   Equistar is one of the largest chemical producers in the world with total
1998 pro forma revenues of $5 billion and $7 billion of assets at the end of
1998. It is the world's second largest, and North America's largest, producer
of ethylene, the world's most widely used petrochemical. Equistar is also the
largest producer of polyethylene and propylene in North America.

   Equistar's petrochemicals segment manufactures and markets olefins,
oxygenated chemicals and aromatics. Equistar's olefins products are ethylene,
propylene and butadiene. Olefins and their co-products are basic building
blocks used to create a wide variety of products. Ethylene is used to produce
polyethylene, ethylene oxide, ethylene dichloride and ethylbenzene. Propylene
is used to produce polypropylene. Equistar's oxygenated chemicals include
ethylene oxide, ethylene glycol, ethanol and methyl tertiary butyl ether.
Oxygenated chemicals have uses ranging from paint to cleaners to polyester
fibers. Equistar's aromatics are benzene and toluene.

   Equistar's polymers segment manufactures and markets polyolefins, including
high-density polyethylene, low-density polyethylene, linear low-density
polyethylene, polypropylene and performance polymers. Polyethylene is used to

   Equistar was formed in December 1997 as a Delaware limited partnership owned
by Lyondell Chemical Company and Millennium Chemicals Inc. Lyondell contributed
substantially all of the assets of its petrochemicals and polymers business
segments. Millennium contributed substantially all of the assets of Millennium
Petrochemicals, polyethylene and related products, performance polymers and
ethyl alcohol businesses. In May 1998, Lyondell, Millennium, Equistar and
Occidental Petroleum Corporation consummated a series of transactions to expand
Equistar through the addition of Occidental petrochemical assets. Lyondell's
aggregate interest in Equistar is 41%. Millennium's aggregate interest in

                             About Equistar Funding

   Equistar Funding, a wholly owned subsidiary of Equistar, is a Delaware
corporation formed for the sole purpose of facilitating the financing
activities of Equistar. The outstanding notes were co-issued by Equistar and
Equistar Funding. Equistar and Equistar Funding are also co-issuers of the new
notes. Some institutional investors that might otherwise be limited in their
ability to invest in securities issued by a limited partnership, due to legal
investment laws of their State of organization or their charter documents, may
be able to invest in the notes because Equistar Funding is a co-obligor.

                              . will rank senior to any future subordinated
                                indebtedness

                              We may not incur additional debt that is senior
                              to the notes; however, the new notes will
                              effectively be subordinated to any secured debt
                              that we may incur to the extent of the collateral
                              for the secured debt; currently we have no
                              secured debt.

Restrictive Covenants.......  The outstanding notes have been and the new notes
                              will be issued under an indenture containing
                              restrictive covenants for your benefit. These
                              covenants restrict our ability to

                              . incur indebtedness secured by liens

                              . engage in sale and leaseback transactions

                              . sell all or substantially all of our assets or
                                merge with another entity

                                       5

Form of New Notes...........  The new notes will be represented by one or more
                              permanent global securities deposited with The
                              Depository Trust Company. You will not receive
                              certificates for your new notes unless one of the
                              events described under the heading "Book Entry;
                              Delivery and Form--Certificated Notes" on page
                              109 occurs. Instead, beneficial ownership
                              interests in the new notes will be shown on, and
                              transfers of beneficial ownership will be
                              effected only through, book-entry records
                              maintained by The Depository Trust Company.

                                  Risk Factors

   You should carefully consider the risks below before participating in the
exchange offers.

Risk Factors Relating to the New Notes and the Exchange Offers

If you fail to exchange your outstanding notes, the existing transfer
restrictions will remain in effect; the market value of your outstanding notes
may be adversely affected because of a smaller float.

   If you do not exchange your outstanding notes for new notes under the
exchange offers, then you will continue to be subject to the existing transfer
restrictions on the outstanding notes. In general, the outstanding notes may
not be offered or sold unless they are registered or exempt from registration
under the Securities Act of 1933 and from applicable state securities laws.
Except as required by the exchange and registration rights agreement, we do not
intend to register resales of the outstanding notes.

   The tender of outstanding notes under the exchange offers will reduce the
aggregate principal amount of the notes outstanding. This may have an adverse
effect upon, and increase the volatility of, the market price of any
outstanding notes that you continue to hold due to a reduction in liquidity.

There is no public market for the new notes, and we do not intend to list them
on any securities exchange or automated quotation system; an active trading
market for the notes may not develop.

   There is no existing public market for the new notes. We cannot provide any
assurance about

  . the liquidity of any markets that may develop for the new notes

  . your ability to sell your new notes

  . the prices at which you will be able to sell your new notes

   Future trading prices of the new notes will depend on many factors,
including prevailing interest rates, our operating results, ratings of the new
notes and the market for similar securities. Chase Securities Inc. and Banc of
America Securities LLC, who were the joint book running managers for the
offering of the outstanding notes, have advised us that they currently intend
to make a market in the new notes after completion of the exchange offers.
However, they do not have any obligation to do so, and they may discontinue any
market-making activities at any time without any notice.

   We do not intend to apply for listing of the new notes on any securities
exchange or for quotation of the new notes in any automated dealer quotation
system.

None of the partners of Equistar or their affiliates will have any liability
for payments of principal or interest on the new notes, and you will have no
right to recover against them.

   Our ability to make payments on the new notes is solely dependent upon
Equistar's ability to generate sufficient cash from operations. If Equistar or
Equistar Funding fails to fulfill its obligations under the outstanding notes,
the new notes or the indenture, you will not have the right to recover against
any of Equistar's partners, whether as a general partner or limited partner or
otherwise, or against the partners' respective parents or other affiliates. You
are not a beneficiary of and have no right to enforce any of the arrangements
between Equistar and its partners and their affiliates.

   Equistar Funding is a wholly owned subsidiary of Equistar. The new notes
will be joint and several obligations of Equistar and Equistar Funding.
However, Equistar Funding will have little or no revenues or assets that could
be used to satisfy its obligations under the new notes. As a result, you will
be required as a practical matter to look only to Equistar to satisfy the
obligations under the new notes.

Risk Factors Relating to Equistar's Business

The petrochemical and polymer industries are highly cyclical, and Equistar's
income and cash flows will be affected by external factors beyond our control;
the market value of the new notes may, in turn, be affected by Equistar's
results of operations.

   External factors beyond Equistar's control, such as general economic
conditions, competitor actions, international events and circumstances and
governmental regulation in the United States and abroad, can cause volatility
in the price of raw materials. These external factors can also cause
fluctuations in demand for our products and fluctuations in our prices and
margins. In addition, these external factors can magnify the impact of economic
cycles on our business. As a result, Equistar's income and cash flow will be
affected by industry cycles.

   Equistar and its predecessors' historical operating results reflect the
cyclical and volatile nature of the petrochemical and polymer industries. The
petrochemical and polymer industries are mature, and industry margins are
sensitive to cyclical petrochemical supply and demand balances. The
petrochemical and polymer industries historically experience alternating
periods of tight supply, causing prices and profit margins to increase,
followed by periods when substantial additional capacity is added, resulting in
oversupply and declining prices and profit margins. A number of our products
are highly dependent on durable goods markets, such as housing and automotive,
that are themselves particularly cyclical.

Changes in commodities prices cannot be controlled and will affect Equistar's
income and cash flows; the market value of the new notes may, in turn, be
affected by Equistar's results of operations.

   Due to the commodity nature of most of Equistar's products, we are not
necessarily able to protect our market position by product differentiation or
pass on cost increases to our customers. Accordingly, increases in raw material
and other costs do not necessarily correlate with changes in product prices,
either in the direction of the price change or in magnitude. As a result,
changes in commodity prices will affect Equistar's income and cash flow.

There is overcapacity in the petrochemical and polymer industries, which
results in lower production rates and margins and affects Equistar's income and
cash flows; the market value of the new notes may, in turn, be affected by
Equistar's results of operations.

   Currently, there is overcapacity in the petrochemical and polymer
industries. Moreover, a number of Equistar's competitors in various segments of
the petrochemical and polymer industries have announced plans for expansion of
plant capacity. There can be no assurance that future growth in product demand
will be sufficient to utilize this additional, or even current, capacity.
Excess industry capacity may lower Equistar's production rates and margins and
its income and cash flow.

External factors will cause Equistar's quarter-to-quarter income and cash flows
to vary; the market value of the new notes may, in turn, be affected by
Equistar's results of operations.

   Equistar's quarterly results, including its income and cash flow, may vary
significantly depending on various factors, most of which are out of our
control, including

  . changes in the prices of and demand for our products

  . changes in the cost of raw materials

  . changes in supply arrangements

  . developments in foreign markets

  . unanticipated expenses

  . unscheduled downtime and maintenance

                                       8
<PAGE>

Actions we take will cause Equistar's quarter-to-quarter income and cash flows
to vary; the market value of the new notes may, in turn, be affected by
Equistar's results of operations.

   The actual mix of production rates at our facilities will impact the
comparison of period-to-period results. We commonly take actions that are
intended to yield long-term benefits but may increase the variance of results
from quarter to quarter or even from year to year. For example, Equistar
regularly adjusts the production rate of its facilities to optimize production
costs and margins. Different facilities may have different production rates
from period to period depending on many factors, such as feedstock costs,
transportation costs and supply and demand for the product produced at the
facility during that period. As a result, individual facilities may be operated
below or above their production capacities in any period.

   We will incur costs of any temporary shut-downs of our facilities. Equistar
may idle a facility for an extended period of time because an oversupply of a
particular product and/or a lack of demand for that particular product makes
production uneconomical. These temporary shut-downs could last for several
quarters, and we will incur costs, including the expenses of the shut-down and
restart of these facilities, that may affect quarterly results, including
income and cash flow, when shut-downs and start-ups occur.

Equistar may be active in adding assets or in disposing of assets, which could
affect short-term results of operations; the market value of the new notes may,
in turn, be affected by Equistar's results of operations.

   The purchase or sale of assets may often affect the results of operations of
Equistar, including its income and cash flow, in the short term because of the
costs associated with these transactions. Equistar actively seeks opportunities
to maximize the value of its assets, including combining its assets with those
of third parties to operate more efficiently or create greater value. In many
circumstances, maximizing value will be achieved through the purchase or sale
of assets or through contractual arrangements or joint ventures.

We will require a significant amount of cash to service our indebtedness, and
our ability to generate cash depends on many factors beyond our control; if we
cannot generate sufficient cash, we may not be able to pay our indebtedness,
including principal or interest on the new notes.

   Our ability to make payments on and to refinance our indebtedness, including
the new notes, will depend on our ability to generate cash in the future. Our
ability to fund working capital and planned capital expenditures will also
depend on our ability to generate cash in the future. Several factors beyond
our control will affect our ability to make these payments and refinancings,
including

  . uncertainties associated with the United States and worldwide economies

  . prices of raw materials and products

  . current and potential governmental actions

  . operating interruptions including leaks, explosions, fires, mechanical
    failure, transportation interruptions and spills, releases and other
    environmental risks

   Equistar's $1.25 billion revolving credit facility requires that Equistar
maintain compliance with specified financial ratios and covenants. These
requirements include that the ratio of debt-to-capitalization not exceed 0.6 to
1.0. These requirements also include that we maintain specified levels of an
interest coverage ratio, which varies from period to period. For the period
ended June 30, 1999, the ratio of (a) the sum of operating income and specified
non-cash charges to (b) net interest expense is required to be at least 2.25 to
1.0. A more detailed description of these financial ratios and the other
covenants under the $1.25 billion credit facility, as amended in February 1999,
is described under "Summary Description of Other Indebtedness of Equistar."
Equistar is in compliance with each of the covenants of the $1.25 billion
revolving credit facility as of June 30, 1999. The ability of Equistar to
comply with these ratios and covenants may be affected by events beyond our
control. The failure of Equistar to comply with the required covenants could
permit the lenders to declare all borrowings outstanding under the credit
facility to be due and payable and to terminate some lending obligations. See
"Summary Description of Other Indebtedness of Equistar--$1.25 Billion Revolving
Credit

                                       9

Facility." If this were to occur, Equistar cannot assure you that its assets
would be sufficient to fund a repayment of the indebtedness under the credit
facility. At June 30, 1999, the amount outstanding under the $1.25 billion
revolving credit facility was $750 million.

   We cannot assure you

  . that Equistar's business will generate sufficient cash flow from
    operations

  . that further anticipated cost savings and operating improvements will be
    realized

  . that future borrowings will be available under the $1.25 billion
    revolving credit facility in an amount sufficient to enable us to pay our
    indebtedness, including the new notes, on or before maturity

  . that we will be able to refinance any of our indebtedness on commercially
    reasonable terms, if at all

   With the exception of its $1.25 billion credit facility, Equistar's debt
instruments, including the new notes and the outstanding notes, do not contain
cross-default provisions. However, the Lyondell debt which Equistar assumed in
connection with its formation and on which Lyondell remains contingently liable
(see pages 32 and 111) contains an event of default relating to a bankruptcy,
or an admission in writing of an inability to pay debts when due, of Lyondell
or Equistar. As such, a bankruptcy of Lyondell or Lyondell's admission in
writing of inability to pay its debts would be an event of default under the
assumed debt, of which $563 million remains outstanding as of June 30, 1999. If
one of these events were to occur, all or a portion of the outstanding balance
of $563 million could be accelerated at the option of the holders or a trustee,
and in such case Equistar could be required to use its cash available, or
borrow sufficient cash, or both, to fund a repayment of the amount accelerated.
In addition, because the $563 million could be accelerated in such case, the
lenders under Equistar's $1.25 billion revolving credit facility would have the
right to declare all borrowings outstanding under the credit facility to be due
and payable and to terminate some lending obligations. See "Summary Description
of Other Indebtedness of Equistar--$1.25 Billion Revolving Credit Facility." If
this were to occur, Equistar cannot assure you that its assets would be
sufficient to fund a repayment of all the accelerated indebtedness.

Environmental compliance, cleanup and other requirements can significantly
impact Equistar's operations or cash flow; if the financial impact of
environmental costs or expenditures materially affects Equistar's income, cash
flow or liquidity, the market value of the new notes may be affected.

   Equistar is subject to stringent environmental, health and safety laws and
regulations addressing air emissions, water discharges, generation, handling
and disposal of waste, and other aspects of its operations. Typically, these
laws provide for substantial fines and potential criminal sanctions for
violations. Several of these laws, including the Superfund law, also impose
extensive requirements relating to investigation and cleanup of contamination.
In addition, Equistar may face liability for alleged personal injury or
property damage due to exposure to chemicals at its facilities or chemicals
that it otherwise manufactures, handles or owns.

   Equistar incurs capital and operating costs to comply with environmental,
health and safety laws and regulations. Although we believe Equistar is in
material compliance with environmental, health and safety laws and regulations,
from time to time Equistar receives and addresses notices of violation.
Environmental costs also may arise from changes in laws and regulations and
from identification of additional areas of contamination requiring
investigation or cleanup. We cannot predict with certainty the extent of
Equistar's future liabilities and costs under environmental, health and safety
laws and regulations but expect that it will continue to be significant.

Year 2000 disruptions in operations of Equistar or third parties could
adversely affect Equistar; if the financial impact of Year 2000 disruptions
materially affects Equistar's income or cash flow, the market value of the new
notes may be affected.

   Systems that do not properly recognize and process date-sensitive
information could generate erroneous data, or even fail, as the year 2000
approaches. Equistar is conducting reviews of its key computer systems and

                                       10
<PAGE>

has identified a number of systems that could be affected by the year 2000
issue. Equistar is upgrading these systems to allow them to function properly.
If these steps are not completed successfully in a timely manner, Equistar's
operations and financial performance could be adversely affected through
disruptions in operations.

   Disruptions in the operations of third parties could potentially disrupt
Equistar's operations as well. Equistar relies on services, energy and raw
materials from third parties who may or may not be adversely affected by the
year 2000 issue.

We cannot predict how a change in control of one or more of Lyondell,
Millennium or Occidental, or an exit of any of them, could affect the
operations or business of Equistar.

   Any one or more of Lyondell, Millennium or Occidental may transfer control
of their interests in Equistar or engage in mergers or other business
combination transactions that could result in a change in control of any one
of them. Because of the unanimous approval requirements in Equistar's
partnership governance structure, any transfer of an interest in Equistar or
change of control of a partner would affect the governance of Equistar. We
cannot predict how any such change would affect the operations or business of
Equistar. A direct or indirect transfer of an interest in Equistar generally
may only occur if the other owners are first offered the opportunity to
purchase the interest and the transferee has an "investment grade" debt
rating. However, if interests in Equistar are transferred in a merger or sale
of a majority of the other assets of Lyondell, Millennium or specified
subsidiaries of Occidental, the other owners do not have a right of first
option and the investment grade requirement is not applicable. See
"Description of the Partnership Agreement--Transfers and Pledges of a
Partner's Interest in Equistar" and "Description of the Parent Agreement--
Restrictions on Transfer of Partner Sub Stock.

   Equistar's $1.25 billion revolving credit facility provides that an event
of default occurs if Lyondell, Millennium and Occidental, collectively, cease
to own at least a majority interest in Equistar. An event of default under
Equistar's $1.25 billion revolving credit facility would permit the lenders to
declare amounts outstanding under the credit facility immediately due and
payable and to terminate commitments of the lenders to make revolving loans
and acquire participations in letters of credit or swingline loans. If the
lenders accelerated their loans, Equistar cannot assure you that its assets
would be sufficient to fund a repayment of the indebtedness under the $1.25
billion revolving credit facility.

   Millennium has advised that it is considering the divestiture of its 29.5%
interest in Equistar. Millennium America, an indirect wholly owned subsidiary
of Millennium, provides a limited guarantee under our $1.25 billion revolving
credit facility, which is described under "Summary Description of Other
Indebtedness of Equistar--$1.25 Billion Revolving Credit Facility." If
Millennium were to transfer its interest in Equistar, Millennium America would
be able to terminate its guarantee if Equistar has an investment grade credit
rating or the fair market value of Equistar's assets is at least 140% of the
gross amount of its liabilities. Millennium's successor would not be required
to assume the limited guarantee.

                          Forward-Looking Information

   Some of the statements contained in this prospectus contain forward-looking
statements. These statements include, in particular, statements about our
plans, strategies and prospects under the captions "Prospectus Summary," "Risk
Factors," "Management's Discussion and Analysis of Financial Condition and
Results of Operations" and "Description of Equistar's Business." We use the
terms "estimate," "project," "plan," "intend," "anticipate," "believe,"
"expect," "budget," "forecast," "will," "could," "should" and "may" and similar
expressions to identify forward-looking statements. These statements

  . address activities, events or developments that we expect, believe,
    anticipate or estimate will or may occur in the future

  . are based on assumptions and analyses that we have made and that we
    believe are reasonable

  . are based on various risks and uncertainties, general economic and
    business conditions, business opportunities that may be presented to and
    pursued by us from time to time, changes in laws or regulations and other
    factors, many of which are beyond our control

   Any one of these factors, or a combination of these factors, could
materially affect our future results of operations and the ultimate accuracy of
the forward-looking statements. Although we believe the expectations reflected
in these forward-looking statements are reasonable, they do involve
assumptions, risks and uncertainties, and we cannot assure you that these
expectations will prove to have been correct. These forward-looking statements
are not guarantees of our future performance, and our actual results and future
developments may differ materially from those projected in the forward-looking
statements. See "Risk Factors" beginning on page 8.

   We undertake no obligation to publicly update or revise any forward-looking
statements, whether as a result of new information or otherwise. All oral or
written forward-looking statements attributable to us or persons acting on our
behalf are expressly qualified in their entirety by these cautionary
statements.

                                Use of Proceeds

   We will not receive any cash proceeds from the issuance of the new notes. In
consideration for issuing the new notes, we will receive in exchange a like
principal amount of outstanding notes. The outstanding notes surrendered in
exchange for the new notes will be retired and canceled and cannot be re-
issued. Accordingly, issuance of the new notes will not result in any change in
our capitalization.

   We used the gross proceeds from the sale of the outstanding notes of
approximately $898 million to

  . terminate the outstanding balance under Equistar's $500 million credit
    facility, which was $152 million at termination

  . repay $205 million of capital lease obligations

  . repay $391 million of indebtedness outstanding under the $1.25 billion
    revolving credit facility

  . retire $150 million aggregate principal amount of 10.00% notes upon their
    maturity on June 1, 1999

                Selected Pro Forma and Historical Financial and
                           Operating Data of Equistar

   The table below shows selected pro forma and historical financial and
operating data for Equistar. The selected historical income statement and
balance sheet data

  . as of and for the year ended December 31, 1998

  . as of and for the one month ended December 31, 1997

have been derived from financial statements of Equistar, which have been
audited by PricewaterhouseCoopers LLP, independent accountants.
PricewaterhouseCoopers' report is included elsewhere in this prospectus.
   The selected historical income statement and balance sheet data as of and
for the six months ended June 30, 1999 and 1998 have been derived from the
unaudited financial statements of Equistar. In the opinion of Equistar, the
unaudited financial statements include all material adjustments, consisting of
normal recurring adjustments, necessary to present fairly the information
stated herein. The results of operations for the six months ended June 30, 1999
and 1998 are not necessarily indicative of the operating results for the entire
year. The operating data have been derived from the historical operating
records of Equistar. Neither the historical financial data nor the historical
operating data are necessarily indicative of the future results of operations
of Equistar. The pro forma financial and operating data are not necessarily
indicative of the future results of operations of Equistar.

   The Occidental contributed business was added to Equistar on May 15, 1998.
The actual amounts for the year ended December 31, 1998 include the Occidental
contributed business amounts from May 15, 1998 to December 31, 1998. The
unaudited pro forma financial and operating data for the year ended December
31, 1998 present the results of Equistar as if the Occidental contributed
business had been contributed as of January 1, 1998.

   The unaudited pro forma financial data and operating data for the six months
ended June 30, 1999 present the results of Equistar as if the change in
interest expense resulting from Equistar's use of proceeds from the issuance of
the outstanding notes had occurred as of January 1, 1999. The only pro forma
adjustment for that period is to interest expense, net. See "Equistar Unaudited
Pro Forma Income Statement Data for the Six Months Ended June 30, 1999."

   For purposes of

    Equistar

  . Selected Historical Financial and Operating Data of the Lyondell
    Contributed Business

  . Selected Historical Financial and Operating Data of the Millennium
    Contributed Business

we utilized the definitions and assumptions explained below.

Calculation of EBITDA

   EBITDA is calculated as operating income plus depreciation and amortization
and other income and should not be construed as a substitute for operating
income or a better indicator of liquidity than cash flows from operating
activities, which are determined according to generally accepted accounting
principles. Management included EBITDA to provide additional information with
respect to the ability of Equistar to meet its

  . future debt service

  . capital expenditures

  . working capital requirements

EBIDTA is not necessarily a measure of Equistar's ability to fund its cash
needs. Management believes that investors may find the calculation of EBITDA a
useful tool for measuring our ability to service debt.

Calculation of Ratio of Earnings to Fixed Charges

   For purposes of calculating the ratio of earnings to fixed charges,
earnings represent net income plus fixed charges, excluding capitalized
interest. Fixed charges include

  . interest expense

    plus

  . capitalized interest and that portion of non-capitalized rental expense
    deemed to be the equivalent of interest

Definition of Total Debt

   Total debt is defined as long-term debt, current maturities of long-term
debt and capital lease obligations.

               Equistar Unaudited Pro Forma Income Statement Data
                      For the Year Ended December 31, 1998

   The unaudited pro forma financial data shown below present the financial
results of Equistar for 1998. Occidental contributed assets and liabilities
with a fair value of $2.1 billion to Equistar in exchange for a 29.5% interest
in Equistar in May 1998. However, the financial results of Equistar are
presented below as if both

  . the Occidental contributed business had been contributed as of January 1,
    1998

  . the change in interest expense resulting from Equistar's use of proceeds
    from the issuance of the outstanding notes had occurred as of January 1,
    1998

The numbers under the column captioned "Occidental Contributed Business"
reflect the results of the Occidental contributed business from January 1, 1998
to May 14, 1998, before its addition to Equistar. The unaudited pro forma
financial data do not necessarily reflect the results of operations of Equistar
that would have resulted had these transactions actually been consummated as of
the dates indicated. The data shown below are not necessarily indicative of the
future results of operations of Equistar.

(a) To reflect the additional depreciation expense and goodwill amortization
    for the period from January 1, 1998 to May 14, 1998, related to the
    increase in the fair value in excess of the historical book basis of the
    Occidental contributed business over an average useful life of 25 years.
    Equistar recorded $43 million of goodwill in connection with the purchase
    of the Occidental contributed business.
(b) To reflect the elimination of $38 million of interest expense related to
    debt not contributed to Equistar by Occidental.
(c) To reflect the interest expense of $16 million for the period from January
    1, 1998 to May 14, 1998, related to the additional $700 million of debt
    that was incurred upon consummation of the Occidental contribution using a
    weighted-average interest rate of 6%. The effect of a 1/8% change in
    interest rate would result in an increase or decrease of interest expense
    of approximately $328,000 for the period January 1, 1998 through May 14,
    1998.

in 1998 with a low point of $10.02 per barrel in December 1998 and an annual
average of the month-end prices of $12.94 per barrel. Selected month-end
average prices are as follows: January 1996--$18.39 per barrel, December 1996--
$24.32 per barrel, December 1997--$17.13 per barrel, December 1998--$10.02 per
barrel.]

Second Quarter 1999 Compared to First Quarter 1999

   Equistar reported net income of $41 million for second quarter 1999,
compared to net income of $7 million for first quarter 1999. This increase was
primarily attributable to gains on asset sales in second quarter 1999,
primarily the sale of Equistar's concentrates and compounds business on April
30, 1999. Second quarter was negatively impacted by the effects of outages at
Equistar's two Channelview olefins production units during parts of April and
May 1999. However, when compared to first quarter 1999, the net effect of the
second quarter olefins units outages was comparable to the effects in first
quarter of the scheduled LaPorte plant maintenance turnaround, completed in
first quarter 1999. Overall, margins remained relatively constant quarter to
quarter as higher ethylene and polymers prices, reflecting ongoing tight
supply/demand balances, were offset by higher raw materials costs.

Second Quarter 1999 Compared to Second Quarter 1998 and Year-to-date 1999
Compared to Year-to-date 1998

   Equistar's net income of $41 million for second quarter 1999 decreased from
net income of $44 million for second quarter 1998. This decrease was due to
lower product margins, primarily for polymers products,as polymer sales prices
decreased while polymer raw material costs increased. Petrochemical product
margins also decreased slightly, as petrochemical raw material costs increased
more than petrochemical sales prices. The decrease in petrochemical and
polymers product margins is primarily a result of excess industry capacity that
began in fourth quarter 1997 and continued throughout 1998. The decrease in net
income attributable to lower product margins was offset by gains on asset sales
in second quarter 1999, primarily the sale of Equistar's concentrates and
compounds business. The decrease in net income was also partially offset by
increased sales volumes, primarily as a result of the addition of the
Occidental contributed business in mid-May 1998.

                                       23
<PAGE>

   Equistar's net income of $49 million for the first six months of 1999 was
lower than net income of $165 million for the first six months of 1998. This
decrease was also due to lower petrochemical and polymer product margins, as
average sales prices decreased more than raw material costs due to the excess
industry capacity discussed above. This decrease in net income was also due to
olefins units outages in second quarter 1999, and the scheduled LaPorte, Texas
plant maintenance turnaround. The decrease was partially offset by increased
sales volumes, primarily as a result of the addition of the Occidental
contributed business, and the gains on assets sales in second quarter 1999.

   The following tables reflect selected actual sales volume data and
summarized financial information for Equistar's business segments. The addition
of the Occidental contributed business is reflected prospectively from May 15,
1998.

 Petrochemicals Segment

 Revenues

   Revenues for second quarter 1999 increased 22% compared to second quarter
1998. The increase was due to a 13% increase in sales volumes and higher
average sales prices in second quarter 1999 compared to second quarter 1998.
The increase in sales volumes primarily reflects the addition of the Occidental
contributed

                                       24
<PAGE>

business in mid-May 1998. The increase in average sales prices was due to
higher sales prices for ethylene in second quarter 1999 compared to second
quarter 1998. Sales prices began decreasing in fourth quarter 1997 and
continued their downward trend throughout most of 1998. U.S. market sales
prices increased during the first six months of 1999, due to tighter supplies
and rising raw material costs. As a result, average sales prices for ethylene
for second quarter 1999 were higher than second quarter 1998. However, average
sales prices for ethylene for the first six months of 1999 were slightly lower
than average sales prices for the first six months of 1998.

   Revenues for the first six months of 1999 increased 19% compared to the
first six months of 1998. The increase was due to increased sales volumes,
which increased 23% during the first six months of 1999, primarily as a result
of the addition of the Occidental contributed business in mid-May 1998. The
increase was partially offset by lower average sales prices during the 1999
period. As noted above, average sales prices for the first six months of 1999
were slightly below average sales prices for the first six months of 1998.

 Cost of sales

   Cost of sales for second quarter 1999 increased 22% compared to second
quarter 1998. The increase was primarily a result of higher production levels
as the 1999 period reflected a full quarter of operations of the Occidental
contributed business and higher raw material costs. Cost of sales for the first
six months of 1999 increased 23% as compared to cost of sales for the first six
months of 1998. This increase was due to higher production levels as the 1999
period reflected a full six months of results with the Occidental contributed
business and higher raw material costs.

 Operating Income

   Operating income increased in second quarter 1999 compared to second quarter
1998 primarily due to increased sales volumes. Second quarter 1999 reflected a
full quarter of results with the Occidental contributed business, which was
added in mid-May 1998. This volume benefit was partly offset by lower product
margins as raw material costs increased more than average sales prices. The net
effect of the olefins production unit outages in second quarter 1999 was
substantially offset by the volume effect, in the second quarter 1998, from the
lack of a full quarter of results from the Occidental contributed business.

   Operating income decreased in the first six months of 1999 compared to the
first six months of 1998. The decrease was primarily due to lower product
margins, as feedstock costs increased, the net effect of the olefins production
unit outages in second quarter 1999, and the scheduled LaPorte plant
maintenance turnaround, which was completed in first quarter 1999. These
factors were partly offset by the benefit of increased volumes as a result of
the addition of the Occidental contributed business in mid-May 1998.

Polymers Segment

 Revenues

   Revenues decreased 14% in the second quarter and 16% in the first six months
of 1999 as compared to the comparable 1998 periods as a result of decreases in
industry sales prices. The sales price decreases reflect excess industry
supply, as industry capacity additions exceeded demand growth. The decreases in
sales prices started during the fourth quarter of 1997 and continued in a
downward trend through 1998. Industry prices increased during the first half of
1999, however, average second quarter and first half 1999 sales prices were
lower than the comparable 1998 periods.

 Cost of Sales

   Cost of sales in second quarter 1999 decreased 5% from second quarter 1998.
This decrease was due to decreased production levels as a result of ethylene
supply limitations. The decrease was partially offset by

                                       25
<PAGE>

higher polymer raw material costs, primarily ethylene, in second quarter 1999
compared to second quarter 1998.

   Cost of sales for the first six months of 1999 decreased 7% from the first
six months of 1998. This decrease was also due to decreased production levels
as noted above.

 Operating Income

   Operating income was $9 million for second quarter 1999 compared to $63
million for second quarter 1998. Operating income was $20 million for the first
six months of 1999 as compared to $135 million for the first six months of
1998. The decreases in operating income for the 1999 periods compared to the
comparable 1998 periods are primarily due to lower product margins which
primarily result from lower polymers sales prices.

Interest Expense and Other Income

   Interest expense, net increased from $32 million in second quarter 1998 to
$45 million in second quarter 1999 and from $58 million in the first six months
of 1998 to $84 million in the first six months of 1999. These increases
primarily reflected higher levels of debt due to the addition of the Occidental
contributed business in mid-May 1998 and the issuance of the outstanding notes
in February 1999, which carry a higher fixed interest rate. Other income of $46
million for both second quarter 1999 and the first six months of 1999 primarily
consists of gains on asset sales, including the sale of Equistar's compounds
and concentrates business on April 30, 1999.

Financial Condition

 Operating Activities

   Cash provided by operating activities totaled $169 million in the first six
months of 1999, compared to cash provided by operating activities of $374
million in the first six months of 1998. Cash provided by operating activities
in the 1999 period was primarily generated from income before depreciation
offset by gains on asset sales, and a slight decrease in working capital. Cash
provided by operating activities in the 1998 period primarily related to income
before depreciation and reimbursements from Equistar's owners for payment of
their retained accounts payable balances.

 Investing Activities

   Equistar's capital expenditures were $76 million in the first six months of
1999. The most significant capital expenditures related to the 480-million-
pound HDPE resin expansion project at the Matagorda, Texas facility, which has
a targeted completion in October 1999. Equistar's total 1999 capital budget is
$195 million. Management plans to fund capital expenditures in 1999 from cash
flow from operations.

   In April 1999, Equistar completed the sale of its concentrates and compounds
business, which included the Crockett, Texas and Heath, Ohio facilities, to
Ampacet Corporation. Equistar reported a net gain on the sale of $42 million.

 Financing Activities

   Net cash used in financing activities was $140 million for the first six
months of 1999, including distributions to owners of $125 million. During first
quarter 1999, Equistar completed an offering of outstanding notes in the
principal amount of $900 million. The proceeds were used to refinance $900
million of

                                       26
<PAGE>

existing indebtedness of Equistar during the first six months of 1999. Equistar
also repaid an additional $15 million of indebtedness during this period.

 Liquidity

   As noted above, Equistar completed the offering of the outstanding notes in
the principal amount of $900 million in February 1999. The outstanding notes
consist of $300 million principal amount of 8 1/2% notes due February 2004 and
$600 million principal amount of 8 3/4% notes due February 2009. The proceeds
were used to

  . repay the outstanding balance of $152 million under the $500 million
    credit facility, which was subsequently terminated

  . repay the $205 million of capital lease obligations

  . repay $385 million of indebtedness outstanding under the $1.25 million
    revolving credit facility

  . repay and retire $150 million aggregate principal amount of 10% notes
    upon their June 1, 1999 maturity

For the Year Ended December 31, 1998 Compared to the Year Ended December 31,
1997

Overview

   Income before income taxes was $143 million for the year ended December 31,
1998 compared to $596 million for 1997. The decline in income before income
taxes from 1997 to 1998 was primarily due to lower prices and margins in both
the petrochemicals and polymers segments, which reduced income before taxes by
approximately $776 million. The decline in prices and margins began in fourth
quarter 1997 and continued throughout 1998. The decline was partially offset by
the lower cost of raw materials, which increased income before taxes by $207
million, and increased sales volumes primarily as a result of the addition of
the Occidental contributed business in May 1998, which increased income before
income taxes by $148 million. Occidental contributed assets and liabilities
with a fair value of $2.1 billion to Equistar in exchange for a 29.5% interest
in Equistar. The addition of the Occidental contributed business increased
Equistar's income before taxes for 1998 by approximately $10 million.

   The following tables for the petrochemicals and polymers segments show
selected income statement and operating data. Revenues include intersegment
sales. Cost of sales include intersegment purchases. Total intersegment sales
were $1,158 million for 1998 and $1,512 million for 1997. Total intersegment
purchases were $1,158 million for 1998 and $1,512 million for 1997.
Additionally, Equistar recorded sales to related parties of $545 million during
1998 and $559 million during 1997. All sales are reflected at market price, and
there are no material differences in gross margins between sales to related
parties and sales to third parties.

of Equistar.

 Revenues

   Sales revenues for the petrochemicals segment decreased from $3,866 million
for 1997 to $3,463 million for 1998. The decrease of $403 million was due to
declines in industry sales prices. Sales prices are primarily driven by each of

  . the demand for products as a result of economic conditions in end-use
    markets such as the auto industry, housing construction and consumer
    durable and nondurable goods

                                       28
<PAGE>

  . the operating rate of the installed capacity to produce olefins products

  . the underlying cost of raw materials

   For olefins products, the decrease in sales prices was primarily
attributable to increased industry capacity and downward pressure on sales
prices as a result of the lower cost of raw materials. The decline in sales
prices reduced sales revenue by $1,076 million. This decline was partially
offset by an increase in sales revenue of $673 million due to increased sales
volumes primarily as a result of the addition of the Occidental contributed
business in May 1998.

 Cost of Sales

   Cost of sales decreased from $3,151 million in 1997 to $3,130 million in
1998. The decrease was primarily due to declines in the cost of raw materials,
which were partially offset by slightly higher fixed costs and the addition of
the Occidental contributed business in May 1998.

   Equistar's olefins raw materials tend to follow the cost trends of crude oil
and natural gas. Crude oil prices began dropping in 1997 and continued to fall
throughout 1998, which resulted in lower raw material costs for the
petrochemicals segment. Natural gas prices also dropped in early 1998 and
remained at that level throughout 1998.

 Selling Expenses

   Selling expenses decreased from $31 million in 1997 to $14 million in 1998.
The decrease was primarily due to lower personnel costs as a result of the
consolidation of operations.

 Operating Income

   Operating income decreased from $684 million in 1997 to $319 million in
1998, while gross margin as a percentage of sales decreased from 18% in 1997 to
10% in 1998. The decrease in operating income and gross margin as a percentage
of sales primarily reflected lower product margins as a result of declines in
sales prices and slightly higher fixed costs. The lower product margins
decreased operating income by approximately $720 million. This was partially
offset by an increase in operating income of $207 million due to lower
feedstock costs and an increase of $148 million due to increased sales volumes
primarily as a result of the addition of the Occidental contributed business in
May 1998.

 Revenues

   Sales revenues for the polymers segment decreased from $2,513 million for
1997 to $2,058 million for 1998. The decrease of $455 million is a result of
decreases in industry sales prices. Sales prices are primarily driven by the
following three factors

  . the demand for products as a result of economic conditions in end-use
    markets, such as the auto industry, housing construction and consumer
    durable and nondurable goods

  . the operating rate of the installed capacity to produce polymer products

  . the underlying cost of raw materials

   For polymer products, the sales price decreases were a result of excess
industry supply and lower raw material costs. The excess industry supply and
related sales price decreases began in fourth quarter 1997 and continued
throughout 1998. The sales price decreases reduced sales revenues by
approximately $600 million. This was partially offset by an increase in sales
volumes, which increased sales revenues by $145 million.

 Cost of Sales

   Cost of sales was $1,799 million for 1998 as compared to $2,143 million for
1997. The primary raw materials for the polymers segment are olefins, primarily
ethylene and propylene. During 1998, the industry sales price of ethylene and
propylene decreased steadily, which resulted in lower raw material costs for
the polymers segment. This decrease was partially offset by an increase in
sales volumes.

 Selling Expenses

   Selling expenses were $82 million for 1998 as compared to $137 million for
1997. The decrease of $55 million was primarily due to lower personnel costs as
a result of the consolidation of operations.

 Operating Income

   Operating income decreased from $233 million in 1997 to $177 million in
1998. The decrease of $56 million is a result of lower product margins in 1998.
Polymer sales prices decreased throughout 1998 but were partially offset by
lower raw material costs, resulting in lower margins. The lower product margins
caused gross margin as a percentage of sales to decrease from 15% in 1997 to
13% in 1998.

Restructuring and Other Unusual Charges

   Equistar incurred restructuring charges related to the initial merger and
integration of the businesses contributed by Lyondell and Millennium
Petrochemicals upon the formation of Equistar. Equistar initially recorded $42
million of these costs in December 1997. These charges included approximately
$21 million of severance and other employee-related termination costs related
to a workforce reduction, which were included in other accrued liabilities at
December 31, 1997 and were substantially paid in 1998. The workforce reduction
included approximately 430 employees, primarily in duplicate corporate overhead
functions. All of the 430 employees were terminated in 1998. Additionally,
these charges included employee relocation costs of $6 million and various
other charges of $7 million, all of which were recorded and paid as incurred in
1997. In 1997, the partnership also recorded and paid as incurred transaction
closing costs of $8 million. In 1998, Equistar recorded and paid, as incurred,
an additional $12 million in restructuring charges related to the initial
merger and integration of Equistar. These costs included costs associated with
the consolidation of operations and facilities of $11 million and other
miscellaneous charges of $1 million. The restructuring actions related to the
initial merger and integration were substantially completed in 1998 and there
were no significant changes to Equistar's original estimate of costs that were
accrued as of December 31, 1997. There were no amounts accrued as of December
31, 1998 related to the initial merger and integration of Equistar. The
restructuring charges were not allocated to the business segments.

   Equistar also incurred restructuring charges of $2 million related to the
merger and integration of the Occidental contributed business into Equistar.
These charges were recorded and paid as incurred during 1998. There were no
amounts accrued as of December 31, 1998 related to the merger and integration
of the Occidental contributed business. The restructuring charges were not
allocated to the business segments. The restructuring actions related to the
merger and integration of the Occidental contributed business into Equistar
were substantially completed as of December 31, 1998.

Financial Condition--Equistar

 Operating Activities

   Cash provided by operating activities totaled $846 million for the year
ended December 31, 1998. This was primarily attributable to income before
depreciation and reimbursements from Equistar's owners for payment of their
retained accounts payable balances. This amount also includes $130 million in
proceeds from the sale of accounts receivable primarily related to the
petrochemicals segment. See "--Liquidity and Capital Resources--Accounts
Receivable."

 Investing Activities

   Equistar's capital expenditures were $200 million during the year ended
December 31, 1998. The most significant capital expenditures in 1998 were

  . $56 million for the 480-million-pound HDPE resin expansion project at the
    Matagorda, Texas facility, which has a targeted start-up in third quarter
    1999

  . $22 million for the scheduled maintenance turnaround and expansion of the
    Victoria, Texas facility, which was completed during fourth quarter 1998
    and increased the plant's annual HDPE capacity by approximately 125
    million pounds

 Financing Activities

   Cash used in financing activities during the year ended December 31, 1998
consisted primarily of distributions to owners of $1.4 billion, offset by net
borrowings of $467 million and the repayment of the $345 million note
receivable from Lyondell. The distributions to owners consisted of $495 million
in distributions to Millennium and Occidental in the aggregate, as part of the
addition of the Occidental contributed businesses to Equistar, which were
funded by additional borrowings of long-term debt; $345 million in
distributions to Lyondell and Millennium in the aggregate, related to the
repayment of the note receivable from Lyondell; and $327 million in
distributions to Lyondell and Millennium in the aggregate, for payment of their
retained accounts payable balances. The remaining amount was distributions of
available net operating cash. The borrowings were primarily related to the
acquisition of the Occidental contributed business.

 Liquidity and Capital Resources

   Cash Flows. Equistar's management believes business conditions will be such
that cash balances, cash flow from operations and existing lines of credit will
be adequate to meet near-term and long-term cash requirements for scheduled
debt repayments and to fund ongoing operations. Equistar has a $1.25 billion
revolving credit facility that extends until November 2002, under which $750
million had been borrowed at March 31, 1999. Aggregate maturities of long-term
debt as of June 1, 1999 are

  . 1999 - $-0-

  . 2000 - $42 million

  . 2001 - $90 million

  . 2002 - $866 million

                                       31
<PAGE>

  . 2003 - $29 million

  . thereafter--$1,201 million

   In January 1999, Equistar announced that it was going to temporarily shut
down its gas phase HDPE reactor at Port Arthur, Texas, on March 31, 1999. As a
consequence of the shutdown, Equistar's HDPE production has been reduced by 300
million pounds per year and employment at the unit has been reduced from 200 to
approximately 125. Customers for products at the temporarily shut down unit
will be supplied with comparable products produced at Equistar's Matagorda,
Victoria and LaPorte, Texas, facilities. This transaction is not expected to
have a material impact on Equistar's financial condition, results of operations
or liquidity.

   Capital Expenditures. Equistar's capital expenditures for the one month
ended December 31, 1997 were $12 million. Capital expenditures for the year
ended December 31, 1998 were $200 million. Pro forma capital expenditures in
1998, including the Occidental contributed business, were $222 million.

   Management plans to fund capital expenditures in 1999 from cash flow from
operations. The capital program for 1999 plans for the spending of $195
million, of which $106 million relates to projects which were started before
1999.

   Substantial overhauls, or maintenance turnarounds, are periodically
conducted on production units, typically once every five to seven years. These
maintenance turnarounds are typical for the petroleum and chemical industry and
necessary to maintain, extend and improve the operating capacity and efficiency
rates of the production units. Although maintenance turnarounds on principal
facilities are usually scheduled well in advance, the timing of maintenance
turnarounds may be accelerated or delayed because of unscheduled maintenance
requirements on facilities and as a result of margins and anticipated margins
on products produced at Equistar's facilities. These business decisions to
accelerate or delay do not affect Equistar safety and environmental standards
which govern operation at the facilities at all times. For instance, when
margins are high for Equistar's products, Equistar will be more likely to delay
scheduled maintenance turnarounds to take advantage of higher margins.
Similarly, when margins for Equistar's products are low, Equistar will be more
likely to accelerate scheduled maintenance turnarounds in an attempt to have
the applicable maintenance complete when we anticipate margins will be
improving. Unscheduled downtime and outages are beyond Equistar's control.
Increases and decreases in supply and demand, which affect Equistar's margins,
are also beyond the control of Equistar, although timing of accelerating or
delaying maintenance turnarounds as a result of the supply and demand factors
can be controlled by Equistar.

- --------
(a) Equistar had net repayments of $400 million on this facility during the
    first six months of 1999. Equistar repaid approximately $385 million
    indebtedness outstanding under this facility in February 1999 with the
    proceeds of the offering of the outstanding notes.
(b) At June 30, 1999, the average interest rate under the $1.25 billion
    revolving credit facility was 5.8%.
(c) Lyondell remains liable on these debt obligations assumed by Equistar in
    connection with Equistar's formation to those debtholders, although
    Equistar and Lyondell have agreed that Equistar will indemnify Lyondell
    with respect to the assumed debt. As a result, as between Equistar and
    Lyondell, Lyondell is effectively secondarily liable.

   Covenants. Under the financial covenant provisions of the $1.25 billion
revolving credit facility, Equistar has agreed to

  . maintain a debt to capitalization ratio of no more than 0.60 to 1.0

  . maintain an interest coverage ratio which varies from period to period,
    as specified in the credit facility, and which is 2.25 to 1.0 for the
    period ended June 30, 1999

   Equistar is in compliance with each of the covenants under the $1.25 billion
revolving credit facility as of June 30, 1999. The terms of the $1.25 billion
credit facility, including the covenants and events of default, are described
in more detail under "Summary Description of Other Indebtedness of Equistar."

   The ability of Equistar to meet its debt service obligations and to comply
with the covenants and financial requirements in the $1.25 billion revolving
credit facility will largely depend on

  . the future performance of Equistar

  . the availability of additional financing to repay and refinance bank debt

Both of these circumstances will be influenced by prevailing economic and
competitive conditions and by other factors beyond Equistar's control. The
breach of any of the covenants or financial requirements in the $1.25 billion
revolving credit facility could result in a default, which would permit the
lenders to declare the loans immediately payable and to terminate future
lending commitments.

   Accounts Receivable. In December 1998, Equistar entered into an accounts
receivable sales facility providing for the ongoing sale of accounts
receivable. The facility provided $130 million in proceeds in 1998. The
accounts receivable sales facility expires in December 1999. Equistar used the
proceeds of this facility to reduce outstanding debt under the $500 million
credit facility. Fees associated with the sale of accounts receivable totaled
$0.4 million in 1998 and are included as general and administrative expenses.

Lyondell Contributed Business

 Revenues

   Sales and other operating revenues were $2.7 billion for the eleven months
ended November 30, 1997, compared to $2.5 billion in 1996. On an annualized
basis, sales and operating revenues increased 18%. This increase was due
primarily to increases in industry sales prices for ethylene and co-products.
Sales prices in the 1997 period showed significant increases over 1996 as
strong demand from the polymers markets resulted in a tighter balance of supply
and demand for olefins. Further, cost increases for olefins raw materials over
the course of 1996 were reflected in olefins product prices in the 1997 period.
In addition, olefins sales volumes increased due to strong demand in the
downstream markets as well as to planned and unscheduled industry maintenance
turnarounds. On an annualized basis, polymers revenues increased 7% due to
higher industry sales prices for polyethylene. These were partially offset by
decreased industry sales prices for polypropylene.

 Cost of Sales

   Cost of sales was $2.1 billion both in the 1997 period and in 1996. On an
annualized basis, cost of sales increased 10% or $214 million due primarily to
higher production levels to meet the demand for olefins, which increased cost
of sales by $518 million, and to increased polymers raw material costs caused
by tight supply and demand in the olefins markets, which increased cost of
sales by $59 million. These increases were slightly offset by lower raw
material costs for olefins, generally due to lower crude oil prices, which
decreased cost of sales by $363 million.

 Selling, General and Administrative Expenses

   Selling, general and administrative expenses increased from $157 million in
1996 to $166 million in the 1997 period. This increase of 15% or $24 million on
an annualized basis was primarily due to

  . $15 million for higher employee compensation due to headcount increases

  . $3 million for increased computer support costs related to software
    implementation

In addition, employee incentive compensation increased approximately $6 million
in 1997.

 Operating Income

   Operating income increased from $223 million in 1996 to $396 million in the
1997 period. On an annualized basis, the increase of 94% was due to higher
sales margins and sales volumes for olefins. Sales margins improved due to
higher olefins sales prices, resulting from strong demand in the downstream
markets for polyethylene and polypropylene, which also resulted in increased
sales volumes. Sales margins also benefited from lower petrochemical raw
material costs. The higher sales margins increased operating income by
approximately $261 million. These increases were slightly offset by lower sales
prices for polypropylene due to additional industry capacity in 1997, which
decreased operating income by approximately $15 million. There were also higher
polymers raw material costs in 1997 due to tighter supply and demand in the
olefins markets, which decreased operating income by approximately $59 million.
The higher product margins caused gross margin as a percentage of sales to
increase from 15% in 1996 to 21% in 1997.

 Interest Expense, Net

   Interest expense, net, decreased 15% on an annualized basis from 1996 to the
1997 period, primarily due to lower interest rates in 1997.

 Income Taxes

   The effective income tax rate during the 1997 period was 37.3% compared to
35.7% for 1996. The effective income tax rate increased in the 1997 period due
to the nondeductibility of executive compensation. State income tax was the
primary difference between the effective tax rate and the 35% federal statutory
rate during both years.

Millennium Contributed Business

 Revenues

   Sales and other operating revenues were $1,860 million in 1996 compared to
$1,786 million in the 1997 period. On an annualized basis, sales increased 5%.
This increase was attributable to strong demand, both domestically and in the
export markets, coupled with tight supply, resulting in prices rising through
the third quarter. Prices began to slowly weaken in fourth quarter 1997 as
expectations of new industry capacity coming on-stream and normal seasonal
slowdowns reduced demand and put pressure on prices.

 Cost of Sales

   Cost of sales was $1,503 million in 1996 compared to $1,341 million in the
1997 period. On an annualized basis, cost of sales decreased 3%. This decrease
was due to lower raw material costs, which declined from peak 1996 levels,
offset by higher production levels resulting from strong demand in 1997. Raw
material costs were on average 31% lower than the historical highs in 1996 as
warmer-than-normal winter weather reduced demand for natural gas and natural
gas liquids. These costs continued their decline in late 1997 as winter
temperatures remained above normal and crude oil inventories began building due
to decreased demand from Asian markets.

                                       35
<PAGE>

 Operating Income

   Operating income increased from $248 million in 1996 to $309 million in the
1997 period. On an annualized basis, the increase of 36% was primarily due to
an increase in average selling prices during the 1997 period coupled with lower
raw material costs. The resulting increase in product margins caused gross
margin as a percentage of sales to increase from 19% in 1996 to 25% in 1997.

 Interest Expense, Net

   Interest expense decreased from $80 million in 1996 to $66 million in the
1997 period. This annualized decrease of 10% was a result of a decrease in
outstanding debt.

 Income Taxes

   The effective income tax rate during the 1997 period was 39.5% compared to
45.2% for 1996. Differences between the effective income tax rates arise from
the different levels of income along with the effect of goodwill amortization
and state income tax, which are not deductible for federal tax purposes.

Environmental, Health and Safety Matters

   Equistar is subject to stringent environmental, health and safety laws and
regulations addressing air emissions, water discharges, generation, handling
and disposal of waste and other aspects of Equistar's operations. Equistar
devotes considerable efforts to comply with these laws and regulations, and in
so doing, it may incur significant capital expenditures and operating expenses.
Equistar spent $5 million in 1998 on environmental matters. Equistar
anticipates expenditures for environmental matters of $5 million in 1999 and $5
million in 2000.

   It is difficult to predict the future development of these laws and
regulations or their impact on Equistar's operations and products. In
particular, the future effect of the Clean Air Act may be significant. However,
future effects of the Clean Air Act are dependent upon the development of
future regulations and interpretations as well as other factors, such as the
development of environmental control technologies. Equistar's MTBE sales may
also be materially adversely affected by pending or future changes in laws or
regulations. The presence of MTBE in some water supplies in California, the
largest market for MTBE, and other states, due to gasoline leaking from
underground storage tanks, and in surface water from recreational watercraft
has led to public concern that MTBE may contaminate drinking water supplies and
thereby result in a possible health risk. There have been claims that MTBE

  . travels more rapidly through soil

  . is more soluble in water than most other gasoline components

  . is more difficult and more costly to remediate

Heightened public awareness about MTBE has resulted in federal and state
governmental initiatives that have sought either to rescind the oxygenate
requirement for reformulated gasoline or to restrict the use of MTBE. These
initiatives or other governmental actions could result in a significant
reduction in Equistar's MTBE sales.

   Equistar is also subject to liabilities and costs under Superfund and other
laws relating to investigation, cleanup or closure of former waste disposal
units or other areas of contamination. Investigation, cleanup and closure
responsibilities include both Equistar's facilities and third-party waste
facilities. Some Equistar facilities are currently undergoing assessment and
remedial actions under the Resource Conservation and Recovery Act. It is
difficult to predict how these liabilities and costs might be affected by
future changes, including more stringent cleanup standards and the discovery of
additional areas of contamination.

                                       36
<PAGE>

   Under indemnification arrangements in the asset contribution agreements with
Lyondell, Millennium Petrochemicals Inc., a subsidiary of Millennium, and the
contributing subsidiaries of Occidental, each of Lyondell, Millennium
Petrochemicals and the Occidental subsidiaries agreed to assume, and to
indemnify and defend Equistar against, some types of third-party claims and
liabilities which Equistar may incur relating to the pre-closing operation of
the contributed businesses. This obligation includes liabilities exceeding $7
million per contributed business asserted within the first seven years after
the date of the respective asset contributions.

   In its financial statements, Equistar reserves for contingencies that are
probable and reasonably estimable, including those based upon unasserted
claims. Based on current matters described above, Equistar has not established
any reserves for potential environmental issues and does not anticipate any
material adverse effect upon its earnings, operations or competitive position
resulting therefrom. However, the amount or timing of future environmental
liabilities and costs cannot be predicted with certainty, and liabilities and
costs could be material in future quarterly or annual results of Equistar's
operations for that period.

Year 2000

   Equistar uses many information technology or "IT" systems as well as non-IT
systems, such as manufacturing support and other systems, that could be
impacted by the "Year 2000 problem." The Year 2000 problem arises from computer
programs that have been written using two digits rather than four to designate
the year. Date-sensitive computer software may recognize a date using "00" as
the year 1900 rather than the year 2000, resulting in system failures or
miscalculations, potentially causing operational disruptions.

   Equistar has a Year 2000 Steering Committee, along with Lyondell and
LYONDELL-CITGO Refining, and has appointed representatives to Lyondell's Year
2000 Executive Sponsor Team. The Executive Sponsor Team provides oversight to
each member's steering committee. Equistar's steering committee is in the
process of completing an assessment of the state of readiness of the IT and
non-IT systems. The steering committee's assessments cover both

  . manufacturing systems, including laboratory information systems and field
    instrumentation

  . significant third-party vendor and supplier systems, including employee
    compensation and benefit plan maintenance related systems

The steering committee is also beginning to assess the readiness of significant
customers and suppliers, primarily through formal written representations as to
Year 2000 readiness. Suppliers of natural gas liquids and petroleum liquids,
the raw materials used in the production of olefins, as well as utility and
transportation providers, are critical to our business.

   In May 1997, before the formation of Equistar, Lyondell commenced the first
major use of new software for business information systems it contributed to
Equistar. The new systems, based on enterprise software from SAP America, Inc.,
replaced older business systems and allowed employees at different locations to
share financial and operating information more effectively. Equistar is in the
process of replacing the business information systems for the operations
contributed by Millennium Petrochemicals and Occidental with the same systems.
In November 1998, Equistar completed a system-wide implementation of SAP
America business information systems for its polymers business and a portion of
its petrochemicals business. Full business information systems conversion was
completed in the first half of 1999. The new systems and software are Year
2000-compatible, thus addressing the majority of Equistar's Year 2000 business
system requirements.

