933;

               (ii)  To reflect in the prospectus any facts or events
arising after the effective date of the Registration Statement (or the
most recent post- effective amendment thereof) which, individually or in
the aggregate, represent a fundamental change in the information set
forth in the Registration Statement;

               (iii)  To include any material information with respect
to the plan of distribution not previously disclosed in the Registration
Statement or any material change to such information in the
Registration Statement;

     provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not
apply if the Registration Statement is on Form S-3 or Form S-8, and the
information required to be included in a post-effective amendment by
those paragraphs is contained in periodic reports filed by the
Registrant pursuant to section 13 or section 15(d) of the Securities
Exchange Act of 1934 that are incorporated by reference in the
Registration Statement.

          (2)  That, for the purpose of determining any liability under
the Securities Act of 1933, each such post-effective amendment shall be
deemed to be a new Registration Statement relating to the securities
offered therein, and the offering of such securities at that time shall
be deemed to be the initial bona fide offering thereof.

          (3)  To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at
the termination of the offering.

          (b)  The undersigned Registrant hereby further undertakes
that, for purposes of determining any liability under the Securities Act
of 1933, each filing of the Registrant's annual report pursuant to
section 13(a) or section 15(d) of the Securities Exchange Act of 1934
that is incorporated by reference in the Registration Statement shall be
deemed to be a new Registration Statement relating to the securities
offered therein, and the offering of such securities at that time shall
be deemed to be the initial bona fide offering thereof.
<PAGE>
          (c)  Insofar as indemnification for liabilities arising under
the Securities Act of 1933 may be permitted to directors, officers and
controlling persons of the Registrant pursuant to the foregoing
provisions, or otherwise, the Registrant has been advised that in the
opinion of the Securities and Exchange Commission such indemnification
is against public policy as expressed in the Act and is, therefore,
unenforceable.  In the event that a claim for indemnification against
such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the
Registrant in the successful defense of any action, suit or proceeding)
is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will,
unless in the opinion of its counsel the matter has been settled by
controlling precedent, submit to a court of appropriate jurisdiction the
question whether such indemnification by it is against public policy as
expressed in the Act and will be governed by the final adjudication of
such issue.

     With reference to the Registration Statement on Form S-8 to be

the Common Stock of the Company, when issued and sold in accordance with
the respective plans, will be legally issued, fully paid and
nonassessable.

     We hereby consent to the filing of this opinion with the 
Securities and Exchange Commission as Exhibit 5.1 to the Registration

otherwise permitted by Section 317 of the California Corporations Code,
subject to the applicable limits set forth in Section 204 of the
California Corporations Code with respect to actions for breach of duty
to the Company and its shareholders.  Article VII also authorizes the
Company to provide insurance for Agents provided that, in cases where
the Company owns all or a portion of the shares of the company issuing
the insurance policy, such company and/or the policy must meet certain
conditions set forth in Section 317.  Article V of the Company's Bylaws
provides for mandatory indemnification of each director of the Company
except as prohibited by law.

     The Company maintains a directors and officers liability insurance
policy that indemnifies the Company's directors and officers against
certain losses in connection with claims made against them for certain
wrongful acts.  In addition, the Company has entered into separate
indemnification agreements with its directors and officers that require
the Company, among other things, (i) to maintain directors' and
officers' insurance in reasonable amounts in favor of such individuals,
and (ii) to indemnify them against certain liabilities that may arise by
reason of their status or service as Agents of the Company to the
fullest extent permitted by California law.

Item 7.   Exemption from Registration Claimed.

          Not applicable.

Item 8.   Exhibits.

          See Index to Exhibits.
Item 9.   Undertakings.

          (a)  The undersigned Registrant hereby undertakes:

          (1)  To file, during any period in which offers or sales are
being made, a post-effective amendment to this Registration Statement:

               (i)  To include any prospectus required by section
10(a)(3) of the Securities Act of 1933;

               (ii)  To reflect in the prospectus any facts or events
arising after the effective date of the Registration Statement (or the
most recent post- effective amendment thereof) which, individually or in
the aggregate, represent a fundamental change in the information set
forth in the Registration Statement;

               (iii)  To include any material information with respect
to the plan of distribution not previously disclosed in the Registration
Statement or any material change to such information in the
Registration Statement;

     provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not
apply if the Registration Statement is on Form S-3 or Form S-8, and the
information required to be included in a post-effective amendment by
those paragraphs is contained in periodic reports filed by the
Registrant pursuant to section 13 or section 15(d) of the Securities
Exchange Act of 1934 that are incorporated by reference in the
Registration Statement.

          (2)  That, for the purpose of determining any liability under
the Securities Act of 1933, each such post-effective amendment shall be
deemed to be a new Registration Statement relating to the securities
offered therein, and the offering of such securities at that time shall
be deemed to be the initial bona fide offering thereof.

          (3)  To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at
the termination of the offering.

          (b)  The undersigned Registrant hereby further undertakes
that, for purposes of determining any liability under the Securities Act
of 1933, each filing of the Registrant's annual report pursuant to
section 13(a) or section 15(d) of the Securities Exchange Act of 1934
that is incorporated by reference in the Registration Statement shall be
deemed to be a new Registration Statement relating to the securities
offered therein, and the offering of such securities at that time shall
be deemed to be the initial bona fide offering thereof.
(c)  Insofar as indemnification for liabilities arising under
the Securities Act of 1933 may be permitted to directors, officers and
controlling persons of the Registrant pursuant to the foregoing
provisions, or otherwise, the Registrant has been advised that in the
opinion of the Securities and Exchange Commission such indemnification
is against public policy as expressed in the Act and is, therefore,
unenforceable.  In the event that a claim for indemnification against
such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the
Registrant in the successful defense of any action, suit or proceeding)
is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will,
unless in the opinion of its counsel the matter has been settled by
controlling precedent, submit to a court of appropriate jurisdiction the
question whether such indemnification by it is against public policy as
expressed in the Act and will be governed by the final adjudication of
such issue.

          Pursuant to the requirements of the Securities Act of 1933,

undersigned, thereunto duly authorized, in the City of San Rafael, State
of California, on January 26, 1995.

     Re:  Registration Statement on Form S-8

Ladies and Gentlemen:

     With reference to the Registration Statement on Form S-8 to be
filed by Westamerica Bancorporation, a California corporation (the
"Company"), with the Securities and Exchange Commission under the
Securities Act of 1933, relating to 182,618 shares of the Company's
Common Stock issuable pursuant to the PV Financial 1992 Employee Stock
Option Plan, PV Financial 1991 Director Stock Option Plan and PV
Financial 1982 Stock Option Plan, it is our opinion that such shares of
the Common Stock of the Company, when issued and sold in accordance with
the respective plans, will be legally issued, fully paid and
nonassessable.

     We hereby consent to the filing of this opinion with the 
Securities and Exchange Commission as Exhibit 5.1 to the Registration
Statement.

          Very truly yours,

1992 and 1991 restated consolidated totals, were audited by other auditors.
Our report, insofar as it relates to the amounts included for Napa Valley
Bancorp, is based solely on the report of the other auditors.
