                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Partnership Governance Committee
of EQUISTAR CHEMICALS, LP:

    In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of income and comprehensive income, of partners' capital
and of cash flows present fairly, in all material respects, the financial
position of Equistar Chemicals, LP (the 'Partnership') and its subsidiaries at
December 31, 2000 and 1999, and the results of their operations and their cash
flows for the years then ended, in conformity with accounting principles
generally accepted in the United States of America. 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 auditing standards
generally accepted in the United States of America, 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 our opinion.

                             EQUISTAR CHEMICALS, LP
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Formation of the Partnership and Operations

    Pursuant to a partnership agreement ('Partnership Agreement'), Lyondell
Chemical Company ('Lyondell') and Millennium Chemicals Inc. ('Millennium')
formed Equistar Chemicals, LP ('Equistar' or 'Partnership'), a Delaware limited
partnership, which commenced operations on December 1, 1997. From December 1,
1997 to May 15, 1998, Equistar was owned 57% by Lyondell and 43% by Millennium.
Lyondell owns its interest in Equistar through two wholly owned subsidiaries,
Lyondell Petrochemical G.P. Inc. and Lyondell Petrochemical L.P. Inc. ('Lyondell
LP'). Millennium also owns its interest in Equistar through two wholly owned
subsidiaries, Millennium Petrochemicals GP LLC and Millennium Petrochemicals LP
LLC ('Millennium LP').

    On May 15, 1998, Equistar was expanded with the contribution of certain
assets from Occidental Petroleum Corporation ('Occidental') (see Note 3). These
assets included the ethylene, propylene and ethylene oxide ('EO') and EO
derivatives businesses and certain pipeline assets held by Oxy Petrochemicals
Inc. ('Oxy Petrochemicals'), a former subsidiary of Occidental, a 50% interest
in a joint venture ('PD Glycol') between PDG Chemical Inc. and E.I. DuPont de
Nemours and Company, and a lease to Equistar of the Lake Charles, Louisiana
olefins plant and related pipelines held by Occidental Chemical Corporation
('Occidental Chemical') (collectively, 'Occidental Contributed Business').
Occidental Chemical and PDG Chemical Inc. are both 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 Equistar 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 Equistar for an aggregate partnership interest of 29.5%.
In addition, Equistar assumed approximately $205 million of Occidental
indebtedness and Equistar issued a promissory note to an Occidental subsidiary
in the amount of $420 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, Equistar 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,
Equistar and Occidental also entered into a long-term agreement for Equistar to
supply the ethylene requirements for Occidental Chemical's U.S. manufacturing
plants.

    Upon completion of this transaction, Equistar is now owned 41% by Lyondell,
29.5% by Millennium and 29.5% by Occidental, all through wholly owned
subsidiaries.

    Equistar owns and operates the petrochemicals and polymers businesses
contributed by Lyondell, Millennium and Occidental ('Contributed Businesses'),
which consist of 17 manufacturing facilities primarily on the U.S. Gulf Coast
and in the U.S. Midwest. The petrochemicals segment manufactures and markets
olefins, oxygenated products, aromatics and specialty products. Olefins include
ethylene, propylene and butadiene, and oxygenated products include ethylene
oxide, ethylene glycol, ethanol and methyl tertiary butyl ether ('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 insulating resins, and
polymeric

powders. The concentrates and compounds business, which was part of performance
polymers products, was sold effective April 30, 1999 (see Note 5).

    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 upon their percentage ownership of Equistar.
Distributions are made to the partners based upon their percentage ownership of
Equistar. Additional cash contributions required by the Partnership will also be
based upon the partners' percentage ownership of Equistar.

2. Summary of Significant Accounting Policies

    Basis of Presentation -- The consolidated financial statements include the
accounts of Equistar and its wholly owned subsidiaries. All significant
intercompany accounts and transactions have been eliminated in consolidation.

    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. Equistar's policy
is to invest cash in conservative, highly rated instruments and limit the amount
of credit exposure to any one institution. Equistar performs periodic
evaluations of the relative credit standing of these financial institutions
which are considered in Equistar's investment strategy.

    Equistar 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 Equistar's discretion. As a result, none of
Equistar's cash is restricted.