   Equistar's Year 2000 assessment process consists of an

  . inventory of Year 2000-sensitive equipment

  . assessment of the impact of possible failures

  . determination of the required remediation actions and testing

  . implementation of the solutions

   The inventory, assessment and remediation phases should be completed in
1999. The majority of the testing and final implementation is scheduled to take
place in 1999. The progress of these phases as of June 30, 1999 is summarized
as follows:




     [Bar chart appears here disclosing the percentage completion of each of
      inventory (99%), assessment (99%), remediation (99%), testing (95%)
                           and implementation (87%)]

   The inventory, assessment and remediation phases are expected to be
completed in third quarter 1999. The testing and implementation phases are also
expected to be completed in third quarter 1999. There are currently 200
employees working on the Year 2000 problem on a part time basis. Their time is
equivalent to 60 full-time employees working on the Year 2000 problem.

   As of June 30, 1999, Year 2000 spending and estimated spending by Equistar
is summarized as follows:

   As of June 30, 1999, spending to date by phase is as follows:

     .Inventory--$770,000

     .Assessment--$985,000

     .Remediation--$1,670,000

     .Testing and Implementation--$1,475,000

   As of June 30, 1999, estimated additional spending is as follows:

     .Inventory--$45,000

     .Assessment--$110,000

     .Remediation--$6,450,000

     .Testing and Implementation--$1,580,000

   The total estimated spending of $13 million represents the midpoint of the
estimated range between $11 million and $15 million. These spending estimates
will be refined as phases of the process are completed. Spending is funded by
cash generated from operations.

   Management believes that all significant systems controlled by Equistar will
be Year 2000 ready in the last half of 1999. Equistar's operations are
dependent on a continuous supply of key services from raw material suppliers
and utility and transportation providers. While the steering committee is
assessing the readiness of third-party customers and suppliers, there can be no
assurance that third parties with whom we have a significant business
relationship will successfully test, reprogram and replace all of their IT and
non-IT systems on a timely basis. A failure of key raw materials suppliers to
address Year 2000 issues could interfere with their ability to make and cause
delivery of products. This, in turn, could cause disruptions in the chemical
industry, including Equistar's operations, resulting in the idling of capacity.
These potential disruptions could make it necessary to seek alternative sources
of supply, which may be more expensive or difficult to obtain. Approximately
97% of Equistar's raw materials suppliers have indicated that they will be Year
2000 compliant by third quarter 1999. Equistar is developing contingency plans
with the assistance of an outside consultant. The final plans, when
implemented, are intended to avoid material interruption of core business
operations through the year 2000 and beyond, while ensuring safe operations and
optimal financial performance. The contingency planning will involve an
analysis of critical business processes and an identification of the most
likely threats to these processes. Solutions and alternatives will be developed
for these internal or external threats. Equistar completed its analysis and
plan development in mid-year 1999, and implementation is to be completed in the
last half of the year.

   There is inherent uncertainty in the Year 2000 problem due to the
possibility of unanticipated failures by third-party customers and suppliers.
Accordingly, Equistar is unable, at this time, to assess the extent and
resulting materiality of the impact of possible Year 2000 failures on its
operations, liquidity or financial position. In a worst case scenario,
controlled plant shutdowns using Equistar's standard shutdown procedures might
be necessitated by failure of utility providers or suppliers or by internal
conditions affecting plant operability. Such events could have a material
adverse effect on Equistar's operations, liquidity or financial position. In
the event of a plant shutdown, Equistar would evaluate the need to reroute or
reschedule the production at another Equistar facility or to find alternative
suppliers for its customers. The Year 2000 assessment process is expected to
provide information that will significantly reduce the level of uncertainty
regarding the Year 2000 impact. Management believes that the completion of the
assessment and remediation plan as scheduled will help minimize the possibility
of any significant disruptions of Equistar's operations.

Accounting Standards

   In 1998, Equistar adopted Statement of Financial Accounting Standards
("SFAS") No. 130, "Reporting Comprehensive Income." SFAS No. 130 establishes
standards for the reporting and display of comprehensive

                                       39
<PAGE>

income and its components. SFAS No. 130 requires all items that are required to
be recognized under accounting standards as components of comprehensive income
to be reported in a financial statement that is displayed with the same
prominence as other financial statements. The effect of adoption of SFAS No.
130 in 1998 did not have a material impact on the financial statements of
Equistar.

   In 1998, Equistar adopted SFAS No. 131, "Disclosures about Segments of an
Enterprise and Related Information." SFAS No. 131 supercedes SFAS No. 14,
"Financial Reporting for Segments of a Business Enterprise," replacing the
"industry segment" approach with the "management" approach. The management
approach designates the internal organization that is used by management for
making operating decisions and assessing performance as the source of
Equistar's reportable segments. SFAS No. 131 also requires disclosures about
products and services, geographic areas and major customers. The adoption of
SFAS No. 131 did not have a material impact on the financial statements of
Equistar.

   In 1998, Equistar adopted SFAS No. 132, "Employers' Disclosures about
Pensions and Other Retirement Benefits." The provisions of SFAS No. 132 revise
employers' disclosures about pension and other postretirement benefit plans.
SFAS No. 132 does not change the measurement or recognition of these plans.
SFAS No. 132 standardizes the disclosure requirements for these plans, to the
extent practicable. The adoption of SFAS No. 132 did not have a material impact
on the financial statements of Equistar.

   In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities." The statement
is effective for Equistar's fiscal year 2001; however, early adoption is
permitted. SFAS No. 133 requires that all derivative instruments be recorded on
the balance sheet at their fair value. Changes in fair value of derivatives are
recorded each period in current earnings or in other comprehensive income,
depending upon whether a derivative is designated as part of a hedge
transaction and, if it is, the type of hedge transaction. The gains and losses
on the derivative instrument that are reported in other comprehensive income
will be reclassified as earnings in the periods in which earnings are impacted
by the hedged item. The ineffective portion of all hedges will be recognized in
current period earnings. Equistar does not intend to adopt this pronouncement
before 2001. The adoption of this pronouncement is not expected to have a
material impact on the financial statements of Equistar.

                           Disclosure of Market Risk

Commodity Price Risk

   A substantial portion of Equistar's products and raw materials are
commodities whose prices fluctuate as market supply and demand fundamentals
change. Accordingly, product margins and the level of Equistar's profitability
tend to fluctuate with changes in the business cycle. Equistar tries to protect
against such instability through various business strategies. These strategies
include increasing the olefins plants' ability to change between different
types of raw materials, entering into multi-year processing and sales
agreements and moving downstream into derivatives products whose pricing is
more stable. Equistar has not used derivative instruments for commodity hedging
purposes.

Interest Rate Risk

   The interest rate on Equistar's $1.25 billion revolving credit facility is a
floating rate. The use of floating rate debt instruments provides benefit
during times of downward interest rate movements but represents exposure to
risk from future interest rate increases. Based on the June 30, 1999 floating
interest rate of 5.8% and the amount outstanding under the $1.25 billion
revolving credit facility at June 30, 1999 of $750 million, a 10% change in
interest rate would result in an increase or decrease of interest expense of
approximately $75 million on an annual basis. This exposure may be limited by
our ability to select a different interest rate mechanism under the $1.25
billion revolving credit facility.

                       Description of Equistar's Business

   Equistar is one of the largest chemical producers in the world with total
1998 pro forma revenues of $5 billion and $7 billion of assets at the end of
1998. It is the world's second largest, and North America's largest, producer
of ethylene, the world's most widely used petrochemical. Equistar is also the
largest producer of polyethylene and propylene in North America.

   Olefins, the generic name for ethylene and propylene, and their co-products
are basic building blocks used to create a wide variety of products. Ethylene
is used to produce polyethylene, ethylene oxide and its primary derivative,
ethylene glycol, ethylene dichloride and ethylbenzene. Polyethylene is used to
produce packaging film, trash bags and lightweight high-strength plastic
bottles for milk, juices, shampoos and detergents. Propylene is used to produce
polypropylene, which is used in products such as plastic caps and other
closures, rigid packaging and carpet facing and backing. Substantially all of
Equistar's revenues are derived from sales in North America.

   Equistar was formed to maximize the long-term cash flow and economic value
creation potential of its contributed businesses. Management believes that
Equistar's operations to date have provided and will continue to provide
opportunities for significant cost savings and expanded business opportunities,
leading to improved earnings and cash flow. The strengths inherent in the
combined businesses, including the multiple locations and the ability to
alternate between different types of raw materials provide Equistar with
competitive advantages that exceed those which were available to Lyondell,
Millennium and Occidental, individually.

Equistar's Business Strategies

   Equistar's business strategies include

  . Achieving savings or "synergy" targets in earnings and cash flow by
    operating the Lyondell, Millennium and Occidental contributed businesses
    as a single entity and continuing to reduce costs by focusing on

    --aligning and improving the efficiency of processing units for
     improved on-stream processing time and increased capacity

    --maximizing the value of the ability to alternate between different
     types of raw materials and olefins co-products produced in the olefins
     operations

    --lowering distribution costs through high-volume purchases and sales

    --reducing raw materials and other purchasing costs

  . Realizing maximum value from the strategic flexibility and optimization
    potential inherent in Equistar's large number of plant sites, in the
    ability to alternate between different types of raw materials and in a
    broad selection of polymer products

  . Focusing on capital projects designed to increase reliability and
    undertaking cost efficient expansions of value-added product lines by

    --realizing the benefits of its recently completed 125-million-pound
     HDPE expansion at its Victoria facility by continuing to develop its
     established sales base in high value products

    --completing a 480-million-pound HDPE resin expansion project at its
     Matagorda facility for late 1999 start-up to support high molecular-
     weight HDPE film growth

  . Pursuing a market strategy of expanding value-added businesses using
    minimal capital by increasing production and sales volumes in key
    markets, such as high and medium molecular-weight HDPE film resins,
    specialized HDPE injection molding resins and wire and cable resins

  . Leveraging technology by

    --pursuing research on alternative olefins raw material technology as a
     method to lower costs and gain competitive advantages

                                       41

    --integrating Lyondell proprietary catalyst technology with Millennium
     process technologies, enabling Equistar to produce higher-margin,
     value-added polymer products

   The following chart illustrates the ability of our olefins processing
units, or crackers, to use different types of raw materials for ethylene
production and the breakdown of ethylene consumption.




[Flowchart showing the production path of feedstocks at Equistar's olefins
plants or "crackers," the plants' products and the downstream customers and
end-uses of the products appears here. Equistar's NGL crackers refine ethane,
propane and butane to produce ethylene. Equistar's Petroleum Liquid Crackers
refine condensate, naphtha, kerosene and diesel to produce ethylene.
Equistar's ethylene production is used as a feedstock by Equistar's ethylene
oxide and derivatives plants and its polymers operations, and by plants
operated by Lyondell, Millennium and Occidental. A portion of Equistar's
ethylene production is sold to unrelated third parties. Equistar uses ethylene
for the production of ethylene oxide and derivatives, the enduses of which
include detergents, industrial cleaners, polyester fiber, antifreeze and brake
fluid. Equistar's polymers operations use the ethylene to produce polyethylene
(LDPE, LLDPE and HDPE), which is used in grocery and trash bags, food
packaging films, plastics caps and closures, milk and water bottles, drink
cups and toys. Occidental uses ethylene to produce ethylene dichloride, which
is used in the manufacture of PVC drain pipe, vinyl flooring and siding.
Millennium uses ethylene in its vinyl acetate operations; vinyl acetate is
used in household adhesives, paint and ice bags. Lyondell uses ethylene for
the production of styrene, enduses of which include polystyrene cups, packages
and cutlery.

Equistar's petroleum liquid crackers also produce butadiene, aromatics,
gasoline, fuel oil and propylene. A portion of the propylene produced by
Equistar is used by Equistar's polymers operations and by Lyondell; the
balance is sold to unrelated third parties. Equistar's polymers operations use
the propylene to produce polypropylene which in turn is used in carpet fibers,
housewares and auto bumpers. Lyondell uses the propylene to produce propylene
oxide, which is used in polyurethane foam for furniture and insulation.]

Financial Statements of Equistar Chemicals, LP.

Petrochemicals Segment

   Petrochemicals are fundamental to many segments of the economy, including
the production of consumer products, housing components, automotive products
and other durable and nondurable goods. We produce petrochemicals, including
olefins, aromatics and oxygenated chemicals, at twelve facilities located in
six states. Olefins include ethylene, propylene and butadiene. Aromatics
include benzene and toluene. Oxygenated chemicals include ethylene oxide,
ethylene glycol, ethanol and MTBE. Our petrochemical products are used to
manufacture polymers and intermediate chemicals, which are used in a variety
of consumer and industrial products. Ethylene is the most significant
petrochemical in terms of worldwide production volume. Ethylene is also the
key building block for polyethylene and a large number of other chemicals,

With the strong growth of end-use products derived from ethylene during the
past several decades, especially as plastics have developed into low-cost,
high-performance substitutes for a wide range of materials such as metals,
paper and glass, U.S. ethylene consumption has grown by an average annual rate
of approximately 4%.

   The Chocolate Bayou, Corpus Christi and two Channelview, Texas olefins
plants use petroleum liquids as raw materials, including naphtha, condensates
and gas oils (collectively "petroleum liquids"), to produce ethylene. The cost
of ethylene production from petroleum liquids has historically been less than
the cost of producing ethylene from natural gas liquids, including ethane,
propane and butane (collectively "NGLs"). The use of petroleum liquids results
in the production of a significant amount of co-products, such as propylene,
butadiene, benzene and toluene, and of specialty products such as
dicyclopentadiene, isoprene, resin oil, piperylenes, hydrogen and alkylate.
Based upon an independent third-party survey, we believe our Channelview
facility is the lowest production cost ethylene facility in North America. Our
Morris, Illinois; Clinton, Iowa; Lake Charles, Louisiana; and LaPorte, Texas
plants are designed to use NGLs, which primarily produce ethylene with some co-
products such as propylene. In addition, we are currently modifying the LaPorte
plant to run some forms of petroleum liquids, such as condensate. A
comprehensive pipeline system connects our plants along the Gulf Coast with
major olefins customers. Raw materials are sourced both internationally and
domestically and are shipped via vessel and pipeline.

   We produce ethylene oxide and its primary derivative, ethylene glycol, at
facilities located in Pasadena, Texas and through PD Glycol, a 50% joint
venture with DuPont de Nemours and Company, in Beaumont, Texas. The Pasadena
facility also produces other derivatives of ethylene oxide, principally ethers
and ethanolamine. Ethylene glycol is used in antifreeze and in polyester
fibers, resins and films. The other ethylene oxide derivatives are used in many
consumer and industrial end uses, such as detergents and surfactants, brake
fluids and polyurethane foams for seating and bedding.

   We produce synthetic ethyl alcohol at the Tuscola, Illinois plant by a
process that combines water and ethylene, referred to as direct hydration.
Equistar also owns and operates facilities in Newark, New Jersey and Anaheim,
California for denaturing ethyl alcohol. In addition, it produces small volumes
of diethyl ether, a byproduct of its ethyl alcohol production, at Tuscola.
These ethyl alcohol products are ingredients in various consumer and industrial
products, as described more fully in the table below.

   The following table outlines our petrochemical products, our annual
processing capacity and the primary uses for these products. Unless otherwise
specified, in the table below, processing capacity was calculated by estimating
the number of days in a typical year that a production unit of a plant is
expected to operate, after allowing for downtime for regular maintenance, and
multiplying that number by an amount equal to the unit's optimal daily output
based on the current design raw material mix. Because processing capacity of a
production unit is an estimated amount, actual production volumes may be more
or less than the processing capacity listed.

 Raw Materials and Ethylene Purchases for Our Petrochemicals Segment

   The raw material cost for olefins production is generally the largest
component of total cost for the petrochemicals business. Olefins plants with
the flexibility to consume a wide range of raw materials are better able to
maintain higher levels of profitability during periods of changing energy and
petrochemicals prices than olefins plants that are restricted in their raw
material processing capability. The primary feedstocks used in the production
of olefins are petroleum liquids, also referred to as "heavy raw materials,"
and NGLs, also referred to as "light raw materials." As of January 1, 1999,
approximately 44% of domestic ethylene industry capacity was limited to NGL raw
materials. As of January 1, 1999, approximately 56% of domestic capacity
processed to some extent both NGLs and petroleum liquids or only petroleum
liquids.

   Petroleum liquids have had a historical variable margin advantage over NGLs
such as ethane and propane. For example, using petroleum liquids typically
generates between one and four cents additional margin per pound of ethylene
produced compared to using ethane. We have the capability to realize this
margin advantage at the Channelview, Corpus Christi and Chocolate Bayou
facilities. This variable margin advantage is expected to continue due to the
significantly higher capital cost for plants with the capability to process
both heavy raw materials, or petroleum liquids, and their resulting co-products
in contrast to processing light raw materials, or NGLs.

<PAGE>

   The following chart illustrates, for the fourth quarter of 1998, our
percentage usage of heavy raw materials and light raw materials as compared
with industry usage, based on industry sources.




[CHART APPEARS HERE]


   The Channelview facility is unusually flexible in that it can process 100%
petroleum liquids or up to 80% NGLs. The Corpus Christi plant can process up to
70% Petroleum Liquids or up to 70% NGLs. The Chocolate Bayou facility processes
100% petroleum liquids. Equistar's four other olefins facilities currently
process only NGLs. We are currently upgrading the LaPorte facility to integrate
the operations of the LaPorte and Channelview facilities. The upgrade will
permit the LaPorte facility to process 25% to 30% petroleum liquids and the
Channelview facility to process the co-products resulting from the processing
of petroleum liquids.

   The majority of our petroleum liquids requirements are purchased via
contractual arrangements from a variety of third-party domestic and foreign
sources. We also purchase a minimal amount of petroleum liquids from third-
party domestic and foreign sources selling goods via the spot market at the
market rate at time of purchase. We also purchase NGLs from a wide variety of
domestic sources. We obtain a portion of our olefins raw material requirements
from LYONDELL-CITGO Refining at market-related prices.

   In addition to producing our own ethylene, we assumed some agreements of an
affiliate of Millennium for the purchase of ethylene from Gulf Coast producers
at market prices. Ethylene purchase obligations under these contracts will
decline to zero at the end of 2000.

 Marketing, Sales and Distribution of Our Petrochemicals Segment

   Ethylene produced by the LaPorte, Morris and Clinton facilities is generally
consumed as raw material by the polymers operations at those sites. Ethylene
and propylene produced at the Channelview, Corpus Christi, Chocolate Bayou and
Lake Charles olefins plants are generally distributed by pipeline or via
exchange agreements to our Gulf Coast polymer and ethylene oxide facilities as
well as to other third parties. As of January 1, 1999, approximately 75% of the
ethylene we produced was consumed internally or sold to our affiliates based on
current market prices. See "Related Transactions."

   With respect to sales to third parties, we sell a majority of olefins
products to customers with whom Lyondell and Occidental have had long-standing
relationships. Sales to third parties generally are made under

                                       46
<PAGE>

written agreements. These written agreements typically provide for

  . monthly negotiation of price

  . customer purchase of a specified minimum quantity

  . three- to six-year terms with automatic one- or two-year term extension
    provisions

Some contracts may be terminated early if deliveries have been suspended for
several months.

   Ethylene oxide and ethylene glycol are sold under long-term contracts of
three-to-five years' duration to third-party customers, with pricing negotiated
on a quarterly basis to reflect market conditions.

   Glycol ethers are sold primarily into the solvent and distributor markets
under one-year contracts at market prices, as are ethanolamines and brake
fluids.

   Ethanol and ethers are sold to third-party customers under one-year
contracts at market prices.

   We license MTBE technology under a license from an affiliate of Lyondell and
sell a significant portion of MTBE produced at one of our two Channelview units
to Lyondell at market-related prices. The production from the second unit is
consumed by LYONDELL-CITGO Refining for gasoline blending. MTBE produced at
Chocolate Bayou is sold to third parties at market-related prices.

   We sell most of our aromatics production under contracts that have initial
terms ranging from two to three years and that typically contain automatic one-
year term extension provisions. These contracts generally provide for monthly
or quarterly price adjustments based upon current market prices. Aromatics
produced by LYONDELL-CITGO Refining, with the exception of benzene, are
marketed by Equistar for LYONDELL-CITGO Refining under contracts with similar
terms to its own. Benzene produced by LYONDELL-CITGO Refining is sold directly
to Equistar at market-related prices.

   Most of the ethylene and propylene production of the Channelview, Chocolate
Bayou, Corpus Christi and Lake Charles facilities are shipped via a 1,430-mile
pipeline system which has connections to numerous Gulf Coast ethylene and
propylene consumers. This pipeline system, some of which we own and some of
which we lease, extends from Corpus Christi to Mont Belvieu to Port Arthur,
Texas as well as around the Lake Charles area. In addition, exchange agreements
with other olefins producers allow access to customers who are not directly
connected to our pipeline system. Some propylene is shipped by ocean-going
vessel. Ethylene oxide and its derivatives are shipped by rail car. Butadiene,
aromatics and other petrochemicals are distributed by pipeline, railcar, truck,
barge or ocean-going vessel.

 Competition and Industry Conditions in the Petrochemicals Segment

   The basis for competition in our petrochemicals products is price, product
quality, the ability to deliver product when and where the customer wants and
customer service. We compete with other large domestic producers of
petrochemicals, including

     . BP Amoco Chemical Company

     . Chevron Chemical Company

     . Dow Chemical Company

     . Exxon Chemical Company

     . Huntsman Chemical Company

     . Mobil Chemical Company

     . Phillips Petroleum Company

     . Shell Chemical Company

     . Union Carbide Corporation

   The combined processing capacity of our ethylene units at January 1, 1999
was approximately 11.5 billion pounds of ethylene per year or approximately 17%
of total North American production capacity. Based on published rated
production capacities, we believe we are the largest producer of ethylene in
North America. North American ethylene processing capacity at January 1, 1999
was approximately 62 billion pounds per year. Of the total ethylene production
capacity in the United States, approximately 95% is located along the Gulf
Coast. Approximately 80% of U.S. production capacity is owned by nine
manufacturers.

   The following chart illustrates our production capacity position for
ethylene both in North America and worldwide as of January 1, 1998, based on
industry sources.

   Petrochemicals profitability is affected by the level of demand for
petrochemicals and derivatives along with vigorous price competition among
producers which may intensify due to, among other things, the addition of new
capacity. In general, weak economic conditions, either in the United States or
in the world, and higher raw material costs tend to reduce demand and/or put
pressure on margins. Capacity additions in excess of annual growth also put
pressure on margins. In addition, in recent years, industry consolidation has
occurred, a trend which we expect will continue. It is not possible to predict
accurately the changes in raw material costs, market conditions and other
factors which will affect petrochemical industry margins in the future.

   The petrochemicals industry has historically experienced significant
volatility in capacity utilization and profitability. Producers of olefins
primarily for merchant supply to unaffiliated customers typically experience
greater variations in their sales volumes and profitability in comparison to
more integrated competitors when industry supply and demand relationships are
at extremes. This is due primarily to a higher proportion of captive demand for
olefins derivatives production experienced by the more integrated competitors.
We currently consume or sell approximately 75% of our ethylene production to
downstream derivatives facilities owned by us or one of our partners, which has
the effect of reducing volatility.

   Our other major commodity chemical products also experience cyclical market
conditions similar to, although not necessarily coincident with, those of
ethylene.

Polymers Segment

   Through twelve facilities located in four states, our polymers segment
manufactures a wide variety of polyolefins, including polyethylene,
polypropylene and various performance polymers.

   We currently manufacture polyethylene using a variety of technologies at six
facilities in Texas and at our Morris and Clinton facilities. The Morris and
Clinton facilities are the only polyethylene facilities located in the Midwest.
These facilities enjoy a freight cost advantage over Gulf Coast producers in
delivering products to customers in the Midwest and on the East Coast of the
United States. Polyethylene is used in a wide variety of consumer products,
packaging materials and industrial applications.

   Our Morris, Illinois and Pasadena, Texas facilities manufacture
polypropylene using propylene produced as a co-product of our ethylene
production and propylene purchased from third parties. Polypropylene is sold
for various applications in the automotive, housewares and appliance
industries. We also produce performance polymer products, which include
enhanced grades of polyethylene and polypropylene, at several of our polymers
facilities. We believe that, over a business cycle, average selling prices and
profit margins for performance polymers tend to be higher than average selling
prices and profit margins for higher volume commodity polyethylenes.

   We produce wire and cable resins and compounds at Morris, Illinois; La
Porte, Texas; Tuscola, Illinois; and Fairport Harbor, Ohio. Wire and cable
resins and compounds are used to insulate copper and fiber optic wiring in
power, telecommunication and computer and automobile applications.

   The following table outlines our polymers and performance polymers products,
our annual processing capacity, the primary uses for these products and our
brand names. Unless otherwise specified, in the table below, processing
capacity was calculated by estimating the number of days in a typical year that
a production unit of a plant is expected to operate, after allowing for
downtime for regular maintenance, and multiplying that number by an amount
equal to the unit's optimal daily output based on the current design raw
material mix. Because processing capacity of a production unit is an estimated
amount, the actual production volumes may be more or less than the processing
capacity listed.

(a) We increased our HDPE capacity by approximately 125 million pounds in 1998.
    A 480-million-pound HDPE resin expansion project at the Matagorda facility
    has a targeted start-up in the third quarter of 1999. The idling of a
    portion of the Port Arthur facility effective March 31, 1999 resulted in a
    decrease in capacity of 300 million pounds at the end of the first quarter
    of 1999.
(b) These are enhanced grades of polyethylene and are included in the capacity
    figures for HDPE, LDPE and LLDPE above, as appropriate.

   Research and development for our polymers segment is conducted in
laboratories at our Cincinnati, Ohio facility and at pilot plants in Matagorda,
Texas and Morris, Illinois. These facilities provide product and process
technology support for the polymers segment and its customers. See "--Research
and Technology; Patents and Trademarks Owned or In Use by Equistar."

 Raw Materials for Our Polymers Segment

   With the exception of the Chocolate Bayou polyethylene plant, our
polyethylene and polypropylene production facilities can receive their ethylene
and propylene directly from our petrochemical facilities. The raw material is
sent via our olefins pipeline system at our own production at the site. The
polyethylene plants at Chocolate Bayou, LaPorte, Port Arthur and Pasadena are
pipeline-connected to third parties and can receive ethylene via exchanges or
purchases. The polypropylene facility at Morris also receives propylene from a
third party.

 Marketing, Sales and Distribution for Our Polymers Segment

   Our polymers products are primarily sold to an extensive base of established
customers. Approximately 30% of these customers have term contracts typically
having a duration of one to three years. The remainder is generally sold
without contractual term commitments. In either case, in most of the continuous
supply relationships prices may be changed upon mutual agreement with our
customers.

   Polymers are primarily distributed via railcar. We own or lease, under long-
term lease arrangements, approximately 10,000 railcars for use in our polymers
business. We sell our polymers products in the United States primarily through
our own sales organization. The sales organization generally engages sales
agents to market its products in the rest of the world.

 Competition and Industry Conditions in Our Polymers Segment

   The basis for competition in our polymers products is

    . product performance

    . product quality

    . the ability to deliver product when and where the customer wants it

    . customer service

    . price

   We compete with other large producers of polymers, including Chevron
Chemical Corporation, Dow Chemical Company, Eastman Chemical Company, Exxon
Chemical Company, Formosa Plastics, Huntsman Chemical Company, NOVA
Corporation, Phillips Petroleum Company, Solvay Polymers, Total Fina, Union
Carbide Corporation and Westlake Polymers. Polymers profitability is affected
by the worldwide level of demand for polymers along with vigorous price
competition, which may intensify due to, among other things, new domestic and
foreign industry capacity. In general, weak economic conditions either in the
United States or elsewhere in the world tend to reduce demand and put pressure
on margins. It is not possible to predict accurately the changes in raw
material costs, market conditions and other factors that will affect polymers
industry margins in the future.

   Based on published rated industry capacities, we are the largest producer of
polyethylene in North America and a leading domestic producer of polyolefins
powders, compounds, wire and cable resins, and polymers for adhesives. The
combined processing capacity of our polyethylene units as of January 1, 1999
was approximately 6.2 billion pounds per year or approximately 16% of total
industry capacity in North America. There are approximately 19 other North
American producers of polyethylene, including Chevron Chemical Company, Dow
Chemical Company, Exxon Chemical Company, Phillips Petroleum Company, Solvay
Polymers and Union Carbide Corporation. Our polypropylene capacity, 680 million
pounds per year as of January 1, 1999, represents approximately 4.5% of the
total North American polypropylene capacity. There are approximately 14 other
North American competitors in the polypropylene business, including BP Amoco
Chemical Company, Exxon Chemical Company, Montell Polyolefins BV and Total
Fina.

   The following chart illustrates our production capacity position for
polyethylene and polypropylene, or "polyolefins," for 1998, based on industry
sources.

   We use an extensive olefins pipeline system, some of which we own and some
of which we lease, extending from Corpus Christi to Mont Belvieu to Port Arthur
and around the Lake Charles area. We own other pipelines in connection with our
Morris, Clinton, Tuscola, Chocolate Bayou, Matagorda, Victoria, Corpus Christi
and LaPorte facilities. We own and lease several pipelines connecting the
Channelview facility, the refinery owned by LYONDELL-CITGO Refining and the
Mont Belvieu storage facility; these pipelines are used to transport raw
materials, butylenes, hydrogen, butane, MTBE and unfinished gasolines. We also
own a barge docking facility near the Channelview facility capable of berthing
eight barges and related terminal equipment for loading and unloading raw
materials and products. We own or lease, under long-term lease arrangements,
approximately 10,000 railcars for use in our business.

   We sublease our executive offices and corporate headquarters from Lyondell
in downtown Houston, Texas. In addition, we own facilities which house the
Morris and Cincinnati research operations. We also lease sales facilities and
storage facilities, primarily in the Gulf Coast area, from various third
parties for the handling of products.

Research and Technology; Patents and Trademarks Owned or In Use by Equistar

   We maintain a significant research and development facility in Cincinnati,
Ohio. The Cincinnati facility features more than 30 plastics processing lines,
all of commercial or semi-commercial size, allowing our engineers and
technicians to evaluate polyolefins products under conditions similar to a
customer's plant. We also have additional research facilities in Morris,
Illinois, Matagorda, Texas and Plano, Texas. Product development efforts are
aimed at tailoring products to meet specific customer needs.

   The Channelview facility employs proprietary technology owned by Lyondell to
convert ethylene and other light petrochemical streams into propylene. We are
conducting a research project to investigate alternative raw materials for use
at the Channelview, Chocolate Bayou and/or Corpus Christi facilities. These
alternative raw materials could significantly lower costs and provide an
additional competitive advantage at these facilities.

   Recent polymers industry announcements relate to the development of single-
site catalysts. Successful development and commercialization of these catalysts
are expected to result in enhanced polymer properties. We are conducting a
broad search to evaluate outside technology and are concentrating in-house
research in an effort to identify and develop single-site catalysts for use in
the production of polyolefins resins. We hold several United States patents and
the rights to several patents pending in connection with research and
development efforts in this area. We are not dependent upon obtaining or
retaining any particular patent, and believe the failure to receive or retain
any individual patent would not have a material effect on operations.

   We use numerous technologies in our operations, many of which are licensed
from third parties. Significant licenses we hold include

    . BP Amoco fluid bed polyethylene process for the production of both
  LLDPE and HDPE

    . Unipol process for the production of LLDPE

    . other licenses for the production of polyethylene and polypropylene

We are not dependent on the retention of any particular license and believe
that the loss of any individual license would not have a material adverse
effect on operations.

   We acquired rights to numerous recognized brand names from Lyondell and
Millennium Petrochemicals Inc., a wholly owned subsidiary of Millennium, in
connection with the formation of Equistar. The brand names are ALATHON(R),
KromaLon(R), Petrothene(R), Ultrathene(R), Vynathene(R) and Microthene(R). Our
rights to use these trademarks are perpetual as long as we actively use the
trademarks. We are not dependent upon any particular trademark and believe the
loss of any individual trademark would not have a material adverse effect on
operations.

Employee Relations

   As of March 31, 1999, we employed approximately 5,000 full-time employees.
We also use the services of independent contractors in the routine conduct of
our business. Approximately 365 hourly workers are covered by collective
bargaining agreements. We believe that our relations with our employees are
good.

Equistar's Long-Term Incentive Plan

   In 1998 Equistar offered a performance-driven, long-term incentive plan, or
LTIP, to selected key employees. The LTIP is an integrated current and deferred
bonus system. Awards are based on whether Equistar reaches its performance and
financial goals in critical areas, primarily economic value added and the
achievement of synergies. Economic value added measures Equistar's cash flow
performance in excess of a capital charge, which is calculated by multiplying
the capital invested in Equistar by Equistar's weighted average cost of
capital. Synergies include both one-time and ongoing potential savings from
operating the Lyondell, Millennium and Occidental contributed businesses
together. Synergy targets include each of

  . aligning and improving the efficiency of processing units for improved
    processing time and increased capacity capability

  . maximizing the value of raw material and olefins co-products

                                       58
<PAGE>

  . lowering distribution costs

  . reducing the cost of raw materials and other purchasing costs

  . reducing the amount of staffing services required by each contributed
    business

   The partnership governance committee has discretion to make awards based on
its assessment of Equistar's operating performance in the preceding year,
primarily in the areas of synergy attainment and economic value added.

   Equistar currently assigns each LTIP participant a target award percentage
for the year based on that participant's position and any other factors
Equistar deems appropriate. Each LTIP participant's award for the year is
determined by multiplying his/her target award percentage by an award multiple
determined by the partnership governance committee, the product of which is
multiplied by his/her base pay. The award multiple for 1998 was based on the
achievement of a four-year rolling average economic value added of $160 million
and the achievement of net synergies of $50 million.

   Awards will generally be paid only to LTIP participants who are actually
employed at year-end. Those LTIP participants whose employment terminates due
to death, disability or retirement before the end of the year will be paid a
pro rata portion of their award based on the number of full months completed
while actively employed. All other participants terminated with or without
cause are subject to forfeiture of their award. LTIP participants hired after
the first of the year are eligible to receive a pro rata award based on the
number of full months completed during the year.

   Awards consist of a combination of annual or current cash and deferred cash
compensation. The relative percentages of current cash and deferred cash
components are based on the LTIP participant's salary range. The percentage of
deferred cash compensation as compared with current cash compensation increases
as the LTIP participant's salary increases. The current portion of the award is
disclosed under the "Bonus" column of the Summary Compensation Table above. The
deferred cash portion of the award is paid out over three consecutive years,
one-third each year, beginning approximately one year from the payment of the
related annual cash component. In 1998, the payout amounts for the deferred
compensation component could be adjusted upward, with no cap, or downward,
capped at 20%, based on Equistar's ongoing results with respect to synergies
over that three-year period. Awards could be adjusted one percentage point for
every percentage point of synergy gained or lost during the award period.

   The following table details the amount of the deferred compensation
component of the 1998 award to the four most highly paid executive officers as
well as their estimated future payouts resulting from such award under the
LTIP.

Annual Pension Benefits Offered by Equistar

 Pension Plan

   In 1998, Equistar adopted a pension plan available to all full-time or
regular part-time Equistar employees and those employees on an approved long-
term disability leave of absence. The pension plan is fully funded by Equistar.
Employees are not required, nor are they allowed, to contribute to the pension
plan. Participation began for former Lyondell, Millennium Petrochemicals and
Occidental employees on their first day of service with Equistar. All other
employees are eligible on the first day following 12 months of service with
Equistar or any predecessor company. Participation in the pension plan ends on
the earliest of the day the employee

  . quits, retires, is discharged or dies

  . is absent from work more than 12 consecutive months

  . is no longer eligible for benefits

Benefits are not reduced for social security or other amounts.

   Annual retirement benefit under the pension plan is calculated by
multiplying

  . the pension plan participant's years of service to Equistar after January
    1, 1998, by

  . Final Average Earnings as defined below, by

  . the Benefit Percentage as shown below

"Final Average Earnings" is the pension plan participant's highest average
monthly base pay received for any 36 consecutive months during the last 120
months of continuous service with Equistar or Lyondell, Millennium
Petrochemicals or Occidental. For pension plan participants with less than 36
months of continuous service with Equistar or Lyondell, Millennium
Petrochemicals or Occidental, Final Average Earnings is the average of all
monthly base pay, including salary, earned with Equistar, Lyondell, Millennium
Petrochemicals or Occidental.

   The Benefit Percentage applicable to each pension plan participant is based
on the participant's age when he begins to receive benefits, as shown in the
following table:

 Supplemental Executive Retirement Plan

   Equistar offers a Supplemental Executive Retirement Plan ("SERP") to senior
managers and executive officers who receive a retirement benefit under the
pension plan and who have had the amount of that benefit reduced due to
required limitations under the Internal Revenue Code of 1986, as amended, or
under the Employee Retirement Income Security Act, as amended ("ERISA").
Calculation of benefits under the SERP is based on

  . base wage

  . salary deferrals, and

  . annual incentive awards

Equistar bears all costs of the SERP, including administration of the SERP.
SERP participants are not allowed to contribute to the SERP. The SERP provides
for two types of supplementary benefits: deferral/incentive supplements and
qualification limitation supplements.

   Deferral/Incentive Supplements. Participants are eligible for a
deferral/incentive supplement under the SERP if their Excess Retirement
Benefit, as defined below, is a positive amount. The monthly amount of
supplemental benefits is calculated by multiplying the SERP participant's
Excess Retirement Benefit by a fraction based on his/her years of service. For
purposes of this paragraph, Excess Retirement Benefit is

  . the amount the SERP participant would have received at retirement as a
    basic allowance from the pension plan if it included the SERP
    participant's awards and deferred compensation, minus

  . the amount of monthly retirement allowance the SERP participant is
    actually entitled to receive at retirement under the pension plan

   The total annual benefit payable to each SERP participant, including payment
under the pension plan, shall not exceed 65% of the greater of

  . the SERP participant's final base pay, exclusive of deferrals, and most
    recent annual incentive pay, or

  . the highest average base pay plus annual incentive pay during a 36-month
    consecutive period out of 120 months of service with Equistar or
    Lyondell, Millennium Petrochemicals or Occidental

   Qualification Limitation Supplements. SERP participants are eligible for a
qualification limitation supplement if their Excess Retirement Benefit, as
defined below, is a positive amount. The monthly amount of qualification
limitation supplement benefit is calculated by multiplying the SERP
participant's Excess Retirement Benefit by a fraction based on the SERP
participant's years of service. For purposes of this paragraph, Excess
Retirement Benefit is

  . the amount of monthly allowance the SERP participant would have received
    as a base allowance under the pension plan had the amount not been
    limited or reduced due to requirements under the Internal Revenue Code of
    1986, as amended, or ERISA

    minus

  . the amount of monthly allowance the SERP participant is actually entitled
    to receive at retirement

   SERP participants may elect to receive their SERP benefit in any form
available for payment of their normal retirement benefit, provided that the
same form of payment is elected for all supplementary benefits. If the SERP
participant elects a form of annuity for these supplementary benefits, the SERP
participant must elect the same form of annuity under the pension plan.
Benefits are not reduced for social security or other amounts.

Indemnification Arrangements with Equistar's Executive Officers

   The partnership governance committee has provided for the indemnification of
Equistar's executive officers. Executives are entitled to indemnification with
respect to all matters to which Section 145 of the General Corporation Law of
the State of Delaware may relate, as if Section 145 were applicable to a
partnership. The right to indemnification and payment of expenses incurred in
defending a proceeding in advance of its final disposition is not exclusive of
any other right which the executive may have or hereafter acquire under any
statute, agreement or otherwise, both as to action in that executive's official
capacity and as to action in any other capacity by holding this office. The
indemnification right continues after the executive ceases to serve as an
Equistar officer or to serve another entity at the request of Equistar.
Equistar may elect to enter into individual indemnification agreements with
each of its executive officers and with any other persons as the partnership
governance committee may designate. In addition, Equistar may elect to maintain
liability insurance to protect itself and any executive officer of Equistar or
another partnership, corporation, joint venture, trust or other enterprise
against any expense, liability or loss, whether or not Equistar would have the
power to indemnify this person against expense, liability or loss under the
laws of the State of Delaware.

                    Description of the Partnership Agreement

   The partnership agreement of Equistar governs, among other things,
ownership, cash distributions, capital contributions and management of
Equistar. The following is a summary of the material provisions of the
partnership agreement. This summary is qualified in its entirety by reference
to the full and complete text of the partnership agreement, which is available
upon written request as provided under "Available Information."

 Background

   Lyondell GP, Lyondell LP, Millennium GP and Millennium LP entered into the
partnership agreement as of October 10, 1997. PDG Chemical Inc., Occidental LP1
and Occidental LP2 became parties to the partnership agreement as of May 15,
1998. PDG Chemical Inc. withdrew from Equistar as of June 30, 1998, and
Occidental GP became a general partner on the same date. Equistar will continue
in existence until its dissolution as provided in the partnership agreement.
The three general partners of Equistar are Lyondell GP, Millennium GP and
Occidental GP. Lyondell GP is a direct wholly owned subsidiary of Lyondell.
Millennium GP is an indirect wholly owned subsidiary of Millennium. Occidental
GP is an indirect wholly owned subsidiary of Occidental.

   Equistar's general partners are single purpose entities which do not hold
any significant assets other than partnership interests. Each general partner
holds less than 1% of an interest in Equistar.

 Governance of Equistar

   A partnership governance committee manages and controls the business,
property and affairs of Equistar, including the determination and
implementation of Equistar's strategic direction. The general partners exercise
their authority to manage and control Equistar only through the partnership
governance committee. The partnership governance committee consists of nine
members, called representatives, three of whom are representatives of Lyondell
GP, three of whom are representatives of Millennium GP and three of whom are
representatives of Occidental GP.

   In general, the approval of two or more representatives acting for Lyondell
GP will be necessary and sufficient for the partnership governance committee to
take any action. This means, in effect, that Lyondell GP's representatives have
the ability to control the partnership governance committee and, as a result,
Equistar, except where the approval of Millennium's and Occidental's general
partner representatives is required. See "--Actions Requiring Unanimous
Voting." Even though ordinary actions by the partnership governance committee
may be approved by two representatives of Lyondell GP, the partnership
governance committee may not take any action at a meeting with respect to any
matter that was not reflected on an agenda that was properly delivered to all
of the representatives in advance, unless at least one of each of Millennium
GP's and Occidental GP's representatives is present. The participation rights
of any general partner's representatives may be curtailed to the extent that
the general partner or its affiliates cause a default under the partnership
agreement.

 Actions Requiring Unanimous Voting

   Unless approved by two or more representatives of each of Lyondell GP,
Millennium GP and Occidental GP, the partnership governance committee may not
directly or indirectly take, or commit to take, the actions described below.
Equistar, any subsidiary of Equistar or any person acting in the name of or on
behalf of any of them, directly or indirectly, may not take or commit to take,
whether in a single transaction or a series of related transactions

  . to cause Equistar, directly or indirectly, to engage, participate or
    invest in any business outside the scope of its business as described in
    the partnership agreement

  . to approve any strategic plan, as well as any amendments or updates to
    the strategic plan, including the annual update described under "--
    Strategic Plans and Preparation of an Annual Budget" below

  . to authorize any disposition of assets having a fair market value
    exceeding $30 million in any one transaction or a series of related
    transactions not contemplated in an approved strategic plan

                                       66
<PAGE>

  . to authorize any acquisition of assets or any capital expenditure
    exceeding $30 million that is not contemplated in an approved strategic
    plan

  . to require capital contributions to Equistar within any fiscal year if
    the total of contributions required from the partners within that year
    would exceed $100 million or if the total of contributions required from
    the partners within that year and the immediately preceding four years
    would exceed $300 million. This does not apply to

    --contributions contemplated by the asset contribution agreements

    --an approved strategic plan

    --requirements made to achieve or maintain compliance with health,
      safety and environmental laws

    --after giving effect to the incurrence of the debt and any related
     transactions, Equistar would be expected to have an "investment grade"
     debt rating by Moody's and S&P's, or

    --the debt is incurred to refinance the public or bank debt assumed or
     incurred by Equistar as contemplated by documents relating to the
     formation of Equistar and the contribution of the Occidental
     contributed business or to refinance any such refinancing debt

    and in the case of each of the three exceptions above, the agreement
    relating to the debt does not provide that the transfer by a partner of
    its partnership interests, or a change of control with respect to any
    partner or any of its affiliates, would either

    --constitute a default under the debt instruments

    --otherwise accelerate the maturity of the debt

    --give the lender or holder any "put rights" or similar rights with
     respect to the debt instrument

  . to authorize a refinancing that would not satisfy provisions relating to
    the Millennium guaranteed debt and the Occidental reference debt

  . to make borrowings under one or more of Equistar's bank credit
    facilities, uncommitted lines of credit or any credit facility, or debt
    instruments that refinances all or any portion of Equistar's credit
    facility or facilities, at any time, if, as a result of any borrowing,
    the aggregate principal amount of all borrowings outstanding at the time
    would exceed the sum of $1.75 billion

  . to enter into interest rate protection or other hedging agreements, other
    than hydrocarbon hedging agreements, in the ordinary course of business

  . to enter into any capitalized lease or off-balance sheet financing
    arrangements involving payments, individually or in the aggregate, by it
    in excess of $30 million in any fiscal year

  . to cause Equistar or any subsidiary of Equistar to issue, sell, redeem or
    acquire any partnership interests in Equistar or other equity securities,
    or any rights to acquire, or any securities convertible into or
    exchangeable for, partnership interests or other equity securities

    --LYONDELL-CITGO Refining, its successors or assigns

    --Lyondell Methanol, its successors or assigns

    --any other affiliate of either Lyondell GP, Millennium GP or
     Occidental GP, if the affiliate's actions with respect to the conflict
     circumstance are not controlled by Lyondell, Millennium or Occidental,
     other than a business conflict involving the exercise of any rights
     and remedies with respect to a default under any agreement that is the
     subject of the conflict

  . to repay any of the indebtedness that is guaranteed by the Millennium
    America guarantee before December 1, 2004, or refinance any Millennium-
    guaranteed debt before December 1, 2004, if any of the principal amount
    of debt refinancing the guaranteed debt would be due and payable after
    December 1, 2004; provided, however, that if the Millennium-guaranteed
    debt continues to be guaranteed by Millennium America or its successors
    after December 1, 2004, then the term of the debt shall not exceed 365
    days

  . to repay any of the Occidental reference debt before June 14, 2005, other
    than through refinancing, or refinance any Occidental reference debt
    before June 14, 2005, if any of the principal of the debt refinancing
    Occidental reference debt would be due and payable after June 14, 2005;
    provided, however, that if Occidental reference debt continues to be
    guaranteed by an affiliate of Occidental or its successors or the
    reference for determination of the amount of the obligation of Occidental
    Chemical to contribute to Equistar pursuant to a specified indemnity
    agreement after June 14, 2005, then the term of the debt shall not exceed
    365 days

   Although unanimous approval by all nine members of the partnership
governance committee is never required, the requirements described above are
referred to as "unanimous voting requirements" because two

                                       68
<PAGE>

representatives of each of the general partners must agree on any action taken
in respect of the enumerated matters.

 Transactions with Affiliates

   Except as described above under "--Actions Requiring Unanimous Voting," if a
business conflict caused by any transaction or dealing between Equistar, or any
of its subsidiaries, and one or more of Equistar's general partners, or any of
their affiliates, occurs, the other general partners will have sole and
exclusive power, at the expense of Equistar, to both

  . control all decisions, elections, notifications, actions, exercises or
    nonexercises and waivers of all rights, privileges and remedies provided
    to, or possessed by, Equistar with respect to the conflict

  . retain and direct legal counsel and to control, assert, enforce, defend,
    litigate, mediate, arbitrate, settle, compromise or waive any and all
    claims, disputes and actions if any potential, threatened or asserted
    claim, dispute or action about a conflict occurs

Accordingly, any action by the partnership governance committee with respect to
a conflict, except as described above, will require the approval of at least
two representatives of the uninvolved general partners.

 Officers of Equistar

   The executive officers of Equistar consist of a Chief Executive Officer, a
President and Chief Operating Officer and others as determined from time to
time by the partnership governance committee. See "Management." Except for the
Chief Executive Officer, the approval of at least two representatives of each
of Lyondell GP, Millennium GP and Occidental GP is required to appoint or
discharge executive officers, based upon the recommendation of the Chief
Executive Officer. However, any of Lyondell GP, Millennium GP or Occidental GP
may, by action of two or more of its representatives, remove from office any
executive officer of Equistar, including the Chief Executive Officer, who
takes, or causes Equistar to take, any action described above under "--Actions
Requiring Unanimous Voting" without the required approval of two or more
representatives of each of Lyondell GP, Millennium GP and Occidental GP.

   The Chief Executive Officer holds office for a five-year term, assuming he
does not resign or die and is not removed. Upon the expiration of his term or
earlier vacancy, Lyondell GP will designate the Chief Executive Officer,
provided that this person shall be reasonably acceptable to Millennium GP and
Occidental GP. The Chief Executive Officer will not be required to be an
employee of Equistar. The Chief Executive Officer may be removed at any time by
action of the partnership governance committee, meaning that the approval of
only two representatives of Lyondell GP is required to effect a removal.

   The Chief Executive Officer of Equistar has general authority and
discretion, comparable to that of a chief executive officer of a publicly held
Delaware corporation of similar size, to direct and control the business and
affairs of Equistar, including, without limitation, its day-to-day operations
in a manner consistent with the annual budget and the most recently approved
strategic plan. The Chief Executive Officer takes steps to implement all orders
and resolutions of the partnership governance committee. The Chief Executive
Officer also establishes salaries or other compensation for the other executive
officers of Equistar consistent with plans approved by the partnership
governance committee.

 Strategic Plans and Preparation of an Annual Budget

   Equistar is managed under a five-year strategic plan which is updated
annually under the direction of the Chief Executive Officer and presented for
approval by the partnership governance committee no later than 90 days before
the start of the first fiscal year covered by the updated plan. The strategic
plan must be approved each year by at least two representatives of each of
Lyondell GP, Millennium GP and Occidental GP. The strategic plan establishes
the strategic direction of Equistar, including

  . plans relating to capital maintenance and enhancement

  . geographic expansion, acquisitions and dispositions

                                       69
<PAGE>

  . new product lines

  . technology

  . long-term supply and customer arrangements

  . internal and external financing

  . environmental and legal compliance

  . plans, programs and policies relating to compensation and industrial
    relations

   In addition, the executive officers of Equistar prepare an annual budget for
each fiscal year. Each annual budget includes an operating budget and capital
expenditure budget. Each annual budget must be consistent with the information
for its fiscal year included in the most recently approved strategic plan.
Unless otherwise provided in the most recently approved strategic plan, each
annual budget utilizes a format and provides a level of detail consistent with
Equistar's previous annual budget.

   If for any fiscal year the partnership governance committee fails to approve
an updated strategic plan, for that year and each subsequent year before the
approval of an updated strategic plan, the executive officers of Equistar will
prepare an annual budget consistent with the projections and other information
for that year included in the strategic plan most recently approved. The Chief
Executive Officer, acting in good faith, shall be entitled to modify any annual
budget

  . to satisfy current contractual and compliance obligations and/or

  . to account for other changes in circumstances resulting from the passage
    of time or the occurrence of events beyond Equistar's control

The Chief Executive Officer is not authorized to cause Equistar to proceed with
capital expenditures to accomplish capital enhancement projects except to the
extent that the expenditures would enable Equistar to continue or complete any
capital project reflected in the last strategic plan that was approved by the
partnership governance committee.

 Solutions for Partnership Governance Committee Deadlock

   After a strategic plan and an annual budget have been approved by the
partnership governance committee, or an annual budget has been developed as
described above in cases where an updated strategic plan has not yet been
approved, the Chief Executive Officer is authorized, without further action by
the partnership governance committee, to cause Equistar to make expenditures
consistent with the updated strategic plan and annual budget, provided that all
internal control policies and procedures, including those regarding the
required authority for expenditures, shall have been followed.

   If the partnership governance committee has not agreed upon and approved an
updated strategic plan by 12 months after the beginning of the first fiscal
year that would have been covered by the plan, then Lyondell GP, Millennium GP
and Occidental GP are required to submit to a nonbinding dispute resolution
process. The partners are required to continue the dispute resolution process
until either

  . agreement is reached by the general partners, acting through their
    representatives on an updated strategic plan

  . at least 24 months have elapsed since the beginning of the first fiscal
    year that was to be covered by the first updated strategic plan for which
    agreement was not reached

   Once 24 months have elapsed, one general partner will determine and notify
the other general partners in writing that no agreement resolving the dispute
is likely to be reached. Following receipt of notice, any general partner may
elect to dissolve Equistar.

                                       70

 Distribution of Available Net Operating Cash to Equistar's Partners

   Equistar shall distribute to the partners, as soon as practicable following
the end of each month, all Available Net Operating Cash, as defined below. On a
cumulative basis

  . distributions are to be made to the extent of cumulative profits to the
    partners in the ratio of the percentage interest owned by each partner

  . the remaining distributions are to be made to Equistar's limited partners
    in the ratio of their percentage interest

See "Ownership."

   "Available Net Operating Cash" is defined in Equistar's partnership
agreement, at the relevant time of determination, as

  . all cash and cash equivalents on hand at Equistar as of the most recent
    month's end, plus the excess, if any, of Equistar's targeted level of
    indebtedness over Equistar's actual indebtedness as of that month's end,

    less

  . the Projected Cash Requirements, if any, of Equistar as of that month's
    end, as determined by Equistar's executive officers

   Equistar's targeted level of indebtedness is shown in the most recently
updated strategic plan. Equistar's actual indebtedness is determined according
to generally accepted accounting principles and represents all short term and
long term debt.

   "Projected Cash Requirements" means, for the 12-month period following any
month's end, the excess, if any, of the sum of

  . forecast capital expenditures

  . forecast cash payments for taxes, debt service, including principal and
    interest payment requirements and other noncash credits to income

  . forecast cash reserves for future operations or other requirements

    over the sum of

  . forecast net income of Equistar

  . the sum of forecast depreciation, amortization, other noncash charges to
    income, interest expense and tax expenses, in each case to the extent
    deducted in determining net income

  . forecast decreases in working capital or minus forecast increases in
    working capital

  . the forecast cash proceeds of disposition of assets, net of expenses

  . an amount equal to the forecast net proceeds of debt financings and
    capital contributions

   Projected Cash Requirements for Equistar shall be calculated consistently
with the most recently updated strategic plan, except to the extent Equistar's
executive officers determine that changes in Equistar's financial condition,
results of operations, assets, business or prospects make a change advisable,
in which case Equistar shall promptly advise the general partners regarding the
basis for the change.

   Distributions to the partners of cash or property arising from a liquidation
of Equistar will be made according to the capital account balances of the
partners.

   Any amount otherwise distributable to a partner as described above will be
applied by Equistar to satisfy any of the following obligations that are owed
by a partner or its affiliate to Equistar and that are not paid when

                                       71
<PAGE>

due, unless otherwise agreed by the general partners not involved with a
business conflict as described under "--Transactions with Affiliates" above for
a partner's failure

  . to pay any interest or principal when due on any indebtedness for
    borrowed money of the partner or its affiliate to Equistar

  . to make any indemnification payment required by its asset contribution
    agreement that has been finally determined to be due or the failure of
    that partner's affiliate

  . to make any capital contribution required by the partnership agreement,
    other than as required by its asset contribution agreement

 Indemnification of Equistar's Partners

   Equistar has agreed, to the fullest extent permitted by applicable law, to
indemnify, defend and hold harmless each partner, its affiliates and its
respective officers, directors and employees. This indemnification is from,
against and in respect of any liability which that person may sustain, incur or
assume as a result of, or relative to, any third-party claim arising out of or
in connection with the business, property or affairs of Equistar. This
indemnification does not apply to the extent that it is finally determined that
the third-party claim arose out of or was related to actions or omissions of
the indemnified partner, its affiliates or any of their respective officers,
directors or employees acting in those capacities constituting a breach of
Equistar's partnership agreement or any related agreement. This indemnification
obligation is not intended to, nor will it, affect or take precedence over the
indemnity provisions contained in any related agreement.

 Transfers and Pledges of a Partner's Interest in Equistar

   Without the consent of the partnership governance committee, no partner may
transfer less than all of its interest in Equistar. If an Equistar limited
partner and its affiliated general partner desire to transfer, via a cash sale,
all of their units, they must give written notice to Equistar and the other
partners stating

  . their desire to transfer their partnership interests

  . the cash purchase price

  . all other terms on which they are willing to sell

   Delivery of this initial notice will constitute the irrevocable offer by the
selling partners to sell their partnership interest. The nonselling partners
shall have the option, exercisable by delivering written acceptance notice of
the exercise to the selling partners within 45 days after receiving notice of
the sale, to elect to purchase all of the partnership interests of the selling
partners on the terms described in the initial notice. If all of the other
nonselling partners deliver notice of acceptance, then all of the partnership
interests shall be transferred in proportion to the partners' current
percentage interest unless otherwise agreed. If less than all of the nonselling
partners deliver notice of acceptance, the partner who delivers notice of
acceptance will have the option of purchasing all of the partnership interests
up for sale. The notice of acceptance will set a date for closing the purchase
which is not less than 30 nor more than 90 days after delivery of the notice of
acceptance, subject to extension. The purchase price for the selling partners'
partnership interests will be paid in cash. The cash shall be delivered at the
closing.

