MILLENNIUM

Overview of the Business

Millennium Chemicals Inc. (together with its consolidated
subsidiaries, Millennium) is a global chemical company, with total 2006 revenues of $1.9 billion, and assets of $2.4 billion as of December 31, 2006. On November 30, 2004, Lyondell Chemical Company
(Lyondell) acquired Millennium in a stock-for-stock business combination. As a result of the business combination, Millennium is now a wholly-owned subsidiary of Lyondell.

Millennium operates in two business segments: inorganic chemicals; and ethylene, co-products and derivatives.

Millenniums inorganic chemicals business segment primarily produces titanium
dioxide (TiO2). The inorganic chemicals business segment also produces titanium tetrachloride
(TiCl4), titanyl sulfate (TiOSO4), ultra-fine TiO2and other inorganic chemicals. On February 23, 2007, Millennium and The National Titanium Dioxide Company Ltd. (Cristal) signed an agreement for a proposed sale of Millenniums worldwide inorganic chemicals business to Cristal for $1.05
billion, in cash, plus the assumption of specified liabilities. The amount will be adjusted up or down depending on the change in value of net working capital, cash and specified indebtedness as of the closing date. Closing is anticipated to occur
in the first half of 2007.

Millenniums ethylene, co-products and derivatives business segment comprises its acetyls
business and its equity investment in Equistar Chemicals, LP (together with its consolidated subsidiaries, Equistar). Millenniums acetyls business produces vinyl acetate monomer (VAM), acetic acid and methanol, which is
a raw material for acetic acid. Equistar produces ethylene and its co-products, which primarily include propylene, butadiene and aromatics, which include benzene and toluene. Equistars derivatives primarily include polyethylene, ethylene oxide
(EO), ethylene glycol (EG) and other EO derivatives, as well as ethanol and polypropylene. Equistar also produces fuel products, such as methyl tertiary butyl ether (MTBE) and alkylate. Millennium owns 29.5% of
Equistar, the balance of which is owned by Lyondell through other subsidiaries. Millennium accounts for its interest in Equistar using the equity method.

Millennium also produces fragrance and flavor chemicals. For additional segment information and for geographic information for each of the years in the three-year period ended December 31, 2006, see Note 21 to

INORGANIC CHEMICALS SEGMENT

Overview

TiO2is the primary product of the inorganic chemicals business, which accounted for approximately 64% of Millenniums total
revenues in 2006, 65% in 2005 and 71% in 2004. TiO2is a white pigment used for imparting whiteness, brightness,
opacity and durability in a wide range of products, including paint and coatings, plastics, paper and elastomers. On February 23, 2007, Millennium and Cristal signed an agreement for a proposed sale of Millenniums worldwide inorganic chemicals
business to Cristal for $1.05 billion, in cash, plus the assumption of specified liabilities. Closing is anticipated to occur in the first half of 2007. The transaction would allow Millennium to accelerate debt repayment.

As of December 31, 2006, Millenniums annual TiO2production capacity, using the chloride process and the sulfate process discussed below, was approximately 670,000 metric tons.
Unless otherwise specified, annual processing capacities were calculated by estimating the average number of days in a typical year that a production unit of a plant is expected to operate, after allowing downtime for regular maintenance, and
multiplying that number by an amount equal to the units optimal daily output. Because the processing capacity of a production unit is an estimated amount, actual production volumes may be more or less than capacities set forth below.



|                        |  |                     |  |                       |  
|----------------------- |  | ------------------- |  | --------------------- | -
|TiO2 Production Process |  | Annual Capacity     |  | Percentageof Capacity |  
|Chloride Process        |  | 515,000 metric tons |  | 77                    | %
|Sulfate Process         |  | 155,000 metric tons |  | 23                    | %
|                        |  |                     |  |                       |  
|Total                   |  | 670,000 metric tons |  | 100                   | %

TiO2is produced in two crystalline forms: rutile and anatase. Rutile TiO2is primarily used in paint and coatings, ink and plastics. Anatase TiO2is primarily used in paper, ceramics, rubber and man-made fibers.

TiO2is manufactured using two different technologies. The
newer chloride process is a high-temperature process in which chlorine is used to produce an intermediate TiO2rutile crystal pigment, with greater purity and better control over the size distribution of the pigment particles than the alternative sulfate process permits. In general, the chloride process is also less intensive than the sulfate process in
terms of labor and energy. Because much of the chlorine can be recycled, the chloride process produces less waste than the sulfate process.

The sulfate process is a wet chemical process that uses concentrated sulfuric acid
to produce either an intermediate TiO2anatase or rutile crystal pigment. The sulfate process generates higher
volumes of waste, including iron sulfate and spent sulfuric acid.

Millenniums TiO2plants are located in the four major world markets for TiO2: North America, South America, Western Europe and the Asia/Pacific region. The North American plants, consisting of one in
Baltimore, Maryland and two in Ashtabula, Ohio, use the chloride process. The plant in Salvador, Bahia, Brazil uses the sulfate process. The Stallingborough, United Kingdom plant uses the chloride process. The plants in France at Le Havre, Normandy
and Thann, Alsace use the sulfate process. The Kemerton plant in Western Australia uses the chloride process.

Millennium also owns a mineral sands mine located at Mataraca, Paraiba, Brazil, which supplies the Brazilian plant with most of its titanium ores. As of December 31, 2006, the mine had
approximately 1.4 million metric tons of recoverable ilmenite reserves, approximately 233,000 metric tons of zircon reserves and approximately 21,000 metric tons of natural rutile reserves. The mine produced approximately 111,000 metric
tons of ilmenite, a titanium-bearing ore, in 2006. Approximately 99,000 metric tons of ilmenite produced at the mine were processed by the Salvador TiO2plant in 2006, while approximately 22,000 metric tons were sold to the plant in Le Havre, France and approximately 1,000 metric tons were sold to unrelated parties. The mine also produced
approximately 21,000 metric tons of zircon and approximately 2,000 metric tons of natural rutile titanium ore, all of which were sold to unrelated parties.

Millenniums inorganic
chemicals business also produces a number of specialty and performance products, some of which are manufactured at dedicated facilities and others of which are manufactured at facilities that also produce TiO2products. These products include titanium tetrachloride (TiCl4), titanyl sulfate (TiOSO4), ultra-fine TiO2and other inorganic chemicals.

Marketing and Sales

Of the
TiO2sold by Millennium in 2006, approximately 65% was sold to customers in the paint and coatings industry,
approximately 24% to customers in the plastics industry, approximately 10% to customers in the paper industry, and approximately 1% to other customers. Millennium experiences some seasonality in its TiO2sales because, in general, its customers production of paint and coatings are greatest in the spring and summer months. TiO2generally is sold by Millennium at prices determined by market-based negotiation under annual and multi-year contracts.TiO2is sold either directly to customers or, to a lesser extent, through agents or distributors, and is
distributed by rail, truck and ocean carrier in either dry or slurry form.

No single inorganic chemicals customer
accounted for 10% or more of Millenniums total revenues in 2006. For geographic data, see Note 21 to the Consolidated Financial Statements.

Raw Materials

Naturally occurring
titanium-bearing ores such as ilmenite and natural rutile occur as sand or hard rock deposits in various parts of the world and are used as raw materials in the TiO2extraction process. Mining companies are increasingly treating ilmenite to extract iron and other minerals to produce slag or synthetic rutile with higher TiO2concentrations, resulting in lower amounts of wastes and by-products during processing by TiO2pigment plants. Generally, titanium-bearing ores are shipped by using bulk carriers from terminals in the country of origin to TiO2production plants, usually located near port facilities. Millennium obtains ores from a number of suppliers in South Africa,
Australia, Canada, Brazil and Norway, generally pursuant to multi-year supply contracts. Rio Tinto Iron & Titanium Inc. (through its affiliates Richards Bay Iron & Titanium (Proprietary) Limited and QIT-Fer et Titane Inc.) and
Iluka Resources Limited are the worlds largest producers of titanium ores and they accounted for approximately 65% of the titanium ores purchased for Millenniums inorganic chemicals business in 2006.

Other major raw materials and supplies used in the production of TiO2are coke, chlorine, caustic soda, aluminum, sodium silicate, sodium aluminate, sulfuric acid, oxygen, nitrogen and natural gas.
The number of sources for and availability of these materials is specific to the particular geographic region in which a facility is located. There are certain risks related to the acquisition of raw materials from less-developed or developing
countries. See Item 1A. Risk FactorsRisks Relating to the BusinessesMillenniums international operations are subject to exchange rate fluctuations, exchange controls, political risks and other risks relating to non-U.S.
operations.

A number of the raw materials used by Millenniums inorganic chemicals business are provided by
only a few vendors and, accordingly, if one significant supplier or a number of significant suppliers were unable to meet their obligations under present supply arrangements, Millennium could suffer reduced supplies and/or be forced to incur
increased costs for these raw materials. For example, for the Australian plant, chlorine and caustic soda are obtained exclusively from one supplier under a long-term supply agreement. See Item 1A. Risk FactorsRisks Relating to the
BusinessesCosts of raw materials and energy, as well as reliability of supply, may result in increased operating expenses and reduced results of operations. However, at the present time, chloride- and sulfate-process raw materials are
available in sufficient quantities.

Competition and Industry Conditions

The bases for competition in the inorganic chemicals businesses are price, product quality, product performance, product delivery, customer service and reliability of supply.The major competitors for sales of TiO2are E. I. du Pont de Nemours and Company (DuPont), Huntsman Tioxide (Huntsman Tioxide, a business unit
of Huntsman Corporation), Kronos Worldwide, Inc. (Kronos) and Tronox Incorporated (Tronox, formerly a business unit of Kerr-McGee Corporation). Millennium estimates that collectively, as of December 31, 2006, DuPont,
Millennium, Huntsman Tioxide, Kronos and Tronox accounted for approximately 64% of the worlds TiO2

production capacity. Millennium is the second largest producer of TiO2in the world, based on published rated capacity.

In certain applications, TiO2competes with other whitening agents that are
generally less effective but less expensive. These alternate products include kaolin clays, calcium carbonate pigments and synthetic polymers materials.

Sulfate-process plants can be less competitive than chloride-process plants,
unless the sulfate-process plants (1) use lower cost raw materials and cost-effectively dispose of the waste, (2) have low labor costs, or (3) have higher selling prices through either tariff protection or specialty market position
for some portion of the plants output. When the TiO2industry is oversupplied, customers prefer the newer
chloride-process products and, thus, sulfate-process plants would operate at lower utilization rates than chloride-process plants.

Generally, new plant capacity additions in the TiO2industry are slow to develop because of the substantial capital expenditure required and the significant lead time (three to
five years typically for a new plant) needed for planning, obtaining environmental approvals and permits, construction of manufacturing facilities and arranging for raw material supplies. DuPont has announced plans to construct a 200,000 ton per
year TiO2plant in Dongying, China with planned completion in 2010. Debottlenecking and other capacity expansions at
existing plants require substantially less time and capital and can also increase overall industry capacity. For example, Huntsman Tioxide has announced plans to expand its TiO2facility in Greatham, U.K. by 50,000 tons.

ETHYLENE, CO-PRODUCTS AND DERIVATIVES SEGMENT

Millenniums ethylene, co-products and
derivatives segment comprises its acetyls business and its equity investment in Equistar.

Acetyls Business

Overview

The acetyls business includes VAM, acetic acid and methanol, which is a raw material
for acetic acid. VAM and acetic acid are manufactured by Millennium at facilities in La Porte, Texas. Millennium also owns an 85% interest in La Porte Methanol Company, which produces methanol at a plant in La Porte, Texas.The remaining 15%
interest is owned by Linde AG (Linde).

The following table outlines:

Unless otherwise specified, annual processing capacity was calculated by estimating the average 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 design raw material mix. Because the processing capacity of a production unit is an estimated amount, actual production
volumes may be more or less than the capacities set forth below. Capacities shown include 100% of the capacity of joint venture facilities.

|--- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Marketing and Sales

Sales of VAM accounted for approximately 15% of Millenniums total
revenues in 2006, and approximately 16% in 2005 and 2004. Sales of acetyls collectively accounted for approximately 25% of Millenniums total revenues in 2006, 26% in 2005 and 24% in 2004.

VAM is sold into domestic and export markets under multi-year contracts, and also on a spot basis. Acetic acid that is not consumed
internally for the production of VAM is sold into domestic and export markets under multi-year contracts, and also on a spot basis. Contract pricing for sales of VAM and acetic acid generally is determined by market-based negotiation, market index
or cost-based formulas. Millennium also sells VAM to Equistar and acetic acid to both Lyondell and Equistar at market-based pricing. Pursuant to an agreement that expired on December 31, 2006, a portion of the acetic acid produced at
Millenniums La Porte, Texas plant previously was converted into VAM through DuPonts nearby VAM plant and Millennium acquired all of the VAM production at DuPonts plant that was not utilized internally by DuPont. As of
January 1, 2007, Millennium produces those VAM volumes internally at its facilities. VAM and acetic acid are shipped by barge, ocean-going vessel, pipeline, tank car and tank truck. Millennium has bulk storage arrangements in Europe and South
America to better serve its customers requirements in those regions. Sales are made through a direct sales force, agents and distributors.

The La Porte, Texas methanol facility is owned by La Porte Methanol Company, Millenniums 85%-owned joint venture with Linde. Each party to the joint venture receives its respective share of the methanol
production. Millennium uses the methanol as a raw material for acetic acid and also sells the methanol under annual contracts and on a spot basis to large domestic customers. The product is shipped by barge and pipeline.

No single acetyls customer accounted for 10% or more of Millenniums total revenues in 2006. For geographic data, see Note 21 to the
Consolidated Financial Statements.

Raw Materials

The primary raw materials for the production of VAM are acetic acid and
ethylene. For VAM produced by Millennium, Millennium obtains its entire requirements for acetic acid from its internal production and buys all of its ethylene requirements from Equistar under a long-term supply contract based on market prices. In
2006, Millennium used a large percentage of its acetic acid production to produce VAM.

The primary raw materials required
for the production of acetic acid are carbon monoxide and methanol. Millennium purchases its carbon monoxide from Linde pursuant to a long-term contract under which pricing is based primarily on cost of production. La Porte Methanol Company,
Millenniums 85%-owned joint venture, supplies all of Millenniums requirements for methanol production. Natural gas is the primary raw material required for the production of methanol and carbon monoxide.

Competition and Industry Conditions

The bases for competition in the acetyls businesses are
price, product performance, product quality, product delivery, reliability of supply and customer service. The acetyls businesses compete globally with other large marketers and producers for sales of acetyls, including BP p.l.c., Celanese
Corporation (Celanese), The Dow Chemical Company (Dow), Eastman Chemical Company, Methanex Corporation and Saudi Basic Industries Corp. Millennium is the second largest producer of VAM and acetic acid in North America, the
third largest producer of acetic acid worldwide and the fourth largest producer of VAM worldwide, based on 2006 published rated production capacity.

Equity Investment in Equistar

Millennium owns a 29.5% interest in Equistar, a joint
venture with Lyondell. Millennium accounts for its interest in Equistar as an equity investment. Equistar reports its results of operations in one segment: ethylene, co-products and derivatives.

Overview

Equistar produces ethylene, co-products and derivatives at fifteen facilities
located in five states in the U.S. Ethylene co-products primarily include propylene, butadiene and aromatics, which include benzene and toluene. Derivatives primarily include polyethylene, EO, EG and other EO derivatives, as well as ethanol and
polypropylene. Equistar also produces fuel products, such as MTBE and alkylate. Ethylene is the most significant petrochemical in terms of worldwide production volume and is the key building block for polyethylene and a large number of other
chemicals, plastics and synthetics. Ethylene, co-products and derivatives are fundamental to many segments of the economy, including the production of consumer products, packaging, housing and automotive components and other durable and nondurable
goods.

Marketing and Sales

Equistar produces ethylene at six sites located in three states. Ethylene
produced by Equistar generally is consumed internally as a raw material in the production of derivatives, or is shipped by pipeline to customers. For the year ended December 31, 2006, approximately 87% of Equistars ethylene, based on
sales dollars, was used by Equistars derivatives facilities or sold to related parties at market-related prices. The sales to related parties during 2006 include significant ethylene sales to Occidental Chemical Corporation pursuant to a
long-term ethylene supply agreement. Occidental Chemical Corporation is a subsidiary of Occidental Petroleum Corporation (together with its subsidiaries and affiliates, collectively, Occidental), which owned 8.5% of Lyondells
outstanding common stock as of December 31, 2006 and after giving effect to Occidentals January 26, 2007 exercise of its warrant to purchase Lyondell common stock.Sales of ethylene accounted for approximately 12% of
Equistars total revenues in 2006, 13% in 2005 and 12% in 2004.

Ethylene co-products are manufactured by Equistar
primarily at four facilities in Texas. The Morris, Illinois and Clinton, Iowa facilities also can produce propylene.

Equistar consumes propylene in the production of polypropylene and also sells propylene to Lyondell at market-related prices. Equistars propylene production that is not consumed internally or sold to related parties generally is sold
under multi-year contracts. In addition, pursuant to a 15-year propylene supply arrangement entered into in 2003 with a subsidiary of Sunoco, Inc. (Sunoco), Equistar supplies 700 million pounds of propylene annually to Sunoco. Under
the arrangement, a majority of the propylene is supplied under a cost-based formula and the balance is supplied on a market-related basis. Sales of propylene accounted for approximately 20% of Equistars total revenues in 2006 and approximately
18% in 2005 and 2004.

Equistar generally sells its butadiene under multi-year contracts. Equistar sells benzene and
toluene to Lyondell at market-related prices. Most of Equistars benzene and toluene production that is not sold to related parties generally is sold under multi-year contracts. Equistar also sells benzene produced by Lyondell, which it
purchases from Lyondell at market-related prices. Sales of benzene accounted for less than 10% of Equistars total revenues in 2006 and 2005 and approximately 10% in 2004. Equistar serves as Lyondells sole agent to market toluene,
paraxylene and orthoxylene produced by Lyondell and receives a marketing fee for such services.

Equistar at times
purchases ethylene, propylene, benzene and butadiene for resale, when necessary, to satisfy customer demand for these products above production levels. Volumes of ethylene, propylene, benzene and butadiene purchased for resale can vary significantly
from period to period. However, purchased volumes generally do not have a significant impact on profitability.

MTBE
produced at one of the two Channelview units and at the Chocolate Bayou plant is sold to Lyondell at market-related prices. MTBE is produced for Lyondell at the second Channelview unit for a processing fee. Equistar produces alkylate for and returns
alkylate to Lyondell for a processing fee, and also sells alkylate both under short-term contracts and on a spot basis.

Most of the ethylene and propylene production of the Channelview, Chocolate Bayou, Corpus Christi and La Porte facilities is shipped via a pipeline system which has connections to numerous U.S. Gulf Coast consumers. This pipeline system,
some of which is owned and some of which is leased, extends from Corpus Christi to Mont Belvieu to Port Arthur, Texas as well as around the Lake Charles, Louisiana area. In addition, exchange agreements

with other ethylene and co-products producers allow access to customers who are not directly connected to Equistars pipeline system. Some ethylene is
shipped by railcar from Clinton, Iowa to Morris, Illinois and also to customers. A pipeline owned and operated by an unrelated party is used to transport ethylene from Morris, Illinois to Tuscola, Illinois. Some propylene is shipped by ocean-going
vessel. Butadiene, benzene, toluene and other products are distributed by pipeline, railcar, truck, barge or ocean-going vessel.

Polyethylene is manufactured by Equistar using a variety of technologies at five facilities in Texas and at the Morris, Illinois and Clinton, Iowa facilities. Polyethylene includes high density polyethylene (HDPE), low density
polyethylene (LDPE) and linear low density polyethylene (LLDPE). HDPE accounted for approximately 12% of Equistars total revenues in 2006 and 2005 and 14% in 2004, and polyethylene (HDPE, LDPE and LLDPE collectively)
accounted for approximately 21% of Equistars total revenues in 2006 and 2005 and 26% in 2004.

Polyethylene products
primarily are sold to an extensive base of established customers. Approximately two-thirds of Equistars domestic polyethylene product volumes are sold to customers under annual or multi-year contracts. The remainder of the polyethylene volume
generally is sold under customary terms and conditions without formal contracts. In either case, in most of the continuous supply relationships, prices are subject to change upon mutual agreement. Equistar also produces performance polymer products,
which include enhanced grades of polyethylene and polypropylene. Equistar believes 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.

EO or EO equivalents, and EOs primary derivative, EG, are produced at the
Bayport facility located in Pasadena, Texas and through a 50/50 joint venture between Equistar and DuPont in Beaumont, Texas. The Bayport facility also produces other derivatives of EO, principally ethylene glycol ethers and ethanolamines. EO and EG
typically are sold under multi-year contracts, with market-based pricing. Glycol ethers, ethanolamines and brake fluids are sold primarily into the solvent and distributor markets at market prices. Ethanol and ethers primarily are sold under
contracts at market prices. EO is shipped by railcar, and its derivatives are shipped by railcar, truck, isotank or ocean-going vessel.

Other derivatives products are primarily distributed by railcar. The vast majority of the derivatives products are sold in North America, primarily through Equistars sales organization. Sales agents are
generally engaged to market the derivatives products in the rest of the world.

Other than Lyondell, which accounted for
approximately 11% of Equistars total revenues in 2006, no single customer accounted for 10% or more of Equistars total revenues in 2006. For geographic data, see Note 21 to the Consolidated Financial Statements.

Raw Materials

Raw material cost is the largest component of the total cost for the production
of ethylene and co-products. The primary raw materials used are heavy liquids and natural gas liquids (NGLs). Heavy liquids include crude oil-based naphtha and gas oil, as well as condensate, a very light crude oil resulting from natural
gas production (collectively referred to as heavy liquids). NGLs include ethane, propane and butane. The use of heavy liquid raw materials results in the production of a significant amount of co-products such as propylene, butadiene,
benzene and toluene, as well as gasoline blending components, while the use of NGLs results in the production of a smaller amount of co-products, such as propylene.

The flexibility to consume a wide range of raw materials, including heavy liquids, has historically provided plants with that flexibility with an advantage over plants that are restricted in
their raw material processing capability to NGLs such as ethane and propane, assuming the co-products were recovered and sold. Facilities using heavy liquids historically have generated, on average, approximately four cents of additional variable
margin per pound of ethylene produced compared to facilities restricted to using ethane. This margin advantage is based on an average of historical data over a period of years and is subject to short-term fluctuations, which can be significant. For
example, the advantage during first quarter 2006 was well below the historical average. However, strengthening market conditions increased the advantage significantly for the remainder of the year. As a result, the advantage for

the full year 2006 was above the historical average. Equistar has the capability to realize this margin advantage due to its ability to process heavy liquids
at its Channelview, Corpus Christi and Chocolate Bayou ethylene and co-products facilities. Equistars Channelview and Corpus Christi facilities have the greatest operational flexibility among Equistars facilities to process significant
quantities of either heavy liquids or NGLs, depending upon the relative economic advantage of the alternative raw materials.

As described above, management believes that this raw material flexibility is a key advantage in the production of ethylene and co-products. As a result, Equistars heavy liquids requirements are sourced globally via a mix of
contractual and spot arrangements. Spot market purchases are made in order to maintain raw material flexibility and to take advantage of raw material pricing opportunities. A large portion of Equistars NGLs requirements are purchased via
contractual arrangements from a variety of sources, but NGLs also are purchased on the spot market. Equistar also obtains a portion of its heavy liquids requirements from Lyondells refinery at market-related prices. Heavy liquids generally are
delivered by ship or barge, and NGLs generally are delivered via pipeline.

Equistar purchases all of its methanol
requirements for ethylene and co-products from Lyondell at market-based prices. Also, Equistar purchases large amounts of natural gas to be used as energy for consumption in its business via market-based contractual arrangements with a variety of
sources.

The primary raw material for the derivatives products is ethylene. Equistars derivatives facilities
generally can receive their ethylene directly from Equistars ethylene and co-products facilities via its pipeline system, pipelines owned by unrelated parties or on-site production. Substantially all of the ethylene used in Equistars
polyethylene production is produced internally by Equistars ethylene and co-products facilities. However, the polyethylene plants at Chocolate Bayou, La Porte and Bayport, Texas are connected by pipeline to unrelated parties and could receive
ethylene via exchanges or purchases. The polypropylene facility at Morris, Illinois receives propylene from Equistars ethylene and co-products facilities, as well as unrelated parties.

The raw materials for ethylene, co-products and derivatives are, in general, commodity chemicals with numerous bulk suppliers and ready
availability at competitive prices. Historically, raw material availability for ethylene, co-products and derivatives has not been an issue. For additional discussion regarding the effects of raw material pricing and supply on recent operating
results, see Item 1A. Risk FactorsRisks Relating to the BusinessesCosts of raw materials and energy, as well as reliability of supply, may result in increased operating expenses and reduced results of operations and
Item 7. Managements Discussion and Analysis of Financial Condition and Results of Operations.

Competition and Industry Conditions

Competition in the ethylene, co-products and derivatives
businesses is based on price, product quality, product delivery, reliability of supply, product performance and customer service. Industry consolidation has brought North American production capacity under the control of fewer, although larger,
competitors.

Profitability is affected not only by supply and demand for ethylene, co-products and derivatives, but also
by raw material costs and price competition among producers, which may intensify due to, among other things, the addition of new capacity. In general, demand is a function of economic growth in the United States and elsewhere in the world, which
fluctuates. It is not possible to accurately predict the changes in raw material costs, market conditions, capacity utilization and other factors that will affect industry profitability in the future. In 2005, temporary hurricane-related shutdowns
greatly impacted supply and demand during the last four months of 2005, and significant U.S. production outages carried over into the first quarter of 2006. During the next five years, forecasts for the worldwide average annual ethylene capacity
additions are projected at more than 5%, with more than 80% of these additions in the Middle East and Northeast Asia. The average worldwide demand growth is expected to lag this rate only by approximately 1%. In the U.S., relatively stable ethylene
supply combined with sustained demand levels are projected to result in continued high average operating rates through 2008. Capacity share figures for Equistar and its competitors, discussed below, are based on completed production facilities and,
where appropriate, include the full capacity of joint venture facilities and certain long-term supply arrangements.

Equistar competes with other large domestic marketers and producers for sales of ethylene
and co-products, including Chevron Phillips Chemical Company LP (ChevronPhillips), Enterprise Products Partners L.P., Exxon Mobil Corporation (ExxonMobil), Huntsman Corporation (Huntsman), Ineos and Shell Chemical
Company. Equistars ethylene rated capacity at December 31, 2006 was approximately 10.8 billion pounds per year, or approximately 14% of total North American ethylene production capacity. Based on published rated production
capacities, Equistar is the second largest producer of ethylene in North America. North American ethylene rated capacity at December 31, 2006 was approximately 77 billion pounds per year, with approximately 77% of that North American
capacity located along the Gulf Coast.

Equistar competes with other large marketers and producers for sales of
derivatives, including Celanese, ChevronPhillips, Dow, Eastman Chemical Company, ExxonMobil, Formosa Plastics Corporation, Huntsman, Ineos, NOVA Chemicals Corporation, TOTAL and Westlake Polymers. Based on published rated industry capacities,
Equistar is the third largest producer of polyethylene in North America. The rated capacity of Equistars polyethylene units as of December 31, 2006 was approximately 5.8 billion pounds per year, or approximately 14% of total industry
capacity in North America. There are many other North American producers of polyethylene, the most significant of which are ChevronPhillips, Dow and ExxonMobil.

OTHER

Millennium also produces fragrance and flavors chemicals. The Brunswick, Georgia and
Jacksonville, Florida facilities manufacture terpene-based fragrance ingredients and flavor ingredients, primarily for the oral care markets. These products are also used in a number of other applications, including chemical reaction agents, or
initiators, for the rubber industry and solvents and cleaners, such as pine oil, for the hard surface cleaner markets.

ENVIRONMENTAL CAPITAL EXPENDITURES

Millennium and its joint ventures (together with the industries in which they operate) are subject to extensive national, state and local environmental laws and regulations concerning, and are required to have permits and licenses
regulating, emissions to the air, discharges onto land or waters and the generation, handling, storage, transportation, treatment and disposal of waste materials. In some cases, compliance with environmental, health and safety laws and regulations
can only be achieved by capital expenditures. In the years ended December 31, 2006, 2005 and 2004, Millennium spent approximately $5 million, $8 million and $8 million, respectively, for environmentally related capital
expenditures at existing facilities. Millennium currently estimates that environmentally related capital expenditures at its facilities will be approximately $10 million for 2007 and $15 million for 2008, reflecting the addition of a new
waste disposal landfill and fume containment equipment at a TiO2plant.

