                                 PROXY STATEMENT
--------------------------------------------------------------------------------


GENERAL INFORMATION
--------------------------------------------------------------------------------

This Proxy Statement is furnished in connection with the solicitation of proxies
by the Board of Directors of Occidental Petroleum Corporation, a Delaware
corporation, for use at the Annual Meeting of Stockholders on May 6, 2005, and
at any adjournment of the meeting.

ADMISSION TO THE ANNUAL MEETING

Attendance is limited to stockholders and one guest per stockholder. If you plan
to attend the meeting in person and you are a stockholder of record, you must
bring the admission ticket attached to your proxy or information card. If your
shares are held in the name of a bank, broker or other holder of record and an
admission ticket is not part of your voting instruction card, you will be
admitted only if you have proof of ownership on the record date, such as a bank
or brokerage account statement. In addition to your admission ticket or account
statement, you may be asked to present valid picture identification, such as a
driver's license or passport.

VOTING RIGHTS

This Proxy Statement and accompanying proxy card are being mailed beginning on
or about March 15, 2005, to each stockholder of record as of March 3, 2005,
which is the record date for the determination of stockholders entitled to
receive notice of, to attend, and to vote at the meeting. As of the record date,
Occidental had outstanding and entitled to vote 398,244,371 shares of common
stock. A majority of outstanding shares must be represented at the meeting, in
person or by proxy, to constitute a quorum and to transact business. You will
have one vote for each share of Occidental's common stock you own. You may vote
in person at the meeting or by proxy. Proxies may be voted by completing and
mailing the proxy card, by telephone or Internet as explained on the proxy card.
You may not cumulate your votes.

VOTING OF PROXIES

The Board of Directors has designated Dr. Ray R. Irani, Mr. Aziz D. Syriani and
Miss Rosemary Tomich, and each of them, with the full power of substitution, to
vote shares represented by all properly executed proxies. The shares will be
voted in accordance with the instructions on the proxy card. If no instructions
are specified on the proxy card, the shares will be voted:

     o  FOR all nominees for directors (see page 2);

     o  FOR ratification of the independent auditors (see page 22);

     o  FOR adoption of the Occidental Petroleum Corporation 2005 Long-Term
        Incentive Plan (see page 22); and

     o  AGAINST Proposals 4 and 5 (stockholder proposals begin on  page 26).

In the absence of instructions to the contrary, proxies will be voted in
accordance with the judgment of the person exercising the proxy on any other
matter presented at the meeting in accordance with Occidental's By-laws.

BROKER VOTES

If your shares are held in street name, under New York Stock Exchange Rules,
your broker can vote your shares on any of the matters scheduled to come before
the meeting except the adoption of the Occidental Petroleum Corporation 2005
Long-Term Incentive Plan (Proposal 3) and the stockholder proposals (Proposals 4
and 5). If your broker does not have discretion and you do not give the broker
instructions, the votes will be broker nonvotes, which will have the same effect
as votes against the proposals.

VOTE REQUIRED

The vote required to elect directors and to approve each proposal is described
with the proposal.

VOTING RESULTS

The results of the vote will be published on Occidental's web site within 14
calendar days following the date of the meeting, in Occidental's Quarterly
Report on Form 10-Q for the quarter ended June 30, 2005, and in the Report on
the Annual Meeting, all of which may be accessed through www.oxy.com.


                                       1



CONFIDENTIAL VOTING

All proxies, ballots and other voting materials are kept confidential, unless
disclosure is required by applicable law or expressly requested by you, you
write comments on the proxy forms, or the proxy solicitation is contested.
Occidental's confidential voting policy is posted on www.oxy.com.

REVOKING A PROXY

You may revoke your proxy or change your vote before the meeting by filing a
revocation with the Secretary of Occidental, by delivering to Occidental a valid
proxy bearing a later date or by attending the meeting and voting in person.


SOLICITATION EXPENSES

Expense of this solicitation will be paid by Occidental. Morrow & Co., Inc. has
been retained to solicit proxies and assist in distribution and collection of
proxy material for a fee estimated at $15,000 plus reimbursement of
out-of-pocket expenses. Occidental also will reimburse banks, brokers, nominees
and related fiduciaries for the expense of forwarding soliciting material to
beneficial owners of the common stock. In addition, Occidental's officers,
directors and regular employees may solicit proxies but will receive no
additional or special compensation for such work.


PROPOSAL 1: ELECTION OF DIRECTORS
--------------------------------------------------------------------------------

Directors are elected by a plurality of votes. Your broker has discretionary
authority to vote for this proposal if you do not give instruction. Because the
number of nominees equals the number of directors to be elected, instructions to
"withhold" authority will have no effect on the results of the election.

Unless you specify differently on the proxy card, proxies received will be voted
FOR Spencer Abraham, Ronald W. Burkle, John S. Chalsty, Edward P. Djerejian, R.
Chad Dreier, John E. Feick, Dr. Ray R. Irani, Irvin W. Maloney, Rodolfo Segovia,
Aziz D. Syriani, Rosemary Tomich and Walter L. Weisman to serve for a one-year
term ending at the 2006 Annual Meeting, but in any event, until his or her
successor is elected and qualified, unless ended earlier due to his or her
death, resignation, disqualification or removal from office. In the event any
nominee should be unavailable at the time of the meeting, the proxies may be
voted for a substitute nominee selected by the Board of Directors.

The following biographical information is furnished with respect to each of the
nominees for election at the 2005 Annual Meeting.

The Board of Directors recommends a vote FOR all of the nominees.

INFORMATION REGARDING THE BOARD OF DIRECTORS AND ITS COMMITTEES

CORPORATE GOVERNANCE - In 2005, the Board amended and restated its Corporate
Governance Policies to reflect regulatory changes as well as the Board's desire
to maintain high standards for the governance of the Board and the Committees.
The Corporate Governance Policies, together with information about other
governance measures, are set forth in Exhibit A and are also available at
www.oxy.com.

INDEPENDENCE - Each of Miss Tomich and Messrs. Abraham, Burkle, Chalsty,
Djerejian, Dreier, Feick, Maloney, Segovia, Syriani and Weisman has been
determined by the Board of Directors as meeting the independence standard set
forth in Occidental's Corporate Governance Policies (see Exhibit A) and the New
York Stock Exchange Listed Company Manual. Except for the Executive Committee,
the Charitable Contributions Committee and the Dividend Committee, all
committees of the Board are composed of independent directors.

MEETINGS - The Board of Directors held six regular meetings during 2004,
including one executive session at which no members of management were present.
Mr. Syriani, the Lead Independent Director, presided over the executive session.
Each director attended at least 75 percent of the meetings of the Board of
Directors and the committees of which he or she was a member and all of the
directors, except Mr. Syriani, attended the 2004 Annual Meeting. Attendance at
the annual meeting of stockholders is expected of all directors as if it were a
regular meeting.

COMMUNICATIONS WITH BOARD MEMBERS - Stockholders and other interested parties
may communicate with any director by sending a letter to such director's
attention in care of Occidental's Corporate Secretary, 10889 Wilshire Blvd., Los
Angeles, California 90024. The Corporate Secretary opens, logs and forwards all
such correspondence (other than advertisements or other solicitations) to
directors unless the director to whom the correspondence is addressed has
requested the Corporate Secretary to forward correspondence unopened.

LEAD INDEPENDENT DIRECTOR AND COMMITTEES - The Board of Directors has a Lead
Independent Director and seven standing committees: Executive; Audit; Corporate
Governance, Nominating and Social Responsibility; Charitable Contributions;
Dividend; Executive Compensation and Human Resources; and Environmental, Health
and Safety. The Audit Committee Charter, the Executive Compensation and Human
Resources Committee Charter and the Corporate Governance, Nominating and Social
Responsibility Committee Charter and the enabling resolutions for each of the
other committees are available at www.oxy.com. The general duties of the Lead
Independent Director and the committees are described below. From time to time,
the Board of Directors delegates additional duties to the standing committees.

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Pursuant to Section 16(a) of the Securities Exchange Act of 1934 and the rules
issued thereunder, Occidental's executive officers, directors and any beneficial
owner of more than 10 percent of any class of Occidental's equity securities are
required to file with the Securities and Exchange Commission and the New York
Stock Exchange reports of ownership and changes in ownership of common stock.
Copies of such reports are required to be furnished to Occidental. Based solely
on its review of the copies of the reports furnished to Occidental, or written
representations that no reports were required, Occidental believes that, during
2004, all persons required to report complied with the Section 16(a)
requirements.



SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

At the close of business on March 3, 2005, the beneficial owners of common stock
shown below were the only persons known to Occidental to be the beneficial

     (1) Does not include the cost of security services that Occidental believes
are required to safeguard its executive officers. Such security costs in 2004
aggregated $915,384 for the named executive officers. Since 2002, the named
executive officers reimburse Occidental for any personal use of company
aircraft, including guests accompanying an executive on a flight being taken by
the executive for a business purpose, at the standard industry fare level, which
rate is intended to approximate first class airfare. The amounts in this column
include the excess, if any, of the estimated incremental cost of using the
aircraft and the amount reimbursed by the executive. A zero in the column means
that the executive did not receive perquisites or other personal benefits,
securities or property exceeding $50,000 in that year.

     (2) Includes restricted stock unit awards made in July and December 2004 to
the executive officers listed pursuant to the Occidental Petroleum Corporation

July award and a five-year vesting period for the December award. During the
vesting period, dividend equivalents are credited on the restricted stock units
in an amount equal to the per share dividend declared per share of common stock
and cash equal to the dividend equivalent is paid to the grantee. As of December
31, 2004, Dr. Irani held an aggregate of 727,587 restricted shares and units,
having a value of $42,461,977; Dr. Laurance 249,851 shares and units, having a

     (1) In July 2004, each of the named executive officers, other than Dr.
Laurance, received a simultaneous grant of Incentive Stock Options ("ISOs")
Non-qualified Stock Options ("NQSOs") and Stock Appreciation Rights (SARs). The
ISOs are listed first in the table, the NQSOs are listed second and the SARs are
listed third. The ISOs, NQSOs and SARs were granted subject to a three-year
vesting period, with approximately one-third of each grant becoming exercisable
each year commencing on the first anniversary of the grant date and ending on
the third anniversary. The SARs are exercisable only for cash. The vesting and
exercisability of the options and SARs will be accelerated in the event of a
Change of Control (as defined in the 2001 Incentive Compensation Plan).

     (2) Options and SARs are granted at market price on the day of the grant.
The exercise price and tax withholding obligations related to exercise of
options may be paid by delivery of already owned shares or by offset of the
underlying shares, subject to certain conditions.

     (3) The options and SARs were granted for terms of 10 years. Upon the
termination of the recipient's employment, the options and SARs continue to vest
and remain exercisable (depending on the cause of termination) for a period of
up to the remaining term of each option and SAR. However, under the provisions
of his employment agreement, the options and SARs granted to Dr. Irani become
fully vested immediately in the event of termination by Occidental or his
retirement and are then exercisable for the remaining term of the award. Under
the terms of their respective employment agreements, the options and SARs
granted to Messrs. Chazen and de Brier continue to vest in the event of
termination by Occidental and are exercisable for the remaining term of the
agreement. See "Employment Agreements" below.

     (4) The dollar amounts in these columns are the result of calculations at
the 5 percent and 10 percent annual appreciation rates for the term of the
options and SARs (10 years) as required by the Securities and Exchange
Commission, and therefore are not intended to predict future appreciation, if
any, in the price of Occidental common stock.

     (1) Performance Stock Awards were made in January 2004 pursuant to the 2001
Incentive Compensation Plan. The number of shares received at the end of the
performance period will depend on the attainment of performance objectives based
on a peer company comparison of total stockholder return. Depending on
Occidental's ranking among its peers and subject to the grantee remaining
employed throughout the performance period, the grantee receives shares of
common stock in an amount ranging from 0 percent to 200 percent of the Target
Share Award; provided, however, if the grantee dies, becomes disabled, retires
or is terminated for the convenience of Occidental during the performance
period, then the grantee will forfeit the right to receive a pro rata portion of
the payout based on the days remaining in the performance period after such
event. During the performance period, dividend equivalents are credited on the
Target Shares in an amount equal to the per share dividend declared per share of
common stock and cash equal to the dividend equivalent is paid to the grantees.
In the event of a Change of Control (as defined in the 2001 Incentive
Compensation Plan), the grantee's right to receive the number of Target Shares
becomes nonforfeitable.

     (2) Under the terms of his employment agreement, any long-term incentive
awards granted to Dr. Irani become fully vested immediately in the event of
termination by Occidental or his retirement. See "Employment Agreements" below.

     (3) Under the terms of his employment agreement, any long-term incentive
awards granted to Dr. Laurance became fully vested upon his retirement. See
"Employment Agreements" below.

     (4) Under the terms of their respective employment agreements, the
performance period for the entire award granted to Messrs. Chazen and de Brier
continues in the event of termination without cause for the remaining term of
the agreement. See "Employment Agreements" below.


