                OCCIDENTAL PETROLEUM CORPORATION AND SUBSIDIARIES
              NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

                                 March 31, 2000

1.   General

     The accompanying unaudited consolidated condensed financial statements have
     been prepared by Occidental Petroleum Corporation (Occidental) pursuant to
     the rules and regulations of the Securities and Exchange Commission.
     Certain information and disclosures normally included in notes to
     consolidated financial statements have been condensed or omitted pursuant
     to such rules and regulations, but resultant disclosures are in accordance
     with generally accepted accounting principles as they apply to interim
     reporting. The consolidated condensed financial statements should be read
     in conjunction with the consolidated financial statements and the notes
     thereto in Occidental's Annual Report on Form 10-K for the year ended
     December 31, 1999 (1999 Form 10-K).

     In the opinion of Occidental's management, the accompanying consolidated
     condensed financial statements contain all adjustments (consisting only of
     normal recurring adjustments) necessary to present fairly Occidental's
     consolidated financial position as of March 31, 2000, and the consolidated
     results of operations and cash flows for the three months then ended. The
     results of operations and cash flows for the period ended March 31, 2000,
     are not necessarily indicative of the results of operations or cash flows
     to be expected for the full year.

     Certain financial statements and notes for the prior year have been changed
     to conform to the 2000 presentation.

     Reference is made to Note 1 to the consolidated financial statements in the
     1999 Form 10-K for a summary of significant accounting policies.

2.   Comprehensive Income

     The following table presents Occidental's comprehensive income items (in
     millions):

3.   Asset Acquisitions and Dispositions

     Reference is made to Note 3 to the consolidated financial statements in the
     1999 Form 10-K for a description of asset acquisitions and dispositions.

     In December 1999, Occidental entered into an agreement to sell its
     producing properties in Peru to Pluspetrol. The transaction, which was
     subject to governmental approval, closed on May 8, 2000. In connection with
     this transaction, Occidental recorded an after-tax charge of approximately
     $29 million in December 1999 to write-down the properties to their fair
     values.

4.   Supplemental Cash Flow Information

     Cash payments during the three months ended March 31, 2000 and 1999
     included federal, foreign and state income taxes of approximately $109
     million and $25 million, respectively. Interest paid (net of interest
     capitalized) totaled approximately $96 million and $90 million for the
     three months ended March 31, 2000 and 1999, respectively.

5.   Cash and Cash Equivalents

     Cash equivalents consist of highly liquid money-market mutual funds and
     bank deposits with maturities of three months or less when purchased. Cash
     equivalents totaled $58 million and $162 million at March 31, 2000, and
     December 31, 1999, respectively.

6.   Inventories

     A portion of inventories is valued under the LIFO method. The valuation of
     LIFO inventory for interim periods is based on management's estimates of
     year-end inventory levels and costs. Inventories consist of the following
     (in millions):

     Trust Preferred Securities balances reflected in the consolidated financial
     statements at March 31, 2000, and December 31, 1999, are net of issue costs
     and also reflect amortization of a portion of the issue costs, and the
     repurchase during 2000 and 1999 of 298,373 shares and 937,436 shares with
     liquidation values of $7.5 million and $23.4 million, respectively.

9.   Retirement Plans and Postretirement Benefits

     Reference is made to Note 14 to the consolidated financial statements in
     the 1999 Form 10-K for a description of the retirement plans and
     postretirement benefits of Occidental and its subsidiaries.

10.  Lawsuits, Claims, Commitments, Contingencies and Related Matters

     Occidental and certain of its subsidiaries have been named as defendants or
     as potentially responsible parties in a substantial number of lawsuits,
     claims and proceedings, including governmental proceedings under the
     Comprehensive Environmental Response, Compensation and Liability Act
     (CERCLA) and corresponding state acts. These governmental proceedings seek
     funding, remediation and, in some cases, compensation for alleged property
     damage, punitive damages and civil penalties, aggregating substantial
     amounts. Occidental is usually one of many companies in these proceedings,
     and has to date been successful in sharing response costs with other
     financially sound companies. Occidental has accrued reserves at the most
     likely cost to be incurred in those proceedings where it is probable that
     Occidental will incur remediation costs which can be reasonably estimated.

