   This Post-Effective Amendment No. 1 is being filed solely to file Exhibit
99.1, the Form of Proxy for the registrant, as amended. No changes have been
made to Part I or Part II of this registration statement, other than Item 21
(Exhibits and Financial Statement Schedules) of Part II. In particular, there
have been no changes to Item 20 (Indemnification of Officers and Directors) or
Item 22 (Undertakings) of Part II. Accordingly, Part I is not being filed
herewith. Part II is being filed in its entirety, as amended.


                                    PART II

                    INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20.  Indemnification of Officers and Directors

   Section 145 of the General Corporation Law of the State of Delaware
authorizes a court to award or a corporation's board of directors to grant
indemnification to directors and officers in terms that are sufficiently broad
to permit indemnification under certain circumstances for liabilities
(including reimbursement for expenses incurred) arising under the Securities
Act of 1933. HP's certificate of incorporation contains a provision eliminating
the personal liability of its directors to the company or its shareowners for
breach of fiduciary duty as a director to the fullest extent permitted by
applicable law. HP's bylaws provide for the mandatory indemnification of our
directors and officers to the maximum extent permitted by Delaware law. HP's
bylaws also provide (i) that we may expand the scope of the indemnification by
individual contracts with our directors and officers, and (ii) that we shall
not be required to indemnify any director or officer unless the indemnification
is required by law, if the proceeding in which indemnification is sought was
brought by a director or officer, it was authorized in advance by our board of
directors, the indemnification is provided by us, in our sole discretion
pursuant to powers vested in us under the Delaware law, or the indemnification
is required by individual contract. In addition, our bylaws give us the power
to indemnify our employees and agents to the maximum extent permitted by
Delaware law.

Item 22.  Undertakings

   The undersigned registrant hereby undertakes:

      (1) 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 into this 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;

      (2) insofar as indemnification for liabilities under the Securities Act
   of 1933 may be permitted to directors, officers and controlling persons of
   the registrant pursuant to the provisions described in Item 20 above, 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. If
   a claim of 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 a 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;

      (3) to respond to requests for information that is incorporated by
   reference into the prospectus pursuant to Item 4, 10(b), 11 or 13 of this
   Form S-4, within one business day of receipt of any such request, and to
   send the incorporated documents by first class mail or other equally prompt
   means. This includes information contained in documents filed after the
   effective date of the registration statement through the date of responding
   to such request; and

      (4) to supply by means of a post-effective amendment all information
   concerning a transaction, and the company being acquired involved therein,
   that was not the subject of and included in the registration statement when
   it became effective.

                                     II-2



                                  SIGNATURES


   Pursuant to the requirements of the Securities Act, the registrant has duly
caused this Post-Effective Amendment No. 1 to the registrant's registration
statement on Form S-4 to be signed on its behalf by the undersigned, thereunto
duly authorized, in the city of Palo Alto, State of California, on February 5,