    Accounts Receivable -- Equistar sells its products primarily to companies in
the petrochemicals and polymers industries. Equistar 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 Consolidated Balance Sheets as
a reduction of accounts receivable, totaled $9 million and $6 million at
December 31, 2000 and 1999, respectively.

    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, Equistar removes the cost
of the assets and the related accumulated depreciation from the accounts and
reflects any resulting gains or losses in the Consolidated Statements of Income.
Equistar'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 major repairs and
maintenance incurred in connection with substantial overhauls or maintenance
turnarounds of production units at Equistar'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. Equistar
amortized $24 million, $25 million and $20 million of deferred turnaround
maintenance and repair costs for the years ended December 31, 2000, 1999 and
1998, respectively.

    Deferred Software Costs -- Costs to purchase and develop software for
internal use are deferred and amortized on a straight-line basis over a range of
3 to 10 years. Equistar amortized $13 million, $12

                                      F-13

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (Continued)

million and $6 million of deferred software costs for the years ended
December 31, 2000, 1999 and 1998, 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 40 years.
Accumulated amortization of goodwill was $232 million, $199 million and $166
million at December 31, 2000, 1999 and 1998, respectively.

    Investment in PD Glycol -- Equistar holds a 50% interest in a joint venture
with E.I. DuPont 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 using the equity method of accounting.
At December 31, 2000 and 1999, Equistar's underlying equity in the net assets of
PD Glycol exceeded the cost of the investment by $7 million and $8 million,
respectively. The excess is being accreted into income on a straight-line basis
over a period of 25 years.

    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 be reasonably estimated. The estimated
liabilities have not been discounted to present value. Environmental remediation
costs are expensed or capitalized in accordance with accounting principles
generally accepted in the United States of America.

    Exchanges -- Inventory 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 -- 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.

    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.

    Comprehensive Income -- Equistar had no items of other comprehensive income
during the years ended December 31, 2000, 1999 and 1998.

    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, Equistar reviews its long-lived assets, including goodwill, for impairment
on an exception basis whenever events or changes in circumstances indicate a
potential loss in utility. Impairment losses are recognized in 'Restructuring
and other unusual charges' in the Consolidated Statements of Income.

    Derivatives -- Adoption of SFAS No. 133, Accounting for Derivative
Instruments and Hedging Activities, did not have a significant impact on the
Consolidated Financial Statements of Equistar. The statement is effective for
Equistar's calendar year 2001.

    Reclassifications -- Certain previously reported amounts have been
reclassified to conform to classifications adopted in 2000.

3. Occidental Contributed Business

    On May 15, 1998, Equistar 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 Consolidated Statements of Income

                                      F-14

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (Continued)

prospectively from May 15, 1998. Occidental contributed assets and liabilities
to Equistar with a net fair value of $2.1 billion in exchange for a 29.5%
interest in the Partnership. Equistar 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 upon the estimated fair values of such assets and
liabilities at the date of the contribution. The fair value was determined based
upon a combination of internal valuations performed by Lyondell, Millennium and
Occidental using the income approach. The fair values of the assets contributed
and liabilities assumed by the Partnership on May 15, 1998 were as follows:

4. Related Party Transactions

    Product Transactions with Lyondell -- Lyondell has purchased benzene,
ethylene, propylene and other products at market-related prices from Equistar
since Lyondell's acquisition of ARCO Chemical Company in July 1998. Currently,
Equistar sells ethylene, propylene and benzene to Lyondell at market-related
prices pursuant to agreements dated effective as of August 1999. Under the
agreements, Lyondell is required to purchase 100% of its benzene, ethylene and
propylene requirements for its Channelview and Bayport, Texas facilities, with
the exception of quantities of one product that Lyondell is obligated to
purchase under a supply agreement with an unrelated third party entered into
prior to 1999 and expiring in 2015. The initial term of each of the agreements
between Equistar and Lyondell expires on December 31, 2014. After the initial
term, each of those agreements automatically renews for successive one-year
periods and either party may terminate any of the agreements on one year's
notice. The pricing terms under the agreements between Equistar and Lyondell are
similar to the pricing terms under the ethylene sales agreement between Equistar
and Occidental Chemical. In addition, a wholly owned subsidiary of Lyondell
licenses MTBE technology to Equistar. Lyondell also purchases a significant
portion of the MTBE produced by Equistar at one of its two Channelview units at
market-related prices. Sales to Lyondell totaled $572 million, $242 million and
$89 million for the years ended

                                      F-15

                             EQUISTAR CHEMICALS, LP
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (Continued)

December 31, 2000 and 1999 and for the period from August 1, 1998 to
December 31, 1998, respectively. Purchases from Lyondell totaled $2 million, $6
million and $2 million for the years ended December 31, 2000 and 1999 and for
the period from August 1, 1998 to December 31, 1998, respectively.