     In December 1998, David Croucher and others filed a purported class action
     suit in the Federal District Court in Houston, Texas on behalf of persons
     claiming to have been beneficiaries of the MidCon Employee Stock Ownership
     Plan (ESOP). The plaintiffs allege that each of the U.S. Trust Company of
     California (the ESOP Trustee) and the MidCon ESOP Administrative Committee
     breached its fiduciary duty to the plaintiffs by failing to properly value
     the securities held by the ESOP, and allege that Occidental actively
     participated in such conduct. The plaintiffs claim that, as a result of
     this alleged breach, the ESOP participants are entitled to an additional
     aggregate distribution of at least $200 million and that Occidental has
     been unjustly enriched and is liable for failing to make that distribution.

     During the course of its operations, Occidental is subject to audit by
     taxing authorities for varying periods in various tax jurisdictions.
     Occidental has certain other commitments under contracts, guarantees and
     joint ventures, and certain other contingent liabilities.

     It is impossible at this time to determine the ultimate liabilities that
     Occidental and its subsidiaries may incur resulting from the foregoing
     lawsuits, claims and proceedings, audits, commitments, contingencies and
     related matters. Several of these matters may involve substantial amounts,
     and if these were to be ultimately resolved unfavorably to the full amount
     of their maximum potential exposure, an event not currently anticipated, it
     is possible that such event could have a material adverse effect upon
     Occidental's consolidated financial position or results of operations.
     However, in management's opinion, after taking into account reserves, it is
     unlikely that any of the foregoing matters will have a material adverse
     effect upon Occidental's consolidated financial position or results of
     operations.

     Reference is made to Note 9 to the consolidated financial statements in the
     1999 Form 10-K for information concerning Occidental's long-term purchase
     obligations for certain products and services.

11.  Income Taxes

     The provision for taxes based on income for the 2000 and 1999 interim
     periods was computed in accordance with Interpretation No. 18 of APB
     Opinion No. 28 on reporting taxes for interim periods and was based on
     projections of total year pretax income.

     At December 31, 1999, Occidental had, for U.S. federal income tax return
     purposes, an alternative minimum tax credit carryforward of $60 million
     available to reduce future income taxes. The alternative minimum tax credit
     carryforward does not expire.

12.  Investments

     Investments in entities, other than oil and gas exploration and production
     companies, in which Occidental has a voting stock interest of at least 20
     percent, but not more than 50 percent, and certain partnerships are
     accounted for on the equity method. At March 31, 2000, Occidental's equity
     investments consisted primarily of a 29.5 percent interest in Equistar
     acquired in May 1998, an investment of 29.2 percent in the common shares of
     Canadian Occidental Petroleum Ltd. (CanOxy) and various chemical
     partnerships and joint ventures. The following table presents Occidental's
     proportionate interest in the summarized financial information of its
     equity method investments (in millions):

14.  Subsequent Events

     On April 18, 2000, Occidental completed the sale of its 29.2 percent stake
     in CanOxy for gross proceeds of approximately $1.2 billion Canadian,
     following approval of the sale by CanOxy stockholders. Of Occidental's 40.2
     million shares of CanOxy, 20.2 million were sold to the Ontario Teachers
     Pension Plan Board and 20 million to CanOxy. In addition, Occidental and
     CanOxy exchanged their respective 15 percent interests in joint businesses
     of approximately equal value, resulting in Occidental owning 100 percent of
     an oil and gas operation in Ecuador and CanOxy owning 100 percent of a
     sodium chlorate operation in Canada and Louisiana.

