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

          The following documents which have been filed with the Securities and
Exchange Commission are incorporated by reference as of their respective dates
and are a part hereof:

          (a) The Company's Annual Report on Form 10-K for the year ended
December 31, 2000;

          (b) The Company's Quarterly Report on Form 10-Q for the quarter ended
March 31, 2001;

          (c) The description of the Common Stock contained in the Company's
Registration Statement on Form 8-A and in any amendment or report filed for the
purpose of amending such description.

          Additionally, all documents subsequently filed by the Company pursuant
to Sections 13(a), 13(c), 14 and 15(d) of the Securities Exchange Act of 1934,
as amended, prior to the filing of a post-effective amendment hereto which
indicates that all of the shares of the Common Stock offered hereby have been
sold or which deregisters all such shares then remaining unsold, shall be deemed
to be incorporated by reference herein and to be part hereof from the date of
filing of such documents.

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

          Not applicable.

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

          None.

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

          The California General Corporations Law permits the indemnification of
officers, directors, employees and agents of the Company. The Company's Bylaws
and Indemnification Agreements between the Company and its officers and
directors require the Company to indemnify such persons to the fullest extent
permitted by law. Each person will generally be indemnified in any proceeding if
he acted in good faith and in a manner which he reasonably believed to be in the
best interests of the Company and, in the case of a criminal proceeding, had no
reasonable cause to believe his conduct was unlawful. Indemnification would
cover expenses, including attorneys' fees, judgments, fines and amounts paid in
settlement. In addition, the Company's Articles of Incorporation provide that
directors shall not be personally liable to the Company or its shareholders for
monetary damages for breach





                                       1
   4



of their fiduciary duty, provided, however, that a director's liability will not
be limited in the case of (i) acts or omissions that show a reckless disregard
for the director's duty to the corporation or its shareholders in circumstances
in which the director was aware, or should have been aware, in the ordinary
course of performing his duties, of a risk of serious injury to the corporation
or its shareholders, (ii) for acts or omissions that constitute an unexcused
pattern of inattention that amounts to an abdication of the director's duty to
the corporation or its shareholders, (iii) any transaction from which the
director derived an improper personal benefit, (iv) acts or omissions that the
director believed to be contrary to the best interests of the corporation or
that involved an absence of good faith or that involved intentional misconduct
or a knowing and culpable violation of law, (v) transactions in which the
director has a material financial interest or involve interrelated directors,
and (vi) distributions, loans or guaranties in violation of California law.

          Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers or persons
controlling the Company pursuant to the foregoing provisions, the Company has
been informed that in the opinion of the Commission such indemnification is
against public policy as expressed in the Securities Act of 1933 and is
therefore unenforceable.

Item 7.   Exemption from Registration Claimed

Item 9.   Undertakings
          ------------

          The Company hereby undertakes: (1) to file, during any period in which
offers or sales of the Common Stock 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, as amended (the "Securities
Act"); (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 that
if the information required in clauses (i) and (ii) above to be included in a
post-effective amendment hereto is contained in one or more periodic reports
filed by the registrant pursuant to Section 13 or Section 15(d) of the
Securities Exchange Act of 1934, as amended (the "Exchange Act") no
post-effective amendment hereto shall be required; (2) that, for the purpose of
determining any liability under the Securities Act, 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; and (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.

          Additionally, the undersigned registrant hereby undertakes that, for
purposes of determining any liability under the Securities Act, each filing of
the Company's annual report pursuant to Section 13(a) or 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.

          Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of the Company 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
Securities 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 in the successful defense of any action, suit or proceeding) is asserted
by such director, officer or controlling person in connection with the
securities


                                       3
   6

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 Securities Act and will be governed by
the final adjudication of such issue.