    Product Transactions with Occidental Chemical -- Equistar and Occidental
Chemical entered into a Sales Agreement, dated May 15, 1998 ('Ethylene Sales
Agreement'). Under the terms of the Ethylene Sales Agreement, Occidental
Chemical agreed to purchase an amount of ethylene from Equistar equal to 100% of
the ethylene feedstock requirements of Occidental Chemical's United States
plants less any quantities up to 250 million pounds tolled in accordance with
the provisions of such agreement. Upon three years notice from either party to
the other, Equistar'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 cannot decline to zero prior to
December 31, 2013 unless certain specified force majeure events occur. The
Ethylene Sales Agreement provides for sales of ethylene at market-related
prices. In addition to ethylene, Equistar sells methanol, ethers, and glycols to
Occidental Chemical. During the years ended December 31, 2000 and 1999 and the
period from May 15, 1998 to December 31, 1998, Equistar sold Occidental Chemical
$558 million, $435 million and $171 million, respectively, of product, primarily
under the Ethylene Sales Agreement.

    Equistar also purchases various products from Occidental Chemical. During
the years ended December 31, 2000 and 1999 and the period from May 15, 1998 to
December 31, 1998, purchases from Occidental Chemical totaled $2 million, $2
million and $4 million, respectively.

    Product Transactions with Millennium -- Equistar 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% of its ethylene requirements for its LaPorte, Texas
facility. The initial term of the contract expired December 1, 2000 and
thereafter, renews annually. Either party may terminate on one year's notice.
Neither party has provided notice of termination of the agreement. The pricing
terms of this agreement are similar to the pricing terms of the Ethylene Sales
Agreement with Occidental Chemical. Equistar sold Millennium $90 million, $54
million, and $41 million of ethylene in 2000, 1999 and 1998, respectively.

    Equistar purchases vinyl acetate monomer ('VAM') feedstock from Millennium
at formula-based market prices pursuant to an agreement entered into in
connection with the formation of Equistar. Under this agreement, Equistar is
required to purchase 100% of its VAM feedstock requirements for its LaPorte,
Texas, Clinton, Illinois, and Morris, Illinois plants for the production of
ethylene vinyl acetate products at those locations. The initial term of the
contract expires December 31, 2000 and thereafter, renews annually. Either party
may terminate on one year's notice of termination. The initial term will extend
until December 31, 2002 if Millennium elects to increase the amount of ethylene
purchased under the Ethylene Sales Agreement. Millennium did not elect to
increase the amount of ethylene purchased under the Ethylene Sales Agreement.
Therefore, the contract for VAM purchases expired December 31, 2000 and was
subsequently renewed for one year under the automatic renewal provisions. During
the years ending December 31, 2000, 1999 and 1998, purchases from Millennium,
primarily of vinyl acetate monomer, were $16 million, $12 million, and $14
million, respectively.

    Product Transactions with Oxy Vinyls, LP -- Occidental Chemical owns 76% of
Oxy Vinyls, LP ('Oxy Vinyls'), a joint venture company formed with an unrelated
third party effective May 1, 1999. Equistar sells ethylene to Oxy Vinyls for Oxy
Vinyls' LaPorte, Texas facility at market-related prices pursuant to an
agreement dated effective as of June 1998, which agreement was assigned to Oxy
Vinyls by one of its owners. The initial term of the agreement expires on
December 31, 2003. After the initial term, the agreement automatically renews
for successive one-year periods and either party may

terminate the agreement on 24 months' notice. Ethylene sales to Oxy Vinyls
totaled $67 million for the year ended December 31, 2000 and $93 million for the
period from May 1, 1999 to December 31, 1999.