EMPLOYMENT AGREEMENTS

The following are summaries of the employment agreements between Occidental and
the executive officers named in the Compensation Tables, except Mr. Morgan, who
does not have an employment agreement. Copies of the agreements are available as
exhibits to Occidental's periodic reports filed with the Securities and Exchange
Commission.

DR. IRANI - On February 10, 2005, Occidental Petroleum Corporation
("Occidental") entered into an amended and restated employment agreement with
Dr. Irani. The agreement, as amended, is for a term expiring on the earlier of
Occidental's 2010 Annual Meeting of Stockholders or May 30, 2010, with an annual
salary at a minimum rate of $1,300,000, subject to annual increase (and, as part
of across-the-board reductions for other officers, decrease), as well as an
annual cash bonus, in each case at the reasonable discretion of the Board of
Directors and the Executive Compensation and Human Resources Committee (the
"Committee"). Salary increase and bonuses may be paid at the discretion of the
Committee in cash, common stock or a combination thereof. In addition, Dr. Irani
is eligible to participate in Occidental's group life insurance, medical and
dental care (including coverage for his wife and children), disability,
retirement, personal savings account, deferred compensation and other plans or
benefits which Occidental may provide for employees and other senior executives.
During the term and thereafter until his death, Dr. Irani will receive life
insurance at least equal to three times his highest career annual salary, which
life insurance shall be assignable at Dr. Irani's option. Prior to retirement,
Dr. Irani will receive six weeks paid vacation each calendar year (which will
accrue and for which he will be entitled to be paid for any accrued but unused
vacation time upon termination of the agreement) and the minimum perquisites to
which he was entitled prior to November 30, 2000. See also footnote (5) to the
Summary Compensation Table on page 11 for information on perquisites received by
Dr. Irani.

Following his retirement or upon the termination of his employment by
Occidental, Dr. Irani will continue to receive medical and dental benefits no
less favorable than those provided prior to his retirement or termination and
his exiting perquisites, including the personal tax, accounting and financial
planning services currently provided to him. Upon retirement, notwithstanding
the provisions of the award agreements, all of Dr. Irani's unvested stock
options, SARs and restricted stock awards will immediately vest and become
exercisable and his performance stock awards will become immediately vested and
fully payable. If the agreement is terminated due to Dr. Irani's death, Dr.
Irani's estate will be entitled to a pro rata portion of any bonus he was
eligible to receive for the year of his death. If Dr. Irani is married at the
time of his death, his wife will be entitled, for the remainder of her life, to
continuation of medical benefits. If Dr. Irani is terminated by Occidental for
any reason, or if Dr. Irani terminates employment because Occidental materially
breaches the agreement, Dr. Irani is entitled to receive three times his highest
annual salary and bonus for any calendar year commencing with January 1, 2000
(subject to certain offsets of disability benefits in the case of termination
due to disability), without obligation to mitigate, payable in an undiscounted
lump sum not later than two and one half months from the end of the calendar
year in which the termination occurs. In such event of termination, Dr. Irani is
also entitled to receive his medical, dental, welfare and life insurance
benefits; his existing perquisites and the full and immediate vesting of his
restricted stock, stock options and any other long-term incentive benefits;
provided that the options or stock appreciation rights shall be exercisable as
if he had retired on such date. If after termination of his employment Dr. Irani
is not eligible to participate in Occidental's benefit plans as contemplated by
his employment agreement, then Occidental will provide Dr. Irani with
substantially equivalent benefits and will reimburse him for any additional tax
liabilities incurred by him as a result of his receipt of such benefits. If
Occidental materially breaches the agreement and does not cure the breach after
notice thereof, Dr. Irani may terminate his employment and treat such occurrence
as if it were a termination by Occidental; provided that it shall not be a
material breach if, following the merger or sale of Occidental or substantially
all of its assets, Dr. Irani continues to have substantially the same executive
duties and reports to the acquirer's board of directors. The agreement also
holds Dr. Irani harmless from the effects of any excise or other taxes payable
under or as a result of Sections 280G and 4999 of the Internal Revenue Code of
1986 or comparable state law by reason of a change of control, including taxes
payable on any amounts paid pursuant to this hold harmless provision. During and
after the term of the agreement, Dr. Irani is entitled to the payment of all
legal fees other than those of a purely personal nature. In addition, the
agreement provides for additional indemnification for Dr. Irani to the fullest
extent permitted by applicable law and for Occidental to maintain Directors' and
Officers' liability insurance with policy limits aggregating not less than $100
million, insuring Dr. Irani against occurrences which occur during the term of
the agreement.


                                       13



DR. LAURANCE - On July 19, 2004, Dr. Laurance entered into an amendment to his
November 17, 2000 employment agreement with Occidental to provide for his phased
retirement and a Consulting Agreement, effective as of January 1, 2005 (the
"Consulting Agreement"), to provide for his continued availability to Occidental
as a consultant following retirement. Under the terms of his amended employment
agreement (the "Amended Agreement"), Dr. Laurance continued to serve as
President of Occidental through December 31, 2004. For the period prior to his
retirement, the Amended Agreement provided for an annual salary at a minimum
rate of $990,000, as well as a discretionary annual cash bonus and participation
in Occidental's qualified and nonqualified retirement plans, its incentive stock
plan, deferred compensation plan and any future performance plans adopted by
Occidental as well as any group life insurance, medical care (including coverage
for his wife and children), disability and other plans or benefits which
Occidental provided for him.

Following his retirement, pursuant to the Amended Agreement, Dr. Laurance will
continue to receive life insurance equal to twice his highest career annual
salary, medical benefits no less favorable than those provided to Dr. Laurance
prior to such retirement or termination, and the personal tax, accounting and
financial planning services he previously received. (See footnote (7) to the
Summary Compensation Table on page 11.) Upon his retirement, his restricted
stock, stock options and any other long-term incentive benefits became fully and
immediately vested; provided that the amounts, if any, to be paid in respect of
any performance stock awards will be determined by the Executive Compensation
and Human Resources Committee at the end of the relevant performance period for
each such award. If after his retirement, Dr. Laurance is not eligible to
participate in Occidental's benefit plans as contemplated by the Amended
Agreement, then Occidental will provide Dr. Laurance with substantially
equivalent benefits and will reimburse him for any additional tax liabilities
incurred by him as a result of his receipt of such benefits. The Amended
Agreement also holds Dr. Laurance harmless from the effects of any excise or
other taxes payable under or as a result of Sections 280G and 4999 of the
Internal Revenue Code of 1986 or comparable state law by reason of a change of
control, including taxes payable on any amounts paid pursuant to this hold
harmless provision. Following his retirement, Dr. Laurance is entitled to the
payment of all legal fees other than those of a purely personal nature. In
addition, the Amended Agreement provides for additional indemnification for Dr.
Laurance to the fullest extent permitted by applicable law and for Occidental to
maintain Directors' and Officers' liability insurance with policy limits
aggregating not less than $100 million, insuring Dr. Laurance against
occurrences which occurred prior to his retirement.

Pursuant to the Consulting Agreement, Dr. Laurance will serve as a consultant to
Occidental through December 31, 2009, at a monthly retainer of $41,667. During
the term of the Consulting Agreement, Occidental will reimburse Dr. Laurance for
his expenses incurred in providing his services, including providing him with
one full-time secretary and information and telecommunications services
equivalent to that he used during his employment at Occidental. The expenses for
secretarial, information and telecommunications services are expected to total
approximately $192,000 per year. Dr. Laurance will also receive life insurance
coverage in the amount of $1,030,000 during the term of the Consulting Agreement
in addition to the coverage provided under the Amended Agreement and will be
entitled to use of the Occidental corporate aircraft on a "when available"
basis, subject to his obligation to reimburse Occidental for such use when it is
used for personal matters on the same terms and conditions applicable to vice
presidents of Occidental. The Consulting Agreement may be terminated by
Occidental for cause or by Dr. Laurance upon 30 days notice.

MR. CHAZEN - On January 13, 2005, Occidental Petroleum Corporation entered into
a new employment agreement with Mr. Chazen, replacing his prior agreement which
would have terminated in October 2005. The new agreement is for a term expiring
in January 2010, and provides for an annual salary of not less than $720,000. In
addition, the agreement provides that Mr. Chazen will be eligible to participate
in all benefit programs as are generally applicable to all salaried employees
and senior executives during the term of the agreement. Mr. Chazen may terminate
the agreement at any time upon 60 days notice. Occidental may discharge Mr.
Chazen and terminate the agreement for material cause without severance or other
pay upon 30 days' written notice. If Mr. Chazen's employment is terminated as a
result of incapacity and he is a participant in and qualifies for benefits under
Occidental's Long-Term Disability Plan, Occidental will pay Mr. Chazen the
difference between 60 percent of his annual salary and the maximum annual
disability benefit, for so long as he remains eligible to receive disability
benefits. In the event he is terminated without cause, Mr. Chazen will receive
an amount equal to twice the sum of his highest base salary and annual cash
bonus target, which amount is payable over a two-year compensation period.
During the compensation period, Mr. Chazen will continue to be eligible to
participate in all employee benefit plans available to salaried employees and
senior executives and to exercise stock options and stock appreciation rights
previously granted him that are or become exercisable. Following the
compensation period, Mr. Chazen will continue as a consultant to Occidental
until January 2010, at an annual salary of $50,000. During the compensation
period and any consultancy period, any stock-based awards granted prior to Mr.
Chazen's termination will continue to vest in the same manner and in the same
amounts as if he continued as a full-time employee.


                                       14



MR. DE BRIER - Mr. de Brier has an employment agreement with Occidental for a
term expiring in May 2008, providing for an annual salary of not less than
$551,000. If Mr. de Brier's employment is terminated as a result of incapacity
and he is a participant in and qualifies for benefits under Occidental's
Long-Term Disability Plan, Occidental will pay Mr. de Brier the difference
between 60 percent of his annual salary and the maximum annual disability
benefit, for so long as he remains eligible to receive disability benefits. In
the event he is terminated without cause, Mr. de Brier will receive an amount
equal to twice the sum of his highest base salary and annual cash bonus target,
which amount is payable in equal monthly installments over a two-year
compensation period. During the compensation period, Mr. de Brier will continue
to be eligible to participate in all employee benefit plans available to
salaried employees and senior executives and to exercise options previously
granted him that are or become exercisable. During the compensation period, any
stock awards granted prior to Mr. de Brier's termination will continue to vest
in the same manner and in the same amounts as if he continued as a full-time
employee.

BENEFIT PLANS

The following is a summary of the benefit plans made available to executives and
other eligible employees of Occidental.

DEFERRED COMPENSATION PLAN - The Occidental Petroleum Corporation Deferred
Compensation Plan permits executives and other eligible employees to defer up to
75 percent of their base salaries and up to 100 percent of their annual
incentives each year. Deferral elections are irrevocable and must be made prior
to the period during which the deferred compensation will be earned. Deferred
amounts earn interest equal to Moody's Long-Term Corporate Bond Index Monthly
Average Corporates plus 3 percent. Payment of deferred amounts generally
commences at retirement. In October 2004, Occidental adopted a new 2005 Deferred
Compensation Plan to comply with the requirements of the 2004 American Jobs
Creation Act (the "Jobs Creation Act"). This new plan is substantially the same
as the previous plan except for the deletion of certain provisions that are not
in compliance with the Jobs Creation Act. All future compensation deferrals will
be covered by the new plan.

DEFERRED STOCK PROGRAM - The Occidental Petroleum Deferred Stock Program permits
executives to defer the receipt of qualifying stock awards. Deferral elections
are irrevocable and must be made 12 months prior to the completion of the
performance period that relates to performance-based awards. The program also
covers stock awards which provide for mandatory deferral upon vesting. Deferred
share units earn dividend equivalents that may be paid currently in cash or
reinvested as additional deferred share units. Payment of deferred share units
generally commences at retirement. In October 2004, Occidental adopted a new
2005 Deferred Stock Program to comply with the requirements of the Jobs Creation
Act. This new program is substantially the same as the previous program except
for the deletion of certain provisions that are not in compliance with the Jobs
Creation Act. All future stock deferrals will be covered by the new plan.

SUPPLEMENTAL RETIREMENT PLAN - The Occidental Petroleum Corporation Supplemental
Retirement Plan provides additional retirement benefits outside of the
limitations imposed by law on qualified retirement and savings plans. All
employees whose participation in Occidental's qualified retirement and savings
plans are limited by applicable tax laws are eligible to participate in the
Supplemental Retirement Plan. Annual plan contributions for each participant
equal the benefit amounts that would have accrued under the qualified plans, but
for the tax law limitations. Benefits are vested after five years of service.
Due to enactment of the Jobs Creation Act, new contributions to the plan have
been terminated as of December 31, 2004. Occidental anticipates that it will
adopt a new supplemental retirement plan in 2005 that will comply with the
requirements of the Jobs Creation Act. Any future supplemental retirement plan
contributions will be covered by the new plan.

