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,

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 reimbursement for expenses incurred). Occidental's Restated Certificate of Incorporation, as amended, 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.

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 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.
