REGISTRATION STATEMENT ON FORM S-8 PART II INFORMATION REQUIRED IN THE REGISTRATION STATEMENT ITEM 3. INCORPORATION OF DOCUMENTS BY REFERENCE. --------------------------------------- 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 January 31, 1997, filed pursuant to Section 13 of the Securities Exchange Act of 1934, as amended (the "1934 Act"); (b) The Registrant's Quarterly Report on Form 10-Q for the quarter ended October 31, 1997, filed pursuant to Section 13 of the 1934 Act; (c) The description of the Registrant's Common Stock contained in the Registrant's Registration Statement on Form 8-A dated March 18, 1986 pursuant to Section 12(g) of the 1934 Act. In addition, all documents filed by the Registrant pursuant to Sections 13(a), 13(c), 14 and 15(d) of the 1934 Act on or after the date of this Registration Statement and 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 of such documents. ITEM 4. DESCRIPTION OF SECURITIES. ------------------------- Not applicable. ITEM 5. INTERESTS OF NAMED EXPERTS AND COUNSEL. -------------------------------------- Mark Bertelsen, a director of the Registrant, is a member of Wilson Sonsini Goodrich & Rosati, which has given an opinion upon the validity of the securities being registered by this Registration Statement. ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS. ------------------------------------------ As permitted by Section 145 of the Delaware General Corporation Law, the Registrant's Certificate of Incorporation, as amended, includes a provision that eliminates the personal liability of its directors for monetary damages for breach or alleged breach of their duty of care. In addition, as permitted by Section 145 of the Delaware General Corporation Law, the Bylaws of the Registrant provide that: (i) the Registrant is required to indemnify its directors and officers and persons serving in such capacities in other business enterprises (including, for example, subsidiaries of the Registrant) at the Registrant's request, to the fullest extent permitted by Delaware law; (ii) the Registrant may, in its discretion, indemnify employees and agents in those circumstances where indemnification is not required by law; (iii) the Registrant is required to advance expenses, as incurred, to its directors and officers in connection with defending a proceeding, provided that payment of expenses incurred by a director or officer of the corporation in advance of the final disposition of such proceeding shall be made only on receipt of an undertaking by the officer or director to repay all amounts advanced if it should ultimately be determined that the officer or director is not entitled to be indemnified; (iv) the rights conferred in the Bylaws are not exclusive, and the Registrant is authorized to enter into II-1 indemnification agreements with its directors, officers and employees; and (v) the Registrant may not retroactively amend the Bylaw provisions in a way that is adverse to such directors, officers and employees. The Registrant's policy is to enter into indemnification agreements with each of its directors and officers that provide the maximum indemnity allowed to directors and officers by Section 145 of the Delaware General Corporation Law and the Bylaws, as well as certain additional procedural protections. In addition, the indemnification agreements provide that directors and officers will be indemnified to the fullest possible extent permitted by law against all expenses (including attorney's fees) and settlement amounts paid or incurred by them in an action or proceeding, including any action by or in the right of the Registrant, arising out of such person's services as a director or officer of the Registrant, any subsidiary of the Registrant or any other company or enterprise to which such person provides services at the request of the Registrant. The Registrant will not be obligated pursuant to the indemnification agreements to indemnify or advance expenses to an indemnified party with respect to proceedings or claims initiated by the indemnified party and not by way of defense, except with respect to proceedings specifically authorized by the Board of Directors or brought to enforce a right to indemnification under the indemnification agreement, the Registrant's Bylaws or any statute or law. Under the agreements, the Registrant is not obligated to indemnify the indemnified party (i) for any expenses incurred by the indemnified party with respect to any proceeding instituted by the indemnified party to enforce or interpret the agreement, if a court of competent jurisdiction determines that each of the material assertions made by the indemnified party in such proceeding was not made in good faith or was frivolous; (ii) for any amounts paid in settlement of a proceeding unless the Registrant consents to such settlement; (iii) on account of any suit in which judgment is rendered against the indemnified party for an accounting of profits made from the purchase or sale by the indemnified party of securities of the Registrant pursuant to the provisions of Section 16(b) of the Securities Exchange Act of 1934 and related laws; or (iv) if a final decision by a court having jurisdiction in the matter shall determine that such indemnification is not lawful. The indemnification provisions in the Bylaws and the indemnification agreements entered into between the Registrant and its directors and officers may be sufficiently broad to permit indemnification of the Registrant's directors and officers for liabilities arising under the Securities Act.