FINANCIAL COUNSELING - Occidental pays for financial counseling services for
selected executive officers. Most executives are given an annual allotment which
they may use for tax return preparation, investment planning, and similar
services. Occidental executives are required to have their personal tax returns
prepared by a tax professional qualified to practice before the Internal Revenue
Service to ensure compliance with applicable tax laws. Any financial counseling
fees that are paid by Occidental are reflected as income for the executive and
are subject to appropriate withholding taxes.

GROUP EXCESS LIABILITY INSURANCE - Selected executives are given the opportunity
to participate in group excess liability insurance coverage. Coverage amounts
vary from $5 million for most participants to $10 million for senior executive
officers. Occidental pays the annual premium for the group coverage and a
pro-rata portion of the premium amount is then added to each executive's income
and is subject to appropriate withholding taxes.


                                       15



CHANGE OF CONTROL ARRANGEMENTS

The 2001 Incentive Compensation Plan has provisions that, in the event of a
change in control of Occidental, require the outstanding awards, including stock
options, granted under such plan to become fully vested and exercisable unless
the Plan Administrator determines prior to the occurrence of the event that
benefits will not accelerate. The 2001 Incentive Compensation Plan was approved
by Occidental's stockholders.

REPORT OF THE EXECUTIVE COMPENSATION AND HUMAN RESOURCES COMMITTEE

THE COMMITTEE AND ITS RESPONSIBILITIES - The Executive Compensation and Human
Resources Committee (the "Committee") administers Occidental's executive
compensation program. In this regard, the Committee (1) sets annual and
long-term goals for the Chairman, President and Chief Executive Officer and
evaluates, in consultation with the Lead Independent Director, the CEO's
performance against those goals to determine the CEO's compensation, (2) reviews
and approves annual compensation and executive benefits for all other executive
officers, (3) administers Occidental's equity-based incentive plans (including
the review and approval of equity-based awards to executive officers), (4)
reviews on a periodic basis the operation of executive compensation
arrangements, including management perquisites, to determine if they are
properly coordinated and reasonably relate to executive performance, and (5)
annually reviews director compensation. The Committee's charter reflects these
various responsibilities.

The Committee's membership is determined by the Board and is composed of five
independent directors who are not eligible to participate in Occidental's
employee plans or programs. The Committee meets at least four times during the
year, and may also consider and take action by written consent. The Committee
meets in executive session, without the presence of management, when it
discusses and determines compensation for the CEO. The Committee Chair reports
on Committee actions and recommendations at Board meetings. Occidental's Human
Resource staff supports the Committee in its work. In addition, the Committee
has access to the services of outside advisors and experts.

In 2004, Committee members completed an assessment regarding the adequacy of the
Committee charter, the composition of the Committee, the attendance and
contributions of Committee members, the content and presentation of Committee
materials, and the Committee's access to relevant information. The assessment
confirmed the Committee members' belief that the Committee charter is
appropriate and that Committee operations effectively implement the duties set
forth in the charter.

EXECUTIVE COMPENSATION PHILOSOPHY - The Committee's guiding philosophy is to
establish an executive compensation program that will attract, motivate, reward
and retain top quality executive leadership that will achieve superior corporate
performance and stockholder value. The Committee bases its compensation
decisions on the following core principles:

     o  Pay is Performance-Based - Occidental's general compensation philosophy
     is that total compensation should vary with Occidental's performance in
     achieving financial and non-financial objectives. Executive base salaries
     at Occidental are targeted at or above the median of salaries at comparable
     companies in the oil industry. Salaries are coupled with incentive programs
     that enable total compensation to rise above industry norms in years when
     Occidental's performance exceeds that of its oil industry peer group.
     Significant portions of executive compensation are at risk and are
     dependent upon performance.

     o  Stock Ownership is Emphasized - The Committee believes that executive
     stock ownership effectively aligns the interests of executives with those
     of stockholders and provides a strong motivation to build stockholder
     value. Occidental has established specific stock ownership objectives for
     key management employees and has designed its long-term incentive awards to
     support executive stock ownership. The Committee also believes that a
     significant portion of each executive's total compensation should be
     dependent on the appreciation of Occidental's common stock.

     o  Compensation Opportunities Must Be Competitive To Attract And Retain
     Talented Employees - The Committee evaluates Occidental's performance and
     actual executive compensation, and compares them with comparable data from
     oil industry companies as well as a broader group of leading industrial
     companies to determine appropriate executive compensation arrangements.

EXECUTIVE COMPENSATION PROGRAM - In administering Occidental's executive
compensation program, the Committee looks at total compensation levels for
Occidental's executives and compares that to total compensation in the
competitive market for comparable positions. The total compensation package for
each executive is broken down into the three basic components of (1) base
salary, (2) annual incentive, and (3) long-term incentives, as discussed in more
detail below. Executive compensation is tied directly to Occidental's
performance and provides a balance between the long-term and short-term
performance of the company. Based on 2004 proxy data which shows compensation
for 2003, the actual total compensation for Occidental's five highest paid
executive officers fell in the top quartile of total compensation paid to
executives in peer companies in the oil industry (Apache Corporation, Devon
Energy Corporation, ExxonMobil Corporation, Kerr-McGee Corporation, Marathon Oil
Corporation and the peer group companies listed on page 20). In 2004, the
Committee also reviewed survey data for a select group of large industrial
companies and confirmed the compensation levels as being appropriate in light of
Occidental's outstanding performance and relative market capitalization compared
to its peer companies and the industrial group over a three-year period ending
in 2003. For other executive officers, the 2004 actual total compensation
generally fell between the median and the upper quartile of total compensation
paid to executives


                                       16



in comparable positions. The Committee determined these compensation levels to
be appropriate considering individual contributions and Occidental's
performance.

     o  Base Salary - The Committee sets base salaries after considering an
     executive's responsibilities, level of experience, overall business
     performance, individual achievements and contributions, and compensation
     for similar positions at peer group companies and/or as displayed in
     relevant survey data for large industrial companies. Base salaries for
     officers are generally targeted to approximate the median of the
     comparative data.

     Executives are eligible for an annual merit increase to base salary based
     primarily on performance of job responsibilities. A merit increase is
     generally delivered as a cash increase to base salary, but other
     compensation vehicles may be employed in lieu of a cash increase. For the
     past four years, Occidental's five highest paid officers have received
     restricted share units in lieu of cash base salary adjustments (with the
     exception of officers who had promotions or scheduled retirements). In
     general, executive officers with the highest level and amount of
     responsibility have the lowest percentage of their total compensation fixed
     as base salary and the highest percentage of their total compensation
     variable and dependent upon Occidental's performance.

     o  Annual Incentive - Occidental provides executives with an annual
     opportunity to earn cash incentive awards under the Executive Incentive
     Compensation Plan (EICP). 60 percent of the award is based on Occidental's
     performance as measured against predetermined financial targets and 40
     percent is based on a subjective assessment of an executive's achievement
     of predetermined individual performance objectives, as well as the
     executive's response to unanticipated challenges during the plan year. For
     Occidental's five highest paid executives and other corporate executives,
     the financial performance measure is earnings per share. For a division
     executive, the financial measures include performance measures such as
     division earnings and cash flow.

     In the first quarter of each year, the Committee establishes for executive
     officers an incentive target expressed as a percentage of base salary. The
     Committee reviews executive compensation information derived from relevant
     survey data for the oil industry and large industrial companies in
     determining appropriate incentive target percentages, which range from the
     median to the upper quartile of the comparative data. Actual incentive
     payments may vary from 0 percent to 200 percent of the incentive target,
     based on company and executive performance, thus directly aligning
     executive pay with Occidental's financial performance. For the 2004
     performance period, the Committee established individual incentive targets
     ranging from 45 percent to 130 percent of base salary. The Committee also
     set the earnings per share targets at $2.50, $3.00, and $3.50 for a 0
     percent, 100 percent, and 200 percent payout, respectively, of the
     financial portion of the incentive opportunity. The 2004 financial results
     yielded an earnings per share of $6.49, resulting in a 200 percent payout
     of the financial portion of the incentive opportunity for the five highest
     paid executives and other corporate officers. Final incentive payments,
     including the subjective portion of the incentive opportunity, ranged from
     165 percent to 200 percent of the target award amounts.

     o  Long-Term Incentives - Occidental grants executives long-term incentive
     awards, which include stock options, stock appreciation rights, performance
     stock, and restricted share units, from its 2001 Incentive Compensation
     Plan. These awards are granted to encourage executives to view Occidental
     from the stockholders' perspective, to create an ongoing incentive for
     executives to increase stockholder value, and to retain executives who
     possess the skills that are crucial to Occidental's success. The awards
     represent a significant portion of the total compensation value provided to
     executive officers. The long-term incentive awards granted to Occidental's
     executives, including the CEO, are compared to long-term incentive awards
     made by other oil companies and large industrial companies to their CEO's
     and other senior executives and reflect Occidental's performance relative
     to such companies.

     o  Stock Options or Stock Appreciation Rights are generally granted
     annually to executives and other managers and key contributors based upon
     their level of responsibility, ability to impact results, and individual
     performance. Executive officers receive both stock options and stock
     appreciation rights. Options and stock appreciation rights are granted with
     an exercise price equal to the market price of Occidental's common stock on
     the date of grant, generally vest over a period of three years, and expire
     after ten years. These options and stock appreciation rights only have
     value to the recipients if the price of Occidental's stock appreciates
     after the options or stock appreciation rights are granted.

     In 2004, Occidental granted 758,000 stock appreciation rights and 758,000
     stock options to executive officers.

     o  Performance Stock Awards are granted annually to a select group of
     executives, including executive officers. The awards usually cover a
     four-year performance period. Executives are granted target share unit
     awards that equal a specified percentage of the executive's base salary.
     For corporate executives, the payment of the target share unit awards is
     dependent upon Occidental's total stockholder return over the performance
     period compared to the total stockholder return for a group of comparison
     companies. For division executives, the payment of the target share unit
     awards is dependent upon Occidental's comparative total stockholder return
     and upon the division's return on assets compared to the return on assets
     goal established for the division at the beginning of the performance
     period. Payment amounts, which are paid in actual shares of Occidental
     common stock, may vary from 0 percent to 200 percent of the targeted share
     unit award amounts, depending upon Occidental's performance.


                                       17



     In 2004, executive officers received performance stock awards for the
     performance period 2004 through 2007. Targeted share unit awards ranged
     from 45 percent to 150 percent of base salary. Comparison companies
     included Amerada Hess, Anadarko, Burlington Resources, ChevronTexaco,
     ConocoPhillips, Kerr-McGee, and Unocal. A total of 114,103 share units were
     granted as target awards.

     In 2005, the Compensation Committee certified the payment of the
     performance stock award granted for the performance period commencing
     January 1, 2001. The performance period closed on December 31, 2004, and
     the Committee determined that Occidental's total stockholder return for the
     period ranked second compared to the total stockholder return for each
     company in the award comparison group. Award payments ranged from 83.5
     percent to 183.5 percent of target awards. A total of 310,660 shares of
     Occidental's common stock was certified as payable to executive officers.

     o  Restricted Share Units are awarded to executive officers. The awards
     support Occidental's compensation strategy of placing more pay at risk for
     senior executives and emphasizing the linkage of pay and performance. As
     previously noted, over the past four years, Occidental's five highest paid
     executives (with the exception of retiring executives and executives who
     have been promoted) have received restricted share unit awards in lieu of
     base salary increases. For the five highest paid executives, the awards
     vest over three-to-five year restriction periods and, upon vesting, are
     mandatorily deferred into the Occidental Deferred Stock Program until
     retirement. For the other executive officers, the awards vest over a
     three-year restriction period and, upon vesting, some of the awards may be
     mandatorily deferred until after retirement.

     In 2004, Occidental granted 663,000 restricted share units to executive
     officers.

     The Committee has recommended to the Board of Directors that a new 2005
     Long-Term Incentive Plan be submitted for stockholder approval. This plan,
     included in Exhibit B and described on page 23 of this Proxy Statement,
     will provide a basis for future stock awards, which are designed to
     attract, retain and motivate Occidental's executives and employees. If the
     new plan is approved by stockholders, no future awards will be granted from
     the current plan, however, stock options and other stock awards granted
     prior to the adoption of the new plan will continue to be governed by the
     current plan.