In the years ended December 31, 2006, 2005 and 2004, Equistar spent approximately $60 million, $62 million and $44 million,
respectively, for environmentally related capital expenditures at existing facilities. Equistar currently estimates that environmentally related capital expenditures at its facilities will be approximately $30 million for 2007 and
$15 million for 2008. Capital expenditures during 2005 and 2006 included significant expenditures for projects related to air emission reduction and wastewater management. The decreasing levels of estimated environmentally related capital
expenditures for 2007 and 2008 reflect the completion or near completion of these projects.

For additional information
regarding environmentally related capital expenditures, see Item 7. Managements Discussion and Analysis of Financial Condition and Results of OperationsEnvironmental Matters.

|Item 1A. | Risk Factors
|-------- | ------------

There are many factors that may affect the businesses and results of operations of Millennium and its joint ventures. For additional discussion regarding factors that may affect the businesses and operating results
of Millennium and its joint ventures, see Item 1. Business, Item 3. Legal Proceedings, Forward-Looking Statements, Item 7. Managements Discussion and Analysis of Financial Condition and Results of
Operations and Item 7A. Disclosure of Market Risk. If one or more of these risks actually occur, Millenniums business, financial position or results of operations could be materially and adversely affected.

Risks Relating to the Businesses

Costs of raw materials and energy, as well as
reliability of supply, may result in increased operating expenses and reduced results of operations.

Millennium and its joint ventures purchase large amounts of raw materials and energy for their businesses. The cost of these raw materials and energy, in the aggregate, represents a substantial
portion of their operating expenses. The costs of raw materials and energy used for acetyls and Equistars products, and the energy costs for TiO2, generally follow price trends of, and vary with the market conditions for, crude oil and natural gas, which may be highly volatile and cyclical. The costs of energy and certain raw materials remain
at high levels. There have been in the past, and will likely be in the future, periods of time when Millennium and its joint ventures are unable to pass raw material and energy cost increases on to customers quickly enough to avoid adverse impacts
on their results of operations. Customer consolidation also has made it more difficult to pass along cost increases to customers. The results of operations of Millennium and its joint ventures have been, and could be in the future, significantly
affected by increases and volatility in these costs. Cost increases also may increase working capital needs, which could reduce liquidity and cash flow for Millennium and its joint ventures. In addition, when raw material and energy costs increase
rapidly and are passed along to customers as product price increases, the credit risks associated with certain customers can be compounded. To the extent Millennium and its joint ventures increase their product sales prices to reflect rising raw
material and energy costs, demand for products may decrease as customers reduce their consumption or use substitute products, which may have an adverse impact on Millenniums or its joint ventures results of operations. See
Millennium and its joint ventures sell commodity products in highly competitive global markets and face significant price pressures below.

In addition, higher North American and European natural gas prices relative to natural gas cost-advantaged regions, such as the Middle East, have diminished the ability of many chemical producers to compete
internationally since natural gas prices affect a significant portion of the industrys raw materials and energy sources. This environment has in the past caused and may in the future cause a reduction in Millenniums or Equistars
exports, and has in the past reduced and may in the future reduce the competitiveness of U.S. and European producers. It also has in the past increased the competition for sales of chemicals within North America and Europe, as production that would
otherwise have been sold in other geographic regions was instead offered for sale in these regions, resulting in excess supply and lower margins in North America and Europe, and may do so in the future.

Furthermore, for Millennium and its joint ventures, there are a limited number of suppliers for some of their raw materials and utilities
and, in some cases, the number of sources for and availability of raw materials is specific to the particular geographic region in which a facility is located. In addition, for some products of Millennium and its joint ventures, the facilities
and/or distribution channels of raw material suppliers and Millennium and its joint ventures form an integrated system. This is especially true in the U.S. Gulf Coast where the infrastructure of the chemical and refining industries is tightly
integrated such that a major disruption of supply of a given commodity can negatively affect numerous participants, including suppliers of other raw materials. If one or more of Millenniums or its joint ventures significant suppliers
were unable to meet its obligations under present supply arrangements or supplies are otherwise disrupted, Millenniums or its joint ventures businesses could suffer reduced supplies or be forced to incur increased costs for their raw
materials, which would have a direct negative impact on plant operations. For example, Hurricanes Katrina and Rita negatively affected crude oil and natural gas supplies, as well as supplies of some of Millenniums and its joint ventures
other raw materials, contributing to increases in raw material prices during the second half of 2005 and, in some cases, disrupting production. In addition, hurricane-related disruption of rail and pipeline traffic in the U.S. Gulf Coast area
negatively affected shipments of raw materials and product.

The cyclicality and volatility of the chemical industry
may cause significant fluctuations in Millenniums and its joint ventures operating results.

The
historical operating results of Millennium and its joint ventures reflect the cyclical and volatile nature of the supply-demand balance in the chemical industry, and their future operating results are expected to continue to be affected by this
cyclicality and volatility. This cyclicality and volatility results in significant fluctuations in profits and cash flow from period to period and over the business cycles.

##### Table of Contents

##### Index to Financial Statements

Conditions for ethylene and its derivatives, and acetyls, are cyclical and volatile, and
these businesses are particularly sensitive to capacity additions. These businesses historically have experienced alternating periods of capacity shortages leading to tight supply, causing prices and profit margins to increase, followed by periods
when substantial capacity is added, resulting in oversupply, declining capacity utilization rates and declining prices and profit margins. The volatility these businesses experience occurs as a result of changes in supply and demand for products,
changes in energy prices and changes in various other economic conditions around the world.

Although less cyclical and volatile than ethylene and its derivatives, and acetyls, demand for TiO2also has fluctuated from year to year. For example, the U.S. housing market began experiencing a slowdown during the second half of 2006, which adversely impacted demand for and profitability of Millenniums TiO2business.

The chemical industry has experienced tight supply in many product areas and increased demand as the global economy has improved over the past several years. As a result, profitability in the industry increased, even in a world of volatile
raw material and energy costs. However, the sustainability of these positive business conditions remains subject to uncertainty. The global economic and political environment continues to be uncertain, and a recession or other negative changes could
result in a decline in demand and place pressure on Millenniums and its joint ventures results of operations. In addition, new capacity additions by some participants in the industry, especially those in the Middle East and Asia that
began in 2006 and are expected to continue through the latter part of the decade, could lead to another period of oversupply and poor profitability.

Millennium and its joint ventures may reduce production at or idle a facility for an extended period of time or exit a business because of an oversupply of a particular product and/or a lack of demand for that
particular product, or high raw material prices, which makes production uneconomical. Any decision to permanently close facilities or exit a business would result in impairment and other charges to earnings. Temporary outages sometimes last for
several quarters or, in certain cases, longer, and could cause Millennium and its joint ventures to incur costs, including the expenses of maintaining and restarting these facilities. It is possible that factors such as increases in raw material
costs or lower demand in the future will cause Millennium or its joint ventures to reduce operating rates, idle facilities or exit uncompetitive businesses.

External factors beyond Millenniums or its joint ventures control can cause fluctuations in demand for their products and in their prices and margins, which may result in lower
operating results.

External factors beyond Millenniums or its joint ventures control can cause
volatility in the price of raw materials and other operating costs, as well as significant fluctuations in demand for their products and can magnify the impact of economic cycles on their businesses. Examples of external factors include:



| |  |  | supply of and demand for raw materials;
| | - |  | ---------------------------------------



| |  |  | changes in customer buying patterns and demand for Millenniums and its joint ventures products;
| | - |  | -------------------------------------------------------------------------------------------------



| |  |  | general economic conditions;
| | - |  | ----------------------------



| |  |  | domestic and international events and circumstances;
| | - |  | ----------------------------------------------------



| |  |  | competitor actions;
| | - |  | -------------------



| |  |  | governmental regulation in the U.S. and abroad; and
| | - |  | ---------------------------------------------------



| |  |  | severe weather and natural disasters.
| | - |  | -------------------------------------

Millennium believes that events in the Middle East have had an impact on its acetyls business and Equistars businesses in recent years and may continue to do so. In addition, a number of Millenniums and
its joint ventures products are highly dependent on durable goods markets, such as the housing and automotive markets, which also are cyclical and impacted by many of the external factors referenced above. Many of Millenniums and its
joint ventures products are components of other chemical products that, in turn, are subject to the supply-demand balance of the chemical industry and general economic conditions. The global economy has remained strong, with relatively stable
demand for Millenniums and its joint ventures products. This has occurred even as the volatility and elevated level of prices for crude oil and natural gas have resulted in increased raw material costs. However, the



14

##### Index to Financial Statements

impact of the factors cited above and others may once again cause a slowdown in the business cycle, reducing demand and lowering operating rates and,
ultimately, reducing profitability.

Millennium and its joint ventures sell commodity products in highly competitive
global markets and face significant price pressures.

Millennium and its joint ventures sell their products in
highly competitive global markets. Due to the commodity nature of certain of their products, competition in these markets is based primarily on price and to a lesser extent on product performance, product quality, product deliverability, reliability
of supply and customer service. As a result, Millennium and its joint ventures generally are not able to protect their market position for these products by product differentiation and may not be able to pass on cost increases to their customers.

In addition, Millennium and its joint ventures face increased competition from companies that may have different cost
structures or strategic goals than Millennium and its joint ventures, such as privately-held companies, large integrated oil companies (many of which also have chemical businesses), government-owned businesses, and companies that receive subsidies
or other government incentives to produce certain products in a specified geographic region. Increased competition from these companies, especially in Equistars ethylene business, could limit Millenniums and its joint ventures
ability to increase product sales prices in response to raw material and other cost increases, or could cause Millennium and its joint ventures to reduce product sales prices to compete effectively, which could reduce their profitability.

Accordingly, increases in raw material and other costs may not necessarily correlate with changes in prices for these
products, either in the direction of the price change or in magnitude. In addition, their ability to increase product sales prices, and the timing of those increases, are affected by the supply-demand balances for their products, as well as the
capacity utilization rates for those products. Timing differences in pricing between rising raw material costs, which may change daily, and contract product prices, which in many cases are negotiated only monthly or less often, sometimes with an
additional lag in effective dates for increases, have reduced and may continue to reduce profitability.

Further,
volatility in costs and pricing can result in commercial disputes with customers and suppliers with respect to interpretations of complex contractual arrangements. Significant adverse resolution of any such disputes also could reduce profitability.

Millenniums international operations are subject to exchange rate fluctuations, exchange controls, political
risks and other risks relating to non-U.S. operations.

Millennium has substantial international operations, which
are subject to the risks of doing business abroad, including fluctuations in currency exchange rates, transportation delays and interruptions, political and economic instability and disruptions, restrictions on the transfer of funds, the imposition
of duties and tariffs, import and export controls, changes in governmental policies, labor unrest and current and changing regulatory environments. These events could reduce the demand for Millenniums products internationally, decrease the
prices at which it can sell its products internationally or disrupt production or other operations internationally, which could reduce its operating results. In addition, Millennium and Equistar obtain a substantial portion of their principal raw
materials from sources outside the U.S., which are subject to these same risks. Although Millennium and Equistar have compliance programs and processes intended to ensure compliance with applicable customs, currency exchange control regulations,
transfer pricing regulations or any other laws or regulations to which they may be subject, they are subject to the risk that their compliance could be challenged. Furthermore, these laws may be modified, the result of which may be to prevent or
limit non-U.S. subsidiaries from transferring cash to Millennium. For geographic data, see Note 21 to the Consolidated Financial Statements.

In addition, Millennium generates revenue from export sales and operations conducted outside the U.S. that may be denominated in currencies other than the relevant functional currency. Exchange rates between these
currencies and U.S. dollars in recent years have fluctuated significantly and may do so in the future. Future events, which may significantly increase or decrease the risk of future movement in foreign currencies in which it conducts its business,
cannot be predicted. Millennium also may hedge certain revenues and costs using derivative instruments to minimize the impact of changes in the exchange rates of those currencies compared to the respective



15

##### Table of Contents

##### Index to Financial Statements

functional currencies. It is possible that fluctuations in foreign exchange rates will result in reduced operating results.

Millenniums and its joint ventures operations and assets are subject to extensive environmental, health and safety and
other laws and regulations, which could result in material costs or liabilities.

Millennium and its joint ventures
cannot predict with certainty the extent of future liabilities and costs under environmental, health and safety and other laws and regulations and whether liabilities and costs will be material. Millennium and its joint ventures also may face
liability for alleged personal injury or property damage due to exposure to chemicals or other hazardous substances at their facilities or chemicals that they manufacture, handle or own. In addition, because the chemical products of Millennium and
its joint ventures are components of a variety of other end-use products, Millennium and its joint ventures, along with other members of the chemical industry, are inherently subject to potential claims related to those end-use products. Although
claims of the types described above have not historically had a material impact on Millenniums or its joint ventures operations, a substantial increase in the success of these types of claims could result in the expenditure of a
significant amount of cash by Millennium or its joint ventures to pay claims, and could reduce their operating results.

Millennium and its joint ventures (together with the industries in which they operate) are subject to extensive national, state and local environmental laws and regulations concerning, and are required to have permits and licenses
regulating, emissions to the air, discharges onto land or waters and the generation, handling, storage, transportation, treatment and disposal of waste materials. Many of these laws and regulations provide for substantial fines and potential
criminal sanctions for violations. Some of these laws and regulations are subject to varying and conflicting interpretations. In addition, some of these laws and regulations require Millennium and its joint ventures to meet specific financial
responsibility requirements. Millennium cannot accurately predict future developments, such as increasingly strict environmental laws, and inspection and enforcement policies, as well as higher compliance costs, which might affect the handling,
manufacture, use, emission or disposal of products, other materials or hazardous and non-hazardous waste. Some risk of environmental costs and liabilities is inherent in Millenniums and its joint ventures operations and products, as it
is with other companies engaged in similar businesses, and there is no assurance that material costs and liabilities will not be incurred. In general, however, with respect to the costs and risks described above, Millennium does not expect that it
or its joint ventures will be affected differently than the rest of the chemical industry where their facilities are located.

Environmental laws may have a significant effect on the nature and scope of cleanup of contamination at current and former operating facilities, the costs of transportation and storage of raw materials and finished products and the costs of
the storage and disposal of wastewater. Also, U.S. Superfund statutes may impose joint and several liability for the costs of remedial investigations and actions on the entities that generated waste, arranged for disposal of the wastes,
transported to or selected the disposal sites and the past and present owners and operators of such sites. All such responsible parties (or any one of them, including Millennium and its joint ventures) may be required to bear all of such costs
regardless of fault, the legality of the original disposal or ownership of the disposal site. In addition, similar environmental laws and regulations that have been or may be enacted in countries outside of the U.S. may impose similar liabilities
and costs upon Millennium.

Millennium and its joint ventures have on-site solid-waste management units at several
facilities. It is anticipated that corrective measures will be necessary to comply with federal and state requirements with respect to these facilities. Millennium and its joint ventures also have liabilities under the Resource Conservation and
Recovery Act and various state and non-U.S. government regulations related to several current and former plant sites. Millennium and its joint ventures also are responsible for a portion of the remediation of certain off-site waste disposal
facilities. Millennium and its joint ventures are contributing funds to the cleanup of several waste sites throughout the U.S. under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) and the Superfund
Amendments and Reauthorization Act of 1986, including the Kalamazoo River Superfund Site discussed below. Millennium and its joint ventures also have been named as potentially responsible parties at several other sites. Millenniums policy is
to accrue remediation expenses when it is probable that such efforts will be required and the related expenses can be reasonably estimated. Estimated costs for future environmental compliance and remediation are necessarily imprecise due to such
factors as the continuing evolution of environmental laws and regulatory requirements, the availability and application of technology, the identification of presently unknown remediation sites and the allocation of costs among the potentially
responsible parties under

applicable statutes. For further discussion regarding Millenniums and its joint ventures environmental matters and related accruals (including
those discussed in this risk factor), and environmentally-related capital expenditures, see also Item 1. BusinessEnvironmental Capital Expenditures, Item 3. Legal Proceedings  Environmental Matters,
Item 7. Managements Discussion and Analysis of Financial Condition and Results of OperationsEnvironmental Matters and Note 18 to the Consolidated Financial Statements. If actual expenditures exceed the amounts accrued,
that could have an adverse effect on Millenniums and its joint ventures results of operations and financial position.

Kalamazoo River Superfund SiteA Millennium subsidiary has been identified as a Potential Responsible Party (PRP) with respect to the Kalamazoo River Superfund Site. The site involves cleanup of river sediments and
floodplain soils contaminated with polychlorinated biphenyls, cleanup of former paper mill operations, and cleanup and closure of landfills associated with the former paper mill operations. Litigation concerning the matter commenced in
December 1987 but was subsequently stayed and is being addressed under CERCLA. In 2000, the Kalamazoo River Study Group (the KRSG), of which the Millennium subsidiary and other PRPs are members, submitted to the State of Michigan a
Draft Remedial Investigation and Draft Feasibility Study, which evaluated a number of remedial options for the river. The estimated costs for these remedial options ranged from $0 to $2.5 billion.

At the end of 2001, the U.S. Environmental Protection Agency (EPA) took lead responsibility for the river portion of the site
at the request of the State of Michigan. In 2004, the EPA initiated a confidential process to facilitate discussions among the agency, the Millennium subsidiary, other PRPs, the Michigan Departments of Environmental Quality and Natural Resources,
and certain federal natural resource trustees about the need for additional investigation activities and different possible approaches for addressing the contamination in and along the Kalamazoo River. These discussions are continuing.

As of December 31, 2006, the probable future remediation spending associated with the river cannot be determined with certainty.
Although the KRSG study identified a broad range of remedial options, not all of those options would represent reasonably possible outcomes. Management does not believe that it can identify a single remedy among those options that would represent
the highest-cost reasonably possible outcome. However, in 2004, Millennium recognized a liability representing Millenniums interim allocation of 55% of the $73 million total of estimated cost of bank stabilization, recommended as the
preferred remedy in 2000 by the KRSG study, and of certain other costs. At December 31, 2006, the balance of this liability was $58 million.

In addition, in 2004, Millennium recognized a liability primarily related to Millenniums estimated share of remediation costs for two former paper mill sites and associated landfills, which are also part of the
Kalamazoo River Superfund Site. At December 31, 2006, the balance of the liability was $48 million. Although no final agreement has been reached as to the ultimate remedy for these locations, Millennium has begun remediation activity
related to these sites.

Millenniums ultimate liability for the Kalamazoo River Superfund Site will depend on many
factors that have not yet been determined, including the ultimate remedy selected, the determination of natural resource damages, the number and financial viability of the other PRPs, and the determination of the final allocation among the PRPs.
Millenniums ultimate liability for the Kalamazoo River Superfund Site will not be affected by the proposed sale of the inorganic chemicals business, which is anticipated to close in the first half of 2007.

Other Regulatory RequirementsIn addition to the matters described above, Millennium and its joint ventures are subject to
other material regulatory requirements that could result in higher operating costs, such as regulatory requirements relating to the security of chemical facilities, and the transportation, exportation or registration of products. Although Millennium
and its joint ventures have compliance programs and other processes intended to ensure compliance with all such regulations, Millennium and its joint ventures are subject to the risk that their compliance with such regulations could be challenged.
Non-compliance with certain of these regulations could result in the incurrence of additional costs, penalties or assessments that could be significant.

Proceedings related to the alleged exposure to lead-based paints and lead pigments
could require Millennium to spend material amounts in litigation and settlement costs and judgments.

Together with
alleged past manufacturers of lead-based paint and lead pigments for use in paint, Millennium has been named as a defendant in various legal proceedings alleging personal injury, property damage, and remediation costs allegedly associated with the
use of these products. The plaintiffs include individuals and governmental entities, and seek recovery under a variety of theories, including negligence, failure to warn, breach of warranty, conspiracy, market share liability, fraud,
misrepresentation and nuisance. The majority of these legal proceedings assert unspecified monetary damages in excess of the statutory minimum and, in certain cases, equitable relief such as abatement of lead-based paint in buildings. These legal
proceedings are in various trial stages and post-dismissal settings, some of which are on appeal. One legal proceeding relating to lead pigment or paint was tried in 2002. On October 29, 2002, the judge in that case declared a mistrial after
the jury declared itself deadlocked. The sole issue before the jury was whether lead pigment in paint in and on Rhode Island buildings constituted a public nuisance. The re-trial of this case began on November 1, 2005. On
February 22, 2006, a jury returned a verdict in favor of the State of Rhode Island finding that the cumulative presence of lead pigments in paints and coatings on buildings in the state constitutes a public nuisance; that a Millennium
subsidiary, Millennium Holdings, LLC, and other defendants either caused or substantially contributed to the creation of the public nuisance; and that those defendants, including the Millennium subsidiary, should be ordered to abate the public
nuisance. On February 28, 2006, the judge held that the state could not proceed with its claim for punitive damages. As a result, the jury was discharged. The court has not entered a final judgment on the jurys verdict; however, on
February 26, 2007, the court issued its decision denying the post-verdict motions of the defendants, including Millennium, for a mistrial or a new trial. The court concluded that it would enter an order of abatement and appoint a special master to
assist the court in determining the scope of the abatement remedy.

While Millennium believes that it has valid defenses to
all the lead-based paint and lead pigment proceedings and is vigorously defending them, litigation is inherently subject to many uncertainties. Additional lead-based paint and lead pigment litigation may be filed against Millennium in the future
asserting similar or different legal theories and seeking similar or different types of damages and relief, and any adverse court rulings or determinations of liability, among other factors, could affect this litigation by encouraging an increase in
the number of future claims and proceedings. In addition, from time to time, legislation and administrative regulations have been enacted or proposed to impose obligations on present and former manufacturers of lead-based paint and lead pigment
respecting asserted health concerns associated with such products or to overturn successful court decisions. Millennium is unable to predict the outcome of lead-based paint and lead pigment litigation, the number or nature of possible future claims
and proceedings, and the effect that any legislation and/or administrative regulations may have on Millennium. In addition, Millennium cannot reasonably estimate the scope or amount of the costs and potential liabilities related to such litigation,
or any such legislation and regulations. Thus, any liability Millennium incurs with respect to pending or future lead-based paint or lead pigment litigation, or any legislation or regulations could, to the extent not covered or reduced by insurance
or other recoveries, have a material impact on Millenniums results of operations. In addition, Millennium has not accrued any liabilities for judgments or settlements against Millennium resulting from lead-based paint and lead pigment
litigation. Any liability that Millennium may ultimately incur with respect to lead-based paint and lead pigment litigation will not be affected by the proposed sale of the inorganic chemicals business, which is anticipated to close in the first
half of 2007. See Item 3. Legal ProceedingsLitigation Matters for additional discussion regarding lead-based paint and lead pigment litigation.

Interruptions of operations at the facilities of Millennium and its joint ventures may result in liabilities or lower operating results.

Millennium and its joint ventures own and operate large-scale chemical facilities, and their operating results are dependent on the
continued operation of their various production facilities and the ability to complete construction and maintenance projects on schedule. Material operating interruptions at Millenniums or its joint ventures facilities, including, but
not limited to, interruptions caused by the events described below, may materially reduce the productivity and profitability of a particular manufacturing facility, or Millennium as a whole, during and after the period of such operational
difficulties. For example, unscheduled downtime at Millenniums U.K. facility had a significant negative impact on Millenniums operating results in 2006.

Although Millennium and its joint ventures take precautions to enhance the safety of
their operations and minimize the risk of disruptions, their operations, along with the operations of other members of the chemical industry, are subject to hazards inherent in chemical manufacturing and the related storage and transportation of raw
materials, products and wastes. These potential hazards include:



| |  |  | pipeline leaks and ruptures;
| | - |  | ----------------------------



| |  |  | explosions;
| | - |  | -----------



| |  |  | fires;
| | - |  | ------



| |  |  | severe weather and natural disasters;
| | - |  | -------------------------------------



| |  |  | mechanical failure;
| | - |  | -------------------



| |  |  | unscheduled downtimes;
| | - |  | ----------------------



| |  |  | supplier disruptions;
| | - |  | ---------------------



| |  |  | labor shortages or other difficulties;
| | - |  | --------------------------------------



| |  |  | transportation interruptions;
| | - |  | -----------------------------



| |  |  | remediation complications;
| | - |  | --------------------------



| |  |  | chemical spills;
| | - |  | ----------------



| |  |  | discharges or releases of toxic or hazardous substances or gases;
| | - |  | -----------------------------------------------------------------



| |  |  | storage tank leaks;
| | - |  | -------------------



| |  |  | other environmental risks; and
| | - |  | ------------------------------



| |  |  | terrorist acts.
| | - |  | ---------------

Some of these
hazards can cause personal injury and loss of life, severe damage to or destruction of property and equipment and environmental damage, and may result in suspension of operations and the imposition of civil or criminal penalties. Furthermore,
Millennium and its joint ventures also will continue to be subject to present and future claims with respect to workplace exposure, workers compensation and other matters.

Millennium and its joint ventures maintain property, business interruption and casualty insurance that they believe are in accordance
with customary industry practices, but they are not fully insured against all potential hazards incident to their businesses, including losses resulting from natural disasters, war risks or terrorist acts. Changes in insurance market conditions have
caused, and may in the future cause, premiums and deductibles for certain insurance policies to increase substantially and, in some instances, for certain insurance to become unavailable or available only for reduced amounts of coverage. If
Millennium or its joint ventures were to incur a significant liability for which they were not fully insured, that company might not be able to finance the amount of the uninsured liability on terms acceptable to it or at all, and might be obligated
to divert a significant portion of its cash flow from normal business operations.

Conflicts of interest between
Lyondell, Equistar and/or Millennium could be resolved in a manner that may be perceived to be adverse to Millennium and/or Equistar.

Lyondell owns 70.5% of Equistar, and Millennium owns the remaining 29.5% of Equistar. As a result of Lyondells November 30, 2004 acquisition of Millennium, Millennium and Equistar are wholly-owned
subsidiaries of Lyondell. All executive officers of Millennium and Equistar and all members of Equistars Partnership Governance Committee and Millenniums Board of Directors also serve as officers of Lyondell. Conflicts of interest may
arise between Lyondell, Equistar and/or Millennium when decisions arise that could have different implications for Lyondell, Equistar and/or Millennium. Their respective debt agreements generally require related party transactions to be on an
arms-length basis; however, because Lyondell owns both Millennium and Equistar, conflicts of interest could be resolved in a manner that may be perceived to be adverse to Millennium and/or Equistar.

Millennium and Equistar depend to a significant degree on Lyondell for the
administration of their businesses, and Equistar has product supply arrangements with its owners and other related parties. If those parties do not fulfill their obligations under the arrangements, Millenniums and/or Equistars revenues,
margins and cash flow could be adversely affected.

Lyondell and Equistar and parties related to them have various
agreements and transactions with Millennium. For example, Millennium is party to shared services, loaned employee and operating arrangements with Lyondell and Equistar pursuant to which Lyondell, Equistar and Millennium provide many administrative
and operating services to each other. Lyondell provides to Millennium and Equistar services that are essential to the administration and management of Millenniums and Equistars businesses, which from time to time may include information
technology, human resources, sales and marketing, raw material supply, supply chain, health, safety and environmental, engineering, research and development, facility services, legal, accounting, treasury, internal audit and tax services.
Accordingly, Millennium and Equistar depend to a significant degree on Lyondell for the administration of their businesses. If Lyondell did not fulfill its obligations under the shared services arrangement, it would disrupt Millenniums and
Equistars businesses and could have a material adverse effect on their businesses and results of operations. In addition, Equistar has product supply agreements with Lyondell and Millennium and various other related parties pursuant to which
Equistar sells a substantial amount of its products. Equistar expects to continue to derive a significant portion of its business from transactions with these parties. If they are unable or otherwise cease to purchase Equistars products,
Equistars revenues and margins and, therefore, Millenniums cash flow could be adversely affected.

Millennium pursues acquisitions, dispositions and joint ventures, which may not yield the expected benefits.

Millennium may purchase or sell assets or enter into contractual arrangements or joint ventures in an effort to generate value. For example, on February 23, 2007, Millennium and Cristal signed an agreement for a proposed sale of
Millenniums worldwide inorganic chemicals business to Cristal for $1.05 billion, in cash, plus the assumption of specified liabilities. Transactions that Millennium pursues may be intended to, among other things, result in the realization of
synergies, the creation of efficiencies or the generation of cash to reduce debt. To the extent permitted under Millenniums credit facility and other debt agreements, some of these transactions may be financed with additional borrowings by
Millennium or its joint ventures. Although these transactions may be expected to yield longer-term benefits if the expected efficiencies and synergies of the transactions are realized, they could reduce the operating results of Millennium or its
joint ventures in the short term because of the costs, charges and financing arrangements associated with such transactions or the benefits of a transaction may not be realized to the extent anticipated. Other transactions may advance future cash
flows from some of Millenniums or its joint ventures businesses, thereby yielding increased short-term liquidity, but consequently resulting in lower cash flows from these operations over the longer term.

