     Occidental Petroleum Corporation, a Delaware corporation (the "Company"),
confirms its agreement with Merrill Lynch & Co., Merrill Lynch, Pierce, Fenner &
Smith Incorporated, J.P. Morgan Securities Inc., BancAmerica Robertson Stephens,
Chase Securities Inc. and Morgan Stanley & Co. Incorporated (collectively the
"Underwriters," which term shall also include any underwriter substituted as
hereinafter provided in Section 11 hereof) with respect to the sale by the
Company and the purchase by the Underwriters, acting severally and not jointly,
of the respective principal amounts set forth opposite their names on Schedule A
hereto, of the Company's $250 million aggregate principal amount of 6.50% Senior
Notes due April 1, 2005 (the "Seven-Year Notes"), $200 million aggregate
principal amount of 7.20% Senior Debentures due April 1, 2028 (the "Thirty-Year
Debentures") and $450 million aggregate principal amount of 6.40% Senior Notes
due April 1, 2013, Mandatorily Tendered on April 1, 2003 (the "Mandatorily
Tendered Notes" and, together with the Seven-Year Notes and the Thirty-Year
Debentures, the "Notes"). The Notes are to be issued pursuant to an indenture
(the "Indenture", which term, for the purpose of this Agreement, shall include
the Officers' Certificate with respect to the Notes delivered pursuant to
Sections 201 and 301 of the Indenture), dated as of April 1, 1998, between the
Company and The Bank of New York, as trustee (the "Trustee").
 
     The Company has filed with the Securities and Exchange Commission (the
"Commission") a registration statement on Form S-3 (No. 33-59395) and, if
applicable, one or more amendments thereto for the registration of senior debt
securities, including the Notes, under the Securities Act of 1933, as amended
(the "1933 Act"), and the offering thereof from time to time in accordance with
Rule 415 of the rules and regulations of the Commission under the 1933 Act (the
"1933 Act Regulations"). Such registration statement
   2
 
(as amended, if applicable) has been declared effective by the Commission and
the Indenture has been qualified under the Trust Indenture Act of 1939, as
amended (the "1939 Act"). Such registration statement (as amended, if
applicable) and the prospectus constituting a part thereof, together with any
prospectus supplement relating to the Notes, including, in each case, all
Incorporated Documents (as hereinafter defined), are referred to herein as the
"Registration Statement" and the "Prospectus," respectively, except that, if any
revised prospectus or revised prospectus supplement shall be provided to the
Underwriters by the Company for use in connection with the offering of the Notes
that is not required to be filed by the Company pursuant to Rule 424(b) of the
1933 Act Regulations, the term "Prospectus" shall refer to such revised
prospectus or prospectus supplement, as the case may be, from and after the time
it is first provided to the Underwriters for such use. Any registration
statement filed pursuant to Rule 462(b) of the 1933 Act Regulations and relating
to the Registration Statement is herein referred to as the "Rule 462(b)
Registration Statement," and after such filing the term "Registration Statement"
shall include the Rule 462(b) Registration Statement. Any reference herein to
the Registration Statement, any preliminary prospectus or the Prospectus shall
be deemed to refer to and include the documents, financial statements and
schedules incorporated or deemed to be incorporated by reference therein
pursuant to Item 12 of Form S-3 under the 1933 Act, and any reference to any
amendment or supplement to the Registration Statement or the Prospectus shall be
deemed to refer to and include any documents, financial statements and schedules
filed by the Company with the Commission under the Securities Exchange Act of
1934, as amended (the "1934 Act"), and so incorporated or deemed to be
incorporated by reference (such incorporated documents, financial statements and
schedules being herein called the "Incorporated Documents"). Notwithstanding the
foregoing, for purposes of this Agreement any prospectus supplement prepared or
filed with respect to an offering pursuant to the Registration Statement of a
series of debt securities other than the Notes shall not be deemed to have
supplemented the Prospectus.
 
     For purposes of this Agreement, all references to the Registration
Statement, any preliminary prospectus or the Prospectus or any amendment or
supplement to any of the foregoing shall be deemed to include the copy filed
with the Commission pursuant to its Electronic Data Gathering, Analysis and
Retrieval system ("EDGAR").
 
     The Company understands that the Underwriters propose to make a public
offering of the Notes as soon as the Underwriters deem advisable after this
Agreement has been executed and delivered.
 
SECTION 1.  Representations and Warranties.
 
     (a) The Company represents and warrants to each of the Underwriters as
follows:
 
          (i) The Incorporated Documents, when they were filed or became
     effective (or, if an amendment with respect to any such Incorporated
     Document was filed or became effective, when such amendment was filed or
     became effective) with the Commission, as the case may be, complied in all
     material respects with the requirements of the 1934 Act and the rules and
     regulations of the Commission under the 1934 Act (the "1934 Act
     Regulations"), and any Incorporated Documents filed subsequent to the date
     hereof and prior to the termination of the offering of the Notes, will,
     when they are filed with the Commission, comply in all material respects
     with the requirements of the 1934 Act and the 1934 Act Regulations; no such
     Incorporated Document, when it was filed or became effective (or, if an
     amendment with respect to any such Incorporated Document was filed or
     became effective, when such amendment was filed or became effective) with
     the Commission, contained, and no Incorporated Document filed subsequent to
     the date hereof and prior to the termination of the offering of the Notes
     will contain, an untrue statement of a material fact or omitted, or will
     omit, to state a material fact required to be stated therein or necessary
     to make the statements therein, in the light of the circumstances under
     which they were or will be made, not misleading.
 
          (ii) Each preliminary prospectus relating to the Notes filed as part
     of the Registration Statement as originally filed or as part of any
     amendment thereto, or filed pursuant to Rule 424 of the 1933 Act
     Regulations, when so filed, and the Registration Statement and the Rule
     462(b) Registration Statement, at the respective times they became
     effective, complied in all material respects with the provisions of the
     1933 Act and the 1933 Act Regulations; at the date hereof and at the
     Closing Time, the Registration
 
                                        2
   3
 
     Statement, the Rule 462(b) Registration Statement and the Prospectus, and
     any supplement or amendment thereto relating to the Notes, comply and will
     comply in all material respects with the provisions of the 1933 Act and the
     1933 Act Regulations; and the Registration Statement, the Rule 462(b)
     Registration Statement and the Prospectus, and any such supplement or
     amendment thereto relating to the Notes, at all such times did not and will
     not contain an untrue statement of a material fact or omit to state a
     material fact required to be stated therein or necessary to make the
     statements therein, in the light of the circumstances under which they were
     made, not misleading; except that this representation and warranty does not
     apply to statements or omissions in the Registration Statement, the Rule
     462(b) Registration Statement, the Prospectus or any preliminary
     prospectus, or any amendment or supplement thereto, made in reliance upon
     information furnished to the Company in writing by or on behalf of any
     Underwriter expressly for use therein or to those parts of the Registration
     Statement that constitute the Trustee's Statement of Eligibility on Form
     T-1 under the 1939 Act (the "Form T-1"). There is no contract or document
     of a character required to be described in the Registration Statement or
     the Prospectus or to be filed as an exhibit to the Registration Statement
     that is not described or filed as required. In the event that the
     Registration Statement (including any prospectus filed as part of the
     Registration Statement), the Rule 462(b) Registration Statement, any
     preliminary prospectus or the Prospectus or any amendment or supplement to
     any of the foregoing was or is filed electronically pursuant to EDGAR, then
     the Registration Statement (including any prospectus filed as part
     thereof), the Rule 462(b) Registration Statement, such preliminary
     prospectus, the Prospectus and any such amendment or supplement delivered
     to the Underwriters for use in connection with the offering of the Notes
     was or will be, as the case may be, identical (as to content) to the
     electronically transmitted copy thereof filed with the Commission pursuant
     to EDGAR, except to the extent permitted by Regulation S-T.
 
          (iii) This Agreement, the Indenture, the Remarketing Agreement (the
     "Remarketing Agreement"), dated as of April 1, 1998, between the Company
     and Merrill Lynch, Pierce, Fenner & Smith Incorporated (the "Remarketing
     Dealer") and the Notes have been duly authorized by the Company and conform
     in all material respects to the descriptions thereof in the Prospectus.
 
          (iv) The Indenture (assuming the due execution and delivery thereof by
     the Trustee) and the Remarketing Agreement are, and the Notes (when
     executed by the Company and authenticated in accordance with the Indenture
     and delivered to and paid for by the purchasers thereof) will be, the
     legal, valid and binding obligations of the Company, enforceable against
     the Company in accordance with their terms, except as such enforceability
     may be limited by (A) bankruptcy, insolvency, reorganization, moratorium or
     other similar laws now or hereafter in effect relating to or affecting the
     enforcement of creditors' rights generally and (B) general principles of
     equity (regardless of whether such enforcement is considered in a
     proceeding in equity or at law). The Notes (when executed by the Company
     and authenticated in accordance with the terms of the Indenture and
     delivered to and paid for by the purchasers thereof) will be entitled to
     the benefits of the Indenture (subject to the exceptions set forth in the
     preceding sentence).
 
          (v) The Company and each of Occidental Chemical Holding Corporation, a
     California corporation, and Occidental Oil and Gas Corporation, a
     California corporation (each a "Principal Domestic Subsidiary" and
     collectively the "Principal Domestic Subsidiaries") is a validly existing
     corporation in good standing under the laws of its state of incorporation.
     The Company and each Principal Domestic Subsidiary has full corporate power
     and authority to own its properties and carry on its business as presently
     conducted, as described in the Prospectus, and is duly registered or
     qualified to conduct business, and is in good standing, in each
     jurisdiction in which it owns or leases property or transacts business and
     in which such registration or qualification is necessary, except as to
     jurisdictions where the failure to do so would not have a material adverse
     effect on the Company and its subsidiaries, taken as a whole. All of the
     outstanding capital stock or other securities evidencing equity ownership
     of each Principal Domestic Subsidiary has been duly and validly authorized
     and issued and is fully paid and non-assessable, and is owned by the
     Company, directly or indirectly through subsidiaries, free and clear of any
     security interest, claim, lien or encumbrance. There are no outstanding
     rights, warrants or options to
 
                                        3
   4
 
     acquire, or instruments convertible into or exchangeable for, any shares of
     capital stock or other equity interest in any such Principal Domestic
     Subsidiary, except for rights, warrants or options held by the Company.
 
          (vi) Except as contemplated in the Prospectus or reflected therein by
     the filing of any amendment or supplement thereto or any Incorporated
     Document, since the date of the most recent consolidated financial
     statements included or incorporated by reference in the Registration
     Statement and the Prospectus, unless the Company has notified the
     Underwriters as provided in Section 4(d) hereof, there has not been any
     material adverse change in the consolidated financial condition of the
     Company and its subsidiaries, taken as a whole.
 
          (vii) The Company is not in violation of its Restated Certificate of
     Incorporation or Bylaws, in each case, as amended. The execution and
     delivery of this Agreement and the Remarketing Agreement by the Company,
     the issuance and sale of the Notes and the performance by the Company of
     its obligations under this Agreement, the Remarketing Agreement and the
     Indenture will not conflict with or constitute a breach of or a default
     (with the passage of time or otherwise) under (A) the Restated Certificate
     of Incorporation or Bylaws of the Company, in each case, as amended, (B)
     any agreement or instrument (which is, individually or in the aggregate,
     material to the Company and its subsidiaries, taken as a whole) to which
     the Company is a party or by which it is bound or (C) any order of any
     court or governmental agency or authority presently in effect and
     applicable to the Company or any Principal Domestic Subsidiary. Except for
     orders, permits and similar authorizations required under the securities or
     Blue Sky laws of certain jurisdictions, including jurisdictions outside the
     United States, or required of any securities exchange on which any of the
     Notes might be listed, no consent, approval, authorization or other order
     of any regulatory body, administrative agency or other governmental body is
     legally required for the valid issuance and sale of the Notes.
 
          (viii) To the best of the Company's knowledge, the accountants who
     have audited and reported upon the consolidated financial statements filed
     with the Commission as part of the Registration Statement and the
     Prospectus are independent accountants as required by the 1933 Act. The
     consolidated financial statements included in the Registration Statement
     and Prospectus, or incorporated therein by reference, fairly present the
     consolidated financial position and results of operations of the entities
     to which such statements relate at the respective dates and for the
     respective periods to which they apply. Such consolidated financial
     statements have been prepared in accordance with generally accepted
     accounting principles consistently applied, except as set forth in the
     Registration Statement and Prospectus.
 
