                                    SUMMARY

    This section highlights some of the information contained or incorporated by
reference in this prospectus. Because this is only a summary, it may not include
all the information that is important to you. To understand this exchange offer,
you should read the entire prospectus, especially Risk Factors, and the
documents incorporated by reference before making a decision. Unless the context
requires otherwise, in this prospectus the terms 'we,' 'us' and 'our' refer to
Millennium America together with its consolidated subsidiaries, and the term
'Millennium Chemicals' refers to Millennium Chemicals Inc., the indirect parent
of Millennium America and the guarantor of the outstanding registered and
unregistered notes and the exchange notes offered hereby, and its consolidated
subsidiaries.

                           MILLENNIUM CHEMICALS INC.

    Millennium Chemicals is a major international chemical company, with leading
market positions in a broad range of commodity, industrial, performance and
specialty chemicals.

    Millennium Chemicals has three business segments: Titanium Dioxide and
Related Products; Acetyls; and Specialty Chemicals. Millennium Chemicals also
owns a 29.5% interest in Equistar Chemicals, LP, a joint venture owned by
Millennium Chemicals and Lyondell Chemical Company. Millennium Chemicals
accounts for its interest in Equistar as an equity investment.

    Millennium Chemicals has leading market positions in the United States and
the world:

     Through Millennium Chemicals' Titanium Dioxide and Related Products
     business segment, it is the second-largest producer of titanium dioxide, or
     TiO[u]2, in the world, with manufacturing facilities in the United States,
     the United Kingdom, France, Brazil and Australia. It is also the largest
     merchant seller of titanium tetrachloride, or TiCl[u]4, in North America
     and Europe and a producer of zirconia, silica gel and cadmium-based
     pigments;

     Through Millennium Chemicals' Acetyls business segment, it is the
     second-largest producer of vinyl acetate monomer, or VAM, and acetic acid
     in North America and, through our 85% interest in La Porte Methanol Company
     LP ('La Porte Methanol Company'), a partner in a U.S. producer of methanol;

     Through Millennium Chemicals' Specialty Chemicals business segment, it is a
     leading producer of terpene-based fragrance and flavor chemicals; and

     of polyethylene in North America, and a leading producer of performance
     polymers, oxygenated chemicals, aromatics and specialty petrochemicals.

    References to Millennium Chemicals' and Equistar's market positions, with
the exception of Millennium Chemicals' market position in the Specialty
Chemicals business segment, are based on estimates of their respective
production capacities, as compared to the production capacities of other
industry participants. The reference to Millennium Chemicals' market position
with respect to the Specialty Chemicals business segment is based on sales
volumes of the Specialty Chemicals business segment, as compared to the
estimated sales volumes of its competitors.

    Estimates of the production capacities of Millennium Chemicals and Equistar
are based upon engineering assessments by Millennium Chemicals and Equistar,
respectively, and estimates of the production capacities (and sales volumes) of
other industry participants are based on publicly available information from a
variety of industry sources. Actual production may vary depending on a number of
factors including feedstocks, product mix, unscheduled maintenance and demand.

exchange offer must deliver a prospectus in any resale of the exchange notes. By
delivering a prospectus, a broker-dealer will not be deemed to admit that it is
an 'underwriter' within the meaning of the Securities Act. This prospectus, as
it may be amended or supplemented from time to time, may be used by a
broker-dealer in connection with the resales of exchange notes received in
exchange for outstanding unregistered notes where such outstanding unregistered
notes were acquired by such broker-dealer as a result of market-making
activities or other trading activities. Millennium America has agreed that, for
a period of 180 days after the expiration date, it will make this prospectus
available to any broker-dealer for use in connection with any such resale. See

                                  THE OFFERING

    We previously issued $375,000,000 aggregate principal amount of 9 1/4%
Senior Notes due 2008. On April 25, 2003, we completed the offering of an
additional $100 million aggregate principal amount of 9 1/4% Senior Notes due
2008 under the same indenture in a transaction that was exempt from registration
under the Securities Act. We used the gross proceeds of $109 million from the
April 2003 note offering to repay $85 million of outstanding indebtedness under
the revolving credit facility of our bank credit agreement and have allocated
the balance for general corporate purposes. The following is a brief summary of
the April 2003 offering.


                                    
Outstanding unregistered
  notes..............................  We sold the outstanding unregistered notes to J.P. Morgan
                                       Securities Inc., Banc of America Securities LLC, BNP Paribas
                                       Securities Corp., Credit Lyonnais Securities (USA) Inc.,
                                       Daiwa Securities SMBC Europe Limited and SG Cowen Securities
                                       Corporation, the initial purchasers, on April 25, 2003. The
                                       initial purchasers subsequently resold those notes to
                                       qualified institutional buyers pursuant to Rule 144A under
                                       the Securities Act and to non-U.S. persons outside the
                                       United States in reliance on Regulation S under the
                                       Securities Act.

Registration rights agreement........  In connection with the issuance of the outstanding
                                       unregistered notes, we and Millennium Chemicals entered into
                                       a registration rights agreement with the initial purchasers
                                       of those notes. Under the terms of that agreement we agreed
                                       to:

                                           file with the SEC on or before July 24, 2003 a
                                           registration statement for the exchange offer and the
                                           exchange notes;

                                           use our reasonable efforts to cause that registration
                                           statement to become effective under the Securities Act
                                           on or before October 22, 2003 a registration statement
                                           for the exchange offer and the exchange notes; and

                                           complete the exchange offer on or before November 21,
                                           2003.

                                       If we do not meet any of these requirements, we must pay
                                       liquidated damages to the holders of the outstanding
                                       unregistered notes until we meet the requirement. We have
                                       also agreed to keep the registration statement for the
                                       exchange offer effective for at least 30 days (or longer, if
                                       required by applicable law) after the date for which notice
                                       of the exchange offer is mailed to holders of notes. The
                                       exchange offer is being made pursuant to the registration
                                       rights agreement and is intended to satisfy the rights
                                       granted under the registration rights agreement, which

                                        THE EXCHANGE OFFER

    The following is a brief summary of the terms of the exchange offer. For a more complete
description of the exchange offer, see 'The Exchange Offer' in this prospectus.

Securities offered...................  $100,000,000 aggregate principal amount of 9 1/4% Senior
                                       Notes due 2008.

Exchange offer.......................  We are offering to exchange $1,000 principal amount of our
                                       9 1/4% Senior Notes due 2008, which have been registered
                                       under the Securities Act, for each $1,000 principal amount
                                       of our currently outstanding unregistered 9 1/4% Senior
                                       Notes due 2008. We will accept any and all outstanding
                                       unregistered notes validly tendered and not withdrawn prior
                                       to 5:00 p.m., New York City time on          , 2003. Holders
                                       may tender some or all of their unregistered notes pursuant
                                       to the exchange offer. However, unregistered notes may be
                                       tendered only in integral multiples of $1,000. The form and
                                       terms of the exchange notes are the same as the form and
                                       terms of the unregistered notes except that:

                                           the exchange notes have been registered under the
                                           Securities Act and will not bear any legend restricting
                                           their transfer;

                                           the exchange notes bear a different CUSIP number from
                                           the unregistered notes; and

                                           the holders of the exchange notes will not be entitled
                                           to certain rights under the registration rights
                                           agreement, including the provisions for liquidated
                                           damages on the outstanding unregistered notes in some
                                           circumstances relating to the timing of the exchange
                                           offer.

Transferability of exchange notes....  We believe, based on an interpretation by the staff of the
                                       SEC outlined in a series of no-action letters issued to
                                       third parties, that you will be able to freely transfer the
                                       exchange notes without registration or any prospectus
                                       delivery requirement so long as you may accurately make the
                                       representations listed under 'The Exchange
                                       Offer -- Transferability of Exchange Notes.' If you are a
                                       broker-dealer that acquired outstanding unregistered notes
                                       as a result of market-making or other trading activities,
                                       you must deliver a prospectus in connection with any resale
                                       of the exchange notes. See 'Plan of Distribution.'

Expiration date......................  The exchange offer will expire at 5:00 p.m., New York City
                                       time, on               , 2003, unless we, in our sole
                                       discretion, extend the exchange offer.

Conditions to the exchange offer.....  Notwithstanding any other term of the exchange offer, we
                                       shall not be required to accept for exchange, or exchange
                                       any exchange notes for, any outstanding unregistered notes,
                                       and may terminate or amend the exchange offer as provided in
                                       this prospectus before the acceptance of outstanding
                                       unregistered notes, if certain events occur, including the
                                       following:

                                           the exchange notes to be received will not be tradable
                                           by the holder without restrictions under the Securities
                                           Act or

                                           the Exchange Act and without material restrictions under
                                           the blue sky or securities laws of substantially all of
                                           the states of the United States;

                                           any action or proceeding is instituted or threatened in
                                           any court or by or before any governmental agency with
                                           respect to the exchange offer which, in our sole
                                           judgment, might materially impair our ability to proceed
                                           with the exchange offer or materially impair the
                                           contemplated benefits of the exchange offer to us;

                                           any law, statute, rule, regulation or interpretation by
                                           the staff of the SEC is proposed, adopted or enacted,
                                           which, in our sole judgment, might impair our ability to
                                           proceed with the exchange offer or impair the
                                           contemplated benefits of the exchange offer to us; or

                                           any governmental approval has not been obtained, which
                                           we believe, in our sole discretion, is necessary for the
                                           consummation of the exchange offer as outlined in this
                                           prospectus.

                                           you are not acting on behalf of any person or entity who
                                           could not truthfully make these statements.

Effect of not tendering..............  Any outstanding unregistered notes that are not tendered or
                                       that are tendered but not accepted will remain subject to
                                       the restrictions on transfer. Since the outstanding
                                       unregistered notes have not been registered under the
                                       Securities Act, they bear a legend restricting their
                                       transfer absent registration or the availability of a
                                       specific exemption from registration. Upon the completion of
                                       the exchange offer, we will have no further obligations,
                                       except under limited circumstances, to provide for
                                       registration of the outstanding unregistered notes under the
                                       Securities Act.

Interest on the exchange notes and
  the outstanding unregistered
  notes..............................  The exchange notes will bear interest from the most recent
                                       interest payment date to which interest has been paid on the
                                       tendered outstanding unregistered notes or, if no interest
                                       has been paid, from April 25, 2003. Interest on the
                                       outstanding unregistered notes accepted for exchange will
                                       cease to accrue upon the issuance of the exchange notes.

Withdrawal rights....................  Tenders of outstanding unregistered notes may be withdrawn
                                       at any time prior to 5:00 p.m., New York City time, on the
                                       expiration date.

Federal tax consequences.............  There will be no federal income tax consequences to you if
                                       you exchange your outstanding unregistered notes for
                                       exchange notes in the exchange offer.

Regulatory Approvals.................  Other than the federal securities laws, there are no federal
                                       or state regulatory requirements that we must comply with
                                       and there are no approvals that we must obtain in connection
                                       with the exchange offer.

Exchange agent.......................  The Bank of New York, the trustee under the indenture, is
                                       serving as exchange agent in connection with the exchange
                                       offer.

                                       plus accrued and unpaid interest and liquidated damages
                                       thereon, if any, to the date of redemption.

Sinking fund.........................  None.

Change of control....................  Upon the occurrence of a change of control, you will have
                                       the right to require us to repurchase all or a portion of
                                       your exchange notes at a purchase price in cash equal to
                                       101% of the principal amount thereof, plus accrued and
                                       unpaid interest and liquidated damages thereon, if any, to
                                       the date of repurchase.

Note guarantee.......................  The exchange notes will be irrevocably fully and
                                       unconditionally guaranteed (the 'note guarantee') on an
                                       unsecured senior basis by Millennium Chemicals. The exchange
                                       notes will not be guaranteed by any of Millennium Chemicals'
                                       subsidiaries. As of March 31, 2003, these subsidiaries
                                       (other than Millennium America) had approximately $240
                                       million of trade payables and $24 million of total
                                       indebtedness outstanding (exclusive of unused commitments
                                       and $9 million of undrawn outstanding standby letters of
                                       credit) and held approximately 99% of Millennium Chemicals'
                                       consolidated assets. For the three months ended March 31,
                                       2003 and the year ended December 31, 2002, these
                                       subsidiaries generated approximately 100% of Millennium
                                       Chemicals' consolidated net sales.

Security and ranking.................  The exchange notes:

                                        will be general unsecured, senior obligations of Millennium
                                        America;

                                        will rank equally in right of payment with all existing and
                                        future senior indebtedness of Millennium America;

                                        will be senior in right of payment to all future
                                        subordinated obligations of Millennium America;

                                        will be effectively subordinated to any secured indebtedness
                                        of Millennium America and its subsidiaries

                                        to the extent of the value of the assets securing such
                                        indebtedness; and

                                        will be effectively subordinated to all liabilities
                                        (including trade payables) and preferred stock of each
                                        subsidiary of Millennium America.

                                       The note guarantee of Millennium Chemicals:

                                        will be a general unsecured, senior obligation of Millennium
                                        Chemicals;

                                        will rank equally in right of payment with all existing and
                                        future senior indebtedness of Millennium Chemicals;

                                        will be senior in right of payment to all future
                                        subordinated obligations of Millennium Chemicals;

                                        will be effectively subordinated to any secured indebtedness
                                        of Millennium Chemicals and its subsidiaries to the extent
                                        of the value of the assets securing such indebtedness; and

                                        will be effectively subordinated to all liabilities
                                        (including trade payables) and preferred stock of each
                                        subsidiary of Millennium Chemicals (other than Millennium
                                        America).

                                       As of March 31, 2003, on a pro forma basis to give effect to
                                       the issuance of the outstanding unregistered notes on
                                       April 25, 2003, and the use of proceeds thereof as
                                       described in 'The Offering':

                                        Millennium America, excluding its consolidated subsidiaries,
                                        would have had approximately $1,297 million of senior
                                        indebtedness (including the outstanding unregistered
                                        notes), of which $48 million would have been secured
                                        indebtedness under the bank credit agreement (exclusive of
                                        unused commitments under the bank credit agreement, and
                                        $12 million of undrawn outstanding standby letters of
                                        credit);

                                        Millennium Chemicals, excluding its consolidated
                                        subsidiaries, would have had approximately $1,249 million
                                        of senior indebtedness, consisting of the note guarantee
                                        and its guarantee of Millennium America's other notes and
                                        debentures, none of which would have been secured
                                        indebtedness (in each case, exclusive of guarantees of
                                        indebtedness under the bank credit agreement and $1 million
                                        of undrawn outstanding standby letters of credit);

                                        Millennium Chemicals and Millennium America would have had
                                        no subordinated obligations; and

                                        the subsidiaries of Millennium Chemicals (other than
                                        Millennium America) would have had $240 million of trade
                                        payables and $24 million of total indebtedness outstanding
                                        (exclusive of unused commitments and $9 million of undrawn
                                        outstanding standby letters of credit). In addition, since
                                        each of Millennium Chemicals and Millennium America
                                        conducts all of its operations through its subsidiaries,
                                        the subsidiaries of Millennium Chemicals (other than
                                        Millennium America) have substantial operating liabilities.

Certain covenants..................... The indenture, among other things, restricts Millennium
                                       Chemicals', Millennium America's and the other restricted
                                       subsidiaries' ability to:

                                         incur additional debt;

                                         issue redeemable stock and preferred stock;

                                         pay dividends or make distributions;

                                         repurchase capital stock;

                                         make other restricted payments including, without
                                         limitation, investments;

                                         create liens;

                                         redeem debt that is junior in right of payment to the notes;

                                         sell or otherwise dispose of assets, including capital stock
                                         of subsidiaries;

                                         enter into arrangements that restrict dividends from
                                         subsidiaries;

                                         enter into mergers or consolidations;

                                         enter into transactions with affiliates; and

                                         enter into sale/leaseback transactions.

                                       These covenants will be subject to a number of important
                                       exceptions and qualifications. In addition, if we achieve
                                       certain debt ratings from Standard & Poor's and Moody's
                                       Investors Service and meet certain other requirements,
                                       certain of these covenants will no longer apply.

No assurance of liquid market for the
  exchange notes.....................  Although the exchange notes will trade with the currently
                                       outstanding registered 9 1/4% Senior Notes due 2008, there
                                       can be no assurance as to the liquidity of any market for
                                       those notes. The initial purchasers of the outstanding
                                       unregistered notes currently make a market in the
                                       outstanding registered notes. However, they are not
                                       obligated to do so, and may discontinue any market making
                                       with respect to those notes at any time without notice. We
                                       do not intend to apply for listing of the exchange notes on
                                       any securities exchange or to arrange for any quotation
                                       system to quote them.

Tax consequences.....................  The ownership and disposition of the exchange notes have
                                       certain U.S. Federal tax consequences. For more details, see
                                       'Certain Income Tax Considerations.'

Accounting Treatment.................  The exchange notes will be recorded at the same carrying
                                       value as the outstanding unregistered notes. The carrying
                                       value is the aggregate gross proceeds received from the sale
                                       of the unregistered notes as reflected in our accounting
                                       records on the date of exchange. Accordingly, we will
                                       recognize no gain or loss for accounting purposes. The
                                       expenses of the exchange offer will be expensed over the
                                       term of the exchange notes.

                                           RISK FACTORS

    You should consider carefully all of the information contained in or incorporated by reference
into this prospectus and, in particular, should evaluate the specific factors under 'Risk Factors'
beginning on page 11 before determining whether to participate in the exchange offer.


                                       10









                                  RISK FACTORS

    You should carefully consider the following factors, together with the other
information included or incorporated by reference in this prospectus, before
determining whether to participate in the exchange offer. These factors, other
than the first factor, are generally applicable to the outstanding unregistered
notes as well as the exchange notes.

RISKS RELATING TO THE EXCHANGE NOTES

IF YOU FAIL TO EXCHANGE YOUR OUTSTANDING UNREGISTERED NOTES FOR EXCHANGE NOTES
IN THE EXCHANGE OFFER, YOUR OUTSTANDING UNREGISTERED NOTES WILL CONTINUE TO BE
SUBJECT TO TRANSFER RESTRICTIONS AND MAY HAVE REDUCED LIQUIDITY.

    In the event the exchange offer is completed, holders of outstanding
unregistered notes which have not been exchanged who seek liquidity in their
investment would have to rely on exemptions to the registration requirements
under the securities laws, including the Securities Act, since the outstanding
unregistered notes will continue to be subject to restrictions on transfer.
Consequently, holders of outstanding unregistered notes who do not participate
in the exchange offer could experience significant diminution in the value of
their outstanding unregistered notes, compared to the value of the exchange
notes. Following the exchange offer, none of the exchange notes will be entitled
to the contingent liquidated damages provided for in the event of a failure to
complete the exchange offer in accordance with the terms of the registration
rights agreement. In addition, we do not intend to register resales of the
outstanding unregistered notes under the Securities Act, except as required by
the registration rights agreement.

OUR SUBSTANTIAL INDEBTEDNESS CAUSES US TO HAVE SIGNIFICANT DEBT SERVICE
OBLIGATIONS, WHICH REDUCES OUR CASH FLOW AVAILABLE TO FUND OPERATIONS.

    Millennium Chemicals and its consolidated subsidiaries have substantial
indebtedness and, as a result, significant debt service obligations. As of
March 31, 2003, their total indebtedness outstanding aggregated approximately
$1,257 million (excluding unused commitments and $22 million of outstanding
undrawn standby letters of credit), representing approximately 76% of their
total capitalization. For the three months ended March 31, 2003, on a pro forma
basis to give effect for the entire period to the issuance of $100 million
aggregate principal amount of the outstanding unregistered notes in April 2003
and the use of the gross proceeds thereof to repay $85 million of outstanding
indebtedness under the revolving credit facility under our bank credit
agreement, Millennium Chemicals' and its consolidated subsidiaries' interest
expense would have been $24 million and the ratio of earnings to fixed charges
would have been 1.2x. In addition, Millennium Chemicals' debt instruments permit
Millennium Chemicals and its consolidated subsidiaries to incur or guarantee
certain additional indebtedness, subject to certain limitations. Our debt
service obligations reduce our cash flow available to fund our operations and
future business requirements.

OUR SUBSTANTIAL INDEBTEDNESS COULD ADVERSELY AFFECT OUR ABILITY TO OPERATE OUR
BUSINESS AND LIMIT OUR ABILITY TO OBTAIN ADDITIONAL FINANCING.

    The degree of our leverage could have significant consequences to holders of
exchange notes, including:

         limiting our ability to obtain additional financing on satisfactory
         terms to fund our business operations;

         increasing our vulnerability to general economic downturns and adverse
         competitive and industry conditions, which could place us at a
         competitive disadvantage;

         increasing our exposure to interest rate increases because a portion of
         our borrowings are at variable interest rates;

                                       11






         reducing the availability of our cash flow to fund our business
         operations because we will be required to use a substantial portion of
         our cash flow to service our debt obligations; and

         limiting our flexibility in planning for, or reacting to, changes in
         our business and the chemical industry.

SERVICING OUR DEBT OBLIGATIONS REQUIRES A SIGNIFICANT AMOUNT OF CASH, AND OUR
ABILITY TO GENERATE CASH DEPENDS ON MANY FACTORS BEYOND OUR CONTROL.

    Our ability to satisfy our debt service obligations will depend, among other
things, upon our future operating performance, the future operating performance
of Equistar and our ability to refinance indebtedness when necessary. Each of
these factors is to a large extent dependent on economic, financial, competitive
and other factors beyond our control. The amount of cash distributions we
receive from Equistar will be affected by its results of operations and cash
flow and by the agreements under which it operates. We did not receive any cash
distributions from Equistar during 2001 or 2002, and it is unlikely that we will
receive any distributions during 2003. If, in the future, we cannot generate
sufficient cash from our operations and from Equistar to meet our debt service
obligations, we may need to reduce or delay capital expenditures or curtail
research and development efforts. In addition, we may need to refinance our
debt, obtain additional financing or sell assets, which we may not be able to do
on commercially reasonable terms, if at all. We cannot assure you that our
business or that of Equistar will generate sufficient cash flow, or that we will
be able to obtain funding, sufficient to satisfy our debt service obligations.

RESTRICTIONS IMPOSED BY OUR DEBT INSTRUMENTS MAY LIMIT OUR ABILITY TO FINANCE
FUTURE OPERATIONS OR CAPITAL NEEDS OR ENGAGE IN OTHER BUSINESS ACTIVITIES THAT
MAY BE IN OUR INTEREST. OUR FAILURE TO COMPLY WITH THESE RESTRICTIONS COULD LEAD
TO AN ACCELERATION OF OUR INDEBTEDNESS.

    Our debt instruments contain numerous financial and operating covenants
that, among other things, limit Millennium Chemicals' and its subsidiaries'
ability to (1) incur additional indebtedness, (2) repurchase or redeem capital
stock, (3) create liens or other encumbrances, (4) redeem debt that is junior in
right of payment to the notes, (5) make certain payments and investments,
including dividend payments, (6) enter into sale/leaseback transactions,
(7) sell or otherwise dispose of assets, (8) merge or consolidate with other
entities or (9) engage in certain transactions with subsidiaries and affiliates
and otherwise restrict corporate activities. Our bank credit agreement also
requires us to meet certain financial ratios and tests. Agreements governing
future indebtedness could also contain significant financial and operating
restrictions. Our ability to comply with these restrictions may be affected by
factors beyond our control. A failure to comply with the obligations contained
in our bank credit agreement or our indentures could result in an event of
default under our bank credit agreement or the indentures, which could permit
acceleration of the related debt and acceleration of debt under other
instruments that may contain cross-acceleration or cross-default provisions. We
are not certain whether we would have, or be able to obtain, sufficient funds to
make these accelerated payments. In that event, the lenders under our bank
credit agreement could proceed against our assets that secure their debt.