The pursuit of strategic transactions also may have other consequences. For example, as Millennium pursues the sale of the inorganic
chemicals business, its operating results could be negatively impacted if Millennium experiences a loss of employees, customers or suppliers or an increase in operating or other costs or operating interruptions.

Risks Relating to Debt

Millenniums consolidated balance sheet is highly levered,
and Millenniums business and future prospects could be limited by its significant amount of debt and other financial obligations.

Millenniums consolidated balance sheet is highly levered. Millenniums total consolidated debt was $853 million at December 31, 2006, or 82% of its total capitalization. In addition, Millennium
has contractual commitments and ongoing pension and post-retirement benefit obligations that will require cash contributions in 2007 and beyond, as described in Contractual and Other Obligations under Item 7.
Managements Discussion and Analysis of Financial Condition and Results of Operations.

Millenniums level of debt and other obligations could have significant adverse
consequences on its business and future prospects, including the following:



| |  |  | Millennium may not be able to obtain financing in the future for working capital, capital expenditures, acquisitions, debt service requirements or other
purposes;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | less levered competitors could have a competitive advantage because they have lower debt service requirements; and
| | - |  | ------------------------------------------------------------------------------------------------------------------



| |  |  | in the event of poor business conditions, Millennium may be less able to take advantage of significant business opportunities and to react to changes in market
or industry conditions than its competitors.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

For a discussion regarding Millenniums ability to pay
or refinance its debt, see the Liquidity and Capital Resources section under Item 7. Managements Discussion and Analysis of Financial Condition and Results of Operations.

Millennium and Equistar each require a significant amount of cash to service their indebtedness, and the ability of each of them to
generate cash depends on many factors beyond their control.

Due to debt covenant limitations on transferring cash
between the entities discussed below in this Item 1A. Risk Factors, the ability of each of Millennium and Equistar to make payments on and to refinance its respective indebtedness may depend solely upon its individual ability to generate
cash. Each of Millennium and Equistar is separately responsible for its respective outstanding debt (except that $150 million of Equistars debt is guaranteed by Lyondell). The businesses of each of Millennium and Equistar may not generate
sufficient cash flow from operations to meet their respective debt service obligations, future borrowings may not be available under current or future credit facilities of each entity in an amount sufficient to enable each of them to pay their
respective indebtedness at or before maturity, and each entity may not be able to refinance its respective indebtedness on reasonable terms, if at all. Factors beyond the control of Millennium and Equistar affect the ability of each of them to make
these payments and refinancings. These factors include those discussed elsewhere in these Risk Factors and the Forward-Looking Statements section of this Annual Report on Form 10-K.

Further, the ability of Millennium and Equistar to fund capital expenditures and working capital depends on the ability of each entity to
generate cash and depends on the availability of funds under lines of credit and other liquidity facilities. If, in the future, sufficient cash is not generated from their respective operations to meet their respective debt service obligations and
sufficient funds are not available under lines of credit or other liquidity facilities, Millennium and Equistar each may need to reduce or delay non-essential expenditures, such as capital expenditures and research and development efforts. In
addition, Millennium and Equistar may need to refinance debt, obtain additional financing or sell assets, which they may not be able to do on reasonable terms, if at all.

Debt and other agreements restrict Millenniums and Equistars ability to take certain actions and require the maintenance of certain financial ratios; failure to comply with
these requirements could result in acceleration of debt.

Millenniums DebtMillennium has a U.S.
and an Australian revolving credit facility, an Australian term loan facility and a U.K. revolving credit facility. Millenniums facilities and its indentures contain covenants that, subject to exceptions, restrict, among other things,
dividends, debt incurrence, lien incurrence, investments, sale and leaseback transactions, sales of assets, affiliate transactions, mergers, accounts receivable securitization transactions, purchase of equity and payments on indebtedness. Pursuant
to these provisions, Millennium is prohibited from making restricted payments, including paying certain dividends. Other than the U.K. facility, Millenniums facilities also contain covenants that require the maintenance of specified financial
ratios: (1) the Leverage Ratio (as defined) is required to be less than 4.50 to 1 and (2) the Interest Coverage Ratio (as defined) for any period of four consecutive fiscal quarters is required to be equal to or greater than 2.25 to 1.
Millenniums U.K. facility does not require the maintenance of specified financial ratios as long as certain conditions are met.

##### Index to Financial Statements

Equistars Debt and Accounts Receivable FacilityEquistar has an
inventory-based revolving credit facility and an accounts receivable sales facility. Both of these facilities and Equistars indentures contain covenants that, subject to exceptions, restrict, among other things, lien incurrence, debt
incurrence, dividends, sales of assets, investments, accounts receivable securitizations, purchase of equity, payments on indebtedness, affiliate transactions, sale and leaseback transactions and mergers. Equistars credit facility does not
require the maintenance of specified financial ratios as long as certain conditions are met. Some of Equistars indentures require additional interest payments to the note holders if Equistar makes distributions when Equistars Fixed
Charge Coverage Ratio (as defined) is less than 1.75 to 1. Equistar met this ratio as of December 31, 2006.

Effects of a BreachA breach by Millennium or Equistar of any of the covenants or other requirements in their respective debt instruments could (1) permit their respective note holders or lenders to declare the outstanding
debt under the breached debt instrument due and payable, (2) permit the lenders under their respective credit facilities to terminate future lending commitments and (3) permit acceleration of the breaching entitys other debt
instruments that contain cross-default or cross-acceleration provisions. The respective debt agreements of Millennium and Equistar contain various event of default and cross-default provisions. It is not likely that Millennium or Equistar, as the
case may be, would have, or be able to obtain, sufficient funds to make these accelerated payments. In that event, the breaching entitys lenders could proceed against any assets that secure their debt. Similarly, the breach by Equistar of
covenants in its accounts receivable sales facility would permit the counterparties to terminate further purchases of interests in accounts receivable and to receive all collections from previously sold interests until they had collected on their
interests in those receivables, thus reducing Equistars liquidity.

Debt covenants limit transfers of cash
between Lyondell, Millennium and Equistar.

Although Equistar and Millennium are wholly-owned subsidiaries of
Lyondell, debt covenants limit the ability to transfer cash among Lyondell, Equistar and Millennium. For example, Lyondells indentures contain a covenant that prohibits it from making investments in subsidiaries and joint ventures that are not
restricted subsidiaries as defined in the indentures, subject to limited exceptions. Neither Millennium nor Equistar currently is a restricted subsidiary. Lyondells credit facility also contains a covenant that places limitations on its
ability to make investments in joint ventures. Millenniums flexibility to make investments in Equistar also is limited by its debt covenants. As a result, Lyondells cash flow may not be available to fund cash needs of Millennium, and the
cash flow of Lyondell and Millennium may not be available to fund cash needs of Equistar, such as servicing debt or paying capital expenditures.

Some of Equistars indentures require additional interest payments to the note holders if Equistar makes distributions when Equistar does not meet a specified fixed charge coverage ratio. Equistar met this ratio
as of December 31, 2006. In addition, Equistars credit facility prohibits the payment of distributions during any default under the facility. These provisions may deter or limit the movement of cash from Equistar to Lyondell and
Millennium.

Applicable laws may also limit the amounts Equistar is permitted to pay as distributions to Lyondell and
Millennium. The ability of Equistar to distribute cash to Lyondell and Millennium, and the ability of Lyondell to make cash investments in Millennium, also is dependent upon their economic performance, which is dependent on a variety of factors,
including factors described elsewhere in these Risk Factors and the Forward-Looking Statements section of this Annual Report on Form 10-K.

FORWARD-LOOKING STATEMENTS

Certain of the statements contained in this report are
forward-looking statements within the meaning of the federal securities laws. Forward-looking statements can be identified by words such as estimate, believe, expect, anticipate,
plan, budget or other words that convey the uncertainty of future events or outcomes. Many of these forward-looking statements have been based on expectations and assumptions about future events that may prove to be
inaccurate. While management considers these expectations and assumptions to be reasonable, they are inherently subject to significant business, economic, competitive, regulatory and other risks, contingencies and uncertainties, most of which are
difficult to predict and many of which are beyond Millenniums control. Millenniums or its joint ventures actual results could differ materially from those anticipated in these forward-looking statements as a result of certain
factors, including but not limited to:



| |  |  | the availability, cost and price volatility of raw materials and utilities,
| | - |  | ---------------------------------------------------------------------------



| |  |  | the supply/demand balances for Millenniums and its joint ventures products, and the related effects of industry production capacities and operating
rates,
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | operating interruptions (including leaks, explosions, fires, weather-related incidents, mechanical failure, unscheduled downtime, supplier disruptions, labor
shortages or other labor difficulties, transportation interruptions, spills and releases and other environmental risks),
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | legal, tax and environmental proceedings,
| | - |  | -----------------------------------------



| |  |  | uncertainties associated with the U. S. and worldwide economies, including those due to political tensions in the Middle East and elsewhere,
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the cyclical nature of the chemical industry,
| | - |  | ---------------------------------------------



| |  |  | Millenniums ability to implement its business strategies, including Millenniums ability to successfully complete the proposed sale of the inorganic
chemicals business in the time period anticipated, and for the purchase price and on the other terms set forth in the transaction agreement,
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | current and potential governmental regulatory actions in the U. S. and in other countries,
| | - |  | ------------------------------------------------------------------------------------------



| |  |  | terrorist acts and international political unrest,
| | - |  | --------------------------------------------------



| |  |  | risks of doing business outside the U.S., including foreign currency fluctuations,
| | - |  | ----------------------------------------------------------------------------------



| |  |  | access to capital markets,
| | - |  | --------------------------



| |  |  | competitive products and pricing pressures, and
| | - |  | -----------------------------------------------



| |  |  | technological developments.
| | - |  | ---------------------------

Any of these factors, or a combination of these factors, could materially affect Millenniums or its joint ventures future results of operations and the ultimate accuracy of the forward-looking statements.
These forward-looking statements are not guarantees of Millenniums or its joint ventures future performance, and Millenniums or its joint ventures actual results and future developments may differ materially from those
projected in the forward-looking statements. Management cautions against putting undue reliance on forward-looking statements or projecting any future results based on such statements or present or prior earnings levels.

All forward-looking statements in this Form 10-K are qualified in their entirety by the cautionary statements contained in this section
and elsewhere in this report. See Item 1. Business, Item 1A. Risk Factors, Item 3. Legal Proceedings, Item 7. Managements Discussion and Analysis of Financial Condition and Results of Operations
and Item 7A. Disclosure of Market Risk for additional information about factors that may affect the businesses and operating results of Millennium and its joint ventures. These factors are not necessarily all of the important factors
that could affect Millennium and its joint ventures. Use caution and common sense when considering these forward-looking statements. Millennium does not intend to update these statements unless securities laws require it to do so.

In addition, this report contains summaries of contracts and other documents. These summaries may not contain all of the information that
is important to an investor, and reference is made to the actual contract or document for a more complete understanding of the contract or document involved.

INDUSTRY AND OTHER INFORMATION

The data included or incorporated by reference in this report
regarding the chemical industry, product capacity and ranking, including Millenniums and Equistars respective capacity positions, the capacity positions of their competitors for certain products and expected rates of demand, is based on
independent industry publications, reports from government agencies or other published industry sources and estimates of Millennium and/or Equistar. These estimates are based on information obtained from Millenniums and/or Equistars
customers, distributors, suppliers, trade and business organizations and other contacts in the markets in which Millennium and Equistar operate and managements knowledge and experience. These estimates involve risks and uncertainties and are
subject to change based on various factors, including those discussed under Item 1A. Risk Factors and Forward-Looking Statements.

NON-GAAP FINANCIAL MEASURES

The body of generally accepted accounting principles is commonly
referred to as GAAP. For this purpose, a non-GAAP financial measure is generally defined by the Securities and Exchange Commission as one that purports to measure historical or future financial performance, financial position or cash
flows but excludes or includes amounts that would not be so adjusted in the most comparable U.S. GAAP measure. From time to time Millennium discloses so-called non-GAAP financial measures, primarily EBITDA, or earnings before interest, taxes,
depreciation and amortization of long-lived assets. The non-GAAP financial measures described herein or in other documents issued by Millennium are not a substitute for the GAAP measures of earnings, for which management has responsibility.

Millennium sometimes uses EBITDA in its communications with investors, financial analysts and the public. This is because
EBITDA is perceived as a useful and comparable measure of operating performance and the contribution of operations to liquidity. For example, interest expense is dependent on the capital structure and credit rating of a company. However, debt
levels, credit ratings and, therefore, the impact of interest expense on earnings vary in significance between companies. Similarly, the tax positions of individual companies can vary because of their differing abilities to take advantage of tax
benefits, with the result that their effective tax rates and tax expense can vary considerably. Finally, companies differ in the age and method of acquisition of productive assets, and thus the relative costs of those assets, as well as in the
depreciation (straight-line, accelerated, units of production) method, which can result in considerable variability in depreciation and amortization expense between companies. Thus, for comparison purposes, management believes that EBITDA can be
useful as an objective and comparable measure of operating profitability and the contribution of operations to liquidity because it excludes these elements of earnings that do not provide information about the current operations of existing assets.
Accordingly, management believes that disclosure of EBITDA can provide useful information to investors, financial analysts and the public in their evaluation of companies operating performance and the contribution of operations to liquidity.

Millennium also sometimes reports adjusted net income (loss) or adjusted EBITDA, excluding specified items that are
unusual in nature or are not comparable from period to period and that are included in GAAP measures of earnings. Management believes that excluding these items may help investors compare operating performance between two periods. Such adjusted data
is always reported with an explanation of the items that are excluded.

|Item 3. | Legal Proceedings
|------- | -----------------

Litigation Matters

Millennium and its joint ventures are, from time to time, defendants in
lawsuits, some of which are not covered by insurance. Many of these suits make no specific claim for relief. Although final determination of legal liability and the resulting financial impact with respect to any such litigation cannot be ascertained
with any degree of certainty, Millennium does not believe that any ultimate uninsured liability resulting from the legal proceedings in which it or its joint ventures currently are involved (directly or indirectly) will individually, or in the
aggregate, have a material adverse effect on the business or financial position of Millennium. However, the adverse resolution in any reporting period of one or more of these suits could have a material impact on Millenniums results of
operations for that period, which may be mitigated by contribution or indemnification obligations of co-defendants or others, or by any insurance coverage that may be available.

Although Millennium and its joint ventures are involved in numerous and varied legal
proceedings, a significant portion of their outstanding litigation arose in five contexts: (1) claims for personal injury or death allegedly arising out of exposure to the products produced by or located on the premises of the respective
entities; (2) claims for personal injury or death, and/or property damage allegedly arising out of the generation and disposal of chemical wastes at Superfund and other waste disposal sites; (3) claims for personal injury, property damage
and/or air, noise and water pollution allegedly arising out of operations; (4) employment and benefits related claims; and (5) commercial disputes.

In 2004, Millennium received requests from the staff of the Northeast Regional Office of the Securities and Exchange Commission for the voluntary production of documents in connection with an
informal inquiry into the previously disclosed restatement of Millenniums financial statements for the years 1998 through 2002 and for the first quarter of 2003. Millennium has complied with all such requests received.

Together with alleged past manufacturers of lead-based paint and lead pigments for use in paint, Millennium has been named as a defendant
in various legal proceedings alleging personal injury, property damage, and remediation costs allegedly associated with the use of these products. The plaintiffs include individuals and governmental entities, and seek recovery under a variety of
theories, including negligence, failure to warn, breach of warranty, conspiracy, market share liability, fraud, misrepresentation and nuisance. The majority of these legal proceedings assert unspecified monetary damages in excess of the statutory
minimum and, in certain cases, seek equitable relief such as abatement of lead-based paint in buildings. Legal proceedings relating to lead pigment or paint are in various trial stages and post-dismissal settings, some of which are on appeal.

Millenniums defense costs to date for lead-based paint and lead pigment litigation largely have been covered by
insurance. Millennium has not accrued any liabilities for any lead-based paint and lead pigment litigation. Millennium has insurance policies that potentially provide approximately $1.0 billion in indemnity coverage for lead-based paint and lead
pigment litigation. Millenniums ability to collect under the indemnity coverage would depend upon, among other things, the resolution of certain potential coverage defenses that the insurers are likely to assert and the solvency of the various
insurance carriers that are part of the coverage block at the time of such a request. As a result of insurance coverage litigation initiated by Millennium, an Ohio trial court issued a decision in 2002 effectively requiring certain insurance
carriers to resume paying defense costs in the lead-based paint and lead pigment cases. Indemnity coverage was not at issue in the Ohio courts decision. On February 23, 2006, certain Lloyds, London insurance underwriters filed a
declaratory judgment action in the Supreme Court of the State of New York (trial court) against several of their policyholders, including Millennium, contesting their responsibility to provide insurance coverage for all of the lead-based paint and
lead pigment cases, including the Rhode Island case discussed below. On March 14, 2006, Millennium filed a motion to dismiss the New York case in favor of the pre-existing Ohio action, and on April 27, 2006, the Supreme Court of the State
of New York stayed the New York case in favor of the prior-filed Ohio action. On or about October 5, 2006, Lloyds, London filed a notice of appeal of the New York trial courts decision. In addition, on March 7, 2006, Millennium
filed an amended complaint in the Ohio case referenced above that revived its Ohio state court litigation, seeking, among other relief, a declaratory judgment as to the responsibility of all of its insurance carriers for any judgments or settlements
in connection with any lead-based paint and lead pigment litigation involving Millennium. On April 26, 2006, the judge in the Ohio case granted Millenniums motion to amend the complaint to include all insurance carriers. The insurance
carriers have in the past and may in the future attempt to deny indemnity coverage if there is ever a settlement or a final, non-appealable adverse judgment in any lead-based paint or lead pigment case.

After owning the Glidden Paints business for six months, in 1986, a predecessor of a current subsidiary of Millennium sold, through a
stock sale, its Glidden Paints business. As part of that sale, the seller and purchaser agreed to provide indemnification to each other against certain claims made during the first eight years after the sale, and the purchaser agreed to fully
indemnify the seller against such claims made after the eight-year period. With the exception of two cases described below, all pending lead-based paint and lead pigment litigation involving Millennium, including the Rhode Island case, were filed
after the eight-year period. Accordingly, Millennium believes that it is entitled to full indemnification from the purchaser against lead-based paint and lead pigment cases filed after the eight-year period. The purchaser disputes that it has such
an indemnification obligation, and claims that the seller must indemnify it. As Millennium has not paid either a settlement or any judgment, its indemnification claims have not been finally resolved. The only two remaining cases originally filed
within the eight-year period following the 1986 sale of the Glidden Paints business include as parties a current Millennium

subsidiary and an alleged predecessor company. One case filed by the New York City Housing Authority remains inactive. The other matter is a personal injury
case in Ohio. On January 25, 2007, the Ohio Court of Appeals affirmed summary judgment in favor of Millennium and its co-defendants.

Lyondell believes that Millennium has valid defenses to all pending lead-based paint and lead pigment proceedings and is vigorously defending them. However, litigation is inherently subject to many uncertainties.
Additional lead-based paint and lead pigment litigation may be filed against Millennium in the future asserting similar or different legal theories and seeking similar or different types of damages and relief, and any adverse court rulings or
determinations of liability, among other factors, could affect the litigation by encouraging an increase in the number of future claims and proceedings. In addition, from time to time, legislation and administrative regulations have been enacted or
proposed to impose obligations on present and former manufacturers of lead-based paint and lead pigment respecting asserted health concerns associated with such products or to overturn successful court decisions. Millennium is unable to predict the
outcome of lead-based paint and lead pigment litigation, the number or nature of possible future claims and proceedings, or the effect that any legislation and/or administrative regulations may have on Millennium. In addition, management cannot
reasonably estimate the scope or amount of the costs and potential liabilities related to such litigation, or any such legislation and regulations. Accordingly, Lyondell has not accrued any amounts for such litigation.

Millennium is currently named a defendant in 55 cases arising from Gliddens manufacture of lead pigments that are in various stages
of the litigation process. Of these, three have been dismissed in favor of Millennium and its co-defendants by the trial court, but remain open and are on appeal. There are three inactive cases which remain open pending administrative closure by the
courts. The remainder of the cases are in various pre-trial stages. In addition, there are two personal injury cases filed in which Millennium has been named as a defendant, but has not been formally served. Of the 50 open and active cases, most
seek damages for personal injury and are brought by individuals, and ten of the cases seek damages and abatement remedies based on public nuisance and are brought by states, cities and/or counties in five states (California, Missouri, New Jersey,
Ohio and Rhode Island).

On October 29, 2002, after a trial in which the jury deadlocked, the court in State of
Rhode Island v. Lead Industries Association, Inc., et al.(which commenced in the Superior Court of Providence, Rhode Island, on October 13, 1999) declared a mistrial. The sole issue before the jury was whether lead pigment in paint in and
on public and private Rhode Island buildings constituted a public nuisance. The new trial in this case began on November 1, 2005. On February 22, 2006, a jury returned a verdict in favor of the State of Rhode Island finding
that the cumulative presence of lead pigments in paints and coatings on buildings in the state constitutes a public nuisance; that a Millennium subsidiary and other defendants either caused or substantially contributed to the creation of the public
nuisance; and that those defendants, including the Millennium subsidiary, should be ordered to abate the public nuisance. On February 28, 2006, the judge held that the state could not proceed with its claim for punitive damages. As a result,
the jury was discharged. The court has not entered a final judgment on the jurys verdict; however, on February 26, 2007, the court issued its decision denying the post-verdict motions of the defendants, including Millennium, for a mistrial or
a new trial. The court concluded that it would enter an order of abatement and appoint a special master to assist the court in determining the scope of the abatement remedy.

Environmental Matters

From time to time Millennium and its joint ventures receive notices or
inquiries from federal, state or local governmental entities of alleged violations of environmental laws and regulations pertaining to, among other things, the disposal, emission and storage of chemical and petroleum substances, including hazardous
wastes. Any such alleged violations may become the subject of enforcement actions, settlement negotiations or other legal proceedings and may (individually or in the aggregate) involve monetary sanctions of $100,000 or more (exclusive of interest
and costs).

Millenniums accrued liability for future environmental remediation costs at current and former plant
sites and other remediation sites totaled $172 million as of December 31, 2006. The remediation expenditures are expected to occur over a number of years, and not to be concentrated in any single year. In the opinion of management, there
is no material estimable range of reasonably possible loss in excess of the liabilities recorded for environmental remediation. However, it is possible that new information about the sites for which the accrual has been established,

new technology or future developments such as involvement in investigations by regulatory agencies, could require Millennium to reassess its potential
exposure related to environmental matters. The liabilities for individual sites range from less than $1 million to $106 million. The $106 million liability relates to the Kalamazoo River Superfund Site. For additional information
regarding environmental matters, including the liability related to the Kalamazoo River Superfund Site, see Item 1A. Risk FactorsRisks Relating to the BusinessesMillenniums and its joint ventures operations and assets
are subject to extensive environmental, health and safety and other laws and regulations, which could result in material costs or liabilities, Item 7. Managements Discussion and Analysis of Financial Condition and Results of
OperationsEnvironmental Matters and Note 18 to the Consolidated Financial Statements.

A Millennium subsidiary
has been identified as a PRP with respect to the Kalamazoo River Superfund Site. The site involves cleanup of river sediments and floodplain soils contaminated with polychlorinated biphenyls, cleanup of former paper mill operations, and cleanup and
closure of landfills associated with the former paper mill operations. Litigation concerning the matter commenced in December 1987 but was subsequently stayed and is being addressed under CERCLA. Millenniums ultimate liability for the
Kalamazoo River Superfund Site will depend on many factors that have not yet been determined, including the ultimate remedy selected, the determination of natural resource damages, the number and financial viability of the other PRPs, and the
determination of the final allocation among the PRPs.

In December 2006, the State of Texas filed a lawsuit in the District
Court, Travis County, Texas, against Equistar and its owners, Lyondell and Millennium, alleging past violations of various environmental regulatory requirements at Equistars Channelview, Chocolate Bayou and La Porte, Texas facilities and
Millenniums La Porte, Texas facility, and seeking an unspecified amount of damages. The previously disclosed Texas Commission on Environmental Quality notifications alleging noncompliance of emissions monitoring requirements at
Millenniums La Porte facility and Equistars Channelview facility and seeking civil penalties of $179,520 and $167,000, respectively, have been included as part of this lawsuit. Millennium and Equistar do not believe that the ultimate
resolution of this matter will have a material adverse effect on their respective businesses, financial positions, liquidity or results of operations.

Indemnification

Millennium and its joint ventures are parties to various indemnification
arrangements, including arrangements entered into in connection with acquisitions, divestitures and the formation of joint ventures. For example, Millennium entered into indemnification arrangements in connection with its demerger from Hanson plc,
and Equistar and its owner companies (including Millennium) entered into indemnification arrangements in connection with the formation of Equistar. Pursuant to these arrangements, Millennium and its joint ventures provide indemnification to and/or
receive indemnification from other parties in connection with liabilities that may arise in connection with the transactions and in connection with activities prior to completion of the transactions. These indemnification arrangements typically
include provisions pertaining to third party claims relating to environmental and tax matters and various types of litigation. As of December 31, 2006, Millennium has not accrued any significant amounts for such indemnification obligations and
is not aware of other circumstances that would be likely to lead to significant future indemnification claims against Millennium. Millennium cannot determine with certainty the potential amount of future payments under the indemnification
arrangements until events arise that would trigger a liability under the arrangements.

Millennium does not have a class of equity securities registered pursuant to Section 12 of the
Securities Exchange Act of 1934. There is no established public trading market for the common stock of Millennium. As a result of Lyondells acquisition of Millennium, Millennium is a wholly-owned subsidiary of Lyondell.

Millennium did not pay dividends on its common stock during 2005 and 2006. Millenniums credit facility contains certain
restrictions on Millenniums ability to pay dividends on its common stock. In addition, Millennium is prohibited from paying any dividends under provisions of the 9.25% Senior Notes. For a description of those restrictions, see Item 1A.

|Item 7. | Managements Discussion and Analysis of Financial Condition and Results of Operations
|------- | -------------------------------------------------------------------------------------

This discussion should be read in conjunction with the information contained in the Consolidated Financial Statements of Millennium
Chemicals Inc., together with its consolidated subsidiaries (collectively, Millennium or the Company), and the notes thereto.

In addition to comparisons of annual operating results, Millennium has included, as additional disclosure, certain trailing quarter comparisons of fourth quarter 2006 operating results to third quarter
2006 operating results. Millenniums businesses are highly cyclical, in addition to experiencing some less significant seasonal effects. Trailing quarter comparisons may offer important insight into current business directions.

OVERVIEW

GeneralMillennium, a global manufacturer and marketer of chemicals, primarily titanium dioxide (TiO2) and acetyls, is a wholly-owned subsidiary of Lyondell Chemical Company (Lyondell). Millennium was acquired by Lyondell on November 30, 2004. Millenniums operates in two reportable segments: inorganic
chemicals, which primarily consist of TiO2; and ethylene, co-products and derivatives (EC&D). The
EC&D segment includes Millenniums acetyls business and Millenniums 29.5% interest in Equistar Chemicals, LP (together with its consolidated subsidiaries, Equistar), which is accounted for by Millennium using the equity
method. Other subsidiaries of Lyondell hold the remaining interest in Equistar. On February 23, 2007, Millennium signed an agreement for a proposed sale of Millenniums worldwide inorganic chemicals business for $1.05 billion, in cash, plus the
assumption of specified liabilities. Closing is anticipated to occur in the first half of 2007.

2006 Versus 2005Demand for TiO2in 2006 was negatively affected by a
weaker U.S. housing market during the latter half of the year. During 2006 and 2005, the markets for Equistars ethylene products generally continued to experience favorable supply and demand conditions.

Operating results for the inorganic chemicals segment in 2006 compared to 2005 were negatively affected by higher raw material and
utility costs compared to 2005, as well as by production problems primarily at a plant in the U.K. Compared to 2005, product sales prices in 2006 were moderately higher. The 2005 operating results were negatively affected by inventory reduction
efforts, including reduced plant operating rates, which were initiated in the third quarter 2005 in response to weak 2005 demand.