          (ix) The Company has complied with, and is and will be in compliance
     with, the provisions of that certain Florida act relating to disclosure of
     doing business with Cuba, codified as Section 517.075 of the Florida
     statutes, and the rules and regulations thereunder (collectively, the "Cuba
     Act") or is exempt therefrom.
 
     (b) Additional Certifications.  Any certificate signed by any officer of
the Company and delivered to the Underwriters or to counsel for the Underwriters
in connection with transactions contemplated hereby shall be deemed a
representation and warranty by the Company to such Underwriters as to the
matters covered thereby on the date of such certificate.
 
SECTION 2.  Sale and Delivery to the Underwriters; Closing.
 
     (a) Purchase and Sale.  On the basis of the representations and warranties
herein contained and subject to the terms and conditions herein set forth, the
Company agrees to issue and sell to each Underwriter, severally and not jointly,

as shall be agreed upon by the Underwriters and the Company, at 10:00 a.m., New
York City time, on April 6, 1998 (unless postponed in accordance with the
provisions of Section 11), or such other time not later than ten business days

such Underwriter has agreed to purchase. The certificates for the Notes will be
made available for examination and packaging by the Underwriters not later than

     supplementary listing particulars or any other document required or
     permitted to be published by listing rules under Part IV of the Financial
     Services Act, to a person who is of a kind described in Article 11(3) of
     the Financial Services Act 1986 (Investment Advertisements) (Exemptions)
     Order 1996 or is a person to whom such document may otherwise lawfully be
     issued or passed on.
 
          (iii) With respect to Japan, each Underwriter understands that the
     Notes have not been, and will not be, registered under the Securities and
     Exchange Law of Japan, and, accordingly, each Underwriter, severally and

   6
 
     indirectly, offer or sell, any of the Notes in Japan or to any resident of
     Japan (including any corporation or other entity incorporated or organized
     under the laws of Japan), or to others for re-offering or resale, directly
     or indirectly, in Japan or to any such resident of Japan, except, in each
     case, in compliance in all material respects with the Securities and
     Exchange Law of Japan, and (B) with respect to any such sale of the Notes
     made by such Underwriter, such Underwriter will effect all necessary
     filings in connection with such sale, including, without limitation, any
     required filings of notifications with the Minister of Finance of Japan, as

     any of the Provinces after the date (the "Canadian Ending Date") set by the
     Company for the end of the offer of such Notes, and, without the prior
     written consent of the Company, such Underwriter will not distribute or

     when such offer or sale is made, provided that such offer or sale is made

SECTION 4.  Covenants of the Company.
 
     The Company covenants with each Underwriter as follows:
 
     (a) Notice of Certain Events.  During the period from the date hereof to

Company will notify the Underwriters promptly (i) of the effectiveness of any
post-effective amendment to the Registration Statement, (ii) of the receipt of
any comments from the Commission with respect to the Registration Statement, the
Rule 462(b) Registration Statement or the Prospectus, (iii) of any request by
the Commission for any amendment to the Registration Statement or the Rule
462(b) Registration Statement or any amendment or supplement to the Prospectus
or for additional information and (iv) of the issuance by the Commission of any
stop order suspending the effectiveness of the Registration Statement or the
Rule 462(b) Registration Statement or the initiation of any proceedings for that
purpose. The Company will make every reasonable effort to prevent the issuance
of any such stop order and, if any such stop order is issued, to obtain the
lifting thereof at the earliest possible moment.
 
                                        6
   7
 
     (b) Proposed Filings.  During the period from the date hereof to and
including the Closing Time, the Company will not file any amendment or
supplement to the Registration Statement or the Rule 462(b) Registration
Statement, or file any amendment or supplement to the Prospectus, in any such
case relating to the Notes, of which the Underwriters shall not previously have
been advised or to which the Underwriters shall reasonably object in writing,
unless, in the judgment of the Company and its counsel, such amendment or
supplement is necessary to comply with law.
 
     (c) Copies of the Registration Statement, the Rule 462(b) Registration
Statement and the Prospectus.  The Company will deliver to each of the
Underwriters one signed and as many conformed copies of the Registration
Statement (as originally filed), the Rule 462(b) Registration Statement and of
each amendment thereto relating to the Notes (including the Incorporated
Documents and any exhibits filed therewith or incorporated by reference therein)
as the Underwriters may reasonably request. The Company will furnish to the
Underwriters as many copies of the Prospectus (as amended or supplemented) as
the Underwriters shall reasonably request so long as the Underwriters are
required to deliver a Prospectus in connection with sales or solicitations of
offers to purchase the Notes.
 
     (d) Revisions of Prospectus -- Material Changes.  So long as the
Underwriters are required to deliver a Prospectus in connection with sales or
solicitations of offers to purchase the Notes, if any event shall occur or
condition exist as a result of which it is necessary, in the opinion of counsel
for the Company and of counsel for the Underwriters, to further amend or
supplement the Prospectus in order that the Prospectus will not include an
untrue statement of a material fact or omit to state any material fact necessary
in order to make the statements therein not misleading, in the light of the
circumstances existing at the time it is delivered to a purchaser, or if it
shall be necessary, in the opinion of such counsel, to amend or supplement the
Registration Statement or the Prospectus in order to comply with the
requirements of the 1933 Act or the 1933 Act Regulations, prompt notice shall be
given to the Underwriters, and the Company will promptly prepare and file an
amendment or supplement to the Prospectus so that the Prospectus, as amended or
supplemented, will not include any untrue statement of a material fact or omit
to state any material fact necessary in order to make the statements therein not
misleading, in the light of the circumstances existing at the time it is
delivered to the Underwriters.
 
     (e) Earnings Statements.  The Company will make generally available to its
security holders a consolidated earnings statement (which need not be audited)
covering a period of at least twelve months commencing after the Closing Time
(but in no event commencing later than 90 days after the Closing Time), as soon
as is reasonably practicable after the end of such period, which earnings
statement shall satisfy the provisions of Section 11(a) and Rule 158 of the 1933
Act.
 
     (f) Blue Sky Qualifications.  The Company will endeavor, in cooperation
with the Underwriters, to qualify the Notes for offering and sale under the
applicable securities laws of such states and other jurisdictions as the
Underwriters may reasonably designate (provided no registration shall be
required in any jurisdiction outside the United States), and will maintain such
qualifications in effect for as long as may be required for the distribution of
the Notes; provided, however, that the Company will promptly notify the
Underwriters of any suspension of any such qualifications; and provided,
further, that the Company shall not be obligated to register or qualify as a
foreign corporation or take any action which would subject it to general service
of process in any jurisdiction where it is not now so subject.
 
     (g) Filing of Prospectus. Immediately following the execution and delivery
of this Agreement, the Company will prepare and file or transmit for filing with
the Commission in accordance with Rule 424(b) of the 1933 Act Regulations,
copies of a supplement to the Prospectus containing the terms of the Notes and
such other information as the Underwriters and the Company deem appropriate.
 
SECTION 5. Payment of Expenses.
 
     The Company will pay all expenses incident to the performance of its

(otherwise than by notice given by the Underwriters in connection with the
occurrence of any event set forth in clauses (ii) through (iv) of Section 10(a)
or pursuant to Section 11), the Company shall reimburse the Underwriters for all
of their out-of-pocket expenses, including the reasonable fees and disbursements
of counsel for the Underwriters.
 
SECTION 6.  Conditions of Underwriters' Obligations.
 
     The obligations of the Underwriters hereunder are subject to the accuracy
of the representations and warranties on the part of the Company herein and the

by the Company of all covenants and agreements herein contained on its part to
be performed and observed and to the following additional conditions precedent:

any of the Underwriters, contemplated by the Commission; no stop order
suspending the sale of the Notes in any jurisdiction designated by the

     (b) The Underwriters shall have received an opinion from Robert E. Sawyer,
Esq., Associate General Counsel for the Company, dated as of the Closing Time
and in form and substance satisfactory to counsel for the Underwriters, to the
effect that:
 
          (i) The Company has been duly incorporated and is validly existing in
     good standing under the laws of the State of Delaware. Each Principal
     Domestic Subsidiary is validly existing in good standing under the laws of
     its state of incorporation.

     enter into and perform its obligations under this Agreement and the

   9
 
          (iv) The Indenture and the Remarketing Agreement have been duly
     authorized, executed and delivered by the Company and (assuming the due
     authorization, execution and delivery of the Indenture and the Remarketing
     Agreement by the Trustee and the Remarketing Dealer, respectively) are
     valid and binding agreements of the Company enforceable against the Company
     in accordance with their terms, except that such enforceability may be
     limited by (A) bankruptcy, insolvency, reorganization, moratorium or other
     similar laws now or hereafter in effect relating to creditors' rights
     generally, (B) general principles of equity (regardless of whether
     enforcement is sought in a proceeding in equity or at law) and (C) in the
     case of the Remarketing Agreement any law limiting rights of indemnity or
     contribution.
 
          (v) No consent or approval of any United States governmental authority
     or other United States person or United States entity is required in
     connection with the issuance or sale of the Notes other than registration
     thereof under the 1933 Act, qualification of the Indenture under the 1939
     Act, and such registrations or qualifications as may be necessary under the
     securities or Blue Sky laws of the various United States jurisdictions in
     which the Notes are to be offered or sold.
 
          (vi) The Notes have been duly authorized by the Company and, when
     executed by the Company and authenticated by the Trustee in accordance with
     the terms of the Indenture (assuming the due authorization, execution and
     delivery of the Indenture by the Trustee) and issued to and paid for by the
     Underwriters in accordance with the terms of this Agreement, will be
     entitled to the benefits of the Indenture and will be valid and binding
     obligations of the Company enforceable against the Company in accordance
     with their respective terms, except that such enforceability may be limited
     by (A) bankruptcy, insolvency, reorganization, moratorium or other similar
     laws now or hereafter in effect relating to creditors' rights generally and
     (B) general principles of equity (regardless of whether such enforcement is
     sought in a proceeding in equity or at law).
 
          (vii) The Registration Statement, including any Rule 462(b)
     Registration Statement, has become effective under the 1933 Act and the
     Indenture has been qualified under the 1939 Act, and, to the best of such
     counsel's knowledge, no stop order suspending the effectiveness of the
     Registration Statement or any Rule 462(b) Registration Statement has been
     issued and no proceedings for that purpose have been instituted or are
     pending or contemplated.
 
          (viii) The execution and delivery of this Agreement, the Remarketing
     Agreement and the Indenture by the Company, the issuance and sale of the
     Notes and the fulfillment of this Agreement, the Remarketing Agreement and
     the Indenture by the Company will not conflict with or constitute a breach
     of or a default (with the passage of time or otherwise) under (A) the
     Restated Certificate of Incorporation or Bylaws of the Company, in each
     case, as amended, (B) any statute, law or regulation to which the Company
     or any Principal Domestic Subsidiary or any of their respective properties
     may be subject or (C) any judgment, decree or order, known to such counsel,
     after reasonable inquiry, of any court or governmental agency or authority
     entered in any proceeding to which the Company or any Principal Domestic
     Subsidiary was or is now a party or by which it is bound, except that such
     counsel may state that the opinion set forth in clause (B) of this
     paragraph (viii) is limited to those statutes, laws or regulations in
     effect on the date of such opinion which, in such counsel's experience, are
     normally applicable to transactions of the type contemplated by this
     Agreement and that such counsel expresses no opinion as to the securities
     or Blue Sky laws of the various jurisdictions in which the Notes are to be
     offered.
 
          (ix) The Registration Statement and the Rule 462(b) Registration
     Statement, as of their respective effective dates, and the Prospectus, as
     of its date, including each Incorporated Document when such Incorporated
     Document was filed or became effective, or if any such Incorporated
     Document was amended, when such amendment was filed or became effective,
     appeared on their face to be appropriately responsive in all material
     respects to the applicable requirements of the 1933 Act or the 1934 Act, as
     the case may be, except that in each case such counsel need not express an
     opinion as to the financial statements and schedules and other financial
     data included or incorporated by reference therein or as to the Form T-1.
 
