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 (the "Commission"):

          (a) The Company's Annual Report on Form 10-K for the fiscal year ended
December 31, 1996 filed pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934, as amended (the "Exchange Act").

          (b) The Company's Quarterly Report on Form 10-Q for the quarter ended 
March 31, 1997 filed pursuant to Section 13(a) or 15(d) of the Exchange Act.

          (c) The Company's Quarterly Report on Form 10-Q for the quarter ended 
June 30, 1997 filed pursuant to Section 13(a) or 15(d) of the Exchange Act.

          (d) The description of the Company's Common Stock contained in the
Company's Registration Statement on Form 8-A filed pursuant to Section 12(g) of
the Exchange Act, which became effective on February  8, 1993 and was
subsequently amended on November 19, 1996 and on July 29, 1997.

          All documents filed by the Registrant pursuant to Sections 13(a), 
13(c), 14 and 15(d) of the Exchange Act subsequent to the filing 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 the Registration Statement and to be part hereof from the date of
filing of such documents.

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

          The description of the Company's Common Stock to be offered hereby is
incorporated by reference to the Company's Registration Statement on Form 8-A
filed pursuant to Section 12(g) of the Exchange Act, which became effective on
February 8, 1993 and was subsequently amended on November 19, 1996 and on July
29, 1997.

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

          Not applicable.

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

          Section 145 of the Delaware General Corporation Law authorizes a 
court to award or a corporation's Board of Directors to grant indemnification to
directors and officers in terms sufficiently broad to permit such
indemnification under certain circumstances for liabilities (including
reimbursement for expenses incurred) arising under the Securities Act of 1933
(the "Securities Act"), as amended. The Company has included in its Certificate
of Incorporation a provision that to the fullest extent permitted by Delaware
law, the Company's directors will not be liable for monetary damages for breach
of the directors' fiduciary duty of care to the Company and its stockholders. 

                                     II-1

 
In addition, the Company's Bylaws provide that the Company is required to
indemnify its officers and directors to the fullest extent permitted by Delaware
law, including those circumstances in which indemnification would otherwise be
discretionary, and that the Company is required to advance expenses to its
officers and directors as incurred. Further, the Company intends to enter into
indemnification agreements with its officers and directors, providing such
individuals indemnification to the maximum extent permitted by the Delaware
General Corporation Law.

          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 Delaware General Corporation Law, the foregoing
Bylaw provision or any Indemnification Agreement, the Company has been informed
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.

Item 7.   Exemption from Registration Claimed.
          ----------------------------------- 
 
          Not applicable.
 
Item 8.   Exhibits.

          Number                           Description

            4.2        1992 Employee Stock Purchase Plan, as amended.
            4.3        1995 Director Option Plan, as amended.
            5.1        Opinion of Wilson, Sonsini, Goodrich & Rosati,
                       P.C. as to legality of securities being registered.
           23.1        Consent of Wilson, Sonsini, Goodrich & Rosati,
                       P.C. (contained in Exhibit 5.1).
           23.2        Consent of Independent Auditors (see page II-6).
           24.1        Power of Attorney (see page II-4).

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 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 that remain unsold at the
termination of the offering.

          (b) 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
                                     II-2

 
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 an 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 Delaware General Corporation Law, the
Certificate of Incorporation of the Registrant, the Bylaws of the Registrant,
Indemnification Agreements entered into between the Registrant and its officers
and directors, 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.

                                     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 Mountain View, State of California,
on this 12th day of August, 1997.