   If the nonselling partners do not elect to purchase the selling partners'
partnership interests within 45 days after the receipt of initial notice of
sale, the selling partners will have a further 180 days during which they may
consummate the sale of their units to a third-party purchaser. The sale to a
third-party purchaser must be at a purchase price and on other terms that are
no more favorable to the purchaser than the terms offered to the Equistar
partners. If the sale is not completed within the 180-day period, the initial
notice will be deemed to have expired, and a new notice and offer shall be
required before the selling partners may make any transfer of their partnership
interests.

                                       72
<PAGE>

   Before the selling partners may consummate a transfer of their partnership
interests to a third party under the partnership agreement, the selling
partners will demonstrate the suitability of the proposed purchaser as an
Equistar partner. The person willing to serve as the proposed purchaser's
guarantor must have outstanding indebtedness that is rated investment grade by
Moody's and S&P's. If the proposed guarantor has no rated indebtedness
outstanding, it shall provide an opinion from a nationally recognized
investment banking firm that it could be reasonably expected to obtain suitable
ratings. In addition, a partner may transfer its partnership interests only if

  . the transferee executes an appropriate agreement to be bound by the
    partnership agreement

  . the transferor and/or the transferee bears all reasonable costs incurred
    by Equistar in connection with the transfer

  . the guarantor of the transferee delivers an agreement to the ultimate
    parent entity of the nonselling partners and to Equistar substantially in
    the form of the parent agreement

   A partner will not in any transaction or series of actions, directly or
indirectly, pledge all or any part of its partnership interest. However, a
partner may at any time assign its right to receive distributions from Equistar
so long as the assignment does not purport to assign any

  . right of the partner to participate in or manage the affairs of Equistar

  . right of the partner to receive any information or accounting of the
    affairs of Equistar

  . right of the partner to inspect the books or records of Equistar

  . any other right of a partner under the partnership agreement or the
    Delaware Revised Uniform Limited Partnership Act

In addition, except for any restrictions imposed by the parent agreement,
nothing in Equistar's partnership agreement will prevent the transfer or pledge
by the owner of any capital stock, equity ownership interests or other security
of the partner or any affiliate of a partner.

 Business Opportunities Which Must be Offered to Equistar

   Except as described below, each partner's affiliates are free to engage in
or possess an interest in any other business of any type and to avail
themselves of any business opportunity available to it without having to offer
Equistar or any partner the opportunity to participate in that business. If a
partner's affiliate desires to initiate or pursue an opportunity to undertake,
engage in, acquire or invest in a "related business," as defined in the
partnership agreement, that partner or its affiliate will offer Equistar the
business opportunity.

   A "related business" is any business related to

  . the manufacturing, marketing and distribution of the types of olefins,
    polyolefins, ethyl alcohol and ethyl ether and ethylene oxide, ethylene
    glycol and derivatives of ethylene oxide and ethylene glycol that are
    specific in the partnership agreement

  . the purchasing, processing and disposing of raw materials in connection
    with the manufacturing, marketing and distributing of the chemicals
    identified in the previous bulletpoint, and

  . any research and development in connection with the previous two
    bulletpoints


   When a proposing partner offers a business opportunity to Equistar, Equistar
will elect to do one of the following within a reasonably prompt period

  . acquire or undertake the business opportunity for the benefit of Equistar
    as a whole, at the cost, expense and benefit of Equistar

                                       73
<PAGE>

  . permit the proposing partner to acquire or undertake the business
    opportunity for its own benefit and account without any duty to Equistar
    or the other partners

   If the business opportunity is in direct competition with the then-existing
business of Equistar, then the proposing partner and Equistar shall, if either
so elects, seek to negotiate and implement an arrangement whereby Equistar
would either

  . acquire or undertake the competing opportunity at the sole cost, expense
    and benefit of the proposing partner under a mutually acceptable
    arrangement. Under the arrangement, the competing opportunity will be
    treated as a separate business within Equistar. The proposing partner
    bears costs, expenses and benefits of the separate business

     or

  . enter into a management agreement with the proposing partner to manage
    the competing opportunity on behalf of the proposing partner. The
    management agreement will be on terms and conditions mutually acceptable
    to the proposing partner and Equistar.

If Equistar and the proposing partner do not reach agreement as to an
arrangement, the proposing partner may acquire or undertake the competing
opportunity for its own benefit and account without any duty to Equistar or the
other partners.

   In addition, if the business opportunity constitutes less than 25% of an
acquisition of or investment in assets, activities, operations or businesses
that is not otherwise a related business, then a proposing partner may acquire
or invest in a business opportunity without first offering it to Equistar. The
25% figure is based on annual revenues for the most recently completed fiscal
year. After completion of the above acquisition or investment, the proposing
partner must offer the business opportunity to Equistar under the terms
described above. If Equistar elects to pursue the business opportunity, it will
be acquired by Equistar at its fair market value as of the date of the
acquisition.

   Equistar will permit the first general partner and its affiliates to acquire
or undertake a business opportunity, and the business opportunity shall be
treated in the same manner as if the general partners and its affiliates were a
proposing partner with respect to the business opportunity if

  . Equistar is presented with an opportunity to acquire or undertake a
    business opportunity that it determines not to acquire or undertake

  . the representatives of one general partner, but not the other general
    partners, desire that Equistar acquire or undertake the business
    opportunity

                      Description of the Parent Agreement

   Lyondell, Millennium, Occidental, Occidental Chemical Corporation, Oxy CH
Corporation and Equistar are parties to an amended and restated parent
agreement and, along with Occidental Chemical Holding Corporation, an
assignment and assumption agreement. The parent agreement, as modified by the
assignment and assumption agreement, provides for, among other things, a
guarantee of the obligations of their respective subsidiaries by each of
Lyondell, Millennium and Occidental Chemical Holding (the "Guarantor Parents"),
transfer restrictions with respect to the stock of the subsidiaries that hold
the direct interests in Equistar (the "Partner Sub Stock") and a requirement to
present specified business opportunities to Equistar. The following is a
summary of the material provisions of the parent agreement as modified by the
assignment and assumption agreement, which is available upon written request as
provided under "Available Information."

 Guarantee of Obligations Under the Partnership Agreement and Related Party
 Agreements

   Each of the Guarantor Parents has guaranteed, undertaken and promised to
cause the due and punctual payment and the full and prompt performance of all
of the amounts to be paid and all of the terms and provisions to be performed
or observed by or on the part of its Affiliated Obligors, as defined below,
under various agreements, including, without limitation, the partnership
agreement and the asset contribution agreements, by its respective
subsidiaries. The subsidiaries are as follows

  . Lyondell GP and Lyondell LP in the case of Lyondell (the "Lyondell
    Partner Subs")

  . Millennium GP and Millennium LP in the case of Millennium (the
    "Millennium Partner Subs")

  . Occidental GP, Occidental LP1 and Occidental LP2 in the case of
    Occidental Chemical Holding (the "Occidental Partner Subs")

The Occidental Partner Subs, Lyondell Partner Subs and Millennium Partner Subs,
and any other direct or indirect subsidiary of any of the Guarantor Parents
that are parties to the other agreements defined below are collectively
referred to as the "Affiliated Obligors." The guarantee extends, according to
the terms of the other agreements, as follows

  . in the event that its Affiliated Obligors fail in any manner whatsoever
    to timely pay, perform or observe any of the terms and provisions of
    other agreements, the Guarantor Parent will either

    --itself duly and punctually pay, or fully and promptly perform or
     observe, as the case may be, the terms and provisions

    --cause the same to be duly and punctually paid, or fully and promptly
     performed or observed

  . in each of the above, the Guarantor Parent will act as if the Guarantor
    Parent were itself the obligor with respect to the terms and provisions
    under other agreements

Insofar as the foregoing relates to the obligations of an Affiliated Obligor
under Equistar's partnership agreement, no Guarantor Parent will be required to
make, or cause a Partner Sub to make, any contribution to Equistar that the
Partner Sub is not otherwise required to make under terms of Equistar's
partnership agreement concerning required capital contributions. Insofar as the
provisions described in this subsection apply to agreements other than the
partnership agreement and the parent agreement, the term "Affiliated Obligors"
will not include Equistar or any partner of Equistar in its capacity as a
partner. The parent agreement provides expressly that the parent guarantees
inure solely to the benefit of the beneficiaries specified in the parent
agreement, which consist of Equistar, Lyondell, Millennium, Occidental and the
Affiliated Obligors. The parent agreement also states that nothing in the
agreement confers upon any other person any rights, benefits or remedies by
reason of the parent agreement. Accordingly, the holders of the notes may not
enforce any provision, or seek relief by reason, of the parent agreement.

                                       75

 Conflict Circumstance

   The provisions described under the caption "Guarantee of Obligations Under
the Partnership Agreement and Related Party Agreements" do not apply to terms
and provisions of other agreements that are within the scope of the provisions
described in this subsection. Equistar's partnership agreement includes
definitions of "Conflicted General Partner" and "Nonconflicted General Partner"
and provides that the Nonconflicted General Partners have some exclusive rights
to control Equistar with respect to any Conflict Circumstance. Without limiting
the rights of its Partner Sub under the partnership agreement, and without
prejudice to any rights, remedies or defenses Equistar may have in any other
agreement or Conflict Circumstance, each of Lyondell, Millennium and Occidental
Chemical Holding has agreed to cause its Partner Sub to both

  . cause Equistar to pay, perform and observe all of the terms and
    provisions of other agreements to be paid, performed or observed by or on
    the part of Equistar under the agreements, according to their terms to
    the extent that the Partner Sub is a Nonconflicted General Partner and is
    thereby entitled to cause the payment, performance and observance of the
    terms and provisions

  . except to the extent inconsistent with its obligations above, abide by
    its obligations as a Nonconflicted General Partner with respect to any
    conflict circumstance arising in connection with any other agreement
    according to the terms of the partnership agreement that apply; each of
    Lyondell's, Millennium's or Occidental Chemical Holding's responsibility
    for a failure of Equistar to pay, perform or observe its obligations
    under the other agreements shall be limited to the circumstances in which
    Equistar's failure to so pay, perform or observe its obligations under
    the other agreements was directly caused by an act or failure to act by
    its Partner Sub

Nothing in the provisions described in this subsection shall require Lyondell,
Millennium or Occidental Chemical Holding to make or cause the Partner Sub to
either

  . cure or mitigate any inability of Equistar to make any payment or to
    perform or observe any terms and provisions under any other agreements

  . cause Equistar to require from the Partner Subs any cash contributions in
    respect of any payment, performance or observance involving a conflict
    circumstance

  . make any contribution to Equistar that the Partner Sub is not otherwise
    required to make under terms of the partnership agreement concerning
    required capital contributions

See "Description of the Partnership Agreement--Transactions with Affiliates."

 Restrictions on Transfer of Partner Sub Stock

   Without the consent of each of Lyondell, Millennium, Oxy CH and Occidental
Chemical (the "Ownership Parents"), none of Lyondell, Millennium, Occidental
Chemical or Oxy CH may transfer less than all of its Partner Sub Stock except
in compliance with the following provisions.

   Each of Lyondell, Millennium, Oxy CH or Occidental Chemical may transfer
all, but not less than all, of its Partner Sub Stock, without the consent of
the other Ownership Parents, if the transfer is in connection with either

  . a merger, consolidation, conversion or share exchange of the Ownership
    Parent

  . a sale or other disposition of

    --the Partner Sub Stock

     plus

    --other assets representing at least 50% of the book value of the
     Ownership Parent's assets (or in the case of each of Oxy CH and
     Occidental Chemical, 50% of the book value of Oxy CH's assets)
     excluding the Partner Sub Stock, as reflected on its most recent
     audited consolidated or combined financial statements

Following the consummation of any transaction involving Oxy CH or Occidental
Chemical, the Partner Sub Stock held directly or indirectly by Oxy CH and
Occidental Chemical on the date of the parent agreement shall

                                       76
<PAGE>

be held by the same transferee or one or more transferees that are wholly owned
affiliates of each other or of a common parent entity.

   In addition, any transfer of Partner Sub Stock by any Ownership Parent
described above is only permitted if the acquiring, succeeding or surviving
entity, if any, both

  . succeeds to and is substituted for the transferring Ownership Parent with
    the same effect as if it had been named in the parent agreement

  . executes an instrument agreeing to be bound by the obligations of the
    transferring Ownership Parent under the parent agreement, with the same
    effect as if it had been named in the instrument

The transferring Ownership Parent may be released from its guarantee
obligations under the parent agreement after the successor parent agrees to be
bound by the Ownership Parent's obligations.

   Unless a transfer is permitted under the provisions described above, any
Ownership Parent desiring to transfer all of its Partner Sub Stock to any
person, including another Ownership Parent or any affiliate of an Ownership
Parent, may only transfer its Partner Sub Stock for cash consideration and will
give written notice to Equistar and each of the other Ownership Parents. The
notice will state

  . the selling parent's desire to transfer its Partner Sub Stock

  . the cash purchase price, and

  . all other terms on which the selling parent is willing to sell

   Each offeree parent will have the option to elect to purchase all of its
proportional share, in the case of both of the limited partner and general
partner, of all of the Partner Sub Stock of the selling parent. The option to
purchase is on the terms described in the initial notice of sale. If one of the
selling parents, but not the other, elects to so purchase, the selling parent
shall give written notice thereof to the offeree parent electing to purchase,
and that parent shall have the option to purchase all of the Parent Sub Stock
held by the selling parent, including the Partner Sub Stock it has not
previously elected to purchase. Any election by an offeree parent not to
purchase all of the Partner Sub Stock shall be deemed a rescission of the
parent's original notice of acceptance and an election not to purchase any of
the Partner Sub Stock of that selling parent. If one or both of the offeree
parents do not elect to purchase all of the selling parent's Partner Sub Stock
within 45 days after the receipt of the initial notice or within 15 days after
the receipt of the notice to an offeree parent electing to purchase, if
applicable, the selling parent will have a further 180 days during which it
may, subject to the provisions of the following paragraph, consummate the sale
of its Partner Sub Stock to a third-party purchaser. The sale to a third-party
purchaser may be at a purchase price and on other terms that are no more
favorable to the purchaser than the initial terms offered to the offeree
parents. If the sale is not completed within the further 180-day period, the
initial notice of sale will be deemed to have expired and a new notice and
offer shall be required before the selling parent may make any transfer of its
Partner Sub Stock.

   Before the selling parent may consummate a transfer of its Partner Sub Stock
to a third party under the provisions described in the foregoing two
paragraphs, the selling parent shall demonstrate to the other Ownership Parents
that the proposed purchaser, or the person willing to serve as its guarantor as
contemplated by the terms of the parent agreement, has outstanding indebtedness
that is rated investment grade by either Moody's or S&P. If such proposed
purchaser or the other person has no rated indebtedness outstanding, that
person shall provide an opinion from Moody's, S&P or from a nationally
recognized investment banking firm that it could be reasonably expected to
obtain a suitable rating. Moreover, an Ownership Parent may transfer its
Partner Sub Stock, under the previous two paragraphs, only if all of the
following occur:

  . the transfer is accomplished in a nonpublic offering in compliance with,
    and exempt from, the registration and qualification requirements of all
    federal and state securities laws and regulations

                                       77
<PAGE>

  . the transfer does not cause a default under any material contract which
    has been approved unanimously by the partnership governance committee and
    to which Equistar is a party or by which Equistar or any of its
    properties is bound

  . the transferee executes an appropriate agreement to be bound by the
    parent agreement

  . the transferor and/or transferee bears all reasonable costs incurred by
    Equistar in connection with the transfer

  . the transferee, or the guarantor of the obligations of the transferee,
    delivers an agreement to each of the other Ownership Parents and Equistar
    substantially in the form of the parent agreement

  . the proposed transferor is not in default in the timely performance of
    any of its material obligations to Equistar

   In no event may any Ownership Parent transfer the Partner Sub Stock of any
of its Partners' subs to any person unless the Ownership Parent simultaneously
transfers the Partner Sub Stock of its other partners' sub or subs to the
person or a wholly owned affiliate of the person or a common parent.

 Competing Business by Partners of Equistar or Their Affiliates

   If any of Lyondell, Millennium or Occidental Chemical, Oxy CH or Occidental
Chemical Holding or any of their affiliates desires to initiate or pursue any
opportunity to undertake, engage in, acquire or invest in a business
opportunity, it shall agree to offer that business opportunity to Equistar
under the terms and conditions in the partnership agreement as if it were the
"proposing partner," as described above in "Description of the Partnership
Agreement--Business Opportunities Which Must be Offered to Equistar." Equistar
will have the rights and obligations arising from the offer of the business
opportunity granted by the partnership agreement. See "Description of the
Partnership Agreement--Business Opportunities Which Must be Offered to
Equistar."

                              Related Transactions

   All of the related transactions described below were obtained on terms
substantially no more favorable than those that would have been agreed upon by
third parties on an arm's length basis.

 Asset Contributions by Lyondell and Affiliates of Millennium and Occidental

   Both Lyondell and Millennium Petrochemicals entered into separate asset
contribution agreements on December 1, 1997, providing for the contribution of
the Lyondell and Millennium contributed businesses. Wholly owned subsidiaries
of Occidental (the "Occidental Subsidiaries") entered into an asset
contribution agreement with Equistar on May 15, 1998, with respect to the
transfer of the Occidental contributed business, a portion of which transfer
was accomplished through a merger of an Occidental Subsidiary with and into
Equistar. Among other things, the asset contribution agreements required
representations and warranties by the contributor regarding the transferred
assets and indemnification of Equistar by the contributor. These agreements
also provide for the assumption by Equistar of, among other things

  . third-party claims that are related to preclosing contingent liabilities
    that are asserted before December 1, 2004, as to Lyondell and Millennium
    Petrochemicals or before May 15, 2005, as to the Occidental Subsidiaries,
    to the extent the aggregate amount does not exceed, in the case of each
    of Lyondell, Millennium and the Occidental Subsidiaries, $7 million

  . third-party claims related to preclosing contingent liabilities that are
    asserted for the first time after December 1, 2004, as to Lyondell and
    Millennium Petrochemicals or after May 15, 2005, as to the Occidental
    Subsidiaries

  . obligations for $745 million of Lyondell indebtedness, a portion of which
    was since repaid

  . a $750 million intercompany obligation of Millennium Petrochemicals to an
    indirect subsidiary of Millennium, which was since repaid

  . the lease intended for security relating to the Corpus Christi facility
    contributed by Occidental, which was since repaid

  . liabilities for products sold after December 1, 1997, as to Lyondell and
    Millennium Petrochemicals or after May 15, 1998, as to the Occidental
    Subsidiaries, regardless of when manufactured

  . in the case of each of the Lyondell and Millennium Petrochemicals asset
    contribution agreements, unfunded health care and life insurance post-
    retirement benefits related to the applicable contributed business or to
    former Lyondell employees

  . in the case of the Millennium Petrochemicals asset contribution
    agreement, future maintenance and maintenance turnaround costs related to
    the Millennium contributed business

  . in the case of each of the Millennium Petrochemicals and Occidental asset
    contribution agreements, obligations under railcar leases under which
    Equistar is the lessee

   Lyondell, Millennium Petrochemicals and the Occidental Subsidiaries entered
into Master Intellectual Property Agreements and other related agreements with
respect to intellectual property with Equistar. These agreements provide for
all of the following

  . the transfer of intellectual property of Lyondell, Millennium
    Petrochemicals and the Occidental Subsidiaries related to the businesses
    each contributed to Equistar

  . rights and licenses to Equistar with respect to intellectual property
    retained by Lyondell, Millennium Petrochemicals or the Occidental
    Subsidiaries that was not solely related to the business of Equistar but
    is useful in that business

  . rights and licenses from Equistar to Lyondell, Millennium Petrochemicals
    and the Occidental Subsidiaries with respect to intellectual property
    transferred to Equistar that Lyondell, Millennium Petrochemicals and the
    Occidental Subsidiaries may use in connection with their other businesses

                                       79
<PAGE>

   Lyondell, Millennium Petrochemicals and the Occidental Subsidiaries each
entered into various other conveyance documents with Equistar to effect their
asset contributions as provided for in their respective contribution
agreements.

 Loans by Millennium and Occidental

   In May 1998, in connection with Occidental's entry into Equistar, Equistar
executed promissory notes to Millennium in the principal amount of $75.0
million and to Occidental in the principal amount of $419.7 million. Each of
the notes provided for the annual accrual of interest based on a year of 360
days and actual days elapsed at an interest rate equal to LIBOR plus 0.6%.
These notes were paid in full in June 1998 with borrowings under Equistar's
bank $500 million credit facility and $1.25 billion revolving credit facility.

 Loan by Equistar to Lyondell

   In December 1997, Lyondell's subsidiary that is a limited partner in
Equistar executed a promissory note to Equistar in the principal amount of $345
million as part of its capital contribution to Equistar. The note provided for
the annual accrual of interest based on a year of 360 days at a rate of LIBOR
plus 0.5%. Lyondell had the right to prepay any portion of the principal and
interest due without penalty or premium. This note was repaid in full in July
1998, and the proceeds were distributed to Lyondell and Millennium.

 Transactions with Lyondell Methanol

   Equistar provides operating and other services for Lyondell Methanol under
the terms of existing agreements that were assumed by Equistar from Lyondell,
including the lease to Lyondell Methanol by Equistar of the real property on
which its methanol plant is located. Under the terms of those agreements,
Lyondell Methanol pays Equistar a management fee of $6 million per year and
will reimburse some expenses of Equistar at cost. Equistar sells natural gas to
Lyondell Methanol at prices generally representative of Equistar's cost.
Lyondell Methanol purchased natural gas in the amounts of $44 million for 1998
and $4 million for December 1997. All of the foregoing agreements with Lyondell
Methanol are expected to continue on terms similar to those described above.

 Transactions with LYONDELL-CITGO Refining

   In connection with the formation of Equistar, Lyondell's rights and
obligations under the terms of its product sales and raw material purchase
agreements with LYONDELL-CITGO Refining were assigned to Equistar. Accordingly,
refinery products, including propane, butane, naphthas, heating oils and gas
oils, are sold by LYONDELL-CITGO Refining to Equistar as raw materials, and
some olefins by-products are sold by Equistar to LYONDELL-CITGO Refining for
processing into gasoline. Net payments from LYONDELL-CITGO Refining to Equistar
in connection with these product sales and raw material purchase agreements
were $92 million for 1998 and $1 million for December 1997.

   Equistar and LYONDELL-CITGO Refining are also parties to

  . tolling arrangements under which some of LYONDELL-CITGO Refining's
    coproducts are transmitted to Equistar and processed by Equistar, with
    the resulting product being returned to LYONDELL-CITGO Refining

  . terminaling and storage obligations

  . agreements for Equistar to perform some marketing services for LYONDELL-
    CITGO Refining

   Aggregate payments under these various services agreements of $15 million
were made by LYONDELL-CITGO Refining to Equistar with respect to 1998. No
payments were made for December 1997.

                                       80
<PAGE>

   All of the agreements between LYONDELL-CITGO Refining and Equistar are on
terms generally representative of prevailing market prices. All of the
foregoing agreements with LYONDELL-CITGO Refining are expected to continue on
terms similar to those described above.

 Services and Shared-Site Agreements with Lyondell and Affiliates of Millennium
 and Occidental

   Lyondell has agreed to provide some types of corporate, general and
administrative services to Equistar, including legal, treasury, risk
management, tax services and employee benefit plan administration. Equistar has
also agreed to provide services to Lyondell, including health, safety and
environmental services, human resource services, information services and legal
services. Depending on the nature of the services, a fixed price may be paid or
costs reimbursed. As a consequence of services being provided by Equistar to
Lyondell and by Lyondell to Equistar, a net payment is made by Equistar to
Lyondell of approximately $90,000 per month. These service agreements are
expected to continue on terms substantially similar to those described above.

   Equistar and Millennium Petrochemicals have entered into a variety of
operating, manufacturing and technical service agreements related to the
business of Equistar and the vinyl acetate monomer, acetic acid, synthesis gas
and methanol businesses retained by Millennium Petrochemicals. These agreements
include the provision by Equistar to Millennium Petrochemicals of materials
management, utilities, fuelstreams, office space, health, safety and
environmental services and computer services. These agreements also include the
provision by Millennium Petrochemicals to Equistar of operational services,
including waste water treatment, fuelstreams and barge dock access and
services. As a consequence of services being provided by Equistar to Millennium
Petrochemicals and by Millennium Petrochemicals to Equistar, net payments were
made by Millennium Petrochemicals to Equistar of $5 million with respect to
1998. No payments were made for December 1997. In the case of product sales,
prices are generally market-related. In the case of services, prices are
usually based on an allocation of costs according to anticipated relative
usage. Equistar also purchases relatively small amounts of vinyl acetate
monomer from Millennium Petrochemicals. Millennium Petrochemicals purchases
relatively small amounts of hydrogen and natural gas from Equistar. Except for
modifications resulting from Millennium Petrochemicals' recent sale of its
synthesis gas and methanol businesses, these service and product sales
agreements are expected to continue on terms similar to those described above.

   On May 15, 1998, Occidental Chemical and Equistar entered into an operating
agreement under which Occidental Chemical agreed to operate and maintain the
Occidental contributed business and to cause third parties to continue to
provide equipment, products and commodities in connection with the Occidental
contributed business upon substantially the same terms and conditions as
provided before the transfer of the Occidental contributed business. Under the
terms of the operating agreement, Equistar agreed to reimburse Occidental
Chemical for its costs in connection with the services provided to Equistar and
to pay Occidental Chemical an administrative fee. The operating agreement
terminated according to its terms on June 1, 1998. During the term of the
operating agreement, Equistar paid Occidental Chemical an administrative fee of
$1 million in connection with the services Occidental Chemical rendered to
Equistar under the agreement.

   On June 1, 1998, Occidental Chemical and Equistar entered into a transition
services agreement. Under the terms of the transition services agreement,
Occidental Chemical agreed to provide to Equistar services in connection with
the transferred businesses, including services related to accounting, payroll,
office administration, marketing, transportation, purchasing and procurement,
management, human resources, customer service and technical services. In
consideration for the services provided by Occidental Chemical under the
agreement, depending on the service, Equistar is required to either

  . pay Occidental Chemical a fixed fee for their services according to the
    terms of the transition services agreement

  . reimburse Occidental Chemical for all reasonable, direct, out-of-pocket
    costs that are incurred by Occidental Chemical in connection with
    providing their services


                                       81
<PAGE>

The transition services agreement provides that the parties must mutually agree
as to which payment option they wish to use. Between June 1, 1998 and December
31, 1998, Equistar paid Occidental Chemical $6 million in connection with
services provided under the agreement. The transition services agreement
expires by its terms on June 1, 1999.

   Equistar and Occidental Chemical have entered into a toll processing
agreement, dated as of May 15, 1998, whereby Equistar has retained the services
of Occidental Chemicals's facilities in Ashtabula, Ohio, for the processing of
Glycol Ether TM into Glycol Ether TM Borate Ester material for brake or clutch
fluid. Under the terms of the agreement, Equistar procures from Occidental
Chemical its total requirements of Glycol Ether TM Borate Ester, up to a
maximum of 1 million pounds, in any calendar quarter. The agreement requires
Occidental Chemical to process Glycol Ether TM into Glycol Ether TM Borate
Ester exclusively for Equistar. The fee for the processing is $0.35 per pound
of Glycol Ether TM Borate Ester until April 30, 1999. After April 30, 1999, the
fee may be adjusted based on a price index according to the terms of the
agreement. Between May 15, 1998 and December 31, 1998, Equistar paid Occidental
Chemical $124,000 under the agreement. The initial term of the agreement ends
on December 31, 2001, but will continue from year to year unless terminated
effective December 31 of the relevant year by either party upon at least 12
months' written notice.

 Occidental Ethylene Sales Agreement

   Equistar and Occidental Chemical entered into an ethylene sales agreement,
dated May 15, 1998. Under the terms of the ethylene sales agreement with
Occidental Chemical, Occidental Chemical has agreed to purchase an annual
minimum amount of ethylene from Equistar equal to 100% of the ethylene raw
material requirements of Occidental Chemical's United States plants. The
ethylene raw material is exclusively for internal use in production at these
plants less any quantities up to 250 million pounds tolled according to the
provisions of the agreement. Internal use in production is estimated to be 2
billion pounds per year at the time of signing the agreement.

   Equistar's maximum supply obligation in any calender year under the ethylene
sales agreement with Occidental Chemical is 2.55 billion pounds. Upon three
years' notice from either party to the other, the ethylene sales agreement with
Occidental Chemical may be "phased down." No phase down may commence before
January 1, 2009. According to the phase-down provisions of the agreement, the
annual minimum requirements specified in the agreement must be phased down over
at least a five-year period.

   The ethylene sales agreement with Occidental Chemical provides that each
month Occidental Chemical will pay a price approximately equal to Equistar's
quarterly quantity weighted-average net ethylene final transaction price for
sales to third parties. Between May 15, 1998 and December 31, 1998, Equistar
received aggregate payments from Occidental Chemical of $171 million under the
ethylene sales agreement.

 Other Product Sales to Related Parties

   Ethylene Sales Agreement with Millennium Petrochemicals. Equistar sells
ethylene to Millennium Petrochemicals at market-related prices under an
agreement entered into in connection with the formation of Equistar. Under this
agreement with Millennium Petrochemicals, Millennium Petrochemicals is required
to purchase 100% of its ethylene requirements for its La Porte, Texas facility,
estimated at 300 million pounds per year, up to a maximum of 330 million pounds
per year. Millennium Petrochemicals has the option to increase the amount
purchased up to 400 million pounds per year beginning January 1, 2001. The
initial term of the contract expires December 1, 2000. The contract
automatically renews annually. Either party may terminate on one year's notice.
If Millennium Petrochemicals elects to increase its purchases under the
contract, however, a party must provide two years' notice of termination. The
pricing terms under this agreement between Equistar and Millennium
Petrochemicals are similar to the ethylene sales agreement. Millennium
Petrochemicals paid $40 million to Equistar for ethylene for 1998. Millennium
Petrochemicals paid $5 million to Equistar for ethylene for December 1997.

   Ethylene Sales Agreement with Lyondell. Lyondell has purchased ethylene and
propylene from Equistar since its formation on price terms comparable to those
of the ethylene sales agreement. Lyondell paid $21 million to Equistar for
ethylene for 1998. Lyondell paid $3 million to Equistar for ethylene for
December 1997. Lyondell paid $29 million to Equistar for propylene for 1998 and
$4 million to Equistar for propylene for December 1997. Lyondell and Equistar
contemplate entering into agreements concerning sales by Equistar to Lyondell
of ethylene, propylene, benzene, ethylene oxide and methanol. In the case of
ethylene, propylene, benzene and ethylene oxide, the contracts are expected to
be requirements contracts, less amounts Lyondell is required to purchase under
outstanding agreements, at market-related prices. A wholly owned subsidiary of
Lyondell licenses MTBE technology to Equistar. This subsidiary also purchases a
significant portion of the MTBE produced by Equistar at one of its two
Channelview units at market-related prices.

 Related Party Leases

   Equistar subleases office space for its headquarters and administrative
functions from Lyondell. Equistar paid $5 million for the office space for
1998. Equistar paid $234,000 for the office space for December 1997. Millennium
Petrochemicals subleases administrative office space from Equistar. Millennium
Petrochemicals paid $504,000 for 1998. Millennium Petrochemicals paid $42,000
for December 1997 under the sublease agreement.

 Agreement Regarding Services of Equistar's Chief Executive Officer

   Dan F. Smith serves as the Chief Executive Officer of both Lyondell and
Equistar and is a director of Lyondell. Mr. Smith receives no compensation from
Equistar. Under an agreement between Equistar and Lyondell, Equistar pays
Lyondell a monthly amount in respect of Mr. Smith's services. In 1998, Equistar
paid Lyondell $1.2 million. In December 1997, Equistar paid Lyondell $100,000.
After December 31, 1998, Equistar will pay an amount equal to 125% of Eugene
Allspach's estimated cash compensation as compensation to Lyondell for the
services rendered by Mr. Smith. See "Management--Members of the Partnership
Governance Committee, Executive Officers of Equistar and Directors and
Executive Officers of Equistar Funding" and "Compensation."

 Indemnity Agreement with Occidental Chemical

   Equistar and Occidental Chemical have entered into an indemnity agreement
pursuant to which Occidental Chemical agrees to contribute to Equistar an
amount equal to up to the lesser of $419.7 million or the principal amount of
the notes due 2009 then outstanding, together with interest. Occidental
Chemical is only required to pay this amount to Equistar if the holders of the
notes due 2009 have not been able to obtain payment after the holders of the
notes due 2009 have pursued and exhausted all their remedies to compel payment
by Equistar and Equistar Funding, including the liquidation of assets. The
indemnity expressly does not create any right in the holders of the notes due
2009 or any person other than Occidental Chemical, Equistar and the partners in
Equistar. The indemnity may be terminated without the consent of the holders of
the notes due 2009.

   The indemnity will remain in effect indefinitely, but at any time after June
14, 2005, Occidental Chemical may elect to terminate the indemnity if all of
the following conditions exist:

  . Equistar's ratio of total indebtedness to total capitalization is, as of
    the most recently completed fiscal quarter, lower than the same ratio for
    the 12-month period ending December 31, 1998

  . Equistar's ratio of earnings before interest, taxes, depreciation and
    amortization to net interest for the most recent 12-month period is at
    least 105% of the same ratio for the 12-month period ending December 31,
    1998

  . Equistar is not then in default in the payment of principal of, or
    interest on, any indebtedness for borrowed money in excess of $15 million

                                       83
<PAGE>

  . Equistar is not then in default in respect of any covenants, other than
    those relating to payment of principal and/or interest, relating to any
    indebtedness for borrowed money if the effect of a default shall be to
    accelerate, or to permit the holder or obligee of such indebtedness, or
    any trustee on behalf of a holder or obligee, to accelerate, with or
    without the giving of notice or lapse of time or both, the indebtedness
    in an aggregate amount in excess of $50 million

   In addition, if Occidental GP, Occidental LP1 and Occidental LP2 sell all of
their respective interests in Equistar to an unaffiliated third party at any
time, or if Occidental Chemical Holding Corporation sells all of its interests
in Occidental GP, Occidental LP1 and Occidental LP2, Occidental Chemical may
elect to terminate its indemnity, if, at the time of the sale or termination,
Equistar has an investment grade credit rating or the fair market value of
Equistar's assets is at least 140% of the gross amount of its liabilities.

   If Occidental sells its interest in Equistar, Occidental may terminate the
indemnity if Equistar has an investment grade credit rating or the fair market
value of Equistar's assets is at least 140% of the gross amount of its
liabilities.

   Occidental Chemical may assign its rights or obligations under the indemnity
to Occidental at any time without the consent of Equistar. Following such an
assignment, Occidental Chemical may terminate the indemnity at any time if
Equistar ceases to be an affiliate of Occidental.

                              The Exchange Offers

   We are offering to exchange our outstanding 8 1/2% notes due 2004 for a like
principal amount of our new 8 1/2% notes due 2004 and our outstanding 8 3/4%
notes due 2009 for a like principal amount of our new 8 3/4% notes due 2009.
The offers to exchange our 8 1/2% notes and our 8 3/4% notes are separate,
independent offers. We may extend, delay or terminate one offer without
extending, delaying or terminating the other offer. The description of the
exchange offers contained in this prospectus applies to both our offer to
exchange the 8 1/2% notes and our offer to exchange the 8 3/4% notes. However,
holders of either series of outstanding notes will need to complete the
exchange offer documentation related to that particular series. Holders of both
the 8 1/2% notes and the 8 3/4% notes wishing to exchange both series of notes
will need to complete two separate sets of exchange offer documents.

Purpose and Effect of the Exchange Offers

   In connection with the sale of outstanding notes, we entered into an
exchange and registration rights agreement with the initial purchasers of the
outstanding notes. In the exchange and registration rights agreement, we agreed
to file a registration statement relating to both of our offers to exchange the
outstanding 8 1/2% notes for new 8 1/2% notes and the outstanding 8 3/4% notes
for new 8 3/4% notes. We also agreed to use our reasonable best efforts to
complete both of the offers within 180 days after February 16, 1999. We are
offering the new notes under this prospectus to satisfy those obligations under
the exchange and registration rights agreement.

   However, the SEC has recently proposed the repeal of its interpretations
permitting the use of a registration statement in connection with exchange
offers such as ours. We cannot predict whether the SEC will act on this
proposal before completion of the exchange offers. If those interpretations are
repealed before the exchange offers are completed, holders of outstanding notes
will not be able to receive new notes under the exchange offers. Rather, we
will be required to register the outstanding notes under a shelf registration
statement, in connection with resales by the holders. Holders will be required
to deliver a prospectus to the purchasers and will be subject to civil
liability provisions under the Securities Act in connection with their resales.

   We will file with the SEC a shelf registration statement to cover resales of
either, or both, series of outstanding notes if any of the following occur

  . any changes in law or applicable interpretations by the staff of the SEC
    do not permit us to effect the exchange offers as contemplated by the
    exchange and registration rights agreement

  . any outstanding notes validly tendered under the exchange offers are not
    exchanged for new notes within 180 days after February 16, 1999

  . any initial purchaser so requests with respect to the outstanding notes
    not eligible to be exchanged for new notes in the exchange offers

  . any applicable law or interpretations do not permit any holder of
    outstanding notes to participate in the exchange offers

  . any holder of outstanding notes that participates in the exchange offers
    does not receive freely transferable new notes in exchange for tendered
    outstanding notes

  . we so elect

   If we are required to file a shelf registration statement, we will use our
reasonable best efforts to cause the SEC to declare effective the shelf
registration statement. We will also use our reasonable best efforts to keep
the shelf registration statement effective for up to two years after February
16, 1999. We will have the ability to suspend the shelf registration statement
for no more than (a) 45 days during the first 12-month period after February
16, 1999, and (b) 90 days during any subsequent 12-month period (a "Suspension
Period"), if we

                                       85
<PAGE>

determine, in our reasonable best judgment upon written advice of counsel, that
continued effectiveness would require disclosure of confidential information or
interfere with any financing, acquisition, reorganization or other material
transaction involving Equistar.

   If we fail to comply with deadlines for completion of either or both of the
exchange offers, we will be required to pay additional interest to holders of
the outstanding notes. Please read the section captioned "The Exchange and
Registration Rights Agreement" for more details regarding the exchange and
registration rights agreement.

   To exchange an outstanding note for transferable new notes in one or both of
the exchange offers, you will be required to make all of the following
representations

  . any new notes you receive will be acquired in the ordinary course of
    business

  . you have no arrangement or understanding with any person to participate
    in the distribution of the outstanding notes or the new notes within the
    meaning of the Securities Act

  . you are not our "affiliate," as defined in Rule 405 of the Securities
    Act, or, if you are our affiliate, you will comply with the registration
    and prospectus delivery requirements of the Securities Act to the extent
    applicable

  . if you are not a broker-dealer, you are not engaged in, and do not intend
    to engage in, the distribution of the new notes

  . if you are a broker-dealer that will receive new notes in exchange for
    outstanding notes acquired for your own account as a result of market-
    making activities or other trading activities, you will deliver a
    prospectus meeting the requirements of the Securities Act in connection
    with any resale of the new notes.

Resale of New Notes

   Based on interpretations of the SEC staff in "no action letters" issued to
third parties, we believe that each new note issued under each of the exchange
offers may be offered for resale and be resold and otherwise transferred by the
holder of that new note without compliance with the registration and prospectus
delivery provisions of the Securities Act if

  . you are not our "affiliate" within the meaning of Rule 405 under the
    Securities Act

  . the new notes are acquired in the ordinary course of your business

  . you do not intend to participate in the distribution of new notes and
    have no arrangement or understanding with any person or entity to
    participate in a distribution of the new notes

However, the SEC has not considered either of our exchange offers in the
context of a no-action letter, and there can be no assurance that the staff of
the SEC would make a similar determination with respect to either of our
exchange offers as in other circumstances.

   If you tender in one or both of the exchange offers with the intention of
participating in any manner in a distribution of the new notes, you

  . cannot rely on these interpretations in no-action letters by the SEC
    staff

  . must comply with the registration and prospectus delivery requirements of
    the Securities Act -including being named as selling noteholders-in
    connection with a secondary resale transaction

   Unless an exemption from registration is otherwise available, any
securityholder intending to distribute new notes should be covered by an
effective registration statement under the Securities Act containing the
selling security holder's information required by Item 507 of Regulation S-K
under the Securities Act. This prospectus may be used for an offer to resell,
resale or other retransfer of new notes of either series only as

                                       86
<PAGE>

specifically described in this prospectus. Only broker-dealers that acquired
the outstanding notes as a result of market-making activities or other trading
activities may participate in the exchange offers. Failure to comply with these
requirements could result in liability for which you are not indemnified by us.
Please read the section captioned "Plan of Distribution" for more details
regarding the transfer of new notes.

Terms of the Exchange Offers

   Upon the terms and subject to the conditions described in this prospectus
and in the applicable letter of transmittal, we will accept for exchange any
outstanding notes properly tendered and not withdrawn before the expiration
date for either exchange offer. We will issue $1,000 principal amount of new
notes in exchange for each $1,000 principal amount of outstanding notes
surrendered under the exchange offers. Outstanding notes may be tendered only
in integral multiples of $1,000. No exchange offer for notes of a series is
conditioned upon any minimum aggregate principal amount of outstanding notes of
that series being tendered for exchange. One exchange offer is not dependent
upon the consummation of the other exchange offer.

   As of the date of this prospectus, $300 million aggregate principal amount
of 8 1/2% notes due 2004 and $600 million aggregate principal amount of 8 3/4%
notes due 2009 are outstanding. This prospectus and the applicable letter of
transmittal are being sent to all registered holders of outstanding notes.
There will be no fixed record date for determining registered holders of
outstanding notes entitled to participate in either of the exchange offers.

   We intend to conduct the exchange offers according to the provisions of the
exchange and registration rights agreement, the applicable requirements of the
Securities Act and the Securities Exchange Act of 1934 and the rules and
regulations of the SEC. Outstanding notes that are not tendered for exchange in
the exchange offers

  . will remain outstanding

  . will continue to accrue interest

  . will be entitled to the rights and benefits the holders have under the
    indenture relating to the notes and the exchange and registration rights
    agreement

   We will be deemed to have accepted for exchange properly tendered
outstanding notes when we have given oral or written notice of the acceptance
to the exchange agent and complied with the applicable provisions of the
exchange and registration rights agreement. The exchange agent will act as
agent for the tendering holders for the purposes of receiving the new notes.

   If you tender outstanding notes in an exchange offer, you will not be
required to pay brokerage commissions or fees or, subject to the instructions
in the letter of transmittal, transfer taxes with respect to the exchange of
outstanding notes. We will pay all charges and expenses, other than some
applicable taxes as described below, in connection with both of the exchange
offers. It is important for holders to read the section labeled "--Fees and
Expenses" for more details regarding fees and expenses incurred in the exchange
offers.

   We will return any outstanding notes that we do not accept for exchange for
any reason without expense to the tendering holder as promptly as practicable
after the expiration or termination of the applicable exchange offer.

   In addition, we reserve the right in our sole discretion to (i) purchase or
make offers for any outstanding notes that remain outstanding subsequent to the
applicable expiration date and (ii) to the extent permitted by applicable law,
purchase outstanding notes in the open market, in privately negotiated
transactions or otherwise. The terms of any such purchases or offers may differ
from the terms of the applicable exchange offer.

Expiration Date

   Each exchange offer will expire at 12:00 midnight, New York City time, on
Monday, October 4, 1999, unless, in our sole discretion, we extend it.

                                       87
<PAGE>

Extensions, Delay in Acceptance, Termination or Amendment

   We expressly reserve the right, at any time or at various times, to extend
the period of time during which an exchange offer for notes of a series is
open. We may extend that period for each series independently. During any
extensions, all outstanding notes of that series you have previously tendered
will remain subject to the exchange offer for that series, and we may accept
them for exchange.

   To extend an exchange offer, we will notify the exchange agent orally or in
writing of any extension. We will also make a public announcement of the
extension no later than 9:00 a.m., New York City time, on the next business day
after the previously scheduled expiration date.

   If any of the conditions described below under "--Conditions to the Exchange
Offers" have not been satisfied, we reserve the right, in our sole discretion
to

  . delay accepting for exchange any outstanding notes of that series

  . extend either or both of the exchange offers

    or

  . terminate either or both of the exchange offers

by giving oral or written notice of a delay, extension or termination to the
exchange agent. Subject to the terms of the exchange and registration rights
agreement, we also reserve the right to amend the terms either or both of the
exchange offers in any manner.

   Any delay in acceptance, extension, termination or amendment will be
followed as promptly as practicable by oral or written notice to the registered
holders of outstanding notes of the series affected. If we amend an exchange
offer in a manner we determine to constitute a material change, we will
promptly disclose the amendment by means of a prospectus supplement and, if
required, a post-effective amendment to the registration statement. We will
distribute the supplement or the post-effective amendment to the registered
holders of the outstanding notes of the series affected. Depending upon the
significance of the amendment and the manner of disclosure to the registered
holders, we will extend an exchange offer if the exchange offer would otherwise
expire during that period.

   Without limiting the manner in which we may choose to make public
announcements of any delay in acceptance, extension, termination or amendment
of either or both of the exchange offers, we will have no obligation to
publish, advertise or otherwise communicate any public announcement, other than
by making a timely release to the Dow Jones News Service.

Conditions to the Exchange Offers

   Despite any other term of either of the exchange offers, if in our
reasonable judgment either of the exchange offers, or the making of any
exchange by a holder of outstanding notes of a series, would violate applicable
law or any applicable interpretation of the staff of the SEC

  . we will not be required to accept for exchange, or exchange any new notes
    for, any outstanding notes of a series

  . we may terminate either or both of the exchange offers as provided in
    this prospectus before accepting any outstanding notes for exchange

In addition, we will not be obligated to accept for exchange the outstanding
notes of any holder that has not made

  . the representations described under "--Purpose and Effect of the Exchange
    Offers," "--Procedures for Tendering" and "Plan of Distribution"

                                       88
<PAGE>

  . other representations as may be reasonably necessary under applicable SEC
    rules, regulations or interpretations to make available to us an
    appropriate form for registration of the new notes under the Securities
    Act

   We expressly reserve the right to amend or terminate either or both of the
exchange offers, and to reject for exchange any outstanding notes not
previously accepted for exchange, upon the occurrence of any of the conditions
to the exchange offers specified above. We will give oral or written notice of
any extension, amendment, nonacceptance or termination to the holders of the
outstanding notes of the series affected as promptly as practicable.

   These conditions are for our sole benefit, and we may assert them or waive
them in whole or in part at any time or at various times in our sole
discretion. If we fail at any time to exercise any of these rights, this
failure will not mean that we have waived our rights. Each right will be deemed
an ongoing right that we may assert at any time or at various times.

   In addition, we will not accept for exchange any outstanding notes tendered,
and will not issue new notes in exchange for any outstanding notes tendered, if
at that time any stop order has been threatened or is in effect with respect to
(1) the registration statement of which this prospectus is a part or (2) the
qualification of the indenture relating to the notes under the Trust Indenture
Act of 1939.

Procedures for Tendering

 How to Tender Generally

   Only a holder of outstanding notes may tender their outstanding notes in an
exchange offer. To tender in either or both of the exchange offers, a holder
must either (1) comply with the procedures for manual tender or (2) comply with
the automated tender offer program procedures of DTC described below under "--
Tendering Through DTC's Automated Tender Offer Program."

   To complete a manual tender, you must

  . complete, sign and date the letter of transmittal or a facsimile of the
    letter of transmittal

  . have the signature on the letter of transmittal guaranteed if the letter
    of transmittal so requires

  . mail or delivery of the letter of transmittal or facsimile to the
    exchange agent before the expiration date; and

  . deliver the outstanding notes to be tendered to the exchange agent with
    the applicable letter of transmittal prior to the expiration date or make
    book-entry delivery of the outstanding notes to the exchange agent, in
    which case the exchange agent must receive, before the expiration date, a
    timely confirmation of book-entry transfer of the outstanding notes into
    the exchange agent's account at DTC according to the procedure for book-
    entry transfer described below

To be tendered effectively, the exchange agent must receive any physical
delivery of the applicable letter of transmittal and other required documents
at its address provided above under "Prospectus Summary--The Exchange Agent"
before the expiration date. The tender by a holder that is not withdrawn before
the expiration date and our acceptance of that tender will constitute an
agreement between the holder and us according to the terms and subject to the
conditions described in this prospectus and in the applicable letter of
transmittal.

   If you wish to tender your outstanding notes and cannot comply with the
requirement to deliver the letter of transmittal and your outstanding notes or
use the automated tender offer program of DTC before the expiration date, you
must tender your outstanding notes according to the guaranteed delivery
procedures described below.

   The method of delivery of outstanding notes, the applicable letter of
transmittal and all other required documents to the exchange agent is at the
holder's election and risk. Delivery will be deemed made only when actually
received or confirmed by the exchange agent unless we indicate otherwise.
Rather than mail these items, we recommend that holders use an overnight or
hand delivery service. In all cases, holders should allow sufficient time to
assure delivery to the exchange agent before the

                                       89
<PAGE>

expiration date. Holders should not send the applicable letter of transmittal
or outstanding notes to us. Holders may request their broker-dealers,
commercial banks, trust companies or other nominees to effect the above
transactions on their behalf.

 Tendering Through DTC's Automated Tender Offer Program

   The exchange agent and DTC have confirmed that any financial institution
that is a participant in DTC's system may use DTC's automated tender offer
program to tender outstanding notes of either series. Participants in the
program may, instead of physically completing and signing the applicable letter
of transmittal and delivering it to the exchange agent, transmit their
acceptance of an exchange offer electronically. They may do so by causing DTC
to transfer the outstanding notes to the exchange agent according to its
procedures for transfer. DTC will then send an agent's message to the exchange
agent.

   The term "agent's message" means a message transmitted by DTC, received by
the exchange agent and forming part of the book-entry confirmation, stating
that

  . DTC has received an express acknowledgment from a participant in its
    automated tender offer program that is tendering outstanding notes that
    are the subject of book-entry confirmation

  . the participant has received and agrees to be bound by the terms of the
    applicable letter of transmittal or, in the case of an agent's message
    relating to guaranteed delivery, that the participant has received and
    agrees to be bound by the applicable notice of guaranteed delivery

  . the agreement may be enforced against the participant

 How to Tender if You Are a Beneficial Owner

   If you beneficially own outstanding notes of either series that are
registered in the name of a broker-dealer, commercial bank, trust company or
other nominee and you wish to tender those notes, you should contact the
registered holder as soon as possible and instruct it to tender on your behalf.
If you are a beneficial owner and wish to tender on your own behalf, you must,
before completing and executing the applicable letter of transmittal and
delivering your outstanding notes, either

  . make appropriate arrangements to register ownership of the outstanding
    notes in your name

  . obtain a properly completed bond power from the registered holder of your
    outstanding notes

The transfer of registered ownership may take considerable time and may not be
completed before the expiration date.

 Signatures and Signature Guarantees

   You must have signatures on the applicable letter of transmittal or a notice
of withdrawal described below guaranteed by one of the following:

  . a member firm of a registered national securities exchange

  . a member of the National Association of Securities Dealers, Inc.

  . a commercial bank or trust company having an office or correspondent in
    the United States

  . an "eligible guarantor institution" within the meaning of Rule 17Ad-15
    under the Securities Exchange Act of 1934

The above "eligible institutions" must be a member of one of the recognized
signature guarantee programs identified in the applicable letter of
transmittal, unless the outstanding notes are tendered

  . by a registered holder who has not completed the box entitled "Special
    Issuance Instructions" or "Special Delivery Instructions" on the
    applicable letter of transmittal, and the new notes are being

                                       90
<PAGE>

    issued directly to the registered holder of the outstanding notes
    tendered in the exchange for those new notes

  . for the account of an eligible institution

 When Endorsements or Bond Powers are Needed

   If the applicable letter of transmittal is signed by a person other than
the registered holder of any outstanding notes, the outstanding notes must be
endorsed or accompanied by a properly completed bond power. The bond power
must be signed by the registered holder as the registered holder's name
appears on the outstanding notes. An eligible institution must guarantee the
signature on the bond power.

   If the applicable letter of transmittal or any outstanding notes or bond
powers are signed by trustees, executors, administrators, guardians,
attorneys-in-fact, officers of corporations or others acting in a fiduciary or
representative capacity, those persons should so indicate when signing. They
should also submit evidence of their authority to deliver the letter of
transmittal satisfactory to us unless we waive this requirement.

 Determinations Under the Exchange Offers

   We will determine in our sole discretion all questions as to the validity,
form, eligibility, time of receipt, acceptance of tendered outstanding notes
and withdrawal of tendered outstanding notes. Our determination will be final
and binding. We reserve the absolute right to reject any outstanding notes not
properly tendered or any outstanding notes our acceptance of which would, in
the opinion of our counsel, be unlawful. We also reserve the right to waive
any defects, irregularities or conditions of the exchange offer as to
particular notes. Our interpretation of the terms and conditions of the
exchange offers, including the instructions in the applicable letter of
transmittal, will be final and binding on all parties.

   Unless waived, any defects or irregularities in connection with tenders of
outstanding notes of either series must be cured within the time we shall
determine. Neither we, the exchange agent nor any other person will be under
any duty to give notification of defects or irregularities with respect to
tenders of outstanding notes, and none of the aforementioned will incur
liability for failure to give notification. Tenders of outstanding notes will
not be deemed made until any defects or irregularities have been cured or
waived. Any outstanding notes received by the exchange agent that are not
properly tendered and the defects or irregularities of which have not been
cured or waived will be returned to the tendering holder, unless otherwise
provided in the applicable letter of transmittal, as soon as practicable
following the expiration date.

 When We Will Issue New Notes

   In all cases, we will issue new notes for outstanding notes that we have
accepted for exchange under the exchange offers only after the exchange agent
timely receives both

  . outstanding notes or a timely book-entry confirmation of the outstanding
    notes into the exchange agent's account at DTC

  . a properly completed and duly executed letter of transmittal and all
    other required documents or a properly transmitted agent's message

 Return of Outstanding Notes Not Accepted or Exchanged

   If we do not accept any tendered outstanding notes for exchange for any
reason described in the terms and conditions of the exchange offers or if
outstanding notes are submitted for a greater principal amount than the holder
desires to exchange, the unaccepted or nonexchanged outstanding notes will be
returned without expense to their tendering holder. In the case of outstanding
notes tendered by book-entry transfer into the exchange agent's account at DTC
according to the procedures described below, the non-exchanged outstanding
notes will be credited to an account maintained with DTC. These actions will
occur as promptly as practicable after the expiration or termination of the
applicable exchange offer.

                                      91

Book-Entry Transfer

   The exchange agent will make a request to establish an account with respect
to the outstanding 8 1/2% notes and the outstanding 8 3/4% notes at DTC for
purposes of the exchange offers promptly after the date of this prospectus. Any
financial institution participating in DTC's system may make book-entry
delivery of outstanding notes by causing DTC to transfer the outstanding notes
into the appropriate account maintained by the exchange agent at DTC according
to DTC's procedures for transfer. If you are unable to deliver confirmation of
the book-entry tender of their outstanding notes into the exchange agent's
account at DTC or all other documents required by the applicable letter of
transmittal to the exchange agent on or before the applicable expiration date
must tender their outstanding notes according to the guaranteed delivery
procedures described below.

Withdrawal of Tenders

   Except as otherwise provided in this prospectus, you may withdraw your
tender at any time before 12:00 midnight, New York City time, on the applicable
expiration date unless previously accepted for exchange. For a withdrawal to be
effective either

  . the exchange agent must receive a written notice of withdrawal at one of
    the addresses listed above under "Prospectus Summary--The Exchange Agent"

  . the withdrawing holder must comply with the appropriate procedures of
    DTC's automated tender offer program system

Any notice of withdrawal must comply with all of these requirements:

  . specify the name of the person who tendered the outstanding notes to be
    withdrawn

  . identify the outstanding notes to be withdrawn, including the series,
    registration number or numbers and the principal amount of the
    outstanding notes

  . be signed by the person who tendered the outstanding notes in the same

    transfer sufficient to permit the trustee for the outstanding notes to
    register the transfer into the name of the person withdrawing the tender

  . specify the name in which the outstanding notes are to be registered, if
    different from that of the person who tendered the outstanding notes

If outstanding notes have been tendered under the procedure for book-entry

notes and otherwise comply with the procedures of DTC.