          (x) The statements in the Prospectus under the captions "Description
     of the Debt Securities" and "Description of the Notes," insofar as they
     purport to summarize certain provisions of documents specifically referred
     to therein, are in all material respects accurate summaries of such
     provisions.
 
                                        9
   10
 
          (xi) Except as set forth in the Prospectus (including the Incorporated
     Documents), there is not pending or, to the knowledge of such counsel,
     after reasonable inquiry, threatened any action, suit or proceeding against
     the Company or any of its subsidiaries before or by any court or
     governmental agency or body, which is likely (to the extent not covered by
     insurance) to have a material adverse effect on the consolidated financial
     condition of the Company and its subsidiaries, taken as a whole.
 
          (xii) To the best of such counsel's knowledge, after reasonable
     inquiry, there is no contract or document of a character required to be
     described in the Registration Statement or the Prospectus or to be filed as
     an exhibit to the Registration Statement that is not described or filed as
     required.
 
          (xiii) To the best of such counsel's knowledge, after reasonable
     inquiry, the Company is not in violation of its Restated Certificate of
     Incorporation or Bylaws, in each case, as amended.
 
          (xiv) To the best of such counsel's knowledge, after reasonable
     inquiry, the execution and delivery of this Agreement, the Remarketing
     Agreement and the Indenture by the Company, the issuance and sale of the
     Notes and the performance by the Company of its obligations under this
     Agreement, the Remarketing Agreement and the Indenture will not conflict
     with or constitute a breach of or a default (with the passage of time or
     otherwise) under any agreement or instrument that is, individually or in
     the aggregate, material to the Company and its subsidiaries, taken as a
     whole, to which the Company is a party or by which it is bound.
 
          In rendering such opinion such counsel may state that with respect to
     certain matters he has relied upon advice of other counsel employed by the
     Company who are more familiar with such matters.
 
          In addition, such counsel shall state that he has participated in
     conferences with officers and other representatives of the Company, outside
     counsel for the Company, representatives of the independent public
     accountants for the Company, representatives of the Underwriters and
     counsel for the Underwriters, at which conferences the contents of the
     Registration Statement, the Rule 462(b) Registration Statement and
     Prospectus and related matters were discussed and, although he is not
     passing upon, and does not assume any responsibility for the accuracy,
     completeness or fairness of the statements contained in the Registration
     Statement, the Rule 462(b) Registration Statement or the Prospectus (other
     than as set forth in paragraph (x) above) and has not made any independent
     check or verification thereof, on the basis of the foregoing, nothing has
     come to such counsel's attention that leads him to believe that either the
     Registration Statement (including the Incorporated Documents) at the time
     such Registration Statement became effective, and if an amendment to the
     Registration Statement or an Annual Report on Form 10-K has been filed by
     the Company with the Commission subsequent to the effectiveness of the
     Registration Statement and prior to the date of such statement, then at the
     time such amendment became effective or at the time of the most recent such
     filing (to the extent deemed to be incorporated by reference therein), or
     the Rule 462(b) Registration Statement at the time such Rule 462(b)
     Registration Statement became effective contained an untrue statement of a
     material fact or omitted to state a material fact required to be stated
     therein or necessary to make the statements therein not misleading, or that
     the Prospectus (including the Incorporated Documents) as of its date and as
     of the Closing Time contained or contains an untrue statement of a material
     fact or omitted or omits to state a material fact necessary to make the
     statements therein, in the light of the circumstances under which they were
     made, not misleading, except that such counsel need express no opinion with
     respect to the financial statements, schedules and other financial data
     included or incorporated by reference in the Registration Statement, the
     Rule 462(b) Registration Statement or Prospectus or with respect to the
     Form T-1.
 
     (c) The Underwriters shall have received an opinion from Brown & Wood LLP,
counsel to the Underwriters, dated as of the Closing Time and in form and
substance satisfactory to the Underwriters.
 
     (d) Officer's Certificate. Except as contemplated in the Prospectus or
reflected therein by the filing of any amendment or supplement thereto or any
Incorporated Document, at the Closing Time, there shall not have been, since the
date of the most recent consolidated financial statements included or
incorporated by reference in the Prospectus, any material adverse change in the
consolidated financial condition of the Company and its subsidiaries, taken as a
whole. The Underwriters shall have received a certificate signed by an officer
of the Company, dated as of the Closing Time, to the effect (i) that there has
been no such material adverse change, (ii) that the representations and
warranties of the Company contained in Section 1(a) hereof
 
                                       10
   11
 
(other than Section 1(a)(vi)) are true and correct in all material respects with
the same force and effect as though expressly made at and as of the date of such
certificate, (iii) that the Company has complied with all agreements and
satisfied all conditions required by this Agreement or the Indenture on its part
to be performed or satisfied at or prior to the date of such certificate and
(iv) that no stop order suspending the effectiveness of the Registration
Statement has been issued and, to the best of such officer's knowledge, no
proceedings for that purpose have been initiated or threatened by the
Commission.
 
     (e) Comfort Letter. On the date hereof, the Underwriters shall have
received a letter from the Company's independent public accountants, dated as of
the date hereof and in form and substance satisfactory to the Underwriters,
containing statements and information of a type ordinarily included in
accountants' "comfort letters" to underwriters with respect to the financial
statements and certain financial information contained or incorporated by
reference in the Registration Statement and the Prospectus; and, if financial
statements for any assets, business or entity acquired by the Company are
included or incorporated by reference in the Registration Statement or the
Prospectus, the Underwriters shall have received a similar "comfort letter" from
a firm of independent public accountants, dated as of the date hereof and in
form and substance satisfactory to the Underwriters, with respect to such
financial statements and any financial information with respect to such assets,
business or entity, as the case may be, contained or incorporated by reference
in the Registration Statement and the Prospectus. Without limitation to the
foregoing, the letter delivered by the Company's independent public accountants
shall state that nothing has come to their attention that caused them to believe
that at a specified date not more than five days prior to the date of such
letter, there was any change in the outstanding capital stock of the Company or
any increase in consolidated long-term debt of the Company or any decrease in
the stockholders' equity of the Company, in each case as compared with the
amounts shown on the most recent consolidated balance sheet of the Company
incorporated by reference in the Registration Statement and Prospectus or,
during the period from the date of such balance sheet to a specified date not
more than five days prior to the date of such letter, there were any decreases,
as compared with the corresponding period in the preceding year, in consolidated
net sales and operating revenues or net income of the Company, except in each
such case as set forth in or contemplated by the Registration Statement and
Prospectus or except for such exceptions enumerated in such letter as shall have
been agreed to by the Underwriters and the Company.
 
     (f) Subsequent Delivery of Comfort Letter.  At the Closing Time, the
Underwriters shall have received from each firm of independent public
accountants which delivered a letter pursuant to subsection (e) of this Section,
a letter, dated as of the Closing Time, to the effect that they reaffirm the
statements made in the letter furnished pursuant to subsection (e) of this
Section, except that the specified date referred to shall be a date not more
than five days prior to the Closing Time.
 
     (g) Other Documents.  At the Closing Time, counsel for the Underwriters
shall have been furnished with resolutions of the Company's Board of Directors
authorizing and approving the issuance and sale of the Notes and matters related
thereto and such other documents and opinions as they may reasonably require for
the purpose of enabling them to pass upon the issuance and sale of the Notes as
herein contemplated and related proceedings, or in order to evidence the
accuracy of any of the representations or warranties, or the fulfillment of any
of the conditions, herein contained.
 
     (h) Tax Opinion.  The Underwriters shall have received an opinion from
Skadden, Arps, Slate, Meagher & Flom LLP, counsel for the Company, dated as of
the Closing Time and in form and substance satisfactory to counsel for the
Underwriters, to the effect that although the discussion in the Prospectus under
the captions "United States Taxation" and "Certain United States Federal Tax
Considerations" do not purport to discuss all possible United States federal
income tax consequences of the purchase, ownership, and disposition of the
Notes, in the opinion of such counsel, such discussions together constitute, in
all material respects, a fair and accurate summary of the United States federal
income tax consequences of the purchase, ownership, and disposition of the
Notes, based upon current law and subject to the qualifications set forth
therein.
 
     If any condition specified in this Section 6 shall not have been fulfilled
when and as required to be fulfilled, this Agreement may be terminated by any of
the Underwriters by notice to the Company at any time at or prior to the Closing
Time, and any such termination shall be without liability of any party to any
other
 
                                       11
   12
 
party, except as provided in Section 5, and except that the indemnity and
contribution agreements set forth in Sections 7 and 8 hereof and the provisions
of Section 9 hereof shall remain in effect.
 
SECTION 7.  Indemnification.
 
     (a) Indemnification of the Underwriters.  The Company agrees to indemnify
and hold harmless each Underwriter and each person, if any, who controls an
Underwriter within the meaning of Section 15 of the 1933 Act as follows:
 
          (i) against any and all loss, liability, claim, damage and expense
     whatsoever (including, subject to the limitations set forth in subsection
     (c) below, the reasonable fees and disbursements of counsel chosen by the
     Underwriters), as incurred, insofar as such loss, liability, claim, damage
     or expense arises out of any untrue statement or alleged untrue statement
     of a material fact contained in the Registration Statement or the omission
     or alleged omission therefrom of a material fact required to be stated
     therein or necessary to make the statements therein not misleading, or
     arises out of any untrue statement or alleged untrue statement of a
     material fact contained in the Prospectus or the omission or alleged
     omission therefrom of a material fact necessary in order to make the
     statements therein, in the light of the circumstances under which they were
     made, not misleading;
 
          (ii) against any and all loss, liability, claim, damage and expense
     whatsoever (including, subject to the limitations set forth in subsection
     (c) below, the reasonable fees and disbursements of counsel chosen by the
     Underwriters), as incurred, to the extent of the aggregate amount paid in
     settlement of any litigation, or investigation or proceeding by any
     governmental agency or body, commenced or threatened, or of any claim
     whatsoever, insofar as such loss, liability, claim, damage or expense
     arises out of any such untrue statement or omission, or any such alleged
     untrue statement or omission, if such settlement is effected with the
     written consent of the Company; and
 
          (iii) against any and all expense whatsoever (including, subject to
     the limitations set forth in subsection (c) below, the reasonable fees and
     disbursements of counsel chosen by the Underwriters), as incurred,
     reasonably incurred in investigating, preparing or defending against any
     litigation, or investigation or proceeding by any governmental agency or
     body, commenced or threatened, or any claim whatsoever, based upon any such
     untrue statement or omission, or any such alleged untrue statement or
     omission;
 
provided, however, that this indemnity shall not apply to any loss, liability,
claim, damage or expense (A) to the extent arising out of or based upon any
untrue statement or omission or alleged untrue statement or omission made in
reliance upon the Form T-1 under the 1939 Act filed as an exhibit to the
Registration Statement; or (B) to the extent arising out of any untrue statement
or omission or alleged untrue statement or omission in the Prospectus, if such
untrue statement or alleged untrue statement or omission or alleged omission is
corrected in an amendment or supplement to the Prospectus and if, having
previously been furnished by or on behalf of the Company with copies of the
Prospectus, as so amended or supplemented, such Underwriter thereafter failed to
deliver such Prospectus, as so amended or supplemented, prior to or concurrently
with the sale of a Note or Notes to the person asserting such loss, liability,
claim, damage or expense who purchased such Note or Notes that are the subject
thereof from such Underwriter; or (C) as to which such Underwriter may be
required to indemnify the Company pursuant to the provisions of subsection (b)
of this Section 7; or (D) if such loss, liability, claim, damage or expense is
covered by any other written agreement between the Company and such Underwriter
pertaining to the sale of the Notes pursuant to which such Underwriter may be
required to indemnify the Company for such loss, liability, claim, damage or
expense.
 
     (b) Indemnification of the Company.  Each Underwriter agrees, severally and
not jointly, to indemnify and hold harmless the Company, its directors, each of
its officers who signed the Registration Statement, and each person, if any, who
controls the Company within the meaning of Section 15 of the 1933 Act against
any and all loss, liability, claim, damage and expense described in the
indemnity contained in subsection (a) of this Section 7, as incurred, but only
with respect to untrue statements or omissions, or alleged untrue statements or
omissions, made in the Registration Statement or the Prospectus in reliance upon
and in
 
                                       12
   13
 
conformity with written information furnished to the Company by or on behalf of
any such Underwriter expressly for use in the Registration Statement or the
Prospectus.
 