EXECUTIVE COMPENSATION PROGRAM PRACTICES

     o  Deductibility Of Executive Compensation - Section 162(m) of the U.S.
     Internal Revenue Code of 1986, as amended, places a limit of $1,000,000 on
     the amount of compensation that Occidental may deduct in any one year with
     respect to each of its five most highly paid executive officers. Certain
     performance-based compensation elements approved by stockholders, such as
     stock options, stock appreciation rights, and performance stock awards, are
     not subject to the deduction limit. Although tax consequences are
     considered in its compensation decisions, the Committee has not adopted a
     policy that all compensation must be deductible, rather the Committee gives
     priority to other objectives when it deems appropriate.

     o  Employment Agreements - Occidental offers employment agreements to key
     executives only when it is in the best interest of Occidental and its
     stockholders to attract and retain such key executives and to ensure the
     continuity and stability of management. In accordance with a policy adopted
     by the Board of Directors in September 1992, no employment agreements with
     new executives will contain provisions, commonly referred to as "golden
     parachutes," that provide for additional severance benefits in the event of
     a change of control. For a summary of the employment agreements for four of
     the five named executive officers, see "Employment Agreements" at page 13.

     o  Stock Ownership Guidelines - Because the Committee believes in linking
     the interests of management and stockholders, the Committee approved stock
     ownership guidelines for Occidental's senior management in 1996. The
     Committee reviewed and updated the guidelines in February 2005. Executive
     officers are expected to comply with the guidelines within four years of
     the later of the effective date of the guidelines or the date of their
     appointment as an executive officer. Stock ownership is defined as stock
     owned by the officer directly or through Occidental's Savings Plan, awarded
     under certain long-term incentive arrangements, such as restricted share
     unit or performance stock awards, or deferred under one of Occidental's
     deferred stock programs. Under the current guidelines, the ownership
     targets are ten times salary for the Chairman, President and Chief
     Executive Officer, five times salary for the other named executive
     officers, three times salary for Executive Vice Presidents and two times
     salary for Vice Presidents. The Committee determined that, as of December
     31, 2004, all executive officers were in compliance with the guidelines.

EXECUTIVE BENEFITS - In addition to the executive compensation program outlined
above, Occidental also provides executive officers with a number of executive
benefits. The primary executive benefits include deferred compensation and
deferred stock plans and the Supplemental Retirement Plan (see page 15 for a
summary of the principal terms of such plans). In addition, on a selective basis
and depending upon circumstances, some executives also have availability to
annual medical examinations, tax preparation and financial counseling, club
memberships, group excess liability coverage, lunch service and the use of
corporate aircraft (subject to reimbursement to the Company for any personal
use) (see the Summary Compensation Table at page 10).


                                       18



COMPANY PERFORMANCE AND COMPENSATION FOR THE CHAIRMAN, PRESIDENT AND CHIEF
EXECUTIVE OFFICER - Under Dr. Irani's leadership, Occidental has executed an
aggressive restructuring to create large, efficient oil and gas assets in core
geographies, improve the cash contribution of the chemical business, and
significantly strengthen the balance sheet. Over the five-year period from
December 31, 1999 to December 31, 2004, Occidental's total debt has decreased
almost 28 percent while oil and gas production has increased 33 percent. During
this same period, the value of Occidental's Common Stock has appreciated by
$13.5 billion, and Occidental has paid dividends to stockholders equal to $1.9
billion, for a total increase in stockholder value of $15.4 billion. As a direct
result of these actions, Occidental's total return to stockholders exceeded that
of its peer group for this time period. See Performance Graph on page 20.

The Committee looks at several factors in determining Dr. Irani's compensation,
including Dr. Irani's leadership and vision in developing successful business
strategies for Occidental in a competitive marketplace. Each year, the Committee
approves primary performance goals for Dr. Irani. For 2004, the goals included
(1) the enhancement of the value of Occidental's portfolio of assets, (2)
improvement in the quality and consistency of earnings, (3) strengthening the
balance sheet, and (4) improving the quality of Occidental's management.
Compensation decisions are arrived at by the Committee during executive
sessions, in consultation with the Lead Independent Director, without the
presence of the Chairman, President and Chief Executive Officer, and
subsequently discussed with the Board of Directors.

The 2004 compensation for Dr. Irani consisted of base salary, an annual cash
incentive, and long-term incentives. The Committee considered each of these
components individually and in aggregate, compared to relevant proxy and survey
data, to determine appropriate compensation adjustments and incentives. With
respect to base salary, the Committee granted Dr. Irani a restricted share unit
award in December 2004 in the amount of 80,000 share units in lieu of a 2005
merit increase to his base salary. The award is mandatorily deferred until after
retirement under the 2005 Deferred Stock Program.

The Committee acknowledged Dr. Irani's significant accomplishments with respect
to his 2004 performance goals and his contributions to Occidental's success in
2004 by awarding him a cash incentive award of $3,380,000 for 2004. Dr. Irani
elected to defer this bonus under the 2005 Deferred Compensation Plan.

During 2004, the Committee granted Dr. Irani several long-term incentive awards.
Effective January 2004, the Committee granted to Dr. Irani a target performance
stock award in the amount of 46,165 share units. The actual payment of this
award, which may vary from 0 percent to 200 percent of target, will be based on
the Company's total stockholder return compared to a group of peer companies
during a four-year performance period. In July 2004, Dr. Irani received a stock
option grant in the amount of 350,000 shares, a stock appreciation grant in the
amount of 350,000 shares, and a restricted share unit grant in the amount of
250,000 share units. The payment of the restricted share unit grant is
mandatorily deferred until after retirement under the 2005 Deferred Stock
Program.

Dr. Irani also earned a payout from his 2001 performance stock award, in the
amount of 125,377 shares of Occidental common stock, based on Occidental's total
stockholder return, for the period 2001 through 2004, compared to the total
stockholder return for the peer companies designated in 2001. Since Occidental
ranked second compared to the designated peer companies, Dr. Irani's target
award was paid out at 167 percent of his target award, per the terms of the
award. Dr. Irani elected to defer the receipt of this award until after
retirement under the 2005 Deferred Stock Program.

CONCLUSION - The Committee is satisfied that the compensation provided to
executives at Occidental is structured to foster a performance-oriented culture
and to create a strong alignment with the long-term best interests of Occidental
and its stockholders and that compensation levels are reasonable in light of
performance and industry practices.

PERFORMANCE GRAPH

The following graph compares the yearly percentage change in the cumulative
total return of the common stock with the cumulative total return of the
Standard & Poor's 500 Stock Index and with that of the peer group over the
five-year period ending on December 31, 2004. The graph assumes that $100 was
invested in Occidental common stock, in the stock of the companies in the
Standard & Poor's 500 Index and in an equal-weighted portfolio of the peer group
companies at the beginning of the period (December 31, 1999) and that all
dividends received within a quarter were reinvested in that quarter. The peer
group companies are Amerada Hess Corporation, Anadarko Petroleum Corporation,
Burlington Resources, Inc., ChevronTexaco Corporation, ConocoPhillips,
Kerr-McGee Corporation, Occidental and Unocal Corporation.

PROPOSAL 2: RATIFICATION OF INDEPENDENT AUDITORS
--------------------------------------------------------------------------------

AUDIT AND OTHER FEES

AUDIT AND NON-AUDIT SERVICES PRE-APPROVAL POLICY AND PROCEDURES - The Audit
Committee must give prior approval to any management request for any amount or
type of service (audit, audit-related and tax services or, to the extent
permitted by law, non-audit services) Occidental's independent auditor provides
to Occidental. Additionally, the Audit Committee has delegated to the Committee
Chair and Vice Chair full authority to approve any such request provided the
Audit Committee Chair presents any approval so given to the Audit Committee at
its next scheduled meeting. All audit, audit-related and tax services rendered
by KPMG in 2004 were approved by the Audit Committee or the Audit Committee
Chair before KPMG was engaged for such services. No services of any kind were
approved pursuant to a waiver permitted pursuant to 17 CFR 210.2-01(c)(7)(i)(C).

AUDIT FEES - The aggregate audit fees incurred for professional services
rendered by KPMG LLP for the years ended December 31, 2004 and December 31,
2003, were $9,088,000 and $5,629,000, respectively. This amount includes fees
necessary to perform an audit or quarterly review in accordance with Generally
Accepted Auditing Standards and services that generally only the independent
auditor can reasonably provide, such as comfort letters, statutory audits,
attest services, consents and assistance with, and review of, documents filed
with the Securities and Exchange Commission. The 2004 amount includes
approximately $3,100,000 of fees related to KPMG's attestation of Occidental's
internal controls over financial reporting as of December 31, 2004.

AUDIT RELATED FEES - Fees of $642,0000 and $1,026,000 were incurred for
professional services rendered by KPMG LLP for the years ended December 31, 2004
and December 31, 2003, respectively, for assurance and related services that are
traditionally performed by the independent auditor. More specifically, these
services include, among others: employee benefit plan audits, accounting
assistance in connection with proposed or consummated transactions and
consultation concerning financial accounting and reporting standards.

TAX FEES - Fees of $50,000 and $47,000 were incurred for tax services rendered
by KPMG LLP for the years ended December 31, 2004 and December 31, 2003. More
specifically, these services include, among others, tax consultation related to
proposed or consummated transactions and general tax consultation.

ALL OTHER FEES - For the years ended December 31, 2004 and December 31, 2003, no
fees were incurred for services rendered by KPMG LLP, other than the services
described under "Audit Fees," "Audit Related Fees" and "Tax Fees".

REPORT OF THE AUDIT COMMITTEE

The Audit Committee has reviewed and discussed Occidental's audited financial
statements for the fiscal year ended December 31, 2004, including management's
annual assessment of and report on Occidental's internal control over financial
reporting, with management and KPMG LLP. In addition, the Audit Committee has
discussed with KPMG LLP, Occidental's independent auditors, the matters required
to be discussed by Statement on Auditing Standards No. 61, Communication with
Audit Committees, as amended and as currently in effect. The Audit Committee
received from KPMG LLP written disclosures and the letter regarding its
independence as required by Independence Standards Board Standard No. 1,
Independence Discussions with Audit Committees, as amended and as currently in
effect. The Audit Committee has also considered whether the provision of
non-audit services provided by KPMG LLP to Occidental is compatible with
maintaining their independence and has discussed with KPMG LLP the firm's
independence.

Based upon the reports and discussions described in this report, the Audit
Committee recommended to the Board that the audited financial statements be
included in Occidental's Annual Report on Form 10-K for the year ended December
31, 2004, to be filed with the Securities and Exchange Commission.

                              Respectfully submitted,

                              THE AUDIT COMMITTEE

                              Aziz D. Syriani (Chair)
                              Rosemary Tomich (Vice Chair)
                              R. Chad Dreier
                              John E. Feick
                              Irvin W. Maloney


                                       21



RATIFICATION OF SELECTION OF INDEPENDENT AUDITORS

The Audit Committee of the Board of Directors of Occidental has selected KPMG
LLP as independent auditors to audit the consolidated financial statements of
Occidental and its subsidiaries for the year ending December 31, 2005. KPMG LLP
has audited Occidental's financial statements since 2002. A member of that firm
will be present at the annual meeting, will have an opportunity to make a
statement, if so desired, and will be available to respond to appropriate
questions.

A majority of the shares of common stock represented at the meeting and entitled
to vote must vote FOR this proposal to ratify the selection of auditors. If the
stockholders do not ratify the selection of KPMG LLP, the Audit Committee will
appoint the independent auditors for 2005, which may be KPMG LLP. If KPMG should
decline to act or otherwise become incapable of acting or if its employment is
discontinued, the Audit Committee will appoint the independent auditors for
2005.

THE BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE FOR THE PROPOSAL TO RATIFY THE
SELECTION OF KPMG LLP AS INDEPENDENT AUDITORS FOR 2005. YOUR PROXY WILL BE SO
VOTED UNLESS YOU SPECIFY OTHERWISE.


PROPOSAL 3: ADOPTION OF 2005 LONG-TERM INCENTIVE PLAN
--------------------------------------------------------------------------------

APPROVAL OF ADOPTION OF 2005 LONG-TERM INCENTIVE PLAN

The Board of Directors of the Company believes that Occidental's long-standing
policy of encouraging stock ownership by its employees and non-employee
directors through stock-based awards has been a significant factor in the
success of the Company. The Board believes that the Occidental Petroleum
Corporation's 2005 Long-Term Incentive Plan (the "2005 Plan") will be an
important part of that policy by providing incentives to employees and
non-employee directors based on the attainment of corporate objectives or
increases in stockholder value. On February 10, 2005, the Board adopted the 2005
Plan, subject to the receipt of stockholder approval at the Annual Meeting.

The purposes of the 2005 Plan are to enable the Company to attract and retain
top quality employees and non-employee directors and to provide them with an
incentive to enhance stockholder return. Under the Company's 2001 Incentive
Compensation Plan (the "2001 Plan"), Occidental has been authorized to issue
27,000,000 shares of Common Stock in the form of stock options, stock units,
restricted stock, stock bonuses, stock appreciation rights, performance-based
awards and dividend equivalents, as well as other awards. As a result of prior
grants under the 2001 Plan, the number of shares currently available for such
grants has been reduced to approximately 1,900,000, after allowance for shares
issuable as dividend equivalent on deferred awards and approximately 3,500,000
shares being held with respect to an equivalent number of outstanding
cash-settled stock appreciation rights pending the resolution of the treatment
of such stock appreciation rights under the 2004 American Jobs Creation Act (the
"Jobs Creation Act"). The Board of Directors has determined that this number is
insufficient to provide the Company with an adequate incentive device, and
therefore has adopted and proposes that the stockholders approve the 2005 Plan.
If the 2005 Plan is approved, no additional awards will be granted under the
2001 Plan. However, 9,862,657 shares will remain reserved for issuance of shares
in connection with outstanding awards (including the possibility of stock
settlement of the cash-settled stock appreciation rights referred to above) and
satisfaction of dividend equivalents on deferred awards.

