         (a) Annual Report on Form 10-K for the fiscal year ended October 31,
1999 filed with the Securities and Exchange Commission (the "Commission") on
January 27, 2000;

         (b) All other reports filed pursuant to Section 13(a) or 15(d) of the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), since the end
of the fiscal year covered by the Company document referred to in (a) above; and

         All documents subsequently filed by the Company pursuant to Sections
13(a), 13(c), 14 and 15(d) of the Exchange Act, prior to the filing of a
post-effective amendment to this registration statement which indicates that all
securities offered hereby have been sold or which deregisters all securities

Item 4. Description of Securities.

        Not applicable.

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 ("Delaware Law")
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. The
Company's bylaws provide for the mandatory indemnification of the directors and
officers to the maximum extent permitted by Delaware law. The bylaws also
provide (i) that the Company may modify the scope of indemnification by
individual contracts with the directors and officers, and (ii) that the Company
shall not be required to indemnify any director or officer unless the
indemnification is required by law, the proceeding in which indemnification is
sought was authorized in advance by our board of directors, the indemnification
is provided by the Company, in the sole discretion pursuant to powers vested in
the Company under the Delaware Law or the indemnification is required by
individual contract. In addition the bylaws provide that the Company has the
power to indemnify its employees and agents to the maximum extent permitted by
Delaware law.

Item 7.  Exemption from Registration Claimed.

         Not applicable.

Item 8.  Exhibits.

         See Exhibit Index on page 6.

Item 9.  Undertakings.

         (a) Rule 415 Offering.

         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; (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; and (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 clauses
(1)(i) and (1)(ii) shall not apply if the information required to be included in
a post-effective amendment by those paragraphs is contained in periodic reports
filed by the registrant pursuant to Section 13 or Section 15(d) of the Exchange
Act that are incorporated by reference into 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) Filings Incorporating Subsequent Exchange Act Documents by
Reference.

         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 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) Regulation S-K Item 512(h) Undertaking for Registration
Statement on Form S-8.

         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 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.

information in this registration statement; provided, however, that clauses
(1)(i) and (1)(ii) shall not apply if the information required to be included in
a post-effective amendment by those paragraphs is contained in periodic reports
filed by the registrant pursuant to Section 13 or Section 15(d) of the Exchange
Act that are incorporated by reference into 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) Filings Incorporating Subsequent Exchange Act Documents by
Reference.

         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 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) Regulation S-K Item 512(h) Undertaking for Registration
Statement on Form S-8.

         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 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.