MILLENNIUM AMERICA AND MILLENNIUM CHEMICALS ARE HOLDING COMPANIES AND DEPEND ON
THE RECEIPT OF DIVIDENDS OR OTHER PAYMENTS FROM THEIR SUBSIDIARIES TO PAY THE
PRINCIPAL OF AND INTEREST ON THE NOTES.

    Each of Millennium America and Millennium Chemicals is a holding company,
the primary asset of which is 100% of the outstanding capital stock of an
intermediate holding company, which, in turn, is the direct or indirect parent
of numerous subsidiaries. Millennium Chemicals will unconditionally guarantee
the exchange notes on a senior unsecured basis. Each of Millennium America, in
repaying its indebtedness with respect to the exchange notes, and Millennium

                                       12






Chemicals, in satisfying its obligations under its guarantee of the exchange
notes, must rely on cash flows from its respective subsidiaries, including
dividends or other payments. Millennium America has no ownership interest in a
number of subsidiaries of Millennium Chemicals, including those that own the
United Kingdom, French, Australian and Brazilian TiO[u]2 operations.

    The ability of Millennium America's and Millennium Chemicals' subsidiaries
to make payments to Millennium America and Millennium Chemicals, respectively,
is subject to, among other things, applicable corporate laws and other laws and
regulations of the applicable state or foreign jurisdiction. State corporate law
applicable to Millennium America's principal subsidiaries generally prohibits
the payment of dividends by any subsidiary unless the subsidiary has capital
surplus or net profits in the current or immediately preceding year.

    Although the indenture under which the exchange notes will be issued limits
the ability of our subsidiaries to enter into consensual restrictions on their
ability to pay dividends and make other payments, these limitations have a
number of significant qualifications and exceptions. See 'Description of
Exchange Notes -- Certain Covenants -- Limitation on Restrictions on
Distributions from Restricted Subsidiaries.'

CLAIMS OF CREDITORS OF SUBSIDIARIES OF MILLENNIUM CHEMICALS AND MILLENNIUM
AMERICA AS WELL AS CREDITORS OF EQUISTAR MAY HAVE PRIORITY OVER CLAIMS OF
NOTEHOLDERS WITH RESPECT TO THE ASSETS AND EARNINGS OF THESE COMPANIES.

    The holders of the exchange notes will have no direct claims against
Millennium America's subsidiaries or Millennium Chemicals' subsidiaries (other
than Millennium America). Generally, creditors of subsidiaries of Millennium
America and Millennium Chemicals will have claims to the assets and earnings of
these subsidiaries that are superior to claims of creditors of Millennium
America and Millennium Chemicals, respectively. Therefore, claims of holders of
the indebtedness of Millennium America and Millennium Chemicals, including, with
respect to Millennium America, the exchange notes and, with respect to
Millennium Chemicals, the guarantee of the exchange notes, against the cash flow
and assets of subsidiaries of Millennium America and Millennium Chemicals,
respectively, will be effectively subordinated to claims of these subsidiaries'
creditors. As of March 31, 2003, subsidiaries of Millennium America had
approximately $111 million of trade payables and no indebtedness outstanding
(excluding unused commitments and $3 million of outstanding undrawn standby
letters of credit) and subsidiaries of Millennium Chemicals (other than
Millennium America) had approximately $240 million of trade payables and $24
million of total indebtedness outstanding (excluding unused commitments and
$9 million of outstanding undrawn standby letters of credit). Since Millennium
America and Millennium Chemicals conduct all of their operations through their
subsidiaries, their subsidiaries (other than, with respect to Millennium
Chemicals, Millennium America) also have substantial operating liabilities. In
the event of Millennium America's or Millennium Chemicals' dissolution,
bankruptcy, liquidation or reorganization, the holders of the exchange notes may
not receive any amounts with respect to the exchange notes until after payment
in full of the claims of creditors of subsidiaries of Millennium America and
Millennium Chemicals.

    Claims of holders of the exchange notes against the cash flow and assets of
Equistar and its subsidiaries will be effectively subordinated to claims of
creditors of Equistar and its subsidiaries. As of March 31, 2003, Equistar and
its subsidiaries had $480 million of accounts payable and $2.2 billion of
long-term indebtedness outstanding.

THE EXCHANGE NOTES WILL NOT BE SECURED BY ANY OF OUR ASSETS. HOWEVER, OUR BANK
CREDIT AGREEMENT IS SECURED AND, THEREFORE, OUR BANK LENDERS WILL HAVE A PRIOR
CLAIM ON CERTAIN OF OUR ASSETS.

    The exchange notes will not be secured by any of our assets. However, our
bank credit agreement is secured by (1) a pledge of 100% of the stock of
Millennium Chemicals' existing and future domestic subsidiaries, including
Millennium America, and 65% of the stock of Millennium Chemicals' existing and
future first-tier foreign subsidiaries, in both cases other than subsidiaries

                                       13






that hold immaterial assets, (2) all the equity interests held by Millennium
Chemicals' subsidiaries in Equistar and La Porte Methanol Company (which pledge
is limited to the right to receive distributions made by Equistar and La Porte
Methanol Company, respectively), and (3) all present and future accounts
receivable, intercompany indebtedness and inventory of Millennium America and
its domestic subsidiaries other than subsidiaries that hold immaterial assets.
If Millennium Chemicals becomes insolvent or is liquidated, or if payment under
any of the instruments governing its secured debt is accelerated, the lenders
under these instruments will be entitled to exercise the remedies available to a
secured lender under applicable law and pursuant to instruments governing such
debt. Accordingly, the lenders will have a prior claim on Millennium Chemicals'
assets. In that event, because the exchange notes will not be secured by any of
Millennium Chemicals' assets, it is possible that Millennium Chemicals'
remaining assets might be insufficient to satisfy your claims in full.

WE COULD ENTER INTO VARIOUS TRANSACTIONS, SUCH AS ACQUISITIONS, REFINANCINGS,
RECAPITALIZATIONS OR OTHER HIGHLY LEVERAGED TRANSACTIONS, THAT WOULD NOT
CONSTITUTE A CHANGE OF CONTROL, BUT WOULD NEVERTHELESS INCREASE THE AMOUNT OF
OUR OUTSTANDING DEBT, OR ADVERSELY AFFECT OUR CAPITAL STRUCTURE OR CREDIT
RATINGS, OR OTHERWISE ADVERSELY AFFECT HOLDERS OF THE EXCHANGE NOTES.

    Under the terms of the notes, a variety of acquisition, refinancing,
recapitalization or other highly leveraged transactions are not considered
change of control transactions. As a result, we could enter into any such
transaction without being required to make an offer to repurchase the notes even
though the transaction could increase the total amount of our outstanding
indebtedness, adversely affect our capital structure or credit ratings or
otherwise adversely affect the holders of the exchange notes.

WE MAY NOT HAVE THE ABILITY TO RAISE THE FUNDS TO PURCHASE THE EXCHANGE NOTES
UPON A CHANGE OF CONTROL AS REQUIRED BY THE INDENTURE.

    Upon the occurrence of certain change of control events, each holder of
exchange notes may require us to repurchase all or a portion of its exchange
notes at a purchase price equal to 101% of the principal amount thereof, plus
accrued interest and liquidated damages. Our ability to repurchase the exchange
notes upon a change of control will be limited by the terms of our other debt
agreements. Upon a change of control, we may be required immediately to repay
the outstanding principal, any accrued interest and any other amounts owed by us
under our bank credit agreement. We cannot assure you that we would be able to
repay amounts outstanding under our bank credit agreement or obtain necessary
consents under such agreement to repurchase the exchange notes. Any requirement
to offer to purchase any exchange notes may result in our having to refinance
our outstanding indebtedness, which we may not be able to do. In addition, even
if we were able to refinance such indebtedness, such financing may not be on
terms favorable to us.

IN THE EVENT OF A SALE OF ALL OR SUBSTANTIALLY ALL OF OUR ASSETS, THERE MAY BE A
DEGREE OF UNCERTAINTY AS TO WHETHER A CHANGE OF CONTROL HAS OCCURRED WHICH WILL
GIVE RISE TO OUR REPURCHASE OBLIGATIONS UNDER THE INDENTURE.

    One of the events that would trigger a change of control is a sale of 'all
or substantially all' of our assets. Although there is a limited body of case
law interpreting the phrase 'all or substantially all' as used in the definition
of 'change of control' set forth in the indenture governing the notes, there is
no precise established definition of the phrase under New York law (which is the
governing law of the indenture). As a consequence, there may be a degree of
uncertainty as to whether a change of control has occurred giving rise to the
repurchase obligations under the indenture. It is possible, therefore, that
there could be a disagreement between us and some or all holders of the notes
over whether one or more specific asset sales would trigger a change of control
offer. In addition, if the holders of the notes elected to exercise their rights
under the indenture to require us to repurchase all or a portion of their notes
and we

                                       14






elected to contest that election, there can be no assurance as to how a court
interpreting New York law would interpret the phrase 'all or substantially all.'

WE CANNOT GUARANTEE THAT AN ACTIVE TRADING MARKET WILL DEVELOP FOR THE EXCHANGE
NOTES OR THAT YOU WILL BE ABLE TO SELL YOUR EXCHANGE NOTES.

    Although the exchange notes will trade with the currently outstanding
registered 9 1/4 Senior Notes due 2008, there can be no assurance as to the
liquidity of any market for those notes. The liquidity of any market for the
notes will depend on the number of holders of the notes, our performance, the
market for similar securities, the interest of securities dealers in making a
market in the notes and other factors. Each initial purchaser of the outstanding
unregistered notes currently makes a market in the outstanding registered notes.
However, the initial purchasers are not obligated to do so, and any market
making by the initial purchasers may be discontinued at any time without notice.
We do not intend to apply for listing of the exchange notes on any securities
exchange or for quotation through the National Association of Securities Dealers
Automated Quotation System.

UNDER U.S. FEDERAL AND STATE FRAUDULENT TRANSFER OR CONVEYANCE STATUTES, A COURT
COULD VOID THE OBLIGATIONS OF MILLENNIUM AMERICA AND MILLENNIUM CHEMICALS OR
TAKE OTHER ACTIONS DETRIMENTAL TO HOLDERS OF THE EXCHANGE NOTES OFFERED HEREBY.

    Under U.S. federal or state fraudulent transfer or conveyance laws, a court
could take actions detrimental to you if it found that, at the time the exchange
notes offered hereby or the exchange note guarantee were issued:

        (1) Millennium America or Millennium Chemicals issued the exchange notes
    or the exchange note guarantee with the intent of hindering, delaying or
    defrauding current or future creditors; or

        (2) (a) Millennium America or Millennium Chemicals received less than
    fair consideration for incurring the debt represented by the exchange notes
    or the exchange note guarantee; and

            (b) Millennium America or Millennium Chemicals:

                was insolvent or rendered insolvent by issuing the exchange
                notes or the exchange note guarantee;

                was engaged in a business or transaction for which the assets
                remaining with Millennium America or Millennium Chemicals would
                constitute unreasonably small capital; or

                incurred debt beyond Millennium America's or Millennium
                Chemicals' ability to pay.

If a court made such a finding, it could:

            void all or part of Millennium America's or Millennium Chemicals'
            obligations to the holders of the exchange notes and direct the
            repayment of any amounts thereunder to Millennium America's or
            Millennium Chemicals' other creditors;

            subordinate Millennium America's or Millennium Chemicals'
            obligations to the holders of the exchange notes to Millennium
            America's or Millennium Chemicals' other debt; or

            take other actions detrimental to the holders of the exchange notes.

If this were to occur, we cannot assure you that Millennium America could pay
amounts due on the exchange notes offered hereby.

    We cannot predict what standard a court would apply to determine whether
either Millennium America or Millennium Chemicals was insolvent as of the date
Millennium America or Millennium Chemicals issued the exchange notes or the
exchange note guarantee, or that regardless of the method of valuation, a court
would determine that Millennium America or Millennium Chemicals

                                       15






was insolvent on that date, or whether a court would determine that the payments
constituted fraudulent transfers or conveyances on other grounds.

    To the extent a court voids the exchange note guarantee as a fraudulent
transfer or conveyance or holds it unenforceable for any other reason, holders
of exchange notes offered hereby would cease to have any claim against
Millennium Chemicals. If a court were to take this action, we cannot assure you
that Millennium America's assets would be sufficient to satisfy the claims of
the holders of exchange notes relating to any voided portions of the exchange
note guarantee.

RISKS RELATING TO OUR BUSINESS

THE CYCLICALITY AND VOLATILITY OF THE CHEMICAL INDUSTRY MAY ADVERSELY AFFECT OUR
INCOME AND CASH FLOW LEVELS, AND MAY CAUSE FLUCTUATIONS IN OUR RESULTS OF
OPERATIONS.

    Our income and cash flow levels reflect the cyclical nature of the chemical
industries in which we operate. Certain of these industries are mature and
sensitive to cyclical supply and demand balances. In particular, the markets for
ethylene and polyethylene, in which we participate through our interest in
Equistar, are highly cyclical, resulting in volatile profits and cash flow over
the business cycle. Further, the global markets for TiO[u]2, VAM, acetic acid
and our fragrance and flavor chemicals are cyclical, although to a lesser
degree. The balance of supply and demand in the markets in which we and Equistar
do business, as well as the level of inventories held by downstream customers,
has a direct effect on the sales volumes and prices of our products as well as
Equistar's. For example, if supply exceeds demand, producers are often pressured
to maintain sales volumes with customers and, consequently, pressure to reduce
prices may result. This is especially true in periods of economic decline or
uncertainty, when demand may be limited and the economic conditions create
caution on the part of customers to build inventory. Reaction by producers,
including us and Equistar, is dependent on the particular circumstances in
effect at the time, but could include meeting competitive price reductions,
short-term curtailment of production, and longer-term temporary or permanent
plant shutdowns.

    Demand for TiO[u]2 is influenced by changes in the gross domestic product of
various regions of the world and has fluctuated from year to year. The industry
is also sensitive to changes in its customers' marketplaces, which are primarily
the paint and coatings, plastics and paper industries. In recent history,
consolidations and negative business conditions within certain of those
industries have put pressure on TiO[u]2 prices as companies compete to keep
volumes placed.

    Demand for ethylene, its derivatives and acetyls has fluctuated from year to
year. These industry segments are particularly sensitive to capacity additions.
Producers have historically experienced alternating periods of inadequate
capacity, resulting in increased selling prices and operating margins, followed
by periods of large capacity additions, resulting in declining capacity
utilization rates, selling prices and operating margins. Profitability is
further influenced by fluctuations in the price of feedstocks for ethylene,
which generally follow price trends for crude oil or natural gas.

    Currently, there is overcapacity in the petrochemical and polymer
industries, as a number of Equistar's competitors in various segments of the
petrochemical and polymer industries have added capacity. There can be no
assurance that future growth in product demand will be sufficient to utilize
current or any additional capacity. Excess petrochemical and polymer industry
capacity has depressed, and may continue to depress, Equistar's volumes and
margins. For example, in 2002, U.S. ethylene demand was estimated to be 2.8%
higher than for 2001. Nonetheless, the 2002 demand growth was insufficient to
absorb excess worldwide ethylene industry capacity and to fully offset the
effects of a contraction in U.S. ethylene demand in 2001 compared to 2000. The
global economic and political environment continues to be uncertain,
contributing to low petrochemical and polymer industry operating rates, adding
to the volatility of raw material and energy costs, and forestalling the
industry's recovery from trough conditions, all of which is placing, and may
continue to place, pressure on Equistar's results of operations. As a result of
excess petrochemical and polymer industry capacity and weak demand for products,
as

                                       16






well as rising energy costs and raw material prices, Equistar's operating income
has declined and may remain volatile.

    Different facilities may have differing operating rates from
period-to-period depending on supply and demand for the product produced at the
facility during that period, which may be affected by many factors, such as
energy costs, feedstock costs and transportation costs. As a result, individual
facilities may be operated below or above rated capacities, may be idled or may
be shut down and restarted in any period. It is possible that lower demand in
the future will cause us to reduce operating rates.

OUR BUSINESS AND EQUISTAR'S BUSINESS ARE SUBJECT TO MATERIAL FLUCTUATIONS DUE TO
EXTERNAL FACTORS WHICH MAY NEGATIVELY AFFECT OUR AND EQUISTAR'S FINANCIAL
CONDITION AND RESULTS OF OPERATIONS.

    External factors beyond our control, such as general economic conditions,
weather, competitor actions, international events and governmental regulation in
the United States and abroad, can cause fluctuations in demand for our products,
fluctuations in prices and margins and volatility in the price of raw materials
that we purchase. In particular, demand within the primary end-markets for our
and Equistar's products is generally a function of regional economic conditions
in geographic areas in which sales are generated. In addition, our business
depends on the free flow of products and services through the channels of
commerce. In response to terrorists' activities and threats aimed at the United
States, transportation, mail, financial and other services have been slowed.
Further delays or stoppages in transportation, mail, financial and other
services could have a material adverse effect on our business, results of
operations and financial condition. Furthermore, we may experience an increase
in operating costs, such as costs for transportation, insurance and security as
a result of these activities and threats. To the extent the U.S. economy is
adversely affected by terrorist activities and potential activities and events
in the Middle East, any economic downturn could adversely impact our results of
operations, impair our ability to raise capital or otherwise adversely affect
our business. These external factors can magnify the impact of industry cycles.
For example, first quarter 2003 TiO[u]2 sales volume was lower than first
quarter 2002 sales volume, partially due to uncertain economic conditions and
generally poorer weather that held back demand and delayed the traditional March
start of the North American and European coatings season. As a result, our
income and cash flow are subject to material fluctuations. The cash
distributions we expect to receive from Equistar may be affected by the same or
similar external factors.

OUR PARTICIPATION IN THE EQUISTAR JOINT VENTURE EXPOSES US TO RISKS OF SHARED
CONTROL AND FUTURE CAPITAL COMMITMENTS WHICH, AMONG OTHER THINGS, MAY ADVERSELY
AFFECT EQUISTAR'S BUSINESS OR OUR RESULTS OF OPERATIONS.

    We rely, in part, on cash distributions from Equistar. We did not receive
any cash distributions from Equistar during 2001 or 2002, and it is unlikely
that we will receive any distributions during 2003. Our cash flow could be
adversely affected by actions taken by Equistar or Lyondell, our partner in
Equistar, or by conditions that affect Equistar or its business. In particular,
if Lyondell does not fulfill its obligations under the Equistar partnership
agreement, Equistar may not be able to operate according to its business plan.
If this were to occur, our results of operations could be adversely affected. In
addition, although unanimous consent of both us and Lyondell is required for
aggregate partner contributions not contemplated by an approved strategic plan
that exceed $100 million in any given year or $300 million in a five-year
period, we may be required, without our consent, to contribute amounts up to our
pro rata portion of such amounts or an unlimited amount to allow Equistar to
achieve or maintain compliance with certain health, safety and environmental
laws. If we fail to contribute these amounts, we may have to sell our interest
in Equistar to Lyondell at a price or on terms which may be unfavorable to us.

                                       17






RISING COSTS OF ENERGY AND OTHER RAW MATERIALS MAY RESULT IN INCREASED OPERATING
EXPENSES AND REDUCED RESULTS OF OPERATIONS.

    We and Equistar purchase large amounts of raw materials for our respective
businesses. The cost of these materials, in the aggregate, represents a
substantial portion of our operating expenses. The prices and availability of
these raw materials vary with market conditions and may be highly volatile. In
addition, we and Equistar use large amounts of energy in our respective
operations. The benchmark prices of crude oil and natural gas increased
significantly during the second half of 2002 and the first quarter of 2003. As
these costs rise, operating expenses increase and could have a particularly
negative impact on Equistar and our Acetyls business segment. From time to time,
we and Equistar may enter into transactions to manage the volatility of such
costs, but we cannot assure you that these actions will have a favorable impact
on our results of operations nor can we assure you that we will continue to
enter into such transactions in the future. Energy costs remain volatile.

    There have been in the past, and will likely be in the future, periods of
time when we are unable to pass raw material price increases on to our customers
in whole or in part. Customer consolidation in our TiO[u]2 business has made it
more difficult to pass costs along to customers, so that increased raw material
prices may negatively affect our operating margins.

    In our Titanium Dioxide and Related Products business segment,
titanium-bearing ores are our primary raw materials, but we also purchase large
quantities of chlorine, sulfuric acid, caustic soda, petroleum products and
metallurgical coke, aluminum, sodium silicate, oxygen and nitrogen. In our
Acetyls business segment, our primary raw materials are natural gas, carbon
monoxide, methanol and ethylene, and in our Specialty Chemicals business
segment, our primary raw materials are crude sulfate turpentine, or CST, and gum
turpentine or their derivatives. In addition, Equistar purchases petroleum
liquids, including naptha, condensates and gas oils and natural gas liquids,
including ethane, propane and butane.

    We use natural gas as a feedstock and as a source of energy. Fluctuations in
the price of natural gas affect our operating expenses which, in turn, affect
our results of operations. During the fourth quarter of 2002 and first quarter
of 2003, our results of operations were affected by the rising costs of natural
gas. Our Acetyls business segment has the largest exposure to natural gas costs
of our majority-owned businesses. Our Titanium Dioxide and Related Products and
Specialty Chemicals business segments are impacted to a lesser extent.

    The costs of raw materials and energy used in Equistar's business represent
a substantial portion of Equistar's operating expenses. These costs generally
follow the prices for natural gas and crude oil. Due to the commodity nature of
most of Equistar's products, Equistar is generally not able to protect its
market position by product differentiation and may not be able to pass on all
cost increases to its customers. Accordingly, increases in raw material and
other costs may not necessarily correlate with changes in product prices, either
in the direction of the price change or in magnitude. In addition, higher
natural gas prices could adversely affect the international competitiveness of
many U.S. chemical producers. As a result, changes in the prices of commodities
and raw materials and other costs will affect Equistar's income and cash flow
which will, in turn, affect our financial condition and results of operations.

WE HAVE A LIMITED NUMBER OF SUPPLIERS FOR SOME OF OUR RAW MATERIALS, AND IF ONE
OF THESE SUPPLIERS WERE UNABLE TO MEET ITS OBLIGATIONS, WE COULD INCUR SUPPLY
SHORTAGES OR PRICE INCREASES FOR OUR RAW MATERIALS.

    Millennium Chemicals has a limited number of suppliers for some of its raw
materials, and the number of sources for and availability of raw materials is
specific to the particular geographic region in which a facility is located. In
2002, Millennium Chemicals and its consolidated subsidiaries purchased 76% of
their titanium-bearing ores from two suppliers, Rio Tinto Iron & Titanium Inc.
(through its affiliates Richards Bay Iron & Titanium (Proprietary) Limited and
QIT-Fer et Titane Inc.) and Iluka Resources Limited under multiple year
contractual commitments. In addition, they obtain chlorine and caustic soda
exclusively from one supplier for their Australian

                                       18






operations under a long-term supply agreement. For their other TiO[u]2
manufacturing plants, there are multiple suppliers for these raw materials and
they are generally purchased through short-term contracts. They also purchase
all of their ethylene requirements from Equistar under a supply contract based
on market prices. In addition, they purchase all of their carbon monoxide from
Linde AG pursuant to a long-term contract based primarily on the cost of
production. Each of the chloride TiO[u]2 manufacturing plants has long-term
supply agreements for oxygen and nitrogen through either 'over the fence'
suppliers dedicated to the site or through a direct pipeline arrangement. Each
of these contracts is an exclusive supply contract.

    Accordingly, if one of these suppliers were unable to meet its obligations
under present supply arrangements, we could suffer reduced supplies or be forced
to incur increased prices for our raw materials.

    Equistar purchases the majority of its natural gas and petroleum liquids
requirements through contractual arrangements from a variety of third-party
domestic and foreign sources, as well as on the spot market from third-party
domestic and foreign sources.

OPERATING PROBLEMS IN OUR OR EQUISTAR'S BUSINESS MAY MATERIALLY ADVERSELY AFFECT
OUR PRODUCTIVITY AND PROFITABILITY.