    Transactions with LYONDELL-CITGO Refining LP -- 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 Equistar. Accordingly, certain olefins by-products
are sold to LCR for processing into gasoline and certain refinery products are
sold to Equistar as feedstocks. Sales of product to LCR were $425 million, $250
million and $223 million and purchases from LCR were $264 million, $190 million
and $131 million for the years ended December 31, 2000, 1999 and 1998,
respectively. Equistar also assumed certain processing arrangements as well as
storage obligations between Lyondell and LCR and provides certain marketing and
information processing services for LCR. Aggregate charges under these various
service agreements of $15 million, $13 million and $15 million were made to LCR
by Equistar for the years ended December 31, 2000, 1999 and 1998, respectively.
All of the agreements between LCR and Equistar are on terms generally
representative of prevailing market prices.

    Transactions with LMC -- Lyondell Methanol Company, L.P. ('LMC') sells all
of its products to Equistar. For the years ending December 31, 2000, 1999 and
1998, purchases from LMC were $165 million, $95 million and $103 million,
respectively. Equistar sells natural gas to LMC at prices generally
representative of its cost. Purchases by LMC of natural gas feedstock from
Equistar totaled $85 million, $46 million and $44 million for the years ended
December 31, 2000, 1999 and 1998, respectively. Equistar provides operating and
other services for LMC under the terms of existing agreements that were assumed
by Equistar from Lyondell, including the lease to LMC by Equistar of the real
property on which its methanol plant is located. Pursuant to the terms of those
agreements, LMC pays Equistar a management fee and reimburses certain expenses
of Equistar at cost. Management fees charged by Equistar to LMC totaled $6
million during each of the years ending December 31, 2000, 1999 and 1998.

    Shared Services Agreement with Lyondell -- During 1998 and 1999, Lyondell
provided certain administrative services to Equistar, including legal, risk
management, treasury, tax and employee benefit plan administrative services,
while Equistar provided services to Lyondell in the areas of health, safety and
environment, human resources, information technology and legal. In November
1999, Lyondell and Equistar announced an agreement to utilize shared services
more broadly, consolidating such services among Lyondell and Equistar. These
services included information technology, human resources, materials management,
raw material supply, customer supply chain, health, safety and environmental,
engineering, research and development, facility services, legal, accounting,
treasury, internal audit, and tax (the 'Shared Services Agreement'). Beginning
January 1, 2000, employee-related and indirect costs were allocated between the
two companies in the manner prescribed in the Shared Services Agreement, while
direct third party costs, incurred exclusively for either Lyondell or Equistar,
were charged directly to that entity. During the years ended December 31, 2000,
1999 and 1998, Lyondell charged Equistar $133 million, $9 million and $3 million
for these services. The increased charges to Equistar during 2000 resulted from
the increase in services provided by Lyondell under the Shared Services
Agreement. During the years ended December 31, 1999 and 1998, Equistar charged
Lyondell approximately $8 million and approximately $1 million, respectively,
for services. There were no billings from Equistar to Lyondell for the year
ended December 31, 2000.

    Shared Services and Shared-Site Agreements with Millennium -- Equistar and
Millennium have entered into a variety of operating, manufacturing and technical
service agreements related to the business of Equistar and the businesses
retained by Millennium Petrochemicals. These agreements include the provision by
Equistar to Millennium Petrochemicals of materials management, certain
utilities, administrative office space, and health and safety services. During
the years ended December 31, 2000, 1999 and 1998, Equistar charged Millennium
Petrochemicals $2 million, $3 million and $5 million for these services. These
agreements also include the provision by Millennium Petrochemicals to Equistar
of certain operational services, including barge dock access. During each of

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (Continued)

the years ended December 31, 2000, 1999 and 1998, Millennium Petrochemicals
charged Equistar less than $1 million for these services.

    Operating Agreement with Occidental Chemical -- On May 15, 1998, Occidental
Chemical and Equistar entered into an Operating Agreement ('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.
The Operating Agreement terminated on June 1, 1998. During the term of the
Operating Agreement, Equistar paid Occidental Chemical an administrative fee of
$1 million.