Under the 1996 Restricted Stock Plan for Non-Employee Directors (the "1996
Plan"), Occidental has been authorized to issue 250,000 shares of Common Stock
in the form of restricted stock. The 1996 Plan terminates pursuant to its terms
on April 26, 2006. As a result, the grants to directors following the 2005
Annual Meeting will be the last award that may be made under the 1996 Plan. The
Board of Directors believes that it is in the best interest of the stockholders
to continue to provide equity-based compensation to non-employee directors. If
the 2005 Plan is approved, no additional grants will be made under the 1996 Plan
other than the award payable on the first business day following the 2005 Annual
Meeting, which will aggregate 29,900 shares.

If the stockholders approve the 2005 Plan, it will be effective on May 6, 2005
or, if later, the date on which it is approved and will continue for 10 years
unless terminated sooner. The principal features of the 2005 Plan are summarized
below. The following summary is qualified in its entirety by the full text of
the 2005 Plan, a copy of which is attached as Exhibit B to this Proxy Statement.
Capitalized terms used in the summary are used as defined in the 2005 Plan.

VOTING INFORMATION

A majority of the shares represented at the meeting and entitled to vote at the
meeting, must vote FOR this proposal to approve the 2005 Plan. Your broker may
vote your shares on this matter only if you give voting instructions. Broker
non-votes will be disregarded and have the same effect as votes against the
proposal.

If the proposal is approved, 17,000,000 shares will be registered under the
Securities Act of 1933, as amended, and will be available for issuance under the
2005 Plan. If the 2005 Plan is not approved at the Annual Meeting, awards will
be made under the 2001 Plan only to the extent there are shares available for
issuance and under the 1996 Plan only to the extent awards are permitted to be
made before the 1996 Plan terminates.


                                       22



THE BOARD OF DIRECTORS HAS APPROVED AND RECOMMENDS THAT YOU VOTE FOR THE
APPROVAL OF THE 2005 PLAN. YOUR PROXY WILL BE SO VOTED UNLESS YOU SPECIFY
OTHERWISE.

SUMMARY DESCRIPTION OF THE 2005 PLAN

AWARDS - The 2005 Plan authorizes stock options, stock units, restricted stock,
phantom stock, stock bonuses, stock appreciation rights, stock purchase rights,
Performance-Based Awards, dividend equivalents, dividend rights, Common Shares,
as well as other awards (described in Section 5 of the 2005 Plan) responsive to
changing developments in management and director compensation. In addition, the
2005 Plan authorizes cash awards, which may be instead of, in addition to or as
part of another award. The 2005 Plan provides the flexibility to offer
competitive incentives and to tailor benefits to specific needs and
circumstances. Grants may be made on an immediate or a deferred basis, singly,
or in tandem or combination with other grants, or in substitution for other
grants. Generally, an option or stock appreciation right will expire, or other
award will vest, not more than 10 years after the date of grant.

SHARES AVAILABLE - Under the 2005 Plan, the aggregate share limit is seventeen
million (17,000,000) Common Shares, but any Common Shares issued in connection
with awards other than options or stock appreciation rights will be counted
against this limit as three Common Shares for every one Common Share issued in
connection with such award. No individual may be granted options, stock
appreciation rights or other awards in any 36-month period covering more than
four million (4,000,000) Common Shares.

To prevent dilution or expansion of participants' rights, the number and kind of
shares available under the 2005 Plan and then outstanding stock-based awards, as
well as exercise or purchase prices, Performance Goals and share limits are
subject to adjustment or awards may be exchanged for cash payments or other
awards, in the event of certain reorganizations, mergers, combinations,
consolidations, recapitalizations, reclassifications, stock splits, stock
dividends, asset sales or other similar events, or extraordinary dividends or
distributions of property to stockholders.

If an award is forfeited, cancelled, does not vest or is paid in cash, or if
Common Shares are subject to awards that expire or for any reason are
terminated, cancelled, or fail to vest, then any unissued Common Shares
allocated to such award will again be available for subsequent awards under the
2005 Plan. Common Shares subject to options or stock appreciation rights that
are exercised will not be available for subsequent awards and the following
transactions involving Common Shares will not result in additional shares
becoming available for subsequent awards under this 2005 Plan: (a) Common Shares
tendered in payment of an option; (b) Common Shares withheld for taxes; and (c)
Common Shares repurchased by the Company using option proceeds.

The Common Stock is traded on the New York Stock Exchange, and on March 3, 2005,
the per share closing price was $73.01. Occidental intends to register the
shares issuable under the 2005 Plan under the Securities Act of 1933 after it
receives stockholder approval.

ELIGIBILITY - Any officers or employees of the Company or any of its
subsidiaries and any non-employee directors of the Company are eligible to
receive awards under the 2005 Plan. As of December 31, 2004, Occidental had
approximately 7,200 employees (nine of whom were executive officers) and 10
non-employee directors.

ADMINISTRATION - The 2005 Plan will generally be administered by The Executive
Compensation and Human Resources Committee of the Board (the "Administrator").
The Administrator consists of at least two directors of the Company, each of
whom is a "disinterested person" within the meaning of Rule 16b-3 under the
Exchange Act and an "outside director" within the meaning of Section 162(m) of
the Internal Revenue Code of 1986, as amended (the "Code"). The Board, however,
may delegate certain functions to different committees so long as each committee
granting awards under the 2005 Plan consists exclusively of Board members.

The Administrator determines who is eligible to receive awards, the number of
shares that are to be subject to awards and the terms and conditions of such
awards, including, subject to certain restrictions, the price (if any) to be
paid for the shares or the award. Subject to the other provisions of the 2005
Plan, the Administrator has the authority (a) to permit the recipient of any
award to pay the purchase price of Common Shares or the award in cash, the
delivery of previously owned Common Shares, a reduction in the number of Common
Shares or other property otherwise issuable to the participant, a cashless
exercise, or the cancellation of indebtedness or conversion of other securities;
(b) to accelerate the receipt or vesting of benefits pursuant to an award; and
(c) to make certain adjustments to an outstanding award and authorize the
conversion, succession or substitution of an award, in each case, pursuant to
Sections 4.2 of the 2005 Plan.

STOCK OPTIONS - An option is the right to purchase Common Shares at a future
date at a specified price (the "Option Price"). The Option Price per share may
be no less than the Fair Market Value of a share on the date of grant. An option
may either be an incentive stock option or a nonqualified stock option.
Incentive stock options may not be granted to non-employee directors, and are
taxed differently from nonqualified stock options, as described under "Federal
Income Tax Consequences" below. Incentive stock options are also subject to more
restrictive terms and are limited in amount by the Code. Full payment for shares
purchased on the exercise of any option must be made at the time of such
exercise in a manner approved by the Administrator.


                                       23



STOCK APPRECIATION RIGHTS - A stock appreciation right is the right to receive
payment of an amount equal to the excess of the Fair Market Value of a Common
Share on the date of exercise of the stock appreciation right over the base
price of the stock appreciation right. The base price will be established by the
Administrator at the time of grant of the stock appreciation right, but will not
be less than the Fair Market Value of a share on the date of grant. Stock
appreciation rights may be granted independently or in connection with other
awards.

RESTRICTED STOCK AWARDS - Typically, a restricted stock award is an award for a
fixed number of Common Shares subject to restrictions. The Administrator
specifies the price, if any, the participant must pay for such shares and the
restrictions (which may include, for example, continued service) imposed on such
shares. Restricted stock may not vest over a period of less than three years.

PERFORMANCE-BASED AWARDS - Performance-Based Awards are awards whose grant,
vesting, exercisability or payment depends upon the satisfaction of any one or
more Performance Goals. Performance-Based Awards may be stock-based (payable in
stock only or in cash or stock) or may be cash-only awards. The performance
period may range from one to five years.

Section 162(m) Awards are a type of Performance-Based Award designed to satisfy
the requirements for deductibility under Section 162(m) of the Code. These
awards are earned and payable only if a participant reaches specific
preestablished Performance Goals approved by the Administrator in advance of
applicable deadlines under the Code and while the performance relating to the
Performance Goals remains substantially uncertain. The specific Performance
Goals are preestablished targeted levels of any one or more Performance
Objectives, and Performance Objectives may be one or more of the following
business criteria: A/R day sales outstanding, A/R to sales, debt, debt to debt
plus stockholder equity, debt to EBIT or EBITDA, EBIT, EBITDA, EPS, EVA, expense
reduction, interest coverage, inventory to sales, inventory turns, net income,
operating cash flow, pre-tax margin, return on assets, return on capital
employed, return on equity, sales, stock price appreciation, and total
stockholder return (TSR), each as defined further in Appendix A to the 2005
Plan.

Performance Goals or other features of a Section 162(m) Award may be (a)
adjusted to reflect a change in corporate capitalization, a corporate
transaction (such as a reorganization, combination, separation, merger,
acquisition, or any combination of the foregoing) or a complete or partial
corporate liquidation, or (b) calculated either without regard for or to reflect
any change in accounting policies or practices affecting the Company and/or the
Performance Objectives or Performance Goals, or (c) adjusted for any other
circumstances or event, or (d) any combination of (a) through (c), but only to
the extent in each case that such adjustment or determination in respect of
Section 162(m) Awards would be consistent with the requirements of Section
162(m) to qualify as performance-based compensation.

Upon a change in the business or operations of the Company or other events or
circumstances, the Administrator may modify the terms of a Performance-Based
Award or adjust a Performance Goal; provided however that in the case of Section
162(m) Awards any such modification or adjustment may not violate the
limitations imposed by Section 162(m).

STOCK BONUSES - The Administrator may grant a stock bonus to any eligible person
to reward exceptional or special services, contributions or achievements in the
manner and on such terms and conditions (including any restrictions on such
shares) as determined from time to time by the Administrator. The number of
shares so awarded will be determined by the Administrator and may be granted
independently or in lieu of a cash bonus.

STOCK UNITS - Stock units represent a fictitious share of Company stock and are
generally credited to a recordkeeping account. Typically, the value of a stock
unit is based upon the value of an actual share of Company stock.

DIVIDEND EQUIVALENTS; DIVIDEND RIGHTS - Dividend rights or equivalents are
amounts payable in cash or stock (or additional stock units that may be paid in
stock or cash) equal to the amount of dividends that would have been paid on
shares had the shares been outstanding from the date the stock-based award was
granted.

SETTLEMENTS - The Administrator may permit payment of awards under the 2005 Plan
in the form of cash, Common Stock or any combination thereof.

TRANSFER RESTRICTIONS - Subject to exceptions contained in Section 5.6 of the
2005 Plan or as otherwise permitted by law or in the applicable award agreement,
awards under the 2005 Plan are not transferable by the recipient other than by
will or the laws of descent and distribution and are generally exercisable,
during the recipient's lifetime, only by him or her. Any amounts payable or
shares issuable pursuant to an award will be paid only to the recipient or the
recipient's beneficiary or representative.

CHANGE OF CONTROL - Unless before a Change in Control the Administrator
determines that, upon its occurrence, benefits will not be accelerated, then
generally upon the Change in Control, each option and stock appreciation right
will become immediately exercisable, restricted stock will vest, cash and
Performance-Based Awards and stock units will become payable and any other
rights of a participant under any other award will be accelerated to give the
participant the benefit intended under any such award. A Change in Control Event
under the 2005 Plan generally includes a 20 percent or more change in ownership,
certain changes in a majority of the Board, certain mergers or consolidations,
sale of substantially all of the Company's assets or stockholder approval of a
liquidation of the Company.

AMENDMENTS; PLAN TERMINATION - The Board may amend or terminate the 2005 Plan.
However, no amendment or termination may impair the rights of a participant
under an outstanding award in any material way without such participant's


                                       24



consent. Stockholder approval is required for any Plan amendment that would (a)
materially increase the benefits accruing to participants; (b) materially
increase the number of securities which may be issued; or (c) materially modify
the requirements as to eligibility for participation. Additionally, the exercise
price of stock options and stock appreciation rights may not be reduced without
stockholder approval.

FEDERAL INCOME TAX CONSEQUENCES - The following is a brief summary of some of
the federal income tax consequences of common transactions under the 2005 Plan
based on federal income tax laws in effect on January 1, 2005. This summary is
not intended to be exhaustive and, among other considerations, does not describe
state, local or international tax consequences. In addition, the following does
not address the recently enacted American Jobs Creation Act of 2004, which added
legislation concerning deferred compensation and may require amendments to the
2005 Plan to comply with this legislation. Further, until future guidance is
issued by the Internal Revenue Service, it is unclear how this legislation will
change the tax consequences described below.