    The occurrence of material operating problems at our or Equistar's
facilities, including, but not limited to, the events described below, may have
a material adverse effect on the productivity and profitability of a particular
manufacturing facility, or on our or Equistar's operations as a whole, during
and after the period of such operational difficulties. Our income is dependent
on the continued operation of our and Equistar's various production facilities
and the ability to complete construction projects on schedule. Our and
Equistar's manufacturing operations are subject to the usual hazards associated
with chemical manufacturing and the related storage and transportation of raw
materials, products and wastes, including pipeline leaks and ruptures,
explosions, fires, inclement weather and natural disasters, mechanical failure,
unscheduled downtime, labor difficulties, transportation interruptions and
environmental hazards, such as chemical spills, discharges or releases of toxic
or hazardous substances or gases, storage tank leaks and matters relating to
remedial activities. These hazards can cause personal injury and loss of life,
severe damage to or destruction of property and equipment and environmental
contamination and other environmental damage, and may result in suspension of
operations and the imposition of civil or criminal penalties. Furthermore, we
and Equistar are also subject to present and future claims with respect to
workplace exposure, workers' compensation and other matters.

BECAUSE MILLENNIUM CHEMICALS' OPERATIONS ARE CONDUCTED WORLDWIDE, THEY ARE
AFFECTED BY RISKS OF DOING BUSINESS ABROAD, INCLUDING CURRENCY RISK.

    Millennium Chemicals and its consolidated subsidiaries generate revenue from
export sales, or sales outside the United States by their domestic operations,
as well as from their operations conducted outside the United States. They sell
their products to more than 90 countries. Sales outside the United States by
their domestic operations amounted to approximately 14%, 13% and 11% of total
revenues in 2002, 2001 and 2000, respectively. Revenue from non-United States
operations amounted to approximately 45%, 41% and 40% of total revenues in 2002,
2001 and 2000 respectively, principally reflecting the operations of the
Titanium Dioxide and Related Products business segment in Europe, Brazil and
Australia. Identifiable assets of the non-United States operations represented
35% and 28%, of total identifiable assets at December 31, 2002 and December 31,
2001, principally reflecting the assets of these operations. In addition, they
obtain a portion of their principal raw materials from sources outside the
United States. Ores used in the production of TiO[u]2 are obtained from
suppliers in South Africa, Australia, Canada and the Ukraine, along with that
from Millennium Chemicals' own mining operations in Brazil, and a portion of
their requirements of CST and gum turpentine and its derivatives is obtained
from suppliers in South America, and in the past they have fulfilled a portion
of these requirements from Indonesia and other Asian countries as well as
Europe.

                                       19






    Millennium Chemicals' international operations 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 have
an adverse effect on their international operations in the future by reducing
the demand for their products, decreasing the prices at which they can sell
their products or otherwise having an adverse effect on their business,
financial condition or results of operations. We cannot assure you that they
will continue to be found to be operating in compliance with applicable customs,
currency exchange control regulations, transfer pricing regulations or any other
laws or regulations to which they may be subject.

    The functional currency of each of Millennium Chemicals' non-United States
operations (principally, the operations of its Titanium Dioxide and Related
Products business segment in the United Kingdom, France, Brazil and Australia)
is the local currency. Exchange rates between these currencies and U.S. dollars
in recent years have fluctuated significantly and may do so in the future. As a
result of translating the functional currency financial statements of all
foreign subsidiaries into United States dollars, consolidated shareholders'
equity increased approximately $27 million during 2002 and decreased
approximately $19 million in 2001. Future events, which may significantly
increase or decrease the risk of future movement in foreign currencies in which
they conduct their business, cannot be predicted.

    In addition, Millennium Chemicals and its consolidated subsidiaries generate
revenue from export sales and operations conducted outside the United States
that may be denominated in currencies other than the relevant functional
currency. Millennium Chemicals and its consolidated subsidiaries hedge certain
revenues and costs to minimize the impact of changes in the exchange rates of
those currencies compared to the respective functional currencies. They do not
use derivative financial instruments for trading or speculative purposes. Net
foreign currency transactions aggregated gains of $3 million in 2002 and losses
of $7 million in 2001 and $4 million in 2000. It is possible that fluctuations
in foreign exchange rates will have a negative effect on their results of
operations.

WE SELL OUR PRODUCTS IN MATURE AND HIGHLY COMPETITIVE INDUSTRIES AND FACE PRICE
PRESSURE IN THE MARKETS IN WHICH WE OPERATE.

    The global markets in which our chemical businesses and the businesses of
Equistar operate are highly competitive. Competition is based on a number of
factors, such as price, product quality and service. Some of our competitors may
be able to drive down prices for our products because they have costs that are
lower than ours. In addition, some of our competitors may have greater
financial, technological and other resources than ours, and may be better able
to withstand changes in market conditions. Our competitors may be able to
respond more quickly to new or emerging technologies and changes in customer
requirements than we can. Further, consolidation of our competitors or customers
in any of the industries in which we compete may have an adverse effect on us.
The occurrence of any of these events could adversely affect our financial
condition and results of operations.

WE AND EQUISTAR ARE SUBJECT TO EXTENSIVE ENVIRONMENTAL REGULATIONS AND
ENVIRONMENTAL LIABILITIES THAT COULD REQUIRE US TO EXPEND MATERIAL AMOUNTS IN
COMPLIANCE, REMEDIATION, LITIGATION AND SETTLEMENT COSTS OR JUDGMENTS.

    Both our operations and those of Equistar are subject to extensive
requirements concerning the protection of the environment, including those
governing discharges of pollutants in the air and water, the generation,
management and disposal of hazardous substances and wastes and other materials
and the remediation of contamination and contaminated sites. Those operations
include chemical manufacturing plants and the distribution of chemical products
and involve the handling and use of hazardous substances. We and Equistar could
incur material liabilities, including clean-up costs, fines and civil and
criminal sanctions and claims by third parties for

                                       20






property damage and personal injury, as a result of violations of or liabilities
under environmental laws with respect to our operations and those of Equistar.
In addition, potentially significant expenditures could be required in
connection with any investigation and remediation of threatened or actual
pollution, increases in production that trigger more significant requirements
under existing environmental laws or requirements under future environmental
laws.

    Equistar's principal executive offices and many of its plants are located in
and around Houston, Texas. The eight-county Houston/Galveston region has been
designated a severe non-attainment area for ozone by the United States
Environmental Protection Agency, or EPA. In December 2000, the Texas Commission
on Environmental Equality, or TCEQ, has submitted a plan to the EPA to
demonstrate compliance with the ozone standard by the year 2007. Compliance with
this plan will result in increased capital investment by Equistar, which could
be between $200 million and $260 million before the 2007 deadline, as well as
higher annual operating costs for Equistar and could potentially affect cash
distributions from Equistar to us. In addition, under the partnership agreement
relating to Equistar, Equistar can require unlimited capital contributions from
each partner on a pro rata basis for certain environmental compliance costs,
such as these. In December 2002, TCEQ proposed revisions to the above
requirements which require the approval of the EPA, but which would decrease
Equistar's capital costs for compliance with the plan to between $165 million
and $200 million. Those revisions, however, also include new requirements that
would result in additional costs, which are currently still being assessed by
Equistar. In addition, the timing and amount of these expenditures are subject
to regulatory and other uncertainties, as well as obtaining the necessary
permits and approvals. At this time, we cannot estimate the ultimate capital or
operating costs of implementing any final plan by the 2007 deadline.

    We and certain of our subsidiaries have been named as defendants,
potentially responsible parties, or both, in a number of cleanup proceedings
with respect to various sites, including offsite waste disposal sites and
facilities currently or formerly owned or oeprated by our current or former
subsidiaries or their predecessors. In the most significant of these
proceedings, one of our subsidiaries is named as one of four potentially
responsible parties at the Kalamazoo River Superfund Site in Michigan at which
the EPA is considering selection of a remedial alternative to address
polychlorinated biphenyls contamination of river sediments. In October 2000, the
Kalamazoo River Study Group (of which our subsidiary is a member) submitted to
the State of Michigan a Draft Remedial Investigation and Draft Feasibility
Study, which evaluated a number of remedial options and recommended a remedy
involving the stabilization of several miles of river bank and the long-term
monitoring of river sediments at a total cost of approximately $73 million.
Other possible remedial alternatives previously identified by the State of
Michigan range from no action at no further cost to the complete dredging of
contaminated river sediments at a total cost for all parties of approximately
$2.5 billion. Based on current information, including the levels of known
contaminants, we believe that the selection of the remedial alternative
involving complete dredging of river sediments is remote. Our liability at the
site will depend on many factors, including the ultimate remedy selected by the
EPA, which has assumed lead agency status from the State of Michigan, a
determination of final allocation, the number and financial viability of the
other members of the study group as well as other potential PRPs and the
remediation methods and technologies available.

    While we believe that our businesses and the businesses of Equistar
generally operate in compliance with applicable environmental requirements and
that we maintain adequate reserves with respect to our remediation obligations
and the environmental proceedings in which we, our subsidiaries or Equistar have
been named as defendants or potentially responsible parties, there can be no
assurance that actual costs and liabilities for environmental matters will not
exceed the forecasted amounts or that estimates made with respect to
indemnification obligations will be accurate. It is also possible that costs
will be incurred with respect to sites or indemnification obligations that
currently are unknown, or as to which it is currently not possible to make an
estimate.

PROCEEDINGS RELATING TO THE ALLEGED EXPOSURE TO LEAD-BASED PAINTS AND LEAD
PIGMENTS COULD REQUIRE US TO EXPEND MATERIAL AMOUNTS IN LITIGATION AND
SETTLEMENT COSTS AND JUDGMENTS.

    Together with other alleged past manufacturers of lead-based paint and lead
pigments for use in paint, we have been named as defendants in various legal
proceedings alleging that we and other manufacturers are responsible for
personal injury, property damage, and remediation costs allegedly associated
with the use of these products. The plaintiffs in these legal proceedings
include municipalities, counties, school districts, individuals and the State of
Rhode Island, and seek recovery under a variety of theories, including
negligence, failure to warn, breach of warranty, conspiracy, market share
liability, fraud, misrepresentation and nuisance. Most of these legal
proceedings. In addition, in October 2002, the judge in the Rhode Island case
declared a mistrial after the jury declared itself deadlocked in the first phase
of the proposed multi-phase trial. In March 2003, the court denied motions for
judgment as a matter of law filed by both sides. The first phase is expected to
be retried during the first half of 2004.

    While we believe that we have valid defenses to all the lead-based paint and
lead pigment proceedings and are vigorously defending them, litigation is
inherently subject to many uncertainties. Additional lead-based paint and lead
pigment litigation may be filed against us in the future asserting similar or
different legal theories and seeking similar or different types of damages and
relief and any liability we incur with respect to these matters could be
material. 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.

    Due to the uncertainties involved, we are 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 the litigation against us. 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. As indicated above, we have not accrued any amounts for such
litigation.

OTHER PROCEEDINGS AND CLAIMS COULD REQUIRE US TO EXPEND MATERIAL AMOUNTS IN
LITIGATION AND SETTLEMENT COSTS AND JUDGMENTS.

    In addition to the environmental matters and lead-based paint and lead
pigment litigation referred to above, Millennium Chemicals and certain of its
subsidiaries are defendants in a number of pending legal proceedings relating to
their present and former operations. Several of these legal proceedings allege
injurious exposure of the plaintiffs to various chemicals and other materials,
including asbestos, on the premises of, or manufactured by, Millennium
Chemicals' current and former subsidiaries. For example, Millennium
Petrochemicals is one of a number of defendants in approximately 50 active,
premises-based asbestos cases (i.e., where the alleged exposure to
asbestos-containing materials was to employees of third-party contractors or
subcontractors on the premises of certain facilities, and did not relate to any
products manufactured or sold by us or any of our predecessors). These cases
typically involve multiple plantiffs. Millennium Chemicals is responsible for
these cases under its agreements with Equistar, which require Millennium
Petrochemicals to assume responsibility and indemnify Equistar for them.
However, under these agreements, Equistar will be required to assume
responsibility and indemnify Millennium Petrochemicals for any cases filed on or
after December 1, 2004 arising out of assets contributed to Equistar. In
addition, Millennium Chemicals is one of a number of defendants in approximately
50 asbestos cases in connection with the operations of one of its subsidiaries
and certain alleged predecessors at other facilities which also typically
involve multiple plaintiffs. Additional cases may be filed in the future for
which Millennium Chemicals may be responsible. We cannot assure you that any
liability we incur with respect to any present or future asbestos cases against
us will not be material to us (including taking into account insurance, which
will not be available for most of these cases).

                                       22






    On January 16, 2002, Slidell Inc. filed a lawsuit against Millennium
Inorganic Chemicals alleging breach of contract and other related causes of
action arising out of a contract between the two parties for the supply of
packaging equipment. We believe we have substantial defenses to these
allegations and have filed a counterclaim against Slidell. In addition,
Millennium Chemicals may be subject to potential unknown liabilities associated
with its present and former operations, including tax liabilities and
environmental liabilities, arising from the operations of its predecessors and
prior owners or operators of its sites or operations for which it may be
responsible.

    Although, based upon information currently available, we do not believe that
the outcome of the proceedings described above, either individually or in the
aggregate, will have a material adverse effect on our consolidated financial
position, results of operations or cash flows, litigation is subject to many
uncertainties and we cannot guarantee any particular result.

      retirement of long-lived assets. This standard requires that
      the fair value of a liability for an asset retirement
      obligation be recognized in the period in which it is
      incurred and the associated asset retirement costs be
      capitalized as part of the carrying amount of the long-lived
      asset. Accretion expense and depreciation expense related to
      the liability and capitalized asset retirement costs,
      respectively, are recorded in subsequent periods. The
      Company reported an after-tax transition charge of $1
      million as the cumulative effect of this accounting change.
      The impact of adoption was insignificant to the Company's
      reported assets and liabilities. The ongoing annual expense
      resulting from the initial adoption of SFAS No. 143 is not
      expected to be significant.

 (2)  During the fourth quarter of 2002, the Company changed from
      the last-in first-out ('LIFO') method to the first-in
      first-out ('FIFO') method of accounting for certain of its
      United States inventories in the Titanium Dioxide and
      Related Products business segment. The method was changed in
      part to achieve a better matching of revenues and expenses.
      The FIFO method, or methods that approximate FIFO, are now
      used to determine cost for all inventories of the Company.
      Information presented above has been restated for all
      periods presented to reflect the change from the LIFO to
      FIFO method. The restatement of the Company's results to
      reflect the accounting change from LIFO to FIFO had the
      following impact on net income (loss) for each of the
      periods presented above: decrease of $1 million for the
      three months ended March 31, 2002; increase of less than $1
      million in 2002; decrease of $4 million in 2001; increase of
      $2 million in 2000; decrease of $6 million in 1999; and
      increase of $7 million in 1998.

 (3)  On January 1, 2002, the Company adopted SFAS No. 142,
      'Goodwill and Other Inrtangible Assets' ('SFAS No. 142').
      Under this new standard, all goodwill, including goodwill
      acquired before initial application of the standard, is not
      amortized but must be tested for impairment at least
      annually at the reporting unit level, as defined in the
      standard. Accordingly, the Company reported a charge for the
      cumulative effect of this accounting change of $275 million
      in the first quarter of 2002 to write off certain of its
      goodwill related to its Acetyls business based upon the
      Company's estimate of fair value for this business using
      various valuation methods considering expected future
      profitability and cash flows. Also in accordance with SFAS
      No. 142, Equistar reported an impairment of its goodwill in
      the first quarter of


                                              (footnotes continued on next page)

                                       25






(footnotes continued from previous page)
      2002. The write-off at Equistar required an adjustment of
      $30 million to reduce the carrying value of the Company's
      investment in Equistar to its approximate proportional share
      of Equistar's Partners' capital. The Company reported this
      adjustment as a charge for the cumulative effect of a change
      in accounting principle. These charges reduced the carrying
      value of Millennium Chemicals' interest in Equistar by $30
      million and its total shareholders' equity by $305 million.
      Under this new standard, goodwill is not amortized.

 (4)  The results for the year ended December 31, 2002 were
      increased by a $6 million ($4 million after tax) adjustment
      of reserves for favorable resolution of environmental claims
      related to predecessor businesses reserved for in prior
      years and a benefit from a reduction in Millennium
      Chemicals' income tax accruals by $58 million due to
      favorable developments related to matters reserved for in
      prior years.

 (5)  Results for 2001 include a benefit from a reduction in
      Millennium Chemicals' income tax accruals by $42 million due
      to favorable developments related to matters reserved for in
      prior years; $36 million in reorganization and plant closure
      charges ($24 million after-tax); and $6 million ($4 million
      after-tax) representing Millennium Chemicals' share of costs
      related to the shutdown of Equistar's Port Arthur, Texas
      plant.

 (6)  The results for 1999 include a loss in value of Millennium
      Chemicals' Equistar interest of $639 million ($400 million
      after tax), to reduce the carrying value to estimated fair
      value.

 (7)  Total debt does not include the indemnity by Millennium
      America with respect to up to $750 million of Equistar's
      outstanding indebtedness, which indemnity terminated in
      August 2002 upon the closing of the purchase by Lyondell
      Chemical Company of Occidental Petroleum Corporation's
      interest in Equistar.

 (8)  For purposes of calculating the ratio of earnings to fixed
      charges, 'earnings' represent income from continuing
      operations before income taxes, minority interest and (loss)
      earnings on Equistar investment, plus fixed charges and cash
      distributions from Equistar. 'Fixed charges' consist of
      interest expense, including amortization of debt issuance
      costs and that portion of rental expenses which Millennium
      Chemicals considers to be a reasonable approximation of
      interest. The less than one-to-one coverage ratio for the
      year ended December 31, 2001 and the year ended
      December 31, 1999 results from the impact on (loss) income
      from continuing operations before income taxes and minority
      interest of a $36 million charge for reorganization and
      plant closures and a $639 million charge to write down the
      value of Millennium Chemicals' investment in Equistar,
      respectively. Excluding these charges, the 2001 ratio of
      earnings to fixed charges would have been .9x and the 1999
      ratio of earnings to fixed charges would have been 3.6x.
      Additional earnings of $6 million would have been required
      to achieve a one-to-one ratio for 2001, excluding
      reorganization and plant closure charges. Additional
      earnings of $12 million would have been required to achieve
      a one-to-one coverage ratio for the three months ended
      March 31, 2002.

 (9)  The pro forma ratio of earnings to fixed charges gives
      effect to the issuance of $100 million aggregate principal
      amount of outstanding unregistered 9 1/4% Senior Notes due
      2008 and the use of the gross proceeds from that offering to
      repay $85 million of outstanding indebtedness under the
      revolving credit facility under our bank credit agreement,
      as if this event had occurred on January 1, 2002.

                   DESCRIPTION OF CERTAIN OTHER INDEBTEDNESS

BANK CREDIT AGREEMENT

    We entered into a five-year Credit Agreement, dated as of June 18, 2001, as
amended on December 14, 2001, June 19, 2002 and April 25, 2003 (the 'Credit
Agreement'), among Millennium America, as a borrower, Millennium Inorganic
Chemicals Limited, as a borrower, certain borrowing subsidiaries of Millennium
Chemicals from time to time party thereto, Millennium Chemicals, as guarantor,
the lenders from time to time party thereto, the issuing banks from time to time
party thereto, JP Morgan Chase Bank (formerly known as The Chase Manhattan
Bank), as administrative agent and collateral agent ('JPM'), and Bank of
America, N.A., as syndication agent. The terms of the Credit Agreement provide
for: (a) a commitment to provide a secured revolving credit facility in an
aggregate principal amount of $175 million (the 'Revolving Loans'), and (b) a
secured term loan facility, of which $48 million was outstanding as of
March 31, 2003 (the 'Term Loans').

    The senior bank loans bear interest at either the Alternate Base Rate
('ABR') rate plus the spread (the 'ABR loans'), the LIBO rate plus the spread
(the 'LIBOR loans'), or the NIBO rate plus the spread (the 'NIBOR loans'). The
ABR rate is the highest of (i) the rate of interest publicly announced by JPM as
its prime rate in effect and (ii) the federal funds effective rate from time to
time plus 1/2 of 1.0%. The LIBO rate, with respect to any borrowing comprised of
LIBOR loans for any interest period, is an interest rate per annum equal to the
rate at which deposits in the currency of such borrowing approximately equal in
principal amount to the LIBOR loan of the administrative agent for which such
LIBO rate is being determined and for a maturity comparable to the applicable
interest period are offered in immediately available funds to the administrative
agent in the London interbank market. The NIBO rate, with respect to any
borrowing consisting of NIBOR loans for any interest period, is an interest rate
per annum equal to the interest rate at which U.S. dollar deposits approximately
equal in principal amount to the NIBOR loan of the administrative agent for
which the NIBO rate is being determined and for a maturity equal to the
applicable interest period are offered in immediately available funds to the
administrative agent at the eurodollar lending offices where its committed
foreign currency and exchange operations and eurodollar funding operations are
customarily conducted in the international interbank market. The spread refers
to the applicable per annum rate based upon the leverage ratio as set forth in
the pricing grid in the Credit Agreement. Interest on all borrowings is
calculated on the basis of the actual number of days elapsed over a 360-day year
(or a 365 or 366-day year, as applicable, for ABR borrowings accruing interest
based on the prime rate).

    Interest on the senior bank loans is payable on the last day of each March,
June, September, and December in the case of ABR loans, on the last day of the
applicable one, two or three month interest period in the case of one, two or
three month LIBOR loans and NIBOR loans, and in the case of LIBOR loans and
NIBOR loans having an interest period in excess of three months, on each
successive date three months after the first day of such interest period.

REVOLVING LOANS

    The Revolving Loans are available in U.S. dollars, pounds sterling, euros
and any other freely tradable currencies in the London market, which have been
approved by all the lenders participating in the revolving credit facility. The
Revolving Loans may be borrowed, repaid and reborrowed from time to time. A
letter of credit subfacility in an amount equal to $50 million is available
under the revolving credit facility. A swingline facility, in the amount of $25
million, is also available under the revolving credit facility. The total amount
of the Revolving Loans and swingline loans that may be borrowed is not permitted
to exceed $175 million (less the face amount of any letter of credit). The
Revolving Loans mature in June 2006.

                                       27






TERM LOANS

    The term loan facility amortizes in quarterly amounts in each year
commencing in 2002, with the substantial majority of the repayments being due in
2005 and 2006. Unless we meet a leverage ratio of less than 3.75 to 1.00, the
Term Loans are subject to mandatory prepayment upon the occurrence of certain
asset sales. We are permitted to voluntarily prepay the Term Loans in whole or
in part at any time subject to specified break funding costs that may be
applicable. We are not permitted to reborrow any amounts under the Term Loans
that we repay. The Term Loans mature in June 2006. As of March 31, 2003, there
were $48 million in Term Loans outstanding.

COVENANTS

    The Credit Agreement contains negative covenants, subject to specified
baskets, limiting the ability of Millennium Chemicals and/or certain
subsidiaries of Millennium Chemicals to, among other things:

            incur debt and issue preferred stock;

            create liens;

            engage in sale and leaseback transactions;

            declare or pay dividends on, and redeem, Millennium Chemicals'
            stock;

            make certain restricted payments;

            engage in certain transactions with affiliates;

            sell all or substantially all of the assets of Millennium Chemicals
            and its subsidiaries taken as a whole;

            engage in mergers or acquisitions;

            engage in domestic account receivable securitization transactions;
            and

            enter into certain restrictive agreements.

    The Credit Agreement requires us to comply with certain financial tests and
to maintain certain financial ratios relating to maximum consolidated leverage
and minimum consolidated interest coverage, the most significant of which are
set forth below. Failure to satisfy either of these financial covenants
constitutes a default under the Credit Agreement.