     On April 19, 2000, Occidental completed its acquisition of all of the
     common interest in Altura, the largest oil producer in Texas. Occidental,
     through its subsidiaries, paid approximately $1.2 billion to the sellers,
     affiliates of BP Amoco plc and Shell Oil Company, to acquire the common
     limited partnership interest and control of the general partner which
     manages, operates and controls 100 percent of the Altura assets. The
     partnership borrowed approximately $2.4 billion, which has recourse only to
     the Altura assets. The partnership also loaned approximately $2.0 billion
     to affiliates of the sellers, evidenced by two notes, which provide credit
     support to the partnership. The sellers retained a preferred limited
     partnership interest of approximately $2.0 billion and are entitled to
     certain distributions from the partnership. The acquisition is valued at
     approximately $3.6 billion.

     On April 24, 2000, Occidental completed the acquisition of ARCO Long Beach
     Inc., owner of the Long Beach Unit's operating contractor, THUMS, for
     approximately $57 million.

     On April 25, 2000, Occidental announced that it will call for redemption on
     June 1, 2000, all of its outstanding 11-1/8% Senior Debentures due June 1,
     2019, at a redemption price of 100% of the principal amount thereof. The
     outstanding aggregate principal amount is $75 million; the Debentures were
     issued on May 15, 1989.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

RESULTS OF OPERATIONS

Occidental Petroleum Corporation (Occidental) reported net income for the first
quarter of 2000 of $271 million, on net sales of $2.5 billion, compared with a
net loss of $70 million, on net sales of $1.3 billion, for the same period of
1999. Basic earnings per common share were income of $.74 for the first quarter
of 2000, compared with a loss of $.21 for the same period of 1999.

Earnings before special items were $264 million for the first quarter of 2000,
compared with a loss before special items of $68 million for the first quarter
of 1999. The first quarter of 1999 included an after-tax charge of $13 million,
reflecting the cumulative effect of adopting accounting principles changes
mandated by the American Institute of Certified Public Accountants and the
Emerging Issues Task Force of the Financial Accounting Standards Board.

The increase in net sales in the first quarter of 2000, compared with the same
period in 1999, primarily reflected higher oil and gas prices and higher prices
and sales volume for most of Occidental's chemical products. Minority interest
includes distributions on the Trust Originated Preferred Securities (Trust
Preferred Securities) and the minority interest in the net income of
subsidiaries and partnerships. The income from equity investments for the three
months ended March 31, 2000 compared with losses from equity investments for the
same period in 1999, was the result of higher worldwide crude oil prices and
improved export prices for vinyl chloride monomer (VCM). The provision for
income taxes increased to $296 million for the first quarter of 2000, compared
with $41 million for the same period in 1999, primarily due to higher earnings
in 2000.

The following table sets forth the sales and earnings of each industry segment
and corporate items (in millions):

Oil and gas earnings for the first quarter of 2000 were $394 million, compared
with $65 million for the same period of 1999. Higher worldwide crude oil and
natural gas prices contributed to an increase in quarterly earnings for oil and
gas. Operating and overhead costs were also lower in 2000. However, lower
production volumes, mainly resulting from the pending agreement to sell
producing assets in Peru, partially offset the overall improvement in earnings
from the prior year.

                                       11


Chemical earnings for the first quarter of 2000 were $143 million, compared with
$12 million for the same period of 1999. The increased earnings in 2000 resulted
primarily from higher prices and higher sales volume for VCM, ethylene
dichloride (EDC), polyvinyl chloride (PVC) resins and chlorine. Partially
offsetting these increases were higher raw material costs.

Divisional earnings include credits in lieu of U.S. federal income taxes. In the
first quarter of 2000 and 1999, divisional earnings benefited by $5 million and
$6 million, respectively, from credits allocated. This included credits of $1
million and $4 million at oil and gas and chemical, respectively, in the first
quarter of 2000 and $2 million and $4 million at oil and gas and chemical,
respectively, for the first quarter of 1999.