With respect to nonqualified stock options, the Company is generally entitled to
deduct (and the optionee recognizes taxable income in) an amount equal to the
difference between the option exercise price and the fair market value of the
shares at the time of exercise. With respect to incentive stock options, the
Company is generally not entitled to a deduction nor does the participant
recognize income at the time of exercise, however, the difference between the
option exercise price and the fair market value of the shares at the time of
exercise will be an item of tax preference for determination of the alternative
minimum tax. The current federal income tax consequences of other awards
authorized under the 2005 Plan generally follow basic patterns: stock
appreciation rights are taxed and deductible in substantially the same manner as
nonqualified stock options; nontransferable restricted stock subject to a
substantial risk of forfeiture results in income recognition equal to the excess
of the fair market value over the price paid (if any) only at the time the
restrictions lapse (unless the recipient elects to accelerate recognition as of
the date of grant); bonuses, Performance-Based Awards and dividend rights or
equivalents are generally subject to tax at the time of payment; and cash-based
awards are generally subject to tax at the time of payment. In each of the
foregoing cases, the Company will generally have a corresponding deduction at
the time the participant recognizes income.

If an award is accelerated under the 2005 Plan in connection with a change in
control (as this term is used under the Code), the Company may not be permitted
to deduct the portion of the compensation attributable to the acceleration
("parachute payments") if it exceeds threshold limits under the Code (and
certain related excise taxes may be triggered). Furthermore, if the compensation
attributable to awards is not "performance-based" within the meaning of Section
162(m) of the Code, the Company may not be permitted to deduct the aggregate
nonperformance-based compensation in excess of $1,000,000 in some circumstances.

SPECIFIC BENEFITS - The number, amount and type of awards to be received by or
allocated to eligible persons under the 2005 Plan in the future cannot be
determined at this time. The Company expects that future grants to officers and
employees will not be substantially different from those granted under the 2001
Plan, which are described in the Compensation Tables beginning at page 10 and
that future grants to non-employee directors will not be substantially different
from those granted under the 1996 Plan. For information regarding options,
restricted stock awards and performance stock awards granted to executive
officers of the Company under the 2001 Plan, see the material under "Executive
Compensation" beginning at page 10 and for information of restricted stock
awards granted to non-employee directors under the 1996 Plan, see the material
under "Compensation of Directors" on page 7.

SECURITIES AUTHORIZED FOR ISSUANCE UNDER EQUITY COMPENSATION PLANS

Occidental has two equity compensation plans for its employees pursuant to which
options, rights or warrants have or may be granted: the 1995 Incentive Stock
Plan, the 2001 Plan, and one equity plan for non-employee directors: the 1996
Stock Plan. Each of the Plans was approved by Occidental's stockholders.
Occidental has no other equity compensation plans pursuant to which options,
rights or warrants could be granted.

The following is a summary of the shares reserved for issuance as of December
31, 2004 pursuant to outstanding options, rights or warrants granted under
Occidental's equity compensation plans. The summary does not include the
17,000,000 shares which would be available under the proposed 2005 Plan.

          available for issuance.


STOCKHOLDER PROPOSALS
--------------------------------------------------------------------------------

GENERAL INFORMATION

Occidental has been advised by two holders of common stock of their intention to
introduce at the annual meeting the proposals described below. The Board of
Directors disclaims any responsibility for the content of the proposals and for
the statements made in support thereof which, except for any reference to the
proposal number, are presented in the form received from the stockholders.

VOTE REQUIRED TO APPROVE

A majority of the shares of common stock represented at the meeting and entitled
to vote must vote FOR to approve a stockholder proposal. Abstentions and broker
nonvotes have the same effect as votes AGAINST a proposal.

VOTING RESULTS

The results of the vote will be published on Occidental's web site within 14
calendar days following the meeting, in Occidental's Quarterly Report on Form
10-Q for the quarter ended June 30, 2005, and in the Report on the Annual
Meeting, all of which may be accessed through www.oxy.com.

LEGAL EFFECT OF APPROVAL

Each of the stockholder proposals set forth below is a request to the Board of
Directors to consider a matter. If the proposal passes, the Board of Directors
may consider, in its business judgment, whether to take the requested action or
not, but it is not legally obligated to do so.


                                       26



BOARD ACTION WITH RESPECT TO APPROVED PROPOSALS

It has been the practice of Occidental's Board of Directors to consider matters
that are approved by the stockholders and, if appropriate, to refer the matter
to the appropriate Board committee for further study and recommendation to the
full Board. Generally, this initial consideration and referral takes place at
the next regularly scheduled meeting of the Board. Depending on the complexity
of the issue and the desire of the committee to seek advice from independent
advisors, the committee usually reports to the full Board no later than the
final meeting of the calendar year, which is usually held in early December. The
final action taken by the Board with respect to the proposal and, if applicable
a timetable for implementation of the Board action, will be posted on
Occidental's web site.

STOCKHOLDER RIGHT TO ENFORCE A PROPOSAL

As explained above, generally stockholder proposals are requests to the Board to
consider a matter. If a proposal that is approved requests that the Board take,
or refrain from taking, some action and the Board does not do so, then the
stockholder may submit the same proposal for consideration at the next Annual
Meeting, by following the procedures described on page 29. In the alternative, a
stockholder may challenge the Board's business judgment not to implement the
proposal by commencing litigation in the Chancery Court of the State of
Delaware, Occidental's state of incorporation. Delaware law contains certain
procedural requirements that must be followed before a suit may be commenced,
including a requirement that, unless it would otherwise be futile, a demand be
made on Occidental identifying the alleged wrongdoers, the wrongdoing allegedly
perpetrated and the resultant injury to Occidental and the legal action the
stockholder wants the Board to take on Occidental's behalf.


PROPOSAL 4: STOCKHOLDER STATEMENT OPPOSING BOARD-SPONSORED PROPOSALS
--------------------------------------------------------------------------------

Mr. Carl Olson, P.O. Box 6102, Woodland Hills, California 91365, the owner of
110 shares of Common Stock, has notified Occidental that he intends to present
the following proposal at the 2005 Annual Meeting:

                                    PROPOSAL

     Be it resolved by the stockowners to request the Board to amend the bylaws
as follows:

     1. Every proposal that the board of directors sponsors for a vote by the
stockowners shall be accompanied in the proxy statement by opposing statements
by at least two stockowners.

     2. The board shall take measures as it deems necessary to obtain such
opposing statements from competent and informed stockowners.

     3. The length allowed for all the stockowner opposing statements together
for each board-sponsored proposal shall be the same number of words used in the
board-sponsored proposal, but in no case less than 500 words.

                              SUPPORTING STATEMENT

     When we stockowners vote on proposals, we should be able to read pro and
con presentations. Unfortunately at Occidental Petroleum, for all the proposals
that the board sponsors there are no opposing statements allowed by the board in
the proxy statement. This policy is a disservice to the stockowners and should
be replaced by a policy of having opposing statements from at least two
stockowners. We should hear what "the rest of the story" might be for each
board-sponsored proposal.

     Your vote YES now could result in your being better informed in voting in
the future. And that can result in guiding Oxy toward a better future.

THE BOARD OF DIRECTORS' STATEMENT IN OPPOSITION

THE BOARD OF DIRECTORS BELIEVES THAT THIS PROPOSAL IS UNNECESSARY AND WOULD BE
IMPRACTICAL TO IMPLEMENT. Any stockholder seeking guidance on proxy voting could
easily find independent analysis on any proposal to be voted on at the Company's
Annual Meeting. Large institutional investors, who employ professional
independent analysts, often make their voting decisions available before a
company's annual meeting. For example, a stockholder can easily visit the web
site of the California Public Employees Retirement System to find out how it
will vote on matters, and why.

The proposal is more than unnecessary, however; it would also be impractical, if
not impossible. In order to implement the proposal, Occidental would have to (a)
determine which stockholders were "competent and informed" in any area in which
the Board wishes to sponsor a proposal; (b) solicit statements of opposition
from such stockholders; and (c) ensure that statements of opposition are the
prescribed length. Moreover, the Board does not know if Occidental could solicit
such statements of opposition in advance of the proxy statement without
violating the Securities and Exchange Commission's proxy rules.

Even if Occidental could determine which stockholders were competent and
informed, and could determine which of those competent and informed stockholders
opposed the proposal, the Company cannot force any of its stockholders to
provide a


                                       27



statement of the length that would be required. In addition, the proposal does
not contain a provision for the Company to verify that the statements are
truthful, which may result in the inclusion of false statements, which are
against SEC rules.

Finally, the Board sees no way that this solicitation could be done without
incurring significant expenses - both from the mass mailing to stockholders to
the verification of the background of any stockholder who wishes to write a
statement in opposition.

The Board believes that this proposal would saddle the Company with a huge
burden in cost and labor when there is better, professional, independent
analysis available through reputable sources such as large institutional
investors.

ACCORDINGLY, THE BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE AGAINST THE
FOREGOING STOCKHOLDER PROPOSAL. YOUR PROXY WILL BE SO VOTED UNLESS YOU SPECIFY
OTHERWISE ON THE PROXY CARD.


PROPOSAL 5: VOTE REGARDING FUTURE GOLDEN PARACHUTES
--------------------------------------------------------------------------------

Mr. Emil Rossi, P.O. Box 249, Boonville, California 95415, the owner of 415
shares of Common Stock, has notified Occidental that he intends to present the
following proposal at the 2005 Annual Meeting:

                                    PROPOSAL
               5 -- Allow Vote regarding Future Golden Parachutes

     RESOLVED: Allow Vote regarding Future Golden Parachutes. Shareholders
request that our Board seek shareholder approval for future golden parachutes
for senior executives. This applies to benefits exceeding 2.99% of the sum of
the executive's base salary plus bonus. Future golden parachutes include
agreements renewing, modifying or extending existing severance agreements or
employment agreements with golden parachute or severance provisions.

     This includes that golden parachutes are not given for a change in control
or merger which is approved but is not completed. Or for executives who transfer
to a successor company. This proposal would include to the fullest extent each
golden parachute that our Board has or will have the power to grant or modify
Our company would have the flexibility of seeking approval after tentative
agreement on golden parachutes.

51% Yes-Vote

     The 26 shareholder proposals voted on this topic achieved an impressive 51%
average yes-vote in 2004.

Progress Begins with a First Step

     I believe that the need to take the above one RESOLVED step is reinforced
because our overall governance fitness is not impeccable. For instance in 2004
it was reported:

     o  Occidental Director John Chalsty was designated a "problem director" by
        The Corporate Library (TCL), an independent investment research firm in
        Portland, Maine. Reason: Mr. Chalsty is chairperson of the committee
        that sets executive compensation at Occidental, which received a CEO
        Compensation grade of "F" by TCL.

     o  Occidental Director Rosemary Tomich was designated a "problem director"
        because she was the chairperson of the committee that set executive
        compensation at Occidental, which received a CEO Compensation rating of
        "F" by TCL.

     o  TCL's ratings for our company were:

        OVERALL RATING = D
        Overall Board Effectiveness -- A
        Board Composition -- D
        CEO Compensation -- F

     o  Our Lead Director had 21 years director tenure -- independence concern.

     o  Our key Audit Committee had two members with more than 21-years tenure
        each -- independence concern.

     o  Our Directors were still allowed a $25,000 annual matching gift plan --
        independence concern.

     o  Five directors were allowed to hold from 4 to 9 director seats each -
        over-extension concern.

     o  Five directors were CEOs elsewhere -- CEO to fellow CEO-bias concern.

     o  2003 CEO pay of $38 million including stock option grants.

     Source: http://www.aflcio.org/corporateamerica/paywatch/ceou/database.cfm
     Plus $94 million in unexercised stock options from previous years.

     o  If CEO pay is excessive - this could be a sign that our board is weak in
        its oversight of our CEO.

     o  Occidental is the subject of "Pay for performance? You must be joking.",
        July 22, 2004 edition of Board Briefs by TCL.


                                       28



     The existence of the above governance concerns arguably heightens the
importance of passing the one RESOLVED topic of this proposal.

     Institutional investors such as the California Public Employees Retirement
System recommended shareholder approval of golden parachutes in their proxy
voting guidelines.

                  Allow Vote regarding Future Golden Parachutes

                                    YES ON 5

THE BOARD OF DIRECTORS' STATEMENT IN OPPOSITION

THE BOARD OF DIRECTORS HAS ALREADY IMPLEMENTED THE RESOLUTION. In September
1992, the Board of Directors adopted a policy that "no future employment
agreements containing `golden parachute' provisions shall be entered into
between this Corporation and any of its executive officers." A statement to this
effect has been in the Company's proxy statement each year since 1993.

Stock plans, such as Occidental's 2001 Incentive Compensation Plan and the
proposed 2005 Long-Term Incentive Plan, which have change of control provisions,
are submitted to the stockholders for approval. While change of control
provisions exist in the Company's Deferred Compensation Plan and Deferred Stock
Program, these plans cover amounts that an employee has already earned but
elected to defer, and do not provide for payment of additional sums in the event
of a change of control. In addition, distributions from the deferral plans must
comply with Section 409A of the Internal Revenue Code and, in the case of key
employees, may not occur until six months after termination.