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 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. C. Insofar as indemnification for liabilities arising under the Securities Act of 1933 (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 hereunder, 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. II-3 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 has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of San Rafael, State of California, on this 28th day of January, 1998.

          (xi)   to determine the terms and restrictions applicable to Options;

          (xii)  to allow Optionees to satisfy withholding tax obligations by
electing to have the Company withhold from the Shares to be issued upon exercise
of an Option that number of Shares having a Fair Market Value equal to the
amount required to be withheld; and

          (xiii) to make all other determinations deemed necessary or advisable
for administering the Plan.

      (c) Effect of Administrator's Decision.  The Administrator's decisions,
          ----------------------------------                                 
determinations and interpretations shall be final and binding on all Optionees
and any other holders of Options.

  5.  Eligibility.  Stock Options may be granted to Employees and Consultants.
      -----------                                                             

  6.  Limitations.  Neither the Plan nor any Option shall confer upon an
      -----------                                                       
Optionee any right with respect to continuing the Optionee's employment or
consulting relationship with the Company, nor shall they interfere in any way
with the Optionee's right or the Company's right to terminate such employment or
consulting relationship at any time, with or without cause.

  7.  Term of Plan.  The Plan shall become effective upon its adoption by the
      ------------                                                           
Board.  It shall continue in effect until terminated under Section 14 of the
Plan.

  8.  Term of Option.  The term of each Option shall be stated in the Notice of
      --------------                                                           
Grant.

  9.  Option Exercise Price and Consideration.
      --------------------------------------- 

      (a) Exercise Price.  The per share exercise price for the Shares to be
          --------------                                                    
issued pursuant to exercise of an Option shall be determined by the
Administrator.

      (b) Waiting Period and Exercise Dates.  At the time an Option is granted,
          ---------------------------------                                    
the Administrator shall fix the period within which the Option may be exercised
and shall determine any conditions which must be satisfied before the Option may
be exercised.  In so doing, the Administrator may specify that an Option may not
be exercised until either the completion of a service period or the achievement
of performance criteria with respect to the Company or the Optionee.

      (c) Form of Consideration.  The Administrator shall determine the
          ---------------------                                        
acceptable form of consideration for exercising an Option, including the method
of payment.   Such consideration may consist entirely of:

          (i)  cash;

          (ii) check;

                                       4

 
          (iii) promissory note;

          (iv)  other Shares which (A) in the case of Shares acquired upon
exercise of an option, have been owned by the Optionee for more than six months
on the date of surrender, and (B) have a Fair Market Value on the date of
surrender equal to the aggregate exercise price of the Shares as to which said
Option shall be exercised;

          (v)   delivery of a properly executed exercise notice together with
such other documentation as the Administrator and the broker, if applicable,
shall require to effect an exercise of the Option and delivery to the Company of
the sale or loan proceeds required to pay the exercise price;

          (vi)   a reduction in the amount of any Company liability to the
Optionee, including any liability attributable to the Optionee's participation
in any Company-sponsored deferred compensation program or arrangement;

          (vii)  any combination of the foregoing methods of payment; or

          (viii) such other consideration and method of payment for the issuance
of Shares to the extent permitted by Applicable Laws.

  10. Exercise of Option.
      ------------------ 

      (a) Procedure for Exercise; Rights as a Shareholder. Any Option granted
          -----------------------------------------------                    
hereunder shall be exercisable according to the terms of the Plan and at such
times and under such conditions as determined by the Administrator and set forth
in the Option Agreement.

          An Option may not be exercised for a fraction of a Share.

          An Option shall be deemed exercised when the Company receives: (i)
written or electronic notice of exercise (in accordance with the Option
Agreement) from the person entitled to exercise the Option, and (ii) full
payment for the Shares with respect to which the Option is exercised.  Full
payment may consist of any consideration and method of payment authorized by the
Administrator and permitted by the Option Agreement and the Plan.  Shares issued
upon exercise of an Option shall be issued in the name of the Optionee or, if
requested by the Optionee, in the name of the Optionee and his or her spouse.
Until the Shares are issued (as evidenced by the appropriate entry on the books
of the Company or of a duly authorized transfer agent of the Company), no right
to vote or receive dividends or any other rights as a shareholder shall exist
with respect to the Optioned Stock, notwithstanding the exercise of the Option.
The Company shall issue (or cause to be issued) such Shares promptly after the
Option is exercised.  No adjustment will be made for a dividend or other right
for which the record date is prior to the date the Shares are issued, except as
provided in Section 12 of the Plan.

