     /1/   Estimated pursuant to Rule 457 solely for purposes of calculating the
registration fee.  As to shares subject to outstanding but unexercised options
under the Cupertino National Bancorp 1995 Stock Option Plan, the price is
computed on the basis of the exercise price.  As to shares under the Cupertino
National Bancorp Employee Stock Purchase Plan, this plan establishes a purchase
price equal to 85% of the fair market value of the Company's Common Stock and,
therefore, the price for purchase rights under this plan is based upon 85% of 
the average of the high and low prices of the Common Stock on September 1 1995,
as reported on the National Association of Securities Dealers Automated 
Quotations System. As to the remaining shares the price is based upon the 
average of the high and low prices of the Common Stock on September 1, 1995, as
reported on the National Association of Securities Dealers Automated Quotations
System.

              INFORMATION REQUIRED IN THE REGISTRATION STATEMENT
              --------------------------------------------------


Item 3.   Incorporation of Documents by Reference
------    ---------------------------------------

          Cupertino National Bancorp (the "Company") hereby incorporates by
reference in this registration statement the following documents:

          (a)    The Company's latest annual report on Form 10-K filed pursuant
to Sections 13(a) or 15(d) of the Securities Exchange Act of 1934, as amended
(the "Exchange Act"), containing audited financial statements for the Company's
latest fiscal year ended December 31, 1994 as filed with the Commission on March
31, 1995.

          (b)    All other reports filed pursuant to Section 13(a) or 15(d) of
the Exchange Act since the end of the fiscal year covered by the registrant
document referred to in (a) above.

          (c)    The description of the Company's Common Stock contained in the
Company's Registration Statement on Form 8-A filed under the Exchange Act,
including any amendment or report filed for the purpose of updating such
description.

          All documents subsequently filed by the Company pursuant to Sections
13(a), 13(c), 14 and 15(d) of the Exchange Act, prior to the filing of a post-
effective amendment to this registration statement which indicates that all
securities offered hereby have been sold or which deregisters all securities
remaining unsold, shall be deemed to be incorporated by reference in this
registration statement and to be a part hereof from the date of filing of such
documents.

Item 4.   Description of Securities
------    -------------------------

          The class of securities to be offered is registered under Section 12

Item 6.   Indemnification of Directors and Officers
------    -----------------------------------------

          The Company's Articles of Incorporation provide that the liability of
the directors for monetary damages shall be eliminated to the fullest extent
permissible under California law.  Pursuant to California law, the Company's
directors shall not be liable for monetary damages for breach of the directors'
fiduciary duty of care to the Company and its shareholders.  However, this
provision does not eliminate the duty of care, and in appropriate circumstances,
equitable remedies such as injunctive or other forms of non-monetary relief will
remain available under California law.  In addition, each director will continue
to be subject to liability for (i) acts or omissions that involve intentional
misconduct or a knowing and culpable violation of law, (ii) acts or omissions
that a director believes to be contrary to the best interests of the Company or
its shareholders or that involve the absence of good faith on the part of the
director, (iii) any transaction from which a director derived an improper
personal benefit, (iv) acts or omissions that show a reckless disregard for the
director's duty to the Company or its shareholders in circumstances in which the
director was aware, or should have been aware, in the ordinary course of
performing a director's duties, of a risk of serious injury to the Company or
its shareholders, (v) acts or omissions that constitute an unexcused pattern of
inattention that amounts to an abdication of the director's duty to the Company
or its shareholders, (vi) any transaction that constitutes an illegal
distribution or dividend under California law, and (vii) any transaction
involving an unlawful conflict of interest between the director and the Company
under California law.  The provision also does not affect a director's
responsibilities under any other law, such as the federal securities laws or
state or federal environmental laws.

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

                                       4

                (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)(l)(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 Exchange Act 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)  Filing incorporating subsequent Exchange Act documents by reference
          -------------------------------------------------------------------

          The undersigned registrant hereby 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
Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section 15(d) of the Exchange Act) 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.

     (h)  Request for acceleration of effective date or filing of registration
          --------------------------------------------------------------------
          statement on Form S-8
          ---------------------

          Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the 

                                       5
<PAGE>
 
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.