   Equistar will determine all questions as to the validity, form, eligibility

be final and binding on all parties. Equistar will deem any outstanding notes
so withdrawn not to have been validly tendered for exchange for purposes of an
exchange offer.

   Any outstanding notes that have been tendered for exchange but are not
exchanged for any reason will be returned to their holder without cost to the
holder, or, in the case of outstanding notes tendered by book-entry transfer
into the exchange agent's account at DTC according to the procedures described
above, the outstanding notes will be credited to an account maintained with DTC
for the outstanding notes. This return or crediting will take place as soon as
practicable after withdrawal, rejection of tender or termination of the
applicable exchange offer. Holders may retender properly withdrawn outstanding
notes by following one of the procedures described under the caption "--
Procedures for Tendering" above at any time on or before the expiration date.

Fees and Expenses

   We will bear the expenses of soliciting tenders. The principal solicitation
is being made by mail; however, we may make additional solicitation by
telegraph, telephone or in person by our officers and regular employees and the
officers and regular employees of our affiliates.

   We have not retained any dealer-manager in connection with either exchange
offer and will not make any payments to broker-dealers or others soliciting
acceptances of either exchange offer. We will, however, pay the exchange agent
reasonable and customary fees for its services and reimburse it for its related
reasonable out-of-pocket expenses. We may also pay brokerage houses and other
custodians, nominees and fiduciaries the reasonable out-of-pocket expenses
incurred by them in forwarding copies of this prospectus, letter of transmittal
and related documents to the beneficial owners of the outstanding notes and in
handling or forwarding tenders for exchange of both series.

   We will pay the cash expenses to be incurred in connection with the exchange
offers, including

  . SEC registration fees

  . fees and expenses of the exchange agent and trustee

  . accounting and legal fees and printing costs

  . related fees and expenses

Transfer Taxes

   We will pay all transfer taxes, if any, applicable to the exchange of
outstanding notes under an exchange offer. The tendering holder, however, will
be required to pay any transfer taxes, whether imposed on the registered holder
or any other person, if

  . certificates representing new notes or outstanding notes for principal
    amounts not tendered or accepted for exchange are to be delivered to, or
    are to be issued in the name of, any person other than the registered
    holder of outstanding notes tendered

  . tendered outstanding notes are registered in the name of any person other
    than the person signing the letter of transmittal

  . a transfer tax is imposed for any reason other than the exchange of
    outstanding notes under an exchange offer.

If satisfactory evidence of payment of any transfer taxes payable by a note
holder is not submitted with the letter of transmittal, the amount of the
transfer taxes will be billed directly to that tendering holder.

Consequences of Failure to Exchange

   If you do not exchange your outstanding notes for new notes under either or
both of the exchange offers you will remain subject to the existing
restrictions on transfer of the outstanding notes. In general, you may not
offer or sell the outstanding notes unless they are registered under the
Securities Act or if the offer or sale is exempt from registration under the
Securities Act and applicable state securities laws. Except as required by the
exchange and registration rights agreement, we do not intend to register
resales of the outstanding notes under the Securities Act. Based on
interpretations of the SEC staff, holders may offer for resale, or may resell
or otherwise transfer new notes issued in the exchange offers without
compliance with the registration and prospectus delivery provisions of the
Securities Act, if they

  . are not our "affiliate" within the meaning of Rule 405 under the
    Securities Act

  . acquired the new notes in the ordinary course of their business

                                       94
<PAGE>

  . have no arrangement or understanding with respect to the distribution of
    the new notes to be acquired in the exchange offers

   If a holder tenders in the exchange offers for the purpose of participating
in a distribution of the new notes, it

  . cannot rely on the applicable interpretations of the SEC

  . must comply with the registration and prospectus delivery requirements of
    the Securities Act in connection with a secondary resale transaction

Accounting Treatment

   We will not recognize a gain or loss for accounting purposes upon the
consummation of an exchange offer. We will amortize expenses of both of the
exchange offers over the term of the new notes of the applicable series under
generally accepted accounting principles.

Other

   Participation in the exchange offers is voluntary, and you should carefully
consider whether to accept. You are urged to consult your financial and tax
advisors in making your own decision on what action to take.

                          Description of the New Notes

General

   The new notes will be issued, and the outstanding notes were issued, under
an indenture dated January 15, 1999, that we entered into with The Bank of New
York, as trustee. We supplemented the indenture to establish the terms of the
notes. The terms of the notes include those stated in the indenture, the
supplemental indentures and those made part of the indenture by the Trust
Indenture Act of 1939, as amended. The Indenture does not limit the aggregate
principal amount of securities that can be issued thereunder and does not limit
our right to issue additional notes of any series at any time.

   We have summarized below material selected provisions of the notes and the
indenture, as supplemented. For a complete description, you should refer to the
indenture and the notes filed as exhibits to this registration statement which
includes this prospectus. See "Available Information." Capitalized terms used
in this summary are defined below under "--Definitions Used in This Description
of New Notes."

   The outstanding 8 1/2% notes and the new 8 1/2% notes will constitute a
single class of debt securities under the indenture. The outstanding 8 3/4%
notes and the new 8 3/4% notes will constitute a separate single class of debt
securities under the indenture. If the exchange offers contemplated by this
prospectus are consummated, holders of the applicable series of outstanding
notes who do not exchange those notes for new notes in the exchange offers will
vote together with holders of new notes for all relevant purposes under the
indenture. Accordingly, when determining whether the required holders have
given any notice, consent or waiver or taken any other action permitted under
the indenture, any outstanding notes that remain outstanding after the exchange
offers will be aggregated with the applicable series of new notes. All
references herein to specified percentages in aggregate principal amount of a
series of notes outstanding shall be deemed to mean, at any time after the
exchange offers are consummated, percentages in aggregate principal amount of a
series of outstanding notes and the applicable series of new notes then
outstanding.

   The form and term of the new notes are the same as the form and term of the
outstanding notes they will replace, except that

  . we will register the new notes under the Securities Act

  . the new notes, once registered, will not bear legends restricting
    transfer

  . holders of the new notes will not be entitled to some rights under the
    exchange and registration rights agreement, including our payment of
    additional interest for failure to meet specified deadlines, which
    terminate when the exchange offers are consummated

The new notes will be issued solely in exchange for an equal principal amount
of outstanding notes. As of the date of this prospectus, $300 million aggregate
principal amount of 8 1/2% notes and $600 million aggregate principal amount of
8 3/4% notes are outstanding. See "The Exchange Offers."

Ranking of the New Notes

   The outstanding notes are, and the new notes will

  . be senior unsecured indebtedness of Equistar and Equistar Funding

  . rank equal in right of payment with any outstanding notes that are not
    exchanged and with all of our existing and future unsecured and
    unsubordinated indebtedness; Equistar currently has approximately $1.3
    billion of unsecured and unsubordinated indebtedness

  . rank senior to any future subordinated indebtedness

   We may not incur additional debt that is senior to the notes; however the
new notes will effectively be subordinated to any secured debt that we may be
permitted to incur under the covenants of the indenture for the notes to the
extent of the collateral for the secured debt; currently we have no secured
debt.

                                       96
<PAGE>

Maturity and Interest of the New Notes

   The 8 1/2% notes will mature on February 15, 2004. The 8 3/4% notes will
mature on February 15, 2009. Interest on both the outstanding 8 1/2% notes and
the outstanding 8 3/4% notes began to accrue on February 16, 1999. We will

  . pay interest semiannually on February 15 and August 15 of each year,
    beginning August 15, 1999

  . pay interest to the person registered as owner of the notes on the
    February 1 or August 1 preceding the interest payment date

  . compute interest based on a 360-day year consisting of twelve 30-day
    months

   Holders of new notes on the relevant record date for the first interest
payment date following the consummation of the applicable exchange offer will
receive interest accruing from the most recent date to which interest has been
paid on the outstanding notes. Outstanding notes accepted for exchange will
cease to accrue interest from and after the date of consummation of the
applicable exchange offer. Holders whose outstanding notes are accepted for
exchange will not receive any payment in respect of accrued interest on such
outstanding notes otherwise payable on any interest payment date the record
date for which occurs on or after the consummation of the applicable exchange
offer.

Optional Redemption of the New Notes

   At any time, we may redeem any or all of either series of new notes. We will
pay a redemption price equal to the greater of the principal amount of the
series of notes being redeemed or, as determined by a Quotation Agent, the sum
of the present values of the remaining scheduled payments of principal and
interest on the series of notes to be redeemed discounted to the date of
redemption on a semiannual basis, assuming a 360-day year consisting of twelve
30-day months at the Adjusted Treasury Rate. We will also pay accrued but
unpaid interest.

   Notice of redemption will be mailed between 30 and 60 days before the
redemption date to each holder of the new notes to be redeemed. Interest will
cease to accrue on the new notes or the portions of the new notes called for
redemption on and after the redemption date unless we default in payment of the
redemption price.

Covenants Restricting Equistar's Actions Contained in the Indenture for the New
Notes

   We have agreed to two principal restrictions on our activities for the
benefit of the holders of the outstanding notes and the new notes. In the
description of these covenants, all references to "us" or "our" mean Equistar
Chemicals, LP and any of its Subsidiaries, unless the context clearly indicates
otherwise.

 Limitation on Liens

   We have agreed that Equistar will not, and will not permit any Restricted
Subsidiary to, issue, assume or guarantee any indebtedness for borrowed money
secured by any liens upon any Restricted Subsidiary unless we secure the notes
equally and ratably with or prior to the other indebtedness secured by the
lien. This covenant has exceptions that permit each of

  . liens affecting property of a corporation existing at the time it becomes
    a Subsidiary or at the time it is merged into or consolidated with
    Equistar

  . liens on property existing at the time of its acquisition or incurred to
    secure payment of all or part of its purchase price or to secure debt
    incurred before, at the time of or within 24 months after its acquisition
    for the purpose of financing all or part of the purchase price

  . liens on our property existing on the date of the indenture

  . liens on any property to secure all or part of the cost of construction
    or improvements on that property or debt incurred to provide funds for
    any such liens in a principal amount not exceeding the cost of the
    construction or improvements

                                       97
<PAGE>

  . liens which secure only an indebtedness owed to us by a Subsidiary

  . liens in favor of the United States or any state within the United
    States, or any department, agency, instrumentality, or political
    subdivision of any U.S. jurisdiction to secure partial progress, advance
    or other payments under any contract or statute or to secure any
    indebtedness incurred for the purpose of financing all or any part of the
    purchase price or cost of constructing or improving the property subject
    thereto, including, without limitation, liens to secure debt of the
    pollution control or industrial revenue bond type

  . liens required by any contract or statute to permit our performance of
    any contract or subcontract made by us with or at the request of the
    United States of America, any state or any department, agency or
    instrumentality or political subdivision of either the United States or
    any state

  . any extension, renewal or replacement, or successive extensions, renewals
    or replacements, in whole or in part, of any lien referred to in the
    foregoing exceptions or of any debt secured thereby, provided that the
    principal amount of debt secured thereby shall not exceed the greater of
    the following

    -- the principal amount of debt so secured

    -- the fair market value of the underlying property or assets to which
      that lien relates at the time of the extension, renewal or replacement

    and provided that the extension, renewal or replacement lien shall be
    limited to all or part of substantially the same property which secured
    the lien extended, renewed or replaced, including improvements on the
    property

If Equistar so determines, it may also equally and ratably secure any other
indebtedness or other obligation then existing and any other indebtedness or
obligation created after that time.

   Notwithstanding the foregoing provisions of "--Limitation on Liens,"
Equistar and any one or more Restricted Subsidiaries may issue, assume or
guarantee debt secured by liens, that would otherwise be subject to the
foregoing restrictions if the sum of

  . the aggregate principal amount of such secured debt

  . the aggregate outstanding principal amount of all of other debt of
    Equistar and the Restricted Subsidiaries, not including debt permitted to
    be secured under the exceptions described above, which would otherwise be
    subject to the foregoing restrictions

  . the aggregate Value of the Sale and Leaseback Transactions in existence
    at that time, not including Sale and Leaseback Transactions as to which
    Equistar has complied with paragraph B of "--Limitation on Sale and
    Leaseback Transactions"

do not at any one time exceed 15% of the Consolidated Net Tangible Assets of
Equistar and its consolidated Subsidiaries.

 Limitation on Sale and Leaseback Transactions

   We have agreed that Equistar will not, and will not permit any Restricted
Subsidiary to, enter into any Sale and Leaseback Transactions with any person
unless at least one of the following applies:

  A. Equistar or the Restricted Subsidiary would be entitled, under "--
     Limitation on Liens," to incur debt in a principal amount equal to or
     exceeding the Value of the Sale and Leaseback Transaction, secured by a
     lien on the property to be leased, without equally and ratably securing
     the notes

  B. Within four months after the effective date of the Sale and Leaseback
     Transaction, whether made by Equistar or a Restricted Subsidiary,
     Equistar applies to the voluntary retirement of Funded Debt an amount
     equal to the Value of the Sale and Leaseback Transaction, less the
     principal amount of notes delivered, within four months after the
     effective date of the arrangements, to the trustee for retirement and
     cancellation and the principal amount of other Funded Debt voluntarily
     retired within that four-month period, excluding retirements of notes
     and other Funded Debt as a result of conversions or under mandatory
     sinking fund or prepayment provisions or by payment at maturity

                                       98
<PAGE>

Events of Default Under the New Notes

   Each of the following is an event of default with respect to the notes

  . our failure to pay interest on the notes for 30 days

  . our failure to pay principal or premium on the notes

  . our failure to observe or perform any other covenant or agreement in the
    indenture for 60 days after written notice by the trustee or by the
    holders of at least 25% in aggregate principal amount of the outstanding
    debt securities under the indenture affected thereby

  . bankruptcy, insolvency or reorganization events

   If an event of default with respect to notes occurs and is continuing,
either the trustee or the holders of at least 25% in aggregate principal amount
of the outstanding notes or, if applicable, 25% in aggregate principal amount
of the outstanding debt securities affected thereby, may declare the principal
of and the accrued but unpaid interest immediately due and payable. At any time
after a declaration of acceleration with respect to notes has been made, but
before a judgment or decree for payment of money has been obtained by the
trustee, the holders of a majority in aggregate principal amount of the notes
may rescind the acceleration and its consequences if they comply with specified
conditions.

   The holders of a majority in aggregate principal amount of the outstanding
debt securities under the indenture with notice to the trustee, have the right
to waive existing or past defaults under the indenture except that they may not
waive

  . an existing or past default on the payment or the principal on, or
    premium, if any, or interest on any additional amounts relating to taxes,
    assessments or other governmental charges, or

  . a continued default that the indenture requires the consent of all
    effected holders to waive without the consent of each holder effected.

   The indenture provides that, subject to the duty of the trustee during
default to act with the required standard of care, the trustee is under no
obligation to exercise any of its rights or powers under the indenture at the
request or direction of any holders, unless such holders offer reasonable
indemnity to the trustee. As long as the requirements concerning
indemnification are satisfied, the holders of a majority in aggregate principal
amount of the outstanding affected debt securities under the indenture have the
right in most cases to direct the time, method and place of conducting any
proceeding for any remedy available to the trustee under the indenture or
exercising any trust or power conferred on the trustee.

   We are required to give the trustee a certificate stating whether or not we
are in default under the indenture and, if so, specifying all defaults and the
nature of all defaults every year.

Indenture Requirements Relating to Consolidation, Merger and Sale of Assets

   We have agreed that each of Equistar and Equistar Funding will not
consolidate with or merge into, or sell, assign, transfer, lease, convey or
otherwise dispose of, all or substantially all of its assets, to anyone unless
each of the following conditions is satisfied:

  . immediately after giving effect to the transaction, no default or event
    of default will have happened and be continuing

  . either Equistar or Equistar Funding shall be the continuing partnership
    or corporation, as applicable, or the successor is

    --organized under the laws of the United States, one of the states of
     the United States or the District of Columbia

     and

                                       99
<PAGE>

    --assumes by supplemental indenture all our obligations under the
     indenture and the notes

  . we deliver to the trustee an officer's certificate and opinion of counsel
    stating that the transaction complies with these conditions

Modification and Waiver of the Indenture

   We and the trustee may amend or supplement the indenture with the consent of
the holders of not less than a majority in aggregate principal amount of all
series of outstanding debt securities that are issued under the indenture and
affected by the amendment or supplement. Without the consent of the holder of
each outstanding note, we may not

  . reduce the principal or premium or change the stated maturity of the
    principal or premium of any note

  . reduce the amount of debt securities under the indenture, the holders of
    which must consent to an amendment or supplement to the indenture

  . make any change in the percentage of principal amount of debt securities
    under the indenture necessary to modify or waive any default

  . reduce the rate of or change the time for payment of interest on any note

  . impair the right to institute suit for the enforcement of any payment on
    any note

   The holders of a majority in aggregate principal amount of outstanding notes
affected by a covenant have the right to waive Equistar's compliance with some
of the covenants contained in the indenture.

   We and the trustee may modify and amend the indenture without the consent of
any holder of notes

  . to evidence a successor obligor under the indenture

  . to add covenants or events of default for the benefit of the holders

  . to secure the debt securities under the indenture

  . to establish the form or terms of debt securities under the indenture

  . to provide for the acceptance of appointment by a successor trustee or
    facilitate the administration of the trusts under the indenture by more
    than one trustee

  . to cure any ambiguity or inconsistency in the indenture, provided such
    modification or amendment does not adversely affect in any material
    respect the interests of the holders of the notes

  . to supplement any of the provisions of the indenture to the extent
    necessary to permit or facilitate defeasance and discharge of any series
    of notes, provided such modification or amendment does not adversely
    affect in any material respect the interests of the holders of the notes

  . to make any other change that does not adversely affect the rights of any
    holder

Defeasance and Covenant Defeasance Under the Indenture

   The indenture provides that we may elect either

  . to defease and be discharged from any and all obligations with respect to
    all or a portion of the notes of any series (legal defeasance) except for
    the obligations

    --to register the transfer or exchange of notes

    --to replace temporary, mutilated, destroyed, lost or stolen notes of
     the series

    --to maintain an office or agency in respect of the series of notes

                                      100
<PAGE>

    --to hold moneys for payment in trust

    or

  . to be released from our obligations with respect to restrictive and other
    covenants, and any omission to comply with these obligations will not
    constitute a default or an event of default with respect to the notes
    (covenant defeasance)

In either case, upon our irrevocable deposit with the trustee, or other
qualifying trustee, in trust, of

  . an amount in cash

  . government obligations that, through the payment of principal and
    interest according to their terms, will provide money in an amount

    or

  . a combination of the above

The amount deposited must be sufficient to pay the principal of and premium, if
any, on and interest, if any, to stated maturity, or redemption, on the notes,
on the scheduled due dates.

   We are required to deliver to the trustee an opinion of counsel stating that
the holders of these notes proposed to be defeased will not recognize income,
gain or loss for United States federal income tax purposes as a result of legal
defeasance or covenant defeasance. The opinion must also state that holders
will be subject to United States federal income tax on the same amounts, in the
same manner and at the same times as would have been the case if legal
defeasance or covenant defeasance had not occurred. The opinion, in the case of
legal defeasance, must refer to and be based upon a ruling of the Internal
Revenue Service or a change in applicable United States federal income tax law
occurring after the date of the indenture.

Payment Under the Indenture for the New Notes

   We are required to maintain an office or agency in each payment location for
the notes and may from time to time designate additional offices or agencies at
which the principal of and premium, if any, on and interest, if any, on the
notes will be payable. Payments will be made in New York City, and we will
initially designate the office of the agent of the trustee in New York City as
an office where the principal, premium and interest will be payable. We reserve
the option to pay interest, if any, on the notes either by

  . check mailed to the registered holder at their address

  . wire transfer to an account located inside the United States maintained
    by the registered holder.

We may designate additional offices or agencies, approve a change in the
location of any office or agency and, except as provided above, rescind the
designation of any office or agency at any time.

   Moneys we pay to the trustee or a paying agent for the payment of principal,
premium, if any, or interest, if any, on any note that remains unclaimed for
two years after the principal, premium or interest becomes due and payable will
be repaid to us. After that time, the holder of the note, subject to applicable
abandoned property or similar laws, will be an unsecured general creditor and
may look only to us for payment.

Transfer and Exchange of the New Notes

   Subject to the terms of the indenture, notes may be presented for
registration of transfer and for exchange either

  . at each office or agency required to be maintained by us for payment of
    each series, as described under "--Payment Under the Indenture for the
    New Notes"

  . at each other office or agency that we may designate from time to time

Registration of transfers and exchanges will be effected if the transfer agent
is satisfied with the evidence of ownership and identity of the holder making
the request and if the transfer form is duly executed. No service

                                      101
<PAGE>

charge will be made for any registration of transfer or exchange of notes, but
we may require you to pay any tax or other governmental charge incurred in
connection with the transfer or exchange.

   In the event of any redemption in whole or in part, we will not be required

  . to register the transfer of or exchange new notes of any series during a
    period beginning at the opening of business 15 days before any selection
    of notes of that series to be redeemed and ending at the close of
    business on the date the relevant notice of redemption is mailed

  . to register the transfer of or exchange of any note or portion of any
    note called for redemption, except the unredeemed portion, if any, of a
    note being redeemed in part

  . to register the transfer of or exchange of any note that has been
    surrendered for repayment at the option of the holder, except the
    portion, if any, of the note not to be so repaid

Limited Recourse

   Our ability to make payments on the new notes is solely dependent upon
Equistar's ability to generate sufficient cash from operations. If Equistar or
Equistar Funding fails to fulfill its obligations under the new notes or the
indenture, you will not have the right to recover against any of Equistar's
partners, whether as a general partner or limited partner or otherwise, or
against the partners' respective parents or other affiliates. You are not a
beneficiary of and have no right to enforce any of the arrangements between
Equistar and its partners and their affiliates.

   Equistar Funding is a wholly owned subsidiary of Equistar. The new notes
will be joint and several obligations of Equistar and Equistar Funding.
However, Equistar Funding will have little or no revenues or assets that could
be used to satisfy its obligations under the new notes. As a result, you will
be required as a practical matter to look only to Equistar to satisfy the
obligations under the new notes.

Definitions Used in This Description of New Notes

   We have provided below a summary of capitalized terms used in this summary
description of the notes. The indenture contains the full definition of all
these terms.

   "Adjusted Treasury Rate" means, with respect to any redemption date, the
rate per annum equal to the semiannual equivalent yield to maturity of the

or to any other person, other than Equistar or a Subsidiary, to which funds

   "Subsidiary" means any corporation in which at least a majority of the

                       Federal Income Tax Considerations

   The following summary fairly describes the material United States federal
income tax consequences expected to apply to the exchange of outstanding notes
for new notes. This summary is based upon the provisions of the Internal
Revenue Code of 1986, as amended, the final, temporary and proposed regulations
promulgated under the Internal Revenue Code, and administrative rulings and
judicial decisions now in effect. All of the above are subject to change or to
different interpretations, possibly with retroactive effect. This discussion is
for general information only and does not purport to address all of the
possible federal income tax consequences or any other federal, or any state,
local or foreign, tax consequences of the acquisition, ownership and
disposition of the outstanding notes or new notes. It is limited to investors
who hold the outstanding notes and the new notes as capital assets and does not
address the federal income tax consequences that may be relevant to particular
investors in light of their unique circumstances or to particular investors,
such as dealers in securities, insurance companies, financial institutions,
foreign corporations, partnerships or trusts, nonresident alien individuals,
and tax-exempt entities, who may be subject to special treatment under the
federal income tax law.

   An exchange of the outstanding notes for the new notes under the exchange
offers will not constitute a taxable event for federal income tax purposes. As
a result, holders who exchange their outstanding notes for new notes will not
recognize in income any accrued and unpaid interest on the new notes by reason
of the exchange. An exchanging holder will have the same adjusted basis and
holding period in the new notes as it had in the outstanding notes immediately
before the exchange.

   Holders should consult their own tax advisor as to the particular tax
consequences for them of exchanging outstanding notes for new notes in the
exchange offers, including the applicability and effect of any state, local, or
foreign tax laws and or recent or possible future changes in the tax laws.

                 The Exchange and Registration Rights Agreement

   In connection with the issuance of the outstanding notes, we entered into an
exchange and registration rights agreement. Under the exchange and registration
rights agreement, we agreed to

  . file a registration statement with the SEC on or within 60 days after
    February 16, 1999

  . use our reasonable best efforts to cause the registration statement to be
    declared effective under the Securities Act within 150 days after
    February 16, 1999

  . use our reasonable best efforts to cause the exchange offers to be
    consummated within 180 days after February 16, 1999

  . keep the exchange offers open for acceptance for a period of not less
    than 30 calendar days after the date notice of the exchange offers is
    mailed to holders of the outstanding notes

  . accept for exchange all outstanding notes duly tendered and not validly
    withdrawn under the exchange offers according to the terms of the
    registration statement and letter of transmittal

   As soon as practicable after the exchange offer registration statement
becomes effective, we will offer the holders of outstanding notes who are not
prohibited by any law or policy of the SEC from participating in these exchange
offers the opportunity to exchange their outstanding notes for exchange notes
registered under the Securities Act that are substantially identical to the
outstanding notes, except that the exchange notes will not contain terms with
respect to transfer restrictions, registration rights and additional interest.

   The exchange and registration rights agreement also provides that we

  . shall make available for a period of 180 days after the consummation of
    the exchange offers a prospectus meeting the requirements of the
    Securities Act to any broker-dealer for use in connection with any resale
    of any new notes

                                      104
<PAGE>

  . shall pay all expenses incident to the exchange offers, including the
    expense of one counsel to the holders of the notes, and will indemnify
    some holders of the notes, including any broker-dealer, against
    liabilities including liabilities under the Securities Act

   A broker-dealer that delivers a prospectus to purchasers in connection with
resales will be subject to various civil liability provisions under the
Securities Act and will be bound by the provisions of the exchange and
registration rights agreement, including some of the indemnification rights and
obligations.

   We will use our reasonable best efforts to file with the SEC a shelf
registration statement to cover resales of the outstanding notes by those
holders who provide required information in connection with that shelf
registration statement if

  . any changes in law, SEC rules or regulations or applicable
    interpretations of these laws, rules or regulations by the staff of the
    SEC do not permit us to effect the exchange offers as contemplated by the
    exchange and registration rights agreement

  . the exchange offers are not consummated within 180 days after February
    16, 1999

  . any initial purchaser of the outstanding notes so requests but only with
    respect to any outstanding notes acquired directly by them

  or

  . any holder of the outstanding notes notifies us that it is not permitted
    to participate in the exchange offers or would not receive fully
    tradeable new notes in the exchange offers

We will use our reasonable best efforts to keep the shelf registration
statement, if filed, effective for a period of two years after February 16,
1999. We have the ability to suspend the shelf registration statement for no
more than

  . 45 days during the first 12-month period after February 16, 1999,

    and

  . 90 days during any subsequent 12-month period

if we determine, in our reasonable best judgment upon the written advice of
counsel, that continued effectiveness would require disclosure of confidential
information or would interfere with any financing, acquisition, reorganization
or other material transaction involving Equistar.

   If a registration default occurs, we will be obligated to pay additional
interest to each holder of outstanding notes at a rate equal to 0.25% per
annum. If this registration default is not cured within 90 days, the interest
rate increases to 0.50% per annum. A registration defaults occurs if

  . the registration statement is not filed with the SEC within 60 days of
    February 16, 1999

  . the registration statement or shelf registration statement is not
    declared effective within 150 days of February 16, 1999

  . the exchange offers are not consummated within 180 days of February 16,
    1999

  . the shelf registration statement is filed and declared effective within
    180 days of February 16, 1999, but subsequently ceases to be effective

Following the cure of a registration default, additional interest will cease to
accrue. Additional interest does not accrue during a suspension period.

   If you desire to tender your outstanding notes, you will be required to make
to us the representations described under "The Exchange Offers--Purpose and
Effect of the Exchange Offers" and "The Exchange Offers--Procedures for
Tendering" to participate in the exchange offers. In addition, we may require
you to deliver information to be used in connection with the shelf registration
statement to have your notes included in

                                      105
<PAGE>

the shelf registration statement and to benefit from the provisions regarding
additional interest described in the preceding paragraphs. A holder who sells
outstanding notes under the shelf registration statement generally will be
required to be named as a selling security holder in the related prospectus and
to deliver a prospectus to purchasers. A holder will also be subject to the
civil liability provisions under the Securities Act in connection with the
sales and will be bound by the provisions of the exchange and registration
rights agreement that are applicable to a holder, including indemnification
obligations.

   The description of the exchange and registration rights agreement contained
in this section is a summary of the terms we believe are material at this time
and is qualified in its entirety by reference to all provisions of the exchange
and registration rights agreement. The exchange and registration statement is
filed as an exhibit to the registration statement of which this prospectus is a
part.

                         Book-Entry; Delivery and Form

   The new notes will initially be represented by one or more permanent global
notes in definitive, fully registered book-entry form (the "Global Notes") that
will be registered in the name of Cede & Co., as nominee of DTC. The Global
Notes will be deposited, on behalf of the acquirors of the new notes
represented thereby, with a custodian for DTC for credit to the respective
accounts of the acquirors or to such other accounts as they may direct at DTC.
See "The Exchange Offers--Book-Entry Transfer."

The Global Notes

   We expect that under procedures established by DTC

  . upon deposit of the Global Notes with DTC or its custodian, DTC will
    credit on its internal system a portion of the Global Notes that shall be
    composed of the corresponding respective amounts of the Global Notes to
    the respective accounts of persons who have accounts with the depository

  . ownership of the notes will be shown on, and the transfer or ownership
    will be effected only through, records maintained by DTC or its nominee,
    with respect to interests and records of participants and with respect to
    interests of persons other than participants

   So long as DTC or its nominee is the registered owner of the Global Notes,
DTC or its nominee, as the case may be, will be considered the sole owner or
holder of the notes represented by the Global Notes for all purposes under the
indenture. Except as provided below, owners of beneficial interests in Global
Notes will not

  . be entitled to have notes represented by Global Notes registered in their
    names

  . receive or be entitled to receive physical delivery of certificated notes

  . be considered the owners or holders of the Global Notes under the
    indenture for any purpose, including with respect to the giving of any
    direction, instruction or approval to the trustee

   Payments of the notes represented by Global Notes will be made to DTC or its
nominee, as the registered owner. None of Equistar, Equistar Funding, the
trustee or the paying agent will have any responsibility or liability for any
aspect of the records relating, to or payments made on account of, beneficial
ownership interest in the Global Notes or for maintaining, supervising or
reviewing any records relating to beneficial ownership interest under the
indenture.

   We expect that DTC or its nominees, upon receipt of any payment on the notes
represented by the Global Notes, will credit participants' accounts with
payments in amounts proportionate to their respective beneficial interest in
the Global Notes as shown in the records of DTC or its nominee. We also expect
that participants will be governed by standing instructions and customary
practice as is now the case with securities held for the accounts of customers
registered in the names of nominees for the customers. Payment will be the
responsibility of the participants.

                                      106
<PAGE>

   Transfers between participants in DTC will be effected according to DTC's
procedures and will be settled in same-day funds. Transfers between
participants in Euroclear or Cedel will be effected in the ordinary way
according to their respective rules and operating procedures. If a holder
requires physical delivery of a certificated security for any reason, including
to sell notes to persons in states that require physical delivery of the
security or to pledge the security, a holder must transfer its interest in the
Global Notes according to the normal procedures of DTC, Euroclear or Cedel and
the procedures in the indenture.

   Subject to compliance with the transfer restrictions applicable to the
notes, cross-market transfers between the participants in DTC, on the one hand,
and Euroclear or Cedel participants, on the other hand, will be effected
through DTC according to DTC's rules on behalf of Euroclear or Cedel, as the
case may be, by its respective depositary. Cross-market transactions will
require delivery of instructions to Euroclear or Cedel, as the case may be, by
the counter party in that system according to the rules and procedures and
within the established deadlines, in Brussels time, of such system if the
transaction meets its settlement requirements. Euroclear or Cedel, as the case
may be, will deliver instructions to its respective depositary to take action
to effect final settlement on its behalf by delivering or receiving interests
in the relevant Global Notes in DTC and making or receiving payment according
to normal procedures for same-day funds settlement applicable to DTC. Euroclear
participants and Cedel participants may not deliver instructions directly to
the depostaries for Euroclear or Cedel.

   Because of time zone differences, the securities account of Euroclear or
Cedel participants purchasing an interest in a Global Note from a participant
in DTC will be credited, and any crediting will be reported to the relevant
Euroclear or Cedel participant during the note settlement processing day
immediately following the settlement date of DTC. The note settlement day must
be a business day for Euroclear and Cedel. Cash received in Euroclear or Cedel
as a result of sales of interest in a Global Note by or through a Euroclear or
Cedel participant to a participant in DTC will be received with value on the
settlement date of DTC but will be available in the relevant Euroclear or Cedel
cash amount only as of the business day for Euroclear or Cedel following DTC's
settlement date.

   Although DTC, Euroclear and Cedel have agreed to the foregoing procedures to
facilitate transfers of interests in the Global Notes among participants in
DTC, Euroclear and Cedel it is under no obligation to perform or to continue to
perform procedures, and procedures may be discontinued at any time. Neither we
nor the trustee will have any responsibility for the performance by DTC,
Euroclear and Cedel or their respective participants or indirect participants
of their respective obligations under the rules and procedures governing their
operations.

Description of DTC

   The description of the operations and procedures of DTC is provided below
solely as a matter of convenience. These operations and procedures are solely
within the control of the respective settlement systems and are subject to
change by them from time to time. Neither we nor the initial purchasers takes
any responsibility for these operations or procedures, and investors are urged
to contact the relevant system or its participants directly to discuss these
matters.

   DTC has advised that it is

  . a limited purpose trust company organized under the laws of the State of
    New York

  . a "banking organization" within the meaning of the New York Banking Law

  . a member of the Federal Reserve System

  . a "clearing corporation" within the meaning of the Uniform Commercial
    Code, as amended

  . a "clearing agency" registered under Section 17A of the Securities
    Exchange Act of 1934, as amended

                                      107
<PAGE>

   DTC was created to hold securities for its participants and facilitates the
clearance and settlement of securities transactions between participants
through electronic book-entry changes to the accounts of its participants,
thereby eliminating the need for physical transfer and delivery of
certificates.

   DTC's participants include securities brokers and dealers, including the
initial purchasers, banks and trust companies, clearing corporations as well as
other organizations. Indirect access to DTC's system is also available to other
entities such as banks, brokers, dealers and trust companies that clear through
or maintain a custodial relationship with a participant, either directly or
indirectly. Investors who are not participants may beneficially own securities
held by or on behalf of DTC only through participants or indirect participants.

Certificated Notes

   Interest in the Global Notes may be exchanged for certificated securities if

  . we notify the trustee in writing that DTC is no longer willing or able to
    act as a depositary or DTC ceases to be registered as a clearing agency
    under the Exchange Act and a successor depositary is not appointed within
    90 days of notice or cessation

  . we, at our option, notify the trustee in writing that we elect to cause
    the issuance of notes in certificated form under the indenture

  . other events occur as provided in the indenture

Upon the occurrence of any of the events described in the preceding sentence,
we will cause the appropriate certificated securities to be delivered.

   Neither Equistar, Equistar Funding nor the trustee shall be liable for any
delay by DTC or any participant or indirect participant in identifying the
beneficial owners of the related notes, and each person may conclusively rely
on, and shall be protected in relying on, instructions from DTC for all
purposes, including with respect to the registration and delivery, and the
respective principal amounts, of the notes to be issued.

             Summary Description of Other Indebtedness of Equistar

$1.25 Billion Revolving Credit Facility

   In connection with its formation on December 1, 1997, Equistar entered into
a $1.25 billion revolving credit facility expiring November 2002 with
Millennium America Inc., as guarantor, Bank of America National Trust and
Savings Association and The Chase Manhattan Bank, as agents, and a syndicate of
lending banks which varies from time to time. The syndication provisions of the
facility permit a lender, with the consent of Equistar (so long as Equistar is
not in default), to assign all or a portion of its interests, rights and
obligations under the facility, subject to specified dollar limitations.
Assignments to another lender under the facility or to an affiliate of the
assigning lender do not require Equistar's consent. This facility was amended
in February 1999. Borrowings under the $1.25 billion revolving credit facility
currently bear interest depending on the type of borrowing made by Equistar, at
its option, at one of the following:

  . LIBOR, generally the London interbank market rate, or NIBOR, generally
    the New York interbank market rate, plus, in each case, an applicable
    margin and facility fee based on Equistar's long-term debt ratings as
    established by S&P's and Moody's. For example, at Equistar's long-term
    debt ratings as of May 31, 1999, the applicable margin was 0.375% and the
    facility fee was 0.125%. The margin and facility fee each increase
    incrementally for each level of downgrade in long-term debt rating.

  . a base rate of either the Federal Funds rate plus 0.5% or a fixed rate of
    interest offered by a lender

  . a rate established by competitive bids submitted by the sponsoring banks
    through a competitive auction feature

The $1.25 billion revolving credit facility is available for working capital
and general purposes as needed.

   The $1.25 billion revolving credit facility limits Equistar's ability to
incur liens to secure indebtedness, enter into sale and leaseback transactions,
and to allow subsidiaries to have indebtedness or preferred stock. In general,
Equistar can only have liens to secure indebtedness, enter into sale and
leaseback transactions, and allow our material subsidiaries to have
indebtedness or preferred stock, to the extent the sum of those amounts does
not exceed the greater of

  . $250 million

     or

  . 15% of Equistar's consolidated net tangible assets as shown on the most
    recent audited consolidated balance sheet

   In addition to the quantitative basket allowance described above, the $1.25
billion revolving credit facility allows Equistar to incur or permit to exist
specified categories of liens, such as

  . liens securing the performance of bids and contracts

  . liens that arise by operation of law

  . tax liens

  . liens on an asset incurred within 180 days of acquisition or construction
    of the asset

  . pre-existing liens

   The $1.25 billion revolving credit facility also permits a material
subsidiary to issue indebtedness or preferred stock to Equistar or another
material subsidiary and allows material subsidiaries to have indebtedness for
obligations for the purchase price of real property or equipment and pre-
existing indebtedness.

   Under the covenants of the $1.25 billion revolving credit facility, Equistar
may not permit the following ratio to exceed 0.6 to 1.0

  . the difference of (a) total indebtedness, not including specified types
    of subordinated loans from the partners of Equistar, minus (b) all cash
    and cash equivalents on our consolidated balance sheet in excess of $25
    million

     to

  . the sum of (1) the amount from the foregoing bullet point and (2) total
    partners' equity

   Under the covenants of the $1.25 billion revolving credit facility, we may
not permit the ratio of

  . ""EBITDA," defined in the $1.25 billion revolving credit facility as the
    sum of operating income, amortization, depreciation and depletion, and
    noncash compensation expense

     to

  . net interest expense

for any period of four consecutive fiscal quarters ended on a date listed below
to be less than the amount listed opposite the applicable date:

In the event that Equistar incurs downtime at a plant, the $1.25 billion
revolving credit facility provides that up to two times during the entire term
of the facility, but only for one quarter during any four consecutive fiscal
quarters, we may have the right to add to EBITDA the lesser of (1) the
estimated amount by which EBITDA is impacted by that downtime or (2) $20
million.

   The $1.25 billion revolving credit facility also provides that Equistar may
not consolidate or merge with another person or permit another person to merge
into Equistar, without showing that

  . no event of default has occurred and is continuing

  . Equistar or a wholly owned subsidiary is the surviving person

  . in the case of any transaction in which the consideration paid by
    Equistar has an aggregate value in excess of 10% of Equistar's
    consolidated net tangible assets, Equistar submit calculations showing
    pro forma compliance with the two financial ratio covenants discussed
    above

The $1.25 billion revolving credit facility also provides that Equistar may not
sell, lease, transfer or assign or otherwise dispose of either

  . Equistar's assets, substantially as an entirety

  . assets representing more than 10% of consolidated net tangible assets,
    unless Equistar delivers pro forma consolidated financial information
    demonstrating compliance with the two covenants discussed above

   The $1.25 billion revolving credit facility limits Equistar's ability to
engage in business other than the type engaged in as of the date of the
facility and business reasonably related to not more than 10% of consolidated
net tangible assets. The $1.25 billion revolving credit facility also limits
the use of proceeds of borrowings under the facility and restricts Equistar's
ability to enter into or permit to exist any agreement that restricts the
ability of a material subsidiary to pay dividends or other distributions or to
make or repay loans or advances to Equistar.

   Events of default under the $1.25 billion revolving credit facility include

  . breach of representation or warranty

  . default in payment of principal

  . default in payment of interest that continues for a period of five days

  . failure to comply with any one of the negative covenants described above
    for a period of 30 days after we receive notice

  . bankruptcy of Equistar or a material subsidiary

  . default under other indebtedness of Equistar, if the effect of that
    default is to accelerate or to permit the holder to accelerate that
    indebtedness in excess of $50 million

  . nonpayment when due of any amount of principal of or interest on any
    indebtedness of Equistar in an aggregate principal amount in excess of
    $50 million

  . default in payment of principal in excess of $15 million, when due and
    payable or principal in excess of $15 million is declared due and payable
    before the date on which it would otherwise be due and payable

  . failure of Lyondell, Millennium and Occidental at any time to own in the
    aggregate, through ownership by one or more of them, at least a majority
    of the total equity interest and voting power of Equistar

                                      110

   Millennium America Inc., a subsidiary of Millennium, provided limited
guarantees with respect to the payment of principal and interest on a total of
$750 million principal amount of indebtedness under the $1.25 billion revolving
credit facility. However, the lenders may not proceed against Millennium
America Inc. until they have exhausted their remedies against Equistar. The
guarantee will remain in effect indefinitely, but at any time after December 1,
2004, Millennium America Inc. may elect to terminate the guarantee if all of
the following conditions exist:

  . Equistar's ratio of total indebtedness to total capitalization is, as of
    the most recently completed fiscal quarter, lower than the same ratio for
    the 12-month period ending December 31, 1998

  . Equistar's ratio of earnings before interests, taxes, depreciation and
    amortization to net interest for the most recent 12-month period is at
    least 105% of the same ratio for the 12-month period ending December 31,
    1998

  . Equistar is not then in default in the payment of principal of, or
    interest on, any indebtedness for borrowed money in excess of $15 million

  . Equistar is not then in default in respect of any covenants, other than
    those relating to payment of principal and/or interest, relating to any
    indebtedness for borrowed money if the effect of a default shall be to
    accelerate, or to permit the holder or obligee of such indebtedness, or
    any trustee on behalf of a holder or obligee, to accelerate, with or
    without the giving of notice or lapse of time or both, the indebtedness
    in an aggregate amount in excess of $50 million

   In addition, if Millennium GP and Millennium LP sell all of their respective
interests in Equistar to an unaffiliated third party at any time, or if
Millennium Petrochemicals sells all of its interests in both Millennium GP and
Millennium LP, Millennium America Inc. may elect to terminate its guarantee if,
at the time of the sale or termination, Equistar has an investment grade credit
rating or the fair market value of Equistar's assets is at least 140% of the
gross amount of its liabilities.

   On June 12, 1998, Equistar entered into a $500 million credit facility
consisting of a $250 million revolving credit facility and a $250 million one-
year term facility with Bank of America National Trust and Savings Association
and Chase Bank of Texas, National Association, as agents, and BancAmerica
Robertson Stephens and Chase Securities Inc., as arrangers, and the lenders a
party thereto from time to time. This facility was terminated in February 1999.

Assumed Lyondell Debt

   At Equistar's formation, Equistar assumed specific long-term notes and
debentures of Lyondell. At June 1, 1999 following repayment of $150 million of
10% notes due June 1, 1999, the outstanding portion of those obligations
consists of

  . $100 million aggregate principal amount 9.125% notes due 2002

  . $150 million 6.50% notes due 2006

  . $150 million aggregate principal amount debentures due 2026

  . $163 million aggregate principal amount of medium-term notes with various
    maturities ranging from February 2000 to March 2005 and with various
    fixed interest rates ranging from 9.50% to 11.30%

Lyondell continues to be liable to the debtholders on these notes and
debentures as well, although Equistar and Lyondell have agreed that Equistar
will indemnify Lyondell with respect to the assumed debt. As a result, as
between Equistar and Lyondell, Lyondell is effectively secondarily liable.

   All of the assumed Lyondell debt provides that neither Equistar nor any
restricted subsidiary may incur debt secured by a lien on any principal
petrochemical plant or refinery or on the stock of any subsidiary that owns any
principal petrochemical plant or refinery, unless Equistar equally and ratably
secures the assumed

                                      111
<PAGE>

Lyondell debt. This requirement does not apply to some categories of liens,
substantially the same as those permitted under the outstanding notes and the
new notes, such as pre-existing liens, liens to secure all or a part of the
construction, and liens to secure debt incurred to secure payment for property
or to secure debt incurred before, at the time of or within 24 months after
acquisition of the property. Equistar is also allowed to incur secured debt,
which in the aggregate, together with the aggregate value of all sale and
leaseback transactions for which no indebtedness has been retired, does not at
any one time exceed the greater of $50 million or 10% of Equistar's
consolidated net tangible assets. Some of the assumed Lyondell debt also
restricts the incurrence of debt by any subsidiary that owns either of
Equistar's Channelview, Texas olefins plants.

   The assumed Lyondell debt also provides that Equistar may not enter into a
sale and leaseback transaction unless Equistar would be allowed to incur, under
the test described in the foregoing paragraph, secured debt in principal amount
equal to or exceeding the value of the sale and leaseback transaction, without
equally and ratably securing the assumed Lyondell debt. This restriction does
not apply if Equistar voluntarily repays indebtedness in an amount equal to the
value of the sale and leaseback transaction within four months of the sale and
leaseback transaction.

   The events of default under the assumed Lyondell debt include

  . default in the payment of interest upon the applicable series of debt
    securities that continues for 30 days

  . default in the payment of principal of the applicable series of debt
    securities when due and payable

  . failure to observe any other applicable covenant 90 days after written
    notice

  . bankruptcy

   Lyondell's medium-term notes, which have been assumed by Equistar, have a
provision providing for the right of the noteholders to require repurchase of
the medium-term notes upon the occurrence of events involving an obligor (which
includes both Equistar and Lyondell) under the medium-term notes. These rights
are triggered if there is a "designated event" followed by a specified drop in
the rating of the securities. A designated event includes

  . a person acquires more than 20% of the voting stock of the obligor

  . during any period of two consecutive years, individuals who at the
    beginning of that two-year period constituted the obligor's board of
    directors, or new directors whose nomination was approved by at least
    two-thirds of the directors who were directors at the beginning of that
    period or whose nomination was similarly approved, cease to constitute a
    majority

  . an obligor consolidates or merges with or into any other corporation or
    conveys, transfers or leases all or substantially all of its assets to
    any person or any corporation consolidates with or mergers into the
    obligor, in either event under a transaction in which any shares of
    voting stock of the obligor outstanding immediately before the
    transaction are exchanged into or exchanged for cash, securities or other
    property

  . an obligor acquires beneficial ownership in excess of 30% of its own
    voting stock

  . an obligor makes distributions other than regular cash dividends to
    holders of voting stock or purchases voting stock, and the sum of those
    distributions and purchases is 30% or more of the fair market value of
    all outstanding stock

  . during any year, an obligor makes distributions other than regular cash
    dividends or repurchases voting stock other than up to $25 million in
    repurchases that may be made in connection with employee benefit plans,
    and the sum of those distributions and purchases exceeds an amount equal
    to the obligor's net cash flow for the prior fiscal year less the
    aggregate amount of regular quarterly dividends paid during the same
    prior fiscal year

                                      112
<PAGE>

The right to require repurchase is triggered if a designated event is followed
within 90 days of public notice of the designated event by (a) a downgrade to
below investment grade if the medium-term notes are rated investment grade and
(b) a downgrade of at least one full ratings category if the medium-term notes
are rated below investment grade.

                              Plan of Distribution

   Based on interpretations by the staff of the SEC in no action letters issued
to third parties, we believe that you may transfer new notes issued under the
exchange offers in exchange for the outstanding notes if you both

  . acquire the new notes in the ordinary course of your business

  . are not engaged in, and do not intend to engage in, and have no
    arrangement or understanding with any person to participate in, a
    distribution of new notes

Broker-dealers receiving new notes in the exchange offers will be subject to a
prospectus delivery requirement with respect to resales of the new notes. The
letter of transmittal states that by acknowledging and delivering a prospectus,
a broker-dealer will not be deemed to admit that it is an "underwriter" within
the meaning of the Securities Act. This prospectus, as it may be amended or
supplemented from time to time, may be used by a broker-dealer in connection
with resales of new notes received in exchange for outstanding notes where the
outstanding notes were acquired by the broker-dealer as a result of market-
making activities or other trading activities.

   We believe that you may not transfer new notes issued under the exchange
offers in exchange for the outstanding notes if you are either

  . our "affiliate" within the meaning of Rule 405 under the Securities Act

  . a broker-dealer that acquired outstanding notes directly from us

  . a broker-dealer that acquired outstanding notes as a result of market-
    making or other trading activities without compliance with the
    registration and prospectus delivery provisions of the Securities Act

   To date, the staff of the SEC has taken the position that participating
broker-dealers may fulfill their prospectus delivery requirements with respect
to transactions involving an exchange of securities such as this exchange
offers, other than a resale of an unsold allotment from the original sale of
the outstanding notes, with the prospectus contained in the exchange offers
registration statement. Broker-dealers who acquired the outstanding notes from
Equistar may not rely on SEC staff interpretations. They must comply with the
registration and prospectus delivery requirements of the Securities Act--
including being named as selling noteholders--in order to resell the
outstanding notes or the new notes. In the exchange and registration rights
agreement, we have agreed to permit participating broker-dealers use of this
prospectus in connection with the resale of new notes. We have agreed that, for
a period up to 180 days after the expiration of the exchange offers, we will
make this prospectus, and any amendment or supplement to this prospectus,
available to any broker-dealer that requests these documents in the letter of
transmittal. In addition, until December 2, 1999, all dealers effecting
transactions in the new notes may be required to deliver a prospectus.

   If you wish to exchange your outstanding notes for new notes in the exchange
offers, you will be required to make representations to us as described in "The
Exchange Offers--Purpose and Effect of the Exchange Offers" and "The Exchange
Offers--Procedures for Tendering--Your Representations to Us" of this
prospectus and in the letter of transmittal. In addition, if you are a broker-
dealer who receives new notes for your own account in exchange for outstanding
notes that were acquired by you as a result of market-making activities or
other trading activities, you will be required to acknowledge that you will
deliver a prospectus meeting the requirements of the Securities Act in
connection with any resale by you of new notes.

                                      113
<PAGE>

   We will not receive any proceeds from any sale of new notes by broker-
dealers. Broker-dealers who receive new notes for their own account in the
exchange offers may sell them from time to time in one or more transactions
either

  . in the over-the-counter market

  . in negotiated transactions

  . through the writing of options on the new notes or a combination of
    methods of resale

  . at market prices prevailing at the time of resale

  . at prices related to prevailing market prices or negotiated prices

   Any resale may be made directly to purchasers or to or through brokers or
dealers who may receive compensation in the form of commissions or concessions
from any broker-dealer or the purchasers of any new notes. Any broker-dealer
that resells new notes it received for its own account in the exchange offers
and any broker or dealer that participates in a distribution of new notes may
be deemed to be an "underwriter" within the meaning of the Securities Act. Any
profit on any resale of new notes and any commissions or concessions received
by any persons may be deemed to be underwriting compensation under the
Securities Act. The letter of transmittal states that, by acknowledging that it
will deliver and by delivering a prospectus, a broker-dealer will not be deemed
to admit that it is an "underwriter" within the meaning of the Securities Act.

   We have agreed to pay all expenses incidental to the exchange offers other
than commissions and concessions of any brokers or dealers. We will indemnify
holders of the outstanding notes, including any broker-dealers, against some
liabilities, including liabilities under the Securities Act, as provided in the
exchange and registration rights agreement.

                   NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

1. Basis of Preparation

   The accompanying unaudited financial statements have been prepared in
accordance with generally accepted accounting principles for interim financial
information and with the instructions to Form 10-Q and Rule 10-01 of Regulation
S-X. Accordingly, they do not include all of the information and footnotes
required by generally accepted accounting principles for complete financial
statements. In the opinion of management, all adjustments, consisting only of
normal, recurring adjustments considered necessary for a fair presentation,
have been included. Certain amounts from prior periods have been reclassified
to conform to the current period presentation.

   The preparation of these financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

2. Company Operations

   Pursuant to a partnership agreement (the "Partnership Agreement") Lyondell
Petrochemical Company ("Lyondell") and Millennium Chemicals Inc. ("Millennium")
formed Equistar Chemicals, LP, a Delaware limited partnership, which commenced
operations on December 1, 1997. The Partnership is a joint venture and the
businesses contributed by Lyondell and Millennium consisted of non-monetary
assets and were accounted for on a predecessor basis. From December 1, 1997 to
May 15, 1998, the Partnership was owned 57 percent by Lyondell and 43 percent
by Millennium. Lyondell owns its interest in the Partnership through two
wholly-owned subsidiaries, Lyondell Petrochemical G.P. Inc. ("Lyondell GP") and
Lyondell Petrochemical L.P. Inc. ("Lyondell LP"). Millennium also owns its
interest in the Partnership through two wholly-owned subsidiaries, Millennium
Petrochemicals GP LLC ("Millennium GP") and Millennium Petrochemicals LP LLC
("Millennium LP").

   On May 15, 1998, the Partnership was expanded with the contribution of
certain assets from Occidental Petroleum Corporation ("Occidental"). These
assets include the ethylene, propylene and ethylene oxide ("EO") and
derivatives businesses and certain pipeline assets held by Oxy Petrochemicals
Inc. ("Oxy Petrochemicals"), a 50% interest in a joint venture between PDG
Chemical Inc. (" PDG Chemical") and du Pont de Nemours and Company, and a lease
to the Partnership of the Lake Charles, Louisiana olefins plant and related
pipelines held by Occidental Chemical Corporation ("Occidental Chemical")
(collectively, the "Occidental Contributed Business"). Occidental Chemical, Oxy
Petrochemicals and PDG Chemical are all wholly-owned, indirect subsidiaries of
Occidental. The Occidental Contributed Business included olefins plants at
Corpus Christi and Chocolate Bayou, Texas; EO/ethylene glycol ("EG") and EG
derivatives businesses located at Bayport, Texas, Occidental's 50% ownership of
PD Glycol, which operates EO/EG plants at Beaumont, Texas, 950 miles of owned
and leased ethylene/propylene pipelines and the lease to the Partnership of the
Lake Charles, Louisiana olefins plant and related pipelines.

   In exchange for the Occidental Contributed Business, two subsidiaries of
Occidental were admitted as limited partners and a third subsidiary was
admitted as a general partner in the Partnership for an aggregate partnership
interest of 29.5%. In addition, the Partnership assumed approximately $205
million of Occidental indebtedness and the Partnership issued a promissory note
to an Occidental subsidiary in the amount of $419.7 million. In connection with
the contribution of the Occidental Contributed Business and the reduction of
Millennium's and Lyondell's ownership interests in the Partnership, the
Partnership also issued a promissory note to Millennium LP in the amount of $75
million. The consideration paid for the Occidental Contributed Business was
determined based upon arms-length negotiations between Lyondell, Millennium and
Occidental. In connection with the transaction, the Partnership and Occidental
also entered into a long-term agreement for the Partnership to supply the
ethylene requirements for Occidental Chemical's US manufacturing plants.

                             EQUISTAR CHEMICALS, LP

             NOTES TO FINANCIAL STATEMENTS (UNAUDITED)--(Continued)


   Upon completion of this transaction, the Partnership is now owned 41% by
Lyondell through wholly-owned subsidiaries, 29.5% by Millennium through wholly-
owned subsidiaries and 29.5% by Occidental, through its wholly-owned
subsidiaries Occidental Petrochem Partner GP Inc. ("Occidental GP"), Occidental
Petrochem Partner 1, Inc. ("Occidental LP1") and Occidental Petrochem Partner
2, Inc. ("Occidental LP2").

   The Partnership owns and operates the petrochemicals and polymers businesses
contributed by Lyondell, Millennium and Occidental (the "Contributed
Businesses") which consist of 17 manufacturing facilities on the US Gulf Coast
and in the US Midwest. The petrochemicals segment produces products including
ethylene, propylene and butadiene; aromatics, including benzene and toluene;
oxygenated chemicals, including ethylene oxide and derivatives, and methyl
tertiary butyl ether ("MTBE"); ethyl alcohol and diethyl ether; and specialty
chemicals, including refinery building blocks. These products are used
primarily in the production of other chemicals and products, including
polymers. The petrochemicals segment also includes sales of methanol produced
by Lyondell Methanol LP ("Lyondell Methanol"), which is owned 75 percent by
Lyondell. The Partnership operates the Lyondell Methanol facility. The polymers
segment produces polyolefins, including high-density polyethylene ("HDPE"),
low-density polyethylene ("LDPE"), linear low-density polyethylene ("LLDPE"),
and polypropylene; and performance polymers products, including color
concentrates and compounds; wire and cable resins and compounds; adhesive
resins; and fine powders, which are used in the production of a wide variety of
consumer and industrial products. The color concentrates and compounds business
was sold on April 30, 1999 (see note 3).