Occidental and certain of its subsidiaries have been named as defendants or as
potentially responsible parties in a substantial number of lawsuits, claims and
proceedings, including governmental proceedings under the Comprehensive
Environmental Response, Compensation and Liability Act (CERCLA) and
corresponding state acts. These governmental proceedings seek funding,
remediation and, in some cases, compensation for alleged property damage,
punitive damages and civil penalties, aggregating substantial amounts.
Occidental is usually one of many companies in these proceedings, and has to
date been successful in sharing response costs with other financially sound
companies. Occidental has accrued reserves at the most likely cost to be
incurred in those proceedings where it is probable that Occidental will incur
remediation costs which can be reasonably estimated.

During the course of its operations, Occidental is subject to audit by taxing
authorities for varying periods in various tax jurisdictions. Occidental has
certain other commitments under contracts, guarantees and joint ventures, and
certain other contingent liabilities.

It is impossible at this time to determine the ultimate liabilities that
Occidental and its subsidiaries may incur resulting from the foregoing lawsuits,
claims and proceedings, audits, commitments, contingencies and related matters.
Several of these matters may involve substantial amounts, and if these were to
be ultimately resolved unfavorably to the full amount of their maximum potential
exposure, an event not currently anticipated, it is possible that such event
could have a material adverse effect upon Occidental's consolidated financial
position or results of operations. However, in management's opinion, after
taking into account reserves, it is unlikely that any of the foregoing matters
will have a material adverse effect upon Occidental's consolidated financial
position or results of operations.

FINANCIAL CONDITION, LIQUIDITY AND CAPITAL RESOURCES

Occidental's net cash provided by operating activities was $348 million for the
first quarter of 2000, compared with $75 million for the same period of 1999.
The 2000 amount is primarily attributed to higher net income before special
items. The improved earnings reflected the impact of higher oil and gas and
chemical prices. Changes in operating assets and liabilities reflected higher
net working capital usage in 2000 compared with 1999.

Occidental's net cash used by investing activities was $487 million for the
first quarter of 2000, compared with net cash provided of $1.299 billion for the
same period of 1999. The 2000 amount included a $375 million deposit for the
acquisition of the Altura Energy Ltd. Partnership (Altura) described below,
which was recorded in other assets. The 1999 amount included the proceeds from a
$1.4 billion note receivable received in connection with the sale of MidCon,
Occidental's natural gas pipeline subsidiary.

Financing activities provided net cash of $53 million in the first quarter of
2000, compared with cash used of $899 million for the same period of 1999. The
1999 amount reflected the use of the proceeds from the $1.4 billion note
receivable to repay approximately $1.3 billion in debt and for the payment of
dividends of $91 million. The 1999 amount also reflected net proceeds of $508
million from the issuance of the Trust Preferred Securities.

On April 24, 2000, Occidental completed the acquisition of ARCO Long Beach Inc.,
owner of the Long Beach Unit's operating contractor, THUMS, for approximately
$57 million. The acquisition adds approximately 95 million barrels of net oil
reserves and approximately 27,000 barrels per day of net oil production to
Occidental's growing California operations.

                                       12


On April 19, 2000, Occidental completed its acquisition of all of the common
interest in Altura, the largest oil producer in Texas. Occidental, through its
subsidiaries, paid approximately $1.2 billion to the sellers, affiliates of BP
Amoco plc and Shell Oil Company, to acquire the common limited partnership
interest and control of the general partner which manages, operates and controls
100 percent of the Altura assets. The partnership borrowed approximately $2.4
billion, which has recourse only to the Altura assets. The partnership also
loaned approximately $2.0 billion to affiliates of the sellers, evidenced by two
notes, which provide credit support to the partnership. The sellers retained a
preferred limited partnership interest of approximately $2.0 billion and are
entitled to certain distributions from the partnership. As a result of the
acquisition, which is valued at approximately $3.6 billion, Occidental's
worldwide oil and gas production is expected to increase by approximately
135,000 barrels per day of oil equivalent and Occidental's worldwide production
is expected to increase by 13 percent to an average of approximately 480,000
barrels of oil equivalent per day this year versus 425,000 barrels per day in
1999. Proved reserves at Altura were 850 million barrels of oil equivalent at
December 31, 1999. This acquisition will bring Occidental's proved reserves to
approximately 2.2 billion barrels of oil equivalent.