________________________

     /1/   Estimated pursuant to Rule 457 solely for purposes of calculating the
registration fee.  As to shares subject to outstanding but unexercised options
under the Cupertino National Bancorp 1995 Stock Option Plan, the price is
computed on the basis of the exercise price.  As to shares under the Cupertino
National Bancorp Employee Stock Purchase Plan, this plan establishes a purchase
price equal to 85% of the fair market value of the Company's Common Stock and,
therefore, the price for purchase rights under this plan is based upon 85% of 
the average of the high and low prices of the Common Stock on September 1 1995,
as reported on the National Association of Securities Dealers Automated 
Quotations System. As to the remaining shares the price is based upon the 
average of the high and low prices of the Common Stock on September 1, 1995, as
reported on the National Association of Securities Dealers Automated Quotations
System.

PART II

              INFORMATION REQUIRED IN THE REGISTRATION STATEMENT
              --------------------------------------------------

Item 3.   Incorporation of Documents by Reference
------    ---------------------------------------

          Cupertino National Bancorp (the "Company") hereby incorporates by
reference in this registration statement the following documents:

          (a)    The Company's latest annual report on Form 10-K filed pursuant
to Sections 13(a) or 15(d) of the Securities Exchange Act of 1934, as amended
(the "Exchange Act"), containing audited financial statements for the Company's
latest fiscal year ended December 31, 1994 as filed with the Commission on March
31, 1995.

          (b)    All other reports filed pursuant to Section 13(a) or 15(d) of
the Exchange Act since the end of the fiscal year covered by the registrant
document referred to in (a) above.

          (c)    The description of the Company's Common Stock contained in the
Company's Registration Statement on Form 8-A filed under the Exchange Act,
including any amendment or report filed for the purpose of updating such
description.

          All documents subsequently filed by the Company pursuant to Sections
13(a), 13(c), 14 and 15(d) of the Exchange Act, prior to the filing of a post-
effective amendment to this registration statement which indicates that all
securities offered hereby have been sold or which deregisters all securities
remaining unsold, shall be deemed to be incorporated by reference in this
registration statement and to be a part hereof from the date of filing of such
documents.

Item 4.   Description of Securities
------    -------------------------

          The class of securities to be offered is registered under Section 12
of the Exchange Act.

Item 5.   Interests of Named Experts and Counsel
------    --------------------------------------

          Inapplicable.

                                       3
Item 6.   Indemnification of Directors and Officers
------    -----------------------------------------

          The Company's Articles of Incorporation provide that the liability of
the directors for monetary damages shall be eliminated to the fullest extent
permissible under California law.  Pursuant to California law, the Company's
directors shall not be liable for monetary damages for breach of the directors'
fiduciary duty of care to the Company and its shareholders.  However, this
provision does not eliminate the duty of care, and in appropriate circumstances,
equitable remedies such as injunctive or other forms of non-monetary relief will
remain available under California law.  In addition, each director will continue
to be subject to liability for (i) acts or omissions that involve intentional
misconduct or a knowing and culpable violation of law, (ii) acts or omissions
that a director believes to be contrary to the best interests of the Company or
its shareholders or that involve the absence of good faith on the part of the
director, (iii) any transaction from which a director derived an improper
personal benefit, (iv) acts or omissions that show a reckless disregard for the
director's duty to the Company or its shareholders in circumstances in which the
director was aware, or should have been aware, in the ordinary course of
performing a director's duties, of a risk of serious injury to the Company or
its shareholders, (v) acts or omissions that constitute an unexcused pattern of
inattention that amounts to an abdication of the director's duty to the Company
or its shareholders, (vi) any transaction that constitutes an illegal
distribution or dividend under California law, and (vii) any transaction
involving an unlawful conflict of interest between the director and the Company
under California law.  The provision also does not affect a director's
responsibilities under any other law, such as the federal securities laws or
state or federal environmental laws.

Item 7.   Exemption From Registration Claimed
------    -----------------------------------

          Inapplicable.

------    ------------

          (a)   Rule 415 Offering
                -----------------

          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:

                                       4
(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)(l)(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 Exchange Act 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)  Filing incorporating subsequent Exchange Act documents by reference
          -------------------------------------------------------------------

          The undersigned registrant hereby 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
Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section 15(d) of the Exchange Act) 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.

     (h)  Request for acceleration of effective date or filing of registration
          --------------------------------------------------------------------
          statement on Form S-8
          ---------------------

          Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the 

                                       5
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.

                                   SIGNATURE
                                   ---------

     Pursuant to the requirements of the Securities Act of 1933, as amended, the
registrant certifies that it has reasonable grounds to believe that it meets all
of the requirements for filing on Form S-8 and has duly caused this registration
statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in the City of Cupertino, State of California, on August 17, 1995.