    The Credit Agreement also includes customary representations and warranties,
affirmative covenants and events of default, including (a) a cross-event of
default involving other material indebtedness, (b) failure of Millennium America
to remain a direct or indirect wholly owned subsidiary of Millennium Chemicals,
(c) a change of control of Millennium Chemicals and (d) other provisions
customary for this type of financing.

    Millennium Chemicals and Millennium America guarantee the obligations under
the Credit Agreement. The obligations are secured by: (1) a pledge of 100% of
the stock of Millennium Chemicals' existing and future domestic subsidiaries,
including Millennium America, and 65% of the stock of Millennium Chemicals'
existing and future first-tier foreign subsidiaries, in both cases other than
subsidiaries that hold immaterial assets, (2) all the equity interests held by
Millennium Chemicals' subsidiaries in Equistar and La Porte Methanol Company
(which pledge is limited to the right to receive distributions made by Equistar
and La Porte Methanol Company, respectively), and (3) all present and future
accounts receivable, intercompany indebtedness, and inventory of Millennium
Chemicals and its domestic subsidiaries other than subsidiaries that hold
immaterial assets.

    In April 2003, we obtained an amendment to our leverage and interest
coverage ratios that (1) requires that the leverage ratio (the ratio of Total
Indebtedness to EBITDA, each as defined, for the most recently ended period of
four fiscal quarters for which financial statements have been filed with the SEC
by Millennium Chemicals on Forms 10-K or 10-Q) of Millennium Chemicals

                                       28






and its consolidated subsidiaries on the last day of any fiscal quarter ending
during any period set forth below shall not be in excess of the ratio set forth
opposite that period:



                           PERIOD                                RATIO
                           ------                                -----
                                                           
January 1, 2003 through June 30, 2003.......................  5.75 to 1.00
July 1, 2003 through September 30, 2003.....................  5.50 to 1.00
October 1, 2003 through December 31, 2003...................  5.25 to 1.00
January 1, 2004 through June 30, 2004.......................  5.00 to 1.00
July 1, 2004 through December 31, 2004......................  4.75 to 1.00


and (2) requires that the interest coverage ratio (the ratio of EBITDA to Net
Interest Expense, each as defined) of Millennium Chemicals and its consolidated
subsidiaries for any period of four consecutive fiscal quarters ending during a
period set forth below shall not be less than the ratio set forth opposite that
period:



                           PERIOD                                RATIO
                           ------                                -----
                                                           
January 1, 2003 through December 31, 2003...................  2.25 to 1.00
January 1, 2004 through December 31, 2004...................  2.50 to 1.00


    For periods ending after January 1, 2005, the leverage ratio may not exceed
4.00 to 1.00 and the interest coverage ratio may not be less than 3.00 to 1.00
which is a return to levels originally set forth in the Credit Agreement.

SENIOR NOTES AND SENIOR DEBENTURES

    Millennium America has outstanding a $500,000,000 aggregate principal amount
of 7% senior notes due 2006 and $250,000,000 aggregate principal amount of
7.625% senior debentures due 2026. These notes and debentures are guaranteed by
Millennium Chemicals. The indenture under which these notes and debentures were
issued contains certain covenants that limit, among other things, the ability of
(1) Millennium America and its restricted subsidiaries (as defined in the
indenture) to grant liens or enter into sale-and-leaseback transactions,
(2) the restricted subsidiaries to incur additional indebtedness in excess of
15% of the Consolidated Net Tangible Assets, as defined in the indenture, of
Millennium America. In addition, such indenture contains a covenant that limits
the ability of Millennium America and Millennium Chemicals to merge, consolidate
or transfer substantially all of their respective assets.

    Millennium America has outstanding $475,000,000 aggregate principal amount
of 9 1/4% Senior Notes due 2008, guaranteed by Millennium Chemicals, including
the outstanding unregistered notes. These notes were issued, and the exchange
notes offered hereby will be issued, under the same indenture and are subject to
the same financial covenants.

                               THE EXCHANGE OFFER

PURPOSE OF THE EXCHANGE OFFER

    We sold the outstanding unregistered notes to the initial purchasers on
April 25, 2003. The initial purchasers subsequently resold those notes to
qualified institutional buyers pursuant to Rule 144A under the Securities Act
and to non-U.S. persons outside the United States in reliance on Regulation S
under the Securities Act. In connection with the issuance of the outstanding
unregistered notes, we and Millennium Chemicals entered into a registration
rights agreement with the initial purchasers of the outstanding unregistered
notes. The registration rights agreement requires us to register the exchange
notes under the Securities Act and offer to exchange the exchange notes for the
outstanding unregistered notes. The exchange notes will be issued without a
restrictive legend and generally may be resold without registration under the
federal securities laws. We are effecting the exchange offer to comply with the
registration rights agreement.

                                       29






    The registration rights agreement requires us to

     file with the SEC on or before July 24, 2003 a registration statement for
     the exchange offer and the exchange notes;

     use our reasonable efforts to cause the registration statement filed for
     the exchange offer and the exchange notes to be declared effective by the
     SEC on or before October 22, 2003;

     complete the exchange offer on or before November 21, 2003.

    These requirements under the registration rights agreement will be satisfied
when we complete the exchange offer. However, if we fail to meet any of these
requirements, we must pay liquidated damages to the holders of the outstanding
unregistered notes at the rate of $0.192 per week per $1,000 principal amount
until the applicable requirement has been met. We have also agreed to keep the
registration statement for the exchange offer effective for at least 30 days (or
longer, if required by applicable law) after the date on which notice of the
exchange offer is mailed to holders.

    Under the registration rights agreement, our obligations to register the
exchange notes will terminate upon the completion of the exchange offer.
However, we will be required to file a 'shelf' registration statement for a
continuous offering by the holders of the outstanding unregistered notes if:

     because of any change in law or applicable interpretations thereof by the
     staff of the SEC, Millennium America is not permitted to effect the
     exchange offer as contemplated by the registration rights agreement;

     any outstanding unregistered notes validly tendered pursuant to the
     exchange offer are not exchanged for exchange notes by November 21, 2003;

     any initial purchaser of the outstanding unregistered notes so requests
     with respect to outstanding unregistered notes not eligible to be exchanged
     for exchange notes in the exchange offer;

     any applicable law or interpretations do not permit any holder of
     outstanding unregistered notes to participate in the exchange offer;

     any holder of outstanding unregistered notes that participates in the
     exchange offer does not receive freely transferable exchange notes in
     exchange for tendered notes; or

     we so elect.

    If we are required to file a shelf registration statement, we will be
required to use our reasonable efforts to keep the registration statement
effective for two years, subject to some exceptions. Additionally, we will have
the ability to issue a notice that the shelf registration statement is unusable
pending a material announcement and may issue any notice suspending use of the
shelf registration statement without accruing liquidated damages so long as the
aggregate number of days in any consecutive twelve-month period for which all
notices are issued and effective does not exceed 60 days in total. Other than as
described above, no holder will have the right to require us to file a shelf
registration statement or otherwise register such holder's notes under the
federal securities laws.

    The registration rights agreement also provides that we and Millennium
Chemicals

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

     shall pay all expenses incident to the exchange offer (including the
     expense of one counsel to the holders of the exchange notes) and will
     indemnify certain holders of the exchange notes (including any
     broker-dealer) against certain liabilities, including liabilities under the
     Securities Act. A broker-dealer which delivers a prospectus to purchasers
     in connection with such resales will be subject to certain of the civil
     liability provisions under the Securities Act

                                       30






     and will be bound by the provisions of the registration rights agreement,
     including certain indemnification rights and obligations.

    Each broker-dealer that receives exchange notes for its own account in
exchange for outstanding unregistered notes, where such outstanding unregistered
notes were acquired by such broker-dealer as a result of market-making
activities or other trading activities, must acknowledge that it will deliver a
prospectus in connection with any resale of such exchange notes. Any
broker-dealer who acquired outstanding unregistered notes directly from us may
not rely on the interpretations of the SEC and must comply with the registration
and prospectus delivery requirements of the Securities Act. See 'Plan of
Distribution.'

    A holder who sells notes pursuant to a shelf registration statement will
generally be required to provide us with specific information, be named as a
selling security holder in the related prospectus and deliver a prospectus to
purchasers, will be subject to certain of the civil liability provisions under
the Securities Act in connection with such sales and will be bound by the
provisions of the registration rights agreement which are applicable to such a
holder, including certain indemnification obligations.

    This summary includes only the material terms of the registration rights
agreement. For a full description, you should refer to the complete copy of the
registration rights agreement, which has been filed as an exhibit to the
registration statement for the exchange offer and the exchange notes of which
this prospectus is a part. See 'Where You Can Find More Information.'

TRANSFERABILITY OF THE EXCHANGE NOTES

    Based on an interpretation of the Securities Act by the staff of the SEC in
several no-action letters issued to third parties, we believe that the holders
of the exchange notes, may offer for resale, resell or otherwise transfer the
exchange notes without further compliance with the registration and prospectus
delivery provisions of the Securities Act, if

     you, or the person or entity receiving such notes, are acquiring the
     exchange notes in the ordinary course of business;

     neither you nor any such person or entity is engaging in or intends to
     engage in a distribution of the exchange notes within the meaning of the
     Securities Act;

     neither you nor any such person or entity has an arrangement or
     understanding with any person or entity to participate in any distribution
     of the exchange notes;

     neither you nor any such person or entity is an 'affiliate' of Millennium
     Chemicals, as such term is defined under Rule 405 under the Securities Act;
     and

     you are not acting on behalf of any person or entity who could not
     truthfully make these statements.

    To participate in the exchange offer, you must represent as the holder of
outstanding unregistered notes that each of these statements is true.

    Any holder of the outstanding unregistered notes who is an affiliate of
Millennium Chemicals or who intends to participate in the exchange offer for the
purpose of distributing the exchange notes

     will not be able to rely on the interpretation by the staff of the SEC set
     forth in the no-action letters described above;

     will not be able to tender outstanding unregistered notes in the exchange
     offer; and

     must comply with the registration and prospectus delivery requirements of
     the Securities Act in connection with any sale or transfer of the notes,
     unless the sale or transfer is made pursuant to an exemption from those
     requirements.

    Broker-dealers receiving exchange notes in exchange for outstanding
unregistered notes acquired for their own account through market-making or other
trading activities may not rely on this interpretation by the SEC. Such
broker-dealers may be deemed to be 'underwriters' within

                                       31






the meaning of the Securities Act and must therefore acknowledge, by signing the
letter of transmittal, that they will deliver a prospectus meeting the
requirements of the Securities Act in connection with resale of the exchange
notes. The letter of transmittal states that by acknowledging that it will
deliver, and by delivering, a prospectus, a broker-dealer will not be deemed to
admit that it is an 'underwriter' within the meaning of the Securities Act. The
SEC has taken the position that participating broker-dealers may fulfill their
prospectus delivery requirements with respect to the exchange notes, other than
a resale of an unsold allotment from the original sale of the outstanding
unregistered notes, with the prospectus contained in the exchange offer
registration statement. As described above, under the registration rights
agreement, we have agreed to allow participating broker-dealers and other
persons, if any, subject to similar prospectus delivery requirements to use the
prospectus contained in the exchange offer registration statement in connection
with the resale of the exchange notes. Any broker-dealer who acquired
outstanding unregistered notes directly from us may not rely on the
interpretations of the SEC and must comply with the registration and prospectus
delivery requirements of the Securities Act. See 'Plan of Distribution.'

TERMS OF THE EXCHANGE OFFER; ACCEPTANCE OF TENDERED NOTES

    Upon the terms and subject to the conditions in this prospectus and in the
letter of transmittal, we will accept any and all outstanding unregistered notes
validly tendered and not withdrawn prior to 5:00 p.m., New York City time, on
         , 2003. We will issue $1,000 principal amount of exchange notes in
exchange for each $1,000 principal amount of outstanding unregistered notes
accepted in the exchange offer. Holders may tender some or all of their notes
pursuant to the exchange offer. However, outstanding unregistered notes may be
tendered only in integral multiples of $1,000.

    The form and terms of the exchange notes are the same as the form and terms
of the outstanding unregistered notes except that

     the exchange notes have been registered under the Securities Act and will
     not bear any legend restricting their transfer;

     the exchange notes bear a different CUSIP number from the outstanding
     unregistered notes; and

     the holders of the exchange notes will not be entitled to certain rights
     under the registration rights agreement, including the provisions for
     liquidated damages on the outstanding unregistered notes in some
     circumstances relating to the timing of the exchange offer.

    The exchange notes will evidence the same debt as the outstanding
unregistered notes. Holders of exchange notes will be entitled to the benefits
of the indenture.

    As of the date of this prospectus, $100 million aggregate principal amount
of unregistered notes was outstanding. There will be no fixed record date for
determining the holders of outstanding unregistered notes entitled to
participate in this exchange offer. We intend to conduct the exchange offer in
accordance with the applicable requirements of the Securities Exchange Act of
1934 and the rules and regulations of the SEC under the Exchange Act.

    We shall be deemed to have accepted validly tendered notes when, as, and if
we have given oral or written notice to the exchange agent of our acceptance.
The exchange agent will act as agent for the tendering holders for the purpose
of receiving the exchange notes from us. If any tendered notes are not accepted
for exchange because of an invalid tender, the occurrence of other events in
this prospectus or otherwise, we will return the certificates for any unaccepted
notes to the tendering holder as promptly as practicable after the expiration of
the exchange offer.

    Holders who tender exchange notes in the exchange offer will not be required
to pay brokerage commissions or fees with respect to the exchange of notes.
Tendering holders will also not be required to pay transfer taxes in the
exchange offer. We will pay all charges and expenses in connection with the
exchange offer as described under the subheading ' -- Solicitation of Tenders;
Fees and Expenses.' However, we will not pay any taxes incurred in connection
with

                                       32






a holder's request to have exchange notes or non-exchanged notes issued in the
name of a person other than the registered holder. See ' -- Transfer Taxes' in
this section below.

EXPIRATION DATE; EXTENSIONS; AMENDMENT

    The exchange offer will expire at 5:00 p.m., New York City time, on
         , 2003, unless we, in our sole discretion, extend the exchange offer.
To extend the exchange offer, we will notify the exchange agent and each
registered holder of any extension before 9:00 a.m., New York City time, on the
next business day after the previously scheduled expiration date. We reserve the
right to extend the exchange offer, delay accepting any tendered notes or, if
any of the conditions described below under the heading ' -- Conditions to the
Exchange Offer' have not been satisfied, to terminate the exchange offer. We
also reserve the right to amend the terms of the exchange offer in any manner.
We will give oral or written notice of such delay, extension, termination or
amendment to the exchange agent.

    Without limiting the manner in which we may choose to make public
announcements of any delay in acceptance, extension, termination or amendment of
the exchange offer, we will have no obligation to publish, advertise or
otherwise communicate any such public announcement, other than by making a
timely release to a financial news service.

INTEREST ON THE EXCHANGE NOTES

    The exchange notes will bear interest from the most recent interest payment
date to which interest has been paid on the tendered outstanding unregistered
notes or, if no interest has been paid, from April 25, 2003. Interest on the
outstanding unregistered notes accepted for exchange will cease to accrue upon
the issuance of the exchange notes.

    Interest on the notes is payable semi-annually on each June 15 and
December 15, commencing on          , 2003.

PROCEDURES FOR TENDERING OUTSTANDING UNREGISTERED NOTES

    Only a holder of outstanding unregistered notes may tender notes in the
exchange offer. To tender in the exchange offer, you must

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

     have the signatures guaranteed if required by the letter of transmittal;
     and

     mail or otherwise deliver the letter of transmittal or such facsimile,
     together with the outstanding unregistered notes and any other required
     documents, to the exchange agent prior to 5:00 p.m., New York City time, on
     the expiration date.

To tender outstanding unregistered notes effectively, you must complete the
letter of transmittal and other required documents and the exchange agent must
receive all the documents prior to 5:00 p.m., New York City time, on the
expiration date. Delivery of the outstanding unregistered notes may be made by
book-entry transfer in accordance with the procedures described below. The
exchange agent must receive confirmation of book-entry transfer prior to the
expiration date.

    By executing the letter of transmittal you will make to us the
representations set forth in the first paragraph under the heading
' -- Transferability of the Exchange Notes.'

    All tenders not withdrawn before the expiration date and the acceptance of
the tender by us will constitute agreement between you and us under the terms
and subject to the conditions in this prospectus and in the letter of
transmittal including an agreement to deliver good and marketable title to all
tendered notes prior to the expiration date free and clear of all liens,
charges, claims, encumbrances, adverse claims and rights and restrictions of any
kind.

   THE METHOD OF DELIVERY OF OUTSTANDING UNREGISTERED NOTES AND THE LETTER OF
   TRANSMITTAL AND ALL OTHER REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT THE
   ELECTION AND SOLE RISK OF THE HOLDER. INSTEAD OF DELIVERY BY MAIL, YOU SHOULD
   USE AN OVERNIGHT OR HAND DELIVERY SERVICE. IN ALL CASES, YOU SHOULD ALLOW FOR
   SUFFICIENT TIME TO ENSURE DELIVERY TO

                                       33






   THE EXCHANGE AGENT BEFORE THE EXPIRATION OF THE EXCHANGE OFFER. YOU MAY
   REQUEST YOUR BROKER, DEALER, COMMERCIAL BANK, TRUST COMPANY OR NOMINEE TO
   EFFECT THESE TRANSACTIONS FOR YOU. YOU SHOULD NOT SEND ANY NOTE, LETTER OF
   TRANSMITTAL OR OTHER REQUIRED DOCUMENT TO US.

    If your notes are registered in the name of a broker, dealer, commercial
bank, trust company or other nominee and you desire to tender, you should
contact the registered holder promptly and instruct the registered holder to
tender on your behalf. If you wish to tender on your own behalf, you must,
before completing and executing the letter of transmittal and delivering your
outstanding unregistered notes, either

     make appropriate arrangements to register ownership of the outstanding
     unregistered notes in your name, or

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

    See 'Instruction to Registered Holder and/or Book-Entry Transfer Facility
Participant from Beneficial Owner' included with the letter of transmittal.

    The exchange of notes will be made only after timely receipt by the exchange
agent of certificates for outstanding unregistered notes, a letter of
transmittal and all other required documents, or timely completion of a
book-entry transfer. If any tendered notes are not accepted for any reason or if
outstanding unregistered notes are submitted for a greater principal amount than
the holder desires to exchange, the exchange agent will return such unaccepted
or non-exchanged unregistered notes to the tendering holder promptly after the
expiration or termination of the exchange offer. In the case of outstanding
unregistered notes tendered by book-entry transfer, the exchange agent will
credit the non-exchanged notes to an account maintained with The Depository
Trust Company.

    Each broker-dealer that receives exchange notes for its own account in
exchange for outstanding unregistered notes, where such outstanding unregistered
notes were acquired by such broker-dealer as a result of market-making
activities or other trading activities, must acknowledge that it will deliver a
prospectus in connection with any resale of such exchange notes. See 'Plan of
Distribution'.

GUARANTEE OF SIGNATURES

    Holders must obtain a guarantee of all signatures on a letter of transmittal
or a notice of withdrawal unless the outstanding unregistered notes are tendered

     by a registered holder who has not completed the box entitled 'Special
     Issuance Instructions' or 'Special Delivery Instructions' on the letter of
     transmittal; or

     for the account of an 'eligible guarantor institution.'

Signature guarantees must be made by a member of or participant in the
Securities Transfer Agents Medallion Program, the New York Stock Exchange
Medallion Signature Program, the Stock Exchange Medallion Program, or by an
'eligible guarantor institution' within the meaning of Rule 17Ad-15 promulgated
under the Exchange Act (namely, banks; brokers and dealers; credit unions;
national securities exchanges; registered securities associations; learning
agencies; and savings associations).

SIGNATURE ON THE LETTER OF TRANSMITTAL; BOND POWERS AND ENDORSEMENTS

    If the letter of transmittal is signed by a person other than the registered
holder of the outstanding unregistered notes listed in the letter of
transmittal, the registered holder must endorse the outstanding unregistered
notes or provide a properly completed bond power. Any such endorsement or bond
power must be signed by the registered holder as that registered holder's name
appears on the outstanding unregistered notes. Signatures on such outstanding
unregistered notes and bond powers must be guaranteed by an 'eligible guarantor
institution.'

                                       34






    If you sign the letter of transmittal or any outstanding unregistered notes
or bond power as a trustee, executor, administrator, guardian, attorney-in-fact,
officer of a corporation, fiduciary or in any other representative capacity, you
must so indicate when signing. Unless we waive this condition, you must submit
satisfactory evidence to the exchange agent of your authority to act in such
capacity.

BOOK-ENTRY TRANSFER

    We understand that the exchange agent will make a request promptly after the
date of this prospectus to establish accounts with respect to the outstanding
unregistered notes at the book-entry transfer facility, The Depository Trust
Company, for the purpose of facilitating the exchange offer. Subject to the
establishment of the accounts, any financial institution that is a participant
in DTC's system may make book-entry delivery of outstanding unregistered notes
by causing DTC to transfer the notes into the exchange agent's account in
accordance with DTC's procedures for such transfer. However, although delivery
of outstanding unregistered notes may be effected through book-entry transfer
into the exchange agent's account at DTC, the letter of transmittal (or a
manually signed facsimile of the letter of transmittal) with any required
signature guarantees, or an 'agent's message' in connection with a book-entry
transfer, and any other required documents, must, in any case, be transmitted to
and received by the exchange agent, or the guaranteed delivery procedures set
forth below must be complied with, in each case, prior to the expiration date.
Delivery of documents to DTC does not constitute delivery to the exchange agent.

    The exchange agent and DTC have confirmed that the exchange offer is
eligible for the DTC Automated Tender Offer Program. Accordingly, DTC
participants may electronically transmit their acceptance of the exchange offer
by causing DTC to transfer outstanding unregistered notes to the exchange agent
in accordance with DTC's Automated Tender Offer Program procedures for transfer.
Upon receipt of such holder's acceptance through the Automated Tender Offer
Program, DTC will edit and verify the acceptance and send an 'agent's message'
to the exchange agent for its acceptance. Delivery of tendered notes must be
made to the exchange agent pursuant to the book-entry delivery procedures set
forth above, or the tendering DTC participant must comply with the guaranteed
delivery procedures set forth below.

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

     DTC has received an express acknowledgment from the participant in DTC
     tendering notes subject to the book-entry confirmation;

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

     we may enforce such agreement against such participant.

DETERMINATION OF VALID TENDERS; OUR RIGHTS UNDER THE EXCHANGE OFFER

    All questions as to the validity, form, eligibility, time of receipt,
acceptance and withdrawal of tendered notes will be determined by us in our sole
discretion, which determination will be final and binding on all parties. We
expressly reserve the absolute right, in our sole discretion, to reject any or
all outstanding unregistered notes not properly tendered or any outstanding
unregistered notes the acceptance of which would, in the opinion of our counsel,
be unlawful. We also reserve the absolute right in our sole discretion to waive
or amend any conditions of the exchange offer or to waive any defects or
irregularities of tender for any particular note, whether or not similar defects
or irregularities are waived in the case of other notes. Our interpretation of
the terms and conditions of the exchange offer will be final and binding on all
parties. No alternative, conditional or contingent tenders will be accepted.
Unless waived, any defects or irregularities in connection with tenders of
outstanding unregistered notes must be cured by the tendering holder within such
time as we determine.

                                       35






    Although we intend to notify holders of defects or irregularities in tenders
of outstanding unregistered notes, neither we, the exchange agent or any other
person shall be under any duty to give notification of defects or irregularities
in such tenders or will incur any liability to holders for failure to give such
notification. Holders will be deemed to have tendered outstanding unregistered
notes only when such defects or irregularities have been cured or waived. The
exchange agent will return to the tendering holder, after the expiration of the
exchange offer, any outstanding unregistered notes that are not properly
tendered and as to which the defects have not been cured or waived.