Occidental's early adoption of good corporate practices, such as its policy on
golden parachutes, has earned Occidental consistently excellent government
ratings from the credible, independent organizations that issue such ratings.
GovernanceMetrics International has twice given Occidental its highest overall
rating of 10, most recently in January 2005 and, as of November 2004,
Institutional Shareholder Services indicated that Occidental outperformed 92.6
percent of the companies in the S&P 500 and 98.1 percent of the companies in the
Energy group. Moody's Investor Services noted that Occidental "generally follows
recommended best practices. This predates Sarbanes-Oxley and is the result of
steady improvement over the past 12 years."

ACCORDINGLY, THE BOARD OF DIRECTORS RECOMMENDS A VOTE AGAINST THE FOREGOING
STOCKHOLDER PROPOSAL. PROXIES SOLICITED BY THE BOARD OF DIRECTORS WILL BE SO
VOTED UNLESS STOCKHOLDERS SPECIFY OTHERWISE IN THE PROXY CARD.


STOCKHOLDER PROPOSALS FOR THE 2006 ANNUAL MEETING OF STOCKHOLDERS
--------------------------------------------------------------------------------

Stockholders interested in submitting a proposal for inclusion in the proxy
statement and proxy card relating to the 2006 Annual Meeting of Stockholders may
do so by following the procedures in Rule 14a-8 under the Securities Exchange
Act of 1934. To be eligible for inclusion, stockholder proposals must be
addressed to Occidental's Secretary at 10889 Wilshire Boulevard, Los Angeles,
California 90024, and be received no later than November 15, 2005.

Under Occidental's By-laws, stockholders must follow certain procedures to
introduce an item of business at an annual meeting that is not included in the
proxy materials. These procedures provide that an item of business to be
introduced at an annual meeting must be submitted in writing to the Secretary at
10889 Wilshire Boulevard, Los Angeles, California 90024. Notice of the proposed
item of business must be received no later than February 25, 2006, and must
include the information required by Occidental's By-laws.

In either case, the stockholder submitting the proposal or a representative of
the stockholder must present the proposal in person at the meeting.

The chairman of the meeting may refuse to allow the transaction of any item of
business not presented in compliance with Occidental's By-laws. In addition, the
proxies solicited on behalf of the Board of Directors will have discretionary
authority to vote against any such item of business.


                                       29



NOMINATIONS FOR DIRECTORS FOR TERM EXPIRING IN 2007
--------------------------------------------------------------------------------

NOMINATING COMMITTEE POLICY

It is the policy of the Nominating and Corporate Governance Committee to
consider nominees recommended by stockholders if the stockholder complies with
the procedures outlined below. In prior years, the Nominating Committee has
identified candidates through recommendations from other nonmanagement
directors, executive officers, including the Chief Executive Officer and other
third parties. The Nominating Committee anticipates that, if a vacancy on the
Board were to occur for the term expiring in 2007, it would use these sources as
well as stockholder recommendations to identify candidates.

In deciding if a candidate recommended by a stockholder or identified by another
source is qualified to be a nominee, it is the Nominating Committee's policy to
consider:

     o  Whether the candidate is independent as defined in Occidental's
     Corporate Governance Policies and as applied with respect to Occidental and
     the stockholder recommending the nominee, if applicable;

     o  Whether the candidate has the business experience, character, judgment,
     acumen and time to commit in order to make an ongoing positive contribution
     to the Board;

     o  Whether the candidate would contribute to the Board achieving a diverse
     and broadly inclusive membership; and

     o  Whether the candidate has the specialized knowledge or expertise, such
     as financial or audit experience, necessary to satisfy membership
     requirements for committees where specialized knowledge or expertise may be
     desirable.

If there is a vacancy and the Nominating Committee believes that a recommended
candidate has good potential for Board service, the Nominating Committee will
arrange an interview with the candidate. Pursuant to its Charter, the Nominating
Committee will not recommend any candidate to the Board who is not interviewed
by the Nominating Committee.

PROCEDURE TO RECOMMEND CANDIDATES

Stockholder recommendations must be received by the Corporate Secretary of
Occidental between September 1 and November 30 of the year preceding the
meeting. Each recommendation must include the following information:

1.  as to each person whom the stockholder proposes for election or reelection
as a director:

     o  the name, age, business address and residence address of the person;

     o  the principal occupation or employment of the person;

     o  the class or series and number of shares of capital stock of Occidental
     which are owned beneficially or of record by the person; and

     o  any other information relating to the person that is required to be
     disclosed in solicitations for proxies for election of directors pursuant
     to the Rules and Regulations of the Securities and Exchange Commission.

2.  as to the stockholder making the recommendation:

     o  the name and record address of such stockholder; and

     o  the class or series and number of shares of capital stock of Occidental
     which are beneficially owned by the stockholder.

The stockholder's recommendation must include the recommended person's written
consent to being named as a nominee and to serving as a director if elected.

PROCEDURE TO NOMINATE CANDIDATES

Under Occidental's By-laws, stockholders may nominate a person to the Board by
complying with the advance notice procedures of the By-laws and attending the
annual meeting to make the necessary motion. The notice must be received between
September 1 and November 30 of the year preceding the meeting and include the
information required by the By-laws.


                                       30

EXHIBIT A: CORPORATE GOVERNANCE POLICIES AND OTHER GOVERNANCE MEASURES
--------------------------------------------------------------------------------

Over the past several years, the Board of Directors has adopted and put into
effect a number of important corporate governance policies described below. The
Board of Directors and the management of Occidental believe that good corporate
governance enhances stockholder value. Occidental's corporate governance
policies, principles and guidelines are intended to improve the performance of
Occidental by taking advantage of the collective skills and experience of
Occidental's directors and officers.

BOARD STRUCTURE AND OPERATION

SIZE OF THE BOARD - In determining the size of the Board, the Board of Directors
will consider the level of work required from each director, including the
requirement that certain Committees be composed entirely of independent
directors.

DIRECTOR CRITERIA - Independent directors (as defined below) will comprise at
least two-thirds of the members of the Board.

INDEPENDENT DIRECTOR - In order for a director to qualify as an "independent
director," the Board must affirmatively determine that the director has no
material relationship with Occidental (either as a partner, stockholder or
officer of an organization that has a relationship with Occidental) that would
preclude that nominee from being an independent director. For the purpose of
such determination, an "independent director" is a director who:

     o  Has not been employed by Occidental within the last five years;

     o  Has not been an employee or affiliate of any present or former internal
     or external auditor of Occidental within the last three years;

     o  Has not received more than $60,000 in direct compensation from
     Occidental, other than director and committee fees, during the current
     fiscal year or any of the last three completed fiscal years;

     o  Has not been an executive officer or employee of a company that made
     payments to, or received payments from, Occidental for property or services
     in an amount exceeding the greater of $1 million or 2 percent of such other
     company's consolidated gross revenues during the current fiscal year or any
     of the last three completed fiscal years;

     o  Has not been employed by a company of which an executive officer of
     Occidental has been a director within the last three years;

     o  Is not affiliated with a not-for-profit entity that received
     contributions from Occidental exceeding the greater of $1 million or 2
     percent of such charitable organization's consolidated gross revenues
     during the current fiscal year or any of the last three completed fiscal
     years;

     o  Has not had any of the relationships described above with an affiliate
     of Occidental; and

     o  Is not a member of the immediate family of any person described above.
     An "immediate family member" includes a person's spouse, parents, children,
     siblings, mothers and fathers-in-law, sons and daughters-in-law, brothers
     and sisters-in-law and anyone (other than domestic employees) who shares
     such person's home.

TENURE - Each director will be elected for a term of one year.

RETIREMENT - No person 75 or older will be elected a director, unless as to such
person such requirement is unanimously waived by the members of the Nominating
and Corporate Governance Committee and such Committee's action is ratified and
approved by a majority of the disinterested directors on the Board of Directors.

BOARD MEMBERSHIPS - No director of Occidental will hold more than four
"for-profit" corporate directorships (including his or her Occidental
directorship) at any one time.

DIRECTOR STOCK OWNERSHIP - Each director will beneficially own at least 5,000
shares of Occidental's stock within two years of his or her election to the
Board.

DIRECTOR COMPENSATION - Compensation for directors will promote ownership of
Occidental's stock to align the interests of directors and stockholders and the
independence of directors.

EXECUTIVE SESSIONS - The independent directors will hold at least two regularly
scheduled executive sessions each year at which employee directors and other
members of management are not present. The Lead Independent Director will
preside at such executive sessions.

BOARD ADVISORS - The Committees of the Board will have standing authorization
(including funding), on their own decision, to consult with members of
management and to retain legal or other advisors of their choice, which advisors
will report directly to the Committee that retained them.


                                      A-1



LEAD INDEPENDENT DIRECTOR - The Board will designate a Lead Independent Director
to coordinate the activities of the independent directors and, in addition, to
perform the following duties:

     o  Advise the Chairman as to an appropriate schedule of Board meetings and
     the receipt of information from management;

     o  Provide the Chairman with input on agendas for the Board and Committee
     meetings;

     o  Recommend to the Chairman the retention of consultants who report
     directly to the Board;

     o  Assist in assuring compliance with the corporate governance policies and
     recommend revisions to the policies;

     o  Coordinate, develop the agenda for and moderate executive sessions of
     the independent directors;

     o  Evaluate, along with the members of the Executive Compensation and Human
     Resources Committee and the full Board, the CEO's performance; and

     o  Recommend to the Chairman the membership of the various Board
     Committees.

MEMBERSHIP OF COMMITTEES - The Nominating and Corporate Governance Committee,
the Executive Compensation and Human Resources Committee and the Audit Committee
will be composed entirely of independent directors and will also satisfy all
applicable membership requirements for such.

COMMITTEE CHARTERS - The Nominating and Corporate Governance Committee, the
Executive Compensation and Human Resources Committee and the Audit Committee
will each have a written charter that addresses the committee's purpose, duties,
responsibilities and annual performance evaluation. The committee charters will
be available through the Internet at www.oxy.com.

BOARD DIVERSITY - The Board is committed to achieving a diverse and broadly
inclusive membership by creating equal opportunity for men and women of every
race, color, religion, ethnicity, national origin and cultural background.

MEETINGS - The Board will hold at least six regularly scheduled meetings each
year.

DIRECTOR ORIENTATION AND EDUCATION - Each new director will be provided with
materials and information concerning Occidental in order to enable the director
to perform the duties of a director. In addition, the Board will provide or
sponsor each year eight hours of continuing education designed to enhance the
performance of individual directors and the Board of Directors.

DIRECTOR RESPONSIBILITIES - Each director will use his or her best efforts to
attend, in person or by telephone, all meetings of the Board and the committees
to which such director is appointed. Each director is responsible for being
familiar with Occidental's Governance Principles, the provisions of the Code of
Business Conduct applicable to directors and the charter of each committee on
which such director serves and for reviewing materials provided in advance of
Board and committee meetings.

PERFORMANCE CRITERIA - The Board will establish performance criteria for itself
and, annually, will evaluate each director, committee and the overall Board.
Board evaluation will include an assessment of, among other things, whether the
Board and its committees are functioning effectively and have the necessary
diversity of skills, backgrounds and experiences to meet Occidental's needs.

     legally valid means (which may result, among other changes, in a greater or
     lesser number of shares subject to the award, a shorter or longer vesting
     or exercise period, or, except as provided below, an exercise or purchase
     price that is higher or lower than the original or prior award), in each
     case subject to Sections 3 and 8.2; provided, however, that in no case
     (other than an adjustment contemplated by Section 7.2) shall the exercise
     price of any option or stock appreciation right be reduced by an amendment
     to the award or a cancellation and re-grant of the award to effect a
     repricing of the award to a price below the Fair Market Value of the


                                      B-3


     underlying Shares on the grant date of the original option or stock
     appreciation right unless specific stockholder consent is obtained;

     (d)  authorize (subject to Sections 7, 8, and 10) the conversion,
     succession or substitution of one or more outstanding awards upon the
     occurrence of an event of the type described in Section 7 or in other
     circumstances or upon the occurrence of other events as deemed appropriate
     by the Committee; and

     (e)  determine the value of and acquire or otherwise settle awards upon
     termination of employment, upon such terms as the Committee (subject to
     Sections 7, 8 and 10) deems appropriate.

4.4  BIFURCATION - Notwithstanding anything to the contrary in this Plan, the
provisions of this Plan may at any time be bifurcated by the Board or the
Committee in any manner so that provisions of any award agreement (or this Plan)
intended or required in order to satisfy the applicable requirements of Rule
16b-3, Section 162(m) or other applicable law, to the extent permitted thereby,
are applicable only to persons subject to those provisions and to those awards
to those persons intended to satisfy the requirements of the applicable legal
restriction.