In 2006 compared to 2005, the acetyls business benefited from higher market sales prices for methanol. Overall raw material and energy costs were higher in 2006 compared to 2005 due to higher average market prices for ethylene, which were
only partly offset by lower average market prices for natural gas.

Millenniums equity investment in Equistar
resulted in 2006 income of $181 million compared to 2005 income of $221 million as Equistars average product margins improved. Equistars results for 2006 included a pretax charge of $135 million, of which Millenniums proportionate
share was $40 million, related to impairment of the net book value of Equistars idled Lake Charles, Louisiana ethylene facility. Equistars operating results for 2006 reflected the benefits of higher sales prices, including significantly
higher co-product and polyethylene sales prices, which were substantially offset by higher costs, primarily higher raw material costs, compared to 2005.

2005 versus 2004The TiO2market experienced weaker demand in 2005 compared to 2004. However, in 2005, the chemical industry generally experienced improved profitability compared to
2004, despite higher crude oil and natural gas prices that pushed up raw material costs for most of the year and the disruptive effects of two major U.S. Gulf Coast hurricanes.

The U.S. Gulf Coast hurricanes, Katrina and Rita, negatively affected crude oil and natural gas supplies, as well as supplies of other raw materials, contributing to the increases in raw material
prices in 2005. Supply/demand balances and prices were affected beginning in September 2005 as most Gulf Coast producers of chemicals suspended operations in preparation for the hurricanes, with some sustaining major damage as a result of the
hurricanes. Millenniums and Equistars Gulf Coast plants experienced only minor hurricane damage; however, they suspended plant operations in preparation for Hurricane Rita, resulting in lost production and higher costs during 2005.

Operating results for the
inorganic chemicals segment in 2005 compared to conditions in 2004 reflected benefits from higher sales prices, offset by the negative effects of weaker TiO2demand. In response to the weaker 2005 demand, Millennium initiated inventory reduction efforts, including reduced 2005 plant operating rates that lowered earnings by approximately $20 million.

The acetyls business was negatively affected in 2005 compared to 2004 by higher raw material and energy costs, due to
higher ethylene and natural gas prices, and lower sales volumes, resulting from weaker demand. These negative effects were only partly offset by the benefits of higher average product sales prices.

Millenniums equity investment in Equistar resulted in 2005 income of $221 million compared to 2004 income of $81 million as
Equistars average product margins improved. The benefit of the higher average product margins was partly offset by the negative effects of hurricane-related costs and lower sales volumes.

RESULTS OF OPERATIONS

RevenuesMillenniums revenues of $1,948 million for 2006 were comparable to 2005 revenues of $1,959 million as lower product sales volumes were substantially offset by higher average sales prices. Acetyls sales
volumes decreased due primarily to a 10% decrease in vinyl acetate monomer (VAM) sales, while TiO2sales
volumes were 4% lower.

Revenues of $1,959 million for 2005
increased 4% compared to $1,888 million in 2004 due to higher acetyls and TiO2sales prices in 2005, partly offset
by the effect of lower sales volumes. Acetyls sales volumes decreased due primarily to a 17% decrease in VAM sales, while TiO2sales volumes were 7% lower.

Cost of SalesMillenniums cost of sales of $1,732 million
in 2006 was comparable to $1,715 million in 2005 as higher production costs, reflecting higher raw material, distribution and utility costs, were substantially offset by the effect of lower sales volumes in 2006 compared to 2005.

Cost of sales of $1,715 million in 2005 increased 7% compared to $1,602 million in 2004, primarily due to rising energy and raw
material costs, particularly natural gas. In 2005, reduced plant operating rates resulting from the inventory reduction program also affected cost of sales negatively. These effects were partly offset by the effect of lower sales volumes in 2005
compared to 2004.

SG&A ExpensesSG&A expenses were $158 million, $194 million and $164 million in
2006, 2005 and 2004, respectively. The 19% decrease in SG&A expenses in 2006 compared to 2005 was principally due to lower provisions for environmental remediation costs. Higher compensation and employee benefit costs in 2006 were substantially
offset by lower legal expenses and other costs compared to 2005. The 18% increase in SG&A expenses in 2005 compared to 2004 was primarily due to legal services and estimated environmental remediation costs.

Business Combination CostsThe decrease of $69 million in business combination costs from 2004 to 2005 was the result of
Millennium incurring $71 million of business combination costs in connection with Lyondells November 30, 2004 acquisition of Millennium, which costs primarily consisted of change-of-control liabilities to officers and key employees of
Millennium and the vesting of certain of their benefits in 2004, compared to only $2 million in 2005.

Asset ImpairmentsMillenniums asset impairment charges of $22 million in 2006, $15 million in 2005, and $14 million in 2004 reflected impairments of capital expenditures
for Millenniums Le Havre, France TiO2manufacturing facility as well as, in 2006, $7 million of certain
software costs. See Note 5 to the Consolidated Financial Statements.

Operating IncomeMillennium had operating
income of $8 million in 2006 compared to $10 million in 2005. The combined effects of higher raw material and energy costs, plant operating problems, primarily in the U.K., and lower sales volumes were substantially offset by $36 million
of lower environmental remediation costs in 2006 compared to 2005.

##### Index to Financial Statements

Millennium had operating income of $10 million in 2005 compared to $7 million
in 2004. The increase in 2005 compared to 2004 was primarily the result of a $69 million decrease in business combination costs, which was substantially offset by $30 million of higher legal costs and provisions for estimated environmental
remediation costs and lower product margins. The lower product margins in 2005 reflected the effect of higher energy and raw material costs, which were only partially offset by higher average sales prices compared to 2004.

Interest ExpenseInterest expense was $78 million in 2006, $130 million in 2005 and $106 million in 2004. Interest
expense in 2005 included $29 million of interest associated with income tax issues. The remaining decrease in 2006 of $23 million reflected net repayments of debt of $541 million since January 1, 2005. See the Financing
Activities section of Financial Condition below for a description of the issuance and repayment of debt during 2005 and 2006.

Other Income (Expense), netMillennium had $24 million of other income, net, in 2006, $19 million of other expense, net, in 2005 and other income, net, of $14 million in 2004. Other income, net, in
2006 included a net benefit of $29 million related to the reversal of interest expense accruals as a result of a favorable settlement of prior year income tax issues, partially offset by a $7 million charge for debt prepayment premiums.
Other expense, net, in 2005 included $10 million of debt prepayment premiums and $9 million of charges related to other investments. Other income, net, in 2004 included $6 million related to the reversal of interest expense accruals as a result of
the favorable settlement of tax issues.

Income from Equity Investment in EquistarMillenniums equity
investment in Equistar resulted in income of $181 million, $221 million and $81 million in 2006, 2005 and 2004, respectively. See Note 7 to the Consolidated Financial Statements. Equistars operating results are reviewed in the discussion
of the EC&D segment below.

Income TaxesMillennium had an income tax benefit of $19 million in 2006
and tax provisions of $67 million and $33 million in 2005 and 2004, respectively. The $19 million tax benefit on income before tax and minority interest of $142 million primarily reflected the $80 million effect of favorable
settlements of and changes in estimates for prior year items during 2006, partly offset by an $18 million increase in the valuation allowance for tax assets of French subsidiaries. The $67 million provision in 2005 exceeded the U.S. statutory
rate due primarily to a $13 million increase in estimates of taxes for prior years and a $16 million increase in the valuation allowance for tax assets of French subsidiaries. The $33 million provision in 2004 exceeded the U.S. statutory rate,
reflecting an increase of $28 million in estimates of taxes for prior years and a $20 million increase in the valuation allowance for tax assets of French subsidiaries.

Net IncomeMillennium reported net income of $159 million and $28 million in 2006 and 2005, respectively, and a net loss of $31 million in 2004. The $131 million increase in
profitability in 2006 compared to 2005 reflected a $102 million benefit from income tax effects and after-tax increases of $28 million in other income (expense), net, and $27 million in interest expense, net, all of which were partially
offset by after-tax decreases of $26 million in income from Millenniums equity investment in Equistar. Operating income in 2006 was comparable to 2005. The $59 million improvement in 2005 compared to 2004 was primarily the result of
the increase in income from Millenniums equity investment in Equistar of $91 million after tax and a decrease in business combination costs of $45 million after tax. These improvements were partly offset by the increases in SG&A, interest
expense and other expense, net, noted above, totaling $45 million after tax, and the after-tax effect of lower sales volumes of approximately $30 million in 2005 compared to 2004.

Fourth Quarter 2006 versus Third Quarter 2006Millennium had a net loss of $5 million in the fourth quarter 2006
compared to net income of $17 million in the third quarter 2006. The decrease in the fourth quarter 2006 reflected after-tax decreases of $24 million in operating income and $12 million attributable to income tax effects, partially
offset by an after-tax increase of $14 million in income from its equity investment in Equistar. Millenniums third quarter 2006 income from its equity investment in Equistar included its $26 million after tax proportionate share of
Equistars pretax impairment charge of $135 million. The remaining decrease in Equistars fourth quarter 2006 results compared to the third quarter 2006 was due to lower margins and the effect of lower sales volumes.

Segment Analysis

Millenniums principal operations are grouped into two business segments: inorganic chemicals; and EC&D. The EC&D segment includes Millenniums acetyls business and
Millenniums 29.5% interest in Equistar, which is accounted for under the equity method. See Note 7 to the Consolidated Financial Statements.

The following table reflects summarized financial information for Millenniums segments. Other operating loss includes income and expense not identified with the two businesses, including certain of
Millenniums SG&A expenses, business combination costs and employee-related costs from predecessor businesses.

Inorganic Chemicals Segment

OverviewThe Inorganic Chemicals (Inorganics) segment
primarily produces TiO2, but also produces titanium tetrachloride (TiCl4), titanyl sulfate (TiOSO4), ultra-fine TiO2and other inorganic chemicals. On February 23, 2007, Millennium
signed an agreement for a proposed sale of Millenniums worldwide inorganic chemicals business (See Note 22 to the Consolidated Financial Statements).

Operating results for the Inorganics segment included pretax asset impairment
charges of $22 million in 2006, $15 million in 2005 and $14 million in 2004 associated with the write-down of property, plant and equipment at the Le Havre, France TiO2manufacturing facility as well as, in 2006, certain software costs.

RevenuesRevenues of $1,354 million in 2006 were comparable to revenues of $1,360 million in 2005. Revenues in 2006 reflected the effects of 4% higher average U.S. dollar
sales prices that were offset by the effect of 4% lower sales volumes compared to 2005. Sales volumes in 2006 were lower compared to 2005 as a result of lower U.S. demand and production problems, primarily at a U.K. plant.

Revenues of $1,360 million in 2005 were comparable to revenues of $1,340 million
in 2004 as 9% higher average sales prices were substantially offset by the effect of 7% lower sales volumes. Sales volumes were lower in 2005 despite the positive effect of hurricane-related supply disruptions at another TiO2producers facility during part of 2005. The lower 2005 sales volumes compared to 2004 reflected weaker 2005 demand and
Millenniums 2004 efforts to reduce inventory levels through a strong sales volume push.

Operating IncomeThe Inorganics segment had an operating loss of
$2 million in 2006 compared to operating income of $24 million in 2005. The $26 million decrease was primarily attributable to approximately $25 million of higher production costs, reflecting higher raw material, distribution and
energy costs and the effects of operating problems, primarily in the U.K., the $13 million effect of lower product sales volumes and a $7 million charge for impairment of certain software costs, all of which were partially offset by the
$20 million effect of higher average U.S. dollar sales prices compared to 2005.

The Inorganics segment had operating income of $24 million in 2005 compared to $51 million in 2004. The decrease in operating income reflected the negative effect of lower sales volumes of approximately $15 million
and a $15 million provision for estimated environmental remediation costs. Product margins were relatively unchanged as higher product sales prices substantially offset the negative effects of lower sales volumes as a result of weaker
TiO2demand. In response to the weaker 2005 demand, Millennium initiated inventory reduction efforts, including
reduced 2005 plant operating rates.

Ethylene, Co-products and Derivatives Segment

Millenniums EC&D segment comprises its wholly-owned acetyls business and its equity investment in Equistar.

Acetyls Business

OverviewThe acetyls business produces and markets VAM, acetic acid and methanol.

RevenuesAcetyls revenues of $481 million in 2006 were 5% lower compared to revenues of $504 million in 2005, primarily due to lower sales volumes, partially offset by the effects of higher average sales prices. The
decrease in sales volumes in 2006 compared to 2005 primarily reflected 10% lower sales volumes for VAM reflecting lower sales to U.S. and Asian markets. The increase in average sales prices was primarily due to higher average sales prices for
methanol.

Acetyls revenues of $504 million in 2005 increased by $51 million, or 11%, compared to revenues of
$453 million in 2004 primarily due to higher average sales prices, which were partly offset by lower sales volumes. In 2005, the aggregate sales price for VAM and acetic acid was 17% higher than in 2004 as price increases were implemented in
response to higher raw material and energy costs. The sales volume decrease in 2005 compared to 2004 primarily reflected lower VAM sales volumes.

Operating IncomeOperating income was $36 million in 2006 compared to $45 million in 2005. The $9 million decrease was primarily due to lower margins, which reflected $39 million of
higher costs, partially offset by the $34 million effect of higher average sales prices. The higher costs were primarily due to higher raw material costs reflecting an increase in ethylene prices, partially offset by the benefit of lower
natural gas prices. Lower sales volumes in 2006 had a $4 million negative effect.

The acetyls business had operating
income of $45 million in 2005 compared to operating income of $59 million in 2004. The $14 million decrease was primarily due to higher raw material and energy costs of approximately $90 million and the effect of lower sales volumes of
approximately $10 million, partially offset by approximately $85 million of higher sales prices.

Equity Investment in Equistar

OverviewEquistar manufactures and markets ethylene and its co-products, primarily propylene, butadiene and aromatics, which
include benzene and toluene. Equistar also manufactures and markets ethylene derivatives, primarily polyethylene (including high density polyethylene (HDPE), low density polyethylene (LDPE) and linear-low density polyethylene
(LLDPE)), ethylene glycol, ethylene oxide (EO) and other EO derivatives, and ethanol. Equistar also manufactures and markets fuel products, such as methyl tertiary butyl ether (MTBE) and alkylate, as well as
polypropylene. As a result of the acquisition of Millennium by Lyondell on November 30, 2004, Equistar became a wholly-owned subsidiary of Lyondell.

2006 Versus 2005During 2006 and 2005, the markets for Equistars ethylene products generally continued to experience favorable supply and demand conditions. Raw material costs averaged higher in 2006
compared to the already high levels experienced in 2005, resulting primarily from the effect of higher average crude oil prices. Despite increased volatility during 2006 and a decrease late in the year, crude oil prices averaged higher in 2006
compared to 2005. U.S. market demand increased an estimated 5% for ethylene and an estimated 5% for polyethylene in 2006 compared to 2005.

Equistars operating results for 2006 reflected the benefits of higher sales prices, including significantly higher co-product and polyethylene sales prices, which were substantially offset by higher costs,
primarily higher raw material costs, compared to 2005. Results for 2006 included a charge of $135 million related to impairment of the net book value of the idled Lake Charles, Louisiana ethylene facility.

2005 Versus 2004In 2005, the chemical industry experienced improved profitability compared to 2004, despite higher crude oil
and natural gas prices that pushed up raw material costs for most of the year and the disruptive effects of two major U.S. Gulf Coast hurricanes. Improvement in supply and demand balances, which began in mid-2004 continued into 2005. Tight gasoline
markets in 2005 resulted in higher sales prices and margins for fuel products compared to the already high levels experienced in 2004. U.S. ethylene industry demand decreased 6% and polyethylene demand decreased 4% in 2005 compared to 2004, due
primarily to the effects of the U.S. Gulf Coast hurricanes.

The U.S. Gulf Coast hurricanes, Katrina and Rita, negatively
affected crude oil and natural gas supplies, as well as supplies of other raw materials, contributing to the increases in raw material prices in 2005. Supply/demand balances and prices were affected beginning in September 2005 as most Gulf Coast
refiners and producers of chemicals suspended operations in preparation for the hurricanes, with some sustaining major damage as a result of the hurricanes. Equistars Gulf Coast plants experienced only minor hurricane damage; however, Equistar
suspended plant operations in preparation for Hurricane Rita, resulting in lost production and higher costs during 2005.

Equistars earnings in 2005 reflected higher average product margins compared to 2004, partly offset by the negative effects of hurricane-related costs and lower sales volumes.

Benchmark IndicatorsBenchmark crude oil and natural gas prices generally have been indicators of the level and direction of
movement of raw material and energy costs for Equistar. Ethylene and its co-products are produced from two major raw material groups:



| |  |  | crude oil-based liquids (liquids or heavy liquids), including naphthas, condensates, and gas oils, the prices of which are generally
related to crude oil prices; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | natural gas liquids (NGLs), principally ethane and propane, the prices of which are generally affected by natural gas prices.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------

Equistar has the ability to shift its ratio of raw materials used in the production of ethylene and
co-products to take advantage of the relative costs of heavy liquids and NGLs.

The following table shows the average U.S. benchmark prices for crude oil and natural gas
for the applicable three-year period, as well as benchmark U.S. sales prices for ethylene, propylene, benzene and HDPE, which Equistar produces and sells. The benchmark weighted average cost of ethylene production, which is reduced by co-product
revenues, is based on CMAIs estimated ratio of heavy liquid raw materials and NGLs used in U.S. ethylene production and is subject to revision.

Although benchmark crude oil prices decreased late in 2006, benchmark crude oil
prices averaged higher in 2006 compared to 2005 and averaged significantly higher in 2005 compared to 2004.Natural gas prices, which affect energy costs in addition to NGL-based raw materials, averaged lower in 2006 compared to 2005, and
averaged significantly higher in 2005 compared to 2004. Despite the 2006 decrease in natural gas prices, NGL-based raw material prices averaged higher in 2006 than in 2005. As a result, overall raw material costs averaged higher in 2006 compared to
2005 and significantly higher in 2005 compared to 2004.

RevenuesEquistars revenues of
$12,765 million in 2006 were 9% higher compared to revenues of $11,686 million in 2005. The higher revenues in 2006 reflected the effects of higher average sales prices compared to 2005. Sales volumes increased 2% in 2006 compared to 2005.

Revenues of $11,686 million in 2005 increased 25% compared to revenues of $9,316 million in 2004. The increase in 2005
reflected higher average sales prices, partially offset by lower sales volumes. As noted in the table above, benchmark sales prices for ethylene, propylene and HDPE averaged significantly higher in 2005 compared to 2004, while benzene average sales
prices in 2005 were comparable to 2004. Ethylene and derivative sales volumes were 5% lower in 2005 compared to 2004.

Net IncomeEquistar had net income of $614 million in 2006 compared to $748 million in 2005. The decrease was primarily attributable to the $135 million impairment charge. Operationally, higher 2006 sales prices
were substantially offset by higher costs, primarily higher raw material costs.

Equistar had net income of $748 million in
2005 compared to $276 million in 2004. The $472 million improvement was primarily the result of higher average product margins. The benefit of the higher 2005 average product margins was partly offset by the negative effects of hurricane-related
costs and lower sales volumes. Hurricane-related costs included $20 million of charges, representing Equistars exposure to industry losses expected to be underwritten by industry insurance consortia, and $19 million of costs incurred in
conjunction with suspending and restarting operations.

Other

Other operations include Millenniums flavors and fragrances business, and unallocated operating expenses that are not identified with the reportable business segments.

Other operating losses were $26 million in 2006, $59 million in 2005 and $103 million in 2004. Other operating losses in 2006
included $12 million of accruals for estimated environmental remediation costs and in 2005 included $43 million of accruals for estimated environmental remediation costs and $13 million of charges related to other investments. The 2004 amount
included $71 million of business combination costs, $31 million of accruals for estimated environmental remediation costs and $3 million of reorganization costs.

FINANCIAL CONDITION

Operating ActivitiesOperating activities provided cash of
$193 million in 2006, $275 million in 2005 and $195 million in 2004, respectively. The $82 million decrease in 2006 compared to 2005 was primarily due to increased cash usage related to the main components of working capital  accounts
receivable and inventories, net of accounts payableand $44 million of lower distributions of earnings from Equistar. Although higher compared to 2005, net income in 2006 included reversals of previous tax-related liabilities, which did not
provide cash.

A net increase in the main components of working capital used cash of $16 million in 2006 compared to a net
decrease in 2005 that provided cash of $29 million. The increase in 2006 was primarily due to a $50 million increase in cash used by accounts payable, partially offset by a $28 million decrease in cash used by accounts receivable. The cash used
to reduce accounts payable primarily reflected the timing of payments for shared services provided by Equistar. The decrease in accounts receivable reflected lower sales volumes late in 2006 compared to the same period in 2005.

The $80 million improvement in operating cash flow in 2005 compared to 2004 was primarily due to $133 million of higher
distributions of earnings from Equistar and reductions in the main components of working capital  accounts receivable and inventory, net of accounts payable - partly offset by the effects of lower 2005 earnings at Millennium. The main
components of working capital decreased, providing cash of $29 million in 2005, primarily due to a $77 million increase in accounts payable, which reflected higher raw material and energy prices in December 2005.

Investing ActivitiesInvesting activities used cash of $65 million in 2006, $60 million in 2005 and $41 million in 2004,
primarily reflecting Millenniums capital expenditures. In addition, in 2004, Millennium received $12 million of distributions in excess of earnings from Equistar.

Capital expenditures were $66 million in 2006, $60 million in 2005 and $55 million in 2004. Millenniums capital expenditures for this three-year period primarily included replacement
capital projects and certain environmental, cost reduction, and yield-improvement projects. Planned capital spending in 2007 is projected to be approximately $78 million, primarily for base asset support and projects to improve manufacturing
efficiency.

Financing ActivitiesFinancing activities used cash of $290 million in 2006, $272 million in 2005
and $38 million in 2004, primarily for debt repayment. Millennium intends to continue to reduce its indebtedness as market conditions permit.

In 2006, Millennium purchased $158 million principal amount of its 7% Senior Notes due 2006, paying a premium of $2 million, and purchased $85 million principal amount of 9.25% Senior Notes due 2008,
paying a premium of $5 million. Other reductions of debt in 2006 totaled $39 million of principal, including $29 million principal amount of the Australian term loan.

During 2006, a U.K. subsidiary of Millennium entered into a new 60 million, five-year, revolving credit facility. There were
no amounts outstanding at December 31, 2006. See Liquidity and Capital Resources.

In 2005, Millennium purchased $342 million principal amount of its 7% Senior Notes due
2006, $13 million of the 9.25% Senior Notes due 2008 and $1 million of the 7.625% Senior Debentures due 2026, paying a total premium of $10 million. See Liquidity and Capital Resources below regarding the May 2005 credit facility
amendment, which permitted the purchases, and other amendments to the Millennium credit facility. Additionally in 2005, Millennium paid a cash dividend totaling $6 million to minority interests during 2005 and received a contribution of $6 million
from Lyondell.

In August 2005, Millennium amended and restated its $150 million credit facility, replacing it with a
$125 million U.S. revolving credit facility, a $25 million Australian revolving credit facility, and a $100 million Australian senior term loan, all of which mature in August 2010. See Liquidity and Capital Resources below for a
description of availability under the new credit facilities. The U.S. revolving credit facility and the Australian revolving credit facility are used for liquidity and general corporate purposes. The Australian term loan facilitated the repatriation
of non-U.S. earnings and returns of investment that were primarily used to reduce Millennium indebtedness as discussed below.

Pursuant to the indenture governing the 9.25% Senior Notes, Millennium was required to purchase $4 million principal amount of its 9.25% Senior Notes and pay a 1% premium as a result of Lyondells acquisition of Millennium on
November 30, 2004.

In 2004 cash was used to prepay $55 million of debt, and cash proceeds from stock option exercises
were $17 million.

Liquidity and Capital ResourcesMillenniums balance sheet remains highly levered.
As of December 31, 2006, total debt, including current maturities, was $853 million, or 82% of total capitalization. At December 31, 2006, Millennium had $121 million of cash on hand and $189 million of unused availability under
its revolving credit facilities as follows:



| |  |  | $128 million in total under Millenniums $125 million U.S. and $25 million Australian secured revolving credit facilities, which mature in
August 2010. Availability under the revolving credit facilities is reduced to the extent of outstanding letters of credit provided under the facilities. Letters of credit outstanding under the $125 million U.S. revolving credit facility at
December 31, 2006 totaled $22 million. At December 31, 2006, there were no outstanding letters of credit under the $25 million Australian revolving credit facility, and there was no outstanding borrowing under either revolving
credit facility.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | 46 million, or approximately $61 million, under Millenniums 60 million, five-year, U.K. revolving credit facility. Availability under
the facility gives effect to the borrowing base, as determined using a formula applied to accounts receivable and inventory balances, and is reduced to the extent of outstanding borrowing, and letters of credit provided under the facility. At
December 31, 2006, there was no outstanding borrowing, and there were no outstanding letters of credit under the revolving credit facility.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In addition to letters of credit outstanding under the U.S. revolving credit facility, Millennium had other outstanding letters of credit and bank guarantees under other arrangements of
$8 million at December 31, 2006.

Historically, Millennium has financed its operations primarily through cash
generated from its operations, cash distributions from Equistar, and debt financing. Cash generated from operations is, to a large extent, dependent on economic, financial, competitive and other factors affecting Millenniums and
Equistars businesses. The amount of cash distributions received from Equistar is affected by Equistars results of operations and current and expected future cash flow requirements. Some of Equistars indentures require additional
interest payments to the note holders if Equistar makes distributions when its Fixed Charge Coverage Ratio, as defined, is less than 1.75 to 1. Millennium received $170 million, $214 million and $93 million, respectively, of distributions from
Equistar during 2006, 2005 and 2004.

Millenniums ability to pay or refinance its debt also may depend on future
operating performance, which could be affected by general economic, financial, competitive, legislative, regulatory, business and other factors, many of which are beyond its control. However, Millennium believes that conditions will be such that
cash balances, cash generated from operating activities, cash distributions from Equistar and funds from lines of credit will be adequate to meet anticipated future cash requirements, including scheduled debt repayments, necessary capital
expenditures and ongoing operations.

On February 23, 2007, Millennium signed an agreement for a proposed sale of
Millenniums worldwide inorganic chemicals business for $1.05 billion, in cash, plus the assumption of specified liabilities. Closing is anticipated to occur in the first half of 2007.

In June 2006, Standard & Poors Rating Services (S&P) lowered its ratings for Millennium from BB- to B+
with a negative outlook following the February 2006 Rhode Island jury verdict against a Millennium subsidiary, Millennium Holdings, LLC, and other defendants. See the Litigation section of Note 18 to the Consolidated Financial
Statements. In June 2006, Moodys Investors Service (Moodys) reinstated Millenniums debt ratings at Ba3 and, in July 2006, Moodys placed the ratings of Millennium under review for possible downgrade. In September
2006, Moodys confirmed the rating of Millennium and revised its outlook for Millennium to stable, reflecting Moodys belief that the additional debt incurred in connection with the Houston Refining LP acquisition by Lyondell will be
reduced over the next several years using anticipated increased refining cash flow.

In May 2006, Millennium amended its
senior secured revolving credit facilities and, in July 2006, amended the indenture governing its 4% Convertible Senior Debentures primarily to exclude a subsidiary of Millennium, Millennium Holdings, LLC, and its subsidiaries (collectively
Millennium Holdings) from events-of-default provisions that could be triggered in connection with judgments against Millennium Holdings. In August 2005, Millennium amended and restated its $150 million credit facility, as described
above.

In May 2005, Millennium obtained an amendment to its previous $150 million credit facility to allow for the
unrestricted repurchase of indebtedness in the form of bonds, debentures, notes, or similar instruments. On February 2, 2005, as a result of certain adjustments and charges related to the February 2005 restatement of Millenniums financial
statements, Millennium entered into an amendment and waiver to its previous $150 million credit facility, which amended the credit facility definition of EBITDA and waived any and all defaults or events of default that may have occurred on or prior
to the amendment and waiver.

Millenniums facilities and its indentures contain restrictive covenants. Pursuant to
these provisions, Millennium is currently prohibited from making restricted payments, including paying certain dividends. Other than the U.K. facility, Millenniums facilities also contain covenants that require the maintenance of specified
financial ratios. These covenants, as well as debt guarantees, are described in Note 13 to the Consolidated Financial Statements. The potential impact of a breach of these covenants is discussed below. Millenniums U.K. facility does not
require the maintenance of specified financial ratios as long as certain conditions are met.