GUARANTEED DELIVERY PROCEDURES

    If you desire to tender outstanding unregistered notes pursuant to the
exchange offer and (1) certificates representing such outstanding unregistered
notes are not immediately available, (2) time will not permit your letter of
transmittal, certificates representing such outstanding unregistered notes and
all other required documents to reach the exchange agent on or prior to the
expiration date, or (3) the procedures for book-entry transfer (including
delivery of an agent's message) cannot be completed on or prior to the
expiration date, you may nevertheless tender such notes with the effect that
such tender will be deemed to have been received on or prior to the expiration
date if all the following conditions are satisfied

     you must effect your tender through an 'eligible guarantor institution,'
     which is defined above under the heading ' -- Guarantee of Signatures';

     a properly completed and duly executed notice of guaranteed delivery, or an
     agent's message with respect to guaranteed delivery that is accepted by us,
     is received by the exchange agent on or prior to the expiration date as
     provided below; and

     the certificates for the tendered notes, in proper form for transfer (or a
     book-entry confirmation of the transfer of such notes into the exchange
     agent's account at DTC as described above), together with a letter of
     transmittal (or manually signed facsimile of the letter of transmittal)
     properly completed and duly executed, with any signature guarantees and any
     other documents required by the letter of transmittal or a properly
     transmitted agent's message, are received by the exchange agent within
     three New York Stock Exchange, Inc. trading days after the date of
     execution of the notice of guaranteed delivery.

    The notice of guaranteed delivery may be sent by hand delivery, facsimile
transmission or mail to the exchange agent and must include a guarantee by an
eligible guarantor institution in the form set forth in the notice of guaranteed
delivery.

    Upon request to the exchange agent, a notice of guaranteed delivery will be
sent to holders who wish to tender their outstanding unregistered notes
according to the guaranteed delivery procedures outlined above.

WITHDRAWAL RIGHTS

    Except as otherwise provided in this prospectus, you may withdraw tendered
outstanding unregistered notes at any time before 5:00 p.m., New York City time,
on          , 2003. For a withdrawal of tendered outstanding unregistered notes
to be effective, a written or facsimile transmission notice of withdrawal must
be received by the exchange agent on or prior to the expiration of the exchange
offer. For DTC participants, a written notice of withdrawal may be made by
electronic transmission through DTC's Automated Tender Offer Program. Any notice
of withdrawal must

     specify the name of the person having tendered the outstanding unregistered
     notes to be withdrawn;

     identify the outstanding unregistered notes to be withdrawn, including the
     certificate number(s) and principal amount of the outstanding unregistered
     notes, or, in the case of outstanding unregistered notes transferred by
     book-entry transfer, the name and number of the account at DTC;

                                       36






     be signed by the holder in the same manner as the original signature on the
     letter of transmittal by which such outstanding unregistered notes were
     tendered, with any required signature guarantees, or be accompanied by
     documents of transfer sufficient to have the trustee with respect to the
     outstanding unregistered notes register the transfer of such outstanding
     unregistered notes into the name of the person withdrawing the tender and a
     properly completed irrevocable proxy authorizing such person to effect such
     withdrawal on behalf of such holder; and

     specify the name in which the outstanding unregistered notes to be
     withdrawn are to be registered, if different from that of the registered
     holder.

    If certificates for outstanding unregistered notes have been delivered or
otherwise identified to the exchange agent, then, before the release of those
certificates, the withdrawing holder must also submit

     the serial numbers of the particular certificates to be withdrawn; and

     a signed notice of withdrawal with signatures guaranteed by an eligible
     institution unless the holder is an eligible institution.

    Any permitted withdrawal of outstanding unregistered notes may not be
rescinded. Any outstanding unregistered notes properly withdrawn will thereafter
be deemed not to have been validly tendered for purposes of the exchange offer.
The exchange agent will return any withdrawn outstanding unregistered notes
without cost to the holder promptly after withdrawal of the outstanding
unregistered notes. Holders may retender properly withdrawn outstanding
unregistered notes at any time before the expiration of the exchange offer by
following one of the procedures described above under the heading
' -- Procedures for Tendering Outstanding Unregistered Notes.'

CONDITIONS TO THE EXCHANGE OFFER

    Notwithstanding any other term of the exchange offer, we shall not be
required to accept for exchange, or exchange any exchange notes for, any
outstanding unregistered notes, and may terminate or amend the exchange offer as
provided in this prospectus before the expiration of the exchange offer, if
certain events occur, including the following:

     the exchange notes to be received will not be tradable by the holder
     without restrictions under the Securities Act or the Exchange Act and
     without material restrictions under the blue sky or securities laws of
     substantially all the states of the United States;

     any action or proceeding is instituted or threatened in any court or by or
     before any governmental agency with respect to the exchange offer which, in
     our reasonable judgment, might materially impair our ability to proceed
     with the exchange offer or materially impair the contemplated benefits of
     the exchange offer to us;

     any law, statute, rule, regulation or interpretation by the staff of the
     SEC is proposed, adopted or enacted, which, in our reasonable judgment,
     might impair our ability to proceed with the exchange offer or impair the
     contemplated benefits of the exchange offer to us; or

     any governmental approval has not been obtained, which we believe, in our
     reasonable judgment, is necessary for the consummation of the exchange
     offer as outlined in this prospectus.

    If we determine in our sole discretion that any of the conditions are not
satisfied, we may

     refuse to accept any outstanding unregistered notes and return all tendered
     outstanding unregistered notes to the tendering holders;

     extend the exchange offer and retain all outstanding unregistered notes
     tendered prior to the expiration of the exchange offer, subject, however,
     to the rights of holders to withdraw their outstanding unregistered notes;
     or

     waive such unsatisfied conditions of the exchange offer and accept all
     properly tendered outstanding unregistered notes which have not been
     withdrawn.

                                       37






    These conditions are for the sole benefit of us and Millennium Chemicals and
may be asserted or waived by us at any time in our sole discretion. Our failure
to exercise any of these rights at any time will not be deemed a waiver of such
rights. These rights will be ongoing and may be asserted by us at any time.

    In addition, we will not complete the exchange offer if any stop order is
threatened or issued with respect to the registration statement for the exchange
offer and the exchange notes. In any such event, we must make every reasonable
effort to obtain the withdrawal of any stop order at the earliest possible
moment.

EFFECT OF NOT TENDERING

    To the extent outstanding unregistered notes are tendered and accepted in
the exchange offer, the principal amount of outstanding unregistered notes will
be reduced by the amount so tendered and a holder's ability to sell untendered
outstanding unregistered notes could be adversely affected. In addition, after
the completion of the exchange offer, the outstanding unregistered notes will
remain subject to restrictions on transfer. Since the outstanding unregistered
notes have not been registered under the Securities Act, they bear a legend
restricting their transfer absent registration or the availability of a specific
exemption from registration. The holders of outstanding unregistered notes not
tendered will have no further registration rights, except for the limited
registration rights described above under the heading ' -- Purpose of the
Exchange Offer.'

    Accordingly, the outstanding unregistered notes not tendered may be resold
only

     to us or our subsidiaries;

     pursuant to a registration statement which has been declared effective
     under the Securities Act;

     for so long as the outstanding unregistered notes are eligible for resale
     pursuant to Rule 144A under the Securities Act to a person the seller
     reasonably believes is a qualified institutional buyer that purchases for
     its own account or for the account of a qualified institutional buyer to
     whom notice is given that the transfer is being made in reliance on
     Rule 144A; or

     pursuant to any other available exemption from the registration
     requirements of the Securities Act (in which case we and the trustee shall
     have the right to require the delivery of an opinion of counsel,
     certifications and/or other information satisfactory to us and the
     trustee), subject in each of the foregoing cases to any requirements of law
     that the disposition of the seller's property or the property of such
     investor account or accounts be at all times within its or their control
     and to compliance with any applicable state securities laws.

    Upon completion of the exchange offer, due to the restrictions on transfer
of the outstanding unregistered notes and the absence of such restrictions
applicable to the exchange notes, it is likely that the market, if any, for
outstanding unregistered notes will be relatively less liquid than the market
for exchange notes. Consequently, holders of outstanding unregistered notes who
do not participate in the exchange offer could experience significant diminution
in the value of their outstanding unregistered notes, compared to the value of
the exchange notes.

REGULATORY APPROVALS

    Other than the federal securities laws, there are no federal or state
regulatory requirements that we must comply with and there are no approvals that
we must obtain in connection with the exchange offer.

SOLICITATION OF TENDERS; FEES AND EXPENSES

    We will bear the expenses of soliciting tenders. We are mailing the
principal solicitation. However, our officers and regular employees and those of
our affiliates may make additional solicitations by telegraph, telecopy,
telephone or in person.

                                       38






    We have not retained any dealer-manager in connection with the exchange
offer. We will not make any payments to brokers, dealers, or others soliciting
acceptances of the exchange offer. However, we will pay the exchange agent
reasonable and customary fees for its services and will reimburse it for its
reasonable out-of-pocket expenses.

    We will pay the cash expenses incurred in connection with the exchange
offer. These expenses include the SEC registration fee, fees and expenses of the
exchange agent and trustee, accounting and legal fees and printing costs, among
others.

ACCOUNTING TREATMENT

    The exchange notes will be recorded at the same carrying value as the
outstanding unregistered notes. The carrying value is the aggregate gross
proceeds received from the sale of the unregistered notes as reflected in our
accounting records on the date of exchange. Accordingly, we will recognize no
gain or loss for accounting purposes. The expenses of the exchange offer will be
expensed over the term of the exchange notes.

TRANSFER TAXES

    We will pay all transfer taxes, if any, required to be paid in connection
with the exchange of the outstanding unregistered notes for the exchange notes.
However, holders who instruct us to register exchange notes in the name of, or
request that outstanding unregistered notes not tendered or not accepted for
exchange be returned to, a person other than the registered holder will be
responsible for the payment of any transfer tax arising from such transfer.

    If you do not submit satisfactory evidence of payment of those taxes with
the letter of transmittal, the amount of those transfer taxes will be billed to
the tendering holder.

    The Bank of New York, the trustee under the indenture, is serving as the
exchange agent for the exchange offer. ALL EXECUTED LETTERS OF TRANSMITTAL
SHOULD BE SENT TO THE EXCHANGE AGENT AT THE ADDRESS LISTED BELOW. Questions,

                       DESCRIPTION OF THE EXCHANGE NOTES

    Definitions of certain terms used in this Description of the Exchange Notes
may be found under the heading 'Certain Definitions.' For purposes of this
section unless the context otherwise requires, (i) the terms 'Issuer' and 'we'
refers only to Millennium America Inc. and not to any of its subsidiaries,
(ii) the term 'Company' refers only to Millennium Chemicals Inc., the indirect
parent company of the Issuer, and not to any of its subsidiaries, (iii) the term
'Exchange Notes' means the notes offered hereby together with the outstanding
9 1/4% Senior Notes due 2008 which have been registered under the Securities Act
(the 'Registered Notes') and (iv) the term 'Notes' means the Exchange Notes
together with the outstanding 9 1/4% Senior Notes due 2008 which have not been
registered under the Securities Act (the 'Unregistered Notes'). The Company will
guarantee the Exchange Notes and therefore will be subject to many of the
provisions contained in this Description of the Exchange Notes. The Company's
guarantee is termed the 'Note Guarantee.'

    On April 25, 2003 we issued $100 million aggregate principal amount of
Unregistered Notes under an indenture, dated June 18, 2001 (the 'Indenture'),
among the Issuer, the Company and The Bank of New York, as Trustee (the
'Trustee'), a copy of which is incorporated by reference as an exhibit to the
registration statement of which this prospectus is a part and is available upon
request to the Company. The Exchange Notes offered hereby will be issued under
the Indenture, which is qualified under the U.S. Trust Indenture Act of 1939, as
amended. The Indenture contains provisions which define your rights under the
Exchange Notes. In addition, the Indenture governs the obligations of the Issuer
and the Company under the Exchange Notes. The terms of the Exchange Notes
include those stated in the Indenture and those made part of the Indenture by
reference to the TIA and are the same in all material respects as those of the
Unregistered Notes, except that the Exchange Notes will be registered under the
Securities Act and, therefore, will not bear legends restricting transfer.

    The Exchange Notes offered hereby will constitute 'Additional Securities'
under the Indenture. The Exchange Notes offered hereby, the outstanding
Unregistered Notes and Registered Notes, and any Additional Securities issued in
the future, will constitute the same series of securities and will vote together
as one series on all matters with respect to the Notes, including with respect
to the provisions of the Indenture described below under 'Defaults' and
'Amendments and Waivers.'

    The following description is meant to be only a summary of certain
provisions of the Indenture. It does not restate the terms of the Indenture in
their entirety. We urge that you carefully read the Indenture as it, and not
this description, governs your rights as Holders.

     will be effectively subordinated to any secured Indebtedness of the Company
     and its Subsidiaries to the extent of the value of the assets securing such
     Indebtedness; and

     will be effectively subordinated to all liabilities (including Trade
     Payables) and Preferred Stock of each Subsidiary of the Company (other than
     the Issuer).

    The Exchange Notes will not be guaranteed by any of the Company's
subsidiaries. As of March 31, 2003, these subsidiaries (other than the Issuer)
had approximately $24 million of total indebtedness outstanding (exclusive of
unused commitments and $9 million of undrawn outstanding standby letters of
credit), had approximately $240 million of trade payables outstanding, and held
approximately 99% of the Company's consolidated assets. For the year ended
December 31, 2002, these subsidiaries generated approximately 100% of the
Company's consolidated net sales.

PRINCIPAL, MATURITY AND INTEREST

    Up to an aggregate principal amount of $100 million of Exchange Notes will
be issued in the exchange offer. Additional notes in an unlimited amount may be
issued under the Indenture from time to time, subject to the covenants under the
Indenture and our other debt instruments in effect from time to time. The
outstanding Unregistered Notes, the Exchange Notes, and any additional Notes
subsequently issued (sometimes collectively referred to as the 'Notes') will be
treated as a single class for all purposes under the Indenture.

    The outstanding Unregistered Notes and Exchange Notes will mature on
June 15, 2008. We will issue the Exchange Notes in fully registered form,
without coupons, in denominations of $1,000 and any integral multiple of $1,000.

    Each Exchange Note we issue pursuant to the exchange offer will bear
interest at a rate of 9 1/4% per annum from the most recent interest payment
date to which interest has been paid on the tendered outstanding unregistered
notes, or if no interest has been paid, from April 25, 2003. We will pay
interest semiannually to Holders of record at the close of business on the
June 1 or December 1 immediately preceding the interest payment date on and of
each year. We will begin paying interest to Holders of the Exchange Notes
offered hereby on June 15, 2003. We will pay interest on overdue principal at 1%
per annum in excess of such rate, and we will pay interest on overdue
installments of interest at such higher rate to the extent lawful.

    We will also pay liquidated damages to Holders of the outstanding
Unregistered Notes, but not the Exchange Notes, if certain conditions are not
satisfied. These liquidated damage provisions are more fully explained under the
heading 'The Exchange Offer' above.

PAYMENTS ON THE EXCHANGE NOTES

    We will pay the principal of, premium, if any, interest and liquidated
damages, if any, on the Exchange Notes, and the Exchange Notes may be exchanged
or transferred, at any office of ours or any agency designated by us which is
located in the Borough of Manhattan, the City of New York. We have initially
designated the corporate trust office of the Trustee to act as the agent of the
Issuer in such matters. The location of the corporate trust office of the
Trustee is 101 Barclay Street, New York, New York 10286. We, however, reserve
the right to pay interest to Holders by check mailed directly to Holders at
their registered addresses. No service charge will be made for any registration
of transfer or exchange of Exchange Notes. We, however, may require Holders to
pay any transfer tax or other similar governmental charge payable in connection
with any such transfer or exchange.

TRANSFER AND EXCHANGE

    A Holder will be able to transfer or exchange Exchange Notes in accordance
with the Indenture. Upon any transfer or exchange, the registrar and the Trustee
may require a Holder, among other things, to furnish appropriate endorsements
and transfer documents and the Issuer

                                       41






may require a Holder to pay any taxes and fees required by law or permitted by
the Indenture. The Issuer will not be required to transfer or exchange any
Exchange Note selected for redemption or to transfer or exchange any Exchange
Note for a period of 15 days prior to a selection of Exchange Notes to be
redeemed. The Exchange Notes will be issued in registered form and the
registered Holder will be treated as the owner of such Exchange Note for all
purposes.

PAYING AGENT AND REGISTRAR

    The Trustee will initially act as paying agent and registrar. We may change
the paying agent or registrar without prior notice to the Holder of the Exchange
Notes, and the Company or any of its Subsidiaries may act as paying agent or
registrar.

OPTIONAL REDEMPTION

    The Exchange Notes may be redeemed, in whole at any time or in part from
time to time, at the option of the Issuer, upon not less than 30 nor more than
60 days' prior notice mailed by first-class mail to each Holder's registered
address, at a redemption price equal to the greater of (i) 100% of the principal
amount thereof plus accrued and unpaid interest and liquidated damages thereon,
if any, to the redemption date (subject to the right of Holders of record on the
relevant record date to receive interest due on the relevant interest payment
date) and (ii) the sum of (x) the present values of the remaining scheduled
payments of principal and interest thereon from the redemption date to the
maturity date (except for currently accrued but unpaid interest) discounted to
the redemption date on a semi-annual basis (assuming a 360-day year consisting
of twelve 30-day months) at the Treasury Rate plus 50 basis points and (y)
accrued and unpaid interest, if any, to the redemption date.

    In addition, prior to June 15, 2004, we may, on one or more occasions,
redeem up to a maximum of 35% of the aggregate principal amount of the Exchange
Notes (calculated after giving effect to any issuance of additional Notes) with
the Net Cash Proceeds of one or more Equity Offerings by the Company to the
extent the Net Cash Proceeds thereof are contributed to the Issuer or used to
purchase Capital Stock (other than Disqualified Stock) of the Issuer from the
Issuer, at a redemption price equal to 109.25% of the principal amount thereof,
plus accrued and unpaid interest and liquidated damages thereon, if any, to the
redemption date (subject to the right of Holders of record on the relevant
record date to receive interest due on the relevant interest payment date);
provided, however, that after giving effect to any such redemption:

        (1) at least 65% of the aggregate principal amount of the Exchange Notes
    (calculated after giving effect to any issuance of additional Notes) remains
    outstanding; and

        (2) any such redemption by the Company must be made within 60 days of
    such Equity Offering and must be made in accordance with certain procedures
    set forth in the Indenture.

    Except as set forth above, or under the caption 'Redemption for Changes in
Withholding Taxes,' we may not redeem the Notes.

SELECTION

    If we partially redeem Exchange Notes, the Trustee will select the Exchange
Notes to be redeemed in compliance with the requirements of the principal
national securities exchanges, if any, on which the Exchange Notes are listed,
on a pro rata basis, by lot or by such other method as the Trustee in its sole
discretion shall deem to be fair and reasonable, although no Exchange Note of
$1,000 in original principal amount or less will be redeemed in part. If we
redeem any Exchange Note in part only, the notice of redemption relating to such
Exchange Note shall state the portion of the principal amount thereof to be
redeemed. A new Exchange Note in principal amount equal to the unredeemed
portion thereof will be issued in the name of the Holder thereof upon
cancelation of the original Exchange Note. On and after the redemption date,
interest will cease to accrue on Exchange Notes or portions thereof called for
redemption so long

                                       42






as we have deposited with the paying agent funds sufficient to pay the principal
of, plus accrued and unpaid interest and liquidated damages thereon, if any, the
Exchange Notes to be redeemed.

MANDATORY REDEMPTION

    The Issuer is not required to make mandatory redemption payments or sinking
fund payments with respect to the Exchange Notes.

ADDITIONAL AMOUNTS

    The Issuer or the Company is required to make all payments under or with
respect to the Exchange Notes and the Note Guarantee free and clear of and
without withholding or deduction for or on account of any present or future tax,
duty, levy, impost, assessment or other governmental charge (including
penalties, interest and other liabilities related thereto) ('Taxes') imposed or
levied by or on behalf of the government of the United Kingdom or any political
subdivision or any authority or agency therein or thereof having power to tax,
or within any other jurisdiction in which we are organized or are otherwise
resident for tax purposes or any jurisdiction from or through which payment is
made (in each case, other than the United States or any political subdivision or
taxing authority thereof) (each a 'Relevant Taxing Jurisdiction'), unless the
Issuer or the Company is required to withhold or deduct Taxes by law or by the
interpretation or administration thereof.

    If the Issuer or the Company is so required to withhold or deduct any amount
for or on account of Taxes imposed by a Relevant Taxing Jurisdiction from any
payment made under or with respect to the Exchange Notes or the Note Guarantee,
the Issuer or the Company will be required to pay such additional amounts
('Additional Amounts') as may be necessary so that the net amount received by
you (including Additional Amounts) after such withholding or deduction will not
be less than the amount you would have received if such Taxes had not been
withheld or deducted; provided, however, that the foregoing obligation to pay
Additional Amounts does not apply to (1) any Taxes that would not have been so
imposed but for the existence of any present or former connection between the
relevant Holder (or between a fiduciary, settlor, beneficiary, member or
shareholder of, or possessor of power over the relevant holder, if the relevant
holder is an estate, nominee, trust or corporation) and the Relevant Taxing
Jurisdiction (other than the mere receipt of such payment or the ownership or
holding outside of the Relevant Taxing Jurisdiction of such Exchange Note); or
(2) any estate, inheritance, gift, sales, excise, transfer, personal property
tax or similar tax, assessment or governmental charge; nor will the Issuer or
the Company pay Additional Amounts (a) if the payment could have been made
without such deduction or withholding if the beneficiary of the payment had
presented the Exchange Note for payment within 30 days after the date on which
such payment or such Exchange Note became due and payable or the date on which
payment thereof is duly provided for, whichever is later (except to the extent
that the holder would have been entitled to Additional Amounts had the Exchange
Note been presented on the last day of such 30 day period), or (b) with respect
to any payment of principal of (or premium, if any, on) or interest on such
Exchange Note to any holder who is a fiduciary or partnership or any person
other than the sole beneficial owner of such payment, to the extent that a
beneficiary or settlor with respect to such fiduciary, a member of such a
partnership or the beneficial owner of such payment would not have been entitled
to the Additional Amounts had such beneficiary, settlor, member or beneficial
owner been the actual holder of such Exchange Note.

    Upon request, the Issuer or the Company will provide the Trustee with
official receipts or other documentation satisfactory to the Trustee evidencing
the payment of the Taxes with respect to which Additional Amounts are paid.

    Whenever in the Indenture there is mentioned, in any context:

        (1) the payment of principal;

        (2) purchase prices in connection with a purchase of Exchange Notes;

                                       43






        (3) interest; or

        (4) any other amount payable on or with respect to any of the Exchange
    Notes,

such reference shall be deemed to include payment of Additional Amounts as
described under this heading to the extent that, in such context, Additional
Amounts are, were or would be payable in respect thereof.

    The Issuer or the Company will pay any present or future stamp, court or
documentary taxes or any other excise or property taxes, charges or similar
levies that arise in any jurisdiction from the execution, delivery, enforcement
or registration of the Exchange Notes, the Note Guarantee, the Indenture or any
other document or instrument in relation thereof, or the receipt of any payments
with respect to the Exchange Notes or the Note Guarantee, excluding such taxes,
charges or similar levies imposed by any jurisdiction outside of the United
Kingdom, the jurisdiction of incorporation of any successor of the Company or
any jurisdiction in which a paying agent is located, and we will agree to
indemnify the Holders for any such taxes paid by such Holders.

    The obligations described under this heading will survive any termination,
defeasance or discharge of the Indenture and will apply mutatis mutandis to any
jurisdiction in which any successor Person to the Company is organized or any
political subdivision or taxing authority or agency thereof or therein (other
than the United States or any political subdivision or taxing authority
thereof).