     (c) General.  (i) In case any action, suit or proceeding (including any
governmental or regulatory investigation or proceeding) shall be brought against
any Underwriter or any person controlling such Underwriter, based upon the
Registration Statement or the Prospectus and with respect to which indemnity may
be sought against the Company pursuant to this Section 7, such Underwriter or
controlling person shall promptly notify the Company in writing, and the Company
shall assume the defense thereof, including the employment of counsel and
payment of all expenses. Any such Underwriter or any such controlling person
shall have the right to employ separate counsel in any such action, suit or
proceeding and to participate in the defense thereof, but the fees and expenses
of such separate counsel shall be at the expense of such Underwriter or such
controlling person, unless (A) the employment of such counsel shall have been
specifically authorized in writing by the Company, (B) the Company shall have
failed to assume the defense and employ counsel or (C) the named parties to any
such action, suit or proceeding (including any impleaded parties) shall include
both such Underwriter or such controlling person and the Company, and such
Underwriter or such controlling person shall have been advised by such counsel
that there may be one or more legal defenses available to it that are different
from, or additional to, those available to the Company (in which case, if such
Underwriter or such controlling person notifies the Company in writing that it
elects to employ separate counsel at the expense of the Company, the Company
shall not have the right to assume the defense of such action, suit or
proceeding on behalf of such Underwriter or such controlling person, it being
understood, however, that the Company shall not, in connection with any one such
action or separate but substantially similar or related actions in the same
jurisdiction arising out of the same general allegations or circumstances, be
liable for the reasonable fees and expenses of more than one separate firm of
attorneys (in addition to any local counsel) for all such Underwriters and such
controlling persons, which firm shall be designated in writing by a majority of
all such Underwriters, on behalf of all of such Underwriters and such
controlling persons).
 
     (ii) In case any action, suit or proceeding (including any governmental or
regulatory investigation or proceeding) shall be brought against the Company,
any of the Company's directors or officers, or any person controlling the
Company, with respect to which indemnity may be sought against any Underwriter
pursuant to this Section 7, such Underwriter shall have the rights and duties
given to the Company by subsection (c)(i) of this Section 7, and the Company,
the Company's directors and officers and any such controlling person shall have
the rights and duties given to the Underwriters by subsection (c)(i) of this
Section 7.
 
SECTION 8.  Contribution.
 
     In order to provide for just and equitable contribution in circumstances in
which the indemnity agreement provided for in Section 7 hereof is for any reason
held to be unenforceable by the indemnified parties, although applicable in
accordance with its terms, the Company and each Underwriter shall contribute to
the aggregate losses, liabilities, claims, damages and expenses of the nature
contemplated by said indemnity agreement incurred by the Company and the
Underwriters, as incurred, (i) in such proportion as is appropriate to reflect
the relative benefits received by the Company, on the one hand, and each of the
Underwriters, on the other hand, from the offering of the Notes or (ii) if the
allocation provided by clause (i) above is not permitted by applicable law, in
such proportion as is appropriate to reflect not only the relative benefits
referred to in clause (i) above but also the relative fault of the Company, on
the one hand, and of the Underwriters, on the other hand, in connection with the
statements or omissions that resulted in such losses, liabilities, claims,
damages and expenses. The relative benefits received by the Company, on the one
hand, and the Underwriters, on the other hand, shall be deemed to be in the same
proportions as the total net proceeds from the sale of the Notes (before
deducting expenses) received by the Company, on the one hand, and the total
underwriting discounts and commissions received by each Underwriter, on the
other hand, bear to the total price to public of the Notes as set forth in the
table on the cover page of the Prospectus. The relative fault of the Company, on
the one hand, and the Underwriters, on the other hand, shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Company or by the Underwriters and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission. The
 
                                       13
   14
 
Underwriters' respective obligations to contribute pursuant to this Section 8
are several in proportion to the respective numbers of Notes they have purchased
hereunder, and not joint. Notwithstanding the provisions of this Section 8, no
Underwriter shall be required to contribute any amount in excess of the amount
by which the total price at which the Notes underwritten by it and distributed
by the public were offered to the public exceeds the amount of any damages that
such Underwriter has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission. No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933
Act) shall be entitled to contribution from any person who was not guilty of
such fraudulent misrepresentation. For purposes of this Section 8, each person,
if any, who controls an Underwriter within the meaning of Section 15 of the 1933
Act shall have the same rights to contribution as such Underwriter, and each
director of the Company, each officer of the Company who signed the Registration
Statement and each person, if any, who controls the Company within the meaning
of Section 15 of the 1933 Act shall have the same rights to contribution as the
Company. Any party entitled to contribution hereunder will, promptly after
receipt of notice of commencement of any action, suit or proceeding against such
party in respect of which a claim for contribution may be made against another
party or parties under this Section 8, notify such party or parties from whom
contribution may be sought, but the omission to so notify such party or parties
shall not relieve the party or parties from whom contribution may be sought from
any other obligation it or they may have otherwise than under this Section 8.
 
SECTION 9.  Representations, Warranties and Agreements to Survive Delivery.
 
     All representations, warranties and agreements contained in this Agreement,
or contained in certificates of officers of the Company submitted pursuant
hereto, shall remain operative and in full force and effect, regardless of any
investigation made by or on behalf of any Underwriter or any controlling person
of any Underwriter, or by or on behalf of the Company, and shall survive each
delivery of and payment for any of the Notes.
 
SECTION 10.  Termination.
 
     (a) The Underwriters may terminate this Agreement, by notice to the
Company, at any time at or prior to the Closing Time if (i) between the date
hereof and the Closing Date, there shall have been any material adverse change
in the consolidated financial condition of the Company and its subsidiaries,
taken as a whole, (ii) there shall have occurred any material adverse change in
the financial markets in the United States or any outbreak or escalation of
hostilities or other national or international calamity or crisis, the effect of
which shall be such as to make it, in the reasonable judgment of the
Underwriters, impracticable to market or to enforce contracts for sale of the
Notes or other debt securities, (iii) trading in any securities of the Company
shall have been suspended by the Commission or a national securities exchange in
the United States, or if trading generally on the New York Stock Exchange shall
have been suspended, or minimum or maximum prices for trading shall have been
fixed, or maximum ranges for prices for securities shall have been required, by
said exchange or by order of the Commission or any other governmental authority,
or if a banking moratorium shall have been declared by either Federal or New
York authorities, (iv) any nationally recognized securities rating agency in the
United States shall have publicly announced that it has (A) placed the Notes or
the Company's long-term debt generally on what is commonly termed a "watch list"
for possible downgrading or (B) downgraded the Notes or the Company's long-term
debt generally, or (v) the Company shall have failed to furnish or cause to be
furnished the certificates, opinions or letters referred to in Section 6 hereof.
 
     (b) If this Agreement is terminated pursuant to this Section, such
termination shall be without liability of any party to any other party except as
provided in Section 5.
 
SECTION 11.  Default by One or More of the Underwriters.
 
     If one or more of the Underwriters shall fail at Closing Time to purchase
the Notes which it or they are obligated to purchase under this Agreement (the
"Defaulted Notes"), the non-defaulting Underwriters shall have the right, within
24 hours thereafter, to make arrangements for one or more of such non-defaulting
Underwriters, or any other underwriters, to purchase all, but not less than all,
of the Defaulted Notes in such
                                       14
   15
 
amounts as may be agreed upon and upon the terms herein set forth; if, however,
such non-defaulting Underwriters shall not have completed such arrangements
within such 24-hour period, then:
 
          (a) if the aggregate principal amount of Defaulted Notes does not
     exceed 10% of the aggregate principal amount of the Notes, the
     non-defaulting Underwriters shall be obligated to purchase the full amount
     thereof in the proportions that their respective underwriting obligations
     hereunder bear to the underwriting obligations of all non-defaulting
     Underwriters, or
 
          (b) if the aggregate principal amount of Defaulted Notes exceeds 10%
     of the aggregate principal amount of the Notes, this Agreement shall
     terminate without liability on the part of any non-defaulting Underwriter.
 
     No action pursuant to this Section shall relieve any defaulting Underwriter
from liability in respect of its default.
 
     In the event of any such default which does not result in a termination of
this Agreement, either the non-defaulting Underwriters or the Company shall have
the right to postpone the Closing Time for a period not exceeding seven days in
order to effect any required changes in the Registration Statement or Prospectus
or in any other documents or arrangements.
 
SECTION 12.  Notices.
 
     All notices and other communications hereunder shall be in writing and
shall be deemed to have been duly given if mailed or transmitted by any standard

Underwriters and the Company and their respective successors. Nothing expressed
or mentioned in this Agreement is intended or shall be construed to give any
person, firm or corporation, other than the parties hereto and their respective

hereto and their respective successors and said controlling persons and officers

shall be governed by and construed in accordance with the laws of the State of
New York applicable to agreements made and to be performed in such State.

        Authorized Signatory



   2



        OCCIDENTAL PETROLEUM CORPORATION, a corporation duly organized and
existing under the laws of the State of Delaware (herein referred to as the
"Company"), for value received, hereby promises to pay to CEDE & CO., or
registered assigns, the Principal Amount specified above on the Maturity Date
specified above (unless and to the extent earlier redeemed or repaid prior to
such Maturity Date) and to pay interest thereon from April 1, 1998 or from the
most recent Interest Payment Date to which interest has been paid or duly
provided for, semiannually in arrears on April 1 and October 1, in each year,
commencing with the first Interest Payment Date next succeeding the Original
Issue Date, at the rate per annum specified above, until the principal hereof is
paid or made available for payment. Interest payments for this Note will include
interest accrued to but excluding each Interest Payment Date. The interest so
payable, and punctually paid or duly provided for, on any Interest Payment Date
will, as provided in the Indenture (as defined below), be paid to the Person in
whose name this Note (or one or more Predecessor Securities) is registered at
the close of business on the Regular Record Date, which shall be the March 15 or
September 15 (whether or not a Business Day), as the case may be, next preceding
such Interest Payment Date. If any Interest Payment Date or Maturity with
respect to this Note falls on a day that is not a Business Day, the payment due
on such Interest Payment Date or at Maturity will be made on the following day
that is a Business Day as if it were made on the date such payment was due and
no interest shall accrue on the amount so payable for the period from and after
such Interest Payment Date or Maturity, as the case may be. Except as otherwise
provided in the Indenture, any interest not punctually paid or duly provided for
on any Interest Payment Date (herein called "Defaulted Interest") will forthwith
cease to be payable to the Holder on the Regular Record Date with respect to
such Interest Payment Date by virtue of having been such Holder and may either
(1) be paid to the Person in whose name this Note (or one or more Predecessor
Securities) is registered at the close of business on a Special Record Date for
the payment of such Defaulted Interest to be fixed by the Trustee (as defined
below), notice of which shall be given to Holders of Notes not less than 10 days
prior to such Special Record Date, or (2) be paid at any time in any other
lawful manner not inconsistent with the requirements of any securities exchange
on which the Notes may be listed, and upon such notice as may be required by
such exchange, all as more fully provided in the Indenture. Payment of the
principal of and interest, if any, on this Note will be made at the Corporate
Trust Office of the Trustee or at the office or agency of the Trustee maintained
for that purpose in the Borough of Manhattan, The City of New York, and at any
other office or agency maintained by the Company for such purpose, in such coin
or currency of the United States of America as at the time of payment is legal
tender for payment of public and private debts; provided, however, that at the
option of the Company, payment of interest may be made by check mailed to the
address of the Person entitled thereto as such address shall appear in the
Security Register and provided, further, that the Holder of this Note shall be
entitled to receive payments of principal of and interest, if any, on this Note
by wire transfer of immediately available funds if appropriate wire transfer
instructions have been received in writing by the Trustee not less than l5 days
prior to the applicable payment date.

        Reference is hereby made to the further provisions of this Note set
forth below, which further provisions shall for all purposes have the same
effect as if set forth at this place.

        Unless the certificate of authentication hereon has been executed by the
Trustee or its duly appointed co-authenticating agent by manual signature, this
Note shall not be entitled to any benefit under the Indenture or be valid or
obligatory for any purpose.