A breach by Millennium of any
of the covenants or other requirements in its debt instruments could (1) permit the note holders or lenders to declare the outstanding debt under the breached debt instrument due and payable, (2) permit the lenders under that credit
facility to terminate future lending commitments and (3) permit acceleration of Millenniums other debt instruments that contain cross-default or cross-acceleration provisions. The debt agreements of Millennium contain various event of
default and cross-default provisions. If Millennium was unable to obtain sufficient funds to make these accelerated payments, Millenniums lenders could proceed against any assets that secure their debt.

Millennium has outstanding $150 million aggregate principal amount of 4% Convertible
Senior Debentures, which are due in 2023, unless earlier redeemed, converted or repurchased. As a result of Lyondells acquisition of Millennium, the Debentures are convertible into shares of Lyondells common stock or, at Lyondells
discretion, equivalent cash or a combination thereof. As of December 31, 2006, based on a quarterly test related to the price of Lyondell common stock, the Debentures were convertible at a conversion rate of 74.758 Lyondell shares per one
thousand dollar principal amount of the Debentures. As of December 31, 2006, the amount of the Debentures converted into shares of Lyondell common stock was not significant. The Debenture redemption terms are described in Note 13 to the
Consolidated Financial Statements.

Future Tax ObligationsCertain income tax returns for Millenniums
U.S. and non-U.S. subsidiaries are currently under examination by the Internal Revenue Service (IRS), and various other tax authorities. In many cases, these audits result in proposed assessments by the tax authority. Millennium believes
that its tax positions comply with applicable tax law and intends to defend its positions through appropriate administrative and judicial processes. Millennium believes it has adequately provided for any probable outcome related to these matters,
and does not anticipate any material adverse effect on its financial position or results of operations from their ultimate resolution. During 2006, certain income tax returns and related liabilities under examination by Her Majestys Revenue
and Customs (formerly Inland Revenue) of the U.K., representing approximately $50 million of taxes at issue, were satisfactorily resolved. However, the settlement of one or more remaining tax matters could require substantial cash payments
during the next twelve to eighteen months.

Off-Balance Sheet ArrangementsThe Securities and Exchange
Commission (SEC) has described various characteristics to identify contractual arrangements that would fall within the SECs definition of off-balance sheet arrangements. Millennium is not a party to any such contractual
arrangements.

Other obligations that do not give rise to liabilities that would be reflected in Millenniums balance
sheet are described below under Purchase Obligations and Operating Leases.

Contractual and
Other ObligationsThe following table summarizes as of December 31, 2006, Millenniums minimum payments for long-term debt, and contractual and other obligations for the next five years and thereafter.

Long-Term DebtMillenniums long term debt includes credit
facilities and debt obligations. See Note 13 to the Consolidated Financial Statements for a discussion of covenant requirements under the credit facilities and indentures and additional information regarding long-term debt.

##### Index to Financial Statements

InterestThe long-term debt agreements contain provisions for the payment of
either monthly or semi-annual interest at a stated rate of interest over the term of the debt. These payment obligations are reflected in the table above.

Pension BenefitsMillennium maintains several defined benefit pension plans as described in Note 16 to the Consolidated Financial Statements. At December 31, 2006, the projected benefit obligation for
Millenniums pension plans exceeded the fair value of plan assets by $175 million. Subject to future actuarial gains and losses, as well as actual asset earnings, Millennium, together with its consolidated subsidiaries, will be required to fund
the $175 million, with interest, in future years. Millenniums pension contributions were $24 million, $28 million and $15 million for the years 2006, 2005 and 2004, respectively, and are expected to be approximately $35 million for 2007.
Estimates of pension benefit payments through 2011 are included in the table above.

Pension expense for 2006, 2005 and
2004 was $39 million, $32 million and $30 million, respectively. The 2004 pension expense included $13 million of curtailment charges, resulting from severances subsequent to Lyondells acquisition of Millennium in 2004. Pension expense
increased in 2006 due to a reduction in the discount rate assumption related to Millenniums pension plans and the amortized recognition of pension fund investment losses in the financial markets in recent years prior to 2003.

Other Postretirement BenefitsMillennium provides other postretirement benefits, as described in Note 16 to the Consolidated
Financial Statements. Other postretirement benefits are unfunded and are paid by Millennium as incurred.

As a result of
rising medical benefit costs and competitive business conditions, effective April 1, 2004 Millennium reduced the level of retiree medical benefits provided to essentially all of its retirees by offering a monthly subsidy in 2004 to retirees
that enrolled in designated preferred provider organization plans or Medicare supplement insurance plans. This change reduced Millenniums accumulated postretirement benefit obligation by approximately $48 million. This reduction is being
recognized ratably over approximately thirteen years through the postretirement net periodic benefit cost. Estimates of other postretirement benefit payments through 2011 are included in the table above.

OtherOther primarily consists of liabilities for environmental remediation, deferred compensation arrangements and accrued
liabilities for the resolution of probable tax assessments. The timing of payments of the latter is subject to considerable uncertainty.

Deferred Income TaxesThe scheduled settlement of the deferred tax liabilities shown in the table is based on the scheduled reversal of the underlying temporary differences, all of which would be fully
offset during the first five years by Millenniums tax loss carry forwards. Actual cash tax payments will vary depending upon future taxable income.

Purchase ObligationsIn the ordinary course of business, Millennium enters into contractual obligations to purchase raw materials, utilities and services for fixed or minimum amounts. See the
Commitments section of Note 18 to the Consolidated Financial Statements for a description of Millenniums commitments and contingencies, including these purchase obligations.

Operating LeasesMillennium leases various facilities and equipment under noncancelable lease arrangements for various
periods. See Note 14 to the Consolidated Financial Statements for related lease disclosures.

Equistar Liquidity and
Capital ResourcesAt December 31, 2006, Equistars long-term debt totaled $2.2 billion, or approximately 57% of its total capitalization, and there were no current maturities. At December 31, 2006, Equistar had cash on
hand of $133 million and the total amount available under both the $400 million inventory-based revolving credit facility and the $600 million accounts receivable sales facility totaled approximately $938 million, after giving effect to the
borrowing base net of a $50 million unused availability requirement, any outstanding amount of accounts receivable sold under the accounts receivable sales facility, of which there was none at December 31, 2006, and $12 million of outstanding
letters of credit under the revolving credit facility as of December 31, 2006. The borrowing base is determined using a formula applied to accounts

receivable and inventory balances. The revolving credit facility requires that the unused available amounts under that facility and the $600 million accounts
receivable sales facility equal or exceed $50 million, or $100 million if the Interest Coverage Ratio, as defined, at the end of any period of four consecutive fiscal quarters is less than 2:1. There was no outstanding borrowing under the revolving
credit facility at December 31, 2006.

Equistars ability to continue to pay or refinance its debt will depend on
future operating performance, which could be affected by general economic, financial, competitive, legislative, regulatory, business and other factors, many of which are beyond its control. However, Equistar believes that conditions will be such
that cash balances, cash generated from operating activities, cash generated from higher utilization of the accounts receivable sales facility and funding under the credit facility will be adequate to meet anticipated future cash requirements,
including scheduled debt repayments, necessary capital expenditures and ongoing operations.

In August 2006, S&P
removed Equistars ratings from CreditWatch and revised its outlook to stable, reflecting S&Ps belief that the intermediate-range benefits of the Houston Refining LP acquisition by Lyondell will outweigh the temporary increase in debt
leverage. In September 2006, Moodys confirmed the rating of Equistar and revised its outlook for Equistar to stable, reflecting Moodys belief that the additional debt incurred in connection with the Houston Refining LP acquisition by
Lyondell will be reduced over the next several years using anticipated increased refining cash flow.

Equistars
inventory-based revolving credit facility, accounts receivable sales facility and indentures contain restrictive covenants. These covenants are described in Notes 6 and 12 to Equistars Consolidated Financial Statements included in
Equistars Annual Report on Form 10-K for the year ended December 31, 2006. The potential impact of a breach of these covenants is discussed in Liquidity and Capital Resources under Item 7 of Equistars Annual Report
on Form 10-K for the year ended December 31, 2006. The credit facility does not require the maintenance of specified financial ratios as long as certain conditions are met. Some of Equistars indentures require additional interest payments
to the note holders if Equistar makes distributions when its Fixed Charge Coverage Ratio, as defined, is less than 1.75 to 1.

CURRENT BUSINESS OUTLOOK

For Millenniums inorganic chemicals segment, first quarter
2007 operations and order volumes have improved versus the fourth quarter 2006. Thus far in 2007, the inorganic chemicals segment has benefited from the correction of the 2006 operating problems. For the EC&D segment, underlying business
fundamentals continue to be sound thus far in 2007. For 2007, fundamental supply and demand conditions for the EC&D segments products should be relatively unchanged from the favorable conditions experienced in 2006.

RELATED PARTY TRANSACTIONS

In view of Occidental Petroleum Corporations (together with
its subsidiaries and affiliates, collectively Occidental) relationship with Lyondell, which owns 100% of Millennium as a result of the acquisition on November 30, 2004, Occidentals transactions with Millennium are reported as
related party transactions in Millenniums Consolidated Financial Statements.

Millennium purchases products from
Equistar, a joint venture with Lyondell, and Occidental at market-related prices and, sells products to Equistar and Lyondell at market-based prices. As a result of the acquisition of Millennium by Lyondell on November 30, 2004, Millennium and
Lyondell entered into an agreement for the provision of administrative services by Lyondell to Millennium, as well as a tax-sharing agreement.

Millennium believes that such transactions are effected on terms substantially no more or less favorable than those that would have been agreed upon by unrelated parties on an arms length basis. See Note 6 to
the Consolidated Financial Statements for further discussion of related party transactions.

CRITICAL ACCOUNTING POLICIES

Millennium applies those accounting policies that management
believes best reflect the underlying business and economic events, consistent with accounting principles generally accepted in the U.S. Millenniums more critical accounting policies include those related to liabilities for anticipated
expenditures to comply with environmental regulations, accruals for taxes based on income, the equity interest in Equistar, long-lived assets, including the costs of major maintenance turnarounds and repairs, the valuation of goodwill, and accruals
for long-term employee benefit costs such as pension and postretirement costs. Inherent in such policies are certain key assumptions and estimates made by management. Management periodically updates its estimates used in the preparation of the
financial statements based on its latest assessment of the current and projected business and general economic environment. These critical accounting policies have been discussed with Millenniums Board of Directors. Millenniums
significant accounting policies are summarized in Note 2 to the Consolidated Financial Statements.

Liabilities for
Environmental Remediation CostsAnticipated expenditures related to investigation and remediation of contaminated sites, which include current and former plant sites and other remediation sites, are accrued when it is probable a liability
has been incurred and the amount of the liability can be reasonably estimated. Only ongoing operating and monitoring costs, the timing of which can be determined with reasonable certainty are discounted to present value. Future legal costs
associated with such matters, which generally are not estimable, are not included in these liabilities.

As of
December 31, 2006, Millenniums accrued liability for future environmental remediation costs at current and former plant sites and other remediation sites totaled $172 million. The liabilities for individual sites range from less than $1
million to $106 million, and remediation expenditures are expected to occur over a number of years, and not to be concentrated in any single year. In the opinion of management, there is no material estimable range of reasonably possible loss in
excess of the liabilities recorded for environmental remediation. However, it is possible that new information about the sites for which the accrual has been established, new technology or future developments such as involvement in investigations by
regulatory agencies, could require Millennium to reassess its potential exposure related to environmental matters. See Note 18 to the Consolidated Financial Statements for further discussion of environmental remediation matters.

Accruals for Taxes Based on IncomeUncertainties exist with respect to interpretation of complex U.S. federal and non-U.S.
tax regulations. Management expects that Millenniums interpretations will prevail. Also, Millennium has recognized deferred tax benefits relating to its future utilization of past operating losses. Millennium believes it is more likely than
not that the amounts of deferred tax assets in excess of the related valuation reserves will be realized. Further details on Millenniums income taxes appear in Note 17 to the Consolidated Financial Statements.

Equity Interest in EquistarMillennium has evaluated the carrying value of its investment in Equistar at December 31,
2006 using fair value estimates prepared by Lyondell in connection with Lyondells accounting for its acquisition of Millennium, and by third parties. Based on those estimates, Millennium has determined that the fair value exceeded
Millenniums carrying value for its Equistar investment. The carrying value of Millenniums investment in Equistar at December 31, 2006 was $470 million. If future valuation estimates for Millenniums interest in Equistar
are lower than Millenniums carrying value for its interest in Equistar, an adjustment to write down the investment would be required.

Long-Lived AssetsWith respect to long-lived assets, key assumptions
include the estimates of useful asset lives and the recoverability of carrying values of fixed assets and other intangible assets, as well as the existence of any obligations associated with the retirement of fixed assets. Such estimates could be
significantly modified and/or the carrying values of the assets could be impaired by such factors as new technological developments, new chemical industry entrants with significant raw material or other cost advantages, uncertainties associated with
the U.S. and world economies, the cyclical nature of the chemical and refining industries, and uncertainties associated with governmental actions. Impairments were recorded in each of the years 2006, 2005 and 2004 for the LeHavre, France,
TiO2facility and in 2006 for certain software costs.

##### Index to Financial Statements

The estimated useful lives of long-lived assets range from 5 to 40 years. Depreciation
and amortization of these assets, including amortization of deferred turnaround costs, under the straight-line method over their estimated useful lives totaled $101 million, $107 million and $114 million in 2006, 2005 and 2004, respectively. If
the useful lives of the assets were found to be shorter than originally estimated, depreciation and amortization charges would be accelerated over the revised useful life.

Millennium defers the costs of major periodic maintenance and repair activities (turnarounds) amortizing such costs over the period until the next expected major turnaround of the
affected unit. During 2006, 2005 and 2004, cash expenditures of approximately $15 million, $11 million and $12 million, respectively, were deferred and are being amortized, generally over 18 months to 3 years. Amortization of previously
deferred turnaround costs was $8 million in each of 2006 and 2005, and $12 million in 2004.

Additional information on
long-lived assets, deferred turnaround costs and related depreciation and amortization appears in Note 10 to the Consolidated Financial Statements.

GoodwillGoodwill represents the excess of purchase price paid over the fair value assigned to the net tangible and identifiable intangible assets of acquired businesses. Millennium evaluates the carrying
value of goodwill annually or more frequently if events or changes in circumstances indicate that the carrying amount may exceed fair value. Recoverability is determined by comparing the estimated fair value of the reporting unit to which the
goodwill applies to the carrying value, including goodwill, of that reporting unit. The carrying value of goodwill at December 31, 2006 was $104 million, of which $55 million was associated with Millenniums inorganics segment and $49
million with the acetyls business. The recoverability of Millenniums goodwill is dependent upon the future valuations associated with these businesses, which could change significantly based upon business performance or other factors.

Long-Term Employee Benefit CostsThe costs to Millennium of long-term employee benefits, particularly pension
and postretirement medical and life insurance benefits, are incurred over long periods of time, and involve many uncertainties over those periods. The net periodic benefit cost attributable to current periods is based on several assumptions about
such future uncertainties, and is sensitive to changes in those assumptions. It is managements responsibility, often with the assistance of independent experts, to select assumptions that in its judgment represent its best estimates of the
future effects of those uncertainties. It also is managements responsibility to review those assumptions periodically to reflect changes in economic or other factors that affect those assumptions.

The current benefit service costs, as well as the existing liabilities, for pensions and other postretirement benefits are measured on a
discounted present value basis. The discount rate is a current rate, related to the rate at which the liabilities could be settled. Millenniums assumed discount rate is based on average rates published by Moodys and Merrill Lynch for
high-quality (Aa rating) ten-year fixed income securities. For the purpose of measuring the U.S. benefit obligations at December 31, 2006, Millennium increased its assumed discount rate from 5.5% to 5.75%, reflecting market interest rates at
December 31, 2006. The 5.75% rate also will be used to measure net periodic benefit cost during 2007. A one percentage point reduction in the assumed discount rate would increase Millenniums benefit obligation for pensions and other
postretirement benefits by approximately $119 million, and would reduce Millenniums net income by approximately $9 million.

The benefit obligation and the periodic cost of postretirement medical benefits also are measured based on assumed rates of future increase in the per capita cost of covered health care benefits. As of
December 31, 2006, the assumed rate of increase was 9% for 2007, decreasing 1% per year to 6% in 2010 and 5% in 2012 and thereafter. A one percentage point change in the health care cost trend rate assumption would have no significant
effect on either the benefit liability or the net periodic cost.

##### Index to Financial Statements

The net periodic cost of pension benefits included in expense also is affected by the
expected long-term rate of return on plan assets assumption. Investment returns that are recognized currently in net income represent the expected long-term rate of return on plan assets applied to a market-related value of plan assets which, for
Millennium, is defined as the market value of assets. The expected rate of return on plan assets is a longer term rate, and is expected to change less frequently than the current assumed discount rate, reflecting long-term market expectations,
rather than current fluctuations in market conditions.

Millenniums expected long-term rate of return on U.S. plan
assets of 8% is based on the average level of earnings that its independent pension investment advisor had advised could be expected to be earned over time. The expectation is based on an asset allocation of 55% U.S. equity securities (9.5% expected
return), 15% non-U.S. equity securities (9.5% expected return), and 30% fixed income securities (5.5% expected return) recommended by the advisor, and has been adopted for the plans. The actual return on plan assets in 2006 was 11%.

The actual rate of return on plan assets may differ from the expected rate due to the volatility normally experienced in capital markets.
Managements goal is to manage the investments over the long term to achieve optimal returns with an acceptable level of risk and volatility. Based on the market value of plan assets at December 31, 2006, a one percentage point decrease in
this assumption for Millennium would decrease Millenniums net income by approximately $5 million.

Net periodic
pension cost recognized each year includes the expected asset earnings, rather than the actual earnings or loss. As a result of asset earnings significantly below the expected return on plan assets rate over the last several years, the level of
unrecognized investment losses, together with the net actuarial gains and losses, is $318 million at December 31, 2006. This unrecognized amount, to the extent it exceeds ten percent of the projected benefit obligation for the respective
plan, will be recognized as additional net periodic benefit cost over the average remaining service period of the participants in each plan. This annual amortization charge will be approximately $19 million per year based on the
December 31, 2006 unrecognized amount.

Additional information on the key assumptions underlying these benefit costs
appears in Note 16 to the Consolidated Financial Statements.

ACCOUNTING AND REPORTING CHANGES

Effective December 31, 2006, Millennium adopted the
provisions of Statement of Financial Accounting Standards (SFAS) No. 158, Employers Accounting for Defined Benefit Pension and Other Postretirement Plans- An Amendment of FASB Statements No. 87, 88, 106, and 132R,
which primarily requires an employer to recognize in its statement of financial position an asset for a plans overfunded status or a liability for a plans underfunded status through comprehensive income in the year in which changes
occur. Millenniums application of SFAS No. 158 as of December 31, 2006 resulted in increases of $4 million and $73 million in its current and long-term benefit liabilities, respectively, a decrease of $7 million in other assets,
a decrease of $27 million in deferred tax liabilities and an increase of $57 million in accumulated other comprehensive loss in its consolidated balance sheet as of December 31, 2006. (See Note 16 to the Consolidated Financial
Statements.)

In September 2006, the Financial Accounting Standards Board (FASB) issued SFAS No. 157,
Fair Value Measurements. The new standard defines fair value, establishes a framework for its measurement and expands disclosures about such measurements. For Millennium, the standard will be effective beginning in 2008. Millennium does not
expect the application of SFAS No. 157 to have a material effect on its consolidated financial statements.

In July
2006, the FASB issued Interpretation (FIN) No. 48, Accounting for Uncertainty in Income Taxes - An Interpretation of FASB Statement No. 109, to clarify the accounting for uncertain income tax positions.
FIN No. 48 prescribes, among other things, a recognition threshold and measurement attribute for the financial statement recognition and measurement of an uncertain tax position. The provisions of FIN No. 48 will apply to
Millennium beginning in 2007. Millennium expects the application of FIN No. 48 to result in an increase of $40 million to $50 million in its estimate of future obligations for income taxes and related interest.

Effective January 1, 2006, Millennium adopted the provisions of SFAS No. 123
(revised 2004), Share-Based Paymentusing the modified prospective method and, consequently, has not adjusted results of prior periods. Millennium previously accounted for these plans using the intrinsic value method prescribed in Accounting
Principles Board (APB) Opinion No. 25 and related interpretations.Millenniums application of SFAS No. 123 (revised 2004) had no material effect on its consolidated financial statements.

Effective April 1, 2006, Millennium adopted the provisions of Emerging Issues Task Force (EITF) Issue No. 04-13,
Accounting for Purchases and Sales of Inventory with the Same Counterparty. EITF Issue No. 04-13 requires that inventory purchases and sales transactions with the same counterparty that are entered into in contemplation of one another be
combined for purposes of applying APB Opinion No. 29, Accounting for Nonmonetary Transactions. The effect of this requirement is to reduce reported revenues and cost of sales for affected transactions. Millenniums application of
EITF 04-13 had no material effect on its consolidated financial statements.

In December 2003, the FASB issued
Interpretation No. 46 (Revised December 2003), Consolidation of Variable Interest Entities (FIN 46R), primarily to clarify the required accounting for interests in variable interest entities (VIEs). This standard
replaces FASB Interpretation No. 46, Consolidation of Variable Interest Entities, which was issued in January 2003 to address certain situations in which a company should include in its financial statements the assets, liabilities and
activities of another entity. Millennium evaluated its long-term obligations with one entity that may be a VIE. Millennium has no equity interest in this entity and has confirmed that the entity is consolidated by an equity owner. Millennium has not
been able to obtain the financial information from the entity necessary to determine whether Millennium is the primary beneficiary of the entity. Management of the entity cited confidentiality considerations with regard to the decision not to
provide certain financial information to Millennium. Millennium pays approximately $2 million in plant and equipment rental charges on an annual basis to this entity.

ENVIRONMENTAL MATTERS

Various environmental laws and regulations impose substantial
requirements upon the operations of Millennium. Millenniums policy is to be in compliance with such laws and regulations, which include, among others, the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA
or Superfund) as amended, the Resource Conservation and Recovery Act (RCRA) and the Clean Air Act Amendments (Clean Air Act). Millennium does not specifically track all recurring costs associated with managing
hazardous substances and pollution in ongoing operations. Such costs are included in cost of sales.

Millenniums
accrued liability for future environmental remediation costs at current and former plant sites and other remediation sites totaled $172 million as of December 31, 2006. The remediation expenditures are expected to occur over a number of
years, and not to be concentrated in any single year. In the opinion of management, there is no material estimable range of reasonably possible loss in excess of the liabilities recorded for environmental remediation. However, it is possible that
new information about the sites for which the accrual has been established, new technology or future developments such as involvement in investigations by regulatory agencies, could require Millennium to reassess its potential exposure related to
environmental matters. The liabilities for individual sites range from less than $1 million to $106 million. The $106 million liability relates to the Kalamazoo River Superfund Site. See Critical Accounting Policies above and the
Environmental Remediation section of Note 18 to the Consolidated Financial Statements for additional discussion of Millenniums liabilities for environmental remediation, including the liability related to the Kalamazoo River
Superfund Site.

Millennium also makes capital expenditures to
comply with environmental regulations. Capital expenditures for regulatory compliance totaled approximately $5 million in 2006 and $8 million in each of 2005 and 2004. Millennium currently estimates environmentally-related capital expenditures
at its facilities will be approximately $10 million in 2007 and $15 million in 2008, reflecting the addition of a new waste disposal landfill and fume containment equipment at a TiO2plant.

|Item 7A. | Quantitative and Qualitative Disclosures About Market Risk
|-------- | ----------------------------------------------------------

See Note  15 to the Consolidated Financial Statements for discussion of Millenniums management of commodity price risk,
foreign currency exposure and interest rate risk through its use of derivative instruments and hedging activities.

COMMODITY PRICE RISK

A substantial portion of Millenniums products and raw materials
are commodities whose prices fluctuate as market supply and demand fundamentals change. Accordingly, product margins and the level of Millenniums profitability tend to fluctuate with changes in the business cycle.

Millennium selectively entered into commodity derivative hedging transactions, primarily price swaps, options, and futures, to help
manage the exposure to commodity price risk with respect to purchases of raw materials and product sales. The net losses recognized in earnings in each of 2005 and 2004 were less than $1 million. During 2005 and 2004, the derivative transactions
were not significant compared to Millenniums overall inventory purchases and product sales; there were no derivative transactions in 2006. Millennium had no outstanding commodity derivative transactions at December 31, 2006 and 2005.

FOREIGN EXCHANGE RISK

Millennium manufactures and markets its products in a number of
countries throughout the world and, as a result, is exposed to changes in foreign currency exchange rates. Costs in some countries are incurred, in part, in currencies other than the applicable functional currency. Millenniums non-U.S.
operations account for approximately 58% of consolidated revenues and 53% of long-lived assets. Millennium has selectively utilized forward, swap and option derivative contracts with terms normally lasting less than three months to protect against
the adverse effect that exchange rate fluctuations may have on foreign currency denominated trade receivables and trade payables. These derivatives generally are not designated as hedges for accounting purposes. There were no outstanding foreign
currency forward, swap and option contracts at December 31, 2006 and 2005.

INTEREST RATE RISK

Millennium is exposed to interest rate risk with respect to variable rate
debt. At December 31, 2006, Millennium had $70 million of outstanding variable rate debt. Using sensitivity analysis and a hypothetical 10% increase in interest rates from those in effect at year end, the increase in annual interest
expense on the variable-rate debt would reduce net income by less than $1 million.

Derivative instruments have been
used selectively to manage the ratio of fixed- to variable-rate debt at Millennium. At December 31, 2006 and 2005, there were outstanding interest rate swap agreements in the notional amount of $175 million, which were designated as fair-value
hedges of underlying fixed-rate obligations. The fair value of these interest rate swap agreements was an obligation of $3 million and $4 million, respectively, at December 31, 2006 and 2005, resulting in a decrease in the carrying value
of long-term debt and the recognition of a corresponding liability. Using sensitivity analysis, the negative impact on the fair value of the obligation at December 31, 2006 would be approximately $1 million assuming a 10% unfavorable
change in variable interest rates.

MANAGEMENTS REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

The management of Millennium is
responsible for establishing and maintaining adequate internal control over financial reporting. Millenniums internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial
reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.

Millennium management assessed the effectiveness of Millenniums internal control over financial reporting as of December 31, 2006. In making this assessment, management used the criteria set forth by the Committee of Sponsoring
Organizations of the Treadway Commission in Internal ControlIntegrated Framework. Based on its assessment, Millenniums management has concluded that Millenniums internal control over financial reporting was effective as of
December 31, 2006 based on those criteria.

PricewaterhouseCoopers LLP, the independent registered public accounting firm that audited
the financial statements included in this Annual Report on Form 10-K, has audited managements assessment of the effectiveness of Millenniums internal control over financial reporting as of December 31, 2006, as stated in their
report that appears on the following page.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders

of Millennium Chemicals Inc.:

We have
completed integrated audits of Millennium Chemicals Inc.s 2006 and 2005 consolidated financial statements and of its internal control over financial reporting as of December 31, 2006, and an audit of its 2004 consolidated financial statements
in accordance with the standards of the Public Company Accounting Oversight Board (United States). Our opinions, based on our audits, are presented below.

Consolidated financial statements

In our opinion, the consolidated financial statements listed in
the accompanying index present fairly, in all material respects, the financial position of Millennium Chemicals Inc. and its subsidiariesat December 31, 2006 and 2005, and the results of their operations and their cash flows for each of the
three years in the period ended December 31, 2006in conformity with accounting principles generally accepted in the United States of America. These financial statements are the responsibility of the Company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 the standards of the Public Company Accounting Oversight Board (United States). 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 of financial statements 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.

As discussed in Note 2 to the consolidated financial statements, effective December 31, 2006, the Company changed its
method of accounting for defined benefit pension and other postretirement plans.

Internal control over financial reporting

Also, in our opinion, managements assessment, included in Managements Report on Internal Control Over FinancialReporting appearing under Item 8, that the Company maintained effective internal control over financial reporting as of December 31, 2006 based on criteria established in Internal Control - Integrated Framework issued by the Committee of
Sponsoring Organizations of the Treadway Commission (COSO), is fairly stated, in all material respects, based on those criteria. Furthermore, in our opinion, the Company maintained, in all material respects, effective internal control over financial
reporting as of December 31, 2006, based on criteria established in Internal Control - Integrated Framework issued by the COSO. The Companys management is responsible for maintaining effective internal control over financial reporting
and for its assessment of the effectiveness of internal control over financial reporting. Our responsibility is to express opinions on managements assessment and on the effectiveness of the Companys internal control over financial
reporting based on our audit. We conducted our audit of internal control over financial reporting in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the
audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. An audit of internal control over financial reporting includes obtaining an understanding of internal
control over financial reporting, evaluating managements assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such other procedures as we consider necessary in the circumstances. We
believe that our audit provides a reasonable basis for our opinions.