    Transition Services Agreement with Occidental Chemical -- 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 Equistar 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.
Predominantly all services under the Transition Services Agreement ceased in
June 1999 in accordance with the terms of the agreement. Health, safety, and
environmental services were extended until December 31, 1999 as permitted by the
Transition Services Agreement. During the year ended December 31, 1999 and the
period from June 1, 1998 to December 31, 1998, Equistar expensed $2 million and
$6 million, respectively, in connection with services provided pursuant to the
Transition Service Agreement.

    Loans to Millennium and Occidental -- In connection with Occidental's
admission into Equistar in May 1998, Equistar executed promissory notes to
Millennium and Occidental in the principal amounts of $75 million and $420
million, respectively. Each of the notes provided for the annual accrual of
interest at a rate equal to LIBOR plus 0.6%. 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 Equistar in the form of a $345 million
promissory note ('Lyondell Note'). The Lyondell Note bore interest at LIBOR plus
a market spread. The note was repaid in full by Lyondell in July 1998. Interest
income on the Lyondell Note totaled $13 million during 1998.

5. Sale of Concentrates and Compounds Business

    Effective April 30, 1999, Equistar completed the sale of its concentrates
and compounds business. The transaction included two manufacturing facilities,
located in Heath, Ohio and Crockett, Texas, and related inventories. Equistar's
proceeds from the sale were approximately $75 million.

6. Restructuring and Other Unusual Charges

    During the fourth quarter 1999, Equistar recorded a charge of $96 million
associated with decisions to shut down certain polymer reactors and to
consolidate certain administrative functions between Lyondell and Equistar. The
decision to shut down the reactors was based on their high production cost,
market conditions in the polyethylene industry and the flexibility to utilize
more efficient reactors to meet customer requirements. Accordingly, Equistar
recorded a charge of $72 million to adjust the asset carrying values. The
remaining $24 million of the total charge represents severance and other
employee-related costs for approximately 500 employee positions that are being
eliminated. The eliminated positions, primarily administrative functions,
resulted from opportunities to share such services between Lyondell and Equistar
and, to a lesser extent, positions associated with the shut down polymer
reactors. Through December 31, 2000, approximately $19 million of severance and
other employee-related costs had been paid and charged against the accrued
liability. As of December 31, 2000, substantially all of the employee
terminations had been completed and the remaining liability was eliminated.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (Continued)

    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.

7. Accounts Receivable

    In December 1998, Equistar entered into a purchase agreement with an
independent issuer of receivables-backed commercial paper. Under the terms of
the agreement, Equistar agreed to sell on an ongoing basis and without recourse,
designated accounts receivable. To maintain the balance of the accounts
receivable sold, Equistar is obligated to sell new receivables as existing
receivables are collected. The agreement continues until terminated upon notice
by either party.

    At December 31, 1998, 1999 and 2000, Equistar's gross accounts receivable
that had been sold to the purchasers aggregated $130 million. Increases and
decreases in the amount have been reported as operating cash flows in the
Consolidated Statements of Cash Flows. Costs related to the sale are included in
'Selling, general and administrative expenses' in the Consolidated Statements of
Income.

8. 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. Inventories at December 31, 2000 and 1999 consisted
of the following:

    No interest was capitalized during 2000, 1999 and 1998. Depreciation expense
for the years ending December 31, 2000, 1999 and 1998 was $229 million, $221
million and $200 million, respectively.

    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 upon Equistar's actual experience 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.

11. Pension and Other Postretirement Benefits

    All full-time regular employees of the Partnership are covered by defined
benefit pension plans sponsored by Equistar. The plans became effective January
1, 1998, except for union represented employees formerly employed by Millennium,
whose plans were contributed to Equistar on December 1, 1997, and union
represented employees formerly employed by Occidental, whose plans were
contributed to Equistar on May 15, 1998. In connection with the formation of
Equistar, there were no pension assets or obligations contributed to Equistar,
except for the union represented plans described above. Retirement benefits are
based upon years of service and the employee's highest three consecutive years
of compensation during the last ten years of service. Equistar accrues pension
costs based upon an actuarial valuation and funds the plans through periodic
contributions to pension trust funds as required by applicable law. Equistar
also has unfunded supplemental nonqualified retirement plans, which provide
pension benefits for certain employees in excess of the tax qualified plans'
limits. In addition, Equistar sponsors unfunded postretirement benefit plans
other than pensions for both salaried and nonsalaried employees, which provide
medical and life insurance benefits. These postretirement health care plans are
contributory while the life insurance plans are noncontributory.