REDEMPTION FOR CHANGES IN WITHHOLDING TAXES

    We are entitled to redeem the Exchange Notes, at our option, at any time as
a whole but not in part, upon not less than 30 nor more than 60 days' notice, at
100% of the principal amount thereof, plus accrued and unpaid interest (if any)
and liquidated damages to the date of redemption (subject to the right of
holders of record on the relevant record date to receive interest due on the
relevant interest payment date), in the event we have become or would become
obligated to pay, on the next date on which any amount would be payable with
respect to the Exchange Notes or the Note Guarantee, any Additional Amounts as a
result of:

        (1) a change in or an amendment to the laws (including any regulations
    promulgated thereunder) of any Relevant Taxing Jurisdiction; or

        (2) any change in or amendment to any official position regarding the
    application or interpretation of such laws or regulations, which change or
    amendment is announced or becomes effective on or after the date of this
    offering memorandum

and we cannot avoid such obligation by taking reasonable measures available to
us.

    Before we publish or mail notice of redemption of the Exchange Notes as
described above, we will deliver to the Trustee an officers' certificate to the
effect that we cannot avoid our obligation to pay Additional Amounts by taking
reasonable measures available to us. We will also deliver an opinion of
independent legal counsel of recognized standing stating that we would be
obligated to pay Additional Amounts as a result of a change in tax laws or
regulations or the application or interpretation of such laws or regulations.

RANKING

    The Exchange Notes will be general unsecured Senior Indebtedness of the
Issuer, will rank equally in right of payment with all existing and future
Senior Indebtedness of the Issuer and will be senior in right of payment to all
future Subordinated Obligations of the Issuer. The Exchange Notes also will be
effectively subordinated to any secured Indebtedness of the Issuer and its
Subsidiaries to the extent of the value of the assets securing such secured
Indebtedness.

    The Note Guarantee will be general unsecured Senior Indebtedness of the
Company, will rank equally in right of payment with all existing and future
Senior Indebtedness of the Company and will be senior in right of payment to all
future Subordinated Obligations of the Company. The

                                       44






Note Guarantee will be effectively subordinated to any secured Indebtedness of
the Company and its Subsidiaries to the extent of the value of the assets
securing such secured Indebtedness.

    The Company, the indirect parent company of the Issuer, currently conducts
all of its operations through its Subsidiaries, and the Issuer currently
conducts all of its operations through its Subsidiaries. Creditors of such
Subsidiaries, including trade creditors, and preferred stockholders (if any) of
such Subsidiaries generally will have priority with respect to the assets and
earnings of such Subsidiaries over the claims of the creditors of the Company
and the Issuer, including Holders. The Exchange Notes, therefore, will be
effectively subordinated to the claims of creditors, including trade creditors,
and preferred stockholders (if any) of the Company's Subsidiaries (other than
the Issuer). Although the Indenture will limit the Incurrence of Indebtedness by
and the issuance of preferred stock of certain of our Subsidiaries, such
limitation is subject to a number of significant qualifications.

    As of March 31, 2003, on a pro forma basis, there would have been
outstanding:

        (1) $1,297 million of senior indebtedness of the Issuer (including the
    Notes), of which $48 million would have been secured indebtedness (exclusive
    of unused commitments under the Credit Agreement and $12 million of undrawn
    outstanding standby letters of credit);

        (2) $1,249 million of senior indebtedness of the Company (exclusive of
    guarantees of indebtedness under the Credit Agreement and $1 million of
    undrawn outstanding standby letters of credit), of which none would have
    been secured indebtedness;

        (3) no subordinated obligations of the Company or the Issuer; and

        (4) $240 million of trade payables and $24 million of total indebtedness
    outstanding (exclusive of unused commitments under the Credit Agreement and
    $9 million of undrawn outstanding standby letters of credit) of subsidiaries
    of the Company, other than the Issuer. In addition, since each of the
    Company and the Issuer conducts all of its operations through its
    subsidiaries, subsidiaries of the Company (other than the Issuer) had
    substantial operating liabilities.

        Although the Indenture will limit the Incurrence of Indebtedness by the
    Company and the Restricted Subsidiaries (including the Issuer) and the
    issuance of Preferred Stock by the Restricted Subsidiaries, such limitation
    is subject to a number of significant qualifications. The Company and its
    Subsidiaries may be able to incur substantial amounts of Indebtedness in
    certain circumstances. Such Indebtedness may be Senior Indebtedness.

THE NOTE GUARANTEE

    The Company, as primary obligor and not merely as surety, will irrevocably
and unconditionally Guarantee on an unsecured senior basis the performance and
full and punctual payment when due, whether at Stated Maturity, by acceleration
or otherwise, of all obligations of the Issuer under the Indenture (including
obligations to the Trustee) and the Exchange Notes, whether for payment of
principal of or interest on or liquidated damages in respect of the Exchange
Notes, expenses, indemnification or otherwise (all such obligations guaranteed
by the Company being herein called the 'Guaranteed Obligations'). The Company
will agree to pay, in addition to the amount stated above, any and all costs and
expenses (including reasonable counsel fees and expenses) incurred by the
Trustee or the Holders in enforcing any rights under the Note Guarantee. The
Note Guarantee will be limited in amount to an amount not to exceed the maximum
amount that can be Guaranteed by the Company without rendering the Note
Guarantee voidable under applicable law relating to fraudulent conveyance or
fraudulent transfer or similar laws affecting the rights of creditors generally.

    The Note Guarantee is a continuing guarantee and shall (a) remain in full
force and effect until payment in full of all the Guaranteed Obligations, (b) be
binding upon the Company and its successors and (c) inure to the benefit of, and
be enforceable by, the Trustee, the Holders and their successors, transferees
and assigns.

                                       45






CHANGE OF CONTROL

    Upon the occurrence of any of the following events (each a 'Change of
Control'), each Holder of Exchange Notes will have the right to require the
Issuer to purchase all or any part (equal to $1,000 or an integral multiple
thereof) of such Holder's Exchange Notes at a purchase price in cash equal to
101% of the principal amount thereof plus accrued and unpaid interest and
liquidated damages, if any, to the date of purchase (subject to the right of
Holders of record on the relevant record date to receive interest and liquidated
damages, if any, due on the relevant interest payment date):

        (1) any 'person' (as such term is used in Sections 13(d) and 14(d) of
    the Exchange Act), other than the Company or a Subsidiary of the Company, is
    or becomes the beneficial owner (as defined in Rules 13d-3 and 13d-5 under
    the Exchange Act, except that for purposes of this clause (1) such person
    shall be deemed to have 'beneficial ownership' of all shares that any such
    person has the right to acquire, whether such right is exercisable
    immediately or only after the passage of time), directly or indirectly, of
    more than 50% of the total voting power of the Voting Stock of the Issuer or
    the Company (for the purposes of this clause (1), such person shall be
    deemed to beneficially own any Voting Stock of an entity held by any other
    entity (the 'parent entity'), if such person is the beneficial owner (as
    defined in this clause (1)), directly or indirectly, of more than 50% of the
    voting power of the Voting Stock of such parent entity); or

        (2) during any period of two consecutive years, individuals who at the
    beginning of such period constituted the board of directors of the Issuer or
    the Company, as the case may be (together with any new directors whose
    election by such board of directors of the Issuer or the Company, as the
    case may be, or whose nomination for election by the shareholders of the
    Issuer or the Company, as the case may be, was approved by a vote of 66 2/3%
    of the directors of the Issuer or the Company, as the case may be, then
    still in office who were either directors at the beginning of such period or
    whose election or nomination for election was previously so approved) cease
    for any reason to constitute a majority of the board of directors of the
    Issuer or the Company, as the case may be, then in office; or

        (3) the adoption of a plan relating to the liquidation or dissolution of
    the Issuer or the Company; or

        (4) the merger or consolidation of the Issuer or the Company with or
    into another Person or the merger of another Person with or into the Issuer
    or the Company, or the sale of all or substantially all the assets of the
    Issuer or the Company to another Person, unless, in the case of any such
    merger or consolidation, the securities of the Issuer or the Company, as the
    case may be, that are outstanding immediately prior to such transaction and
    which represent 100% of the aggregate voting power of the Voting Stock of
    the Issuer or the Company, as the case may be, constitute or are changed
    into or exchanged for securities that constitute, in addition to any other
    consideration, securities of the surviving Person that represent immediately
    after such transaction at least a majority of the aggregate voting power of
    the Voting Stock of the surviving Person or transferee. For purposes of this
    clause (4), (i) the sale by the Company or the Issuer of the equity
    interests in Millennium Petrochemicals Inc., the equity interests in the
    limited liability companies which directly or indirectly own the Company's
    equity interests in Equistar, and/or the Company's equity interests in
    Equistar will be deemed not to constitute a sale of all or substantially all
    of the assets of the Issuer or the Company if any such sale consists of Net
    Tangible Assets constituting 33 1/3% or less of the Consolidated Net
    Tangible Assets of the Company as of the date of the most recent publicly
    available consolidated balance sheet of the Company and its Subsidiaries and
    (ii) it shall not be a Change of Control if the Issuer or the Company merges
    into the other or into a Restricted Subsidiary, or consolidates with or into
    the other or a Restricted Subsidiary, or sells all or substantially all of
    its assets to the other or a Restricted Subsidiary for internal
    restructuring purposes or in combination with another transaction which does
    not constitute a Change of Control.

                                       46






    In the event that at the time of such Change of Control the terms of the
Bank Indebtedness restrict or prohibit the repurchase of Exchange Notes pursuant
to this covenant, then prior to the mailing of the notice to Holders provided
for in the immediately following paragraph but in any event within 30 days
following any Change of Control, the Issuer shall:

        (1) repay in full all Bank Indebtedness or, if doing so will allow the
    purchase of Exchange Notes, offer to repay in full all Bank Indebtedness and
    repay the Bank Indebtedness of each lender who has accepted such offer; or

        (2) obtain the requisite consent under the agreements governing the Bank
    Indebtedness to permit the repurchase of the Exchange Notes as provided for
    in the immediately following paragraph.

    Within 30 days following any Change of Control, the Issuer shall mail a
notice to each Holder with a copy to the Trustee (the 'Change of Control Offer')
stating:

        (1) that a Change of Control has occurred and that such Holder has the
    right to require the Issuer to purchase all or a portion of such Holder's
    Exchange Notes at a purchase price in cash equal to 101% of the principal
    amount thereof, plus accrued and unpaid interest and liquidated damages, if
    any, to the date of purchase (subject to the right of Holders of record on
    the relevant record date to receive interest and liquidated damages, if any,
    on the relevant interest payment date);

        (2) the circumstances and relevant facts and financial information
    regarding such Change of Control;

        (3) the purchase date (which shall be no earlier than 30 days nor later
    than 60 days from the date such notice is mailed); and

        (4) the instructions determined by the Issuer, consistent with the
    Indenture, that a Holder must follow in order to have its Notes purchased.

    The Issuer will not be required to make a Change of Control Offer upon a
Change of Control if a third party makes the Change of Control Offer in the
manner, at the times and otherwise in compliance with the requirements set forth
in the Indenture applicable to a Change of Control Offer made by the Issuer and
purchases all Notes validly tendered and not withdrawn under such Change of
Control Offer.

    The Issuer will comply, to the extent applicable, with the requirements of
Section 14(e) of the Exchange Act and any other securities laws or regulations
in connection with the purchase of Exchange Notes pursuant to the Indenture. To
the extent that the provisions of any securities laws or regulations conflict
with provisions of the Indenture, the Issuer will comply with the applicable
securities laws and regulations and will not be deemed to have breached its
obligations under the Indenture by virtue thereof.

    The Change of Control purchase feature is a result of negotiations between
the Issuer, the Company and the initial purchasers in the offering of the 9 1/4%
Senior Notes due 2008 in June 2001. Neither management of the Issuer nor the
Company has a present intention to engage in a transaction involving a Change of
Control, although it is possible that the Issuer or the Company would decide to
do so in the future. Subject to the limitations discussed below, we could, in
the future, enter into certain transactions, including acquisitions,
refinancings or recapitalizations, that would not constitute a Change of Control
under the Indenture, but that could increase the amount of indebtedness
outstanding at such time or otherwise affect our capital structure or credit
ratings. Restrictions on our ability to Incur additional Indebtedness are
contained in the covenants described under 'Certain Covenants -- Limitation on
Indebtedness,' ' -- Limitation on Liens' and
' -- Limitation on Sale/Leaseback Transactions.' Such restrictions can only be
waived with the consent of the Holders of a majority in principal amount of the
Notes then outstanding. Except for the limitations contained in such covenants,
however, the Indenture does not contain any covenants or provisions that may
afford Holders protection in the event of a highly leveraged transaction.

                                       47






    The occurrence of certain of the events which would constitute a Change of
Control would constitute a default under the Credit Agreement. Future
Indebtedness of the Company and its Subsidiaries may contain prohibitions of
certain events which would constitute a Change of Control or require such
Indebtedness to be repurchased or repaid upon a Change of Control. Moreover, the
exercise by the Holders of their right to require the Issuer to purchase the
Exchange Notes could cause a default under such Indebtedness, even if the Change
of Control itself does not, due to the financial effect of such repurchase on
the Company and its Subsidiaries. Finally, the Issuer's ability to pay cash to
the Holders upon a purchase may be limited by the Issuer's then existing
financial resources. There can be no assurance that sufficient funds will be
available when necessary to make any required purchases. The provisions under
the Indenture relative to the Issuer's obligation to make an offer to purchase
the Exchange Notes as a result of a Change of Control may be waived or modified
with the written consent of the Holders of a majority in principal amount of the
Notes then outstanding.

    The definition of 'Change of Control' includes a disposition of all or
substantially all of the assets of the Company or the Issuer to any Person.
Although there is a limited body of case law interpreting the phrase
'substantially all,' there is no precise established definition of the phrase
under New York law (which is the governing law of the Indenture). Accordingly,
in certain circumstances there may be a degree of uncertainty as to whether a
particular transaction would involve a disposition of 'all or substantially all'
of the assets of a Person. As a result, it may be unclear as to whether a Change
of Control has occurred and whether a holder of Exchange Notes may require the
Issuer to make an offer to repurchase the Exchange Notes as described above.

CERTAIN COVENANTS

    The Indenture contains covenants including, among others, the following:

    Limitation on Indebtedness. (a) Subsequent to June 18, 2001, the Company
will not, and will not permit any Restricted Subsidiary to, Incur, directly or
indirectly, any Indebtedness; provided, however, that the Issuer or the Company
may Incur Indebtedness if on the date of such Incurrence and after giving effect
thereto the Consolidated Coverage Ratio would be greater than 2.00:1 if such
Indebtedness is Incurred on or prior to June 15, 2003 and 2.25:1 if such
Indebtedness is Incurred thereafter.

    (b) Notwithstanding the foregoing paragraph (a), the Company and its

           any Restricted Subsidiary upon such conversion or exchange);

                                       51

           Subsidiaries as Restricted Subsidiaries (valued in each case as
           provided in the definition of 'Investment') not to exceed, in the
           case of any Unrestricted Subsidiary, the amount of Investments
           previously made by the Company or any Restricted Subsidiary in such
           Unrestricted Subsidiary, which amount was included in the calculation
           of the amount of Restricted Payments;

       into in the ordinary course of business, so long as such encumbrances or
       restrictions are not applicable to any Person (or its property or assets)
       other than such joint venture or a Subsidiary thereof;

                                       54






           (L) in the case of clause (3), any Lien Incurred in compliance with
       the covenant described under ' -- Limitation on Liens'; and

           (M) customary restrictions imposed on the transfer of intellectual
       property in the ordinary course of business.

    Limitation on Sales of Assets and Subsidiary Stock. (a) Subsequent to
June 18, 2001, the Company will not, and will not permit any Restricted
Subsidiary to, make any Asset Disposition unless:

        (1) the Company or such Restricted Subsidiary receives consideration
    (including by way of relief from, or by any other Person assuming sole
    responsibility for, any liabilities, contingent or otherwise) at the time of
    such Asset Disposition at least equal to the Fair Market Value (determined
    either at the date of such Asset Disposition or at the date of the agreement
    providing for such Asset Disposition) of the shares and assets subject to
    such Asset Disposition,

        (2) at least 75% of the consideration thereof received by the Company or
    such Restricted Subsidiary is in the form of cash, and

        (3) an amount equal to 100% of the Net Available Cash from such Asset
    Disposition is applied by the Company (or such Restricted Subsidiary, as the
    case may be)

           (A) first, to the extent the Company elects (or is required by the
       terms of any Indebtedness), to prepay, repay, purchase, repurchase,
       redeem, retire, defease or otherwise acquire for value Bank Indebtedness
       of the Company or the Issuer or Indebtedness (other than obligations in
       respect of Preferred Stock) of a Wholly Owned Subsidiary other than the
       Issuer (in each case other than Indebtedness owed to the Company or an
       Affiliate of the Company and other than obligations in respect of
       Disqualified Stock) within 360 days after the later of the date of such
       Asset Disposition or the receipt of such Net Available Cash;

           (B) second, to the extent of the balance of Net Available Cash after
       application in accordance with clause (A), to the extent the Company or
       such Restricted Subsidiary elects, to reinvest in Additional Assets
       (including by means of an Investment in Additional Assets by a Restricted
       Subsidiary with Net Available Cash received by the Company or another
       Restricted Subsidiary) within 360 days from the later of such Asset
       Disposition or the receipt of such Net Available Cash;

           (C) third, to the extent of the balance of such Net Available Cash
       after application in accordance with clauses (A) and (B), to make an
       Offer (as defined in paragraph (b) of this covenant below) to purchase
       Notes pursuant to and subject to the conditions set forth in paragraph
       (b) of this covenant; provided, however, that if the Issuer elects (or is
       required by the terms of any other Senior Indebtedness), such Offer may
       be made ratably to purchase the Notes and other Senior Indebtedness of
       the Company or the Issuer, and

           (D) fourth, to the extent of the balance of such Net Available Cash
       after application in accordance with clauses (A), (B) and (C), for any
       general corporate purpose permitted by the terms of the Indenture;

provided, however, that in connection with any prepayment, repayment, purchase,
repurchase, redemption, retirement, defeasance or other acquisition for value of
Indebtedness pursuant to clause (A), (C) or (D) above, the Company or such
Restricted Subsidiary will retire such Indebtedness and will cause the related
loan commitment (if any) to be permanently reduced in an amount equal to the
principal amount so prepaid, repaid, purchased, repurchased, redeemed, retired,
defeased or otherwise acquired for value.

    Notwithstanding the foregoing provisions of this covenant, the Company and
the Restricted Subsidiaries will not be required to apply any Net Available Cash
in accordance with this covenant except to the extent that the aggregate Net
Available Cash from all Asset Dispositions that is not applied in accordance
with this covenant exceeds $5 million.

                                       55






    For the purposes of this covenant, the following are deemed to be cash:

         the assumption of Indebtedness of (i) the Issuer (other than
         obligations in respect of Disqualified Stock of the Issuer) or (ii) the
         Company or any Restricted Subsidiary other than the Issuer (other than
         obligations in respect of Disqualified Stock and Preferred Stock of the
         Company) and the release of the Issuer, the Company or such Restricted
         Subsidiary from all liability on such Indebtedness in connection with
         such Asset Disposition (it being understood that the assumption of the
         Issuer's Guarantee of Indebtedness of Equistar in effect on June 18,
         2001 shall be valued as $0 for the purposes of complying with clause
         (a)(2) of this covenant above) and

         securities received by the Company or any Restricted Subsidiary from
         the transferee that are converted, sold or exchanged within 30 days of
         receipt by the Company or such Restricted Subsidiary into cash to the
         extent of the cash received.

    (b) In the event of an Asset Disposition that requires the purchase of Notes
pursuant to clause (a)(3)(C) of this covenant, the Issuer will be required

        (i) to purchase Notes tendered pursuant to an offer by the Issuer for
    the Notes (the 'Offer') at a purchase price of 100% of their principal
    amount plus accrued and unpaid interest and liquidated damages thereon, if
    any, to the date of purchase (subject to the right of Holders of record on
    the relevant date to receive interest due on the relevant interest payment
    date) in accordance with the procedures (including prorating in the event of
    oversubscription) set forth in the Indenture; and

        (ii) to purchase other Senior Indebtedness of the Issuer or the Company
    on the terms and to the extent contemplated thereby (provided that in no
    event shall the Issuer offer to purchase such other Senior Indebtedness of
    the Issuer or the Company at a purchase price in excess of 100% of its
    principal amount (without premium), plus accrued and unpaid interest
    thereon.

    If the aggregate purchase price of Notes (and other Senior Indebtedness)
tendered pursuant to the Offer is less than the Net Available Cash allotted to
the purchase of the Notes (and other Senior Indebtedness), the Issuer will apply
the remaining Net Available Cash in accordance with clause (a)(3)(D) of this
covenant. The Issuer will not be required to make an Offer for Notes (and other
Senior Indebtedness) pursuant to this covenant if the Net Available Cash
available therefor (after application of the proceeds as provided in clauses
(a)(3)(A) and (B)) is less than $5 million for any particular Asset Disposition
(which lesser amount will be carried forward for purposes of determining whether
an Offer is required with respect to the Net Available Cash from any subsequent
Asset Disposition).

    (c) The Issuer will comply, to the extent applicable, with the requirements
of Section 14(e) of the Exchange Act and any other securities laws or
regulations in connection with the repurchase of Notes pursuant to this
covenant. To the extent that the provisions of any securities laws or
regulations conflict with provisions of this covenant, the Issuer will comply
with the applicable securities laws and regulations and will not be deemed to
have breached its obligations under this covenant by virtue thereof.

    Limitation on Transactions with Affiliates. (a) Subsequent to June 18, 2001,
the Company will not, and will not permit any Restricted Subsidiary to, directly
or indirectly, enter into or conduct any transaction or series of related
transactions (including the purchase, sale, lease or exchange of any property or
the rendering of any service) with any Affiliate of the Company (an 'Affiliate
Transaction') unless such transaction is on terms:

        (1) that are not materially less favorable to the Company or such
    Restricted Subsidiary, as the case may be, than those that could be obtained
    at the time of such transaction in arm's-length dealings with a Person who
    is not such an Affiliate,

        (2) that, in the event such Affiliate Transaction involves an aggregate
    amount in excess of $10 million,

           (A) are set forth in writing, and

                                       56






           (B) have been approved by a majority of the members of the Board of
       Directors of the Company having no personal stake in such Affiliate
       Transaction and,

        (3) that, in the event such Affiliate Transaction involves an amount in
    excess of $25 million, have been determined by a nationally recognized
    appraisal or investment banking firm to be fair, from a financial
    standpoint, to the Company and its Restricted Subsidiaries.

    (b) The provisions of the foregoing paragraph (a) will not prohibit or apply
to:

        (1) any Restricted Payment permitted to be paid pursuant to the covenant
    described under 'Limitation on Restricted Payments,'

        (2) any issuance of securities, or other payments, awards or grants in
    cash, securities or otherwise pursuant to, or the funding of, employment
    arrangements, stock options, stock ownership and other incentive
    compensation plans approved by the Board of Directors of the Company,

        (3) the payment of reasonable fees to, and indemnity provided on behalf
    of, directors, officers and employees of the Company and its Subsidiaries,

        (4) any transaction between the Company and a Restricted Subsidiary or
    between Restricted Subsidiaries,

        (5) transactions by the Company or any Restricted Subsidiary with
    Equistar or any Subsidiary thereof pursuant to any agreement as in effect as
    of June 18, 2001 or any amendment thereto or any similar agreement entered
    into after June 18, 2001; provided, however, that any future amendment to
    such existing agreement or any such similar agreement shall not be permitted
    by this clause (5) to the extent that the terms of any such amendment or
    similar agreement are materially less favorable to the Company, any of its
    Restricted Subsidiaries or the Holders of the Exchange Notes in any material
    respect,

        (6) any transaction by the Company or any Restricted Subsidiary with
    Equistar or any Subsidiary thereof that, taken as a whole with any other
    transactions by the Company or any Restricted Subsidiary with Equistar or
    any of its Subsidiaries that is entered into prior to or substantially
    concurrently with such transaction, is on terms that are not materially less
    favorable to the Company or such Restricted Subsidiary than those that could
    be obtained at the time of such transactions in arm's-length dealings with a
    Person which is not an Affiliate of the Company, or

        (7) any transaction effected as part of a Qualified Receivables
    Transaction.