   The Partnership Agreement provides that Equistar is governed by a
Partnership Governance Committee consisting of nine representatives, three
appointed by each partner. Most of the significant decisions of the Partnership
Governance Committee require unanimous consent, including approval of the
Partnership's Strategic Plan and annual updates thereof.

   Pursuant to the Partnership Agreement, net income is allocated among the
partners on a pro rata basis based on their percentage ownership of the
Partnership. Distributions are made to the partners based on their percentage
ownership of the Partnership. Additional contributions required by the
Partnership will also be based on the partners' percentage ownership of the
Partnership.

3. Sale of Concentrates and Compounds Business

   On April 30, 1999, Equistar completed the sale of its concentrates and
compounds business to Ampacet Corporation. The transaction included two
manufacturing facilities, located in Heath, Ohio and Crockett, Texas, and
related inventories. Equistar recorded a net gain on the sale of approximately
$42 million.

8. Commitments and Contingencies

   The Partnership has various purchase commitments for materials, supplies and
services incident to the ordinary conduct of business. In the aggregate, such
commitments are not at prices in excess of current market.

   The Partnership is also subject to various lawsuits and proceedings. Subject
to the uncertainty inherent in all litigation, management believes the
resolution of these proceedings will not have a material adverse effect upon
the financial statements or liquidity of the Partnership.

   Equistar has agreed to indemnify and defend Lyondell and Millennium,
individually, against certain uninsured claims and liabilities which Equistar
may incur relating to the operation of the Contributed Business prior to
December 1, 1997 up to $7 million each within the first seven years of the
Partnership, subject to certain terms of the Asset Contribution Agreements.
Equistar has also agreed to indemnify Occidental up to $7 million on a similar
basis relating to the operation of the Occidental Contributed Business prior to
May 15, 1998. During the six months ended June 30, 1999 and 1998, the
Partnership incurred $4 million and $2 million, respectively, in expenses for
these uninsured claims and liabilities.

   The Partnership's policy is to be in compliance with all applicable
environmental laws. The Partnership is subject to extensive environmental laws
and regulations concerning emissions to the air, discharges to surface and
subsurface waters and the generation, handling, storage, transportation,
treatment and disposal of waste materials. Some of these laws and regulations
are subject to varying and conflicting interpretations. In addition, the
Partnership cannot accurately predict future developments, such as increasingly
strict requirements of environmental laws, inspection and enforcement policies
and compliance costs therefrom which might affect the handling, manufacture,
use, emission or disposal of products, other materials or hazardous and non-
hazardous waste. The Partnership had no reserves for environmental matters as
of June 30, 1999.

   Certain federal and state governmental initiatives have sought either to
rescind the oxygenate requirement for reformulated gasoline or to restrict the
use of MTBE. These initiatives or other governmental actions could result in a
significant reduction in Equistar's MTBE sales.

   In the opinion of management, any liability arising from the matters
discussed in this Note is not expected to have a material adverse effect on the
financial statements or liquidity of the Partnership. However, the adverse
resolution in any reporting period of one or more of these matters discussed in
this Note could have a material impact on the Partnership's results of
operations for that period without giving effect to contribution or
indemnification obligations of co-defendants or others, or to the effect of any
insurance coverage that may be available to offset the effects of any such
award.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Partnership Governance Committee
of Equistar Chemicals, LP:

   In our opinion, the accompanying balance sheets and the related statements
of income, of partners' capital and of cash flows present fairly, in all
material respects, the financial position of Equistar Chemicals, LP (the
"Partnership") at December 31, 1998 and 1997, and the results of its operations
and its cash flows for the year ended December 31, 1998 and for the period from
December 1, 1997 (inception) to December 31, 1997, in conformity with generally
accepted accounting principles. These financial statements are the
responsibility of the Partnership's management; our responsibility is to
express an opinion on these financial statements based on our audits. We
conducted our audits of these statements in accordance with generally accepted
auditing standards which require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements, assessing
the accounting principles used and significant estimates made by management,
and evaluating the overall financial statement presentation. We believe that
our audits provide a reasonable basis for the opinion expressed above.

                         NOTES TO FINANCIAL STATEMENTS

1. Formation of the Company and Operations

   Pursuant to a partnership agreement (the "Partnership Agreement") Lyondell
Chemical Company ("Lyondell") and Millennium Chemicals, Inc. ("Millennium")
formed Equistar Chemicals, LP ("Equistar" or the "Partnership"), a Delaware
limited partnership, which commenced operations on December 1, 1997. The
Partnership is a joint venture and the businesses contributed by Lyondell and
Millennium consisted of non-monetary assets and were accounted for on a
predecessor basis. From December 1, 1997 to May 15, 1998, the Partnership was
owned 57 percent by Lyondell and 43 percent by Millennium. Lyondell owns its
interest in the Partnership through two wholly-owned subsidiaries, Lyondell
Petrochemical G.P. Inc. ("Lyondell GP") and Lyondell Petrochemical L.P. Inc.
("Lyondell LP"). Millennium also owns its interest in the Partnership through
two wholly-owned subsidiaries, Millennium Petrochemicals GP LLC ("Millennium
GP") and Millennium Petrochemicals LP LLC ("Millennium LP").

   On May 15, 1998, the Partnership was expanded with the contribution of
certain assets from Occidental Petroleum Corporation ("Occidental") (see Note
3). These assets include the ethylene, propylene and ethylene oxide ("EO") and
EO derivatives businesses and certain pipeline assets held by Oxy
Petrochemicals Inc. ("Oxy Petrochemicals"), a 50 percent interest in a joint
venture between PDG Chemical Inc. ("PDG Chemical") and Du Pont de Nemours and
Company ("PD Glycol"), and a lease to the Partnership of the Lake Charles,
Louisiana olefins plant and related pipelines held by Occidental Chemical
Corporation ("Occidental Chemical") (collectively, the "Occidental Contributed
Business"). Occidental Chemical, Oxy Petrochemicals and PDG Chemical are
wholly-owned, indirect subsidiaries of Occidental. The Occidental Contributed
Business included olefins plants at Corpus Christi and Chocolate Bayou, Texas,
EO/ethylene glycol and EO derivatives businesses located at Bayport, Texas,
Occidental's 50 percent ownership of PD Glycol, which operates a polyglycol
plant at Beaumont, Texas, 1,430 miles of owned and leased ethylene/propylene
pipelines, and the lease to the Partnership of the Lake Charles, Louisiana
olefins plant and related pipelines.

   In exchange for the Occidental Contributed Business, two subsidiaries of
Occidental were admitted as limited partners and a third subsidiary was
admitted as a general partner in the Partnership for an aggregate partnership
interest of 29.5 percent. In addition, the Partnership assumed approximately
$205 million of Occidental indebtedness and the Partnership issued a promissory
note to an Occidental subsidiary in the amount of $419.7 million, which was
subsequently paid in cash in June 1998. In connection with the contribution of
the Occidental Contributed Business and the reduction of Millennium's and
Lyondell's ownership interests in the Partnership, the Partnership also issued
a promissory note to Millennium LP in the amount of $75 million, which was
subsequently paid in June 1998. These payments are included in distributions to
partners in the accompanying statements of partners' capital and of cash flows.
The consideration paid for the Occidental Contributed Business was determined
based upon arms-length negotiations between Lyondell, Millennium, and
Occidental. In connection with the transaction, the Partnership and Occidental
also entered into a long-term agreement for the Partnership to supply the
ethylene requirements for Occidental Chemical's U.S. manufacturing plants.

   After completion of this transaction, the Partnership is owned 41 percent by
Lyondell through wholly-owned subsidiaries, 29.5 percent by Millennium through
wholly-owned subsidiaries and 29.5 percent by Occidental, through its wholly-
owned subsidiaries Occidental Petrochem Partner GP Inc. ("Occidental GP"),
Occidental Petrochem Partner 1, Inc. ("Occidental LP1") and Occidental
Petrochem Partner 2, Inc. ("Occidental LP2").

   The Partnership owns and operates the petrochemicals and polymers businesses
contributed by Lyondell, Millennium, and Occidental (the "Contributed
Businesses") which consist of 20 manufacturing facilities on the U.S. Gulf
Coast and in the U.S. Midwest. The petrochemicals segment manufactures and
markets olefins, oxygenated chemicals, aromatics and specialty chemicals.
Olefins include ethylene, propylene and butadiene, and oxygenated chemicals
include ethylene oxide, ethylene glycol, ethanol and methyl tertiary butyl
ether

                   NOTES TO FINANCIAL STATEMENTS--(Continued)

("MTBE"). The petrochemicals segment also includes the production and sale of
aromatics including benzene and toluene. The polymers segment manufactures and
markets polyolefins, including high-density polyethylene ("HDPE"), low-density
polyethylene ("LDPE"), linear low-density polyethylene ("LLDPE"),
polypropylene, and performance polymers, all of which are used in the
production of a wide variety of consumer and industrial products. The
performance polymers include enhanced grades of polyethylene, including wire
and cable resins, concentrates and compounds, and polymeric powders.

   The Partnership Agreement provides that Equistar is governed by a
Partnership Governance Committee consisting of nine representatives, three
appointed by each partner. Most of the significant decisions of the Partnership
Governance Committee require unanimous consent, including approval of the
Partnership's Strategic Plan and annual updates thereof.

   Pursuant to the Partnership Agreement, net income is allocated among the
partners on a pro rata basis based on their percentage ownership of the
Partnership. Distributions are made to the partners based on their percentage
ownership of the Partnership. Additional cash contributions required by the
Partnership will also be based on the partners' percentage ownership of the
Partnership.

2. Summary of Significant Accounting Policies

   Revenue Recognition--Revenue from product sales is recognized upon delivery
of products to the customer.

   Cash and Cash Equivalents--Cash equivalents consist of highly liquid debt
instruments such as certificates of deposit, commercial paper and money market
accounts purchased with an original maturity date of three months or less. Cash
equivalents are stated at cost, which approximates fair value. The
Partnership's policy is to invest cash in conservative, highly rated
instruments and limit the amount of credit exposure to any one institution. The
Partnership performs periodic evaluations of the relative credit standing of
these financial institutions which are considered in the Partnership's
investment strategy.

   The Partnership has no requirements for compensating balances in a specific
amount at a specific point in time. The Partnership does maintain compensating
balances for some of its banking services and products. Such balances are
maintained on an average basis and are solely at the Partnership's discretion.
As a result, none of the Partnership's cash is restricted.

   Accounts Receivable--The Partnership sells its products primarily to
companies in the petrochemicals and polymers industries. The Partnership
performs ongoing credit evaluations of its customers' financial condition and,
in certain circumstances, requires letters of credit from them. The
Partnership's allowance for doubtful accounts, which is reflected in the
accompanying balance sheet as a reduction of accounts receivable, totaled $3
million at December 31, 1998. The Partnership had no allowance for doubtful
accounts recorded at December 31, 1997.

   Inventories--Inventories are stated at the lower of cost or market. Cost is
determined on the last-in, first-out ("LIFO") basis except for materials and
supplies, which are valued at average cost.

   Property, Plant and Equipment--Property, plant and equipment are recorded at
cost. Depreciation of property, plant and equipment is computed using the
straight-line method over the estimated useful lives of the related assets,
ranging from 5 to 30 years.

   Upon retirement or sale, the Partnership removes the cost of the assets and
the related accumulated depreciation from the accounts and reflects any
resulting gains or losses in the statement of income. The Partnership's policy
is to capitalize interest cost incurred on debt during the construction of
major projects exceeding one year.

                   NOTES TO FINANCIAL STATEMENTS--(Continued)


   Turnaround Maintenance and Repair Expenses--Cost of major repairs and
maintenance incurred in connection with substantial overhauls or maintenance
turnarounds of production units at the Partnership's manufacturing facilities
are deferred and amortized on a straight-line basis until the next planned
turnaround, generally five to seven years. These costs are maintenance, repair
and replacement costs that are necessary to maintain, extend and improve the
operating capacity and efficiency rates of the production units. The
Partnership amortized $20 million and $2 million of deferred turnaround
maintenance and repair costs for the year ended December 31, 1998 and during
the period from December 1, 1997 (inception) to December 31, 1997,
respectively.

   Deferred Software Costs--Costs to purchase and develop software for internal
use are deferred and amortized on a straight-line basis over 10 years. The
Partnership amortized $6 million and less than $1 million of deferred software
costs for the year ended December 31, 1998 and during the period from December
1, 1997 (inception) to December 31, 1997, respectively.

   Goodwill--Goodwill includes goodwill contributed by Millennium and goodwill
recorded in connection with the contribution of Occidental's assets. Goodwill
is being amortized using the straight-line method over forty years. Management
periodically evaluates goodwill for impairment based on the anticipated future
cash flows attributable to the related operations. Such expected cash flows, on
an undiscounted basis, are compared to the carrying value of the tangible and
intangible assets, and if impairment is indicated, the carrying value of
goodwill, and if necessary other related assets, is adjusted. Management
believes that no impairment exists at December 31, 1998. The Partnership
amortized $31 million and $3 million of goodwill for the year ended December
31, 1998 and during the period from December 1, 1997 (inception) to December
31, 1997, respectively. Accumulated amortization of goodwill was $166 million
and $135 million at December 31, 1998 and 1997, respectively.

   Investment in PD Glycol--Equistar holds a 50 percent interest in a joint
venture with Du Pont de Nemours and Company that owns an ethylene glycol
facility in Beaumont, Texas. This investment was contributed by Occidental in
1998. The investment in PD Glycol is accounted for under the equity method.

   Environmental Remediation Costs--Expenditures related to investigation and
remediation of contaminated sites, which include operating facilities and waste
disposal sites, are accrued when it is probable a liability has been incurred
and the amount of the liability can reasonably be estimated. Estimates have not
been discounted to present value. Environmental remediation costs are expensed
or capitalized in accordance with generally accepted accounting principles.

   Pension and Other Postretirement Benefit Plans--During 1998, the Partnership
adopted Statement of Financial Accounting Standards ("SFAS") No. 132,
Employers' Disclosures about Pensions and Other Retirement Benefits. The
provisions of SFAS No. 132 revise employers' disclosures about pension and
other postretirement benefit plans. It does not change the measurement or
recognition of these plans. SFAS No. 132 standardizes the disclosure
requirements for these plans, to the extent practicable.

   Exchanges--Finished product exchange transactions, which involve homogeneous
commodities held for sale in the ordinary course in the same line of business
and do not involve the payment or receipt of cash, are not accounted for as
purchases and sales. Any resulting volumetric exchange balances are accounted
for as inventory in accordance with the normal LIFO valuation policy.

   Income Taxes--The Partnership is not subject to federal income taxes as
income is reportable directly by the individual partners; therefore, there is
no provision for income taxes in the accompanying financial statements.

                   NOTES TO FINANCIAL STATEMENTS--(Continued)


   Use of Estimates--The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amount of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

   Segment and Related Information--In 1998, the Partnership adopted SFAS No.
131, Disclosures about Segments of an Enterprise and Related Information. SFAS
No. 131 supercedes SFAS No. 14, Financial Reporting for Segments of a Business
Enterprise, replacing the "industry segment" approach with the "management"
approach. The management approach designates the internal organization that is
used by management for making operating decisions and assessing performance as
the source of the Partnership's reportable segments. SFAS No. 131 also requires
disclosures about products and services, geographic areas and major customers.
The adoption of SFAS No. 131 did not affect the results of operations or the
financial position of the Partnership (see Note 18).

   Comprehensive Income--Effective January 1, 1998, Equistar adopted SFAS No.
130, Reporting Comprehensive Income. Equistar had no items of other
comprehensive income during the year ended December 31, 1998 and the one-month
period ended December 31, 1997.

   Derivatives--In June 1998, the Financial Accounting Standards Board issued
Statement of Financial Accounting Standards ("SFAS") No. 133, Accounting for
Derivative Instruments and Hedging Activities. The statement is effective for
Equistar's calendar year 2001; however, early adoption is permitted. SFAS No.
133 requires that all derivative instruments be recorded on the balance sheet
at their fair value. Changes in fair value of derivatives are recorded each
period in current earnings or other comprehensive income, depending upon
whether a derivative is designated as part of a hedge transaction and, if it
is, the type of hedge transaction. The gains and losses on the derivative
instrument that are reported in other comprehensive income will be reclassified
as earnings in the periods in which earnings are impacted by the hedged item.
The ineffective portion of all hedges will be recognized in current-period
earnings. Equistar does not intend to adopt this pronouncement prior to 2001.

   Reclassifications--Certain 1997 amounts have been restated to conform to
classifications adopted in 1998.

3. Addition of Occidental Contributed Business

   On May 15, 1998, the Partnership was expanded with the contribution of
certain assets from Occidental. The acquisition was accounted for using the
purchase method of accounting and, accordingly, the results of operations for
these assets are included in the accompanying statement of income prospectively
from May 15, 1998. Occidental contributed assets and liabilities to the
Partnership with a fair value of $2.1 billion in exchange for a 29.5% interest
in the Partnership. (The Partnership also issued a promissory note to an
Occidental subsidiary in the amount of $420 million, which was subsequently
paid in cash in June 1998). The fair value was allocated to the assets
contributed and liabilities assumed based on the estimated fair values of such
assets and liabilities at the date of the contribution. The fair value was
determined based on a combination of internal valuations performed by Lyondell,
Millennium and Occidental using the income approach. The fair value of the
assets contributed and liabilities assumed by the Partnership on May 15, 1998
is as follows:

5. Financial Instruments

   The fair value of all financial instruments included in current assets and
current liabilities, including cash and cash equivalents, accounts receivable,
accounts payable, and accrued liabilities approximated their carrying value due
to their short maturity. Based on the borrowing rates currently available to
the Partnership for debt with terms and average maturities similar to the
Partnership's debt portfolio, the fair value of the Partnership's long-term
debt, including amounts due within one year, was approximately $2.3 billion and
$1.5 billion at December 31, 1998 and 1997, respectively.

   The Partnership had issued letters of credit totaling $2.6 million and $4
million at December 31, 1998 and 1997, respectively.

6. Related Party Transactions

   Loans to Millennium and Occidental--In connection with Occidental's entry
into Equistar in May 1998, Equistar executed promissory notes to Millennium and
Occidental in the principal amounts of $75.0 million and $419.7 million,
respectively. Each of the notes provides for the annual accrual of interest
(based on a year of 360 days and actual days elapsed) at a rate equal to LIBOR
plus .6 percent. These notes were paid in full in June 1998. Interest expense
incurred on these notes during 1998 was $3 million.

   Note Receivable from Lyondell LP--Upon formation of the Partnership,
Lyondell LP contributed capital to the Partnership in the form of a $345
million promissory note (the "Lyondell Note"). The Lyondell Note bears interest
at LIBOR plus a market spread. The note was repaid in full by Lyondell in July
1998. Interest income accrued on the Lyondell note totaled $12.8 million and
$1.75 million during 1998 and during the period from December 1, 1997
(inception) to December 31, 1997, respectively.

   Shared Services Agreement with Lyondell--Lyondell provides certain
corporate, general and administrative services to the Partnership, including
legal, tax, treasury, risk management and other services pursuant to a shared
services agreement. During the year ended December 31, 1998, Lyondell charged
the Partnership $3 million for these services. During the period December 1,
1997 (inception) to December 31, 1997, charges from Lyondell were less than $1
million. As part of the shared services agreement, the Partnership provides

                             EQUISTAR CHEMICALS, LP

                   NOTES TO FINANCIAL STATEMENTS--(Continued)

certain general and administrative services to Lyondell, such as health, safety
and environmental services, human resource services, information services and
legal services. During the year ended December 31, 1998 and during the period
December 1, 1997 (inception) to December 31, 1997, the Partnership charged
Lyondell less than $1 million for these services.

   Shared Services and Shared-Site Agreements with Millennium--The Partnership
and Millennium have entered into a variety of operating, manufacturing and
technical service agreements related to the business of Equistar and the vinyl
acetate monomers, acetic acid, synthesis gas and methanol businesses retained
by Millennium Petrochemicals. These agreements include the provision by the
Partnership to Millennium Petrochemicals of materials management, certain
utilities, administrative office space, health, safety and environmental
services and computer services. During the year ended December 31, 1998, the
Partnership charged Millennium Petrochemicals $5 million for these services.
During the period from December 1, 1997 (inception) to December 31, 1997,
charges to Millennium Petrochemicals were less than $1 million. These
agreements also include the provision by Millennium Petrochemicals to the
Partnership of certain operational services, including waste water treatment
and barge dock access. During the year ended December 31, 1998 and during the
period December 1, 1997 (inception) to December 31, 1997, Millennium
Petrochemicals charged the Partnership less than $1 million for these services.

   Operating Agreement with Occidental Chemical Corporation--On May 15, 1998,
Occidental Chemical and the Partnership entered into an Operating Agreement
(the "Operating Agreement") whereby Occidental Chemical agreed to operate and
maintain the Occidental Contributed Business and to cause third-parties to
continue to provide equipment, products and commodities to those businesses
upon substantially the same terms and conditions as provided prior to the
transfer. Under the terms of the Operating Agreement, the Partnership agreed to
reimburse Occidental Chemical for its cost in connection with the services
provided to the Partnership, and the Partnership agreed to pay Occidental
Chemical an administrative fee. The Operating Agreement terminated in
accordance with its terms on June 1, 1998. During the term of the Operating
Agreement, the Partnership paid Occidental Chemical an administrative fee of $1
million.

   Transition Services Agreement with Occidental Chemical--On June 1, 1998,
Occidental Chemical and the Partnership entered into a Transition Services
Agreement (the "TSA"). Under the terms of the TSA, Occidental Chemical agreed
to provide the Partnership certain services in connection with the Occidental
Contributed Business, including services related to accounting, payroll, office
administration, marketing, transportation, purchasing and procurement,
management, human resources, customer service, technical services and others.
Between June 1, 1998 and December 31, 1998, the Partnership expensed $6 million
in connection with services provided pursuant to the TSA. The TSA expires by
its terms on June 1, 1999.

   Occidental Chemical Ethylene Sales Agreement--The Partnership and Occidental
Chemical entered into a Sales Agreement, dated May 15, 1998 (the "Ethylene
Sales Agreement"). Under the terms of the Ethylene Sales Agreement, Occidental
Chemical has agreed to purchase an annual minimum amount of ethylene from the
Partnership equal to 100 percent of the ethylene feedstock requirements of
Occidental Chemical's United States plants (estimated to be 2 billion pounds
per year at the time of the signing of the agreement) less any quantities up to
250 million pounds tolled in accordance with the provisions of such agreement.
The Partnership's maximum supply obligation in any calendar year under the
Ethylene Sales Agreement is 2.55 billion pounds. Upon three years notice from
either party to the other, the Partnership's maximum supply obligation in any
calendar year under the Ethylene Sales Agreement may be "phased down" as set
forth in the agreement, provided that no phase down may occur prior to January
1, 2009. In accordance with the phase down provisions of the agreement, the
annual minimum requirements set forth in the agreement must be phased down over
at least a five year period so that the annual required minimum can not decline
to zero prior to December 31, 2013 unless certain specified force majeure
events occur. The Ethylene Sales Agreement

                             EQUISTAR CHEMICALS, LP

                   NOTES TO FINANCIAL STATEMENTS--(Continued)

provides for an ethylene sales price that is generally reflective of market
prices and will be determined pursuant to a formula using the Partnership's
sales price to third parties and several published market price indices. During
the period from May 15, 1998 to December 31, 1998, the Partnership charged
Occidental Chemical $171 million under the Ethylene Sales Agreement.

   Product Sales to Millennium--The Partnership sells ethylene to Millennium at
market-related prices pursuant to an agreement entered into in connection with
the formation of Equistar. Under this agreement, Millennium is required to
purchase 100 percent of its ethylene requirements for its LaPorte, Texas
facility (estimated to be 300 million pounds per year), up to a maximum of 330
million pounds per year. Millennium has the option to increase the amount
purchased to up to 400 million pounds per year beginning January 1, 2001. The
initial term of the contract expires December 1, 2000 and thereafter, the
contract automatically renews annually. Either party may terminate on one
year's notice, except that if Millennium elects to increase its purchases under
the contract, a party must provide two year's notice of termination. The
pricing terms of this agreement are similar to the Ethylene Sales Agreement
with Occidental Chemical. The Partnership charged Millennium $41 million and $4
million for ethylene for 1998 and December 1997, respectively.

   Product Sales to Lyondell--Lyondell acquired its intermediate chemicals and
derivatives business through the acquisition of ARCO Chemical Company effective
August 1, 1998. Sales to Lyondell, primarily for ethylene, propylene, MTBE,
benzene and alkylate, totaled $97 million for the period from August 1, 1998 to
December 31, 1998, and were based on price terms generally reflective of
market.

   Transactions with LCR.--Lyondell's rights and obligations under the terms of
its product sales and feedstock purchase agreements with LYONDELL-CITGO
Refining LP ("LCR"), a joint venture investment of Lyondell, were assigned to
the Partnership. Accordingly, certain refinery products are sold to the
Partnership as feedstocks, and certain olefins by-products are sold to LCR for
processing into gasoline. Sales to LCR were $236 million and $27 million and
purchases from LCR were $131 million and $10 million for the year ended
December 31, 1998 and for the period from December 1, 1997 (inception) to
December 31, 1997, respectively. The Partnership also assumed certain tolling
arrangements as well as terminalling and storage obligations between Lyondell
and LCR and performs certain marketing services for LCR. Aggregate charges
under these various service agreements of $15 million were made to LCR by the
Partnership with respect to 1998. No charges were made during December 1997.
All of the agreements between LCR and the Partnership are on terms generally
representative of prevailing market prices. The Partnership also has a shared
services agreement with LCR to provide LCR with information services, including
mainframe processing and maintenance. Net charges to LCR by the Partnership for
the shared services agreement were less than $1 million during 1998. No charges
were made during December 1997.

   Transactions with Lyondell Methanol--The Partnership provides operating and
other services for Lyondell Methanol Company, L.P. ("Lyondell Methanol") under
the terms of existing agreements that were assumed by Equistar from Lyondell,
including the lease to Lyondell Methanol by the Partnership of the real
property on which its methanol plant is located. Pursuant to the terms of those
agreements, Lyondell Methanol pays the Partnership a management fee and will
reimburse certain expenses of the Partnership at cost. Management fees charged
by the Partnership to Lyondell Methanol totaled $6 million for the year ending
December 31, 1998 and less than $1 million during the period from December 1,
1997 (inception) to December 31, 1997. The Partnership sells natural gas to
Lyondell Methanol at prices generally representative of its cost. Purchases by
Lyondell Methanol of natural gas feedstock from the Partnership totaled $44
million and $4 million for the year ended December 31, 1998 and during the
period from December 1, 1997 (inception) to December 31, 1997, respectively.
Lyondell Methanol sells all of its products to Equistar. For the year ending
December 31, 1998 and during the period from December 1, 1997 (inception) to

Partnership, Millennium subleases from the Partnership certain administrative
office space at a monthly rent of $42,000.

7. Accounts Receivable

   In December 1998, the Partnership entered into a purchase agreement with an
independent issuer of receivables-backed commercial paper. Under the terms of
the agreement, the Partnership agreed to sell on an ongoing basis and without
recourse, designated accounts receivable. To maintain the balance of the
accounts receivable sold, the Partnership is obligated to sell new receivables
as existing receivables are collected. The agreement expires in December 1999.

   At December 31, 1998, the Partnership's gross accounts receivable that had
been sold to the purchasers aggregated $130 million. This amount has been
reported as operating cash flows in the statement of cash flows. Costs related
to the sale are included in selling, general and administrative expenses in the
statement of income.

                   NOTES TO FINANCIAL STATEMENTS--(Continued)


   In July 1998, the depreciable lives of certain assets, primarily
manufacturing facilities and equipment, were increased from a range of 5 to 25
years to a range of 5 to 30 years. The change was made to more accurately
reflect the estimated periods during which such assets will remain in service,
based on the Partnership's actual experiences with those assets. This change
was accounted for as a change in accounting estimate and resulted in a $33
million decrease in depreciation expense for 1998.

                   NOTES TO FINANCIAL STATEMENTS--(Continued)

   Aggregate maturities of long-term debt during the five years subsequent to
December 31, 1998 are as follows: 1999-$302 million; 2000-$247 million; 2001-
$90 million; 2002-$1.251 billion; 2003-$29 million. All of the above debt is
guaranteed by the partners as of December 31, 1998.

   The medium-term notes mature at various dates from 2000 to 2005 and have a
weighted average interest rate of 9.87 percent and 9.83 percent at December 31,
1998 and 1997, respectively.

   The Partnership has a five-year, $1.25 billion credit facility (the
"Facility") with a group of banks expiring November 2002. Borrowings under the
Facility bear interest at either the Federal Funds rate plus 1/2 of 1 percent,
LIBOR plus 1/2 of 1 percent, a fixed rate offered by one of the sponsoring
banks or interest rates that are based on a competitive auction feature wherein
the interest rate can be established by competitive bids submitted by the
sponsoring banks, depending on the type of borrowing made under the Facility.
Borrowings under the Facility had a weighted average interest rate of 5.8
percent and 5.7 percent at December 31, 1998 and 1997, respectively. Millennium
America Inc., a subsidiary of Millennium, provided limited guarantees with
respect to the payment of principal and interest on a total of $750 million
principal amount of indebtedness under the $1.25 billion revolving credit
facility. However, the lenders may not proceed against Millennium America Inc.
until they have exhausted their remedies against Equistar. The guarantee will
remain in effect indefinitely, but at any time after December 1, 2004,
Millennium America Inc. may elect to terminate the guarantee if certain
conditions are met including financial ratios and covenants. Occidental
Chemical Corporation, a wholly owned subsidiary of Occidental, provided a
similar limited guarantee to Equistar on a total of $419.7 million principal
amount of indebtedness under the credit facility, which has since been
terminated.

   On June 12, 1998, the Partnership entered into a $500 million credit
agreement consisting of a $250 million revolving credit facility and a $250
million one-year term facility. Borrowings under the $500 million credit
agreement bear interest at either the Federal Funds rate plus 1/2 of 1 percent,
LIBOR plus 0.625 percent, a fixed rate offered by one of the sponsoring banks
or interest rates that are based on a competitive auction feature wherein the
interest rate can be established by competitive bids submitted by the
sponsoring banks. At December 31, 1998, the weighted average interest rate for
borrowings under the $500 million credit agreement was 6.1 percent.

   The Facility and the $500 million credit agreement (the "Bank Credit
Facilities") are available for working capital and general purposes as needed
and contain covenants relating to liens, sale and leaseback transactions, debt
incurrence, leverage and interest coverage ratios, sales of assets and mergers
and consolidations.

   In February 1999, the Partnership and Equistar Funding Corporation
("Equistar Funding") co-issued $900 million of debt securities. (Equistar
Funding, a wholly owned subsidiary of Equistar, is a Delaware corporation
formed for the sole purpose of facilitating the financing activities of
Equistar). Equistar is jointly and severally liable with Equistar Funding on
the outstanding notes and the new notes. The debt securities include $300
million of 8.50 percent Notes, which will mature on February 15, 2004, and $600
million of 8.75 percent Notes, which will mature on February 15, 2009. The
Partnership intends to use the net proceeds from this offering (i) to repay the
$205 million outstanding under a capitalized lease obligation relating to the
Partnership's Corpus Christi facility, (ii) to repay the outstanding balance
under the $500 million credit agreement, after which the $500 million credit
agreement will be terminated, (iii) to repay the outstanding $150 million, 10.0
percent Notes due in June 1999, upon maturity and (iv) to the extent of the
remaining net proceeds, reduce outstanding borrowings under the Facility and
for Partnership working capital. Outstanding borrowings under the Partnership's
$500 million credit agreement that are payable in 1999 are included as long-
term obligations of the Partnership in the accompanying balance sheet at
December 31, 1998 based on the expectation that these borrowings will be
refinanced as described above.

13. Restructuring and Other Unusual Charges

   The Partnership incurred restructuring charges related to the initial merger
and integration of the businesses contributed by Lyondell and Millennium upon
formation of the Partnership. The Partnership recorded $42 million of these
costs in December 1997. These charges included severance and other employee
related termination costs related to a workforce reduction ($21 million), which
were included in other accrued liabilities at December 31, 1997 and were
substantially paid in 1998. The workforce reduction included approximately 430
employees, primarily in duplicate corporate overhead functions. All of these
430 employees were terminated in 1998. Additionally, these restructuring
charges included employee relocation costs ($6 million) and various other
charges ($7 million), all of which were recorded and paid as incurred in 1997.
In 1997, the Partnership also recorded and paid as incurred transaction closing
costs of $8 million. In 1998, the Partnership recorded and paid, as incurred,
an additional $12 million in restructuring charges related to the initial
merger and integration of the Partnership. These costs included costs
associated with the consolidation of operations and facilities ($11 million)
and other miscellaneous charges ($1 million). The restructuring actions related
to the initial merger and integration were substantially completed in 1998 and
there were no significant changes to the Partnership's original estimate of
costs that were accrued as of December 31, 1997. There were no amounts accrued
as of December 31, 1998 related to the initial merger and integration of the
Partnership. All restructuring charges were included in the Unallocated
segment.

   The Partnership also incurred restructuring charges of $2 million related to
the merger and integration of the Occidental contributed business into the
Partnership. These charges were recorded and paid as incurred during 1998.
There were no amounts accrued as of December 31, 1998 related to the merger and
integration of the Occidental contributed business. All restructuring charges
were included in the Unallocated segment. The restructuring actions related to
the merger and integration of the Occidental contributed business into the
Partnership were substantially completed as of December 31, 1998.

15. Retirement Plans

   All full-time regular employees of the Partnership are covered by defined
benefit pension plans sponsored by the Partnership. The plans became effective
on January 1, 1998, except for union represented employees formerly employed by
Millennium, whose plans were contributed to the Partnership on December 1,
1997, and union represented employees formerly employed by Occidental, whose
plans were contributed to the Partnership on May 15, 1998. In connection with
the formation of the Partnership, there were no pension assets or obligations
contributed to the Partnership, except for the union represented plans
described above. Retirement benefits are based on years of service and the
employee's highest three consecutive years of compensation during the last ten
years of service. The funding policy for these plans is to make periodic
contributions as required by applicable law. The Partnership accrues pension
costs based on an actuarial valuation and funds the plans through contributions
to pension trust funds. The Partnership also has unfunded supplemental
nonqualified retirement plans which provide pension benefits for certain
employees in excess of the tax qualified plans' limits.

   As of December 31, 1998, Equistar had defined benefit pension plans where
the accumulated benefit obligation exceeded the fair value of plan assets. The
accumulated benefit obligation exceeded the fair value of plan assets by $19
million for these plans as of December 31, 1998. As of December 31, 1998 and
1997, Equistar had defined benefit pension plans where the fair value of plan
assets exceeded the accumulated benefit obligation. The fair value of plan
assets exceeded the accumulated benefit obligation by $19 million for these
plans as of December 31, 1998 and 1997.

   The Partnership's net periodic pension cost for 1998 included the following

                   NOTES TO FINANCIAL STATEMENTS--(Continued)


   As the non-union plans became effective on January 1, 1998, the Partnership
did not recognize any net periodic pension cost during the period from December
1, 1997 (inception) to December 31, 1997.

   Effective January 1, 1998, the Partnership also maintains voluntary defined
contribution savings plans for eligible employees. Under provisions of the
plans, the Partnership contributes an amount equal to 160 percent of employee
contributions up to a maximum matching contribution of eight percent of the
employee's base salary. Contributions to the plans by the Partnership were $7
million and less than $1 million for the year ended December 31, 1998 and
during the period from December 1, 1997 (inception) to December 31, 1997,
respectively.

16. Postretirement Benefits Other Than Pensions

   The Partnership sponsors unfunded postretirement benefit plans other than
pensions ("OPEB") for both salaried and non-salaried employees, which provide
medical and life insurance benefits. The postretirement health care plans are
contributory while the life insurance plans are non-contributory. Currently,
the Partnership pays approximately 80 percent of the cost of the health care
plans, but reserves the right to modify the cost-sharing provisions at any
time. In connection with the formation of the Partnership on December 1, 1997,
Lyondell and Millennium contributed $31 million of accrued postretirement
benefit liabilities for employees that transferred to the Partnership. Upon
joining the Partnership in May 1998, Occidental contributed $14 million of
accrued postretirement benefit liabilities for employees that transferred to
the Partnership

   The following table provides a reconciliation of benefit obligations and
funded status of the OPEB plans at December 31, 1998 and 1997:

   Because the OPEB plans are unfunded, there was no change in the plan assets
during the year ended December 31, 1998 and for the period from December 1,
1997 (inception) to December 31, 1997.

   The Partnership's postretirement benefit costs for 1998 included the
following components:

                                                                            ===
        Net periodic benefit cost.........................................  $ 7
                                                                            ===
</TABLE>

   The accrued postretirement benefit liabilities at December 31, 1997 were
calculated and contributed as of December 31, 1997; therefore, there was no net
periodic postretirement benefit costs for the period from December 1, 1997
(inception) to December 31, 1997.

   For measurement purposes, the assumed annual rate of increase in the per
capita cost of covered health care benefits as of December 31, 1998 was 7.0
percent for 1999-2001 and 5.0 percent thereafter. The health care cost trend
rate assumption does not have a significant effect on the amounts reported. To
illustrate, increasing the assumed health care cost trend rates by one
percentage point in each year would increase the accumulated postretirement
benefit liability as of December 31, 1998 by less than $1 million and would not
have a material effect on the aggregate service and interest cost components of
the net periodic postretirement benefit cost for the year then ended.
Decreasing the assumed health care cost trend rates by one percentage point in
each year would decrease the accumulated postretirement benefit liability as of
December 31, 1998 by $1 million and would not have a material effect on the
aggregate service and interest cost components of the net periodic
postretirement benefit cost for the year then ended.

17. Commitments and Contingencies

   The Partnership has various purchase commitments for materials, supplies and
services incident to the ordinary conduct of business. In the aggregate, such
commitments are not at prices in excess of current market.

   The Partnership is also subject to various lawsuits and proceedings. Subject
to the uncertainty inherent in all litigation, management believes the
resolution of these proceedings will not have a material adverse effect upon
the financial statements or liquidity of the Partnership.

   Equistar has agreed to indemnify and defend Lyondell and Millennium,
individually, against certain uninsured claims and liabilities which Equistar
may incur relating to the operation of the Contributed Business prior to
December 1, 1997 up to $7 million each within the first seven years of the
Partnership, subject to certain terms of the Asset Contribution Agreements.
Equistar has also agreed to indemnify Occidental up to $7 million on a similar
basis relating to the operation of the Occidental Contributed Business prior to
May 15, 1998. During the year ended December 31, 1998, the Partnership incurred
$5 million in expenses for these uninsured claims and liabilities. No expenses
were incurred for these uninsured claims and liabilities during the period
December 1, 1997 (inception) to December 31, 1997.

   The Partnership's policy is to be in compliance with all applicable
environmental laws. The Partnership is subject to extensive environmental laws
and regulations concerning emissions to the air, discharges to surface and
subsurface waters and the generation, handling, storage, transportation,
treatment and disposal of waste materials. Some of these laws and regulations
are subject to varying and conflicting interpretations. In addition, the
Partnership cannot accurately predict future developments, such as increasingly
strict requirements of environmental laws, inspection and enforcement policies
and compliance costs therefrom which might affect the handling, manufacture,
use, emission or disposal of products, other materials or hazardous and non-
hazardous waste. The Partnership had no reserves for environmental matters as
of December 31, 1998 and 1997.

                   NOTES TO FINANCIAL STATEMENTS--(Continued)


   In the opinion of management, any liability arising from the matters
discussed in this Note is not expected to have a material adverse effect on the
financial statements or liquidity of the Partnership. However, the adverse
resolution in any reporting period of one or more of these matters discussed in
this Note could have a material impact on the Partnership's results of
operations for that period without giving effect to contribution or
indemnification obligations of co-defendants or others, or to the effect of any
insurance coverage that may be available to offset the effects of any such
award.

18. Segment Information

   Using the guidelines set forth in SFAS No. 131, Disclosures about Segments
of an Enterprise and Related Information, the Partnership has identified two
segments in which it operates. The reportable segments are petrochemicals and
polymers. The petrochemicals segment includes olefins, oxygenated chemicals,
aromatics and specialty chemicals. Olefins include ethylene, propylene and
butadiene, and the oxygenated chemicals include ethylene oxide, ethylene
glycol, ethanol and MTBE. The petrochemicals segment also includes the
production and sale of aromatics including benzene and toluene. The polymers
segment consists of polyolefins including high-density polyethylene, low-
density polyethylene, linear low-density polyethylene, polypropylene, and
performance polymers. The performance polymers include enhanced grades of
polyethylene, including wire and cable resins, concentrates and compounds, and
polymeric powders.

   No customer accounted for 10 percent or more of sales.

   The accounting policies of the segments are the same as those described in
"Summary of Significant Accounting Policies" (see Note 2).

   Summarized financial information concerning the Partnership's reportable
segments is shown in the following table. Intersegment sales between the
petrochemicals and polymers segments were made at prices based on current
market values.

19. Subsequent Events

   In January 1999, the Partnership announced that it was going to shut down
and "mothball" its gas phase HDPE reactor at Port Arthur, Texas, on March 31,
1999, as part of its long-term strategy to maximize value. The shutdown will
reduce the Partnership's HDPE capacity by 300 million pounds per year and
reduce employment at the unit from 200 to approximately 125. Customers for
products from the mothballed unit will be supplied with comparable products
produced at the Partnership's Matagorda, Victoria, and LaPorte, Texas,
facilities. This transaction is not expected to have a material impact on
Equistar's financial condition, results of operations or liquidity.

                         REPORT OF INDEPENDENT ACCOUNTANTS

To the Stockholders and Board of Directors
of Lyondell Petrochemical Company:

   In our opinion, the accompanying balance sheets and the related statements
of income and invested capital and of cash flows present fairly, in all
material respects, the financial position of the contributed petrochemicals and
polymers businesses of Lyondell Petrochemical Company ("Lyondell Contributed
Business") at November 30, 1997 and December 31, 1996, and the results of
operations, and cash flows for the eleven month period ended November 30, 1997
and each of the two years in the period ended December 31, 1996 in conformity
with generally accepted accounting principles. These financial statements are
the responsibility of the Lyondell Contributed Business's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits in accordance with generally accepted
auditing standards which require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, and evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for the
opinion expressed above.

                         NOTES TO FINANCIAL STATEMENTS
                                 (In millions)

Note 1. Basis of Presentation and Description of the Contributed Business

   As of December 1, 1997, Lyondell Petrochemical Company ("Lyondell" or the
"Company") and Millennium Chemicals Inc. ("Millennium") formed a new joint
venture company named Equistar Chemicals, LP (the "Partnership") which is
being operated as a partnership. The Partnership, which is owned 57% by the
Company and 43% by Millennium, owns and operates the existing olefins and
polymers businesses contributed by the two companies. The assets of the
Partnership consist of 15 manufacturing facilities on the US Gulf Coast and in
the US Midwest, producing ethylene, propylene, polyethylene (high-density,
low-density and linear low-density), polypropylene, ethyl alcohol, butadiene,
aromatics, methyl butyl tertiary ether ("MTBE") and other products for sale to
customers throughout the US. The Partnership has $1,745 of debt including $745
face value of debt assumed from Lyondell and $750 under a new credit facility,
the proceeds of which will be used to repay debt assumed from Millennium upon
completion of the transaction, and a note receivable from Lyondell of $345.

   On March 20, 1998, Lyondell and Millennium announced an agreement to expand
the Partnership with the addition of the ethylene, propylene, and ethylene
oxide and derivative businesses of Occidental Chemical Corporation
("OxyChem"), a subsidiary of Occidental Petroleum. Following the closing of
the agreement on May 15, 1998, Lyondell's percentage ownership in the
Partnership decreased to 41 percent from 57 percent, with Millennium and
OxyChem each owning a 29.5 percent share.

   Lyondell contributed to the Partnership substantially all of the net assets
and operations comprising its petrochemicals and polymers segments. Lyondell
retained ownership of its 58.75% interest in LYONDELL-CITGO Refining Company
Ltd. ("LYONDELL-CITGO Refining") and its 75% interest in Lyondell Methanol
Company, L.P. ("Lyondell Methanol").

   The accompanying financial statements include the results of operations,
assets and liabilities of the petrochemicals and polymers businesses currently
owned by Lyondell that will be contributed to the Partnership ("Contributed
Business"). These financial statements are presented on a going concern basis
and include only the historical net assets and results of operations that are
directly related to the Contributed Business. Consequently, the financial
position, results of operations and cash flows may not be indicative of what
would have been reported if the Contributed Business had been a separate,
stand-alone entity or had been operated as a part of the Partnership.

   Lyondell provided certain corporate, general and administrative services to
the Contributed Business, including legal, tax, treasury, risk management and
other services. The Contributed Business provided certain general and
administrative services to Lyondell, including computer, office lease and
employee benefits services. Charges for the services are believed to be
reasonable and substantially offset each other for the periods presented. In
addition, Lyondell has controlled, on a centralized basis, all cash receipts
and disbursements received or made by the Contributed Business. The net
results of such transactions are included in the balance sheets as invested
capital.

Note 2. Significant Accounting Policies

   Revenue Recognition. Revenue from product sales is recognized upon delivery
of product to the customer.

   Use of Estimates. The preparation of financial statements in conformity
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported amounts of assets

and liabilities at the date of the financial statements and the reported amount
of revenues and expenses during the reporting period. Actual results could
differ from those estimates.

   Cash and Cash Equivalents. Cash equivalents consist of highly liquid debt
instruments such as certificates of deposit, commercial paper and money market
accounts purchased with an original maturity date of three months or less.

   Accounts Receivable. The Contributed Business sells its products primarily
to companies in the petrochemicals and polymers industries. The Contributed
Business performs ongoing credit evaluations of its customers' financial
condition and in certain circumstances requires letters of credit from them.
The Contributed Business's allowance for doubtful accounts, which is reflected
in the balance sheet as a reduction of accounts receivable, totaled $3 at
November 30, 1997 and December 31, 1996.

   Inventories. Inventories are stated at the lower of cost or market value.
Cost is determined on the last-in, first-out ("LIFO") basis, except for
materials and supplies, which are valued at average cost. Inventories valued on
a LIFO basis were approximately $44 and $46 less than the amount of such
inventories valued at current cost at November 30, 1997 and December 31, 1996,
respectively.

   Inventories consist of the following:

   Property, Plant and Equipment. Property, plant and equipment are recorded at
cost. Depreciation of property, plant and equipment is computed using the
straight-line method over the estimated useful lives of the assets, generally 5
to 30 years for manufacturing facilities and equipment. Interest cost incurred
on debt during the construction of major projects that exceed one year is
capitalized. No interest was capitalized during the periods presented.
Property, plant and equipment consists of the following:

</TABLE>

   Accounts payable and certain accrued expenses were not contributed to the
Partnership at its formation.

   Environmental Remediation Costs. Expenditures related to investigation and
remediation of contaminated sites, which include operating facilities and
waste disposal sites, are accrued when it is probable a liability has been
incurred and the amount of the liability can reasonably be estimated. Accrued
liabilities are exclusive of claims against third parties (except where
payment has been received or the amount of liability or contribution by such
other parties, including insurance companies, has been agreed) and are not
discounted. In general, costs related to environmental remediation are charged
to expense. Environmental costs are capitalized if the costs increase the
value of the property and/or mitigate or prevent contamination from future
operations.

   Exchanges. Finished product exchange transactions, which are of a
homogeneous nature of commodities in the same line of business and do not
involve the payment or receipt of cash, are not accounted for as purchases and
sales. Any resulting volumetric exchange balances are accounted for as
inventory in accordance with the normal LIFO valuation policy. Exchanges
settled through payment and receipt of cash are accounted for as purchases and
sales.

   Income Taxes. Earnings of the Contributed Business have been included in
the consolidated federal income tax return filed by Lyondell. Pursuant to an
informal tax allocation agreement, income taxes have been allocated to the
Contributed Business based on applicable statutory tax rates applied to the
taxable earnings generated by such business. The effective income tax rates
were 36.6%, 35.7%, and 36.8% for the eleven months ended November 30, 1997 and
the years ended December 31, 1996, and 1995, respectively. State income tax
was the primary difference between the effective income tax rates and the 35%
federal statutory rate. Liabilities for currently and/or deferred income taxes
have been and remain the responsibility of Lyondell, and accordingly, have
been included in the balance sheet as invested capital.

   As part of the transactions to consummate the Partnership, Lyondell entered
into tax sharing and indemnification agreements with the Partnership in which
Lyondell generally agreed to indemnify the Partnership for income tax
liabilities attributable to periods when the operations of the Contributed
Business were included in the consolidated tax return of Lyondell.

   Research and Development. The cost of research and development efforts is
expensed as incurred. Such costs aggregated $12, $13, and $5 for the eleven
months ended November 30, 1997 and the years ended December 31, 1996, and
1995, respectively.

Note 3. Acquisition of Alathon(R) High-Density Polyethylene Business

   In May 1995, the Company acquired Occidental Chemical Corporation's
Alathon(R) high-density polyethylene ("HDPE") business ("ALATHON Business")
for $356 including certain direct costs, plus

approximately $64 for inventory. Assets involved in the purchased included
resin production facilities at Victoria and Matagorda, Texas, associated
research and development activities and the rights to the Alathon(R) trademark.
These facilities have a combined annual production capacity of approximately
1.5 billion pounds of HDPE. The Company financed the acquisition from internal
cash and $230 of short-term borrowings from its existing financing
arrangements.

   The following unaudited pro forma information combines the results of
operations of the Contributed Business and the ALATHON Business for the year
ended December 31, 1995 and assumes the acquisition of the ALATHON Business
occurred on January 1, 1995. This unaudited pro forma information may not be
indicative of results that would have actually resulted if this transaction had
occurred on January 1, 1995 or which may be obtained in the future.

Note 4. Financial Instruments

   The fair value of all financial instruments included in current assets and
current liabilities, including cash and cash equivalents, accounts receivable,
accounts payable and notes payable, approximated their carrying value due to
their short maturity. Based on the borrowing rates currently available to the
Contributed Business for debt with terms and average maturities similar to the
Contributed Business's debt portfolio, the fair value of the Contributed
Business's long-term debt, including amounts due within one year, was $701 and
$661 at November 30, 1997 and December 31, 1996, respectively.

   The Contributed Business is party to various unconditional purchase
obligation contracts as a purchaser for product and services. At November 30,
1997, future minimum payments under these contracts with noncancelable contract
terms in excess of one year were as follows.

   The Company purchased 383,312 shares of common stock held by ARCO after the
conversion of the Exchangeable Notes on September 15, 1997 at a price of $25.66
per share, eliminating ARCO's ownership interest in the Contributed Business.
Therefore, as of September 30, 1997 ARCO is no longer considered a related
party of the Contributed Business.

   Sales to ARCO Chemical Company, an ARCO affiliate, consisting primarily of
product sales, were $206, $278, and $306 for the nine months ended September
30, 1997 and the years ended December 31, 1996 and 1995, respectively.

   In July of 1996 a fire occurred at the ARCO PipeLine Company meter station
located within the Channelview, Texas petrochemicals facility ("Channelview
Facility"). The fire forced the shutdown of the entire Channelview Facility for
several days and more than two weeks for some units. The Contributed Business
recovered lost profits from ARCO PipeLine Company for this shutdown. The
recovery was included in 1996 reported results.

</TABLE>

   Aggregate maturities of long-term debt during the five years subsequent to
November 30, 1997 are as follows: 1998-$32; 1999-$150, 2000-$42; 2001-$90;
2002-$101. After contribution to the Partnership, Lyondell will continue to be
liable on the above debt until its maturity.

   The Notes due in 1999 and the medium-term notes contain provisions that
would allow the holders to require the Company to repurchase the debt upon the
occurrence of certain events together with specified declines in public ratings
on the Notes due in 1999. Certain events include acquisitions by persons other
than ARCO or the Company of more than 20% of the Company's common stock, any
merger or transfer of substantially all of the Company's assets, in connection
with which the Company's common stock is changed into or exchanged for cash,
securities or other property and payment of certain "special" dividends.

   The medium-term notes mature at various dates from 1998 to 2005 and have a
weighted average interest rate at November 30, 1997, December 31, 1996 and 1995
of 9.8%, 9.8% and 9.9%, respectively.

   Interest paid was $59, $61, and $75 for the eleven months ended November 30,
1997 and the years ended December 31, 1996, and 1995, respectively.

7. Pension and Other Postretirement Benefits

   Defined Benefit Pension Plans--All full-time regular employees of the
Contributed Business are covered by defined benefit pension plans sponsored by
Lyondell. Retirement benefits are based on years of service and the employee's
highest three consecutive years of compensation during the last ten years of
service. The funding policy for these plans is to make periodic contributions
as required by applicable law. The Contributed Business accrues pension costs
based on an actuarial valuation and funds the plans through contributions to
the Company, reflected in invested capital, who then contributes to pension
trust funds separate from Lyondell funds. The Contributed Business also has
unfunded supplemental nonqualified retirement plans which provide pension
benefits for certain employees in excess of the tax qualified plans' limits.
The Contributed Business recorded expense related to participation in these
plans of $7, $7 and $4 for the eleven months ended November 30, 1997 and the
years ended December 31, 1996, and 1995, respectively.

   Defined Contribution Plans--Effective July 1, 1995, Lyondell also maintains
voluntary defined contribution savings plans for eligible employees, including
those employed by the Contributed Business.

Under provisions of the plans, Lyondell contributes an amount equal to 160% of
employee contributions up to a maximum matching contribution of eight percent
of the employee's base salary. Prior to July 1, 1995, Lyondell had similar
voluntary defined contribution plans. The Contributed Business recorded expense
related to participation in these voluntary defined contribution savings plans
totaled $6, $6, and $5 for the eleven months ended November 30, 1997 and the
years ended December 31, 1996, and 1995, respectively.

   Other Postretirement Benefit Plans--Lyondell sponsors unfunded
postretirement benefit plans other than pensions ("OPEB") for both salaried and
non-salaried employees, including those employed by the Contributed Business,
which provide medical and life insurance benefits. The postretirement health
care plans are contributory while the life insurance plans are non-
contributory. Currently, Lyondell pays approximately 80% of the cost of the
health care plans, but reserves the right to modify the cost-sharing provisions
at any time. The Contributed Business recorded expense related to participation
in these plans of approximately $4, $4, and $2 for the eleven months ended
November 30, 1997 and the years ended December 31, 1996, and 1995,
respectively. The actuarially determined liability associated with the
currently active employees of the Contributed Business based on current plan
provisions at November 30, 1997 and December 31, 1996 was $25 and $22,
respectively.

   Operating lease net rental expenses were $42, $44, and $39 for the eleven
months ended November 30, 1997 and the years ended December 31, 1996, and 1995,
respectively.

Note 9. Commitments and Contingencies

   The Contributed Business has various purchase commitments for materials,
supplies and services incident to the ordinary conduct of business. In the
aggregate, such commitments are not at prices in excess of current market.

   In connection with the transfer of assets and liabilities from ARCO to the
Company, the Company and ARCO entered into an agreement ("Cross-Indemnity
Agreement") whereby the Company agreed to defend and indemnify ARCO against
certain uninsured claims and liabilities which ARCO may incur relating to the
operation of the Company's integrated petrochemicals and petroleum processing
business prior to July 1, 1988, including certain liabilities which may arise
out of pending and future lawsuits. ARCO indemnified the Company under the
Cross-Indemnity Agreement with respect to other claims or liabilities and other
matters of litigation not related to the assets or business included in the
Company's consolidated financial statements. The Company has reached an
agreement-in-principle with ARCO to update the Cross-Indemnity Agreement
("Revised Cross-Indemnity Agreement"). The Cross-Indemnity Agreement and the
Revised Cross-Indemnity

                                 (In millions)

Agreement cover operations of the Company included in the Contributed Business.
Subject to the uncertainty inherent in all litigation, management believes the
resolution of the matters pursuant to the Revised Cross-Indemnity Agreement
will not have a material adverse effect upon the financial statements or
liquidity of the Contributed Business.

   In addition to lawsuits for which the Company has indemnified ARCO, the
Company is also subject to various lawsuits and proceedings which may involve
the operations of the Contributed Business. Subject to the uncertainty inherent
in all litigation, management believes the resolution of these proceedings will
not have a material adverse effect upon the consolidated financial statements
or liquidity of the Contributed Business.

   As part of the transactions to consummate the Partnership, Lyondell will
agree to indemnify the Partnership for any present or future liabilities
arising within a seven year period after the consummation of the partnership
which are attributable to the Contributed Business operations prior to the
Partnership's formation in excess of $7.