          Exercising an Option in any manner shall decrease the number of Shares
thereafter available, both for purposes of the Plan and for sale under the
Option, by the number of Shares as to which the 

                                       5

 
Option is exercised.

      (b) Termination of Employment or Consulting Relationship.  In the event an
          ----------------------------------------------------                  
Optionee ceases to be an Employee or Consultant, other than upon the Optionee's
death or Disability, the Optionee may exercise his or her Option within such
period of time as is specified in the Notice of Grant to the extent that he or
she is entitled to exercise it on the date of termination (but in no event later
than the expiration of the term of such Option as set forth in the Notice of
Grant).  In the absence of a specified time in the Notice of Grant, the Option
shall remain exercisable for three (3) months following the Optionee's
termination.  If, on the date of termination, the Optionee is not entitled to
exercise his or her entire Option, the Shares covered by the unexercisable
portion of the Option shall revert to the Plan.  If, after termination, the
Optionee does not exercise his or her Option within the time specified by the
Administrator, the Option shall terminate, and the Shares covered by such Option
shall revert to the Plan.

      Notwithstanding the above, in the event of an Optionee's change in status
from Consultant to Employee or Employee to Consultant, the Optionee's Continuous
Status as an Employee or Consultant shall not automatically terminate solely as
a result of such change in status.

      (c) Disability of Optionee.  In the event an Optionee ceases to be an
          ----------------------                                           
Employee or Consultant as a result of the Optionee's Disability, the Optionee
may exercise his or her Option at any time within twelve (12) months (or such
other period of time as is determined by the Administrator) from the date of
termination, but only to the extent that the Optionee is entitled to exercise it
on the date of termination (and in no event later than the expiration of the
term of the Option as set forth in the Notice of Grant).  If, on the date of
termination, the Optionee is not entitled to exercise his or her entire Option,
the Shares covered by the unexercisable portion of the Option shall revert to
the Plan.  If, after termination, the Optionee does not exercise his or her
Option within the time specified herein, the Option shall terminate, and the
Shares covered by such Option shall revert to the Plan.

      (d) Death of Optionee.  In the event of the death of an Optionee, the
          -----------------                                                
Option shall become fully exercisable, including as to Shares for which it would
not otherwise be exercisable and may be exercised at any time within twelve (12)
months (or such other period of time as is determined by the Administrator)
following the date of death (but in no event later than the expiration of the
term of such Option as set forth in the Notice of Grant), by the Optionee's
estate or by a person who acquired the right to exercise the Option by bequest
or inheritance.  If, after death, the Optionee's estate or a person who acquired
the right to exercise the Option by bequest or inheritance does not exercise the
Option within the time specified herein, the Option shall terminate, and the
Shares covered by such Option shall revert to the Plan.

  11. Non-Transferability of Options.  Unless otherwise specified by the
      ------------------------------                                    
Administrator in the Option Agreement, an Option may not be sold, pledged,
assigned, hypothecated, transferred, or disposed of in any manner other than by
will or by the laws of descent or distribution and may be exercised, during the
lifetime of the Optionee, only by the Optionee.

  12. Adjustments Upon Changes in Capitalization, Dissolution, Merger or Asset
      ------------------------------------------------------------------------
      Sale.
      ---- 

                                       6

 
      (a) Changes in Capitalization.  Subject to any required action by the
          -------------------------                                        
shareholders of the Company, the number of Shares covered by each outstanding
Option and the number of Shares which have been authorized for issuance under
the Plan but as to which no Options have yet been granted or which have been
returned to the Plan upon cancellation or expiration of an Option, as well as
the price per Share covered by each such outstanding Option, shall be
proportionately adjusted for any increase or decrease in the number of issued
Shares resulting from a stock split, reverse stock split, stock dividend,
combination or reclassification of the Common Stock, or any other increase or
decrease in the number of issued Shares effected without receipt of
consideration by the Company; provided, however, that conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of consideration."  Such adjustment shall be made by the Board,
whose determination in that respect shall be final, binding and conclusive.
Except as expressly provided herein, no issuance by the Company of Shares of
stock of any class, or securities convertible into Shares of stock of any class,
shall affect, and no adjustment by reason thereof shall be made with respect to,
the number or price of Shares subject to an Option.