    For measurement purposes, the assumed annual rate of increase in the per
capita cost of covered health care benefits as of December 31, 2000 was 7.0% for
2001 and 5.0% thereafter. The health care cost trend rate assumption does not
have a significant effect on the amounts reported. To illustrate, increasing or
decreasing the assumed health care cost trend rates by one percentage point in
each year would change the accumulated postretirement benefit liability as of
December 31, 2000 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.

    Equistar also maintains voluntary defined contribution savings plans for
eligible employees. Contributions to the plans by Equistar were $17 million, $20
million and $15 million for the years ended December 31, 2000, 1999 and 1998,
respectively.

12. Long-Term Debt and Financing Arrangements

    In February 1999, Equistar 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
new notes. The debt securities include $300 million of 8.50% Notes, which will
mature on February 15, 2004, and $600 million of 8.75% Notes, which will mature
on February 15, 2009. Equistar used the net proceeds from this offering (i) to
repay the $205 million outstanding under a capitalized lease obligation relating
to Equistar's Corpus Christi facility, (ii) to repay the outstanding balance
under the $500 million credit agreement, after which the $500 million credit
agreement was terminated, (iii) to repay the outstanding $150 million, 10.00%
Notes due in June 1999, and (iv) to the extent of the remaining net proceeds, to
reduce outstanding borrowing under the five-year credit facility and for
Partnership working capital purposes.

    Equistar has a five-year, $1.25 billion credit facility with a group of
banks expiring November 2002. Borrowing under the facility bears interest at
either the Federal Funds rate plus 1/2 of 1%, LIBOR plus 1/2 of 1%, 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 upon the type of
borrowing made under the facility. Borrowing under the facility had a weighted
average interest rate of 7.13% and 6.0% at December 31, 2000 and 1999,
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 31, 2004, Millennium America Inc. may elect to terminate the
guarantee if certain conditions are met including financial ratios and
covenants. In addition, Millennium America Inc. may elect to terminate the
guarantee if Millennium Petrochemicals Inc. sells its interests in Millennium GP
and Millennium LP or if those entities sell their interests in Equistar,
provided certain conditions are met including financial ratios and covenants.

    The credit facility is available for working capital and general Partnership
purposes as needed and contains covenants that, subject to exceptions, restrict
sale and leaseback transactions, lien incurrence, debt incurrence, sales of
assets and mergers and consolidations, and require Equistar to maintain
specified financial ratios, in all cases as provided in the credit facility. The
breach of these covenants could permit the lenders to declare the loans
immediately payable and to terminate future lending commitments.

    Equistar was in compliance with all covenants under its credit facility as
of December 31, 2000. However, given the poor current business environment,
Equistar is seeking an amendment to its credit facility that would increase its
financial and operating flexibility, primarily by making certain financial

ratio requirements less restrictive. Equistar anticipates that the amendment
will become effective prior to March 31, 2001.

    The terminated $500 million credit agreement was entered into on June 12,
1998. Borrowing under the agreement bore interest at either the Federal Funds
rate plus 1/2 of 1%, LIBOR plus 0.625%, a fixed rate offered by one of the
sponsoring banks or interest rates that were based on a competitive auction
feature.

    Long-term debt at December 31 consisted of the following:

medium-term notes mature at various dates from 2001 to 2005 and had a weighted
average interest rate of 9.6% and 10.0% at December 31, 2000 and 1999,
respectively.

    The medium-term Notes, the 9.125% Notes, the 6.5% Notes and the 7.55%
Debentures were assumed by Equistar from Lyondell when Equistar was formed in
1997. As between Equistar and Lyondell, Equistar is primarily liable for this
debt. Lyondell remains a co-obligor for the medium-term notes and certain events
involving only Lyondell could give rise to events of default under those notes,
permitting the obligations to be accelerated. If such an event permitted more
than $50 million of the medium-term notes to be accelerated, the lenders under
Equistar's $1.25 billion revolving credit facility would have the right to
accelerate all debt outstanding under the facility and to terminate future
lending commitments. $90 million aggregate principal amount of the medium-term
notes will mature on August 1, 2001. Under certain limited circumstances, the
holders of the medium-term notes have the right to require repurchase of the
notes. Following amendments to the indentures for the 9.125% Notes and 6.5%
Notes and the 7.55% Debentures in November 2000, Lyondell remains a guarantor of
that debt but not a co-obligor. The consolidated financial statements of
Lyondell are filed as an exhibit to Equistar's Annual Report on Form 10-K for
the year ended December 31, 2000.