A companys internal control over financial reporting is a
process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A companys
internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail,

accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are
recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management
and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the companys assets that could have a material effect on the financial
statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also,
projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS(Continued)



|1. | Description of the Company and Operations
|-- | -----------------------------------------

Millennium Chemicals Inc., together with its consolidated subsidiaries (collectively, Millennium) is a global chemical company. On November 30, 2004, Lyondell Chemical Company (Lyondell)
acquired Millennium in a stock-for-stock business combination. As a result of the business combination, Millennium is a wholly-owned subsidiary of Lyondell. The consolidated financial statements of Millennium reflect its historical cost basis, and,
accordingly, do not reflect any purchase accounting adjustments related to the acquisition by Lyondell.

Millennium operates in two reportable segments: inorganic chemicals; and ethylene, co-products and derivatives (EC&D). Millenniums inorganic chemicals segment primarily produces titanium dioxide
(TiO2), but also produces titanium tetrachloride (TiCl4), titanyl sulfate (TiOSO4), ultra-fine TiO2and other inorganic chemicals. On February 23, 2007, Millennium signed an
agreement for a proposed sale of Millenniums worldwide inorganic chemicals business (see Note 22). Millenniums EC&D segment comprises its acetyls business and its equity investment in Equistar Chemicals, LP (together with its
consolidated subsidiaries, collectively, Equistar). The acetyls business produces vinyl acetate monomer (VAM), acetic acid and methanol. Millennium also produces fragrance and flavor chemicals, which is not a reportable
segment.

Millennium owns 29.5% of Equistar, which is a joint venture with Lyondell. Equistar manufactures and markets ethylene and its
co-products, primarily propylene, butadiene and aromatics. Equistar also manufactures and markets derivatives, primarily ethylene oxide, ethylene glycol and polyethylene, and fuel products such as methyl tertiary butyl alcohol (MTBE) and
alkylate. Millennium accounts for its interest in Equistar using the equity method.



|2. | Summary of Significant Accounting Policies
|-- | ------------------------------------------

Basis of PresentationThe consolidated financial statements include the accounts of Millennium Chemicals Inc. and its consolidated subsidiaries. Investments in joint ventures where Millennium exerts a
certain level of management control, but lacks full decision making ability over all major issues, are accounted for using the equity method.

Revenue RecognitionRevenue from product sales is recognized at the time of transfer of title and risk of loss to the customer, which usually occurs at the time of shipment. Revenue is recognized at the time of delivery if
Millennium retains the risk of loss during shipment. For products that are shipped on a consignment basis, revenue is recognized when the customer uses the product. Costs incurred in shipping products sold are included in cost of sales. Billings to
customers for shipping costs are included in sales revenue.

Cash and Cash EquivalentsCash equivalents consist of highly
liquid debt instruments such as certificates of deposit, commercial paper and money market accounts. Cash equivalents include instruments with maturities of three months or less when acquired. Cash equivalents are stated at cost, which approximates
fair value. Millenniums policy is to invest cash in conservative, highly rated instruments and to limit the amount of credit exposure to any one institution.

Millennium has no requirements for compensating balances in a specific amount at a specific point in time. Millennium does maintain compensating balances for some of its banking services and products. Such balances
are maintained on an average basis and are solely at Millenniums discretion.

Allowance for Doubtful AccountsMillennium
establishes provisions for doubtful accounts receivable based on managements estimates of amounts that it believes are unlikely to be collected. Collectability of receivables is reviewed and the allowance for doubtful accounts is adjusted at
least quarterly, based on aging of specific accounts and other available information about the associated customers.

|2. | Summary of Significant Accounting Policies  (Continued)
|-- | --------------------------------------------------------

InventoriesInventories are stated at the lower of cost or market. Cost is determined using the first-in, first-out method for substantially all inventories, except for materials and
supplies, which are valued using the average cost method.

Property, Plant and EquipmentProperty, plant and equipment are
recorded at cost. Depreciation is computed using the straight-line method over the estimated useful asset lives, generally 20 to 40 years for buildings and 5 to 25 years for machinery and equipment. Upon retirement or sale, Millennium removes the
cost of the asset and the related accumulated depreciation from the accounts and reflects any resulting gain or loss in the consolidated statement of income. Millenniums policy is to capitalize interest cost incurred on debt during the
construction of major projects exceeding one year.

Long-Lived Asset ImpairmentMillennium evaluates long-lived assets,
including identifiable intangible assets, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. When it is probable that undiscounted future cash flows will not be sufficient
to recover an assets carrying amount, the asset is written down to its estimated fair value.

GoodwillGoodwill
represents the excess of purchase price paid over the fair value assigned to the net tangible and identifiable intangible assets of acquired businesses. Goodwill is reviewed for impairment at least annually.

Identifiable Intangible AssetsCosts to purchase and to develop software for internal use are deferred and amortized on a straight-line basis
over periods of 3 to 7 years.

Costs of major maintenance and repairs incurred as part of substantial overhauls or turnarounds of major
units at Millenniums manufacturing facilities are deferred and amortized using the straight-line method over the period until the next planned turnaround, predominantly 18 months to 3 years. These costs are necessary to maintain, extend and
improve the operating capacity and efficiency rates of the production units.

Other intangible assets are carried at cost or amortized cost
and primarily consist of deferred debt issuance costs, patents and license costs. These assets are amortized using the straight-line method over their estimated useful lives or over the term of the related agreement, if shorter.

Environmental Remediation CostsAnticipated expenditures related to investigation and remediation of contaminated sites, which include
current and former plant sites and other remediation sites, are accrued when it is probable a liability has been incurred and the amount of the liability can reasonably be estimated. Only ongoing operating and monitoring costs, the timing of which
can be determined with reasonable certainty, are discounted to present value. Future legal costs associated with such matters, which generally are not estimable, are not included in these liabilities.

Legal CostsMillennium expenses legal costs, including those incurred in connection with loss contingencies, as incurred.

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, as well as the net tax effects of net operating loss carryforwards. Valuation allowances are provided against deferred tax assets when it is more likely than
not that some portion or all of the deferred tax asset will not be realized.

|2. | Summary of Significant Accounting Policies  (Continued)
|-- | --------------------------------------------------------

Minority InterestMinority interest represents the interests of unaffiliated investors
in a partnership that owns the LaPorte Methanol Company plant in LaPorte, Texas, and in Millenniums TiO2operations in Brazil.

Foreign Currency TranslationMillennium operates primarily in three functional currencies: the euro for
operations in Europe, the real for operations in Brazil, and the U.S. dollar for the U. S. and other locations, including manufacturing and marketing operations in Australia, product sales of which are generally in U.S. dollars.

Derivative InstrumentsGains and losses on derivative instruments are classified in the same category as the item being hedged.

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 periods. Actual results could differ from those estimates.

ReclassificationsCertain previously reported amounts
have been reclassified to conform to classifications adopted in 2006.

Accounting and Reporting ChangesEffective
December 31, 2006, Millennium adopted the provisions of Statement of Financial Accounting Standards (SFAS) No. 158, Employers Accounting for Defined Benefit Pension and Other Postretirement Plans- An Amendment of FASB
Statements No. 87, 88, 106, and 132R, which primarily requires an employer to recognize in its statement of financial position an asset for a plans overfunded status or a liability for a plans underfunded status through
comprehensive income in the year in which changes occur. Millenniums application of SFAS No. 158 as of December 31, 2006 resulted in increases of $4 million and $73 million in its current and long-term benefit liabilities,
respectively, a decrease of $7 million in other assets, a decrease of $27 million in deferred tax liabilities and an increase of $57 million in accumulated other comprehensive loss in its consolidated balance sheet as of
December 31, 2006. (See Note 16.)

In September 2006, the Financial Accounting Standards Board (FASB) issued SFAS
No. 157, Fair Value Measurements. The new standard defines fair value, establishes a framework for its measurement and expands disclosures about such measurements. For Millennium, the standard will be effective beginning in 2008.
Millennium does not expect the application of SFAS No. 157 to have a material effect on its consolidated financial statements.

In
July 2006, the FASB issued Interpretation (FIN) No. 48, Accounting for Uncertainty in Income TaxesAn Interpretation of FASB Statement No. 109, to clarify the accounting for uncertain income tax positions.
FIN No. 48 prescribes, among other things, a recognition threshold and measurement attribute for the financial statement recognition and measurement of an uncertain tax position. The provisions of FIN No. 48 will apply to
Millennium beginning in 2007. Millennium expects the application of FIN No. 48 to result in an increase of $40 million to $50 million in its estimate of future obligations for income taxes and related interest.

Effective January 1, 2006, Millennium adopted the provisions of SFAS No. 123 (revised 2004), Share-Based Paymentusing the modified
prospective method and, consequently, has not adjusted results of prior periods. Millennium previously accounted for these plans using the intrinsic value method prescribed in Accounting Principles Board (APB) Opinion No. 25 and
related interpretations.Millenniums application of SFAS No. 123 (revised 2004) had no material effect on its consolidated financial statements.

|2. | Summary of Significant Accounting Policies  (Continued)
|-- | --------------------------------------------------------

Effective April 1, 2006, Millennium adopted the provisions of Emerging Issues Task Force (EITF) Issue No. 04-13, Accounting for Purchases and Sales of Inventory with the
Same Counterparty. EITF Issue No. 04-13 requires that inventory purchases and sales transactions with the same counterparty that are entered into in contemplation of one another be combined for purposes of applying APB Opinion No. 29,
Accounting for Nonmonetary Transactions. The effect of this requirement is to reduce reported revenues and cost of sales for affected transactions. Millenniums application of EITF 04-13 had no material effect on its consolidated
financial statements.

In December 2003, the FASB issued Interpretation No. 46 (Revised December 2003), Consolidation of Variable
Interest Entities (FIN 46R), primarily to clarify the required accounting for interests in variable interest entities (VIEs). This standard replaces FASB Interpretation No. 46, Consolidation of Variable Interest
Entities, which was issued in January 2003 to address certain situations in which a company should include in its financial statements the assets, liabilities and activities of another entity. Millennium evaluated its long-term obligations with
one entity that may be a VIE. Millennium has no equity interest in this entity and has confirmed that the entity is consolidated by an equity owner. Millennium has not been able to obtain the financial information from the entity necessary to
determine whether Millennium is the primary beneficiary of the entity. Management of the entity cited confidentiality considerations with regard to the decision not to provide certain financial information to Millennium. Millennium pays
approximately $2 million in plant and equipment rental charges on an annual basis to this entity.



|3. | Hurricane Effects
|-- | -----------------

During
2005, two major hurricanes impacted the chemical and related industries in the coastal and off-shore regions of the Gulf of Mexico. Net income in 2005, including Millenniums equity interest in Equistar, reflected charges totaling
$14 million, before tax, representing Millenniums exposure to industry losses expected to be underwritten by industry insurance consortia, primarily resulting from hurricane damages.

As a result of Hurricane Rita, Millennium and Equistar also incurred various costs that are subject to insurance reimbursements. Such costs include those
incurred in conjunction with suspending operations at substantially all of Millenniums and Equistars Gulf Coast plants, minor damage to facilities, and costs to restore operations. Net income in 2005 included $6 million of such
costs, including Millenniums share of Equistars costs of $19 million, of which all but a $5 million deductible under the relevant insurance policies are subject to reimbursement through insurance. Millennium recognized benefits
from insurance reimbursements of less than $1 million in 2006 and none in 2005.



|4. | Acquisition by Lyondell Chemical Company
|-- | ----------------------------------------

On November 30, 2004, Millennium was acquired by Lyondell in a stock-for-stock business combination. As a result of the acquisition, each share of Millenniums common stock outstanding immediately prior to
the acquisition was converted into the right to receive 0.95 shares of Lyondell common stock, and Millennium became a wholly-owned subsidiary of Lyondell. Millennium incurred approximately $71 million of costs in connection with the
acquisition. The consolidated financial statements of Millennium reflect its historical cost basis, and, accordingly, do not reflect any purchase accounting adjustments related to the acquisition by Lyondell. As a result of the acquisition, Lyondell
and Millennium entered into an agreement for the provision of administrative services, at cost, by Lyondell and a tax-sharing agreement. See Notes 6 and 17 for Millenniums transactions with Lyondell and Equistar.

|5. | Asset Impairments
|-- | -----------------

In 2003, Millennium recognized the impairment of the entire book value of property, plant and equipment at Millenniums Le Havre, France TiO2manufacturing plant. Capital expenditures at this plant of $15 million during each of 2006 and 2005 and $14 million during 2004 were reflected in
asset impairments. At December 31, 2006 and 2005, the carrying value of the property, plant and equipment at the Le Havre manufacturing plant was zero. Also in 2006, Millennium recognized an $7 million charge for impairment of certain software
costs.



|6. | Related Party Transactions
|-- | --------------------------

Millennium conducts transactions with Lyondell, Equistar and Occidental Petroleum Corporation (together with its subsidiaries and affiliates, collectively Occidental), all of which are considered related parties. Millennium is a
wholly-owned subsidiary of Lyondell as a result of the acquisition of Millennium by Lyondell on November 30, 2004. Occidental is a related party of Lyondell. Millennium owns 29.5% of Equistar (see Note 7).

Product Transactions with EquistarMillennium purchases ethylene from Equistar 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 from Equistar. The initial term of the contract expired December 31, 2000
and it continues thereafter for one-year periods unless either party serves notice of termination twelve months in advance.

Also,
Millennium sells VAM to Equistar under an agreement that requires Equistar to purchase 100% of its VAM raw material requirements at market-related prices from Millennium for the production of ethylene vinyl acetate products at its LaPorte, Texas;
Clinton, Iowa and Morris, Illinois plants, and 100% of its glacial acetic acid requirements at market-related prices from Millennium for the production of glycol ether acetate at its Bayport, Texas plant. The initial term of these agreements expired
December 31, 2005 and continues year-to-year thereafter unless terminated by either party.

Product Transactions with
LyondellMillennium sells VAM and glacial acetic acid to Lyondell at market-related prices under various agreements. The initial one-year term of these agreements expired in 2006 and continues year-to-year thereafter, unless terminated by
either party. Prior to November 30, 2004, such transactions were not related party transactions.

Product Transactions with
OccidentalMillennium purchases 100% of its domestic sodium silicate requirements and a portion of its domestic chlorine requirements at market-related prices pursuant to agreements with Occidental. The initial terms of the sodium silicate
and chlorine agreements expire December 31, 2009.

Shared Services and Shared-Site Agreements with LyondellUnder a shared
services agreement, Lyondell provides office space and various services to Millennium including information technology, sales and marketing, supply chain, and other administrative and support services (see Note 17). Lyondell charges Millennium for
Millenniums share of the cost of such services. Direct costs, incurred exclusively for Millennium, also are charged to Millennium.

Equistars 2006 earnings reflect a charge of $135 million for impairment of the net book
value of its idled Lake Charles, Louisiana ethylene facility. In the third quarter of 2006, Equistar undertook a study of the feasibility, cost and time required to restart the Lake Charles ethylene facility. As a result, management determined that
restarting the facility would not be justified. The remaining net book value of the related assets of $10 million represents an estimate, based on probabilities, of alternative-use value. Equistar does not expect to incur any significant future
costs with respect to the facility.



|8. | Accounts Receivable
|-- | -------------------

Millennium sells its products primarily to other industrial concerns in the petrochemicals and coatings industries. Millennium performs ongoing credit evaluations of its customers financial condition and, in certain circumstances,
requires letters of credit from them. Millenniums allowance for doubtful accounts receivable, which is reflected in the Consolidated Balance Sheets as a reduction of accounts receivable, totaled $5 million and $4 million at
December 31, 2006 and 2005, respectively. The Consolidated Statements of Income for 2006, 2005 and 2004 included provisions for doubtful accounts of $1 million, $5 million and $1 million, respectively.

Aggregate maturities of all long-term debt during the next five years are $4 million in 2007,
$376 million in 2008, $3 million in 2009, $73 million in 2010, $3 million in 2011 and $394 million thereafter.

Millennium may currently redeem its 9.25% Senior Notes due 2008 upon payment of the present value of future interest and principal amounts, using a specified discount rate. Additionally, Millennium may redeem the Australian senior secured
term loan due 2010 at 100% of the principal amount.

During 2006, Millennium obtained an amendment to its $150 million senior secured
revolving credit facility and to the indenture governing the 4% Convertible Senior Debentures primarily to exclude a subsidiary of Millennium, Millennium Holdings, LLC and its subsidiaries (collectively Millennium Holdings), from
events-of-default provisions that could be triggered in connection with judgments against Millennium Holdings. See Litigation section of Note 18.

Also during 2006, a U.K. subsidiary of Millennium entered into a new 60 million, five-year, revolving credit facility, which, subject to permitted liens, is generally secured by the subsidiarys
inventory, accounts receivable and certain other assets. Availability under the U.K. facility, which was 46 million, or approximately $61 million, at December 31, 2006, gave effect to the borrowing base as determined using a
formula applied to accounts receivable and inventory balances and was reduced to the extent of outstanding borrowing and letters of credit provided under the facility. At December 31, 2006, there was no outstanding borrowing and there were no
letters of credit under the facility. The U.K. facility bears interest at LIBOR plus 1.25%.

During 2006, Millennium purchased $158 million
principal amount of its 7% Senior Notes due 2006, paying a premium of $2 million, and purchased $85 million principal amount of the 9.25% Senior Notes due 2008, paying a premium of $5 million. Other reductions of debt in 2006 totaled
$39 million, including $29 million principal amount of the Australian term loan.

|13. | Long-Term Debt  (Continued)
|--- | ----------------------------

During 2005, Millennium purchased $342 million principal amount of its 7% Senior Notes due 2006; $13 million of the 9.25% Senior Notes due 2008 and $1 million of the 7.625% Senior Debentures due 2026, paying total premiums of
$10 million.

Millennium amended and restated its $150 million senior secured credit facility in 2005, replacing it with a
$125 million U.S. senior secured revolving credit facility, a $25 million Australian senior secured revolving credit facility, and a $100 million Australian senior secured term loan, all of which mature in August 2010. Availability
under the revolving credit facilities is reduced to the extent of outstanding letters of credit provided under the facilities. There were $22 million of outstanding letters of credit under the U.S. revolving credit facility and none outstanding
under the Australian revolving credit facility as of December 31, 2006. There was no outstanding borrowing under either revolving credit facility as of December 31, 2006. The U.S. revolving credit facility and the Australian term loan
generally bear interest between LIBOR plus 1% and LIBOR plus 2%, as the case may be, based upon the Leverage Ratio (as defined) as of the most recent determination date. The Australian revolving credit facility generally bears interest based on the
Australian Bank Bill Rate (as defined) plus between 1% and 2%, as the case may be, based upon the Leverage Ratio as of the most recent determination date.

Also in 2005, Millennium obtained an amendment to its previous $150 million senior secured credit facility to allow for the unrestricted repurchase of indebtedness in the form of bonds, debentures, notes or
similar instruments. On February 2, 2005, as a result of certain adjustments and charges related to the February 2005 restatement of Millenniums financial statements, Millennium entered into an amendment and waiver to its previous
$150 million credit facility, which amended the credit facility definition of EBITDA and waived any and all defaults or events of default that may have occurred on or prior to the amendment and waiver.

Pursuant to the indenture governing the 9.25% Senior Notes, Millennium was required to purchase $4 million principal amount of its 9.25% Senior
Notes and pay a 1% premium as a result of Lyondells acquisition of Millennium on November 30, 2004.

The obligations under the
U.S. revolving credit facility, subject to permitted liens, are generally secured by Millenniums equity interests in certain U.S. and non-U.S. subsidiaries, cash distributions made by Equistar, certain assets of Millennium and certain of its
U.S. subsidiaries and guarantees by Millennium and certain U.S. subsidiaries.

The obligations under the Australian term loan and revolving
credit facility, subject to permitted liens, are secured by Millenniums equity interests in certain non-U.S. subsidiaries, substantially all of the assets of those subsidiaries, including cash and proceeds therefrom, and guarantees by
Millennium and certain of its subsidiaries.

In addition to letters of credit outstanding under the U.S. revolving credit facility,
Millennium had other outstanding letters of credit and bank guarantees under other arrangements of $8 million at December 31, 2006.

|13. | Long-Term Debt  (Continued)
|--- | ----------------------------

Millenniums facilities and its indentures contain covenants that, subject to exceptions, restrict, among other things, dividends, debt incurrence, lien incurrence, investments, sale and leaseback transactions, sales of assets,
affiliate transactions, mergers, accounts receivable securitization transactions, purchase of equity and payments on indebtedness. Pursuant to these provisions, Millennium is prohibited from making restricted payments, including paying certain
dividends. Other than the U.K. facility, Millenniums facilities also contain covenants that require the maintenance of specified financial ratios: (1) the Leverage Ratio (as defined) is required to be less than 4.50 to 1 and (2) the
Interest Coverage Ratio (as defined) for any period of four consecutive fiscal quarters is required to be equal to or greater than 2.25 to 1. Millenniums U.K. facility does not require the maintenance of specified financial ratios as long as
certain conditions are met.

Millennium has outstanding $150 million aggregate principal amount of 4% Convertible Senior Debentures,
which are due in 2023, unless earlier redeemed, converted or repurchased. As a result of Lyondells acquisition of Millennium, Millennium and Lyondell executed a supplemental indenture providing that the holders of the 4% Convertible Senior
Debentures may convert their debentures into shares of Lyondells common stock (or, at Lyondells discretion, equivalent cash or a combination thereof). As of December 31, 2006, based on a quarterly test related to the price of
Lyondell common stock, the Debentures were convertible at a conversion price of $13.38 per share, which is equivalent to a conversion rate of 74.758 Lyondell shares per one thousand dollar principal amount of the Debentures. As of December 31,
2006, the amount of Debentures converted into shares of Lyondell common stock was not significant.

The Debentures are redeemable at
Millenniums option beginning November 15, 2010 at a redemption price equal to 100% of their principal amount. On November 15 in each of 2010, 2013 and 2018, holders of the Debentures will have the right to require Millennium to
repurchase all or some of the Debentures they own at a purchase price equal to 100% of their principal amount. Millennium may choose to pay the purchase price in cash or shares of Lyondells common stock or any combination thereof. In the event
of a conversion request as a result of the long-term credit rating assigned to the Debentures being either Caa1 or lower, in the case of Moodys Investors Service (Moodys), or B- or lower in the case of Standard &
Poors (S&P) rating service, or if both rating agencies discontinue, withdraw or suspend their ratings, Millennium can deliver cash, or a combination of cash and shares of Lyondell common stock, in lieu of shares of Lyondell
common stock. The Debentures are currently rated B1 by Moodys and B+ by S&P. Holders of the Debentures also have the right to require Millennium to repurchase all or some of the Debentures at a cash purchase price equal to 100% of their
principal amount, upon the occurrence of certain events constituting a Fundamental Change, as defined in the indenture. Lyondells acquisition of Millennium was not considered a Fundamental Change.

Millenniums revolving credit facility is guaranteed by Millennium and Millennium America Inc. (Millennium America), a subsidiary of
Millennium; Millenniums 7% Senior Notes, 7.625% Senior Debentures and 9.25% Senior Notes were issued by Millennium America and are fully and unconditionally guaranteed by Millennium; and Millenniums 4% Convertible Senior Debentures were
issued by Millennium and are guaranteed fully and unconditionally by Millennium America.

|14. | Lease Commitments
|--- | -----------------

Millennium leases various facilities and equipment under noncancelable operating lease arrangements for varying periods. As of December 31, 2006, future minimum lease payments for the next five years and thereafter, relating to all
noncancelable operating leases with terms in excess of one year were as follows:

Net rental expense was $26 million in 2006 and $24 million in each of 2005 and 2004.



|15. | Financial Instruments and Derivatives
|--- | -------------------------------------

Millennium is exposed to market risk, such as changes in commodity pricing, currency exchange rates and interest rates. To manage the volatility related to these exposures, Millennium selectively enters into
derivative transactions pursuant to Millenniums policies. Designation of the derivatives as fair-value or cash-flow hedges is performed on a specific exposure basis. Hedge accounting may not be elected with respect to certain short-term
exposures. The changes in fair value of these hedging instruments are offset in part or in whole by corresponding changes in the fair value or cash flows of the underlying exposures being hedged. Millennium does not hold or issue derivative
financial instruments for speculative or trading purposes.

Foreign Currency Exposure ManagementMillennium manufactures and
markets its products in a number of countries throughout the world and, as a result, is exposed to changes in currency exchange rates. Costs in some countries are incurred, in part, in currencies other than the applicable functional currency.
Millennium selectively utilizes forward, swap and option derivative contracts with terms normally lasting less than three months to protect against the adverse effect that exchange rate fluctuations may have on foreign currency denominated trade
receivables and trade payables. These derivatives generally are not designated as hedges for accounting purposes. The gains and losses on both the derivatives and the foreign currency denominated trade receivables and payables are recorded in
earnings. Net gains and losses on forward exchange contracts included in earnings, which offset similar amounts from foreign currency denominated trade receivables and payables, were a net gain of $1 million in 2006 and net losses of less than
$1 million in each of 2005 and 2004. At December 31, 2006, Millennium had no outstanding foreign currency forward, swap or option contracts.

In addition, Millennium selectively utilizes currency forward and swap contracts that qualify as cash-flow hedges. These are intended to offset the effect of exchange rate fluctuations on forecasted or committed sales
and purchases. Gains and losses on these instruments are deferred in accumulated other comprehensive income (AOCI) until the underlying transaction is recognized in earnings. The gains or losses are reported in sales and other operating
revenues or cost of sales to match the underlying transaction being hedged. Net gains related to forward exchange contracts designated as cash-flow hedges of $1 million in 2006 and net losses of $1 million in each of 2005 and 2004 were
reclassified to earnings to match the losses on the underlying transaction being hedged. There were no amounts related to foreign exchange cash-flow hedges deferred in AOCI at December 31, 2006 and 2005.

|15. | Financial Instruments and Derivatives  (Continued)
|--- | ---------------------------------------------------

As a result of foreign currency transactions, Millennium had a net gain of $2 million in 2006, a net loss of $1 million in 2005 and a net gain of $5 million in 2004, net of gains or losses on related
hedge transactions, which were not significant.

Interest Rate Risk ManagementMillennium selectively uses derivative
instruments to manage the ratio of fixed to variable-rate debt. At December 31, 2006, Millennium had outstanding interest rate swap agreements in the notional amount of $175 million, which were designated as fair-value hedges of underlying
fixed-rate obligations. At December 31, 2006 and 2005, the fair value of these interest rate swap agreements was an obligation of $3 million and $4 million, respectively, resulting in a decrease in the carrying value of long-term debt
and the recognition of a corresponding liability in each period. The net gains and losses resulting from adjustment of both the interest rate swaps and the hedged portion of the underlying debt to fair value are recorded in interest expense. In
September 2004, Millennium terminated all of the interest rate swap agreements that were in effect at that time and received proceeds of approximately $3 million. The carrying value of long-term debt was increased in September 2004, by a gain
of approximately $2 million that was deferred. This deferred gain will be recognized as a reduction of interest expense ratably over the remaining term of the underlying fixed-rate obligation previously hedged.

Commodity Price Risk ManagementMillennium is exposed to commodity price volatility related to anticipated purchases of natural gas and raw
materials, and to product sales. Millennium selectively uses commodity swap, options, and futures contracts with various terms to manage the volatility related to these risks. Cash-flow hedge accounting is normally elected for these derivative
transactions; however, in some cases, when the duration of a derivative is short, hedge accounting is not elected. When hedge accounting is not elected, the changes in fair value of these instruments are recorded in earnings. When hedge accounting
is elected, gains and losses on these instruments are deferred in AOCI until the underlying transaction is recognized in earnings. There were no derivative transactions in 2006. Net losses included in earnings were less than $1 million in each
of the years 2005 and 2004. As of December 31, 2006 and 2005, there were no commodity derivative instruments outstanding and no amounts deferred in AOCI.

