                                     PART II

               INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

Item 3.  Incorporation of Documents by Reference.

     The Securities and Exchange  Commission  rules and regulations  allow us to
"incorporate by reference" the information  that we file with the Securities and
Exchange  Commission.  This  means  that we can  disclose  additional  important
information to you by referring to those documents. The information incorporated
by reference is an important part of this  Prospectus,  and information  that we
file  in  the  future  with  the   Securities  and  Exchange   Commission   will
automatically update and supersede this information. We have filed the following
documents  with the  Securities  and  Exchange  Commission  and the  information
contained in those documents is incorporated by reference into this registration
statement:

(1)  Registrant's  Annual Report on Form 10-K for the fiscal year ended June 30,
     2002;

(2)  Registrant's  Quarterly  Reports  on  Form  10-Q  for  the  quarters  ended
     September 30, 2002 and December 31, 2002;

(3)  Registrant's  Proxy  Statement  for the Annual  Meeting held on January 30,
     2003;

(4)  Registrant's  Current Reports on Form 8-K filed on March 25, 2003 and April
     2, 2003; and

(5)  The Description  of Securities in Item 1 of the  Registration  Statement on
     Form  8A  for  registration  of the  Registrant's  common stock pursuant to
     Section 12(g) of the Exchange Act.

Item 4.  Description of Securities.

     The  Registrant's  common  stock  to be  offered  under  this  registration
statement is registered under Section 12 of the Exchange Act.

Item 5.  Interests of Named Experts and Counsel.

     The  legality of the shares of common stock  offered  hereby will be passed
upon for the Company by Bartel Eng & Schroder, Sacramento, California. As of the
date of this  registration  statement,  certain members of Bartel Eng & Schroder
own an aggregate of 17,822 shares of common stock, including 4,722 warrants.

Item 6.  Indemnification of Directors and Officers.

     The Company is incorporated  in Delaware.  Under Section 145 of the General
Corporation Law of the State of Delaware,  a Delaware  corporation has the power
to  indemnify  its  directors,  officers,  employees  and agents  from  expenses



(including  attorney's fees),  judgments,  fines, and amounts paid in settlement
actually and reasonably  incurred in connection with a threatened,  pending,  or
completed action, suit or proceeding,  whether civil, criminal,  administrative,
or  investigative,  in which such  person is involved by reason of the fact such
person were or are  directors,  officers,  employees  or agents of the  Company,
provided  that such person  acted in good faith and in a manner that such person
reasonably  believed to be in the best interests of the corporation  and, in the
case of a criminal  proceeding,  such person had no reasonable  cause to believe
his or her  conduct was  unlawful.  Such  person may not be  indemnified  if the
person has been adjudged  liable to the  corporation in the  performance of such
person's duties to the corporation, unless the Court of Chancery or the court in
which  such  action  or  suit  was  brought  determines  that,  in  view  of the
circumstances  of the case,  such  person is fairly and  reasonably  entitled to
indemnity.  To the extent that such person has been  successful on the merits or
otherwise in defense of any proceeding,  the General  Corporate Law of the State
of Delaware  provides  that such person shall be  indemnified  against  expenses
(including attorney's fees) reasonably and actually incurred. The Certificate of
Incorporation  and the By-laws of the Company  provide  for  indemnification  of
directors  and  officers  to  the  fullest  extent   permitted  by  the  General
Corporation Law of the State of Delaware.

     The  General  Corporation  Law of the  State of  Delaware  provides  that a
certificate of  incorporation  may contain a provision  eliminating the personal
liability  of a director to the  corporation  or its  stockholders  for monetary
damages for breach of fiduciary duty as a director  provided that such provision
shall not  eliminate or limit the  liability of a director (i) for any breach of
the director's duty of loyalty to the corporation or its stockholders,  (ii) for
acts or omissions not in good faith or which involve intentional misconduct or a
knowing  violation  of law,  (iii) for  unlawful  payment of  dividends or stock
redemption,  or (iv) for any  transaction  from  which the  director  derived an
improper personal benefit. The Company's  Certificate of Incorporation  contains
such a provision.

Item 7.  Exemption from Registration Claimed.

     Not applicable.

Item 8.  Exhibits.

Exhibit Number       Description of Exhibit
--------------       ----------------------

      4.1            Amended 1998 Employee Equity Incentive Plan(1)

      5.1            Opinion of Bartel Eng & Schroder dated May 8, 2003.

     23.1            Consent of Bartel Eng & Schroder (contained in Exhibit 5.1)

     23.2            Consent of Ernst & Young LLP, Independent Auditors


(1) Incorporated by reference from the Company's Proxy Statement for the meeting
    held on February 2, 1997 (File No.: 000-16375).


Item 9.  Undertakings.

(f) 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.  Notwithstanding the foregoing, any increase or decrease in volume of
securities  offered (if the total dollar value of  securities  offered would not
exceed that which was  registered) and any deviation from the low or high end of
the estimated  maximum offering range may be reflected in the form of prospectus
filed with the  Commission  pursuant  to Rule 424(b) if, in the  aggregate,  the
changes in volume and price  represent  no more than a 20% change in the maximum
aggregate  offering price set forth in the  "Calculation  of  Registration  Fee"
table in the effective 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,  Form S-8 or Form F-3,  and the
information  required  to be  included in a  post-effective  amendment  by those
paragraphs  is  contained  in periodic  reports  filed with or  furnished to the
Commission  by the  registrant  pursuant  to Section 13 or Section  15(d) of the
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  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  (and,  where  applicable,  each  filing of an
employee  benefit  plan's  annual  report  pursuant  to  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.

                                     * * * *

(h) 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 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 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 of 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, the Registrant

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 Rancho Cordova, State of California.