        This Note is one of a duly authorized issue of securities (herein called
the "Securities") of the Company (which term includes any successor corporation
under the Indenture hereinafter referred to)



                                       2

issued and to be issued pursuant to such Indenture. This Security is one of a
Series designated by the Company as its 6.50% Senior Notes due April 1, 2005
(the "Notes"). The Indenture does not limit the aggregate principal amount of
the Notes or the Securities.

        The Company issued this Note pursuant to an Indenture, dated as of April
1, 1998 (herein called the "Indenture" which term, for the purpose of this Note,
shall include the Officers' Certificate dated April 6, 1998, delivered pursuant
to Sections 201 and 301 of the Indenture), between the Company and The Bank of
New York, as trustee (herein called the "Trustee," which term includes any
successor trustee under the Indenture), to which Indenture and all indentures
supplemental thereto reference is hereby made for a statement of the respective
rights, limitations of rights, duties and immunities thereunder of the Company,
the Trustee and Holders of the Notes and of the terms upon which the Notes are,
and are to be, authenticated and delivered.

        The Notes are issuable as Registered Securities, without coupons, in
denominations of $1,000 and any amount in excess thereof which is an integral
multiple of $1,000. As provided in the Indenture and subject to certain
limitations therein set forth, Notes are exchangeable for a like aggregate
principal amount of Notes of like tenor of any authorized denomination, as
requested by the Holder surrendering the same, upon surrender of the Note or
Notes to be exchanged at any office or agency described below where Notes may be
presented for registration of transfer.

        The Notes are redeemable, in whole or in part, at the option of the
Company at any time at a redemption price equal to the greater of (i) 100% of
the principal amount of the Notes and (ii) an amount (determined by the
Quotation Agent (as defined herein)) equal to the sum of the present values of
the remaining scheduled payments of principal and interest on the Notes (not
including any portion of such payments of interest accrued as of the date of the
redemption) discounted to the date of redemption on a semiannual basis (assuming
a 360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate
(as defined herein) plus 15 basis points plus accrued interest thereon to the
date of redemption.

        "Adjusted Treasury Rate" means, with respect to any redemption date, the
rate per annum equal to the semiannual equivalent yield to maturity of the
Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue
(expressed as a percentage of its principal amount) equal to the Comparable
Treasury Price for such redemption date.

        "Comparable Treasury Issue" means the United States Treasury security
selected by the Quotation Agent as having a maturity comparable to the remaining
term of the Notes to be redeemed that would be utilized, at the time of
selection and in accordance with customary financial practice, in pricing new
issues of corporate debt securities of comparable maturity to the remaining term
of the Notes.

        "Comparable Treasury Price" means, with respect to any redemption date,
(i) the average of the Reference Treasury Dealer Quotations for such redemption
date, after excluding the highest and lowest such Reference Treasury Dealer
Quotations, or (ii) if the Trustee obtains fewer than three such Reference
Treasury Dealer Quotations, the average of such Quotations, such average in any
case to be determined by the Quotation Agent, or (iii) if only one Reference
Treasury Dealer Quotation is received, such Quotation.



                                       3

   4

        "Quotation Agent" means the Reference Treasury Dealer appointed by the
Company.

        "Reference Treasury Dealer" means (i) J.P. Morgan Securities Inc.,
Merrill Lynch, Pierce, Fenner & Smith Incorporated, BancAmerica Robertson
Stephens, Chase Securities Inc. and Morgan Stanley & Co. Incorporated and their
respective successors; provided, however, that if any of the foregoing shall
cease to be a primary U.S. Government securities dealer in New York City (a
"Primary Treasury Dealer"), the Company shall substitute therefor another
Primary Treasury Dealer, and (ii) any other Primary Treasury Dealer(s) selected
by the Company.

        "Reference Treasury Dealer Quotations" means, with respect to each
Reference Treasury Dealer and any redemption date, the average, as determined by
the Quotation Agent, of the bid and asked prices for the Comparable Treasury
Issue (expressed in each case as a percentage of its principal amount) quoted in
writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m. on the
third Business Day in the City of New York preceding such redemption date.

        Notice of any redemption will be mailed at least 30 days but not more
than 60 days before the redemption date to each Holder of the Notes to be
redeemed. Unless the Company defaults in payment of the redemption price, on and
after the redemption date, interest will cease to accrue on the Notes or
portions thereof called for redemption. If less than all of the Notes are to be
redeemed, the Notes (or portions thereof) to be redeemed shall be selected by
the Trustee by such method as the Trustee shall deem fair and appropriate.

        Notwithstanding the foregoing, installments of interest whose Stated
Maturity is prior to the Redemption Date of any Note will be payable to the
Holder of such Note, or one or more Predecessor Securities, of record at the
close of business on the relevant Regular Record Date referred to above, all as
provided in the Indenture.

        All notices of redemption shall state the Redemption Date, the
Redemption Price, if fewer than all the Outstanding Notes are to be redeemed,
the identification (and, in the case of partial redemption, the principal
amounts) of the particular Notes to be redeemed, that on the Redemption Date the
Redemption Price will become due and payable upon each Note, or portion thereof,
to be redeemed, that interest on each Note, or portion thereof, called for
redemption will cease to accrue on the Redemption Date and the place or places
where Notes may be surrendered for redemption. If fewer than all of the Notes
are to be redeemed at any time, selection of such Notes for redemption will be
made by the Trustee by such method as the Trustee shall deem fair and
appropriate.

        In the event of redemption of this Note in part only, a new Note or
Notes of like tenor for the unredeemed portion hereof will be issued in
authorized denominations in the name of the Holder hereof upon the cancellation
hereof.

        For all purposes of this Note and the Indenture, unless the context
otherwise requires, all provisions relating to the redemption by the Company of
this Note shall relate, in the case that this Note is redeemed or to be redeemed
by the Company only in part to that portion of the principal amount of this Note
that has been or is to be redeemed.

        If an Event of Default with respect to Notes shall occur and be
continuing, the principal of the Notes may be declared due and payable in the
manner and with the effect provided in the Indenture.

        The Indenture permits, in certain circumstances therein specified, the
amendment thereof without the consent of the Holders of the Securities. The
Indenture also permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations under the
Indenture of the Company and the rights of Holders of the Securities of each
series to be affected under the Indenture at any time by the Company and the
Trustee with the consent of the Holders of a majority in aggregate principal
amount of the Securities at the time Outstanding of each series to be affected.
The Indenture also contains provisions permitting the Holders of a majority in
aggregate principal amount of the Securities of each series at the time
Outstanding, on behalf of the Holders of all the Securities of such series, to
waive compliance by the Company with certain provisions of the Indenture and
certain past defaults under the Indenture and their consequences. Any such
consent or waiver by the Holder of this Note shall be conclusive and binding
upon such Holder and upon all future Holders of this Note and of any Note issued
upon the registration of transfer hereof or in exchange herefor or in lieu
hereof, whether or not notation of such consent or waiver is made upon this
Note.

        No reference herein to the Indenture and no provision of this Note or,
subject to the provisions for satisfaction and discharge in Article Four of the
Indenture shall alter or impair the obligation of the Company, which is absolute
and unconditional, to pay the principal of and interest on this Note at the
times, place and rate, and in the coin or currency, herein prescribed.

        The Indenture permits the Company, by irrevocably depositing, in amounts
and maturities sufficient to pay and discharge at the Stated Maturity or
Redemption Date, as the case may be, the entire indebtedness on all Outstanding
Notes, cash or U.S. Government Obligations with the Trustee in trust solely for
the benefit of the Holders of all Outstanding Notes, to defease the Indenture
with respect to such Notes, and upon such deposit the Company shall be deemed to
have paid and discharged its entire indebtedness on such Notes. Thereafter,
Holders would be able to look only to such trust fund for payment of principal
and interest at the Stated Maturity or Redemption Date, as the case may be.

        As provided in the Indenture and subject to certain limitations therein
set forth, the transfer of Notes is registrable in the Security Register, upon
surrender of a Note for registration of transfer at the Corporate Trust Office
of the Trustee or at the office or agency of the Trustee in the Borough of
Manhattan, The City of New York, or at such other offices or agencies as the
Company may designate, duly endorsed by, or accompanied by a written instrument
of transfer in form satisfactory to the Company and the Security Registrar duly
executed by, the Holder hereof or his attorney duly authorized in writing, and
thereupon one or more new Notes of like tenor, of authorized denominations and
for the same aggregate principal amount, will be issued to the designated
transferee or transferees.

        No service charge shall be made by the Company, the Trustee or the
Security Registrar for any such registration of transfer or exchange, but the
Company may require payment of a sum sufficient to cover any tax or other
governmental charge payable in connection therewith (other than exchanges
pursuant to Sections 304, 906 or 1107 of the Indenture, not involving any
transfer).

        Prior to due presentment of this Note for registration of transfer, the
Company, the Trustee and any agent of the Company or the Trustee may treat the
Person in whose name this Note is registered as

        OCCIDENTAL PETROLEUM CORPORATION, a corporation duly organized and
existing under the laws of the State of Delaware (herein referred to as the
"Company"), for value received, hereby promises to pay to CEDE & CO., or
registered assigns, the Principal Amount specified above on the Maturity Date
specified above (unless and to the extent earlier redeemed or repaid prior to
such Maturity Date) and to pay interest thereon from April 1, 1998 or from the
most recent Interest Payment Date to which interest has been paid or duly
provided for, semiannually in arrears on April 1 and October 1, in each year,
commencing with the first Interest Payment Date next succeeding the Original
Issue Date, at the rate per annum specified above, until the principal hereof is
paid or made available for payment. Interest payments for this Note will include
interest accrued to but excluding each Interest Payment Date. The interest so
payable, and punctually paid or duly provided for, on any Interest Payment Date
will, as provided in the Indenture (as defined below), be paid to the Person in
whose name this Note (or one or more Predecessor Securities) is registered at
the close of business on the Regular Record Date, which shall be the March 15 or
September 15 (whether or not a Business Day), as the case may be, next preceding
such Interest Payment Date. If any Interest Payment Date or Maturity with
respect to this Note falls on a day that is not a Business Day, the payment due
on such Interest Payment Date or at Maturity will be made on the following day
that is a Business Day as if it were made on the date such payment was due and
no interest shall accrue on the amount so payable for the period from and after
such Interest Payment Date or Maturity, as the case may be. Except as otherwise
provided in the Indenture, any interest not punctually paid or duly provided for
on any Interest Payment Date (herein called "Defaulted Interest") will forthwith
cease to be payable to the Holder on the Regular Record Date with respect to
such Interest Payment Date by virtue of having been such Holder and may either
(1) be paid to the Person in whose name this Note (or one or more Predecessor
Securities) is registered at the close of business on a Special Record Date for
the payment of such Defaulted Interest to be fixed by the Trustee (as defined
below), notice of which shall be given to Holders of Notes not less than 10 days
prior to such Special Record Date, or (2) be paid at any time in any other
lawful manner not inconsistent with the requirements of any securities exchange
on which the Notes may be listed, and upon such notice as may be required by
such exchange, all as more fully provided in the Indenture. Payment of the
principal of and interest, if any, on this Note will be made at the Corporate
Trust Office of the Trustee or at the office or agency of the Trustee maintained
for that purpose in the Borough of Manhattan, The City of New York, and at any
other office or agency maintained by the Company for such purpose, in such coin
or currency of the United States of America as at the time of payment is legal
tender for payment of public and private debts; provided, however, that at the
option of the Company, payment of interest may be made by check mailed to the
address of the Person entitled thereto as such address shall appear in the
Security Register and provided, further, that the Holder of this Note shall be
entitled to receive payments of principal of and interest, if any, on this Note
by wire transfer of immediately available funds if appropriate wire transfer
instructions have been received in writing by the Trustee not less than l5 days
prior to the applicable payment date.

        Reference is hereby made to the further provisions of this Note set
forth below, which further provisions shall for all purposes have the same
effect as if set forth at this place.

        Unless the certificate of authentication hereon has been executed by the
Trustee or its duly appointed co-authenticating agent by manual signature, this
Note shall not be entitled to any benefit under the Indenture or be valid or
obligatory for any purpose.

        This Note is one of a duly authorized issue of securities (herein called
the "Securities") of the Company (which term includes any successor corporation
under the Indenture hereinafter referred to)



                                       2

issued and to be issued pursuant to such Indenture. This Security is one of a
Series designated by the Company as its 7.20% Senior Notes due April 1, 2028
(the "Notes"). The Indenture does not limit the aggregate principal amount of
the Notes or the Securities.