On April 18, 2000, Occidental completed the sale of its 29.2 percent stake in
Canadian Occidental Petroleum Ltd. (CanOxy) for gross proceeds of approximately
$1.2 billion Canadian, following approval of the sale by CanOxy stockholders. Of
Occidental's 40.2 million shares of CanOxy, 20.2 million were sold to the
Ontario Teachers Pension Plan Board and 20 million to CanOxy. In addition,
Occidental and CanOxy exchanged their respective 15 percent interests in joint
businesses of approximately equal value, resulting in Occidental owning 100
percent of an oil and gas operation in Ecuador and CanOxy owning 100 percent of
a sodium chlorate operation in Canada and Louisiana. Approximately $750 million
of combined after-tax proceeds from the CanOxy disposition and the disposition
of the Peru producing operations was applied to the acquisition of the Altura
and THUMS properties.

In December 1999, Occidental and EOG Resources, Inc. (EOG) exchanged certain oil
and gas assets. Occidental received producing properties and exploration acreage
in its expanding California asset base, as well as producing properties in the
western Gulf of Mexico near existing operations in exchange for oil and gas
production and reserves in east Texas. Occidental also farmed out Oklahoma
panhandle properties to EOG and retained a carried interest.

In December 1999, Occidental entered into an agreement to sell its producing
properties in Peru to Pluspetrol. The transaction, which was subject to
governmental approval, closed on May 8, 2000. In connection with this
transaction, Occidental recorded an after-tax charge of approximately $29
million in December 1999 to write-down the properties to their fair values.

In the third quarter of 1999, pursuant to a series of transactions, Occidental
indirectly acquired the remaining ownership of INDSPEC Chemical Corporation
(INDSPEC) through the issuance of approximately 3.2 million shares of Occidental
common stock at an estimated value of approximately $68 million and the
assumption of approximately $80 million of bank debt. As a result of the
transactions, Occidental owns 100 percent of the stock of INDSPEC.

In the third quarter of 1999, Occidental acquired Unocal International
Corporation's (UNOCAL) oil and gas interests in Yemen and UNOCAL acquired
Occidental's properties in Bangladesh.

Effective April 30, 1999, Occidental and The Geon Company (Geon) formed two
partnerships. Occidental has a 76 percent interest in the PVC commodity resin
partnership, OxyVinyls, LP (OxyVinyls), which is larger of the partnerships, and
a 10 percent interest in a PVC powder compounding partnership. OxyVinyls also
has entered into long-term agreements to supply PVC resin to Geon and VCM to
Occidental and Geon. In addition, as part of the transaction, Occidental sold
its pellet compounding plant in Pasadena, Texas and its vinyl film assets in
Burlington, New Jersey to Geon.

On April 25, 2000, Occidental announced that it will call for redemption on June
1, 2000, all of its outstanding 11-1/8% Senior Debentures due June 1, 2019, at a
redemption price of 100% of the principal amount thereof. The outstanding
aggregate principal amount is $75 million; the Debentures were issued on May 15,
1989.

                                       13


In February 1999, Occidental issued $450 million of 7.65 percent senior notes
due 2006 and $350 million of 8.45 percent senior notes due 2029 for net proceeds
of approximately $792 million.

In January 1999, a subsidiary of Occidental issued $525 million of 8.16 percent
Trust Preferred Securities due in 2039, for net proceeds of $508 million. The
net proceeds were used to repay commercial paper. The Trust Preferred Securities
balances reflected in the consolidated financial statements at March 31, 2000
and December 31, 1999 are net of issue costs and also reflect amortization of a
portion of the issue costs, and the repurchase during 2000 and 1999 of 298,373
shares and 937,436 shares with liquidation values of $7.5 million and $23.4
million, respectively.

