(1) Pursuant to Rule 429 of the Securities Act of 1933, as amended (the
    "Securities Act"), the prospectus delivered to participants under the
    registrant's 1995 Stock Option Plan (the "Plan") also relates to 450,000
    shares (giving effect to a 3-for-2 stock split effective January 2, 
    1997) initially registered under registration statement on Form S-8 No.
    33-80903.

(2) The Proposed Maximum Offering Price Per Share was estimated in part
    pursuant to Rule 457(h) under the Securities Act of 1933, as amended (the
    "Securities Act"), and, in part, pursuant to Rule 457(c) under the
    Securities Act.  With respect to (i) 391,750 shares which are subject to
    outstanding options to purchase Common Stock under the Plan as of March 24,
    1997 and (ii) 242,640 shares which are subject to outstanding options to
    purchase Common Stock under an Executive Stock Option Agreement, as amended
    (the "Agreement"), the Proposed Maximum Offering Price Per Share was
    estimated pursuant to Rule 457(h), under which Rule the per share price of
    options to purchase stock under an employee stock option plan may be
    estimated by reference to the exercise price of such options.  The weighted
    average exercise price of the 391,750 shares subject to outstanding options
    under the Plan is $7.49 and the exercise price of the 242,640 shares
    subject to outstanding options under the Agreement is $6.75.  With respect
    to 808,250 shares of Common Stock available for future grant under the Plan
    as of March 24, 1997, the Proposed Maximum Offering Price Per Share was
    estimated pursuant to Rule 457(c) under which Rule the per share price was
    determined by reference to the average of the high and low price reported
    in the Nasdaq National Market on April 9, 1997, which average was
    $5.4375.  The number 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).

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Section 145 of the Delaware General Corporation Law allows for the 
indemnification of officers, directors, employees and other corporate agents 
in terms sufficiently broad to indemnify such persons under certain 
circumstances for liabilities (including reimbursements for expenses 
incurred) arising under the Act.  Article VII of the Registrant's Certificate 
of Incorporation and Article VI of the Registrant's Bylaws provide for 
indemnification of the Registrant's directors, officer, employees and other 
agents to the extent and under the circumstances permitted by the Delaware 
General Corporation Law.

     The Registrant has entered into an indemnification agreement with each 
of its directors and officers and maintains insurance for the benefit of its 
directors and officers insuring such persons against certain liabilities, 
including liabilities under the securities laws.

ITEM 7.  EXEMPTION FROM REGISTRATION CLAIMED.

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 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.

          (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)  Insofar as indemnification for liabilities arising under the 
Securities Act 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 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.

    outstanding options to purchase Common Stock under the Plan as of March 24,
    1997 and (ii) 242,640 shares which are subject to outstanding options to
    purchase Common Stock under an Executive Stock Option Agreement, as amended
    (the "Agreement"), the Proposed Maximum Offering Price Per Share was
    estimated pursuant to Rule 457(h), under which Rule the per share price of
    options to purchase stock under an employee stock option plan may be
    estimated by reference to the exercise price of such options.  The weighted
    average exercise price of the 391,750 shares subject to outstanding options
    under the Plan is $7.49 and the exercise price of the 242,640 shares
    subject to outstanding options under the Agreement is $6.75.  With respect
    to 808,250 shares of Common Stock available for future grant under the Plan
    as of March 24, 1997, the Proposed Maximum Offering Price Per Share was
    estimated pursuant to Rule 457(c) under which Rule the per share price was
    determined by reference to the average of the high and low price reported
    in the Nasdaq National Market on April 9, 1997, which average was
    $5.4375.  The number 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).

     There are hereby incorporated by reference in this Registration Statement
the following documents and information heretofore filed with the Securities and
Exchange Commission:

     (a)  The Registrant's Annual Report on Form 10-K for the fiscal year ended
May 31, 1996, filed pursuant to Section 13 of the Securities Exchange Act of
1934 (the "Exchange Act").

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

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.

     Counsel for the Company, Wilson, Sonsini, Goodrich & Rosati, P.C., 650 Page
Mill Road, Palo Alto, California 94304, has rendered and opinion to the effect
that the Common Stock offered hereby will, when issued in accordance with the
Company's 1995 Stock Option Plan and the Executive Stock Option Agreement, as
amended, be legally and validly issued, fully paid and nonassessable.  Jeffrey
D. Saper, a member of Wilson Sonsini Goodrich & Rosati, P.C., is a director of
the Company.  As of March 25, 1997, Mr. Saper, together with investment
partnerships of Wilson Sonsini Goodrich & Rosati, P.C., owns 111,750 shares of
the Common Stock of the Company and holds options to purchase an additional
22,500 shares of the Common Stock of the Company.

                                     II-1
ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Section 145 of the Delaware General Corporation Law allows for the 
indemnification of officers, directors, employees and other corporate agents 
in terms sufficiently broad to indemnify such persons under certain 
circumstances for liabilities (including reimbursements for expenses 
incurred) arising under the Act.  Article VII of the Registrant's Certificate 
of Incorporation and Article VI of the Registrant's Bylaws provide for 
indemnification of the Registrant's directors, officer, employees and other 
agents to the extent and under the circumstances permitted by the Delaware 
General Corporation Law.

     The Registrant has entered into an indemnification agreement with each 
of its directors and officers and maintains insurance for the benefit of its 
directors and officers insuring such persons against certain liabilities, 
including liabilities under the securities laws.

ITEM 7.  EXEMPTION FROM REGISTRATION CLAIMED.

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 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.

          (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)  Insofar as indemnification for liabilities arising under the 
Securities Act 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 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.