        The Company issued this Note pursuant to an Indenture, dated as of April
1, 1998 (herein called the "Indenture" which term, for the purpose of this Note,
shall include the Officers' Certificate dated April 6, 1998, delivered pursuant
to Sections 201 and 301 of the Indenture), between the Company and The Bank of
New York, as trustee (herein called the "Trustee," which term includes any
successor trustee under the Indenture), to which Indenture and all indentures
supplemental thereto reference is hereby made for a statement of the respective
rights, limitations of rights, duties and immunities thereunder of the Company,
the Trustee and Holders of the Notes and of the terms upon which the Notes are,
and are to be, authenticated and delivered.

        The Notes are issuable as Registered Securities, without coupons, in
denominations of $1,000 and any amount in excess thereof which is an integral
multiple of $1,000. As provided in the Indenture and subject to certain
limitations therein set forth, Notes are exchangeable for a like aggregate
principal amount of Notes of like tenor of any authorized denomination, as
requested by the Holder surrendering the same, upon surrender of the Note or
Notes to be exchanged at any office or agency described below where Notes may be
presented for registration of transfer.

        The Notes are redeemable, in whole or in part, at the option of the
Company at any time at a redemption price equal to the greater of (i) 100% of
the principal amount of the Notes and (ii) an amount (determined by the
Quotation Agent (as defined herein)) equal to the sum of the present values of
the remaining scheduled payments of principal and interest on the Notes (not
including any portion of such payments of interest accrued as of the date of the
redemption) discounted to the date of redemption on a semiannual basis (assuming
a 360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate
(as defined herein) plus 20 basis points plus accrued interest thereon to the
date of redemption.

        "Adjusted Treasury Rate" means, with respect to any redemption date, the
rate per annum equal to the semiannual equivalent yield to maturity of the
Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue
(expressed as a percentage of its principal amount) equal to the Comparable
Treasury Price for such redemption date.

        "Comparable Treasury Issue" means the United States Treasury security
selected by the Quotation Agent as having a maturity comparable to the remaining
term of the Notes to be redeemed that would be utilized, at the time of
selection and in accordance with customary financial practice, in pricing new
issues of corporate debt securities of comparable maturity to the remaining term
of the Notes.

        "Comparable Treasury Price" means, with respect to any redemption date,
(i) the average of the Reference Treasury Dealer Quotations for such redemption
date, after excluding the highest and lowest such Reference Treasury Dealer
Quotations, or (ii) if the Trustee obtains fewer than three such Reference
Treasury Dealer Quotations, the average of such Quotations, such average in any
case to be determined by the Quotation Agent, or (iii) if only one Reference
Treasury Dealer Quotation is received, such Quotation.



                                       3

   4

        "Quotation Agent" means the Reference Treasury Dealer appointed by the
Company.

        "Reference Treasury Dealer" means (i) J.P. Morgan Securities Inc.,
Merrill Lynch, Pierce, Fenner & Smith Incorporated, BancAmerica Robertson
Stephens, Chase Securities Inc. and Morgan Stanley & Co. Incorporated and their
respective successors; provided, however, that if any of the foregoing shall
cease to be a primary U.S. Government securities dealer in New York City (a
"Primary Treasury Dealer"), the Company shall substitute therefor another
Primary Treasury Dealer, and (ii) any other Primary Treasury Dealer(s) selected
by the Company.

        "Reference Treasury Dealer Quotations" means, with respect to each
Reference Treasury Dealer and any redemption date, the average, as determined by
the Quotation Agent, of the bid and asked prices for the Comparable Treasury
Issue (expressed in each case as a percentage of its principal amount) quoted in
writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m. on the
third Business Day in the City of New York preceding such redemption date.

        Notice of any redemption will be mailed at least 30 days but not more
than 60 days before the redemption date to each Holder of the Notes to be
redeemed. Unless the Company defaults in payment of the redemption price, on and
after the redemption date, interest will cease to accrue on the Notes or
portions thereof called for redemption. If less than all of the Notes are to be
redeemed, the Notes (or portions thereof) to be redeemed shall be selected by
the Trustee by such method as the Trustee shall deem fair and appropriate.

        Notwithstanding the foregoing, installments of interest whose Stated
Maturity is prior to the Redemption Date of any Note will be payable to the
Holder of such Note, or one or more Predecessor Securities, of record at the
close of business on the relevant Regular Record Date referred to above, all as
provided in the Indenture.

        All notices of redemption shall state the Redemption Date, the
Redemption Price, if fewer than all the Outstanding Notes are to be redeemed,
the identification (and, in the case of partial redemption, the principal
amounts) of the particular Notes to be redeemed, that on the Redemption Date the
Redemption Price will become due and payable upon each Note, or portion thereof,
to be redeemed, that interest on each Note, or portion thereof, called for
redemption will cease to accrue on the Redemption Date and the place or places
where Notes may be surrendered for redemption. If fewer than all of the Notes
are to be redeemed at any time, selection of such Notes for redemption will be
made by the Trustee by such method as the Trustee shall deem fair and
appropriate.

        In the event of redemption of this Note in part only, a new Note or
Notes of like tenor for the unredeemed portion hereof will be issued in
authorized denominations in the name of the Holder hereof upon the cancellation
hereof.

        For all purposes of this Note and the Indenture, unless the context
otherwise requires, all provisions relating to the redemption by the Company of
this Note shall relate, in the case that this Note is redeemed or to be redeemed
by the Company only in part to that portion of the principal amount of this Note
that has been or is to be redeemed.



                                       4

   5

        If an Event of Default with respect to Notes shall occur and be
continuing, the principal of the Notes may be declared due and payable in the
manner and with the effect provided in the Indenture.

        The Indenture permits, in certain circumstances therein specified, the

Indenture also permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations under the

The Indenture also contains provisions permitting the Holders of a majority in

Outstanding, on behalf of the Holders of all the Securities of such series, to
waive compliance by the Company with certain provisions of the Indenture and
certain past defaults under the Indenture and their consequences. Any such
consent or waiver by the Holder of this Note shall be conclusive and binding
upon such Holder and upon all future Holders of this Note and of any Note issued
upon the registration of transfer hereof or in exchange herefor or in lieu
hereof, whether or not notation of such consent or waiver is made upon this
Note.

        No reference herein to the Indenture and no provision of this Note or,
subject to the provisions for satisfaction and discharge in Article Four of the
Indenture shall alter or impair the obligation of the Company, which is absolute
and unconditional, to pay the principal of and interest on this Note at the
times, place and rate, and in the coin or currency, herein prescribed.

        The Indenture permits the Company, by irrevocably depositing, in amounts

of transfer in form satisfactory to the Company and the Security Registrar duly
executed by, the Holder hereof or his attorney duly authorized in writing, and
thereupon one or more new Notes of like tenor, of authorized denominations and
for the same aggregate principal amount, will be issued to the designated
transferee or transferees.

        No service charge shall be made by the Company, the Trustee or the
Security Registrar for any such registration of transfer or exchange, but the
Company may require payment of a sum sufficient to cover any tax or other
governmental charge payable in connection therewith (other than exchanges
pursuant to Sections 304, 906 or 1107 of the Indenture, not involving any

        Prior to due presentment of this Note for registration of transfer, the
Company, the Trustee and any agent of the Company or the Trustee may treat the

        OCCIDENTAL PETROLEUM CORPORATION, a corporation duly organized and
existing under the laws of the State of Delaware (herein referred to as the
"Company"), for value received, hereby promises to pay to CEDE & CO., or
registered assigns, the Principal Amount specified above on the Maturity Date
specified above (unless and to the extent earlier redeemed or repaid prior to
such Maturity Date) and to pay interest thereon from April 1, 1998 or from the
most recent Interest Payment Date to which interest has been paid or duly
provided for, semiannually in arrears on April 1 and October 1, in each year,
commencing with the first Interest Payment Date next succeeding the Original
Issue Date, to the Remarketing Date specified above at the Interest Rate to
Remarketing Date specified above, and thereafter, subject to the terms and
conditions set forth herein, at the Interest Rate determined by the Remarketing
Dealer (as defined below) in accordance with the procedures set forth below
("Interest Rate to Maturity"), until the principal hereof is paid or made
available for payment. Interest payments for this Note will include interest
accrued to but excluding each Interest Payment Date. The interest so payable,
and punctually paid or duly provided for, on any Interest Payment Date will, as
provided in the Indenture (as defined below), be paid to the Person in whose
name this Note (or one or more Predecessor Securities) is registered at the
close of business on the Regular Record Date, which shall be the March 15 or
September 15 (whether or not a Business Day), as the case may be, next preceding
such Interest Payment Date. If any Interest Payment Date or Maturity with
respect to this Note falls on a day that is not a Business Day, the payment due
on such Interest Payment Date or at Maturity will be made on the following day
that is a Business Day as if it were made on the date such payment was due and
no interest shall accrue on the amount so payable for the period from and after
such Interest Payment Date or Maturity, as the case may be. Except as otherwise
provided in the Indenture, any interest not punctually paid or duly provided for
on any Interest Payment Date (herein called "Defaulted Interest") will forthwith
cease to be payable to the Holder on the Regular Record Date with respect to
such Interest Payment Date by virtue of having been such Holder and may either
(1) be paid to the Person in whose name this Note (or one or more Predecessor
Securities) is registered at the close of business on a Special Record Date for
the payment of such Defaulted Interest to be fixed by the Trustee (as defined
below), notice of which shall be given to Holders of Notes not less than 10 days
prior to such Special Record Date, or (2) be paid at any time in any other
lawful manner not inconsistent with the requirements of any securities exchange
on which the Notes may be listed, and upon such notice as may be required by
such exchange, all as more fully provided in the Indenture. Payment of the
principal of and interest, if any, on this Note will be made at the Corporate
Trust Office of the Trustee or at the office or agency of the Trustee maintained
for that purpose in the Borough of Manhattan, The City of New York, and at any
other office or agency maintained by the Company for such purpose, in such coin
or currency of the United States of America as at the time of payment is legal
tender for payment of public and private debts; provided, however, that at the
option of the Company, payment of interest may be made by check mailed to the
address of the Person entitled thereto as such address shall appear in the
Security Register and provided, further, that the Holder of this Note shall be
entitled to receive payments of principal of and interest, if any, on this Note
by wire transfer of immediately available funds if appropriate wire transfer
instructions have been received in writing by the Trustee not less than l5 days
prior to the applicable payment date.

        Reference is hereby made to the further provisions of this Note set
forth below, which further provisions shall for all purposes have the same
effect as if set forth at this place.

        Unless the certificate of authentication hereon has been executed by the
Trustee or its duly appointed co-authenticating agent by manual signature, this
Note shall not be entitled to any benefit under the Indenture or be valid or
obligatory for any purpose.

        This Note is one of a duly authorized issue of securities (herein called
the "Securities") of the Company (which term include any successor corporation
under the Indenture hereinafter referred to) issued and to be issued pursuant to
such Indenture. This Security is one of a Series designated by the Company as
its 6.40% Senior Notes due April 1, 2013, Mandatorily Tendered on April 1, 2003
(the "Notes"). The Indenture does not limit the aggregate principal amount of
the Notes or the Securities.

        The Company issued this Note pursuant to an Indenture, dated as of April
1, 1998 (herein called the "Indenture" which term, for the purpose of this Note,
shall include the Officers' Certificate dated April 6, 1998, delivered pursuant
to Sections 201 and 301 of the Indenture), between the Company and The Bank of
New York, as trustee (herein called the "Trustee," which term includes any
successor trustee under the Indenture), to which Indenture and all indentures
supplemental thereto reference is hereby made for a statement of the respective
rights, limitations of rights, duties and immunities thereunder of the Company,
the Trustee and Holders of the Notes and of the terms upon which the Notes are,
and are to be, authenticated and delivered.

        The Notes are issuable as Registered Securities, without coupons, in
denominations of $1,000 and any amount in excess thereof which is an integral
multiple of $1,000. As provided in the Indenture and subject to certain
limitations therein set forth, Notes are exchangeable for a like aggregate
principal amount of Notes of like tenor of any authorized denomination, as
requested by the Holder surrendering the same, upon surrender of the Note or
Notes to be exchanged at any office or agency described below where Notes may be
presented for registration of transfer.