    Limitation on the Sale or Issuance of Capital Stock of Restricted
Subsidiaries. Subsequent to June 18, 2001, the Company will not sell or
otherwise dispose of any shares of Capital Stock of a Restricted Subsidiary
(other than shares of Capital Stock constituting up to 5% of the outstanding
shares of Capital Stock of La Porte Methanol Company), and will not permit any
Restricted Subsidiary, directly or indirectly, to issue or sell or otherwise
dispose of any shares of its Capital Stock except:

        (1) to the Company or a Restricted Subsidiary;

        (2) if, immediately after giving effect to such issuance, sale or other
    disposition, neither the Company nor any of its Subsidiaries own any Capital
    Stock of such Restricted Subsidiary;

        (3) if, immediately after giving effect to such issuance, sale or other
    disposition, such Restricted Subsidiary would no longer constitute a
    Restricted Subsidiary and any Investment in such Person remaining after
    giving effect thereto would have been permitted to be made under the
    covenant described under 'Limitation on Restricted Payments' if made on the
    date of such issuance, sale or other disposition (and such Investment shall
    be deemed to be an Investment for the purposes of such covenant); or

        (4) if, immediately after giving effect to such issuance, sale or other
    disposition, such Restricted Subsidiary would continue to constitute a
    Restricted Subsidiary.

                                       57






    The proceeds of any sale of such Capital Stock permitted hereby (other than
pursuant to clause (1)) will be treated as Net Available Cash from an Asset
Disposition and must be applied in accordance with the terms of the covenant
described under 'Limitation on Sales of Assets and Subsidiary Stock.'

    Limitation on Liens. (a) Subsequent to June 18, 2001, the Company will not,
and will not permit any Restricted Subsidiary to, Incur Indebtedness secured by
a Lien upon any Restricted Property ('Secured Debt') without effectively and
concurrently providing that the Exchange Notes (and, if the Company or the
Issuer shall so determine, any other Indebtedness that is not subordinate in
right of payment to the Exchange Notes) shall be secured equally and ratably
with (or prior to) such Indebtedness so long as such Indebtedness shall be so
secured. This restriction will not apply to:

        (1) Liens existing on or prior to June 18, 2001 (other than Liens
    securing the Bank Indebtedness);

        (2) Liens affecting property of a Person existing at the time it becomes
    a Restricted Subsidiary or at the time it is merged into or consolidated
    with the Company or a Restricted Subsidiary or at the time of a sale, lease
    or other disposition of the properties of such Person as an entirety or
    substantially as an entirety to the Company or a Restricted Subsidiary;

        (3) Liens securing Indebtedness Incurred pursuant to clause (b)(6) or
    (e)(iii) of the covenant described under 'Limitation on Indebtedness';

        (4) Liens securing Indebtedness of the Company or any Restricted
    Subsidiary owing to the Company or to a Restricted Subsidiary;

        (5) Liens required by any contract or statute in order to permit the
    Company or its Restricted Subsidiaries to perform any contract or
    subcontract made by it with or at the request of the United States, any
    State of the United States, another country or any department, agency or
    instrumentality of the foregoing;

        (6) Liens to secure bids, tenders, contracts (other than contracts for
    the repayment of borrowed money), leases, statutory obligations, surety and
    appeal bonds, performance or return-of-money bonds, progress payments,
    customs duties and other obligations of like nature arising in the ordinary
    course of business;

        (7) Liens on accounts receivable and related assets of the type
    specified in the definition of 'Qualified Receivables Transaction' Incurred
    in connection with a Qualified Receivables Transaction;

        (8) Liens securing Indebtedness of any Foreign Subsidiary Incurred
    pursuant to clause (b)(10) of the covenant described under 'Limitation on
    Indebtedness'; and

        (9) Any extension, renewal, refinancing, refunding or replacement (or
    successive extensions, renewals, refinancings, refundings or replacements)
    of any Lien or Indebtedness secured by any Lien, in whole or in part, that
    is referred to in the foregoing clauses (1) through (8); provided, however,
    that the principal amount of Indebtedness so secured pursuant to this clause
    (9) shall not exceed the principal amount of Indebtedness so secured (plus
    the aggregate amount of premiums, other payments, costs, and expenses
    required to be paid or Incurred in connection with such extension, renewal,
    refinancing, refunding or replacement) at the time of such extension,
    renewal, refinancing, refunding or replacement, and that such extension,
    renewal, refinancing, refunding or replacement shall be limited to all or
    the part of the property (including improvements, alterations and repairs on
    such property) subject to the encumbrance so extended, renewed, refinanced,
    refunded or replaced (plus improvements, alterations and repairs on such
    property).

    (b) In addition, the Company and any Restricted Subsidiary may, without
securing the Exchange Notes, Incur Secured Debt in an aggregate principal amount
which, together with (without duplication) (1) the aggregate principal amount of
all other Secured Debt of the Company and the Restricted Subsidiaries (other
than Indebtedness permitted to be secured under

                                       58






paragraph (a) of this covenant), (2) the aggregate Value of Sale/Leaseback
Transactions of the Company and the Restricted Subsidiaries (other than
Sale/Leaseback Transactions permitted under paragraph (a) of the covenant
described under 'Limitation on Sale/Leaseback Transactions'), and (3) the
aggregate principal amount of all Funded Debt of the Restricted Subsidiaries
(other than Funded Debt permitted to be Incurred under clauses (i) through (iv)
of paragraph (e) of the covenant described under 'Limitation on Indebtedness'),
does not at any one time exceed 15% of Consolidated Net Tangible Assets of the
Issuer.

    SEC Reports. Subsequent to June 18, 2001, the Company and the Issuer will
file with the SEC and provide the Trustee and Holders and prospective Holders
(upon request) within 15 days after it files them with the SEC, copies of its
annual report and the information, documents and other reports that are
specified in Sections 13 and 15(d) of the Exchange Act. The Company and the
Issuer also will comply with the other provisions of Section 314(a) of the TIA.

    Limitation on Lines of Business. Subsequent to June 18, 2001, the Company
will not, and will not permit any Restricted Subsidiary to, engage in any
business, other than a Permitted Business; provided, however, that the Company
or any of its Restricted Subsidiaries may acquire any Person or business which
is primarily engaged in a Permitted Business notwithstanding that such Person or
business also engages in a business which is not a Permitted Business.

    Limitation on Sale/Leaseback Transactions. (a) Subsequent to June 18, 2001,
the Company will not, and will not permit any Restricted Subsidiary to, enter
into any arrangement with any Person (other than the Company or a Restricted
Subsidiary), providing for the leasing to the Company or a Restricted Subsidiary
for a period of more than three years of any Restricted Property which has been
or is to be sold or transferred by the Company or such Restricted Subsidiary to
such Person or to any other Person (other than the Company or a Restricted
Subsidiary), to which funds have been or are to be advanced by such Person on
the security of the leased property (each such arrangement, a 'Sale/Leaseback
Transaction') unless:

        (1) the Company or such Restricted Subsidiary applies or commits to
    apply an amount equal to the Value of such Sale/Leaseback Transaction to the
    repayment, redemption or retirement (other than any mandatory repayment,
    redemption or retirement or by way of payment at maturity) within 185 days
    of the effective date of such Sale/Leaseback Transaction of Indebtedness of
    the Company or any Restricted Subsidiary which by its terms (A) matures at
    (or is extendible or renewable, at the sole option of the obligor without
    the consent of the obligee, to) a date more than 12 months after the date of
    creation of such Indebtedness, and (B) is not subordinated to the Exchange
    Notes or the Note Guarantee; or

        (2) the Company or such Restricted Subsidiary applies the net proceeds
    of the sale to investment in another Restricted Property within 185 days
    prior or subsequent to such sale.

    (b) In addition, the Company and any Restricted Subsidiary may enter into a
Sale/Leaseback Transaction with a Value which, together with (without
duplication) (1) the aggregate Value of all other Sale/Leaseback Transactions of
the Company and the Restricted Subsidiaries (other than Sale/Leaseback
Transactions permitted under paragraph (a) above), (2) the aggregate principal
amount of all Secured Debt of the Company and the Restricted Subsidiaries (other
than Indebtedness permitted to be secured under clauses (1) through (9) of
paragraph (a) of the covenant described under 'Limitation on Liens'), and (3)
the aggregate principal amount of all Funded Debt of the Restricted Subsidiaries
(other than Funded Debt permitted to be Incurred under clauses (i) through (iv)
of paragraph (e) of the covenant described under 'Limitation on Indebtedness'),
does not at the time of entering into exceed 15% of Consolidated Net Tangible
Assets of the Issuer.

    Corporate Existence. Subject to the covenant described under 'Merger and
Consolidation,' subsequent to June 18, 2001, the Company shall do or cause to be
done all things necessary to preserve and keep in full force and effect the
corporate existence and related rights and franchises (charter and statutory) of
the Company and its Restricted Subsidiaries; provided, however, that the Company
and its Restricted Subsidiaries shall not be required to preserve any such right
or franchise or the corporate existence of any such Restricted Subsidiary (other
than

                                       59






the Issuer) if the Board of Directors of the Company shall determine that the
preservation thereof is no longer necessary or desirable in the conduct of the
business of the Company and its Restricted Subsidiaries taken as a whole and
that the loss thereof would not reasonably be expected to have a material
adverse effect on the ability of the Issuer or the Company to perform its
obligations under the Exchange Notes or the Indenture.

    Payment of Taxes and Other Claims. Subsequent to June 18, 2001, the Company
shall pay or discharge or cause to be paid or discharged, on or before the date
the same shall become due and payable, (a) all taxes, assessments and
governmental charges levied or imposed upon the Company or any of its Restricted
Subsidiaries shown to be due on any return of the Company or any of its
Restricted Subsidiaries or otherwise assessed or upon the income, profits or
property of the Company or any of its Restricted Subsidiaries if failure to pay
or discharge the same could reasonably be expected to have a material adverse
effect on the ability of the Issuer or the Company to perform its obligations
under the Exchange Notes or the Indenture and (b) all lawful claims for labor,
materials and supplies, which, if unpaid, would by law become a Lien upon the
property of the Company or any of its Restricted Subsidiaries, except for any
Lien permitted to be Incurred under the covenant described under ' -- Limitation
on Liens,' if failure to pay or discharge the same could reasonably be expected
to have a material adverse effect on the ability of the Issuer or the Company to
perform its obligations under the Exchange Notes or the Indenture; provided,
however, that the Company or any of the Restricted Subsidiaries shall not be
required to pay or discharge or cause to be paid or discharged any such tax,
assessment, charge or claim whose amount, applicability or validity is being
contested in good faith by appropriate proceedings properly instituted and
diligently conducted and in respect of which appropriate reserves (in the good
faith judgment of management of the Company) are being maintained in accordance
with GAAP.

    Maintenance of Properties. Subsequent to June 18, 2001, the Company shall
cause all material properties owned by the Company or any of its Restricted
Subsidiaries or used or held for use in the conduct of their respective
businesses to be maintained and kept in good condition, repair and working order
(ordinary wear and tear excepted) and supplied with all necessary equipment and
will cause to be made all necessary repairs, renewals, replacements, betterments
and improvements thereof, all as in the reasonable judgment of the Company may
be consistent with sound business practice and necessary so that the business
carried on in connection therewith may be properly conducted at all times;
provided, however, that nothing in this covenant shall prevent the Company from
discontinuing the maintenance of any of such properties if such discontinuance
is, in the reasonable judgment of the Company, desirable in the conduct of the
business of the Company and its Restricted Subsidiaries, taken as a whole, and
not reasonably expected to have a material adverse effect on the ability of the
Issuer or the Company to perform its obligations under the Exchange Notes or the
Indenture.

    Fall-Away of Covenants. After the date (such date, the 'Fall-Away Date') on
which (a) the Exchange Notes have received ratings from both S&P and Moody's of
not lower than BBB- and Baa3, respectively, (b) no Default or Event of Default
has occurred and is continuing under the Indenture and (c) the Issuer has
delivered an Officers' Certificate to the Trustee certifying that the conditions
set forth in clauses (a) and (b) above are satisfied, the Company and the
Restricted Subsidiaries will no longer be subject to the following provisions of
the Indenture (notwithstanding that the Exchange Notes may later cease to have
such ratings):

         ' -- Limitation on Indebtedness' (other than paragraph (e) thereof and
         the clauses of paragraph (b) thereof referred to in paragraph (e)
         thereof),

         ' -- Limitation on Restricted Payments,'

         ' -- Limitation on the Sale or Issuance of Capital Stock of Restricted
         Subsidiaries,'

         ' -- Limitation on Transactions with Affiliates,'

                                       60






         ' -- Limitation on Lines of Business' and

         ' -- Merger and Consolidation' (only as to clause (3) in respect of
         each of the Company and the Issuer).

MERGER AND CONSOLIDATION

    Subsequent to June 18, 2001, the Issuer will not consolidate with or merge
with or into, or convey, transfer or lease all or substantially all its assets
to, any Person, unless:

        (1) the resulting, surviving or transferee Person (the 'Successor
    Company') will be a corporation organized and existing under the laws of the
    United States of America, any State thereof or the District of Columbia and
    the Successor Company (if not the Issuer) will expressly assume, by a
    supplemental indenture, executed and delivered to the Trustee, in form
    satisfactory to the Trustee, all the obligations of the Issuer under the
    Exchange Notes and the Indenture;

        (2) immediately after giving effect to such transaction (and treating
    any Indebtedness which becomes an obligation of the Successor Company, the
    Company or any Restricted Subsidiary as a result of such transaction as
    having been Incurred by the Successor Company, the Company or such
    Restricted Subsidiary at the time of such transaction), no Default shall
    have occurred and be continuing;

        (3) immediately after giving effect to such transaction, the Successor
    Company would be able to Incur an additional $1.00 of Indebtedness under
    paragraph (a) of the covenant described under 'Limitation on Indebtedness';
    and

        (4) the Issuer shall have delivered to the Trustee an Officers'
    Certificate and an Opinion of Counsel, each stating that such consolidation,
    merger or transfer and such supplemental indenture (if any) comply with the
    Indenture.

    The Successor Company will succeed to, and be substituted for, and may
exercise every right and power of, the Issuer under the Indenture, and the
predecessor Issuer shall be released from all of its obligations thereunder,
except in the case of a lease of all or substantially all its assets in which
case it will not be released from the obligation to pay the principal of and
interest on the Exchange Notes.

    In addition, subsequent to June 18, 2001, the Company will not consolidate
with or merge with or into, or convey, transfer or lease all or substantially
all of its assets to any Person unless:

        (1) the resulting, surviving or transferee Person (the 'Successor
    Guarantor') will be a corporation organized and existing under the laws of
    the United States of America, any State thereof or the District of Columbia,
    and such Person (if not the Company) will expressly assume, by a
    supplemental indenture, executed and delivered to the Trustee, in form
    satisfactory to the Trustee, all the obligations of the Company under the
    Note Guarantee, the Exchange Notes and the Indenture;

        (2) immediately after giving effect to such transaction (and treating
    any Indebtedness which becomes an obligation of the Successor Guarantor or
    any Restricted Subsidiary as a result of such transaction as having been
    Incurred by the Successor Guarantor or such Restricted Subsidiary at the
    time of such transaction), no Default shall have occurred and be continuing;

        (3) immediately after giving effect to such transaction, the Successor
    Guarantor would be able to Incur an additional $1.00 of Indebtedness under
    paragraph (a) of the covenant described under 'Limitation on Indebtedness';
    and

        (4) the Issuer will have delivered to the Trustee an Officers'
    Certificate and an Opinion of Counsel, each stating that such consolidation,
    merger or transfer and such supplemental indenture (if any) comply with the
    Indenture.

    The Successor Guarantor will succeed to, and be substituted for, and may
exercise every right and power of, the Company under the Indenture, and the
predecessor Company shall be

                                       61






released from all of its obligations thereunder, except in the case of a lease
of all or substantially all its assets in which case it will not be released
from the obligation to pay the principal of and interest on the Exchange Notes.

    Notwithstanding anything in the Indenture:

           (A) any Restricted Subsidiary may consolidate with, merge into or
       convey, lease, sell, assign, transfer or otherwise dispose of all or part
       of its properties and assets to the Company or a Restricted Subsidiary;

           (B) the Issuer or the Company may merge with an Affiliate
       incorporated solely for the purpose of reincorporating the Issuer or the
       Company in another jurisdiction to realize tax or other benefits; and

           (C) for purposes of this covenant, the sale by the Company or the
       Issuer of the equity interests in Millennium Petrochemicals Inc., the
       equity interests in the limited liability companies which directly or
       indirectly own the Company's equity interests in Equistar, and/or the
       Company's equity interests in Equistar will be deemed not to constitute
       the conveyance, transfer or lease of all or substantially all the assets
       of the Issuer or the Company if any such sale consists of Net Tangible
       Assets constituting 33 1/3% or less of the Consolidated Net Tangible
       Assets of the Company as of the date of the most recent publicly
       available consolidated balance sheet of the Company and its Subsidiaries.

DEFAULTS

    Each of the following is an Event of Default:

        (1) a default in any payment of interest or any Additional Amounts on
    any Note when due and payable or in any payment of liquidated damages
    continued for 30 days;

        (2) a default in the payment of principal of any Note when due and
    payable at its Stated Maturity, upon required redemption or required
    repurchase, upon declaration or otherwise;

        (3) the failure by the Company or the Issuer to comply with its
    obligations described under 'Merger and Consolidation' above;

        (4) the failure by the Company or any Restricted Subsidiary to comply
    for 30 days after notice with any of its obligations under the covenants
    described under 'Change of Control' or 'Certain Covenants' above (in each
    case, other than a failure to purchase Notes, which will constitute an Event
    of Default under clause (2) above and other than a failure to comply with
    the obligations described under 'Merger and Consolidation,' which will
    constitute an Event of Default under clause (3) above);

        (5) the failure by the Company or any Restricted Subsidiary to comply
    for 60 days after notice with its other agreements contained in the Notes or
    the Indenture;

        (6) the failure by the Company or any Restricted Subsidiary to pay any
    Indebtedness within any applicable grace period after final maturity or the
    acceleration of any such Indebtedness by the holders thereof because of a
    default if the total amount of such Indebtedness unpaid or accelerated
    exceeds $30 million or its foreign currency equivalent (the 'cross
    acceleration provision');

        (7) certain events of bankruptcy, insolvency or reorganization of the
    Company or a Significant Subsidiary (the 'bankruptcy provisions');

        (8) the rendering of any judgment or decree for the payment of money
    (other than judgments which are covered by enforceable insurance policies
    issued by reputable and creditworthy insurance companies for which coverage
    has been acknowledged in writing) in excess of $30 million or its foreign
    currency equivalent against the Company or a Restricted Subsidiary if such
    judgment or decree remains outstanding for a period of 60 days following
    such judgment and is not paid, discharged, waived or stayed and an
    enforcement proceeding thereon is commenced by any creditor (the 'judgment
    default provision'); or

                                       62






        (9) the Note Guarantee ceases to be in full force and effect (except as
    contemplated by the Indenture) or the Company or any Person acting on behalf
    of the Company denies or disaffirms the Company's obligations under the
    Indenture or Note Guarantee and such Default continues for 10 days after
    receipt of the notice specified in the Indenture.

    The foregoing will constitute Events of Default whatever the reason for any
such Event of Default and whether it is voluntary or involuntary or is effected
by operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body.

    However, a default under clauses (4), (5) or (9) will not constitute an
Event of Default until the Trustee notifies the Issuer or the Holders of at
least 25% in principal amount of the Notes then outstanding notify the Issuer
and the Trustee of the default and the Issuer or the Company, as applicable,
does not cure such default within the time specified in clauses (4), (5) or (9)
hereof after receipt of such notice.

    If an Event of Default (other than an Event of Default relating to certain
events of bankruptcy, insolvency or reorganization of the Company or the Issuer)
occurs and is continuing, the Trustee or the Holders of at least 25% in
principal amount of the Notes then outstanding by notice to the Issuer may
declare the principal of and accrued but unpaid interest on all the Notes then
outstanding to be due and payable. Upon such a declaration, such principal and
interest will be due and payable immediately. If an Event of Default relating to
certain events of bankruptcy, insolvency or reorganization of the Company or the
Issuer occurs, the principal of and interest on all the Notes then outstanding
will become immediately due and payable without any declaration or other act on
the part of the Trustee or any Holders. Under certain circumstances, the Holders
of a majority in principal amount of the Notes then outstanding may rescind any
such acceleration with respect to the Notes then outstanding and its
consequences.

    Subject to the provisions of the Indenture relating to the duties of the
Trustee, in case an Event of Default occurs and is continuing, the Trustee will
be under no obligation to exercise any of the rights or powers under the
Indenture at the request or direction of any of the Holders unless such Holders
have offered to the Trustee reasonable indemnity or security against any loss,
liability or expense. Except to enforce the right to receive payment of
principal, premium (if any) or interest when due, no Holder may pursue any
remedy with respect to the Indenture or the Notes unless:

        (1) such Holder gives to the Trustee notice that an Event of Default is
    continuing,

        (2) Holders of at least 25% in principal amount of the Notes then
    outstanding have requested the Trustee in writing to pursue the remedy,

        (3) such Holders have offered the Trustee reasonable security or
    indemnity against any loss, liability or expense,

        (4) the Trustee has not complied with such request within 60 days after
    the receipt of the request and the offer of security or indemnity, and

        (5) the Holders of a majority in principal amount of the Notes then
    outstanding have not given the Trustee a direction inconsistent with such
    request within such 60-day period.

    Subject to certain restrictions, the Holders of a majority in principal
amount of the Notes then outstanding will be given the right to direct the time,
method and place of conducting any proceeding for any remedy available to the
Trustee or of exercising any trust or power conferred on the Trustee. The
Trustee, however, may refuse to follow any direction that conflicts with law or
the Indenture or that the Trustee determines is unduly prejudicial to the rights
of any other Holder or that would involve the Trustee in personal liability.
Prior to taking any action under the Indenture, the Trustee will be entitled to
indemnification satisfactory to it in its sole discretion against all losses and
expenses caused by taking or not taking such action.

    If a Default occurs and is continuing and is known to the Trustee, the
Trustee must mail to each Holder notice of the Default within the earlier of 90
days after it occurs or 30 days after it is known to a Trust Officer or written
notice of it is received by the Trustee. Except in the case of a

                                       63






Default in the payment of principal of, premium (if any) or interest on any Note
(including required payments, if any, pursuant to the redemption provisions of
such Note), the Trustee may withhold notice if and so long as a committee of its
Trust Officers in good faith determines that withholding notice is in the
interests of the Holders. In addition, the Issuer will be required to deliver to
the Trustee, within 120 days after the end of each fiscal year of the Issuer, a
certificate indicating whether the signers thereof know of any Default that
occurred during that fiscal year. The Issuer will also be required to deliver to
the Trustee, within 30 days after the occurrence thereof, written notice of any
event which would constitute certain Events of Default, their status and what
action the Issuer is taking or proposes to take in respect thereof.