Plan to the contrary, the Board shall have the authority, in its sole and
absolute discretion, to select non-employee Directors to receive awards other
than ISOs under this Plan. The Board shall set the terms of any such awards in
its sole and absolute discretion, and the Board shall be responsible for
administering and construing such awards in substantially the same manner that
the Committee administers and construes awards to other Eligible Persons.

may be granted as Performance-Based Awards.

     5.2.1 SECTION 162(m) AWARDS. The Committee has discretion to determine if
     any Performance-Based Award is intended to be a Section 162(m) Award. The
     specific Performance Goals in respect of Section 162(m) Awards, other than
     Qualifying Options, must be approved by the Committee in advance of any
     applicable deadlines under Section 162(m) and while the performance
     relating to those goals remains substantially uncertain within the meaning
     thereof. The persons eligible for Section 162(m) Awards shall be executive
     officers of the Company and its subsidiaries and, in the discretion of the
     Committee, other employees of the Company or its subsidiaries who are
     designated by the Committee to receive a Section 162(m) Award because they
     may be executive officers of the Company or its subsidiaries by the time
     their awards are exercised, vested or paid. Except as otherwise permitted
     under Section 162(m), before any Section 162(m) Award is paid, the

     terms of the Section 162(m) Award were in fact satisfied.

     5.2.2 RESERVATION OF DISCRETION - The Committee shall have discretion to

     Performance-Based Awards under this Section 5.2.

     foregoing) or a complete or partial corporate liquidation, or (ii)
     calculated either without regard for or to reflect any change in accounting
     policies or practices affecting the Company and/or the Performance
     Objectives or Performance Goals, or (iii) adjusted for any other
     circumstances or event, or (iv) any combination of (i) through (iii), but
     only to the extent in each case that such adjustment or determination in
     respect of Section 162(m) Awards would be consistent with the requirements
     of Section 162(m) to qualify as performance-based compensation.

5.3  CONSIDERATION FOR SHARES - Shares may be issued pursuant to an award for
any lawful consideration as determined by the Committee, including, without
limitation, services rendered by the recipient of such award, but shall not be
issued for less than the minimum lawful consideration. Awards may be payable in
cash, stock or other consideration or any combination thereof, as the Committee
shall designate in or (except as required by Section 5.2) by amendment to the
terms and conditions governing such award.

or this Plan or in the applicable award terms and conditions, a participant will

is prior to such date of delivery.

5.5 OPTION/STOCK APPRECIATION RIGHT PRICING AND TERM LIMITS - The purchase price
per share of the Shares covered by any option or the base price of any stock
appreciation right shall be determined by the Committee at the time of the
grant, but shall not be less than 100 percent of the Fair Market Value of the
Shares on the date of grant. Any option, stock appreciation right, warrant or
similar right shall expire and any other award shall vest not more than 10 years
after the date of grant. An award may be converted or convertible,
notwithstanding the foregoing limits, into or payable in, Shares or another
award that otherwise satisfies the requirements of this Plan.

     planning purposes and on a basis consistent with the Company's lawful issue
     of securities and the incentive purposes of the award and this Plan.
     Notwithstanding the foregoing, awards intended as ISOs or restricted stock
     awards for purposes of the Code shall be subject to any and all additional
     transfer restrictions necessary to preserve their status as ISOs or
     restricted shares, as the case may be, under the Code.

     5.6 shall not apply to:

          (a)  transfers to the Company,

          (b)  the designation of a beneficiary to receive benefits in the event
          of the  participant's death or, if the participant has died, transfers

          a validly designated beneficiary, transfers by will or the laws of
          descent and distribution,

          (c)  transfers pursuant to a domestic relations order (if approved or
         ratified by the Committee), if (in the case of ISOs) permitted by the
          Code,

          (d)  if the participant has suffered a Disability, permitted transfers
          to or exercises on behalf of the holder by his or her legal
          representative, or

          (e)  the authorization by the Committee of "cashless exercise"
          procedures with third parties who finance or who otherwise facilitate
          the exercise of awards consistent with applicable laws and the express
          authorization of the Committee.

5.7  TAX WITHHOLDING - Upon any exercise, vesting, or payment of any award, the
Company shall:

     (a)  require the recipient (or his or her heirs, personal representatives
     or beneficiaries, as the case may be) to pay or provide for  payment of the
     amount of any taxes which the Company or any subsidiary may be required to
     withhold with respect to such transaction; or

     (b)  deduct from any amount payable in cash the amount of any taxes that
     the Company or any subsidiary may be required to withhold with respect to
     such cash amount.


                                      B-5



5.8  POSSIBLE SHARE OFFSET - In any case where a tax is required to be withheld
in connection with the delivery of Shares under this Plan, the Committee may
require or may permit the holder the right to offset, pursuant to such rules and
subject to such conditions as the Committee may establish, the number of shares
to be delivered by (or otherwise reacquire) the appropriate number of shares
valued at their then Fair Market Value, to satisfy the minimum statutory
withholding taxes with respect thereto.

5.9  CASH AWARDS - The Committee shall have the express authority to pay awards
in cash under this Plan, whether in lieu of, in addition to or as part of
another award.

reason, his or her outstanding awards may thereafter be exercised (if at all) to
the extent provided in the agreement evidencing such award, or as otherwise
determined by the Committee.

6.   TERM OF PLAN

No award shall be granted under this Plan after the tenth anniversary of the
Effective Date of this Plan. After that date, this Plan shall continue in effect
as to then outstanding awards. Any then outstanding award may be amended
thereafter in any manner that would have been permitted earlier, except that no
such amendment shall increase the number of Shares subject to, comprising or
referenced in the award or reduce the exercise or base price of an option or
stock appreciation right or permit cash payments in an amount that exceeds the
limits of Section 3 (as adjusted pursuant to Section 7.2).

7.   ADJUSTMENTS; CHANGE IN CONTROL

a Change in Control, the Committee determines that, upon its occurrence,
benefits under any or all awards will not accelerate or determines that only
certain or limited benefits under any or all awards will be accelerated and the
extent to which they will be accelerated, or establishes a different time in

     award.

The Committee may override the limitations on acceleration in this Section 7.1
by express provision in the award agreement and may accord any Eligible Person a
right to refuse any acceleration, whether pursuant to the award agreement or
otherwise, in such circumstances as the Committee may approve. Any acceleration
of awards shall comply with applicable legal and regulatory requirements.
Without limiting the generality of the foregoing, the Committee may deem an
acceleration to occur immediately prior to or up to 30 days before the
applicable event and/or reinstate the original terms of an award if an event
giving rise to an acceleration does not occur.

If any option or other right to acquire Shares under this Plan has been fully
accelerated as required or permitted by this Plan but is not exercised prior to
(i) a dissolution of the Company, or (ii) an event described in this Section 7.1
that the Company does not survive, or (iii) the consummation of an event
described in Section 7.2 involving a Change in Control approved by the Board,
such option or right will terminate, subject to any provision that has been
expressly made by the Committee or the Board through a plan of reorganization
approved by the Board or otherwise for the survival, substitution, assumption,
exchange or other settlement of such option or right.

7.2  ADJUSTMENTS - The following provisions will apply if any extraordinary
dividend or other extraordinary distribution occurs in respect of the Shares
(whether in the form of cash, Shares, other securities, or other property), or
any reclassification, recapitalization, stock split (including a stock split in
the form of a stock dividend), reverse stock split, reorganization, merger,
combination, consolidation, split-up, spin-off, repurchase, or exchange of
Shares or other securities of the Company, or any similar, unusual or
extraordinary corporate transaction (or event in respect of the Shares) or a
sale of substantially all the assets of the Company as an entirety occurs. The
Committee will, in such manner and to such extent (if any) as it deems
appropriate and equitable:

     (a)  proportionately adjust any or all of (i) the number and type of Shares
     (or other securities) that thereafter may be made the subject of awards
     (including the specific maxima and numbers of shares set forth elsewhere in
     this Plan), (ii) the number, amount and type of shares (or other securities
     or property) subject to any or all outstanding awards, (iii) the grant,
     purchase, or exercise price of any or all outstanding awards, (iv) the
     securities, cash or other property


                                      B-6



     deliverable upon exercise of any outstanding awards, or (v) the Performance
     Goals or Performance Objectives appropriate to any outstanding awards, or

     (b)  in the case of an extraordinary dividend or other distribution,
     recapitalization, reclassification, merger, reorganization, consolidation,
     combination, sale of assets, split-up, exchange, or spin-off, make
     provision for a cash payment or for the substitution or exchange of any or
     all outstanding awards or the cash, securities or property deliverable to
     the holder of any or all outstanding awards based upon the distribution or
     consideration payable to holders of the Shares of the Company upon or in
     respect of such event.

In each case, with respect to awards of ISOs, no such adjustment will be made
that would cause this Plan to violate Section 422 or 424 of the Code or any
successor provisions without the written consent of holders materially adversely
affected thereby. In any of such events, the Committee may take such action
sufficiently prior to such event if necessary or deemed appropriate to permit
the participant to realize the benefits intended to be conveyed with respect to
the underlying shares in the same manner as is available to stockholders
generally.

8.   PLAN AMENDMENT AND TERMINATION

8.1  AUTHORITY OF THE BOARD - Subject to Sections 8.2 and 8.3 and New York Stock
Exchange Rules applicable to companies listed on such Exchange, the Board may
amend or terminate this Plan at any time and in any manner.

8.2  RESTRICTIONS - No amendment or termination of this Plan or change in or
affecting any outstanding award shall deprive in any material respect the
holder, without the consent of the holder, of any of his or her rights or
benefits under or with respect to the award. Adjustments contemplated by Section
7 shall not be deemed to constitute a change requiring such consent.

8.3  STOCKHOLDER APPROVAL - Stockholder approval shall be required for any
amendment to this Plan that would:

     (a)  materially increase the benefits accruing to participants under this
     Plan,

     (b)  materially increase the number of securities which may be issued under
     this Plan, or

     (c)  materially modify the requirements as to eligibility for participation
     in this Plan.

9.   LEGAL MATTERS

9.1  COMPLIANCE AND CHOICE OF LAW; SEVERABILITY - This Plan, the granting and
vesting of awards under this Plan and the issuance and delivery of Shares and/or
the payment of money under this Plan or under awards granted hereunder are
subject to compliance with all applicable federal and state laws, rules and
regulations and to such approvals by any listing, regulatory or governmental
authority as may, in the opinion of counsel for the Company, be necessary or
advisable in connection therewith. This Plan, the awards, all documents
evidencing awards and all other related documents shall be governed by, and
construed in accordance with the laws of the state of Delaware. If any provision
shall be held by a court of competent jurisdiction to be invalid and
unenforceable, the remaining provisions of this Plan shall continue in effect.

9.2  NON-EXCLUSIVITY OF PLAN - Nothing in this Plan shall limit or be deemed to
limit the authority of the Board or the Committee to grant awards or authorize
any other compensation, with or without reference to the Shares, under any other
plan or authority.

9.3  NO EMPLOYMENT CONTRACT - Nothing contained in this Plan (or in any other
documents relating to this Plan or to any award) shall confer upon any Eligible
Person or other participant any right to continue in the employ or other service
of the Company or any subsidiary or constitute any contract or agreement of
employment or other service, nor shall interfere in any way with the right of
the Company or any subsidiary to change such person's compensation or other
benefits or to terminate the employment of such person, with or without cause.

10.  MISCELLANEOUS

10.1 UNFUNDED PLAN - Unless otherwise determined by the Committee, this Plan
shall be unfunded and shall not create (or be construed to create) a trust or a
separate fund or funds. This Plan shall not establish any fiduciary relationship
between the Company or any subsidiary and any participant or other person. To
the extent any person holds any rights by virtue of awards granted under this
Plan, such rights shall be no greater than the rights of an unsecured general
creditor of the Company.

10.2 AWARDS NOT COMPENSATION - Unless otherwise determined by the Committee,
settlements of awards received by participants under this Plan shall not be
deemed a part of a participant's regular, recurring compensation for purposes of
calculating payments or benefits from any Company benefit plan, severance
program or severance pay law of any country.

10.3 FRACTIONAL SHARES - The Company shall not be required to issue any
fractional Shares pursuant to this Plan. The Committee may provide for the
elimination of fractions or for the settlement thereof in cash.


                                      B-7



10.4 FOREIGN PARTICIPANTS - No award shall be made to a participant who is a
foreign national or who is employed by the Company or any subsidiary outside the
United States of America if such award would violate applicable local law. In
order to facilitate the making of an award, the Committee may provide for such
special terms for awards to participants who are foreign nationals, or who are
employed by the Company or any subsidiary outside of the United States of
America, as the Committee may consider necessary or appropriate to accommodate
differences in local law, tax policy or custom. Moreover, the Committee may
approve such supplements to or amendments to this Plan as it may consider
necessary or appropriate for such purposes unless stockholder approval for any
such change would be required in accordance with the provisions of Section 8.