   The Contributed Business's policy is to be in compliance with all applicable
environmental laws. The Contributed Business is subject to extensive
environmental laws and regulations concerning emissions to the air, discharges
to surface and subsurface waters and the generation, handling, storage,
transportation, treatment and disposal of waste materials. Some of these laws
and regulations are subject to varying and conflicting interpretations. In
addition, the Contributed Business cannot accurately predict future
developments, such as increasingly strict requirements of environmental laws,
inspection and enforcement policies and compliance costs therefrom which might
affect the handling, manufacture, use, emission or disposal of products, other
materials or hazardous and non-hazardous waste.

   As of November 30, 1997 and December 31, 1996, the Contributed Business has
accrued $2 and $3, respectively, related to future regulatory agency assessment
and remediation costs, of which $1 is included in current liabilities at
November 30, 1997 while the remaining amounts are expected to be incurred over
the next two to seven years. In the opinion of management, there is currently
no material range of loss in excess of the amount recorded. However, it is
possible that new information about the sites for which the reserve has been
established, new technology or future developments such as involvement in other
regulatory agency or other comparable state law investigations, could require
the Contributed Business to reassess its potential exposure related to
environmental matters.

   In the opinion of management, any liability arising from the matters
discussed in this Note will not have a material adverse effect on the
consolidated financial statements or liquidity of the Contributed Business.
However, the adverse resolution in any reporting period of one or more of these
matters discussed in this Note could have a material impact on the Contributed
Business's results of operations for that period without giving effect to
contribution or indemnification obligations of co-defendants or others, or to
the effect of any insurance coverage that may be available to offset the
effects of any such award.

material respects, the financial position of the contributed business of
Millennium Chemicals Inc. ("Millennium Contributed Business") at November 30,
1997 and December 31, 1996, and the results of operations, and cash flows for
the eleven month period ended November 30, 1997 and each of the two years in
the period ended December 31, 1996 in conformity with generally accepted
accounting principles. These financial statements are the responsibility of the
Millennium Contributed Business's management; our responsibility is to express
an opinion on these financial statements based on our audits. We conducted our
audits in accordance with generally accepted auditing standards which require
that we plan and perform the audit to obtain reasonable assurance about whether
the financial statements are free of material misstatement. An audit includes

                             (amounts in millions)

NOTE 1--DESCRIPTION OF THE CONTRIBUTED BUSINESS AND OPERATIONS

   Pursuant to a partnership agreement (the "Partnership Agreement"),
Millennium Chemicals Inc. ("Millennium") and Lyondell Petrochemical Company
("Lyondell") formed Equistar Chemicals, LP ("Equistar" or the "Partnership"), a
Delaware limited partnership, which commenced operations on December 1, 1997.
Equistar is 57% owned by Lyondell and 43% owned by Millennium. The Lyondell
interest is owned through two wholly owned subsidiaries, Lyondell Petrochemical
G.P. Inc. ("Lyondell GP") and Lyondell Petrochemical L.P. Inc. ("Lyondell LP").
Millennium also owns its interest in the Partnership through two wholly owned
subsidiaries, Millennium Petrochemicals GP LLC ("Millennium GP") and Millennium
Petrochemicals LP LLC ("Millennium LP").

   The Partnership owns and operates the petrochemical and polymer businesses
contributed by Millennium and Lyondell (the "Contributed Business"). The assets
of the Partnership consist of 15 manufacturing facilities on the U.S. Gulf
Coast and in the U.S. Midwest. The petrochemical segment produces products
including ethylene, propylene, ethyl alcohol, butadiene, aromatics and methyl
tertiary butyl ether ("MTBE"). The products are used primarily in the
production of other chemicals and products, including polymers, for sales to
customers throughout the U.S. The petrochemicals segment also includes sales of
methanol produced by Lyondell Methanol LP ("Lyondell Methanol"), which is owned
75% by Lyondell and is operated by the Partnership. The polymers segment
produces products that include polyethylene (high-density, low-density and
linear low-density), and polypropylene, which are used in the production of a
wide variety of consumer and industrial products.

   In May 1998, Equistar announced that Occidental Petroleum Corporation joined
the Partnership with a contribution of assets and liabilities (the "Occidental
Contributed Business"). The ownership percentages of Equistar after the
inclusion of the Occidental Contributed Business are Lyondell (41%), Millennium
(29.5%) and Occidental (29.5%).

   Millennium contributed to the Partnership substantially all of the net
assets and operations comprising its petrochemicals and polymers segments.
Millennium retained $250 of the accounts receivable of the Contributed
Business.

   The accompanying financial statements include the results of operations,
assets and liabilities of the petrochemicals and polymers businesses owned by
Millennium that were contributed to the Partnership ("Contributed Business").
The financial statements are presented on a going concern basis and include
only the historical net assets and results of operations that are directly
related to the Contributed Business. Consequently, the financial position,
results of operations and the cash flows may not be indicative of what may have
been reported had the Contributed Business been a separate, stand-alone entity
or operated as a part of the Partnership.

   Use of Estimates. The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets, liabilities,
revenues and expenses during the reporting periods. Actual results could differ
from those estimates.

   Trade Receivables. Trade receivables consist of the following:

   Inventories. Inventories are stated at the lower of cost or market value.
Cost is determined for the various categories of inventory using first-in,
first-out ("FIFO"); last-in, first-out ("LIFO") basis or average cost method as
deemed appropriate. Inventories valued on a LIFO basis were approximately $2
and $13 less than the amount of such inventories valued at current cost at
November 30, 1997 and December 31, 1996, respectively.

   Property, Plant and Equipment. Property, plant and equipment is stated on
the basis of cost. Depreciation is computed using the straight-line method over
the estimated useful lives of the assets, generally 20 to 40 years for
buildings and 10 to 25 years for machinery and equipment.

   Property, plant and equipment consists of the following:

   Turnaround Maintenance. Costs relating to future major maintenance projects
are estimated and expensed ratably from the date a turnaround is completed
until the next planned turnaround, generally 4 to 6 years.

   Goodwill. The net assets of the Contributed Business include goodwill of
$1,142 at November 30, 1997, which is being amortized using the straight line
method over forty years. Such goodwill arose from Millennium's 1993 acquisition
of Quantum Chemical Corporation of which the Contributed Business was a

                  NOTES TO FINANCIAL STATEMENTS--(Continued)

part. The value of the purchase consideration was allocated to the acquired
assets and liabilities based on their fair values, resulting in $1,272 of
goodwill being allocated to the Contributed Business. Management periodically
evaluates goodwill for impairment based on the anticipated future cash flows
attributable to the operation. Such expected cash flows, on an undiscounted
basis, are compared to the carrying value of the tangible and intangible
assets, and if impairment is indicated, the carrying value of goodwill is
adjusted. Management believes that no impairment exists at November 30, 1997.
Accumulated amortization aggregated $130 and $101 at November 30, 1997 and
December 31, 1996, respectively. Amortization of goodwill amounted to $29 for
the eleven months ended November 30, 1997 and $31 each for the years ended
December 31, 1996 and 1995, respectively.

   Accrued Expenses and Other Liabilities. Accrued expenses and other
liabilities consist of the following:

</TABLE>

   Accounts payable, feedstock accruals and certain other accrued expenses are
not being contributed to the Partnership at its formation.

   Environmental Remediation Cost. Environmental remediation costs are
expensed or capitalized in accordance with generally accepted accounting
principles. In October 1996, the American Institute of Certified Public
Accountants issued Statement of Position ("SOP 96-1"), "Environmental
Remediation Liabilities," which establishes new accounting and reporting
standards for the recognition and disclosure of environmental remediation
liabilities. The adoption of SOP 96-1 in 1997 did not have a material impact
on the results of operations.

   Research and Development. The cost of research and development efforts is
expensed as incurred. Such costs aggregated $28 for the eleven month period
ended November 30, 1997 and $33 and $32 for the years ended December 31, 1996
and 1995, respectively.

   Exchanges. Finished product exchange transactions, which involve
homogeneous commodities held for sale in the ordinary course in the same line
of business and do not involve the payment or receipt of cash, are not
accounted for as purchases or sales. Any resulting volumetric exchange
balances are accounted for as inventory in accordance with the normal LIFO
valuation policy.

   Federal Income Taxes. Earnings of the Contributed Business have been
included in a consolidated income tax return filed by its ultimate U.S.
parent, Millennium America Holdings Inc. ("MAHI"), a subsidiary of Millennium.
Pursuant to an informal tax allocation agreement, income taxes have been
allocated to the Contributed Business based on applicable statutory tax rates
applied to the taxable earnings generated by such business. Effective income
tax rates for the periods as of and at November 30, 1997 and December 31, 1996
and 1995 were 39.5%, 45.2% and 41.4%, respectively. Differences between the
effective income tax rates and the statutory federal income tax rates arise
primarily from goodwill amortization and state income taxes. Liabilities for
current and/or deferred income taxes have been and remain the responsibility
of MAHI, and accordingly, have been included in the balance sheet as invested
capital.

                             (amounts in millions)


   As part of the transactions to consummate the Partnership, Millennium
entered into tax sharing and indemnification agreements with the Partnership in
which Millennium generally agreed to indemnify the partnership for income tax
liabilities attributable to periods when the operations of the Contributed
Business were included in the consolidated tax return of Millennium. The
Partnership is not subject to federal income taxes as income is reportable
directly by the individual partners; therefore, going forward there will be no
provision for income taxes in the partnership's financial statements.

   Fair Value of Financial Instruments. The fair values of all short-term
financial instruments are estimated to approximate their carrying value because
of their short maturity.

   Earnings Per Share. Historical earnings per share are not presented because
there is no separate identifiable pool of capital for the periods prior to
incorporation upon which a per share calculation could be based.

   Reclassifications. Certain previously reported amounts have been restated to
conform to classifications currently adopted.

NOTE 3--LONG-TERM DEBT AND INDEBTEDNESS TO MILLENNIUM

   The debt included in the balance sheets reflects the obligations directly
related to the Contributed Business including allocated debt from Millennium.

   Interest paid for the eleven months ended November 30, 1997 and the years
ended December 31, 1996 and 1995 was $66, $80 and $80, respectively.

NOTE 4--PENSION AND OTHER POSTRETIREMENT BENEFITS

   All full-time employees of the Contributed Business are covered by defined
benefit pension plans sponsored by Millennium. Retirement benefits are based on
years of service and average compensation as defined under the respective
plans' provisions. The funding policy is to contribute amounts to the plans
sufficient to meet the minimum funding requirements set forth in the Employee
Retirement Income Security Act of 1974. The Contributed Business accrues
pension costs based on actuarial valuations and funds the plan through
contributions to Millennium who then contributes the funds to a master trust
sponsored by Millennium. Such contributions are reflected in invested capital.
Pension income related to participation in these plans was $2, $5 and $4 for
the eleven months ended November 30, 1997 and the years ended December 31, 1996
and 1995, respectively. One such plan covers benefits for union-represented
employees of the Contributed Business. Such plan will be assumed by the
Partnership upon its consummation.

   Millennium also provides unfunded health care and life insurance benefits to
certain groups of retirees. Expenses related to the employees of the
Contributed Business were $3, $2 and $2 for the eleven months ended November
30, 1997 and the years ended December 31, 1996 and 1995, respectively.

NOTE 5--RELATED PARTY TRANSACTIONS

   Millennium provided certain corporate, general and administrative services
to the Contributed Business, including legal, financial, tax, risk management
and employee benefits services. Charges for these services are included in
selling and administration expenses and are believed to be reasonable. In
addition, a subsidiary of Millennium has controlled, on a centralized basis,
all cash receipts and disbursements received or made by the Contributed
Business. The net results of such transactions are included in the balance
sheets as invested capital. The Contributed Business also sells ethylene to an
affiliated business unit of Millennium for the manufacture of vinyl acetate
monomer. Vinyl acetate monomer is sold by Millennium to the Partnership. These
sales are reflected at market price and have been included in the accompanying
income statement. All significant intercompany accounts and transactions within
the Contributed Business have been eliminated. Millennium provides the
Partnership with certain operational services, including waste water treatment
and barge dock access. The Partnership provides certain general and
administrative services to Millennium, including materials management, certain
utilities, office space, health, safety and environmental services and computer
services. The Partnership has also controlled certain cash receipts and
disbursements received or made on behalf of Millennium.

NOTE 6--LEASES

   Rental expense for operating leases was $38, $45 and $43 for the eleven
months ended November 30, 1997 and the years ended December 31, 1996 and 1995,
respectively.

Minimum Rentals

   Future minimum rental commitments under noncancellable operating leases with
terms in excess of one year as of November 30, 1997 are as follows:

NOTE 7--COMMITMENTS AND CONTINGENCIES

   The Contributed Business is subject, among other things, to several
proceedings under the Federal Comprehensive Environmental Response Compensation
and Liability Act and other federal and state statutes. These proceedings are
in various stages ranging from initial investigation to active settlement
negotiations to implementation of clean-up remediation of sites. Additionally,
Millennium and/or its subsidiaries are defendants or plaintiffs in lawsuits
that have arisen in the normal course of business including those relating to
commercial transactions and product liability with respect to the Contributed
Business. The Contributed Business had no reserves for environmental matters at
November 30, 1997.

   As part of the transactions to consummate the Partnership, Millennium agreed
to indemnify the partnership for any present or future liabilities arising
within a seven-year period after the consummation of the Partnership which are
attributable to the Contributed Business's operations prior to the
Partnership's formation in excess of $7.

   The Contributed Business has various contractual obligations to purchase raw
materials used in its production of polyethylene. Commitments to purchase
ethylene used in the production of polyethylene are based on market prices and
expire from 1997 to 2001.

                        OCCIDENTAL CONTRIBUTED BUSINESS

                         NOTES TO FINANCIAL STATEMENTS

                            March 31, 1998 and 1997

                                  (Unaudited)

(1) BASIS OF PRESENTATION AND DESCRIPTION OF THE CONTRIBUTED BUSINESS--

   On May 15, 1998, Occidental Petroleum Corporation (Occidental) signed an
agreement with Lyondell Petrochemical Company and Millenium Chemicals Inc. to
effect the proposed contribution of its ethylene, propylene, ethylene oxide and
ethylene glycol derivatives businesses (collectively, the Occidental
Contributed Business) to a joint venture limited partnership called Equistar
Chemicals, LP (Equistar) in return for a 29.5% interest in Equistar, the
receipt of approximately $420 million in cash and the assumption by Equistar of
approximately $205 million of Occidental capital lease liabilities.

   Under terms of the agreement, on May 15, 1998, Occidental contributed to
Equistar substantially all of the net assets and operations of the Occidental
Contributed Business. The accompanying financial statements include the results
of operations, assets and liabilities of the Occidental Contributed Business
represented by Oxy Petrochemicals Inc., PDG Chemical Inc. and a plant owned by
Occidental Chemical Corporation, which are all indirect subsidiaries of
Occidental Chemical Holding Corporation (OCHC). OCHC is an indirect subsidiary
of Occidental. These financial statements include only the historical results
of operations and net assets that are directly related to the Occidental
Contributed Business. Consequently, the financial position, results of
operations, and cash flows may not be indicative of what would have been
reported if the Occidental Contributed Business had been a separate, stand-
alone entity or had been operated as a part of Equistar during the period
presented. Additionally, certain assets and liabilities of the Occidental
Contributed Business were retained by Occidental. The retained assets will be
leased to Equistar under terms of the agreement.

   Certain information and disclosures normally included in the notes to
financial statements have been condensed or omitted pursuant to Securities and
Exchange Commission (SEC) rules and regulations, but resultant disclosures are
in accordance with generally accepted accounting principles as they apply to
interim reporting. These interim financial statements should be read in
conjunction with the Occidental Contributed Business audited financial
statements as of December 31, 1997 (1997 Financial Statements).

   The accompanying financial statements as of March 31, 1998 and 1997 are
unaudited. All references made to amounts for the period then ended have been
prepared in accordance with the rules and regulations of the SEC. They include
all adjustments which are considered necessary for a fair statement of the
results of operations and financial position of the Occidental Contributed
Business for the interim period presented. Such adjustments consisted only of
normal recurring items.

   Occidental provided certain corporate, general and administrative services
to the Occidental Contributed Business, including legal, financial, marketing
and executive services. Charges for these services were allocated based on the
estimated costs of specific functions performed by Occidental and affiliates
for the Occidental Contributed Business. Management believes the charges, which
amounted to $2.6 million for the three months ended March 31, 1998 and 1997,
are reasonable. Such amounts are included in selling, general and
administrative expenses.

   The Occidental Contributed Business sells ethylene to affiliated businesses
of Occidental. These sales, reflected at market prices and included in the
accompanying Statement of Operations, were $49 million for the three months
ended March 31, 1998 and $73 million for the three months ended March 31, 1997.

   Occidental utilizes a centralized cash management system for its operations,
including the Occidental Contributed Business. Cash distributed to or advanced
from Occidental has been reflected in invested capital in the accompanying
balance sheets. In addition, settlement of transactions with other Occidental
affiliates are recorded through invested capital.

                   NOTES TO FINANCIAL STATEMENTS--(Continued)

(2) SIGNIFICANT ACCOUNTING POLICIES--

 Risks and uncertainties--

   The process of preparing financial statements in conformity with generally
accepted accounting principles requires the use of estimates and assumptions
regarding certain types of assets, liabilities, revenues and expenses. Such
estimates primarily relate to unsettled transactions and events as of the date
of the financial statements. Accordingly, upon settlement, actual results may
differ from estimated amounts, generally not by material amounts. Management
believes that these estimates and assumptions provide a reasonable basis for
the fair presentation of the Occidental Contributed Business' financial
position and results of operations.

   Since the Occidental Contributed Business' major products are commodities,
significant changes in the prices of chemical products could have a significant
impact on the Occidental Contributed Business' results of operations for any
particular period.

 Environmental liabilities and costs--

   Environmental expenditures that relate to current operations are expensed or
capitalized as appropriate. Reserves for estimated costs that relate to
existing conditions caused by past operations and that do not contribute to
current or future revenue generation are recorded when environmental remedial
efforts are probable and the costs can be reasonably estimated. In determining
the reserves, Occidental uses the most current information available, including
similar past experiences, available technology, regulations in effect, the
timing of remediation and cost-sharing arrangements. The environmental reserves
are based on management's estimate of the most likely cost to be incurred and
are reviewed periodically and adjusted as additional or new information becomes
available. The environmental reserves are included in other noncurrent
liabilities and amounted to $7.8 million and $8.2 million at March 31, 1998 and
1997, respectively.

 Income taxes--

   The Occidental Contributed Business has been included in the consolidated
U.S. federal income tax return and in certain unitary state income tax returns
of Occidental. A portion of the income tax provision for these returns is
allocated to the Occidental Contributed Business using the same method as a tax
sharing arrangement between OCHC and Occidental. The Occidental Contributed
Business also records state income tax provisions for operations required to be
reported in separate tax returns. The difference between the provision for
income taxes at the U.S. federal statutory rate and the effective tax rate is
primarily due to state income taxes. Liabilities for current and/or deferred
income taxes have been and remain the responsibility of Occidental and,
accordingly, have been included in the Balance Sheet as invested capital.

 Fair value of financial instruments--

   The fair value of on-balance sheet financial instruments approximates
carrying value. However, the fair value of notes payable to affiliates cannot
be practicably determined due to the related party nature of the balances.

 Change in accounting principle--

   Effective January 1, 1998, the Occidental Contributed Business adopted the
provisions of Statement of Financial Accounting Standards (SFAS) No. 130,
"Reporting Comprehensive Income." This statement establishes standards for
reporting and display of comprehensive income and its components in a full set
of

                                  (Unaudited)

general purpose financial statements. The implementation of SFAS No. 130 did
not have an impact on the Occidental Contributed Business' results of
operations. The Occidental Contributed Business' comprehensive income was $2.3
million for the three months ended March 31, 1998 and comprehensive loss was
$9.3 million for the three months ended March 31, 1997.

(3) RECEIVABLES--

   As of March 31, 1998 and 1997, the Occidental Contributed Business
transferred, with limited recourse, to an Occidental affiliate net domestic
trade receivables under a revolving sale program in connection with the
ultimate sale for cash of an undivided ownership interest in such receivables
by the affiliate. The net trade receivables transferred amounted to $113.7
million and $165.7 million as of March 31, 1998 and 1997, respectively. The
Occidental Contributed Business transferred the receivables to the affiliate in
a noncash transaction that was reflected as a reduction in invested capital.
Occidental retained collection responsibility with respect to the receivables
sold. An interest in newly created receivables is transferred monthly, net of
collections made from customers. Fees related to the sales of receivables under
this program, which are allocated from Occidental, were $1.6 million and $1.7
million for the three months ended March 31, 1998 and 1997, respectively and
are included in other income, net.

   Under the terms of the Equistar agreement, Occidental repurchased the net
domestic trade receivables of $114.8 million of the Occidental Contributed
Business as of May 15, 1998 and contributed $100.3 million to Equistar.

   Other receivables include $3.2 million and $5.1 million as of March 31, 1998
and 1997, respectively, from the equity investee.

(4) INVENTORIES--

   Inventories are stated at the lower of cost or market value determined using
the first-in, first-out (FIFO) or weighted-average-cost methods. Inventories
consist of the following as of March 31 (in thousands):

(5) EQUITY INVESTMENT--

   The Occidental Contributed Business has a fifty percent interest in PD
Glycol, a partnership which manufactures ethylene oxide and ethylene glycol
derivatives at its plant in Beaumont, Texas. The investment, which is accounted
for on the equity method, exceeded the historical underlying equity in net
assets by approximately $43 million at March 31, 1998 and $44 million at March
31, 1997. The excess is being amortized into income over the estimated total
productive life of the plant.

(6) PROPERTY, PLANT AND EQUIPMENT--

   Property additions and major renewals and improvements are capitalized at
cost. Property acquired under a capital lease has been capitalized at the
present value of future minimum lease payments. Depreciation is primarily
provided using the units-of-production method based on estimated total
productive life.

   Interest costs incurred in connection with major capital expenditures are
capitalized and amortized over the lives of the related assets. Capitalized
interest is calculated based on the average borrowing rate of Occidental. The
amount of interest capitalized was $39,000 and $142,000 for the three months
ended March 31, 1998 and 1997, respectively.

   Property, plant and equipment consists of the following as of March 31 (in
thousands):

   Catalyst is amortized over estimated lives ranging from 18 months to 3
years. Deferred start-up costs are amortized over a period of 20 years. Other
amortizable assets are written off to income over the estimated periods to be
benefited.

   In April 1998, the American Institute of Certified Public Accountants issued
Statement of Position 98-5, "Reporting on the Costs of Start-Up Activities"
(SOP 98-5), which requires that costs of start-up activities, including
organizational costs, be expensed as incurred. The initial application of the
statement will result in a charge to income for any costs of start-up
activities that have not yet been fully amortized. Occidental will implement
SOP 98-5 effective January 1, 1999.

   Accrued liabilities consist of the following as of March 31 (in thousands):

</TABLE>

   Maintenance turnarounds are generally performed every 2 to 5 years.
Occidental utilizes an accrual methodology under which it estimates the
projected cost of a turnaround and accrues the cost equally over the years
between turnarounds. Total accruals relating to these future major maintenance
projects were $42.3 million and $21.6 million as of March 31, 1998 and 1997,
respectively, and were included in accrued liabilities as noted above and
deferred credits and other liabilities in the accompanying Balance Sheets.

(9) NOTES PAYABLE TO AFFILIATES--

   The financial statements of the Occidental Contributed Business include
several notes payable to Occidental and an affiliate. Accrued interest on these
notes is settled annually through and is included in invested capital at rates
ranging between 6 and 11 percent. Interest expense on notes payable to
affiliates was $22.8 million for the three months ended March 31, 1998 and
$23.4 million for the three months ended March 31, 1997.

   Principal amounts of the notes payable to an affiliate totaling $63.9
million are due on December 31, 1998. As the amounts will be settled either
through invested capital or another note payable to the affiliate, no notes
payable to affiliates have been classified as current in the accompanying
Balance Sheets.

(10) RETIREMENT PLANS AND POSTRETIREMENT BENEFITS--

   Reference is made to Note 10 of the 1997 Financial Statements regarding
retirement plans and postretirement benefits.

(11) LEASE COMMITMENTS--

   At March 31, 1998, future net minimum lease payments for capital and
operating leases are as follows (in thousands):

   Rental expense for operating leases, excluding leases with terms of one year
or less, was approximately $4 million for each of the three months ended March
31, 1998 and 1997.

                                  (Unaudited)

(12) COMMITMENTS AND CONTINGENCIES--

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

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

   Under the terms of the agreement with Equistar, Occidental has agreed to
indemnify Equistar for any present or future contingent liabilities arising
within a seven year period after May 15, 1998 which are attributable to the
Occidental Contributed Business's operations prior to May 15, 1998 in excess of
$7 million.

   The Occidental Contributed Business has certain other commitments to
purchase electrical power, raw materials and other potential obligations, all
in the ordinary course of business.

(13) SUBSEQUENT EVENT--

   On January 11, 1999, CITGO Petroleum Corporation (CITGO) initiated a legal
action against Occidental Chemical Corporation (OCC) in the United States
District Court for the Northern District of Oklahoma seeking compensatory and
exemplary damages in an unspecified amount. It alleges that OCC breached the
provisions of a Plant Site Right of First Refusal Agreement pertaining to the
Lake Charles plant (Right of First Refusal) dated August 31, 1983, between
CITGO and Cities Service Oil and Gas Corporation, predecessor in interest to
OCC. It is impossible at this time to determine the ultimate legal liabilities,
if any, that may arise from this lawsuit. The CITGO complaint was not filed
against Equistar and seeks only money damages from OCC. However, in
management's opinion, the lawsuit is not likely to have a material adverse
effect upon the financial position of the Occidental Contributed Business.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Board of Directors,
Occidental Chemical Holding Corporation:

We have audited the accompanying balance sheets of the Occidental Contributed
Business as of December 31, 1997 and 1996, and the related statements of
operations and invested capital, and cash flows for each of the three years in
the period ended December 31, 1997. The Occidental Contributed Business is the
ethylene, propylene, ethylene oxide and ethylene glycol derivatives businesses
of Occidental Chemical Holding Corporation included in its indirect
subsidiaries Oxy Petrochemicals Inc., PDG Chemical Inc. and a plant owned by
Occidental Chemical Corporation. These financial statements are the
responsibility of Occidental Chemical Holding Corporation's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of the Occidental Contributed
Business as of December 31, 1997 and 1996, and the results of its operations
and its cash flows for each of the three years in the period ended December 31,
1997, in conformity with generally accepted accounting principles.

Arthur Andersen LLP
Dallas, Texas,

 matter discussed in Note 13, as to which
 the date is January 26, 1999)

                        OCCIDENTAL CONTRIBUTED BUSINESS

                         NOTES TO FINANCIAL STATEMENTS

                        December 31, 1997, 1996 and 1995

(1) BASIS OF PRESENTATION AND DESCRIPTION OF THE CONTRIBUTED BUSINESS--

   On May 15, 1998, Occidental Petroleum Corporation (Occidental) signed an
agreement with Lyondell Petrochemical Company and Millennium Chemicals Inc. to
effect the proposed contribution of its ethylene, propylene, ethylene oxide and
ethylene glycol derivatives businesses (collectively, the Occidental
Contributed Business) to a joint venture limited partnership called Equistar
Chemicals, LP (Equistar) in return for a 29.5% interest in Equistar, receipt of
approximately $420 million in cash and the assumption by Equistar of
approximately $205 million of Occidental capital lease liabilities.

   Under terms of the agreement, on May 15, 1998, Occidental contributed to
Equistar substantially all of the net assets and operations of the Occidental
Contributed Business. The accompanying financial statements include the results
of operations, assets and liabilities of the Occidental Contributed Business
represented by Oxy Petrochemicals Inc., PDG Chemical Inc. and a plant owned by
Occidental Chemical Corporation, which are all indirect subsidiaries of
Occidental Chemical Holding Corporation (OCHC). OCHC is an indirect subsidiary
of Occidental. These financial statements include only the historical results
of operations and net assets that are directly related to the Occidental
Contributed Business. Consequently, the financial position, results of
operations, and cash flows may not be indicative of what would have been
reported if the Occidental Contributed Business had been a separate, stand-
alone entity or had been operated as a part of Equistar during the periods
presented. Additionally, certain assets and liabilities of the Occidental
Contributed Business were retained by Occidental. The retained assets will be
leased to Equistar under terms of the agreement.

   Occidental provided certain corporate, general and administrative services
to the Occidental Contributed Business, including legal, financial, marketing
and executive services. Charges for these services were allocated based on the
estimated costs of specific functions performed by Occidental and affiliates
for the Occidental Contributed Business. Management believes the charges, which
amounted to $10.4 million in each of the years 1997, 1996 and 1995, are
reasonable. Such amounts are included in selling, general and administrative
expenses.

   The Occidental Contributed Business sells ethylene to affiliated businesses
of Occidental. These sales, reflected at market prices and included in the
accompanying Statements of Operations, were $242 million, $227 million and $474
million for the years ended December 31, 1997, 1996 and 1995, respectively.

   Occidental utilizes a centralized cash management system for its operations,
including the Occidental Contributed Business. Cash distributed to or advanced
from Occidental has been reflected in invested capital in the accompanying
balance sheets. In addition, settlement of transactions with other Occidental
affiliates are recorded through invested capital.

(2) SIGNIFICANT ACCOUNTING POLICIES--

 Risks and uncertainties--

   The process of preparing financial statements in conformity with generally
accepted accounting principles requires the use of estimates and assumptions
regarding certain types of assets, liabilities, revenues and expenses. Such
estimates primarily relate to unsettled transactions and events as of the date
of the financial

                                      F-70

                        OCCIDENTAL CONTRIBUTED BUSINESS

                   NOTES TO FINANCIAL STATEMENTS--(Continued)

                        December 31, 1997, 1996 and 1995

statements. Accordingly, upon settlement, actual results may differ from
estimated amounts, generally not by material amounts. Management believes that
these estimates and assumptions provide a reasonable basis for the fair
presentation of the Occidental Contributed Business' financial position and
results of operations.

   Since the Occidental Contributed Business' major products are commodities,
significant changes in the prices of chemical products could have a significant
impact on the Occidental Contributed Business' results of operations for any
particular period.

 Environmental liabilities and costs--

   Environmental expenditures that relate to current operations are expensed or
capitalized as appropriate. Reserves for estimated costs that relate to
existing conditions caused by past operations and that do not contribute to
current or future revenue generation are recorded when environmental remedial
efforts are probable and the costs can be reasonably estimated. In determining
the reserves, Occidental uses the most current information available, including
similar past experiences, available technology, regulations in effect, the
timing of remediation and cost-sharing arrangements. The environmental reserves
are based on management's estimate of the most likely cost to be incurred and
are reviewed periodically and adjusted as additional or new information becomes
available. The environmental reserves are included in other noncurrent
liabilities and amounted to $7.9 million and $8.2 million at December 31, 1997
and 1996, respectively.

 Income taxes--

   The Occidental Contributed Business has been included in the consolidated
U.S. federal income tax return and in certain unitary state income tax returns
of Occidental. A portion of the income tax provision for these returns is
allocated to the Occidental Contributed Business using the same method as a tax
sharing arrangement between OCHC and Occidental. The Occidental Contributed
Business also records state income tax provisions for operations required to be
reported in separate tax returns. The difference between the provision for
income taxes at the U.S. federal statutory rate and the effective tax rate is
primarily due to state income taxes. Liabilities for current and/or deferred
income taxes have been and remain the responsibility of Occidental and,
accordingly, have been included in the Balance Sheets as invested capital.

 Fair value of financial instruments--

   The fair value of on-balance sheet financial instruments approximates
carrying value. However, the fair value of notes payable to affiliates cannot
be practicably determined due to the related party nature of the balances.

 Change in accounting principle--

   Effective January 1, 1998, the Occidental Contributed Business adopted the
provisions of Statement of Financial Accounting Standards (SFAS) No. 130,
"Reporting Comprehensive Income." This statement establishes standards for
reporting and display of comprehensive income and its components in a full set
of general purpose financial statements. The implementation of SFAS No. 130 did
not have an impact on the Occidental Contributed Business' results of
operations. The Occidental Contributed Business' comprehensive income was $85.4
million for 1997, $5.9 million for 1996 and $185.7 million for 1995.

(3) RECEIVABLES--

   As of December 31, 1997, 1996, and 1995, the Occidental Contributed Business
transferred, with limited recourse, to an Occidental affiliate net domestic
trade receivables under a revolving sale program in connection with the
ultimate sale for cash of an undivided ownership interest in such receivables
by the affiliate. The net trade receivables transferred amounted to $136.4
million and $164.3 million as of December 31, 1997 and 1996, respectively. The
Occidental Contributed Business transferred the receivables to the affiliate to
a noncash transaction that was reflected as a reduction in invested capital.
Occidental retained collection responsibility with respect to the receivables
sold. An interest in newly created receivables is transferred monthly, net of
collections made from customers. Fees related to the sales of receivables under
this program, which are allocated from Occidental, were $8.4 million, $6.8
million and $8.3 million for the years ended December 31, 1997, 1996 and 1995,
respectively, and are included in other expense, net.

   Under the terms of the Equistar agreement, Occidental repurchased net
domestic trade receivables of $114.8 million of the Occidental Contributed
Business as of May 15, 1998 and contributed $100.3 million to Equistar.

   Other receivables include $3.9 million and $1.7 million as of December 31,
1997 and 1996, respectively, from the equity investee.

(4) INVENTORIES--

(5) EQUITY INVESTMENT--

   The Occidental Contributed Business has a fifty percent interest in PD
Glycol, a partnership which manufactures ethylene oxide and ethylene glycol
derivatives at its plant in Beaumont, Texas. The investment, which is accounted
for on the equity method, exceeded the historical underlying equity in net
assets by approximately $43 million at December 31, 1997 and $44 million at
December 31, 1996. The excess is being amortized into income over the estimated
total productive life of the plant.

(6) PROPERTY, PLANT AND EQUIPMENT--

   Property additions and major renewals and improvements are capitalized at
cost. Property acquired under a capital lease has been capitalized at the
present value of future minimum lease payments. Depreciation is primarily
provided using the units-of-production method based on estimated total
productive life.

   Interest costs incurred in connection with major capital expenditures are
capitalized and amortized over the lives of the related assets. Capitalized
interest is calculated based on the average borrowing rate of Occidental. The
amount of interest capitalized was $637,000 and $639,000 for the years ended
December 31, 1997 and 1996, respectively.

   Property, plant and equipment consists of the following (in thousands):

</TABLE>

   Catalyst is amortized over estimated lives ranging from 18 months to 3
years. Deferred start-up costs are amortized over a period of 20 years. Other
amortizable assets are written off to income over the estimated periods to be
benefited.

   In April 1998, the American Institute of Certified Public Accountants issued
Statement of Position 98-5, "Reporting on the Costs of Start-Up Activities"
(SOP 98-5), which requires that costs of start-up activities, including
organizational costs, be expensed as incurred. The initial application of the
statement will result in a charge to income for any costs of start-up
activities that have not yet been fully amortized. Occidental will implement
SOP 98-5 effective January 1, 1999.

</TABLE>

   Maintenance turnarounds are generally performed every 2 to 5 years.
Occidental utilizes an accrual methodology under which it estimates the project
cost of a turnaround and accrues the cost equally over the years between
turnarounds. Total accruals relating to these future major maintenance projects
were $41.2 million and $22.1 million as of December 31, 1997 and 1996,
respectively, and were included in accrued liabilities as noted above and
deferred credits and other liabilities in the accompanying Balance Sheets.

(9) NOTES PAYABLE TO AFFILIATES--

   The financial statements of the Occidental Contributed Business include
several notes payable to Occidental and an affiliate. Accrued interest on these
notes is settled annually through and is included in invested capital at rates
ranging between 6 and 11 percent. Interest expense on notes payable to
affiliates was $93.4 million, $105.8 million and $137.1 million for the years
ended December 31, 1997, 1996 and 1995.

   Principal amounts of the notes payable to an affiliate totaling $63.9
million are due on December 31, 1998. As the amounts will be settled either
through invested capital or another note payable to the affiliate, no notes
payable to affiliates have been classified as current in the accompanying
Balance Sheets.

(10) RETIREMENT PLANS AND POSTRETIREMENT BENEFITS--

   The Occidental Contributed Business participates in various defined
contribution retirement plans sponsored by Occidental for its salaried,
domestic union and nonunion hourly employees that provide for periodic
contributions by the Occidental Contributed Business based on plan-specific
criteria, such as base pay, age level, and/or employee contributions. The
Occidental Contributed Business contributed and expensed approximately $6
million under the provisions of these plans in each of the years 1997, 1996 and
1995.

   Occidental provides medical and dental benefits and life insurance coverage
for certain active, retired and disabled employees and their eligible
dependents. Beginning in 1993, certain salaried participants pay for all
medical cost increases in excess of increases in the Consumer Price Index
(CPI). The benefits generally are funded by Occidental as the benefits are paid
during the year. The cost of providing these benefits is based on claims filed
and insurance premiums paid for the period.

   The Occidental Contributed Business' retirement and postretirement defined
benefit plans are accrued based on various assumptions and discount rates, as
described below. The actuarial assumptions used could change in the near term
as a result of changes in expected future trends and other factors which,
depending on the nature of the changes, could cause increases or decreases in
the liabilities accrued.

 Retirement plans--

   Pension costs for the Occidental Contributed Business' defined benefit
pension plans, determined by independent actuarial valuations, are funded by
payments to trust funds, which are administered by independent

   In 1997 and 1996, the Occidental Contributed Business recorded an adjustment

the net-of-tax difference between the additional liability required under
pension accounting provisions and the corresponding intangible asset.

(a) A related amount up to the limit allowable under SFAS No. 87 "Employers'
    Accounting for Pensions" has been included in other assets. Amounts
    exceeding such limits have been charged to invested capital.

   The discount rate used in determining the actuarial present value of the
projected benefit obligations was 7.5 percent in 1997 and 1996. The rate of
increase in future compensation levels used in determining the actuarial
present value of the projected benefit obligations was between 4.5 and 5.5
percent in 1997 and 1996. The expected long-term rate of return on assets was 8
percent in 1997 and 1996.

 Postretirement benefits--

   To reflect the Occidental Contributed Business' participation in the
Occidental plan, the net periodic postretirement benefit costs and the
postretirement benefit obligations are based on an allocation of the Occidental
actuarial study using participant counts and demographic information for the
Occidental Contributed Business for each of the years presented in the tables
below.

   The postretirement benefit obligation as of December 31, 1997 was determined
by application of the terms of medical and dental benefits and life insurance
coverage, including the effect of established maximums on

covered costs, together with relevant actuarial assumptions and health care
cost trend rates projected at a CPI increase of 3 percent in 1997 (except for
union employees). For union employees, the health care cost trend rates were
projected at annual rates ranging ratably from 8.5 percent in 1997 to 5 percent
through the year 2004 and level thereafter. The effect of a one percent annual
increase in these assumed cost trend rates would increase the accumulated
postretirement benefit obligation by approximately $800,000 and the annual
service and interest costs by approximately $100,000 in 1997. The weighted
average discount rate used in determining the accumulated postretirement
benefit obligation as of December 31, 1997 was 7.5 percent. The plans are
unfunded.

   Rental expense for operating leases, excluding leases with terms of one year
or less, was approximately $17 million, $17 million and $18 million for the
years ended December 31, 1997, 1996 and 1995, respectively.

(12) COMMITMENTS AND CONTINGENCIES--

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

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

   Under the terms of the agreement with Equistar, Occidental has agreed to
indemnify Equistar for any present or future contingent liabilities arising
within a seven year period after May 15, 1998 which are attributable to the
Occidental Contributed Business's operations prior to May 15, 1998 in excess of
$7 million.

   The Occidental Contributed Business has certain other commitments to
purchase electrical power, raw materials and other potential obligations, all
in the ordinary course of business.

(13) SUBSEQUENT EVENT--

   On January 11, 1999, CITGO Petroleum Corporation (CITGO) initiated a legal
action against Occidental Chemical Corporation (OCC) in the United States
District Court for the Northern District of Oklahoma seeking compensatory and
exemplary damages in an unspecified amount. It alleges that OCC breached the
provisions of a Plant Site Right of First Refusal Agreement pertaining to the
Lake Charles plant dated August 31, 1983, between CITGO and Cities Service Oil
and Gas Corporation, predecessor in interest to OCC. It is impossible at this
time to determine any ultimate legal liabilities that may arise from this
lawsuit. The CITGO complaint was not filed against Equistar and seeks only
money damages from OCC. In management's opinion, the lawsuit is not likely to
have a material adverse effect upon the financial position of the Occidental
Contributed Business.

                NOTES TO CONSOLIDATED BALANCE SHEET (UNAUDITED)

1. Basis of Preparation

   The accompanying unaudited consolidated financial statements have been
prepared in accordance with generally accepted accounting principles for
interim financial information and with the instructions to Form 10-Q and Rule
10-01 of Regulation S-X. Accordingly, they do not include all of the
information and footnotes required by generally accepted accounting principles
for complete financial statements. In the opinion of management, all
adjustments, consisting only of normal, recurring adjustments considered
necessary for a fair presentation, have been included. For further information,
refer to the Consolidated Financial Statements and notes thereto for the year
ended December 31, 1998 included in the Lyondell Chemical Company ("Company" or
"Lyondell") 1998 Annual Report on Form 10-K pursuant to Section 13 or 15(d) of
the Securities Exchange Act of 1934 which has been filed with the Securities
and Exchange Commission.

2. Company Operations

   During the third quarter 1998, Lyondell acquired ARCO Chemical (the
"Acquired Business" or the "Acquisition"), the world's largest producer of
propylene oxide ("PO") and a leading worldwide producer and marketer of
polyether polyols, propylene glycol ("PG"), propylene glycol ethers ("PGE"),
toluene diisocyanate ("TDI"), styrene monomer ("SM") and methyl tertiary butyl
ether ("MTBE"). The Acquired Business is reported as the intermediate chemicals
and derivatives segment.

   The Company's operations in the petrochemicals and polymers segments are
conducted through its joint venture ownership interest in Equistar Chemicals,
LP ("Equistar"). The balance sheet of Lyondell at June 30, 1999 and notes
thereto is presented because Lyondell guarantees to Equistar certain
obligations of Lyondell's subsidiary that serves as a general partner of
Equistar (see Note 3).

   Equistar's petrochemicals segment consists of: olefins, including ethylene,
propylene, butadiene, butylenes and specialty products; aromatics, including
benzene and toluene; oxygenated chemicals, including ethylene oxide and
derivatives, MTBE, ethyl alcohol and diethyl ether; and specialty chemicals,
including refinery blending stocks.

   Equistar's polymers segment consists of: polyolefins, including high density
polyethylene ("HDPE"), low density polyethylene ("LDPE"), linear low density
polyethylene ("LLDPE") and polypropylene; and performance polymers products,
including color concentrates and compounds, wire and cable resins and
compounds; adhesive resins; and fine powders. The color concentrates and
compounds business was sold on April 30, 1999.

   The Company's operations in the refining segment are conducted through its
joint venture ownership interest in LYONDELL-CITGO Refining LP ("LCR") (see
Note 4). This segment consists of: refined petroleum products, including
conventional and reformulated gasoline, low sulfur diesel and jet fuel;
aromatics produced at LCR's full-conversion Houston, Texas refinery (the
"Refinery"), including benzene, toluene, paraxylene and orthoxylene;
lubricants, including industrial lubricants, motor oils, white oils, process
oils and base oils; carbon black oil; sulfur; residual oil; petroleum coke
fuel; olefins feedstocks; and crude oil resales. LCR sells its principal
refined products to the Company's joint venture partner in LCR, CITGO Petroleum
Corporation ("CITGO").

   The Company has additional operations conducted through its joint venture
ownership interest in Lyondell Methanol Company, L.P. ("LMC"). These operations
consist of methanol and other petrochemical products produced by its methanol
facility.

3. Equity Interest in Equistar Chemicals, LP

   Equistar was formed on December 1, 1997 as a joint venture between the
Company and Millennium Chemicals Inc. ("Millennium"), to own and operate the
businesses contributed by the partners. Lyondell contributed substantially all
of the assets comprising its petrochemicals and polymers business segments,
while Millennium contributed substantially all of the assets comprising its
polyethylene and related products, performance polymers and ethyl alcohol
businesses, which had been held in Millennium Petrochemicals, Inc., a wholly-
owned subsidiary of Millennium. On May 15, 1998, the ethylene, propylene and
ethylene oxide and derivatives businesses of Occidental Chemical Corporation
(the "Occidental Contributed Business"), a subsidiary of Occidental Petroleum
Corporation ("Occidental"), were contributed to Equistar. The joint venture is
structured as a Delaware limited partnership owned by subsidiaries of the
Company, Millennium and Occidental (the "Partners").

   Lyondell currently has a 41.0 percent joint venture ownership interest in
Equistar, while Millennium and Occidental each have 29.5 percent. Prior to the
addition of Occidental as a partner on May 15, 1998, the Company had a 57.0
percent joint venture ownership interest, while Millennium had 43.0 percent.
Because the Partners jointly control certain management decisions, Lyondell
accounts for its investment in Equistar using the equity method of accounting.

   A subsidiary of the Company, Lyondell Petrochemical G.P. Inc. ("General
Partner") holds a 0.82% general partner interest in Equistar.

   The General Partner has no independent operations of its own and certain of
its obligations as general partner have, under an agreement signed between the
Company and Equistar, been guaranteed by the Company. Accordingly, the balance
sheet of the Company, as guarantor of certain of the General Partner's
obligations, is presented at June 30, 1999. The General Partner had assets
consisting of its investment in Equistar of ($9) and invested capital, after
intercompany balances, of $9. The credit balance in the investment account is
due to the fact that the initial contribution of assets to Equistar was made by
Lyondell Petrochemical L.P. Inc. ("Limited Partner") and not allocated between
the General Partner and the Limited Partner. The investment account on the
General Partner's books reflects their proportionate share of income and
distributions from Equistar.

   Summarized financial information for Equistar is as follows as of June 30,
1999:

7. Long-Term Debt

   During May 1999, Lyondell amended its $7 billion Credit Facility. The Credit
Facility amendments provided the lenders with additional collateral, re-priced
the existing loans to reflect then market rates and revised certain financial
covenants. Also in May 1999, Lyondell issued 40.25 million shares of common
stock, receiving net proceeds of $736 million. Lyondell also issued $500
million of senior subordinated notes and $1.9 billion of senior secured notes
(collectively, the "New Notes"). Lyondell borrowed additional amounts under the
amended Credit Facility through the Credit Facility's new $850 million, seven-
year Term Loan E and the Credit Facility's new $150 million Term Loan F,
maturing December 31, 2003. Lyondell used the proceeds to retire the $1.25
billion principal amount of Term Loan C, maturing June 30, 1999, and the $2
billion principal of Term Loan D, maturing June 30, 2000, and to partially
repay principal under Term Loans A and B under the Credit Facility.

   The amended Credit Facility requires Lyondell to issue $470 million of
subordinated notes (or more junior securities) by June 2002. The requirement to
issue $470 million of subordinated notes will be reduced by $2 for each $1 of
equity securities issued by Lyondell, and will be eliminated if Lyondell
achieves either (1) a specified total debt to adjusted EBITDA ratio, as
defined, or (2) a specified credit rating for its senior unsecured debt.

   Under the covenant provisions of the amended Credit Facility, Lyondell has
agreed to, among other things, (i) maintain certain specified financial ratios
and consolidated net worth (as defined in the Credit facility), (ii) refrain
from making certain distributions with respect to Lyondell's capital stock,
(iii) refrain from making certain investments, as defined, (iv) refrain from
allowing its subsidiaries to incur certain types and amounts of debt, and (v)
use its best efforts to maintain certain ownership interests in its joint
ventures and to ensure that the joint ventures maintain certain capital
expenditure and debt levels and cash distribution policies.

   The indentures under which the "New Notes" were issued contain covenants
that restrict the ability of Lyondell and its subsidiaries to (i) incur
additional debt or issue subsidiary preferred stock, (ii) increase dividends on
Lyondell capital stock, (iii) redeem or repurchase capital stock or repurchase
subordinated debt, (iv) engage in transactions with affiliates, except on an
arms-length basis, (v) create liens or engage in sale and leaseback
transactions, (vi) make some types of investments and sell assets, and (vii)
consolidate or merge with, or sell substantially all of its assets to, another
person. Some of the covenants will no longer apply if the notes achieve
specified credit ratings. The notes are unconditionally guaranteed by certain
Lyondell subsidiaries.

8. Commitments and Contingencies

   The Company has commitments, including those related to capital
expenditures, all made in the normal course of business. During August 1998, as
contemplated at the time of the Acquisition, Lyondell announced the delay of
construction of a PO plant, known as PO-11, that ARCO Chemical had previously
scheduled for startup in late 2001. As part of the delay, the Company is
negotiating the cancellation of the related lump-sum contract for the
engineering, procurement and construction of the PO-11 plant. The Company
recorded estimated liabilities for penalties and cancellation charges related
to the cancellation of the lump-sum contract and related commitments at the
time of the Acquisition.

   The Acquired Business is party to a long-term supply arrangement for TDI.
Under the arrangement, the Company is entitled to all of the TDI output of the
supplier's two plants in France, which have a combined rated capacity of
approximately 264 million pounds per year. The Company is required to purchase
a minimum of 216 million pounds of TDI per year for up to 15 years, beginning
January 1, 1995. The aggregate purchase price is a combination of plant cost
and market price. The Company is further obligated to pay additional capacity
reservation fees based upon plant output factors.

   Crude Supply Agreement--LCR has a long-term crude supply agreement ("Crude
Supply Agreement") with Lagoven, S.A., now known as PDVSA Petroleo y Gas, S.A.
("PDVSA Oil"), an affiliate of CITGO. Under the Crude Supply Agreement, LCR is
required to purchase, and PDVSA Oil is required to sell, up to 230,000 barrels
per day of extra heavy Venezuelan crude oil. PDVSA Oil has the right, but not
the obligation, to supply incremental amounts above 230,000 barrels per day.
Depending upon market conditions, breach or termination of LCR's Crude Supply
Agreement could adversely affect LCR, and therefore, the Company. In the

                                      F-83
<PAGE>

                           LYONDELL CHEMICAL COMPANY

          NOTES TO CONSOLIDATED BALANCE SHEET (UNAUDITED)--(Continued)

event of certain force majeure conditions, including governmental or other
actions restricting or otherwise limiting PDVSA Oil's ability to perform its
obligations, LCR would seek alternative crude supply arrangements. Any such
alternative arrangements may not be as beneficial as the Crude Supply
Agreement. There can be no assurance that alternative crude oils with similar
margins would be available for purchase by LCR. Furthermore, the breach or
termination of the Crude Supply Agreement would require LCR to return to the
practice of purchasing all or a portion of its crude oil feedstocks in the
merchant market and would again subject LCR to significant volatility and price
fluctuations.

   In late April 1998, LCR received notification from PDVSA Oil of reduced
delivery of crude oil related to announced OPEC production cuts. LCR began
receiving the reduced allocation of crude oil from PDVSA Oil in August 1998.
Following the March 1999 OPEC agreement to limit production, LCR was advised by
PDVSA Oil in May 1999 of a further reduction in the allocation of crude oil
supplied under the Crude Supply Agreement.

   Cross Indemnity Agreement--In connection with the transfer of assets and
liabilities from Atlantic Richfield Company ("ARCO") to the Company in 1988,
the Company agreed to assume certain liabilities arising out of the operation
of the Company's integrated petrochemicals and refining business prior to July
1, 1988. In connection with the transfer of such liabilities, the Company and
ARCO entered into an agreement, updated in 1997 ("Revised Cross-Indemnity
Agreement"), whereby the Company agreed to defend and indemnify ARCO against
certain uninsured claims and liabilities which ARCO may incur relating to the
operation of the business of the Company prior to July 1, 1988, including
certain liabilities which may arise out of pending and future lawsuits. For
current and future cases related to Company products and Company operations,
ARCO and the Company bear a proportionate share of judgment and settlement
costs according to a formula that allocates responsibility based upon years of
ownership during the relevant time period. The party with the more significant
potential liability exposure is responsible for case management and associated
costs while allowing the non-case managing party to protect its interests.
Under the Revised Cross-Indemnity Agreement, the Company will assume
responsibility for its proportionate share of future costs for waste site
matters not covered by ARCO insurance. Subject to the uncertainty inherent in
all litigation, management believes the resolution of the matters pursuant to
the Revised Cross-Indemnity Agreement will not have a material adverse effect
upon the Consolidated Financial Statements of the Company.

   In connection with the Acquisition, the Company succeeded, indirectly, to a
cross indemnity agreement with ARCO whereby ARCO Chemical indemnified ARCO
against certain claims or liabilities that ARCO may incur relating to ARCO's
former ownership and operation of the businesses of ARCO Chemical ("Former ARCO
Businesses"), including liabilities under laws relating to the protection of
the environment and the workplace, and liabilities arising out of certain
litigation. As part of the agreement, ARCO indemnified ARCO Chemical with
respect to claims or liabilities and other matters of litigation not related to
the Former ARCO Businesses. ARCO also indemnified ARCO Chemical for certain
federal, foreign, state, and local taxes that might be assessed upon audit of
the operations of the Former ARCO Businesses for periods prior to July 1, 1987.

   Indemnification Arrangements Relating to Equistar--Lyondell, Millennium and
Occidental have each agreed to provide certain indemnifications to Equistar
with respect to the petrochemicals and polymers businesses contributed by the
Partners. In addition, Equistar agreed to assume third party claims that are
related to certain pre-closing contingent liabilities asserted prior to
December 1, 2004 for Lyondell and Millennium, and May 15, 2005 for Occidental,
to the extent the aggregate thereof does not exceed $7 million to each Partner,
subject to certain terms of the respective Asset Contribution Agreements. From
inception through June 30, 1999, Equistar expensed approximately $3 million
under the $7 million indemnification basket with respect to the business
contributed by Lyondell.

          NOTES TO CONSOLIDATED BALANCE SHEET (UNAUDITED)--(Continued)


   Environmental--The Company's policy is to be in compliance with all
applicable environmental laws. The Company is subject to extensive
environmental laws and regulations concerning emissions to the air, discharges
to surface and subsurface waters and the generation, handling, storage,
transportation, treatment and disposal of waste materials. Some of these laws
and regulations are subject to varying and conflicting interpretations. In
addition, the Company cannot accurately predict future developments, such as
increasingly strict environmental laws and inspection and enforcement policies,
as well as higher compliance costs arising therefrom, which might affect the
handling, manufacture, use, emission or disposal of products, other materials
or hazardous and non-hazardous waste.

   Pursuant to the terms of the Revised Cross-Indemnity Agreement, the Company
is currently contributing funds to the clean up of one waste site (Brio,
located near Houston, Texas) under the Comprehensive Environmental Response,
Compensation and Liability Act ("CERCLA") as amended and the Superfund
Amendments and Reauthorization Act of 1986. The Company is also subject to
certain assessment and remedial actions at the Refinery under the Resource
Conservation and Recovery Act ("RCRA"). In addition, the Company has negotiated
an order with the Texas Natural Resource Conservation Commission ("TNRCC") for
assessment and remediation of groundwater and soil contamination at the
Refinery.

   As of June 30, 1999, the Company has accrued $8 million related to future
CERCLA, RCRA and TNRCC assessment and remediation costs associated with the
above mentioned sites. The costs are expected to be incurred over the next two
to seven years. In the opinion of management, there is currently no material
range of loss in excess of the amount recorded for these sites. However, it is
possible that new information about the sites for which the reserve has been
established, new technology or future developments such as involvement in other
CERCLA, RCRA, TNRCC or other comparable state law investigations, could require
the Company to reassess its potential exposure related to environmental
matters.

   As part of the Acquisition, the Company assumed ARCO Chemical's
environmental liability, which had a remaining balance of $36 million at June
30, 1999 and reflects the Company's latest assessment of potential future
remediation costs associated with known ARCO Chemical sites. The liability is
related to five current plant sites, one former plant site and one federal
Superfund site for amounts ranging from $1 million to $18 million per site.
Further, the Acquired Business is involved in administrative proceedings or
lawsuits relating to a minimal number of other Superfund sites. The Company
estimates however, based upon currently available information, that potential
loss contingencies associated with these Superfund sites, individually and in
the aggregate, are not significant. Substantially all amounts accrued are
expected to be paid out over the next five to ten years.

   The Company has relied upon remedial investigation/feasibility studies
("RI/FS") at each site of the Acquired Business as a basis for estimating
remediation costs at the site. RI/FS or preliminary assessments have been
completed at most of the sites. However, selection of the remediation method
and the cleanup standard to be applied are, in most cases, subject to approval
by the appropriate government authority. Accordingly, the Company may have
possible loss contingencies in excess of the amounts accrued to the extent the
scope of remediation required, the final remediation method selected and/or the
cleanup standard applied, vary from the assumptions used in estimating the
liability. The Company estimates that the upper range of these possible loss
contingencies should not exceed the amount accrued by more than $65 million.