The carrying value and the estimated fair value of Millenniums non-current, non-derivative financial instruments as of December 31, 2006 and 2005 are shown in the table below:



|                                             |  |               |     |           |   |               |  |           |       |  |   |

|Millions of dollars                          |  | CarryingValue |     | FairValue |   | CarryingValue |  | FairValue
|Investments and long-term receivables        |  | $             | 473 |           | $ | 1,333         |  | $         | 467   |  | $ | 1,322
|Long-term debt, including current maturities |  |               | 853 |           |   | 991           |  |           | 1,135 |  |   | 1,291

Long-term debt, including amounts due within one year, was valued based upon the borrowing rates
currently available to Millennium for debt with terms and average maturities similar to Millenniums debt portfolio except that, for the 4% Convertible Senior Debentures, quoted market values were used. The investment in Equistar Chemicals, LP,
was valued using current financial and other available information. The fair value of all non-derivative financial instruments included in current assets and current liabilities, including cash and cash equivalents, other short-term investments,
accounts receivable, accounts payable and notes payable, approximated their carrying value due to their short maturity.

|15. | Financial Instruments and Derivatives  (Continued)
|--- | ---------------------------------------------------

Financial instruments that potentially subject Millennium to significant concentrations of credit risk consist principally of temporary cash investments, foreign currency and interest rate derivative contracts and
accounts receivable. Millennium maintains its investments and enters contracts with major institutions that it deems credit worthy, generally financial institutions that provide Millennium with debt financing.

Millennium sells a broad range of commodity, industrial, performance and specialty chemicals to a diverse group of customers operating throughout the
world. Accordingly, there is no significant concentration of risk in any one particular country. A substantial portion of the sales revenues for the inorganic chemicals segment in 2006, 2005 and 2004 was from customers in the global paint and
coatings industries, which have experienced relatively stable demand. Credit limits, ongoing credit evaluation, and account-monitoring procedures are utilized to minimize credit risk. Collateral is generally not required, but may be used under
certain circumstances or in certain markets, particularly in lesser-developed countries of the world. Credit losses to customers operating in this industry have not been material.



|16. | Pension and Other Postretirement Benefits
|--- | -----------------------------------------

Millennium has defined benefit pension plans, which cover employees in the United States and a number of other countries. Retirement benefits are generally based on years of credited service and average compensation
as defined under the respective plan provisions. Millennium funds the plans through contributions to pension trust funds, generally subject to minimum funding requirements as provided by applicable law. In addition, Millennium sponsors
postretirement benefit plans other than pensions, which provide medical and life insurance to most employees and their dependents.

The net effect of curtailments, settlements and special termination benefits in 2004 reflects the
vesting of pension benefits of officers and certain key employees as a result of Lyondells November 30, 2004 acquisition of Millennium.

Estimated amortization of the actuarial loss and prior service cost components of Accumulated Other Comprehensive Income (AOCI) for the U.S. and non-U.S. defined benefit pension plans to be included in net periodic pension cost
in 2007 is $19 million and $1 million, respectively.

The assumptions used in determining net periodic pension cost were as follows for the year ended
December 31:



|                                           |  |      |   |  |          |   |  |      |   |  |          |   |  |      |   |  |          |

|Discount rate                              |  | 5.50 | % |  | 5.03     | % |  | 5.75 | % |  | 5.41     | % |  | 6.00 | % |  | 5.66     | %

The discount rates used in determining net postretirement benefit cost were 5.5% for 2006, 5.75%
for 2005 and 6.0% for 2004.

The assumed annual rate of increase in the per capita cost of covered health care benefits as of
December 31, 2006 was 9% for 2007, decreasing 1% per year to 6% in 2010 and 5% for 2012 and thereafter. At December 31, 2005, similar cost escalation assumptions were used. A 1% increase or decrease in the assumed health care cost
trend rates in each year would change the accumulated other postretirement benefit liability as of December 31, 2006 by less than $1 million and would not have a material effect on the aggregate service and interest components of the net
periodic other postretirement benefit cost for the year then ended.

Managements goal is to manage pension investments over the long
term to achieve optimal returns with an acceptable level of risk and volatility. Investment policies limit the concentration of investments in one industry to 20% and in one company to 5%. Total plan assets at December 31, 2006 and 2005 did not
include any Lyondell common stock. The investments are marketable securities that provide sufficient liquidity to meet expected benefit obligation payments.

As part of the Lyondell consolidated group, management reviewed its asset allocation and expected long-term rate of return assumptions, and obtained an updated asset allocation study from the independent pension
investment advisor, including updated expectations for long-term market earnings rates for various classes of investments. Based on this review, management reduced its expected long-term rate of return on plan assets to 8% beginning December 1,
2004.

Millennium expects to contribute approximately $35 million to its pension plans in 2007.

As of December 31, 2006, future expected benefit payments by the plans, which reflect expected future service, as appropriate, were
as follows:

Millennium also maintains defined contribution savings plans for eligible employees. Contributions
to these plans by Millennium were $3 million in each of 2006 and 2005 and $4 million in 2004.

In April 2004, Millennium reduced
the level of retiree medical benefits provided to essentially all of its retirees by offering a monthly subsidy to retirees that enroll in designated preferred provider organization plans or Medicare supplement insurance plans. This reduction in
benefits is expected to reduce Millenniums accumulated postretirement benefit obligation by approximately $47 million. Beginning in 2004, this reduction is being recognized ratably over approximately thirteen years through net periodic
benefit cost for other postretirement benefits.

|17. | Income Taxes
|--- | ------------

Under a
tax-sharing agreement between Millennium and Lyondell, Millenniums U.S. federal income tax is substantially the same as it would have been had Millennium not been included in Lyondells consolidated U.S. income tax return, but filed a
separate return. Any resulting receivable or payable is settled with Lyondell. The agreement provides for the calculation of the current U.S. tax considering all statutory limitations on the utilization of carryforward benefits resulting from the
acquisition transaction itself. In addition, any current cash benefit resulting from utilization of certain carryforward attributes with respect to which benefits have not been recognized for financial reporting purposes is not remitted to
Millennium until the related issues have been resolved with the appropriate taxing authority. The same principles apply to tax sharing for unitary, consolidated and combined state income taxes.

The significant components of the provision for income taxes were as follows for the years ended December 31:

At December 31, 2006, Millennium had U.S. federal, state and non-U.S. tax loss carryforwards,
the tax benefit of which would be $118 million at current statutory rates. The federal loss carryforward benefits of $32 million will begin expiring in 2022, and the other tax loss carryforward benefits generally have no expiration date.
However, tax loss carryforward benefits generated in the United Kingdom (the U.K.) are subject to certain limitations. Federal AMT credits of $41 million have no expiration date.

|--- | --------------------------

Deferred tax asset valuation allowances included $121 million and $94 million for the net deferred tax assets of Millenniums French subsidiaries at December 31, 2006 and 2005, respectively. Provisions of $23 million and
$12 million in 2006 and 2005, respectively, increased the allowance for the French net operating loss carryforwards and other deferred tax assets. The settlement of a French tax audit resulted in a $7 million decrease in a deferred tax asset
related to net operating loss carryforwards with a corresponding decrease in the valuation allowance. Valuation allowances totaling $5 million were included at December 31, 2005 due to the uncertainty of the realization of deferred tax
assets for certain state net operating loss carryforwards. The state tax loss carryforwards were no longer considered realizable as of December 31, 2006 and the associated deferred tax asset was written off against the valuation allowance.
Other changes in the valuation allowance included the effects of foreign currency translation. The deferred tax asset valuation allowance at December 31, 2004 was $98 million.

Certain income tax returns for Millenniums U.S. and non-U.S. subsidiaries are currently under examination by the Internal Revenue Service (IRS) and various other non-U.S. and
state tax authorities. In many cases, these audits result in proposed assessments by the tax authority. Millennium believes that its tax positions comply with applicable tax law and intends to defend its positions through appropriate administrative
and judicial processes. Millennium believes it has adequately provided for any probable outcomes related to these matters.

Millennium has
entered into tax-sharing and indemnification agreements with Hanson plc (Hanson) in which Millennium and Hanson generally agreed to indemnify each other for certain income tax liabilities attributable to periods prior to the demerger.

The American Jobs Creation Act of 2004 (the Act) provides a tax deduction for qualified production activities. During 2005,
Millennium utilized its federal tax loss carryforwards and, as a result did not benefit from these provisions. Due to the full utilization of all available federal tax loss carryforwards during 2006, Millennium recognized a benefit of $3 million
during 2006 related to qualified production activities for a portion of 2006.

The Act also provided tax benefits with respect to the
repatriation of foreign earnings that can result in a significant reduction in the effective tax rate on certain non-U.S. earnings repatriated during a one year period. Millennium elected to repatriate, during 2005, certain non-U.S. earnings that
had previously been identified as likely to be repatriated as well as additional earnings previously expected to be indefinitely invested.

During 2005, $297 million, including non-U.S. Millennium earnings and returns of investment, was repatriated. The associated tax provisions were $3 million in 2005 and a net benefit of approximately $1 million in 2004, after
taking into effect a $19 million deferred tax provision recorded in 2003.

Millennium has determined that the undistributed earnings
of foreign subsidiaries will be permanently reinvested. The undistributed earnings of foreign subsidiaries aggregated $39 million at December 31, 2006. It is not practicable to calculate the unrecognized deferred tax liability on those
earnings.

Millennium recorded a tax benefit of $80 million in 2006 and tax expense of $13 million and
$28 million in 2005 and 2004, respectively, which were unrelated to transactions that occurred during those years. During 2006, Millennium reached agreement with U.K. tax authorities on issues related to a 1996 transaction with Hanson, whereas,
in 2005, Millennium had recognized an additional provision related to Hanson issues. During 2004, Millennium reached an agreement with the IRS concerning tax issues relating to the years 1993 through 1996. In connection with this agreement,
Millennium recorded net tax expense of $7 million in 2004, including the effect of the U.S. audit settlement on U.K. tax liabilities related to Millenniums tax sharing agreement with Hanson. Millennium recorded associated accruals of
interest expense of $29 million in 2005 and reversals of accrued interest of $29 million and $6 million in 2006 and 2004, respectively, related to income tax issues. The accrued interest reversals have been included in pre-tax income as
Other income (expense), net.

CommitmentsMillennium has various agreements for the purchase of ore used in the
production of TiO2and certain other agreements to purchase raw materials, utilities and services with various terms
extending through 2020. At December 31, 2006, estimated future minimum payments under these contracts with noncancelable contract terms in excess of one year were as follows:



|                    |  |     |     |       |   |       |  |   |

|Total               |  | $   | 253 |       | $ | 932   |  | $ | 1,185
|                    |  |     |     |       |   |       |  |   |      

Millenniums total purchases under these agreements were $331 million, $544 million
and $474 million, respectively, in 2006, 2005 and 2004.

Asset Retirement ObligationMillennium believes that there are
asset retirement obligations associated with some of its facilities, but that the present value of those obligations normally is not material in the context of an indefinite expected life of the facilities. Millennium continually reviews the optimal
future alternatives for its facilities. The amount and timing of costs, if any, that may be incurred as a result of such reviews are not known, and no decisions have been reached, but if a decision were reached, in accordance with local laws and
customs, to retire one or more facilities in the foreseeable future, the asset retirement costs could range from $0 to $30 million, depending upon the scope of the required work and other factors. At December 31, 2006, the balance of the
liability that had been recognized for all asset retirement obligations, including scheduled closure of certain landfills, was $12 million. In addition, any decision to retire a facility would result in other costs, including employment related
costs.

Environmental RemediationMillenniums accrued liability for future environmental remediation costs at current and
former plant sites and other remediation sites totaled $172 million and $168 million as of December 31, 2006 and 2005, respectively. The remediation expenditures are expected to occur over a number of years, and not to be concentrated
in any single year. In the opinion of management, there is no material estimable range of reasonably possible loss in excess of the liabilities recorded for environmental remediation. However, it is possible that new information about the sites
for which the accrual has been established, new technology or future developments such as involvement in investigations by regulatory agencies, could require Millennium to reassess its potential exposure related to environmental matters.

The following table summarizes the activity in Millenniums accrued environmental liability for the years ended December 31:

|--- | -------------------------------------------

The 2004 provision for estimated environmental remediation costs was $31 million. A substantial portion of these provisions was for the Kalamazoo River Superfund Site. The liabilities for individual sites range
from less than $1 million to $106 million. The $106 million liability relates to the Kalamazoo River Superfund Site.

A
Millennium subsidiary has been identified as a Potential Responsible Party (PRP) with respect to the Kalamazoo River Superfund Site. The site involves cleanup of river sediments and floodplain soils contaminated with polychlorinated
biphenyls, cleanup of former paper mill operations, and cleanup and closure of landfills associated with the former paper mill operations. In 2000, the Kalamazoo River Study Group (the KRSG), of which the Millennium subsidiary and other
PRPs are members, submitted to the State of Michigan a Draft Remedial Investigation and Draft Feasibility Study, which evaluated a number of remedial options for the river. The estimated costs for these remedial options ranged from $0 to
$2.5 billion.

At the end of 2001, the U.S. Environmental Protection Agency (EPA) took lead responsibility for the river
portion of the site at the request of the State of Michigan. In 2004, the EPA initiated a confidential process to facilitate discussions among the agency, the Millennium subsidiary, other PRPs, the Michigan Departments of Environmental Quality and
Natural Resources, and certain federal natural resource trustees about the need for additional investigation activities and different possible approaches for addressing the contamination in and along the Kalamazoo River. These discussions are
continuing.

As of December 31, 2006, the probable future remediation spending associated with the river cannot be determined
with certainty. Although the KRSG study identified a broad range of remedial options, not all of those options would represent reasonably possible outcomes. Management does not believe that it can identify a single remedy among those options that
would represent the highest-cost reasonably possible outcome. However, in 2004, Millennium recognized a liability representing Millenniums interim allocation of 55% of the $73 million total of estimated cost of riverbank stabilization,
recommended as the preferred remedy in 2000 by the KRSG study, and of certain other costs. At December 31, 2006, the balance of this liability was $58 million.

In addition, in 2004, Millennium recognized a liability primarily related to Millenniums estimated share of remediation costs for two former paper mill sites and associated landfills, which are also part of the
Kalamazoo River Superfund Site. At December 31, 2006, the balance of the liability was $48 million. Although no final agreement has been reached as to the ultimate remedy for these locations, Millennium has begun remediation activity
related to these sites.

Millenniums ultimate liability for the Kalamazoo River Superfund Site will depend on many factors that have
not yet been determined, including the ultimate remedy selected, the determination of natural resource damages, the number and financial viability of the other PRPs, and the determination of the final allocation among the PRPs.

At December 31, 2006, the balance of remediation liabilities related to Millennium sites other than the Kalamazoo River Superfund Site was
$66 million.

|--- | -------------------------------------------

LitigationTogether with alleged past manufacturers of lead-based paint and lead pigments for use in paint, Millennium has been named as a defendant in various legal proceedings alleging personal injury,
property damage, and remediation costs allegedly associated with the use of these products. The majority of these legal proceedings assert unspecified monetary damages in excess of the statutory minimum and, in certain cases, equitable relief such
as abatement of lead-based paint in buildings. Legal proceedings relating to lead pigment or paint are in various trial stages and post-dismissal settings, some of which are on appeal.

One legal proceeding relating to lead pigment or paint was tried in 2002. On October 29, 2002, the judge in that case declared a mistrial after the jury declared itself deadlocked. The sole
issue before the jury was whether lead pigment in paint in and on Rhode Island buildings constituted a public nuisance. The re-trial of this case began on November 1, 2005.On February 22, 2006, a jury returned a verdict
in favor of the State of Rhode Island finding that the cumulative presence of lead pigments in paints and coatings on buildings in the state constitutes a public nuisance; that a Millennium subsidiary, Millennium Holdings LLC, and other defendants
either caused or substantially contributed to the creation of the public nuisance; and that those defendants, including the Millennium subsidiary, should be ordered to abate the public nuisance. On February 28, 2006, the judge held that the
state could not proceed with its claim for punitive damages. As a result, the jury was discharged. The court has not entered a final judgment on the jurys verdict; however, on February 26, 2007, the court issued its decision denying the
post-verdict motions of the defendants, including Millennium, for a mistrial or a new trial. The court concluded that it would enter an order of abatement and appoint a special master to assist the court in determining the scope of the abatement
remedy.

Millenniums defense costs to date for lead-based paint and lead pigment litigation largely have been covered by insurance.
Millennium has insurance policies that potentially provide approximately $1 billion in indemnity coverage for lead-based paint and lead pigment litigation. Millenniums ability to collect under the indemnity coverage would depend upon,
among other things, the resolution of certain potential coverage defenses that the insurers are likely to assert and the solvency of the various insurance carriers that are part of the coverage block at the time of such a request.

While Millennium believes that it has valid defenses to all the lead-based paint and lead pigment proceedings and is vigorously defending them,
litigation is inherently subject to many uncertainties. Any liability that Millennium may ultimately incur, net of any insurance or other recoveries, cannot be estimated at this time.

United Kingdom Income TaxesIn 1996, in order to obtain clearance from the former United Kingdom Inland Revenue (currently Her Majestys Revenue and Customs) as to the tax-free
treatment of the demerger stock dividend for United Kingdom tax purposes for Hanson plc (Hanson) and Hansons shareholders, Hanson agreed with the United Kingdom Inland Revenue that Millennium would continue to be centrally managed
and controlled in the United Kingdom at least until September 30, 2001. Millennium agreed with Hanson 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. Effective February 4, 2002, Millennium ceased being centrally managed and controlled in the United Kingdom. Millennium believes
that it has satisfied all obligations that it be managed and controlled in the United Kingdom for the requisite five-year period. During 2006, Millennium received notice from Her Majestys Revenue and Customs that it had no further inquiries
with respect to this matter. See Note 17.

IndemnificationMillennium and its joint ventures are parties to various indemnification arrangements, including arrangements entered into in connection with acquisitions, divestitures and the formation of
joint ventures. For example, Millennium entered into indemnification arrangements in connection with its demerger from Hanson, and Equistar and its owner companies (including Millennium) entered into indemnification arrangements in connection with
the formation of Equistar. Pursuant to these arrangements, Millennium and its joint ventures provide indemnification to and/or receive indemnification from other parties in connection with liabilities that may arise in connection with the
transactions and in connection with activities prior to completion of the transactions. These indemnification arrangements typically include provisions pertaining to third party claims relating to environmental and tax matters and various types of
litigation. As of December 31, 2006, Millennium has not accrued any significant amounts for such indemnification obligations and is not aware of other circumstances that would be likely to lead to significant future indemnification claims
against Millennium. Millennium cannot determine with certainty the potential amount of future payments under the indemnification arrangements until events arise that would trigger a liability under the arrangements.

OtherMillennium and its joint ventures are, from time to time, defendants in lawsuits and other commercial disputes, some of which are not
covered by insurance. Many of these suits make no specific claim for relief. Although final determination of any liability and resulting financial impact with respect to any such matters cannot be ascertained with any degree of certainty, management
does not believe that any ultimate uninsured liability resulting from these matters in which it, its subsidiaries or its joint ventures currently are involved will, individually or in the aggregate, have a material adverse effect on the financial
position, liquidity or results of operations of Millennium.

GeneralIn the opinion of management, the matters discussed in
this note, other than potential future liabilities for environmental remediation which amounts cannot be estimated, are not expected to have a material adverse effect on the financial position or liquidity of Millennium. However, the adverse
resolution in any reporting period of one or more of the matters discussed in this note could have a material impact on Millenniums results of operations for that period, which may be mitigated by contribution or indemnification obligations of
others, or by any insurance coverage that may be available.



|19. | Stockholders Equity
|--- | --------------------

Preferred StockMillennium had authorized 1,000 shares of $.01 par value preferred stock at December 31, 2005 and 2004. In 2006, the reverse stock split discussed below, also removed the authorized preferred stock.

Common Stock In 2006, the Board of Directors of Millennium approved a 1 for 100,000 reverse stock split of the common stock
of Millennium, reducing the authorized shares from 100,000,000 shares to 1,000 shares and the issued and outstanding shares from 70,935,510 shares to 709 shares. The 709 shares include 48 shares held by Millennium America, a Millennium subsidiary,
which are accounted for as treasury stock in the Consolidated Balance Sheets. Millennium retained the current par value of $.01 per share of common stock. The financial statements reflect the effect of the reverse stock split for all periods
presented, resulting in a decrease in common stock and an increase in additional paid-in capital of approximately $1 million.

As a
result of Lyondells acquisition of Millennium on November 30, 2004, each then issued and outstanding share of Millenniums common stock, excluding shares held directly by Lyondell and Millennium, was converted to a right to receive
0.95 shares of Lyondell common stock in return for the cancellation of such shares. Substantially all of the approximately 66 million shares of the Millennium common stock outstanding immediately prior to the acquisition were converted to
Lyondell common stock.

Omnibus Incentive Compensation PlanMillenniums Incentive Compensation Plan (the
Omnibus Incentive Plan) provided for awards to employee and non-employee directors in the form of (i) stock options, including incentive stock options and non-qualified stock options, (ii) stock appreciation rights,
(iii) restricted shares, (iv) performance units, (v) performance shares, (vi) stock awards and (vii) cash based awards. During 2003, Millennium granted non-qualified stock option awards for 445,800 shares, to a limited
number of Millenniums executive officers and key employees. No compensation expense was recognized in 2006, 2005 and 2004 for such equity-related awards under this plan. In addition, in 2004, Millennium granted 91,500 shares of restricted
stock to a limited number of Millenniums officers and key employees. Compensation expense related to these grants was $2 million in 2004. No further grants will be made under this plan.

Millenniums Long Term Incentive Plan and Executive Long Term Incentive Plan provided for the award of shares of Millennium common stock to certain
management personnel and senior executives, respectively, if certain performance targets were achieved. The Executive Long Term Incentive Plan also provided for a cash award based on the total shareholder return of Millenniums common stock
when compared to total shareholder return of Millenniums peer group (companies in the Standard & Poors Chemical Composite Index) over a three-year period. Beginning in 2001, these awards were granted under the Omnibus Incentive
Plan by reference to the Long Term Incentive Plan. The obligations under these plans were funded by shares of Millenniums common stock that were held in trusts established for that purpose. No shares remained in the trusts at December 31,
2004. Compensation expense related to these plans for 2004 was $12 million. No further grants will be made under these plans.

Long
Term Stock Incentive PlanMillenniums Long Term Stock Incentive Plan (Stock Incentive Plan) provided for the following types of awards to its employees: (i) stock options, including incentive stock options and
non-qualified stock options, (ii) stock appreciation rights, (iii) restricted shares, (iv) performance units and (v) performance shares. All stock options awarded under this plan were granted at exercise prices equal to the
market price of Millenniums common stock. Compensation expense related to this plan was $2 million in 2004. No further grants will be made under this plan.

As a result of Lyondells acquisition of Millennium on November 30, 2004, each outstanding option under the Omnibus Incentive Compensation Plan and the Long Term Stock Incentive Plan to acquire Millennium
common stock was converted into an option to acquire 0.95 shares of Lyondell common stock. The exercise price of the converted option was the exercise price of the original Millennium option divided by the exchange ratio. All converted options
vested immediately pursuant to the change in control provisions of the plan. In addition, all unvested restricted stock vested immediately and was converted to 0.95 shares of Lyondell common stock.

Stock-based CompensationSFAS No. 123, Accounting for Stock-Based
Compensation, as amended by SFAS No. 148, Accounting for Stock-Based Compensation  Transition and Disclosure, encouraged, but did not require, a fair-value based method of accounting for employee stock options and similar
equity instruments, which generally would have resulted in the recording of additional compensation expense in Millenniums consolidated financial statements. Millennium accounted for stock-based employee compensation using the intrinsic value
method prescribed in APB Opinion No. 25 and related interpretations. Accordingly, no compensation cost was recognized for the stock option plans in the accompanying financial statements as all options granted had an exercise price equal to the
market value of the underlying common stock on the date of grant.

The pro forma effect on net loss before cumulative effect of accounting
change of measuring compensation expense for such grants in the manner prescribed in SFAS No. 123 is summarized in the table below for the year ended December 31, 2004:



|                                                                                             |  |   |     |

Salary and Bonus Deferral PlanMillennium had a deferred compensation plan under which
officers and certain management employees had deferred a portion of their compensation on a pre-tax basis in the form of shares of Millenniums common stock. A rabbi trust (the Trust) was established to hold shares of
Millenniums common stock purchased in open market transactions to fund this obligation. Shares purchased by the Trust were reflected as treasury stock, at cost, and, along with the related obligation for this plan, were included in
stockholders deficit. At November 30, 2004, the plan was no longer active; however, the Trust held 228,543 shares at a total cost of approximately $5 million. As a result of Lyondells acquisition of Millennium on
November 30, 2004, the shares of Millennium common stock held by the Trust were converted to shares of Lyondell common stock based on the exchange ratio of 0.95, and were paid out.

|22. | Subsequent Event
|--- | ----------------

On
February 23, 2007, Millennium signed an agreement for a proposed sale of Millenniums worldwide inorganic chemicals business for $1.05 billion, in cash, plus the assumption of specified liabilities. The amount will be adjusted up or down
depending on the change in value of net working capital, cash and specified indebtedness as of the closing date. Closing is anticipated to occur in the first half of 2007.

Beginning in the first quarter of 2007, the inorganic chemicals business segment will be reported as a discontinued operation, including comparative periods presented. Millenniums ongoing
operations will include the EC&D segment, consisting of the acetyls business and Millenniums equity investment in Equistar, and the fragrance and flavor chemicals business, which will become a reportable segment.

As of December 31, 2006, the affected assets and liabilities of the inorganic chemicals business are summarized as follows:



|                              |  |   |

|Item 9A. | Controls and Procedures
|-------- | -----------------------

Millennium performed an evaluation, under the supervision and with the participation of its management, including the Chief Executive Officer (principal executive officer) and the Senior Vice
President and Chief Financial Officer (principal financial officer), of the effectiveness of Millenniums disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as of
December 31, 2006. Based upon that evaluation, the Chief Executive Officer and the Senior Vice President and Chief Financial Officer concluded that Millenniums disclosure controls and procedures are effective.

There were no changes in Millenniums internal control over financial reporting that occurred during Millenniums last fiscal
quarter (the fourth quarter 2006) that have materially affected, or are reasonably likely to materially affect, Millenniums internal control over financial reporting.

Millenniums managements report on internal control over financial reporting appears on page 50 of this Annual Report on Form 10-K. In addition, PricewaterhouseCoopers LLP, the
independent registered public accounting firm that audited the financial statements included in this Annual Report on Form 10-K, has audited managements assessment of the effectiveness of Millenniums internal control over financial
reporting, as of December 31, 2006, as stated in their report that appears on page 51 of this Annual Report on Form 10-K.

Pre-Approval Policy

Generally, the Board of Directors of Millennium serves as
Millenniums Audit Committee, and is directly responsible for overseeing the work of the independent registered public accounting firm. However, as a result of Lyondells November 30, 2004 acquisition of Millennium, Millennium is now
a wholly-owned, consolidated subsidiary of Lyondell. Therefore, to protect the independence of Millenniums independent registered public accounting firm and to ensure that services provided by the independent registered public accounting firm
are pre-approved by an independent governing body, on December 1, 2004, Millenniums Board of Directors revised its pre-approval policy. Under the revised pre-approval policy, Millenniums Board of Directors has delegated to
Lyondells Audit Committee, which consists entirely of independent directors, the responsibility for reviewing and pre-approving all audit and non-audit services to be provided for Millennium by Millenniums independent registered public
accounting firm (including affiliates or related member firms).

Under the revised policy, a centralized service request
procedure is used for all requests for the independent registered public accounting firm to provide services to Millennium. Under this procedure, all requests for the independent registered public accounting firm to provide services to Millennium
initially are submitted to Lyondells Vice President and Controller. Each such request must include a detailed description of the services to be rendered. If the proposed services have not already been pre-approved by Lyondells Audit
Committee, Lyondells Vice President and Controller will submit the request and a detailed description of the proposed services to Lyondells Audit Committee. Requests to provide services that require pre-approval by Lyondells Audit
Committee also must include a statement as to whether, in the view of Lyondells Vice President and Controller, the request is consistent with the SECs rules on independent registered public accounting firm independence.

Pursuant to the revised policy, Millenniums Board of Directors has designated Lyondells Senior Vice President and Chief
Financial Officer to review compliance with the pre-approval policy. Lyondells Senior Vice President and Chief Financial Officer will report to Lyondells Audit Committee periodically on the results of the monitoring.

MANAGEMENTS REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

The management of Equistar is responsible for
establishing and maintaining adequate internal control over financial reporting. Equistars internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the
preparation of financial statements for external reporting in accordance with generally accepted accounting principles.

Equistar management assessed the
effectiveness of Equistars internal control over financial reporting as of December 31, 2006. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in
Internal ControlIntegrated Framework. Based on its assessment, Equistars management has concluded that Equistars internal control over financial reporting was effective as of December 31, 2006 based on those criteria.