        Certain provisions relating to the remarketing of the Notes set forth
below are contained in a Remarketing Agreement (the "Remarketing Agreement")
between the Company and Merrill Lynch, Pierce, Fenner & Smith Incorporated, as
Remarketing Dealer (the "Remarketing Dealer").

        Provided that on a Business Day not later than five Business Days prior
to the Remarketing Date the Remarketing Dealer notifies the Company and the
Trustee of its election to purchase the Notes on the Remarketing Date for
remarketing (the "Notification Date"), the Notes shall be subject to mandatory
tender to the Remarketing Dealer, and the Remarketing Dealer shall be obligated
to purchase the Notes, for remarketing on the Remarketing Date, subject in each
case to the conditions described herein and set forth in the Remarketing
Agreement. The purchase price for the tendered Notes shall equal 100% of the
principal amount thereof. From and after the Remarking Date, the Note shall bear
interest at the Interest Rate to Maturity as specified herein. If the
Remarketing Dealer elects to remarket the Notes, the obligation of the
Remarketing Dealer to purchase the Notes on the Remarketing Date is subject to
the conditions specified in the Remarketing Agreement. If the Remarketing Dealer
purchases notes on the Remarketing Date, it must purchase all of the Notes. If
for any reason the Remarketing Dealer does not purchase all of the Notes on the
Remarketing Date, the Company shall be required to repurchase from the
registered holders thereof, and the registered holders will be required to sell
to the Company, all the Notes at a price equal to the principal amount thereof
plus all accrued and unpaid interest, if any, on the Notes to the Remarketing
Date as specified herein.

        Subject to the Remarketing Dealer's election to remarket the Notes as
specified above and subject further to provisions herein and the Remarketing
Agreement, the Interest Rate to Maturity shall be determined by the Remarketing
Dealer by 3:30 p.m., New York City time, on the third Business Day immediately
preceding the Remarketing Date (the "Determination Date") to the nearest one
hundred-



                                       3

   4

thousandth (0.00001) of one percent per annum, and will be equal to the sum of
5.666% (the "Base Rate") plus the Applicable Spread (as defined below), which
will be based on the Dollar Price (as defined below) of the Notes.

        The "Applicable Spread" will be the lowest bid, expressed as a spread
(in the form of a percentage or in basis points) above the Base Rate, obtained
by the Remarketing Dealer on the Determination Date from the bids quoted by five
Reference Corporate Dealers (as defined below) for the purchase by such
Reference Corporate Dealer of the full aggregate principal amount of the Notes
at the Dollar Price, assuming (i) an issue date equal to the Remarketing Date,
with settlement on such date without accrued interest, (ii) the Maturity Date
specified above, and (iii) a stated annual interest rate, payable semiannually
on each Interest Payment Date for the Notes, equal to the Base Rate plus the
spread bid by the applicable Reference Corporate Dealer. If fewer than five
Reference Corporate Dealers bid as described above, then the Applicable Spread
shall be the lowest of such bids obtained as described above. Each such bid
shall be the price, expressed as a spread above the Base Rate based on the
assumptions set forth above, at which the applicable Reference Corporate Dealer
irrevocably commits to purchase the entire principal amount of the Notes for
settlement on the Remarketing Date. Subject to the purchase of the Notes by the
Remarketing Dealer on the Remarketing Date, the Remarketing Dealer will sell the
Notes to the Reference Corporate Dealer that submits the lowest bid (if other
than the Remarketing Dealer itself), such sale to be settled by payment on the
Remarketing Date in immediately available funds; provided, that if such
Reference Corporate Dealer notifies the Remarketing Dealer that it will not make
such purchase or for any reason fails to make such payment to the Remarketing
Dealer by 1:00 p.m., New York City time, on the Remarketing Date, the
Remarketing Dealer shall not longer be obligated to sell the Notes to such
Reference Corporate Dealer. If the Applicable Spread is bid by more than one
Reference Corporate Dealer, the Remarketing Dealer shall select, from among such
Reference Corporate Dealers, the Reference Corporate Dealer (other than the
Remarketing Dealer) to which it will sell the Notes as set forth in the
immediately preceding sentence. The Interest Rate to Maturity announced by the
Remarketing Dealer, absent manifest error, shall be binding and conclusive upon
the Beneficial Owners and Holders of the Notes, the Company and the Trustee.

        "Beneficial Owner" shall mean each person who acquires an interest in
the Note which is reflected on the records of DTC through its participants.

        "Dollar Price" means, with respect to the Notes, the present value
determined by the Remarketing Dealer, as of the Remarketing Date, of the
Remaining Scheduled Payments (as defined below) discounted to the Remarketing
Date, on a semiannual basis (assuming a 360-day year consisting of twelve 30-day
months), at the Treasury Rate (as defined below).

        "Reference Corporate Dealers" mean leading dealers of publicly traded
debt securities of the Company in The City of New York (which, unless otherwise
specified by the Remarketing Dealer, shall include the Remarketing Dealer or one
of its affiliates) selected by the Company, after consultation with the
Remarketing Dealer and notified to the Remarketing Dealer, not later than one
Business Day prior to the Determination Date; provided, that if the Company does
not so notify the Remarketing Dealer by the close of business on the Business
Day prior to the Determination Date, then such Reference Corporate Dealers shall
be selected by the Remarketing Dealer.

per annum equal to the semiannual equivalent yield to maturity or interpolated

(as defined below) for such Remarketing Date.

        "Comparable Treasury Issues" means the current on-the-run (as such term
is used by dealers in the United States Treasury securities market) ten-year
United States Treasury security as set forth at 11:00 a.m., New York City time,
on the Determination Date on "Telerate Page 500" (as defined below) (or such
other page as may replace Telerate Page 500); provided, that, if ten-year United
States Treasury securities shall not have been issued within the twelve-month
period preceding the Remarketing Date, "Comparable Treasury Issues" shall mean
the United States Treasury security or securities selected by the Remarketing
Dealer as having an actual or interpolated maturity or maturities comparable to
the term remaining to the Maturity Date of the Notes being remarketed.

        "Comparable Treasury Price" means, with respect to the Remarketing Date,
(a) the offer prices for the comparable Treasury Issues (expressed in each case
as a percentage of its principal amount) on the Determination Date, as set forth
on "Telerate Page 500" (or such other page as may replace Telerate Page 500), or
(b) if such page (or any successor page) is not displayed or does not contain
such offer prices on the Determination Date, (i) the average of the Reference
Treasury Dealer Quotations for such Remarketing Date, after excluding the
highest and lowest of such Reference Treasury Dealer Quotations, or (ii) if the
Remarketing Dealer obtains fewer than four such Reference Treasury Dealer
Quotations, the average of all such Reference Treasury Dealer Quotations.
"Telerate Page 500" means the display designated as "Telerate Page 500" on Dow

        "Reference Treasury Dealer Quotations" means, with respect to each
Reference Treasury Dealer and the Remarketing Date, the offer prices for the
Comparable Treasury Issues (expressed in each case as a percentage of its
principal amount) quoted to the Remarketing Dealer by such Reference Treasury

        "Reference Treasury Dealer" means, with respect to the Remarketing Date,
each of BancAmerica Robertson Stephens, Chase Securities Inc., Merrill Lynch,
Pierce, Fenner & Smith Incorporated, J.P. Morgan Securities Inc. and Morgan
Stanley & Co. Incorporated (or their respective affiliates which are primary
U.S. Government securities dealers) and their respective successors; provided,
however, that if any of the foregoing or their affiliates shall cease to be a
primary U.S. Government securities dealer in The City of New York ( a "Primary
Treasury Dealer"), the Remarketing Dealer shall substitute therefore another
Primary Treasury Dealer.

        "Remaining Scheduled Payments" means, with respect to the Notes, the
remaining scheduled payments of the principal thereof and interest thereon,
calculated at the Base Rate only, that would be due after the Remarketing Date
to and including the Maturity Date, as determined by the Remarketing Dealer.

        Provided the Remarketing Dealer has previously notified the Company and
the Trustee on the Notification Date of its intention to purchase all Notes on
the Remarketing Date and subject to the



                                       5

Company's right to redeem the Notes from the Remarketing Dealer on the
Remarketing Date as set forth below, the Remarketing Dealer will notify the
Company, the Trustee and DTC by telephone, confirmed in writing (which may
include facsimile or other electronic transmission), by 4:00 p.m., New York City
time, on the Determination Date, of the Interest Rate to Maturity. All of the
tendered Notes shall be automatically delivered to the account of the Trustee,
by book-entry through DTC pending payment of the purchase price therefor, on the
Remarketing Date.

        In the event that the Notes are remarketed on the Remarketing Date, the
Remarketing Dealer shall make or cause the Trustee to make payment to the DTC
Participant of each Beneficial Owner of Notes, by book-entry through DTC no
later than the close of business on the Remarketing Date against delivery
through DTC of such Beneficial Owner's tendered Notes, of 100% of the principal
amount of the tendered Notes that have been purchased for remarketing by the
Remarketing Dealer. If the Remarketing Dealer does not purchase all of the Notes
on the Remarketing Date, it shall be the obligation of the Company to make or
cause to be made such payment for the Notes, as provided herein. In any case,
the Company shall make, or cause the Trustee to make, payment of interest in the
normal course on the Notes due on the Remarketing Date in accordance with the
Indenture by book-entry through DTC no later than the close of business on the
Remarketing Date.

        "DTC Participant" shall mean any person that has an account with DTC
through which Beneficial Owners acquire, directly or indirectly, an interest in
the Notes.

        The transactions specified above shall be executed on the Remarketing
Date through DTC in accordance with the procedures of DTC, and the accounts of
the respective DTC Participants will be debited and credited and the Notes
delivered by book-entry as necessary to effect the purchases and sales thereof.

        The tender and settlement procedures set forth above, including
provisions for payment by purchasers of Notes in the remarketing or for payment
to selling Beneficial Owners of Notes, may be modified to the extent required by
DTC or to the extent required to facilitate the tender and remarketing of Notes
in certificated form, if the book-entry system is no longer available for the
Notes at the time of the remarketing. In addition, the Remarketing Dealer may,
without the consent of holders or Beneficial Owners of the Notes, modify the
tender and settlement procedures specified above in order to facilitate the
tender and settlement process.

        As long as DTC's nominee holds the certificates representing any Notes
in the book-entry system of DTC, no certificates for such Notes will be
delivered by any selling Beneficial Owner to reflect any transfer of such Notes
effected in the remarketing.

        In the event that (i) the Remarketing Dealer for any reason does not
notify the Company of the Interest Rate to Maturity by 4:00 p.m., New York City
time, on the Determination Date, or (ii) prior to the Remarketing Date, the
Remarketing Dealer has resigned and no successor has been appointed on or before
the Determination Date, or (iii) the Remarketing Dealer has terminated the
Remarketing Agreement pursuant to Section 11 thereof at any time after the
Remarketing Dealer elects on the Notification Date to remarket the Notes, or
(iv) the Remarketing Dealer for any reason does not elect to purchase the Notes
for remarketing on the Remarketing Date, or (v) the Remarketing Dealer for any
reason does not purchase all tendered Notes on the Remarketing Date, the Company
shall repurchase all the Notes as a whole on



                                       6

   7

the Remarketing Date at a price equal to 100% of the principal amount of the
Notes plus all accrued and unpaid interest, if any, on the Notes to the
Remarketing Date. In any such case, payment will be made by the Company to the
registered holders of the Notes, by book-entry through DTC no later than the
close of business on the Remarketing Date against delivery through DTC of such
Beneficial Owner's tendered Notes.

        If the Remarketing Dealer elects to remarket the Notes on the
Remarketing Date, then not later than the close of business on the Business Day
immediately preceding the Determination Date, the Company shall notify the
Remarketing Dealer and the Trustee if the Company irrevocably elects to exercise
its right to redeem the Notes, in whole but not in part, from the Remarketing
Dealer on the Remarketing Date at the Optional Redemption Price. If the Company
fails to elect, or elects not to, redeem the Notes pursuant to this paragraph,
the Remarketing Dealer will determine the Interest Rate to Maturity as provided
above.