AMENDMENTS AND WAIVERS

    Subject to certain exceptions, the Indenture or the Notes may be amended
with the written consent of the Holders of a majority in principal amount of the
Notes then outstanding (including, without limitation, consents obtained in
connection with a purchase of, or tender offer or exchange offer for, Notes)
and, subject to certain exceptions, any past default or compliance with any
provisions may be waived with the consent of the Holders of a majority in
principal amount of the Notes then outstanding (including, without limitation,
consents obtained in connection with a purchase of, or tender offer or exchange
offer for, Notes). However, without the consent of each Holder of an outstanding
Note affected, no amendment may, among other things:

        (1) reduce the amount of Notes whose Holders must consent to an
    amendment,

        (2) reduce the stated rate of or extend the stated time for payment of
    interest or any liquidated damages on any Note,

        (3) reduce the principal of or extend the Stated Maturity of any Note,

        (4) reduce the premium payable upon the redemption of any Note or change
    the time at which any Note may be redeemed as described under 'Optional
    Redemption' above,

        (5) make any Note payable in money other than that stated in the Note,

        (6) impair the right of any Holder to receive payment of principal of,
    and interest or any liquidated damages on, such Holder's Notes on or after
    the due dates therefor or to institute suit for the enforcement of any
    payment on or with respect to such Holder's Notes,

        (7) make any change in the amendment provisions which require each
    Holder's consent or in the waiver provisions or

        (8) modify the Note Guarantee in any manner adverse to the Holders.

    Without the consent of any Holder, the Issuer, the Company and the Trustee
may amend the Indenture to, among other things:

         cure any ambiguity, omission, defect or inconsistency,

         provide for the assumption by a successor corporation of the
         obligations of the Issuer or the Company under the Indenture,

         provide for uncertificated Notes in addition to or in place of
         certificated Notes (provided, however, that the uncertificated Notes
         are issued in registered form for purposes of Section 163(f) of the
         Code, or in a manner such that the uncertificated Notes are described
         in Section 163(f)(2)(B) of the Code),

         add additional Guarantees with respect to the Notes,

         secure the Notes,

         add to the covenants of the Company and its Subsidiaries for the
         benefit of the Holders or to surrender any right or power conferred
         upon the Company or the Issuer,

         make any change that does not adversely affect the rights of any
         Holder, subject to the provisions of the Indenture,

         provide for the issuance of the Exchange Notes,

                                       64






         to evidence and provide the acceptance of the appointment of a
         successor Trustee under the Indenture, or

         comply with any requirement of the SEC in connection with the
         qualification of the Indenture under the TIA.

    The consent of the Holders will not be necessary to approve the particular
form of any proposed amendment. It will be sufficient if such consent approves
the substance of the proposed amendment.

    After an amendment becomes effective, the Issuer is required to mail to
Holders a notice briefly describing such amendment. However, the failure to give
such notice to all Holders, or any defect in the notice, will not impair or
affect the validity of the amendment.

DEFEASANCE

    The Company and the Issuer may at any time terminate all their obligations
under the Notes and the Indenture ('legal defeasance'), except for certain
obligations, including those respecting the defeasance trust and obligations to
register the transfer or exchange of the Notes, to replace mutilated, destroyed,
lost or stolen Notes and to maintain a registrar and paying agent in respect of
the Notes.

    In addition, the Company and the Issuer may at any time terminate:

        (1) their obligations under the covenants described under 'Certain
    Covenants,' and

        (2) the operation of the cross-acceleration provision, the bankruptcy
    provisions with respect to Significant Subsidiaries and the judgment default
    provision described under 'Defaults' above and the limitations contained in
    clause (3) under the first paragraph of 'Merger and Consolidation' above
    ('covenant defeasance').

    In the event that the Company and the Issuer exercise their legal defeasance
option or their covenant defeasance option, the Company will be released from
all of its obligations with respect to the Note Guarantee.

    The Company and the Issuer may exercise their legal defeasance option
notwithstanding their prior exercise of the covenant defeasance option. If the
Company and the Issuer exercise their legal defeasance option, payment of the
Notes may not be accelerated because of an Event of Default with respect
thereto. If the Company and the Issuer exercise their covenant defeasance
option, payment of the Notes may not be accelerated because of an Event of
Default specified in clause (4), (6), (7) (with respect only to Significant
Subsidiaries) or (8) (with respect only to Significant Subsidiaries) under
'Defaults' above or because of the failure of the Issuer to comply with clause
(3) under the first paragraph of 'Merger and Consolidation' above.

    In order to exercise either defeasance option, the Issuer must irrevocably
deposit in trust (the 'defeasance trust') with the Trustee money in an amount
sufficient or U.S. Government Obligations, the principal of and interest on
which will be sufficient, or a combination thereof sufficient, to pay the
principal, premium (if any) and interest on, and liquidated damages, if any, in
respect of the Notes to redemption or maturity, as the case may be, and must
comply with certain other conditions, including delivery to the Trustee of an
Opinion of Counsel to the effect that Holders will not recognize income, gain or
loss for Federal income tax purposes as a result of such deposit and defeasance
and will be subject to Federal income tax on the same amounts and in the same
manner and at the same times as would have been the case if such deposit and
defeasance had not occurred (and, in the case of legal defeasance only, such
Opinion of Counsel must be based on a ruling of the Internal Revenue Service or
other change in applicable Federal income tax law).

NO PERSONAL LIABILITY OF DIRECTORS, OFFICERS, EMPLOYEES AND STOCKHOLDERS

    No director, officer, employee, incorporator or stockholder of the Issuer or
the Company, as such, shall have any liability for any obligations of the Issuer
or the Company under the

                                       65






Exchange Notes or the Indenture or for any claim based on, in respect of, or by
reason of, such obligations or their creation. Each Holder by accepting an
Exchange Note waives and releases all such liability. The waiver and release are
part of the consideration for issuance of the Exchange Notes. Such waiver may
not be effective to waive liabilities under the federal securities laws and it
is the view of the SEC that such a waiver is against public policy.

CONCERNING THE TRUSTEE

    The Bank of New York is the Trustee under the Indenture and has been
appointed by the Issuer as registrar and paying agent with regard to the Notes.
The Bank of New York is a lender under our bank credit agreement and the trustee
under the 7% Senior Notes due November 15, 2006 and the 7 5/8% Senior Debentures
due November 15, 2026 of the Issuer, guaranteed by the Company.

GOVERNING LAW

    The Indenture is, and the Exchange Notes will be, governed by, and construed
in accordance with, the laws of the State of New York without giving effect to
applicable principles of conflicts of law to the extent that the application of
the law of another jurisdiction would be required thereby.

       Indebtedness since the beginning of such period that remains outstanding
       on such date of determination or if the transaction giving rise to the
       need to calculate the Consolidated Coverage Ratio is an Incurrence of
       Indebtedness, EBITDA and Consolidated Interest Expense for such period
       shall be calculated after giving effect on a pro forma basis to such
       Indebtedness as if such Indebtedness had been Incurred on the first day
       of such period and the discharge of any other Indebtedness repaid,
       repurchased, defeased or otherwise discharged with the proceeds of such
       new Indebtedness as if such discharge had occurred on the first day of
       such period,

       repurchased, defeased or otherwise discharged any Indebtedness since the

       such Asset Disposition for such period or increased by an amount equal to
       the EBITDA (if negative) directly attributable thereto for such period
       and Consolidated Interest Expense for such period shall be reduced by an

       Restricted Subsidiary (by merger or otherwise) shall have made an
       Investment in any Restricted Subsidiary (or any Person that becomes a

       acquisition of assets occurring in connection with a transaction causing
       a calculation to be made hereunder, which constitutes all or
       substantially all of an operating unit of a

                             BOOK-ENTRY PROCEDURES

    Upon issuance, all book-entry exchange notes will be represented by one or
more fully registered global notes, without coupons. Each global note will be
deposited with, or on behalf of, DTC, and will be registered in the name of DTC
or a nominee of DTC.

    DTC has advised Millennium America that it is (i) a limited purpose trust
company organized under the laws of the State of New York, (ii) a 'banking
organization' within the meaning of the New York Banking Law, (iii) a member of
the Federal Reserve System, (iv) a 'clearing corporation' within the meaning of
the Uniform Commercial Code, as amended, and (v) a 'clearing agency' registered
pursuant to Section 17A of the Exchange Act. DTC was created to hold securities
for its participants and facilitates the clearance and settlement of securities
transactions between participants through electronic book-entry changes to the
accounts of its participants, thereby eliminating the need for physical transfer
and delivery of certificates. DTC's participants include securities brokers and
dealers (including the initial purchasers), banks and trust companies, clearing
corporations and certain other organizations. Indirect access to DTC's system is
also available to other entities such as banks, brokers, dealers and trust
companies, or indirect participants that clear through or maintain a custodial
relationship with a participant, either directly or indirectly. Investors who
are not participants may beneficially own securities held by or on behalf of DTC
only through participants or indirect participants. The ownership interest and
transfer of ownership interest of each actual purchaser of each security held by
or on behalf of DTC are recorded on the records of the participants and the
indirect participants.

    We expect that pursuant to procedures established by DTC

        (1) upon deposit of the global notes, DTC or its custodian will credit
    on its internal system portions of the global notes which shall be comprised
    of the corresponding respective amount of the global notes to the respective
    accounts of persons who have accounts with such depositary and

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

    Noteholders may hold their interests in a global note directly through DTC
if they are participants in such system, or indirectly through organizations
which are participants in such system.

    The laws of some jurisdictions may require that certain purchasers of
securities take physical delivery of such securities in definitive form.
Accordingly, the ability to transfer interests in the notes represented by a
global note to such persons may be limited. In addition, because DTC can act
only on behalf of its participants, who in turn act on behalf of persons who
hold interests through participants, the ability of a person having an interest
in exchange notes represented by a global note to pledge or transfer such
interest to persons or entities that do not participate in DTC's system, or to
otherwise take actions in respect of such interest, may be affected by the lack
of a physical definitive security in respect of such interest.

    So long as DTC or its nominee is the registered owner or holder of any of
the exchange notes, DTC or such nominee will be considered the sole owner or
holder of such exchange notes represented by such global notes for all purposes
under the indenture and under the exchange notes represented thereby. No
beneficial owner of an interest in the global notes will be able to transfer
such interest except in accordance with the applicable procedures of DTC in
addition to those provided for under the indenture.

    Payments of the principal, premium, if any, and interest on the exchange
notes represented by the global notes will be made to DTC or its nominee, as the
case may be, as the registered owner of the exchange notes represented by the
global notes. Neither we or the trustee will have any responsibility or
liability for any aspect of the records relating to or payments made on account
of beneficial ownership interests in the global notes or for maintaining,
supervising or reviewing any records relating to such beneficial ownership
interest.

                                       83






    We expect that DTC or its nominee, upon receipt of any payment of the
principal, premium or interest on the exchange notes represented by the global
notes, will credit participants' accounts with payments in amounts proportionate
to their respective beneficial interests in the global notes as shown on the
records of DTC or its nominee. We also expect that payments by participants to
owners of beneficial interests in the global notes held through such
participants will be governed by standing instructions and customary practice as
is now the case with securities held for the accounts of customers registered in
the names of nominees for such customers. Such payment will be the
responsibility of such participants. Transfers between participants in DTC will
be effected in accordance with DTC rules and procedures and will be settled in
same-day funds.

    DTC has advised us that it will take any action permitted to be taken by a
holder of exchange notes (including the presentation of exchange notes for
exchange as described below) only at the direction of one or more participants
to whose account the DTC interests in the global notes are credited and only in
respect of the aggregate principal amount of as to which such participant or
participants has or have given such direction.

    Although DTC is expected to follow the foregoing procedures in order to
facilitate transfers of interests in the global notes among participants of DTC,
DTC is under no obligation to perform such procedures, and such procedures may
be discontinued at any time. Neither we or the trustee will have any
responsibility for the performance by DTC or its direct or indirect participants
of their respective obligations under the rules and procedures governing their
operations.

    Interests in the global notes will be exchanged for physical delivery of
certificates only if

        (1) DTC is at any time unwilling or unable to continue as depositary for
    the global notes, or DTC ceases to be registered as a clearing agency under
    the Exchange Act and a successor depositary is not appointed by us within
    90 days; or

        (2) an event of default with respect to the exchange notes will have
    occurred and be continuing; or

        (3) Millennium America, at its option, notifies the trustee in writing
    that it elects to cause the issuance of exchange notes in definitive form
    under the indenture.

    The information in this section concerning DTC and DTC's book-entry system

                       FEDERAL INCOME TAX CONSIDERATIONS

    The following is a summary of the material U.S. federal income tax
considerations relating to the exchange of unregistered notes for exchange notes
in the exchange offer. It does not contain a complete analysis of all the
potential tax considerations relating to the exchange. This summary is limited
to holders of unregistered notes who hold the unregistered notes as 'capital
assets' (in general, assets held for investment). Special situations, such as
the following are not addressed:

     tax consequences to holders who may be subject to special tax treatment,
     such as tax-exempt entities, dealers in securities or currencies, financial
     institutions, insurance companies, regulated investment companies, traders
     in securities that elect to use a mark-to-market method of accounting for
     their securities holdings or corporations that accumulate earnings to avoid
     U.S. federal income tax;

     tax consequences to persons holding notes as part of a hedging, integrated,
     constructive sale or conversion transaction or a straddle or other risk
     reduction transaction;

     tax consequences to holders whose 'functional currency' is not the U.S.
     dollar;

     tax consequences to persons who hold notes through a partnership or similar
     pass-through entity;

     alternative minimum tax consequences, if any; or

     any state, local or foreign tax consequences.

    The discussion below is based upon the provisions of the Internal Revenue
Code of 1986, existing and proposed Treasury regulations promulgated thereunder,
and rulings, judicial decisions and administrative interpretations thereunder,
as of the date hereof. Those authorities may be changed, perhaps retroactively,
so as to result in U.S. federal income tax consequences different from those
discussed below.

CONSEQUENCES OF TENDERING UNREGISTERED NOTES

    The exchange of your unregistered notes for exchange notes in the exchange
offer will have no federal income tax consequences to you. For example, there
would be no change in your tax basis, and your holding period would carry over
to the exchange notes. In addition, the federal income tax consequences of
holding and disposing of your exchange notes would also be the same as those
applicable to your unregistered notes.

    THE PRECEDING DISCUSSION OF CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS
IS FOR GENERAL INFORMATION ONLY AND IS NOT TAX ADVICE. ACCORDINGLY, EACH
INVESTOR SHOULD CONSULT ITS OWN TAX ADVISOR AS TO PARTICULAR TAX CONSEQUENCES TO
IT OF EXCHANGING UNREGISTERED NOTES FOR EXCHANGE NOTES, INCLUDING THE
APPLICABILITY AND EFFECT OF ANY STATE, LOCAL OR FOREIGN TAX LAWS, AND OF ANY
PROPOSED CHANGES IN APPLICABLE LAWS.

                              PLAN OF DISTRIBUTION

    Each broker-dealer that receives exchange notes for its own account pursuant
to the exchange offer must acknowledge that it will deliver a prospectus in
connection with any resale of such exchange notes. This prospectus, as it may be
amended or supplemented from time to time, may be used by a broker-dealer in
connection with resales of exchange notes received in exchange for outstanding
unregistered notes where such outstanding unregistered notes were acquired as a
result of market-making activities or other trading activities. We have agreed
that, for a period of 180 days after the expiration date, we will make this
prospectus, as amended or supplemented, available to any broker-dealer for use
in connection with any such resale. In addition, until 40 days after the later
of the commencement of the offering and the issue date, all dealers effecting
transactions in the exchange notes may be required to deliver a prospectus.

    We will not receive any proceeds from any sale of exchange notes by
broker-dealers. Exchange notes received by broker-dealers for their own account
pursuant to the exchange offer may be sold from time to time in one or more
transactions in the over-the-counter market, in negotiated transactions, through
the writing of options on the exchange notes or a combination of such methods of
resale, at market prices prevailing at the time of resale, at prices related to
such prevailing market prices or at negotiated prices. Any such resale may be
made directly to purchasers or to or through brokers or dealers who may receive
compensation in the form of commissions or concessions from any such
broker-dealer or the purchasers of any such exchange notes. Any broker-dealer
that resells exchange notes that were received by it for its own account
pursuant to the exchange offer and any broker or dealer that participates in a
distribution of such exchange notes may be deemed to be an 'underwriter' within
the meaning of the Securities Act and any profit on any such resale of exchange
notes and any commission or concessions received by any such persons may be
deemed to be underwriting compensation under the Securities Act. The letter of
transmittal states that, by acknowledging that it will deliver and by delivering
a prospectus, a broker-dealer will not be deemed to admit that it is an
'underwriter' within the meaning of the Securities Act.

    For a period of 180 days after the expiration date we will promptly send
additional copies of this prospectus and any amendment or supplement to this
prospectus to any broker-dealer that requests such documents in the letter of
transmittal. We and Millennium Chemicals have agreed to pay all expenses
incident to the exchange offer (including the expenses of one counsel for the
holders of the outstanding unregistered notes) other than commissions or
concessions of any broker-dealers and will indemnify the holders of the
outstanding unregistered notes (including any broker-dealers) against certain
liabilities, including liabilities under the Securities Act.

                                 LEGAL MATTERS

    The validity and enforceability of the exchange notes and the note guarantee
of Millennium Chemicals will be passed upon for us by C. William Carmean,
attorney-at-law. Mr. Carmean is the Senior Vice President, General Counsel and
Secretary of Millennium America and Millennium Chemicals and is a director of
Millennium America.

                           FORWARD-LOOKING STATEMENTS

    The statements contained in this offering prospectus that are not historical
facts are or may be deemed to be 'forward-looking statements' as defined in the
Private Securities Litigation Reform Act of 1995. Some of these statements can
be identified by the use of forward-looking terminology such as 'prospects,'
'outlook,' 'believes,' 'estimates,' 'intends,' 'may,' 'will,' 'should,'
'anticipates,' 'expects' or 'plans,' or the negative or other variation of these
or similar words, or by discussion of trends and conditions, strategy or risks
and uncertainties. In addition, from time to time we or our representatives have
made or may make forward-looking statements orally or in writing. Furthermore,
such forward-looking statements may be included in various filings that we make
with the SEC or press releases or oral statements made by or with the approval
of one of our authorized executive officers.

    These statements are only present expectations and assumptions about future
events. Actual events or results may differ materially. Factors that could cause
such a difference include:

     the cyclicality and volatility of the chemical industries in which we and
     Equistar operate, particularly fluctuations in the demand for ethylene, its
     derivatives and acetyls and the sensitivity of these industries to capacity
     additions;

     general economic conditions in the geographic regions where we and Equistar
     generate sales, and the impact of government regulation and other external
     factors, in particular, the events in the Middle East;

     the ability of Equistar to distribute cash to its partners and
     uncertainties arising from our shared control of Equistar and our
     contractual commitments regarding possible future capital contributions to
     Equistar;

     changes in the cost of energy and raw materials, particularly natural gas
     and ethylene, and our and Equistar's ability to pass on cost increases to
     our respective customers;

     the ability of raw material suppliers to fulfill their commitments;

     our and Equistar's ability to achieve their productivity improvement, cost
     reduction and working capital targets, and the occurrence of operating
     problems at our or Equistar's manufacturing facilities;

     risks of doing business outside the United States, including currency
     fluctuations;

     the cost of compliance with the extensive environmental regulations
     affecting the chemical industry and exposure to liabilities for
     environmental remediation and other environmental matters relating to our
     and Equistar's current and former operations;

     pricing and other competitive pressures;

     legal proceedings relating to present and former operations (including
     proceedings based on alleged exposure to lead-based paints and lead
     pigments, asbestos and other materials), ongoing or future tax audits and
     other claims;

     our substantial indebtedness and its impact on our cash flow, business
     operations and ability to obtain additional financing.

    We undertake no obligation to update any forward-looking statement, whether
as a result of new information, future events or otherwise. All subsequent
written and oral forward-looking statements attributable to us or persons acting
on our behalf are expressly qualified in their entirety by the cautionary
statements contained in this offering memorandum.

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

    Generally, Section 145 of the General Corporation Law of the State of
Delaware (the 'GCL'), permits a corporation to indemnify certain persons made a
party to an action by reason of the fact that such person is or was a director,
officer, employee or agent of the corporation or is or was serving at the
request of the corporation as a director, officer, employee or agent of another
corporation or enterprise. To the extent that person has been successful in any
such matter, that person shall be indemnified against expenses actually and
reasonably incurred by him. In the case of an action by or in the right of the
corporation, no indemnification may be made in respect of any matter as to which
that person was adjudged liable unless and only to the extent that the Delaware
Court of Chancery or the court in which the action was brought determines that,
despite the adjudication of liability, that person is fairly and reasonably
entitled to indemnity for proper expenses.

    The by-laws of each of the Registrants provide for indemnification of the
Registrants' respective officers and directors to the fullest extent permitted
by law.

    Section 102(b)(7) of the GCL enables a Delaware corporation to include a
provision in its certificate of incorporation limiting a director's liability to
the corporation or its stockholders for monetary damages for breaches of
fiduciary duty as a director. Each of the Registrants have adopted provisions in
their respective certificates of incorporation that provide for such limitation
to the fullest extent permitted under Delaware law.

    The directors and officers of each of the Registrants are covered by
insurance policies indemnifying against certain liabilities, including certain
liabilities arising under the Securities Act of 1933, which might be incurred by
them in such capacities and against which they may not be indemnified by the
Registrants.

    (B) FINANCIAL STATEMENT SCHEDULES

    All schedules for which provision is made in the applicable accounting
regulations of the Securities and Exchange Commission have been omitted because
they are not required, are inapplicable or the required information has already
been provided elsewhere or incorporated by reference in this registration
statement.

ITEM 22. UNDERTAKINGS

    (a) The undersigned Registrants hereby undertake to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Items 4, 10(b), 11 or 13 of this form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the Registration Statement through the
date of responding to the request.

    (b) The undersigned Registrants hereby undertake to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.

    (c) The undersigned Registrants hereby undertake that, for purposes of
determining any liability under the Securities Act, each filing of the
Registrants' respective annual report pursuant to Section 13(a) or

                                      II-2






15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing
of an employee benefit plan's annual report pursuant to Section 15(d) of the
Exchange Act) that is incorporated by reference in the registration statement
shall be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.

    (d) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Registrants pursuant to the foregoing provisions, or otherwise, the Registrants
have been advised that in the opinion of the SEC such indemnification is against
public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the Registrants of expenses incurred or
paid by a director, officer or controlling person of the Registrants in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrants will, unless in the opinion of their counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether indemnification by them is against
public policy as expressed in the Securities Act and will be governed by the
final adjudication of that issue.

    (e) The undersigned registrant hereby undertakes:

        (1) To file, during any period in which offers or sales are being made,
    a post-effective amendment to this registration statement:

           (i) To include any prospectus required by Section 10(a)(3) of the
       Securities Act of 1933;

           (ii) To reflect in the prospectus any facts or events arising after
       the effective date of the registration statement (or the most recent
       post-effective amendment thereof) which, individually or in the
       aggregate, represent a fundamental change in the information set forth in
       the registration statement. Notwithstanding the foregoing, any increase
       or decrease in volume of securities offered (if the total dollar value of
       securities offered would not exceed that which was registered) and any
       deviation from the low or high end of the estimated maximum offering
       range may be reflected in the form of prospectus filed with Commission
       pursuant to Rule-424(b) if, in the aggregate, the changes in volume and
       price represent no more than a 20 percent change in the maximum aggregate
       offering price set forth in the 'Calculation of Registration Fee' table
       in the effective registration statement; and

           (iii) To include any material information with respect to the plan of
       distribution not previously disclosed in registration statement or any
       material change to such information in the registration statement.

        (2) That, for the purpose of determining any liability under the
    Securities Act of 1933, each such post-effective amendment shall be deemed
    to be a new registration statement relating to the securities offered
    therein, and the offering of such securities at that time shall be deemed to
    be the initial bona fide offering thereof.

        (3) To remove from registration by means of a post-effective amendment
    any of the securities being registered which remain unsold at the
    termination of the offering.

                                      II-3