PricewaterhouseCoopers LLP, the independent registered public accounting firm that audited the financial statements included in this Annual Report on Form
10-K, has audited managements assessment of the effectiveness of Equistars internal control over financial reporting as of December 31, 2006, as stated in their report that appears on the following page.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Partnership Governance Committee and Partners

of Equistar Chemicals, LP

We have completed integrated audits of Equistar
Chemicals, LPs consolidated financial statements and of its internal control over financial reporting as of December 31, 2006, in accordance with the standards of the Public Company Accounting Oversight Board (United States). Our opinions,
based on our audits, are presented below.

Consolidated financial statements

In our opinion, the consolidated financial statements listed in the accompanying index present fairly, in all material respects, the financial position of Equistar Chemicals, LP (the Partnership) and its
subsidiaries at December 31, 2006 and 2005, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2006 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 the standards of the Public Company Accounting Oversight Board (United States). 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 of financial statements 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.

As discussed in Note 2
to the consolidated financial statements, effective December 31, 2006, the Partnership changed its method of accounting for defined benefit pension and other postretirement plans.

Internal control over financial reporting

Also, in our opinion, managements assessment, included in
Managements Report on Internal Control Over Financial Reporting appearing under Item 8, that the Partnership maintained effective internal control over financial reporting as of December 31, 2006 based on criteria established in Internal
Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), is fairly stated, in all material respects, based on those criteria. Furthermore, in our opinion, the Partnership maintained,
in all material respects, effective internal control over financial reporting as of December 31, 2006, based on criteria established in Internal Control - Integrated Framework issued by the COSO. The Partnerships management is
responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting. Our responsibility is to express opinions on managements assessment and
on the effectiveness of the Partnerships internal control over financial reporting based on our audit. We conducted our audit of internal control over financial reporting in accordance with the standards of the Public Company Accounting
Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. An audit of
internal control over financial reporting includes obtaining an understanding of internal control over financial reporting, evaluating managements assessment, testing and evaluating the design and operating effectiveness of internal control,
and performing such other procedures as we consider necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinions.

A companys internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in
accordance with generally accepted accounting principles. A companys internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and
fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance

with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of
management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the companys assets that could have a material effect on the financial
statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of
any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

|1. | Formation of the Partnership and Operations
|-- | -------------------------------------------

Equistar Chemicals, LP
together with its consolidated subsidiaries (collectively, Equistar or the Partnership), a Delaware limited partnership which commenced operations on December 1, 1997, was formed by Lyondell Chemical Company and
subsidiaries (Lyondell) and Millennium Chemicals Inc. and subsidiaries (Millennium). On May 15, 1998, Equistar was expanded with the contribution of certain assets from Occidental Petroleum Corporation and subsidiaries
(Occidental). Prior to August 22, 2002, Equistar was owned 41% by Lyondell, 29.5% by Millennium and 29.5% by Occidental. On August 22, 2002, Lyondell purchased Occidentals interest in Equistar and, as a result,
Lyondells ownership interest in Equistar increased to 70.5%. Equistar became a wholly-owned subsidiary of Lyondell as a result of Lyondells acquisition of Millennium on November 30, 2004. The consolidated financial statements of
Equistar reflect its historical cost basis, and, accordingly, do not reflect any purchase accounting adjustments related to the acquisition by Lyondell of Millennium and Millenniums interest in Equistar or of Occidentals interest in
Equistar.

Equistar manufactures and markets ethylene and its co-products, primarily propylene, butadiene and aromatics. Equistar also manufactures and
markets fuel products and ethylene derivatives, primarily ethylene oxide, ethylene glycol and polyethylene.



|2. | Summary of Significant Accounting Policies
|-- | ------------------------------------------

Basis of
PresentationThe consolidated financial statements include the accounts of Equistar and its subsidiaries.

Revenue RecognitionRevenue
from product sales is recognized at the time of transfer of title and risk of loss to the customer, which usually occurs at the time of shipment. Revenue is recognized at the time of delivery if Equistar retains the risk of loss during shipment. For
products that are shipped on a consignment basis, revenue is recognized when the customer uses the product. Costs incurred in shipping products sold are included in cost of sales. Billings to customers for shipping costs are included in sales
revenue.

Cash and Cash EquivalentsCash equivalents consist of highly liquid debt instruments such as certificates of deposit, commercial
paper and money market accounts. Cash equivalents include instruments with maturities of three months or less when acquired. Cash equivalents are stated at cost, which approximates fair value. Equistars policy is to invest cash in
conservative, highly rated instruments and to limit the amount of credit exposure to any one institution.

Equistar has no requirements for compensating
balances in a specific amount at a specific point in time. Equistar 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.

Allowance for Doubtful AccountsEquistar establishes provisions for doubtful accounts receivable based on managements estimates of
amounts that it believes are unlikely to be collected. Collectability of receivables is reviewed and the allowance for doubtful accounts is adjusted at least quarterly, based on aging of specific accounts and other available information about the
associated customers.

InventoriesInventories are stated at the lower of cost or market. Cost is determined using the last-in, first-out
(LIFO) method for substantially all inventories, except for materials and supplies, which are valued using the average cost method.

|2. | Summary of Significant Accounting Policies  (Continued)
|-- | --------------------------------------------------------

Inventory exchange transactions, which involve fungible commodities 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 LIFO valuation policy.

Property, Plant and EquipmentProperty, plant and equipment are recorded at cost. Depreciation
is computed using the straight-line method over the estimated useful asset lives, generally 25 years for major manufacturing equipment, 30 years for buildings, 5 to 15 years for light equipment and instrumentation, 15 years for office furniture and
3 to 5 years for information systems equipment. Upon retirement or sale, Equistar 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. Equistars policy is to capitalize interest cost incurred on debt during the construction of major projects exceeding one year.

Long-Lived
Asset ImpairmentEquistar evaluates long-lived assets, including identifiable intangible assets, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. When it is
probable that undiscounted future cash flows will not be sufficient to recover an assets carrying amount, the asset is written down to its estimated fair value.

InvestmentsEquistars investments primarily consist of a 50% interest in a joint venture that owns an ethylene glycol facility in Beaumont, Texas (PD Glycol). The investment in PD Glycol
is accounted for using the equity method.

Identifiable Intangible AssetsCosts to purchase and to develop software for internal use are
deferred and amortized on a straight-line basis over periods of 3 to 10 years.

Costs of maintenance and repairs exceeding $5 million incurred as part of
turnarounds of major units at Equistars manufacturing facilities are deferred and amortized using the straight-line method over the period until the next planned turnaround, predominantly 4 to 7 years. These costs are necessary to maintain,
extend and improve the operating capacity and efficiency rates of the production units.

Other intangible assets are carried at cost or amortized cost and
primarily consist of deferred debt issuance costs, patents and license costs, 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
over the term of the related agreement, if shorter.

Environmental Remediation CostsAnticipated expenditures related to investigation and
remediation of contaminated sites, which include current and former plant sites and other remediation sites, are accrued when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated. Only ongoing
operating and monitoring costs, the timing of which can be determined with reasonable certainty, are discounted to present value. Future legal costs associated with such matters, which generally are not estimable, are not included in these
liabilities.

Legal CostsEquistar expenses legal costs, including those incurred in connection with loss contingencies, as incurred.

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.

|2. | Summary of Significant Accounting Policies  (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, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amount of revenues and expenses during the reporting periods. Actual results could differ from those estimates.

ReclassificationsCertain previously reported amounts have been reclassified to conform to classifications adopted in 2006.

Accounting and Reporting ChangesEffective December 31, 2006, Equistar adopted the provisions of Statement of Financial Accounting Standards
(SFAS) No. 158, Employers Accounting for Defined Benefit Pension and Other Postretirement Plans-An Amendment of FASB Statements No. 87, 88, 106, and 132R, which primarily requires an employer to recognize in its
statement of financial position an asset for a plans overfunded status or a liability for a plans underfunded status through comprehensive income in the year in which changes occur. Equistars application of SFAS No. 158 as of
December 31, 2006 resulted in increases of $6 million and $8 million in its current and long-term benefit liabilities, respectively, a decrease of $9 million in other assets and an increase of $23 million in accumulated other
comprehensive loss in its consolidated balance sheet as of December 31, 2006. (See Note 15)

In September 2006, the Financial Accounting Standards
Board (FASB) issued SFAS No. 157, Fair Value Measurements. The new standard defines fair value, establishes a framework for its measurement and expands disclosures about such measurements. For Equistar, the standard will be
effective beginning in 2008. Equistar does not expect the application of SFAS No. 157 to have a material effect on its consolidated financial statements.

Effective January 1, 2006, Equistar adopted the provisions of SFAS No. 123 (revised 2004), Share-Based Paymentusing the modified prospective method and, consequently, has not adjusted results of prior periods. Equistar
previously accounted for these plans according to the provisions of SFAS No. 123, Accounting for Stock-Based Compensation.Equistars application of SFAS No. 123 (revised 2004) had no material effect on its consolidated
financial statements.

Effective April 1, 2006, Equistar adopted the provisions of Emerging Issues Task Force (EITF) Issue No. 04-13,
Accounting for Purchases and Sales of Inventory with the Same Counterparty. EITF Issue No. 04-13, requires that inventory purchases and sales transactions with the same counterparty that are entered into in contemplation of one another
be combined for purposes of applying Accounting Principles Board Opinion No. 29, Accounting for Nonmonetary Transactions. The effect of this requirement is to reduce reported revenues and cost of sales for affected transactions.
Equistars application of EITF Issue No. 04-13 had no material effect on its consolidated financial statements.



|3. | Asset Impairment
|-- | ----------------

Equistars 2006 earnings reflect a charge of
$135 million for impairment of the net book value of its idled Lake Charles, Louisiana ethylene facility. In the third quarter of 2006, Equistar undertook a study of the feasibility, cost and time required to restart the Lake Charles ethylene
facility. As a result, management determined that restarting the facility would not be justified. The remaining net book value of the related assets of $10 million represents an estimate, based on probabilities, of alternative-use value. Equistar
does not expect to incur any significant future costs with respect to the facility.

|4. | Hurricane Effects
|-- | -----------------

During 2005, two major hurricanes impacted the
chemical and related industries in the coastal and off-shore regions of the Gulf of Mexico. Net income in 2005 reflected charges totaling $28 million representing Equistars exposure to industry losses expected to be underwritten by
industry insurance consortia, primarily resulting from hurricane damages.

As a result of Hurricane Rita, Equistar also incurred various costs that are
subject to insurance reimbursements. Such costs include those incurred in conjunction with suspending operations at substantially all of its Gulf Coast plants, minor damage to facilities, and costs to restore operations. Net income in 2005 included
$19 million of such costs incurred by Equistar, of which all but a $5 million deductible under the relevant insurance policies are subject to reimbursement through insurance. In 2006, Equistar recognized a $1 million benefit from
insurance reimbursements related to its plants. No benefits were recognized in 2005.



|5. | Related Party Transactions
|-- | --------------------------

Equistar is a wholly-owned subsidiary
of Lyondell. As of December 31, 2006 and giving effect to Occidentals January 26, 2007 exercise of its warrant to purchase Lyondell common stock, Occidental owned 8.5% of Lyondell, and had one representative on the Lyondell Board of
Directors. Lyondell owns 100% of Houston Refining LP (formerly known as LYONDELL-CITGO Refining LP) and Millennium. All of the above companies are considered related parties of Equistar. In the discussion of related party transactions below,
Lyondell refers to Lyondell Chemical Company and its wholly-owned subsidiaries other than Houston Refining, Millennium and Equistar and their respective subsidiaries.

Product Transactions with LyondellLyondell purchases ethylene, propylene and benzene at market-related prices from Equistar under various agreements expiring in 2013 and 2014. With the exception of one
pre-existing third-party product supply agreement expiring in 2015, Lyondell is required, under the agreements, to purchase 100% of its ethylene, propylene and benzene requirements for its Channelview and Bayport, Texas facilities from Equistar.
Lyondell licenses methyl tertiary butyl ether (MTBE) technology to Equistar, and purchases MTBE produced by Equistar at market-related prices.

Through December 31, 2004, Equistar acted as sales agent for the methanol products of Lyondell. Equistar also provided operating and other services for Lyondell including the lease to Lyondell by Equistar of the real property on which
the methanol plant was located. Pursuant to the terms of the agreement, Lyondell paid Equistar a management fee and reimbursed certain expenses of Equistar at cost.

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 from Equistar. The initial term of the contract expired December 31, 2000 and it continues thereafter for one-year periods unless either party
serves notice of termination twelve months in advance.

Equistar is required to purchase 100% of its vinyl acetate monomer raw material requirements at
market-related prices from Millennium for the production of ethylene vinyl acetate products at its LaPorte, Texas; Clinton, Iowa and Morris, Illinois plants, and 100% of its glacial acetic acid requirements at market-related prices from Millennium
for the production of glycol ether acetate at its Bayport, Texas plant. The initial terms of these agreements expired December 31, 2005 and continue year to year thereafter unless terminated by either party.

|5. | Related Party Transactions  (Continued)
|-- | ----------------------------------------

Product
Transactions with OccidentalEquistar and Occidental entered into an ethylene sales agreement on May 15, 1998, which was amended effective April 1, 2004, pursuant to which Occidental agreed to purchase a substantial amount of its
ethylene raw material requirements from Equistar. Either party has the option to phase down volumes over time. However, a phase down cannot begin until January 1, 2014 and the annual minimum requirements cannot decline
to zero prior to December 31, 2018, unless certain specified force majeure events occur. In addition to the sales of ethylene, from time to time Equistar has made sales of ethers and glycols to Occidental, and Equistar has purchased various
other products from Occidental, all at market-related prices.

Product Transactions with Houston Refining LPEquistar has product sales and raw
material purchase agreements with Houston Refining, a wholly-owned subsidiary of Lyondell as of August 16, 2006. Certain ethylene co-products are sold by Equistar to Houston Refining for processing into gasoline and certain refined products are
sold by Houston Refining to Equistar as raw materials. Equistar also has processing and storage arrangements with Houston Refining and provides certain marketing services for Houston Refining. All of the agreements between Houston Refining and
Equistar are on terms generally representative of prevailing market prices. Subsequent to August 16, 2006, transactions between Equistar and Houston Refining are reported as related party transactions of Lyondell.

Shared Services Agreement with LyondellUnder a shared services agreement, Lyondell provides office space and various services to Equistar, including
information technology, sales and marketing, supply chain, and other administrative and support services. Lyondell charges Equistar for Equistars share of the cost of such services. Direct costs, incurred exclusively for Equistar, also are
charged to Equistar. Costs related to a limited number of shared services, primarily engineering, continue to be incurred by Equistar on behalf of Lyondell. In such cases, Equistar charges Lyondell for its share of such costs.

Shared Services and Shared-Site Agreements with MillenniumEquistar and Millennium provide operating services, utilities and raw materials to each other at
common locations. Millennium and Equistar have various operating, manufacturing and technical service agreements under which, Millennium bills Equistar for certain operational services, including utilities, plant-related transportation and other
services, and Equistar bills Millennium for utilities and fuel streams.

Lease Agreements with OccidentalEquistar subleases certain railcars
from Occidental and leases its Lake Charles ethylene facility and the land related thereto from Occidental. See Note 3 for additional information related to the Lake Charles ethylene facility.

|6. | Accounts Receivable
|-- | -------------------

Equistar sells its products primarily to other
chemical manufacturers in the petrochemical industry. Equistar performs ongoing credit evaluations of its customers financial condition and, in certain circumstances, requires letters of credit from them. Equistars allowance for doubtful
accounts receivable, which is reflected in the Consolidated Balance Sheets as a reduction of accounts receivable, totaled $5 million and $7 million at December 31, 2006 and 2005, respectively. The Consolidated Statements of Income
included provisions for doubtful accounts of less than $1 million in each of 2006 and 2004. There were no provisions for doubtful accounts receivable in 2005.

|6. | Accounts Receivable  (Continued)
|-- | ---------------------------------

In November 2005, Equistar
amended its $450 million accounts receivable sales facility, increasing the commitment to $600 million and extending the maturity to November 2010. Pursuant to this facility, Equistar sells, through a wholly-owned bankruptcy-remote subsidiary, on an
ongoing basis and without recourse, an interest in a pool of domestic accounts receivable to financial institutions participating in the facility. Equistar is responsible for servicing the receivables. The $600 million accounts receivable sales
facility is subject to substantially the same minimum unused availability requirements and covenant requirements as the $400 million inventory-based revolving credit facility, which also is secured by a pledge of accounts receivable (see Note 12).

The amount of the interest in the pool of receivables permitted to be sold is determined by a formula. Accounts receivable in the Consolidated Balance
Sheets are reduced by the sales of interests in the pool. Upon termination of the facility, cash collections related to accounts receivable then in the pool would first be applied to the outstanding interests sold. Increases and decreases in the
amount sold are reflected in operating cash flows in the Consolidated Statements of Cash Flows, representing collections of sales revenue. Fees related to the sales are included in Selling, general and administrative expenses in the
Consolidated Statements of Income. The outstanding amount of receivables sold under the facility was $200 million as of December 31, 2005 and there was none outstanding as of December 31, 2006.

Prior to January 2006, discounts were offered to certain customers for early payment for product. As a result, some receivable amounts were collected in December 2005
and 2004, respectively, that otherwise would have been expected to be collected in January 2006 and 2005, respectively. This included collections of $84 million and $66 million in December 2005 and 2004, respectively, related to
receivables from Occidental.



|7. | Inventories
|-- | -----------

Inventories consisted of the following components at
December 31:



|                       |  |      |     |      |   |    
|---------------------- |  | ---- | --- | ---- | - | ---

|Total inventories      |  | $    | 809 |      | $ | 657
|                       |  |      |     |      |   |    

At December 31, 2006, approximately 89% of Equistars inventories, excluding materials and supplies and
in-transit inventory, were valued using the LIFO method.

The excess of the current replacement cost over book value of those inventories that are carried
at cost using the LIFO method was approximately $381 million and $465 million at December 31, 2006 and 2005, respectively.

Equistars
inventory-based revolving credit facility was amended in November 2005, increasing the availability from $250 million to $400 million and extending the maturity to November 2010. This facility was undrawn at December 31, 2006 and 2005 (see Note
12).

Maintenance and repair expenses were $287 million, $261 million and $246 million for the years
ended December 31, 2006, 2005 and 2004, respectively. No interest was capitalized to property, plant and equipment during the three-year period.

In
2004, Equistar sold certain railcars for $37 million and leased the railcars from the buyer under an operating lease agreement. The sale resulted in a gain of $7 million that is being recognized over the 10 year term of the lease as a
reduction of lease rent expense.

Aggregate maturities of all long-term debt during the next five years are $700 million in 2008,
$600 million in 2009, $3 million in 2010, $707 million in 2011 and $150 million thereafter.

Equistar may currently redeem its 10.125%
Senior Notes due 2008, 10.625% Senior Notes due 2011 and 8.75% Notes due 2009 upon payment of the present value of future interest and principal amounts, using a specified discount rate. Alternatively, Equistar may redeem the 10.625% Senior Notes
due 2011 beginning in 2007, at a price of 105.313% of the principal amount with the price declining annually to 100% at maturity.

During 2006, Equistar
repaid the $150 million of 6.5% Notes outstanding, which matured in February 2006.

During 2005, Equistar amended its $250 million
inventory-based revolving credit facility, increasing the availability to $400 million, extending the maturity to November 2010 and reducing the interest rate from LIBOR plus 2.25% to LIBOR plus 1.5%. The total amount available at
December 31, 2006 under both the $400 million inventory-based revolving credit facility and the $600 million accounts receivable sales facility (see Note 6) was $938 million, which gave effect to the borrowing base less a
$50 million unused availability requirement and any outstanding amount of accounts receivable sold under the accounts receivable facility, of which there was none at December 31, 2006, and $12 million of outstanding letters of credit
under the revolving credit facility as of December 31, 2006. The borrowing base is determined using a formula applied to accounts receivable and inventory balances. The revolving credit facility requires that the unused available amounts under
that facility and the $600 million accounts receivable sales facility equal or exceed $50 million, or $100 million if the Interest Coverage Ratio (as defined) at the end of any period of four consecutive fiscal quarters is less than
2:1. The revolving credit facility is secured by a lien on all inventory and certain personal property, including a pledge of accounts receivable. There was no borrowing under the revolving credit facility at December 31, 2006.

|12. | Long-Term Debt  (Continued)
|--- | ----------------------------

The $400 million revolving
credit facility and the indentures contain covenants that, subject to exceptions, restrict, among other things, lien incurrence, debt incurrence, dividends, sales of assets, investments, accounts receivable securitizations, purchase of equity,
payments on indebtedness, affiliate transactions, sale and leaseback transactions and mergers. The credit facility does not require the maintenance of specified financial ratios as long as certain conditions are met. In addition, some of
Equistars indentures require additional interest payments to the note holders if Equistar makes distributions when its Fixed Charge Coverage Ratio (as defined) is less than 1.75 to 1.

Lyondell is a guarantor of Equistars 7.55% Debentures due 2026. 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, 2006.



|13. | Lease Commitments
|--- | -----------------

Equistar leases various facilities and equipment
under noncancelable operating lease arrangements for varying periods. Operating leases include leases of railcars used in the distribution of products in Equistars business. As of December 31, 2006, future minimum lease payments for the
next five years and thereafter, relating to all noncancelable operating leases with lease terms in excess of one year were as follows:

|                             |  |   |    
|Total minimum lease payments |  | $ | 703
|                             |  |   |    

Net rental expense for 2006, 2005 and 2004 was $106 million, $103 million and $94 million,
respectively.



|14. | Financial Instruments and Derivatives
|--- | -------------------------------------

The fair value of all
nonderivative financial instruments included in current assets and current liabilities, including cash and cash equivalents, accounts receivable and accounts payable, 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
$2,255 million and $2,456 million at December 31, 2006 and 2005, respectively.

|15. | Pension and Other Postretirement Benefits
|--- | -----------------------------------------

All full-time regular
employees are covered by defined benefit pension plans sponsored by Equistar. Retirement benefits are generally based upon years of service and the employees highest compensation for any consecutive 36 month period during the last 120
months of service or other compensation measures as defined under the respective plan provisions. Equistar funds the plans through contributions to pension trust funds, generally subject to minimum funding requirements as provided by applicable law.
Equistar also has unfunded supplemental nonqualified retirement plans, which provide pension benefits for certain employees in excess of the U.S. tax-qualified plans limits. In addition, Equistar sponsors unfunded postretirement benefit plans
other than pensions, which provide medical and life insurance benefits. The postretirement medical plans are contributory, while the life insurance plans are generally non contributory. The life insurance benefits are provided to employees who
retired before July 1, 2002.

The assumed annual rate of increase in the per capita cost of covered health care benefits as of December 31,
2006 was 10% for 2007, decreasing 1% per year to 5% in 2012 and thereafter. The health care cost trend rate assumption does not have a significant effect on the amounts reported due to limits on Equistars maximum contribution level to the
medical plan. To illustrate, increasing or decreasing the assumed health care cost trend rates by one percentage point in each year would change the accumulated other postretirement benefit liability as of December 31, 2006 by less than
$1 million and would not have a material effect on the aggregate service and interest cost components of the net periodic other postretirement benefit cost for the year then ended.

Managements goal is to manage pension investments over the long term to achieve optimal returns with an acceptable level of risk and volatility. Targeted asset allocations of 55% U.S. equity securities, 15%
non-U.S. equity securities, and 30% fixed income securities are based on recommendations by Equistars independent pension investment advisor. Equistars expected long-term rate of return on plan assets of 8% is based on the average level
of earnings that its independent pension investment advisor has advised could be expected to be earned over time on such allocation. Investment policies prohibit investments in securities issued by Equistar or an affiliate, such as Lyondell or
Millennium, or investment in speculative derivative instruments. The investments are marketable securities that provide sufficient liquidity to meet expected benefit obligation payments.

Equistar also maintains voluntary defined contribution savings plans for eligible employees. Contributions to the
plans by Equistar were $13 million in 2006 and $12 million in each of 2005 and 2004.



|16. | Commitments and Contingencies
|--- | -----------------------------

CommitmentsEquistar has
various purchase commitments for materials, supplies and services incident to the ordinary conduct of business, generally for quantities required for its businesses and at prevailing market prices. Equistar is also a party to various obligations to
purchase products and services, principally for utilities and industrial gases. These commitments are designed to assure sources of supply and are not expected to be in excess of normal requirements. See also Note 5, describing related party
transactions. At December 31, 2006, future minimum payments under those contracts with noncancelable contract terms in excess of one year and fixed minimum payments were as follows:

|16. | Commitments and Contingencies  (Continued)
|--- | -------------------------------------------

Equistars
total purchases under these agreements were $416 million, $494 million and $378 million for the years ended December 31, 2006, 2005 and 2004, respectively.

Asset Retirement ObligationEquistar believes that there are asset retirement obligations associated with some of its facilities, but that the present value of those obligations normally is not material in
the context of an indefinite expected life of the facilities. Equistar continually reviews the optimal future alternatives for its facilities. In many cases, the amount and timing of costs, if any, that may be incurred as a result of such reviews
are not known, and no decisions have been reached, but if a decision were reached to retire one or more facilities in the foreseeable future, the asset retirement costs could range from $0 to $30 million, depending upon the scope of the
required work and other factors. At December 31, 2006, the balance of the liability that had been recognized for all asset retirement obligations was $12 million. In addition, any decision to retire a facility would result in other costs,
including employment related costs.

Environmental RemediationEquistars accrued liability for future environmental remediation costs
totaled $4 million and $1 million as of December 31, 2006 and 2005, respectively. In the opinion of management, there is no material estimable range of reasonably possible loss in excess of the liability recorded for environmental
remediation. However, it is possible that new information about the sites for which the accrual has been established, new technology or future developments such as involvement in investigations by regulatory agencies, could require Equistar to
reassess its potential exposure related to environmental matters.

MTBEThe presence of MTBE in some water supplies in certain U.S. states due
to gasoline leaking from underground storage tanks and in surface water from recreational water craft led to public concern about the use of MTBE and resulted in U.S. federal and state governmental initiatives to reduce or ban the use of MTBE.
Substantially all refiners and blenders have discontinued the use of MTBE in the U.S.

Accordingly, Equistars MTBE is sold for use outside of the
U.S. However, there are higher distribution costs and import duties associated with exporting MTBE outside of the U.S., and the increased supply of MTBE may reduce profitability of MTBE in these export markets. Should it become necessary or
desirable to significantly reduce MTBE production, Equistar may make capital expenditures to add the flexibility to produce alternative gasoline blending components, such as iso-octane, iso-octene (also know as di-isobutylene) or ethyl
tertiary butyl ether (ETBE), at its MTBE plant. Conversion and product decisions will continue to be influenced by regulatory and market developments. The profit contribution related to iso-octane or iso-octene may be lower than
that historically realized on MTBE.

OtherEquistar is, from time to time, a defendant in lawsuits and other commercial disputes, some of which
are not covered by insurance. Many of these suits make no specific claim for relief. Although final determination of any liability and resulting financial impact with respect to any such matters cannot be ascertained with any degree of certainty,
management does not believe that any ultimate uninsured liability resulting from these matters in which it currently is involved will, individually or in the aggregate, have a material adverse effect on the financial position, liquidity or results
of operations of Equistar.

GeneralIn the opinion of management, the matters discussed in this note are not expected to have a material
adverse effect on the financial position or liquidity of Equistar. However, the adverse resolution in any reporting period of one or more of these matters could have a material impact on Equistars results of operations for that period, which
may be mitigated by contribution or indemnification obligations of others, or by any insurance coverage that may be available.

Supplemental cash flow
information is summarized as follows for the years ended December 31:



|                       |  |      |     |      |   |      |  |   |

|                       |  |      |     |      |   |      |  |   |    



|18. | Segment and Related Information
|--- | -------------------------------

Equistar operates in one
reportable segment, ethylene, co-products and derivatives (EC&D), which includes: the ethylene and co-products product group, including primarily manufacturing and marketing of ethylene, its co-products, including propylene,
butadiene and aromatics; and the derivatives product group, including primarily manufacturing and marketing of ethylene oxide, ethylene glycol and polyethylene (see Note 1).

The accounting policies of the segment are the same as those described in Summary of Significant Accounting Policies (see Note 2). Transfers of product from the ethylene and co-products product group to
the derivatives product group are made at prices approximating prevailing market prices. No trade customer accounted for 10% or more of Equistars consolidated sales during any year in the three-year period ended December 31, 2006;
however, sales to Lyondell were approximately 11% in 2006 and 10% in each of 2005 and 2004.