13. Financial Instruments

    Equistar does not buy, sell, hold or issue financial instruments for
speculative trading purposes.

    Beginning October 1999, Equistar entered into over-the-counter 'derivatives'
and price collar agreements for crude oil with Occidental Energy Marketing,
Inc., a subsidiary of Occidental, to help manage its exposure to commodity price
risk with respect to crude-oil related raw material purchases. At December 31,
2000, 'derivatives' agreements covering 5.1 million barrels and maturing from
January 2001 through July 2001 were outstanding. The carrying value and fair
market value of these derivative instruments at December 31, 2000 represented a
liability of $13 million and was based on

                                      F-23

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (Continued)

quoted market prices. At December 31, 1999, 'derivatives' and collar agreements
covering 2.4 million and 1.5 million barrels, respectively, and maturing in
January 2000, were outstanding. Both the carrying value and fair market value of
these derivative instruments at December 31, 1999 represented an asset of $7
million and was based on quoted market prices. Unrealized gains and losses on
'derivatives' and price collars are deferred until realized at which time they
are reflected in the cost of the purchased raw material. See Item 7a. Disclosure
of Market and Regulatory Risk -- Commodity Price Risk.

    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 accrued liabilities, approximated
their carrying value due to their short maturity. Based on the borrowing rates
currently available to Equistar for debt with terms and average maturities
similar to Equistar's debt portfolio, the fair value of Equistar's long-term
debt, including amounts due within one year, was approximately $2.1 billion and
$2.2 billion at December 31, 2000 and 1999, respectively.

    Equistar had issued letters of credit totaling $1 million and $6 million at
December 31, 2000 and 1999, respectively.

14. Commitments and Contingencies

    Commitments -- Equistar 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. See
also Note 4, describing related party commitments.

    Equistar is party to various unconditional purchase obligation contracts as
a purchaser for product and services. At December 31, 2000, future minimum
payments under these contracts with noncancelable contract terms in excess of
one year were as follows:

</TABLE>

    Equistar's total purchases under these agreements were $35 million, $39
million and $35 million for the years ending December 31, 2000, 1999 and 1998,
respectively.

    Indemnification Arrangements -- 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 that are 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. As of December 31, 2000,
Equistar had incurred a total of $16 million for these uninsured claims and
liabilities. Equistar also agreed to assume third party claims that are related
to certain pre-closing contingent liabilities that are asserted for the first
time after December 1, 2004 for Lyondell and Millennium, and for the first time
after May 15, 2005 for Occidental.

    Environmental -- Equistar's policy is to be in compliance with all
applicable environmental laws. Equistar 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, Equistar
cannot accurately predict future developments, such as increasingly strict
requirements of environmental laws, inspection and enforcement policies and

                                      F-24

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (Continued)

compliance costs therefrom which might affect the handling, manufacture, use,
emission or disposal of products, other materials or hazardous and non-hazardous
waste. Equistar had no reserves for environmental matters as of December 31,
2000 and 1999.

    The eight-county Houston/Galveston region has been designated a severe
non-attainment area for ozone by the EPA. As a result, the Texas Natural
Resource Conservation Commission ('TNRCC') has submitted a plan to the EPA to
reach and demonstrate compliance with the ozone standard by the year 2007. These
emission reduction controls must be installed during the next several years,
well in advance of the 2007 deadline. This could result in increased capital
investment, which could be between $150 million and $300 million before the 2007
deadline, as well as higher annual operating costs for Equistar. Equistar has
been actively involved with a number of organizations to help solve the ozone
problem in the most cost-effective manner and, in January 2001, Equistar and an
organization composed of industry participants filed a lawsuit against the TNRCC
to encourage adoption of their alternative plan to achieve the same air quality
improvement with less negative economic impact on the region.