Occidental expects to have sufficient cash in 2000 for its operating needs,
capital expenditure requirements, dividend payments and debt repayments.
Occidental currently expects to spend $950 million on its capital spending
program in 2000. Available but unused lines of committed bank credit totaled
approximately $2.0 billion at March 31, 2000, compared with $2.1 billion at
December 31, 1999. Subsequent to March 31, Occidental borrowed substantial
amounts to fund the Altura acquisition partially offset by proceeds from asset
dispositions.

YEAR 2000 COMPLIANCE

The Y2K program employed a five-step process consisting of: 1) conducting a
company-wide inventory; 2) assessing Y2K compliance; 3) remediating
non-compliant software and hardware, particularly hardware that employs embedded
chips such as process controls; 4) testing remediated hardware and software; and
5) certifying Y2K compliance.

The inventory and assessment activities continued throughout the Y2K program as
changes occurred. Overall remediation efforts were completed on schedule and
there were no significant adverse Y2K events.

Costs for Y2K efforts were not accumulated separately and much of the cost was
accounted for as part of normal operations. Overall, the costs were
approximately $29 million. The costs did not have a significant effect on
Occidental's consolidated financial position or results of operations.

Contingency plans that addressed a reasonably likely worst case scenario were
put in place. These plans also addressed and analyzed the resources necessary to
restore operations in the event an interruption occurred. No interruptions
caused by third parties occurred.

Because of these company-wide efforts, Occidental believes it took appropriate
actions to minimize the risk associated with Y2K to its operations and financial
condition. Occidental's operations moved into the year 2000 without interruption
and the Y2K program was considered a success.

ENVIRONMENTAL MATTERS

Occidental's operations in the United States are subject to stringent federal,
state and local laws and regulations relating to improving or maintaining the
quality of the environment. Foreign operations also are subject to varied
environmental protection laws. Costs associated with environmental compliance
have increased over time and may continue to rise in the future.

The laws which require or address environmental remediation apply retroactively
to previous waste disposal practices. And, in many cases, the laws apply
regardless of fault, legality of the original activities or ownership or control
of sites. Occidental is currently participating in environmental assessments and
cleanups under these laws at federal Superfund sites, comparable state sites and
other remediation sites, including Occidental facilities and previously owned
sites.

Occidental does not consider the number of Superfund and comparable state sites,
at which it has been notified that it has been identified as being involved, to
be a relevant measure of exposure. Although the liability of a potentially
responsible party (PRP), and in many cases its equivalent under state law, may
be joint and several, Occidental is

                                       14


usually one of many companies cited as a PRP at these sites and has, to date,
been successful in sharing cleanup costs with other financially sound companies.

As of March 31, 2000, Occidental had been notified by the Environmental
Protection Agency (EPA) or equivalent state agencies or otherwise had become
aware that it had been identified as being involved at 125 Superfund or
comparable state sites. (This number does not include those sites where
Occidental has been successful in resolving its involvement). The 125 sites
include 34 former Diamond Shamrock Chemical sites as to which Maxus Energy
Corporation has retained all liability. Of the remaining 91 sites, Occidental
has denied involvement at 10 sites and has yet to determine involvement in 20
sites. With respect to the remaining 61 of these sites, Occidental is in various
stages of evaluation, and the extent of liability retained by Maxus Energy
Corporation is disputed at 2 of these sites. For 54 of these sites, where
environmental remediation efforts are probable and the costs can be reasonably
estimated, Occidental has accrued reserves at the most likely cost to be
incurred. The 54 sites include 11 sites as to which present information
indicates that it is probable that Occidental's aggregate exposure is
immaterial. In determining the reserves, Occidental uses the most current
information available, including similar past experiences, available technology,
regulations in effect and the timing of remediation and cost-sharing
arrangements. For the remaining 7 of the 61 sites being evaluated, Occidental
does not have sufficient information to determine a range of liability, but
Occidental does have sufficient information on which to base the opinion
expressed above under the caption "Results of Operations."