   The extent of loss related to environmental matters ultimately depends upon
a number of factors, including technological developments, changes in
environmental laws, the number and ability to pay of other parties involved at
a particular site and the Company's potential involvement in additional
environmental assessments and cleanups. Based upon currently known facts,
management believes that any remediation costs the Company may incur in excess
of the amounts accrued or disclosed above would not have a material adverse
impact on the Company's Consolidated Financial Statements.

          NOTES TO CONSOLIDATED BALANCE SHEET (UNAUDITED)--(Continued)


   MTBE--Certain federal and state legislative initiatives have sought either
to rescind the oxygenate requirement for reformulated gasoline or to restrict
the use of MTBE. At the state level, these initiatives include the recent
affirmation by the California State Energy Commission of Governor Gray Davis'
December 2002 deadline for the removal of MTBE from California gasoline
supplies and approval of an MTBE phase out timetable. At the federal level, the
blue ribbon panel appointed by the Environmental Protection Agency issued its
report on July 27, 1999. That report recommended, among other things, reducing
the use of MTBE in gasoline. Based on that report, the Environmental Protection
Agency has recently indicated that it will recommend congress amend the Clean
Air Act to reduce MTBE in reformulated gasoline. In addition, on August 9,
1999, the U.S. Senate passed a "Sense of the Senate" resolution calling for
removal of MTBE from gasoline. These initiatives or other governmental actions
could result in a significant reduction in the Company's MTBE sales. In
addition, the Company has a take-or-pay contract with ARCO, which contributes
significant pretax margin. If legislation is enacted or other governmental
action taken, ARCO has indicated that it might attempt to invoke a force
majeure provision in the contract in order to reduce the quantities of MTBE in
purchases under, or to terminate, the contract. The Company would vigorously
dispute such action.

   General--The Company is involved in various lawsuits and proceedings.
Subject to the uncertainty inherent in all litigation, management believes the
resolution of these proceedings will not have a material adverse effect upon
the Consolidated Financial Statements of the Company.

   In the opinion of management, any liability arising from the matters
discussed in this Note is not expected to have a material adverse effect on the
Consolidated Financial Statements of the Company. However, the adverse
resolution in any reporting period of one or more of these matters discussed in
this Note could have a material impact on the Company's results of operations
for that period without giving effect to contribution or indemnification
obligations of co-defendants or others, or to the effect of any insurance
coverage that may be available to offset the effects of any such award.

9. Stockholders' Equity

   Common Stock--In May 1999, Lyondell issued 40.25 million shares of common
stock at $19 per share. The net proceeds of $736 million were credited to
"Common stock" and "Additional paid in capital" in the Consolidated Balance
Sheet. Common stock outstanding increased from 77.0 million shares at December
31, 1998 to 117.5 million shares at June 30, 1999.

10. Purchase of ARCO Chemical Company

   As of July 28, 1998, the Company completed its acquisition of ARCO Chemical.
In connection with the Acquisition, the Company accrued liabilities for costs
associated with the delay of construction of the PO-11 plant, vesting of
certain key manager benefits pursuant to a change of control provision,
severance costs for the involuntary termination of certain headquarters
employees, and relocation costs for moving personnel to the Company's Houston
headquarters. The liability totaled approximately $255 million at the date of
acquisition. Through June 30, 1999, the Company had paid and charged
approximately $140 million against the accrued liability.

1. Description of the Company and Operations

   Lyondell Chemical Company ("Company" or "Lyondell"), formerly Lyondell
Petrochemical Company, operates in the (i) intermediate chemicals and
derivatives, (ii) petrochemicals, (iii) polymers, (iv) refining and (v)
methanol businesses through its wholly owned subsidiary, ARCO Chemical Company
("ARCO Chemical" or "Acquired Business"), acquired by the Company as of July
28, 1998 (see Note 3), and through the Company's joint venture ownership
interests in Equistar Chemicals, LP ("Equistar"), LYONDELL-CITGO Refining LP
("LCR"), formerly LYONDELL-CITGO Refining Company Ltd., and Lyondell Methanol
Company, L.P. ("Lyondell Methanol").

   The Acquired Business, now named Lyondell Chemical Worldwide, Inc., is the
world's largest producer of propylene oxide ("PO") and a leading worldwide
producer and marketer of polyether polyols, propylene glycol, propylene glycol
ethers, toluene diisocyanate ("TDI"), styrene monomer ("SM") and methyl
tertiary butyl ether ("MTBE"). The Acquired Business is reported as the
intermediate chemicals and derivatives segment.

   The Company's operations in the petrochemicals and polymers segments are
conducted through its joint venture ownership interest in Equistar (see Note
4). The Company accounts for its investment in Equistar using the equity method
of accounting. Prior to the formation of Equistar on December 1, 1997, the
Company's assets and operations of the petrochemicals and polymers businesses
were fully consolidated in the consolidated financial statements of the
Company. The balance sheet of Lyondell at December 31, 1998 and notes thereto
is presented because Lyondell guarantees to Equistar certain obligations of
Lyondell's subsidiary that serves as a general partner of Equistar (see Note
4).

   Equistar's petrochemicals division consists of: olefins, including ethylene,
propylene, butadiene, butylenes and specialty products; aromatics, including
benzene and toluene; oxygenated chemicals, including ethylene oxide and
derivatives, MTBE, ethyl alcohol and diethyl ether; and specialty chemicals,
including refinery blending stocks.

   Equistar's polymers division consists of: polyolefins, including high
density polyethylene ("HDPE"), low density polyethylene ("LDPE"), linear-low
density polyethylene ("LLDPE") and polypropylene; and performance polymers
products, including color concentrates and compounds, wire and cable resins and
compounds, adhesive resins, and fine powders.

   The Company's operations in the refining segment are conducted through its
joint venture ownership interest in LCR (see Note 5). This segment consists of:
refined petroleum products, including conventional and reformulated gasoline,
low sulfur diesel and jet fuel; aromatics produced at LCR's full-conversion
Houston, Texas refinery ("Refinery"), including benzene, toluene, paraxylene
and orthoxylene; lubricants, including industrial lubricants, motor oils, white
oils, process oils and base oils; carbon black oil; sulfur; residual oil;
petroleum coke fuel; olefins feedstocks; and crude oil resales. LCR sells its
principal refined products to the Company's joint venture partner in LCR, CITGO
Petroleum Corporation ("CITGO").

   The Company has additional operations conducted through its joint venture
ownership interest in Lyondell Methanol (see Note 6). These operations consist
of methanol and other petrochemical products produced by its methanol facility.
Effective January 1, 1998, Lyondell began to account for its investment in
Lyondell Methanol using the equity method of accounting. Prior to 1998,
Lyondell Methanol's assets and operations were fully consolidated in the
consolidated financial statements.

                NOTES TO CONSOLIDATED BALANCE SHEET--(Continued)


2. Summary of Significant Accounting Policies

   Basis of Presentation--The 1998 Consolidated Balance Sheet includes the
accounts of the Company and its subsidiaries, including the results of
operations of the Acquired Business for the five months ended December 31,
1998. The Company's joint venture ownership interests in Equistar LCR, and
Lyondell Methanol, are reported as equity investments and are not consolidated
into the Company's financial statements. Additionally, the Company has an
investment in a 50 percent owned affiliate that is accounted for using the
equity method of accounting. All significant transactions between the entities
of the Company have been eliminated from the Consolidated Balance Sheet.

   Equity Method of Accounting--Investments in joint ventures ("JVs") where the
Company exerts a certain minimum level of management control, but lacks full
decision making ability over all major issues, are accounted for using the
equity method of accounting. Under those circumstances, this accounting
treatment is used even though the Company's ownership percentage may exceed 50
percent. Under this method, the operations of the JVs are not consolidated line
by line with those of the Company. Instead, the Company's portion of the JVs'
net assets appears in the Consolidated Balance Sheet as "Investment in
affiliates."

   Cash and Cash Equivalents--Cash equivalents consist of highly liquid debt
instruments such as certificates of deposit, commercial paper and money market
accounts purchased with an original maturity date of three months or less. Cash
equivalents are stated at cost, which approximates fair value. The Company's
policy is to invest cash in conservative, highly rated instruments and limit
the amount of credit exposure to any one institution. The Company performs
periodic evaluations of the relative credit standing of these financial
institutions, which are considered in the Company's investment strategy.

   The Company has no requirements for compensating balances in a specific
amount at a specific point in time. The Company does maintain compensating
balances for some of its banking services and products. Such balances are
maintained on an average basis and are solely at the Company's discretion. As a
result, none of the Company's cash is restricted.

   Accounts Receivable--The Company sells its products primarily to other
industrial concerns in the petrochemicals and refining industries. The Company
performs ongoing credit evaluations of its customers' financial condition, and,
in certain circumstances, requires letters of credit from them. The Company's
allowance for doubtful accounts receivable, which is reflected in the
Consolidated Balance Sheet as a reduction of accounts receivable, totaled $11
million at December 31, 1998.

   Property, Plant and Equipment--Property, plant and equipment are recorded at
cost. Depreciation of manufacturing facilities and equipment is computed using
the straight-line method over the estimated useful lives of the related assets
ranging from 5 to 30 years.

   Upon retirement or sale, the Company removes the cost of the asset and the
related accumulated depreciation from the accounts and reflects any resulting
gain or loss in the Consolidated Statements of Income. The Company's policy is
to capitalize interest cost incurred on debt during the construction of major
projects exceeding one year.

   Turnaround Maintenance and Repair Expenses--Cost of repairs and maintenance
incurred in connection with turnarounds of major units at the Company's
manufacturing facilities exceeding $5 million are deferred and amortized using
the straight-line method, until the next planned turnaround, generally four to
six years.

<PAGE>

                           LYONDELL CHEMICAL COMPANY

                NOTES TO CONSOLIDATED BALANCE SHEET--(Continued)


   Goodwill--Goodwill represents the excess of purchase price paid over the
value assigned to the net tangible assets of a business acquired. This
intangible asset is amortized over 40 years, the estimated useful life, using
the straight-line method. See Long-Lived Asset Impairment below.

   Deferred Charges--Deferred charges are carried at cost and consist primarily
of the value assigned to patents and licensed technology, capacity reservation
fees and other long-term processing rights and costs. These assets are
amortized using the straight-line method over their estimated useful lives or
the term of the related agreement, if shorter.

   Environmental Remediation Costs--Expenditures related to investigation and
remediation of contaminated sites, which include operating facilities and waste
disposal sites, are accrued when it is probable a liability has been incurred
and the amount of the liability can reasonably be estimated. Estimates have not
been discounted to present value. Environmental remediation costs are expensed
or capitalized in accordance with generally accepted accounting principles.

   Pension and Other Postretirement Benefit Plans--During 1998, the Company
adopted Statement of Financial Accounting Standards ("SFAS") No. 132,
Employers' Disclosures about Pensions and Other Retirement Benefits. The
provisions of SFAS No. 132 revise employer disclosures about pension and other
postretirement benefit plans. It does not change the measurement or recognition
of these plans. SFAS No. 132 standardizes the disclosure requirements for these
plans, to the extent practicable.

   Minority Interest--Minority interest in 1998 primarily represents the
interest of third-party investors in a partnership that owns one of the
Company's two domestic PO/SM plants. The Company retains a majority interest in
the partnership.

   Exchanges--Crude oil and finished product exchange transactions, which
involve homogeneous commodities in the same line of business and do not involve
the payment or receipt of cash, are not accounted for as purchases and sales.
Any resulting volumetric exchange balances are accounted for as inventory in
accordance with the normal LIFO valuation policy.

   Income Taxes--Deferred income taxes result from temporary differences in the
recognition of revenues and expenses for tax and financial reporting purposes
and are calculated based upon cumulative book and tax differences in the
Consolidated Balance Sheet in accordance with SFAS No. 109, Accounting for
Income Taxes. Valuation allowances are provided against deferred tax assets
which are not likely to be realized in full.

   Foreign Currency Translation--Where the local currency is the functional
currency, the financial statements of international operations are translated
into U.S. dollars using the exchange rate at each balance sheet date for assets
and liabilities. Translation adjustments are recorded as a separate component
of "Accumulated other comprehensive income" in the stockholders' equity section
of the Consolidated Balance Sheet.

   Use of Estimates--The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities, the
disclosure of contingent assets and liabilities at the date of the financial
statements, and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

   Long-Lived Asset Impairment--In accordance with SFAS No. 121, Accounting for
the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed
Of, the Company reviews its long-lived assets,

                                      F-91

                           LYONDELL CHEMICAL COMPANY

                NOTES TO CONSOLIDATED BALANCE SHEET--(Continued)

including goodwill, for impairment on an exception basis whenever events or
changes in circumstances indicate a potential loss in utility.

3. Purchase of ARCO Chemical Company

   As of July 28, 1998, the Company completed its acquisition of ARCO Chemical
("Acquisition"). The transaction was financed through a $7.0 billion Credit
Facility (see Note 14). This Acquisition was accounted for using the purchase
method of accounting. The acquisition cost of approximately $5.9 billion has
been allocated to the assets acquired and liabilities assumed based upon the
estimated fair value of such assets and liabilities at the date of acquisition.
The Company is awaiting additional information related to the fair value of
certain assets acquired and liabilities assumed. Management does not expect the
finalization of these matters to have a material effect on the purchase price
allocation. In connection with the acquisition, the Company accrued liabilities
for costs associated with the delay of construction of the PO-11 plant, vesting
of certain key manager benefits pursuant to a change of control provision,
severance costs for the involuntary termination of certain headquarters
employees, and relocation costs for moving personnel to the Company's Houston
headquarters. The liability totaled $255 million at the date of acquisition.
Through December 31, 1998, the Company had paid and charged approximately $132
million against the liability.

   Approximately $57 million, or less than one percent of the purchase price,
was allocated to purchased in-process research and development. This included
three projects valued at $29 million, $18 million and $10 million,
respectively, representing two new product applications and one new process
technology. The activities represented by these projects will be continued by
the Company and the values assigned represent intangibles with no alternative
future use. Accordingly, the Company wrote off the in-process research and
development, recording a nonrecurring charge of $57 million in the third
quarter 1998 (see Note 7). The excess of purchase price paid over the estimated
fair value of net assets acquired was allocated to goodwill. The amount
allocated to goodwill was approximately $1.4 billion and is being amortized,
using the straight-line method, over 40 years, the estimated useful life.

   The fair value of the assets acquired and liabilities assumed, net of cash
acquired, was as follows:

4. Equity Interest in Equistar Chemicals, LP

   Equistar was formed on December 1, 1997 as a joint venture between the
Company and Millennium Chemicals Inc. ("Millennium"), to own and operate the
businesses contributed by the partners. Lyondell contributed substantially all
of the assets comprising its petrochemicals and polymers business segments,
while Millennium contributed substantially all of the assets comprising its
polyethylene and related products, performance polymers and ethyl alcohol
businesses, which had been held in Millennium Petrochemicals Inc., a wholly-
owned subsidiary of Millennium. On May 15, 1998, the ethylene, propylene and
ethylene oxide and derivatives businesses of Occidental Chemical Corporation, a
subsidiary of Occidental Petroleum Corporation

                NOTES TO CONSOLIDATED BALANCE SHEET--(Continued)

("Occidental"), were contributed to Equistar ("Occidental Contributed
Business"). Equistar is operated as a Delaware limited partnership owned by
subsidiaries of the Company, Millennium and Occidental ("Partners").

   Lyondell currently has a 41.0 percent joint venture ownership interest,
while Millennium and Occidental each have 29.5 percent. Prior to the addition
of Occidental as a partner on May 15, 1998, the Company had a 57.0 percent
joint venture ownership interest, while Millennium had 43.0 percent. Because
the Partners jointly control certain management decisions, Lyondell accounts
for its investment in Equistar using the equity method of accounting.

   As noted above, a direct subsidiary of the Company, Lyondell Petrochemical
G.P. Inc. ("General Partner") holds a 0.82% general partner interest in
Equistar.

   The General Partner has no independent operations of its own and certain of
its obligations as general partner have, under an agreement signed between the
Company and Equistar, been guaranteed by the Company. Accordingly, the audited
balance sheet of the Company, as guarantor of certain of the General Partner's
obligations, is presented at December 31, 1998. The General Partner had assets
consisting of its investment in Equistar of ($9) and invested capital, after
intercompany balances, of $9. The credit balance in the investment account is
due to the fact that the initial contribution of assets to Equistar was made by
Lyondell Petrochemical L.P. Inc. ("Limited Partner") and not allocated between
the General Partner and the Limited Partner. The investment account on the
General Partner's books reflects their proportionate share of income and
distributions from Equistar.

   Summarized financial information for Equistar is as follows as of December
31, 1998:

   At the formation of Equistar and adjusted for the addition of the Occidental
Contributed Business on May 15, 1998, the difference between the Company's
investment in Equistar and its underlying equity in Equistar's net assets was
approximately $900 million. This difference is being accreted into income of
the Company over 25 years using the straight-line method.

5. Equity Interest in LYONDELL-CITGO Refining LP

   In July 1993, LCR was formed to own and operate the Company's refining
business. LCR is structured as a Delaware limited partnership (formerly a Texas
limited liability company) owned by subsidiaries of the Company and CITGO. LCR
completed a major upgrade project at the Refinery ("Upgrade Project") during
the first quarter of 1997, which enabled the facility to process substantial
additional volumes of extra heavy crude oil. As a result of the completion of
the Upgrade Project, effective April 1, 1997, the participation interests
changed to reflect CITGO's equity contribution to the Upgrade Project. The
participation interests changed

from approximately 86 percent and 14 percent for the Company and CITGO,
respectively, and are currently 58.75 percent and 41.25 percent for the Company
and CITGO, respectively. Net income before depreciation expense for the period
is allocated to LCR's owners based upon participation interests. Depreciation
expense is allocated to the owners based upon contributed assets.

   Pursuant to contractual arrangements and concurrent with the completion of
the Upgrade Project, the authority and responsibility for certain management
decisions previously decided by majority vote, and therefore controlled by the
Company, changed to unanimous vote, resulting in joint control of LCR by
Lyondell and CITGO. Consequently, effective January 1, 1997, the Company began
to account for its investment in LCR using the equity method of accounting.

   Summarized financial information for LCR is as follows as of December 31,
1998. The results below include a restatement for a pricing adjustment between
LCR and Lyondell recorded in 1996 and retroactive to 1993.

   LCR has a long-term crude supply agreement ("Crude Supply Agreement") with
Lagoven, S.A., now known as PDVSA Petroleo y Gas, S.A. ("PDVSA Oil"), an
affiliate of CITGO. Under the Crude Supply Agreement, LCR is required to
purchase, and PDVSA Oil is required to sell, up to 230,000 barrels per day of
extra heavy Venezuelan crude oil. PDVSA Oil has the right, but not the
obligation, to supply incremental amounts above 230,000 barrels per day. The
Crude Supply Agreement incorporates formula prices to be paid by LCR for the
crude oil supplied based on the market value of a slate of refined products
deemed to be produced from each particular crude oil or feedstock, less: (i)
certain deemed refining costs, adjustable for inflation and energy costs; (ii)
certain actual costs; and (iii) a deemed margin, which varies according to the
grade of crude oil or other feedstock delivered. Deemed margins and deemed
costs are adjusted periodically. These adjustments are based upon inflation
rates and energy costs, however, deemed margin adjustments can be less than the
rate of inflation. Because deemed operating costs and the slate of refined
products deemed to be produced for a given barrel of crude oil or other
feedstock do not necessarily reflect the actual costs and yields in any period
and also because the market value of the refined products used in the pricing
formula does not necessarily reflect the actual price received for the refined
products, the actual refining margin earned by LCR under the Crude Supply
Agreement will vary depending upon, among other things, the efficiency with
which LCR conducts its operations during such period.

   Despite the limitations discussed above, the Crude Supply Agreement reduces
the volatility of earnings and cash flow of the refining operations of LCR
irrespective of market fluctuations of either crude oil or refined products.
Specifically, if the market value of refined products deemed to be produced
from the Venezuelan crude oil increases, the deemed cost of crude oil to LCR
will also increase. Alternatively, if the market value of refined products
deemed to be produced from the Venezuelan crude oil decreases, the deemed cost
of crude oil

to LCR will also decrease. This results in relatively stable deemed margins,
regardless of refined products market volatility. If the actual yields, costs
or volumes, differ substantially from those contemplated by the Crude Supply
Agreement, the benefits of this agreement to LCR could be substantially
different than anticipated.

   In addition, under the terms of a long-term product sales agreement
("Products Agreement"), CITGO purchases substantially all of the refined
products produced at the Refinery. Both PDVSA Oil and CITGO are direct or
indirect, wholly-owned subsidiaries of Petroleos de Venezuela, S.A., the
national oil company of the Republic of Venezuela.

   Under the terms of the Limited Partnership Agreement of LYONDELL-CITGO
Refining LP, CITGO has a one-time option to increase its participation interest
in LCR up to 50 percent by making an additional equity contribution after
January 1, 2000, but not later than September 30, 2000.

6. Equity Interest in Lyondell Methanol Company, L.P.

   Lyondell Methanol was formed in December 1996 by the Company and MCN
Investment Corporation ("MCNIC") to own and operate the methanol facility at
the Company's Channelview, Texas facility. At formation, the Company sold an
undivided 25 percent interest in the facility to MCNIC, creating Lyondell
Methanol, a Texas limited partnership owned by subsidiaries of the Company and
MCNIC. The Company owns the remaining 75 percent interest and serves as
managing partner. Since December 1, 1997, Equistar has served as operator of
the methanol facility. Lyondell Methanol sells all of its products to Equistar.

   In accordance with the guidance in Emerging Issues Task Force Issue No. 96-
16 issued in May 1997, the Company began to account for its investment in
Lyondell Methanol using the equity method of accounting, effective January 1,
1998.

7. Income Taxes

   Deferred income taxes reflect the net tax effects of temporary differences
between the carrying amounts of assets and liabilities for financial reporting
purposes, and the amounts used for income tax purposes. Significant components
of the Company's deferred tax liabilities and assets were as follows as of
December 31, 1998:

</TABLE>

   At December 31, 1998, net deferred tax assets of $76 million were classified
as "Deferred charges and other assets" on the Consolidated Balance Sheet.

   Under Internal Revenue Code Sections 338 (g) and (h) (10), Lyondell and ARCO
agreed to elect to step up the U.S. tax basis of the Acquired Company's net
assets. This will result in significantly increased depreciation and
amortization deductions for U.S. tax purposes.

8. Accounts Receivable

   In December 1998, the Company entered into a three-year receivables purchase
agreement with an independent issuer of receivables-backed commercial paper.
Under the terms of the agreement, the Company agreed to sell on an ongoing
basis and without recourse, designated accounts receivable. To maintain the
balance of the accounts receivable sold, the Company is obligated to sell new
receivables as existing receivables are collected. The agreement permits the
sale of up to $175 million of accounts receivable through December 2001.

   At December 31, 1998, the Company's gross accounts receivable that had been
sold to the purchasers aggregated $160 million.

9. Inventories

   Inventories are stated at the lower of cost or market. In 1998,
approximately 94 percent of inventories, excluding materials and supplies, were
determined by the last-in, first-out ("LIFO") method. Materials and supplies
and other non-LIFO inventories are valued using either the first-in, first-out
("FIFO") or the average cost methods. The excess of stated LIFO value over
current cost at December 31, 1998 is $136 million. However, stated LIFO value
does not exceed the net realizable value at December 31, 1998.

</TABLE>

   The above table for pension benefits includes foreign pension plans of ARCO
Chemical. These plans constituted approximately 20 percent of the benefit
obligation and 23 percent of the plan assets at December 31, 1998. The
assumptions used in determining the net periodic pension cost and pension
obligation for foreign pension plans were based on the economic environment of
each applicable country.

   The benefit obligation and accumulated benefit obligation for pension plans
with accumulated benefit obligations in excess of plan assets were $19 million
and $11 million, respectively, as of December 31, 1998. These plans are not
funded and consisted primarily of supplementary benefit plans for executives
and expatriates.

   In connection with the formation of Equistar, pension obligations and assets
were not contributed by Lyondell to Equistar. The employees transferred to
Equistar became fully vested in the Lyondell pension plan effective December 1,
1997 and no longer accrue pension service with Lyondell. However, an accrued

   For measurement purposes, the assumed annual rate of increase in the per
capita cost of covered health care benefits as of December 31, 1998 was 7.0
percent for 1999-2001 and 5.0 percent thereafter. A one-percentage-point
increase in assumed health care cost trend rates would increase the
postretirement benefit obligation by $10 million, while a one-percentage-point
decrease would reduce the obligation by $8 million. The effect of a one-
percentage-point change would be less than $1 million on the total of the
service and interest cost components.

14. Long-Term Debt and Financing Arrangements

   In connection with its purchase of the Acquired Business, the Company
executed a bank credit agreement providing for aggregate borrowings of up to
$7.0 billion ("Credit Facility"). As part of the acquisition, the Company
assumed approximately $870 million of ARCO Chemical debt. Borrowings under the
Credit Facility of $6.5 billion were used for: (i) the purchase of
approximately 97.4 million shares of ARCO Chemical common stock; (ii) repayment
of debt, including the $345 million term note payable to Equistar, short-term
borrowings of Lyondell and ARCO Chemical and other long-term borrowings of ARCO
Chemical; and (iii) payment of certain debt issuance costs.

   The Credit Facility comprises: (i) a five-year revolving credit facility of
up to $500 million to be used for general corporate purposes ("Revolving Credit
Facility"); and (ii) four separate term loans ("Term Loans") in the amounts of:
(a) $2.0 billion ("Term Loan A") to be amortized over five years; (b) $1.25
billion ("Term Loan B") to be amortized over seven years; (c) $1.25 billion
with principal maturing on June 30, 1999 ("Term Loan C"); and (d) $2.0 billion
with principal maturing on June 30, 2000 ("Term Loan D"). All of the Term Loans
were funded on July 28, 1998. No amounts have been funded to date under the
Revolving Credit Facility. The Credit Facility is collateralized by cash flow
streams from the Company's three joint ventures and the Company's common stock
ownership in its subsidiaries.

   The Term Loans bear interest at the following rates: (i) Term Loan A--LIBOR
plus 2.0 percent; (ii) Term Loan B--LIBOR plus 2.5 percent; (iii) Term Loan C--
LIBOR plus 2.0 percent; and (iv) Term Loan D--LIBOR plus 2.0 percent.

   Mandatory prepayments from certain sources of funds are required with
respect to the Term Loans until such time as: (i) Term Loans C and D are repaid
in full, including accrued interest and fees thereon; and (ii) Lyondell has
achieved investment grade ratings of at least BBB- and Baa3 from Standard &
Poor's Ratings Services and Moody's Investors Service, Inc., respectively. The
sources of funds for mandatory prepayments include: (i) cash proceeds received
from or as a result of: (a) certain equity or debt issuances; (b) the
recapitalization of LCR; and (c) asset sales, as defined; and (ii) 50 percent
of annual excess cash flow, as defined, less the aggregate principal amount
prepaid under the Term Loans.

               NOTES TO CONSOLIDATED BALANCE SHEET--(Continued)

   Under the covenant provisions of the Credit Facility, the Company has
agreed to, among other things: (i) maintain certain specified financial ratios
and consolidated net worth (as defined in the Credit Facility); (ii) refrain
from making certain distributions with respect to Lyondell's common stock;
(iii) refrain from making certain investments, as defined; (iv) refrain from
allowing its subsidiaries to incur certain types and amounts of debt; and (v)
use its best efforts to maintain certain ownership interests in its joint
ventures and to ensure that the joint ventures maintain certain capital
expenditure, debt level and cash distribution policies. The Credit Facility
requires the Company, among other things, to issue $1.25 billion of equity, as
defined, by July 23, 1999. The breach of any of the covenants or financial
requirements in the Credit Facility could result in a default thereunder,
which would permit the lenders to declare the loans immediately payable and to
terminate future lending commitments. The Company intends to seek an amendment
to the Credit Facility that would, among other things, substantially reduce
the requirements for the sale of equity and ease the financial ratio
requirements. The amendment requires approval by lenders holding a majority of
the commitments. Subject to the foregoing, the Company intends to complete an
amendment of the Credit Facility and to effect debt and equity offerings in
the second quarter of 1999, using the proceeds to meet the June 1999 debt
maturity. In addition, the Company is actively exploring alternative means of
retiring or refinancing debt, including other financing sources, enhancement
of operating cash flows through cost reductions, management of working capital
levels and sales of assets. Accordingly, the Company believes that it will be
able to satisfy its obligations through the actions discussed above.

   Long-term debt at December 31, 1998 consisted of the following:

   Lyondell transferred $744 million of long-term debt to Equistar on December
1, 1997 of which $713 million was outstanding at December 31, 1998. Lyondell
remains an obligor on the debt. Under certain limited circumstances the debt
holders have the right to require repurchase of up to $313 million of the
debt.

   Aggregate maturities of all long-term debt during the next five years are
$1.6 billion in 1999, $2.6 billion in 2000, $445 million in 2001, $445 million
in 2002, $446 million in 2003, and $1.4 billion thereafter.

15. Financial Instruments

   The Company does not buy or sell, or hold or issue financial instruments
for speculative trading purposes.

   Foreign currency swap and forward contracts are used to minimize foreign
exchange exposures. Foreign exchange exposures result from cash flows between
U.S. and international operations and transactions denominated in currencies
other than the local currency of an operating entity. Swap contracts and
forward

contracts are used to hedge foreign exchange exposures The notional amounts of
foreign currency contracts outstanding, principally involving the Netherlands
guilder, were $205 million at December 31, 1998 with various maturity dates in
1999.

  During 1998, to mitigate interest rate exposure on its anticipated future
public debt issuance, the Company entered into treasury-rate lock transactions
("Treasury Locks") in the notional amount of $1 billion. The Treasury Locks,
which are based on U.S. Treasury rates have an average interest rate of 5.52
percent with a determination date of August 5, 1999. The Company's accounting
policy is to defer any gains and losses on the Treasury Locks, and recognize
them as an adjustment to interest expense over the term of the debt issued.
The fair value of the Treasury Locks at December 31, 1998 was an obligation of
approximately $53 million, resulting from a decline in the relevant U.S.
Treasury rates. Had the Company issued the anticipated fixed-rate debt as of
December 31, 1998, it would have benefited from a lower interest rate on the
debt issued, resulting in lower interest expense over the life of the debt,
that would have been an offset to the potential settlement of the Treasury
Locks.

   The carrying value and the estimated fair value of the Company's financial
instruments as of December 31, 1998 are shown as assets (liabilities) in the
table below.

   All derivative instruments are off-balance-sheet instruments, however net
receivable or payable positions related to derivative instruments are carried
on the balance sheet.

   The fair value of all nonderivative financial instruments included in
current assets and current liabilities, including cash and cash equivalents,
accounts receivable, accounts payable and notes payable, approximated their
carrying value due to their short maturity. Investments and long-term
receivables, which consist primarily of equity investments in affiliated
companies, were valued using current financial and other available
information. Based upon the borrowing rates currently available to the Company
for debt with terms and average maturities similar to the Company's debt
portfolio, the fair value of the Company's long-term debt, including amounts
due within one year, was $7.0 billion at December 31, 1998. The fair value of
derivative financial instruments represents the amount to be exchanged if the
existing contracts were settled at December 31, 1998 and are based on market
quotes.

   The Company is exposed to credit risk related to its financial instruments
in the event of nonperformance by the counterparties. The Company does not
generally require collateral or other security to support these financial
instruments. The counterparties to these transactions are major institutions
deemed creditworthy by the Company. The Company does not anticipate
nonperformance by the counterparties.

16. Commitments and Contingencies

   The Company has commitments, including those related to capital
expenditures, all made in the normal course of business. During August 1998,
as contemplated at the time of the Acquisition, Lyondell announced the delay
of construction of a PO plant, known as PO-11, that ARCO Chemical had
previously scheduled for

                                     F-101
<PAGE>

                           LYONDELL CHEMICAL COMPANY

                NOTES TO CONSOLIDATED BALANCE SHEET--(Continued)

startup in late 2001. As part of the delay, the Company is negotiating the
cancellation of the related lump-sum contract for the engineering, procurement
and construction of the PO-11 plant. The Company recorded estimated liabilities
for penalties and cancellation charges related to the cancellation of the lump-
sum contract and related commitments at the time of the acquisition of ARCO
Chemical (see Note 3).

   The Acquired Business is party to a long-term supply arrangement for toluene
diisocyanate ("TDI"). Under the arrangement, the Company is entitled to all of
the TDI output of the supplier's two plants in France, which have a combined
rated capacity of approximately 264 million pounds per year. The Company is
required to purchase a minimum of 216 million pounds of TDI per year for up to
15 years, beginning January 1, 1995. The aggregate purchase price is a
combination of plant cost and market price. The Company is further obligated to
pay additional capacity reservation fees based upon plant output factors.

   Crude Supply Agreement--Depending upon market conditions, breach or
termination of LCR's Crude Supply Agreement could adversely affect LCR, and
therefore, the Company. Although the parties have negotiated alternate
arrangements in the event of a force majeure, which may arise from, among other
things, governmental or other actions restricting or otherwise limiting PDVSA
Oil's ability to perform its obligations, any such alternative arrangements may
not be as beneficial as the Crude Supply Agreement. There can be no assurance
that alternative crude oils with similar margins would be available for
purchase by LCR. Furthermore, the breach or termination of the Crude Supply
Agreement would require LCR to return to the practice of purchasing all or a
portion of its crude oil feedstocks in the merchant market and would again
subject LCR to significant volatility and price fluctuations. In late April
1998, LCR received notification from PDVSA Oil of reduced delivery of crude oil
related to announced OPEC production cuts. LCR began receiving the reduced
allocation of crude oil from PDVSA Oil in August 1998.

   Cross Indemnity Agreement--In connection with the transfer of assets and
liabilities from ARCO to the Company in 1988, the Company agreed to assume
certain liabilities arising out of the operation of the Company's integrated
petrochemicals and refining business prior to July 1, 1988. In connection with
the transfer of such liabilities, the Company and ARCO entered into an
agreement, updated in 1997 ("Revised Cross-Indemnity Agreement"), whereby the
Company agreed to defend and indemnify ARCO against certain uninsured claims
and liabilities which ARCO may incur relating to the operation of the business
of the Company prior to July 1, 1988, including certain liabilities which may
arise out of pending and future lawsuits. For current and future cases related
to Company products and Company operations, ARCO and the Company bear a
proportionate share of judgment and settlement costs according to a formula
that allocates responsibility based upon years of ownership during the relevant
time period. The party with the more significant potential liability exposure
is responsible for case management and associated costs while allowing the non-
case managing party to protect its interests. Under the Revised Cross-Indemnity
Agreement, the Company will assume responsibility for its proportionate share
of future costs for waste site matters not covered by ARCO insurance. Subject
to the uncertainty inherent in all litigation, management believes the
resolution of the matters pursuant to the Revised Cross-Indemnity Agreement
will not have a material adverse effect upon the Consolidated Financial
Statements of the Company.

   In connection with the Acquisition, the Company succeeded, indirectly, to a
cross indemnity agreement with ARCO whereby ARCO Chemical indemnified ARCO
against certain claims or liabilities that ARCO may incur relating to ARCO's
former ownership and operation of the businesses of ARCO Chemical ("Former ARCO
Businesses"), including liabilities under laws relating to the protection of
the environment and the workplace, and liabilities arising out of certain
litigation. As part of the agreement, ARCO indemnified ARCO Chemical with
respect to claims or liabilities and other matters of litigation not related to
the Former ARCO Businesses. ARCO also indemnified ARCO Chemical for certain
federal, foreign, state, and local taxes that might be assessed upon audit of
the operations of the Former ARCO Businesses for periods prior to July 1, 1987.

                           LYONDELL CHEMICAL COMPANY

                NOTES TO CONSOLIDATED BALANCE SHEET--(Continued)


   Indemnification Arrangements Relating to Equistar--Lyondell, Millennium and
Occidental have each agreed to provide certain indemnifications to Equistar
with respect to the petrochemicals and polymers businesses contributed by the
Partners. In addition, Equistar agreed to assume third party claims that are
related to certain pre-closing contingent liabilities asserted prior to
December 1, 2004 for Lyondell and Millennium, and May 15, 2005 for Occidental,
to the extent the aggregate thereof does not exceed $7 million to each Partner,
subject to certain terms of the respective Asset Contribution Agreements.
During the thirteen months ended December 31, 1998, approximately $1 million
had been expensed by Equistar under the $7 million indemnification basket with
respect to the business contributed by Lyondell.

   Environmental--The Company's policy is to be in compliance with all
applicable environmental laws. The Company is subject to extensive
environmental laws and regulations concerning emissions to the air, discharges
to surface and subsurface waters and the generation, handling, storage,
transportation, treatment and disposal of waste materials. Some of these laws
and regulations are subject to varying and conflicting interpretations. In
addition, the Company cannot accurately predict future developments, such as
increasingly strict environmental laws and inspection and enforcement policies,
as well as higher compliance costs arising therefrom, which might affect the
handling, manufacture, use, emission or disposal of products, other materials
or hazardous and non-hazardous waste.

   Pursuant to the terms of the Revised Cross-Indemnity Agreement, the Company
is currently contributing funds to the clean up of one waste site (Brio,
located near Houston, Texas) under the Comprehensive Environmental Response,
Compensation and Liability Act ("CERCLA") as amended and the Superfund
Amendments and Reauthorization Act of 1986. The Company is also subject to
certain assessment and remedial actions at the Refinery under the Resource
Conservation and Recovery Act ("RCRA"). In addition, the Company has negotiated
an order with the Texas Natural Resource Conservation Commission ("TNRCC") for
assessment and remediation of groundwater and soil contamination at the
Refinery.

   As of December 31, 1998, the Company has accrued $9 million related to
future CERCLA, RCRA and TNRCC assessment and remediation costs associated with
the above mentioned sites. The costs are expected to be incurred over the next
two to seven years. In the opinion of management, there is currently no
material range of loss in excess of the amount recorded for these sites.
However, it is possible that new information about the sites for which the
reserve has been established, new technology or future developments such as
involvement in other CERCLA, RCRA, TNRCC or other comparable state law
investigations, could require the Company to reassess its potential exposure
related to environmental matters.

   As part of the Acquisition (see Note 3), the Company assumed ARCO Chemical's
environmental liability, which totaled $39 million at December 31, 1998 and
reflects the Company's latest assessment of potential future remediation costs
associated with known ARCO Chemical sites. The liability is related to four
current plant sites, one former plant site and one federal Superfund site for
amounts ranging from $2 million to $18 million per site. Further, the Acquired
Business is involved in administrative proceedings or lawsuits relating to a
minimal number of other Superfund sites. The Company estimates however, based
upon currently available information, that potential loss contingencies
associated with these sites, individually and in the aggregate, are not
significant. Substantially all amounts accrued are expected to be paid out over
the next five to ten years.

   The Company has relied upon remedial investigation/feasibility studies
("RI/FS") at each site of the Acquired Business as a basis for estimating
remediation costs at the site. RI/FS or preliminary assessments have been
completed at most of the sites. However, selection of the remediation method
and the cleanup standard to be applied are, in most cases, subject to approval
by the appropriate government authority. Accordingly, the Company may have
possible loss contingencies in excess of the amounts accrued to the extent the
scope of remediation required, the final remediation method selected and/or the
cleanup standard applied,

                                     F-103
<PAGE>

                           LYONDELL CHEMICAL COMPANY

                NOTES TO CONSOLIDATED BALANCE SHEET--(Continued)

vary from the assumptions used in estimating the liability. The Company
estimates that the upper range of these possible loss contingencies should not
exceed the amount accrued by more than $65 million.

   During July 1994, the Company reported results of an independent
investigation conducted by the Audit Committee of the Board of Directors
regarding the compliance status of two process waste-water streams under the
applicable Benzene National Emissions Standard for Hazardous Air Pollutants
("NESHAPS") regulations and certain issues raised by an employee. The Company
has been informed that this matter is considered closed by the EPA and no
further enforcement action is anticipated.

   The extent of loss related to environmental matters ultimately depends upon
a number of factors, including technological developments, changes in
environmental laws, the number and ability to pay of other parties involved at
a particular site and the Company's potential involvement in additional
environmental assessments and cleanups. Based upon currently known facts,
management believes that any remediation costs the Company may incur in excess
of the amounts accrued or disclosed above would not have a material adverse
impact on the Company's Consolidated Financial Statements.

   MTBE--Certain federal and state legislative initiatives have sought to
either rescind the oxygenate requirement for reformulated gasoline sold in
California and other states or restrict the use of MTBE. There is ongoing
review of this issue and the ultimate resolution of the appropriateness of
using MTBE could result in a significant reduction in the Company's MTBE sales.
In addition, the Company has a take-or-pay contract with ARCO, which
contributes significant pretax margin. If such legislative initiatives were
enacted, ARCO has indicated that it might attempt to invoke a force majeure
provision in the contract in order to reduce the quantities of MTBE it
purchases under, or to terminate, the contract. The Company would vigorously
dispute such action.

   General--The Company is involved in various lawsuits and proceedings.
Subject to the uncertainty inherent in all litigation, management believes the
resolution of these proceedings will not have a material adverse effect upon
the Consolidated Financial Statements of the Company.

   In the opinion of management, any liability arising from the matters
discussed in this Note is not expected to have a material adverse effect on the
Consolidated Financial Statements of the Company. However, the adverse
resolution in any reporting period of one or more of these matters discussed in
this Note could have a material impact on the Company's results of operations
for that period without giving effect to contribution or indemnification
obligations of co-defendants or others, or to the effect of any insurance
coverage that may be available to offset the effects of any such award.

17. Lease Commitments

   The Company leases various facilities and equipment under noncancelable
lease arrangements for varying periods. As of December 31, 1998, future minimum
lease payments for years ending December 31, relating to all noncancelable
operating leases with lease terms in excess of one year were as follows:

18. Stockholders' Equity

   Treasury Stock--From time to time the Company purchases its shares in the
open market to be used for issuances under the Company's employee compensation
and benefits plans, including stock option and restricted stock plans. During
1998, the Company purchased 500,000 shares for approximately $10 million to be
used for such plans. The Company reissued, under the Restricted Stock Plan,
88,848 shares previously purchased. Earlier in 1998, the Company completed the
stock repurchase program authorized by the Company's Board of Directors in
September 1997. A total of 2,567,051 shares were purchased for $75 million
under this stock repurchase program.

   Restricted Stock Plan--During 1998 the Company granted and issued 88,848
shares of restricted stock to employees of the Acquired Business. The shares
vest on various dates through December 15, 2000, depending upon the terms of
the individual grants. Employees are entitled to receive dividends on the
restricted shares.

   Rights to Purchase Common Stock--On December 8, 1995, the Board of Directors
of Lyondell declared a dividend of one right ("Right") for each outstanding
share of the Company's common stock to stockholders of record on December 20,
1995. The Rights become exercisable upon the earlier of: (i) ten days following
a public announcement by another entity that it has acquired beneficial
ownership of 15 percent or more of the outstanding shares of common stock; or
(ii) ten business days following the commencement of a tender offer or exchange
offer to acquire beneficial ownership of 15 percent or more of the outstanding
shares of common stock, except under certain circumstances. The Rights expire
at the close of business on December 8, 2005 unless earlier redeemed at a price
of $.0005 per Right or exchanged by the Company as described in the Rights
Agreement dated as of December 8, 1995.

   Preferred Stock--The Company has authorized 80,000,000 shares of preferred
stock, $.01 par value, of which none were issued or outstanding at December 31,
1998.

   Stock Options--The Company's Executive Long-Term Incentive Plan ("LTI Plan")
became effective in November 1988. The last stock options granted under the LTI
Plan were granted in March 1994. No additional stock option grants will be made
under this plan. The LTI Plan provided, among other compensation awards, for
the granting to officers and other key management employees of non-qualified
stock options for the purchase of up to 1,295,000 shares of the Company's
common stock. The number of options exercisable each year is equal to 25
percent of the number granted after each year of continuous service starting
one year from the date of grant. The LTI Plan provided that the option price
per share was not less than 100 percent of the fair market value of the stock
on the effective date of the grant. As of December 31, 1998, options covering
621,835 shares were outstanding under the LTI Plan with a weighted average
remaining life of 4 years, all of which were exercisable at prices ranging from
$18.25 to $30.00 per share.

   The Company's Incentive Stock Option Plan ("ISO Plan"), a tax qualified
plan, became effective in January 1989. The last stock options granted under
the ISO Plan were granted in March 1993. No additional grants will be made
under the ISO Plan. All employees of the Company who were not on the executive
payroll were eligible to participate in the ISO Plan, subject to certain
restrictions. Various restrictions apply as to when and to the number of stock
options that may be exercised during any year. As of December 31, 1998, options
covering 145,191 shares were outstanding at $30.00 per share. These options
were held by 641 eligible employees and expired in January 1999. At December
31, 1998, no stock options were exercisable.

   Employee stock options are accounted for under the intrinsic value based
method prescribed by the Accounting Principles Board Opinion No. 25, Accounting
for Stock Issued to Employees. Accordingly, no compensation cost has been
recognized in connection with stock option grants under the plans. There were
no grants in any of the years ended December 31, 1998.

NOTE 1--BASIS OF PRESENTATION AND DESCRIPTION OF COMPANY

   Millennium Chemicals Inc. (the "Company") is a major international chemicals
company, with leading market positions in a broad range of commodity,
industrial, performance and specialty chemicals, operating through its
subsidiaries: Millennium Inorganic Chemicals Inc. (and its non-United States
affiliates), Millennium Petrochemicals Inc., and Millennium Specialty Chemicals
Inc.; and, beginning December 1, 1997, through its interest in Equistar
Chemicals, LP ("Equistar"), a joint venture formed by the Company and Lyondell
Chemical Company ("Lyondell") to jointly own and operate the petrochemical and
polymer businesses of the Company and Lyondell. On May 15, 1998, the Company's
interest in Equistar was reduced to 29.5% with the addition of the ethylene,
propylene, ethylene oxide, ethylene glycol and other ethylene oxide derivatives
businesses of Occidental Petroleum Corporation's ("Occidental") chemical
subsidiary. The balance sheet of the Company at June 30, 1999 and notes thereto
is presented because the Company guarantees to Equistar certain obligations of
the Company's indirect subsidiary that serves as a general partner of Equistar
(see Note 2).

   The Company was incorporated on April 18, 1996, and has been publicly owned
since October 1, 1996, when Hanson PLC ("Hanson") transferred its chemical
operations to the Company and, in consideration, all of the then outstanding
shares of the Company's common stock ("Common Stock") were distributed pro rata
to Hanson's shareholders (the "Demerger").

   The accompanying unaudited consolidated balance sheet has been prepared in
accordance with the rules and regulations of the Securities and Exchange
Commission. In the opinion of management, the consolidated balance sheet
includes all adjustments necessary for a fair statement of the financial
position for the period presented in conformity with generally accepted
accounting principles. Such adjustments consist only of normal recurring items.
All significant intercompany accounts and transactions have been eliminated.

NOTE 2--ACQUISITIONS AND DISPOSITIONS

   On December 1, 1997, the Company and Lyondell completed the formation of
Equistar, a joint venture partnership created to own and operate the
petrochemical and polymer businesses of the Company and Lyondell. The Company
contributed to Equistar substantially all of the net assets of its
polyethylene, performance polymer and ethyl alcohol businesses. The Company
retained $250 from the proceeds of accounts receivable collections and
substantially all the accounts payable and accrued expenses of its contributed
businesses existing on December 1, 1997, and received proceeds of $750 from
borrowings under a new credit facility entered into by Equistar. The Company
used the $750 which it received to repay debt. A subsidiary of the Company
guarantees $750 of Equistar's credit facility.

   Equistar was owned 57% by Lyondell and 43% by the Company until May 15,
1998, when the Company and Lyondell expanded Equistar with the addition of the
ethylene, propylene, ethylene oxide, ethylene glycol and other ethylene oxide
derivatives businesses of Occidental's chemical subsidiary. Occidental
contributed the net assets of those businesses (including approximately $205 of
related debt) to Equistar. In exchange, Equistar borrowed an additional $500,
$420 of which was distributed to Occidental and $75 to the Company. Equistar is
now owned 41% by Lyondell, 29.5% by Occidental and 29.5% by the Company. No
gain or loss resulted from this transaction.

   Equistar is managed by a Partnership Governance Committee consisting of
representatives of each partner. Approval of Equistar's strategic plans and
other major decisions requires the consent of the representatives of the three
partners. All decisions of Equistar's Governance Committee that do not require
unanimity among the partners may be made by Lyondell's representatives alone.

          NOTES TO CONSOLIDATED BALANCE SHEET (Unaudited)--(Continued)
                    (dollars in millions, except share data)


   An indirect subsidiary of the Company, Millennium Petrochemicals GP LLC
("General Partner") holds a .59% general partner interest in Equistar.

   The General Partner has no independent operations of its own and certain of
its performance obligations as general partner have, under an agreement signed
between the Company and Equistar, been guaranteed by the Company. Accordingly,
the balance sheet of the Company, as guarantor of certain of the General
Partner's obligations, is presented at June 30, 1999. The General Partner had
assets consisting of its investment in Equistar of $32 and invested capital,
after intercompany balances, of $32.

   The investment in Equistar at the date of contribution represented the
carrying value of the Company's contributed net assets, less cash received, and
approximated the fair market value of its interest in Equistar based upon
independent valuation. The difference between the carrying value of the
Company's investment and its underlying equity in the net assets of Equistar
has been reduced from $617 to $404 as a result of adding Occidental as a
partner and is being amortized over 25 years. The Company accounts for its
interest in Equistar using the equity method.

   On July 1, 1998, the Company completed the acquisition of 99% of the voting
shares and 72% of total shares of Titanio do Brazil S.A. ("Tibras"), Brazil's
only integrated TiO2 producer, for $129, including assumed debt. This
acquisition was accounted for using the purchase method of accounting with the
purchase price allocated to the net assets acquired, principally property,
plant and equipment and working capital based on their fair value. The two
operations comprising Tibras included a plant which has capacity to produce
approximately 60 thousand metric tons per year of TiO2 and a mineral sands mine
with over 2 million metric tons of recoverable reserves.

   On January 18, 1999, the Company completed transactions with Linde AG
("Linde") relating to the Company's synthesis gas ("syngas") unit in La Porte,
Texas, and a 15% interest in its methanol business, whereby the Company
received $122.5 in cash. Linde operates the syngas facility under a long-term
lease with a purchase option. In addition, Linde operates and holds a 15%
interest in the methanol facility. No gain or loss resulted from these
transactions.

   In March 1996, the Company sold a 73.6% interest in Suburban Propane,
through an initial public offering of 21,562,500 common units in a new master
limited partnership, Suburban Propane Partners, L.P., and received aggregate
proceeds from the sale of the common units and the issuance of notes of the
Suburban Propane operating partnership, Suburban Propane, L.P., of
approximately $831. The Company retained a combined subordinated and general
partnership interest of 26.4% in Suburban Propane Partners, L.P. and Suburban
Propane, L.P. (collectively "Suburban Propane"). On May 26, 1999, the Company
sold its remaining interest to Suburban Propane and its management for $75 in
cash, resulting in an after-tax gain of $31.

NOTE 3--SIGNIFICANT ACCOUNTING POLICIES

   Use of Estimates: The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities at
the date of the financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates.

   Inventories: Inventories are stated at the lower of cost or market value.
For certain United States operations, cost is determined under the last-in,
first-out (LIFO) method. The first-in, first-out (FIFO) method, or methods
which approximate FIFO, are used by all other subsidiaries.

</TABLE>

   Inventories valued on a LIFO basis were approximately $40 less than the
amount of such inventories valued at current cost at June 30, 1999.

   Property, Plant and Equipment: Property, plant and equipment is stated on
the basis of cost. Depreciation is provided by the straight-line method over
the estimated useful lives of the assets, generally 20 to 40 years for
buildings and 5 to 25 years for machinery and equipment.

   Goodwill: Goodwill represents the excess of the purchase price over the fair
value of assets allocated to acquired companies. Goodwill is being amortized
using the straight-line method over 40 years. Management periodically evaluates
goodwill for impairment based on the anticipated future cash flows attributable
to its operations. Such expected cash flows, on an undiscounted basis, are
compared to the carrying value of the tangible and intangible assets, and if
impairment is indicated, the carrying value of goodwill is adjusted. In the
opinion of management, no impairment of goodwill exists at June 30, 1999.

   Environmental Liabilities and Expenditures: Accruals for environmental
matters are recorded in operating expenses when it is probable that a liability
has been incurred and the amount of the liability can be reasonably estimated.
Accrued liabilities are exclusive of claims against third parties (except where
payment has been received or the amount of liability or contribution by such
other parties has been agreed) and are not discounted. In general, costs
related to environmental remediation are charged to expense. Environmental
costs are capitalized if the costs increase the value of the property and/or
mitigate or prevent contamination from future operations.

   Foreign Currency Translation: Assets and liabilities of the Company's
foreign operating subsidiaries are translated at the exchange rates in effect
at the balance sheet dates while revenues, expenses and cash flows are
translated at average exchange rates for the reporting period. Resulting
translation adjustments are recorded as a currency translation adjustment in
Shareholders' equity. Gains and losses resulting from foreign exchange changes
on transactions denominated in currencies other than the functional currency
are recognized in income except for gains and losses on hedges of net
investments which are included as a component of Shareholders' equity.

   Federal Income Taxes: Deferred tax assets and liabilities are computed based
on the difference between the financial statement basis and income tax basis of
assets and liabilities using enacted marginal tax rates of the respective tax
jurisdictions.

   The Company and certain of its subsidiaries have entered into tax-sharing
and indemnification agreements with Hanson or its subsidiaries in which the
Company and/or its subsidiaries generally agreed to indemnify

</TABLE>

   Under the Revolving Credit Agreement, as amended on October 20, 1997,
certain of the Company's subsidiaries may borrow up to $500 under an unsecured
multi-currency revolving credit facility, which matures in July 2001 (the
"Credit Agreement" or the "Revolving Credit Facility"). The Company is the
guarantor of this facility. Borrowings under the Credit Agreement may consist
of standby loans or uncommitted competitive loans offered by syndicated banks
through an auction bid procedure. Loans may be borrowed in U.S. dollars and/or
other currencies. The proceeds from the borrowings may be used to provide
working capital and for general corporate purposes.

   The Credit Agreement contains covenants and provisions that restrict, among
other things, the ability of the Company and its material subsidiaries to: (i)
create liens on any of its property or assets, or assign any rights to or
security interests in future revenues; (ii) engage in sale-and-leaseback
transactions; (iii) engage in mergers, consolidations or sales of all or
substantially all of their assets on a consolidated basis; (iv) enter into
agreements restricting dividends and advances by their subsidiaries; and (v)
engage in transactions with affiliates other than those based on arm's-length
negotiations. The Credit Agreement also limits the ability of certain
subsidiaries of the Company to incur indebtedness or issue preferred stock. In
addition, the Credit Agreement requires the Company to satisfy certain
financial performance criteria.

   The Senior Notes and Senior Debentures were issued by Millennium America
Inc., a wholly owned subsidiary of the Company, and are guaranteed by the
Company. The indenture under which the Senior Notes and Senior Debentures were
issued contains certain covenants that limit, among other things: (i) the
ability of Millennium America Inc. and its Restricted Subsidiaries (as defined)
to grant liens or enter into sale-and-leaseback transactions; (ii) the ability
of the Restricted Subsidiaries to incur additional indebtedness; and (iii) the
ability of Millennium America Inc. and the Company to merge, consolidate or
transfer substantially all of their respective assets.

NOTE 5--RELATED PARTY TRANSACTIONS

   One of the Company's subsidiaries purchases ethylene from Equistar at
market-related prices pursuant to an agreement made in connection with the
formation of Equistar. Under the agreement the subsidiary is required to
purchase 100% of its ethylene requirements for its La Porte, Texas, facility up
to a maximum of 330 million pounds per year. The initial term of the contract
expires December 1, 2000. Thereafter, the contract automatically renews
annually. Either party may terminate on one year's notice.

                    (dollars in millions, except share data)


NOTE 6--COMMITMENTS AND CONTINGENCIES

   The Company is subject, among other things, to several proceedings under the
Federal Comprehensive Environmental Response Compensation and Liability Act and
other federal and state statutes or agreements with third parties. These
proceedings are in various stages ranging from initial investigation to active
settlement negotiations to implementation of the clean-up or remediation of
sites. Additionally, certain of the Company's subsidiaries are defendants or
plaintiffs in lawsuits that have arisen in the normal course of business
including those relating to commercial transactions and product liability.
While certain of the lawsuits involve allegedly significant amounts, it is
management's opinion, based on the advice of counsel, that the ultimate
resolution of such litigation will not have a material adverse effect on the
Company's financial position or results of operations. The Company believes
that the range of potential liability for these matters, collectively, which
primarily relate to environmental remediation activities, is between $150 and
$169 and has accrued $169 as of June 30, 1999.

