2)  The Proposed Maximum Offering Price Per Share was estimated in part
    pursuant to Rule 457(h) under the Securities Act.  With respect to 100,000
    shares of Common Stock available for future grant under the Plan,
    920,000 shares of Common Stock available for future grant under the
    Long-Term Plan and 500,000 shares of Common Stock available for future
    grant under the Supplemental Incentive Plan, the estimated Proposed
    Maximum Offering Price Per Share was estimated pursuant to Rule 457(c)
    whereby the per share price was determined by reference to the average
    between the high and low price reported in the NASDAQ National Market
    on August 19, 1999, which average was $6.1565.  The number referenced
    referenced above in the table entitled "Proposed Maximum Offering
    Price Per Share" represents a weighted average of the foregoing
    estimates calculated in accordance with Rules 457(h) and 457(c).

     (b) The Registrant's Quarterly Report on Form 10-Q for the fiscal

     (e) The Registrant's Proxy Statement in Schedule 14A for the 1999

     In addition, all documents subsequently filed by the Registrant pursuant
to Sections 13(a), 13(c), 14 and 15(d) of the Securities Exchange Act of
1934, prior to the filing of a post-effective amendment which indicates
that all securities offered have been sold or which deregisters all
securities then remaining unsold, shall be deemed to be incorporated by
reference in this registration statement and to be part hereof from the
date of filing such documents.

Item 4.     Description of Securities.

     Not applicable.

Item 5.     Interests of Named Experts and Counsel.

     Not applicable.

Item 6.     Indemnification of Directors and Officers.

     The By-Laws of the Company provide for the indemnification of directors
and officers to the fullest extent permitted by the General Corporation
Law of the State of California.

     Section 317 of the General Corporation Law of the State of California
authorizes indemnification when a person is made a party to any
proceeding by reason of the fact that such person is or was a director,
officer, employee or agent of the corporation or was so serving at the
request of the corporation in such capacity for another corporation, and
if such person acted in good faith and in a manner reasonably believed
to be in, or not opposed to, the best interest of the corporation.  With
respect to any criminal proceeding, such person must have had no
reasonable cause to believe the conduct was unlawful.  If it is
determined that the conduct of such person meets these standards, such
person may be indemnified for expenses incurred and amounts paid in such
proceedings if actually and reasonably incurred in connection therewith.

     If such a proceeding is brought by or on behalf of the corporation
(i.e., a derivative suit), such person may be indemnified against
expenses actually and reasonably believed to be in, or not opposed to,
the best interests of the corporation.  There can be no indemnification
with respect to any matter as to which such person is adjudged to be
liable to the corporation for negligence or misconduct in the
performance of his or her duty; however, a court may, even in such case,
allow indemnification of such expenses as the court deems proper.  Where
such person is successful in any such proceeding, he or she is entitled
to be indemnified against expenses actually and reasonably incurred by
him or her.  In all other cases, indemnification is made by the
corporation upon determination by it that indemnification of such person
is proper because such person has met the applicable standard of
conduct.

     The Company has also entered into indemnification agreements with its
directors and certain officers which contractually obligate the Company
to indemnify such persons to the fullest extent permitted under
California law.

     The California General Corporation Law permits a California corporation
to include in its Articles of Incorporation a provision eliminating or
limiting the liability of directors for monetary damages arising from
breaches of their fiduciary duty.  The only limitations imposed under
the statute are that the provisions may not eliminate or limit a
director's liability (i) for acts or omissions that involve intentional
misconduct or a knowing and culpable violation of law, (ii) for acts or
omissions that a director believes to be contrary to the best interests
of the corporation or its shareholders or that involve the absence of
good faith on the part of the director, (iii) for any transaction from
which a director derived an improper personal benefit, (iv) for 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 a director's duties, of a risk of serious injury to the
corporation or its shareholders, (v) 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, or (vi) for the payment of unlawful dividends, stock
purchases or redemptions.  The Company's Articles of Incorporation
contain a provision eliminating the liability of the Company's directors
for breaches of their fiduciary duty, subject to the limitations imposed
by statute as described above.  The provisions do not limit or otherwise
affect the personal liability of a director for violation of Federal
Securities Law.

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 this 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 this Registration Statement;

          (iii)  To include any material information with respect
to the plan of distribution not previously disclosed in this
Registration Statement or any material change to such information in
this Registration Statement; provided however, that paragraphs (a)(1)(i)
and (a)(1)(ii) do not apply if the information required to be included
in a post-effective amendment by those paragraphs is contained in
periodic reports filed by Registrant pursuant to Section 13 or Section
15(d) of the Securities Exchange Act of 1934 that are incorporated by
reference in this Registration Statement.

       (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.

       (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, 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.

     (c)  (1)  The undersigned Registrant hereby undertakes to
deliver or cause to be delivered with the Prospectus to each person to
whom the Prospectus is sent or given a copy of Registrant's annual
report to shareholders for its last fiscal year, unless such employee
otherwise has received a copy of such report, in which case Registrant
shall state in the Prospectus that it will promptly furnish, without
charge, a copy of such report on written request of the employee.  If
the last fiscal year of Registrant has ended within 120 days prior to
the use of the Prospectus, the annual report of Registrant for the
preceding fiscal year may be so delivered, but within such 120-day
period the annual report for the last fiscal year will be furnished to
each such employee.

          (2)  The undersigned Registrant hereby undertakes to
transmit or cause to be transmitted to all employees participating in
the Plan who do not otherwise receive such material as shareholders of
registrant, at the time and in the manner such material is sent to its
shareholders, copies of all reports, proxy statements and other
communications distributed to its shareholders generally.

     (d)  Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and
controlling persons of Registrant pursuant to the foregoing provisions,
or otherwise, 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 Registrant of expenses incurred or paid by a
director, officer or controlling person of 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, 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.


                              SIGNATURES

        Pursuant to the requirements of the Securities Act of 1933,
the Registrant certifies that it has reasonable grounds to believe
that it meets all of the requirements for filing on Form S-8 and

behalf by the undersigned, thereunto duly authorized, in Milpitas,