      (b) Dissolution or Liquidation.  In the event of the proposed dissolution
          --------------------------                                           
or liquidation of the Company, the Administrator shall notify each Optionee as
soon as practicable prior to the effective date of such proposed transaction.
The Administrator in its discretion may provide for all Options to vest and for
an Optionee to have the right to exercise his or her Option until ten (10) days
prior to such transaction as to all of the Optioned Stock covered thereby,
including Shares as to which the Option would not otherwise be vested and
exercisable.  To the extent it has not been previously exercised, an Option will
terminate immediately prior to the consummation of such proposed action.

      (c) Merger or Asset Sale.  In the event of a merger of the Company with or
          --------------------                                                  
into another corporation, or the sale of substantially all of the assets of the
Company, each outstanding Option shall be assumed or an equivalent option or
right substituted by the successor corporation or a Parent or Subsidiary of the
successor corporation, or in the event that the successor corporation refuses to
assume or substitute for the Option, the Option shall fully vest and the
Optionee shall have the right to exercise the Option as to all of the Optioned
Stock, including Shares as to which it would not otherwise be vested and
exercisable.  If an Option is exercisable in lieu of assumption or substitution
in the event of a merger or sale of assets, the Administrator shall notify the
Optionee in writing or electronically that the Option shall be fully vested  and
exercisable for a period of fifteen (15) days from the date of such notice, and
the Option shall terminate upon the expiration of such period.  For the purposes
of this paragraph, the Option shall be considered assumed if, following the
merger or sale of assets, the option or right confers the right to purchase or
receive, for each Share of Optioned Stock subject to the Option immediately
prior to the merger or sale of assets, the consideration (whether stock, cash,
or other securities or property) received in the merger or sale of assets by
holders of Common Stock for each Share held on the effective date of the
transaction (and if holders were offered a choice of consideration, the type of
consideration chosen by the holders of a majority of the outstanding Shares);
provided, however, that if such consideration received in the merger or sale of
assets was not solely common stock of the successor corporation or its Parent,
the Administrator may, with the consent of the successor corporation, provide
for the consideration to be received upon the exercise of the Option, for each
Share of Optioned Stock subject to the Option, to be solely common stock of the
successor corporation or its Parent equal in fair market value to the per share
consideration received by holders of Common Stock in the merger or sale of
assets.

                                       7

 
  13. Date of Grant.  The date of grant of an Option shall be, for all purposes,
      -------------                                                             
the date on which the Administrator makes the determination granting such
Option, or such other later date as is determined by the Administrator.  Notice
of the determination shall be provided to each Optionee within a reasonable time
after the date of such grant.

  14. Amendment and Termination of the Plan.
      ------------------------------------- 

      (a) Amendment and Termination.  The Board may at any time amend, alter,
          -------------------------                                          
suspend or terminate the Plan.

      (b) Effect of Amendment or Termination.  No amendment, alteration,
          ----------------------------------                            
suspension or termination of the Plan shall impair the rights of any Optionee,
unless mutually agreed otherwise between the Optionee and the Administrator,
which agreement must be in writing and signed by the Optionee and the Company.

  15. Conditions Upon Issuance of Shares.
      ---------------------------------- 

      (a) Legal Compliance.  Shares shall not be issued pursuant to the exercise
          ----------------                                                      
of an Option unless the exercise of such Option and the issuance and delivery of
such Shares shall comply with all Applicable Laws, and the requirements of any
stock exchange or quotation system upon which the Shares may then be listed or
quoted, and shall be further subject to the approval of counsel for the Company
with respect to such compliance.

      (b) Investment Representations.  As a condition to the exercise of an
          --------------------------                                       
Option, the Company may require the person exercising such Option to represent
and warrant at the time of any such exercise that the Shares are being purchased
only for investment and without any present intention to sell or distribute such
Shares if, in the opinion of counsel for the Company, such a representation is
required.

  16. Liability of Company.  The inability of the Company to obtain authority
      --------------------                                                   
from any regulatory body having jurisdiction, which authority is deemed by the
Company's counsel to be necessary to the lawful issuance and sale of any Shares
hereunder, shall relieve the Company of any liability in respect of the failure
to issue or sell such Shares as to which such requisite authority shall not have
been obtained.

  17. Reservation of Shares.  The Company, during the term of this Plan, will at
      ---------------------                                                     
all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.

Ladies and Gentlemen:

     We have examined the Registration Statement on Form S-8 to be filed by you

Securities Act of 1933, as amended, of 850,000 additional shares under the

nonassessable.

Registration Statement and any amendment thereto.