    In the United States, the Clean Air Act Amendments of 1990 set minimum
levels for oxygenates, such as MTBE, in gasoline sold in areas not meeting
specified air quality standards. However, while studies by federal and state
agencies and other organizations have shown that MTBE is safe for use in
gasoline, is not carcinogenic and is effective in reducing automotive emissions,
the presence of MTBE in some water supplies in California and other states due
to gasoline leaking from underground storage tanks and in surface water from
recreational water craft has led to public concern that MTBE may, in certain
limited circumstances, affect the taste and odor of drinking water supplies, and
thereby lead to possible environmental issues.

    Certain federal and state governmental initiatives have sought either to
rescind the oxygenate requirement for reformulated gasoline or to restrict or
ban the use of MTBE. Such actions, to be effective, would require (i) a waiver
of the state's oxygenate mandate, (ii) Congressional action in the form of an
amendment to the Clean Air Act or (iii) replacement of MTBE with another
oxygenate such as ethanol, a more costly, untested, and less widely available
additive. At the federal level, a blue ribbon panel appointed by the EPA issued
its report on July 27, 1999. That report recommended, among other things,
reducing the use of MTBE in gasoline. During 2000, the EPA announced its intent
to seek legislative changes from Congress to give the EPA authority to ban MTBE
over a three-year period. Such action would only be granted through amendments
to the Clean Air Act. Additionally, the EPA is seeking a ban of MTBE utilizing
rulemaking authority contained in the Toxic Substance Control Act. It would take
at least three years for such a rule to issue. Recently, however, senior policy
analysts at the U.S. Department of Energy presented a study stating that banning
MTBE would create significant economic risk. The presentation did not identify
any benefits from banning MTBE. The EPA initiatives mentioned above or other
governmental actions could result in a significant reduction in Equistar's MTBE
sales. Equistar has developed technologies to convert its process to produce
alternate gasoline blending components should it be necessary to reduce MTBE
production in the future.

    General -- 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 Equistar.

    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 Equistar. 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 Equistar'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.

    Operating lease net rental expense was $115 million, $112 million and $110
million for the years ending December 31, 2000, 1999 and 1998, respectively.

    Equistar leases railcars for the distribution of products in its polymers
business segment. The railcars are leased under two master leases entered into
in 1999 and a third master lease entered into in 1996 by Millennium and assumed
by Equistar upon its formation on December 1, 1997. The leases have five
renewable one-year terms and mature after the fifth year. Equistar may, at its
option, purchase the railcars during or at the end of the lease term for an
amount generally equal to the lessor's unrecovered costs, as defined. If
Equistar does not exercise the purchase option, the railcars will be sold and
Equistar will pay the lessor to the extent the proceeds from the sale of the
railcars are less than their guaranteed residual value, as defined by the
agreements. The guaranteed residual value under these leases was approximately
$185 million at December 31, 2000.

17. Segment Information and Related Information

    Using the guidelines set forth in SFAS No. 131, Disclosures about Segments
of an Enterprise and Related Information, Equistar has identified two reportable
segments in which it operates. The reportable segments are petrochemicals and
polymers. The petrochemicals segment includes olefins, oxygenated products,
aromatics and specialty products. Olefins include ethylene, propylene and
butadiene, and the oxygenated products include ethylene oxide, ethylene glycol,
ethanol and MTBE. Aromatics include 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 insulating resins, and polymeric powders. The
concentrates and compounds business, which was part of performance polymers, was
sold effective April 30, 1999 (see Note 5).

    No customer accounted for 10% or more of sales during the years ended
December 31, 2000, 1999 or 1998.

18. Subsequent Event

    Equistar discontinued production at its Port Arthur, Texas, polyethylene
facility on February 28, 2001 and shut down the facility. Closed production
units include a 240 million pounds per year HDPE reactor and an LDPE reactor
with annual capacity of 160 million pounds. These units and a 300 million pounds
per year HDPE reactor mothballed in 1999 have been shut down permanently. The
asset values of these production units were previously adjusted as part of a $96
million restructuring charge recognized in 1999. Equistar expects to incur
approximately $20 million of costs, including severance benefits for
approximately 125 people at the Port Arthur facility as well as shutdown-related
costs.