   The Company has various contractual obligations to purchase raw materials
used in its production of TiO2 and fragrance and flavor chemicals. Commitments
to purchase ore used in the production of TiO2 are generally 1-to 8-year
contracts with competitive prices generally determined at a fixed amount
subject to escalation for inflation. Total commitments to purchase ore for TiO2
aggregate approximately $1,100 and expire between 1999 and 2002. Commitments to
acquire crude sulfate turpentine, used in the production of fragrance
chemicals, are generally pursuant to 1-to 5-year contracts with prices based on
the market price and which expire between 1999 and 2008.

   The Company is organized under the laws of Delaware and is subject to United
States federal income taxation of corporations. However, in order to obtain
clearance from the United Kingdom Inland Revenue as to the tax-free treatment
of the Demerger stock dividend for United Kingdom tax purposes for Hanson and
Hanson's shareholders, Hanson agreed with the United Kingdom Inland Revenue
that the Company will continue to be centrally managed and controlled in the
United Kingdom at least until September 30, 2001. Hanson also agreed that the
Company's Board of Directors will be the only medium through which strategic
control and policy-making powers are exercised, and that board meetings almost
invariably will be held in the United Kingdom during this period. The Company
has agreed not to take, or fail to take, during such five-year period, any
action that would result in a breach of, or constitute non-compliance with, any
of the representations and undertakings made by Hanson in its agreement with
the United Kingdom Inland Revenue and to indemnify Hanson against any liability
and penalties arising out of a breach of such agreement. The Company's By-Laws
provide for similar constraints. The Company and Hanson estimate that such
indemnification obligation would have amounted to approximately $421 if it had
arisen during the twelve months ended September 30, 1997, and that such
obligation will decrease by approximately $84 on each October 1 prior to
October 1, 2001, when it will expire.

   If the Company ceases to be a United Kingdom tax resident at any time, the
Company will be deemed, for purposes of United Kingdom corporation tax on
chargeable gains, to have disposed of all of its assets at such time. In such a
case, the Company would be liable for United Kingdom corporation tax on
chargeable gains on the amount by which the fair market value of those assets
at the time of such deemed disposition exceeds the Company's tax basis in those
assets. The tax basis of the assets would be calculated in pounds sterling,
based on the fair market value of the assets (in pounds sterling) at the time
of acquisition of the assets by the Company, adjusted for United Kingdom
inflation. Accordingly, in such circumstances, the Company could incur a tax
liability even though it has not actually sold the assets and even though the
underlying value of the assets may not actually have appreciated (due to
currency movements). Since it is impossible to predict the future value of the
Company's assets, currency movements and inflation rates, it is impossible to
predict the magnitude of such liability, should it arise.

                    (dollars in millions, except share data)

NOTE 1--BASIS OF PRESENTATION AND DESCRIPTION OF COMPANY

   Millennium Chemicals Inc. (the "Company") is a major international chemicals
company, with leading market positions in a broad range of commodity,
industrial, performance and specialty chemicals, operating through its
subsidiaries: Millennium Inorganic Chemicals Inc. (and its non-United States
affiliates), Millennium Petrochemicals Inc., and Millennium Specialty Chemicals
Inc.; and, beginning December 1, 1997, through its interest in Equistar
Chemicals, L.P. ("Equistar"), a joint venture formed by the Company and
Lyondell Chemical Company ("Lyondell") to jointly own and operate the
petrochemical and polymer businesses of the Company and Lyondell. On May 15,
1998, the Company's interest in Equistar was reduced to 29.5% with the addition
of the ethylene, propylene, ethylene oxide and derivatives businesses of
Occidental Petroleum Corporation's ("Occidental") chemical subsidiary. The
balance sheet of the Company at December 31, 1998 and notes thereto is
presented because the Company guarantees to Equistar certain obligations of the
Company's indirect subsidiary that serves as a general partner of Equistar (see
Note 2).

   The Company was incorporated on April 18, 1996, and has been publicly owned
since October 1, 1996, when Hanson PLC ("Hanson") transferred its chemical
operations to the Company and, in consideration, all of the then outstanding
shares of the Company's common stock ("Common Stock") were distributed pro rata
to Hanson's shareholders.

   All significant intercompany accounts and transactions have been eliminated.

NOTE 2--ACQUISITIONS AND DISPOSITIONS

   On December 1, 1997, the Company and Lyondell completed the formation of
Equistar, a joint venture partnership created to own and operate the
petrochemical and polymer businesses of the Company and Lyondell. The Company
contributed to Equistar substantially all of the net assets of its
polyethylene, performance polymer and ethyl alcohol businesses. The Company
retained $250 from the proceeds of accounts receivable collections and
substantially all the accounts payable and accrued expenses of its contributed
businesses existing on December 1, 1997, and received proceeds of $750 from
borrowings under a new credit facility entered into by Equistar. The Company
used the $750 which it received to repay debt. A subsidiary of the Company
guarantees $750 of Equistar's credit facility.

   Equistar was owned 57% by Lyondell and 43% by the Company until May 15,
1998, when the Company and Lyondell expanded Equistar with the addition of the
ethylene, propylene, ethylene oxide and derivatives businesses of Occidental's
chemical subsidiary. Occidental contributed the net assets of those businesses
(including approximately $205 of related debt) to Equistar. In exchange,
Equistar borrowed an additional $500, $420 of which was distributed to
Occidental and $75 to the Company. Equistar is now owned 41% by Lyondell, 29.5%
by Occidental and 29.5% by the Company. No gain or loss resulted from this
transaction.

   Equistar is managed by a Partnership Governance Committee consisting of
representatives of each partner. Approval of Equistar's strategic plans and
other major decisions requires the consent of the representatives of the three
partners. All decisions of Equistar's Governance Committee that do not require
unanimity among the partners may be made by Lyondell's representatives alone.

   An indirect subsidiary of the Company, Millennium Petrochemicals GP LLC
("General Partner") holds a .59% general partner interest in Equistar.

   The General Partner has no independent operations of its own and certain of
its performance obligations as general partner have, under an agreement signed
between the Company and Equistar, been guaranteed by the Company. Accordingly,
the audited balance sheet of the Company, as guarantor of certain of the
General Partner's obligations, is presented at December 31, 1998. The General
Partner had assets consisting of its investment in Equistar of $32 and invested
capital, after intercompany balances, of $32.

                NOTES TO CONSOLIDATED BALANCE SHEET--(Continued)
                    (dollars in millions, except share data)


   The investment in Equistar at the date of contribution represented the
carrying value of the Company's contributed net assets, less cash received, and
approximated the fair market value of its interest in Equistar based upon
independent valuation. The difference between the carrying value of the
Company's investment and its underlying equity in the net assets of Equistar
has been reduced from $617 to $404 as a result of adding Occidental as a
partner and is being amortized over 25 years. The Company accounts for its
interest in Equistar using the equity method.

   On July 1, 1998, the Company completed the acquisition of 99% of the voting
shares and 72% of total shares of Titanio do Brazil S.a. ("Tibras"), Brazil's
only integrated TiO\\2\\ producer, for $129, including assumed debt. This
acquisition was also accounted for using the purchase method of accounting with
the purchase price allocated to the net assets acquired, principally property,
plant and equipment and working capital based on their fair value. The two
operations comprising Tibras included a plant which has capacity to produce
approximately 60 thousand metric tons per year of TiO\\2\\ and a mineral sands
mine with over 2 million metric tons of recoverable reserves.

   On November 16, 1998, the Company entered into agreements with Linde AG
("Linde") relating to the Company's synthesis gas ("syngas") unit in La Porte,
Texas, and a 15% interest in its methanol business, whereby the Company would
receive $122.5 in cash. Linde will operate the syngas facility under a long-
term lease with a purchase option. In addition, Linda will operate and hold a
15% interest in the methanol facility. As a result, the assets involved in this
transaction, including applicable goodwill of $42, have been classified at
December 31, 1998 in the accompanying balance sheet as Assets of discontinued
interests. This transaction was subsequently completed on January 18, 1999. No
gain or loss resulted from this transaction.

   In March 1996, the Company sold a 73.6% interest in Suburban Propane,
through an initial public offering of 21,562,500 common units in a new master
limited partnership, Suburban Propane Partners, L.P., and received aggregate
proceeds from the sale of the common units and the issuance of notes of the
Suburban Propane operating partnership, Suburban Propane, L.P., of
approximately $831. The Company retained a combined subordinated and general
partnership interest of 26.4% in Suburban Propane Partners L.P. and Suburban
Propane L.P. (collectively "Suburban Propane"). On November 27, 1998, the
Company entered into an agreement to sell its remaining interest to Suburban
Propane and its management for $75 in cash, with an expected net after-tax gain
of approximately $30. As such, Suburban Propane is reflected as a discontinued
operation and the Company's interest at December 31, 1998 is included in Assets
of discontinued interests.

NOTE 3--SIGNIFICANT ACCOUNTING POLICIES

   Use of Estimates: The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities at
the date of the financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates.

   Cash Equivalents: Cash equivalents represent investments in short-term
deposits and commercial paper with banks which have original maturities of 90
days or less. In addition, investments and other assets include approximately
$31 in restricted cash at December 31, 1998 which is on deposit to satisfy
insurance claims.

   Inventories: Inventories are stated at the lower of cost or market value.
For certain United States operations, cost is determined under the last-in,
first-out (LIFO) method. The first-in, first-out (FIFO) method, or methods
which approximate FIFO, are used by all other subsidiaries.

                NOTES TO CONSOLIDATED BALANCE SHEET--(Continued)
                    (dollars in millions, except share data)


   Property, Plant and Equipment: Property, plant and equipment is stated on
the basis of cost. Depreciation is provided by the straight-line method over
the estimated useful lives of the assets, generally 20 to 40 years for
buildings and 5 to 25 years for machinery and equipment.

   Goodwill: Goodwill represents the excess of the purchase price over the fair
value of assets allocated to acquired companies. Goodwill is being amortized
using the straight-line method over 40 years. Management periodically evaluates
goodwill for impairment based on the anticipated future cash flows attributable
to its operations. Such expected cash flows, on an undiscounted basis, are
compared to the carrying value of the tangible and intangible assets, and if
impairment is indicated, the carrying value of goodwill is adjusted. In the
opinion of management, no impairment of goodwill exists at December 31, 1998.

   Environmental Liabilities and Expenditures: Accruals for environmental
matters are recorded in operating expenses when it is probable that a liability
has been incurred and the amount of the liability can be reasonably estimated.
Accrued liabilities are exclusive of claims against third parties (except where
payment has been received or the amount of liability or contribution by such
other parties, including insurance companies, has been agreed) and are not
discounted. In general, costs related to environmental remediation are charged
to expense. Environmental costs are capitalized if the costs increase the value
of the property and/or mitigate or prevent contamination from future
operations.

   Foreign Currency Translation: Assets and liabilities of the Company's
foreign operating subsidiaries are translated at the exchange rates in effect
at the balance sheet dates, while revenue, expenses and cash flows are
translated at average exchange rates for the reporting period. Resulting
translation adjustments are recorded as a currency component of Shareholders'
equity. Gains and losses resulting from foreign exchange changes on
transactions denominated in currencies other than the functional currency are
recognized in income except for gains and losses on hedges of net investments
which are included as a component of Shareholders' equity.

   Federal Income Taxes: Deferred tax assets and liabilities are computed based
on the difference between the financial statement basis and income tax basis of
assets and liabilities using enacted marginal tax rates of the respective tax
jurisdictions.

   The Company and certain of its subsidiaries have entered into tax-sharing
and indemnification agreements with Hanson or its subsidiaries in which the
Company and/or its subsidiaries generally agreed to indemnify Hanson or its
subsidiaries for income tax liabilities attributable to periods when such other
operations were included in the consolidated tax returns of the Company's
subsidiaries.

   At December 31, 1998, certain foreign subsidiaries of the Company had
available net operating loss carryforwards aggregating $20, which are subject
to certain limitations on their use.

   Certain of the income tax returns of the Company's subsidiaries are
currently under examination by the Internal Revenue Service and various state
tax agencies. In the opinion of management, any assessments which may result
will not have a material adverse effect on the financial condition or results
of operations of the Company.

   Under the Revolving Credit Agreement, as amended on October 20, 1997,
certain of the Company's subsidiaries may borrow up to $500 under an unsecured
multi-currency revolving credit facility, which matures in July 2001 (the
"Credit Agreement" or the "Revolving Credit Facility"). The Company is the
guarantor of this facility. Borrowings under the Credit Agreement may consist
of standby loans or uncommitted competitive loans offered by syndicated banks
through an auction bid procedure. Loans may be borrowed in U.S. dollars and/or
other currencies. The proceeds from the borrowings may be used to provide
working capital and for general corporate purposes.

   The Credit Agreement contains covenants and provisions that restrict, among
other things, the ability of the Company and its material subsidiaries to: (i)
create liens on any of its property or assets, or assign any rights to or
security interests in future revenues; (ii) engage in sale-and-leaseback
transactions; (iii) engage in mergers, consolidations or sales of all or
substantially all of their assets on a consolidated basis; (iv) enter into
agreements restricting dividends and advances by their subsidiaries; and (v)
engage in transactions with affiliates other than those based on arm's-length
negotiations. The Credit Agreement also limits the ability of certain
subsidiaries of the Company to incur indebtedness or issue preferred stock. In
addition, the Credit Agreement requires the Company to satisfy certain
financial performance criteria.

   The Senior Notes and Senior Debentures were issued by Millennium America
Inc., a wholly owned subsidiary of the Company, and are guaranteed by the
Company. The indenture under which the Senior Notes and Senior Debentures were
issued contains certain covenants that limit, among other things; (i) the
ability of Millennium America Inc. and its Restricted Subsidiaries (as defined)
to grant liens or enter into sale-and-leaseback transactions; (ii) the ability
of the Restricted Subsidiaries to incur additional indebtedness; and (iii) the
ability of Millennium America Inc. and the Company to merge, consolidate or
transfer substantially all of their respective assets.

   At December 31, 1998, the Company had outstanding notes payable of $29
bearing interest at an average rate of approximately 12% with maturity of 30
days or less. At December 31, 1998, the Company had outstanding standby letters
of credit amounting to $102 and had unused availability under short-term lines
of credit and its Revolving Credit Facility of $432. In addition, Millennium
America Inc. has guaranteed certain debt obligations of Equistar up to $750.

   The maturities of long-term debt during the next five years are as follows:
1999--$5; 2000--$24; 2001--$245; 2002--$5; and 2003 and beyond--$760.

NOTE 7--FINANCIAL INSTRUMENTS

   Fair Value of Financial Instruments: The fair value of all short-term
financial instruments approximate their carrying value due to their short
maturity. The fair value of long-term financial instruments (excluding forward
exchange contracts, interest rate protection agreements and the Senior Notes
and Senior Debentures) approximates carrying value as they were based on terms
that continue to be available to the Company from its lenders.

   Off Balance Sheet Risk: The Company has certain receivables, payables and
borrowings denominated in currencies other than the functional currency of the
Company and/or its subsidiaries. The Company hedges certain of these exposures
by entering into forward exchange contracts. Gains and losses related to these
hedges are recognized in income as part of, and concurrent with the hedged
transactions. The Company does not use derivative financial instruments for
trading or speculative purposes.

   The table below summarizes the contractual amounts of the Company's forward
exchange contracts at December 31, 1998, all of which mature within 90 days.
Due to the short term maturity of these contracts, the fair value at December
31, 1998 approximates the nominal amounts. The foreign currency amounts have
been translated into U.S. dollars using applicable exchange rates at December
31, 1998.

   SFAS 133: On June 15, 1998, the Financial Accounting Standards Board issued
SFAS 133, "Accounting for Derivatives and Hedging Activities," effective for
fiscal years beginning after June 15, 1999 (January 1, 2000 for the Company).
SFAS 133 requires that all derivative instruments be recorded on the balance
sheet at their face value. Changes in the fair value of derivatives are
recorded each period in net income or as Comprehensive income, depending on
whether a derivative is designated as part of a hedge transaction and, if it
is, the type of hedge transaction. The Company is currently evaluating the
implications of this new pronouncement but, due to the Company's limited use of
derivative instruments, the adoption of SFAS 133 is not expected to have a
significant effect on the Company's results of operations or its financial
position.

NOTE 8--PENSION AND OTHER POSTRETIREMENT BENEFITS

   Domestic Pension Plans: The Company has adopted SFAS 132, Employers'
Disclosures about Pensions and Other Postretirement Benefits. SFAS 132 revises
the employer's disclosure presentation but does not change the measurement or
recognition of these plans.

   The Company has several noncontributory defined benefit pension and other
postretirement benefit plans covering substantially all of its United States
employees. The benefits for these plans are based primarily on years of
credited service and average compensation as defined under the respective plan
provisions. the Company's funding policy is to contribute amounts to the plans
sufficient to meet the minimum funding requirements set forth in the Employee
Retirement Income Security Act of 1974, plus such additional amounts as to the
Company may determine to be appropriate from time to time.

   The Company also sponsors defined contribution plans for its salaried and
certain union employees. Contributions relating to defined contribution plans
are made based upon the respective plan provisions.

   The projected benefit obligation, accumulated benefit obligation and the
fair value of plan assets for pension plans with accumulated benefit
obligations in excess of the plan assets were $42, $40 and $28, respectively,
for the year ended December 31, 1998.

   Assumed health care cost trend rates have a significant effect on the
amounts reported for the health care plans. A 1% increase or decrease in
assumed health care cost trend rates would affect service and interest
components of postretirement health care benefit cost by $1 for the year ended
December 31, 1998. The effect on the accumulated postretirement benefit
obligation would be $8 for the year ended December 31, 1998.

   Foreign Benefit Arrangements: The Company's foreign subsidiaries have
several defined benefit plans. the assets of these plans are held separately
from the Company in independent funds.

   Where required, the contributions are determined by a qualified actuary
every three years. the most recent such valuation was April 1, 1998.
Assumptions were 8% per year for return on investment, 8% per year for salary
increases and 4% per year for present and future pension increases.

   The aggregate market value of the plan assets was $110, approximately 120%
of the benefit obligations, after allowing for expected future increases in
earnings.

NOTE 9--EMPLOYEE BENEFIT PLANS

   The Company adopted a Long Term Stock Incentive Plan ("Stock Incentive
Plan") for the purpose of enhancing the profitability and value of the Company
for the benefit of its shareholders. A maximum of 3,909,000 shares of Common
Stock may be issued or used for reference purposes pursuant to the Stock
Incentive Plan.

   The Stock Incentive Plan provides for the following types of awards to
employees: (i) stock options, including incentive stock options and non-
qualified stock options; (ii) stock appreciation rights; (iii) restricted
stock; (iv) performance units; and (v) performance shares. The vesting schedule
for granted restricted stock awards is as follows: (i) three equal tranches
aggregating 25% of the total award will vest in each of October 1999, 2000 and
2001; and (ii) three equal tranches aggregating 75% of the total award will be
subject to the achievement of "value creation" performance criteria established
by the Compensation Committee for each of the three performance cycles
commencing January 1, 1997 and ending December 31, 1999, 2000 and 2001,
respectively. If and to the extent such criteria are achieved, half of the
earned portion of a tranche relating to a particular performance-based cycle of
the award will vest immediately and the remainder will vest in five equal
annual installments commencing on the first anniversary of the end of the
cycle.

   Options granted under the Stock Incentive Plan vest three years from the
date of grant and expire ten years from the date of grant. All grants under the
Stock Incentive Plan fully vest in the event of a change-in-control (as defined
by the plan) of the Company, or in the case of employees of a subsidiary of the
Company, a change-in-control of the relevant subsidiary.

   The Company has authorization under the Stock Incentive Plan to grant awards
for up to an additional 184,256 shares at December 31, 1998.

   Unearned restricted stock, based on the market value of the shares at each
balance sheet date, is included as a separate component of Shareholders' equity
and amortized over the restricted period.

   For options outstanding at December 31, 1998, the range of exercise prices
was $18.00 to $34.875 per share, and the weighted-average remaining contractual
life was 9 years. The weighted-average fair value at December 31, 1998, was $4
per share option.

   The Company adopted the disclosure-only provisions of SFAS 123, "Accounting
for Stock-Based Compensation." The impact on net income and earnings per share
would not have been materially different had compensation expense for the
Company's incentive plan been determined based on the fair value of such grants
on the grant date in accordance with the provisions of SFAS 123.

   The Company has a deferred compensation plan that permits officers,
directors and certain management employees to defer a portion of their
compensation on a pre-tax basis in the form of Common Stock. A rabbi trust (the
"Trust") has been established to hold shares of Common Stock purchased in open
market transactions to fund this obligation. Shares purchased by the Trust are
reflected as Treasury stock and along with the related obligation for this
plan, are included in Shareholders' equity. At December 31, 1998, 256,987
shares have been purchased for $7 and are held in the Trust.

   The Company has a Long Term Incentive Plan for certain management employees.
The plan provides for awards of Common Stock to be granted if annual EVA(R)
targets are achieved. Such earned shares are held in a trust until certain
vesting provisions are satisfied. Such awards will vest on the later of: (a)
three years following the date of grant or (b) achievement of cumulative
positive EVA(R) during a three-consecutive-year period. Unvested shares will be
forfeited after six years.

NOTE 10--RELATED PARTY TRANSACTIONS

   One of the Company's subsidiaries purchases ethylene from Equistar at
market-related prices pursuant to an agreement made in connection with the
formation of Equistar. Under the agreement the subsidiary is required to
purchase 100% of its ethylene requirements for its La Porte, Texas, facility up
to a maximum of 330 million pounds per year. The initial term of the contract
expires December 1, 2000. Thereafter, the contract automatically renews
annually. either party may terminate on one year's notice.

NOTE 11--COMMITMENTS AND CONTINGENCIES

   The Company is subject, among other things, to several proceedings under the
Federal Comprehensive Environmental Response Compensation and Liability Act and
other federal and state statutes or agreements with third parties. These
proceedings are in various stages ranging from initial investigation to active
settlement negotiations to implementation of the clean-up or remediation of
sites. Additionally, certain of the Company's subsidiaries are defendants or
plaintiffs in lawsuits that have arisen in the normal course of business
including those relating to commercial transactions and product liability.
While certain of the lawsuits involve allegedly significant amounts, it is
management's opinion, based on the advice of counsel, that the ultimate
resolution of such litigation will not have a material adverse effect on the
Company's financial position or results of operations. The Company believes
that the range of potential liability for these matters, collectively, which
primarily relate to environmental remediation activities, is between $150 and
$176 and has accrued $176 as of December 31, 1998.

   The Company has various contractual obligations to purchase raw materials
used in its production of TiO\\2\\ and fragrance and flavor chemicals.
Commitments to purchase ore used in the production of TiO\\2\\ are generally 1-
to 8-year contracts with competitive prices generally determined at a fixed
amount subject to escalation for inflation. Total commitments to purchase ore
for TiO\\2\\ aggregate approximately $1,100 and expire between 1999 and 2002.
Commitments to acquire crude sulfate turpentine, used in the production of
fragrance chemicals, are generally pursuant to 1-to 5-year contracts with
prices based on the market price and which expire between 1999 and 2008.

   The Company is organized under the laws of Delaware and is subject to United
States federal income taxation of corporations. However, in order to obtain
clearance from the United Kingdom Inland Revenue as to the tax-free treatment
of the Demerger stock dividend for United Kingdom tax purposes for Hanson and
Hanson's shareholders, Hanson agreed with the United Kingdom Inland Revenue
that the Company will continue to be centrally managed and controlled in the
United Kingdom at least until September 30, 2001. Hanson also agreed that the
Company's Board of Directors will be the only medium through which strategic
control and policy making powers are exercised, and that board meetings almost
invariably will be held in the United Kingdom during this period. The Company
has agreed not to take, or fail to take, during such five-year period, any
action that would result in a breach of, or constitute non-compliance with, any
of the representations and undertakings made by Hanson in its agreement with
the United Kingdom Inland Revenue and to indemnify Hanson against any liability
and penalties arising out of a breach of such agreement. The Company's By-Laws
provide for similar constraints. The Company and Hanson estimate that such
indemnification obligation would have amounted to approximately $421 if it had
arisen during the twelve months ended September 30, 1997, and that such
obligation will decrease by approximately $84 on each October 1 prior to
October 1, 2001, when it will expire.

   If the Company ceases to be a United Kingdom tax resident at any time, the
Company will be deemed for purposes of United Kingdom corporation tax on
chargeable gains to have disposed of all of its assets at such time. In such a
case, the Company would be liable for United Kingdom corporation tax on
chargeable gains on the amount by which the fair market value of those assets
at the time of such deemed disposition exceeds the Company's tax basis in those
assets. The tax basis of the assets would be calculated in pounds sterling,
based on the fair market value of the assets (in pounds sterling) at the time
of acquisition of the assets by the Company, adjusted for United Kingdom
inflation. Accordingly, in such circumstances, the Company could incur a tax
liability even though it has not actually sold the assets and even though the
underlying value of the asset may not actually have appreciated (due to
currency movements). Since it is impossible to predict the future value of the
Company's assets, currency movements and inflation rates, it is impossible to
predict the magnitude of such liability, should it arise.

           OCCIDENTAL CHEMICAL HOLDING CORPORATION AND SUBSIDIARIES

                      NOTES TO CONSOLIDATED BALANCE SHEET

                                 June 30, 1999

                                   UNAUDITED

(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES--

 Nature of operations--

   Occidental Chemical Holding Corporation (OCHC) manufactures and markets,
domestically and internationally, a variety of basic chemicals, including
chlorine, caustic soda, polyvinyl chloride (PVC), vinyl chloride monomer (VCM)
and ethylene dichloride (EDC), as well as specialty chemicals. OCHC also has
an interest in petrochemicals through its 29.5 percent ownership in the
Equistar Chemicals, LP petrochemical limited partnership (Equistar). The
balance sheet of OCHC at June 30, 1999 and notes thereto is presented because
OCHC guarantees to Equistar certain obligations of OCHC's indirect subsidiary
that serves as a general partner of Equistar. See Note 3. OCHC is a
multinational organization whose outstanding common shares are all indirectly
owned by Occidental Petroleum Corporation (Occidental).

 Principles of consolidation--

   The consolidated balance sheet includes the accounts of OCHC, a California
corporation, and all majority-owned subsidiaries. All material intercompany
accounts have been eliminated. Investments in less than majority-owned
enterprises are accounted for on the equity method. See Note 3.

 Basis of presentation--

   The accompanying unaudited consolidated balance sheet has been prepared
pursuant to the rules and regulations of the Securities and Exchange
Commission. Certain information and disclosures normally included in notes to
consolidated financial statements have been condensed or omitted pursuant to
such rules and regulations, but resultant disclosures are in accordance with
generally accepted accounting principles as they apply to interim reporting.
The consolidated balance sheet should be read in conjunction with the OCHC
audited balance sheet and the notes thereto as of December 31, 1998 (1998
Balance Sheet).

   In the opinion of Occidental's management, the accompanying consolidated
balance sheet contains all adjustments (consisting only of normal recurring
adjustments) necessary to present fairly OCHC's consolidated financial
position as of June 30, 1999.

   Reference is made to Note 1 to the 1998 Balance Sheet for a summary of
significant accounting policies.

 Risks and uncertainties--

   The process of preparing consolidated financial statements in conformity
with generally accepted accounting principles requires the use of estimates
and assumptions regarding certain types of assets, liabilities, revenues and
expenses. Such estimates primarily relate to unsettled transactions and events
as of the date of the consolidated financial statements. Accordingly, upon
settlement, actual results may differ from estimated amounts, generally not by
material amounts. Management believes that these estimates and assumptions
provide a reasonable basis for the fair presentation of OCHC's financial
position.

   Included in the accompanying consolidated balance sheet are deferred tax
assets of $343 million as of June 30, 1999, the noncurrent portion of which is
netted against deferred income tax liabilities. Realization of these assets is
dependent upon OCHC generating sufficient future taxable income. OCHC expects
to realize the recorded deferred tax assets through future operating income
and reversal of taxable temporary differences.

 Environmental costs

   Environmental expenditures that relate to current operations are expensed or
capitalized as appropriate. Reserves for estimated costs that relate to
existing conditions caused by past operations and that do not contribute to
current or future revenue generation are recorded when environmental remedial
efforts are probable and the costs can be reasonably estimated. In determining
the reserves, OCHC uses the most current information available, including
similar past experiences, available technology, regulations in effect, the
timing of remediation and cost-sharing arrangements. The environmental reserves
are based on management's estimate of the most likely cost to be incurred and
are reviewed periodically and adjusted as additional or new information becomes
available. Probable recoveries or reimbursements are recorded as an asset. The
environmental reserves are included in accrued liabilities and other noncurrent
liabilities and amounted to $55.2 million and $39.5 million, respectively, at
June 30, 1999.

   Environmental reserves are discounted only when the aggregate amount of the
estimated costs for a specific site and the timing of cash payments are
reliably determinable. As of June 30, 1999, reserves that were recorded on a
discounted basis were not material.

   On June 30, 1998, OCHC transferred environmental remediation liabilities
associated with certain designated properties, amounting to $281 million as of
such date, to Miller Springs Remediation Management, Inc. (MS), an 87.5%
indirectly owned subsidiary of Occidental. This transfer was made in order to
more effectively manage the environmental remediation liabilities and related
costs at the designated properties and to provide financial incentives for the
efficient resolution of such liabilities. In connection with this transfer, MS
assumed full responsibility for remediation of the designated properties
covered by these liabilities, including any future changes in the cost or scope
of such remediation. However, under the Comprehensive Environmental Response,
Compensation and Liability Act (CERCLA) and analogous state laws, courts have
discretion under certain circumstances to hold potentially responsible parties
jointly and severally liable until all required remediation efforts have been
completed. Accordingly, even though MS has fully assumed remediation
liabilities at the designated properties, OCHC may be held liable until the
required remediation efforts at those properties are completed or for any
remaining liability not assumed or funded by MS.

 Hedging activities--

   OCHC periodically uses forward exchange contracts to hedge the risk
associated with fluctuations in foreign currency exchange rates. OCHC does not
use forward exchange contracts for speculative or trading purposes. Gains and
losses on foreign currency forward exchange contracts that hedge identifiable
future commitments are deferred until recognized when the related item being
hedged is settled. The amounts deferred at June 30, 1999 were immaterial.

 Accounting changes--

   In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards (SFAS) No. 133--"Accounting for Derivative
Instruments and Hedging Activities," which establishes accounting and reporting
standards for derivative instruments and hedging activities. It requires that
an entity recognize all derivatives in the statement of financial position and
measure those instruments at fair value. OCHC must implement SFAS No. 133 by
the first quarter of 2001 and has not yet made a final determination of its
impact on the financial statements.

(2) ACQUISITIONS AND DISPOSITIONS--

   To further strengthen its PVC and VCM position, Occidental, in May 1999,
entered into an agreement with The Geon Company (Geon) providing, among other
things, for the formation of two partnerships. OCHC has a 76 percent
controlling interest in a PVC partnership which is the larger of the
partnerships and a 10 percent interest in a compound partnership. Its interest
represents an increase in its chlorovinyls capacity compared to its contributed
PVC/VCM assets. The PVC partnership also entered into long-term agreements to
supply PVC and VCM to Geon's compounding operations.

(3) INVESTMENTS--

   Investments in companies in which OCHC has a voting stock interest of no
more than 50 percent and certain partnerships are accounted for on the equity
method. At June 30, 1999, OCHC's equity investments consisted of a 29.5%
interest in Equistar acquired in May 1998, an investment of approximately 29
percent in the common shares of Canadian Occidental Petroleum Ltd.
(CanadianOxy) and various chemical partnerships and joint ventures. The
aggregate market value of the investment in CanadianOxy, based on the quoted
market price for CanadianOxy common shares, was $649 million at June 30, 1999,
compared with an aggregate book value of $215 million. At June 30, 1999, OCHC's
investment in equity investees exceeded the historical underlying equity in net
assets by approximately $159 million, which is being amortized into income over
periods not exceeding 40 years.

   An indirect subsidiary of OCHC, Occidental Petrochem Partner GP, Inc.
("General Partner") holds a 0.001% general partner interest in Equistar. The
General Partner has no independent operations of its own and certain of its
obligations as general partner have, under an agreement signed between OCHC and
Equistar, been guaranteed by OCHC. Accordingly, the balance sheet of OCHC, as
guarantor of certain of the General Partner's obligation, is presented at June
30, 1999. The General Partner had assets consisting of its investment in
Equistar of $324,000, and invested capital, after intercompany balances, of
$324,000 as of June 30, 1999.

(4) INVENTORIES--

   Inventories of approximately $247 million were valued under the last-in,
first-out (LIFO) cost method which did not exceed market value, at June 30,
1999. The remaining inventories are stated at cost determined on the first-in,
first-out (FIFO) and weighted-average-cost methods and did not exceed market
value.

   Inventories consisted of the following as of June 30, 1999 (in thousands):

      Accrued taxes, other than income taxes........................... $34,377
      Salaries, wages and other compensation........................... $42,983
</TABLE>

(6) CONTINGENT LIABILITIES AND COMMITMENTS--

 Lawsuits--

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

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

 Other contingencies and commitments--

   OCHC has entered into agreements providing for minimum future payments to
purchase raw materials, steam and water. At June 30, 1999 the net present value
of the fixed and determinable portion of the obligations under these agreements
are as follows (in thousands):

   OCHC purchases VCM from an equity method investee under the terms of a VCM
purchase agreement that runs for the life of the equity method investee. The
agreement requires OCHC to purchase at market prices a minimum of sixty percent
of the first billion pounds of VCM produced and the first 100 million pounds

produced in excess of one billion pounds each year. OCHC is also obligated to
purchase all of its ethylene feedstock requirements (not to exceed 2.55 billion
pounds per year) from Equistar through 2013.

   OCHC has certain other contingent liabilities and claims under contracts as
guarantor of debt and with regard to other potential obligations, all in the
ordinary course of business. In the opinion of management, such contingent
liabilities will not result in any significant financial liability in relation
to the financial position and results of operations of OCHC.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Board of Directors,
Occidental Chemical Holding Corporation:

We have audited the accompanying consolidated balance sheet of Occidental
Chemical Holding Corporation (a California corporation and indirect wholly-
owned subsidiary of Occidental Petroleum Corporation) and subsidiaries as of
December 31, 1998. The consolidated balance sheet is the responsibility of
Occidental Chemical Holding Corporation's management. Our responsibility is to
express an opinion on the consolidated balance sheet based on our audit. We did
not audit the financial statements of Equistar Chemicals, LP, the investment
which is reflected in the accompanying consolidated balance sheet at December
31, 1998 using the equity method of accounting and for which the summarized
financial information is contained in Note 4. The investment in Equistar
Chemicals, LP represents 15% of total assets. The financial statements of
Equistar Chemicals, LP were audited by other auditors whose report has been
furnished to us, and our opinion, insofar as it relates to the amounts included
for Equistar Chemicals, LP, is based solely on the report of other auditors.

We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the consolidated balance sheet is free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the consolidated balance sheet. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audit provides a reasonable basis
for our opinion.

In our opinion, based on our audit and the report of other auditors, the
consolidated balance sheet referred to above presents fairly, in all material
respects, the financial position of Occidental Chemical Holding Corporation and
subsidiaries as of December 31, 1998, in conformity with generally accepted
accounting principles.

                      NOTES TO CONSOLIDATED BALANCE SHEET

                               December 31, 1998

(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES--

 Nature of operations --

   Occidental Chemical Holding Corporation (OCHC) manufactures and markets,
domestically and internationally, a variety of basic chemicals, including
chlorine, caustic soda, polyvinyl chloride (PVC), vinyl chloride monomer (VCM)
and ethylene dichloride (EDC), as well as specialty chemicals. OCHC also has an
interest in petrochemicals through its 29.5 percent ownership in the Equistar
Chemicals, LP petrochemical limited partnership (Equistar). The balance sheet
of OCHC at December 31, 1998 and notes thereto is presented because OCHC
guarantees to Equistar certain obligations of OCHC's indirect subsidiary that
serves as a general partner of Equistar. See Note 4. OCHC is a multinational
organization whose outstanding common shares are all indirectly owned by
Occidental Petroleum Corporation (Occidental).

 Principles of consolidation--

   The consolidated balance sheet includes the accounts of OCHC, a California
corporation, and all majority-owned subsidiaries. All material intercompany
accounts have been eliminated. Investments in less than majority-owned
enterprises are accounted for on the equity method. See Note 4.

 Risks and uncertainties--

   The process of preparing consolidated financial statements in conformity
with generally accepted accounting principles requires the use of estimates and
assumptions regarding certain types of assets, liabilities, revenues and
expenses. Such estimates primarily relate to unsettled transactions and events
as of the date of the consolidated financial statements. Accordingly, upon
settlement, actual results may differ from estimated amounts, generally not by
material amounts. Management believes that these estimates and assumptions
provide a reasonable basis for the fair presentation of OCHC's financial
position.

   Included in the accompanying consolidated balance sheet are deferred tax
assets of $343 million as of December 31, 1998, the noncurrent portion of which
is netted against deferred income tax liabilities. Realization of these assets
is dependent upon OCHC generating sufficient future taxable income. OCHC
expects to realize the recorded deferred tax assets through future operating
income and reversal of taxable temporary differences.

 Relationship with Occidental Petroleum Corporation--

   As an indirect, wholly-owned subsidiary of Occidental, OCHC engages in
transactions with Occidental and its other subsidiaries relating to tax
sharing, insurance, borrowing, cash management, guarantees, advisory services
and other matters. Occidental furnished OCHC with data processing and other
services for which OCHC has been charged at Occidental's approximate cost.
OCHC's deficiency in or excess of funds is financed by or transferred to
Occidental in conjunction with a consolidated cash management system. Interest
was computed on the average intercompany balance between Occidental and OCHC at
an agreed upon average annual rate of 6 percent in 1998. OCHC also has a note
payable to Occidental as of December 31, 1998 with an interest rate of 8.25
percent. Additionally, OCHC transferred to an affiliate certain trade
receivables under a revolving sale program discussed in Note 3.

 Translation of foreign currencies--

   OCHC has foreign subsidiaries and investments accounted for under the equity
method located in Canada, Latin America, the Far East and Europe. Assets and
liabilities of the foreign subsidiaries as well as OCHC's investments in less
than majority-owned foreign companies are translated into U.S. dollars at the
exchange rate

                NOTES TO CONSOLIDATED BALANCE SHEET--(Continued)

prevailing at the balance sheet date. Revenue and expense accounts for these
subsidiaries are translated using the weighted average exchange rate during the
period. The net effect of these transactions is included in accumulated other
comprehensive income.

 Cash and cash equivalents--

   Cash equivalents consist of highly liquid money-market mutual funds and bank
deposits with initial maturities of three months or less. Cash equivalents
totaled approximately $11 million at December 31, 1998.

 Long-term receivables--

   Long-term receivables at December 31, 1998 include $11 million of notes
receivable from the sale of a business in 1996.

 Other assets--

   The excess of cost over fair value of net assets at acquisition date is
amortized over 40 years. The net book value of these assets was $78.7 million
at December 31, 1998. Other assets also include certain tangible and intangible
assets that are amortized over the estimated periods to be benefited (3-28
years).

   In April 1998, the American Institute of Certified Public Accountants issued
Statement of Position 98-5, "Reporting on the Costs of Start-Up Activities"
(SOP 98-5), which requires that costs of start-up activities be expensed as
incurred. In addition, start-up costs that are currently capitalized must be
written off when SOP 98-5 is adopted. Occidental implemented SOP 98-5 effective
January 1, 1999, and OCHC recorded a charge of $15 million, which is net of an
$8 million income tax benefit, to reflect the cumulative effect of this change
in accounting principle for both its consolidated subsidiaries and its equity
investments.

 Environmental costs--

   Environmental expenditures that relate to current operations are expensed or
capitalized as appropriate. Reserves for estimated costs that relate to
existing conditions caused by past operations and that do not contribute to
current or future revenue generation are recorded when environmental remedial
efforts are probable and the costs can be reasonably estimated. In determining
the reserves, OCHC uses the most current information available, including
similar past experiences, available technology, regulations in effect, the
timing of remediation and cost-sharing arrangements. The environmental reserves
are based on management's estimate of the most likely cost to be incurred and
are reviewed periodically and adjusted as additional or new information becomes
available. Probable recoveries or reimbursements are recorded as an asset. The
environmental reserves are included in accrued liabilities and other noncurrent
liabilities and amounted to $55.2 million and $83 million, respectively, at
December 31, 1998.

   Environmental reserves are discounted only when the aggregate amount of the
estimated costs for a specific site and the timing of cash payments are
reliably determinable. As of December 31, 1998, reserves that were recorded on
a discounted basis were not material.

   On June 30, 1998, OCHC transferred environmental remediation liabilities
associated with certain designated properties, amounting to $281 million as of
such date, to Miller Springs Remediation Management, Inc. (MS), an 87.5%
indirectly owned subsidiary of Occidental. This transfer was made in order to
more effectively manage the environmental remediation liabilities and related
costs at the designated properties and to provide financial incentives for the
efficient resolution of such liabilities. In connection with this transfer, MS
assumed full responsibility for remediation of the designated properties
covered by these liabilities,

                                     F-136

            OCCIDENTAL CHEMICAL HOLDING CORPORATION AND SUBSIDIARIES

                NOTES TO CONSOLIDATED BALANCE SHEET--(Continued)

including any future changes in the cost or scope of such remediation. However,
under the Comprehensive Environmental Response, Compensation and Liability Act
(CERCLA) and analogous state laws, courts have discretion under certain
circumstances to hold potentially responsible parties jointly and severally
liable until all required remediation efforts have been completed. Accordingly,
even though MS has fully assumed remediation liabilities at the designated
properties, OCHC may be held liable until the required remediation efforts at
those properties are completed or for any remaining liability not assumed or
funded by MS.

 Hedging activities--

   OCHC periodically uses forward exchange contracts to hedge the risk
associated with fluctuations in foreign currency exchange rates. OCHC does not
use forward exchange contracts for speculative or trading purposes. Gains and
losses on foreign currency forward exchange contracts that hedge identifiable
future commitments are deferred until recognized when the related item being
hedged is settled. The amounts deferred at December 31, 1998 were immaterial.
At December 31, 1998, OCHC had foreign currency forward exchange contracts
which hedged a notional amount of approximately $23 million of current
liabilities. These contracts matured in January 1999. The notional amount of
OCHC's foreign currency forward exchange contracts does not generally represent
amounts exchanged by the parties, and thus, is not a measure of the exposure of
OCHC or of the cash requirements relating to these contracts. The amounts
exchanged are calculated by reference to the notional amounts and by other
terms of the derivatives.

 Fair value of financial instruments--

   OCHC values financial instruments as required by Statement of Financial
Accounting Standards (SFAS) No. 107. The carrying amounts of cash and cash
equivalents and short-term notes payable approximate fair value because of the
short maturity of those instruments. OCHC estimates the fair value of its long-
term debt based on the quoted market prices for the same or similar issues or
on the yields offered to OCHC for debt of similar rating and similar remaining
maturities. The estimated fair value of OCHC's long-term debt at December 31,
1998 was $195.0 million compared with a carrying value of $189.2 million. See
Note 8.

   The carrying value of other on-balance sheet financial instruments
approximates fair value. However, the fair value of due from Occidental and
affiliates, net cannot be practicably determined due to the related party
nature of the balances. The cost, if any, to terminate off-balance sheet
financial instruments is not significant.

 Accounting changes--

   In June 1998, the Financial Accounting Standards Board issued SFAS No. 133--
"Accounting for Derivative Instruments and Hedging Activities," which
establishes accounting and reporting standards for derivative instruments and
hedging activities. It requires that an entity recognize all derivatives in the
statement of financial position and measure those instruments at fair value.
OCHC must implement SFAS No. 133 by the first quarter of 2001 and has not yet
made a final determination of its impact on the financial statements.

   Effective January 1, 1998, OCHC adopted the provisions of SFAS No. 132--
"Employers' Disclosures about Pensions and Other Postretirement Benefits." This
statement standardized the disclosure requirements for pensions and other
postretirement benefits and amends SFAS No. 87--"Employers' Accounting for
Pensions," SFAS No. 88--"Employers' Accounting for Settlements and Curtailments
of Defined Benefit Pension Plans" and SFAS No. 106--"Employers' Accounting for
Postretirement Benefits Other Than Pensions." The provisions of SFAS No. 132
are disclosure oriented and do not change the measurement or recognition of the
plans. Accordingly, the implementation of SFAS No. 132 did not have an impact
on OCHC's consolidated financial position.

(2) ACQUISITIONS AND DISPOSITIONS--

   To further strengthen its PVC and VCM position, Occidental, in December
1998, signed a definitive agreement with The Geon Company (Geon) providing,
among other things, for the formation of two partnerships. OCHC will have a 76
percent controlling interest in a PVC partnership which is the larger of the
partnerships and a 10 percent interest in a compound partnership. Its interests
represent an increase in its chlorovinyls capacity compared to its existing
contributed PVC/VCM assets. The PVC partnership will also enter into long-term
agreements to supply PVC and VCM to Geon's compounding operations. The
transaction closed in the second quarter of 1999, following satisfaction of
closing conditions, including approval from Occidental's Board of Directors and
Geon shareholders.

   In May 1998, OCHC contributed its ethylene, propylene, ethylene oxide and
ethylene glycol derivatives businesses (collectively, the petrochemicals
business) to the Equistar partnership in return for a 29.5% interest in such
partnership, receipt of approximately $420 million in cash and the assumption
by Equistar of approximately $205 million of OCHC capital lease obligations and
other liabilities. At December 31, 1998, Occidental guaranteed $625 million of
Equistar's debt related to these amounts. Lyondell Petrochemical Company
(Lyondell) and Millennium Chemicals, Inc. (Millennium), through their
respective subsidiaries, were the original partners of Equistar. Lyondell owns
41% of Equistar and OCHC and Millennium each own 29.5%. Following the closing
of the transaction, the assets and liabilities transferred to the partnership
(primarily property, plant and equipment, inventories and capital lease
liabilities) were removed from the balance sheet and an equity investment was
recorded.

(3) TRADE RECEIVABLES--

   During 1998, OCHC transferred, with limited recourse, to an affiliate
certain trade receivables under a revolving sale program in connection with the
ultimate sale for cash of an undivided ownership interest in such receivables
by the affiliate. OCHC has retained the collection responsibility with respect
to the receivables sold. An interest in new receivables is transferred monthly
in noncash transactions representing the net difference between newly created
receivables and collections made from customers. The net receivables balance
transferred as of December 31, 1998 was $300 million.

(4) INVESTMENTS--

   Investments in companies in which OCHC has a voting stock interest of no
more than 50 percent and certain partnerships are accounted for on the equity
method. At December 31, 1998, OCHC's equity investments consisted of a 29.5%
interest in Equistar acquired in May 1998, an investment of approximately 29
percent in the common shares of Canadian Occidental Petroleum Ltd.
(CanadianOxy) and various chemical partnerships and joint ventures. The
aggregate market value of the investment in CanadianOxy, based on the quoted
market price for CanadianOxy common shares, was $420 million at December 31,
1998, compared with an aggregate book value of $217 million. At December 31,
1998, OCHC's investment in equity investees exceeded the historical underlying
equity in net assets by approximately $162 million, which is being amortized
into income over periods not exceeding 40 years.

</TABLE>

   An indirect subsidiary of OCHC, Occidental Petrochem Partner GP, Inc.
("General Partner") holds a 0.001% general partner interest in Equistar. The
General Partner has no independent operations of its own and certain of its
obligations as general partner have, under an agreement signed between OCHC and
Equistar, been guaranteed by OCHC. Accordingly, the audited balance sheet of
OCHC, as guarantor of certain of the General Partner's obligation, is presented
at December 31, 1998. The General Partner had assets consisting of its
investment in Equistar of $325,000, and invested capital, after intercompany
balances, of $325,000 as of December 31, 1998.

(5) INVENTORIES--

   Inventories of approximately $253 million were valued under the last-in,
first-out (LIFO) cost method which did not exceed market value, at December 31,
1998. The remaining inventories are stated at cost determined on the first-in,
first-out (FIFO) and weighted-average-cost methods and did not exceed market

</TABLE>

(6) PROPERTY, PLANT AND EQUIPMENT--

   Property additions and major renewals and improvements are capitalized at
cost. Leases that qualify as capital leases have been capitalized at the
present value of future minimum lease payments. Depreciation of plant and
equipment is primarily provided using the unit-of-production method based on
estimated total productive life.

   Interest costs incurred in connection with major capital expenditures are
capitalized and amortized over the lives of the related assets. Capitalized
interest is calculated based on the average borrowing rate of Occidental,
unless a specific new borrowing is associated with the qualifying asset, in
which case the interest rate on that borrowing is used as the capitalization
rate. The amount of interest capitalized was $11.0 million in 1998.

(10) CONTINGENT LIABILITIES AND COMMITMENTS--

 Lawsuits--

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

   It is impossible at this time to determine the ultimate liabilities that
OCHC and its subsidiaries may incur resulting from the foregoing lawsuits,
claims and proceedings. Several of these matters may involve substantial
amounts and if these were to be ultimately resolved unfavorably to the full
amount of their maximum potential exposure, an event not currently anticipated,
it is possible that such event could have a material adverse effect

upon OCHC's financial position or results of operations. However, in
management's opinion, after taking into account reserves, it is unlikely that
any of the foregoing matters will have a material adverse effect upon OCHC's
financial position.

 Other contingencies and commitments--

   OCHC has entered into agreements providing for minimum future payments to
purchase raw materials, steam and water. At December 31, 1998 the net present

   OCHC purchases VCM from an equity method investee under the terms of a VCM
purchase agreement that runs for the life of the equity method investee. The
agreement requires OCHC to purchase at market prices a minimum of sixty percent
of the first billion pounds of VCM produced and the first 100 million pounds
produced in excess of one billion pounds each year. Total purchases under the
agreement were $184 million in 1998. OCHC is also obligated to purchase all of
its ethylene feedstock requirements (not to exceed 2.55 billion pounds per
year) from Equistar through 2013. Purchases under this agreement were $161
million in 1998.

   OCHC has certain other contingent liabilities and claims under contracts as
guarantor of debt and with regard to other potential obligations, all in the
ordinary course of business. In the opinion of management, such contingent
liabilities will not result in any significant financial liability in relation
to the financial position of operations of OCHC.

(11) DOMESTIC AND FOREIGN INCOME AND OTHER TAXES--

   OCHC and its 80 percent or more owned domestic subsidiaries are included in
the consolidated U.S. federal income tax return and in certain unitary state
income tax returns of Occidental, which allocates a portion of the income tax
provision for these returns to OCHC. Deferred income taxes are recorded at
enacted rates to recognize the future effects of temporary differences which
arise between financial statement assets and liabilities and their basis for
income tax reporting purposes. Current and deferred income tax provisions are
based on taxable income determined as though OCHC filed as an independent
company, making the same tax return elections used in Occidental's consolidated
U.S. federal return. Occidental also permits OCHC to recognize income tax
benefits for current year operating losses and deductible temporary differences
without limiting such benefits. Any unpaid current income tax allocations are
included in due from Occidental and affiliates, net, in the accompanying
consolidated balance sheet. OCHC also records current and deferred income tax
provisions for operations required to be reported in separate tax returns, the
unpaid current portion of which is classified as domestic and foreign income
taxes payable in the accompanying consolidated balance sheet.

   Deferred tax liabilities of approximately $44 million at December 31, 1998
have not been recognized for temporary differences of $95 million related to
OCHC's investment in certain foreign subsidiaries, primarily as a result of
unremitted earnings of these subsidiaries, as it is OCHC's intention,
generally, to reinvest such earnings permanently.

                NOTES TO CONSOLIDATED BALANCE SHEET--(Continued)


   Deferred income taxes reflect the future tax consequences of temporary
differences between the tax bases of assets and liabilities and their financial
reporting amounts. At December 31, 1998, OCHC had deferred tax assets of $343
million and deferred tax liabilities of $1.054 billion.

   The tax effects of temporary differences at December 31, 1998 were as
follows (in millions):

   In connection with the transfer of certain environmental remediation
liabilities to MS in June 1998, approximately $109 million of deferred tax
assets were transferred by OCHC through the intercompany account included in
due from Occidental and affiliates, net as of December 31, 1998.

   OCHC is subject to audit by taxing authorities for varying periods in
various tax jurisdictions. Management believes that any required adjustments to
OCHC's tax liabilities will not have a material adverse impact on its financial
position.

(12) STOCK INCENTIVE PLANS--

   Certain OCHC executives participate in various Occidental stock incentive
plans. During 1998, 558,000 options were granted. Generally, these options vest
over three years with a maximum term of ten years and one month.

   In addition, 9,623 of Occidental's $.20 par value restricted stock were
awarded during the year ended December 31, 1998. These shares vest after four
years (five years for awards issued prior to December 1995) or earlier under
certain conditions.

   Performance stock awards were made to various executive officers pursuant to
the 1995 Incentive Stock Plan. The number of shares of common stock to be
received, under these awards, by such officers 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 for such period. Based on
Occidental's ranking among its peers, the grantees will receive shares of
common stock in an amount ranging from zero to 175 percent of the Target Share
Award (as such amount is defined in the grant). The shares vest or fail to vest
by the end of the four-year performance term. In 1998, 16,947 shares were
awarded to OCHC officers at a weighted-average grant-date value of $29.3125 per
share.

   In 1997, 875,000 performance stock options were granted to certain executive
officers at an exercise price of $25.375. These options expire ten years from
the grant date and have no value unless and until one of the following events
occur, at which time the grants become fully vested and exercisable: for twenty
consecutive trading days, the New York Stock Exchange closing price of
Occidental's common stock must be a) $30 or

            OCCIDENTAL CHEMICAL HOLDING CORPORATION AND SUBSIDIARIES

                NOTES TO CONSOLIDATED BALANCE SHEET--(Continued)

more per share within the first three years after grant date; b) $35 or more
per share after the third year and through the fifth year; or c) $40 or more
per share from the sixth year until expiration. None of the options were
exercisable in 1998. Any income effect will be recognized at the time the
options are exercisable.

(13) RETIREMENT PLANS AND POSTRETIREMENT BENEFITS--

   OCHC participates in various defined contribution retirement plans sponsored
by Occidental for its salaried, domestic union and nonunion hourly, and certain
foreign national employees that provide for periodic contributions by OCHC
based on plan-specific criteria, such as base pay, age level, and/or employee
contributions.

   OCHC provides medical and dental benefits and life insurance coverage for
certain active, retired and disabled employees and their eligible dependents.
The benefits generally are funded by OCHC as the benefits are paid during the
year. The cost of providing these benefits is based on claims filed and
insurance premiums paid for the period.

   Pension costs for OCHC's defined benefit pension plans, determined by
independent actuarial valuations, are generally funded by payments to trust
funds, which are administered by independent trustees.

   In 1998, OCHC recorded adjustments to accumulated other comprehensive income
of less than $1 million, to reflect the net-of-tax difference between the
additional liability required under pension accounting provisions and the
corresponding intangible asset.

   OCHC's defined benefit pension and postretirement benefit plans are accrued
based on various assumptions and discount rates, as described below. The
actuarial assumptions used could change in the near term as a result of changes
in expected future trends and other factors which, depending on the nature of
the changes, could cause increases or decreases in the liabilities accrued.

   The following table sets forth the reconciliation of the 1998 beginning and
ending balances of the benefit obligation for OCHC's defined benefit pension
and postretirement benefit plans (in thousands):

</TABLE>

   The projected benefit obligation, accumulated benefit obligation and fair
value of plan assets for defined benefit pension plans with accumulated benefit
obligations in excess of plan assets were $42 million, $35 million and $30
million, respectively, as of December 31, 1998.

   The weighted average discount rate used in determining the benefit
obligations was 7 percent in 1998. The weighted average rate of increase in
future compensation levels used in determining the benefit obligations was
approximately 5 percent in 1998. The expected weighted average long-term rate
of return on assets was 8 percent in 1998.

   The postretirement benefit obligation was determined by application of the
terms of medical and dental benefits and life insurance coverage, including the
effect of established maximums on covered costs, together with relevant
actuarial assumptions and health care cost trend rates projected at a Consumer
Price Index (CPI) increase of 2.5 percent as of December 31, 1998 (beginning in
1993, participants other than certain union employees pay for all medical cost
increases in excess of increases in the CPI). For certain union employees, the
health care cost trend rates were projected at annual rates ranging ratably
from 8 percent in 1998 to 5 percent through the year 2004 and level thereafter.
A one percent increase or a one percent decrease in these assumed health care
cost trend rates would result in an increase of $11 million or a reduction of
$9 million in the postretirement benefit obligation as of December 31, 1998.

OCHC's consolidated balance sheet for the defined pension and postretirement
benefit plans at December 31, 1998 (in thousands):
