     (b)  (i)  Quarterly Report on Form 10-Q for the quarterly period ended
March 31, 2001;

          (ii) Current Reports on Form 8-K, dated January 24, 2001, March 28,

22, 1986, Form 8, dated February 3, 1988, Form 8-B/A, dated July 12, 1993, Form

after the date hereof prior to the filing of a post-effective amendment which
indicates that the securities offered hereby have been sold or which deregisters
the securities covered hereby then remaining unsold, shall also be deemed to be
incorporated by reference into this Registration Statement and to be a part
hereof from the date of delivery of such documents. Any statement contained in a
document incorporated or deemed to be incorporated by reference herein shall be
deemed to be modified or superseded for purposes of this Registration Statement
to the extent that a statement contained herein, or in any other subsequently

modifies or supersedes such statement. Any such statement so modified or
superseded shall not be deemed, except as so modified or superseded, to

ITEM 4.  DESCRIPTION OF SECURITIES

     Not applicable.

ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL

     The validity of the Common Stock registered pursuant hereto has been passed
upon by Linda S. Peterson, an Assistant General Counsel of the Registrant. Ms.
Peterson beneficially owns, and has rights to acquire under employee stock
options, an aggregate of less than 1% of the outstanding shares of Common Stock
of Occidental.

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, indemnity to directors
and officers under certain circumstances for liabilities incurred in connection
with their activities in such capacities (including

                                       1
<PAGE>

reimbursement for expenses incurred). Occidental's Restated Certificate of
Incorporation provides for the elimination of personal liability of its
directors to the full extent permitted by the Delaware General Corporation Law
and Occidental has entered into indemnification agreements with each director
and certain officers providing for additional indemnification. Article VIII of
Occidental's By-laws provides that Occidental shall indemnify directors and
officers under certain circumstances for liabilities and expenses incurred by
reason of their activities in such capacities. In addition, Occidental has
insurance policies that provide liability coverage to directors and officers
while acting in such capacities.

         File No. 1-9210).

ITEM 9.  UNDERTAKINGS

     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 of 1933;

               (ii)  To reflect in the prospectus any facts or events arising
after the effective date of the 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 the registration
statement. Notwithstanding the foregoing, any increase or decrease in volume of
securities offered (if the total dollar value of securities offered would not
exceed that which was registered) and any deviation from the low or high end of
the estimated maximum offering range may be reflected in the form of prospectus
filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the
changes in volume and price represent no more than 20% change in the maximum

                                       2
<PAGE>

aggregate offering price set forth in the "Calculation of Registration Fee"
table in the effective registration statement.

               (iii) 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.

     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.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 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 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 Act and will be governed by the final adjudication of
such issue.

after the date hereof prior to the filing of a post-effective amendment which
indicates that the securities offered hereby have been sold or which deregisters
the securities covered hereby then remaining unsold, shall also be deemed to be
incorporated by reference into this Registration Statement and to be a part
hereof from the date of delivery of such documents. Any statement contained in a
document incorporated or deemed to be incorporated by reference herein shall be
deemed to be modified or superseded for purposes of this Registration Statement
to the extent that a statement contained herein, or in any other subsequently

modifies or supersedes such statement. Any such statement so modified or
superseded shall not be deemed, except as so modified or superseded, to

ITEM 4.  DESCRIPTION OF SECURITIES

     Not applicable.

ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL

     The validity of the Common Stock registered pursuant hereto has been passed
upon by Linda S. Peterson, an Assistant General Counsel of the Registrant. Ms.
Peterson beneficially owns, and has rights to acquire under employee stock
options, an aggregate of less than 1% of the outstanding shares of Common Stock
of Occidental.

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, indemnity to directors
and officers under certain circumstances for liabilities incurred in connection
with their activities in such capacities (including

                                       1
reimbursement for expenses incurred). Occidental's Restated Certificate of
Incorporation provides for the elimination of personal liability of its
directors to the full extent permitted by the Delaware General Corporation Law
and Occidental has entered into indemnification agreements with each director
and certain officers providing for additional indemnification. Article VIII of
Occidental's By-laws provides that Occidental shall indemnify directors and
officers under certain circumstances for liabilities and expenses incurred by
reason of their activities in such capacities. In addition, Occidental has
insurance policies that provide liability coverage to directors and officers
while acting in such capacities.

         File No. 1-9210).

ITEM 9.  UNDERTAKINGS

     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 of 1933;

               (ii)  To reflect in the prospectus any facts or events arising
after the effective date of the 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 the registration
statement. Notwithstanding the foregoing, any increase or decrease in volume of
securities offered (if the total dollar value of securities offered would not
exceed that which was registered) and any deviation from the low or high end of
the estimated maximum offering range may be reflected in the form of prospectus
filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the
changes in volume and price represent no more than 20% change in the maximum

                                       2
aggregate offering price set forth in the "Calculation of Registration Fee"
table in the effective registration statement.

               (iii) 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.

     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.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 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 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 Act and will be governed by the final adjudication of
such issue.

                                       3