        The "Optional Redemption Price" shall be the greater of (i) 100% of the
principal amount of the Notes and (ii) the sum of the present values of the
Remaining Scheduled Payments thereon, as determined by the Remarketing Dealer,
discounted to the Remarketing Date on a semiannual basis (assuming a 360- day
year consisting of twelve 30-day months) at the Treasury Rate, plus in either
case accrued and unpaid interest at a rate of 6.40% per annum from the
Remarketing Date on the principal amount being redeemed to the date of
redemption if payment in respect of such redemption occurs after the Remarketing
Date. If the Company elects to redeem the Notes, it shall pay the redemption
price therefor in same-day funds by wire transfer to an account designated by
the Remarketing Dealer on the Remarketing Date.

        After the Remarketing Date, the Notes are redeemable, in whole or in
part, at the option of the Company at any time at a redemption price equal to
the greater of (i) 100% of the principal amount of the Notes and (ii) an amount
(determined by the Quotation Agent (as defined below)) equal to the sum of the
present values of the remaining scheduled payments of principal and interest on
the Notes (not including any portion of such payments of interest accrued as of
the date of the redemption) discounted to the date of redemption on a semiannual
basis (assuming a 360-day year consisting of twelve 30-day months) at the
Adjusted Treasury Rate (as defined below) plus 15 basis points plus accrued
interest thereon to the date of redemption.

        "Adjusted Treasury Rate" means, with respect to any redemption date, the
rate per annum equal to the semiannual equivalent yield to maturity of the
Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue
(expressed as a percentage of its principal amount) equal to the Comparable
Treasury Price for such redemption date.

        "Comparable Treasury Issue" means the United States Treasury security
selected by the Quotation Agent as having a maturity comparable to the remaining
term of the Notes to be redeemed that would be utilized, at the time of
selection and in accordance with customary financial practice, in pricing new
issues of corporate debt securities of comparable maturity to the remaining term
of the Notes.

        "Comparable Treasury Price" means, with respect to any redemption date,
(i) the average of the Reference Treasury Dealer Quotations for such redemption
date, after excluding the highest and lowest such Reference Treasury Dealer
Quotations, or (ii) if the Trustee obtains fewer than three such Reference
Treasury Dealer Quotations, the average of such Quotations, such average in any
case to be determined



                                       7

   8

by the Quotation Agent, or (iii) if only one Reference Treasury Dealer Quotation
is received, such Quotation.

        "Quotation Agent" means the Reference Treasury Dealer appointed by the
Company.

        "Reference Treasury Dealer" means, with respect to any redemption date
after the Remarketing Date, (i) J.P. Morgan Securities Inc., Merrill Lynch,
Pierce, Fenner & Smith Incorporated, BancAmerica Robertson Stephens, Chase
Securities Inc. and Morgan Stanley & Co. Incorporated and their respective
successors; provided, however, that if any of the foregoing shall cease to be a
primary U.S. Government securities dealer in New York City (a "Primary Treasury
Dealer"), the Company shall substitute therefor another Primary Treasury Dealer,
and (ii) any other Primary Treasury Dealer(s) selected by the Company.

        "Reference Treasury Dealer Quotations" means, with respect to each
Reference Treasury Dealer and any redemption date, the average, as determined by
the Quotation Agent, of the bid and asked prices for the Comparable Treasury
Issue (expressed in each case as a percentage of its principal amount) quoted in
writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m. on the
third Business Day in the City of New York preceding such redemption date.

        Notice of any redemption will be mailed at least 30 days but not more
than 60 days before the redemption date to each Holder of the Notes to be
redeemed. Unless the Company defaults in payment of the redemption price, on and
after the redemption date, interest will cease to accrue on the Notes or
portions thereof called for redemption. If less than all of the Notes are to be
redeemed, the Notes (or portions thereof) to be redeemed shall be selected by
the Trustee by such method as the Trustee shall deem fair and appropriate.

        Notwithstanding the foregoing, installments of interest whose Stated
Maturity is prior to the Redemption Date of any Note will be payable to the
Holder of such Note, or one or more Predecessor Securities, of record at the
close of business on the relevant Regular Record Date referred to above, all as
provided in the Indenture.

        All notices of redemption shall state the Redemption Date, the
Redemption Price, if fewer than all the Outstanding Notes are to be redeemed,
the identification (and, in the case of partial redemption, the principal
amounts) of the particular Notes to be redeemed, that on the Redemption Date the
Redemption Price will become due and payable upon each Note, or portion thereof,
to be redeemed, that interest on each Note, or portion thereof, called for
redemption will cease to accrue on the Redemption Date and the place or places
where Notes may be surrendered for redemption. If fewer than all of the Notes
are to be redeemed at any time, selection of such Notes for redemption will be
made by the Trustee by such method as the Trustee shall deem fair and
appropriate.

        In the event of redemption of this Note in part only, a new Note or
Notes of like tenor for the unredeemed portion hereof will be issued in
authorized denominations in the name of the Holder hereof upon the cancellation
hereof.

        For all purposes of this Note and the Indenture, unless the context
otherwise requires, all provisions relating to the redemption by the Company of
this Note shall relate, in the case that this Note



                                       8

is redeemed or to be redeemed by the Company only in part to that portion of the
principal amount of this Note that has been or is to be redeemed.

        If an Event of Default with respect to Notes shall occur and be
continuing, the principal of the Notes may be declared due and payable in the
manner and with the effect provided in the Indenture.

        Notwithstanding any provision to the contrary in the Indenture or
otherwise, prior to the Remarketing Date, neither the Company nor any of its
subsidiaries or affiliates shall defease, purchase or otherwise acquire, or
enter into any agreement to defease, purchase or otherwise acquire, any of the
Notes prior to the remarketing thereof by the Remarketing Dealer.

        The Indenture permits, in certain circumstances therein specified, the
amendment thereof without the consent of the Holders of the Securities. The
Indenture also permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations under the
Indenture of the Company and the rights of Holders of the Securities of each
series to be affected under the Indenture at any time by the Company and the
Trustee with the consent of the Holders of a majority in aggregate principal
amount of the Securities at the time Outstanding of each series to be affected.
The Indenture also contains provisions permitting the Holders of a majority in
aggregate principal amount of the Securities of each series at the time
Outstanding, on behalf of the Holders of all the Securities of such series, to
waive compliance by the Company with certain provisions of the Indenture and
certain past defaults under the Indenture and their consequences. Any such
consent or waiver by the Holder of this Note shall be conclusive and binding
upon such Holder and upon all future Holders of this Note and of any Note issued
upon the registration of transfer hereof or in exchange herefor or in lieu
hereof, whether or not notation of such consent or waiver is made upon this
Note.

        No reference herein to the Indenture and no provision of this Note,
subject to the provisions for satisfaction and discharge in Article Four of the
Indenture, shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of and interest on this Note at
the times, place and rate, and in the coin or currency, herein prescribed.

        Notwithstanding any provision to the contrary set forth in the
Indenture, the Company shall use its commercially reasonable efforts to maintain
the Notes in book-entry form with DTC or any successor thereto and to appoint a
successor depositary to the extent necessary to maintain the Notes in book-entry
form. The Company hereby waives any discretionary right it otherwise has under
the Indenture to cause the Notes to be issued in certificated form prior to the
Remarketing Date.

        After the Remarketing Date, the Indenture permits the Company, by
irrevocably depositing, in amounts and maturities sufficient to pay and
discharge at the Stated Maturity or Redemption Date, as the case may be, the
entire indebtedness on all Outstanding Notes, cash or U.S. Government
Obligations with the Trustee in trust solely for the benefit of the Holders of
all Outstanding Notes, to defease the Indenture with respect to such Notes, and
upon such deposit the Company shall be deemed to have paid and discharged its
entire indebtedness on such Notes. Thereafter, Holders would be able to look
only to such trust fund for payment of principal and interest at the Stated
Maturity or Redemption Date, as the case may be.

        As provided in the Indenture and subject to certain limitations therein
set forth, the transfer of Notes is registrable in the Security Register, upon
surrender of a Note for registration of transfer at the Corporate Trust Office
of the Trustee or at the office or agency of the Trustee in the Borough of
Manhattan, The City of New York, or at such other offices or agencies as the
Company may designate, duly endorsed by, or accompanied by a written instrument
of transfer in form satisfactory to the Company and the Security Registrar duly
executed by, the Holder hereof or his attorney duly authorized in writing, and
thereupon one or more new Notes of like tenor, of authorized denominations and
for the same aggregate principal amount, will be issued to the designated
transferee or transferees.

        No service charge shall be made by the Company, the Trustee or the
Security Registrar for any such registration of transfer or exchange, but the
Company may require payment of a sum sufficient to cover any tax or other
governmental charge payable in connection therewith (other than exchanges
pursuant to Sections 304, 906 or 1107 of the Indenture, not involving any
transfer).

        Prior to due presentment of this Note for registration of transfer, the
Company, the Trustee and any agent of the Company or the Trustee may treat the
Person in whose name this Note is registered as the owner hereof for all
purposes, whether or not this Note be overdue, and neither the Company, the
Trustee nor any such agent shall be affected by notice to the contrary.

        The Indenture and the Notes shall be governed by and construed in
accordance with the laws of the State of New York.

        All undefined terms used in this Note which are defined in the Indenture
shall have the meanings assigned to them in the Indenture.

            Re:    Prospectus Supplement dated April 2, 1998 to
                   Prospectus dated March 26, 1998 (respectively, the
                   "Prospectus Supplement" and the "Prospectus")

Ladies and Gentlemen:

        We have acted as counsel for Occidental Petroleum Corporation, a
Delaware corporation (the "Company"), in connection with the preparation of the
above captioned Prospectus and Prospectus Supplement filed on April 3, 1998 with
the Securities and Exchange Commission (the "Commission") pursuant to Rule
424(b) of the Securities Act of 1933, as amended (the "Securities Act"). The
Prospectus Supplement relates to the issuance and sale by the Company of (i)
$250,000,000 aggregate principal amount of its 6.50% Senior Notes due April 1,
2005, (ii) $200,000,000 aggregate principal amount of its 7.20% Senior
Debentures due April 1, 2028 and (iii) $450,000,000 aggregate principal amount
of its 6.40% Senior Notes due April 1, 2013, Mandatorily Tendered on April 1,
2003 (collec tively, the "Debt Securities"). The Debt Securities were registered
pursuant to a Registration Statement on Form S-3 (File No. 33-59395) declared
effective by the Commission on July 12, 1995 and a Registration Statement on
Form S-3 (File No. 333-49207) filed with the Commission on April 2, 1998
pursuant to Rule 462(b) of the Securities Act.

        This opinion is delivered in accordance with the requirements of Item
601(b)(8) of Regulation S-K under the Securities Act.

        We hereby confirm that, although the discussions set forth in the above
captioned Prospectus and Prospectus Supplement under the headings "UNITED STATES
TAXATION" and "Certain United States Federal Tax Considerations," respectively,
do not purport to discuss all possible United States federal income tax
consequences of the purchase, ownership, and disposition of the Debt Securities,
in our opinion such discussions together constitute, in all material respects, a
fair and accurate summary of the United States federal income tax consequences
of the purchase, ownership, and disposition of Debt Securities, based upon
current law and subject to the qualifications set forth therein. There can be no
assurances that any of the opinions expressed herein will be accepted by the
Internal Revenue Service, or if challenged, by a court. This opinion is
expressed as of the date hereof unless otherwise expressly stated and applies
only to the disclosure under the headings "UNITED STATES TAXATION" and "Certain
United States Federal Tax Considerations" set forth in the Prospectus and the
Prospectus Supplement, respectively, and it assumes that any instrument that is
issued thereunder will have terms identical to those set forth in such
Prospectus or Prospectus Supplement. We disclaim any undertaking to advise you
of any subsequent changes of the facts stated or assumed herein or any
subsequent changes in applicable law.

        This opinion is furnished to you solely for your benefit in connection
with the preparation of the Prospectus and Prospectus Supplement and, except as
set forth below, is not to be used, circulated, quoted or otherwise referred to
for any other purpose or relied upon by any other person for any purpose without
our prior written consent. We hereby consent to the use of our name under the
headings "Legal Matters" in the Prospectus and the Prospectus Supplement. In
giving this consent, we do not thereby admit that we are within the category of
persons whose consent is required under Section 7 of the Securities Act or the
rules and regulations of the Commission promulgated thereunder.


                               Very truly yours,


                               /s/ Skadden, Arps, Slate, Meagher & Flom LLP
